100,000-for-1 common stock split effective February 2, 1999.
 
                                  AZURIX CORP.
 
   
     Azurix Corp. is a global water company engaged in the business of
acquiring, owning, operating and managing water and wastewater assets, providing
water and wastewater related services and developing and managing water
resources. Enron Corp., one of the world's leading integrated natural gas and
electricity companies, formed Azurix on January 29, 1998 to pursue opportunities
in the global water industry. Azurix's first significant step was to acquire
Wessex, a water and wastewater company based in southwestern England, for $2.4
billion on October 2, 1998. Wessex was recognized in December 1998 by the Office
of Water Services, the industry regulator, as the most efficiently operated
water and wastewater company in England and Wales.
    
 
   
     Our asset portfolio also includes interests in long-term water concessions
in the Province of Mendoza, Argentina and in Cancun, Mexico. In addition, we
acquired Philip Utilities Management Corporation, a water and wastewater
services company with operations in the United States and Canada on May 18, 1999
for $106.3 million. On May 18, 1999, we were notified that, subject to final
confirmation, we will be awarded an interest in long-term water and wastewater
concessions in two regions of the Province of Buenos Aires, Argentina, at an
aggregate price of $438.6 million. We have made each of these investments
through one or more subsidiaries, which will be our approach as we pursue our
worldwide growth strategy.
    
 
   
     On a pro forma basis, as adjusted for the offering, assuming the Wessex
acquisition occurred on January 1, 1998, and including Mendoza from the date of
our investment, but excluding the Cancun, Philip Utilities and Buenos Aires
transactions, we had operating revenues of $464.2 million, EBITDA of $298.1
million and net income of $91.1 million for the year ended December 31, 1998. As
of March 31, 1999, on a pro forma basis as adjusted for the offering, Azurix had
total assets of $3,544.4 million. To date, all of our operating revenues have
come from Wessex, and substantially all of our operations have been conducted by
Wessex.
    
 
   
     We are aggressively pursuing additional water and wastewater transactions
in Europe, North America, Latin America, the Caribbean, the Middle East, Africa,
Asia and the Pacific Rim. These include upcoming concessions in Berlin, Germany
and Santiago, Chile as well as other upcoming privatizations identified in this
prospectus and various privately negotiated transactions. We are also
continually evaluating potential acquisitions of companies owning water and
wastewater assets or providing water related services. The timing, size and
success of any of these potential acquisitions cannot be predicted.
    
 
   
     Our experienced management team from Enron, Wessex and other multinational
companies competitively positions us to capture opportunities in the global
water industry. We are transferring to our water business the skills that Enron
has successfully applied in developing global energy infrastructure projects and
the skills that our executives from Wessex and other companies have successfully
used in operating and managing water and wastewater assets.
    
 
                           THE GLOBAL WATER INDUSTRY
 
     The global water industry includes the collection, treatment, storage and
supply of drinking water, and the collection, treatment and disposal of
wastewater and its by-products. Public (municipal and other governmental) and
private (non-governmental) water companies serve industrial, commercial and
residential customers. Azurix estimates that the global water industry has total
annual revenues of approximately $300 billion. In addition, Azurix estimates
that over $600 billion will be spent on worldwide water and wastewater
infrastructure over the next decade.
 
                                        1
<PAGE>   7
 
   
     We believe that significant business opportunities exist for private sector
participation in the global water industry, including 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. Factors creating these business opportunities include:
    
 
     - Governments and industrial companies are recognizing that transferring
       ownership, operation or management of water and wastewater assets to
       experienced private parties, called outsourcing, is often more efficient
       and cost-effective than owning or operating these assets themselves.
 
   
     - Major capital investment and efficiency improvements are necessary to
       meet higher water quality and environmental standards, to connect growing
       populations to water and wastewater systems and to replace aging
       infrastructure.
    
 
   
     - Increasing demand for water resources is focusing efforts on water
       resource development and management, including efficient extraction,
       management, storage and transport of water resources.
    
 
   
     - Ownership of water and wastewater assets is highly concentrated in the
       public sector, and governments often lack the budgetary capacity and
       technical expertise needed to address efficiency, water quality and
       infrastructure improvement issues effectively.
    
 
   
                           OUR COMPETITIVE STRENGTHS
    
 
     We have several competitive strengths that should enable us to compete
successfully in the global water industry:
 
   
     - EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAMS. Although Azurix
       was recently formed, we have a group of experienced managers from
       long-established companies, including Enron, Wessex and other
       multinational companies. Our management team has extensive experience in
       competing for, developing and operating infrastructure projects worldwide
       and in managing water and wastewater companies in the United Kingdom and
       the United States. Our senior executives are complemented by a group of
       experienced business developers who identify opportunities in the global
       water industry. Since our formation, we have qualified for bidding on
       privatizations in Europe, Latin America and the Middle East. Of the 14
       privatizations in which we have actively participated, only one final
       award has been made. In this bid for the concession in Valparaiso, Chile,
       we were second to the winning bidder. We recently were notified that,
       subject to formal confirmation, we will be awarded an interest in
       long-term water and wastewater concessions in two regions of the Province
       of Buenos Aires, Argentina. We are also currently one of three finalists
       for the partial privatization of the Berlin, Germany water and wastewater
       system. In addition, we successfully identified and closed the privately
       negotiated Cancun and Philip Utilities transactions.
    
 
   
     - WESSEX OPERATING EXPERIENCE AND TECHNICAL EXPERTISE. From Wessex, we have
       obtained the operating experience, research skills and technical
       expertise necessary to evaluate potential water projects, to qualify for
       bidding on water projects 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 should allow us
       to more accurately assess the regulatory risks and opportunities
       presented by the projects we evaluate.
    
 
   
     - FINANCING EXPERTISE. Members of our management team have experience using
       sophisticated financing and capital raising techniques in both global and
       local markets to lower the cost of capital for the financing of projects
       and acquisitions. As our portfolio grows and matures, we intend to
    
                                        2
<PAGE>   8
 
   
       enhance our equity returns and reduce our overall risk exposure through
       opportunistic sales of all or a portion of our individual assets or
       investments that have appreciated in value.
    
 
                             OUR BUSINESS STRATEGY
 
     Our business strategy is focused on three complementary areas in the global
water industry:
 
   
     - ACQUIRING, OWNING, OPERATING AND MANAGING WATER AND WASTEWATER ASSETS. We
       intend to build a diversified portfolio of water and wastewater assets,
       including both established businesses with stable returns and concessions
       and projects in emerging markets with significant development
       requirements and potential for growth and enhanced returns. We intend to
       acquire water and wastewater assets through participation in public
       tenders and privately negotiated transactions throughout the world.
       Following an acquisition of water or wastewater assets, we plan to
       increase revenues by expanding customer bases and services and improving
       the accuracy and timing of billing and collection procedures. In
       addition, we intend to grow operating income by reducing operating costs,
       prioritizing and managing capital expenditures, increasing efficiency and
       applying sophisticated financing techniques.
    
 
   
     - PROVIDING WATER AND WASTEWATER RELATED SERVICES. We intend to provide a
       broad range of services to municipal and industrial customers around the
       world, including:
    
 
      -- Operations, management and engineering -- services to design, build,
         operate or maintain water and wastewater assets
 
      -- Residuals management -- services to dispose of wastewater and biosolids
         that result from wastewater treatment
 
      -- Underground infrastructure remediation and development -- services to
         repair and replace water and wastewater distribution and collection
         systems
 
     - DEVELOPING AND MANAGING WATER RESOURCES. We intend to pursue
       opportunities in water resource development and management and address
       the capital, technical and operational needs in this area of the water
       industry.
 
   
     By pursuing our business strategy in these three areas, we plan to offer a
full spectrum of services to meet our customers' water and wastewater needs. We
are continually evaluating potential acquisitions of water and wastewater
assets, companies and water service providers. In evaluating potential
investments, we plan to follow a disciplined approach focused on identifying
potential for increased returns, analyzing the impact on tariffs and revenues of
the future regulatory regime and assessing the relevant risks related to each
transaction. We believe this approach will allow us to identify and compete
successfully for those water and wastewater projects offering attractive rates
of return.

                          AZURIX'S CORPORATE STRUCTURE
 
   
     The following chart illustrates our corporate structure after the offering
and assumes the underwriters' over-allotment option will not be exercised. This
chart does not show our complete corporate structure and should be read in
conjunction with the more detailed descriptions contained elsewhere in this
prospectus.
    
                                    [CHART]
 
              ATLANTIC WATER TRUST'S OWNERSHIP INTEREST IN AZURIX
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately 68.7% of our outstanding common stock, 64.1% if the underwriters'
over-allotment option is exercised in full. Each of Enron and Marlin Water Trust
owns a 50% voting interest in Atlantic Water Trust. To date, Enron has appointed
all of the directors of Atlantic Water Trust and Azurix, although Marlin Water
Trust at any time has the right to elect or replace half of the directors of
Atlantic Water Trust and currently up to half of the Azurix directors. Following
the offering, as long as Atlantic Water Trust owns a majority of our outstanding
voting 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 voting stock held by persons other than Atlantic Water
Trust, Enron and its affiliates. Furthermore, Marlin Water Trust, with the
consent of the holders of a majority of our outstanding voting 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.
In each case, Marlin Water Trust's right to designate directors shall be reduced
by the number of directors that may be elected by preferred stock entitled to
elect directors as a class. Enron has the right to direct Atlantic Water Trust
to elect or replace the other half of Azurix's directors. As a result, following
the offering, Enron and Marlin Water Trust will continue to exert significant
influence over the policies, management and affairs of Azurix and the outcome of
most corporate actions requiring

stockholder approval, including the approval of transactions involving a change
in control of Azurix. See "Transactions with Enron, Atlantic Water Trust and
Marlin Water Trust," "Principal and Selling Stockholders" and "Shares Eligible
for Future Sale."
    
 
   
                            TRANSACTIONS WITH ENRON
    
 
   
     We have entered into agreements with Enron for purposes of governing
ongoing relationships following the offering, including a business opportunities
agreement, a services agreement and related sublease, a credit agreement and a
license agreement and related cost sharing agreement. The business opportunities
agreement limits the scope of our business to the businesses generally
identified in this prospectus and activities incidental to those businesses. The
agreement also provides that Enron and its affiliates may engage in
water-related businesses, even if those businesses have a competitive impact on
Azurix. Under the services agreement, Enron provides various corporate staff and
support services to us. We expect to incur costs for services used under the
services agreement of approximately $15 million annually. Under the credit
agreement, Enron provides funds to us for general, administrative and operating
expenditures. The credit agreement is a revolving facility which matures
December 15, 2001 or 90 days following the date that Enron or its affiliates do
not own or have the power to vote at least one-third of our capital stock
ordinarily entitled to vote for the election of directors and fewer than
one-third of our directors are officers, directors or employees of Enron or its
affiliates. The total commitment under the credit agreement is $180 million.
Advances under the credit agreement bear interest at the federal funds rate plus
1.50%. The license agreement permits Azurix to use the phrase "an Enron Company"
and the Enron logo in identifying Azurix as part of the Enron enterprise. The
cost sharing agreement provides for a sharing of Enron's trademark costs with
Azurix and Enron's other affiliates. See "Transactions with Enron, Atlantic
Water Trust and Marlin Water Trust" for a more detailed discussion of these
agreements.

                                                 estimated expenses. Azurix will not receive any

                                                 stockholder. We intend to use approximately $254.2

                                                 indebtedness. We intend to use the remaining proceeds,

     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 is derived from the unaudited condensed consolidated pro forma
financial data included elsewhere in this prospectus. The unaudited pro forma
income statement and other 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, the sale by Wessex of 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 and the offering, as though
each occurred on January 1, 1998. The unaudited pro forma balance sheet data
gives effect to the offering as though it occurred on March 31, 1999. The
unaudited pro forma income statement and other financial data presented below
are 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, the sale by Wessex of its interest in UK Waste and the
offering occurred on January 1, 1998, or indicative of our financial position
had the offering occurred on March 31, 1999, and should not be viewed as
indicative of operations or financial position 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 basic and diluted earnings per common share amounts for Wessex are not
    meaningful on a comparative basis to Azurix and, therefore, are not
    presented.
    
 
   
(2) 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
    accounting principles and should not be considered in isolation or as a
    substitute for operating profit, as an indicator of liquidity or as a
    substitute for net cash provided by operating activities. This method may
    not be comparable to the EBITDA calculations of other entities.
    
 
   
(3) The year ended March 31, 1998 includes a windfall tax of $162.3 million,
    which has been described by the U.K. Government as a one-time tax. Excluding
    the effect of this tax, for the year ended March 31, 1998, Wessex's net
    income would have been $179.0 million.
    
 
   
(4) As adjusted to reflect the application of the net proceeds to Azurix from
    the offering. Azurix has drawn $182.9 million under its senior credit
    facility as of May 21, 1999. Azurix intends to use $182.2 million of the net
    proceeds from the offering along with available cash to repay this
    indebtedness. Following the application of the net proceeds from the
    offering, $387.4 million of borrowing capacity under the senior credit
    facility will be available to fund future acquisitions. It is expected that
    $365.7 million of this facility, along with $72.9 million of proceeds from
    the offering, will be used to fund the $438.6 million acquisition of an
    interest in concessions in two regions of the Province of Buenos Aires,
    Argentina.

                                  RISK FACTORS
 
   
     Investing in our common stock will provide you with an equity ownership
interest in Azurix. As an Azurix stockholder, you will be subject to risks
inherent in our business. The performance of your shares will reflect the
performance of our business relative to, among other things, competition, market
conditions and general economic and industry conditions. The value of your
investment may increase or decline and could result in a loss. You should
carefully consider the following factors as well as other information contained
in this prospectus before deciding to invest in shares of the common stock.
    
 
   
BECAUSE WE HAVE A LIMITED OPERATING HISTORY, OUR FUTURE OPERATING RESULTS ARE
DIFFICULT TO FORECAST AND OUR FUTURE FINANCIAL OR OPERATING RESULTS MAY BE
MATERIALLY DIFFERENT FROM THE RESULTS IN THIS PROSPECTUS. THESE DIFFERENCES
COULD ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK.
    
 
   
     We are a new company with a limited operating history. Our limited
operating history and the unpredictable results of our acquisition strategy make
it difficult to forecast our future operating results. The financial data
presented in this prospectus may not be indicative of our future financial or
operating results. We expect to experience significant competition in bidding
and negotiating for water projects worldwide. As a new company, we will face
competition from companies that have a longer operating history and have more
experience in bidding for water and wastewater projects. Our limited operating
history may make it difficult for us to qualify for, or be successful in,
bidding. For example, we may be at a disadvantage in bidding for some projects
when we do not have a history of operating in a country or region, or when we do
not have a history of operating a water or wastewater system or individual
treatment plant of a size comparable to the system or facility being privatized
or built.
    
 
     We will derive our consolidated operating revenues almost exclusively from
the operations of Wessex until such time as our other investments begin to
generate revenue. Operating revenues from Wessex may not be available for
distribution to Azurix due to operating and financing requirements of Wessex,
financing requirements of intermediate companies, regulatory developments
affecting the rates Wessex may charge its customers and other regulatory or
other restrictions on its ability to pay dividends to its shareholders.
 
   
OUR PROFITABILITY AND PROSPECTS FOR GROWTH ARE HIGHLY DEPENDENT ON COMPLETING
ACQUISITIONS AND DEVELOPING PROJECTS, AND WE MAY NOT BE ABLE TO COMPLETE
ACQUISITIONS AND DEVELOP PROJECTS SUCCESSFULLY.
    
 
   
     There is a risk that we may not be able to complete acquisitions of water
and wastewater assets and develop projects successfully 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 we ultimately will acquire. Because part of our
business strategy is to grow through acquisitions and development projects, we
have recently put in place a business development effort with associated
general, administrative and operating expenses. To the extent we are not
successful in completing acquisitions and development projects, these expenses
will not be absorbed by revenues associated with those acquisitions and
development projects and will decrease our net income. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --

WATER AND WASTEWATER COMPANIES FACE PRICE AND OTHER REGULATION THAT COULD REDUCE
OUR OPERATING REVENUES.
    
 
   
     Governments generally regulate the prices that water and wastewater
companies may charge their customers and the competitive environment in which
they operate. Regulatory regimes vary from country to country and at times can
give great discretion to the regulatory authority. Moreover, the regulatory
authorities in countries where we currently operate, or may operate in the
future, could change without notice, as could the regulations they promulgate.
These changes could cause reductions in our operating revenues. For example, 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. In setting price limits, the Director must act in the
manner he considers best calculated to ensure that water companies are able to
finance the proper carrying out of their functions, in particular, by securing a
reasonable return on their capital.
    
 
   
     In October 1998, the Director proposed an initial price cut for Wessex in
excess of 17.5% from 1999-2000 to 2000-2001, with prices gradually increasing
thereafter but remaining below the 1999-2000 levels in 2004-2005. Following this
proposal, the U.K. Government announced its decision to require greater capital
expenditures for water and wastewater companies for environmental improvements.
Subsequently, in its April 1999 business plan filed with the Director, Wessex
proposed stable prices from 1999-2000 to 2000-2001, with prices gradually
increasing to 18% higher than current levels in 2005, primarily to fund capital
expenditures mandated by the new environmental standards. The Director will
consider the business plan in his review. The Director has stated that he will
publish draft price limits in July 1999 with the final determination being made
in November 1999. These price limits may differ materially from the Director's
original proposal. Although we are unable to predict the precise outcome of the
current U.K. periodic review, if Wessex were required to cut its prices as
originally proposed by the Director, Wessex's regulated operating revenues,
which represent approximately 90% of our total operating revenues, would be
reduced by approximately 17.5% and its earnings would be reduced materially.
    
 
FAILURE TO IDENTIFY AND ASSESS ACCURATELY THE RISKS RELATED TO AN ACQUISITION OR
PROJECT COULD REDUCE OUR OPERATING RESULTS, INCLUDING EARNINGS.
 
   
     In evaluating potential transactions, we make assumptions and projections
based on the potential for increased returns, future regulatory and rate case
changes and the engineering, operations, financing, economic structuring,
insurance, tax, environmental, legal and accounting risks relating to each
transaction. Forecasts, estimates and information provided by local governments
and other sources used to bid for public tenders can prove to be materially
inaccurate or incomplete, resulting in projections for capital expenditures to
improve or build water systems that are below what is ultimately required. If
the assumptions on which we base our decision to acquire assets or develop a
project prove to be incorrect in any material respect, either because of
inaccurate or incomplete information provided by the other party or parties to
the transaction or because of a failure by us to accurately identify or assess
the risks or capital requirements related to a proposed acquisition or project,
then our operating results, including earnings, could be materially adversely
affected. Although we attempt to identify all risks associated with any given
transaction, no assurance can be given that we will identify all risks related
to a transaction.
    
 
BECAUSE OUR BUSINESS REQUIRES SUBSTANTIAL CAPITAL EXPENDITURES, DIFFICULTY
FINANCING OUR OPERATIONS, ACQUISITIONS AND PROJECTS COULD LIMIT OUR GROWTH AND
REDUCE OUR EARNINGS.
 
   
     The water assets and projects in which we plan to invest may require
substantial capital expenditures, especially early in the life of our
investments. We intend to finance our investments and projects using various
techniques and instruments such as debt financing, project financing and equity
investments. We expect to engage in leveraged transactions, and we may pledge
all or substantially all of our assets. For example, the capital stock of Wessex
is pledged as security for the senior credit facility of Azurix Europe Ltd,
Wessex's holding company. In addition, there is a risk that financing may not be
readily available to acquire water and wastewater assets or develop projects.
Our ability to arrange financing will be affected
    
                                       10
<PAGE>   16
 
by general economic and capital market conditions, credit availability from
banks or other lenders and the risks inherent in particular concessions,
projects or countries. In particular projects, we may have a co-owner with
limited resources or that may default on its obligations to contribute capital
to the project. Enron is not obligated to provide additional financial support
to Azurix for any capital expenditures or investments.
 
IF WE DO NOT HAVE OPERATIONAL CONTROL IN A PROJECT, OUR OPERATING REVENUES AND
EARNINGS COULD BE REDUCED.
 
     We may invest in water and wastewater projects and assets in which we do
not own a majority of the project or assets. In addition, we may invest in or
own projects and assets with partners, co-venturers and other parties, including
governmental entities. Some jurisdictions require participation of employees or
other stakeholders in company management. In these cases, major decisions may
require the consent of other equity owners or stakeholders.
 
     We may also invest in projects and assets where we do not serve as
operator. For example, we do not have operational control in our Mendoza,
Argentina concession. In these cases, our ability to direct the outcome of
matters with respect to the operations of the project or assets could be
limited. A lack of operational control in a project could materially and
adversely affect our interest in the project and, as a result, our operating
revenues and earnings from the project.
 
   
IF WE ENCOUNTER PROBLEMS INTEGRATING ACQUISITIONS AND MANAGING OUR GROWTH, OUR
FINANCIAL RESULTS AND THE MARKET PRICE OF OUR COMMON STOCK COULD BE MATERIALLY
ADVERSELY AFFECTED.
    
 
     We intend to grow in part through acquisitions of water and wastewater
assets. Because we are pursuing acquisitions around the world and because we are
actively pursuing a number of opportunities simultaneously, we may encounter
unforeseen expenses, difficulties, complications and delays, including
difficulties in staffing and providing operational and management oversight. As
we expand our operations through acquisitions, we may encounter difficulties
integrating such acquisitions and successfully managing the growth of a
portfolio of water and wastewater assets that is diverse both with respect to
types of assets and their location. We cannot assure you that our current
management, personnel and other corporate infrastructure will be adequate to
manage our growth or that our systems, procedures and controls will be adequate
to support our expanding operations. To the extent we encounter problems in
integrating acquisitions and managing our growth, our financial results and the
market price of our common stock could be materially adversely affected.
 
ENVIRONMENTAL FACTORS AND CHANGES IN REGULATIONS COULD INCREASE OUR COSTS OR OUR
LIABILITIES.
 
     There is a risk that changes in regulations applying to the water supply or
wastewater treatment services industry or new, revised or inconsistent
interpretations of these regulations may adversely affect our financial
condition and results of operations. Water companies are subject to water
quality risks related to contamination of drinking water supplies or
environmental danger from effluent discharges. The occurrence of these or other
risks could have a material adverse effect on our financial position and results
of operations.
 
     In addition, many countries in which we plan to do business have recently
developed, or are in the process of developing, new regulatory and legal
structures that regulate the delivery of drinking water and wastewater services
and accommodate private and foreign-owned water businesses. In some instances,
these regulatory and legal structures and their interpretation and application
by administrative agencies are relatively new and incomplete. The interpretation
of existing rules can be expected to evolve over time and may have an
unpredictable impact on our business. We anticipate future changes in, or
decisions affecting, regulatory regimes that will serve to expand or tighten
regulatory controls. Some of these changes or decisions could have a material
adverse effect on our financial position and results of operations.
 
   
     In our industrial services business, we may handle hazardous substances 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
    
 
                                       11
<PAGE>   17
 
expenses related to the handling of hazardous substances. Although we maintain
insurance against many of these risks, we cannot be certain that insurance
proceeds received under our policies would adequately cover all liabilities we
might incur.
 
LIABILITY FOR WATER SUPPLY CONTAMINATION COULD RESULT IN MATERIAL LOSSES AND
COSTS.
 
   
     Where we supply water to end-users, our business is subject to risks of
contamination of the water supply, which could result in disease or even death
or otherwise endanger the public health. As a result of contamination, we could
be subject to civil, criminal or regulatory 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
remain at all times free of contaminants. Although we maintain insurance against
many of these risks, we cannot be certain that insurance proceeds received under
our policies would adequately cover all liabilities we might incur.
    
 
POLITICAL AND ECONOMIC CHANGES IN COUNTRIES IN WHICH WE OPERATE COULD ADVERSELY
AFFECT OUR OPERATING RESULTS.
 
     The success of our strategy in many countries will depend on a political
and economic environment that will accommodate foreign investment and project
development. Our operations will be subject to political and economic risks,
including risks of war, terrorism, expropriation, nationalization, renegotiation
or nullification of existing contracts, changes in rates and methods of taxation
and foreign exchange controls or governmental restrictions on the repatriation
of hard currency. You should be aware that we will operate in countries whose
economies differ in many respects from the economies of the United States,
Canada and most Western European countries, including their structure, levels of
capital reinvestment, growth rate, government involvement, resource allocation,
self-sufficiency, rate of inflation and balance of payments position. In many of
these countries, the government retains significant control over the economy.
Thus, there is a risk that future government actions, especially with respect to
nationally important facilities such as water systems, could have a material
adverse effect on our financial condition and results of operations.
 
WORK STOPPAGES AND OTHER LABOR RELATIONS MATTERS COULD ADVERSELY AFFECT OUR
OPERATING RESULTS.
 
   
     We are subject to a risk of work stoppages and other labor relations
matters because we have invested and will invest in the future in assets and
projects utilizing a workforce that in many cases will be unionized. For
example, all or a portion of the work forces at Wessex, Mendoza, Cancun and
Philip Utilities are represented by unions. Workers at the Hamilton-Wentworth
facility operated by Philip Utilities have been working under the terms of a
collective bargaining agreement that expired on March 31, 1999. Although
negotiations for a new contract are continuing, there can be no assurance that a
new agreement will be entered into or, if entered into, will be on favorable
terms. In addition, our ability to obtain an adequate return on an investment
will often depend on our success in optimizing the labor force through voluntary
and sometimes involuntary staff reductions. There is a risk that layoffs, where
implemented, could trigger community or union problems. We cannot assure you
that issues with our labor forces will be resolved favorably to us in the future
or that we will not experience work stoppages in future years.
    
 
CHANGES IN CURRENCY EXCHANGE RATES, LIMITATIONS ON SENDING FUNDS OUT OF A
FOREIGN COUNTRY AND FOREIGN CURRENCY RESTRICTIONS OR SHORTAGES COULD ADVERSELY
AFFECT OUR OPERATING RESULTS.
 
     Because we conduct operations outside the United States, limitations on the
right to convert currency or to take it out of a foreign country, changes in
exchange rates and the capacity of currency exchange markets may adversely
affect our ability to repatriate profits. As of December 31, 1998, 98.5% of our
total
                                       12
<PAGE>   18
 
   
liabilities were non-U.S. dollar denominated. For the year ended December 31,
1998, 100% of our operating revenues were non-U.S. dollar denominated but were
in the same currencies as our non-U.S. dollar denominated liabilities. Legal
restrictions or shortages in currencies in countries outside the United States
may prevent us from converting sufficient local currency to enable us to comply
with our currency payment obligations not denominated in local currency or to
meet our operating needs and debt service requirements.
    
 
OPERATING IN COUNTRIES WITHOUT ADEQUATE REVENUE COLLECTION SYSTEMS COULD REDUCE
OUR OPERATING REVENUES.
 
   
     There is a risk that we will operate in countries whose legal systems do
not have established or well-enforced collection mechanisms for 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 operating revenues from future U.S. operations do
not exceed the expenses we incur in the United States in supporting our
worldwide operations.
 
OPERATING IN COUNTRIES WITH UNDEVELOPED LEGAL SYSTEMS COULD ADVERSELY AFFECT OUR
BUSINESS BECAUSE WE MAY ENCOUNTER DIFFICULTIES ENFORCING OUR CONTRACTUAL RIGHTS.
 
   
     Developing countries in which we may pursue opportunities may not have well
established legal systems and lack a well-developed, consolidated body of laws
governing foreign investment enterprises. The uncertainty of the legal
environment in these countries could make it difficult for us to enforce our
rights, or those of our operating companies, under agreements relating to our
operations. In addition, the administration of laws and regulations by
government agencies in such countries may be subject to considerable discretion
or prejudice against foreigners or private investors. As these legal systems
develop, foreign investors may be adversely affected by new laws and changes to
existing laws. In addition, in countries where adequate laws and well-developed
legal systems do exist, it may not be possible to obtain swift and equitable
enforcement of such laws.
    
 
RESTRICTIONS IN DEBT AGREEMENTS COULD LIMIT OUR GROWTH AND OUR ABILITY TO
RESPOND TO CHANGING CONDITIONS.
 
   
     We conduct substantially all of our operations through subsidiaries, and
substantially all of our assets consist of equity in our subsidiaries. Some of
the debt financing arrangements to which our subsidiaries are a party impose
restrictions on their business operations, which may affect our business
operations. The covenants contained in the credit agreements to which Azurix
Europe and Wessex are parties will have several restrictive effects on our
future operations. For example, the covenants contained in the senior credit
facility for Azurix Europe require Wessex to meet financial tests and limit
Wessex's ability to borrow additional funds or dispose of assets. These
covenants could hinder our flexibility in planning for, and reacting to, changes
in our business. In addition, our ability to obtain additional financing for
working capital, capital expenditures, acquisitions, general corporate and other
purposes at the Azurix level may be limited by the fact that the capital stock
of Wessex is pledged as security for Azurix Europe's senior credit
    
 
                                       13
<PAGE>   19
 
   
facility. Additionally, covenants contained in the senior credit facility
restrict Azurix Europe from paying dividends to Azurix. This could limit our
ability to pay dividends on our common stock. See "Description of Indebtedness."
    
 
FAILURE OF COMPUTER SYSTEMS TO RECOGNIZE YEAR 2000 COULD HAVE AN ADVERSE EFFECT
ON OUR BUSINESS.
 
     Year 2000 problems could result from computer hardware and software using
two digits rather than four digits to define the applicable year. These problems
include operational inefficiencies, systems failures, business disruptions and
lost revenues attributable to the inability of these two digit systems to
recognize the Year 2000. We intend to implement Enron's Year 2000 plan to
identify and remediate our Year 2000 problems. However, because we have not
completed our analysis of our Year 2000 readiness or the Year 2000 readiness of
parties on whom we rely, we cannot ensure that the identification and
remediation of our Year 2000 problems will be successful.
 
     If our mission-critical information systems fail or if suppliers on which
we depend for essential goods and services experience mission-critical
information system failures, our business could be materially adversely
affected. We could face substantial claims by governments, governmental
authorities or customers, as well as loss of operating revenues, due to service
interruptions, violations of environmental regulations, inability to fulfill
contractual obligations, inability to account for obligations and increased
expenses associated with litigation, harm to persons or to property,
stabilization of operations following system failures and the execution of
contingency plans. In addition, we could face claims of damage to persons or
property as the result of improperly treated water or wastewater.
 
     Our preliminary assessment of our Year 2000 issues has not demonstrated a
need to incur material Year 2000 costs. However, the following factors could
result in actual Year 2000 costs being higher than anticipated:
 
     - We intend to engage in future acquisitions and could acquire a business
       with significant Year 2000 problems.
 
     - We depend on third parties, including customers, suppliers and service
       providers, who may fail to address adequately their Year 2000 problems.
 
     - We rely on automated plant systems, computerized billing procedures and
       other embedded chip technologies that could necessitate expensive
       corrective actions.
 
     For a more detailed discussion of the state of our Year 2000 readiness, the
costs we anticipate incurring to become Year 2000 ready and our Year 2000
contingency plans, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Year 2000."
 
OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT, THE LOSS OF WHOM COULD
DISRUPT OUR BUSINESS OPERATIONS.
 
     We depend on the continued employment of key management personnel we have
brought in from Enron, Wessex and other multinational companies. We have entered
into employment agreements with these executives. If these officers resign or
become unable to continue in their present role and if they are not adequately
replaced, our business operations could be materially adversely affected. See
"Management."
 
   
CHANGES IN OUR RELATIONSHIP WITH ENRON COULD INCREASE OUR COSTS BECAUSE WE RELY
ON ENRON FOR CORPORATE STAFF AND SUPPORT SERVICES.
    
 
   
     We have entered into an agreement with Enron pursuant to which Enron
provides various corporate staff and support services to us. These services
include information technology, office space, building maintenance, security and
other office services as well as employee development, training and maintenance
of compensation and other benefits programs. We also may utilize Enron's
regulatory affairs, marketing affairs, treasury and risk assessment and control
departments. In addition, Azurix may continue to
    
 
                                       14
<PAGE>   20
 
   
participate in Enron's corporate insurance program. The agreement provides that
we may use the international offices of Enron and its affiliates for projects,
subject to our mutual agreement with Enron or its affiliates on a
project-by-project basis. Due to prior commitments that Enron or its affiliates
may have in a particular office or due to other reasons, there is a risk that
Enron or its affiliates may not permit Azurix to use a particular international
office for a particular project.
    
 
   
     Our agreement with Enron is for an indefinite term, but may be terminated
on 180 days' notice. If the agreement is terminated, we expect that we would be
able to arrange alternate suppliers for all the services important to our
business. We expect that these services would be available from third parties at
costs similar to those we pay Enron. However, if we have to replicate
facilities, services or employees that we are not using full time, our costs
would increase. It is not possible to predict the specific areas where our costs
would increase, as that depends on the growth and needs of our business at the
time of any such termination.
    
 
   
OUR BUSINESS OPPORTUNITIES COULD BE LIMITED BECAUSE ENRON AND ITS AFFILIATES MAY
COMPETE WITH AZURIX IN WATER-RELATED ACTIVITIES AND BECAUSE AZURIX MAY ONLY
ENGAGE IN ACTIVITIES GENERALLY IDENTIFIED IN THIS PROSPECTUS, INCIDENTAL
ACTIVITIES AND OTHER ACTIVITIES AS ATLANTIC WATER TRUST OR ENRON MAY APPROVE.
    
 
   
     Enron and Azurix have entered into an agreement that limits the scope of
Azurix's business and provides that Enron and its affiliates may engage in
water-related businesses, even if those businesses have a competitive impact on
Azurix. In general, Enron is 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 has agreed to
indemnify Enron and its officers, directors and employees against any claim that
Enron's pursuit of any water business was a breach of any duty owed by Enron to
Azurix, provided Enron has followed the rules described above. Were Enron to
decide to pursue activities in the water or wastewater industry, its size,
access to capital and experience in developing products and markets could make
it a strong competitor.
    
 
   
     The agreement requires 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. Azurix has agreed not to amend its
certificate of incorporation to expand its purpose clause without Enron's prior
written consent. The agreement thus limits our ability to pursue potentially
profitable activities that are not primarily in the water and wastewater sector,
even though those opportunities come to our attention on account of our
activities in water and wastewater. For example, some jurisdictions may choose
to privatize their water and other utility assets together. As a result of this
agreement, we would need Enron's consent to pursue the privatization if the
water and wastewater aspects were not expected to represent a majority of the
value.
    
 
   
     The agreement restricts Enron and Azurix from taking action to restrict
each others' businesses, to cause either of them to violate any law or to
subject them to regulation under the U.S. Public Utility Holding Company Act of
1935. The agreement expires the first date on which Enron and its affiliates do
not individually or collectively, directly or indirectly, own or have the power
to vote at least one-third of the shares of Azurix ordinarily entitled to vote
for the election of directors, and fewer than one-third of the directors of
Azurix are persons who are employees, officers or directors of Enron or any
affiliate of Enron. See "Transactions with Enron, Atlantic Water Trust and
Marlin Water Trust -- Agreement Regarding Business Opportunities and Related
Matters."

THROUGH ATLANTIC WATER TRUST, ENRON AND MARLIN WATER TRUST WILL CONTROL THE
OUTCOME OF STOCKHOLDER VOTING AND MAY EXERCISE THIS VOTING POWER IN A MANNER
ADVERSE TO THE INTERESTS OF OTHER STOCKHOLDERS.
    
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately 68.7% of our outstanding common stock, 64.1% if the underwriters'
over-allotment option is exercised in full. Each of Enron and Marlin Water Trust
owns a 50% voting interest in Atlantic Water Trust. To date, Enron has appointed
all of the directors of Atlantic Water Trust and Azurix, although Marlin Water
Trust at any time has the right to elect or replace half of the directors of
Atlantic Water Trust and currently up to half of the Azurix directors. Following
the offering, as long as Atlantic Water Trust owns a majority of our outstanding
voting 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 voting stock held by persons other than Atlantic Water
Trust, Enron and its affiliates. Furthermore, Marlin Water Trust, with the
consent of the holders of a majority of our outstanding voting 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.
In each case, Marlin Water Trust's right to designate directors shall be reduced
by the number of directors that may be elected by preferred stock entitled to
elect directors as a class. 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. 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 will control
the outcome of corporate actions requiring stockholder approval, including the
approval of transactions involving a change in control of Azurix. Enron and
Marlin Water Trust's interests may differ from those of Azurix's other
stockholders. As a result, Enron and Marlin Water Trust may vote Azurix stock in
a manner adverse to other stockholders. See "Transactions with Enron, Atlantic
Water Trust and Marlin Water Trust" and "Principal and Selling Stockholders."
    
 
A MAJORITY OF OUR DIRECTORS MAY HAVE CONFLICTS OF INTEREST BECAUSE THEY ARE ALSO
ENRON DIRECTORS OR OFFICERS.
 
   
     Currently, a majority of our directors are also directors or officers of
Enron, a situation that may create conflicts of interest. The directors and
officers of Enron have fiduciary duties to manage Enron, including its
investments in subsidiaries and affiliates such as Azurix, in a manner
beneficial to Enron and its stockholders. Similarly, the directors and officers
of Azurix have fiduciary duties to manage Azurix in a manner beneficial to
Azurix and its stockholders. In some circumstances, the duties of these
directors and officers of Enron may conflict with their duties as directors of
Azurix. In addition, other conflicts of interest exist and may arise in the
future as a result of the extensive relationships between Enron and Azurix.
Enron and Azurix have agreed that conflicts of interest between Enron and Azurix
may be resolved through approval by a majority of the directors of Azurix not
associated with Enron. See "Transactions with Enron, Atlantic Water Trust and
Marlin Water Trust" 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, 117,100,000 shares of our common stock will be
outstanding. Of these shares, the 36,600,000 shares to be sold in the offering
will be freely transferable and may be sold without restriction or further
registration under the Securities Act, except for any shares acquired by an
"affiliate" of Azurix as defined in Rule 144 under the Securities Act. In
connection with the offering, Azurix, Enron and the selling stockholder, holding
80,500,000 shares of common stock post-offering, have agreed, with exceptions
specified in the lock-up agreements, not to sell any shares of common stock for
a period of 180 days after
    
                                       16
<PAGE>   22
 
   
the date of this prospectus without the prior written consent of Merrill Lynch,
Pierce, Fenner & Smith Incorporated. Upon expiration of the lock-up period, the
shares outstanding and owned by the selling stockholder 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 addition, the
selling stockholder has registration rights for all of its shares of our common
stock. See "Transactions with Enron, Atlantic Water Trust and Marlin Water
Trust" and "Shares Eligible for Future Sale."
    
 
   
     Options to purchase approximately 8.5 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. After the offering, we intend to file a registration
statement covering the sale of approximately 8.5 million shares of common stock
reserved for issuance under our stock plan. See "Management -- Stock Plan."
    
 
   
     Marlin Water Trust, or the trustee under its senior notes indenture, may be
required to cause Atlantic Water Trust to sell shares of our common stock owned
by Atlantic Water Trust if the senior notes of Marlin Water Trust have not been
repaid on or before December 15, 2001 or earlier if specified events occur.
These events include defaults under specified debt obligations of Azurix, Enron
or Marlin Water Trust or a downgrading of Enron senior debt to below "Baa3" by
Moody's Investors Service, Inc., "BBB-" by Standard & Poor's Ratings Services or
"BBB-" by Duff & Phelps Credit Rating Co. and a decline in Enron's common stock
price below $37.84. The last sale price of Enron common stock, as reported by
the New York Stock Exchange, on May 20, 1999 was $74.0625. Atlantic Water Trust
may also elect to sell shares of our common stock in advance of the December 15,
2001 maturity of the senior notes of Marlin Water Trust in order to fund the
prepayment of such debt. See "Principal and Selling Stockholders -- Atlantic
Water Trust."
    
 
OUR CERTIFICATE OF INCORPORATION CONTAINS PROVISIONS THAT COULD DISCOURAGE A
TAKEOVER.
 
     Our certificate of incorporation authorizes our Board of Directors to issue
preferred stock without stockholder approval. If our Board of Directors elects
to issue preferred stock, it could be more difficult for a third party to
acquire us. In addition, provisions of the certificate of incorporation, such as
a staggered board of directors and limitations on the removal of directors, no
stockholder action by written consent and limitations on stockholder proposals
at meetings of stockholders, could make it more difficult for a third party to
acquire control of us, even if such change of control would be beneficial to
stockholders. See "Description of Capital Stock."
 
THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK AND OUR STOCK PRICE
MAY FLUCTUATE.
 
     There has not been a public market for our common stock. We will list the
common stock for trading on the New York Stock Exchange. We do not know the
extent to which investor interest in Azurix will lead to the development of a
trading market for the common stock or how the common stock will trade in the
future. The initial public offering price will be determined by negotiations
among us, Atlantic Water Trust, Enron and the underwriters. Investors may not be
able to resell their shares at or above the initial public offering price. See
"Underwriting."
 
   
     The price at which the common stock will trade depends upon a number of
factors, including our historical and anticipated operating results and general
market and economic conditions, some of which are beyond our ability to control.
Factors such as quarterly fluctuations in our financial and operating results,
developments affecting us, our customers, the water markets in which we compete
or the water industry, including the factors listed under "Forward-Looking
Statements," also could cause the market price of the common stock to fluctuate
substantially. In addition, the stock market has from time to time experienced
extreme price and volume fluctuations. These broad market fluctuations may
adversely affect the market price of the common stock.

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

                                USE OF PROCEEDS
 
   
     We expect the proceeds to Azurix from this sale of common stock to be
approximately $327.1 million, after deducting underwriting discounts and
commissions and estimated expenses. Azurix will not receive any proceeds from
the sale of common stock by the selling stockholder.
    
 
   
     We intend to use the net proceeds that we receive to repay approximately
$72 million that Enron advanced to us to fund our general, administrative and
operating expenses, from our inception through May 21, 1999, in addition to
capital expenditures. This includes $28.5 million advanced to us by Enron to
fund our acquisition of, and loan to, our investment in Cancun. The amount due
to Enron is non-interest bearing and has no maturity date.
    
 
   
     We intend to use $182.2 million of the net proceeds to repay indebtedness
under the senior credit facility entered into on May 10, 1999 by Azurix Europe
Ltd, an indirect, wholly owned subsidiary of Azurix and the holding company for
Wessex. The amounts drawn under the senior credit facility bear interest at a
floating London interbank offered rate, plus a margin. If loans outstanding at
the time of a new loan are less than 50% of the total commitment of the
facility, then the margin applied to the new loan will equal 0.75% per annum. If
loans outstanding at the time of a new loan are greater than or equal to 50% of
the total commitment of the facility, then the margin applied to the new loan
will equal 1.00% per annum. Azurix Europe will pay a commitment fee on the
undrawn, uncancelled amount of the facility at the rate of 0.375% per annum. The
senior credit facility is for a period of three years. The indebtedness
outstanding under the senior credit facility has been incurred for the following
purposes:
    
 
   
     - To repay $67.8 million under Azurix Europe's former senior credit
       facility, which was entered into to finance the acquisition of Wessex
    
 
   
     - To repay $8.1 million under the senior credit facility, which was used to
       pay fees and expenses related to this facility
    
 
   
     - To finance $106.3 million in connection with the acquisition of Philip
       Utilities
    
 
   
     We intend to use the remaining proceeds of $72.9 million, along with funds
to be drawn under the senior credit facility, to fund the acquisition of an
interest in concessions in two regions of the Province of Buenos Aires,
Argentina. See "Business -- Pending Acquisition." Pending such acquisition, we
intend to invest the remaining proceeds of the offering in short-term,
investment-grade, interest-bearing securities.
    
 
   
     See "Description of Indebtedness -- Indebtedness of Azurix Europe" for a
description of the terms of the senior credit facility.
    
 
                                DIVIDEND POLICY
 
     We have not paid any dividends on our common stock and we do not currently
anticipate paying any dividends on our common stock. We currently intend to
retain all future earnings to fund the development and growth of our business.
The payment of any future dividends will be at the discretion of our Board of
Directors and will depend on our results of operations, financial condition,
capital requirements and other factors deemed relevant by our Board of
Directors.

                                    DILUTION
 
     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the net tangible book value per share of our common stock after
the offering. We calculate net book value per share by dividing the net assets
(total assets less liabilities) by the number of shares outstanding before the
offering. We calculate net tangible book value per share by dividing the net
tangible assets (total assets less liabilities and net intangible assets) by the
number of shares of common stock outstanding before the offering.
 
   
     The net book value and net tangible book value of Azurix as of March 31,
1999 were approximately $16.15 and $7.58 per share, respectively. Without taking
into account any changes in net book value or net tangible book value after
March 31, 1999, 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 March 31, 1999 would have been approximately $1,941.8
million, or $16.58 per share, and the pro forma net tangible book value of the
common stock as of such date would have been approximately $1,085.0 million, or
$9.27 per share. Assuming the offering had occurred at March 31, 1999, an
immediate increase in net book value of $0.43 per share to the existing
stockholder and an immediate dilution of $3.92 per share to new investors would
have occurred. The following table shows the effect of the offering as if the
offering had occurred at March 31, 1999 and illustrates the immediate increase
in net tangible book value of $1.69 per share to the existing stockholder and an
immediate dilution of $11.23 per share to new investors:

     The foregoing table excludes outstanding employee stock options of Azurix
to purchase approximately 8.5 million shares of common stock. The terms of the
options provide for vesting over a period of time, generally three to five
years. Assuming all options are exercised, pro forma net tangible book value per
share would increase $0.52 per share to $9.79 per share.
    
 
   
     The following table shows on a pro forma as adjusted basis at March 31,
1999, the number of shares of common stock purchased from us, the total

     Sales by the existing stockholder in this offering will reduce the number

total number of shares outstanding after the offering, and will increase the
number of shares held by new investors to 36,600,000 shares, or 31.3% of the
total number of shares outstanding after the offering. If the underwriters'
over-allotment option is exercised in full, the number of shares of common stock
held by the existing stockholder will be reduced to 75,010,000 shares, or 64.1%

    application of the net proceeds from the offering, $387.4 million of
    borrowing capacity under the senior credit facility will be available to
    fund future acquisitions. It is expected that $365.7 million of this

                  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 periods and dates indicated.
    
 
   
     The historical financial data for Azurix is derived from Azurix's audited
consolidated financial statements and unaudited interim financial statements
included elsewhere in this prospectus and includes the impact of the Wessex
acquisition from the date of acquisition. The historical financial data for the
three months ended March 31, 1999 is derived from financial statements that are
unaudited but include all adjustments, consisting of normal recurring
adjustments, that Azurix considers necessary for a fair presentation of its
financial position and results of operations for the period. The results for the
three months ended March 31, 1999 are not necessarily indicative of the results
for the full year. All of Azurix's 1998 results of operations occurred in the
fourth quarter of 1998, subsequent to the acquisition of Wessex. The historical
balance sheet data for Wessex as of March 31, 1998 and historical income
statement and other financial data 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 income statement and other financial data for the years ended March
31, 1995 and 1996 and the historical balance sheet data for Wessex as of March
31, 1995, 1996 and 1997 are derived from unaudited financial statements prepared
in accordance with U.S. generally accepted accounting principles that were
derived from Wessex's audited financial statements prepared in accordance with
U.K. generally accepted accounting principles.
    
 
   
     The unaudited pro forma financial data for Azurix is derived from the
unaudited condensed consolidated pro forma financial information included
elsewhere in this prospectus. The unaudited pro forma income statement and other
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, the sale by Wessex of its interest in UK Waste for $337.9 million and
the offering, as though each occurred on January 1, 1998. The unaudited pro
forma balance sheet data gives effect to the offering as though it occurred on
March 31, 1999. The unaudited pro forma income statement and other financial
data presented below are 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, the sale by Wessex of its interest in
UK Waste and the offering occurred on January 1, 1998, or indicative of our
financial position had the offering occurred on March 31, 1999 and should not be
viewed as indicative of operations or financial position in future periods.
    
 
   
     This information should be read in conjunction with "Capitalization,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," the Unaudited Condensed Consolidated Pro Forma Financial
Information and related notes thereto and the Consolidated Financial Statements
of Azurix and Wessex and related notes thereto included elsewhere in this
prospectus.

    related primarily to Wessex's interest in UK Waste.
 
   
(2) The year ended March 31, 1998 includes a windfall tax of $162.3 million,
    which has been described by the U.K. Government as a one-time tax. Excluding
    the effect of this tax, for the year ended March 31, 1998, Wessex's net
    income, 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 common 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.

    facility as of May 21, 1999. Azurix intends to use $182.2 million of the net
    proceeds from the offering along with available cash to repay this
    indebtedness. Following the application of the net proceeds from the
    offering, $387.4 million of borrowing capacity under the senior credit
    facility will be available to fund future acquisitions. It is expected that
    $365.7 million of this facility, along with $72.9 million of proceeds from
    the offering, will be used to fund the $438.6 million acquisition of an
    interest in concessions in two regions of the Province of Buenos Aires,
    Argentina.

OVERVIEW
 
     Azurix was incorporated on January 29, 1998. All of its operating results
and cash flows occurred during the fourth quarter of 1998 following the Wessex
acquisition. During 1998, Azurix indirectly acquired all of the outstanding
ordinary share capital of Wessex, and Enron contributed to Azurix the
outstanding common stock of a subsidiary that in June 1998 acquired an indirect
32.1% ownership interest in Obras Sanitarias Mendoza S.A. Wessex and Obras
Sanitarias Mendoza provide water and wastewater treatment services in
southwestern England and the Province of Mendoza, Argentina, respectively. In
December 1998, Enron contributed Azurix to Atlantic Water Trust and Marlin Water
Trust acquired a 50% voting interest in Atlantic Water Trust. Enron retained a
50% voting interest in Atlantic Water Trust.
 
BUSINESS ACQUISITION
 
   
     On October 2, 1998, Azurix, through its indirect wholly owned subsidiary
Azurix Europe, acquired over 90% of the outstanding ordinary share capital of
Wessex. On that same date, Azurix Europe issued notices to the remaining Wessex
ordinary shareholders, informing them that it intended to exercise its rights
under the English Companies Act to acquire compulsorily all of the outstanding
ordinary shares not held by Azurix Europe. The compulsory share acquisition was
completed in November 1998. The per share price paid to Wessex shareholders was
L6.30. The total cost of the Wessex acquisition, including transaction costs,
was $2.4 billion, plus the assumption of $481.5 million of existing Wessex debt.
The cost included cash consideration paid to Wessex shareholders, net of $1.7
million cash acquired, and the issuance of loan notes to Wessex shareholders in
the face amount of $119.8 million. The acquisition was financed through capital
contributions from Azurix's parent company totaling $1.6 billion and the
issuance of $0.8 billion in debt by Azurix Europe. Wessex had cumulative
mandatorily redeemable preference shares outstanding when it was acquired.
Wessex redeemed these shares in December 1998 for a cash payment of $106.4
million.
    
 
SALE OF INVESTMENT IN UNCONSOLIDATED AFFILIATE
 
     On November 30, 1998, Wessex sold its 50% interest in Wessex Waste
Management Ltd, a joint venture with Waste Management International Plc that
does business as UK Waste, for $337.9 million in cash. Azurix recorded no gain
or loss from the sale.
 
RECENT DEVELOPMENTS
 
   
     Azurix entered into an agreement on December 19, 1998 to purchase 49.9% of
an entity whose principal asset is the water concession for the city of Cancun,
Mexico. This agreement was not binding until material conditions were met, which
included modification of the concession agreement by the local water and
wastewater regulatory agency, approvals from the local antitrust and foreign
investment agencies, as well as agreement on the terms of the credit agreement,
security arrangements and other associated documents. These conditions were
satisfied subsequent to December 31, 1998. The purchase price was $13.5 million
and the acquisition closed on March 24, 1999. In addition, Azurix has agreed to
provide up to $25.0 million in debt financing, $15.0 million of which was funded
on February 25, 1999.
    
 
   
     On March 30, 1999, Azurix, through subsidiaries of Wessex, completed a U.K.
pounds sterling denominated bond offering in the amount of $484.2 million.
Wessex used $448.4 million of the proceeds from the sale of the 10-year bonds to
repay all outstanding amounts under its former bank credit facilities as well as
all outstanding amounts under uncommitted credit facilities. Any remaining
proceeds were
    
                                       25

available for general corporate purposes. The bonds mature March 30, 2009 and
bear interest of 5.875% payable annually. See "Description of
Indebtedness -- Indebtedness of Wessex."
    
 
   
     Effective May 1, 1999, Azurix signed an agreement with Enron pursuant to
which Enron provides various corporate staff and support services to Azurix.
These services include information technology, office space, building
maintenance, security and other office services as well as employee development,
training and maintenance of compensation and other benefits programs. Azurix may
utilize Enron's regulatory affairs, marketing affairs, treasury and risk
assessment and control departments. In addition, Azurix may continue to
participate in Enron's corporate insurance program. The agreement provides that
Azurix may use the international offices of Enron and its affiliates for
projects, subject to mutual agreement with Enron or its affiliates on a
project-by-project basis. The agreement provides that Azurix will reimburse
Enron for direct charges related to the Enron services and facilities that it
utilizes. Azurix will also be allocated an amount for overhead charges related
to Enron corporate staff and support services which it utilizes. This overhead
charge will be allocated based upon factors such as employee headcount, payroll
and square footage. Azurix management believes the allocation methods and costs
are reasonable. Costs for services used under the agreement are expected to be
approximately $15 million annually. The agreement is for an indefinite term, but
either party may terminate the agreement on 180 days' notice. Azurix intends to
enter into a related sublease with Enron providing for the use of office space
in Houston, Texas.
    
 
   
     Effective May 1, 1999, Azurix entered into a credit agreement with Enron,
whereby Enron will provide funds to Azurix for general, administrative and
operating expenses. The total commitment under the credit agreement will be $180
million. Advances under the credit agreement will bear interest at the federal
funds rate plus 1.50%. Amounts borrowed under the credit agreement may be
prepaid, in full or in part, at any time during the term of the credit
agreement. The credit agreement matures December 15, 2001 or 90 days following
the date that Enron or its affiliates do not own or have the power to vote at
least one-third of our capital stock ordinarily entitled to vote for the
election of directors and fewer than one-third of our directors are officers,
directors or employees of Enron or its affiliates.
    
 
   
     On May 10, 1999, Azurix Europe entered into a L425 ($686.0) million
revolving credit facility. On May 13, 1999, Azurix Europe borrowed approximately
$75.9 million, of which approximately $67.8 million was used to repay all of the
remaining indebtedness outstanding on its former senior credit facility and
approximately $8.1 million was primarily used to pay fees and expenses related
to this facility. On May 14, 1999, Azurix borrowed $107.0 million under this
revolving credit facility, primarily to fund the purchase of Philip Utilities. A
portion of the unused borrowing capacity under this facility secures outstanding
loan notes of $113.8 million. The facility bears interest at the London
interbank offered rate plus 0.75% to 1.0%, depending on the level of utilization
of the borrowing capacity. The facility terminates on May 10, 2002. See
"Description of Indebtedness -- Indebtedness of Azurix Europe."
    
 
   
     On May 18, 1999, Azurix acquired 100% of the stock of Canadian-based Philip
Utilities Management Corporation for $106.3 million. Philip Utilities is a water
and wastewater services company in the United States and Canada that provides
operations and management, engineering, residuals management and underground
infrastructure development services for municipal water and wastewater
facilities.
    
 
   
     On May 18, 1999, authorities in the Province of Buenos Aires, Argentina,
notified Azurix that, subject to final confirmation, Azurix will be awarded an
interest in 30-year water and wastewater concessions in two regions of the
province, at an aggregate price of $438.6 million. Assuming this award is
formally confirmed, Azurix will acquire a 90% interest in the concession
companies and take control of the systems on June 18, 1999.

     Approximately 90% of operating revenues is derived from water supplied and
wastewater treated for residential, commercial and industrial customers. The
supply of water is either metered, known as measured, or unmeasured. The charge
for wastewater treated is based upon a percentage of the water supplied and
charged to that customer.
    
 
   
     Wessex's subsidiary, SC Technology, sells and operates plants for drying
biosolids, the solid waste remaining after wastewater is treated. The majority
of SC Technology's operating revenues is derived from projects related to
selling and managing the construction of plants, and therefore each period's
operating revenues fluctuate according to the number of projects in progress.
Other unregulated activities include the sale of electricity and treatment of
organic waste.
    
 
   
     Operations and maintenance expense consists of the costs of supplying water
and treating wastewater, including the costs of maintaining and operating the
plant and equipment used in these processes. The main categories of cost include
labor, power, rent, real estate taxes, chemicals, transport, equipment, grounds
maintenance, and tankering. SC Technology's costs relate to the construction and
delivery of the plant being installed, including the cost of equipment, civil
engineering, building and labor.
    
 
     General and administrative expense includes personnel costs, transaction
expenses related to due diligence and overhead associated with Azurix's pursuit
of acquisitions and development projects, in addition to support functions such
as billing and customer services, quality and scientific services, regulation,
finance, human resources and public relations.
 
   
     The functional currency of Wessex is U.K. pounds sterling. Accordingly, its
results of operations, translated into U.S. dollars, are affected by the change
in currency exchange rates when comparing periods. The actual average exchange
rate for each applicable period used in translating the U.K. pounds sterling
functional results to U.S. dollars, in accordance with U.S. GAAP, is $1.63 per
L1.00 for the three

months ended March 31, 1999, $1.66 per L1.00 for the year ended December 31,
1998, $1.65 per L1.00 for the six months ended October 2, 1998, $1.64 per L1.00
for the year ended March 31, 1998 and $1.59 per L1.00 for the year ended March
31, 1997.
    
 
   
 AZURIX -- UNAUDITED PRO FORMA FOR THE YEAR ENDED DECEMBER 31, 1998
    
 
   
     The following discussion is derived from the Unaudited Condensed
Consolidated Pro Forma Financial Information included elsewhere in this
prospectus. The pro forma results discussed below include the 1998 results of
Wessex prior to its acquisition by Azurix.
    
 
   
     Operating revenues of $464.2 million were all derived from Wessex.
Approximately 91% of these revenues were derived from the sale of measured and
unmeasured water and wastewater services. Operating revenues from SC Technology
and other unregulated activities, accounted for 5% and 4% of total operating
revenues, respectively.
    
 
   
     Operations and maintenance expense was $120.9 million, of which 98% was
incurred by Wessex. Of this amount, $89.3 million relates to the costs of
supplying water and treating wastewater, including the costs of maintaining and
operating plant and equipment used in these processes, and $23.9 million relates
to the costs of the plants being installed by SC Technology.
    
 
   
  AZURIX -- THREE MONTHS ENDED MARCH 31, 1999
    
 
   
     Azurix had no operations as of March 31, 1998 and as a result, the
following discussion is limited to results of operations for the three months
ended March 31, 1999. All of its operating income occurred during the fourth
quarter of 1998 following the Wessex acquisition.
    
 
   
     Operating revenues of $116.9 million for the three months ended March 31,
1999 were derived from Wessex. Approximately 90% of these revenues relate to the
sale of measured and unmeasured water and wastewater services. Operating
revenues from SC Technology and other unregulated activities each accounted for
5% of total operating revenues.
    
 
   
     Operations and maintenance expense for the three months ended March 31,
1999, of which 98% was incurred by Wessex, was $31.8 million. Of this amount,
$22.1 million relates to the cost of supplying water and treating wastewater,
including the costs of maintaining and operating plant and equipment used in
these processes. In addition, $6.2 million relates to the cost of the plants
being installed by SC Technology.
    
 
   
     General and administrative expenses of $22.6 million for the three months
ended March 31, 1999 include $9.5 million related to Wessex's operations and
$12.8 million related to the pursuit of acquisitions and development projects.
The expenses related to acquisitions and development projects resulted from a
business strategy initiated in the fourth quarter of 1998. See "-- Outlook."
    
 
   
     Depreciation and amortization of $23.3 million for the three months ended
March 31, 1999 includes $5.4 million relating to amortization of goodwill
incurred by Azurix in its acquisition of Wessex. All of the depreciation expense
is derived from depreciation on the property, plant and equipment of Wessex. The
goodwill amortization and depreciation expense related to Wessex is based on a
preliminary purchase price allocation of Wessex.
    
 
   
     Net interest expense of $14.9 million for the three months ended March 31,
1999 is related to the Wessex acquisition financing, existing Wessex debt and
funds borrowed in the fourth quarter of 1998 to redeem outstanding preference
shares.
    
 
   
     Income tax expense of $8.4 million was incurred during the three months
ended March 31, 1999. The majority of Azurix's pre-tax operating income is
derived in the United Kingdom where the effective 1999 statutory tax rate is
30.25%. The primary reason for the difference between effective book tax rate of
34.3% and the effective statutory tax rate is the non-deductible amortization of
goodwill resulting from the acquisition of Wessex.
    
 
                                       28
<PAGE>   34
 
   
     Income tax expense is net of a tax benefit of $4.8 million related to
losses generated in the United States. A valuation allowance is not necessary
for this tax benefit due to expected future income resulting from finalizing
U.S. water projects and available tax planning strategies.
    
 
  AZURIX -- DATE OF INCEPTION TO DECEMBER 31, 1998
 
   
     Operating revenues of $119.7 million were derived from Wessex.
Approximately 90% of these revenues relate to the sale of measured and
unmeasured water and wastewater services. Operating revenues from SC Technology
and other unregulated activities accounted for 6% and 4% of total operating
revenues, respectively.
    
 
   
     Operations and maintenance expense totalled $31.6 million. Of this amount,
$21.8 million relates to the cost of supplying water and treating wastewater,
including the costs of maintaining and operating plant and equipment used in
these processes, and $7.1 million relates to the costs of the plants being
installed by SC Technology.
    
 
   
     General and administrative expenses of $20.3 million include $7.7 million
related to Wessex's operations and $12.3 million related to the pursuit of
acquisitions and development projects. The expenses related to acquisitions and
development projects result from a business strategy initiated in the fourth
quarter of 1998. See "-- Outlook."
    
 
     Depreciation and amortization of $22.2 million includes $5.5 million for
the amortization of goodwill incurred by Azurix in the acquisition of Wessex.
All of the depreciation expense is derived from depreciation on the property,
plant and equipment of Wessex. The goodwill amortization and depreciation
expense related to Wessex is based on a preliminary purchase price allocation of
Wessex.
 
     Interest expense is related to the Wessex acquisition financing, existing
Wessex debt and funds borrowed in the fourth quarter to redeem the outstanding
preference shares.
 
     The effective tax rate for the period was 64.2%. The difference between the
effective tax rate and the U.S. statutory rate of 35% (U.K. statutory rate of
31%) is primarily related to the following:
 
     - A valuation allowance recognized on a U.S. deferred tax asset generated
       from general and administrative expense incurred in the United States
 
     - A valuation allowance recognized on a U.K. deferred tax asset relating to
       non-deductible interest expense prior to achieving a consolidated tax
       position
 
     - Non-deductible amortization of goodwill resulting from the acquisition of
       Wessex
 
   
  WESSEX (PREDECESSOR COMPANY) -- SIX MONTHS ENDED OCTOBER 2, 1998
    
 
   
     Operating revenues for the six months ended October 2, 1998 were $233.8
million. Approximately 91% of these revenues relate to the sale of measured and
unmeasured water and wastewater services. Operating revenues from SC Technology
and other unregulated activities accounted for 5% and 4%, respectively, of total
operating revenues.
    
 
   
     Operations and maintenance expense for the six months ended October 2,
1998, was $61.7 million. Of this amount, $46.8 million relates to the cost of
supplying water and treating wastewater, including the costs of maintaining and
operating plant and equipment used in these processes. In addition, $10.9
million relates to the cost of the plants being installed by SC Technology.
    
 
   
     General and administrative expenses of $36.4 million for the six months
ended October 2, 1998 include $20.7 million incurred by Wessex in connection
with its acquisition by Azurix.
    
 
   
     Income tax expense for the six months ended October 2, 1998 was $28.4
million, which resulted in a 28% effective book tax rate compared to a statutory
tax rate of 31%. The primary reason for the variance from the statutory rate is
the effect of an enacted change in the statutory tax rate during the period from
    
 
                                       29
<PAGE>   35
 
   
31% to 30%, effective April 1, 1999. This was partially offset by the effect of
non-tax deductible expenses that were incurred during the period.
    
 
   
  WESSEX (PREDECESSOR COMPANY) -- YEAR ENDED MARCH 31, 1998 COMPARED TO THE YEAR
ENDED
    
  MARCH 31, 1997
 
     Operating revenues for the fiscal year ended March 31, 1998 increased by
$33.5 million, or 8.3%, when compared to the fiscal year ended March 31, 1997,
primarily as a result of a 4.6% increase in the pricing formula contained in the
Wessex license, effective April 1, 1997, which resulted in $17.9 million of
additional operating revenues. In addition, operating revenues from SC
Technology increased by $4.2 million due to a higher number of construction
projects in progress during the year ended March 31, 1998.
 
     Operations and maintenance expense for the year ended March 31, 1998
increased by $8.5 million, or 8.3%, when compared to the year ended March 31,
1997, primarily due to higher operating expenses from SC Technology due to a
higher number of construction projects in progress in the year ended March 31,
1998.
 
     General and administrative expense for the year ended March 31, 1998
decreased by $3.1 million, or 9.6%, when compared to the year ended March 31,
1997, primarily due to cost reduction measures implemented by Wessex, and costs
of $2.1 million incurred in the year ended March 31, 1997 related to an
unsuccessful attempt to acquire a third party.
 
     Depreciation and amortization expense for the year ended March 31, 1998
increased by $6.3 million, or 10.9%, when compared to the year ended March 31,
1997. Substantially all of this increase is due to property additions resulting
from Wessex's capital expenditure program.
 
     Equity earnings of affiliates for the year ended March 31, 1998 decreased
by $1.4 million, or 9.5%, when compared to the year ended March 31, 1997. This
decrease resulted from a lower sales margin due to increased competition, and
higher general and administrative expense related to the hiring of additional
sales staff.
 
     Net interest expense was $8.6 million for the year ended March 31, 1998, as
compared to net interest income of $10.2 million for the year ended March 31,
1997, primarily due to a reduction in the cash and cash equivalent position in
the current period as a result of the buy-back of its "B" and "C" classes of
ordinary shares in February 1997.
 
   
     Income tax and utility tax expense for the year ended March 31, 1998 as
compared to the year ended March 31, 1997, increased by $137.9 million primarily
as a result of a one-time tax levied in the year ended March 31, 1998 of $162.3
million. The effect of the utility tax was partially offset by a change in the
U.K. statutory tax rate from 33% to 31% during the year ended March 31, 1998,
which amounted to $22.6 million.
    
 
   
     The utility tax, introduced in the Finance (No. 2) Act 1997 and referred to
in the legislation as the Windfall Tax, was levied on privatized utilities
including the water and electricity sectors. It is a one-time tax in that the
legislation only relates to this assessment and new legislation would have to be
enacted for any additional windfall tax. In addition, the U.K. Government has
stated that it was a one-time tax. The calculation of the utility tax was based
on the profit after tax of Wessex for the average of the four years ended March
31, 1994, multiplied by a price to earnings ratio of nine. The resulting amount
was compared to the value of Wessex at the date of initial trading of its stock
in 1989, and the difference was deemed to be windfall profits and was taxed at a
23% rate.

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. Azurix has recently put in place a business
development effort requiring an increase in personnel to pursue and support
acquisition and privatization activity on a global scale. As of May 21, 1999,
Azurix had hired approximately 165 employees. The associated general,
administrative and operating expenses are approximately $15 million pre-tax on a
quarterly basis.
    
 
   
     Most of our operating revenues are subject to governmental regulation of
the rates that we may charge to our customers. The U.K. water regulator, the
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. In October 1998, the Director proposed an initial price cut for Wessex in
excess of 17.5% from 1999-2000 to 2000-2001, with prices gradually increasing
thereafter but remaining below the 1999-2000 levels in 2004-2005. Following this
proposal, the U.K. Government announced its decision to require greater capital
expenditures for water and wastewater companies for environmental improvements.
Subsequently, in its April 1999 business plan filed with the Director, Wessex
proposed stable prices from 1999-2000 to 2000-2001, with prices gradually
increasing to 18% higher than current levels in 2005, primarily to fund capital
expenditures mandated by the new environmental standards. The Director will
consider the business plan in his review. The Director has stated that he will
publish draft price limits in July 1999 with the final determination being made
in November 1999. These price limits may differ materially from the Director's
original proposal. Although we are unable to predict the precise outcome of the
current U.K. periodic review, if Wessex were required to cut its prices as
originally proposed by the Director, Wessex's regulated operating revenues,
which represent approximately 90% of Azurix's total operating revenues, would be
reduced by approximately 17.5% and its earnings would be reduced materially.
However, we would not expect that this would have a material adverse effect on
Azurix's financial position. At the time of the acquisition of Wessex, we took
into consideration the pending rate review in our valuation of Wessex.
    
 
   
     On February 2, 1999, Azurix granted options to purchase approximately 7.8
million shares of its common stock through an employee stock option plan. The
Stock Plan Committee of Azurix's Board of Directors determined that the exercise
price of $16.72 per share was fair market value at the date of grant. In making
this determination, the Stock Plan Committee considered factors such as the
close proximity of the grant date and the Wessex acquisition date and the
absence of any material developments in Azurix prior to the grant date. The
Board of Directors has authorized additional grants, effective as of the closing
of the offering, of options to purchase 0.7 million shares of common stock to
employees who recently joined Azurix and to non-employee directors of Azurix.
The exercise price of these additional options will be equal to the initial
public offering price. All stock options generally vest over three to five years
and will be exercisable for ten years after the date of grant. The future
exercise of these options will have a dilutive effect on basic earnings per
share.
    
 
   
     Azurix refinanced a portion of its existing debt in May 1999, which will
result in a one-time non-cash charge of $9.8 million ($6.9 million after-tax) in
the second quarter due to the write-off of deferred financing costs. We incurred
approximately $8.1 million in financing costs related to the new financing. See
"-- Recent Developments."
    
 
   
     In addition to the pending acquisition in the Province of Buenos Aires,
Argentina, we are continually evaluating potential acquisition opportunities
involving other water and wastewater assets, companies and water services
providers. The timing, size and success of these potential acquisitions cannot
be predicted. The completion of any one of these potential acquisitions could
have a significant impact on our business.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
     All of Azurix's cash flows for the period from inception to December 31,
1998 occurred in the fourth quarter following the Wessex acquisition. Cash flow
from operations totaled $4.4 million during the period
 
                                       31
<PAGE>   37
 
   
from January 29, 1998 to December 31, 1998. Related to its investment
activities, Azurix used $2,270.8 million, in addition to the issuance of $119.8
million of acquisition loan notes, to acquire ordinary shares of Wessex and
$63.2 million for capital expenditures incurred by Wessex. In addition, Azurix
received $337.9 million in proceeds from the sale of UK Waste. Cash provided by
financing activities during the period totaled $1,977.5 million, primarily
comprised of $1,600.2 million from the issuance of common stock and capital
contributions and a net increase in borrowings of $485.4 million, partially
offset by the redemption of the Wessex preference shares of $106.4 million. Cash
received from the issuance of common stock of $1.0 million and capital
contributions of $1,599.2 million are from Azurix's former parent company, Enron
Water (Holding) L.L.C.
    
 
   
     Azurix's cash flows from operations totaled $12.5 million during the three
months ended March 31, 1999. Cash used in investing activities during this
period was primarily comprised of capital expenditures of $74.5 million, the
acquisition cost of Azurix's interest in the Cancun concession of $13.5 million
and a loan made to the Cancun concession for $15.0 million. Cash provided by
financing activities of $105.1 million was primarily comprised of net borrowings
of $57.1 million and an advance from Enron of $48.0 million which was used to
fund the Cancun acquisition and the related loan and to fund general and
administrative costs incurred by Azurix to pursue acquisition and development
projects.
    
 
   
     At December 31, 1998, Azurix had a working capital deficit of $129.6
million. Approximately 60% of Azurix's operating revenues are derived from
customers whose billings are not based on the delivery of a measured volume of
service. These customers are billed semiannually in advance. Funds received in
advance as of December 31, 1998, where service has not been provided, totaled
$71.0 million and are reflected on the Consolidated Balance Sheet as deferred
income. This component of the working capital deficit does not require the
future use of cash but is recognized in income over the remaining service period
covered by the billings. The remaining working capital deficit is related to the
timing of cash payments. Excess cash, including funds received in advance, is
used to pay down short-term revolving bank credit facilities. The funds are
re-borrowed under these credit facilities when needed to pay current
obligations. At December 31, 1998, Azurix had available capacity, under its
existing credit facilities, to provide $91.5 million of working capital.
    
 
   
     At March 31, 1999, Azurix had a working capital deficit of $134.5 million.
Of this amount, $64.2 million is an advance from Enron that will be repaid from
the net proceeds from the offering. An additional $21.8 million is deferred
income that does not require the future use of cash as discussed above.
Management believes that cash flows from operations and available capacity under
credit facilities are sufficient to fund the working capital deficit.
    
 
   
     At December 31, 1998, Azurix, through Azurix Europe, had in place a senior
credit facility consisting of a term loan facility of $322.6 million and a
revolving credit facility of $575.3 million. The amounts outstanding at December
31, 1998 were $211.2 million under the term loan facility and $8.3 million under
the revolving credit facility. As a result, at December 31, 1998, Azurix had
total availability under the senior credit facility of $678.4 million,
consisting of $567.0 million under the revolving credit facility and $111.4
million under the term loan facility. Of the $567.0 million under the revolving
credit facility, $91.5 million was permitted, if required, to fund the working
capital deficit that existed at year end. The term loan capacity of $111.4
million was used at March 31, 1999 to secure a substantial portion of the
acquisition loan notes issued to Wessex shareholders in lieu of cash
consideration for their shares. On May 10, 1999, Azurix Europe entered into a
$686.0 million revolving credit facility. On May 13, 1999, Azurix Europe
borrowed approximately $75.9 million, of which approximately $67.8 million was
used to repay all of the remaining indebtedness outstanding on its former senior
credit facility and approximately $8.1 million was primarily used to pay fees
and expenses related to this facility. On May 14, 1999, Azurix borrowed $107.0
million under this revolving credit facility, primarily to fund the purchase of
Philip Utilities. Azurix intends to use a portion of the proceeds from the
offering, along with available cash, to repay all the indebtedness drawn under
the new senior credit facility. After the application of these proceeds, the
revolving credit facility has approximately $387.4 million of borrowing capacity
for acquisitions. It is expected that $365.7 million of this facility, along
with $72.9 million of proceeds from
    
 
                                       32
<PAGE>   38
 
   
the offering, will be used to fund the $438.6 million acquisition of an interest
in concessions in two regions of the Province of Buenos Aires, Argentina.
    
 
   
     The credit agreement with Enron will provide $180 million of liquidity to
fund general, administrative and operating expenses through December 2001. As of
May 21, 1999, no amounts were outstanding under this credit agreement. See
"-- Recent Developments." The principal amount outstanding under the credit
agreement will be limited to no more than:
    
 
   
     - $60 million at any time during calendar year 1999
    
 
   
     - $120 million at any time during calendar year 2000
    
 
   
     - $180 million at any time during calendar year 2001
    
 
   
     As of December 31, 1998, Azurix, through Wessex, was a borrower under
committed credit facilities that provided an aggregate $399.1 million for
general corporate purposes. As of December 31, 1998, these bank facilities were
completely drawn down. Wessex also had $24.9 million outstanding under
short-term uncommitted bank borrowings at December 31, 1998. On March 30, 1999,
Wessex issued $484.2 million principal amount of 10-year bonds. Wessex used
$448.4 million of the proceeds from the sale of the bonds to repay all
outstanding amounts under its former bank credit facilities as well as all
outstanding amounts under uncommitted credit facilities. Excess proceeds were
available for general corporate purposes. See "Description of
Indebtedness -- Indebtedness of Azurix Europe" for a detailed discussion of the
terms of the credit facilities and loan agreements.
    
 
   
     Azurix, through Wessex, maintains an ongoing asset replacement program
throughout its customer service areas in the United Kingdom based on an
expenditure plan submitted to the U.K. industry regulator. Wessex expects that
its projected capital expenditures of approximately $230 million for 1999 will
be financed with internally generated funds and from proceeds under long-term
and short-term borrowing arrangements. Included in this amount are contractual
commitments for capital expenditures to be incurred after December 31, 1998 of
$130.2 million. The projected capital expenditures consist primarily of the
following:
    
 
     - Approximately $135 million for wastewater projects, such as construction
       of wastewater treatment facilities and improvements to existing
       facilities
 
     - Approximately $45 million for water supply projects, such as construction
       of water treatment facilities and installation of water mains
 
     - Approximately $25 million for office space construction in the United
       Kingdom
 
   
     - Approximately $20 million related to information technology investment
    
 
FINANCIAL RISK MANAGEMENT
 
     Azurix is exposed to market risks, particularly changes in U.S. and
international interest rates and changes in currency exchange rates as measured
against the functional currencies in which it operates. Azurix engages in
hedging programs aimed at limiting the impact of significant and sudden
fluctuations, but there can be no assurance that such an approach will be
successful. Factors that could impact the effectiveness of its hedging programs
include the accuracy of revenue forecasts, volatility of the currency and
interest rate markets, and the availability of hedging instruments. Azurix
utilizes swap contracts to manage interest rate risk. Currency exchange rate
risk is the result of transactions that are denominated in a currency other than
the functional currencies in which we operate. The primary purpose of Azurix's
foreign currency hedging activities is to manage the volatility associated with
currency exchange rates. We manage these risks by utilizing derivative financial
instruments for non-trading purposes. Azurix enters into currency or interest
rate contracts for the sole purpose of hedging an existing or anticipated
exposure, not for speculation. Azurix's accounting policies for, and the
significant terms of, derivative financial instruments are described in Note 1
and Note 8, respectively, to the Consolidated Financial Statements.
 
                                       33
<PAGE>   39
 
     Azurix uses J.P. Morgan's RiskMetrics(TM) system to estimate the
value-at-risk of its financial instruments. Value-at-risk is a statistical
estimate of the loss that would result from changes in market prices.
Value-at-risk is based on volatility and correlation data provided by J.P.
Morgan, a statistical confidence level and an estimate of the time period
required to liquidate the positions in the various financial instruments. The
value-at-risk estimate was based on normal market conditions, a 95% confidence
level and a liquidation period between 30 days and 60 months, depending on the
type of financial instrument. At December 31, 1998, the value-at-risk estimate
for foreign currency and interest rate exposure was $0.7 million and $0.9
million, respectively. The value-at-risk estimate includes only the risk related
to the financial instruments that serve as hedges and does not include the
related underlying hedged item. Judgment is required in interpreting market data
and the use of different market assumptions or estimation methodologies that
will affect the estimated value-at-risk amount.
 
YEAR 2000
 
   
     The Year 2000 problem results from the use in computer hardware and
software of two digits rather than four digits to define the applicable year.
The use of two digits was a common practice for decades when computer storage
and processing was much more expensive than it is today. When computer systems
process dates both before and after January 1, 2000, two-digit year "fields" may
create processing ambiguities that can cause errors and system failures. For
example, computer programs that have date sensitive features may recognize a
date represented by "00" as the year 1900, instead of 2000, or may not recognize
the date February 29, 2000, as there was no February 29 in 1900. These errors or
failures may have limited effects, or the effects may be widespread, depending
on the computer chip, system or software, and its location and function.
    
 
   
     The effects of the Year 2000 problem are exacerbated because of the
interdependence of computer and telecommunications systems in the United States
and throughout the world. This interdependence applies to Azurix and Azurix's
suppliers, trading partners and customers and to governments of countries where
Azurix does business. This interdependence also applies to Enron, on which
Azurix relies for services as described under "Transactions with Enron, Atlantic
Water Trust and Marlin Water Trust."
    
 
  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 are conforming Wessex's Year 2000 efforts to
the Enron plan and are introducing this plan to our operations in Cancun.
    
 
     Central information systems, such as large mainframes and midsize computer
systems at Wessex and desktop or personal computers and computer networks, can
be vulnerable to Year 2000 problems. In addition, devices with chips embedded in
them, such as flow controllers and controllers for automated pumps, are
vulnerable to Year 2000 problems. Devices with chips embedded in them may be
used for many purposes, and finding all of them may be difficult, even with a
careful inventory and remediation process. In addition, we are concerned with
the systems of external entities over which we do not have control. Examples of
these systems include central information systems and embedded devices of our
suppliers and contractors, financial institutions, governments in locations
where we operate, customers and co-venturers.
 
