The Company has prepared and filed with the British Columbia Securities Commission (the “Reviewing Authority”) and the Canadian securities regulatory authorities (together with the Reviewing Authority, the “Qualifying Authorities”) of each of the other provinces of Canada (including British Columbia, collectively, the “Qualifying Provinces”) in accordance with National Instruments 44-101 — Short Form Prospectus Distributions (“National Instrument 44-101”) and 44-102 - Shelf Distributions (“National Instrument 44-102”), a preliminary short form base shelf prospectus dated July 11, 2019 relating to debt securities, preferred shares, common shares, warrants to purchase equity securities, warrants to purchase debt securities, share purchase contracts, share purchase or equity units and subscription receipts (in the English and French languages, as applicable, the “Canadian Preliminary Prospectus”).

In consideration of the Underwriters’ agreement to purchase the Common Shares from the Company in accordance herewith, the Company agrees to pay the Underwriters a fee equal to 3.75% of the gross proceeds from the sale of the Firm Shares and the Option Shares by the Company to the Underwriters, if any (the “Underwriting Fee”).

2. The Over-Allotment Option is exercisable, in whole or in part, at any time until 30 days after the Closing Date at a price of C$52.00 per Option Share if the Over-Allotment Option is exercised and closed on or prior to March 13, 2020 (being the record date for the Share Split), or if the Over-Allotment Option is exercised or closed on or after March 17, 2020, at a price of C$26.00 per Option Share, for an aggregate purchase price of C$195,000,000 (assuming that the Over-Allotment Option is exercised in full). The Underwriters may exercise the Over-Allotment Option, in whole or in part, during the currency thereof by delivery of a written notice from the Representatives, on behalf of the Underwriters, to the Company, specifying the aggregate number of Option Shares which the Underwriters have agreed to purchase, subject to the terms of the Share Split, as applicable.

3. The Company understands that the Underwriters or their affiliates will offer the Offered Shares for sale to the public in the Qualifying Provinces and the United States.

The Underwriters agree to offer the Offered Shares only in accordance with, and in a manner permitted by, the laws of each jurisdiction in which such Offered Shares are permitted to be offered, as described under “Plan of Distribution” in the Canadian Supplement and the U.S. Supplement.

As used herein, the term “Business Day”

means any day other than a day on which banks are permitted or required to be closed in Toronto or New York. The time and date of such payment and delivery with respect to the Firm Shares are referred to herein as the “Closing Date”.

Payment for the Firm Shares shall be made against delivery to Underwriters of the Firm Shares to be purchased on the Closing Date in electronic or certificated form, in each case registered in the name of “CDS & Co.” or its nominee.

In all other respects, the applicable terms, conditions and provisions of this Underwriting Agreement shall apply mutatis mutandis to the Option Shares. If any Option Shares are purchased from the Company, each Underwriter agrees, severally and not jointly, to purchase such percentage of the aggregate number of Option Shares (subject to such adjustments to eliminate fractional shares as the Underwriters may determine) as is set out in Schedule II opposite the name of such Underwriter.

6. During the distribution of the Offered Shares, the Company and the Representatives, on behalf of the Underwriters, shall approve in writing (approval given by e-mail to be considered given in writing), prior to such time marketing materials (as such term is defined in National Instrument 41-101 — General Prospectus Requirements (“NI 41-101”)) are provided to potential investors resident in Canada, any marketing materials reasonably requested to be provided by the Underwriters to any potential investor of the Offered Shares, such marketing materials to comply with Canadian Securities Laws (as defined herein).

10. The Company agrees to indemnify and hold harmless each Underwriter, each affiliate of any Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the U.S. Securities Act or Section 20 of the Exchange Act, and each of their respective directors, officers, employees, agents, and affiliates from and against any and all losses (other than loss of profits), claims, damages and liabilities (including, without limitation, the legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Canadian Prospectus or the U.S. Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), any Issuer Free Writing Prospectus, any electronic road show, or the Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing through the Representatives.

In no event shall the indemnity provided in this Section 10 enure to the benefit of any person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the U.S. Securities Act) from any person who was not guilty of such fraudulent misrepresentation.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement, each person who controls the Company within the meaning of Section 15 of the U.S. Securities Act and Section 20 of the Exchange Act, and each of their respective officers, employees, agents and affiliates to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing through the Representatives expressly for use in the Registration Statement, the Canadian Prospectus and the U.S. Prospectus, any amendment or supplement thereto, any Issuer Free Writing Prospectus or Time of Sale Information.

