(a) The Partnership has disclosed in this press release Adjusted EBITDA and Distributable Cash Flow, which are non-GAAP financial measures. Management believes Adjusted EBITDA and Distributable Cash Flow provide useful information to investors as measure of comparison with peer companies, including companies that may have different financing and capital structures. The presentation of Adjusted EBITDA and Distributable Cash Flow also allows investors to view our performance in a manner similar to the methods used by management and provides additional insight into our operating results.

	There are material limitations to using measures such as Adjusted EBITDA and Distributable Cash Flow, including the difficulty associated with using either as the sole measure to compare the results of one company to another, and the inability to analyze certain significant items that directly affect a company’s net income or loss or cash flows. In addition, our calculations of Adjusted EBITDA and Distributable Cash Flow may not be consistent with similarly titled measures of other companies and should be viewed in conjunction with measurements that are computed in accordance with GAAP, such as gross margin, operating income, net income, and cash flow from operating activities.
	Definition of Adjusted EBITDA
	The Partnership’s definition of Adjusted EBITDA was revised as discussed in note (b) below. The Partnership defines Adjusted EBITDA as total partnership earnings before interest, taxes, depreciation, amortization and other non-cash items, such as non-cash compensation expense, gains and losses on disposals of assets, the allowance for equity funds used during construction, unrealized gains and losses on commodity risk management activities, non-cash impairment charges, and other non-operating income or expense items. Unrealized gains and losses on commodity risk management activities includes unrealized gains and losses on commodity derivatives and inventory fair value adjustments (excluding lower of cost or market adjustments). Adjusted EBITDA reflects amounts for less than wholly owned subsidiaries and unconsolidated affiliates based on the Partnership’s proportionate ownership.
	Adjusted EBITDA is used by management to determine our operating performance and, along with other financial and volumetric data, as internal measures for setting annual operating budgets, assessing financial performance of our numerous business locations, as a measure for evaluating targeted businesses for acquisition and as a measurement component of incentive compensation.
	Definition of Distributable Cash Flow
	The Partnership defines Distributable Cash Flow as net income, adjusted for certain non-cash items, less maintenance capital expenditures. Non-cash items include depreciation and amortization, deferred income taxes, non-cash compensation expense, gains and losses on disposals of assets, the allowance for equity funds used during construction, unrealized gains and losses on commodity risk management activities, and non-cash impairment charges. Unrealized gains and losses on commodity risk management activities includes unrealized gains and losses on commodity derivatives and inventory fair value adjustments (excluding lower of cost or market adjustments). Distributable Cash Flow reflects amounts for less than wholly owned subsidiaries based on the Partnership’s proportionate ownership and also reflects earnings from unconsolidated affiliates on a cash basis.
	Distributable Cash Flow is used by management to evaluate our overall performance. Our partnership agreement requires us to distribute all available cash, and Distributable Cash Flow is calculated to evaluate our ability to fund distributions through cash generated by our operations.
(b)	The Partnership has presented Adjusted EBITDA and Distributable Cash Flow in previous communications; however, the Partnership changed its definition for these non-GAAP measures in the quarter ended September 30, 2010 to remove lower of cost or market adjustments and the subsequent gross margin impact of such previously recognized inventory adjustments. These amounts had previously been included in unrealized gains and losses on commodity risk management activities, which now reflects unrealized gains and losses on non-hedged derivatives, fair value hedged derivatives and inventory, and the ineffective portion of cash flow hedges. The Partnership believes that with this change, Adjusted EBITDA and Distributable Cash Flow more accurately reflect the Partnership’s operating performance and therefore are more useful measures. This change has been applied retroactively to all periods presented. See “Non-GAAP Measures” available on the Partnership’s website atwww.energytransfer.com for the reconciliation of net income to Adjusted EBITDA for prior periods (beginning with the fiscal year ended August 31, 2005) reflecting the changes described above.

