subsidiary of Duke Energy on the date of the merger.

     The accompanying unaudited consolidated financial statements reflect all
adjustments, which are, in the opinion of management, of a normal and recurring
nature and necessary for a fair statement of the financial position of the
Partnership as of June 30, 1997, and the results of operations and cash flows
for the periods presented. The results of operations for the six months ended
June 30, 1997, are not necessarily indicative of results of operations for the
full year 1997. The interim financial statements should be read in conjunction
with the Partnership's consolidated financial statements and notes thereto
presented in the TEPPCO Partners, L.P. Annual Report on Form 10-K for the year
ended December 31, 1996.

     Net income per Unit is computed by dividing net income, after deduction of
the general partner's interest, by the weighted average number of Units
outstanding (a total of 14,500,000 Units as of June 30, 1997). The general
partner's percentage interest in net income is based on its percentage of cash
distributions from Available Cash for each period (see Note 6). The general
partner was allocated 6.72% and 5.15% of net income for the six months ended
June 30, 1997 and 1996, respectively.

NOTE 2. ACCOUNTING POLICY CHANGE

     In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards (SFAS) 128, "Earnings per Share."
This statement establishes standards for computing and presenting net income
per Unit and requires, among other things, dual presentation of basic and
diluted net income per Unit on the face of the consolidated statements of
income. This statement is effective for financial statements for periods ending
after December 15, 1997. The Partnership will adopt SFAS 128 by December 31,
1997, and does not expect the adoption to have a material impact on its
calculation of net income per Unit.

NOTE 3. INVESTMENTS

SHORT-TERM INVESTMENTS

     The Partnership routinely invests cash in liquid short-term investments as
part of its cash management program. Investments with maturities at date of
purchase of 90 days or less are considered cash and cash equivalents. At June
30, 1997, short-term investments included $10.2 million of investment-grade
medium-term corporate debt securities, which mature within one year. All
short-term investments are stated at amortized cost, which approximates the
aggregate fair value at June 30, 1997, and are classified as held-to-maturity
securities.

                                  (UNAUDITED)


LONG-TERM INVESTMENTS

     At June 30, 1997, the Partnership had $8.7 million invested in
investment-grade medium-term corporate debt securities, which have varying
maturities from 1999 through 2001. These securities are classified as
held-to-maturity securities and are stated at amortized cost. At June 30, 1997,
the aggregate fair value and unrealized gain for these securities was $8.8
million and $0.1 million, respectively. Such investments included a $0.9
million investment in Duke Power Company corporate notes as of June 30, 1997.

NOTE 4. FIRST MORTGAGE NOTES

     In connection with its formation, TE Products Pipeline Company, Limited
Partnership issued 9.60% Series A First Mortgage Notes, due 2000, and 10.20%
Series B First Mortgage Notes, due 2010 (collectively the "Notes"). The
Notes, which are secured by a mortgage on substantially all property, plant and
equipment of the Partnership, have mandatory annual prepayments at par through
March 7, 2010. Interest is payable semiannually on each March 7 and September 7
until retirement of the Notes. On March 7, 1997, the Partnership paid $13.0
million for current maturities due on the Notes. At June 30, 1997, the current
maturities of the Notes were $17.0 million, which are payable on March 6, 1998.

     The agreements relating to the Notes contain certain covenant
restrictions, including limitations on cash distributions and on the amount of
future indebtedness, none of which is expected to have a material adverse
effect on the Partnership's operations.

NOTE 5. INVENTORIES

     Inventories are carried at the lower of cost (based on weighted average
cost method) or market. The major components of inventories were as follows (in
thousands):

     The costs of inventories were lower than market at June 30, 1997, and
December 31, 1996.

NOTE 6. CASH DISTRIBUTIONS

     The Partnership makes quarterly cash distributions of all of its Available
Cash, generally defined as consolidated cash receipts less consolidated cash
disbursements and cash reserves established by the general partner in its sole
discretion or as required by the terms of the Notes.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                                  (UNAUDITED)



     On May 9, 1997, the Partnership paid the first quarter cash distribution
of $0.75 per Unit to Unitholders of record on April 30, 1997. Additionally, on
July 14, 1997, the Partnership declared a cash distribution of $0.80 per Unit
for the quarter ended June 30, 1997, which represents an increase of $0.05 per
Unit in the quarterly distribution. The second quarter distribution is payable
on August 8, 1997, to Unitholders of record on July 31, 1997.

     The Company receives incremental incentive distributions of 15%, 25% and
50% on quarterly distributions of Available Cash that exceed $0.55, $0.65 and
$0.90 per Unit, respectively. During the six months ended June 30, 1997 and
1996, incentive distributions paid to the Company totaled $1.4 million and $0.9
million, respectively.

