                     SERVICES AND TRANSPORTATION AGREEMENT


         THIS SERVICES AND TRANSPORTATION AGREEMENT ("Agreement") is made and
entered into this 9th day of February, 1999, by and between TE PRODUCTS
PIPELINE COMPANY, LIMITED PARTNERSHIP, a Delaware limited partnership
("TEPPCO"); and BASF Fina Petrochemicals Limited Partnership ("LP"), a Texas
limited partnership; BASF Corporation, a Delaware corporation ("BASF"); and
Fina Oil and Chemical Company, a Delaware corporation ("Fina"); (Fina, BASF and
LP are individually and collectively sometimes referred to as "Contracting
Shippers");


                                  WITNESSETH:


         WHEREAS, Fina and BASF are constructing a petrochemical Plant adjacent
to Fina's refinery property located in or near Port Arthur, Texas;

         WHEREAS, at such time as the Plant becomes operational Fina and BASF
will have transportation requirements for the shipments of Ethylene and
Propylene and LP will have transportation requirements for shipments of Natural
Gasoline, between the Plant and Mont Belvieu, Texas;

         WHEREAS, TEPPCO, at Contracting Shippers request, is willing to
undertake the design, engineering, construction, operation and maintenance of
three (3) 12.75 inch outside diameter pipelines from Mont Belvieu, Texas to the
Plant for the purpose of transporting Ethylene, Propylene and Natural Gasoline
for Contracting Shippers subject to Contracting Shippers committing to ship
through such Pipeline Facilities a guaranteed volume of Products upon terms and


<PAGE>   6



conditions set forth in this Agreement and the Tariff covering such
transportation movements;

         WHEREAS, the three pipelines will be operated by TEPPCO as common
carrier facilities and as a result will offer to provide transportation
services to Third Party shippers in addition to Contracting Shippers under
terms and conditions set forth in the Tariff.

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements contained herein, and of other good and valuable
consideration the receipt and sufficiency of which are hereby acknowledged, and
intending to be legally bound hereby, TEPPCO, Fina, BASF and LP hereby agree as
follows:

                                   SECTION 1
                         DEFINED TERMS; INTERPRETATION

         1.1 Defined Terms. The terms defined in Appendix A, attached hereto
and incorporated herein shall, when used in this Agreement, have their
respective meanings specified in Appendix A, with each such definition of a
term being equally applicable to the singular and the plural forms of the term
so defined.

         1.2 References. All references in this Agreement to a "Section,"
"subsection" or "Exhibit" shall be to a Section, subsection or Exhibit of this
Agreement, unless the context requires otherwise. Unless the context otherwise
requires, the words "this Agreement," "hereof," "hereunder," "herein,"
"hereby," or words of similar import shall refer to this Agreement as a whole

                                       2

<PAGE>   7



and not to a particular Section, subsection, Exhibit, clause or other
subdivision hereof. Whenever the context requires, the words used herein shall
include the masculine, feminine and neuter gender, and the singular and the
plural.

         1.3 Interpretation. It is expressly agreed that this Agreement shall
not be construed against any Party, and no consideration shall be given or
presumption made, on the basis of who drafted this Agreement or any particular
provision hereof or who supplied the form of this Agreement. Each Party agrees
that this Agreement has been purposefully drawn and correctly reflects its
understanding of the transaction that this Agreement contemplates. In

                  by implication, the matter it illustrates;

             (b)  The word "includes" and its derivatives means "includes,
                  but is not limited to" and corresponding derivative
                  expressions;

             (c)  A defined term has its defined meaning throughout this
                  Agreement, regardless of whether it appears before or after
                  the place where it is defined; and

             (d)  The headings and titles herein are for convenience only and
                  shall have no significance in the interpretation hereof.

                                   SECTION 2
                              PIPELINE FACILITIES

         2.1      Design, Engineering and Construction. TEPPCO shall, at its 
sole cost and expense, provide or cause to be provided, the Pipeline
Facilities. Moreover, TEPPCO shall, at its sole cost and expense, design,
engineer, construct and install or cause to be designed, engineered,
constructed and installed, in a safe and environmentally sound manner, the
Pipeline Facilities capable of receiving and transporting the Products. The
design, engineering, construction and installation of the Pipeline Facilities
shall be performed in accordance with the provisions of Exhibit 2.1.

         2.2      Receipt and Delivery Facilities.

                  (a) TEPPCO shall incur non-reimbursable expenses at Mont
Belvieu of up to one million dollars for Mont Belvieu Work approved by
Contracting Shippers to tie Receipt and Delivery Facilities into the Mont
Belvieu Terminal. Exhibit 2.2 sets forth a diagram of TEPPCO's Mont Belvieu
Terminal facilities into which the Receipt and Delivery Facilities will be
tied. Any expenditures incurred by TEPPCO in excess of one million dollars for
such Mont Belvieu Work will be for Contracting Shippers' account; provided,
prior written approval is given by Contracting Shippers' to incur such excess
expenditures. Any such reimbursable expenditures shall not include any mark-up
for TEPPCO's profit, and shall be only those costs incurred by TEPPCO that are
associated with the Mont Belvieu Work. Reimbursement of such excess costs by
Contracting Shippers to TEPPCO shall be, at Contracting Shippers' sole
election, either

                                       4

<PAGE>   9



through (i) a surcharge, as determined by TEPPCO, to the Transportation
Charges, or (ii) a direct cash payment from Contracting Shippers to TEPPCO. If
Contracting Shippers do not unanimously agree on the applicable method of
reimbursement then the methodology set forth in item (i) directly above shall
be deemed elected by all Contracting Shippers. Any surcharge determination by
TEPPCO shall be calculated by taking (a) the costs incurred by TEPPCO, as
described above, times (b) a factor of 0.14 with the product of (a) and (b)
being divided by the applicable, annualized Guaranteed Monthly Volume. The
applicable calculation of the surcharge for Natural Gasoline will be as set
forth in the previous sentence and the applicable calculation of the surcharge
for Ethylene and Propylene will be the value from the previous sentence
multiplied by 100. Requests by Contracting Shippers for Mont Belvieu Work shall
be made in accordance with Section 5.4 of Exhibit 2.1.

         (b) Contracting Shippers shall each have the right, at their expense,
to examine the books and records of TEPPCO, during normal business hours, to
the extent necessary to verify the accuracy of any reimbursable expenses for
Mont Belvieu Work as described in Section 2.2(a). TEPPCO agrees to keep its
records and books of account in accordance with generally-accepted accounting
principals consistently applied. Contracting Shippers agree with TEPPCO that
Contracting Shippers' sole and exclusive remedy for any error or mistake made
by TEPPCO in computing such reimbursable expense shall be the recomputing of
such reimbursable expenses.

                                       5

<PAGE>   10



         2.3 Common Carrier Facilities. The Pipeline Facilities will be common
carrier facilities. TEPPCO's obligations and duties as a common carrier to
handle and transport volumes of Products received from Contracting Shippers as
well as its obligations and duties to all shippers which tender Products, shall
be determined pursuant to the Tariff filed by TEPPCO with the Commission;
provided, however, this understanding shall not be deemed to lessen or impair
any of the Parties' obligations hereunder.

