                                  OUR COMPANY
 
     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. Azurix
estimates that the global water industry has total annual revenues of
approximately $300 billion. In addition, the World Bank and other sources have
estimated that over $600 billion will be spent on worldwide water and wastewater
infrastructure over the next decade. We believe that much of that capital will
come from the private sector.
 
     Enron, one of the world's leading integrated natural gas and electricity
companies, formed Azurix in 1998 to pursue opportunities in the global water
industry. Our first significant step was to acquire Wessex, a water and
wastewater company based in southwestern England, for $2.4 billion in order to
give us the operating experience necessary to compete successfully for business
around the world. Wessex's operating expertise is evidenced by the industry
regulator's recognition of Wessex as the most efficiently operated water and
wastewater company in England and Wales. Our asset portfolio also includes an
interest in a long-term water concession in the Province of Mendoza, Argentina.
In addition, we have agreed to acquire an interest in a long-term water
concession in Cancun, Mexico. On a pro forma basis, we had 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.
 
     We are now building on our asset base by aggressively pursuing additional
concessions, outsourcing contracts and other water and wastewater projects. We
are evaluating announced privatizations, including many of the approximately 70
upcoming privatizations identified in this prospectus, as well as various
privately negotiated transactions. These potential transactions are in Europe,
the United States, Latin America, the Middle East, Africa, Asia and the Pacific
Rim.
 
     Our experienced management team consists of senior executives from Enron,
Wessex and other water and wastewater systems, and multinational companies. We
will transfer 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 will apply 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. This management team will competitively position us
to identify, evaluate, acquire, develop and finance water and wastewater
projects and services worldwide.
 
                                  OUR 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.

     FACTORS CREATING WATER BUSINESS OPPORTUNITIES. We believe that significant
business opportunities exist for private sector participation in the global
water industry. Some of the factors creating these opportunities include the
following:
 
     - Ownership of water and wastewater assets is highly concentrated in the
       public sector.
 
     - Governments and multinational agencies are promoting higher standards of
       water and wastewater quality and environmental protection.
 
     - Major capital investment and efficiency improvements are necessary to
       meet these increasing requirements, to connect growing populations to
       water and wastewater systems and to replace aging water and wastewater
       infrastructure.
 
     - Management of water resources and storage and transportation of water are
       becoming increasingly important, especially in areas where water is
       scarce.
 
     - Governments frequently face budgetary constraints and often lack the
       technical expertise to address these issues effectively.
 
     - 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.
 
     BUSINESS OPPORTUNITIES. The business opportunities for participation in the
global water industry for companies like ours include:
 
     - GOVERNMENT OUTSOURCING OF OWNERSHIP, OPERATION AND MANAGEMENT OF WATER
       AND WASTEWATER ASSETS. Following the successful trend of international
       electricity, gas and telecommunication privatizations, many governments
       are turning to the private sector to own, operate and manage their water
       and wastewater assets and services. Governments in Argentina, Chile,
       Colombia, France, Germany, Indonesia, Malaysia, Mexico, the Philippines
       and the United Kingdom have privatized water and wastewater assets. 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. Governments in Europe, the
       United States, Latin America, the Middle East, Africa, Asia and the
       Pacific Rim have announced public tenders for water and wastewater
       concessions or projects.
 
     - MUNICIPAL AND INDUSTRIAL OUTSOURCING OF WATER AND WASTEWATER RELATED
       SERVICES. We believe that municipalities 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, while retaining ownership of their assets. They will
       seek companies with the operating experience and capital necessary to
       provide reliable water supply and wastewater treatment services, to meet
       higher water quality standards, to comply with increasingly stringent
       environmental regulations and to reduce operational and financial
       uncertainty.
 
      Services provided to these municipal and industrial customers 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
 
      Industrial customers with large water supply and wastewater treatment
      requirements include the chemical, refining, pharmaceutical, high
      technology, food and beverage, paper and pulp, steel, automobile and
      energy industries.
 
     - WATER RESOURCE DEVELOPMENT AND MANAGEMENT. Increasing demand for water
       resources is focusing efforts on means of extracting, managing, storing
       and transporting water resources as efficiently as possible. Governments,
       which historically have been responsible for developing and managing
       water
 
                                        2
<PAGE>   8
 
       resources, are now seeking private sector assistance to address their
       water resource issues due to the technical, operational and financial
       expertise required to build, operate and fund these capital intensive
       projects.
 
     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 an ability to:
 
     - Obtain and demonstrate the requisite operating experience and management
       depth to qualify for bidding on international privatizations or
       concessions
 
     - Identify and evaluate transactions, including the appropriate assessment
       and mitigation of operational, political and regulatory risks
 
     - Access adequate capital at cost effective levels
 
     - Develop and manage international infrastructure projects
 
     We believe that we have the necessary skills and experience necessary to
enable us to compete successfully in the global marketplace.
 
                           OUR COMPETITIVE STRENGTHS
 
     We have several competitive strengths that should enable us to become a
leading and profitable participant in the global water industry:
 
     - EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAM. Our executives come
       from Enron, Wessex and other water and wastewater systems and
       multinational companies and bring with them extensive experience in both
       the development and the operation of infrastructure projects worldwide,
       including water and wastewater operations. Many of our executives were
       actively involved in developing and managing projects for Enron in the
       United States and around the world. 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 States and the United Kingdom.
       In addition, our management team has infrastructure development
       experience in Europe, the United States, Latin America, the Middle East,
       Africa, Asia and the Pacific Rim. They lead a group of experienced
       business developers who identify opportunities in the global water
       industry. In pursuing global water projects, we apply the extensive
       experience of our management team and business developers in evaluating
       and securing projects, acquisitions and financings.
 
     - 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
 
                                        3
<PAGE>   9
 
       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 also
       intend to consider acquisitions of privately owned water and wastewater
       assets with predictable contractual or regulated revenue streams.
 
      -- Acquiring water and wastewater assets. We intend to acquire water and
         wastewater assets through participation in public tenders and privately
         negotiated transactions throughout the world, including Europe, the
         United States, Latin America, the Middle East, Africa, Asia and the
         Pacific Rim. In evaluating potential acquisitions, we plan to follow a
         disciplined approach focused on identifying the potential for increased
         returns, analyzing future regulatory and rate case changes and
         assessing the engineering, operational, regulatory, financing,
         economic, structuring, insurance, tax, environmental, legal and
         accounting risks related to each transaction.
 
      -- Owning, operating and managing water and wastewater assets. Following
         an acquisition of water or wastewater assets, we plan to increase
         revenues by optimizing the applicable tariff structure, expanding
         customer bases and improving the accuracy and timing of billing and
         collection procedures. In addition, we intend to increase operating
         income by improving quality, extending services, reducing operating
         costs, rationalizing 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, residuals management and
       underground infrastructure remediation and development services. In
       evaluating potential services transactions, we plan to follow a
       disciplined approach similar to that used in evaluating acquisitions.
 
     - 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 there are significant capital, technical and
       operational needs in this area of the water industry and that governments
       are increasingly turning to the private sector to meet these needs.
       Although this is not currently a significant portion of our business, we
       intend to pursue opportunities in resource management as they arise.
 
     By applying our expertise in these three areas, we plan to offer the full
spectrum of services required to meet our public and private customers' water
and wastewater needs. We expect that our ability to evaluate potential
investments 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).

     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 on privatized
    utilities in the United Kingdom 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.
 
(2) Basic and diluted earnings per common share for Wessex are not meaningful on
    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.
 
WE HAVE A LIMITED OPERATING HISTORY
 
     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. We expect to experience
significant competition in bidding and negotiating for water projects. Our
limited operating history may create significant impediments to our qualifying
for bidding on some projects or, if qualified, being successful in bidding.
 
     Our consolidated revenues will be derived almost exclusively from the
operations of Wessex until such time as our other investments begin to generate
revenue. Revenue 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 SUCCESS IS 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 significant 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. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Outlook."
 
WATER AND WASTEWATER COMPANIES FACE PRICE REGULATION THAT COULD ADVERSELY AFFECT
OUR FINANCIAL RESULTS
 
     Governments generally regulate the prices that water and wastewater
companies may charge their customers. The regulatory regimes vary from country
to country and at times can give great discretion to the regulatory authority.
In the case of Wessex, the U.K. Director 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 that will be lower than current
price limits. 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. The actual rates of return
achieved by these companies can vary significantly from the projected rates of
return applied by the Director in setting prices, depending on performance.
Historically, Wessex has exceeded projected rates of return, although there can
be no assurance that it will continue to do so.
 
                                        7
<PAGE>   13
 
Although we are unable to predict the precise outcome of the current U.K. rate
review, it is likely to reduce significantly Wessex's revenues and earnings.
 
FAILURE TO ACCURATELY IDENTIFY AND ASSESS THE RISKS RELATED TO AN ACQUISITION OR
PROJECT COULD ADVERSELY AFFECT OUR OPERATING RESULTS
 
     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 substantially 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 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.
 
OUR BUSINESS REQUIRES SUBSTANTIAL CAPITAL EXPENDITURES AND WE COULD HAVE
DIFFICULTY FINANCING OUR OPERATIONS, ACQUISITIONS AND PROJECTS
 
     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, off-balance sheet financing
and equity investments. There is a risk that we may engage in significantly
leveraged transactions and that we may pledge all or substantially all of our
assets. For example, the capital stock of Wessex, our most significant
subsidiary, 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 or any other purpose.
 
LACK OF OPERATIONAL CONTROL IN CERTAIN PROJECTS COULD ADVERSELY AFFECT OUR
OPERATING RESULTS
 
     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
other stakeholders in company management. In these cases, decisions with respect
to certain significant matters 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 certain projects could materially and
adversely affect our interest in these projects and, as a result, our financial
condition and results of operations.
 
WE COULD HAVE DIFFICULTY MANAGING OUR GROWTH AND INTEGRATING ACQUISITIONS
 
     We cannot assure you that our current management, personnel and other
corporate infrastructure will be adequate to manage our growth. In addition, to
the extent the success of our strategy is contingent on
 
                                        8
<PAGE>   14
 
making acquisitions of water and wastewater assets, we cannot assure you that we
will be able to integrate such acquisitions successfully without substantial
costs, delays or other operational or financial problems.
 
ENVIRONMENTAL FACTORS AND CHANGES IN REGULATIONS COULD ADVERSELY AFFECT OUR
FINANCIAL RESULTS
 
     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, certain 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.
 
WATER SUPPLY CONTAMINATION COULD ADVERSELY AFFECT OUR BUSINESS
 
     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. 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 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
 
                                        9
<PAGE>   15
 
nationally important facilities such as water systems, could have a material
adverse effect on our financial condition and results of operations.
 
OUR OPERATING RESULTS COULD BE ADVERSELY AFFECTED BY WORK STOPPAGES AND OTHER
LABOR RELATIONS MATTERS
 
     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. 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 significant work stoppages in future years.
 
CHANGES IN CURRENCY EXCHANGE RATES AND LIMITATIONS ON REMITTANCE OF FUNDS COULD
ADVERSELY AFFECT OUR FINANCIAL RESULTS
 
     Because a significant portion of our operations will be conducted 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, which
could have a material adverse effect on our financial condition and results of
operations. Legal restrictions or shortages in currencies in certain countries
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
ADVERSELY AFFECT OUR 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 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 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
 
     Certain countries in which we may pursue opportunities do 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
 
                                       10
<PAGE>   16
 
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 RESTRICT AZURIX'S OPERATIONS
 
     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 for Azurix Europe require Wessex to meet certain 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 senior credit
facility. Additionally, covenants contained in the senior credit facility
restrict Wessex from paying dividends to Azurix except in certain circumstances.
This could limit our ability to pay dividends on our common stock.
 
     Under the senior credit facility, Enron is required to hold at least 20% of
the legal and beneficial ownership of the ordinary share capital of Azurix
Europe, and no person, directly or indirectly, may hold a greater percentage
than Enron or its significant subsidiaries. In addition, at least 50% of the
directors of Azurix Europe, or directors having at least 50% of the voting
rights in respect of Azurix Europe's board of directors, must also be directors
or senior officers of Enron or its significant subsidiaries. Therefore, if, for
example, as a result of equity offerings by Azurix or other transactions
involving Azurix, Enron's ownership of Azurix and Azurix Europe is significantly
diluted, a further sale of Azurix equity by Azurix or Atlantic Water Trust could
trigger an event of default under the senior credit facility. 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 this will be the case.
 
     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.
 
                                       11
<PAGE>   17
 
     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."
 
WE DEPEND ON CERTAIN KEY EXECUTIVES
 
     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 are not adequately replaced,
our business could be materially adversely affected. See "Management."
 
WE RELY ON ENRON FOR SERVICES
 
     We will have an agreement with Enron pursuant to which Enron provides
various corporate staff and support services to us. These include services such
as information technology, building maintenance, security and other office
services as well as certain employee-related services such as employee
development and training, and maintenance of certain 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 will participate in Enron's corporate insurance program. The agreement
will provide that we may use the international offices of Enron and its
affiliates for certain 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. The agreement will be
for an indefinite term, but it may be terminated by either party with 180 days'
notice. If the agreement is terminated, we may not be able to obtain similar
regulatory or other services on equivalent terms from third parties.
 
ENRON AND ITS AFFILIATES MAY COMPETE WITH AZURIX IN CERTAIN ACTIVITIES; AZURIX
MAY ONLY ENGAGE IN ACTIVITIES GENERALLY IDENTIFIED IN THIS PROSPECTUS,
INCIDENTAL ACTIVITIES AND OTHER ACTIVITIES AS ENRON MAY APPROVE
 
     Enron and Azurix will enter into an agreement that limits the scope of
Azurix's business and provides 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, 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.
 
     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 Enron
may approve in its sole discretion. The agreement will restrict both Enron and
Azurix from taking action to restrict each others' businesses or to subject them
to certain forms of regulation. 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."
 
                                       12
<PAGE>   18
 
ENRON'S INFLUENCE OVER US MAY CREATE 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 option is exercised in full). Each of Enron and
Marlin Water Trust, a Delaware business trust created in connection with the
formation of Atlantic 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 replace
half of the directors of Atlantic Water Trust and currently, and in certain
cases following the offering, up to half of the Azurix 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. Some
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 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, certain 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
tradable 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."
 
     Subject to certain limitations, Marlin Water Trust, or the trustee under
its senior notes indenture, may cause the sale of Atlantic Water Trust's
interest in Azurix if certain events occur unless the senior notes are repaid
from other sources. See "Principal and Selling Stockholders."
 
LACK OF A SPECIFIC USE OF PROCEEDS COULD RESULT IN AN INADEQUATE RETURN
 
     We have not designated any specific use for the net proceeds to us from
this sale of common stock, and there is a risk that we will not be able to
deploy the proceeds of the offering to obtain an adequate return on capital. We
intend to use the net proceeds primarily for general corporate purposes,
including
                                       13
<PAGE>   19
 
working capital and the expansion of our business through strategic acquisitions
as opportunities arise. Accordingly, management will have significant
flexibility in applying the net proceeds of the offering. Although part of our
business strategy is to pursue acquisitions of water and wastewater assets,
there can be no assurance that we will find strategic acquisition opportunities
at favorable prices or that we will have sufficient capital resources to finance
our acquisition strategy. See "Use of Proceeds."
 
YOU WILL INCUR SUBSTANTIAL AND IMMEDIATE 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 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. You will incur
an immediate increase in pro forma net tangible book value of $     per share
and an immediate dilution of $     per share. In addition, you will incur
additional dilution upon the exercise of outstanding stock options. See
"Dilution."
 
WE WILL NOT PAY DIVIDENDS
 
     We do not currently anticipate paying any cash dividends. See "Dividend
Policy."
 
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, certain provisions of the certificate of incorporation
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 "Cautionary
Statements Regarding 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.

           CAUTIONARY STATEMENTS REGARDING 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.

<PAGE>   21
 
                                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 for general corporate purposes, including working
capital and the expansion of our business through strategic acquisitions as
opportunities arise.
 
                                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.
 
                                       16
<PAGE>   22
 
                                    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.
Substantially 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 ("U.S. GAAP") that were derived from Wessex's
audited financial statements prepared in accordance with U.K. generally accepted
accounting principles ("U.K. GAAP").
 
     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.

- ---------------
 
(1) Equity in earnings of affiliates for all periods presented for Wessex is
    related primarily to Wessex's interest in UK Waste.
 
(2) The year ended March 31, 1998 includes a windfall tax on privatized
    utilities in the United Kingdom 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, basic earnings per
    common share and diluted earnings per common share would have been $179.0
    million, $0.78 per common share and $0.77 per common share, respectively.
 
(3) The basic and diluted earnings per share amounts for Wessex are based on the
    historical average ordinary shares of Wessex and average ordinary shares of
    Wessex plus the share effect of the potential conversion to ordinary shares
    of its dilutive securities, respectively.
 
(4) Wessex stockholders were given the option to elect dividends declared to be
    paid in cash or the issuance of additional ordinary shares. Of the dividends
    declared per share for the years ended March 31, 1995, 1996, 1997, 1998 and

          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
 
     In December 1998, Enron contributed Azurix to Atlantic Water Trust and
Atlantic Water Trust sold a 50% voting interest in Atlantic Water Trust to
Marlin Water Trust, with Enron retaining a 50% voting interest. 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, indirectly, 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 was incorporated on January 29, 1998, and as a result, its results
of operations and cash flows discussed in this prospectus are from the date of
incorporation to December 31, 1998. However, substantially all of Azurix's
results of operations and cash flows occurred during the fourth quarter of 1998,
subsequent to the Wessex acquisition.
 
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 total cost of the Wessex acquisition, including
transaction costs, was $2.4 billion, plus the assumption of $481.5 million of
existing Wessex debt. Wessex had cumulative mandatorily redeemable preference
shares outstanding when it was acquired. These were redeemed by Wessex in
December 1998.
 
SALE OF INVESTMENT IN UNCONSOLIDATED AFFILIATE
 
     On November 30, 1998, Wessex sold its interest in Wessex Waste Management
Ltd, a joint venture with Waste Management International Plc that does business
as UK Waste, for $337.9 million. 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 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.
 
RESULTS OF OPERATIONS
 
     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
 
                                       21

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.
 
     For purposes of the discussion below, the results of operations for the
periods being compared are translated using the actual average exchange rate of
the most recent period ("Constant Rate Results"), thereby eliminating the effect
of changes in currency exchange rates. Tables shown below present the condensed
results of operations and highlight the impact of changes in currency exchange
rates by displaying for the earlier period in each presentation, both the
historical results and Constant Rate Results.

</TABLE>
 
     Operating revenues increased 5.3% for the pro forma year ended December 31,
1998, as compared to the year ended March 31, 1998, as a result of the pricing
formula in the Wessex license and higher revenues due to increased sales from SC
Technology AG, Wessex's subsidiary that manufactures, sells and operates
biosolid drying equipment.
 
     Operations and maintenance expense increased by $8.9 million, or 7.9%, for
the pro forma year ended December 31, 1998, as compared to the year ended March
31, 1998, primarily due to an increase in the operating costs of SC Technology.
 
     General and administrative expense increased by $15.0 million for the pro
forma year ended December 31, 1998, as compared to the year ended March 31,
1998, primarily from Azurix corporate activities incurred during the fourth
quarter of 1998 in pursuit of acquisitions. See "-- Outlook."
 
     Depreciation and amortization increased by $23.4 million, or 36.1%, for the
pro forma year ended December 31, 1998, as compared to the year ended March 31,
1998. This increase is a result of the amortization of goodwill related to the
acquisition of Wessex, the increase in depreciation on fixed assets arising from
property additions in the capital expenditure program and the effect of the
Wessex purchase price allocation, which increased the depreciable value of the
fixed assets.
 
     Equity earnings of affiliates declined from $13.4 million in the year ended
March 31, 1998 to a loss of $0.8 million in the pro forma year ended December
31, 1998. This decrease is the result of the sale of UK Waste. The pro forma
results reflect the sale as if it occurred on January 1, 1998.
 
     Net interest expense was $8.7 million for the year ended March 31, 1998,
compared to $66.1 million for the pro forma year ended December 31, 1998. The
pro forma results assume the acquisition of Wessex occurred on January 1, 1998,
and, therefore, assume an interest charge on the debt incurred to purchase
Wessex from that date, less the proceeds from the sale of UK Waste.

     Income tax and utility tax expense of $56.5 million for the pro forma year
ended December 31, 1998 was $165.9 million lower than the year ended March 31,
1998, primarily due to a one-time utility tax levied in calendar year 1997 on
privatized utilities, which was paid in two installments, one in December 1997
and one in December 1998.
 
  AZURIX -- DATE OF INCEPTION TO DECEMBER 31, 1998
 
     Azurix was incorporated on January 29, 1998. Substantially all of its
results of operations occurred in the fourth quarter of 1998 following the
Wessex acquisition. Azurix's operating revenues, operations and maintenance
expense and depreciation and amortization expense were all substantially related
to the consolidation of the Wessex results of operations for the period after
the Wessex acquisition.
 
     Azurix's general and administrative expenses were related to Wessex's
operations and the pursuit of acquisition activities primarily during the fourth
quarter.
 
     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 64.1%. 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 (1) a valuation allowance recognized on a U.S.
deferred tax asset generated from general and administrative expense incurred in
the United States; (2) a valuation allowance recognized on a U.K. deferred tax
asset relating to non-deductible interest expense prior to achieving a
consolidated tax position; and (3) non-deductible amortization of goodwill
resulting from the acquisition of Wessex.

</TABLE>
 
     Regulated operating revenues, on an annualized basis, for the six months
ended October 2, 1998 increased 4.9% compared to the year ended March 31, 1998,
primarily as a result of the pricing formula in the Wessex license.
 
     Unregulated revenues, on an annualized basis, of $40.4 million for the six
months ended October 2, 1998 compares to $32.6 million for the year ended March
31, 1998. The primary reason for the increase is higher revenues from SC
Technology.
 
     Operating Expenses. On an annualized basis, operations and maintenance
expense increased by 10.5% for the six months ended October 2, 1998, as compared
to the year ended March 31, 1998. This increase is primarily attributable to
increased activity from SC Technology.
 
     General and administrative expense increased by 148.5% for the six months
ended October 2, 1998, on an annualized basis, when compared to the year ended
March 31, 1998. This increase is primarily attributable to the expense incurred
by Wessex directly related to its acquisition by Azurix. These expenses were
incurred prior to the consummation of the acquisition.
 
     The increase in depreciation and amortization for the six months ended
October 2, 1998, on an annualized basis, when compared to the year ended March
31, 1998, is primarily 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 13.4%, or $1.8 million, when annualized and compared to the year
ended March 31, 1998. This decrease was primarily associated with higher
operating expenses at UK Waste.
 
     Net interest expense increased in the six months ended October 2, 1998 on
an annualized basis, as compared to the year ended March 31, 1998, by 40.2% or
$3.5 million. This was primarily due to a reduction in the average cash and cash
equivalent position in the current period resulting from the payment of the
first installment of the one-time utility tax in December 1997 and the
preference share redemption and elimination in 1998.
 
