Note 1.   Business Overview and Basis of Financial Statement Presentation

Company Organization and Background

DEP Holdings, LLC (“DEP GP”) is a Delaware limited liability company that was formed on September 29, 2006, to own a 2% general partner interest in Duncan Energy Partners L.P. (“Duncan Energy Partners”). DEP GP is a wholly owned subsidiary of Enterprise Products Operating LLC (“EPO”).  DEP GP’s primary business purpose is to manage the affairs and operations of Duncan Energy Partners. The business purpose of Duncan Energy Partners is to acquire, own and operate a diversified portfolio of midstream energy assets and to support the growth objectives of EPO and other affiliates under common control.   Unless the context requires otherwise, references to “we,” “us,” “our,” or “DEP Holdings” are intended to mean the business and operations of DEP Holdings, LLC and its consolidated subsidiaries, which include Duncan Energy Partners L.P. and its consolidated subsidiaries.  References to “DEP GP” are intended to mean and include DEP Holdings, LLC, individually as the general partner of Duncan Energy Partners L.P., and not on a consolidated basis.

Duncan Energy Partners L.P. (“Duncan Energy Partners”) is a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “DEP.”  Duncan Energy Partners is engaged in the business of (i) natural gas liquids (“NGL”) transportation and fractionation; (ii) the storage of NGL and petrochemical products; (iii) the transportation of petrochemical products (iv) the gathering, transportation and storage of natural gas; and (v) the marketing of NGLs and natural gas.

At March 31, 2009, Duncan Energy Partners was owned 99.3% by its limited partners and 0.7% by its general partner, DEP GP.  At March 31, 2009, EPO owned approximately 74% of Duncan Energy Partner’s limited partner interests and 100% of DEP GP.  DEP Operating Partnership L.P. (“DEP OLP”), a wholly owned subsidiary of Duncan Energy Partners, conducts substantially all of Duncan Energy Partners’ business.  A privately-held affiliate, EPCO, Inc. (“EPCO”), provides all of Duncan Energy Partners’ employees and certain administrative services to the partnership.

Basis of Financial Statement Presentation

Since DEP GP exercises control over Duncan Energy Partners, DEP GP consolidates the financial statements of Duncan Energy Partners.  DEP GP has no independent operations and no material assets outside those of Duncan Energy Partners.

For financial reporting purposes, the assets and liabilities of our majority owned subsidiaries are consolidated with those of our own.   The number of reconciling items between our consolidated balance sheet and that of Duncan Energy Partners are few.

Effective February 1, 2007, Duncan Energy Partners acquired controlling ownership interests in five midstream energy companies (the “DEP I Midstream Businesses”) from EPO in a dropdown transaction.  The DEP I Midstream Businesses consist of (i) Mont Belvieu Caverns, LLC (“Mont Belvieu Caverns”); (ii) Acadian Gas, LLC (“Acadian Gas”); (iii) Enterprise Lou-Tex Propylene Pipeline L.P. (“Lou-Tex Propylene”), including its general partner; (iv) Sabine Propylene Pipeline L.P. (“Sabine Propylene”), including its general partner; and (v) South Texas NGL Pipelines, LLC (“South Texas NGL”).

On December 8, 2008, Duncan Energy Partners entered into a Purchase and Sale Agreement (the “DEP II Purchase Agreement”) with EPO and Enterprise GTM Holdings L.P. (“Enterprise GTM”), a wholly owned subsidiary of EPO.  Pursuant to the DEP II Purchase Agreement, DEP OLP acquired 100% of the membership interests in Enterprise Holding III, LLC (“Enterprise III”) from Enterprise GTM, thereby acquiring a 66% general partner interest in Enterprise GC, L.P. (“Enterprise GC”), a 51% general

NOTES TO UNAUDITED CONDENSED CONSOLIDATED BALANCE SHEET

partner interest in Enterprise Intrastate L.P. (“Enterprise Intrastate”) and a 51% membership interest in Enterprise Texas Pipeline LLC (“Enterprise Texas”).  Collectively, we refer to Enterprise GC, Enterprise Intrastate and Enterprise Texas as the “DEP II Midstream Businesses.”  EPO was the sponsor of this second dropdown transaction.