NOTE 7. COMMITMENTS AND CONTINGENCIES

     The Partnership is involved in various claims and legal proceedings
incidental to its business. In the opinion of management, these claims and
legal proceedings will not have a material adverse effect on the Partnership's
consolidated financial position or results of operations.

     The operations of the Partnership are subject to federal, state and local
laws and regulations relating to protection of the environment. Although the
Partnership believes the operations of the pipeline system are in material
compliance with applicable environmental regulations, risks of significant
costs and liabilities are inherent in pipeline operations, and there can be no
assurance that significant costs and liabilities will not be incurred.
Moreover, it is possible that other developments, such as increasingly strict
environmental laws and regulations and enforcement policies thereunder, and
claims for damages to property or persons resulting from the operations of the
pipeline system, could result in substantial costs and liabilities to the
Partnership. The Partnership does not anticipate that changes in environmental
laws and regulations will have a material adverse effect on its financial
position, operations or cash flows in the near term.

     The Partnership and the Indiana Department of Environmental Management
(IDEM) have entered into an Agreed Order that will ultimately result in a
remediation program for any on-site and off-site environmental problems
attributable to the Partnership's operations at the Seymour, Indiana, terminal.
As part of the Agreed Order, the Partnership has completed the remedial
investigation sampling for groundwater contamination and has submitted to IDEM
the final remedial investigation report for the Seymour terminal. In the
opinion of the general partner, the completion of the remediation program to be
proposed by the Partnership, if such program is approved by IDEM, will not have
a material adverse impact on the Partnership.

     Substantially all of the petroleum products transported and stored by the
Partnership are owned by the Partnership's customers. At June 30, 1997, The
Partnership had approximately 16.9 million barrels of products in its custody
owned by customers. The Partnership is obligated for the transportation,
storage and delivery of such products on behalf of its customers. The
Partnership maintains insurance adequate to cover product losses through
circumstances beyond its control.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

        The following information is provided to facilitate increased
understanding of the 1997 and 1996 interim consolidated financial statements
and accompanying notes presented in Item 1. Material period-to-period variances
in the consolidated statements of income are discussed under "Results of
Operations." The "Financial Condition and Liquidity" section analyzes cash
flows and financial position. Discussion included in "Other Matters" addresses
key trends, future plans and contingencies. Throughout these discussions,
management addresses items that are reasonably likely to materially affect
future liquidity or earnings.

RESULTS OF OPERATIONS

        The Partnership's operations consist of the transportation, storage and
terminaling of refined petroleum products and liquefied petroleum gases (LPGs).
Operations are somewhat seasonal with higher revenues generally realized during
the first and fourth quarters of each year. Refined products volumes are
generally higher during the second and third quarters because of greater demand
for gasolines during the spring and summer driving seasons. LPGs volumes are
generally higher from November through March due to higher demand in the
Midwest and Northeast for propane, a major fuel for residential heating, and
higher demand for butane, an additive for gasoline blending.

        Net income for the quarter ended June 30, 1997 was $13.1 million,
compared with net income of $10.3 million for the 1996 second quarter. The
increase in net income resulted from a $3.7 million increase in operating
revenues and a $0.3 million decrease in interest expense. These increases were
partially offset by a $0.7 million increase in costs and expenses and a $0.6
million decrease in other income.

        Net income for the six months ended June 30, 1997 increased $0.5
million to $30.9 million, compared with net income of $30.4 million for the six
months ended June 30, 1996, due primarily to a $0.3 million increase in
operating revenues, a $0.6 million decrease in interest expense and a $0.6
million increase in interest costs capitalized, partially offset by a $1.1
million decrease in other income. See discussion below of factors affecting net
income for the comparative periods.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS 

RESULTS OF OPERATIONS - (CONTINUED)

        Refined products transportation revenues increased $4.6 million for the
quarter ended June 30, 1997, compared with the prior-year quarter, as a result
of higher deliveries of motor fuel, distillate, natural gasoline and jet fuel.
The increase in refined products transportation revenue reflects the
utilization of increased delivery capacity from the expansion of the Ark-La-Tex
system between Shreveport, Louisiana, and El Dorado, Arkansas, which was placed
in service on March 31, 1997, and the connection of the pipeline system to
Colonial Pipeline Company's (Colonial) pipeline at Beaumont, Texas.
Additionally, jet fuel volumes increased as a result of the pipeline connection
at the Little Rock Air Force base, which was completed in June 1996. Natural
gasoline deliveries increased primarily from favorable blending economics in
Midwest market areas. The increase in the refined products average tariff per
barrel reflects an increase in the percentage of long-haul deliveries as well
as higher tariff rates on the Ark-La-Tex system.

