upon exercise of either an Option or Stock Purchase Right, shall not be returned

Plan, except that if Shares or Restricted Stock are repurchased by the Company
at their original purchase price, such Shares shall become available for future
grant under the Plan.

     4. ADMINISTRATION OF THE PLAN.

          (a) ADMINISTRATOR. The Plan shall be administered by the Board or a
Committee appointed by the Board, which Committee shall be constituted to
comply with Applicable Laws.

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

                                       3

<PAGE>

               (i)    to determine the Fair Market Value;

               (ii)   to select the Service Providers to whom Options and
Stock Purchase Rights may from time to time be grated hereunder;

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

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

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

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

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

               (viii) to initiate an Option Exchange Program;

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

               (x)    to allow Optionees to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares to be issued upon
exercise of an Option or Stock Purchase Right that number of Shares having a
Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date
that the amount of tax to be withheld is to be determined. All elections by
Optionees to have Shares withheld for this purpose shall be made in such form
and under such conditions as the Administrator may deem necessary or
advisable; and

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

          (c) EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees.

                                        4

     5. ELIGIBILITY.

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

          (b) Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year
(under all plans of the Company and any Parent or Subsidiary) exceeds
$100,000, such Options shall be treated as Nonstatutory Stock Options. For
purposes of this Section 5(b), Incentive Stock Options shall be taken into
account in the order in which they were granted. The Fair Market Value of the
Shares shall be determined as of the time the Options with respect to such
Shares is granted.

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

     6. TERM OF PLAN. Subject to Section 19 below, the Plan shall become
effective upon its adoption by the Board. It shall continue in effect for a
term of ten (10) years unless sooner terminated under Section 15 of the Plan.

     7. TERM OF OPTION. The term of each Option shall be stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of grant thereof. In the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant or such shorter term as may be provided in the
Option Agreement.

     8. OPTION EXERCISE PRICE AND CONSIDERATION.

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

               (i)   In the case of an Incentive Stock Option

                    (A) granted to an Employee who, at the time of grant of such
Option, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the exercise
price shall be no less than 110% of the Fair Market Value per Share on the date
of grant.

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

                                        5
<PAGE>

               (ii)  In the case of a Nonstatutory Stock Option

                    (A) granted to Service Provider who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or
Subsidiary, the exercise price shall be no less than 110% of the Fair Market
Value per Share on the date of grant.

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

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

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

     9. EXERCISE OF OPTION.

          (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option
granted hereunder shall be exercisable according to the terms hereof at such
times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder to Officers and Directors shall be
tolled during any unpaid leave of absence. An Option may not be exercised for
a fraction of a Share.

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

                                       6

<PAGE>

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.

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

          (b) TERMINATION OF RELATIONSHIP AS A SERVICE PROVIDER. If an Optionee
ceases to be a Service Provider, such Optionee may exercise his or her Option
within such period of time as is specified in the Option Agreement (of at least
thirty (30) days) to the extent that the Option is vested on the date of
termination (but in no event later than the expiration of the term of the Option
as set forth in the Option Agreement). In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for 90 days 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.

         In the event an Optionee ceases to be an Employee but remains
a Service Provider, such Employee's Incentive Stock Option shall automatically
convert to a Nonstatutory Stock Option on the date 91 days following such change
of status.

          (c) DISABILITY OF OPTIONEE. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise
his or her Option within such period of time as is specified in the Option
Agreement (of at least 180 days) 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
to the extent the Option is vested on the date of termination for 365 days
following the Optionee's termination. If, on the date of termination, the
Optionee is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

          (d) DEATH OF OPTIONEE. If an Optionee dies while a Service Provider,
the Option may be exercised within such period of time as is specified in the
Option Agreement (of at least 180 days) to the extent that the Option is
vested on the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Option Agreement) by the Optionee's
estate or by a person who acquires the right to exercise the Option by
bequest or inheritance. In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable to the extent the Option is
vested on the date of termination for 365 days following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to the
entire Option, the Shares covered by the unvested portion of the Option shall
immediately revert to the Plan. If the Option is not so exercised within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

                                       7

<PAGE>

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

     10. NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. The Options
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

     11. STOCK PURCHASE RIGHTS.

          (a) RIGHTS TO PURCHASE. Stock Purchase Rights may be issued either
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically of the terms, conditions and restrictions
related to the offer, including the number of Shares that such person shall be
entitled to purchase, the price to be paid, and the time within which such
person must accept such offer. The offer shall be accepted by execution of a
Restricted Stock purchase agreement in the form determined by the Administrator.

