SECTION 2. GOALS AND OBJECTIVES AND ROLE OF BELL
2.1   The Parties have entered into this Agreement on the basis of the following
      goals and objectives, subject to the provisions of this Agreement:
      a.    Transfer on Effective Date. As of the Effective Date, the BCH
            Companies at their cost and expense transferred to Certen (i) all
            Systems, assets, documents and materials relating to the Legacy
            Systems, which were the same or substantially the same Systems,
            assets, documents and materials relating to the Legacy Systems, as
            applicable, used by the BCH Companies immediately prior to the
            Effective Date, and that were materially required and relevant in
            order for Certen to provide the Services and perform its other
            obligations under this Agreement with respect to the Legacy Systems;
            provided, however, that if any Required Consents not obtained by
            Bell prevented full compliance with the foregoing, Section 4 below
            shall apply and (ii) the human resources required for Certen to
            continue to provide with respect to the Legacy Systems the Services
            which were provided immediately prior to the Effective Date.
      b.    Services and Service Levels for Legacy Systems Generally. Except as
            otherwise expressly provided in this Agreement (including any
            Exhibit hereto), Certen shall, from and after the Effective Date,
            provide all the Services and meet the Service Levels and all other
            obligations with respect to such Services and Service Levels with
            respect to the Legacy Systems, [**] manner as the services, service
            levels, and other obligations, as applicable, [**] by the BCH
            Companies [**] to the Effective Date.
      c.    Modernization Generally. Certen shall, as contemplated under this
            Agreement and the Master License and Services Agreement, continue to
            work with Amdocs to develop and provide to the BCH Companies the
            Modernized Systems, the
                                       13
            whole in accordance with the 2003 Road Map including any timelines
            set forth therein, and the BCH Companies shall continue to take the
            necessary steps to implement the Modernization in accordance with
            the 2003 Road Map. The BCH Companies may not cease the performance
            of their obligations relating to the implementation of the 2003 Road
            Map until the budget for the 2003 Road Map as set forth in Exhibit D
            has been fully utilized.
      d.    Billing Laboratory. As part of the Modernization process, Certen
            will establish, if Bell so requests, a permanent "billing
            laboratory" to provide "best in class" Service Levels and to test
            enhanced billing solutions, capabilities and associated software,
            thereby enabling the greatest customization of billing solutions for
            the BCH Companies.
      e.    Results of Modernization. As a result of Modernization, Certen will
            improve the then [**] provided to the BCH Companies and enhance
            access by the BCH Companies to leading information technology
            industry and processes.
      f.    Realization of Cost Savings and Efficiencies. Following the
            Modernization, Certen will enable the BCH Companies to more rapidly
            achieve ongoing cost savings and efficiencies to be realized
            together with enhanced capabilities in accordance with this
            Agreement. The BCH Companies will Cooperate with Certen to assist
            Certen in achieving efficiencies, where applicable.
      g.    Improvements to Quality and Cost Effectiveness. Following the
            Modernization, Certen will improve the quality and cost
            effectiveness of the Services provided to the BCH Companies by
            Certen.
      h.    Use of Internet Technology. Certen will interface and communicate
            with the BCH Companies using Internet technology, such as e-mail, in
            line with the BCH Companies' "web enabled" general goal and
            objective.
      i.    Role of Bell - Post Amendment Effective Date - Generally. From and
            after the Amendment Effective Date, the Parties intend that Bell
            shall be responsible for (i) overall project management; (ii)
            overall business and technical architecture; (iii) the business
            analyst function related to ensuring that the BCH Companies'
            requirements for the Systems are met; (iv) user acceptance testing
            and business unit acceptance testing, and (v) oversight of
            management of billing operations, all as set forth under the heading
            "Bell" in Exhibit O-1 and Exhibit O-2.
      j.    Scope of Services Generally. The Parties acknowledge that the
            relationship memorialized by this Agreement is dynamic in nature and
            that such relationship will change, as the operating and business
            environment of the BCH Companies shall also change, and that it is
            impossible to define with absolute specificity the scope of the
            Services that will be provided by Certen during the Term of this
            Agreement. The Parties therefore agree that the scope of the
            Services with respect to the Legacy Systems shall at all relevant
            times be consistent with Section 2.1a, 2.1b and 2.1i above, and that
            the scope of the Services with respect to the Systems
                                       14
            after Modernization shall at all relevant times be consistent with
            Sections 2.1c to 2.1i, inclusive.
2.2   BELL TO REPRESENT BCH COMPANIES. The Parties recognize and agree that the
      BCH Companies shall receive the Services from Certen in accordance with
      the terms and conditions of this Agreement. It is further agreed that ▇▇▇▇
      Canada, as Party to this Agreement, shall be the interface between Certen
      and the BCH Companies (i.e., acting on ▇▇▇▇ Canada's own behalf and for
      the other BCH Company). Notwithstanding anything else to the contrary in
      this Agreement, ▇▇▇▇ Mobility shall have no right to make any Claim
      hereunder against Certen, except through Bell, including but not limited
      to, any Claim as third party beneficiary, provided however, that any Claim
      that ▇▇▇▇ Mobility may have hereunder shall be deemed to be a Claim of
      Bell.
2.3   BELL RESPONSIBLE AND LIABLE FOR [**]. In addition, Bell hereby undertakes
      throughout the Term and any extension thereof, as well as during any
      Transition-Out Period, to perform, and be liable for any breach or
      non-performance of, the obligations, representations, warranties, and
      indemnities [**] under this Agreement. This Section 2.3 shall survive
      termination or expiration of this Agreement, in accordance with the
      provisions of Section 33.1.
2.4   DIVESTITURE OF BCH COMPANY. In the event that Bell considers the
      divestiture of any one of the BCH Companies, Bell shall, on a reasonable
      commercial efforts basis, request that the potential purchaser of the
      divested entity respect the [**] and [**] provisions set forth in Section
      6 below; provided, however, that the foregoing shall not in any way
      relieve Bell or derogate from ▇▇▇▇'▇ undertakings under this Agreement
      including, but not limited to, the obligations set forth in Section 6
      below. Notwithstanding the foregoing, if Bell divests a BCH Company (or
      effects any reorganization) or a business unit (or any part thereof) or a
      Line of Business of a BCH Company to an Affiliate of Bell, Bell shall
      remain bound by the [**] and [**] provisions set forth in Section 6 below
      with respect to such BCH Company, business unit (or any part thereof) or
      Line of Business. Bell will take all necessary action to ensure that such
      Affiliate complies with all the terms of this Agreement with respect to
      such BCH Company, business unit (or any part thereof) or Line of Business.

Initial Term for an additional three (3) year extension period (the Initial Term
together with such three (3) year extension period (if such is agreed to by

SECTION 4. REQUIRED CONSENTS
Unless otherwise mutually agreed between the Parties, the responsibility for
Required Consents shall be as follows:
4.1   BCH COMPANIES TO OBTAIN REQUIRED CONSENTS. The BCH Companies will obtain
      the Required Consents which have not previously been obtained prior to the
      Effective Date and will have responsibility for all communications seeking
      the Required Consents. Unless otherwise mutually agreed, [**]
      responsibility for any payments required to obtain the Required Consents.
      If any Required Consent was not or is not obtained with respect to any
      lease, license, service or other agreement (or if the Required Consent so
      obtained by ▇▇▇▇ contains additional terms or conditions, which in
      Certen's good faith opinion would have an adverse affect on its business),
      then [**] any such lease, license, service, or other agreements and the
      rights thereunder in trust for the benefit of Certen and promptly so
      notify Certen, and unless and until that Required Consent is obtained, the
      BCH Companies shall promptly provide, with Cooperation from Certen, an
      alternative arrangement [**] for
                                       17
      transferring to Certen, as of the Effective Date, the same or
      substantially the same benefits, space, amenities, utilities,
      functionalities, usefulness, levels of service and obligations, as
      applicable, under the lease, license, service or other agreement for which
      the Required Consent was not obtained. Without limiting Certen's other
      remedies under this Agreement, in the event that the failure to obtain any
      Required Consent results in the failure of Certen to comply with any of
      its obligations under this Agreement, then Certen shall be excused from
      such obligations.
4.2   ▇▇▇▇ TO INDEMNIFY CERTEN FOR FAILURE TO OBTAIN REQUIRED CONSENT. With
      respect to any Losses arising from any failure to obtain any Required
      Consent, ▇▇▇▇ shall indemnify and hold harmless Certen pursuant to Section
      17.3b hereof. However, if ▇▇▇▇ expressly and specifically notifies Certen
      in advance and in writing of the BCH Companies' failure to obtain a
      certain Required Consent, and Certen knowingly and willfully uses any
      applicable space, equipment, software or third party services dependent on
      such unobtained Required Consent, ▇▇▇▇ shall not be obligated to indemnify
      or hold Certen harmless from any third party claim to the extent such
      claim is directly related to such use.
4.3   CONTRACTS OF BCH COMPANIES ASSIGNED TO CERTEN.
      a.    Assumption of Certain BCH Company Contracts. Subject to Section 5.1
            of this Agreement, Certen agrees to assume all rights and
            obligations of the BCH Companies arising from the assignment
            hereunder of leases, software licenses, maintenance and equipment

            contracts solely related to the Services, to Certen on or after the
            Effective Date. A number of such assigned leases, licenses and
            contract are listed in ▇▇▇▇▇▇▇▇ ▇▇, ▇▇, and M3. In the case of the
            contracts listed in Exhibit M2, such contracts shall continue to be
            [**] and be subject to the applicable terms and conditions of the
            [**] Agreements.
      ▇.    ▇▇▇▇ to Provide Assistance. In the event that the Change in Control
            of Certen as of the Amendment Effective Date results in a
            termination of a contract which was assigned to Certen (as described
            in Section 4.3a above), or a modification thereto which has a
            material adverse affect on Certen, ▇▇▇▇ undertakes to make good
            faith efforts, through its existing relationship with the applicable
            lessor, supplier or vendor, to assist Certen in its negotiation to
            remain a party to such agreement on the same or substantially the
            same terms as those in effect prior to the Amendment Effective Date.
      c.    Changes to Assigned Contracts. Certen shall make reasonable efforts
            to provide ▇▇▇▇ with written notice prior to Certen's termination or
            material modification of any such assigned third party contracts. In
            addition, Certen shall indemnify and reimburse ▇▇▇▇ for any claims,
            charges or penalties incurred by the BCH Companies with respect to
            such assigned third party contracts to the extent such claims,
            charges or penalties (excluding losses of volume discount benefiting
            ▇▇▇▇) are caused by Certen and do not arise out of any event, act or
            omission taking place prior to the Effective Date.