         2.4 Authorizations and Rights-of-Way. TEPPCO shall apply for and use
Best Efforts to secure from proper persons and authorities all rights-of-way
(whether from private parties or any governmental agency or authority),
licenses, permits, property rights of ingress and egress, certificates,
servitudes, judgments, orders, rulings and other such authorizations
(collectively "Authorizations") as may be required for the purpose of
providing, locating, constructing, operating and maintaining the Pipeline
Facilities. Contracting Shippers each agree to cooperate with TEPPCO with
respect to any reasonable requests for assistance in seeking such
Authorizations and the granting and giving to TEPPCO any easements, licenses
and rights for TEPPCO to construct, maintain and operate any portion of the
Pipeline Facilities on property owned by or under the control of (i) Fina, (ii)
LP, and (iii) any Affiliates of either, for a total consideration of one
hundred dollars ($100.00). In that regard, the basic terms of any easement
granted by Fina, LP or their Affiliates pursuant to this Agreement shall
include that grantor shall not have the right to relocate the pipeline and

                                       6

<PAGE>   11



appurtenances except upon consent of grantee, that grantor shall provide
grantee a direct and reasonably convenient access to the easement area and
grantor represents that the easement is capable of being used for its intended
purpose. The foregoing terms shall be in addition to such other reasonable and
customary easement provisions.

         2.5 Changes in Design, Engineering and Construction. The design,
engineering and construction of the Pipeline Facilities shall comply with all
Laws and the provisions of Exhibit 2.1. Contracting Shippers shall have the
right to request changes in the design, engineering and construction of the
Pipeline Facilities, provided such changes are given in accordance with the
provisions of Exhibit 2.1. Any increases or decreases in the total costs and
expenses to design, engineer and construct the Pipeline Facilities due to such
changes requested by Contracting Shippers shall, in accordance with Exhibit
2.1, be properly reflected in increases or decreases to the Initial
Transportation Charges, unless Contracting Shippers elect to make a lump sum
settlement with TEPPCO.

         2.6 Commencement Date. The Commencement Date of this Agreement shall
be the later of (a) November 1, 2000, or (b) the first day of the Month
following the date TEPPCO notifies Contracting Shippers in writing that all
necessary testing of the Pipeline Facilities has been completed in accordance
with Exhibit 2.1, and the Pipeline Facilities are ready to commence service
with respect to the transportation of Products hereunder on a continuous basis.
As a matter of accommodation to Contracting Shippers and

                                       7

<PAGE>   12



subject to the terms and conditions of this Agreement, TEPPCO will notify
Contracting Shippers of the estimated date that TEPPCO will be ready to
commence service approximately six (6) Months prior thereto. Thereafter, TEPPCO
will advise Contracting Shippers each Month of any changes as to such estimated
date. After the Initial Contract Year commences, the Parties agree to enter
into a written memorandum supplemental to this Agreement specifying the
Commencement Date.

                                   SECTION 3
                      OPERATION OF THE PIPELINE FACILITIES

         3.1 Operation and Maintenance. Subject to the terms and conditions of
this Agreement, beginning as of the Commencement Date and continuing throughout
the Initial Term and any subsequent Contract Years following the Initial Term,
TEPPCO, through its General Partner, shall, at its sole cost and expense,
operate and maintain the Pipeline Facilities in accordance with industry-
accepted practices and procedures in the operation of common carrier facilities
and in accordance with all applicable Laws and the provisions of Exhibit 3.1.

         3.2 Utilities. TEPPCO shall furnish sufficient and adequately trained
personnel and material, including heat, light and power and other utilities and
services of any nature whatsoever used, consumed or needed to ensure TEPPCO's
safe and efficient receipt, transportation and delivery of Product as required
hereunder. Notwithstanding the immediately preceding sentence and

                                       8

<PAGE>   13



to the extent permitted under applicable Laws, Contracting Shippers shall
provide certain utilities and services as described in Attachment 2.2(b) to
Exhibit 2.1 attached hereto, to TEPPCO at the Pipeline System's Port Arthur
delivery and receipt facility at a nominal cost to TEPPCO. Unless agreed
otherwise by the Parties, Contracting Shippers shall be responsible for
providing sufficient pressure to move the Products from the Plant to the Mont
Belvieu Terminal in accordance with the process flow diagrams set out in
Attachment 2.3 to Exhibit 2.1 attached hereto.

         3.3      Product Specifications.

                  (a) Product tendered by Contracting Shippers for
transportation through the Pipeline Facilities shall meet the Product
specifications set forth in Attachment 2.2(b) to Exhibit 2.1 attached hereto.
Contracting Shippers' Product transported through the Pipeline Facilities may
be intermixed with product of Third Party shippers in the Pipeline Facilities,
which product of Third Party shippers shall also meet the specifications set
forth in Attachment 2.2(b) to Exhibit 2.1 attached hereto. Contracting
Shippers' Product shall be subject to changes in quality and other
characteristics as may result from such intermixing. Contracting Shippers and
any other shipper shall not be entitled to receive the identical Product
tendered by it to TEPPCO under the Tariff, although TEPPCO at its sole
discretion may be able, from time to time, to handle Contracting Shippers'
Products on a segregated basis. Delivery of Products by TEPPCO to Fina, BASF
and/or LP and other Third Party shippers shall be out of common stock in
TEPPCO's

                                       9

<PAGE>   14



common carrier pipeline system and shall meet the Product specifications as set
forth in Attachment 2.2(b) to Exhibit 2.1. Contracting Shippers shall not be
responsible or liable for any Products delivered to TEPPCO by any Third Party
that fail to meet the specifications set out in Attachment 2.2(b) to Exhibit
2.1.

                  (b) TEPPCO will accept Product for transportation hereunder
that does not meet the specifications in Attachment 2.2(b) to Exhibit 2.1
provided that:

                       (i)  Fina, BASF or LP, as the case may be, gives TEPPCO
                            acceptable timely notice of its desire to have
                            off-specification Product transported by TEPPCO
                            hereunder and full particulars of the specification
                            failures;

                      (ii)  Such off-specification Product will not harm, in
                            TEPPCO's good faith judgment, the Pipeline

<PAGE>   20

                               1 + ((A-B)x0.08)=C
                                     ---
                                      B
where:

         A =      The Consumer Price Index for the calendar month immediately
                  preceding the calendar month in which the Contract Year in
                  question begins.

         B =      The Consumer Price Index for the Month of October, 2000.

         C =      The annual adjustment factor to be applied to the Initial
                  Transportation Charges.

If during the term of this Agreement the publication of the Consumer Price
Index is discontinued or the methodology or data used to calculate such index
or indices is materially altered, a mutually agreeable index or indices, shall
be selected. If the Parties are unable to select such a substitute index or
indices, such shall be determined pursuant to Section 13.

         4.3 Improvements Required by Law. In the event that at any time, and
from time to time, after the Effective Date TEPPCO is required by any Laws not
in effect on the Effective Date, to make improvements to all or a portion of
the Pipeline Facilities or to otherwise incur therefor additional expenses for
public safety, pollution control or any other similar or dissimilar reason,
TEPPCO shall notify Contracting Shippers, as soon as reasonably possible, of
the full particulars of the requirements of such Laws and TEPPCO's good faith
estimate of the cost for compliance with such Laws. Notwithstanding anything
herein to the contrary, TEPPCO, subject to the provisions of this Section 4.3,
may increase the Transportation Charges hereunder to recover all or any portion
of such costs and expenses, of which TEPPCO has previously notified

                                       16

<PAGE>   21



Contracting Shippers, over the useful life of the Pipeline Facilities; provided
that TEPPCO makes a similar adjustment to any Third Party shipper's
transportation charges under the Tariff. TEPPCO shall notify Contracting
Shippers not less than ninety (90) days prior to the implementation of any
increase in the Transportation Charges under this Section 4.3, of the amount of
such increase, and the method of calculating such increase. Contracting
Shippers shall each have the right to dispute any such increase by notifying
TEPPCO, within thirty (30) days after receipt of TEPPCO's notice, of
Contracting Shippers' decision to dispute the amount of such increase and the
Parties shall meet and make a good faith effort to resolve the issue of the
appropriate amount of such increase, prior to TEPPCO implementing such
increase. If Contracting Shippers fail to timely notify TEPPCO of their
individual or collective decision respecting a notified increase, then it shall
be deemed for purposes of this Agreement that Contracting Shippers accept and
approve such increase.

