ABOUT THIS PROSPECTUS

This Prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process.

NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus, including the documents incorporated by reference into this Prospectus, contain both historical and forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”), and forward-looking information within the meaning of Canadian securities laws (collectively, “forward-looking statements”). This information has been included to provide readers with information about the Corporation and its subsidiaries and affiliates, including management’s assessment of the Corporation’s and its subsidiaries’ future plans and operations. This information may not be appropriate for other purposes. Forward-looking statements are typically identified by words such as “anticipate”, “expect”, “project”, “estimate”, “forecast”, “plan”, “intend”, “target”, “believe”, “likely” and similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or incorporated by reference in this Prospectus include, but are not limited to, statements with respect to the following: expected earnings before interest and income taxes (“EBIT”) or expected adjusted EBIT; expected earnings/(loss) or adjusted earnings/(loss); expected earnings/(loss) or adjusted earnings/(loss) per share; expected future cash flows; expected performance of the Liquids Pipelines business; financial strength and flexibility; expectations on sources of liquidity and sufficiency of financial resources; expected costs related to announced projects and projects under construction; expected in-service dates for announced projects and projects under construction; expected capital expenditures; expected equity funding requirements for the Corporation’s commercially secured growth program; expected future growth and expansion opportunities; expectations about the Corporation’s joint venture partners’ ability to complete and finance projects under construction; expected closing of acquisitions and dispositions; estimated future dividends; recovery of the costs of the Canadian portion of the Line 3 Replacement Program (the “Canadian L3R Program”); expected expansion of the T-South System and Spruce Ridge Program; expected capacity of the Hohe See Expansion Offshore Wind Project; expected costs in connection with Line 6A and Line 6B crude oil releases; expected effect of Aux Sable Consent Decree; expected future actions of regulators; expected costs related to leak remediation and potential insurance recoveries; expectations regarding commodity prices; supply forecasts; the expected use of proceeds and dividends; expectations regarding the impact of the Merger Transaction (as defined below) including the combined Corporation’s scale, financial flexibility, growth program, future business prospects and performance; impact of the Canadian L3R Program on existing integrity programs; dividend payout policy; dividend growth and dividend payout expectation; and expectations on impact of hedging program.

Although the Corporation believes these forward-looking statements are reasonable based on the information available on the date such statements are made and processes used to prepare the information, such statements are not guarantees of future performance and readers are cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from those expressed or implied by such statements. Material assumptions include assumptions about the following: the expected supply of and demand for crude oil, natural gas, natural gas liquids (“NGL”) and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange rates; inflation; interest rates; availability and price of labour and construction materials; operational reliability; customer and regulatory approvals; maintenance of support and regulatory approvals for the Corporation’s projects; anticipated in-service dates; weather; the realization of anticipated benefits and synergies of the Merger Transaction; governmental legislation; acquisitions and the timing thereof; the success of integration plans; impact of the dividend policy on the Corporation’s future cash flows; credit ratings; capital project funding; expected EBIT or expected adjusted EBIT; expected earnings/(loss) or adjusted earnings/(loss); expected earnings/(loss) or adjusted earnings/(loss) per share; expected future cash flows; and estimated future dividends. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these commodities, are material to and underlie all forward-looking statements, as they may impact current and future levels of demand for the Corporation’s services. Similarly, exchange rates, inflation and interest rates impact the economies and business environments in which the Corporation operates and may impact levels of demand for the Corporation’s services and cost of inputs, and are therefore inherent in all forward-looking statements. Due to the interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking statement cannot be determined with certainty, particularly with respect to the impact of the Merger Transaction on the Corporation, expected EBIT, adjusted EBIT, earnings/(loss), adjusted earnings/(loss) and associated per share amounts, or estimated future dividends. The most relevant assumptions associated with forward-looking statements on announced projects and projects under construction, including estimated completion dates and expected capital expenditures, include the following: the availability and

3

Table of Contents

price of labour and construction materials; the effects of inflation and foreign exchange rates on labour and material costs; the effects of interest rates on borrowing costs; the impact of weather; and customer, government and regulatory approvals on construction and in-service schedules and cost recovery regimes.

