% Fixed/ Floating Rate Junior Subordinated Notes due 2066

Guaranteed to the extent described in this prospectus supplement by

Enterprise Products Partners L.P.

       The      % Fixed/ Floating Rate Junior Subordinated Notes due 2066, which we refer to as “Long-Term Subordinated Notes” or “LoTS^sm,” issued by Enterprise Products Operating L.P. will bear interest from the date they are issued to                , 2016, at the annual rate of      % of their principal amount, payable semi-annually in arrears on                     and                     of each year, and thereafter will bear interest at an annual rate equal to the 3-month LIBOR Rate plus      %, reset quarterly, payable quarterly in arrears on                     ,                     ,                     and                     of each year beginning                     , 2016. The LoTS^sm will mature on                     , 2066.

       We may elect to defer interest payments on the LoTS^sm on one or more occasions for up to ten consecutive years as described in this prospectus supplement. Deferred interest will accumulate additional interest at a rate equal to the interest rate then applicable to the LoTS^sm, to the extent permitted by law. Enterprise Products Partners L.P. will guarantee, on a junior subordinated basis, payment of the principal of, premium, if any, and interest on the LoTS^sm.

       We may redeem the LoTS^sm in whole or in part on or after                     , 2016 at their principal amount plus accrued and unpaid interest. We may redeem the LoTS^sm in whole or in part at any time prior to                     , 2016 upon payment of a “make-whole premium,” as described in this prospectus supplement.

       Investing in the LoTS^sm involves certain risks. See “Risk Factors” beginning on page S-13 of this prospectus supplement and on page 3 of the accompanying prospectus.

       Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

       The underwriters expect to deliver the LoTS^sm in book entry form only, through the facilities of The Depository Trust Company, against payment on July      , 2006.

Issuer		Enterprise Products Operating L.P.
Securities Offered		$300,000,000 aggregate principal amount of our      % Fixed/ Floating Rate Junior Subordinated Notes due 2066, which we refer to as the “Long-Term Subordinated Notes” or “LoTSsm.”
Guarantor		Enterprise Products Partners L.P.
Interest Rate		The LoTSsm will bear interest from the date of issuance to                     , 2016, which we refer to as the “Fixed Rate Period,” at an annual rate of      %, payable semi-annually in arrears on                     and                     of each year, commencing                     , 2007, and thereafter, which we refer to as the “Floating Rate Period,” at an annual rate equal to the 3-month LIBOR Rate (as defined in “Description of the LoTSsm — Determining the Floating Rate”) for the related interest period plus      %, payable quarterly in arrears on                     ,                     ,                     and                     of each year, commencing                     , 2016, unless payment is deferred as described below.
		For a more complete description of interest payable on the LoTSsm, see “Description of the LoTSsm — Interest Rate and Interest Payment Dates” and “Description of the LoTSsm — Determining the Floating Rate.”
Optional Deferral		We may elect to defer payment of all or part of the current and accrued interest otherwise due on the LoTSsm provided that:
		• we may not optionally defer interest payments once we have failed to pay interest otherwise due for a period of ten consecutive years for any reason; and
		• we may not optionally defer interest payments on or after the maturity date of, or redemption date for, the LoTSsm.
		Deferred interest not paid on an interest payment date will bear interest from that interest payment date until paid at the then prevailing interest rate on the LoTSsm compounded semi-annually during the Fixed Rate Period and quarterly during the Floating Rate Period, as described under “Description of the LoTSsm — Interest Rate and Interest Payment Dates.” We refer to such deferred interest, the interest accrued thereon and any accrued and unpaid interest on any interest payment date during a deferral period collectively as “Deferred Interest,” and we refer to a period during which we have elected to defer payment of interest on the LoTSsm as an “Optional Deferral Period.” Once we pay all Deferred Interest resulting from our optional deferral, such Optional Deferral Period will end and we may later defer interest again for a new Optional Deferral Period, subject to the same limitations described above.
Distribution Stopper		Unless:
		• all Deferred Interest on the LoTSsm has been paid in full as of the most recent interest payment date;
		• no event of default has occurred and is continuing; and

		• Enterprise Parent is not in default of its obligations under its guarantee of payments on the LoTSsm,
		then, subject to certain exceptions:
		• we and Enterprise Parent will not declare or make any distributions with respect to, or redeem, purchase or make a liquidation payment with respect to, any of our respective equity securities;
		• we and Enterprise Parent will not and will cause our respective majority-owned subsidiaries not to make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any of our debt securities (including securities similar to the LoTSsm) that contractually rank equally with or junior to the LoTSsm; and
		• we and Enterprise Parent will not and will cause our respective majority-owned subsidiaries not to make any guarantee payments with respect to the securities described in the previous bullet point.
Guarantee		Enterprise Parent will fully and unconditionally guarantee (as described under “Description of the LoTSsm — Parent Guarantee”) the full and prompt payment of principal of, premium, if any, and interest on the LoTSsm, when and as the same become due and payable (subject to our right to defer interest as set forth under “Description of the LoTSsm — Optional Deferral”), whether at stated maturity, upon redemption, by declaration of acceleration or otherwise. The guarantee will be unsecured and subordinated to the senior indebtedness of Enterprise Parent.
Ranking of the LoTSsm		Our payment obligations under the LoTSsm will be unsecured and will, to the extent provided in the indenture, be subordinated to the prior payment in full of all of our present and future indebtedness for borrowed money, indebtedness evidenced by securities, bonds, notes and debentures, obligations under guarantees, direct credit substitutes, hedge and derivative products, capitalized lease obligations, letters of credit, cash management arrangements and other senior indebtedness. However, the LoTSsm will rank equally with our trade accounts payable and certain other liabilities arising in the ordinary course of our business, any of our indebtedness which by its terms is expressly made equal in rank with the LoTSsm and indebtedness owed by us to our majority-owned subsidiaries.
		The LoTSsm will rank senior in right of payment to all of our present and future equity securities.
		The indenture under which the LoTSsm will be issued does not limit our ability to incur additional debt, including debt that ranks senior in priority of payment to or pari passu with the LoTSsm.
		We conduct a significant amount of our operations through our subsidiaries and unconsolidated affiliates, and a significant amount of our assets include our ownership interests in such

		entities. Holders of the LoTSsm will have a junior position to claims of creditors of our subsidiaries and unconsolidated affiliates, including trade creditors, debt holders, secured creditors, taxing authorities and guarantee holders.
Optional Redemption		We may redeem the LoTSsm before their maturity, subject to the Replacement Capital Covenant discussed below:
		• in whole or in part, on one or more occasions at any time on or after                     , 2016 at 100% of their principal amount plus accrued and unpaid interest; or
		• in whole or in part at any time prior to                     , 2016 upon payment of the Make-Whole Redemption Price (as defined below).
		The “Make-Whole Redemption Price” will be equal to (1) all accrued and unpaid interest to but not including the redemption date plus (2) the greater of:
		• 100% of the principal amount of the LoTSsm being redeemed, and
		• as determined by the Independent Investment Banker (as defined in “Description of the LoTSsm — Redemption — Early Redemption”), the sum of the present values of remaining scheduled payments of principal and interest on the LoTSsm being redeemed from the redemption date to                     , 2016, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield (as defined in “Description of the LoTSsm — Redemption — Early Redemption”) plus      %.
Replacement Capital Covenant		Around the time of initial issuance of the LoTSsm, we will enter into a Replacement Capital Covenant (as defined in “Certain Terms of the Replacement Capital Covenant”) in which we will covenant for the benefit of holders of a designated series of our long-term indebtedness that ranks senior to the LoTSsm that we will not redeem or repurchase the LoTSsm on or before                     , 2036, unless, subject to certain limitations, during the 180 days prior to the date of that redemption or repurchase we, Enterprise Parent or one of our or its subsidiaries has received a specified amount of proceeds from the sale of qualifying securities that have characteristics that are the same as, or more equity-like than, the applicable characteristics of the LoTSsm. The Replacement Capital Covenant is not intended for the benefit of holders of the LoTSsm and may not be enforced by them, and the Replacement Capital Covenant is not a term of the indenture or the LoTSsm.
Events of Default		The following will be events of default under the indenture governing the terms of the LoTSsm:
		• the failure to pay principal when due;
		• the failure to pay interest when due and payable that continues for 30 days, subject to the right to defer interest

		payments as described in “Description of the LoTSsm — Optional Deferral;”
		• the failure to pay deferred interest for ten consecutive years;
		• certain events of bankruptcy, insolvency or reorganization; or
		• Enterprise Parent’s guarantee of the LoTSsm ceases to be in full force and effect or is declared null and void in a judicial proceeding.
Use of Proceeds		We expect to use the net proceeds of this offering to temporarily reduce borrowings outstanding under our multi-year revolving credit facility and for general partnership purposes.
Expected Ratings		We expect that the LoTSsm will be rated Ba1/stable, B+/positive and BB+/stable by Moody’s Investor Services, Standard & Poor’s Rating Services and Fitch Ratings Ltd., respectively. Credit Ratings are intended to provide banks and capital market participants with a framework for comparing the credit quality of securities and are not a recommendation to buy, sell or hold these securities. Each rating may be subject to revision or withdrawal at any time and should be evaluated independently of any other rating.
Federal Income Tax Considerations		In connection with the issuance of the LoTSsm, Bracewell & Giuliani LLP will render its opinion to us that, for United States federal income tax purposes, the LoTSsm will be classified as indebtedness (although there is no clear authority directly on point). This opinion is subject to certain customary conditions. See “Certain United States Federal Income Tax Considerations.”
		Each purchaser of the LoTSsm agrees to treat the LoTSsm as indebtedness for all United States federal, state and local tax purposes. We intend to treat the LoTSsm in the same manner.
		If we elect to defer interest on the LoTSsm, the holders of the LoTSsm will be required to accrue income for United States federal income tax purposes in the amount of the accumulated interest payments on the LoTSsm, in the form of original issue discount, even though cash interest payments are deferred and even though they may be cash basis taxpayers.
Risk Factors		Investing in the LoTSsm involves certain risks. You should carefully consider the risk factors discussed under the heading “Risk Factors” beginning on page S-13 of this prospectus supplement and on page 3 of the accompanying prospectus and the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding to invest in the LoTSsm.
Trading		We do not expect to list the LoTSsm for trading on any securities exchange.
Trustee		Wells Fargo Bank, National Association.
Governing Law		The LoTSsm and the indenture will be governed by, and construed in accordance with, the laws of the State of New York.

