(3) Upon a Sale Notice being given by Baring, TELUS shall have the right to purchase all, but not less than all, of the Disposition Shares for cash at a price per Disposition Share equal to the Per Share Offering Price no later than the third Business Day following delivery of the Sale Notice. (4) To effect such a purchase, TELUS must, on or prior to the second Business Day following delivery of the Sale Notice (the “Notice Period”), give written notice to Baring (the “Acceptance Notice”), accepting the offer contained in the Sale Notice. If TELUS gives an Acceptance Notice within the Notice Period confirming its agreement to purchase, in aggregate, all of the Disposition Shares, TELUS and Baring shall consummate the sale of the Disposition Shares to TELUS, and TELUS shall pay to Baring the Aggregate Purchase Price in cash, no later than the seventh day following delivery of the Sale Notice. Any Disposition Shares sold to TELUS pursuant to this Section 5.1 shall be Multiple Voting Shares (to the extent permitted by applicable Law and the rules of any stock exchange on which the shares of the Company are listed) until Baring ceases to own any Multiple Voting Shares and, thereafter, any Disposition Shares sold to TELUS pursuant to this Section 5.1 shall be Subordinate Voting Shares. (5) If Baring does not receive an Acceptance Notice from TELUS within the Notice Period confirming TELUS’ agreement to purchase all of the Disposition Shares, or, if TELUS timely delivers an Acceptance Notice and fails to acquire the Disposition Shares and pay the Aggregate Purchase Price to Baring on or prior to the seventh day following delivery of the Sale Notice, TELUS’ right to purchase the Disposition Shares shall cease at the end of the Notice Period or at the end of the seventh day following the delivery of the Sale Notice, as applicable, and Baring, without limiting any remedies that may be available to Baring resulting from any failure of TELUS to timely acquire the Disposition Shares following TELUS’ delivery of an Acceptance Notice, may effect a Sale Transaction of the Disposition Shares to any person or entity, including the public, at any price, within six months after the expiry of the Notice Period. If the Disposition Shares are not sold within

- 14 - such six month period, the provisions of this Section 5.1 shall again apply to any proposed Sale Transaction, and so on from time to time. (6) This Section 5.1 shall apply for so long as the Baring Group owns, controls or directs, directly or indirectly, at least 10% of the Proportionate Voting Interest in the outstanding Shares (on a non-diluted basis). ARTICLE 6 CONFIDENTIALITY Section 6.1 Confidentiality Obligation. (1) Each Party will keep all Confidential Information (as defined below) confidential and will not disclose any Confidential Information to any Person or use any Confidential Information except as permitted by this Agreement. A Party may disclose Confidential Information to its employees and advisors but only to the extent that they need to know the Confidential Information, they have been informed of the confidential nature of the Confidential Information and they are directed to act in accordance with this Section 6.1; provided, that, such Party shall be liable for any breach by its employees or advisors of this Section 6.1. “Confidential Information” means all proprietary, confidential and other non-public information, know-how and data, regardless of the manner in which it is furnished (orally, in writing, electronically or otherwise), relating to or concerning the disclosing Party or their respective businesses, directors, officers or employees (including without limitation, agreements to which any of such Persons is a party, information and material concerning the disclosing Party’s past, present or future customers, suppliers, technology, business methods, systems, practices, strategies, financial conditions, assets, liabilities, operations, plans, potential financings or transactions or other activities) that is furnished to the other Parties pursuant to this Agreement and/or the Registration Rights Agreement on or after the date of this Agreement. (2) Notwithstanding the foregoing, (a) TELUS and Baring may display the Corporation’s name and/or corporate logo on their respective websites and in their respective marketing materials and may publicly disclose the existence of their investment in the Corporation (including in response to press or trade inquiries) and such other information required to be disclosed in order to comply with Applicable Securities Laws; (b) TELUS may disclose such Confidential Information as it deems reasonably relevant to TELUS Corporation for the purpose of its reporting obligations to TELUS Corporation; and (c) Baring may disclose such Confidential Information as it deems reasonably relevant to its direct or indirect shareholders and investors for the purpose of its reporting obligations to such Persons or in connection with the solicitation of prospective investors that may invest in Baring or one or more of its Affiliates, provided that any such Confidential Information shall be marked as confidential and the Persons to whom such Confidential Information is disclosed are informed of their confidentiality obligations with respect to such Confidential Information. Section 6.2 Confidentiality Exceptions. The restrictions set out in Section 6.1 (Confidentiality Obligation) do not apply to Confidential Information or any part of it that (a) is or becomes generally available to the public