The Corporation’s forward-looking statements are subject to risks and uncertainties pertaining to the impact of the Merger Transaction, operating performance, regulatory parameters, dividend policy, project approval and support, renewals of rights of way, weather, economic and competitive conditions, public opinion, changes in tax laws and tax rates, changes in trade agreements, exchange rates, interest rates, commodity prices, political decisions and supply of and demand for commodities, including but not limited to those risks and uncertainties discussed in this Prospectus and in documents incorporated by reference into this Prospectus. The impact of any one risk, uncertainty or factor on a particular forward-looking statement is not determinable with certainty as these are interdependent and the Corporation’s future course of action depends on management’s assessment of all information available at the relevant time. Except to the extent required by applicable law, the Corporation assumes no obligation to publicly update or revise any forward-looking statements made in this Prospectus or otherwise, whether as a result of new information, future events or otherwise. All subsequent forward-looking statements, whether written or oral, attributable to the Corporation or persons acting on the Corporation’s behalf, are expressly qualified in their entirety by these cautionary statements.

The information incorporated by reference is considered to be a part of this Prospectus and should be read with the same care. When we update the information contained in documents that have been incorporated by reference by making future filings with the SEC the information incorporated by reference in this Prospectus is considered to be automatically updated and superseded. The modifying or superseding statement need not state that it has modified or superseded a prior statement or include any other information set forth in the document that it modifies or supersedes. In other words, in the case of a conflict or inconsistency between information contained in this Prospectus and information incorporated by reference into this Prospectus, you should rely on the information contained in the document that was filed later. The making of a modifying or superseding statement shall not be deemed an admission for any purposes that the modified or superseded statement, when made, constituted a misrepresentation, an untrue statement of a material fact or an omission to state a material fact that is required to be stated or that is necessary to make a statement not misleading in light of the circumstances in which it was made. Any statement so modified or superseded shall not be deemed, except as so modified or superseded to constitute a part of this Prospectus.

General

Material Canadian and United States federal income tax considerations applicable to any debt securities, and special tax considerations applicable to the debt securities denominated in a currency or currency unit other than Canadian or U.S. dollars, will be described in the Prospectus Supplement relating to the offering of debt securities.

Unless otherwise indicated in an applicable Prospectus Supplement, the debt securities will be unsecured obligations and will rank equally with all of the Corporation’s other unsecured and unsubordinated indebtedness. Enbridge is a holding company that conducts substantially all of its operations and holds substantially all of its assets through its subsidiaries. As at September 30, 2017, the long-term debt (excluding the current portion, as well as guarantees and intercompany obligations between the Corporation and its subsidiaries) of Enbridge and its subsidiaries totalled approximately $61.4 billion, of which approximately $40.2 billion is subsidiary debt. The debt securities issued under this Prospectus will be structurally subordinated to all existing and future liabilities, including trade payables and other indebtedness, of Enbridge’s subsidiaries.

The Indenture has been filed as an exhibit to the registration statement of which this Prospectus is a part and is available as described above under “Where You Can Find More Information”. The Indenture will be described in a Prospectus Supplement for such debt securities. For further details, prospective investors should refer to the Indenture and the applicable Prospectus Supplement.

Debt securities may also be issued under new supplemental indentures between us and a trustee or trustees as will be described in a Prospectus Supplement for such debt securities. The Corporation may issue debt securities and incur additional indebtedness other than through the offering of debt securities pursuant to this Prospectus.

The Prospectus Supplement will set forth additional terms relating to the debt securities being offered, including covenants, events of default, provisions for payments of additional amounts and redemption provisions.

The Prospectus Supplement will also set forth the following terms relating to the debt securities being offered:

· the title of the debt securities of the series;

· any limit upon the aggregate principal amount of the debt securities of the series;

· the period or periods if any within which, the price or prices at which, the currency or currency units in which and the terms and conditions upon which any debt securities of the series may be redeemed, in whole or in part, at the option of the Corporation;

· the obligation, if any, of the Corporation to redeem or purchase any debt securities of the series pursuant to any sinking fund or analogous provisions or at the option of the holder thereof and the terms and conditions upon which debt securities of the series may be redeemed or purchased, in whole or in part pursuant to such obligation;

· if other than denominations of $1,000 and any integral multiples of $1,000, the denominations in which the debt securities are issuable;