   
     In general, the Enron Year 2000 plan adopted by Azurix includes phases of
awareness, inventory, remediation, verification and testing, and contingency
planning. These steps describe a process that continues to go in cycles. For
example, we will continue to refine our inventory of central information
    
 
                                       34
<PAGE>   40
 
   
systems and embedded devices until the early days and, if necessary, weeks of
January 2000, to identify Year 2000-related problems that require remediation.
    
 
   
     WESSEX. Under the Enron plan, Wessex will continue to:
    
 
     - Inventory its mission-critical computer hardware and software systems and
       embedded chips, i.e., computer chips with date related functions,
       contained in a wide variety of devices, that in turn are installed in a
       wide variety of equipment and that may fail to function or may function
       improperly before, on or after January 1, 2000
 
     - Assess the effects of Year 2000 problems on its mission-critical
       functions
 
     - Remedy to the maximum extent practicable material disruptions or other
       material adverse effects on its mission-critical functions, processes and
       systems
 
     - Verify and test the mission-critical systems to which remediation efforts
       have been applied
 
     - Attempt to limit the adverse effect of Year 2000 problems that cannot
       reasonably be remediated by January 1, 2000, including developing
       contingency plans to minimize Year 2000 problems that have not been
       identified or fixed by January 1, 2000
 
   
     Wessex has completed most of the stages of the Enron plan and should be
Year 2000 ready by July 31, 1999 as shown in the following table:

     Wessex has substantially finished identifying and assessing its
mission-critical central information systems and devices with embedded chips.
All of Wessex's internal information systems are Year 2000 ready. Wessex is
continuing to analyze, convert and test its mission-critical central information
systems and devices with embedded chips. In addition, Wessex has contacted all
outside entities on which it relies for mission-critical functions.
    
 
   
     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.
    
 
   
     Our Year 2000 program requires external entities to be ranked as
mission-critical, important or ordinary. External entities ranked as
mission-critical are expected to receive site visits by senior personnel from
Azurix's Year 2000 teams. In addition, the Azurix teams are expected to maintain
contact and receive status updates from the mission-critical entities throughout
1999 and, if necessary, into 2000. Non-mission-critical entities are to be
addressed as time permits. The purpose of this program is to identify key
entities that may not have adequately addressed the Year 2000 problem and to
mitigate Azurix's exposure
    
 
                                       35
<PAGE>   41
 
   
by developing appropriate contingency plans. Azurix recognizes that
comprehensive Year 2000 programs may not fully remediate all Year 2000 issues.
Therefore, we do not categorize any mission-critical entities as "Year 2000
ready."
    
 
   
     Wessex has received responses to its inquiries about Year 2000 readiness
and has contacted all outside entities on which it relies for mission-critical
functions. Among other things, Wessex asked each entity to demonstrate what the
entity did to support affirmations that the entity satisfied the British
Standards Institute protocol for Year 2000 readiness. Every entity with one
exception demonstrated that it satisfied this standard. The sole exception was a
communications common carrier that was not able to demonstrate that its
international connections satisfy or will satisfy Year 2000 readiness standards.
    
 
   
     Wessex's contingency plans assume that its mission-critical external
entities will experience Year 2000-related failures and disruptions. For
example, Wessex's contingency plans assume loss of electrical power and require
the installation of Year 2000 ready emergency generators to deal with this
possibility. Wessex expects that its initial contingency planning will be
completed by the end of June 1999 and will be followed by at least two rounds of
testing before September 30, 1999.
    
 
   
     MENDOZA. We do not have operational control of the Mendoza concession.
Therefore, we consulted with SAUR, the operator of the concession, to develop an
understanding of SAUR's Year 2000 efforts at Mendoza. SAUR is pursuing a Year
2000 plan for the concession with the following stages, which are shown with a
description of their current status and target completion dates:

     All internal information systems, both hardware and software, have been
assessed for Year 2000 readiness purposes. SAUR plans in 1999 to replace the
systems for accounting, budgeting and accounts payable and disbursements, for
measurement of water and wastewater flows and for supervisory control and data
acquisition. The customer billing, collection and customer support system
requires partial remediation to achieve Year 2000 readiness, and we understand
that SAUR expects to finish remediating the defective components by the end of
1999. All of the internal local area networks other than the servers have been
tested by SAUR and we understand they have been found to be completely Year 2000
ready. New servers for these networks have been installed but not yet tested to
ascertain Year 2000 readiness. SAUR will complete that testing before the end of
1999.
    
 
   
     The mission-critical systems at the Mendoza concession include business
systems, such as a customer interface system and a payroll system, and devices
with embedded chips such as flow meters and a supervisory, control, and data
acquisition system. Mission-critical external entities include the local
electrical utility for power to supply water pumps, the local telephone company
and local banks that function as collection agents. SAUR has not yet started to
visit its mission-critical external entities to obtain representations as to
their Year 2000 readiness. Before the end of 1999, we understand that SAUR
expects to complete visits with all its mission-critical external entities, with
the objective of obtaining representations as to their Year 2000 readiness, for
the purpose of formulating contingency plans to deal with Year 2000 disruptions
or other problems that may result from Year 2000-related problems that the
external entities experience. Although employees of SAUR plan to visit
mission-critical external entities, we cannot assure that the systems of these
external entities will be free from disruptions due to Year 2000 problems, and
SAUR cannot ensure that the Mendoza facility will be free from mission-critical
disruptions as a result. We anticipate that SAUR will include these
mission-critical external dependencies in its contingency planning.

     CANCUN. The Cancun concession is in the early stages of adopting and
implementing the Enron plan for Year 2000 readiness. The concessionaire will
inventory, assess, analyze, convert and test the Cancun systems for Year 2000
readiness and develop Year 2000 contingency plans to minimize Year 2000 problems
that have not manifested themselves or have not been corrected by January 1,
2000. The schedule for this implementation is as follows:

     With respect to internal information systems, 100% of our personal
computers have been tested and 56% of them will be replaced by July 1, 1999 to
achieve Year 2000 readiness. Two servers, which constitute all of the facility's
servers, will be replaced by July 1, 1999 with Year 2000 ready servers.
    
 
   
     Internal accounting and administrative software has been tested for Year
2000 readiness by the vendor, and the vendor has stated that it will supply its
written certification of Year 2000 readiness by the end of May 1999. Invoicing
software is currently being upgraded by the vendor to achieve Year 2000
readiness, and we have been informed by the vendor that the upgraded Year 2000
ready software will be installed and functioning by the end of May 1999. Human
resources software is not mission-critical, and we expect to test it for Year
2000 readiness by the end of June 1999. This software will be upgraded or
replaced as necessary to achieve Year 2000 readiness by December 1, 1999.
    
 
   
     We have identified the following as mission-critical external entities for
the Cancun facility: the electrical utility, Mexico's nationwide communications
common carrier, local banks, fuel suppliers for the facility's trucks and the
chlorine supplier for the facility. All these entities have been contacted.
Among these entities, we have visited two local banks to date and expect to
visit all other mission-critical entities by the end of August 1999. The
electrical utility has referred us to its Internet page for a description of the
utility's Year 2000 plan, which the utility expects to complete by July 30,
1999. The communications common carrier has informed us verbally that it is Year
2000 ready, and we have been told that it will confirm this advice in a letter
that we expect to receive by the end of July. We deal with 12 local banks, and
only one of these banks has advised us verbally that it is Year 2000 ready. The
other banks have asked us to inquire again later, with no definite time
specified, regarding their Year 2000 readiness, and we plan to contact them
again before the end of June 1999. The fuel suppliers for our trucks have
verbally stated that they are Year 2000 ready, and we expect written
confirmation from each of them by the end of June 1999. The chlorine supplier
verbally advises us that they are Year 2000 ready, but have not offered written
confirmation. Our contingency plan regarding chlorine is to stock three months'
supply. That supply will be ordered in May 1999, with a delivery date to be
determined, but that will probably be within 60 days of the order.
    
 
   
     We believe that Wessex's and the Cancun concession's mission-critical
systems will be Year 2000 ready substantially before January 1, 2000. However,
unforeseen circumstances could arise during the implementation of the Enron plan
that could adversely affect Enron's, Wessex's or the Cancun concession's
mission-critical functions, thereby disrupting or materially adversely affecting
Azurix's business.
    
 
   
     PHILIP UTILITIES. Although Philip Utilities was preparing for Year 2000 at
the time we acquired it, Azurix will require Philip Utilities to adopt Enron's
Year 2000 plan. At this stage in our management of Philip Utilities, it is too
early for us to predict when Philip Utilities will complete the inventory,
assessment, conversion, testing, implementation and contingency planning stages
as required by the Enron Year 2000 plan that we adopted. However, we expect that
Philip Utilities will commence work on all of these tasks in May or June 1999,
and will complete initial work on these tasks by the end of December
    
 
                                       37
<PAGE>   43
 
   
1999, if not earlier. Testing, implementation, and contingency planning will
continue in cycles through the end of 1999 and into 2000 as necessary.
    
 
   
     Philip Utilities' internal information systems are not mission-critical
and, in any event, we anticipate that they will be remediated for Year 2000
purposes by the end of 1999. Other computer systems and systems using devices
with embedded chips are mission-critical because they are part of water or
wastewater systems operated by Philip Utilities. We anticipate that Philip
Utilities will inventory and remediate these systems and test them for Year 2000
purposes before the end of 1999. Further, Philip Utilities will develop
contingency plans to deal with Year 2000 problems that are not found and fixed
before the end of 1999.
    
 
   
     Azurix's Year 2000 program requires that external entities be ranked as
mission-critical, important or ordinary. External entities ranked as
mission-critical are expected to receive site visits by senior personnel from
Philip Utilities' Year 2000 teams. In addition, the Philip Utilities teams are
expected to maintain contact and receive status updates from the
mission-critical entities throughout 1999 and, if necessary, into 2000.
Non-mission critical entities are to be addressed as time permits.
    
 
   
     The purpose of this program is to identify key entities that may not have
adequately addressed the Year 2000 problem and to mitigate Philip Utilities'
exposure by developing appropriate contingency plans. Azurix recognizes that
comprehensive Year 2000 programs may not fully remediate all Year 2000 issues.
As such, Philip Utilities will not categorize any mission-critical entities as
"Year 2000 ready." In any case, Philip Utilities will develop contingency plans
for all mission-critical entities.
    
 
   
     We have reviewed the most reasonably likely worst case scenarios that
Philip Utilities may face. Although unlikely, these possibilities conceivably
could include failure of computer systems or devices with embedded chips that
are used to control water or wastewater systems. In some cases, these systems
are operated by Philip Utilities. In other cases, Philip Utilities installed or
furnished consulting services with respect to these systems. In most, if not
all, cases, the computer controls for these systems can be overridden and the
systems can be operated manually. Therefore, the potential failure of the
computer control systems would be important only if the plant's operators failed
to observe that the computer systems failed. This is possible though unlikely.
    
 
   
     Other possible worst case scenarios involve a failure of electrical
utilities or communications common carriers that furnish electricity and
communications services to these facilities. This kind of failure could disrupt
or interrupt the functioning of water or wastewater plants. Philip Utilities
will develop contingency plans for these possible failures. However, if
electrical power is unavailable to a water or wastewater facility for a period
greater than several hours, Philip Utilities might not be able to keep the
facility functioning. This could cause untreated or improperly treated water and
wastewater to be discharged into waterways. This in turn could create potential
legal liability for Philip Utilities and otherwise have a material adverse
effect on Philip Utilities' business, similar to the adverse effects described
for Azurix. We recognize that the widespread unavailability of electrical power
would cause disruptions that would not be unique to Philip Utilities.
    
 
   
     Based on our initial review, Philip Utilities has not to date incurred
material Year 2000 costs, and we do not anticipate Philip Utilities' 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 Philip Utilities' business will
not be materially adversely affected by Year 2000 issues.
    
 
   
     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.
    
 
   
  ENRON
    
 
   
     Enron advises us that the internal information systems at Enron on which
Azurix will rely either are Year 2000 ready or are expected to be Year 2000
ready by June 30, 1999. Enron further advises us that it is in the process of
making contact with entities external to Enron, among them electrical utilities
and
    
                                       38
<PAGE>   44
 
   
telecommunications common carriers, that are critical to the operating mission
of these Enron internal information systems, and that this process will continue
throughout 1999. Enron is aware that, despite the belief of these
mission-critical external entities that they are Year 2000 ready, that readiness
may be compromised by hidden remediated computer code, embedded chips and the
possible Year 2000-related failures of other entities on which the external
entities in turn depend. Therefore, Enron is developing contingency plans to
deal in a reasonable way with these possible interrelated failures. These
contingency plans will continue to be refined in cycles throughout the remainder
of 1999.
    
 
   
  OUTSIDE ENTITIES THAT ARE NOT YEAR 2000 READY
    
 
   
     Azurix realizes that Year 2000-related disruptions and their consequent
adverse effects remain a possibility. We will not rely entirely on
mission-critical external entities' assurances of Year 2000 readiness because
these entities are subject to failures resulting from the problems of embedded
chips, re-coding errors in remediated code and the potential effects of attempts
at sabotage early in the new year. Because of this potential for disruption and
material adverse consequences, Azurix never considers an external entity to be
"Year 2000 compliant" or "Year 2000 ready." Further, neither Azurix nor Enron
can ensure that an external entity is, or will be, Year 2000 ready. Instead,
Azurix and Enron will deal with the possibility that mission-critical external
entities will not be Year 2000 ready by developing reasonable contingency plans.
This contingency planning will continue in cycles throughout 1999. The
contingency plans will be designed to deal with the reasonably likely effects on
our operations that could result from material outages or other Year
2000-related disruptions to these external entities. Therefore, the plans will
be designed to facilitate identification and remediation of Year 2000 problems
that may manifest themselves after January 1, 2000.
    
 
  COSTS TO ADDRESS YEAR 2000 ISSUES
 
   
     As of May 20, 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 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.
    
 
  YEAR 2000 RISK FACTORS
 
     We plan to satisfy applicable regulatory requirements with respect to Year
2000 readiness. However, failure to comply with such requirements may cause a
regulatory authority to order the cessation of our operations, which could have
a material adverse affect on our business.
 
     As the Year 2000 approaches, there will be increased competition for people
with the technical skills necessary to deal with Year 2000 problems. While we
intend to recruit and retain a sufficient number of people with those skills,
the shortages of skilled personnel could prevent us from doing so. In addition,
we may face shortages of other resources, such as Year 2000 ready computer chips
or components. These shortages might delay or otherwise impair our ability to
assure that our mission-critical systems are Year 2000 ready.
 
     We will rely on Enron for services that involve computer processing. These
Enron systems are mainframe systems used for functions such as asset management,
accounting and human resources. Enron believes that its mission-critical systems
will be Year 2000 ready substantially before January 1, 2000. In
                                       39
<PAGE>   45
 
addition, we believe that Wessex's mission-critical systems will be Year 2000
ready substantially before January 1, 2000. However, unforeseen circumstances
could arise during the implementation of the Enron plan that could adversely
affect Enron's or Wessex's mission-critical functions, thereby disrupting or
materially adversely affecting Azurix's business.
 
   
     We are taking reasonable steps to identify, assess and, where necessary,
replace devices containing embedded chips. Despite these efforts, we anticipate
that we will not be able to find and replace all the devices with embedded chips
or embedded chips in our systems. Further, we anticipate that outside entities
on which we depend will also not be able to find and replace all devices with
embedded chips or embedded chips in their systems. Some of the embedded chips
that fail to operate or that produce improper results may create system
disruptions or failures. Some of these disruptions or failures may spread from
the systems in which they are located to other systems. These failures may have
adverse effects upon our ability to maintain safe operations and may also have
adverse effects upon our ability to serve our customers, to comply with
environmental statutes and regulations, and to otherwise fulfill contractual and
other legal obligations. The embedded chip problem is widely recognized as one
of the more difficult aspects of the Year 2000 problem. Therefore, the possible
adverse impact of the embedded chip problem is not, and will not be, unique to
Azurix.
    
 
   
     The external entities we are contacting include suppliers, customers,
financial institutions, and governmental entities. We intend to meet with many
external entities that are mission-critical to Azurix for Year 2000 purposes.
However, we cannot in any way ensure that these external entities will be Year
2000 ready, nor can we place complete reliance on any assurances, written or
oral, from these entities that they expect to be Year 2000 ready.
    
 
     We cannot assure that suppliers upon which we depend for essential goods
and services will test their mission-critical systems in a timely manner.
Failure or delay by all or some of these entities, including U.S. and foreign
governments or governmental authorities, to assess their Year 2000 readiness
could create substantial disruptions having a material adverse effect on our
business.
 
     We have reviewed the most reasonably likely worst case Year 2000 scenarios
we may face. Analysis of these scenarios has led us to contemplate the following
possibilities that, although unlikely, could conceivably occur:
 
     - Widespread failure of electrical, gas and other utilities serving us
       domestically and internationally
 
     - Widespread disruption of communications
 
     - Disruption of transportation services for us and our employees,
       contractors, suppliers and customers
 
     - Disruption to our ability to gain access to, and remain working in,
       office buildings and other facilities
 
     - The failure of substantial numbers of our mission-critical information
       systems, including both hardware and software necessary to control
       operational facilities such as water and wastewater treatment facilities
       and distribution and collection systems
 
     We could face substantial claims by governments, governmental authorities
or customers, as well as loss of revenues, due to service interruptions,
violations of environmental regulations, inability to fulfill contractual
obligations, inability to account for obligations and increased expenses
associated with litigation, harm to persons or to tangible property, violation
of environmental regulations, stabilization of operations following system
failures and the execution of contingency plans. We could also experience an
inability by customers and others to pay, on a timely basis or at all,
obligations owed to us. In addition, we could face claims of damage to persons
or property as the result of improperly treated water or wastewater. Under these
circumstances, there would be a material adverse effect on revenues and
operations. However, this effect can not be quantified at this time. Also, the
cumulative effect of Year 2000 failures in the United States and internationally
could have a substantial adverse effect on the domestic and worldwide economy.
 
                                       40
<PAGE>   46
 
     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

                     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. As an alternative to a 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 build-own-operate and
       build-own-transfer projects. In both a build-own-operate and a
       build-own-transfer project, the private party builds, owns and operates
       the asset. In the case of a build-own-transfer project, the private party
       then transfers the asset back to the government after a fixed term,
       usually 15 to 25 years but often longer. The build-own-operate or
       build-own-transfer contract describes the project and its services, as
       well as the revenues the private party will receive for the services the
       asset provides.
    
 
     - LEASES. Under a lease, a government turns over control of the system for
       a fixed period but, unlike in a concession, the government retains much
       of the economic risk. In France, most municipalities use a type of lease
       called an affermage, which is also used in many former French colonies.
 
                                       42
<PAGE>   48
 
     - OPERATIONS AND MANAGEMENT CONTRACTS. Sometimes a government will ask a
       private party to operate its system on a day-to-day basis, but will keep
       most of the economic risk relating to the system. The term of the typical
       operations and management contract is five to ten years. These contracts
       are common in the United States. See "Business -- The Global Water
       Industry--Trend Toward Government Outsourcing Through Private Sector
       Participation -- North America."
 
   
     - OUTSOURCING PARTICULAR SERVICES. A government also may ask private
       parties to provide specific services to a government-operated water or
       wastewater system. Examples of these services include billing,
       construction projects and residuals management. The service provider
       typically takes no risk for the system as a whole, only for the
       particular services it provides. See "Business -- The Global Water
       Industry -- Outsourcing Opportunities in the Municipal and Industrial
       Services Markets."
    
 
SELECTED AWARDED WATER AND WASTEWATER PRIVATIZATIONS
 
   
     The following is a list of selected water and wastewater privatizations in
Europe, North America, Latin America, the Caribbean, Asia and the Pacific Rim
that have been awarded during the past several years. The majority of these
privatizations have been in the form of concessions, build-own-transfers or
leases, except in North America, where private parties have primarily entered
into operations and management contracts. Except as otherwise indicated in the
notes to the following table, the estimated size of these awarded privatizations
is taken from the October 1998 edition of Public Works Financing. The estimated
size for operations and management contracts represents aggregated fees over the
term of the contract. The estimated size for build-own-transfer projects
represents construction costs. The estimated size for concessions represents
total project costs.

                                    BUSINESS
 
   
     Azurix is a global water company engaged in the business of acquiring,
owning, operating and managing water and wastewater assets, providing water and
wastewater related services and developing and managing water resources. Enron,
one of the world's leading integrated natural gas and electricity companies,
formed Azurix to pursue opportunities in the global water industry. Enron
incorporated the company now called Azurix as a shell company on January 29,
1998. Azurix's first significant step was to acquire Wessex, a water and
wastewater company based in southwestern England, for $2.4 billion on October 2,
1998. Wessex was recognized in December 1998 by the Office of Water Services,
the industry regulator for England and Wales, as the most efficiently operated
water and wastewater company in England and Wales. Following our acquisition of
Wessex, we began implementing our global business strategy.
    
 
   
     Our asset portfolio also includes interests in long-term water concessions
in the Province of Mendoza, Argentina and in Cancun, Mexico. In addition, we
acquired Philip Utilities Management Corporation, a water and wastewater
services company with operations in the United States and Canada on May 18, 1999
for $106.3 million. Philip Utilities provides operations and management,
engineering, residuals management and underground infrastructure development
services for municipal water and wastewater facilities in North America. On May
18, 1999, we were notified that, subject to final confirmation, we will be
awarded an interest in long-term water and wastewater concessions in two regions
of the Province of Buenos Aires, Argentina, at an aggregate price of $438.6
million. We have made each of these investments through one or more
subsidiaries, which will be our approach as we pursue our worldwide growth
strategy.
    
 
   
     On a pro forma basis, as adjusted for the offering, assuming the Wessex
acquisition occurred on January 1, 1998, and including our investment in the
Mendoza concession from the date of our investment, but excluding the Cancun,
Philip Utilities and Buenos Aires transactions, we had operating revenues of
$464.2 million, EBITDA of $298.1 million and net income of $91.1 million for the
year ended December 31, 1998. As of March 31, 1999, on a pro forma basis as
adjusted for the offering, Azurix had total assets of $3,544.4 million. To date,
all of our operating revenues have come from Wessex, and substantially all of
our operations have been conducted by Wessex.
    
 
   
     The following table represents the operating revenues contributed by each
of the service categories of our business for the periods indicated, although
most of the contributions occurred after the date of the Wessex acquisition:

     We are aggressively pursuing additional water and wastewater transactions
in Europe, North America, Latin America, the Caribbean, the Middle East, Africa,
Asia and the Pacific Rim. These include upcoming concessions in Berlin, Germany
and Santiago, Chile as well as other upcoming privatizations identified in this
prospectus and various privately negotiated transactions. We are also
continually evaluating potential acquisitions of companies owning water and
wastewater assets or providing water related services. The timing, size and
success of any of these potential acquisitions cannot be predicted. The
completion of any one of these acquisitions could have a significant impact on
our business.
    
 
     Our experienced management team from Enron, Wessex and other water and
wastewater systems, and multinational companies provides us with the experience
necessary to compete successfully in the global water industry. We are
transferring the skills that Enron has successfully applied in developing,
financing,
 
                                       46

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

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

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

privatizations expected in North America.

     LATIN AMERICA AND THE CARIBBEAN. The pace of infrastructure privatizations
in Latin America and the Caribbean 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 wastewater privatizations expected in Latin America
and the Caribbean.

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

     ASIA AND THE PACIFIC RIM. In Asia, the recent financial crisis and ongoing
economic uncertainty may be limiting private investment in the water sector.
Prior to the economic downturn in Asia, water concessions had been granted in
Indonesia, Malaysia and the Philippines. In China, municipal water agencies have
entered into build-own-transfer arrangements with Western companies for water or
wastewater treatment plants through auctions and negotiation. The following is a
list of selected upcoming water and wastewater privatizations expected in Asia
and the Pacific Rim.

  OUTSOURCING OPPORTUNITIES IN THE MUNICIPAL AND INDUSTRIAL SERVICES MARKETS
 
     We believe that municipal governments and industrial companies in North
America and Western Europe, in particular, will increasingly seek to outsource
the management of their water and wastewater systems to private parties with the
operating experience and capital to provide reliable services, to comply with
more stringent regulatory requirements for water quality and environmental
protection and to reduce uncertainty in financing these operations. To comply
with stricter environmental and drinking water quality standards, municipalities
will incur increased labor costs for treatment, higher monitoring and equipment
maintenance costs and increased costs of disposing of biosolids. Federal funding
grants to help municipalities meet their financial needs have declined over
time, leaving municipal wastewater authorities facing serious budgetary
challenges. Private sector outsourcing can include any combination of design,
financing, construction, ownership or operation of a facility; administrative
services such as metering, billing, collection or maintenance; and applying
process engineering technologies such as biosolids filtration, clarification,
purification, separation, drying and disposal.
 
     Industrial companies are also experiencing rising costs related to their
water and wastewater needs. The chemical, refining, pharmaceutical, high
technology, food and beverage, paper and pulp, steel, automobile and energy
industries have large water supply and wastewater treatment requirements. These
industries require pure water for their operations and produce effluents that
must be treated before being released into normal wastewater systems or being
discharged directly into the environment. Most industrial wastewater needs to be
pre-treated and environmental laws prohibit the direct discharge of wastewater
into the environment without a permit. Many industries treat and dispose of
their own wastewater because the relatively concentrated wastes from these
industries frequently cannot be discharged into the public sewer system and
on-site treatment is usually less expensive.
 
     These industrial companies must invest large amounts of capital in their
water and wastewater treatment and distribution assets. By outsourcing the
management of these assets to third parties, these companies may reduce the
uncertainty associated with expenditures required by changes in water quality
standards and environmental regulations. Obtaining landfill, storage and
incineration capacity to dispose of the residue from the wastewater treatment
process is a major component of providing industrial wastewater services, and
may involve procuring long-term capacity of specially lined or hazardous waste
landfills.
 
     The services to be provided to municipal and industrial customers generally
fall into three main categories:
 
     OPERATIONS, MANAGEMENT AND ENGINEERING. Over the past few years, large
cities and industrial companies have reduced costs by outsourcing the design,
construction, operation or maintenance of their water and wastewater assets to
private sector service providers. Many of these service providers have
consolidated and the market is much less fragmented than either the residuals
management or the underground infrastructure markets. Consequently, competition
for major contracts for the largest cities in the United States has been
significant. Although some companies have focused on providing services to small
to medium sized municipalities and large industrial firms, many of these
companies lack the financial capacity or risk management capability to purchase
water and wastewater assets from their industrial customers or to qualify on
their own as the operators and managers of their customers' facilities.
According to the May/June 1998 issue of Environmental Business Journal, the fees
associated with providing contract operations and consulting, design engineering
and maintenance services to customers in the municipal and industrial markets in
the United States are estimated to have exceeded $5.5 billion for 1997, and are
expected to continue to grow.
 
   
     RESIDUALS MANAGEMENT. Managing the biosolids that result from municipal and
industrial wastewater represents a large component of the cost of wastewater
treatment. Increasingly stringent effluent discharge standards are resulting in
a significant increase in the quantity of residuals. At the same time,
environmental regulations are limiting waste disposal options. For example,
ocean dumping of biosolids has been banned in the United States and the European
Economic Area, increasing costs for managing residuals in these regions. In
addition, environmental regulations are requiring firms to provide beneficial
reuse solutions. Incineration, landfilling, land application and producing
compost are becoming the only
    
                                       52
<PAGE>   58
 
   
available disposal options in many countries and have inspired a number of new
disposal and reuse technologies. These options are themselves the subject of
increasingly stringent environmental regulation. Certain applications can turn
biosolids from waste into a substance that can be sold as soil conditioner or
that can be burned as fuel. These technologies create a product with market
value and provide an environmentally attractive alternative to the increasingly
expensive and scarce disposal options of incineration and landfilling.
    
 
     Residuals management companies provide services to local and state
agencies, municipalities and private companies. Specific services include the
transportation, treatment, site monitoring, disposal and environmental
regulatory compliance services associated with biosolids and wastewater
disposal. These companies provide a variety of residuals management options to
prospective customers who seek alternative methods of biosolid treatment. Not
all methods can be profitably and practically applied in all geographic areas
due to the specific nature of the terrain and agriculture in the region and the
local biosolid content.
 
     We estimate that 55% of biosolids produced in the United States are
recycled, and we anticipate that recycling of biosolids will continue to grow
over the next decade. As recycled uses of biosolids continue to increase, we
believe that larger and more sophisticated companies will have opportunities to
create value through economies of scale and scope by providing new solutions to
these problems.
 
   
     UNDERGROUND INFRASTRUCTURE REMEDIATION AND DEVELOPMENT. We estimate that
over half of the approximately $275 billion of capital that the EPA estimates
will be spent in the United States during the next 20 years will be spent on
repairing, replacing and developing the nation's underground water and
wastewater infrastructure.
    
 
     Much of the cost associated with the repair, replacement and development of
underground infrastructure is attributable to the lost revenues resulting from
the disruption of service associated with open cut excavation. During the past
decade, advances in the oil and natural gas industry have been used in the water
industry, enabling the repair of underground infrastructure without open cut
excavation. Trenchless technologies such as horizontal drilling, tunneling,
grouting and pipe lining enable the repair and replacement of water
infrastructure with a fraction of the disruption associated with traditional
open cut excavation.
 
     Currently, small local civil engineering firms and contractors perform most
of the trenchless underground infrastructure work. As the size of these projects
grows and the capital requirements and sophistication of these newer
technologies increase, we believe larger, better capitalized and more
sophisticated firms who hold experience in the oil and gas industry will have a
competitive advantage in obtaining this business. We expect that the underground
water and wastewater infrastructure market for the municipal market in the
United States will grow during the next decade.
 
  WATER RESOURCE DEVELOPMENT AND MANAGEMENT
 
     We believe that the management of aquifers and other water resources and
the storage and transportation of water offer important opportunities for
business development. In many regions of the world, such as parts of North and
South America, the Middle East and many island nations, lack of abundant water
resources is a critical issue. Governments, which historically have been
responsible for developing and managing water resources, are now seeking private
sector assistance to address their water resource issues due to the operational,
technical and financial expertise required to operate, build and fund these
capital intensive projects.
 
     In many countries, including the United States and China, water consumption
is mainly driven by patterns of population movements and industrial and urban
development. In parts of the United States, increases in water demand resulting
from large population shifts to the sunbelt, multi-year droughts and
irrigation-intensive agriculture have resulted in consumption that exceeds the
natural rate of replenishment. This has led to large scale diversions of surface
water through dams and reservoirs and to diminished groundwater supply. In
China, rapid economic growth in the Southern provinces (primarily the Guandong
 
                                       53
<PAGE>   59
 
   
and the Shanghai areas) has significantly increased demand for water.
Drinking-quality water now used in agriculture may need to be diverted to
population centers.
    
 
     In light of these factors, industry participants are focusing new efforts
on means of extracting, managing, storing and transporting water resources as
efficiently as possible. The large amount of capital required and the inability
of local governments to fund these needs compound the difficulties in developing
and managing water resources. Transporting water over long distances to urban
areas requires canals, aqueducts, underground pipelines and/or pumping stations.
These are typically large infrastructure projects requiring significant
development, construction, operational and financial expertise.
 
  COMPETITION
 
     Participants in the global water market face significant challenges,
including qualifying for the bidding process, obtaining and demonstrating
operating experience and management depth, accessing capital, obtaining and
demonstrating expertise in managing international infrastructure projects,
identifying and evaluating transactions and assessing and mitigating risks,
especially operational, political and regulatory risks. As a result, only a
small number of companies currently compete globally in the water and wastewater
privatization market.
 
   
     Two French companies, Suez Lyonnaise des Eaux and Compagnie Generale des
Eaux, a subsidiary of Vivendi, currently are recognized as the leading
competitors in the international water and wastewater market. According to Suez
Lyonnaise des Eaux, it serves an aggregate population of approximately 77
million for water and 52 million for wastewater. According to Vivendi, Compagnie
Generale des Eaux serves an aggregate population of approximately 80 million for
water and 30 million for wastewater. These two companies are significantly
larger than the next group of international competitors, the largest of which
serves an aggregate population of approximately 32 million. These smaller
competitors include privatized water and wastewater companies from the United
Kingdom and some smaller French and Spanish companies. We are a new competitor
in the international water and wastewater market, and we currently serve an
aggregate population of approximately four million. Some construction companies
also bid on water and wastewater projects, more often on build-own-transfer
projects than on concessions.
    
 
   
     In the United States, the water and wastewater industry is highly
fragmented, with over 55,000 public and private water entities serving
approximately 90% of the nation's population. Of this number, approximately
31,000 are investor owned and the rest are publicly owned, generally by local
municipalities. Most of these entities serve only a single community or region.
Only eight publicly traded water and wastewater companies have market
capitalizations over $200 million, and only three have market capitalizations
over $500 million. Several of these publicly traded companies have become active
consolidators by acquiring the small private and public investor owned utilities
that operate in markets contiguous to or near their own. Of the three largest
consolidators, none has more than a 3% market share in the United States, and
these three combined serve only 6% of the nation's customers. In addition,
several electric utilities have begun to acquire municipally owned water
distribution companies in the United States. Many companies compete in the
United States for municipal service contracts and industrial outsourcing
opportunities, including subsidiaries of the French and U.K. water companies.
    
 
   
     In the United Kingdom, the water industry has achieved approximately 98%
population coverage. The 10 water and wastewater authorities in England and
Wales were privatized in 1989 to form 10 water and wastewater companies
operating in geographically discrete regions. Wessex has a virtual monopoly over
water supply and wastewater services in its licensed region, with the exception
of the cities of Bristol and Bournemouth and a small area of rural Wiltshire,
where three companies provide water and Wessex provides wastewater services.
There is some limited direct competition. For example, other companies may apply
to the industry regulator for a so-called "inset appointment" to serve
particular areas within Wessex's or any other licensee's service area. Inset
appointments may be granted for the supply of 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
    
 
                                       54
<PAGE>   60
 
   
area to be transferred to another company or potential company. Historically,
very few inset appointments have been granted in England and Wales. This may
change in the future as the U.K. Government and the Director General of Water
Services seek to increase competition. The Director has announced a future work
program that includes new initiatives to extend competition. These include
lowering the threshold for inset appointments, promoting competition in new
connections, facilitating common carriage and use of competition law powers.
Wessex does have one inset appointment within its territory resulting from the
privatization of water supply activities formerly provided by the Ministry of
Defence. Wessex chose not to pursue this project because of unacceptable
contract terms. The Chancellor of the Exchequer announced in March 1999 that the
Government intends to study ways to increase competition in the United Kingdom's
water sector. We cannot predict what changes, if any, the Government will adopt
to promote competition. See "-- Existing Azurix Assets -- Wessex" and
"Regulatory Matters -- U.K. Regulatory Matters -- Changes to Regulatory Regime."
    
 
OUR COMPETITIVE STRENGTHS
 
     We have several competitive strengths that should enable us to compete
successfully in the global water industry.
 
  EXPERIENCED MANAGEMENT AND BUSINESS DEVELOPMENT TEAMS
 
   
     Although our company was recently formed, we have a group of experienced
managers from long-established companies, including Enron, other multinational
companies, Wessex and other water and wastewater companies. Our management team
has extensive experience in competing for, developing and operating
infrastructure projects worldwide and years of experience in managing water and
wastewater companies primarily in the United Kingdom and also in the United
States. Many of our executives were actively involved in developing and managing
natural gas and power projects for Enron in the United States and around the
world. Enron is one of the world's leading integrated natural gas and
electricity companies with a market capitalization of approximately $28 billion.
Rebecca Mark, chairman and chief executive officer of Azurix and a vice chairman
of Enron, leads the Azurix team in implementing its global water strategy.
During her tenure at Enron, Ms. Mark was responsible for the successful
development of natural gas and power projects worldwide. Beginning with Enron's
first international power project in Teesside, England in 1989, Ms. Mark led the
team that developed gas and power projects around the world with total estimated
capital costs exceeding $10 billion.
    
 
   
     Our senior executives are complemented by a group of experienced business
developers who identify opportunities in the global water industry. We believe
that the collective experience of our management and business development teams
will enable us to compete successfully for public tenders. Since our formation,
we have qualified for bidding on numerous pending privatizations in Europe,
Latin America and the Middle East. Of the 14 privatizations in which we have
actively participated, only one final award has been made. In this bid for the
concession in Valparaiso, Chile, we were second to the winning bidder. We were
recently notified that, subject to final confirmation, we will be awarded
concessions for two regions of the Province of Buenos Aires, Argentina. We are
also currently one of the three finalists for the partial privatization of the
Berlin, Germany water and wastewater system. In addition, we have successfully
identified and closed the privately negotiated Cancun and Philip Utilities
transactions.
    
 
     Our management team will build upon its extensive experience and knowledge
from Enron, Wessex, other water and wastewater systems and other multinational
companies to provide us with the necessary skills to compete effectively in the
global water industry. Although most of our management team's experience in the
water and wastewater industry has been primarily in the United Kingdom and the
United States, we believe that our management team has the requisite operating
experience and management depth to identify and evaluate potential water and
wastewater projects, to qualify for bidding on projects in
 
                                       55
<PAGE>   61
 
many countries throughout the world, to access capital and to develop and manage
projects. Our management team has the ability to:
 
     - Mobilize the array of resources needed to enter competitive bids for
       concessions tendered in privatizations
 
     - Develop projects requiring construction of new facilities in developed
       and emerging countries
 
     - Meet the challenges of "fast-track" projects to be brought on-line within
       12 to 18 months
 
     - Execute major acquisitions
 
     - Operate regulated companies, including managing their tariff and other
       regulatory issues
 
   
     - Apply innovative financing and risk management strategies in markets
       worldwide
    
 
     We expect to apply many of the same disciplined techniques to analyze
projects and mitigate risks that Enron has developed in its own worldwide
activities. In identifying and quantifying the risks and value of a transaction,
these processes require an analysis of the engineering, operational, regulatory,
financial, economic, structural, legal, insurance, tax and accounting
implications of the transaction. These analytical skills will competitively
position us in the identification, evaluation, development, financing and
acquisition of worldwide water and wastewater projects and in the provision of
associated services.
 
  WESSEX OPERATING EXPERIENCE AND TECHNICAL EXPERTISE
 
     From Wessex, we have obtained the operating experience, research skills and
technical expertise necessary to evaluate potential water projects, to qualify
for bidding on water projects in many countries throughout the world, to build
transition and operating teams for new acquisitions and to manage existing and
new water assets. Wessex supplies approximately 400 million liters of water per
day to a population of approximately 1.1 million and treats on average 484
million liters of wastewater per day from a population of approximately 2.5
million. In December 1998, the water industry regulator for England and Wales
rated Wessex the most efficiently operated privatized water and wastewater
company. Wessex's management team has been in place since the privatization of
the U.K. water industry in 1989. For a discussion of Wessex, see "-- Existing
Azurix Assets -- Wessex."
 
   
     Wessex uses advanced treatment techniques, increased automation of
operations and services and state-of-the-art control and monitoring systems that
are designed to ensure consistently high standards at low cost. Since its
privatization, Wessex has improved levels of quality and standards of service,
providing reliable water supplies without requiring any water usage
restrictions. It has delivered this high quality service while reducing
operating costs and delivering capital improvements below budgeted amounts. In
addition, Wessex has developed extensive performance data that will be used for
benchmarking purposes in Azurix's operations around the world.
    
 
   
     We will also benefit from Wessex's experience with meeting mandated capital
expenditure targets through the use of standard designs, the cost-effective
management of major projects and in-house process and concept design. In
addition, the use of local contractors and detail designers as well as
appropriate technology and efficient procurement are key factors in capital
expenditure management that have benefited Wessex in the past. During the 1990s,
Wessex has successfully managed a $2.0 billion investment program on time and
below the price allowed by regulation. Current regulatory reports show Wessex as
having among the lowest unit costs and achieving the second highest return on
capital of the water and wastewater companies in the United Kingdom.
    
 
     We will apply Wessex's operational and capital expenditure management
skills in our global water business. We believe many of these skills are
transferable to other water and wastewater assets or services we will acquire or
manage.

