Notes&#148;) and $400,000,000 aggregate principal amount of its 5.800% Senior Notes due 2043 (the &#147;2043 Notes&#148; and, together with the 2023 Notes, the &#147;Notes&#148;). The Offering has been registered under the Securities Act of 1933, as
amended (the &#147;Securities Act&#148;), pursuant to a registration statement on Form S-3 (Registration No.&nbsp;333-179471) of the Partnership, and the prospectus supplement dated November&nbsp;12, 2013 and filed with the Securities and Exchange

&#147;Base Indenture&#148;), dated as of November&nbsp;9, 2010, between the Partnership and The Bank of New York Mellon Trust Company, N.A. as trustee (the &#147;Trustee&#148;), as supplemented by the Fourth Supplemental Indenture (the
&#147;Supplemental Indenture&#148; and together with the Base Indenture, the &#147;Indenture&#148;), dated as of November&nbsp;15, 2013, between the Partnership and the Trustee. Each series of Notes is represented by a global security, which is
included as an exhibit to the Supplemental Indenture. The Indenture contains covenants that, among other things, restrict the Partnership&#146;s ability to incur liens on assets to secure certain debt and merge, consolidate or transfer or lease all
or substantially all of its assets, subject to certain qualifications and exceptions. The Partnership may redeem some or all of the Notes of each series at any time or from time to time prior to August&nbsp;15, 2023, in the case of the 2023 Notes or
May&nbsp;15, 2043, in the case of the 2043 Notes, at a specified &#147;make whole&#148; premium for each series of Notes described in the Indenture. The Partnership also has the option, with respect to the 2023 Notes, at any time on or after
August&nbsp;15, 2023, and with respect to the 2043 Notes, at any time on or after May&nbsp;15, 2043, to redeem the Notes of such series, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes of such series to
be redeemed, plus accrued and unpaid interest thereon to the redemption date, as more fully described in the Indenture. A copy of the Base Indenture was previously filed, and a copy of the Supplemental Indenture is filed as Exhibit 4.1 to this
report. The descriptions of the terms of the Base Indenture and the Supplemental Indenture in this Item&nbsp;1.01 are qualified in their entirety by reference to such exhibits. </P>

The Notes are the Partnership&#146;s senior unsecured obligations and will rank equally in right of payment with all of its other senior indebtedness and senior to all of its future indebtedness that is expressly subordinated in right of payment to
the Notes. </P> <P STYLE="font-size:18pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

On November 15, 2013, Williams
Partners L.P. (the "Partnership") completed a $1.0 billion registered offering of debt securities (the "Offering") consisting of $600,000,000 aggregate principal amount of its 4.500% Senior Notes due 2023 (the "2023
Notes") and $400,000,000 aggregate principal amount of its 5.800% Senior Notes due 2043 (the "2043 Notes" and, together with the 2023 Notes, the "Notes"). The Offering has been registered under the Securities Act of 1933, as
amended (the "Securities Act"), pursuant to a registration statement on Form S-3 (Registration No. 333-179471) of the Partnership, and the prospectus supplement dated November 12, 2013 and filed with the Securities and Exchange
Commission pursuant to Rule 424(b) of the Securities Act on November 13, 2013.
The Notes were issued pursuant to an Indenture (the
"Base Indenture"), dated as of November 9, 2010, between the Partnership and The Bank of New York Mellon Trust Company, N.A. as trustee (the "Trustee"), as supplemented by the Fourth Supplemental Indenture (the
"Supplemental Indenture" and together with the Base Indenture, the "Indenture"), dated as of November 15, 2013, between the Partnership and the Trustee. Each series of Notes is represented by a global security, which is
included as an exhibit to the Supplemental Indenture. The Indenture contains covenants that, among other things, restrict the Partnership's ability to incur liens on assets to secure certain debt and merge, consolidate or transfer or lease all
or substantially all of its assets, subject to certain qualifications and exceptions. The Partnership may redeem some or all of the Notes of each series at any time or from time to time prior to August 15, 2023, in the case of the 2023 Notes or
May 15, 2043, in the case of the 2043 Notes, at a specified "make whole" premium for each series of Notes described in the Indenture. The Partnership also has the option, with respect to the 2023 Notes, at any time on or after
August 15, 2023, and with respect to the 2043 Notes, at any time on or after May 15, 2043, to redeem the Notes of such series, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes of such series to
be redeemed, plus accrued and unpaid interest thereon to the redemption date, as more fully described in the Indenture. A copy of the Base Indenture was previously filed, and a copy of the Supplemental Indenture is filed as Exhibit 4.1 to this
report. The descriptions of the terms of the Base Indenture and the Supplemental Indenture in this Item 1.01 are qualified in their entirety by reference to such exhibits.
The Notes will pay interest semi-annually in cash in arrears on May 15 and November 15 of each year, beginning on May 15, 2014.
The Notes are the Partnership's senior unsecured obligations and will rank equally in right of payment with all of its other senior indebtedness and senior to all of its future indebtedness that is expressly subordinated in right of payment to
the Notes.
