     after delivery of such calculation, deliver a notice to Enterprise Partners
     disagreeing  with  Enterprise  Partners'  calculation of the Interim Period
     Adjustment  and setting  forth  Tejas'  calculation  of the Interim  Period
     Adjustment.

          If a notice  of  disagreement  shall  be duly  delivered  pursuant  to
     paragraph (c),  Enterprise  Partners,  Tejas and Tejas Energy shall, during
     the 30 days following such delivery,  use their reasonable efforts to reach
     agreement on the amounts in order to  determine  the final  Interim  Period
     Adjustment.  If, during such period,  Enterprise Partners,  Tejas and Tejas
     Energy are unable to reach such agreement,  they shall promptly  thereafter
     retain  independent  accountants  (a "big 5"  accounting  firm  other  than

     this Agreement and the disputed  amounts for the purpose of calculating the
     final Interim Period Adjustment.  The independent accountants shall deliver
     to Enterprise Partners, Tejas and Tejas Energy, as promptly as practicable,
     a report  setting forth each such  calculation.  Such report shall be final
     and binding upon Enterprise  Partners,  Tejas and Tejas Energy. The cost of
     such review and report shall be borne  equally by  Enterprise  Partners and
     Tejas.

          If the final Interim Period Adjustment is a positive number, then such
     amount will be paid by Tejas or Tejas Energy to Enterprise  Partners within
     ten days following  calculation of the final Interim Period  Adjustment and
     if the final  Interim  Period  Adjustment is a negative  number,  then such

     connection  with any  distribution  of such  securities  as such  terms are
     defined  under the  Securities  Act.  Each of Tejas and  Tejas  Energy  has
     reviewed Enterprise Partners' Annual Report on Form 10-K for the year ended
     December 31, 1998 and Quarterly  Report on Form 10-Q for the quarters ended
     March 31, 1999 and June 30, 1999 (the  "Enterprise  Partners SEC Reports").
     Each of Tejas and Tejas Energy has had an opportunity to discuss Enterprise
     Partners' and Enterprise GP's business and financial condition, properties,
     operations and prospects  with  Enterprise  Partners' and  Enterprise  GP's
     management  and to ask  questions  of officers of  Enterprise  Partners and
     Enterprise GP.

          (b) Tejas and Tejas  Energy  understand  that (i) the Units and the GP
     Interest  will be  "restricted  securities"  under the  applicable  federal
     securities  laws,  (ii) the Securities Act and the rules of the SEC provide
     in  substance  that such  unitholder  may  dispose  of the Units and the GP
     Interest only  pursuant to an effective  registration  statement  under the
     Securities   Act  or  in  a  transaction   exempt  from  the   registration
     requirements  of the  Securities  Act, and (iii) except as set forth in the
     Registration  Rights  Agreement,  Enterprise  Partners has no obligation or
     intention to register the sale of the Units or the GP Interest  pursuant to
     the Securities  Act, and that,  accordingly,  Tejas Energy and Tejas may be
     required to bear the economic  risk of the  investment  in Units and the GP
     Interest for a substantial period of time.

          (c) Tejas and Tejas Energy agree that  certificates  representing  the
     Units  shall be subject to  appropriate  stop-transfer  instructions  to be
     given by Enterprise Partners to its transfer agents and shall have endorsed
     thereon a legend substantially as follows:

               The  securities  represented  by this  certificate  have not been
          registered  under the  Securities Act of 1933, as amended (the "Act"),
          or under any applicable state law, and may not be transferred  without
          registration  under the Act or such  applicable  state  law  unless an
          exemption from such registration is available thereunder.

               Enterprise  Partners agrees to remove such legend at such time as
          the Units are freely tradeable under Rule 144 or otherwise.

     Section  No Brokers.  None of Tejas Energy,  Tejas, the Company nor any of
their respective Subsidiaries or Affiliates has, directly or indirectly, entered
into any agreement with any Person that would  obligate the Company,  any of its
Subsidiaries or any of the Enterprise  Parties to pay any commission,  brokerage
fee or "finder's fee" in connection with the Transactions.

