federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial
owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor, member or beneficial
owner been the Holder of such 2025 Note.


 


The Company will furnish to the Holders of
the 2025 Notes by mail, within 30 days after the date of the payment of any Canadian Taxes is due under applicable law, certified

extent that, in such context additional amounts are, were or would be payable in respect thereof.

of any applicable political subdivision or taxing authority or (B) any amendment to or change in an interpretation or application
of such laws or regulations by any legislative body, court, governmental agency or regulatory authority announced or becoming effective
on or after November 13, 2019, the Company has or will become obligated to pay, on the next Interest Payment Date for the 2025
Notes, additional amounts with respect to any notes of the series as described above, or (2) on or after November 13, 2019, any
action has been taken by any taxing authority of, or any decision has been rendered by a court in, Canada (or the Company’s
successor’s jurisdiction of organization) or any applicable political subdivision or taxing authority, including any of those
actions specified in (1) above, whether or not the action was taken or decision rendered with respect to the Company, or any change,
amendment, application or interpretation is officially proposed, which, in the opinion of the Company’s counsel, will result

penalties, interest and other liabilities related thereto) imposed by the government of Canada (or any political subdivision or
taxing authority thereof or therein) (collectively, “Canadian Taxes”) upon or as a result of such payment, will not
be less than the amount provided in the 2029 Notes to be then due and payable (and the Company shall remit the full amount withheld
to the relevant authority in accordance with applicable law); provided, however, that the Company will not be required
to make any payment of additional amounts:


 


		(a)	to any person in respect of whom such taxes are required to be withheld or deducted as a result of such person or any other
person that has a beneficial interest in respect of any payment under the 2029 Notes not dealing at arm’s length with the
Company (within the meaning of the Income Tax Act (Canada)), (ii) being a “specified shareholder” (as defined
in subsection 18(15) of the Income Tax Act (Canada)) of the Company, or (iii) not dealing at arm’s length (for the
purposes of the Income Tax Act (Canada)) with such a “specified shareholder”;



 


		(b)	to any person by reason of such person being connected with Canada (otherwise than merely by holding or ownership of a 2029
Note or receiving any payments or exercising any rights thereunder), including without limitation a non-resident insurer who carries
on an insurance business in Canada and in a country other than Canada;



 


		(c)	for or on account of any tax, assessment or other governmental charge which would not have been so imposed but for: (i) the
presentation by the Holder of a 2029 Note for payment on a date more than 30 days after the date on which such payment became due
and payable or the date on which payment thereof is duly provided for, whichever occurs later; or (ii) the Holder’s failure
to comply with any certification, identification, information, documentation or other reporting requirements if compliance is required
by law, regulation, administrative practice or an applicable treaty as a precondition to exemption from or a reduction in the rate
of deduction or withholding of, any such taxes, assessment or charge;



 


		(d)	for or on account of any estate, inheritance, gift, sales, transfer, personal property tax or any similar tax, assessment or
other governmental charge;

payment to a person on a 2029 Note if such payment can be made to such person without such withholding by at least one other Paying
Agent the identity of which is provided to such person;



 


		(f)	for or on account of any tax, assessment or other governmental charge which is payable otherwise than by withholding from a
payment on a 2029 Note; or



 


		(g)	for any combination of items (a), (b), (c), (d), (e) and (f);



 


nor will additional amounts be paid with respect to any payment
on a 2029 Note to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent
such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the income for Canadian
federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial
owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor, member or beneficial
owner been the Holder of such 2029 Note.


 


The Company will furnish to the Holders of
the 2029 Notes by mail, within 30 days after the date of the payment of any Canadian Taxes is due under applicable law, certified
copies of tax receipts or other documents evidencing such payment.


 


Wherever in the 2029 Notes or the Indenture
there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount payable under
or with respect to the 2029 Notes, such mention shall be deemed to include mention of the payment of additional amounts to the
extent that, in such context additional amounts are, were or would be payable in respect thereof.