          (b) REPURCHASE OPTION. Unless the Administrator determines otherwise,
the Restricted Stock purchase agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine.

          (c) OTHER PROVISIONS. The Restricted Stock purchase agreement shall
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

          (d) RIGHTS AS A STOCKHOLDER. Once the Stock Purchase Right is
exercised, the purchaser shall have rights equivalent to those of a stockholder
and shall be a stockholder when his or her purchase is entered upon the records
of the duly authorized transfer agent of the Company. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the Stock Purchase Right is exercised, except as provided in Section 12 of
the Plan.

     12. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR ASSET SALE.

          (a) CHANGES IN CAPITALIZATION. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the plan upon cancellation or expiration of an Option or

                                       8

<PAGE>

Stock Purchase Right, as well as the price per share of Common Stock covered by
each such outstanding Option of Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into share of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an Option or Stock Purchase Right.

          (b) DISSOLUTION OR LIQUIDATION. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option or Stock Purchase Right until
fifteen (15) days prior to such transaction as to all of the Optioned Stock
covered thereby, including Shares as to which the Option or Stock Purchase Right
would not otherwise be exercisable. In addition, the Administrator may provide
that any Company repurchase option applicable to any Shares purchased upon
exercise of an Option or Stock Purchase Right shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option or Stock Purchase Right will terminate immediately prior to the
consummation of such proposed action.

          (c) MERGER OR ASSET SALE. In the event of a merger of the Company with
or into another corporation which does not constitute a "Change of Control" (as
defined in Section 13), or the sale of substantially all of the assets of the
Company, each outstanding Option and Stock Purchase Right shall be assumed or an
equivalent option or right substituted by the successor corporation or a Parent
or Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option or Stock Purchase
Right, the Optionee shall fully vest in and have the right to exercise the
Option or Stock Purchase Right as to all of the Optioned Stock, including Shares
as to which it would not otherwise be vested or exercisable. If an Option or
Stock Purchase Right becomes fully vested and exercisable in lieu of assumption
or substitution in the event of a merger or sale of assets, the Administrator
shall notify the Optionee in writing or electronically that the Option or Stock
Purchase Right shall be fully exercisable for a period of fifteen (15) days from
the date of such notice, and the Option or Stock Purchase Right shall terminate
upon the expiration of such period. For the purposes of this paragraph, the
Option or Stock Purchase Right shall be considered assumed if, following the
merger or sale of assets, the option or right confers the right to purchase or
receive, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right immediately prior to the merger or sale of assets, the
consideration (whether stock, cash, or other securities or property) received in
the merger or sale of assets by holders of Common Stock for each Share held on
the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding Shares); provided,

                                       9

<PAGE>

however, that if such consideration received in the merger or sale of assets is
not solely common stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

     13. VESTING ACCELERATION ON CHANGE OF CONTROL.

          (a) VESTING ACCELERATION. In the event of a "Change of Control,"
(i) all of the Optionee's rights to purchase stock under all stock option
agreements with the Company pursuant to the Plan shall be automatically vested
in their entirety on an accelerated basis and be fully exercisable, and (ii) all
of the Company's rights to repurchase unvested stock under all restricted stock
purchase agreements pursuant to the Plan with the Optionee shall lapse in their
entirety on an accelerated basis:

               (i)   as of the date immediately preceding such "Change of
Control" in the event any such stock option agreement or restricted stock
purchase agreement is or will be terminated or cancel (except by mutual consent)
or any successor to the Company fails to assume and agree to perform the
Company's obligations under all such stock option agreements and restricted
stock purchase agreements; or