RISK FACTORS

       An investment in the LoTS^sm involves certain risks. If any of these risks were to occur, our business, results of operations, cash flows and financial condition could be materially adversely affected. In that case, the value of the LoTS^sm could decline, and you could lose part or all of your investment.

Risks Relating to the LoTS^sm

We may elect to defer interest payments on the LoTS^SM at our option for one or more periods of up to ten consecutive years.

       We may elect to defer payment of all or part of the current and accrued interest otherwise due on the LoTS^sm for one or more periods of up to ten consecutive years, as described under “Description of the LoTS^sm — Optional Deferral of Interest.” If we exercise this option, you will not receive any current income on your investment in the LoTS^sm during such deferral period. In addition, although we are not permitted to defer payment of interest for more than ten consecutive years, we are permitted to defer interest for multiple periods of less than ten years without triggering an event of default.

We will not be able to pay current interest on the LoTS^SM until we have paid all Deferred Interest, which could have the effect of extending interest deferral periods.

       We will be prohibited from paying current interest on the LoTS^sm until we have paid all Deferred Interest on the LoTS^sm, even if we have cash available from other sources. As a result, we will not be able to pay current interest on the LoTS^sm, even if we have funds available to pay such current interest, if we do not have available funds to pay all Deferred Interest.

The LoTS^SM are subordinated to substantially all of our direct indebtedness.

       Our payment obligations under the LoTS^sm are unsecured and will be subordinate and rank junior in right of payment to all of our current and future “senior indebtedness,” including our indebtedness for borrowed money, indebtedness evidenced by bonds, debentures, notes or similar instruments, obligations arising from or with respect to guarantees and direct credit substitutes, obligations associated with hedges and derivative products, capitalized lease obligations and other senior indebtedness, excluding our trade account payables, certain other liabilities arising in the ordinary course of our business, any of our indebtedness which by its terms is expressly made equal in rank with or subordinated to the LoTS^sm and indebtedness owed by us to our majority-owned subsidiaries. We cannot make any payments on the LoTS^sm if we have defaulted on a payment of senior indebtedness and do not cure the default within the applicable grace period, or if the senior indebtedness becomes immediately due because of a default and has not yet been paid in full.

       As a result of the subordination provisions discussed in “Description of the LoTS^sm — Subordination; Ranking of the LoTS^sm,” in the event of our insolvency, funds that we would otherwise use to pay the holders of the LoTS^sm will be used to pay the holders of our senior indebtedness to the extent necessary to pay such indebtedness in full. As a result of those payments, the LoTS^sm may recover less, ratably, than the holders of our senior indebtedness. In addition, the holders of all of our senior indebtedness may, under certain circumstances, restrict or prohibit us from making payments on the LoTS^sm.

       The indenture does not limit our ability to incur additional indebtedness and other obligations, including indebtedness and other obligations that rank senior to or pari passu with the LoTS^sm. At March 31, 2006, the direct indebtedness of Enterprise that is senior to the LoTS^sm totaled approximately $4.4 billion. In addition, the LoTS^sm will be effectively subordinated to all of our subsidiaries’ and unconsolidated affiliates’ existing and future indebtedness and other obligations. At March 31, 2006, indebtedness of our subsidiaries and unconsolidated affiliates totaled approximately $562.7 million.

If interest on the LoTS^SM is deferred, holders of the LoTS^SM will be required to recognize income for United States federal income tax purposes at the time interest accrues regardless of their method of accounting before they actually receive interest payments in cash.

       If we defer interest payments on the LoTS^sm, each holder of the LoTS^sm will be required to accrue income for United States federal income tax purposes in the amount of the Deferred Interest on the LoTS^sm, in the form of original issue discount. In that event, you, as a holder of LoTS^sm,

The interest rate of the LoTS^SM will fluctuate when the fixed rate period ends, and may from time to time decline below the fixed rate.

       After the conclusion of the Fixed Rate Period for the LoTS^sm, on                     , 2016, the LoTS^sm will begin to bear interest at a floating rate equal to the 3-month LIBOR Rate for the related interest period plus        %. The floating rate may be volatile over time and could be substantially less than the fixed rate. In addition to experiencing a decline in current interest income, holders of the LoTS^sm could also encounter a reduction in the value of their LoTS^sm.

We may elect to cause the redemption of the LoTS^SM when prevailing interest rates are relatively low.

       We may redeem the LoTS^sm:

       We may choose to redeem the LoTS^sm for a variety of reasons, including when prevailing interest rates are lower than the then applicable interest rate on the LoTS^sm. In that case, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the LoTS^sm.

Enterprise Parent’s guarantee of the LoTS^SM is subordinate to all of its senior indebtedness.

       Enterprise Parent’s guarantee of the LoTS^sm will be subordinate and rank junior in right of payment to all of its current and future “senior indebtedness,” including Enterprise Parent’s indebtedness for borrowed money, indebtedness evidenced by bonds, debentures, notes or similar instruments, obligations arising from or with respect to guarantees and direct credit substitutes, obligations associated with hedges and derivative products, capitalized lease obligations and other senior indebtedness, excluding its trade account payables, certain other liabilities arising in the ordinary course of its business, any indebtedness which by its terms is expressly made equal in rank with or subordinated to its guarantee of the LoTS^sm and obligations owed by Enterprise Parent to its majority-owned subsidiaries. Enterprise Parent will not be permitted to make any payments under the guarantee if it has defaulted on a payment of senior indebtedness.

We may require cash from our subsidiaries to make payments on the LoTS^SM.

       We conduct the majority of our operations through our subsidiaries and unconsolidated affiliates, some of which are not wholly-owned, and we rely to a significant extent on interest payments, dividends, proceeds from inter-company transactions and loans from those entities to meet our obligations for payment of principal and interest on our outstanding debt obligations and corporate expenses, including interest payments on the LoTS^sm, which may be subject to contractual restrictions. Accordingly, the LoTS^sm

are structurally subordinated to all existing and future liabilities of our subsidiaries and unconsolidated affiliates. Holders of LoTS^sm should look only to our assets and the assets of Enterprise Parent, and not any of our subsidiaries or unconsolidated affiliates, for payments on the LoTS^sm. If we are unable to obtain cash from such entities to fund required payments in respect of the LoTS^sm, we may be unable to make payments of principal of or interest on the LoTS^sm.

Our right to redeem or repurchase the LoTS^SM is limited by a covenant that we are making in favor of certain other debtholders.

       By their terms, the LoTS^sm may be redeemed by us before their maturity as described in “Description of the LoTS^sm — Redemption.” However, around the time of the initial issuance of the LoTS^sm, we are entering into a “Replacement Capital Covenant,” which is described under “Certain Terms of the Replacement Capital Covenant,” that will limit our right to redeem or repurchase LoTS^sm. In the Replacement Capital Covenant, we covenant for the benefit of holders of a designated series of our long-term indebtedness that ranks senior to the LoTS^sm that we will not redeem or repurchase LoTS^sm on or before                     , 2036 unless, subject to certain limitations, during the 180 days prior to the date of that redemption or repurchase we, Enterprise Parent or one of our or its subsidiaries has received a specified amount of proceeds from the sale of qualifying securities that have characteristics that are the same as, or more equity-like than, the applicable characteristics of the LoTS^sm.

       Our ability to raise proceeds from the sale of securities that qualify under the Replacement Capital Covenant during the 180 days prior to a proposed redemption or repurchase will depend on, among other things, the condition of our business and our financial condition, market conditions at such time as well as the acceptability to prospective investors of the terms of those securities. Accordingly, there could be circumstances where we would wish to redeem or repurchase some or all of the LoTS^sm and sufficient cash is available for that purpose, but we are restricted from doing so because we have not been able to obtain proceeds from the sale of securities that qualify under the Replacement Capital Covenant.

The trustee has only limited rights of acceleration.

       The trustee may accelerate payment of the principal and accrued and unpaid interest on the LoTS^sm only upon the occurrence and continuation of an event of default. An event of default is generally limited to payment defaults after giving effect to our deferral rights, and specific events of bankruptcy, insolvency and reorganization relating to us. There is no right to acceleration upon breaches by us of other covenants under the indenture.

The tax accounting for the LoTS^SM is uncertain.