         4.4 Implementation of Changes to Transportation Charges. The timing of
the implementation of any adjustments allowed pursuant to Sections 4.2 and 4.3
shall be at the discretion of TEPPCO, but in no event shall such adjustments be

for all or any portion of any increase allowed under Section 4.2 or TEPPCO may
elect not to implement any such increases at all. All decreases under Section
4.2 shall be implemented as soon as reasonably practicable under existing Laws.

         4.5 Tariff. Prior to the Commencement Date, TEPPCO shall file a Tariff
with the Commission and diligently pursue with Contracting Shippers' assistance
its timely commencement, covering the transportation of the Products and
reflecting pertinent charges, rates, terms and conditions of this Agreement.
Each of the Contracting Shippers shall have the right to review the Tariff,
including supplements and successive issues, prior to TEPPCO filing such with
the Commission.

         4.6 Changes to the Transportation Charges and Deficiency Rates
following the end of the Initial Term.

             (a)  At the end of the Initial Term of this Agreement, TEPPCO shall
                  reduce the then-existing Transportation Charges and Deficiency
                  Rates for each Product to an amount determined based on the
                  following formula:

                  Where:

                           A =      the Initial Transportation Charges for a
                                    Product.

                           B =      the Transportation Charges in effect for a
                                    Product immediately prior to the end of the
                                    Initial Term.

                           C =      the revised Transportation Charge and
                                    revised Deficiency Rate for a Product
                                    effective following the last day of the
                                    Initial Term.

             (b)  In the event that during the Initial Term the Transportation
                  Charges are increased pursuant to Section 4.3 then the Parties
                  shall mutually agree

                                       18

<PAGE>   23



                  on an additional amount to be reflected in the revised
                  Transportation Charges determined pursuant to Section 4.6(a)
                  for such previous adjustment.

             (c)  Such revised Transportation Charges shall be subject to
                  increases and decreases in accordance with Sections 4.2 and
                  4.3 for so long as the Agreement remains in effect after the
                  Initial Term.

<PAGE>   25



             applies) shall be subtracted from the Makewhole Volume Obligation
for such Delivery Month prior to calculating the Deficiency Charge for that
Delivery Month.

             (e) If Contracting Shippers do not have a Makewhole Volume
Obligation for a Delivery Month or there is more Excess Product Volumes than
Contracting Shippers' Makewhole Volume Obligation for such Month, then any
unused Excess Product Volume for such Product shall be credited to Contracting
Shippers and shall be subtracted from any Makewhole Volume Obligation that may
occur in any future Month.

             (f) Any Deficiency Charges paid by Contracting Shippers shall not

                                   SECTION 6
                              BILLING AND PAYMENT

         6.1 Invoice. Unless the Parties agree otherwise, TEPPCO shall submit
invoices to Fina, BASF and LP separately on or about the tenth (10th) day of a
Month. Each such invoice shall list for the preceding Month by Product the
quantity of Product transported during such Month by such Party, the
Transportation Charges and any

                                       21

<PAGE>   26



Excess Product Volume credits for such Month and any Deficiency Charges for
such Month. Any Deficiency Charges that cannot be directly attributed to Fina,
BASF or LP for such Month shall be shared equally among Fina, BASF and LP;
provided Fina, BASF and LP do not direct TEPPCO to allocate such Deficiency
Charges otherwise.

         6.2 Payments. Fina, BASF and LP shall pay to TEPPCO their respective
invoices within thirty (30) days of the date of such invoices by wire transfer
pursuant to instructions furnished by TEPPCO to Fina, BASF and LP.

         6.3 Late Payments. Any amounts not paid when due under Section 6.2
shall bear interest from the date due until paid, as applicable, at a rate
equal to four percent (4%) over the prime interest rate first published each
Month in The Wall Street Journal or if such rate is unlawful, the highest
lawful rate permitted. All obligations to make payments under this Agreement
are absolute and shall not be subject to any right of set-off or counterclaim
by reason of any Claim against the non-owing Party under this Agreement or
otherwise and the Parties hereby waive any such right of set-off or
counterclaim. Furthermore, a dispute as to whether a particular amount is due
shall not excuse non-payment. However, payment of any amount in dispute shall
not constitute a waiver of the paying Party's rights or an admission to the
paying Party's detriment with respect to such disputed amount. Notwithstanding
any provisions to the contrary in this Agreement, in no event shall this
Agreement require the payment or permit the collection or charging of interest
in excess of the maximum amounts legally

                                       22

<PAGE>   27



permitted by the applicable usury law. If any such excess of interest is
contracted for, charged or received under or in connection with this Agreement
so that under any circumstances whatsoever the amount of interest contracted
for, charged or received under or in connection with this Agreement exceeds the
maximum amount of interest permitted by such applicable usury law, then (a) the
interest limitations herein shall govern and control; (b) no person or entity
now or hereafter liable for such indebtedness shall be obligated to pay the
amount of such interest to the extent that it is in excess of the maximum
amount of interest permitted by such applicable usury law; (c) such excess
which may have been collected shall, at TEPPCO's election, be either (i)
applied as a credit against any amounts owed under this Agreement or other
agreements, or (ii) refunded to Fina, BASF or LP; and (d) the effective rate of
interest shall be automatically reduced to the maximum lawful contract rate
allowed for this Agreement under such applicable usury law.

         6.4 Remedies. In addition to the provisions of Section 11 of this
Agreement, if Fina, BASF or LP owes any amounts which are past due in excess of
thirty (30) days, TEPPCO may, in addition to any remedy available under any
applicable Law, require Fina, BASF or LP, as the case may be, to pay or furnish
guaranty of payment to TEPPCO prior to further acceptance of Product for
shipment or delivery hereunder.

                                   SECTION 7
                      MEASUREMENT AND INVENTORY ACCOUNTING

         7.1 Measurement. Unless otherwise mutually agreed in writing, the
method for measurement and testing of Product shall be as set forth in Exhibit
3.1 and the Parties agree that such shall be the exclusive method of measuring
and testing Product delivered by Contracting Shippers to TEPPCO at the Origin
Points and by TEPPCO to Contracting Shippers at the Delivery Points.

         7.2 Testing of Measuring Equipment. Fina, BASF, LP and TEPPCO shall
each have the right to have representatives present at all times of any
installing, reading, cleaning, changing, repairing, inspecting, calibration, or
adjusting done in connection with the other's measuring equipment or for
sampling or testing of Product. Fina, BASF, LP and TEPPCO shall each give the
others reasonable notice prior to the time of all tests so that the others may
conveniently have their representatives present.

         7.3 Records. Measurement, sampling, testing and other records
associated with the delivery and transportation of Product hereunder shall
remain the property of their owner, but upon request shall be made available to
the non-owner for inspection, verification and audit at all reasonable times;
provided, however that no Party shall be required to retain any record for a
period longer than thirty-six (36) Months from the creation of the record.

         7.4 Common Carrier Reports. TEPPCO shall furnish each of the
Contracting Shippers with reports of their respective receipts, deliveries,
inventory and sample analyses as are normally required

                                       24

<PAGE>   29



in common carrier pipeline operations and such other reports respecting
operations as may be mutually agreed by the Parties.

                                   SECTION 8
                          FORCE MAJEURE AND ALLOCATION

         8.1 TEPPCO Force Majeure. If by any reason of an event of Force
Majeure TEPPCO is rendered unable, wholly or in part, to perform its
obligations under this Agreement on or after the Commencement Date and if
TEPPCO gives notice as soon as practical of such event in accordance with
Section 14.2 and provides full particulars of such event in writing or by
facsimile transmission after the occurrence of an event of Force Majeure,
nonperformance of TEPPCO shall be excused during the continuance of such event
and to the extent its performance is affected by such event, subject to the
provisions of Sections 8.2. TEPPCO shall use due diligence to remedy its
nonperformance with all reasonable dispatch, including the making of provision
for such alternate performance as may be economical and practical.