If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to either of the first or third paragraphs of this Section 10, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding and all such fees and expenses shall be reimbursed as they are incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person, or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons. Any such separate firm for the Underwriters, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Offered Shares and such control persons of the Underwriters shall be designated in writing by the Representatives, and any such separate firm for the Company, its directors, its officers who sign or signed the Canadian Prospectus or the Registration Statement and such control persons of the Company or authorized representatives shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment

for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel for which the Indemnified Person is entitled to be reimbursed in accordance with this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request, and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (i) includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

If the indemnification provided for in the first and third paragraphs of this Section 10 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Offered Shares, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Offered Shares (before deducting expenses) received by the Company and the aggregate fee payable by the Company to the Underwriters bear to the aggregate public offering price of the Offered Shares. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, in no event shall an Underwriter be required to contribute any amount in excess of such aggregate fee or any portion of such fee actually received. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 10 are several in the percentages set forth opposite their names in Schedule II hereto, and not joint.

The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

The indemnity and contribution agreements contained in this Section 10 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any other person controlling the Company, and (iii) acceptance of and payment for any of the Offered Shares.

11. Notwithstanding anything herein contained, any Underwriter (each, a “Terminating Underwriter”) may, in its absolute discretion, terminate its obligations under this Agreement, by notice given to the Company and the Representatives (or, if the Terminating Underwriter is a Representative, to the Company and the other Representatives), if after the execution and delivery of this Agreement and prior to the Closing Date (i) (a) trading generally (or specifically in the case of the Common Shares) shall have been suspended or materially limited on or by, as the case may be, either of the NYSE or the TSX, (b) a material disruption in securities settlement, payment or clearance services in the United States or Canada shall have occurred, or (c) any moratorium on commercial banking activities shall have been declared by either Federal or New York State authorities or in Canada by the Canadian federal or provincial authorities, and in the case of any of the foregoing, such event, singly or together, in the opinion of the Underwriters or any of them, acting reasonably, would be expected to have a material adverse effect on the market price or market value of the Common Shares, (ii) any inquiry, action, suit, investigation or other proceeding (whether formal or informal) shall have been commenced, threatened or announced or any order or ruling shall have been issued under or pursuant to any statute of Canada or any province, or of the United States or any

state thereof or by any official of any stock exchange or by any other regulatory authority having jurisdiction over a material portion of the business, operations or affairs of the Company and its subsidiaries, taken as a whole, or otherwise, or there shall have been any change of law, or the interpretation, pronouncement or administration thereof or in respect thereof which in the opinion of such Underwriter, acting reasonably, prevents or operates to prevent or restrict the distribution of, trading in the Common Shares, (iii) there shall have occurred, developed or come into effect any event, action, state, condition, or major financial occurrence of national or international consequence or any law or regulation, any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the reasonable opinion of the Terminating Underwriter seriously adversely affects, or will seriously adversely affect (a) the financial markets in Canada or the United States, (b) the business, operations or affairs of the Company and its subsidiaries, taken as a whole, or (c) the market price or market value of the Common Shares, (iv) any material change or change in material fact in or affecting the general affairs, assets or properties, business, prospects, results of operations or the condition (financial or otherwise) of the Company and its subsidiaries, taken as a whole, that in any case in the opinion of the Underwriters or any of them, acting reasonably, would be expected to have a material adverse effect on the market price or market value of the Common Shares, or (v) the Company shall be in breach of or default under or in non-compliance with any material representation, warranty, term, condition or covenant of this Agreement in any material respect.

The rights of termination contained in this Section 11 may be exercised by any of the Underwriters and are in addition to any other rights or remedies any of the Underwriters may have in respect of any default, act or failure to act or non-compliance by the Company in respect of any of the matters contemplated by this Agreement or otherwise. In the event of any such termination, there shall be no further liability on the part of the Terminating Underwriter to the Company or on the part of the Company to the Terminating Underwriter except in respect of any liability which may have arisen prior to or arise after such termination under Sections 10 and 12 (and, for clarity, the Terminating Underwriter will not be entitled to any portion of the fee payable by the Company pursuant to Section 1). A notice of termination given by an Underwriter under this Section 11 shall not be binding upon any other Underwriter.