       We intend to treat the LoTS^sm as our indebtedness and to treat stated interest on the LoTS^sm as ordinary interest income that is includible in your gross income at the time the interest is paid or accrued, in accordance with your regular method of tax accounting. By purchasing the LoTS^sm you agree to report income on this basis. However, the determination of whether an instrument is indebtedness is an inherently factual one. Because there are no regulations, rulings or other authorities that address the United States federal income tax treatment of debt instruments that are substantially similar to the LoTS^sm, other treatments of the LoTS^sm are possible, and we can offer you no assurance that the Internal Revenue Service or a court would agree with our conclusion. See “Certain United States Federal Income Tax Considerations.”

A market may not develop for the LoTS^SM.

       The LoTS^sm constitute a new issue of securities with no established trading market and will not be listed on any exchange. An active market for the LoTS^sm may not develop or be sustained. As a result, we cannot assure you that you will be able to sell your LoTS^sm or at what price. Although the underwriters have indicated that they intend to make a market in the LoTS^sm, as permitted by applicable laws and regulations, they are not obligated to do so and may discontinue that market-making at any time without notice.

If a trading market develops for the LoTS^SM, trading may occur at prices that do not fully reflect the value of Deferred Interest and, as a result, a holder of LoTS^SM who disposes of his holdings between record dates for interest payments may incur an adverse tax effect.

       A holder of LoTS^sm who disposes of LoTS^sm between record dates for payments of interest will not receive an interest payment for the period prior to the disposition but nevertheless will be required to include accumulated but unpaid interest through the date of disposition as ordinary income in such holder’s gross income for United Stated federal income tax purposes. If a trading market develops, the LoTS^sm may trade at prices that do not fully reflect the value of Deferred Interest. As a result, a holder of LoTS^sm who sells LoTS^sm between record dates for interest payments may recognize a capital loss for tax purposes as a result of a portion of the sale proceeds being allocated to Deferred Interest. Any such capital loss may not be available to offset the ordinary income recognized as a result of the Deferred Interest because, subject to limited exceptions, capital losses cannot be applied to offset ordinary income for United States federal income tax purposes.

The aftermarket price of the LoTS^SM may be discounted significantly if we defer interest payments.

       If a deferral of an interest payment occurs or is perceived by the market as being likely to occur, you may be unable to sell your LoTS^sm at a price that reflects the value of Deferred Interest or the face amount of your LoTS^sm. To the extent a trading market develops for the LoTS^sm, that market may not continue during a deferral period, or during periods in which investors perceive that there is a likelihood of a deferral, and you may be unable to sell LoTS^sm at those times, either at a price that reflects the value of required payments under the LoTS^sm or at all.

There are restrictions on your ability to resell the LoTS^SM.

       The LoTS^sm may not be purchased by or transferred to certain types of benefit plans. See “Certain ERISA Considerations.”

A classification of the LoTS^SM as common equity by the National Association of Insurance Commissioners may impact U.S. insurance company investors and the value of the LoTS^SM.

       The Securities Valuation Office, or “SVO,” of the National Association of Insurance Commissioners, or “NAIC,” may from time to time classify securities in U.S. insurance company investors’ portfolios as debt, preferred equity or common equity instruments. Under the written guidelines outlined by the SVO, it is not always clear which securities will be classified as debt, preferred equity or common equity or which features are specifically relevant in making this determination. We understand that the SVO is currently reviewing a number of securities for classification, some of which may have structural features similar to the LoTS^sm. We are also aware that the SVO has classified several securities with structural features similar to the LoTS^sm, either definitively or preliminarily, as common equity. For this reason, there is a risk that the LoTS^sm may be classified as common equity, if reviewed and classified by the SVO. The NAIC classification of an investment directly affects certain U.S. insurance company investors because it determines the amount of capital required for such an investment by such investors, but it is not determinative in any way in respect of any other tax, accounting or legal considerations for investors generally. If the NAIC were to classify the LoTS^sm as common equity, the willingness of certain U.S. insurance company investors to hold the LoTS^sm could be reduced, which in turn could reduce the price of the LoTS^sm in any available after-market.

Risks Related to Our Business

       We are incorporating in this section by reference and you should review and consider carefully the risk factors related to our partnership and business contained in Enterprise Parent’s Annual Report on Form 10-K for the year ended December 31, 2005, which it filed with the Securities and Exchange Commission on February 27, 2006 and which is incorporated by reference herein. Set forth below are certain of the risk factors appearing in Enterprise Parent’s Annual Report on Form 10-K.

Changes in the prices of hydrocarbon products may materially adversely affect our results of operations, cash flows and financial condition.

       We operate predominantly in the midstream energy sector which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs and crude oil. As such, our results of operations, cash flows and financial condition may be materially adversely affected by changes in the prices of these hydrocarbon products and by changes in the relative price levels among these hydrocarbon products. Generally, the prices of natural gas, NGLs, crude oil and other hydrocarbon products are subject to fluctuations in response to changes in supply, demand, market uncertainty and a variety of additional factors that are impossible to control. These factors include:

       We are exposed to natural gas and NGL commodity price risk under certain of our natural gas processing and gathering and NGL fractionation contracts that provide for our fees to be calculated based on a regional natural gas or NGL price index or to be paid in-kind by taking title to natural gas or NGLs. A decrease in natural gas and NGL prices can result in lower margins from these contracts, which may materially adversely affect our results of operations, cash flows and financial position.

A decline in the volume of natural gas, NGLs and crude oil delivered to our facilities could adversely affect our results of operations, cash flows and financial condition.

       Our profitability could be materially impacted by a decline in the volume of natural gas, NGLs and crude oil transported, gathered or processed at our facilities. A material decrease in natural gas or crude oil production or crude oil refining, as a result of depressed commodity prices, a decrease in exploration and development activities or otherwise, could result in a decline in the volume of natural gas, NGLs and crude oil handled by our facilities.

       The crude oil, natural gas and NGLs available to our facilities will be derived from reserves produced from existing wells, which reserves naturally decline over time. To offset this natural decline, our facilities will need access to additional reserves. Additionally, some of our facilities will be dependent on reserves that are expected to be produced from newly discovered properties that are currently being developed.

       Exploration and development of new oil and natural gas reserves is capital intensive, particularly offshore in the Gulf of Mexico. Many economic and business factors are beyond our control and can adversely affect the decision by producers to explore for and develop new reserves. These factors could include relatively low oil and natural gas prices, cost and availability of equipment and labor, regulatory changes, capital budget limitations, the lack of available capital or the probability of success in finding hydrocarbons. For example, a sustained decline in the price of natural gas and crude oil could result in a decrease in natural gas and crude oil exploration and development activities in the regions where our facilities are located. This could result in a decrease in volumes to our offshore platforms, natural gas processing plants, natural gas, crude oil and NGL pipelines, and NGL fractionators, which would have a material adverse affect on our results of operations, cash flows and financial position. Additional reserves, if discovered, may not be developed in the near future or at all.

A decrease in demand for NGL products by the petrochemical, refining or heating industries could materially adversely affect our results of operations, cash flows and financial position.

       A decrease in demand for NGL products by the petrochemical, refining or heating industries, whether because of general economic conditions, reduced demand by consumers for the end products made with NGL products, increased competition from petroleum-based products due to pricing differences, adverse weather conditions, government regulations affecting prices and production levels of natural gas or the content of motor gasoline or other reasons, could materially adversely affect our results of operations, cash flows and financial position. For example:

       Ethane. If natural gas prices increase significantly in relation to ethane prices, it may be more profitable for natural gas producers to leave the ethane in the natural gas stream to be burned as fuel than to extract the ethane from the mixed NGL stream for sale.

       Propane. The demand for propane as a heating fuel is significantly affected by weather conditions. Unusually warm winters could cause the demand for propane to decline significantly and could cause a significant decline in the volumes of propane that we transport.

       Isobutane. A reduction in demand for motor gasoline additives may reduce demand for isobutane. During periods in which the difference in market prices between isobutane and normal butane is low or inventory values are high relative to current prices for normal butane or isobutane, our operating margin from selling isobutane could be reduced.

       Propylene. A downturn in the domestic or international economy could cause reduced demand for propylene, which could cause a reduction in the volumes of propylene that we produce and expose our investment in inventories of propane/propylene mix to pricing risk due to requirements for short-term price discounts in the spot or short-term propylene markets.

If we were to become subject to entity level taxation for federal or state tax purposes, then our cash available for payment on the LoTS^SM would be substantially reduced.

       If we were treated as a corporation for United States federal income tax purposes, we would pay United States federal income tax on our taxable income at the corporate tax rate, which is currently a maximum of 35%, and we likely would pay state taxes as well. Because a tax would be imposed upon us as a corporation, the cash available for payment on the LoTS^sm would be substantially reduced. Therefore, treatment of us as a corporation would result in a material reduction in our anticipated cash flows and could cause a reduction in the value of the LoTS^sm.

       Current law may change, causing us to be treated as a corporation for United States federal income tax purposes or otherwise subjecting us to entity level taxation. For example, because of widespread state budget deficits, certain states, including Texas, have taken steps to subject partnerships to entity level taxation through the imposition of state income, franchise or other forms of taxation. If these activities continue, the cash available for payment on the LoTS^sm would be reduced.

A successful IRS contest of the United States federal income tax positions we take may adversely impact the market for the LoTS^SM, and the costs of any contests will reduce cash available for payment on the LoTS^SM.