      a.    Access to BCH Corporate Contracts. Subject to Section 5.12 below
            with respect to the [**] Agreement and the [**] Agreement, the
            Parties acknowledge that the BCH Companies are parties to certain
            corporate contracts (a number of which with respect to ▇▇▇▇ and ▇▇▇▇
            Mobility are listed in Exhibit L1) that relate to the Services but
            were not assigned by the BCH Companies to Certen, the scope of such
            contracts being greater than the scope of this Agreement. The BCH
            Companies shall exercise any and all rights they may have under such
            corporate contracts to enable Certen to fully benefit, as of the
            Amendment Effective Date (or promptly thereafter), from such
            corporate contracts until December 31, 2007, or such other period
            with respect to each contract as the Parties may agree ("BENEFIT
            PERIOD"). For corporate contracts identified in Exhibit L1 as
            material, at the BCH Companies' sole cost and expense, the BCH
            Companies agree to negotiate with the applicable third party the
            possibility for Certen to benefit from any and all such corporate
            contracts until the end of the Benefit Period. The benefits extended
            to Certen by ▇▇▇▇ hereunder shall only be used in its provision of
            the Services to ▇▇▇▇ under this Agreement.
      ▇.    ▇▇▇▇ to Assist Certen to Replace Contracts. Without limiting
            Certen's other remedies under this Agreement, in the event that the
            BCH Companies' failure to enable Certen to fully benefit from such
            material corporate contracts, as identified in Exhibit L1 (or
            comparable arrangements as aforesaid) until the end of the Benefit
            Period, results in the failure of Certen to comply with any of its
            obligations under this Agreement, then Certen shall be excused from
            such obligations. In addition, ▇▇▇▇ shall [**] enjoyed by Certen
            under such material corporate contract as at the Amendment Effective
            Date, despite reasonable efforts made by ▇▇▇▇ and Certen to [**]
            (including, without limitation, initiation fees, increase in license
            fee costs, or otherwise) until the end of the Benefit Period, but
            [**].
      c.    Certen May Terminate Rights Under Corporate Contracts. In order to
            benefit from any such corporate contracts (or comparable
            arrangements, as aforesaid), Certen shall respect any contractual
            obligations that may be imposed by the applicable third party until
            the end of the Benefit Period. For the avoidance of doubt, Certen
            shall not be obligated to continue to benefit under such corporate
            contracts (or alternative arrangements, as applicable), to maintain
            (or to compensate the BCH Companies for not maintaining) any [**]
            from which the BCH Companies may benefit as a result of operations
            of the BCH Companies that are outside the scope of the Agreement. In
            the event that Certen elects at any time not to continue to benefit
            under any of such corporate contracts, Certen agrees that it shall
            be responsible for all liabilities in connection with Certen
            entering into a new contract.
4.5   SERVICES TO BE PROVIDED BY BCH COMPANIES TO CERTEN. In order to enable
      Certen to provide the Services, the BCH Companies shall provide as of the
      Amendment Effective Date and continue to provide to Certen the services
      listed in Exhibit L2 under the terms
                                       19
      and conditions set out in such Exhibit. The BCH Companies shall make such
      services available to Certen for the Benefit Period, unless otherwise
      specified in Exhibit L2; provided, however, that Certen shall be entitled
      to cancel such services, in whole or in part, on reasonable written notice
      to the BCH Companies, the length of such reasonable notice to be agreed to
      between the Parties but which shall in no event be greater than the lesser
      of (a) [**] or (b) the time remaining in the applicable [**] pertaining to
      the service being terminated by Certen, and provided that ▇▇▇▇ reasonably
      demonstrates to Certen that ▇▇▇▇ is committed under the applicable service
      contract in such a way that a termination could reasonably be expected to
      have a material adverse commercial effect on the contract or on ▇▇▇▇'▇
      relationship with the third party thereunder. Absent such a showing by
      ▇▇▇▇, the termination notice shall be reasonable, but in no event greater
      than [**]. In addition, Certen agrees that ▇▇▇▇ shall be its [**] supplier
      of telecommunications services during the Term, subject to agreement on
      market rates for non-regulated services; regulated services shall be at
      applicable tariffed rates.
4.6   CERTEN MAY TERMINATE ASSIGNED CONTRACTS. From and after the Effective
      Date: (a) Certen shall be responsible for paying the lessors, vendors and
      suppliers listed in Exhibits L1 for the services or other benefits
      received by Certen thereunder; and (b) Certen shall be responsible for
      making any required payments and to fulfil its other obligations under the
      contracts listed in Exhibits M1 and M2. Subject to its obligations to pay
      applicable penalties, damages, termination or other charges, Certen may
      cancel, substitute or change the lessors, vendors or suppliers (or
      terminate the benefits that Certen is receiving) under the third party
      agreements under Exhibit L1, M1 and M2 as it chooses, in which case,
      Certen shall continue to perform the Services in the manner required by
      this Agreement. Certen will make reasonable efforts to provide written
      notification to the BCH Companies prior to the termination or modification
      of any such third party agreement (or termination of the benefit that
      Certen is receiving, as applicable) as well as in the event such
      termination may have an impact on the operations of the BCH Companies.
4.7   ▇▇▇▇ OBLIGATION TO REIMBURSE CERTEN. Subject to Exhibit J, upon
      termination or expiration of this Agreement, ▇▇▇▇ shall reimburse Certen
      in a timely manner for any payments made by Certen to the lessors, vendors
      and suppliers (whose leases, licenses or other agreements are transferred
      back to the BCH Companies in accordance with this Agreement) during the
      period prior to the effective date of such termination or expiration that
      would apply for any period subsequent to the termination or expiration
      date.
4.8   INDEMNITY FOR PRE-EFFECTIVE DATE EVENTS. ▇▇▇▇ shall remain solely liable
      for and shall indemnify Certen against any Claims arising out of any
      events, acts or omissions which took place prior to the Effective Date
      with respect to the contracts, leases, licenses and other agreements
      described in this Section 4.
4.9   COMPLETION OF EXHIBITS. The Parties recognize and agree that certain
      Exhibits remain incomplete as of the Amendment Effective Date, as
      expressly set forth in such Exhibits. The Parties will use all reasonable
      efforts to finalize incomplete Exhibits within the period set forth in
      such Exhibits for completion. Following the Amendment Effective Date, the
      Parties reserve the right to perform an inventory of, and validate and
      update,
                                       20
      any information that is reflected in or omitted from the attached Exhibits
      (in all cases, with the final Exhibit to be agreed in writing by the
      Parties).
SECTION 5. TRANSFER OF LEGACY SYSTEMS AND PROVISION OF SERVICES
5.1   TRANSFER OF LEGACY SYSTEMS. As of the Effective Date, the BCH Companies
      transferred, at their cost and expense as also specified in the Asset
      Transfer Agreement all of their right, title, and interest in and to (i)
      the Systems (including the Legacy Systems) and assets (and the
      Intellectual Property Rights therein set forth in ▇▇▇▇▇▇▇▇ ▇▇, ▇▇ and M3
      to the extent of the assigned contracts specified therein, and any other
      systems, assets, documents, or materials (and the Intellectual Property
      Rights therein) necessary and relevant for Certen to provide the Services
      with respect to the BCH Companies' Legacy Systems, which were the same or
      substantially the same Systems, assets, documents, or materials, as
      applicable, used by the BCH Companies immediately prior to the Effective
      Date; provided, however, that if any Required Consents not obtained by the
      BCH Companies prevent full compliance with the foregoing, Sections 4.1 and
      4.2 above shall apply and (ii) the human resources required for Certen to
      provide the Services with respect to the Legacy Systems, as such existed
      immediately prior to the Effective Date. Without limiting Certen's other
      remedies under this Agreement, in the event that the BCH Companies have
      failed to so deliver such Systems, assets, documents, materials or human
      resources, in whole or in part, as of the Effective Date, Certen shall be
      excused from its obligations with respect to the Legacy Systems, to the
      extent such undelivered Systems, assets, documents, materials or human
      resources are required to perform such obligations.
5.2   [**] SOFTWARE. ▇▇▇▇ granted, as of the Effective Date, to Certen a
      royalty-free, non-exclusive license (in object and source code) to use the
      [**] Software, with a right to sub-license, in the Territory (i) for the
      purpose of the delivery of the Services; and (ii) similar services to
      third parties, throughout the Term. Certen shall indemnify ▇▇▇▇ for any
      Claim for infringement of Intellectual Property Rights arising out of
      Certen's use of the [**] Software outside of the Territory.
5.3   OVERSIGHT FUNCTIONS TO BE PERFORMED BY ▇▇▇▇. From and after the Amendment
      Effective Date, ▇▇▇▇ shall assume the performance of the Oversight
      Functions.
5.4   CERTEN TO PROVIDE SERVICES TO BCH COMPANIES. ▇▇▇▇ hereby confirms, as of
      the Amendment Effective Date, that a substantial majority of the customers
      of the BCH Companies reside in the Territory. Certen shall continue to
      provide the Services to the BCH Companies, a substantial majority of the
      subscribers of which shall continue to be located within the Territory.
5.5   SERVICE LEVELS - LEGACY SYSTEMS. The Services and Service Levels provided
      by Certen with respect to the Legacy Systems, and all other obligations
      with respect to such Services and Service Levels, shall be [**] services,
      service levels, or other such obligation received by the BCH Companies
      [**], except to the extent expressly provided otherwise in this Agreement
      (including any Exhibit hereof).
                                       21
      a.    Accordingly, in the event that the BCH Companies request Certen to
            perform a service, service level or other obligation with respect to
            the Legacy Systems (collectively, the "SUPPLEMENTAL OBLIGATION")
            that:
            (i)   was not performed by/for the BCH Companies immediately prior
                  to the Effective Date;
            (ii)  is not otherwise expressly set forth in this Agreement
                  (including any Exhibit hereof); and
            (iii) (A) is not a fringe service, which is ancillary or
                  complimentary to Sections 5.5a(i) or 5.5a(ii) above, and (B)
                  the provision of such Supplemental Obligation would have no
                  material financial impact on Certen (provided, however, that
                  even if such Supplemental Obligation would have a material
                  financial impact on Certen, the Parties shall not consider
                  such impact (for purposes of this Section 5.5a) if Certen had
                  notice in writing from the BCH Companies of the performance of
                  such Supplemental Obligation through the disclosure of
                  materials provided by the BCH Companies during the due
                  diligence period prior to the Effective Date),
      then such request shall be deemed a Change Request.
      b.    Conversely, in the event that the BCH Companies request Certen to
            perform a Supplemental Obligation that:
            (i)   was performed by/for the BCH Companies immediately prior to
                  the Effective Date,
            (ii)  is otherwise expressly set forth in this Agreement (including
                  any Exhibit hereof); or
            (iii) is (A) a fringe service, which is ancillary or complimentary
                  to subsections 5.5a or 5.5b above and (B) the provision of the
                  Supplemental Obligation would have no material financial
                  impact on Certen or if Certen had notice of the performance of
                  such Supplemental Obligation through the disclosure of
                  materials provided by the BCH Companies during the due
                  diligence period prior to the Effective Date),
      then such request shall be performed by Certen as part of the Services
      (without additional charge).
5.6   SERVICE LEVELS - MODERNIZED SYSTEMS. Initially the Service Levels provided
      by Certen with respect to the Modernized Systems shall be [**] Systems.
      The Service Levels for the Modernized Systems shall be subject to upward
      adjustment after the Amendment Effective Date as agreed to by the Parties.
5.7   RESTRICTIONS ON CHANGES TO HARDWARE PLATFORM.
                                       22
      a.    Certen or ▇▇▇▇ will install at the Installation Site(s) the Platform
            as required for the installation and proper operation of the
            Products, in accordance with a detailed configuration to be mutually
            agreed upon by Certen and ▇▇▇▇ and to be specified in the DAD
            document or as set forth in the Roles and Responsibilities (as such
            capitalized terms used herein are defined in the Master License and
            Services Agreement). Certen shall not replace or modify the BCH
            Companies' Hardware platform unless new Hardware is compatible with
            the Hardware platform used by the BCH Companies in their other
            operations. In addition, Certen will purchase new Hardware, Software
            and network resources, as required pursuant to the 2003 Road Map,
            and as set forth in the applicable detailed architectural design
            document in order to successfully complete the Modernization. The
            BCH Companies acknowledge and agree that Certen plans to utilize a
            [**] environment of one of the leading [**] suppliers.
      b.    For Systems required to perform the Services, Certen shall maintain
            Currency for (i) the Licensed Products (as defined in the Master
            License and Services Agreement) incorporated into the Modernized
            System, (ii) third party Software used to provide the Services, and
            (iii) Hardware. In this Agreement, "CURRENCY" or "CURRENT" means
            that the Software and Hardware versions are [**] the applicable
            vendor (in the case of the Licensed Products incorporated into the
            Modernized System, by Certen's (or its Affiliate's) research and
            development division). Notwithstanding the foregoing, if any
            Software or Hardware components are not Current as of the Amendment
            Effective Date, then Certen shall not have any obligation of
            Currency for such components for the period of [**] from the
            Amendment Effective Date. Certen will manage the incorporation of
            upgrades and enhancements in accordance with Certen's business
            practices which shall be comparable with those of leading suppliers
            of managed operations services in North America. Certen will
            consider recommendations from ▇▇▇▇ regarding the implementation of
            updates and enhancements.
      c.    Software other than: (i) Software that is readily commercially
            available from a Person which is not an Affiliate of Certen; or (ii)
            Software in respect of which Certen or Amdocs has granted ▇▇▇▇ a
            [**] license pursuant to the MLSA, may only be used to provide the
            Services in accordance with a Change Proposal pursuant to which ▇▇▇▇
            is entitled to obtain a [**] license, under the terms provided for
            in the MLSA, to use such Software.
5.8   DATA BACKUP STORAGE SERVICES. Certen shall be responsible for data backup
      storage services with respect to the Databases.
5.9   THIRD PARTY DEVELOPMENT SUPPORT SERVICES. If requested by ▇▇▇▇, Certen
      will perform Third Party Development Support Services, which shall be
      charged for [**] in accordance with Exhibit ▇. ▇▇▇▇ shall, before
      obtaining any Development Work (including Software) from a third party for
      operation on the Systems, consult with Certen concerning the integration
      of such Development Work on the Systems. Certen has the right to test and
      approve any Development Work of a third party provider prior to the
      integration thereof on the Systems. Certen shall cooperate with any third
      party provider
                                       23
      of such Development Work and shall provide any information reasonably
      required by the third party in connection with the development, testing,
      configuration or implementation of such Development Work for use on the
      Systems and shall integrate the third party Development Work for operation
      on the Systems on the terms set forth herein. Where ▇▇▇▇ requires Certen
      to work with a third party developer, then unless otherwise agreed in
      writing, Certen will not be responsible for disruption to or negative
      impact on the provision of the Services by Certen which results from
      defects in the Development Work provided by such third party developer.
      Certen shall promptly notify ▇▇▇▇ of any defects in the Development Work
      performed by the third party of which Certen is aware.
5.10  DISASTER RECOVERY SERVICES. Certen shall, as part of the Services, provide
      disaster recovery services as contemplated by Exhibit I hereto. The
      Parties agree to share the reasonable and necessary initial setup costs
      required for the implementation of the DRPs, the ARMs and the BCRPs (as
      defined in Exhibit I) (e.g., Hardware, Software, facilities, installation,
      etc.) which the Parties had reasonably expected to have been in place on
      the Amendment Effective Date as follows: [**]% by ▇▇▇▇ and [**]% by
      Certen. Following the initial setup of the Systems as required to
      implement such DRPs, ARMs and BCRPs, Certen will bear the costs associated
      with adapting and maintaining the Systems and such DRPs, ARMs and BCRPs
      and providing any related Services for the Modernized System during the
      Term.
5.11  COMPLIANCE REQUIREMENTS DISCOVERED DURING AUDIT. Pursuant to Section 23.3,
      the Parties acknowledge that certain Services that Certen is required to
      provide under the Amended MOSA, or is otherwise required by law to
      provide, may not have been so provided as of the Amendment Effective Date
      (such deficiencies being those listed in Exhibit W and any deficiencies
      identified in any audits pursuant to Section 23.3 hereof relating to
      events which occurred prior to the Amendment Effective Date and which are
      identified in any audit conducted in accordance with Section 23.3 prior to
      the Amendment Effective Date or in any audit conducted in accordance with
      an Audit Plan during the period of [**] months from the Amendment
      Effective Date (the "AUDIT DEFICIENCIES"). The Parties agree to work
      together to correct the Audit Deficiencies as cost-efficiently as possible
      and agree that the necessary costs reasonably incurred, which shall be
      agreed upon in advance by the Parties, to upgrade the Systems to the
      extent required to permit Certen to correct the Audit [**] shall be paid
      as follows: [**]% by ▇▇▇▇ and [**]% by Certen. After the Systems have been
      upgraded as provided above, [**] will bear all of the costs associated
      with providing the Services and adapting and maintaining the Systems as
      required to continue to provide such Services thereafter during the Term.
5.12  CERTEN TO COOPERATE WITH OTHER SERVICE PROVIDERS.
      a.    Certen to Cooperate with Other Service Providers. Certen shall
            reasonably cooperate with other service providers providing services
            related to the Services, such as but not limited to [**] and [**],
            subject to Certen's confidentiality requirements (including special
            arrangements with third party competitors of Amdocs), in accordance
            with Section 16 below, and subject to ▇▇▇▇'▇ reimbursement of
            Certen's reasonable costs resulting from such cooperation,
                                       24
            which costs for greater certainty shall not include any costs
            resulting from cooperation with Amdocs or any Affiliate of Amdocs or
            Certen.
      b.    [**] Agreement. In order to enable Certen to benefit from the
            provision of [**] services under the [**] Agreement, as such
            services relate to the Services, the BCH Companies designate Certen
            as an Authorized User under the [**] Agreement, as defined therein,
            and Certen accepts such designation. Certen, by accepting such
            designation, agrees to be bound by all applicable terms and
            conditions of the [**] Agreement with the exception of [**]. The
            Parties also agree that fees related to Certen's receipt of [**]
            services under the [**] Agreement shall be payable by Certen to
            ▇▇▇▇, and such fees shall be expressed for the [**] in terms of
            [**], and on [**] for the [**] as per the terms and conditions of
            the [**] Agreement. ▇▇▇▇ acknowledges that its fees to [**] for the
            full calendar year 2002, for that portion of the [**] services to
            ▇▇▇▇ which relate to the Services were [**] Canadian Dollars
            (CA$[**]). Certen's projected fees in 2003 are [**] Canadian Dollars
            (CA$[**]) and the projected price for such [**] is $[**] Canadian
            Dollars (CA$[**]) per [**]. Notwithstanding the foregoing, if the
            fees related to Certen's receipt of [**] services materially exceed
            the fees budgeted in the Business Case to be paid for such services
            (other than for reasons attributable to the existing pricing regime
            under the [**] Agreement), the Parties will negotiate in good faith
            a solution to counter such increased cost. Furthermore Certen agrees
            to indemnify ▇▇▇▇ in the event of any failure by Certen to comply
            with the applicable terms and conditions of the [**] Agreement ([**]
            for greater certainty any [**] obligations contained therein).
      c.    [**] Agreements. In order to enable Certen to benefit from the
            provision of [**] services under the ▇▇▇▇-[**] Agreement and under
            the ▇▇▇▇-Mobility-[**] Agreement, as such services relate to the
            Services (the "▇▇▇▇-[**] SERVICES" and the "▇▇▇▇ MOBILITY-[**]
            SERVICES", respectively; collectively, the "[**] SERVICES"), ▇▇▇▇
            designates Certen as [**] under the [**] Agreements, as applicable
            and as defined therein, and Certen accepts such designation. ▇▇▇▇
            represents that its fees to [**] for the full calendar year 2002 for
            that portion of the [**] Services [**] fees to ▇▇▇▇ which relate to
            the Services were [**] Canadian Dollars (CA$[**]) ("▇▇▇▇'▇ [**]
            FEES"). ▇▇▇▇'▇ [**] Fees projected for 2003 are [**] Canadian
            Dollars (CA$[**]). The Parties agree that the fees related to
            Certen's receipt of the Bell-[**] Services provided to Certen shall
            be payable by Certen to Bell and such fees shall be not greater than
            the fees paid by Bell to [**] for such Services. Notwithstanding the
            foregoing, in the event that ▇▇▇▇'▇ [**] Fees payable by Certen
            materially increase, other than for reasons attributable to the
            existing pricing regime under the Bell-[**] Agreement, the Parties
            shall negotiate in good faith a mutually acceptable solution to
            counter such increased cost and the same shall apply, mutatis
            mutandis, to the fees with respect to the ▇▇▇▇ Mobility-[**]
            Services. Certen shall [**], as [**] under the [**] Agreements, to
            any right [**] granted by Bell or ▇▇▇▇ Mobility to [**]
            (collectively, "BCH [**] OBLIGATIONS") and to which the BCH
            Companies are, therefore, subject under the [**] Agreements, but
            Certen acknowledges that it will receive the Bell-[**] Services and
            the ▇▇▇▇ Mobility [**] Services referred to herein. Furthermore,
                                       25
            the BCH Companies [**] to do all things and take all actions which
            the BCH Companies are entitled to do and take under the [**]
            Agreements, including liaising directly with [**], in relation to
            the services of [**] which Certen receives as [**], and Certen
            accepts such appointment. Certen, by accepting such designation and
            appointment agrees to be bound by the applicable terms and
            conditions of the [**] Agreements, but (for the avoidance of doubt)
            [**] by the BCH [**] Obligations. In addition, Certen shall have the
            duty to interact directly with [**] in relation to day-to-day
            matters such as work program content, [**] related to the services
            Certen shall receive from [**], all as indicated in the [**]
            Agreements, and to manage its relationship with [**] as it relates
            to the Services. The BCH Companies shall have the right to
            reasonably monitor interfaces between Certen and [**]. Certen agrees
            to indemnify the BCH Companies in the event of any Claim by [**]
            against the BCH Companies arising out of Certen's material breach of
            its obligation as [**] under the [**] Agreements. For the avoidance
            of doubt, Certen [**] Bell in the event of any Claim or Losses
            arising out of the BCH [**] Obligations or any BCH Company
            obligations to meet (or benefits to the BCH Companies for meeting)
            [**] under the [**] Agreements.
      d.    Orders to [**] or [**]. The Parties agree that the BCH Companies
            shall not issue any order to [**] or [**] (including but not limited
            to any order issued in connection with the annual work plans with
            such companies) for which Certen would be liable without the prior
            written consent of Certen, which consent shall not be unreasonably
            withheld.
      e.    Effect of Breach of Agreements. If [**] breaches the [**] Agreements
            or [**] breaches the [**] Agreement, (i) the BCH Companies' remedies
            with regard to such breach(es) shall be as set forth in such
            agreements; and (ii) Certen's responsibilities with respect to such
            breaches shall be limited to its obligations to manage and direct
            the [**] Agreements, as the BCH Companies' [**], and to act in
            accordance with the obligations of [**] under both the [**]
            Agreements and the [**] Agreement and Certen shall have no other
            liability to the BCH Companies for breaches by [**] of the [**]
            Agreements or for breaches by [**] of the [**] Agreement.
      f.    Modification of Certain Corporate Contracts. Notwithstanding
            anything to the contrary, the BCH Companies shall have no right to
            modify, waive or terminate any rights in any material corporate
            contracts identified in Exhibit L1 (including but not limited to the
            [**] Agreement and the [**] Agreements) without Certen's prior
            written consent therefor, if such extension or modification would
            have a material adverse affect on the business of Certen.
      g.    [**] and [**] Agreements. Certen acknowledges that [**] the [**]
            Agreements and the [**] Agreements [**] prior to the entering into
            of this Agreement. In the event that the BCH Companies have [**] of
            the [**] Agreements or [**] Agreement and [**] has a [**] on the
            business of Certen, the BCH Companies shall indemnify and hold
            Certen harmless against any Losses suffered by it as a result of
            [**].
                                       26
5.13  USE OF INTERNET TECHNOLOGY. Certen shall make reasonable efforts to
      interface and communicate with the BCH Companies using Internet
      technology, such as e-mail, as the primary technology platform for such
      interfacing and communication, where applicable, e.g., for the processing
      and payment of invoices between the Parties.
5.14  SERVICE DELIVERY [**]. Without derogating from any other rights of Certen
      hereunder, Certen shall have the option to (a) [**] the system
      administration, operational control, ▇▇▇▇ review and audit functions for
      the Legacy Systems to [**], and (b) [**] the data center (including data
      center operations and billing operations) in respect of the Systems using
      "ENSEMBLE" technology (including system administration and operational
      control) to [**], in each case provided that: (i) there is no disruption,
      delay or degradation to the Services provided by Certen except to the
      extent that Certen has given reasonable notice to Bell in advance of any
      disruption and has taken all necessary or desirable steps to minimize
      disruption to the Services, (ii) Service Levels are maintained, (iii)
      disaster recovery services are fully available throughout the Term,
      including the period of the [**], (iv) there will be no impact on the
      compliance by Certen and the BCH Companies with the Personal Information
      Protection and Electronic Documents Act (Canada) or material violation of
      any other law or regulation by which any of the BCH Companies is bound,
      (v) there is no increased cost or expense, either direct or indirect, to
      Bell, including without limitation increased Transfer Taxes, unless Certen
      reimburses Bell for such amounts; and (vi) any such [**] does not cause
      any of the BCH Companies to be in breach of any corporate contract listed
      on Exhibit L-1 or of any other corporate contract of one or more of the
      BCH Companies, which Certen is managing for the BCH Companies or is
      providing services as a subcontractor. Bell agrees to Cooperate with
      Certen at Certen's expense in the performance of activities and
      implementation of procedures necessary to accomplish any such [**]. For
      the avoidance of doubt, if Certen so [**] any of such functions to [**],
      Certen shall continue to be obligated to invoice Bell for the Services in
      accordance with Section 12.1 of this Agreement.
5.15  CONTINUING ROLE OF [**] SYSTEMS. Subject to Certen's rights under Section
      5.14, it is agreed that after the Amendment Effective Date, [**]will
      continue to [**] in the Billing Operations Services and associated Ongoing
      Support Services performed in respect of the [**] Systems as they did
      immediately prior to such date and that it is in the best interests of
      Bell and Certen to have these parties continue to perform functions and
      deliver services after the Amendment Effective Date [**] that they did
      prior to such date, in connection with the Services provided under this
      Agreement. Prior to making any change to these arrangements, Certen shall,
      given the broader possible impacts of such decisions on Bell, review the
      proposed change with Bell. Certen shall not, except as contemplated in
      Sections 4, 5 and 21, make any proposed change unless Bell has provided
      its prior written consent in respect thereof, which prior written consent
      shall not be withheld if such a change would be in the best interests of
      both Bell and Certen, in accordance with the terms of this Agreement. The
      Parties agree to preserve the original spirit of this Agreement as it
      relates to [**] in the context of the Services in respect of the [**]
      Systems.
5.16  CONTINUING ARRANGEMENTS WITH [**] SYSTEMS. Subject to Certen's rights
      under Section 5.14, commitments made by Certen as of and since the
      Effective Date in respect
                                       27
      of [**] will continue to be honoured by Certen after the Amendment
      Effective Date in connection with the Billing Operations Services
      performed in respect of the Systems utilizing [**] technology. Prior to
      making any change to these arrangements, Certen shall, given the broader
      possible impacts of such decisions on Bell, review and coordinate the
      proposed change with Bell.
5.17  VIRUSES. Certen shall use all reasonable efforts to avoid viruses in
      accordance with Exhibit K.
5.18  ROLES AND RESPONSIBILITIES. Each of the Parties shall perform the roles
      and responsibilities assigned to it in Exhibits O-1 and O-2.
5.19  REMITTANCE AGREEMENTS. Bell is a party to the Remittance Agreements which
      the Parties acknowledge are Bell Corporate Contracts. However, the
      provisions set forth in this Agreement relating to corporate contracts
      shall be superseded by the following with respect to the Remittance
      Agreements:
      a.    With the prior written consent of Certen not to be unreasonably
            withheld, Bell shall have the right, at its option (exercised
            reasonably based on its conclusions with respect to (i) tax
            implications, (ii) impact on Bell or other Bell entities based on
            the scope of any Remittance Agreement being greater than the scope
            of the Services) to either (i) assign the Remittance Agreements or
            any one of them to Certen (an "ASSIGNMENT"), or (ii) provide Certen
            with the benefits of the Remittance Agreements or any one of them
            and appoint Certen as its agent (the "AGENCY APPOINTMENT"), in each
            case for the sole purpose of dealing with all matters arising under
            such Remittance Agreements to the extent they are part of the
            In-Scope Operations other than the payment of fees and commissions
            thereunder (for which Bell shall be responsible as set forth
            herein). As of the Effective Date, Bell has agreed to appoint Certen
            as its agent under all Remittance Agreements.
      b.    In the case of an Assignment, Certen will assume and perform all
            obligations of Bell under the relevant Remittance Agreements to the
            extent they are part of the In-Scope Operations (other than
            obligations relating to the payment of fees and commissions) and
            will indemnify and save the BCH Companies harmless from any Losses
            suffered by them arising from Certen's failure to perform such
            obligations.
      c.    In the case of an Agency Appointment, Certen shall act as agent for
            Bell with respect to all actions required to be taken by Bell under
            the Remittance Agreements to the extent they are part of the
            In-Scope Operations (other than with respect to the payment of fees
            and commissions) and Certen shall indemnify and save the BCH
            Companies harmless of and from any Losses suffered by the BCH
            Companies arising from a failure by Certen to perform such
            obligations of Bell under the Remittance Agreements to the extent
            such Losses (excluding Losses of any volume discounts benefiting
            Bell, if applicable) are caused by Certen and do not arise from an
            event, act or omission occurring prior to the Effective Date.
                                       28
      d.    Certen agrees that it will not amend, modify or waive any rights or
            obligations in the Remittance Agreements, whether in its capacity as
            primary obligor or agent, without ▇▇▇▇'▇ prior written consent if
            such amendment, modification or waiver could result in an increase
            in fees or commissions thereunder or would otherwise affect Bell. In
            no case shall any Remittance Agreement be extended, terminated or
            replaced without the prior written consent of Bell. In addition, in
            the case of an Agency Appointment, Bell shall have the option to
            negotiate, renew, replace or extend the Remittance Agreements
            directly or to delegate that power to Certen, in the latter case
            negotiation by Certen to be performed at its own cost. Certen shall
            also provide at no cost to Bell such assistance as Bell may
            reasonably request in connection with any such negotiations, renewal
            or extension. To the extent any modification in any Remittance
            Agreement or new Remittance Agreement expands Certen's
            responsibilities under the In-Scope Operations, such expansion shall
            be subject to the Change Order Process.
      e.    In the case of an Agency Appointment, Bell shall pay the amount of
            the invoice directly to the third party service provider under the
            applicable Remittance Agreement (the "THIRD PARTY").
      f.    In the case of an Assignment, the Parties shall make all reasonable
            efforts to arrange for invoices to be sent by the Third Party
            directly to Bell and for Bell to continue paying the amount of the
            invoice directly to the Third Party. In the event that the Parties
            mutually agree that it is not feasible for invoices to be sent
            directly from the Third Party to Bell, Certen shall forward each
            invoice received from the Third Party to Bell within a reasonable
            time of receipt thereof and Bell shall pay the amount of the invoice
            to Certen, which shall in turn, pay the Third Party.
      ▇.    ▇▇▇▇ will indemnify Certen for any Losses incurred by it as a result
            of the failure of ▇▇▇▇ to pay such fees and commissions; provided,
            that where, in accordance with subsection e or f above, Certen is
            required but has failed to forward the invoice to Bell within the
            agreed time or pay such invoices where it has received the invoice
            amount from Bell and has agreed to remit same to the Third Party,
            Certen shall indemnify the BCH Companies for any Losses incurred by
            the BCH Companies arising from such failure.
      h.    For greater certainty, the Parties acknowledge and agree that Bell
            and the BCH Companies shall have no obligations or liabilities in
            respect of fees and commissions attributable to third party
            customers of Certen. Before a Third Party charges Certen fees and
            commissions attributable to third party customers, Certen shall
            require such Third Party to invoice Certen separately so that the
            invoices provided to Bell include only those fees and commissions
            properly attributable to Bell and the BCH Companies.
      i.    If Certen comes into possession or control of any cheques or other
            negotiable instruments payable to Bell or any of ▇▇▇▇'▇ Affiliates,
            whether in connection with any Remittance Agreement or otherwise,
            Certen shall hold in trust for Bell the funds represented thereby
            and forward such funds as Bell may from time to time
                                       29
            direct. When processing any cheques or other negotiable instruments
            for Bell, Certen shall use its best efforts to ensure that such
            cheques are not lost, stolen or destroyed by any means whatsoever
            and Certen shall not withhold or delay the processing of any cheque
            or negotiable instrument payable to Bell that comes into its
            possession or control whether in connection with any dispute or
            otherwise. Bell shall have the right to require at any time that all
            cheques or other negotiable instruments payable to Bell or any of
            ▇▇▇▇'▇ Affiliates be sent or delivered by third parties directly to
            ▇▇▇▇.
SECTION 6. [**] AND [**]
6.1   CERTEN AS [**] SUPPLIER. Bell agrees that throughout the Term of this
      Agreement Certen shall be its [**] supplier:
      a.    with respect to Bell [**] Bell [**], of all Customer Care Operations
            Services and associated Ongoing Support Services and of all Billing

            case within the scope of Exhibit A, for all Lines of Business; and
      b.    with respect to Bell [**] other than Bell [**], of all Billing
            Operations Services and associated Ongoing Support Services within
            the scope of Exhibit A, for all Lines of Business.
      c.    Without derogating from any other rights of Certen, the Billing

            but not limited to the following:
            (i)   Bell will support Certen's efforts to market and sell services
                  to such companies on reasonable notice by giving endorsements
                  of such services, provided that such endorsements can be given
                  in good faith, and hosting a reasonable number of site visits
                  and demonstrations of such services at ▇▇▇▇'▇ sites.
            (ii)  Bell will introduce Certen to appropriate management and

                  meetings as agreed.
            (iii) Within [**] of the end of each calendar year, a responsible
                  financial officer of Bell will certify to Certen in writing
                  that the bills prepared by Certen under this Agreement
                  comprise a [**] of the BCH Companies and their subsidiaries
                  within such calendar year. Such certification will include
                  sufficient detail for Certen to verify the accuracy of the
                  certification. If requested by Certen, ▇▇▇▇'▇ independent
                  auditor will also certify the correctness of such information,
                  at Certen's expense. At Certen's option, if in any calendar
                  year, the bills prepared by Certen under
                                       30
                  this Agreement do not comprise the [**] of the BCH Companies
                  and their subsidiaries, then in the following calendar year,
                  the [**] Right under the Master License and Services Agreement

                  terms are defined under the Master License and Services
                  Agreement); provided that if Certen exercises this option,
                  this shall be Certen's [**] for ▇▇▇▇'▇ breach of Section 6.1c.
6.2   NEW SERVICES. The Parties further agree that in the event of New Services
      (which for greater certainty shall not include the Services to which
      Section 6.1a or 6.1b applies, or the services to which the Master License
      and Services Agreement applies), [**] shall be provided with the [**] to
      respond to and [**] on any request for [**] (both formal and informal
      requests) issued by any of the BCH Companies for such New Services. The
      BCH Companies will [**] to Certen [**] of [**] and provide Certen with the
      opportunity to [**], unless, in the BCH Companies' good faith discretion,
      such [**] to submit a [**] or [**] of the BCH Companies' [**]. Subject to
      the foregoing, the BCH Companies shall have the good faith discretion to
      determine which [**], among all of the [**], is the [**] to the BCH
      Companies. In addition, the Parties acknowledge and agree that certain New
      Services may have to be rendered by third party service suppliers that

