| (1) The      maximum number of barrels that our NGL pipelines can transport per day      depends upon the operating balance achieved at a given point in time      between various segments of the system.  Since the operating      balance is dependent upon the mix of products to be shipped and demand      levels at various delivery points, the exact capacity of our NGL pipelines      cannot be determined.  We measure the utilization rates of our      NGL pipelines in terms of average throughput.(2) On      a weighted-average basis, aggregate utilization rates for our NGL      fractionation plants were approximately 84.3%, 82.8% and 76.7% during the      years ended December 31, 2008, 2007 and 2006,  respectively. |

| §   | The      South Texas NGL      System consists of: (i) two NGL fractionation facilities (i.e., the      Shoup and Armstrong plants); (ii) approximately 380 miles of intrastate      NGL transportation pipelines that transport mixed NGLs from various South      Texas natural gas processing facilities (primarily those owned by EPO) to      our Shoup and Armstrong fractionators; and (iii) intrastate NGL pipelines      aggregating 937 miles that deliver NGLs from the Shoup and Armstrong      fractionators to our Mont Belvieu storage complex and to other customers      along the upper Texas Gulf Coast.  We also lease two NGL storage      facilities (i.e., Markham and Almeda) that are integral components of the      South Texas NGL System. |

|    | A      major customer of our South Texas NGL System is EPO, which uses the system      to process, transport and store NGLs.  EPO accounted for 90% of      the revenues generated by the South Texas      NGL System during the year ended December 31, 2008. As      a result of the DEP I and DEP II dropdown transactions, we own a 66%      equity interest in the entities that own the assets comprising the South      Texas NGL System.  EPO owns the remaining equity interests in      theseentities. |

| §   | The      Mont Belvieu Storage complex      consists of three interconnected underground storage      facilities:  Mont Belvieu East, Mont Belvieu West and Mont      Belvieu North.  The Mont Belvieu East facility is the largest of our      three Mont Belvieu storage facilities.  This facility consists      of 13 storage caverns with an underground NGL and petrochemical storage      capacity of approximately 55 MMBbls and an above-ground brine pit      with a brine capacity of approximately 10 MMBbls.  This      facility also has two brine production wells.  The Mont Belvieu West      facility consists of 10 caverns with an underground NGL and petrochemical      storage capacity of approximately 15 MMBbls and an above-ground brine      pit with a brine capacity of approximately 2 MMBbls.  The      Mont Belvieu North facility consists of 10 caverns with an underground NGL      and petrochemical storage capacity of approximately 30 MMBbls and an      above-ground brine pit with a brine capacity of approximately      8 MMBbls. We      have initiated several projects to improve the integration of our three      Mont Belvieu storage facilities.  These projects include      additional pipelines to more efficiently connect the facilities and the      drilling of additional entry points into certain wells to increase flow      rates. |

| §   | Shell      Exchange Agreements – Shell is obligated to meet minimum delivery      requirements under the Lou-Tex Propylene and Sabine Propylene      agreements.  If Shell fails to meet such minimum delivery      requirements, it is obligated to pay a deficiency fee to      us.   The term of the Lou-Tex Propylene exchange agreement      expires in March 2020 and the term of the Sabine Propylene exchange      agreement expires in November 2011; however, both agreements will continue      on an annual basis after expiration, subject to termination by either      party.   The fees paid by Shell under the Lou-Tex Propylene      exchange agreement are generally fixed.  The fees paid by Shell      under the Sabine Propylene exchange agreement are adjusted annually based      on the operating costs of the pipeline and the U.S. Department of      Labor wage index. |

| (1) The      maximum number of barrels that our petrochemical pipelines can transport      per day depends upon the operating balance achieved at a given point in      time between various segments of the system.  Since the      operating balance is dependent upon the demand levels at various delivery      points, the exact capacity of our petrochemical pipelines cannot be      determined.  We measure the utilization rates of our      petrochemical pipelines in terms of average  throughput. |

| §   | Ethane.  Ethane is      primarily used in the petrochemical industry as feedstock for ethylene,      one of the basic building blocks for a wide range of plastics and other      chemical products.  If natural gas prices increase significantly      in relation to NGL product prices, or if the demand for ethylene falls      (and, therefore, the demand for ethane by NGL producers falls), 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 as an ethylene  feedstock. |

| §   | Propylene.  Propylene      is sold to petrochemical companies for a variety of uses, principally for      the production of polypropylene.  Propylene is subject to rapid      and material price fluctuations.  Any downturn in the domestic      or international economy could cause reduced demand for, and an oversupply      of propylene, which could cause a reduction in the volumes of propylene      that we transport. |

| §   | Neither      our partnership agreement nor any other agreement requires EPCO,      Enterprise Products Partners, Enterprise GP Holdings and TEPPCO or their      affiliates (other than our general partner) to pursue a business strategy      that favors us.  Directors and officers of EPCO and the general      partners of Enterprise Products Partners, Enterprise GP Holdings and      TEPPCO and their affiliates have a fiduciary duty to make decisions in the      best interest of their shareholders or unitholders, which may be contrary      to our interests. |

