Dear «Salutation»:

I am pleased to inform you that you have been granted «Amount» Phantom Units as of the above date pursuant to the Company’s «LTIP_Plan» Long-Term Incentive Plan (the “Plan”). In addition, in tandem with each Phantom Unit you have been granted a distribution equivalent right (a “DER”). A DER represents the right to receive a cash payment equivalent to the amount, if any, paid in cash distributions on one Common Unit of Plains All American Pipeline, L.P. (“PAA” or the “Partnership”) to the holder of such Common Unit. The terms and conditions of this grant are as set forth below.

Phantom Units and DERs shall automatically be forfeited as of the date of termination; provided, however, that if the Company or its Affiliates terminate your employment other than as a result of a Termination for Cause, (i) all of your then outstanding Phantom Units shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date, and (ii) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on the date of termination, but shall be payable and shall expire on the next following Distribution Date.

As used herein, (i) the “Company” refers to Plains All American GP LLC; (ii) “Distribution Date” means the day in February, May, August or November in any year (as context dictates) that is 45 days after the end of the most recently completed calendar quarter (or, if not a business day, the closest previous business day); and (iii) “Market Value” means the average of the closing sales prices for a Common Unit on the New York Stock Exchange for the five trading days preceding the then most recent “ex dividend” date for payment of a distribution by the Partnership.

The phrase “Change in Status” means (A) the termination of your employment by the Company other than a Termination for Cause, within two and a half months prior to or one year following a Change of Control (the “Protected Period”), (B) the termination of your employment by you due to the occurrence during the Protected Period, without your written consent, of (i) any material diminution in your authority, duties or responsibilities, (ii) any material reduction in your base salary, or (iii) any other action or inaction that constitutes a material breach of this Agreement by the Company, or (C) the termination of your employment by you as a result of your retirement on terms and timing that are approved by the CEO. A termination by you pursuant to (B) above shall not be a Change in Status unless (1) you provide written notice to the Company of the condition in (B)(i), (ii) or (iii) that would constitute a Change in Status within 90 days of the initial existence of the condition, and (2) the Company fails to remedy the condition within the 30-day period following such notice.

(“PAGP”) ceases to retain direct or indirect control of the general partner of the Partnership; (ii) PAGP ceases to beneficially own, directly or indirectly, more than 50% of the membership interest in the Company; (iii) any direct or indirect sale, lease, exchange or other transfer (in one transaction or a series of related transactions and whether by merger or otherwise) of all or substantially all of the assets of the Partnership, PAGP or the Company to one or more Persons who are not affiliates of PAGP (“third party or parties”), other than a transaction in which the Owner Affiliates (as defined below) continue to beneficially own, directly or indirectly, more than 50% of the issued and outstanding voting securities of such third party or parties immediately following such transaction; (iv) (x) a “person” or “group” (as such terms are defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) other than the Owner Affiliates becomes the “beneficial owner” directly or indirectly of 25% or more of the member interest in PAA GP Holdings LLC, a Delaware limited liability company and the general partner of PAGP (“PAGP GP”), and (y) the member interest beneficially owned by such “person” or “group” exceeds the aggregate member interest in PAGP GP beneficially owned, directly or indirectly, by the Owner Affiliates; (v) any Person (other than PAGP, the Partnership or their respective affiliates), including any partnership, limited partnership, syndicate or other “person” or “group,” becomes the beneficial owner, directly or indirectly, of 50% or more of the membership interest in the Company or 50% or more of the outstanding limited partnership interests of PAGP; or (vi) any Person (other than PAGP or its wholly owned subsidiaries), including any partnership, limited partnership, syndicate or other “person” or “group,” becomes the beneficial owner, directly or indirectly, of 50% or more of the membership interest in PAGP GP.

Terms used herein that are not defined herein shall have the meanings set forth in the Plan or, if not defined in the Plan, in the Seventh Amended and Restated Agreement of Limited Partnership of Plains All American Pipeline, L.P. (the “Partnership Agreement”).

This award is intended to either (i) qualify as a “short-term deferral” under Section 409A of the Internal Revenue Code of 1986, as amended, or (ii) comply with the provisions of Section 409A. If it is determined that any payments or benefits to be made or provided under this Agreement do not comply with Section 409A, the parties agree to amend this Agreement or take such other actions as reasonably necessary or appropriate to comply with Section 409A while preserving the economic agreement of the parties.