               (ii)  as of the date immediately preceding such "Change of
Control" in the event the Optionee does not or will not receive upon exercise of
the Optionee's stock purchase rights under any such stock option agreement or in
exchange for the Optionee's restricted stock acquired pursuant to any such
restricted stock purchase agreement the same identical securities and/or other
consideration as is received by all other stockholders in any merger,
consolidation, sale, exchange or similar transaction occurring upon or after
such "Change of Control"; or

               (iii) as of the date immediately preceding any "Involuntary

the purposes of this Section 13(d), no act or failure to act shall be considered
"willful" unless

                                       11

act or omission was in or not opposed to the best interests of the Company.

continuous status as an employee of the Company terminates by reason of the
Optionee's voluntary resignation (and not Involuntary Termination) or if the
Optionee's continuous status as an employee of the Company in terminated for

Option, the Administrator may require the person exercising such Option to

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.

whose duties in connection with the Company assure their access to equivalent
information.

         to have a Fair Market Value on the date of surrender or attestation
         equal to the aggregate exercise price of the Shares as to which such

         (i) Appropriate adjustments in the number of Shares and the exercise
         price subject to each outstanding option shall be made by the
         Administrator to give effect to the number of Shares of the Company

         ensuring that the rights of Optionees are not prejudiced thereby
         (including amalgamations, mergers, reorganizations, liquidations and
         similar material transactions), subject to the approval, if required of

         Option and of the exercisability or vesting of the Option. All
         determinations of the Board under this paragraph (ii) (including a

Dear Greg:

                  RE: AMENDED AND RESTATED EMPLOYMENT AGREEMENT

In consideration of the premises and mutual covenants contained herein and for
other good and valuable consideration, the full receipt and sufficiency of which
is hereby acknowledged, it is agreed as follows:

AMENDMENT TO ORIGINAL AGREEMENT. This agreement (referred to herein as the
"Agreement") amends, confirms and restates the terms of your original employment
agreement with 724 dated April 13, 1998 ("Commencement Date"), pursuant to which
724 agreed to employ you as Chairman and Chief Executive Officer and pursuant to
which you accepted such employment.

DUTIES.  So long as you are employed by 724:

(a)  you will devote your full time and energy to the business and affairs of
     724, well and faithfully serve 724, and use your best efforts, skills and
     abilities to promote the interests of 724;

(b)  you will be Chairman of the Board of Directors and Chief Executive Officer
     of 724 and shall report to the Board of Directors in accordance with the
     provisions, relating to your employment as such, of the unanimous
     shareholders' agreement between 724 and its shareholders dated August 2,
     1999 (the "Shareholders' Agreement").

(c)  you will abide by any 724 policies that the Board of Directors of 724 may
     establish or amend having general application to 724's staff and
     management; and

(d)  you acknowledge that the hours of work involved will vary and be irregular
     and are those hours required to meet the objectives of 724 and you
     acknowledge that this paragraph constitutes an agreement to work such hours
     where such agreement is required by applicable legislation.

COMPENSATION AND BENEFITS. Your compensation and benefits are listed in Schedule
"A" attached hereto and forming part of this agreement. For greater certainty,
the monthly salary set out in Schedule "A" represents a 5% increase from the
annual salary payable to you prior to the date hereof. Your compensation will be
payable bi-weekly and will be subject to such periodic review as may be deemed
appropriate by 724 from time to time.
<PAGE>

OWNERSHIP OF WORK. You expressly acknowledge that 724 shall have all proprietary
rights and intellectual property interests, including, without limitation, all
patent rights, trademark rights, copyrights, mask work rights, moral rights,
throughout the world (collectively, "Proprietary Rights") in connection with any
Proprietary Information (as defined below) of 724.

