ASSIGNMENT
================================================================================

       FUNDING TO TAKE AZURIX CORP. ("AZURIX" OR THE "COMPANY") PRIVATE AT A

                                                              Situation Overview

OVERVIEW OF TERMS
================================================================================

                      OVERVIEW OF GOING PRIVATE TRANSACTION

================================================================================

Investor:                           Enron

Structure:                          Merge an indirect subsidiary of Enron
                                    ("Merger Sub") into Azurix, whereby Azurix
                                    shall continue as the surviving corporation
                                    and the separate corporate existence of
                                    Merger Sub shall cease

Amount of Investment:               We believe approximately $315-$335 million
                                    (one third of 117.3 million shares of common
                                    stock outstanding at a price we believe will
                                    be between $8.00-$8.50 per share)

Type of Investment:                 Cash

Deal Protection Devices:            None

Conversion of Shares:               The exchange ratio of Azurix common shares
                                    into the surviving corporation's common
                                    shares shall be set at approximately 40
                                    million to one (1), so that AWT's 67%
                                    ownership in Azurix will be converted into 2
                                    of the 3 common shares of the surviving
                                    corporation; there will be no fractional
                                    shares of surviving corporation, so public
                                    shareholders will receive the Merger
                                    Consideration in cash instead; the Merger
                                    Consideration will be funded by Enron
                                    through the Merger Sub. Enron, as sole
                                    shareholder of Merger Sub, will, upon the
                                    merger, obtain the third share of surviving
                                    corporation

Board of Directors:                 Enron's right to appoint more than half of
                                    the directors of Azurix is subject to the
                                    continuing right of MWT to have the right to
                                    direct AWT to elect or replace a percentage
                                    of Azurix's directors equal to 50% minus the
                                    percentage of outstanding voting stock held
                                    by persons other than AWT, Enron and its
                                    affiliates

Termination:                        The merger may be abandoned if the Company
                                    Board or the Special Committee recommends a
                                    superior proposal (a bona fide written
                                    acquisition proposal that would provide
                                    greater value to the Company's shareholders
                                    than the cash price they are receiving in
                                    the merger)

Majority of the Minority Approval:  A majority of the publicly held shares cast
                                    either for or against the merger must be
                                    cast for the merger

Indenture:                          To be discussed

SIGNIFICANT TRANSACTION ISSUES
================================================================================

o    PRICING

     o    A potential $8.00-$8.50 price range represents a 124.6%-138.6% premium
          to Azurix's stock price one day prior to the announcement of Enron's
          initial proposal of $7.00 per share on October 27, 2000

          -    In addition, a potential $8.00-$8.50 price range is well above
               the Company's 6-month average trading price of $6.17

     o    A potential $8.00-$8.50 price range represents a $1.00-$1.50 per share
          improvement in price compared to Enron's initial proposal of $7.00 per
          share, or a 14.3%-21.4% increase

     o    Standard valuation analyses suggests a valuation range for Azurix of
          $2.00-$9.00 per share

          -    A potential $8.00-$8.50 price falls near the high end of this
               range

     o    A potential $8.00-$8.50 price range is approximately twice the level
          of three of the four initial indications of interest for an
          acquisition of Azurix which resulted from the marketing process
          conducted by SSB and Merrill Lynch

     o    A potential $8.00-$8.50 price range is also above the $7.00 indicative
          offer from Company A* for an acquisition of Azurix, which was
          withdrawn after substantial due diligence

     o    In February 2000, Consulting Firm A* studied strategic alternatives
          and valued Azurix's business at approximately $4.27 per share. A
          potential $8.00-$8.50 price range represents a 87.4%-99.1% premium to
          Consulting Firm A's* independent valuation

     o    A potential price range of $8.00-$8.50 is also above a $7.00 per share
          price which Enron indicated would not be adequate to sell their shares
          in Azurix

SIGNIFICANT TRANSACTION ISSUES (Cont'd)
================================================================================

o    TIMING

     o    Enron's proposal contemplates a one-step merger transaction between an
          Enron acquisition entity and Azurix

          -    Due to MWT's continued post-transaction equity ownership of
               Azurix through AWT, a short-form merger is not possible

          -    A full SEC review of the proxy statement and the schedule 13E-3
               statement is expected and will likely last six weeks or more

          -    A shareholder meeting to approve the merger would be scheduled
               approximately 30 days subsequent to the mailing date of the proxy

o    The Azurix Senior Notes Indenture (the "Indenture") contains a debt
     incurrence test which would restrict Azurix's ability to consummate a
     merger transaction without restructuring existing debt, unrestricting
     Azurix subsidiaries under the terms of the Indenture, or soliciting
     consents from Senior Notes holders to waive the incurrence test

