     This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully, including our financial data
and related notes, before making an investment decision. Unless we indicate

100,000-for-1 common stock split effective February 2, 1999.
    
 
   
                                  AZURIX CORP.
    
 
   
     Azurix Corp. is a global water company engaged in the business of
acquiring, owning, operating and managing water and wastewater assets, providing
water and wastewater related services and developing and managing water
resources. Enron Corp., one of the world's leading integrated natural gas and
electricity companies, formed Azurix to pursue opportunities in the global water
industry. Azurix's first significant step was to acquire Wessex, a water and
wastewater company based in southwestern England, for $2.4 billion on October 2,
1998. Wessex was recognized in December 1998 by the Office of Water Services,
the industry regulator for England and Wales, as the most efficiently operated
water and wastewater company in the region.
    
 
   
     Our asset portfolio also includes interests in long-term water concessions
in the Province of Mendoza, Argentina and in Cancun, Mexico. In addition, on
March 25, 1999, we agreed to purchase all of the stock of Philip Utilities
Management Corporation, a water and wastewater services company in the United
States and Canada, for $107 million. The acquisition is expected to close in the
second quarter of 1999. Upon completion of the acquisition, we will provide
operations and management, engineering, residuals management and underground
infrastructure development services for municipal water and wastewater
facilities in North America. We have made each of these investments through one
or more subsidiaries, which will be our approach as we pursue our worldwide
growth strategy.
    
 
   
     On a pro forma basis, assuming the Wessex acquisition occurred on January
1, 1998, and including Mendoza from the date of our investment but excluding
Cancun and Philip Utilities, we had operating revenues of $464.2 million, EBITDA
of $298.1 million and net income of $87.2 million for the year ended December
31, 1998 and total assets of $3,358.3 million as of December 31, 1998. To date,
all of our operating revenues have come from Wessex, and substantially all of
our operations have been conducted by Wessex.
    
 
   
     We are aggressively pursuing additional water and wastewater transactions
in Europe, North America, Latin America, the Middle East, Africa, Asia and the
Pacific Rim. These include many of the upcoming privatizations identified in
this prospectus as well as various privately negotiated transactions.
    
 
   
     Our experienced management team from Enron, Wessex and other water and
wastewater systems, and multinational companies provides us with the experience
necessary to compete successfully in the global water industry. We are
transferring the skills that Enron has successfully applied in developing,
financing, operating and managing the risks of energy infrastructure projects to
our water business around the world. In addition, we are applying to our water
business the operating, management and technical skills that our executives from
Wessex and other companies have successfully used in operating and managing
water and wastewater assets while providing high quality customer service. This
management team competitively positions us to identify, evaluate, acquire,
develop, finance and operate water and wastewater projects and services
worldwide.

                           THE GLOBAL WATER INDUSTRY
    
 
   
     The global water industry includes the collection, treatment, storage and
supply of drinking water, and the collection, treatment and disposal of
wastewater and its by-products. Public (municipal and other governmental) and
private (non-governmental) water companies serve industrial, commercial and
residential customers. Azurix estimates that the global water industry has total
annual revenues of approximately $300 billion. In addition, Azurix estimates
that over $600 billion will be spent on worldwide water and wastewater
infrastructure over the next decade.
    
 
   
     We believe that significant business opportunities exist for private sector
participation in the global water industry. These opportunities include taking
part in water and wastewater privatizations, providing water and wastewater
related services to municipal and industrial water markets and developing and
managing water resources. Some of the factors creating these business
opportunities for private sector participation in the global water industry
include:
    
 
     - Governments and industrial companies are recognizing that transferring
       ownership, operation or management of water and wastewater assets to
       experienced private parties, called outsourcing, is often more efficient
       and cost-effective than owning or operating these assets themselves.
 
   
     - Major capital investment and efficiency improvements are necessary to
       meet higher standards of water and wastewater quality and environmental
       protection, to connect growing populations to water and wastewater
       systems and to replace aging water and wastewater infrastructure.
    
 
   
     - Ownership of water and wastewater assets is highly concentrated in the
       public sector, and governments frequently face budgetary constraints and
       often lack the technical expertise to address these issues effectively.
    
 
   
     - Increasing demand for water resources is focusing efforts on water
       resource development and management, the means of extracting, managing,
       storing and transporting water resources as efficiently as possible, and
       of managing the risks related to these activities.
    
 
   
     Significant barriers to entry limit the number of companies capable of
competing globally in the markets for water and wastewater privatization,
municipal and industrial outsourcing of services and resource development and
management. Participants must have the requisite operating experience and
management depth to qualify for bidding on international privatizations or
concessions, as well as an ability to identify and evaluate transactions, access
adequate capital at cost-effective levels and develop and manage international
infrastructure projects.
    
 
                           OUR COMPETITIVE STRENGTHS
 
   
     We have several competitive strengths that should enable us to compete
successfully in the global water industry:
    
 
   
     - EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAMS. Although our
       company was only recently formed, we have a group of experienced managers
       from long-established companies, including Enron, other multinational
       companies, Wessex and other water and wastewater companies. Our
       management team has extensive experience in both the development and
       operation of infrastructure projects worldwide and years of experience in
       managing water and wastewater companies primarily in the United Kingdom
       and also in the United States. Our senior executives are complemented by
       a group of experienced business developers who identify opportunities in
       the global water industry. We believe that the collective experience of
       our management and business development teams will enable us to compete
       successfully for public tenders. Since our formation, we have qualified
       for bidding on numerous pending privatizations in Europe, Latin America
       and the Middle East. Of those privatizations in which we have actively
       participated, only one award has been made. In this bid for the
       concession in Valparaiso, Chile, we were second to the winning bidder. We
       are currently one of the three finalists for the partial privatization of
       the Berlin,
    
 
                                        2
<PAGE>   8
 
   
       Germany water and wastewater system. In addition, we have identified and
       negotiated successfully two private transactions.
    
 
     - WESSEX OPERATING EXPERIENCE AND TECHNICAL EXPERTISE. From Wessex, we have
       obtained the operating experience, research skills and technical
       expertise necessary to evaluate potential water projects, to qualify for
       bidding on water projects in many countries throughout the world, to
       build transition and operating teams for new acquisitions and to manage
       existing and new water assets. We intend to transfer to our global water
       business the operating efficiency, advanced technology, capital
       expenditure and operational cost management and regulatory management
       skills used successfully by Wessex in operating and managing its water
       and wastewater assets.
 
     - REGULATORY AND GOVERNMENT AFFAIRS EXPERTISE. Our management team has
       extensive experience in working with regulators and other governmental
       agencies and has knowledge of the regulatory framework and privatization
       processes in many of the countries in which we intend to pursue water and
       wastewater opportunities. This experience and knowledge will allow us to
       assess more successfully the regulatory risk and opportunity presented by
       those projects we evaluate.
 
     - FINANCING EXPERTISE. Members of our management team have experience using
       sophisticated financing and capital raising techniques, in both global
       and local markets, to lower the cost of capital for the financing of
       projects and acquisitions. As our portfolio grows and matures, we intend
       to enhance our equity returns and reduce overall risk exposure through
       opportunistic sales of all or a portion of individual assets or
       investments that have appreciated in value.
 
                             OUR BUSINESS STRATEGY
 
     Our business strategy is focused on three complementary areas in the global
water industry:
 
   
     - ACQUIRING, OWNING, OPERATING AND MANAGING WATER AND WASTEWATER ASSETS. We
       intend to build a diversified portfolio of water and wastewater assets,
       including both established businesses with stable returns and concessions
       and projects in emerging markets with significant development
       requirements and potential for growth and enhanced returns. We intend to
       acquire water and wastewater assets through participation in public
       tenders and privately negotiated transactions throughout the world,
       including Europe, North America, Latin America, the Middle East, Africa,
       Asia and the Pacific Rim. Following an acquisition of water or wastewater
       assets, we plan to increase revenues by expanding customer bases and
       improving the accuracy and timing of billing and collection procedures.
       In addition, we intend to grow operating income by improving quality,
       extending services, reducing operating costs, prioritizing and managing
       capital expenditures, increasing efficiency and applying, where
       appropriate, sophisticated financing techniques.
    
 
   
     - PROVIDING WATER AND WASTEWATER RELATED SERVICES. Through innovative
       technological, environmental and financial solutions, we intend to
       provide a broad range of services to municipal and industrial owners of
       water and wastewater systems around the world. These services will
       include: 
    

   
      -- Operations, management and engineering -- services to design, build, 
         operate or maintain water and wastewater assets
    

   
      -- Residuals management -- services to dispose of wastewater and biosolids
         that result from wastewater treatment
    
 
   
      -- Underground infrastructure remediation and development -- services to
         repair and replace water and wastewater distribution and collection
         systems
    
 
   
     - DEVELOPING AND MANAGING WATER RESOURCES. We intend to pursue
       opportunities in water resource development and management and address
       the capital, technical and operational needs in this area of the water
       industry.

     By pursuing our business strategy in these three areas, we plan to offer a
full spectrum of services to meet our public and private customers' water and
wastewater needs. In evaluating potential investments, we plan to follow a
disciplined approach focused on identifying the potential for increased returns,
analyzing the impact on tariffs and revenues of the future regulatory regime and
assessing the engineering, operational, regulatory, financing, economic,
structuring, insurance, tax, environmental, legal and accounting risks related
to each transaction. We believe this approach will allow us to identify and
compete successfully for those water and wastewater projects offering attractive
rates of return.
    
 
     Our principal executive offices are located at 333 Clay Street, Houston,
Texas 77002 (telephone number (713) 646-6001) and 34 Park Street, London W1Y
3PF, England (telephone number (44) 171-970-7763).

                          AZURIX'S CORPORATE STRUCTURE
    
 
   
     The following chart illustrates our corporate structure, after the
offering, including our stockholders, significant subsidiary and other
investments. This chart does not show our complete corporate structure and
should be read in conjunction with the more detailed descriptions contained
elsewhere in this prospectus.

              ATLANTIC WATER TRUST'S OWNERSHIP INTEREST IN AZURIX
    
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately   % of our outstanding common stock,   % if the underwriters'
over-allotment options are exercised in full. Each of Enron and Marlin Water
Trust, a Delaware business trust, owns a 50% voting interest in Atlantic Water
Trust. To date, Enron has appointed all of the directors of Atlantic Water Trust
and Azurix, although Marlin Water Trust at any time has the right to elect or
replace half of the directors of Atlantic Water Trust and currently up to half
of the Azurix directors. Following the offering, as long as Atlantic Water Trust
owns a majority of our outstanding common stock, Marlin Water Trust has the
right to direct Atlantic Water Trust to elect or replace a percentage of
Azurix's directors equal to 50% minus the percentage of outstanding common stock
held by persons other than Atlantic Water Trust. Furthermore, Marlin Water
Trust, with the consent of the holders of a majority of our outstanding common
stock held by persons other than Atlantic Water Trust, Enron and its affiliates,
has the right to direct Atlantic Water Trust to elect or replace half of
Azurix's directors. Enron has the right to direct Atlantic Water Trust to elect
or replace the other half of Azurix's directors. As a result, following the
offering, Enron and Marlin Water Trust will continue to exert significant
influence over the policies, management and affairs of Azurix and the outcome of
most corporate actions requiring stockholder approval, including the approval of
transactions involving a change in control of Azurix. See "Certain
Transactions," "Principal and Selling Stockholders" and "Shares Eligible For
Future Sale."
    
 
   
                     RELATIONSHIP BETWEEN AZURIX AND ENRON
    
 
   
     We intend to enter into agreements with Enron, including a business
opportunities agreement, a services agreement, a credit agreement and a license
agreement. The business opportunities agreement will limit the scope of our
business to the businesses generally identified in this prospectus and
activities incidental to those businesses. The agreement will also provide that
Enron and its affiliates may engage in water-related businesses, even if those
activities have a competitive impact on Azurix. Under the services agreement,
Enron will provide various corporate staff and support services to us. Under the
credit agreement, Enron will provide funds to us for general, administrative and
operating expenditures. See "Certain Transactions" for a more detailed
discussion of these agreements.

     SUMMARY HISTORICAL AND UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA
 
     The following tables present summary historical and unaudited pro forma
consolidated financial data for Azurix and for Wessex, the predecessor of
Azurix, for the periods and dates indicated. The unaudited pro forma financial
data for Azurix are derived from the unaudited condensed consolidated pro forma
financial data included elsewhere in this prospectus. The unaudited pro forma
financial data give effect to the acquisition of Wessex, the redemption and
elimination of Wessex's preference shares for an aggregate price of $249.8
million and the sale by Wessex of its interest in UK Waste for $337.9 million,
as though each occurred on January 1, 1998. The unaudited pro forma financial
data presented below is not necessarily indicative of the financial results that
would have occurred had the acquisition of Wessex, the redemption and
elimination of Wessex's preference shares and the sale by Wessex of its interest
in UK Waste occurred on January 1, 1998 and should not be viewed as indicative
of operations in future periods. See "Selected Historical and Unaudited Pro
Forma Consolidated Financial Data" for more information regarding the
historical, the unaudited pro forma consolidated and the other financial data.

(1) The year ended March 31, 1998 includes a windfall tax of $162.3 million,
    which has been described by the U.K. government as a one-time tax. Excluding
    the effect of this tax, for the year ended March 31, 1998, Wessex's net
    income would have been $179.0 million.

    a comparative basis to Azurix and, therefore, are not presented.
 
   
(3) EBITDA for any relevant period presented above is defined as net income
    before net interest (income) expense, income tax, utility tax, depreciation
    and amortization. EBITDA is not a measure recognized by generally accepted

                                  RISK FACTORS
 
     Investing in the common stock will provide you with an equity ownership
interest in Azurix. As an Azurix stockholder, you will be subject to risks
inherent in our business. The performance of your shares will reflect the
performance of our business relative to, among other things, competition, market
conditions and general economic and industry conditions. The value of your
investment may increase or decline and could result in a loss. You should
carefully consider the following factors as well as other information contained
in this prospectus before deciding to invest in shares of the common stock.
 
   
BECAUSE WE HAVE A LIMITED OPERATING HISTORY, OUR FUTURE OPERATING RESULTS ARE
DIFFICULT TO FORECAST.
    
 
   
     We are a new company with a limited operating history. Our limited
operating history and the unpredictable results of our acquisition strategy make
it difficult to forecast our future operating results. The financial data
presented in this prospectus may not be indicative of our future financial or
operating results. We expect to experience significant competition in bidding
and negotiating for water projects worldwide. As a new company, we will face
competition from companies that have a longer operating history and have more
experience in bidding for water and wastewater projects. Our limited operating
history may create impediments to our being successful in bidding. For example,
we may be at a disadvantage in bidding for some projects because we may not have
a history of operating in a country or region, or we may not have a history of
operating a water or wastewater system or individual treatment plant of a size
comparable to the system or facility being privatized or built.
    
 
   
     We will derive our consolidated operating revenues almost exclusively from
the operations of Wessex until such time as our other investments begin to
generate revenue. Operating revenues from Wessex may not be available for
distribution to Azurix due to operating and financing requirements of Wessex,
financing requirements of intermediate companies, regulatory developments
affecting the rates Wessex may charge its customers and other regulatory or
other restrictions on its ability to pay dividends to its shareholders.
    
 
   
OUR PROFITABILITY AND PROSPECTS FOR GROWTH ARE HIGHLY DEPENDENT ON COMPLETING
ACQUISITIONS AND DEVELOPING PROJECTS.
    
 
   
     There is a risk that we may not be able to successfully complete
acquisitions of water and wastewater assets and develop projects because these
transactions involve many complexities. Such complexities include, among other
things, negotiation of satisfactory water supply and wastewater treatment
services agreements with local governments and receipt of required governmental
consents and permits. In addition, in evaluating and negotiating water projects,
water companies typically encounter difficulties in determining the status and
condition of existing systems or developing accurate forecasts of material
factors such as the rate of population growth, particularly in developing
countries. In privatization transactions, we may be unable to predict with
certainty the timing of a privatization or the commitment level of a government
to completing a privatization. In addition, most privatizations are
competitively bid, and there is no assurance as to what proportion of the
projects on which we bid will be acquired by us. Because part of our business
strategy is to grow through acquisitions and development projects, we have
recently put in place a business development effort with associated general,
administrative and operating expenses. To the extent we are not successful in
completing acquisitions and development projects, these expenses will not be
absorbed by revenues associated with those acquisitions and development projects
and will decrease our net income. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Outlook."
    
 
   
WATER AND WASTEWATER COMPANIES FACE PRICE REGULATION THAT COULD REDUCE OUR
OPERATING REVENUES.
    
 
   
     Governments generally regulate the prices that water and wastewater
companies may charge their customers. Regulatory regimes vary from country to
country and at times can give great discretion to the regulatory authority.
Moreover, the regulatory authorities in countries where we currently operate, or
may operate in the future, could change without notice, as could the regulations
they promulgate. These changes could cause reductions in our operating revenues.
In the case of Wessex, the U.K. Director
    
 
                                        8
<PAGE>   14
 
   
General of Water Services is currently conducting a periodic review of the price
limits for water and wastewater companies in England and Wales that is expected
to result in new price limits for the period from April 1, 2000 through 2005. In
setting prices, the Director must ensure that water companies are able to
finance the proper carrying out of their functions, in particular, by securing a
reasonable return on their capital.
    
 
   
     In October 1998, the Director proposed an initial price cut for Wessex in
excess of 17.5% from 1999-2000 to 2000-2001, with prices gradually increasing
thereafter but remaining below the 1999-2000 levels in 2004-2005. Following this
proposal, the U.K. Government announced its decision to require greater capital
expenditures for water and wastewater companies for environmental improvements.
Subsequently, in its April 1999 business plan filed with the Director, Wessex
proposed stable prices from 1999-2000 to 2000-2001, with prices gradually
increasing to 18% higher than current levels in 2005, primarily to fund capital
expenditures mandated by the new environmental standards. The Director has
stated that he will publish draft price limits in July 1999 with the final
determination being made in November 1999. Although we are unable to predict the
precise outcome of the current U.K. rate review, if Wessex were required to cut
its prices as originally proposed by the Director, Wessex's operating revenues
would be reduced by approximately 17.5% and its earnings would be reduced
materially.
    
 
   
FAILURE TO IDENTIFY AND ASSESS ACCURATELY THE RISKS RELATED TO AN ACQUISITION OR
PROJECT COULD REDUCE OUR OPERATING RESULTS, INCLUDING EARNINGS.
    
 
   
     In evaluating potential transactions, we make assumptions and projections
based on the potential for increased returns, future regulatory and rate case
changes and the engineering, operations, financing, economic structuring,
insurance, tax, environmental, legal and accounting risks relating to each
transaction. Forecasts, estimates and information provided by local governments
and other sources used to bid for public tenders can prove to be materially
inaccurate or incomplete, resulting in projections for capital expenditures to
improve or build water systems that are below what is ultimately required. If
the assumptions on which we base our decision to acquire assets or develop a
project prove to be incorrect in any material respect, either because of
inaccurate or incomplete information provided by the other party or parties to
the transaction or because of a failure by us to accurately identify or assess
the risks or capital requirements related to a proposed acquisition or project,
then our operating results, including earnings, could be materially adversely
affected. While we attempt to identify all risks associated with any given
transaction, no assurance can be given that we will identify all risks related
to a transaction.
    
 
   
BECAUSE OUR BUSINESS REQUIRES SUBSTANTIAL CAPITAL EXPENDITURES, DIFFICULTY
FINANCING OUR OPERATIONS, ACQUISITIONS AND PROJECTS COULD LIMIT OUR GROWTH AND
REDUCE OUR EARNINGS.
    
 
   
     The water assets and projects in which we plan to invest may require
substantial capital expenditures, especially early in the life of our
investments. We intend to finance our investments and projects using various
techniques and instruments such as debt financing, project financing and equity
investments. There is a risk that we may engage in leveraged transactions and
that we may pledge all or substantially all of our assets. For example, the
capital stock of Wessex is pledged as security for the senior credit facility of
Azurix Europe Ltd, Wessex's holding company. In addition, there is a risk that
financing may not be readily available to acquire water and wastewater assets or
develop projects. Our ability to arrange financing will be affected by general
economic and capital market conditions, credit availability from banks or other
lenders and the risks inherent in particular concessions, projects or countries.
In particular projects, we may have a co-owner with limited resources or that
may default on its obligations to contribute capital to the project. Enron is
not obligated to provide additional financial support to Azurix for any capital
expenditures or investments.
    
 
   
IF WE DO NOT HAVE OPERATIONAL CONTROL IN A PROJECT, OUR OPERATING REVENUES AND
EARNINGS COULD BE REDUCED.
    
 
     We may invest in water and wastewater projects and assets in which we do
not own a majority of the project or assets. In addition, we may invest in or
own projects and assets with partners, co-venturers and other parties, including
governmental entities. Some jurisdictions require participation of employees or
                                        9
<PAGE>   15
 
   
other stakeholders in company management. In these cases, major decisions may
require the consent of other equity owners or stakeholders.
    
 
   
     We may also invest in projects and assets where we do not serve as
operator. For example, we do not have operational control in our Mendoza,
Argentina concession. In these cases, our ability to direct the outcome of
matters with respect to the operations of the project or assets could be
limited. A lack of operational control in a project could materially and
adversely affect our interest in the project and, as a result, our operating
revenues and earnings from the project.
    
 
   
SUCCESS OF OUR BUSINESS STRATEGY MAY BE LIMITED BY OUR ABILITY TO INTEGRATE
ACQUISITIONS AND MANAGE OUR GROWTH SUCCESSFULLY.
    
 
   
     We intend to grow in part through acquisitions of water and wastewater
assets. Because we are pursuing acquisitions around the world and because we are
actively pursuing a number of opportunities simultaneously, we may encounter
unforeseen expenses, difficulties, complications and delays, including
difficulties in staffing and providing operational and management oversight. As
we expand our operations through acquisitions, we may encounter difficulties
integrating such acquisitions and successfully managing the growth of a
portfolio of water and wastewater assets that is diverse both with respect to
types of assets and their location. We cannot assure you that our current
management, personnel and other corporate infrastructure will be adequate to
manage our growth or that our systems, procedures and controls will be adequate
to support our expanding operations. To the extent we encounter problems in
integrating acquisitions and managing our growth, our financial results and the
market price of our common stock could be materially adversely affected.
    
 
   
ENVIRONMENTAL FACTORS AND CHANGES IN REGULATIONS COULD INCREASE OUR COSTS OR OUR
LIABILITIES.
    
 
     There is a risk that changes in regulations applying to the water supply or
wastewater treatment services industry or new, revised or inconsistent
interpretations of these regulations may adversely affect our financial
condition and results of operations. Water companies are subject to water
quality risks related to contamination of drinking water supplies or
environmental danger from effluent discharges. The occurrence of these or other
risks could have a material adverse effect on our financial position and results
of operations.
 
   
     In addition, many countries in which we plan to do business have recently
developed, or are in the process of developing, new regulatory and legal
structures that regulate the delivery of drinking water and wastewater services
and accommodate private and foreign-owned water businesses. In some instances,
these regulatory and legal structures and their interpretation and application
by administrative agencies are relatively new and incomplete. The interpretation
of existing rules can be expected to evolve over time and may have an
unpredictable impact on our business. We anticipate future changes in, or
decisions affecting, regulatory regimes that will serve to expand or tighten
regulatory controls. Some of these changes or decisions could have a material
adverse effect on our financial position and results of operations.
    
 
     We may handle hazardous substances in our industrial services business in
addition to biological waste. Stringent environmental laws provide for serious
penalties and sometimes impose strict liability on those who handle these
substances or find them on their property. Accordingly, if we handle hazardous
substances in our industrial services business in the future, there is a risk
that we will incur liabilities and expenses related to the handling of hazardous
substances. Although we maintain insurance against many of these risks, we
cannot be certain that insurance proceeds received under our policies would
adequately cover all liabilities we might incur.
 
   
LIABILITY FOR WATER SUPPLY CONTAMINATION COULD RESULT IN MATERIAL LOSSES AND
COSTS.
    
 
     Where we supply water to end-users, our business is subject to risks of
contamination of the water supply, which could result in disease or even death
or otherwise endanger the public health. As a result of contamination, we could
be subject to civil or criminal enforcement actions, private suits and cleanup
obligations, which could have a material adverse effect on our financial
condition and results of operations.
                                       10
<PAGE>   16
 
Drinking water contamination can be caused by, among other things, wastewater
effluent, stormwater runoff from farms and industrial sites, materials used in
the construction or rehabilitation of water supply pipes, harmful nitrates
attributable to modern farming practices and various other pathogens from a
variety of sources entering the drinking water supply. Accordingly, there can be
no assurance that our water supply will not become contaminated. Although we
maintain insurance against many of these risks, we cannot be certain that
insurance proceeds received under our policies would adequately cover all
liabilities we might incur.
 
   
POLITICAL AND ECONOMIC CHANGES IN COUNTRIES IN WHICH WE OPERATE COULD ADVERSELY
AFFECT OUR OPERATING RESULTS.
    
 
     The success of our strategy in many countries will depend on a political
and economic environment that will accommodate foreign investment and project
development. Our operations will be subject to political and economic risks,
including risks of war, terrorism, expropriation, nationalization, renegotiation
or nullification of existing contracts, changes in rates and methods of taxation
and foreign exchange controls or governmental restrictions on the repatriation
of hard currency. You should be aware that we will operate in countries whose
economies differ in many respects from the economies of the United States,
Canada and most Western European countries, including their structure, levels of
capital reinvestment, growth rate, government involvement, resource allocation,
self-sufficiency, rate of inflation and balance of payments position. In many of
these countries, the government retains significant control over the economy.
Thus, there is a risk that future government actions, especially with respect to
nationally important facilities such as water systems, could have a material
adverse effect on our financial condition and results of operations.
 
   
WORK STOPPAGES AND OTHER LABOR RELATIONS MATTERS COULD ADVERSELY AFFECT OUR
OPERATING RESULTS.
    
 
   
     We are subject to a risk of work stoppages and other labor relations
matters because we have invested and will invest in the future in assets and
projects utilizing a workforce that in many cases will be unionized. For
example, a portion of the work forces at Wessex, Mendoza, Cancun and Philip
Utilities are represented by unions. In addition, our ability to obtain an
adequate return on an investment will often depend on our success in optimizing
the labor force through voluntary and sometimes involuntary staff reductions.
There is a risk that layoffs, where implemented, could trigger community or
union problems. We cannot assure you that issues with our labor forces will be
resolved favorably to us in the future or that we will not experience work
stoppages in future years.
    
 
   
CHANGES IN CURRENCY EXCHANGE RATES, LIMITATIONS ON SENDING FUNDS OUT OF A
FOREIGN COUNTRY AND FOREIGN CURRENCY RESTRICTIONS OR SHORTAGES COULD ADVERSELY
AFFECT OUR OPERATING RESULTS.
    
 
   
     Because we conduct operations outside the United States, limitations on the
right to convert currency or to take it out of a foreign country, changes in
exchange rates and the capacity of currency exchange markets may adversely
affect our ability to repatriate profits. As of December 31, 1998, 98.5% of our
total liabilities were non-U.S. dollar denominated. For the year ended December
31, 1998, 100% of our operating revenues were non-U.S. dollar denominated but
were in the same currency as our non-U.S. dollar denominated liabilities. Legal
restrictions or shortages in currencies in countries outside the United States
may prevent us from converting sufficient local currency to enable us to comply
with our currency payment obligations not denominated in local currency or to
meet our operating needs and debt service requirements.
    
 
   
OPERATING IN COUNTRIES WITHOUT ADEQUATE REVENUE COLLECTION SYSTEMS COULD REDUCE
OUR OPERATING REVENUES.
    
 
     There is a risk that we will operate in countries whose legal systems do
not have established or well-enforced collection mechanisms for their water
supply and wastewater treatment services. Also, customers in such countries may
not be able or willing to pay for water services. This could have a material
adverse effect on our financial condition and results of operations. There can
be no assurance that government subsidies or taxes and other concessions will
sufficiently compensate private parties that provide these services for the
economic consequences of such conditions. Where initially available, there is a
risk that
                                       11
<PAGE>   17
 
such subsidies and concessions could be reduced or eliminated before reliable
revenue sources and collection mechanisms can be established.
 
   
INTERACTION OF DIFFERENT COUNTRIES' TAX LAWS COULD LOWER OUR RETURNS.
    
 
   
     Tax laws in various countries treat differently the taxability of various
aspects of income and gain and the deductibility of expenses and losses. Income
earned in one jurisdiction also may be taxable in another, including the United
States. Although in many instances U.S. tax laws will permit us to credit
amounts paid in taxes in other countries against our U.S. tax obligations, the
rules allowing credits are complex and do not allow credits in many
circumstances. Moreover, if we incur expenses in one jurisdiction that benefit a
project in another, they may not be deductible against income in the
jurisdiction where the expenses were incurred. This could occur, in particular,
in the United States, if our operating revenues from future U.S. operations do
not exceed the expenses we incur in the United States in supporting our
worldwide operations.
    
 
   
OPERATING IN COUNTRIES WITH UNDEVELOPED LEGAL SYSTEMS COULD ADVERSELY AFFECT OUR
BUSINESS BECAUSE WE MAY ENCOUNTER DIFFICULTIES ENFORCING OUR CONTRACTUAL RIGHTS.
    
 
   
     Developing countries in which we may pursue opportunities may not have
well-established legal systems and lack a well-developed, consolidated body of
laws governing foreign investment enterprises. The uncertainty of the legal
environment in these countries could make it difficult for us to enforce our
rights, or those of our operating companies, under agreements relating to our
operations. In addition, the administration of laws and regulations by
government agencies in such countries may be subject to considerable discretion
or prejudice against foreigners or private investors. As these legal systems
develop, foreign investors may be adversely affected by new laws and changes to
existing laws. In addition, in countries where adequate laws and well-developed
legal systems do exist, it may not be possible to obtain swift and equitable
enforcement of such laws.
    
 
   
RESTRICTIONS IN DEBT AGREEMENTS COULD LIMIT OUR GROWTH AND OUR ABILITY TO
RESPOND TO CHANGING CONDITIONS.
    
 
   
     We conduct substantially all of our operations through subsidiaries, and
substantially all of our assets consist of equity in our subsidiaries. Some of
the debt financing arrangements to which our subsidiaries are a party impose
restrictions on their business operations, which may affect our business
operations. The covenants contained in the credit agreements to which Azurix
Europe and Wessex are parties will have several restrictive effects on our
future operations. For example, the covenants contained in the existing senior
credit facility and the new senior credit facility for Azurix Europe require
Wessex to meet financial tests and limit Wessex's ability to borrow additional
funds or dispose of assets. These covenants could hinder our flexibility in
planning for, and reacting to, changes in our business. In addition, our ability
to obtain additional financing for working capital, capital expenditures,
acquisitions, general corporate and other purposes at the Azurix level may be
limited by the fact that the capital stock of Wessex is pledged as security for
Azurix Europe's existing senior credit facility and new senior credit facility.
Additionally, covenants contained in the new senior credit facility restrict
Azurix Europe from paying dividends to Azurix. This could limit our ability to
pay dividends on our common stock. See "Description of Indebtedness."
    
 
   
FAILURE OF COMPUTER SYSTEMS TO RECOGNIZE YEAR 2000 COULD HAVE AN ADVERSE EFFECT
ON OUR BUSINESS.
    
 
   
     Year 2000 problems could result from computer hardware and software using
two digits rather than four digits to define the applicable year. These problems
include operational inefficiencies, systems failures, business disruptions and
lost revenues attributable to the inability of these two digit systems to
recognize the Year 2000. We intend to implement Enron's Year 2000 plan to
identify and remediate our Year 2000 problems. However, because we have not
completed our analysis of our Year 2000 readiness or the Year 2000 readiness of
parties on whom we rely, we cannot ensure that the identification and
remediation of our Year 2000 problems will be successful.
    
 
                                       12
<PAGE>   18
 
   
     If our mission-critical information systems fail or if suppliers on which
we depend for essential goods and services experience mission-critical
information system failures, our business could be materially adversely
affected. We could face substantial claims by governments, governmental
authorities or customers, as well as loss of operating revenues, due to service
interruptions, violations of environmental regulations, inability to fulfill
contractual obligations, inability to account for obligations and increased
expenses associated with litigation, harm to persons or to property,
stabilization of operations following system failures and the execution of
contingency plans. In addition, we could face claims of damage to persons or
property as the result of improperly treated water or wastewater.
    
 
     Our preliminary assessment of our Year 2000 issues has not demonstrated a
need to incur material Year 2000 costs. However, the following factors could
result in actual Year 2000 costs being higher than anticipated:
 
     - We intend to engage in future acquisitions and could acquire a business
       with significant Year 2000 problems.
 
     - We depend on third parties, including customers, suppliers and service
       providers, who may fail to address adequately their Year 2000 problems.
 
     - We rely on automated plant systems, computerized billing procedures and
       other embedded chip technologies that could necessitate expensive
       corrective actions.
 
     For a more detailed discussion of the state of our Year 2000 readiness, the
costs we anticipate incurring to become Year 2000 ready and our Year 2000
contingency plans, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Year 2000."
 
   
OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT, THE LOSS OF WHOM COULD
DISRUPT OUR BUSINESS OPERATIONS.
    
 
   
     We depend on the continued employment of key management personnel we have
brought in from Enron, Wessex and other multinational companies. We have entered
into employment agreements with these executives. If these officers resign or
become unable to continue in their present role and if they are not adequately
replaced, our business operations could be materially adversely affected. See
"Management."
    
 
   
BECAUSE WE RELY ON ENRON FOR CORPORATE STAFF AND SUPPORT SERVICES AND UTILIZE
ENRON'S REGULATORY AFFAIRS, MARKETING AFFAIRS, TREASURY AND RISK ASSESSMENT AND
CONTROL DEPARTMENTS, CHANGES IN OUR RELATIONSHIP WITH ENRON COULD INCREASE OUR
COSTS.
    
 
   
     We will have an agreement with Enron pursuant to which Enron will provide
various corporate staff and support services to us. These services include
information technology, building maintenance, security and other office services
as well as employee development, training and maintenance of compensation and
other benefits programs. We also may utilize Enron's regulatory affairs,
marketing affairs, treasury and risk assessment and control departments. In
addition, Azurix may continue to participate in Enron's corporate insurance
program. The agreement will provide that we may use the international offices of
Enron and its affiliates for projects, subject to our mutual agreement with
Enron or its affiliates on a project-by-project basis. Due to prior commitments
that Enron or its affiliates may have in a particular office or due to other
reasons, there is a risk that Enron or its affiliates may not permit Azurix to
use a particular international office for a particular project.
    
 
   
     Our agreement with Enron is for an indefinite term, but either of us may
terminate the agreement on 180 days' notice. We expect that, were Enron to
terminate, during this 180-day period we would be able to arrange alternate
suppliers for all the important services provided. We would expect that these
services would be available from third parties at costs similar to those we pay
Enron. However, where we would have to replicate facilities, services or
employees that we are not using full time, our costs could increase. It is not
possible to predict the specific areas where costs would increase, as that
depends on how much we have grown by the time the agreement terminates.
    
                                       13
<PAGE>   19
 
   
BECAUSE ENRON AND ITS AFFILIATES MAY COMPETE WITH AZURIX IN WATER-RELATED
ACTIVITIES AND BECAUSE AZURIX MAY ONLY ENGAGE IN ACTIVITIES GENERALLY IDENTIFIED
IN THIS PROSPECTUS, INCIDENTAL ACTIVITIES AND OTHER ACTIVITIES AS ATLANTIC WATER
TRUST OR ENRON MAY APPROVE, OUR BUSINESS OPPORTUNITIES COULD BE LIMITED.
    
 
   
     Enron and Azurix will enter into an agreement that limits the scope of
Azurix's business and provides that Enron and its affiliates may engage in
water-related activities, even if those activities have a competitive impact on
Azurix. In general, Enron will be permitted to engage in any business
whatsoever, including water, wastewater and other businesses competing with
Azurix, and may compete in public tenders against Azurix, provided the business
is conducted and opportunities are identified and developed through Enron's own
personnel and not through Azurix. If an opportunity in the water industry is
presented to a person who is an officer or director of both Enron and Azurix,
the opportunity must first be offered to Azurix, unless water constitutes a
minority of the fair market value of the opportunity, as determined by that
officer or director in good faith based on information available at the time.
Azurix will indemnify Enron and its officers, directors and employees against
all claims brought on account of Enron competing with Azurix, provided Enron has
followed the rules just described. Were Enron to decide to pursue activities in
the water or wastewater industry, its size, access to capital and experience in
developing products and markets could make it a strong competitor.
    
 
   
     The agreement will require Azurix to limit its purpose, in its certificate
of incorporation, to the businesses generally identified in this prospectus,
activities incidental to those businesses, and such other businesses as Atlantic
Water Trust may approve in its sole discretion, or if Atlantic Water Trust
ceases to control Azurix, then such other businesses as Enron may approve in its
sole discretion. The agreement thus limits our ability to pursue potentially
profitable activities that are not primarily in the water and wastewater sector,
even though those opportunities come to our attention on account of our
activities in water and wastewater. For example, some jurisdictions may choose
to privatize their water and other utility assets together. As a result of this
agreement, we would need Enron's consent to pursue the privatization if the
water and wastewater aspects were not expected to represent a majority of the
value.
    
 
   
     The agreement will restrict both Enron and Azurix from taking action to
restrict each others' businesses or to subject them to regulation under the U.S.
Public Utility Holding Company Act of 1935. The agreement will expire the first
date on which neither Enron nor Atlantic Water Trust directly or indirectly owns
or has the power to vote at least 35% of the shares of Azurix ordinarily
entitled to vote for the election of directors or otherwise controls Azurix. See
"Certain Transactions -- Agreement Regarding Business Opportunities and Related
Matters."
    
 
   
THROUGH ATLANTIC WATER TRUST, ENRON AND MARLIN WATER TRUST WILL BENEFICIALLY OWN
A MAJORITY OF OUR COMMON STOCK AND WILL BE ABLE TO SIGNIFICANTLY AFFECT THE
OUTCOME OF STOCKHOLDER VOTING.
    
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately      % of our outstanding common stock,      % if the
underwriters' over-allotment options are exercised in full. Each of Enron and
Marlin Water Trust, a Delaware business trust, owns a 50% voting interest in
Atlantic Water Trust. To date, Enron has appointed all of the directors of
Atlantic Water Trust and Azurix, although Marlin Water Trust at any time has the
right to elect or replace half of the directors of Atlantic Water Trust and
currently up to half of the Azurix directors. Following the offering, as long as
Atlantic Water Trust owns a majority of our outstanding common stock, Marlin
Water Trust has the right to direct Atlantic Water Trust to elect or replace a
percentage of Azurix's directors equal to 50% minus the percentage of
outstanding common stock held by persons other than Atlantic Water Trust.
Furthermore, Marlin Water Trust, with the consent of the holders of a majority
of our outstanding common stock held by persons other than Atlantic Water Trust,
Enron and its affiliates, has the right to direct Atlantic Water Trust to elect
or replace half of Azurix's directors. Enron has the right to direct Atlantic
Water Trust to elect or replace the other half of Azurix's directors. As a
result, following the offering, Enron and Marlin Water Trust will continue to
exert significant influence over the policies, management and affairs of Azurix
and the outcome of most corporate actions requiring stockholder approval,
including the approval of transactions involving a change in control of Azurix.
See "Certain Transactions" and "Principal and Selling Stockholders."
    
                                       14
<PAGE>   20
 
   
A MAJORITY OF OUR DIRECTORS MAY HAVE CONFLICTS OF INTEREST BECAUSE THEY ARE ALSO
ENRON DIRECTORS OR OFFICERS.
    
 
   
     Currently, a majority of our directors are also directors or officers of
Enron, a situation that may create conflicts of interest. The directors and
officers of Enron have fiduciary duties to manage Enron, including its
investments in subsidiaries and affiliates such as Azurix, in a manner
beneficial to Enron and its stockholders. Similarly, the directors and officers
of Azurix have fiduciary duties to manage Azurix in a manner beneficial to
Azurix and its stockholders. In some circumstances, the duties of these
directors and officers of Enron may conflict with their duties as directors of
Azurix. In addition, other conflicts of interest exist and may arise in the
future as a result of the extensive relationships between Enron and Azurix.
Enron and Azurix have agreed that conflicts of interest between Enron and Azurix
may be resolved through approval by a majority of the directors of Azurix not
associated with Enron. See "Certain Transactions" and "Principal and Selling
Stockholders."
    
 
   
FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.
    
 
     The market price of our common stock could drop due to sales of a large
number of shares of our common stock in the market after the offering or the
perception that such sales could occur. These factors could also make it more
difficult to raise funds through future offerings of common stock. See "Shares
Eligible for Future Sale."
 
   
     After the offering,           shares of common stock will be outstanding.
Of these shares, the           shares to be sold in the offering will be freely
transferable and may be sold without restriction under the Securities Act,
except for any shares acquired by an "affiliate" of Azurix as defined in Rule
144 under the Securities Act. In connection with the offering, Azurix and the
selling stockholder (holding           shares of common stock post-offering)
have agreed, subject to certain exceptions, not to sell any shares of common
stock for a period of 180 days after the date of this prospectus without the
consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the
underwriters. Upon expiration of the lockup period,           shares may be sold
at any time subject to compliance with the volume limitations and other
restrictions of Rule 144. Options to purchase approximately 7.8 million shares
of common stock will also be outstanding after the offering. Such options
generally provide for vesting over a three to five year period. In addition,
more options may be granted in the future. See "Management -- Stock Plan."
    
 
     After the offering, we intend to file a registration statement covering the
sale of approximately 7.8 million shares of common stock reserved for issuance
under our stock plan. In addition, Atlantic Water Trust has registration rights
for all of its shares of common stock. See "Certain Transactions" and "Shares
Eligible for Future Sale."
 
   
     Marlin Water Trust, or the trustee under its senior notes indenture, may be
required to cause Atlantic Water Trust to sell shares of our common stock owned
by Atlantic Water Trust if the senior notes of Marlin Water Trust have not been
repaid on or before December 15, 2001 or earlier if specified events occur.
These events include defaults under certain of Azurix's, Enron's or Marlin Water
Trust's debt obligations or a downgrading of Enron senior debt to below "Baa3"
by Moody's Investors Service, Inc., "BBB-" by Standard & Poor's Ratings Services
or "BBB-" by Duff & Phelps Credit Rating Co. and a decline in Enron's common
stock price below $37.84. The last sale price of Enron common stock, as reported
by the New York Stock Exchange, on May 4, 1999 was $76.19. Atlantic Water Trust
may also elect to sell shares of our common stock in advance of the December 15,
2001 maturity of the senior notes of Marlin Water Trust in order to fund the
prepayment of such debt. See "Principal and Selling Stockholders -- Atlantic
Water Trust."
    
 
   
OUR CERTIFICATE OF INCORPORATION CONTAINS PROVISIONS THAT COULD DISCOURAGE A
TAKEOVER.
    
 
   
     Our certificate of incorporation authorizes our Board of Directors to issue
preferred stock without stockholder approval. If our Board of Directors elects
to issue preferred stock, it could be more difficult for a third party to
acquire us. In addition, provisions of the certificate of incorporation, such as
a staggered board of directors and limitations on the removal of directors, no
stockholder action by written consent and
    
                                       15
<PAGE>   21
 
   
limitations on stockholder proposals at meetings of stockholders, could make it
more difficult for a third party to acquire control of us, even if such change
of control would be beneficial to stockholders. See "Description of Capital
Stock."
    
 
   
THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK AND OUR STOCK PRICE
MAY FLUCTUATE.
    
 
     There has not been a public market for our common stock. We will list the
common stock for trading on the New York Stock Exchange. We do not know the
extent to which investor interest in Azurix will lead to the development of a
trading market for the common stock or how the common stock will trade in the
future. The initial public offering price will be determined by negotiations
among us, Atlantic Water Trust, Enron and the underwriters. Investors may not be
able to resell their shares at or above the initial public offering price. See
"Underwriting."
 
   
     The price at which the common stock will trade depends upon a number of
factors, including our historical and anticipated operating results and general
market and economic conditions, some of which are beyond our ability to control.
Factors such as quarterly fluctuations in our financial and operating results,
developments affecting us, our customers, the water markets in which we compete
or the water industry, including the factors listed below under "Forward-Looking
Statements," also could cause the market price of the common stock to fluctuate
substantially. In addition, the stock market has from time to time experienced
extreme price and volume fluctuations. These broad market fluctuations may
adversely affect the market price of the common stock.

                           FORWARD-LOOKING STATEMENTS
    
 
     This prospectus contains forward-looking statements. All statements other
than statements of historical facts contained in this prospectus, including
statements regarding our future financial position, business strategy, budgets,
projected costs and plans and objectives of management for future operations,
are forward-looking statements. Although we believe our expectations reflected
in these forward-looking statements are based on reasonable assumptions, no
assurance can be given that these expectations will prove to have been correct.
Important factors that could cause actual results to differ materially from the
expectations reflected in the forward-looking statements include, among other
things:
 
     - Political developments in foreign countries
 
     - The ability to enter new water and wastewater markets in the United
       States and in other jurisdictions
 
     - The timing and extent of deregulation of water and wastewater markets in
       the United States and in other countries
 
     - Regulatory developments in the United States and in other countries,
       including tax legislation and regulations
 
     - The extent of efforts by governments to privatize water and wastewater
       industries
 
     - The timing and extent of changes in non-U.S. currencies and interest
       rates
 
     - The extent of success in acquiring water and wastewater assets and
       developing and managing water resources, including the ability to qualify
       for and win bids for water and wastewater projects
 
     - The timing and success of efforts to develop international water and
       wastewater infrastructure projects
 
     - The ability of counterparties to financial risk management instruments
       and other contracts with us to meet their financial commitments to us
 
     - Our success in implementing our Year 2000 plan, the effectiveness of our
       Year 2000 plan and the Year 2000 readiness of third parties
 
     - Our ability to access the debt and equity markets during the periods
       covered by the forward-looking statements, which will depend on general
       market conditions and our credit ratings for our debt obligations
 
     We undertake no obligation to update or revise our forward-looking
statements, whether as a result of new information, future events or otherwise.
In light of these risks, uncertainties and assumptions, the forward-looking
events discussed in this prospectus might not occur.

                                USE OF PROCEEDS
 
     We expect the proceeds to Azurix from this sale of common stock to be
approximately $350 million, before deducting underwriting discounts and
commissions and estimated expenses. Azurix will not receive any proceeds from
the sale of common stock by the selling stockholder.
 
   
     We intend to use the net proceeds that we receive to repay approximately
$70 million that Enron advanced to us to fund our general, administrative and
operating expenses, from our inception through April 30, 1999, in addition to
certain capital expenditures. This includes $28.5 million advanced to us by
Enron to fund our acquisition of, and loan to, our investment in Cancun. The
amount due to Enron is non-interest bearing and has no maturity date.
    
 
   
     We intend to use $  million of the net proceeds to repay indebtedness to be
drawn under the new senior credit facility to be entered into in May 1999 by
Azurix Europe Ltd, an indirect, wholly owned subsidiary of Azurix and the
holding company for Wessex. The amounts to be drawn under the new senior credit
facility will bear interest at a floating London interbank offered rate, plus a
margin. The new senior credit facility is for a period of three years. We intend
to incur indebtedness under the new senior credit facility for the following
purposes:
    
 
   
     - To repay $       million outstanding under Azurix Europe's existing
       senior credit facility entered into to finance the acquisition of Wessex
    
 
   
     - To finance $107 million in connection with the acquisition of Philip
       Utilities Management Corporation, which is expected to close in the
       second quarter of 1999
    
 
   
     Any remaining proceeds will be used for working capital and general
corporate purposes. Pending such uses, we intend to invest the remaining
proceeds of the offering in short-term, investment-grade, interest-bearing
securities.
    
 
   
     See "Description of Indebtedness" for a description of the terms of the new
senior credit facility and the existing senior credit facility.
    
 
                                DIVIDEND POLICY
 
     We have not paid any dividends on our common stock and we do not currently
anticipate paying any dividends on our common stock. We currently intend to
retain all future earnings to fund the development and growth of our business.
The payment of any future dividends will be at the discretion of our Board of
Directors and will depend on our results of operations, financial condition,
capital requirements and other factors deemed relevant by our Board of
Directors.

                                    DILUTION
 
     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the net tangible book value per share of our common stock after
the offering. We calculate net book value per share by dividing the net assets
(total assets less liabilities) by the number of shares outstanding before the
offering. We calculate net tangible book value per share by dividing the net
tangible assets (total assets less liabilities and net intangible assets) by the
number of shares of common stock outstanding before the offering.
 
     The net book value and net tangible book value of Azurix as of December 31,
1998 were approximately $16.46 and $7.57 per share, respectively. Without taking
into account any changes in net book value or net tangible book value after
December 31, 1998, other than to give effect to the offering and the application
of the estimated net proceeds from the offering, the pro forma net book value of
the common stock as of December 31, 1998 would have been approximately $
million, or $       per share, and the pro forma net tangible book value of the
common stock as of such date would have been approximately $     million, or
$     per share. Assuming the offering had occurred at December 31, 1998, an
immediate increase in net book value of $     per share and an immediate
dilution of $     per share to new investors would have occurred. The following
table shows the effect of the offering as if the offering had occurred at
December 31, 1998 and illustrates the immediate increase in net tangible book
value of $     per share and an immediate dilution of $     per share to new
investors:

(1) If the underwriters' over-allotment option is exercised in full, sales by
    the selling stockholder in the offering will reduce the number of shares of
    common stock held by the existing stockholder to approximately   % of the
    total shares of common stock outstanding after the offering and will
    increase the number of shares held by new investors to           , or
    approximately   % of the total shares of common stock outstanding after the
    offering. See "Underwriting."
 
     The foregoing table excludes outstanding employee stock options of Azurix
to purchase approximately 7.8 million shares of common stock. The terms of the
options provide for vesting, generally over a three to five year period.
However, assuming all options are exercised, additional dilution to new
stockholders would be approximately $     per share.

                  SELECTED HISTORICAL AND UNAUDITED PRO FORMA
                          CONSOLIDATED FINANCIAL DATA
 
    The following tables present selected historical consolidated financial data
for Azurix and for Wessex, the predecessor of Azurix, for the periods and dates
indicated. In addition, the tables present selected unaudited pro forma
consolidated financial data for Azurix for the year ended December 31, 1998.
 
   
    The historical financial data for Azurix are derived from Azurix's audited
consolidated financial statements included elsewhere in this prospectus and
includes the impact of the Wessex acquisition from the date of acquisition. All
of Azurix's results of operations occurred in the fourth quarter of 1998,
subsequent to the acquisition of Wessex. The historical financial data for
Wessex as of March 31, 1998 and for the years ended March 31, 1997 and 1998 and
for the six months ended October 2, 1998 are derived from Wessex's audited
consolidated financial statements included elsewhere in this prospectus. The
historical financial data for Wessex as of March 31, 1995, 1996 and 1997 and for
the years ended March 31, 1995 and 1996 are derived from unaudited financial
statements prepared in accordance with U.S. generally accepted accounting
principles that were derived from Wessex's audited financial statements prepared
in accordance with U.K. generally accepted accounting principles.
    
 
    The unaudited pro forma financial data for Azurix are derived from the
unaudited condensed consolidated pro forma financial information included
elsewhere in this prospectus. The unaudited pro forma financial data give effect
to the acquisition of Wessex, the redemption and elimination of Wessex's
preference shares for an aggregate price of $249.8 million and the sale by
Wessex of its interest in UK Waste for $337.9 million, as though each occurred
on January 1, 1998. The unaudited pro forma financial data presented below is
not necessarily indicative of the financial results that would have occurred had
the acquisition of Wessex, the redemption and elimination of Wessex's preference
shares and the sale by Wessex of its interest in UK Waste occurred on January 1,
1998 and should not be viewed as indicative of operations in future periods.
 
    This information should be read in conjunction with "Capitalization,"
"Unaudited Condensed Consolidated Pro Forma Financial Information,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Consolidated Financial Statements of Azurix and Wessex and
related notes thereto included elsewhere in this prospectus.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
     The following information should be read in conjunction with the
information contained in the Consolidated Financial Statements of Azurix and
Wessex and related notes thereto and the Unaudited Condensed Consolidated Pro
Forma Financial Information of Azurix and related notes thereto included
elsewhere in this prospectus.
 
OVERVIEW
 
   
     Azurix was incorporated on January 29, 1998. All of its operating results
and cash flows occurred during the fourth quarter of 1998 following the Wessex
acquisition. During 1998, Azurix indirectly acquired all of the outstanding
ordinary share capital of Wessex, and Enron contributed to Azurix the
outstanding common stock of a subsidiary that in June 1998 acquired an indirect
32.1% ownership interest in Obras Sanitarias Mendoza S.A. Wessex and Obras
Sanitarias Mendoza provide water and wastewater treatment services in
southwestern England and the Province of Mendoza, Argentina, respectively. In
December 1998, Enron contributed Azurix to Atlantic Water Trust and Marlin Water
Trust acquired a 50% voting interest in Atlantic Water Trust. Enron retained a
50% voting interest in Atlantic Water Trust.
    
 
BUSINESS ACQUISITION
 
   
     On October 2, 1998, Azurix, through its indirect wholly owned subsidiary,
Azurix Europe, acquired over 90% of the outstanding ordinary share capital of
Wessex. On that same date, Azurix Europe issued notices to the remaining Wessex
ordinary stockholders, informing them that it intended to exercise its rights
under the English Companies Act to acquire compulsorily all of the outstanding
ordinary shares not held by Azurix Europe. The compulsory share acquisition was
completed in November 1998. The per share price paid to Wessex shareholders was
L6.30. The total cost of the Wessex acquisition, including transaction costs,
was $2.4 billion, plus the assumption of $481.5 million of existing Wessex debt.
The cost included cash consideration paid to Wessex shareholders, net of $1.7
million cash acquired, and the issuance of loan notes to Wessex shareholders in
the face amount of $119.8 million. The acquisition was financed through capital
contributions from Azurix's parent company totaling $1.6 billion and the
issuance of $0.8 billion in debt by Azurix Europe. Wessex had cumulative
mandatorily redeemable preference shares outstanding when it was acquired.
Wessex redeemed these shares in December 1998 for a cash payment of $106.4
million.
    
 
SALE OF INVESTMENT IN UNCONSOLIDATED AFFILIATE
 
   
     On November 30, 1998, Wessex sold its 50% interest in Wessex Waste
Management Ltd, a joint venture with Waste Management International Plc that
does business as UK Waste, for $337.9 million in cash. Azurix recorded no gain
or loss from the sale.
    
 
RECENT DEVELOPMENTS
 
   
     Azurix entered into an agreement on December 19, 1998 to purchase 49.9% of
an entity whose principal asset is the water concession for the city of Cancun,
Mexico. This agreement was not binding until material conditions were met, and
these conditions were met or waived subsequent to December 31, 1998. The
purchase price was $13.5 million, paid on March 24, 1999. In addition, Azurix
has agreed to provide up to $25.0 million in debt financing, $15.0 million of
which was funded on February 25, 1999.
    
 
   
     Azurix entered into an agreement on March 25, 1999 to acquire 100% of the
stock of Canadian-based Philip Utilities Management Corporation for $107
million. Philip Utilities is a water and wastewater services company in the
United States and Canada that provides operations and management, engineering,
residuals management and underground infrastructure development services for
municipal water and wastewater facilities. The acquisition is subject to
regulatory and municipal approvals and other third party consents and is
expected to close in the second quarter of 1999.

     On March 30, 1999, Azurix, through subsidiaries of Wessex, completed a U.K.
pounds sterling denominated bond offering in the amount of $483.5 million.
Wessex used $448.4 million of the proceeds from the sale of the 10-year bonds to
repay all outstanding amounts under its former bank credit facilities as well as
all outstanding amounts under uncommitted credit facilities. Any remaining
proceeds were available for general corporate purposes. The bonds mature March
30, 2009 and bear interest of 5.875% payable annually. See "Description of
Indebtedness."

     Operating revenues are derived from water supplied and wastewater treated
for residential, commercial and industrial customers. The supply of water is
either metered, known as measured, or unmeasured. The charge for wastewater
treated is based upon a percentage of the water supplied and charged to that
customer. These services account for approximately 90% of total operating
revenues.
    
 
   
     Wessex's subsidiary, SC Technology, sells and operates plants for drying
sludge, the solid waste remaining after wastewater is treated. The majority of
SC Technology's operating revenues are derived from projects related to selling
and managing the construction of plants, and therefore each period's operating
revenue fluctuates according to how many projects are in progress. Other
unregulated activities include the sale of electricity and treatment of organic
waste.
    
 
   
     Operations and maintenance expense consists of the costs of supplying water
and treating wastewater, including the costs of maintaining and operating the
plant and equipment used in these processes. The main categories of cost include
labor, power, rent, real estate taxes, chemicals, transport, equipment and
grounds maintenance, and tankering. SC Technology's costs relate to the
construction and delivery of the plant being installed, including the cost of
equipment, civil engineering, building and labor.
    
 
   
     General and administrative expense includes personnel costs, transaction
expenses related to due diligence and overhead associated with Azurix's pursuit
of acquisitions and development projects, in addition to support functions such
as billing and customer services, quality and scientific services, regulation,
finance, human resources and public relations.

     The functional currency of Wessex is U.K. pounds sterling. Accordingly, its
results of operations, translated into U.S. dollars, are affected by the change
in currency exchange rates when comparing periods. The actual average exchange
rates for each applicable period used in translating the U.K. pounds sterling
functional results to U.S. dollars, in accordance with U.S. GAAP, are $1.66 per
L1.00 for the year ended December 31, 1998, $1.65 per L1.00 for the six months
ended October 2, 1998, $1.64 per L1.00 for the year ended March 31, 1998 and
$1.59 per L1.00 for the year ended March 31, 1997.
    
 
   
 AZURIX UNAUDITED PRO FORMA FOR THE YEAR ENDED DECEMBER 31, 1998
    
 
   
     The following discussion is derived from the Unaudited Condensed
Consolidated Pro Forma Financial Information contained elsewhere in this
prospectus. The pro forma results discussed below include the 1998 results of
Wessex prior to its acquisition by Azurix.
    
 
   
     Operating revenues of $464.2 million were all derived from Wessex.
Approximately 91% of these revenues were derived from the sale of measured and
unmeasured water and wastewater services. Operating revenues from SC Technology,
and other unregulated activities, accounted for 5% and 4% of total operating
revenues, respectively.
    
 
   
     Operations and maintenance expense of $120.9 million was all incurred by
Wessex. Of this amount, $89.3 million relates to the costs of supplying water
and treating wastewater, including the costs of maintaining and operating plant
and equipment used in these processes, and $23.9 million relates to the costs of
the plants being installed by SC Technology.
    
 
   
     General and administrative expense of $44.4 million includes $12.6 million
of costs incurred by Azurix in the pursuit of acquisitions and development
projects. These costs were incurred in the fourth quarter of 1998 and are not
necessarily representative of the costs expected to be incurred on an annual
basis. In addition, $31.8 million of costs were incurred by Wessex from the
support functions of its day-to-day operations. Excluded from this amount is
$20.7 million incurred by Wessex in connection with, and prior to, its
acquisition by Azurix.
    
 
   
     Depreciation and amortization of $88.3 million includes $22.0 million for
the amortization of goodwill incurred by Azurix in the acquisition of Wessex.
All of the depreciation expense is derived from depreciation on the property,
plant and equipment of Wessex. The goodwill amortization and depreciation
expense related to Wessex is based on a preliminary purchase price allocation.
    
 
  AZURIX -- DATE OF INCEPTION TO DECEMBER 31, 1998
 
   
     Azurix was incorporated on January 29, 1998. All of its operating revenues
and operating income occurred in the fourth quarter of 1998 following the Wessex
acquisition.
    