  REGULATORY AND GOVERNMENT AFFAIRS EXPERTISE
 
     Our management team has extensive experience in working with regulators and
other governmental agencies. For example, our executives include:
 
     - The executive and regulatory team from Wessex, which has operated for 10
       years in the U.K.'s privatized water sector
 
     - The former general manager of the Metropolitan Water District of Southern
       California, which through its 27 member public agencies provides almost
       60% of the water used by nearly 16 million people living in portions of
       Los Angeles and southern California
 
     - A director of the Azurix regulatory team, who has 25 years of regulatory
       experience in electricity, gas and water, both in the United States and
       internationally
 
     - Executives and lawyers who have worked on private projects and
       distribution systems in the gas and electric sectors in Argentina,
       Brazil, China, Colombia, Croatia, Germany, India, Italy, Malaysia, the
       Philippines, Poland, the United Kingdom and the United States, among
       other countries
 
These members of our management team have extensive government affairs
experience and have often been involved in building relationships with local and
national governments and advising these governments on how to structure their
privatization process and regulatory regime to encourage foreign investment. In
some cases, they have direct experience in the countries and even the regions or
municipalities where we will pursue projects and operate assets, sometimes
working with the same governmental officials who may make decisions regarding
water and wastewater privatizations.
 
     As governments around the world turn to the private sector to fill their
water needs, they will draw on examples of successful privatizations in the
water sector elsewhere and, if applicable, in gas and electric sectors in their
own country. For example, the United Kingdom's privatizations of its electric
and gas sectors already has served as a model for many countries' privatizations
of those sectors, specifically, Argentina, Brazil, Chile and Colombia. We
believe governments will look to the U.K. model in water as well, and through
Wessex we are very familiar with that regime. For example, the recent water
privatization in Chile follows a national regulatory regime like the United
Kingdom, which adheres to the principles of incentive-based regulations.
Although the methods of calculating rates of return are slightly different, the
core principles remain the same. As another example, highly successful
build-own-transfer projects and privatizations of gas and electric distribution
networks have occurred in Argentina, Brazil, China, Colombia, Germany, Eastern
Europe, India and the Philippines. As those countries look for precedents in
water and wastewater, they will turn to many of the projects and systems on
which our executives previously have worked.
 
   
     Although we believe that the regulatory and government affairs expertise
demonstrated by our management team in electricity and gas is transferable to
water and wastewater privatizations, there are some differences between the
sectors. Because water is an essential good affected by health, safety and
environmental issues, regulation of water is more influenced by socioeconomic
and welfare pressures than electricity and gas regulation. In addition, water
and wastewater utilities are typically vertically integrated natural monopolies,
often owned by a public entity, and subject to greater regulation than electric
and gas utilities which are more often privately held and subject to greater
competition. Finally, water and wastewater businesses are more often regulated
at a local or regional level, as compared to national regulation, than
electricity and gas.
    
 
     Despite these differences, we believe that the experience of our management
team in the fundamental aspects of regulation and privatization is transferable
to water and wastewater privatizations.
 
  FINANCING EXPERTISE
 
     Access to capital is essential in the global water business due to its
significant financial requirements. We plan to employ sophisticated financing
techniques and instruments similar to those successfully used by members of our
management team in other infrastructure-intensive businesses. Our executives
have
                                       57
<PAGE>   63
 
   
experience in raising large amounts of capital through the capital markets and
through innovative financing structures. In addition, the team brings experience
in attracting private equity capital and using this capital to enhance the
borrowing capacity of our projects and to achieve greater returns for equity
holders. In financing a project through debt, we may enhance returns by placing
a portion of the debt at the level of the holding company created to own a
particular concession or facility. As our portfolio grows and matures, we also
intend to enhance our equity returns and reduce overall risk exposure through
opportunistic sales of all or a portion of individual assets or investments. In
addition, our management has experience in applying financing techniques
familiar to the domestic infrastructure market, such as leveraged leases, to
international markets.
    
 
   
     Many of our executives have developed extensive contacts and experience in
the global financial market. We intend to work together 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 intend to consider acquisitions of privately owned water and
wastewater assets throughout the world with predictable contractual or regulated
revenue streams that will complement our portfolio and strengthen our
competitive position in the global water industry.
    
 
   
     We intend to acquire water and wastewater assets through participation in
public tenders and privately negotiated transactions throughout the world,
including Europe, North America, Latin America, the Caribbean, the Middle East,
Africa, Asia and the Pacific Rim. As the trend toward privatization continues,
we expect new opportunities to materialize around the world. See "-- The Global
Water Industry -- Trend Toward Government Outsourcing Through Private Sector
Privatization."
    
 
     We intend to target opportunities where there is potential for increased
returns and where we can draw on the experience of our management team in
regulatory and rate case analysis, political risk assessment, country-specific
project development and water infrastructure operation. In some instances, we
may join with other parties, including local entities, in acquiring or bidding
on assets. We will evaluate potential projects and acquisitions based on a
variety of financial, strategic, regulatory and operational factors and utilize
our sophisticated financial, legal and tax analysis capabilities to determine
the appropriate acquisition and ownership structure designed to minimize risks.
From inception, the analysis of potential acquisitions will be staffed by our
employees with assistance from affiliated companies and
 
                                       58
<PAGE>   64
 
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.
 
   
     Each of Azurix Europe and Wessex is a party to various credit facilities
and loan agreements with restrictive covenants. We do not believe that these
existing credit facilities will impair our ability to carry out our business
strategy. Although the senior credit facility places restrictions on Azurix
Europe's ability to engage in mergers, acquisitions or asset sales, it does not
place any such restrictions on Azurix. This senior credit facility specifically
permits Azurix Europe to lend funds to other subsidiaries or affiliates of
Azurix for the purpose of making investments in, or acquisitions of, water or
wastewater related assets or businesses around the world. In addition, the other
existing credit facilities and loan agreements do not prohibit Azurix from
engaging in mergers, acquisitions or asset sales. In addition, these agreements
do not hinder Azurix's ability to incur indebtedness at the Azurix level or
incur project specific indebtedness with the borrowing capacity generated from
the cash flows of future acquisitions. See "Description of
Indebtedness -- Indebtedness of Azurix Europe."
    
 
   
     Enron and Azurix have entered into a business opportunities agreement that
limits the businesses that we may pursue. The agreement allows us, only with
Enron's consent, to engage in businesses outside the water and wastewater
industries, or in which water and wastewater is not expected to generate the
major component of value. This agreement thus limits our ability to pursue
potentially profitable ventures that are not clearly in the water and wastewater
sector, even though those opportunities come to our attention on account of our
activities in water and wastewater. See "Transactions with Enron, Atlantic Water
Trust and Marlin Water Trust -- Agreement Regarding Business Opportunities and
Related Matters."
    
 
     OWNING, OPERATING AND MANAGING WATER AND WASTEWATER ASSETS. To ensure a
smooth transition and to introduce more efficient working practices in the
concessions and businesses we acquire and the start-up of new facilities we
construct, we will send specialist transition teams of experienced staff with a
full range of skills. Existing employees of Wessex, including over 300
engineers, scientists and other specialists, will be made available to operate
our assets, especially during critical periods of takeover or start-up. We
intend to use the systems and working methods that Wessex successfully employed
to increase productivity and reduce costs.
 
     Following an acquisition of a water or wastewater asset, we intend to:
 
     - Enhance income by extending services and increasing operating revenues
 
     - Reduce operating costs and capital expenditures through better management
       and procurement strategy
 
     - Increase efficiency through the use of technology and management
       information systems
 
     - Apply innovative financing techniques and sound financial and risk
       management techniques
 
     Revenue Enhancements. Water and wastewater systems offer many opportunities
to increase operating revenues. For example, we might expand the number of
customers connected, while more efficiently managing the capital expenditures
required to serve them. New customers could result from inherent population
growth or migration to urban areas in the service territory. Another operating
revenue enhancement is the effective use of water meters. Many water systems
around the world do not use water
 
                                       59
<PAGE>   65
 
meters. By installing meters where appropriate, we could track water demand more
effectively and allocate water resources and service teams more efficiently.
Where permitted, we will shorten billing periods, which expedites receipt of
operating revenues and increases their collectibility. We will also apply more
sophisticated billing technology to assure that customers are being billed and
delinquent accounts are being pursued. Through improved service and better
community relations, we expect to reduce uncollectibles.
 
     Cost Containment Strategies. Our experience at Wessex helps us identify
ways to control expenditures in operating our water and wastewater systems and
facilities worldwide. These techniques are highly transferable from one location
to another. In particular, we intend to:
 
     - Use sophisticated tracking and monitoring equipment to reduce water
       losses from leakage and theft
 
     - Reorganize the workforce to improve productivity
 
     - Procure equipment, chemicals and ancillary services more cost effectively
 
     - Shorten construction periods
 
     We expect that these value-added strategies will allow us to realize
attractive returns on our global water industry investments. Whether responding
to a tender or negotiating a contract directly, we expect to combine our
experience from the concessions and projects we already have with our financing
skills to offer a highly competitive price and, once we acquire an asset, to
serve our customers efficiently and effectively.
 
  PROVIDING MUNICIPAL AND INDUSTRIAL SERVICES
 
     We intend to provide a broad range of cost-effective services to owners of
water and wastewater systems in governmental, commercial, industrial and
agricultural markets around the world through innovative technological,
environmental and financial solutions.
 
     Our water related services business will target municipal and industrial
customers, initially in the United States and Europe, that are seeking to
outsource the management of their systems. These customers generally desire a
service provider with the operating experience and capital to provide reliable
water supply and wastewater treatment services and the ability to comply with
more stringent regulatory requirements for water quality and environmental
protection. The current market has few operators that manage a large number of
diverse assets and thus have the skills to compete effectively. By consolidating
contracts for operation and management of treatment facilities and management of
biosolids disposal or reuse through acquisition and growth, we can achieve
economies of scale and operational efficiencies in this business that will allow
us to compete more effectively.
 
     Furthermore, by offering operations, management and engineering, residuals
management and underground infrastructure remediation and development services,
we believe that we will position ourselves to capitalize on privatizations as
they occur. Providing a full range of services represents our primary method for
consolidating municipal outsourcing activities, promotes access to a full range
of governmental clients and allows municipalities to explore all their options
from outsourcing services to full privatization of their systems. Working with
municipal clients will also allow us to understand local markets and identify
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 build-own-transfer projects for long-distance
pipelines, aqueducts and reservoirs in the Middle East and other projects to
extract water in Latin America.

  WESSEX
 
   
     Wessex's principal business is providing water supply and wastewater
services in southwestern England through Wessex Water Services Ltd., a wholly
owned subsidiary. In December 1998, the Office of Water Services, the industry
regulator for England and Wales commonly called Ofwat, published its assessment
of relative operating efficiency, which showed Wessex as the most efficiently
operated water and wastewater company under its supervision. Ofwat also has
recognized Wessex for providing among the highest overall standards of service
of water and wastewater companies in the industry. Independent research shows
that over 90% of Wessex's customers consistently rate its service as "excellent"
or "good." During the 1990s, Wessex has successfully managed a $2 billion
investment program on time and below the price allowed by regulation. Wessex's
other principal subsidiary is SC Technology, which conducts business as Swiss
Combi and designs, sells and operates biosolid drying plants.
    
 
     Much of Wessex's success in delivering high standards efficiently is due to
the investment in and application of the latest technology. Sophisticated
control and planning systems have largely eliminated the need for Wessex's 2,500
installations to be permanently manned. Instead, water supply and wastewater
treatment collection and distribution systems can all be monitored from one
central base. Regular maintenance and response to customer requests or
emergencies are handled through an integrated planning and management system
that ensures rapid response in the most efficient manner.
 
     WESSEX WATER SERVICES. Through Wessex Water Services, Wessex provides water
supply and wastewater services in southwestern England. Wessex has a virtual
monopoly over water supply and wastewater services in its region, with the
exception of the cities of Bristol and Bournemouth and a small area of rural
Wiltshire, where three companies provide only water and Wessex provides
wastewater services.
 
                                       61
<PAGE>   67
 
   
     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
102,000, and the largest town for which Wessex provides wastewater services is
Bristol, with a population of approximately 400,000 (approximately 800,000
including the surrounding area). The region's economy, which is one of the
fastest growing in the United Kingdom, is based on agriculture, financial
services, aerospace, defense establishments and specialist manufacturing.
    
 
   
     Water Supply Services. Wessex supplies approximately 400 million liters of
water per day to a population of approximately 1.1 million using its water
infrastructure. The system includes approximately 138 water sources, 128 water
treatment plants, 320 pumping stations, 360 storage reservoirs and 11,000
kilometers of water mains. Wessex serves approximately 510,000 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. Wessex has reduced
leakage in terms of volume by 20% since 1993. 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.
 
   
     By the end of 1999, Wessex will have invested approximately $700 million in
capital projects related to improvements in its water infrastructure since
privatization in 1989, of which over $400 million will have 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 U.K. 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 350 wastewater treatment plants, 1,300 pumping
stations and 15,000 kilometers of sewers. Residential customers account for
approximately 76% of wastewater revenues and commercial customers account for
24%.
    
 
     Wastewater is collected in the wastewater system and pumped or gravitated
to wastewater treatment plants where the wastewater passes through processes
designed to remove biosolids and purify the wastewater. Following further
processes, Wessex disposes of 83% of its biosolids to agricultural land, uses
12% in landscaping and land reclamation work and disposes of 5% in landfills.
Approximately 20% of biosolids are subjected to an advanced heated drying
treatment at Wessex's major wastewater treatment facility at Avonmouth, near
Bristol. Wessex is currently installing similar drying facilities, referred to
as
 
                                       62

biodriers, at Bournemouth and Weston-super-Mare. A second plant is also planned
for construction in 1999 at Avonmouth.
 
   
     By the end of 1999, Wessex will have invested approximately $1.3 billion in
capital projects related to improvements in its wastewater infrastructure since
privatization, of which approximately $800 million will have been invested since
1993. Wessex has been upgrading many of its wastewater treatment plants to
comply with European Union legislation. At some of its treatment facilities,
Wessex has introduced advanced filtering technology using membranes, ultraviolet
disinfection and fully enclosed underground plants in connection with the
treatment of wastewater. Wessex's new wastewater treatment plant at Porlock is
the largest operational plant in Europe to use membrane filtering technology to
process wastewater to a state that 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
350 wastewater treatment plants. The following is a list of the five largest
water treatment plants operated by Wessex:

     Customer Charges. The Director 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" and "Regulatory
Matters -- U.K. Regulatory Matters."
    
 
     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.
 
                                       63
<PAGE>   69
 
     Charges are generally set on a standard tariff basis. Charges for bulk
supplies of water are usually determined on an individual basis, as are charges
for some larger commercial water supplies and some industrial wastewater. The
charging basis for bulk supplies in some cases provides for annual recalculation
by reference to the expenditure associated with the supply. Wastewater from
industrial users is normally charged on a formula basis taking account of the
volume of wastewater, its strength and costs of removal and treatment.
 
     In November 1998, following public consultation in April, the U.K.
Government announced new legislation to regulate water charging in England and
Wales. The proposed legislation is currently before the U.K. Parliament and
would grant domestic customers the right:
 
     - To resist water metering in their current homes where they are not using
       water for non-essential purposes
 
     - To have a free meter installed if they wish to have one, where this is
       practicable
 
     - Where they have taken up the right to have a free meter installed, to
       revert to an unmetered basis of charging within 12 months if they so
       choose
 
   
Prior to this legislation, Wessex already had implemented a free metering
program with a right to revert. In addition, the proposed legislation would
enable the U.K. Government to:
    
 
   
     - Protect vulnerable customers with high essential water use, who live in
       homes with meters, from higher than average water bills
    
 
   
     - Prevent water companies from disconnecting domestic customers for
       non-payment
    
 
   
     - Require companies to cease using rateable property values as a basis for
       unmeasured charging
    
 
   
     - Grant new powers for the Director to approve charging schemes, taking
       account of guidance from the Secretary of State
    
 
   
     A review of the customer charges of Wessex is in process and new price
limits will apply from April 1, 2000. See "Risk Factors -- Water and wastewater
companies face price and other regulation that could reduce our operating
revenues," "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Outlook" and "Regulatory Matters -- U.K. Regulatory
Matters."
    
 
   
     SC TECHNOLOGY. In 1996, Wessex acquired SC Technology, which does business
under the name of Swiss Combi. Based in Switzerland, SC Technology is one of the
leading biosolid drying companies in the world. SC Technology designs, sells and
operates environmentally sound biosolid drying processes and markets recycled
biosolids for agriculture and land reclamation. SC Technology currently has
approximately 40 plants completed or under construction, located in more than
ten countries, primarily in Western Europe.
    
 
   
     Volumes of biosolids are increasing worldwide. Historically, these
biosolids were supplied to farmers or disposed of at sea. Wessex believes that
the ban imposed on disposal of biosolids at sea, together with concerns from
food retailers about the recycling of untreated biosolids over agricultural land
and air pollution problems resulting from the incineration of biosolids, make
the biosolid drying process an attractive method of biosolid disposal for the
future. The Swiss Combi process uses a contained drying system to produce
pasteurized dried granules that 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 or 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,
 
                                       64
<PAGE>   70
 
Argentina. Enron has contributed to Azurix its 32.1% interest in Obras
Sanitarias Mendoza, the concession holder. SAUR also owns a 32.1% interest in
the concession holder, local private investors own a 3.3% interest, Italgas owns
a 2.5% interest, employees own a 10.0% interest and the Province of Mendoza owns
the remaining 20.0%. Obras Sanitarias Mendoza is currently operated by SAUR
under an operations agreement and is governed by a five-member board of
directors, two of which have been appointed by Azurix.
 
   
     The concession is located in the desert bordering Chile at the base of the
Andes mountains. Its service territory covers six municipalities. The Mendoza
area has a strong economy and is one of Argentina's fastest growing provinces.
Per capita revenue is among the highest in Argentina due to the petroleum and
mining industry activity in the area, and per capita water usage is among the
highest in the hemisphere.
    
 
   
     The concession holder is charged with operating, maintaining and upgrading
its 10 drinking water plants and 17 wastewater treatment plants as well as
associated distribution and collection networks to Mendoza. Obras Sanitarias
Mendoza serves over one million water customers and has 285,000 water
connections. Obras Sanitarias Mendoza provides wastewater services to 883,000
people and has 210,000 wastewater connections. The concession contract requires
Obras Sanitarias Mendoza to expand the water and wastewater connections in the
concession area over the next 10 to 15 years. Through 2015, approximately $180
million is expected to be spent on new connections, new water and wastewater
treatment facilities and system improvements. Obras Sanitarias Mendoza's assets
include raw water transportation pipelines and aqueducts, drinking water
treatment plants and other general assets.
    
 
   
     Neither SAUR nor Azurix has any obligation to contribute further capital to
Obras Sanitarias Mendoza. However, in May 1999, each of SAUR and Azurix agreed
to loan $2.25 million to Obras Sanitarias Mendoza to fund working capital. The
loan to be made by Azurix bears interest at a rate of 6.98% per annum and
matures on July 20, 1999.
    
 
     Water supply comes primarily from the regional river, Rio Mendoza. The
surface water feeds by gravity to treatment plants. The remaining groundwater
comes from approximately 160 wells. Obras Sanitarias Mendoza uses four large
lagoon systems to provide the majority of wastewater treatment within the
concession area. Average billing is approximately $30 bi-monthly for water and
wastewater.
 
   
     Obras Sanitarias Mendoza is required to meet standards of service
established by the special purpose regulatory body known as Ente Provincial de
Agua y Saneamiento and to make appropriate arrangements for the improvement and
extension of service. The standards of service include quality and availability
requirements and were initially set by the concession contract. Each year, the
operator must submit an annual report that will specify, among other things,
Obras Sanitarias Mendoza's progress with respect to its plan of operation and
expansion.
    
 
     Obras Sanitarias Mendoza must pay the Province a yearly royalty based on
net operating revenues collected. This royalty is equal to 3.85% of net
operating revenues collected in the first five years of the concession and 9.98%
thereafter.
 
     The concession may be terminated for fault of the concession holder under
any of the following circumstances:
 
     - Repeated failure to provide service as required by the concession
       contract
 
     - Repeated violation of applicable environmental regulations
 
     - Unjustified delays in completion of the then-current plan of operation
       and expansion
 
     - Willful withholding of information from the environmental regulator
 
     - Failure to maintain adequate performance bonds
 
     - Any change in the corporate structure of the concession holder or the
       operator without the prior approval of the Province
                                       65
<PAGE>   71
 
     The Province can undertake the partial or complete termination of the
concession for noncompliance with the terms of this contract or for public
interest reasons. In the event of a termination for public interest reasons, the
Province must compensate the concession holder for its lost investment. Obras
Sanitarias Mendoza believes it is in compliance with the concession contract in
all material respects. As the concession holder, Obras Sanitarias Mendoza would
be liable for any claims or damages, environmental or otherwise, relating to
this concession. As a shareholder, we believe that our potential liability is
limited to our investment in the concession holder.
 
  CANCUN, MEXICO
 
   
     On March 24, 1999, we acquired for $13.5 million a 49.9% economic interest
in and the right to manage and operate the water and wastewater treatment
concession for Cancun and Isla Mujeres, Mexico. Desarrollos Hidraulicos de
Cancun, S.A. de C.V. is the concessionaire that holds the concession. Affiliates
of one of the former shareholders, Grupo Mexicano de Desarrollo, S.A., own an
aggregate 50.1% economic interest in the concessionaire. On February 25, 1999,
we lent the concessionaire $15 million to permit it to retire a portion of its
indebtedness, and we may make additional loans of up to $10 million to initiate
improvements in the wastewater treatment system.
    
 
     The concession was initially granted on the condition that the
concessionaire would invest capital in projects to provide services under the
concession. As a result of the devaluation of the Mexican peso in 1994, the
concessionaire was unable to meet some of its investment obligations and the
government of the State of Quintana Roo in August 1996 designated the state
regulatory authority, known as CAPA, to operate the concession. In February
1997, Grupo Mexicano and the concessionaire agreed with the state government
that, as a condition to reassuming operation of and retaining the concession,
the concessionaire would make the necessary investments and form an association
with an experienced operator of water concessions. In general, the parties
involved agreed on the following:
 
     - The concessionaire would be responsible for adjusting its financial
       statements and making pertinent payments in order to show financial
       stability and sustainability
 
     - The concessionaire and CAPA would review the capital expenditure program
       for the period 1997-2000 and would implement it immediately after
       approval
 
     - The parties would reconstruct the concession agreement and develop a new
       one with the National Water Commission (Comision Nacional de Agua) acting
       as a mediator
 
     The cost to the concessionaire for these investments is estimated at $44
million over the next five years. The concessionaire is required to pay to the
State of Quintana Roo an annual concession fee of 7.5 million pesos (in 1993
pesos), adjusted annually in accordance with changes in the Mexican consumer
price index. The concession extends to October 2023.
 
     At the end of the concession term, and any extensions, the concessionaire
will be required to deliver to the government at no cost the facilities and
equipment used to provide services under the concession. The concession may be
revoked by the government in the event of a breach of the concession terms if
the concessionaire does not present a program to cure the breach within 30 days
of notice of default. The concession can be terminated if the concessionaire is
bankrupt, insolvent, liquidated or dissolved. The concession may also be revoked
upon the transfer of part or all of the concessionaire's rights under the
concession without government approval or if the concessionaire does not
maintain a performance bond in an amount equal to 10% of annual operating
revenues for the prior year.
 
     Based on figures available at the date of acquisition, the concessionaire
serves a population of approximately 390,000 through 73,000 connections. An
estimated 65% of the concession's operating revenues are derived from the supply
of drinking water to tourist hotels, whose operating revenues are primarily U.S.
dollar based.
 
                                       66
<PAGE>   72
 
   
     The operations and tariffs for water and wastewater systems in the State of
Quintana Roo are regulated by CAPA. The water tariff paid by the hotels and
commercial and industrial customers is adjusted monthly according to the change
in Mexico's consumer price index as published by the Mexican government. In
addition, the concession provides that the rate paid by the hotels will be
increased in the event of a variation of the Mexican peso/U.S. dollar exchange
rate in excess of 15% due to a short-term event. The remainder of operating
revenues come from residential and public services drinking water supply and
from wastewater services. Residential drinking water rates are adjusted annually
with changes in the Mexican minimum wage established by the minimum wage
commission. Currently, less than 40% of the wastewater in the Cancun urban zone
that is collected is being treated.
    
 
     The tariff rates, which vary according to the customer class, resulted in
an average billed consumption of 7.95 pesos per cubic meter of water consumed in
1998. Operating revenues and expenses of the concessionaire in 1998 were 205
million pesos ($22.0 million) and 164 million pesos ($17.7 million),
respectively. Operating income in 1998 was 40 million pesos ($4.4 million).
These figures are estimated by management and have not been audited. The U.S.
dollar amounts have been translated based on the April 30, 1999 exchange rate of
9.3 pesos to one U.S. dollar.
 
     We have three seats on the board of directors of the concessionaire, while
the 50.1% shareholders have two. We have the right to appoint the chief
executive officer, the chief financial officer and the chief operating officer
of the concessionaire. The 50.1% shareholders have the right to appoint the
chairman of the concessionaire's board and the non-voting board secretary.
Resolutions concerning major corporate actions and governance issues require
supermajority approval.
 
     As the concessionaire, Desarrollos Hidraulicos would be liable for any
claims or damages, environmental or otherwise, relating to this concession. We
believe that our potential liability is limited to our investment in the
concessionaire.
 
  PHILIP UTILITIES MANAGEMENT CORPORATION
 
   
     On May 18, 1999, we purchased all of the stock of Philip Utilities
Management Corporation, a water and wastewater services company headquartered in
Hamilton, Ontario, Canada. We paid an adjusted purchase price of $106.3 million
in cash, approximately 68% to Philip Services Corporation and approximately 32%
to Ontario Teachers' Pension Plan Board. Under the share purchase agreement,
Philip Services and Ontario Teachers have indemnified Azurix for the breach of
any of the sellers' or Philip Utilities' representations, warranties or
covenants made in respect of the purchase. These indemnities are limited to
claims in excess of $50,000, after the first $1,000,000 of such claims has been
absorbed by Azurix, up to an aggregate limit of $10,000,000. In addition, the
sellers prorated indemnification obligations with respect to breaches by Philip
Utilities based upon their respective share ownership of Philip Utilities.
    
 
   
     Philip Utilities operates facilities in three of the ten provinces of
Canada, with a concentration of operations in Ontario, and in the United States
in the states of Arizona, Florida, Georgia, Louisiana, Maine, New Jersey, Texas
and Washington. In calendar year 1998, Philip Utilities had operating revenues
of approximately $100 million. The following is a discussion of Philip
Utilities' business operations.
    
 
   
     OPERATIONS, MANAGEMENT AND ENGINEERING. Philip Utilities' operations,
management and engineering business is divided along two business lines,
including contract operations and engineering and automation.
    
 
     Contract Operations. Philip Utilities' contract operations division
contributes approximately 30% of its operating revenues. Philip Utilities'
largest contract operation projects are in Hamilton-Wentworth, Ontario and
Seattle, Washington. In 1994, Philip Utilities won the contract to operate and
maintain the 192 million-gallon-per-day water treatment facility and the 110
million-gallon-per-day wastewater treatment facility of the regional
municipality of Hamilton-Wentworth. Under the operations agreement, Philip
Utilities receives an adjustable flat fee plus a portion of any cost savings
realized under the contract. Services provided under the operations agreement
include the day-to-day operation, maintenance, repair, and permitting and
compliance of the facility.
 
                                       67
<PAGE>   73
 
   
     Under the terms of the plant operations agreement between
Hamilton-Wentworth and Philip Utilities, Hamilton-Wentworth pays an annual fee
to Philip Utilities equal to an agreed upon base budget and adjusted for
inflation, salary and wage increases, insurance costs, ash, sludge and grit
disposal costs and increases in Philip Utilities' cost of corporate overhead. In
addition, Hamilton-Wentworth shares in approximately 40% of actual annual costs
savings over the base budget amount by reducing the annual fee due to Philip
Utilities. Under the first four years of the plant operations agreement,
Hamilton-Wentworth paid annual fees to Philip Utilities CN$15.4 million in 1995,
CN$15.6 million in 1996, CN$16.0 in 1997 and CN$15.8 million in 1998.
    
 
   
     Philip Utilities' second largest contract operation project is the design,
build and operate contract for the 120 million-gallon-per-day Tolt River
Treatment Facility that is currently under construction in Seattle, Washington.
In 1996, Philip Utilities teamed with the engineering firm of Camp Dresser &
McKee, Inc. to win this 15-year contract, which is renewable by the City of
Seattle for two additional periods of five years each. CDM Philip, Inc., an
80%-owned subsidiary of Philip Utilities, receives approximately $74.8 million
in design and construction fees. CDM Philip subcontracted the design/build
portion of the contract to Dillingham Construction, N.A., Inc. for approximately
$63 million. Construction of the Tolt River plant is currently on schedule, with
the facility scheduled to commence operations in December 2000. Once operations
have commenced, CDM Philip is entitled to an annual service fee of approximately
$1.7 million, subject to modification for incentive bonuses, pass-through costs
and other adjustments.
    
 
     Engineering and Automation. Philip Utilities' engineering and automation
activities are based in Ontario and Atlanta, Georgia. Philip Utilities provides
plant design, construction, project management, and process design and
engineering services primarily for municipal customers and other Philip
Utilities operations. Philip Utilities also provides process automation and
instrumentation services including design, assembly, testing and installation of
supervisory control and data acquisition systems and other computer control
technologies primarily for municipal customers. Philip Utilities' engineering
and automation activities contributed approximately 12% of its operating
revenues in 1998.
 
     RESIDUALS MANAGEMENT. Residuals management accounted for approximately 16%
of Philip Utilities' operating revenues in 1998. Philip Utilities' residuals
management division is comprised of three complementary operations that apply
dewatering and land application methods to residuals management:
 
   
     - Trimax Residuals Management, Inc. primarily serves the municipal water
       and wastewater sector, with the majority of its operating revenues
       derived from dredging and removing water from sewage lagoons and tanks.
       Trimax is headquartered in Edmonton, Alberta and conducts operations in
       the United States and Canada. Major contracts are held with the Greater
       Vancouver Regional District and the cities of San Diego and Detroit, as
       well as several pulp and paper companies. Trimax has built its business
       around a mobile water removal technology that provides a great deal of
       flexibility and versatility in the marketplace. The product of this
       process is a manageable biosolid that is typically disposed of through
       land application. Trimax accounted for approximately 63% of Philip
       Utilities' residuals management operating revenues in 1998.
    
 
   
     - Braemar Acres Limited processes industrial wastewater and municipal
       biosolids for disposal through land application. Braemar Acres,
       headquartered in Ontario, has existing operations that are principally
       located within the province of Ontario and include disposal of lime
       sludge for a sugar manufacturer, processing of paper sludge for five of
       the six pulp and paper companies in eastern Ontario, waste food organics
       recycling, and biosolids for the Hamilton-Wentworth facilities and the
       city of Niagara, Ontario. Braemar Acres accounted for approximately 10%
       of Philip Utilities' residuals management operating revenues in 1998.
    
 
     - Enviroganics of Texas, Inc. is a Houston-based company that provides
       wastewater biosolids management and residuals management services to over
       165 wastewater treatment facilities in Texas. Enviroganics' services
       include removal and processing of biosolids, on-site mobile water
       removal, operation of customer's processing equipment and hauling and
       disposal through land
 
                                       68
<PAGE>   74
 
      application of biosolids. Services are typically rendered under purchase
      orders instead of long-term contracts. Enviroganics accounted for
      approximately 25% of Philip Utilities' residuals management operating
      revenues in 1998.
 
   
     UNDERGROUND INFRASTRUCTURE REMEDIATION AND DEVELOPMENT. Philip Utilities
offers a wide range of underground asset management services to customers in the
United States and Canada. These services include closed circuit television
inspection and location mapping, as well as pipeline repair and rehabilitation.
Since 1996, Philip Utilities has focused on migrating from traditional pipe
rehabilitation to trenchless technologies. Philip Utilities employs a variety of
trenchless technologies for which it holds licenses in various geographic
territories. Among these licensed products are epoxy resins, polyurethane
fold-and-form pipe, a roll-down pipe product, two cured-in-place products and a
spot repair system. The underground infrastructure division contributed
approximately 40% of Philip Utilities' operating revenues in 1998.
    
 
     OWNERSHIP OF WATER AND WASTEWATER ASSETS. In addition to its outsourcing
operations, Philip Utilities owns two utilities that serve approximately 3,000
end use customers in suburban areas around Houston, Texas: Southwest Utilities,
Inc. and Walker Water Works, Inc. These two utilities own and operate both water
and wastewater treatment services and are regulated by the Texas Natural
Resource Conservation Commission and the Environmental Protection Agency. This
is Philip Utilities' smallest division and contributed approximately 2% of its
operating revenues in 1998.
 
   
PENDING ACQUISITION
    
 
   
     On May 14, 1999, we submitted bids for two of the three regions of the
water and wastewater system operated by Administracion General de Obras
Sanitarias Buenos Aires in the Province of Buenos Aires, Argentina. On May 18,
1999, the provincial government notified us that we were the prevailing bidder
on both of the regions for which we bid at a price of $438.6 million. Assuming
final confirmation by the province, the schedule calls for us to assume
operation of these systems on June 18, 1999.
    
 
   
     Azurix initially will own 90% of the concessionaire, with employees owning
10%. A consortium of local electric cooperatives has agreed to acquire a 1.2%
interest for $5 million, with an option to increase its interest to up to 10%
within approximately six months following our assumption of operations.
    
 
   
     The Province of Buenos Aires surrounds the Argentine capital city. It is
the country's largest province, with a total population of approximately 13.5
million. The provincial water and wastewater administration currently serves a
population of approximately 3.8 million, with municipalities serving the
remainder of the population having water or wastewater service. The two regions
we are to acquire have a total population of approximately 2.0 million and
approximately 450,000 water or wastewater customers. They include the provincial
capital of La Plata and the large industrial city of Bahia Blanca. We expect to
be able to expand operations to surrounding municipalities and to offer
industrial customers cost-effective alternatives.
    
 
   
     These concessions last for 30 years and require the concessionaire to
complete a specified investment plan that we estimate will cost approximately $1
billion. The concessionaire must commit to increase water and wastewater
coverage over a 10-year period in percentages varying from region to region. It
also must increase metering, which is at low levels or nonexistent in some of
these regions. The concession agreement provides penalties for failure to
achieve the investment plan on time, although relief is available if the delay
is due to complications in obtaining work licenses through local municipalities.
    
 
   
     The concessionaire is responsible for complying with all environmental and
water quality standards, with a grace period at the beginning of the concession
term. Serious or repeated violations of the concession contract, the regulatory
law or the supervisory agency's decisions could permit the provincial government
to terminate the concession. The concessionaire may use existing assets, which
remain the property of the province, but will own improvements made to the
system. We expect that approximately 1,200 employees of the provincial system
will be transferred to the concessionaire for these regions.
    
 
                                       69
<PAGE>   75
 
   
     The Organismo Regulador Bonarense de Aguas y Saneamiento, a newly formed
unit of the provincial Ministry of Public Works, will regulate the collection,
purification, transportation and distribution of potable water and the
collection, treatment, disposal and marketing of wastewater, including
industrial effluents. The agency's jurisdiction also includes setting tariffs
and regulating the extraction and use of common water sources.
    
 
   
     Initially, the tariff will remain the same as was in effect prior to
privatization. The first tariff review is expected around the third year
following the privatization. The tariff then is to be reviewed every five years
in light of the five-year program of investment. The concessionaire or the
regulator may ask for an increase or reduction if consumer cost indices change
by more than 3% or if there are material changes in Argentine tax law, other
than value added tax or income tax, changes in water quality standards or
environmental regulations or substantial changes in the condition of the
concession. Both the concession contract and the governing law provide that
tariff modifications may not be used to penalize the concessionaire if it
operates more efficiently than expected. The concessionaire is required to
provide lower rates to specified users, including retired persons with low
income, care centers for the elderly and for physically challenged children,
public schools, public sports facilities and libraries.
    
 
   
UPCOMING PRIVATIZATION BIDS
    
 
   
     We are currently pursuing two large upcoming privatizations, which are
expected to be awarded in the second quarter of 1999. There can be no assurance
that we will win these bids or that the timing, size and terms of these bids
will not change.
    
 
   
  BERLIN, GERMANY
    
 
   
     The government of the German State of Berlin, which includes the capital
plus some surrounding suburbs, received bids in March 1999 for a 49.9% interest
in its water and wastewater system. The Berlin system is the largest system
currently being privatized in the world, serving a population of approximately
3.4 million and having gross revenues of $1.04 billion and net revenues of $35
million in 1998, according to the audited financial statements that the
government has provided. The government originally announced that it hoped to
receive a minimum of 2.0 billion German deutsche marks ($1.1 billion) for this
49.9% interest.
    
 
   
     The Berlin company has established a series of subsidiaries in recent
years. The main subsidiaries include a waste-to-energy facility that gasifies a
wide range of residual and waste materials, a local telecommunications operator
that operates a data network and targets users such as the media,
telecommunications companies, internet providers or power utilities and a
service company that plans, builds, operates and finances drinking water supply
systems and municipal and industrial wastewater treatment plants, as well as
wastewater systems.
    
 
   
     A consortium led by Azurix is one of the three consortia that the
government has selected with which to negotiate a possible sale. If successful,
Azurix would obtain an interest of 25.0% and a financial institution 24.9%, with
Azurix controlling the major decisions of the consortium. The government has
stated that it intends to make the award no later than June 1999, although there
is no assurance this sale will be awarded at such time or that the Azurix led
consortium will win the bid.
    
 
   
  SANTIAGO, CHILE
    
 
   
     Azurix has qualified to bid on the proposed sale of an interest in Empresa
Metropolitana de Obras Sanitarias, S.A., the state-owned water and wastewater
concession company for Chile's capital city of Santiago and adjoining suburbs.
Bids currently are due June 11, 1999, and are expected to exceed $400 million.
Through a shareholders agreement, the winner of the bid will have effective
control of the concession company. In order to achieve the objectives of the
privatization law, the government cannot own more than 50% of the concession
company's shares after the closing. It is expected that the winning bidder
ultimately will own 35% to 52%, depending on whether and to what extent the
government, existing
    
 
                                       70
<PAGE>   76
 
   
minority shareholders and other investors exercise rights to subscribe for new
shares during the first 14 months following closing.
    
 
   
     The Santiago company is the largest water and wastewater company in Chile,
representing approximately 35% of the total market in the country. Total
population in the concession area is approximately 5.1 million. Virtually all
households in the concession area have water service and approximately 97% have
wastewater collection service.
    
 
   
     The established regulatory system provides for a return based on a cost of
capital equal to the readjustable long-term instruments of Chile's Central Bank
plus a premium of 3.0% to 3.5%, but the total may never be less than 7%. The
tariff is revised every five years, but is calculated against a model company.
The concessionaire retains the benefits of more efficient operations. Publicly
available reports on the concession company show the company's operating margin
averaged 40% over the past five years with a collection rate of approximately
98%. However, only 3% of wastewater is treated, and environmental laws and the
mandated development plan will require investment in wastewater treatment.
Estimated capital expenditures of approximately $650 million will be needed
during the first five years after closing.
    
 
   
     Each bidder must notify the privatization agency by June 1, 1999 whether it
is participating in a consortium and, if so, the members of that consortium. We
are in discussions regarding a possible consortium in which we would have at
least a 50% interest, though a definitive arrangement has not yet been agreed.
The bidding rules permit a member of a consortium that has also qualified on its
own to bid on its own or as a member of a consortium, although that may not be
permitted under its consortium agreement depending on its terms.
    
 
SUPPLIERS
 
   
     We intend to achieve economies of scale in buying goods and services. In
addition, we expect to centralize purchasing arrangements to reduce costs and
improve quality. Wessex's only significant supplier of goods or services is
SEEBOARD plc, a subsidiary of CSW Corporation, which supplies electricity to
approximately 100 of Wessex's sites. Wessex pays approximately $6.4 million per
year, which represents approximately 5% of Wessex's annual operating costs. The
contract was effective October 1, 1997 and runs for two years. The price is
based upon a negotiated pence amount per kilowatt hour for each site. Wessex is
not dependent on any single supplier, including SEEBOARD, because its supplies
are readily available from alternative sources at market rates and on similar
terms. Except for SC Technology, which supplies biodriers to Wessex, and Enron,
which provides services under a services agreement with Azurix, none of Wessex's
suppliers is affiliated with it.
    
 
RESEARCH AND DEVELOPMENT
 
     Since our formation, we have established a link with the Water Research
Centre, which is conducting a U.K. industry-wide research and development
program that currently invests approximately $6.6 million each year in research
programs. The Water Research Centre is internationally renowned as the market
leader in water and wastewater technology. We will have a research department
based within the Water Research Centre at Swindon in the United Kingdom. The
Water Research Centre will also provide us with a service to monitor the
development of water and wastewater technologies across the world and with the
opportunity to access, and, when appropriate, invest in new technologies. Wessex
contributes approximately $160,000 per year to this program.
 
