Ladies and Gentlemen:

Fortis Inc., a corporation continued under the Corporations Act (Newfoundland and Labrador) (the “Corporation”), proposes to issue and sell to the several Underwriters named in Schedule I hereto (the “Underwriters”), an aggregate of 11,510,000 common shares of the Corporation (the “Firm Shares”).

The Corporation also proposes to issue and sell to the several Underwriters not more than an additional 1,726,500 common shares of the Corporation (the “Additional Shares”) if and to the extent that Scotia Capital Inc. (“Scotia Capital”) CIBC World Markets Inc. (“CIBC”) and RBC Dominion Securities Inc. (“RBC”), as the bookrunners (collectively, the “Bookrunners” or “you”) of the offering, shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares granted to the Underwriters in Section 3 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares”.

The Corporation is qualified under Canadian Securities Laws (as defined below), including the rules and procedures established pursuant to National Instrument 44-101 — Short Form Prospectus Distributions and National Instrument 44-102 — Shelf Distributions (the “Shelf Procedures”), in connection with a distribution of the Shares in each of the provinces of Canada (the “Canadian Qualifying Jurisdictions”) to file a prospectus in the form of a short form base shelf prospectus. A preliminary short form base shelf prospectus and a final short form base shelf prospectus, in each case, in respect of up to C$2,500,000,000 of common shares, first preference shares, second preference shares, subscriptions receipts, and debt securities of the Corporation (the “Shelf Securities”) have been filed with the Ontario Securities Commission (the “OSC”), as principal regulator, and with each of the securities commissions or similar regulatory authorities (the “Canadian Securities Commissions”) in each of the Canadian Qualifying Jurisdictions in respect of the offering of the Shelf Securities; a receipt (the “Preliminary Receipt”) has been obtained from the OSC in its capacity as principal regulator, representing the deemed receipt of each of the other Canadian Securities Commissions pursuant to Multilateral Instrument 11-102 — Passport System and National Policy 11-202 — Process for Prospectus Reviews in Multiple Jurisdictions (collectively, the “Passport System”) in respect of such preliminary short form base shelf prospectus; and a receipt (the “Final Receipt”) has been obtained from the OSC in its capacity as principal regulator, representing the deemed receipt of each of the other Canadian Securities Commissions pursuant to the Passport System in respect of such final short form base shelf prospectus in the form heretofore delivered to the Underwriters (together with all documents filed in connection therewith and all documents incorporated by reference therein). No

The preliminary prospectus supplement, dated November 25, 2019, relating to the offering of the Shares used in Canada which excludes the public offering price and other final terms, together with the Canadian Base Prospectus, is hereafter called the “Canadian Preliminary Prospectus”; the prospectus supplement relating to the offering of the Shares, which includes the public offering price and other final terms omitted from the Canadian Preliminary Prospectus, to be filed with the OSC as principal regulator and with each of the other Canadian Securities Commissions in accordance with the Shelf Procedures and in accordance with Section 8(b) hereof (the “Canadian Supplement”, together with the Canadian Base Prospectus, is hereinafter called the “Canadian Prospectus”). As used herein, the terms “Canadian Base Prospectus”, “Canadian Preliminary Prospectus”, “Canadian Supplement” and “Canadian Prospectus” shall in each case include the documents incorporated by reference therein.

The Corporation has filed with the Securities and Exchange Commission (the “Commission” or “SEC”) a registration statement on Form F-10 (File No. 333-228593), as amended, relating to the Shelf Securities and an appointment of agent for service of process on Form F-X (the “Form F-X”) relating to the registration statement; there are no reports or other information that in accordance with the requirements of the OSC or any Canadian Securities Commission must be made publicly available in connection with the offering of the Shares that have not been made publicly available as required; there are no documents required to be filed with the OSC or any Canadian Securities Commission in connection with the Prospectuses (as defined below) that have not been filed as required; there are no contracts, documents or other materials required to be described or referred to in the Registration Statement (as defined below) or the Prospectuses or to be filed or incorporated by reference as exhibits to the Registration Statement that are not described, referred to or filed or incorporated by reference as required. The registration statement as amended to the date of this Agreement is hereinafter called the “Registration Statement”; the base prospectus relating to the Shelf Securities filed as part of the Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement, is hereinafter called the “U.S. Base Prospectus”. For purposes of this Agreement, “U.S. Preliminary Prospectus” means the preliminary prospectus supplement, dated November 25, 2019, relating to the offering of the Shares, which excludes the public offering price and other final terms, together with the U.S. Base Prospectus, filed with the Commission pursuant to General Instruction II.L of Form F-10, and “U.S. Prospectus” means the final prospectus supplement relating to the offering of the Shares, which includes the public offering price and other final terms omitted from the U.S. Preliminary Prospectus, together with the U.S. Base Prospectus, to be filed with the Commission pursuant to General Instruction II.L of Form F-10 in accordance with Section 8(b) hereof. As used herein, the terms “Registration Statement”, “U.S. Base Prospectus”, “Time of Sale Prospectus”, “U.S. Preliminary Prospectus” and “U.S. Prospectus” shall in each case include the documents incorporated by reference therein.

