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 Bell, and such fees shall be expressed for the [**] in terms of [**], and on [**] for the [**] as per the terms and conditions of the [**] Agreement. Bell acknowledges that its fees to [**] for the full calendar year 2002, for that portion of the [**] services to Bell 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 Bell 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.

Bell represents that its fees to [**] for the full calendar year 2002 for that portion of the [**] Services [**] fees to Bell which relate to the Services were [**] Canadian Dollars (CA$[**]) ("BELL'S [**] FEES"). Bell's [**] Fees projected for 2003 are [**] Canadian Dollars (CA$[**]). 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 Bell's [**] 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 Bell Mobility-[**] Services. Certen shall [**], as [**] under the [**] Agreements, to any right [**] granted by Bell or Bell 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 Bell 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.

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.

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.

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 Bell's 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 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. g.

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 Bell's 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.

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 Bell's 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.

However, if the market conditions will justify a larger increase (or a decrease), and only if agreed to by both Parties (with consent not to be unreasonably withheld), the increase (or decrease) of said rates, fees and charges may be larger (or smaller). In addition, the Parties agree that if any or all of the BCH Companies undergo a reorganization, such as a combination, split, or spinoff which does not affect the ultimate ownership of the BCH Companies or business units thereof, the Fees payable under this Section 10 shall be calculated following such reorganization in the same manner that the applicable Fees were calculated prior to such reorganization. 10.4 DISCOUNTS.

Certen grants to Bell a right of audit, through an independent firm of auditors, who shall enter into a non-disclosure agreement with Certen, to verify the appropriate application of the above-mentioned mechanism.

Each charge submitted on an invoice pursuant to this Agreement shall be paid by Bell (and broken down for each of the BCH Companies) within [**] of receipt.

The Late Factor shall be the equivalent of [**]% 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 Bell to Certen by the due date for that invoice. 12.4 TRANSFER TAXES. a. The recipient (whether Bell 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 Bell 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.

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 BELL TO PAY ANY ACCRUED BUT UNPAID AMOUNTS DUE AND OWING TO CERTEN PURSUANT TO THE TERMS OF THIS AGREEMENT, INCLUDING, BUT NOT LIMITED TO, THE TERMINATION CHARGES DESCRIBED IN SECTION 21.1 ABOVE; (II) LOSSES BY EITHER PARTY FOR BODILY INJURY OR DAMAGE TO REAL PROPERTY OR TANGIBLE PERSONAL PROPERTY; AND (III) EITHER PARTY'S OBLIGATIONS TO INDEMNIFY THE OTHER FOR INTELLECTUAL PROPERTY RIGHT INFRINGEMENT AND TAX LIABILITIES; AND (IV) BELL'S BREACH OF THE [**] PROVISIONS OF SECTION 6.1 (FOR WHICH BREACH OF SECTION 6.1, BELL'S LIABILITY WILL BE LIMITED TO AN AMOUNT EQUAL TO THE TERMINATION CHARGES DESCRIBED IN SECTION 21.1 ABOVE). 25.5 CERTEN'S LIABILITY FOR THE FAULTS OF ANY SUBCONTRACTORS OR THEIR SYSTEMS WHOSE CONTRACTS WITH THE BCH COMPANIES WERE EITHER ASSIGNED TO CERTEN OR 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 APPLICABLE FAULT OR BREACH. 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 Bell under this Agreement is critical to the overall operations and financial performance of Bell and that a substantial interruption of the performance of the Services would materially and adversely affect Bell. Accordingly, if a Force Majeure Event or a Guarantee Event results in the cessation of the Services (other than due to the fault of Bell or a third party), then Bell 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 Bell) 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 Bell 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 Bell), Certen will, for a five (5) day period allow Bell access to Certen's facilities as necessary for Bell 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, Bell may undertake to identify an alternate provider from which Certen may be able to procure such Services. If Bell identifies such an alternate source, Bell 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 Bell 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 Bell continues to pay Certen under Section 26.1(c)(iii)), alternatively, Bell may itself perform the Services. In such circumstances that a third party provider is engaged, Bell will first

62 afford Certen a reasonable opportunity to manage such provider performance, but if that is not accomplished, then Bell may itself manage such provider performance. Certen shall reasonably cooperate with such provider and/or Bell, 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 Bell 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. b. Bell 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 SECTION 28.

SECTION 30. AMENDMENT/CHANGES 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.

- 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. 3.7 MECHANISM FOR PENALTY REBATES OR BONUSES 3.7.1 ALLOCATION OF PERFORMANCE PENALTY REBATES A.

EXHIBIT C-2 MODERNIZED SYSTEM KVMS AND SLS ANNEXES Annex I - SL Agreement Template. The Parties shall work diligently and negotiate in good faith to settle the form of this Annex as soon as practicable following the Amendment Effective Date and in any event within 60 days of the Amendment Effective Date. I. INTRODUCTION The purpose of this Exhibit C-2 to the Agreement is to detail the methods, measurements and goals of service level monitoring for Services delivered by Certen to the BCH Companies relating to the Modernized System, and to that effect, to be consistent with the Services as they are outlined in Exhibit A. Should there be any gap between this Exhibit and Exhibit A, the Parties shall review such gap and amend this Exhibit C-2 accordingly. The terms of this Exhibit C-2 apply to the Modernized Systems and the terms of Exhibit C-1 apply to the Legacy Systems. The chart below outlines the Key Value Measures (hereinafter referred to in this Exhibit C-2 as "Critical Service Level KVMs" or "KVMs"), and Business/IT Operational Service Levels (hereinafter referred to as "SLs") referenced in this document (hereinafter collectively referred to as the "Performance Measures" (PMs) throughout this document). Capitalized terms in this Exhibit C-2, not otherwise defined herein, shall have the meanings set forth in the Agreement and in Exhibit C-1. ITEM MEASURE APPENDIX I KEY VALUE MEASURE (KVM) 1.

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 the related Suspended PM and Grace Periods: No. Suspension Grace Period Suspended KVM Suspended SL Event 1. [**] [**] [**] [**] 2. [**] [**] - [**] 3. [**] [**] - [**] [**] 4. [**] [**] [**] [**] 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 A. Bell 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. -5-

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 Bell 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 Bell will be excluded. Bell 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 Bell's 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 Bell. -17-

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. Bell 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 Bell 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 Bell 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 Bell 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. -19-

Special Time consumed and qualified as encumbered by Exclusions Certen waiting for any of the following from Bell: - Responses to inquiries - Additional required details relating to the Issue (e.g., specific billing account number (BAN) identifier) - Problem clarification shall be excluded from the calculation for this SL. Only Certen unencumbered time shall be included in the calculation of this SL. Defects that are found during a billing audit and measured against the Billing Delivery KVM will be excluded from the calculation. -20-

Disclosure of the CERTEN Proprietary Information to Receiving Party may be made in writing, in any tangible form, electronically or orally, by CERTEN. 5. Disclosure of the CERTEN Proprietary Information to Receiving Party shall in no way serve to create, on the part of Receiving Party, any proprietary right in, the CERTEN Proprietary Information or in any other proprietary product, trade mark, copyright or other right of CERTEN. Furthermore, disclosure of the CERTEN Proprietary Information to Receiving Party will only entitle Receiving Party to use such information for purposes of providing the Consulting Services. 6.

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.

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.

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.