     Tax expense was $165.2 million lower in the annualized six month period
ended October 2, 1998, as compared to the year ended March 31, 1998. This
decrease was primarily due to a one-time tax levied on privatized utilities in
the year ended March 31, 1998.

</TABLE>
 
     Regulated operating revenues increased 3.9% for the year ended March 31,
1998, as compared to the year ended March 31, 1997, primarily as a result of the
pricing formula in the Wessex license.
 
     Unregulated revenues of $32.3 million for the year ended March 31, 1998
were $4.0 million, or 14.1% higher than the prior year primarily due to higher
revenue from SC Technology.
 
     Operating Expenses. Operations and maintenance expense increased 4.6%
primarily due to higher operating expenses from SC Technology.
 
     General and administrative expense decreased 12.6% for the year ended March
31, 1998, as compared to the prior year, due to cost reduction measures
implemented by Wessex and costs incurred in the year ended March 31, 1997
related to an unsuccessful acquisition attempt.
 
     Depreciation and amortization increased 7.2% for the year ended March 31,
1998 as compared to the prior year primarily due to property additions resulting
from Wessex's capital expenditure program.
 
     Net interest expense was $8.6 million for the year ended March 31, 1998,
compared to net interest income of $10.5 million for the year ended March 31,
1997, primarily due to a reduction in the cash and cash equivalent position
related to the buy-back of its "B" and "C" classes of ordinary shares in
February 1997.
 
     Equity earnings of affiliates for the year ended March 31, 1998 decreased
by 12.5%, or $1.9 million, compared to the prior year. An affiliate, UK Waste,
was sold in November 1998.

     Income tax and utility tax expense was $135.0 million higher in the year
ended March 31, 1998 when compared to the prior year. This increase was
primarily due to 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 the effect of a change in the U.K. statutory tax rate from 33% to 31%.
 
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 significant business
development effort with associated general, administrative and operating
expenses. These expenses currently approximate $15 million pretax on a quarterly
basis. These expenses are in addition to the existing general, administrative
and operating expenses of Wessex. Our future financial results, therefore, will
depend significantly on the success of our acquisition and development
activities, which are difficult to predict. 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.
 
     A substantial portion of our 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 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 reduce significantly Wessex's
revenues and earnings, but should not have a material adverse effect on Azurix's
financial position.
 
     On February 2, 1999, we granted options to purchase approximately 7.8
million shares of our common stock through an employee stock option plan.
Assuming an initial public offering price of $       per share, we will incur a
non-cash expense of approximately $       million ($       million after-tax)
per year related to these options, which will be charged to income over the
average vesting period of four years.
 
     It is anticipated that we will refinance a portion of our existing debt in
April 1999 potentially resulting in a one-time non-cash charge of $
million ($       million after-tax) in the second quarter due to the write-off
of deferred financing costs and the incurrence of approximately $     million in
deferred financing costs related to the proposed new financing.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Substantially all of Azurix's cash flows for the period from January 29,
1998 to December 31, 1998 occurred in the fourth quarter, subsequent to the
Wessex acquisition. Cash flow from operations totaled $4.4 million during the
period from January 29, 1998 to December 31, 1998. Relating 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.
 
     At December 31, 1998, Azurix had a working capital deficit of $129.6
million. Of this deficit, $71.0 million represents deferred income, relating to
customer billings in advance of providing water and wastewater services, which
does not require the future use of cash. At December 31, 1998, Azurix had
available capacity, under its credit facilities described below, to provide
$91.5 million of working capital. Management believes that cash flows from
operations and the available capacity under these credit facilities is
sufficient to fund the working capital deficit.
 
                                       26
<PAGE>   32
 
     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.
 
     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 has 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, $475.5 million is
permitted, if necessary, to refinance certain borrowings discussed below and
$91.5 million is permitted, if necessary, to fund the working capital deficit
discussed above. The term loan capacity of $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. The acquisition loan notes are
redeemable, at the option of the holder, semi-annually beginning September 30,
1999, with final redemption occurring September 30, 2005. The term loan facility
requires repayment of $199.5 million by July 24, 2000 and repayment of any
remaining outstanding amount under the term loan in July 2003. The revolving
credit facility terminates in July 2003.
 
     Azurix, through Wessex, is a borrower under committed credit facilities
with six major banks that provide an aggregate $399.1 million for general
corporate purposes. As of December 31, 1998, these bank facilities were
completely drawn down by Wessex. The bank facilities mature in April 1999.
Wessex also has $24.9 million of short-term uncommitted bank borrowings that
mature in April 1999. It is anticipated that Azurix will refinance these
short-term borrowings with long-term borrowings prior to maturity. If the
proposed refinancing is not consummated prior to the maturity of the short-term
borrowings, Azurix will utilize available capacity of $475.5 million under the
senior credit facility to refinance these borrowings. In addition to the
refinancing of its short-term borrowings on a long-term basis, Azurix
anticipates such refinancing will provide borrowing capacity of approximately
$400 million. This borrowing capacity, combined with additional borrowing
capacity generated from the cash flows of specific projects acquired, will be
used by Azurix in funding acquisitions and privatizations.
 
     Azurix has contractual commitments for capital expenditures to be incurred
after December 31, 1998 of $130.2 million.
 
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. Interest rate risk is a
consequence of having variable rate debt obligations, as changing interest rates
impact the discounted value of future cash flows. Azurix utilizes swap contracts
to minimize its interest rate risk. Currency exchange rate risk is the result of
transactions that are denominated in a currency other than the functional
currency. The primary purpose of Azurix's foreign currency hedging activities is
to protect against the volatility associated with currency exchange rates. It
attempts to reduce these risks by utilizing derivative financial instruments for
non-trading purposes. Azurix's accounting policies for derivative financial
instruments are described in Note 1 to the Consolidated Financial Statements.
 
     Azurix engages in hedging programs aimed at limiting the impact of such
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.
All currency or interest rate contracts that are entered into by Azurix are
entered into for the sole purpose of hedging an existing or anticipated
exposure, not for speculation.
 
     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 adverse market movements. It is
based on volatility and correlation data provided by J.P. Morgan, Azurix's
choice of a
                                       27
<PAGE>   33
 
statistical confidence level and its estimate of the time period required to
liquidate the positions in the various financial instruments in the event of an
adverse market movement. 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 certain 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.
 
     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
 
     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.
                                       28
<PAGE>   34
 
     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.
 
     We do not have operational control of the Mendoza concession. Therefore, we
will consult with SAUR, the operator, to develop an understanding of SAUR's Year
2000 efforts at Mendoza.
 
     We have been able to conduct only a limited assessment of the Cancun
concession in which we have agreed to acquire an interest. After we complete the
Cancun acquisition, we will inventory, assess, analyze, convert and test the
Cancun systems for Year 2000 readiness. We will develop Year 2000 contingency
plans to minimize Year 2000 problems that have not manifested themselves or have
not been corrected by January 1, 2000. We plan to conduct a further assessment
during April 1999.
 
     In formulating and implementing the Enron plan, we expect to engage
independent consultants, technicians and other external resources for purposes
that may include verification and validation of certain of our mission-critical
facilities and functions. These consultants may participate in various aspects
of the plan, including the inventory, assessment and testing phases, as well as
the development of contingency planning.
 
     We do not yet know enough about our Year 2000 problems to be able to
estimate the exact amount of time required to remediate our Year 2000 problems.
As we progress further in the plan, we will be able to better estimate the time
required for remediation, testing, validation and contingency planning.
 
  Costs to Address Year 2000 Issues
 
     As of March 15, 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.
 
                                       29
<PAGE>   35
 
     We will rely on Enron for services that involve computer processing. 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.
 
     Azurix is not able to estimate the full extent of Year 2000 readiness of
the systems located at the Mendoza and Cancun concessions at this time. However,
we intend to evaluate the Year 2000 readiness of these systems before the end of
April 1999.
 
     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 certain
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.
 
     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
 
     - 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 certain 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
 
     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 ("BOO") or
       build-own-transfer ("BOT") project. In both a BOO and a BOT, the private
       party builds, owns and operates the asset. In the case of a BOT, the
       private party then transfers the asset back to the government after a
       fixed term, usually 15 to 25 years but often longer. The BOO or BOT
       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.
 
                                       32
<PAGE>   38
 
     - 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 ("O&M") 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 -- United States."
 
     - 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 certain selected water and wastewater
privatizations in Europe, the United States, 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, BOTs or leases, except in
the United States, where private parties have primarily entered into O&M
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 O&M contracts
represents aggregated fees over the term of the contract. The estimated size for
BOTs 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. Azurix
estimates that the global water industry has total annual revenues of
approximately $300 billion. In addition, the World Bank and other sources have
estimated that over $600 billion will be spent on worldwide water and wastewater
infrastructure over the next decade. We believe that much of that capital will
come from the private sector.
 
     Enron, one of the world's leading integrated natural gas and electricity
companies, formed Azurix in 1998 to pursue opportunities in the global water
industry. Our first significant step was to acquire Wessex, a water and
wastewater company based in southwestern England, for $2.4 billion in order to
give us the operating experience necessary to compete successfully for business
around the world. Wessex's operating expertise is evidenced by the industry
regulator's recognition of Wessex as the most efficiently operated water and
wastewater company in England and Wales. Our asset portfolio also includes an
interest in a long-term water concession in the Province of Mendoza, Argentina.
In addition, we have agreed to acquire an interest in a long-term water
concession in Cancun, Mexico. On a pro forma basis, we had 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.
 
     We are now building on our asset base by aggressively pursuing additional
concessions, outsourcing contracts and other water and wastewater projects. We
are evaluating announced privatizations, including many of the approximately 70
upcoming privatizations identified in this prospectus, as well as various
privately negotiated transactions. These potential transactions are in Europe,
the United States, Latin America, the Middle East, Africa, Asia and the Pacific
Rim.
 
     Our experienced management team consists of senior executives from Enron,
Wessex and other water supply and wastewater systems, and multinational
companies. We will transfer 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 will apply 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. This management team will
competitively position us to identify, evaluate, acquire, develop and finance
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.
 
     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 (1) increasingly
stringent standards for water quality, wastewater services and environmental
protection, (2) the need to provide growing urban populations with safe drinking
water supply and wastewater treatment systems and (3) 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
 
                                       35
<PAGE>   41
 
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 BOT or BOO
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.

     UNITED STATES. 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 $140 billion for
       water 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 BOT 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.

  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. Industry
sources report that approximately 40% of U.S. municipal water and wastewater
systems currently outsource some of their operations to the private sector. We
expect that outsourcing by U.S. municipalities will increase for several
reasons. 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 significant 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 significant
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 industry sources, the fees associated with providing contract
operations and consulting, design, engineering and management 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
                                       41
<PAGE>   47
 
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 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.
 
     In the United States, in excess of five million dry tons of biosolids are
produced annually, and approximately 55% is recycled. Industry experts
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. Industry sources
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 $140 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 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. Industry sources have
estimated that the underground water and wastewater infrastructure market for
the municipal market alone in the United States currently has annual revenues of
approximately $6.4 billion, and this market is expected to continue to 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,
 
                                       42
<PAGE>   48
 
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 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 major competitors
in the international water market. These two companies are significantly larger
than the next group of international competitors. These smaller competitors
include privatized water and wastewater companies from the United Kingdom and
some smaller French and Spanish companies. Some construction companies also bid
on water and wastewater projects, more often on BOT 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, certain 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.
 
OUR COMPETITIVE STRENGTHS
 
     We have several competitive strengths that should enable us to become a
leading and profitable participant in the global water industry.
 
  EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAM
 
     Our executives come from Enron, Wessex and other water and wastewater
systems and multinational companies and bring with them extensive experience in
both the development and the operation of infrastructure projects worldwide,
including water and wastewater operations. Many of our executives were actively
involved in developing and managing 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
                                       43
<PAGE>   49
 
capitalization of approximately $25 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 States and the United
Kingdom. In addition, our management team has infrastructure development
experience in Europe, the United States, Latin America, the Middle East, Africa,
Asia and the Pacific Rim. They lead a group of experienced business developers
who identify opportunities in the global water industry. In pursuing global
water projects, we apply the extensive experience of our management team and
business developers in evaluating and securing projects, acquisitions and
financings.
 
     Our management team will build upon its extensive experience and knowledge
from Enron, other water systems and other multinational companies to provide us
with the necessary skills to compete effectively in the global water industry.
Through its subsidiaries, Enron is actively involved in the development,
acquisition, financing, promotion and operation of natural gas and power
projects worldwide. Azurix management has the proven 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
 
     - 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 April 1998, the water industry regulator for England and Wales rated
Wessex the most efficient of the privatized water and wastewater companies.
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.
                                       44
<PAGE>   50
 
     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 the second highest operating margins 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. Our executives understand how the regulatory
framework and the privatization process work in the countries where they may
have previously pursued infrastructure projects. In these countries, the same
political leadership with whom they have previously worked may make decisions
regarding water and wastewater privatizations. In many cases, the regulatory
framework and sometimes complex pricing regimes are the same as those in the gas
or electricity industries with which our management has experience. This
understanding of the regulatory framework and pricing regime allows us to
understand better how we can optimize value through tariff management and
deliver a better service to our customers.
 
  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 a wide array of
capital market instruments and innovative off-balance sheet financing
structures, as well as attracting and leveraging private equity. 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 that have appreciated in
value. 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 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, the United States, 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 significant 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.
 
     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
                                       46
<PAGE>   52
 
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 optimizing 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 revenues. For example, we might expand the number of customers
connected, while optimizing 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 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
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. Finally, we will
optimize tariffs by applying our experience in managing regulated assets and
providing better service.
 
     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
 
     - 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.
                                       47
<PAGE>   53
 
     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 in certain municipalities. 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 certain services to
full privatization of their systems. Working with municipal clients will also
allow us to understand local markets and identify attractive systems for
acquisition.
 
  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 BOT projects for long-distance pipelines, aqueducts
and reservoirs in the Middle East and another project to extract water in Latin
America. Although this is not currently a significant portion of our business,
we intend to pursue opportunities in water resource development and management
as they arise.
 
EXISTING AZURIX ASSETS
 
  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 April 1998, the Office of Water Services ("Ofwat"), the
industry regulator for England and Wales, published its assessment of relative
operating efficiency, which showed Wessex as the most efficient 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 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, where two 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,
 
                                       48
<PAGE>   54
 
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 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 turnover 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 advanced treatment at Wessex's
thermal biodrier at its major wastewater treatment facility at Avonmouth, near
Bristol. Wessex is currently installing 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
membrane technology,
 
                                       49
<PAGE>   55
 
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 technology to
produce a high quality effluent 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 trade effluent. The charging
basis for bulk supplies in some cases provides for annual recalculation by
reference to the expenditure associated with the supply. Trade effluent from
industrial users is normally charged on a formula basis taking account of the
volume of effluent, its strength and costs of removal and treatment.
 
                                       50
<PAGE>   56
 
     In March 1998, the U.K. government issued new proposals for water charging.
These proposals include:
 
     - Permitting those who currently pay for water on an unmeasured basis and
       use water only for essential domestic purposes to continue to do so in
       their present home
 
     - Eliminating the threat of disconnection for domestic customers
 
     - Providing domestic customers the choice of a meter, free of charge, if it
       suits their needs
 
     - Providing assistance to customers with special needs
 
     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.
 
     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 closed loop 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. Mendoza is one of Argentina's fastest growing provinces. Enron has
contributed to Azurix its 32.1% interest in OSM. SAUR owns a 32.1% interest in
OSM, 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%. Although SAUR is the operator, certain decisions regarding OSM require
the approval of both Azurix and SAUR.
 
     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. 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.
 
                                       51
<PAGE>   57
 
     The concession holder is charged with operating, maintaining and upgrading
OSM's ten drinking water plants, 17 wastewater treatment plants as well as
associated distribution and collection networks to Mendoza. OSM serves over one
million water customers and has 285,000 water connections. OSM provides
wastewater services to 883,000 people and has 210,000 wastewater connections.
The concession contract requires OSM to expand the water and wastewater
connections in concession area over the next 10 to 15 years. OSM'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. OSM 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.
 
     OSM is required to meet standards of service established by the special
purpose regulatory body known as Ente Provincial de Agua y Saneamiento ("EPAS")
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 annual report that will specify, among other things, the company's
progress with respect to its plan of operation and expansion.
 
     OSM must pay the Province a yearly royalty based on operating revenue. This
royalty is equal to 3.85% in the first five years of the concession and 9.98%
thereafter.
 
     The concession may be terminated for fault of the concession holder under
certain circumstances, including: repeated failure to provide service as
required by the concession contract; repeated violation of applicable EPAS
regulations; unjustified delays in completion of the then-current plan of
operation and expansion; willful withholding of information from EPAS; failure
to maintain adequate performance bonds; and any change in the corporate
structure of OSM 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 that event of a termination for public interest reasons,
the Province must compensate OSM for its lost investment. OSM believes it is in
compliance with the concession contract in all material respects.
 
  CANCUN, MEXICO
 
     We have entered into an agreement to acquire a 49.9% economic interest in
and 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.
("DHC") is the concessionaire that holds the concession. Affiliates of one of
the current shareholders, Grupo Mexicano de Desarrollo, S.A. ("GMD"), will
retain an aggregate 50.1% economic interest in DHC. We will pay the sellers
$13.5 million in cash for our 49.9% interest. We will also lend DHC up to $25
million to permit DHC to retire certain indebtedness and to initiate certain
improvements in the wastewater treatment system. The first funds for the loan
were advanced in February 1999, and we will purchase the equity interest on
receipt of certain governmental approvals to the investment, expected in March
1999.
 
     The concession was initially granted to DHC on the condition that it would
invest a specified amount of capital in projects to provide services under the
concession. As a result of the devaluation of the Mexican peso in 1994, DHC 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
to operate the concession. In February 1997, GMD and DHC agreed with the state
government that, as a condition to reassuming operation of and retaining the
concession, DHC would make the necessary investments and form an association
with an experienced operator of water concessions.
 
     The concession extends to October 2023. Based on figures available at the
date of acquisition, the concessionaire serves a population of approximately
350,000 through 67,000 connections. An estimated
                                       52
<PAGE>   58
 
70% of the concession's revenues are derived from the supply of drinking water
to tourist hotels, whose revenues are primarily U.S. dollar based. The water
tariff paid by the hotels is adjusted quarterly 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 revenues come
from residential drinking water supply and from wastewater services. Residential
drinking water rates are adjusted 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.
 
     FONATUR, the Mexican tourism board, currently owns three wastewater
treatment plants that process 72% of wastewater from the hotel zone and the
Cancun urban zones. We intend to pursue investment or ownership opportunities in
all three of these facilities. The remaining 28% of wastewater is treated by
DHC.
 
     We will have three seats on the board of directors of DHC, while the 50.1%
shareholders will have two. We will have the right to appoint the chief
executive officer, the chief financial officer and the chief operating officer
of DHC. GMD will appoint the chairman of DHC's board and the non-voting board
secretary. Resolutions concerning certain corporate actions and governance
issues will require supermajority approval.
 
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 key suppliers provide energy (representing
approximately 10% of operational costs), pipes and infrastructure goods. The
majority of Wessex's energy requirements are supplied by three companies. Terms
with strategic suppliers are negotiated to derive the best overall terms
incorporating continuity of supply and payment terms.
 
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 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 of wastewater biosolids using the
Swiss Combi thermal 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. 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. As of
February 28, 1999, SC Technology had approximately 50 employees.

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 of Azurix's less than wholly owned
subsidiaries, to the extent of Azurix's interest in the subsidiary. 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.

                               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, 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 law
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. In certain cases, 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 rates
of return achieved by individual companies can vary significantly from the
projected rates of return
 
                                       55
<PAGE>   61
 
assumed by the Director in setting prices. Historically, Wessex has exceeded
these rates of return, although there can be no assurance it will continue to do
so.
 
     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 effluent into sewers.
Contamination caused by effluent 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. Monopolies and Mergers 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 certain
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 Water Services' license continues until 2014 and is subject to
renewal. 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 is being 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 will strengthen the financial
independence of Wessex Water Services' regulated business, providing of water
supply and wastewater services, by imposing 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 and a requirement to maintain an
investment grade rating for corporate debt of Wessex Water Services.
 
     The license as modified will also require a dividend policy to be agreed
with the Director that ensures that Wessex Water Services retains sufficient
funds to finance its core activities and will require 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 to 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 certain
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
                                       56
<PAGE>   62
 
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 the new price
adjustment factor, the Director will make an allowance for the investment needed
to meet new quality and environmental obligations.
 
     The Director estimated, 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 estimates 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. Each company is
to draw up a business plan for submission to the Director in April 1999. In July
1999, the Director will publish his draft determination of new price limits to
run from 2000 to 2005, and his final decisions will be made in November 1999. If
companies disagree with the Director's price determination, they may challenge
his decision by requesting a reference to the Monopolies and Mergers Commission.
Although we are unable to predict the precise outcome of the current U.K. rate
review, it is likely to reduce significantly Wessex's revenues and earnings, but
should not 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
                                       57
<PAGE>   63
 
ensure that regulated companies are able to finance the carrying out of their
functions; that there should be consumer representative bodies to promote
consumer interests; that a clearer link should be made between the prices
utilities can charge and the customer service standards they achieve; that full
information should be available on companies' performance on customer service
standards and on the links between this performance and the remuneration of
directors; and that 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 certain
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 EU
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 courses. 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
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 ("MOP") 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 MOP and in a special purpose
regulatory body known as EPAS. Decisions of EPAS may be reviewed by the Minister
of MOP and the Governor of the Province.
 
  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 MOP 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 MOP, 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 OSM 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 OSM will receive
 
                                       59
<PAGE>   65
 
the same level of revenue as under the prior regime, thus allowing OSM 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. OSM may request adjustments to the new tariff if (1) the
new tariff lowers consumption significantly, (2) OSM 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, or (3) OSM 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 MOP, which has adopted laws respecting water quality. Like most provinces in
Argentina, the MOP issues permits and regulates discharges of pollutants into
water bodies. In addition, OSM 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 OSM.
 
     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 ("CNA"), 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 CNA for use of water rights. The
Cancun/Isla Mujeres concession is regulated by Concession Integral de los
Servicos de Agua Potable, Alcantarillado Sanitario y Saneamiento ("CAPA"), an
agency of the State of Quintana Roo. One of the requirements of the concession
is that the concessionaire achieve and maintain a 95%
 
                                       60
<PAGE>   66
 
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 DHC has good relations with the state's governor
elect.
 
  TARIFF RATES
 
     The tariff rates are set by CAPA and are based on the principal 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 DHC 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, DHC 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 is still obligated to approve them.
 
     Under the terms of the concession amendments, the concessionaire is
permitted to disconnect a customer for non-payment.
 
  ENVIRONMENTAL MATTERS
 
     DHC 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.
 
     The wastewater plants operated by DHC 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 DHC is 70 mg/l of total suspended solids and
biochemical oxygen demand. With the completion of the plants 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.
Compliance with these regulations will likely be a significant aspect of our
operations.

  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 substantial 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 certain 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.
 