Regulation Sections 301.7701-2 and -3 and any comparable provision of applicable
state or local Tax law that  permits  such  treatment.  Each of the Tejas  Joint
Ventures (other than the Dixie Pipeline  Company) is treated and classified as a
partnership for federal income Tax purposes under Treasury Regulation, Paragraph
301.7701-2 and -3. Each of the Tejas  Co-ownerships is classified and treated as

     extensions of time within which to file) before the Closing Date, have been
     filed,  the  information  provided  in such Tax  Returns  is  complete  and
     accurate in all material respects,  and all Taxes owed by the Company,  its
     Subsidiaries,  the Tejas Joint  Ventures and the Tejas  Co-ownerships  have
     been timely paid in full.

          (c) There are no Liens for Taxes upon the assets of any of the Company
     and its  Subsidiaries or the Tejas  Co-Ownerships,  or, to the Knowledge of
     Tejas or Tejas Energy,  upon the assets of any of the Tejas Joint  Ventures
     (excluding  the  Company's  Subsidiaries),  other  than with  respect to ad
     valorem Taxes which are not yet delinquent or Permitted Liens.  Each of the
     Company  and its  Subsidiaries,  and,  to the  Knowledge  of Tejas or Tejas
     Energy,   each  of  the  Tejas  Joint  Ventures  (excluding  the  Company's
     Subsidiaries)  has fully  complied with all applicable  federal,  state and
     local employment Tax, withholding and contribution obligations with respect
     to its employees,  and all other Tax  withholding  obligations  required by
     law.

          (d) Each of the Company and its Subsidiaries  and, to the Knowledge of
     Tejas  or  Tejas  Energy,  the  Joint  Ventures  (excluding  the  Company's
     Subsidiaries) (or the operators of the Joint Ventures and/or Tejas), to the
     extent  required  by  Section  4081 et seq.  of the Code,  has  obtained  a
     currently effective IRS Form 637 registration number.

restrain,  prohibit,  invalidate,  set  aside,  prevent  or  make  unlawful  any

names (and all derivatives thereof),  trademarks and symbols from the properties
and assets of the Company and its Subsidiaries  (including  changing all signage
relating thereto) and provide the requisite notices to, the appropriate federal,
state or local  agencies  to place the title or other  evidences  of  ownership,
including  operation of the properties and assets, in a name other than any name
of Tejas or any of its Affiliates or any variations thereof. In addition, within
15 days of the actual date of Closing (and 90 days of the actual date of Closing
with respect to Tejas NGL Pipelines,  LLC), Enterprise Operating will change all
of the legal names of the Company and its  Subsidiaries  to delete from the name
thereof the word "Tejas".

     Section   Further Assurances.

          (a) The parties  hereto agree to  cooperate  fully with each other and
     from time to time after the  Closing,  upon  request  and  without  further
     consideration,  to  (i)  execute,  deliver,  acknowledge  and  file  (where
     necessary) all such further instruments,  agreements and documents,  as may
     be  reasonably  required to more  effectively  evidence the transfer of the
     assets  comprising the Business to the Company and its  Subsidiaries  or to
     consummate the  Transactions  and carry out the intent and purposes of this
     Agreement and (ii) take such actions as may be reasonably required to cause
     Enterprise   Operating  (or  its  designee)  to  have  actual  control  and
     possession of the assets  comprising  the  Business.  Without in any manner
     limiting the generality of the foregoing, if record and beneficial title to
     any of the assets comprising the Business is not held by the Company or its
     Subsidiaries but rather is held by an Affiliate of Tejas as of the Closing,
     Tejas  Energy and Tejas agree to execute and to cause their  Affiliates  to
     execute such agreements as shall be reasonably required to cause such title
     to  effectively  be  transferred  and conveyed from Tejas,  Tejas Energy or
     their Affiliates to the Company or its Subsidiaries.

          (b) As to pre-closing  Consents or  governmental  filings  required to
     transfer  the  Business  to the Company or its  Subsidiaries  which are not
     obtained prior to Closing, Tejas

     will (i) designate an in-house  lawyer or business  person (at Tejas' cost)
     to assist  Enterprise  Partners in obtaining  such Consents for a period of
     twelve  months  following  the  Closing,  (ii)  subject  to the  limitation
     contained in subsection (c)  below, will be obligated to provide Enterprise
     Partners  funds to obtain  such  Consents  and (iii)  will,  to the  extent
     possible  (without  any cost to Tejas or its  Affiliates,  which  shall not
     include the loss of such economic  benefit)  provide to the Company and its
     Subsidiaries the economic benefit of such items if the necessary Consent is
     not obtained  within the  above-referenced  twelve month period.  Except as
     provided in this Section 6.05, neither Tejas nor Tejas Energy will have any
     liability for obtaining Consents after the Closing.