"Proprietary Information" means all information and/or technology that you
conceive of, create, discover, invent or develop (solely or jointly with others,
whether or not such others are employees or consultants of 724), during your
employment by 724 and as part of the service that you provide to 724 hereunder,
if it:

(a)  relates in any manner to the actual business, research or development of
     724 (or its subsidiaries, affiliates, partnerships and joint ventures); or

(b)  relates in any manner to the reasonably anticipated business, research or
     development of 724 (or its subsidiaries, affiliates, partnerships and joint
     ventures); or

(c)  is suggested by or results from matters with which you are aware as a
     result of your employment with 724; or

(d)  is suggested by or results from any task assigned to you or work performed
     by you for or on behalf of 724 (or its subsidiaries, affiliates,
     partnerships and joint ventures);

For greater certainty, Proprietary Rights include all proprietary rights and
intellectual property interests in any modifications, enhancements, and
improvements made to Proprietary Information which are conceived of, created,
discovered, invented or developed by you and which are subject to the
Pre-existing Proprietary Rights (as such term is defined below).

By way of example and without limitation, Proprietary Information includes (I)
discoveries, inventions (whether patentable or not), mask works, trade secrets,
algorithms, ideas, designs, techniques, processes or methods, formulas, and
other know-how, and (ii) works of authoriship (whether published or

applications, development tools, source code, object code, data programs, and
other software, creative works, writings, drawings, designs, photographic or
other renderings.

You hereby assign fully to 724 any and all rights, title and interest that you
may have in the Proprietary Information to date or will later do so, whether or
not such Proprietary Information is capable of intellectual property protection,
and agree to sign appropriate documentation as requested by 724 to confirm such
ownership. You also agree, in connection with any Proprietary Information, to
promptly disclose them to 724 or its designee as appropriate, promptly execute a
specific assignment of title to 724 or its designee, and do anything else
reasonably necessary to enable 724 or its designee to secure patent, copyright
or other forms of protection for the Proprietary Information in Canada, the
United States, and in all other countries, at 724's expense. To that end you
will execute, verify, and deliver such documents and perform such other acts
(including appearances as a witness) as 724 may reasonably request in connection
with applying for, obtaining, perfecting, evidencing, sustaining, and enforcing
such Proprietary Rights and the assignment thereof.
<PAGE>

In addition, you will execute, verify, and deliver assignments of such
Proprietary Rights to 724 or its designee when requested. Your obligation to
assist 74 with respect to Proprietary Rights relating to Proprietary Information
in any and all countries shall continue beyond the termination of your
employment by 724, but 724 shall compensate you at a reasonable rate, after your
termination for the time actually spent by you at 724's request on such
assistance. In the event that 724 is unable for any reason, after reasonable
effort, to secure from you your signature on any document needed in connection
with the actions specified in this paragraph, you hereby irrevocably designate
and appoint 724 and its duly authorized officers and agents as your agent and
attorney in fact, to act for and, in your behalf, to execute, verify and file
any such documents and to do all other lawfully permitted acts to further the
purposes of this Agreement with the same legal force and effect as if executed
by you.

Without limitation, all working papers, notes and memoranda or other
manifestations of confidential data which are made or obtained by you during the
term of your employment relating to the business of 724 shall be the property of
724 and will accordingly be provided to 724 upon termination of your employment.

ASSIGNMENT OF ADDITIONAL PROPRIETARY RIGHTS. You acknowledge and confirm that
the terms and conditions of this Agreement concerning Proprietary Information
(as defined herein) and the ownership of Proprietary Rights therein (as defined
herein) are in substance the same as those terms and conditions which have
governed your employment since you started with 724. For greater certainty, you
specifically acknowledge and confirm that the paragraphs entitled "Ownership of
Work", "Waiver of Moral Rights", "Confidential Data and Non-Disclosure" and
"Pre-existing Proprietary Rights" of this Agreement are intended to apply to the
entire period of your employment with 724.

You acknowledge that the Proprietary Information and Proprietary Rights therein
created within the scope of your employment with 724, since the Commencement
Date of your employment, belong to 724 by operation of law, whether they were
created before or after the date of this Agreement. You acknowledge and confirm
that your assignment of all Proprietary Right in the Proprietary Information as
provided in the paragraph entitled "Ownership of Work", extends to all of such
Proprietary Rights, whether acquired or developed before or after the date of
this Agreement.