      Companies for the performance of certain services, to the exclusion of
      Certen. However, throughout the Term, the BCH Companies shall [**], which
      are inconsistent with the rights granted to Certen under this Section. Any
      New Services which Bell requests Certen to provide shall, at ▇▇▇▇'▇
      option, (a) be included in this Agreement pursuant to terms and conditions
      to be negotiated pursuant to the Change Order Process, in which case such
      New Services shall be deemed to be Services for the purposes of this
      Agreement except with respect to the application of Section 6.1 of this
      Agreement, or (b) be provided pursuant to other agreements, the terms and
      conditions of which shall be negotiated by the Parties.
6.3   PROMOTION OF SERVICES. In the event that any of ▇▇▇▇'▇ Affiliates wish to
      obtain the services of Certen, such Affiliates and Certen will negotiate

      conditions shall be similar to the terms and conditions applicable to the
      Parties hereunder.
SECTION 7. SERVICE LEVELS GUARANTEES
7.1   SERVICE LEVELS. Subject to Sections 5.5 and 5.6, Certen will provide the
      Services in accordance with or in excess of the Service Levels set forth
      in Exhibit C-1 and Exhibit C-2.
7.2   SERVICE LEVEL IMPROVEMENTS. Where feasible and as part of Certen's general
      business strategy with respect to all of its customers, Certen will
      develop an ongoing quality improvement process in its provision of

7.3   CRITICAL SERVICE LEVEL KVMS. Certen will report on its compliance with the
      Critical Service Level KVMs on a [**] basis, in accordance with Exhibit

            times will be a resident of Canada for the purposes of the Income

                                       35
            non-Canadian resident entity. As between Certen and ▇▇▇▇ and except

10.8  EXPIRATION OF UNIT PLAN. After the expiration of the initial [**] years of
      the Term and for each year thereafter during the Term, Certen will report

      accordance with the Base Fees (as set forth in Exhibit B) and this Section
      10.

      [**] that Certen offers any other customer in the Territory for comparable
      services to those provided under this Agreement and for comparable
      volumes. In the event that during the Term of this Agreement, Certen
      actually offers [**] to any other customer in the Territory for services
      of the comparable type and volume as those provided under this Agreement,
      Certen shall make [**] available to the BCH Companies, and this Agreement

      is [**] percent ([**]%) or [**] than the revenue contemplated in the [**]
      on an annual basis for any given [**] (the "[**] REVENUES"), the Parties
      agree to the following: If the [**] exceeds the [**] identified in the
      [**] from such Services with respect to the applicable [**] by [**]
      percent ([**]%) (the "[**] PORTION"), ▇▇▇▇ shall be entitled to [**]

      Companies, Certen shall provide, [**] from each calendar quarter, the
      required assistance needed to determine the amount of the Fees
                                       37
      under Section 10 that have been paid for qualifying SR&ED conducted by
      Certen or contracted by Certen to another party (including Amdocs or any
      of its Affiliates) for each calendar quarter.
      Certen shall provide (i) such documentation and other information as may
      reasonably be required to assist the BCH Companies in claiming such tax

      authorities with regard to such tax incentives.
SECTION 12. INVOICING AND PAYMENT
12.1  INVOICES. Certen shall invoice ▇▇▇▇ at the beginning of the month in which
      the Services, which are the subject of the invoice, are to be provided.

      month(s) (versus the estimate made by Certen in the previous month's
      invoice) and the appropriate adjustments for Penalty Rebates, bonuses or
      credits in accordance with Section 7, Section 10 and Exhibit B. Each
      charge submitted on an invoice pursuant to this Agreement shall be paid by
      ▇▇▇▇ (and broken down for each of the BCH Companies) within [**] of
      receipt. Any amount submitted on any such invoice disputed in good faith
      by ▇▇▇▇ shall be paid according to the true-up procedure described above,
      and, in any case, not later than [**] after the dispute is resolved or
      arbitrated in accordance with Section 18.
12.2  FORM. Each invoice submitted pursuant to this Agreement shall be in such
      form as ▇▇▇▇ and Certen shall agree and shall be accompanied by such
      supporting information as shall be reasonably requested by ▇▇▇▇.
12.3  PROCEDURES. The following further procedures shall apply to invoices
      issued hereunder:
      a.    any payment to Certen from ▇▇▇▇ shall be transmitted by ▇▇▇▇ to a
            designated bank account of Certen by electronic funds transfer, and
            at ▇▇▇▇'▇ specific request, through Internet based technology; and
      b.    any payment not so forwarded shall be subject to a late payment
            charge. The late payment charge shall be charged against the portion
            of the amount not so received or deemed to be received multiplied by

            per annum, calculated daily, or as otherwise mandated by regulatory
            or governmental authorities; but in no event shall the applicable
            Late Factor exceed the maximum rate permitted under applicable usury
            laws. Any late payment charge shall be separately itemized by Certen
            in its next invoice and shall be payable by ▇▇▇▇ to Certen by the
            due date for that invoice.
12.4  TRANSFER TAXES.
      a.    The recipient (whether ▇▇▇▇ or an Affiliate or Certen, as the case
            may be, in this section referred to as "RECIPIENT") of any of the
            transactions contemplated in this Agreement shall be liable and
            responsible for any all applicable Transfer Taxes
                                       38
            with respect thereto. All such applicable Transfer Taxes shall be
            invoiced by the supplier (whether ▇▇▇▇ or an Affiliate or Certen, as
            the case may be, in this section referred to as "SUPPLIER") to
            Recipient. Recipient agrees to pay all such applicable Transfer
            Taxes upon receipt of an invoice or equivalent documentation from
            Supplier. The Supplier agrees to provide to the Recipient an invoice
            or equivalent documentation in which the Supplier will separately
            state the amount of any Transfer Taxes collectable by the Supplier.
            Recipient shall pay such applicable Transfer Taxes to Supplier,
            unless the relevant laws permit Recipient to self-assess and/or
            remit the Transfer Taxes directly to the Transfer Tax authority.
            Notwithstanding the foregoing, if the relevant laws authorize
            Recipient to provide to Supplier a purchase exemption certificate or
            otherwise qualify for exemption from the payment of any Transfer
            Tax, the Recipient may provide to Supplier a valid purchase
            exemption certificate or other similar certificate, permit,
            documentation or information which supports exemption from Transfer
            Tax and Supplier will not collect Transfer Taxes in connection with
            the transactions to which the purchase exemption certificate relates
            in accordance with and subject to the limitations and/or exceptions
            in the relevant laws.
      b.    Notwithstanding anything in this Section 12.4, where Supplier,
            acting reasonably, makes a determination that a particular
            transaction is subject to Transfer Taxes and Recipient disagrees,
            Supplier shall charge Transfer Taxes and Recipient shall pay such
            Transfer Taxes upon receipt of an invoice or equivalent
            documentation from Supplier. The Supplier shall, within a reasonable
            time after an inquiry by the Recipient, made in good faith, provide
            the Recipient an explanation concerning any determination of
            Transfer Tax treatment made by the Supplier pursuant to this
            paragraph.
      c.    In the event Recipient pays any Transfer Taxes and a determination
            is subsequently made by the relevant Transfer Tax authority that
            such Transfer Taxes were (1) not applicable or (2) subject to
            repayment, reduction, exemption, refund, or rebate, Recipient may
            submit a written request to Supplier for a repayment, adjustment, or
            credit. To the extent that any such payment, adjustment or credit
            may be made by Supplier directly to Recipient pursuant to the
            relevant laws, Supplier shall make a payment to Recipient or provide
            an adjustment or credit to Recipient in the manner and as required
            by the applicable laws. In the event that the relevant laws do not
            permit Supplier to make payment to Recipient or provide an
            adjustment or credit to Recipient of the Transfer Taxes, Supplier
            shall cooperate with Recipient to enable Recipient to claim a
            credit, reduction, exemption, refund or rebate of the Transfer Taxes
            under the relevant laws.
      d.    Supplier and Recipient agree to fully cooperate and to provide
            information to each other to: (a) enable Supplier and Recipient to
            more accurately determine their respective Transfer Tax liability in
            respect of the amounts that are payable by the Recipient to the
            Supplier, and to minimize such liability to the extent legally
            permissible; (b) without restricting the generality of paragraph
            (a), Supplier shall: (1) provide to Recipient confirmation of the
            Supplier's valid Sales and Related
                                       39
            Taxes registration numbers when requested by the Recipient, and (2)
            provide to Recipient copies of any interpretations or rulings, if
            any, obtained from any Transfer Tax authority to substantiate the
            Transfer Tax treatment in respect of the amounts payable by
            Recipient to Supplier, and (3) use best efforts to provide any other
            information or document which reasonably may be requested by
            Recipient in respect of the amounts payable by Recipient to
            Supplier, including but not limited to the information or documents
            specified in the Input Tax Credit (GST/HST) Information Regulations;
      e.    Supplier and Recipient also agree that in the event any fees or
            other amounts payable hereunder become subject to Transfer Taxes or
            are asserted or expected to be asserted to be taxable by any
            Transfer Tax authority, Supplier and Recipient will take
            commercially reasonable steps, if warranted, to restructure the
            provision of those services or other items in a manner acceptable to
            Recipient and Supplier which would cause those services or other
            items to be exempt from Transfer Taxes. Recipient shall reimburse
            and hold Supplier harmless for reasonable legal fees incurred by
            Supplier to restructure the provision of such services or other
            items. If the Supplier incurs other operational costs to restructure
            the provision of such services or other items, the Recipient shall
            negotiate with the Supplier in good faith to reimburse the Supplier
            a reasonable amount of such other costs.
      f.    Supplier further agrees to notify Recipient promptly but no more
            than [**] following the receipt of notification of an audit by a
            Transfer Tax authority in respect of any amounts payable by the
            Recipient to the Supplier in the time period after Closing.

            hereunder to any Software which is licensed by Certen or Amdocs to

            respect of such Intellectual Property Rights, which licence shall be
            equivalent in scope to the licence granted by Certen or Amdocs to

            modified, added to or changed in order to Develop such Code and

SECTION 16. CONFIDENTIAL INFORMATION
16.1  Subject to this Section 16, each Party agrees to preserve in confidence
      and secrecy all Confidential Information of the other Party and will not
      use same for its own purposes except for the sole purpose of fulfilling
      its obligations under this Agreement and will not reveal the content or
      existence of such Confidential Information to Persons not authorized in
      writing by such other Party to receive the same and will take all
      reasonable security precautions necessary to prevent unauthorized Persons
      from obtaining such Confidential Information. The recipient of the
      Confidential Information agrees to use the same care and discretion to
      avoid disclosure, publication or dissemination of Confidential Information
      as it uses with its own similar information that it does not wish to
      disclose, publish or disseminate, and in any event, shall exercise a
      reasonable degree of care with respect to Confidential Information
      provided by the other Party. Notwithstanding the foregoing, a Party (the
      "DISCLOSING PARTY") may disclose such information to any of its approved
      agents or subcontractors involved in the performance of a Party's
      obligations
                                       44
      under this Agreement, with the prior written consent of the other Party,
      such consent not to be unreasonably withheld, if such disclosure is
      necessary to permit the approved agent or subcontractor to perform its
      duties hereunder, provided that: (i) any disclosure to such agents or
      subcontractors shall be under terms and conditions set forth in the
      respective non-disclosure agreements of the Parties, in accordance with
      Sections 16.15 and 16.16, as applicable, below; and (ii) the Disclosing
      Party shall take all necessary action to ensure compliance with such terms
      and conditions by any such agent or subcontractor; and (iii) the
      Disclosing Party shall assume responsibility for any unauthorized
      disclosure of Confidential Information by such agent or subcontractor.
      Notwithstanding the foregoing, a Party may disclose Confidential
      Information to those employees of its Affiliates who require such
      Confidential Information for the purposes of this Agreement.
      Notwithstanding any other revision of this Agreement, this Section 16
      shall survive termination of this Agreement and continue thereafter.
16.2  Neither Party shall make, nor permit to be made, whether by photocopy or
      otherwise, any copies, abstracts or summaries of any of the other Party's
      Confidential Information except in pursuance of its obligations under this
      Agreement.
16.3  The obligations in Sections 16.1 and 16.2 shall not apply to:
      a.    Confidential Information that has been published or has otherwise
            entered the public domain without a breach of this Agreement;
      b.    Confidential Information that is acquired on a non-confidential
            basis from third parties who did not have an obligation of
            confidentiality owing to the Party which owns the Confidential
            Information;
      c.    Confidential Information that was already in the receiving Party's
            possession or was known to the receiving Party before the date
            disclosed to them by the Disclosing Party; or
      d.    Confidential Information that is independently developed by the
            receiving Party without the use of the Confidential Information.
      The burden of proof in respect of any exception in Section 16.3 shall be
      upon the Party seeking to rely on the exception.
16.4  It is not a breach of this Agreement to:
      a.    disclose Confidential Information that is required to be disclosed
            by law, judicial or arbitration process or by governmental
            authorities so long as the Party proposing to so disclose provides
            the other Party with reasonable prior notice of such requirement in
            order to permit the other Party to interpose an objection or seek an
            appropriate order to prevent or limit disclosure; or
      b.    disclose Confidential Information that is disclosed with the prior
            written consent of the other Party.
                                       45
16.5  Each Party acknowledges and agrees that, in the event of breach of any
      provision of Section 16 of this Agreement by it or by its agents or
      subcontractors, the other Parties may be irreparably harmed and entitled
      to equitable relief, including injunction, in addition to any right at law
      to damages in respect of any harm arising from such breach.
16.6  Each Party acknowledges and agrees that no license is hereby granted
      directly or indirectly under any patent, trade secret, trademark or
      copyright now held by, or which may be obtained by or which is or may be
      licensable by the Disclosing Party with respect to Confidential
      Information. Unless expressly provided herein, this Agreement shall not be
      construed as granting or conferring any rights by license or otherwise,
      express or implied, for any invention, discovery or improvement made,
      conceived or acquired prior to or after the date of this Agreement.
16.7  This Agreement shall be considered Confidential Information for the
      purposes of this Section 16, except that the Agreement can be disclosed to
      each Party's bankers, directors, officers, accountants, lawyers, financial
      analysts and other advisors and consultants, subject to the
      confidentiality obligations under this Section 16. This Agreement may also
      be disclosed in confidence to a relevant regulatory agency pursuant to an
      order or directive to such effect, subject to Section 16.4a above.
16.8  All material subcontracts or material agency contracts together with any
      other contracts entered into between Certen and third parties material to
      the provision of the Services shall contain confidentiality provisions, as
      reasonably requested by the BCH Companies. For the purposes of this
      Section 16.8, whether a subcontract or agency contract is "material" shall
      be determined by Bell, with reference not to the monetary value of the
      relevant subcontract or contract but to the third party's access or
      potential access to Confidential Information of the BCH Companies and/or
      by the strategic value of such subcontract or contract to the provision of
      the Services.
16.9  Each Party agrees to promptly return to the Disclosing Party, upon its
      request, or certify as destroyed all Confidential Information of the
      Disclosing Party in whatever form, including all electronic and magnetic
      copies and notes thereof, regardless of whether such Confidential

            procedure, which may or may not require the submission of written
            arguments by the Parties or the holding of hearings. In any event,
            the Parties agree that any arbitration hearing shall take place in
            the Province of Ontario.
      c.    Both Certen and the BCH Companies shall [**] their respective

            Section 18.
      d.    The Parties to the arbitration shall be entitled to be represented
            at any arbitration hearing by legal counsel and to be accompanied by

            Parties hereto believes that it is entitled to any provisional
            measure or injunctive relief, such Party shall be entitled to seek
            such measure or injunctive relief through civil action before any
            court having jurisdiction.
      f.    The Arbitrator shall be entitled to appoint an expert, if necessary,
            subject to agreement of the Parties. Any costs or fees charged by
            experts shall form part of the costs of the arbitration and be paid
            in the manner hereinafter contemplated.
      g.    The Arbitrator shall endeavour to render his/her decision (the
            "ARBITRATION AWARD"), within thirty (30) days following the date of
            commencement of the deliberation, but shall not lose jurisdiction by
            reason of his/her failure to respect this delay. The Arbitration
            Award must be made in writing stating the [**] and a copy thereof
            must be delivered to each Party to the arbitration. The Arbitrator,
            in the Arbitration Award, shall apportion costs and expenses in the
            manner he sees fit, taking into consideration the intent of the
            Parties as set forth in paragraph h. below.
      h.    The intent of the Parties is to have the Party who is [**] and [**]
            for the time and [**] arbitration to be required to [**] for the
            [**] thereof in order that each Party has significant [**] incentive
            to work together to resolve any differences that may arise between
            them.
      i.    The Arbitration Award shall be final and binding upon the Parties to
            the arbitration for all purposes and shall preclude, in respect of
            the subject matter in dispute, any further or other recourse to any
            Court otherwise having jurisdiction.