          (c)  Tejas'  payments  to  unaffiliated   third  parties  pursuant  to
     paragraphs  (a) and (b) of this Section  6.05 shall not exceed  $500,000 in
     the aggregate;  provided,  however,  that if Tejas or its Affiliates  shall
     incur a cost that exceeds such amount,  in connection  with  undertaking an
     action  requested by  Enterprise  Partners or one of its  Affiliates,  then
     Enterprise Partners and Enterprise Operating shall reimburse such amount to
     Tejas or its Affiliates as the case may be. The cost of the in-house lawyer
     or  business  person  referenced  in  subsection (b)(i)  above  and loss of
     economic benefit pursuant to  subsection (b)(iii)  shall not be included in
     or charged against the $500,000 ceiling.  Tejas,  subject to and as part of
     the  above-referenced  $500,000  ceiling,  agrees to  reimburse  Enterprise
     Partners  for local  counsel  fees  incurred in  connection  with  remedial
     actions pursuant to subsections (a) and (b) above.

     Section    Books and  Records.  Within a  reasonable  period of time  after
Closing, Tejas Energy and Tejas will, and will cause their respective Affiliates
to deliver to  Enterprise  Operating  (or its  designee)  all books,  accounting
records, contracts,  leases, property files and other files and records relating
to the Business.

     Section    Intercompany  Indebtedness.  On or prior to the  Closing,  Tejas
Energy and Tejas shall  (i pay or cause their  Affiliates to pay to the Company
and its  Subsidiaries  all long- term debt  (including  current  maturities) and
other  Indebtedness  for  Borrowed  Money  owed by  Tejas,  Tejas  Energy or any
Affiliate of Tejas or Tejas Energy (other than the Company and its  Subsidiaries
and Joint  Ventures)  as of such date to the  Company and its  Subsidiaries  and
(ii) pay  to  the  Company  a  capital   contribution  and  cause  such  capital
contribution  to be applied  to pay or satisfy  all  long-term  debt  (including
current  maturities)  and other  Indebtedness  for  Borrowed  Money  owed by the
Company  and its  Subsidiaries  to  Tejas,  Tejas  Energy  or  their  respective
Affiliates  (other than the Company and its  Subsidiaries and Joint Ventures) as
of such  date.  Tejas  and  Tejas  Energy  further  agree  to pay  all  Retained
Liabilities when, as and if they become due and payable.

     Section    Excluded  Assets.  On or prior to the  Closing,  Tejas and Tejas
Energy will cause the Excluded  Assets to be transferred and conveyed out of the
Company and its Subsidiaries pursuant to documentation  reasonably acceptable to
Enterprise Partners.

                                       33


     Section    Acts of  Amendment.  Tejas  Energy and Tejas  shall  cause their
Affiliates which conveyed, assigned and contributed assets and properties to the
Company  and  its  Subsidiaries  as  reflected  in  Section  6.09  of the  Tejas
Disclosure  Memorandum to enter into with the Company and its Subsidiaries,  and
shall cause the Company and its  Subsidiaries  to execute an act of amendment to
the  applicable  conveyance  and  assignments  or acts of sale or conveyances as
reflected on Schedule 6.09, effective as of the date of the original conveyance,
assignment and/or contribution.

          (a) After Closing, Tejas and Tejas Energy agree to cause to be paid to
     the Company any amounts received in respect of accounts  receivable related
     to the Business after the Effective Date promptly upon receipt thereof.

          (b) After Closing,  the Enterprise  Parties agree to, and to cause the
     Company and its  Subsidiaries  to, pay to Tejas or Tejas Energy any amounts
     received  in  respect  of the  Excluded  Assets  after the  Effective  Date
     promptly upon receipt thereof.

     Section    Preferential  Rights.  The parties hereto  acknowledge and agree

contemplated by this Agreement,  the Company or any of its Subsidiaries or Tejas
or any of its  Affiliates  is required  to  transfer  title to any of the assets
included in the Business to satisfy a  preferential  right,  then the Company or
its Subsidiary (as the case may be) shall be entitled to receive and retain such
proceeds paid by the Person exercising the preferential right.