  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
 
                                       62
<PAGE>   68
 
     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. In certain cases, 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.
 
     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.

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
accountants and our internal accounting staff with respect to accounting and
audit procedures. The Audit Committee will also review, with management and our
independent auditors, our annual financial statements, the adequacy of our
internal accounting and control procedures and policies and related matters. The
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
1986, as amended. The Compensation Committee will be responsible for making
decisions with respect to the compensation of our executive officers and key
executives. The Board of Directors has established the Stock Plan Committee to
administer our stock plan. Rebecca P. Mark, Kenneth L. Lay and Jeffrey K.
Skilling currently serve on the Stock Plan Committee. The Board of Directors
may, from time to time, establish other committees of the Board of Directors.

annual incentive plan with a bonus target of 100% of his annual base salary. If
Mr. Kulpecz is 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 certain performance objectives, Mr. Kulpecz will be entitled
to a payment so that the value of the equity in Enron and Azurix which he has
received pursuant to his employment agreement plus the payment equals one
million dollars. The agreement prohibits Mr. Kulpecz from competing with Azurix
until the later of September 14, 2001 or one year following termination of
employment. The agreement also contains other customary benefits and
perquisites.
 
     Colin F. Skellett entered into an employment agreement with Wessex, which
entitles Mr. Skellett to an annual salary of $423,300. The employment agreement
may be terminated by either Wessex or Mr. Skellett upon 12 months' notice. The
agreement otherwise terminates on 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
 
                                       68
<PAGE>   74
 
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.
 
STOCK OPTION GRANTS
 
     On February 2, 1999, Azurix issued options to purchase shares of common
stock at $16.72 per share to the Named Executive Officers. Rebecca P. Mark
received 2,000,000 options which will vest 25% per year over a four-year period.
Rodney L. Gray received 1,000,000 options which will vest 20% per year over a
five-year period. Amanda K. Martin received 1,000,000 options which will vest
25% per year over a four-year period. Alex Kulpecz received 1,000,000 options
which will vest 20% per year over a five-year period. Colin F. Skellett received
600,000 options which will vest 33 1/3% per year over a three-year period. In
addition, on February 2, 1999, Azurix issued an aggregate of 2,199,850 options
to purchase shares of common stock at $16.72 per share for other employees with
vesting schedules ranging from three to five years. All of these options expire
ten years after the grant date.

                              CERTAIN TRANSACTIONS
 
AGREEMENT REGARDING BUSINESS OPPORTUNITIES AND RELATED MATTERS
 
     Enron and Azurix will enter into an agreement that addresses the scope of
Azurix's business and provides 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, 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's pursuing activities competitive with
Azurix, provided Enron has followed the rules just described.
 
     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 Enron
may approve in its sole discretion. The agreement will restrict both Enron and
Azurix from taking action to restrict each others' businesses or to subject them
to certain forms of regulation.
 
     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. Disputes under the agreement are to
be resolved through arbitration. The agreement also permits conflicts of
interest between Enron and Azurix to be resolved through approval by a majority
of the directors of Azurix not associated with Enron.
 
SERVICES AGREEMENT WITH ENRON
 
     We will have an agreement with Enron pursuant to which Enron provides
various corporate staff and support services to us. These include services such
as information technology, building maintenance, security and other office
services as well as certain employee-related services such as employee
development and training and maintenance of certain 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 will participate in Enron's corporate insurance program. The agreement
will provide that we may utilize the international offices of Enron and its
affiliates for certain projects. This is subject to our mutual agreement with
Enron or its affiliates on a project-by-project basis. Our agreement will
provide that we will reimburse Enron for the direct charges related to the Enron
services which we use. We will also be allocated and be liable to Enron for an
amount of overhead charges related to Enron corporate staff and support services
which we utilize. The agreement will be for an indefinite term, but it may be
terminated by either party with 180 days' notice.
 
UNDERTAKINGS
 
     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.
 
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 option is exercised in full). Each of Enron and Marlin Water
                                       70
<PAGE>   76
 
Trust owns a 50% voting interest in Atlantic Water Trust. To date, Enron has
appointed all the directors of Atlantic Water Trust and Azurix, although Marlin
Water Trust at any time has the right to replace half of the directors of
Atlantic Water Trust and currently, and in certain cases following the offering,
up to half of the Azurix 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.
 
     Some 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 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, certain 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."
 
REGISTRATION RIGHTS AGREEMENT
 
     We will enter into an agreement with Atlantic Water Trust to provide
Atlantic Water Trust with certain registration rights relating to the shares of
our common stock. The registration rights agreement will provide that Atlantic
Water Trust may request registration under the Securities Act of all or any
portion of Azurix shares covered by the registration rights agreement, and
Azurix will be obligated to register such shares as requested by Atlantic Water
Trust. Atlantic Water Trust will also have the right to include shares of our
common stock held by it in other registrations of common equity securities of
Azurix initiated by Azurix on its own behalf or on behalf of its other
stockholders. The rights of Atlantic Water Trust under the registration rights
agreement will be transferable by Atlantic Water Trust. See "Risk
Factors -- Marlin Water Trust May Cause Atlantic Water Trust to Sell Azurix
Stock."
 
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. Either Enron or Azurix may terminate the license at
any time, whereupon Azurix must cease using the phrase and the logo within 90
days, except for existing supplies of materials. Enron may terminate the license
earlier, however, only on account of Azurix's failure to cure a violation of the
agreement following notice of default or if the percentage of Enron's or
Atlantic Water Trust's ownership of Azurix falls below 35%. The license is
royalty free.

ATLANTIC WATER TRUST
 
     In December 1998, Enron contributed Azurix to Atlantic Water Trust, a
Delaware business trust. Marlin Water Trust acquired 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 trust certificates and senior notes, that mature December 15, 2001, for
a total of $1.149 billion. Marlin Water Trust used the proceeds from the
issuance of the senior notes and the trust certificates to purchase a beneficial
interest in Atlantic Water Trust. Currently, five institutional investors and
their affiliates hold the trust certificates of Marlin Water Trust.
 
     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 will have the right to appoint
such members, but Marlin Water Trust will have 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.
 
     Subject to certain limitations, Marlin Water Trust, or the trustee under
its senior notes indenture, may cause the sale of Atlantic Water Trust's
interest in Azurix if certain events occur unless the senior notes are repaid
from other sources. Such 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 March 12,
1999 was $68.88.

<PAGE>   79
 
                          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 is a summary of certain provisions of our certificate of
incorporation and bylaws. Our certificate of incorporation and bylaws have been
filed as exhibits to this registration statement, and you should read the
certificate of incorporation and bylaws for any terms that may be important to
you.
 
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.
 
CERTAIN ANTI-TAKEOVER AND OTHER PROVISIONS OF OUR CERTIFICATE OF INCORPORATION
AND BYLAWS
 
     In addition to our board of directors' right to issue preferred stock, our
certificate of incorporation and bylaws contain certain provisions that could
make a hostile takeover difficult.
 
  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
 
                                       74
<PAGE>   80
 
voting power of the outstanding shares of common stock must vote for removal. In
general, after the Trigger Date the board of directors, not the stockholders,
will have the right to appoint persons to fill vacancies on the board of
directors.
 
  NO 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. Special
meetings of the stockholders may be called only by the board of directors.
 
  BUSINESS COMBINATIONS UNDER DELAWARE LAW
 
     We are subject to Section 203 of the Delaware General Corporation Law.
Section 203 generally 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. Atlantic Water Trust and
Enron are not subject to the restrictions of Section 203. 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.
 
  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 (1) 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, and (2)
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 certain 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.
 
  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 (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
violation of laws, (3) under Section 174 of the Delaware General Corporation Law
or (4) 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.

                          DESCRIPTION OF INDEBTEDNESS
 
INDEBTEDNESS OF AZURIX EUROPE LTD.
 
  SENIOR CREDIT FACILITY
 
     Azurix Europe, an indirect, wholly owned subsidiary of Azurix and the
holding company for Wessex, has a senior credit facility with a group of banks.
The 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 senior credit facility consists of a term loan facility
of L194 ($322.6) million and a revolving credit facility of L346 ($575.3)
million. Amounts outstanding under the senior credit facility bear interest at a
rate based on the London interbank offered rate. As of February 28, 1999, L127
($211.2) million in principal was outstanding under the term loan facility and
L5 ($8.3) million in principal was outstanding under the revolving credit
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 ($99.8) million outstanding at any time.
 
     Azurix Europe is required to repay L120 ($199.5) 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 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. Subject to certain exceptions, 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
senior credit facility will sell, transfer, grant or lease or otherwise dispose
of all or any part of its assets. Certain 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. Subject to
certain exceptions, no borrower under the senior credit facility will enter into
any amalgamation, demerger, merger or reconstruction. Subject to certain
exceptions, 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 no default under the 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 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 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 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, among others, is an event of default
under the 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
 
                                       77
<PAGE>   83
 
     - Azurix Europe failing to comply with certain of its covenants, or a
       borrower not complying with any provision of a finance document or a

     - A cross-default related to any financial indebtedness of Azurix Europe or
       its subsidiaries occurring, subject to certain exceptions, including when
       the aggregate amount of financial indebtedness is less than L15 ($24.9)
       million
 
     - Certain events of insolvency or bankruptcy of a borrower or a material
       subsidiary occurring
 
     - Subject to certain exceptions, any attachment, or execution affecting any
       assets of a borrower or a material subsidiary having an aggregate value
       of L15 ($24.9) 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

       exceptions
 
     - 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
 
  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 ($117.2) million to
Wessex shareholders in lieu of cash consideration for the ordinary shares of
Wessex. The acquisition loan notes are redeemable, at the option of the holder,
semi-annually beginning September 30, 1999, with final redemption occurring
September 30, 2005. Interest on the acquisition loan notes accrues at the London
interbank offered rate and is payable semi-annually. 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.
 
  SENIOR LOAN AGREEMENT -- AFFILIATE NOTE
 
     Bristol Water Trust entered into a L73 ($121.4) million senior loan
agreement with Azurix Europe in December 1998. Bristol Water Trust is a wholly
owned subsidiary of Atlantic Water Trust. The interest rate on this loan is
6.25% per annum payable semi-annually. Repayment of this loan is due three
business days prior to December 15, 2001.
 
                                       78
<PAGE>   84
 
     CERTAIN COVENANTS. In addition to agreeing to provide Bristol Water Trust

     - Sell, transfer or otherwise dispose or cease to control the ordinary
       shares of Wessex Water Ltd.
 
     - Make any substantial change to the general nature or scope of its
       business as a water and wastewater company in the U.K.
 
     - Declare, recommend, make or pay any dividend, distribution or payment to

       payable by it within three business days after notice of non-payment
 
     - Azurix Europe failing to comply with its covenants or a representation,
       warranty or statement made by it being materially incorrect and not
       remedied within 28 days
 
     - The debt under the senior secured credit facility or any replacement

     - Wessex's license being revoked or surrendered or ceasing to be held by
       Wessex Water Ltd, a wholly owned subsidiary of Wessex Water Ltd or Azurix
       Europe, subject to certain exceptions
 
     - Wessex's license or the rights or obligations under the license being
       materially modified in any manner that, in the reasonable opinion of
       Bristol Water Trust has a material adverse effect on Azurix Europe
 
     - Any person other than Wessex Water Ltd or one of its subsidiaries being
       authorized to be a water or wastewater company in the area covered by
       Wessex's license such that there would be a material adverse effect on
       Azurix Europe
 
     If a default occurs, Bristol Water Trust will have the right, by notice to
Azurix Europe at least three business days following the occurrence of the event
of default, to accelerate the payment of all outstanding principal and interest
under this loan agreement. If during this three business day period Bristol
Water Trust receives a cash offer to purchase the outstanding note in an amount
at least equal to the outstanding principal balance plus all accrued and unpaid
interest, then Bristol Water Trust will not be able to accelerate payment and
must accept the cash offer.
 
INDEBTEDNESS OF WESSEX
 
     Wessex and Wessex Water Services are borrowers under bank facilities with
six major banks that provide an aggregate of approximately L240 ($399.1) million
of availability for general corporate purposes. As of February 28, 1999, L240
($399.1) million was outstanding under these bank facilities. These bank
 
                                       79
<PAGE>   85
 
facilities mature in April 1999 and accrue interest at the LIBOR rate plus a
specified margin. In addition, as of February 28, 1999, L37.5 ($62.4) million
was outstanding under uncommitted credit facilities.
 
     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 February 28, 1999 of L41.3 million
($68.7 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 ($18.8
million) fixed rate loan repayable in ten semi-annual installments through June
2002. Wessex guarantees the obligations of Wessex Water Services under these
facilities.
 
     Wessex Water Services is the lessee under a finance lease agreement
pursuant to which L66 ($109.7) million of capital lease obligations (excluding
interest on such obligations) were outstanding as of February 28, 1999. Fixed
rate interest is included in the periodic rental payments to the lessor.
Payments are made in installments payable semi-annually through September 2002.
The lessor under this finance lease has a lien on the property that has been
acquired in connection with the leases.
 
     Each of Wessex's outstanding financing agreements contain certain
restrictive covenants, including among other things, limitations on borrowings
and the maintenance of financial ratios, such as interest coverage, net worth
and debt to equity and undertakings to perform or refrain from undertaking
certain acts. The financing agreements include standard events of default,
including non-payment, cross-defaults, insolvency, status of Wessex Water
Services as a subsidiary of Wessex and loss of Wessex's license as a water and
wastewater company.
 
     Wessex Water Services intends to launch an offering of L300 ($498.8)
million in 10-year bonds through its wholly owned subsidiary, Wessex Water
Services Finance Plc. Wessex Water Services anticipates issuing the bonds in
April 1999. The bonds will bear interest payable annually on the anniversary of
their issue at a rate to be determined taking into account market conditions at
the time of issue. All principal will be due on the tenth anniversary of the
issue date. Wessex Water Services intends to use the proceeds of the sale of the
bonds for refinancing existing indebtedness and for general corporate purposes.
 
     Bondholders will 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
 
     - Certain 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 certain events of
insolvency.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to the offering, there has been no public market for our common
stock. 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.
 
     After the offering,           shares of common stock will be outstanding.
Of these shares, the           shares to be sold in the offering will be freely
tradable 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. The remaining           shares of common stock outstanding 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 or any applicable exemption under the Securities Act. In connection
with the offering, Azurix and the selling stockholder have agreed, with certain
exceptions, not to directly or indirectly (1) 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 or (2) 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, without
the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated
on behalf of the underwriters for a period of 180 days after the date of this
prospectus. 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."
 
     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) 1% of the number of shares of common stock then outstanding, which will
equal approximately           shares immediately after the offering or (2) 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. Under Rule 144(k), a person who is
not deemed to have been an affiliate of Azurix 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 except
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.
 
     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."

                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 is for general information only and 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
 
                                       82
<PAGE>   88
 
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
 
                                       83
<PAGE>   89
 
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 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.

                                  UNDERWRITING
 
GENERAL
 
     We intend to offer our common stock in the United States and Canada through
a number of U.S. underwriters and elsewhere through international managers.
Merrill Lynch, Pierce, Fenner & Smith Incorporated,           ,           and
          are acting as U.S. representatives of each of the U.S. underwriters
named below. Subject to the terms and conditions set forth in a U.S. purchase
agreement among Azurix, the selling stockholder, Enron and the U.S.

     Azurix, the selling stockholder and Enron have also entered into an
international purchase agreement with certain international managers outside the
United States and Canada for whom Merrill Lynch International,           ,
          and           are acting as lead managers. Subject to the terms and
conditions set forth in the international purchase agreement, and concurrently
with the sale of           shares of common stock to the U.S. underwriters
pursuant to the U.S. purchase agreement, Azurix and the selling stockholder have
agreed to sell to the international managers, and the international managers
severally 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 several U.S. underwriters and the several international managers,
respectively, have agreed, subject to the terms and conditions set forth in
those agreements, to purchase all of the shares of common stock being sold under
the terms of each such agreement if any of the shares of common stock being sold
under the terms of that agreement are purchased. In the event of a default by an
underwriter, the U.S. purchase agreement and the international purchase
agreement provide that, in certain circumstances, the purchase commitments of
nondefaulting underwriters may be increased or the purchase agreements may be
terminated. The closings with respect to the sale of shares of common stock to
be purchased by the U.S. underwriters and the international managers are
conditioned upon one another.
 
     Azurix and Enron have agreed to indemnify the U.S. underwriters and the
international managers against certain liabilities, including certain
liabilities under the Securities Act, or to contribute to payments which 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 several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and certain
other conditions. The underwriters reserve the right to withdraw, cancel or
modify such 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 common stock
to the public at the 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 change.
 
     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 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 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,
without the prior written consent of Merrill Lynch on behalf of the underwriters
for a period of 180 days after the date of this prospectus, not to directly or
indirectly:
 
     - 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
 
NEW YORK STOCK EXCHANGE LISTING
 
     Azurix is applying to list the common stock on the New York Stock Exchange
under the symbol "AZX."
 
     Before these offerings, 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 U.S. representatives and the
lead managers. 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 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 the common stock or that the common stock will
trade in the public market subsequent to these offerings at or above the initial
public offering price.
 
PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS
 
     Until the distribution of the common stock is completed, rules of the SEC
may limit the ability of the underwriters and certain 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.
 
                                       87
<PAGE>   93
 
     If the underwriters create a short position in our common stock in
connection with these offerings, 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 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.
 
     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
 
     Certain 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

the country of purchase in addition to the offering price set forth on the cover
page hereof.

are being passed upon for Azurix by Vinson & Elkins L.L.P., Houston, Texas.
Certain legal matters will be passed upon for the U.S. underwriters and the
international managers by Andrews & Kurth LLP, Houston, Texas.

                   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 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
potential investment in a water concession for the city of Cancun, Mexico.
 
     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 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 potential investment in a water concession for the city of Cancun,
Mexico.
 
     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 record the historical results of Wessex for the period during 1998
prior to the Wessex Acquisition.
 
     (b) To record the historical general and administrative expense of Wessex,
excluding $20.7 million of costs incurred by Wessex prior to the Wessex
Acquisition, but directly related to the Wessex Acquisition.
 
     (c) To record depreciation of tangible assets and amortization of goodwill
acquired in the Wessex Acquisition for the period during 1998 prior to the
Wessex Acquisition. The amount of depreciation and amortization recorded was
based on a preliminary purchase price allocation. Goodwill is being amortized
over 40 years.
 
     (d) To record the following:
 
          (1) Historical interest expense of Wessex for the period during 1998
     prior to the Wessex Acquisition of $9.4 million;
 
          (2) Interest expense of $41.8 million for the period during 1998 prior
     to the Wessex Acquisition on funds borrowed to fund the Wessex Acquisition
     and to redeem the Wessex preference shares, less funds received from the
     sale of its interest in Wessex Waste Management Ltd, a joint venture with
     Waste Management International Plc, that were used to reduce such
     borrowings.
 
     (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

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

                   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. In addition, Azurix accrues revenue for the
estimated amount of water sold but not billed as of the balance sheet date.
 
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
 
                                      F-11
<PAGE>   106
                                  AZURIX CORP.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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:

Infrastructure..............................................    115

</TABLE>
 
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.
 
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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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 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 operate 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:

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
on short-term bank borrowings 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-

     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 semi-annual installments through June 2002.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 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
maturities. Judgment is necessarily required in interpreting market data and the
use of different market assumptions or estimation methodologies may affect the
estimated fair value amounts. The comparison of estimated fair value and
carrying amount are as follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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. Due to
restrictions on the use of such loss carryforwards the benefits have not been
reflected in Azurix's results of operations. 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.

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
 
                                      F-20

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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 cost 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:

Sheet.
 
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.

</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 -- EVENT SUBSEQUENT TO THE DATE OF REPORT OF INDEPENDENT PUBLIC
ACCOUNTANTS (UNAUDITED)
 
     In March 1999, Azurix filed a registration statement with the Securities

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:

                             (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

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 semi-annual 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:

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
CERTAIN RISKS AND CONCENTRATIONS
 
     Wessex's cash equivalents consist primarily of short-term money market
deposits. Wessex has deposited its cash equivalents with reputable financial
institutions and believes the risk of loss to be remote. Wessex has accounts
receivable from customers concentrated in southwestern England with no single
customer accounting for more than 10% of sales.
 
     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).

redesignated as authorized ordinary shares of 60p each.
 
ACCUMULATED OTHER COMPREHENSIVE INCOME
 
     Other comprehensive income at March 31, 1998 comprises the foreign currency
translation reserve of $178.8 million and unrealized gains on available-for-sale
securities of $3.2 million. The majority of the foreign currency translation
reserve is generated by the translation of the GBP functional currency financial
statements into the USD reporting currency.
 
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

option plan, based on save-as-you-earn contracts, under which options were
granted between August 1991 and August 1997 at prices between L1.47 and L3.58

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
was pursuant to resolutions passed by its stockholders on July 29, 1998 and
November 23, 1998 to cancel the preference shares by repaying capital to the
preference stockholders.

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.

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.

</TABLE>
 
     Azurix, the selling stockholder and Enron have also entered into a U.S.
purchase agreement with certain U.S. underwriters in the United States and
Canada for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated,           ,
          and           are acting as U.S. representatives. Subject to the terms
and conditions set forth in the U.S. purchase agreement, and concurrently with
the sale of           shares of common stock to the international managers
pursuant to the international purchase agreement, Azurix and the selling
stockholder have agreed to sell to the U.S. underwriters, and each of the U.S.
underwriters severally and not jointly has 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 international purchase agreement
and the U.S. purchase agreement.
 
     In the international purchase agreement and the U.S. purchase agreement,
the several international managers and the several U.S. underwriters,
respectively, have agreed, subject to the terms and conditions set forth in
those agreements, to purchase all of the shares of common stock being sold under
the terms of each such agreement if any of the shares of common stock being sold
under the terms of that agreement are purchased. In the event of a default by an
underwriter, the international purchase agreement and the U.S. purchase
agreement provide that, in certain circumstances, the purchase commitments of
nondefaulting underwriters may be increased or the purchase agreements may be
terminated. The closings with respect to the sale of shares of common stock to
be purchased by the international managers and the U.S. underwriters are
conditioned upon one another.
 
     Azurix and Enron have agreed to indemnify the international managers and
the U.S. underwriters against certain liabilities, including certain liabilities
under the Securities Act, or to contribute to payments which 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 several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and certain
other conditions. The underwriters reserve the right to withdraw, cancel or
modify such offers and to reject orders in whole or in part.
<PAGE>   148
 
COMMISSIONS AND DISCOUNTS
 
     The lead managers have advised Azurix and the selling stockholder that the
international managers propose initially to offer the shares of common stock to
the public at the 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 change.
 
     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.

     The expenses of these offerings, exclusive of underwriting discounts, are
estimated at $          and are payable by Azurix and the selling stockholder.
 
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.
 
     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
<PAGE>   149
 
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,
without the prior written consent of Merrill Lynch on behalf of the underwriters
for a period of 180 days after the date of this prospectus, not to directly or
indirectly:
 
     - 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
 
NEW YORK STOCK EXCHANGE LISTING
 
     Azurix is applying to list the common stock on the New York Stock Exchange
under the symbol "AZX."
 