     -    For the proposed transaction to occur under the Indenture, Azurix must
          be able to issue at least $1 of debt and still meet the Fixed Charge
          Ratio (Consolidated EBITDA/Consolidated Fixed Charges) of 2:1 on an
          LTM basis

     -    Azurix's Consolidated EBITDA for the year ended December 31, 2000, is
          projected to decrease from the prior year and the Fixed Charge Ratio
          is currently estimated to decline to 1.81x absent certain actions
          under review

     -    Management is currently forecasting that Consolidated EBITDA will be
          approximately $28 million less than needed to pass the debt incurrence
          test as of December 31, 2000

     -    To avoid failing the debt incurrence test, Enron has proposed to
          Azurix to convert up to $180 million of Azurix's revolving credit G&A
          Line with Enron into 11% Azurix Preferred Stock; in addition, Azurix
          is reviewing unrestricting one or more of its subsidiaries in order
          pass the debt incurrence test

     -    The following page highlights the estimated Fixed Charge Ratio at
          December 31, 2000 and March 31, 2001 and also highlights various
          alternatives to increase the Fixed Charge Ratio above 2:1

SIGNIFICANT TRANSACTION ISSUES (Cont'd)
================================================================================

o    RISK TO THE PUBLIC WITHOUT A TRANSACTION

     o    Azurix remaining public may entail significant risks for the public
          shareholders

          -    Assuming no asset sales occur, Company financial forecasts
               project no available liquidity by May 2002; the company must have
               access to capital to execute its growth through acquisition
               strategies

          -    Projected growth in the water services segment depends on the
               acquisition and operational integration of targeted companies

          -    The privatizing water concession market is both slow and highly
               competitive

          -    Projected improvement of financial results for Azurix Buenos
               Aires is dependent on approval by the regulator of significant
               tariff increases, improvement in the collection of accounts
               receivable, and realization of water quality, customer growth and
               asset expansion goals

          -    The Madera Water Bank project is contingent upon securing the
               necessary environmental permits

o    RISK TO ENRON WITHOUT A TRANSACTION

     o    Enron has strong incentives to consummate the merger

          -    The merger allows Enron to avoid taking a substantial future
               write-down of its investment in Azurix (as much as $1.0 billion)

          -    Enron wants to remove Azurix from the scrutiny of the public
               financial markets so that assets can be sold in a more managed
               and orderly manner rather than in a fire sale

          -    Azurix's performance since the IPO tarnishes Enron's reputation

          -    Enron may be able to use Azurix's losses to optimize tax
               efficiency (i.e., Latin America)

FORMATION OF AZURIX IN 1998
================================================================================

o    ENRON CREATED AZURIX IN 1998 TO CAPITALIZE ON OPPORTUNITIES FOR GROWTH IN
     THE GLOBAL WATER INDUSTRY

o    THE COMPANY BELIEVED THAT IT WAS STRATEGICALLY POSITIONED TO GAIN SHARE IN
     A FRAGMENTED GLOBAL WATER INDUSTRY WHICH WAS PREDICTED TO EXPAND RAPIDLY
     DUE TO PRIVATIZATION OF WATER ASSETS, PENT UP DEMAND FOR INFRASTRUCTURE
     SPENDING AND STRICTER WATER QUALITY AND ENVIRONMENTAL STANDARDS

o    THE STRATEGIC RATIONALE WAS TO TRANSFER ENRON SKILLS TO AZURIX TO PUT THE
     NEW COMPANY IN A UNIQUE POSITION TO CREATE VALUE

     o    Transaction identification and evaluation

     o    Experience in privatizing and deregulating markets

     o    Development and management of international infrastructure projects

     o    Expertise in capital markets

o    IN OCTOBER 1998, AZURIX ACQUIRED WESSEX WATER LTD. FOR $2.4 BILLION

     o    Wessex is the Company's largest acquisition to date and its largest
          asset

     o    Azurix paid 1.5x-1.6x Regulatory Asset Base ("RAB") for Wessex - a
          multiple that was at the high end of the historical valuation range
          for the acquisition of U.K. water companies

     o    Wessex was expected to provide a base off of which to build a global
          water business

o    IN DECEMBER 1998, ENRON CONTRIBUTED AZURIX TO AWT

     o    Simultaneously, MWT acquired a 50% voting interest in AWT for $1.149
          billion

