                                    ARTICLE I
                             THE PLAN OF ARRANGEMENT

         1.1 IMPLEMENTATION STEPS BY COMPANY. Company and Amalgamation Sub each
covenants in favor of Parent that Company shall, or shall cause Amalgamation Sub
to:

                  (a) as soon as reasonably practicable, apply in a manner
acceptable to Parent under Section 182 of the OBCA for an order approving the
Arrangement and for the Interim Order, and thereafter proceed with and
diligently pursue the obtaining of the Interim Order;

                  (b) convene and hold the Company Shareholders Meeting (as
defined in Section 2.13) for the purpose of considering the Arrangement
Resolution and the Continuance Resolution (and for any other proper purpose as
may be set out in the notice for such meeting);

                  (c) subject to obtaining such shareholder approval as is
required by the CBCA, the OBCA and the Interim Order, proceed with and
diligently pursue the Continuance, send to the Director under the CBCA, for
endorsement and filing by such Director, the Articles of Continuance under the
OBCA and, obtain a certification of continuance, and diligently pursue the
application to the Court for the Final Order; and

                  (d) subject to obtaining the Final Order and the satisfaction
or waiver of the other conditions herein contained in favor of each party, send
to the Director Articles of Arrangement and such other documents as may be
required in connection therewith under the OBCA to give effect to the
Arrangement.

         1.2 INTERIM ORDER. The notice of motion for the application referred to
in Section 1.1(a) shall request that the Interim Order provide:

                  (a) for the class of persons to whom notice is to be provided
in respect of the Arrangement and the Company Shareholders Meeting and for the
manner in which such notice is to be provided:


                                       -2-
<PAGE>
                  (b) that the requisite shareholder approval for the
Arrangement Resolution shall be 66-2/3% of the votes cast on the Arrangement
Resolution by holders of Company Common Shares present in person or by proxy at
the Company Shareholders Meeting;

                  (c) that, in all other respects, the terms, restrictions and
conditions of the by-laws and articles of Company, including quorum requirements
and all other matters, shall apply in respect of the Company Shareholders
Meeting; and

                  (d) for the grant of the Dissenters' Rights.

         1.3 EFFECT OF THE ARRANGEMENT. At the Effective Time, the effect of the
Arrangement shall be as provided in this Agreement and the Plan of Arrangement
and the applicable provisions of the OBCA. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time all the property,
rights, privileges, powers and franchises of Company will continue to repose in
Company, and all debts, liabilities and duties of Company will continue as the
debts, liabilities and duties of Company.

         1.4 EFFECT ON CAPITAL STOCK. Subject to the terms and conditions of
this Agreement, at the Effective Time, by virtue of the Arrangement, the
following shall occur:

                  (a) EXCHANGE OF COMPANY COMMON SHARES. Each outstanding
capital share of the Company (each a "COMPANY COMMON SHARE" and collectively,
the "COMPANY COMMON SHARES") issued and outstanding immediately prior to the
Effective Time, other than any Company Common Shares to be canceled pursuant
to Section 1.6(b) and any Dissenting Shares (as defined in and to the extent
provided in Section 1.5(a)), will, after giving effect to the Amalgamation,
be automatically exchanged (subject to Section 1.4(e)) with Canadian Sub for
0.165017 shares of Common Stock, $0.001 par value per share, of Parent (the
"PARENT COMMON STOCK") (the "EXCHANGE RATIO") (which reflects the two-for-one
stock split effected as a stock dividend to be paid by Parent (the "STOCK
SPLIT") on February 18, 2000) upon surrender of the certificate representing
such Company Common Share in the manner provided in Section 1.6 (or in the
case of a lost, stolen or destroyed certificate, upon delivery of an
affidavit (and bond, if required) in the manner provided in Section 1.8). In
no event will Parent be required to issue more than 2,563,273 shares of
Parent Common Stock in connection with the Arrangement, inclusive of shares
of Parent Common Stock issuable in connection with the assumption of
warrants, options or other rights to acquire Company Common Shares as
required by this Agreement. If any Company Common Shares outstanding
immediately prior to the Effective Time are unvested or are subject to a
repurchase option, risk of forfeiture or other condition under any applicable
restricted shares purchase agreement or other agreement with Company, then
the shares of Parent Common Stock issued in exchange for such Company Common
Shares will also be unvested and subject to the same repurchase option, risk
of forfeiture or other condition, and the certificates representing such
shares of Parent Common Stock may accordingly be marked with appropriate
legends. Company shall take all action that may be necessary to ensure that,
from and after the Effective Time, Parent is entitled to exercise any such
repurchase option or other right set forth in any such restricted shares
purchase agreement or other

                                       -3-
<PAGE>

agreement. Where used herein, the term "COMPANY COMMON SHARES" shall, if the
context so requires, refer to common shares of Amalco.

                  (b) CANCELLATION OF PARENT-OWNED STOCK. Each Company Common
Share held by Company, Parent or any direct or indirect wholly-owned subsidiary
of Company or of Parent immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof.

                  (c) STOCK OPTIONS. At the Effective Time, all options to
purchase Company Common Shares then outstanding under Company's Management's
Stock Option Plan and the management stock option agreements referred to in
Section 2.3(a) of the Company Schedule (collectively, the "COMPANY OPTION
PLANS") shall be assumed by Parent in accordance with Section 6.6 hereof.

                  (d) ADJUSTMENTS TO EXCHANGE RATIO. The Exchange Ratio shall be
adjusted to reflect appropriately the effect of any stock split, reverse stock
split, stock dividend (including any dividend or distribution of securities
convertible into Parent Common Stock or Company Common Shares), extraordinary
cash dividends, reorganization, recapitalization, reclassification, combination,
exchange of shares or other like change with respect to Parent Common Stock or
Company Common Shares occurring on or after the date hereof and prior to the
Effective Time. Notwithstanding the foregoing, no adjustment to the Exchange
Ratio shall be made in connection with the Stock Split to be paid February 18,
2000.

                  (e) FRACTIONAL SHARES. No fraction of a share of Parent Common
Stock will be issued by virtue of the Arrangement, but in lieu thereof each
holder of Company Common Shares who would otherwise be entitled to a fraction of
a share of Parent Common Stock (after aggregating all fractional shares of
Parent Common Stock that otherwise would be received by such holder) shall, upon
surrender of such holder's Certificates(s) (as defined in Section 1.6(c))
receive from Parent an amount of cash (rounded to the nearest whole cent),
without interest, equal to the product of (i) such fraction, multiplied by (ii)
the closing price of one share of Parent Common Stock for the five (5) most
recent days that Parent Common Stock has traded ending on the trading day
immediately prior to the Effective Time, as reported on the Nasdaq National
Market ("NASDAQ").

