  (m)          any and all Intellectual Property of the Vendor and the Vendor
               Affiliates and any tangible embodiments of any such property
               other than the Transferred Intellectual Property;

  (n)          any and all employee data other than the Employee Information;

  (o)          the books and records that the Vendor and the Vendor Affiliates
               are, in the reasonable opinion of Vendor's counsel, required by
               Law to keep;

  (p)          the Desktop Software and the Business Application Software;

  (q)          all stock or equity interests in any Person; and

  (r)          the other assets and rights listed in Schedule 2.2(r).

Section 2.3    Assignment of Contracts.

(1)  Nothing in this Agreement nor any other Transaction Document shall be
     construed as an attempt by the Parties to assign or as requiring the Vendor
     or a Vendor Affiliate to assign, or to cause the assignment of any Contract
     which, by its terms or as a matter of applicable Law, is not assignable in
     whole or in part without Consent, unless and until such Consent shall have
     been given. The Vendor shall use its Best Efforts and cooperate fully, and
     shall cause each Vendor Affiliate to use their respective Best Efforts and
     cooperate fully, with the Purchaser and its Affiliates to obtain as soon as
     commercially reasonable, all Consents provided that the failure to obtain
     any or all of such Consents prior to Closing shall not entitle the
     Purchaser to terminate this Agreement or not to complete the transactions
     contemplated hereby.

(2)  With respect to each Customer Contract to which the Vendor or a Vendor
     Affiliate, as applicable, has received the Consent to assign to the
     Purchaser on or before the Closing Date, the Purchaser and the Vendor or
     any Vendor Affiliate, as appropriate, acknowledge and agree that, as of the
     Closing and



                                      -22-

     pursuant to the terms and conditions of the Bill of Sale and Assignment and
     Assumption Agreement, all right, title and interest in and to such Customer
     Contract shall have been assigned to the Purchaser and the Purchaser shall
     have assumed all of the benefit and obligations under such Customer
     Contract, but only to the extent set forth in the form of such Customer
     Contract contained in the Agreed Documentation. With respect to each
     Customer Contract to which the Vendor or a Vendor Affiliate, as applicable,
     has not received the consent to assign to the Purchaser on or before the
     Closing Date (each such Customer Contract referred to herein as a
     "Subcontracted Customer Contract"), the Purchaser and the Vendor or any
     Vendor Affiliate, as appropriate, and as between and among them, as the
     case may be, acknowledge and agree that, as of the Closing and pursuant to
     the terms and conditions of the Bill of Sale and Assignment and Assumption
     Agreement, all right, title and interest in and to such Subcontracted
     Customer Contract shall have been conditionally assigned to the Purchaser
     and the Purchaser shall have conditionally assumed all of the benefits and
     obligations under such Subcontracted Customer Contract but only to the
     extent such benefits and obligations are set forth in the form of such
     Subcontracted Customer Contract contained in the Agreed Documentation.

(3)  Until the required Consent has been obtained and as with respect to the
     third party to such Subcontracted Customer Contracts, the Purchaser shall
     act as sub-contractor of the Vendor or any Vendor Affiliates, as
     applicable, in respect of such Subcontracted Customer Contracts pursuant to
     terms and conditions to be agreed between the Vendor and the Purchaser.

(4)  To the extent a customer and/or the Purchaser provides the Vendor with
     written evidence and establishes, to the reasonable satisfaction of the
     Vendor, a contractual relationship relating to the same subject matter of
     any Customer Contract (for purposes of this Subsection (4) the term
     Customer Contract shall include any Subcontracted Customer Contract) the
     terms and conditions of which are different from the terms and conditions
     of the form of Customer Contract set forth in the Agreed Documentation
     (such as a different signed version of such Contract, an addendum, exhibit,
     schedule or other documentation that purports to amend, modify, supplement
     or replace all or any part of such Contract or constitute a waiver
     thereof), the Vendor shall (i) pay to the Purchaser the full amount of any
     additional direct costs incurred by the Purchaser (including a reasonable
     overhead allocation) resulting from the discrepancy that the Purchaser,
     acting reasonably, cannot pass on to the customer, and (ii) indemnify the
     Purchaser for all Damages, any claim for such indemnification to be treated
     in the same manner as a claim asserted under Section 7.2(d).



                                      -23-

(5)  In an effort to preserve the Agreed Documentation, the Vendor and the
     Purchaser agree to deliver, as of the date hereof, a complete and accurate
     copy of all such documentation to be held by their respective Canadian
     Counsel.

(6)  Except as set forth in Section 5.2, the Purchaser may in its sole
     discretion, acting reasonably, decide whether or not to accept the
     assignment of any contract with a customer that provides for the sale of
     any of the Products and/or services related thereto the existence of which
     is made known to the Purchaser at any time after Closing. Any contract
     contemplated by this Section 2.3(6) that is not assumed by the Purchaser
     shall be treated pursuant to the terms and conditions of the Reseller,
     Maintenance and Referral Agreement.

(7)  Subject to the receipt of any required Consent, the Vendor shall use its
     Best Efforts, and shall cause each Vendor Affiliate, as applicable, to use
     their respective Best Efforts, to assign and transfer to the Purchaser the
     Equipment Leases. If any such Consent is not obtained for the assignment of
     any Equipment Lease (to the extent such Equipment Lease may relate to any
     Transferred Equipment) prior to Closing, the Vendor and the Vendor
     Affiliates shall buy out such portion of such Equipment Leases (but only to
     the extent as they relate to the Transferred Equipment) for which Consents
     have not been obtained and sell such Transferred Equipment, covered by such
     Equipment Leases to the Purchaser, free and clear of all Encumbrances, at
     the buy out value, which equipment shall form part of the Transferred
     Equipment.

(8)  The Purchaser shall be responsible and shall pay the Vendor and the Vendor
     Affiliates for any and all reasonable costs, including any Transfer Taxes,
     relating to the assignment and transfer of the Equipment Leases referred to
     above.

(9)  The Vendor shall use its Best Efforts, and shall cause the Vendor
     Affiliates to use their respective Best Efforts, to deliver to the
     Purchaser as soon as practicable after the Effective Time all
     documentation, including any license agreements, relating to the Third
     Party Software; provided, however, that the Vendor shall have no
     obligations to deliver documentation to the Purchaser in respect of any
     Third Party Software the license for which relates to lines of business or
     divisions of the Vendor or its Affiliates other than the Purchased
     Business.

Section 2.4    Assumption of Liabilities.

     Subject to Closing, effective as of and from the Effective Time, the
Purchaser shall assume and become responsible for, and shall perform, discharge
and pay



                                      -24-

when due the following obligations and liabilities (collectively, "Assumed
Liabilities"):

  (a)          all obligations and liabilities of any kind with respect to the
               Purchased Business to the extent such obligations and liabilities
               arise out of the conduct of the Purchased Business by the
               Purchaser or the use, ownership or operation of the Purchased
               Assets from and after the Effective Time; provided, however, that
               the Purchaser shall not assume nor shall the Purchaser become
               responsible or liable for any liability or obligation arising
               from or out of any breach or non-performance of any Contract
               occurring before the Effective Time;

  (b)          the current liabilities of the Purchased Business as at Closing;

  (c)          all obligations and liabilities relating to or arising from or in
               connection with the Purchaser's employment of each of the
               Transferred Employees from and after the Employee Start Date; and

  (d)          subject in all respects to Section 5.15, all obligations and
               liabilities of the Vendor and the Vendor Affiliates in respect of
               accrued and unused vacation relating to or arising from or in
               connection with the Vendor's or a Vendor Affiliate's employment
               of each of the Transferred Employees which obligations and
               liabilities existed and accrued at any or all times prior to the
               Employee Start Date.

     Nothing in this Section 2.4 shall be construed to negate any liability or
obligation explicitly assumed by the Purchaser elsewhere in this Agreement or in
any other Transaction Document. Other than those liabilities explicitly assumed
by the Purchaser in this Section 2.4 and elsewhere in this Agreement or any
other Transaction Document, the Purchaser, directly or indirectly, shall assume
no liabilities or obligations of Vendor or any Vendor Affiliate and shall not be
liable therefor.

AGREEMENTS, EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, WITH RESPECT TO THE

     Each of the Purchaser and the Guarantor further acknowledge that all
written and oral information (including analyses, financial information and

Guarantor from the Vendor and the Vendor Affiliates or any of their directors,

Purchased Business, the Purchased Assets or otherwise relating to the
transactions contemplated in this Agreement has been obtained for the
convenience of the Purchaser and the Guarantor only and the Vendor and the
Vendor Affiliates are not making any representation or warranty as to the
accuracy or completeness of such information except for the representations and
warranties of the Vendor contained in this Agreement or in any certificate
delivered pursuant hereto.

Section 2.7    Purchaser Affiliates.

     The Vendor acknowledges and agrees with the Purchaser and the Affiliates of
the Purchaser listed in Schedule 2.7 that:

   (a)         the Purchaser is purchasing that part of the Purchased Business
               and those of the Purchased Assets located in or relating to the
               United Kingdom (the "UK Business") as agent for and on behalf of
               the Affiliate of the Purchaser listed in Schedule 2.7 as the UK
               Affiliate (the "UK Affiliate") and references in this Agreement
               to the Purchaser shall for all purposes be construed as
               references to the UK Affiliate in so far as they relate to the UK
               Business;

   (b)         pursuant to Section 5.14(1), the UK Affiliate will be the

                                 PURCHASE PRICE

Section 3.1 Purchase Price.

     The purchase price (the "Purchase Price") payable by the Purchaser to the
Vendor for the Purchased Assets shall be an aggregate of $35,000,000 subject to
final adjustments under Section 3.4 and Article 7.

Section 3.2 Allocation of Purchase Price.