WAIVER OF MORAL RIGHTS. You hereby expressly and irrevocably waive any and all
moral rights arising under copyright law that you, as author, may have with
respect to any copyrighted works prepared by you for 724 in the course of your
employment and you agree that 724 (and its subsidiaries, affiliates,
partnerships, joint ventures, direct and indirect licensees) may modify, adapt,
translate and use such works as it sees fit, provided however that if such work
is so altered, you retain the right to not have your name associated with such
alterations. You also expressly waive any right that you may have as author of a
work of authorship to include your name in any Proprietary Information that is a
work of authorship when such work is distributed publicly or otherwise.

present and future developments, sales literature and brochures, form documents,
computer files, customer lists, customer and supplier relationships, corporate
and financial information, marketing or sales strategies, and other information

"confidential data") to which you may have access as a result of your employment
by 724. You acknowledge that such confidential data is the property of 724 (and
its subsidiaries, affiliates, partnerships and joint ventures), and third
parties from which 724 has acquired confidential data, and agree that, during
the term of your employment and any time thereafter, you will not, directly or
indirectly, in any manner or for any reason whatsoever (other than in the
ordinary and usual course of 724's (and its subsidiaries, affiliates,
partnerships and joint ventures) business and for its benefit), disclose to any
person, firm or corporation any of the confidential data or use any of the

     (ii)  is rightfully obtained by you from a third party;

     (iii) is disclosed with the written consent of the party whose information
           it is; or

     (iv)  is disclosed pursuant to court order, other legal compulsion or
           required by law.

On termination of your employment or upon demand by 724, you agree to return to
724 (and its subsidiaries, affiliates, partnerships and joint ventures) all
confidential data embodied or recorded in tangible form which is in your
possession or control, including without limitation, all, working papers, notes
and memoranda which are made or obtained by you during the term of your
employment relating to the business of 724. Your obligation under this section
will continue if your employment with 724 terminates for any reason.

You also agree not to disclose to 724 (and its subsidiaries, affiliates,
partnerships and joint ventures), use in its business or cause it to use any
information that is confidential to others. For greater certainty, You agree to
not, at any time, disclose to, or discuss with, 724 (and its subsidiaries,
affiliates, partnerships and joint ventures) employees any confidential or
proprietary data belonging to your former employers.

PRE-EXISTING PROPRIETARY RIGHTS. Proprietary Rights, if any, including without
limitation inventions, if any, whether patented or unpatented, which you
conceived, created, or developed, of which became known to you prior to the
commencement of your employment relationship with 724 ("Pre-existing Proprietary
Rights") are excluded from the scope of this Agreement. For greater certainty,
to your best knowledge, the Pre-existing Proprietary Rights referred to in this
paragraph includes, without limitation, the Proprietary Information listed in
Schedule "B" attached hereto.

NON-COMPETITION AND NON-SOLICITATION. You recognize that in performing the
duties of your employment, you will occupy a position of trust and confidence,
giving you knowledge with respect to many aspects of the business carried on by
724 (and its subsidiaries, affiliates, partnerships and joint ventures). Such
knowledge shall be used solely in furtherance of the business interests of 724
(and its subsidiaries, affiliates, partnerships and joint ventures) and not in
any manner which would be detrimental to it. You agree that so long as you are
employed by
<PAGE>

724 and for one (1) year thereafter, unless you obtain the prior written consent
of 724, you shall not directly or indirectly, in any manner or capacity
whatsoever.

(a)  carry on or be engaged in or hold any interest in or advise, manage or
     assist in (e.g. act as an officer, director, employee, independent
     contractor, partner, consultant, advisor, agent proprietor, trustee or
     investor) any business enterprise (e.g. division, subsidiary or business
     unit) of any entity in any country of the world where 724 does business or
     proposes to do business which offers or, based on your knowledge or
     information that is publicly available, proposes to offer any goods or
     services which directly competes with the goods or services offered or,
     based on your best knowledge, proposed to be offered by 724 (and its
     subsidiaries, affiliates, partnerships and joint ventures) as of the date
     on which your employment terminates ("Competitive Business"); or

(b)  solicit or enter into any form of business arrangement with any person who
     was or is proposed to be a client or business partner of 724 (and its
     subsidiaries, affiliates, partnerships and joint ventures) at the date that
     your employment terminates, or during the prior one (1) year period, if
     such business arrangement or proposed business arrangement is in respect of
     a Competitive Business;

provided, however, that nothing in this paragraph shall prevent you from owning
up to 5% of the voting stock of any entity.