For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the U.S. Securities Act of 1933, as amended (the “Securities Act”), “Time of Sale Prospectus” means the U.S. Preliminary Prospectus, together with the term sheet and other free writing prospectuses, if any, each identified in Schedule II hereto, in each case, exclusive of any amendment or supplement subsequent

As used herein, “Base Prospectuses” shall mean, collectively, the Canadian Base Prospectus and the U.S. Base Prospectus; “Preliminary Prospectuses” shall mean, collectively, the Canadian Preliminary Prospectus and the U.S. Preliminary Prospectus; and “Prospectuses” shall mean, collectively, the Canadian Prospectus and the U.S. Prospectus, as amended or supplemented, if applicable.

Concurrently with the execution of this Agreement, the Corporation entered into a subscription agreement (the “Subscription Agreement”) with an institutional investor providing for the sale by the Corporation to certain investment funds managed by the institutional investor (the “Purchasers”) of 9,587,728 common shares of the Corporation (the “Concurrent Offering Shares”) at a price of C$52.15 per common share, for total gross proceeds of C$500,000,015 (the “Concurrent Offering”). The completion of the offering of the Shares and the completion of the Concurrent Offering are not conditioned on each other.

Perry, Jocelyn H. Perry and James R. Reid, after due inquiry.

(b) it has all requisite corporate power and authority to enter into this Agreement and to carry out the transactions contemplated under this Agreement on the terms and conditions set forth herein.

The representations and warranties of each of the Underwriters contained in this Agreement shall be true as of the Closing Date as though they were made on the Closing Date and they shall survive the completion of the transactions contemplated under this Agreement until the completion of the distribution of the Shares.

3. Agreements to Sell and Purchase. The Corporation hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly (nor jointly and severally), to purchase from the Corporation at C$52.15 per Share (the “Purchase Price”) all (but not less than all) of the Firm Shares in the respective amounts set forth in Schedule I hereto opposite such Underwriter’s name.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Corporation grants an option to the Underwriters to acquire the Additional Shares accordance with this paragraph and agrees to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly (nor jointly and severally), up to 1,726,500 Additional Shares at the Purchase Price. Scotia Capital, CIBC and RBC may exercise this right on behalf of the Underwriters in whole or in part or from time to time by giving written notice not later than 30 days after the Closing Date. Any exercise notice shall specify the number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased. Each purchase date must be at least three business days after the written notice is given and may not be earlier than the Closing Date for the Firm Shares nor later than ten business days after the date of such notice. Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares and for market stabilization purposes. On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly (nor jointly and severally), to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Firm Shares set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

In consideration of the agreement on the part of the several Underwriters to purchase the Shares and to offer them to the public pursuant to the Prospectuses, the Underwriters shall be entitled to receive from the Corporation at the time of closing on the Closing Date or the Option Closing Date, as applicable, a fee equal to 4.0% of the gross proceeds to the Corporation from the Shares purchased on the Closing Date or the Option Closing Date, as applicable.

4. Terms of Public Offering. The Corporation is advised by you that the Underwriters commenced a public offering of their respective portions of the Shares. The Corporation is further advised

by you that the Shares have been offered to the public initially at C$52.15 per Share (the “Public Offering Price”). The Corporation acknowledges that the Underwriters may offer the Shares for sale to the public at a price less than the Public Offering Price after the Underwriters have made reasonable efforts to sell the Shares at the Public Offering Price.