(1)  The Vendor and the Purchaser agree, as promptly as practicable following
     the date of this Agreement, but in any event not later than five (5)
     Business Days prior to the Closing Date, to allocate the Purchase Price, as
     set forth in Schedule 3.2(1), subject to adjustments under Section 3.4 and
     Article 7. Any subsequent adjustments to the allocation hereunder shall be
     reasonably agreed by the Vendor and the Purchaser.

(2)  The Vendor and the Purchaser hereby agree to execute and file or cause to
     be executed and filed all Tax Returns and prepare or cause to be prepared
     all financial statements, returns and other instruments on the basis of the
     allocations referred to in this Section 3.2, subject to adjustment in
     accordance with Section 3.4 and Article 7. The Vendor, the Vendor
     Affiliates, the Purchaser and any of their respective Affiliates shall not
     take any position on any Tax Return (including IRS Form 8594), before any
     Governmental Entity charged with the collection of any income Tax, or in
     any judicial proceeding relating to Taxes, that is inconsistent with the
     allocation of the Purchase Price established pursuant to this Section 3.2.

(3)  The Vendor and the Purchaser shall accumulate, and the Vendor shall cause
     each Vendor Affiliate, if applicable, to accumulate, the needed information
     to file a complete and timely Section 1060 statement (Form 8594) pursuant
     to the Code with respect to the purchase and sale of the Purchased Assets
     which are located in the United States as of the Closing Date.

(4)  Except as otherwise provided in this Agreement, none of the Purchaser, the
     Vendor or the Vendor Affiliates, if applicable, shall be responsible for
     any Tax liability or any other expense of any other Party to this Agreement
     resulting from the reporting and allocations made by such other Party as
     contemplated by this Section 3.2.

Section 3.3 Payment of Purchase Price.

     At the Closing, the Purchaser shall pay the Purchase Price to the Vendor,
on its own behalf and, as applicable, as agent for each of the Vendor
Affiliates, by way of electronic transfer of immediately available funds to such
bank account as the


                                       -27-

Vendor may designate to the Purchaser in writing at least two (2) Business Days
prior to the Closing Date.

Section 3.4       Adjustments to the Purchase Price.

(1)      Within thirty (30) days after the Closing, the Vendor shall prepare and
         deliver to the Purchaser an unaudited statement of management net
         assets and liabilities of the Purchased Business as of the Closing
         Date. The Vendor shall prepare such unaudited statement of management
         net assets and liabilities on a basis consistent with the preparation
         of the Financial Statements. Further, such unaudited statement of
         management net assets and liabilities will be used by the Purchaser for
         informational purposes, will be subject to change and will not
         necessarily reflect the final unaudited statement of net assets and
         liabilities of the Purchased Business as of the Closing Dates as
         described in Section 5.25.

(2)      Immediately following delivery of the audited financial statements as
         required pursuant to Section 5.25, the Vendor shall prepare and deliver
         to the Purchaser a draft statement of adjustment (the "Draft Statement
         of Adjustment") setting forth the amount, as of the Closing Date, of
         the current liabilities of the Purchased Business (the "Current
         Liabilities Amount"). The Draft Statement of Adjustment shall be
         prepared on a basis consistent with the preparation of the Financial
         Statements as described in Section 4.1(h) and shall include any
         adjustments to the management current liabilities discovered during the
         audit required pursuant to Section 5.25 that are applicable at the
         Closing Date. To the extent the Current Liabilities Amount, as adjusted
         pursuant to this Section 3.4(2) above, is greater than $8,500,000.00
         (the "Targeted Current Liabilities"), the Vendor shall pay the
         difference to the Purchaser. To the extent the Current Liabilities
         Amount, as adjusted pursuant to this Section 3.4(2) above, is less than
         the Targeted Current Liabilities, the Purchaser shall pay the
         difference to the Vendor. Such amount shall be referred to herein as
         the "Adjustment Amount" and payment of the Adjustment Amount by either
         the Vendor or the Purchaser shall be made within ten (10) Business Days
         of the finalization of the Statement of Adjustment as described in
         Section 3.5.

Section 3.5       Final Determination.

(1)      Within fifteen (15) Business Days following delivery of the Draft
         Statement of Adjustment, the Purchaser shall cause its auditors to
         review the Draft Statement of Adjustment and shall notify the Vendor in
         writing if it has any objections to the Draft Statement of Adjustment.
         The notice of objection must contain a statement of the basis of each
         of the Purchaser's objections and each amount in dispute. For greater
         certainty, the amount in dispute must relate to current liabilities
         that are to be assumed by the Purchaser and should not



                                      -28-

          include any liabilities that have been included in the audited
          financial statements solely for the purpose of compliance with GAAP.
          The Vendor shall request that its auditors provide access, upon
          reasonable request, to the Purchaser and its auditors to all work
          papers of the Vendor's auditors and the Vendor shall provide access,
          upon every reasonable request, to the Purchaser and its auditors to
          the accounting books and records and the appropriate personnel to
          verify the accuracy, presentation and other matters relating to the
          preparation of the Draft Statement of Adjustment. The Purchaser shall
          be deemed to have accepted the Draft Statement of Adjustment if it
          does not notify the Vendor of its objection within the said fifteen
          (15) Business Day period.

     (2)  If the Purchaser disputes the Draft Statement of Adjustment, the
          Parties  will work  expeditiously  and in good  faith in an attempt to
          resolve such dispute  within a further  period of twenty (20) Business
          Days after the date of  notification by the Purchaser to the Vendor of
          such dispute. In the absence of an agreement by the Parties, the final
          amount of the adjustment shall be determined  within ten (10) Business
          Days by a  nationally-recognized  firm (in both the United  States and
          Canada) of  certified  public  accountants  as may be agreed to by the
          Parties, and such determination shall be conclusive, final and binding
          on the  Vendor  and  the  Purchaser.  Such  firm of  certified  public
          accountants  shall  be  deemed  to be  acting  as  experts  and not as
          arbitrators.  The Vendor and the Purchaser will share equally all fees
          and expenses  charged by such  accountants  for resolving such matter.
          Immediately following the fifteen (15) Business Day period referred to
          in Section 3.5(1) or the resolution of any dispute in accordance  with
          the  foregoing,  as the case may be, the Vendor  shall  deliver to the
          Purchaser  the  final  Statement  of  Adjustment  (the  "Statement  of
          Adjustment")  together  with  any  report  of the  auditor's  produced
          thereon.  Such Statement of Adjustment shall be final and binding upon
          the Parties and shall not be subject to appeal, absent manifest error.

                                   ARTICLE 4
                         REPRESENTATIONS AND WARRANTIES

Section 4.1 Representations and Warranties of the Vendor.

          The Vendor represents and warrants to the Purchaser as follows, and
acknowledges that the Purchaser is relying on such representations and
warranties in connection with the transactions contemplated by this Agreement:

     (a)  Incorporation and Organization. Each of the Vendor and the Vendor
          Affiliates is a corporation  incorporated  and validly  existing under
          the laws of its jurisdiction of incorporation and has the

               requisite corporate power and authority to enter into, deliver
               and perform its obligations pursuant to each of the Transaction
               Documents to which it is or will become a party and to carry out
               the transactions contemplated hereunder and thereunder, as
               applicable. Each of the Vendor and the Vendor Affiliates is
               qualified, licensed or registered to carry on business in the
               jurisdictions in which the nature of the Purchased Business or
               Purchased Assets makes such qualification necessary.

   (b)         Validity of the Agreement. The execution and delivery of this
               Agreement and the Ancillary Agreements by the Vendor, the
               performance by the Vendor of its obligations hereunder and
               thereunder and the consummation by the Vendor of the transactions
               contemplated hereby and thereby have been duly authorized by all
               requisite corporate action on the part of the Vendor. The

               Agreements to which it is a party, the performance by each Vendor
               Affiliate of its obligations thereunder and the consummation by
               each Vendor Affiliate of the transactions contemplated thereby,
               have been duly authorized by all requisite corporate and
               shareholder action on the part of such Vendor Affiliate. This
               Agreement and all other Transaction Documents to which the Vendor
               and/or each Vendor Affiliate is or will be a party have been or
               at Closing will be duly and validly executed and delivered by the
               Vendor and/or each Vendor Affiliate, as the case may be, and
               (assuming due authorization, execution and delivery by the other
               parties hereto and thereto) constitute or at Closing will
               constitute legal, valid and binding obligations of the Vendor
               and/or each Vendor Affiliate, as the case may be, enforceable
               against it in accordance with their respective terms subject only
               to any limitation under applicable Laws relating to (A)
               bankruptcy, winding-up, insolvency, arrangement and other similar
               laws of general application affecting the enforcement of
               creditors' rights, (B) the discretion that a court may exercise
               in the grant of equitable remedies such as specific performance
               and injunction, and (C) the legality, validity or binding effect
               of the provisions of Section 5.23.

   (c)         No Conflict. The execution, delivery and performance of this
               Agreement by the Vendor and the execution, delivery and
               performance of the Transaction Documents by the Vendor and/or the
               Vendor Affiliates that are a party thereto, and the consummation
               of the transactions contemplated hereby and thereby:



                                       -30-

            (i)    do not (or would not with the giving of notice, the lapse of
                   time or the happening of any other event or condition):

                   (A)  conflict with or result in a violation of any provision
                        of the constating documents or by-laws of the Vendor or
                        any of the Vendor Affiliates; or

                   (B)  other than as a result of the failure to obtain any
                        Consent, conflict with or result in a breach of or a
                        default under, or give to any Person any right to
                        terminate, accelerate, cancel, suspend or modify, any

                   the Purchased Assets or the operation of the Purchased
                   Business; and

               condition to the lawful completion of the transactions

               notifications and Authorizations described in Schedule 4.1(d) (as
               determined in accordance with Section 5.5(1)), or that relate
               solely to the identity of the Purchaser or the nature of the
               business carried on by the Purchaser prior to Closing.