For additional information regarding the dropdowns of the DEP I and DEP II Midstream Businesses, please read Note 1 of the Notes to Consolidated Balance Sheet for the year ended December 31, 2008, which was included as an exhibit to the Current Report on Form 8-K filed by Duncan Energy Partners on March 12, 2009.

Duncan Energy Partners, DEP GP, DEP OLP, Enterprise Products Partners (including EPO and its consolidated subsidiaries) and EPCO and affiliates are under common control of Mr. Dan L. Duncan, the Group Co-Chairman and controlling shareholder of EPCO.  Prior to the dropdown of controlling ownership interests in the DEP I and DEP II Midstream Businesses to Duncan Energy Partners, EPO owned these businesses and directed their respective activities for all periods presented (to the extent such businesses were in existence during such periods).  Each of the dropdown transactions was accounted for at EPO’s historical costs as a reorganization of entities under common control in a manner similar to a pooling of interests.  On a standalone basis, Duncan Energy Partners did not own any assets prior to February 1, 2007.

References to “Duncan Energy Partners” mean the registrant and its consolidated subsidiaries since February 2007.

Our balance sheet has been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).  All intercompany balances and transactions have been eliminated in consolidation.  Transactions between EPO and us have been identified in our unaudited condensed consolidated balance sheet as transactions between affiliates.

Effective January 1, 2009, we adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) 160, Noncontrolling Interests in Consolidated Financial Statements.  SFAS 160 established accounting and reporting standards for noncontrolling interests, which were previously identified as Parent interest in our financial statements.  This new standard requires, among other things, that (i) noncontrolling interests be presented as a component of equity on our consolidated balance sheet (i.e., elimination of the “mezzanine” presentation previously used for Parent interest); and (ii) elimination of “Parent interest in income of subsidiaries” amounts as a deduction in deriving net income or loss and, as a result, that net income or loss be allocated between the reporting entity’s unitholders and us on one hand and noncontrolling interests on the other.

The unaudited condensed consolidated balance sheet included in this Current Report on Form 8-K reflects the changes required by SFAS 160.

Note 2.  General Accounting Matters

Estimates

Preparing our balance sheet in conformity with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date. Our actual results could differ from these estimates. On an ongoing basis, management reviews its estimates based on currently available information.  Changes in facts and circumstances may result in revised estimates.

Recent Accounting Developments

The following information summarizes recently issued accounting guidance since those reported in our audited consolidated balance sheet for the year ended December 31, 2008, which was included as an

4

DEP HOLDINGS, LLC

NOTES TO UNAUDITED CONDENSED CONSOLIDATED BALANCE SHEET

exhibit to the Current Report on Form 8-K filed by Duncan Energy Partners on March 12, 2009. This guidance will or may affect our future financial statements.

In April 2009, the Financial Accounting Standards Board (“FASB”) issued new guidance in the form of FASB Staff Positions (“FSPs”) in an effort to clarify certain fair value accounting rules.   FSP FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly, establishes a process to determine whether a market is not active and a transaction is not distressed.   FSP FAS 157-4 states that companies should look at several factors and use judgment to ascertain if a formerly active market has become inactive.   When estimating fair value, FSP FAS 157-4 requires companies to place more weight on observable transactions determined to be orderly and less weight on transactions for which there is insufficient information to determine whether the transaction is orderly (entities do not have to incur undue cost and effort in making this determination).   The FASB also issued FSP FAS 107-1 and APB 28-1, Interim Disclosures About Fair Value of Financial Instruments.   This FSP requires that companies provide qualitative and quantitative information about fair value estimates for all financial instruments not measured on the balance sheet at fair value in each interim report.  Previously, this was only an annual requirement.  We will adopt these FSPs effective July 1, 2009.   We do not expect that this new guidance will have a material impact on our balance sheet.

Note 3. Accounting for Equity Awards

We account for equity awards in accordance with SFAS 123(R), Share-Based Payment.  Such awards were not material to our consolidated financial position.  There has been no change in our accounting for equity awards since those reported in our audited consolidated balance sheet, which was included as an exhibit in the Current Report on Form 8-K filed by Duncan Energy Partners on March 12, 2009.