         1.5 DISSENTING SHARES.

                  (a) Notwithstanding any provision of this Agreement to the
contrary, the shares of any holder of Company Common Shares who has demanded and
perfected appraisal and dissent rights ("DISSENTERS' RIGHTS") for such shares in
accordance with the Interim Order, the CBCA, or the OBCA and who, as of the
Effective Time, has not effectively withdrawn or lost such appraisal rights
("DISSENTING SHARES"), shall not be converted into or represent a right to
receive Parent Common Stock pursuant to Section 1.6, but the holder thereof
shall only be entitled to such rights as are granted by the Interim Order, the
CBCA, or the OBCA, as the case may be.


                                       -4-
<PAGE>

                  (b) Notwithstanding the provisions of subsection (a), if any
holder of Company Common Shares who demands appraisal of such shares under the
CBCA or the OBCA shall effectively withdraw (or otherwise by law not be entitled
to) the right to appraisal, then, as of the later of the Effective Time and the
occurrence of such event, such holder's shares shall automatically be converted
into and represent only the right to receive Parent Common Stock, without
interest thereon, upon surrender of the certificate representing such shares.

                  (c) Company shall give Parent (i) prompt notice of any written
demands for appraisal of any Company Common Shares, withdrawals of such demands,
and any other instruments served pursuant to the CBCA or the OBCA and received
by Company which relate to any such demand for appraisal and (ii) the
opportunity to participate in all negotiations and proceedings which take place
prior to the Effective Time with respect to demands for appraisal under the CBCA
or the OBCA. Company shall not, except with the prior written consent of Parent,
voluntarily make any payment with respect to any demands for appraisal of
Company Common Shares or offer to settle or settle any such demands.

         1.6 SURRENDER OF CERTIFICATES.

                  (a) EXCHANGE AGENT. Parent shall select a bank or trust
company reasonably acceptable to Company to act as the exchange agent (the
"EXCHANGE AGENT") in the Arrangement.

                  (b) PARENT TO PROVIDE COMMON SHARES. Promptly after the
Effective Time, Parent shall cause Canadian Sub to make available to the
Exchange Agent, for exchange in accordance with this Article I, the shares of
Parent Common Stock issuable pursuant to Section 1.4 in exchange for outstanding
Company Common Shares, and cash in an amount sufficient for payment in lieu of
fractional shares pursuant to Section 1.4(e) and any dividends or distributions
to which holders of Company Common Shares may be entitled pursuant to Section
1.4(d).

                  (c) EXCHANGE PROCEDURES. Promptly after the Effective Time,
Parent shall cause the Exchange Agent to mail to each holder of record (as of
the Effective Time) of a certificate or certificates (the "CERTIFICATES"), which
immediately prior to the Effective Time represented outstanding Company Common
Shares whose shares were exchanged for shares of Parent Common Stock pursuant to
Section 1.4, cash in lieu of any fractional shares pursuant to Section 1.4(e)
and any dividends or other distributions pursuant to Section 1.4(d), subject to
receipt of (i) a duly completed and validly executed letter of transmittal in
customary form (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall contain such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates representing shares
of Parent Common Stock, cash in lieu of any fractional shares pursuant to
Section 1.4(e) and any dividends or other distributions pursuant to Section
1.4(d). Upon surrender of Certificates for cancellation to the Exchange Agent or
to such other agent or agents as may be appointed by Parent, together with such
letter of transmittal, duly completed and validly executed in accordance with
the instructions thereto, the holders of such Certificates shall be entitled


                                       -5-
<PAGE>

to receive in exchange therefor certificates representing the number of whole
shares of Parent Common Stock into which their Company Common Shares were
exchanged at the Effective Time, payment in lieu of fractional shares which
such holders have the right to receive pursuant to Section 1.4(e) and any
dividends or distributions payable pursuant to Section 1.4(d), and the
Certificates so surrendered shall forthwith be canceled. Until so
surrendered, outstanding Certificates will be deemed from and after the
Effective Time, for all corporate purposes, subject to Section 1.4(d) as to
dividends and other distributions, to evidence only the ownership of the
number of full shares of Parent Common Stock into which such Company Common
Shares are entitled to be exchanged and the right to receive an amount in
cash in lieu of the issuance of any fractional shares in accordance with
Section 1.4(e) and any dividends or distributions payable pursuant to Section
1.4(d).

                  (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No
dividends or other distributions declared or made after the date of this
Agreement with respect to Parent Common Stock with a record date after the
Effective Time will be paid to the holders of any unsurrendered Certificates
with respect to the shares of Parent Common Stock represented thereby until the
holders of record of such Certificates shall surrender such Certificates.
Subject to applicable law, following surrender of any such Certificates, the
Exchange Agent shall deliver to the record holders thereof, without interest,
certificates representing whole shares of Parent Common Stock issued in exchange
therefor along with payment in lieu of fractional shares pursuant to Section
1.4(e) hereof and the amount of any such dividends or other distributions with a
record date after the Effective Time payable with respect to such whole shares
of Parent Common Stock.

                  (e) TRANSFERS OF OWNERSHIP. If certificates representing
shares of Parent Common Stock are to be issued in a name other than that in
which the Certificates surrendered in exchange therefor are registered, it will
be a condition of the issuance thereof that the Certificates so surrendered will
be properly endorsed and otherwise in proper form for transfer and that the
persons requesting such exchange will have paid to Parent or any agent
designated by it any transfer or other taxes required by reason of the issuance
of certificates representing shares of Parent Common Stock in any name other
than that of the registered holder of the Certificates surrendered, or
established to the satisfaction of Parent or any agent designated by it that
such tax has been paid or is not payable.

                  (f) REQUIRED WITHHOLDING. Each of the Exchange Agent, Parent
and Canadian Sub shall be entitled to deduct and withhold from any consideration
payable or otherwise deliverable pursuant to this Agreement to any holder or
former holder of Company Common Shares such amounts as may be required (as
advised by tax counsel for Parent) to be deducted or withheld therefrom under
the United States Code or under any provision of United States or Canadian
federal, state, provincial, regional, local or foreign tax law or under any
other applicable legal requirement. To the extent such amounts are so deducted
or withheld, such amounts shall be treated for all purposes under this Agreement
as having been paid to the person to whom such amounts would otherwise have been
paid.