Upon the delivery of a notice of termination by a Representative under this Section 11, the Company may, in its absolute discretion, proceed with the sale of Offered Shares in accordance with the terms of this Agreement with the remaining Underwriters or terminate this Agreement.

12. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to reimburse the Underwriters or such

Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering of Offered Shares. The Underwriters or such Underwriters as have so terminated this Agreement will provide the Company with invoices in respect of any such out-of-pocket expenses to be reimbursed.

13. If one or more of the Underwriters shall fail at the Closing Date to purchase the aggregate number of Firm Shares which it or they are obligated to purchase under this Agreement or shall have exercised its right to terminate this Agreement as provided in Section 11 (the “Unpurchased Shares”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting and non-terminating Underwriters, or any other underwriters, to purchase all, but not less than all, of the Unpurchased Shares in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24 hour period, then: (a) if the aggregate number of Unpurchased Shares does not exceed 12% of the aggregate number of Firm Shares, each of the non-defaulting and non-terminating Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Unpurchased Shares in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting and non-terminating Underwriters; or (ii) if the number of Unpurchased Shares exceeds 12% of the aggregate number of Firm Shares, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section 13 shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, the Representatives shall have the right to postpone the Closing Date for a period not exceeding five Business Days in order to effect any required changes in the Registration Statement, the Time of Sale Information or Prospectuses or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 13.

14. This Agreement shall enure to the benefit of and be binding upon the Company, and each Underwriter, and to the extent provided for in Section 10, each person referred to in such section, and in each case, their respective successors, assigns, heirs and personal representatives. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

15. The Representatives are hereby authorized by each of the other Underwriters to act on its behalf and the Company shall be entitled to and shall act on any notice given in accordance with this Section 15 or agreement entered into by or on behalf of the Underwriters by the Representatives which represent and warrant that they have irrevocable authority to bind the Underwriters, except in respect of any consent to a settlement pursuant to Section 10, which consent shall be given by the Indemnified Person, or a notice of termination

pursuant to Section 11, which notice may be given by any of the Underwriters. The Representatives shall consult with the other Underwriters concerning any matter in respect of which they act as representative of the Underwriters. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

(b) In the event that any Underwriter that is a Covered Entity or a Covered Affiliate (as defined below) of any such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

ANNEX A-2

FORM OF NEGATIVE ASSURANCE LETTER OF

NORTON XXXX XXXXXXXXX CANADA LLP

We have participated in conferences with officers and other representatives of the Company, representatives of the Company’s auditors and of the Underwriters, representatives of the Company’s U.S. counsel and representatives of the Underwriters’ Canadian and U.S. counsel, at which the contents of the Registration Statement, the Time of Sale Information or the U.S. Prospectus and related matters were discussed. Although we did not participate in the preparation of the documents and information incorporated by reference in the U.S. Prospectus, we have reviewed such documents and information.

We have not made any independent investigation or verification of and are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in or incorporated by reference in the Registration Statement, the Time of Sale Information or the U.S. Prospectus (other than such conclusions of law as to which an opinion has been separately delivered to you). As the determination of materiality or whether a fact is a material fact under the Securities Act (Ontario) is a factual and not a legal matter requiring expertise on the effect which information would have on market prices or values of securities of the Company, we have accordingly relied as to materiality, to a large extent, on the opinions of officers and other representatives of the Company.

On the basis of the information which we gained in the course of the performance of our role as Canadian counsel to the Company in respect of the offering of the Offered Shares, no facts have come to our attention in the course of our review and discussions in connection with the offering of the Offered Shares that have caused us to believe that: (i) at the time it became effective, the Registration Statement; (ii) as of the Applicable Time, the Time of Sale Information; or (iii) at the time the U.S. Prospectus was issued, or at the Closing Date, the U.S. Prospectus (in each case excluding the financial statements and other financial and statistical information included or incorporated by reference therein or derived therefrom, the reports of management’s assessment of the effectiveness of internal controls over financial reporting and the auditors’ report on the effectiveness of the Company’s internal controls over financial reporting, on which we do not comment), contained or contains any untrue statement of a material fact within the meaning of the Securities Act (Ontario) or omitted or omits to state a material fact that is required to be stated or that is necessary to make a statement therein not misleading in the light of the circumstances in which it was made, within the meaning of the Securities Act (Ontario).