· if the amount of principal of or any premium or interest on any debt securities of the series may be determined with reference to an index or pursuant to a formula, the manner in which such amounts shall be determined;

· if other than U.S. dollars, the currency, currencies or currency units in which the principal of or any premium or interest on any debt securities of the series will be payable, and any related terms;

· if the principal of or any premium or interest on any debt securities of the series is to be payable, at the election of the Corporation or the holders, in one or more currencies or currency units other than that or those in which the debt securities are stated to be payable, specific information relating to the currency, currencies or currency units, and the terms and conditions relating to any such election;

· if other than the entire principal amount, the portion of the principal amount of any debt securities of the series that is payable upon acceleration of maturity;

· if the principal amount payable at maturity of the debt securities of the series is not determinable prior to maturity, the amount that is deemed to be the principal amount prior to maturity for purposes of the debt securities and the indenture;

· if applicable, that the debt securities of the series are subject to defeasance and/or covenant defeasance;

· if applicable, that the debt securities of the series will be issued in whole or in part in the form of one or more global securities and, if so, the depositary for the global securities, the form of any legend or legends which will be borne by such global securities and any additional terms related to the exchange, transfer and registration of securities issued in global form;

· any addition to or change in the events of default applicable to the debt securities of the series and any change in the right of the trustee or the holders of the debt securities to accelerate the maturity of the debt securities of the series;

Table of Contents

· if the debt securities are to be subordinated to other of the Corporation’s obligations, the terms of the subordination and any related provisions;

· whether the debt securities will be convertible into securities or other property, including the Corporation’s common stock or other securities, whether in addition to, or in lieu of, any payment of principal or other amount or otherwise, and whether at the option of the Corporation or otherwise, the terms and conditions relating to conversion of the debt securities, and any other provisions relating to the conversion of the debt securities;

· the obligation, if any, of the Corporation to pay to holders of any debt securities of the series amounts as may be necessary so that net payments on the debt security, after deduction or withholding for or on account of any present or future taxes and other governmental charges imposed by any taxing authority upon or as a result of payments on the securities, will not be less than the gross amount provided in the debt security, and the terms and conditions, if any, on which the Corporation may redeem the debt securities rather than pay such additional amounts;

· whether the Corporation will undertake to list the debt securities of the series on any securities exchange or automated interdealer quotation system; and

· any other terms of the series of debt securities.

Unless otherwise indicated in the applicable Prospectus Supplement, the Indenture does not afford the holders the right to tender debt securities to Enbridge for repurchase or provide for any increase in the rate or rates of interest at which the debt securities will bear interest in the event Enbridge should become involved in a highly leveraged transaction or in the event of a change in control of Enbridge.

Debt securities may be issued under the Indenture bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and may be offered and sold at a discount below their stated principal amount. The Canadian and United States federal income tax consequences and other special considerations applicable to any such discounted debt securities or other debt securities offered and sold at par which are treated as having been issued at a discount for Canadian and/or United States federal income tax purposes will be described in the applicable Prospectus Supplement.

Unless otherwise indicated in the applicable Prospectus Supplement, Enbridge may, without the consent of the holders thereof, reopen a previous issue of a series of debt securities and issue additional debt securities of such series.

DESCRIPTION OF SHARE CAPITAL

In this section, the terms “Corporation” and “Enbridge” refer only to Enbridge Inc. and not to its subsidiaries, partnerships or joint venture interests. The following sets forth the terms and provisions of the existing capital of the Corporation. The following description is subject to, and qualified by reference to, the terms and provisions of the Corporation’s articles and by-laws. The Corporation is authorized to issue an unlimited number of common shares and an unlimited number of preference shares, issuable in series.

Common Shares

Each common share of the Corporation entitles the holder to one vote for each common share held at all meetings of shareholders of the Corporation, except meetings at which only holders of another specified class or series of shares are entitled to vote, to receive dividends if, as and when declared by the board of directors of the Corporation, subject to prior satisfaction of preferential dividends applicable to any preference shares, and to participate rateably in any distribution of the assets of the Corporation upon a liquidation, dissolution or winding up, subject to prior rights and privileges attaching to the preference shares.