       The IRS may adopt positions that differ from the positions we take, even positions taken with advice of counsel. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS may materially and adversely impact the market for the LoTS^sm. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in the amount of cash available to us to pay the principal of, and interest and premium, if any, on the LoTS^sm.

USE OF PROCEEDS

       We expect to receive aggregate net proceeds of approximately $           million from the sale of the LoTS^SM to the underwriters after deducting the underwriters’ discounts and commission and other offering expenses payable by us. We expect to use the net proceeds of this offering to temporarily reduce borrowings outstanding under our multi-year revolving credit facility and for general partnership purposes.

       In general, our indebtedness under the multi-year revolving credit facility was incurred for working capital purposes, capital expenditures and business combinations. Amounts repaid under our multi-year revolving credit facility may be reborrowed from time to time for acquisitions, capital expenditures and other general partnership purposes. As of July 6, 2006, we had $605.0 million of borrowings outstanding under our multi-year revolving credit facility that bears interest at a variable rate, which is currently approximately 5.82% per annum. Commitments of $48 million under our multi-year revolving credit facility mature in October 2010 and $1.2 billion of such commitments mature in October 2011. Affiliates of certain of the underwriters or their affiliates are lenders under our multi-year revolving credit facility and, accordingly, will receive a portion of the proceeds of this offering.

DESCRIPTION OF THE LOTS^sm

       We have summarized below certain material terms and provisions of the LoTS^sm. This summary is not a complete description of all of the terms and provisions of the LoTS^SM. You should read carefully the section entitled “Description of Debt Securities” in the accompanying prospectus for a description of other material terms of the LoTS^SM, the Guarantee and the indenture. For more information, we refer you to the LoTS^SM, the indenture and the supplemental indenture, forms of which are available from us. We urge you to read the indenture and supplemental indenture because they, and not this description, define your rights as an owner of the LoTS^SM.

       The LoTS^sm are a new series of debt securities that will be issued under an Indenture dated as of October 4, 2004 among Enterprise Products Operating L.P., as issuer, Enterprise Products Partners L.P., as parent guarantor, any subsidiary guarantors party thereto, and Wells Fargo Bank, National Association, as trustee, as supplemented by a supplemental indenture establishing the terms of the LoTS^sm, which we refer to collectively as the “indenture.” References in this section to “Enterprise” and the terms “we”, “us”, “our” and like phrases refer solely to Enterprise Products Operating L.P. and do not include our parent, Enterprise Products Partners L.P., or any of our subsidiaries or unconsolidated affiliates. References in this section to the “Parent Guarantor” refer solely to Enterprise Products Partners L.P. and not its subsidiaries or unconsolidated affiliates. References in this section to the “Guarantee” refer to the Parent Guarantor’s guarantee of payments on the LoTS^sm.

       In addition to this new series of LoTS^sm, as of March 31, 2006, there were outstanding under the above-referenced indenture $500 million in aggregate principal amount of 4.000% senior notes E due 2007, $500 million in aggregate principal amount of 4.625% senior notes F due 2009, $650 million in aggregate principal amount of 5.600% senior notes G due 2014, $350 million in aggregate principal amount of

6.650% senior notes H due 2034, $250 million in aggregate principal amount of 5.00% senior notes I due 2015, $250 million in aggregate principal amount of 5.75% senior notes J due 2035 and $500 million in aggregate principal amount of 4.950% senior notes K due 2010.

General

       The LoTS^sm:

       The indenture does not limit our incurrence or issuance of other senior, pari passu or subordinated debt, whether under the indenture relating to the LoTS^sm or any existing or other indenture or agreement that we may enter into in the future or otherwise. As of March 31, 2006, the direct indebtedness of Enterprise that is senior to the LoTS^sm totaled approximately $4.4 billion.

Interest Rate and Interest Payment Dates

       The LoTS^sm will bear interest from the date of issuance to                     , 2016, which we refer to as the “Fixed Rate Period,” at an annual rate of      %, payable semi-annually in arrears on                     and                     of each year, commencing                     , 2007, and thereafter, which we refer to as the “Floating Rate Period,” at an annual rate equal to the 3-month LIBOR Rate for the related interest period plus      %, payable quarterly in arrears on                     ,                     ,                     and                     of each year commencing                     , 2016.

       Interest payments not paid when due will accrue interest at the then applicable rate of interest on the amount of unpaid interest, to the extent permitted by law, compounded semi-annually during the Fixed Rate Period and quarterly during the Floating Rate Period. The amount of interest payable during the Fixed Rate Period will be computed based on a 360-day year consisting of twelve 30-day months, and the amount of interest payable during the Floating Rate Period will be computed based on a 360-day year and the number of days actually elapsed.

       The amount of interest payable for any period shorter than a full quarterly period will be computed on the basis of the actual number of days elapsed per 30-day month.

Maturity

       The LoTS^sm will mature on                     , 2066.

       The LoTS^sm are non-amortizing and do not have a sinking fund. This means that we are not required to make any principal payments prior to maturity or otherwise set aside amounts in respect of the repayment of the LoTS^sm prior to their maturity.

Determining the Floating Rate

       Following                     , 2016, the calculation agent will calculate the floating rate with respect to each interest period and the amount of interest payable on each interest payment date during the Floating Rate Period. The floating rate determined by the calculation agent, absent manifest error, will be binding and conclusive upon the beneficial owners and registered holders of the LoTS^sm and us. Wells Fargo Bank, National Association will act initially as calculation agent.

       The floating rate for any interest period during the Floating Rate Period will be the 3-month LIBOR Rate plus      %.

       The “3-month LIBOR Rate” means, for each interest period during the floating rate period, the interest rate per annum shown on Telerate Page 3750 at or about 11:00 a.m., London time, on the second London banking day (the “LIBOR Determination Date”) preceding the first day of the interest period (the “Reset Date”) for deposits in U.S. dollars with a maturity of three months and commencing on the Reset Date. If such rate does not appear on that page or such other page as may replace that page for the purpose of displaying offered rates of leading banks for London interbank deposits in U.S. dollars, the 3-month LIBOR Rate will be determined on the basis of the rates, at approximately 11:00 a.m., London time, on the LIBOR Determination Date, at which U.S. dollar deposits with a maturity of three months in an amount determined by the calculation agent as representative of a single transaction in the relevant market and at the relevant time are offered by four major banks in the London interbank market selected by the calculation agent (“Reference Banks”) to prime banks in the London interbank market for the interest period commencing on the Reset Date. The calculation agent will request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two quotations are provided as requested, the 3-month LIBOR Rate will be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the 3-month LIBOR Rate will be the interest rate per annum equal to the average of the rates per annum quoted by three major banks in New York City or Charlotte, North Carolina selected by the calculation agent, at or about 11:00 a.m., New York City time, on the LIBOR Determination Date, for loans in U.S. dollars to leading European banks in amounts that are representative of a single transaction in the relevant market and at the relevant time with a maturity corresponding to the interest period and commencing on the Reset Date. If fewer than three New York City or Charlotte, North Carolina banks selected by the calculation agent are quoting rates, the 3-month LIBOR Rate for the applicable interest period will be the same as for the immediately preceding interest period. For purposes of this definition, “London banking day” means any day on which commercial banks are open for general business (including dealings in foreign exchange and foreign currency deposits) in London, England. If the interest period does not correspond to a period for which rates are available, the 3-month LIBOR Rate will be determined through the use of straight-line interpolation by reference to two rates, the first rate to be determined by reference to the period of time for which rates are available next shorter than the length of the interest period and the second to be determined by reference to the period of time for which rates are available next longer than the length of the interest period.

       “Telerate Page 3750” means the display designated on page 3750 on MoneyLine Telerate (or on any successor or substitute page of such service, or any successor to or substitute for such service, providing rate quotations comparable to those currently provided on such page).

Payment and Transfer

       Initially, the LoTS^sm will be issued only in global form. Beneficial interests in LoTS^sm in global form will be shown on, and transfers of interests in LoTS^sm in global form will be made only through, records maintained by DTC and its participants. LoTS^sm in definitive form, if any, may be presented for registration of transfer or exchange at the office or agency maintained by us for such purpose (which initially will be the corporate trust office of the trustee located at 45 Broadway, 12th Floor, New York, New York 10006).

       Payment of principal of, premium, if any, and interest on LoTS^sm in global form registered in the name of DTC’s nominee will be made in immediately available funds to DTC’s nominee, as the registered

holder of such global notes. If any of the LoTS^sm is no longer represented by a global note, payment of interest on the LoTS^sm in definitive form may, at our option, be made at the corporate trust office of the trustee indicated above or by check mailed directly to holders at their respective registered addresses or by wire transfer to an account designated by a holder.

       The regular record date for interest payable on the LoTS^sm on any interest payment date during the Fixed Rate Period will be the immediately preceding                     or                     , as the case may be, and during the Floating Rate Period will be the immediately preceding                     ,                     ,                     or                     , as the case may be.

       No service charge will be made for any registration of transfer or exchange of LoTS^sm, but we may require payment of a sum sufficient to cover any transfer tax or other governmental charge payable in connection therewith. We are not required to register the transfer of or exchange any LoTS^sm selected for redemption or for a period of 15 days before mailing a notice of redemption of LoTS^sm.

       The registered holder of LoTS^sm will be treated as the owner of such LoTS^sm for all purposes, and all references in this Description of the LoTS^sm to “holders” mean holders of record, unless otherwise indicated.

