the accompanying base prospectus relate to the issuance and sale from time to time of common units representing limited partner interests in Plains All American Pipeline, L.P. having an aggregate offering price of up to $750,000,000 through one or
more of our sales agents. These sales, if any, will be made pursuant to the terms of the equity distribution agreement dated May 28, 2013 between us and the sales agents, which has been filed as an exhibit to a Current Report on Form&nbsp;8-K that
we filed with the Securities and Exchange Commission. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Under the terms of the equity distribution agreement, we also may sell
common units to any sales agent as principal for its own account at a price agreed upon at the time of the sale. If we sell common units to any such sales agent as principal, we will enter into a separate terms agreement with such sales agent and we
will describe that agreement in a separate prospectus supplement or pricing supplement. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Our common units trade on the New

be made by means of ordinary brokers&#146; transactions through the facilities of the NYSE at market prices, in block transactions or as otherwise agreed between us and one or more of the sales agents. </FONT></P>

consider the risks relating to investing in our common units and each of the risk factors described under &#147;<A HREF="#supprom542969_4">Risk Factors</A>&#148; on page S-4 of this prospectus supplement before you make an investment in our

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We are a Delaware limited partnership formed in September&nbsp;1998. Our operations are conducted directly and indirectly through our
primary operating subsidiaries. We engage in the transportation, storage, terminalling and marketing of crude oil and refined products, as well as in the processing, transportation, fractionation, storage and marketing of natural gas liquids
(&#147;NGL&#148;). The term NGL includes ethane and natural gasoline products as well as propane and butane, products which are commonly referred to as liquefied petroleum gas (&#147;LPG&#148;). </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We also own and operate natural gas storage facilities through our direct and indirect ownership of PAA Natural Gas Storage, L.P.
(&#147;PNG&#148;), which is a fee-based, growth-oriented Delaware limited partnership engaged in the ownership, acquisition, development, operation and commercial management of natural gas storage facilities. We own PNG&#146;s general partner, PNGS
GP LLC, which holds a 2% general partner interest in PNG and all of its incentive distribution rights. We also currently own an approximate 61% limited partner interest in PNG. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We are one of the largest midstream crude oil companies in North America. We have an extensive network of pipeline transportation,
terminalling, storage and gathering assets in key oil-producing basins and transportation corridors, and at major market hubs in the United States and Canada. We manage our operations through three primary operating segments: transportation,
facilities and supply and logistics. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>Ongoing Acquisition Activities </B></FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Consistent with our business strategy, we are continuously engaged in discussions with potential sellers regarding the possible purchase
of assets and operations that are strategic and complementary to our existing operations. In addition, we have in the past evaluated and pursued, and intend in the future to evaluate and pursue, other energy-related assets that have characteristics
and opportunities similar to our existing business lines and enable us to leverage our assets, knowledge and skill sets. Such acquisition efforts may involve participation by us in processes that have been made public and involve a number of
potential buyers, commonly referred to as &#147;auction&#148; processes, as well as situations in which we believe we are the only party or one of a limited number of potential buyers in negotiations with the potential seller. These acquisition
efforts often involve assets which, if acquired, could have a material effect on our financial condition and results of operations. </FONT></P>

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">All prospective unitholders are encouraged to consult with their own tax advisors about the federal, state, local and foreign tax
consequences particular to their own circumstances. In particular, ownership of common units by tax-exempt entities, including employee benefit plans and IRAs, and non-U.S. investors raises issues unique to such persons. The relevant rules are
complex, and the discussions herein and in the accompanying base prospectus do not address tax considerations applicable to tax-exempt entities and non-U.S. investors, except as specifically set forth in the accompanying base prospectus. Please read