                  (g) NO LIABILITY. Notwithstanding anything to the contrary in
this Section 1.8, neither the Exchange Agent, Parent, Canadian Sub or
Amalgamation Sub nor any party hereto shall be liable to a holder of shares of
Parent Common Stock or Company Common Shares for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

         1.7 NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON SHARES. All shares of
Parent Common Stock issued or transferred in accordance with the terms hereof
(including any cash paid in respect thereof pursuant to Section 1.4(e)) shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
Company Common Shares, and there shall be no further registration of transfers
on the records of Amalco of Company Common Shares which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to Amalgamation Sub for any reason, they shall be
canceled and exchanged as provided in this Article I.

         1.8 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Parent Common Stock into which the Company Common
Shares represented by such Certificates were converted pursuant to Section 1.4,
cash for fractional shares, if any, as may be required pursuant to Section
1.4(e) and any dividends or distributions payable pursuant to Section 1.4(d);
PROVIDED, HOWEVER, that Parent may, in its discretion and as a condition
precedent to the issuance of such certificates representing shares of Parent
Common Stock, cash and other distributions, require the owner of such lost,
stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Parent, the amalgamated corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

         1.9 TAX AND ACCOUNTING CONSEQUENCES.

business as a foreign corporation, and is in good standing, under the laws of

Agreement by Company and Amalgamation Sub and the consummation by Company and
Amalgamation Sub of the transactions contemplated hereby and thereby have been
duly and validly authorized by all necessary corporate action on the part of
Company and Amalgamation Sub and no other corporate proceedings on the part of
Company and Amalgamation Sub are necessary to authorize this Agreement, the

than the approval and adoption of this Agreement, the Continuance, and the
Arrangement by holders of not less than 66-2/3% of the outstanding Company
Common Shares in accordance with the CBCA and the OBCA, the Interim Order and
the Company Charter Documents). This Agreement and the Stock Option Agreement
have been duly and validly executed and delivered by Company and Amalgamation

this Agreement and the Stock Option Agreement by Company and Amalgamation Sub
shall not, (i) conflict with or violate the Company Charter Documents or the
equivalent organizational documents of any of Company's subsidiaries, (ii)
subject to obtaining the approval of Company's shareholders of the Continuance
and the Arrangement and compliance with the requirements set forth in Section
2.5(b) below, conflict with or violate any law, rule, regulation, order,

of time or both would become a default) under, or materially impair Company's or
any of its subsidiaries' rights or alter the rights or obligations of any third
party under, or give to others any


                                       -11-

<PAGE>

rights of termination, amendment, acceleration or cancellation of, or result
in the creation of a lien or encumbrance on any of the properties or assets
of Company or any of its subsidiaries pursuant to, any material note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise
or other instrument or obligation to which Company or any of its subsidiaries
is a party or by which Company or any of its subsidiaries or its or any of
their respective properties are bound or affected.

                  (b) The execution and delivery of this Agreement and the Stock
Option Agreement by Company and Amalgamation Sub do not, and the performance of
this Agreement by Company and Amalgamation Sub and the issuance of Company
Common Shares upon exercise of the Stock Option Agreement shall not, require any
consent, approval, authorization or permit of, or filing with or notification

SECURITIES LEGISLATION"); the filing required under the Competition Act
(Canada); the filing required with Industry Canada under the Investment Canada
Act (Canada); approval of the TSE; the Interim Order and Final Order of the
Court in respect of the Arrangement; and the pre-merger notification
requirements (the "HSR APPROVAL"), of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"); and (B) where the failure
to obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Company or, after
the Effective Time, Parent, or prevent consummation of the transactions or
otherwise prevent the parties hereto from performing their obligations under
this Agreement.

                  (c) Company, together with its affiliates, does not have
assets in Canada in aggregate value as at January 31, 1999 or January 31, 2000,
or gross revenues from sales in, from or into Canada for the year ended January
31, 1999 or January 31, 2000, that exceed in any such case $50,000,000, as

requirement by Company under the Competition Act (Canada) in connection with the

                  (a) Neither Company nor any of its subsidiaries is in conflict

any material note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which Company or
any of its subsidiaries is a party or


                                       -12-
<PAGE>

by which Company or any of its subsidiaries or its or any of their respective
properties is bound or affected, except for any conflicts, defaults or
violations that (individually or in the aggregate) would not cause the
Company to lose any material benefit or incur any material liability. No
investigation or review by any governmental or regulatory body or authority
is pending or, to the knowledge of Company, threatened against Company or its
subsidiaries, nor has any governmental or regulatory body or authority
indicated to the Company an intention to conduct the same, other than, in
each such case, those the outcome of which could not, individually or in the
aggregate, reasonably be expected to have the effect of prohibiting or
materially impairing any business practice of the Company or any of its
subsidiaries, any acquisition of material property by the Company or any of
its subsidiaries or the conduct of business by the Company or any of its
subsidiaries.

                  (b) Company and its subsidiaries hold all permits, licenses,
variances, exemptions, orders and approvals from governmental authorities which

Permits.

         2.7 ONTARIO FILINGS; FINANCIAL STATEMENTS.

                  (a) Company has made available to Parent a correct and

filed by Company with the OSC and the TSE since January 31, 1997, which are all
the forms, reports and documents required to be filed by Company with the OSC
since January 31, 1997, and, prior to the Effective Time, Company will have
furnished Parent with true and complete copies of any additional documents filed
hereafter with the OSC by Company prior to the Effective Time (all such filings,
including any financial statements or other documents, including any schedules
included therein, are referred to as the "COMPANY REGULATORY REPORTS"). Company
has not filed any confidential material change report with the OSC or any other
securities authority or regulator or any stock exchange or other self-regulatory
authority which at the date hereof remains confidential. The Company Regulatory
Reports (A) were prepared in accordance with the requirements of the Canadian
Securities Legislation, the TSE and the CBCA, as the case may be, and (B) did
not at the time they were filed (and if amended or superseded by a filing prior
to the date of this Agreement then on the date of such filing) contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading. None of
Company's subsidiaries is required to file any reports or other documents with
the OSC or the TSE.