   (e)         No Other Agreements to Purchase. Except for the Purchaser's right
               under this Agreement, no Person has any written or oral agreement
               or option or any right or privilege capable of becoming such for
               the purchase or acquisition from the Vendor or any of the Vendor
               Affiliates of any of the Purchased Assets other than assets sold
               in the Ordinary Course.

   (f)         Title to Purchased Assets. Other than the Transferred
               Intellectual Property and the Vendor Licensed Intellectual
               Property, each of the Vendor and the Vendor Affiliates owns (with
               good title), or has a valid leasehold or license interest in, as
               the case may be, all of the

               Intellectual Property, the Vendor Licensed Intellectual Property
               and the Third Party Licensed Intellectual Property (including
               Third Party Licensed Intellectual Property subject to Consent),
               all of which are addressed in Section 4.1(s), include all rights
               and property necessary and sufficient, in all material respects,
               to carry on the Purchased Business as conducted immediately prior
               to Closing or at any time since September 1, 2001.

     (h)       Financial Statements. The unaudited management financial
               statements attached as Schedule 4.1(h) (the "Financial
               Statements") are true, correct and complete and present fairly
               the statement of assets and liabilities of the Purchased Business
               as of December 31, 2001, and the related statement of profit and
               loss of the Purchased Business for the fiscal year then ended.
               The Financial Statements have been compiled from the books and
               records of the Purchased Business and except as disclosed on
               Schedule 4.1(h), (i) have been prepared in accordance with U.S.
               GAAP and (ii) present fairly, in all material respects, the

               loss) of the Purchased Business, as the case may be, as of the
               date or for the period indicated. Except as disclosed in Schedule
               4.1(h), there is no liability or obligation of any kind, whether
               accrued, absolute, fixed, contingent, or otherwise, of the Vendor
               or any of its Subsidiaries that is not reflected or reserved
               against in the statement of assets and liabilities other than (A)
               liabilities incurred in the Ordinary Course since the Financial
               Statement Date, or (B) any such liability that would not be
               required to be presented in financial statements prepared in
               conformity with U.S. GAAP applied, in a manner consistent with
               past practice, in the preparation of the Financial Statements.

               Technology is a non-resident of Canada within the meaning of
               Section 116 of the Income Tax Act (Canada). Except for those sold
               by Architel and NN Technology, none of the Purchased Assets that
               are being sold by the Vendor Affiliates constitute "taxable
               Canadian property" as such term is defined within the meaning of
               Section 248 of the Income Tax Act (Canada).



                                      -32-

     (j)       Authorizations. To the Vendor's Knowledge, the Vendor and the
               Vendor Affiliates hold all Authorizations that are required for

               prior to Closing or any time since September 1, 2001 or for the
               ownership and use of the Purchased Assets. All such
               Authorizations are listed in Schedule 4.1(j). To the Vendor's
               Knowledge such Authorizations are in full force and effect and no
               Action has been taken or threatened in writing that would
               terminate or impair such Authorization.

     (k)       No Breach of Material Contracts. Except as disclosed in Schedule
               1.1(vvv) and other than license fees which may be owing under the

               Vendor Affiliates has performed all of the obligations required
               to be performed by it and is entitled to all benefits thereunder,
               and is not in breach or default in any material respect of any
               Material Contract. Each of the Material Contracts is in full
               force and effect, unamended, and except as set forth in Section
               1.1(vvv) and other than license fees which may be owing under the
               Third Party Licenses at Closing, there exists no default or event
               of default or event, occurrence, condition or act (including the
               purchase of the Purchased Assets) which, with the giving of
               notice, the lapse of time or the happening of any other event or
               condition, would become a default or event of default under any
               Material Contract other than any requirements to obtain the
               Consent of the other party. Schedule 1.1(vvv) contains a list of
               the Material Contracts setting out, in respect of each Material
               Contract, (i) the parties, (ii) any restrictions on (A)
               assignment or (B) the sale of all or substantially all of the
               assets of any Vendor Affiliate and (iii) the nature and extent of
               any default or event of default, thereunder and how such default
               or event of default has been addressed by the Vendor and/or the
               relevant Vendor Affiliate, as the case may be.

     (l)       No Breach of Other Contracts. Except for certain acts of default
               or breach which, in the aggregate, would not have a Material
               Adverse Effect none of the Vendor or the Vendor Affiliates, as
               the case may be, has violated or breached any of the terms or
               conditions of any Contract (other than the Material Contracts).

     (m)       Absence of Certain Changes or Events. Except as disclosed in
               Schedule 4.1(m), since the Financial Statement Date to the date
               of this Agreement, except as expressly contemplated by this
               Agreement or consented to in writing by the Purchaser, (a) no
               change or event has occurred that has had or would reasonably be


                                       -33-

                    expected to have a Material Adverse Effect and (b) no
                    material transaction, obligation or liability has been
                    undertaken or incurred by the Purchased Business outside the
                    Ordinary Course.

                    the Vendor or any of the Vendor Affiliates is a party to any
                    lease, sublease, license or contract in the nature of a
                    lease or conditional sales contract in respect of any
                    tangible personal property which is used exclusively in the
                    conduct of Purchased Business and the Vendor and the Vendor
                    Affiliates are in possession of all of the tangible personal
                    property which is the subject of the Equipment Leases.

          (o)       Books and Records. All accounting and financial books and
                    records of the Vendor and, to the Vendor's Knowledge, the
                    Vendor Affiliates relating to the Purchased Business have
                    been fully, properly and accurately kept and are complete in
                    all material respects. The books and records of the Vendor
                    and the Vendor Affiliates and other data or information
                    relating to the Purchased Business are not recorded, stored,
                    maintained, operated or otherwise wholly or partly dependent
                    upon or held by any means (including any electronic,
                    mechanical or photographic process, whether computerized or
                    not) which would not be available to a purchaser of the
                    Purchased Business in the Ordinary Course.

          (p)       Employee Relations.

               (i)     Except as disclosed in Schedule 4.1(p), none of the
                       Vendor or any of the Vendor Affiliates is party to or

                    Property used by, held for use by or necessary for the

                    Business as conducted immediately prior to Closing or at any
                    time since September 1, 2001, in all material respects.

          (t)       Rights to Third Party Licensed Intellectual Property.
                    Provided that the Third Party Licensed Intellectual Property
                    does not infringe the Intellectual Property rights of any
                    third Person (with respect to which the Vendor has no
                    Knowledge of any such infringement), the Vendor and the
                    Vendor Affiliates are licensed to use all Third Party

                    licenses as of the date of this Agreement is set out in
                    Schedule 1.1(z). Except as set forth in Schedule 4.1(s), the
                    Vendor has no Knowledge that any of the licensors of the
                    Third Party Licenses have threatened to withdraw, or would
                    be placed in a position that might require them to withdraw,
                    any services thereunder in connection with any part of the
                    Purchased Business or any of the Products.

          (u)       Ownership of Vendor Licensed Intellectual Property and No
                    Infringement of Third Party Intellectual Property Rights.
                    The Vendor or the Vendor Affiliates own all rights in and to
                    the Vendor Licensed Intellectual Property and the "Preside"
                    trademark identified in the Trademark License Agreement for
                    the purposes of conducting the Purchased Business as
                    conducted immediately prior to Closing or at any time since
                    September 1, 2001, in all material respects. Except as
                    disclosed in Schedule 4.1(r), the individuals identified in
                    Schedule 1.1(mmm) have no actual knowledge that the use of
                    the Vendor Licensed Intellectual Property or the "Preside"
                    trademark identified in the Trademark License Agreement for
                    the purposes of conducting the Purchased Business as
                    conducted immediately prior to Closing or at any time since
                    September 1, 2001 infringes or misappropriates the
                    Intellectual Property right of any third Person. Except as
                    disclosed in Schedule 4.1(r), the Vendor has no Knowledge of
                    any claims made against the Vendor or the Vendor Affiliates
                    during the past two (2) years that the conduct of the
                    Purchased Business as conducted immediately prior to Closing
                    or at any time since September 1, 2001 infringes or
                    misappropriates any Intellectual Property right of any third
                    Person or improperly discloses any Intellectual Property to
                    any other Person. Except as


                                       -38-

                    disclosed in Schedule 4.1(r), neither the Transferred
                    Intellectual Property, the Vendor Licensed Intellectual
                    Property or the "Preside" trademark identified in the
                    Trademark License Agreement is the subject of any Action.

          (v)       Transferred Intellectual Property and Vendor Licensed
                    Intellectual Property. All patents, registrations and
                    certificates issued by any Governmental Entity included in
                    the Transferred Intellectual Property are valid and
                    subsisting and have been properly maintained. Other than
                    Permitted Encumbrances, the Vendor has not granted to any
                    third Person any license or other right to any of the
                    Transferred Intellectual Property and the Vendor is not a
                    party to or bound by any contract or any other obligation
                    that limits or impairs its ability to transfer the
                    Transferred Intellectual Property or to license the Vendor
                    Licensed Intellectual Property. For greater certainty,
                    nothing in this Agreement, except to the extent set out in
                    Section 4.1(u), shall constitute a representation or
                    warranty that the Transferred Intellectual Property or the
                    Vendor Licensed Intellectual Property does not infringe or
                    misappropriate the Intellectual Property rights of any third
                    Person. The Vendor has no Knowledge that a third Person is
                    infringing or has infringed any foreign or domestic patent,
                    trademark, service mark, trade name or copyright that forms
                    a part of the Transferred Intellectual Property, or has
                    misappropriated or improperly disclosed any trade secret,
                    confidential information or know-how that forms a part of
                    the Transferred Intellectual Property.