 
   
     Operating revenues of $119.7 million were derived from Wessex.
Approximately 90% of these revenues relate to the sale of measured and
unmeasured water and wastewater services. SC Technology operating revenues, and
operating revenues from unregulated activities, accounted for 6% and 4% of total
operating revenues, respectively.
    
 
   
     Operations and maintenance expense of $31.6 million were all incurred by
Wessex. Of this amount, $23.0 million relates to the cost of supplying water and
treating wastewater, including the costs of maintaining and operating plant and
equipment used in these processes, and $7.2 million relates to the costs of the
plants being installed by SC Technology.
    
 
   
     Azurix's general and administrative expenses include $7.7 million related
to Wessex's operations and $12.6 million related to the pursuit of acquisitions
and development projects. The expenses related to acquisitions and development
projects stem from a business strategy initiated in the fourth quarter of 1998.
    
 
   
     Depreciation and amortization of $22.2 million includes $5.5 million for
the amortization of goodwill incurred by Azurix in the acquisition of Wessex.
All of the depreciation expense is derived from depreciation on the property,
plant and equipment of Wessex. The goodwill amortization and depreciation
expense related to Wessex is based on a preliminary purchase price allocation of
Wessex.
    
                                       26
<PAGE>   32
 
     Interest expense is related to the Wessex acquisition financing, existing
Wessex debt and funds borrowed in the fourth quarter to redeem the outstanding
preference shares.
 
   
     The effective tax rate for the period was 64.2%. The difference between the
effective tax rate and the U.S. statutory rate of 35% (U.K. statutory rate of
31%) is primarily related to the following:
    
 
   
     - A valuation allowance recognized on a U.S. deferred tax asset generated
       from general and administrative expense incurred in the United States
    
 
   
     - A valuation allowance recognized on a U.K. deferred tax asset relating to
       non-deductible interest expense prior to achieving a consolidated tax
       position
    
 
   
     - Non-deductible amortization of goodwill resulting from the acquisition of
       Wessex
    
 
  WESSEX (PREDECESSOR COMPANY) SIX MONTHS ENDED OCTOBER 2, 1998 COMPARED TO THE
YEAR ENDED
  MARCH 31, 1998
 
   
     Operating revenues for the six months ended October 2, 1998 decreased by
$202.8 million, or 46.4%, when compared to the fiscal year ended March 31, 1998,
primarily as a result of six months less operating revenues in the current
period, partially offset by a 5.8% increase in the pricing formula contained in
the Wessex license, effective April 1, 1998.
    
 
   
     Operations and maintenance expense for the six months ended October 2, 1998
decreased by $49.2 million, or 44.4%, when compared to the fiscal year ended
March 31, 1998, primarily as a result of six months less activity during the
current period.
    
 
   
     General and administrative expense for the six months ended October 2, 1998
increased by $7.3 million, or 25.1%, when compared to the fiscal year ended
March 31, 1998, primarily as a result of $20.7 million incurred by Wessex
related to its acquisition by Azurix. These expenses were incurred prior to the
consummation of the acquisition. This was partially offset by six months less
activity in the six months ended October 2, 1998.
    
 
   
     Depreciation and amortization expense for the six months ended October 2,
1998 decreased by $29.1 million, or 45.3%, when compared to the fiscal year
ended March 31, 1998, primarily as a result of six months less expense incurred
during the six months ended October 2, 1998, partially offset by increased
depreciation due to property additions resulting from Wessex's capital
expenditure program.
    
 
   
     Equity earnings of affiliates for the six months ended October 2, 1998
decreased by $7.5 million, or 56.4%, when compared to the fiscal year ended
March 31, 1998, primarily as a result of six months less earnings accumulated
and increased operations and maintenance expense associated with a new recycling
division.
    
 
   
     Net interest expense for the six months ended October 2, 1998 decreased by
$2.5 million, or 29.1%, when compared to the fiscal year ended March 31, 1998,
primarily as a result of six months less activity. This decrease was partially
offset by a reduction in the average cash and cash equivalent position deposited
in interest bearing investments in the six months ended October 2, 1998 which
resulted from the payment of the first installment of the one-time utility tax
in December 1997 and the preference share redemption in 1998.
    
 
   
     Income tax and utility tax expense for the six months ended October 2, 1998
decreased by $191.9 million, or 87.1%, when compared to the fiscal year ended
March 31, 1998, primarily as a result of a one-time utility tax of $162.3
million levied in the year ended March 31, 1998 and six months less taxable
income in the six months ended October 2, 1998. The utility tax was introduced
in the Finance (No. 2) Act 1997, is referred to in legislation as the Windfall
Tax, and was levied on privatized utilities including the water and electricity
sectors. It is a one-time tax in that the tax legislation only relates to this
assessment and new legislation would have to be enacted for any additional
windfall tax. In addition, the U.K. Government has stated that it was a one-time
tax.
    
 
                                       27
<PAGE>   33
 
   
     The calculation of utility tax was based on the profit after tax of Wessex
for the average of the four years ended March 31, 1994, multiplied by a price
earnings ratio of nine. The resulting amount was compared to the value of Wessex
at the date of initial trading of its stock in 1989, and the difference was
deemed to be windfall profits and was taxed at a 23% rate.
    
 
  WESSEX (PREDECESSOR COMPANY) YEAR ENDED MARCH 31, 1998 COMPARED TO THE YEAR
ENDED
  MARCH 31, 1997
 
   
     Operating revenues for the fiscal year ended March 31, 1998 increased by
$33.5 million, or 8.3%, when compared to the fiscal year ended March 31, 1997,
primarily as a result of a 4.6% increase in the pricing formula contained in the
Wessex license, effective April 1, 1997, which resulted in $17.9 million of
additional operating revenues. In addition, operating revenues from SC
Technology increased by $4.2 million due to a higher number of construction
projects in progress during the year ended March 31, 1998.
    
 
   
     Operations and maintenance expense for the year ended March 31, 1998
increased by $8.5 million, or 8.3%, when compared to the year ended March 31,
1997, primarily due to higher operating expenses from SC Technology due to a
higher number of construction projects in progress in the year ended March 31,
1998.
    
 
   
     General and administrative expense for the year ended March 31, 1998
decreased by $3.1 million, or 9.6%, when compared to the year ended March 31,
1997, primarily due to cost reduction measures implemented by Wessex, and costs
of $2.1 million incurred in the year ended March 31, 1997 related to an
unsuccessful attempt to acquire a third party.
    
 
   
     Depreciation and amortization expense for the year ended March 31, 1998
increased by $6.3 million, or 10.9%, when compared to the year ended March 31,
1997. Substantially all of this increase is due to property additions resulting
from Wessex's capital expenditure program.
    
 
   
     Equity earnings of affiliates for the year ended March 31, 1998 decreased
by $1.4 million, or 9.5%, when compared to the year ended March 31, 1997. This
decrease resulted from a lower sales margin due to increased competition, and
higher general and administrative expense related to the hiring of additional
sales staff.
    
 
   
     Net interest expense was $8.6 million for the year ended March 31, 1998, as
compared to net interest income of $10.2 million for the year ended March 31,
1997, primarily due to a reduction in the cash and cash equivalent position in
the current period as a result of the buy-back of its "B" and "C" classes of
ordinary shares in February 1997.
    
 
   
     Income tax and utility tax expense for the year ended March 31, 1998 as
compared to the year ended March 31, 1997, increased by $137.9 million primarily
as a result of a one-time tax levied on privatized utilities in the year ended
March 31, 1998 of $162.3 million. The effect of the utility tax was partially
offset by a change in the U.K. statutory tax rate from 33% to 31% during the
year ended March 31, 1998, which amounted to $22.6 million.
    
 
OUTLOOK
 
     Several developments may significantly affect Azurix's future results of
operations.
 
   
     Azurix has a business strategy consisting of growth through acquisitions
and development projects. We have recently put in place a business development
effort requiring an increase in personnel to pursue and support acquisition and
privatization activity on a global scale. As of February 28, 1999, Azurix had
hired approximately 145 employees. The associated general, administrative and
operating expenses are approximately $15 million pre-tax on a quarterly basis.
    
 
   
     Most of our operating revenues are subject to governmental regulation of
the rates that we may charge to our customers. The U.K. government is currently
conducting a periodic review of the price limits for water and wastewater
companies in England and Wales that is expected to result in new price limits
    
                                       28
<PAGE>   34
 
   
for the period from April 1, 2000 through 2005. In October 1998, the Director
proposed an initial price cut for Wessex in excess of 17.5% from 1999-2000 to
2000-2001, with prices gradually increasing thereafter but remaining below the
1999-2000 levels in 2004-2005. Following this proposal, the U.K. Government
announced its decision to require greater capital expenditures for water and
wastewater companies for environmental improvements. Subsequently, in its April
1999 business plan filed with the Director, Wessex proposed stable prices from
1999-2000 to 2000-2001, with prices gradually increasing to 18% higher than
current levels in 2005, primarily to fund capital expenditures mandated by the
new environmental standards. The Director has stated that he will publish draft
price limits in July 1999 with the final determination being made in November
1999. Although we are unable to predict the precise outcome of the current U.K.
rate review, if Wessex were required to cut its prices as originally proposed by
the Director, Wessex's operating revenues would be reduced by approximately
17.5% and its earnings would be reduced materially. However, we would not expect
that this would have a material adverse effect on Azurix's financial position.
At the time of the acquisition of Wessex, we took into consideration the pending
rate review in our valuation of Wessex.
    
 
   
     We anticipate refinancing a portion of our existing debt in May 1999,
potentially resulting in a one-time non-cash charge of $9.8 million ($6.9
million after-tax) in the second quarter due to the write-off of deferred
financing costs. We will incur approximately $     million in financing costs
related to the proposed new financing.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     All of Azurix's cash flows for the period from inception to December 31,
1998 occurred in the fourth quarter following the Wessex acquisition. Cash flow
from operations totaled $4.4 million during the period from January 29, 1998 to
December 31, 1998. Related to its investment activities, Azurix used $2,270.8
million, in addition to the issuance of $119.8 million of acquisition loan
notes, to acquire ordinary shares of Wessex and $63.2 million for capital
expenditures incurred by Wessex. In addition, Azurix received $337.9 million in
proceeds from the sale of UK Waste. Cash provided by financing activities during
the period totaled $1,977.5 million, primarily comprised of $1,600.2 million
from the issuance of common stock and capital contributions and a net increase
in borrowings of $485.4 million, partially offset by the redemption of the
Wessex preference shares of $106.4 million. Cash received from the issuance of
common stock of $1.0 million and capital contributions of $1,599.2 million are
from Azurix's former parent company, Enron Water (Holding) L.L.C.
    
 
   
     At December 31, 1998, Azurix had a working capital deficit of $129.6
million. Approximately 60% of Azurix's operating revenues are derived from
customers whose billings are not based on the delivery of a measured volume of
service. These customers are billed semiannually in advance. Funds received in
advance as of December 31, 1998, where the service has not been provided,
totalled $71.0 million and are reflected on the Consolidated Balance Sheet as
deferred income. This component of the working capital deficit does not require
the future use of cash but is recognized in income over the remaining service
period covered by the billings. The remaining working capital deficit is related
to the timing of cash payments. Excess cash, including funds received in
advance, is used to pay down short-term revolving bank credit facilities. The
funds are re-borrowed under these credit facilities when needed to pay current
obligations. At December 31, 1998, Azurix had available capacity, under its
existing credit facilities, to provide $91.5 million of working capital.
Management believes that cash flows from operations and the available capacity
under credit facilities is sufficient to fund the working capital deficit.
    
 
   
     At December 31, 1998, Azurix, through Azurix Europe, had in place a senior
credit facility consisting of a term loan facility of $322.6 million and a
revolving credit facility of $575.3 million. The amounts outstanding at December
31, 1998 were $211.2 million under the term loan facility and $8.3 million under
the revolving credit facility. As a result, Azurix had total availability under
the senior credit facility of $678.4 million, consisting of $567.0 million under
the revolving credit facility and $111.4 million under the term loan facility.
Of the $567.0 million under the revolving credit facility, $91.5 million was
permitted, if required, to fund the working capital deficit that existed at year
end. The term loan capacity of
    
 
                                       29
<PAGE>   35
 
$111.4 million is used to secure a substantial portion of the acquisition loan
notes issued to Wessex shareholders in lieu of cash consideration for their
shares.
 
   
     In May 1999, Azurix, through Azurix Europe, intends to enter into a new
$686.0 million senior credit facility with a group of banks. Proceeds under the
facility will be used to refinance Azurix Europe's existing indebtedness and to
make loans to affiliates of Azurix Europe for the purpose of financing
acquisitions of and investments in water and wastewater assets and businesses.
We expect that, of the $686.0 million facility amount, $298.6 million will be
available to refinance existing debt of Azurix Europe and $387.4 million may be
lent to affiliates. This borrowing capacity, combined with cash flows from
assets acquired, will be used by Azurix to fund acquisitions and privatizations.
See "Description of Indebtedness" for detailed discussion of terms for all
credit facilities and loan agreements.
    
 
   
     Azurix, through Wessex, is a borrower under committed credit facilities
that provide an aggregate $399.1 million for general corporate purposes. As of
December 31, 1998, these bank facilities were completely drawn down. Wessex also
had $24.9 million outstanding under short-term uncommitted bank borrowings at
December 31, 1998. On March 30, 1999, Wessex issued $483.5 million principal
amount of 10-year bonds. Wessex used $448.4 million of the proceeds from the
sale of the bonds to repay all outstanding amounts under its former bank credit
facilities as well as all outstanding amounts under uncommitted credit
facilities. Excess proceeds were available for general corporate purposes.
    
 
   
     Azurix, through Wessex, maintains an ongoing asset replacement program
throughout its customer service areas based on an expenditure plan submitted to
the U.K. industry regulator. Wessex expects that its projected capital
expenditures of approximately $230 million for 1999 will be financed with
internally generated funds and from proceeds under long-term and short-term
borrowing arrangements. Included in this amount are contractual commitments for
capital expenditures to be incurred after December 31, 1998 of $130.2 million.
The projected capital expenditures consist primarily of the following:
    
 
   
     - Approximately $135 million for wastewater projects, such as construction
       of wastewater treatment facilities and improvements to existing
       facilities
    
 
   
     - Approximately $45 million for water supply projects, such as construction
       of water treatment facilities and installation of water mains
    
 
   
     - Approximately $25 million for office space construction in the United
       Kingdom
    
 
   
     - Approximately $20 million related to information technology investment
    
 
   
     In addition, in connection with the pending acquisition of Philip
Utilities, Azurix has committed $107 million to fund the purchase price. Azurix
intends to utilize funds drawn under the new senior credit facility for this
purpose. The acquisition is expected to close in the second quarter of 1999.
    
 
FINANCIAL RISK MANAGEMENT
 
   
     Azurix is exposed to market risks, particularly changes in U.S. and
international interest rates and changes in currency exchange rates as measured
against the functional currencies in which it operates. Azurix engages in
hedging programs aimed at limiting the impact of significant and sudden
fluctuations, but there can be no assurance that such an approach will be
successful. Factors that could impact the effectiveness of its hedging programs
include the accuracy of revenue forecasts, volatility of the currency and
interest rate markets, and the availability of hedging instruments. Azurix
utilizes swap contracts to manage interest rate risk. Currency exchange rate
risk is the result of transactions that are denominated in a currency other than
the functional currencies in which we operate. The primary purpose of Azurix's
foreign currency hedging activities is to manage the volatility associated with
currency exchange rates. We manage these risks by utilizing derivative financial
instruments for non-trading purposes. Azurix enters into currency or interest
rate contracts for the sole purpose of hedging an existing or anticipated
exposure, not for speculation. Azurix's accounting policies for, and the
significant terms of, derivative financial instruments are described in Note 1
and Note 8, respectively, to the Consolidated Financial Statements.
    
 
                                       30
<PAGE>   36
 
   
     Azurix uses J.P. Morgan's RiskMetrics(TM) system to estimate the
value-at-risk of its financial instruments. Value-at-risk is a statistical
estimate of the loss that would result from changes in market prices.
Value-at-risk is based on volatility and correlation data provided by J.P.
Morgan, a statistical confidence level and an estimate of the time period
required to liquidate the positions in the various financial instruments. The
value-at-risk estimate was based on normal market conditions, a 95% confidence
level and a liquidation period between 30 days and 60 months, depending on the
type of financial instrument. At December 31, 1998, the value-at-risk estimate
for foreign currency and interest rate exposure was $0.7 million and $0.9
million, respectively. The value-at-risk estimate includes only the risk related
to the financial instruments that serve as hedges and does not include the
related underlying hedged item. Judgment is required in interpreting market data
and the use of different market assumptions or estimation methodologies that
will affect the estimated value-at-risk amount.
    
 
YEAR 2000
 
     The Year 2000 problem results from the use in computer hardware and
software of two digits rather than four digits to define the applicable year.
The use of two digits was a common practice for decades when computer storage
and processing was much more expensive than it is today. When computer systems
process dates both before and after January 1, 2000, two-digit year "fields" may
create processing ambiguities that can cause errors and system failures. For
example, computer programs that have date sensitive features may recognize a
date represented by "00" as the year 1900, instead of 2000. These errors or
failures may have limited effects, or the effects may be widespread, depending
on the computer chip, system or software, and its location and function.
 
   
     The effects of the Year 2000 problem are exacerbated because of the
interdependence of computer and telecommunications systems in the United States
and throughout the world. This interdependence applies to Azurix and Azurix's
suppliers, trading partners and customers and to governments of countries where
Azurix does business. This interdependence also applies to Enron, on which
Azurix relies for services as described under "Certain Transactions."
    
 
  State of Readiness
 
     We intend to follow Enron's Year 2000 plan, which covers all of Enron's
business units. The aim of the Enron plan is to take reasonable steps to prevent
Enron's mission-critical business functions from being impaired due to the Year
2000 problem. As used in this prospectus, "mission-critical" functions refer to
the critical functions whose loss would cause significant injury to persons or
tangible property, or an immediate stoppage of or significant impairment to
business areas of material importance. Enron intends to modify its plan as
events warrant. In addition, we intend to adapt the Enron plan to our
operations. Among other things, we intend to conform Wessex's Year 2000 efforts
to the Enron plan and to introduce this plan to our operations in Cancun.
 
   
     Central information systems, such as large mainframes and midsize computer
systems at Wessex and desktop or personal computers and computer networks, can
be vulnerable to Year 2000 problems. In addition, devices with chips embedded in
them, such as flow controllers and controllers for automated pumps, are
vulnerable to Year 2000 problems. Devices with chips embedded in them may be
used for many purposes, and finding all of them may be difficult, even with a
careful inventory and remediation process. In addition, we are concerned with
the systems of external entities over which we do not have control. Examples of
these systems include central information systems and embedded devices of our
suppliers and contractors, financial institutions, governments in locations
where we operate, customers and co-venturers.
    
 
   
     In general, the Enron Year 2000 Plan adopted by Azurix includes phases of
awareness, inventory, remediation, verification and testing, and contingency
planning. These steps describe a process that continues to go in cycles. For
example, we will continue to refine our inventory of central information systems
and embedded devices until the early days and, if necessary, weeks of January
2000, to identify Year 2000-related problems that require fixing.
    
 
                                       31
<PAGE>   37
 
     Under the Enron plan, Wessex will continue to:
 
     - Inventory its mission-critical computer hardware and software systems and
       embedded chips, i.e., computer chips with date related functions,
       contained in a wide variety of devices, that in turn are installed in a
       wide variety of equipment and that may fail to function or may function
       improperly before, on or after January 1, 2000
 
     - Assess the effects of Year 2000 problems on its mission-critical
       functions
 
     - Remedy to the maximum extent practicable material disruptions or other
       material adverse effects on its mission-critical functions, processes and
       systems
 
     - Verify and test the mission-critical systems to which remediation efforts
       have been applied
 
     - Attempt to limit the adverse effect of Year 2000 problems that cannot
       reasonably be remediated by January 1, 2000, including developing
       contingency plans to minimize Year 2000 problems that have not been
       identified or fixed by January 1, 2000
 
   
     Wessex has completed most of the stages of the Enron Plan and will be Year
2000 ready by July 31, 1999 as shown in the following table:

     We are pursuing additional concessions, outsourcing contracts and other
water and wastewater projects. We expect that we will adapt the Enron plan to
cover our additional operations.
 
     The Enron plan recognizes that the computer, telecommunications and other
systems of outside entities have the potential to adversely affect the conduct
of our business. We do not have control of these outside entities or outside
systems. However, the Enron plan includes an ongoing process of contacting
outside entities whose systems have, or may have, a substantial effect on the
ability of each of the relevant businesses to continue to conduct its
mission-critical functions without disruption from Year 2000 problems. The Enron
plan envisions attempting to inventory and assess the extent to which these
outside systems may not be "Year 2000 ready" or "Year 2000 compatible." This
refers to the ability of a system to process data reliably, both before and
after January 1, 2000, without disruption due to an inability to process date
information reliably. This is distinguished from "Year 2000 compliant," which
implies that a system will work properly, both before and after January 1, 2000,
even if outside systems fail to operate properly. In implementing the Enron
plan, we will attempt to coordinate our efforts to prepare for the Year 2000
problem with outside entities.
 
   
     As of March 15, 1999, Wessex had substantially finished identifying and
assessing its mission-critical central information systems and devices with
embedded chips. Wessex is continuing to analyze, convert and test its
mission-critical central information systems and devices with embedded chips. In
addition, Wessex has contacted all outside entities upon which it relies for
mission-critical functions.
    
 
   
     We do not have operational control of the Mendoza concession. Therefore, we
consulted with SAUR, the operator of the concession, to develop an understanding
of SAUR's Year 2000 efforts at Mendoza.

     The mission-critical systems at the Mendoza concession include business
systems, such as a customer interface system and a payroll system, and devices
with embedded chips such as flow meters and a supervisory, control, and data
acquisition system. Mission-critical external entities include the local
electrical utility for power to supply water pumps, the local telephone company
and local banks that function as collection agents. Although employees of SAUR
plan to visit mission-critical external entities, we cannot assure that the
systems of these external entities will be free from disruptions due to Year
2000 problems, and SAUR cannot ensure that the Mendoza facility will be free
from mission-critical disruptions as a result. We anticipate that SAUR will
include these mission-critical external dependencies in its contingency
planning.
    
 
   
     The Cancun concession is in the early stages of adopting and implementing
the Enron plan for Year 2000 readiness. The concessionaire will inventory,
assess, analyze, convert and test the Cancun systems for Year 2000 readiness and
develop Year 2000 contingency plans to minimize Year 2000 problems that have not
manifested themselves or have not been corrected by January 1, 2000. The
schedule for this implementation is as follows:

     The Cancun concession has a mission-critical dependency on the local
electric utility and on local banks. Although employees of the concessionaire
plan to visit these mission-critical external entities, we cannot ensure that
the systems of these external entities will be free from disruptions due to Year
2000 problems. As a result, we cannot be certain that the Cancun facility will
be free from mission-critical disruptions. Azurix will include these external
dependencies in its contingency planning.
    
 
   
     We believe that Wessex's and the Cancun concession's mission-critical
systems will be Year 2000 ready substantially before January 1, 2000. However,
unforeseen circumstances could arise during the implementation of the Enron plan
that could adversely affect Enron's, Wessex's or the Cancun concession's
mission-critical functions, thereby disrupting or materially adversely affecting
Azurix's business.
    
 
  Costs to Address Year 2000 Issues
 
   
     As of April 30, 1999, we have not incurred material costs for Year 2000
issues, and we do not anticipate incurring material costs in implementing the
plan or preparing Year 2000 contingency plans. However, there can be no
assurance that the actual costs of implementing the plan will not exceed our
estimates or that our business will not be materially adversely affected by Year
2000 issues.

  Year 2000 Risk Factors
 
     We plan to satisfy applicable regulatory requirements with respect to Year
2000 readiness. However, failure to comply with such requirements may cause a
regulatory authority to order the cessation of our operations, which could have
a material adverse affect on our business.
 
     As the Year 2000 approaches, there will be increased competition for people
with the technical skills necessary to deal with Year 2000 problems. While we
intend to recruit and retain a sufficient number of people with those skills,
the shortages of skilled personnel could prevent us from doing so. In addition,
we may face shortages of other resources, such as Year 2000 ready computer chips
or components. These shortages might delay or otherwise impair our ability to
assure that our mission-critical systems are Year 2000 ready.
 
   
     We will rely on Enron for services that involve computer processing. These
Enron systems are mainframe systems used for functions such as asset management,
accounting and human resources. Enron believes that its mission-critical systems
will be Year 2000 ready substantially before January 1, 2000. In addition, we
believe that Wessex's mission-critical systems will be Year 2000 ready
substantially before January 1, 2000. However, unforeseen circumstances could
arise during the implementation of the Enron plan that could adversely affect
Enron's or Wessex's mission-critical functions, thereby disrupting or materially
adversely affecting Azurix's business.
    
 
   
     We are taking reasonable steps to identify, assess, and where necessary,
replace devices containing embedded chips. Despite these efforts, we anticipate
that we will not be able to find and replace all the devices with embedded chips
or embedded chips in our systems. Further, we anticipate that outside entities
on which we depend will also not be able to find and replace all devices with
embedded chips or embedded chips in their systems. Some of the embedded chips
that fail to operate or that produce improper results may create system
disruptions or failures. Some of these disruptions or failures may spread from
the systems in which they are located to other systems. These failures may have
adverse effects upon our ability to maintain safe operations and may also have
adverse effects upon our ability to serve our customers, to comply with
environmental statutes and regulations, and to otherwise fulfill contractual and
other legal obligations. The embedded chip problem is widely recognized as one
of the more difficult aspects of the Year 2000 problem. Therefore, the possible
adverse impact of the embedded chip problem is not, and will not be, unique to
Azurix.
    
 
   
     The external entities we are contacting include suppliers, customers,
financial institutions, and governmental entities. We intend to meet with many
external entities that are mission-critical to Azurix for Year 2000 purposes.
However, we cannot in any way ensure that these external entities will be Year
2000 ready, nor can we place complete reliance on any assurances, written or
verbal, from these entities that they expect to be Year 2000 ready.
    
 
     We cannot assure that suppliers upon which we depend for essential goods
and services will test their mission-critical systems in a timely manner.
Failure or delay by all or some of these entities, including U.S. and foreign
governments or governmental authorities, to assess their Year 2000 readiness
could create substantial disruptions having a material adverse effect on our
business.
 
     We have reviewed the most reasonably likely worst case Year 2000 scenarios
we may face. Analysis of these scenarios has led us to contemplate the following
possibilities that, although unlikely, could conceivably occur:
 
     - Widespread failure of electrical, gas and other utilities serving us
       domestically and internationally
 
     - Widespread disruption of communications
 
     - Disruption of transportation services for us and our employees,
       contractors, suppliers and customers
 
     - Disruption to our ability to gain access to, and remain working in,
       office buildings and other facilities
 
                                       34
<PAGE>   40
 
     - The failure of substantial numbers of our mission-critical information
       systems, including both hardware and software necessary to control
       operational facilities such as water and wastewater treatment facilities
       and distribution and collection systems
 
   
     We could face substantial claims by governments, governmental authorities
or customers, as well as loss of revenues, due to service interruptions,
violations of environmental regulations, inability to fulfill contractual
obligations, inability to account for obligations and increased expenses
associated with litigation, harm to persons or to tangible property, violation
of environmental regulations, stabilization of operations following system
failures and the execution of contingency plans. We could also experience an
inability by customers and others to pay, on a timely basis or at all,
obligations owed to us. In addition, we could face claims of damage to persons
or property as the result of improperly treated water or wastewater. Under these
circumstances, there would be a material adverse effect on revenues and
operations. However, this effect can not be quantified at this time. Also, the
cumulative effect of Year 2000 failures in the United States and internationally
could have a substantial adverse effect on the domestic and worldwide economy.
    
 
     We will continue to monitor business conditions in order to assess and
quantify any material adverse effects that may result from Year 2000 problems.
 
  Contingency Plans
 
     As part of the Enron plan, we will develop contingency plans in case we
have not satisfactorily remediated all our internal mission-critical systems and
in case outside systems are not Year 2000 ready. Our contingency plans will be
designed to minimize the disruptions or other adverse effects resulting from
Year 2000 incompatibilities with respect to our mission-critical functions and
systems and to facilitate the early identification and remediation of Year 2000
problems that first manifest themselves after January 1, 2000.
 
     Our contingency plans will include an assessment of our mission-critical
internal information technology systems and our internal operational systems
that use computer-based controls. The contingency planning will begin in 1999
and will continue as necessary. As we implement our contingency plans, we will
assess any mission-critical disruptions due to external Year 2000 failures.
These assessments will be conducted for both our U.S. and non-U.S. operations.
In assessing Year 2000 failures, we will monitor mission-critical services such
as electrical power and telecommunications services. The contingency plans will
also cover events such as failure of the delivery of chemicals for water and
wastewater treatment or events of sabotage.
 
     Our contingency plans will include the creation of response teams that will
be standing by and prepared to respond rapidly to Year 2000 problems. The
composition of these teams will vary according to the nature, importance and
location of the problem. We will also station response teams at our non-U.S.
operations as necessary.
 
  Outlook
 
     The extent and magnitude of the effects of Year 2000 on us, both before and
after January 1, 2000, are difficult to predict or quantify for a number of
reasons including:
 
     - Difficulty of locating chips embedded in computer hardware and in devices
       used in mission-critical systems such as process or flow control,
       environmental, transportation, access and communications
 
     - Difficulty in evaluating and testing outside systems connected to our
       computer, telecommunications, plant or other mission-critical systems or
       on which our mission-critical systems depend, such as electrical
       utilities or telecommunications carriers
 
     - Difficulty locating mission-critical internal software that is not Year
       2000 compatible
 
     - The possible unavailability of trained hardware and software engineers,
       technicians, and other personnel to perform remediation, validation, and
       testing of mission-critical systems
                                       35
<PAGE>   41
 
     Year 2000 costs are difficult to estimate accurately because of
unanticipated vendor delays, technical difficulties, the impact of tests of
outside systems and similar events. For example, there can be no assurance that
all outside systems that are mission-critical to us, or are mission-critical to
the Enron systems on which we depend, will be adequately remediated so that they
are Year 2000 ready by January 1, 2000. If there are Year 2000 failures that
create substantial disruptions to our business or to Enron's business, the
adverse impact on our business could be material. Moreover, the estimated costs
of implementing the Enron plan do not take into account the costs, if any, that
might result from Year 2000 failures that occur despite our implementation of
the Enron plan.

                  GOVERNMENT OUTSOURCING THROUGH PRIVATIZATION
 
     Governments around the world are increasingly outsourcing the ownership,
operation and management of their water and wastewater assets and services to
the private sector. For many projects, there is a lead-time of several years
while the government, with the help of its international financial and legal
advisors, works on the concept of privatization and gains consensus among
various interest groups. The decision to privatize is generally authorized by
legislation. Different approaches are used by various governments. Many
governments choose a public tender process to ensure that privatizations occur
at market rates. In some parts of the world, particularly Latin America, an
auction format has been used successfully. In other places, notably China,
private parties often negotiate directly with the government with no formal
invitation to bid.
 
     If a tendering process is used, rules are published. These rules generally
require some form of qualification for bidders, where parties submit financial
and operational credentials and the government accepts only qualified parties as
bidders. Qualification for bidding has heavily emphasized prior experience in
operating water and wastewater systems or individual treatment plants that are
of a size at least comparable to the system or facility being privatized or
built. The potential bidders submit extensive documentation to qualify for
bidding and often must form entities within the country through which to submit
their bids. In addition, governments often consider the financial strength of
the potential bidders and may require substantial bid bonds or letters of credit
to be provided as part of the bid.
 
COMMON FORMS OF OUTSOURCING
 
     - SALE OF WATER ASSETS. A government may incorporate a water and wastewater
       system and sell all or part of it to private parties. The water company
       is given a monopoly license to operate in a specified service territory.
       The license may be subject to revocation for non-performance or another
       breach of its terms and to renewal periodically, typically every 20 to 30
       years. For example, the United Kingdom privatized the ten regional water
       and wastewater authorities in England and Wales through public offerings
       of shares in 1989, and Berlin, Germany is in the process of selling a
       49.9% interest in its water and wastewater system.
 
     - CONCESSIONS. Short of an outright sale of water assets, a government may
       grant a private party the right to operate a water and wastewater system
       for a fixed term, retaining title to the underlying assets. The holder of
       a concession takes on the financial risks of managing the assets during
       the term of the concession, often 20 to 30 years but in some cases
       extending much longer. The concession agreement often mandates
       improvements to the water and wastewater system, sets standards of water
       quality that must be achieved and establishes a timeframe for realizing
       these objectives. At the end of the concession, control of the assets
       reverts to the government, which may renew the concession with the
       existing holder or another party. Many of the water and wastewater
       opportunities around the world take the form of concessions. See
       "Business -- The Global Water Industry -- Trend Toward Government
       Outsourcing Through Private Sector Participation."
 
   
     - CONSTRUCTION AND OPERATION OF A SINGLE ASSET. Sometimes a government will
       ask a private sector participant to construct and operate a particular
       facility that serves its water or wastewater system. Frequent examples
       are water and wastewater treatment plants, pipelines and aqueducts. Two
       typical transaction structures are a build-own-operate or
       build-own-transfer project. In both a build-own-operate and a
       build-own-transfer project, the private party builds, owns and operates
       the asset. In the case of a build-own-transfer project, the private party
       then transfers the asset back to the government after a fixed term,
       usually 15 to 25 years but often longer. The build-own-operate or
       build-own-transfer contract describes the project and its services, as
       well as the revenues the private party will receive for the services the
       asset provides.
    
 
     - LEASES. Under a lease, a government turns over control of the system for
       a fixed period but, unlike in a concession, the government retains much
       of the economic risk. In France, most municipalities use a type of lease
       called an affermage, which is also used in many former French colonies.
 
                                       37
<PAGE>   43
 
   
     - OPERATIONS AND MANAGEMENT CONTRACTS. Sometimes a government will ask a
       private party to operate its system on a day-to-day basis, but will keep
       most of the economic risk relating to the system. The term of the typical
       operations and management contract is five to ten years. These contracts
       are common in the United States. See "Business -- The Global Water
       Industry--Trend Toward Government Outsourcing Through Private Sector
       Participation -- North America."
    
 
     - OUTSOURCING PARTICULAR SERVICES. A government also may ask private
       parties to provide specific services to a government operated water or
       wastewater system. Examples of these services include billing,
       construction projects and residuals management. The service provider
       typically takes no risk for the system as a whole, only for the
       particular services it provides. See "Business -- The Global Water
       Industry -- Outsourcing Opportunities in the Municipal and Industrial
       Services Markets."
 
SELECTED AWARDED WATER AND WASTEWATER PRIVATIZATIONS
 
   
     The following is a list of selected water and wastewater privatizations in
Europe, North America, Latin America, Asia and the Pacific Rim that have been
awarded during the past several years. The majority of these privatizations have
been in the form of concessions, build-own-transfers or leases, except in North
America, where private parties have primarily entered into operations and
management contracts. Except as otherwise indicated in the notes to the
following table, the estimated size of these awarded privatizations is taken
from the October 1998 edition of Public Works Financing. The estimated size for
operations and management contracts represents aggregated fees over the term of
the contract. The estimated size for build-own-transfers represents construction
costs. The estimated size for concessions represents total project costs.

                                    BUSINESS
 
   
     Azurix is a global water company engaged in the business of acquiring,
owning, operating and managing water and wastewater assets, providing water and
wastewater related services and developing and managing water resources. Enron,
one of the world's leading integrated natural gas and electricity companies,
formed Azurix to pursue opportunities in the global water industry. The company,
now called Azurix, was incorporated as a shell company by Enron on January 29,
1998. Azurix's first significant step was to acquire Wessex, a water and
wastewater company based in southwestern England, for $2.4 billion on October 2,
1998. Wessex was recognized in December 1998 by the industry regulator as the
most efficiently operated water and wastewater company in England and Wales.
Following our acquisition of Wessex, we began implementing our global business
strategy.
    
 
   
     Our asset portfolio also includes interests in long-term water concessions
in the Province of Mendoza, Argentina and in Cancun, Mexico. In addition, on
March 25, 1999, we agreed to purchase all of the stock of Philip Utilities
Management Corporation, a water and wastewater services company in the United
States and Canada, for $107 million. The acquisition is subject to closing
conditions, including the receipt of third party and regulatory consents, and is
expected to close in the second quarter of 1999. Upon completion of the
acquisition, we will provide operations and management, engineering, residuals
management and underground infrastructure development services for municipal
water and wastewater facilities in North America. We have made each of these
investments through one or more subsidiaries, which will be our approach as we
pursue our worldwide growth strategy.
    
 
   
     On a pro forma basis, assuming the Wessex acquisition occurred on January
1, 1998, and including our investment in the Mendoza concession from the date of
our investment but excluding Cancun and Philip Utilities, we had operating
revenues of $464.2 million, EBITDA of $298.1 million and net income of $87.2
million for the year ended December 31, 1998 and total assets of $3,358.3
million as of December 31, 1998. To date, all of our operating revenues have
come from Wessex, and substantially all of our operations have been conducted by
Wessex. The following table represents the operating revenues contributed by
each of the service categories of our business from the date of inception to
December 31, 1998, although most of the contributions occurred after the date of
the Wessex acquisition:

     We are aggressively pursuing additional water and wastewater transactions
in Europe, North America, Latin America, the Middle East, Africa, Asia and the
Pacific Rim. These include many of the upcoming privatizations identified in
this prospectus as well as various privately negotiated transactions.
    
 
   
     Our experienced management team from Enron, Wessex and other water and
wastewater systems, and multinational companies provides us with the experience
necessary to compete successfully in the global water industry. We are
transferring the skills that Enron has successfully applied in developing,
financing, operating and managing the risks of energy infrastructure projects to
our water business around the world. In addition, we are applying to our water
business the operating, management and technical skills that our executives from
Wessex and other companies have successfully used in operating and managing
water and wastewater assets while providing high quality customer service. This
management team competitively positions us to identify, evaluate, acquire,
develop, finance and operate water and wastewater projects and services
worldwide.

THE GLOBAL WATER INDUSTRY
 
   
     The global water industry includes the businesses of collecting, treating,
storing and supplying drinking water, and of collecting, treating and disposing
of wastewater and wastewater by-products. Public and private water companies
serve industrial, commercial and residential customers. Azurix estimates that
the global water industry has total annual revenues of approximately $300
billion. In addition, Azurix estimates that over $600 billion will be spent on
worldwide water and wastewater infrastructure over the next decade.
    
 
   
     The ownership of water assets and the provision of water and wastewater
services around the world remains highly concentrated in the public sector,
typically at the municipal or community level. Major capital investment and
increased efficiencies in the water sector are required by the following:
    
 
   
     - Increasingly stringent standards for water quality, wastewater services
       and environmental protection
    
 
   
     - The need to provide growing urban populations with safe drinking water
       supply and wastewater treatment systems
    
 
   
     - The aging of existing water and wastewater infrastructure
    
 
   
     Governments throughout the world frequently face budgetary constraints and
often lack the technical and operational skills of private sector participants
to address these issues efficiently. As a result, governments are increasingly
turning to the private sector to address their water and wastewater
infrastructure needs.
    
 
     Industrial companies also must comply with increasingly stringent standards
for water quality, wastewater services and environmental protection. To meet the
additional expense of complying with these standards and to reduce uncertainty
in financing their operations, many industrial companies are beginning to
outsource their water supply and wastewater requirements to third parties with
the expertise to construct and operate their systems and provide services on a
more efficient and cost effective basis. The ability to manage water resources
and efficiently transport water to areas where water is scarce, including the
delivery of drinking water to growing urban centers, is becoming increasingly
important as well.
 
     As a result, we believe that significant opportunities exist for private
sector participation in the water and wastewater industry. These opportunities
include taking part in water and wastewater privatizations, providing water and
wastewater related services to municipal and industrial water markets and
developing and managing water resources.
 
  TREND TOWARD GOVERNMENT OUTSOURCING THROUGH PRIVATE SECTOR PARTICIPATION
 
     Following the trend of private sector participation in the natural gas,
electricity and telecommunication industries, governments around the world are
increasingly turning to the private sector to own, operate and manage their
water and wastewater assets and services. According to World Bank statistics,
between 1984 and 1990, developing countries awarded contracts for only eight
water and wastewater projects to private companies, amounting to a total of $297
million. According to these same statistics, by the end of 1997, the cumulative
level of private sector investment had increased to $25 billion. As of October
1998, according to Public Works Financing statistics, there were approximately
380 planned, funded or completed water and wastewater projects with private
sector participation worldwide for a total estimated cost of approximately $74
billion.
 
     The following discussion summarizes some of the water and wastewater
outsourcing arrangements that have been awarded to date and are expected to be
upcoming in various regions of the world. For a more detailed description of the
outsourcing arrangements that have been awarded to date, see "Government
Outsourcing Through Privatization."

     EUROPE. The United Kingdom has privatized large portions of its water
sector. French municipalities have long turned to the private sector to operate
their water and wastewater systems. Several other European water and wastewater
service providers are scheduled to offer major concessions or build-own-
transfer or build-own-operate projects in 1999 and 2000. We believe that the
pace of privatization may increase once these additional privatizations have
occurred in Europe and the benefits of privatization are recognized. In
addition, European Union directives are imposing higher water and wastewater
standards on member countries and are requiring significant capital investment
for compliance throughout the region. We believe that these countries will rely
on the private sector to help fund these capital requirements. The following is
a list of selected upcoming water and wastewater privatizations expected to be
awarded in Europe.

     NORTH AMERICA. In the United States, approximately 80% of the population is
currently served by approximately 24,000 government owned and operated water and
wastewater authorities. Although the U.S. market shows significant potential for
concessions or asset sales because so small a percentage of the population is
served by private water companies, few municipalities have used these
approaches. Municipalities are reluctant to give up ownership of their water and
wastewater systems and access to tax exempt financing. Thus, in the U.S. market,
governments typically enter into public/private partnerships in which private
parties make equity investments in partnership with local water and wastewater
companies or provide lower-cost outside capital sources to fund infrastructure
requirements and growth opportunities. Governments are also outsourcing the
operation of their water and wastewater assets to private parties.
    
 
     The key factors contributing to these outsourcing decisions are:
 
     - Increased regulatory and environmental requirements contained in the Safe
       Drinking Water Act and the Clean Water Act
 
     - Deteriorating water and wastewater infrastructures within the nation's
       largest urban areas
 
     - New technologies designed to improve water and wastewater solutions with
       a minimal environmental impact
 
   
     - Significant capital requirements to meet these needs, estimated by the
       U.S. Environmental Protection Agency to be approximately $275 billion for
       water and wastewater infrastructure over the next 20 years

     LATIN AMERICA. The pace of infrastructure privatizations in Latin America
has accelerated since the first electricity privatizations took place in Chile
during 1982. Since then, privatizations of electricity, natural gas and
telecommunications assets have occurred in parts of Argentina, Brazil, Chile,
Colombia, the Dominican Republic, El Salvador, Guatemala, Panama and Peru, among
other countries. To date, privatizations of water and wastewater systems have
occurred in Argentina, Brazil, Bolivia, Chile, Colombia and Mexico and are
scheduled in many other countries, including the Dominican Republic, Ecuador,
Panama and Venezuela. The following is a list of selected upcoming water and

     MIDDLE EAST AND AFRICA. Many Middle Eastern and African countries are faced
with acute water shortages. As a result, several Middle Eastern countries are
seeking private development of major transportation or treatment projects which
may include build-own-transfer projects for pipelines, canals and treatment
plants. Although privatization is not widespread in Africa, there are
exceptions. Cote d'Ivoire, while still a French colony, granted a long-term
concession to a French-owned company. A majority of the concessionaire is now
owned by public stockholders. The following is a list of selected upcoming water

  OUTSOURCING OPPORTUNITIES IN THE MUNICIPAL AND INDUSTRIAL SERVICES MARKETS
 
   
     We believe that municipal governments and industrial companies in North
America and Western Europe, in particular, will increasingly seek to outsource
the management of their water and wastewater systems to private parties with the
operating experience and capital to provide reliable services, to comply with
more stringent regulatory requirements for water quality and environmental
protection and to reduce uncertainty in financing these operations. To comply
with stricter environmental and drinking water quality standards, municipalities
will incur increased labor costs for treatment, higher monitoring and equipment
maintenance costs and increased costs of disposing of biosolids. Federal funding
grants to help municipalities meet their financial needs have declined over
time, leaving municipal wastewater authorities facing serious budgetary
challenges. Private sector outsourcing can include any combination of design,
financing, construction, ownership or operation of a facility; administrative
services such as metering, billing, collection or maintenance; and applying
process engineering technologies such as biosolids filtration, clarification,
purification, separation, drying and disposal.
    
 
     Industrial companies are also experiencing rising costs related to their
water and wastewater needs. The chemical, refining, pharmaceutical, high
technology, food and beverage, paper and pulp, steel, automobile and energy
industries have large water supply and wastewater treatment requirements. These
industries require pure water for their operations and produce effluents that
must be treated before being released into normal wastewater systems or being
discharged directly into the environment. Most industrial wastewater needs to be
pre-treated and environmental laws prohibit the direct discharge of wastewater
into the environment without a permit. Many industries treat and dispose of
their own wastewater because the relatively concentrated wastes from these
industries frequently cannot be discharged into the public sewer system and
on-site treatment is usually less expensive.
 
   
     These industrial companies must invest large amounts of capital in their
water and wastewater treatment and distribution assets. By outsourcing the
management of these assets to third parties, these companies may reduce the
uncertainty associated with expenditures required by changes in water quality
standards and environmental regulations. Obtaining landfill, storage and
incineration capacity to dispose of the residue from the wastewater treatment
process is a major component of providing industrial wastewater services, and
may involve procuring long-term capacity of specially lined or hazardous waste
landfills.
    
 
     The services to be provided to municipal and industrial customers generally
fall into three main categories:
 
   
     OPERATIONS, MANAGEMENT AND ENGINEERING. Over the past few years, large
cities and industrial companies have reduced costs by outsourcing the design,
construction, operation or maintenance of their water and wastewater assets to
private sector service providers. Many of these service providers have
consolidated and the market is much less fragmented than either the residuals
management or the underground infrastructure markets. Consequently, competition
for major contracts for the largest cities in the United States has been
significant. Although some companies have focused on providing services to small
to medium sized municipalities and large industrial firms, many of these
companies lack the financial capacity or risk management capability to purchase
water and wastewater assets from their industrial customers or to qualify on
their own as the operators and managers of their customers' facilities.
According to the May/June 1998 issue of Environmental Business Journal, the fees
associated with providing contract operations and consulting, design engineering
and maintenance services to customers in the municipal and industrial markets in
the United States are estimated to have exceeded $5.5 billion for 1997, and are
expected to continue to grow.
    
 
     RESIDUALS MANAGEMENT. Managing the biosolids that result from municipal and
industrial wastewater represents a large component of the cost of wastewater
treatment. Increasingly stringent effluent discharge standards are resulting in
a significant increase in the quantity of residuals. At the same time,
environmental regulations are limiting waste disposal options. For example,
ocean dumping of biosolids has been banned in the United States and the European
Union, increasing costs for managing residuals in these regions. In addition,
environmental regulations are requiring firms to provide beneficial reuse
solutions. Incineration, landfilling, land application and producing compost are
becoming the only available
                                       46
<PAGE>   52
 
disposal options in many countries and have inspired a number of new disposal
and reuse technologies. Certain applications can turn biosolids from waste into
a substance that can be sold as soil conditioner or that can be burned as fuel.
These technologies create a product with market value and provide an
environmentally attractive alternative to the increasingly expensive and scarce
disposal options of incineration and landfilling.
 
     Residuals management companies provide services to local and state
agencies, municipalities and private companies. Specific services include the
transportation, treatment, site monitoring, disposal and environmental
regulatory compliance services associated with biosolids and wastewater
disposal. These companies provide a variety of residuals management options to
prospective customers who seek alternative methods of biosolid treatment. Not
all methods can be profitably and practically applied in all geographic areas
due to the specific nature of the terrain and agriculture in the region and the
local biosolid content.
 
   
     We estimate that 55% of biosolids produced in the United States are
recycled, and we anticipate that recycling of biosolids will continue to grow
over the next decade. As recycled uses of biosolids continue to increase, we
believe that larger and more sophisticated companies will have opportunities to
create value through economies of scale and scope by providing new solutions to
these problems.
    
 
   
     UNDERGROUND INFRASTRUCTURE REMEDIATION AND DEVELOPMENT. We estimate that
nearly 60% of the assets in the water and wastewater industry consist of
underground distribution networks and that over half of the approximately $275
billion of capital that the EPA estimates will be spent in the United States
during the next 20 years will be spent on repairing, replacing and developing
the nation's underground water and wastewater infrastructure.
    
 
     Much of the cost associated with the repair, replacement and development of
underground infrastructure is attributable to the lost revenues resulting from
the disruption of service associated with open cut excavation. During the past
decade, advances in the oil and natural gas industry have been used in the water
industry, enabling the repair of underground infrastructure without open cut
excavation. Trenchless technologies such as horizontal drilling, tunneling,
grouting and pipe lining enable the repair and replacement of water
infrastructure with a fraction of the disruption associated with traditional
open cut excavation.
 
   
     Currently, small local civil engineering firms and contractors perform most
of the trenchless underground infrastructure work. As the size of these projects
grows and the capital requirements and sophistication of these newer
technologies increase, we believe larger, better capitalized and more
sophisticated firms who hold experience in the oil and gas industry will have a
competitive advantage in obtaining this business. We expect that the underground
water and wastewater infrastructure market for the municipal market in the
United States will grow during the next decade.
    
 
  WATER RESOURCE DEVELOPMENT AND MANAGEMENT
 
     We believe that the management of aquifers and other water resources and
the storage and transportation of water offer important opportunities for
business development. In many regions of the world, such as parts of North and
South America, the Middle East and many island nations, lack of abundant water
resources is a critical issue. Governments, which historically have been
responsible for developing and managing water resources, are now seeking private
sector assistance to address their water resource issues due to the operational,
technical and financial expertise required to operate, build and fund these
capital intensive projects.
 
     In many countries, including the United States and China, water consumption
is mainly driven by patterns of population movements and industrial and urban
development. In parts of the United States, increases in water demand resulting
from large population shifts to the sunbelt, multi-year droughts and
irrigation-intensive agriculture have resulted in consumption that exceeds the
natural rate of replenishment. This has led to large scale diversions of surface
water through dams and reservoirs and to diminished groundwater supply. In
China, rapid economic growth in the Southern provinces (primarily the Guandong
 
                                       47
<PAGE>   53
 
and Shanghai areas) has significantly increased demand for water.
Drinking-quality water now used in agriculture may need to be diverted to
population centers.
 
     In light of these factors, industry participants are focusing new efforts
on means of extracting, managing, storing and transporting water resources as
efficiently as possible. The large amount of capital required and the inability
of local governments to fund these needs compound the difficulties in developing
and managing water resources. Transporting water over long distances to urban
areas requires canals, aqueducts, underground pipelines and/or pumping stations.
These are typically large infrastructure projects requiring significant
development, construction, operational and financial expertise.
 
  COMPETITION
 
     Participants in the global water market face significant challenges,
including qualifying for the bidding process, obtaining and demonstrating
operating experience and management depth, accessing capital, obtaining and
demonstrating expertise in managing international infrastructure projects,
identifying and evaluating transactions and assessing and mitigating risks,
especially operational, political and regulatory risks. As a result, only a
small number of companies currently compete globally in the water and wastewater
privatization market.
 
   
     Two French companies, Suez Lyonnaise des Eaux and Compagnie Generale des
Eaux, a subsidiary of Vivendi, currently are recognized as the leading
competitors in the international water and wastewater market. According to Suez
Lyonnaise des Eaux, it serves an aggregate population of approximately 77
million for water and 52 million for wastewater. According to Vivendi, Compagnie
Generale des Eaux serves an aggregate population of approximately 80 million for
water and 30 million for wastewater. These two companies are significantly
larger than the next group of international competitors, the largest of which
serves an aggregate population of approximately 31 million. These smaller
competitors include privatized water and wastewater companies from the United
Kingdom and some smaller French and Spanish companies. We are a new competitor
in the international water and wastewater market, and we currently serve an
aggregate population of approximately four million. Some construction companies
also bid on water and wastewater projects, more often on build-own-transfer
projects than on concessions.
    
 
   
     In the United States, the water and wastewater industry is highly
fragmented, with over 55,000 public and private water entities serving
approximately 90% of the nation's population. Of this number, nearly half are
investor owned and the rest are publicly owned, generally by local
municipalities. Most of these entities serve only a single community or region.
There are only 17 publicly traded water and wastewater companies among the
nation's approximately 30,000 investor owned companies, and only three of these
companies have a market capitalization of over $500 million. Several of these
publicly traded companies have become active consolidators by acquiring the
small private and public investor owned utilities that operate in markets
contiguous to or near their own. Of the three largest consolidators, none has
more than a 3% market share in the United States, and these three combined serve
only 6% of the nation's customers. In addition, several electric utilities have
begun to acquire municipally owned water distribution companies in the United
States. Many companies compete in the United States for municipal service
contracts and industrial outsourcing opportunities, including subsidiaries of
the French and U.K. water companies.
    
 
   
     In the United Kingdom, 10 water and wastewater authorities in England and
Wales were privatized in 1989 to form 10 water and wastewater companies
operating in geographically discreet regions. Wessex has a virtual monopoly over
water supply and wastewater services in its licensed region, with the exception
of the cities of Bristol and Bournemouth and a small area of rural Wiltshire,
where three companies provide water and Wessex provides wastewater services.
Other companies may apply to the industry regulator for a so-called "inset
appointment" to serve particular areas within Wessex's or any other licensee's
service area. Historically, very few inset appointments have been granted in
England and Wales. Wessex does have one inset appointment within its territory
resulting from the privatization of water supply activities formerly provided by
the Ministry of Defence. Wessex chose not to pursue this project because of
unacceptable contract terms. The Chancellor of the Exchequer announced in March
1999 that the Government intends
    
 
                                       48
<PAGE>   54
 
   
to study ways to increase competition in the United Kingdom's water sector. We
cannot predict what changes, if any, the Government will adopt to promote
competition. See "-- Existing Azurix Assets -- Wessex."
    
 
OUR COMPETITIVE STRENGTHS
 
   
     We have several competitive strengths that should enable us to compete
successfully in the global water industry.
    
 
   
  EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAMS
    
 
   
     Although our company was only recently formed, we have a group of
experienced managers from long-established companies, including Enron, other
multinational companies, Wessex and other water and wastewater companies. Our
management team has extensive experience in both the development and operation
of infrastructure projects worldwide and years of experience in managing water
and wastewater companies primarily in the United Kingdom and also in the United
States. Many of our executives were actively involved in developing and managing
natural gas and power projects for Enron in the United States and around the
world. Enron is one of the world's leading integrated natural gas and
electricity companies with a market capitalization of approximately $28 billion.
Rebecca Mark, chairman and chief executive officer of Azurix and a vice chairman
of Enron, leads the Azurix team in implementing its global water strategy.
During her tenure at Enron, Ms. Mark was responsible for the successful
development of natural gas and power projects worldwide. Beginning with Enron's
first international power project in Teesside, England in 1989, Ms. Mark led the
team that developed gas and power projects around the world with total estimated
capital costs exceeding $10 billion.
    
 
   
     Four other senior executives give the management team collectively 80 years
of experience in managing water companies in the United Kingdom and the United
States. In addition, our management team has infrastructure development
experience in Europe, North America, Latin America, the Middle East, Africa,
Asia and the Pacific Rim. Our senior executives are complemented by a group of
experienced business developers who identify opportunities in the global water
industry. We believe that the collective experience of our management and
business development teams will enable us to compete successfully for public
tenders. Since our formation, we have qualified for bidding on numerous pending
privatizations in Europe, Latin America and the Middle East. Of those
privatizations in which we have actively participated, only one award has been
made. In this bid for the concession in Valparaiso, Chile, we were second to the
winning bidder. We are currently one of the three finalists for the partial
privatization of the Berlin, Germany water and wastewater system. In addition,
we have identified and negotiated successfully two private transactions.
    
 
   
     Our management team will build upon its extensive experience and knowledge
from Enron, Wessex, other water and wastewater systems and other multinational
companies to provide us with the necessary skills to compete effectively in the
global water industry. Although most of our management team's experience in the
water and wastewater industry has been primarily in the United Kingdom and the
United States, we believe that our management team has the requisite operating
experience and management depth to identify and evaluate potential water and
wastewater projects, to qualify for bidding on projects in many countries
throughout the world, to access capital and to develop and manage projects. Our
management team has the ability to:
    
 
     - Mobilize the array of resources needed to enter competitive bids for
       concessions tendered in privatizations
 
     - Develop projects requiring construction of new facilities in developed
       and emerging countries
 
     - Meet the challenges of "fast-track" projects to be brought on-line within
       12 to 18 months
 
     - Execute major acquisitions
 
     - Operate regulated companies, including managing their tariff and other
       regulatory issues
 
                                       49
<PAGE>   55
 
     - Apply innovative financing and risk-management strategies in markets
       worldwide
 
     We expect to apply many of the same disciplined techniques to analyze
projects and mitigate risks that Enron has developed in its own worldwide
activities. In identifying and quantifying the risks and value of a transaction,
these processes require an analysis of the engineering, operational, regulatory,
financial, economic, structural, legal, insurance, tax and accounting
implications of the transaction. These analytical skills will competitively
position us in the identification, evaluation, development, financing and
acquisition of worldwide water and wastewater projects and in the provision of
associated services.
 
  WESSEX OPERATING EXPERIENCE AND TECHNICAL EXPERTISE
 
   
     From Wessex, we have obtained the operating experience, research skills and
technical expertise necessary to evaluate potential water projects, to qualify
for bidding on water projects in many countries throughout the world, to build
transition and operating teams for new acquisitions and to manage existing and
new water assets. Wessex supplies approximately 400 million liters of water per
day to a population of approximately 1.1 million and treats on average 484
million liters of wastewater per day from a population of approximately 2.5
million. In December 1998, the water industry regulator for England and Wales
rated Wessex the most efficiently operated privatized water and wastewater
company. Wessex's management team has been in place since the privatization of
the U.K. water industry in 1989. For a discussion of Wessex, see "-- Existing
Azurix Assets -- Wessex."
    
 
     Wessex uses advanced treatment techniques, increased automation of
operations and services and state-of-the-art control and monitoring systems that
are designed to ensure consistently high standards at low cost. Since its
privatization, Wessex has improved levels of quality and standards of service,
providing reliable water supplies without requiring any water usage
restrictions. It has delivered this high quality service while reducing
operating costs and delivering capital improvements below budgeted amounts. In
addition, Wessex has developed extensive performance data that will be used for
benchmarking purposes in Azurix operations around the world.
 
   
     We will also benefit from Wessex's experience with meeting mandated capital
expenditure targets through the use of standard designs, the cost-effective
management of major projects and in-house process and concept design. In
addition, the use of local contractors and detail designers as well as
appropriate technology and efficient procurement are key factors in capital
expenditure management that have benefited Wessex in the past. During the 1990s,
Wessex successfully managed a $2.0 billion investment program on time and below
the price allowed by regulation. Current regulatory reports show Wessex as
having among the lowest unit costs and achieving the second highest return on
capital in the U.K. water and wastewater industry.
    
 
     We will apply Wessex's operational and capital expenditure management
skills in our global water business. We believe many of these skills are
transferable to other water and wastewater assets or services we will acquire or
manage.
 