 


		(11)	Tax Redemption: The 2029 Notes will be subject to redemption at any time at a Redemption Price equal to the principal
amount of the 2029 Notes, together with accrued and unpaid interest to the 2029 Redemption Date, upon the giving of notice by first-class
mail at least 10 days, but not more than 60 days, before the 2029 Redemption Date to each Holder of the 2029 Notes to be redeemed,
if the Company (or its successor) determines that (1) as a result of (A) any amendment to or change (including any announced prospective
change) in the laws or related regulations of Canada (or the Company’s successor’s jurisdiction of organization) or
of any applicable political subdivision or taxing authority or (B) any amendment to or change in an interpretation or application
of such laws or regulations by any legislative body, court, governmental agency or regulatory authority announced or becoming effective
on or after November 13, 2019, the Company has or will become obligated to pay, on the next Interest Payment Date for the 2029
Notes, additional amounts with respect to any notes of the series as described above, or (2) on or after November 13, 2019, any
action has been taken by any taxing authority of, or any decision has been rendered by a court in, Canada (or the Company’s
successor’s jurisdiction of organization) or any applicable political subdivision or taxing authority, including any of those
actions specified in (1) above, whether or not the action was taken or decision rendered with respect to the Company, or any change,
amendment, application or interpretation is officially proposed, which, in the opinion of the Company’s counsel, will result
in the Company becoming obligated to pay, on the next Interest Payment Date, additional amounts with respect to any note of the
series, and the Company has determined that the obligation cannot be avoided by the use of reasonable available measures.

		a.	100% of the principal amount of the 2049 Notes to be redeemed, and



 


		b.	the sum of the present values of the remaining scheduled payments of principal and interest on the 2049 Notes to be redeemed
(assuming that such 2049 Notes matured on May 15, 2049, the date that is six months prior to Maturity of the 2049 Notes), not including
any portion of the payments of interest accrued as of the date fixed for redemption of the 2049 Notes (the “2049 Redemption

2049 Redemption Date will be payable to the Holders of 2049 Notes registered at the close of business on the relevant record dates
according to the terms and provisions of the Indenture.


 


Notice of any redemption will be delivered
by first-class mail at least 10 days, but not more than 60 days, before the 2049 Redemption Date to each Holder of the 2049

the notice of redemption relating to such 2049 Note shall state the portion of the principal amount thereof to be redeemed; provided
that no 2049 Note in an aggregate principal amount of US$1,000 or less shall be redeemed in part. A replacement 2049 Note in

“Comparable Treasury Issue” means
the United States Treasury security or securities selected by the Quotation Agent as having an actual or interpolated maturity
comparable to the remaining term of the 2049 Notes to be redeemed (assuming that such 2049 Notes matured on May 15, 2049, the date
that is six months prior to Maturity of the 2049 Notes) that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of
the 2049 Notes.


 


“Comparable Treasury Price” means,
with respect to any 2049 Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date,
after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer
than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means
each of Barclays Capital Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and a Primary Treasury Dealer
(as defined below) selected by SMBC Nikko Securities America, Inc., and their respective successors; provided , however , that
if such entity or its successor shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary
Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a
Primary Treasury Dealer.


 


“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any 2049 Redemption Date, the average, as determined by the Reference
Treasury Dealer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 3:30 p.m. (New York time) on the third business
day preceding such Redemption Date.

such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; or (ii)
the Holder’s failure to comply with any certification, identification, information, documentation
or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as
a precondition to exemption from or a reduction in the rate of deduction or withholding of, any such taxes, assessment or charge;

		(f)	for or on account of any tax, assessment or other governmental charge which is payable otherwise
than by withholding from a payment on a Note; or

nor will additional amounts be paid with respect
to any payment on a Note to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the
income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor,
member or beneficial owner been the Holder of such Note.


 


The Company will furnish
to the Holders of the Notes by mail, within 30 days after the date of the payment of any Canadian Taxes is due under applicable
law, certified copies of tax receipts or other documents evidencing such payment.

payable under or with respect to the Notes, such mention shall be deemed to include mention of the payment of additional amounts
to the extent that, in such context additional amounts are, were or would be payable in respect thereof.


 


The Company may, at any time,
and from time to time, issue additional Notes under the Indenture in unlimited amounts having the same terms as this Note, and

		·	the sum of the present values of the
remaining scheduled payments of principal and interest on the Notes to be redeemed (assuming that such Notes matured on December
15, 2024, the date that is one month prior to Maturity of the Notes), not including any portion of the payments of interest accrued
as of the Redemption Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Adjusted Treasury Rate (as defined below) plus 15 basis points,

Note.

defined terms apply:

any decision has been rendered by a court in, Canada (or the Company’s successor’s jurisdiction of organization) or
any applicable political subdivision or taxing authority, including any of those actions specified in (1) above, whether or not
the action was taken or decision rendered with respect to the Company, or any change, amendment, application or interpretation
is officially proposed, which, in the opinion of the Company’s counsel, will result in the Company becoming obligated to
pay, on the next Interest Payment Date, additional amounts with respect to any Note of the series, and the Company has determined
that the obligation cannot be avoided by the use of reasonable available measures.

4.000% Senior Notes due

2049


 


This Security is one of a
duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be issued in one or more
series under an Indenture, dated as of February 25, 2005, between the Company and Deutsche Bank Trust Company Americas, as Trustee
(herein called the “Trustee,” which term includes any successor trustee under the Indenture), as amended and supplemented
by the First Supplemental Indenture, dated as of March 1, 2012, between the Company and the Trustee, and as further amended
and supplemented by the Sixth Supplemental Indenture, dated as of May 13, 2019, among the Company, Spectra Energy Partners, LP
(“SEP”), Enbridge Energy Partners, L.P. (“EEP” and, together with SEP, the “Guarantors”) and
the Trustee (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), and
reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Guarantors, the Trustee and the Holders of the Notes and of the terms upon which the Notes are,
and are to be, authenticated and delivered. This Note is one of the series designated as the 4.000% Senior Notes due 2049 of the
Company, issued in initial aggregate principal amount of $500,000,000.


 


The Company will, subject
to the exceptions and limitations set forth below, pay to the Holder of a Note who is a non-resident of Canada under the Income
Tax Act (Canada) such additional amounts as may be necessary so that every net payment on such Note, after deduction or withholding
by the Company or of any Paying Agent for or on account of any present or future tax, assessment or other governmental charge (including
penalties, interest and other liabilities related thereto) imposed by the government of Canada (or any political subdivision or
taxing authority thereof or therein) (collectively, “Canadian Taxes”) upon or as a result of such payment, will not
be less than the amount provided in the Notes to be then due and payable (and the Company shall remit the full amount withheld
to the relevant authority in accordance with applicable law); provided, however, that the Company will not be required
to make any payment of additional amounts:


 


		(a)	to any person in respect of whom such taxes are required to be withheld or deducted as a result
of such person or any other person that has a beneficial interest in respect of any payment under the Notes not dealing at arm’s
length with the Company (within the meaning of the Income Tax Act (Canada)), (ii) being a “specified shareholder”
(as defined in subsection 18(15) of the Income Tax Act (Canada)) of the Company, or (iii) not dealing at arm’s length
(for the purposes of the Income Tax Act (Canada)) with such a “specified shareholder”;



 


		(b)	to any person by reason of such person being connected with Canada (otherwise than merely by
holding or ownership of a Note or receiving any payments or exercising any rights thereunder), including without limitation a non-resident
insurer who carries on an insurance business in Canada and in a country other than Canada;



 






    	 	D-5-	 



    


    

 


		(c)	for or on account of any tax, assessment or other governmental charge which would not have been
so imposed but for: (i) the presentation by the Holder of a Note for payment on a date more than 30 days after the date on which
such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; or (ii)
the Holder’s failure to comply with any certification, identification, information, documentation
or other reporting requirements if compliance is required by law, regulation, administrative practice or an applicable treaty as
a precondition to exemption from or a reduction in the rate of deduction or withholding of, any such taxes, assessment or charge;



 


		(d)	for or on account of any estate, inheritance, gift, sales, transfer, personal property tax or
any similar tax, assessment or other governmental charge;



 


		(e)	for or on account of any tax, assessment or other governmental charge required to be withheld
by any Paying Agent from any payment to a person on a Note if such payment can be made to such person without such withholding
by at least one other Paying Agent the identity of which is provided to such person;



 


		(f)	for or on account of any tax, assessment or other governmental charge which is payable otherwise
than by withholding from a payment on a Note; or



 


		(g)	for any combination of items (a), (b), (c), (d), (e) and (f);



 


nor will additional amounts be paid with respect
to any payment on a Note to a Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the
income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to payment of the additional amounts had such beneficiary, settlor,
member or beneficial owner been the Holder of such Note.


 


The Company will furnish
to the Holders of the Notes by mail, within 30 days after the date of the payment of any Canadian Taxes is due under applicable
law, certified copies of tax receipts or other documents evidencing such payment.


 


Wherever in this Note or
the Indenture there is mentioned, in any context, the payment of principal (and premium, if any), interest or any other amount
payable under or with respect to the Notes, such mention shall be deemed to include mention of the payment of additional amounts
to the extent that, in such context additional amounts are, were or would be payable in respect thereof.


 


The Company may, at any time,
and from time to time, issue additional Notes under the Indenture in unlimited amounts having the same terms as this Note, and
such additional Notes will, together with this Note and any Notes which may be issued in exchange or substitution herefor, constitute
a single series of Notes under the Indenture.