Rates </B></FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Beginning January&nbsp;1, 2013, the highest marginal U.S. federal income tax rates for individuals applicable to
ordinary income and long-term capital gains (generally, gains from the sale or exchange of certain investment assets held for more than one year) are 39.6% and 20%, respectively. These rates are subject to change by new legislation at any time.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">In addition, a 3.8% Medicare tax on certain net investment income earned by individuals, estates, and trusts applies for
taxable years beginning after December&nbsp;31, 2012. For these purposes, net investment income generally includes a unitholder&#146;s allocable share of our income and gain realized by a unitholder from a sale of units. In the case of an
individual, the tax will be imposed on the lesser of (i)&nbsp;the unitholder&#146;s net investment income from all investments, or (ii)&nbsp;the amount by which the unitholder&#146;s modified adjusted gross income exceeds $250,000 (if the unitholder
is married and filing jointly or a surviving spouse), $125,000 (if married filing separately) or $200,000 (if the unitholder is unmarried or in any other case). In the case of an estate or trust, the tax will be imposed on the lesser of
(i)&nbsp;undistributed net investment income, or (ii)&nbsp;the excess adjusted gross income over the dollar amount at which the highest income tax bracket applicable to an estate or trust begins. </FONT></P>

<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">This section summarizes the material U.S. federal income tax consequences that may be relevant to prospective unitholders and is based
upon current provisions of the U.S. Internal Revenue Code of 1986, as amended (the &#147;Code&#148;), existing and proposed U.S. Treasury regulations thereunder (the &#147;Treasury Regulations&#148;), and current administrative rulings and court
decisions, all of which are subject to change. Changes in these authorities may cause the federal income tax consequences to a prospective unitholder to vary substantially from those described below. Unless the context otherwise requires, references
in this section to &#147;we&#148; or &#147;us&#148; are references to the partnership and its subsidiaries. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Legal conclusions
contained in this section, unless otherwise noted, are the opinion of Vinson&nbsp;&amp; Elkins L.L.P. and are based on the accuracy of representations made by us to them for this purpose. However, this section does not address all federal income tax
matters that affect us or our unitholders. Furthermore, this section focuses on unitholders who are individual citizens or residents of the United States (for federal income tax purposes), who have the U.S. dollar as their functional currency and
who hold units as capital assets (generally, property that is held for investment). This section has limited applicability to corporations, partnerships (including entities treated as partnerships for U.S. federal income tax purposes), estates,
trusts, non-resident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, non-U.S. persons, individual retirement accounts (&#147;IRAs&#148;), employee benefit plans, real estate investment trusts or
mutual funds. <B><I>Accordingly, we encourage each unitholder to consult the unitholder&#146;s own tax advisor in analyzing the federal, state, local and non-U.S. tax consequences particular to that unitholder resulting from ownership or disposition
of units.</I></B> </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">We are relying on opinions and advice of Vinson&nbsp;&amp; Elkins L.L.P. with respect to the matters
described herein. An opinion of counsel represents only that counsel&#146;s best legal judgment and does not bind the IRS or a court. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS. Any
such contest of the matters described herein may materially and adversely impact the market for our units and the prices at which units trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders and our
general partner because the costs will reduce our cash available for distribution. Furthermore, the tax consequences of an investment in us, may be significantly modified by future legislative or administrative changes or court decisions, which may
be retroactively applied. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">For the reasons described below, Vinson&nbsp;&amp; Elkins L.L.P. has not rendered an opinion with
respect to the following federal income tax issues: (1)&nbsp;the treatment of a unitholder whose units are the subject of a securities loan (e.g., a loan to a short seller to cover a short sale of units) (please read &#147;&#151; Tax Consequences of
Unit Ownership &#151; Treatment of Securities Loans&#148;); (2)&nbsp;whether our monthly convention for allocating taxable income and losses is permitted by existing Treasury Regulations (please read &#147;&#151; Disposition of Units &#151;
Allocations Between Transferors and Transferees&#148;); and (3)&nbsp;whether our method for taking into account Section&nbsp;743 adjustments is sustainable in certain cases (please read &#147;&#151; Tax Consequences of Unit Ownership &#151;
Section&nbsp;754 Election&#148; and &#147;&#151; Uniformity of Units&#148;). </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B><I>Taxation of the Partnership </I></B></FONT></P>