Optional Deferral of Interest

       So long as no event of default (as defined below under “— Events of Default”) has occurred and is continuing, we may elect to defer payment of all or part of the current and accrued interest otherwise due on the LoTS^sm provided that:

       Deferred interest not paid on an interest payment date will bear interest from that interest payment date until paid at the then prevailing interest rate on the LoTS^sm, compounded semi-annually during the Fixed Rate Period and quarterly during the Floating Rate period. We refer to such deferred interest, the interest accrued thereon and any accrued and unpaid interest on any interest payment date during a deferral period collectively as “Deferred Interest,” and we refer to a period during which we have elected to defer payment of interest on the LoTS^sm as an “Optional Deferral Period.” Once we pay all Deferred Interest resulting from our optional deferral, such Optional Deferral Period will end and we may later defer interest again for a new Optional Deferral Period, subject to the same limitations described above.

       We will provide the trustee with written notice of any optional deferral of interest at least ten and not more than 60 business days prior to the applicable interest payment date, other than in the case of an optional deferral in connection with certain defaults on senior indebtedness as described under “— Subordination; Ranking of the LoTS^sm,” and any such notice will be forwarded promptly by the trustee to each holder of record of the LoTS^sm.

       We have no current intention to exercise our right to defer interest payments.

Distribution Stopper

       Unless each of the following conditions, which we refer to as “Payment Conditions,” has been satisfied:

       then, subject to the exceptions described below:

       Notwithstanding the foregoing, we, the Parent Guarantor and any of our respective subsidiaries may take any of the following actions at any time, including during an Optional Deferral Period:

Redemption

       We may redeem the LoTS^sm before their maturity, subject to the Replacement Capital Covenant discussed in “Certain Terms of the Replacement Capital Covenant”:

       LoTS^sm called for redemption become due on the redemption date. Notices of optional redemption will be mailed at least 30 but not more than 60 days before the redemption date to each holder of LoTS^sm to be redeemed at its registered address. The notice of optional redemption for the LoTS^sm will state, among other things, the amount of LoTS^sm to be redeemed, the redemption date, the method of calculating the redemption price and each place that payment will be made upon presentation and surrender of LoTS^sm to be redeemed. If less than all of the LoTS^sm are redeemed at any time, the trustee will select the LoTS^sm to be redeemed on a pro rata basis or by any other method the trustee deems fair and appropriate. Unless we default in payment of the redemption price, interest will cease to accrue on the redemption date with respect to any LoTS^sm called for optional redemption.

Early Redemption

       We may redeem the LoTS^sm in whole or in part at any time prior to                     , 2016 upon payment of the Make-Whole Redemption Price.

       The “Make-Whole Redemption Price” will be equal to (a) all accrued and unpaid interest to but not including the redemption date, plus (b) the greater of (1) 100% of the principal amount of the LoTS^sm being redeemed and (2) as determined by the Independent Investment Banker, the sum of the present values of remaining scheduled payments of principal and interest on the LoTS^sm (exclusive of interest accrued to the redemption date) being redeemed from the redemption date to                     , 2016 (the “Remaining Life”), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus      %.

       “Treasury Yield” means, with respect to any redemption date applicable to the LoTS^sm, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding the redemption date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for the redemption date.

       “Comparable Treasury Price” means, with respect to any redemption date, (a) the bid price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) at 4:00 p.m. on the third business day preceding the redemption date, as set forth on Telerate Page 500 (or such other page as may replace Telerate Page 500), or (b) if such page (or any successor page) is not displayed or does not contain such bid prices at such time, the average of the Reference Treasury Dealer Quotations obtained by the trustee for the redemption date.

       “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the Remaining Life that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Remaining Life; however, if no maturity is within three months before or after the end of the Remaining Life, yields for two published maturities most closely corresponding to such United States Treasury security will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight-line basis, rounding to the nearest month.

       “Independent Investment Banker” means any of Wachovia Capital Markets, LLC (and its successors) and Lehman Brothers Inc. (and its successors) or, if no such firm is willing and able to select the applicable Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the trustee and reasonably acceptable to us.

       “Reference Treasury Dealer” means (a) Wachovia Capital Markets, LLC (and its successors) and (b) one other primary United States government securities dealer in New York City selected by the Independent Investment Banker, each of which we refer to as a “Primary Treasury Dealer.” However, if either of the foregoing ceases to be a Primary Treasury Dealer, we will substitute another Primary Treasury Dealer for such dealer.

       “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date for the LoTS^sm, an average, as determined by the trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date.

Certain Covenants

       No Limitations on Liens. Holders of the LoTS^sm will not have the benefit of and will not be entitled to enforce the covenant in the indenture restricting the ability of the Parent Guarantor, Enterprise and their respective majority-owned subsidiaries to, create, assume, incur or suffer to exist any mortgage, lien, security interest, pledge, charge or other encumbrance other than Permitted Liens (as defined in

“Description of Debt Securities — Certain Covenants” in the accompanying prospectus) upon any Principal Property (as defined in “Description of Debt Securities — Certain Covenants” in the accompanying prospectus) or upon any shares of capital stock of any majority-owned subsidiary owning or leasing, either directly or through ownership in another majority-owned subsidiary, any Principal Property, whether owned or leased on the date of the indenture or thereafter acquired, to secure any indebtedness for borrowed money of the Parent Guarantor or Enterprise or any other person.

       No Restriction on Sale-Leasebacks. Holders of the LoTS^sm will not have the benefit of and will not be entitled to enforce the covenant in the indenture restricting the ability of the Parent Guarantor, Enterprise and their respective majority-owned subsidiaries to enter into Sale-Leaseback Transactions (as defined in “Description of Debt Securities — Certain Covenants” in the accompanying prospectus).

       Merger, Consolidation or Sale of Assets. Each of the Parent Guarantor and Enterprise will be subject to the restriction in the indenture governing its ability to consolidate with or sell, lease, convey all or substantially all of its assets to, or merge with or into, any partnership, limited liability company or corporation, as described in “Description of Debt Securities — Certain Covenants” in the accompanying prospectus.

Events of Default

       Any one or more of the following events that has occurred and is continuing will constitute an event of default:

       If an event of default (other than an event of default described in the fourth bullet point above) occurs and is continuing, the trustee by notice to us, or the holders of at least 25% in principal amount of the outstanding LoTS^sm by notice to us and the trustee, may, and the trustee at the request of such holders will, declare the principal of, premium, if any, and interest, including Deferred Interest, if any, on all the LoTS^sm to be due and payable. Upon such a declaration, such principal, premium and interest will be due and payable immediately.

       If an event of default described in the fourth bullet point above occurs and is continuing, the principal of, premium, if any, and interest, including Deferred Interest, if any, on all the LoTS^sm will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holders. However, the effect of such provision may be limited by applicable law. The holders of a majority in principal amount of the outstanding LoTS^sm may rescind any such acceleration with respect to the LoTS^sm and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction and all existing events of default with respect to the LoTS^sm, other than the nonpayment of the principal of, premium, if any, and interest on the LoTS^sm that have become due solely by such declaration of acceleration, have been cured or waived.

Subordination; Ranking of the LoTS^sm

       Our payment obligations under the LoTS^sm will, to the extent provided in the indenture, be subordinated to the prior payment in full of all of our present and future senior indebtedness, as defined below. The LoTS^sm will rank senior in right of payment to all of our present and future equity securities.

       The holders of our senior indebtedness will be entitled to receive payment in full of such senior indebtedness before holders of the LoTS^sm will receive any payment of principal, premium or interest with respect to the LoTS^sm:

       In these circumstances, until our senior indebtedness is paid in full, any distribution to which holders of LoTS^sm would otherwise be entitled will be made to the holders of senior indebtedness, except that such holders may receive units representing limited partner interests and debt securities that are subordinated to senior indebtedness to at least the same extent as the LoTS^sm.

       If we do not pay any principal, premium or interest with respect to senior indebtedness within any applicable grace period (including at maturity), or any other default on senior indebtedness occurs and the maturity of such senior indebtedness is accelerated in accordance with its terms, we may not:

       unless, in either case,

       During the continuance of any senior indebtedness default, other than a default described in the immediately preceding paragraph, that may cause the maturity of any designated senior indebtedness to be accelerated immediately without further notice, other than any notice required to effect such acceleration, or the expiration of any applicable grace periods, we may not make payments on the LoTS^sm for a period called the “Payment Blockage Period.” A Payment Blockage Period will commence on the receipt by us and the trustee of written notice of the default, called a “Blockage Notice,” from the representative of any designated senior indebtedness specifying an election to effect a Payment Blockage Period, and will expire 179 days thereafter.

       Generally, “designated senior indebtedness” will include any issue of senior indebtedness of at least $100 million.

       The Payment Blockage Period may be terminated before its expiration:

Unless the holders of designated senior indebtedness shall have accelerated the maturity of the senior indebtedness, we may resume payments on the LoTS^sm after the expiration of the Payment Blockage Period.

       If we do not pay principal, premium or interest with respect to senior indebtedness within any applicable grace period, if any other default on senior indebtedness occurs and the maturity of such senior indebtedness is accelerated in accordance with its terms or if we receive a Blockage Notice, then, notwithstanding the notice periods set forth under “— Optional Deferral of Interest,” we may elect to defer payment of all or part of the current and accrued interest otherwise due on the LoTS^sm on an interest payment date by giving notice to the trustee of such election not later than the time we must remit payment of interest on the LoTS^sm to the trustee under the supplemental indenture on such interest payment date. Any such notice will be forwarded promptly by the trustee to each holder of record of the LoTS^sm. However, we may only exercise this right if we are otherwise entitled to elect to optionally defer payment of interest on the LoTS^sm as described under “— Optional Deferral of Interest.”