  REGULATORY AND GOVERNMENT AFFAIRS EXPERTISE
 
   
     Our management team has extensive experience in working with regulators and
other governmental agencies. For example, our executives include:
    
 
   
     - The executive and regulatory team from Wessex, which has operated for 10
       years in the U.K.'s privatized water sector
    
 
   
     - The former general manager of the Metropolitan Water District of Southern
       California, which through its 27 member public agencies provides almost
       60% of the water used by nearly 16 million people living in portions of
       Los Angeles and southern California
    
 
   
     - A director of the Azurix regulatory team, who has 25 years of regulatory
       experience in electricity, gas and water, both in the United States and
       internationally
    
 
                                       50
<PAGE>   56
 
   
     - Executives and lawyers who have worked on private projects and
       distribution systems in the gas and electric sectors in Argentina,
       Brazil, China, Colombia, Croatia, Germany, India, Italy, Malaysia, the
       Philippines, Poland, the United Kingdom and the United States, among
       other countries
    
 
   
These members of our management team have extensive government affairs
experience and have often been involved in building relationships with local and
national governments and advising these governments on how to structure their
privatization process and regulatory regime to encourage foreign investment. In
some cases, they have direct experience in the countries and even the regions or
municipalities where we will pursue projects and operate assets, sometimes
working with the same governmental officials who may make decisions regarding
water and wastewater privatizations.
    
 
   
     As governments around the world turn to the private sector to fill their
water needs, they will draw on examples of successful privatizations in the
water sector elsewhere and, if applicable, in gas and electric sectors in their
own country. For example, the United Kingdom's privatizations of its electric
and gas sectors already has served as a model for many countries' privatizations
of those sectors, specifically, Argentina, Brazil, Chile and Colombia. We
believe governments will look to the U.K. model in water as well, and through
Wessex we are very familiar with that regime. For example, the recent water
privatization in Chile follows a national regulatory regime like the United
Kingdom, which adheres to the principles of incentive-based regulations.
Although the methods of calculating rates of return are slightly different, the
core principles remain the same. As another example, highly successful
build-own-transfer projects and privatizations of gas and electric distribution
networks have occurred in Argentina, Brazil, China, Colombia, Germany, Eastern
Europe, India and the Philippines. As those countries look for precedents in
water and wastewater, they will turn to many of the projects and systems on
which our executives previously have worked.
    
 
   
     Although we believe that the regulatory and government affairs expertise
demonstrated by our management team is transferable to water and wastewater
privatizations, there are some differences between the sectors. Because water is
an essential good affected by health, safety and environmental issues,
regulation of water is more influenced by socioeconomic and welfare pressures
than electricity and gas regulation. In addition, water and wastewater utilities
are typically vertically integrated natural monopolies, often owned by a public
entity, and subject to greater regulation than electricity and gas utilities
which are more often privately held and subject to greater competition. Finally,
water and wastewater businesses are more often regulated at a local or regional
level as compared to national regulation than electricity and gas.
    
 
   
     Despite these differences, we believe that the experience of our management
team in the fundamental aspects of regulation and privatization is transferable
to water and wastewater privatizations.
    
 
  FINANCING EXPERTISE
 
   
     Access to capital is essential in the global water business due to its
significant financial requirements. We plan to employ sophisticated financing
techniques and instruments similar to those successfully used by members of our
management team in other infrastructure-intensive businesses. Our executives
have experience in raising large amounts of capital through the capital markets
and through innovative financing structures. In addition, the team brings
experience in attracting private equity capital and using this capital to
enhance the borrowing capacity of our projects and achieve greater returns for
equity holders. In financing a project through debt, we may enhance returns by
placing a portion of the debt at the level of the holding company created to own
a particular concession or facility. As our portfolio grows and matures, we also
intend to enhance our equity returns and reduce overall risk exposure through
opportunistic sales of all or a portion of individual assets or investments. In
addition, our management has experience in applying financing techniques
familiar to the domestic infrastructure market, such as leveraged leases, to
international markets.
    
 
     Many of our executives have developed extensive contacts and experience in
the global financial market. We intend to work in partnership with multilateral
agencies such as the World Bank, International
 
                                       51
<PAGE>   57
 
Finance Corporation, the Inter-American Development Bank, the European Bank for
Reconstruction and Development and the Overseas Private Investment Corporation.
 
     We intend to apply our financial expertise and skills to the global water
industry to lower the cost of capital for our projects and acquisitions.
 
OUR BUSINESS STRATEGY
 
     Our business strategy is focused on three complementary areas in the global
water industry:
 
     - Acquiring, owning, operating and managing water and wastewater assets
 
     - Providing water and wastewater related services, including operations,
       management and engineering, residuals management, and underground
       infrastructure development and remediation services
 
     - Developing and managing water resources
 
     Our participation in each of these areas should allow us to satisfy the
needs of a full spectrum of water and wastewater customers. The particular
characteristics of each market as well as customer needs that vary by region and
market will drive our approach to developing these business lines and providing
creative solutions to water and wastewater needs in those markets.
 
  ACQUIRING, OWNING, OPERATING AND MANAGING WATER AND WASTEWATER ASSETS
 
     ACQUIRING WATER AND WASTEWATER ASSETS. We intend to build a diversified
portfolio of water and wastewater assets, including both established businesses
with stable returns and concessions and projects in emerging markets with
significant development requirements and potential for growth and enhanced
returns. We also intend to consider acquisitions of privately owned water and
wastewater assets throughout the world with predictable contractual or regulated
revenue streams that will complement our portfolio and strengthen our
competitive position in the global water industry.
 
   
     We intend to acquire water and wastewater assets through participation in
public tenders and privately negotiated transactions throughout the world,
including Europe, North America, Latin America, the Middle East, Africa, Asia
and the Pacific Rim. As the trend toward privatization continues, we expect new
opportunities to materialize around the world. See "-- The Global Water
Industry -- Trend Toward Government Outsourcing Through Private Sector
Privatization."
    
 
   
     We intend to target opportunities where there is potential for increased
returns and where we can draw on the experience of our management team in
regulatory and rate case analysis, political risk assessment, country-specific
project development and water infrastructure operation. In some instances, we
may join with other parties, including local entities, in acquiring or bidding
on assets. We will evaluate potential projects and acquisitions based on a
variety of financial, strategic, regulatory and operational factors and utilize
our sophisticated financial, legal and tax analysis capabilities to determine
the appropriate acquisition and ownership structure designed to minimize risks.
From inception, the analysis of potential acquisitions will be staffed by our
employees with assistance from affiliated companies and external experts as
needed. We expect to work with Enron's extensive network of offices and
businesses around the world in identifying and pursuing potential water and
wastewater and service opportunities.
    
 
     We carefully evaluate each project to assess its value. First, we conduct a
due diligence review, identifying and quantifying the specific risks of the
transaction. We then measure and manage these risks by preparing a detailed
financial projection containing elements that we believe may affect the project
materially throughout its economic life. We forecast inflation rates and, where
applicable, changes in foreign exchange rates. We test projections for debt
capacity, terms and rates along with an evaluation of local and world financial
markets to assure the accuracy of our assumptions relating to capital costs. We
quantify all other assumptions from the internal and external team of experts to
forecast costs and revenues in the transaction. We then run multiple
simulations, testing for various sensitivities and producing an analysis of the
return on capital, adjusted for the risk of the specific project.
 
                                       52
<PAGE>   58
 
   
     Azurix Europe is a party to various credit facilities and loan agreements
with restrictive covenants. We do not believe that these existing credit
facilities will impair our ability to carry out our business strategy. Although
the existing senior credit facility and the new senior credit facility both
place restrictions on Azurix Europe's ability to engage in mergers, acquisitions
or asset sales, they do not place any such restrictions on Azurix. We are
currently refinancing the existing senior credit facility and expect to replace
it in May 1999 with a new senior credit facility that will specifically permit
Azurix Europe to lend funds to other subsidiaries or affiliates of Azurix for
the purpose of making investments in, or acquisitions of, water or wastewater
related assets or businesses around the world. In addition, neither the new
credit facility nor the other existing credit facilities and loan agreements
prohibit Azurix from engaging in mergers, acquisitions or asset sales. In
addition, they do not hinder Azurix's ability to incur indebtedness at the
Azurix level or incur project specific indebtedness with the borrowing capacity
generated from the cash flows of future acquisitions. See "Description of
Indebtedness."
    
 
   
     The business opportunities agreement that we will enter into with Enron
will limit the businesses that we may pursue. The agreement will allow us, only
with Enron's consent, to engage in businesses outside the water and wastewater
industries, or in which water and wastewater is not expected to generate the
major component of value. This could limit our ability to pursue potentially
profitable ventures that are not clearly in the water and wastewater sector,
even though those opportunities come to our attention on account of our
activities in water and wastewater. See "Certain Transactions -- Agreement
Regarding Business Opportunities and Related Matters."
    
 
     OWNING, OPERATING AND MANAGING WATER AND WASTEWATER ASSETS. To ensure a
smooth transition and to introduce more efficient working practices in the
concessions and businesses we acquire and the start-up of new facilities we
construct, we will send specialist transition teams of experienced staff with a
full range of skills. Existing employees of Wessex, including over 300
engineers, scientists and other specialists, will be made available to operate
our assets, especially during critical periods of takeover or start-up. We
intend to use the systems and working methods that Wessex successfully employed
to increase productivity and reduce costs.
 
     Following an acquisition of a water or wastewater asset, we intend to:
 
   
     - Enhance income by extending services and increasing operating revenues
    
 
     - Reduce operating costs and capital expenditures through better management
       and procurement strategy
 
     - Increase efficiency through the use of technology and management
       information systems
 
     - Apply innovative financing techniques and sound financial and risk
       management techniques
 
   
     Revenue Enhancements. Water and wastewater systems offer many opportunities
to increase operating revenues. For example, we might expand the number of
customers connected, while more efficiently managing the capital expenditures
required to serve them. New customers could result from inherent population
growth or migration to urban areas in the service territory. Another operating
revenue enhancement is the effective use of water meters. Many water systems
around the world do not use water meters. By installing meters where
appropriate, we could track water demand more effectively and allocate water
resources and service teams more efficiently. Where permitted, we will shorten
billing periods, which expedites receipt of operating revenues and increases
their collectibility. We will also apply more sophisticated billing technology
to assure that customers are being billed and delinquent accounts are being
pursued. Through improved service and better community relations, we expect to
reduce uncollectibles.
    
 
     Cost Containment Strategies. Our experience at Wessex helps us identify
ways to control expenditures in operating our water and wastewater systems and
facilities worldwide. These techniques are highly transferable from one location
to another. In particular, we intend to:
 
     - Use sophisticated tracking and monitoring equipment to reduce water
       losses from leakage and theft
 
     - Reorganize the workforce to improve productivity
                                       53
<PAGE>   59
 
     - Procure equipment, chemicals and ancillary services more cost effectively
 
     - Shorten construction periods
 
     We expect that these value-added strategies will allow us to realize
attractive returns on our global water industry investments. Whether responding
to a tender or negotiating a contract directly, we expect to combine our
experience from the concessions and projects we already have with our financing
skills to offer a highly competitive price and, once we acquire an asset, to
serve our customers efficiently and effectively.
 
  PROVIDING MUNICIPAL AND INDUSTRIAL SERVICES
 
     We intend to provide a broad range of cost-effective services to owners of
water and wastewater systems in governmental, commercial, industrial and
agricultural markets around the world through innovative technological,
environmental and financial solutions.
 
     Our water related services business will target municipal and industrial
customers, initially in the United States and Europe, that are seeking to
outsource the management of their systems. These customers generally desire a
service provider with the operating experience and capital to provide reliable
water supply and wastewater treatment services and the ability to comply with
more stringent regulatory requirements for water quality and environmental
protection. The current market has few operators that manage a large number of
diverse assets and thus have the skills to compete effectively. By consolidating
contracts for operation and management of treatment facilities and management of
biosolids disposal or reuse through acquisition and growth, we can achieve
economies of scale and operational efficiencies in this business that will allow
us to compete more effectively.
 
   
     Furthermore, by offering operations, management and engineering, residuals
management and underground infrastructure remediation and development services,
we believe that we will position ourselves to capitalize on privatizations as
they occur. Providing a full range of services represents our primary method for
consolidating municipal outsourcing activities, promotes access to a full range
of governmental clients and allows municipalities to explore all their options
from outsourcing services to full privatization of their systems. Working with
municipal clients will also allow us to understand local markets and identify

  DEVELOPING AND MANAGING WATER RESOURCES
 
   
     We believe the growing demand for drinking water has generated a need for
better management of water resources. We believe that there are significant
capital, technical and operational needs for this area of the water industry and
that governments are increasingly turning to the private sector to manage and
meet these needs. Wessex has recently commenced a trial of aquifer storage and
recovery, which involves injecting drinking water into deep aquifers that act as
natural underground reservoirs. Water put into the aquifer at times of low
demand can be stored for months or years, to be used when demand is high. In
addition, we are pursuing build-own-transfer projects for long-distance
pipelines, aqueducts and reservoirs in the Middle East and other projects to
extract water in Latin America. We intend to pursue opportunities in water
resource development and management as they arise.

  WESSEX
 
   
     Wessex's principal business is providing water supply and wastewater
services in southwestern England through Wessex Water Services Ltd., a wholly
owned subsidiary. In December 1998, the Office of Water Services, the industry
regulator for England and Wales commonly called Ofwat, published its assessment
of relative operating efficiency, which showed Wessex as the most efficiently
operated water and wastewater company under its supervision. Ofwat also has
recognized Wessex for providing among the highest overall standards of service
of water and wastewater companies in the industry. Independent research shows
that over 90% of Wessex's customers consistently rate its service as "excellent"
or "good." During the 1990s, Wessex successfully managed a $2 billion investment
program on time and below the price allowed by regulation. Wessex's other
principal subsidiary is SC Technology, which conducts business as Swiss Combi
and designs, sells and operates biosolid drying plants.
    
 
     Much of Wessex's success in delivering high standards efficiently is due to
the investment in and application of the latest technology. Sophisticated
control and planning systems have largely eliminated the need for Wessex's 2,500
installations to be permanently manned. Instead, water supply and wastewater
treatment collection and distribution systems can all be monitored from one
central base. Regular maintenance and response to customer requests or
emergencies are handled through an integrated planning and management system
that ensures rapid response in the most efficient manner.
 
   
     WESSEX WATER SERVICES. Through Wessex Water Services, Wessex provides water
supply and wastewater services in southwestern England. Wessex has a virtual
monopoly over water supply and wastewater services in its region, with the
exception of the cities of Bristol and Bournemouth and a small area of rural
Wiltshire, where three companies provide only water and Wessex provides
wastewater services.
    
 
     The Wessex region covers approximately 10,000 square kilometers and is
predominantly rural. There are two major urban areas in the region, with Bristol
and Bath in the north and Bournemouth and Poole in the south. The largest town
for which Wessex provides water is Poole with a population of approximately
140,000, and the largest town for which Wessex provides wastewater services is
Bristol, with a population of approximately 400,000 (approximately 800,000
including the surrounding area). The region's economy, which is one of the
fastest growing in the United Kingdom, is based on agriculture, financial
services, aerospace, defense establishments and specialist manufacturing.
 
     Water Supply Services. Wessex supplies approximately 400 million liters of
water per day to a population of approximately 1.1 million using its water
infrastructure. The system includes approximately 138 water sources, 128 water
treatment plants, 320 pumping stations, 360 storage reservoirs and 11,000
kilometers of water mains. Wessex serves approximately 500,000 domestic and
commercial locations. Wessex's customer base is approximately 56% residential
and 44% commercial by volume of supply.
 
     Wessex withdraws 78% of its water from underground sources and the
remainder from reservoirs (19%) and rivers (3%). Wessex has a comprehensive
network of storage reservoirs (interlinked by a regional grid), which facilitate
water management during periods of low rainfall. As a result of its strong water
resources, internal grid network and water management, Wessex has not enforced
any restrictions on water usage in the past 22 years. Ofwat has ranked Wessex as
having fewer than average unplanned interruptions to water supply.
 
     Wessex is strengthening its water resources through reductions in leakage
and trials in the use of aquifer storage and recovery. Although Wessex has
reduced leakage by 20% since 1993, its leakage rates remain above average for
the U.K. industry. Ofwat sets mandatory targets to reduce leakage from both
company and customer pipes. These targets are reviewed annually and failure to
meet the targets could result in enforcement action. Wessex intends to reduce
leakage by optimizing pressure in its pipes, improving its response time for
repairing leaks and replacing pipes and joints.
 
     The flow in some rivers in Wessex's region is being affected by water being
withdrawn from underground aquifers by Wessex. This problem resulted from the
granting of water withdrawal rights to Wessex's predecessors prior to
privatization. Wessex has taken measures to reduce withdrawals of water
                                       55
<PAGE>   61
 
and has given a commitment, subject to available funding, to eliminate low river
flows caused by withdrawals of water by 2010. Wessex may need to develop
additional water resources.
 
     Wessex has invested approximately $589 million in capital projects related
to improvements in its water infrastructure since privatization in 1989, of
which approximately $430 million has been invested since 1993. Wessex's water
supply network continues to require further investment.
 
     Wessex takes an integrated approach to water quality, based on effective
control and monitoring of treatment and distribution systems. All water
treatment works have continuous automated operation and quality monitors. Wessex
also monitors water quality through a program of regular sampling and analysis.
During the year ended December 31, 1997, Wessex tested approximately 160,000
drinking water samples and achieved 99.9% compliance with the strict United
Kingdom and European Union standards. Ofwat has ranked Wessex as above average
for the provision of water supplies overall.
 
   
     Wastewater Services. Wessex treats on average 484 million liters of
wastewater per day from a population of approximately 2.5 million through its
infrastructure of approximately 360 wastewater treatment plants, 1,300 pumping
stations and 15,000 kilometers of sewers. Residential customers account for
approximately 76% of wastewater revenues and commercial customers account for
24%.
    
 
   
     Wastewater is collected in the wastewater system and pumped or gravitated
to wastewater treatment plants where the wastewater passes through processes
designed to remove biosolids and purify the wastewater. Following further
processes, Wessex disposes of 83% of its biosolids to agricultural land, uses
12% in landscaping and land reclamation work and disposes of 5% in landfills.
Approximately 20% of biosolids are subjected to an advanced heated drying
treatment at Wessex's major wastewater treatment facility at Avonmouth, near
Bristol. Wessex is currently installing similar drying facilities, referred to
as biodriers, at Bournemouth and Weston-super-Mare. A second plant is also
planned for construction in 1999 at Avonmouth.
    
 
   
     Wessex has invested approximately $1.1 billion in capital projects related
to improvements in its wastewater infrastructure since privatization, of which
approximately $785 million has been invested since 1993. Wessex has been
upgrading many of its wastewater treatment plants to comply with European Union
legislation. At some of its treatment facilities, Wessex has introduced advanced
filtering technology using membranes, ultraviolet disinfection and fully
enclosed underground plants in connection with the treatment of wastewater.
Wessex's new wastewater treatment plant at Porlock is the largest operational
plant in Europe to use membrane filtering technology to produce wastewater which
is virtually bacteria and virus free. Wessex is building a similar system at
Swanage in Dorset.
    
 
     Wessex's wastewater treatment plants perform well above industry standards.
During the year ended March 31, 1998, Wessex's wastewater treatment plants were
in substantial compliance with applicable discharge standards and 99% of these
plants were in 100% compliance with applicable discharge standards. Wessex is
committed to providing full treatment for all continuous coastal discharges
which impact on recreational waters. Full compliance with European Union bathing
water quality standards in the Wessex region during the period from April to
September 1998 was 91%, and the instances of noncompliance were due primarily to
agricultural runoff and industrial discharges, not Wessex's treatment
operations.
 
     Properties. Wessex manages over 2,500 installations. These include
approximately 138 water sources, 128 water treatment plants, 320 clean water
pumping stations, 360 storage reservoirs, 1,300 wastewater pumping stations and
361 wastewater treatment plants. The following is a list of the five largest
water treatment plants operated by Wessex:

     Customer Charges. Ofwat sets limits on the rates Wessex may charge for its
regulated water supply and wastewater treatment businesses, including the extent
of annual rate increases. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Outlook."
 
   
     Charges for water supply and wastewater services are calculated separately
based on the average costs of providing each service for each class of
customers. Currently, approximately 82% of household bills are calculated in
part on the basis of the ratable value of the property, a valuation which was
used by local governments to set municipal charges until April 1, 1990, rather
than their usage. The remaining 18% of household customers pay based on metered
water usage. Where a customer receives a metered water supply, wastewater
services charges are based on the volume of water supplied. Wessex offers free
meter installation service to all its customers and, as a result, the level of
metering in Wessex's territory is above the industry average in the United
Kingdom. New properties will be subject to metering.
    
 
   
     Charges are generally set on a standard tariff basis. Charges for bulk
supplies of water are usually determined on an individual basis, as are charges
for some larger commercial water supplies and some industrial wastewater. The
charging basis for bulk supplies in some cases provides for annual recalculation
by reference to the expenditure associated with the supply. Wastewater from
industrial users is normally charged on a formula basis taking account of the
volume of wastewater, its strength and costs of removal and treatment.
    
 
   
     In November 1998, following public consultation in April, the U.K.
Government announced new legislation to regulate water charging in England and
Wales. The proposed legislation is currently before the U.K. Parliament and
would grant domestic customers the right:
    
 
   
     - To resist water metering in their current homes where they are not using
       water for non-essential purposes
    
 
   
     - To have a free meter installed if they wish to have one, where this is
       practicable
    
 
   
     - Where they have taken up the right to have a free meter installed, to
       revert to an unmetered basis of charging within 12 months if they so
       choose
    
 
   
     In addition, the proposed legislation would enable the government to
protect vulnerable customers with high essential water use, who live in homes
with meters, from higher than average water bills.
    
 
     A review of the customer charges of Wessex is in process and new price
limits will apply from April 1, 2000. See "Risk Factors," "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Outlook" and "Regulatory Matters."
 
   
     Competition. Despite an absence of regulatory restrictions on entry into
the U.K. water industry, 98% population coverage and high infrastructure costs
deter potential new entrants. There is some limited direct competition in the
industrial market. For example, other companies may be granted the right through
"inset appointments" to supply water and wastewater services to Wessex's
customers using in excess of 250 megaliters of water per year. Inset
appointments may also be granted for "greenfield sites," which are areas
previously not served by existing companies, or where an incumbent water company
consents to change its boundary to allow part of its area to be transferred to
another company or potential company. Wessex does have one inset appointment
within its territory resulting from the privatization of
    
 
                                       57
<PAGE>   63
 
   
water supply activities formerly provided by the Ministry of Defence. Wessex
chose not to pursue this project because of unacceptable contract terms.
    
 
     SC TECHNOLOGY. In 1996, Wessex acquired SC Technology, which does business
under the name of Swiss Combi. Based in Switzerland, SC Technology is one of the
leading biosolid drying companies in the world. SC Technology designs, sells and
operates environmentally sound biosolid drying processes and markets recycled
biosolids for agriculture and land reclamation. SC Technology currently has
approximately 40 plants completed or under construction, located in more than
ten countries, primarily in Western Europe.
 
   
     Volumes of biosolids are increasing worldwide. Historically, these
biosolids were supplied to farmers or disposed of at sea. Wessex believes that
the ban imposed on disposal of biosolids at sea, together with concerns from
food retailers about the recycling of untreated biosolids over agricultural land
and air pollution problems resulting from the incineration of biosolids, make
the biosolid drying process an attractive method of biosolid disposal for the
future. The Swiss Combi process uses a contained drying system to produce
pasteurized dried granules which are odor free and easy to handle and transport.
The granules, known as biogran, have a much lower bacterial count than digested
biosolids and can be safely sold as a soil conditioner. They also may be sold as
fuel.
    
 
  MENDOZA, ARGENTINA
 
   
     In May 1998, Enron, in a consortium co-led by SAUR, a French water company,
successfully bid to acquire a controlling interest in Obras Sanitarias Mendoza
S.A., a privatized company that holds a 95-year exclusive concession to provide
water and wastewater services to the majority of the Province of Mendoza,
Argentina. Enron has contributed to Azurix its 32.1% interest in Obras
Sanitarias Mendoza, the concession holder. SAUR also owns a 32.1% interest in
the concession holder, local private investors own a 3.3% interest, Italgas owns
a 2.5% interest, employees own a 10.0% interest and the Province of Mendoza owns
the remaining 20.0%. Obras Sanitarias Mendoza is currently operated by SAUR
under an operations agreement and is governed by a five-member board of
directors, two of which have been appointed by Azurix.
    
 
   
     The concession is located in the desert bordering Chile at the base of the
Andes mountains. Its service territory covers six municipalities. The Mendoza
area has a strong economy, and is one of Argentina's fastest growing provinces.
Per capita revenue is among the highest in Argentina due to the petroleum and
mining industry activity in the area, and per capita water usage is among the
highest in the hemisphere.
    
 
   
     The concession holder is charged with operating, maintaining and upgrading
its ten drinking water plants, 17 wastewater treatment plants as well as
associated distribution and collection networks to Mendoza. Obras Sanitarias
Mendoza serves over one million water customers and has 285,000 water
connections. Obras Sanitarias Mendoza provides wastewater services to 883,000
people and has 210,000 wastewater connections. The concession contract requires
Obras Sanitarias Mendoza to expand the water and wastewater connections in the
concession area over the next 10 to 15 years. Through 2015, approximately $180
million is expected to be spent on new connections, new water and wastewater
treatment facilities and system improvements. Obras Sanitarias Mendoza's assets
include raw water transportation pipelines and aqueducts, drinking water
treatment plants and other general assets.
    
 
   
     Water supply comes primarily from the regional river, Rio Mendoza. The
surface water feeds by gravity to treatment plants. The remaining groundwater
comes from approximately 160 wells. Obras Sanitarias Mendoza uses four large
lagoon systems to provide the majority of wastewater treatment within the
concession area. Average billing is approximately $30 bi-monthly for water and
wastewater.
    
 
   
     Obras Sanitarias Mendoza is required to meet standards of service
established by the special purpose regulatory body known as Ente Provincial de
Agua y Saneamiento and to make appropriate arrangements for the improvement and
extension of service. The standards of service include quality and availability
requirements, which are initially set by the concession contract. Each year, the
operator must submit an
    
 
                                       58
<PAGE>   64
 
   
annual report that will specify, among other things, Obras Sanitarias Mendoza's
progress with respect to its plan of operation and expansion.
    
 
   
     Obras Sanitarias Mendoza must pay the Province a yearly royalty based on
net operating revenues collected. This royalty is equal to 3.85% of net
operating revenues collected in the first five years of the concession and 9.98%
thereafter.
    
 
   
     The concession may be terminated for fault of the concession holder under
any of the following circumstances:
    
 
   
     - Repeated failure to provide service as required by the concession
       contract
    
 
   
     - Repeated violation of applicable environmental regulations
    
 
   
     - Unjustified delays in completion of the then-current plan of operation
       and expansion
    
 
   
     - Willful withholding of information from the environmental regulator
    
 
   
     - Failure to maintain adequate performance bonds
    
 
   
     - Any change in the corporate structure of the concession holder or the
       operator without the prior approval of the Province
    
 
   
     The Province can undertake the partial or complete termination of the
concession for noncompliance with the terms of this contract or for public
interest reasons. In the event of a termination for public interest reasons, the
Province must compensate the concession holder for its lost investment. Obras
Sanitarias Mendoza believes it is in compliance with the concession contract in
all material respects. As the concession holder, Obras Sanitarias Mendoza would
be liable for any claims or damages, environmental or otherwise, relating to
this concession. As a shareholder, we believe that our potential liability is
limited to our investment in the concession holder.
    
 
  CANCUN, MEXICO
 
   
     In March 1999, we acquired for $13.5 million a 49.9% economic interest in
and the right to manage and operate the water and wastewater treatment
concession for Cancun and Isla Mujeres, Mexico. Desarrollos Hidraulicos de
Cancun, S.A. de C.V. is the concessionaire that holds the concession. Affiliates
of one of the former shareholders, Grupo Mexicano de Desarrollo, S.A., own an
aggregate 50.1% economic interest in the concessionaire. In February 1999, we
lent the concessionaire $15 million to permit it to retire a portion of its
indebtedness, and we may make additional loans of up to $10 million to initiate
improvements in the wastewater treatment system.
    
 
   
     The concession was initially granted on the condition that the
concessionaire would invest capital in projects to provide services under the
concession. As a result of the devaluation of the Mexican peso in 1994, the
concessionaire was unable to meet some of its investment obligations and the
government of the State of Quintana Roo in August 1996 designated the state
regulatory authority, known as CAPA, to operate the concession. In February
1997, Grupo Mexicano and the concessionaire agreed with the state government
that, as a condition to reassuming operation of and retaining the concession,
the concessionaire would make the necessary investments and form an association
with an experienced operator of water concessions. In general, the parties
involved agreed on the following:
    
 
   
     - The concessionaire would be responsible for adjusting its financial
       statements and making pertinent payments in order to show financial
       stability and sustainability
    
 
   
     - The concessionaire and CAPA would review the capital expenditure program
       for the period 1997-2000 and would implement it immediately after
       approval
    
 
   
     - The parties would reconstruct the concession agreement and develop a new
       one with the National Water Commission (Comision Nacional de Agua) acting
       as a mediator
    
 
                                       59
<PAGE>   65
 
   
     The cost to the concessionaire for these investments is estimated at $44
million over the next five years. The concessionaire is required to pay to the
State of Quintana Roo an annual concession fee of 7.5 million pesos (in 1993
pesos), adjusted annually in accordance with changes in the Mexican consumer
price index. The concession extends to October 2023.
    
 
   
     At the end of the concession term, and any extensions, the concessionaire
will be required to deliver to the government at no cost the facilities and
equipment used to provide services under the concession. The concession may be
revoked by the government in the event of a breach of the concession terms if
the concessionaire does not present a program to cure the breach within 30 days
of notice of default. The concession can be terminated if the concessionaire is
bankrupt, insolvent, liquidated or dissolved. The concession may also be revoked
upon the transfer of part or all of the concessionaire's rights under the
concession without government approval or if the concessionaire does not
maintain a performance bond in an amount equal to 10% of annual operating
revenues for the prior year.
    
 
   
     Based on figures available at the date of acquisition, the concessionaire
serves a population of approximately 390,000 through 73,000 connections. An
estimated 65% of the concession's operating revenues are derived from the supply
of drinking water to tourist hotels, whose operating revenues are primarily U.S.
dollar based.
    
 
   
     The operations and tariffs for water and wastewater systems in the State of
Quintana Roo are regulated by CAPA. The water tariff paid by the hotels,
commercial and industrial customers is adjusted monthly according to the change
in Mexico's consumer price index as published by the Mexican government. In
addition, the concession provides that the rate paid by the hotels will be
increased in the event of a variation of the Mexican peso/U.S. dollar exchange
rate in excess of 15% due to a short-term event. The remainder of operating
revenues come from residential and public services drinking water supply and
from wastewater services. Residential drinking water rates are adjusted annually
with changes in the Mexican minimum wage established by the minimum wage
commission. Currently, less than 40% of the wastewater in the Cancun urban zone
that is collected is being treated.
    
 
   
     The tariff rates, which vary according to the customer class, resulted in
an average billed consumption of 7.95 pesos per cubic meter of water consumed in
1998. Operating revenues and expenses of the concessionaire in 1998 were 205
million pesos ($22.0 million) and 164 million pesos ($17.7 million),
respectively. Operating income in 1998 was 40 million pesos ($4.4 million).
These figures are estimated by management and have not been audited. The U.S.
dollar amounts have been translated based on the April 30, 1999 exchange rate of
9.3 pesos to one U.S. dollar.
    
 
   
     We have three seats on the board of directors of the concessionaire, while
the 50.1% shareholders have two. We have the right to appoint the chief
executive officer, the chief financial officer and the chief operating officer
of the concessionaire. The 50.1% shareholders have the right to appoint the
chairman of the concessionaire's board and the non-voting board secretary.
Resolutions concerning major corporate actions and governance issues require
supermajority approval.
    
 
   
     As the concessionaire, Desarrollos Hidraulicos would be liable for any
claims or damages, environmental or otherwise, relating to this concession. We
believe that our potential liability is limited to our investment in the
concessionaire.
    
 
   
  PHILIP UTILITIES MANAGEMENT CORPORATION
    
 
   
     We entered into an agreement on March 25, 1999 to purchase all of the stock
of Philip Utilities Management Corporation, a water and wastewater services
company headquartered in Hamilton, Ontario, Canada. We will pay a total of $107
million in cash, approximately 68% to Philip Services Corporation and
approximately 32% to Ontario Teachers' Pension Plan Board. The acquisition is
subject to closing conditions, including the receipt of third party and
regulatory consents, the receipt by Philip Services Corporation's secured
lenders of advice regarding the fairness of the purchase price and the release
of all liens, security interests or similar encumbrances on shares of Philip
Utilities. The acquisition is scheduled to close in the second quarter of 1999.

     Philip Utilities operates facilities in three of the ten provinces of
Canada, with a concentration of operations in Ontario, and in the United States
in the states of Arizona, Florida, Georgia, Louisiana, Maine, New Jersey, Texas
and Washington. In calendar year 1998, Philip Utilities had operating revenues
of $100 million. The following is a discussion of Philip Utilities' business
operations.
    
 
   
     OPERATIONS, MANAGEMENT AND ENGINEERING. Philip Utilities' operations,
management and engineering business is divided along two business lines:
contract operations on the one hand and engineering and automation on the other.
    
 
   
     Contract Operations. Philip Utilities' contract operations division
contributes approximately 30% of its operating revenues. Philip Utilities'
largest contract operation projects are in Hamilton-Wentworth, Ontario and
Seattle, Washington. In 1994, Philip Utilities won the contract to operate and
maintain the 192 million-gallon-per-day water treatment facility and the 110
million-gallon-per-day wastewater treatment facility of the regional
municipality of Hamilton-Wentworth. Under the operations agreement, Philip
Utilities receives an adjustable flat fee plus a portion of any cost savings
realized under the contract. Services provided under the operations agreement
include the day-to-day operation, maintenance, repair, and permitting and
compliance of the facility.
    
 
   
     Philip Utilities' second largest contract operation project is the design,
build and operate contract for the 120 million-gallon-per-day Tolt River
Treatment Facility that is currently under construction in Seattle, Washington.
In 1996, Philip Utilities teamed with the engineering firm of Camp Dresser &
McKee, Inc. to win this 15-year contract which is renewable by the City of
Seattle for two additional periods of five years each. CDM Philip, Inc., an
80%-owned subsidiary of Philip Utilities, receives approximately $74.8 million
in design and construction fees. CDM Philip subcontracted the design/build
portion of the contract to Dillingham Construction, N.A., Inc. for approximately
$63 million. Construction of the Tolt River plant is currently on schedule with
the facility scheduled to commence operations in December 2000. Once operations
have commenced, CDM Philip is entitled to an annual service fee of approximately
$1.7 million, subject to modification for incentive bonuses, pass-through costs
and other adjustments.
    
 
   
     Engineering and Automation. Philip Utilities' engineering and automation
activities are based in Ontario and Atlanta, Georgia. Philip Utilities provides
plant design, construction, project management, and process design and
engineering services primarily for municipal customers and other Philip
Utilities operations. Philip Utilities also provides process automation and
instrumentation services including design, assembly, testing and installation of
supervisory control and data acquisition systems and other computer control
technologies primarily for municipal customers. Philip Utilities' engineering
and automation activities contributed approximately 12% of its operating
revenues in 1998.
    
 
   
     RESIDUALS MANAGEMENT. Residuals management accounted for approximately 16%
of Philip Utilities' operating revenues in 1998. Philip Utilities' residuals
management division is comprised of three complementary operations that apply
dewatering and land application methods to residuals management:
    
 
   
     - Trimax Residuals Management, Inc. primarily serves the municipal water
       and wastewater sector, with the majority of its operating revenues
       derived from dredging and removing water from sewage lagoons and tanks.
       Trimax is headquartered in Edmonton, Alberta and conducts operations in
       the United States and Canada. Major contracts are held with the Greater
       Vancouver Regional District, the cities of San Diego and Detroit, as well
       as several pulp and paper companies. Trimax has built its business around
       a mobile water removal technology that provides a great deal of
       flexibility and versatility in the marketplace. The product of this
       process is a manageable biosolid that is typically disposed of through
       land application. Trimax accounted for approximately 63% of Philip
       Utilities' residuals management operating revenues in 1998.
    
 
   
     - Braemar Acres Limited processes industrial wastewater and municipal
       biosolids for disposal through land application. Braemar Acres,
       headquartered in Ontario, has existing operations that are principally
       located within the province of Ontario and include disposal of lime
       sludge for a sugar manufacturer, processing of paper sludge for five of
       the six pulp and paper companies in eastern
    
 
                                       61
<PAGE>   67
 
   
       Ontario, waste food organics recycling, and biosolids for the
       Hamilton-Wentworth facilities and the city of Niagara, Ontario. Braemar
       Acres accounted for approximately 10% of Philip Utilities' residuals
       management operating revenues.
    
 
   
     - Enviroganics of Texas, Inc. is a Houston-based company that provides
       wastewater biosolids management and residuals management services to over
       165 wastewater treatment facilities in Texas. Enviroganics' services
       include removal and processing of biosolids, on-site mobile water
       removal, operation of customer's processing equipment and hauling and
       disposal through land application of biosolids. Services are typically
       rendered under purchase orders instead of long-term contracts.
       Enviroganics accounted for approximately 25% of Philip Utilities'
       residuals management operating revenues in 1998.
    
 
   
     UNDERGROUND INFRASTRUCTURE REMEDIATION AND DEVELOPMENT. Philip Utilities
offers a wide range of underground asset management services to customers in the
United States and Canada. These services include closed circuit television
inspection, location mapping, as well as pipeline repair and rehabilitation.
Since 1996, Philip Utilities has focused on migrating from traditional pipe
rehabilitation to trenchless technologies. Philip Utilities employs a variety of
trenchless technologies for which it holds licenses in various geographic
territories. Among these licensed products are epoxy resins, polyurethane
fold-and-form pipe, a roll-down pipe product, two cured-in-place products and a
spot repair system. The underground infrastructure division contributed
approximately 40% of Philip Utilities' operating revenues in 1998.
    
 
   
     OWNERSHIP OF WATER AND WASTEWATER ASSETS. In addition to its outsourcing
operations, Philip Utilities owns two utilities that serve approximately 3,000
end use customers in suburban areas around Houston, Texas: Southwest Utilities,
Inc. and Walker Water Works, Inc. These two utilities own and operate both water
and wastewater treatment services and are regulated by the Texas Natural
Resource Conservation Commission and the Environmental Protection Agency. This
is Philip Utilities' smallest division and contributed approximately 2% of its
operating revenues in 1998.
    
 
SUPPLIERS
 
   
     We intend to achieve economies of scale in buying goods and services. In
addition, we expect to centralize purchasing arrangements to reduce costs and
improve quality. Wessex's only significant supplier of goods or services is
SEEBOARD plc, a subsidiary of Central and South West Corp., which supplies
electricity to approximately 100 of Wessex's sites. Wessex pays approximately
$6.4 million per year, which represents approximately 5% of Wessex's annual
operating costs. The contract was effective October 1, 1997 and runs for two
years. The price is based upon a negotiated pence amount per kilowatt hour for
each site. Wessex is not dependent on any single supplier, including SEEBOARD,
because its supplies are readily available from alternative sources at market
rates and on similar terms. None of Wessex's suppliers is affiliated with it.
    
 
RESEARCH AND DEVELOPMENT
 
     Since our formation, we have established a link with the Water Research
Centre, which is conducting a U.K. industry-wide research and development
program that currently invests approximately $6.6 million each year in research
programs. The Water Research Centre is internationally renowned as the market
leader in water and wastewater technology. We will have a research department
based within the Water Research Centre at Swindon in the United Kingdom. The
Water Research Centre will also provide us with a service to monitor the
development of water and wastewater technologies across the world and with the
opportunity to access, and, when appropriate, invest in new technologies. Wessex
contributes approximately $160,000 per year to this program.
 
   
     Wessex carries out its own research and development to improve the
reliability and effectiveness of its treatment systems. In-house research and
development projects include development of a mobile filter for wastewater
treatment and disinfection and membrane filtering technology. Wessex has spent
approximately $1.6 million on these two project areas in the last three years. A
third major project area is pasteurization
    
 
                                       62
<PAGE>   68
 
   
of wastewater biosolids using the Swiss Combi heated drying technique. Wessex
has spent approximately $640,000 over the last three years in this area.
    
 
EMPLOYEES
 
   
     As of February 28, 1999, we had approximately 145 employees, excluding
employees of Wessex. As of February 28, 1999, Wessex had approximately 1,440
employees, which includes approximately 50 employees at SC Technology. As part
of its efforts to improve operating efficiencies, Wessex has reduced the number
of its employees by approximately 500 employees since March 31, 1993, primarily
through attrition and voluntary retirement packages.
    
 
INSURANCE
 
   
     We believe that our insurance arrangements, including self-insurance, are
customary for the industry and are adequate. Wessex, Mendoza and Cancun have
separate locally underwritten insurance policies covering employers liability,
public and products liability, excess public and products liability and their
motor fleets. Enron's corporate insurance program covers the direct exposures of
Azurix and the indirect exposures to Azurix from its less than wholly owned
subsidiaries, to the extent not covered by the subsidiaries' policies. Following
the offering, Azurix will continue to participate in Enron's corporate insurance
program. In the future, Azurix may establish a separate program for Azurix and
Azurix's subsidiaries.
    
 
LEGAL PROCEEDINGS
 
     There are no legal or arbitration proceedings, including any that are
pending or threatened, of which we are aware that if adversely determined would
have a material adverse effect on our financial position, liquidity or results
of operations.
 
                                       63

                               REGULATORY MATTERS
 
   
     The following is a summary of regulatory matters relating to water and
wastewater operations in the United Kingdom, Argentina and Mexico. In addition,
the following summarizes regulatory matters in the United States and Canada,
where we intend to operate water and wastewater assets in the future.
    
 
     In general, most countries where we have invested, or intend to consider
investments, have drinking water quality and environmental laws and regulations.
We intend to invest in companies or projects that operate in material compliance
with drinking water quality and environmental laws and regulations. However, we
cannot guarantee that the due diligence we perform in advance of investing in an
entity will identify any or all noncompliance with environmental laws and
regulations by such entities.
 
   
     Because the supply of clean drinking water and the treatment of wastewater
are essential societal needs, we anticipate that these activities will be
subject to at least some form of regulation wherever we do business. The nature
and extent of environmental laws and regulations vary from country to country
and there may be wide disparities in the requirements from one part of the world
where we do business to another. Generally speaking, compliance with these laws
and regulations is mandatory and penalties, as well as injunctive and other
relief, are usually available in the event of noncompliance. Moreover, these
laws and regulations may require improvements to water and wastewater systems
that will require additional capital and operating costs for us to remain in
compliance.
    
 
   
     Changes in the nature of these laws and regulations, or in the level of
their enforcement, also have the potential to impact adversely our financial
results during the relevant period. These adverse impacts could cause our actual
financial results to differ materially from those we project, forecast, estimate
or budget. Moreover, changes in these laws and regulations may require
improvements in order to remain in compliance that can result in additional
capital and operating costs.
    
 
     Where we operate water or wastewater companies serving end-users, we can
expect to be subject to regulation on the rates we may charge. The regulatory
regime will vary from jurisdiction to jurisdiction, but can be expected to
resemble in some respects the regime in place in the United Kingdom, Argentina
or Mexico.
 
     Wessex has established a comprehensive environmental auditing program that
is designed to provide early identification of potential environmental problems
associated with its activities and to provide reasonable assurance that all
identified problems are properly and promptly addressed. We expect to use the
environmental auditing capabilities already established within Wessex to
evaluate potential environmental and other regulatory risks that may be
associated with water and wastewater systems, companies and concessions in which
we may invest. We will also use these capabilities to monitor environmental and
other regulatory compliance in all water and wastewater systems, companies and
concessions in which Azurix or one of its subsidiaries takes an active
management role. Despite the demonstrated effectiveness of this environmental
auditing program with respect to Wessex's operations, however, there can be no
assurance that this approach will be adequate to address and manage all such
risks associated with our business.
 
U.K. REGULATORY MATTERS
 
     The economic aspects of the water industry in England and Wales are
principally regulated under the provisions of the Water Industry Act 1991.
Following privatization of the U.K. water industry, each of the water and
wastewater companies became regulated through a license and the regulatory
provisions of the Water Industry Act 1991 and regulations and orders thereunder.
The license designates the relevant company as a water and/or wastewater
undertaker in its own area and provides for the monitoring of the company's
performance by the Director General for Water Services and the Secretary of
State for the Environment.
 
     In setting prices, the Director is currently required to allow water and
wastewater companies a projected rate of return sufficient to finance their
operations and attract the capital necessary for investments in infrastructures
required to meet environmental and other regulatory standards. The actual
                                       64
<PAGE>   70
 
rates of return achieved by individual companies can vary significantly from the
projected rates of return assumed by the Director in setting prices.
 
   
     Each water company is under a general duty to develop and maintain an
efficient and economical system of water supply within its license area. Each
wastewater company is under a general duty to provide, improve and extend a
system of public sewers and to maintain those sewers to ensure that its sewerage
region is effectively drained. In addition, discharges from wastewater treatment
plants must be licensed by the Environment Agency, and wastewater companies are
responsible for regulating discharges of industrial wastewater into sewers.
Contamination caused by wastewater discharged from a treatment plant may subject
the wastewater company to liability, including clean up costs.
    
 
   
     The Director is responsible for ensuring that water and wastewater
companies comply with their license conditions. Conditions may be modified with
the consent of the licensee after the giving of public notice and consideration
of comments and objections. In the absence of consent, the only means by which
the Director can secure a modification is following a modification reference by
him to the U.K. Competition Commission. The Commission is required to
investigate and report on whether matters specified in the reference may be
expected to operate against the public interest and, if so, whether the adverse
public interest effect of those matters could be remedied by modification of the
conditions of the license. If the Commission makes adverse findings, the
Director must then modify the license accordingly.
    
 
   
     A license may also be revoked or transferred to another company in
circumstances specified under law or in the license. These circumstances include
the failure to comply with an enforcement order made by the Secretary of State
for the Environment or the Director or the inability of the relevant water and
wastewater company to pay its debts.
    
 
  WESSEX WATER SERVICES' LICENSE
 
   
     Wessex's license continues indefinitely, or until such time as the
Secretary of State serves notice of revocation of the Wessex license. The
effective date of revocation, under the terms of Wessex's license, cannot occur
prior to 2014. In the event that Wessex becomes insolvent or it is determined
that Wessex has committed a material breach of its duties, the Secretary of
State, or, with his consent, the Director, may seek a special administration
order, under the terms of which Wessex's affairs, business and property may be
transferred to another company in order to ensure that Wessex's appointed
functions can be carried out. In either event, the legislation provides for
Wessex's assets to be transferred to the new replacement appointee on terms
approved by the Director or the Secretary of State, including as to
consideration to be paid by the new appointee. The license sets out the charging
formula imposed on Wessex, which is subject to review every five years. The
formula is tied to the retail price index plus an adjustment factor which can be
positive, zero or negative. The adjustment factor is set by the Director on a
case by case basis for each company at the review to bring the companies in line
with the target rate of return set by the Director. The license regulates the
fees that Wessex can charge new customers upon connecting them to the water or
wastewater network. It requires Wessex to fix its rates and prohibits Wessex
from unduly discriminating against any individual or class of customer with
respect to charges.
    
 
   
     Wessex is required to maintain sufficient financial and managerial
resources to carry out the appointed business and necessary investment. The
license requires it to publish separate accounts, including on a current cost
accounting basis showing its regulated business separately from all other
businesses and activities. Regulated businesses, such as Wessex, are subject to
business practices limitations, such as restrictions on cross-subsidies, that
restrict affiliate dealings and promote competitive contracting. The license
also requires Wessex to put in place financial structures protecting a
sufficient amount of its assets so that its water and wastewater services could
still be provided in the event of Wessex's insolvency.
    
 
   
     The license includes service targets which apply to Wessex and are
monitored by the industry regulator. The license also requires Wessex to pay
annual fees, based on Wessex's revenues, which are intended to cover the costs
of the regulation of the water industry. In 1998, Wessex paid approximately
$665,000 in such fees.
    
 
                                       65
<PAGE>   71
 
   
     The license has been modified as a condition of regulatory clearance of
Azurix's acquisition of Wessex to address regulatory concerns arising out of the
acquisition. In particular, the modification strengthens the financial
independence of Wessex Water Services' regulated business, providing of water
supply and wastewater services, by imposing the following:
    
 
   
     - Restrictions on transfers of assets, guarantees, intercompany loans and
       loans containing cross-default provisions
    
 
   
     - A requirement that transactions with associated companies must be entered
       into on an arm's length basis at market rates
    
 
   
     - A requirement to maintain an investment grade rating for corporate debt
       of Wessex Water Services
    
 
   
     The license as modified also requires a dividend policy to be agreed with
the Director that ensures that Wessex Water Services retains sufficient funds to
finance its core activities and requires Wessex Water Services to conduct its
regulated business as if a separate public limited company. Enron gave a holding
company undertaking that requires, among other things, that Enron and its
affiliates give Wessex Water Services all information necessary for it to carry
out its obligations and to refrain from action that would cause Wessex Water
Services to breach its obligations. This undertaking also provides that the
board of Wessex Water Services must include at least three independent
non-executive directors of standing and relevant experience.
    
 
  TARIFF RATES
 
   
     The Director regulates prices and service levels. Price controls applicable
to each water and wastewater company are subject to review by the Director every
five years, but both the Director and the individual company may seek an interim
determination to adjust price limits between the periodic reviews in limited
circumstances.
    
 
     Unlike "rate of return" economic regulation, such as exists for many U.S.
industries, regulation in the United Kingdom generally uses forms of "price
limitation." This is intended to reward companies for efficiency and quality of
service to customers. The U.K. regulatory system allows companies to retain for
a period of five years any savings attributable to efficiencies that they are
able to achieve. In the case of water, the main instrument of economic
regulation is a price limitation formula set out in each company's license. This
formula limits charges made by water and wastewater companies for a basket of
principal regulated services. The limit is expressed as a percentage change by
reference to the retail price index. This adjustment can be positive, zero or
negative and is determined in light of past operational efficiencies, assumed
future operational efficiencies, investments to meet water quality standards,
expenditures to enhance security of supply and service levels and an appropriate
return on capital.
 
     During the prior periodic review, completed in July 1994, the Director
developed a structure for determining adjustment factors based on a matrix of
purpose and cost categories. The purpose categories comprised of base service
provisions, the maintenance of existing levels of service, as well as enhanced
service levels, the water supply/demand balance and obligatory quality
enhancements. The limits on Wessex's real price changes, i.e., in addition to
the retail price index, resulting from the 1994 periodic review were +1.5% for
each year until March 31, 2000.
 
     The Director is currently conducting a periodic review, to conclude in
November 1999 when he will set new price limits for the period from April 1,
2000 to March 31, 2005. As part of the current review process, on October 29,
1998, the Director published a consultation paper setting out proposed ranges
for bills for the period from 2000 to 2005. The Director has confirmed that, on
the basis of past efficiencies achieved by water companies and evolving views
about the cost of capital, he expects substantial price reductions in April
2000. However, the U.K. Government has recently proposed a five-year program of
mandatory capital expenditures by the water companies aimed at quality and
environmental improvements. This program is estimated to cost the industry $13.3
billion in the aggregate over the five years. In setting
 
                                       66
<PAGE>   72
 
the new price adjustment factor, the Director will make an allowance for the
investment needed to meet new quality and environmental obligations.
 
   
     The Director proposed, in the case of Wessex, that expected average
household bills, in real terms, could be over 17.5% lower in 2000-2001 than in
the previous year, but that bills overall would rise, by 2004-2005, to a level
exhibiting only a small reduction compared with the expected 1999-2000 bill.
This would constitute a material increase in prices following the one-time
reduction in 2000-2001. The Director's proposal did not take into account the
recent capital expenditure proposals of the U.K. Government. The Director has
invited views on whether the one-time reduction is appropriate or whether the
initial reduction could be modified so that bills could be broadly stable over
the five year period. The Director's estimates for future bills assume that the
scope for efficiency savings across the industry in operating costs could vary
between 2% and 4% a year, and that for capital expenditure the average overall
scope for efficiency is between 10% and 15% over the five year period. They also
assume a post-tax cost of capital of 5.25% for all but the smaller companies.
    
 
   
     The Director held formal meetings with each of the water and wastewater
companies during January and February 1999 to discuss the issues raised by a
proposed price reduction including the responses of the public. In its April
1999 business plan filed with the Director, Wessex proposed stable prices from
1999-2000 to 2000-2001, with prices gradually increasing to 18% higher than
current levels in 2005, primarily to fund capital expenditures mandated by the
new environmental standards. The business plan will be considered by the
Director as part of the periodic review. The Director has stated that he will
publish his draft determination of new price limits to run from 2000 to 2005 in
July 1999, with his final decisions made in November 1999. If a company
disagrees with the Director's price determination, it may challenge his proposal
by requesting a reference to the Competition Commission. Although we are unable
to predict the precise outcome of the current U.K. rate review, if Wessex were
required to cut its prices as originally proposed by the Director, Wessex's
revenues would be reduced by approximately 17.5% and its earnings would be
reduced materially. However, we would not expect that this would have a material
adverse effect on Azurix's financial position. At the time of the acquisition of
Wessex, we took into consideration the pending rate review in our valuation of
Wessex.
    
 
  CHANGE TO REGULATORY REGIME
 
     On June 30, 1997, the U.K. Government launched a review of the framework
for the regulation of all utilities, and in March 1998 set out its proposals in
a consultation paper.
 
   
     In July 1998, following the consultation, the U.K. Government published its
response. Among other things, it suggested that:
    
 
   
     - Consumer protection should be the Director's primary duty achieved
       wherever possible and appropriate through promoting effective
       competition, but also taking into account the need to ensure that
       regulated companies are able to finance the carrying out of their
       functions
    
 
   
     - There should be consumer representative bodies to promote consumer
       interests
    
 
   
     - A clearer link should be made between the prices utilities can charge and
       the customer service standards they achieve
    
 
   
     - Full information should be available on companies' performance on
       customer service standards and on the links between this performance and
       the remuneration of directors
    
 
   
     - Ministers should issue statutory guidance on social and environmental
       objectives
    
 
   
     On publishing the response, the Secretary of State for Trade and Industry
stated an intention to introduce legislation to implement the proposals as soon
as parliamentary time permits. In his March 1999 Budget Speech, the Chancellor
of the Exchequer announced that the Deputy Prime Minister will review
competition in the water industry.

  DRINKING WATER QUALITY AND ENVIRONMENTAL REGULATION
 
     The water and wastewater industries in England and Wales are subject to
numerous environmental regulatory requirements under the Water Industry Act
1991, the Water Resources Act 1991 and the Environment Act 1995. The Water
Industry Act 1991 established a new, more extensive and more stringent quality
regime for the water and wastewater industry through the creation of the
National Rivers Authority, since replaced by the Environment Agency, and the
Drinking Water Inspectorate.
 
     The Drinking Water Inspectorate is responsible for ensuring that water
supplies meet the standards set out in the U.K. Water Quality Regulations. The
licensed Inspectorate conducts technical audits to assess annually the quality
of the drinking water supplied by the licensed companies. If any company fails
to meet the relevant water quality standards, the Inspectorate may require it to
take any necessary remedial action.
 
   
     Under the Water Resources Act, the Environment Agency may require persons
to take precautions against pollution, may prohibit or restrict activities
likely to cause pollution in areas designated by the Secretary of State for the
Environment, and may issue consents to discharge matter from a drain or sewer.
When reviewing existing consents and issuing new ones, the stated practice of
the Environment Agency is to seek to set conditions at the level required to at
least maintain and, where appropriate, improve the quality of the receiving
waters.
    
 
   
     The activities of the U.K. water and wastewater companies are also affected
by the requirements of European Union directives, including the Drinking Water
Directive, the Bathing Waters Directive and the Urban Wastewater Treatment
Directive, each of which has been brought into force in the United Kingdom. The
environmental systems which Wessex has in place are designed to comply with
European Union and U.K. requirements.
    
 
     In May 1997, the Secretary of State for the Environment announced a review
to examine ways in which environmentally damaging abstractions can be equitably
curtailed. The review will consider arrangements to reduce abstractions under
existing licenses and for revoking licenses in areas where pumping causes
significant environmental damage. He has also announced that the Director will
be setting mandatory targets to reduce leaks from water supplies, which will be
reviewed annually. Failure to meet the targets would carry penalties and could
ultimately lead to a water and wastewater company being put into the hands of an
administrator appointed by the Director.
 
   
     In view of the age and history of many sites owned by Wessex, Wessex may
incur liability for sites that are found to be contaminated, resulting in
increased costs of managing or cleaning up such sites. Environmental legislation
requires the polluter (or if the polluter cannot be found, the owner or
occupant) of contaminated land to clean up any contamination which causes, or is
likely to cause, significant harm to the environment. Polluters are also
required to clean up any pollution of water sources. Other proposals which may
impose strict liability for environmental damage are also under consideration by
the European Union. Wessex expects that the direction of future changes will be
towards further tightening of controls. However, Wessex does not believe that
any liability which it may incur under environmental legislation or published
European Union directives will have a materially adverse effect on its results
of operations, financial position or liquidity.
    
 
ARGENTINE REGULATORY MATTERS
 
  GENERAL REGULATION OF WATER
 
     Argentina has a federal system of government that grants significant
regulatory powers to the provinces. Under the Argentine Constitution, each
province has jurisdiction over its own natural resources, including water, and
the legal power to create standards to protect such resources.
 
     Federal laws apply to areas within national jurisdiction, such as the
federal capital, and to matters which affect the nation as a whole and not
merely one province. At the national level, the Secretariat of Natural Resources
and Sustainable Development is principally responsible for the protection of the
 
                                       68
<PAGE>   74
 
environment, and the Ministry of Health and Social Action is principally
responsible for the protection of public health. The Secretariat of Natural
Resources and Sustainable Development also is responsible for the development
and implementation of national water policy and for establishing priorities of
uses for multiple-use water resources.
 
   
     Under the Argentine Constitution, the provision of water services at the
local level generally is within the authority of the provinces and
municipalities. In the Province of Mendoza, for example, the Ministry of Public
Works and the Environment is granted general authority over all non-agricultural
water services, and environmental regulation. Concessions for the provision of
water services are granted by the provincial government by statute and decree,
with oversight vested in the Ministry of Public Works and in a special purpose
regulatory body known as EPAS. Decisions of EPAS may be reviewed by the Minister
of the Ministry of Public Works and the Governor of the Province of Mendoza.
    
 
  REGULATION OF WATER SERVICE AND TARIFF RATES
 
     In Argentina, provision of local water service and tariff rates are
generally controlled by provincial regulatory authorities, through a framework
established by statute and concession contracts. Governmental acts are subject
to judicial review in Argentine courts, but there is no right to appeal
provincial decisions setting tariffs to the Argentine federal government. Where
a water service concession is held by a company substantially owned by a U.S.
company, however, recourse may be available through international arbitration
under the Bilateral Investment Treaty between the United States and Argentina,
which provides for fair and nondiscriminatory treatment of investments.
 
   
     The Province of Mendoza provides an example of the process of granting
concessions and setting tariffs on a provincial level in Argentina. In Mendoza,
the basic regulatory framework is established by provincial statutes and
decrees. Within that framework, EPAS and the Ministry of Public Works regulate
the provision of service and the setting of tariffs.
    