Summary Analysis of Results by Segment
(tabular dollar amounts in thousands)

The reportable segment data included in the tables above and the analysis that follows is presented on a comparable basis to prior periods, except that, following Lone Star’s acquisition of LDH Energy Asset Holdings LLC (“LDH”) on May 2, 2011, (i) our midstream segment now includes Lone Star’s 20% interest in Sea Robin and (ii) we have added a NGL transportation and services segment, which includes all of Lone Star’s NGL transportation, storage and fractionation services.

Intrastate Transportation and Storage

Gross Margin.The components of our intrastate transportation and storage segment gross margin were as follows:

	Three Months Ended June 30,							Six Months Ended June 30,
	2011		2010		Change			2011		2010		Change
Transportation fees	$	157,672	$	154,754	$	2,918		$	300,338	$	295,552	$	4,786
Natural gas sales and other		18,390		15,950		2,440			63,589		55,960		7,629
Retained fuel revenues		36,680		37,385		(705	)		71,662		73,087		(1,425	)
Storage margin, including fees		19,182		11,613		7,569			35,464		20,089		15,375
Total gross margin	$	231,924	$	219,702	$	12,222		$	471,053	$	444,688	$	26,365

Intrastate transportation and storage gross margin changes were primarily due to the following factors:

• Transportation fees increased during the three months ended June 30, 2011 primarily due to an increase in demand fees offset by a decrease in fees recognized as a result of lower interruptible transportation volumes. Transportation fees increased for the six months ended June 30, 2011 primarily due to increases in transportation volumes and demand fees.

• Margin from the sales of natural gas and other activities increased for the three and six months ended June 30, 2011 primarily due to an increase from sales of NGLs offset by a decrease due to lower margins from system optimization activities.

Storage margin was comprised of the following:

	Three Months Ended June 30,									Six Months Ended June 30,
	2011			2010			Change			2011			2010			Change
Withdrawals from storage natural gas inventory (MMBtu)		647,373			871,203			(223,830	)		15,772,126			27,887,990			(12,115,864	)
Margin on physical sales	$	179		$	1,274		$	(1,095	)	$	10,691		$	65,652		$	(54,961	)
Fair value adjustments		3,309			6,301			(2,992	)		4,831			(62,254	)		67,085
Settlements of financial derivatives		(5,199	)		1,570			(6,769	)		571			(8,929	)		9,500
Unrealized gains (losses) on derivatives		12,750			(7,824	)		20,574			1,793			5,294			(3,501	)
Net impact of natural gas inventory transactions		11,039			1,321			9,718			17,886			(237	)		18,123
Revenues from fee-based storage		8,218			10,328			(2,110	)		17,819			21,627			(3,808	)
Other costs		(75	)		(36	)		(39	)		(241	)		(1,301	)		1,060
Total storage margin	$	19,182		$	11,613		$	7,569		$	35,464		$	20,089		$	15,375

For the three months ended June 30, 2011, storage margin increased primarily due to holding more inventory in our storage facility than was subject to the mark-to-market impact of the spread between the spot price and the forward prices narrowing during the period. For the six months ended June 30, 2011, storage margin increased primarily due to favorable changes in the spread between the spot price of natural gas compared to the forward price.

Operating Expenses.Intrastate transportation and storage operating expenses increased for the three months ended June 30, 2011 compared to the same period in the prior year primarily due to an increase in natural gas consumed for compression and an increase in ad valorem taxes. For the six months ended June 30, 2011 operating expenses increased primarily due to an increase in natural gas consumed for compression and an increase in employee related costs.

Depreciation and Amortization.Intrastate transportation and storage depreciation and amortization expense increased for the three and six months ended June 30, 2011 compared to the same periods in the prior year primarily due to the completion of pipeline projects in connection with the continued expansion of our pipeline system.

Selling, General and Administrative.Intrastate transportation and storage selling, general and administrative expenses increased for the three and six months ended June 30, 2011 compared to the same periods in the prior year as a result of an increase in allocated overhead expenses.

Interstate Transportation

Revenues.The increase in interstate transportation revenues for the three and six month periods ended June 30, 2011 compared to the same prior periods in the prior year was primarily due to increased transportation fees associated with the Tiger pipeline which was placed in service in December 2010. The increase was slightly offset by decreased transportation fees from the Transwestern pipeline as a result of lower transportation volumes.