Certain key employees of EPCO participate in long-term incentive compensation plans managed by EPCO.  The compensation expense we record related to unit-based awards is based on an allocation of the total cost of such incentive plans to EPCO.  We record our pro rata share of such costs based on the percentage of time each employee spends on our consolidated business activities, in accordance with the administrative services agreement (the “ASA”).

Note 4.  Derivative Instruments and Hedging Activities

In the course of our normal business operations, we are exposed to certain risks, including changes in interest rates and commodity prices. In order to manage risks associated with certain identifiable and anticipated transactions, we use derivative instruments. Derivatives are financial instruments whose fair value is determined by changes in a specified benchmark such as interest rates or commodity prices. Typical derivative instruments include futures, forward contracts, swaps and other instruments with similar characteristics.  All of our derivatives are used for non-trading activities.

SFAS 133, Accounting for Derivative Instruments and Hedging Activities, requires companies to recognize derivative instruments at fair value as either assets or liabilities on the balance sheet.  While the standard requires that all derivatives be reported at fair value on the balance sheet, changes in fair value of the derivative instruments will be reported in different ways, depending on the nature and effectiveness of the hedging activities to which they are related.  After meeting specified conditions, a qualified derivative may be specifically designated as a total or partial hedge of:

§   Changes in the fair value of a recognized asset or liability, or an unrecognized firm commitment - In a fair value hedge, all gains and losses (of both the derivative instrument and the hedged item) are recognized in income during the period of change.

5

DEP HOLDINGS, LLC

NOTES TO UNAUDITED CONDENSED CONSOLIDATED BALANCE SHEET

§   Variable cash flows of a forecasted transaction - In a cash flow hedge, the effective portion of the hedge is reported in other comprehensive income and is reclassified into earnings when the forecasted transaction affects earnings.

An effective hedge is one in which the change in fair value of a derivative instrument can be expected to offset 80% to 125% of changes in the fair value of a hedged item at inception and throughout the life of the hedging relationship.   The effective portion of a hedge is the amount by which the derivative instrument exactly offsets the change in fair value of the hedged item during the reporting period.  Conversely, ineffectiveness represents the change in the fair value of the derivative instrument that does not exactly offset the change in the fair value of the hedged item. Any ineffectiveness associated with a hedge is recognized in earnings immediately.  Ineffectiveness can be caused by, among other things, changes in the timing of forecasted transactions or a mismatch of terms between the derivative instrument and the hedged item.

On January 1, 2009, we adopted the disclosure requirements of SFAS 161, Disclosures About Derivative Financial Instruments and Hedging Activities.   SFAS 161 requires enhanced qualitative and quantitative disclosure requirements regarding derivative instruments.  This footnote reflects the new disclosure standard.

Interest Rate Derivative Instruments

We utilize interest rate swaps to manage our exposure to changes in the interest rates of certain consolidated debt agreements. This strategy is a component in controlling our cost of capital associated with such borrowings.

The following table summarizes our interest rate derivative instruments outstanding at March 31, 2009, all of which were designated as hedging instruments under SFAS 133:

	Number and Type of	Notional	Length of	Rate	Accounting
Hedged Transaction	Derivative Employed	Amount	Hedge	Swap	Treatment
Revolving Credit Facility:
Variable-interest rate borrowings	3 floating-to-fixed swaps	$175.0	9/07 to 9/10	1.2% to 4.6%	Cash flow

Commodity Derivative Instruments

The price of natural gas is subject to fluctuations in response to changes in supply, demand, general market uncertainty and a variety of additional factors that are beyond our control. In order to manage the price risk associated with such products, Acadian Gas enters into commodity derivative instruments such as forwards, basis swaps and futures contracts. The following table summarizes our commodity derivative instruments outstanding at March 31, 2009:

	Volume (1)		Accounting
Derivative Purpose	Current	Long-Term	Treatment
Derivatives not designated as hedging instruments under SFAS 133:
Acadian Gas:
Natural gas risk management activities (2)	1.8 Bcf	n/a	Mark-to-market
(1)Volume for derivatives not designated as hedging instruments reflect the absolute value of derivative notional volumes. (2)Reflects the use of derivative instruments to manage risks associated with natural gas pipeline, processing and storage assets.