| §   | Some      of the employees of EPCO who provide services to us also may devote      significant time to the business of Enterprise Products Partners,      Enterprise GP Holdings and TEPPCO, and will be compensated by EPCO for      such services. |
|--------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | Our      partnership agreement limits the liability and reduces the fiduciary      duties of our general partner, while also restricting the remedies      available to our unitholders for actions that, without these limitations,      might constitute breaches of fiduciary duty.  By purchasing      common units, unitholders will be deemed to have consented to some actions      and conflicts of interest that might otherwise constitute a breach of      fiduciary or other duties under applicablelaw. |

| §   | EPO      or TEPPCO may propose to contribute additional assets to us and, in making      such proposal, the directors of those entities have a fiduciary duty to      their unitholders and not to ourunitholders. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | Our      partnership agreement does not restrict our general partner from causing      us to pay it or its affiliates for any services rendered on terms that are      fair and reasonable to us or entering into additional contractual      arrangements with any of these entities on our  behalf. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | Our      general partner intends to limit its liability regarding our contractual      obligations. |

| §   | Our      general partner may exercise its rights to call and purchase all of our      common units if, at any time, it and its affiliates own 80% or more of the      outstanding common units. |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | Our      general partner controls the enforcement of obligations owed to us by it      and its affiliates, including theASA. |

| §   | permits      our general partner to make a number of decisions in its individual      capacity, as opposed to in its capacity as our general      partner.  This entitles our general partner to consider only the      interests and factors that it desires, and it has no duty or obligation to      give any consideration to any interest of, or factors affecting, us, our      affiliates or any limited partner.  Examples include the      exercise of its limited call right, its rights to vote or transfer our      common units it owns, its registration rights and the determination of      whether to consent to any merger or consolidation of the partnership, or      amendment to the partnershipagreement; |

| §   | generally      provides that affiliate transactions and resolutions of conflicts of      interest not approved by the audit and conflicts committee of the board of      directors of our general partner must be on terms no less favorable to us      than those generally provided to or available from unrelated third parties      or be “fair and reasonable” to us; |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| §   | provides      that it shall be presumed that the resolution of any conflicts of interest      by our general partner or the audit, conflicts and governance committee      was not made in bad faith, and in any proceeding brought by or on behalf      of any limited partner or us, the person bringing or prosecuting such      proceeding will have the burden of overcoming such      presumption; and |

| (1) Amounts      represent discretionary annual cash awards accrued with respect to the      years presented. Cash awards are paid in February of the following      year (e.g., the cash awards for 2008 were paid in February      2009).(2) Amounts      represent expense recognized in accordance with SFAS 123(R) with respect      to restricted unit awards issued under the EPCO 1998 Plan and Employee      Partnership profits interests awards.(3) Amounts      represent expense recognized in accordance with SFAS 123(R) with respect      to unit options issued under the EPCO 1998 Plan and EPD 2008      LTIP.(4) Amounts      primarily represent (i) matching contributions under funded, qualified,      defined contribution retirement plans, (ii) quarterly distributions paid      on incentive plan awards and (iii) the imputed value of life insurance      premiums paid on behalf of the officer.(5) Mr.      Radtke served as our Chief Operating Officer until June 30, 2008, at which      time he assumed a role devoted entirely to Enterprise Products Partners’      natural gas processing business. Mr. Radtke resigned from the Company      in January 2009.(6) Mr.      Ordemann devoted a minimal amount of his time to our business activities      during 2007 and instead indirectly supervised the activities of other      personnel who were more directly involved in our affairs. As a      result, Mr. Ordemann allocated $2 thousand of his compensation to us in      2007. |       |

| (1) Amounts      presented reflect that portion of grant date fair value allocable to us      based on the percentage of time each Named Executive Officer spent on our      consolidated business activities during 2008. Based on current      allocations, we estimate that the consolidated compensation expense we      record for each Named Executive Officer with respect to these awards will      equal these amounts over time.(2) For      the period in which the restricted unit awards were outstanding during      2008, we recognized a total of $73 thousand of consolidated compensation      expense related to these awards. The remaining portion of grant date      fair value will be recognized as expense in future periods.(3) For      the period in which the unit option awards were outstanding during 2008,      we recognized a total of $14 thousand of consolidated compensation expense      related to these awards. The remaining portion of grant date fair      value will be recognized as expense in future periods.(4) For      the period in which the profits interest awards were outstanding during      2008, we recognized a total of $34 thousand of consolidated compensation      expense related to these awards. The remaining portion of grant date      fair value will be recognized as expense in futureperiods. |     |

Distributions in excess of these amounts      will be distributed 98% to Enterprise GTM and 2% to Enterprise      III.