 
   
     TARIFFS. In Mendoza, tariffs are proposed by the local regulatory agency,
EPAS, and then submitted to the Minister of the Ministry of Public Works, the
provincial legislature and Governor for approval. EPAS must recommend rate
regimes with an aim to reflect efficient costs of operation, maintenance and
expansion and renewal of the water system, including debt service. EPAS also
strives to promote rational and efficient use of services and resources leading
to a balance of supply and demand, and to address sanitation and social
objectives. EPAS is authorized to establish tariff rates that require some users
to pay rates that subsidize the cost of providing service to other users.
Argentine law provides that in setting tariffs, EPAS must take into account
costs of operations, maintenance, amortization of services and a "reasonable"
rate of return for the concessionaire in the context of an efficient level of
operation. The basic tariff regime is to be reviewed every five years.
    
 
     The current tariff schedule imposes a fixed monthly charge per customer,
based on a formula which takes into account the customer's land area, types and
size of structures and uses of the land, that normally will remain unchanged
until the new tariff regime is implemented. Changes in current tariffs are
allowed for several enumerated reasons, including if operating costs increase or
decrease by 4% as reflected in official national indices, if there is a change
in the national "convertibility law" which establishes a 1:1 exchange rate of
the peso with the dollar, if there are changes in the capital program due to
government or regulatory reasons, or if there are changes in taxes, other than
income taxes.
 
   
     A new tariff regime is to be implemented in Mendoza within the next several
years based on a metered charge per liter of water used. The concession contract
contains assurances that the concessionaire will receive the same level of
revenue as under the prior regime, thus allowing the concessionaire to retain
efficiency gains and pass through changes in costs. The contract contains no
provision for direct pass through for inflation or revisions in tariffs for
capital expenditures. The concessionaire may request adjustments to the new
tariff if any of the following occurs:
    
 
   
     - The new tariff lowers consumption significantly
    
 
                                       69
<PAGE>   75
 
   
     - The concessionaire shows that the new tariff does not promote rational
       use of the assets and capital employed for the operations of the company
       or does not allow it to carry out the obligations of the company
    
 
   
     - The concessionaire shows that most of the benefits of cost reductions are
       inuring to consumers
    
 
  ENVIRONMENTAL MATTERS
 
     Beginning in the early 1990s, Argentina began addressing environmental
matters systematically at the federal level. For instance, in 1991, the
Argentine government enacted a law establishing the Secretariat of the
Environment and calling for a balancing of economic development with the
conservation of natural resources, the improvement of the environment and the
prevention and amelioration of the effects of pollution. In August 1994, the
Argentine Constitution was amended to assure the right of all residents of
Argentina to a healthy environment and granted the Argentine government
authority to establish minimum standards of environmental protection which are
to be implemented by the provinces. The 1994 amendments to the Constitution also
provide that damage to the environment must be repaired immediately in
accordance with applicable law, and prohibit the importation of actually or
potentially toxic or radioactive waste. In 1995, the Argentine government
initiated a program to protect the environment by promulgating rules regarding
water, land, air and noise pollution and hazardous substances.
 
   
     Throughout Argentina, the provinces take the lead in regulating discharges
of pollutants into waterways. These provinces typically set permissible
standards for pollutant levels in the discharges, issue permits and enforce
them. In Mendoza, wastewater discharges are regulated at the provincial level by
the Ministry of Public Works, which has adopted laws respecting water quality.
As in most provinces in Argentina, the Ministry of Public Works issues permits
and regulates discharges of pollutants into water bodies. In addition, the
concessionaire is required to comply with the drinking water quality standards
set by the concession contract and enforced by EPAS. The Argentine government
can enforce the provisions of the Argentine Civil and Criminal Codes against the
concessionaire.
    
 
     Most provinces in Argentina have also adopted their own regulations for air
and waste as well. The various provincial laws establish different compliance
and enforcement requirements.
 
MEXICAN REGULATORY MATTERS
 
  WATER PROVISION ISSUES
 
   
     Article 27 of the Mexican Constitution reserves water resources to the
nation. Article 115 of the Mexican Constitution places responsibility for
providing public services, including water and wastewater treatment, on the
municipalities with the participation of the State when required by law. The
Ministry of Environment, Natural Resources and Fisheries, through the National
Water Commission, is responsible for:
    
 
     - Assigning water rights and discharge rights to users and assessing the
       relevant fees
 
     - Enforcing water-related environmental regulations
 
     - Planning the efficient development of water resources
 
     - Developing regulatory, legal and financial structures for water
       concessions at the municipal level with an emphasis on private
       participation
 
     - Providing technical assistance to local water authorities and advising on
       project feasibility
 
     - Providing financial support for priority water projects, particularly in
       low-income areas
 
   
     The states and municipalities are responsible for setting conditions for
concessions and for establishing a tariff structure for all customer groups,
collecting payments from customers and paying the National Water Commission for
use of water rights. The Cancun concession is regulated by Concession Integral
de los Servicos de Agua Potable, Alcantarillado Sanitario y Saneamiento,
referred to as CAPA, an agency of
    
 
                                       70
<PAGE>   76
 
the State of Quintana Roo. One of the requirements of the concession is that the
concessionaire achieve and maintain a 95% connection rate for water and
wastewater for the population. Changes to the connection rate requirement will
be subject to the mutual consent of both CAPA and the concessionaire.
 
   
     The Governor of the State of Quintana Roo appoints the members of CAPA. If
the Governor is not supportive of the concessionaire, CAPA may be less inclined
to approve concessionaire initiatives and less understanding of problems it
encounters. Azurix believes Desarollos Hidraulicos, the concessionaire, has good
relations with the state's governor elect.
    
 
  TARIFF RATES
 
   
     The tariff rates are set by CAPA and are based on the principle of full
recovery of operations and maintenance costs and can be revised to maintain the
economic equilibrium of the concession. There is no provision that tariffs
should provide a return on equity or permit the concessionaire to earn a profit.
    
 
   
     Initial tariffs were set when the concessionaire was first awarded the
concession in October 1993. At current levels, the tariffs are sufficient to
cover cost of operations, capital expenditures required under the concession and
return on investment. These expenditures should not necessitate a real tariff
increase over the term of the concession. However, should significant,
unexpected capital expenditures be required, the concessionaire can propose to
CAPA a tariff increase.
    
 
   
     CAPA has indicated that it intends to change the tariff rate in the near
term to eliminate the cross-subsidy between water and wastewater. Currently,
wastewater service is charged a flat rate of 20% of the water bill, regardless
of actual usage. This would have the effect of increasing wastewater rates and
reducing water rates. If the concessionaire wants to increase rates in real
terms, it will be required to submit a rate case to CAPA, with supporting
economic and financial documents explaining the reason for the increase. In all
cases, the real rate for the residential and communal customer classes shall not
exceed the combined operation and maintenance cost of supplying those customers.
The concession will be evaluated every five years to determine whether real
tariff increases are justified. However, the concessionaire may propose real
increases at any time, though CAPA's consent must still be obtained.
    
 
     Under the terms of the concession amendments, the concessionaire is
permitted to disconnect a customer for non-payment.
 
  ENVIRONMENTAL MATTERS
 
   
     The concessionaire has represented to Azurix that it is and has been in
compliance with all state and federal environmental standards associated with
the operation of the concession and that there are no outstanding non-compliant
environmental issues with the state and federal agencies associated with the
concession's operation. If the representation made by the concessionaire is
incorrect, then any environmental liability will be a liability of the
concessionaire. In any event, the concessionaire and an affiliate of the former
shareholders must indemnify Azurix up to $300,000.
    
 
   
     The wastewater plants operated by the concessionaire are designed to
discharge an effluent containing no more than 30 mg/l of total suspended solids
and biochemical oxygen demand. The Mexican federal quality criterion for the
saltwater injection discharge that is operated by the concessionaire is 70 mg/l
of total suspended solids and biochemical oxygen demand. With the completion of
the plant under construction, the existing biosolid management system will need
to be modified or expanded to manage the disposal of the additional volume of
biosolids that will be produced, and other environmental systems will need to be
reevaluated for ongoing operations. The majority of the planned capital
expenditures is dedicated to the improvement of the wastewater collection and
treatment system, and we believe that the amounts planned are sufficient to meet
treatment goals and environmental regulations.
    
 
U.S. REGULATORY MATTERS
 
   
     The business sectors in which we intend to operate in the United States are
generally highly regulated by national, state and local laws and regulations.
Although we do not currently have operational assets in
    
                                       71
<PAGE>   77
 
   
the United States, compliance with these regulations will likely be an important
aspect of our operations in the future.
    
 
  TARIFF RATES
 
     In the United States, the rates for water and wastewater services are
generally subject to state and local laws and regulation. Although the system is
highly fragmented among jurisdictions, most jurisdictions in the United States
utilize "rate of return" economic regulation in setting water and wastewater
rates. Under rate of return economic regulation, the service provider is allowed
to recover its reasonable and necessary operations and maintenance expenses, and
a recovery of and a reasonable return on its invested capital. In most
jurisdictions, a water or wastewater service provider is required to keep a
current set of tariffs on file with the governing regulatory authority. A
service provider generally can charge less than the approved tariffs. Typically,
a service provider cannot change its rates without the approval of the governing
regulatory authority. We can give no assurance regarding our ability to obtain
approvals for rate changes, given the vast number of regulatory authorities with
jurisdiction over water and wastewater service in the United States, and the
fact that decisions regarding rate changes are often subject to political, as
well as economic, factors.
 
  DRINKING WATER QUALITY
 
   
     The Safe Drinking Water Act directs the EPA to set drinking water standards
for the approximately 55,000 community water supply systems in the United
States. The Safe Drinking Water Act Amendments of 1996 bring important changes
to the regulation and financing of water systems. The amendments have several
potentially significant regulatory initiatives, which include the following:
    
 
     - Recent adoption of two rules that may require more sophisticated
       treatment. First, the disinfectants and disinfection by-products rule,
       establishes maximum residual disinfectant levels for chlorination and
       maximum contaminant level goals for potentially harmful disinfection
       by-products. Second, the enhanced surface water treatment rule focuses on
       treatment requirements for waterborne pathogens, particularly
       cryptosporidium.
 
     - A requirement that the EPA list 30 previously unregulated contaminants
       for monitoring, risk assessment, and potential regulation at least once
       every five years. The new Act also specifies that the EPA shall study
       radon, arsenic and sulfates and propose rulemakings in 1999, 2000 and
       2001, respectively, if the EPA determines that these chemicals threaten
       the public health. Such a program poses the risk of additional
       contaminants being regulated as the EPA implements this research, with
       the attendant risks of potentially increased capital and operational
       costs.
 
   
     - Adoption of regulations to reduce lead and copper in drinking water.
       Water providers that exceed specified levels of lead and copper in
       drinking water may be required to perform additional monitoring and
       develop measures to reduce the lead and copper content.
    
 
     The EPA has other long-term plans to develop regulations governing the
treatment of drinking water, such as the recycling of filter backwash into
influent streams at public utilities and additional groundwater disinfection. It
is unclear what precise form these and other regulations will take, so potential
regulatory risks and costs of compliance cannot be evaluated at this time. As is
true for any drinking water provider, if we operate water assets in the United
States, we will face the risk that water we will provide could be contaminated,
including for reasons outside our control and such contamination could expose us
to regulatory sanctions and potential liability for injury to persons and
property.
 
                                       72
<PAGE>   78
 
  ENVIRONMENTAL MATTERS
 
     Among other things, environmental laws and regulations in the United States
generally set requirements for:
 
     - The quality of the discharges from treatment facilities
 
     - The handling and disposal of biosolids from treatment facilities
 
     - The management of associated materials and wastes
 
     - Good housekeeping practices for the management and monitoring of the
       operations
 
     We intend to invest in companies or projects that operate in material
compliance with environmental laws and regulations. It is impossible, however,
to predict how the precise regulatory framework governing companies in which we
will invest will operate.
 
   
     Changes in environmental laws and regulations, or in the level of their
enforcement, may adversely impact our financial results. These adverse impacts
could cause our actual financial results to differ materially from those we
project, forecast, estimate or budget. Moreover, changes in these laws and
regulations may require improvements in order to remain in compliance that can
result in additional capital and operating costs. Environmental protection
statutes in the United States typically provide for the imposition of
substantial civil and criminal penalties, as well as the possibility of permit
revocation and corrective action orders, for violations of their requirements.
These laws may also provide for retroactive, strict liability without regard to
a party's negligence or fault.
    
 
     The Federal Water Pollution Control Act, known as the "Clean Water Act,"
establishes a system of standards, permits and enforcement procedures for the
discharge of pollutants from industrial and municipal wastewater sources. The
law requires permits for discharges from water treatment facilities and sets
treatment standards for industries and wastewater treatment plants. Discharge
permits issued under the Clean Water Act are subject to renewal once every five
years. When discharge permits are renewed and reissued, it is customary for the
EPA or the state agency issuing the permit to impose more stringent discharge
limitations in the new permit. In addition, the EPA and the states have been
establishing new standards for bodies of water that receive wastewater treatment
plant discharges and these new standards may result in the imposition of more
stringent effluent limitations as discharge permits are renewed. Compliance with
these requirements is monitored closely and the Clean Water Act provides the EPA
with an array of enforcement mechanisms for companies that fail to comply,
including penalties and injunctive relief. Additionally, the EPA has recently
published regulations of the use and disposal of biosolids when they are applied
to land or incinerated. Although controls on biosolid disposal may be tightened,
we believe it unlikely that the EPA would take drastic measures such as banning
the land application of biosolids. Although we cannot predict the nature of
these and other regulations under the Clean Water Act, we do not believe that
such regulations will materially harm our business.
 
     Other U.S. environmental laws and regulations may also impact Azurix. These
include the Clean Air Act, the Resource Conservation and Recovery Act, and the
Comprehensive Environmental Response, Compensation and Liability Act. Generally
speaking, responsibility for implementing and enforcing the regulations
promulgated by the EPA under the Clean Air Act and RCRA rests with individual
states, whereas CERCLA is administered by the EPA itself. In some instances,
state regulations have established standards that are more demanding than the
federal standards. Although we anticipate that Azurix's industrial wastewater
treatment services business will focus primarily on the operation and management
of on-site wastewater treatment facilities, Azurix may also operate and manage
facilities that receive and treat third party industrial wastewater that is
generated at an off-site location. Biosolids and other residues resulting from
the treatment of industrial wastewater, particularly wastewater from third party
off-site generators, may be subject to classification as "hazardous waste" under
RCRA and consequently become subject to more stringent handling and disposal
requirements imposed under RCRA.
 
                                       73
<PAGE>   79
 
     We believe that Azurix possesses the expertise necessary to comply with all
U.S. environmental laws applicable to Azurix's operations. We also expect that
our U.S. operations will be subject to a comprehensive environmental auditing
program similar to the program that Wessex has implemented for operations in the
United Kingdom that is designed to provide early identification of potential
environmental problems and to provide reasonable assurance that identified
problems are properly and promptly addressed. Nevertheless, there can be no
assurance that our operations will comply with all environmental laws at all
times.
 
   
CANADIAN REGULATORY MATTERS
    
 
   
     Although we do not currently operate in Canada, Philip Utilities, which we
have agreed to acquire, has operations in Canada. Water and wastewater treatment
operations in Canada are subject to comprehensive federal, provincial and local
laws, regulations and guidelines pertaining to the provision of drinking water
and wastewater treatment services, as well as protection of the environment.
These laws and implementing regulations and guidelines establish standards for
the quality and quantity of effluent discharged from wastewater treatment
facilities, the handling and disposal of biosolids and other generated wastes
and materials, and the treatment and distribution of drinking water to
customers. Water and wastewater treatment facilities may only be constructed
after required environmental permits, certificates and approvals have been
obtained from appropriate governmental agencies. These facilities must then be
operated in compliance with the terms and conditions found in those permits,
certificates and approvals. Some Canadian provinces also regulate and control
the quality of drinking water, using standards relating to the design,
construction and operation of water facilities that may be more burdensome than
federal requirements. Moreover, there are extensive federal and provincial laws,
regulations and guidelines relating to the proper management and safe control of
biosolids and other wastes and materials that are accumulated at water or
wastewater treatment facilities and require proper disposal. The failure to
comply with these laws, regulations and guidelines or any applicable permits,
certificates and approvals may result in the assessment of fines, penalties or
administrative orders.
    
 
   
     We are currently evaluating the regulatory compliance status of a number of
water and wastewater treatment operations in Canada that Azurix hopes to acquire
within the next year. We believe that technical and operating personnel at
Azurix possess the expertise necessary to ensure that any water or wastewater
treatment concessions acquired in Canada will be operated in compliance with
applicable Canadian laws, regulations and guidelines, but there can be no
guarantee that these operations will comply with all environmental laws,
regulations and guidelines at all times. Any new environmental laws, regulations
and guidelines, changes to existing laws, regulations and guidelines, or more
stringent terms and conditions in permits, certificates or approvals relating to
facilities we operate may result in additional regulatory compliance costs that
may or may not be recoverable through rate increases. Nevertheless, we do not
expect any new or changed laws, regulations and guidelines or the modification
of any permits, certificates or approvals to be any more burdensome to the
operations of Azurix than any other water and wastewater treatment services
company performing similar operations in Canada.

BOARD OF DIRECTORS
 
   
     Our Board of Directors will be divided into three classes serving staggered
terms. Directors in each class will be elected to serve for three-year terms and
until their successors are elected and qualified. Each year, the directors of
one class will stand for election as their terms of office expire. We expect
that, after the offering,           ,           and           will be designated
as Class I directors, with their terms of office expiring in 2000;           ,
          and           will be designated as Class II directors, with their
terms of office expiring in 2001; and           ,           and           will
be designated as Class III directors, with their terms of office expiring in
2002.
    
 
     Following the offering, we will appoint two individuals independent of
Azurix, Enron, Marlin Water Trust and Atlantic Water Trust to serve on our Board
of Directors.
 
     The Board of Directors expects to establish an Audit Committee and a
Compensation Committee. The Audit Committee of the Board of Directors will
include at least two independent directors. The Audit Committee will review and
report to the Board of Directors with respect to the selection, retention,
termination and terms of engagement of our independent public accountants, and
maintain communications among the Board of Directors, the independent public

Compensation Committee will consist of at least two persons who are outside
directors within the meaning of Section 162(m) of the Internal Revenue Code of

     Effective May, 1998, Rebecca P. Mark entered into an employment agreement
with Enron through December 31, 2001 as Chairman of Enron International and Vice

                                       78
<PAGE>   84
 
   
February 1, 1999, in connection with Ms. Mark's assumption of the role as
Chairman and CEO, Azurix, in addition to her role as Vice Chairman, Enron. The
agreement with Enron and Azurix provides for an annual salary of not less than
$710,000. Under the terms of the agreement, in May, 1998, Ms. Mark was granted
100,000 Enron stock options that have a ten-year term and vest 33 1/3% on each
of January 1, 1999, January 1, 2000 and January 1, 2001, and 350,000 Enron stock
options which have a ten-year term that vest 33 1/3% on each of May 4, 1999, May
4, 2000 and May 4, 2001. The agreement also stipulated Ms. Mark's 1998 bonus
target to be one percent of Enron International's after-tax net income subject
to adjustment in the sole discretion of Enron's Chairman and CEO taking into
consideration after-tax net income and funds flow targets set each year by the
Board of Directors, as well as other performance criteria. The agreement further
stipulates that bonus calculations for 1999 through 2001 will be determined
prospectively. Further, the agreement provides that Ms. Mark is eligible to

program or the Azurix stock incentive plan. During the term of this agreement,
Ms. Mark was granted 2,000,000 Azurix stock options from the Azurix stock
incentive plan, effective February 2, 1999, which will vest 25% per year over
the next four-year period. The agreement also provides for full vesting of
specific grants and awards made to Ms. Mark under long term incentive plans
maintained by Enron in the event of involuntary termination, death or disability
and, as amended in February, 1999, precludes full vesting of long term grants
made under the Azurix stock incentive plan in the event of termination. The
agreement as amended provides 100% of base pay and unpaid bonuses through the
contract term in the event of involuntary termination. The employment agreement
contains noncompete provisions in the event of Ms. Mark's termination of
employment.
    
 
   
     Effective February 16, 1999, Rodney L. Gray entered into an employment
agreement with Azurix. The agreement, which runs through February 15, 2004 and
entitles Mr. Gray to an annual salary of $430,000, provides that Mr. Gray will
participate in an annual incentive plan with a bonus target of 100% of his
annual base salary. The agreement provides that Mr. Gray is eligible to
participate in the Azurix stock incentive plan. Under his agreement, Mr. Gray
was granted 1,000,000 Azurix stock options, effective February 2, 1999, which
will vest 20% per year over the next five-year period. If Mr. Gray is

then he will receive a monthly severance payment equal to 100% of his monthly
salary and annual bonus payments until the end of the term of the agreement as
if he had not been terminated. The agreement prohibits Mr. Gray from competing
with Azurix until February 15, 2004.

was granted 1,000,000 Azurix stock options, effective February 2, 1999, which
will vest 25% per year over the next four-year period. If Ms. Martin is
involuntarily terminated, which includes a termination by Azurix without cause,

of $250,000. The agreement provides that Mr. Kulpecz will participate in an

on each anniversary of the date of grant and 30,000 Enron stock options which

involuntarily terminated, which includes a termination by Azurix without cause,
then he will receive a monthly severance payment equal to 100% of his monthly
salary until the end of the term of the agreement as if he had not been
terminated plus a pro rata portion of his bonus earned for the year of
termination. In addition, in the case of involuntary termination except if he
has failed to meet performance objectives, Mr. Kulpecz will be entitled to a
payment so that the value of the equity in Enron and Azurix which he has

Mr. Skellett's 60th birthday. The agreement provides that Mr. Skellett will
participate in an annual bonus plan. The agreement prohibits Mr. Skellett from
competing with Wessex for one year following termination of employment.
    
 
STOCK PLAN
 
     We have adopted a stock incentive plan. Grants of incentive stock options
and nonqualified stock options and awards of restricted stock may be made
pursuant to the stock plan. At any particular time, the number of shares of
common stock issued under the plan plus the number of shares of common stock
issuable upon the exercise of all outstanding stock options under the plan may
not exceed 15% of the total number of shares of common stock then outstanding,
assuming the exercise of all outstanding options. The stock plan will be
administered by the Stock Plan Committee, which consists of Rebecca P. Mark,
Kenneth L. Lay and Jeffrey K. Skilling. The exercise price for an option granted
under the stock plan will be determined by the Stock Plan Committee and will be
no less than the fair market value of the common stock on the date that the
option is granted. If our outstanding common stock is adjusted because of a
recapitalization, stock split, combination of shares, reclassification, stock
dividend or other similar change, the Stock Plan Committee will make appropriate
adjustments to the total number of shares covered by the plan and the exercise
price and number of shares covered by each outstanding option or restricted
stock award.
 
     As long as Enron owns 30% or more of our common stock, if there is a change
in control of Enron, then each outstanding restricted stock award or option,
regardless of vesting, will be surrendered and canceled and each grantee will
receive a cash payment from Azurix. If there is a change in control of Azurix,
then each outstanding restricted stock award or option, regardless of vesting,
will be surrendered and canceled and each grantee will receive a cash payment
from Azurix. In either case, the cash payment for restricted stock awards will
equal the fair market value of a share of our common stock on the date of
cancellation multiplied by the number of shares subject to the restricted stock
award. In either case, the cash payment for canceled options will equal the
difference between the fair market value of a share of our common stock on the
date of cancellation minus the exercise price of the canceled options multiplied
by the number of shares covered by the canceled options. In the case of a change
in control of Azurix by means of a merger, sale or other business combination or
a tender offer, the fair market value of our common stock for purposes of the
calculation set forth in the previous sentence will be the per share price
offered to our stockholders in such transaction.

(1) These options are subject to vesting based on the following schedule:
    Rebecca P. Mark -- 25% per year over four years; Rodney L. Gray -- 20% per
    year over five years; Amanda K. Martin -- 25% per year over four years; Alex
    Kulpecz -- 20% per year over five years; and Colin F. Skellett -- 33 1/3%
    per year over three years.
    
 
   
(2) Each of these options was granted pursuant to our stock incentive plan and
    is subject to the terms of the stock incentive plan as described above.
    These options were granted at an exercise price equal to the fair value of
    our common stock as determined by our Board of Directors on the date of the
    grant.
    
 
   
(3) The 0%, 5% and 10% assumed annual rates of compounded stock price
    appreciation are mandated by the rules of the SEC. There can be no assurance
    that the actual stock price appreciation over the ten-year option term will
    be at the assumed 0%, 5% or 10% levels or at any other defined level. Unless
    the market price of the common stock appreciates over the option term, no
    value will be realized from the option grants. The potential realizable
    value is calculated by assuming that the fair market value of the common
    stock on the date of grant of the options appreciates at the indicated rate
    for the entire term of the option and that the option is exercised at the
    exercise price and sold on the last day at the appreciated price.
    
 
   
     In addition to the option grants to the Named Executive Officers in the
table above, Azurix granted options to purchase a total of 2,200,150 shares of
common stock at an exercise price of $16.72 per share to other employees with
vesting schedules generally providing for vesting over three to five years. All
of these options expire ten years after the grant date of February 2, 1999.
    
 
   
     In approving the grants described above, the Stock Plan Committee sought to
provide incentives in addition to compensation to Azurix's employees to devote
their utmost effort and skill to the advancement and betterment of Azurix by
providing such employees with an opportunity to participate in the ownership of
Azurix and thereby have an interest in the success and increased value of Azurix
as well as to enhance Azurix's ability to retain the services of its key
employees. As a member of the Stock Plan Committee, Rebecca P. Mark participated
in approving these grants, except with respect to the grant of options to
herself.

                              CERTAIN TRANSACTIONS
 
   
     In 1998, there were significant transactions among us, Enron, Atlantic
Water Trust and Marlin Water Trust. For purposes of governing these ongoing
relationships, we will enter into, or continue in effect, various agreements and
relationships, including those described below. Some of the agreements
summarized below will be included as exhibits to the registration statement of
which this prospectus is a part, and the following summaries are qualified
completely by reference to such exhibits which we incorporate in this prospectus
by reference.
    
 
   
     During 1998, Azurix indirectly acquired all of the outstanding ordinary
share capital of Wessex, and Enron contributed to Azurix the outstanding common
stock of a subsidiary that in June 1998 acquired a 32.1% ownership interest in
Obras Sanitarias Mendoza. In December 1998, Enron contributed Azurix to Atlantic
Water Trust and Marlin Water Trust acquired a 50% voting interest in Atlantic
Water Trust. Enron retained a 50% voting interest in Atlantic Water Trust.
    
 
   
     On February 25, 1999, in connection with the Cancun acquisition, Enron
advanced to Azurix $15.0 million, which was used by Azurix to fund a loan to
Cancun. On March 24, 1999, Enron paid on behalf of Azurix $13.5 million to fund
the Cancun acquisition which closed on that date.
    
 
   
     Enron currently provides office space to Azurix and various services such
as computer hardware and software and support services such as risk management,
accounts payable, payroll and information technology services. Costs are
allocated to Azurix based upon usage, or where no direct method can be
efficiently applied due to administrative burden, upon factors such as
annualized payroll or employee headcount. Employees, other than Wessex
employees, are covered by various employee benefit plans of Enron such as
retirement, stock option, medical, dental, life insurance and other benefit
plans. These costs are allocated to Azurix based upon Enron's costs of
administering and providing the benefit plans.
    
 
   
     Enron has paid on behalf of Azurix approximately $70 million to fund our
general, administrative and operating expenses, from our inception through April
30, 1999, in addition to certain capital expenditures. This includes $28.5
million advanced to us by Enron in connection with our investment in Cancun, as
well as advances relating to the services described above. The amount paid by
Enron is non-interest bearing and has no maturity date. We intend to use a
portion of the net proceeds that we receive from the offering to repay this
amount. See "Use of Proceeds."
    
 
   
ACQUISITION OF WESSEX
    
 
   
     On October 2, 1998, Azurix, through its indirect wholly owned subsidiary,
Azurix Europe, acquired over 90% of the outstanding ordinary share capital of
Wessex. On that same date, Azurix Europe issued notices to the remaining Wessex
ordinary shareholders, informing them that it intended to exercise its rights
under the English Companies Act to acquire compulsorily all of the outstanding
ordinary shares not held by Azurix Europe. The compulsory share acquisition was
completed in November 1998. The per share price paid to Wessex shareholders was
L6.30. The total cost of the Wessex acquisition, including transaction costs,
was $2.4 billion, plus the assumption of $481.5 million of existing Wessex debt.
The cost included cash consideration paid to Wessex shareholders, net of $1.7
million cash acquired, and the issuance of loan notes to Wessex shareholders in
the face amount of $119.8 million.
    
 
   
     The acquisition was financed through capital contributions from Enron Water
(Holding) L.L.C., formerly Azurix's parent company and a wholly owned subsidiary
of Enron, totaling $1.6 billion and the issuance of $0.8 billion in debt by
Azurix Europe. The financing of the Wessex acquisition by Azurix, through Azurix
Europe, was as follows:
    
 
   
     - Enron made a $500.2 million capital contribution to Enron Water (Holding)
       L.L.C.
    
 
   
     - Enron borrowed $1.1 billion under a revolving credit facility, which
       Enron loaned to Enron Water (Holding) L.L.C.
    
 
   
     - Enron Water (Holding) L.L.C. made a capital contribution of these funds
       to Azurix, and Azurix, through a wholly owned subsidiary, made a capital
       contribution of these funds to Azurix Europe
    
                                       82
<PAGE>   88
 
   
     - Enron lent L73 million ($124.4 million) to Azurix Europe under a senior
       loan agreement
    
 
   
     - Enron lent L72 million ($122.7 million) to Azurix Europe under a
       short-term, senior, unsecured credit facility, which loan, together with
       $2.1 million of accrued interest, was subsequently repaid with the
       proceeds from the sale of U.K. Waste in December 1998
    
 
   
     - Azurix Europe borrowed L252 million ($429.3 million) under the existing
       senior credit facility
    
 
   
     - Azurix Europe issued seven-year, senior, unsecured loan notes in the face
       amount of L70.5 million ($119.8 million) to Wessex shareholders who
       elected to take loan notes instead of cash
    
 
     In connection with regulatory clearance of the acquisition of Wessex, Enron
and Wessex's immediate parent, Azurix Europe, agreed to make certain
undertakings regarding the modification of Wessex Water Services' license as a
provider of water and wastewater services. The objective of the modifications
was to allow Wessex to operate as if it is a stand-alone organization and to
ensure that Wessex has sufficient financial and managerial resources.
 
   
ACQUISITION OF INTEREST IN ATLANTIC WATER TRUST
    
 
   
     In December 1998, Enron contributed Azurix to Atlantic Water Trust, a
Delaware business trust, by contributing Enron Water (Holding) L.L.C. and
merging it into Azurix. In connection with Enron's contribution, Marlin Water
Trust acquired for $1.149 billion a 50% voting interest in Atlantic Water Trust,
with Enron retaining a 50% voting interest. Of the $1.149 billion paid by Marlin
Water Trust, $900 million was used to repay a portion of the indebtedness
incurred by Enron and its affiliates in connection with the Wessex acquisition.
See "Principal and Selling Stockholders -- Atlantic Water Trust."
    
 
CONFLICTS OF INTEREST
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately      % of our outstanding common stock,   % if the underwriters'
over-allotment options are exercised in full. Each of Enron and Marlin Water
Trust owns a 50% voting interest in Atlantic Water Trust. To date, Enron has
appointed all of the directors of Atlantic Water Trust and Azurix, although
Marlin Water Trust at any time has the right to elect or replace half of the
directors of Atlantic Water Trust and currently up to half of the Azurix
directors. Following the offering, as long as Atlantic Water Trust owns a
majority of our outstanding common stock, Marlin Water Trust has the right to
direct Atlantic Water Trust to elect or replace a percentage of Azurix's
directors equal to 50% minus the percentage of outstanding common stock held by
persons other than Atlantic Water Trust. Furthermore, Marlin Water Trust, with
the consent of the holders of a majority of our outstanding common stock held by
persons other than Atlantic Water Trust, Enron and its affiliates, has the right
to direct Atlantic Water Trust to elect or replace half of Azurix's directors.
Enron has the right to direct Atlantic Water Trust to elect or replace the other
half of Azurix's directors. As a result, following the offering, Enron and
Marlin Water Trust will continue to exert significant influence over the
policies, management and affairs of Azurix and the outcome of most corporate
actions requiring stockholder approval, including the approval of transactions
involving a change in control of Azurix.
    
 
   
     Currently, a majority of our directors are also directors or officers of
Enron, a situation that may create conflicts of interest. The directors and
officers of Enron have fiduciary duties to manage Enron, including its
investments in subsidiaries and affiliates such as Azurix, in a manner
beneficial to Enron and its stockholders. Similarly, the directors and officers
of Azurix have fiduciary duties to manage Azurix in a manner beneficial to
Azurix and its stockholders. In some circumstances, the duties of these
directors and officers of Enron may conflict with their duties as directors of
Azurix. In addition, other conflicts of interest exist and may arise in the
future as a result of the extensive relationships between Enron and Azurix.
Enron and Azurix have agreed that conflicts of interest between Enron and Azurix
may be resolved through approval by a majority of the directors of Azurix not
associated with Enron. See "Principal and Selling Stockholders."

<PAGE>   89
 
   
AGREEMENT REGARDING BUSINESS OPPORTUNITIES AND RELATED MATTERS
    
 
   
     Enron and Azurix will enter into an agreement that will limit the scope of
Azurix's business and provide that Enron and its affiliates may engage in
water-related businesses, even if those activities have a competitive impact on
Azurix. In general, Enron will be permitted to engage in any business
whatsoever, including water, wastewater and other businesses competing with
Azurix, and may compete in public tenders against Azurix, provided the business
is conducted and opportunities are identified and developed through Enron's own
personnel and not through Azurix. If an opportunity in the water industry is
presented to a person who is an officer or director of both Enron and Azurix,
the opportunity must first be offered to Azurix, unless water constitutes a
minority of the fair market value of the opportunity, as determined by that
officer or director in good faith based on information available at the time.
    
 
   
     In the agreement, Azurix will acknowledge that Enron has fiduciary and
contractual obligations to other persons and entities under existing agreements
and relationships and has agreed that, in the event of a conflict between the
duties of Enron under the agreement and the duties of Enron to third parties
under agreements or relationships that exist on the date of execution of the
agreement, Enron will be entitled to perform its duties to such third parties
without any liability to Azurix.
    
 
   
     The agreement will provide that any standard of care, any duty of loyalty
and any other duty imposed by the agreement or under Delaware law or any other
applicable law, rule or regulation shall be modified, waived or limited as
required in order to permit Enron to act under the agreement and to make any
decision pursuant to the authority prescribed in the agreement so long as such
action is reasonably believed by Enron to be in, or not inconsistent with, the
agreement or the interests of Azurix. Azurix has agreed to indemnify Enron and
its officers, directors and employees against any claim that Enron's pursuit of
water business was a breach of any duty owed by Enron to Azurix, provided Enron
has followed the rules described above.
    
 
   
     Azurix's purpose clause permits it to engage in the businesses generally
identified in this prospectus, activities incidental to those businesses, and
such other businesses as Atlantic Water Trust may approve in its sole
discretion, or if Atlantic Water Trust ceases to control Azurix, then such other
businesses as Enron may approve in its sole discretion. Under the agreement,
Azurix will agree not to amend its certificate of incorporation to expand its
purpose clause without Atlantic Water Trust's prior written consent or, if
Atlantic Water Trust ceases to control Azurix, Enron's prior written consent.
    
 
   
     The agreement will restrict Enron and Azurix from taking action that might
cause either of them to violate any law or that would require either of them to
register as a public utility holding company under the Public Utility Holding
Company Act of 1935.
    
 
   
     The agreement will state that whenever a potential conflict of interest
exists or arises between Enron and Azurix any resolution or course of action in
respect of such conflict of interest shall be permitted and deemed approved, and
will not constitute a breach of any duty stated or implied by law or equity, if
the resolution or course of action is authorized by the agreement or, by
operation of the agreement, is deemed to be fair and reasonable to Azurix. The
agreement will state that any conflict of interest and any resolution of such
conflict of interest shall be conclusively deemed fair and reasonable to Azurix
if such conflict of interest or resolution is:
    
 
   
     - Approved by special approval (the approval by a majority of the directors
       of Azurix not associated with Enron)
    
 
   
     - On terms no less favorable to Azurix than those generally being provided
       to or available from unrelated third parties
    
 
   
     - Fair to Azurix, taking into account the totality of the relationships
       between the parties involved (including other transactions that may be
       particularly favorable or advantageous to Azurix)
    
 
   
     Enron may adopt a resolution or course of action that has not received
special approval. Enron and any person voting in connection with a special
approval will be authorized in connection with its
    
 
                                       84
<PAGE>   90
 
   
determination of what is "fair and reasonable" to Azurix and in connection with
its resolution of any conflict of interest to consider:
    
 
   
     - The relative interests of any party to such conflict, agreement,
       transaction or situation and the benefits and burdens relating to such
       interest
    
 
   
     - Any customary or accepted industry practices and any customary or
       historical dealings with a particular person
    
 
   
     - Any applicable generally accepted accounting or engineering practices or
       principles
    
 
   
     - Such additional factors as such person determines in its sole discretion
       to be relevant, reasonable or appropriate under the circumstances
    
 
   
     In the absence of bad faith by Enron, the resolution, action or terms so
made, taken or provided by Enron with respect to such matter shall not
constitute a breach of the agreement or a breach of any standard of care, any
duty of loyalty or any other duty imposed by the agreement or under Delaware law
or any other law, rule or regulation.
    
 
   
     Disputes under the agreement are to be resolved through arbitration. The
agreement will continue indefinitely, except that it will expire on the first
date on which both of the following occur:
    
 
   
     - Neither Enron nor Atlantic Water Trust directly or indirectly owns or has
       the power to vote at least 35% of the shares of Azurix ordinarily
       entitled to vote for the election of directors, and
    
 
   
     - Neither Enron nor Atlantic Water Trust otherwise controls Azurix.
    
 
   
     The mutual covenants and agreements in the agreement will be the
consideration given by each party to the other in support of the agreement. In
addition, the agreement will state that Enron's investment in Atlantic Water
Trust will be predicated on the execution and delivery of an agreement
containing substantially the terms set forth in the agreement.
    
 
   
SERVICES AGREEMENT
    
 
   
     We will have an agreement with Enron pursuant to which Enron will provide
various corporate staff and support services to us. These services include
information technology, building maintenance, security and other office services
as well as employee development, training and maintenance of compensation and
other benefits programs. We also may utilize Enron's regulatory affairs,
marketing affairs, treasury and risk assessment and control departments. In
addition, Azurix may continue to participate in Enron's corporate insurance
program. The agreement will provide that we may use the international offices of
Enron and its affiliates for projects, subject to our mutual agreement with
Enron or its affiliates on a project-by-project basis. The agreement will
provide that we will reimburse Enron for direct charges related to the Enron
services and facilities that we use. We will also be allocated an amount for
overhead charges related to Enron corporate staff and support services which we
utilize. This overhead charge will be allocated based upon factors such as
employee headcount, payroll and square footage. Our management believes the
allocation methods and costs are reasonable. We expect to incur costs for
services used under the agreement of approximately $15 million annually. Our
agreement with Enron is for an indefinite term, but either of us may terminate
the agreement on 180 days' notice.
    
 
   
CREDIT AGREEMENT
    
 
   
     We intend to enter into a credit agreement with Enron, whereby Enron will
provide funds to us for general, administrative and operating expenses. The
credit agreement will be effective May 1, 1999 and terminate December 15, 2001.
The total commitment under the credit agreement will be $180 million. Advances
under the facility will bear interest at the daily average one-month London
interbank offered rate plus 1.25%. Amounts borrowed under the credit agreement
may be prepaid, in full or in part, at any time during the term of the credit
agreement. Amounts prepaid may be re-borrowed during the term of
    
 
                                       85
<PAGE>   91
 
   
the credit agreement. The principal amount outstanding under the credit
agreement will be limited to no more than:
    
 
   
     - $60 million at any time during calendar year 1999
    
 
   
     - $120 million at any time during calendar year 2000
    
 
   
     - $180 million at any time during calendar year 2001
    
 
LICENSE AGREEMENT
 
   
     Enron will license to Azurix the non-exclusive right to use the phrase "an
Enron Company" and its logo in identifying Azurix as part of the Enron
enterprise for use in its businesses permitted under the business opportunities
agreement described above, so long as Enron or Atlantic Water Trust's ownership
of Azurix is at least 35% or otherwise as the parties may agree. The license is
royalty free, and Azurix bears any costs associated with its use under a related
cost sharing agreement. The license agreement is for a term of one year, and
renews automatically and repetitively for similar terms, unless terminated by
either party upon 30 days' notice or earlier upon uncured default. Following
termination, Azurix must phase out use of existing materials within 90 days.
    
 
   
REGISTRATION RIGHTS AGREEMENT
    
 
   
     We will enter into an agreement with Atlantic Water Trust, which will allow
Atlantic Water Trust to request us to register shares of our common stock owned
by Atlantic Water Trust. Atlantic Water Trust will have the right to request one
such registration per annum, plus one additional such registration. In addition,
Atlantic Water Trust will also have the right, which it may exercise at any
time, to include such shares in any registration of common stock made by us in
the future. We will agree to cooperate fully in connection with any such
registration and with any offering made under the registration rights agreement
and to pay all costs and expenses, other than underwriting discounts and
commissions, related to shares sold by Atlantic Water Trust in connection with
any such registration. The rights of Atlantic Water Trust under the registration
rights agreement will be transferable by Atlantic Water Trust. See "Risk
Factors -- Future Sales of our Common Stock May Depress our Stock Price" and
"Shares Eligible for Future Sale."

ATLANTIC WATER TRUST
 
   
     In December 1998, Enron contributed Azurix to Atlantic Water Trust, a
Delaware business trust. The principal purpose of Atlantic Water Trust is to own
equity interests in Azurix and to own Bristol Water Trust, and to engage in
other transactions related to the sale of an interest in Atlantic Water Trust to
Marlin Water Trust. In connection with Enron's contribution of Azurix to
Atlantic Water Trust, Marlin Water Trust acquired for $1.149 billion a 50%
voting interest in Atlantic Water Trust, with Enron retaining a 50% voting
interest. Marlin Water Trust financed the acquisition of its interest in
Atlantic Water Trust by issuing senior notes for $1.024 billion that mature
December 15, 2001, and issuing trust certificates for a total of $125 million.
Currently, five institutional investors and their affiliates hold the trust
certificates of Marlin Water Trust.
    
 
   
     Of the $1.149 billion paid by Marlin Water Trust, $900 million was used to
repay a portion of the indebtedness incurred by Enron affiliates in connection
with the acquisition of Wessex. The remaining $249 million was deposited in an
account established by Bristol Water Trust, a wholly owned subsidiary of
Atlantic Water Trust. The funds in this account should generate sufficient
liquidity to fund distributions from Atlantic Water Trust to Marlin Water Trust
that will provide Marlin Water Trust with sufficient funds to service interest
on the senior notes and provide a yield to the trust certificate holders at
least through 2001. Azurix is not required to make any distributions to Atlantic
Water Trust, including any of its proceeds from the offering. Additionally,
neither Azurix, nor any of its subsidiaries, has guaranteed any obligations of
Marlin Water Trust and no assets of Azurix, nor any of its subsidiaries, are
pledged as security for the senior notes of Marlin.
    
 
   
     Enron is entitled, with respect to distributions resulting from the sale of
Azurix stock by Atlantic Water Trust, to receive the first $180 million of
distributions by Atlantic Water Trust. After the receipt of $180 million by
Enron, further distributions resulting from the sale of Azurix stock by Atlantic
Water Trust and other non-liquidating distributions are generally to be paid
first to Marlin Water Trust until Marlin Water Trust has received funds equal to
the amount then in its trust account with the remainder to Enron. Liquidation
distributions by Atlantic Water Trust are generally to be paid to Enron and
Marlin Water Trust pro rata based on their then respective trust accounts.
    
 
   
     If Atlantic Water Trust fails by December 15, 2001 to make aggregate
distributions to Marlin Water Trust of amounts sufficient to repay the senior
notes of Marlin Water Trust, then Marlin Water Trust has the right to cause
Atlantic Water Trust to liquidate and sell its remaining shares of Azurix. In
order to prevent the liquidation of Atlantic Water Trust by Marlin Water Trust,
Enron has the right to contribute funds generated from Enron equity offerings to
Atlantic Water Trust in order to fund distributions to Marlin. In such event,
Enron's beneficial interest, but not voting interest, in Atlantic Water Trust
would increase and Marlin Water Trust's beneficial interest, but not voting
interest, in Atlantic Water Trust would decrease. Other actions, such as the
refinancing of the senior notes of Marlin Water Trust, might also be taken which
could eliminate the necessity of Atlantic Water Trust selling additional shares
of Azurix. However, Atlantic Water Trust may elect to sell, or be required to
sell, some or all of its remaining shares of Azurix in order to fund Marlin
Water Trust's obligations. The proceeds to Atlantic Water Trust from this
initial public offering are expected to be approximately $400 million, before
deducting underwriting discounts and commissions and estimated expenses and
assuming no exercise of the over-allotment options. After payment of
underwriting discounts and commissions and expenses, $180 million of these
proceeds will be distributed to Enron and the remainder will be distributed to
Marlin Water Trust. The proceeds distributed to Marlin Water Trust are expected
to be used to redeem a portion of the senior notes.
    
 
   
     Marlin Water Trust, or the trustee under its senior notes indenture, may
cause the liquidation of Atlantic Water Trust prior to December 15, 2001 if
specific events occur and the senior notes are not repaid from other sources.
These events include: (1) defaults under certain of Azurix's, Enron's or Marlin
Water Trust's debt obligations or (2) a downgrading of Enron senior debt to
below "Baa3" by Moody's Investors Service, Inc., "BBB-" by Standard & Poor's
Ratings Services or "BBB-" by Duff & Phelps

Credit Rating Co. and a decline in Enron's common stock price below $37.84. The
last sale price of Enron common stock, as reported by the New York Stock
Exchange, on May 4, 1999 was $76.19.
    
 
   
     Each of Marlin Water Trust and Enron has the right and power at all times
to appoint up to 50% of the members of the board of directors of Atlantic Water
Trust. Marlin Water Trust's certificateholders are entitled to exercise Marlin
Water Trust's appointment rights. If the Marlin Water Trust certificateholders
defer exercising their appointment rights, Enron has the right to appoint such
members, but Marlin Water Trust has the right, at any time, without cause, to
remove any such members. To date, Enron has appointed all of the directors of
Atlantic Water Trust.
    
 
     As long as Atlantic Water Trust owns a majority of our outstanding common
stock, Marlin Water Trust has the right to direct Atlantic Water Trust to elect
or replace a percentage of Azurix's directors equal to 50% minus the percentage
of outstanding common stock held by persons other than Atlantic Water Trust.
Furthermore, Marlin Water Trust, with the consent of the holders of a majority
of our outstanding common stock held by persons other than Atlantic Water Trust,
Enron and its affiliates, has the right to direct Atlantic Water Trust to elect
or replace half of Azurix's directors. Enron has the right to direct Atlantic
Water Trust to elect or replace the other half of Azurix's directors. In all
other circumstances, the board of directors of Atlantic Water Trust will direct
the voting of Atlantic Water Trust's Azurix shares. Under the terms of the
Atlantic Water Trust agreement, Enron can be prevented from appointing more than
half of Azurix's directors at any time.

                          DESCRIPTION OF CAPITAL STOCK
    
 
     The authorized capital stock of Azurix consists of 500,000,000 shares of
common stock, par value $0.01 per share, and 50,000,000 shares of preferred
stock, par value $0.01 per share. Prior to the offering, 100,000,000 shares of
common stock were outstanding. No shares of preferred stock have been issued.
 
   
     The following summarizes important provisions of our capital stock and
describes all material provisions of our certificate of incorporation and
bylaws. This summary is qualified by our certificate of incorporation and
bylaws, copies of which have been filed as exhibits to the registration
statement of which this prospectus is a part and by the provisions of applicable
law.
    
 
COMMON STOCK
 
     Following the offering,           shares of common stock will be issued and
outstanding. Holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Because holders of common stock do
not have cumulative voting rights, the holders of a majority of the shares of
common stock can elect all of the members of the board of directors standing for
election. Subject to preferences of any preferred stock that may be issued in
the future, the holders of common stock are entitled to receive such dividends
as may be declared by the board of directors. The common stock is entitled to
receive pro rata all of the assets of Azurix available for distribution to its
stockholders. There are no redemption or sinking fund provisions applicable to
the common stock. All outstanding shares of common stock are fully paid and
non-assessable.
 
PREFERRED STOCK
 
     Subject to the provisions of the certificate of incorporation and
limitations prescribed by law, the board of directors has the authority to issue
up to 50,000,000 shares of preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions thereof, including dividend
rights, dividend rates, conversion rates, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
any series or the designation of such series, which may be superior to those of
the common stock, without further vote or action by the stockholders. There will
be no shares of preferred stock outstanding upon the closing of the offering and
Azurix has no present plans to issue any preferred stock.
 
     One of the effects of undesignated preferred stock may be to enable the
board of directors to render more difficult or to discourage an attempt to
obtain control of Azurix by means of a tender offer, proxy contest, merger or
otherwise, and thereby to protect the continuity of Azurix's management. The
issuance of shares of the preferred stock pursuant to the board of directors'
authority described above may adversely affect the rights of the holders of
common stock. For example, preferred stock issued by Azurix may rank prior to
the common stock as to dividend rights, liquidation preference or both, may have
full or limited voting rights and may be convertible into shares of common
stock. Accordingly, the issuance of shares of preferred stock may discourage
bids for the common stock or may otherwise adversely affect the market price of
the common stock.
 
   
DESCRIPTION OF PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS
    
 
  CLASSIFIED BOARD OF DIRECTORS AND LIMITATIONS ON REMOVAL OF DIRECTORS
 
     Our board of directors is divided into three classes. The directors of each
class are elected for three-year terms, with the terms of the three classes
staggered so that directors from a single class are elected at each annual
meeting of the stockholders. Until such time, called the "Trigger Date," as
neither Atlantic Water Trust nor Enron together with its subsidiaries owns a
majority of the outstanding voting stock of Azurix, the holders of a majority of
our outstanding voting stock may remove a director with or without cause.
Thereafter, stockholders may remove a director only for cause and to do so, at
least 66 2/3% of the voting power of the outstanding shares of common stock must
vote for removal. In general, after the
 
                                       90
<PAGE>   96
 
Trigger Date the board of directors, not the stockholders, will have the right
to appoint persons to fill vacancies on the board of directors.
 
   
  WRITTEN CONSENT OF STOCKHOLDERS
    
 
   
     Our certificate of incorporation provides that prior to the Trigger Date
any action required or permitted to be taken by our stockholders may be taken at
a duly called meeting of stockholders or by written consent of stockholders
owning the minimum number of shares required to approve such action. After such
time, any action by our stockholders must be taken at an annual or special
meeting of stockholders. Special meetings of the stockholders may be called only
by the board of directors. These provisions could have the effect of deterring
hostile takeovers or delaying changes in control.
    
 
  BUSINESS COMBINATIONS UNDER DELAWARE LAW
 
   
     Under the terms of our certificate of incorporation we have "opted-out" of
Delaware's anti-takeover law. In general, Section 203 of the Delaware corporate
law provides that certain persons who, together with affiliates and associates
owns, or within three years did own, 15% or more of the outstanding voting stock
of a corporation may not engage in certain business combinations with the
corporation for a period of three years after the date on which the person
became an interested stockholder. Section 203 does not include interested
stockholders prior to the time our common stock is listed on the NYSE. This
includes Atlantic Water Trust and Enron. Section 203 defines the term "business
combination" to encompass a wide variety of transactions with or caused by an
interested stockholder including mergers, asset sales and other transactions in
which the interested stockholder receives or could receive a benefit on other
than a pro rata basis with other stockholders. The existence of this provision
would have an anti-takeover effect with respect to transactions not approved in
advance by our Board of Directors, including discouraging takeover attempts that
might result in a premium over the market price for the shares of our common
stock.
    
 
  ADVANCE NOTICE PROCEDURE FOR STOCKHOLDER PROPOSALS
 
   
     Our bylaws establish an advance notice procedure for the nomination of
candidates for election as directors as well as for stockholder proposals to be
considered at annual meetings of stockholders. In general, notice of intent to
nominate a director must be delivered to or mailed and received at our principal
executive offices as follows:
    
 
   
     - With respect to an election to be held at the annual meeting of
       stockholders, 120 days prior to the anniversary date of the proxy
       statement for the immediately preceding annual meeting of stockholders.
    
 
   
     - With respect to an election to be held at a special meeting of
       stockholders for the election of directors, not later than the close of
       business of the 10th day following the day on which such notice of the
       date of the meeting was mailed or public disclosure of the date of the
       meeting was made, whichever first occurs, and must contain specified
       information concerning the person to be nominated. Notice of
       stockholders' intent to raise business at an annual meeting must be
       delivered to or mailed and received at our principal executive offices
       not less than 120 days prior to the anniversary date of the proxy
       statement for the preceding annual meeting of stockholders. These
       procedures may operate to limit the ability of stockholders to bring
       business before a stockholders meeting, including with respect to the
       nomination of directors of considering any transaction that could result
       in a change of control. These advance notice procedures are not
       applicable prior to the Trigger Date.
    
 
                                       91
<PAGE>   97
 
  LIMITATION OF LIABILITY OF OFFICERS AND DIRECTORS
 
   
     Our certificate of incorporation provides that no director shall be
personally liable to Azurix or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability as follows:
    
 
   
     - For any breach of the director's duty of loyalty to Azurix or its
       stockholders
    
 
   
     - For acts or omissions not in good faith or which involve intentional
       misconduct or knowing violation of laws
    
 
   
     - For unlawful payment of a dividend or unlawful stock purchase or stock
       redemption
    
 
   
     - For any transaction from which the director derived an improper personal
       benefit
    
 
   
     The effect of these provisions is to eliminate the rights of Azurix and its
stockholders, through stockholders' derivative suits on behalf of Azurix, to
recover monetary damages against a director for breach of fiduciary duty as a
director, including breaches resulting from grossly negligent behavior, except
in the situations described above. These provisions will not change after the
Trigger Date.

                          DESCRIPTION OF INDEBTEDNESS
 
   
INDEBTEDNESS OF AZURIX
    
 
   
     Enron has funded on behalf of Azurix approximately $70 million to fund our
general, administrative and operating expenses, from our inception through April
30, 1999, in addition to certain capital expenditures. This includes $28.5
million advanced to us by Enron to fund our acquisition of and loan to our
acquisition in Cancun. The amount due to Enron is non-interest bearing and has
no maturity date. We intend to use a portion of the net proceeds that we receive
from the offering to repay these amounts. See "Use of Proceeds."
    
 
   
     We intend to enter into a credit agreement with Enron, whereby Enron will
provide funds to us for general, administrative and operating expenses. The
credit agreement will be effective May 1, 1999 and terminate December 15, 2001.
The total commitment under the credit agreement will be $180 million. Advances
under the facility will bear interest at the daily average one-month London
interbank offered rate plus 1.25%. Amounts borrowed under the facility may be
prepaid, in full or in part, at any time during the term of the agreement.
Amounts prepaid may be re-borrowed during the term of the facility. Principal
amount outstanding under the facility will be limited to no more than:
    
 
   
     - $60 million at anytime during calendar year 1999
    
 
   
     - $120 million at anytime during calendar year 2000
    
 
   
     - $180 million at anytime during calendar year 2001
    
 
INDEBTEDNESS OF AZURIX EUROPE LTD.
 
   
  EXISTING SENIOR CREDIT FACILITY
    
 
   
     Azurix Europe, an indirect, wholly owned subsidiary of Azurix and the
holding company for Wessex, has an existing senior credit facility with a group
of banks. The existing senior credit facility is currently in the process of
being refinanced with a new senior credit facility described below. The existing
senior credit facility was initially entered into on August 18, 1998 with
Greenwich NatWest and Barclays Capital, as arrangers, and National Westminster
Bank PLC, as agent. The existing senior credit facility consists of a term loan
facility of L194 ($313.1) million. Amounts outstanding under the existing senior
credit facility bear interest at a rate based on the London interbank offered
rate plus a margin. As of April 30, 1999, L42 ($67.8) million in principal was
outstanding under the term loan facility.
    
 
   
     Loans made under the term loan facility were used to finance the
acquisition of Wessex. Loans made under the revolving credit facility may be
used to refinance Wessex's credit facilities or for general corporate purposes
up to L60 ($96.8) million outstanding at any time.
    
 
   
     Azurix Europe is required to repay L120 ($193.7) million of term loans by
July 24, 2000 and to repay any remaining outstanding amount under the term loan
by July 24, 2003. Generally, amounts repaid under the revolving credit facility
may be re-borrowed. The existing senior credit facility is a secured facility,
and Azurix Europe has pledged all its existing assets, including all the
ordinary shares of Wessex.
    
 
   
     CERTAIN COVENANTS. Azurix Europe and its subsidiaries have agreed not to
create or permit to exist any other security interest on any of their assets.
Azurix Europe will not sell, transfer or otherwise dispose of any of the
ordinary shares of Wessex. No borrower under the existing senior credit facility
will sell, transfer, grant or lease or otherwise dispose of all or any part of
its assets. Arm's length disposals are allowed. Azurix Europe will not make any
substantial change to the general nature or scope of its business as a water and
wastewater company in the United Kingdom. Azurix Europe will only conduct
business as a holding company. No borrower under the existing senior credit
facility will enter into any amalgamation, demerger, merger or reconstruction.
No borrower will acquire any assets or business or make any investment if the
assets, business or investment is substantial in relation to Azurix Europe.
Azurix Europe may not declare, recommend, make or pay any dividend, distribution
or payment to any of its shareholders or make any payment in respect of any
subordinated debt until after August 18, 1999 but only as long as
    
 
                                       93
<PAGE>   99
 
   
no default under the existing senior credit facility is then outstanding or will
result from the relevant dividend, distribution or payment and the ratio of
consolidated EBITDA, as defined in the existing senior credit facility, to
consolidated total interest payable is not less than 2.75:1 as of the latest
date on which that ratio has been tested. The existing senior credit facility
also places certain restrictions on the aggregate borrowings plus liabilities
for borrowings of Wessex that Azurix Europe and its subsidiaries may have
outstanding at any time. In addition, the existing senior credit facility
requires that while any acquisition loan notes, as described below, are
outstanding, there must be undrawn capacity under the term loan facility at
least equal to 95% of the aggregate principal amount of acquisition loan notes
outstanding.
    
 
     FINANCIAL COVENANTS. Azurix Europe is required to maintain the following
financial ratios on a quarterly and annual basis (1) the ratio of consolidated
EBITDA to consolidated net interest payable will be no less than 2.5:1 and (2)
the ratio of debt to total capitalization will not, as of each date on which it
is tested, exceed 50%.
 