                                                                 increments.
            The Parties agree that the termination charge listed in the right
            hand column above is a genuine pre-estimate of damages and does not
            constitute a [**]. The termination charge is to be paid without
            deduction or set off on account of mitigation. Certen is under no
            obligation to mitigate damages represented by the termination
            charge. This provision shall not derogate from Certen's obligation
            to mitigate Costs, as set forth above in this Section.
            If ▇▇▇▇ [**] the Initial Term for the [**] period set out in Section
            3 above, the parties will [**] any termination for convenience
            charges applicable during such [**] period.
      b.    Notwithstanding Section 21.1a above, ▇▇▇▇'▇ right to terminate this
            Agreement for convenience shall not apply for the [**] period
            following the Amendment
                                       53
            Effective Date. For greater certainty, ▇▇▇▇ may provide notice of
            termination to Certen as specified in Section 21.1a during such
            [**], provided that such termination will not become effective prior
            to the end of such [**] period.
21.2  MATERIAL BREACH. Upon written notice, either Party may terminate this
      Agreement, without charge to the terminating Party, in the event of a
      material breach by the other Party. The Party seeking termination will
      provide the other Party with prior written notice of such material breach
      and a [**] opportunity to cure same. If the nature of any non-monetary
      breach is such that it would be unreasonable to expect a cure within the
      [**] period, the breaching Party shall be given an additional [**] to cure
      such breach. In the event that a material breach is not cured within the
      period specified above after delivery of the notice, the non-breaching
      Party, after fully complying with the [**] above (subject to Section 3.9.3
      of Exhibit C-1 and Section X of Exhibit C-2), may terminate this
      Agreement, which termination shall be effective, as of a date specified in
      such notice of termination, but in no event earlier than the expiration of
      the cure period required by this Section. In addition, ▇▇▇▇ retains the
      right to terminate this Agreement on grounds expressly set forth in
      Exhibit C-1 and Exhibit C-2. The terminating Party shall have all rights
      and remedies generally afforded by law or equity, subject to the
      limitations expressed in this Agreement.
21.3  TRANSITION-OUT. It is the intent of the Parties that at the expiration or
      termination, for any reason whatsoever, of this Agreement, Certen will
      Cooperate with the BCH Companies to assist with the orderly transfer of
      the Services, functions and operations provided by Certen hereunder to
      another services provider or the BCH Companies themselves, all as set
      forth in Exhibit J (Transition-Out Planning and Services).
21.4  INSOLVENCY. Without prejudice to any other rights at law or in equity or
      as otherwise contemplated in this Agreement, any Party shall have the
      right to terminate this Agreement, by written notice if the other (or, in
      the case of Certen, any company which directly or indirectly controls it)
      shall: (a) apply for or consent to the appointment of, or the taking or
      possession by a receiver, custodian, trustee or liquidator of it or all or
      a substantial portion of its property, whether pursuant to the laws of
      Canada or any province therein or of the United States of America or any
      state thereof or any other jurisdiction; (b) make a general assignment for
      the benefit of creditors or any assignment in violation of Section 27; or
      (c) commence a voluntary assignment or has an involuntary assignment or
      petition commenced against it under the Bankruptcy and Insolvency Act
      (Canada) or any similar legislation or statutory relief whether pursuant
      to the laws of Canada or any province therein or of the United States of
      America or any state thereof or any other jurisdiction. In any such event,
      the Party exercising the foregoing right to terminate shall promptly
      notify the other Parties in writing of its intent to terminate this
      Agreement, and such termination shall be effective upon the date specified
      in such notice.
21.5  CHANGE IN CONTROL OF CERTEN. Certen shall obtain the prior written consent
      of ▇▇▇▇ to any acquisition, directly or indirectly, by a [**] within the
      Territory of [**]% or more of the voting securities of Certen. If, without
      first obtaining the written consent of ▇▇▇▇: (i) a [**] in the Territory
      acquires, directly or indirectly [**]% or more of the voting securities of
      Certen, or (ii) Certen is merged or amalgamated with or into any Person
      that is a [**]
                                       54
      in the Territory to form a new Person, then, at any time after the first
      to occur of such events but not later than [**] after the last to occur of
      such events, ▇▇▇▇ shall have the right to terminate this Agreement,
      without charge to ▇▇▇▇ (including, for greater certainty, any payment
      under Section 21.1), by delivering to Certen written notice.
21.6  TERMINATION FOR A FORCE MAJEURE EVENT.
      a.    if:
            (i)   a Force Majeure Event has occurred resulting in a cessation of
                  the Services and continues for a period of 30 days or in the
                  case of a labour strike or other material labour disruption,
                  180 days, and ▇▇▇▇ has delivered to Certen a Declaration of

            (ii)  within three days after the delivery of the Declaration of
                  Cessation, Certen has been unable to recommence performance of
                  such Services itself or directly engage an alternate source
                  which has commenced performance of such Services,
            then ▇▇▇▇ may terminate this Agreement by delivering to Certen a
            termination notice on not less than 24 hours notice at any time
            prior to or on the effective date of termination specified in the
            notice.
21.7  OBLIGATION TO PAY FOR SERVICES RENDERED PRIOR TO TERMINATION. In the event
      of any termination of this Agreement in accordance with the terms hereof,
      ▇▇▇▇ shall pay Certen for Services rendered prior to the actual date of

22.1  If this Agreement is terminated or expires for any reason whatsoever then:
      a.    the Transition-Out Plan and related services as contemplated in
            Exhibit J of this Agreement, shall be implemented;
                                       55
      ▇.    ▇▇▇▇ shall be responsible for payment for the Services rendered

            and

22.4  In order to assist in a smooth and orderly transition-out in accordance
      with the Transition-Out Plan, Certen shall request from lessors, vendors,

            directly to this Agreement, and Certen employees relating to the
            performance of the Services by Certen, and the premises where same
            are located. Such access shall be for the sole purposes of

                  in respect of operational risks;
            (v)   the amount of any compensation payments and cost increases
                  pursuant to Section 4 of Exhibit B (Fees) (the audit
                  applicable to this item shall be performed by an independent
                  third party auditor);
            (vi)  compliance with the control and security measures relating to
                  the Systems, the BCH Companies Data, Intellectual Property and
                  the obligations of Certen and its sub-contractors hereunder
                  relating thereto, as specified in Exhibit K; and
            (vii) the completeness and accuracy of any/all changes to BCH
                  Companies billing data, related Systems, processes and/or
                  applications, including the process for, and management

            Section 23.3 [**] ▇▇▇▇; provided, however, that if Certen is
            requested to provide assistance to an extent which is not reasonable
            or standard, Certen shall so advise ▇▇▇▇ and ▇▇▇▇ shall have the
            option of reducing such assistance to a reasonable level which is
            mutually acceptable to the Parties or of paying Certen [**] such
            additional efforts. Except as provided in Section 23.3(b)(v), the
            BCH Companies shall have no right to audit any cost or pricing data,
            the composition of rates or fees invoiced, records and information
            pertaining to any other client or Certen's accounting policies or
            practices. Following the delivery to Certen of an audit or
            assessment report or security review produced in accordance with
            Section 22.1 above and this ▇▇▇▇▇▇▇ ▇▇.▇, ▇▇▇▇▇▇ will take timely
            corrective action in respect of any deficiencies, identified by the
            audit or assessment, [**] to the BCH Companies (subject to Section
            5.11 of this Agreement), to the extent such deficiencies relate to
            the delivery of the Services and were substantially caused by
            Certen. Such action shall be documented in a formal action plan and
            provide a sufficient level of detail, including as a minimum:
                  -     description of the deficiency or finding;
                  -     description of the action taken or proposed to be taken
                        to resolve the deficiency or finding;
                  -     an implementation schedule with specific completion
                        dates for each action item.
      All such action plans shall be submitted in writing by Certen to the BCH
      Companies within a reasonable period from the date of delivery to Certen
      of the audit or assessment report. Quarterly status reports shall be
      provided by Certen to the BCH Companies
                                       58
      regarding all outstanding deficiencies until such deficiencies are
      resolved to the satisfaction of BCH Companies, acting reasonably. In
      respect of critical deliveries, the Parties may agree to more frequent
      reporting based on severity.
      Certen shall assist the BCH Companies auditors in their endeavors to
      obtain assurance that audit or assessment findings have been
      satisfactorily addressed. In the event of disagreement between Certen and
      the BCH Companies regarding the need to address audit or assessment
      findings or the appropriate action necessary to resolve any such findings,
      such disagreement shall be resolved by arbitration in accordance with the
      dispute resolution provisions of Section 18 hereof.
23.4  SECURITY PROCEDURES. Certen shall follow and shall ensure that its
      employees, subcontractors, agents or other representatives follow the
      security procedures described in Exhibit "K", Security, Access and
      Interface (subject to contracts with subcontractors in effect prior to the
      Effective Date and which were transferred to Certen by the BCH Companies,
      or from which Certen benefits, in accordance with this Agreement), which
      references the BCH Companies' Security Standard for Computer and Access
      Control as may be amended, reasonably, from time to time by the mutual
      written consent of the parties; provided that any material additional
      costs resulting from such an amendment shall be dealt with in accordance
      Change Order Process, with any disagreement to be resolved by arbitration
      in accordance with the dispute resolution provisions of Section 18 hereof.
      Certen may request the BCH Companies' consent to vary from these standards
      as may be reasonably required, which consent shall not be unreasonably
      withheld. The BCH Companies will follow and shall ensure that their
      employees, subcontractors, agents or other representatives follow Certen's
      security policy whenever visiting Certen's operations.
23.5  PIPEDA. Each Party, its agents and subcontractors and all employees or
      other representatives of any of them shall comply with the Personal
      Information Protection and Electronic Documents Act (Canada). In the event
      of any change, modification or adoption of a new provision to the said Act
      from the present version in effect on the date of this Agreement, the BCH
      Companies shall request that Certen provide an estimate of the reasonable
      additional costs and expenses that would be incurred by Certen to do same
      and time required to implement same together with supporting documentation
      to justify the estimate. The BCH Companies shall then decide whether
      Certen shall effect same and if the BCH Companies does so decide Certen
      shall implement same and the BCH Companies shall reimburse Certen's
      reasonable and pre-approved expenses incurred in so doing.

                                       60
      RECOVERABLE BY AN INDEMNIFIED PARTY AGAINST THE INDEMNIFIER (EXCEPT WHERE
      CONSEQUENTIAL DAMAGES ARE EXPRESSLY RECOVERABLE AS PROVIDED IN SECTION
      25.4 BELOW).
25.4  THE ABOVE MENTIONED LIMITATIONS (IN SECTIONS 25.1, 25.2 AND 25.3) WILL NOT
      APPLY TO: (I) ANY FAILURE BY ▇▇▇▇ TO PAY ANY ACCRUED BUT UNPAID AMOUNTS

      INCLUDING, BUT NOT LIMITED TO, THE TERMINATION CHARGES DESCRIBED IN

      UNDER WHICH CERTEN BENEFITS (I.E., UNDER THE CORPORATE CONTRACTS LISTED IN
      EXHIBIT L1) IN ACCORDANCE WITH THIS AGREEMENT AND WITH RESPECT TO THE
      LEGACY SYSTEMS SHALL BE LIMITED TO CERTEN'S OBLIGATIONS TO PROPERLY MANAGE
      SUCH CONTRACTS AND SUCH PARTIES IN ACCORDANCE WITH THIS AGREEMENT. IN
      ADDITION, CERTEN'S INDEMNITY OBLIGATIONS HEREUNDER WITH RESPECT TO
      BREACHES ARISING UNDER SUCH CONTRACTS SHALL BE LIMITED TO THE EXTENT THAT
      CERTEN IS INDEMNIFIED AND HELD HARMLESS BY SUCH SUBCONTRACTORS FOR THE

SECTION 26. FORCE MAJEURE
26.1  FORCE MAJEURE.
      a.    Neither Party shall be liable or deemed to be in default for any
            delay or failure in performance under this Agreement or the Exhibits
            hereto to the extent such delay or failure is directly caused by
            fire, flood, explosion, war, embargo, government requirement, civil
            or military authority, act of God, labour disruption, regulatory or
            legislative intervention or other similar causes beyond its control
            and anticipation or foreseeability and without any fault or
            negligence of the delayed or non-performing Party and provided that
            the delay or failure to perform could not have been prevented by
            reasonable precautions and cannot be reasonably circumvented by the
            non-performing Party through the use of alternate sources, work
            around plans or other means (including by meeting the obligations
            for performing disaster recovery services as described in Section
            5.10 of this Agreement) (each, a "FORCE MAJEURE EVENT").
                                       61
      b.    If a Force Majeure Event occurs, the non-performing Party shall be
            excused from further performance or observance of the obligations so
            affected for as long as the Force Majeure Event prevails and such
            Party continues to use all commercially reasonable efforts to
            recommence performance or observance without delay. Any Party so
            delayed in its performance shall immediately notify the Party to
            whom performance is due by telephone (to be confirmed in writing
            within 24 hours of the inception of such delay) and describe at a
            reasonable level of detail the circumstances causing such delay.
      c.    The Parties acknowledge and agree that the provision of the Services
            to ▇▇▇▇ under this Agreement is critical to the overall operations
            and financial performance of ▇▇▇▇ and that a substantial
            interruption of the performance of the Services would materially and
            adversely affect ▇▇▇▇. Accordingly, if a Force Majeure Event or a
            Guarantee Event results in the cessation of the Services (other than
            due to the fault of ▇▇▇▇ or a third party), then ▇▇▇▇ shall notify
            Certen in writing stating a claim that a Force Majeure Event or a
            Guarantee Event has occurred (a "DECLARATION OF CESSATION"), and
            then the following shall apply:
            (i)   Certen shall immediately begin to use all commercially
                  reasonable efforts to engage an alternate provider (including
                  ▇▇▇▇) to perform such Services or recommence performance of
                  such Services itself. Certen shall continue such efforts until
                  the first of the following to occur:
                  (A)   Certen recommences performance of such Services;
                  (B)   an alternate provider is engaged by Certen or ▇▇▇▇
                        pursuant to Section 26.1c(ii); or
                  (C)   this Agreement is terminated pursuant to Section 21.6.
            (ii)  If, after ten (10) days following the Declaration of
                  Cessation, Certen has not recommenced performance of such
                  Services itself or engaged an alternate provider (including
                  ▇▇▇▇), Certen will, for a five (5) day period allow ▇▇▇▇
                  access to Certen's facilities as necessary for ▇▇▇▇ to assist
                  Certen in removing the Force Majeure Event or the Guarantee
                  Event, as applicable. Following such five (5) day period (the
                  "5-Day Period"), if the Services have not recommenced, ▇▇▇▇
                  may undertake to identify an alternate provider from which
                  Certen may be able to procure such Services. If ▇▇▇▇
                  identifies such an alternate source, ▇▇▇▇ shall first afford
                  Certen a reasonable opportunity to engage such provider to
                  perform such Services and manage such provider's performance,
                  but if that is not accomplished, and the performance of the
                  Services has not recommenced, then ▇▇▇▇ may itself engage such
                  provider to perform such Services (with Certen liable for
                  payment for such Services from such provider for so long as
                  the delay in performance shall continue, provided ▇▇▇▇
                  continues to pay Certen under Section 26.1(c)(iii)),
                  alternatively, ▇▇▇▇ may itself perform the Services. In such
                  circumstances that a third party provider is engaged, ▇▇▇▇
                  will first
                                       62
                  afford Certen a reasonable opportunity to manage such provider
                  performance, but if that is not accomplished, then ▇▇▇▇ may
                  itself manage such provider performance. Certen shall
                  reasonably cooperate with such provider and/or ▇▇▇▇, as the
                  case may be, including by providing access to such Systems,
                  Certen personnel, and information as are reasonably necessary
                  for such provider to perform the Services. Notwithstanding the
                  foregoing, if ▇▇▇▇ or a third party provider have been unable
                  to recommence the Services within seven (7) days of the end of
                  the 5-Day Period, then Certen, Bell and/or the alternative
                  provider, as the case may be, shall promptly cooperate as
                  necessary to transfer the performance of the Services back to
                  Certen.
            (iii) Subject to Section 21.6, Bell shall continue to pay amounts
                  due and payable by Bell to Certen hereunder upon the
                  occurrence of any Force Majeure Event or the Guarantee Event,
                  as applicable, but Certen shall not have the right to any
                  additional payments from Bell for costs or expenses incurred
                  by Certen as a result thereof.
            (iv)  Upon discontinuance of the Force Majeure Event or the
                  Guarantee Event, as applicable, unless the Agreement has been
                  terminated by Bell pursuant to Section 21.6, Certen, Bell
                  and/or the alternative provider, as the case may be, shall
                  promptly cooperate as necessary to transfer the performance of
                  the Services back to Certen.
26.2  DISASTER RECOVERY SERVICES; REFERENCE TO EXHIBIT I. This Section does not
      limit or otherwise affect Certen's obligations to provide disaster
      recovery services in accordance with Exhibit I; provided, however, that
      any Force Majeure Event does not also prevent Certen's provision of the
      Services from the recovery centers.
SECTION 27. ASSIGNMENT/SUBCONTRACTING
27.1  ASSIGNMENT. Except as provided in Section 27.2 below, neither Party shall
      assign any or all of its obligations herein, including the provision of
      the Services, to any third party unless with the prior written consent of
      the other Party, which consent may be unreasonably withheld. Any approved
      assignee shall expressly acknowledge and accept the provisions of this
      Agreement and the Exhibits hereto and agree that it is bound thereby as if
      it had been an original party and signatory to this Agreement.
      a.    Certen, upon written notice to Bell, may assign monies due and to
            become due to Certen under this Agreement provided that Bell shall
            be entitled to assert against the assignee thereof all rights,
            claims and defenses of every type which Bell could assert against
            Certen, whether acquired prior or subsequent to such assignment.
      ▇.    ▇▇▇▇ may assign this Agreement and any of its rights and obligations
            under this Agreement to any Affiliate of Bell or of BCE Inc.,
            provided that the assignee (i) is not a material competitor of
            Certen or Amdocs (it being agreed that each of [**] and [**] are
            competitors of Certen and/or Amdocs; however, the Parties will
                                       63
            review and update, from time to time, the applicability of this
            section to [**] and [**], subject to Certen's prior written
            consent); (ii) is a successor to the same or substantially the same
            service business (requiring the rendering of bills) that the BCH
            Companies have as of the Effective Date; and (iii) executes such
            documents as Certen may reasonably require to evidence the
            assumption by the assignee of such obligations under this Agreement.
            In any such event no such assignment shall relieve the BCH Companies
            from any liability or obligation arising hereunder. If any
            assignment permitted under this Section causes any increase in
            withholding tax liability, then such sums payable to Certen shall be
            increased by an amount such that following all required deductions,
            Certen receives the amount equal to the sum it would have received
            had no such deductions been made.
      c.    Certen may (A) assign this Agreement and any of its rights and
            obligations under this Agreement to any Affiliate of Certen which is
            a resident of Canada for the purposes of the Income Tax Act (Canada)
            or (B) amalgamate with any Affiliate of Certen which is a resident
            of Canada for the purposes of the Income Tax Act (Canada), provided
            that the assignee or amalgamating corporation (i) is not a material
            competitor of the BCH Companies; and (ii) executes such documents as
            the BCH Companies may reasonably require to evidence the assumption
            or confirmation by the assignee or amalgamating corporation of such
            obligations under this Agreement. In any such event no such
            assignment shall relieve Certen from any liability or obligation
            arising hereunder.
27.2  SUBCONTRACTING.
      a.    Certen shall not subcontract or otherwise delegate the delivery of
            any material part of the Services contemplated by this Agreement to
            any Person without: (a) the prior written consent of the BCH
            Companies, which consent may be unreasonably withheld; and (b) the
            execution by such Person of documentation satisfactory to the BCH
            Companies which protects the rights of the BCH Companies under this
            Agreement; except that Certen may (without the BCH Companies'
            consent) subcontract to Amdocs and any of its Affiliates for the
            performance of any Services or other obligations of Certen under
            this Agreement.
      b.    The approval by the BCH Companies of any subcontractor or other
            delegate, shall not relieve Certen of its obligations under this
            Agreement as primary obligor, subject to Section 24 above. In
            addition to its other obligations under this Agreement, Certen shall
            be responsible for the direct supervision, management and control of
            any approved subcontractors and other delegates and shall ensure
            that all such approved subcontractors and other delegates comply
            with the terms of and perform the Services in accordance with this
            Agreement. Notwithstanding any such contracting or delegating,
            Certen shall remain solely liable to the BCH Companies for the
            provision of the Services.
                                       64

      applicable federal, provincial, local and foreign laws, ordinances,
      regulations and codes, including identification and procurement of
      required permits, certificates, licenses, insurance, approvals and
      inspections in performance under this Agreement. Certen agrees to
      indemnify the BCH Companies, and Bell agrees to indemnify Certen, for any
      loss or damage that may be sustained by reason of any failure to do so. In
      connection with the performance of this Agreement, Bell shall, at Certen's
      request or expense, take steps reasonably required to facilitate Certen's
      compliance with this Section and Certen shall, at ▇▇▇▇'▇ request and
      expense, take steps reasonably required to facilitate ▇▇▇▇'▇ compliance
      with this Section.
28.2  Without limiting the foregoing obligations, any obligations under this
      Agreement shall be performed in compliance with all applicable legislation
      and government agency orders and regulations prohibiting discrimination
      against any employee or applicant for employment because of race, color,
      religion, sex, national origin, age or handicap. Where required by law,
      certificates of compliance shall be provided.
SECTION 29. PUBLICITY AND IDENTIFICATION
29.1  Certen shall not, except with the BCH Companies' written consent, engage
      in promotion or publicity about either Party's participation in this
      Agreement, the content(s) hereof or the relationships contemplated herein,
      or, in any circumstance connected herewith, make public use of any
      Identification of the BCH Companies, or any customer or supplier of any of
      them. As used herein, "IDENTIFICATION", means any copy or semblance of any
      trade name, trademark, service ▇▇▇▇, insignia, symbol, logo, designation

30.1  This Agreement shall not be amended except by written instrument signed by
      the Parties hereto.
SECTION 31. WAIVER
31.1  No indulgence or forbearance by either Party hereunder shall be deemed to
      constitute a waiver of its right to insist on performance in full and in a
      timely manner of all terms, covenants or conditions of the other Party
      hereunder and any such waiver, in order to be binding upon a Party, must
      be express and in writing and signed by such Party and then
                                       65
      such waiver shall be effective only in the specific instance and for the
      purpose for which it was given.
SECTION 32. SEVERABILITY
32.1  If any of the provisions of this Agreement shall be invalid or
      unenforceable, such invalidity or unenforceability shall not invalidate or
      render unenforceable this entire Agreement, but rather such provision
      shall be modified or severed (as the case may be) so as to maintain to the
      maximum extent possible the benefits of the Parties hereunder and the
      remaining provisions of this Agreement shall be unaffected thereby.
SECTION 33. SURVIVAL OF OBLIGATIONS
33.1  The obligations of the Parties under this Agreement that are stated to or

            B.    to describe the Services;
            C.    to define all existing applications that will be the baseline
                  definition of the Services for Certen's operation; and
            D.    to define all functions and responsibilities which are to be
                  performed by Certen in delivering the Services.
      1.1.2 This Exhibit A specifies the Services affecting the Legacy Systems,
            and Modernized Systems, which Services are the same or substantially
            the same as the customer care and billing services and operations
            provided internally or received by the BCH Companies (including ▇▇▇▇
            Sympatico and Bell Nexxia) just prior to the Effective Date.
            Notwithstanding the foregoing, only the customer care services which
            Certen agreed to provide to Bell (not including ▇▇▇▇ Sympatico and
            Bell Nexxia) as of the Effective Date form part of the Services
            hereunder. After the Amendment Effective Date, the Parties shall

            the Modernization. The Parties shall complete such review and
            modification by December 31, 2003. After completion of
            Modernization, the Parties shall further review this Exhibit A and
            adjust the description of the Services only to the extent it has
            changed as a result of further Modernization. The Parties
            acknowledge that Exhibits O-1 and O-2 represent the most current

            The Services defined below are the Services for which Certen has

            3.2.2 For greater certainty, the Parties recognize and agree that,
                  for purposes of the scope of Certen's [**] set forth in
                  Section 6.1 of the Agreement, the demarcation matrix set forth
                  in Table A1 of Annex 1:
                  (a)   shall not be subject to reduction; and
                  (b)   shall apply to Certen's provision of the various
                        services enumerated therein, irrespective of the Systems
                        on which such services are delivered (or any
                        modernizations or upgrades of such Systems), including
                        but not limited to, the Legacy Systems, the Modernized
                        Systems, and any other billing and/or customer care
                        Systems, whether acquired, licensed, leased, or
                        otherwise used by the BCH Companies throughout the Term,
                        and irrespective of the Lines of Business which are the
                        subject of such services.
            3.2.3 At anytime after the Effective Date, should any service
                  performed by or benefiting the BCH Companies fall within the
                  scope of Section 3.2.1 or 3.2.2, e.g., whether because such
                  service was not previously identified or is required as a
                  result of the acquisition by or use of the BCH Companies of
                  any System or application, such services shall be [**] to be
                  in [**] (subject to Certen's [**] under Section 6.1 of the
                  Agreement), and the BCH Companies shall transfer such
                  services, applications or systems to Certen, including any
                  relevant employees, in accordance with the Change Order
                  Process (as defined in Exhibit G) as applicable, unless the
                  Parties mutually agree in writing that, in the [**] of the BCH
                  Companies and Certen, such services, applications or systems
                  (including any related employees) shall not be transferred to
                  [**] and shall therefore be treated as [**] services for the

to and including the [**] Operational Year specified amounts (the "ENSEMBLE
CUSTOMIZATION CREDIT") as set forth in the table below, which are reserved to
[**] Projects which involve principally Ensemble Customizations (as defined
under the Master License and Services Agreement). This yearly [**], as detailed

(described in Exhibit D to this Agreement) both of which are excluded from the
following table, is included in the Business Case and is to be funded from [**]

Agreement and may be funded using either the [**] portions of the Ensemble
Customization Credit. Unspent amounts of the Ensemble Customization Credit may
be carried forward from one Operational Year to the next and may be spent in a
subsequent Operational Year. In addition, the [**] portions of the Ensemble
Customization Credit may be used to fund Projects involving principally Ensemble
Customizations performed by Third Party [**] (as described in the Master License
and Services Agreement) in which case Certen shall, upon receipt of evidence of
such expenditures, provide the BCH Companies with a credit which may be set-off
by the BCH Companies against any amounts owed by the BCH Companies to Certen. In
the event that the BCH Companies have not, by the end of the [**] Operational
Year, used the full amount of the Ensemble Customization Credit, any such unused
amount shall be paid by Certen to the BCH Companies within [**] after the end of
the [**] Operational Year. Notwithstanding Section 8.1 of this Exhibit, the time
and materials rate applicable to Development Work and related services which is
funded hereunder and under Section 10 of this Exhibit shall be performed: (i) by
Certen (excluding Amdocs and its Affiliates) at its [**](i.e., at a time and
materials rate of CA$[**] per hour); (ii) on behalf of Certen by Amdocs and its
Affiliates (other than Certen) on a [**] basis at the rates charged to Bell in
accordance with the Master License and Services Agreement; and (iii) on behalf
of Certen by its other (non-Affiliate) subcontractors at the rates [**].
The Parties acknowledge that, as of the Amendment Effective Date, there are no
outstanding amounts accrued under the Ensemble Customization Credit or the
Legacy Credit Pot .