Operating Expenses.Interstate transportation operating expenses increased during the three and six months ended June 30, 2011 compared to the same periods in prior year principally due to incremental operating expenses incurred on the Tiger pipeline which was placed in service in December 2010.

Depreciation and Amortization.Interstate transportation depreciation and amortization expense increased during the three and six months ended June 30, 2011 compared to the same periods in prior year primarily due to incremental depreciation associated with the Tiger pipeline which was placed in service in December 2010.

Selling, General and Administrative.Interstate transportation selling, general and administrative expenses increased during the three and six months ended June 30, 2011 compared to the same periods in the prior year primarily due to increased allocated and employee-related expenses related to the Tiger Pipeline which was placed in service in December 2010.

Midstream

Gross Margin.The components of our midstream segment gross margin were as follows:

	Three Months Ended June 30,								Six Months Ended June 30,
	2011			2010			Change		2011			2010			Change
Gathering and processing fee-based revenues	$	65,989		$	55,583		$	10,406	$	125,596		$	109,878		$	15,718
Non fee-based contracts and processing		65,427			50,226			15,201		111,797			97,496			14,301
Other		(3,487	)		(10,579	)		7,092		(6,551	)		(15,165	)		8,614
Total gross margin	$	127,929		$	95,230		$	32,699	$	230,842		$	192,209		$	38,633

Midstream gross margin increased for the three and six months ended June 30, 2011 compared to the same periods in prior year due to the following:

• An increase in fee-based revenues due to increased gathering and processing volumes on our North Texas system and additional volumes due to recent acquisitions and other growth capital expenditures located in Louisiana.

• Non fee-based contracts and processing margins increased primarily due to favorable NGL prices. In addition, our recently acquired interest in the Sea Robin processing plant (part of the Lone Star joint venture) provided additional margin compared with the same periods in the prior year.

• The increase in other midstream gross margin primarily reflects the impacts from favorable NGL prices on activities where third party processing capacity is utilized.

Operating Expenses.For the three and six months ended June 30, 2011 compared to the same periods in the prior year, operating expenses increased primarily as a result of increases in maintenance and operating costs, ad valorem taxes, professional fees and employee related costs.

Depreciation and Amortization.For the three and six months ended June 30, 2011 compared to the same periods in the prior year, depreciation and amortization expense increased primarily due to incremental depreciation from the continued expansion of our Louisiana and South Texas assets.

Selling, General and Administrative.For the three and six months ended June 30, 2011 compared to the same periods in the prior year, selling, general and administrative expenses increased primarily as a result of an increase in professional fees.

NGL Transportation and Services

Gross Margin.The components of our NGL transportation and services segment gross margin were as follows:

	Three Months Ended June 30,								Six Months Ended June 30,
	2011			2010		Change			2011			2010		Change
Storage revenues	$	23,414		$	—		23,414		$	23,414		$	—	$	23,414
Transportation revenues		7,051			—		7,051			7,051			—		7,051
Processing and fractionation revenues		15,874			—		15,874			15,874			—		15,874
Other revenues		(771	)		—		(771	)		(771	)		—		(771	)
Total gross margin	$	45,568		$	—	$	45,568		$	45,568		$	—	$	45,568

We own a 70% controlling interest in Lone Star, which acquired all of the membership interests in LDH on May 2, 2011 and is primarily engaged in NGL transportation, storage and fractionation. Results reflected above represent 100% of Lone Star from May 2, 2011 to June 30, 2011.

Retail Propane and Other Retail Propane Related

Gross Margin.Gross margin decreased during the six months ended June 30, 2011 compared to the same period in the prior year primarily due to a decrease in sales volumes resulting from weather patterns. The decrease in volumes was partially offset by a favorable impact from mark-to-market adjustments of financial instruments in our commodity price risk management activities and an increase in other retail propane-related gross profit.

Operating Expenses. Operating expenses were lower for the six months ended June 30, 2011 compared to the same period in the prior year primarily due to decreases in performance-based bonus accruals and other general operating expenses.