   
     DEFAULT. Each of the following events is an event of default under the
existing senior credit facility:
    
 
     - A borrower not paying any amount which is due and payable by it within
       three business days after notice of non-payment
 
   
     - Azurix Europe failing to comply with its covenants, or a borrower not
       complying with any provision of a finance document or a representation,
       warranty or statement made or repeated in any finance document being
       materially incorrect and not remedied within 28 days
    
 
   
     - A cross-default related to any financial indebtedness of Azurix Europe or
       its subsidiaries occurring, including when the aggregate amount of
       financial indebtedness is less than L15 ($24.2) million
    
 
   
     - Events of insolvency or bankruptcy of a borrower or a material subsidiary
       occurring
    
 
   
     - Any attachment, or execution affecting any assets of a borrower or a
       material subsidiary having an aggregate value of L15 ($24.2) million that
       is not discharged within 14 days
    
 
     - The legal and beneficial ownership of the ordinary share capital of
       Azurix Europe held by Enron being less than 20%, and any bank, insurance
       company, investment or pension fund or other financial investor owning,
       directly or indirectly, or any other person owning, whether directly or
       indirectly, more of the legal and beneficial ownership of Azurix Europe
       than Enron
 
     - At any time less than 50% of the directors of Azurix Europe are also
       directors or senior officers of Enron or any significant operating
       subsidiary of Enron
 
     - At any time, any person or persons other than Enron acting in concert
       acquiring control of Azurix Europe
 
   
     - Wessex's license as a water and wastewater company being revoked or
       surrendered or ceasing to be held by Wessex Water Ltd or a wholly owned
       subsidiary of Wessex Water Ltd or Azurix Europe
    
 
     - Wessex's license or the rights or obligations under the license being
       materially modified in any manner that, in the reasonable opinion of a
       majority in interest of the lenders, has a material adverse effect on
       Azurix Europe
 
     - Any event or series of events occurring that, in the reasonable opinion
       of a majority in interest of the lenders, has a material adverse effect
       on the ability of the borrowers or Azurix Europe to perform their or its
       payment obligations under the finance documents
 
   
  NEW SENIOR CREDIT FACILITY
    
 
   
     Azurix Europe is currently negotiating with a group of banks for a new
senior credit facility which will replace and refinance outstanding amounts
under the existing senior credit facility. The new senior credit facility is
expected to be entered into in May 1999 with Chase Manhattan Plc and
Westdeutsche Landesbank Girozentrale, as arrangers, Westdeutsche Landesbank
Girozentrale as facility agent and Chase Manhattan Trustees Limited as security
agent. The new senior credit facility will consist of a revolving
    
                                       94
<PAGE>   100
 
   
credit facility of L425 ($686.0) million. Amounts outstanding under the new
senior credit facility will bear interest at a rate based on the London
interbank offered rate, plus a margin. If loans outstanding at the time of a new
loan are less than 50% of the total commitment of the facility, then the margin
applied to the new loan will equal 0.75% per annum. If loans outstanding at the
time of a new loan are greater than or equal to 50% of the total commitment of
the facility, then the margin applied to the new loan will equal 1.00% per
annum. Azurix Europe will pay a commitment fee on the undrawn, uncancelled
amount of the facility at the rate of 0.375% per annum. The facility will be for
a period of three years.
    
 
   
     It is expected that loans made under the facility will be used to refinance
Azurix Europe's existing indebtedness and may be used further to refinance any
outstanding debt of Azurix Europe and to make loans to affiliates of Azurix
Europe for the purpose of financing acquisitions of and investments in water and
wastewater assets and businesses, including the pending $107 million acquisition
of Philip Utilities. It is intended that of the L425 ($686.0) million facility
amount, L185 ($298.6) million could be used to refinance existing debt of Azurix
Europe and up to L240 ($387.4) million may be lent to affiliates. Intercompany
loans made under the facility will be senior obligations, maturing on or before
the maturity date of the facility, and, if practicable at interest rates at
least equal to the interest rates on the facility. The loans will be guaranteed
by Azurix in favor of Azurix Europe. The affiliates will be direct or indirect
wholly owned subsidiaries of Azurix which have been created as special purpose
vehicles. The facility will be a secured facility, and Azurix Europe will pledge
all its existing assets, including all the ordinary shares of Wessex.
    
 
   
     COVENANTS. Azurix Europe will agree that it will not, and will ensure that
its subsidiaries will not, create or permit to exist any other security interest
on any of their assets, except in the ordinary course of business, to secure
project finance indebtedness or other security interests in an aggregate amount
not to exceed L35 ($56.5) million. Azurix Europe will not sell, transfer or
otherwise dispose of any of the ordinary shares of Wessex. Azurix Europe will
also agree that it will not, and will ensure that its subsidiaries will not,
sell, transfer, grant or lease or otherwise dispose of all or any part of its
assets, except in the ordinary course of business or other disposals in an
aggregate amount not to exceed L35 ($56.5) million. Azurix Europe will not make
any substantial change to the general nature or scope of its business as a water
and wastewater company in the United Kingdom. Azurix Europe will only conduct
business as a holding company. Azurix Europe will agree that it will not, and
will ensure that its subsidiaries will not, enter into any amalgamation,
demerger, merger or reconstruction. Azurix Europe will agree that it will not,
and will ensure that its subsidiaries will not, acquire any assets or business
or make any investment if the assets, business or investment is substantial in
relation to Azurix Europe and its group, except in the ordinary course of
business, as a required capital expenditure or other acquisitions in an
aggregate amount not to exceed L10 ($16.1) million. Azurix Europe may not
declare, recommend, make or pay any dividend, distribution or payment to any of
its shareholders and will covenant to ensure that Wessex Water Services will
dividend to Wessex the maximum distribution permissible by the dividend policy,
from time to time, of Wessex Water Services and Wessex will dividend to Azurix
Europe its maximum distributable reserves from time to time. The facility also
will require that the aggregate borrowings plus liabilities for borrowings of
Wessex that Azurix Europe and its subsidiaries may have outstanding at any time
do not exceed L1,050 ($1,694.7) million. All excess cash flow of Azurix Europe
(i.e., all cash flow after deducting interest, taxes and operating expenses)
will be paid into a debt service reserve account. All excess cash flow will be
applied to build up, within six months of closing of the facility, an amount
determined by the security agent to be one year's gross interest payable under
the facility. All amounts credited to the debt service reserve account may be
invested in cash and cash equivalents with minimum credit ratings and, provided
credit enhancement is provided, may be lent by Azurix Europe to certain other
entities, including Azurix and Enron.
    
 
   
     FINANCIAL COVENANTS. Azurix Europe will be required to maintain, or ensure
Wessex maintains, the following financial ratios on a quarterly and annual
basis:
    
 
   
     - The ratio of consolidated EBITDA to consolidated net interest payable
       will be no less than, in the case of Azurix Europe, 2.25:1 and, in the
       case of Wessex, 2.5:1
    
 
                                       95
<PAGE>   101
 
   
     - The ratio of debt to total capitalization will not, as of each date on
       which it is tested, exceed, in the case of Azurix Europe, 50% and, in the

     - Any event or series of events occurring that, in the reasonable opinion
       of a majority in interest of the lenders, has a material adverse effect
       on the ability of Azurix Europe to perform its payment obligations under
       the finance documents
    
 
  ACQUISITION LOAN NOTES
 
   
     In connection with the acquisition of Wessex, Azurix Europe issued U.K.
pound denominated loan notes in a principal amount of L70.5 ($113.8) million to
Wessex shareholders in lieu of cash consideration for the ordinary shares of
Wessex. As of April 30, 1999, L70.5 ($113.8) million principal amount of
acquisition loan notes were outstanding. The acquisition loan notes are
redeemable, at the option of the holder, semiannually beginning September 30,
1999 and ending on September 30, 2005 when the acquisition loan notes mature.
Interest on the acquisition loan notes accrues at the London interbank offered
rate and is payable semiannually. The interest rate for the period the
acquisition loan notes were outstanding during 1998 was 7.125%. Holders of
acquisition loan notes can require a redemption of their notes at par plus
accrued interest in certain insolvency situations and if any principal or
interest payment is not paid within 30 days of its due date.

INDEBTEDNESS OF WESSEX
 
   
  BANK FACILITIES
    
 
   
     Wessex Water Services is a borrower under bank facilities with three major
banks that provide an aggregate of L75 ($121.1) million of availability for
general corporate purposes. As of April 30, 1999, L75 ($121.1) million was
outstanding under these bank facilities. These bank facilities were entered into
on April 1, 1999 and mature in April 2002. Loans under these credit facilities
accrue interest at the London interbank offered rate plus a margin of 0.275% per
annum. Each of these credit facilities requires Wessex Water Services to pay an
annual commitment fee equal to 0.15% of the available amount of the facility.
    
 
   
     Each of these facilities requires Wessex Water Services to maintain a ratio
in excess of 2:1 of earnings before interest received, interest costs,
exceptional charges and tax to interest costs less interest received. Wessex
Water Services is currently in compliance with this covenant. Each of these
facilities provides that each of the following will be an event of default:
    
 
   
     - Wessex Water Services failing to pay any amount due and payable under the
       facility on its due date
    
 
   
     - Wessex Water Services failing to comply with any other obligation under
       the facility, unless remedied within 30 days of the breach
    
 
   
     - Wessex Water Services providing the bank with materially inaccurate
       information
    
 
   
     - Wessex Water Services defaulting under any borrowing, where the
       outstanding amount exceeds L15 million, such that prepayment of such
       borrowing is required
    
 
   
     - Wessex Water Services losing its license as the water and wastewater
       services provider over a portion of its geographical region such that it
       would lose 15% or more of its revenues
    
 
   
     - Wessex Water Services ceasing to be a subsidiary of Azurix
    
 
   
     In addition, as of April 30, 1999, L24 ($38.7) million was outstanding
under uncommitted credit facilities.
    
 
   
  EUROPEAN INVESTMENT BANK LOANS
    
 
   
     Wessex Water Services is a borrower under facilities provided by the
European Investment Bank for purposes of financing its capital investment
program. These facilities currently consist of two separate loans with an
aggregate principal balance outstanding as of April 30, 1999 of L41.3 ($66.7)
million, including the effect of currency swap contracts in place as follows:
    
 
   
          (1) a U.S. dollar denominated floating rate loan of $49.9 million
     repayable in full in October 2001, and
    
 
   
          (2) a 25.0 billion Italian lire ($29.7 million) fixed rate loan
     repayable in ten semiannual installments through June 2002.
    
 
     Wessex guarantees the obligations of Wessex Water Services under these
facilities.
 
   
     The U.S. dollar dominated loan bears interest at London interbank offered
rate less 0.25% per annum. The Italian lire loan bears interest at 11.6%. Each
of these facilities requires Wessex to maintain the following financial
covenants:
    
 
   
     - Consolidated net borrowings will not exceed 150% of consolidated net
       tangible worth
    
 
   
     - Operating profits will be at least 2.0x total interest expense on an
       annual basis
    
 
   
     - Consolidated net tangible worth will be at least L400 million
    
 
                                       98
<PAGE>   104
 
   
     In each of these facilities, Wessex Water Services has agreed that it will
not carry on any business other than the business of providing water and
wastewater services in the area covered by its license and any ancillary
activity. An event of default will occur under each facility, allowing the bank
to require immediate payment, in the following instances:
    
 
   
     - If Wessex Water Services or Wessex is bankrupt or insolvent
    
 
   
     - If Wessex Water Services ceases to be a subsidiary of Wessex
    
 
   
     - If Wessex Water Services loses its license as the water and wastewater
       services provider over a portion of its geographical region such that it
       would lose 15% or more of its revenues
    
 
   
  FINANCE LEASE AGREEMENT
    
 
   
     Wessex Water Services is the lessee under a finance lease agreement with
Barclays Mercantile Business Finance Limited pursuant to which L59.7 ($96.4)
million of capital lease obligations (excluding interest on such obligations)
were outstanding as of April 30, 1999. Under the lease agreement, Wessex Water
Services is reimbursed by Barclays for the acquisition cost of machinery and
equipment acquired in connection with its capital expenditure program. Wessex
Water Services then makes periodic rental payments to Barclays. Payments are
made in installments payable semiannually through September 2002. Barclays has a
lien on the property that has been acquired in connection with the leases.
    
 
   
     The leasing of the equipment may be terminated at any time in the following
instances:
    
 
   
     - Wessex Water Services defaults in making any rental payment
    
 
   
     - Wessex Water Services or Wessex is bankrupt or insolvent
    
 
   
     - Wessex Water Services sells or mortgages or agrees to sell or mortgage
       any of the equipment or otherwise prejudices Barclays' ownership of, and
       rights with respect to, the equipment
    
 
   
     - Wessex Water Services fails to maintain adequate liability and property
       insurance
    
 
   
     - Wessex Water Services or Wessex defaults under any other debt agreement,
       where the outstanding amount exceeds L5 million, such that repayment of
       such debt is required
    
 
   
     - Wessex ceases to own a majority of the capital stock of Wessex Water
       Services
    
 
   
     - A material adverse change occurs to Wessex Water Services which
       substantially impairs its ability to perform its obligations under the
       lease agreement
    
 
   
     Wessex guarantees the obligations of Wessex Water Services under the lease
agreement. As guarantor, Wessex has agreed to maintain the same financial
covenants as required by the European Investment Bank facilities described
above.
    
 
   
  SENIOR UNSECURED BONDS
    
 
   
     On March 30, 1999, Wessex Water Services issued L300 ($484.2) million
principal amount of 10-year senior unsecured bonds bearing interest at 5.875%
per annum through its wholly owned subsidiary, Wessex Water Services Finance
Plc. Wessex Water Services has unconditionally and irrevocably guaranteed
payment of principal and interest of the bonds. All principal will be due on
March 30, 2009. Wessex Water Services used most of the proceeds from the sale of
the bonds to repay all outstanding amounts under its former bank credit
facilities as well as all outstanding amounts under uncommitted credit
facilities. Any remaining proceeds will be used for general corporate purposes.
    
 
   
     The bonds will be redeemed by Wessex Water Services as follows:
    
 
   
     - On March 30, 2009 at their principal amount
    
 
                                       99
<PAGE>   105
 
   
     - At the option of Wessex Water Services, if it becomes obligated to pay
       additional amounts because of a change in law, at their principal amount
    
 
   
     - At the option of Wessex Water Services, in whole or in part, at the
       higher of the following:
    
 
   
        -- their principal amount; or
    
 
   
        -- a redemption price, which is calculated based on the published
           redemption yield for a reasonably equivalent U.K. Government issued
           security with similar maturity and coupon.
    
 
   
     Bondholders have the right to require Wessex to buy back their bonds prior
to maturity at a price equal to the principal amount of the bond plus all
accrued but unpaid interest in the following instances:
    
 
     - Wessex's license as a water and wastewater company is terminated
 
     - Wessex Water Services Finance Plc ceases to be a subsidiary of Wessex
       Water Services
 
   
     - Material changes occur to the rights or benefits of Wessex's license or
       legislation is enacted which materially changes the duties or powers of
       the Secretary of State for the Environment or the Director General of
       Water Services and the rating on the bonds is downgraded below investment
       grade
    
 
   
     In addition, the bonds could become immediately due and payable if an event
of default occurs. These events include a cross-default by Wessex Water Services
or its subsidiaries under other debt instruments and events of insolvency.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of our common stock in the
public market could adversely affect the market price of our common stock. After
this offering is completed, the number of shares available for future sale into
the public markets will be subject to legal and contractual restrictions, some
of which are described below. The lapsing of these restrictions will permit
sales of substantial amounts of our common stock in the public market or could
create the perception that such sales could occur, which could adversely affect
the market price for our common stock. These factors could also make it more
difficult to raise funds through future offerings of common stock.
    
 
   
     Upon the completion of this offering, we will have           shares of our
common stock outstanding. Of these shares, the           shares sold in this
offering will be freely transferable and may be sold without restriction or
further registration under the Securities Act, except for any shares acquired by
an "affiliate" of Azurix as defined in Rule 144 under the Securities Act. The
remaining           shares of common stock outstanding and owned by the selling
stockholder will be "restricted securities," as that term is defined in Rule
144, and may be sold in the future without registration under the Securities Act
to the extent permitted by Rule 144, as described below, or any applicable
exemption under the Securities Act. In addition, shares owned by Atlantic Water
Trust or its transferee may be registered for sale under the Securities Act of
1933 under the terms of its registration rights agreement with us. See "Certain
Transactions -- Registration Rights Agreement" for more information regarding
these registration rights.
    
 
   
RULE 144
    
 
   
     In general, under Rule 144, as currently in effect, a person, or persons
whose shares are aggregated, including an affiliate, who has beneficially owned
"restricted securities" for at least one year would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of:
    
 
   
     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately           shares immediately after the offering; or
    
 
   
     - The average weekly trading volume of the common stock on the New York
       Stock Exchange during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale with the SEC.
    
 
   
     Sales under Rule 144 are also subject to certain other requirements
regarding the manner of sale, notice and availability of current public
information about Azurix.
    
 
   
     Since Atlantic Water Trust, the selling stockholder, is likely an
"affiliate" of us, subject to its exercise of registration rights described
under "Certain Transactions," the Rule 144 restrictions and requirements would
be applicable to shares of Azurix owned by them for so long as the selling
stockholder retains affiliate status.
    
 
   
RULE 144(k)
    
 
   
     Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an "affiliate", is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.
    
 
   
LOCK-UP AGREEMENTS
    
 
   
     In connection with the offering, we and the selling stockholder have
agreed, with certain exceptions, not to directly or indirectly engage in the
following activities for a period of 180 days after the date of this prospectus
without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith
Incorporated:
    
 
                                       101
<PAGE>   107
 
   
     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of common stock or securities convertible into or
       exchangeable or exercisable for or repayable with common stock, whether
       now owned or thereafter acquired by the person executing the agreement or
       with respect to which the person executing the agreement thereafter
       acquires the power of disposition, or file a registration statement under
       the Securities Act relating to any shares of common stock
    
 
   
     - Enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of common stock whether any
       such swap or transaction is to be settled by delivery of common stock or
       other securities, in cash or otherwise, see "Underwriting -- No Sales of
       Similar Securities"
    
 
   
     As an exception to these restrictions, we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors -- Future sales of our common stock
may depress our stock price."
    
 
   
STOCK PLAN
    
 
     After the offering, we intend to file a registration statement covering the
sale of approximately 7.8 million shares of common stock reserved for issuance
under our stock plan.
 
   
     Upon expiration of the lock-up period, these shares may be sold at any time
subject to compliance with the volume limitations and other restrictions of Rule
144. Options to purchase approximately 7.8 million shares of common stock will
also be outstanding after the offering. Such options generally provide for
incremental vesting over a three to five year period. In addition, more options
may be granted in the future. See "Management -- Stock Plan."

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES
                  TO NON-UNITED STATES HOLDERS OF COMMON STOCK
 
     The following is a summary of material U.S. federal income and estate tax
consequences expected to result under current law from the purchase, ownership
and taxable disposition of common stock by non-U.S. holders of common stock. A
"non-U.S. holder" is any person or entity other than:
 
     - A citizen or resident of the United States
 
     - A corporation, partnership or other entity created or organized in or
       under the laws of the United States or any state thereof
 
     - An estate, the income of which is includable in gross income for U.S.
       federal income tax purposes regardless of its source
 
     - A trust whose administration is subject to the primary supervision of a
       United States court and which has one or more U.S. persons who have the
       authority to control all substantial decisions of the trust
 
   
     This summary does not address all of the U.S. federal income and estate tax
considerations that may be relevant to non-U.S. holders in light of their
particular circumstances or to non-U.S. holders that may be subject to special
treatment under United States federal income tax laws. This summary does not
discuss any aspect of state, local or foreign taxation. This summary is based on
current provisions of the Internal Revenue Code of 1986, as amended, Treasury
regulations, judicial opinions, published positions of the U.S. Internal Revenue
Service and other applicable authorities, all of which are subject to change,
possibly with retroactive effect. In this prospectus, the Internal Revenue Code
of 1986, as amended, is called the "Code." Prospective purchasers of common
stock are advised to consult their tax advisors regarding the U.S. federal,
state and local, and non-U.S. income and other tax consequences of acquiring,
holding and disposing of common stock.
    
 
DIVIDENDS
 
     Azurix does not currently anticipate paying any dividends. Any dividends
paid to a non-U.S. holder on shares of common stock will be subject to
withholding of U.S. federal income tax at a rate of 30%, unless a lower rate is
prescribed under an applicable tax treaty. U.S. federal income tax withholding
will not be required, however, if the dividends are effectively connected with
the conduct of a trade or business of the non-U.S. holder within the United
States or, in the case of an applicable tax treaty, are attributable to a U.S.
permanent establishment maintained by the non-U.S. holder. Dividends that are
effectively connected with the conduct of a trade or business within the United
States, or are attributable to a U.S. permanent establishment will be subject to
U.S. federal income tax on a net income basis which is not collected by
withholding provided the non-U.S. holder files the appropriate certification
with Azurix or its agent. Any dividends received by a foreign corporation that
are effectively connected with the conduct of a trade or business within the
United States may also be subject to a "branch profits tax" at a rate of 30% or
such lower rate as may be specified by an applicable tax treaty.
 
     For purposes of the withholding tax rules discussed above and for purposes
of determining the applicability of a tax treaty rate under current U.S.
Treasury Regulations, dividends paid to an address outside the United States
will be presumed to be paid to a resident of the country of address, unless the
payor has knowledge to the contrary. Under recently issued U.S. Treasury
Regulations (referred to as "final regulations") that are effective for payments
made after December 31, 1999, a non-U.S. holder of common stock who wishes to
claim the benefit of a tax treaty rate would be required to satisfy applicable
 
                                       103
<PAGE>   109
 
certification and other requirements. In addition, under the final regulations,
in the case of common stock held by a foreign partnership:
 
     - The certification requirement generally would be applied to the partners
       of the partnership.
 
     - The partnership would be required to provide certain information,
       including a U.S. taxpayer identification number.
 
     A non-U.S. holder of common stock that is eligible for a reduced rate of
U.S. federal income tax withholding pursuant to a tax treaty may obtain a refund
of any excess amounts currently withheld by filing an appropriate claim for
refund with the Internal Revenue Service.
 
SALE OR DISPOSITION OF COMMON STOCK
 
     A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of any gain recognized on the sale or other taxable disposition of
common stock so long as:
 
     - The gain is not effectively connected with the conduct of a trade or
       business of the non-U.S. holder within the United States nor under an
       applicable tax treaty, is attributable to a U.S. permanent establishment
       maintained by the non-U.S. holder.
 
     - In the case of a non-U.S. holder who is an individual and holds the
       common stock as a capital asset, either:
 
        -- Such holder is not present in the United States for 183 or more days
           during the taxable year of the disposition.
 
        -- Such holder does not have a "tax home" in the United States for U.S.
           federal income tax purposes nor does such holder maintain an office
           or other fixed place of business in the United States to which such
           gain is attributable.
 
     - Such non-U.S. holder is not subject to tax pursuant to the provisions of
       U.S. federal income tax law applicable to certain U.S. expatriates.
 
     - The common stock continues to be "regularly traded on an established
       securities market" for U.S. federal income tax purposes and the non-U.S.
       holder has not held, directly or indirectly, at any time during the
       five-year period ending on the date of disposition (or, if shorter, the
       non-U.S. holder's holding period) more than five percent of the
       outstanding common stock.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Azurix must report annually to the Internal Revenue Service and to each
non-U.S. holder the amount of dividends paid to, and the tax withheld with
respect to, each non-U.S. holder. These reporting requirements apply regardless
of whether withholding was reduced by an applicable tax treaty. Copies of these
information returns may also be made available under the provisions of a treaty
or information exchange agreement with the tax authorities in the country in
which the non-U.S. holder resides or is established. Under current law, U.S.
backup withholding tax, which is a withholding tax currently imposed at the rate
of 31% on certain payments to persons who fail to furnish the information
required under U.S. information reporting requirements, generally will not apply
to dividends paid on common stock to a non-U.S. holder at an address outside the
United States unless the payor has knowledge that the payee is a U.S. person.
However, under the final regulations, dividends paid on common stock after
December 31, 1999 may be subject to backup withholding unless applicable
certification requirements are satisfied.
 
     Payment of the proceeds from a sale of common stock to or through a U.S.
office of a broker will be subject to information reporting and backup
withholding unless the owner certifies as to its status as a non-U.S. holder
under penalties of perjury or otherwise establishes an exemption. Payment of the
proceeds from a sale of common stock to or through a non-U.S. office of a broker
generally will not be subject to information reporting or backup withholding.
However, if such broker is a U.S. person, a "controlled foreign corporation" or
a foreign person that derives 50% or more of its gross income from the conduct
of
                                       104
<PAGE>   110
 
a trade or business in the United States, such payment will be subject to
information reporting, but currently not backup withholding, unless such broker
has documentary evidence in its records that the owner is a non-U.S. holder and
certain other conditions are met or the owner otherwise establishes an
exemption.
 
     Any amounts withheld under the backup withholding rules will be credited
against the non-U.S. holder's federal income tax liability, if any, or refunded,
provided the required information is furnished to the Internal Revenue Service.
 
ESTATE TAX
 
     The fair market value of common stock owned, or treated as owned, by an
individual at the time of his death will be includible in his gross estate for
U.S. federal estate tax purposes and thus may be subject to U.S. estate tax,
even though the individual at the time of death is neither a citizen of nor
domiciled in the United States, unless an applicable estate tax treaty provides
otherwise.

     Azurix, the selling stockholder and Enron have also entered into an
international purchase agreement with the international managers outside the
United States and Canada for whom Merrill Lynch International, Credit Suisse
First Boston (Europe) Limited, Donaldson, Lufkin & Jenrette International,
PaineWebber International (U.K.) Limited, ABN AMRO Rothschild and HSBC
Securities, Inc. are acting as lead managers. Under the international purchase
agreement, and concurrently with the sale of           shares of common stock to
the U.S. underwriters under the U.S. purchase agreement, Azurix and the selling
stockholder have agreed to sell to the international managers, and the
international managers have agreed to purchase from Azurix and the selling
stockholder, an aggregate of           shares of common stock. The initial
public offering price per share and the total underwriting discount per share of
common stock are identical under the U.S. purchase agreement and the
international purchase agreement.
    
 
   
     In the U.S. purchase agreement and the international purchase agreement,
the U.S. underwriters and the international managers, respectively, have agreed,
under the terms of those agreements, to purchase all of the shares of common
stock being sold under those agreements if any of the shares of our common stock
being sold under those agreements are purchased. In the event of a default by an
underwriter, the U.S. purchase agreement and the international purchase
agreement provide that, in some circumstances, the purchase commitments of
nondefaulting underwriters may be increased or the purchase agreements may be
terminated. The closings for the sale of shares of our common stock to the U.S.
underwriters and the international managers are conditioned upon one another.
    
 
                                       106
<PAGE>   112
 
   
     Azurix and Enron have agreed to indemnify the U.S. underwriters and the
international managers against some liabilities, including some liabilities
under the Securities Act, or to contribute to payments the U.S. underwriters and
the international managers may be required to make in respect of those
liabilities.
    
 
   
     The shares of common stock are being offered by the underwriters, subject
to prior sale, when, as and if issued to and accepted by them, subject to
approval of legal matters by counsel for the underwriters and other conditions.
The underwriters reserve the right to withdraw, cancel or modify offers and to
reject orders in whole or in part.
    
 
COMMISSIONS AND DISCOUNTS
 
   
     The U.S. representatives have advised Azurix and the selling stockholder
that the U.S. underwriters propose initially to offer the shares of our common
stock to the public at the initial public offering price set forth on the cover
page of this prospectus, and to certain dealers at such price less a concession
not in excess of $     per share of common stock. The U.S. underwriters may
allow, and such dealers may reallow, a discount not in excess of $     per share
of common stock to certain other dealers. After the initial public offering, the
public offering price, concession and discount may be changed.
    
 
     The following table shows the per share and total public offering price,
the underwriting discount to be paid by Azurix and the selling stockholder to
the U.S. underwriters and the international managers and the proceeds before
expenses to Azurix and the selling stockholder. This information is presented
assuming either no exercise or full exercise by the U.S. underwriters and the
international managers of their over-allotment options.

INTERSYNDICATE AGREEMENT
 
     The U.S. underwriters and the international managers have entered into an
intersyndicate agreement that provides for the coordination of their activities.
Under the terms of the intersyndicate agreement, the U.S. underwriters and the
international managers are permitted to sell shares of common stock to each
other for purposes of resale at the public offering price, less an amount not
greater than the selling concession. Under the terms of the intersyndicate
agreement, the U.S. underwriters and any dealer to whom they sell shares of our
common stock will not offer to sell or sell shares of common stock to persons
who are non-U.S. or non-Canadian persons or to persons they believe intend to
resell to persons who are non-U.S. or non-Canadian persons, and the
international managers and any dealer to whom they sell shares of common stock
will not offer to sell or sell shares of common stock to U.S. persons or to
Canadian persons or to persons they believe intend to resell to U.S. persons or
Canadian persons, except in the case of transactions under the terms of the
intersyndicate agreement.
 
OVER-ALLOTMENT OPTION
 
   
     The selling stockholder has granted an option to the U.S. underwriters,
exercisable for 30 days after the date of this prospectus, to purchase up to an
aggregate of             additional shares of our common stock at the initial
public offering price set forth on the cover page of this prospectus, less the
underwriting discount. The U.S. underwriters may exercise this option solely to
cover over-allotments, if any, made on the sale of our common stock offered
hereby. To the extent that the U.S. underwriters
    
 
                                       107
<PAGE>   113
 
exercise this option, each U.S. underwriter will be obligated, subject to
certain conditions, to purchase a number of additional shares of our common
stock proportionate to such U.S. underwriter's initial amount reflected in the
foregoing table.
 
     The selling stockholder also has granted an option to the international
managers, exercisable for 30 days after the date of this prospectus, to purchase
up to an aggregate of             additional shares of common stock to cover
over-allotments, if any, on terms similar to those granted to the U.S.
underwriters.
 
RESERVED SHARES
 
     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to             of the shares offered hereby to be sold
to some of our directors, officers, employees, customers and other persons with
whom we have an existing relationship who have expressed an interest in
purchasing our common stock, including certain employees, officers and directors
of Enron and its affiliated companies, business associates and related persons.
The number of shares of our common stock available for sale to the general
public will be reduced to the extent that those persons purchase the reserved
shares. Any reserved shares which are not orally confirmed for purchase within
one day of the pricing of the offering will be offered by the underwriters to
the general public on the same terms as the other shares offered by this
prospectus.
 
NO SALES OF SIMILAR SECURITIES
 
   
     Azurix and the selling stockholder have agreed, with certain exceptions,
not to directly or indirectly engage in the following activities for a period of
180 days after the date of this prospectus without the prior written consent of
Merrill Lynch, Pierce, Fenner & Smith Incorporated:
    
 
   
     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of our common stock or securities convertible into or
       exchangeable or exercisable for or repayable with our common stock,
       whether now owned or later acquired by the person executing the agreement
       or with respect to which the person executing the agreement later
       acquires the power of disposition, or file a registration statement under
       the Securities Act relating to any shares of our common stock
    
 
   
     - Enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of our common stock whether
       any such swap or transaction is to be settled by delivery of our common
       stock or other securities, in cash or otherwise, see "Shares Eligible for
       Future Sale"
    
 
   
     As an exception to these restrictions, we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors--Future sales of our common stock may
depress our stock price."
    
 
NEW YORK STOCK EXCHANGE LISTING
 
   
     Azurix is applying to list the common stock on the New York Stock Exchange
under the symbol "AZX." In order to meet the requirements for listing of our
common stock on that exchange, the underwriters have undertaken to sell lots of
100 or more shares to a minimum of 2,000 beneficial owners.
    
 
   
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations among
Azurix, the selling stockholder, Enron, the
    
 
                                       108
<PAGE>   114
 
   
U.S. representatives and the lead managers. The factors considered in
determining the initial public offering price, in addition to prevailing market
conditions, are the valuation multiples of publicly traded companies that the
U.S. representatives and the lead managers believe to be comparable to us,
including adjusted market value to EBITDA multiples, price to book value
multiples and price to earnings multiples, certain of our financial information,
the history of, and the prospects for, our company and the industry in which we
compete, an assessment of our management, our past and present operations, the
prospects for and timing of our future revenues, the present state of our
development, and the above factors in relation to market values and various
valuation measures of other companies engaged in activities similar to ours.
There can be no assurance that an active trading market will develop for our
common stock or that the common stock will trade in the public market subsequent
to this offering at or above the initial public offering price.
    
 
   
     The underwriters do not expect sales of our common stock to any accounts
over which they exercise discretionary authority to exceed 5% of the number of
shares being offered in this offering.
    
 
   
PRICE STABILIZATION AND SHORT POSITIONS
    
 
   
     Until the distribution of our common stock is completed, rules of the SEC
may limit the ability of the underwriters and selling group members to bid for
and purchase our common stock. As an exception to these rules, the U.S.
representatives and the lead managers are permitted to engage in certain
transactions that stabilize the price of our common stock. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of our common stock.
    
 
   
     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the U.S.
representatives and the lead managers may reduce that short position by
purchasing our common stock in the open market. The U.S. representatives and the
lead managers may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.
    
 
   
PENALTY BIDS
    
 
     The U.S. representatives and the lead managers may also impose a penalty
bid on underwriters and selling group members. This means that if the U.S.
representatives or the lead managers purchase shares of our common stock in the
open market to reduce the underwriters' short position or to stabilize the price
of our common stock, they may reclaim the amount of the selling concession from
the underwriters and selling group members who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
     None of Azurix, the selling stockholder, or any of the underwriters makes
any representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of our common stock.
In addition, none of Azurix, the selling stockholder, or any of the underwriters
makes any representation that the U.S. representatives or the lead managers will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
 
OTHER RELATIONSHIPS
 
   
     Some of the underwriters and their affiliates engage in transactions with,
and perform services for, our company, Enron and Enron's affiliates in the
ordinary course of business and have engaged, and may in the future engage, in
commercial banking and investment banking transactions and services with our
company, Enron and Enron's affiliates, for which they have received customary
compensation.

                   UNAUDITED CONDENSED CONSOLIDATED PRO FORMA
                             FINANCIAL INFORMATION
 
   
     The following unaudited condensed consolidated pro forma statement of
income for the year ended December 31, 1998 gives effect to the October 2, 1998
acquisition of Wessex by Azurix ("Wessex Acquisition") and the related
redemption of the preference shares of Wessex and sale of its interest in Wessex
Waste Management Ltd, a joint venture with Waste Management International Plc,
as though each occurred on January 1, 1998. The unaudited condensed consolidated
pro forma statement of income does not include the 1998 results of operations
from Azurix's investment in Obras Sanitarias Mendoza S.A. prior to the date it
was acquired, and does not include any pro forma or historical effect from
Azurix's investment in a water concession for the city of Cancun, Mexico
acquired in 1999 or the proposed acquisition of Philip Utilities Management
Corp.
    
 
     The unaudited condensed consolidated pro forma statement of income has been
prepared based upon the Azurix and Wessex consolidated statements of income
included elsewhere in this prospectus and has been prepared based upon available
information and certain assumptions that the management of Azurix believes are
reasonable. The unaudited condensed consolidated pro forma statement of income
is for informational purposes only, and does not purport to represent what
Azurix's actual results of operations would actually have been had the Wessex
Acquisition, and the related redemption of the preference shares of Wessex and
sale of its interest in Wessex Waste Management Ltd, a joint venture with Waste
Management International Plc, occurred on January 1, 1998. In addition, the
unaudited condensed consolidated pro forma statement of income is not
necessarily indicative of future results of operations of Azurix and should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the Consolidated Financial Statements
of Azurix and Wessex and the related notes thereto included elsewhere in this
prospectus.

              NOTES TO UNAUDITED CONDENSED CONSOLIDATED PRO FORMA
                              STATEMENT OF INCOME
 
   
     The following pro forma adjustments give effect to the Wessex Acquisition,
and the related redemption of the preference shares of Wessex and sale of its
interest in Wessex Waste Management Ltd, a joint venture with Waste Management
International Plc, as though each occurred on January 1, 1998. The historical
results of Wessex for the period prior to the Wessex Acquisition were derived by
combining the Wessex historical audited results for the period April 1, 1998 to
October 2, 1998 and the Wessex historical audited results for the year ended
March 31, 1998, less the historical unaudited results for the nine months ended
December 31, 1997. The unaudited condensed consolidated pro forma statement of
income includes the 1998 results of operations from Azurix's investment in Obras
Sanitarias Mendoza S.A. from the date it was acquired, and does not include any
pro forma or historical effect from Azurix's $13.5 million investment in a water
concession for the city of Cancun, Mexico that closed on March 24, 1999.
    
 
     The cost of the Wessex Acquisition, including transaction costs, was $2.4
billion. The pro forma adjustments are based on a preliminary purchase price
allocation because Azurix is in the process of finalizing its assessment of the
related fair values. This preliminary purchase price allocation includes
tangible assets of $2.7 billion, goodwill of $0.9 billion, liabilities assumed
of $1.1 billion and redeemable preferred stock of $0.1 billion. Azurix does not
believe the final evaluation of these assessments will materially affect the
allocation of the purchase price.
 
     The historical results of operations for Azurix are for the period from
January 29, 1998 (Date of Inception) to December 31, 1998. However,
substantially all of Azurix's results of operations occurred during the fourth
quarter of 1998, subsequent to the Wessex Acquisition.
 
   
     (a) To adjust Wessex historical general and administrative expense for
costs incurred by Wessex prior to the Wessex Acquisition, but directly related
to the Wessex Acquisition.
    
 
   
     (b) To adjust historical Wessex depreciation of tangible assets and
amortization of goodwill acquired in the Wessex Acquisition for the period
during 1998 prior to the Wessex Acquisition. The adjustment to depreciation and
amortization was based on a preliminary purchase price allocation. Goodwill is
being amortized over 40 years.
    
 
   
     (c) To adjust historical equity earnings from Wessex's historical results
to reflect the sale of its interest in Wessex Waste Management Ltd for $337.9
million.
    
 
     (d) To record the following:
 
   
          (1) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated loan notes issued to Wessex
     shareholders to finance the Wessex Acquisition. The average balance
     outstanding was $116.4 million, adjusted for foreign currency exchange
     rates, and an average interest rate of 7.8% was assumed;
    
 
   
          (2) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated affiliate note payable used to finance
     the Wessex Acquisition in the amount of $120.5 million, adjusted for
     average foreign currency exchange rates, at an assumed interest rate of
     6.25%;
    
 
   
          (3) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated funds borrowed under a five year bank
     credit facility used to finance the Wessex Acquisition less a portion of
     the proceeds received from the sale of its interest in Wessex Waste
     Management Ltd that were used to paydown such borrowings. The average
     balance outstanding was $209.7 million, adjusted for foreign currency
     exchange rates, and an average interest rate of 8.2% was assumed;
    
 
                                       F-4
<PAGE>   121
 
   
          (4) Interest expense for the period January 1, 1998 to December 9,
     1998 on U.K. pounds sterling denominated funds borrowed to redeem Wessex's
     preference shares. The weighted average funds borrowed was $215.5 million,
     adjusted for foreign currency exchange rates, and an average interest rate
     of 8.1% was assumed.
    
 
     (e) To reflect the reduction in dividends related to the redemption of the
Wessex preference shares.
 
     (f) To record the tax impact of the pro forma adjustments described above
at the U.K. statutory rate of 31%, excluding non-deductible goodwill
amortization.

responsibility of Azurix Corp.'s management. Our responsibility is to express an
opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Azurix Corp. and
subsidiaries as of December 31, 1998, and the results of their operations, cash
flows and changes in stockholder's equity for the period from January 29, 1998
(Date of Inception) to December 31, 1998, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS
 
     Azurix Corp. was formed by Enron Corp. ("Enron") on January 29, 1998 ("Date
of Inception"). Azurix Corp. and its consolidated subsidiaries (collectively
"Azurix") are engaged in the business of acquiring, owning, operating and
managing water and wastewater assets, providing water and wastewater related
services and managing and developing resources in the global water industry.
Azurix is a wholly owned subsidiary of Atlantic Water Trust ("Atlantic Water")
in which Enron and Marlin Water Trust each hold a 50% voting interest. During
1998, Azurix indirectly acquired all of the outstanding ordinary share capital
of Wessex Water Plc ("Wessex") (see Note 2) and Enron contributed to Azurix the
outstanding common stock of a subsidiary that in June 1998 acquired a 32.1%
ownership interest in Obras Sanitarias Mendoza S.A. ("OSM"). Wessex and OSM
provide water and wastewater treatment services in southwestern England and the
Province of Mendoza, Argentina, respectively.
 
     Azurix entered into an agreement on December 19, 1998 to purchase 49.9% of
an entity whose principal asset is the water concession for the city of Cancun,
Mexico ("Cancun"). This agreement was not binding until certain material
conditions were met, and these conditions were met subsequent to December 31,
1998. The purchase price is $13.5 million and Azurix has agreed to provide up to
$25.0 million in debt financing. The acquisition is subject to certain
governmental approvals and is scheduled to close in March 1999.
 
     Azurix Corp. was incorporated on January 29, 1998, and as a result, the
Consolidated Statement of Income, Consolidated Statement of Comprehensive Income
(Loss), Consolidated Statement of Cash Flows and Consolidated Statement of
Changes in Stockholder's Equity are from the Date of Inception to December 31,
1998. However, substantially all of Azurix's results of operations, cash flows
and equity transactions occurred during the fourth quarter of 1998, subsequent
to the Wessex acquisition.
 
CONSOLIDATION POLICY AND USE OF ESTIMATES
 
     The consolidated financial statements include the accounts of all
majority-owned subsidiaries and are prepared in accordance with generally
accepted accounting principles in the United States ("U.S."). All significant
intercompany balances and transactions have been eliminated in consolidation.
Azurix uses the equity method of accounting for all investments where it owns
less than a majority of the voting stock but is able to exercise significant
influence over the operating and financial policies of the investee.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
REVENUE RECOGNITION
 
   
     Operating revenue represents income earned in the ordinary course of
business, excluding value added tax. Revenue for metered customers is recognized
based on actual usage and accrued based on the estimated amount of water sold
but not billed as of the balance sheet date. Revenue for non-metered customers,
who pay an annual fixed charge based on the rateable value of their property, is
recognized uniformly over the year.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
     Azurix utilizes derivative financial instrument contracts for non-trading
purposes to manage exposure to fluctuations in interest rates and foreign
currency exchange rates. Hedge accounting is utilized in non-trading activities
where there is a high correlation of price movements in the derivative and the
contract is designated as a hedge. In instances where the anticipated
correlation of price movements no longer exists, hedge accounting is terminated
and future changes in the value of the derivative financial instruments are
recognized as gains or losses to net income.
 
     Interest rate swaps involve the exchange of amounts based on a fixed
interest rate for amounts based on variable interest rates over the life of the
contract without an exchange of the notional amount upon which payments are
based. The difference to be received or paid is recognized in income over the
life of the contracts as adjustments to interest expense.
 
     Currency swap contracts are denominated in one foreign currency and are to
be repaid in another currency. These contracts are designated as hedges of firm
commitments to pay interest and principal on debt, which would otherwise expose
Azurix to foreign currency risk.
 
     The fair values of the swap contracts are not recognized in the financial
statements. The income and cash flow impact of financial instruments is
reflected as an adjustment of the hedged item. Gains and losses on terminations
of interest rate and currency swap contracts are deferred as an adjustment to
the carrying amount of the outstanding obligation and amortized as an adjustment
to interest expense related to the obligation over the remaining term of the
original contract life of the terminated swap contract. In the event of early
extinguishment of the obligation, any realized or unrealized gain or loss from
the swap would be recognized in net income at the time of extinguishment.
 
INCOME TAXES
 
     Azurix accounts for income taxes under the provisions of Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
Under the asset and liability method of SFAS No. 109, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. For U.S. tax purposes, Azurix is
presently a member of Enron's consolidated group and is included in Enron's
consolidated federal income tax return. Members of the consolidated group are
charged with the amount of income tax expense (benefit) determined as if they
filed separate federal income tax returns. There is no formal tax sharing
arrangement between Enron and Azurix.
 
EARNINGS PER COMMON SHARE
 
     SFAS No. 128, "Earnings Per Share," requires dual presentation of earnings
per common share and earnings per common share assuming dilution on the face of
the income statement. Basic earnings per share is computed by dividing the net
income available to common stockholders by the weighted average number of common
shares outstanding during the period. Diluted earnings per common share is
computed by adjusting basic earnings per share for the net income and share
effect of the potential conversion to common shares of all dilutive securities.
For the year ending December 31, 1998, Azurix did not have any securities
outstanding that could have been potentially converted into common shares,
therefore, basic and diluted earnings per share are the same.
 
CASH EQUIVALENTS
 
     Azurix considers all highly liquid investments with original maturities of
three months or less to be cash equivalents.

PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is stated at cost. Cost of acquired property,
plant and equipment includes an allocation of the purchase price based on the
asset's fair market value. Cost of property, plant and equipment placed in
service includes direct charges for material, labor and services and indirect
charges related to construction, such as engineering, supervision, payroll taxes
and employee benefits. The October 1998 acquisition of Wessex represents
substantially all of the property, plant and equipment as of December 31, 1998
(see Note 2). Additions, replacements, modifications and enhancements to units
of property are capitalized. Major improvements to leasehold properties are
amortized over the shorter of the asset life or the life of the respective
lease. Repairs, maintenance and minor replacements are charged to operations and
maintenance expense as incurred. Interest capitalized is based on the average
value of construction work in progress at Azurix's average borrowing rate during
the period. The amount of interest capitalized during 1998 was approximately
$2.3 million.
 
     Azurix's infrastructure assets comprise a network of systems of mains and
sewers, impounding and pumped raw water storage reservoirs, dams, sludge
pipelines and infrastructure investigations and studies.
 
     The cost of property, plant and equipment is charged to depreciation using
the straight-line method over the estimated useful lives of the assets.
Depreciation is computed based on estimated useful lives as follows:

LONG-LIVED ASSETS
 
     In accordance with SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of," long-lived
assets held and used by Azurix are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. For purposes of evaluating the recoverability, a test is
performed comparing the estimated future undiscounted cash flows associated with
the asset to the asset's carrying amount, including allocated goodwill, to
determine if a write-down to market value or discounted cash flow value is
required.
 
GOODWILL
 
     Goodwill represents the excess of purchase price and related costs over the
value assigned to the net assets of businesses acquired (see Note 2). Goodwill
is amortized on a straight-line basis over the estimated useful life, not to
exceed 40 years. Accumulated amortization of goodwill at December 31, 1998 was
$5.5 million.
 
OTHER ASSETS
 
     Other assets consist primarily of deferred charges, such as financing costs
and external costs of acquisition activities. Deferred financing charges are
amortized to interest expense over the lives of the related debt issuances and
external acquisition costs are capitalized as a cost of successful acquisitions
or expensed during the period in which it is determined that the project is
unsuccessful or the pursuit is terminated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
DEFERRED INCOME
 
     Azurix bills certain customers in advance of providing water and wastewater
services and classifies these amounts as "Deferred income" on the Consolidated
Balance Sheet until earned.
 
PENSION BENEFITS
 
     The pension plans maintained by Wessex (see Note 12) are of the defined
benefit type, and are valued by an independent actuary. Current service costs
for the plans are accrued in the period to which they relate. Prior service
costs and actuarial gains and losses, if any, relating to amendments to the
plans, are recognized on a basis designed to spread the costs over the remaining
average service lives of employees.
 
FOREIGN CURRENCY TRANSLATION
 
     The functional currency for Azurix's foreign operations is the applicable
local currency. The translation from the applicable foreign currencies to U.S.
dollars is performed for balance sheet accounts using the current exchange rates
in effect at the balance sheet date and for revenue and expense accounts, using
the weighted average exchange rate during the period or, where known or
determinable, at the rate on the date of the transaction for significant items.
The resulting translation adjustments are recorded in comprehensive income as a
component of stockholder's equity and are included in income only upon the sale
or liquidation of the underlying investments.
 
ENVIRONMENTAL COSTS
 
     Environmental expenditures that relate to current operations are expensed
as incurred. Expenditures providing a future benefit are capitalized as
appropriate. Remediation costs that relate to an existing condition caused by
past operations are accrued when it is probable that these costs will be
incurred and can be reasonably estimated.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." This
statement establishes accounting and reporting standards for derivative
instruments, including certain instruments embedded in other contracts
(collectively referred to as derivatives), and for hedging activities. It
requires an entity to recognize all derivatives as either assets or liabilities
in the statement of financial position and measure those instruments at fair
value. This statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. Azurix is currently evaluating and has not yet
determined the effect that the adoption of SFAS No. 133 will have on its
financial statements.
 
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") 98-5, "Reporting on the Costs of Start-Up
Activities," which requires that costs for start-up activities and organization
costs be expensed as incurred and not capitalized as had previously been
allowed. SOP 98-5 is applicable to all financial statements for fiscal years
beginning after December 15, 1998 and initial adoption is required to be
reflected as a cumulative effect of accounting change. Azurix adopted the
treatment prescribed by SOP 98-5 in 1998, the year of Azurix's inception, and
therefore there is no cumulative effect.
 
SEGMENT, GEOGRAPHIC AND QUARTERLY REPORTING
 
     The FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise
and Related Information," which is effective for fiscal years beginning after
December 31, 1997, and establishes
                                      F-15

standards for reporting information about operating segments in annual financial
statements and requires selected information about operating segments in interim
financial reports. Operating segments are defined as components of an enterprise
about which separate financial information is available and evaluated regularly
by the chief operating decision maker, or decision making group, in deciding how
to allocate resources and in assessing performance. The operating subsidiaries
of Azurix in 1998 operated in one segment and were substantially located in one
geographic region. In addition, Azurix's operations began in the fourth quarter
of 1998 and therefore separate quarterly disclosures have been omitted.
    
 
NOTE 2 -- BUSINESS ACQUISITION
 
     On October 2, 1998 ("Wessex Acquisition Date"), Azurix, through its
indirect wholly owned subsidiary Azurix Europe Ltd ("Azurix Europe"), acquired
over 90% of the outstanding ordinary share capital of Wessex. On that same date,
Azurix Europe issued notices to the remaining Wessex ordinary shareholders,
informing them that it intended to exercise its rights under the English
Companies Act to acquire compulsorily all of the outstanding ordinary shares.
The compulsory share acquisition was completed in November 1998. The cost of the
Wessex acquisition, including transaction costs was $2.4 billion. The cost
included a combination of cash consideration paid to Wessex shareholders, net of
$1.7 million cash acquired, and the issuance of loan notes to Wessex
shareholders in the face amount of $119.8 million (see Note 7). On October 2,
1998, Wessex had cumulative mandatorily redeemable preference shares
outstanding. These were redeemed by Wessex in December 1998.
 
     The purchase method of accounting was utilized, and accordingly, the assets
and liabilities of Wessex have been recorded at their estimated fair values on
the date of acquisition. The excess of the purchase price over the fair values
of the net assets acquired has been recorded as goodwill, and is being amortized
on the straight-line basis over 40 years. The results of operations of Wessex
have been included in the consolidated financial statements since the date of
acquisition. Assets acquired, liabilities assumed, debt issued and consideration
paid (which includes proceeds from borrowings by Azurix Europe), as a result of
the Wessex acquisition are detailed below. The allocation of the purchase price
to the net assets acquired is preliminary because Azurix is in the process of
finalizing its assessment of the related fair values. Azurix does not believe
the final evaluation of these assessments will materially affect the allocation
of the purchase price. The preliminary allocation of the purchase price is as
follows:

additional amortization expense as a result of goodwill, increased depreciation
expense resulting from allocation of fair market value to fixed assets acquired,
increased interest expense on acquisition debt and preference share redemption
and the sale of Wessex's interest in UK Waste (see Note 3). The unaudited pro
forma financial information is not necessarily indicative of the results of
operations that would have occurred had the Wessex acquisition occurred on the
date indicated, and should not be viewed as indicative of operations in future
periods.
 
NOTE 3 -- SALE OF ACQUIRED EQUITY INVESTMENT
 
     On November 30, 1998, Azurix, sold its interest in Wessex Waste Management
Ltd, a joint venture with Waste Management International Plc ("WMI") that does
business as UK Waste, to WMI for $337.9 million. Azurix's interest in UK Waste
was acquired in the Wessex acquisition (see Note 2). UK Waste provides solid
waste collection, treatment and recycling services throughout the United Kingdom
("U.K.").
 
     The value allocated to the equity investment in purchase accounting was
based on the cash flows during the period UK Waste was owned by Azurix,
including incremental debt costs incurred during the holding period. Azurix's
results of operations do not reflect the equity earnings of UK Waste during the
ownership period of $2.5 million and no adjustments to the carrying amount of
the investment were necessary. Accordingly, Azurix recorded no gain or loss from
the sale.

NOTE 6 -- SHORT-TERM DEBT
 
     As of December 31, 1998, Azurix had $424.0 million outstanding from credit
facilities with major commercial banks. Of this amount, $399.1 million relates
to committed credit facilities and the remaining $24.9 million relates to credit
facilities that are on an uncommitted basis. Interest accrues on the committed
credit facilities and the uncommitted facilities based on LIBOR plus 0.18% and
LIBOR plus a negotiated margin, respectively. The weighted average interest rate

outstanding as of December 31, 1998 was 6.66%. Azurix pays commitment fees of
0.09% on the unused portion of committed lines of credit. The facilities expire
in April 1999. Azurix intends to refinance the $424.0 million of short-term bank
borrowings with long-term debt. If the refinancing is not completed, Azurix will
use amounts available under the Senior Credit Facility (see Note 7) to refinance
the short-term bank borrowings on a long-term basis and accordingly, has
reclassified its short-term bank borrowings as long-term debt.

     Azurix entered into a United Kingdom pounds sterling ("U.K. Pounds
Sterling") denominated senior secured bank credit facility in August 1998, as
amended ("Senior Credit Facility"). At December 31, 1998, it consisted of a term
loan facility of $322.6 million and a revolving credit facility of $575.3
million bearing interest at a rate of LIBOR plus 0.625%, which was 6.9% at
December 31, 1998. The amounts outstanding at December 31, 1998 were $211.2
million and $8.3 million, under the term loan facility and the revolving credit
facility, respectively. The remaining term loan capacity of $111.4 million is
used to secure a substantial portion of the Loan Notes, described below. The
term loan facility requires repayment of $199.5 million by July 24, 2000, and
repayment of any remaining outstanding term loans in July 2003. The revolving
credit facility terminates in July 2003. Azurix may borrow up to $99.8 million
of the revolving credit facility balance available for general corporate
purposes. Azurix has pledged all of a subsidiary's existing assets, including
all of the ordinary shares of Wessex, under this facility. The unused borrowing
capacity under the revolving credit facility at December 31, 1998 was $567.0
million. Azurix incurs commitment fees of 0.3125% on the unused portion of this
facility, which are recorded as interest expense.
 
     Azurix issued U.K. Pounds Sterling denominated loan notes of $117.2 million
face value, as of December 31, 1998, to Wessex shareholders in lieu of cash
consideration for the ordinary shares purchased in the Wessex acquisition ("Loan
Notes") (see Note 2). The notes are redeemable, at the option of the holder,
semi-annually beginning September 30, 1999, with final redemption occurring
September 30, 2005. The Loan Notes may be redeemed at the holders' option within
one year, and therefore, are potential current obligations. If redeemed by the
holders' prior to maturity, Azurix will utilize available capacity on the Senior
Credit Facility to refinance the Loan Notes on a long-term basis, and
accordingly, the Loan Notes are classified as long-term debt. Interest on the
Loan Notes accrues at LIBOR and is payable semi-annually. The LIBOR rate for the
period the Loan Notes were outstanding during 1998 was 7.125%.
 
     The European Investment Bank ("EIB") credit facilities consist of two
separate loans, one of which has a floating interest rate based on LIBOR less
0.25%, and the other has a fixed interest rate of 11.6%. The floating rate
obligation, due October 2001, has an outstanding balance of $49.9 million at

December 31, 1998 and is U.S. dollar denominated. The fixed rate loan,
denominated in Italian lire, has an outstanding balance of $18.8 million at
December 31, 1998 and is payable in semiannual installments through June 2002.
    
 
   
     The U.K. Pounds Sterling denominated capital lease obligation provides for
semi-annual payments. At December 31, 1998, future minimum lease payments total
$129.1 million, including $19.4 million representing interest. Currently, $158.3
million of historical cost and $21.5 million of related accumulated amortization
is recorded under a capital lease and included in property, plant and equipment.
    
 
     Each of these financing agreements contains certain restrictive covenants,
including among other things, limitations on borrowings, the maintenance of
certain financial ratios such as interest coverage, net worth and debt to equity
and contracts to perform or refrain from undertaking certain acts. The financing
contracts include standard events of default, including non-payment,
cross-defaults and insolvency. Azurix is currently in compliance with these
covenants.
 
     Long-term borrowing and capital lease obligation maturities over the next
five years are $27.0 million in 1999, $230.0 million in 2000, $84.6 million in
2001, $36.3 million in 2002 and $561.2 million in 2003.
 
     Azurix has executed interest rate and currency swap contracts related to
its outstanding debt (see Note 8).
 
     Azurix has an affiliate note payable of $121.4 million outstanding at
December 31, 1998 (see Note 11).
 
NOTE 8 -- FINANCIAL INSTRUMENTS
 
     Azurix uses derivative financial instruments in the normal course of its
business for purposes other than trading. These financial instruments include
interest rate and currency swap contracts. Azurix has U.K. Pounds Sterling ("L")
interest rate swap contracts having a total notional principal amount of $833.6
million. Interest rate swap contracts relating to notional principal amounts of
$665.1 million, $149.7 million and $18.8 million terminate in 2000, 2001 and
2002, respectively. Azurix also has cross-currency swap contracts to exchange
U.S. dollars of $49.9 million to U.K. Pounds Sterling of L30 million, which
expires in 2001, and Italian lire of 25.0 billion to U.K. Pounds Sterling of
L11.3 million, which expires in 2002.
 
     The carrying amount of cash and cash equivalents, trade accounts receivable
(net of an allowance for doubtful accounts) and accounts payable and accruals
approximates their fair value due to their short-term nature. The fair value of
long-term debt and affiliate long-term debt is based on the quoted market prices
for the same or similar issues or on the current rates offered to Azurix for
debt of the same remaining maturities. The fair value of currency swap and
interest rate swap contracts was determined based on a model which estimates the
fair value of these swap contracts using market rates at December 31, 1998 or
was based on quoted market prices for similar instruments with similar

     Azurix is exposed to certain risks due to the nature of derivative
financial instruments. In the event of non-performance by third parties, the
amounts of interest rate and currency swap contracts are potentially subject to
credit risk. Third parties to these contracts are major commercial banks with
high-quality credit ratings. Accordingly, Azurix does not anticipate
non-performance by any of these counterparties on these financial instruments.
Azurix is exposed to market risk in the form of foreign exchange rate and
interest rate risks. Several variable and fixed rate loans in foreign currencies
are hedged through a combination of cross-currency swaps and interest rate
swaps.

     Azurix has U.K. ACT credit carryforwards at December 31, 1998 of
approximately $83.1 million that can be used to offset U.K. taxes payable in
future years. At December 31, 1998, the U.K. ACT credit has an indefinite
carryforward period. At December 31, 1998, Azurix has a U.S. tax loss
carryforward of approximately $14.7 million that will expire in 2018. Management
believes that sufficient uncertainty exists regarding the realizability of the
U.S. loss carryforwards, such that a valuation is appropriate. Such deferred tax
benefits will be reassessed as future business activity occurs. At December 31,
1998, Azurix has U.K. subsidiary company loss carryforwards of approximately
$11.8 million that can be carried forward for an indefinite period. However, due
to restrictions on the use of such loss carryforwards, the benefits have not
been reflected in Azurix's results of operations.
    
 
     U.S. and foreign income taxes have been provided for earnings of foreign
subsidiary and affiliate companies that are expected to be remitted to the U.S.
Foreign subsidiaries' and affiliates' cumulative undistributed earnings of
approximately $43.2 million are considered to be indefinitely reinvested outside
the U.S. and, accordingly, no U.S. income taxes have been provided thereon. In
the event of a distribution of those earnings in the form of dividends, Azurix
may be subject to both foreign withholding taxes and U.S. income taxes net of
allowable foreign tax credits.