- 15 - other than as a result of a disclosure by a Party (other than the Person that owns such Confidential Information) in violation of this Agreement, (b) was within a Party’s possession prior to its being furnished to it by or on behalf of the Person who owns such Confidential Information, (c) is or becomes available to such Party on a non-confidential basis from a source other than the Person who owns such Confidential Information (provided that the source of such information was not known by such Party to be bound by a confidentiality agreement with, or other contractual, legal or fiduciary obligations of confidentiality to, the Person who owns such Confidential Information), (d) is independently developed by such Party without violating any applicable obligations under this Agreement, (e) is required to be disclosed by Law (provided that if a Party becomes legally compelled or is required by a Governmental Entity having appropriate jurisdiction to disclose any of the Confidential Information, such Party shall (i) promptly provide the Corporation with written notice so that the Corporation may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Article 6, and (ii) cooperate with the Corporation to obtain a protective order or other remedy), or (f) is permitted in writing to be disclosed by the Person who owns such Confidential Information. Section 6.3 Ownership of Confidential Information. Nothing in this Agreement or in the disclosure of any Confidential Information will confer any interest in the Confidential Information on a receiving Party. The Parties share a common legal and commercial interest in all Confidential Information which is and remains subject to all applicable privileges, including solicitor-client privilege, anticipation of litigation privilege, work product privilege and privilege in respect of “without prejudice” communications. No waiver of any privilege is implied by the disclosure of Confidential Information to any Party pursuant to the terms of this Agreement. ARTICLE 7 DISPUTE RESOLUTION Section 7.1 Settling Disputes. (1) Upon being notified by a Party that there exists a dispute in connection with this Agreement (including its interpretation or application) (a “Dispute”), the Parties agree to meet or hold a telephone conference together within 10 days of such notification and to attempt to address and resolve the Dispute to the satisfaction of all of the Parties. The Parties agree to devote good faith efforts to resolve the Dispute which is the subject of the notification contemplated in this Article 7 (Dispute Resolution). (2) If a Dispute remains unresolved after 10 days following the giving of notice pursuant to Section 7.1(1), any Party may commence mediation upon giving written notice (the “Mediation Notice”) to the other Parties describing the Dispute to be resolved by mediation. Upon receipt of a Mediation Notice, the Parties will engage the services of a mediator to assist them in resolving the Dispute described in the Mediation Notice in accordance with the BC International Commercial Arbitration Centre’s (the “BCICAC”) rules of procedure that are in force at the time the Mediation Notice is served. In the event that the Parties cannot reach agreement on a mediator within five days from the receipt of the Mediation Notice, the Parties will ask the BCICAC to appoint a mediator. The mediation will be held in the City of Vancouver, British Columbia in English. At any mediation, the BCICAC’s rules of procedure will apply.

- 16 - (3) If a Dispute is not resolved by mediation as provided in Section 7.1(1) within 60 days of service of the Mediation Notice, any Party may terminate the mediation by providing written notice to the other Parties and, following delivery of such notice, any Party may commence legal proceedings in a court of competent jurisdiction in accordance with Section 8.12(2), provided that this Section 7.1(3) shall not constitute an admission by any Party that the subject matter of the unresolved Dispute is properly subject to resolution by legal proceedings in a court of competent jurisdiction. (4) Nothing herein will preclude any Party from seeking injunctive, provisional or protective relief in the courts of the Province of British Columbia or in the courts of another country in the event that the Party perceives that without such injunctive, provisional or protective relief, serious harm may be done to the Party. (5) Notwithstanding that a Dispute (or mediation or legal proceedings in respect of an unresolved Dispute) is ongoing, the Parties shall continue to perform all of their obligations under this Agreement, other than such obligations that are the subject matter of the Dispute, in order to ensure the uninterrupted and efficient conduct of the business of the Corporation.