At March 31, 2009, none of Acadian Gas’ derivative instruments met the hedge accounting requirements of SFAS 133 and are accounted for as economic hedges using mark-to-market accounting.

Acadian Gas’ hedging strategy is to reduce the variability of its future earnings and cash flows resulting from changes in natural gas prices.  Acadian Gas enters into a limited number of offsetting mark-

NOTES TO UNAUDITED CONDENSED CONSOLIDATED BALANCE SHEET

to-market derivatives that effectively fix the price of natural gas for certain of its customers. Acadian Gas may also enter into a small number of cash flow hedges in connection with its purchase of natural gas held-for-sale to third parties.

       Credit-Risk Related Contingent Features in Derivative Instruments

A limited number of our commodity derivative instruments include provisions related to credit ratings and/or adequate assurance clauses.  A credit rating provision provides for a counterparty to demand immediate full or partial payment to cover a net liability position upon the loss of a stipulated credit rating. An adequate assurance clause provides for a counterparty to demand immediate full or partial payment to cover a net liability position should reasonable grounds for insecurity arise with respect to contractual performance by either party.  At March 31, 2009, none of our derivative instruments were in a net liability position nor were any subject to these contingent features.  The potential for derivatives with contingent features to enter a net liability position may change in the future as positions and prices fluctuate. 

The following table provides a balance sheet overview of our derivative assets and liabilities:

Asset Derivatives		Liability Derivatives

SFAS 157 - Fair Value Measurements

SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date.  The following table sets forth, by level within the fair value hierarchy, our financial assets and liabilities measured on a recurring basis at March 31, 2009.  These financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.  Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of the fair value assets and liabilities and their placement within the fair value hierarchy levels.

(2)Forward sales inventory consists of identified NGL and natural gas volumes dedicated to the fulfillment of forward sales contracts.

Due to fluctuating market prices for natural gas, we record non-cash, lower of average cost or market (“LCM”) adjustments in connection with our available-for-sale inventory.   Our LCM adjustments were immaterial for the three months ended March 31, 2009.

Note 12.  Related Party Transactions

The following information summarizes our business relationships and transactions with related parties at March 31, 2009.  We believe that the terms and provisions of our related party agreements are fair to us; however, such agreements and transactions may not be as favorable to us as we could have obtained from unaffiliated third parties.

Duncan.  Mr. Duncan is Chairman of our general partner and is the Group Co-Chairman and the controlling shareholder of EPCO.  Our general partner is wholly owned by EPO and EPCO provides all of our employees, including our executive officers.

Significant Relationships and Agreements with EPO

At March 31, 2009, EPO owned approximately 74% of the limited partner interests of Duncan Energy Partners and 100% of us.  EPO was the sponsor of the DEP I and DEP II dropdown transactions and owns varying interests (as Parent) in the DEP I and DEP II Midstream Businesses.  For a description of EPO’s noncontrolling interest in the income and net assets of the DEP I and DEP II Midstream Businesses, see Note 10.  EPO may contribute or sell other equity interests or assets to us; however, EPO has no obligations or commitment to make such contributions or sales to us, nor do we have any obligation or commitments to accept such contributions or make such purchases.

Omnibus Agreement.   On December 8, 2008, we entered into an amended and restated Omnibus Agreement (the “Omnibus Agreement”) with EPO.  The provisions of the Omnibus Agreement have not changed since reported in Note 13 of the Notes to Consolidated Balance Sheet for the year ended December 31, 2008, which was included as an exhibit to the Current Report on Form 8-K filed by Duncan Energy Partners on March 12, 2009.

EPO indemnified us for certain environmental liabilities, tax liabilities and right-of-way defects associated with the assets it contributed to us in connection with the DEP I and DEP II dropdown transactions.  These indemnifications terminate on February 5, 2010.  We made no claims to EPO during the three months ended March 31, 2009.

