5 Post-Employment Non-Competition Obligations.

5.1 As part of the consideration for the compensation and benefits to be paid to
Mr. Gray hereunder, in keeping with Mr. Gray's duties as a fiduciary and in
order to protect the Company's interests in the confidential information of the
Company and the business relationships developed by Mr. Gray with the clients
and potential clients of the Company; and as an additional incentive for Company
to enter into this Agreement, Company and Mr. Gray agree to the non-competition
provisions of this Article 5. Mr. Gray agrees that during the period of Mr.
Gray's non-competition obligations hereunder, Mr. Gray will not, directly or
indirectly for Mr. Gray or for others, in any geographic area or market where
Company or any of its affiliated companies are conducting any business as of the
date of termination of the employment relationship or have during the previous
twelve months conducted any business:

         (i)      engage in any business competitive with the water business
                  conducted by Company;

         (ii)     render advice or services to, or otherwise assist, any other
                  person, associations, or entity who is engaged, directly or
                  indirectly , in any business competitively with the water
                  business conducted by the Company; or

         (iii)    induce any employee of Company or Enron Corp. or their
                  affiliates to terminate his or her employment with Company, or
                  their affiliates, or hire or assist in the hiring of any such
                  employee by person, association, or entity not affiliated with
                  Enron Corp.

These non-competition obligations shall extend until February 15, 2004.

5.2 Remedy for Breach of Contract. The parties agree that in the event there is
any breach or asserted breach of the terms, covenants or conditions of this
Agreement, the remedy of the parties hereto shall be in law and in equity and
injunctive relief shall lie for the enforcement of or relief from any provisions
of this Agreement. If any remedy or relief is sought and obtained by any party
against one of the other parties pursuant to this Section 5.2, the other party
shall, in addition to the

                                       2
<PAGE>   3

remedy of relief so obtained, be liable to the party seeking such remedy or
relief for the expenses incurred by such party in successfully obtaining such
remedy or relief, including the fees and expenses of such successful party's
counsel.

5.3 It is expressly understood and agreed that Company and Mr. Gray consider the
restrictions contained in this Article 5 to be reasonable and necessary to
protect the proprietary information of Company. Nevertheless, if any of the
aforesaid restrictions are found by a court having jurisdiction to be
unreasonable, or overly broad as to geographic area or time, or otherwise
unenforceable, the parties intend for the restrictions therein set forth to be
modified by such courts so as to be reasonable and enforceable and, as so
modified by the court, to be fully enforced.

6.  Confidential Information.

6.1 Confidential Information.

         A. Mr. Gray acknowledges that Company's business is highly competitive
and that Company's methods, strategies, books, records and documents, Company's
technical information concerning its products, equipment, services and
processes, procurement procedures and pricing and marketing techniques,
including but not limited to the names of and other information (such as credit
and financial data) concerning Company's customers and business affiliates, all
comprise confidential business information and trade secrets of Company which
are valuable, special, and unique assets of Company, which Company uses in its
business to obtain a competitive advantage over Company's competitors which do
not know or use this information. Mr. Gray further acknowledges that protection
of Company's confidential business information and trade secrets against
unauthorized disclosure and use, is of critical importance to Company in
maintaining its competitive position. Accordingly, Mr. Gray hereby agrees that
notwithstanding any other provision of this Agreement other than contained in
the following paragraph "B", he will not, at any time, make any unauthorized
disclosure of any of the information referred to in the first sentence of this
Section 6.1A ("Confidential Information") or make any unauthorized use thereof
which, in any manner, would have, or is likely to have, an adverse effect upon
the Company or any affiliate.