Under the dividend reinvestment and share purchase plan of the Corporation, registered shareholders may reinvest their dividends in additional common shares of the Corporation or make optional cash payments to purchase additional common shares, in either case, free of brokerage or other charges.

The registrar and transfer agent for the common shares in Canada is AST Trust Company (Canada) (formerly CST Trust Company) at its principal transfer offices in Vancouver, British Columbia, Calgary, Alberta, Toronto, Ontario and Montréal, Québec. The co-registrar and co-transfer agent for the common shares in the United States is American Stock Transfer & Trust CO LLC at its principal office in Brooklyn, New York.

Shareholder Rights Plan

The Corporation has a shareholder rights plan (the “Shareholder Rights Plan”) that is designed to encourage the fair treatment of shareholders in connection with any take-over bid for the Corporation. Rights issued under the Shareholder Rights Plan become exercisable when a person, and any related parties, acquires or announces the intention to acquire 20% or more of the Corporation’s outstanding common shares without complying with certain provisions set out in the Shareholder Rights Plan or without approval of the board of directors of the Corporation. Should such an acquisition or announcement occur, each rights holder, other than the acquiring person and its related parties, will have the right to purchase common shares of the Corporation at a 50% discount to the market price at that time. For further particulars, reference should be made to the Shareholder Rights Plan, a copy of which may be obtained by contacting the Director, Investor Relations, Enbridge, 200, 425-1st Street S.W., Calgary, Alberta, T2P 3L8; telephone: 1-800-481-2804; fax: 1-403-231-5780; email: investor.relations@enbridge.com.

Preference Shares

Shares Issuable in Series

The preference shares may be issued at any time or from time to time in one or more series. Before any shares of a series are issued, the board of directors of the Corporation shall fix the number of shares that will form such series and shall, subject to the limitations set out in the articles of the Corporation, determine the designation, rights, privileges, restrictions and conditions to be attached to the preference shares of such series, except that no series shall be granted the right to vote at a general meeting of the shareholders of the Corporation or the right to be convertible or exchangeable for common shares, directly or indirectly.

For preference shares issued that are to be convertible into other securities of the Corporation, including other series of preference shares, no amounts will be payable to convert those preference shares.

Priority

The preference shares of each series shall rank on parity with the preference shares of every other series with respect to dividends and return of capital and shall be entitled to a preference over the common shares and over any

15

Table of Contents

other shares ranking junior to the preference shares with respect to priority in payment of dividends and in the distribution of assets in the event of liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or any other distribution of the assets of the Corporation among its shareholders for the purpose of winding-up its affairs.

Voting Rights

Except as required by law, holders of the preference shares as a class shall not be entitled to receive notice of, to attend or to vote at any meeting of the shareholders of the Corporation, provided that the rights, privileges, restrictions and conditions attached to the preference shares as a class may be added to, changed or removed only with the approval of the holders of the preference shares given in such manner as may then be required by law, at a meeting of the holders of the preference shares duly called for that purpose.

CERTAIN INCOME TAX CONSIDERATIONS

The applicable Prospectus Supplement will describe material Canadian federal income tax consequences to an investor of acquiring any Securities offered thereunder, if applicable, including whether the payments of dividends on common shares or preference shares or payments of principal, premium, if any, and interest on debt securities payable to a non-resident of Canada will be subject to Canadian non-resident withholding tax.

The applicable Prospectus Supplement will also describe material United States federal income tax consequences of the acquisition, ownership and disposition of any Securities offered thereunder by an initial investor who is a United States person (within the meaning of the United States Internal Revenue Code), including, to the extent applicable, any such material consequences relating to debt securities payable in a currency other than the U.S. dollar, issued at an original issue discount for United States federal income tax purposes or containing early redemption provisions or other special items.

17

Table of Contents

PLAN OF DISTRIBUTION

The Corporation may sell the Securities to or through underwriters, agents or dealers and also may sell the Securities directly to purchasers pursuant to applicable statutory exemptions or through agents.

The distribution of the Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, or at prices related to such prevailing market prices to be negotiated with purchasers.

The Prospectus Supplement relating to each series of the Securities will also set forth the terms of the offering of the Securities, including to the extent applicable, the initial offering price, the proceeds to the Corporation, the underwriting concessions or commissions, and any other discounts or concessions to be allowed or re-allowed to dealers. Underwriters or agents with respect to Securities sold to or through underwriters or agents will be named in the Prospectus Supplement relating to such Securities.