     Wessex carries out its own research and development to improve the
reliability and effectiveness of its treatment systems. In-house research and
development projects include development of a mobile filter for wastewater
treatment and disinfection and membrane filtering technology. Wessex has spent
approximately $1.6 million on these two project areas in the last three years. A
third major project area is pasteurization of wastewater biosolids using the
Swiss Combi heated drying technique. Wessex has spent approximately $640,000
over the last three years in this area.

EMPLOYEES
 
   
     As of May 21, 1999, we had approximately 165 employees, excluding employees
of Wessex. As of May 21, 1999, Wessex had approximately 1,440 employees, which
includes approximately 50 employees at SC Technology. As part of its efforts to
improve operating efficiencies, Wessex has reduced the number of its employees
by approximately 500 employees since March 31, 1993, primarily through attrition
and voluntary retirement packages.
    
 
INSURANCE
 
     We believe that our insurance arrangements, including self-insurance, are
customary for the industry and are adequate. Wessex, Mendoza and Cancun have
separate locally underwritten insurance policies covering employers liability,
public and products liability, excess public and products liability and their
motor fleets. Enron's corporate insurance program covers the direct exposures of
Azurix and the indirect exposures to Azurix from its less than wholly owned
subsidiaries, to the extent not covered by the subsidiaries' policies. Following
the offering, Azurix will continue to participate in Enron's corporate insurance
program. In the future, Azurix may establish a separate program for Azurix and
Azurix's subsidiaries.
 
LEGAL PROCEEDINGS
 
     There are no legal or arbitration proceedings, including any that are
pending or threatened, of which we are aware that if adversely determined would
have a material adverse effect on our financial position, liquidity or results
of operations.
 
                                       72
<PAGE>   78
 
                               REGULATORY MATTERS
 
   
     The following is a summary of regulatory matters relating to water and
wastewater operations in the United Kingdom, Argentina, Mexico, the United
States and Canada.
    
 
     In general, most countries where we have invested, or intend to consider
investments, have drinking water quality and environmental laws and regulations.
We intend to invest in companies or projects that operate in material compliance
with drinking water quality and environmental laws and regulations. However, we
cannot guarantee that the due diligence we perform in advance of investing in an
entity will identify any or all noncompliance with environmental laws and
regulations by such entities.
 
   
     Because the supply of clean drinking water and the treatment of wastewater
are essential societal needs, we anticipate that these activities will be
subject to at least some form of regulation wherever we do business. The nature
and extent of environmental laws and regulations vary from country to country,
and there may be wide disparities in the requirements from one part of the world
where we do business to another. Generally speaking, compliance with these laws
and regulations is mandatory and penalties, as well as injunctive and other
relief, are usually available in the event of noncompliance. Moreover, these
laws and regulations may require improvements to water and wastewater systems
that will require additional capital and operating costs for us to remain in
compliance.
    
 
     Changes in the nature of these laws and regulations, or in the level of
their enforcement, also have the potential to impact adversely our financial
results during the relevant period. These adverse impacts could cause our actual
financial results to differ materially from those we project, forecast, estimate
or budget. Moreover, changes in these laws and regulations may require
improvements in order to remain in compliance that can result in additional
capital and operating costs.
 
   
     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, there can be no assurance
that this approach will be adequate to address and manage all such risks
associated with our business.
    
 
   
     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,
Mexico, the United States and Canada.
    
 
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. The Water Industry Act 1991 imposes duties on the
Secretary of State and the Director as to how and when they should exercise
their functions under the Act. In particular, their primary duties are to
exercise their functions in the manner each considers best calculated to secure
that licensees properly carry out and are able to finance their functions,
including by securing reasonable returns on their capital. Subject to these
primary duties, the Secretary of State and the Director have other duties,
including
    
 
                                       73
<PAGE>   79
 
   
protecting customers' interests, promoting efficiency and economy by licensees
and facilitating competition. Therefore, in setting limits on the prices that
water and wastewater companies may charge, the Director is currently required to
allow 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 assumed by the Director in setting prices.
    
 
   
     Each water company is under a general duty to develop and maintain an
efficient and economical system of water supply within its license area and is
subject to duties of water supply. Each wastewater company is under a general
duty to provide, improve and extend a system of public sewers and to maintain
those sewers to ensure that its sewerage region is effectively drained. In
addition, discharges from wastewater treatment plants must be licensed by the
Environment Agency, and wastewater companies are responsible for regulating
discharges of industrial wastewater into sewers. Contamination caused by
wastewater discharged from a treatment plant may subject the wastewater company
to liability, including clean-up costs.
    
 
   
     Among his functions, the Director has powers to determine terms where
Wessex and the customer cannot agree. These include terms for, and requiring,
bulk supplies of water, the provisions of water for non-domestic purposes and
the connection of sewers and the reception, treatment and disposal of industrial
wastewater to public sewers. The Director is responsible for ensuring that water
and wastewater companies comply with their license conditions. Subject to a
power of veto by the Secretary of State for the Environment, conditions may be
modified by the Director with the consent of the licensee. Before making the
modifications, the Director must publish the proposed modifications as part of a
consultation process, giving third parties the opportunity to make
representations and objections that the Director must consider. In the absence
of consent, the only means by which the Director currently can secure a
modification is following a modification reference by him to the U.K.
Competition Commission. The Commission is required to investigate and report on
whether matters specified in the reference operate or may be expected to operate
against the public interest and, if so, whether the adverse public interest
effect of those matters could be remedied or prevented by modification of the
conditions of the license. If the Commission gives an adverse finding, it will
state in its report whether any adverse effects on the public interest could be
remedied or prevented by modification of the license. The Director must then
make such modifications as appear to him necessary for the purpose of preventing
the adverse effects specified in the report after giving due notice and
consideration to any representations or objections. The Secretary of State would
have the power, among others, to modify the conditions of the license if, on
investigation, under the Fair Trading Act 1973, the Commission concluded that
matters investigated by it in relation to water or wastewater services operated
against the public interest.
    
 
     A license may also be revoked or transferred to another company in
circumstances specified under law or in the license. These circumstances include
the failure to comply with an enforcement order made by the Secretary of State
for the Environment or the Director or the inability of the relevant water and
wastewater company to pay its debts.
 
  WESSEX WATER SERVICES' LICENSE
 
   
     Wessex's license continues indefinitely, or until such time as the
Secretary of State revokes Wessex's license after ten years' advance notice. The
effective date of revocation, under the terms of Wessex's license, cannot occur
prior to 2014. If at any time Wessex becomes insolvent or it is determined that
Wessex has committed such a serious violation of its duties so as to make it
inappropriate for it to continue to hold the license, the Secretary of State or,
with his consent, the Director, may seek a special administration order, under
the terms of which Wessex's affairs, business and property may be transferred to
another company to ensure that Wessex's appointed functions can be carried out.
In either event, the legislation provides for Wessex's assets to be transferred
to the new replacement appointee on terms approved by the Director or the
Secretary of State, including the consideration to be paid by the new appointee.
The special administration provisions in effect subordinate members' and
creditors' rights to the achievement of the purposes of the special
administration order. The license sets out the charging formula
    
                                       74
<PAGE>   80
 
   
imposed on Wessex, which is subject to review every five years. The formula is
tied to the retail price index plus an adjustment factor, which can be positive,
zero or negative. The adjustment factor is set by the Director on a case-by-case
basis for each company at the review to bring the companies in line with the
target rate of return set by the Director. The license also regulates the fees
that Wessex may charge new customers upon connecting them to the water or
wastewater network for the first time. Wessex must fix and publicize its rates
for the provision of water and wastewater services and for first-time provision
of water supply and wastewater services and must not discriminate against any
individual or class of customer with respect to charges.
    
 
   
     Wessex is required to maintain sufficient financial and managerial
resources to carry out the appointed business and necessary investment. The
license requires it to publish separate accounts showing its regulated business
separately from all other businesses and activities and additional accounts
prepared on a current-cost basis with respect to the same period. Regulated
businesses, such as Wessex, are subject to business practices limitations, such
as restrictions on cross-subsidies, that restrict affiliate dealings and promote
competitive contracting. The license also requires Wessex to put in place
financial structures protecting a sufficient amount of its assets so that its
water and wastewater services could still be provided in the event of Wessex's
insolvency.
    
 
   
     Wessex's license includes service targets that are monitored by the
industry regulator. The license also requires Wessex to pay annual fees, based
on Wessex's revenues, which are intended to cover the costs of the regulation of
the water industry. In 1998, Wessex paid approximately $665,000 in such fees.
    
 
   
     The license has been modified as a condition of regulatory clearance of
Azurix's acquisition of Wessex to address regulatory concerns arising out of the
acquisition. In particular, the modification strengthens the financial
independence and independent management of Wessex Water Services' regulated
business, providing water supply and wastewater services, by imposing the
following:
    
 
     - Restrictions on transfers of assets, guarantees, intercompany loans and
       loans containing cross-default provisions
 
     - A requirement that transactions with associated companies must be entered
       into on an arm's length basis at market rates
 
     - A requirement to maintain an investment grade rating for corporate debt
       of Wessex Water Services
 
   
     - A requirement that Wessex issue a variable-coupon bond by December 31,
       2000 and use its reasonable efforts to list such bonds on the London
       Stock Exchange
    
 
   
     - A requirement that information be published similar to that of a public
       company
    
 
   
     The license as modified also requires a dividend policy to be agreed upon
with the Director that ensures that Wessex Water Services retains sufficient
funds to finance its core activities and which should be expected to reward
efficiency and the management of economic risk. The license also requires Wessex
Water Services to conduct its regulated business as if a separate public limited
company. In addition, Wessex is obligated to obtain undertakings from its
ultimate parent company. If those undertakings are not, at any time, in place or
if there is an unremedied breach of them, then, in addition to potential
enforcement action, Wessex may not, without the Director's consent, enter into
any contract with its parent. To comply with this obligation, Azurix Europe and
Atlantic Water Trust have given a holding company undertaking that requires,
among other things, that Azurix Europe and Atlantic Water Trust give Wessex
Water Services all information necessary for it to carry out its obligations and
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.

<PAGE>   81
 
  TARIFF RATES
 
   
     The Director regulates prices and service levels. Price controls applicable
to each water and wastewater company are subject to reviews by the Director
every five years, known as periodic reviews, but both the Director and the
individual company may seek an interim determination to adjust price limits
between the periodic reviews in limited circumstances.
    
 
   
     Unlike "rate of return" economic regulation, such as exists for many U.S.
industries, regulation in the United Kingdom generally uses forms of "price
limitation." This is intended to reward companies for efficiency and quality of
service to customers. The U.K. regulatory system generally allows companies to
retain for a period any savings attributable to efficiencies that they are able
to achieve. These are then passed on to customers in lower price limits in the
next periodic review. The main instrument of economic regulation is a price
limitation formula set out in each company's license. This formula limits
average 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 maintain
assets and an appropriate return on capital.
    
 
   
     During the last 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 are 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 L8
billion, or approximately $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 proposed, in the case of Wessex, that expected average
household bills, in real terms, could be over 17.5% lower in 2000-2001 than in
the previous year, but that bills overall would rise, by 2004-2005, to a level
exhibiting only a small reduction compared with the expected 1999-2000 bill.
This would constitute a material increase in prices following the one-time
reduction in 2000-2001. The Director's proposal preceded, and therefore 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
expenditures, the average overall scope for efficiency is between 10% and 15%
over the five-year period. They also assumed a post-tax cost of capital of 5.25%
for all but the smaller companies, although the Director more recently has
suggested a figure of around 4.75% may be more appropriate.
    
 
     The Director held formal meetings with each of the water and wastewater
companies during January and February 1999 to discuss the issues raised by a
proposed price reduction including the responses of the public. In its April
1999 business plan filed with the Director, Wessex proposed stable prices from
1999-2000 to 2000-2001, with prices gradually increasing to 18% higher than
current levels in 2005, primarily to fund capital expenditures mandated by the
new environmental standards. The business plan will be considered by the
Director as part of the periodic review. The Director has stated that he will
publish his
                                       76
<PAGE>   82
 
   
draft determination of new price limits to run from 2000 to 2005 in July 1999,
with his final decisions made in November 1999. These may differ materially from
his original proposal. If a company disagrees with the Director's price
determination, it may challenge his proposal by requesting a reference to the
Competition Commission. On such a reference the determination of the Commission
will be final. Although we are unable to predict the precise outcome of the
current U.K. periodic review, if Wessex were required to cut its prices as
originally proposed by the Director, Wessex's regulated operating revenues,
which represent approximately 90% of total operating revenues, would be reduced
by approximately 17.5% compared to 1999-2000 and its earnings would be reduced
materially. However, we would not expect that this would have a material adverse
effect on Azurix's financial position. At the time of the acquisition of Wessex,
we took into consideration the pending rate review in our valuation of Wessex.
    
 
   
  CHANGES TO REGULATORY REGIME
    
 
     On June 30, 1997, the U.K. Government launched a review of the framework
for the regulation of all utilities, and in March 1998 set out its proposals in
a consultation paper. In July 1998, following the consultation, the U.K.
Government published its response. Among other things, it suggested that:
 
   
     - Consumer protection should be the Director's primary duty, achieved
       wherever possible and appropriate through promoting effective
       competition, but also taking into account the need to ensure that
       regulated companies are able to finance the carrying out of their
       functions.
    
 
   
     - There should be consumer representative bodies to promote consumer
       interests.
    
 
   
     - A clearer link should be made between the prices utilities may charge and
       the customer service standards they achieve.
    
 
   
     - Full information should be available on companies' performance on
       customer service standards and on the links between this performance and
       the remuneration of directors.
    
 
   
     - Ministers should issue statutory guidance on social and environmental
       objectives.
    
 
     On publishing the response, the Secretary of State for Trade and Industry
stated an intention to introduce legislation to implement the proposals as soon
as parliamentary time permits. In his March 1999 Budget Speech, the Chancellor
of the Exchequer announced that the Deputy Prime Minister will review
competition in the water industry.
 
   
     Separately, the Competition Act 1998 will become effective in 2000. This
will, among other things, increase the ability of the UK regulatory authorities,
including the Director in relation to water and wastewater services, to
investigate and take action against anti-competitive agreements and conduct. In
particular, companies found to have violated the new prohibitions of
anti-competitive agreements and abuse of a dominant position may be fined up to
10% of their U.K. turnover. U.K. competition law, in the Fair Trading Act 1973,
also enables monopoly situations, as defined, to be investigated by the
Competition Commission. Where these are found to operate contrary to the public
interest, the Secretary of State has extensive powers to take action to remedy
or prevent those adverse effects, including the power to order businesses to be
divided.
    
 
  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.
 
   
     Under the Water Industry Act 1991, water supplied for domestic or food
production must be wholesome at the time of supply. The Drinking Water
Inspectorate is responsible for ensuring that water supplies meet this standard
as well as the standards set out in the U.K. Water Quality Regulations. Breach
of these requirements can lead to regulatory or criminal liability if the water
supplied causes loss or
    
 
                                       77
<PAGE>   83
 
   
damage. Water companies are required to carry out statutory sampling of water
supplied to customers and must provide public information on drinking water
quality. The licensed Inspectorate conducts technical audits to assess annually
the quality of the drinking water supplied by the licensed companies. If any
company fails to meet the relevant water quality standards, the Inspectorate may
require it to take any necessary remedial action.
    
 
   
     Under the Water Resources Act, the Environment Agency may require persons
to take precautions against pollution, may prohibit or restrict activities
likely to cause pollution in areas designated by the Secretary of State for the
Environment and may issue consents to discharge matter from a drain or sewer.
When reviewing existing consents and issuing new ones, the stated practice of
the Environment Agency is to seek to set conditions at the level required to at
least maintain and, where appropriate, improve the quality of the receiving
waters.
    
 
   
     The activities of the U.K. water and wastewater companies are also affected
by the requirements of European Union directives, including the Drinking Water
Directive, the Bathing Waters Directive and the Urban Wastewater Treatment
Directive, each of which has been brought into force in the United Kingdom. The
environmental systems that Wessex has in place are designed to comply with
European Union and U.K. requirements.
    
 
   
     In May 1997, the Secretary of State for the Environment announced a review
to examine ways in which environmentally damaging abstractions can be equitably
curtailed. The review will consider arrangements to reduce abstractions under
existing licenses and for revoking licenses in areas where pumping causes
significant environmental damage. He has also announced that the Director will
be setting mandatory targets to reduce leaks from water supplies, which will be
reviewed annually. Failure to meet the targets would carry penalties and could
ultimately lead to a water and wastewater company being put into the hands of an
administrator appointed by the Director. In addition, in March 1999 the U.K.
Government announced that new water abstraction licenses will include time
limits and limits may be imposed on existing licenses.
    
 
   
     In view of the age and history of many sites owned by Wessex, Wessex may
incur liability for sites that are found to be contaminated, resulting in
increased costs of managing or cleaning up such sites. Environmental legislation
requires the polluter (or if the polluter cannot be found, the owner or
occupant) of contaminated land to clean up any contamination which causes, or is
likely to cause, significant harm to the environment. Polluters are also
required to clean up any pollution of water sources. Other proposals that 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 that 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.
 
                                       78
<PAGE>   84
 
   
     Under the Argentine Constitution, the provision of water services at the
local level generally is within the authority of the provinces and
municipalities. In the Province of Mendoza, for example, the Ministry of Public
Works and the Environment is granted general authority over all non-agricultural
water services, and environmental regulation. Concessions for the provision of
water services are granted by the provincial government by statute and decree,
with oversight vested in the Ministry of Public Works and in a special purpose
regulatory body known as EPAS. Decisions of EPAS may be reviewed by the Minister
of the Ministry of Public Works and the Governor of the Province of Mendoza. In
the Province of Buenos Aires, these duties are carried out by the Organismo
Regulador Bonarense de Aguas y Saneamiento, a unit of that province's Ministry
of Public Works.
    
 
  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 eventually 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. To date, however, this treaty has not been ratified by Argentina.
    
 
   
     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, the local regulatory agency, known as EPAS, and
the Ministry of Public Works regulate the provision of services and the setting
of tariffs.
    
 
   
     In Mendoza, tariffs are proposed by EPAS, and then submitted to the
Minister of the Ministry of Public Works, the provincial legislature and the
Governor for approval. EPAS must recommend rate regimes with an aim to reflect
efficient costs of operations, maintenance and expansion and renewal of the
water system, including debt service. EPAS also strives to promote rational and
efficient use of services and resources leading to a balance of supply and
demand, and to address sanitation and social objectives. EPAS is authorized to
establish tariff rates that require some users to pay rates that subsidize the
cost of providing service to other users. Argentine law provides that in setting
tariffs, EPAS must take into account costs of operations, maintenance,
amortization of services and a "reasonable" rate of return for the
concessionaire in the context of an efficient level of operation. The basic
tariff regime is to be reviewed every five years.
    
 
   
     The current tariff schedule imposes a fixed monthly charge per customer,
based on a formula which takes into account the customer's land area, types and
size of structures and uses of the land, that normally will remain unchanged
until the new tariff regime is implemented. Changes in current tariffs are
allowed for several enumerated reasons, including if operating costs increase or
decrease by 4% as reflected in official national indices, if there is a change
in the national "convertibility law" which establishes a 1:1 exchange rate of
the peso with the dollar, if there are changes in the capital program due to
government or regulatory reasons or if there are changes in taxes, other than
income taxes.
    
 
   
     A new tariff regime is to be implemented in Mendoza within the next several
years based on a metered charge per liter of water used. The concession contract
contains assurances that the concessionaire will receive the same level of
revenue as under the prior regime, thus allowing the concessionaire to retain
efficiency gains and pass through changes in costs. The contract contains no
provision for direct pass-through for inflation or revisions in tariffs for
capital expenditures. The concessionaire may request adjustments to the new
tariff if any of the following occurs:
    
 
     - The new tariff lowers consumption significantly
 
                                       79
<PAGE>   85
 
     - The concessionaire shows that the new tariff does not promote rational
       use of the assets and capital employed for the operations of the company
       or does not allow it to carry out the obligations of the company
 
     - The concessionaire shows that most of the benefits of cost reductions are
       inuring to consumers
 
   
     The Province of Buenos Aires employs a similar regime. There, both the
governing law and the concession contract provide that tariff modifications may
not be used to penalize a concessionaire if it operates more efficiently than
expected.
    
 
  ENVIRONMENTAL MATTERS
 
   
     Beginning in the early 1990s, Argentina began addressing environmental
matters systematically at the federal level. For instance, in 1991 the Argentine
government enacted a law establishing the Secretariat of the Environment and
calling for a balancing of economic development with the conservation of natural
resources, the improvement of the environment and the prevention and
amelioration of the effects of pollution. In August 1994, the Argentine
Constitution was amended to assure the right of all residents of Argentina to a
healthy environment and granted the Argentine government authority to establish
minimum standards of environmental protection which are to be implemented by the
provinces. The 1994 amendments to the Constitution also provide that damage to
the environment must be repaired immediately in accordance with applicable law,
and prohibit the importation of actually or potentially toxic or radioactive
waste. In 1995, the Argentine government initiated a program to protect the
environment by promulgating rules regarding water, land, air and noise pollution
and hazardous substances.
    
 
     Throughout Argentina, the provinces take the lead in regulating discharges
of pollutants into waterways. These provinces typically set permissible
standards for pollutant levels in the discharges, issue permits and enforce
them. In Mendoza, wastewater discharges are regulated at the provincial level by
the Ministry of Public Works, which has adopted laws respecting water quality.
As in most provinces in Argentina, the Ministry of Public Works issues permits
and regulates discharges of pollutants into water bodies. In addition, the
concessionaire is required to comply with the drinking water quality standards
set by the concession contract and enforced by EPAS. The Argentine government
can enforce the provisions of the Argentine Civil and Criminal Codes against the
concessionaire.
 
     Most provinces in Argentina have also adopted their own regulations for air
and waste as well. The various provincial laws establish different compliance
and enforcement requirements.
 
MEXICAN REGULATORY MATTERS
 
  WATER PROVISION ISSUES
 
   
     Article 27 of the Mexican Constitution reserves water resources to the
nation. Article 115 of the Mexican Constitution places responsibility for
providing public services, including water and wastewater treatment, on the
municipalities with the participation of the state when required by law. The
Ministry of Environment, Natural Resources and Fisheries, through the National
Water Commission, is responsible for:
    
 
     - Assigning water rights and discharge rights to users and assessing the
       relevant fees
 
     - Enforcing water-related environmental regulations
 
     - Planning the efficient development of water resources
 
     - Developing regulatory, legal and financial structures for water
       concessions at the municipal level with an emphasis on private
       participation
 
     - Providing technical assistance to local water authorities and advising on
       project feasibility
 
     - Providing financial support for priority water projects, particularly in
       low-income areas
 
                                       80
<PAGE>   86
 
     The states and municipalities are responsible for setting conditions for
concessions and for establishing a tariff structure for all customer groups,
collecting payments from customers and paying the National Water Commission for
use of water rights. The Cancun concession is regulated by Concession Integral
de los Servicos de Agua Potable, Alcantarillado Sanitario y Saneamiento,
referred to as CAPA, an agency of the State of Quintana Roo. One of the
requirements of the concession is that the concessionaire achieve and maintain a
95% connection rate for water and wastewater for the population. Changes to the
connection rate requirement will be subject to the mutual consent of both CAPA
and the concessionaire.
 
   
     The Governor of the State of Quintana Roo appoints the members of CAPA. If
the Governor is not supportive of the concessionaire, CAPA may be less inclined
to approve concessionaire initiatives and less understanding of problems it
encounters. Azurix believes Desarrollos Hidraulicos, the concessionaire, has
good relations with the state's new governor.
    
 
  TARIFF RATES
 
     The tariff rates are set by CAPA and are based on the principle of full
recovery of operations and maintenance costs and can be revised to maintain the
economic equilibrium of the concession. There is no provision that tariffs
should provide a return on equity or permit the concessionaire to earn a profit.
 
     Initial tariffs were set when the concessionaire was first awarded the
concession in October 1993. At current levels, the tariffs are sufficient to
cover cost of operations, capital expenditures required under the concession and
return on investment. These expenditures should not necessitate a real tariff
increase over the term of the concession. However, should significant,
unexpected capital expenditures be required, the concessionaire can propose to
CAPA a tariff increase.
 
   
     CAPA has indicated that it intends to change the tariff rate in the near
term to eliminate the cross-subsidy between water and wastewater. Currently,
wastewater service is charged a flat rate of 20% of the water bill, regardless
of actual usage. This would have the effect of increasing wastewater rates and
reducing water rates. If the concessionaire wants to increase rates in real
terms, it will be required to submit a rate case to CAPA, with supporting
economic and financial documents explaining the reason for the increase. In all
cases, the real rate for the residential and communal customer classes shall not
exceed the combined operation and maintenance costs of supplying those
customers. The concession will be evaluated every five years to determine
whether real tariff increases are justified. However, the concessionaire may
propose real increases at any time, though CAPA's consent must still be
obtained.
    
 
     Under the terms of the concession amendments, the concessionaire is
permitted to disconnect a customer for non-payment.
 
  ENVIRONMENTAL MATTERS
 
     The concessionaire has represented to Azurix that it is and has been in
compliance with all state and federal environmental standards associated with
the operation of the concession and that there are no outstanding non-compliant
environmental issues with the state and federal agencies associated with the
concession's operation. If the representation made by the concessionaire is
incorrect, then any environmental liability will be a liability of the
concessionaire. In any event, the concessionaire and an affiliate of the former
shareholders must indemnify Azurix up to $300,000.
 
   
     The wastewater plants operated by the concessionaire are designed to
discharge an effluent containing no more than 30 milligrams per liter of total
suspended solids and biochemical oxygen demand. The Mexican federal quality
criterion for the saltwater injection discharge that is operated by the
concessionaire is 70 milligrams per liter of total suspended solids and
biochemical oxygen demand. With the completion of the plant under construction,
the existing biosolid management system will need to be modified or expanded to
manage the disposal of the additional volume of biosolids that will be produced,
and other environmental systems will need to be reevaluated for ongoing
operations. The majority of the planned capital expenditures is dedicated to the
improvement of the wastewater collection and treatment system,
    
 
                                       81
<PAGE>   87
 
and we believe that the amounts planned are sufficient to meet treatment goals
and environmental regulations.
 
U.S. REGULATORY MATTERS
 
   
     Philip Utilities, which we acquired on May 18, 1999, has operations in the
United States. The business sectors in which we operate, or intend to operate,
in the United States are generally highly regulated by national, state and local
laws and regulations.
    
 
  TARIFF RATES
 
     In the United States, the rates for water and wastewater services are
generally subject to state and local laws and regulation. Although the system is
highly fragmented among jurisdictions, most jurisdictions in the United States
utilize "rate of return" economic regulation in setting water and wastewater
rates. Under rate of return economic regulation, the service provider is allowed
to recover its reasonable and necessary operations and maintenance expenses, and
a recovery of and a reasonable return on its invested capital. In most
jurisdictions, a water or wastewater service provider is required to keep a
current set of tariffs on file with the governing regulatory authority. A
service provider generally can charge less than the approved tariffs. Typically,
a service provider cannot change its rates without the approval of the governing
regulatory authority. We can give no assurance regarding our ability to obtain
approvals for rate changes, given the vast number of regulatory authorities with
jurisdiction over water and wastewater service in the United States, and the
fact that decisions regarding rate changes are often subject to political, as
well as economic, factors.
 
  DRINKING WATER QUALITY
 
     The Safe Drinking Water Act directs the EPA to set drinking water standards
for the approximately 55,000 community water supply systems in the United
States. The Safe Drinking Water Act Amendments of 1996 bring important changes
to the regulation and financing of water systems. The amendments have several
potentially significant regulatory initiatives, which include the following:
 
     - Recent adoption of two rules that may require more sophisticated
       treatment. First, the disinfectants and disinfection by-products rule,
       establishes maximum residual disinfectant levels for chlorination and
       maximum contaminant level goals for potentially harmful disinfection
       by-products. Second, the enhanced surface water treatment rule focuses on
       treatment requirements for waterborne pathogens, particularly
       cryptosporidium.
 
   
     - A requirement that the EPA list 30 previously unregulated contaminants
       for monitoring, risk assessment and potential regulation at least once
       every five years. The new Act also specifies that the EPA shall study
       radon, arsenic and sulfates and propose rulemakings in 1999, 2000 and
       2001, respectively, if the EPA determines that these chemicals threaten
       the public health. Such a program poses the risk of additional
       contaminants being regulated as the EPA implements this research, with
       the attendant risks of potentially increased capital and operational
       costs.
    
 
     - Adoption of regulations to reduce lead and copper in drinking water.
       Water providers that exceed specified levels of lead and copper in
       drinking water may be required to perform additional monitoring and
       develop measures to reduce the lead and copper content.
 
   
     The EPA has other long-term plans to develop regulations governing the
treatment of drinking water, such as the recycling of filter backwash into
influent streams at public utilities and additional groundwater disinfection. It
is unclear what precise form these and other regulations will take, so potential
regulatory risks and costs of compliance cannot be evaluated at this time. As is
true for any drinking water provider, by operating water assets in the United
States, we 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.
    
 
                                       82
<PAGE>   88
 
  ENVIRONMENTAL MATTERS
 
     Among other things, environmental laws and regulations in the United States
generally set requirements for:
 
     - The quality of the discharges from treatment facilities
 
     - The handling and disposal of biosolids from treatment facilities
 
     - The management of associated materials and wastes
 
     - Good housekeeping practices for the management and monitoring of the
       operations
 
     We intend to invest in companies or projects that operate in material
compliance with environmental laws and regulations. It is impossible, however,
to predict how the precise regulatory framework governing companies in which we
will invest will operate.
 
     Changes in environmental laws and regulations, or in the level of their
enforcement, may adversely impact our financial results. These adverse impacts
could cause our actual financial results to differ materially from those we
project, forecast, estimate or budget. Moreover, changes in these laws and
regulations may require improvements in order to remain in compliance that can
result in additional capital and operating costs. Environmental protection
statutes in the United States typically provide for the imposition of
substantial civil and criminal penalties, as well as the possibility of permit
revocation and corrective action orders, for violations of their requirements.
These laws may also provide for retroactive, strict liability without regard to
a party's negligence or fault.
 
     The Federal Water Pollution Control Act, known as the "Clean Water Act,"
establishes a system of standards, permits and enforcement procedures for the
discharge of pollutants from industrial and municipal wastewater sources. The
law requires permits for discharges from water treatment facilities and sets
treatment standards for industries and wastewater treatment plants. Discharge
permits issued under the Clean Water Act are subject to renewal once every five
years. When discharge permits are renewed and reissued, it is customary for the
EPA or the state agency issuing the permit to impose more stringent discharge
limitations in the new permit. In addition, the EPA and the states have been
establishing new standards for bodies of water that receive wastewater treatment
plant discharges and these new standards may result in the imposition of more
stringent effluent limitations as discharge permits are renewed. Compliance with
these requirements is monitored closely and the Clean Water Act provides the EPA
with an array of enforcement mechanisms for companies that fail to comply,
including penalties and injunctive relief. Additionally, the EPA has recently
published regulations of the use and disposal of biosolids when they are applied
to land or incinerated. Although controls on biosolid disposal may be tightened,
we believe it unlikely that the EPA would take drastic measures such as banning
the land application of biosolids. Although we cannot predict the nature of
these and other regulations under the Clean Water Act, we do not believe that
such regulations will materially harm our business.
 
   
     Other U.S. environmental laws and regulations may also impact Azurix. These
include the Clean Air Act, the Resource Conservation and Recovery Act and the
Comprehensive Environmental Response, Compensation and Liability Act. Generally
speaking, responsibility for implementing and enforcing the regulations
promulgated by the EPA under the Clean Air Act and the RCRA rests with
individual states, whereas the 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 the RCRA and consequently become subject to more
stringent handling and disposal requirements imposed under the RCRA.
    
 
                                       83
<PAGE>   89
 
     We believe that Azurix possesses the expertise necessary to comply with all
U.S. environmental laws applicable to Azurix's operations. We also expect that
our U.S. operations will be subject to a comprehensive environmental auditing
program similar to the program that Wessex has implemented for operations in the
United Kingdom that is designed to provide early identification of potential
environmental problems and to provide reasonable assurance that identified
problems are properly and promptly addressed. Nevertheless, there can be no
assurance that our operations will comply with all environmental laws at all
times.
 
CANADIAN REGULATORY MATTERS
 
   
     Philip Utilities has operations in Canada. Water and wastewater treatment
operations in Canada are subject to comprehensive federal, provincial and local
laws, regulations and guidelines pertaining to the provision of drinking water
and wastewater treatment services, as well as protection of the environment.
These laws and implementing regulations and guidelines establish standards for
the quality and quantity of effluent discharged from wastewater treatment
facilities, the handling and disposal of biosolids and other generated wastes
and materials, and the treatment and distribution of drinking water to
customers. Water and wastewater treatment facilities may only be constructed
after required environmental permits, certificates and approvals have been
obtained from appropriate governmental agencies. These facilities must then be
operated in compliance with the terms and conditions found in those permits,
certificates and approvals. Some Canadian provinces also regulate and control
the quality of drinking water, using standards relating to the design,
construction and operation of water facilities that may be more burdensome than
federal requirements. Moreover, there are extensive federal and provincial laws,
regulations and guidelines relating to the proper management and safe control of
biosolids and other wastes and materials that are accumulated at water or
wastewater treatment facilities and require proper disposal. The failure to
comply with these laws, regulations and guidelines or any applicable permits,
certificates and approvals may result in the assessment of fines, penalties or
administrative orders.
    
 
   
     We believe that technical and operating personnel at Azurix possess the
expertise necessary to ensure that any water or wastewater treatment concessions
acquired in Canada will be operated in compliance with applicable Canadian laws,
regulations and guidelines, but there can be no guarantee that these operations
will comply with all environmental laws, regulations and guidelines at all
times. Any new environmental laws, regulations and guidelines, changes to
existing laws, regulations and guidelines, or more stringent terms and
conditions in permits, certificates or approvals relating to facilities we
operate may result in additional regulatory compliance costs that may or may not
be recoverable through rate increases. Nevertheless, we do not expect any new or
changed laws, regulations and guidelines or the modification of any permits,
certificates or approvals to be any more burdensome to the operations of Azurix
than any other water and wastewater treatment services company performing
similar operations in Canada.

of the role as Chairman and CEO of Azurix, in addition to her role as Vice
Chairman of Enron. The agreement provides for an annual salary of not less than

percent of Enron International's after-tax net income subject to adjustment in
the sole discretion of Enron's Chairman and CEO, taking into consideration
after-tax net income and funds flow targets set each year by the Board of

The agreement also provides for full vesting of specific grants and awards made

Mark's termination of employment.
    
 
   
     Rodney L. Gray entered into an employment agreement with Azurix effective

Under the terms of the agreement, upon commencing employment, Mr. Kulpecz was
granted 100,000 Enron stock options that have a ten-year term and vest one-third
on each anniversary of the date of grant and 30,000 Enron stock options which

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,

STOCK PLAN
 
     We have adopted a stock incentive plan. Grants of incentive stock options
and nonqualified stock options and awards of restricted stock may be made
pursuant to the stock plan. At any particular time, the number of shares of
common stock issued under the plan plus the number of shares of common stock
issuable upon the exercise of all outstanding stock options under the plan may
not exceed 15% of the total number of shares of common stock then outstanding,
assuming the exercise of all outstanding options. The stock plan will be
administered by the Stock Plan Committee, which consists of Rebecca P. Mark,
Kenneth L. Lay and Jeffrey K. Skilling. The exercise price for an option granted
under the stock plan will be determined by the Stock Plan Committee and will be
no less than the fair market value of the common stock on the date that the
option is granted. If our outstanding common stock is adjusted because of a
                                       90
<PAGE>   96
 
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
 
     During 1998, there were no options held, granted or exercised. On February
2, 1999, Azurix granted options to purchase a total of 7,800,150 shares of
common stock. The following table sets forth information regarding options
granted to the Named Executive Officers on February 2, 1999.

(1) These options are subject to vesting based on the following schedule:
    Rebecca P. Mark -- 25% per year over four years; Rodney L. Gray -- 20% per
    year over five years; Amanda K. Martin -- 25% per year over four years; Alex
    Kulpecz -- 20% per year over five years; and Colin F. Skellett -- 33 1/3%
    per year over three years.
 
(2) Each of these options was granted pursuant to our stock incentive plan and
    is subject to the terms of the stock incentive plan as described above.
    These options were granted at an exercise price equal to the fair value of
    our common stock as determined by our Board of Directors on the date of the
    grant.
 
(3) The 0%, 5% and 10% assumed annual rates of compounded stock price
    appreciation are mandated by the rules of the SEC. There can be no assurance
    that the actual stock price appreciation over the ten-year option term will
    be at the assumed 0%, 5% or 10% levels or at any other defined level. Unless
    the market price of the common stock appreciates over the option term, no
    value will be realized from the option grants. The potential realizable
    value is calculated by assuming that the fair market value of the common
    stock on the date of grant of the options appreciates at the indicated rate
    for the entire term of the option and that the option is exercised at the
    exercise price and sold on the last day at the appreciated price.
 
     In addition to the option grants to the Named Executive Officers in the
table above, Azurix granted options to purchase a total of 2,200,150 shares of
common stock at an exercise price of $16.72 per share to other employees with
vesting schedules generally providing for vesting over three to five years. All
of these options expire ten years after the grant date of February 2, 1999.

     In approving the grants described above, the Stock Plan Committee sought to
provide incentives in addition to compensation to Azurix's employees to devote
their utmost effort and skill to the advancement and betterment of Azurix by
providing such employees with an opportunity to participate in the ownership of
Azurix and thereby have an interest in the success and increased value of Azurix
as well as to enhance Azurix's ability to retain the services of its key
employees. As a member of the Stock Plan Committee, Rebecca P. Mark participated
in approving these grants, except with respect to the grant of options to
herself.
 
   
     In addition to the grants of stock options described above, our Board of
Directors has authorized additional grants, conditioned on the completion of the
offering and effective as of the closing of the offering, of options to purchase
an aggregate of 626,500 shares of common stock to employees who recently joined
Azurix. These options will have an exercise price equal to the initial public
offering price, will generally vest over three to five years and will be
exercisable for ten years after the date of grant.

      TRANSACTIONS WITH ENRON, ATLANTIC WATER TRUST AND MARLIN WATER TRUST
    
 
   
     In 1998, there were significant transactions among us, Enron, Atlantic
Water Trust and Marlin Water Trust. For purposes of governing these ongoing
relationships, we will enter into, or continue in effect, various agreements and
relationships, including those described below. Some of the agreements
summarized below will be included as exhibits to the registration statement of
which this prospectus is a part. The following summaries of these agreements
discuss the material provisions of these agreements and are qualified completely
by reference to such exhibits which we incorporate in this prospectus by
reference.
    
 
     During 1998, Azurix indirectly acquired all of the outstanding ordinary
share capital of Wessex, and Enron contributed to Azurix the outstanding common
stock of a subsidiary that in June 1998 acquired a 32.1% ownership interest in
Obras Sanitarias Mendoza. In December 1998, Enron contributed Azurix to Atlantic
Water Trust and Marlin Water Trust acquired a 50% voting interest in Atlantic
Water Trust. Enron retained a 50% voting interest in Atlantic Water Trust.
 
   
     On February 25, 1999, in connection with the Cancun acquisition, Enron
advanced to Azurix $15.0 million, which was used by Azurix to fund a loan to
Cancun. On March 24, 1999, Enron advanced to Azurix $13.5 million to fund the
Cancun acquisition, which closed on that date.
    
 
     Enron currently provides office space to Azurix and various services such
as computer hardware and software and support services such as risk management,
accounts payable, payroll and information technology services. Costs are
allocated to Azurix based upon usage, or where no direct method can be
efficiently applied due to administrative burden, upon factors such as
annualized payroll or employee headcount. Employees, other than Wessex
employees, are covered by various employee benefit plans of Enron such as
retirement, stock option, medical, dental, life insurance and other benefit
plans. These costs are allocated to Azurix based upon Enron's costs of
administering and providing the benefit plans.
 