EXPANSION OF AZURIX IN 1999
================================================================================

o    IN JUNE 1999, AZURIX COMPLETED ITS INITIAL PUBLIC OFFERING OF 36.6 MILLION
     SHARES OF COMMON STOCK AT $19.00 PER SHARE

     o    Azurix sold 17.1 million shares and AWT sold 21.5 million shares of
          Azurix common stock (including an over-allotment)

     o    Since the IPO, Enron and MWT has each continued to own a 50% voting
          interest in AWT, which owns approximately 67% of the Company's common
          stock

o    AFTER THE IPO, AZURIX USED THE PROCEEDS TO IMPLEMENT A GROWTH STRATEGY
     FOCUSED ON ACQUISITIONS OF WATER AND WASTEWATER COMPANIES AND WATER
     SERVICES COMPANIES

o    IN JULY 1999, THE COMPANY ACQUIRED A 30-YEAR WATER AND WASTEWATER
     CONCESSION IN THE PROVINCE OF BUENOS AIRES, ARGENTINA, FOR $438.6 MILLION

     o    As part of the concession contract, Azurix must meet water quality,
          service, and infrastructure expansion goals which will require
          significant capital expenditures

     o    The Buenos Aires concession, the company's second largest asset, has
          faced numerous problems since the acquisition including incomplete
          customer accounts, difficulties in accounts receivable collection,
          water quality issues and disputes over tariffs

o    DURING THE COURSE OF 1999, AZURIX ALSO MADE SEVERAL OTHER SMALLER
     ACQUISITIONS, INCLUDING:

     o    A long-term water and wastewater concession in Cancun, Mexico for $14
          million

     o    Azurix North America, a water and wastewater services company with
          operations in 9 U.S. states and in Canada, for $118 million

     o    A 49% interest in Industrias del Agua, S.A. de C.V. (IASA), which
          participates in water and wastewater projects and service provision in
          Mexico, for $23 million

     o    Azurix Brazil RDM, a services company that provides water drilling,
          water supply, and water and wastewater treatment services in Brazil,
          for $57 million

     o    Lurgi Bamag, an international water and wastewater engineering
          services company, for $31 million

EXPANSION OF AZURIX IN 1999 (Cont'd)
================================================================================

o    BY THE END OF 1999, AZURIX'S STRATEGY OF GROWTH THROUGH ACQUISITIONS BEGAN
     TO SLOW

     o    The Company faced disappointing results in Buenos Aires, a 12% tariff
          reduction at Wessex Water, and a declining stock price

     o    Opportunities to acquire concessions through privatizations developed
          more slowly than expected

     o    For the major water concessions that did come available, larger
          international water companies such as Vivendi and Suez Lyonnaise
          outbid Azurix

          -    Azurix was at a disadvantage in bidding for large concessions
               because its cost of capital was significantly higher than
               competitors such as Vivendi and Suez Lyonnaise (approximately
               9%-10% for Azurix vs. 6%-7% for competitors)

o    AS A RESULT OF THESE DEVELOPMENTS, AZURIX DECIDED TO SCALE BACK ITS GROWTH
     PROGRAM SIGNIFICANTLY IN THE FOURTH QUARTER OF 1999

     o    After announcing its intentions to Wall Street on an earnings call,
          the Company's stock price began to suffer dramatically

o    THE COMPANY TOOK A $35 MILLION RESTRUCTURING CHARGE AS IT REORIENTED THE
     BUSINESS STRATEGY GOING FORWARD

     o    Corporate and Azurix Services staff was reduced from 270 to 170 people

     o    Several offices were closed or reduced

     o    Global activities in areas such as Asia, Africa and South America were
          scaled back

o    THE NEW STRATEGY FOCUSED ON OPTIMIZATION OF THE COMPANY'S EXISTING ASSET
     BASE THROUGH OPERATIONAL IMPROVEMENTS AND ON SMALLER, SYNERGISTIC GROWTH
     OPPORTUNITIES WITH QUICK PAYBACKS

     o    Service focus rather than capital intensive concession focus

LIQUIDITY ISSUES
================================================================================

o    IN FEBRUARY 2000, AZURIX ISSUED U.S. DOLLAR AND U.K. POUND STERLING NOTES
     WITH A U.S. DOLLAR EQUIVALENT FACE VALUE OF $599.8 MILLION

     o    The senior notes consisted of $240 million and 100 million due in 2007
          at an interest rate of 10 3/8% and $200 million due in 2010 at 10 3/4%

     o    Net proceeds were $583.1 million, of which $150.0 million was used to
          pay down the Company's revolving credit facility, $386.0 million to
          pay down the Azurix Europe Ltd. ("AEL") revolving credit facility,
          $18.1 million to pay down amounts outstanding under the credit
          agreement with Enron, and $11.5 million to pay accrued interest on the
          three credit facilities

     o    The remaining proceeds were available for general corporate purposes

o    THE COMPANY IS EXPECTED TO REMAIN CAPITAL CONSTRAINED DURING THE FINANCIAL
     FORECAST PERIOD DUE TO HIGH LEVERAGE, PROJECTED NEGATIVE CASH FLOW, AND A
     LOW COMMON STOCK PRICE

     o    The Company will utilize two primary sources of available capital in
          order to fund its negative cashflow requirements:

          -    $180 million credit line from Enron ("Enron Line") for general
               and administrative expenses (domestic)