In connection with the sale of the Securities, underwriters may receive compensation from the Corporation or from purchasers of the Securities for whom they may act as agents in the form of discounts, concessions or commissions. Any such commissions will be paid either using a portion of the funds received in connection with the sale of the Securities or out of the general funds of the Corporation.

Under agreements which may be entered into by the Corporation, underwriters, dealers and agents who participate in the distribution of the Securities may be entitled to indemnification by the Corporation against certain liabilities, including liabilities under securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.

In connection with any offering of Securities, the underwriters, agents or dealers may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at levels above those which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time.

ENFORCEMENT OF CIVIL LIABILITIES

The Corporation is a Canadian corporation. While the Corporation has appointed Enbridge (U.S.) Inc. as its agent to receive service of process with respect to any action brought against it in any federal or state court in the United States arising from any offering conducted under this Prospectus, it may not be possible for investors to enforce outside the United States judgments against the Corporation obtained in the United States in any such actions, including actions predicated upon the civil liability provisions of the United States federal and state securities laws. In addition, certain of the directors and officers of the Corporation are residents of Canada or other jurisdictions outside of the United States, and all or a substantial portion of the assets of those directors and officers are or may be located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon those persons, or to enforce against them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of United States federal and state securities laws.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors and Officers.

Section 34 of By-law No. 1 of Enbridge Inc. (“Enbridge” or the “Corporation”) provides, with regard to indemnity and insurance under the Canada Business Corporations Act (the “CBCA” or the “Act”), in part as follows:

“Indemnity of directors, officers and others. Subject to the limitations contained in the Act but without limit to the right of the Corporation to indemnify as provided for in the Act, the Corporation shall indemnify a director or officer, a former director or officer, or another individual who acts or acted at the Corporation’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the Corporation or other entity, if the individual:

(a) acted honestly and in good faith with a view to the best interests of the Corporation or, as the case may be, to the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at the Corporation’s request; and

(b) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that the individual’s conduct was lawful.”

The CBCA provides that a corporation may indemnify a director or officer, a former director or officer, or another individual who acts or acted at the corporation’s request as a director or officer, or an individual acting in a similar capacity, of another entity (collectively an “Indemnified Person”) against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the Indemnified Person in respect of any civil, criminal, administrative, investigative or other proceeding (other than an action by or on behalf of Enbridge to procure a judgment in its favor) in which the Indemnified Person is involved because of that association with Enbridge or other entity, if the Indemnified Person satisfies the conditions set forth above in paragraphs (a) and (b). In respect of an action by or on behalf of Enbridge or other entity to procure a judgment in its favor, Enbridge, with the approval of a court, may indemnify an Indemnified Person against all costs, charges and expenses reasonably incurred by an Indemnified Person in connection with such action, if the Indemnified Person satisfies the conditions set forth above in paragraphs (a) and (b). Notwithstanding the foregoing, an Indemnified Person is entitled to indemnification from Enbridge in respect of all costs, charges and expenses reasonably incurred by such Indemnified Person in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which such Indemnified Person is made a party by reason of such Indemnified Person’s association with Enbridge or such other entity, if such Indemnified Person satisfies the conditions set forth above in paragraphs (a) and (b) and was not judged by the court or other competent authority to have committed any fault or omitted to do anything that such Indemnified Person ought to have done.

As authorized by Section 35 of By-law No. 1, Enbridge has an insurance policy which indemnifies directors and officers against certain liabilities incurred by them in their capacities as such, including among other things, certain liabilities under the U.S. Securities Act.

Underwriting agreements in respect of offerings of securities under this registration statement may contain provisions by which the underwriters agree to indemnify the Corporation, each of the directors and officers of the Corporation and each person who controls the Corporation within the meaning of the U.S. Securities Act with respect to information furnished by the underwriters for use in the registration statement.

Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant

has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 10. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Act or Rule 3-19 of Regulation S-X if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is

II-4

Table of Contents

first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of an undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of an undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of an undersigned registrant or used or referred to by an undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about an undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by an undersigned registrant to the purchaser.

(7) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(8) To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, that registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