        LPGs transportation revenues increased $1.3 million for the quarter
ended June 30, 1997, compared with the second quarter of 1996, due primarily to
increased propane deliveries in the upper Midwest and Northeast attributable to
colder weather continuing into the second quarter of 1997, favorable price
differentials and lower competing local supply in the Northeast. Additionally,
isobutane transportation revenue increased from the prior year quarter due to
the resumption during the second quarter of 1997 of operations at a Northeast
refinery that was shut down throughout 1996. The 2% increase in the LPGs
average tariff per barrel resulted from the higher percentage of long-haul
propane and isobutane deliveries to the Northeast.

        For the six months ended June 30, 1997, refined products transportation
revenues increased $4.4 million, compared with the corresponding period in
1996, due to a 5% increase in volumes delivered and a 4% increase in the
refined products average tariff per barrel. The increase in refined products
transportation volumes was attributable to the factors discussed above during
the second quarter of 1997, partially offset by lower deliveries of motor fuel
and distillates during the first quarter of 1997 due to increased refinery
utilization in the Midwest market areas and lower refinery production along the
upper Texas Gulf Coast. The increase in the refined products average tariff per
barrel during 1997 reflects a higher percentage of long-haul transportation
deliveries and the higher tariff rate on the Ark-La-Tex system.

        LPGs transportation revenues decreased $1.8 million during the six
months ended June 30, 1997, compared with the same period in 1996, due
primarily to lower propane deliveries attributable to warmer winter weather in
the first quarter of 1997, and a decrease in butane deliveries as a result of
increased competing product being imported from Canada into the Midwest. These
decreases were partially offset by favorable price differentials of propane in
the Northeast market area during the second quarter of 1997, and stronger
demand for isobutane as a refinery feedstock due to the resumption during the
second quarter of 1997 of operations at a Northeast refinery that was shut down
throughout 1996. The 4% decrease in the LPGs average tariff per barrel resulted
from lower long-haul propane deliveries during the first quarter of 1997, as
well as increased demand for short-haul deliveries along the upper Texas Gulf
Coast.

        Revenues generated from Mont Belvieu operations increased slightly
during both the quarter and six months ended June 30, 1997, compared with the
corresponding periods in 1996, due primarily to higher terminaling fees on
butane received into the system and higher petrochemical demand along the upper
Texas Gulf Coast. These increases were largely offset by the decrease in the
Mont Belvieu operations average tariff per barrel for shuttle deliveries during
1997, which resulted from higher contract deliveries, which generally carry
lower tariffs.

        Gains on the sale of inventory decreased during both the quarter and
six months ended June 30, 1997, compared with the corresponding periods in
1996, as a result of lower volumes of gasoline being sold during the second
quarter of 1997.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

RESULTS OF OPERATIONS - (CONTINUED)

        Other operating revenues decreased during both the quarter and six
months ended June 30, 1997, as compared to the corresponding periods in 1996,
due to write downs of product inventory recorded during the second quarter of
1997 and lower propane imports received at the marine terminal at Providence,
Rhode Island, due primarily to warmer winter weather during the first quarter
of 1997. These decreases were partially offset by higher refined products
terminaling fees attributable to the increase in refined products
transportation volumes delivered in 1997.

        Costs and expenses increased $0.7 million during the second quarter of
1997, compared with the prior year, due to a $0.5 million increase in
operating, general and administrative expenses and a $0.2 million increase in
taxes - other than income taxes. The increase in operating, general and
administrative expenses resulted primarily from increased rental expense
associated with the capacity lease with Colonial, which began in May 1997, and
increased throughput-related costs and labor costs. These increases were
partially offset by lower environmental remediation expenses and lower product
measurement losses. The increase in taxes - other than income taxes resulted
from higher property tax assessments.

        Costs and expenses decreased slightly during the first six months of
1997, compared with the same period in 1996, due primarily to lower operating,
general and administrative expenses attributable to lower outside services for
system maintenance and remediation and lower product measurement losses. These
decreases were partially offset by increased thoughput-related costs, increased
labor and benefits expenses and the Colonial capacity lease. Lower operating,
general and administrative expenses were partially offset by higher property
tax assessments for 1997.

