                          (iv) to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

                          (v) to approve forms of agreement for use under the

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

                          (vii) to 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 shall have declined since the date the Option was
granted;

                          (viii) to institute an Option Exchange Program;

                          (ix) to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                          (x) 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;

                          (xi) to modify or amend each Option (subject to
Section 14(b) of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options longer than is otherwise
provided for in the Plan;

                          (xii) to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option previously
granted by the Administrator;

                          (xiii) to determine the terms and restrictions
applicable to Options;

                          (xiv) 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 the amount required to be withheld. The Fair Market Value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined. All elections by an Optionee to have Shares
withheld for this purpose shall be made in such form and under such conditions
as the Administrator may deem necessary or advisable; and

                          (xv) to make all other determinations deemed necessary
or advisable for administering the Plan.

<PAGE>   5

               (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5. Eligibility. Options may be granted to Service Providers except
Officers and Directors; provided, however, that Options may be granted to
Officers in connection with the Officer's initial employment by the Company.

        6. Limitation. Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

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

        8. Term of Option. The term of each Option shall be stated in the Option
Agreement.

        9. Option Exercise Price and Consideration.

               (a) Exercise Price. The per share exercise price for the Shares
to be issued pursuant to exercise of an Option shall be determined by the
Administrator.

               (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

               (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:

                          (i) cash;

                          (ii) check;

                          (iii) promissory note;

                          (iv) other Shares which (A) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six months on the date of surrender, and (B) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                          (v) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;

                                       5
<PAGE>   6

                          (vi) a reduction in the amount of any Company
liability to the Optionee, including any liability attributable to the
Optionee's participation in any Company-sponsored deferred compensation program
or arrangement;

                          (vii) such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws; or

                          (viii) any combination of the foregoing methods of
payment.

        10. Exercise of Option.

               (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. An Option may not be exercised for a fraction of
a Share.

                      An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

                      Exercising an Option in any manner shall decrease the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

               (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                                       6
<PAGE>   7

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

               (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

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

        11. Non-Transferability of Options. Unless determined otherwise by the
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

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

               (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and 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

                                       7
<PAGE>   8

dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option 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 vested and
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, 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 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.

                                       8
<PAGE>   9

        13. Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

        14. Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

               (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
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.

        15. Conditions Upon Issuance of Shares.

               (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with 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 Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

        16. 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.

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

               (a) Grant of Option. The Plan Administrator of the Company hereby
grants to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 14(b) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

               (b) Exercise of Option.

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

                          (ii) Method of Exercise. This Option is exercisable by
delivery of an exercise notice, in the form attached as Exhibit A (the "Exercise
Notice"), which shall state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the "Exercised
Shares"), and such other representations and agreements as may be required by
the Company pursuant to the provisions of the Plan. The Exercise Notice shall be
completed by the Optionee and delivered to [TITLE]. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by such aggregate Exercise
Price.

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

               (c) 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:

                                      -2-
<PAGE>   12

                          (i) cash;

                          (ii) check;

                          (iii) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan; or

                          (iv) surrender of other Shares which (i) in the case
of Shares acquired upon exercise of an option, have been owned by the Optionee
for more than six (6) months on the date of surrender, AND (ii) have a Fair
Market Value on the date of surrender equal to the aggregate Exercise Price of
the Exercised Shares.

               (d) Non-Transferability of Option. This Option may not be
transferred in any manner otherwise than by will or by the laws of descent or
distribution and may be exercised during the lifetime of Optionee only by the
Optionee. The terms of the Plan and this Option Agreement shall be binding upon
the executors, administrators, heirs, successors and assigns of the Optionee.

               (e) Term of Option. This Option may be exercised only within the
term set out in the Notice of Grant, and may be exercised during such term only
in accordance with the Plan and the terms of this Option Agreement.

               (f) Tax Consequences. Some of the federal tax consequences
relating to this Option, as of the date of this Option, are set forth below.
THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE. THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING
THIS OPTION OR DISPOSING OF THE SHARES.

