Re:    Grant of Phantom Units

Dear [Name]:

I am pleased to inform you that you have been granted [LTIPs] Phantom Units as of the above date pursuant to the Company’s 2013 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.

1.Subject to the further provisions of this Agreement, your Phantom Units shall vest (become payable in the form of one Common Unit of PAA for each Phantom Unit) as follows:

a.Tranche A, which shall consist of 50% of the total number of Phantom Units covered by this grant letter, shall vest on the August 2026 Distribution Date;

b.Tranche B, which shall consist of 25% of the total number of Phantom Units covered by this grant letter, shall vest on the later of the August 2026 Distribution Date and the first Distribution Date following the date on which the Partnership generates distributable cash flow (“DCF”) per common unit and common unit equivalent on a trailing four quarter basis of at least $2.80; and

c.Tranche C, which shall consist of 25% of the total number of Phantom Units covered by this grant letter, shall vest on the later of the August 2026 Distribution Date and the first Distribution Date following the date on which the Partnership generates DCF per common unit and common unit equivalent on a trailing four quarter basis of at least $3.15.

The DCF performance thresholds described in this paragraph shall apply to any trailing four-quarter period beginning on or after January 1, 2020. Any remaining Phantom Units that have not vested on or before the August 2028 Distribution Date, and any associated DERs (regardless of vesting), shall expire on such date. The DCF per common unit and common unit equivalent amounts referenced in this paragraph are subject to adjustment in the reasonable discretion of the Board based on a recommendation of the CEO to account for significant asset sales, acquisitions or capital transactions.

2.Subject to the further provisions of this Agreement, your DERs shall vest (become payable in cash) as follows: (i) one-fifth of your DERs shall vest upon and effective with the August 2020 Distribution Date; (ii) one-fifth of your DERs shall vest upon and effective with the August 2021 Distribution Date; (iii) one-fifth of your DERs shall vest upon and effective with the August 2022 Distribution Date; (iv) one-fifth of your DERs shall vest upon and effective with the first Distribution Date following the date on which the Partnership generates DCF per common unit and common unit equivalent on a trailing four quarter basis of at least $2.70; and (v) one fifth of your DERs shall vest upon and effective with the first Distribution Date following the date on which the Partnership generates DCF per common unit and common unit equivalent on a trailing four quarter basis of at least $2.90. The DCF performance thresholds described in sections (iv) and (v) of this paragraph shall apply to any trailing four-quarter period beginning on or after January 1, 2020. The DCF per common unit and common unit equivalent amounts referenced in this paragraph are subject to adjustment in the reasonable discretion of the Board based on a recommendation of the CEO to account for significant asset sales, acquisitions or capital transactions.

3.Your DERs shall not accrue payments prior to vesting.

4.The number of Phantom Units subject to this award and any DCF per common unit and common unit equivalent level required for vesting under paragraphs 1 or 2 above shall be proportionately reduced or increased for any split or reverse split, respectively, of the Units, or any event or transaction having a similar effect.

5.Upon vesting of any Phantom Units, an equivalent number of DERs will expire. Any such DERs that are vested prior to, or that would vest as of, the Distribution Date on which the Phantom Units vest, shall be payable on such Distribution Date prior to their expiration.

6.In the event of the termination of your employment with the Company and its Affiliates for any reason (other than in connection with a Change in Status or by reason of your death or “disability,” as defined in paragraph 7 below), all of your then outstanding DERs (regardless of vesting) and Phantom Units 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, the following provisions shall apply: (i) if such termination occurs prior to the second anniversary of the date of this grant letter, 20% of your unvested Phantom Units shall be deemed nonforfeitable on the date of termination, and shall vest on the next following Distribution Date; (ii) if such termination occurs on or after the second anniversary of the date of this grant letter but prior to the third anniversary of the date of this grant letter, 40% of your unvested Phantom Units shall be deemed nonforfeitable on the date of termination, and shall vest on the next following Distribution Date; (iii) if such termination occurs on or after the third anniversary of the date of this grant letter but prior to the fourth anniversary of the date of this grant letter, 60% of your unvested Phantom Units shall be deemed nonforfeitable on the date of termination, and shall vest on the next following Distribution Date; (iv) if such termination occurs on or after the fourth anniversary of the date of this grant letter but prior to the fifth anniversary of the date of this grant letter, 80% of your unvested Phantom Units shall be deemed nonforfeitable on the date of termination, and shall vest on the next following Distribution Date; (v) if such termination occurs on or after the fifth anniversary of the date of this grant letter, 100% of your unvested Phantom Units shall be deemed nonforfeitable on the date of termination, and shall vest on the next following Distribution Date; and (vi) any DERs associated with such unvested, nonforfeitable Phantom Units described in clauses (i)-(v) immediately preceding shall not be forfeited on the date of termination, but shall vest in accordance with paragraph 2 above and if vested shall be payable and shall expire in accordance with paragraph 1 or paragraph 5 above.

7.In the event of the termination of your employment with the Company and its Affiliates by reason of your death or your “disability” (a physical or mental infirmity that impairs your ability substantially to perform your duties for a period of eighteen months or that the Company otherwise determines constitutes a “disability”), the following provisions shall apply: (i) if such termination takes place prior to the second anniversary of the date of this grant letter, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination and (ii) if such termination takes place on or after the second anniversary of the date of this grant, 100% of the unvested Phantom Units covered by paragraph 1(a) above, and any unvested Phantom Units covered by paragraphs 1(b) and 1(c) above with respect to which the Partnership has, as of the date of termination, achieved the applicable DCF vesting criteria for such Phantom Units, shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date (and any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on the date of termination, but shall vest in accordance with paragraph 2 above and if vested shall be payable and shall expire in accordance with paragraph 1 or paragraph 5 above). As soon as administratively practicable after the vesting of any Phantom Units pursuant to this paragraph 7, payment will be made in cash in an amount equal to the Market Value of the number of Phantom Units vesting.

8.In the event of a Change in Status, all of your then outstanding Phantom Units and tandem DERs shall be deemed 100% nonforfeitable on such date, and such Phantom Units shall vest in full upon the next Distribution Date.

9.Upon payment pursuant to a DER, the Company will withhold any taxes due from your compensation as required by law. Upon vesting of a Phantom Unit, the Company will withhold any taxes due from your compensation as required by law, which (in the sole discretion of the Company) may include withholding a number of Common Units otherwise payable to you.

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); (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; and (iv) “Board” means the board of directors of PAGP GP (defined below).

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.

The phrase “Change of Control” means, and shall be deemed to have occurred upon the occurrence of, one or more of the following events:

(“PAGP”) and any affiliate of PAGP that is controlled by PAGP) becomes the beneficial owner, directly or indirectly (in one transaction or a series of related transactions and whether by merger or otherwise), of 50% or more of the membership interest in PAA GP Holdings LLC, a Delaware limited liability company (“PAGP GP”);

(iv)the consummation of a reorganization, merger or consolidation with, or any direct or indirect sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Partnership to, one or more Persons (other than PAGP or any affiliates of PAGP that are controlled by PAGP).

As used in this definition, “Person” shall include any “partnership, limited partnership, syndicate or other group” constituting a “person” within the meaning of such terms pursuant to Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended.