        Interest expense decreased during both the quarter and six-month
periods in 1997, compared with the same periods in 1996, due to principal
payments on the First Mortgage Notes of $10.0 million and $13.0 million in
March 1996 and 1997, respectively. Capitalized interest increased $0.6 million
during the six month period ended June 30, 1997, compared with the same period
in 1996 as a result of higher construction balances related to capital
projects, which commenced during 1996, and were completed during 1997. Other
income, primarily interest, decreased during both the quarter and six months
ended June 30, 1997, compared with the corresponding periods in 1996, as a
result of lower cash balances in 1997.

FINANCIAL CONDITION AND LIQUIDITY

        Net cash from operations totaled $40.5 million for the six-month period
ended June 30, 1997, compared with $47.5 million for the corresponding period
in 1996. The decrease resulted primarily from a decrease in working capital
sources of cash. The decrease in working capital sources of cash was primarily
due to higher accounts receivable balances related to increased operating
revenues during the second quarter of 1997 and lower inventory sales during
1997, partially offset by lower cash payments for accrued expenses during 1997.
Net cash from operations for the six months ended June 30, 1997 and 1996
reflect semi-annual interest payments related to the Notes of $17.1 million and
$17.6 million, respectively.

        Cash flows used in investing activities during the first six months of
1997 included $15.4 million of capital expenditures and $3.9 million of
additional cash investments, partially offset by $16.0 million from investment
maturities and $1.0 million of insurance proceeds related to the replacement
value of a 20-inch diameter auxiliary pipeline at the Red River in central
Louisiana, which was damaged in 1994 and subsequently removed from service.
Cash flows used in investing activities during the first six months of 1996
included $15.6 million of capital expenditures and additional investments of
$14.4 million, partially offset by matured investments of $9.9 million. Capital
expenditures are expected to total approximately $35 million for the full year
of 1997. The Partnership revises capital spending periodically in response to
changes in cash flows and operations. Interest income earned on all investments
is included in cash from operations.

Item 2. Management's Discussion and Analysis of Financial Condition and
        Results of Operations

Financial Condition and Liquidity - (Continued)

        The Partnership paid cash distributions of $23.6 million during the six
months ended June 30, 1997. Additionally, on July 14, 1997, the Partnership
declared a cash distribution of $0.80 per Unit for the three months ended June
30, 1997, increasing the annualized distribution to $3.20 per Unit from $3.00
per Unit. The second quarter cash distribution is payable on August 8, 1997 to
Unitholders of record on July 31, 1997.

        The Notes, which are secured by a mortgage on substantially all
property, plant and equipment of the Partnership, require annual principal
payments through March 2010. Interest is payable semi-annually on March 7 and
September 7. Cash and cash equivalents were reduced by the $13.0 million
principal payment related to the Notes on March 7, 1997. At June 30, 1997, the
current maturities of the Notes were $17.0 million. The note agreement relating
to the Notes limits the amount of cash distributions that can be made by TE
Products Pipeline Company, Limited Partnership to TEPPCO Partners, L.P. Such
restriction is not anticipated to preclude the Partnership from making
quarterly distributions to Unitholders of at least $0.80 per Unit during the
remainder of 1997.

OTHER MATTERS

        The operations of the Partnership are subject to federal, state and
local laws and regulations relating to protection of the environment. Although
the Partnership believes the operations of the pipeline system are in material
compliance with applicable environmental regulations, risks of significant
costs and liabilities are inherent in pipeline operations, and there can be no
assurance that significant costs and liabilities will not be incurred.
Moreover, it is possible that other developments, such as increasingly strict
environmental laws and regulations and enforcement policies thereunder, and
claims for damages to property or persons resulting from the operations of the
pipeline system could result in substantial costs and liabilities to the
Partnership.

        The Partnership and the Indiana Department of Environmental Management
(IDEM) have entered into an Agreed Order that will ultimately result in a
remediation program for any on-site and off-site environmental problems
attributable to the Partnership's operations at the Seymour, Indiana, terminal.
As part of the Agreed Order, the Partnership has completed the remedial
investigation sampling for groundwater contamination and has submitted to IDEM
the final remedial investigation report for the Seymour terminal. In the
opinion of the general partner, the completion of the remediation program to be
proposed by the Partnership, if such program is approved by IDEM, will not have
a material adverse impact on the Partnership

        During June 1997, the Partnership filed rate increases on selective
refined products tariffs and LPGs tariffs, averaging 1.7%. These rate increases
became effective July 1, 1997 without suspension or refund obligation.

        The matters discussed herein include forward-looking statements within
the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934 based on current management expectations that
involve risk and uncertainties which could cause actual results to differ
materially from those anticipated. For additional discussion of such risks and
uncertainties, see the Partnership's 1996 Annual Report on Form 10-K.