     Before these offerings, 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 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 these offerings at or above
the initial public offering price.
 
PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS
 
     Until the distribution of the common stock is completed, rules of the SEC
may limit the ability of the underwriters and certain 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 these offerings, 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 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.
<PAGE>   150
 
     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
 
     Certain 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.

     Certain legal matters in connection with the common stock offered hereby
are being passed upon for Azurix by Vinson & Elkins L.L.P., Houston, Texas.
Certain legal matters will be passed upon for the international managers and the
U.S. underwriters by Andrews & Kurth LLP, Houston, Texas.

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

Azurix or its stockholders, (2) for acts or omissions not in good faith or which
involve intentional misconduct or knowing violations of law, (3) under Section
174 of the DGCL or (4) for any transaction from which a director derived an
improper personal benefit.

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES
 
     (a) Exhibits. See the Exhibit Index following the signature pages to this
Registration Statement.
 
     (b) Financial Statement Schedule. See Report of Independent Public
Accountants included herein on Page S-1 and Schedule I -- Condensed Financial
Information of Registrant included herein beginning on Page S-2.
 
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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                        ON FINANCIAL STATEMENT SCHEDULE
 
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. The
schedule listed in Item 16(b) is the responsibility of Azurix Corp.'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 required to be set forth therein in
relation to the basic financial statements taken as a whole.

Condition B: Charges

Part I. Explanatory Provisions

1.    Introduction

      The purposes of this Condition are set out in the following
      sub-paragraphs.

1.1   To limit increases in standard charges made by the Appointee for the
      supply of water, the provision of sewerage services and the reception,
      treatment and disposal of trade effluent. The weighted average increase is
      limited to the sum of the movement in the Retail Prices Index and an
      Adjustment Factor, called K.

      Changes in metered charges are calculated by reference to actual
      consumption in a Weighting Year (a financial year of the Appointee).
      Changes in unmetered charges are calculated by reference to caanges in
      average revenue per chargeable supply calculated on the customer base as
      at the preceding 1st December. Changes are weighted in proportion to the
      contribution which each type of charge makes to total revenue in the
      Weighting Year.

      These matters are dealt with in Part II under the heading "Restriction of
      Standard Charges for Basket Items".

1.2   To provide for a review of the Appointed Business to be carried out by the
      Director at 5 or 10 yearly intervals so that the Director can determine
      whether the Adjustment Factor should he changed. Except as expressly
      provided in this Condition all reviews will cover periods of ten
      consecutive years. This is dealt with in Part III under the heading
      "Periodic Reviews".

1.3   To enable the Appointee:

      (1) to refer to the Director for determination at 5 yearly intervals the
          question whether the Adjustment Factor should be changed;

      (2) to refer to the Director for determination from time to time the
          question or changing the Adjustment Factor to allow for Notified Items
          and Relevant Changes of Circumstance;


                                       11

<PAGE>   22


      (3) to refer to the Director for determination at any time the question of
          changing the Adjustment Factor where circumstances have a substantial
          adverse effect on the Appointed Business; and

      (4) where notice to terminate either or both of the Appointments has been
          given, to refer to the Director for determination the question what
          the Adjustment Factor should be in the future, on the assumption that
          the relevant Appointment or, as the case may be, the Appointments were
          to continue in force, for the purpose of facilitating consideration of
          the terms on which a new appointee could accept transfers of property,
          rights and liabilities from the Appointee, as provided in section
          12(4).

      These matters are dealt with in part IV under the heading "Interim
      Determinations".

1.4   To provide for the Director to initiate changes to the Adjustment Factor
      to allow for Notified Items and Relevant Changes of Circumstance. This is
      also dealt with in Part IV.

1.5   To enable the Appointee to require the Director to refer to the Monopolies
      Commission matters arising out of determinations by the Director referred
      to in sub-paragraphs 1.2 and 1.4 and references referred to in
      sub-paragraph 1.3. These matters are dealt with in Part V under the
      heading "References to the Monopolies Commission and Modification of this
      Condition".

1.6   To require the Appointee to give Information to the Director to enable him
      to make determinations under this Condition. This is dealt with in Part VI
      under the heading "Provision of Information to the Director".

2.    Defined terms which apply for the purposes of all Parts of this Condition

      any Charging Year (beginning with the Charging Year starting on 1st April
      1990) when expressed as a percentage does not exceed the Charges Limit.

4.2   The Charges Limit is the percentage calculated as RPI + K, where

           RPI is the percentage change (expressed, in the case of an increase,
           as a positive number, in the case of a decrease, as a negative number
           and, in the case of no change, as zero) in the Retail Prices Index
           between that published for the month of November in the Prior Year
           and that published for the immediately preceding November

           K is the Adjustment Factor.

4.3   The Adjustment Factor is:

      (1)  for each Charging Year starting on 1st April in the year specified in
           Column (1) of the table below, the number set opposite that Charging
           Year in Column (2) of the said table (or such other number, which may
           be a positive or negative number or zero, as shall from time to time
           be determined under this Condition):

      subsequent Charging Year gall only be increased by virtue of sub-paragraph
      4.4 to the extent that such deficiency is not attributable to any Charging
      Year ended three or more years previously.

5.    Matters Affecting the Charies Limit and the calculation of the Weighted
      Average Charges Increase

5.1   Where the Appointee determines:

      (1)  to make a material change (other than one which relates solely to the
           amount of a charge) to the basis on which it makes or calculates any
           Standard Charge, or Standard Charges taken as a whole, (other than
           Excluded Charges) for the supply of water or the provision or
           sewerage services or the reception, treatment and disposal of trade
           effluent;


                                       20

<PAGE>   31

           or consent as is referred to in the definition of "Standard Charges"
           (insofar as such change relates to charges, other than Excluded
           Charges, for the supply of water or the provision of sewerage
           services or the reception, treatment and disposal of trade effluent);
           or

      (3)  to change the basis on which the Appointee treats supplies of water
           or provisions of sewerage services as separate supplies or provisions

           Charges) which affects the calculation of Average Charge Per
           Chargeable Supply

                of "Standard Charges" as at the commencement of that Charging
                Year which are not Excluded Charges (and for this purpose where
                the Appointee proposes to charge different prices per cubic
                metre of water supplied depending upon the volume of water

           (b)  in determining, in carrying out the most recent Periodic Review
                and making any subsequent Interim Determination (or, where there
                has been no periodic Review, in making any Interim
                Determination), whether the Adjustment Factor should be changed
                (and if so what change should be made to the Adjustment Factor)

           is different from the amount of Relevant Grants in respect of that
           item which the Secretary of State, or, as the case may be, the
           Director, notified the Water Authority or, as the case may be, the
           Appointee was the amount which it had been assumed, for the purpose
           of allowing for the item as aforesaid, would be received by the
           Appointee in respect of that item.

           For the purposes of this sub-paragraph (4):

           (i)  where the Director has notified an amount in the circumstances
                described above, for which, in the circumstances described
                above, the Secretary of State or the Director has previously
                notified an amount then the amount last notified by the Director
                in the circumstances described above shall be relevant for the
                purposes or this sub-paragraph (4) to the exclusion of any
                amount previously so notified by the Secretary of State or the
                Director; and

           (ii) "Relevant Grants" means any grant or state aid made or granted
                by any governmental authority or agency of the United Kingdom or
                by the Council, Commission or other authority or agency of the
                European Communities;

           AND WHICH, in the case of a Relevant Change of Circumstance falling
           within sub-paragraphs (1) to (3), takes effect, or, in the case of a
           Relevant Change of Circumstance falling within sub-paragraph (4),
           becomes apparent, after the later of the transfer date and the
           determination, in carrying out the most recent Periodic Review, of

      whether the Adjustment Factor should be changed (and if so what change
      should be made to the Adjustment Factor), but so that where the Appointee
      requires the Director to make a reference to the Monopolies Commission in
      either or the cases referred to in sub-paragraphs 16(1) and 16(3) this
      provision shall not apply so as to exclude from the definition of a
      Relevant Change of Circumstance any matter falling within sub-paragraphs
      (1) to (4) above which took effect, or, as the case may be, became
      apparent, after the Director made such reference to the Monopolies
      Commission;

      (5)  either of the following circumstances for any Charging Year in
           respect of which the Secretary of State, or, as the case may be, the
           Director, notified the Water Authority or, as the case may be, the
           Appointee that variations in value received or expected to be
           received from Relevant Disposals of Land shall constitute a Relevant
           Change of Circumstance:

           (a)  where for any Charging Year the value received or expected to be
                received from a Relevant Disposal of any Identified Land is, or
                is expected to be, different from the value which the Secretary
                of State, or, as the case may be, the Director, notified the
                Water Authority or, as the case may be, the Appointee was the
                value attributable to a Relevant Disposal of that Identified
                Land for that Charging Year which had been allowed for in
                determining the Adjustment Factor or whether the Adjustment
                Factor should be changed (and if so what change should be made
                to the Adjustment Factor); or

           (b)  where for any Charging Year, and to the extent not taken into
                account under (a) above, the aggregate value received or
                expected to be received from Relevant Disposals of
                Non-identified Land is, or is expected to be, different from the
                value which the Secretary of State, or, as the case may be, the
                Director, notified the Water Authority or, as the case may be,
                the Appointee was the value attributable to Relevant Disposals
                of Non-identified Land for that Charging Year which had been
                allowed for in determining the Adjustment Factor or whether the
                Adjustment Factor


                                       31

                should be changed (and if so what change should be made to the
                Adjustment Factor)

           and so that any notification by the Director for the purposes of this
           sub-paragraph (5) shall be relevant for the purposes of this
           sub-paragraph (5) to the exclusion of any earlier notification by the
           Secretary of State or the Director for the purposes of this
           sub-paragraph (5) to the extent that the first-mentioned notification
           is made in respect of matters in respect of which that earlier
           notification was made.

           For the purposes of this sub-paragraph (5):

           (i)   "Identitied Land" means any piece or parcel or protected land
                 identified in any such notification referred to in (a) above as
                 is relevant for the time being for the purposes of this
                 sub-paragraph (5) as being included in that notification, not
                 being, or being part of, a piece or parcel of land which has
                 previously been the subject of a transfer under paragraph 7 of
                 Condition K;

           (ii)  "land" includes any interest or right in or over land;

           (iii) "Non-identified Land" means any piece or parcel of protected
                 land, not being, or being part of:

                 (A)  a piece or parcel of protected land identified in any such
                      notification referred to in (a) above as is relevant for
                      the time being for the purposes of this sub-paragraph (5);
                      or

                 (B)  a piece or parcel of protected land which has previously
                      been the subject of a transfer under paragraph 7 of
                      Condition K:

           (iv)  "protected land" and "disposal" have the meanings respectively 
                 given to them in section 189,

                  Appointee and any transfer under paragraph 7 of Condition K;

           (vi)   a "Relevant Disposal of Land" means and includes a Relevant
                  Disposal or Identified Land and a Relevant Disposal of
                  Non-identified Land;

           (vii)  "value" includes value of any kind including, without
                  limitation, cash, the value of real or personal property or
                  any interest in such property, the value of any right or
                  benefit (actual or prospective) and the value of any release;
                  in whole or in part, of any obligation or claim provided that
                  to the extent that any property, right or benefit shall
                  consist of a right to receive cash or any other asset then no
                  value shall be attributed to that property, right or benefit
                  but the cash or other asset the subject thereof shall be
                  included and treated as value received or expected to be
                  received in the Charging Year in which it is received or
                  expected to be received;

           (viii) references to "value received or expected to be received"
                  shall be construed so as to include receipts by, and grants
                  to, the Appointee, any Associated Company or any other
                  business in which either the Appointee or any Associated
                  Company has a material direct or indirect interest;

           (ix)   for the purpose of computing "value received or expected to be
                  received" in respect of a Relevant Disposal of Land which
                  consists of a transfer made under paragraph 7 of Condition K
                  the "value received or expected to be received" shall be the
                  value for which that transfer is made under that paragraph 7,
                  but so that where that value includes a right to receive cash
                  or any other asset then, for the purpose of this
                  sub-paragraph, no value shall be attributed to that right but:
                  the cash or other asset the subject thereof shall be included
                  and treated as value received or expected to be received in
                  the Charging Year in which it is received or expected to be
                  received;

           (x)   in the case of a right or benefit, but subject to the proviso
                 to (vii) above, value shall be deemed to have been received at
                 the dme the right is granted or the benefit arises;

      (6)  where:

           (a)  in determining the Adjustment Factor or in determining, in
                carrying out the most recent Periodic Review and making any
                subsequent Interim Determination (or, where there has been no
                Periodic Review, in making any Interim Determination), whether
                the Adjustment Factor should be changed (and if so what change
                should be made to the Adjustment Factor) an amount has been
                allowed for on account of capital expenditure to be incurred by
                the Appointee; and

           (b)  for the Charging Year last ended before the making of the
                relevant reference under paragraph 14, or, as the case may be,
                the giving of the relevant notice under paragraph 15, the
                Notified Index is at a different level from that which the
                Secretary of State, or, as the case may be, the Director,
                notified the Water Authority or, as the case way be, the
                Appointee was the level which it had been assumed would pertain
                in that same Charging Year, being a Charging Year in which it
                was assumed for the purpose of assessing the amount allowed for
                as aforesaid that capital expenditure would be incurred by the
                Appointee, provided that:

           (i)  where, in respect of an amount being allowed for on account of
                capital expenditure in the circumstances described in (a) above,
                the Director has notified a level for a Charging Year in the
                circumstances described in (b) above, for which, in respect of
                an amount being allowed for on account of that same capital
                expenditure in the circumstances described in (a) above, the
                Secretary of State or the Director has

<PAGE>   45


                previously notified a level m the circumstances described in (b)
                above, then the level last notified by the Director in respect
                of that amount being allowed for as aforesaid shall be relevant
                for the purposes of this sub-paragraph (6) to the exclusion of
                any level previously so notified for that Charging Year by the
                Secretary of State or the Director in respect of that amount
                being allowed for as aforesaid; and

           (ii) where the Appointee has made a reference under paragraph 14, or,
                as the case may be, a notice has been given under paragraph 15,
                in respect of such a difference as is mentioned in (b) above in
                respect of any charging Year but no change to the Adjustment
                Factor is made in respect of the Relevant Changes of
                Circumstance and Notified Items the subject of that reference
                or, as the case may be, that notice by reason that the answer to
                the question set out in sub-paragraph 14.2(7) in respect thereof
                is negative, then nothing in this sub-paragraph (6) shall
                prevent the Appointee from subsequently making a reference under
                paragraph 14, or the Director from giving a notice under
                paragraph 15, in respect of that same difference and in such a
                case references in b,) above to the Charging Year last ended
                before the making of the relevant reference or, as the case may
                be, the giving of the relevant notice shall be to the Charging
                Year last ended before the making of the first reference or, as
                the case may be, the giving of the first notice in respect of
                that difference.

For the purposes of this sub-paragraph (6) and sub-paragraph 14.2:

(A)   "the Notified Index" means such index of national construction costs
      notified by the Secretary of State, or, as the case may be, the Director,
      to the Water Authority or, as the case may be, the Appointee as the
      Secretary of State, or, as the case may be, the


                                       35

<PAGE>   46


      Director, considers appropriate and reasonable for the purposes of this
      Condition as being the index which is to apply for the purposes of the
      relevant Charging Year

(B)   where:

      (x)  the Notified Index is not available by 1st September in any year:

      (y)  there is a material change to the basis of compiling the Notified
           Index; or

      (z)  the level of the Notified Index is revised after the determination of
           the questions in respect of a Relevant Change of Circumstance falling
           within this sub-paragraph (6)

      then the question as to how changes in construction costs in the relevant
      Charging Year should be allowed for as a Relevant Change or Circumstance
      shall be determined by the Director in such manner as the Director, after
      prior consultation with the Appointee, determines to be appropriate and
      this Condition shall be modified accordingly; and

(C)   "the indexed Capital Costs Amount" is the amount found by multiplying A by
      B, where

      A is the aggregate amount of capital expenditure which, for the purpose of
      assessing the amount allowed for as described in (a) above, it was assumed
      would be incurred by the Appointee in the relevant Charging Year

      B is the percentage difference between the level of the Notified Index for
      the relevant Charging Year and the level notified for that same Charging
      Year by the Secretary of State, or, as the case may be, the Director, as
      described in (b) above;

(7)   where, in determining the Adjustment Factor or in determining, in carrying
      out the most recent Periodic Review and making any


                                       36

<PAGE>   47


      subsequent Interim Determination (or where there has been no Periodic
      Review, in making any Interim Determination), whether the Adjustment
      Factor should be changed (and if so what change should be made to the
      Adjustment Factor) an amount has been allowed for:

(a)   on account of steps taken or to be taken for the purpose of securing or
      facilitating compliance with a legal requirement (not being one m respect
      of which an amount has been allowed for as described under (b) below) or
      achieving a service standard adopted or to be adopted by the Appointee; or

(b)   on account of making a change which the Water Authority or the Appointee
      has determined to make for any such purpose as is referred to in
      sub-paragraph (2) of this definition (a "Relevant Change of Circumstance")

AND

(i)   in any such case as is described in (a) above the Appointee has not taken
      (by the date by which it was assumed for the purposes of assessing the
      amount allowed for as aforesaid it would take those steps) any or all of
      those steps which, for the purpose of assessing the amount allowed for as
      aforesaid, it was assumed it would take; and

      (A)  as a result, the amount allowed for as aforesaid is substantially
           greater than the costs (if any) actually incurred by the Appointee
           for the relevant purpose specified in (a) above; and

      (B)  that purpose has not been otherwise achieved; or

(ii)  in any such case as is described in (b) above, either:

      (A)  the Appointee has not done (by the date by which it was assumed for
           the purposes of assessing the


                                       37

<PAGE>   48


           amount allowed for as aforesaid it would do those things) any or all
           of the things to make that change which, for the purpose of assessing
           the amount allowed for as aforesaid, it was assumed it would do; and

           (x)  as a result, the amount allowed for as aforesaid is
                substantially greater than the costs (if any) actually incurred
                by the Appointee on account of complying with the same legal
                requirement for the purposes of compliance with which the
                Appointee had determined to make the change on account of which
                that amount was allowed for as aforesaid; and

           (y)  the change which the Water Authority or the Appointee determined
                to make, on account of which that amount was allowed for as
                aforesaid, has not been made to the extent assumed; or

      (B)  for reasons which are or would be outside the control of a prudently
           managed and efficient company holding the Appointments there has
           been, or will be, a substantial change in the costs required to be
           incurred in order to make that change; and

(8)   where, for reasons which are or would be outside the control of a
      prudently managed and efficient company holding the Appointments, the
      costs required to be incurred:

      (a)  in order to secure or facilitate compliance with a legal requirement;
           or

      (b)  to achieve a service standard adopted or to be adopted by the
           Appointee


                                       38

<PAGE>   49


           are substantially different from the costs (if any) which it was
           assumed:

           (i)   in determining the Adjustment Factor; or
 
           (ii)  in determining, in carrying out the most recent Periodic Review
                 and making any subsequent Interim Determination (or, where
                 there has been no Periodic Review, in making any Interim
                 Determination), whether the Adjustment Factor should be changed
                 (and if so what change should be made to the Adjustment Factor)

           were or would be required to be incurred for that purpose to
           the extent that such difference:

           (A)   has not been taken into account as a Relevant Change of
                 Circumstance falling within sub-paragraph (6) of this
                 definition; and

           (B)   is not attributable to any such assumption having been based on
                 any estimate or other Information furnished by the Water
                 Authority or, as the case may be, the Appointee which the Water
                 Authority or, as the case may be, the Appointee knew, or which,
                 by reference to the circumstances which were known or ought
                 reasonably to have been known to the Water Authority or, as the
                 case may be, the Appointee at the time when that estimate or
                 other Information was furnished, the Water Authority or, as the
                 case may be, the Appointee should reasonably have known, was
                 materially inaccurate;

a "Relevant Item" is any of the following:

      (1)  a Relevant Change of Circumstance (other than a Relevant Change of
           Circumstance falling within sub-paragraph (5) of the definition);

      (2)  a Notified Item; and

      (3)  a Relevant Disposal of Land

           and references to a Relevant Item are to a Relevant Change of
           Circumstance (other than a Relevant Change of Circumstance falling
           within sub-paragraph (5) of the definition), a Notified Item or a
           Relevant Disposal of Land as the context may require.

13.2  In the definition of a "Relevant Change of Circumstance" and for the
      purpose of that definition:

      (1)  a "legal requirement" is any of the following:

           (a)  any enactment or subordinate legislation to the extent that it
                applies to the Appointee in its capacity as a water undertaker
                or sewerage undertaker (and for this purpose, but without
                prejudice to the generality of the foregoing, "subordinate
                legislation" includes any order made under section 20 and any
                authorisation granted, approval given, or prohibition imposed,
                by the Secretary of State under The Water Supply (Water Quality)
                Regulations 1989):

           (b)  any regulation made by the Council or the Commission of the
                European Communities to the extent that it applies to the
                Appointee in its capacity as a water undertaker or sewerage
                undertaker, or decision taken by the said Commission which is
                binding on the Appointee in its capacity as a water undertaker
                or sewerage undertaker and to the extent that it is so binding;

           (c)  any licence, consent or authorisation given or to be given by
                the Secretary of State, the Authority or other body or competent
                jurisdiction to the Appointee for the purpose of carrying on any
                or the functions of a water undertaker or sewerage undertaker;

           (d)  any undertaking given by the Appointee to, and accepted by, the
                Secretary of State or, as the case may be, the Director for the
                purposes of section 20(5)(b);

           (e)  other than any such undertaking as is referred to in (d), any
                undertaking given by the Appointee to any enforcement authority,


                                       40

           and accepted by that enforcement authority, to take all such steps:

           (i)  as are specified by that enforcement authority to be necessary
                or appropriate for the Appointee to take for the purpose of
                securing or facilitating compliance with any legal requirement
                in relation to which that enforcement authority is the
                enforcement authority: or

           (ii) the taking of which is specified by that enforcement authority
                to be a condition or requirement of granting or renewing any
                such license, consent or authorization as is referred to in (c)
                or agreeing not to withdraw the same;

      (f)  the Conditions of these Appointments; and

      (g)  any interpretation of law, or finding, contained in any judgment
           given by a court of tribunal of competent jurisdiction in respect of
           which the period for making an appeal has expired which requires any
           legal requirement failing within (a) to (f) above to have effect in a
           way:

           (i)  different to that in which it previously had effect; or

           (ii) different to that in which it was taken to have effect:

                (A)  for the purpose of determining the Adjustment Factor;
                     or, as the case may be,

                (B)  in determining whether the Adjustment Factor should be
                     changed (and if so what change should be made to the
                     Adjustment Factor)

      but so that nothing in sub-paragraphs (a) to (g) above shall apply so as
      to include:

           (i)  any such legal requirement as is referred to in section 113 
                or 129; or


                                       41

<PAGE>   52


           (ii) those sections

      to the extent in either case that they require the Appointee to pay fees
      or charges to the relevant enforcement authority; and

(2)   "enforcement authority" means any person or body having jurisdiction to
      enforce or to take action under or in respect of the relevant legal
      requirement.