                          (i) Exercising the Option. The Optionee may incur
regular federal income tax liability upon 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
Exercised Shares on the date of exercise over their aggregate Exercise Price. If
the Optionee is an Employee or a former Employee, the Company will be required
to withhold from his or her compensation or collect from Optionee and pay to the
applicable taxing authorities an amount in cash equal to a percentage of this
compensation income at the time of exercise, and may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

                          (ii) Disposition of Shares. If the Optionee holds NSO
Shares for at least one year, any gain realized on disposition of the Shares
will be treated as long-term capital gain for federal income tax purposes.

               (g) 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

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.

               (h) 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 (AND
NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES

TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A

NOT INTERFERE 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.

<PAGE>   3

        3.     ELIGIBILITY

        Participation in the Plan shall be limited to Participants who are
designated from time to time by the Committee. Participation shall be voluntary
and the extent to which any Participant shall be entitled to participate in the
Plan shall be determined by the Committee.

        4.     PRICE FOR OPTION SHARES

        The Committee shall advise each Participant designated to participate in
the Plan of the number of Option Shares such Participant is entitled to purchase
and the Option Price at which the Option Shares may be purchased and the Vesting
Period. The Option Price at which the Option Shares may be purchased under the
Plan shall be fixed by the Committee based upon the Fair Market Value of the
Common Shares. The Committee may impose performance thresholds which will need
to be met prior to vesting of any Options granted.

        5.     EXERCISE

        Options granted under the Plan must be exercised within such period as
fixed by the Committee, not exceeding 10 years from the Date of Grant, failing
which the Participant's right to purchase such Option Shares lapses.
Notwithstanding any other provision in this Plan, unless otherwise determined by
the Committee, no options may be exercised unless the Option Shares are publicly
traded or control of the Company has been acquired in a takeover transaction.
Subject to the foregoing, the Vesting Periods during which Options or a portion
thereof vest and may be exercised by the Participant shall be set forth in the
Stock Option Agreement to be executed by the Participant, in the form attached
hereto as Appendix "A," as amended by the Company and the Participant.

        Notwithstanding the Vesting Period set forth in the Stock Option
Agreement, the Committee may, in its sole discretion, by written notice to any
Participant, accelerate the vesting of all or any of the Options such that the
Options become immediately fully vested. In such circumstances, the Committee
may by written notice compel the Participant to exercise the Options within 30
days of the date of such written notice to exercise, failing which the
Participant's right to purchase such Option Shares lapses.

        The Committee in its discretion may require that the exercise of an
Option shall be subject to the Option holder signing a counterpart of the then
existing shareholders agreement of the Company or any other agreement which is
to apply to Option holders.

        6.     PAYMENT

        Subject to Article 5 above, the Participant from time to time and at any
time after the vesting of any Options and prior to the lapse of such Options,
may elect to purchase all or a portion of the Option Shares available for
purchase by lump sum payment by delivering to the Company at its head office, a
completed stock option purchase form in the form attached hereto as Appendix
"A.1". Payment may be made by cash, certified cheque, bank draft, money order or
the equivalent payable to the order of Netergy in United States dollars.

                                      -3-
<PAGE>   4

        7.     SHARE CERTIFICATE

        Upon exercise of the Option and payment in full of the purchase price
the Company shall cause to be delivered to the Participant within a reasonable
period of time a duplicate certificate or certificates in the name of the
Participant representing the number of Option Shares the Participant has
purchased. The original share certificate shall be held in trust by the Company
for delivery to the holder when the shares are to be transferred, as authorized
by the Plan.

        8.     ADJUSTMENT IN SHARES

        The Committee will make appropriate adjustments in the number of Common
Shares subject to the Plan and, as regards Options granted or to be granted, in
the number of Common Shares optioned and in the Option Price, to give effect to
the adjustments in the number of Common Shares resulting from sub-divisions,
consolidations or re-classification of the Common Shares or other relevant
changes (an "Event") in the authorized or issued capital of the Parent. No
fractions of shares need be issued on the exercise of the Options and,
accordingly, if after an Event a Participant has a right to a fraction of a
share, he will only have the right to purchase the next lower whole number of
shares and no payment or other adjustment will be effected with respect to the
right to participate in the fraction which was not taken into account. When an
Event occurs, the number of shares that the Board of Directors authorized under
the Plan shall be adjusted appropriately.