         1.6      PENALTY REBATE/BONUS PAYMENT SCHEDULE
                  [NOTE : From the Amendment Effective Date, Bell has agreed to
                  [**] the Penalty Rebates/Bonuses calculation. Bell is
                  permitted during the Term, by giving Certen [**] written
                  notice to [**] the Penalty Rebates/Bonuses calculation
                  hereunder. Accordingly, the provisions in this Exhibit
                  relevant to Penalty Rebates/Bonuses calculations will only
                  apply [**] Bell.]
                  1.6.1   Actual payment or crediting of accumulated Performance
                          Penalty Rebates/Bonuses will be made at the time that
                          the BCH Companies' final payment in respect of an
                          Operational Year is due and payable under the
                          Agreement. Penalty Rebates/Bonuses are calculated [**]
                          by multiplying [**] by the [**] (as defined in Exhibit
                          B to this Agreement) for Services received by Certen,
                          associated with the applicable [**] generating the
                          Penalty Rebate/Bonus, during the [**] in which the
                          Performance Penalty Rebate/Bonus is incurred/earned.
                          Penalty Rebates/Bonuses shall not be applied under
                          both Exhibit C-2 and Exhibit C-1 for the same Miss.
                  1.6.2   If the aggregate of all Performance Penalty Rebates
                          due to the BCH Companies within a particular
                          Operational Year less the aggregate of all Bonuses due
                          to Certen from the BCH Companies in the same
                          Operational Year is positive, Certen will credit the
                          BCH Companies with the amount calculated, which credit
                          shall be applied to the Fees chargeable by Certen
                          commencing in the next Operational Year, and all
                          Performance Penalty Rebate/Bonus balances for the BCH
                          Companies will be reduced to zero for the next
                          Operational Year.
                  1.6.3   If the aggregate of all Performance Penalty Rebates

                          Operational Year less the aggregate of all Bonuses due
                          to Certen from the BCH Companies in the same
                                      -6-
                          Operational Year is negative, the Performance Penalty
                          Rebate balance will be reduced to zero, while the
                          amount calculated (i.e., the difference of Bonuses
                          minus Performance Penalty Rebates) will be carried
                          forward as an opening Bonus for the next Operational
                          Year.
                  1.6.4   With respect to the last Operational Year of the
                          Agreement (or any portion thereof if such Operational
                          Year is not a full twelve (12) calendar months), any
                          outstanding amount due to Certen (i.e., the difference
                          of aggregate Bonuses minus aggregate Performance
                          Penalty Rebates for that Operational Year or portion
                          thereof), will be paid by the BCH Companies up to (but
                          not exceeding) an amount equal to the aggregate sum of
                          all Performance Penalty Rebates credited to the BCH
                          Companies at the end of all previous Operational Years
                          of the Agreement.
2.       FRAMEWORK FOR SERVICE LEVELS AND PERFORMANCE CREDITS
         2.1      INTRODUCTION
                  This section sets forth the implementation and management of
                  the Service Levels.
         2.2      CRITICAL SERVICE LEVEL KVM IMPLEMENTATION
                  2.2.1   The agreed Critical Service Level KVMs shall be based
                          on the assumption that the information provided by
                          ▇▇▇▇ documenting the service levels reached by ▇▇▇▇
                          with respect to operations existing immediately prior
                          to the Effective Date (including but not limited to
                          the Performance Scorecard results, performance
                          history, and other measurements) is complete and
                          accurate.
                  2.2.2   In the event that either party has notice or knowledge
                          that any such information is or may be materially
                          incomplete or inaccurate, it shall promptly so notify
                          the other.
                  2.2.3   If the information referenced in Section 2.2.1 above
                          is not complete or accurate, the parties will promptly
                          update the Critical Service Level KVMs, including but
                          not limited to the Critical Service Level KVMs, the
                          Target KVMs, the Performance Thresholds, and the
                          Performance Scorecard results.
                                      -7-
         2.3      SERVICE LEVEL PLANNING
                  2.3.1   Service Levels are subject to review on the following
                          occasions throughout the Term:
                          -       Optional [**] Review : Within [**] of the
                                  Amendment Effective Date and every [**]
                                  thereafter, the parties will have the option
                                  to meet and review the Service Levels.
                          -       [**] Review : The parties shall set a
                                  mutually agreed date to conduct [**] reviews
                                  of the Service Levels and Certen's
                                  performance with respect to the Service
                                  Levels. At a minimum, the [**] review will
                                  include :
                                  -     Comprehensive review of the previous[**]
                                        performance;
                                  -     Revision of the Service Levels, if any,
                                        based upon mutual agreement; and
                                  -     review of the Critical Service Level KVM
                                        definitions, methods of measurement,
                                        targets and thresholds, credit/bonuses
                                        procedures, and any other relevant
                                        parameter, mechanism, or portion of
                                        this Exhibit C-1.
                                  No changes to any Service Levels shall
                                  become effective without the written
                                  approval of each Party's Operational Prime
                                  (as defined in Exhibit F). Upon the written
                                  mutual consent of the parties and in
                                  accordance with Exhibit G (Change Order
                                  Process), the parties shall adjust any part
                                  of the Critical Service Level KVMs and/or
                                  Performance Penalty Rebates/Bonuses. The
                                  parties acknowledge that they are or may
                                  become party to service level documents,
                                  defining the parameters of Service Levels,
                                  which documents are external to this
                                  Exhibit. Such documents may be altered by
                                  the mutual determination of the parties upon
                                  written agreement of each party's
                                  responsible Service Level Coordinator and
                                  Service Level Manager.
                  2.3.2   The BCH Companies recognize and agree that each BCH
                          Company's strategy for transition to Modernization
                          will likely include several planned rollouts, during
                          which both the Legacy Systems and the Modernized
                          Systems will be used in parallel. During such
                          period(s) of parallel use, the parties will agree on
                          ways to adjust (in accordance with this Section 2.3)
                          the Performance
                                      -8-
                          Penalty Rebate/Bonus computation model set forth
                          herein and in Exhibit C-2 to the changing environments
                          of the BCH Companies.
                  2.3.3   When considering such Critical Service Level KVM
                          adjustments, the parties will consider the impact of
                          improved and measurable performance capabilities due
                          to Systems that have been implemented by Certen
                          through the provision of Services and the
                          Modernization. In addition, the parties will consider
                          the impact of following circumstances:
                          A.   Development of a plan for improving Critical
                               Service Level KVMs based on mutually acceptable
                               changes to the Systems;
                          B.   New and different Services requested by the BCH
                               Companies;
                          C.   Addition or removal of Critical Service Level
                               KVMs, as appropriate, to reflect the ongoing
                               requirements of the BCH Companies;
                          D.   Additional performance levels for Services with
                               regard to which Certen will regularly measure and
                               report to the BCH Companies.
                  2.3.4   Modernization, if applicable, shall provide improved
                          Critical Service Level KVMs [**] to ▇▇▇▇.
         2.4      CRITICAL SERVICE LEVEL KVMS REPORTING
                  2.4.1   Unless otherwise agreed by the parties in writing,
                          Certen will produce and make available to ▇▇▇▇ [**]
                          the reports and/or measurement results in connection
                          with the Critical Service Level KVMs.
                  2.4.2   This includes usage of the same format and content
                          type used before the Effective Date for [**] reports
                          on Critical Service Level KVMs, which communicate
                          performance standards versus actual performance levels
                          achieved.
                  2.4.3   A sample of such reports and measurement methods and
                          the format and content types used with such reports
                          and measurements is attached to this Exhibit as Annex
                          1.

                          mutually by Certen and the applicable BCH Company
                          (collectively, the "PERFORMANCE SCORECARD"), to track
                          and evaluate [**] performance in the following areas:
                          BILLING & PAYMENT PROCESSING
                          - Accuracy
                          - Timeliness
                  2.5.2   For each Project, as part of the statement of work
                          relating thereto, the parties shall agree upon service
                          levels with regard to budget, timelines and delivery
                          (the "PROJECT SERVICE LEVELS KVMS"). During the term
                          of the Agreement, Certen shall provide each BCH
                          Company with [**] reports with respect to all Projects
                          carried out thereby for each BCH Company [**].
         2.6      PRE-EFFECTIVE DATE SERVICE LEVEL AGREEMENTS WITH [**]
                  Certen will meet the required service levels in all BCH
                  Company contracts with the [**], as listed in Exhibit M3 of
                  the MOSA provided that (i) Certen's performance with respect

      3.4   CRITICAL SERVICE LEVEL KVM PERFORMANCE COMPUTATION METHOD
            The formulas defined in sections 3.4.1 through 3.4.6 below shall
            apply to the computation of the Critical Service Level KVMs, as
            applicable for each Line of Business separately.
            Upon completion of Modernization, the Critical Service Level KVM
            computation methods shall be reviewed by the parties for each BCH
            Company separately, with the objective of improving such methods.
            3.4.1 BILLING ACCURACY
                  A.  The Number of Total Bills, [**], less the Number of
                      Mistakes, [**], divided by the Number of Total Bills for
                      the same Line of Business, over a [**] period. This result
                      (%)
                                     - 18 -
                      shall be compared against the relevant Target KVM %,
                      Bonus % Threshold, and Penalty Rebate % Threshold.
                  B.  If the result is equal to or lower than the relevant
                      Penalty Rebate % Threshold, the Performance Penalty
                      Rebate's dollar value shall be calculated as per Section
                      3.3 above.
                  C.  If the result is equal to or higher than the relevant
                      Bonus % Threshold, the Bonus's dollar value shall be
                      calculated according to Section 3.3 above.
            3.4.2 DELIVERY BY DAY [**] (for ▇▇▇▇ Canada or such lesser/other
                  time period for the other Lines of Business as set out in this
                  Exhibit)
                  A.  The Number of Total Bills actually delivered, [**], less
                      the number of bills billed after the end of DAY [**] (or
                      such lesser/other) time period as mentioned above),
                      divided by the Number of Total Bills actually delivered
                      [**], over a [**] period. This result (%) shall be
                      compared against the relevant Target KVM %.
                  B.  If the Target KVM % is met earlier than DAY [**] (or
                      such lesser/other time period as mentioned above),
                      Certen is eligible for a Bonus.
                  C.  The dollar value of the Bonus for each day earlier than
                      DAY [**] (or such lesser/other time period as mentioned
                      above) will be as provided for in Section 3.3 above.
                  D.  If the Target KVM % is met later than DAY [**] (or such
                      lesser/other time period as mentioned above), the BCH
                      Companies will be eligible for a Performance Penalty
                      Rebate resulting from Certen's failure to meet a Critical
                      Service Level KVM, as provided for in Section 3.3 above.
            3.4.3 PAYMENT RECEIVED & PROCESSED SAME DAY
                  A.  The Total Number of Payments Received Over [**] Period,
                      [**], less the Sum of the Failed Same Day Processing Over
                      [**] Period, [**], divided by the Total Number of Payments
                      Received Over [**] Period. This result (%) shall be
                      compared against the relevant Target KVM %, Penalty Rebate
                      % Threshold, and Bonus % Threshold.
                                     - 19 -
                  B.  If the result is equal to or lower than the relevant
                      Penalty Rebate % Threshold, the Performance Penalty
                      Rebate's dollar value shall be calculated according to
                      Section 3.3 above.
                  C.  If the result is equal to or higher than the relevant
                      Bonus % Threshold, the Bonus's dollar value shall be

      3.6   PROCESS FOR CORRECTION AND ANALYSIS
            3.6.1 NEGATIVE FACTOR CORRECTION
                  In the event that the parties mutually determine that certain
                  Critical Service Level KVM factors as determined by the [**]
                  to the Agreement, shall have a material negative impact on the
                  one of the Critical Service Level KVMs' measured values, then
                  the parties shall designate the problem as a "Negative
                  Factor", and then the parties shall proceed as follows:
                                     - 20 -
                           A.   The BCH Companies and Certen shall promptly form
                                a joint team to determine corrective action.
                                Certen shall be responsible for initially
                                determining what remedial actions are to be
                                taken, but shall consult with the BCH Companies
                                as to such course of action. If the cause of the
                                problem is substantially outside of Certen's
                                responsibility and control, then Certen and the
                                BCH Companies shall mutually agree on the
                                corrective action, subject to the requirements
                                of Exhibit G (Change Order Process).
                           B.   If the cause of the Negative Factor is due to
                                factors substantially within Certen's
                                responsibility and control:
                                1.      Certen shall implement the remedial
                                        action and correct the Negative Factor
                                        as soon as reasonably possible, taking
                                        into account the urgency of the
                                        situation and the appropriate staff for
                                        the job.
                                2.      Certen shall determine and keep a
                                        designated representative of the BCH
                                        Companies advised at all relevant times
                                        of the [**] Negative Factor resolution
                                        and resumption of operations.
                                3.      The BCH Companies shall develop a
                                        business communications plan, and Certen
                                        shall provide such assistance and
                                        cooperation as may be reasonably
                                        necessary to enable the BCH Companies to
                                        develop and implement such a plan.
                                4.      The joint team shall monitor progress on
                                        resolution of a Negative Factor and
                                        update the communications plan. If the
                                        Negative Factor is not resolved within
                                        the estimated time frame, then the joint
                                        team will reassess what further or
                                        different corrective action may be
                                        required.
                                5.      Each of Certen and the BCH Companies
                                        must sign-off and agree on the final
                                        resolution of the Negative Factor.
                  3.6.2    PERFORMANCE REVIEW PROCESS
                           In the event that:
                           A.   any one of the actual Critical Service Level
                                KVMs achieved and measured by Certen during the
                                previous [**] period fail to meet the relevant
                                prescribed Critical Service Level KVMs and
                                Penalty Rebate % Threshold, subject to Section
                                3.8 below; or
                                     - 21 -
                           B.   a Negative Factor (the cause of which is
                                substantially within Certen's responsibility and
                                control) is declared by the parties during the
                                previous [**] in accordance with Section 3.6.1
                                above, subject to Section 3.8 below, then a
                                Performance Review process, which incorporates
                                the following steps, will be triggered:
                                1.      Certen shall conduct a Post Mortem
                                        analysis and review the results with the
                                        BCH Companies;
                                2.      [**], following the review, Certen
                                        shall, [**], develop and implement
                                        corrective actions and/or modify
                                        existing processes and procedures or
                                        create new processes and/or procedures
                                        to prevent any recurrence and when this
                                        is not reasonably possible, then Certen
                                        shall prepare and submit to the BCH
                                        Companies a plan indicating how and when
                                        any such action, process or procedure
                                        will be in place to prevent any
                                        recurrence;
                                3.      If a contributing cause of a problem or
                                        delay in implementing a remedy to a
                                        problem was substantially within the
                                        control of a third party, then the
                                        parties shall determine a course of
                                        action to prevent a recurrence; and,
                                4.      The BCH Companies and Certen will sign
                                        off on the conclusions resulting from
                                        the review process.

                           Bell shall have the right to terminate the Agreement
                           by giving notice of termination to Certen without

                           set out in Section 18.2 thereof, if Certen causes,
                           subject to Section 3.8 above:

III. GRACE PERIODS
   The Parties have agreed that for certain specified time periods based on
   calendar days (each a "Grace Period") Certen's obligation to perform the
   Services in accordance with some or all of the PMs will be suspended (such
   KVMs/SLs referred to hereinafter as the "Suspended PM") upon the occurrence
   of certain events that the Parties recognize will negatively impact Certen's
   ability to perform the Services in accordance with the PM ("PM Suspension
   Events"). A "Suspended PM" means the KVM, if applicable, will not draw a
   bonus or penalty during the Grace Period. Certen shall be required to perform
   the Services measured by such Suspended PM, and measure and report on its
   performance against each Suspended PM, in a timely, accurate and professional
   manner. Set forth below is a table summarizing the PM Suspension Events and