                  (b) Each set of consolidated financial statements (including,
in each case, any related notes thereto) contained in the Company Regulatory
Reports and Company's audited consolidated financial statements as at and for
the periods ended through October 31, 1999 (copies of which have been furnished
to Parent) were prepared in accordance with Canadian generally accepted
accounting principles ("CANADIAN GAAP") applied on a consistent basis throughout
the periods involved and each fairly presents the consolidated financial
position of Company and its subsidiaries


                                       -13-
<PAGE>

at the respective dates thereof and the consolidated results of its
operations and cash flows for the periods indicated, except that the
unaudited interim financial statements were or are subject to normal
adjustments which were not or are not expected to be material in amount.

                  (c) The Company is a "reporting issuer" or its equivalent for
the purposes of the Canadian Securities Legislation and is not in violation of
any requirement thereunder.

         2.8 NO UNDISCLOSED LIABILITIES. Neither Company nor any of its
subsidiaries has any liabilities (absolute, accrued, contingent or otherwise) of
a nature required to be disclosed on a balance sheet or in the related notes to
the consolidated financial statements prepared in accordance with Canadian gaap
which are, individually or in the aggregate, material to the business, results
of operations or financial condition of Company and its subsidiaries taken as a
whole, except (i) liabilities provided for in Company's balance sheet as of
October 31, 1999 or (ii) liabilities incurred since October 31, 1999 in the
ordinary course of business, none of which is material to the business, results
of operations or financial condition of Company and its subsidiaries, taken as a
whole.

         2.9 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since October 31, 1999, there
has not been: (i) any Material Adverse Effect on Company, (ii) any declaration,
setting aside or payment of any dividend on, or other distribution (whether in
cash, shares or property) in respect of, any of Company's or any of its
subsidiaries' share capital, or any purchase, redemption or other acquisition by
Company of any of Company's share capital or any other securities of Company or
its subsidiaries or any options, warrants, calls or rights to acquire any such
shares or other securities except for repurchases from employees following their
termination pursuant to the terms of their pre-existing stock option or purchase
agreements, (iii) any split, combination or reclassification of any of Company's
or any of its subsidiaries' share capital, (iv) any granting by Company or any
of its subsidiaries of any increase in compensation or fringe benefits, except
for normal increases of cash compensation in the ordinary course of business
consistent with past practice, or any payment by Company or any of its
subsidiaries of any bonus, except for bonuses made in the ordinary course of
business consistent with past practice, or any granting by Company or any of its
subsidiaries of any increase in severance or termination pay or any entry by
Company or any of its subsidiaries into any currently effective employment,
severance, termination or indemnification agreement or any agreement the
benefits of which are contingent or the terms of which are materially altered
upon the occurrence of a transaction involving Company of the nature
contemplated hereby, (v) entry by Company or any of its subsidiaries into any
licensing or other agreement with regard to the acquisition or disposition of
any Intellectual Property (as defined in Section 2.19) other than licenses in
the ordinary course of business consistent with past practice, (vi) any material
change by Company in its accounting methods, principles or practices, except as
required by concurrent changes in Canadian gaap, or (vii) any revaluation by

                  (c) No Company Intellectual Property or Company Product is
subject to any proceeding or outstanding decree, order, judgment, contract,
license, agreement, or stipulation restricting in any material manner the use,
transfer, or licensing thereof by Company or any of its subsidiaries, or which

Property or Company Product.

                  (d) Each item of Company Registered Intellectual Property is
valid and subsisting, all necessary registration, maintenance and renewal fees
currently due in connection with such Company Registered Intellectual Property
have been made and all necessary documents, recordations and certificates in

                  (g) To the extent that any Intellectual Property has been
developed or created independently or jointly by a third party for Company or
any of its subsidiaries or is incorporated into any of the Company Intellectual
Property or any of the Company Products, Company has a written agreement with
such third party with respect thereto and Company thereby either (i) has
obtained ownership of, and is the exclusive owner of all such third party's
Intellectual Property (including the right to seek past and future damages with
respect to such Intellectual Property) in such work, material or invention by
operation of law or by valid assignment, to the fullest extent it is legally
possible to do so or (ii) has obtained a perpetual, non-terminable license
(sufficient for the conduct of its business as currently conducted and as
proposed to be conducted). Any such third party waived its moral rights in any
such Intellectual Property which has been conveyed by such third party to
Company or any of its subsidiaries.

                  (h) Neither Company nor any of its subsidiaries has
transferred ownership of, or granted any exclusive license with respect to, any
Intellectual Property that is material Company Intellectual Property used or
proposed to be used in the conduct of Company's business to any third party.
None of Company's rights in material Company Intellectual Property has lapsed or
entered the public domain.

                  (i) Section 2.19(i) of the Company Schedule lists all material
contracts, licenses and agreements to which Company or any of its subsidiaries
is a party: (i) with respect to Company Intellectual Property licensed or
transferred to any third party (other than end-user licenses in the ordinary
course which are substantially identical to Company's standard form of license
agreement attached under Section 2.19 of the Company Schedule; or (ii) pursuant
to which a third party has licensed or transferred any material Intellectual
Property to Company. Any such end-user licenses granted in the ordinary course
noted above have been only in respect of object code versions of the software
comprised in the Intellectual Property, and no third party has rights in or to
any source code comprised in the Intellectual Property.

                  (j) All contracts, licenses and agreements relating to either
(i) Company Intellectual Property or (ii) Intellectual Property of a third party
licensed to Company or any of its subsidiaries, are in full force and effect.
The consummation of the transactions contemplated by this Agreement will neither
violate nor result in the breach, modification, cancellation, termination or
suspension of such contracts, licenses and agreements. Each of Company and its
subsidiaries is in material compliance with, and has not materially breached any
term of any such contracts, licenses and agreements and, to the knowledge of
Company, all other parties to such contracts, licenses and agreements are in
compliance with, and have not materially breached any term of, such contracts,
licenses and agreements. Following the Closing Date, Company will be permitted
to exercise all of its rights under such contracts, licenses and agreements to
the same extent Company and its subsidiaries would have been able to had the
transactions contemplated by this Agreement not occurred and without the payment
of any additional amounts or consideration other than ongoing fees, royalties or
payments which Company would otherwise be required to pay. Neither this
Agreement nor the transactions contemplated by this Agreement will to Company's
knowledge, result in (i) Parent's granting to any third party any right to or
with respect to any material Intellectual


                                       -25-

<PAGE>

Property right owned by, or licensed to, it, (ii) Parent's being bound by, or
subject to, any non-compete or other material restriction on the operation or
scope of its business, or (iii) Parent's being obligated to pay any royalties
or other material amounts to any third party in excess of those payable by
Parent prior to the Closing.