(1) One-time tax levied on private utilities by the U.K. government. This amount
    was recorded to Wessex's net income in 1997.
 
NON-CASH TRANSACTIONS
 
     During 1998, Azurix issued debt in the form of the Loan Notes in connection
with the Wessex acquisition (see Note 7). During 1998, Azurix received a capital
contribution from Enron of the outstanding stock of a subsidiary that holds an
interest in OSM. The transfer was recorded at the book value of Enron of $71.8
million.
 
NOTE 11 -- RELATED PARTY TRANSACTIONS
 
     During 1998, Azurix entered into a U.K. Pounds Sterling denominated loan
with Enron for $119.7 million. Interest of $2.1 million accrued during the
period the loan was outstanding at LIBOR plus 0.8%. The principal and accrued
interest were repaid to Enron in 1998.
 
     Enron will exert influence over the policies, management and affairs of
Azurix. Certain individuals who serve as officers and directors of Enron also
serve as directors of Azurix. The directors and officers of Enron have fiduciary
duties to manage Enron, including its investments in subsidiaries and affiliates
in a manner beneficial to Enron and its stockholders. Similarly, the directors
and officers of Azurix have fiduciary duties to manage Azurix in a manner
beneficial to Azurix and its stockholders.
 
     Enron and Azurix propose to enter into an agreement that addresses the
scope of Azurix's business and it is anticipated that it will provide that
certain activities in which Enron and its affiliates may engage are permitted,
even if those activities have a competitive impact on Azurix. In general, it is
anticipated that Enron will be permitted to engage in any business whatsoever,
including water, wastewater and other businesses competing with Azurix, and may
compete in public tenders against Azurix, provided the business is conducted and
opportunities are identified and developed through Enron's own personnel and not
through Azurix. The agreement is expected to contain other provisions regarding
the activities to be performed by Azurix and Enron's involvement in those
activities.
 
     Enron provides office space (see Note 15) to Azurix and various services
such as computer hardware and software and support services such as risk
management, accounts payable, payroll and information technology services. Costs
are allocated to Azurix based upon usage, or where no direct method can be
efficiently applied due to administrative burden, upon factors such as
annualized payroll or employee headcount.
 
     Employees, other than Wessex employees, are covered by various employee
benefit plans of Enron such as retirement, stock option, medical, dental, life
insurance and other benefit plans. These costs are allocated to Azurix based
upon Enron's costs of administering and providing the benefit plans. During 1998
the expense recorded under the plan arrangements was approximately $1.4 million.
 
   
     During 1998, Enron advanced to Azurix $17.7 million related to office space
and other services provided by Enron and costs of various benefit plans for
certain employees, each described above. This amount is reported in the
Consolidated Balance Sheet as a component of "Accounts payable -- affiliates."

     Management believes the above allocation methods and costs are reasonable.
 
     A director of a subsidiary of Wessex owns certain assets utilized in the
subsidiary's operations. The subsidiary was charged $0.1 million for the use of
those assets during the period Azurix owned Wessex.
 
BRISTOL WATER TRUST
 
     During 1998, Azurix entered into a U.K. Pounds Sterling denominated senior
loan agreement with Bristol Water Trust, as amended and restated, an affiliate
company wholly owned by Atlantic Water. The note accrues interest at 6.25% per
annum and is payable semi-annually, beginning June 1999. Under the note
agreement maturing December 2001, prepayment is allowed in whole or part at any
time. The principal balance outstanding at December 31, 1998 was $121.4 million.
Interest expense recorded for 1998 was $1.9 million.
 
NOTE 12 -- PENSION BENEFITS
 
     Wessex maintains three defined benefit pension plans that cover
substantially all of its employees. The assets are held in separate trustee
administered funds. The pension cost charged to the consolidated statement of
income has been determined on the advice of independent qualified actuaries and
is accrued over the service lives of the employees expected to be eligible to
receive such benefits.
 
     The following weighted average assumptions were used in determining the
funded status and pension charge for the period October 2, 1998 through December
31, 1998:

NOTE 13 -- STOCKHOLDER'S EQUITY
 
COMMON STOCK
 
     During 1998, Azurix issued 1,000 shares of $1.00 par value common stock. On
February 2, 1999, Azurix effected a 100,000-for-one stock split and restated the
par value to $0.01 that resulted in 100 million shares issued and outstanding.
Share and per share data for 1998 presented herein has been adjusted to give
effect to this split as if it had occurred on the Date of Inception.
 
ADDITIONAL PAID-IN CAPITAL
 
     During 1998, Azurix received cash contributions of approximately $1.6
billion. In addition, Azurix received a capital contribution from Enron of the
outstanding stock of a subsidiary that holds a 32.1% ownership interest in OSM.
The transfer was recorded at Enron's book value of $71.8 million.
 
STOCK INCENTIVE PLAN
 
     In February 1999, Azurix established a stock incentive plan (the "Plan")
which provides for the granting or awarding of stock options and restricted
stock to directors, officers and key employees of Azurix. At any particular
time, the number of shares of common stock issued under the Plan may not exceed
15% of the total number of shares of common stock outstanding. Under the Plan,
Azurix granted

options to purchase 7.8 million shares of its common stock, at an exercise price
per share of $16.72. The options vest from three to five years after the grant
date and expire ten years after the grant date.
 
NOTE 14 -- RESTRICTED NET ASSETS OF SUBSIDIARIES
 
     Certain subsidiaries of Azurix Corp. have governmental and regulatory
restrictions or approvals required in order to pay dividends or make
intercompany loans and advances to it. The amount of restricted net assets of
Azurix Corp. subsidiaries at December 31, 1998 is approximately $1.5 billion.
 
NOTE 15 -- COMMITMENTS AND CONTINGENCIES
 
     Azurix leases office space from Enron under a lease obligating only Enron
and specific subsidiaries and affiliates (see Note 11). Azurix has no
contractual obligation under these office lease agreements but pays to Enron the
amount determined in the lease or the contract rate applied to square footage
occupied. Azurix accrued rent expense to Enron for office space totaling $0.3
million in 1998.
 
     Azurix leases property under various operating leases. Future minimum
operating lease payments as of December 31, 1998, in the aggregate and for each
of the five succeeding fiscal years, are as follows:

</TABLE>
 
     Azurix has contractual commitments for capital expenditures to be incurred
after December 31, 1998 of $130.2 million.
 
     Azurix is involved in various claims and lawsuits incidental to its
business. Although no assurances can be given, Azurix believes that the ultimate
resolution of such items will not have a material effect on its results of
operations or financial position.
 
     Azurix is subject to extensive federal, foreign, state and local
environmental laws and regulations. We anticipate future changes in, or
decisions affecting, regulatory regimes that will serve to expand or tighten
regulatory controls. Some of these changes or decisions could have a material
adverse effect on our financial position and results of operations.
 
     A substantial portion of Azurix's revenues are subject to governmental
regulation of the rates that it may charge to its customers. The U.K. government
is currently conducting a periodic review of the price limits for water and
sewerage companies in England and Wales that is expected to result in new price
limits for the period from April 1, 2000 through 2005 that will be lower than
current price limits. Although we are unable to predict the precise outcome of
the current U.K. rate review, it is likely to significantly reduce Wessex's
revenues and earnings, but should not have a material adverse effect on Azurix's
financial position.

NOTE 16 -- EVENTS SUBSEQUENT TO THE DATE OF REPORT OF INDEPENDENT PUBLIC
ACCOUNTANTS (UNAUDITED)
    
 
   
     On February 25, 1999, in connection with the Cancun acquisition, Azurix
funded $15.0 million of the $25.0 million in debt financing it had agreed to
provide (see Note 1). The Cancun acquisition closed on March 24, 1999.
    
 
     In March 1999, Azurix filed a registration statement with the Securities
and Exchange Commission for an underwritten initial public offering of shares of
common stock.
 
   
     Azurix entered into an agreement on March 25, 1999 to acquire 100% of the
stock of Canadian-based Philip Utilities Management Corporation ("PUMC") for
$107 million. PUMC is a water and wastewater services company in the U.S. and
Canada that provides operations and management, engineering, residuals
management and underground infrastructure development services for municipal
water and wastewater facilities. The acquisition is subject to regulatory and
municipal approvals and other third party consents and is expected to close in
the second quarter of 1999.
    
 
   
     On March 30, 1999, Azurix completed a U.K. Pounds Sterling denominated bond
offering in the amount of $483.5 million. Net proceeds of $477.7 million were
primarily used to refinance the $448.4 million of short-term bank borrowings
(see Note 6) that were outstanding on that date. The bonds mature March 30,
2009. Interest of 5.875% is payable annually.

To the stockholder of Wessex Water Ltd (formerly Wessex Water Plc):
 
     We have audited the accompanying consolidated statements of income, changes
in stockholders' equity and cash flows of Wessex Water Plc (now renamed Wessex

from April 1, 1998 to October 2, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the results of operations, cash flows and changes in
stockholders' equity of Wessex Water Plc (now renamed Wessex Water Ltd)
(predecessor company) and subsidiaries for the period from April 1, 1998 to
October 2, 1998 in conformity with generally accepted accounting principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The accompanying consolidated financial statements include the operations
of Wessex Water Plc (now renamed Wessex Water Ltd) and its subsidiaries
("Wessex"). On October 2, 1998, Wessex was purchased by Azurix Europe Ltd, a
wholly owned subsidiary of Azurix Corp. ("Azurix"). The financial statements of
Wessex have been prepared for the purpose of presenting the financial statements
of the predecessor company of Azurix.
 
     These financial statements have been prepared in accordance with generally
accepted accounting principles in the United States ("US GAAP"). The functional
currency of Wessex is pounds sterling ("GBP"). These accounts have been
presented using US dollars ("USD") as the reporting currency by translating the
functional currency financial statements using the current rate methodology
described in the Statement of Financial Accounting Standard ("SFAS") 52,
"Foreign Currency Translation."
 
     The period from April 1 to October 2, 1998 will hereafter be referred to as
the "six months ended October 2, 1998."
 
NATURE OF OPERATIONS
 
     Wessex Water Plc was incorporated on April 1, 1989. On September 1, 1989,
Wessex Water Plc acquired the entire issued share capital of Wessex Water
Services Ltd, a company formed to continue the business of Wessex Water
Authority, as a result of the privatization by the UK government of the water
industry in England and Wales. The acquisition was effected through the issue of
49,998 Wessex shares to the Secretary of State for the Environment which were
credited as fully paid. The assets and liabilities acquired by Wessex were
recorded at book value as Wessex was owned by the UK government at the date of
the transfer making the transaction an exchange between entities under common
control. Wessex's principal activity is the provision of water supply and
wastewater services in southwestern England through its wholly owned subsidiary,
Wessex Water Services Ltd. Wessex's other business activities include SC
Technology AG ("SC Technology"), which does business as Swiss Combi and sells
and operates sludge drying plants.
 
     Wessex Water Services Ltd is licensed to operate as a water and sewerage
company in its region, subject to regulation of its water supply and wastewater
treatment services by government agencies including the Office of Water Services
and the Drinking Water Inspectorate. Wessex is subject to regulation of the
rates it may charge for its regulated water supply and wastewater treatment
businesses.
 
BASIS OF CONSOLIDATION
 
     The consolidated financial statements include the financial statements of
Wessex Water Plc and all its majority owned and controlled subsidiaries. All
inter-company transactions are eliminated as part of the consolidation process.
 
     Investments in companies in which Wessex owns 20 percent to 50 percent of
the voting stock and has significant influence are accounted for using the
equity method with Wessex's share of profits and losses included in the
consolidated income statement. Wessex's share of post-acquisition retained
profits/losses is added to/deducted from the cost of the investee in the
consolidated balance sheet.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
USE OF ESTIMATES
 
     Preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
FOREIGN CURRENCIES
 
     On consolidation, assets and liabilities of subsidiaries denominated in
foreign currencies, where the local currency is the functional currency, have
been translated at year-end rates. Income and expense items are translated using
the annual weighted average rates of exchange or, where known or determinable,
at the rate on the date of the transaction for significant items. Adjustments
arising from the translation have been recorded in other comprehensive income
and are included in income only upon sale or liquidation of the underlying
investments.
 
     Transactions in currencies other than the functional currency are recorded
at the rate of exchange at the date of the transaction. Assets and liabilities
in currencies other than the functional currency are translated at year-end
rates. Any resulting exchange differences are taken to the consolidated income
statement.
 
     The exchange rates used to translate the GBP functional currency financial
statements to USD were:

CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents represent cash and short-term highly liquid
investments with original maturities of three months or less.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment assets are stated at historical cost, less
accumulated depreciation. Depreciation is charged on a straight-line basis over
the estimated useful lives of the respective assets, based on the following
useful lives:

     Major improvements to leasehold properties are amortized over the shorter
of the asset life and the life of the respective lease.

                         (NOW RENAMED WESSEX WATER LTD)
                             (PREDECESSOR COMPANY)
 
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Interest is capitalized on qualifying assets during the time required to
prepare the assets for their intended use using Wessex's weighted average
borrowing rate. The capitalized interest is amortized over the life of the
assets.
 
GOODWILL
 
     Goodwill is the excess of the purchase price over the fair value of the
identifiable assets acquired less the liabilities assumed of the acquired
company. Goodwill is capitalized and amortized over its estimated useful life
which ranges from twenty years (SC Technology) to forty years (Wessex Waste
Management Ltd.).
 
LEASES
 
     Assets held under finance lease agreements are treated as tangible assets
and the present value of the related lease payments is recorded as a liability.
Costs for operating leases are charged to the income statement in the period
incurred.
 
LONG-LIVED ASSETS
 
     Wessex evaluates the carrying value of long-lived assets to be held and
used, including goodwill and other intangible assets, when events and
circumstances warrant such a review. The carrying value of a long-lived asset is
considered impaired when the estimated undiscounted cash flow from such an asset
is less than its carrying value. In that event, a loss is recognized based on
the amount by which the carrying value exceeds the estimated fair market value
of the long-lived asset. Fair market value is determined primarily using the
estimated cash flows discounted at a rate commensurate with the risk involved.
 
TAXATION
 
     Provision is made for all taxes payable in respect of profit earned in the
year. Deferred income tax is provided using the liability method for all
temporary differences arising between the tax basis of assets and liabilities
and their carrying value for financial reporting purposes, using the enacted tax
rate. Deferred tax assets are reduced by a valuation allowance to the extent
that it is more likely than not that all or part of the asset will not be
realized. No deferred tax liability has been recognized for undistributed
earnings of domestic subsidiaries since such earnings can be transferred to the
parent company without tax consequences.
 
REVENUE RECOGNITION
 
     For metered customers, Wessex recognizes revenue based on actual usage and
accrues revenue for the estimated amount of water sold but not billed as of the
balance sheet date. The revenue for non-metered customers, who pay an annual
fixed charge based on the rateable value of their property, is recognized
uniformly over the year.
 
PENSIONS
 
     Current service costs for defined benefit plans are accrued in the period
to which they relate. Prior service costs, if any, relating to amendments of the
plans, are recognized over the remaining average service lives of those
employees. The pension schemes are of the defined benefit type, which are
externally funded and valued by an independent actuary.

                             (PREDECESSOR COMPANY)
 
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
INVESTMENTS IN EQUITY SECURITIES
 
     Available-for-sale securities are reported at fair value and individual
securities are classified as a current or non-current asset, as appropriate.
Unrealized holding gains and losses for all available-for-sale securities are
reported net, as a separate component of other comprehensive income, a part of
stockholders' equity, until the gains and losses are realized.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
     Wessex uses cross-currency and interest rate swaps for the purpose of
hedging specific exposures as part of its risk management program and holds all
derivatives for purposes other than trading. Deferral (hedge) accounting is
applied only if the derivative reduces the risk of the underlying hedged item
and is designated at inception as a hedge with respect to the underlying hedged
item. Additionally, the derivative must result in cash flows that are expected
to be inversely correlated to those of the underlying hedged item. Under hedge
accounting, the changes in market value of the derivatives and the hedged assets
or liabilities are deferred and recognized in net income in the same period. If
Wessex's use of derivatives did not qualify for hedge accounting treatment, the
derivative would be recorded at fair value with changes in fair value recognized
in net income.
 
EARNINGS PER SHARE
 
     Basic earnings per share is based on the earnings from continuing
operations available to common stockholders divided by the weighted average
number of shares outstanding during each period. Diluted earnings per share is
calculated in the same manner as basic earnings per share except that the
numerator is increased by the amount of dividends payable to the holders of
convertible securities and the denominator is increased, using the treasury
stock method, to include the number of additional ordinary shares that would
have been outstanding, assuming the exercise of all employee stock options and
the conversion of all convertible securities that would have had a dilutive
effect on basic earnings per share.
 
ENVIRONMENTAL COSTS
 
     Environmental expenditures that relate to current operations are expensed.
Expenditures providing a future benefit are capitalized as appropriate.
Remediation costs that relate to an existing condition caused by past operations
are accrued when it is probable that these costs will be incurred and can be
reasonably estimated.
 
STOCK-BASED COMPENSATION
 
     Wessex follows Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" ("APB 25"), and related interpretations in accounting
for its employee stock options. Under APB 25, compensation expense is recorded
when the exercise price of employee stock options is less than the fair value of
the underlying stock on the measurement date.
 
ACCOUNTING STANDARDS ISSUED
 
     In June 1998, the FASB issued SFAS 133 "Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. SFAS 133 requires
that an entity recognize all derivatives as either assets or liabilities in the
balance sheet at fair value. SFAS 133 is effective for all fiscal quarters of
fiscal years beginning after

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
June 15, 1999. Wessex is currently evaluating, and has not yet determined, the
effect that the adoption of SFAS 133 will have on its financial statements.
 
     In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of
Start-Up Activities," which requires that costs for start-up activities and
organization costs be expensed as incurred and not capitalized as had previously
been allowed. SOP 98-5 is applicable to all financial statements for fiscal
years beginning after December 15, 1998 and initial adoption is required to be
reflected as a cumulative effect of an accounting change. The adoption of SOP
98-5 is not expected to have a material effect on Wessex's financial position or
results of operations.

     The three EIB currency term loans which are due and payable from 1998
through June 2002 have both fixed and variable interest rates in their
respective currencies with semiannual interest payments. Using a combination of
interest rate swaps and currency swaps these rates are changed to variable and
fixed GBP interest rates.
    
 
     Wessex's term loans and credit facilities are subject to certain financial
covenants, including the maintenance of minimum interest cover, maximum gearing
levels and minimum net worth.
 
NOTE 10 -- FINANCIAL INSTRUMENTS
 
     Wessex uses a variety of financial instruments denominated in foreign
currencies, at both floating and fixed interest rates, to finance its
operations. Wessex manages the risk arising on these instruments by entering
into cross-currency and interest rate swaps.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     The carrying amount of short-term financial instruments including cash and
cash equivalents, accounts receivable, accounts payable, and all other
short-term financial assets and liabilities, including bank debt, approximates
fair value due to the short maturity of those instruments.
 
     The fair value of preference shares with mandatory redemption requirements
and long-term debt are estimated using discounted cash flow analyses based on
Wessex's current incremental financing rates for similar types of securities.
The fair value of currency swaps and interest rate swaps was determined based on
a model which estimates the fair value of these swap contracts using market
rates at March 31, 1998 or was based on quoted market prices for similar
instruments with similar maturities. A comparison of the carrying value and fair
value of these instruments is included below:

     Wessex is exposed to credit risk in the event of non-performance by
counterparties to interest rate and cross-currency swap contracts. However,
because Wessex deals only with major commercial banks with high-quality credit
ratings, it does not anticipate non-performance by any of these counterparties.
 
     Wessex is exposed to market risk in the form of foreign exchange rate and
interest rate risks. Wessex has one consolidated foreign subsidiary, which has a
functional currency of Swiss francs. On consolidation the functional currency
accounts are translated to the reporting currency with translation gains and
losses recorded in other comprehensive income. Wessex has several variable and
fixed rate loans in foreign currencies which are fully hedged through a
combination of cross-currency swaps and interest rate swaps. In addition, Wessex
is subject to foreign currency risk on translation from its functional currency
(GBP) to the reporting currency (USD).

PROFIT-SHARING STOCK PLAN
 
     Wessex operates a profit-sharing stock plan whereby employees can apply for
free shares and also purchase shares. If the employee purchases shares, Wessex
matches the number of shares purchased up to a set limit. The fair market value
of the free and matching shares on the grant date is written off to the income
statement in the year of issue. Employees are entitled to all dividends on these
shares when issued. At March 31, 1998, 452,623 ordinary shares were held by
Wessex Water Trustee Company Ltd on behalf

originally redeemable at par in four equal tranches on the dividend payment date
in each of the years 1998, 1999, 2000 and 2001. The preference dividend is paid
annually in arrears at a gross dividend rate, fixed in advance, of 12 month
LIBOR plus 0.5%. Preference shares have priority on winding up, but are
non-voting unless a resolution is passed to vary their rights.
 
     Beginning in September 1998, Wessex redeemed all of its 308,984,402
cumulative redeemable preference shares at the par value of 50p per share. This

November 23, 1998 to cancel the preference shares by repaying capital to the
preference stockholders.

NOTE 15 -- PENSIONS
 
     The defined benefit schemes which cover the majority of staff are the
Wessex Water Pension Scheme ("WWPS"), the Wessex Water Mirror Image Pension
Scheme ("WWMIS") and the Wessex Water Executive Pension Scheme ("WWEPS"). The
assets are held in separate trustee-administered funds. The pension cost charged
to the income statement has been determined on the advice of independent
qualified actuaries and is accrued over the service lives of the employees
expected to be eligible to receive such benefits.
 
     The following assumptions were used in determining the funded status and
pension charge for each period, and are determined as of the beginning of the
period:

NOTE 16 -- SEGMENT AND GEOGRAPHIC INFORMATION
 
     Wessex's principal business is the provision of water supply and wastewater
services in southwestern England. For management reporting purposes the
operations are divided into three service categories: regulated water services,
unregulated water services and SC Technology. Regulated water services accounted
for approximately 91%, 93% and 93% of revenues for the six months ended October
2, 1998, and for the years ended March 31, 1998 and 1997, respectively. Wessex's
management regularly reviews financial information relating to these three
service categories. The financial information provided to and reviewed by the
chief operating decision maker does not include balance sheet information by
segment. The financial management information is prepared using UK generally
accepted accounting principles which differ in certain significant respects from
US generally accepted accounting principles.

     On Friday July 24, 1998 Enron Corp. ("Enron") of Houston, Texas, United
States, made a cash offer of 630p per share for the shares of Wessex. This offer
was recommended to the stockholders by the Board of Directors of Wessex. The
offer ran to August 28, 1998, but was extended to September 18, 1998 to allow
the Secretary of State for Trade and Industry to consider if there should be an
investigation by the Monopolies and Mergers Commission ("MMC"). On September 10,
1998 it was announced that there would be no reference to the MMC. On September
21, 1998 Enron announced that the offer had become unconditional, having
received by September 18, 1998 acceptances representing 87.2 percent of all
ordinary shares.
 
     On October 2, 1998 Enron announced that it had received acceptances
representing more than 90 percent of all ordinary shares. On that same date
notices were issued to the remaining Wessex ordinary shareholders, informing
them that Enron intended to exercise its rights under Section 429 of the
Companies Act 1985 to acquire compulsorily all of the outstanding ordinary
shares. The compulsory share acquisition was completed in November 1998. Offer
documents were also sent to the stock option holders in the Savings-Related
Share Option Scheme. The options outstanding under this scheme and the Executive
Share Option Scheme were either exercised and the shares acquired by Enron, or
compensation was paid to settle the liabilities under the schemes. All stock
option schemes are now closed.
 
     On November 30, 1998, Wessex sold its interest in Wessex Waste Management
Ltd to Waste Management International for $337.9 million.
 
     In December 1998, all of the remaining 128,339,909 redeemable preference
shares were redeemed and Wessex Water Plc changed its name to Wessex Water Ltd.

the U.S. underwriters against some liabilities, including some liabilities under
the Securities Act, or to contribute to payments
    
<PAGE>   172
 
the international managers and the U.S. underwriters may be required to make in
respect of those liabilities.
 
   
     The shares of common stock are being offered by the underwriters, subject
to prior sale, when, as and if issued to and accepted by them, subject to
approval of legal matters by counsel for the underwriters and certain other
conditions. The underwriters reserve the right to withdraw, cancel or modify
offers and to reject orders in whole or in part.
    
 
COMMISSIONS AND DISCOUNTS
 
   
     The lead managers have advised Azurix and the selling stockholder that the
international managers propose initially to offer the shares of our common stock
to the public at the initial public offering price set forth on the cover page
of this prospectus, and to certain dealers at such price less a concession not
in excess of $     per share of common stock. The international managers may
allow, and such dealers may reallow, a discount not in excess of $     per share
of common stock to certain other dealers. After the initial public offering, the
public offering price, concession and discount may be changed.
    
 
     The following table shows the per share and total public offering price,
the underwriting discount to be paid by Azurix and the selling stockholder to
the international managers and the U.S. underwriters and the proceeds before
expenses to Azurix and the selling stockholder. This information is presented
assuming either no exercise or full exercise by the international managers and
the U.S. underwriters of their over-allotment options.

INTERSYNDICATE AGREEMENT
 
     The international managers and the U.S. underwriters have entered into an
intersyndicate agreement that provides for the coordination of their activities.
Under the terms of the intersyndicate agreement, the international managers and
the U.S. underwriters are permitted to sell shares of common stock to each other
for purposes of resale at the public offering price, less an amount not greater
than the selling concession. Under the terms of the intersyndicate agreement,
the U.S. underwriters and any dealer to whom they sell shares of our common
stock will not offer to sell or sell shares of common stock to persons who are
non-U.S. or non-Canadian persons or to persons they believe intend to resell to
persons who are non-U.S. or non-Canadian persons, and the international managers
and any dealer to whom they sell shares of common stock will not offer to sell
or sell shares of common stock to U.S. persons or to Canadian persons or to
persons they believe intend to resell to U.S. persons or Canadian persons,
except in the case of transactions under the terms of the intersyndicate
agreement.
 
OVER-ALLOTMENT OPTION
 
     The selling stockholder has granted an option to the international
managers, exercisable for 30 days after the date of this prospectus, to purchase
up to an aggregate of             additional shares of our common stock at the
public offering price set forth on the cover page of this prospectus, less the
underwriting discount. The international managers may exercise this option
solely to cover over-allotments, if any, made on the sale of our common stock
offered hereby. To the extent that the international managers exercise this
option, each international manager will be obligated, subject to certain
conditions, to purchase a number of additional shares of our common stock
proportionate to such international manager's initial amount reflected in the
foregoing table.
<PAGE>   173
 
     The selling stockholder also has granted an option to the U.S.
underwriters, exercisable for 30 days after the date of this prospectus, to
purchase up to an aggregate of             additional shares of common stock to
cover over-allotments, if any, on terms similar to those granted to the
international managers.
 
RESERVED SHARES
 
     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to             of the shares offered hereby to be sold
to some of our directors, officers, employees, customers and other persons with
whom we have an existing relationship who have expressed an interest in
purchasing our common stock, including certain employees, officers and directors
of Enron and its affiliated companies, business associates and related persons.
The number of shares of our common stock available for sale to the general
public will be reduced to the extent that those persons purchase the reserved
shares. Any reserved shares which are not orally confirmed for purchase within
one day of the pricing of the offering will be offered by the underwriters to
the general public on the same terms as the other shares offered by this
prospectus.
 
NO SALES OF SIMILAR SECURITIES
 
   
     Azurix and the selling stockholder have agreed, with certain exceptions,
not to directly or indirectly engage in the following activities for a period of
180 days after the date of this prospectus without the prior written consent of
Merrill Lynch, Pierce, Fenner & Smith Incorporated:
    
 
   
     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of our common stock or securities convertible into or
       exchangeable or exercisable for or repayable with our common stock,
       whether now owned or later acquired by the person executing the agreement
       or with respect to which the person executing the agreement later
       acquires the power of disposition, or file a registration statement under
       the Securities Act relating to any shares of our common stock
    
 
   
     - Enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of our common stock whether
       any such swap or transaction is to be settled by delivery of our common
       stock or other securities, in cash or otherwise, see "Shares Eligible for
       Future Sale"
    
 
   
     As an exception to these restrictions we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors -- Future sales of our common stock
may depress our stock price."
    
 
NEW YORK STOCK EXCHANGE LISTING
 
   
     Azurix is applying to list the common stock on the New York Stock Exchange
under the symbol "AZX." In order to meet the requirements for listing of our
common stock on that exchange, the underwriters have undertaken to sell lots of
100 or more shares to a minimum of 2,000 beneficial owners.
    
 
   
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations among
Azurix, the selling stockholder, Enron, the lead managers and the U.S.
representatives. The factors to be considered in determining the initial public
offering price, in addition to prevailing market conditions, are the valuation
multiples of publicly traded companies that the lead managers and the U.S.
representatives believe to be comparable to us, including adjusted market value
to EBITDA multiples, price to book value multiples and price to earnings
multiples, certain of our financial information, the history of, and the
prospects for, our company and the industry in which we compete, an assessment
of our management, our past and present operations, the prospects for and timing
of our future revenues, the present state of our development, and the above
factors in relation
    
<PAGE>   174
 
   
to market values and various valuation measures of other companies engaged in
activities similar to ours. There can be no assurance that an active trading
market will develop for the common stock or that the common stock will trade in
the public market subsequent to this offering at or above the initial public
offering price.
    
 
   
     The underwriters do not expect sales of our common stock to any accounts
over which they exercise discretionary authority to exceed 5% of the number of
shares being offered in this offering.
    
 
   
PRICE STABILIZATION AND SHORT POSITIONS
    
 
   
     Until the distribution of our common stock is completed, rules of the SEC
may limit the ability of the underwriters and selling group members to bid for
and purchase our common stock. As an exception to these rules, the lead managers
and the U.S. representatives are permitted to engage in certain transactions
that stabilize the price of our common stock. Such transactions consist of bids
or purchases for the purpose of pegging, fixing or maintaining the price of our
common stock.
    
 
   
     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the lead managers and
the U.S. representatives may reduce that short position by purchasing our common
stock in the open market. The lead managers and the U.S. representatives may
also elect to reduce any short position by exercising all or part of the
over-allotment option described above.
    
 
   
PENALTY BIDS
    
 
     The lead managers and the U.S. representatives may also impose a penalty
bid on underwriters and selling group members. This means that if the lead
managers or the U.S. representatives purchase shares of our common stock in the
open market to reduce the underwriters' short position or to stabilize the price
of our common stock, they may reclaim the amount of the selling concession from
the underwriters and selling group members who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
     None of Azurix, the selling stockholder, or any of the underwriters makes
any representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of our common stock.
In addition, none of Azurix, the selling stockholder, or any of the underwriters
makes any representation that the lead managers or the U.S. representatives will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
 
OTHER RELATIONSHIPS
 
   
     Some of the underwriters and their affiliates engage in transactions with,
and perform services for, our company, Enron and Enron's affiliates in the
ordinary course of business and have engaged, and may in the future engage, in
commercial banking and investment banking transactions and services with our
company, Enron and Enron's affiliates, for which they have received customary
compensation.
    
 
STAMP TAXES
 
     Purchasers of the shares of common stock offered hereby may be required to
pay stamp taxes and other charges in accordance with the laws and practices of
the country of purchase in addition to the offering price set forth on the cover
page hereof.

       document may otherwise lawfully be issued or passed on.

stock, or the possession, circulation or distribution of this prospectus or any
other material relating to us or shares of our common stock in any jurisdiction
where action for that purpose is required. Accordingly, the shares of our common
stock may not be offered or sold, directly or indirectly, and neither this

regulations of any such country or jurisdiction.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law ("DGCL") provides that
a corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal, administrative or investigative (other than
an action by or in the right of the corporation by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Section 145 further
provides that a corporation similarly may indemnify any such person serving in
any such capacity who was or is a party or is threatened to be made a party to
any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all of the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Delaware Court of Chancery or such other
court shall deem proper.
 
     Azurix's certificate of incorporation and bylaws provide that
indemnification shall be to the fullest extent permitted by the DGCL for all
current or former directors or officers of the company.
 
     As permitted by the DGCL, the certificate of incorporation provides that
directors of Azurix shall have no personal liability to Azurix or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except (1) for any breach of the director's duty of loyalty to Azurix or its
stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violations
                                      II-1

of law, (3) under Section 174 of the DGCL or (4) for any transaction from which
a director derived an improper personal benefit.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
     On January 29, 1998, Azurix issued 1,000 shares to Enron in an exempt
transaction pursuant to Section 4(2) of the Securities Act.

     (a) Exhibits. See the Exhibit Index following the signature pages to this

     (b) Financial Statement Schedules. See Reports of Independent Public

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes:
 
          (a) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the Registrant pursuant to the provisions described
     in Item 14, or otherwise, the Registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the Registrant of expenses incurred
     or paid by a director, officer or controlling person of the Registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the Registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act and
     will be governed by the final adjudication of such issue.
 
          (b) To provide to the underwriter(s) at the closing specified in the
     underwriting agreements, certificates in such denominations and registered
     in such names as required by the underwriter(s) to permit prompt delivery
     to each purchaser.
 
          (c) For purpose of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.
 
          (d) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant has duly caused this Amendment No. 1 to Registration Statement to be

of Houston, in the State of Texas, on May 5, 1999.

                        ON FINANCIAL STATEMENT SCHEDULES
    
 
To the stockholder of Azurix Corp.:
 
   
     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Azurix Corp. and subsidiaries as of
December 31, 1998 and for the period from January 29, 1998 (Date of Inception)
to December 31, 1998 included in this registration statement and have issued our
report thereon dated February 22, 1999. Our audit was made for the purpose of
forming an opinion on the basic financial statements taken as a whole. Schedule
I and Schedule II (as related to Azurix Corp. for the period from January 29,
1998 (Date of Inception) to December 31, 1998) listed in Item 16(b) are the
responsibility of Azurix Corp.'s management and are presented for purposes of
complying with the Securities and Exchange Commission's rules and are not part
of the basic financial statements. These schedules have been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, fairly state in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

     We have audited in accordance with generally accepted auditing standards,
the consolidated statements of income, changes in stockholders' equity and cash

made for the purpose of forming an opinion on the basic financial statements
taken as a whole. Schedule II listed in Item 16(b) as related to Wessex Water
Ltd (formerly Wessex Water Plc) for the period from April 1, 1998 to October 2,
1998 is the responsibility of the company's management and is presented for
purposes of complying with the Securities and Exchange Commission's rules and is
not part of the basic financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic financial statements
and, in our opinion, fairly states in all material respects the financial data

To the stockholder of Wessex Water Ltd (formerly Wessex Water Plc)
    
 
   
In connection with our audits on the consolidated financial statements of Wessex
Water Plc (now renamed Wessex Water Ltd) and its subsidiaries (the "Company") at
March 31, 1998 and for each of the two years in the period ended March 31, 1998,
which financial statements are included in this Registration Statement, we have
also audited Schedule II listed in Item 16(b) as it relates to Wessex Water Ltd
(formerly Wessex Water Plc) for each of the two years in the period ended March
31, 1998. In our opinion, this financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly, in
all material respects, the information required to be included therein.

portion of any Option or Restricted Stock granted or offered under the Plan can
no longer under any circumstances be exercised, or (b) any shares of Common
Stock are reacquired by the Company pursuant to an Incentive Option Agreement,

combination of shares, reclassification, stock dividend, or other change in the
capital structure of the Company, then appropriate adjustments shall be made by
the Administrator to the aggregate number and kind of shares subject to this
Plan, and the number and kind of shares and the price per share subject to
outstanding Option Agreements, Restricted Stock Agreements in order to preserve,
as nearly as practical, but not to increase, the benefits to Participants.
Further, if an equity capital contribution is made to the Company, stockholders
and Plan Participants will experience a dilution in their shares of Common
Stock, Options, rights to acquire Restricted Stock by the amount of such
contribution. For example, if there are 30 million shares of Common Stock
outstanding, and the Fair Market Value is $1/share, and an equity contribution
of 30 million dollars is made, the total number of shares of Common Stock
outstanding would increase to 60 million shares and the per share Fair Market
Value would remain $1.

                                     OPTIONS

         5.1   Option Agreement. Each Option granted pursuant to this Plan shall
be evidenced by an Option Agreement which shall specify the number of shares
subject thereto, vesting provisions relating to such Option, the Exercise Price
per share, and whether the Option is an Incentive Option or Nonqualified Option.
As soon as is practical following the grant of an Option, an Option Agreement
shall be duly executed and delivered by or on behalf of the Company to the
Optionee to whom such Option was granted. Each Option Agreement shall be in such
form and contain such additional terms and conditions, not inconsistent with the
provisions of this Plan, as the Administrator shall, from time to time, deem
desirable. Each Option Agreement may be different from each other Option
Agreement.

         5.2   Exercise Price. The Exercise Price per share of Common Stock
covered by each Option shall be determined by the Administrator, subject to the
following: (a) the Exercise Price of an Incentive Option shall not be less than
100% of Fair Market Value on the date the Incentive Option is granted, (b) the
Exercise Price of a Nonqualified Option shall not be less than 100% of Fair
Market Value on the date the Nonqualified Option is granted, and (c) if the
person to whom an Option is granted is a 10% Shareholder on the date of grant,
the Exercise Price of an Incentive Option shall not be less than 110% of Fair
Market Value on the date the Option is granted.

         5.3   Payment of Exercise Price. Payment of the Exercise Price shall be
made upon exercise of an Option and may be made, in the discretion or the
Administrator, subject to any legal restrictions, by: (a) cash; (b) check; (c)
the surrender of shares of Common Stock owned by the Optionee that have been
held by the Optionee for at least six (6) months, which surrendered shares shall
be valued at Fair Market Value as of the date of such exercise; (d) the
Optionee's promissory note in a form and on terms acceptable to the
Administrator; (e) the cancellation of indebtedness of the Company to the
Optionee; (f) the waiver of compensation due or accrued to the Optionee for
services rendered; (g) provided that a public market for the Common Stock
exists, a "same day sale" commitment from the Optionee and an NASD Dealer
whereby the Optionee irrevocably elects to exercise the Option and to sell a
portion of the shares so purchased to pay for the Exercise Price and whereby the
NASD Dealer irrevocably commits upon receipt of such shares to forward the
Exercise Price directly to the Company; (h) provided that a public market for
the Common Stock exists, a "margin" commitment from the Optionee and an NASD

                                       5

<PAGE>   6

Dealer whereby the Optionee irrevocably elects to exercise the Option and to
pledge the shares so purchased to the NASD Dealer in a margin account as
security for a loan from the NASD Dealer in the amount of the Exercise Price,
and whereby the NASD Dealer irrevocably commits upon receipt of such shares to
forward the Exercise Price directly to the Company; or (i) any combination of
the foregoing methods of payment or any other consideration or method of payment
as shall be permitted by applicable corporate law and acceptable to the
Administrator.

         5.4   Term and Termination of Options. The term and provisions for
termination of each Option shall be as fixed by the Administrator, but no Option
may be exercisable more than ten (10) years after the date it is granted.

         5.5   Vesting and Exercise of Options. Each Option shall vest and 
become exercisable in one or more installments at such time or times, and
subject to such conditions for accelerated vesting, including without limitation
the achievement of specified performance goals or objectives, as shall be
determined by the Administrator.

         5.6   Annual Limit on Incentive Options. To the extent required for
"incentive stock option" treatment under Section 422 of the Code, the aggregate
Fair Market Value (determined as of the time of grant) of the Common Stock shall
not, with respect to which Incentive Options granted under this Plan and any
other plan of the Company or any Affiliated Company become exercisable for the
first time by an Optionee during any calendar year, exceed $100,000.

         5.7   Nontransferability of Options. No Option shall be assignable or
transferable except by will or the laws of descent and distribution, and during
the life of the Optionee shall be exercisable only by such Optionee; provided,
however, that, in the discretion of the Administrator, an Option may be assigned
or transferred in any manner which any such option is permitted to be assigned
or transferred under the Code.

         5.8   Rights as Shareholder. An Optionee or permitted transferee of an
Option shall have no rights or privileges as a shareholder with respect to any
shares covered by an Option until such Option has been duly exercised and
certificates representing shares purchased upon such exercise have been issued
to such person.

         5.9   Restrictions on Underlying Shares of Common Stock. Shares of 
Common Stock issued pursuant to the exercise of an Option may not be sold,
assigned, transferred, pledged or otherwise encumbered or disposed of except as
specifically provided in the Option Agreement.

                                RESTRICTED STOCK

         6.1   Grants of Restricted Stock. A grant of Restricted Stock pursuant
to a Restricted Stock Agreement entitles the recipient to acquire shares of
Common Stock subject to such terms, restrictions and conditions as the
Administrator may determine at the time of grant. Such conditions may include,
but are not limited to, continued employment and/or the achievement of specified
performance goals or objectives, if any.

         6.2   Restricted Stock Agreement. Each Restricted Stock Agreement shall
be in such form, and shall set forth the terms, conditions and restrictions of
the Restricted Stock, not inconsistent with the provisions of this Plan, as the
Administrator shall, from time to time, deem desirable. Each Restricted Stock
Agreement may be different from each other Restricted Stock Agreement.

         6.3   Rights as a Shareholder. Upon becoming vested in Restricted 
Stock, a Participant shall have the rights of a shareholder with respect to the
Restricted Stock granted pursuant to the Restricted Stock Agreement, including
voting and dividend rights, subject to the terms, restrictions and conditions as
are set forth herein and in the Restricted Stock Agreement. Unless the
Administrator shall determine otherwise, certificates evidencing shares of
Restricted Stock shall remain in the possession of the Company until such shares
have vested and are no longer subject to any restrictions on transfer in
accordance with the terms of the Restricted Stock Agreement.

         6.4   Restrictions. Shares of Restricted Stock may not be sold, 
assigned, transferred, pledged or otherwise encumbered or disposed of except as
specifically provided in the Restricted Stock Agreement.

         6.5   Vesting of Restricted Stock. The Restricted Stock Agreement shall
specify the date or dates, the performance goals or objectives that must be
achieved, if any, and any other conditions on which the Restricted Stock may
vest.

         6.6   Dividends. All dividends and distributions, or cash equivalent
thereof (whether cash, stock or otherwise), on unvested Restricted Stock shall
be withheld from the respective Participant and credited by the Company for the
Participant's account. At such time as a Participant becomes vested in a portion
of the grant of Restricted Stock, all accumulated credits for dividends and
distributions, or cash equivalent thereof attributable to such vested Restricted
Stock shall be released to the Participant. Interest shall not be paid on any
dividends or distributions or cash equivalent thereof, credited by the Company
for the account of a Participant. The Company shall have the option of paying
such credits for accumulated dividends or distributions or cash equivalent
thereof, in shares of Common Stock of the Company rather than in cash. If
payment is made in shares, the conversion to shares shall be at the Fair Market
Value. Dividends and distributions, or cash equivalent thereof credited on
non-vested Restricted Stock shall be forfeited in the same manner and at the
same time as the respective shares of Restricted Stock to which they are
attributable are forfeited.

         6.7   Nonassignability of Rights. No Participant's right to acquire
shares of Restricted Stock shall be assignable or transferable except by will or
the laws of descent and distribution or as otherwise provided by the
Administrator.

                           ADMINISTRATION OF THE PLAN

         7.1   Administrator. Authority to control and manage the operation and
administration of the Plan shall be vested in the Board, which may delegate such
responsibilities in whole or in part to a committee consisting of two (2) or
more members of the Board (the "Committee" or "Administrator"). Members of the
Committee may be appointed from time to time by, and shall serve at the pleasure
of, the Board.

         7.2   Powers of the Administrator. In addition to any other powers or
authority conferred upon the Administrator elsewhere in the Plan or by law, the
Administrator shall have full power and authority: (a) to determine the persons
to whom, and the time or times at which, Incentive Options or Nonqualified
Options and awards of Restricted Stock shall be granted, the number of shares to
be represented by each Option and grant of Restricted Stock and the
consideration, if any, to be received by the Company upon the exercise thereof;
(b) to construe and interpret provisions of the Plan and other documents and
agreements pertaining to the Plan; (c) to create, amend or rescind rules and
regulations relating to the Plan; (d) to determine the terms, conditions and
restrictions contained in, and the form of, Option Agreements and Restricted
Stock Agreements; (e) to determine the identity or capacity of any persons who
may be entitled to exercise a Participant's rights under any Option or
Restricted Stock Agreement granted under the Plan; (f) to correct any defect or
supply any omission or reconcile any inconsistency in the Plan or in any Option
Agreement or Restricted Stock Agreement; (g) to accelerate the vesting of any
Option or grant of Restricted Stock; (h) to extend the exercise date of any
Option and vesting date of any grant of Restricted Stock; (i) to amend
outstanding Option Agreements and Restricted Stock Agreements to provide for,
among other things, any change or modification which the Administrator could
have provided for upon the grant of an Option or Restricted Stock or in
furtherance of the powers provided for herein; and (j) to make all other
determinations necessary or advisable for the administration of the Plan, but
only to the extent not contrary to the express provisions of the Plan. Any
action, decision, interpretation or determination made in good faith by the
Administrator in the exercise of its authority conferred upon it under the Plan
shall be final and binding on the Company and all Participants.

         7.3   Limitation on Liability. No employee of the Company or member of
the Board or Committee shall be subject to any liability with respect to duties
under the Plan unless the person acts fraudulently or in bad faith. To the
extent permitted by law, the Company shall indemnify each member of the Board or
Committee, and any employee of the Company with duties under the Plan, who was
or is a party, or is threatened to be made a party, to any threatened, pending
or completed proceeding, whether civil, criminal, administrative or
investigative, by reason of such person's conduct in the performance of duties
under the Plan.

                                CHANGE IN CONTROL

         8.1   Change in Control of Enron Corp. If at any time after the date 
the Plan is adopted when:

(a)      if a public offering of Common Stock has not yet occurred, fifty
         percent (50%) or more of the Directors of the Company have been

(b)      if a public offering of Common Stock has occurred, Enron Corp. directly
         or indirectly owns thirty percent (30%) or more of the capital stock of
         the Company,

a transaction occurs which is not approved, recommended or supported by a
majority of the board of directors of Enron Corp. in actions taken prior to, and
with respect to, such transaction in which:

(i)      Enron Corp. merges or consolidates with any other entity (other than

         Beneficial Owner of at least thirty percent (30%) of the outstanding
         capital stock of Enron Corp., or

(v)      the individuals who constitute the members of Enron Corp.'s board of
         directors on the date hereof (the "Incumbent Board") cease for any
         reason to constitute at least a majority thereof, provided that any
         person becoming a director subsequent to the date hereof whose election
         or nomination for election by Enron Corp.'s stockholders was approved
         by a vote of at least eighty percent (80%) of the directors comprising
         the Incumbent Board (either by a specific vote or by approval of the
         proxy statement of Enron Corp. in which such person is named as a
         nominee for director, without objection to such nomination) shall be,
         for purposes of this clause (v), considered as though such person were
         a member of the Incumbent Board,

then within (a) ten days of the approval by the stockholders of Enron Corp. of
such merger, consolidation, sale of assets or dissolution as described in clause
(i), (ii) or (iii) of this Section 8.1, or (b) thirty (30) days of the
occurrence of such change of Beneficial Ownership or Directors as described in
clause (iv) or (v) of this Section 8.1, with respect to outstanding grants of

Company by each grantee thereof and such grants shall thereupon be canceled by
the Company, and the grantee shall receive a

<PAGE>   10


cash payment by the Company in an amount equal to the number of Shares subject
to the grant of Restricted Stock held by such grantee multiplied by the Fair
Market Value of a Share on the date determined by the Administrator (as
constituted prior to any change described in clause (iv) or (v)) to be the date
of cancellation and surrender of such Options if any such change of Beneficial
Ownership or Directors occurs other than pursuant to a tender or exchange offer,
whichever is appropriate, and with respect to outstanding grants of Options made
under Article 5, all such outstanding Options irrespective of whether they are
then exercisable, shall be surrendered (at such time as may be necessary to
comply with Rule 16b-3 under the Securities Exchange Act of 1934, as amended, if
applicable) to the Company by each grantee thereof and such Options shall
thereupon be cancelled by the Company, and the grantee shall receive a cash
payment by the Company in an amount equal to the number of Shares subject to the
Options held by such grantee multiplied by the difference between (x) and (y)
where (y) equals the purchase price per Share covered by the Option, and (x)
equals the Fair Market Value of a Share on the date determined by the
Administrator (as constituted prior to any change described in clause (iv) or
(v)) to be the date of cancellation and surrender of such Options if any such
change of Beneficial Ownership or directors occurs other than pursuant to a
tender or exchange offer, whichever is appropriate.

         8.2   Change in Control of the Company. If a transaction occurs after 
the date the Plan is adopted in which:


(a)      any person or entity (other than Enron Corp., persons and entities
         owning through Enron Corp., or the trustee or committee of any
         qualified employee benefit plan of the Company or Enron Corp., or
         Marlin Water Trust or Atlantic Water Trust), together with its
         subsidiaries and Associates, shall be, directly or indirectly, the
         Beneficial Owner of (i) more than fifty percent (50%) of the
         outstanding voting stock of the Company at a time before a public
         offering of Common Stock has occurred, or (ii) at least thirty percent
         (30%) of the outstanding voting stock of the Company at a time after a
         public offering of Common Stock has occurred, unless that person or
         entity, together with its subsidiaries and Associates, first became a
         Beneficial Owner of thirty percent (30%) or more by acquiring shares of
         Common Stock directly from the Company,

(b)      the Company sells all or substantially all of its assets to any other
         person or entity,

(e)      after a public offering of Common Stock has occurred, as a result of a
         transaction that has not been approved, recommended or supported by a
         majority of the board of directors of the Company in actions taken
         prior to, and with respect to, such transaction:

         (i)      the Company merges or consolidates with any other entity
                  (other than one of the Company's wholly owned subsidiaries)
                  and is not the surviving entity (or survives only as the
                  subsidiary of another person or entity), or

<PAGE>   11

         (ii)     the individuals who constitute the members of Company's Board
                  on the date hereof (the "Incumbent Board") cease for any
                  reason to constitute at least a majority thereof, provided
                  that any person becoming a Director subsequent to the date of
                  the public offering whose election or nomination for election
                  by the Company's stockholders was approved by a vote of at
                  least eighty percent (80%) of the Directors comprising the
                  Incumbent Board (either by a specific vote or by approval of

                  named as a nominee for Director, without objection to such
                  nomination) shall be, for purposes of this clause (ii),

such merger, consolidation, sale of assets or dissolution as described in clause
(b), (c) or (e)(i) of this Section 8.2, (b) thirty (30) days of the occurrence
of such change of Beneficial Ownership or Directors as described in clause (a)
or (e)(ii) of this Section 8.2 or the cessation of trading or listing as
described in clause (d) of this Section 8.2, then with respect to outstanding
grants of Restricted Stock made under Article 6, all such grants of Restricted
Stock, irrespective of whether they are then vested, shall be surrendered to the
Company by each grantee thereof and such grants shall thereupon be canceled by
the Company, and the grantee shall receive a cash payment by the Company in an
amount equal to the number of Shares subject to the grant of Restricted Stock
held by such grantee multiplied by the Fair Market Value of a Share on the date
determined by the Administrator (as constituted prior to any change described in
clause (a) or (d)(ii)) to be the date of cancellation and surrender of such
Options if any such change of Beneficial Ownership or Directors occurs other
than pursuant to a tender or exchange offer, whichever is appropriate, and with
respect to outstanding grants of Options made under Article 5, all such
outstanding Options, irrespective of whether they are then exercisable, shall be
surrendered (at such time as may be necessary to comply with Rule 16b-3 under
the Securities Exchange Act of 1934, as amended) to the Company by each grantee
thereof and such Options shall thereupon be canceled by the Company, and the
grantee shall receive a cash payment by the Company in an amount equal to the
number of Shares subject to the Options held by such grantee multiplied by the
difference between (x) and (y) where (y) equals the purchase price per Share
covered by the Option, and (x) equals (1) the per share price offered to
stockholders of the Company in any such merger, consolidation, sale of assets or
dissolution transaction, (2) the per share price offered to stockholders of the
Company in any tender offer or exchange offer whereby any such change of
Beneficial Ownership or Directors takes place, or (3) the Fair Market Value of a
Share on the date determined by the Administrator (as constituted prior to any
change described in clause (a) or (d)(ii)) to be the date of cancellation and
surrender of such Options if any such change of Beneficial Ownership or
Directors occurs other than pursuant to a tender or exchange offer, whichever is
appropriate. In the event that the consideration offered to stockholders of the
Company in any transaction described in this Section 8.2 consists of anything
other than cash, the Administrator (as constituted prior to such transaction)
shall determine the fair cash equivalent of the portion of the consideration
offered which is other than cash.

                      AMENDMENT AND TERMINATION OF THE PLAN

         9.1   Amendments. The Board may from time to time alter, amend, suspend
or terminate the Plan in such respects as the Board may deem advisable. No such
alteration, amendment, suspension or termination shall be made which shall
substantially affect or impair the rights of any Participant under an
outstanding Option Agreement or Restricted Stock Agreement without such
Participant's consent. The Board may alter or amend the Plan to comply with
requirements under the Code relating to Incentive Options or other types of
options which give Optionees more favorable tax treatment than that applicable
to Options granted under this Plan as of the date or its adoption. Upon any such
alteration or amendment, any outstanding Option granted hereunder may, if the
Administrator so determines and if permitted by applicable law, be subject to
the more favorable tax treatment afforded to an Optionee pursuant to such terms
and conditions.

         9.2   Plan Termination. Unless the Plan shall theretofore have been
terminated, the Plan shall terminate on the fifth (5th) anniversary of the
Effective Date and no Options or grants of Restricted Stock may be granted under
the Plan thereafter, but Option Agreements and Restricted Stock Agreements then
outstanding shall continue in effect in accordance with their respective terms
and provisions.

         9.3   Employees in Foreign Countries. The Board shall have the 
authority to adopt such modifications, procedures, and subplans as may be
necessary or desirable to comply with provisions of the laws of foreign
countries in which the Company or its Affiliated Companies may operate to assure
the viability of the benefits from grants made to eligible employees employed in
such countries and to meet the objectives of the Plan.

                                 TAX WITHHOLDING

         10.1  Withholding. The Company shall have the power to withhold, or
require a Participant to remit to the Company, an amount sufficient to satisfy
any applicable Federal, state, and local tax withholding requirements with
respect to any Options exercised or Restricted Stock issued under the Plan. To
the extent permissible under applicable tax, securities and other laws, the
Administrator may, in its sole discretion and upon such terms and conditions as
it may deem appropriate, permit a Participant to satisfy his or her obligation
to pay any such tax, in whole or in part, up to an amount determined on the
basis of the highest marginal tax rate applicable to such Participant, by (a)
directing the Company to apply shares of Common Stock to which the Participant
is entitled as a result of the exercise of an Option or as a result of the
purchase of or lapse of restrictions on Restricted Stock or (b) delivering to
the Company shares of Common Stock owned by the Participant. The shares of
Common Stock so applied or delivered in satisfaction of the Participant's tax
withholding obligation shall be valued at their Fair Market Value as of the date
of measurement of the amount of income subject to withholding.

         11.1  Benefits Not Alienable. Other than as provided above, benefits
under the Plan may not be assigned or alienated, whether voluntarily or

voluntary undertaking on of the Company and shall not be deemed to constitute a
contract between the Company and any Participant to be consideration for, or an
inducement to, or a condition of, the employment of any Participant. Nothing
contained in the Plan shall be deemed to give the right to any Participant to be
retained as an employee of the Company or any Affiliated Company or to interfere
with the right of the Company or any Affiliated Company to discharge any
Participant at any time.

         11.3  Application of Funds. Any proceeds received by the Company from
the sale of Common Stock pursuant to Option Agreements, except as otherwise
provided herein, will be used for general corporate purposes.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Employment Agreement ("Agreement"), including the attached Exhibit
"A," is entered into between ENRON CORP., a Delaware corporation, having offices
at 1400 Smith Street, Houston, Texas 77002 ("Employer"), and REBECCA P. MARK, an
individual currently residing at 6102 Crab Orchard Road, Houston, Texas 77057
("Employee"), to be effective as of May 4, 1998 (the "Effective Date").

                                   WITNESSETH:

         WHEREAS, Employee is currently employer under that certain Employment
Agreement between Enron Development Corp. and Rebecca P. Mark, effective January
1, 1996.

         WHEREAS, Employee is willing to continue her employment with Employer
under the terms and conditions set forth in this Employment Agreement which
shall supersede all previous agreements; and

         NOW, THEREFORE, for and in consideration of the mutual promises,
covenants, and obligations contained herein, Employer and Employee agree as
follows:

ARTICLE 1:   EMPLOYMENT AND DUTIES:

         1.1 Employer agrees to employ Employee, and Employee agrees to be
employed by Employer, beginning as of the Effective Date and continuing until
the date set forth on Exhibit "A" (the "Term"), subject to the terms and
conditions of this Agreement.

         1.2 Employee initially shall be employed in the position set forth on
Exhibit A. Employer may subsequently assign Employee to a different position or
modify Employee's duties and responsibilities; provided however, in the event
(a) Employer substantially reduces the duties or responsibilities of Employee,
or (b) Ken Lay is no longer Chairman of Enron Corp., Employee may elect to
terminate this Agreement under Section 3.2(ii) and said termination shall
constitute an Involuntary Termination for purposes of Section 3.5. Moreover,
Employer may assign this Agreement and Employee's employment to Enron or any
affiliates of Enron. Employee agrees to serve in the assigned position and to
perform diligently and to the best of Employee's abilities the duties and
services appertaining to such position as determined by Employer, as well as
such additional or different duties and services appropriate to such position
which Employee from time to time may be reasonably directed to perform by
Employer. Employee shall at all times comply with and be subject to such
policies and procedures as Employer may establish from time to time.
Notwithstanding any other provision of this Agreement, during the Term, Employee
shall be a member of the Enron Corp. Office of the Chairman.

         1.3 Employee shall, during the period of Employee's employment by
Employer, devote Employee's full business time, energy, and best efforts to the
business and affairs of Employer and its affiliates, including the formation of
a potential new water company. Employee may not engage, directly or indirectly,
in any other business, investment, or activity 




                                       1
<PAGE>   2

that interferes with Employee's performance of Employee's duties hereunder, is
contrary to the interests of Employer or Enron, or requires any significant
portion of Employee's business time.

         1.4 In connection with Employee's employment by Employer, Employer
shall endeavor to provide Employee access to such confidential information
pertaining to the business and services of Employer as is appropriate for
Employee's employment responsibilities. Employer also shall endeavor to provide
to Employee the opportunity to develop business relationships with those of
Employer's clients and potential clients that are appropriate for Employee's
employment responsibilities.

         1.5 Employee acknowledges and agrees that, at all times during the
employment relationship Employee owes fiduciary duties to Employer, including
but not limited to the fiduciary duties of the highest loyalty, fidelity and
allegiance to act at all times in the best interests of the Employer, to make
full disclosure to Employer of all information that pertains to Employer's
business and interests, to do no act which would injure Employer's business, its
interests, or its reputation, and to refrain from using for Employee's own
benefit or for the benefit of others any information or opportunities pertaining
to Employer's business or interests that are entrusted to Employee or that she
learned while employed by Employer. Employee acknowledges and agrees that upon
termination of the employment relationship, Employee shall continue to refrain
from using for her own benefit or the benefit of others any information or
opportunities pertaining to Employer's business or interests that were entrusted
to Employee during the employment relationship or that she learned while
employed by Employer. Employee agrees that while employed by Employer and
thereafter she shall not knowingly take any action which interferes with the
internal relationships between Employer and its employees or representatives or
interferes with the external relationships between Employer and third parties.