          (w)       Products and Source Code. Except as disclosed in Schedule
                    4.1(w), none of the Vendor nor any of the Vendor Affiliates
                    has granted any rights to or has provided source code in
                    respect of any of the Transferred Intellectual Property to
                    any third Person, other than pursuant to escrow arrangements
                    in respect of source code required by software maintenance
                    agreements entered into in the Ordinary Course, the
                    particulars of which escrow arrangements, including the
                    parties thereto, the date and term thereof and the address
                    of the location at which the source code has been stored,
                    are listed in Schedule 4.1(w). Except as listed in Schedule
                    4.1(w), or as is permitted pursuant to any Contract, there
                    are no distributors, sales agents, representatives or any
                    other persons, including VARs, OEMs or resellers, who have
                    rights to market or license the Products at Closing.

                    Affiliates to pay Taxes for periods ending on or before the
                    Effective Date, will result in an Encumbrance on the
                    Purchased Assets.

          (y)       Tax Matters. Each of the Vendor and the Vendor Affiliates
                    listed below is registered for purposes of the GST
                    Legislation and PST Legislation with registration numbers as

                    and the Vendor Affiliates are conducting the Purchased
                    Business in all material respects in compliance with all
                    applicable Laws of each jurisdiction in which the Purchased
                    Business is carried on.

          (aa)      Environmental Matters. To the Vendor's Knowledge, none of
                    the Vendor or any Vendor Affiliate is in violation of any
                    Environmental Laws. There are no Hazardous Substances
                    located on or in any of the Leased Properties and no Release
                    of any Hazardous Substances has occurred on or from such
                    Leased Properties.

          (bb)      Leased Properties. Each Lease creates a valid leasehold
                    estate in the Leased Properties thereby demised and is in
                    full force and effect without amendment other than as

                    Knowledge, the lessor thereunder is in default in any
                    material respect under any Lease relating to the Leased
                    Properties nor shall the consummation of the transactions
                    contemplated hereby and under the Transaction Documents
                    cause the lessee to be in default thereunder.

          (cc)      Customers. Schedule 4.1(cc) contains a list of the ten (10)
                    largest customers of the Purchased Business (in terms of
                    sales) during the fiscal years ended December 31, 2000, and
                    December 31, 2001, showing the approximate total sales by
                    the Purchased Business to each such customer during the
                    fiscal years ended December 31, 2000 and December 31, 2001,

                    the Vendor or the Vendor Affiliates with respect to the
                    Purchased Business had any customer who accounted for more
                    than five percent (5%) of the sales of the Purchased
                    Business during the fiscal years ended December 31, 2000 and

Business for the purpose of allowing the Purchaser to investigate, at its own
expense, the condition, extent, quality, quantity or any other aspects of the
Purchased Assets and the compliance of the Vendor and the Vendor Affiliates with

to promptly obtain any such consent from such other party or parties in order to

(1)  The Purchaser or an Affiliate of the Purchaser shall be liable for and

     Act (Canada)


                                       -48-

         ("GST Legislation") in connection with the sale of the Purchased
         Business. However, the Vendor agrees to jointly elect with the
         Purchaser at the Purchaser's option under subsection 167(1) of the
         GST Legislation. If the Purchaser wishes to make such election, the
         Purchaser shall provide to the Vendor at Closing a duly completed Goods
         and Services Tax ("GST") Form #GST 44, "Election Concerning the
         Acquisition of a Business or Part of a Business" (the "GST Election")
         in the prescribed form and containing the prescribed information and
         the Vendor and the Purchaser will execute such form.

    (2)  The Purchaser or an Affiliate of the Purchaser shall file such joint
         elections with the return required to be filed by the Purchaser under
         the GST Legislation for the Purchaser's reporting period in which the
         sale is made, in compliance with the requirements of the GST
         Legislation. The Purchaser will indemnify and hold harmless the Vendor
         for all Taxes, interest and penalties that the Vendor may be required
         to pay should the joint elections described above not be available in
         the opinion of the Canada Customs and Revenue Agency.

    (3)  The Purchaser or an Affiliate of the Purchaser shall pay directly to
         the appropriate taxing authority, within the time specified therefor
         all applicable Taxes payable in connection with the purchase of the
         Purchased Assets, other than Taxes on any gain that may be realized on
         the sale of the Purchased Assets provided that if any such Taxes are
         required to be collected and remitted by the Vendor or a Vendor
         Affiliate, they shall be paid by the Purchaser to the Vendor or such
         Vendor Affiliate, at the Closing. The Purchaser shall indemnify and
         hold harmless the Vendor and the Vendor Affiliates for all Taxes,
         interests and penalties to the extent the Vendor or a Vendor Affiliate
         does not charge the Purchaser any Ontario, British Columbia or other
         applicable provincial sales tax at Closing and the Purchaser's claimed
         entitlement to an exemption is subsequently disallowed or not accepted
         by the Ontario, British Columbia or other applicable tax authority.

    (4)  If the Purchaser or an Affiliate of the Purchaser wishes to claim any
         exemption relating to, or a reduced rate of, Taxes in connection with
         the transactions contemplated herein, unless expressly stated otherwise
         in this Agreement, the Purchaser shall be solely responsible for
         ensuring that such exemption applies and, in that regard, shall provide
         the Vendor and the Vendor Affiliates at or prior to the Effective Time
         with its vendor permit number and/or any appropriate certificate of
         exemption and/or other document or evidence to support the claimed
         entitlement to such exemption by the Purchaser. The Purchaser shall
         indemnify and hold harmless the Vendor and the Vendor Affiliates for
         all Taxes, interests and penalties to the extent the Vendor or a Vendor
         Affiliate does not charge the Purchaser any



                                       -49-

          such Tax, and the claimed entitlement to an exemption by the Purchaser
          is subsequently disallowed or not accepted by the relevant
          authorities.

(5)       All ad valorem taxes, real property taxes, personal property taxes and
          similar obligations that are calculated on an annual or other periodic
          basis ("Property Taxes") attributable to the Purchased Assets with
          respect to the tax period in which the Closing Date occurs shall be
          apportioned as of the Closing Date between the applicable Vendor or
          Vendor Affiliate and the Purchaser determined by prorating such
          Property Taxes on a daily basis over the entire tax period.

(6)       If the Purchaser or an Affiliate of the Purchaser pays any Property
          Taxes for which the Vendor or any Vendor Affiliate is liable, the
          Vendor or such Vendor Affiliate shall promptly reimburse the
          Purchaser, and if the Vendor or any Vendor Affiliate pays any Property
          Taxes for which the Purchaser is liable, the Purchaser shall promptly
          reimburse the Vendor or any Vendor Affiliate. Payment shall be made
          promptly in cash upon receipt of a copy of any such supplemental bill
          of the amount necessary to accomplish such proration.

Section 5.14   Employees.

(1)       The Vendor and the Purchaser accept and agree that as of the UK
          Employee Transfer Date, the Employment Transfer Laws shall operate to
          transfer to the Purchaser (or an Affiliate of the Purchaser) the
          contract of employment of each UK Employee and accordingly the
          Purchaser shall employ, or cause to be employed, each UK Employee with
          effect from the UK Employee Transfer Date and the Purchaser shall
          treat or shall cause to be treated, each UK Employee's continuous
          period of service with the Vendor or a Vendor Affiliate as continuous
          with Purchaser (or an Affiliate of the Purchaser). With respect to
          each UK Employee, the Vendor and each applicable Vendor Affiliate and
          the Purchaser shall comply with their respective obligations under all
          Employment Transfer Laws applicable to each UK Employee including, in
          the case of the Vendor and Vendor Affiliates, informing and consulting
          with and providing written notices or communications to such UK
          Employees or their employee representatives or works councils
          ("Employees' Representatives") as required by Employment Transfer
          Laws. The Purchaser shall provide the Vendor with sufficient
          information to enable the Vendor and the Vendor Affiliates to carry
          out their duties with regard to providing information to and
          consulting with the UK Employees and any Employees' Representatives,
          or any applicable government authority pursuant to the Employment
          Transfer Laws and such other information as is reasonably requested by
          the Vendor and the Vendor Affiliates in respect of the UK Employees or
          any UK Employees' Representatives.


                                       -50-

(2)       The Parties acknowledge that Employment Transfer Laws shall not
          operate to transfer to the Purchaser (or an Affiliate of the
          Purchaser) the contract of employment of the Employee employed by the
          Vendor or a Vendor Affiliate whose work location is within France (the
          "French Employee") or of each Employee employed by the Vendor or a
          Vendor Affiliate whose work location is within Germany (each a "German
          Employee"). Accordingly, the Purchaser shall or shall cause a
          Purchaser Affiliate to enter into a three party agreement with the
          French Employee and with each German Employee, in the form set out in
          Schedule 5.14(2), pursuant to which the Purchaser or relevant
          Purchaser Affiliate shall offer employment to such French Employee and
          such German Employees, to commence effective as of the Employee Start
          Date. Such offers of employment shall be on terms and conditions on
          which such French Employee or such German Employees as applicable are
          currently employed by the Vendor or a Vendor Affiliate as disclosed to
          the Purchaser and shall remain open for acceptance until the Employee
          Start Date. Without limiting the generality of the foregoing, such
          offers of employment will include the terms and conditions set forth
          in Schedule 5.14(2), Section 5.15 and Section 5.18. The Purchaser
          shall provide the Vendor with sufficient information which the Vendor
          reasonably requires in order to provide information to and consult
          with the French Employee and the German Employees and the work
          councils representing such French Employee and the German Employees
          concerning the offer of employment referred to in this Section 5.14(2)
          and any measures proposed by the Purchaser or an Affiliate of the
          Purchaser which may affect the French Employee or the German
          Employees.