                  (k) The operation of the business of Company and its
subsidiaries as such business currently is conducted, including (i) Company's
and its subsidiaries' design, development, manufacture, distribution,
reproduction, marketing or sale of the products or services of Company and its
subsidiaries (including Company Products ) and (ii) Company's use of any
product, device or process, has not, does not and, to its knowledge, will not
infringe or misappropriate the Intellectual Property of any third party or
constitute unfair competition or trade practices under the laws of any
jurisdiction or violates the rights of any person (including rights to privacy
or publicity).

                  (l) Neither Company nor any of its subsidiaries has received
notice from any third party that the operation of the business of Company or any
of its subsidiaries or any act, product or service of Company or any of its
subsidiaries, infringes or misappropriates the Intellectual Property of any
third party or constitutes unfair competition or trade practices under the laws
of any jurisdiction, or violates the rights of any person (including rights to
privacy or publicity). No Company Intellectual Property or product, technology
or service of Company or its subsidiaries is subject to any proceeding or
outstanding decree, order, judgment, agreement or stipulation that restricts in
any manner the use, transfer or licensing thereof by Company or its subsidiaries
or may affect the validity, use or enforceability of such Company Intellectual
Property.

                  (m) To the knowledge of Company, no person has or is
infringing or misappropriating any Company Intellectual Property.

                  (n) Company and each of its subsidiaries has taken reasonable
steps in accordance with normal industry practice to protect Company's and its
subsidiaries' rights in confidential information and trade secrets of the
Company or its subsidiaries that Company wishes to protect or any trade secrets
or confidential information of third parties provided to Company or any of its
subsidiaries, and, without limiting the foregoing, each of Company and its
subsidiaries has and uses its best efforts to enforce a policy requiring each
employee and contractor to execute a proprietary information/confidentiality
agreement substantially in the form provided to Parent and all current and
former employees and contractors of Company and any of its subsidiaries have
executed such an agreement, except where the failure to do so is not reasonably
expected to be material to Company. As a matter of contract or otherwise by law,
no current or former employee, consultant or contractor of Company or any
subsidiary has rights to any Company Intellectual Property and each has waived
his or her moral rights in any Company Intellectual Property.

                  (o) All of the Company Products (i) record, store, process,
calculate and present calendar dates falling on and after (and if applicable,
spans of time including) January 1, 2000, and calculate any information
dependent on or relating to such dates in the same manner, and with the same
functionality, data integrity and performance, as the Company Products recorded,
stored, processed, calculated and presented calendar dates on or before December
31, 1999, or calculated


                                       -26-
<PAGE>

any information dependent on or relating to such dates (collectively, "YEAR
2000 COMPLIANT"), and (ii) lost no functionality with respect to the
introduction of records containing dates falling on or after January 1, 2000.
All of Company's or its subsidiaries' Information Technology (as defined
below) is Year 2000 Compliant, and did not cause an interruption in the
ongoing operations of the Company's or any of its subsidiaries' business on
or after January 1, 2000. For purposes of the foregoing, the term
"INFORMATION TECHNOLOGY" shall mean and include all software, hardware,
firmware, telecommunications systems, network systems, embedded systems and
other systems, components and/or services (other than general utility
services including gas, electric, telephone and postal) that are owned or
used by Company or any of its subsidiaries in the conduct of their business,
or purchased by Company or any of its subsidiaries from third-party suppliers.

                  (p) There are neither contracts, licenses nor agreements
between either Company or any of its subsidiaries on the one hand and any other
person on the other with respect to Company Intellectual Property under which
there is any dispute known to Company or any of its subsidiaries regarding the
scope of such agreement or performance under such agreement including with
respect to any payments to be made or received by Company or any of its
subsidiaries thereunder.

                  (q) Neither Company nor any of its subsidiaries is obligated
to pay any royalties or other compensation to any person in respect of its
ownership, use or license of any of the Company Intellectual Property.

<PAGE>

the date hereof and certified by a duly authorized officer of Parent (the
"PARENT SCHEDULE"), as follows:

         3.1 ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. Each of Parent and
its subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and has the
requisite corporate power and authority to own, lease and operate its assets and
properties and to carry on its business as it is now being conducted, except
where the failure to do so would not, individually or in the aggregate, have a
Material Adverse Effect on Parent.

         3.2 AUTHORITY RELATIVE TO THIS AGREEMENT. Each of Parent and Canadian
Sub has all necessary corporate power and authority to execute and deliver this
Agreement and the Stock Option Agreement, and to perform its obligations
hereunder and thereunder and to consummate the transactions contemplated hereby
and thereby. The execution and delivery of this Agreement and the Stock Option
Agreement by Parent and Canadian Sub and the consummation by Parent and Canadian
Sub of the transactions contemplated hereby and thereby have been duly and
validly authorized by all necessary corporate action on the part of Parent and
Canadian Sub, and no other corporate proceedings on the part of Parent or
Canadian Sub are necessary to authorize this Agreement and the Stock Option
Agreement, or to consummate the transactions so contemplated. This Agreement and
the Stock Option Agreement have been duly and validly executed and delivered by
Parent and Canadian Sub and, assuming the due authorization, execution and
delivery by Company and Amalgamation Sub, constitute legal and binding
obligations of Parent and Canadian Sub, enforceable against Parent and Canadian
Sub in accordance with their respective terms. The shares of Parent Common Stock
issued at the Effective Time pursuant to the terms of this Agreement shall be

Agreement by Parent shall not, (i) conflict with or violate the Certificate of
Incorporation, Bylaws or equivalent organizational documents of Parent or any of

judgment or decree applicable to Parent or any of its subsidiaries or by which
it or their respective properties are bound or affected, or (iii) result in any
breach of or constitute a default (or an event that with notice or lapse of time
or both would become a default) under, or impair Parent's or any such
subsidiary's rights or alter the rights or obligations of any third party under,
or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or encumbrance on any of
the properties or assets of Parent or any of its subsidiaries pursuant to, any
material note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which Parent or any of

extent


                                       -30-
<PAGE>

such conflict, violation, breach, default, impairment or other effect could
not in the case of clauses (ii) or (iii) individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent.

                  (b) The execution and delivery of this Agreement by Parent and
Canadian Sub and the Stock Option Agreement by Parent do not, and the
performance of this Agreement by Parent and Canadian Sub shall not, require any
consent, approval, authorization or permit of, or filing with or notification

the United States 1933 Act; the United States 1934 Act; the securities laws of
various states within the United States and various provinces of Canada; the
pre-merger notification requirements of the HSR Act and of foreign governmental

required with Industry Canada under the Investment Canada Act (Canada); and (ii)
where the failure to obtain such consents, approvals, authorizations or permits,
or to make such filings or notifications, (x) would not prevent consummation of
the Arrangement or otherwise prevent Parent or Canadian Sub from performing
their respective obligations under this Agreement or (y) could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect on
Parent.