          -    $640 million (L.425 million) AEL revolving credit facility
               consisting of two tranches: The first tranche ($280 million)
               relates to prior acquisition financing (original Wessex
               acquisition) while the second tranche ($360 million) is a
               revolving line which can be used to fund growth within the entire
               Azurix organization (European and non-European operations)

     o    Due to the capital intensive nature of Azurix's operations, the
          Company is projected to be cash flow negative for the Company's
          financial forecast period

     o    Based on these forecasts, and barring asset sales by Azurix, the
          Company would not have sufficient free cash flow or borrowing capacity
          to repay the Enron Line in December 2001; Enron would need to renew or
          restructure the Enron Line

     o    Azurix management is optimistic that the AEL revolver could be
          refinanced in May 2002 but insufficient borrowing capacity would
          remain to fund forecasted negative cash flow

     Assumes Lurgi and RDM operations are shut down. Assumes all sales occur
     tax-free

(2)  Assumes asset sale proceeds repay AEL Revolver first, and then the Enron
     Line. Based on the above divestiture analysis, Azurix would still need
     Enron to role its G&A Line

STRATEGIC PROCESS IN 2000
================================================================================

o    AZURIX WAS INITIALLY CONTACTED BY COMPANY A* AT THE END OF 1999 ABOUT A
     POSSIBLE SALE AND DISCUSSIONS WERE HELD IN JANUARY 2000

     o    Discussions then broke off for several months as Company A* completed
          a merger and a review of its water strategy

o    IN FEBRUARY 2000, CONSULTING FIRM A* STUDIED STRATEGIC ALTERNATIVES AND
     VALUED AZURIX'S BUSINESS

     o    The study placed a discounted cash flow valuation of approximately
          $500 million, or $4.27 per share, on all of Azurix

o    AS A RESULT OF THE FOLLOWING KEY FACTORS, AZURIX MANAGEMENT MADE A
     RECOMMENDATION TO THE BOARD OF DIRECTORS TO SEEK AN ACQUIRER OR STRATEGIC
     INVESTOR:

     o    Highly leveraged balance sheet

     o    Insufficient liquidity to fund projected negative cash flow through
          2002

     o    Depressed stock price

     o    Difficulty in pursuing concessions and acquisitions with limited
          access to capital

o    IN EARLY MARCH, THE BOARD OF DIRECTORS OF AZURIX AUTHORIZED IMPLEMENTATION
     OF A TARGETED SEARCH FOR STRATEGIC PARTNERS OR ACQUIRORS

o    IN MARCH 2000, AZURIX ENGAGED SSB (THROUGH SSB'S PREDECESSOR, SCHRODERS)
     AND MERRILL LYNCH AS ADVISORS TO EXPLORE STRATEGIC OPTIONS FOR THE COMPANY

STRATEGIC PROCESS IN 2000 (Cont'd)
================================================================================

o    ON AUGUST 25, AZURIX RECEIVED A LETTER FROM COMPANY A* CONTAINING AN
     INDICATIVE CASH OFFER OF $7.00 PER SHARE, SUBJECT TO DUE DILIGENCE, AND
     REQUESTING AN 8-WEEK EXCLUSIVITY PERIOD

     o    Enron responded by letter on September 13 on behalf of Azurix with a
          detailed 4-week due diligence schedule

     o    In that letter, Enron also expressed concern over the indicated offer
          price of $7.00 per share

o    ALSO ON AUGUST 25, REBECCA MARK RESIGNED FROM THE COMPANY AS CEO

     o    Based on the number of articles and press releases discussing Mark's
          departure and the uncertain future of Azurix, several additional
          parties emerged and expressed limited interest in the Company

o    THE FOLLOWING COMPANIES APPROACHED ENRON FOLLOWING MARK'S DEPARTURE IN
     AUGUST

     o    Company G* met with Enron and Azurix representatives on August 19 and
          made an oral indication of $4.00 per share, but withdrew in late
          September due to concerns about the Company's high leverage

     o    Company H* approached the company in late September but quickly backed
          away, citing Azurix's high leverage and the size of a deal

     o    Other contacts were made with Companies I, J and K*; both Company I*
          and Company J* gave oral indications of interest at or below Azurix's
          market price at the time, which was approximately $4.00 per share

o    ON OCTOBER 13, COMPANY C* SENT A LETTER TO AZURIX STATING ITS INTEREST IN
     JUST WESSEX WATER LTD. AND LURGI BAMAG WITH AN INDICATION THAT IT WOULD BE
     IN A POSITION TO MAKE A PRELIMINARY OFFER BY THE END OF OCTOBER

     o    No further correspondence has occurred

     o    After completing their due diligence, Company A* failed to respond to
          either Enron or Azurix by the October 16 deadline which was
          established in the initial due diligence schedule

     o    Company A* informed Enron orally on October 25 that it would not
          pursue a deal with Azurix

     o    Company A* cited the following reasons for abandoning its offer:

          --   History of company and its stock price

          --   Complicated debt structure

          --   Negative cash flow

          --   Recently filed IPO litigation

o    ON OCTOBER 27, ENRON SENT A LETTER TO AZURIX STATING ITS OFFER TO PROVIDE
     FUNDING TO THE COMPANY TO TAKE ITSELF PRIVATE

     o    The Enron letter and Azurix's related press release were filed with
          the Securities and Exchange Commission as exhibits in a Form 8-K:
          accordingly, the possibility of a sale to Azurix has been publicly
          known for over a month

     o    The Company's Board of Directors formed a Special Committee to
          consider the proposal

     o    In early November, the Special Committee hired WP&Co. and SSB as
          financial advisors to render opinions as to the fairness of the
          proposal

o    A CLASS ACTION LAWSUIT ON BEHALF OF AZURIX'S PUBLIC SHAREHOLDERS WAS FILED
     ON OCTOBER 27 AGAINST THE COMPANY, THE MEMBERS OF THE BOARD, AND ENRON FOR
     THE PURPOSE OF ENJOINING THE PROPOSED TRANSACTION

     o    Several similar actions have subsequently been filed

STRATEGIC PROCESS IN 2000 (Cont'd)
================================================================================

o    ON NOVEMBER 16, COMPANY L*, A U.K.-BASED PRIVATE INVESTMENT FIRM, SENT A
     LETTER TO AZURIX EXPRESSING ITS INTEREST IN WESSEX WATER AND GIVING AN
     INDICATIVE VALUATION OF 95% OF RAB

     o    On November 30, Company L* was contacted by SSB and WP&Co. to discuss
          its expression of interest

     o    SSB and WP&Co. indicated that the indicative valuation was low
          relative to the value implied for Wessex by the Enron funded buyout
          price of $7.00 per share for Azurix and the strategic premiums paid
          for other U.K. water companies

     o    Company L* indicated it could not pay a strategic premium for Wessex

o    ROTHSCHILD (COMPANY A'S* ADVISOR) CONTACTED SSB AND WP&CO. DURING THE WEEK
     OF NOVEMBER 20 ON BEHALF OF COMPANY A*

     o    The contact did not result in any renewed expression of interest

     o    On December 1, WP&Co. spoke with a representative of Rothschild:

          -    To confirm Enron's version of events relating to Company A's*
               withdrawal from the Azurix sale process

          -    To confirm that Company A* would not provide a revised expression
               of interest with respect to a possible acquisition of Azurix

          -    WP&Co. also requested through Rothschild to speak directly with
               Company A* to inquire about Company A's* interest in acquiring
               pieces of Azurix and possible valuation levels for such pieces

       o On December 4, the Rothschild representative called back and said:

          -    Company A* would not provide a revised expression of interest

          -    Company A* might (though there was no assurance) seek to purchase
               assets following the consummation of the Enron proposal, however
               the Rothschild representative was emphatic that Company A's*
               valuation of individual assets would not imply a price for the
               entire Azurix business of greater than $7.00 per share

POSSIBLE STRATEGIC OPTIONS FOR THE SPECIAL COMMITTEE
================================================================================

                      -------------------------------------
                      POTENTIAL SPECIAL COMMITTEE RESPONSES
                           TO THE PROPOSAL FROM ENRON
                      -------------------------------------


                                   DECLINE TO
                               RECOMMEND AN OFFER

o    May be best option if either shareholder value is maximized by pursuing the
     existing business plan or the proposal is not fair and cannot be improved
     to a fair level

o    Potentially prevents a loss of shareholder value

o    Enron may still be able to pursue its offer leaving the public the ability
     to decide

                               ACCEPT A POTENTIAL
                              $8.00-$8.50 PROPOSAL

o    Gives shareholders immediate liquidity

o    Removes Azurix common stock from Wall Street's scrutiny, freeing management
     to realize its strategic plan

o    Probably the easiest transaction to complete

o    A potential price range of $8.00-$8.50 reflects an improvement from Enron's
     initial offer of $7.00

o    However, precludes public shareholders from any potential benefit of a
     turnaround in Azurix's financial results

                         NEGOTIATE TO IMPROVE THE PRICE
                            AND/OR OTHER TERMS OF A
                         POTENTIAL $8.00-$8.50 PROPOSAL

o    Increases shareholder value and gives shareholders immediate liquidity

o    However, Enron is unlikely to further improve its offer above a potential
     $8.00-$8.50 price range

o    Same benefits as accepting the proposal plus greater value for shareholders


                             RECOMMEND OTHER BOARD
                               ACTION TO MAXIMIZE
                               SHAREHOLDER VALUE

o    Explore a sale of Azurix to a third party other than Enron

     --   Enron senior management has indicated that Enron would not sell at
          $7.00