(3)       The Vendor covenants with the Purchaser that the Vendor will fully
          indemnify the Purchaser and hold the Purchaser and any of its
          Affiliates harmless against all Damages arising:

     (a)       from the employment or termination of employment by the Vendor or
               any Vendor Affiliate of any of the UK Employees, the French
               Employee or the German Employees prior to the Employee Start
               Date, or any failure by the Purchaser or any Affiliate of the
               Purchaser to employ the UK Employees, French Employee or German
               Employees in the period commencing on the Closing and ending on
               the Employee Start Date which arise or are alleged to arise
               against the Purchaser by virtue of the operation of the
               Employment Transfer Laws, provided that the claim is not made as
               a result of any failure by the Purchaser or an Affiliate of the
               Purchaser to provide information for the purposes of
               consultation, any materially detrimental change or proposed
               change by the Purchaser or any Affiliate of the Purchaser to the
               remuneration,



                                       -51-

               benefits (including any pensions benefits), terms and conditions
               of employment, or the working conditions of any UK Employee,
               French Employee or German Employees; or

     (b)       at any time whether before or after the Effective Time and which
               are brought by any Person (which shall include any individual or
               organisation, trade union, labour union, works council or
               employee representative) other than a UK Employee, the French
               Employee, the German Employees, or an Employees' Representative
               which arise or are alleged to arise against the Purchaser by
               virtue of the operation of the Employment Transfer Laws provided
               that the claim is not made as a result of any failure by the
               Purchaser to provide information for the purposes of
               consultation.

(4)       If the Employment Transfer Laws do not or are found not to apply to
          any person who is a UK Employee, the Purchaser agrees that following
          the Closing Date:

     (a)       the Purchaser (or any of its Affiliates) shall within five (5)
               Business Days of being so requested by the Vendor make to each
               such UK Employee an offer in writing to employ him or her under a
               new contract of employment to take effect upon the termination
               referred to below; and

     (b)       the offer to be made will, subject to the exceptions set forth in
               Schedule 5.14(5) (i) be on terms and conditions substantially the
               same, in the aggregate, as the terms and conditions on which such
               UK Employee is employed immediately prior to the Closing Date as
               disclosed in this Agreement and (ii) provide that his or her
               period of continuous service with the Vendor or Vendor Affiliate,
               as applicable, shall be counted as continuous service with the
               Purchaser (or the relevant Affiliate of the Purchaser).

            If such offer is accepted, Vendor or the relevant Vendor Affiliate
            shall terminate the employment of the UK Employee concerned.

(5)       The Purchaser shall give offers of employment pursuant to Section
          5.14(6) by means of a letter substantially in the form attached hereto
          as Exhibit "J", to the Designated Employees to commence effective as
          of the Employee Start Date. Subject to the exceptions set forth in
          Schedule 5.14(5), such offers of employment shall be on terms and
          conditions substantially the same, in the aggregate, as the terms and
          conditions on which such Designated Employees are currently employed
          by the Vendor or a Vendor Affiliate as disclosed to the Purchaser in
          this Agreement. Without limiting the generality of the



                                       -52-

          foregoing, such offers of employment will include the terms and
          conditions set forth in Section 5.14(5) and (6), Section 5.15 and
          Section 5.18.

(6)       The Purchaser shall, not more than five (5) days after the later of
          (i) the date of this Agreement or (ii) the date of provision of all of
          the information in Section 5.16(3) by the Vendor, deliver the offers
          of employment contemplated by Section 5.14(5) accompanied by all
          information reasonably necessary for Designated Employees to properly
          consider such offers, such offers to remain open for acceptance for
          five (5) Business Days, provided that the fifth day is at least two
          (2) Business Days before the Closing Date. With respect to Leave
          Employees and Loaned Employees, (y) each Leave Employee shall be
          maintained as an Employee of the Vendor or a Vendor Affiliate, as
          applicable, until such time as the Leave Employee is able to return to
          work and perform, with or without reasonable accommodation, the
          essential functions of such Leave Employee's position, at which time
          the Purchaser shall provide such Leave Employee with a written offer
          or employment, such offer to remain open for five (5) days, provided
          that the Purchaser is not required to offer employment to any Leave
          Employee unless the Leave Employee is so able to return to work and
          perform the essential functions of the position within twelve (12)
          months of the Closing Date and (z) each Loaned Employee shall be
          maintained as a Loaned Employee of the Vendor or a Vendor Affiliate,
          as applicable, until such time as the Employee is authorized to work
          for the Purchaser in the United States or Canada, as applicable
          (subject to earlier termination in accordance with the Loaned Employee
          Agreement), five (5) days prior to which time the Purchaser shall
          provide such Employee with a written offer of employment, such offer
          to remain open for five (5) days; provided that, if the Purchaser does
          not have at least five (5) days notice of such authorization, the
          offer shall be made upon the Purchaser first receiving notice that the
          Loaned Employee is or will be so authorized. The Purchaser and the
          Vendor and the Vendor Affiliates shall cooperate with each other in
          facilitating the employment by the Purchaser or an Affiliate of the
          Purchaser of any Leave Employee or Loaned Employee pursuant to this
          Section 5.14 it being understood that the offer of employment will be
          on the same terms as provided to Designated Employees pursuant to
          Section 5.14(5). The Purchaser shall advise the Vendor in writing
          within five (5) days following expiry of the offers of employment as
          to which Designated Employees did not accept such offer of employment.
          Each Transferred Employee's employment with the Vendor or a Vendor
          Affiliate, as applicable, shall terminate by virtue of such employee's
          acceptance and commencement of employment with the Purchaser or an
          Affiliate of the Purchaser, such termination to be effective as of the
          Employee Start Date; and the Vendor or the Vendor Affiliate, as
          applicable, shall, subject to Section 5.19, provide to each
          Transferred Employee all entitlements of every nature or kind owing to



                                       -53-

          such Transferred Employee to and by the date of termination of
          employment, including all applicable salary, bonus, incentive pay,
          notice of termination, payment in lieu of notice or severance, whether
          pursuant to contract, statute (including the Worker Adjustment
          Retraining Notification Act and similar laws) or otherwise.

(7)       The Vendor and the Vendor Affiliates shall remain responsible for any
          and all costs and liabilities associated with (i) any UK Employee or
          Brazil Employee who terminates his employment prior to the Employee
          Start Date or who elects not to work for the Purchaser, save where
          such termination or election is as a result of or related to any act
          or omission by the Purchaser including any proposed change by the
          Purchaser or any Affiliate of the Purchaser to the remuneration,
          benefits (including any pension benefits), terms and conditions of
          employment, or the working conditions of any UK Employee or the Brazil
          Employee, and (ii) the Designated Employees, Leave Employees, Loaned
          Employees, French Employee, and German Employees who receive an offer
          of employment from the Purchaser in accordance with Section 5.14(2),
          (5) or (6) but who do not accept such offer or commence employment
          with the Purchaser or an Affiliate of the Purchaser and (iii) the
          Employees who are not listed as Designated Employees, Leave Employees,
          Loaned Employees, French Employees and German Employees or UK
          Employees on Schedule 1.1(jj) and the Excluded Employees. Prior to
          Closing, with respect to any UK Employee and Brazil Employee and,
          prior to acceptance or expiration, as the case may be, of any offer of
          employment by the Purchaser to any Designated Employee, Leave
          Employees, Loaned Employees, French Employees and German Employees
          with respect to such Employees, neither the Vendor nor any Affiliate
          of the Vendor shall take any actions: (a) to offer alternative
          employment within the operations of the Vendor or any Affiliate of the
          Vendor to any such Employee, except as otherwise agreed to by the
          Purchaser in writing; or (b) to discourage or prevent any such
          Employee from becoming a Transferred Employee.

(8)       For a period of twelve (12) months following the Closing Date, the
          Purchaser shall not knowingly, except with the Vendor's prior written
          consent, which consent shall not be unreasonably withheld, make any
          offers of employment to any of the Vendor's or the Vendor Affiliates'
          employees, or knowingly hire (as an employee or in any other capacity)
          any of said employees, including the Designated Employees who have
          rejected the Purchaser's offer of employment described above,
          provided, however, that nothing in this provision shall prevent the
          Purchaser from making generalized employment searches, by
          advertisement or by engaging firms to conduct searches that are not
          focused on the above mentioned Employees and hiring any Transferred
          Employees found through such searches.



                                       -54-

(9)       For a period of twelve (12) months following the Employee Start Date,
          none of the Vendor or the Vendor Affiliates shall knowingly solicit
          for employment or knowingly hire (as an employee or in any other
          capacity) any Transferred Employee, or any Person that is an employee
          of the Purchaser or any affiliate of the Purchaser immediately prior
          to the Effective Time; provided, however, that nothing in this
          provision shall prevent the Vendor or the Vendor Affiliates from
          making generalized employment searches, by advertisement or by
          engaging firms to conduct searches that are not focused on Transferred
          Employees and hiring any Transferred Employees found through such
          searches.

(10)      With respect to Transferred Employees employed in the United States,
          nothing in this Agreement is intended to create an employment
          relationship between the Purchaser (or an Affiliate of the Purchaser)
          and such Transferred Employee other than an at-will employment
          relationship.