     Section    Preparation  of  Historical  Financials.  Tejas and Tejas Energy
agree (at no  out-of-pocket  cost to Tejas or Tejas  Energy) to  cooperate  with
Enterprise  Partners and to provide  Enterprise  Partners with reasonable access
(at all reasonable  times and in a manner so as not to interfere with the normal
business  operations of Tejas and Tejas Energy) to books,  records and personnel
reasonably  required for  Enterprise  Partners to prepare  statements  of direct
operating  revenues and expenses of the Company and its  Subsidiaries for fiscal
years 1996 and 1997 as may be required for  Enterprise  Partners' SEC filings in
connection with the transactions contemplated by this Agreement.

     EPC II  represents  that it (alone and without any other  equity  holder in
Enterprise  Partners)  has the  requisite  ownership in  Enterprise  Partners to
approve the issuance of the Common Units upon  conversion of the Special  Units.
EPC II  covenants  and  agrees  that it will not  dispose  of any of its  equity
interests in Enterprise  Partners prior to such meeting of the  Unitholders  and

the employees of Tejas or its  Affiliates  who are assigned to the Business (the
"Business   Employees"),   which  list  is  attached  hereto  as  Schedule 7.01.
Enterprise  Products shall have the sole and absolute  discretion in determining
which, if any, of the Business Employees it will offer employment and the terms,
conditions and benefits relating to such offers of employment, provided that the
same shall be substantially  comparable with the terms,  conditions and benefits
Enterprise  Products  provides to similarly  situated  employees  of  Enterprise
Products. Employment under such offers shall commence on the later of October 1,
1999, or the date such Business Employee,  if not actively at work on October 1,
1999 for any reason,  excluding vacation, sick leave or regularly scheduled days
off,  returns to full-time  active  employment  with  Enterprise  Products  (the
"Employment  Commencement Date"), provided such Business Employee returns within
180 days of the Closing  Date.  The Business  Employees  who accept and actually
commence  employment  with  Enterprise  Products  are  hereinafter  collectively
referred to as "Transferred Employees."

     Section   Solicitation of Employees.

          (a) Without the prior written  consent of Enterprise  Products,  Tejas
     shall  cause its  Affiliates  to refrain  for a period of one year from the
     Closing Date, from soliciting directly or indirectly,  the employment of or
     otherwise seeking to engage the services of any Transferred Employee. Tejas
     shall be responsible for all obligations and liabilities, if any, under the
     Worker Adjustment and Retraining  Notification Act and any comparable state
     laws with respect to the current and former  Business  Employees who do not
     become Transferred Employees.

          (b)  Without  the  prior  written  consent  of Tejas,  the  Enterprise
     Parties,  Enterprise Products and their respective Affiliates shall refrain
     for a period of one year from the Closing Date, from soliciting directly or
     indirectly, the employment of or otherwise seeking to

HOU04:132863.11
                                       35


     engage  the  services  of any  employee  of Tejas or any of its  respective
     Affiliates, other than the Transferred Employee.

          (c)  Notwithstanding  paragraphs  (a) and (b) of  this  Section  7.02,
     nothing  herein  shall  prevent a party  hereto (the  "Hiring  Party") from
     hiring any employee of another  party  hereto if such person  responds to a
     general   advertisement  of  employment  which  is  not  directed  to  such
     individual  specifically  or  was  otherwise  not  directly  or  indirectly
     solicited by the Hiring Party.

     Section    Employee  Benefit  Plans.   Effective  as  of  their  Employment
Commencement  Dates,  Enterprise  Products  shall  provide  to  the  Transferred
Employees its employee benefit plans and programs ("Enterprise Products' Benefit
Plans") on substantially  the same basis such plans and programs are provided to
similarly situated employees of Enterprise Products,  except that coverage under
Enterprise  Products' group health,  life and disability plans shall commence as
of the Benefit  Plan Date (as defined  below).  With  respect to the  Enterprise
Products'  Benefit  Plans,  Enterprise  Products  shall  grant  the  Transferred
Employees  credit for their service with Tejas Affiliates as of their Employment
Commencement  Date for all purposes  (other than the accrual of benefits under a
defined  benefit  pension  plan) for which such service was  recognized by Tejas
Affiliates under a similar plan or program. With respect to Enterprise Products'
Benefit Plans that provide  group  health,  life and  disability  benefits:  (i)
Enterprise Products shall make Transferred  Employees eligible to participate on
their Employment  Commencement  Date (the "Benefit Plan Date"),  (ii) Enterprise
Products  shall cause such plans to waive any  exclusions  or  limitations  with
respect  to  pre-existing  conditions,   waiting  periods  and  actively-at-work
exclusions,  except to the same extent the Transferred  Employee is subject to a
pre-existing  condition or actively-at-work  exclusion on the Closing Date under
any health plan of Tejas Affiliates, and (iii) Enterprise Products shall provide
that any  health  expenses  incurred  by a  Transferred  Employee  or his or her
covered dependents during 1999 on or before the Benefit Plan Date shall be taken
into account under such plan for purposes of satisfying  applicable  deductible,
coinsurance and maximum  out-of-pocket  provisions.  Enterprise  Products' group
health plan shall be responsible for all benefit claims by Transferred Employees
and their dependents for covered  services  rendered on and after the date their
participation  in  Enterprise  Products'  group health plan  commences,  and the
respective  group health plans of Tejas  Affiliates shall be responsible for all
benefit  claims by  Transferred  Employees  and  their  dependents  for  covered
services  rendered  before their  participation  in Enterprise  Products'  group
health plan commences.

