                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE 1.  ORGANIZATION AND BASIS OF PRESENTATION

         TEPPCO Partners, L.P. is a Delaware limited partnership which operates
through TE Products Pipeline Company, Limited Partnership, a Delaware limited
partnership (collectively the "Partnership"), in which TEPPCO Partners, L.P.
holds a 99% interest as the sole limited partner. Texas Eastern Products
Pipeline Company, (the "Company") is the general partner of the Partnership and
has agreed not to voluntarily withdraw as the general partner of the
Partnership, subject to certain limited exceptions, prior to January 1, 2000. On
June 18, 1997, PanEnergy Corp and Duke Power Company completed a previously
announced merger. At closing, the combined companies became Duke Energy
Corporation ("Duke Energy"). The Company, previously a wholly-owned subsidiary
of PanEnergy Corp, became an indirect wholly-owned 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 September 30, 1997, and the results of operations and cash
flows for the periods presented. The results of operations for the nine months
ended September 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 September 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 7.73% and 6.35% of net income for the nine months ended
September 30, 1997 and 1996, respectively.

NOTE 2.  ACCOUNTING POLICY CHANGE

         In February 1997, the Financial Accounting Standards Board ("FASB")
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.

         In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive
Income." This statement establishes standards for reporting and display of
comprehensive income and its components in a full set of financial statements.
In June 1997, the FASB also issued SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement establishes standards for
reporting information about operating segments in annual financial statements
and requires that enterprises report selected information about operating
segments in interim reports issued to shareholders. Both of these statements are
effective for financial statements for periods beginning after December 15,
1997. As both SFAS 130 and 131 establish standards for reporting and display,
the Partnership does not expect the adoption of these statements to have a
material impact on its financial condition or results of operations.

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
September 30, 1997, short-term investments included $8.2 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 September 30, 1997, and are classified
as held-to-maturity securities.

LONG-TERM INVESTMENTS

         At September 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 September 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 September 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 "First Mortgage
Notes"). The First Mortgage 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 First
Mortgage Notes. On March 7, 1997, the Partnership paid $13.0 million for current
maturities due on the First Mortgage Notes. At September 30, 1997, the current
maturities of the First Mortgage Notes were $17.0 million, which are payable on
March 6, 1998.

         The agreements relating to the First Mortgage 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):

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 First Mortgage
Notes.

         On August 8, 1997, the Partnership paid the second quarter cash
distribution of $0.80 per Unit to Unitholders of record on July 31, 1997.
Additionally, on October 17, 1997, the Partnership declared a cash distribution
of $0.80 per Unit for the quarter ended September 30, 1997. The third quarter
distribution was paid on November 7, 1997, to Unitholders of record on October
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 nine months ended September 30,
1997 and 1996, incentive distributions paid to the Company totaled $2.3 million
and $1.6 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 groundwater contamination
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. In November 1997, IDEM
approved the final remedial investigation report for the Seymour terminal. The
Partnership is currently negotiating with IDEM the clean-up levels to be
attained at 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 September 30, 1997,
The Partnership had approximately 20.8 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.

NOTE 8.  SUBSEQUENT EVENT

         On October 22, 1997, TE Products Pipeline Company, Limited Partnership
filed a Registration Statement on Form S-3 under the Securities Act of 1933 for
the registration of $150 million principal amount of Senior Notes due 2007 and
$240 million principal amount of Senior Notes due 2027 (collectively the
"Notes"). The net proceeds from the sale of the Notes, estimated to be
approximately $387 million, will be used to repay the First Mortgage Notes of
approximately $327 million, together with a redemption premium thereon currently
estimated at approximately $60 million. The precise amount of the redemption
premium will depend upon U. S. Treasury interest rates in effect on the day
prior to the redemption of the First Mortgage Notes. The closing of the Notes
and the redemption of the First Mortgage Notes are expected to occur
simultaneously.

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

GENERAL

         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 Northeast for propane, a major fuel for residential heating.

         The Partnership's revenues are derived from the transportation of
refined products and LPGs, the storage and short-haul shuttle transportation of
LPGs at the Mont Belvieu, Texas complex, sale of product inventory and other
ancillary services. Labor and electric power costs comprise the two largest
operating expense items of the Partnership.

         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

         Net income for the quarter ended September 30, 1997 was $11.4 million,
compared with net income of $10.4 million for the 1996 third quarter. The
increase in net income resulted from a $3.8 million increase in operating
revenues and a $0.3 million decrease in interest expense. These increases were
partially offset by a $1.8 million increase in costs and expenses and a $1.1
million decrease in other income.