         1.6 It is agreed that any direct or indirect interest in, connection
with, or benefit from any outside activities, particularly commercial
activities, which interest might in any way adversely affect Employer or any of
its affiliates, involves a possible conflict of interest. In keeping with
Employee's fiduciary duties to Employer, Employee agrees that during the
employment relationship Employee shall not knowingly become involved in a
conflict of interest with Employer or its affiliates, or upon discovery thereof,
allow such a conflict to continue. Moreover, Employee agrees that Employee shall
disclose to Employer's President any facts which might involve such a conflict
of interest that has not been approved by Employer's President. Employer and
Employee recognize that it is impossible to provide an exhaustive list of
actions or interests which constitute a "conflict of interest." Moreover,
Employer and Employee recognize there are many borderline situations. In some
instances, full disclosure of facts by the Employee to Employer's President may
be all that is necessary to enable Employer or its affiliates to protect its
interests. In others, if no improper motivation appears to exist and the
interests of Employer or its affiliates have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for
Employer to terminate the employment relationship. Employer and Employee agree
that Employer's determination as to whether a conflict of interest exists shall
be conclusive. Employer reserves the right to take such action as, in its
judgment, will end the conflict.

         1.7 Employee understands and acknowledges that the terms and conditions
of this Agreement constitute confidential information. Employee shall keep
confidential the terms of 



                                       2
<PAGE>   3

this Agreement and shall not disclose this confidential information to anyone
other than Employee's attorneys, tax advisors, or as required by law. Employee
acknowledges and understands that disclosure of the terms of this Agreement
constitutes a material breach of this Agreement and could subject Employee to
disciplinary action, including without limitation, termination of employment.

ARTICLE 2:   COMPENSATION AND BENEFITS:

         2.1 Employee's monthly base salary during the Term shall be not less
than the amount set forth under the heading "Monthly Base Salary" on Exhibit A,
subject to increase at the sole discretion of the Employer, which shall be paid
in semimonthly installments in accordance with Employer's standard payroll
practice. Any calculation to be made under this Agreement with respect to
Employee's Monthly Base Salary shall be made using the then current Monthly Base
Salary in effect at the time of the event for which such calculation is made.

         2.2 While employed by Employer (both during the Term and thereafter),
Employee shall be allowed to participate, on the same basis generally as other
employees of Employer, in all general employee benefit plans and programs,
including improvements or modifications of the same, which on the effective date
or thereafter are made available by Employer to all or substantially all of
Employer's employees. Such benefits, plans, and programs may include, without
limitation, medical, health, and dental care, life insurance, disability
protection, and pension plans. Nothing in this Agreement is to be construed or
interpreted to provide greater rights, participation, coverage, or benefits
under such benefit plans or programs than provided to similarly situated
employees pursuant to the terms and conditions of such benefit plans and
programs.

         2.3 Employer shall not by reason of this Article 2 be obligated to
institute, maintain, or refrain from changing, amending, or discontinuing, any
such incentive compensation or employee benefit program or plan, so long as such
actions are similarly applicable to covered employees generally. Moreover,
unless specifically provided for in a written plan document adopted by the Board
of Directors of either Employer or Enron, none of the benefits or arrangements
described in this Article 2 shall be secured or funded in any way, and each
shall instead constitute an unfunded and unsecured promise to pay money in the
future exclusively from the general assets of Employer.

         2.4 Subject to the approval of the Compensation Committee of the Enron
Corp. Board of Directors at the May 4, 1998 meeting of the Compensation
Committee, Employee shall receive an option to purchase 100,000 shares of Enron
Corp. Common Stock. The grant shall be effective on the date approved by the
Compensation Committee and shall vest 33.3% on each of January 1, 1999, January
1, 2000 and January 1, 2001, and shall be evidenced by a grant agreement.

of Directors at the May 4, 1998 meeting of the Compensation Committee, Employee
shall receive an option to purchase 350,000 shares of Enron Corp. Common Stock.
The grant shall be effective on the date approved by the Compensation Committee

shall be evidenced by a grant agreement.

Employee's employment with Employer terminates for any reason and whether or not
Employee continues to be employed by Employer or an Affiliate of Employer.
Further, in the event of Employee's termination of employment with the Employer
for any reason prior to January 1, 2000, the unvested options shall become fully

1999, and thirty percent (30%) of said option shall become exercisable on

reason prior to January 1, 2000, the unvested options shall become fully vested.
Employee shall have the lesser of three years or the remaining term of exercise

termination of employment with the Employer for any reason during the Term of
this Agreement.

         2.8 At the first meeting of the Employer's Compensation Committee after

Restricted Stock Award Agreement dated February 12, 1996, awarding Employee
100,000 shares of the Employer's common stock to be amended to immediately vest
in and release to Employee, sixty-six and 7/10ths percent (66.7%) in said Award
and to provide that the remaining unvested shares of Restricted Stock shall be
released and vested in Employee in two equal amounts on January 31, 1999, and

without condition, regardless whether Employee's employment with Employer
terminates for any reason and weather or not Employee continues to be employed
by Employer or an Affiliate of Employer.

ARTICLE 3:    TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF SUCH
              TERMINATION:

         3.1. Notwithstanding any other provisions of this Agreement, Employer
shall have the right to terminate Employee's employment under this Agreement at
any time prior to the expiration of the Term for any of the following reasons:

         (i)  For "cause" upon the determination by the Employer's Board of
              Directors that "cause" exists for the termination of the
              employment relationship. As used in this Section 3.1(i), the term
              "cause" shall mean [a] Employee's gross negligence or willful
              misconduct in the performance of the duties and services required
              of Employee pursuant to this Agreement; [b] Employee has been
              convicted of a felony; [c] Employee has willfully refused without
              proper legal reason to perform the duties and responsibilities
              required of Employee under this Agreement which remains
              uncorrected for thirty (30) days following written notice to
              Employee by Employer of such breach; [d] Employee's involvement in
              a conflict of interest as referenced in Section 1.6 for which
              Employer makes a determination to terminate the employment of
              Employee which remains uncorrected for thirty (30) days following
              written notice to Employee by Employer of such breach; [e]
              Employee has willfully engaged in conduct that Employee knows or
              should know is materially injurious to Employer, Enron, or any of
              their respective subsidiaries; [f] Employee's material breach of
              any material provision of this Agreement or 




                                       5
<PAGE>   6

              corporate code or policy which remains uncorrected for thirty
              (30) days following written notice to Employee by Employer of
              such breach; or [g] Employee violates the Foreign Corrupt
              Practices Act or other applicable United States law as proscribed
              by Section 5.1. It is expressly acknowledged and agreed that the
              decision as to whether "cause" exists for termination of the
              employment relationship by Employer is delegated to the
              Employer's Board of Directors for determination. If Employee
              disagrees with the decision reached by Employer's Board of
              Directors, the dispute will be limited to whether Employer's
              Board of Directors reached its decision in good faith;

        (ii)  for any other reason whatsoever, with or without cause, in the
              sole discretion of the Board of Directors of Employer;

        (iii) upon Employee's death; or

        (iv)  upon Employee's becoming disabled so as to entitle Employee to
              benefits under Enron's long-term disability plan or, if Employee
              is not eligible to participate in such plan, then Employee is
              permanently and totally unable to perform Employee's duties for
              Employer as a result of any medically determinable physical or
              mental impairment as supported by a written medical opinion to the
              foregoing effect by a physician selected by Employer.

The termination of Employee's employment by Employer prior to the expiration of
the Term shall constitute a "Termination for Cause" if made pursuant to Section
3.1(i); the effect of such termination is specified in Section 3.4. The
termination of Employee's employment by Employer prior to the expiration of the
Term shall constitute an "Involuntary Termination" if made pursuant to Section
3.1(ii); the effect of such termination is specified in Section 3.5. The effect
of the employment relationship being terminated pursuant to Section 3.1(iii) as
a result of Employee's death is specified in Section 3.6. The effect of the
employment relationship being terminated pursuant to Section 3.1(iv) as a result
of the Employee becoming incapacitated is specified in Section 3.7.

         3.2  Notwithstanding any other provisions of this Agreement except
Section 8.6, Employee shall have the right to terminate the employment
relationship under this Agreement at any time prior to the expiration of the
Term of employment for any of the following reasons:

         (i)  a material breach by Employer of any material provision of this
              Agreement which remains uncorrected for 30 days following written
              notice of such breach by Employee to Employer; or

         (ii) for any other reason whatsoever, in the sole discretion of
              Employee.

The termination of Employee's employment by Employee prior to the expiration of
the Term shall constitute an "Involuntary Termination" if made pursuant to
Section 3.2(i); the effect of such termination is specified in Section 3.5. The
termination of Employee's employment by Employee prior to the expiration of the
Term shall constitute a "Voluntary Termination" if made pursuant to Section
3.2(ii); the effect of such termination is specified in Section 3.3.



                                       6

         3.3 Upon a "Voluntary Termination" of the employment relationship by
Employee prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible
shall cease and terminate as of the date of termination. Employee shall be
entitled to pro rata salary through the date of such termination, but Employee
shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

         3.4 If Employee's employment hereunder shall be terminated by Employer
for Cause prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible
shall cease and terminate as of the date of termination. Employee shall be
entitled to pro rata salary through the date of such termination, but Employee
shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

         3.5 Upon an Involuntary Termination of the employment relationship by
either Employer or Employee prior to the expiration of the Term, Employee shall
be entitled, in consideration of Employee's continuing obligations hereunder
after such termination (including, without limitation, Employee's
non-competition obligations), to receive one hundred twenty-five percent (125%)
of the then current Monthly Base Salary as if Employee's employment (which shall
cease on the date of such Involuntary Termination) had continued for the full
Term of this Agreement Employee shall not be under any duty or obligation to
seek or accept other employment following Involuntary Termination and the
amounts due Employee hereunder shall not be reduced or suspended if Employee
accepts subsequent employment. Employee's rights under this Section 3.5 are
Employee's sole and exclusive rights against Employer, Enron, or their
affiliates, and Employer's sole and exclusive liability to Employee under this
Agreement, in contract, tort, or otherwise, for any Involuntary Termination of
the employment relationship. Employee covenants not to sue or lodge any claim,
demand or cause of action against Employer for any sums for Involuntary
Termination other than those sums specified in this Section 3.5. If Employee
breaches this covenant, Employer shall be entitled to recover from Employee all
sums expended by Employer (including costs and attorneys fees) in connection
with such suit, claim, demand or cause of action.

         3.6 Upon termination of the employment relationship as a result of
Employee's death, Employee's heirs, administrators, or legatees shall be
entitled to Employee's pro rata salary through the date of such termination, but
Employee's heirs, administrators, or legatees shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.7 Upon termination of the employment relationship as a result of
Employee's incapacity, Employee shall be entitled to his or her pro rata salary
through the date of such termination, but Employee shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.8 Notwithstanding any provision herein to the contrary, upon a
termination of Employee's employment under any of the circumstances described in
Sections 3.5, 3.6 or 3.7 above, Employee shall be entitled to receive a pro-rata
annual bonus payment through the date of 




                                       7
<PAGE>   8

such termination of employment and Employee shall become fully vested in
specific grants and awards made or awarded to Employee under long term incentive
plans maintained by Employer and its affiliates.

         3.9 In all cases, the compensation and benefits payable to Employee
under this Agreement upon termination of the employment relationship shall be
offset against any amounts to which Employee may otherwise be entitled under any
and all severance plans, and policies of Employer, Enron, or its affiliates.

         3.10 Termination of the employment relationship does not terminate
those obligations imposed by this Agreement which are continuing obligations,
including, without limitation, Employee's obligations under Articles 6 and 7.

         3.11 This Agreement governs the rights and obligations of Employer and
Employee with respect to Employee's salary, bonuses, and other perquisites of
employment. Except as provided above in Section 2.5 and in Section 3.8,
Employee's rights and obligations with respect to stock options and restricted
stock are governed by Enron's Stock Option Plan and respective grant agreements
and with respect to incentive compensation payments are governed by the Award
Agreement and the Plan.

ARTICLE 4:   CONTINUATION OF EMPLOYMENT BEYOND TERM; TERMINATION AND EFFECTS OF
             TERMINATION:

         4.1 Should Employee remain employed by Employer beyond the expiration
of the Term specified on Exhibit "A," such employment shall convert to a
month-to-month relationship terminable at any time by either Employer or
Employee for any reason whatsoever, with or without cause. Upon such termination
of the employment relationship by either Employer or Employee for any reason
whatsoever, all future compensation to which Employee is entitled and all future
benefits for which Employee is eligible shall cease and terminate. Employee
shall be entitled to pro rata salary through the date of such termination, but
Employee shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

ARTICLE 5:    UNITED STATES FOREIGN CORRUPT PRACTICES ACT AND OTHER LAWS:

         5.1. Employee shall at all times comply with United States laws
applicable to Employee's actions on behalf of Employer, including specifically,
without limitation, the United States Foreign Corrupt Practices Act, generally
codified in 15 USC 78 (FCPA), as the FCPA may hereafter be amended, and/or its
successor statutes. If Employee pleads guilty to or nolo contendere or admits
civil or criminal liability under the FCPA or other applicable United States
law, or if a court finds that Employee has personal civil or criminal liability
under the FCPA or other applicable United States law, or if a court finds that
Employee committed an action resulting in any Enron entity having civil or
criminal liability or responsibility under the FCPA or other applicable United
States law with knowledge of the activities giving rise to such liability or
knowledge of facts from which Employee should have reasonably inferred the
activities giving rise to liability had occurred or were likely to occur, such
action or finding shall constitute "cause" for termination under this Agreement
unless Employer's management committee (or, if there is no management committee,
the highest applicable level of Employer's management) determines that the
actions found to be in violation of the FCPA or other applicable United States
law were taken in good faith and in compliance with all applicable policies of
Employer and Enron.

ARTICLE 6:   OWNERSHIP AND PROTECTION OF INFORMATION; COPYRIGHTS:

         6.1 All information, ideas, concepts, improvements, discoveries, and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by Employee, individually or in conjunction with others, during
Employee's employment by Employer (whether during business hours or otherwise
and whether on Employer's premises or otherwise) which relate to Employer's
business, products or services (including, without limitation, all such
information relating to corporate opportunities, research, financial and sales
data, pricing and trading terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the
identity of key contacts within the customer's organizations or within the
organization of acquisition prospects, or marketing and merchandising
techniques, prospective names, and marks) shall be disclosed to Employer and are
and shall be the sole and exclusive property of Employer. Moreover, all
drawings, memoranda, notes, records, files, correspondence, drawings, manuals,
models, specifications, computer programs, maps and all other writings or
materials of any type embodying any of such information, ideas, concepts,
improvements, discoveries, and inventions are and shall be the sole and
exclusive property of Employer.

         6.2 Employee acknowledges that the business of Employer, Enron, and
their affiliates is highly competitive and that their strategies, methods,
books, records, and documents, their technical information concerning their
products, equipment, services, and processes, procurement procedures and pricing
techniques, the names of and other information (such as credit and financial
data) concerning their customers and business affiliates, all comprise
confidential business information and trade secrets which are valuable, special,
and unique assets which Employer, Enron, or their affiliates use in their
business to obtain a competitive advantage over their competitors. Employee
further acknowledges that protection of such confidential business information
and trade secrets against unauthorized disclosure and use is of critical
importance to 




                                       9

Employer, Enron, and their affiliates in maintaining their competitive position.
Employee hereby agrees that Employee will not, at any time during or after his
or her employment by Employer, make any unauthorized disclosure of any
confidential business information or trade secrets of Employer, Enron, or their
affiliates, or make any use thereof, except in the carrying out of his or her
employment responsibilities hereunder. Enron and its affiliates shall be third
party beneficiaries of Employee's obligations under this Section. As a result of
Employee's employment by Employer, Employee may also from time to time have
access to, or knowledge of, confidential business information or trade secrets
of third parties, such as customers, suppliers, partners, joint venturers, and
the like, of Employer, Enron, and their affiliates. Employee also agrees to
preserve and protect the confidentiality of such third party confidential
information and trade secrets to the same extent, and on the same basis, as
Employer's confidential business information and trade secrets. Employee
acknowledges that money damages would not be sufficient remedy for any breach of
this Article 6 by Employee, and Employer shall be entitled to enforce the
provisions of this Article 6 by terminating any payments then owing to Employee
under this Agreement and/or to specific performance and injunctive relief as
remedies for such breach or any threatened breach. Such remedies shall not be
deemed the exclusive remedies for a breach of this Article 6, but shall be in
addition to all remedies available at law or in equity to Employer, including
the recovery of damages from Employee and his or her agents involved in such
breach.

         6.3 All written materials, records, and other documents made by, or
coming into the possession of, Employee during the period of Employee's
employment by Employer which contain or disclose confidential business
information or trade secrets of Employer, Enron, or their affiliates shall be
and remain the property of Employer, Enron, or their affiliates, as the case may
be. Upon termination of Employee's employment by Employer, for any reason,
Employee promptly shall deliver the same, and all copies thereof, to Employer.

         6.4 If, during Employee's employment by Employer, Employee creates any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures, or the like) relating to Employer's business,
products, or services, whether such work is created solely by Employee or
jointly with others (whether during business hours or otherwise and whether on
Employer's premises or otherwise), Employee shall disclose such work to
Employer. Employer shall be deemed the author of such work if the work is
prepared by Employee in the scope of his or her employment; or, if the work is
not prepared by Employee within the scope of his or her employment but is
specially ordered by Employer as a contribution to a collective work, as a part
of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation, or as an instructional text, then the work
shall be considered to be work made for hire and Employer shall be the author of
the work. If such work is neither prepared by the Employee within the scope of
his or her employment nor a work specially ordered and is deemed to be a work
made for hire, then Employee hereby agrees to assign, and by these presents does
assign, to Employer all of Employee's worldwide right, title, and interest in
and to such work and all rights of copyright therein.

         6.5 Both during the period of Employee's employment by Employer and
thereafter, Employee shall assist Employer and its nominee, at any time, in the
protection of Employer's 




                                       10
<PAGE>   11

worldwide right, title, and interest in and to information, ideas, concepts,
improvements, discoveries, and inventions, and its copyrighted works, including
without limitation, the execution of all formal assignment documents requested
by Employer or its nominee and the execution of all lawful oaths and
applications for applications for patents and registration of copyright in the
United States and foreign countries.

ARTICLE 7:   POST-EMPLOYMENT NON-COMPETITION OBLIGATIONS:

         7.1 As part of the consideration for the compensation and benefits to
be paid to Employee hereunder, in keeping with Employee's duties as a fiduciary
and in order to protect Employer's interests in the confidential information of
Employer and the business relationships developed by Employee with the clients
and potential clients of Employer, and as an additional incentive for Employer
to enter into this Agreement, Employer and Employee agree to the non-competition
provisions of this Article 7. Employee agrees that during the period of
Employee's non-competition obligations hereunder, Employee will not, directly or
indirectly for Employee or for others, in any geographic area or market where
Employer 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 business conducted by
             Employer;

        (ii) render advice or services to, or otherwise assist, any other
person, association, or entity who is engaged, directly or indirectly, in any
business competitive with the business conducted by Employer;

       (iii) induce any employee of Employer or Enron or any of their
affiliates to terminate his or her employment with Employer, Enron, 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 December 31, 2001.

         7.2 Employee understands that the foregoing restrictions may limit his
or her ability to engage in certain businesses anywhere in the world during the
period provided for above, but acknowledges that Employee will receive
sufficiently high remuneration and other benefits (e.g., the right to receive
compensation under Section 3.5 for the remainder of the Term upon Involuntary
Termination) under this Agreement to justify such restriction. Employee
acknowledges that money damages would not be sufficient remedy for any breach of
this Article 7 by Employee, and Employer shall be entitled to enforce the
provisions of this Article 7 by terminating any payments then owing to Employee
under this Agreement and/or to specific performance and injunctive relief as
remedies for such breach or any threatened breach. Such remedies shall not be
deemed the exclusive remedies for a breach of this Article 7, but shall be in
addition to all remedies available at law or in equity to Employer, including,
without limitation, the recovery of damages from Employee and his or her agents
involved in such breach.

         7.3 It is expressly understood and agreed that Employer and Employee
consider the restrictions contained in this Article 7 to be reasonable and
necessary to protect the proprietary information of Employer. Nevertheless, if
any of the aforesaid restrictions are found by a court 




                                       11
<PAGE>   12

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.

ARTICLE 8:   MISCELLANEOUS:

         8.1 For purposes of this Agreement the terms "affiliates" or
"affiliated" means an entity who directly, or indirectly through one or more
intermediaries, controls, is controlled by, or is under common control with
Enron or Employer.

         8.2 Employee shall refrain, both during the employment relationship and
after the employment relationship terminates, from publishing any oral or
written statements about Employer, Enron, any of their respective subsidiaries
or affiliates, or any of such entities' officers, employees, agents or
representatives that are slanderous, libelous, or defamatory; or that disclose
private or confidential information about Employer, Enron, any of their
respective subsidiaries or affiliates, or any of such entities' business
affairs, officers, employees, agents, or representatives; or that constitute an
intrusion into the seclusion or private lives of Employer, Enron, any of their
respective subsidiaries or affiliates, or such entities' officers, employees,
agents, or representatives; or that give rise to unreasonable publicity about
the private lives of Employer, Enron, any of their respective subsidiaries or
affiliates, or any of such entities' officers, employees, agents, or
representatives; or that place Employer, Enron, any of their respective
subsidiaries or affiliates, or any of such entities' or its officers, employees,
agents, or representatives in a false light before the public; or that
constitute a misappropriation of the name or likeness of Employer, Enron, any of
their respective subsidiaries or affiliates, or any of such entities' or its
officers, employees, agents, or representatives. A violation or threatened
violation of this prohibition may be enjoined by the courts. The rights afforded
the Enron entities and affiliates under this provision are in addition to any
and all rights and remedies otherwise afforded by law.

         8.3 For purposes of this Agreement, notices and all other
communications provided for herein shall be in writing and shall be deemed to
have been duly given when personally delivered or when mailed by United States
registered or certified mail, return receipt requested, postage prepaid,

         8.4 This Agreement shall be governed in all respects by the laws of the
State of Texas, excluding any conflict-of-law rule or principle that might refer
the construction of the Agreement to the laws of another State or country.

         8.5 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.

         8.6 If a dispute arises out of or related to this Agreement, other than
a dispute regarding Employee's obligations under Article 6, or Article 7, and if
the dispute cannot be settled through direct discussions, then Employer and
Employee agree to first endeavor to settle the dispute in an amicable manner by
mediation, before having recourse to any other proceeding or forum.

         8.7 Each of Employer and Employee is a citizen of the State of Texas.

Agreement, shall be brought exclusively in the State or federal courts sitting
in Houston, Harris County, Texas. In the event that service of process cannot be
effected upon a party, each party hereby irrevocably appoints the Secretary of
State for the State of Texas as its or her agent for service of process to
receive the summons and other pleadings in connection with any such litigation.

         8.8 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,
association, or entity 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, association, or entity or circumstances other than those
to which they have been held invalid or unenforceable, shall remain in full
force and effect.

         8.9 This Agreement shall be binding upon and inure to the benefit of
Employer and any other person, association, or entity which may hereafter
acquire or succeed to all or substantially all of the business or assets of
Employer by any means whether direct or indirect, by purchase, merger,

hereof are personal and such rights, benefits, and obligations of Employee shall
not be voluntarily or involuntarily assigned, alienated, or transferred, whether

         8.10 There exist other agreements between Employer and Employee
relating to the employment relationship between them, e.g., the agreement with
respect to company policies contained in Employer's Conduct of Business Affairs
booklet and agreements with respect to benefit plans. This Agreement replaces
and merges previous agreements and discussions pertaining to the following
subject matters covered herein: the nature of Employee's employment relationship
with Employer and the term and termination of such relationship. This Agreement
constitutes the entire agreement of the parties with regard to such subject
matters, and contains all of the covenants, promises, representations,
warranties, and agreements between the parties with respect such subject
matters. Each party to this Agreement acknowledges that no representation,
inducement, promise, or agreement, oral or written, has been made by either
party with respect to such subject matters, which is not embodied herein, and

by Employer that is not contained in this Agreement shall be valid or binding.
Any modification of this Agreement will be effective only if it is in writing
and signed by each party whose rights hereunder are affected thereby, provided
that any such modification must be authorized or approved by the Board of
Directors of Employer.

         IN WITNESS WHEREOF, Employer and Employee have duly executed this
Agreement in multiple originals to be effective on the date first stated above.

         NOW, THEREFORE, in consideration thereof and of the mutual covenants
contained herein, the parties agree as follows:

                  1. Effective February 1, 1999, the Employment Agreement is
         assigned by Company to, and assumed by, Enron Corp. and Azurix Corp.,
         respectively. Any reference to the "Company" and/or "Employer" in the
         Employment Agreement shall mean Enron Corp. and Azurix Corp.,
         respectively. Employee consents to such assignment and assumption, and
         releases Company from every obligation under the Employment Agreement.
         Enron Corp. and Azurix Corp., respectively, each assume the obligations
         of Enron Corp. and Azurix Corp., under the Employment Agreement.

                  2. Article 3, Section 3.5 is hereby deleted in its entirety
         and the following language inserted in its entirety:

                         "3.5 Upon an Involuntary Termination of the employment
         relationship by either Employer or Employee prior to the expiration of
         the Term, Employee shall be entitled, in consideration of Employee's
         continuing obligations hereunder after such termination (including,
         without limitation, Employee's non-competition obligations), to
         receive the compensation specified in Section 2.1, as well as unpaid
         Bonuses described on Exhibit "A", as if Employee's employment (which
         shall cease on the date of such Involuntary Termination) had continued

         Employee shall also be entitled to all vested benefits and rights
         under other Enron benefits, incentive, and/or compensation plans to

<PAGE>   17

          on a semi-monthly basis; the unpaid Bonuses described in Exhibit "A"
          will be paid annually and the amounts under the compensation plans
          will be paid in accordance with the terms and provisions of the
          respective compensation plans. Employee shall not be under any duty or
          obligation to seek or accept other employment following Involuntary
          Termination and the amounts due Employee hereunder shall not be
          reduced or suspended if Employee accepts subsequent employment.
          Employee's rights under this Section 3.5 are Employee's sole and
          exclusive rights against Employer, Enron, or their affiliates, and
          Employer's sole and exclusive liability to Employee under this
          Agreement, in contract, tort, or otherwise, for any Involuntary
          Termination of the employment relationship. Employee covenants not to
          sue or lodge any claim, demand or cause of action against Employer for
          any sums for Involuntary Termination other than those sums specified
          in this Section 3.5. If Employee breaches this covenant, Employer
          shall be entitled to recover from Employee all sums expended by
          Employer (including costs and attorneys fees) in connection with such
          suit, claim, demand or cause of action."

                  3. Article 3, Section 3.8 is hereby deleted in its entirety
          and the following language inserted in its entirety:

                        "3.8 Notwithstanding any provision herein to the 
          contrary, upon a termination of Employee's employment under any of the
          circumstances described in Sections 3.6 or 3.7 above, Employee shall
          be entitled to receive a pro-rata annual bonus payment through the
          date of such termination of employment. Further, upon termination of
          Employee's employment under any of the circumstances described in
          Sections 3.5, 3.6, or 3.7, Employee shall become fully vested in
          specific grants and awards made or awarded to Employee under long term
          incentive plans maintained solely by Enron Corp. and its affiliates;
          provided however, any grants and awards made or awarded under the
          Azurix Corp. 1999 Stock Plan shall be excluded and governed by the
          terms and provisions of the respective grants and awards under the
          Azurix Corp. 1999 Stock Plan."

                  4. Exhibit "A" to the Employment Agreement is hereby deleted
          in its entirety and the attached Exhibit "A" is inserted in its

and effect and without any change or modification, except as provided herein.

                         EXECUTIVE EMPLOYMENT AGREEMENT

     This Employment Agreement ("Agreement"), including the attached Exhibit
"A," is entered into between AZURIX CORP., a Delaware corporation ("Employer")
and subsidiary of ENRON CORP., an Oregon corporation, having offices at 1400
Smith Street, Houston, Texas 77002 ("Enron"), and RODNEY L. GRAY, an individual
currently residing at 4146 Marquette, Houston, Texas 77005 ("Employee"), to be
effective as of February 16, 1999 (the "Effective Date").

                                   WITNESSETH:

     WHEREAS, Employer is desirous of employing Employee pursuant to the terms
and conditions and for the consideration set forth in this Agreement, and
Employee is desirous of entering the employ of Employer pursuant to such terms
and conditions and for such consideration.

     NOW, THEREFORE, for and in consideration of the mutual promises, covenants,
and obligations contained herein, Employer and Employee agree as follows:

ARTICLE 1: EMPLOYMENT AND DUTIES:

     1.1 Employer agrees to employ Employee, and Employee agrees to be employed
by Employer, beginning as of the Effective Date and continuing until the date
set forth on Exhibit "A" (the "Term"), subject to the terms and conditions of
this Agreement.

     1.2 Employee initially shall be employed in the position set forth on
Exhibit A. Employer may subsequently assign Employee to a different position or
modify Employee's duties and responsibilities, provided that no such assignment
or modification shall result in a substantial reduction of Employee's duties and
responsibilities. Moreover, Employer may assign this Agreement and Employee's
employment to any affiliates of Employer. Employee agrees to serve in the
assigned position and to perform diligently and to the best of Employee's
abilities the duties and services appertaining to such position as determined by
Employer, as well as such additional or different duties and services
appropriate to such position which Employee from time to time may be reasonably
directed to perform by Employer. Employee shall at all times comply with and be
subject to such policies and procedures as Employer may establish from time to
time.

     1.3 Employee shall, during the period of Employee's employment by Employer,
devote Employee's full business time, energy, and best efforts to the business
and affairs of Employer. Employee may not engage, directly or indirectly, in any
other business, investment, or activity that interferes with Employee's
performance of Employee's duties hereunder, is contrary to the interests of
Employer or Enron, or requires any significant portion of Employee's business
time.

     1.4 In connection with Employee's employment by Employer, Employer shall
endeavor to provide Employee access to such confidential information pertaining
to the business and services of Employer as is appropriate for Employee's
employment responsibilities. Employer also shall endeavor to provide to Employee
the opportunity to develop business relationships with those of




                                       1
<PAGE>   2




Employer's clients and potential clients that are appropriate for Employee's
employment responsibilities.

     1.5 Employee acknowledges and agrees that, at all times during the
employment relationship Employee owes fiduciary duties to Employer, including
but not limited to the fiduciary duties of the highest loyalty, fidelity and
allegiance to act at all times in the best interests of the Employer, to make
full disclosure to Employer of all information that pertains to Employer's
business and interests, to do no act which would injure Employer's business, its
interests, or its reputation, and to refrain from using for Employee's own
benefit or for the benefit of others any information or opportunities pertaining
to Employer's business or interests that are entrusted to Employee or that he
learned while employed by Employer. Employee acknowledges and agrees that upon
termination of the employment relationship, Employee shall continue to refrain
from using for his own benefit or the benefit of others any information or
opportunities pertaining to Employer's business or interests that were entrusted
to Employee during the employment relationship or that he learned while employed
by Employer. Employee agrees that while employed by Employer and thereafter he
shall not knowingly take any action which interferes with the internal
relationships between Employer and its employees or representatives or
interferes with the external relationships between Employer and third parties.

     1.6 It is agreed that any direct or indirect interest in, connection with,
or benefit from any outside activities, particularly commercial activities,
which interest might in any way adversely affect Employer or any of its
affiliates, involves a possible conflict of interest. In keeping with Employee's
fiduciary duties to Employer, Employee agrees that during the employment
relationship Employee shall not knowingly become involved in a conflict of
interest with Employer or its affiliates, or upon discovery thereof, allow such
a conflict to continue. Moreover, Employee agrees that Employee shall disclose
to Employer's President any facts which might involve such a conflict of
interest that has not been approved by Employer's President. Employer and
Employee recognize that it is impossible to provide an exhaustive list of
actions or interests which constitute a "conflict of interest." Moreover,
Employer and Employee recognize there are many borderline situations. In some
instances, full disclosure of facts by the Employee to Employer's President may
be all that is necessary to enable Employer or its affiliates to protect its
interests. In others, if no improper motivation appears to exist and the
interests of Employer or its affiliates have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for
Employer to terminate the employment relationship. Employer and Employee agree
that Employer's determination as to whether a conflict of interest exists shall
be conclusive. Employer reserves the right to take such action as, in its
judgment, will end the conflict.

     1.7 Employee understands and acknowledges that the terms and conditions of
this Agreement constitute confidential information. Employee shall keep
confidential the terms of this Agreement and shall not disclose this
confidential information to anyone other than Employee's attorneys, tax
advisors, or as required by law. Employee acknowledges and understands that
disclosure of the terms of this Agreement constitutes a material breach of this
Agreement and could subject Employee to disciplinary action, including without
limitation, termination of employment.

ARTICLE 2: COMPENSATION AND BENEFITS:

     2.1 Employee's monthly base salary during the Term shall be not less than
the amount set forth under the heading "Monthly Base Salary" on Exhibit A,
subject to increase at the sole discretion of the Employer, which shall be paid
in semimonthly installments in accordance with Employer's standard payroll
practice. Any calculation to be made under this Agreement with respect to
Employee's Monthly Base Salary shall be made using the then current Monthly Base
Salary in effect at the time of the event for which such calculation is made.

     2.2 While employed by Employer (both during the Term and thereafter),
Employee shall be allowed to participate, on the same basis generally as other
employees of Employer, in all general employee benefit plans and programs,
including improvements or modifications of the same, which on the effective date
or thereafter are made available by Employer to all or substantially all of
Employer's employees. Such benefits, plans, and programs may include, without
limitation, medical, health, and dental care, life insurance, disability
protection, and pension plans. Nothing in this Agreement is to be construed or
interpreted to provide greater rights, participation, coverage, or benefits
under such benefit plans or programs than provided to similarly situated
employees pursuant to the terms and conditions of such benefit plans and
programs.

     2.3 Employer shall not by reason of this Article 2 be obligated to
institute, maintain, or refrain from changing, amending, or discontinuing, any
such incentive compensation or employee benefit program or plan, so long as such
actions are similarly applicable to covered employees generally. Moreover,
unless specifically provided for in a written plan document adopted by the Board
of Directors of either Employer or Enron, none of the benefits or arrangements
described in this Article 2 shall be secured or funded in any way, and each
shall instead constitute an unfunded and unsecured promise to pay money in the
future exclusively from the general assets of Employer.

     2.4 Employer may withhold from any compensation, benefits, or amounts
payable under this Agreement all federal, state, city, or other taxes as may be
required pursuant to any law or governmental regulation or ruling.

ARTICLE 3: TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF SUCH
TERMINATION:

     3.1. Notwithstanding any other provisions of this Agreement, Employer shall
have the right to terminate Employee's employment under this Agreement at any
time prior to the expiration of the Term for any of the following reasons:

     (i)  For "cause" upon the determination by the Employer's Board of
          Directors or Enron's management committee (or, if there is no Enron
          management committee, the highest applicable level of Enron
          management) that "cause" exist's for the termination of the employment
          relationship. As used in this Section 3. 1 (i), the term "cause" shall
          mean [a] Employee's gross negligence or willful misconduct in the
          performance of the duties and services required of Employee pursuant
          to this Agreement; [b] Employee has been convicted of a felony; [c]
          Employee has willfully refused without proper legal reason to perform
          the duties and responsibilities required of Employee under this
          Agreement which remains uncorrected for thirty (30) days following
          written notice to Employee by Employer of such breach; [d] Employee's
          involvement in a 


                                       3
<PAGE>   4



          conflict of interest as referenced in Section 1.6 for which Employer
          makes a determination to terminate the employment of Employee which
          remains uncorrected for thirty (30) days following written notice to
          Employee by Employer of such breach; [e] Employee has willfully
          engaged in conduct that Employee knows or should know is materially
          injurious to Employer, Enron, or any of their respective subsidiaries;
          [f] Employee's material breach of any material provision of this
          Agreement or corporate code or policy which remains uncorrected for
          thirty (30) days following written notice to Employee by Employer of
          such breach; or [g] Employee violates the Foreign Corrupt Practices
          Act or other applicable United States law as proscribed by Section
          5.1. It is expressly acknowledged and agreed that the decision as to
          whether "cause" exists for termination of the employment relationship
          by Employer is delegated to the Employer's management committee (or,
          if there is no management committee, the highest applicable level of
          Employer's management) for determination. If Employee disagrees with
          the decision reached by Employee's management committee (or, if there
          is no management committee, the highest applicable level of Employer's
          management), the dispute will be limited to whether Employer's
          management committee (or, if there is no Enron management committee,
          the highest applicable level of Employer's management) reached its
          decision in good faith;

     (ii) for any other reason whatsoever, with or without cause, in the sole
          discretion of the management committee (or, if there is no management
          committee, the highest applicable level of management) of Employer;

    (iii) upon Employee's death; or

     (iv) upon Employee's becoming disabled so as to entitle Employee to
          benefits under Enron's long-term disability plan or, if Employee is
          not eligible to participate in such plan, then Employee is permanently
          and totally unable to perform Employee's duties for Employer as a
          result of any medically determinable physical or mental impairment as
          supported by a written medical opinion to the foregoing effect by a
          physician selected by Employer.

The termination of Employee's employment by Employer prior to the expiration of
the Term shall constitute a "Termination for Cause" if made pursuant to Section
3.1(i); the effect of such termination is specified in Section 3.4. The
termination of Employee's employment by Employer prior to the expiration of the
Term shall constitute an "Involuntary Termination" if made pursuant to Section
3.1(ii); the effect of such termination is specified in Section 3.5. The effect
of the employment relationship being terminated pursuant to Section 3.1(iii)
as a result of Employee's death is specified in Section 3.6. The effect of the
employment relationship being terminated pursuant to Section 3.1(iv) as a result
of the Employee becoming incapacitated is specified in Section 3.7.

     3.2 Notwithstanding any other provisions of this Agreement except Section
8.6, Employee shall have the right to terminate the employment relationship
under this Agreement at any time prior to the expiration of the Term of
employment for any of the following reasons: 



                                       4
<PAGE>   5



     (i)  a material breach by Employer of any material provision of this
          Agreement which remains uncorrected for 30 days following written
          notice of such breach by Employee to Employer; or 

     (ii) for any other reason whatsoever, in the sole discretion of Employee.

The termination of Employee's employment by Employee prior to the expiration of
the Term shall constitute an "Involuntary Termination" if made pursuant to
Section 3.2(i); the effect of such termination is specified in Section 3.5. The
termination of Employee's employment by Employee prior to the expiration of the
Term shall constitute a "Voluntary Termination" if made pursuant to Section
3.2(ii); the effect of such termination is specified in Section 3.3.

     3.3 Upon a "Voluntary Termination" of the employment relationship by
Employee prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible
shall cease and terminate as of the date of termination. Employee shall be
entitled to pro rata salary through the date of such termination, but Employee
shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

     3.4 If Employee's employment hereunder shall be terminated by Employer for
Cause prior to expiration of the Term, all future compensation to which Employee
is entitled and all future benefits for which Employee is eligible shall cease
and terminate as of the date of termination. Employee shall be entitled to pro
rata salary through the date of such termination, but Employee shall not be
entitled to any individual bonuses or individual incentive compensation not yet
paid at the date of such termination.

     3.5 Upon an Involuntary Termination of the employment relationship by
either Employer or Employee prior to the expiration of the Term, Employee shall
be entitled, in consideration of Employee's continuing obligations hereunder
after such termination (including, without limitation, Employee's
non-competition obligations), to receive the compensation specified in Section
2.1, as well as unpaid Bonuses described on Exhibit "A", as if Employee's
employment (which shall cease on the date of such Involuntary Termination) had
continued for the full Term of this Agreement. Upon an Involuntary Termination,
Employee shall also be entitled to all vested benefits and rights under other
Enron benefits, incentive, and/or compensation plans to which Employee may be
entitled through his termination and pursuant to plan documents and all other
benefits that Employee may be entitled to under any other compensation plans. In
the event of Involuntary Termination, the compensation specified in Section 2.1
that will be paid to Employee will be paid on a semi-monthly basis; the unpaid
Bonuses described in Exhibit "A" will be paid annually and the amounts under the
compensation plans will be paid in accordance with the terms and provisions of
the respective compensation plans. Employee shall not be under any duty or
obligation to seek or accept other employment following Involuntary Termination
and the amounts due Employee hereunder shall not be reduced or suspended if
Employee accepts subsequent employment. Employee's rights under this Section 3.5
are Employee's sole and exclusive rights against Employer, Enron, or their
affiliates, and Employer's sole and exclusive liability to Employee under this
Agreement, in contract, tort, or otherwise, for any Involuntary Termination of
the employment relationship. Employee covenants not to sue or lodge any claim, 
demand or cause of



                                       5
<PAGE>   6



action against Employer for any sums for Involuntary Termination other than
those sums specified in this Section 3.5. If Employee breaches this covenant,
Employer shall be entitled to recover from Employee all sums expended by
Employer (including costs and attorneys fees) in connection with such suit,
claim, demand or cause of action.

     3.6 Upon termination of the employment relationship as a result of
Employee's death, Employee's heirs, administrators, or legatees shall be
entitled to Employee's pro rata salary through the date of such termination, but
Employee's heirs, administrators, or legatees shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

     3.7 Upon termination of the employment relationship as a result of
Employee's incapacity, Employee shall be entitled to his or her pro rata salary
through the date of such termination, but Employee shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

     3.8 In all cases, the compensation and benefits payable to Employee under
this Agreement upon termination of the employment relationship shall be offset
against any amounts to which Employee may otherwise be entitled under any and
all severance plans, and policies of Employer, Enron, or its affiliates.

     3.9 Termination of the employment relationship does not terminate those
obligations imposed by this Agreement which are continuing obligations,
including, without limitation, Employee's obligations under Articles 6 and 7.

ARTICLE 4: CONTINUATION OF EMPLOYMENT BEYOND TERM; TERMINATION AND EFFECTS OF
           TERMINATION:

     4.1 Should Employee remain employed by Employer beyond the expiration of
the Term specified on Exhibit "A," such employment shall convert to a
month-to-month relationship terminable at any time by either Employer or
Employee for any reason whatsoever, with or without cause. Upon such termination
of the employment relationship by either Employer or Employee for any reason
whatsoever, all future compensation to which Employee is entitled and all
future benefits for which Employee is eligible shall cease and terminate.
Employee shall be entitled to pro rata salary through the date of such
termination, but Employee shall not be entitled to any individual bonuses or
individual incentive compensation not yet paid at the date of such termination.

ARTICLE 5: UNITED STATES FOREIGN CORRUPT PRACTICES ACT AND OTHER LAWS:

     5.1. Employee shall at all times comply with United States laws applicable
to Employee's actions on behalf of Employer, including specifically, without
limitation, the United States Foreign Corrupt Practices Act, generally codified
in 15 USC 78 (FCPA), as the FCPA may hereafter be amended, and/or its successor
statutes. If Employee pleads guilty to or nolo contendere or admits civil or
criminal liability under the FCPA or other applicable United States law, or if a
court finds that Employee has personal civil or criminal liability under the
FCPA or other applicable United



                                       6

States law, or if a court finds that Employee committed an action resulting in
any Enron entity having civil or criminal liability or responsibility under the
FCPA or other applicable United States law with knowledge of the activities
giving rise to such liability or knowledge of facts from which Employee should
have reasonably inferred the activities giving rise to liability had occurred or
were likely to occur, such action or finding shall constitute "cause" for
termination under this Agreement unless Employer's management committee (or, if
there is no management committee, the highest applicable level of Employer's
management) determines that the actions found to be in violation of the FCPA or
other applicable United States law were taken in good faith and in compliance
with all applicable policies of Employer and Enron.

ARTICLE 6: OWNERSHIP AND PROTECTION OF INFORMATION; COPYRIGHTS:

     6.1 All information, ideas, concepts, improvements, discoveries, and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by Employee, individually or in conjunction with others, during
Employee's employment by Employer (whether during business hours or otherwise
and whether on Employer's premises or otherwise) which relate to Employer's
business, products or services (including, without limitation, all such
information relating to corporate opportunities, research, financial and sales
data, pricing and trading terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the
identity of key contacts within the customer's organizations or within the
organization of acquisition prospects, or marketing and merchandising
techniques, prospective names, and marks) shall be disclosed to Employer and are
and shall be the sole and exclusive property of Employer. Moreover, all
drawings, memoranda, notes, records, files, correspondence, drawings, manuals,
models, specifications, computer programs, maps and all other writings or
materials of any type embodying any of such information, ideas, concepts,
improvements, discoveries, and inventions are and shall be the sole and
exclusive property of Employer.

     6.2 Employee acknowledges that the business of Employer, Enron, and their
affiliates is highly competitive and that their strategies, methods, books,
records, and documents, their technical information concerning their products,
equipment, services, and processes, procurement procedures and pricing
techniques, the names of and other information (such as credit and financial
data) concerning their customers and business affiliates, all comprise
confidential business information and trade secrets which are valuable, special,
and unique assets which Employer, Enron, or their affiliates use in their
business to obtain a competitive advantage over their competitors. Employee
further acknowledges that protection of such confidential business information
and trade secrets against unauthorized disclosure and use is of critical
importance to Employer, Enron, and their affiliates in maintaining their
competitive position. Employee hereby agrees that Employee will not, at any time
during or after his or her employment by Employer, make any unauthorized
disclosure of any confidential business information or trade secrets of
Employer, Enron, or their affiliates, or make any use thereof, except in the
carrying out of his or her employment responsibilities hereunder. Enron and its
affiliates shall be third party beneficiaries of Employee's obligations under
this Section. As a result of Employee's employment by Employer, Employee may
also from time to time have access to, or knowledge of, confidential business
information or trade secrets of third parties, such as customers, suppliers,
partners, joint venturers, and the like, of Employer, Enron, and their
affiliates. Employee also agrees to preserve and protect the confidentiality of
such third party confidential information and trade secrets to the same extent,
and on the same basis, as Employer's 


                                       7
<PAGE>   8



confidential business information and trade secrets. Employee acknowledges that
money damages would not be sufficient remedy for any breach of this Article 6 by
Employee, and Employer shall be entitled to enforce the provisions of this
Article 6 by terminating any payments then owing to Employee under this
Agreement and/or to specific performance and injunctive relief as remedies for
such breach or any threatened breach. Such remedies shall not be deemed the
exclusive remedies for a breach of this Article 6, but shall be in addition to
all remedies available at law or in equity to Employer, including the recovery
of damages from Employee and his or her agents involved in such breach.

     6.3 All written materials, records, and other documents made by, or coming
into the possession of, Employee during the period of Employee's employment by
Employer which contain or disclose confidential business information or trade
secrets of Employer, Enron, or their affiliates shall be and remain the property
of Employer, Enron, or their affiliates, as the case may be. Upon termination of
Employee's employment by Employer, for any reason, Employee promptly shall
deliver the same, and all copies thereof, to Employer.

     6.4 If, during Employee's employment by Employer, Employee creates any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures, or the like) relating to Employer's business
products, or services, whether such work is created solely by Employee or
jointly with others (whether during business hours or otherwise and whether on
Employer's premises or otherwise), Employee shall disclose such work to
Employer. Employer shall be deemed the author of such work if the work is
prepared by Employee in the scope of his or her employment; or, if the work is
not prepared by Employee within the scope of his or her employment but is
specially ordered by Employer as a contribution to a collective work, as a part
of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation, or as an instructional text, then the work
shall be considered to be work made for hire and Employer shall be the author of
the work. If such work is neither prepared by the Employee within the scope of
his or her employment nor a work specially ordered and is deemed to be a work
made for hire, then Employee hereby agrees to assign, and by these presents does
assign, to Employer all of Employee's worldwide right, title, and interest in
and to such work and all rights of copyright therein.

     6.5 Both during the period of Employee's employment by Employer and
thereafter, Employee shall assist Employer and its nominee, at any time, in the
protection of Employer's worldwide right, title, and interest in and to
information, ideas, concepts, improvements, discoveries, and inventions, and its
copyrighted works, including without limitation, the execution of all formal
assignment documents requested by Employer or its nominee and the execution of
all lawful oaths and applications for applications for patents and registration
of copyright in the United States and foreign countries.

ARTICLE 7: POST-EMPLOYMENT NON-COMPETITION OBLIGATIONS:

     7.1 As part of the consideration for the compensation and benefits to be
paid to Employee hereunder, in keeping with Employee's duties as a fiduciary and
in order to protect Employer's interests in the confidential information of
Employer and the business relationships


                                       8
<PAGE>   9



developed by Employee with the clients and potential clients of Employer, and as
an additional incentive for Employer to enter into this Agreement, Employer and
Employee agree to the noncompetition provisions of this Article 7. Employee
agrees that during the period of Employee's noncompetition obligations
hereunder, Employee will not, directly or indirectly for Employee or for others,
in any geographic area or market where Employer or Enron or any of their
affiliated companies related to the water business, 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
Employer;

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

     (iii) induce any employee of Employer or Enron or any of their affiliates
to terminate his or her employment with Employer, Enron, 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 expiration of the Term of
this Agreement.

     7.2 Employee understands that the foregoing restrictions may limit his or
her ability to engage in certain businesses anywhere in the world during the
period provided for above, but acknowledges that Employee will receive
sufficiently high remuneration and other benefits (e.g., the right to receive
compensation under Section 3.5 for the remainder of the Term upon Involuntary
Termination) under this Agreement to justify such restriction. Employee
acknowledges that money damages would not be sufficient remedy for any breach of
this Article 7 by Employee, and Employer shall be entitled to enforce the
provisions of this Article 7 by terminating any payments then owing to Employee
under this Agreement and/or to specific performance and injunctive relief as
remedies for such breach or any threatened breach. Such remedies shall not be
deemed the exclusive remedies for a breach of this Article 7, but shall be in
addition to all remedies available at law or in equity to Employer, including,
without limitation, the recovery of damages from Employee and his or her agents
involved in such breach.

     7.3 It is expressly understood and agreed that Employer and Employee
consider the restrictions contained in this Article 7 to be reasonable and
necessary to protect the proprietary information of Employer. 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.

ARTICLE 8. MISCELLANEOUS:

     8.1 For purposes of this Agreement the terms "affiliates" or "affiliated"
means an entity who directly, or indirectly through one or more intermediaries,

after the employment relationship terminates, from publishing any oral or
written statements about Employer, Enron, any of their respective subsidiaries

representatives that are slanderous, libelous, or defamatory; or that disclose
private or confidential information about Employer, Enron, any of their
respective subsidiaries or affiliates, or any of such entities' business
affairs, officers, employees, agents, or representatives; or that constitute an
intrusion into the seclusion or private lives of Employer, Enron, any of their
respective subsidiaries or affiliates, or such entities' officers, employees,
agents, or representatives; or that give rise to unreasonable publicity about
the private lives of Employer, Enron, any of their respective subsidiaries or
affiliates, or any of such entities' officers, employees, agents, or
representatives; or that place Employer, Enron, any of their respective
subsidiaries or affiliates, or any of such entities' or its officers, employees,
agents, or representatives in a false light before the public; or that
constitute a misappropriation of the name or likeness of Employer, Enron, any of
their respective subsidiaries or affiliates, or any of such entities' or its
officers, employees, agents, or representatives. A violation or threatened
violation of this prohibition may be enjoined by the courts. The rights afforded
the Enron entities and affiliates under this provision are in addition to any
and all rights and remedies otherwise afforded by law.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Employment Agreement ("Agreement"), including the attached Exhibit
"A," is entered into between ENRON CAPITAL & TRADE RESOURCES CORP., a Delaware
corporation and subsidiary of Enron Corp. ("Enron"), having offices at 1400
Smith Street, Houston, Texas 77002 ("Employer"), and AMANDA K. MARTIN, an
individual currently residing in Houston, Texas ("Employee"), to be effective as
of January 1, 1998 (the "Effective Date").

                                   WITNESSETH:

         WHEREAS, Employer is desirous of employing Employee pursuant to the
terms and conditions and for the consideration set forth in this Agreement, and
Employee is desirous of entering the employ of Employer pursuant to such terms
and conditions and for such consideration.

         NOW, THEREFORE, for and in consideration of the mutual promises,
covenants, and obligations contained herein, Employer and Employee agree as
follows:

ARTICLE 1:  EMPLOYMENT AND DUTIES:

         1.1 Employer agrees to employ Employee, and Employee agrees to be
employed by Employer, beginning as of the Effective Date and continuing until
the date set forth on Exhibit "A" (the "Term"), subject to the terms and
conditions of this Agreement.

         1.2 Employee initially shall be employed in the position set forth on
Exhibit A. Employer may subsequently assign Employee to a different position
with duties, responsibilities, and reporting relationships that are reasonably
equivalent to the position described on Exhibit "A." Moreover, Employer may
assign this Agreement and Employee's employment to Enron or any affiliates of
Enron; provided, however, that Employer will not transfer Employee to a position
outside of Houston, Texas without Employee's consent. Employee agrees to serve
in the assigned position and to perform diligently and to the best of Employee's
abilities the duties and services appertaining to such position as determined by
Employer, as well as such additional or different duties and services
appropriate to such position which Employee from time to time may be reasonably
directed to perform by Employer. Employee shall at all times comply with and be
subject to such policies and procedures as Employer may establish from time to
time.

         1.3 Employee shall, during the period of Employee's employment by
Employer, devote Employee's full business time, energy, and best efforts to the
business and affairs of Employer. Employee may not engage, directly or
indirectly, in any other business, investment, or activity that interferes with
Employee's performance of Employee's duties hereunder, is contrary to the
interests of Employer or Enron, or requires any significant portion of
Employee's business time. Nothing in this paragraph 1.3 should prohibit Employee
from serving in positions or on Boards that benefit Employer within the energy
industry. Nor is Employee prohibited from providing service and/or serving as a
Board member for non-profit and/or charitable organizations.

responsibilities. Employer also shall provide to Employee the opportunity to
develop business relationships with those of Employer's clients and potential

but not limited to the fiduciary duties of the highest loyalty, fidelity and
allegiance to act at all times in the best interests of the Employer, to make
full disclosure to Employer of all information that pertains to Employer's
business and interests, to do no act which would injure Employer's business, its
interests, or its reputation, and to refrain from using for Employee's own
benefit or for the benefit of others any information or opportunities pertaining
to Employer's business or interests that are entrusted to Employee or that she
learned while employed by Employer. Employee acknowledges and agrees that upon
termination of the employment relationship, Employee shall continue to refrain
from using for her own benefit or the benefit of others any information or
opportunities pertaining to Employer's business or interests that were entrusted
to Employee during the employment relationship or that she learned while
employed by Employer. Employee agrees that while employed by Employer and
thereafter she shall not knowingly take any action which interferes with the
internal relationships between Employer and its employees or representatives or
interferes with the external relationships between Employer and third parties.

         1.6 It is agreed that any direct or indirect interest in, connection
with, or benefit from any outside activities, particularly commercial
activities, which interest might in any way adversely affect Employer or any of
its affiliates, involves a possible conflict of interest. In keeping with
Employee's fiduciary duties to Employer, Employee agrees that during the
employment relationship Employee shall not knowingly become involved in a
conflict of interest with Employer or its affiliates, or upon discovery thereof,
allow such a conflict to continue. Moreover, Employee agrees that Employee shall
disclose to Employer's President any facts which might involve such a conflict
of interest that has not been approved by Employer's President. Employer and
Employee recognize that it is impossible to provide an exhaustive list of
actions or interests which constitute a "conflict of interest." Moreover,
Employer and Employee recognize there are many borderline situations. In some
instances, full disclosure of facts by the Employee to Employer's President may
be all that is necessary to enable Employer or its affiliates to protect its
interests. In others, if no improper motivation appears to exist and the
interests of Employer or its affiliates have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for
Employer to terminate the employment relationship. Employer and Employee agree
that Employer's determination as to whether a conflict of interest exists shall
be conclusive. Employer reserves the right to take such action as, in its
judgment, will end the conflict.

         1.7 Employee may be asked from time to time by Employer or Enron to
serve as a director, officer, or employee of an affiliate or joint venture of
Enron. Employer and Employee acknowledge that from time to time the best
interests of such affiliate or joint venture may 



                                      -2-
<PAGE>   3

arguably diverge from the best interests of Employer and Enron and thus agree
that, notwithstanding any provision of this Agreement to the contrary,
Employee's proper discharge of her duties as a director, officer, or employee,
as applicable, of such affiliate or joint venture shall not, in and of itself,
constitute a breach of any provision of this Agreement or a cause for
termination under Section 3.1(a).

         1.8 Employee acknowledges that the terms and conditions of this
Agreement constitute confidential information. Employee shall not disclose this
confidential information to anyone other than Employee's attorneys, tax
advisors, or as required by law. Employee acknowledges and understands that
disclosure of the terms of this Agreement constitutes a material breach of this
Agreement and could subject Employee to disciplinary action, including without
limitation, termination of employment.

ARTICLE 2:  COMPENSATION AND BENEFITS:

         2.1 Employee's monthly base salary during the Term shall be not less
than the amount set forth under the heading "Monthly Base Salary" on Exhibit A,
subject to increase at the sole discretion of the Employer, which shall be paid
in semimonthly installments in accordance with Employer's standard payroll
practice. On an annual basis, Employer will review Employee's monthly base
salary for purposes of determining the amount of any increase and eligibility
for bonuses or participation in any compensation plan. The annual review and
subsequent compensation and bonus decision will be based on Employee's
performance and comparisons to salaries and bonuses of other similarly-situated
employees of Employer performing in a reasonably equivalent capacity. Any
calculation to be made under this Agreement with respect to Employee's Monthly
Base Salary shall be made using the then current Monthly Base Salary in effect
at the time of the event for which such calculation is made.

         2.2 While employed by Employer (both during the Term and thereafter),
Employee shall be allowed to participate, on the same basis generally as other
employees of Employer, in all general employee benefit plans and programs,
including improvements or modifications of the same, which on the effective date
or thereafter are made available by Employer to all or substantially all of
Employer's employees. Such benefits, plans, and programs may include, without
limitation, medical, health, and dental care, life insurance, disability
protection, and pension plans. Nothing in this Agreement is to be construed or
interpreted to provide greater rights, participation, coverage, or benefits
under such benefit plans or programs than provided to similarly situated
employees pursuant to the terms and conditions of such benefit plans and
programs.

         2.3 Employer shall not by reason of this Article 2 be obligated to
institute, maintain, or refrain from changing, amending, or discontinuing, any
such incentive compensation or employee benefit program or plan, so long as such
actions are similarly applicable to covered employees generally. Moreover,
unless specifically provided for in a written plan document adopted by the Board
of Directors of either Employer or Enron, none of the benefits or arrangements
described in this Article 2 shall be secured or funded in any way, and each
shall



                                      -3-
<PAGE>   4

instead constitute an unfunded and unsecured promise to pay money in the future
exclusively from the general assets of Employer.

         2.4 Employer may withhold from any compensation, benefits, or amounts
payable under this Agreement all federal, state, city, or other taxes as may be
required pursuant to any law or governmental regulation or ruling.