     Section    Vacation.  The Transferred  Employees shall receive credit under
Enterprise  Products'  vacation  schedule  such that the vacation time they earn
with  Enterprise  Products is not less than that which they are eligible to earn
under  the  vacation  schedules  of Tejas  Affiliates  as of the  Closing  Date.
Transferred  Employees  shall be  entitled  to  vacation  time  with  Enterprise
Products  for the  remainder  of 1999 based only on their  actual  service  with
Enterprise  Products,  and  Enterprise  Products'  vacation  schedule  shall  be
prorated  for the  remainder  of 1999 for this  purpose.  Tejas  shall cause its
Affiliates to pay each  Transferred  Employee his or her accrued but unused paid
personal leave as soon as reasonably practicable following the Closing Date.

     Section  Access to Information and Personnel.  (a) After the Closing Date,
Tejas shall cause its  Affiliates  to make  reasonably  available to  Enterprise
Products such financial,  personnel and related information as may be reasonably
requested  by  Enterprise  Products  with respect to any  Transferred  Employee,
including,  but not limited to,  compensation and employment  histories;  except
that neither Tejas nor its Affiliates  will provide any  historical  performance
related data with respect to any Transferred Employee.

     (b) After the Closing Date,  Enterprise  shall make  available to Tejas any
Transferred  Employees with respect to continuing  litigation,  audits and other
reasonable business requests at no cost to Tejas.

     Section   Tejas and Affiliates  Benefit Plans.  (a) Enterprise  Products is
not assuming any employee  benefit plan or program or any liability of Tejas and
its Affiliates  thereunder or any other liability of Tejas or any Affiliate with
respect to any Business Employee or other current or former employee of Tejas or
any Affiliate, including, without limitation, any liability under COBRA.

     (b) Tejas and its Subsidiaries shall cause each Transferred  Employee to be
fully vested as of the Closing  Date in each plan of Tejas and its  Subsidiaries
that is a qualified plan under Section 401(a) of the Code.

     (c) Each Transferred  Employee who would be eligible to immediately  retire
from Tejas and its  Subsidiaries  on the Closing Date and receive retiree health
benefits  under a health  plan of Tejas and its  Subsidiaries  shall be eligible
notwithstanding   his  active  employment  with  Enterprise   Products  and  its
Affiliates to immediately  begin  receiving  retiree health or pension  benefits
under the retiree health plan of Tejas and its Subsidiaries  subject to the then
terms of such plan.

     Section   Third-Party Beneficiaries. No provision of this Article VII shall
create any third-party beneficiary rights in any Transferred Employee (including
any beneficiary or dependent thereof),  including, without limitation, any right
to employment or employment in any particular  position with Enterprise Products
for any specified period of time after the Closing Date.