     --   May be difficult given approaches that have already been made

o    Requires determination of available alternatives and the consequences of
     each

     --   Pursuit of Company's existing business plan

     --   Share repurchase

     --   Asset sales

     --   Acquisitions

DECLINE TO RECOMMEND AN OFFER
================================================================================

                                      PROS
--------------------------------------------------------------------------------

o    ALLOWS COMPANY TO PURSUE ITS EXISTING BUSINESS PLAN

     o    North American services business still in early stage of development

     o    Madera Water Bank and the rest of the RDM business have upside
          potential

o    POTENTIALLY PREVENTS A LOSS OF SHAREHOLDER VALUE

o    AFFORDS COMPANY OPPORTUNITY TO IMPLEMENT TURN-AROUND STRATEGY AT BUENOS
     AIRES AND RECOUP VALUE THERE


                                      CONS
--------------------------------------------------------------------------------

o    EXISTING BUSINESS PLAN DOES NOT PROJECT A QUICK IMPROVEMENT IN
     PROFITABILITY

o    THE COMPANY MAY FACE SERIOUS LIQUIDITY ISSUES WITHIN 12 TO 18 MONTHS AS A
     STAND-ALONE ENTITY

o    SHARE PRICE LIKELY TO DROP IN NEAR-TERM IF THE BOARD DECLINES TO RECOMMEND
     AN OFFER

o    AS A SMALL, CAPITAL-CONSTRAINED COMPANY, AZURIX IS AT A COMPETITIVE
     DISADVANTAGE IN THE GLOBAL WATER INDUSTRY

o    MAY BE DIFFICULT TO REALIZE MORE THAN $8.00-$8.50 PER SHARE OF VALUE FROM
     AZURIX IN THE FUTURE

================================================================================

                                        PROS
--------------------------------------------------------------------------------

o    GIVES SHAREHOLDERS IMMEDIATE LIQUIDITY

o    PROBABLY THE EASIEST TRANSACTION TO COMPLETE

o    COMPANY A'S* INDICATIVE OFFER OF $7.00 PER SHARE (WHICH WAS LATER WITHDRAWN
     SUBSEQUENT TO DUE DILIGENCE) HAS BEEN THE ONLY OFFER COMPARABLE TO ENRON'S
     POTENTIAL PROPOSAL

o    A POTENTIAL PRICE RANGE OF $8.00-$8.50 REPRESENTS APPROXIMATELY A 124%-138%
     PREMIUM OVER AZURIX'S PRICE AT THE TIME OF ENRON'S INITIAL OFFER

o    A POTENTIAL $8.00-$8.50 PRICE RANGE ALREADY REPRESENTS A SIGNIFICANT
     IMPROVEMENT FROM ENRON'S INITIAL OFFER OF $7.00

o    BECAUSE OF THE MAJORITY OF THE MINORITY PROVISION, PUBLIC SHAREHOLDERS HAVE
     THE ABILITY TO CHOOSE WHETHER OR NOT TO ACCEPT THE PROPOSAL


                                 CONS
--------------------------------------------------------------------------------

o    PRECLUDES PUBLIC SHAREHOLDERS FROM ANY POTENTIAL BENEFIT OF A TURNAROUND IN

o    SHAREHOLDERS WHO PURCHASED THEIR SHARES ABOVE A POTENTIAL $8.00-$8.50 PRICE
     RANGE MAY BE DISSATISFIED WITH THE OUTCOME

PROPOSAL
================================================================================


                                        PROS
--------------------------------------------------------------------------------

o    INCREASES SHAREHOLDER VALUE AND GIVES SHAREHOLDERS LIQUIDITY

o    SIMILAR BENEFITS AS ACCEPTING THE CURRENT PROPOSAL

o    SUPPORT OF THE ENRON OFFER BY THE SPECIAL COMMITTEE SHOULD BE IMPORTANT TO
     ENRON


                                        CONS
--------------------------------------------------------------------------------

o    A POTENTIAL $8.00-$8.50 PRICE RANGE ALREADY REPRESENTS A SIGNIFICANT
     IMPROVEMENT FROM ENRON'S INITIAL OFFER

o    RUNS THE RISK OF HAVING ENRON WITHDRAW ITS OFFER

o    IF ENRON AND THE SPECIAL COMMITTEE ARE UNABLE TO REACH AGREEMENT AND THE
     PROPOSAL IS WITHDRAWN, AZURIX'S STOCK PRICE WILL LIKELY SUFFER IN THE
     SHORT-TERM