13.3  in paragraph 14 and in the definition of a "Relevant Change of
      Circumstance":

      (1)  references to costs include references to expenditure and loss or
           revenue and references to costs being incurred include references to
           expenditure being made and loss of revenue being suffered; and

      (2)  references to receipts include references to receipts, cash or other
           assets of any sort, whether of a capital or revenue nature and
           including receipts of grants, contributions, gifts and loans.

3.4   For the purpose of section 15(5)(b), the provisions of this Condition, to
      the extent that they relate to a Relevant Change of Circumstance falling
      within sub-paragraph (5) of that definition, are provisions of the
      Appointments which cannot be modified. This sub-paragraph shall cease to
      have effect if, but only if, this Condition ceases to contain any
      provision relating to changes to the Adjustment Factor to allow for
      Notified Items and Relevant Changes or Circumstance.

14.   References to the Director relating to Notified Treats and Relevant
      Charges of Circumstance and circumstances having a substantial adverse
      effect on the Appointed Business

14.1  The Appointee may from time to time refer to the Director for
      determination by him having considered the proposals of the Appointee) the
      questions set out in sub-paragraph 14.2 or, as the case may be,
      sub-paragraph 14.3. Such reference shall be made by notice given to the
      Director, which, in the case of the questions set out in sub-paragraph
      14.2, shall be given in accordance with sub-paragraph 14.4. For the
      purposes of sub-paragraph 14.2 a single reference may be made in respect
      of any number or Notified Items and Relevant Changes of Circumstance and
      sub-paragraph 14.2 shall be construed accordingly.


                                       42

<PAGE>   53


14.2  In the case of a Notified Item or where there has been or is to be a
      Relevant Change of Circumstance all of the following:

      (1)  what are, or are likely to be, the costs, receipts and savings
           reasonably attributable to the Relevant Item and also, in the case of
           a Relevant Change of Circumstance falling within sub-paragraph (5) of
           the definition, the costs, receipts and savings reasonably connected
           with the Relevant Disposal of Land. For this purpose the costs
           reasonably attributable to a Relevant Change of Circumstance falling
           within sub-paragraph (6) of the definition shall be taken to be equal
           to the indexed Capital Costs Amount;

      (2)  except in the case of a Relevant Change of Circumstance falling
           within sub-paragraph (5) of the definition, to what extent:

           (a)  are the costs determined under (1) reasonably recoverable
                through charges for services provided, functions carried out by,
                and other activities of, the Appointee in its capacity as a
                water undertaker or sewerage undertaker which are not Standard
                Charges for Basket Items (not being Excluded Charges);

           (b)  in the case or receipts and savings, is the Relevant Item
                relevant to services provided, functions carried out by, and
                other activities of, the Appointee as a water undertaker or
                sewerage undertaker which are not Basket Items in respect of
                which the Appointee makes Standard Charges (not being Excluded
                Charges)

           and where it is determined that such costs are reasonably recoverable
           as aforesaid or, as the case may be, that the Relevant Item is
           relevant as aforesaid, either in full or to an extent, then
           references hereafter to costs, receipts and savings reasonably
           attributable to a Relevant Item are to those costs, receipts and
           savings except to that extent;

      (3)  both of the following:

           (a)  what costs reasonably attributable to, or connected with, the
                Relevant Item as determined under (1) and what timing of
                incurring of such costs are appropriate and reasonable for the


                                       43

<PAGE>   54


                Appointee in all the circumstances to incur and programme, or,
                as the case may be, to have incurred and programmed, by reason
                of the Relevant Item; and

           (b)  what receipts and savings reasonably attributable to, or
                connected with, the Relevant Item as determined under (1) and
                what timing of such receipts and savings is appropriate and
                reasonable for the Appointee in all the circumstances to achieve
                and programme or, as the case may be, to have achieved and
                programmed, by reason of the Relevant Item

           and for the purpose of determining the separate amounts under (a) and
           (b), but without prejudice to the generality of the foregoing:

                (i)  no account shall be taken of:

                (A)  any trivial amounts;
                (B)  any costs, to the extent that they would have been, or
                     would be, avoided by prudent management action taken since
                     the transfer date (and for this purpose what constitutes
                     "prudent management action" shall be assessed by reference
                     to the circumstances which were known or which ought
                     reasonably to have been known to the Appointee at the
                     relevant time);
                (C)  any savings achieved by management action taken since the
                     transfer date over and above those which would have been
                     achieved by prudent management action (and for this purpose
                     what constitutes "prudent management action" shall be
                     assessed by reference to the circumstances at the relevant
                     time); or
                (D)  any amounts attributable to matters allowed for in
                     determining the Adjustment Factor or in determining, in
                     carrying out the most recent Periodic Review and making any
                     subsequent Interim Determination (or, where there has been
                     no Periodic Review, in making any Interim Determination),
                     whether the Adjustment Factor should be changed (and if so
                     what change should be made to the Adjustment Factor),
                     except to


                                       44

<PAGE>   55


                     the extent that such amounts otherwise fall to be taken
                     into account as amounts reasonably attributable to, or
                     connected with, the Relevant Item under this sub-paragraph
                     (3) and sub-paragraph (1) by virtue of the definition of a
                     Notified Item and a Relevant Change or Circumstance; and

           (ii) in the case of a Relevant Change of Circumstance falling within
                sub-paragraph (2) of the definition, regard shall be had to the
                desirability of obtaining information from metering trials and
                to any information available to the Director or the Appointee
                from metering trials as well as to the fact that the prohibition
                on charging by ratable value contained in section 80 applies to
                charges in respect or services provided after, but not before,
                the end of 31st March 2000;

      (4)  having determined under (3) the separate amounts of costs and or
           receipts and savings in respect of each Relevant Item, what are the
           annual cash flows thereof (costs being netted off against the amount
           of receipts and savings for this purpose) over each Charging Year
           included in the timing determined under (3) (those annual cash flows
           being hereinafter referred to as "the Base Cash Flows");

      (5)  what is the annual aggregate of:

           (a)  one half of the Base Cash Flows in respect of Relevant Changes
                of Circumstance falling within sub-paragraph (5) of that
                definition; and

           (b)  the Base Cash Flows in respect of all other Relevant Changes of
                Circumstance and Notified Items

      in both cases the subject of the notice or notices under subparagraph
      14.4 or paragraph 15;

      (6)  what is the Net Present Value or the amounts determined under (5)
           calculated up to the start of the first of the Charging Years for
           which the next Periodic Review falls to be carried out (having regard
           to any


                                       45

<PAGE>   56

                Review Notice or Reference Notice which has been given at the
                time when the reference is made) and what is the aggregate of
                those Net Present Values ("the Materiality Amount");

      (7)  is the Materiality Amount equal to or does it exceed ten per cent of
           the turnover attributable to the Appointed Business in the latest
           financial year for which accounting statements have been prepared and
           delivered to the Director under Condition F, as shown by those
           accounting statements, and for this purpose where the Materiality
           Amount is a negative figure it shall be treated as though it were a
           positive figure:

      (8)  if so, what is the Net Present Value or the aggregate Base Cash Flows
           determined under (5) calculated up to the latest date in the timing
           determined under (3) ("the Allowable Amount"); and

      (9)  what change, if any, to the Adjustment Factor over the period until
           the first of the Charging Years for which the next Periodic Review
           under paragraph 9 falls, or would (but for any Review Notice or
           Reference Notice which has been given at the time when the reference
           is made) fall, to be carried out ("the Relevant Period"), not being
           or including a change to the Adjustment Factor applying in respect of
           the Charging Year starting on 1st April 1990, is most likely to
           allow, or, as the case may be, require, the Appointee to make such
           charges, whether over the Relevant Period or otherwise, ("Adjusted
           Charges") as are likely to ensure that the effect of the Allowable
           Amount on its financial position and performance over the Relevant
           Period will, so far as reasonably practicable, be the Same as if the
           Allowable Amount had been allowed for in determining the Adjustment
           Factor or, as the case may be, in determining, in carrying out the
           most recent Periodic Review, whether the Adjustment Factor should be
           changed.

           For the purpose of determining what that effect should be it shall be
           assumed that the Allowable Amount would have been allowed for in that
           determination in such a manner as to secure:

           (a)  that the Net Present Value of the change in revenue attributable
                to the making of Adjusted Charges would be equal to the
                Allowable Amount; and


                                       46

<PAGE>   57


      (b)  that the timing of the effect on revenue attributable to the making
           of Adjusted Charges over the Relevant Period would be such that taken
           as a whole, Key Indicators would be appropriate to the financial
           position and performance which investors and creditors would
           reasonably expect of a properly managed company holding the
           Appointments, whose sole business consists of being a water
           undertaker and a sewerage undertaker and, without excluding other
           considerations which may also be relevant, having its equity share
           capital listed on The International Stock Exchange of the United
           Kingdom and the Republic of Ireland Limited

      but so that:

      (i)  the appropriateness of Key Indicators shall be assessed by reference
           to the financial position and performance which investors and
           creditors would reasonably expect at the time at which the relevant
           Interim Determination is made; and

      (ii) where costs have been allowed for in determining the Allowable Amount
           it shall be further assumed, where the relevant Interim Determination
           is made within five years of the transfer date, that those costs will
           be financed other than by the proceeds of an issue of equity share
           capital.

14.3  Both of the following:

      (1)  whether any circumstance which has a substantial adverse effect on
           the Appointed Business or on its assets, liabilities, financial
           position, or profits or losses, has occurred, not being one which
           would have been avoided by prudent management action taken since the
           transfer date; and

      (2)  if so, what change should be made to the Adjustment Factor.

      For this purpose what constitutes "prudent management action" shall be
      assessed by reference to the circumstances which were known or which ought
      reasonably to have been known to the Appointee at the relevant time.

14.4  A Reference Notice given to the Director in respect of sub-paragraph 14.2
      shall contain or be accompanied by reasonable details of the Relevant Item
      in respect of which the Reference Notice is given and, unless the Director
      otherwise consents, shall be given not later than:

      (1)  the first day of October immediately preceding the first of the
           Charging Years in respect of which the Appointee wishes the change to
           the Adjustment Factor to take effect; or

      (2)  if later, where the Director has given a notice to the Appointee
           under paragraph 15 in respect of the same Charging Year, within
           fourteen days from the receipt by the Appointee of that notice.

15.   Changes to the Adjustment Factor initiated by the Director relating to
      Notified Items and Relevant Changes of Circumstance

      In the case of a Notified Item or where any Relevant Change of
      Circumstance has occurred or is to occur, the Director may, having given
      notice to the Appointee specifying the Notified Item or, as the case may
      be, the Relevant Change of Circumstance, of his intention so to do not
      later than:

      (1)  the first day of October immediately preceding the first of the
           Charging Years in respect of which he proposes the change to the
           Adjustment Factor to take effect; or

      (2)  if later, where the Appointee has given a Reference Notice to the
           Director in respect of sub-paragraph 14.2 in respect of the same
           Charging Year, within fourteen days from the receipt of the Director
           of that Reference Notice

      determine the questions set out in sub-paragraph 14.2 in respect of that
      Notified Item or, as the case may be, that Relevant Change of
      Circumstance. A single notice may be given under this paragraph 15 in
      respect of any number of Notified Items and Relevant Changes of
      Circumstances and subparagraph 14.2 shall be construed accordingly. Where
      sub-paragraph 14.2(2) or 15(2) applies, the questions set out in (5) to
      (9) inclusive of sub-paragraph 14.2 shall be determined in respect of all
      Notified Items and Relevant


                                       48

      as if it were a scheme made under section 76 by the Appointee shall be
      treated as a charges scheme in accordance with section 76.

4.    Any such charges scheme as is required to be in effect by virtue of
      sub-paragraph 2.1(2) shall provide that in the case of a connection to a

           person liable to pay the relevant charges,

      (2)  an amount equal to the Installment Amount shall be paid in each of

5.    The Appointee shall:

      (1)  inform persons who inquire about charges for such connections as are
           described in section 79(2) that it is required to have in effect a

         if and whenever requested to do so by the Director but not more
         frequently than once a year, review the Code and the manner in which it
         has been operated, with a view to determining whether any modification
         should be made to it or the manner of its operation.

4.       In carrying out any review of, or making any substantive revision of,
         the Code or in operation (whether under paragraph 3 or otherwise) the
         Appointee shall consult the Customer Service Committee and shall
         consider any representations made by it about the Code or the manner 
         in which it is likely to be or, as the case may be, has been operated.

5.       The Appointee shall submit to the Director for his approval any
         revision of the Code which, after consulting the Customer Service
         Committee if so required under paragraph 4, it wishes to make.

6.       The Appointee shall make such modifications to the Code and any
         revision of the Code as the Director, after prior consultation with the
         Appointee, may specify within two months of the date on which the Code

                  in the form approved, or deemed approved, by the Director) to
                  the Customer Service Committee;

         (2)      with every demand for payment of charges which are fixed by

         without additional excavation at the time the meter is installed the
         Appointee shall repair the leak at the Appointee's expense. Where as a
         result of that check a leak is detected which cannot be repaired
         without additional excavation, the Appointee shall notify the customer

8.3      Subject to sub-paragraph 8.2. where after a meter has been installed, a
         subsequent meter reading indicates that a customer has an abnormally
         high consumption which could be due to an undetected leak in the supply
         pipe, then if a leak is subsequently discovered the Appointee shall
         make an adjustment to the customer's measured charges provided that the
         customer (or the owner responsible for the supply pipe) carries out the
         necessary remedial work at the customer's, or as the case may be, the
         owner's direction and expense within a reasonable period of time
         specified by the Appointee. The Appointee shall not be required to make
         such an adjustment in the event or a subsequent leak or where a leak
         has been caused through the negligence of the customer (or the owner
         responsible for the supply pipe) or their respective agents or when the
         customer knew or ought to have known that there was a leak and failed
         to repair it.

8.4      Where the Appointee is required to make an adjustment to the customer's
         measured charges under sub-paragraph 8.3, the adjustment shall be based
         upon the customer's past normal consumption. Where there is no record
         of past consumption the adjustment shall be based upon typical usage
         for property of a similar type and the customer's measured charges
         shall be further adjusted if the customer's subsequent accrual usage is
         significantly different.

8.5      Where the Appointee is required to make an adjustment to a customer's
         measured charges for water supply under this paragraph it shall make a
         similar adjustment to the customer's measured charges for sewerage
         services, provided that where sewerage services are provided in
         relation to the same premises by a different undertaker then the
         Appointee shall inform that undertaker as soon as reasonably
         practicable that the Appointee is required to make such an adjustment
         to the customer's measured charges for water supply and of the basis on
         which the adjustment has been, or will be, made.

8.6      Where the Appointee is informed by any water undertaker that it is
         required to make an adjustment to a customer's measured charges for a
         supply or water to any premises in relation to which the Appointee
         provides sewerage services the Appointee shall make an adjustment to
         the customer's measured charges for sewerage services on a basis
         similar to that made by that water undertaker.

                                    enquiry, any Associated Company, has a
                                    material direct or indirect interest, shall,
                                    following the proposed disposal, have,
                                    either as a result of the proposed disposal
                                    or any other transaction, a continuing
                                    interest whether direct or indirect in the
                                    protected land the subject of the proposed
                                    disposal or in any development involving or
                                    connected with that protected land: and

         (2)      prior to entering into the relevant obligation, furnish to the
                  Director in writing such further Information regarding the
                  proposed disposal which the Director may reasonably request.

4.4      For the purpose of sub-paragraph 4.3(1)(g)(iv), "interest" includes an
         entitlement to a share of profits or participation in assets, rights or
         benefits but excludes any interest which consists solely of an
         entitlement to receive installments of consideration which as to amount
         and timing are certain or variable only by reference to the grant of
         planning permissions.

         subparagraph 4.3(1)(g)(iii), furnish to the Director a certificate by a
         valuer appointed by the Appointee ("the Valuer") addressed to the
         Director which states that in the opinion of the Valuer the
         consideration certified under sub-paragraph 4.3(1)(g)(ii) is the best
         price that could reasonably be obtained for the protected land in
         question, having regard to all the circumstances at the time when the
         certificate is given (including, but without limitation, any reasonable
         prospect of planning permissions being obtained).

4.6      where the Appointee proposes to make any such disposal as is mentioned
         in sub-paragraph 4.1 and the terms or circumstances of the proposed
         disposal are such that a Disposal Certificate giving the full
         confirmation required by (f) or (g) of sub-paragraph 4.3(1) (including,
         where relevant, such a certificate as is referred to in sub-paragraph
         4.5) cannot properly be given, the Appointee shall not enter into any
         obligation (whether conditional or subject to conditions) which
         requires or might require it to make that proposed disposal unless:


                                      104

         sub-paragraph 4.3(1) including, where relevant, such a certificate as
         is referred to in sub-paragraph 4.5) cannot properly be given:

         (a)      either:

                  (i)      not less than 10 working days prior to the Appointee
                           entering into the relevant obligation, the Appointee
                           has furnished to the Director a Disposal Certificate
                           as required by sub-paragraph 4.3 including such of
                           the matters specified in (g) as can properly be
                           certified and a by a valuer appointed by the
                           Appointee and approved by the Director for the
                           purpose of this sub-paragraph ("the Valuer")
                           addressed to the Director which states:

                           (A)      that in the opinion of the Valuer the
                                    consideration to be received by the
                                    Appointee from the proposed disposal is the
                                    best price likely to be obtained for the
                                    land in question, having regard to all the
                                    circumstances at the time when the
                                    certificate is given (including, but without
                                    limitation, any reasonable prospect of
                                    planning permissions being obtained); and

                           (B)      the amount of the consideration to be
                                    received or expected to be received by the
                                    Appointee from the proposed disposal
                                    expressed in cash according to when that
                                    consideration is to be, or is expected to
                                    be, received; or

                  (ii)     the Director gives his prior written consent to the
                           proposed disposal, such consent not to be
                           unreasonably withheld or delayed; and

         (b)      prior to entering into the relevant obligation, the Appointee
                  shall have furnished to the Director in writing such further
                  Information regarding the proposed disposal which the Director
                  may reasonably request; and

         (c)      where the amount. stated pursuant to sub-paragraph
                  (1)(a)(i)(A) above exceeds the Consent Limit, the prior
                  written consent of the Director to the proposed disposal has
                  been obtained, such consent not to be unreasonably withheld or
                  delayed:

(2)      in any case where the full confirmation required by (f) of
         sub-paragraph 4.3(1) cannot properly be given, the prior written
         consent of the Director to the proposed disposal has been obtained,
         such consent not to be unreasonably withheld or delayed.

5.       Disposals of protected land by auction or formal tender

5.1      Where the Appointee proposes to dispose by auction or formal tender of
         any protected land, the value of which (when aggregated with the value
         of any other such protected land as is described in sub-paragraphs
         4.2(2) (a) and (b)) exceeds the Materiality Amount, it shall:

         (1)      not less than 10 working days prior to the date of the auction
                  or the invitation to tender:

                           appointed by the Appointee ("the Valuer") addressed

         5.1(1)(a)(i) or (iii) cannot properly be given, the Appointee shall not
         proceed with the proposed disposal without the prior written consent of
         the Director.

         Disposal) of protected land to any Associated Company, not being land
         which has previously been the subject of a transfer under paragraph 7,
         unless:

                  conditional or subject to conditions) which requires or might
                  require it to make that proposed disposal (a "relevant
                  obligation") it notifies the Director in writing that it
                  proposes to make the proposed disposal; and

         (2)      either:

                           entering into a relevant obligation as may reasonably
                           be specified by the Director, having regard to the
                           aggregate number of proposed disposals by the
                           Appointee to Associated Companies and of any other

                           to the matters referred to in sub-paragraph (2)(a));
                           and

         (3)      prior to entering into a relevant obligation, the Appointee

                  considers appropriate to such that the Appointee receives such
                  share of any value to be derived or expected to be derived by
                  the Associated Company from the land in question as the

                  exceeds the Consent Limit the prior written consent of the
                  Director to the proposed disposal has been obtained, such

         not to be unreasonably withheld or delayed having regard, inter alia,
         but without prejudice to the generality of the foregoing, to the
         matters referred to in sub-paragraph 6.1(2)(a)).

         purposes connected with carrying out the Regulated Activities the
         Appointee shall comply with the provisions of sub-paragraph 7.3.

7.2      For the purposes of sub-paragraph 7.1:

         (1)      the mere fact of the Appointee ceasing to hold or we protected
                  land for purposes connected with carrying out the Regulated
                  Activities shall not be regarded as a change of use of that
                  protected land:

         (2)      any Interim Use of any protected land shall be disregarded,
                  but so that subparagraph 7.1 shall apply to any change of use
                  from an Interim Use (other than a cessation thereof or a
                  change to another Interim Use)

                  use which prior to such extension, intensification or
                  modification was an Interim Use shall constitute a change of
                  use; and

         (3)      the commencement of material works to implement a proposed
                  change of USC shall be deemed to be a change of use.


7.3      The Appointee shall:

         (1)      within 28 days of any inch change of use to which
                  sub-paragraph 7.1 applies:

                                             Appointee, having made due and
                                             careful enquiry, any Associated
                                             Company has any interest or right
                                             and which affect or might affect
                                             the value of such protected land or
                                             the value of which is or might be
                                             affected by such protected land;

                                    (A)      the consideration (if any) to be
                                             received or expected to be
                                             received; and

                                    (B)      separately, any other value which,
                                             in the reasonable opinion of the
                                             Appointee, is to be received or
                                             derived, or expected to be received
                                             or derived

                                             in each case from or in connection
                                             with the New Use by the Appointee
                                             and the timing of the receipt or

                                    of the New Use is no longer required for
                                    carrying out the Regulated Activities and
                                    will not be so required in the foreseeable

                           Value") as to the best price which, in the opinion of
                           the Valuer is likely to be obtained from a disposal
                           of the land in question to an unconnected third
                           party, having regard to all the circumstances at the
                           time when the certificate is given (including, but

                           planning permissions being obtained); and

                  certificate for the value certified by the Valuer to be the
                  best price under sub-paragraph 7.3(1)(b) or for such other
                  value as may subsequently be certified by the Valuer, acting
                  at the request of the Director, to be the best price likely to
                  be obtained from a disposal of the land in question to an
                  unconnected thirty party, having regard to all the
                  circumstances at the time when the certificate is given
                  (including, but without limitation, any reasonable prospect of
                  planning permissions being obtained), provided that where the
                  Valuer subsequently certifies a different value as aforesaid
                  the Appointee shall not be required to make the transfer
                  before the expiry of 12 months from the date of that
                  subsequent certificate and, at the expiry of that period of 12
                  months, the provisions of this sub-paragraph. including this
                  proviso, shall apply mutatis mutandis.