         B. However, Mr. Gray obligations under this Section 6 shall not extend
to:

         1)       Confidential Information which is or becomes part of the
                  public domain or is available to the public by publication or
                  otherwise without disclosure by Mr. Gray; or

         2)       Confidential Information which was within Mr. Gray's knowledge
                  or in his possession prior to his employment by the Company;
                  or

         3)       Confidential Information which, either prior to or subsequent
                  to the Company's disclosure to Mr. Gray with an obligation of
                  confidentiality, was disclosed to Mr. Gray, without obligation
                  of confidentiality, by a third party who did not acquire such
                  information, directly or indirectly, from Mr. Gray, or from
                  any third party who is under an obligation of confidentiality;
                  or

                                       3
<PAGE>   4

         4)       any disclosure of Confidential Information by Mr. Gray which
                  is required by law, including deposition or trial testimony by
                  Mr. Gray pursuant to subpoena. If Mr. Gray is requested or
                  required (by oral question, interrogatories, request for
                  information or documents, subpoena, civil investigative demand
                  or similar process) to disclose any Confidential Information,
                  if reasonably possible under the circumstances as determined
                  in good faith by Mr. Gray, Mr. Gray will promptly notify the
                  Company of such request or requirement so that the Company may
                  seek an appropriate protective order or waive compliance with
                  provisions of this Agreement. In the absence of a protective
                  order or the receipt of a waiver hereunder, or in the good
                  faith determination of Mr. Gray that time is of the essence,
                  Mr. Gray may obtain legal counsel, and if Mr. Gray and/or his
                  counsel in good faith believe that Mr. Gray is compelled to
                  disclose the Confidential Information or be exposed to
                  liability for contempt or suffer other censure or penalty, Mr.
                  Gray may disclose only such Confidential Information to the
                  party compelling disclosure as is required by law, as
                  determined by Mr. Gray on advice of counsel. Mr. Gray further
                  agrees that he will cooperate with the Company in its efforts
                  to obtain a protective order or other reliable assurance that
                  confidential treatment will be accorded the Confidential
                  Information. All legal fees, costs and expenses incurred by
                  Mr. Gray in obtaining legal representation pursuant to his
                  obligations under this Section 6.1B shall be paid by the
                  Company. The Company further agrees that it will indemnify Mr.
                  Gray for any other costs and expenses incurred by Mr. Gray in
                  connection with his obligations under this Section 6.1B,
                  including but not limited to legal damages and penalties
                  assessed against Mr. Gray for compliance with his obligations
                  hereunder.

6.2 Definition of Company. For purposes of this Agreement, "Company" shall
include Azurix Corp., and all of its subsidiaries and affiliated companies.

6.3 Non-Disparagement. Mr. Gray and Company agree that they will not knowingly
make any comments with the intent to impugn, castigate or otherwise damage the
reputation of the other, including Company's subsidiaries and affiliated
companies, and the executives and managers thereof, unless legally compelled to
do so in any legal or administrative proceeding.

effective only upon receipt.

7.2 Applicable Law. THIS CONTRACT IS ENTERED INTO UNDER, AND SHALL BE GOVERNED
FOR ALL PURPOSES BY, THE LAWS OF THE STATE OF TEXAS.

7.3 No Waiver. No failure by either party hereto at any time to give notice of
any breach by the other party of, or to require compliance with, any condition
or provision of this Agreement shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.

7.4 Remedy for Breach of Contract.

         A. The parties agree that in the event there is any breach or asserted
         breach of the terms, covenants or conditions of this Agreement, the
         remedies of the parties hereto shall be in both law and in equity,
         including injunctive relief for the enforcement of or relief from any
         provisions of this Agreement.

         B. In the event either party has a reasonable basis for claiming that
         the other party has violated the provisions of Section 5 of this
         Agreement and that such violation is material, the aggrieved party
         shall give the other party written notice of the specific facts of such
         violation. If such violation is material and has not been cured within
         three (03) days after such notice is given, the aggrieved party may
         seek any relief provided in this Agreement.

         C. Of Sections 5, 6.1, or 6.3: In the event either party has a
         reasonable basis for claiming that the other party has violated the
         provisions of Sections 5, 6.1, or 6.3 and such violation is material,
         such party shall give written notice of specific facts of such
         violation to the other party. If, after three (03) days of giving such
         notice, the alleged violation has occurred, has not ceased, or
         reasonably may be expected to be repeated again, the aggrieved party
         shall have the right to bring an action at law or in equity. In any
         action brought for an alleged breach of Sections 5, 6.1, or 6.3, the
         complaining party may seek whatever damages and redress it deems
         appropriate, including but not limited to injunctive relief pertaining
         to the alleged violation complained of.