As used herein, (i) “Applicable Time” means 9:00 a.m. (Eastern Time) on February 20, 2020 and (ii) “Time of Sale Information” means the U.S. Final Prospectus, as supplemented by the U.S. Preliminary Supplement and the Term Sheet.

ANNEX B-1

FORM OF OPINION OF

XXXX, WEISS, RIFKIND, XXXXXXX & XXXXXXXX LLP

Ladies and Gentlemen:

We have acted as United States counsel to TELUS Corporation, a corporation organized under the laws of British Columbia (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated February 20, 2020, among you (the “Underwriters”) and the Company, relating to the purchase today by the Underwriters of 25,000,000 common shares (the “Shares”) of the Company. This opinion is being furnished at the request of the Company as contemplated by Section 9(h) of the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form F-10 (File No. 333-232601) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement was filed on July 11, 2019, was amended on July 19, 2019 and became effective upon filing on July 19, 2019 pursuant to Rule 467(a) under the Act. In this opinion, the Registration Statement at the time it became effective under the Act, including the documents incorporated by reference therein, is referred to as the “Registration Statement”; the base prospectus, dated July 19, 2019, included in the Registration Statement (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement, dated February 19, 2020, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, immediately prior to the Time of Sale is referred to as the “U.S. Pricing Prospectus”; the U.S. Pricing Prospectus, taken together with the documents set forth in Annex D to the Underwriting Agreement, dated February 20, 2020, is referred to as the “Pricing Disclosure Package”; and the Base Prospectus, as supplemented by the final prospectus supplement, dated February 20, 2020, as filed pursuant to General Instruction II.L. of Form F-10, including the documents incorporated by reference therein, is referred to as the “U.S. Prospectus.” Both the U.S. Pricing Prospectus and the U.S. Prospectus have been filed pursuant to General Instruction II.L. of Form F-10 in the manner and within the time period required by said General Instruction II.L. The Company has filed a short form base shelf prospectus (the “Canadian Base Prospectus”), dated July 19, 2019, a preliminary prospectus supplement (together with the Canadian Base Prospectus and the documents incorporated by reference therein, the “Canadian Pricing Prospectus”), dated February 19, 2020, and a final prospectus supplement (together with the Canadian Base Prospectus and the documents incorporated by reference therein, the “Canadian Prospectus”), dated February 20, 2020, in each case, with the British Columbia Securities Commission.

The Commission’s website indicates that no stop order suspending the effectiveness of the Registration Statement has been issued.

In connection with the furnishing of this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents:

1. the Registration Statement;

2. the U.S. Pricing Prospectus;

3. the U.S. Prospectus;

4. the Underwriting Agreement; and

5. the Form F-X of the Company, dated July 11, 2019 (as amended, the “Form F-X of the Company”).

In addition, we have examined such other certificates, agreements and documents as we deemed relevant and necessary as a basis for the opinions and beliefs expressed below. We have also relied upon oral and written statements of officers and representatives of the Company, the factual matters contained in the representations and warranties made in the Underwriting Agreement and upon certificates of public officials and officers of the Company. The documents incorporated by reference into the Registration Statement and the U.S. Prospectus were prepared by the Company without our participation.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete.

Based upon the above, and subject to the stated assumptions, exceptions and qualifications, we are of the opinion that:

1. The issuance and sale of the Shares by the Company, the execution and delivery by the Company of the Underwriting Agreement and the performance by the Company of its obligations thereunder will not violate those laws, rules and regulations of the United States of America and the State of New York (“Applicable Law”), in each case which in our experience are normally applicable to the transactions of the type contemplated by the Underwriting Agreement. For purposes of this letter, the term “Applicable Law” does not include federal securities laws (except for purposes of the opinion expressed in paragraph 2 below) or state securities laws, anti-fraud laws, or any law, rule or regulation that is applicable to the Company, the Underwriting Agreement or the transactions contemplated thereby solely because such law, rule or regulation is part of a regulatory regime applicable to any party to the Underwriting Agreement or any of its affiliates due to the specific assets or business of such party or such affiliate.