       Generally, not more than one Blockage Notice may be given in any period of 360 consecutive days. The total number of days during which any one or more Payment Blockage Periods are in effect, however, may not exceed an aggregate of 179 days during any period of 360 consecutive days.

       After all senior indebtedness is paid in full and until the LoTS^sm are paid in full, holders of the LoTS^sm will be subrogated to the rights of holders of senior indebtedness to receive distributions applicable to senior indebtedness.

       By reason of the subordination, in the event of our insolvency, our creditors who are holders of senior indebtedness, as well as certain of our general creditors, may recover more, ratably, than the holders of the LoTS^sm.

       The term “senior indebtedness” as used in this section includes our obligations in respect of the principal of, any interest and premium, if any, on and any other payments in respect of any of the following, whether currently outstanding or hereafter created or incurred:

       but does not include our obligations in respect of:

       The indenture does not limit our ability to incur additional indebtedness and other obligations, including indebtedness and other obligations that rank senior in priority of payment to or pari passu with the LoTS^sm. At March 31, 2006, the direct indebtedness of Enterprise that is senior to the LoTS^sm totaled approximately $4.4 billion. In addition, the LoTS^sm will be effectively subordinated to all of our subsidiaries’ and unconsolidated affiliates’ existing and future indebtedness and other obligations. At March 31, 2006, indebtedness of our subsidiaries and unconsolidated affiliates totaled approximately $562.7 million.

Parent Guarantee

       The Parent Guarantor will fully and unconditionally guarantee on an unsecured and junior subordinated basis the full and prompt payment of principal of, premium, if any, and interest on the LoTS^sm, when and as the same become due and payable (other than during an Optional Deferral Period), whether at stated maturity, upon redemption, by declaration of acceleration or otherwise.

       The Parent Guarantor’s obligations under the Guarantee will, to the extent provided in the indenture, be subordinated to the prior payment in full of all present and future senior indebtedness of the Parent Guarantor, as defined below. The Parent Guarantor’s obligations under the Guarantee will rank senior in right of payment to all of its present and future equity securities, including its common units.

       The holders of the Parent Guarantor’s senior indebtedness will be entitled to receive payment in full of such senior indebtedness before holders of the LoTS^sm receive from the Parent Guarantor any payment of principal, premium or interest with respect to the LoTS^sm:

       In these circumstances, until the Parent Guarantor’s senior indebtedness is paid in full, any distribution to which holders of LoTS^sm would otherwise be entitled under the Guarantee will be made to the holders of its senior indebtedness, except that such holders may receive units representing limited partner interests and any debt securities that are subordinated to senior indebtedness to at least the same extent as the Guarantee.

       If the Parent Guarantor does not pay any principal, premium or interest with respect to its senior indebtedness within any applicable grace period (including at maturity), or any other default on its senior indebtedness occurs and the maturity of such senior indebtedness is accelerated in accordance with its terms, the Parent Guarantor may not:

       unless, in either case,

       During the continuance of any senior indebtedness default, other than a default described in the immediately preceding paragraph, that may cause the maturity of any designated senior indebtedness to be accelerated immediately without further notice, other than any notice required to effect such acceleration, or the expiration of any applicable grace periods, the Parent Guarantor may not make payments under the Guarantee in respect of the LoTS^sm for a period called the “Payment Blockage Period.” A Payment Blockage Period will commence on the receipt by the Parent Guarantor and the trustee of written notice of the default, called a “Blockage Notice,” from the representative of any designated senior indebtedness specifying an election to effect a Payment Blockage Period, and will expire 179 days thereafter.

       Generally, “designated senior indebtedness” will include any issue of senior indebtedness of at least $100 million.

       The Payment Blockage Period may be terminated before its expiration:

Unless the holders of the designated senior indebtedness shall have accelerated the maturity of the senior indebtedness, the Parent Guarantor may resume making payments under the Guarantee in respect of the LoTS^sm after the expiration of the Payment Blockage Period.

       Generally, not more than one Blockage Notice may be given in any period of 360 consecutive days. The total number of days during which any one or more Payment Blockage Periods are in effect, however, may not exceed an aggregate of 179 days during any period of 360 consecutive days.

       After all senior indebtedness is paid in full and until the LoTS^sm are paid in full, holders of the LoTS^sm will be subrogated to the rights of holders of senior indebtedness to receive distributions applicable to senior indebtedness.

       By reason of the subordination, in the event of the Parent Guarantor’s insolvency, its creditors who are holders of senior indebtedness, as well as certain of its general creditors, may recover more, ratably, than the holders of the LoTS^sm will recover under the Guarantee.

       The term “senior indebtedness” as used in this section includes the Parent Guarantor’s obligations in respect of the principal of, any interest and premium, if any, on and any other payments in respect of any of the following, whether currently outstanding or hereafter created or incurred:

       but does not include the Parent Guarantor’s obligations in respect of:

       The obligations under the Guarantee will be structurally subordinated to all indebtedness and other liabilities of the Parent Guarantor’s subsidiaries and unconsolidated affiliates. In the event of an insolvency, liquidation, bankruptcy proceeding or other reorganization of any such entity all of the existing and future liabilities of such entity, including any claims of lessors under capital and operating leases, trade creditors and holders of preferred stock or units of that entity have the right to be satisfied prior to receipt by the Parent Guarantor of any payment on account of its status as an equity owner of such entity. Moreover, the Guarantee does not limit the Parent Guarantor or any of its subsidiaries or unconsolidated affiliates from incurring or issuing other secured or unsecured debt, including senior indebtedness. Accordingly, claimants under the Guarantee should look only to the Parent Guarantor and not to any of its subsidiaries or unconsolidated affiliates for payments under the Guarantee.

Agreement by Purchasers of Certain Tax Treatment

       Each registered holder and beneficial owner of the LoTS^sm will, by accepting the LoTS^sm or a beneficial interest therein, be deemed to have agreed that the holder intends that the LoTS^sm constitute debt and will treat the LoTS^sm as debt for United States federal, state and local tax purposes.

CERTAIN TERMS OF THE REPLACEMENT CAPITAL COVENANT

       We have summarized below certain terms of the Replacement Capital Covenant. This summary is not a complete description of the Replacement Capital Covenant and is qualified in its entirety by the terms and provisions of the full document.

       We will covenant in the Replacement Capital Covenant for the benefit of persons that buy, hold or sell a specified series of our long-term indebtedness that ranks senior to the LoTS^sm, that we will not redeem or repurchase LoTS^sm on or before                     , 2036, unless, subject to certain limitations, during the 180 days prior to the date of that redemption or repurchase we, Enterprise Parent or one of our or its subsidiaries receives a specified amount of proceeds from the sale of qualifying securities that have characteristics that are the same as, or more equity-like than, the applicable characteristics of the LoTS^sm.

       Our covenants in the Replacement Capital Covenant run only to the benefit of holders of the designated series of our long-term indebtedness. The Replacement Capital Covenant is not intended for the benefit of holders of the LoTS^sm and may not be enforced by them, and the Replacement Capital Covenant is not a term of the indenture or the LoTS^sm.

       Our ability to raise proceeds from qualifying securities during the 180 days prior to a proposed redemption or repurchase of the LoTS^sm will depend on, among other things, the condition of our business and our financial condition, market conditions at that time as well as the acceptability to prospective investors of the terms of those qualifying securities.

       The Replacement Capital Covenant may be terminated if the holders of at least a majority by principal amount of the then existing covered debt agree to terminate the Replacement Capital Covenant, or if we no longer have outstanding any indebtedness that qualifies as covered debt, and will terminate on                     , 2036 if not terminated earlier.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

       The following summary describes certain United States federal income tax considerations associated with the purchase, ownership and disposition of the LoTS^sm by United States Holders (as defined below) and non-United States Holders (as defined below), as of the date of this prospectus supplement. Except where noted, this summary deals only with the LoTS^sm held as capital assets by holders who acquired the LoTS^sm upon their original issuance at their public offering price set forth on the cover of this prospectus supplement. Some holders (including banks, insurance companies, tax-exempt organizations, financial institutions, regulated investment companies, mutual funds, persons whose functional currency is not the U.S. dollar, persons subject to alternative minimum tax, broker-dealers, persons that hold the LoTS^sm as part of a straddle, hedge, conversion transaction or other integrated investment, expatriates, controlled foreign corporations, passive foreign investment companies and corporations that accumulate earnings to avoid United States federal income tax) may be subject to special rules not discussed below. The discussion below does not address the effect of any state, local or foreign tax law.

       Furthermore, the discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as of the date of this prospectus supplement. Because the foregoing are subject to change or differing interpretations, possibly on a retroactive basis, the United States federal income tax consequences of an investment in the LoTS^sm may be different from those discussed below.

       A “United States Holder” of the LoTS^sm means a holder that is for United States federal income tax purposes:

       A “non-United States holder” means a beneficial owner of the LoTS^sm that is for United States federal income tax purposes:

       If a partnership or other entity treated as a partnership for United States federal income tax purposes holds the LoTS^sm, the United States federal income tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding LoTS^sm, you should consult your own tax advisor on this, as well as other issues.