         Net income for the nine months ended September 30, 1997 increased $1.6
million to $42.4 million, compared with net income of $40.8 million for the nine
months ended September 30, 1996, due primarily to a $4.1 million increase in
operating revenues, a $0.9 million decrease in interest expense and a $0.5
million increase in interest costs capitalized, partially offset by a $1.6
million increase in costs and expenses and a $2.2 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 $1.7 million for the
quarter ended September 30, 1997, compared with the prior year quarter, as a
result of higher deliveries of natural gasoline and methyl tertiary butyl ether
("MTBE"), higher tariff rates on the Ark-La-Tex system and higher tariff rates
on barrels originating from the pipeline connection with Colonial Pipeline
Company's ("Colonial") pipeline at Beaumont, Texas. The increase in natural
gasoline deliveries was attributable to higher feedstock and blending demand in
the Midwest due to increased gasoline production in that region. The increase in
MTBE deliveries was due primarily to higher short-haul deliveries at the
Partnership's marine terminal near Beaumont, Texas. Additionally, approximately
$0.2 million of revenue was recognized on previously deferred deficit
transportation payments for MTBE deliveries in the Midwest. Deliveries of motor
fuel decreased, as compared to the third quarter of 1996, as a result of
increased refinery utilization rates in the Midwest, refinery production
problems along the upper Texas Gulf Coast and more favorable economics for Gulf
Coast produced gasoline to be transported to other regions of the United States
not supplied by the Partnership's pipeline system. The increase in tariff rates
on the Ark-La-Tex system was due to new tariff structures for volumes
transported on the expanded portion between Shreveport, Louisiana, and El
Dorado, Arkansas, which was placed in service on March 31, 1997.

         LPGs transportation revenues increased slightly during the 1997 third
quarter, compared with the prior year third quarter, as a result of higher
butane deliveries due primarily to a Northeast area refinery, which was shut
down throughout 1996, resuming operations during the second quarter of 1997, and
increased demand for propane in the Midwest. These increases were partially
offset by lower propane deliveries in the Northeast due to higher amounts of
Canadian imports in that market area. The decrease in the LPGs transportation
average tariff rate per barrel resulted from the lower percentage of long-haul
propane deliveries.

         For the nine months ended September 30, 1997, refined products
transportation revenues increased $6.1 million, compared with the corresponding
period in 1996, due to a 4% increase in volumes delivered and a 3% increase in
the refined products average tariff per barrel. The increase in refined products
transportation volumes was attributable to increased feedstock and blending
demand for natural gasoline in the Midwest, the full period impact in 1997 of
the pipeline connection at the Little Rock Air Force Base, which was completed
in June 1996, and increased MTBE deliveries at the marine terminal near
Beaumont, Texas. Additionally, higher revenues were generated from the
Ark-La-Tex system expansion and the pipeline connection with Colonial. These
increases were partially offset by lower motor fuel and distillate deliveries
due to higher refinery utilization rates in the Midwest during 1997.

         LPGs transportation revenues decreased $1.8 million during the nine
months ended September 30, 1997, compared with the same period in 1996, due to a
4% decrease in the LPGs average tariff per barrel, partially offset by a 1%
increase in LPGs volumes delivered. Long-haul propane deliveries were lower than
the prior year because of warmer winter weather in the Northeast during the
first quarter of 1997. Increased Canadian imports of propane in the Northeast
and butane in the Midwest market areas also resulted in decreased volumes
delivered in 1997. These decreases were partially offset by stronger demand for
butane and 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. Increased propane demand along the upper Texas Gulf Coast
resulted in a 33% increase in short-haul propane deliveries. The 4% decrease in
the LPGs average tariff per barrel resulted from the higher percentage of
short-haul propane deliveries during 1997.

         Revenues generated from Mont Belvieu operations increased $1.0 million
during the quarter and nine months ended September 30, 1997, compared with the
corresponding periods in 1996, due primarily to higher terminaling fees on
butane received into the system, increased propane dehydration fees and higher
petrochemical demand for LPGs along the upper Texas Gulf Coast. The decrease in
the Mont Belvieu operations average tariff per barrel for the nine months ended
September 30, 1997, compared with the prior year, was due to a higher percentage
of contract deliveries in 1997, which generally carry lower tariffs.

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

         RESULTS OF OPERATIONS - (CONTINUED)


         Gains on the sale of inventory decreased $1.4 million during the nine
months ended September 30, 1997, compared with the corresponding period in 1996,
as a result of lower volumes of gasoline being sold during 1997.

         Other operating revenues increased $0.9 million during the 1997 third
quarter, as compared to the same period in 1996, due primarily to revenue
recognition of deficiency volumes on butane storage contracts and increased
terminaling revenues, partially offset by lower refined products storage
revenue.

         During the nine months ended September 30, 1997, other operating
revenues increased slightly due to the factors noted above, being offset by
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, during the first quarter of 1997.