         8.2 Abatement of Guaranteed Monthly Volume.

             (a) In the event TEPPCO is prevented from performing its
obligations hereunder due to a Force Majeure Event on or after the Commencement
Date, the collective Guaranteed Monthly Volume obligation of Contracting
Shippers under Section 5.2 hereof shall abate in the same proportion as the
inability of TEPPCO to perform during the period of such Force Majeure;
provided, however, the Initial Term shall be extended for the same period of
time that the

                                       25

<PAGE>   30



period of Force Majeure persists less the number of days equal to the result of
dividing the number of Barrels or Pounds of Product, as the case may be,
actually delivered by TEPPCO during said period, if any, by the applicable
Daily Minimum Volume (fractions to be rounded upward to the next whole number)
(the "Extension Term"). The Parties expressly agree that the Guaranteed Monthly
Volume obligation for each Product during the Extension Term shall be the sum
of the applicable Daily Minimum Volume for such Product for each day during the
Extension Term, if any. In the event Contracting Shippers should transport
collectively during any Month in which Force Majeure is claimed, the required
Guaranteed Monthly Volume of Product (subject to such Force Majeure) through
the Pipeline Facilities to the Delivery Point, then, in such event, there shall
be no Extension Term of this Agreement attributable to such Force Majeure
Event.

                  (b) By way of example, if TEPPCO on or after the Commencement
Date has a Force Majeure Event on the Natural Gasoline pipeline and Contracting
Shippers can only receive 20,000 barrels per day as a result of this event,
Contracting Shippers would receive a collective reduction in the Guaranteed
Monthly Volume for the applicable Month. In this example, it is assumed
TEPPCO's restriction on deliveries to Contracting Shippers lasts for six days.
The reduction to Contracting Shippers' collective Guaranteed Monthly Volume
would be 120,000 Barrels, which is computed by taking the Daily Minimum Volume
minus the actual daily deliveries during the period of Force Majeure multiplied
by the duration of

                                       26

<PAGE>   31



the Force Majeure Event (i.e., [40,000-20,000] multiplied by 6). In conjunction
with the above, the Initial Term of the Agreement for Natural Gasoline would be
extended by three days, which is calculated by taking the volume credit
received by Contracting Shippers' divided by the Daily Minimum Volume (i.e.,
120,000/40,000). In the above example, if Contracting Shippers' actual
deliveries during the Month of the Force Majeure Event were greater than the
Guaranteed Monthly Volume, there would be no extension of the Initial Term.

         8.3 Fina, BASF and LP Force Majeure. If by any reason of an event of
Force Majeure, Fina, BASF or LP is rendered unable, wholly on in part on or
after the Commencement Date, to perform its obligations under this Agreement
and if Fina, BASF or LP gives notice as soon as practical of such event in
accordance with Section 14.2 and provides full particulars of such event in
writing or by facsimile transmission after the occurrence of an event of Force
Majeure, nonperformance of Fina, BASF or LP, as the case may be, shall be
excused during the continuance of such event, except that Fina, BASF and LP
shall not be excused due to a Force Majeure Event or for reasons of Force
Majeure, of its obligations under Section 5 to make Deficiency Payments and
Fina, BASF and LP shall during such Force Majeure make timely payments of any
Deficiency Payments for their failure to ship or cause to be shipped the
applicable Guaranteed Monthly Volume of Products for reasons of Force Majeure
or otherwise. Fina, BASF and LP shall use due diligence to remedy their
respective nonperformance with all

                                       27

<PAGE>   32



reasonable dispatch, including the making of provision for such alternate
performance as may be economical and practical.

         8.4 Allocation. When shippers, including Fina, BASF and LP, tender
quantities of commodities to TEPPCO for shipment greater than can be
transported over the Pipeline Facilities for reasons other than a Force Majeure
Event, TEPPCO shall restrict or suspend receipts of commodities from all its
shippers (including receipts from Fina, BASF and LP of Product for
transportation hereunder) to the extent necessary, but only to the extent
necessary, to allocate its available transportation capacity among all its
shippers on an equitable pro rata basis based on historical levels of
shipments. In such event TEPPCO shall promptly notify Fina, BASF and LP by
telephone (to be confirmed in writing) of Fina's, BASF's and LP's allocated
capacity during such allocation period. If Fina's, BASF's and LP's allocated
capacity is less than their collective Daily Minimum Volume, then the
Guaranteed Monthly Volume obligation for the Product being allocated for the
Month during which such capacity allocation occurs shall be reduced by an
amount equal to the product of (i) the number of days during the Month the
Pipeline Facilities are on allocation, and (ii) the difference between the
applicable Daily Minimum Volume and Fina's, BASF's and LP's collective
allocated capacity for such Product.

         8.5 Disposal of Product. In the event Fina, BASF or LP is unable to
have Product delivered to it hereunder at the Delivery Point, as a result of
Force Majeure or any other cause, TEPPCO agrees to reasonably cooperate with
Fina, BASF and Partnership with

                                       28

<PAGE>   33



respect to Fina's, BASF's or LP's disposal of such Product in the Pipeline
Facilities; provided, however, if Fina, BASF or LP fail to make provisions for
such disposal, TEPPCO shall have the right but not the obligation, at Fina's,
BASF's and LP's sole cost and expense and for Fina's, BASF's and LP's account,
as the case may be, to dispose of any such Product at the best commercial price
then available under existing circumstances in order to free capacity in the
Pipeline Facilities.

                                   SECTION 9
                                      TERM

         9.1 Term. This Agreement shall be in full force and effect as of the
Effective Date and shall continue in effect for an Initial Term of twenty (20)
Contract Years, subject to any extension pursuant to Section 8.2, and shall
continue thereafter from Contract Year to Contract Year unless and until
terminated by TEPPCO, or any of the Contracting Shippers upon not less than 180
days prior written notice to the other Parties specifying a termination date
either at the end of (i) such Initial Term, or (ii) any subsequent Contract
Year.

         9.2 Termination. Notwithstanding Section 9.1, in the event Fina, BASF
or LP should ever purchase the Pipeline Facilities from TEPPCO, this Agreement
shall terminate upon such acquisition.

                                   SECTION 10
                                      LAWS

         This Agreement shall be subject to all Laws affecting either TEPPCO or
Contracting Shippers and should any of the Parties, by force of any such Laws
imposed at any time during the term of this Agreement, be rendered unable,
wholly or in part, to carry out its obligations under this Agreement, then this
Agreement shall nevertheless continue but shall be deemed modified to conform
with the requirements of such Laws. Notwithstanding the foregoing provisions of
this Section 10, this Agreement shall not be deemed to be so modified if such
Laws substantially and materially impairs any Party's rights and benefits as
herein provided, including but not limited to, services rendered hereunder or
TEPPCO receiving Transportation Charges and Deficiency Charges substantially in
accordance with the terms set forth herein, and, in such event, the Parties
shall negotiate in good faith to amend the terms of this Agreement so that such
Laws may be complied with and the Parties shall continue to receive the rights
and benefits herein provided. This Agreement is expressly made subject to the
Tariff and any inconsistencies between this Agreement and the Tariff shall be
resolved in favor of the Tariff; provided, however, TEPPCO shall not, without
Contracting Shippers prior written consent, seek to alter the character or
amount of TEPPCO's services or obligations herein provided or to reduce the
term of this Agreement. The Parties agree to assist each other (at the expense
of the requesting Party) in any proceeding before any Governmental

                                       30

<PAGE>   35



Authority having jurisdiction over this Agreement or the Tariff, to ensure that
the provisions of this Agreement and the Tariff continue in effect.

                                   SECTION 11
                                    DEFAULT

         In addition to any other provisions of this Agreement relative to
default, it is understood and agreed that if either Party hereto shall fail to
materially perform any of the covenants or obligations imposed upon it under
and by virtue of this Agreement and such covenants or obligations are of a
material nature, then in such event the other Party hereto may, at its option,
terminate this Agreement by proceeding as follows: The Party not in default
shall cause a written notice to be served on the Party in default stating
specifically the cause for terminating this Agreement declaring it to be the
intention of the Party giving notice to terminate the same; whereupon the Party
in default shall have thirty (30) days after the service of the aforesaid
termination notice in which to remedy or remove the cause or causes stated in
the notice for terminating the Agreement (the "Cure Period") and, if within
said Cure Period the Party in default does so remedy or remove said cause or
causes, then such termination notice shall be deemed withdrawn and this
Agreement shall continue in full force and effect. If the Party in default does
not so remedy or remove the cause or causes within said Cure Period, then, at
the option of the Party giving the termination notice, this Agreement shall

                                       31

<PAGE>   36



become null and void from and after the expiration of said Cure Period. If a
default cannot be substantially cured within the Cure Period, but the Party in
default has commenced to remedy the cause of default within the Cure Period and
continues diligently pursuing such remedy after expiration of the Cure Period,
then the Party not in default may not terminate this Agreement until such time
as the Party in default stops diligently pursuing a remedy of the default. Any
termination of this Agreement pursuant to the provisions of this Section 11
shall be without prejudice to the right of either Party to collect any amounts
then due and owing to it under the provisions of this Agreement and shall be
without prejudice to the rights of such Party to receive any Product for which
it has paid the Transportation Charges hereunder but has not received the
Product prior to the time of termination, and without waiver of or prejudice to
any remedy (legal, equitable or otherwise) to which the Party not in default
may be entitled for violations, default or breach of this Agreement. For
purposes of this Section 11, the term "Party" shall mean TEPPCO on the one hand
and Contracting Shippers, collectively on the other hand.

                                   SECTION 12
                                     TAXES

         12.1 TEPPCO Taxes. TEPPCO shall pay any and all applicable taxes
(including but not limited to ad valorem taxes, excise taxes, sales taxes and
value added taxes), fees, assessments and charges with respect to the Pipeline
Facilities used by TEPPCO to provide

                                       32

<PAGE>   37



transportation services under this Agreement. Contracting Shippers shall
cooperate with TEPPCO in any protest or contest by TEPPCO of such taxes solely
at TEPPCO's expense.

         12.2 Contracting Shippers' Taxes. Contracting Shippers shall each pay
any and all applicable taxes (including but not limited to ad valorem taxes,
excise taxes, sales taxes and value added taxes), fees, assessments and charges
with respect to the delivery, ownership, receipt, handling, use, and storage of
their respective Products in transit or the transfer of ownership of the
Products hereunder. TEPPCO shall cooperate with Fina, BASF and LP in any
protest or contest by any of them of such taxes solely at the requesting
Party's expense.

                                   SECTION 13
                                    DISPUTES

         13.1 Dispute Negotiations. In the event of any controversy or dispute,
whether based in contract, tort or otherwise, arising out of or relating to
this Agreement or the scope, breach, termination or validity of this Agreement,
the Parties shall promptly seek to resolve any such dispute by negotiations
between senior executives of the Parties who have authority to settle such
dispute. When a Party believes there is a dispute under this Agreement, that
Party may give the other Party written notice of the dispute. Within thirty
(30) days after receipt of such notice, the receiving Party shall submit to the
other a written response. Both the notice and responses shall include (i) a
statement of such Party's position

                                       33

<PAGE>   38



and a summary of the evidence and arguments supporting its position, and (ii)
the name, title, facsimile number, and telephone number of the executive who
will represent that Party. In the event the dispute involves a Claim arising
out of the actions of any Person or entity not a signatory to this Agreement,
the receiving Party shall have such additional time as necessary, not to exceed
an additional thirty (30) days, to investigate the dispute before submitting a
written response. The executives shall meet at a mutually acceptable time and
place within fifteen (15) days after the date of the response and thereafter as
often as they reasonably deem necessary to exchange relevant information and to
attempt to resolve the dispute. If one of the executives is an attorney or
intends to be accompanied at a meeting by an attorney, the other executives
shall be given at least five (5) working days' notice of such intention and may
also be accompanied by an attorney. All negotiations and communications
pursuant to this Section 13 shall be treated and maintained by the Parties as
confidential information and shall be treated as compromise and settlement
negotiations for the purposes of the Federal and State Rules of Evidence. The
term "Party" as used in this Section 13 shall mean TEPPCO on the one hand and
Contracting Shippers collectively on the other hand.

         13.2 Arbitration. Any disputes arising under the provisions of (i)
Section 4.2 of this Agreement relative to selecting a substitute index in place
of any discontinued index, or (ii) Section 4.1 of Exhibit 2.1 of this Agreement
relative to

                                       34

<PAGE>   39



determining Related Costs (as that term is defined in Exhibit 2.1) caused by
the rerouting of the Pipeline Facilities (collectively "Dispute") that are not
settled pursuant to the foregoing provisions may be submitted to binding
arbitration in accordance with the following provisions. No other dispute shall
be subject to arbitration hereunder, unless otherwise expressly agreed to by
the Parties.

                  (a)      The Party desiring to initiate arbitration in
                           connection with any Dispute shall send, via
                           certified mail, written notice of demand of
                           arbitration to the other Party and the name of the
                           arbitrator appointed by the Party demanding
                           arbitration together with a statement of the matter
                           in controversy.

                  (b)      Within fifteen (15) days after receipt of such
                           demand, the receiving Party shall name its
                           arbitrator.  If the receiving Party fails or
                           refuses to name its arbitrator within such 15-day
                           period, the second arbitrator shall be appointed,
                           upon request of the Party demanding arbitration, by
                           the Chief U.S. District Court Judge for the
                           Southern District of Texas ("Judge") or such other
                           person designated by the Judge.  The two
                           arbitrators so selected shall within fifteen (15)
                           days after their designation select a third
                           arbitrator; provided, however, that if the two

                                       35

<PAGE>   40



                           arbitrators are not able to agree on a third
                           arbitrator within such 15-day period, either Party
                           may request the Judge or such other person
                           designated by the Judge to select the third
                           arbitrator as soon as possible. In the event the
                           Judge declines to appoint an arbitrator, appointment
                           shall be made, upon application of either Party,
                           pursuant to the Commercial Arbitration Rules of the
                           American Arbitration Association. If any arbitrator
                           refuses or fails to fulfill his or her duties
                           hereunder, such arbitrator shall be replaced by the
                           Party which selected such arbitrator (or if such
                           arbitrator was selected by another Person, through
                           the procedure which such arbitrator was selected)
                           pursuant to the foregoing provisions.

                  (c)      Each arbitrator selected by the Parties shall be
                           qualified by education, experience and training to
                           pass on the particular question in Dispute. The
                           arbitrators selected by the Parties are not required
                           to be neutral, but the third arbitrator shall be
                           neutral, and must be a practicing attorney, a judge
                           or a retired judge.

                  (d)      The Parties hereto hereby request and consent to the
                           three (3) arbitrators conducting a hearing in
                           Houston, Texas no later than sixty (60) days

                                       36

<PAGE>   41



                           following their selection or thirty (30) days after
                           all prehearing discovery has been completed,
                           whichever is later, at which the Parties shall
                           present such evidence and witnesses as they may
                           choose, with or without legal counsel.

                  (e)      Arbitration shall be conducted in accordance with
                           the Commercial Arbitration Rules and procedures of
                           the American Arbitration Association.

                  (f)      The Federal Rules of Civil Procedure, as modified
                           or supplemented by the local rules of civil
                           procedure for the U.S. District Court for the
                           Southern District of Texas, shall apply in the
                           arbitration.  The Parties shall make their
                           witnesses available in a timely manner for
                           discovery pursuant to such rules. If a Party fails
                           to comply with this discovery agreement within the
                           time established by the arbitrators, after
                           resolving any discovery disputes, the arbitrators
                           may take such failure to comply into consideration
                           in reaching their decision.  All discovery disputes
                           shall be resolved by the arbitrators pursuant to
                           the procedures set forth in the Federal Rules of
                           Civil Procedure.

                  (g)      Adherence to formal rules of evidence shall not be
                           required. The arbitrators shall consider any
                           evidence and testimony that they determine to be

                                       37

<PAGE>   42



                           relevant.

                  (h)      The Parties shall request that the arbitrators
                           render their decision within thirty (30) calendar

in the Contract Documents shall mean calendar day.

                  (e) In the interest of brevity, the Contract Documents
frequently omit modifying words such as "all" and "any" and articles such as
"the" and "an," but the fact that a modifier or an article is absent from one
statement and appears in another is not intended to affect the interpretations
of such statement.

SECTION 4      ACQUISITION OF RIGHT-OF-WAY

         4.1      Acquisition of Right-of-Way.

                  (a) Subject to the provisions of Section 2.4 of the Agreement,
TEPPCO shall take all steps necessary to obtain right-of-way ("Pipeline
Right-of-Way") along the anticipated route of the


                                        7

<PAGE>   66


Pipeline Systems described in Attachment 2.2(a) (the "Projected Pipeline
Right-of-Way") and use its Best Efforts to secure assignment rights for the
Pipeline Right-of-Way where available. If TEPPCO (i) after using its Best
Efforts is unable to obtain a Pipeline Right-of-Way over any segment of the
Projected Pipeline Right-of-Way, or (ii) determines in good faith that it is not
cost beneficial to the overall Project under the circumstances to obtain a
Pipeline Right-of-Way, then TEPPCO shall determine, in its good faith judgment,
the most appropriate rerouting or reroutings for the overall Project taking into
account Related Costs and changes, if any, in the Projected Final Completion
Date due to such rerouting or reroutings from the Projected Pipeline
Right-of-Way. TEPPCO shall promptly advise Contracting Shippers of any such
proposed rerouting or reroutings and the Related Costs required by such
rerouting. In addition, TEPPCO shall advise Contracting Shippers of any adverse
impact on the Projected Final Completion Date due to such rerouting as compared
to proceeding with the acquisition of that portion of the Projected Pipeline
Right-of-Way that is being rerouted around. Thereafter, TEPPCO and Contracting
Shippers shall promptly meet to discuss in good faith all aspects of the
proposed rerouting deviations. If, at such meeting, the Parties are unable to
agree upon a rerouting option, TEPPCO shall nonetheless promptly proceed with
the proposed rerouting option it deems is in the best overall interest of the
Project under the circumstances, provided that such rerouting option will not,
in TEPPCO's good faith judgment, have an adverse impact on the


                                        8

<PAGE>   67


Projected Final Completion Date as compared to proceeding with the acquisition
of that portion of the Projected Pipeline Right-of-Way that is being rerouted
around. If TEPPCO determines in its good faith judgment after consulting with
Contracting Shippers that such reroute will have an adverse impact on the
Projected Final Completion Date, TEPPCO will not proceed with the reroute
without the consent of Contracting Shippers, but will proceed with acquiring
that portion of the Projected Pipeline Right-of-Way that was proposed to be
rerouted around. Any dispute as to the Related Costs due to a rerouting of the
Pipeline Facilities shall be resolved in accordance with Section 13 of the
Agreement including binding arbitration if the Parties are unable to resolve the
dispute in accordance with Section 13.1 of the Agreement.

                  (b) All costs and expenses of any rerouting from the Projected
Pipeline Right-of-Way that is required due to difficulties or complications in
the design, engineering or construction of the Pipeline Facilities in the
Projected Pipeline Right-of-Way shall be the sole responsibility of TEPPCO.

         4.2      Sharing Costs and Expenses for Right-of-Way.

                  (a) Except as provided in Section 4.2(b) below, TEPPCO shall
be responsible for all actual costs and expenses, including attorneys fees,
associated with securing the appropriate Authorizations, and all Related Costs
(collectively "Costs").

                  (b) If the total of all such Costs exceed $19 million,
Contracting Shippers shall be responsible for or otherwise reimburse TEPPCO for
all Costs in excess of $19 million.

<PAGE>   68



             (c) TEPPCO shall provide, on a biweekly basis, a report 
summarizing Pipeline Right-of-Way acquisition activities to the right-of-way
management personnel designated by Contracting Shippers. This biweekly report
will contain (i) a list of landowners and parcels in each of the five
geographically distinct budget areas, (ii) current status of landowner contacts
and settlements, (iii) an accounting of the percentage of the Pipeline
Right-of-Way acquired in each budget area, (iv) an accounting of the amount
spent on each tract and the percentage of the budget spent in each budget area,
(v) and an accounting of the percentage of the total budget spent. If the total
of all Costs (inclusive of reasonably estimated future Costs) exceeds $16.5
million, the report will also contain a status report on each remaining
unsettled landowner and the planned next steps to resolve any differences
between TEPPCO and the landowner as to TEPPCO's acquiring the Pipeline
Right-of-Way across that landowner or the affected parcels of property.

SECTION 5      THE WORK AND CHANGES IN THE WORK

         5.1 The Work. The "Work" shall include, (i) all materials, systems,
equipment, and other installations becoming a part of the Project pursuant to
the Contract Documents (sometimes collectively referred to as "Materials"), (ii)
all other materials, supplies, apparatus, implements, tools, equipment, sanitary
facilities and other facilities not included in item (i) preceding and necessary
in the construction of the Project, (iii) all labor, supervision,


                                       10

<PAGE>   69


transportation, utilities, storage and other services (sometimes collectively
referred to as "Services") required in the construction of the Project, (iv) all
cutting and fitting required to complete the Work or make its parts fit together
properly, (v) all other acts and all other things necessary to construct the
Project in accordance with the Contract Documents, including all work expressly
specified therein and such other work as may reasonably be inferred therefrom,
and (vi) any other work or services described in this Exhibit or any other
Contract Documents as a part of the Work.

         5.2 Title and Risk of Loss

             Title to all Work shall be in TEPPCO and TEPPCO shall bear the 
risk of loss of all Materials.

         5.3 Standards for Materials. All Materials shall be new and of high
quality, meet industry standards, be fit for the intended use and purpose and
meet all requirements of the Drawings and Specifications and Laws.

         5.4 Changes in Work.

             (a) Contracting Shippers may request changes in the Work by giving
TEPPCO a written request (a "Proposal Request") setting forth in detail the
nature of the change in the Work requested (the "Change Work"). TEPPCO may upon
its own motion prepare a "Proposal Request" for approval. Upon receipt of a
Proposal Request from any of the Contracting Shippers or upon preparation of
TEPPCO's own Proposal Request, TEPPCO shall as soon as reasonably practical
submit to each of the Contracting Shippers a written proposal


                                       11

<PAGE>   70


("Change Order Proposal") on a form as shown in Exhibit 5.4 setting forth in
reasonable detail, (i) a description of the scope of work approved by TEPPCO
resulting from the proposed Change Work request, (ii) any change in the
Projected Final Completion Date required due to such requested change, and (iii)
a stipulated sum for the performance of the Change Work. The stipulated sum
contained in any Change Order Proposal shall be based on TEPPCO's estimated
actual costs including (i) all labor and other costs of Contractor and any
Subcontractors, and (ii) any Material costs plus any mark-ups agreed to by
TEPPCO, Contractor and Subcontractor, as the case may be. The stipulated sum
shall not include any amount for profit to TEPPCO. Each Change Order Proposal
shall be accompanied by appropriate data supporting such estimate, including but
not limited to bids, cost estimates and wage schedules. When the Change Work
involves both new Work not originally required under the Contract Documents and
replacement or obviation of previously planned Work, TEPPCO shall break down the
stipulated sum contained in its Change Order Proposal to show both the
additional compensation bid for the new Work and the credit allowed for the
replaced or obviated Work. If Contracting Shippers approve such Change Order
Proposal, TEPPCO will issue and Contracting Shippers will execute and accept a
written modification (a "Change Order") pursuant to which the Change Work
described in the Change Order Proposal will be performed. Such Change Order
shall set forth the agreed stipulated sum for such Change Work and any
adjustment required to be made in the Projected Final Completion Date, which


                                       12

<PAGE>   71


date shall be so adjusted as set forth in the Change Order. If Contracting
Shippers do not approve a Change Order Proposal, TEPPCO shall be paid for any
Third Party costs required to prepare the proposal, unless TEPPCO initiated such
proposal, and TEPPCO will have no further obligation with regard to the
requested change. For purposes of this Section 5.4(a), Contracting Shippers must
approve a Change Order Proposal within four (4) days of its issuance to
Contracting Shippers by TEPPCO, otherwise such shall be deemed "not approved" by
Contracting Shippers.

                  (b) Not later than ninety (90) days prior to the Completion
Date TEPPCO shall advise each of the Contracting Shippers in writing of (i) the
aggregate amount of the stipulated sums for all the Change Orders ("Total
Stipulated Amount"), and (ii) a proposed adjustment to the Initial
Transportation Charges resulting from such Total Stipulated Amount, which
adjustment shall be calculated by taking such Total Stipulated Amount times a
factor of 0.14 with the product being divided by the applicable annualized
Guaranteed Monthly Volume. The applicable adjustment to the Initial
Transportation Charges for Natural Gasoline will be as set forth in the previous
sentence and the applicable calculation of the adjustment to the Initial
Transportation Charges for Ethylene and Propylene will be the value from the
previous sentence multiplied by 100. Each of the Contracting shippers, within
thirty (30) days after receiving such written notice shall advise TEPPCO of
their decision either (y) to pay in full the Total Stipulated Amount, which
payment shall be then due and owing, or (z) to make


                                       13

<PAGE>   72



the adjustment in the Initial Transportation Charges as set forth in TEPPCO's
written notice. If Contracting Shippers do not collectively agree on the method
of reimbursing TEPPCO for the Total Stipulated Amount then the method described
in item (z) above shall be deemed selected by all the Contracting Shippers.

         (c) Changes in the Work due to deviations in the Projected Pipeline
Right-of-Way shall be handled in accordance with the provisions of Section
4.1(a) and (b) of this Exhibit 2.1 and not pursuant to Section 5.4 of this
Exhibit 2.1.

</TABLE>

The total sum of any such early completion bonus payment shall not exceed $1.5
million. Any such early completion bonus payment shall be paid within thirty
(30) days after the Completion Date.

                  (c) TEPPCO acknowledges that Contracting Shippers' businesses
will be damaged if the Completion Date does not occur by the Projected Final
Completion Date, and TEPPCO and Contracting Shippers agree that the exact
measurement of such damages is difficult, if not impossible, to determine, and
the amounts provided for in subsection 7.3(a) as liquidated damages are
reasonable estimates of the aggregate of all damages to Contracting Shippers'
collective businesses caused by such delay.

                  (d) Notwithstanding anything in this Agreement to the

         7.4 Delay.

             (a) If the progress of the Work on the critical path of the most 
recent updated version of the Project Schedule is delayed at any time by (i) an
act or the neglect of Contracting Shippers, (ii) by changes in the Work
pursuant to Section 5.4 of this Exhibit or Section 2.2 of the Agreement, (iii)
by Construction Force Majeure as defined in Exhibit A-2.1, (iv) any delay due
to the rerouting of the Pipeline System as determined in accordance with
Section 4.1 of this Exhibit 2.1, or (v) subject to Section 9 of this Exhibit,
delay due to a pending resolution of a dispute, in each case not reasonably
anticipated by TEPPCO and beyond TEPPCO's reasonable control, then the
Projected Final Completion Date shall be extended for the days of delay;
provided, however, that TEPPCO shall not be entitled to any extension to the
extent that any such event could have been prevented or overcome by TEPPCO or
its Contractor through the exercise of such diligence and reasonable care as
would be exercised by a prudent Person under similar circumstances. TEPPCO
shall as far as reasonably possible, remedy any delay due to Construction Force
Majeure with all reasonable dispatch. It is understood and agreed that the
definition of Force Majeure in Exhibit A to the Agreement shall not be used or
asserted with respect to a delay in the progress of the Work under this Section
7.4.

<PAGE>   83



             (b) In the event Contractor is delayed at any time in the progress
of the Work on the critical path of the most recent updated version of the
Project Schedule, which delay is subject to force majeure under Contractor's
contract, then the Projected Final Completion Date shall be extended for the
same period of time; provided that such force majeure would be a Construction
Force Majeure event as defined in Exhibit A-2.1. TEPPCO shall use reasonable
efforts to provide in its contract with Contractor that if any delay due to
Construction Force Majeure should continue for sixty (60) days, TEPPCO shall
have the right to terminate its contract with Contractor.

             (c) TEPPCO shall notify Contracting Shippers in writing of any
delay that would extend the Projected Final Completion Date as soon as
reasonably possible after the occurrence of the delay. TEPPCO shall provide in
the notice an estimate of the probable effect of such delay on the progress of
the Work.

             (d) The amount of any extension in the Projected Final Completion 
Date for whatever reason incurred, will be based only on actual delays
occurring on Monday through Sunday, excluding holidays.

         7.5 Contracting Shippers' Obligations. Contracting Shippers shall each
furnish TEPPCO with all information which Contracting Shippers are required to
furnish to TEPPCO within the time limits expressly required hereunder. Decisions
and approvals required of Contracting Shippers under the Contract Documents

                               SAMPLE CALCULATIONS


(a)      Liquidated Damages Calculation Example

         Assume that the Final Completion occurs at 3 PM on November 23, 2000.
Therefore, the Final Completion Date occurred 38 days after the Projected Final
Completion Date. The liquidated damages are calculated as follows:

<TABLE>
<S>      <C>                   <C>
         21 days x $0 =        $        0
          9 days x $50,000 =   $  450,000
          8 days x $75,000 =   $  600,000
        ---                    ----------
         38 days           =   $1,050,000   Liquidated Damages
</TABLE>




(b)      Bonus Calculation Example

         Assume that the Final Completion occurs at 3PM on September 5, 2000.
Therefore, the Final Completion Date occurred 41 days before the Projected Final
Completion Date. The bonus is calculated as follows:

<TABLE>
<S>      <C>                  <C>
         14 days x $0 =       $        0
          7 days x $25,000 =  $  175,000
         20 days x $50,000 =  $ 1,000,000
         41 days              $ 1,175,000    Bonus

be a prerequisite to TEPPCO's taking such steps and initiating such actions as
are necessary to deal with the Emergency and to provide immediate safeguards to
public safety and health and the environment if, in TEPPCO's sole opinion, such
notification or the accommodation of Requests would be impractical. TEPPCO will
ensure the development of coordinated emergency response plans with Contracting
Shippers and any other Third Party shipper.

measured through facilities equipped with turbine flow meters or other type of
flow meters of standard make and design which will ensure accurate measurements.
The output of the meters will be transmitted to computing and recording
instruments to ensure accurate documentation of the measurements. The meters
shall be operated between the minimum and maximum flow rates per the
manufacturer's specifications for each meter.

             (b) The Product pressure and temperature during the custody
transfer will be determined by continuous, on-line, industry accepted
transmitters. If transmitter should fail, manual temperatures or pressures will
be taken at the meters and input into the flow computer as a fixed value.

             The Natural Gasoline density will be based on on-line real time 
input into the flow computer. Should the on-line density instrument fail, the
density will be manually input into the flow computer as a fixed value. The
Propylene density will be based on 100% pure propylene with a density of .5228
as per API 11.3.3.2.

             (c) The volume corrections factors used for Natural Gasoline
to net the volumes to standard conditions will be based on the latest API Manual
of Petroleum Measurement Standards, Chapter 11.1, Volume Correction Factors,
Table 6A and Chapter 11.2.2 Compressibility Factors for Hydrocarbons: 0-90 API
Gravity Range.

<PAGE>   101



                  (d) The volume corrections factors used for Propylene to net
the volumes to standard conditions will be based on the latest API Manual of
Petroleum Measurement Standards, Chapter 11.3.3.2 Propylene Compressibility.

                  (e) Propylene mass flowrate in Pounds shall equal gross
flowrate times Meter Factor times Flowing Specific Gravity times weight of H20
at 60(degree)F and 14.696 psia.

                  Where:            (1)  Flowing Specific Gravity equals
                                         (Calculated Flowing Density in Lbs/Ft3
                                         times 0.0161846) divided by 0.999012.

                                    (2)  Calculated Flowing Density equals
                                         density at flowing temperature and
                                         pressure calculated using API
                                         Chapter 11.3.3.2.

                                    (3)  Meter Factor equals a dimensionless
                                         term obtained by dividing the gross
                                         standard volume of liquid passed
                                         through the meter (as measured by a
                                         prover during proving) by the
                                         corresponding meter indicated volume
                                         at standard conditions.

                  (f) TEPPCO will notify Contracting Shippers of any instrument
or computer problem that is discovered which impacts a specific Product
shipment.

               7.2    Proving and Calibration Procedures of Meters

                  (a) TEPPCO shall prove the custody transfer meters for Natural
Gasoline and Propylene a minimum of twice each Month in accordance with the API
Manual of Petroleum Measurement Standards, Chapter 4, Proving Systems. TEPPCO
will promptly notify Contracting Shippers if this proving requirement cannot be
met.

                  (b) A valid proving will consist of a minimum of five (5)
consecutive proof runs that repeat within 0.05% of each run.

                  (c) Pressure and temperature instrumentation and

                                       11

densitometers used as computer input will be calibrated each calendar quarter in
accordance with API and ASTM standards and manufacturer's specifications and
requirements. Records of the calibrations and tests will be maintained by TEPPCO
and will be open for inspection by Contracting Shippers at any reasonable time.

                  (d) Following any calibration of temperature or pressure
instrumentation, any equipment found to be inaccurate shall, prior to its use,
be calibrated or replaced with equipment that accurately functions.

                  (e) TEPPCO shall supply Contracting Shippers upon request with
documentation of the results of any meter proving or instrument calibration test
performed, whether witnessed or not witnessed by Contracting Shippers
representatives. TEPPCO will immediately notify Contracting Shippers of any
variance of meter factors, temperatures, pressures or gravities which will
affect booked volumes.

         7.3      Billing Adjustments

                  (a) TEPPCO will adjust previous meter volumes for Natural
Gasoline and Propylene if:

                      1.       any temperature instrument is found to be
                               inaccurate by more than one (1) degree 
                               Fahrenheit.

                      2.       any pressure instrument is found to be
                               inaccurate by more than ten (10) PSIG.

                      3.       any densitometer is found to be inaccurate
                               by more than two (2) API degrees.

                                       12

<PAGE>   103



                      4.       the meter's factor changes by more than
                               0.25% from the previous meter factor.

                  (b) The following guidelines will be used to determine the
volume of Product subject to adjustment:

                      1.       If the duration of the inaccuracy is known
                               or agreed upon, the volume booked shall be
                               corrected for the period of the inaccuracy.

                      2.       If the duration of the inaccuracy is not
                               known or agreed upon, one half (1/2) of the
                               volume booked since the last calibration of
                               the equipment in error shall be corrected.

                  (c) If, for any reason, any instrument is out of service or in
disrepair such that Product delivery cannot be accurately determined, the
quantity delivered during the period of outage or malfunction shall be estimated
using the first feasible method shown below and agreed to by the Parties:

                      1.       By using the volumes measured by Contracting
                               Shippers' metering station, provided
                               Contracting Shippers' measurement equipment

                      2.       By correcting the error if the percentage or
                               amount of the error is determined by
                               calibration, test, or mathematical
                               calculation. All calibrations must meet API
                               standards.

         8.3 Check Meters. Contracting Shippers shall have the right at their
cost and expense to install and maintain check meters in series with TEPPCO's
meters. Such orifice meters shall be installed and operated in accordance with
the specifications prescribed in API MPMS 14.3 (ANSI/API 2530) entitled "Orifice
Metering of Natural Gas" (formerly Gas Measurement Committee Report Number 3 of
the American Gas Association) and any subsequent modifications to API MPMS 14.3,
(ANSI/API 2530).

         8.4 Calibration. The measurement equipment is to be calibrated
quarterly by TEPPCO in the presence of representatives of the Contracting
Shippers, if Contracting Shippers choose to be represented, and the Parties
shall jointly observe any necessary adjustments that are made in the measuring
equipment. Each Party shall give to the other Party notice of the time of all
regular tests of measuring equipment and other tests called for herein
sufficiently in advance of the holding of such tests so that the other Parties
may conveniently have their representatives present. If any Party at any time
desires a special test of any measuring equipment, it will promptly notify the
other Parties, and the Parties will then cooperate to promptly secure a
calibration test and jointly observe any adjustments. If, upon any special test,
the measuring equipment is found to be no more than one percent (1%) erroneous
in the aggregate, the entire cost of such test shall be paid for by the Party
requesting the test and previous readings of such equipment shall be considered
correct in computing deliveries hereunder.


                                       15

<PAGE>   106


         8.5 Billing Adjustment. If, upon any test, any measuring equipment is
found to be inaccurate by more than one percent (1%), such equipment shall be
adjusted to read accurately, and the previous readings shall be corrected for
such inaccuracy for any period which is definitely known and agreed upon. In
case the period is not definitely known and agreed upon, then the readings shall
be corrected for a period extending back one-half (1/2) of the time elapsed
since the last date of calibration, not to exceed a period of thirty (30) days.
If, for any reason, measuring equipment is inoperative so that the amount of
Ethylene delivered cannot be ascertained, then the volume of Ethylene delivered
during the period such measuring equipment is inoperative shall be estimated and
agreed upon by the Parties upon the basis of the best data available by using
the first of the following methods which is feasible:

             (a) By using the registration of any check-measuring 
equipment, if installed and accurately registering;

             (b) By correcting the error, if the percentage of error is
ascertainable by calibration, test, or mathematical calculation; or

             (c) By estimating the quantity of delivery through analysis of
actual deliveries made during preceding periods under conditions when measuring
equipment was registering accurately.

         Claims of any Party concerning the quantity of Ethylene, Propylene or
Natural Gasoline delivered must be submitted in writing within 180 days from the
date of commencement of the claimed discrepancy.