                  (c) Parent, together with its affiliates, does not have assets
in Canada in the aggregate as at March 31, 1999, or gross revenues from sales
in, from or into for the year ended March 31, 1999, in, from or into Canada,
that exceed in any such case $350,000,000, respectively, in aggregate value as
determined in accordance with the Notifiable Transaction Regulations promulgated
under the Competition Act (Canada). Assuming the accuracy of the representations
and warranties contained in Section 2.5(c), there is no pre-notification
requirement of Parent under the Competition Act (Canada) in connection with the
Arrangement.

         3.4 SEC FILINGS; FINANCIAL STATEMENTS.

                  (a) Parent has made available to Company a correct and
complete copy of each report, schedule, registration statement and definitive
proxy statement filed by Parent with the SEC on or after March 31, 1998 (the
"PARENT SEC REPORTS"), which are all the forms, reports and documents required
to be filed by Parent with the SEC since March 31, 1998. The Parent SEC Reports
(A) were prepared in accordance with the requirements of the United States 1933
Act or the United States 1934 Act, as the case may be, and (B) did not at the
time they were filed (or if amended or superseded by a filing prior to the date
of this Agreement, then on the date of such filing) contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. None of Parent's
subsidiaries is required to file any reports or other documents with the SEC.

                  (b) Each set of consolidated financial statements (including,
in each case, any related notes thereto) contained in the Parent SEC Reports was
prepared in accordance with U.S. gaap applied on a consistent basis throughout
the periods involved (except as may be indicated in the


                                       -31-
<PAGE>

notes thereto or, in the case of unaudited statements, do not contain
footnotes as permitted by Form 10-Q of the United States 1934 Act) and each
fairly presents in all material respects the consolidated financial position
of Parent and its subsidiaries at the respective dates thereof and the
consolidated results of its operations and cash flows for the periods
indicated, except that the unaudited interim financial statements were or are
subject to normal adjustments which were not or are not expected to be
material in amount.

                  (c) Since December 31, 1999, the date of the balance sheet
included in Parent's report on Form 10-Q filed with the SEC for the quarter
ended December 31, 1999, there has not occurred any Material Adverse Effect on
Parent.

         3.5 CIRCULAR DISCLOSURE. None of the information supplied or to be
supplied by Parent for inclusion or incorporation by reference in the Circular
will, at the dates mailed to the shareholders of Company, at the time of the
Company Shareholders Meeting and as of the Effective Time, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading. Notwithstanding the
foregoing, Parent makes no representation or warranty with respect to any
information supplied by Company which is contained in the Circular.

         3.6 ABSENCE OF LITIGATION. Except as is set forth in the Parent SEC
Reports, there are no claims, actions, suits or proceedings pending or, to the
knowledge of Parent, threatened (or, to the knowledge of Parent, any
governmental or regulatory investigation pending or threatened) against Parent
or any of its subsidiaries or any properties or rights of Parent or any of its
subsidiaries, before any court, arbitrator or administrative, governmental or
regulatory authority or body, domestic or foreign, that are required to be
disclosed in any Parent SEC Report (or as of the date hereof which would be
required to be disclosed in any Parent SEC Report to be filed).

         3.7 NO UNDISCLOSED LIABILITIES. Neither Parent nor any of its
subsidiaries has any liabilities (absolute, accrued, contingent or otherwise) of
a nature required to be disclosed on a balance sheet or in the related notes to
the consolidated financial statements prepared in accordance with U.S. gaap
which are, individually or in the aggregate, material to the business, results
of operations or financial condition of Parent and its subsidiaries taken as a
whole, except (i) liabilities provided for in Parent's balance sheet as of
December 31, 1999 or (ii) liabilities incurred since December 31, 1999 in the
ordinary course of business, none of which is material to the business, results
of operations or financial condition of Parent and its subsidiaries, taken as a
whole.

         3.8 TSB INTERNATIONAL TAX TREATMENT. In connection with Company's
participation in a stock exchange transaction in accordance with an Exchange
Agreement dated as of July 28, 1999 (the "Exchange Agreement") among Company,
TSB International, Inc. and certain shareholders of TSB International, Inc.,
Parent agrees, on behalf of itself, its subsidiaries and its affiliates, that it
will not file any tax return that reports the exchange transaction in any manner
inconsistent with the tax treatment described in the recitals of the Exchange
Agreement, unless otherwise required by the determination of the United States
Internal Revenue Service.

                          COMPANY SHAREHOLDER APPROVAL


         5.1 CIRCULAR; OTHER FILINGS; BOARD RECOMMENDATIONS.

                  (a) As promptly as practicable after the execution of this
Agreement, Company, Canadian Sub and Parent will prepare, and Company and
Amalgamation Sub will file with the Court, the Circular. Each of Parent and
Company shall provide promptly to the other such information concerning its
business and financial statements and affairs as, in the reasonable judgment of
the providing party or its counsel, may be required or appropriate for inclusion
in the Circular, or in any amendments or supplements thereto, and to cause its
counsel and auditors to cooperate with the other's counsel and auditors in the
preparation of the Circular. Each of Company, Parent, Amalgamation Sub and
Canadian Sub will afford the other parties an opportunity to review all
materials to be submitted to the Court, and shall make all such changes as are
reasonably requested. Each of Company, Amalgamation Sub, Canadian Sub and Parent
will respond to any comments of the Court, and will use its respective
commercially reasonable efforts to have the Interim Order issued as promptly as
practicable after such filing, and Company will cause the Circular to be mailed
to its shareholders at the earliest practicable time after the Interim Order has
been granted by the Court. As promptly as practicable after the date of this
Agreement, each of Company, Amalgamation Sub, Canadian Sub and Parent will
prepare and file any other filings required to be filed by it pursuant to the
requirements of the CBCA, the OBCA, the Interim Order, the Canadian Securities
Legislation, the TSE and any other Canadian, United States or other laws
relating to the Arrangement and the transactions contemplated by this Agreement
(the "OTHER FILINGS"). Each of Company, Amalgamation Sub, Canadian Sub and
Parent will notify the other promptly upon the receipt of any comments from the
Court or its staff or any other government officials and of any request by the
Court or its staff or any other government officials for


                                       -36-
<PAGE>

amendments or supplements to the Circular or any Other Filing or for
additional information and will supply the other with copies of all
correspondence between such party or any of its representatives, on the one
hand, and the Court or its staff or any other government officials, on the
other hand, with respect to the Circular, the Arrangement or any Other
Filing. Each of Company, Amalgamation Sub, Canadian Sub and Parent will cause
all documents that it is responsible for filing with the Court or other
regulatory authorities under this Section 5.1(a) to comply in all material
respects with all applicable requirements of law and the rules and
regulations promulgated thereunder. Whenever any event occurs which is
required to be set forth in an amendment or supplement to the Circular or any
Other Filing, Company, Amalgamation Sub, Canadian Sub or Parent, as the case
may be, will promptly inform the other of such occurrence and cooperate in
filing with the Court or its staff or any other government officials, and/or
mailing to shareholders of Company, such amendment or supplement.