       There is no clear authority addressing the United States federal income tax treatment of the LoTS^sm. Accordingly, you should consult your tax advisor in determining the tax consequences to you of purchasing, holding and disposing of the LoTS^sm, including the application to your particular situation of the United States federal income tax considerations discussed below, as well as the application of state, local, or other tax laws.

Classification of the LoTS^sm

       In connection with the issuance of the LoTS^sm, Bracewell & Giuliani LLP, special tax counsel to us, will render its opinion to us generally to the effect that, under then current law and assuming full compliance with the terms of the indenture and other relevant documents, and based on the facts, assumptions and analysis contained in that opinion, as well as representations we make, the LoTS^sm will be classified for United States federal income tax purposes upon issuance as indebtedness of Enterprise (although there is no clear authority directly on point). That opinion will not be binding on the IRS or any court. The determination of whether an instrument is indebtedness for United States federal income tax purposes is an inherently factual one, dependent on all the facts and circumstances, with no one factor being conclusive. The remainder of this discussion assumes that the classification of the LoTS^sm as indebtedness of Enterprise will be respected for United States federal income tax purposes.

United States Holders

Interest Income and Original Issue Discount

       Under applicable Treasury regulations, a “remote” contingency that stated interest will not be timely paid will be ignored in determining whether a debt instrument is issued with original issue discount, or OID. We believe that the likelihood of our exercising our option to defer payments is remote within the meaning of the Treasury regulations. Based on the foregoing, we believe that the LoTS^sm will not be considered to be issued with OID at the time of their original issuance. Accordingly, each United States Holder of LoTS^sm should include in gross income that holder’s allocable share of interest on the LoTS^sm in accordance with that holder’s method of tax accounting.

       Under applicable Treasury regulations, if the option to defer any payment of interest was determined not to be “remote,” or if we exercised that option, the LoTS^sm would be treated as issued with OID at the time of issuance or at the time of that exercise, as the case may be. In that case, all stated interest on the LoTS^sm thereafter would be treated as OID as long as the LoTS^sm remained outstanding. Accordingly, all of a United States Holder’s taxable interest income relating to the LoTS^sm would constitute OID that would have to be included in income on an economic accrual basis before the receipt of the cash attributable to the interest, regardless of that holder’s method of tax accounting, and actual distributions of stated interest would not be reported as taxable income. Consequently, such a holder of LoTS^sm would be required to include OID in gross income even though we will not make actual payments on the LoTS^sm during a deferral period.

       No rulings or other interpretations have been issued by the IRS which have addressed the meaning of the term “remote” as used in the applicable Treasury regulations, and it is possible that the IRS could take a position contrary to the interpretation in this prospectus supplement.

       If the IRS were to challenge successfully the classification of the LoTS^sm as indebtedness, payments on the LoTS^sm likely would be treated as guaranteed payments or distributions with respect to a preferred partnership interest. In such case, United States Holders of the LoTS^sm that are employee benefit plans, and most other organizations exempt from United States federal income tax including individual retirement accounts and other retirement plans, could be subject to United States federal income tax on their income with respect to the LoTS^sm as unrelated business taxable income.

Sale, Exchange, Redemption or Retirement of the LoTS^SM

       Upon sale, exchange, redemption or retirement of the LoTS^sm, a United States Holder will recognize gain or loss equal to the difference between its adjusted tax basis in the LoTS^sm and the amount realized

on the sale, exchange, redemption or retirement of the LoTS^sm. Assuming that we do not exercise our option to defer payment of interest on the LoTS^sm and that the LoTS^sm are not deemed to be issued with OID, a United States Holder’s adjusted tax basis in the LoTS^sm generally will be that holder’s initial purchase price. If the LoTS^sm are deemed to be issued with OID, a United States Holder’s adjusted tax basis in the LoTS^sm generally will be its initial purchase price, increased by OID previously includible in that holder’s gross income to the date of disposition and decreased by distributions or other payments received on the LoTS^sm since and including the date that the LoTS^sm were deemed to be issued with OID. That gain or loss generally will be a capital gain or loss, except to the extent of any accrued interest relating to that United States Holder’s ratable share of the LoTS^sm required to be included in income, and generally will be a long-term capital gain or loss if the LoTS^sm have been held for more than one year. Capital losses generally cannot be applied to offset ordinary income for United States federal income tax purposes.

Information Reporting and Backup Withholding

       Generally, interest on the LoTS^sm will be subject to information reporting on Internal Revenue Service Form 1099-INT or, if interest on the LoTS^sm constitutes OID as discussed above under “— United States Holders — Interest Income and Original Issue Discount,” on Internal Revenue Service Form 1099-OID. In addition, United States Holders may be subject to a backup withholding tax on those payments if they do not provide their taxpayer identification numbers to the trustee in the manner required, fail to certify that they are not subject to backup withholding tax, or otherwise fail to comply with applicable backup withholding tax rules. United States Holders also may be subject to information reporting and backup withholding tax with respect to the proceeds from a sale, exchange, retirement or other taxable disposition of the LoTS^sm. Any amounts withheld under the backup withholding rules will be allowed as a credit against the United States Holder’s United States federal income tax liability, so long as the required information is timely furnished to the IRS.

Non-United States Holders

       No withholding of United States federal income tax will apply to interest paid on LoTS^sm to a non-United States Holder under the “portfolio interest exemption,” so long as:

       If a non-United States Holder cannot satisfy the requirements of the portfolio interest exemption described above, interest paid on the LoTS^sm (including payments in respect of OID, if any, on the LoTS^sm) made to a non-United States Holder should be subject to a 30% United States federal withholding tax, unless that non-United States Holder provides the withholding agent with a properly executed statement (i) claiming an exemption from or reduction of withholding under an applicable United States income tax treaty or (ii) stating that the interest is not subject to withholding tax because it is effectively connected with that non-United States Holder’s conduct of a trade or business in the United States.

       If a non-United States Holder is engaged in a trade or business in the United States (or, if an applicable United States income tax treaty applies, if the non-United States Holder maintains a permanent establishment within the United States) and the interest is effectively connected with the conduct of that trade or business (or, if an applicable United States income tax treaty applies, attributable to that permanent establishment), that non-United States Holder will be subject to United States federal income tax on the interest on a net income basis in the same manner as if that non-United States Holder were a United States Holder. In addition, a non-United States Holder that is a foreign corporation engaged in a trade or business in the United States may be subject to a 30% (or, if an applicable United States income tax treaty applies, a lower rate as provided) branch profits tax.

       Any gain realized on the sale, exchange, redemption or retirement of the LoTS^sm generally will not be subject to United States federal income tax unless:

       In general, backup withholding and information reporting will not apply to interest paid on the LoTS^sm to a non-United States Holder, or to proceeds from the sale, exchange, redemption or retirement of the LoTS^sm by a non-United States Holder, in each case, if the non-United States Holder certifies under penalties of perjury that it is a non-United States Holder and neither we nor our paying agent has actual knowledge (or reason to know) to the contrary. Any amounts withheld under the backup withholding rules will entitle such non-United States Holder to a credit against United States federal income tax liability and may entitle such non-United States Holder to a refund, so long as the required information is timely and properly furnished to the IRS. In general, if LoTS^sm are not held through a qualified intermediary, the amount of payments made on such LoTS^sm, the name and address of the beneficial owner and the amount, if any, of tax withheld may be reported to the IRS.

       Non-United States Holders should consult their tax advisors regarding the application of backup withholding in their particular situation, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if available.

       If the IRS were to challenge successfully the classification of the LoTS^sm as indebtedness, payments on the LoTS^sm likely would be treated as guaranteed payments or distributions with respect to a preferred partnership interest. In such case, non-United States Holders of the LoTS^sm would be treated as engaged in a trade or business within the United States, be required to file a United States federal income tax return and pay taxes on their share of our income or gain and be subject to withholding.

       THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER’S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE LoTS^sm, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.

CERTAIN ERISA CONSIDERATIONS

       A fiduciary of a pension, profit-sharing or other employee benefit plan subject to Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), a plan subject to Section 4975(e)(1) of the Internal Revenue Code of 1986, as amended (the “Code”), or an employee benefit plan or plan subject to any state or local law or other restrictions materially similar to Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) (each, a “Plan”), should consider the fiduciary

standards of ERISA or Similar Law in the context of such a Plan’s particular circumstances before authorizing an investment in the LoTS^sm. Among other factors, the fiduciary should consider whether such an investment is in accordance with the documents governing the plan and whether the investment is appropriate for the plan in view of its overall investment policy and diversification of its portfolio. The LoTS^sm may not be sold to any Plan unless either (i) the purchase and holding of the LoTS^sm would not be a transaction prohibited under Section 406 of ERISA, Section 4975 of the Code, and Similar Law or (ii) one of the following Prohibited Transaction Class Exemptions (“PTCE”) issued by the U.S. Department of Labor (or a materially similar exemption or exception under Similar Law) applies to the purchase, holding and disposition of the LoTS^sm:

       Any purchaser of the LoTS^sm or any interest therein will be deemed to have represented and warranted to us on each day from and including the date of its purchase of such LoTS^sm through and including the date of disposition of such LoTS^sm that either:

       (a) Plan assets under ERISA and the regulations issued thereunder, or under any Similar Law, are not being used to acquire the LoTS^sm; or

       (b) Plan assets as so defined are being used to acquire LoTS^sm but the purchase, holding and disposition of the LoTS^sm, either (1) are not and will not be a “prohibited transaction” within the meaning of ERISA, the Code or Similar Law or (2) are and will be an exempt prohibited transaction by one or more of the following prohibited transaction exemptions: PTCE 96-23, 95-60, 91-38, 90-1 or 84-14.