 






    	 	D-6-	 



    


    

 


Prior to the date that is
six months prior to Maturity, the Notes of this series will be subject to redemption, in whole or in part, at the Company’s
option at any time, or from time to time, at a Redemption Price equal to the greater of:


 


		·	100% of the principal amount of the Notes to be redeemed, and



		·	the sum of the present values of the
remaining scheduled payments of principal and interest on the Notes to be redeemed (assuming that such Notes matured on May 15,
2049, the date that is six months prior to Maturity of the Notes), not including any portion of the payments of interest accrued
as of the Redemption Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve
30-day months) at the Adjusted Treasury Rate (as defined below) plus 30 basis points,



 


plus, in either case, accrued interest on the
principal amount being redeemed to the Redemption Date. The Redemption Price for the Notes to be redeemed on any Redemption Date
that is on or after the date that is six months prior to Maturity of the Notes will be equal to 100% of the principal amount of
the Notes being redeemed, plus accrued and unpaid interest on the principal amount being redeemed to the Redemption Date.


 


Notwithstanding the foregoing,
installments of interest on Notes being redeemed that are due and payable on Interest Payment Dates falling on or prior to the
relevant Redemption Date will be payable to the Holders of Notes registered at the close of business on the relevant record dates
according to the terms and provisions of the Indenture.


 


Notice of any redemption
will be delivered by first-class mail at least 10 days, but not more than 60 days, before the Redemption Date to each Holder of
the Notes to be redeemed.


 


Unless
the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the
Notes or portions of the Notes called for redemption.


 


In the case of a partial
redemption of Notes, selection of such Notes for redemption will be made on a pro rata basis. If any Note is redeemed in part,
the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed; provided
that no Note in an aggregate principal amount of US$1,000 or less shall be redeemed in part. A replacement Note in the principal
amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original
Note.


 


In connection with such optional redemption, the
following defined terms apply:


 


“Adjusted
Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield
to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable
Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the Redemption
Date.


 






    	 	D-7-	 



    


    

 


“Comparable Treasury
Issue” means the United States Treasury security or securities selected by the Quotation Agent as having an actual or interpolated
maturity comparable to the remaining term of the Notes to be redeemed (assuming that such Notes matured on May 15, 2049, the date
that is six months prior to Maturity of the Notes) that would be utilized, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes.


 


“Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption
Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains
fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.


 


“Quotation Agent”
means one of the Reference Treasury Dealers, which is appointed by the Company.


 


“Reference Treasury Dealer” means
each of Barclays Capital Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and a Primary Treasury Dealer
(as defined below) selected by SMBC Nikko Securities America, Inc., and their respective successors; provided , however , that
if such entity or its successor shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary
Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a
Primary Treasury Dealer.


 


“Reference Treasury Dealer Quotations”
means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Reference Treasury
Dealer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal
amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 3:30 p.m. (New York time) on the third business
day preceding such Redemption Date.


 


In the event of redemption
of this Note in part only, a new Note or Notes of this series and of like tenor for the unredeemed portion hereof will be issued
in the name of the Holder hereof upon the cancellation hereof.


 


The Notes of this series
will be subject to redemption at any time at a Redemption Price equal to the principal amount of the Notes, together with accrued
and unpaid interest to the Redemption Date, upon the giving of notice by first-class mail at least 10 days, but not more than 60
days, before the Redemption Date to each Holder of the Notes to be redeemed, if the Company (or its successor) determines that
(1) as a result of (A) any amendment to or change (including any announced prospective change) in the laws or related regulations
of Canada (or the Company’s successor’s jurisdiction of organization) or of any applicable political subdivision or
taxing authority or (B) any amendment to or change in an interpretation or application of such laws or regulations by any legislative
body, court, governmental agency or regulatory authority announced or becoming effective on or after November 13, 2019, the Company
has or will become obligated to pay, on the next Interest Payment Date for the Notes, additional amounts with respect to any Notes
of the series as described above, or (2) on or after November 13, 2019, any action has been taken by any taxing authority of, or
any decision has been rendered by a court in, Canada (or the Company’s successor’s jurisdiction of organization) or
any applicable political subdivision or taxing authority, including any of those actions specified in (1) above, whether or not
the action was taken or decision rendered with respect to the Company, or any change, amendment, application or interpretation
is officially proposed, which, in the opinion of the Company’s counsel, will result in the Company becoming obligated to
pay, on the next Interest Payment Date, additional amounts with respect to any Note of the series, and the Company has determined
that the obligation cannot be avoided by the use of reasonable available measures.
