a definitive agreement concerning a transaction or, if such a definitive agreement is reached, will result in the
consummation of a transaction provided for in such definitive agreement. Discussions concerning a transaction may be
terminated at any time and without prior notice. Entry into a definitive agreement concerning a transaction and the
consummation of any such transaction is subject to a number of contingencies, which are beyond the control of Enbridge and
EUSI, including the satisfactory completion of due diligence, the approval of the board of directors of SEP GP LLC (the
&ldquo;<U>Issuer Board</U>&rdquo;), the recommendation of the conflicts committee established by the Issuer Board, approval
by holders of a majority of the outstanding Common Units of the Issuer, and the satisfaction of any conditions to the consummation of a

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Ladies and Gentlemen:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Enbridge Inc. (&ldquo;<U>Enbridge</U>&rdquo;) and Enbridge (U.S.)
Inc. (&ldquo;<U>EUS</U>&rdquo;) are pleased to submit this non-binding offer (this &ldquo;<U>Non-Binding Offer</U>&rdquo;) to Spectra
Energy Partners, LP (&ldquo;<U>SEP</U>&rdquo;) regarding a possible transaction pursuant to which Enbridge, through a wholly owned
subsidiary (&ldquo;<U>AcquireCo</U>&rdquo;), would acquire all of the outstanding Common Units of SEP not already owned by Enbridge
and its affiliates (the &ldquo;<U>Transaction</U>&rdquo;), as described in more detail below.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">As you are aware, Enbridge currently indirectly owns, through
various of its wholly owned subsidiaries, 402,989,862 SEP Common Units, representing 83.11% of the total outstanding Common Units
of SEP. In addition, Enbridge currently indirectly owns the non-economic general partner interest in SEP through its wholly owned
subsidiary Spectra Energy Partners (DE) GP, LP (&ldquo;<U>SEP GP LP</U>&rdquo;), the general partner of SEP. Subject to the negotiation
and execution of a definitive agreement containing terms and conditions customary for a transaction of the type set out in this
letter, we are pleased to offer 1.0123 Common Shares of Enbridge in exchange for each issued and outstanding publicly-held Common
Unit of SEP based upon the closing price of SEP&rsquo;s Common Units on the NYSE on May 16, 2018 as compared to the closing price
of an Enbridge Common Share on the same date.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">We believe this proposal is attractive to public holders of
SEP Common Units. In light of recent regulatory developments that have affected both SEP and the master limited partnership (&ldquo;<U>MLP</U>&rdquo;)
market in the U.S. more broadly, we are of the view that a combination transaction is the best strategic alternative currently
available to SEP to maximize value to all of its unitholders. We believe the proposed exchange ratio for SEP Common Units reflects
a fair value to the stand-alone value of SEP&rsquo;s Common Units today. In particular, the value offered for all of SEP&rsquo;s
outstanding publicly-traded Common Units takes into account the difficulty of supporting SEP&rsquo;s existing distribution levels
from 2019 on, given the combined impact of the announcement of the Federal Energy Regulatory Commission&rsquo;s income tax allowance
policy change and U.S. tax reform on MLP market valuations and the resulting impact on MLPs&rsquo; access to capital at reasonable
rates.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Enbridge&rsquo;s proposal offers unitholders a security with
enhanced trading liquidity and provides direct ownership in North America&rsquo;s largest energy infrastructure company with diverse,
safe and reliable cash flow generation supporting attractive dividend growth. In addition, the Transaction would permit current
SEP public unitholders the opportunity to participate in the future success of Enbridge as new Enbridge shareholders.</P>

1.0123 Common Shares of Enbridge for each issued and outstanding publicly-held Common Unit of SEP, as described above.</P>