         D. Money damages would not be sufficient remedy for any breach of 6.1
         or 6.3 by either party, and either party shall be entitled to seek
         specific performance and injunctive relief as

                                       5
<PAGE>   6

         remedies for such breach or threatened breach, subsequent to the three
         (03) day period after the notice provided for in Section 7.4C. Such
         remedies shall not be deemed the exclusive remedies for a breach of
         Section 6.1 or 6.3 by either party, but shall be in addition to all
         remedies available at law or in equity to the non-breaching party
         including the recovery of damages from the breaching party, as provided
         for in Section 7.4C.

7.5 Severability. It is a desire and intent of the parties that the terms,
provisions, covenants and remedies contained in this Agreement shall be
enforceable to the fullest extent permitted by law. If any such term, provision,
covenant or remedy of this Agreement or the application thereof to any person or
circumstances shall, to any extent, be construed to be invalid or unenforceable
in whole or in part, then such term, provision, covenant or remedy shall be
construed in a manner so as to permit its enforceability under the applicable
law to the fullest extent permitted by law. In any case, the remaining
provisions of this Agreement or the application thereof to any person or
circumstances other than those to which they have been held invalid or
unenforceable, shall remain in full force and effect. It is further the desire
and intent of the parties that in the event of any breach of any portion of this
Agreement, the remainder of this Agreement shall remain in effect as written and
enforceable to the fullest extent permitted by law.

each of which shall be deemed to be an original, but all of which together will
constitute one and the same Agreement.

payable under this Agreement all federal, state, city or other taxes as may be
required pursuant to any law or governmental regulation or ruling.

convenience and shall not be used for interpretive purposes.

7.9 Assignability.

         A.       By the Company:

                  The Company's obligations under this Agreement are not
                  transferable or assignable by the Company and shall be
                  considered a liability of the Company in any sale or transfer
                  of substantially all of the business or assets of the Company
                  by any means whether direct or indirect, by purchase, merger,

                  conditions of this Agreement, any such assignment shall be
                  subject to the provisions of Section 7.4 of this Agreement.

                  shall be payable to Mr. Gray's estate, and the options
                  described in subsection 2.b. shall remain exercisable by Mr.
                  Gray's beneficiary, or if no beneficiary has been designated
                  for that purpose, by his estate in accordance with the terms
                  and provisions of the 1999 Azurix Corp. Stock Plan and Mr.

               States or the United Kingdom, the tax equalization calculation
               will be updated, and payments made to Mr. Kulpecz or Company (by

5 Post-Employment Non-Competition Obligations.

5.1 As part of the consideration for the compensation and benefits to be paid to
Mr. Kulpecz hereunder, in keeping with Mr. Kulpecz's duties as a fiduciary and
in order to protect the Company's interests in the confidential information of

non-competition provisions of this Article 5. Mr. Kulpecz agrees that during the
period of Mr. Kulpecz's non-competition obligations hereunder, Mr. Kulpecz will
not, directly or indirectly for Mr. Kulpecz or for others, in any geographic
area or market where Company or Enron or any of their affiliated companies are
conducting any business as of the date of termination of the employment
relationship or have during the previous twelve months conducted any business:

          (i)   engage in any business competitive with the water business
                conducted by Company;

          (ii)  render advice or services to, or otherwise assist, any other
                person, associations, or entity who is engaged, directly or
                indirectly , in any business competitively with the water
                business conducted by the Company; or

          (iii) induce any employee of Company or Enron or their affiliates to
                terminate his or her employment with Company, or their
                affiliates, or hire or assist in the hiring of any such employee
                by person, association, or entity not affiliated with Enron.

These non-competition obligations shall extend until September 14, 2001.
Notwithstanding the foregoing, Mr. Kulpecz may assist or participate in the
currently proposed sale of Azurix International's portfolio of projects to an
entity in which Nigel Robinson, or others at the discretion of the Company, acts
as a lead investor or manager.