   
     Enron has paid on behalf of Azurix approximately $72 million to fund our
general, administrative and operating expenses, from our inception through May
21, 1999, in addition to capital expenditures. This includes $28.5 million
advanced to us by Enron in connection with our investment in Cancun, as well as
advances relating to the services described above. The amount paid by Enron is
non-interest bearing and has no maturity date. We intend to use a portion of the
net proceeds that we receive from the offering to repay this amount. See "Use of
Proceeds."
    
 
ACQUISITION OF WESSEX
 
   
     On October 2, 1998, Azurix, through its Azurix Europe, acquired over 90% of
the outstanding ordinary share capital of Wessex. On that same date, Azurix
Europe issued notices to the remaining Wessex ordinary shareholders, informing
them that it intended to exercise its rights under the English Companies Act to
acquire compulsorily all of the outstanding ordinary shares not held by Azurix
Europe. The compulsory share acquisition was completed in November 1998. The per
share price paid to Wessex shareholders was L6.30. The total cost of the Wessex
acquisition, including transaction costs, was $2.4 billion, plus the assumption
of $481.5 million of existing Wessex debt. The cost included cash consideration
paid to Wessex shareholders, net of $1.7 million cash acquired, and the issuance
of loan notes to Wessex shareholders in the face amount of $119.8 million.
    
 
     The acquisition was financed through capital contributions from Enron Water
(Holding) L.L.C., formerly Azurix's parent company and a wholly owned subsidiary
of Enron, totaling $1.6 billion and the issuance of $0.8 billion in debt by
Azurix Europe. The financing of the Wessex acquisition by Azurix, through Azurix
Europe, was as follows:
 
     - Enron made a $500.2 million capital contribution to Enron Water (Holding)
       L.L.C.
 
     - Enron borrowed $1.1 billion under a revolving credit facility, which
       Enron loaned to Enron Water (Holding) L.L.C.
 
     - Enron Water (Holding) L.L.C. made a capital contribution of these funds
       to Azurix, and Azurix, through a wholly owned subsidiary, made a capital
       contribution of these funds to Azurix Europe
                                       93
<PAGE>   99
 
     - Enron lent L73 million ($124.4 million) to Azurix Europe under a senior
       loan agreement
 
   
     - Enron lent L72 million ($122.7 million) to Azurix Europe under a
       short-term, senior, unsecured credit facility, which loan, together with
       $2.1 million of accrued interest, was subsequently repaid with the
       proceeds from the sale of UK Waste in December 1998
    
 
     - Azurix Europe borrowed L252 million ($429.3 million) under the existing
       senior credit facility
 
     - Azurix Europe issued seven-year, senior, unsecured loan notes in the face
       amount of L70.5 million ($119.8 million) to Wessex shareholders who
       elected to take loan notes instead of cash
 
   
     In connection with regulatory clearance of the acquisition of Wessex, Enron
and Wessex's immediate parent, Azurix Europe, agreed to make 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. See "Regulatory
Matters -- U.K. Regulatory Matters."
    
 
ACQUISITION OF INTEREST IN ATLANTIC WATER TRUST
 
     In December 1998, Enron contributed Azurix to Atlantic Water Trust, a
Delaware business trust, by contributing Enron Water (Holding) L.L.C. and
merging it into Azurix. In connection with Enron's contribution, Marlin Water
Trust acquired for $1.149 billion a 50% voting interest in Atlantic Water Trust,
with Enron retaining a 50% voting interest. Of the $1.149 billion paid by Marlin
Water Trust, $900 million was used to repay a portion of the indebtedness
incurred by Enron and its affiliates in connection with the Wessex acquisition.
See "Principal and Selling Stockholders -- Atlantic Water Trust."
 
CONFLICTS OF INTEREST
 
   
     Atlantic Water Trust currently owns all of Azurix's outstanding common
stock. Following completion of the offering, Atlantic Water Trust will own
approximately 68.7% of our outstanding common stock, 64.1% if the underwriters'
over-allotment option is exercised in full. Each of Enron and Marlin Water Trust
owns a 50% voting interest in Atlantic Water Trust. To date, Enron has appointed
all of the directors of Atlantic Water Trust and Azurix, although Marlin Water
Trust at any time has the right to elect or replace half of the directors of
Atlantic Water Trust and currently up to half of the Azurix directors. Following
the offering, as long as Atlantic Water Trust owns a majority of our outstanding
voting 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 voting stock held by persons other than Atlantic Water
Trust, Enron and its affiliates. Furthermore, Marlin Water Trust, with the
consent of the holders of a majority of our outstanding voting 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.
In each case, Marlin Water Trust's right to designate directors shall be reduced
by the number of directors that may be elected by preferred stock entitled to
elect directors as a class. 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. 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 will control
the outcome of corporate actions requiring stockholder approval, including the
approval of transactions involving a change in control of Azurix.
    
 
     Currently, a majority of our directors are also directors or officers of
Enron, a situation that may create conflicts of interest. The directors and
officers of Enron have fiduciary duties to manage Enron, including its
investments in subsidiaries and affiliates such as Azurix, in a manner
beneficial to Enron and its stockholders. Similarly, the directors and officers
of Azurix have fiduciary duties to manage Azurix in a manner beneficial to
Azurix and its stockholders. In some circumstances, the duties of these
directors and officers of Enron may conflict with their duties as directors of
Azurix. In addition, other conflicts of interest exist and may arise in the
future as a result of the extensive relationships between Enron and
                                       94
<PAGE>   100
 
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."
 
AGREEMENT REGARDING BUSINESS OPPORTUNITIES AND RELATED MATTERS
 
   
     Enron and Azurix have entered into an agreement that limits the scope of
Azurix's business and provides that Enron and its affiliates may engage in
water-related businesses, even if those businesses have a competitive impact on
Azurix. In general, Enron is permitted to engage in any business whatsoever,
including water, wastewater and other businesses competing with Azurix, and may
compete in public tenders against Azurix, provided the business is conducted and
opportunities are identified and developed through Enron's own personnel and not
through Azurix. If an opportunity in the water industry is presented to a person
who is an officer or director of both Enron and Azurix, the opportunity must
first be offered to Azurix, unless water constitutes a minority of the fair
market value of the opportunity, as determined by that officer or director in
good faith based on information available at the time.
    
 
   
     In the agreement, Azurix acknowledges that Enron has fiduciary and
contractual obligations to other persons and entities under existing agreements
and relationships and has agreed that, in the event of a conflict between the
duties of Enron under the agreement and the duties of Enron to third parties
under agreements or relationships that exist on the date of execution of the
agreement, Enron will be entitled to perform its duties to such third parties
without any liability to Azurix.
    
 
   
     The agreement provides that any standard of care, any duty of loyalty and
any other duty imposed by the agreement or under Delaware law or any other
applicable law, rule or regulation shall be modified, waived or limited as
required in order to permit Enron to act under the agreement and to make any
decision pursuant to the authority prescribed in the agreement so long as such
action is reasonably believed by Enron to be in, or not inconsistent with, the
agreement or the interests of Azurix. Azurix has agreed to indemnify Enron and
its officers, directors and employees against any claim that Enron's pursuit of
any water business was a breach of any duty owed by Enron to Azurix, provided
Enron has followed the rules described above.
    
 
   
     Azurix's purpose clause permits it to engage in the businesses generally
identified in this prospectus, activities incidental to those businesses, and
such other businesses as Enron may approve in its sole discretion. Azurix has
agreed not to amend its certificate of incorporation to expand its purpose
clause without Enron's prior written consent.
    
 
   
     The agreement restricts Enron and Azurix from taking action that might
cause either of them to violate any law or that would require either of them to
register as a public utility holding company under the Public Utility Holding
Company Act of 1935.
    
 
   
     The agreement states that whenever a potential conflict of interest exists
or arises between Enron and Azurix, any resolution or course of action in
respect of such conflict of interest shall be permitted and deemed approved, and
will not constitute a breach of any duty stated or implied by law or equity, if
the resolution or course of action is authorized by the agreement or, by
operation of the agreement, is deemed to be fair and reasonable to Azurix. The
agreement states that any conflict of interest and any resolution of such
conflict of interest shall be conclusively deemed fair and reasonable to Azurix
if such conflict of interest or resolution is:
    
 
     - Approved by special approval (the approval by a majority of the directors
       of Azurix not associated with Enron)
 
     - On terms no less favorable to Azurix than those generally being provided
       to or available from unrelated third parties
 
   
     - Fair to Azurix, taking into account the totality of the relationships
       between the parties involved, including other transactions that may be
       particularly favorable or advantageous to Azurix
    
 
                                       95
<PAGE>   101
 
     Enron may adopt a resolution or course of action that has not received
special approval. Enron and any person voting in connection with a special
approval will be authorized in connection with its determination of what is
"fair and reasonable" to Azurix and in connection with its resolution of any
conflict of interest to consider:
 
     - The relative interests of any party to such conflict, agreement,
       transaction or situation and the benefits and burdens relating to such
       interest
 
     - Any customary or accepted industry practices and any customary or
       historical dealings with a particular person
 
     - Any applicable generally accepted accounting or engineering practices or
       principles
 
     - Such additional factors as such person determines in its sole discretion
       to be relevant, reasonable or appropriate under the circumstances
 
     In the absence of bad faith by Enron, the resolution, action or terms so
made, taken or provided by Enron with respect to such matter shall not
constitute a breach of the agreement or a breach of any standard of care, any
duty of loyalty or any other duty imposed by the agreement or under Delaware law
or any other law, rule or regulation.
 
   
     Disputes under the agreement are to be resolved through arbitration. The
agreement will continue indefinitely, except that it will expire on the first
date on which both of the following occur:
    
 
   
     - Enron and its affiliates do not individually or collectively, directly or
       indirectly, own or have the power to vote at least one-third of the
       shares of Azurix ordinarily entitled to vote for the election of
       directors, and
    
 
   
     - Fewer than one-third of the directors of Azurix are persons who are
       employees, officers or directors of Enron or of any affiliate of Enron.
    
 
   
     The mutual covenants and agreements in the agreement will be the
consideration given by each party to the other in support of the agreement. In
addition, the agreement states that Enron's investment in Atlantic Water Trust
was predicated on the execution and delivery of an agreement containing
substantially the terms set forth in the agreement.
    
 
SERVICES AGREEMENT
 
   
     Effective May 1, 1999, we entered into an agreement with Enron pursuant to
which Enron provides various corporate staff and support services to us. These
services include information technology, office space, building maintenance,
security and other office services as well as employee development, training and
maintenance of compensation and other benefits programs. We also may utilize
Enron's regulatory affairs, marketing affairs, treasury and risk assessment and
control departments. In addition, Azurix may continue to participate in Enron's
corporate insurance program. The agreement provides that we may use the
international offices of Enron and its affiliates for projects, subject to
mutual agreement with Enron or its affiliates on a project-by-project basis. We
intend to enter into a related sublease with Enron providing for the use of
office space in Houston, Texas. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Recent Developments."
    
 
CREDIT AGREEMENT
 
   
     Effective May 1, 1999, we entered into a credit agreement with Enron,
whereby Enron will provide funds to us for general, administrative and operating
expenses. The credit agreement matures December 15, 2001 or 90 days following
the date that Enron or its affiliates do not own or have the power to vote at
least one-third of our capital stock ordinarily entitled to vote for the
election of directors and fewer than one-third of our directors are officers,
directors or employees of Enron or its affiliates. The total commitment under
the credit agreement will be $180 million. Advances under the facility will bear
interest
    
 
                                       96
<PAGE>   102
 
   
at the federal funds rate plus 1.50%. Amounts borrowed under the credit
agreement may be prepaid, in full or in part, at any time during the term of the
credit agreement. Amounts prepaid may be re-borrowed during the term of the
credit agreement. The principal amount outstanding under the credit agreement
will be limited to no more than:
    
 
     - $60 million at any time during calendar year 1999
 
     - $120 million at any time during calendar year 2000
 
   
     - $180 million at any time during calendar year 2001
    
 
   
     No further amounts may be borrowed, and all outstanding amounts must be
repaid within 90 days after the first date on which both of the following occur:
    
 
   
     - Enron and its affiliates do not individually or collectively, directly or
       indirectly, own or have the power to vote at least one-third of the
       capital stock of Azurix ordinarily entitled to vote for the election of
       directors, and
    
 
   
     - Fewer than one-third of the directors of Azurix are persons who are
       employees, officers or directors of Enron or of any affiliate of Enron.
    
 
   
     As of May 21, 1999, no amounts were outstanding under this credit
agreement.
    
 
   
LICENSE AGREEMENT
    
 
   
     Enron has licensed 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, until the first date on which both of the following
occur:
    
 
   
     - Enron and its affiliates do not individually or collectively, directly or
       indirectly, own or have the power to vote at least one-third of the
       shares of Azurix ordinarily entitled to vote for the election of
       directors, and
    
 
   
     - Fewer than one-third of the directors of Azurix are persons who are
       employees, officers or directors of Enron or of any affiliate of Enron.
    
 
   
     The license is royalty free, although Azurix bears costs associated with
its use under a related cost sharing agreement. The license agreement is for a
term of one year, and renews automatically and repetitively for similar terms,
unless terminated by either party upon 30 days' notice or earlier upon uncured
default. Following termination, Azurix must phase out use of existing materials
within 90 days. The cost sharing agreement provides for a sharing of Enron's
costs incurred to develop, maintain, enhance, promote or defend the licensed
trademarks. Our share of such costs will be pro rata based on our earnings
before interest and taxes. We do not anticipate that our share of such costs
will be material.
    
 
REGISTRATION RIGHTS AGREEMENT
 
   
     We have entered into an agreement with Atlantic Water Trust, which allows
Atlantic Water Trust to request us to register 80,500,000 shares of our common
stock owned by Atlantic Water Trust following the offering. Atlantic Water Trust
has the right to request one such registration during each 12-month period
following the date of the offering, plus one additional such registration. The
number of shares requested to be registered shall have an aggregate offering
price of at least $50 million. In addition, Atlantic Water Trust has the right,
which it may exercise at any time, to include such shares in any registration of
common stock made by us in the future. We have agreed to cooperate fully in
connection with any such registration and with any offering made under the
registration rights agreement and to pay all costs and expenses, other than
underwriting discounts and commissions, related to shares sold by Atlantic Water
Trust in connection with any such registration. The rights of Atlantic Water
Trust under the registration rights agreement are transferable by Atlantic Water
Trust. The agreement is for an indefinite term. See "Risk Factors -- Future
sales of our common stock may depress our stock price" and "Shares Eligible for
Future Sale."

ATLANTIC WATER TRUST
 
     In December 1998, Enron contributed Azurix to Atlantic Water Trust, a
Delaware business trust. The principal purpose of Atlantic Water Trust is to own
equity interests in Azurix and to own Bristol Water Trust, and to engage in
other transactions related to the sale of an interest in Atlantic Water Trust to
Marlin Water Trust. In connection with Enron's contribution of Azurix to
Atlantic Water Trust, Marlin Water Trust acquired for $1.149 billion a 50%
voting interest in Atlantic Water Trust, with Enron retaining a 50% voting
interest. Marlin Water Trust financed the acquisition of its interest in
Atlantic Water Trust by issuing senior notes for $1.024 billion that mature
December 15, 2001, and issuing trust certificates for a total of $125 million.
Currently, five institutional investors and their affiliates hold the trust
certificates of Marlin Water Trust.
 
   
     Of the $1.149 billion paid by Marlin Water Trust, $900 million was used to
repay a portion of the indebtedness incurred by Enron affiliates in connection
with the acquisition of Wessex. The remaining $249 million was deposited in an
account established by Bristol Water Trust, a wholly owned subsidiary of
Atlantic Water Trust. The funds in this account should generate sufficient
liquidity to fund distributions from Atlantic Water Trust to Marlin Water Trust
that will provide Marlin Water Trust with sufficient funds to service interest
on the senior notes and provide a yield to the trust certificate holders at
least through 2001. Azurix is not required to make any distributions to Atlantic
Water Trust, including any of its proceeds from the offering. Additionally,
neither Azurix nor any of its subsidiaries has guaranteed any obligations of
Marlin Water Trust and no assets of Azurix nor any of its subsidiaries are
pledged as security for the senior notes of Marlin.
    
 
   
     Enron is entitled, with respect to distributions resulting from the sale of
Azurix stock by Atlantic Water Trust, to receive the first $180 million of
distributions by Atlantic Water Trust. After the receipt of $180 million by
Enron, further distributions resulting from the sale of Azurix stock by Atlantic
Water Trust and other non-liquidating distributions are generally to be paid
first to Marlin Water Trust until Marlin Water Trust has received funds equal to
the amount then in its trust account, with the remainder to Enron. Liquidation
distributions by Atlantic Water Trust are generally to be paid to Enron and
Marlin Water Trust pro rata based on their then respective trust accounts.
    
 
   
     If Atlantic Water Trust fails by December 15, 2001 to make aggregate
distributions to Marlin Water Trust of amounts sufficient to repay the senior
notes of Marlin Water Trust, then Marlin Water Trust has the right to cause
Atlantic Water Trust to liquidate and sell its remaining shares of Azurix. In
order to prevent the liquidation of Atlantic Water Trust by Marlin Water Trust,
Enron has the right to contribute funds generated from Enron equity offerings to
Atlantic Water Trust to fund distributions to Marlin. In such event, Enron's
beneficial interest, but not voting interest, in Atlantic Water Trust would
increase and Marlin Water Trust's beneficial interest, but not voting interest,
in Atlantic Water Trust would decrease. Other actions, such as the refinancing
of the senior notes of Marlin Water Trust, might also be taken which could
eliminate the necessity of Atlantic Water Trust selling additional shares of
Azurix. However, Atlantic Water Trust may elect to sell, or be required to sell,
some or all of its remaining shares of Azurix in order to fund Marlin Water
Trust's obligations. The proceeds to Atlantic Water Trust from this initial
public offering are expected to be approximately $373.0 million, after deducting
underwriting discounts and commissions and estimated expenses and assuming no
exercise of the over-allotment option. After payment of underwriting discounts
and commissions and expenses, $180 million of these proceeds will be distributed
to Enron and the remainder will be distributed to Marlin Water Trust. The
proceeds distributed to Marlin Water Trust are expected to be used to redeem a
portion of the senior notes.
    
 
   
     Marlin Water Trust, or the trustee under its senior notes indenture, may
cause the liquidation of Atlantic Water Trust prior to December 15, 2001 if
specific events occur and the senior notes are not repaid from other sources.
These events include: (1) defaults under certain of Azurix's, Enron's or Marlin
Water Trust's debt obligations or (2) a downgrading of Enron senior debt to
below "Baa3" by Moody's Investors Service, Inc., "BBB-" by Standard & Poor's
Ratings Services or "BBB-" by Duff & Phelps Credit Rating Co. and a decline in
Enron's common stock price below $37.84. The last sale price of Enron common
stock, as reported by the New York Stock Exchange, on May 21, 1999 was $74.0625.

<PAGE>   105
 
     Each of Marlin Water Trust and Enron has the right and power at all times
to appoint up to 50% of the members of the board of directors of Atlantic Water
Trust. Marlin Water Trust's certificateholders are entitled to exercise Marlin
Water Trust's appointment rights. If the Marlin Water Trust certificateholders
defer exercising their appointment rights, Enron has the right to appoint such
members, but Marlin Water Trust has the right, at any time, without cause, to
remove any such members. To date, Enron has appointed all of the directors of
Atlantic Water Trust.
 
   
     Following the offering, as long as Atlantic Water Trust owns a majority of
our outstanding voting 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 voting stock held by persons
other than Atlantic Water Trust, Enron and its affiliates. Furthermore, Marlin
Water Trust, with the consent of the holders of a majority of our outstanding
voting 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. In each case, Marlin Water Trust's right to
designate directors shall be reduced by the number of directors that may be
elected by preferred stock entitled to elect directors as a class. 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.

<PAGE>   106
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of Azurix consists of 500,000,000 shares of
common stock, par value $0.01 per share, and 50,000,000 shares of preferred
stock, par value $0.01 per share. Prior to the offering, 100,000,000 shares of
common stock were outstanding. No shares of preferred stock have been issued.
 
   
     The following summarizes the material provisions of our capital stock and
important provisions of our certificate of incorporation and bylaws. This
summary is qualified by our certificate of incorporation and bylaws, copies of
which have been filed as exhibits to the registration statement of which this
prospectus is a part and by the provisions of applicable law.
    
 
COMMON STOCK
 
   
     Following the offering, 117,100,000 shares of common stock will be issued
and outstanding. Holders of common stock are entitled to one vote per share on
all matters to be voted upon by the stockholders. Because holders of common
stock do not have cumulative voting rights, the holders of a majority of the
shares of common stock can elect all of the members of the board of directors
standing for election. Subject to preferences of any preferred stock that may be
issued in the future, the holders of common stock are entitled to receive such
dividends as may be declared by the board of directors. The common stock is
entitled to receive pro rata all of the assets of Azurix available for
distribution to its stockholders. There are no redemption or sinking fund
provisions applicable to the common stock. All outstanding shares of common
stock are fully paid and non-assessable.
    
 
PREFERRED STOCK
 
     Subject to the provisions of the certificate of incorporation and
limitations prescribed by law, the board of directors has the authority to issue
up to 50,000,000 shares of preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions thereof, including dividend
rights, dividend rates, conversion rates, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
any series or the designation of such series, which may be superior to those of
the common stock, without further vote or action by the stockholders. There will
be no shares of preferred stock outstanding upon the closing of the offering and
Azurix has no present plans to issue any preferred stock.
 
     One of the effects of undesignated preferred stock may be to enable the
board of directors to render more difficult or to discourage an attempt to
obtain control of Azurix by means of a tender offer, proxy contest, merger or
otherwise, and thereby to protect the continuity of Azurix's management. The
issuance of shares of the preferred stock pursuant to the board of directors'
authority described above may adversely affect the rights of the holders of
common stock. For example, preferred stock issued by Azurix may rank prior to
the common stock as to dividend rights, liquidation preference or both, may have
full or limited voting rights and may be convertible into shares of common
stock. Accordingly, the issuance of shares of preferred stock may discourage
bids for the common stock or may otherwise adversely affect the market price of
the common stock.
 
DESCRIPTION OF PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS
 
  CLASSIFIED BOARD OF DIRECTORS AND LIMITATIONS ON REMOVAL OF DIRECTORS
 
   
     Our Board of Directors is divided into three classes. The directors of each
class are elected for three-year terms, with the terms of the three classes
staggered so that directors from a single class are elected at each annual
meeting of the stockholders. Until such time, called the "Trigger Date," as
neither Atlantic Water Trust nor Enron together with its subsidiaries owns a
majority of the outstanding voting stock of Azurix, the holders of a majority of
our outstanding voting stock may remove a director with or without cause. On and
after the Trigger Date, stockholders may remove a director only for cause and to
do so, at least 66 2/3% of the voting power of the outstanding shares of common
stock must vote for removal. The
    
 
                                       101
<PAGE>   107
 
   
Board of Directors, not the stockholders, will have the right to appoint persons
to fill vacancies on the Board of Directors.
    
 
  WRITTEN CONSENT OF STOCKHOLDERS
 
   
     Our certificate of incorporation provides that prior to the Trigger Date
any action required or permitted to be taken by our stockholders may be taken at
a duly called meeting of stockholders or by written consent of stockholders
owning the minimum number of shares required to approve such action. On and
after the Trigger Date, any action by our stockholders must be taken at an
annual or special meeting of stockholders. Special meetings of the stockholders
may be called only by the board of directors. This provision, which requires a
vote of at least 66 2/3% of the voting power of the outstanding shares of common
stock to be amended, could have the effect of deterring hostile takeovers or
delaying changes in control.
    
 
   
  ADVANCE NOTICE PROCEDURE FOR STOCKHOLDER PROPOSALS
    
 
     Our bylaws establish an advance notice procedure for the nomination of
candidates for election as directors as well as for stockholder proposals to be
considered at annual meetings of stockholders. In general, notice of intent to
nominate a director must be delivered to or mailed and received at our principal
executive offices as follows:
 
     - With respect to an election to be held at the annual meeting of
       stockholders, 120 days prior to the anniversary date of the proxy
       statement for the immediately preceding annual meeting of stockholders.
 
     - With respect to an election to be held at a special meeting of
       stockholders for the election of directors, not later than the close of
       business of the 10th day following the day on which such notice of the
       date of the meeting was mailed or public disclosure of the date of the
       meeting was made, whichever first occurs, and must contain specified
       information concerning the person to be nominated.
 
   
     Notice of stockholders' intent to raise business at an annual meeting must
be delivered to or mailed and received at our principal executive offices not
less than 120 days prior to the anniversary date of the proxy statement for the
preceding annual meeting of stockholders. These procedures may operate to limit
the ability of stockholders to bring business before a stockholders meeting,
including with respect to the nomination of directors of considering any
transaction that could result in a change in 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 as follows:
 
     - For any breach of the director's duty of loyalty to Azurix or its
       stockholders
 
     - For acts or omissions not in good faith or which involve intentional
       misconduct or knowing violation of laws
 
     - For unlawful payment of a dividend or unlawful stock purchase or stock
       redemption
 
     - For any transaction from which the director derived an improper personal
       benefit
 
     The effect of these provisions is to eliminate the rights of Azurix and its
stockholders, through stockholders' derivative suits on behalf of Azurix, to
recover monetary damages against a director for breach of fiduciary duty as a
director, including breaches resulting from grossly negligent behavior, except
in the situations described above. These provisions will not change after the
Trigger Date.

  BUSINESS COMBINATIONS UNDER DELAWARE LAW
    
 
   
     Under the terms of our certificate of incorporation and as permitted under
Delaware law we have elected not to be subject to Delaware's anti-takeover law.
This law provides that specified persons who, together with affiliates and
associates, own, 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. The law does not include interested
stockholders prior to the time our common stock is listed on the NYSE. This
includes Atlantic Water Trust and Enron. The law 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. With approval of our
stockholders, we could amend our Certificate of Incorporation in the future to
become subject to the anti-takeover law. This provision would then have an
anti-takeover effect with respect to transactions not approved in advance by our
Board of Directors, including discouraging takeover attempts that might result
in a premium over the market price for the shares of our common stock.
    
 
   
TRANSFER AGENT AND REGISTRAR
    
 
   
     The Transfer Agent and Registrar for the common stock is First Chicago
Trust Company of New York.
    
 
LISTING
 
   
     The common stock has been approved for listing on the New York Stock
Exchange under the symbol "AZX," subject to official notice of issuance.

                          DESCRIPTION OF INDEBTEDNESS
 
INDEBTEDNESS OF AZURIX
 
   
     Enron has funded on behalf of Azurix approximately $72 million to fund our
general, administrative and operating expenses, from our inception through May
21, 1999, in addition to capital expenditures. This includes $28.5 million
advanced to us by Enron to fund our acquisition of and loan to our acquisition
in Cancun. The amount due to Enron is non-interest bearing and has no maturity
date. We intend to use a portion of the net proceeds that we receive from the
offering to repay these amounts. See "Use of Proceeds."
    
 
   
     Effective May 1, 1999, we entered into a credit agreement with Enron,
whereby Enron will provide funds to us for general, administrative and operating
expenses. The credit agreement matures December 15, 2001 or 90 days following
the date that Enron or its affiliates do not own or have the power to vote at
least one-third of our capital stock ordinarily entitled to vote for the
election of directors and fewer than one-third of our directors are officers,
directors or employees of Enron or its affiliates. The total commitment under
the credit agreement will be $180 million. Advances under the facility will bear
interest at the federal funds rate plus 1.50%. Amounts borrowed under the
facility may be prepaid, in full or in part, at any time during the term of the
agreement. Amounts prepaid may be re-borrowed during the term of the facility.
The principal amount outstanding under the credit agreement will be limited to
no more than:
    
 
     - $60 million at any time during calendar year 1999
 
     - $120 million at any time during calendar year 2000
 
   
     - $180 million at any time during calendar year 2001
    
 
   
     No further amounts may be borrowed, and all outstanding amounts must be
repaid within 90 days after, the first date on which both of the following
occur:
    
 
   
     - Enron and its affiliates do not individually or collectively, directly or
       indirectly, own or have the power to vote at least one-third of our
       capital stock ordinarily entitled to vote for the election of directors,
       and
    
 
   
     - Fewer than one-third of the directors of Azurix are persons who are
       employees, officers or directors of Enron or of any affiliate of Enron.
    
 
   
     As of May 21, 1999, no amounts were outstanding under this credit
agreement.
    
 
   
INDEBTEDNESS OF AZURIX EUROPE
    
 
   
  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 entered into on May 10, 1999 with Chase Manhattan
Plc and Westdeutsche Landesbank Girozentrale, as arrangers, Westdeutsche
Landesbank Girozentrale, as facility agent, and Chase Manhattan Trustees
Limited, as security agent. The senior credit facility consists of a revolving
credit facility of L425 ($686.0) million. Amounts outstanding under the senior
credit facility bear interest at a rate based on the London interbank offered
rate, plus a margin. If loans outstanding at the time of a new loan are less
than 50% of the total commitment of the facility, then the margin applied to the
new loan will equal 0.75% per annum. If loans outstanding at the time of a new
loan are greater than or equal to 50% of the total commitment of the facility,
then the margin applied to the new loan will equal 1.00% per annum. Azurix
Europe will pay a commitment fee on the undrawn, uncancelled amount of the
facility at the rate of 0.375% per annum. As of May 21, 1999, L113.3 ($182.9)
million was outstanding under the facility. Of this amount, L66.3 ($107.0)
million was used primarily to fund the acquisition of Philip Utilities, L42.0
($67.8) million was used to refinance all of the amounts previously outstanding
under a former senior credit facility and approximately

L5.0 ($8.1) million was used to pay fees and expenses related to this facility.
The interest rate on the loan used to refinance existing debt of Azurix Europe
is 6.10% per annum payable August 13, 1999. The outstanding loan relating to the
Philip Utilities acquisition bears an interest rate of 5.70% per annum payable
July 14, 1999. As of May 21, 1999, a portion of the unused borrowing capacity
under this facility secures outstanding loan notes of L70.5 ($113.8) million
described below. Of the remaining borrowing capacity as of May 21, 1999, L67.5
($108.9) million is available to refinance any outstanding debt of Azurix Europe
and L173.7 ($280.4) million is available to make loans to affiliates of Azurix
Europe for the purpose of financing acquisitions of and investments in water and
wastewater assets and businesses. Loans to affiliates made under the facility
will be senior obligations, maturing on or before the maturity date of the
facility, and, if practicable at interest rates at least equal to the interest
rates on the facility. The loans will be guaranteed by Azurix in favor of Azurix
Europe. The affiliates will be direct or indirect wholly owned subsidiaries of
Azurix that have been created as special purpose vehicles. The facility is a
secured facility, and Azurix Europe has pledged all its existing assets,
including all the ordinary shares of Wessex. The facility is for a period of
three years from May 10, 1999.
    
 
   
     COVENANTS. Azurix Europe has agreed that it will not, and will ensure that
its subsidiaries will not, create or permit to exist any other security interest
on any of their assets, except in the ordinary course of business, to secure
project finance indebtedness or other security interests in an aggregate amount
not to exceed L35 ($56.5) million. Azurix Europe will not sell, transfer or
otherwise dispose of any of the ordinary shares of Wessex. Azurix Europe has
also agreed that it will not, and will ensure that its subsidiaries will not,
sell, transfer, grant or lease or otherwise dispose of all or any part of its
assets, except in the ordinary course of business or other disposals in an
aggregate amount not to exceed L35 ($56.5) million. Azurix Europe may 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 may conduct business
only as a holding company. Azurix Europe has agreed that it will not, and will
ensure that its subsidiaries will not, enter into any amalgamation, demerger,
merger or reconstruction. Azurix Europe has agreed that it will not, and will
ensure that its subsidiaries will not, acquire any assets or business or make
any investment if the assets, business or investment is substantial in relation
to Azurix Europe and its group, except in the ordinary course of business, as a
required capital expenditure or other acquisitions in an aggregate amount not to
exceed L10 ($16.1) million. Azurix Europe may not declare, recommend, make or
pay any dividend, distribution or payment to any of its shareholders and will
covenant to ensure that Wessex Water Services will dividend to Wessex the
maximum distribution permissible by the dividend policy, from time to time, of
Wessex Water Services and Wessex will dividend to Azurix Europe its maximum
distributable reserves from time to time. The facility also requires that the
aggregate borrowings plus liabilities for borrowings of Wessex that Azurix
Europe and its subsidiaries may have outstanding at any time do not exceed
L1,050 ($1,694.7) million. All excess cash flow of Azurix Europe (i.e., all cash
flow after deducting interest, taxes and operating expenses) will be paid into a
debt service reserve account. All excess cash flow will be applied to build up,
within six months of closing of the facility, an amount determined by the
security agent to be one year's gross interest payable under the facility. All
amounts credited to the debt service reserve account may be invested in cash and
cash equivalents with minimum credit ratings and, provided credit enhancement is
provided, may be lent by Azurix Europe to certain other entities, including
Azurix and Enron.
    
 
   
     FINANCIAL COVENANTS. Azurix Europe must maintain, and ensure Wessex
maintains, the following financial ratios on a quarterly and annual basis:
    
 
   
     - The ratio of consolidated EBITDA to consolidated net interest payable
       will be no less than, in the case of Azurix Europe, 2.25:1 and, in the
       case of Wessex, 2.5:1. At December 31, 1998, the ratios were 4.4:1 and
       12.1:1, respectively. At March 31, 1999, the ratios were 4.2:1 and 8.3:1,
       respectively.
    
 
   
     - The ratio of debt to total capitalization will not, as of each date on
       which it is tested, exceed, in the case of Azurix Europe, 50% and, in the

       million
 
     - Insolvency or bankruptcy of Azurix Europe or a material subsidiary
       occurring
 
     - Any attachment, or execution affecting any assets of Azurix Europe or a

       it is currently carried out without the license
 
   
     - Wessex's license or the rights or obligations under the license being

  ACQUISITION LOAN NOTES
 
   
     In connection with the acquisition of Wessex, Azurix Europe issued U.K.
pound denominated loan notes in a principal amount of L70.5 ($113.8) million to
Wessex shareholders in lieu of cash consideration for the ordinary shares of
Wessex. As of April 30, 1999, all L70.5 ($113.8) million principal amount of
acquisition loan notes were outstanding. The acquisition loan notes are
redeemable, at the option of the holder, semiannually beginning September 30,
1999 and ending on September 30, 2005 when the acquisition loan notes mature.
Interest on the acquisition loan notes accrues at the London interbank offered
rate and is payable semiannually. The interest rate for the period the
acquisition loan notes were outstanding during 1998 was 7.125%. At any time,
holders of acquisition loan notes can require a redemption of their notes at par
plus accrued interest in insolvency situations and if any principal or interest
payment is not paid within 30 days of its due date.

INDEBTEDNESS OF WESSEX
 
  BANK FACILITIES
 
   
     Wessex Water Services is a borrower under credit facilities with three
major banks that provide an aggregate of L75 ($121.1) million of availability
for general corporate purposes. As of April 30, 1999, L75 ($121.1) million was
outstanding under these credit facilities. These credit facilities were entered
into on April 1, 1999 and mature on April 1, 2002. Loans under these credit
facilities accrue interest daily at the London interbank offered rate plus a
margin of 0.275% per annum. Each of these credit facilities requires Wessex
Water Services to pay an annual commitment fee equal to 0.15% of the available
amount of the facility.
    
 
   
     Each of these facilities requires Wessex Water Services to maintain a ratio
in excess of 2:1 of earnings before interest received, interest costs,
exceptional charges and tax to interest costs less interest received. At
December 31, 1998 and March 31, 1999, the ratio was 5.1:1 and 5.1:1,
respectively. Wessex Water Services is currently in compliance with this
covenant.
    
 
     Each of these facilities provides that each of the following will be an
event of default:
 
     - Wessex Water Services failing to pay any amount due and payable under the
       facility on its due date
 
     - Wessex Water Services failing to comply with any other obligation under
       the facility, unless remedied within 30 days of the breach
 
   
     - Wessex Water Services providing the bank with materially inaccurate
       factual information
    
 
   
     - Wessex Water Services defaulting under any borrowing, where the
       outstanding amount exceeds L15 ($24.2) million, such that prepayment of
       such borrowing is required
    
 
   
     - The Secretary of State or the Director making an application for an order
       of the High Court directing that Wessex's business be managed by a person
       appointed by the High Court because Wessex materially breaches any
       principal duty or any enforcement order, Wessex is insolvent or the
       Secretary of State determines that Wessex should be liquidated
    
 
   
     - Wessex Water Services losing its license as the water and wastewater
       services provider over a portion of its geographical region such that it
       would lose 15% or more of its gross revenues
    
 
     - Wessex Water Services ceasing to be a subsidiary of Azurix
 
     In addition, as of April 30, 1999, L24 ($38.7) million was outstanding
under uncommitted credit facilities.
 
  EUROPEAN INVESTMENT BANK LOANS
 
   
     Wessex Water Services is a borrower under facilities provided by the
European Investment Bank for purposes of financing its capital investment
program. These facilities currently consist of two separate loans with an
aggregate principal balance outstanding as of April 30, 1999 of L41.3 ($66.6)
million, including the effect of currency swap contracts in place as follows:
    
 
   
     - A U.S. dollar denominated floating rate loan of $48.4 million repayable
       in full on October 1, 2001
    
 
   
     - A 25.0 billion Italian lire ($18.2 million) fixed rate loan repayable in
       ten semiannual installments through June 15, 2002
    
 
Wessex guarantees the obligations of Wessex Water Services under these
facilities.
 
                                       108
<PAGE>   114
 
   
     The U.S. dollar dominated loan bears interest at the London interbank
offered rate less 0.25% per annum. The Italian lire loan bears interest at 11.6%
per annum. Each of these facilities requires Wessex to maintain the following
financial covenants:
    
 
   
     - Consolidated net borrowings will not exceed 150% of consolidated net
       tangible worth; at December 31, 1998 and March 31, 1999, the ratio was
       39.9% and 42.9%, respectively
    
 
   
     - Operating profits will be at least 2.0x total interest expense on an
       annual basis; at December 31, 1998 and March 31, 1999, the ratio was 9.8x
       and 6.6x, respectively
    
 
   
     - Consolidated net tangible worth will be at least L400 million; at
       December 31, 1998 and March 31, 1999, consolidated net tangible worth was

     In each of these facilities, Wessex Water Services has agreed that it will
not carry on any business other than the business of providing water and
wastewater services in the area covered by its license and any ancillary
activity. An event of default will occur under each facility, allowing the bank
to require immediate payment, in the following instances:
 
     - If Wessex Water Services or Wessex is bankrupt or insolvent
 
     - If Wessex Water Services ceases to be a subsidiary of Wessex
 
     - If Wessex Water Services loses its license as the water and wastewater
       services provider over a portion of its geographical region such that it
       would lose 15% or more of its revenues

     Wessex Water Services is the lessee under a finance lease agreement with
Barclays Mercantile Business Finance Limited pursuant to which L59.7 ($96.4)
million of capital lease obligations (excluding interest on such obligations)
were outstanding as of April 30, 1999. Under the lease agreement, Wessex Water
Services is reimbursed by Barclays for the acquisition cost of machinery and
equipment acquired in connection with its capital expenditure program. Wessex
Water Services then makes periodic rental payments to Barclays. Payments are
made in installments payable semiannually through September 2002. Barclays has a
lien on the property that has been acquired in connection with the leases.
 
   
     Wessex guarantees the obligations of Wessex Water Services under the lease
agreement. As guarantor, Wessex has agreed to maintain the same financial
covenants as required by the European Investment Bank facilities described
above.
    
 
     The leasing of the equipment may be terminated at any time in the following
instances:
 
     - Wessex Water Services defaults in making any rental payment
 
     - Wessex Water Services or Wessex is bankrupt or insolvent

       Services
 
     - A material adverse change occurs to Wessex Water Services which

       lease agreement

  SENIOR UNSECURED BONDS
    
 
   
     On March 30, 1999, Wessex Water Services issued L300 ($484.2) million
principal amount of 10-year senior unsecured bonds bearing interest at 5.875%
per annum through its wholly owned subsidiary, Wessex Water Services Finance
Plc. Wessex Water Services has unconditionally and irrevocably guaranteed
payment of principal and interest of the bonds. All principal will be due on
March 30, 2009. Wessex Water Services used most of the proceeds from the sale of
the bonds to repay all outstanding amounts under its former bank credit
facilities as well as all outstanding amounts under uncommitted credit
facilities. The remaining proceeds will be used for general corporate purposes.
    