         Costs and expenses increased $1.8 million during the third quarter of
1997, compared with the prior year, due primarily to a $1.2 million increase in
operating, general and administrative expenses and a $0.5 million increase in
taxes - other than income taxes. The increase in operating, general and
administrative expenses resulted primarily from increased throughput-related
power costs, expenses recorded for environmental remediation at the
Partnership's Seymour, Indiana, terminal, rental expense associated with the
capacity lease with Colonial, which began in May 1997, and increased labor and
benefits costs. These increases were partially offset by a reduction of expense
related to the settlement of insurance claims for previously incurred
environmental litigation costs. The increase in taxes - other than income taxes
resulted from a credit recorded during the third quarter of 1996 due to 1995 ad
valorem taxes being lower than estimated.

         Costs and expenses increased $1.6 million during the first nine months
of 1997, compared with the same period in 1996, due primarily to a $0.9 million
increase in operating, general and administrative expenses and a $0.8 million
increase in taxes - other than income taxes. The increase in operating, general
and administrative expenses was primarily attributable to throughput-related
expenses and rental expense of the Colonial capacity lease, partially offset by
the insurance settlement during the third quarter of 1997, lower outside service
costs for system maintenance and lower product measurement losses. The increase
in taxes - other than income taxes was due to higher ad valorem tax assessments
in 1997 and the credit for ad valorem taxes recorded during the third quarter of
1996.

         Interest expense decreased during both the quarter and nine-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 $0.5 million during
the nine month period ended September 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 - net decreased during both the quarter and nine months
ended September 30, 1997, compared with the corresponding periods in 1996, due
primarily to lower interest income attributable to lower cash balances during
1997. Additionally, during the third quarter of 1997, a loss of $0.5 million was
recorded on the sale of the Partnership's Arkansas City, Arkansas, terminal.

FINANCIAL CONDITION AND LIQUIDITY

         Net cash from operations totaled $51.0 million for the nine-month
period ended September 30, 1997, compared with $54.2 million for the
corresponding period in 1996. The decrease resulted from a $4.6 million increase
in working capital uses of cash, partially offset by a $1.5 million increase in
income before charges for depreciation and amortization. The increase in working
capital uses of cash resulted primarily from a receivable

                                       11
<PAGE>   12


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

FINANCIAL CONDITION AND LIQUIDITY - (CONTINUED)

related to insurance claims settled in September 1997, lower trade accounts
receivable balances during 1997 and lower inventory sales during 1997, which
were partially offset by lower cash payments for accrued expenses during 1997.
Additionally, net cash from operations for the nine months ended September 30,
1997 and 1996 reflect semi-annual interest payments related to the First
Mortgage Notes of $33.6 million and $34.7 million, respectively.

         Cash flows used in investing activities during the first nine months of
1997 included $24.5 million of capital expenditures and $3.9 million of
additional cash investments, partially offset by $18.0 million from investment
maturities, $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 and $1.4 million
from the proceeds of the sale of the Arkansas City terminal. Cash flows used in
investing activities during the first nine months of 1996 included $29.4 million
of capital expenditures and additional investments of $14.4 million, partially
offset by matured investments of $10.9 million. Capital expenditures are
expected to total approximately $34 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.

         The Partnership paid cash distributions of $36.3 million during the
nine months ended September 30, 1997. Additionally, on October 17, 1997, the
Partnership declared a cash distribution of $0.80 per Unit for the three months
ended September 30, 1997. The third quarter cash distribution was paid on
November 7, 1997 to Unitholders of record on October 31, 1997.

         The First Mortgage 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 First Mortgage Notes on March 7, 1997.
At September 30, 1997, the current maturities of the First Mortgage Notes were
$17.0 million. The note agreement relating to the First Mortgage 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 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 groundwater
contamination 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. In November
1997, IDEM approved the final remedial investigation report for the Seymour

terminal. The Partnership is currently negotiating with IDEM the clean-up levels
to be attained at 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.

         On October 22, 1997, TE Products Pipeline Company, Limited Partnership
filed a Registration Statement on Form S-3 under the Securities Act of 1933 for
the registration of $150 million principal amount of Senior Notes due 2007 and
$240 million principal amount of Senior Notes due 2027 (collectively the
"Notes"). The net proceeds from the sale of the Notes, estimated to be
approximately $387 million, will be used to repay the First Mortgage Notes of
approximately $327 million, together with a redemption premium thereon currently
estimated at approximately $60 million. The precise amount of the redemption
premium will depend upon U. S. Treasury interest rates in effect on the day
prior to the redemption of the First Mortgage Notes. The closing of the Notes
and the redemption of the First Mortgage Notes are expected to occur
simultaneously.

         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.