                  (b) Subject to Section 5.2(c), the Circular will include the
unanimous recommendation of the Board of Directors of Company in favor of
approval of the Continuance and the Arrangement.

         5.2 MEETING OF COMPANY SHAREHOLDERS.

                  (a) Promptly after the date hereof, Company will take all
action pursuant to the requirements of the CBCA, the OBCA, the Interim Order,
the Canadian Securities Legislation (and all other applicable securities laws),
the TSE and the Company Charter Documents to convene the Company Shareholders
Meeting to be held as promptly as practicable, and in any event Company will use
its best efforts to convene such meeting not later than March 24, 2000, for the
purpose of voting upon the Continuance and the Arrangement. Subject to Section
5.2(c), Company will use its commercially reasonable efforts to solicit from its
shareholders proxies in favor of the approval of the Continuance and the
Arrangement and will take all other action necessary or advisable to secure the
vote or consent of its shareholders required by the rules of the TSE and the
requirements of the CBCA, the OBCA, the Interim Order, the Canadian Securities
Legislation and all other applicable securities laws to obtain such approvals.
Notwithstanding anything to the contrary contained in this Agreement, Company
may adjourn or postpone the Company Shareholders Meeting to the extent necessary
to ensure that any necessary supplement or amendment to the Circular is provided
to Company's shareholders in advance of a vote on the Continuance and the
Arrangement or, if as of the time for which the Company Shareholders Meeting is
originally scheduled (as set forth in the Circular) there are insufficient
Company Common Shares represented (either in person or by proxy) to constitute a
quorum necessary to conduct the business of the Company Shareholders Meeting.
Company shall ensure that the Company Shareholders Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited by the Company in
connection with the Company Shareholders Meeting are solicited, in compliance
with the CBCA (including, without limitation, the Canadian Securities
Legislation), the OBCA, the Interim Order, the Company Charter Documents, the
rules of the TSE and all other applicable legal requirements. Company's
obligation to call, give notice of, convene and hold the Company Shareholders
Meeting in accordance with this


                                       -37-
<PAGE>

Section 5.2(a) shall not be limited to or otherwise affected by the
commencement, disclosure, announcement or submission to Company of any
Acquisition Proposal.

                  (b) Subject to Section 5.2(c): (i) the Board of Directors of
Company shall unanimously recommend that Company's shareholders vote in favor of
and adopt and approve the Continuance and the Arrangement at the Company
Shareholders Meeting; (ii) the Circular shall include a statement to the effect
that the Board of Directors of Company has unanimously recommended that
Company's shareholders vote in favor of and adopt and approve the Continuance
and the Arrangement at the Company Shareholders Meeting; and (iii) neither the
Board of Directors of Company nor any committee thereof shall withdraw, amend or
modify, or propose or resolve to withdraw, amend or modify in a manner adverse
to Parent, the unanimous recommendation of the Board of Directors of Company
that Company's shareholders vote in favor of and adopt and approve the
Continuance and the Arrangement. For purposes of this Agreement, said
recommendation of the Board of Directors shall be deemed to have been modified
in a manner adverse to Parent if said recommendation shall no longer be
unanimous.

                  (c) Nothing in this Agreement shall prevent the Board of
Directors of Company from withholding, withdrawing, amending or modifying its
unanimous recommendation in favor of the Continuance and the Arrangement if (i)
a Superior Offer (as defined below) is made to Company and is not withdrawn,
(ii) neither Company nor any of its representatives shall have violated any of
the restrictions set forth in Section 6.2, and (iii) the Board of Directors of
Company concludes in good faith, after consultation with its outside counsel,
that, in light of such Superior Offer, the withholding, withdrawal, amendment or
modification of such recommendation is required in order for the Board of
Directors of Company to comply with its fiduciary obligations to Company's
shareholders under applicable law. Nothing contained in this Section 5.2 shall
limit Company's obligation to hold and convene the Company Shareholders Meeting
(regardless of whether the unanimous recommendation of the Board of Directors of
the Company shall have been withdrawn, amended or modified). For purposes of
this Agreement, "SUPERIOR OFFER" shall mean an unsolicited, bona fide written
offer made by a third party to consummate any of the following transactions: (i)
an amalgamation, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving Company pursuant to
which the shareholders of Company immediately preceding such transaction hold
less than 51% of the equity interest in the surviving or resulting entity of
such transaction; (ii) a sale or other disposition by Company of assets
(excluding inventory and used equipment sold in the ordinary course of business)
representing in excess of 51% of the fair market value of Company's business
immediately prior to such sale, or (iii) the acquisition by any person or group
(including by way of a tender offer or an exchange offer or issuance by
Company), directly or indirectly, of beneficial ownership or a right to acquire
beneficial ownership of shares representing in excess of 51% of the voting power
of the then outstanding shares of capital stock of Company, in each case on
terms that the Board of Directors of Company determines, in its reasonable
judgment (based on written advice of a financial advisor of nationally
recognized reputation) to be more favorable to Company shareholders from a
financial point of view than the terms of the Arrangement; PROVIDED, HOWEVER,
that any such offer shall not be deemed to be a "Superior Offer" if any
financing required to consummate the transaction contemplated by such offer


                                       -38-
<PAGE>

is not committed and is not likely in the judgment of Company's Board of
Directors to be obtained by such third party on a timely basis.

                                   ARTICLE VI
                              ADDITIONAL AGREEMENTS

including the status of product development efforts, properties, results of
operations and personnel of Company or Parent , as may be reasonably requested.
No information or knowledge obtained by Parent or Company in any investigation
pursuant to this Section 6.1 will affect or be deemed to modify any
representation or warranty contained herein or the conditions to the obligations
of the parties to consummate the Arrangement.