 
     The bonds will be redeemed by Wessex Water Services as follows:
 
     - On March 30, 2009 at their principal amount
 
   
     - At the option of Wessex Water Services, if it becomes obligated to pay
       additional amounts because of a change in law, at their principal amount
    
 
     - At the option of Wessex Water Services, in whole or in part, at the
       higher of the following:
 
   
        -- their principal amount
    
 
   
        -- a redemption price, which is calculated based on the published
           redemption yield for a reasonably equivalent U.K. Government issued
           security with similar maturity and coupon
    
 
     Bondholders have the right to require Wessex to buy back their bonds prior
to maturity at a price equal to the principal amount of the bond plus all
accrued but unpaid interest in the following instances:
 
     - Wessex's license as a water and wastewater company is terminated
 
     - Wessex Water Services Finance Plc ceases to be a subsidiary of Wessex
       Water Services
 
   
     - Material changes occur to the rights or benefits of Wessex's license and
       the rating on the bonds is downgraded below investment grade
    
 
   
     - Legislation is enacted which materially changes the duties or powers of
       the Secretary of State for the Environment or the Director General of
       Water Services and the rating on the bonds is downgraded below investment
       grade
    
 
     In addition, the bonds could become immediately due and payable if an event
of default occurs. These events include a cross-default by Wessex Water Services
or its subsidiaries under other debt instruments and events of insolvency.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of our common stock in the
public market could adversely affect the market price of our common stock. After
this offering is completed, the number of shares available for future sale into
the public markets will be subject to legal and contractual restrictions, some
of which are described below. The lapsing of these restrictions will permit
sales of substantial amounts of our common stock in the public market or could
create the perception that such sales could occur, which could adversely affect
the market price for our common stock. These factors could also make it more
difficult to raise funds through future offerings of common stock.
 
   
     After the offering, 117,100,000 shares of our common stock will be
outstanding. Of these shares, the 36,600,000 shares sold in the offering will be
freely transferable and may be sold without restriction or further registration
under the Securities Act, except for any shares acquired by an "affiliate" of
Azurix as defined in Rule 144 under the Securities Act. The remaining 80,500,000
shares of common stock outstanding and owned by Atlantic Water Trust will be
"restricted securities," as that term is defined in Rule 144, and may be sold in
the future without registration under the Securities Act to the extent permitted
by Rule 144, as described below, or any applicable exemption under the
Securities Act. In addition, shares owned by Atlantic Water Trust or its
transferee may be registered for sale under the Securities Act of 1933 under the
terms of its registration rights agreement with us. See "Transactions with
Enron, Atlantic Water Trust and Marlin Water Trust -- Registration Rights
Agreement" for more information regarding these registration rights.
    
 
RULE 144
 
   
     In general, under Rule 144 as currently in effect, a person, or persons
whose shares are aggregated, including an affiliate, who has beneficially owned
"restricted securities" for at least one year would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of:
    
 
   
     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately 1,171,000 shares immediately after the offering
    
 
   
     - The average weekly trading volume of the common stock on the New York
       Stock Exchange during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale with the SEC
    
 
     Sales under Rule 144 are also subject to certain other requirements
regarding the manner of sale, notice and availability of current public
information about Azurix.
 
   
     Since Atlantic Water Trust, the selling stockholder, is likely an
"affiliate" of us, subject to its exercise of registration rights described
under "Transactions with Enron, Atlantic Water Trust and Marlin Water Trust,"
the Rule 144 restrictions and requirements would be applicable to Atlantic Water
Trust's shares of Azurix for as long as the selling stockholder retains
affiliate status.
    
 
RULE 144(k)
 
   
     Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an "affiliate," is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.
    
 
LOCK-UP AGREEMENTS
 
   
     In connection with the offering, we, Enron and the selling stockholder have
agreed, with exceptions specified in the lock-up agreements, not to directly or
indirectly engage in the following activities for a
    
 
                                       111

       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of 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

       Similar Securities"
 
     As an exception to these restrictions, we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors -- Future sales of our common stock
may depress our stock price."
 
STOCK PLAN
 
   
     After the offering, we intend to file a registration statement covering the
sale of approximately 8.5 million shares of common stock reserved for issuance
under our stock plan.
    
 
   
     Upon expiration of the lock-up period, these shares may be sold at any time
subject to compliance with the volume limitations and other restrictions of Rule
144. Options to purchase approximately 8.5 million shares of common stock will
also be outstanding after the offering. Such options generally provide for
incremental vesting over a three to five year period. In addition, more options
may be granted in the future. See "Management -- Stock Plan."

                MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES
                  TO NON-UNITED STATES HOLDERS OF COMMON STOCK
 
     The following is a summary of material U.S. federal income and estate tax
consequences expected to result under current law from the purchase, ownership
and taxable disposition of common stock by non-U.S. holders of common stock. A
"non-U.S. holder" is any person or entity other than:
 
     - A citizen or resident of the United States
 
     - A corporation, partnership or other entity created or organized in or
       under the laws of the United States or any state thereof
 
     - An estate, the income of which is includable in gross income for U.S.
       federal income tax purposes regardless of its source
 
     - A trust whose administration is subject to the primary supervision of a
       United States court and which has one or more U.S. persons who have the
       authority to control all substantial decisions of the trust
 
     This summary does not address all of the U.S. federal income and estate tax
considerations that may be relevant to non-U.S. holders in light of their
particular circumstances or to non-U.S. holders that may be subject to special
treatment under United States federal income tax laws. This summary does not
discuss any aspect of state, local or foreign taxation. This summary is based on
current provisions of the Internal Revenue Code of 1986, as amended, Treasury
regulations, judicial opinions, published positions of the U.S. Internal Revenue
Service and other applicable authorities, all of which are subject to change,
possibly with retroactive effect. In this prospectus, the Internal Revenue Code
of 1986, as amended, is called the "Code." Prospective purchasers of common
stock are advised to consult their tax advisors regarding the U.S. federal,
state and local, and non-U.S. income and other tax consequences of acquiring,
holding and disposing of common stock.
 
DIVIDENDS
 
     Azurix does not currently anticipate paying any dividends. Any dividends
paid to a non-U.S. holder on shares of common stock will be subject to
withholding of U.S. federal income tax at a rate of 30%, unless a lower rate is
prescribed under an applicable tax treaty. U.S. federal income tax withholding
will not be required, however, if the dividends are effectively connected with
the conduct of a trade or business of the non-U.S. holder within the United
States or, in the case of an applicable tax treaty, are attributable to a U.S.
permanent establishment maintained by the non-U.S. holder. Dividends that are
effectively connected with the conduct of a trade or business within the United
States, or are attributable to a U.S. permanent establishment will be subject to
U.S. federal income tax on a net income basis which is not collected by
withholding provided the non-U.S. holder files the appropriate certification
with Azurix or its agent. Any dividends received by a foreign corporation that
are effectively connected with the conduct of a trade or business within the
United States may also be subject to a "branch profits tax" at a rate of 30% or
such lower rate as may be specified by an applicable tax treaty.
 
     For purposes of the withholding tax rules discussed above and for purposes
of determining the applicability of a tax treaty rate under current U.S.
Treasury Regulations, dividends paid to an address outside the United States
will be presumed to be paid to a resident of the country of address, unless the
payor has knowledge to the contrary. Under recently issued U.S. Treasury
Regulations (referred to as "final regulations") that are effective for payments
made after December 31, 1999, a non-U.S. holder of common stock who wishes to
claim the benefit of a tax treaty rate would be required to satisfy applicable
 
                                       113
<PAGE>   119
 
certification and other requirements. In addition, under the final regulations,
in the case of common stock held by a foreign partnership:
 
   
     - The certification requirement generally would be applied to the partners
       of the partnership
    
 
   
     - The partnership would be required to provide certain information,
       including a U.S. taxpayer identification number
    
 
     A non-U.S. holder of common stock that is eligible for a reduced rate of
U.S. federal income tax withholding pursuant to a tax treaty may obtain a refund
of any excess amounts currently withheld by filing an appropriate claim for
refund with the Internal Revenue Service.
 
SALE OR DISPOSITION OF COMMON STOCK
 
     A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of any gain recognized on the sale or other taxable disposition of
common stock so long as:
 
   
     - The gain is not effectively connected with the conduct of a trade or
       business of the non-U.S. holder within the United States nor under an
       applicable tax treaty, is attributable to a U.S. permanent establishment
       maintained by the non-U.S. holder
    
 
     - In the case of a non-U.S. holder who is an individual and holds the
       common stock as a capital asset, either:
 
   
        -- Such holder is not present in the United States for 183 or more days
           during the taxable year of the disposition
    
 
   
        -- Such holder does not have a "tax home" in the United States for U.S.
           federal income tax purposes nor does such holder maintain an office
           or other fixed place of business in the United States to which such
           gain is attributable
    
 
   
     - Such non-U.S. holder is not subject to tax pursuant to the provisions of
       U.S. federal income tax law applicable to certain U.S. expatriates
    
 
   
     - The common stock continues to be "regularly traded on an established
       securities market" for U.S. federal income tax purposes and the non-U.S.
       holder has not held, directly or indirectly, at any time during the
       five-year period ending on the date of disposition (or, if shorter, the
       non-U.S. holder's holding period) more than five percent of the
       outstanding common stock
    
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Azurix must report annually to the Internal Revenue Service and to each
non-U.S. holder the amount of dividends paid to, and the tax withheld with
respect to, each non-U.S. holder. These reporting requirements apply regardless
of whether withholding was reduced by an applicable tax treaty. Copies of these
information returns may also be made available under the provisions of a treaty
or information exchange agreement with the tax authorities in the country in
which the non-U.S. holder resides or is established. Under current law, U.S.
backup withholding tax, which is a withholding tax currently imposed at the rate
of 31% on certain payments to persons who fail to furnish the information
required under U.S. information reporting requirements, generally will not apply
to dividends paid on common stock to a non-U.S. holder at an address outside the
United States unless the payor has knowledge that the payee is a U.S. person.
However, under the final regulations, dividends paid on common stock after
December 31, 1999 may be subject to backup withholding unless applicable
certification requirements are satisfied.
 
     Payment of the proceeds from a sale of common stock to or through a U.S.
office of a broker will be subject to information reporting and backup
withholding unless the owner certifies as to its status as a non-U.S. holder
under penalties of perjury or otherwise establishes an exemption. Payment of the
proceeds from a sale of common stock to or through a non-U.S. office of a broker
generally will not be subject to information reporting or backup withholding.
However, if such broker is a U.S. person, a "controlled foreign corporation" or
a foreign person that derives 50% or more of its gross income from the conduct
of
                                       114
<PAGE>   120
 
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 includable 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.

</TABLE>
    
 
   
     Azurix, the selling stockholder and Enron have also entered into an
international purchase agreement with the international managers outside the
United States and Canada for whom Merrill Lynch International, Credit Suisse
First Boston (Europe) Limited, Donaldson, Lufkin & Jenrette International,
PaineWebber International (U.K.) Ltd., ABN AMRO Rothschild and HSBC Investment
Banking are acting as lead managers. Under the international purchase agreement,
and concurrently with the sale of 29,280,000 shares of common stock to the U.S.
underwriters under the U.S. purchase agreement, Azurix and the selling
stockholder have agreed to sell to the international managers, and the
international managers have agreed to purchase from Azurix and the selling
stockholder, an aggregate of 7,320,000 shares of common stock. The initial
public offering price per share and the total underwriting discount per share of
common stock are identical under the U.S. purchase agreement and the
international purchase agreement.
    
 
     In the U.S. purchase agreement and the international purchase agreement,
the U.S. underwriters and the international managers, respectively, have agreed,
under the terms of those agreements, to purchase all of the shares of common
stock being sold under those agreements if any of the shares of our common stock
being sold under those agreements are purchased. In the event of a default by an
underwriter, the U.S. purchase agreement and the international purchase
agreement provide that, in some circumstances, the purchase commitments of
nondefaulting underwriters may be increased or the purchase agreements may be
terminated. The closings for the sale of shares of our common stock to the U.S.
underwriters and the international managers are conditioned upon one another.
 
                                       116
<PAGE>   122
 
     Azurix and Enron have agreed to indemnify the U.S. underwriters and the
international managers against some liabilities, including some liabilities
under the Securities Act, or to contribute to payments the U.S. underwriters and
the international managers may be required to make in respect of those
liabilities.
 
     The shares of common stock are being offered by the underwriters, subject
to prior sale, when, as and if issued to and accepted by them, subject to
approval of legal matters by counsel for the underwriters and other conditions.
The underwriters reserve the right to withdraw, cancel or modify offers and to
reject orders in whole or in part.
 
COMMISSIONS AND DISCOUNTS
 
     The U.S. representatives have advised Azurix and the selling stockholder
that the U.S. underwriters propose initially to offer the shares of our common
stock to the public at the initial public offering price set forth on the cover
page of this prospectus, and to certain dealers at such price less a concession
not in excess of $     per share of common stock. The U.S. underwriters may
allow, and such dealers may reallow, a discount not in excess of $     per share
of common stock to certain other dealers. After the initial public offering, the
public offering price, concession and discount may be changed.
 
   
     The following table shows the per share and total public offering price,
the underwriting discount to be paid by Azurix and the selling stockholder to
the U.S. underwriters and the international managers and the proceeds before
expenses to Azurix and the selling stockholder. This information is presented
assuming either no exercise or full exercise by the U.S. underwriters and the
international managers of their over-allotment option.

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 4,392,000 additional shares of our common stock at the initial
public offering price set forth on the cover page of this prospectus, less the
underwriting discount. The U.S. underwriters may exercise this option solely to
cover over-allotments, if any, made on the sale of our common stock offered
hereby. To the extent that the U.S. underwriters exercise this option,
    
 
                                       117
<PAGE>   123
 
   
each U.S. underwriter will be obligated, subject to conditions specified in the
purchase agreement, 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 1,098,000 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 3,660,000 of the shares offered hereby to be sold
to some of our directors, officers and employees who have expressed an interest
in purchasing our common stock. 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 that 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, Enron and the selling stockholder have agreed, with exceptions
specified in the lock-up agreements, not to directly or indirectly engage in the
following activities for a period of 180 days after the date of this prospectus
without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith
Incorporated:
    
 
     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of our common stock or securities convertible into or
       exchangeable or exercisable for or repayable with our common stock,
       whether now owned or later acquired by the person executing the agreement
       or with respect to which the person executing the agreement later
       acquires the power of disposition, or file a registration statement under
       the Securities Act relating to any shares of our common stock
 
     - Enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of our common stock whether
       any such swap or transaction is to be settled by delivery of our common
       stock or other securities, in cash or otherwise, see "Shares Eligible for
       Future Sale"
 
     As an exception to these restrictions, we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors--Future sales of our common stock may
depress our stock price."
 
NEW YORK STOCK EXCHANGE LISTING
 
   
     The common stock has been approved for listing on the New York Stock
Exchange under the symbol "AZX," subject to official notice of issuance. To meet
the requirements for listing of our common stock on that exchange, the
underwriters have undertaken to sell lots of 100 or more shares to a minimum of
2,000 beneficial owners.
    
 
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations among
Azurix, the selling stockholder, Enron, the
 
                                       118
<PAGE>   124
 
U.S. representatives and the lead managers. The factors considered in
determining the initial public offering price, in addition to prevailing market
conditions, are the valuation multiples of publicly traded companies that the
U.S. representatives and the lead managers believe to be comparable to us,
including adjusted market value to EBITDA multiples, price to book value
multiples and price to earnings multiples, certain of our financial information,
the history of, and the prospects for, our company and the industry in which we
compete, an assessment of our management, our past and present operations, the
prospects for and timing of our future revenues, the present state of our
development, and the above factors in relation to market values and various
valuation measures of other companies engaged in activities similar to ours.
There can be no assurance that an active trading market will develop for our
common stock or that the common stock will trade in the public market subsequent
to this offering at or above the initial public offering price.
 
     The underwriters do not expect sales of our common stock to any accounts
over which they exercise discretionary authority to exceed 5% of the number of
shares being offered in this offering.
 
PRICE STABILIZATION AND SHORT POSITIONS
 
     Until the distribution of our common stock is completed, rules of the SEC
may limit the ability of the underwriters and selling group members to bid for
and purchase our common stock. As an exception to these rules, the U.S.
representatives and the lead managers are permitted to engage in certain
transactions that stabilize the price of our common stock. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of our common stock.
 
     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the U.S.
representatives and the lead managers may reduce that short position by
purchasing our common stock in the open market. The U.S. representatives and the
lead managers may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.
 
PENALTY BIDS
 
     The U.S. representatives and the lead managers may also impose a penalty
bid on underwriters and selling group members. This means that if the U.S.
representatives or the lead managers purchase shares of our common stock in the
open market to reduce the underwriters' short position or to stabilize the price
of our common stock, they may reclaim the amount of the selling concession from
the underwriters and selling group members who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
   
     None of Azurix, the selling stockholder or any of the underwriters makes
any representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of our common stock.
In addition, none of Azurix, the selling stockholder or any of the underwriters
makes any representation that the U.S. representatives or the lead managers will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
    
 
OTHER RELATIONSHIPS
 
     Some of the underwriters and their affiliates engage in transactions with,
and perform services for, our company, Enron and Enron's affiliates in the
ordinary course of business and have engaged, and may in the future engage, in
commercial banking and investment banking transactions and services with our
company, Enron and Enron's affiliates, for which they have received customary
compensation.
 
   
     We have engaged Merrill Lynch & Co. to act as our financial advisor in

                   UNAUDITED CONDENSED CONSOLIDATED PRO FORMA
                             FINANCIAL INFORMATION
 
   
     The following unaudited condensed consolidated pro forma statements of
income for the year ended December 31, 1998, and the three months ended March
31, 1999, give effect to the October 2, 1998 acquisition of Wessex by Azurix,
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, and Azurix's initial public offering of its stock, as though
each occurred on January 1, 1998. The unaudited condensed consolidated pro forma
balance sheet at March 31, 1999 gives effect to the offering as though such
offering occurred on March 31, 1999. The unaudited condensed consolidated pro
forma statements of income do not include the results of operations from
Azurix's investment in Obras Sanitarias Mendoza S.A. prior to the date it was
acquired, and do not include any pro forma or historical effects from Azurix's
investment in a water concession for the city of Cancun, Mexico prior to the
date it was acquired in 1999 or the acquisition of Philip Utilities Management
Corporation in May 1999. The unaudited condensed consolidated pro forma balance
sheet does not include any pro forma effect from Azurix's acquisition of Philip
Utilities.
    
 
   
     The unaudited condensed consolidated pro forma statements of income and
balance sheet have been prepared based upon the Azurix and Wessex consolidated
statements of income and balance sheet included elsewhere in this prospectus and
have been prepared based upon available information and assumptions that the
management of Azurix believes are reasonable. The unaudited condensed
consolidated pro forma statements of income are for informational purposes only,
and do not purport to represent what Azurix's actual results of operations would
have been had the Wessex acquisition, 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, and the offering,
occurred on January 1, 1998. The unaudited pro forma balance sheet is for
informational purposes only, and does not purport to represent Azurix's actual
financial position had the offering occurred on March 31, 1999. In addition, the
unaudited condensed consolidated pro forma financial statements are not
necessarily indicative of future results of operations or financial position 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
   
                              FINANCIAL STATEMENTS
    
 
   
     The following pro forma adjustments give effect to the Wessex acquisition,
and the related redemption of the preference shares of Wessex, sale of its
interest in Wessex Waste Management Ltd, a joint venture with Waste Management
International Plc, and the offering, as though each occurred on January 1, 1998
for income statement purposes, and give effect to the offering, as though it
occurred on March 31, 1999 for balance sheet purposes. The historical results of
Wessex for the period prior to the Wessex acquisition were derived by combining
the Wessex historical audited results for the period April 1, 1998 to October 2,
1998 and the Wessex historical audited results for the year ended March 31,
1998, less the historical unaudited results for the nine months ended December
31, 1997. The unaudited condensed consolidated pro forma statement of income
includes the 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 effects from Azurix's $13.5 million investment in a water
concession for the city of Cancun, Mexico prior to the date it was acquired in
March 1999 or the acquisition of Philip Utilities in May 1999.
    
 
   
     The cost of the Wessex acquisition, including transaction costs, was $2.4
billion. The pro forma adjustments are based on a preliminary purchase price
allocation because Azurix is in the process of finalizing its assessment of the
related fair values. This preliminary purchase price allocation includes
tangible assets of $2.7 billion, goodwill of $0.9 billion, liabilities assumed
of $1.1 billion and redeemable preferred stock of $0.1 billion. Azurix does not
believe the final evaluation of these assessments will materially affect the
allocation of the purchase price.
    
 
   
     The historical results of operations for Azurix are for the period from
January 29, 1998 (date of inception) to December 31, 1998. However,
substantially all of Azurix's results of operations occurred during the fourth
quarter of 1998, subsequent to the Wessex acquisition.
    
 
   
     (a) To adjust Wessex historical general and administrative expense for
costs incurred by Wessex prior to the Wessex acquisition, but directly related
to the Wessex acquisition.
    
 
   
     (b) To adjust historical Wessex depreciation of tangible assets and
amortization of goodwill acquired in the Wessex acquisition for the period
during 1998 prior to the Wessex acquisition. The adjustment to depreciation and
amortization was based on a preliminary purchase price allocation. Goodwill is
being amortized over 40 years.
    
 
     (c) To adjust historical equity earnings from Wessex's historical results
to reflect the sale of its interest in Wessex Waste Management Ltd for $337.9
million.
 
     (d) To record the following:
 
   
          (1) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated loan notes issued to Wessex
     shareholders to finance the Wessex acquisition. The average balance
     outstanding was $116.4 million, adjusted for foreign currency exchange
     rates, and an average interest rate of 7.8% was assumed;
    
 
   
          (2) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated affiliate note payable used to finance
     the Wessex acquisition in the amount of $120.5 million, adjusted for
     average foreign currency exchange rates, at an assumed interest rate of
     6.25%;
    
 
   
          (3) Interest expense for the period January 1, 1998 to October 2, 1998
     on U.K. pounds sterling denominated funds borrowed under a five year bank
     credit facility used to finance the Wessex acquisition less a portion of
     the proceeds received from the sale of its interest in Wessex Waste
     Management Ltd that were used to paydown such borrowings. The average
     balance outstanding was $209.7 million, adjusted for foreign currency
     exchange rates, and an average interest rate of 8.2% was assumed;
    
 
                                       F-6
<PAGE>   133
 
          (4) Interest expense for the period January 1, 1998 to December 9,
     1998 on U.K. pounds sterling denominated funds borrowed to redeem Wessex's
     preference shares. The weighted average funds borrowed was $215.5 million,
     adjusted for foreign currency exchange rates, and an average interest rate
     of 8.1% was assumed.
 
     (e) To reflect the reduction in dividends related to the redemption of the
Wessex preference shares.
 
     (f) To record the tax impact of the pro forma adjustments described above
at the U.K. statutory rate of 31%, excluding non-deductible goodwill
amortization.
 
   
     (g) To reflect the reduction in interest expense due to the planned
repayment of a portion of the existing debt from the proceeds of the offering.
    
 
   
     (h) To reflect shares issued by Azurix in the offering.
    
 
   
     (i) To record the estimated net proceeds of $327.1 to Azurix from the
offering less $67.8 million of the proceeds used to paydown debt and $64.2
million of the proceeds used to repay funds advanced to Azurix by Enron as of
March 31, 1999. Azurix has drawn $182.9 million under its senior credit facility
as of May 21, 1999. Azurix intends to use $182.2 million of the net proceeds
from the offering along with available cash to repay this indebtedness.
Following the application of the net proceeds from the offering, $387.4 million
of borrowing capacity under the senior credit facility will be available to fund
future acquisitions. It is expected that $365.7 million of this facility, along
with $72.9 million of proceeds from the offering, will be used to fund the
$438.6 million acquisition of an interest in concessions in two regions of the
Province of Buenos Aires, Argentina.
    
 
   
     (j) To record the partial use of proceeds to Azurix from the offering to
repay funds advanced to Azurix by Enron.
    
 
   
     (k) To record the partial use of proceeds to Azurix from the offering to
paydown debt.
    
 
   
     (l) To reflect the offering of Azurix's stock. The number of shares assumed
to be offered by Azurix is 17.1 million. The assumed offering price per share is
$20.50 and the assumed underwriting discounts and expenses related to the shares
offered by Azurix are $23.5 million.

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

                                   UNAUDITED)
    
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS
 
   
     Azurix Corp. was formed by Enron Corp. on January 29, 1998. Azurix is
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, 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 (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. Wessex
and Obras Sanitarias Mendoza 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. This agreement was not binding until specific material conditions were
met, and these conditions were met subsequent to December 31, 1998. As a result,
the Cancun concession is not reflected in Azurix's 1998 financial statements.
The purchase price was $13.5 million and Azurix agreed to provide up to $25.0
million in debt financing. On February 25, 1999, Azurix funded $15.0 million of
debt financing to the Cancun concession. The Cancun concession acquisition
closed on March 24, 1999. The results of the Cancun concession acquisition are
reflected in the financial statements as of the acquisition closing date.
    
 
   
     Azurix 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.
    
 
   
INTERIM PRESENTATION (UNAUDITED)
    
 
   
     The accompanying consolidated interim financial statements and disclosures
are unaudited and have been prepared by Azurix in accordance with generally
accepted accounting principles and reflect all adjustments, consisting solely of
normal recurring adjustments, necessary for a fair presentation in all material
respects of the results for the interim period. The results of operations for
the three months ended March 31, 1999 are not necessarily indicative of results
to be expected for the full year. Interim financial statements for the period
January 29, 1998 to March 31, 1998 are not presented because Azurix did not have
any results of operations or cash flows during the period.
    
 
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. 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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
   
(INFORMATION PRESENTED HEREIN FOR THE PERIOD SUBSEQUENT TO DECEMBER 31, 1998 IS
                                   UNAUDITED)
    
 
REVENUE RECOGNITION
 
     Operating revenue represents income earned in the ordinary course of
business, excluding value added tax. Revenue for metered customers is recognized
based on actual usage and accrued based on the estimated amount of water sold
but not billed as of the balance sheet date. Revenue for non-metered customers,
who pay an annual fixed charge based on the rateable value of their property, is
recognized uniformly over the year.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
     Azurix utilizes derivative financial instrument contracts for non-trading
purposes to manage exposure to fluctuations in interest rates and foreign
currency exchange rates. Hedge accounting is utilized in non-trading activities
where there is a high correlation of price movements in the derivative and the
contract is designated as a hedge. In instances where the anticipated
correlation of price movements no longer exists, hedge accounting is terminated
and future changes in the value of the derivative financial instruments are
recognized as gains or losses to net income.
 
     Interest rate swaps involve the exchange of amounts based on a fixed
interest rate for amounts based on variable interest rates over the life of the
contract without an exchange of the notional amount upon which payments are
based. The difference to be received or paid is recognized in income over the
life of the contracts as adjustments to interest expense.
 
     Currency swap contracts are denominated in one foreign currency and are to
be repaid in another currency. These contracts are designated as hedges of firm
commitments to pay interest and principal on debt, which would otherwise expose
Azurix to foreign currency risk.
 
     The fair values of the swap contracts are not recognized in the financial
statements. The income and cash flow impact of financial instruments is
reflected as an adjustment of the hedged item. Gains and losses on terminations
of interest rate and currency swap contracts are deferred as an adjustment to
the carrying amount of the outstanding obligation and amortized as an adjustment
to interest expense related to the obligation over the remaining term of the
original contract life of the terminated swap contract. In the event of early
extinguishment of the obligation, any realized or unrealized gain or loss from
the swap would be recognized in net income at the time of extinguishment.
 
INCOME TAXES
 
   
     Azurix accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." Under the
asset and liability method of Statement of Financial Accounting Standards 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
 
   
     Statement of Financial Accounting Standards 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.
    
                                      F-15

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
   
(INFORMATION PRESENTED HEREIN FOR THE PERIOD SUBSEQUENT TO DECEMBER 31, 1998 IS
                                   UNAUDITED)
    
 
   
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. At March 31, 1999, Azurix had stock options outstanding to
purchase 7.8 million shares of its common stock (see Note 13). For the three
months ended March 31, 1999, these options were not dilutive to basic earnings
per share.
    
 
CASH EQUIVALENTS
 
     Azurix considers all highly liquid investments with original maturities of
three months or less to be cash equivalents.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is stated at cost. Cost of acquired property,
plant and equipment includes an allocation of the purchase price based on the
asset's fair market value. Cost of property, plant and equipment placed in
service includes direct charges for material, labor and services and indirect
charges related to construction, such as engineering, supervision, payroll taxes
and employee benefits. The October 1998 acquisition of Wessex represents
substantially all of the property, plant and equipment as of December 31, 1998
(see Note 2). Additions, replacements, modifications and enhancements to units
of property are capitalized. Major improvements to leasehold properties are
amortized over the shorter of the asset life or the life of the respective
lease. Repairs, maintenance and minor replacements are charged to operations and
maintenance expense as incurred. Interest capitalized is based on the average
value of construction work in progress at Azurix's average borrowing rate during
the period. The amount of interest capitalized during 1998 was approximately
$2.3 million.
 
     Azurix's infrastructure assets comprise a network of systems of mains and
sewers, impounding and pumped raw water storage reservoirs, dams, sludge
pipelines and infrastructure investigations and studies.
 
     The cost of property, plant and equipment is charged to depreciation using
the straight-line method over the estimated useful lives of the assets.
Depreciation is computed based on estimated useful lives as follows:

LONG-LIVED ASSETS
 
   
     In accordance with Statement of Financial Accounting Standards 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.

(INFORMATION PRESENTED HEREIN FOR THE PERIOD SUBSEQUENT TO DECEMBER 31, 1998 IS
                                   UNAUDITED)
    
 
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 some customers in advance of providing water and wastewater
services and classifies these amounts as "Deferred income" on the Consolidated
Balance Sheet until earned.
    
 
PENSION BENEFITS
 
     The pension plans maintained by Wessex (see Note 12) are of the defined
benefit type, and are valued by an independent actuary. Current service costs
for the plans are accrued in the period to which they relate. Prior service
costs and actuarial gains and losses, if any, relating to amendments to the
plans, are recognized on a basis designed to spread the costs over the remaining
average service lives of employees.
 
FOREIGN CURRENCY TRANSLATION
 
     The functional currency for Azurix's foreign operations is the applicable
local currency. The translation from the applicable foreign currencies to U.S.
dollars is performed for balance sheet accounts using the current exchange rates
in effect at the balance sheet date and for revenue and expense accounts, using
the weighted average exchange rate during the period or, where known or
determinable, at the rate on the date of the transaction for significant items.
The resulting translation adjustments are recorded in comprehensive income as a
component of stockholder's equity and are included in income only upon the sale
or liquidation of the underlying investments.
 
ENVIRONMENTAL COSTS
 
     Environmental expenditures that relate to current operations are expensed
as incurred. Expenditures providing a future benefit are capitalized as
appropriate. Remediation costs that relate to an existing condition caused by
past operations are accrued when it is probable that these costs will be
incurred and can be reasonably estimated.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
   
     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This statement establishes accounting and reporting
standards for derivative instruments, including 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 Statement
of Financial Accounting Standards No. 133 will have on its financial statements.
    
 
   
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 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. Statement of Position 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 Statement of Position 98-5 in 1998, the year
of Azurix's inception, and therefore there is no cumulative effect.
    
 
SEGMENT, GEOGRAPHIC AND QUARTERLY REPORTING
 
   
     The Financial Accounting Standards Board issued Statement of Financial
Accounting Standard 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 operated in one segment and were substantially located in one geographic
region. In addition, Azurix's operations began in the fourth quarter of 1998 and
therefore separate quarterly disclosures have been omitted.
    
 
   
NOTE 2 -- BUSINESS ACQUISITION
    
 
   
     On October 2, 1998, Azurix, through its indirect wholly owned subsidiary
Azurix Europe Ltd, 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

     These unaudited pro forma results of operations have been prepared for
illustrative purposes only and include adjustments in addition to the
pre-acquisition historical results of Wessex, such as additional amortization
expense as a result of goodwill, increased depreciation expense resulting from
allocation of fair market value to fixed assets acquired, increased interest
expense on acquisition debt and preference share redemption and the sale of
Wessex's interest in UK Waste (see Note 3). The unaudited pro forma financial
information is not necessarily indicative of the results of operations that
would have occurred had the Wessex acquisition occurred on the date indicated,
and should not be viewed as indicative of operations in future periods.
    
 
NOTE 3 -- SALE OF ACQUIRED EQUITY INVESTMENT
 
   
     On November 30, 1998, Azurix, sold its interest in Wessex Waste Management
Ltd, a joint venture with Waste Management International Plc that does business
as UK Waste, to Waste Management International 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.
    
 
     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 the London interbank
offered rate plus 0.18% and the London interbank offered rate 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. At December 31, 1998, Azurix intended to refinance the
$424.0 million of short-term bank borrowings with long-term debt. At December
31, 1998, Azurix had amounts available under the senior credit facility (see
Note 7) to refinance the short-term bank borrowings on a long-term basis and
accordingly, reclassified its short-term bank borrowings as long-term debt.
    
 
   
     On March 30, 1999, Azurix repaid all of its short-term bank borrowings
outstanding on that date with the proceeds from a bond offering that matures in
2009 (see Note 7).

     Azurix entered into a U.K. pounds sterling denominated senior secured bank
credit facility in August 1998, as amended. At December 31, 1998, the senior
credit facility 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 the
London interbank offered rate 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 (see
Note 2). The loan 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 or a commitment from Enron 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 the London interbank offered rate and is
payable semi-annually. The London interbank offered rate for the period the loan
notes were outstanding during 1998 was 7.125%.
    
 
   
     The European Investment Bank credit facilities consist of two separate
loans, one of which has a floating interest rate based on the London interbank
offered rate less 0.25%, and the other has a fixed interest rate of 11.6%. The
floating rate obligation, due October 2001, has an outstanding balance of $49.9
million at December 31, 1998 and is U.S. dollar denominated. The fixed rate
loan, denominated in Italian lire, has an outstanding balance of $18.8 million
at December 31, 1998 and is payable in semiannual installments through June
2002.

     Azurix issued U.K. pounds sterling denominated senior unsecured bonds on
March 30, 1999, with a face value of $484.2 million. The net proceeds were
primarily used to refinance the short-term bank borrowings that were outstanding
on that date. The senior unsecured bonds mature March 30, 2009 and bear interest
of 5.875% payable annually.
    
 
   
     The U.K. pounds sterling denominated capital lease obligation provides for
semi-annual payments. At December 31, 1998, future minimum lease payments total
$129.1 million, including $19.4 million representing interest. Currently, $158.3
million of historical cost and $21.5 million of related accumulated amortization
is recorded under a capital lease and included in property, plant and equipment.
    
 
   
     Each of these financing agreements contains restrictive covenants which
include limitations on borrowings, the maintenance of financial ratios such as
interest coverage, net worth and debt to equity and contracts to perform or
refrain from undertaking acts related to regulations of the industry. The
financing contracts include standard events of default, including non-payment,
cross-defaults and insolvency. Azurix is currently in compliance with these
covenants.
    
 
   
     At December 31, 1998, 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.
    
 
   
     At March 31, 1999, long-term borrowing and capital lease obligation
maturities over the next five years are $16.0 million during the remainder of
1999, $336.9 million in 2000, $82.1 million in 2001, $35.2 million in 2002 and
$19.6 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
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

     Azurix is exposed to 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. Advance Corporation Tax 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. Advance Corporation Tax
credit has an indefinite carryforward period. At December 31, 1998, Azurix has a
U.S. tax loss carryforward of approximately $14.7 million that will expire in
2018. Management believes that sufficient uncertainty exists regarding the
realizability of the U.S. loss carryforwards, such that a valuation allowance is
appropriate at December 31, 1998. At March 31, 1999, management believes that no
valuation allowance is necessary for U.S. losses generated in the first three
months of 1999 due to the expected future income resulting from finalizing water
projects and available tax planning strategies. All deferred tax assets will be
reassessed as future business activity occurs. At December 31, 1998, Azurix has
U.K. subsidiary company loss carryforwards of approximately $11.8 million that
can be carried forward for an indefinite period. However, due to restrictions on
the use of such loss carryforwards, the benefits have not been reflected in
Azurix's results of operations.
    
 
     U.S. and foreign income taxes have been provided for earnings of foreign

NON-CASH TRANSACTIONS
 
   
     During 1998, Azurix issued debt in the form of the loan notes in connection
with the Wessex acquisition (see Note 7). During 1998, Azurix received a capital
contribution from Enron of the outstanding stock of a subsidiary that holds an
interest in Obras Sanitarias Mendoza. 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 the London interbank offered rate 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. 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
in a manner beneficial to Enron and its stockholders. Similarly, the directors
and officers of Azurix have fiduciary duties to manage Azurix in a manner
beneficial to Azurix and its stockholders.
    
 
     Enron and Azurix propose to enter into an agreement that addresses the
scope of Azurix's business and it is anticipated that it will provide that
certain activities in which Enron and its affiliates may engage are permitted,
even if those activities have a competitive impact on Azurix. In general, it is
anticipated that Enron will be permitted to engage in any business whatsoever,
including water, wastewater and other businesses competing with Azurix, and may
compete in public tenders against Azurix, provided the business is conducted and
opportunities are identified and developed through Enron's own personnel and not
through Azurix. The agreement is expected to contain other provisions regarding
the activities to be performed by Azurix and Enron's involvement in those
activities.
 
     Enron provides office space (see Note 15) to Azurix and various services
such as computer hardware and software and support services such as risk
management, accounts payable, payroll and information technology services. Costs
are allocated to Azurix based upon usage, or where no direct method can be

efficiently applied due to administrative burden, upon factors such as
annualized payroll or employee headcount.
 
     Employees, other than Wessex employees, are covered by various employee
benefit plans of Enron such as retirement, stock option, medical, dental, life
insurance and other benefit plans. These costs are allocated to Azurix based
upon Enron's costs of administering and providing the benefit plans. During 1998
the expense recorded under the plan arrangements was approximately $1.4 million.
 
   
     During 1998, Enron advanced to Azurix $17.7 million related to office space
and other services provided by Enron and costs of benefit plans for 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 assets utilized in the
subsidiary's operations. The subsidiary was charged $0.1 million for the use of
those assets during the period Azurix owned Wessex.
    
 
BRISTOL WATER TRUST
 
   
     During 1998, Azurix entered into a U.K. pounds sterling denominated senior
loan agreement with Bristol Water Trust, as amended and restated, an affiliate
company wholly owned by Atlantic Water. The note accrues interest at 6.25% per
annum and is payable semi-annually, beginning June 1999. Under the note
agreement maturing December 2001, prepayment is allowed in whole or part at any
time. The principal balance outstanding at December 31, 1998 was $121.4 million.
Interest expense recorded for 1998 was $1.9 million.
    
 
NOTE 12 -- PENSION BENEFITS
 
     Wessex maintains three defined benefit pension plans that cover
substantially all of its employees. The assets are held in separate trustee
administered funds. The pension cost charged to the consolidated statement of
income has been determined on the advice of independent qualified actuaries and
is accrued over the service lives of the employees expected to be eligible to
receive such benefits.
 
     The following weighted average assumptions were used in determining the
funded status and pension charge for the period October 2, 1998 through December
31, 1998:

NOTE 13 -- STOCKHOLDER'S EQUITY
 
COMMON STOCK
 
   
     During 1998, Azurix issued 1,000 shares of $1.00 par value common stock. On
February 2, 1999, Azurix effected a 100,000-for-one stock split and restated the
par value to $0.01 that resulted in 100 million shares issued and outstanding.
Share and per share data for 1998 presented herein have been adjusted to give
effect to this split as if it had occurred on the date of inception of Azurix.

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 Obras
Sanitarias Mendoza. 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 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 stock incentive plan may not exceed 15%
of the total number of shares of common stock outstanding. Under the stock
incentive 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 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's subsidiaries at December 31, 1998 is approximately $1.5 billion.
    
 
NOTE 15 -- COMMITMENTS AND CONTINGENCIES
 
     Azurix leases office space from Enron under a lease obligating only Enron
and specific subsidiaries and affiliates (see Note 11). Azurix has no
contractual obligation under these office lease agreements but pays to Enron the
amount determined in the lease or the contract rate applied to square footage
occupied. Azurix accrued rent expense to Enron for office space totaling $0.3
million in 1998.
 