o    PROLONGING THE TRANSACTION PROCESS BY NEGOTIATING MAY COMPLICATE AZURIX'S
     ABILITY TO CONSUMMATE A MERGER TRANSACTION, WITH ANY PARTY, WITHOUT
     RESTRUCTURING EXISTING DEBT, UNRESTRICTING CERTAIN SUBSIDIARIES, OR
     SOLICITING CONSENTS FROM SENIOR NOTES HOLDERS TO WAIVE THE ISSUANCE TEST

     o    Absent certain actions under review, the EBITDA to interest coverage
          ratio is projected to fall below 2:1 for the four quarters ending
          December 31, 2000, and to decline further for the four quarters ending
          March 31, 2001

     o    However, Enron is prepared to provide a certain level of commitment to
          equitize existing loans between Enron and Azurix to meet the
          incurrence test

     o    If the merger approval date is delayed beyond March 31, 2001, the
          additional debt restructuring required to meet the incurrence test may
          be unattractive to Enron

================================================================================

                                        PROS
--------------------------------------------------------------------------------

o    COULD MAXIMIZE SHAREHOLDER VALUE

o    PROCEEDS FROM ASSET SALES MAY GIVE AZURIX THE CASH AND TIME IT NEEDS TO
     SUCCESSFULLY IMPLEMENT ITS TURNAROUND STRATEGY

o    VALUE OF AZURIX TO A STRATEGIC BUYER IN THE WATER INDUSTRY MAY BE GREATER
     THAN TO ENRON

o    THE COMPANY HAS RECENTLY RECEIVED INDICATIONS OF INTEREST IN CERTAIN ASSETS
     FROM POTENTIAL BUYERS


                                      CONS
--------------------------------------------------------------------------------

o    AZURIX HAS ALREADY TRIED THIS APPROACH IN 2000 AND DID NOT RECEIVE ANY
     OFFERS SUPERIOR TO ENRON'S PROPOSAL

o    ASSET SALES MAY WEAKEN AZURIX'S REMAINING BUSINESS AND ONLY TEMPORARILY
     DELAY ITS LIQUIDITY ISSUES

o    THE COMPANY AND ITS FINANCIAL ADVISORS HAVE ALREADY APPROACHED A BROAD
     RANGE OF POTENTIAL BUYERS THIS YEAR SO IT WILL BE DIFFICULT TO GENERATE
     INTEREST NOW

o    AZURIX DOES NOT PROJECT SUCH A RAPID TURNAROUND THAT IT COULD REALIZE
     HIGHER VALUES FOR ASSET SALES IN THE NEAR TERM

o    ENRON CAN EFFECTIVELY BLOCK ANY TRANSACTION IT DOES NOT SUPPORT

                                December __, 2000


Special Committee of the Board of Directors
Azurix Corp.
333 Clay Street
Suite 1000
Houston, TX  77002

Members of the Special Committee:

            You have asked us to advise you with respect to the fairness, from a
financial point of view, to the stockholders of Azurix Corp., a Delaware
corporation (the "Company"), other than Atlantic Water Trust, a Delaware
business trust ("AWT"), and its affiliates (such stockholders other than AWT and
its affiliates, the "Public Stockholders"), of the Merger Consideration (as
defined below) provided for pursuant to the terms of the Agreement and Plan of
Merger, dated as of December __, 2000 (the "Merger Agreement"), by and among the
Company, Enron Corp., an Oregon corporation ("Parent"), and Blue Water Corp., an
indirect subsidiary of Parent ("Sub"). We note that Parent owns a 50% voting
interest in AWT, which, in turn, owns approximately 67% of the outstanding
shares of the common stock, par value $0.01 per share, of the Company (the
"Common Stock"), and the Public Stockholders own approximately 33% of the
outstanding Common Stock.

            The Merger Agreement will provide for, among other things, a merger
of Sub with and into the Company (the "Merger"), which will be the surviving
corporation. In the Merger, each outstanding share of common stock, par value
$1.00 per share, of the Sub will be converted into one share of common stock,
par value $0.01 per share, of the surviving corporation, and each outstanding
share of Common Stock (other than any such shares held in the treasury of the
Company or owned by Parent, Sub or their respective subsidiaries (other than
AWT)) will be converted into 1/39,268,266 of a share of the surviving
corporation (the "Exchange Ratio"), with cash being paid with respect to any
shares of Common Stock that would result in a fractional interest in the
surviving corporation. It is anticipated that all of the Public Stockholders
will receive such cash
<PAGE>   49
Special Committee of the Board of Directors
December   , 2000
Page 2


payment for all of their shares of Common Stock held immediately prior to the
effective time of the Merger at the rate of [$_______] per share of Common
Stock. We note that as a result of the Exchange Ratio, AWT will obtain two whole
shares of the surviving corporation. The Merger Agreement also provides that a
condition to the consummation of the Merger is that a majority of the shares of
the Common Stock cast either for or against the adoption of the Merger Agreement
(excluding shares of Common Stock owned by Parent, Sub, AWT or their respective
subsidiaries) must be cast for the adoption of the Merger Agreement. The terms
and conditions of the Merger are set forth in more detail in the Merger
Agreement.