                           procedures so that they were sufficient for those
                           purposes; and

         (2)      include a term that the Assessor will provide such further
                  explanation or clarification of his report as the Director may

                           assumptions by the Appointee or on the basis of the
                           assumptions specified by the Director, if any); or

                  (b)      that the methods and procedures are insufficient for
                           the purposes described in sub-paragraph 3.1 and that

his employees and agents to keep confidential and not to disclose, except to the
Director or as required by law, any Information which the Assessor obtains in
the course of preparing his report.

         prepare his report, including without limitation, so far as is
         necessary for that purpose:

                  prepare his report).

         references to his employees and agents.

         larger than the standard size for the time being adopted by the
         Appointee for new connections of Houses, the Standard Amount multiplied
         by the Relevant Multiplier for those premises; and

2.1.3    in the case of any other premises -

                  Water Infrastructure Charge (pound)X

                  Sewerage Infrastructure Charge (pound)Y
         for details of charges see Schedule

2.2      In respect of each Charging Year starting on or after 1st April 1992-

2.2.1    the amounts specified in sub-paragraph 2.1.3 shall be adjusted by the
         percentage of any change in the Retail Prices Index between that
         published for the month of November in the Prior Year and that
         published for November 1990; and

2.2.2    sub-paragraph 4/5.2 of Condition B shall apply to this Condition as if
         the reference in it to the Charges Limit were a reference to the
         Standard Amount. 
         Note: 4.2 in Water only License, 5.2 in Water and Sewerage Licence.

3.1      Subject to sub-paragraph 3.2, where an amount has been paid or agreed
         to be paid to the Appointee on account of works which have been allowed
         for in determining the limits on Infrastructure Charges under the
         Appointment, that amount shall, to the extent that it is actually paid
         and is referable to a connection, count towards the level of charge for
         that connection under paragraph 2.

3.2      Where any such amount referable to a connection is greater than the
         level of charge for that connection under paragraph 2, nothing in this
         Condition shall preclude the Appointee from retaining or recovering the
         greater amount.

1.       Where, prior to 1st April 1990 the Appointee has entered into an
         agreement under which a person has agreed to pay an amount in respect
         of works referable to a connection and that amount is greater than the
         amount which would otherwise be charged pursuant to paragraph 2,
         nothing in this Condition shall preclude the Appointee from recovering
         the greater amount. Note: the previous reference, in brackets, to
         statutory provisions are now dealt with at 6.2.

5.1      Subject to sub-paragraph 5.2, where a site is developed or redeveloped
         (including by means of conversion of a building or buildings on it) the
         total amount of Water Infrastructure Charges or, as the case may be,
         Sewerage Infrastructure Charges which may be recovered in respect of
         Houses and other premises on the site resulting from the development or
         re-development shall not exceed the Standard Amount multiplied by X,
         where X equals -

         (1)      the aggregate of the Relevant Multipliers for all those
                  premises less

         (2)      the maximum number of premises with water or, as the case may
                  be, sewerage connections on the site at any time in the period
                  of 5 years before the development or redevelopment began.

5.2      For the purpose of calculating the amount of the limit imposed by this
         paragraph

         (a)      each premises to which sub-paragraph 2.1.3 applies shall be
                  deemed to have a Relevant Multiplier of 1; and

         (b)      where, by virtue of paragraph 3 or 4 of this Condition, the
                  Appointee would be permitted to charge more in respect of any
                  premises resulting from the development or redevelopment than
                  the level otherwise applying under paragraph 2, the limit
                  shall be increased by the amount of the excess.

6.1      Subject to subparagraph 6.2, where

         (a)      a person who has received a demand, or undertaken, to pay
                  Infrastructure Charges in respect of 2 or more Houses subject
                  to a Common Billing Agreement fails to pay them, or any part
                  of them, within 14 days of the date of connection; or

         (b)      a Common Billing Agreement is terminated otherwise than in
                  accordance with its terms by the person who has undertaken to
                  pay charges under it,

         nothing in this Condition shall preclude the Appointee from recovering,
         whether from that person or from the occupier of each House subject to
         the Infrastructure Charges in respect of that House at the Standard
         Amount.

6.2      whenever it takes advantage of sub-paragraph 6.1, the Appointee shall
         give credit for any amount already paid by way of Infrastructure
         Charges in respect of that House for the connection concerned.

7.       Paragraph 2 does not apply to the interest element of any Installment
         Amount payable in accordance with Condition D.

8.1      Nothing in this Condition precludes the Appointee from charging less in
         any particular case than the level of Infrastructure Charge applying
         under paragraph 2.

8.2      Nothing in this Condition restricts the recovery or amount of any
         expenses or charges recoverable otherwise than under section 79 of the
         Act or (except if and to the extent that sub-paragraph 3.1 applies to
         the amount) restricts the recovery or level of any Infrastructure
         Charge by reference to any such amount.

9.       Notification to Sewerage Undertakers

         Where the Appointee makes a connection or connections to premises in
         respect of water supply services, it Shall as soon as reasonably
         practicable inform any sewerage undertaker which provides services to
         those premises of the number of premises connected, the date or dates
         of connection, the address(es) of the premises, the name and address of
         the person(s) responsible for payment of charges for the supply of
         water to the premises and (if different) of the person(s) responsible
         for payment of Infrastructure Charges in respect of the premises and
         (where appropriate) the Relevant Multiplier(s) for the premises.

10       Arbitration

         If, in any case to which a adevant Multiplier applies, there is any
         dispute between the Appointee and the person on whom any Infrastructure
         Charge has been levied about the calculation of the Relevant
         Multiplier, or the number or type of fittings on which that calculation
         is based, it may be referred by either party for determination by the
         Director.

11.      Periodic Review of Level of Infrastructure Charges

11.1     Where a Periodic Review is to be carried out under paragraph 8, 9 or 10
         of Condition B, the Appointee may, by notice given to the Director in
         relation to water or sewerage connections or both, refer to the
         Director, for determination by him the question whether any (and if so,
         what) change to the Standard Amount or the manner of calculation of any
         Relevant Multiplier should be made for the 10 consecutive Charging
         Years to which that review relates.

11.2     Where a Periodic Review is to be carried out under paragraph 8, 9 or 10
         of Condition B, the Director may, after giving notice to the Appointee
         in relation to water or sewerage connections or both, determine the
         question specified in sub-paragraph 11.1.

11.3     Notice under sub-paragraph 11.1 or 11.2 shall be given not later than
         30 days after the Review Notice Date for the Periodic Review concerned.

12.      Interim Review of Level of Infrastructure Charges

12.1     The Appointee may, by notice given to the Director in relation to water
         or sewerage connections or both, refer to the Director, for
         determination by him, the question whether any (and if so, what) change
         to the Standard Amount or the manner of calculation of any Relevant
         Mutliplier should be made, in respect of the Subsequent Period, in
         order to ensure that -

         (a)      in each Charging Year in that period, the aggregate number of
                  water, or as the case may be, sewerage connections made by the
                  Appointee bears the same proportion to its aggregate revenue
                  from Water Infrastructure Charges or, as the case may be,
                  Sewerage Infrastructure Charges as the aggregate number of
                  such connections assumed by the Secretary of State for that
                  year in setting the initial level of those charges under this
                  Condition bears to the aggregate revenue so assumed by him;
                  and

         (b)      over the Subsequent Period any shortfall in (or excess of)
                  revenue from Infrastructure Charges in any Charging Year in
                  the Prior Period, compared with the revenue so assumed for
                  that year, is recovered (or, as the case may be, carried
                  forward as a credit) to the extent attributable to any
                  difference in those proportions in respect of that year.

12.2     In sub-paragraph 12.1 "the Subsequent Period" means the period from 1st
         April immediately following the Charging Year in which the reference is
         made under 31st March 1995 (or, if there is no Periodic Review at the
         first 5-yearly interval, 31st March 2000) and "the Prior Period" means
         the period from 1st April 1991 until the end of the Charging Year in
         which the reference is made.

12.3     The Director may, after giving notice to the Appointee in relation to
         water or sewerage connections or both, determine the question specified
         in sub-paragraph 12.1.

12.4     Notice under sub-paragraph 12.1 or 12.3 may be given not more than once
         in any Charging Year and not later than 31st December.

                                    APPENDIX

                        CALULATION OF RELEVANT MULTIPLIER


1.       To calculate the Relevant Multiplier for a House to which
         sub-paragraph 2.1.1 of Condition C applies:

         1.1      ascertain in respect of all the Houses subject to the Common
                  Billing Agreement in question (eg all the flats in a block to
                  which such an agreement applies) and all communal facilities
                  shared by all or any of them, the total number of water
                  fittings in all the categories specified in column 1 of the
                  Table below;

         1.2      calculate by reference to column 2 of the Table the aggregate
                  loading units attributable to that total number of water
                  fittings (and increase the aggregate, where necessary, to take
                  account of the minimum for domestic appliances);

         1.3      divide that number of loading units by 24 and divide the
                  resulting figure by the number of Houses subject to the Common
                  Billing Agreement;

         1.4      the resulting number, will be the Relevant Multiplier.


2.       To calculate the Relevant Multiplier for premises to which
         sub-paragraph 2.1.2 of Condition C applies, ascertain in respect of the
         premises the total number of water fittings in all the categories
         specified in column 1 of the Table below; calculate by reference to
         column 2 of the Table the aggregate loading units attributable to that
         total number of water fittings; divide the aggregate loading units by
         24; and the resulting number will be the Relevant Multiplier, provided
         that if the resulting number is less than 1, the Relevant Multiplier
         will be 1.

CONDITION C:  INFRASTRUCURE CHARGES

Explanatory Note

(This note does not form part of the Condition and does not affect the
interpretation of it)

1.       Section 79(2) of the 1989 Water Act introduced a power whereby water
         and sewerage undertakers could levy a charge for the initial connection
         of premises to a water supply or to a public sewer for domestic
         purposes. These charges, which were first levied from 1st April 1990,
         are termed "infrastructure charges". They relate to the additional
         capital expenditure costs incurred by undertakers in extending the
         network of reservoirs, mains, sewers and treatment works, and
         developing other resources, to provide capacity for new customers.

2.       This Condition places limits (which are different for each company) on
         the amount of the infrastructure charges for each water or sewerage
         connection. It also contains provisions for adjusting charges. The
         Condition is structured as follows:

         -        Paragraph 1 deals with matters of intepretation and contains
                  definitions of terms used in this Condition. (Definitions of
                  terms common to all Conditions are included in Condition A);
         -        Paragraphs 2 to 8 deal with the level of infrastructure
                  charges, and paragraphs 11, 12 and 14 contain general
                  provisions for reviewing the levels of charges;
         -        Paragraphs 9 and 13 are concerned with the provision of
                  information;
         -        Paragraph 10 provides for arbitration in specified
                  circumstances.

         The Condition applies only to charges under s.79(2), and does not apply
         for example, to amounts recoverable under sections 41, 42 or 72 of the
         1989 Act, or s.36 of the Public Health Act 1936, or any local
         enactment.

3.       The intention of the Condition, in placing a limit on infrastructure
         charges levied in different situations, is to reflect broadly and
         expected additional load placed on the system by different categories
         of property. In the case of house and flats with a common supply pipe
         and subject to a common billing agreement for water supply and sewerage
         services, and in the case of properties (other than house and flats)
         served by pipes larger than the standard size, the standard charge set
         out in paragraph 2 is increased by a multiplier reflecting estimated
         loadings. The basis on which these loadings are to be calculated is set
         out in the Appendix to the Condition. Paragraph 2 also provides for the
         levels of charge to be adjusted annually by the change in the retail
         prices index.

4.       Paragraphs 3 and 4 deal with cases where an amount has been agreed to
         paid in respect of a connection which meets (wholly or in part) the
         cost of infrastructure related to the connection.

5.       Where a site is redeveloped or a building is converted paragraph 5
         provides that credit shall be given for the number of premises on the
         site in the five years beforehand, in calculating the limit on
         infrastructure charges.

6.       Paragraph 6 provides that, where infrastructure charges are calculated
         on the basis of the multiplier in cases where a common billing
         agreement exists, and either they are not paid in full within 14 days
         of the date of connection, or the agreement is terminated prematurely
         by the customer, charges can be recovered at the standard rate.




                                       11
<PAGE>   152


7.       Under Paragraph 11 the levels of infrastructure charge can be reviewed
         at the same time that the K factor specified in Condition B is
         reviewed. Paragraph 12 provides for interim determinations up to the
         first periodic review, to ensure that the average charge per connection
         remains at the level originally intended, taking account of fresh
         information about the mix of connections and their relative loading.

8.       Paragraph 10 provides for arbitration by the Director General where
         there is a dispute about the calculation of the multiplier in cases
         where one applies.

9.       The revised Condition (and especially the three possible bases for
         calculating charges - see Paragraph 3 above) will have the effect that
         individual charges should more nearly reflect the differing estimates
         of additional demand, for new capacity upon the undertakers systems,
         which arise from the domestic element of various types of development.
         In order to assess the extent to which this is achieved, the Director
         General will collect, from each undertaker, information about numbers
         and types of connections in each category.

         1(5), variations of:

         (1)      the matters required to be shown or disclosed under
                  sub-paragraph 5.1(1) (but not so as to require separate

         Business and any Associated Company (or between the Appointed Business
         and any other business or activity of the Appointee) is at arm's
         length so that neither gives to nor receives from the other any
         cross-subsidy.

6.2      Subject to sub-paragraphs 6.3 to 6.7, accounting statements prepared
         under paragraph 4 shall disclose in relation to each transaction of a
         description specified in the first column of the Appendix to this
         Condition which took place during the financial year to which those
         statements relate, the company or, as the case may be, the business or
         activity which was party to the transaction with the Appointee or, as
         the case may be, the Appointed Business or which otherwise benefitted
         from the transaction and the information in relation to that
         transaction specified in the second column of that Appendix.

         and any other business or activity of the Appointee) exceeds 0.5% of
         the turnover of the Appointed Business, or (pound)100,000, whichever is
         the greater, then that transaction shall not be aggregated under
         sub-paragraph 6.3 and the Appointee shall include in any accounting
         statement prepared under paragraph 4 the information about that
         transaction which is specified in the Appendix in relation to a
         transaction of that kind and which complies with any guidelines issued

6.6      Nothing in sub-paragraph 6.2 shall require the disclosure of any

         under paragraphs 3, 4, 5 and 6 of the Appendix relating to transactions
         with the same company or other business or activity of the Appointee is
         not material to the Appointed Business as a whole. For the avoidance of
         doubt, if the aggregate of such amounts is material to the Appointed
         Business as a whole then information shall be disclosed in accordance
         with this paragraph and the Appendix in relation to each such
         transaction (subject always to sub-paragraph 6.3). For the purpose of
         this sub-paragraph the question whether an amount is material to the
         Appointed Business as a whole shall be determined by the Auditors by
         reference to whichever is the greater of:

         (1)      the book value of the asset or liability the subject of, or
                  affected by, the transaction; and

         (2)      the consideration or other charge given, paid or waived.

                               MADE: 28 MARCH 1994
                        COMING INTO EFFECT: 1 APRIL 1994



   Part IV.  Interim Determinations

13.      Matters of interpretation and construction which apply for the purposes
         of this Part IV

13.1     In this Part of this Condition:

         "THE APPROPRIATE DISCOUNT RATE" means such rate of return as, at the
         time at which the Appropriate Discount Rate falls to be applied from
         time to time under this Condition, investors and creditors would
         reasonably expect of a properly managed company holding the
         Appointments whose sole business consists of being a water undertaker
         and a sewerage undertaker and, without excluding other considerations
         which may also be relevant, having its equity share capital listed on
         The International Stock Exchange of the United Kingdom and the Republic
         of Ireland Limited, and the same Appropriate Discount Rate shall be
         applied for all purposes in determining questions the subject of the
         same reference (including questions determined by the Director under
         paragraph 15 when he determines questions referred to him by the
         Appointee under paragraph 14);

         "EQUITY SHARE CAPITAL" has the same meaning as in the 1985 Act;

         "INTERIM DETERMINATION" means the determination by the Director of the
         relevant questions the subject of a reference by the Appointee under
         paragraph 14 or pursuant to paragraph 15 or, as the case may be, the
         determination by the Monopolies Commission of the relevant questions or
         of the disputed determinations the subject of a reference to it
         pursuant to sub-paragraph 16(2) or 16(3), which relates to a reference
         by the Appointee under paragraph 14 or a determination pursuant to
         paragraph 15;

         "MAKING A RELEVANT DETERMINATION" means determining the Adjustment
         Factor initially or determining, in carrying out the most recent
         Periodic Review or making any subsequent Interim Determination (or,
         where there has been no Periodic Review, in making any Interim
         Determination) whether the Adjustment Factor should be changed (and, if
         so, what change should be made to the Adjustment Factor), and "Relevant
         Determination" shall be construed accordingly; r



                                       1
<PAGE>   166

         "NET PRESENT VALUE" means the net present value calculated as at 30
         September in the year in which the relevant Reference Notice is given
         or, where in any year no Reference Notice is given under paragraph 14
         but the Director gives a notice to the Appointee under paragraph 15, as
         at 30 September in the year in which the Director gives the notice, by
         discounting subsequent cash flows and inflating earlier cash flows at
         the Appropriate Discount Rate, assuming all cash flows in any Charging
         Year occur on 30 September in that charging Year;

         a "NOTIFIED ITEM" is any item notified by the Director to the Appointee
         as not having been allowed for (either in full or at all) in making a
         Relevant Determination; and for the purpose of this definition:

                  (a)      where any such item was not allowed for in full then
                           it shall only be a Notified Item to the extent that
                           it was not allowed for; and

                  (b)      where, in determining whether the Adjustment Factor
                           should be changed (and if so what change should be
                           made to the Adjustment Factor), the Director, or, as
                           the case may be, the Monopolies Commission, allows
                           for any such item as was previously so notified by
                           the Director then references in this Condition to
                           Notified Items and Relevant Items shall be taken, for
                           the purposes of any subsequent Interim Determination,
                           to exclude such item to the extent that the Director,
                           or, as the case may be, the Monopolies Commission,
                           allowed for it as aforesaid;

         a "RELEVANT CHANGE OF CIRCUMSTANCE" is any of the following:

         (1)      (a)      the application to the Appointee of any legal
                           requirement; and

                  (b)      any change to any legal requirement which applies to
                           the Appointee (including any legal requirement
                           ceasing to apply, being withdrawn or not being
                           renewed);

         (2)      either of the following circumstances for any Charging Year in
                  respect of which the Secretary of State, or, as the case may
                  be, the Director, notified the Water Authority or, as the case
                  may be, the Appointee that variations in value received or
                  expected to be received from Relevant Disposals of Land shall
                  constitute a Relevant Change of Circumstance:

                  (a)      where for any Charging Year the value received or
                           expected to be received from a Relevant Disposal of
                           any Identified Land is, or is expected to be,
                           different from the value which the Secretary of
                           State, or, as the case may be, the Director, notified
                           the Water Authority or, as the case may be, the
                           Appointee was the value attributable to a Relevant
                           Disposal of that Identified Land for that Charging
                           Year which had been allowed for in determining the
                           Adjustment Factor initially or whether the Adjustment
                           Factor should be changed (and if so what change
                           should be made to the Adjustment Factor);

                  (b)      where for any Charging Year, and to the extent not
                           taken into account under (a) above, the aggregate
                           value received or expected to be received from
                           Relevant Disposals of Non-identified Land is, or is
                           expected to be, different from the value which the
                           Secretary of State, or, as the case may be, the
                           Director, notified the Water Authority or, as the
                           case may be, the Appointee was the value attributable
                           to Relevant Disposals of Non-identified Land for that
                           Charging Year which had been allowed for in
                           determining the Adjustment Factor initially or
                           whether the Adjustment Factor should be changed (and
                           if so what change should be made to the Adjustment
                           Factor)

                  and so that any notification by the Director for purposes of
                  this sub-paragraph shall be relevant for the purposes of this
                  sub-paragraph (2) to the exclusion of any earlier notification
                  by the Secretary of State or the Director for the purposes of
                  this sub-paragraph (2) to the extent that the first-mentioned
                  notification is made in respect of matters in respect of which
                  that earlier notification was made.

                           received or expected to be received in the Charging
                           Year in which it is received or expected to be
                           received;

                  (viii)   references to "VALUE RECEIVED OR EXPECTED TO BE
                           RECEIVED" shall be construed so as to include
                           receipts by, and grants to, the Appointee, any
                           Associated Company or any other business in which
                           either the Appointee or any Associated Company has a
                           material direct or indirect interest;

                  (ix)     for the purpose of COMPUTING "VALUE RECEIVED OR
                           EXPECTED TO BE RECEIVED" in respect of a Relevant
                           Disposal of Land which consists of a transfer made
                           under paragraph 7 of Condition K the "value received
                           or expected to be received" shall be the value for
                           which that transfer is made under that paragraph 7,
                           but so that where that value includes a right to
                           receive cash or any other asset then, for the purpose
                           of this sub-paragraph, no value shall be attributed
                           to that right but the cash or other asset the subject
                           thereof shall be included and treated as value
                           received or expected to be received in the Charging
                           Year in which it is received or expected to be
                           received;

                  (x)      in the case of a right or benefit, but subject to the
                           proviso to (vii) above, value shall be deemed to have
                           been received at the time the right is granted or the
                           benefit arises;

         (3)      where:

                  (i)      in making a Relevant Determination, an amount has
                           been allowed for on account of steps taken or to be
                           taken for the purpose of securing or facilitating
                           compliance with a legal requirement (not being one to
                           comply with which the Water Authority or the
                           Appointee has determined to make a change to the
                           basis on which it charges customers for water supply
                           or sewerage services) or achieving a service standard
                           adopted or to be adopted by the Appointee; and

                  (ii)     in any such case:

                           (A)      the Appointee has not taken (by the date by
                                    which it was assumed for the purposes of
                                    assessing the amount allowed for as
                                    aforesaid it would take those steps) any or
                                    all of those steps which, for the purpose of
                                    assessing the amount allowed for as
                                    aforesaid, it was assumed it would take; and

                           (B)      as a result, the amount allowed for as
                                    aforesaid is substantially greater than the
                                    sum of (a) the costs (if any) actually
                                    incurred by the Appointee for the relevant
                                    purpose specified in (i) above and (b) so
                                    much (if any) of that amount as has been
                                    otherwise offset by prudent management of
                                    the capital programme; and

                           (C)      that purpose has not been otherwise
                                    achieved;

a "Relevant Item" is any of the following:

         (1)      A Relevant Change of Circumstance (other than a Relevant
                  Change of Circumstance falling within sub-paragraph (2) of the
                  definition);

         (2)      A Notified Item; and


         (3)      A Relevant Disposal of Land

         and references to a Relevant Item are to a Relevant Change of
         Circumstance (other than a Relevant Change of Circumstance falling
         within sub-paragraph (2) of the definition), a Notified Item or a
         Relevant Disposal of Land as the context may require.

         purpose of that definition

    (1)  a "LEGAL REQUIREMENT" is any of the following:

         (a)      any enactment or subordinate legislation to the extent that it
                  applies to the Appointee in its capacity as a water undertaker
                  or sewerage undertaker (and for this purpose, but without
                  prejudice to the generality of the foregoing, "subordinate
                  legislation" includes any order made under section 20 and any
                  authorisation granted, approval given, or prohibition imposed,
                  by the Secretary of State under The Water Supply (Water

                  undertaker, or decision taken by the said Commission which is
                  binding on the Appointee in its capacity as a water undertaker
                  or sewerage undertaker and to the extent that it is so
                  binding;

         (c)      any licence, consent or authorisation given or to be given by
                  the Secretary of State, the Authority or other body of
                  competent jurisdiction to the Appointee for the purpose of
                  carrying on any of the functions of a water undertaker or
                  sewerage undertaker;

         (d)      any undertaking given by the Appointee to. and accepted by,
                  the Secretary State or, as the case may be, the Director for
                  the purposes of section 20(5)(b);

         (e)      other than any such undertaking as is referred to in (d), any
                  undertaking given by the Appointee to any enforcement
                  authority, and accepted by that enforcement authority, to take
                  all such steps:

                  (i)      as are specified by that enforcement authority to be
                           necessary or appropriate for the Appointee to take
                           for the purpose of securing or facilitating
                           compliance with any legal requirement in relation to
                           which that enforcement authority is the enforcement
                           authority; or

                  (ii)     the taking of which is specified by that enforcement
                           authority to be a condition or requirement of
                           granting or renewing any such licence, consent or
                           authorisation as is referred to in (c) or agreeing
                           not to withdraw the same;

         (f)      the Conditions of these Appointments; and

         (g)      any interpretation of law, or finding, contained in any
                  judgment given by a court or tribunal of competent
                  jurisdiction in respect of which the period for an appeal has
                  expired which requires any legal requirement falling within
                  (a) to (b) above to have effect in a way;

                  (i)      different to that in which it previously had effect;
                           or

                  (ii)     different to that in which it was taken to have
                           effect:

                           (A)      for the purpose of determining the
                                    Adjustment Factor or, as the case may be,

                           (B)      in determining whether the Adjustment Factor
                                    should be changed (and if so what change
                                    should be made to the Adjustment Factor)

but so that nothing in sub-paragraphs (a) to (g) above shall apply so as to
include:

                  (i)      any such legal requirement as is referred to in
                           section 113 or 129, or

                  (ii)     those sections

to the extent in either case that they require the Appointee to pay fees or the
relevant enforcement authority; and charges to

         (2)      "enforcement authority" means any person or body having 
                  jurisdiction or to take action under or in respect of the 
                  relevant legal requirement.