       The discussion set forth above is general in nature and is not intended to be complete. In addition, such discussion assumes that the LoTS^sm will constitute indebtedness as opposed to “equity” interests under the U.S. Department of Labor’s Plan asset regulations or Similar Law. Although such characterization of the LoTS^sm would appear appropriate, we can offer you no assurance that this will be the case. Accordingly, it is important that any person considering the purchase of LoTS^sm with Plan assets consult with its counsel regarding the consequences under ERISA, the Code or other Similar Law, of the acquisition and ownership of LoTS^sm. The sale of the LoTS^sm to a Plan is in no respect a representation by us or the underwriters that such an investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan.

UNDERWRITING

       We and the underwriters named below have entered into an underwriting agreement, dated July      , 2006, with respect to the LoTS^sm. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of LoTS^sm set forth opposite its name in the following table. Wachovia Capital Markets, LLC and Lehman Brothers Inc. are the representatives of the underwriters.

       The underwriters are committed to take and pay for all of the LoTS^sm being offered, if any are taken.

       We will pay as compensation to the underwriters discounts and commissions in the following amounts for the account of the underwriters.

       The LoTS^sm sold by the underwriters to the public will initially be offered at the public offering price set forth on the cover of this prospectus supplement. Any LoTS^sm sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to $           per LoTS^sm. If all the LoTS^sm are not sold at the public offering price, the underwriters may change the offering price and the other selling terms.

       The LoTS^sm are a new issue of securities with no established trading market. We have been advised by the underwriters that they presently intend to make a market in the LoTS^sm but they are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the LoTS^sm.

       In connection with this offering, the underwriters may purchase and sell the LoTS^sm in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of LoTS^sm than they are required to purchase in this offering. Stabilizing transactions consist of certain bids for or purchases of LoTS^sm made by the underwriters in the open market prior to the completion of this offering.

       The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased LoTS^sm sold by or for the account of such underwriter in stabilizing or short covering transactions.

       Purchases to cover a short position and stabilizing transactions may have the effect of preventing or retarding a decline in the market price of the LoTS^sm, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the LoTS^sm. As a result, the price of the LoTS^sm may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in over-the-counter market or otherwise.

       We estimate that our total out-of-pocket expenses of this offering, excluding underwriting discounts and commissions, will be approximately $          .

       We have agreed to indemnify the underwriters against certain liabilities including liabilities under the Securities Act.

OUR COMPANY

      We are a publicly traded limited partnership that was formed in April 1998 to acquire, own, and operate all of the NGL processing and distribution assets of EPCO, Inc., or EPCO, formerly known as Enterprise Products Company. We conduct all of our business through our 100% owned subsidiary, Enterprise Products Operating L.P. (our “Operating Partnership”) and its subsidiaries and joint ventures. Our general partner, Enterprise Products GP, LLC, owns a 2% interest in us.

      We are a leading North American midstream energy company that provides a wide range of services to producers and consumers of natural gas, natural gas liquids, or NGLs, and crude oil, and we are an industry leader in the development of midstream infrastructure in the deepwater trend of the Gulf of Mexico. We have the only integrated North American midstream network, which includes natural gas transportation, gathering, processing and storage; NGL fractionation (or separation), transportation, storage and import and export terminalling; and crude oil transportation and offshore production platform services. Our midstream network links producers of natural gas, NGLs and crude oil from the largest supply basins in the United States, Canada and the Gulf of Mexico with the largest consumers and international markets. NGLs are used by the petrochemical and refining industries to produce plastics, motor gasoline and other industrial and consumer products and also are used as residential, agricultural and industrial fuels. We provide integrated services to our customers and generate fee-based cash flow from multiple sources along our midstream energy “value chain.”

      Our midstream energy services include:

      In addition to our current strategic position in the Gulf of Mexico, we have access to major natural gas and NGL supply basins throughout the United States and Canada, including the Rocky Mountains, the San Juan and Permian basins, the Mid-Continent region and, through third-party pipeline connections, north into Canada’s Western Sedimentary basin. Our system of assets in the Gulf Coast region of the

United States, combined with our Mid-America and Seminole pipeline systems, create the only integrated North American midstream network.

      Certain of our facilities are owned jointly by us and other industry partners, either through co-ownership arrangements or joint ventures. Some of our jointly owned facilities are operated by other owners.

      We do not have any employees. All of our management, administrative and operating functions are performed by employees of EPCO, our ultimate parent company, pursuant to the Administrative Services Agreement. For a discussion of the Administrative Services Agreement, please read Item 13 of our latest Annual Report on Form 10-K.

      Our principal executive offices are located at 2727 North Loop West, Houston, Texas 77008-1038, and our telephone number is (713) 880-6500.

RISK FACTORS

      An investment in our securities involves risks. You should consider carefully the following risk factors, together with all of the other information included in, or incorporated by reference into, this prospectus and any prospectus supplement in evaluating an investment in our securities. This prospectus also contains forward-looking statements that involve risks and uncertainties. Please read “Forward-Looking Statements.” Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including the risks described below and the other information included in, or incorporated by reference into, this prospectus. If any of these risks occur, our business, financial condition or results of operations could be adversely affected.

Risks Related to Our Business

      We operate predominantly in the midstream energy sector which includes gathering, transporting, processing, fractionating and storing natural gas, NGLs and crude oil. As such, our results of operations, cash flows and financial condition may be materially adversely affected by changes in the prices of these hydrocarbon products and by changes in the relative price levels among these hydrocarbon products. In general terms, the prices of natural gas, NGLs, crude oil and other hydrocarbon products are subject to fluctuations in response to changes in supply, market uncertainty and a variety of additional factors that are impossible to control. These factors include:

      We are also exposed to natural gas and NGL commodity price risk under natural gas processing and gathering and NGL fractionation contracts that provide for our fee to be calculated based on a regional natural gas or NGL price index or to be paid in-kind by taking title to natural gas or NGLs. A decrease in natural gas and NGL prices can result in lower margins from these contracts, which may materially adversely affect our results of operations, cash flows and financial position.

      Our profitability could be materially impacted by a decline in the volume of natural gas, NGLs and crude oil transported, gathered or processed at our facilities. A material decrease in natural gas or crude oil production or crude oil refining, as a result of depressed commodity prices, a decrease in exploration and development activities or otherwise, could result in a decline in the volume of natural gas, NGLs and crude oil handled by our facilities.

      The crude oil, natural gas and NGLs available to our facilities will be derived from reserves produced from existing wells, which reserves naturally decline over time. To offset this natural decline, our facilities will need access to additional reserves. Additionally, some of our facilities will be dependent on reserves that are expected to be produced from newly discovered properties that are currently being developed.

      Exploration and development of new oil and natural gas reserves is capital intensive, particularly offshore in the Gulf of Mexico. Many economic and business factors are out of our control and can adversely affect the decision by producers to explore for and develop new reserves. These factors could include relatively low oil and natural gas prices, cost and availability of equipment, regulatory changes, capital budget limitations or the lack of available capital. For example, a sustained decline in the price of natural gas and crude oil could result in a decrease in natural gas and crude oil exploration and development activities in the regions where our facilities are located. This could result in a decrease in volumes to our offshore platforms, natural gas processing plants, natural gas, crude oil and NGL pipelines, and NGL fractionators which would have a material adverse affect on our results of operations, cash flows and financial position. Additional reserves, if discovered, may not be developed in the near future or at all.

      A reduction in demand for NGL products by the petrochemical, refining or heating industries, whether because of general economic conditions, reduced demand by consumers for the end products made with NGL products, increased competition from petroleum-based products due to pricing differences, adverse weather conditions, government regulations affecting prices and production levels of natural gas or the content of motor gasoline or other reasons, could materially adversely affect our results of operations, cash flows and financial position. For example:

      Ethane. If natural gas prices increase significantly in relation to ethane prices, it may be more profitable for natural gas producers to leave the ethane in the natural gas stream to be burned as fuel than to extract the ethane from the mixed NGL stream for sale.

      Propane. The demand for propane as a heating fuel is significantly affected by weather conditions. Unusually warm winters could cause the demand for propane to decline significantly and could cause a significant decline in the volumes of propane that the combined company transports.

      Isobutane. Any reduction in demand for motor gasoline additives may reduce demand for isobutane. During periods in which the difference in market prices between isobutane and normal butane is low or inventory values are high relative to current prices for normal butane or isobutane, our operating margin from selling isobutane could be reduced.

      Propylene. Any downturn in the domestic or international economy could cause reduced demand for propylene, which could cause a reduction in the volumes of propylene that we produce and expose our investment in inventories of propane/ propylene mix to pricing risk due to requirements for short-term price discounts in the spot or short-term propylene markets.

      Even if reserves exist in the areas accessed by our facilities and are ultimately produced, we may not be chosen by the producers in these areas to gather, transport, process, fractionate, store or otherwise handle the hydrocarbons that are produced. We compete with others, including producers of oil and natural gas, for any such production on the basis of many factors, including:

      As of December 31, 2004, we had approximately $4.3 billion of consolidated debt outstanding. The amount of our debt could have significant effects on our future operations, including, among other things:
