and  Conflicts  Committee  of  Enterprise GP  (collectively  the  "Committees"),
pursuant to the following provisions:

     With respect to the board of directors and any successor  governing body of
Enterprise GP  (the "GP Board"),  Tejas  Energy shall be entitled,  from time to
time during the term of this Agreement,  to designate  certain members of the GP
Board  (with Tejas  Energy's  initial  designation  to become  effective  on the
Closing Date), as follows:

     Tejas  Energy  shall be entitled to  designate  one-third of the GP Board's
members for so long as and provided Tejas Energy and/or its Affiliates  maintain
more than a 20% equity interest in Enterprise GP;

     Tejas Energy shall be entitled to  designate  two-ninths  of the GP Board's
members for so long as and provided Tejas Energy and/or its Affiliates  maintain
less than or equal to a 20% but more than a 10% equity  interest  in  Enterprise
GP; and

     Tejas  Energy  shall be entitled to  designate  one-ninth of the GP Board's
members (but in any event at least one Board member)  provided  Tejas Energy and
its  Affiliates  collectively  own at least 5 million of the Tejas Units  and/or
Article IV Units.

     In the event the calculation of Tejas Energy's percentage representation on

fractional  number shall be rounded to the nearest  whole number which shall not
be less than one.

     With  respect to all  Committees  (other than the  Executive  Committee  of

designated as a director,  committee  member or  representative  by Tejas Energy
dies,  resigns,  or becomes  disabled or  incapacitated,  Tejas  Energy shall be
entitled to designate a  replacement,  and each  director,  committee  member or
representative  designated  by Tejas Energy shall serve in such  capacity  until
removed or replaced by Tejas  Energy.  Upon the  termination  of Tejas  Energy's
designation  rights  set  forth in this  Article II,  the  directors,  committee
members and  representatives  appointed by Tejas Energy  pursuant to such rights
may be removed by the Committees on which they serve and Tejas Energy shall have
no  right  to  replace   such   removed   directors,   committee   members   and

         Section  Executive Committee.

     At the  Closing,  Enterprise  GP shall  establish a  five-member  executive
committee(the  "GP  Executive  Committee").  Tejas  Energy  will be  entitled to
designate  two  members to serve on the GP  Executive  Committee  as long as the
collective  equity  interest of Tejas Energy and its Affiliates in Enterprise GP
is equal to or greater  than 10%.  If the  collective  equity  interest of Tejas
Energy and its Affiliates in Enterprise GP is less than 10% but Tejas Energy and
its Affiliates collectively own at least 5 million of the Tejas Units and/or the
Article IV Units,  then Tejas Energy shall  thereafter  be entitled to designate
only one member of the GP Executive Committee. If the collective equity interest
of Tejas Energy and its  Affiliates  in Enterprise GP is less than 10% and Tejas
Energy  and its  Affiliates  collectively  own less than 5 million  of the Tejas
Units  and/or the Article IV Units,  then Tejas  Energy shall not be entitled to
designate any member of the GP Executive Committee.

     All matters relating to the items listed below must be submitted to and are
subject  to the  approval  of  the  GP  Executive  Committee.  The GP  Executive
Committee will decide matters by majority vote,  provided that,  until such time
as all of the Special Units (other than any Special Units not issued as a result
of a failure to meet the performance  tests  referenced in Section 5.3(d) of the
Partnership Agreement) have been converted to Common Units and such Common Units
have a Closing Price in excess of $24 per Common Unit  (appropriately  Adjusted)
for each trading day during a period of 120 consecutive  calendar days (with any
trading  days during  which Tejas  Energy is  prevented  from trading its Common
Units,  as a result of  (i) black-out  periods  under  Section  2(b)(ii)  of the
Registration  Rights  Agreement  referenced in the  Contribution  Agreement (the
"Registration  Rights  Agreement")  or (ii) in the event Tejas Energy desires to
sell  such  Common  Units in a  manner  not  requiring  registration  under  the
Securities Act and Tejas Energy advises Enterprise Partners of such intention in
writing, Tejas Energy having been advised by Enterprise Partners in writing that
there is material  non-public  information  relating to Enterprise Partners that
would  prevent such a sale,  not counting  toward such  120-day  total),  the GP
Executive  Committee  must  receive the vote of at least one of the Tejas Energy

equity ownership in Enterprise Partners,  Enterprise  Operating  (indirectly) or
Enterprise GP of other pre-merger or pre-consolidation  owners by reason of such
merger or  consolidation,  and provided  that  Enterprise  Partners,  Enterprise

     Section Designated Purchase Price. For purposes of this Agreement,  (i) the
term  "Designated  Purchase  Price" shall mean the Closing Price for the subject
securities  as of the Business  Day  immediately  preceding  the exercise of the
applicable  option under this  Agreement  or, with respect to a  calculation  of
Total Enterprise Value, the Business Day immediately  preceding such calculation
(in either case, the "Determination Date"), or if there is no applicable Closing
Price,  shall mean the Fair Market Value of the subject securities on such date,
and (ii) "Fair Market Value" shall mean the fair market value of the  securities
as determined by mutual agreement of the selling party and the purchasing party;
provided  that, if within five Business Days following the  Determination  Date,
the selling party and the purchasing  party cannot agree upon fair market value,
then the  selling  party and the  purchasing  party  shall agree upon a mutually
acceptable  financial expert who shall determine fair market value. In the event
that,  within ten Business Days  following the  Determination  Date, the selling
party and the purchasing party cannot agree upon a mutually acceptable financial
expert,  then each of the selling party and the  purchasing  party will select a
financial expert and the two financial  experts as selected shall select a third
financial  expert who shall  determine Fair Market Value.  If either the selling
party or the purchasing party fails to

notice of the other party's designation,  the financial expert designated by the
other party will determine Fair Market Value.  The cost of the financial  expert
shall be borne equally by the selling party and the purchasing party.

     Section GP Interest  Purchase Option.  In the event that Tejas Energy shall
hereafter  make any  Disposition  of any of the Tejas Units to any Person (other
than a Permitted  Affiliate),  Tejas Energy will promptly provide written notice
to EPC II of such Disposition.  For purposes of this Section 3.2, either (i) the
closing of a transaction (or series of related  transactions)  which result in a
Tejas Change of Control or  (ii) entering  into an agreement the consummation of
which  would  result  in a Tejas  Change  of  Control  shall be  deemed  to be a
Disposition  of all of the Tejas Units.  Tejas Energy shall provide  EPC II with
written notice of a closing described in clause (i) of the preceding sentence at
least ten Business  Days prior to such closing.  EPC II (or its  designee)  will
have the right and option, upon such Disposition,  to purchase from Tejas Energy
a portion of Tejas Energy's member interest in Enterprise GP (the "GP Interest")
equal to such member  interest  (representing a percentage  equity  ownership in
Enterprise  GP)  multiplied  by a fraction  equal to the  number of Tejas  Units
Disposed of by Tejas  Energy over the number of Tejas Units held by Tejas Energy
immediately prior to such Disposition;  provided however,  that in the case of a
Disposition of the type described in clause (ii) of the second  sentence of this
Section 3.2, such right shall be contingent  upon the closing of the transaction
(or series of related  transactions) which effect a Tejas Change of Control. The
purchase  option  afforded  EPC II (or its  designee) in this Section 3.2 may be
exercised  by EPC II (or its  designee)  by  providing  written  notice to Tejas
Energy  of its  election  to  purchase  all of the GP  Interest  subject  to the
purchase option within 30 days following receipt from Tejas Energy of its notice
of  Disposition.  The  purchase  price  payable  following  the exercise of such
purchase option will be an amount equal to the members' capital of Enterprise GP
attributable  to the  purchased  interest  as then  reflected  on the  books and
records of Enterprise GP. The purchase and sale  contemplated by the exercise by
EPC II (or its  designee)  of its  purchase  option  created by this Section 3.2
shall be completed at a closing that shall occur within ten Business  Days after
the written notice by EPC II (or its designee) electing to exercise such option,
by (i) the transfer and  assignment  by Tejas Energy to EPC II (or its designee)
of the GP Interest purchased and (ii) payment of the purchase price described in
the  preceding  sentence  by EPC II (or its  designee)  to Tejas  Energy by wire
transfer of immediately available funds to an account designated by Tejas Energy
at  least  five  Business  Days  prior  to such  transfer  and  assignment.  The
assignment  referred to in the preceding  sentence shall be substantially in the
form attached hereto as Exhibit A.

 Section Enterprise Partners' Right of First Refusal Upon Sale by Tejas Energy.

     In the  event  that  Tejas  Energy  shall  hereafter  desire  to  make  any
Disposition of Tejas Units, in whole or part, or any interest  therein,  that is
not permitted in Section 3.3(f),  Enterprise Partners or its designee shall have
the right and  option to  purchase  all of the Tejas  Units  that  Tejas  Energy
desires to Dispose of,  exercisable  in the manner and on the terms  hereinafter
set forth;  provided however,  that there shall be no obligation of Tejas Energy
to Dispose of such Tejas Units to Enterprise Partners or its designee unless all
of the Tejas Units that are subject to the option to purchase  described in this
Section 3.3 are purchased.  For the purposes of this Section 3.3, either (i) the
closing of a transaction (or series of related  transactions)  which result in a
Tejas Change of

Control or  (ii) entering  into an  agreement  the  consummation  of which would
result in a Tejas Change of Control shall be deemed to be a Disposition by Tejas
Energy of all of the Tejas Units. Tejas Energy shall provide Enterprise Partners
with  written  notice of a closing  described  in  clause (i)  of the  preceding
sentence at least ten Business  Days prior to such closing.  The total  purchase
price for the Tejas  Units  purchased  pursuant  to the  exercise  of any option
granted  by this  Section  3.3 shall be equal to the  number  of Tejas  Units so
purchased times the Section 3.3 Price Per Unit.

     Prior to the  Disposition  of any Tejas  Units,  Tejas  Energy  shall  give
written notice ("Tejas' Notice of Disposition") setting forth:

     the number of Tejas Units that Tejas Energy desires to Dispose of;

     the bona fide cash  price (or  estimated  value of  noncash  consideration,
which  estimate shall not be binding upon  Enterprise  Partners or its designee)
offered in connection with such Disposition of such Tejas Units; and

     the terms  upon which  such  Disposition  is to be made and the name of the
Person or Persons to whom such Disposition is to be made.

     Upon  receipt  by  Enterprise   Partners  of  any  such  Tejas'  Notice  of
Disposition,  Enterprise  Partners (or its  designee)  may exercise its purchase
right as to all (but not less than all) of the Tejas Units being Disposed of for
a period of 30 days  commencing  with the date Tejas' Notice of Disposition  was
received  by  Enterprise  Partners;  provided  however,  that  in the  case of a
Disposition  of the type  described  in clause  (ii) of the second  sentence  of
Section  3.3(a),  such  rights  shall  be  contingent  upon the  closing  of the
transaction (or series of related  transactions)  which effect a Tejas Change of
Control.  Such right to purchase may be exercised by Enterprise Partners (or its
designee)  by giving  notice to Tejas  Energy that  Enterprise  Partners (or its
designee)  has  elected  to  acquire  the Tejas  Units.  The  purchase  and sale
contemplated  by the exercise by  Enterprise  Partners (or its designee) of such
purchase  right shall be  completed at a closing that shall occur within 30 days
after the written  notice by Enterprise  Partners (or its designee)  electing to
exercise such purchase  right (or, if later and if Section  3.3(d)(ii)  applies,
within 15 Business Days after the determination of the Designated Purchase Price
in accordance  with Section  3.1),  by (i) the transfer and  assignment by Tejas
Energy to Enterprise  Partners (or its designee) of certificates,  duly endorsed
for  transfer,  evidencing  the Tejas Units  purchased  and (ii)  payment of the
purchase  price  described  in Section  3.3(a) by  Enterprise  Partners  (or its
designee) to Tejas Energy by wire transfer of immediately  available funds to an
account  designated  by Tejas Energy at least five  Business  Days prior to such
transfer  and   assignment.   Notwithstanding   any  other   provision  of  this
Section 3.3,  if Section 3.3(d)(ii) applies and the Designated Purchase Price as
determined  pursuant to  Section 3.1(ii)  exceeds the estimated value of noncash
consideration  specified by Tejas Energy in Tejas' Notice of Disposition by more
than 10%, then at any time within five  Business  Days after such  determination
Enterprise  Partners  (or its  designee)  shall  have the right to notify  Tejas
Energy that it is electing to cancel its exercise of such purchase right, and in
the case of any such  cancellation,  the 90-day  period  referred  to in Section
3.3(e)  shall  commence  with  the  date of such  cancellation.  The  assignment
referred  to in the  preceding  sentence  shall  be  substantially  in the  form

provided may be completed at any time within,  but not after,  90 days after the
expiration  of the  30-day  period  during  which  Enterprise  Partners  (or its
designee)  may exercise the right to acquire such Tejas Units.  If a Disposition
is not  completed  within  said  90-day  period,  Tejas'  Notice of  Disposition
theretofore  given  shall in all  respects  be a nullity and shall be treated as
though it never had been given.  If such  Disposition  is not carried out on the
same  material  terms set  forth in Tejas'  Notice  of  Disposition  in  respect
thereto,  such  Disposition  shall be of no force,  effect or  validity  for any
purpose whatsoever.

     The  purchase  option in favor of  Enterprise  Partners  (or its  designee)

Energy of the Tejas Units  (i) to a Permitted  Affiliate  or (ii)  pursuant to a
Public Offering.

     Section  Right of  Purchase  in Favor of  Enterprise  Partners  Upon Public
Offering. Offering.

     In the event  that  Tejas  Energy  proposes  to Dispose of any of the Tejas
Units through a Public Offering, Tejas Energy shall first provide written notice
of such proposed  Disposition (the "Public Sale Notice") to Enterprise Partners,
including in such notice a statement of the proposed  public offering price (the
"Proposed Public Offering Price").  Enterprise  Partners (or its designee) shall
have the right and option to purchase  all of the Tejas Units that Tejas  Energy
desires to Dispose of  pursuant  to such  Public  Offering,  exercisable  in the
manner and on the terms hereinafter set forth.

     Upon  receipt  by  Enterprise  Partners  of any such  Public  Sale  Notice,
Enterprise  Partners (or its designee) may exercise its purchase right as to all
(but not less than all) of the Tejas Units subject to the Public Sale Notice for
a period of 20 days commencing with the date the Public Sale Notice was received
by  Enterprise  Partners.  Such right to purchase may be exercised by Enterprise
Partners  (or its  designee)  giving  notice  to Tejas  Energy  that  Enterprise
Partners (or its designee) has elected to acquire the Tejas Units subject to the
Public Sale Notice at the Proposed Public Offering Price.

sentence shall be substantially in the form attached hereto as Exhibit B.

     In the event that Enterprise  Partners does not exercise its purchase right
triggered  by a Public Sale  Notice,  then Tejas Energy may proceed to sell such
Tejas Units pursuant to Public  Offering  provided that such Public  Offering is
completed  within 120 days  following  the end of the 20-day period during which
Enterprise  Partners could exercise its purchase right hereunder,  and the price
at which Tejas Energy sells the Tejas Units in the Public  Offering shall not be

     Section Tejas Energy's  Preemptive  Rights Upon a Private Sale of Interests
by Enterprise Partners.

     In the event  that  Enterprise  Partners  desires  to issue or  Dispose  of
Enterprise Securities other than in a transaction referred to in Section 3.5(f),
Tejas Energy (or a Permitted  Affiliate  designated  by Tejas Energy) shall have
the right and  option to  purchase  its pro rata share  (based on the  aggregate
ownership of Tejas Units and Article IV Units of Tejas  Energy or its  Permitted
Affiliates) of all of the Enterprise Securities that Enterprise Partners desires
to issue or Dispose of,  exercisable in the manner and on the terms  hereinafter
set forth (such pro rata share being  calculated  by  multiplying  the number of
such  Enterprise  Securities  being issued or Disposed of by a fraction equal to
the result of dividing  (i) the  aggregate  number of Tejas Units and Article IV
Units then owned by Tejas Energy or its  Affiliates  by (ii) the total number of
Enterprise  Securities  outstanding on a fully diluted basis without taking into
account the newly issued Enterprise Securities, if any); provided, however, that
there shall be no obligation of Enterprise  Partners to issue or Dispose of such
Enterprise  Securities to Tejas Energy (or a Permitted  Affiliate  designated by
Tejas Energy)  unless all of the Enterprise  Securities  that are subject to the
option to purchase  described in this Section 3.5 are (subject to the provisions
of  subsection  (c) below)  purchased  at the same time and  subject to the same
terms as the other Enterprise  Securities being issued or Disposed of. The total
purchase price for any Enterprise  Securities purchased pursuant to the exercise
of any  option  granted  by this  Section  3.5  shall be equal to the  number of
Enterprise Securities so purchased times the Section 3.5 Price Per Unit.

     Prior  to  the  issuance  or  Disposition  of  any  Enterprise  Securities,
Enterprise  Partners shall give written notice  "Enterprise  Partners' Notice of

Purchase Price as determined  pursuant to Section 3.1(ii)  exceeds the estimated
value of noncash  consideration  specified by Enterprise  Partners in Enterprise
Partners'  Notice of  Disposition by more than 10%, then at any time within five
Business  Days after such  determination  Tejas  Energy  shall have the right to
notify  Enterprise  Partners  that it is electing to cancel its exercise of such

purchased  pursuant to the  exercise of any option  created by this  Section 3.6
shall be equal to the number of units so purchased times the Designated Purchase
Price.

becomes aware of the Enterprise Change of Control,  Tejas Energy (or a Permitted
Affiliate designated by Tejas Energy) may exercise its purchase right to acquire

determination  Tejas Energy shall have the right to notify  Enterprise  Partners
that it is electing to cancel its exercise of such purchase right.

will at its option  either  issue  additional  registered  Common Units to Tejas
Energy,  make a cash payment to Tejas Energy or effect a  combination  of Common
Units and cash payment as follows:

     Enterprise  Partners  may issue to Tejas  Energy  additional  Common  Units
having an aggregate  value  (based on the Closing  Price for Common Units on the
Business Day  immediately  preceding the date of issuance) in an amount equal to
(i) the number of Common  Units so sold by Tejas Energy  multiplied  by (ii) (A)
$18 (as appropriately Adjusted) minus (B) the Sales Price;

     Enterprise  Partners  may  pay  to  Tejas  Energy  an  amount  of  cash  in
immediately  available  funds equal to (i) the number of Common Units so sold by
Tejas Energy multiplied by (ii) (A) $18  (appropriately  Adjusted) minus (B) the
Sales Price; or

                        Any combination of the foregoing.

Notwithstanding  the requirements of clause (iv) of the foregoing,  (i) if Tejas
Energy  requests in writing that  Enterprise  Partners  waive the Manner of Sale
Restrictions  in connection with a proposed sale by Tejas Energy of Common Units
received upon  conversion of Special Units and Enterprise  Partners  declines to
waive the Manner of Sale  Restrictions,  then the one-year period  following the
applicable  Conversion Date for such Common Units will be tolled for such period
during  which  Enterprise   Partners  declines  to  waive  the  Manner  of  Sale
Restrictions,  (ii) in the event  Tejas  Energy  requests a demand  registration
under the  Registration  Rights  Agreement and is prevented from  registering or
trading Common Units as a result of black-out  periods under Section 2(b)(ii) of
the  Registration  Rights  Agreement,  then the one-year  period  following  the
applicable  Conversion  Date for  such  Common  Units  will be  tolled  for such
black-out  period,  (iii) in the event Tejas Energy desires to sell Common Units
in a manner not requiring registration under the Securities Act and Tejas Energy
advises Enterprise Partners of such intention in writing and Enterprise Partners
advises  Tejas Energy in writing that there is material  non-public  information
relating  to  Enterprise  Partners  that  would  prevent  such a sale,  then the
one-year period  following the applicable  Conversion Date for such Common Units
will be tolled for the days  covered by such  advice and (iv) in the event Tejas
Energy  desires to sell Common Units but is restricted  from selling such Common
Units as a result of any lock-up  agreement  binding on Tejas Energy pursuant to
Section 4(a) of the  Registration  Rights  Agreement,  then the one-year  period
following the  applicable  Conversion  Date for such Common Units will be tolled
for such lock-up period.

In the event  Enterprise  Partners is unable or fails to fulfill its obligations
under this Article IV,  EPCO agrees,  if requested in writing by Tejas Energy to
do so, to fulfill the  obligations of Enterprise  Partners under this Article IV
on behalf of Enterprise Partners.

entitled to offer such  business  opportunity  to any Person as such  Management
Designee deems appropriate  under the circumstances in his sole discretion,  and

act in (or not  opposed  to) the  best  interests  of  Enterprise  Partners  and
Enterprise GP or any of their respective  Subsidiaries or the designation of any
improper  personal benefit by reason of the fact that Tejas Energy or any of its
Affiliates  or  Management  Designee in good faith takes any action or exercises
any rights or gives or withholds any consent in connection with any agreement or
contract  between  Tejas  Energy  or  any of its  Affiliates  or any  Management
Designee on the one hand and  Enterprise  Partners and  Enterprise  GP or any of

                                    EXHIBIT D

CODE OF CONDUCT


                                 I. Introduction

This Code of Conduct  describes the general business  principles that govern how
each of the companies which make up the Enterprise  group of companies  conducts
its  affairs,  as  well  as  specific  policies  and  procedures  applicable  to
Enterprise Products Partners L.P, Enterprise Products Operating L.P., Enterprise
Products  Company,   Enterprise  Transportation  Company  and  their  divisions,
affiliates and subsidiaries.

The Enterprise group of companies has widespread activities, and each Enterprise
company has wide freedom of action.  However,  what we all have in common is the
Enterprise reputation.  Upholding the Enterprise reputation is paramount. We are
judged by how we act. Our  reputation  will be upheld if we act with honesty and
integrity  in all our  dealings  and we do what we think  is right at all  times
within the legitimate role of business.

Enterprise  companies have as their core values  honesty,  integrity and respect
for  people.  Enterprise  companies  also  firmly  believe  in  the  fundamental
importance of the promotion of trust, openness, teamwork and professionalism and
pride in what they do.

Our underlying corporate values determine our principles. These principles apply
to all transactions, large or small, and describe the behavior expected of every
employee in every Enterprise company in the conduct of business.

In turn, the application of these principles is underpinned by procedures within
each  Enterprise  company  which are  designed  to make sure that its  employees
understand  the  principles  and  that  they act in  accordance  with  them.  We
recognize that it is vital that our behavior matches our intentions.

All the elements of this  structure--values,  principles  and the  accompanying
procedures--are necessary.

Enterprise  companies  recognize  that  maintaining  the trust and confidence of
unitholders,  employees, customers and other people with whom they do business ,
as well as the  communities  in which they work,  is crucial to their  continued
growth and success.

We intend to merit this trust by conducting ourselves according to the standards
set out in our principles.  These  principles have served  Enterprise  companies
well for many years. It is the  responsibility  of management to ensure that all
employees are aware of these principles and behave in accordance with the spirit
as well as the letter of this statement.

                        II. General Business Principles

1.  Objectives

The objectives of Enterprise  companies are to engage  efficiently,  responsibly
and   profitably   in  the  midstream   natural  gas  liquids,   petrochemicals,
transportation and other selected  businesses.  Enterprise companies seek a high
standard  of  performance  and aim to  maintain a  long-term  position  in their
respective competitive environments.

                                       C-1


2.  Responsibilities

Enterprise companies recognize five areas of responsibility:

         a.  To unitholders

               To protect  unitholders'  investment  and  provide an  acceptable
               return.

         b.  To customers

               To  win  and  maintain  customers  by  developing  and  providing
               products  and  services  which  offer  value in  terms of  price,
               quality,  safety and environmental impact, which are supported by
               the  requisite   technological,   environmental   and  commercial
               expertise.

         c.  To employees

               To respect the human rights of their employees,  to provide their
               employees  with good and safe  conditions  to work,  and good and
               competitive  terms and  conditions  of  service,  to promote  the
               development  and best use of human  talent and equal  opportunity
               employment,  and to encourage the involvement of employees in the
               planning and  direction of their work and in the  application  of
               these  principles  withing their company.  It is recognized  that
               commercial   success  depends  on  the  full  commitment  of  all
               employees.

         d.  To those with whom they do business

               To  seek  mutually  beneficial  relationships  with  contractors,
               suppliers and in joint ventures and to promote the application of
               these  principles  in so doing.  The  ability  to  promote  these
               principles  effectively  will  be  an  important  factor  in  the
               decision to enter into or remain in such relationships.

         e.  To society

               To conduct business as responsible  corporate members of society,
               to observe the laws of the  countries in which they  operate,  to
               express  support for  fundamental  human  rights in line with the
               legitimate  role of business and to give proper regard to health,
               safety and the environment  consistent  with their  commitment to
               contribute to sustainable development.

These  five  areas  are  seen  as  inseparable.  Therefore,  it is the  duty  of
management   continuously   to  assess  the   priorities   and   discharge   its
responsibilities as best in can on the bases of that assessment.

3.  Economic Principles

Profitability  is essential to discharging the  responsibilities  outlined above
and staying in  business.  It is a measure both of  efficiency  and of the value
that customers place on Enterprise products and services. It is essential to the
allocation of the  necessary  company  resources  and to support the  continuing
investment  required to develop  Enterprise  businesses and meet customer needs.
Without profits and a strong financial  foundation,  it would not be possible to
fulfill these responsibilities.


                                       C-2


Enterprise  companies work in a wide variety of changing  social,  political and
economic  environments,  but in general they  believe that the  interests of the
community can be served most efficiently by a market economy.

Criteria for  investment  decisions are not  exclusively  economic in nature but
also take into account social and environmental  considerations and an appraisal
of the security of the investment.

4.  Business Integrity

Enterprise companies insist on honesty, integrity and fairness in all aspects of
their  business and expect the same in their  relationships  with all those with
whom they do business.  The direct or indirect  offer,  payment,  soliciting and
acceptance  of bribes in any form are  unacceptable  practices.  Employees  must
avoid conflicts of interest between their private financial activities and their
part in the conduct of company business.  All business transactions on behalf of
an Enterprise company must be reflected accurately and fairly in the accounts of
the company in accordance with established procedures and be subject to audit.

5.  Political Activities

         a.  Of Companies

               Enterprise  companies act in a socially responsible manner within
               the laws of the  countries  in which  they  operate in pursuit of
               their legitimate commercial  objectives.  Enterprise companies do
               not make payments to political  parties,  organizations  or their
               representatives or take any part in party politics. However, when
               dealing with governments, Enterprise companies have the right and
               responsibility  to make their  position known on any matter which
               affects  themselves,  their  employees,  their customers or their
               unitholders.  They  also have the  right to make  their  position
               known on  matters  affecting  the  community,  where  they have a
               contribution to make.

         b.  Of Employees

               Where  individuals wish to engage in activities in the community,
               including  standing for election to public  office,  they will be
               given the opportunity to do so where this is appropriate in light
               of local circumstances.

6.  Health, Safety and the Environment

Consistent  with their  commitment  to contribute  to  sustainable  development,
Enterprise   companies  have  a  systematic  approach  to  health,   safety  and
environmental management. To this end, Enterprise companies manage these matters
as any other critical business activity.


7.  The Community

The most  important  contribution  that  companies  can make to the  social  and
material  progress of the countries in which they operate is in performing their
basic activities as effectively as possible.  In addition  Enterprise  companies
take a  constructive  interest  in  societal  matters  which may not be directly
related to the business.  Opportunities  for involvement--for example,  through
community, educational or donations programs--will

                                       C-3


vary  depending  on the size of the company  concerned,  the nature of the local
society and the scope for useful private initiatives.

8.  Competition

Enterprise  companies  support free enterprise.  They seek to compete fairly and
ethically and within the framework of applicable competition laws; they will not
prevent others from competing freely with them.

9.  Communications

Enterprise companies recognize that, in view of the importance of the activities
in which they are engaged and their impact on the economies of  communities  and
individuals,   open  communications  are  essential.  To  this  end,  Enterprise
companies  provide relevant  information  about their activities to legitimately
interested  parties,  subject  to  any  overriding  considerations  of  business
confidentiality and cost.

          III. Legal and Ethical Obligations under the Code of Conduct

These obligations are simply stated:

          -    Comply fully with all applicable laws;

          -    Foster an affirmative attitude concerning compliance with the law
               among those reporting to you and among your colleagues;

          -    Demand and exhibit conduct  consistent  with the  expectations of
               the communities in which we operate and necessary to maintain the
               good  reputation  of  Enterprise  for fair,  honest  and  ethical
               conduct; and

          -    Report  any  violation  of our Code of  Conduct  or any threat to
               human health,  safety,  the environment or Enterprise assets that
               you have a good faith reason to believe has occurred or exists to
               your  management  or  your  Human  Resources   representative  as
               discussed under "Reporting Compliance Issues," below.