IV.   PENALTY REBATE/BONUS PAYMENT SCHEDULE FOR KVMS
   NOTE: From the Amendment Effective Date, Bell has agreed to [**] the Penalty
   Rebates/Bonuses calculation. Bell is permitted during the Term, by giving
   Certen [**] prior written notice to [**] the Penalty Rebates/Bonuses
   calculation hereunder. Accordingly, the following provisions relevant to
   Penalty Rebates/Bonuses calculations will only apply [**] Bell.
   Actual payment or crediting of accumulated Penalty Rebates/Bonuses will be
   made at the time that the BCH Companies' final payment in respect of an
   Operational Year is due and payable under the Agreement. Penalty
   Rebates/Bonuses are calculated [**] by multiplying [**] by the [**] (as
   defined in Exhibit B to this Agreement) for Services received by Certen
   associated with the applicable [**] generating the Penalty Rebate/Bonus
   during the [**] in which the Performance Penalty Rebate/Bonus is
   incurred/earned. Penalty Rebates/Bonuses shall not be applied under both
   Exhibit C-2 and Exhibit C-1 for the same Miss.
   If the aggregate of all Penalty Rebates due to the BCH Companies within a
   particular Operational Year less the aggregate of all Bonuses due to Certen
   from the BCH Companies in the same Operational Year is positive, Certen will
   credit the BCH Companies with the amount calculated, which credit shall be
   applied to the Fees chargeable by Certen commencing in the next Operational
   Year, and all Penalty Rebate/Bonus balances for the BCH Companies will be
   reduced to zero for the next Operational Year.
   If the aggregate of all Penalty Rebates due to the BCH Companies within a
   particular Operational Year less the aggregate of all Bonuses due to Certen
   from the BCH Companies in the same Operational Year is negative, then the
   Penalty Rebate balance will be reduced to zero, while the amount calculated
   (i.e., the difference of Bonuses minus Performance Penalty Rebates) will be
   carried forward as an opening Bonus for the next Operational Year.
   With respect to the last Operational Year of the Agreement (or any portion
   thereof if such Operational Year is not a full twelve (12) calendar months),
   any outstanding amount due to Certen (i.e., the amount equal to the aggregate
   Bonuses minus aggregate Penalty Rebates for that Operational Year or portion
                                       -3-
   thereof), will be paid by the BCH Companies up to (but not exceeding) an
   amount equal to the aggregate sum of all Penalty Rebates credited to the BCH
   Companies at the end of all previous Operational Years of the Agreement.
V.    MECHANISM FOR PENALTY REBATES OR BONUSES
   1.  ALLOCATION OF PENALTY REBATES
   A. Certen will issue [**] Penalty Rebates to the applicable BCH Company, at
   the dollar value calculated in accordance with the applicable Penalty Rebate
   Threshold, if Certen Misses the KVM for [**] in an Operational Year. The
   dollar value will be calculated using the [**] attained during the [**]
   period.
   B. After issuing [**] Penalty Rebates to the applicable BCH Company in
   accordance with Paragraph 1A above, Certen will issue [**] Penalty Rebate to
   the applicable BCH Company, at the dollar value calculated in accordance with
   applicable Penalty Rebate Threshold, if Certen Misses the KVM (upon which the
   [**] Penalty Rebates issued under Paragraph 1A above were based) for the [**]
   in any other [**] of that Operational Year.
   2.  ALLOCATION OF PERFORMANCE BONUSES
   ▇. ▇▇▇▇ will issue [**] Bonuses, at the dollar value calculated in accordance
   with applicable Penalty Rebate Threshold, if Certen meets or exceeds the
   Bonus % Threshold for the same KVM for the [**] for [**] in an Operational
   Year. The dollar value will be calculated using the [**] attained during the
   [**] period.
   B. After issuing [**] Bonuses to Certen in accordance with Paragraph 2A
   above, Bell will issue [**] Bonus to Certen, at the dollar value calculated
   in accordance with applicable Penalty Rebate Threshold, if Certen meets or
   exceeds the Bonus % Threshold (upon which the [**] Bonuses issued under
   Paragraph 2A above were based) for Certen in any other [**] of that
   Operational Year.
   3.  OPERATIONAL YEAR ADJUSTMENT
   For the purposes of this Section only, the calculation of [**] in an
   Operational Year shall include the [**] of the prior Operational Year. That
   is, if Certen Misses, meets or exceeds (as applicable) KVMs in the [**] or
   [**] (as applicable) of an Operational Year and in the [**] (as applicable)
   of the next Operational Year, then, where there are Misses for [**], the
   Performance Penalty Rebate or Bonus (as applicable) will apply to any [**] in
   the new Operational Year where the KVM is Missed, met or exceeded (as
   applicable).
   4.  TRANSITION-OUT PERIOD
   The KVMs shall [**] upon commencement of, and throughout, the Transition-Out
   Period. Subject to and without limiting the foregoing, Certen will [**] meet
   the KVMs during the Transition-Out Period.
VI.   [**] REPORTS
   On a [**] basis, Certen shall provide a written report to Bell which includes
   the following information (the "[**] Measures Report"): (i) Certen's
   quantitative performance for each KVM/SL; (ii) each Individual KVM/SL BGYR
   State and the overall KVM/SL Score; (iii) a "root-cause analysis" and
   corrective action plan with respect to any KVM/SL where the Individual KVM/SL
   BGYR State was "Red" during the preceding [**]; and (iv) trend or statistical
   analysis with respect to each KVM/SL as requested by Bell. The [**] Measures
   Report shall be due [**]. Separate reports will be generated for each
   platform Line of Business (LOB) applicable.
                                       -4-
VII.  REVIEW AND CHANGE PROCESS
      PMs are subject to review on the following occasions throughout the Term:
-     OPTIONAL [**] REVIEW: Within [**] months of the Amendment Effective Date
      and every [**] thereafter, the Parties will have the option to meet and
      review the PMs.
-     ANNUAL REVIEW: Certen and Bell shall set a mutually agreed date to conduct
      annual reviews of the PMs and Certen's performance with respect to the
      PMs. At a minimum, the annual review will include:
            -     Comprehensive review of the previous year's performance;
            -     Revision of the PMs, if any, based upon mutual written
                  agreement; and
            -     The methods of measurement, targets and thresholds,
                  credit/bonuses procedures, and any other relevant parameter,
                  mechanism or portion of this Exhibit C-2.
   No changes to any PM shall become effective without the written approval of
   each Party's Operational Prime (as defined in Exhibit F) Committee members.
   Upon the written mutual consent of the Parties and in accordance with Exhibit
   G (Change Order Process), the Parties shall adjust any part of the PMs and/or
   Penalty Rebates/Bonuses. The Parties shall prepare SL documents, defining the
   parameters of SLs, which documents are external to this Exhibit. Such
   documents may be altered by the mutual determination of the Parties upon
   written agreement of each Party's responsible Service Level Coordinator and
   Service Level Manager.

Measurement     Normally a [**] with the exception of Grace Periods or
Period          other exclusions.
Steady State    Means the systems and the data have been set up and are
                running in production at the original or a new "permanent" site
                as agreed to by both Parties following a Disaster. The upstream
                and downstream interfaces are accessible and data operations are
                running as per the Certen BC/RP (Business Continuity/ Resumption
                plan), if available.
Severity Level  The system, component or application is down or unusable
1               resulting in a complete loss of service, [**] Critical
                deliverables, schedules and business operations will be
                impacted.
                Incidents are worked continuously and escalated to other
                technical personnel and management as required until service is
                restored via a workaround or fix resulting in the problem being
                either closed or downgraded.
Severity Level  The system, component or application is functioning
2               poorly. The response from the system, component or
                application results in a degraded service, [**]. Critical
                deliverables and schedules will be impacted but to a lesser
                extent than a Severity 1 The result negatively impacts some
                business operations.
                Incidents are worked on and assigned to other technical
                personnel and management as required during extended business
                hours (as defined in the SL Agreement for the applicable
                application) until service is restored via a workaround or fix.

Thresholds      The same thresholds that apply to the SLs under the Legacy
                Systems will be applied to the SLs under the Modernized Systems.
                For new KVMs and SLs the following process is be observed:
                Certen will collect measurement data for [**]after the Amendment
                Effective Date, after which time the Parties will within [**],
                negotiate in good faith, a set of on-going measures and
                thresholds.
IX.   DEPENDENCIES
   The following events, should they occur, shall not be included in the
   calculation of Certen's performance in relation to the KVMs/SLs (and
   accordingly, no Penalty Rebates shall result from such events), but shall be
   reported in writing to the BCH Companies, on a [**] basis from the Amendment
   Effective Date, in a format to be defined and agreed to by the parties:
   (a) A Force Majeure Event (as defined under the Agreement);
   (b) A failure resulting from the acts or omissions of (a) [**]; (b) [**];
   or (c) [**] BCH Companies or to Certen;
   (c) A failure of one of the BCH Companies ([**]) to fulfill its (or their)
   part in the Services, according to the dependencies of the parties set forth
   in Exhibit A, or the roles and responsibilities of the parties set forth in
   Exhibits O-1 and O-2 of the Agreement (or the dependencies and/or roles and
   responsibilities set forth in such third party contracts referenced in
   paragraph (b) above);
   (d) A failure arising out of an error or defect in the Legacy Systems and/or
   Modernized System, not caused by Certen or any third party under Certen's
   responsibility, control and management; or
   (e) Exceeding Envelope Parameters that are indicated in Exhibit A as being
   dependencies for specific KVMs/SLs;
X.    REMEDIES FOR MISSES
   [**] SUCCESSIVE OR AGGREGATE MISSES OF KVMS
   A. Subject to Section IX (Dependencies) above, in the event that Certen
   causes an aggregate of [**] Misses of the same KVM for the same Line of
   Business, [**] then, subject first to compliance with the Dispute Resolution
   procedures set forth in Section 18 of the Agreement, and further subject to
   the limitation of liability provisions of the Agreement, Certen shall credit
   the BCH Companies in the amount [**]. No Penalty Rebates/Bonuses or damages
   shall apply to Misses of SLs.
   B. All Penalty Rebates previously credited to the BCH Companies under this
   Exhibit C-2 shall be deducted from [**]. The BCH Companies shall not have
   grounds for termination of the Agreement based on the successive or aggregate
   Misses described in this Section, subject to the occurrence of a Material
   Breach (defined below).
   MATERIAL BREACH
   Subject to the following-
   (i) compliance with the Dispute Resolution procedures set forth in Section
   18.1 of the Agreement; and
   (ii) if, following such procedures, corrective measures are not taken, the
   Parties shall attempt to resolve
                                       -7-
   the dispute within an additional period of [**] in which they shall refer the
   dispute to the Parties' executive officers; and
   (iii) the limitation of liability provisions of the Agreement,
   ▇▇▇▇ shall have the right to terminate the Agreement by giving notice of
   termination to Certen without Certen having prior recourse to the arbitration
   procedure set out in Section 18.2 thereof, if Certen causes, subject to
   Section IX (Dependencies) above:
   1. [**] successive Misses of the same KVMs for the same Line of Business
   within[**]; and
   2. each of such Misses materially deviates from the applicable Penalty Rebate
   Threshold ("Material Deviation");  and
   3. the [**] consecutive Misses, taken as a whole, have materially adversely
   affected the delivery of the Services under the Agreement;
   provided, however, that Certen shall have the right to dispute, pursuant to
   the provisions of Section 18.2 of the Agreement, such termination after the
   effective date of the termination as set out in the termination notice.
   The parties undertake to negotiate in good faith, as soon as practicable
   following the Amendment Effective Date and in any event by [**] measurements
   of the Material Deviation threshold for purposes of measurement of Material
   Deviation as of the Amendment Effective Date.
XI.   COMPUTING THE MEASUREMENT SCORE (ROUNDING)
The measured result for each measure may require rounding in order to align with
the defined scoring criteria. Where applicable, a simple rounding practice will
be used. Two-decimal place accuracy will be used as the rounding precision,
unless otherwise specified.
SAMPLE CALCULATION:
             Using the Online Availability SL measured result: [**]%
Apply the following SL scoring matrix:
   Individual SL          Production
     BGYR State           Environment
                     GE = Greater than or
                           equal to
                        LT = Less than
                  
       Blue               GE [**]%
       Green               GE [**]%
       Yellow              GE [**]%
        Red                 LT [**]%
The rounding algorithm for this sample employs two-decimal place accuracy. The
measurement result after rounding is [**]%, which yields a Green score.

                         (IT OPERATIONAL SERVICE LEVELS)
This section of the document lists the type of the IT Operational SLs Certen
will provide; the individual measurements are recorded in external "Service
Level Agreement" documents. Versions of the external "Service Level Agreement"
documents are to be maintained and mutually agreed upon by both Parties and
version history shall be maintained.
The Parties will define, clarify and determine the values and measurements for
the following IT Operational Service Levels and the other terms of this Appendix
III by negotiating the same in good faith as soon as practicable following the
Amendment Effective Date and, in any event, by [**]
1.0 ONLINE AVAILABILITY
            1.1 OPERATIONAL MEASURE
            Specification: Online Availability
            Definition:    Online Availability shall be calculated by
                           subtracting [**]Time, as described below, during the
                           Measurement Period from the [**], as described below,
                           in the Measurement Period, dividing this amount by
                           the total number of [**] in the Measurement Period,
                           and multiplying the resulting decimal by 100.
                           [**] are the number of minutes elapsed
                           outside the maintenance period. [**] (i.e.,
                           [**]) shall be calculated as follows for all
                           but the last calendar day of the [**]:
                           Outage exemptions from the SL formula are handled
                           case-by-case. Certen shall maintain a list of
                           authorized "requestors" for outages, and similarly
                           ▇▇▇▇ shall maintain a list of authorized "approvers"
                           who review and grant outage approvals and exemptions
                           as applicable.
            Special        The time associated with Testing or
            Exclusions:    Alterations to the Production System, during
                           normal online hours, by ▇▇▇▇ will be excluded.
                           ▇▇▇▇ equipment or system failures that impact the
                           Certen systems will be excluded unless the failure is
                           caused by Certen. For example: the ICN network is
                           under ▇▇▇▇'▇ control.
                           Note: An [**] of maintenance per Build, shall
                           be allowed for periodic Builds to be placed
                           into the Production Environment as required.
                           These Build installations must be scheduled
                           and approved in advance by ▇▇▇▇.

2.0   ONLINE RESPONSE TIME
            2.1. OPERATIONAL MEASURE
             Specification: Online Response Time
             Definition:    The amount of time required for a requested
                            Transaction to be completed.
                            This SL applies to that portion of transaction
                            processing for which Certen is responsible.
                            [Demarcation lines and values TBD]
                            [User Response time" definition refers to the
                            transaction processing time from when a request is
                            received by the Certen environment to when it is
                            released back from its environment. The environment
                            includes the servers which make up the Solution.
                            The Online Response Time percentage is derived by
                            dividing the [**] that occurred within the
                            threshold, by the [**] and multiplying the result by
                            100.
             Special        A small number (x% of the best and x% of the
             Exclusions:    worst) transaction times shall be excluded from
                            the calculation for this SL in order to remove
                            statistical anomalies.
                            ▇▇▇▇ and Certen agree to mutually review and where
                            appropriate agree to exclude anomalous transaction
                            time measurements during each Measurement Period.
                            Maintenance Periods - Online response time
                            measurements will not be collected during agreed
                            upon maintenance periods.
                            Online response time will not be collected during
                            availability outages.
                            Online Response Time calculation shall exclude
                            measurement of transaction time that passes through
                            Third Party interfacing systems in situations where
                            ▇▇▇▇ is responsible for the relationship with the
                            Third Party. In such transactions, Certen shall
                            measure, and this SL shall apply to, only the
                            portion of the transaction for which Certen is
                            responsible.
3.0 SERVICE RESPONSE TIME
             Specification: Service Response Time
                                      -18-
             Definition:    The time Certen has to acknowledge tickets
                            from the various Severity Levels.  Certen
                            and ▇▇▇▇ shall jointly agree, acting
                            reasonably, to reprioritize Issues for
                            resolution and for SL measurement from time
                            to time, acting reasonably. Acknowledgement
                            of tickets by Certen will occur by way of a
                            system generated auto reply, or verbal or
                            other electronic means of communication.
                            The time interval shall be measured from the time
                            the [**] until the time at which the end user
                            receives [**]
                            The Service Response Time percentage is derived by
                            dividing the number of tickets that missed the
                            threshold by the total number of tickets and
                            multiplying the result by 100.
4.0 SERVICE RESOLUTION
             Specification: Service Resolution
             Definition:    Certen's unencumbered time to repair each Issue
                            during the Measurement Period.  The measurement
                            time for this SL begins when [**].  The
                            measurement time ends when the repair is
                            implemented or scheduled in accordance with the
                            parties' joint consent, for implementation in
                            production.  Certen ticketing measures
                            unencumbered time automatically on the basis of
                            status inputs by Certen' Help Desk personnel,
                            and the resulting data is made available in the
                            [**] end reporting.
                            Certen and ▇▇▇▇ shall jointly agree to reprioritize
                            incidents for resolution and for SL measurement,
                            acting reasonably.
                            Priority breakdown needs to be clear.
                            The Service Resolution Time percentage is derived by
                            dividing the number of tickets that missed the
                            threshold by the total number of tickets and
                            multiplying the result by 100.

3     COMPLETED PROJECTS
      The Completed Projects are set forth in Annex 1 attached to this Exhibit
      D.
4     SCOPE, ESTIMATED BUDGETS AND ESTIMATED TIMETABLES OF OUTSTANDING PROJECTS
      FOR THE BCH COMPANIES
4.1   [**] PROJECT
      The Scope (defined below), estimated schedule and estimated 2003 budget
      for the Project known as [**] together with the work and services to be
      performed in respect thereof are set out in Annexes 2 and 3 to this
      Exhibit D (the "[**] PROJECT"). Certen shall perform the work and services
      comprising the [**] Project in accordance with the terms of this Exhibit
      D, and the Master License and Services Agreement including Exhibit O-1
      attached thereto. For the avoidance of doubt all amounts referred to
      herein are in Canadian dollars.
      (i)   Scope: The scope of the [**] Project consists of [**] (the "Scope").
            Any [**] the Scope, [**] the Scope. For example, a [**] and [**]
            existing
                                       3
            Scope, [**] and therefore [**] to the existing Scope.
      (ii)  Budget: The estimated total 2003 budget which has been spent since
            January 1, 2003 or which is available to be spent on the [**]
            Project, which has been estimated as of June 18, 2003 on the basis
            of assumptions detailed in the budget and the estimated schedule
            attached as Annex 3 and the Scope as defined in Annex 2, is $[**] in
            accordance with the items detailed in Annex 3 attached to this
            Exhibit D (the "TOTAL AMOUNT"). The Total Amount is divided into (i)
            Certen costs of $[**] which reflects amounts to be expended or costs
            to be incurred by Certen (the "CERTEN COST"), and (ii) $[**] which
            reflects amounts to be expended or costs to be incurred by the BCH
            Companies (the "NON-CERTEN COSTS"). The breakdown of costs between
            the BCH Companies and Certen reflects a credit payable in accordance
            with the terms of Exhibit B to this Agreement, by Certen to ▇▇▇▇
            relating to the Oversight Functions associated with the [**]
            Project. The Certen Costs have been fully funded as of the Amendment
            Effective Date by the Parties (and/or their Affiliates) in
            accordance with Annex 3.
      (iii) Timetable: The key milestones of the [**] Project are set out in
            Annex 3, including the targeted launch date ("TARGET LAUNCH DATE")
            of [**] for operating [**] in production and beginning normalization
      (iv)  Budget and Timetable Overruns- Added Scope:
            With respect to any increase in the budget/costs/expenditures beyond
            the Total Amount that is due to items that ▇▇▇▇ requests to add to
            the Scope (whether or not such items cause a delay in the Actual
            Launch Date past the Target Launch Date):
            (a)   [**]; and
            (b)   [**].
            For the avoidance of doubt, [**].
      (v)   Budget and Timetable Overruns - Delays
            If there are any delays to the [**] Project which are not due to
            items that ▇▇▇▇ requests to add to the Scope , and which postpone
            the actual date on which the [**] Project is put into production
            ("Actual Launch Date") past the Target Launch Date, and which result
            in additional expenditures and costs not covered by the Total Amount
            and if ▇▇▇▇ determines to continue performance of the [**] Project
            beyond the Target Launch Date, then such additional
                                       4
            expenditures and costs resulting from such delays shall be dealt
            with as follows:
            (a)   [**];
            (b)   [**];
            (c)   [**];
            (d)   [**]; and
            (e)   [**].
            (f)   [**]
                  No amounts payable by ▇▇▇▇ under Sections 4.1(v)(d) or (e)
                  [**]
            (g)   Roles and Responsibilities
                  The [**] Project shall continue, after the Amendment Effective
                  Date, to be managed under the same management structure and
                  roles and responsibilities framework that were in place prior
                  to the Amendment Effective Date. [**]
                                       5
                  For the avoidance of doubt, [**]
                  (vi)     Budget and Timetable Overruns - Other
                  Until the Actual Launch Date (whether or not it was delayed

            time BCH or Certen declares a Disaster. If the BCH Companies or
            Certen declares a Disaster and the Recovery Centre is not available,
            Certen shall make available another recovery centre or another
            processing facility of Certen or any of its Affiliates (to be
            determined by Certen, with the BCH Companies' approval);
      2.4   Certen shall allow the BCH Companies access to the Recovery Centre
            in order to perform tests in accordance with the Disaster Recovery
            Procedures. In the event that another customer of Certen has
            declared a Disaster which reasonably prevents the BCH Companies from
            performing such tests, Certen may, in its reasonable discretion,
            reschedule the BCH Companies' test time in order to accommodate the
            other customer;
      2.5   If any Party wishes to make any change to the configuration of the
            Recovery Centre, it shall do so in accordance with the Change Order
            Process. If the change involves upgrade or replacement of Hardware,
            Certen shall install the Hardware within [**] the date the
            applicable Change Proposal was accepted by the BCH Companies in
            accordance with the Change Order Process. If the BCH Companies or
            Certen declares a Disaster prior to the expiry of the [**] period
            and the applicable Hardware has not yet been installed, Certen shall
            use commercially reasonable efforts to find alternate Hardware or to
            expedite the installation;
      2.7   Certen will provide basic working space at the Recovery Centre for
            the BCH Companies' use during testing or upon declaration of a
            Disaster;
      2.8   To assist the BCH Companies during the restore process after a
            Disaster has been declared or during a test by the BCH Companies,
            Certen shall perform [**] at the Recovery Centre; and
      2.9   Certen will provide the appropriate disaster recovery skills and
            expertise including operational assistance, technical assistance and
            problem determination assistance while the BCH Companies are using
            the Recovery Centre.
3.0   BCH COMPANIES RESPONSIBILITIES
      The BCH Companies shall:
      3.1   perform their obligations, as set out in the Disaster Recovery
            Procedures;
      3.2   comply with any additional Recovery Centre procedures, including
            those relating to safety and security;
                                     - 9 -

