NON-CASH COMPENSATION PLANS:

We, Sunoco LP and USAC, have issued equity incentive plans for employees, officers and directors, which provide for various types of awards, including options to purchase Common Units, restricted units, phantom units, distribution equivalent rights (“DERs”), common unit appreciation rights, cash restricted units and other non-cash compensation awards. As of December 31, 2020, an aggregate total of 34.3 million ET Common Units remain available to be awarded under our equity incentive plans.

ET Long-Term Incentive Plan

We have granted restricted unit awards to employees that vest over a specified time period, typically a five-year service vesting requirement, with vesting based on continued employment as of each applicable vesting date. Upon vesting, ET Common Units are issued. These unit awards entitle the recipients of the unit awards to receive, with respect to each Common Unit subject to such award that has not either vested or been forfeited, a cash payment equal to each cash distribution per Common Unit made by us on our Common Units promptly following each such distribution by us to our Unitholders. We refer to these rights as “distribution equivalent rights.” Under our equity incentive plans, our non-employee directors each receive grants with a five-year service vesting requirement.

The following table shows the activity of the awards granted to employees and non-employee directors:


	Number of Units	Weighted Average Grant-Date Fair Value Per Unit
Unvested awards as of December 31, 2019	28.0	$	13.89

Awards granted	9.4	6.29
Awards vested	(6.9)	14.78
Awards forfeited	(1.1)	13.85
Unvested awards as of December 31, 2020	29.4	11.26

During the years ended December 31, 2020, 2019, and 2018, the weighted average grant-date fair value per unit award granted was $6.29, $12.51 and $13.00, respectively. The total fair value of awards vested was $51 million, $47 million, and $49 million, respectively, based on the market price of the respective Common Units as of the vesting date. As of

December 31, 2020, a total of 29.4 million unit awards remain unvested, for which ET expects to recognize a total of $193 million in compensation expense over a weighted average period of 2.8 years.

Cash Restricted Units. The Partnership has also granted cash restricted units, which vest through three year of service. A cash restricted unit entitles the award recipient to receive cash equal to the market value of one one ET Common Unit upon vesting. In December 2020, the Partnership granted a total of 7.7 million cash restricted units.

Subsidiary Long-Term Incentive Plans

Each of Sunoco LP and USAC has granted restricted or phantom unit awards (collectively, the “Subsidiary Unit Awards”) to employees and directors that entitle the grantees to receive common units of the respective subsidiary. In some cases, at the discretion of the respective subsidiary’s compensation committee, the grantee may instead receive an amount of cash equivalent to the value of common units upon vesting. Substantially all of the Subsidiary Unit Awards are time-vested grants, which generally vest over a three or five-year period, that entitles the grantees of the unit awards to receive an amount of cash equal to the per unit cash distributions made by the respective subsidiaries during the period the restricted unit is outstanding.

The following table summarizes the activity of the Subsidiary Unit Awards:


	Sunoco LP			USAC
	Number of Units	Weighted Average Grant-Date Fair Value Per Unit		Number of Units	Weighted Average Grant-Date Fair Value Per Unit