724 hereby expressly acknowledges that you are involved as an investor, advisor,
member of the board of directors, or in some other capacity with the following
companies: (i) Bayshore Capital; (ii) RPM Technologies; (iii) iMoney; (iv) Blue
Sky Capital Corporation; (v) 1319079 Ontario Inc.; (vi) Delano Technology Corp.;
(vii) Orchard Capital. 724 consents to your involvement with such companies,
provided that you comply with your obligations of confidentiality to 724 in
accordance with the terms of this Agreement, and further provided that to the
extent that any such company is involved in or stands to be involved in a
Competitive Business, you agree not to exert any day-to-day management control
over such company.

If the provisions of this section are ever adjudicated to exceed the limitations
on time or geographic scope permitted by applicable law, then such provisions
shall be deemed reformed to the maximum time or geographic scope permitted by
applicable law.

EMPLOYEES. You agree that during the term of your employment and for one (1)
year thereafter, you will not, directly or indirectly, or assist others to,
recruit, solicit or endeavour to entice away from 724 (or its subsidiaries,
affiliates, partnerships and joint ventures) any individual who was or becomes
an employee of or service provider to 724 (or its subsidiaries, affiliates,
partnerships and joint ventures) at any time within the one (1) year period
before or after termination of your employment.

COVENANTS REASONABLE AND INJUNCTION. You acknowledge that (a) the covenants
contained in the paragraphs entitled "Confidential Data and Non-Disclosure",
"Non-Competition and Non-Solicitation" and "Employees" are essential elements to
this Agreement and that, but for your agreement to enter into such covenants,
724 would not have entered into this Agreement with you; and (b) since your
breach of any of such provisions would cause serious and irreparable
<PAGE>

harm to 724 which could not adequately be compensated for in damages, and in the
event of a breach by you of any of such provisions, you acknowledge that an
injunction may be issued against you restraining you from any further breach of
any such provision. The provisions of this paragraph shall not be construed so
as to be derogation of any other remedy which 724 may have in the event of such
a breach.

The existence of any claim or cause of action that you may have against 724
(or its subsidiaries, affiliates, partnerships and Joint ventures), whether
pursuant to this Agreement or otherwise, shall not constitute a defence to the
enforcement by 724 of the provisions of this paragraph or the paragraphs
entitled "Confidential Data and Non-Disclosure", "Non-Competition and
Non-Solicitation" and "Employees".

NON-DISPARAGEMENT. You agree that you shall not, during the term of your
employment with 724 and for one year thereafter, in any communications with any
customer or client of 724, or any of its affiliates, criticize, ridicule or make
any statement which disparages or is derogatory of 724, or any of its
affiliates, or any of their officers, directors, agents or employees.

NO CONFLICTING OBLIGATION. You represent and covenant that your entry into and
performance of all the terms of this Agreement and of your responsibilities as
an employee of 724 does not and will not breach any confidentiality, secrecy or
other agreement or obligation, whether written or oral, that you have with or to
any third party.

TERMINATION.  Your employment may be terminated by 724:

(a)  without compensation if you, by reason of physical or mental disability,
     are unable to fulfill your obligations and duties hereunder on a full time
     basis (other than by reason of authorized vacation or leave) for a period
     in excess of 40 working days in any 4 month period;

(b)  without compensation, for cause, which shall include, without limitation:

     (i)   any willful and continuing failure by you to observe and perform any
           of your covenants and obligations hereunder,

     (ii)  fraud, dishonesty, gross negligence or willful malfeasance by you in
           connection with the performance of your duties hereunder; or

     (iii) any abuse of alcohol or drugs by you which adversely affects your
           ability to perform your duties hereunder; or

(c)  without cause at any time upon giving you notice or payment in lieu of
     notice and severance, as required by any statutory and common law
     requirement applying to your employment with 724, and as provided in this
     Agreement, payable on your delivery of a release to the Board of Directors
     of 724.

