and in order to protect the Company's interests in the confidential information
of the Company and the business relationships developed by Mr. Robinson with the
clients and potential clients of the Company; and as an additional incentive for
Company to enter into this Agreement, Company and Mr. Robinson agree to the
non-competition provisions of this Article 5. Mr. Robinson agrees that during
the period of Mr. Robinson's non-competition obligations hereunder, Mr. Robinson
will not, directly or indirectly for Mr. Robinson or for others, in any
geographic area or market where Company or Enron or any of their affiliated
companies are conducting the water 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 or
               Company.

These non-competition obligations shall extend until November 9, 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

                                       2
<PAGE>   3

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. Robinson 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. Robinson 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. Robinson 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. Robinson 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. Robinson 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. Robinson; or

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

                                       3
<PAGE>   4

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

     4)   any disclosure of Confidential Information by Mr. Robinson which is
          required by law, including deposition or trial testimony by Mr.
          Robinson pursuant to subpoena. If Mr. Robinson 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. Robinson, Mr.
          Robinson 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. Robinson that time is of the
          essence, Mr. Robinson may obtain legal counsel, and if Mr. Robinson
          and/or his counsel in good faith believe that Mr. Robinson is
          compelled to disclose the Confidential Information or be exposed to
          liability for contempt or suffer other censure or penalty, Mr.
          Robinson may disclose only such Confidential Information to the party
          compelling disclosure as is required by law, as determined by Mr.
          Robinson on advice of counsel. Mr. Robinson 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. Robinson 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.
          Robinson for any other costs and expenses incurred by Mr. Robinson in
          connection with his obligations under this Section 6.1B, including but
          not limited to legal damages and penalties assessed against Mr.
          Robinson for compliance with his obligations hereunder.

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

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.

7.3  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.

     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 ten (10) days after
     such notice is given, the aggrieved party may seek any relief provided in
     this Agreement.

     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

     notice of specific facts of such violation to the other party. If, after

     aggrieved party shall have the right to bring an action at law or in
     equity. In any action brought for an alleged breach of Section 5 or 6.1,
     the complaining party may seek whatever damages and redress it

<PAGE>   6

     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 ten (10) 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.

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

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