13.3     In paragraph 14 and in the definition of a "Relevant Change of
         Circumstance": to enforce

         (1)      references to costs include references to expenditure and loss
                  of revenue and references to costs being incurred include
                  references to expenditure being made and loss of revenue being
                  suffered; and

         (2)      references to receipts include references to receipts, cash or
                  other assets of any sort, whether of a capital or revenue
                  nature and including receipts of grants, contributions, gifts
                  and loans.

13.4 (1) For the purposes of sub-paragraph 14.2(1) costs, receipts and
         savings shall be ascertained at the general price level prevailing, or
         expected to prevail, on 30 September in the year in which the Appointee
         gives notice under sub-paragraph 14.1, or the Director gives notice
         under paragraph 15(1).

         (2)      In sub-paragraphs 14.2(8) and 14.2(9) and sub-paragraph (3)
                  below "at Outturn Prices", in relation to the amount of any
                  Base Cash Flow or depreciational means that amount as adjusted
                  to take account of the actual or expected cumulative
                  percentage change in the Retail Prices Index from that
                  prevailing, or expected to prevail, on 30 September in the
                  year in which the Appointee gives notice under subparagraph
                  14.1, or the Director gives notice under paragraph 15(1), up
                  to and including that prevailing, or expected to prevail, on
                  30 September in the year in which the Base Cash flow or
                  depreciation occurred, or is expected to occur.

         (3)      In sub-paragraph 14.2(8) "Current Value", in relation to any 
                  Base Cash Flow or depreciation at Outturn Prices, means that
                  amount, as adjusted to take account of the actual or expected
                  cumulative percentage change in the Retail Prices Index from

                  depreciation occurred or is expected to occur, up to and
                  including 30 September in the relevant year.

13.5     For the purpose of section 15(5)(b), the provisions of this Condition,
         to the extent that they relate to a Relevant Change of Circumstance
         falling within sub-paragraph (2) of that definition, are provisions of
         the Appointments which cannot be modified. This sub-paragraph shall
         cease to have effect if, but only if, this Condition ceases to contain
         any provision relating to changes to the Adjustment Factor to allow for
         Notified Items and Relevant Changes of Circumstance.

14.      References to the Director relating to Notified Items and Relevant
         Changes of Circumstance

14.1     The Appointee may from time to time refer to the Director for
         determination by him (having considered the proposals of the Appointee)
         the questions set out in sub-paragraph 14.2. Such reference shall be
         made by notice given to the Director, which shall be given in
         accordance with sub-paragraph 14.4. For the purposes of sub-paragraph
         14.2 a single reference may be made in respect of any number of
         Notified Items and Relevant Changes or Circumstance and sub-paragraph
         14.2 shall be construed accordingly.

15.      In the case of a Notified Item or where there has been or is to be a
         Relevant Change of Circumstance all of the following:

         (1)      what are, or are likely to be, the costs, receipts and savings
                  reasonably attributable to the Relevant Item and also, in the
                  case of a Relevant Change of Circumstance falling within
                  sub-paragraph (2) of the definition, the costs, receipts and
                  savings reasonably connected with the Relevant Disposal of
                  Land;

         (2)      except in the case of a Relevant Change of Circumstance
                  falling within sub-paragraph (2) of the definition, to what
                  extent:

                  (a)      are the costs determined under (1) reasonably
                           recoverable through charges for services provided,
                           functions carried out by, and other activities of,
                           the Appointee in its capacity as a water undertaker
                           or sewerage undertaker which are not Standard Charges
                           for Basket Items (not being Excluded Charges);




                                       7
<PAGE>   172



                  (b)      in the case of receipts and savings, is the Relevant
                           Item relevant to services provided, functions carried
                           out by, and other activities of, the Appointee as a
                           water undertaker or sewerage undertaker which are not
                           Basket Items in respect of which the Appointee makes
                           Standard Charges (not being Excluded Charges)

                  and where it is determined that such costs are reasonably
                  recoverable as aforesaid or, as the case may be, that the
                  Relevant Item is relevant as aforesaid, either in full or to
                  an extent, then references hereafter to costs, receipts and
                  savings reasonably attributable to a Relevant Item are to
                  those costs, receipts and savings except to that extent;

         (3)      both of the following:

                                                                                
                  (a)      what costs reasonably attributable to, or connected
                           with, the Relevant Item as determined under (1) and
                           what dining of incurring of such costs are
                           appropriate and reasonable for the Appointee in all
                           the circumstances to incur and programme, or, as the
                           case may be, to have incurred and programmed, by
                           reason of the Relevant Item; and

                  (b)      what receipts and savings reasonably attributable to,
                           or connected with, the Relevant Item as determined
                           under (1) and what timing of such receipts and
                           savings is appropriate and reasonable for the
                           Appointee in all the circumstance to achieve and
                           programme or, as the case may be, to have achieved
                           and programmed, by reason of the Relevant Item

         and for the purpose of determining the separate amounts under (a) and
         (b), but without prejudice to the generality of the foregoing:

                           (i)      no account shall be taken of:
                           
                                    (A)   any trivial amounts;

                                    (B)  any costs, to the extent that they
                                         would have been, or would be, avoided
                                         by prudent management action taken
                                         since the transfer date (and for this
                                         purpose what constitutes "prudent
                                         management action" shall be assessed

                  which has been given at the time when the reference is made)
                  ("the Relevant Period") is most likely to allow, or, as the
                  case may be, require, the Appointee to make such charges over
                  the Relevant Period ("Adjusted Charges"), in such a manner as
                  to secure that the increase, or, as the case may be, the
                  decrease, in revenue attributable to the making of Adjusted
                  Charges would, in each year of the Relevant Period, be equal
                  to:

         (i)      the Annual Allowable Amount for that year,

         plus

         (ii)     where Base Cash Flows at Outturn Prices have occurred prior to
                  the first year of the Relevant Period, the amount, which,
                  calculated as a constant annual amount over the Relevant
                  Period, would result in the sum of the Net Present Values of
                  these amounts equaling the Sum of the Net Present Values or
                  the Annual Allowable Amounts for each of the years prior to
                  the Relevant Period.

14.      Not used.

14.4     A Reference Notice given to the Director in respect of sub-paragraph
         14.2 shall contain or be accompanied by reasonable details of the
         Relevant Item in respect of which the Reference Notice is given and,
         unless the Director otherwise consents, shall be given not later than:

         (1)      the first day of October immediately preceding the first of
                  the Charging Years in respect of which the Appointee wishes
                  the change to the Adjustment Factor to take effect; or

         (2)      if later, where the Director has given a notice to the
                  Appointee under paragraph 15(1) in respect of the same
                  Charging Year, within fourteen days from the receipt by the
                  Appointee of that notice.

15       Changes to the Adjustment Factor initiated by the Director relating to
         Notified Items and Relevant Changes of Circumstance.

         In the case of a Notified Item or where any Relevant Change of
         Circumstance has occurred or is to occur, the Director may, having
         given notice to the Appointee specifying the Notified Item or, as the
         case may be, the Relevant Change of Circumstance, of his intention so
         to do not later than:

         (1)      the first day of October immediately preceding the first of
                  the Charging Years in respect of which he proposes the change
                  to the Adjustment Factor to take effect; or

         (2)      if later, where the Appointee has given a Reference Notice to
                  the Director in respect of sub-paragraph 14.2 and falling
                  within sub-paragraph 14.4(1) in respect of the same Charging
                  Year, within fourteen days from the receipt by the Director of
                  that Reference Notice

         determine the questions set out in sub-paragraph 14.2 in respect of
         that Notified Item or, as the case may be, that Relevant Change of
         Circumstance. A single notice may be given under this paragraph 15 in
         respect of any number of Notified Items and Relevant Changes of
         Circumstance and sub-paragraph 14.2 shall be construed accordingly.

where sub-paragraph 14.4(2) or 15(2) applies, the questions set out in (5) to
(9) inclusive of sub-paragraph 14.2 shall be determined in respect of all
Notified Items and Relevant Changes of Circumstance in respect of which the
Appointee and the Director have given notice, taken as a whole.

Part V is unchanged.

Part VI.    Provision of information to the Director

18.1     The Appointee shall furnish to the Director:

         (1)      not later than 31st March immediately following the date of

                  under paragraph 10);

         (2)      not later than 30th September immediately following the date
                  of the Reference Notice (in the case of a reference under
                  paragraph 11);

         (3)      at the time when it gives the relevant Reference Notice to the
                  Director (in the case of a reference under paragraph 14
                  falling within sub-paragraph 14.4(1),

         (4)      as soon as reasonably practicable and in any event not later
                  than the expiry of one month from the date of the Director's
                  notice to the Appointee under paragraph 15 (in the case of
                  such a notice, including the case of a reference under
                  paragraph 14 falling within sub-paragraph 14.4(2))

                  such Information as the Appointee reasonably believes is
                  necessary or, as the case may be, as the Director may
                  reasonably require in his said notice, to enable the Director
                  to make his determination. The Appointee shall also furnish to
                  the Director as soon as reasonably practicable such further
                  Information as the Director may from time to time by notice to
                  the Appointee reasonably require to make his determination.

                  The remainder of Part VI is unchanged.

OFWAT PRESS NOTICE 29 MARCH 1994

- -     ALSO STOCK EXCHANGE ANNOUNCEMENT 29 MARCH 1994

OFWAT INTERFERES LESS IN CHANGING WATER COMPANIES' PRICE LIMITS

Ian Byatt, Director General of Water Services, today welcomed changes to the
licences of another 27 water and sewerage companies which will reduce the scope
and simplify the procedure for adjusting charges between Periodic Reviews -
either at the request of the company or the Director General. The changes will
reduce regulatory risk because the outcome of these Interim Determinations will
be more clear and there will be less scope for disagreement. The licence
amendments made today will come into effect from Friday 1 April.

All the companies now have agreed similar amendments with the Director General,
except for the smallest, Cholderton and District Water Company Limited.

Up until now the licence has allowed the Regulator to look at all aspects of
company business when considering adjusting price limits between Periodic
Reviews. Commenting on the changes Ian Byatt said:

         "The interests of each company and its customers are best served if
         most changes in price limits are made at five or ten yearly Periodic
         Reviews. If there is an interim adjustment, the basis for the change
         should be both clear arid certain.

         "Reducing the scope for change between Periodic Reviews provides a
         stable basis a which each company can draw up its business plans.
         Revenue will grow more steadily, investment can be more stable and
         assets can be renewed in a steady and sustainable way. Companies will
         be better placed to take advantage of technological and other
         innovations.




                                       14
<PAGE>   179



         "Where adjustments need to be made, the criteria for adjusting price
         limits have been clarified. Where adjustments are required to allow for
         new quality and environmental obligations, the new provisions will
         ensure that changes follow directly from changes in Government policy.

         "When I reset all price limits in July, I will take full account of
         these licence amendments. I will consider the risk carried by each
         company when assessing a reasonable return on capital".

The modifications to Part IV of Condition B of the Licence are:

*        to limit the scope for Interim Determinations by reducing from eight to
         three the number of "relevant changes of circumstance" which may
         trigger a Determination; 
                  Four of the companies have retained a fourth relevant change,
                  relating to changes in expenditure because national
                  construction costs are at a different level from that assumed
                  when price limits were last set.
*        to set out a procedure for notifying new legal requirements which may
         involve changes in costs;
*        to simplify and make more automatic the calculation of revised price
         limits at Interim Determinations.

Adjustments to price limits between Periodic Reviews are still possible, but
mainly take account of any unanticipated, legal requirements which may be
imposed on companies.

In addition, eight companies have deleted the provision which allows them to
ask for a change to their price limit if they suffer a substantial adverse
effect on their business. Thirteen others now have this provision as a two-way
process, so that the Director General can seek to revise price limits in
unforeseen substantially beneficial circumstances.

Price Limit adjustments at Interim Determinations will be simplified and made
more automatic by calculating them in a specified way on the basis of allocated
cost changes.

Sixteen companies retain the requirement that the Director General should, in
making Interim Determinations, also take account of the implications for the
level of interest cover until the next Periodic Review. In these cases, it will
be assumed that additional costs are between Reviews by means of borrowing
rather than by a share issue. For companies without the reference to Interest
cover, price limit adjustments will be based on a weighted average cost of
capital which will be higher than the cost of borrowing.


NOTES TO EDITORS

1        Relevant changes of circumstance retained by all companies are:

         -        the application of (or change to) any legal requirement;
         -        differences between proceeds or the sale of surplus land and
                  the proceeds which were assumed when the Adjustment Factors
                  were last set;
         -        non-achievement of a legal requirement allowed for when
                  Adjustment Factors were last revised.

         a "DISPOSAL CERTIFICATE" means a certificate signed by all the
         directors of the Appointee for the time being or approved by a duly
         convened meeting of the board of directors of the Appointee for the
         time being and signed by a director or the secretary of the Appointee
         confirming that it has been so approved and having attached to it a

         containing the resolution to approve the certificate;

         "FORMAL TENDER" means a tender, acceptance of which creates a binding
         obligation to purchase;

         "LAND" includes any interest or right in or over any land;

         "THE MATERALITY AMOUNT" for the purpose of any disposal of land

         is (pound)1 million

         or such greater amount as may from time to time be determined by the
         Director so as to allow for movements in the Retail Prices Index or as
         may from time to time otherwise be determined by the Director and
         approved by the Secretary of State;

         "NOMINEE" of any person includes any person acting at the direction
         of, or in concert with, that first-mentioned person or pursuant to any
         agreement or understanding with that first mentioned person;

         a "PROPOSED DISPOSAL" is any such disposal to which paragraphs 4, 5 or
         6 applies;




                                       18
<PAGE>   183



         "PROTECTED LAND" and "DISPOSAL" have the meanings respectively given to
         them in section 169 and cognate expressions shall be construed
         accordingly;

         "SHORT TERM DISPOSAL" means a disposal which consists of the creation
         of any interest or right in or over protected land which the Appointee
         has an unconditional right to terminate without penalty at any time and
         from time to time by not more than thirty months' notice or which
         expires or otherwise ceases in accordance with its terms within thirty
         months of the date of its creation without any other interest or right
         arising on such expiry or cessation;

         "THE TRANSFER THRESHOLD" for the purpose of any disposal of land to an
         Associated Company is

         (pound)500,000

         or such greater amount as may from time to time be determined by the
         Director so as to allow for movements in the Retail Prices Index or as
         may from time to time otherwise be determined by the Director and
         approved by the Secretary of State;

         "VALUE" includes value of any kind including, without limitation, cash,
         the value of real or personal property or any interest in such property
         and the value of any right or benefit, actual or prospective, and the
         value of any release, in whole or in part, of any obligation or claim.

2.2      For the purpose of calculating "best price":

         (1)      for the purpose of any valuer's certificate required to be
                  furnished under sub-paragraph 4.6(1)(a)(i), or 5.1(1)(b);

                  (a)      no reduction shall be made on account of the method,
                           terms and timing of the proposed disposal (if
                           relevant) in respect of which the relevant
                           certificate is required to be furnished, but "best
                           price" shall be calculated on the basis of a disposal
                           of the land in question, the method, terms and timing
                           of which are most likely to secure that the best
                           price is obtained; and

                  (b)      where the proposed disposal or, as the case may be,
                           the change of use is related to, or connected or
                           interdependent with, any other proposed disposal,
                           then, subject to subparagraph (a), no account shall
                           be taken of that fact; and

         (2)      for any purpose under this Condition, "best price" shall
                  include value of any kind as "value" is defined in
                  sub-paragraph 2.1.

3.       "RING FENCING"

3.1      The Appointee shall at all times ensure, so far is reasonably
         practicable, that if a special administration order were made in
         respect of the Appointee the Appointee would have available to it
         sufficient rights and assets (other than financial resources) to enable
         the special administrator so to manage the affairs, business and
         property of the Appointee that the purposes of




                                       19
<PAGE>   184

         such order could be achieved, provided that this paragraph shall not
         require the Appointee to seek to re-negotiate the terms of any
         contract or obligation which, in accordance with a scheme under
         Schedule 2, is transferred to the Appointee.

3.2      The Appointee shall publish with its audited accounts for each
         financial year a statement as to whether the Appointee was in

3.3      Where any such rights and assets as are mentioned in sub-paragraph 3.1
         are provided or made available by any Group Company, the Appointee's
         obligations under sub-paragraph 3.1 in respect of such rights and
         assets shall be such as they would be if the words "so far as
         reasonably practicable" and the proviso were omitted from that
         sub-paragraph.

3.4      The state, condition and capacity of assets used by the Appointee in
         the Appointed business are the subject of Conditions J and L and
         accordingly sub-paragraph 3.1 shall not apply thereto.

         tender or to Associated Companies

4.1      Subject to sub-paragraph 4.2, the Appointee shall not make any

         have complied with the provision of sub-paragraph 4.3.

4.2      Sub-paragraph 4.1 shall not apply:

         (1)      to any Short-term Disposal;

         (2)      to any disposal of any protected land the value of
                  which, when aggregated with:

                  (a)      the value of any other protected land which
                           affects or might affect the value of such
                           protected land or the value of which is or
                           might be affected by such protected land;
                           and

                  (b)      to the extent not taken into account under
                           (a) the value of any other protected land
                           the subject of any other disposal which has
                           taken place, is proposed or contemplated and
                           which in the honestly held and reasonable
                           opinion of the Appointee is or might be
                           related to, or connected or interdependent
                           with, the first mentioned disposal
                           does not exceed the Materiality Amount;

         (3)      to any such disposal of protected land as is referred
                  to in paragraphs 5 and 6;

         (4)      to any disposal of any protected land made in
                  accordance with any such provision as is referred to
                  in section 152(5(a) to the relevant person referred
                  to in that section; or

         (5)      to any disposal of any protected land made pursuant
                  to any obligation entered into by the Water Authority
                  prior to the transfer date.

                  proposed disposal, furnish to the Director a Disposal

                  (a)      identifies the protected land the subject of the

                                    having made due and careful enquiry, any

         a valuer appointed by the Appointee ("THE VALUER") addressed to the
         Director which states that in the opinion of the Valuer the
         consideration certified under sub-paragraph 4.3(1)(g)(iii) is the best
         price that could reasonably be obtained for the protected land in
         question, having regard to all the circumstances at the time when the
         certificate is given (including, but without limitation, any reasonable
         prospect of planning permissions being obtained).

                                    Appointee from the proposed disposal is the
                                    best price likely to be obtained from a
                                    disposal of the land in question to an

                                    planning permissions being obtained); and

                           (B)      the amount of the consideration to be
                                    received or expected to be received by the
                                    Appointee from the proposed disposal,
                                    expressed in cash according to when that
                                    consideration is to be, or is expected to be
                                    received; and

         (2)      shall furnish to the Director in writing such further
                  information regarding the proposed disposal which the Director

                  are in accordance with any terms which may have been specified
                  by the Director, either in relation to disposals of protected
                  land to Associated Companies generally or in relation to the
                  particular proposed disposal, being such terms as the Director
                  considers appropriate to secure that the Appointee receives
                  such share of any value to be derived or expected to be
                  derived by the Associated Company from the land in question as
                  the Director considers appropriate, having regard to the duty
                  imposed on the Director under section 7(3)(c).

6.4      In any case where the full confirmation required by (f) of
         sub-paragraph 4.3(1) cannot properly be given the Appointee shall not
         enter into a relevant obligation unless the prior written consent of
         the Director to the proposed disposal has been obtained, such consent
         not to be unreasonably withheld or delayed.

7.       Disclosure of Information to Valuers

         The Appointee shall disclose to the Valuer appointed for the purpose of
         any provision of this Condition all Information which, in the
         reasonable opinion of the Appointee, has or is likely to have a
         material bearing on the Valuer's certificate to be given under that
         provision and such other Information as the Valuer may reasonably
         require to enable him to give his certificate.

                        MODIFICATION OF THE CONDITIONS OF
                                 APPOINTMENT OF
                            WESSEX WATER SERVICES LTD

The following condition shall be inserted into the Appointment.

"Condition Q:  Interruptions in Supply because of Drought

1.       Interpretation

         "business customer" means the person who is liable to pay the
         Appointee's charges in respect of a supply of water to premises other
         than domestic premises;

         "drought order" means an order made under section 73 of the Water
         Resources Act 1991;

         "household customer" means the person who is liable to pay the
         Appointee's charges in respect of a supply of water to domestic
         premises.

2.       Liability and amounts of payments

2.1      Where a supply of water to premises is interrupted or cut off under the
         authority of a drought order the Appointee shall, subject to
         sub-paragraph 2.2, pay to the customer (or credit to his account)
         whichever of the amounts referred to in paragraph 3 is applicable.