                                       38


     Section    Indemnification  Procedure.  The party or parties making a claim
for  indemnification  under this Article VIII shall be, for the purposes of this
Agreement,  referred  to as the  "Indemnified  Party"  and the party or  parties
against whom such claims are asserted under this Article VIII  shall be, for the
purposes of this Agreement,  referred to as the "Indemnifying Party." All claims
by any Indemnified  Party under this Article VIII shall be asserted and resolved
as follows:

          (a) In the event that (i) any claim,  demand or Proceeding is asserted
     or  instituted  by any Person  other than the parties to this  Agreement or
     their Affiliates which could give rise to Damages for which an Indemnifying
     Party could be liable to an Indemnified  Party under this  Agreement  (such
     claim, demand or Proceeding, a "Third Party Claim") or (ii) any Indemnified
     Party  under this  Agreement  shall have a claim to be  indemnified  by any
     Indemnifying  Party  under this  Agreement  which does not  involve a Third
     Party Claim (such claim, a "Direct  Claim"),  the Indemnified  Party shall,
     with reasonable promptness, send to the Indemnifying Party a written notice
     specifying the nature of such claim, demand or Proceeding and the amount or
     estimated  amount  thereof  (which amount or estimated  amount shall not be
     conclusive  of  the  final  amount,  if  any,  of  such  claim,  demand  or
     Proceeding)  (a "Claim  Notice"),  provided  that a delay in notifying  the
     Indemnifying  Party  shall  not  relieve  the  Indemnifying  Party  of  its
     obligations under this Agreement except to the extent that (and only to the
     extent  that)  such  failure  shall  have  caused  the  Damages  for  which
     Indemnifying  Party is obligated to be greater than such Damages would have
     been had the Indemnified Party given the Indemnifying Party proper notice.

          (b) In the event of a Third Party Claim, the Indemnifying  Party shall
     be entitled to appoint  counsel of the  Indemnifying  Party's choice at the
     expense of the  Indemnifying  Party to represent the  Indemnified  Party in
     connection  with such  claim,  demand  or  Proceeding  (in  which  case the
     Indemnifying  Party shall not  thereafter be  responsible  for the fees and
     expenses of any separate counsel  retained by any Indemnified  Party except
     as set forth below); provided that such counsel is reasonably acceptable to
     the Indemnified Party.  Notwithstanding an Indemnifying Party's election to
     appoint  counsel to represent an  Indemnified  Party in  connection  with a
     Third  Party  Claim,  an  Indemnified  Party shall have the right to employ
     separate  counsel,  and the  Indemnifying  Party shall bear the  reasonable
     fees, costs and expenses of such separate counsel if (i) the use of counsel
     selected by the Indemnifying Party to represent the Indemnified Party would
     present such  counsel with a conflict of interest or (ii) the  Indemnifying
     Party shall not have employed  counsel to represent the  Indemnified  Party
     within a  reasonable  time after  notice of the  institution  of such Third
     Party Claim. If requested by the Indemnifying  Party, the Indemnified Party
     agrees  to  cooperate  with  the  Indemnifying  Party  and its  counsel  in
     contesting any claim,  demand or Proceeding  which the  Indemnifying  Party
     defends,  or, if appropriate and related to the claim, demand or Proceeding
     in question,  in making any  counterclaim  against the Person asserting the
     Third Party  Claim,  or any  cross-complaint  against any Person.  No Third
     Party  Claim may be settled or  compromised  (i) by the  Indemnified  Party
     without the prior written consent of the Indemnifying  Party, which consent
     shall not be unreasonably  withheld or delayed or (ii) by the  Indemnifying
     Party without the prior written consent of the

HOU04:132863.11
                                       39


     Indemnified  Party,  which  consent shall not be  unreasonably  withheld or
     delayed.  In the event any  Indemnified  Party  settles or  compromises  or
     consents to the entry of any Judgment with respect to any Third Party Claim
     without  the  prior  written  consent  of  the  Indemnifying   Party,  each
     Indemnified  Party  shall be deemed to have  waived all rights  against the
     Indemnifying Party for indemnification under this Article VIII.

          (c) In the  event of a Direct  Claim,  the  Indemnifying  Party  shall
     notify the Indemnified  Party within 30 Business Days of receipt of a Claim

     Indemnifying  Party,  each  Indemnified  Party shall grant the Indemnifying
     Party and its representatives  all reasonable access to the books,  records
     and properties of such Indemnified Party to the extent  reasonably  related
     to the matters to which the Claim Notice relates.  All such access shall be
     granted during normal business hours and shall be granted under  conditions
     which will not  unreasonably  interfere with the business and operations of
     such Indemnified  Party. The Indemnifying Party will not, and shall require
     that its  representatives do not, use (except in connection with such Claim
     Notice) or disclose to any third Person other than the Indemnifying Party's
     representatives   (except  as  may  be  required  by  applicable  Law)  any
     information obtained pursuant to this  Section 8.03(d)  which is designated

     and the representations  and warranties of the Enterprise Parties,  EPC II,

     the Closing until the second anniversary of the Closing Date;