ARTICLE 3: TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF SUCH
           TERMINATION:

         3.1. Notwithstanding any other provisions of this Agreement, Employer
shall have the right to terminate Employee's employment under this Agreement at
any time prior to the expiration of the Term for any of the following reasons:

                  a. For "cause" upon the good faith determination by the
         Employer's management committee (or, if there is no management
         committee, the highest applicable level of management) of Employer that
         "cause" exists for the termination of the employment relationship. As
         used in this Section 3.1.a, the term "cause" shall mean (i) Employee's
         gross negligence or willful misconduct in the performance of the duties
         and services required of Employee pursuant to this Agreement; (ii)
         Employee's final conviction of a felony; (iii) Employee's involvement
         in a conflict of interest as referenced in Sections 1.5-1.6 for which
         Employer makes a determination to terminate the employment of Employee
         which remains uncorrected for thirty (30) days following written notice
         to Employee by Employer; or (iv) Employee's material breach of any
         material provision of this Agreement which remains uncorrected for
         thirty (30) days following written notice to Employee by Employer of
         such breach. It is expressly acknowledged and agreed that the decision
         as to whether "cause" exists for termination of the employment
         relationship by Employer is delegated to the management committee (or,
         if there is no management committee, the highest applicable level of
         management) of Employer for determination;

                  b. for any other reason whatsoever, including termination
         without cause, in the sole discretion of the management committee (or,
         if there is no management committee, the highest applicable level of
         management) of Employer;

                  c. upon Employee's death; or

                  d. upon Employee's becoming disabled so as to entitle Employee
         to benefits under Enron's long-term disability plan or, if Employee is
         not eligible to participate in such plan, then Employee is permanently
         and totally unable to perform Employee's duties for Employer as a
         result of any medically determinable physical or mental impairment as
         supported by a written medical opinion to the foregoing effect by a
         physician selected by Employer.

The termination of Employee's employment by Employer prior to the expiration of
the Term shall constitute a "Termination for Cause" if made pursuant to Section
3.1.a; the effect of such



                                      -4-
<PAGE>   5

termination is specified in Section 3.4. The termination of Employee's
employment by Employer prior to the expiration of the Term shall constitute an
"Involuntary Termination" if made pursuant to Section 3.1.b; the effect of such
termination is specified in Section 3.5. The effect of the employment
relationship being terminated pursuant to Section 3.1.c as a result of
Employee's death is specified in Section 3.6. The effect of the employment
relationship being terminated pursuant to Section 3.1.d as a result of the
Employee becoming incapacitated is specified in Section 3.7.

         3.2 Notwithstanding any other provisions of this Agreement except
Section 7.6, Employee shall have the right to terminate the employment
relationship under this Agreement at any time prior to the expiration of the
Term of employment for any of the following reasons:

                  a. a material breach by Employer of any material provision of
         this Agreement which remains uncorrected for 30 days following written
         notice of such breach by Employee to Employer; or

                  b. for any other reason whatsoever, in the sole discretion of
         Employee.

The termination of Employee's employment by Employee prior to the expiration of
the Term shall constitute an "Involuntary Termination" if made pursuant to
Section 3.2.a; the effect of such termination is specified in Section 3.5. The
termination of Employee's employment by Employee prior to the expiration of the
Term shall constitute a "Voluntary Termination" if made pursuant to Section
3.2.b; the effect of such termination is specified in Section 3.3.

         3.3 Upon a "Voluntary Termination" of the employment relationship by
Employee prior to expiration of the Term, all future compensation described on
Exhibit "A" to which Employee is entitled and all future benefits for which
Employee is eligible, with the exception of vested benefits and/or rights under
other Enron benefit, incentive, and/or compensation plans, as well as any and
all statutory rights and benefits, shall cease and terminate as of the date of
termination. Employee shall be entitled to pro rata salary through the date of
such termination, but Employee shall not be entitled to any individual bonuses
or individual incentive compensation not yet paid at the date of such
termination.

         3.4 If Employee's employment hereunder shall be terminated by Employer
for Cause prior to expiration of the Term, all future compensation described on
Exhibit "A" to which Employee is entitled and all future benefits for which
Employee is eligible, with the exception of vested benefits and/or rights under
other Enron benefit incentive, and/or compensation plans, as well as any and all
statutory rights and benefits, shall cease and terminate as of the date of
termination. Employee shall be entitled to pro rata salary through the date of
such termination, but Employee shall not be entitled to any individual bonuses
or individual incentive compensation not yet paid at the date of such
termination.

         3.5 Upon an Involuntary Termination of the employment relationship by
either Employer or Employee prior to expiration of the Term, Employee shall be
entitled, in consideration of Employee's continuing obligations hereunder after
such termination (including, without limitation, Employee's non-competition
obligations), to receive the compensation



                                      -5-
<PAGE>   6

specified in Section 2.1, as well as the unpaid Retention Bonuses described on
Exhibit "A," as if Employee's employment (which shall cease on the date of such
Involuntary Termination) had continued for the full Term of this Agreement. Upon
an Involuntary Termination, Employee also will be entitled to all vested
benefits and rights under other Enron benefits, incentive, and/or compensation
plans to which Employee may be entitled through her termination and pursuant to
plan documents. In the event of Involuntary Termination, the compensation
specified in Section 2.1 that will be paid to Employee will be paid on a
semi-monthly basis; the unpaid Retention Bonuses described in Exhibit A will be
paid on the dates noted on Exhibit A. Employee shall not be under any duty or
obligation to seek or accept other employment following Involuntary Termination
and the amounts due Employee hereunder shall not be reduced or suspended if
Employee accepts subsequent employment. Employee's rights under this Section 3.5
are Employee's sole and exclusive rights against Employer, Enron, or their
affiliates, and Employer's sole and exclusive liability to Employee under this
Agreement, in contract, tort, or otherwise, for any Involuntary Termination of
the employment relationship. Employee covenants not to sue or lodge any claim,
demand or cause of action against Employer for any sums for Involuntary
Termination other than those sums specified in this Section 3.5. If Employee
breaches this covenant, Employer shall be entitled to recover from Employee all
sums expended by Employer (including costs and attorneys fees) in connection
with such suit, claim, demand or cause of action.

         3.6 Upon termination of the employment relationship as a result of
Employee's death, Employee's heirs, administrators, or legatees shall be
entitled to Employee's pro rata salary through the date of such termination and
all vested benefits and rights under other Enron benefits, incentive, and/or
compensation plan, as well as the unpaid Retention Bonuses described on Exhibit
"A," but Employee's heirs, administrators, or legatees shall not be entitled to
any individual bonuses or individual incentive compensation not yet paid to
Employee at the date of such termination.

         3.7 Upon termination of the employment relationship as a result of
Employee's incapacity, Employee shall be entitled to his or her pro rata salary
through the date of such termination and all vested benefits and rights under
other Enron benefits, incentive, and/or compensation plan, as well as the unpaid
Retention Bonuses described on Exhibit "A," but Employee shall not be entitled
to any individual bonuses or individual incentive compensation not yet paid to
Employee at the date of such termination.

         3.8 In all cases, the compensation and benefits payable to Employee
under this Agreement upon termination of the employment relationship shall be
offset against any amounts to which Employee may otherwise be entitled under any
and all benefit plans and policies of Employer, Enron, or its affiliates.
Employee is eligible for benefits under Employer's severance plans, if
applicable.

         3.9 Termination of the employment relationship does not terminate those
obligations imposed by this Agreement which are continuing obligations,
including, without limitation, Employee's obligations under Articles 5 and 6.



                                      -6-

ARTICLE 4: CONTINUATION OF EMPLOYMENT BEYOND TERM; 
           TERMINATION AND EFFECTS OF TERMINATION:

         4.1 Should Employee remain employed by Employer beyond the expiration
of the Term specified on Exhibit "A," such employment shall convert to a
month-to-month relationship terminable at any time by either Employer or
Employee for any reason whatsoever, with or without cause. Upon such termination
of the employment relationship by either Employer or Employee for any reason
whatsoever, all future compensation to which Employee is entitled and all future
benefits for which Employee is eligible shall cease and terminate. Employee
shall be entitled to pro rata salary through the date of such termination, but
Employee shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination, other than vested
benefits and/or rights under other Enron benefit, incentive, and/or compensation
plans, pursuant to the terms of the applicable plan documents.

ARTICLE 5: OWNERSHIP AND PROTECTION OF INFORMATION; COPYRIGHTS:

         5.1 All information, ideas, concepts, improvements, discoveries, and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by Employee, individually or in conjunction with others, during
Employee's employment by Employer (whether during business hours or otherwise
and whether on Employer's premises or otherwise) which relate to Employer's
business, products or services (including, without limitation, all such
information relating to corporate opportunities, research, financial and sales
data, pricing and trading terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the
identity of key contacts within the customer's organizations or within the
organization of acquisition prospects, or marketing and merchandising
techniques, prospective names, and marks) shall be disclosed to Employer and are
and shall be the sole and exclusive property of Employer. Moreover, all
drawings, memoranda, notes, records, files, correspondence, drawings, manuals,
models, specifications, computer programs, maps and all other writings or
materials of any type embodying any of such information, ideas, concepts,
improvements, discoveries, and inventions are and shall be the sole and
exclusive property of Employer.

         5.2 Employee acknowledges that the business of Employer, Enron, and
their affiliates is highly competitive and that their strategies, methods,
books, records, and documents, their technical information concerning their
products, equipment, services, and processes, procurement procedures and pricing
techniques, the names of and other information (such as credit and financial
data) concerning their customers, investors and business affiliates, all
comprise confidential business information and trade secrets which are valuable,
special, and unique assets which Employer, Enron, or their affiliates use in
their business to obtain a competitive advantage over their competitors.
Employee further acknowledges that protection of such confidential business
information and trade secrets against unauthorized disclosure and use is of
critical importance to Employer, Enron, and their affiliates in maintaining
their competitive position. Employee hereby agrees that Employee will not, at
any time during or after his or her employment by Employer, make any
unauthorized disclosure of any confidential business information or trade
secrets of Employer, Enron, or their affiliates, or make any use thereof, 



                                      -7-
<PAGE>   8

except in the carrying out of his or her employment responsibilities hereunder.
Enron and its affiliates shall be third party beneficiaries of Employee's
obligations under this Section. As a result of Employee's employment by
Employer, Employee may also from time to time have access to, or knowledge of,
confidential business information or trade secrets of third parties, such as
actual and potential customers, suppliers, partners, joint venturers, investors,
financing sources and the like, of Employer, Enron, and their affiliates.
Employee also agrees to preserve and protect the confidentiality of such third
party confidential information and trade secrets to the same extent, and on the
same basis, as Employer's confidential business information and trade secrets.
Employee acknowledges that money damages would not be sufficient remedy for any
breach of this Article 5 by Employee, and Employer shall be entitled to enforce
the provisions of this Article 5 by terminating any payments then owing to
Employee under this Agreement and/or to specific performance and injunctive
relief as remedies for such breach or any threatened breach. Such remedies shall
not be deemed the exclusive remedies for a breach of this Article 5, but shall
be in addition to all remedies available at law or in equity to Employer,
including the recovery of damages from Employee and his or her agents involved
in such breach.

         5.3 All written materials, records, and other documents made by, or
coming into the possession of, Employee during the period of Employee's
employment by Employer which contain or disclose confidential business
information or trade secrets of Employer, Enron, or their affiliates shall be
and remain the property of Employer, Enron, or their affiliates, as the case may
be. Upon termination of Employee's employment by Employer, for any reason,
Employee promptly shall deliver the same, and all copies thereof, to Employer.

         5.4 If, during Employee's employment by Employer, Employee creates any
original work of authorship fixed in any tangible medium of expression which is
the subject matter of copyright (such as videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures, or the like) relating to Employer's business,
products, or services, whether such work is created solely by Employee or
jointly with others (whether during business hours or otherwise and whether on
Employer's premises or otherwise), Employee shall disclose such work to
Employer. Employer shall be deemed the author of such work if the work is
prepared by Employee in the scope of his or her employment; or, if the work is
not prepared by Employee within the scope of his or her employment but is
specially ordered by Employer as a contribution to a collective work, as a part
of a motion picture or other audio-visual work, as a translation, as a
supplementary work, as a compilation, or as an instructional text, then the work
shall be considered to be work made for hire and Employer shall be the author of
the work. If such work is neither prepared by the Employee within the scope of
his or her employment nor a work specially ordered and is deemed to be a work
made for hire, then Employee hereby agrees to assign, and by these presents does
assign, to Employer all of Employee's worldwide right, title, and interest in
and to such work and all rights of copyright therein.

         5.5 Both during the period of Employee's employment by Employer and
thereafter, Employee shall assist Employer and its nominee, at any time, in the
protection of Employer's worldwide right, title, and interest in and to
information, ideas, concepts, improvements, discoveries, and inventions, and its
copyrighted works, including without limitation, the 



                                      -8-
<PAGE>   9

execution of all formal assignment documents requested by Employer or its
nominee and the execution of all lawful oaths and applications for applications
for patents and registration of copyright in the United States and foreign
countries.

ARTICLE 6:  POST-EMPLOYMENT NON-COMPETITION OBLIGATIONS:

         6.1 Employer shall provide Employee with Confidential Information as
described above. To protect the confidential business information and trade
secrets described in Section 5 above, and as an additional incentive for
Employer to enter into this Agreement, Employer and Employee agree to the
non-competition provisions of this Article. Employee agrees that during the
period of Employee's non-competition obligations thereunder, Employee will not,
directly or indirectly, for Employee or for others, in any State of the United
States in which Employer is qualified to do business or in any foreign country
in which Employer has an office as of the date of termination of the employment
relationship:

                  a. engage in any business engaged by Employer, Enron, or their
         affiliates during the Term including, but not limited to, buying,
         selling, trading, structuring or execution of transactions in paper,
         pulp, packaging, metals, interest rates, currencies, securities, or
         other commodities (including, without limitation, energy commodities),
         or any futures, derivatives, or equities related to any of the
         foregoing, whether at wholesale or retail, or the development of
         systems, information technology, accounting or risk management with
         respect to any of the foregoing;

                  b. render advice or services to, or otherwise assist, any
         other person, association, or entity who is engaged, directly or
         indirectly, in any business engaged by Employer, Enron, or their
         affiliates during the Term, including, but not limited to, buying,
         selling, trading, structuring or execution of transactions in paper,
         pulp, packaging, metals, interest rates, currencies, securities, or
         other commodities (including, without limitation, energy commodities)
         or any futures, derivatives, or equities related to any of the
         foregoing, whether at wholesale or retail, or the development of
         systems, information technology, accounting or risk management with
         respect to any of the foregoing; or

                  c. engage in any other business in which Employer, Enron, or
         their affiliates have engaged during the Term, including, but not
         limited to, acquiring or disposing of assets or equity investments or
         providing or raising capital, through loans, equity, joint ventures,
         partnerships, working interests, production payments or similar
         arrangements that have been or will be pursued by Employer.

                  d. render advice or services to, or otherwise assist, any
         other person, association or entity, in any other business in which
         Employer, Enron, or their affiliates have engaged during the Term,
         including, but not limited to, the business of procuring or delivering
         paper, pulp, packaging, metals, interest rates, currencies, securities,
         or other commodities (including, without limitation, energy
         commodities) or providing or raising 



                                      -9-
<PAGE>   10

         capital, through loans, equity, joint ventures, partnerships, working
         interests, production payments or similar arrangements;

The non-competition obligations in Section 6.1a., b., c., and d., shall extend
throughout the Term of this Agreement and for a period of six (6) months after
the expiration of the Term of this Agreement; provided, however, that in the
event that Employee is involuntarily terminated pursuant to Section 3.1b. or
3.2a, Employee's obligations under this Section 6.1 shall continue for six (6)
months after the date of such Involuntarily Termination. If, after that
six-month period has elapsed, Employee commences employment that violates
Section 6.1a., b., c., or d., then Employer's obligation to pay Employee under
Section 3.5 shall cease as of the first day of such employment by Employee.

         6.2 Employee agrees that she will not call on, service, and/or solicit
competing business on behalf of another entity from customers of Employer,
Enron, or their affiliates for the Term of this Agreement and for a period of
twelve (12) months thereafter.

         6.3 During the Term of this Agreement, and for a period of twelve (12)
months thereafter, Employee will not, either directly or indirectly, call on,
solicit or induce any other employee of Employer, Enron, or their affiliates to
terminate their employment and will not assist in the hiring of any such
employee by any other person or entity not affiliated with Employer, Enron, or
their affiliates.

         6.4 Employee understands that the foregoing restrictions may limit his
or her ability to engage in certain businesses in the United States and/or any
country in which Employer is doing business during the period provided for
above, but acknowledges that Employer has a need to protect the confidential
business information and trade secrets of Employer. Employee also acknowledges
that she will receive sufficiently high remuneration and other benefits (e.g.,
the right to receive compensation under Section 3.5 for the remainder of the
Term upon Involuntary Termination) under this Agreement to justify such
restriction. Employee acknowledges that money damages would not be sufficient
remedy for any breach of this Article 6 by Employee, and that Employer shall be
entitled to enforce the provisions of this Article 6 by terminating any payments
then owing to Employee under this Agreement and/or to specific performance and
injunctive relief as remedies for such breach or any threatened breach. Such
remedies shall not be deemed the exclusive remedies for a breach of this Article
6, but shall be in addition to all remedies available at law or in equity to
Employer, including, without limitation, the recovery of damages from Employee
and his or her agents involved in such breach.

         6.5 It is expressly understood and agreed that Employer and Employee
consider the restrictions contained in this Article 6 to be reasonable and
necessary to protect the proprietary information of Employer. 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.



                                      -10-
<PAGE>   11

         6.6 Nothing in Article 6 shall be construed to prohibit Employee from
engaging in the private practice of law during the term of the restrictive
covenants described herein, provided, however, that Employee will not accept a
position as an in-house lawyer with a competitor of ECT, Enron, or its
affiliates, and that Employee will not use the practice of law as a subterfuge
to circumvent the requirements of Article 6.

         6.7 Nothing in Article 6 shall be construed to prohibit Employee from
engaging in personal, noncompetitive transactions such as the purchase and/or
sale of her home or the management of her personal investments so long as the
transactions are not used as a subterfuge to circumvent the requirements of
Article 6.

ARTICLE 7:  MISCELLANEOUS:

         7.1 For purposes of this Agreement the terms "affiliates" or
"affiliated" means an entity who directly, or indirectly through one or more
intermediaries, controls, is controlled by, or is under common control with
Enron or Employer.

         7.2 Employee shall refrain, both during the employment relationship and
after the employment relationship terminates, from publishing any oral or
written statements about Employer, Enron, any of their respective subsidiaries
or affiliates, or any of such entities' officers, employees, agents or
representatives that are slanderous, libelous, or defamatory; or that disclose
private or confidential information about Employer, Enron, any of their
respective subsidiaries or affiliates, or any of such entities' business
affairs, officers, employees, agents, or representatives; or that constitute an
intrusion into the seclusion or private lives of Employer, Enron, any of their
respective subsidiaries or affiliates, or such entities' officers, employees,
agents, or representatives; or that give rise to unreasonable publicity about
the private lives of Employer, Enron, any of their respective subsidiaries or
affiliates, or any of such entities' officers, employees, agents, or
representatives; or that place Employer, Enron, any of their respective
subsidiaries or affiliates, or any of such entities' or its officers, employees,
agents, or representatives in a false light before the public; or that
constitute a misappropriation of the name or likeness of Employer, Enron, any of

provide for assignment of the Employment Agreement by Company to, and assumption
of the Employment Agreement by, Azurix Corp., and to make other amendments to
the Employment Agreement as provided herein;

         NOW, THEREFORE, in consideration thereof and of the mutual covenants
contained herein, the parties agree as follows:

                  1. Effective September 1, 1998, the Employment Agreement is
         assigned by Company to, and assumed by, Azurix Corp. Any reference to
         the "Company" and/or "Employer" in the Employment Agreement shall mean

         releases Company from every obligation under the Employment Agreement.
         Azurix Corp. assumes every obligation of Company under the Employment
         Agreement.

                  2. Exhibit "A" to the Employment Agreement is hereby deleted
         in its entirety and the attached Exhibit "A" is inserted in its
         entirety.

                  3. Article 3, Section 3.5 is hereby deleted in its entirety
         and the following language shall be inserted in its place:

         "3.5 Upon an Involuntary Termination of the employment relationship by
         either Employer or Employee prior to the expiration of the Term,
         Employee shall be entitled, in consideration of Employee's continuing
         obligations hereunder after such termination (including, without
         limitation, Employee's non-competition obligations), to receive the
         compensation specified in Section 2.1, as well as unpaid Bonuses
         described on Exhibit "A", as if Employee's employment (which shall
         cease on the date of such Involuntary Termination) had continued for
         the full Term of this Agreement Upon an Involuntary Termination,
         Employee shall also be entitled to all vested benefits and rights under
         other Enron benefits, incentive, and/or compensation plans to which
         Employee may be entitled through her termination and pursuant to plan
         documents and all other benefits that Employee may be entitled to under
         any other compensation plans. In the event of Involuntary Termination,
         the compensation specified in Section 2.1 that will be paid to Employee
         will be paid on a semi-monthly basis; the unpaid Bonuses described in
         Exhibit

         "A" will be paid annually and the amounts under the compensation plans
         will be paid in accordance with the terms and provisions of the
         respective compensation plans. Employee shall not be under any duty or
         obligation to seek or accept other employment following Involuntary
         Termination and the amounts due Employee hereunder shall not be reduced
         or suspended if Employee accepts subsequent employment. Employee's
         rights under this Section 3.5 are Employee's sole and exclusive rights
         against Employer, Enron, or their affiliates, and Employer's sole and
         exclusive liability to Employee under this Agreement, in contract,
         tort, or otherwise, for any Involuntary Termination of the employment
         relationship. Employee covenants not to sue or lodge any claim, demand
         or cause of action against Employer for any sums for Involuntary
         Termination other than those sums specified in this Section 3.5. If
         Employee breaches this covenant, Employer shall be entitled to recover
         from Employee all sums expended by Employer (including costs and
         attorneys fees) in connection with such suit, claim, demand or cause of
         action."


                  4. Article 3, Sections 3.6, 3.7, and 3.8 of the Employment
         Agreement are deleted in its entirety and the following inserted in its
         entirety:

                  "3.6 Upon termination of the employment relationship as a
         result of Employee's death, Employee's heirs, administrators, or
         legatees shall be entitled to Employee's pro rata salary through the
         date of such termination, and all vested benefits and rights under
         other Enron or Company benefits, incentive, and/or compensation plans,
         as well as the unpaid pro rata Bonuses described on Exhibit "A" up to
         the date of death.

                  3.7 Upon termination of the employment relationship as a
         result of Employee's incapacity, Employee shall be entitled to his or
         her pro rata salary through the date of such termination, and all
         vested benefits and rights under other Enron or Company benefits,
         incentive, and/or compensation plans, as well as the unpaid pro rata
         Bonuses described on Exhibit "A" up to the date of incapacity.

                  3.8 In all cases, the compensation and benefits payable to
         Employee under this Agreement upon termination of the employment
         relationship shall be in addition to any amounts to which Employee may
         otherwise be entitled under any and all benefit plans and programs of
         Employer, Enron, or its affiliates; provided however, Employee shall
         not be entitled to any benefits under Employer or Enron's severance
         plans.

                  5. Article 6, Sections 6.1 and 6.2 of the Employment Agreement
         are hereby deleted in its entirety and the following is inserted in its
         entirety:

         "6.1 Employer shall provide Employee with Confidential Information as
         described above. To protect the confidential business information and
         trade secrets described in Section 5 above, and as an additional
         incentive for Employer to enter into this Agreement, Employer and
         Employee agree to the non-competition provisions of this Article.
         Employee agrees that during the period of Employee's non-competition
         obligations thereunder, Employee will not, directly



                                      -2-

         or indirectly for Employee or for others, in any State of the United
         States in which Employer is qualified to do business or in any foreign
         country in which Employer has an office as of the date of termination
         of the employment relationship engage in any business engaged by
         Employer, Enron, or their affiliates during the Term related to the
         water business. The non-competition obligations in Section 6.1 shall
         extend throughout the Term of this Agreement and for a period of six
         (6) months after the expiration of this Agreement; provided, however,
         that in the event Employee is involuntarily terminated pursuant to
         Section 3.1b. or 3.2a, Employee's obligations under this Section 6.1
         shall continue for six (6) months after the date of such Involuntary
         Termination. If, after that six-month period has elapsed, Employee
         commences employment that violates Section 6.1, then Employer's
         obligation to pay Employee under Section 3.5 shall cease as of the
         first day of such employment by Employee.

                  6.2 Employee agrees that she will not call on, service, and/or
         solicit competing business on behalf of another entity from customers
         of Employer, Enron, or their affiliates in the water business for the
         Term of this Agreement and for a period of twelve (12) months
         thereafter."

         This Amendment is a First Amendment to the Employment Agreement, and
the parties agree that all other terms, conditions and stipulations contained in
the Employment Agreement, and any amendments thereto, shall remain in full force
and effect and without any change or modification, except as provided herein.

the date first above written.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Employment Agreement ("Agreement"), including the attached Exhibit
"A," is entered into between Azurix Corp., a Delaware corporation, ("Employer")
and subsidiary of ENRON CORP., an Oregon corporation, having offices at 1400
Smith Street, Houston, Texas 77002 ("Enron"), and ALEX KULPECZ, an individual
currently residing at 2 Midgarth Close Oxshott, Surrey UNITED KINGDOM KT22 0JY
("Employee"), to be effective as of September 15, 1998 (the "Effective Date").

                                   WITNESSETH:

         WHEREAS, Employer is desirous of employing Employee pursuant to the
terms and conditions and for the consideration set forth in this Agreement, and
Employee is desirous of entering the employ of Employer pursuant to such terms
and conditions and for such consideration.

         NOW, THEREFORE, for and in consideration of the mutual promises,
covenants, and obligations contained herein, Employer and Employee agree as
follows:

ARTICLE 1: EMPLOYMENT AND DUTIES:

         1.1   Employer agrees to employ Employee, and Employee agrees to be
employed by Employer, beginning as of the Effective Date and continuing until
the date set forth on Exhibit "A" (the "Term"), subject to the terms and
conditions of this Agreement.

         1.2   Employee initially shall be employed in the position set forth on
Exhibit A. Employer may subsequently assign Employee to a different position or
modify Employee's duties and responsibilities. Moreover, Employer may assign
this Agreement and Employee's employment to Enron or any affiliates of Enron.
Employee agrees to serve in the assigned position and to perform diligently and
to the best of Employee's abilities the duties and services appertaining to such
position as determined by Employer, as well as such additional or different
duties and services appropriate to such position which Employee from time to
time may be reasonably directed to perform by Employer. Employee shall at all
times comply with and be subject to such policies and procedures as Employer may
establish from time to time.

         1.3   Employee shall, during the period of Employee's employment by
Employer, devote Employee's full business time, energy, and best efforts to the
business and affairs of Employer. Employee may not engage, directly or
indirectly, in any other business, investment, or activity that interferes with
Employee's performance of Employee's duties hereunder, is contrary to the
interests of Employer or Enron, or requires any significant portion of
Employee's business time.

         1.4   In connection with Employee's employment by Employer, Employer
shall endeavor to provide Employee access to such confidential information
pertaining to the business and services of Employer as is appropriate for
Employee's employment responsibilities. 

                                       1

<PAGE>   2

Employer also shall endeavor to provide to Employee the opportunity to develop
business relationships with those of Employer's clients and potential clients
that are appropriate for Employee's employment responsibilities.

         1.5   Employee acknowledges and agrees that, at all times during the
employment relationship Employee owes fiduciary duties to Employer, including
but not limited to the fiduciary duties of the highest loyalty, fidelity and
allegiance to act at all times in the best interests of the Employer, to make
full disclosure to Employer of all information that pertains to Employer's
business and interests, to do no act which would injure Employer's business, its
interests, or its reputation, and to refrain from using for Employee's own
benefit or for the benefit of others any information or opportunities pertaining
to Employer's business or interests that are entrusted to Employee or that he
learned while employed by Employer. Employee acknowledges and agrees that upon
termination of the employment relationship, Employee shall continue to refrain
from using for his own benefit or the benefit of others any information or
opportunities pertaining to Employer's business or interests that were entrusted
to Employee during the employment relationship or that he learned while employed
by Employer. Employee agrees that while employed by Employer and thereafter he
shall not knowingly take any action which interferes with the internal
relationships between Employer and its employees or representatives or
interferes with the external relationships between Employer and third parties.

         1.6   It is agreed that any direct or indirect interest in, connection
with, or benefit from any outside activities, particularly commercial
activities, which interest might in any way adversely affect Employer or any of
its affiliates, involves a possible conflict of interest. In keeping with
Employee's fiduciary duties to Employer, Employee agrees that during the
employment relationship Employee shall not knowingly become involved in a
conflict of interest with Employer or its affiliates, or upon discovery thereof,
allow such a conflict to continue. Moreover, Employee agrees that Employee shall
disclose to Employer's President any facts which might involve such a conflict
of interest that has not been approved by Employer's President. Employer and
Employee recognize that it is impossible to provide an exhaustive list of
actions or interests which constitute a "conflict of interest." Moreover,
Employer and Employee recognize there are many borderline situations. In some
instances, full disclosure of facts by the Employee to Employer's President may
be all that is necessary to enable Employer or its affiliates to protect its
interests. In others, if no improper motivation appears to exist and the
interests of Employer or its affiliates have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for
Employer to terminate the employment relationship. Employer and Employee agree
that Employer's determination as to whether a conflict of interest exists shall
be conclusive. Employer reserves the right to take such action as, in its
judgment, will end the conflict.

         1.7   Employee understands and acknowledges that the terms and 
conditions of this Agreement constitute confidential information. Employee shall
keep confidential the terms of this Agreement and shall not disclose this
confidential information to anyone other than Employee's attorneys, tax
advisors, or as required by law. Employee acknowledges and understands that
disclosure of the terms of this Agreement constitutes a material breach of this
Agreement and could subject Employee to disciplinary action, including without
limitation, termination of employment.

ARTICLE 2: COMPENSATION AND BENEFITS:

         2.1   Employee's monthly base salary during the Term shall be not less
than the amount set forth under the heading "Monthly Base Salary" on Exhibit A,
subject to increase at the sole discretion of the Employer, which shall be paid
in semimonthly installments in accordance with Employer's standard payroll
practice. Any calculation to be made under this Agreement with respect to
Employee's Monthly Base Salary shall be made using the then current Monthly Base
Salary in effect at the time of the event for which such calculation is made.

         2.2   While employed by Employer (both during the Term and thereafter),
Employee shall be allowed to participate, on the same basis generally as other
employees of Employer, in all general employee benefit plans and programs,
including improvements or modifications of the same, which on the effective date
or thereafter are made available by Employer to all or substantially all of
Employer's employees. Such benefits, plans, and programs may include, without
limitation, medical, health, and dental care, life insurance, disability
protection, and pension plans. Nothing in this Agreement is to be construed or
interpreted to provide greater rights, participation, coverage, or benefits
under such benefit plans or programs than provided to similarly situated
employees pursuant to the terms and conditions of such benefit plans and
programs.

         2.3   Employer shall not by reason of this Article 2 be obligated to
institute, maintain, or refrain from changing, amending, or discontinuing, any
such incentive compensation or employee benefit program or plan, so long as such
actions are similarly applicable to covered employees generally. Moreover,
unless specifically provided for in a written plan document adopted by the Board
of Directors of either Employer or Enron, none of the benefits or arrangements
described in this Article 2 shall be secured or funded in any way, and each
shall instead constitute an unfunded and unsecured promise to pay money in the
future exclusively from the general assets of Employer.

         2.4   Employer may withhold from any compensation, benefits, or amounts
payable under this Agreement all federal, state, city, or other taxes as may be
required pursuant to any law or governmental regulation or ruling.

         2.5   In addition to all other compensation payable under this 
Agreement to Employee, Employer shall also cause Employee to receive:

         (i)   an option to purchase 100,000 shares of Enron Corp. Common
               Stock. The grant shall be effective and the grant price shall
               be equal to the closing price of Enron Corp. Common Stock on
               the date on which Employee commences employment under this
               Agreement; the grant shall have an exercise term of ten years
               from date of grant and shall be evidenced by an award
               agreement in the form attached as Exhibit "B"; such option to
               vest at the rate of 33 1/3% annually beginning on the first

               anniversary of the date of grant; if Employee and Employer
               mutually agree, this option may be converted in whole or in
               part into an option to purchase a comparable value of stock in
               Employer;

         (ii)  a lump sum signing bonus of $250,000.00, fully earned by
               Employee upon payment thereof, payable in full on a fully
               tax-protected basis for both U.S. and U.K. purposes on or
               before the expiration of 30 days following the date on which
               Employee commences employment under this Agreement;

         (iii) an option to purchase 30,000 shares of Enron Corp. Common
               Stock. The grant shall be effective and the grant price shall
               be equal to the closing price of Enron Corp. Common Stock on
               the date on which Employee commences employment under this
               Agreement; such option to be 100% vested upon date of grant;

         (iv)  a performance bonus under the Enron Corp. Annual Incentive
               Bonus Plan (or, a replacement Employer performance bonus
               plan), with a target bonus for 1999 and future years equal to
               100% of Monthly Base Salary multiplied times 12 ("Annual Base
               Salary"). For 1998, Employee's target bonus shall be 50% of
               his Annual Base Salary if employment begins in September 1998,
               based upon Enron Corp.'s achievement of net income relative to
               its target and Employee's achievement of his Performance
               Objectives; for 1999 and future years, participation shall be
               based on Employer's achievement of net income and/or other
               financial measures relative to pre-established targets and
               Employee's achievement of his Performance Objectives;
               provided, however, Employer's Chairman and Employee shall
               negotiate specific Employer and Employee performance targets
               and specific relationships of Employee's bonuses to the
               Employer's and Employee's actual performance with respect to
               such targets; and

         (v)   the other items of compensation listed on Exhibit "A".

ARTICLE 3: TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF SUCH 
           TERMINATION:

         3.1.  Notwithstanding any other provisions of this Agreement, Employer
shall have the right to terminate Employee's employment under this Agreement at
any time prior to the expiration of the Term for any of the following reasons:

         (i)   For "cause" upon the determination by the Employer's
               management committee (or, if there is no management committee,
               the highest applicable level of management) that "cause"
               exists for the termination of the employment relationship. As
               used in this Section 3.1(i), the term "cause" shall mean [a]
               Employee's gross negligence or willful misconduct in the
               performance of the duties and services required of Employee
               pursuant to this Agreement; [b] Employee has been convicted of
               a felony; [c] Employee has willfully refused without proper
               legal reason to perform the duties and responsibilities
               required of 

                                       4

<PAGE>   5

               Employee under this Agreement which remains uncorrected for
               thirty (30) days following written notice to Employee by
               Employer of such breach; [d] Employee's involvement in a
               conflict of interest as referenced in Section 1.6 for which
               Employer makes a determination to terminate the employment of
               Employee which remains uncorrected for thirty (30) days
               following written notice to Employee by Employer of such
               breach; [e] Employee has willfully engaged in conduct that
               Employee knows or should know is materially injurious to
               Employer, Enron, or any of their respective subsidiaries; [f]
               Employee's material breach of any material provision of this
               Agreement or corporate code or policy which remains
               uncorrected for thirty (30) days following written notice to
               Employee by Employer of such breach; or [g] Employee violates
               the Foreign Corrupt Practices Act or other applicable United
               States law as proscribed by Section 5.1. It is expressly
               acknowledged and agreed that the decision as to whether
               "cause" exists for termination of the employment relationship
               by Employer is delegated to the Employer's management
               committee (or, if there is no management committee, the
               highest applicable level of Employer's management) for
               determination. If Employee disagrees with the decision reached
               by Employer's management committee (or, if there is no
               management committee, the highest applicable level of
               Employer's management), the dispute will be limited to whether
               Employer's management committee (or, if there is no Enron
               management committee, the highest applicable level of
               Employer's management) reached its decision in good faith;

         (ii)  [a] for any other reason whatsoever, with or without cause, in
               the sole discretion of the management committee (or, if there
               is no management committee, the highest applicable level of
               management) of Employer; or [b] Employee's failure to meet his
               material specific Performance Objectives as established from
               time to time by Employer, as reasonably determined by the
               Chairman of Employer;

         (iii) upon Employee's death; or

         (iv)  upon Employee's becoming disabled so as to entitle Employee to
               benefits under Enron's long-term disability plan or, if
               Employee is not eligible to participate in such plan, then
               Employee is permanently and totally unable to perform
               Employee's duties for Employer as a result of any medically
               determinable physical or mental impairment as supported by a
               written medical opinion to the foregoing effect by a physician
               selected by Employer.

The termination of Employee's employment by Employer prior to the expiration of
the Term shall constitute a "Termination for Cause" if made pursuant to Section
3.1(i); the effect of such termination is specified in Section 3.4. The
termination of Employee's employment by Employer prior to the expiration of the
Term shall constitute an "Involuntary Termination" if made pursuant to Section
3.1(ii); the effect of such termination is specified in Section 3.5. The effect
of the employment relationship being terminated pursuant to Section 3.1(iii) as
a result of Employee's death is specified in Section 3.6. The effect of the
employment relationship being terminated pursuant to Section 3.1(iv) as a result
of the Employee becoming incapacitated is specified in Section 3.7.

Term of employment for any of the following reasons:

         (i)   a material breach by Employer of any material provision of
               this Agreement which remains uncorrected for 30 days following
               written notice of such breach by Employee to Employer;

         (ii)  within sixty (60) days of and in connection with or based upon
               any of the following:

               [a]  a transfer of assignment from Employee's present
                    position to a position which involves an overall
                    reduction in the nature or scope of Employee's duties
                    and responsibilities which is not performance
                    related;

               [b]  a relocation of Employee from the city in which
                    Employee was serving at the time of such change to a
                    place which is more than 50 miles away from such
                    location;

               [c]  sale or other disposition of Employer by Enron Corp.
                    or the sale or other disposition of a material amount
                    of Employer's assets, such that Employer is no longer
                    affiliated with Enron Corp., except when Employer
                    becomes a separate publicly traded company;

               [d]  the decision by Enron Corp. to discontinue the
                    development and/or expansion of the Employer's
                    business or the failure, irrespective of any such
                    decision, of Employer to continue the development and
                    or expansion; or

         (iii) for any other reason whatsoever, in the sole discretion of
               Employee.

The termination of Employee's employment by Employee prior to the expiration of
the Term shall constitute an "Involuntary Termination" if made pursuant to
Section 3.2(i) or 3.2(ii); the effect of such termination is specified in
Section 3.5. The termination of Employee's employment by Employee prior to the
expiration of the Term shall constitute a "Voluntary Termination" if made
pursuant to Section 3.2(iii); the effect of such termination is specified in
Section 3.3.

         3.3   Upon a "Voluntary Termination" of the employment relationship by
Employee prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible
shall cease and terminate as of the date of termination. Employee shall be
entitled to pro rata salary through the date of such termination, but Employee
shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

                                       6

<PAGE>   7

         3.4   If Employee's employment hereunder shall be terminated by 
Employer for Cause prior to expiration of the Term, all future compensation to
which Employee is entitled and all future benefits for which Employee is
eligible shall cease and terminate as of the date of termination. Employee shall
be entitled to pro rata salary through the date of such termination, but
Employee shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

         3.5   Upon an Involuntary Termination of the employment relationship by
either Employer or Employee under Section 3.2(i) or (ii) prior to the expiration
of the Term, Employee shall be entitled, in consideration of Employee's
continuing obligations hereunder after such termination (including, without
limitation, Employee's non-competition obligations, except as expressly provided
to the contrary), to the compensation specified in Section 2.1, as if Employee's
employment (which shall cease on the date of such Involuntary Termination) had
continued for the full Term of this Agreement; housing allowance and educational
assistance for Employee's children at assignment to continue through higher
education as specified in the September 9, 1998 Employment Offer Letter and
Exhibit 1 attached thereto through the end of the Term; and 100% of the bonus
provided in Section 2.5(iv) prorated through the end of the calendar year in
which such termination occurs. In addition, Employee shall receive One Million
Dollars minus the value of equity described at Section 2.5(i) which includes
potential future grants of stock or stock options by Employer or Enron Corp.,
such value to be determined in accordance with the applicable stock equity
plan(s) document(s) and shall include a reduction for broker fees to sell the
shares; provided however, if the Involuntary Termination is due to Employee's
failure to meet his material specific Performance Objectives under Section
3.1(ii)[b] as determined by Employer's Chairman, Employee shall only receive the
remainder of the Monthly Base Pay due under the Term of the Agreement, plus
housing allowance and educational assistance for Employee's children at

rights under this Section 3.5 are Employee's sole and exclusive rights against
Employer, Enron, or their affiliates, and Employer's sole and exclusive
liability to Employee under this Agreement, in contract, tort, or otherwise, for
any Involuntary Termination of the employment relationship. Employee covenants
not to sue or lodge any claim, demand or cause of action against Employer for
any sums for Involuntary Termination other than those sums specified in this
Section 3.5. If Employee breaches this covenant, Employer shall be entitled to
recover from Employee all sums expended by Employer (including costs and
attorneys fees) in connection with such suit, claim, demand or cause of action.

entitled to Employee's pro rata salary through the date of such termination, but
Employee's heirs, administrators, or legatees shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.7   Upon termination of the employment relationship as a result of
Employee's incapacity, Employee shall be entitled to his or her pro rata salary
through the date of such termination, but Employee shall not be entitled to any
individual bonuses or individual incentive compensation not yet paid to Employee
at the date of such termination.

         3.8   In all cases, the compensation and benefits payable to Employee
under this Agreement upon termination of the employment relationship shall be
offset against any amounts to which Employee may otherwise be entitled under any
and all severance plans, and policies of Employer, Enron, or its affiliates.

         3.9   Termination of the employment relationship does not terminate 
those obligations imposed by this Agreement which are continuing obligations,
including, without limitation, Employee's obligations under Articles 6 and 7.

ARTICLE 4: CONTINUATION OF EMPLOYMENT BEYOND TERM; TERMINATION AND EFFECTS OF
           TERMINATION:

         4.1   Should Employee remain employed by Employer beyond the expiration
of the Term specified on Exhibit "A," such employment shall convert to a
month-to-month relationship terminable at any time by either Employer or
Employee for any reason whatsoever, with or without cause. Upon such termination
of the employment relationship by either Employer or Employee for any reason
whatsoever, all future compensation to which Employee is entitled and all future
benefits for which Employee is eligible shall cease and terminate. Employee
shall be entitled to pro rata salary through the date of such termination, but
Employee shall not be entitled to any individual bonuses or individual incentive
compensation not yet paid at the date of such termination.

ARTICLE 5: UNITED STATES FOREIGN CORRUPT PRACTICES ACT AND OTHER LAWS:

         5.1.  Employee shall at all times comply with United States laws
applicable to Employee's actions on behalf of Employer, including specifically,
without limitation, the United States Foreign Corrupt Practices Act, generally
codified in 15 USC 78 (FCPA), as the FCPA may hereafter be amended, and/or its
successor statutes. If Employee pleads guilty to or nolo contendere or admits
civil or criminal liability under the FCPA or other applicable United States
law, or if a court finds that Employee has personal civil or criminal liability
under the FCPA or other applicable United States law, or if a court finds that
Employee committed an action resulting in any Enron entity having civil or
criminal liability or responsibility under the FCPA or other applicable United
States law with knowledge of the activities giving rise to such liability or
knowledge of facts from which Employee should have reasonably inferred the
activities giving rise to liability had occurred or were likely to occur, such
action or finding shall constitute "cause" for termination under this Agreement
unless Employer's management committee (or, if there is no management committee,
the highest applicable level of Employer's management) determines that the
actions found to be in violation of the FCPA or other applicable United States
law were taken in good faith and in compliance with all applicable policies of
Employer and Enron.

ARTICLE 6: OWNERSHIP AND PROTECTION OF INFORMATION; COPYRIGHTS:

         6.1   All information, ideas, concepts, improvements, discoveries, and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by Employee, individually or in conjunction with others, during
Employee's employment by Employer (whether during business hours or otherwise
and whether on Employer's premises or otherwise) which relate to Employer's
business, products or services (including, without limitation, all such
information relating to corporate opportunities, research, financial and sales
data, pricing and trading terms, evaluations, opinions, interpretations,
acquisition prospects, the identity of customers or their requirements, the
identity of key contacts within the customer's organizations or within the
organization of acquisition prospects, or marketing and merchandising
techniques, prospective names, and marks) shall be disclosed to Employer and are
and shall be the sole and exclusive property of Employer. Moreover, all
drawings, memoranda, notes, records, files, correspondence, drawings, manuals,
models, specifications, computer programs, maps and all other writings or
materials of any type embodying any of such information, ideas, concepts,
improvements, discoveries, and inventions are and shall be the sole and
exclusive property of Employer.

         6.2   Employee acknowledges that the business of Employer, Enron, and
their affiliates is highly competitive and that their strategies, methods,
books, records, and documents, their technical information concerning their
products, equipment, services, and processes, procurement procedures and pricing
techniques, the names of and other information (such as credit and financial
data) concerning their customers and business affiliates, all comprise
confidential business information and trade secrets which are valuable, special,
and unique assets which Employer, Enron, or their affiliates use in their
business to obtain a competitive advantage over their competitors. Employee
further acknowledges that protection of such confidential business information
and trade secrets against unauthorized disclosure and use is of critical
importance to Employer, Enron, and their affiliates in maintaining their
competitive position. Employee hereby agrees that Employee will not, at any time
during or after his or her employment by Employer, make any unauthorized
disclosure of any confidential business information or trade secrets of
Employer, Enron, or their affiliates, or make any use thereof, except in the
carrying out of his or her employment responsibilities hereunder. Enron and its
affiliates shall be third party beneficiaries of Employee's obligations under
this Section. As a result of Employee's employment by Employer, Employee may
also from time to time have access to, or knowledge of, confidential business
information or trade secrets of third parties, such as customers, suppliers,
partners, joint venturers, and the like, of Employer, Enron, and their
affiliates. Employee also agrees to preserve and protect the confidentiality of
such third party confidential information and trade secrets to the same extent,
and on the same basis, as Employer's confidential business information and trade
secrets. Employee acknowledges that money damages would not be sufficient remedy
for any breach of this Article 6 by Employee, and Employer shall be entitled to
enforce the provisions of this Article 6 by terminating any payments then owing
to Employee under this Agreement and/or to specific performance and injunctive
relief as remedies for such 

                                       9

<PAGE>   10

breach or any threatened breach. Such remedies shall not be deemed the exclusive
remedies for a breach of this Article 6, but shall be in addition to all
remedies available at law or in equity to Employer, including the recovery of
damages from Employee and his or her agents involved in such breach.

         6.3   All written materials, records, and other documents made by, or
coming into the possession of, Employee during the period of Employee's
employment by Employer which contain or disclose confidential business
information or trade secrets of Employer, Enron, or their affiliates shall be
and remain the property of Employer, Enron, or their affiliates, as the case may
be. Upon termination of Employee's employment by Employer, for any reason,
Employee promptly shall deliver the same, and all copies thereof, to Employer.

         6.4   If, during Employee's employment by Employer, Employee creates 
any original work of authorship fixed in any tangible medium of expression which
is the subject matter of copyright (such as videotapes, written presentations on
acquisitions, computer programs, drawings, maps, architectural renditions,
models, manuals, brochures, or the like) relating to Employer's business,
products, or services, whether such work is created solely by Employee or
jointly with others (whether during business hours or otherwise and whether on
Employer's premises or otherwise), Employee shall disclose such work to
Employer. Employer shall be deemed the author of such work if the work is
prepared by Employee in the scope of his or her employment; or, if the work is
not prepared by Employee within the scope of his or her employment but is
specially ordered by Employer as a contribution to a collective work, as a part
of a motion picture or other audiovisual work, as a translation, as a
supplementary work, as a compilation, or as an instructional text, then the work
shall be considered to be work made for hire and Employer shall be the author of
the work. If such work is neither prepared by the Employee within the scope of
his or her employment nor a work specially ordered and is deemed to be a work
made for hire, then Employee hereby agrees to assign, and by these presents does
assign, to Employer all of Employee's worldwide right, title, and interest in
and to such work and all rights of copyright therein.

         6.5   Both during the period of Employee's employment by Employer and
thereafter, Employee shall assist Employer and its nominee, at any time, in the
protection of Employer's worldwide right, title, and interest in and to
information, ideas, concepts, improvements, discoveries, and inventions, and its
copyrighted works, including without limitation, the execution of all formal
assignment documents requested by Employer or its nominee and the execution of
all lawful oaths and applications for applications for patents and registration
of copyright in the United States and foreign countries.

ARTICLE 7: POST-EMPLOYMENT NON-COMPETITION OBLIGATIONS:

         7.1   As part of the consideration for the compensation and benefits to
be paid to Employee hereunder, in keeping with Employee's duties as a fiduciary
and in order to protect Employer's interests in the confidential information of
Employer and the business relationships developed by Employee with the clients
and potential clients of Employer, and as an additional incentive for Employer
to enter into this Agreement, Employer and Employee agree to the non-

                                       10

<PAGE>   11

competition provisions of this Article 7. Employee agrees that during the period
of Employee's non-competition obligations hereunder, Employee will not, directly
or indirectly for Employee or for others, in any geographic area or market where
Employer 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 Employer;

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

         (iii) induce any employee of Employer or Enron or any of their
               affiliates to terminate his or her employment with Employer,
               Enron, 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 the latter of (a)
expiration of the Term or (b) one year after termination of the employment
relationship.

         7.2   Employee understands that the foregoing restrictions may limit 
his or her ability to engage in certain businesses anywhere in the world during
the period provided for above, but acknowledges that Employee will receive
sufficiently high remuneration and other benefits (e.g., the right to receive
compensation under Section 3.5 for the remainder of the Term upon Involuntary
Termination) under this Agreement to justify such restriction. Employee
acknowledges that money damages would not be sufficient remedy for any breach of
this Article 7 by Employee, and Employer shall be entitled to enforce the
provisions of this Article 7 by terminating any payments then owing to Employee
under this Agreement and/or to specific performance and injunctive relief as
remedies for such breach or any threatened breach. Such remedies shall not be
deemed the exclusive remedies for a breach of this Article 7, but shall be in
addition to all remedies available at law or in equity to Employer, including,
without limitation, the recovery of damages from Employee and his or her agents
involved in such breach.

         7.3   It is expressly understood and agreed that Employer and Employee
consider the restrictions contained in this Article 7 to be reasonable and
necessary to protect the proprietary information of Employer. 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.

               FIRST AMENDMENT TO EXECUTIVE EMPLOYMENT AGREEMENT

     This Agreement, entered into on this 11 of March, 1999, and made effective
as of 11 March, 1999, by and between AZURIX CORP., a Delaware corporation having
its headquarters at 333 Clay Street, Houston, Texas 77002, ("Employer") and ALEX
KULPECZ ("Employee"), an individual residing in the UNITED KINGDOM, is an
amendment to that certain Executive Employment Agreement between the Employer
and Employee entered into the 7th day of October, 1998, and made effective as of
September 15, 1998 (the "Employment Agreement").

     WHEREAS, the parties desire to amend the Employment Agreement to provide
for further description of target bonuses, and to make other amendments to the
Employment Agreement as provided herein;

     NOW, THEREFORE, in consideration thereof and of the mutual covenants
contained herein, the parties agree as follows:

          1. Article 2, Section 2.5 (iv) is are hereby deleted and the
             following inserted in its place:

          o "(iv)  a performance bonus under the Enron Corp. Annual Incentive
            Bonus Plan (or, a replacement Employer performance bonus plan), with
            a target bonus for 1999 and future years equal to 100% of Monthly
            Base Salary multiplied times 12 ("Annual Base Salary"). For 1998,
            Employee's target bonus shall be 50% of his Annual Base Salary if
            employment begins in September 1998, based upon Enron Corp.'s
            achievement of net income relative to its target and Employee's
            achievement of his Performance Objectives; for 1999 and future
            years, participation shall be based on Employer's achievement of
            net income and/or other financial measures relative to
            pre-established targets and Employee's achievement of his
            Performance Objectives; provided, however, Employer's Chairman
            and Employee shall negotiate specific Employer and Employee
            performance targets and specific relationships of Employee's
            bonuses to the Employer's and Employee's actual performance with
            respect to such targets; the 1999, 2000, and 2001 bonus payments
            will be offset by the increased vested value of 50,000 of the
            100,000 Enron Corp. Stock Options described herein above at
            Section 2.5(i) and such offset to be determined as follows:

               o 1999 bonus target minus the December 31, 1999 value of 16,666
                 options vested September 15, 1999

               o 2000 bonus target minus the December 31, 2000 value of 16,667
                 options vested September 15, 2000

               o 2001 bonus target minus the December 31, 2001 value of 16,667
                 options vested September 15, 2001

          For example, if the 2000 bonus target equaled $500,000.00 and the
          December 31, 2000 vested value of the 16,666 options vested September
          15, 2000 equaled $249,990.00 ($15.00 increase from exercise prior to
          12/31/00 closing price), then the 2000 bonus target would equal
          $250,010.00 ($500,000.00 minus(-) $249,990.00); and"

     This Amendment is a First Amendment to the Employment Agreement, and the
parties agree that all other terms, conditions and stipulations contained in
the Employment Agreement, and any amendments thereto, shall remain in full
force and effect and without any change or modification, except as provided
herein.

     IN WITNESS WHEREOF, the parties have duly executed this Agreement as of
the date first above written.

10.3     In 10.2 above, references to acting directly or indirectly include
         (without prejudice to the generality of that expression) references to
         acting alone or jointly with or by means of any other person.

10.4     The Employee hereby agrees that he will at the request and cost of the
         Company enter into a direct agreement or undertaking with any Group
         Company whereby he will accept restrictions and provisions
         corresponding to the restrictions and provisions above (or such of them
         as may be reasonable and appropriate in the circumstances) in relation

         12 months as such Company or Companies may reasonably require for the
         protection of its or their legitimate interest.

10.5     The Employee agrees that having regard to the facts and matters
         aforesaid the restrictive convenants herein contained are reasonably
         and necessary for the protection of the legitimate interests of the
         Company or any Group Company and the Employee agrees that having regard
         to those circumstances the convenants do not work unfairly or harshly
         on him. While the restrictions aforesaid are considered by the parties
         to be reasonable in all the circumstances it is agreed that if any such
         restriction shall be adjudged to be void or ineffective for whatever
         reason but would be adjudged to be valid and effective if part of the
         wording thereof were deleted or the periods thereof reduced or the area
         thereof reduced in scope, the said restrictions shall apply with such
         modifications as may be necessary to make them valid and effective. The
         convenants contained in 10.1 above are separate and severable and
         enforceable accordingly.

         (a)      be or become bankrupt or compound with his creditors; or

         (b)      be guilty of conduct tending to being the Company of himself
                  into disrepute; or

         (c)      commit any serious or persistent breach of any of his
                  obligations to the Company or any Group Company under this
                  Agreement; or

         (d)      become prohibited by law from being a director of any company;
                  or

         (e)      resign as director of the Company or any Group Company or in
                  the event of his retiring from that office by rotation, he
                  fails to offer himself for re-election; or

         (f)      be incapacitated from performing his duties for any continuous
                  period of 180 days or for periods exceeding 125 working days
                  in any period of 12 months.

         then the Company shall be entitled by notice in writing given within 3
         months of one of the events specified at (a) to (f) above to terminate
         his employment under this Agreement 


                                       6
<PAGE>   7

         with immediate effect whereupon the Employee shall have no claim
         against the Company for damages or otherwise by reason of such
         termination. Any termination of the employment of the Employee will be
         without prejudice to his continuing obligations under this Agreement.

11.2     Upon the termination of this Agreement for whatever reason the Employee
         shall, if so requested by the Company, forthwith resign from any
         offices held by him in the Company or any other Group Company and in
         the event of his failure to do so the Company is hereby irrevocably
         authorised to appoint some person in his name and on his behalf to so
         all such things and execute all such documents as may be necessary or
         desirable to bring about such resignation.

11.3     The Employee shall not, during the continuance of his employment
         hereunder, resign any office he had with the Company or (other than
         with the approval of the Board) any Group Company or do anything which
         would cause him to be disqualified from continuing to act as an office
         holder.

RE-ORGANISATION

12.      Should the Company (or any part of the Group of Companies of which the
         Company from time to time forms part) undergo any process of
         reconstruction, amalgamation or administrative re-organisation (whether
         or not involving the liquidation of the Company) and should in the
         process the Employee's job cease to exist or the scope or title be
         varied or it appears desirable to the Company or its Holding Company,
         if any, that the Employee should be employed by some other Group
         Company then, provided that the terms and conditions of service (other
         than the duties involved in the job) offered to the Employee in respect
         of the proposed new employment or his existing employment as varied, as
         the case may be, are, taken as a whole, not less advantageous to him
         than those contained herein and the duties thereof are within his
         capabilities and of a nature which in the circumstances it is not
         unreasonable to expect the Employee to perform, the Employee shall
         (whether or not he accepts such alternative or varied employment)
         except as allowed by statute have no claim for compensation against the
         Company in respect of the termination or variation (actual or proposed)
         of his employment hereunder.

NOTICES

13.      Any notice in writing to be served hereunder may be given personally to
         the Employee or to the Secretary of the Company (as the case may be) or
         may be posted by first class post to the Company (for the attention of
         the Secretary) or may be posted by first class post to the Company (for
         the attention of the Secretary) at its registered office for the time
         being or to the Employee at his last known address. Any such notice
         sent by post shall be deemed served 48 hours after it is posted and in
         proving such service it shall be sufficient to prove that the notice
         was properly addressed and put in the post.

24 February 1995

Dear Mr Skellett

UNFUNDED PENSION ARRANGEMENT

Further to our recent discussions, I am pleased to advise you that Wessex Water
Plc ("Wessex") has agreed to provide you with a pension under an Unfunded
Pension Arrangement. This Arrangement will provide you with benefits additional
to those provided under the Wessex Water Mirror Image Pension Scheme and the
Wessex Water Executive Pension Scheme ("the Executive Scheme").

The terms of the Unfunded Pension Arrangement are as follows:

1.       YOUR OWN RETIREMENT PENSION

         If you stay in employment with Wessex until 1 January 1000 you will
         receive an annual pension of 10% of your Final Pensionable Salary (as
         defined in the Rules of the Wessex Water Executive Pension Scheme) when
         you leave employment.

2.       YOUR SPOUSE'S PENSION

         If you die in service leaving a widow, she will receive a pension for
         life equal to 4 percent of your Final Pensionable Salary at the date of
         death.

         If you die after retirement leaving a widow, she will receive a pension
         for life of two-thirds of the pension which you were receiving under
         this Arrangement at the date of death.

3.       INCREASES OF PENSION IN PAYMENT

         Once the pension comes into payment it will be increased annually at
         the rate of 5% or the increase in the RPI if lower. Further increases
         will be awarded in line with any discretionary increases granted form
         the Executive Scheme.


                                       5

4.       LEAVING EMPLOYMENT

         If you cease to be an active member of the Wessex Water Mirror Image
         Pension Scheme and the Wessex Water Executive Pension Scheme then you
         will be treated for the purposes of this letter as having left
         employment with Wessex. If you are treated as having left employment,
         or if you leave employment with Wessex before 1 January 2000 then you
         will be entitled to a deferred pension payable form 1 January 2000
         calculated on the basis set out in column 1 of the attached schedule.
         The deferred pension will increase in deferment in accordance with
         deferred pensions payable under the Executive Scheme.

         However, if you leave employment

         a)       on the grounds of incapacity (as defined in the Executive
                  Scheme) or

         b)       if Wessex decides that there are compassionate grounds for
                  your leaving employment or

         c)       if you are required to retire by Wessex or

         d)       if you are made redundant as a result of the cancellation of
                  the listing of Wessex's securities by the London Stock
                  Exchange or

         e)       if Wessex so decides in any other case

         you will be entitled to an immediate pension calculated on the basis
         set out in Column 2 of the attached schedule and based on your Final
         Pensionable Salary at the date of leaving employment.

5.       GENERAL

         The pensions payable under this Arrangement will be treated as taxable
         income when they become due and will be payable directly by Wessex.

         Wessex may change the terms of this Arrangement at any time, but only
         with your agreement.

         this letter please sign and return the attached copy of this letter.