            In connection with rendering our opinion, we have reviewed the
Merger Agreement and the Support Agreement, each dated as of December ___, 2000,
by and between the Company and AWT. We have also reviewed and analyzed certain
publicly available business and financial information relating to the Company
for recent years and interim periods to date, as well as certain internal
financial and operating information, including financial forecasts, analyses and
projections prepared by or on behalf of the Company and provided to us for
purposes of our analysis, and we have met with management of the Company and
certain of its subsidiaries to review and discuss such information and, among
other matters, each of the Company's and its subsidiaries' business, operations,
assets, financial condition, including its liquidity and capital needs, and
future prospects, as well as the regulatory climate in which the Company's
subsidiaries operate.

            We have reviewed and considered certain financial and stock market
data relating to the Company, and we have compared that data with similar data
for certain other companies, the securities of which are publicly traded, that
we believe may be relevant or comparable in certain respects to the Company or
one or more of its businesses or assets, and we have reviewed and considered the
financial terms of certain recent acquisitions and business combination
transactions in the water utility industry specifically that we believe to be
reasonably comparable to the Merger or otherwise relevant to our inquiry. We
have also performed such other financial studies, analyses, and investigations
and reviewed such other information as we considered appropriate for purposes of
this opinion.

            In our review and analysis and in formulating our opinion, we have
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided to or discussed with us or publicly available,
and we have not assumed any responsibility for independent verification of any
of such information. We have also assumed and relied upon the reasonableness and
accuracy of the financial projections, forecasts and analyses provided to us,
and we have assumed that such projections, forecasts and analyses were
reasonably prepared in good faith and on bases reflecting the best currently
available judgments and estimates of the Company's management. We express no
opinion with respect to such projections, forecasts and analyses or the
assumptions upon which they are based. In addition, we have not reviewed any of
the books and records of the Company, or assumed any responsibility for
<PAGE>   50
Special Committee of the Board of Directors

Page 3


conducting a physical inspection of the properties or facilities of the Company,
or for making or obtaining an independent valuation or appraisal of the assets
or liabilities of the Company. We have assumed that the transactions described
in the Merger Agreement will be consummated without waiver or modification of
any of the material terms or conditions contained therein by any party thereto.
Our opinion is necessarily based on economic and market conditions and other
circumstances as they exist and can be evaluated by us as of the date hereof.

            It should be noted that in the context of our engagement by the
Special Committee, we were not authorized to, and did not solicit, third party
indications of interest in acquiring all or any part of the Company and we were
not authorized to investigate any alternative transactions that may be available
to the Company. You have advised us, and we have relied on your advice, that J.
Henry Schroder and Co., a predecessor to Salomon Smith Barney Inc., and Merrill
Lynch, Pierce, Fenner & Smith Incorporated, advisors to the Company, solicited
indications of interest from potential acquirors of, or merger partners for, the
Company, as well as responded to certain other potentially interested parties
for the Company or certain of its significant assets.

            In the ordinary course of our business, we may actively trade the
debt and equity securities of the Company and Parent for our own account and for
the accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.

            We are acting as financial advisor to the Special Committee in
connection with the proposed Merger and will receive a fee for our services,
(including rendering this opinion), a significant portion of which is contingent
upon the consummation of the Merger. We previously advised the Special Committee
of an engagement in 1996 to provide financial advice to an affiliate of Enron
with respect to a possible acquisition of another corporation and we received
fees for those services.

            Our opinion addresses only the fairness from a financial point of
view to the Public Stockholders of the Merger Consideration provided for
pursuant to the Merger Agreement, and we do not express any views on any other
term of the Merger. Specifically, our opinion does not address the Company's
underlying business decision to effect the transactions contemplated by the
Merger Agreement. In addition, our opinion does not address the solvency of the
Company following consummation of the Merger or at any time.

            It is understood that this letter is for the benefit and use of the
Special Committee in its consideration of the Merger and, except for inclusion
in its entirety in the Schedule 13E-3 statement or proxy statement required to
be circulated to stockholders of the Company relating to the Merger, may not be
quoted, referred to or reproduced at any time or in any manner without our prior
written consent. This opinion does not constitute a recommendation to any
stockholder or as to how such holder should vote with respect to the Merger, and
should not be relied upon by any stockholder as such.

                                Very truly yours,

Note: Valuation from 12/31/00 to 12/31/2023

(1)  By contract, the concession is entitled to receive its net book value at
     the end of 2023. Therefore, terminal value consists solely of net book
     value in 2023 discounted to the present

(2)  Azurix loaned $20 million to the Cancun concession. Therefore, the
     $20 million loan has been added back in order to estimate the total
     enterprise value to Azurix
