<p style="margin:0in 0in .0001pt;text-indent:24.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Plains All American Pipeline, L.P., a Delaware limited partnership (&#147;<u>PAA</u>&#148;), has entered into an Agreement and Plan of Merger dated as of October&nbsp;21, 2013 (the &#147;<u>Merger Agreement</u>&#148;), by and among PAA, PAA Acquisition Company LLC, a Delaware limited liability company and wholly-owned subsidiary of PAA (&#147;<u>MergerCo</u>&#148;), PAA Natural Gas Storage, L.P., a Delaware limited partnership (&#147;<u>PNG</u>&#148;), and PNGS GP LLC, a Delaware limited liability company and the general partner of PNG (&#147;<u>PNG GP</u>&#148;).</font></p>
<p style="margin:0in 0in .0001pt;text-indent:24.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:24.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The conflicts committee of the board of directors of PNG GP (the &#147;<u>PNG Conflicts Committee</u>&#148;) approved the Merger Agreement and the Merger Transactions (defined below) and determined that the Merger Agreement and the Merger Transactions are fair and reasonable to PNG and the holders of PNG common units (as defined below) unaffiliated with PAA. The PNG Conflicts Committee has caused PNG GP to approve the Merger Agreement and the Merger Transactions and directed that the Merger Agreement and the Merger Transactions be submitted to the unitholders of PNG at a special meeting of the unitholders for approval. The PNG Conflicts Committee recommended that the unitholders of PNG vote in favor of the proposal to approve the Merger Agreement and the Merger Transactions at the special meeting of the unitholders.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:24.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:24.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">PAA owns 100% of the membership interests in PNG GP, approximately 46% of PNG&#146;s 61.2 million outstanding common units (&#147;<u>PNG common units</u>&#148;) and all of the series A subordinated units and series B subordinated units (&#147;<u>PNG subordinated units</u>&#148;) representing limited partner interests in PNG. Pursuant to the Merger Agreement, MergerCo will merge with and into PNG at the effective time of the merger, with PNG surviving (the &#147;<u>Merger</u>&#148;), such that following the Merger, PNG GP will remain a wholly-owned subsidiary of PAA and the sole general partner of PNG, and PAA will be the sole limited partner of PNG. Except for the PNG common units owned by PAA, all PNG common units outstanding as of the effective time of the Merger will be cancelled and converted into the right to receive 0.445 common units representing limited partnership interests of PAA (&#147;<u>PAA common units</u>&#148;) per PNG common unit. The transaction is expected to result in approximately 14.7 million additional common units being issued by PAA.&#160; In connection with the closing of the Merger, the owners of PAA&#146;s general partner have agreed to reduce their incentive distribution rights under PAA&#146;s agreement of limited partnership by $12 million in each of 2014 and 2015, $10 million in 2016 and $5 million per year thereafter. All of the PNG common units and PNG subordinated units owned by PAA will be unchanged and remain issued and outstanding, representing limited partnership interests of the surviving entity, and no consideration will be delivered in respect thereof. Incentive distribution rights of PNG, which are owned by PNG GP, will also be unchanged and remain outstanding as incentive distribution rights of the surviving entity, and no consideration will be delivered in respect thereof. No fractional PAA common units will be issued in the Merger. Holders of PNG common units, other than PAA, will receive cash in lieu of receiving any fractional PAA common unit to which any holder of PNG common units would otherwise have been entitled in an amount equal to such fractional interest multiplied by the average of the closing price of PAA common units for the ten consecutive NYSE full trading days ending at the closing of the last NYSE full trading day immediately preceding the day the merger closes. The parties anticipate that the Merger will close in the latter half of the fourth quarter of 2013, pending the satisfaction of certain customary conditions thereto, and that the previously announced quarterly distribution of $0.3575 per PNG common unit payable to holders of record of such units on November&nbsp;1, 2013 will be paid on November&nbsp;14, 2013 as scheduled.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">HOUSTON &#151; October&nbsp;22, 2013 &#151; Plains All American Pipeline, L.P. (NYSE: PAA) today announced that it has entered into a definitive agreement and plan of merger (the &#147;Merger Agreement&#148;) with PAA Natural Gas Storage, L.P. (&#147;PNG&#148;) that provides for a merger whereby PNG will become a wholly-owned subsidiary of PAA, through a unit-for-unit exchange (the &#147;Merger&#148;). Under the terms of the Merger Agreement, PNG&#146;s public unitholders will receive 0.445 common units of PAA per PNG common unit surrendered pursuant to the Merger Agreement, plus cash in lieu of any fractional common units of PAA otherwise issuable in the Merger.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The transaction is expected to result in approximately 14.7 million additional common units being issued by PAA.&#160; In connection with the closing of the Merger, the owners of PAA&#146;s general partner have agreed to reduce their incentive distribution rights under PAA&#146;s Agreement of Limited Partnership by $12 million in each of 2014 and 2015, $10 million in 2016 and $5 million per year thereafter.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The terms of the Merger Agreement were approved by the Conflicts Committee of the board of directors of the general partner of PNG (the &#147;Conflicts Committee&#148;), who negotiated the terms on behalf of PNG. The Conflicts Committee is comprised solely of independent directors. In addition, Evercore acted as financial advisor to the Conflicts Committee and delivered a fairness opinion to the Conflicts Committee in connection with the transaction.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The closing of the Merger is subject to the satisfaction of certain conditions, including the approval of the Merger and the Merger Agreement at a special meeting of the unitholders of PNG by the affirmative vote of holders of a majority of the outstanding PNG common units (including PNG common units held by PAA) voting as a separate class and the affirmative vote of holders of a majority of PNG&#146;s outstanding subordinated units voting as a separate class. PAA owns 100% of the membership interests in the general partner of PNG, 100% of the outstanding subordinated units of PNG and approximately 46% of the 61.2 million outstanding common units of PNG. Pursuant to the Merger Agreement, PAA has agreed to vote its common units and subordinated units in favor of the Merger. The parties anticipate that the Merger will close in the latter half of the fourth quarter of 2013, and that the previously announced quarterly distribution</font></p>