         6.2 NO SOLICITATION.

                  (a) From and after the date of this Agreement until the
Effective Time or termination of this Agreement pursuant to Article VIII,
Company and its subsidiaries will not, nor will they authorize or permit any of
their respective officers, directors, affiliates or employees or any investment
banker, attorney or other advisor or representative retained by any of them to,
directly or indirectly (i) solicit, initiate, encourage or induce the making,
submission or announcement of any Acquisition Proposal (as defined below), (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes or may
reasonably be expected to lead to, any Acquisition Proposal, (iii) engage in
discussions with any person with respect to any Acquisition Proposal, (iv)
subject to Section 5.2(c), approve, endorse or recommend any Acquisition

date on which the Circular is mailed to the shareholders of Company and the date
on which this Agreement is approved by the required Company Shareholder Vote,
this Section 6.2(a) shall not prohibit Company from furnishing nonpublic
information regarding Company and its subsidiaries to, entering into a
confidentiality agreement with or entering into discussions with, any person or
group in response to a Superior Offer submitted by such person or group (and not
withdrawn) if (1) neither Company nor any representative of Company and its


                                       -39-
<PAGE>

subsidiaries shall have violated any of the restrictions set forth in this
Section 6.2, (2) the Board of Directors of Company concludes in good faith,
after consultation with its outside legal counsel, that such action is required
in order for the Board of Directors of Company to comply with its fiduciary
obligations to Company's shareholders under applicable law, (3) (x) at least two
days prior to furnishing any such nonpublic information to, or entering into
discussions or negotiations with, such person or group, Company gives Parent
written notice of the identity of such person or group and of Company's
intention to furnish nonpublic information to, or enter into discussions or
negotiations with, such person or group and (y) Company receives from such
person or group an executed confidentiality agreement containing customary
limitations on the use and disclosure of all nonpublic written and oral
information furnished to such person or group by or on behalf of Company, and
(4) contemporaneously with furnishing any such nonpublic information to such
person or group, Company furnishes such nonpublic information to Parent (to the
extent such nonpublic information has not been previously furnished by Company
to Parent). Company and its subsidiaries will immediately cease any and all
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Acquisition Proposal. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
the preceding two sentences by any officer or director of Company or any of its
subsidiaries or any investment banker, attorney or other advisor or
representative of Company or any of its subsidiaries shall be deemed to be a
breach of this Section 6.2 by Company. In addition to the foregoing, Company
shall (i) provide Parent with at least forty-eight (48) hours prior notice (or
such lesser prior notice as provided to the members of Company's Board of
Directors but in no event less than eight hours) of any meeting of Company's
Board of Directors at which Company's Board of Directors is reasonably expected
to consider a Superior Offer and (ii) provide Parent with at least five (5)
business days prior written notice of a meeting of Company's Board of Directors
at which Company's Board of Directors is reasonably expected to recommend a
Superior Offer to its shareholders and together with such notice a copy of the
definitive documentation relating to such Superior Offer.

result in any person or group beneficially owning 10% or more of the total
outstanding voting securities of Company or any of its subsidiaries or any
amalgamation, consolidation, business combination, amalgamation, plan of
arrangement or similar transaction involving Company pursuant to which the
shareholders of Company immediately preceding such transaction hold less than

to purchase Company Common Shares (each, a "Company Stock Option") under the
Company Option Plans, whether or not vested, shall by virtue of the Arrangement
be assumed by Parent. Each Company Stock Option so assumed by Parent under this
Agreement will continue to have, and be subject to, the same terms and
conditions of such options immediately prior to the Effective Time (including,
without limitation, any repurchase rights or vesting provisions and provisions
regarding the acceleration of vesting on certain transactions, other than the
transactions contemplated by this Agreement), except that (i) each Company Stock
Option will be exercisable (or will become exercisable in accordance with its
terms) for that number of whole shares of Parent Common Stock equal to the
product of the number of Company Common Shares that were issuable upon exercise
of such Company Stock Option immediately prior to the Effective Time multiplied
by the Exchange Ratio, rounded down to the nearest whole number of shares of
Parent Common Stock and (ii) the per share exercise price for the shares of
Parent Common Stock issuable upon exercise of such assumed Company Stock Option
will be equal to the quotient determined by dividing the exercise price per
share of Company Common Shares at which such Company Stock Option was
exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded up to the nearest whole cent.

cause Company to fulfill and honor in all respects its obligations pursuant to
any indemnification agreements between Company and its directors and officers in
effect immediately prior to the Effective Time (the "INDEMNIFIED PARTIES") and

on the date hereof. The provisions of the Articles of Amalgamation and Bylaws of
Company as in effect on the date hereof will not be amended, repealed or
otherwise modified for a period of six (6) years from the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who,

use reasonable efforts to secure, or cause Canadian Sub to secure, directors'
and officers' insurance coverage for Company's directors and officers who are
currently covered by Company's directors' and officers' insurance, on a three
year "trailing" (or "run-off") basis and on terms no less advantageous then
those applicable to such directors and officers. If a trailing policy is not
available at a reasonable cost, then Parent agrees that for the period from the
Effective Time until three years after the Effective Time, Parent will cause
Company or any successor to Company to maintain Company's current directors' and
officers' insurance policy or an equivalent policy subject in either case to
terms and conditions no less advantageous to the directors and officers of
Company who are currently covered by Company's directors' and officers'
insurance, than those contained in the policy in effect on the date thereof,
covering claims made prior to or within three years after the Effective Time,
provided that such insurance remains available to Company or such successor at a
cost that is no greater than 150% of the cost to Company of such insurance as at
the date hereof.

judgment, affiliates of Company within the meaning of Rule 145 promulgated under

Parent with such information and documents as Parent reasonably requests for
purposes of reviewing such list. Each Company Affiliate Agreement will be in
full force and effect as of the Effective Time. Parent will be entitled to place
appropriate legends on the certificates evidencing any Parent Common Stock to be
received by a Company Affiliate pursuant to the terms of this Agreement, and to

immediately prior to the Closing Date. Parent shall receive from Company
evidence that Company's and each affiliate's (as applicable) plan(s) has been
terminated pursuant to resolution of each such entity's Board of Directors (the
form and substance of which resolutions shall be subject to review and approval
of Parent), effective as of the day immediately preceding the Closing Date. In