                                    EXHIBIT K
                         SECURITY, ACCESS AND INTERFACE
1.    GENERAL
Subject to the terms and conditions of this Exhibit, Certen will continue to
perform or cause to be performed, the same or substantially the same security
functions provided by the BCH Companies, or any third party on their behalf,
just prior to the Effective Date, including those security functions listed in
Appendix 1, and such other security functions set out in this Exhibit K, at any
facility where the Services are performed under this Agreement (all in a manner
consistent with contracts with subcontractors, such as [**] and ▇▇▇▇, in effect
prior to the Amendment Effective Date which are to be used by, or transferred
to, Certen in accordance with the Agreement).
2.    DEFINITIONS
In this Exhibit K, unless the context otherwise requires, all capitalized terms
shall have the meaning ascribed thereto in the body of the Agreement or in this
Exhibit, as the case may be. In addition, the following words and terms shall
have the following meanings:
2.1   "BCH COMPANY DATA" means all data, information and materials relating to
      any BCH Company or any supplier, licensor, customer, contractor,
      consultant or agent of any BCH Company contained in any form, including
      data files, records, notes, correspondence or other materials or
      information, provided to Certen or its Affiliates or any contractor,
      consultant or agent of Certen or its Affiliates pursuant to or relating to
      this Agreement or the provision of Services.
2.2   "OPERATIONAL PRIME" has the meaning set forth (and is identified) in
      Exhibit F (Governance).
3.    ACCESS AND SECURITY
3.1   All BCH Company Data shall be and remain the exclusive property of the BCH
      Company to which it relates or such BCH Company's suppliers or licensors,
      as the case may be. Except as otherwise provided under this Agreement, the
      BCH Companies shall be permitted electronic access to BCH Company Data (i)
      at all times for use by BCH Company "End Users" (as defined in this
      Section 3.1 below) in the normal course of business, using the relevant
      application utilized for such purpose, and (ii) within a reasonable period
      of time following receipt by Certen of a request by the BCH Companies (and
      in any event, unless otherwise agreed by the Parties, within [**] of such
      receipt) for any access other than access by an End User (the
      circumstances of such access by a BCH Company representative, including
      the arrangements for monitoring by Certen personnel, to be coordinated in
      advance), which access, in each case, shall not be restricted except where
      restrictions on access are required by other provisions in this
                                     - 2 -
      Agreement, scheduling requirements, or by a period of repair or
      maintenance provided for in this Agreement. Certen shall be [**] to the
      extent caused by the BHC Companies' requirements for access pursuant to
      Section 3.1(ii), other than access required to address a failure of Certen
      to perform its obligations under this Agreement. "End Users" shall mean
      those Persons determined by the BCH Companies to require access to BCH
      Company Data in the normal course of business. Certen shall not:
      (a)   possess or assert any ownership right, encumbrance or similar right
            in the BCH Company Data; or
      (b)   sell, disclose, copy, assign, lease or otherwise dispose of, or
            commercially exploit, any BCH Company Data, even in the event of a
            Dispute between the Parties or upon the termination or expiration of
            the Term or any Final Transition-Out Period, without the appropriate
            BCH Company's prior written consent thereto.
3.2   Upon written request by ▇▇▇▇ at any time or upon the termination or
      expiration of the Term or any Final Transition-Out Period, as defined in
      Exhibit J, Certen will return to ▇▇▇▇ or its designee all BCH Company Data
      (or, in the case of a written request by the BCH Companies, all of the BCH
      Company Data referred to in such request) in all of Certen's then existing
      machine readable formats (or other machine readable format reasonably
      requested by ▇▇▇▇) and media types and related Application Software (for
      which the BCH Companies have a license under the Agreement) necessary for
      the applicable BCH Companies to efficiently use their data with the
      applicable systems. Certen will also securely erase (e.g., delete/format
      and securely overwrite) any BCH Company Data from any hardware, media or
      other material within its control that is to be no longer used in
      connection with the provision of the Services, provided that Certen will
      not erase any BCH Company Data from any Hardware, media or other material
      that is to be sold, leased or otherwise made available to the BCH
      Companies or their designee upon the termination or expiration of this
      Agreement or of any Final Transition-Out Period.
3.3   At no time will any of the computer or other files or other materials or
      information containing BCH Company Data be stored or held in a form or
      manner not accessible to the BCH Companies in accordance with Section 3.1
      above. Subject to restrictions contained in any relevant contracts, Certen
      will provide to ▇▇▇▇'▇ Operational Prime or such other Person or Persons
      as may be designated in writing by ▇▇▇▇ all such files and other materials
      promptly upon the request of ▇▇▇▇, including [**] (if any) and any other
      specification or information necessary for ▇▇▇▇ or any BCH Company to
      retrieve, read, revise and/or maintain such files and information. Upon
      the request of ▇▇▇▇'▇ Operational Prime, Certen will certify, to the best
      of its knowledge, information and belief, the completeness of all files
      and other information provided to ▇▇▇▇ or any BCH Company and that no
      material element, amount or other fraction of such files or other
      information to
                                     - 3 -
      which ▇▇▇▇ may, acting reasonably, request access or review has been
      deleted, withheld, disguised or encoded in a manner inconsistent with the
      purpose and intent of providing access to any BCH Company as contemplated
      by Section 3.1 of this Exhibit and otherwise in this Agreement.
3.4   Certen shall, at all times:
      (a)   meet and enforce the BCH Companies' physical and logical access
            control policies, standards and procedures for all BCH Company
            environments under its management and control, provided that such
            policies, standards and procedures, and any amendments thereto, are
            provided to Certen by the BCH Companies immediately upon the
            adoption by the BCH Companies of such policies, standards and
            procedures;
      (b)   protect the BCH Companies' proprietary information, including, but
            not limited to, customer and employee data and information;
      (c)   screen and security clear its employees in accordance with the
            policies of Amdocs, provided that such policies from time to time
            are at least as stringent as (i) those Amdocs policies in effect as
            of the Amendment Effective Date, and (ii) those policies applied by
            Certen as of the Amendment Effective Date;
      (d)   give the BCH Companies, acting reasonably, access, accompanied by
            Certen's designated personnel, in accordance with Section 23 of the
            Agreement, to the applicable Applications Software or Systems used
            by Certen, for the benefit of the BCH Companies, for the purpose (i)
            of conducting security reviews of such Applications Software or
            Systems and BCH Company Data only, and (ii) of ensuring compliance
            with BCH Companies corporate security policies and standards;
      (e)   maintain adequate audit trails for all security-related functions
            and tasks in which Certen is involved;
      (f)   research and respond to actual and threatening security problems on
            all BCH Companies environments under its management and control and
            report such problems promptly to ▇▇▇▇. ▇▇▇▇ shall provide to Certen
            the name and contact information of the applicable authorized ▇▇▇▇
            representative in this regard;
      (g)   provide incident investigation support to BCH Companies;
      (h)   provide Applications Software security support and consulting as may
            be reasonably requested by BCH Companies to the same extent such
            support and consulting services were provided by ▇▇▇▇ prior to the
            Effective Date; if the BCH Companies' requirements in respect of
            such support and
                                     - 4 -
            consulting services change in a manner which results in increased
            costs to Certen then any such change, together with additional fees,
            if any, in respect thereof, shall be dealt with in accordance with
            the Change Order Process;
      (i)   hold all BCH Company Data segregated [**] from that of any other
            entity to which Certen provides services; upon reasonable request,
            not to exceed [**], Certen shall provide satisfactory evidence to
            the BCH Companies that the BCH Company Data is held in accordance
            with the foregoing requirement. Notwithstanding the foregoing, ▇▇▇▇
            may additionally request, upon providing Certen with reasonably
            satisfactory evidence that BCH Company Data may not have been
            segregated in accordance with the foregoing, and Certen shall
            provide, additional satisfactory evidence to the BCH Companies that
            the BCH Company Data is in fact held in accordance with the
            foregoing requirement; and
      (j)   Certen shall ensure that the security features and standards of the
            Legacy Systems and Modernized Systems developed, implemented or
            operated by Certen for the BCH Companies, as well as the protection
            levels applicable to such Legacy Systems and Modernized Systems and
            BCH Company Data, meet the BCH Companies' security policies and
            procedures as provided to Certen from time to time. Certen shall
            provide the opportunity to ▇▇▇▇ to review Applications Software
            together with associated documentation at the appropriate stage of
            development in order to determine whether such security features,
            standards and protection levels as required by ▇▇▇▇ will be
            effectively implemented prior to the use of such Applications
            Software in production.
3.5   ▇▇▇▇ shall:
      (a)   retain authority and responsibility for:
            (i)   approval procedures with respect to access to BCH Company Data
                  together with all changes to such procedures;
            (ii)  [**];
            (iii) [**];
      (b)   notify Certen of any changes to the BCH Companies' security policies
            respecting security features, standards and protection levels that
            the BCH Companies may expect Certen to comply with. If Certen's
            compliance with any such change results in increased costs to
            Certen, the Parties shall address such costs through the Change
            Order Process.
                                     - 5 -
3.6   During the Term and any Final Transition-Out Period, Certen shall maintain
      recognized industry standard safeguards against the destruction,
      degradation, loss, disclosure or alteration of BCH Companies Intellectual
      Property and BCH Company Data in the possession or under the management of
      Certen or the destruction or alteration of any component of the System,
      which safeguards shall be the same, or substantially the same, as those
      employed by the BCH Companies, or any third party on their behalf, just
      prior to the Amendment Effective Date, and any additional computer
      security policies and procedures employed prior to the Amendment Effective
      Date which are contained in the Operations Procedures Manual if any. Such
      safeguards shall be continually updated, in accordance with Section 23.4
      of the Agreement (including with respect to reference made therein to
      possible additional costs which shall be addressed in accordance with the
      Change Order Process), including through the implementation of industry
      standard security software and other equipment in order to afford maximum
      protection to the System and the BCH Company Data in a commercially
      reasonable manner.
3.7   Certen personnel shall not attempt to access, or allow access to any data,
      files or programs within the IS environment to which they are not entitled
      under this Agreement. If such access is attained, Certen shall immediately
      report the incident to ▇▇▇▇'▇ Operational Prime, describe in detail any
      accessed materials and the method of access and, upon request, provide to
      ▇▇▇▇'▇ Operational Prime copies of any accessed materials.
3.8   Certen shall institute recognized industry standard system security
      measures to guard against the unauthorized access, alteration or
      destruction of Software, Intellectual Property, third party Software and
      BCH Company Data. Such measures with regard to the Legacy Systems shall be
      the same or substantially the same measures in place just prior to the
      Amendment Effective Date. System security measures for all Legacy Systems
      and Modernized Systems shall (i) require all users to enter a unique user
      identification code (ID) and password prior to gaining access to the
      Systems, and (ii) control user access to areas and features of the
      Systems. ▇▇▇▇ acknowledges that such security measures in respect of the
      Legacy Systems were in place immediately prior to the Amendment Effective
      Date.
3.9   If any BCH Company Data is lost or damaged as a result of the
      non-compliance by Certen, Certen employees, agents or subcontractors
      (other than [**] or [**]) with the terms or conditions of this Agreement
      including this Exhibit K, including the obligation of Certen to maintain
      safeguards against the destruction, loss, disclosure or alteration of BCH
      Company Data in the possession of Certen in accordance with Section 3.7,
      3.8, or 3.9 herein, Certen shall assist the BCH Companies in replacing or
      regenerating such lost or damaged data by providing any additional
      resources reasonably required by the BCH Companies without additional
      charge or expense (e.g., employee overtime) and shall not require the
                                     - 6 -
      BCH Companies to pay for any increased Certen resource usage resulting
      from the replacement or regeneration of such lost or damaged data.
3.10  Certen shall ensure that the ▇▇▇▇ Software, Intellectual Property and
      third party Software under its care are properly managed by using
      recognized industry standards.
3.11  For the avoidance of any doubt, the BCH Companies and any third party on
      their behalf shall not acquire any right in any data other than the BCH
      Company Data, and shall not be permitted to access any data within
      Certen's custody or control, including without limitation, data regarding
      services provided by Certen to third parties (collectively, the "CERTEN
      DATA"), other than the BCH Company Data and all in accordance with the
      provisions of Section 23 of the Agreement.
3.12  To the extent that any portion of the Certen Data resides on any systems
      of the BCH Companies, which are under the custody or control of the BCH
      Companies, Certen shall be permitted to access such Certen Data under the
      same terms and conditions applicable to the BCH Company Data, and such
      Certen Data shall be maintained by Certen in accordance with the same
      security measures applicable to the BCH Company Data, as set forth in this
      Section 3.
3.13  For so long as Certen [**] Certen shall [**] Certen [**] ▇▇▇▇ and Certen
      shall designate respective employees who shall be responsible to oversee
      all matters under this Exhibit and to interface with respect to such
      matters with the designated employee of the other Party.
3.14  Certen acknowledges that the security functions described in this Exhibit
      K [**] terms and conditions [**] and [**], Certen shall continue to be
      responsible for the provision of the security functions as set forth in
      this Exhibit [**].
4.    PHYSICAL SECURITY FOR FACILITIES
      Subject to Section 23 of the Agreement, Certen will perform or cause to be
      performed, in conformity with the BCH Companies security standards for
      physical security, the same or substantially the same physical security
      functions provided by the BCH Companies just prior to the Amendment
      Effective Date, including those physical security functions listed in
      Appendix 1, and such other security functions set out in this Exhibit K,
      at any facility where the Services are performed under this Agreement.
      Such procedures provide the necessary physical security to support

      23.4 of the Agreement, including through the implementation of industry
      standard security software and other equipment in order to afford maximum
      protection to the System and the BCH Company Data in a commercially

5.    INFORMATION SECURITY
5.1   Certen and the BCH Companies will perform the following functions in
      carrying out their respective responsibilities, the whole as applied by
      the BCH Companies just prior to the Amendment Effective Date and in
      conformity with the BCH Companies' security standards for logical security
      and under the direction of the BCH Companies' coordination function:
      (a)   Ensure that all users of the processing environment have authorized
            access. Monitor, review and respond to any violation and/or
            suspected violation; report such violations and/or suspected
            violations to ▇▇▇▇ or to Certen, as the case may be. Review the
            severity of any violations with appropriate management. Determine
            and implement activities to deter subsequent violations.
      (b)   Capture data for audit trail purposes of all access exceptions, and
            make data available to the BCH Companies, or to Certen, as the case
            may be, as part of the periodic status report.
      (c)   Provide ongoing operational support of system security processes to
            supported environments.
      (d)   Initiate corrective actions to ensure violation will not occur
            again. Each party shall prepare and retain documentation of
            violation investigations and provide copies to ▇▇▇▇ or to Certen, as
            the case may be.
      (e)   Recover from impact of security violations that result in
            lost/damaged information, when technically possible and commercially
            reasonable.
      (f)   Certen, in consultation with ▇▇▇▇, will identify security risks, and
            recommend procedures to minimize them. When approved by ▇▇▇▇, Certen
            will implement such procedures at ▇▇▇▇'▇ cost and expense.
6.    VIRUS PROTECTION
6.1   For the workstation and server environments, which Certen supports, and
      for all other Software, which it uses in delivering the Services, Certen
      will:
      (a)   install and maintain virus control tools;
      (b)   update virus Software and virus definition files so as to remain
            current with the selected supplier of virus Software; and
      (c)   recover virus corrupted files as required and commercially
            reasonable.
                                     - 8 -
6.2   ▇▇▇▇ will take reasonable steps to ensure that data (whether BCH Company
      Data or otherwise) entered onto the Systems which are under its
      responsibility will be free of viruses.

AND
_____________________________, a corporation organized and existing under the

WHEREAS CERTEN (or any of its affiliated companies) is the owner and/or the
author of and/or has the right to license certain valuable proprietary routines,
computer programs, documentation, trade secrets, systems, methodology, know-how,
marketing and other commercial knowledge, techniques, specifications, plans and
other proprietary information, all of which, including any related ideas and
look-and-feel, are referred to in this Agreement as the "CERTEN PROPRIETARY

For the purposes of this Agreement, CERTEN Proprietary Information shall
include, without limitation, (i) any technical, financial or business
information, data, idea, concept or know-how that is considered and treated as
being confidential by CERTEN; (ii) the fact discussions between the parties
hereto have been or are taking place; (iii) the fact that confidential
information will be disclosed to the Receiving Party; and (iv) the existence or
terms and conditions of this Agreement. CERTEN Proprietary Information disclosed

the obligation to treat as confidential information which would be considered
confidential by a person exercising reasonable business judgment; and
WHEREAS CERTEN has been engaged by ▇▇▇▇ Canada to provide _______________ [name

WHEREAS CERTEN agrees to provide Receiving Party with the requested access to
the specific CERTEN Proprietary Information required for Receiving Party to

      avoidance of doubt, such employees shall have access to only the specific
      CERTEN Proprietary Information required for provision of the Consulting
      Services. In the event that Receiving Party would like to disclose the
      CERTEN Proprietary Information to any other party, such other party must

      made in writing, in any tangible form, electronically or orally, by

      disclosure of the CERTEN Proprietary Information to Receiving Party will

      (b)   is lawfully and on a non-confidential basis obtained by Receiving

            keep it confidential;
      (c)   by documentary and competent evidence was previously known to
            Receiving Party without an obligation to keep it confidential;
      (d)   is expressly released in writing from such obligations by CERTEN; or
      (e)   is required to be disclosed pursuant to law, regulation, judicial or
            administrative order or request by a governmental or other entity

            Receiving Party first notifies CERTEN to enable it to seek relief
            from such requirement, and renders reasonable assistance requested
            by CERTEN (at CERTEN's expense) in connection therewith.
8.    This Agreement shall be in full force and effect for a period commencing
      on the date first stated above and ending either four (4) years after the
      conclusion of the Consulting Services referred to herein or seven (7)
      years from the date first stated above, whichever occurs later. However,
      the provisions of Sections 2 and 5 shall survive the termination or
      expiration of this Agreement for any reason.
9.    In the event that Receiving Party discloses, disseminates, releases or
      uses any part of CERTEN Proprietary Information, except as provided for in
      this Agreement, such disclosure, dissemination, release or use, or the
      threat thereof, shall be deemed to be a material breach of this Agreement.
      In the event of any material breach of this Agreement by Receiving Party
      (including but not limited to the foregoing), Receiving Party, upon demand
      from CERTEN, shall immediately discontinue access to the CERTEN
      Proprietary Information and immediately return to CERTEN all CERTEN
      Proprietary Information, including any copies thereof. In the event that a
      copy of any part of the CERTEN Proprietary Information cannot be returned
      as a result of physical impossibility, such copy shall be promptly
      destroyed and such destruction shall be certified in writing by Receiving
      Party. The provisions of this paragraph are in addition to any other legal
      or equitable rights and remedies that CERTEN may have.
10.   Receiving Party acknowledges that a breach of this Agreement may cause
      CERTEN extensive and irreparable harm and damage, and agrees that CERTEN
      shall be entitled to specific performance and injunctive relief or other
      equitable to prevent use or disclosure of the CERTEN Proprietary
      Information not authorized by this Agreement, in addition to any other
      remedy available to CERTEN under applicable law.
11.   Furthermore, Receiving Party hereby acknowledges that any breach of this
      Agreement may result in the termination of its agreement to provide the
      Consulting Services to the BCH Company as a result of CERTEN's activities
      to protect its rights under this Agreement, and agrees that it shall have
      no
                                      -5-
      recourse or cause of action against CERTEN and/or the BCH Company based
      upon or in connection with such activities.
12.   This Agreement constitutes the entire Agreement between the parties and
      supersedes any prior or contemporaneous oral or written representation
      with regard to the subject matter hereof. This Agreement may not be
      modified except by a written instrument signed by both parties.
13.   If, however, any provision of this Agreement is determined to be invalid
      or unenforceable, such invalidity or unenforceability shall not invalidate
      or render unenforceable the entire Agreement, but rather the entire
      Agreement shall be construed as if not containing the particular invalid
      or unenforceable provision, and the rights and obligations of the parties
      shall be construed and enforced accordingly. In addition, the parties
      hereby agree to cooperate with each other to replace the invalid or
      unenforceable provision with a valid and enforceable provision which will
      achieve the same result (to the maximum legal extent) as the provision
      determined to be invalid or unenforceable.
14.   The validity, performance, construction and effect of this Agreement shall
      be governed by the laws of the Province of 
Ontario (without regard to its
      rules on conflicts of laws) and the laws of Canada applicable therein.
15.   CERTEN does not make any representation or warranty as to the accuracy or
      completeness of CERTEN Proprietary Information. Receiving Party agrees
      that CERTEN will not have any liability to Receiving Party resulting from
      any use of CERTEN Proprietary Information by Receiving Party.
16.   This Agreement may not be assigned by Receiving Party, in whole or in
      part, without CERTEN's prior written consent. Assignment shall not relieve
      Receiving Party of its obligations hereunder.
17.   A term or condition of this Agreement can be waived or modified only by
      written consent of both parties. No failure or delay in exercising any
      right, power or privilege hereunder shall operate as a waiver thereof, nor
      shall any single or partial exercise thereof preclude any other or further
      exercise thereof or the exercise of any right, power or privilege
      hereunder.
18.   No single or partial exercise of any right or remedy under this Agreement
      shall preclude any other or further exercise of any other right or remedy
      in this Agreement or as provided at law or in equity. Rights and remedies
      provided in this Agreement are cumulative and not exclusive of any right
      or remedy provided at law or in equity.
19.   This Agreement may only be amended by a written agreement duly executed by
      authorized representatives of the parties.
20.   Any notice, demand or other communication which under the terms of this
      Agreement or under any statute must or may be given or made by any party

      (c)   by documentary and competent evidence was previously known to
            Receiving Party without an obligation to keep it confidential;
      (d)   is expressly released in writing from such obligations by CERTEN; or
      (e)   is required to be disclosed pursuant to law, regulation, judicial or
            administrative order or request by a governmental or other entity
            authorized by law to make such request; provided, however, that
            Receiving Party first notifies CERTEN to enable it to seek relief
            from such requirement, and renders reasonable assistance requested
            by CERTEN (at CERTEN's expense) in connection therewith.
9.    This Agreement shall be in full force and effect for a period commencing
      on the date first stated above and ending either four (4) years after the
      conclusion of the Consulting Services referred to herein or seven (7)
      years from the date first stated above, whichever occurs later. However,
      the provisions of Sections 2 and shall survive the termination or
      expiration of this Agreement for any reason.
10.   In the event that Receiving Party discloses, disseminates, releases or
      uses any part of CERTEN Proprietary Information, except as provided for in
      this Agreement, such disclosure, dissemination, release or use, or the
      threat thereof, shall be deemed to be a material breach of this Agreement.
      In the event of any material breach of this Agreement by Receiving Party
      (including but not limited to the foregoing), Receiving Party, upon demand
      from CERTEN, shall immediately discontinue access to the CERTEN
      Proprietary Information and immediately return to CERTEN all CERTEN
      Proprietary Information, including any copies thereof. In the event that a
      copy of any part of the CERTEN Proprietary Information cannot be returned
      as a result of physical impossibility, such copy shall be promptly
      destroyed and such destruction shall be certified in writing by Receiving
      Party. The provisions of this paragraph are in addition to any other legal
      or equitable rights and remedies that CERTEN may have.
11.   Receiving Party acknowledges that a breach of this Agreement may cause
      CERTEN extensive and irreparable harm and damage, and agrees that CERTEN
      shall be entitled to specific performance and injunctive relief or other
      equitable to prevent use or disclosure of the CERTEN Proprietary
                                      -5-

      remedy available to CERTEN under applicable law.

