ITEM 1.01 Entry into a Material Definitive Agreement.
     Underwriting Agreement
     On April 29, 2010, PAA Natural Gas Storage, L.P. (the “Partnership”) entered into an Underwriting Agreement (the “Underwriting Agreement”), by and among the Partnership, PNGS GP LLC (the “General Partner”), Plains All American Pipeline, L.P. (“PAA,” and together with the Partnership and General Partner, the “Partnership Parties”) and Barclays Capital Inc., UBS Securities LLC, Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein (the “Underwriters”), providing for the offer and sale by the Partnership (the “Offering”), and purchase by the Underwriters, of 11,720,000 common units representing limited partner interests in the Partnership (“Common Units”) at a price to the public of $21.50 per Common Unit ($20.18 per Common Unit, net of underwriting discounts). Pursuant to the Underwriting Agreement, the Partnership also granted the Underwriters an over-allotment option for a period of 30 days (the “Over-Allotment Option”) to purchase up to an additional 1,758,000 Common Units (the “Option Units”) to cover over-allotments, if any, on the same terms. On April 30, 2010, the Underwriters exercised the Over-Allotment Option in full. The material terms of the Offering are described in the prospectus, dated April 29, 2010 (the “Prospectus”), filed by the Partnership with the United States Securities and Exchange Commission (the “Commission”) on May 3, 2010 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is registered with the Commission pursuant to a Registration Statement on Form S-1, as amended (File No. 333-164492), initially filed by the Partnership on January 25, 2010 and pursuant to a Registration Statement on Form S-1 filed pursuant to Rule 462(b) of the Securities Act (File No. 333-166398), filed by the Partnership on April 29, 2010.
          The Underwriting Agreement contains customary representations, warranties and agreements of the Partnership Parties, and customary conditions to closing, obligations of the parties and termination provisions. The Partnership Parties have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments the Underwriters may be required to make because of any of those liabilities.
     The Offering of the Common Units and the sale of the Option Units pursuant to the exercise of the Over-Allotment Option are expected to close on May 5, 2010. The Partnership will receive proceeds (net of underwriting discounts and commissions but before deducting offering expenses) from the Offering of approximately $272 million. As described in the Prospectus, the Partnership will use the net proceeds of the sale of the Common Units to repay intercompany indebtedness owed to PAA. The Partnership will use the net proceeds of the sale of the Option Units to reimburse PAA for capital expenditures it incurred with respect to assets that PAA contributed to the Partnership.
     As more fully described under the caption “Underwriting” in the Prospectus, certain of the Underwriters have in the past provided and may from time to time in the future provide commercial banking, investment banking and advisory services in the ordinary course of their business for the Partnership, PAA and their respective affiliates for which they have received and in the future will be entitled to receive, customary fees and reimbursement of expenses.