        In the event that the Parent proposes to liquidate, dissolve or wind-up,
the Company may give written notice thereof to each Participant holding Options
under the Plan and in such case Participants shall be entitled to exercise all
or a portion of the Options granted to such Participants, whether or not such
Options have vested, within the 30-day period next following the giving of such
notice. Upon the expiration of such 30 day period, all rights of the
Participants to the Option Shares or to the exercise of the Options shall
terminate and cease to have any further force and effect.

        In the event of a merger of the Parent with or into another corporation,
or the sale of substantially all of the assets of the Parent, 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 the
Option, the Option shall fully vest and the Participant shall have the right to
exercise the Option as to all of the Option Shares, including Option Shares
which 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 Committee shall notify the Participant in writing
or electronically that the Option shall be fully vested and 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 such merger or
sale of assets, the option or right confers the right to purchase or receive,
for each share of Option Shares, 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 Shares 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 Common Shares); provided, however, that if such
consideration received in the merger or sale of

                                      -4-
<PAGE>   5

assets is not solely common stock of the successor corporation or its parent,
the Committee 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 Shares 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 Shares in the merger or sale of assets.

        9.     TERMINATION OF PARTICIPANT FOR ANY REASON

        Subject to Article 5 above, in the event that an Employee's employment
with the Company, the Parent or any of their subsidiaries is terminated for any
reason, a Director shall cease to be a Director on the Board of Directors for
any reason or a Service Provider ceases to provide services to the Company, the
Participant or the Participant's legal representative, as the case may be, may
elect to purchase at the Option Price all or a portion of the remaining Option
Shares subject to Options that have vested at the time such employment, position
on the Board of Directors or services with the Company is terminated at any time
during the 30 day period, or such later date as determined by the Board of
Directors, following the date of such termination of employment or position on
the Board of Directors or termination of services of a Service Provider (but in
no event after the lapse of any Options held), failing which the exercise of any
such Options shall lapse. Any Options not vested shall lapse, unless otherwise
determined by the Committee at the time the Employee's employment is terminated,
the Director ceases to be a Director on the Board of Directors or the Service
Provider ceases to provide services to the Company. To the extent the Common
Shares are not listed on any Exchange, the Company may, at any time within one
year after termination, elect to purchase at the same Option Price paid by the
Participant or the Participant's legal representative all of the Common Shares
purchased by such Participant under this Plan. For the purposes of this Plan,
the transfer of the Employee's employment to the Company, the Parent or to any
subsidiary of the Company or the Parent shall not be considered a termination of
employment and the Employee's rights under the Option shall be the same as if
such transfer had not occurred.

        10.    TRANSFER AND ASSIGNMENT

        The Participant's rights under Options granted under the Plan are not
assignable or transferable by the Participant or subject to any other
alienation, sale, pledge or encumbrance by such Participant during the
Participant's lifetime and therefore the Options are exercisable during the
Participant's lifetime only by the Participant. The obligations of each
Participant shall be binding on his or her heirs, executors and administrators.

        11.    EMPLOYMENT AND BOARD OF DIRECTORS POSITION NON-CONTRACTUAL

        The granting of an Option to a Participant under the Plan does not
confer upon the Participant any right to continue in the employment of the
Company or any subsidiary of the Company or as a member of the Board of
Directors or as a Service Provider, as the case may be, nor does it interfere in
any way with the rights of the Employee or of the Company's rights to terminate
the Employee's employment at any time or of the shareholders' right to elect
Directors.

                                      -5-
<PAGE>   6

        12.    RIGHTS AS SHAREHOLDERS

        Participants shall not have any rights as a shareholder with respect to
Option Shares until full payment has been made to the Parent and a share
certificate or share certificates have been duly issued.

        13.    ADMINISTRATION OF THE PLAN

        The Plan shall be administered by the Committee. The Committee shall
have the power to interpret and construe the terms and conditions of the Plan