5.2 Remedy for Breach of Contract. The parties agree that in the event there is
any breach or asserted breach of the terms, covenants or conditions of this
Agreement, the remedy of the parties hereto shall be in law and in equity and
injunctive relief shall lie for the enforcement of or relief from any provisions
of this Agreement. If any remedy or relief is sought and obtained by any party
against one of the other parties pursuant to this Section 5.2, the other party
shall, in addition to the remedy of relief so obtained, be liable to the party
seeking such remedy or relief for the expenses incurred by such party in
successfully obtaining such remedy or relief, including the fees and expenses of
such successful party's counsel.

5.3 It is expressly understood and agreed that Company and Mr. Kulpecz consider
the restrictions contained in this Article 5 to be reasonable and necessary to
protect the proprietary information of Company. Nevertheless, if any of the
aforesaid restrictions are found by a court having jurisdiction to be
unreasonable, or overly broad as to geographic area or time, or otherwise
unenforceable, the parties intend for the restrictions therein set forth to be
modified by such courts so as to be reasonable and enforceable and, as so
modified by the court, to be fully enforced.

6. Confidential Information.

6.1 Confidential Information.

          A. Mr. Kulpecz acknowledges that Company's business is highly
          competitive and that Company's methods, strategies, books, records and
          documents, Company's technical information concerning its products,
          equipment, services and processes, procurement procedures and pricing
          and marketing techniques, including but not limited to the names of
          and other information (such as credit and financial data) concerning
          Company's customers and business affiliates, all comprise confidential
          business information and trade secrets of Company which are valuable,
          special, and unique assets of Company, which Company uses in its
          business to obtain a competitive advantage over Company's competitors
          which do not know or use this information. Mr. Kulpecz further
          acknowledges that protection of Company's confidential business
          information and trade secrets against unauthorized disclosure and use,
          is of critical importance to Company in maintaining its competitive
          position. Accordingly, Mr. Kulpecz hereby agrees that notwithstanding
          any other provision of this Agreement other than contained in the
          following paragraph "B", he will not, at any time, make any
          unauthorized disclosure of any of the information referred to in the
          first sentence of this Section 6.1A ("Confidential Information") or
          make any unauthorized use thereof which, in any manner, would have, or
          is likely to have, an adverse effect upon the Company or any
          affiliate.

                                       4
<PAGE>   5

          B. However, Mr. Kulpecz obligations under this Section 6 shall not
          extend to:

          1)   Confidential Information which is or becomes part of the public
               domain or is available to the public by publication or otherwise
               without disclosure by Mr. Kulpecz; or

          2)   Confidential Information which was within Mr. Kulpecz's knowledge
               or in his possession prior to his employment by the Company; or

          3)   Confidential Information which, either prior to or subsequent to
               the Company's disclosure to Mr. Kulpecz with an obligation of
               confidentiality, was disclosed to Mr. Kulpecz, without obligation
               of confidentiality, by a third party who did not acquire such
               information, directly or indirectly, from Mr. Kulpecz, or from
               any third party who is under an obligation of confidentiality; or

          4)   any disclosure of Confidential Information by Mr. Kulpecz which
               is required by law, including deposition or trial testimony by
               Mr. Kulpecz pursuant to subpoena. If Mr. Kulpecz is requested or
               required (by oral question, interrogatories, request for
               information or documents, subpoena, civil investigative demand or
               similar process) to disclose any Confidential Information, if
               reasonably possible under the circumstances as determined in good
               faith by Mr. Kulpecz, Mr. Kulpecz will promptly notify the
               Company of such request or requirement so that the Company may
               seek an appropriate protective order or waive compliance with
               provisions of this Agreement. In the absence of a protective
               order or the receipt of a waiver hereunder, or in the good faith
               determination of Mr. Kulpecz that time is of the essence, Mr.
               Kulpecz may obtain legal counsel, and if Mr. Kulpecz and/or his
               counsel in good faith believe that Mr. Kulpecz is compelled to
               disclose the Confidential Information or be exposed to liability
               for contempt or suffer other censure or penalty, Mr. Kulpecz may
               disclose only such Confidential Information to the party
               compelling disclosure as is required by law, as determined by Mr.
               Kulpecz on advice of counsel. Mr. Kulpecz further agrees that he
               will cooperate with the Company in its efforts to obtain a
               protective order or other reliable assurance that confidential
               treatment will be accorded the Confidential Information. All
               legal fees, costs and expenses incurred by Mr. Kulpecz in
               obtaining legal representation pursuant to his obligations under
               this Section 6.1B shall be paid by the Company. The Company
               further agrees that it will indemnify Mr. Kulpecz for any other
               costs and expenses incurred by Mr. Kulpecz in connection with his
               obligations under this Section 6.1B, including but not limited to
               legal damages and penalties assessed against Mr. Kulpecz for
               compliance with his obligations hereunder.