STYLE="font-family:Times New Roman" SIZE="2">We expect to be treated as a partnership for U.S. federal income tax purposes and, therefore, generally will not be liable for such taxes. Instead, as described below, each of our unitholders will take
into account its respective share of our items of income, gain, loss and deduction in computing its federal income tax liability as if the unitholder had earned such income directly, even if we make no cash distributions to the unitholder.
Distributions we make to a unitholder generally will not give rise to income or gain taxable to such unitholder, unless the amount of cash distributed exceeds the unitholder&#146;s adjusted tax basis in its units. </FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Section&nbsp;7704 of the Code generally provides that publicly-traded partnerships will be
treated as corporations for federal income tax purposes. However, if 90% or more of a partnership&#146;s gross income for every taxable year it is publicly-traded consists of &#147;qualifying income,&#148; the partnership may continue to be treated
as a partnership for federal income tax purposes (the &#147;Qualifying Income Exception&#148;). Qualifying income includes (i)&nbsp;income and gains derived from processing, transportation, storage, terminalling, and marketing of any natural
resource, including crude oil, natural gas, and products thereof, (ii)&nbsp;interest (other than from a financial business), (iii)&nbsp;dividends, (iv)&nbsp;gains from the sale of real property and (v)&nbsp;gains from the sale or other disposition
of capital assets held for the production of qualifying income. We estimate that less than 5 percent of our current gross income is not qualifying income; however, this estimate could change from time to time. </FONT></P>

cured within a reasonable time after discovery (in which case the IRS may also require us to make adjustments with respect to our unitholders or pay other amounts), we will be treated as transferring all of our assets, subject to liabilities, to a
newly formed corporation, on the first day of the year in which we fail to meet the Qualifying Income Exception, in exchange for stock in that corporation and then as distributing that stock to our unitholders in liquidation. This deemed
contribution and liquidation should not result in the recognition of taxable income by our unitholders or us so long as our liabilities do not exceed the tax basis of our assets. Thereafter, we would be treated as an association taxable as a
corporation for federal income tax purposes. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">If for any reason we are taxable as a corporation in any taxable year, our items
of income, gain, loss and deduction would be taken into account by us in determining the amount of our liability for federal income tax, rather than being passed through to our unitholders. Our taxation as a corporation would materially reduce the
cash available for distribution to unitholders and thus would likely substantially reduce the value of our units. Any distribution made to a unitholder at a time we are treated as a corporation would be (i)&nbsp;a taxable dividend to the extent of
our current or accumulated earnings and profits, then (ii)&nbsp;a nontaxable return of capital to the extent of the unitholder&#146;s tax basis in its stock that was exchanged for units, and thereafter (iii)&nbsp;taxable capital gain. </FONT></P>

share of income, gain, loss and deduction. We cannot assure our unitholders that those positions will yield a result that conforms to all of the requirements of the Code, Treasury Regulations or administrative interpretations of the IRS. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The IRS may audit our federal income tax information returns. Neither we, nor Vinson&nbsp;&amp; Elkins L.L.P. can assure prospective
unitholders that the IRS will not successfully challenge the positions we adopt, and such a challenge could adversely affect the value of the units. Adjustments resulting from an IRS audit may require each unitholder to adjust a prior year&#146;s
tax liability and may result in an audit of the unitholder&#146;s own return. Any audit of a unitholder&#146;s return could result in adjustments unrelated to our returns. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Publicly traded partnerships generally are treated as entities separate from their owners for purposes of federal income tax audits, judicial review of administrative adjustments by the IRS and tax
settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings of the partners. The Code requires that one partner be designated as
the &#147;Tax Matters Partner&#148; for these purposes, and our partnership agreement designates our general partner. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Tax
Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items in our returns. The Tax Matters Partner may bind a unitholder with less than a 1% profits interest in us to a settlement with the
IRS unless that unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the unitholders are bound, of a final partnership
administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any unitholder having at least a 1% interest in profits or by any group of unitholders having in the aggregate at least a 5%
interest in profits. However, only one action for judicial review may go forward, and each unitholder with an interest in the outcome may participate in that action. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT
STYLE="font-family:Times New Roman" SIZE="2">A unitholder must file a statement with the IRS identifying the treatment of any item on its federal income tax return that is not consistent with the treatment of the item on our return. Intentional or
negligent disregard of this consistency requirement may subject a unitholder to substantial penalties. </FONT></P>