          (b) the  representations  and  warranties of Tejas and Tejas Energy in

     Limitations Date; and

          (c) the  representations  and  warranties of Tejas and Tejas Energy in
     Sections 3.01, 3.02, 3.03, 3.08, 4.01, and 4.11 and the representations and
     warranties of the Enterprise  Parties,  EPC II and  Enterprise  Products in

do not expressly survive the Closing or

HOU04:132863.11
                                       40


after the expiration of the applicable  survival period thereof;  provided that,
with  respect to any  representation  or warranty  that  survives the Closing in
respect  of  which   indemnity  may  be  sought  under  this   Agreement,   such
representation  or warranty  shall survive the time at which it would  otherwise
terminate  pursuant  to the  preceding  sentence,  only if a bona fide,  written
notice of the inaccuracy of such  representation or warranty giving rise to such
right of indemnity (including the specific nature of such inaccuracy) shall have
been given to the party against whom such  indemnity may be sought prior to such
time.  The  covenants  and  agreements  of  the  parties   (including,   without
limitation,  the  covenants  and  agreements  of the  parties  set forth in this
Article VIII) contained in this Agreement or in any other Transaction  Agreement
shall survive the Closing indefinitely.

          (a) Each party  hereto  acknowledges  and agrees  that  (except as set
     forth in subsection (d) below),  the provisions of this Article VIII  shall
     be the  exclusive  remedy of such party with respect to any matter  arising
     under this Agreement;  provided,  however, that (i) the foregoing shall not
     limit the right of any such party to seek any equitable  remedy  (including
     specific  performance)  available to enforce the rights of such party under
     this Agreement or any other  Transaction  Agreement in accordance  with the
     terms of this Agreement and (ii) nothing herein is intended to restrict the

     otherwise arising independently of this Agreement.

          such claims  exceeds  $8,000,000 in the aggregate and then only to the
          extent of the excess over such amount; and

               (ii) The  obligations  and  total  liability  of Tejas  and Tejas
          Energy for such Damages shall not exceed $60,000,000 in the aggregate.

          (d) Nothing in this Section 8.05 shall prevent any party from making a

     Parties following the Closing Date. For purposes hereof, "Tejas Third-Party
     Environmental  Claims"  shall mean (x) a bona fide  claim by a third  party
     (other than a Governmental  Authority  acting in its  regulatory  capacity)

          respect  to  all  Tejas   Third-Party   Environmental   Claims  exceed
          $5,000,000  in the aggregate and then only to the extent of the excess
          over $5,000,000.  Individual Tejas  Third-Party  Environmental  Claims

     Company and the  Subsidiaries)  for Damages resulting out of or relating to
     environmental  claims,  matters or  liabilities  (including  violations  of
     Environmental  Law  and  required  remediation  of  properties  due  to the
     presence of Hazardous Substances in the soil, groundwater or surface water)
     shall be governed  exclusively by the indemnification  provisions contained
     in this Section 8.06.

          (d) With regard to all Tejas  Third  Party-Environmental  Claims,  the
     Enterprise  Indemnified  Parties shall give written notice identifying such

     applicable  Governmental  Authority  concerning  the  remediation  plan  or
     project.

     Payments").  For purposes  hereof,  "Enterprise  Third-Party  Environmental
     Claims'  shall mean (x) a bona fide claim by a third  party  (other  than a
     Governmental   Authority)  alleging  personal  injury  or  property  damage

     of  properties,  now,  previously  or  hereafter,  owned by the  Enterprise
     Parties  or any of their  Subsidiaries;  provided,  however,  that the term

     relating  to  the  properties  or  assets   included  in  the  Business  as
     contemplated by this Agreement.

          Enterprise Parties incur Damages in excess of $500,000 with respect to
          such Enterprise Third-Party Environmental Claim.

     and other  similar  Taxes,  levies,  fees and charges,  if any, that may be
     imposed upon,  or payable or  collectible  or incurred in connection  with,

     received  from the relevant  Tax  authorities)  all Tax Returns  accurately
     reflecting the operations of the Company and its  Subsidiaries  for periods
     ending  prior to the  Closing  Date and shall pay all  Taxes  with  respect

agreements,  or  satisfaction  of any  of  the  conditions,  contained  in  this
Agreement by the other.  Any agreement on the part of a party to this  Agreement