(11)      Notwithstanding the execution and delivery of this Agreement, the
          contracts of employment of the UK Employees shall not transfer to the
          UK Affiliate until the Vendor and each relevant Vendor Affiliate has
          provided information to and consulted with the UK Employees and/or
          Employees' Representatives of the UK Employees pursuant to the
          Employment Transfer Laws. The Vendor and each relevant Vendor
          Affiliate shall as soon as possible following execution of this
          Agreement provide information to and consult with the UK Employees
          and/or Employees' Representatives of the UK Employees and shall give
          notice to the German Employees pursuant to the Employment Transfer
          Laws and shall not unreasonably delay completion of same. Upon
          completion of such consultation with the UK Employees and/or the
          Employees' Representatives of the UK Employees, Vendor shall without
          delay deliver to Purchaser a certificate to that effect, and such
          certificate shall be regarded as conclusive evidence that such
          consultation has taken place.

(12)      Except as otherwise permitted under this Agreement, neither the Vendor
          nor the Vendor Affiliates shall make any claim against the Purchaser
          or the Transferred Employees which claim arises under any employment
          agreement, confidentiality or non-competition agreement between any
          Transferred Employee and the Vendor or the Vendor Affiliates solely by
          virtue of the Transferred Employees' employment by the Purchaser or an
          Affiliate of the Purchaser in the Purchased Business.

(13)      The Parties agree that Schedule 5.14(13) to this Agreement shall
          govern, except as specifically addressed in this Agreement, the
          treatment of the Brazil Employee.



                                       -55-

Section 5.15  Vacation.

(1)       On or immediately before Closing the Vendor shall deliver to the
          Purchaser an updated Schedule 1.1(jj) and will further update such
          Schedule to set forth (i) all accrued and unused vacation expressed in
          number of days due and owing to and (ii) the applicable vacation
          entitlement for the Designated Employees, the French Employee, the
          German Employees, the Brazil Employee, the UK Employees, the Leave
          Employees and the Loaned Employees up to the Employee Start Date and
          the Vendor's calculation of the total dollar amount of pay for such
          accrued and unused vacation days, and the Purchaser or an Affiliate of
          the Purchaser shall grant each Transferred Employee paid time off in
          an amount equal to the accrued unused vacation days for such
          Transferred Employee set forth in such updated Schedule 1.1(jj) or, to
          the extent permitted by applicable Law, pay all or any portion to each
          such Transferred Employee his or her vacation pay entitlement with
          respect to such accrued unused vacation days. At the Employee Start
          Date the Vendor shall pay to the Purchaser in respect of the relevant
          Transferred Employees, an amount equal to the vacation pay accrual.

(2)       Notwithstanding anything to the contrary in Article 7 herein, the
          Vendor shall indemnify and save the Purchaser Indemnified Parties
          harmless of and from any Damages suffered by them in respect of (i)
          any failure to pay to the Purchaser the amounts contemplated by
          Section 5.15(1) and (ii) any error in the calculation of such amounts
          and the Parties agree that Section 7.4(1) shall have no application to
          the amounts payable to the Purchaser pursuant to this Section 5.15(2).

(3)       Notwithstanding anything to the contrary in Article 7 herein, the
          Purchaser shall indemnify and save the Vendor Indemnified Parties
          harmless of and from any Damages suffered by them in respect of any
          failure of the Purchaser to abide by its obligations under Section
          5.15(1) and the Parties agree that Section 7.4(2) shall have no
          application to the amounts payable to the Vendor pursuant to this
          Section 5.15(3).

Section 5.16  Parties' Responsibility.

(1)       Subject to Section 5.19, Section 5.16(2) and except as provided in the
          Loaned Employee Agreement, the Vendor and the Vendor Affiliates will
          be responsible for and bear and discharge any and all costs,
          obligations, Taxes and liabilities, in the case of each Transferred
          Employee accrued up to the Employee Start Date (including all
          liabilities arising from matters occurring at or prior to such
          Employee Start Date) for or in respect of the employment in the
          Purchased Business of such Transferred Employee. Without limiting the
          generality of the foregoing:



                                       -56-

     (a)       the Vendor shall, and shall cause the Vendor Affiliates to, pay
               and remain liable for any and all liability for claims of
               Transferred Employees under applicable workers' compensation Laws
               that were existing as at, or accrued to the Employee Start Date
               including claims filed after such time but only to the extent
               that such claims are: (x) based on accidents, injuries or
               illnesses incurred prior to such time, or (y) determined by
               applicable workers' compensation Laws that relate to such
               Transferred Employee's employment with the Vendor or a Vendor
               Affiliate in the period prior to such time, but excluding any
               liabilities with respect to reemployment obligations imposed on
               the Purchaser pursuant to such Laws that may apply to such
               Transferred Employees; provided that this Section 5.16 shall not
               operate to preclude the apportionment of liability between the
               Vendor or the Vendor Affiliates on the one hand and the Purchaser
               or the Purchaser Affiliates on the other hand, in accordance with
               applicable workers' compensation Laws;

     (b)       the Vendor shall, and shall cause the Vendor Affiliates to, in a
               manner consistent with applicable workers' compensation Laws, pay
               and shall remain liable for any and all workers' compensation
               assessments, penalties, fines, levies, charges, surcharges or
               other amounts that may be assessed with respect to Transferred
               Employees before or after the Employee Start Date but only to the
               extent that such assessments, penalties, fines, levies, charges,
               surcharges or other amounts are attributable to the period prior
               to the Employee Start Date;

     (c)       the Vendor shall, and shall cause the Vendor Affiliates to,
               remain responsible for the adjudication of claims by Transferred
               Employees under the Employee Plans.

(2)       Notwithstanding any provision in the Loaned Employment Agreement, the
          Purchaser will be responsible for and bear and discharge any and all
          costs, obligations, Taxes and liabilities related to its employment of
          each Transferred Employee. The Purchaser shall indemnify the Vendor
          and any Vendor Affiliate, as applicable, for Damages incurred by such
          Person as a result of (i) a change in any Transferred Employee's
          compensation, benefits, or any other term or condition of employment
          after the applicable Employee Start Date until the twelve (12) month
          anniversary of such Employee Start Date and (ii) any materially
          detrimental change or proposed change to the remuneration, benefits
          (including any pension benefits), terms and conditions of employment
          or the working conditions of any UK Employee, French Employee or
          German Employee made by the Purchaser or an Affiliate of the Purchaser
          as of or prior to the Employee Start Date.



                                       -57-

(3)       Immediately following the date of this Agreement the Vendor and/or the
          Vendor Affiliates, as appropriate, shall deliver to the Purchaser the
          following information with respect to each Designated Employee, French
          Employee, German Employee, Leave Employee, Loaned Employee, Brazil
          Employee and each UK Employee: (A) name; and (B) global identification
          number assigned by the Vendor.

(4)       Except as specifically permitted pursuant to the terms and conditions
          of the Intellectual Property License Agreement or any other
          Transaction Document, the Vendor and each Vendor Affiliate agree to

          Intellectual Property and the Products immediately following the
          Effective Time.

Section 5.17  Cooperation with Respect to Compensation and Benefits Issues.

          After the date hereof, the Vendor and the Purchaser shall co-operate
promptly and in good faith in implementing the transition of coverage of
Transferred Employees from the Employee Plans to the Purchaser's Employee Plans
including the provision of information (including information regarding periods
of leave or breaks in service with respect to the Employees whose work location
is in the United States) required to ensure the participation of the Transferred
Employees in the Purchaser's Employee Plans in accordance with Section 5.18. The
Vendor and the Purchaser further agree that such Parties shall share all
information required to administer the Employee Plans and the Purchaser's
Employee Plans and all requests for such information shall be handled in a
timely manner and transmitted in a reasonable format.

Section 5.18  Employees and Employee Plans.

          As of the later of the Employee Start Date or the provision of all of
the information in Section 5.16(3) and Section 5.17 by the Vendor, each
Transferred Employee, shall cease participating in, being covered by and
accruing benefits under the Employee Plans and shall be eligible to immediately
commence participation in the Purchaser's Employee Plans save and except the

herein, each Transferred Employee and, as applicable, such Employee's eligible
dependants, shall participate in, be covered by and accrue benefits under the
Purchaser's Employee Plans from and after the Employee Start Date. With respect
to the Purchaser's Employee Plans in existence as of the Closing Date, the
Purchaser shall, to the extent permitted by applicable Law, honour the
Transferred Employees' credited service date for purpose of determining plan
eligibility for membership and vesting under such Purchaser's Employee Plans,
but not for purposes of benefits or contribution calculations. For greater
certainty, service with the Vendor shall be recognized by the Purchaser in
respect of the Transferred Employee's rights on termination of employment with
the Purchaser. With respect to health, life, welfare and other



                                       -58-

group benefits in the Purchaser's Employee Plans, the Purchaser shall, to the
extent agreed by the provider of such benefit, waive evidence of insurability
and pre-existing conditions limitations (except as may exist under the Employee
Plans).

Section 5.19  Commission and Incentive Payment.

          The Vendor or a Vendor Affiliate, as appropriate, shall retain
responsibility for and shall pay to the Transferred Employees that portion of
the 2001 and 2002 Success incentive payment to which such Transferred Employees
are entitled under the Vendor's Success incentive payment Plan and all bonuses
of any kind earned and payable in connection with the consummation of the
transactions contemplated by this Agreement. Such payments will be made or a

Purchaser or a Purchaser Affiliate, as appropriate, shall retain responsibility
for and shall pay to the Transferred Employees all earned but unpaid sales

Section 5.20  Risk of Loss.