2. No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made, is required by the Company under any Applicable Law for the issuance and sale of the Shares by the Company, the execution and delivery by the Company of the Underwriting Agreement and the performance by the Company of its obligations thereunder. For purposes of this letter, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of the State of New York or the United States of America.

3. The Company is not and, after giving effect to the offering and sale of the Shares, and the application of their proceeds as described in the Pricing Disclosure Package and the U.S. Prospectus under the heading “Use of Proceeds,” will not be required to be, registered as an investment company under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

4. The statements in the Pricing Disclosure Package and the U.S. Prospectus under the heading “Certain United States Federal Income Tax Considerations,” to the extent that they constitute summaries of United States federal law or regulation or legal conclusions, have been reviewed by us and fairly summarize the matters described under that heading in all material respects.

5. The Registration Statement, the Form F-X of the Company and the U.S. Prospectus, as of their respective effective or issue times, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission under the Act, except for the financial statements, financial statement schedules and other financial data included or incorporated by reference in or omitted from any of them, and the Form T-1, as to which we express no opinion. We have assumed, for purposes of this paragraph, (i) the compliance of the Canadian Prospectus with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission and (ii) that the exhibits to the Registration Statement and the documents incorporated by reference in the U.S. Prospectus include all reports or information that in accordance with the requirements of British Columbia securities laws, as interpreted and applied by the British Columbia Securities Commission, must be made publicly available in connection with the offering of the Shares. We understand that such matters are covered in the opinion of Norton Xxxx Xxxxxxxxx Canada LLP furnished to you today.

The opinions expressed above are limited to the laws of the State of New York and the federal laws of the United States of America. Our opinions are rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect.

This letter is furnished by us solely for your benefit in connection with the transactions referred to in the Underwriting Agreement and may not be circulated to, or relied upon by, any other person without our prior written consent.

XXXX, WEISS, RIFKIND, XXXXXXX & XXXXXXXX LLP

Ladies and Gentlemen:

We have acted as United States counsel to TELUS Corporation, a corporation organized under the laws of British Columbia (the “Company”), in connection with the Underwriting Agreement (the “Underwriting Agreement”), dated February 20, 2020, among you (the “Underwriters”) and the Company, relating to the purchase today by the Underwriters of 25,000,000 common shares (the “Shares”) of the Company. This letter is being furnished at the request of the Company in connection with the delivery of our opinion to you of even date herewith (the “Opinion”) under the Underwriting Agreement. Capitalized terms used and not otherwise defined in this letter have the respective meanings given those terms in the Underwriting Agreement.

The primary purpose of our professional engagement was not to establish factual matters or financial, accounting or statistical information. In addition, many determinations involved in the preparation of the Registration Statement, the U.S. Pricing Prospectus and the U.S. Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of this letter. Furthermore, the limitations inherent in the independent verification of factual matters and in the role of outside counsel are such that we have not undertaken to independently verify, and cannot and do not assume responsibility for the accuracy, completeness or fairness of, the statements contained in the Registration Statement, the U.S. Pricing Prospectus or the U.S. Prospectus (other than as explicitly stated in paragraph 4 of the Opinion). The documents incorporated by reference into the Registration Statement and the U.S. Prospectus were prepared by the Company without our participation.

In the course of acting as United States counsel to the Company in connection with the offering of the Shares, we have participated in conferences and telephone conversations with officers and other representatives of the Company, its Canadian counsel, your representatives and your legal counsel and the independent registered public accountants for the Company during which conferences and conversations the contents of the Registration Statement, the Pricing Disclosure Package, the U.S. Prospectus and related matters were discussed. Based upon such participation (and relying as to factual matters on officers, employees and other representatives of the Company and its subsidiaries), our understanding of the U.S. federal securities laws and the experience we have gained in our practice thereunder, we hereby advise you that our work in connection with this matter did not disclose any information that caused us to believe that (i) at the time it became effective, the Registration Statement (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference and the Form T-1, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) as of the Time of Sale, the Pricing Disclosure Package (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) at the time the U.S. Prospectus was issued, or at the Closing Date, the U.S. Prospectus (except for the financial statements, financial statement schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom or from those documents incorporated by reference, as to which we express no such belief) included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.