For      example, the fixed return in 2010, assuming no other adjustments, would be      102% of 11.85%, or 12.087%. |

| (1) The      vesting date corresponds to the termination date for each Employee      Partnership. The termination date may be accelerated for change of      control and other events as described in the underlying partnership      agreements.(2) The      estimated grant date fair values were determined using a Black-Scholes      option pricing model and reflect adjustments for forfeitures, regrants and      other modifications. See following table for information regarding      the fair value assumptions.(3) Unrecognized      compensation cost represents the total future expense to be recognized by      the EPCO group of companies as of December 31, 2008. We will      recognize our allocated share of such costs in the future. The period      over which the unrecognized compensation cost will be recognized is as      follows for each Employee Partnership: 3.9 years, EPE Unit I; 5.1      years, EPE Unit II; 5.4 years, EPE Unit III; 5.1 years, Enterprise Unit;      and 4.9 years, EPCO Unit.(4) In      July 2008, the Class A preferred return was reduced from 6.25% to the      floating amounts presented. |

| §   | Level      1 fair values are based on quoted prices, which are available in active      markets for identical assets or liabilities as of the measurement      date.  Active markets are defined as those in which transactions      for identical assets or liabilities occur in sufficient frequency so as to      provide pricing information on an ongoing basis (e.g., the NYSE or the New      York Mercantile Exchange).  Level 1 primarily consists of      financial assets and liabilities such as exchange-traded financial      instruments, publicly-traded equity securities and U.S. government      treasury securities.   |

| §   | Level      2 fair values are based on pricing inputs other than quoted prices in      active markets (as reflected in Level 1 fair values) and are either      directly or indirectly observable as of the measurement      date.  Level 2 fair values include instruments that are valued      using financial models or other appropriate valuation      methodologies.  Such financial models are primarily      industry-standard models that consider various assumptions, including      quoted forward prices for commodities, time value of money, volatility      factors for stocks, and current market and contractual prices for the      underlying instruments, as well as other relevant economic      measures.  Substantially all of these assumptions are (i)      observable in the marketplace throughout the full term of the instrument,      (ii) can be derived from observable data or (iii) are validated by inputs      other than quoted prices (e.g., interest rates and yield curves at      commonly quoted intervals).  Level 2 includes      non-exchange-traded instruments such as over-the-counter forward      contracts, options and repurchase  agreements.   |

| §   | Level      3 fair values are based on unobservable inputs.  Unobservable      inputs are used to measure fair value to the extent that observable inputs      are not available, thereby allowing for situations in which there is      little, if any, market activity for the asset or liability at the      measurement date.  Unobservable inputs reflect the reporting      entity’s own ideas about the assumptions that market participants would      use in pricing an asset or liability (including assumptions about      risk).  Unobservable inputs are based on the best information      available in the circumstances, which might include the reporting entity’s      internally developed data.  The reporting entity must not ignore      information about market participant assumptions that is reasonably      available without undue cost and effort.  Level 3 inputs are      typically used in connection with internally developed valuation      methodologies where management makes its best estimate of an instrument’s      fair value.  Level 3 generally includes specialized or unique      financial instruments that are tailored to meet a customer’s specific      needs.  We had no Level 3 financial assets or liabilities at      December 31, 2008. |

| (1) The      contractual obligations presented in this table reflect 100% of our      subsidiaries obligations even though we own less than a 100% equity      interest in our operating subsidiaries.(2) See      Note 10 for additional information regarding our credit      facilities.(3) Our      estimated cash payments for interest are based on the principle amount of      consolidated debt obligations outstanding at December 31, 2008. With      respect to variable-rate debt, we applied the weighted-average interest      rates paid during 2008. See Note 10 for information regarding      variable interest rates charged in 2008 under our credit      agreements. In addition, our estimate of cash payments for interest      gives effect to interest rate swap agreements in place at December 31,      2008. See Note 6 for information regarding our financial      instruments.(4) Capital      expenditure commitments are reflected on a 100% basis before contributions      from the Parent in connection with the Omnibus Agreement and Mont Belvieu      Caverns’ limited liability company agreement (see Note14). |   |

| §   | The      timing of cash receipts from revenue transactions and cash payments for      expense transactions near the end of each reporting      period.   For example, if significant cash receipts are      posted on the last day of the current reporting period, but subsequent      payments on expense invoices are made on the first day of the next      reporting period, net cash flows provided by operating activities will      reflect an increase in the current reporting period that will be reduced      as payments are made in the next period.  We employ prudent cash      management practices and monitor our daily cash requirements to meet our      ongoing liquidity needs. |

| §   | If      commodity or other prices increase between reporting periods, changes in      accounts receivable and accounts payable and accrued expenses may appear      larger than in previous periods; however, overall levels of receivables      and payables may still reflect normal ranges.  From a      receivables standpoint, we monitor the amount of credit extended to      customers. |

| §   | Additions      to inventory for forward sales transactions or other reasons or increased      expenditures for prepaid items would be reflected as a use of cash and      reduce overall cash provided by operating activities in a given reporting      period.  As these assets are charged to expense in subsequent      periods, the expense amount is reflected as a positive change in operating      accounts; however, there is no impact on operating cash    flows. |