5. Payment and Delivery. Payment for the Firm Shares to be sold by the Corporation shall be made to the Corporation in immediately available funds in Toronto against delivery of such Firm Shares for the respective accounts of the several Underwriters at or before 8:30 a.m., Toronto time, on December 3, 2019, or at such other time on the same or such other date, not later than December 24, 2019, as shall be agreed by the Corporation and you. The time and date of such payment are hereinafter referred to as the “Closing Date.”

The Firm Shares and Additional Shares shall be registered in such names and in such denominations as Scotia Capital, CIBC and RBC shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Shares and Additional Shares shall be delivered to Scotia Capital through the Delivery Mode, on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Shares to the Underwriters duly paid, against payment of the Purchase Price therefor.

9. Covenants of the Underwriters. (a) Each Underwriter severally covenants with the Corporation not to take any action that would result in the Corporation being required to file with the Commission under Rule 433(d) a free writing prospectus (other than the free writing prospectuses, if any, identified in Schedule III hereto, or any free writing prospectus prepared and filed in accordance with the terms of Section 8(o)) prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Corporation thereunder, but for the action of the Underwriter.

(b) The Underwriters hereby severally further covenant and agree with the Corporation the following: (i) during the period of distribution of the Shares by or through the Underwriters, the Underwriters will offer and sell the Shares to the public only in the Canadian Qualifying Jurisdictions and in the United States directly and through other duly registered investment dealers and brokers (the Underwriters, together with such other investment dealers and brokers, are referred to herein as the “Selling Firms”), upon the terms and conditions set forth in the Time of Sale Prospectus, the Prospectuses and in this Agreement; (ii) the Underwriters will use reasonable efforts to sell the Shares at the Purchase Price and if any such Shares remain unsold after such reasonable efforts, the Underwriters may sell such Shares at such price lower than the Purchase Price as is permitted under applicable law; and (iii) the Underwriters will notify the Corporation when, in the Underwriters’ opinion, the Underwriters have ceased the distribution of the Shares, and, as soon as reasonably practicable after completion of the distribution, will provide the Corporation, in writing, with a breakdown of the number of Shares distributed in each of the Canadian Qualifying Jurisdictions where that breakdown is required by a Canadian Securities Commission for the purpose of calculating fees payable to, or making filings with, that Canadian Securities Commission. The Underwriters will (and will cause the Selling Firms to) comply with Canadian Securities Laws and securities laws applicable to the Underwriters in the United States with respect to the offer to sell and the distribution of the Shares. Except in the Canadian Qualifying Jurisdictions and in the United States, the Underwriters will not, directly or indirectly, solicit offers to purchase or sell the Shares or deliver any Prospectuses so as to require the registration of the Shares or the filing of a prospectus with respect to the Shares under the laws of any jurisdiction.

10. Indemnity and Contribution. (a) The Corporation agrees to indemnify and hold harmless each Underwriter, and each of their respective officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of either section 15 of the Securities Act or section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses (other than loss of profits), claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by or based upon:

(i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Corporation information that the Corporation has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectuses or any amendment or supplement thereto, or any Marketing Materials, 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 in the light of the circumstances under which they were made, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Corporation in writing by such Underwriter through you expressly for use therein,

(ii) the Corporation not complying with any requirement of Canadian Securities Laws or the Securities Act and the applicable rules and regulations of the

Commission thereunder or stock exchange requirements in connection with this offering of the Shares, and

(iii) any breach by the Corporation of any representation or warranty contained in this Agreement.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party 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 party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (A) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters, and all of their respective officers, employees and agents, and all persons, if any, who control any Underwriter within the meaning of either section 15 of the Securities Act or section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (B) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Corporation, the officers of the Corporation who sign the Registration Statement and each person, if any, who controls the Corporation within the meaning of either such section. In the case of any such separate firm for the Underwriters and such officers, employees and agents, and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Scotia Capital, CIBC and RBC. In the case of any such separate firm for the Corporation, officers of the Corporation and control persons of the Corporation, such firm shall be designated in writing by the Corporation. The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested the indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party 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 60 days after receipt by the indemnifying party of the aforesaid request and (II) the indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. The indemnifying party shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 10(a) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Corporation, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 Corporation on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if

the allocation provided by clause 10(c)(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 10(c)(i) above but also the relative fault of the Corporation on the one hand and of the indemnified party or parties on the other hand 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 Corporation on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Corporation and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of each of the Prospectuses, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Corporation on the one hand and the Underwriters on the other hand 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 Corporation or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint (nor joint and several).

(d) The Corporation and the Underwriters agree that it would not be just or 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 Section 10(c). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(c) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 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 party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 10 and the representations, warranties and other statements of the Corporation contained 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, and any of their respective officers, employees or agents, any person controlling any Underwriter, or any affiliate of any Underwriter, or by or on behalf of the Corporation, its officers or directors or any person controlling the Corporation and (iii) acceptance of and payment for any of the Shares.

(f) The indemnifying party hereby acknowledges and agrees that, with respect to this Section 10, the Underwriters are contracting on their own behalf and as agents for their affiliates, directors, officers, employees and agents and their respective affiliates, directors, officers, employees and agents (collectively, the “Beneficiaries”). In this regard, each of the Underwriters will act as trustee for the Beneficiaries of the covenants of the indemnifying party under this Section 10 with respect to the Beneficiaries and accepts these trusts and will hold and enforce those covenants on behalf of the Beneficiaries.

11. Termination. The Underwriters may terminate this Agreement by notice given by you to the Corporation, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, either of the TSX

or the NYSE, (ii) a material disruption in securities settlement, payment or clearance services in Canada or the United States shall have occurred, (iii) any moratorium on commercial banking activities shall have been declared by Canadian or United States authorities, (iv) any inquiry, investigation or proceeding in relation to the Corporation or its directors or officers, whether formal or informal, is commenced, announced, or threatened, which, in the opinion of the Underwriters, acting in good faith, would reasonably be expected to have a material adverse effect on the Corporation and its subsidiaries (taken as a whole), (v) any law or regulation under or pursuant to any statute of Canada or of any province thereof, or of the United States or any state or territory thereof, is promulgated or changed which in the opinion of the Underwriters, acting in good faith, operates to prevent or materially restrict the distribution or trading of the Shares or which, in the opinion of the Underwriters, acting in good faith, would reasonably be expected to have a material adverse effect on the Corporation and its subsidiaries (taken as a whole), including as to the market price or value of the Shares, (vi) there is, in the opinion of the Underwriters, acting in good faith, a material change or a change in any material fact or a new material fact arises that would reasonably be expected to have a material adverse effect on the Corporation and its subsidiaries (taken as a whole), including as to the market price or value of the Shares, or (vii) there shall have occurred any outbreak or escalation of hostilities, terrorist action, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause, makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectuses.

12. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, the other Underwriters shall have the right to purchase, but not the obligation to purchase, in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and non-defaulting Underwriters have not elected to purchase such default Shares within 36 hours after such default, then each non-defaulting Underwriter shall have the several right to terminate its purchase obligation under this Agreement without any liability to it, and the Corporation shall have the right to proceed with the sale of the Shares (less the defaulted shares and any other terminations by the Underwriters) to the remaining Underwriters or to terminate this Agreement without liability on the part of any non-defaulting Underwriter or the Corporation. In any such case either you or the Corporation shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectuses or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Corporation to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Corporation shall be unable to perform its obligations under this Agreement, the Corporation will 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 disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. In all other instances, the Underwriters shall be solely responsible for their out-of-pocket expenses (including the fees and disbursements of their counsel) in connection with the transactions contemplated by this Agreement.

13. Entire Agreement. (a) This Agreement represents the entire agreement between the Corporation and the Underwriters with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectuses, the conduct of the offering, and the purchase and sale of the Shares. This Agreement supersedes that certain bid letter by and between Scotia Capital and the Corporation dated November 25, 2019.

14. Acknowledgment of the Corporation. The Corporation acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and have assumed no, and owe no, fiduciary or advisory duties to the Corporation or any other person, (ii) the Underwriters owe the Corporation only those duties and obligations set forth in this Agreement, and (iii) the Underwriters may have interests that differ from those of the Corporation. The Corporation waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

15. Action by the Underwriters. All steps which must or may be taken by the Underwriters in connection with this Agreement, with the exception of matters relating to termination, and the settlement of any indemnity claim may be taken by you on your behalf and on behalf of the other Underwriters, and the execution of this Agreement shall constitute the Corporation’s authority for accepting notification of any such steps or instructions by you.

16. TMX Group. Each of CIBC World Markets Inc., TD Securities Inc. and National Bank Financial Inc., or an affiliate thereof, owns or controls an equity interest in TMX Group Limited (“TMX Group”) and has a nominee director serving on the TMX Group’s board of directors. As such, each such investment dealer may be considered to have an economic interest in the listing of securities on any exchange owned or operated by TMX Group, including the TSX, the TSX Venture Exchange and the Alpha Exchange. No person or company is required to obtain products or services from TMX Group or its affiliates as a condition of any such dealer supplying or continuing to supply a product or service.

17. Counterparts. This Agreement may be signed in two or more counterparts (including by facsimile or pdf), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

18. Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

19. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

20. Notices.

21. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights 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.

FOR IMMEDIATE RELEASE

St. John’s, NL — November 25, 2019

FORTIS INC. ANNOUNCES C$1.1 BILLION OFFERING OF COMMON SHARES COMPRISED OF C$600 MILLION BOUGHT DEAL AND CONCURRENT C$500 MILLION OFFERING TO INSTITUTIONAL INVESTOR

Fortis Inc. (“Fortis” or the “Corporation”) (TSX/NYSE:FTS) announced today that it has entered into an agreement with a syndicate of underwriters led by Scotia Capital Inc., CIBC Capital Markets and RBC Capital Markets (collectively, the “Underwriters”), pursuant to which the Underwriters have agreed to purchase from Fortis, on a “bought deal” basis, and sell to the public, 11,510,000 common shares of Fortis (the “Common Shares”) at a price of C$52.15 per Common Share, resulting in gross proceeds for Fortis of C$600 million (the “Bought Deal”).

Fortis has granted the Underwriters the option to purchase up to an additional 1,726,500 Common Shares to cover over-allotments, if any, and for market stabilization purposes, exercisable during the 30 days following the closing of the Bought Deal (the “Over-Allotment Option”). If the Over-Allotment Option is exercised in full, the Bought Deal will result in gross proceeds for Fortis of C$690 million.

Fortis also announced today that it has entered into an agreement with an institutional investor in the United States that has agreed to purchase (the “Concurrent Offering” and together with the Bought Deal, the “Offerings”) 9,587,728 Common Shares at a price of C$52.15 per Common Share, resulting in gross proceeds for Fortis of C$500 million.

The Common Shares offered in the Concurrent Offering are being sold directly to the institutional investor without an underwriter or placement agent.

Fortis has provided notice to the agents under the equity distribution agreement dated December 10, 2018, relating to its at-the-market distribution (the “ATM Distribution”), that the Corporation is terminating its ATM Distribution as of today. The equity required by the Corporation to fund its ongoing capital plan is expected to be obtained through the Offerings and the Corporation’s dividend reinvestment program (“DRIP”) and, as a result, the ATM Distribution is no longer necessary.

The net proceeds of the Offerings will be used to fund the Corporation’s capital plan, repay indebtedness of Fortis and for general corporate purposes. “As we discussed on our recent quarterly call, our utility businesses are demonstrating strong growth, driven by investments to deliver cleaner energy and strengthen our energy networks. Furthermore, the recent FERC decision in respect of the return on equity for transmission removes a risk for our shareholders and allows Fortis to accelerate the funding outlined in our 5-year capital growth plan,” said Mr. Barry Perry, President and Chief Executive Officer of Fortis Inc.

Fortis also announced today that, subject to the approval of the TSX, it will be terminating the 2% discount currently offered on the purchase of Common Shares under its DRIP with effect for the March 1, 2020 dividend. As a result of the termination by Fortis of the discount under its DRIP, Fortis expects the rate of DRIP participation by the Corporation’s shareholders to decrease.

In respect of each Offering, a separate prospectus supplement (each, a “Prospectus Supplement”) to the Corporation’s Canadian base shelf prospectus (the “Base Prospectus”) dated December 6, 2018 will be filed in Canada with applicable securities regulatory authorities, as well as in the United States with the Securities and Exchange Commission (the “SEC”) under the Corporation’s U.S. registration statement on Form F-10 filed on November 29, 2018, amended on December 7, 2018, and which became effective on December 7, 2018. Each Prospectus Supplement will be available on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

Completion of each of the Offerings is subject to customary conditions and the receipt of all necessary stock exchange approvals, including the approvals of the TSX and the NYSE. Closing is expected to occur on or about December 3, 2019.

This media release does not constitute an offer to sell or the solicitation of an offer to buy the Common Shares, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Fortis Inc. has filed a registration statement (including a prospectus) with the SEC for the Bought Deal. Before you invest, you should read the prospectus supplement relating to the Bought Deal, the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and the Bought Deal. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the Bought Deal will arrange to send you the prospectus or you may request it in Canada from Scotia Capital Inc., Attention: Equity Capital Markets, Scotia Plaza, 64th Floor, 40 King Street West, Toronto, Ontario M5H 3Y2, or by telephone at 1-416-863-7704 or by email at equityprospectus@scotiabank.com and in the United States from Scotia Capital (USA) Inc., Attention: Equity Capital Markets, 250 Vesey Street, 24th Floor, New York, New York, 10281, or by telephone at 1-212-225-6853 or by email at equityprospectus@scotiabank.com.

13. Each of the Canadian Base Prospectus and the Canadian Prospectus Supplement (including, in each case, the documents incorporated by reference therein, but excluding, in each case, the financial statements and other financial or statistical data contained or incorporated by reference therein or omitted therefrom), appears on its face, as of the date of the filing thereof, to have been appropriately responsive in all material respects to the form requirements of Ontario Securities Laws (being the Securities Act (Ontario), together with the regulations and rules thereunder and all local instruments of the Ontario Securities Commission (the “OSC”) and the national or multilateral instruments of the Canadian Securities Administrators that are applicable in the Province of Ontario), including the Canadian Shelf Procedures, as interpreted and applied by the OSC.

14. All necessary documents have been filed, all necessary proceedings have been taken and all necessary approvals, permits, consents and authorizations of the Canadian Qualifying Authorities have been obtained, in each case by the Corporation under Canadian Securities Laws, to qualify the distribution of the Shares to the public in each of the Canadian Qualifying Jurisdictions by or through persons or companies who are registered in an appropriate category of registration under applicable Canadian Securities Laws and have complied with the relevant provisions of such Canadian Securities Laws and the terms and conditions of their registration.

15. The statements set out in the Canadian Prospectus under the headings “Enforceability of Certain Civil Liabilities”, to the extent that they constitute matters of law or legal conclusions, have been reviewed by us and fairly present the information disclosed therein in all material respects, subject to the limitations, qualifications, assumptions and exceptions stated or referred to therein.

16. The statements set out in the Canadian Prospectus Supplement under the heading “Certain Canadian Federal Income Tax Considerations” and under the heading “Eligibility for Investment” fairly summarize, in all material respects, the matters described therein, subject to the limitations, qualifications, assumptions and exceptions stated or referred to therein.

17. No withholding tax imposed under the federal laws of Canada will be payable in respect of the payment or crediting of any commission or fee as contemplated by this Agreement to an Underwriter that is not resident in Canada, but resident in the United States, for purposes of the Income Tax Act (Canada) and the Canada-United States Income Tax Convention (1980) (a “Qualifying U.S. Underwriter”), provided that any such commission or fee is payable in respect of services rendered by such Qualifying U.S. Underwriter wholly outside of Canada.

In giving the opinions described above, such counsel may (A) exclude from such opinions the effect or applicability of any law, rule or regulation that is applicable to the Corporation, solely because the law,

MATTERS TO BE COVERED BY

INITIAL OPINION OF CORPORATION’S U.S. COUNSEL

1. Assuming the compliance of the Canadian Prospectus, including the documents incorporated by reference therein, with the requirements of the securities laws and regulations of the Province of Ontario and other requirements of Canadian law, the Registration Statement and the U.S. Prospectus (other than the financial statements, including schedules, and other financial and statistical information contained therein or omitted therefrom, as to which such counsel need express no opinion) appear on their face to be appropriately responsive as to form in all material respects with the applicable requirements of the Securities Act and the rules and regulations thereunder; the Form F-X, as of its date, appears on its face to be appropriately responsive in all material respects to the requirements of the Securities Act.

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 (other than as required by any state securities laws, as to which such counsel expresses no opinion) is required on the part of the Corporation under any Applicable Law for the issuance or sale of the Shares or the performance by the Corporation of its obligations under this Agreement, except that such counsel need not express any opinion with respect to any filing with the SEC that may be required to be made by the Corporation under federal securities laws after the date the opinion is rendered. For purposes of the opinion, 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. For purposes of the opinion, the term “Applicable Law” means those laws, rules and regulations of the United States of America and the State of New York, in each case which in our experience are normally applicable to the transactions of the type contemplated by this Agreement; provided that Applicable Laws shall not include federal securities laws (except for purposes of the opinions expressed in paragraphs 1 above, this paragraph 2 and paragraph 4 below, but only to the extent and subject to the limitations set forth therein), state securities or blue sky laws, and any anti-fraud laws.

3. Assuming that this Agreement has been duly authorized by the Corporation, this Agreement (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Corporation.

4. The Corporation is not, and after giving effect to the offer and sale of the Shares and the Concurrent Offering Shares and the application of the proceeds thereof as described in the U.S. Prospectus 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 SEC promulgated thereunder.

5. The statements in the Time of Sale Prospectus and the U.S. Prospectus under the heading “Certain United States Federal Income Tax Considerations” with respect to the tax considerations under United States federal income tax law, to the extent that they constitute summaries of United States federal statutes, rules and regulations, or portions thereof, have been reviewed by us and fairly summarize the matters described under this heading in all material respects.

6. Neither the execution and delivery of this Agreement, nor the issue and sale of the Shares, nor the consummation of any other of the transactions herein contemplated nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of or imposition of any lien, charge or encumbrance upon any property or assets of the Corporation pursuant to (i) the terms of such material agreements as are set out in Schedule A hereto (except with respect to any provision

Schedule V-1

thereof to the extent that an opinion with respect to such provision would require making any financial, accounting or mathematical calculation or determination) or (ii) any United States federal or New York State statute, law, rule, or regulation known to such counsel to be applicable to the Offering, other than any federal or state securities laws (as to which such counsel expresses no opinion) and excluding the Corporation’s and any subsidiary’s specially regulated activities (as to which such counsel need express no opinion) or, to the knowledge of such counsel, any judgment, order or decree applicable to the Corporation of any United States federal or New York State court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Corporation or any of its properties in the United States, except, in the case of (i) or (ii), such conflicts, breaches, violations, liens, charges and encumbrances that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Corporation and its subsidiaries, taken as a whole.

Such counsel will state that to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened. For purposes of the opinion, the expression “knowledge” refers to the actual knowledge as of the date of the opinion of the attorneys of the New York office of such counsel (to be listed) who have rendered legal services to the Corporation in connection with the transactions contemplated by this Agreement.

In rendering such opinion, such counsel may (A) exclude from such opinions the effect or applicability of any law, rule or regulation that is applicable to the Corporation, solely because the law, rule or regulation is part of an industry specific regulatory regime applicable to the Corporation or any of its affiliates due to the specific assets or business of the Corporation or such affiliate, (B) rely as to matters involving the application of laws of any jurisdiction other than the State of New York or the Federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters and (C) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Corporation and public officials.

Such counsel will also state that they have reviewed the Registration Statement, the Time of Sale Prospectus and U.S. Prospectus and have participated in conferences with representatives of the Corporation, representatives of the independent chartered accountants for the Corporation, the Underwriters and representatives of the Underwriters at which the contents of the Registration Statement, the Time of Sale Prospectus and U.S. Prospectus and related matters were discussed. Given that many determinations involved in the preparation of the Registration Statement, the Time of Sale Prospectus and the U.S. Prospectus are of a wholly or partially non-legal character or relate to legal matters outside the scope of the letter, such counsel may state that they have not verified, and are not passing upon and do not assume responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in any of them, and have made no independent check or verification thereof. Subject to the foregoing and in the course of such participation (and relying as to factual matters to the extent such counsel deems reasonable on officers, employees and other representatives of the Corporation), no facts came to such counsel’s attention that gave them reason to believe that (a) the Registration Statement, at the time it became effective, 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, (b) the Time of Sale Prospectus, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading, or (c) the U.S. Prospectus, as of its date or as of the Closing Date (or the Option Closing Date, as applicable), included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. In each case, counsel need not express any belief as to

Schedule V-2