Mont Belvieu Caverns’ LLC Agreement.The Mont Belvieu Caverns’ Limited Liability Company Agreement (the “Caverns LLC Agreement”) states that if Duncan Energy Partners elects to not participate in certain projects of Mont Belvieu Caverns, then EPO is responsible for funding 100% of such projects.  To the extent such non-participated projects generate identifiable incremental cash flows for Mont Belvieu Caverns in the future, the earnings and cash flows of Mont Belvieu Caverns will be adjusted to allocate such incremental amounts to EPO, by special allocation or otherwise. Under the terms of the Caverns LLC Agreement, Duncan Energy Partners may elect to acquire a 66% share of these projects from EPO within 90 days of such projects being placed in service.  The constructed assets will be the property of Mont Belvieu Caverns.

The Caverns LLC Agreement also requires the allocation to EPO of operational measurement gains and losses.  Operational measurement gains and losses are created when product is moved between storage wells and are attributable to pipeline and well connection measurement variances.

In November 2008, the Caverns LLC Agreement was amended to provide that EPO would prospectively receive a special allocation (through noncontrolling interest) of 100% of the depreciation related to projects that it has fully funded.

Company and Limited Partnership Agreements – DEP II Midstream Businesses.   On December 8, 2008, the DEP II Midstream Businesses amended and restated their governing documents in connection with the DEP II dropdown transaction.  Collectively, these amendments include, but are not limited to, (i) the payment of cash distributions in accordance with an overall “waterfall” approach, (ii) the funding of operating cash flow deficits and (iii) the election by either owner to fund cash calls associated with expansion capital projects.  See Note 13 of the Notes to Consolidated Balance Sheet for the year ended December 31, 2008, which was included as an exhibit to the Current Report on Form 8-K filed by Duncan Energy Partners on March 12, 2009.

Enterprise III does not participate in expansion project spending with respect to the DEP II Midstream Businesses, although it may elect to invest in existing or future expansion projects at a later date. As a result, Enterprise GTM has funded 100% of such growth capital spending and its Distribution Base has increased from $473.4 million at December 31, 2008 to $586.8 million at March 31, 2009.  The Enterprise III Distribution Base was unchanged at $730.0 million at March 31, 2009.

Relationship with Evangeline

Evangeline has entered into a natural gas purchase contract with Acadian Gas that contains annual purchase provisions. The pricing terms of the purchase agreement are based on a monthly weighted-average market price of natural gas (subject to certain market index price ceilings and incentive margins) plus a predetermined margin.

The Partnership has furnished letters of credit on behalf of Evangeline’s debt service requirements.  The outstanding letters of credit totaled $1.0 million, at March 31, 2009.

Relationship with Energy Transfer Equity

In May 2007, Enterprise GP Holdings acquired equity method investments in, and therefore is a related party to, Energy Transfer Equity and its general partner.  As a result of the common control of Enterprise GP Holdings and us, Energy Transfer Equity became a related party to us.

Relationship with TEPPCO

Beginning in 2008, Mont Belvieu Caverns commenced providing NGL and petrochemical storage services to TEPPCO.  For the period January 2007 through March 2008, we leased from TEPPCO an 11-mile pipeline that was part of our South Texas NGL System.  We discontinued this lease during the first quarter of 2008 when we completed the construction of a parallel pipeline.

Note 13.  Commitments and Contingencies

Litigation

On occasion, we are named as a defendant in litigation relating to our normal business operations, including regulatory and environmental matters.  Although we insure against various business risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to indemnify us against liabilities arising from future legal proceedings as a result of our ordinary business activities.  We are not aware of any litigation, pending or threatened, that may have a significant adverse effect on our financial position or results of operations.

Redelivery Commitments

We transport and store natural gas and NGLs and store petrochemical products for third parties under various contracts.  These volumes are (i) accrued as product payables on our Unaudited Condensed Consolidated Balance Sheet, (ii) in transit for delivery to our customers or (iii) held at our storage facilities for redelivery to our customers.  We are insured against any physical loss of such volumes due to catastrophic events.  Under the terms of our NGL and petrochemical product storage agreements, we are generally required to redeliver volumes to the owner on demand.  At March 31, 2009, NGL and petrochemical products aggregating 20.8 million barrels, were due to be redelivered to their owners along with 5,116 BBtus of natural gas.