2.2      The Appointee shall not be liable to make any payments under this
         Condition where the circumstances were so exceptional that it would
         have been unreasonable to have expected the interruption or cut-off to
         have been avoided.

3.       Amounts payable to household and business customers

3.1.1    The Appointee shall pay to a household customer(pound)10 for each day
         during which (or during part of which) the supply is interrupted or cut

<PAGE>   192



3.1.2    The amount payable to any household customer in any Charging Year shall
         not exceed the average amount of water charges payable to the Appointee
         by household customers for the Charging Year preceding that in which
         the interruption or cut-off happens.

3.2.1    The Appointee shall pay to a business customer(pound)50 for each day
         during which (or during part of which) the supply is interrupted or cut
         off.

3.2.2    The amount payable to any business customer in any Charging Year shall
         not exceed -

         (a)      the amount of water charges payable by that customer for the
                  supply of water to those premises for the Charging Year
                  preceding that in which the interruption or cut-off happens or

         (b)      if that customer was not liable to pay those charges,
                  (pound)500.

3.2.3    When calculating the charges payable by a business customer for the
         supply of water services, amounts payable in respect of any separate
         supply which was provided solely for purposes other than domestic
         purposes shall be excluded.

3.3      If, when a payment becomes due under this Condition, a customer owes
         money to the Appointee and the debt has been outstanding for more than
         6 weeks, any payment frpm the Appointee to which the customer is
         entitled under this Condition shall, to the extent that it does not
         exceed the amount so owed, be made by way of credit to that customer's
         account.

4.       Determination of Disputes

4.1      Where any dispute arises between the Appointee and a customer as to the
         right of that customer to a payment or credit under this Condition, the
         matter may be referred to the Director by either party for
         determination(1).

4.2      Any determination under this Condition shall be final and, fails to
         give effect to the determination, the customer amount in question
         against any payment which is due to the Appointee.





- --------------------------
         (1) An explanatory note, which is not part of the Condition, is 
             attached.

5.       Cessation or Modification of this Condition

5.1      This Condition shall cease to have effect in relation to any
         interruptions or cut-offs occurring on or after the commencement date
         of any Regulations made by the Secretaries of State pursuant to Section
         38 of the Water Industry Act 1991, implementing the recommendations
         made to them by the Director in May 1996 for the making of payments to
         customers for interruptions or cut-offs because of drought.

5.2      If the Regulations referred to in sub-paragraph 5.1 relate to either
         household customers or business customers only, this Condition shall
         cease to have effect in so far as it relates to those customers."

to make a payment under paragraph 4 of Condition Q he will, while not being able
to anticipate all relevant circumstances, take account of the following:

                  those resources, including the exploration of new resources;

         (b)      the promotion by the company of the efficient use of water by
                  its customers;

                  order containing the provision authorised by paragraph (b) of
                  section 74(2) of the Water Resources Act 1991 (non-essential
                  use); and

                            OFFICE OF WATER SERVICES

                   WATER INDUSTRY ACT 1991 SECTIONS 13 AND 14
           PROPOSALS BY THE DIRECTOR GENERAL OF WATER SERVICES FOR THE
                MODIFICATION OF THE CONDITIONS OF APPOINTMENT OF
                            WESSEX WATER SERVICES LTD



The process

Wessex Water Services Ltd (Wessex Water) is a wholly-owned subsidiary of Wessex
Water plc (Wessex). Enron Water (Europe) PLC is owned by Enron Corp (Enron). As
a condition of the takeover of Wessex Water by Enron Water (Europe) PLC, Enron
has agreed to the modification of the conditions of appointment of Wessex Water
as a water and a sewarage undertaker.

Any representation about, or objection to, these proposals must be in writing
and sent to the Director General of Water Services, Centre City Tower, 7 Hill
Street, Birmingham B5 4UA (Fax 0121 625 3606) so as to be received by him not
later than 5:00 PM on Friday 27 November 1998. Please quote reference LEG34/4.

EXPLANATION OF THE PROPOSED MODIFICATIONS AND THE REASONS FOR THEM

MAINTENANCE OF COMPARISONS WITH OTHER WATER AND SEWARAGE UNDERTAKERS.

The Director General of Water Services (the Director) believes that the
modifications are necessary to enable him to continue to gather information
about how Wessex Water carried out its statutory functions and the costs which
it incurs, after Wessex becomes part of the Enron Group. The modifications will
therefore -

1.(a)    prohibit payment to any Associated Company in respect of any Charging
         Year of any amount on account of services received by Wessex Water from
         that company which exceeds:

                  (i)      the prices ascertained from market testing carried
                           out by Wessex Water in accordance with arrangements
                           previously approved by the Director and which have no
                           prejudicial effect on the proper carrying out of
                           Wessex Water's functions; or

                  (ii)     if, in the opinion of the Director, market testing is
                           not appropriate, then such proportion of the costs
                           (including a reasonable return) actually incurred by
                           the Associated Company as the Director agrees is
                           appropriate; and



                                       8
<PAGE>   199




   (b)   require Wessex Water to obtain from the Associated Company information
         required by the Director about the latter's costs.

RING-FENCING OF THE ASSETS OF WESSEX WATER AND ITS ABILITY TO ACT SEPARATELY
FROM ENRON OR ANY INTERMEDIATE PARENT COMPANY.

At the same time, the Director wishes to ensure that Wessex Water's licensed
business is ring-fenced from other activities of the Enron Group. Wessex Water
must not, whether through its involvement in those other group activities or by
its dividend policy, put at risk its ability either to carry out its functions
as a water and a sewerage undertaker or to finance them. Further modifications
will therefore -

2.       prohibit the transfer of any asset from Wessex Water to any Associated
         Company except with the Director's consent and in compliance with his
         requirements concerning the valuation of the asset and its treatment in
         Wessex Water's accounts;

3.       prohibit Wessex Water from:

         (i)      giving any guarantee of any liability of any company within
                  the Enron Group;

         (ii)     making to any such company any loan;

         (iii)    continuing or assuming any commitment which includes a
                  cross-default obligation (whereby Wessex Water's financial
                  liabilities are increased or accelerated because of default
                  elsewhere within the Enron Group)

         without the Director's consent; and

4.       require that Wessex Water's dividend policy will not, in the opinion of
         the Director, impair its ability to finance the proper carrying out of
         its functions.

The directors of Wessex Water are already required to certify annually to the
Director that the company has adequate financial and management resources.
Further modifications will require -

5.       (i)      Wessex Water to inform the Director as soon as its Board
                  becomes aware of any circumstance which causes the Board to
                  believe that its most recent annual certificate of adequacy of
                  its financial and management resources could not be repeated
                  in the light of those circumstances;

         (ii)     that every annual certificate referred to in i) shall be
                  accompanied by a report prepared by Wessex Water's




                                       9
<PAGE>   200



         Auditors and addressed to the Director, stating whether they
         are aware of any inconsistencies between, on one hand, that
         certificate and the statements submitted with it and, on the
         other hand, any information which they obtained during their
         work as Wessex Water's Auditors; and

         (iii)    that the directors record their opinion that all contracts
                  entered into with any Associated Company include all necessary
                  provisions and requirements concerning the standard of service
                  to be provided to Wessex Water to ensure that it is able to
                  meet all its obligations as a water and a sewerage undertaker.

Although Wessex Water is, and will continue to be, a subsidiary, it has its own
duties as the water and the sewerage undertaker for the areas of those
Appointments. The Director considers it important that Wessex Water should, in
carrying out those functions, behave as if they were substantially its sole
business and it were a separate public limited company. Further modifications
will require -

6.       that Wessex Water shall, at all times, conduct the Appointed Business
         as if it was substantially Wessex Water's sole business and Wessex
         Water was a separate public limited company. In doing so, Wessex Water
         should have particular regard to the following:

         (a)      the competition of Wessex Water's Board should be such that
                  its directors, acting as such, act independently of Enron and
                  any intermediate parent company;

         (b)      Wessex Water must ensure that each such of its directors must
                  disclose, to it and to the Director, conflicts between their
                  duties to Wessex Water and other duties;

         (c)      where potential conflicts exist between the interests of
                  Wessex Water as a water and a sewarage undertaker and those of
                  other companies in the Enron Group, Wessex Water and its
                  directors must ensure that, in acting as directors of Wessex
                  Water they have regard exclusively to the interests of Wessex
                  Water as a water and a sewerage undertaker;

         (d)      no director of Wessex Water should vote on any contractor any
                  arrangement or any other proposal in which he has an interest
                  by virtue of other directorships. This arrangement should be
                  reflected in Wessex Water's Articles of Association;



                                       10
<PAGE>   201




         (e)      Wessex Water should inform the Director without delay when:

                  (i)      a new director is appointed;

                  (ii)     the resignation or removal of a director takes
                           effect; or

                  (iii)    any important change in the functions or executive
                           responsibilities of a director occurs.

Wessex Water should notify the Director of the effective date of the change and,
in the case of an appointment, whether the position is executive or
non-executive and the nature of any specific function or responsibility.

         (f)      the dividend policy adopted by Wessex Water in the light of
                  proposal 4 (above); and

                  legally-enforceable undertaking in Wessex Water's favour and
                  in a form specified by the Director, that it will:

                  (i)      refrain from any action which would be likely to
                           cause Wessex Water to breach any of its obligations
                           under the Water Industry Act 1991 or the conditions
                           of its appointments as a water and a sewerage

                           customers

         (b)      require all terms of that undertaking to apply to all other
                  companies within the Enron Group;

                  Wessex Water holds its Appointments as a water and a sewerage
                  undertaker (or either of them) and remains a member of the
                  Enron Group; and

         (d)      require the undertaking to be delivered to the Director not
                  later than 21 days after this modification comes into force;

11.      require Wessex Water to -

                  (i)      produce to the Director the original of the
                           undertaking under 9 above and provide him with any
                           certified copies which he requires; and

                  (ii)     inform the Director immediately in writing, if it
                           becomes aware that the undertaking has ceased to be
                           legally-enforceable, or that there has been any
                           breach of its terms; and

12.      prohibit Wessex Water (except with the Director's consent) from making
         any contract with a member of the Enron Group which is not one of the

notice to the Lender, prepay the Loan, in whole or in part (but, if in part, in
a minimum amount of (pound)5,000,000 and an integral multiple of
(pound)1,000,000), together with all accrued and unpaid interest hereunder and
all fees, costs, or expenses, if any, then due and payable. Any prepayment
hereunder is subject to Clause 16 (Indemnities).

5.2      ADDITIONAL RIGHT OF PREPAYMENT AND CANCELLATION

If the Company is required to pay any amount to the Lender under Clause 9
(Taxes), the Company may, whilst the circumstances giving rise to the
requirement continue, serve a notice of prepayment and cancellation on the
Lender. In this event on the date falling 5 Business Days after the date of
service of the notice, the Company shall prepay the Loan in full together with
all other amounts payable by it to the Lender under this Agreement.

5.3      MITIGATION

If circumstances arise which would, or would on the giving of notice, result in:

(a)      any additional amounts becoming payable under Clause 9.1 (Gross-up); or

(b)      any prepayment or cancellation under Clause 10 (Illegality),

then, without limiting the obligations of the Company under this Agreement and
without prejudice to the terms of Clauses 9.1 (Gross-up) and 10 (Illegality),
the Lender shall, at the request of, and in consultation with, the Company, take
such reasonable steps as may be open to it to mitigate or remove the relevant
circumstance, unless to do so might (in the opinion of the Lender) have a
material adverse effect on its business, operations, or financial condition or
be contrary to its banking policies or be otherwise prejudicial to it, and
provided that the Company pays any costs incurred by the Lender in connection
with such mitigation or removal.

         and shall not demand payment under Clause 5.4(a), unless the assignment
         pursuant to the Acceptable Offer is not timely consummated in
         accordance with its terms. If an Acceptable Offer and the assignment
         pursuant thereto are timely made and consummated in accordance with the
         terms of such Acceptable Offer, then all of Clauses 11 (Representations

         deleted from this Agreement. If an Acceptable Offer and the assignment

9.       TAXES

9.1      GROSS-UP

(a)      All payments by the Company hereunder (and all payments from the Azurix
         Europe Interest Account (Sterling) , as defined in the Indenture, and
         the Azurix Europe Note Proceeds Account (Sterling) as defined in the
         Indenture) shall be made without any deduction and free and clear of
         and without deduction for or on account of any taxes or other
         deductions, except to the extent that such deduction is required by law
         to make payment subject to any taxes. If any tax or amounts in respect
         of tax must be deducted, or any other deductions must be made, from any
         amounts payable or paid by the Company hereunder (or any payments from
         the Azurix Europe Interest Account (Sterling) and the Azurix Europe
         Note Proceeds Account (Sterling)), the Company shall pay such
         additional amounts as may be necessary to ensure that the Lender
         receives a net amount equal to the full amount which it would have
         received had payment not been made subject to such deduction.

(b)      The Company agrees to notify the Lender promptly if it becomes aware
         that sub-clause 9.1(a) applies.

9.2      TAX RECEIPTS

All taxes required by law to be deducted or withheld by the Company from any
amounts paid or payable hereunder shall be paid by the Company when due and the
Company shall, within 15 days of the payment being made, deliver to the Lender
evidence satisfactory to the Lender (including all relevant tax receipts, if
available) that the payment has been duly remitted to the appropriate authority.

9.3      REFUND OF TAX CREDITS

If:

(a)      the Company makes a payment under Clause 9.1 (Gross-up) (a "TAX
         PAYMENT") in respect of a payment to the Lender hereunder; and

(b)      the Lender determines in good faith that it has obtained a refund of
         tax or obtained and used a credit against tax on its overall net income
         (a "TAX CREDIT") which the Lender is able to identify in good faith as
         attributable to that Tax Payment,

then, if it determines, acting in good faith, that it can do so without any
other adverse consequences for itself, the Lender shall forthwith reimburse the
Company such amount as the Lender in its absolute discretion determines to be
such proportion of that Tax Credit as will leave the Lender (after that
reimbursement) in no better or worse position in respect of its worldwide tax
liabilities than it would have been in if no Tax Payment had been required. The
Lender shall have an absolute discretion as to whether to claim any Tax Credit
(and, if it does claim, the extent, order and manner in which it does so) and
whether any amount is due from it under this Clause 9.3 (Refund of tax




                                      -22-
<PAGE>   27

credits) (and, if so, what amount and when). The Lender shall not be obliged to
disclose any information regarding its tax affairs and computations. If the
Lender reimburses the Company pursuant to this Clause 9.3 (Refund of tax
credits) and the Lender subsequently determines that the Tax Credit was not
available or has been withdrawn or that it was unable to use the Tax Credit in
full, the Company shall reimburse the Lender such amount (not exceeding the
amount originally reimbursed by the Lender) as is necessary to place the Lender
in the same after-tax position as it would have been in if the Tax Credit had
been obtained and fully used by the Lender.

9.4      DOUBLE TAXATION RELIEF

(a)      The Lender shall (if it is able to do so and if permitted by law) as
         soon as reasonably practicable after the date of this Agreement (or any
         assignment thereof) deliver to the Company a duly completed form from
         the relevant tax authorities such that the Company may apply to the
         Inland Revenue for a direction under the Double Taxation Relief (Taxes
         on Income) (General) Regulations 1970 that the Company shall, on
         account of the relevant Double Taxation Treaty, pay any interest due to
         the Lender hereunder without deduction of U.K. tax. The Lender shall,
         upon the reasonable request of the Company, promptly and duly (if it is
         able to do so and if permitted by law)) execute and deliver any and all
         such further instruments and documents which the Company has determined
         are required for the purpose of obtaining such a direction.

(b)      The Company will not be liable to pay to the Lender under Clause 9.1
         (Gross-up) any amount in respect of taxes levied or imposed by the U.K.
         or any taxing authority of or in the U. K. which it would not have been
         obliged to pay if the Lender had performed its obligations under
         paragraph (a) above to provide the forms and other instruments and
         documents specified therein; provided that the Lender shall be deemed
         to have performed its obligations under paragraph (a) above, unless,
         notwithstanding the Company's preparation, completion (to the extent of
         the Company's knowledge of the relevant facts), and delivery of all
         such forms, instruments and documents required to be executed and
         delivered by the Lender or any Permitted Assignee, the Lender or any
         Permitted Assignee fails to execute and deliver such forms,
         instruments, and documents.

10.      ILLEGALITY

If it is or becomes unlawful or contrary to any regulation in any jurisdiction
for the Lender to give effect to any of its obligations as contemplated by this
Agreement or to fund or maintain its participation in the Loan, then:

(a)      the Lender shall promptly notify the Company accordingly; and

(b)      the Company shall, on the latest day permitted by the relevant law or
         regulation, prepay the Loan together with all other amounts payable by
         it to the Lender under this Agreement.

14.      EXPENSES

14.1     INITIAL AND SPECIAL COSTS

The Company shall promptly on demand pay to the Lender the amount of all
reasonable costs and expenses (including legal fees and any related
irrecoverable value added tax) reasonably incurred by it in connection with any
amendment, waiver, consent or suspension of rights (or any proposal for any of
the foregoing) requested by or on behalf of the Company and relating to this
Agreement.

14.2     ENFORCEMENT COSTS

The Company shall forthwith on demand pay to the Lender the amount of all
reasonable costs and expenses (including, without limitation, legal fees and any
related irrevocable value added tax) incurred by it in connection with the
enforcement of, or the preservation of any rights, under this Agreement.

15.      STAMP DUTIES

The Company shall pay and forthwith on demand indemnify the Lender against any
liability it incurs in respect of any stamp, registration and similar tax or
duty which is or becomes payable in connection with the entry into, performance
or enforcement of this Agreement.

16.      INDEMNITIES

16.1     CURRENCY INDEMNITY

(a)      If the Lender receives an amount in respect of the Company's liability
         hereunder in, or if that liability is converted into a claim, proof,
         judgement or order in, a currency other than the currency (the
         "CONTRACTUAL CURRENCY") in which the amount is expressed to be payable
         hereunder:

         (i)      the Company shall indemnify the Lender as an independent
                  obligation against any loss or liability arising out of or as
                  a result of the conversion;

         (ii)     if the amount received by the Lender, when converted into the
                  contractual currency at a market rate in the usual course of
                  its business, is less than the amount owed in the contractual
                  currency, the Company concerned shall forthwith on demand pay
                  to the Lender an amount in the contractual currency equal to
                  the deficit; and

         (iii)    the Company shall pay to the Lender on demand any exchange
                  costs and taxes payable in connection with any such
                  conversion.

(b)      The Company waives any right it may have in any jurisdiction to pay any
         amount hereunder in a currency other than that in which it is expressed
         to be payable.

16.2     OTHER INDEMNITIES

The Company agrees, to the fullest extent permitted by law, to indemnify and
hold harmless the Lender and each of its Permitted Assignees, and each of the
directors, officers, employees and agents of any of them from and against any
and all claims, damages, liabilities and expenses (including, without
limitation, reasonable fees and disbursements of counsel and claims, damages,
liabilities and expenses relating to environmental matters) for which any of
them may become liable or which may be incurred by or asserted against the
Lender or such Permitted Assignee or the director, officer, employee or agent of
any of them in each case in connection with or arising out of or by reason of
any investigation, litigation, or proceeding, arising out of, relating to or in
connection with this Agreement or any transaction in which any proceeds of all
or any part of the Loan are applied (expressly including any such claim, damage,
liability or expense attributable to the ordinary, sole or contributory
negligence of such indemnified party, but excluding any such claim, damage,
liability or expense attributable to the gross negligence or willful misconduct
of such indemnified party). It is the intent of the parties hereto that the
Lender and each of its Permitted Assignees and the directors, officers,
employees and agents of any of them, shall, to the extent provided in this
Clause 16.2, (Other indemnities) be indemnified for their own ordinary, sole or
contributory negligence.

17.      CHANGES TO THE PARTIES

17.1     TRANSFERS BY THE COMPANY

The Company may not assign, transfer, novate or dispose of any of, or any
interest in, its rights and/or obligations under this Agreement.

17.2     TRANSFERS BY THE LENDER

The Company hereby expressly acknowledges and consents to the assignment by
Bristol of its rights under this Agreement to Marlin and the assignment by
Marlin of its rights under this Agreement to the Marlin Indenture Trustee
pursuant to the Deeds of Assignment, and acknowledges and consents to the pledge
by Bristol of its rights hereunder to Marlin pursuant to the Bristol Water
Security Agreement, dated as of the date hereof between Bristol and Marlin and
the pledge by Marlin of certain of its rights hereunder to the Marlin Indenture
Trustee (together with Marlin, "Permitted Assignees") as contemplated in the
Indenture. All references to the "Lender" hereunder shall be deemed to include
such Permitted Assignees so long as the Deeds of Assignment and the Indenture
are in effect.

17.3     INCREASED COSTS, ETC.

If:

(a)      the Lender assigns, transfers or novates any of its rights and/or
         obligations hereunder without the prior consent of the Company; and

                                      -39-
<PAGE>   44

(b)      as a result of circumstances existing at the date the assignment,
         transfer, novation or change occurs, the Company would be obliged to
         make a payment to the transferee under Clause 9 (Taxes)

then, notwithstanding the provisions of Clause 9 (Taxes), the transferee is only
entitled to receive payment under those Clauses from the Company to the same
extent as the transferor would have been if the assignment, transfer, novation
or change had not occurred.

18.      DISCLOSURE OF INFORMATION

(a)      Bristol may disclose to any Permitted Assignee:

         (i)      a copy of this Agreement; and

         (ii)     any information which Bristol has acquired under or in
                  connection herewith,

so long as such Permitted Assignee agrees not to disclose such information to
any person, other than (i) the holders of the Marlin Senior Notes requesting
such information, in the case of the Marlin Indenture Trustee, and (ii) the
holders of the Marlin Certificates requesting such information, in the case of
Marlin, in each case, upon prior receipt by such Permitted Assignee of a
confidentiality agreement executed by the holder of the Marlin Senior Note or
Marlin Certificate requesting such information, in the form attached as Schedule
I hereto.

19.      SEVERABILITY

If a provision of this Agreement is or becomes illegal, invalid or unenforceable
in any jurisdiction, that shall not affect:

(a)      the legality, validity or enforceability in that jurisdiction of any
         other provision of this Agreement; or

(b)      the legality, validity or enforceability in other jurisdictions of that
         or any other provision of this Agreement.

20.      COUNTERPARTS

same effect as if the signatures on the counterparts were on a single copy of
this Agreement.

Each Party shall indemnify the other Party against any loss or liability which
such other Party incurs as a result of such other Party accepting and/or acting
upon any notices hereunder received by such other Party from the first Party by
facsimile and which may not have been incurred if, at the time of receipt, such

22.      GOVERNING LAW

creating any liability on Wilmington Trust Company, individually or personally,
to perform any covenant, either express or implied, contained herein, all such
liability, if any, being expressly waived by the parties hereto and by any
person claiming by, through or under the parties hereto, (d) under no
circumstances shall Wilmington Trust Company be personally liable for the
payment of any indebtedness or expenses of Bristol or Marlin, as Lender or a