      Agreement may result in the termination of its agreement to provide the
      Consulting Services to the BCH Company as a result of CERTEN's activities
      to protect its rights under this Agreement, and agrees that it shall have
      no recourse or cause of action against CERTEN and/or the BCH Company based
      upon or in connection with such activities.
13.   This Agreement constitutes the entire Agreement between the parties and
      supersedes any prior or contemporaneous oral or written representation
      with regard to the subject matter hereof. This Agreement may not be
      modified except by a written instrument signed by both parties.
14.   If, however, any provision of this Agreement is determined to be invalid
      or unenforceable, such invalidity or unenforceability shall not invalidate
      or render unenforceable the entire Agreement, but rather the entire
      Agreement shall be construed as if not containing the particular invalid
      or unenforceable provision, and the rights and obligations of the parties
      shall be construed and enforced accordingly. In addition, the parties
      hereby agree to cooperate with each other to replace the invalid or
      unenforceable provision with a valid and enforceable provision which will
      achieve the same result (to the maximum legal extent) as the provision
      determined to be invalid or unenforceable.
15.   The validity, performance, construction and effect of this Agreement shall
      be governed by the laws of the Province of 
Ontario (without regard to its
      rules on conflicts of laws) and the laws of Canada applicable therein.
16.   CERTEN does not make any representation or warranty as to the accuracy or
      completeness of CERTEN Proprietary Information. Receiving Party agrees
      that CERTEN will not have any liability to Receiving Party resulting from
      any use of CERTEN Proprietary Information by Receiving Party.
17.   This Agreement may not be assigned by Receiving Party, in whole or in
      part, without CERTEN's prior written consent. Assignment shall not relieve
      Receiving Party of its obligations hereunder.
18.   A term or condition of this Agreement can be waived or modified only by
      written consent of both parties. No failure or delay in exercising any
      right, power or privilege hereunder shall operate as a waiver thereof, nor
      shall any single or partial exercise thereof preclude any other or further
      exercise thereof or the exercise of any right, power or privilege
      hereunder.
19.   No single or partial exercise of any right or remedy under this Agreement
      shall preclude any other or further exercise of any other right or remedy
      in this Agreement or as provided at law or in equity. Rights and remedies
      provided in this Agreement are cumulative and not exclusive of any right
      or remedy provided at law or in equity.

being confidential by BELL or any or its affiliated companies; (ii) the fact

Receiving Party; and (iv) the existence or terms and conditions of this
Agreement. BELL Proprietary Information disclosed in tangible or electronic form
may be marked or otherwise identified by BELL or any of its affiliated companies

following services in connection with the Outsourcing Services provided by
CERTEN to BELL: ___________________________________ [To Be Added] (hereinafter

      for purposes of providing the Consulting Services. For avoidance of doubt,
      such employees shall have access to only the specific BELL Proprietary
      Information required for provision of the Consulting Services. In the
      event that Receiving Party would like to disclose the BELL Proprietary
      Information to any other party, such other party must first sign a written
      agreement with CERTEN AND BELL binding such other party to terms and
      conditions substantially similar to those of this Agreement.
2.    Furthermore, Receiving Party hereby undertakes:
      (a)   not to use the BELL Proprietary Information for any purposes other
            than as may be necessary in order to perform the Consulting
            Services; furthermore, Receiving Party undertakes not to use outside

      and/or upon the conclusion of the Consulting Services and/or at the
      request of BELL, Receiving Party shall:

      company. Furthermore, disclosure of the BELL Proprietary Information to
      Receiving Party will only entitle Receiving Party to use such information
      for purposes of providing the Consulting Services as provided hereunder.
6.    Any use by Receiving Party of the BELL Proprietary Information permitted
      under this Agreement is conditioned upon Receiving Party first taking the
      safeguards and measures required to secure the confidentiality of such
      information. Without limiting the generality of the foregoing, Receiving
      Party shall draw to the attention of its employees, who shall have access
      to the BELL Proprietary Information, all the obligations contained in this
      Agreement.
7.    The confidentiality obligations of Receiving Party regarding the BELL
      Proprietary Information shall not apply to such information which
      Receiving Party can prove:
      (a)   becomes public domain without fault on the part of Receiving Party;

            Receiving Party first notifies BELL to enable it to seek relief from
            such requirement, and renders reasonable assistance requested by
            BELL in connection therewith.
8.    This Agreement shall be in full force and effect for a period commencing
      on the date first stated above and ending either four (4) years after the
      conclusion of the Consulting Services referred to herein or seven (7)
      years from the date first stated above, whichever occurs later. However,
      the provisions of Sections 2 and 5 shall survive the termination or
      expiration of this Agreement for any reason.
9.    In the event that Receiving Party discloses, disseminates, releases or
      uses any part of BELL Proprietary Information, except as provided for in
      this Agreement, such disclosure, dissemination, release or use, or the
      threat thereof, shall be deemed to be a material breach of this Agreement.
      In the event of any material breach of this Agreement by Receiving Party
      (including but not limited to the foregoing), Receiving Party, upon demand
      from BELL OR CERTEN, shall immediately discontinue access to the BELL
      Proprietary Information and immediately return to BELL all BELL
      Proprietary Information, including any copies thereof. In the event that a
      copy of any part of the BELL Proprietary Information cannot be returned as
      a result of physical impossibility, such copy shall be promptly destroyed
      and such destruction shall be certified in writing to BELL by Receiving
      Party. The provisions of this paragraph are in addition to any other legal
      or equitable rights and remedies that BELL may have.
10.   (a) Receiving Party acknowledges that a breach of this Agreement may cause
      BELL and/or CERTEN extensive and irreparable harm and damage, and agrees
      that BELL and/or CERTEN shall be entitled to specific performance and
      injunctive relief or other equitable relief to prevent use or disclosure
      of the BELL Proprietary Information not authorized by this Agreement, in
      addition to any other remedy available to BELL and/or CERTEN under
      applicable law.
      (b) Furthermore, Receiving Party hereby acknowledges that any breach of
      this Agreement may result in the termination of its agreement to provide
      the Consulting Services to CERTEN as a result of CERTEN's activities to
      protect its
                                      -5-
      rights under this Agreement, and agrees that it shall have no recourse or
      claim of action against BELL and/or CERTEN based upon or in connection
      with such activities.
11.   This Agreement constitutes the entire Agreement between the parties and
      supersedes any prior or contemporaneous oral or written representation
      with regard to the subject matter hereof. This Agreement may not be
      modified except by a written instrument signed by both parties.
12.   If, however, any provision of this Agreement is determined to be invalid
      or unenforceable, such invalidity or unenforceability shall not invalidate
      or render unenforceable the entire Agreement, but rather the entire
      Agreement shall be construed as if not containing the particular invalid
      or unenforceable provision, and the rights and obligations of the parties
      shall be construed and enforced accordingly. In addition, the parties
      hereby agree to cooperate with each other to replace the invalid or
      unenforceable provision with a valid and enforceable provision which will
      achieve the same result (to the maximum legal extent) as the provision
      determined to be invalid or unenforceable.
13.   The validity, performance, construction and effect of this Agreement shall
      be governed by the laws of the Province of 
Ontario (without regard to its
      rules on conflicts of laws) and the laws of Canada applicable therein.
14.   Neither BELL nor CERTEN makes any representation or warranty as to the
      accuracy or completeness of BELL Proprietary Information. Receiving Party
      agrees that neither BELL nor CERTEN will have any liability to Receiving
      Party resulting from any use of BELL Proprietary Information by Receiving
      Party.
15.   This Agreement may not be assigned by Receiving Party, in whole or in
      part, without BELL AND CERTEN's prior written consent. Assignment shall
      not relieve Receiving Party of its obligations hereunder.
16.   A term or condition of this Agreement can be waived or modified only by
      written consent of both parties. No failure or delay in exercising any
      right, power or privilege hereunder shall operate as a waiver thereof, nor
      shall any single or partial exercise thereof preclude any other or further
      exercise thereof or the exercise of any right, power or privilege
      hereunder.
17.   No single or partial exercise of any right or remedy under this Agreement
      shall preclude any other or further exercise of any other right or remedy
      in this Agreement or as provided at law or in equity. Rights and remedies
      provided in this Agreement are cumulative and not exclusive of any right
      or remedy provided at law or in equity.
18.   This Agreement may only be amended by a written agreement duly executed by
      authorized representatives of the parties.

      conditions substantially similar to those of this Agreement.
2.    Furthermore, Receiving Party hereby undertakes:
      (a)   not to use the BELL Proprietary Information for any purposes other

      right in, the BELL Proprietary Information or in any other proprietary
      product, trade ▇▇▇▇, copyright or other right of BELL or any affiliated
      company. Furthermore, disclosure of the BELL Proprietary Information to

      (c)   by documentary and competent evidence was previously known to

            administrative order or request by a governmental or other entity
            authorized by law to make such request; provided, however, that
            Receiving Party first notifies BELL to enable it to seek relief from
            such requirement, and renders reasonable assistance requested by
            BELL in connection therewith.
9.    This Agreement shall be in full force and effect for a period commencing
      on the date first stated above and ending either four (4) years after the
      conclusion of the Consulting Services referred to herein or seven (7)
      years from the date first stated above, whichever occurs later. However,
      the provisions of Sections 2 and 6 shall survive the termination or
      expiration of this Agreement for any reason.
10.   In the event that Receiving Party discloses, disseminates, releases or
      uses any part of BELL Proprietary Information, except as provided for in
      this Agreement, such disclosure, dissemination, release or use, or the
      threat thereof, shall be deemed to be a material breach of this Agreement.
      In the event of any material breach of this Agreement by Receiving Party
      (including but not limited to the foregoing), Receiving Party, upon demand
      from BELL OR CERTEN, shall immediately discontinue access to the BELL
      Proprietary Information and immediately return to BELL all BELL
      Proprietary Information, including any copies thereof. In the event that a
      copy of any part of the BELL Proprietary Information cannot be returned as
      a result of physical impossibility, such copy shall be promptly destroyed
      and such destruction shall be certified in writing to BELL by Receiving
      Party. The provisions of this paragraph are in addition to any other legal
      or equitable rights and remedies that BELL may have.
11.   (a) Receiving Party acknowledges that a breach of this Agreement may cause
      BELL and/or CERTEN extensive and irreparable harm and damage, and agrees
      that BELL and/or CERTEN shall be entitled to specific performance and
      injunctive relief or other equitable relief to prevent use or disclosure
      of the BELL Proprietary Information not authorized by this Agreement, in
      addition to any other remedy available to BELL and/or CERTEN under
      applicable law.
                                      -5-
      (b) Furthermore, Receiving Party hereby acknowledges that any breach of
      this Agreement may result in the termination of its agreement to provide
      the Consulting Services to CERTEN as a result of CERTEN's activities to
      protect its rights under this Agreement, and agrees that it shall have no
      recourse or claim of action against BELL and/or CERTEN based upon or in
      connection with such activities.
12.   This Agreement constitutes the entire Agreement between the parties and
      supersedes any prior or contemporaneous oral or written representation
      with regard to the subject matter hereof. This Agreement may not be
      modified except by a written instrument signed by both parties.
13.   If, however, any provision of this Agreement is determined to be invalid
      or unenforceable, such invalidity or unenforceability shall not invalidate
      or render unenforceable the entire Agreement, but rather the entire
      Agreement shall be construed as if not containing the particular invalid
      or unenforceable provision, and the rights and obligations of the parties
      shall be construed and enforced accordingly. In addition, the parties
      hereby agree to cooperate with each other to replace the invalid or
      unenforceable provision with a valid and enforceable provision which will
      achieve the same result (to the maximum legal extent) as the provision
      determined to be invalid or unenforceable.
14.   The validity, performance, construction and effect of this Agreement shall
      be governed by the laws of the Province of 
Ontario (without regard to its
      rules on conflicts of laws) and the laws of Canada applicable therein.
15.   Neither BELL nor CERTEN makes any representation or warranty as to the
      accuracy or completeness of BELL Proprietary Information. Receiving Party
      agrees that neither BELL nor CERTEN will have any liability to Receiving
      Party resulting from any use of BELL Proprietary Information by Receiving
      Party.
16.   This Agreement may not be assigned by Receiving Party, in whole or in
      part, without BELL AND CERTEN prior written consent. Assignment shall not
      relieve Receiving Party of its obligations hereunder.
17.   A term or condition of this Agreement can be waived or modified only by
      written consent of both parties. No failure or delay in exercising any
      right, power or privilege hereunder shall operate as a waiver thereof, nor
      shall any single or partial exercise thereof preclude any other or further
      exercise thereof or the exercise of any right, power or privilege
      hereunder.
18.   No single or partial exercise of any right or remedy under this Agreement
      shall preclude any other or further exercise of any other right or remedy
      in this Agreement or as provided at law or in equity. Rights and remedies
      provided in this Agreement are cumulative and not exclusive of any right
      or remedy provided at law or in equity.
                                      -6-
19.   This Agreement may only be amended by a written agreement duly executed by
      authorized representatives of the parties.

                  collective bargaining or other union agreement.

                  event [**] after the Time of Transfer, Certen shall initiate
                  the procedure for effecting the Transfer of the [**] to the

                  date hereof and the date of the actual transfer of the [**] if
                  such modifications would affect the Going Concern Pension
                  Liabilities or the Solvency Pension Liabilities, the benefits
                  of the Transferred Employees or the contributions with respect
                  to such benefits.

                  Transferred Employees under the Certen Pension Plan between
                  the Time of Transfer and the actual transfer of the [**] (the

                  during the Transitional Period, [**], as the case may be, [**]
                  (the "[**]").
                  As soon as practicable following the date on which the
                  applicable regulatory authority approves the transfer provided
                  under Section 4.5(e), Certen shall cause the funding agent of
                  the Certen Pension Plan to transfer to the pension fund of the
                  ▇▇▇▇ Pension Plan [**].
            (k)   Upon the completion of the Transfer contemplated above, the
                  Certen Pension Plan shall be completely discharged of all of
                  its obligations with respect to the defined benefit pension
                  benefits accrued by the Transferred Employees under the said
                  plan up to the Time of Transfer.

                  Employees will cease to participate in and receive benefits
                  from Certen's [**] (the "CERTEN BENEFIT PLANS") and, without

            (2)   [**] percent ([**]%) of the amount of any Claim which ▇▇▇▇ may
                  suffer or incur as a result of non-compliance by Certen with
                  such bulk sales legislation as may be applicable to the
                  transactions contemplated by this Agreement; and
            (3)   any non-compliance by Certen with Section 6 of the Retail

                  transactions contemplated by this Agreement. Notwithstanding

                  arising hereunder shall not exceed the amount obtained by

      5.3.  LIMITATIONS.
            Certen shall not shall indemnify and hold Bell, its directors,
            officers, employees, agents, representatives and ▇▇▇▇'▇ Affiliates
            and their respective directors, officers and employees harmless in
            respect of any Claim which may be made or brought against an
            Indemnified Party or which it may suffer or incur directly or
            indirectly as a result of, in respect of or arising out of:
            (1)   any incorrectness in or breach of any representation or
                  warranty of Certen contained in this Agreement or under any
                  other agreement, certificate or instrument executed and
                  delivered pursuant to this Agreement; or
            (2)   any incorrectness in the list of Affected Employees and
                  Independent Contractors attached hereto as Schedule 4.1(o).
      5.4.  NOTICE OF CLAIM.
            If an Indemnified Party becomes aware of a Claim in respect of which
            indemnification is provided for pursuant to either of Section 5.1 or
            5.2, as the case may be, the Indemnified Party shall promptly give
            written notice of the Claim to the Indemnifying Party. Such notice
            shall specify whether the Claim arises as a result of a claim by a
            Person against the Indemnified Party (a "THIRD PARTY CLAIM") or
            whether the Claim does not so arise (a "DIRECT CLAIM"), and shall
            also specify with reasonable particularity (to the extent that the
            information is available):
            (a)   the factual basis for the Claim; and
            (b)   the amount of the Claim, if known.
            If, through the fault of the Indemnified Party after having
            knowledge of the Claim, the Indemnifying Party does not receive
            notice of any Claim in time effectively to contest the determination
            of any liability susceptible of being contested, then the liability
            of the Indemnifying Party to the Indemnified Party under this
            Article shall be reduced by the amount of any losses incurred by the
            Indemnifying Party resulting from the Indemnified Party's failure to
            give such notice on a timely basis.
      5.5.  DIRECT CLAIMS.
            In the case of a Direct Claim, the Indemnifying Party shall have
            [**] from receipt of notice of the Claim within which to make such
            investigation of the Claim as the Indemnifying Party considers
            necessary or desirable. For the purpose of such investigation, the
            Indemnified Party shall make available to the Indemnifying Party the
            information relied upon by the Indemnified Party to substantiate the
            Claim, together with all such other information as the Indemnifying
            Party may reasonably request. If both parties agree at or before the
            expiration of such [**] period (or any mutually agreed upon
            extension thereof to the validity and amount of such Claim, the
            Indemnifying Party shall immediately pay to the Indemnified Party
            the full agreed upon amount of the Claim, failing which the matter
            shall be referred to binding arbitration in such manner as the
            parties may agree or shall be determined by a court of competent
            jurisdiction.
      5.6.  THIRD PARTY CLAIMS.
            In the case of a Third Party Claim, the Indemnifying Party shall
            have the right, at its expense, to participate in or assume control
            of the negotiation, settlement or defense of the Claim. If the
            Indemnifying Party elects to assume such control, the Indemnifying
            Party shall reimburse the Indemnified Party for all of the
            Indemnified Party's out-of-pocket expenses incurred as a result of
            such participation or assumption. The Indemnified Party shall have
            the right to participate in the negotiation, settlement or defense
            of such Third Party Claim and to retain counsel to act on its
            behalf, provided that the fees and disbursements of such counsel
            shall be paid by the Indemnified Party unless the Indemnifying Party
            consents to the retention of such counsel at its expense or unless
            the representation of both the Indemnifying Party and the
            Indemnified Party by the same counsel would be inappropriate due to
            the actual or potential differing interests between them (such as
            the availability of different defenses). The Indemnified Party shall
            cooperate with the Indemnifying Party so as to permit the
            Indemnifying Party to conduct such negotiation, settlement and
            defense and for this purpose shall preserve all relevant documents
            in relation to the Third Party Claim, allow the Indemnifying Party
            access on reasonable notice to inspect and take copies of all such
            documents and require its personnel to provide such statements as
            the Indemnifying Party may reasonably require and to attend and give
            evidence at any trial or hearing in respect of the Third Party
            Claim. If, having elected to assume control of the negotiation,
            settlement or defense of the Third Party Claim, the Indemnifying
            Party thereafter fails to conduct such negotiation, settlement or
            defense with reasonable diligence, then the Indemnified Party shall
            be entitled to assume such control and the Indemnifying Party shall
            be bound by the results obtained by the Indemnified Party with
            respect to such Third Party Claim.
      5.7.  SETTLEMENT OF THIRD PARTY CLAIMS.
            If the Indemnifying Party fails to assume control of the defense of
            any Third Party Claim, the Indemnified Party shall have the
            exclusive right to contest, settle or pay the amount claimed.
            Whether or not the Indemnifying Party assumes control of the
            negotiation, settlement or defense of any Third Party
            Claim, the Indemnifying Party shall not settle any Third Party Claim
            without the written consent of the Indemnified Party, which consent
            shall not be unreasonably withheld or delayed; provided, however,
            that the liability of the Indemnifying Party shall be limited to the
            proposed settlement amount if it is determined that the final
            settlement or judgment is less favorable taken as a whole than the
            proposed settlement taken as a whole and any such consent to such
            proposed settlement.
      5.8.  INTEREST ON CLAIMS.
            The amount of any Claim submitted under Section 5.1 or Section 5.2
            as damages or by way of indemnification shall bear interest from and
            including the date any Indemnified Party is required to make payment
            in respect thereof at the Prime Rate calculated from and including
            such date to but excluding the date reimbursement of such Claim by
            the Indemnifying Party is made, and the amount of such interest
            shall be deemed to be part of such Claim.
                                    ARTICLE 6
6.    GENERAL
      6.1.  PUBLIC NOTICES.

            concerning the matters contemplated by this Agreement shall be
            jointly planned and co-ordinated by the Parties and no Party shall
            act unilaterally in this regard without the prior approval of the
            other Parties, except where the Party making such notice is required
            to do so by law or by the applicable regulations or policies of any
            regulatory agency of competent jurisdiction or any stock exchange,
            provided that such party will use reasonable efforts to notify the
            other Party in advance of such disclosure so as to permit the other
            Parties to seek a protective order or otherwise contest such
            disclosure.
      6.2.  EXPENSES.
            Each Party to this Agreement shall pay its respective legal,
            accounting and other professional advisory fees, costs and expenses
            incurred in connection with the negotiation, preparation or
            execution of this Agreement and all documents and instruments
            executed or delivered pursuant to this Agreement.
      6.3.  FURTHER ASSURANCES.
            The Parties shall do all such things and actions and provide all
            such reasonable assurances as may be required to consummate the
            transactions contemplated by this Agreement, and each Party shall
            provide such further documents or instruments required by any other
            party as may be reasonably necessary or desirable to effect the
            purpose of this Agreement and carry out its provisions.
      6.4.  ASSIGNMENT AND ENUREMENT.
            Neither this Agreement nor any benefits or duties accruing under
            this Agreement shall be assignable by any Party without the prior
            written consent of the other Party; provided that each of the
            Parties may assign this Agreement after the Time of Transfer to one
            of its Affiliates without the prior written consent of the other
            Party, provided that the assigning Party shall remain liable for,
            and shall not be released from, its obligations under this Agreement
            and any documents delivered pursuant to this Agreement. Subject to
            the foregoing, this Agreement shall enure to the benefit of and be
            binding upon the Parties and their respective successors (including
            any successor by reason of amalgamation of any Party) and permitted
            assigns.
      6.5.  ENTIRE AGREEMENT
            This Agreement, together with any Schedules and Exhibits attached
            hereto and any documents delivered pursuant to this Agreement,
            constitutes the entire agreement between the Parties with respect to
            the matters herein and supersedes all prior agreements,
            understandings, negotiations, discussions representations, promises
            or statements, whether oral or written relating to the subject
            matter hereof. This Agreement shall not be amended, altered or
            qualified except by written agreement signed by all of the Parties.
      6.6.  WAIVER.
            Except as otherwise expressly set out herein, no waiver of any
            provision of this Agreement shall be binding unless it is in
            writing. No indulgence or forbearance by a Party shall constitute a
            waiver of such Party's right to insist on performance in full and in
            a timely manner of all covenants in this Agreement. Waiver of any
            provision shall not be deemed to waive the same provision
            thereafter, or any other provision of this Agreement at any time.