6.3 Non-Disparagement. Mr. Kulpecz and Company agree that they will not
knowingly make any comments with the intent to impugn, castigate or otherwise
damage the reputation of the other, including Company's subsidiaries and
affiliated companies, and the executives and managers thereof, unless legally
compelled to do so in any legal or administrative proceeding.

7.2 Applicable Law. THIS CONTRACT IS ENTERED INTO UNDER, AND SHALL BE GOVERNED
FOR ALL PURPOSES BY, THE LAWS OF THE STATE OF TEXAS.

7.3 No Waiver. No failure by either party hereto at any time to give notice of

or provision of this Agreement shall be deemed a waiver of similar or dissimilar
provisions or conditions at the same or at any prior or subsequent time.

7.4 Remedy for Breach of Contract.

          A. The parties agree that in the event there is any breach or asserted
          breach of the terms, covenants or conditions of this Agreement, the
          remedies of the parties hereto shall be in both law and in equity,
          including injunctive relief for the enforcement of or relief from any
          provisions of this Agreement.

                                       6
<PAGE>   7

          B. In the event either party has a reasonable basis for claiming that
          the other party has violated the provisions of Section 5 of this
          Agreement and that such violation is material, the aggrieved party
          shall give the other party written notice of the specific facts of
          such violation. If such violation is material and has not been cured
          within three (03) days after such notice is given, the aggrieved party
          may seek any relief provided in this Agreement, provided, the Company
          may seek termination of the Consulting Arrangement, in addition to any
          other relief that may be appropriate.

          C. Of Sections 5 or 6.1: In the event either party has a reasonable
          basis for claiming that the other party has violated the provisions of
          Sections 5 or 6.1, and such violation is material, such party shall
          give written notice of specific facts of such violation to the other
          party. If, after three (03) days of giving such notice, the alleged
          violation has occurred, has not ceased, or reasonably may be expected
          to be repeated again, the aggrieved party shall have the right to
          bring an action at law or in equity. In any action brought for an
          alleged breach of Sections 5or 6.1, the complaining party may seek
          whatever damages and redress it deems appropriate, including but not
          limited to injunctive relief pertaining to the alleged violation
          complained of.

          D. Money damages would not be sufficient remedy for any breach of
          Section 6.1 by either party, and either party shall be entitled to
          seek specific performance and injunctive relief as remedies for such
          breach or threatened breach, subsequent to the three (03) day period
          after the notice provided for in Section 7.4C. Such remedies shall not
          be deemed the exclusive remedies for a breach of Section 6.1 by either
          party, but shall be in addition to all remedies available at law or in
          equity to the non-breaching party including the recovery of damages
          from the breaching party, as provided for in Section 7.4C.

7.5 Severability. It is a desire and intent of the parties that the terms,
provisions, covenants and remedies contained in this Agreement shall be
enforceable to the fullest extent permitted by law. If any such term, provision,
covenant or remedy of this Agreement or the application thereof to any person or
circumstances shall, to any extent, be construed to be invalid or unenforceable
in whole or in part, then such term, provision, covenant or remedy shall be
construed in a manner so as to permit its enforceability under the applicable
law to the fullest extent permitted by law. In any case, the remaining
provisions of this Agreement or the application thereof to any person or
circumstances other than those to which they have been held invalid or
unenforceable, shall remain in full force and effect. It is further the desire
and intent of the parties that in the event of any breach of any portion of this
Agreement, the remainder of this Agreement shall remain in effect as written and
enforceable to the fullest extent permitted by law.

7.6 Counterparts. This Agreement may be executed in one or more counterparts,
each of which shall be deemed to be an original, but all of which together will
constitute one and the same Agreement.