                         IV. Company Compliance Policies

Most of the Enterprise  compliance policies covering the matters discussed below
are recorded in written documents generally  applicable to all employees and may
be  obtained  from your  Human  Resources  representative.  Others  are  adapted
specifically to certain work areas or to employees  dealing in the areas covered
by the policy. It is the  responsibility of every employee to conduct his or her
job in strict compliance with such policies.  Questions  concerning all policies
may  be  addressed  to  your   immediate   supervisor,   your  Human   Resources
representative  or the  Enterprise  Law  Department.  Enterprise  also  conducts
ongoing  educational  programs  and  training on certain  compliance  issues for
employees.  Because written  policies and training  programs  cannot  anticipate
every  possible  factual  situation,  each  employee has an  obligation  to seek
clarification and advice whenever a question concerning compliance with our Code
of Conduct arises.

1.  Antitrust Laws


                                       C-4


Enterprise's  Antitrust  Compliance  Policy and Antitrust  Compliance  Guide set
forth Enterprise's intention to conduct operations in strict compliance with all
applicable  antitrust  laws.  The antitrust  laws  generally  prohibit  business
activities  that  constitute  unreasonable  restraints  of  trade.  This  policy
discusses the Sherman  Act's  prohibition  against  horizontal  conduct  between
competitors,  such a price  fixing  agreements.  Also  discussed  in the  policy
statement  are the severe  criminal  and civil  penalties,  both  corporate  and
individual,  for violations of the antitrust laws.  Recommendations for avoiding
inadvertent  violations,   including  guidelines  for  discussions  of  business
activities, are also included.

2.  Boycott Laws

Federal law prohibits persons from taking or agreeing to take certain actions in
connection with any  unsanctioned  foreign boycott  directed against any country
friendly to the United States. Enterprise's Compliance with the Foreign Boycotts
Title of the Export  Administration  Act details compliance issues and reporting
requirements.

3.  Conflicts of Interest

Employees have a duty to avoid  situations that might be adverse to Enterprise's
interest or result in conflicting loyalties or interests. Enterprise's Standards
of  Business  Conduct  include   discussions  of  prohibited   involvement  with
suppliers,   contractors,   competitors  or  customers,   prohibited  gifts  and
entertainment and prohibited use of company information.

4.  Drug and Alcohol Abuse

Enterprise  strives to provide  employees  with a workplace  free from substance
abuse (i.e., the illegal or illicit use of drugs and the abuse of alcohol) and a
workplace   where  all   individuals   are  able  to  perform   their   assigned
responsibilities  in a safe and  productive  manner.  Enterprise's  policies  on
Illegal and  Unauthorized  Items at  Operational  Facilities  and in Operational
Vehicles and Illegal and Unauthorized  Items at Home Office and Lodge Facilities
and in Company Passenger Vehicles are part of an extensive program that includes
education, substance abuse identification and testing.

5.  Environment

Proper regard for the environment, consistent with our commitment to sustainable
development,   must  be  an  essential   element  of  all  Enterprise   business
transactions.  Every  employee  has  a  responsibility  towards  ensuring  sound
environmental performance. Enterprise's Policy on Environmental Performance sets
out  Enterprise's  policy for full  compliance with all  environmental  laws and
regulations,  including the  assessment  of  environmental  consequences  before
entering  new  ventures,  activities  or  acquisitions,  as  well  as  fostering
environmental  awareness and  responsibility.  Corporate and individual criminal
and civil liability exists for many violations of environmental laws.

6.  Equal Opportunity

                                       C-5



Enterprise  is fully  committed to a workplace  that is founded on diversity and
equal  opportunity and is free from  discriminatory  action.  In support of this
commitment,    Enterprise's   Equal   Opportunity   Policy   clearly   prohibits
discrimination on the basis of race, color,  religion,  sex, sexual orientation,
national origin, age, physical or mental handicap,  status as a special disabled
veteran or veteran o f the Vietnam era or  citizenship  of  individuals  legally
authorized  to  work  in the  United  States.  Also  prohibited  is any  form of
harassment for any of these reasons.

7.  Export Control

All exports of commodities  and technical data are regulated  under federal law.
Violations  of  export  control  regulations  can  result  in  serious  criminal
penalties to Enterprise  and  individuals.  A summary of the export control laws
and regulations is available through the Enterprise Law Department.

8.  Insider Trading

Federal  securities  laws  prohibit an employee  from  trading in publicly  held
securities,  including those of Enterprise  Products Partners L.P., while in the
possession of material confidential (non-public) information which is learned in
the course of employment.  Faillure to comply with these  requirements  may be a
criminal  offence in many instances.  More detailed  information is contained in
Enterprise's  Insider Trading policy and may be obtained from the Enterprise Law
Department.

9.  Political Contributions and Foreign Corrupt Practices Act

Enterprise  has  adopted a policy  setting  forth the  standard of conduct to be
observed and  procedures  to be followed in all matters  pertaining to political
contributions,   illegal  or  questionable   payments  and  related   accounting
procedures.  Such policy and  related  guidelines  can be found in  Enterprise's
Standards  of Business  Conduct.  The use of  corporate  funds or assets for any
unlawful or improper purpose,  including  payments to governmental  employees or
any other person as a  commercial  bribe ,  influence  payment or  kickback,  is
prohibited.  Specifically discussed are matters dealing with entertainment of or
gifts to government  officials and employees.  As a policy,  Enterprise does not
make payments with corporate funds to political parties or candidates for public
office.  This does not mean,  however,  that  Enterprise will not participate in
public debate.  Enterprise has the right and  responsibility,  in pursuit of its
legitimate  commercial  objectives,  to  make  its  position  known  on  matters
affecting  the  community  if we  have  expertise  and  can  make a  significant
contribution to Enterprise and society.