The parties acknowledge and confirm that, notwithstanding the section entitled
"Entire Agreement", nothing in this Agreement is intended nor shall be
interpreted to interfere in any way with any provision of the Shareholders'
Agreement that relates to your employment or the
<PAGE>

termination thereof, and 724 shall not take any action pursuant to this
Agreement that would conflict with, or cause a breach by 724 of, any provision
of the Shareholders' Agreement relating thereto.

COMPENSATION ON TERMINATION FOR DISABILITY. During any period that you fail to
perform your duties hereunder as a result of disability due to physical or
mental illness, you shall continue to receive the salary payable to you until
your employment is terminated pursuant to subparagraph (a) in the paragraph
entitled "Termination", provided that payments so made to you shall be reduced
by the sum of the amounts, if any, payable to you, under any disability benefit
plans of 724 or under any governmental disability insurance programmes or other
plans in which you are a participant or pursuant to which you are entitled to
receive benefits.

COMPENSATION ON TERMINATION FOR CAUSE. If your employment is terminated for
cause, 724 shall pay you your salary and benefits through the date of
termination and 724 shall have no further obligations to you under this
Agreement or in connection with your employment by 724.

NOTICES. Any notice which may or is required to be given pursuant to this
Agreement shall be in writing and shall be sufficiently given or made if mailed
by prepaid registered mail, faxed or served personally upon the party for whom
it is intended, addressed to the other party at the address or fax number first
above written. The date of receipt of any notice, if served personally or by
fax, shall be deemed to be the date of delivery thereof and, if mailed, the
third business day after delivery.

ASSIGNMENT. You acknowledge that 724 may assign this Agreement and the benefits
of your covenants and obligations under this Agreement to any person who
purchases all or substantially all the assets of 724. In addition, this
Agreement and the rights and obligations of 724 may be assigned at any time by
724 to an affiliate of 724. Subject to the foregoing, neither this Agreement nor
any rights or obligations hereunder shall be assignable by any party without the
prior written consent of the other party. Subject thereto, this Agreement shall
enure to the benefit of and be binding upon the parties and their respective
heirs, executors, administrators, legal personal representatives, successors
(including any successor by reason of amalgamation or statutory arrangement of
any party) and permitted assigns.

INVALIDITY AND SEVERABILITY. If a court of competent jurisdiction would
otherwise adjudge, declare or decree all or any portion of the covenants set
forth in this Agreement void or unenforceable in the circumstances, the portions
thereof which would otherwise be held void or unenforceable shall, automatically
and without further act on the part of either of us, but only as regards those
matters or parties before the court, be reduced in scope, territory or duration
of time to such an extent that such court would hold the same to be enforceable
in the circumstances before the court, or alternatively, that provision shall be
deemed to be severed herefrom, and the remaining provisions of this Agreement
shall not be affected thereby and shall remain valid and enforceable.

FURTHER ASSURANCES. You agree to do such acts and execute such further
documents, conveyances, deeds, assignments, transfers and the like, and will
cause the doing of such acts and will cause the execution of such further
documents as are within your power as 724 may in
<PAGE>

writing at any time and from time to time reasonably request be done and or
executed, in order to give full effect to the provisions of this Agreement.

WAIVER OF RIGHTS. Any waiver of, or consent to depart from, the requirements of
any provision of this Agreement shall be effective only if it is in writing and
signed by the party giving it, and only in the specific instance and for the
specific purpose for which it has been given. No failure on the party of any
party to exercise, and no delay in exercising, any right under this Agreement
shall operate as a waiver of such right. No single or partial exercise of any
such right shall preclude any other or further exercise of such right or the
exercise of any other right.