A Party may change its address for service from time to time by providing a Notice in accordance with the foregoing. Any subsequent Notice must be sent to the Party at its changed address. Any element of a Party’s address that is not specifically changed in a Notice will be assumed not to be changed. Section 8.2 Time of the Essence. Time is of the essence in this Agreement in all respects. Section 8.3 Third Party Beneficiaries. The Parties intend that this Agreement will not benefit or create any right or cause of action in favour of any Person, other than the Parties. No Person, other than the Parties, is entitled to rely on the provisions of this Agreement in any action, suit, proceeding, hearing or other forum. The Parties reserve their right to vary or rescind the rights at any time and in any way whatsoever, if any, granted by or under this Agreement to any Person who is not a Party, without notice to or consent of that Person. Section 8.4 No Agency or Partnership. Nothing contained in this Agreement makes or constitutes any Party, or any of its directors, officers or employees, the trustee, fiduciary, representative, agent, principal, partner, joint venturer, of any other Party. It is understood that no Party has the capacity to make commitments of any kind or incur obligations or liabilities binding upon any other Party. Section 8.5 Expenses. Except as otherwise expressly provided in this Agreement, each Party will pay for its own costs and expenses incurred in connection with this Agreement and the transactions contemplated by it. The fees and expenses referred to in this Section are those which are incurred in connection with the negotiation, preparation, execution and performance of this Agreement, and the transactions contemplated by this Agreement, including the fees and expenses of legal counsel, investment advisers and accountants. Section 8.6 Amendments. This Agreement may only be amended, supplemented or otherwise modified by written agreement signed by an authorized signatory of the Party to be bound thereby.

- 19 - Section 8.7 Waiver. No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver of any provision of this Agreement or of any default, breach or non-compliance under this Agreement will be binding unless executed in writing by the Party to be bound by the waiver, and then only in the specific instance and for the specific purpose for which it has been given. A Party’s failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a Party from any other or further exercise of that right or the exercise of any other right. The waiver by a Party of any default, breach or non-compliance under this Agreement will not operate as a waiver of that Party’s rights under this Agreement in respect of any continuing or subsequent default, breach or non-observance (whether of the same or any other nature). Section 8.8 Entire Agreement. This Agreement and the Registration Rights Agreement together constitute the entire agreement between the Parties with respect to the matters contemplated by this Agreement and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties related to such matters. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the Parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement. The Parties have not relied and are not relying on any other information, discussion or understanding in entering into this Agreement. Section 8.9 Further Assurances. Each of the Parties agrees to execute and deliver such further and other documents, to cause such meetings to be held, resolutions to be passed and articles to be enacted, to exercise their votes, and to influence and perform, and/or cause to be performed, such further and other acts and things, as may be necessary or desirable in order to give full effect to this Agreement and every part hereof. Section 8.10 Successors and Assigns. (1) This Agreement becomes effective only when executed by all of the Parties. After that time, it is binding on and enures to the benefit of the Parties and their respective successors and permitted assigns, including any successor by way of amalgamation, merger, arrangement or other reorganization. (2) Except as otherwise provided in this Agreement, neither this Agreement nor any of the rights or obligations under this Agreement are assignable or transferable by any Party without the prior written consent of the other Parties. Section 8.11 Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable, by an arbitrator or any court of competent jurisdiction from which no appeal exists or is taken, that provision will be severed from this Agreement and the Parties shall substitute for the invalid

- 20 - provision a valid provision which most closely approximates the intent and economic effect of the invalid provision. Section 8.12 Governing Law. (1) This Agreement is governed by, and will be interpreted and construed in accordance with, the laws of the Province of British Columbia and the federal laws of Canada applicable therein. (2) Subject to Article 7 (Dispute Resolution), each Party irrevocably attorns and submits to the exclusive jurisdiction of the British Columbia courts situated in the City of Vancouver, and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum.