Enterprise will support  Political Action  Committees  (PACs) in accordance with
applicable  law,  and  employees  are  encouraged  to  make  personal  political
contributions to PACs,  candidates and  organizations of their choice.  However,
any employee who elects to make a personal political  contribution must bear the
entire financial burden of such a contribution.

If any employee wishes to engage in political  activity,  including standing for
election  to public  office,  he or she will be given the  opportunity  to do so
where this is appropriate in light of local circumstances.


                                       C-6


10.  Protection of Assets

Enterprise  has  a  large  variety  of  assets,   including  extremely  valuable
proprietary   information   and  physical   assets.   Enterprise's   proprietary
information includes  intellectual  property and the confidential  business data
entrusted to employees in connection  with their jobs.  Protection of Enterprise
assets  and  third  party  confidential  information  properly  in  Enterprise's
possession is the personal  responsibility  of each  employee.  Further  details
concerning  these  obligations  can be obtained by contacting the Enterprise Law
Department.

11.  Safe Workplace Environment

Enterprise  is fully  dedicated to  maintaining  a workplace  free of recognized
health  and  safety  hazards.   In  this  regard   Enterprise  has  ongoing  and
comprehensive  programs and policies  designed to achieve this policy  objective
and  ensure  full  compliance  with all  applicable  laws and  regulations.  See
Enterprise's Policy on Occupational Safety and Health.

                                       V.  Procedures for Obtaining Guidance

Enterprise  policies  summarized above and numerous specific policies,  training
programs and operating procedures exist for the various jobs at Enterprise. Each
employee is charged  with the  obligation  to  understand  applicable  policies,
procedures  and training made available to him or her. Seek  clarification  from
your supervisors  when necessary.  Managers and supervisors have additional duty
to monitor the continuing adequacy of policies,  procedures and training withing
their areas of responsibility and compliance with our Code of Conduct by persons
reporting to them.

When you have a concern  or are  called  upon to  evaluate  the legal or ethical
correctness of a course of action a result of your employment with Enterprise:

          -    Seek out the appropriate  policy  statement and training  manuals
               and ask your supervisor for clarification when needed.

          -    Don't  debate  alone;  seek the  advice of legal,  environmental,
               human resources and other  administrative  organizations that can
               be of assistance.

          -    As a guide in making your decision,  consider  whether if all the
               facts  surrounding  your  decision  were  published  in the local
               newspaper, you would have any regrets or concerns.

          -    Understand that  Enterprise's  best interests can never be served
               by illegal or unethical conduct and Enterprise will never condone
               it.

Any questions  concerning legal compliance that cannot be answered  promptly and
clearly  should be referred to the Enterprise  Law  Department.  Legal and other
appropriate administrative organizations, working together, will seek to explain
in a practical and readily understandable manner what is require of employees in
order to comply with the law and with Enterprise's ethical requirements.

Our  compliance  policies  and training and our Code of Conduct are all aimed at
avoiding violations of law and unethical conduct.  Our long-term success in this
area will depend on each employee's realizing

                                       C-7


Enterprise's  sincere commitment to these goals,  seeking advice before engaging
in conduct that presents  legal or ethical  questions and obtaining  correct and
unambiguous advice.

                         VI. Reporting Compliance Issues

If an employee has a good faith reason to believe that any violation of our Code
of  Conduct  has  occurred,  he or she is  required  to report  such  violation.
Additionally,  any good faith reason to believe  that a threat to human  health,
safety,  the environment or Enterprise  assets has arisen or exists in or as the
result of conduct in the workplace must be reported promptly.

Reporting  to  your  vice  president,  senior  vice  president,  executive  vice
president or your Human Resources  representative  discharges  this  obligation.
Such  parties have the  responsibility  to see that the  appropriate  Enterprise
management  and, when  compliance  with law issues are raised,  the  appropriate
representatives of the Enterprise Law Department are promptly notified.

Any attempt at retaliation  or  intimidation  against  anyone  reporting in good
faith a suspected  violation of our Code of Conduct or any condition  thought to
constitute a threat to human  health,  safety,  the  environment  or  Enterprise
assets is a serious violation of our Code of Conduct.

                                 VII. Discipline

Enterprise will consistently and  appropriately  enforce the Code of Conduct and
company policies. Discipline will be determined by Enterprise senior management.
Non-compliance  may  result in  discipline  up to and  including  discharge.  In
appropriate  cases or when required by law, law  enforcement  officials  will be
informed of facts discovered by any investigation concerning non-compliance with
the law.