          From the time of execution of this Agreement up to the Effective Time,
the Purchased Assets shall be and remain at the risk of the Vendor and the
Vendor Affiliates, as the case may be. If, prior to the Effective Time, all or
any material part of the Purchased Assets is lost, destroyed or damaged by fire
or any other casualty or shall be appropriated, expropriated or seized by any
Governmental Entity or other lawful authority, the Purchaser shall have the
option, exercisable by notice in writing given within four (4) Business Days
after the Purchaser receives notice in writing from the Vendor of such loss,
destruction, damage, appropriation, expropriation or seizure:

     (a)       to reduce the Purchase Price by an amount equal to the cost of
               repair or, if destroyed or damaged beyond repair or appropriated,
               expropriated or seized, by an amount equal to the replacement
               value of the property and Purchased Assets so damaged or
               destroyed or appropriated, expropriated or seized and to complete
               the transactions contemplated hereby; or

     (b)       to complete the transaction contemplated in this Agreement
               without reduction of the Purchase Price, in which event all
               proceeds of insurance or compensation for destruction or damage
               or appropriation, expropriation or seizure will be payable to the
               Purchaser and all right and claim of the Vendor and the Vendor
               Affiliates to any such amount not paid by the time of the Closing
               Date will be assigned to the Purchaser.

If the Purchaser receives notice from the Vendor pursuant to the foregoing
provisions of this Section 5.20 less than four (4) Business Days prior to
Closing Date,



                                      -59-

the Closing Date will be postponed to the earliest Business Day that is four (4)
Business Days after the date on which such notice is received by the Purchaser.
If the Purchaser elects to reduce the Purchase Price pursuant to the foregoing
provisions of this Section 5.20, the Vendor and the Purchaser will prior to the
time of Closing determine the amount of the reduction to the extent that it is
then determinable and will undertake to adjust such amount after Closing, if
necessary.

Section 5.21  Deletion of Non-Transferred Software.

          The Purchaser agrees that, following the Closing, the Purchaser shall
not use and shall cause each of the Purchaser's Affiliates not to use any items
of software loaded on the Transferred Equipment (including the Desktop Software
and the Business Application Software) as of the Closing Date which are not
transferred or licensed to the Purchaser pursuant to this Agreement, any other
Transaction Document or otherwise. The Purchaser shall, as soon as is reasonably
practical, and in any event no later than forty-five (45) days following the
Closing, delete all such software from any of the Transferred Equipment on which
it is installed.

Section 5.22  Removal of Transferred Equipment.

          The Purchaser covenants and agrees to remove or cause to be removed
all of the Transferred Equipment located at premises of the Vendor and the
Vendor Affiliates other than the Leased Properties as soon as practicable after
Closing and, in any event, no later than the expiry date of the Premises License
Agreement in respect of such premises, if any. The Purchaser shall remove the
Transferred Equipment (i) at its sole cost and expense and (ii) without undue
interference to the ordinary conduct of the business of the Vendor or any Vendor
Affiliate, as applicable, during such hours and on such date or date as the
Vendor or the applicable Vendor Affiliate agree, acting reasonably.

Section 5.23  Non-Competition.

(1)       For a period of eighteen (18) months from the Closing Date and other
          than as permitted in any Transaction Document, neither the Vendor nor
          any of its Affiliates shall directly or indirectly sell, provide,
          distribute, deliver, develop, produce or market products that are
          directly in competition with and perform the same or substantially the
          same functions as those performed, on the date of this Agreement, by
          the Products (the "Competitive Products").

(2)       For greater certainty, the prohibition in subsection (1) shall not
          apply to any of the following:

     (a)       The sale, provision, distribution, delivery, marketing, design,
               development or production of Competitive Products by the Vendor
               or any of its Affiliates that are not sold as separate components
               but



                                      -60-

               that are integrated into, or utilized as part of, a broader
               product offering within a customer's network;

     (b)       The ownership by the Vendor or any of its Affiliates of (A) a
               Person that engages, directly or indirectly, in the sale of
               Competitive Products if such sales account for less than fifteen
               percent (15%) of such Person's consolidated annual revenues for
               the fiscal year preceding the acquisition of such Person by the
               Vendor or its Affiliates or (B) a Person (provided such Person
               has been acquired by the Vendor or any of its Affiliates within
               four (4) months from the Closing Date) that engages, directly or
               indirectly, in the sale of Competitive Products if such sales
               account for fifteen percent (15%) or more of such Person's
               consolidated annual revenues for the fiscal year preceding the
               acquisition of such Person by the Vendor or any of its Affiliates
               and if the Vendor or any of its Affiliates divests itself, within
               eight (8) months from having acquired ownership of such Person,
               of that portion of the business of such Person which involves the
               sale of Competitive Products; or

     (c)       The Vendor or any of its Affiliates acting as a reseller,
               consultant or systems integrator with respect to the Products (if
               acquired, directly or indirectly, from the Purchaser), or
               Competitive Products sold, provided, distributed, delivered,
               designed, developed, produced or marketed by Persons other than
               the Vendor or any of its Affiliates, including the implementation
               or modification thereof, provided that such Competitive Products
               are not sold as separate components but are in each instance
               integrated into, or utilized as part of a broader offering of
               combined hardware and software components of the Vendor or any of
               its Affiliates.

(3)       Each of the Vendor and its Affiliates understands that the Purchaser
          shall be entitled to protect and preserve the going concern value of
          the Purchased Business to the extent permitted by Law and that the
          Purchaser would not have entered into this Agreement absent the
          provisions of this Section 5.23. Notwithstanding any other provision
          of this Agreement, it is understood and agreed that the remedy of
          indemnity payments and other remedies at law would be inadequate in
          the case of any breach of the covenants contained in this Section
          5.23; the Purchaser shall be entitled to equitable relief, including
          the remedy of specific performance, with respect to any breach or
          attempted breach of such covenants.



                                      -61-

Section 5.24  Bulk Sales Compliance.

          The Purchaser hereby waives compliance by the Vendor and the Vendor
Affiliates with any Laws governing bulk sales (to the extent such Laws are
applicable to the transactions contemplated by this Agreement). The Vendor
agrees to execute and deliver or cause to be executed and delivered to the
Purchaser, at or prior to the Closing, any further documents or affidavits
pursuant to the Bulk Sales Act (Ontario) as may be reasonably requested by the
Purchaser with respect to Architel.

Section 5.25  Required Audited Financial Statements.

(1)       The Vendor shall prepare and deliver to the Purchaser with respect to
          the Purchased Business prior to the date that is sixty (60) days after
          the Closing Date, audited statements of net assets and liabilities,
          profit and loss, and cash flows as of and for each of the periods
          ended as described in Schedule 5.25. The Vendor shall also prepare and
          deliver no later than sixty (60) days after the Closing Date unaudited
          statements of net assets and liabilities as of the Closing Date and
          for any interim quarter end, and unaudited statements of profit and
          loss, and cash flows for the Purchased Business for the period
          beginning on January 1, 2002 and ending on the Closing Date as well as
          for any interim quarter end. In each case, the audited and unaudited
          financial statements, as the case may be, prepared and delivered by
          the Vendor shall fairly present the financial position and results of
          operations and cash flows of the Purchased Business as of and for each
          of the periods indicated in accordance with U.S. GAAP consistently
          applied. The Vendor understands that such financial statements will be
          filed or used to prepare filings with the Securities and Exchange
          Commission of the United States (the "SEC"). The Vendor will assist,
          and request its accountants to assist, with respect to such filings
          and any other filings with the SEC or any other offering documents
          that include such financial statements, and the Purchaser shall pay
          the cost of any consent or comfort letter of the Vendor's accountants
          required in connection with the inclusion of such financial statements
          in filings or offering documents. The Vendor agrees to pay the cost of
          the audit fees associated with this requirement.

                                   ARTICLE 7
                          SURVIVAL AND INDEMNIFICATION

Section 7.1   Survival of Representations, Warranties and Covenants.

(1)       The representations and warranties of the Vendor contained in this
          Agreement or certified by the certificate delivered to the Purchaser
          pursuant to Section 6.1(a) shall survive the Closing and,

          the Closing Date and any claim in respect thereof shall be made in
          writing during such time period (in which event the representations
          and warranties to which such claim relates shall survive in respect of
          such claim until the final settlement or termination of such claim)
          and shall be subject to Section 7.5 and Section 7.6 save and except
          that a claim in respect of any of such representations and warranties

(2)       The representations and warranties of the Purchaser contained in this
          Agreement or certified by the certificate delivered to the Vendor
          pursuant to Section 6.2(a) shall survive the Closing and,
          notwithstanding the Closing and any investigation made by or on behalf
          of the Vendor and the Vendor Affiliates, shall continue in full force
          and effect for the benefit of the Vendor and the Vendor Affiliates for
          a period of eighteen (18) months after the

       period (in which event the representations and warranties to

       until the final settlement or termination of such claim) and
       shall be subject to Section 7.5 and Section 7.6 save and except
       a claim in respect of any of such representations and
       warranties involving fraud or fraudulent misrepresentation may

       Subject to Section 7.4, the Vendor shall indemnify and save the
Purchaser, the Guarantor, their respective Affiliates and each of their
respective officers, directors, employees (the "Purchaser Indemnified Parties")
harmless from and against any and all Damages suffered by, imposed upon or
asserted against the Purchaser as a result of, in respect of, connected with or

  (a)         any failure of the Vendor to perform or fulfil any covenant of the

              delivered to the Purchaser pursuant to Section 6.1(a);

  (c)         the failure of the Parties to comply with any applicable bulk
              sales Laws in respect of the transaction of purchase and sale

  (d)         any liabilities of the Vendor and the Vendor Affiliates relating
              to the Purchased Business other than the Assumed Liabilities.

Section 7.3   Indemnification in Favour of the Vendor and the Vendor Affiliates.

       Subject to Section 7.4, the Purchaser shall indemnify and save the
Vendor, the Vendor Affiliates and each of their respective officers, directors

        (b)     any breach of any representation or warranty given by the

                certificate delivered to the Vendor pursuant to Section 6.2(a);

        (c)     the Assumed Liabilities; or

        (d)     any costs or liabilities arising from claims or assertions

                any failure by the Purchaser to extend offers of employment
                to the Employees set out in Schedule 1.1(jj).

Section 7.4     Limitations on Indemnification.

(1)     Except for claims made under Section 7.2 in respect of Section 4.1(e)
        (No Other Agreements to Purchase) and Section 4.1(f) (Title to
        Purchased Assets) no claim for indemnification shall be made by any
        Purchaser Indemnified Party pursuant to Section 7.2(a) or Section
        7.2(b) until the total amount of all Damages with respect to such
        matters exceeds $350,000 and then only for the amount by which such
        Damages exceed $350,000 up to a maximum of 33% of the Purchase Price.

(2)     Except for any claims made under Section 7.3 in respect of Section
        5.13, no claim for indemnification shall be made by any Vendor
        Indemnified Party pursuant to Section 7.3(a) and Section 7.3(b) until
        the total amount of all Damages with respect to such matters exceeds
        $350,000 and then only for the amount by which such Damages exceed
        $350,000 up to a maximum of 33% of the Purchase Price.

Section 7.5     Procedure for Indemnification - Other Claims.

        A claim for indemnification for any matter not involving a third-party
claim may be asserted by notice to the Party from whom indemnification is sought
in accordance with this Agreement.

Section 7.6     Indemnification Proceedings - Third Party Claims.

(1)     Promptly after receipt by the party seeking indemnification (the
        "Indemnified Party") of a notice of any action, proceeding, claim or
        potential claim ("Circumstance") against it by a third party that could
        give rise to a right of indemnification under Section 7.2 or Section
        7.3, the Indemnified Party will, if a claim is to be made against the
        party who may become obligated to provide indemnification hereunder
        (the "Indemnifying Party"), give written notice to the Indemnifying
        Party describing the Circumstance in reasonable detail. The failure to
        notify the Indemnifying Party will not relieve the Indemnifying Party
        of any liability that it may have to any Indemnified Party, except to
        the extent that the Indemnifying Party


                                       -67-

         demonstrates that the defence of such action is actually prejudiced by\
         the Indemnified Party's failure to give such notice.

(2)      If any proceeding referred to in Section 7.6(1) (a "Proceeding") is
         brought against an Indemnified Party and it gives notice to the
         Indemnifying Party of the commencement of the Proceeding, the
         Indemnifying Party will be entitled to participate in the Proceeding as
         hereinafter provided. Subject to the next following sentence, to the
         extent that the Indemnifying Party wishes to assume the defence of the
         Proceeding with counsel satisfactory to the Indemnified Party, it may
         do so provided it reimburses the Indemnified Party for all of its
         out-of-pocket expenses (including solicitor's fees and disbursements)
         arising prior to or in connection with such assumption. The
         Indemnifying Party may not assume defence of the Proceeding if: (i) the
         Indemnifying Party is also a party to the Proceeding and the
         Indemnified Party determines in good faith that joint representation
         would be inappropriate; or (ii) the Indemnifying Party fails to provide
         reasonable assurance to the Indemnified Party of its financial capacity
         to defend the Proceeding and provide indemnification with respect to
         the Proceeding. After notice from the Indemnifying Party to the
         Indemnified Party of its election to assume the defence of the
         Proceeding as against the Indemnified Party, the Indemnifying Party
         will not, as long as it diligently conducts such defence, be liable to
         the Indemnified Party under this Section 7.6 for any fees of other
         counsel or any other expenses with respect to the defence of the
         Proceeding, in each case subsequently incurred by the Indemnified Party
         in connection with the defence of the Proceeding, other than reasonable
         costs of investigation approved in advance by the Indemnifying Party.
         If the Indemnifying Party assumes the defence of a Proceeding as
         against the Indemnified Party (A) it will be conclusively established
         for purposes of this Agreement that the claims made in that Proceeding
         are within the scope of, and subject to, indemnification, (B) no
         compromise or settlement of such claims may be made by the Indemnifying
         Party without the Indemnified Party's consent unless (y) there is no
         admission of any violation of Laws or any violation of the rights of
         any Person and no adverse effect on any other claims that may be made
         against the Indemnified Party, and (z) the sole relief provided is
         monetary damages that are paid in full by the Indemnifying Party, and
         (C) the Indemnified Party will have no liability with respect to any
         compromise or settlement of such claims effected without its consent.
         If notice is given to an Indemnifying Party of the commencement of any
         Proceeding and the Indemnifying Party does not, within ten (10) days
         after receipt of such notice, give notice to the Indemnified Party of
         its election to assume the defence of the Proceeding, the Indemnifying
         Party will be bound by any determination made in the Proceeding or any
         compromise or settlement effected by the Indemnified Party acting in
         good faith.


                                       -68-

(3)   Notwithstanding the foregoing, if an Indemnified Party determines in
      good faith that there is a reasonable probability that a Proceeding may
      adversely affect it or any of its Affiliates other than as a result of
      monetary damages for which it would be entitled to indemnification
      under this Agreement, the Indemnified Party may, by notice of the
      Indemnifying Party, assume the exclusive right to defend, compromise,
      or settle the Proceeding. In such case, the Indemnifying Party will not
      be bound by any compromise or settlement effected without its consent
      (which may not be unreasonably withheld) but shall be bound by a final
      and conclusive judgement of a court of competent jurisdiction.

(4)   Where the defence of a Proceeding is being undertaken and controlled by
      the Indemnifying Party, the Indemnified Party will use its Best Efforts
      to make available to the Indemnifying Party those employees whose
      assistance, testimony or presence is necessary to assist the
      Indemnifying Party in evaluating and defending any such claims.
      However, the Indemnifying Party shall be responsible for the expense
      associated with any employees made available by the Indemnified Party
      to the Indemnifying Party pursuant to this Section 7.6(4), which
      expense shall be equal to an amount to be mutually agreed upon per
      person per hour or per day for each day or portion thereof that the
      employees are assisting the Indemnifying Party and which expenses shall
      not exceed the actual cost to the Indemnified Party associated with the
      employees.

(5)   With respect to any Proceeding at the request of the Indemnifying
      Party, the Indemnified Party shall make available to the Indemnifying
      Party or its representatives on a timely basis all documents, records
      and other materials in the possession of the Indemnified Party, at the
      expense of the Indemnifying Party, reasonably required by the
      Indemnifying Party for its use in defending any such claim and shall
      otherwise cooperate on a timely basis with the Indemnifying Party in
      the defence of such claim.

(6)   With respect to any Proceeding in respect of Taxes enforceable by
      Encumbrance against the property of the Indemnified Party, the
      Indemnifying Party's right to so defend the Proceeding shall only apply
      after payment of the re-assessment.

Section 7.7   Exclusion of Other Remedies.

(1)   From and after the Closing Date, no Party shall have the right to bring
      any proceeding against any other Party for a breach of any
      representation, warranty, covenant or agreement contained in this
      Agreement or any other Transaction Document whether in contract, tort
      or otherwise, except pursuant to Section 7.1, Section 7.2 and Section
      7.3.


                                       -69-

(2)    Notwithstanding anything in this Agreement to the contrary, the
       liability of any party under Article 7 shall be in addition to, and not
       exclusive of, any other liability that such party may have at law or
       equity based on such party's fraudulent acts or omissions. None of the
       provisions set forth in this Agreement, including the provisions set
       forth in Section 7.2 or Section 7.3, shall be deemed a waiver by any
       party to this Agreement of any right or remedy which such party may
       have at law or equity based on any other party's fraudulent acts or
       omissions, nor shall any such provisions limit, or be deemed to limit,
       (a) the amounts of recovery sought or awarded in any such claim for
       fraud, (b) the time period during which a claim for fraud may be
       brought, or (c) the recourse which any such party may seek against
       another party with respect to a claim for fraud; provided, that with
       respect to such rights and remedies at law or equity, the parties
       further acknowledge and agree that none of the provisions of this
       Section 7.7, nor any reference to this Section 7.7 throughout this
       Agreement, shall be deemed a waiver of any defences which may be
       available in respect of actions or claims for fraud including defences
       of statutes of limitations or limitations of damages.

                                    ARTICLE 8

               shall not be available to any Party whose failure to fulfil any
               covenant or obligation under this Agreement shall have been the
               cause of, or shall have resulted in, the failure of the Closing
               to occur on or prior to the Outside Date;

   (c)         by the Purchaser in the event a condition set forth in Section

of the Parties shall issue any press release or make any other public statement
or announcement relating to or connected with or arising out of this Agreement
or the matters contained herein, without obtaining the prior written approval of
the others, to the contents and the manner of presentation and publication
thereof. If disclosure is required by Law or the requirements of any stock

day on which final judgement is given or, if permitted by applicable Law, on the
day in which the judgement is paid or satisfied.

Section 8.16   Guarantee.

months following Closing. This guarantee shall be a continuing and irrevocable
guarantee and shall survive the Closing indefinitely. Without limitation, the
obligations of this guarantee shall not be released, discharged or affected by
any extensions of time or indulgences or modifications granted by the Vendor in
favour of the Purchaser, or by any failure to enforce any of the terms of this
Agreement or by the bankruptcy, insolvency, dissolution, amalgamation,
winding-up or reorganization of the Purchaser and the Guarantor hereby waives
any right to require the Vendor to exhaust any action or recourse against the
Purchaser before requiring performance by the Guarantor pursuant to this

Parties to consummate the transactions contemplated by this Agreement.

pertaining to the subject matter hereof and supersedes all prior and
intermediate agreements, understandings, negotiations and discussions, whether

     thereby.

(2)  No failure on the part of the Vendor or the Purchaser to exercise, and no
     delay in exercising any right under this Agreement shall operate as a

     preclude any other or further exercise of any other right.

     This Agreement shall be governed by and interpreted and enforced in
accordance with the laws of the Province of Ontario and the laws of Canada