     Azurix leases property under various operating leases. Future minimum
operating lease payments as of December 31, 1998, in the aggregate and for each
of the five succeeding fiscal years, are as follows:

     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

regulatory controls. Some of these changes or decisions could have a material
adverse effect on our financial position and results of operations.
 
     A substantial portion of Azurix's revenues are subject to governmental
regulation of the rates that it may charge to its customers. The U.K. government
is currently conducting a periodic review of the price limits for water and
sewerage companies in England and Wales that is expected to result in new price
limits for the period from April 1, 2000 through 2005 that will be lower than
current price limits. Although we are unable to predict the precise outcome of
the current U.K. rate review, it is likely to significantly reduce Wessex's
revenues and earnings, but should not have a material adverse effect on Azurix's
financial position.
 
NOTE 16 -- EVENTS SUBSEQUENT TO THE DATE OF REPORT OF INDEPENDENT PUBLIC
ACCOUNTANTS (UNAUDITED)
 
     In March 1999, Azurix filed a registration statement with the Securities
and Exchange Commission for an underwritten initial public offering of shares of
common stock.
 
   
     Azurix entered into an agreement on March 25, 1999 to acquire 100% of the
stock of Canadian-based Philip Utilities Management Corporation for $106.3
million. Philip Utilities is a water and wastewater services company in the U.S.
and Canada that provides operations and management, engineering, residuals
management and underground infrastructure development services for municipal
water and wastewater facilities. The acquisition closed on May 18, 1999 and will
be reflected in Azurix's financial statements as of that date.
    
 
   
     On May 10, 1999, Azurix entered into a $686.0 million revolving credit
facility. On May 13, 1999, Azurix borrowed approximately $75.9 million, of which
approximately $67.8 million was used to repay all of the remaining indebtedness
outstanding on the former senior credit facility (see Note 7) and approximately
$8.1 million was used to pay fees and expenses related to this facility. On May
14, 1999, Azurix borrowed $107.0 million under this revolving credit facility
primarily to fund the purchase of Philip Utilities. A portion of the unused
borrowing capacity under this facility secures outstanding loan notes of $113.8
million (see Note 7). The facility bears interest at the London interbank
offered rate plus 0.75% to 1.0%, depending on the level of utilization of the
borrowing capacity. After funding the Philip Utilities acquisition, the
revolving credit facility has approximately $280.4 million of borrowing capacity
for acquisitions.
    
 
   
     Advances may be drawn in sterling, U.S. dollars and euros. The facility
bears interest at a rate of the London interbank offered rate plus 0.75% to
1.0%, depending on the level of utilization of the borrowing capacity. Azurix
incurs commitment fees of 0.375% on the unused borrowing capacity of this
facility. The facility terminates on May 10, 2002.
    
 
   
     This facility contains restrictive covenants which include limitations on
borrowings, the maintenance of financial ratios such as interest coverage and
debt to equity and contracts to perform or refrain from undertaking certain
acts. The facility includes standard events of default, including non-payment,
cross-defaults and insolvency. Azurix is currently in compliance with these
covenants.
    
 
   
     Effective May 1, 1999, Azurix signed an agreement with Enron pursuant to
which Enron will provide various corporate staff and support services to Azurix.
These services include information technology, office space, building
maintenance, security and other office services as well as employee development,
training and maintenance of compensation and other benefits programs. Azurix may
utilize Enron's regulatory affairs, marketing affairs, treasury and risk
assessment and control departments. In addition, Azurix may continue to
participate in Enron's corporate insurance program. The agreement provides that
Azurix may use the international offices of Enron and its affiliates for
projects, subject to mutual agreement with Enron

or its affiliates on a project-by-project basis. The agreement provides that
Azurix will reimburse Enron for direct charges related to the Enron services and
facilities that it utilizes. Azurix will also be allocated an amount for
overhead charges related to Enron corporate staff and support services which it
utilizes. This overhead charge will be allocated based upon factors such as
employee headcount, payroll and square footage. Azurix management believes the
allocation methods and costs are reasonable. Costs for services used under the
agreement are expected to be approximately $15 million annually. The agreement
is for an indefinite term, but either party may terminate the agreement on 180
days' notice. Azurix intends to enter into a related sublease with Enron
providing for the use of office space in Houston, Texas.
    
 
   
     Effective May 1, 1999, Azurix entered into a credit agreement with Enron,
whereby Enron will provide funds to Azurix for general, administrative and
operating expenses. The credit agreement terminates December 15, 2001 or 90 days
following the date that Enron or its affiliates do not own or have the power to
vote at least one-third of our capital stock ordinarily entitled to vote for the
election of directors and fewer than one-third of our directors are officers,
directors or employees of Enron or its affiliates. The total commitment under
the credit agreement will be $180 million. Advances under the credit agreement
will bear interest at the federal funds rate plus 1.50%. Amounts borrowed under
the credit agreement may be prepaid, in full or in part, at any time during the
term of the credit agreement.
    
 
   
     On May 18, 1999, authorities in the Province of Buenos Aires, Argentina,
notified Azurix that, subject to final confirmation, Azurix will be awarded an
interest in 30-year water and wastewater concessions in two regions of the
province, at an aggregate price of $438.6 million. Assuming this award is
formally confirmed, Azurix will acquire a 90% interest in the concession
companies and take control of the systems on June 18, 1999.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
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
Water Ltd) (predecessor company) (the "Company") and subsidiaries for the period
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. On
October 2, 1998, Wessex was purchased by Azurix Europe Ltd, a wholly owned
subsidiary of Azurix Corp. 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. The functional currency of
Wessex is pounds sterling. These accounts have been presented using U.S. dollars
as the reporting currency by translating the functional currency financial
statements using the current rate methodology described in the Statement of
Financial Accounting Standard 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 U.K. 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 U.K. 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, 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.
 
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 pounds sterling functional
currency financial statements to U.S. dollars were:

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

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

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
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

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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", and related interpretations in accounting for its
employee stock options. Under Accounting Principles Board Opinion No. 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 Financial Accounting Standards Board issued Statement of
Financial Accounting Standard 133 "Accounting for Derivative Instruments and
Hedging Activities," which establishes accounting and reporting standards for
derivative instruments and hedging activities. Statement of Financial Accounting
Standard 133 requires that an entity recognize all derivatives as either assets
or liabilities in the balance sheet at fair value. Statement of Financial
Accounting Standard 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. Wessex is currently evaluating, and has not yet
determined, the effect that the adoption of Statement of Financial Accounting
Standard 133 will have on its financial statements.

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 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. Statement of Position 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 Statement of Position 98-5 is not expected to have a material effect
on Wessex's financial position or results of operations.

     The three European Investment Bank currency term loans which are due and
payable from 1998 through June 2002 have both fixed and variable interest rates
in their respective currencies with semiannual interest payments. Using a
combination of interest rate swaps and currency swaps these rates are changed to
variable and fixed pounds sterling 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:

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
(pounds sterling) to the reporting currency (U.S. dollar).

of the free and matching shares on the grant date is written off to the income
statement in the year of issue. Employees are entitled to all dividends on these
shares when issued. At March 31, 1998, 452,623 ordinary shares were held by

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 the 12 month
London interbank offered rate plus 0.5%. Preference shares have priority on
winding up, but are non-voting unless a resolution is passed to vary their

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

NOTE 15 -- PENSIONS
 
   
     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 income statement has been
determined on the advice of independent qualified actuaries and is accrued over
the service lives of the employees expected to be eligible to receive such
benefits.
    
 
     The following assumptions were used in determining the funded status and
pension charge for each period, and are determined as of the beginning of the
period:

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

     On Friday July 24, 1998 Enron Corp. of Houston, Texas, United States, made
a cash offer of 630p per share for the shares of Wessex. This offer was
recommended to the stockholders by the Board of Directors of Wessex. The offer
ran to August 28, 1998, but was extended to September 18, 1998 to allow the
Secretary of State for Trade and Industry to consider if there should be an
investigation by the Monopolies and Mergers Commission. On September 10, 1998 it
was announced that there would be no reference to the Monopolies and Mergers
Commission. 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.

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.

shares were redeemed and Wessex Water Plc changed its name to Wessex Water Ltd.

     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, Credit
Suisse First Boston Corporation, Donaldson, Lufkin & Jenrette Securities
Corporation, PaineWebber Incorporated, BT Alex. Brown Incorporated and Banc of
America Securities LLC are acting as U.S. representatives. Under the U.S.
purchase agreement, and concurrently with the sale of 7,320,000 shares of common
stock to the international managers under 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 29,280,000
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 international managers and the U.S. underwriters, respectively, have agreed,
under the terms of those agreements, to purchase all of the shares of our common
stock being sold under those agreements if any of the shares of common stock
being sold under those agreements are purchased. In the event of a default by an
underwriter, the international purchase agreement and the U.S. purchase
agreement provide that, in some circumstances, the purchase commitments of
nondefaulting underwriters may be increased or the purchase agreements may be
terminated. The closings for the sale of shares of our common stock to the
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 some liabilities, including some liabilities under
the Securities Act, or to contribute to payments
 
                                       116
<PAGE>   186
 
the international managers and the U.S. underwriters may be required to make in
respect of those liabilities.
 
     The shares of common stock are being offered by the underwriters, subject
to prior sale, when, as and if issued to and accepted by them, subject to
approval of legal matters by counsel for the underwriters and certain other
conditions. The underwriters reserve the right to withdraw, cancel or modify
offers and to reject orders in whole or in part.
 
COMMISSIONS AND DISCOUNTS
 
     The lead managers have advised Azurix and the selling stockholder that the
international managers propose initially to offer the shares of our common stock
to the public at the initial public offering price set forth on the cover page
of this prospectus, and to certain dealers at such price less a concession not
in excess of $     per share of common stock. The international managers may
allow, and such dealers may reallow, a discount not in excess of $     per share
of common stock to certain other dealers. After the initial public offering, the
public offering price, concession and discount may be changed.
 
   
     The following table shows the per share and total public offering price,
the underwriting discount to be paid by Azurix and the selling stockholder to
the international managers and the U.S. underwriters and the proceeds before
expenses to Azurix and the selling stockholder. This information is presented
assuming either no exercise or full exercise by the international managers and
the U.S. underwriters of their over-allotment option.

     The expenses of this offering, exclusive of the underwriting discount, are
estimated at $5,250,000 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 1,098,000 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 conditions
specified in the purchase agreement, to purchase a number of additional shares
of our common stock proportionate to such international manager's initial amount
reflected in the foregoing table.
    
 
                                       117
<PAGE>   187
 
   
     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 4,392,000 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 3,660,000 of the shares offered hereby to be sold
to some of our directors, officers and employees who have expressed an interest
in purchasing our common stock. 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 that 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, Enron and the selling stockholder have agreed, with exceptions
specified in the lock-up agreements, not to directly or indirectly engage in the
following activities for a period of 180 days after the date of this prospectus
without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith
Incorporated:
    
 
     - Offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant for the sale of, lend or otherwise dispose of or
       transfer any shares of our common stock or securities convertible into or
       exchangeable or exercisable for or repayable with our common stock,
       whether now owned or later acquired by the person executing the agreement
       or with respect to which the person executing the agreement later
       acquires the power of disposition, or file a registration statement under
       the Securities Act relating to any shares of our common stock
 
     - Enter into any swap or other agreement that transfers, in whole or in
       part, the economic consequence of ownership of our common stock whether
       any such swap or transaction is to be settled by delivery of our common
       stock or other securities, in cash or otherwise, see "Shares Eligible for
       Future Sale"
 
     As an exception to these restrictions we may issue shares of our common
stock or securities convertible or exchangeable into our common stock as payment
of any part of the purchase price for businesses we acquire. However, shares
issued in this manner shall not be transferable during the 180-day lock-up
period. In addition, if Atlantic Water Trust is compelled to sell some or all of
its shares of our common stock in the event of a default under specified debt
obligations or a major decline in the price of Enron's common stock combined
with a downgrading of Enron's senior debt to below investment grade, then such
sale will be permitted. See "Risk Factors -- Future sales of our common stock
may depress our stock price."
 
NEW YORK STOCK EXCHANGE LISTING
 
   
     The common stock has been approved for listing on the New York Stock
Exchange under the symbol "AZX," subject to official notice of issuance. To meet
the requirements for listing of our common stock on that exchange, the
underwriters have undertaken to sell lots of 100 or more shares to a minimum of
2,000 beneficial owners.
    
 
     Before this offering, there has been no public market for our common stock.
The initial public offering price will be determined through negotiations among
Azurix, the selling stockholder, Enron, the lead managers and the U.S.
representatives. The factors to be considered in determining the initial public
offering price, in addition to prevailing market conditions, are the valuation
multiples of publicly traded companies that the lead managers and the U.S.
representatives believe to be comparable to us, including adjusted market value
to EBITDA multiples, price to book value multiples and price to earnings
multiples, certain of our financial information, the history of, and the
prospects for, our company and the industry in which we compete, an assessment
of our management, our past and present operations, the prospects for
 
                                       118
<PAGE>   188
 
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 this offering at or
above the initial public offering price.
 
     The underwriters do not expect sales of our common stock to any accounts
over which they exercise discretionary authority to exceed 5% of the number of
shares being offered in this offering.
 
PRICE STABILIZATION AND SHORT POSITIONS
 
     Until the distribution of our common stock is completed, rules of the SEC
may limit the ability of the underwriters and selling group members to bid for
and purchase our common stock. As an exception to these rules, the lead managers
and the U.S. representatives are permitted to engage in certain transactions
that stabilize the price of our common stock. Such transactions consist of bids
or purchases for the purpose of pegging, fixing or maintaining the price of our
common stock.
 
     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the lead managers and
the U.S. representatives may reduce that short position by purchasing our common
stock in the open market. The lead managers and the U.S. representatives may
also elect to reduce any short position by exercising all or part of the
over-allotment option described above.
 
PENALTY BIDS
 
     The lead managers and the U.S. representatives may also impose a penalty
bid on underwriters and selling group members. This means that if the lead
managers or the U.S. representatives purchase shares of our common stock in the
open market to reduce the underwriters' short position or to stabilize the price
of our common stock, they may reclaim the amount of the selling concession from
the underwriters and selling group members who sold those shares.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.
 
   
     None of Azurix, the selling stockholder, or any of the underwriters makes
any representation or prediction as to the direction or magnitude of any effect
that the transactions described above may have on the price of our common stock.
In addition, none of Azurix, the selling stockholder or any of the underwriters
makes any representation that the lead managers or the U.S. representatives will
engage in such transactions or that such transactions, once commenced, will not
be discontinued without notice.
    
 
OTHER RELATIONSHIPS
 
     Some of the underwriters and their affiliates engage in transactions with,
and perform services for, our company, Enron and Enron's affiliates in the
ordinary course of business and have engaged, and may in the future engage, in
commercial banking and investment banking transactions and services with our
company, Enron and Enron's affiliates, for which they have received customary
compensation.
 
   
     We have engaged Merrill Lynch & Co. to act as our financial advisor in
evaluating two potential acquisition opportunities for which we will pay an
ordinary and customary fee if we decide to pursue these opportunities and they
result in an acquisition. We have also agreed to reimburse Merrill Lynch & Co.
for all reasonable out-of-pocket expenses incurred in connection with these
engagements.
    
 
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.

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 Azurix.
    
 
   
     As permitted by the DGCL, the certificate of incorporation provides that
directors of Azurix shall have no personal liability to Azurix or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except (1) for any breach of the director's duty of loyalty to Azurix or its
stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation

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 Schedules. See Reports of Independent Public
Accountants and Independent Accountants included herein on Pages S-1 to S-3,

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.

                     RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                                  AZURIX CORP.

          (Pursuant to Sections 242 and 245 of the General Corporation
                         Law of the State of Delaware)

Certificate of Incorporation of the Corporation.

                                   ARTICLE I.

         The name of the Corporation is Azurix Corp.

                                  ARTICLE II.

                                  ARTICLE III.

         The purpose of the Corporation is to engage, directly or indirectly
(through affiliates or otherwise), in acquiring, owning, operating, and
managing water and wastewater assets, providing water- and wastewater- related
services, and developing and managing water resources, including without
limitation (i) the ownership, operation, and management of water supply and

production, collection, or storage of water), (iii) the ownership and operation
of real and personal property used or useful in connection with exploration for
water, development of water reserves upon discovery thereof, production of
water from wells located on water properties, and storage and transportation of
water including, but not limited to, water wells, water pipelines, water

activity that now or hereafter may be incidental to the foregoing purpose or
acquired as part of a larger acquisition transaction the majority of the value
of which (as determined by the Board of Directors of the Corporation or its
designee in good faith) relates to one or more of the foregoing purposes, but
excluding (in the case of each of items (i) through (xi)) supplying fuel,
supplying energy (other than sales of excess generation from facilities
principally serving assets or facilities described in items (i), (iii), (iv)
and (vii) above), or providing risk management services on a commodity other
than water (other than being a party to a risk management arrangement to
protect against risks facing the Corporation), and (xii) any other lawful
business or activity; provided that such other business or activity
contemplated by this clause (xii) is approved in writing by Enron Corp., an
Oregon corporation, which approval may be granted or withheld by Enron Corp. in
its sole discretion and which approval may be general in nature or may be
confined to a particular facility or a particularly described expanded business
purpose. Notwithstanding the foregoing, from and after the first date on which
both of the following tests are met: (a) Enron Corp. and affiliates of Enron
Corp. do not individually or collectively, directly or indirectly, own or have
the power to vote at least one-third of the capital stock of the Corporation
having ordinary voting power for the election of directors, and (b) fewer than
one-third of the directors of the Corporation are persons who are employees,
officers or directors of Enron Corp. or of any affiliate of Enron Corp., the
purpose of the Corporation shall be to engage in any lawful business or
activity in which a corporation organized under the laws of Delaware is
permitted to engage under Delaware law.

                                  ARTICLE IV.

         The total number of shares of stock that the Corporation shall have
authority to issue is, 550,000,000 shares of capital stock, consisting of (i)
500,000,000 shares of common stock, par value $.01 per share ("Common Stock"),
and (ii) 50,000,000 shares of preferred stock, par value $.01 per share
("Preferred Stock").

         The designations and the powers, preferences, rights, qualifications,
limitations, and restrictions of the Common Stock and the Preferred Stock are
as follows:

         1.      Provisions Relating to the Common Stock.

         (a)     Subject to the prior rights and preferences, if any,
applicable to shares of the Preferred Stock or any class or series thereof,
each share of Common Stock shall entitle the holder of record thereof to
receive dividends and other distributions in cash, stock of any corporation or
property of the Corporation when, as and if declared thereon by the Board of
Directors of the Corporation out





                                       2
<PAGE>   3
of assets or funds of the Corporation legally available therefor and shall
share equally on a per share basis in all such dividends and other
distributions.

         (b)     The holders of Common Stock shall be entitled to participate
in the net assets of the Corporation remaining after any dissolution,
liquidation or winding up of the affairs of the Corporation, whether voluntary
or involuntary, and after payment or provision for the payment of the debts and
liabilities of the Corporation and payment of the liquidation preference of any
shares of capital stock of the Corporation having such a preference,
distributing such proceeds pro-rata among the holders of Common Stock.  A
dissolution, liquidation or winding-up of the Corporation, as such terms are
used in this paragraph (b), shall not be deemed to be occasioned by or to
include any consolidation or merger of the Corporation with or into any other
corporation or corporations or other entity or a sale, lease, exchange, or
conveyance of all or a part of the assets of the Corporation.

         (c)     Each share of Common Stock shall entitle the registered holder
thereof to one vote on all matters brought before the common stockholders of
the Corporation for a vote.

         2.      Provisions Relating to the Preferred Stock.

         (a)     The Preferred Stock may be issued from time to time in one or
more classes or series, the shares of each class or series to have any
designations and powers, privileges, preferences, and rights, and
qualifications, limitations, and restrictions thereof as are stated and
expressed in this Article IV and in the resolution or resolutions providing for
the issue of such class or series adopted by the Board of Directors of the
Corporation as hereafter prescribed.

         (b)     Authority is hereby expressly granted to and vested in the
Board of Directors of the Corporation to authorize the issuance of the
Preferred Stock from time to time in one or more classes or series, and with
respect to each class or series of the Preferred Stock, to state by the
resolution or resolutions from time to time adopted providing for the issuance
thereof the following:

                 (i)      whether or not the class or series is to have voting
rights, special, or limited, or is to be without voting rights, and whether or
not such class or series is to be entitled to vote as a separate class either
alone or together with the holders of one or more other classes or series of
stock;

                 (ii)     the number of shares to constitute the class or
series and the designations thereof;

                 (iii)    the preferences and relative, participating,
optional, or other special rights, if any, and the qualifications, limitations,
or restrictions thereof, if any, with respect to any class or series;

                 (iv)     whether or not the shares of any class or series
shall be redeemable at the option of the Corporation or the holders thereof or
upon the happening of any specified event, and, if redeemable, the redemption
price or prices (which may be payable in the form of cash, notes, securities,
or other property), and the time or times at which, and the terms and
conditions upon which, such shares shall be redeemable and the manner of
redemption;





                                       3
<PAGE>   4
                 (v)      whether or not the shares of a class or series shall
be subject to the operation of retirement or sinking funds to be applied to the
purchase or redemption of such shares for retirement, and, if such retirement
or sinking fund or funds are to be established, the periodic amount thereof,
and the terms and provisions relative to the operation thereof;

                 (vi)     the dividend rate, whether dividends are payable in
cash, stock of the Corporation, or other property, the conditions upon which
and the times when such dividends are payable, the preference to or the
relation to the payment of dividends payable on any other class or classes or
series of stock, whether or not such dividends shall be cumulative or
noncumulative, and if cumulative, the date or dates from which such dividends
shall accumulate;

                 (vii)    the preferences, if any, and the amounts thereof
which the holders of any class or series thereof shall be entitled to receive
upon the voluntary or involuntary dissolution, liquidation or winding up of, or
upon any distribution of the assets of, the Corporation;

                 (viii)   whether or not the shares of any class or series, at
the option of the Corporation or the holder thereof or upon the happening of
any specified event, shall be convertible into or exchangeable for the shares
of any other class or classes or of any other series of the same or any other
class or classes of stock, securities, or other property of the Corporation and
the conversion price or prices or ratio or ratios or the rate or rates at which
such conversion or exchange may be made, with such adjustments, if any, as
shall be stated and expressed or provided for in such resolution or
resolutions; and

                 (ix)     any other special rights and protective provisions
with respect to any class or series as may to the Board of Directors of the
Corporation seem advisable.

         (c)     The shares of each class or series of the Preferred Stock may
vary from the shares of any other class or series thereof in any or all of the
foregoing respects and in any other manner.  The Board of Directors of the
Corporation may increase the number of shares of the Preferred Stock designated
for any existing class or series by a resolution adding to such class or series
authorized and unissued shares of the Preferred Stock not designated for any
other class or series.  The Board of Directors of the Corporation may decrease
the number of shares of the Preferred Stock designated for any existing class
or series by a resolution subtracting from such class or series authorized and
unissued shares of the Preferred Stock designated for such existing class or
series, and the shares so subtracted shall become authorized, unissued, and
undesignated shares of the Preferred Stock.

         3.      General.

         (a)     Subject to the foregoing provisions of this Restated
Certificate of Incorporation, the Corporation may issue shares of its Preferred
Stock and Common Stock from time to time for such consideration (not less than
the par value thereof) as may be fixed by the Board of Directors of the
Corporation, which is expressly authorized to fix the same in its absolute
discretion subject to the foregoing conditions.  Shares so issued for which the
consideration shall have been paid or delivered to the Corporation shall be
deemed fully paid stock and shall not be liable to any further call or
assessment thereon, and the holders of such shares shall not be liable for any
further payments in respect of such shares.





                                       4
<PAGE>   5
         (b)     The Corporation shall have authority to create and issue
rights and options entitling their holders to purchase shares of the
Corporation's capital stock of any class or series or other securities of the
Corporation, and such rights and options shall be evidenced by instrument(s)
approved by the Board of Directors of the Corporation.  The Board of Directors
of the Corporation shall be empowered to set the exercise price, duration,
times for exercise, and other terms of such rights or options; provided,
however, that the consideration to be received for any shares of capital stock
subject thereto shall not be less than the par value thereof.

                                   ARTICLE V.

         The Corporation shall have perpetual existence.

                                  ARTICLE VI.

         No holder of any shares of the Corporation, whether now or hereinafter
authorized, shall have any preemptive right to subscribe for or to purchase any
shares or other securities of the Corporation, nor have any right to cumulate
his votes for the election of directors.  Except as otherwise provided in this
Restated Certificate of Incorporation or the Bylaws or as otherwise required by
law, at all meetings of the stockholders of the Corporation, a quorum being
present, all matters shall be decided by a majority of the votes cast.  The
private property of the stockholders shall not be subject to the payment of
corporate debts to any extent whatever, but shall be exempt from corporate
liability.

                                  ARTICLE VII.

         The number, classification, and terms of the Board of Directors of the
Corporation and the procedures to elect directors, to remove directors, and to
fill vacancies in the Board of Directors shall be as follows:

         1.      The number of directors that shall constitute the whole Board
of Directors shall from time to time be fixed exclusively by the Board of
Directors by a resolution adopted by a majority of the whole Board of Directors
serving at the time of that vote.  In no event shall the number of directors
that constitute the whole Board of Directors be fewer than three.  No decrease
in the number of directors shall have the effect of shortening the term of any
incumbent director.  Directors of the Corporation need not be elected by
written ballot unless the Bylaws of the Corporation otherwise provide.

         2.      The Board of Directors of the Corporation shall be divided
into three classes designated Class I, Class II, and Class III, respectively,
all as nearly equal in number as possible, with each director then in office
receiving the classification that at least a majority of the Board of Directors
designates.  The initial term of office of directors of Class I shall expire at
the annual meeting of stockholders of the Corporation in 2000, of Class II
shall expire at the annual meeting of stockholders of the Corporation in 2001,
and of Class III shall expire at the annual meeting of stockholders of the
Corporation in 2002, and in all cases as to each director until his successor
is elected and qualified or until his earlier death, resignation or removal.
At each annual meeting of stockholders beginning with the annual meeting of
stockholders in 2000, each director elected to succeed a director whose term is
then expiring shall hold his office until the third annual meeting





                                       5
<PAGE>   6
of stockholders after his election and until his successor is elected and
qualified or until his earlier death, resignation or removal.  If the number of
directors that constitutes the whole Board of Directors is changed as permitted
by this Article VII, the majority of the whole Board of Directors that adopts
the change shall also fix and determine the number of directors comprising each
class; provided, however, that any increase or decrease in the number of
directors shall be apportioned among the classes as equally as possible.

         3.      Vacancies in the Board of Directors resulting from death,
resignation, retirement, disqualification, removal from office, or other cause
and newly-created directorships resulting from any increase in the authorized
number of directors may be filled by no less than a majority vote of the
remaining directors then in office, though less than a quorum, who are
designated to represent the same class or classes of stockholders that the
vacant position, when filled, is to represent or by the sole remaining director
(but not by the stockholders except as required by law), and each director so
chosen shall receive the classification of the vacant directorship to which he
has been appointed or, if it is a newly-created directorship, shall receive the
classification that at least a majority of the Board of Directors designates
and shall hold office until the first meeting of stockholders held after his
election for the purpose of electing directors of that classification and until
his successor is elected and qualified or until his earlier death, resignation,
or removal from office.

         4.      Prior to the first date (the "Trigger Date") upon which
neither Atlantic Water Trust nor Enron Corp.  (together with its subsidiaries)
is the holder of record of a majority of the outstanding voting stock of the
Corporation entitled to vote generally in the election of directors calculated
on a per vote basis, a director of any class of directors of the Corporation
may be removed before the expiration date of that director's term of office,
with or without cause, by an affirmative vote of the holders of a majority of
the votes of the outstanding shares of the class or classes or series of stock
then entitled to be voted at an election of directors of that class or series,
voting together as a single class, cast at the annual meeting of stockholders
or at any special meeting of stockholders called by a majority of the whole
Board of Directors for this purpose.  On and after the Trigger Date, a director
of any class of directors of the Corporation may be removed before the
expiration date of that director's term of office, only for cause, by an
affirmative vote of the holders of not less than sixty-six and two-thirds
percent (66 2/3%) of the votes of the outstanding shares of the class or
classes or series of stock then entitled to be voted at an election of
directors of that class or series, voting together as a single class, cast at
the annual meeting of stockholders or at any special meeting of stockholders
called by a majority of the whole Board of Directors for this purpose.

         5.      Notwithstanding any other provisions of this Restated
Certificate of Incorporation or any provision of law that might otherwise
permit a lesser or no vote, but in addition to any affirmative vote of the
holders of any particular class or series of the capital stock of the
Corporation required by law or by this Restated Certificate of Incorporation,
the affirmative vote of the holders of not less than sixty-six and two-thirds
percent (66 2/3%) of the votes of the outstanding shares of the Corporation
then entitled to be voted in an election of directors, voting together as a
single class, shall be required on and after the Trigger Date to amend or
repeal, or to adopt any provision inconsistent with, this Article VII.

<PAGE>   7
                                 ARTICLE VIII.

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors of the Corporation is expressly authorized:

         1.      To make, alter, amend and rescind the Bylaws of the
                 Corporation.

         2.      To set apart out of any of the available funds of the
Corporation such reserves for proper purposes as the Board of Directors of the
Corporation may deem expedient, and to abolish any such reserves.

         3.      To determine the use and distribution of any surplus and net
                 profits.

         4.      To authorize and cause to be executed and delivered, without
limit as to amount, mortgages and instruments of pledge of, and other
instruments creating liens upon, the real and personal property of the
Corporation.

         5.      From time to time, to determine whether and to what extent and
at what times and places and under what conditions and regulations the accounts
and books of the Corporation (other than the stock ledger) or any of them,
shall be open to the inspection of the stockholders, and no stockholder shall
have any right to inspect any account or book or document of the Corporation,
except as conferred by statute, or authorized by the Board of Directors or by a
resolution of the stockholders.

         6.      By resolution or resolutions, passed by a majority of the
whole Board of Directors, to designate one or more committees to consist of one
or more of the directors of the Corporation, which, to the extent provided in
said resolution or resolutions or in the Bylaws of the Corporation, shall have
and may exercise the powers of the Board of Directors in the management of the
business and affairs of the Corporation, and may have power to authorize the
seal of the Corporation to be affixed to all papers which may require it.  Such
committee or committees shall have such name or names as may be stated in the
Bylaws of the Corporation or as may be determined from time to time by
resolution adopted by the Board of Directors.

         This Corporation may in its Bylaws confer powers and authority upon
its Board of Directors in addition to the foregoing and in addition to the
powers and authorities expressly conferred upon it by statute.

                                  ARTICLE IX.

         Prior to the Trigger Date, any action required or permitted to be
taken by the stockholders of the Corporation may be taken without a meeting if
a consent in writing, setting forth the action so taken, is signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted.  On and after the
Trigger Date, any action required or permitted to be taken by the stockholders
of the Corporation must be taken at a duly held annual or special meeting of
stockholders and may not be taken by any consent in writing of such
stockholders.





                                       7
<PAGE>   8
                                   ARTICLE X.

         Special meetings of the stockholders of the Corporation, and any
proposals to be considered at such meetings, may be called and proposed
exclusively by the Board of Directors, pursuant to a resolution approved by a
majority of the members of the Board of Directors at the time in office, and no
stockholder of the Corporation shall require the Board of Directors to call a
special meeting of common stockholders or to propose business at a special
meeting of stockholders.  Notwithstanding any other provisions of this Restated
Certificate of Incorporation or any provision of law that might otherwise
permit a lesser or no vote, but in addition to any affirmative vote of the
holders of any particular class or series of the capital stock of the
Corporation required by law or by this Restated Certificate of Incorporation,
the affirmative vote of the holders of not less than sixty-six and two-thirds
percent (66 2/3%) of the votes of the shares of the Corporation then entitled
to be voted in an election of directors, voting together as a single class,
shall be required on and after the Trigger Date to amend or repeal, or to adopt
any provision inconsistent with, this Article X.

                                  ARTICLE XI.

         1.      Each person who was or is made a party or is threatened to be
made a party to or is involved in any action, suit or proceeding, whether
civil, criminal, administrative or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she, or a person of whom he or she is the
legal representative, is or was a director or officer of the Corporation or is
or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans, whether the basis of such proceeding is alleged action in an official
capacity as a director, officer, employee or agent or in any other capacity
while serving as a director, officer, employee or agent, shall be indemnified
and held harmless by the Corporation to the fullest extent authorized by the
Delaware General Corporation Law, as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights
than said law permitted the Corporation to provide prior to such amendment),
against all expense, liability and loss (including attorneys' fees, judgments,
fines, ERISA excise taxes or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators; provided, however, that except
as provided in paragraph 2 of this Article XI, the Corporation shall indemnify
any such person seeking indemnification in connection with a proceeding (or
part thereof) initiated by such person only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.  The
right to indemnification conferred in this Article XI shall be a contract right
and shall include the right to be paid by the Corporation the expenses incurred
by defending any such proceeding in advance of its final disposition; provided,
however, that, if the Delaware General Corporation Law requires, the payment of
such expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of a proceeding, shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such director or officer, to
repay all amounts so advanced if it shall ultimately be determined that such
director or officer is not entitled to be indemnified under this Article XI or
otherwise.  The Corporation may, by action of its Board of Directors, provide





                                       8
<PAGE>   9
indemnification to employees and agents of the Corporation with the same scope
and effect as the foregoing indemnification of directors and officers.

         2.      If a claim under paragraph 1 of this Article XI is not paid in
full by the Corporation within thirty days after a written claim has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim.  It shall be a defense to any such
action (other than an action brought to enforce a claim for expenses incurred
in defending any proceeding in advance of its final disposition where the
required undertaking, if any is required, has been tendered to the Corporation)
that the claimant has not met the standards of conduct which make it
permissible under the Delaware General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation.  Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
Delaware General Corporation Law, nor an actual determination by the
Corporation (including its Board of Directors, independent legal counsel, or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

         3.      The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition
conferred in this Article XI shall not be exclusive of any other right which
any person may have or hereinafter acquire under any statute, provision of the
Restated Certificate of Incorporation, bylaw, agreement, vote of stockholders
or disinterested directors or otherwise.

         4.      The Corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the Corporation,
or another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such expense, liability
or loss under the Delaware General Corporation Law.


                                  ARTICLE XII.

         A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.  Any repeal or amendment of this Article XIII by the
stockholders of the Corporation shall be prospective only, and shall not
adversely affect any limitation on the personal liability of a director of the
Corporation arising from an act or omission occurring prior to the time of such
repeal or amendment.  In addition to the circumstances in which a director of
the Corporation is not personally liable as set forth in the foregoing
provisions of this Article XII, a director shall not be liable to the
Corporation or its stockholders to such further





                                       9

extent as permitted by any law hereafter enacted, including, without
limitation, any subsequent amendment to the Delaware General Corporation Law.

                                 ARTICLE XIII.

         The provisions of Section 203 of the Delaware General Corporation Law
shall not be applicable to the Corporation.

                                  ARTICLE XIV.

         The stockholders and Board of Directors of the Corporation shall have
the power, if the Bylaws so provide, to hold their meetings and to keep the
books of the Corporation (except such as are required by the laws of Delaware
to be kept in Delaware) and documents and papers of the Corporation outside the
State of Delaware and have one or more offices within or without the State of
Delaware at such places as may be designated from time to time by the Board of
Directors.

                                  ARTICLE XV.

         The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Restated Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

                                       OF

                                  AZURIX CORP.


                                   Article I

                                    Offices

         Section 1. Registered Office . The registered office of the
Corporation required by the state of incorporation of the Corporation to be
maintained in the state of incorporation of the Corporation shall be the
registered office named in the original charter documents of the Corporation,
or such other office as may be designated from time to time by the Board of
Directors in the manner provided by law.

         Section 2. Other Offices. The Corporation may also have offices at
such other places both within and without the state of incorporation of the
Corporation as the Board of Directors may from time to time determine or the
business of the Corporation may require.

                                   Article II

                                  Stockholders

         Section 1. Place of Meetings. All meetings of the stockholders shall
be held at the principal office of the Corporation, or at such other place
within or without the state of incorporation of the Corporation as shall be
specified or fixed in the notices or waivers of notice thereof.

         Section 2. Quorum; Adjournment of Meetings. Unless otherwise required
by law or provided in the charter documents of the Corporation or these Bylaws,
(i) the holders of a majority of the voting power attributable to the stock
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at any meeting of stockholders
for the transaction of business, (ii) in all matters other than election of
directors, the affirmative vote of the holders of a majority of the voting
power attributable to such stock so present or represented at any meeting of
stockholders at which a quorum is present shall constitute the act of the
stockholders, and (iii) where a separate vote by a class or classes is
required, a majority of the voting power attributable to the outstanding shares
of such class or classes, present in person or represented by proxy shall
constitute a quorum entitled to take action with respect to that vote on that
matter and the affirmative vote of the majority of the voting power
attributable to the shares of such class or classes present in person or
represented by proxy at the meeting shall be the act of such class.

         Directors shall be elected by a plurality of the votes of the shares
present in person or represented by proxy at the meeting and entitled to vote
on the election of directors.



                                       1
<PAGE>   5

Notwithstanding the other provisions of the charter documents of the
Corporation or these Bylaws, the chairman of the meeting or the holders of a
majority of the voting power attributable to the issued and outstanding stock,
present in person or represented by proxy and entitled to vote thereat, at any
meeting of stockholders, whether or not a quorum is present, shall have the
power to adjourn such meeting from time to time, without any notice other than
announcement at the meeting of the time and place of the holding of the
adjourned meeting. If the adjournment is for more than thirty (30) days, or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at such meeting. At such adjourned meeting at which a quorum
shall be present or represented any business may be transacted which might have
been transacted at the meeting as originally called.

Section 3. Annual Meetings. An annual meeting of the stockholders, for the
election of directors to succeed those whose terms expire and for the
transaction of such other business as may properly come before the meeting,
shall be held at such place (within or without the state of incorporation of
the Corporation), on such date, and at such time as the Board of Directors
shall fix and set forth in the notice of the meeting, which date shall be
within thirteen (13) months subsequent to the last annual meeting of
stockholders.

Section 4. Special Meetings. Unless otherwise provided in the charter documents
of the Corporation, special meetings of the stockholders for any purpose or
purposes may be called at any time by the Chairman of the Board, by any Vice
Chairman of the Board, by the President, by any Executive Director, by a
majority of the Board of Directors, or by a majority of the Executive Committee
(if any), at such time and at such place as may be stated in the notice of the
meeting. Business transacted at a special meeting shall be confined to the
purpose(s) stated in the notice of such meeting.

Section 5. Record Date. For the purpose of determining stockholders entitled to
notice of or to vote at any meeting of stockholders, or any adjournment
thereof, or entitled to receive payment of any dividend or other distribution
or allotment of any rights, or entitled to exercise any rights in respect of
any change, conversion or exchange of stock or for the purpose of any other
lawful action, the Board of Directors of the Corporation may fix a date as the
record date for any such determination of stockholders, which record date shall
not precede the date on which the resolutions fixing the record date are
adopted and which record date, in the case of a meeting of stockholders, shall
not be more than sixty (60) days nor less than ten (10) days before the date of
such meeting of stockholders, nor, in the case of any other action, more than
sixty (60) days prior to any such action.

If the Board of Directors does not fix a record date for any meeting of the
stockholders, the record date for determining stockholders entitled to notice
of or to vote at such meeting shall be at the close of business on the third
business day next preceding the day on which notice is given. If the Board of
Directors does not fix the record date for determining stockholders for any
other purpose, the record date shall be at the close of business on the day on
which the Board of Directors adopts the resolution relating thereto. A
determination of stockholders of record entitled to notice of or to vote at a




                                       2
<PAGE>   6

meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for
the adjourned meeting.

For the purpose of determining the stockholders entitled to consent to
corporate action in writing without a meeting, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten (10) days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If the
Board of Directors does not fix the record date, the record date for
determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is necessary,
shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the Corporation at its
registered office in the state of incorporation of the Corporation, at its
principal place of business, or an officer or agent of the Corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to a corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested. If the Board of
Directors does not fix the record date, and prior action by the Board of
Directors is necessary, the record date for determining stockholders entitled
to consent to corporate action in writing without a meeting shall be at the
close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.

Section 6. Notice of Meetings. Written notice of the place, date and hour of
all meetings, and, in case of a special meeting, the purpose or purposes for
which the meeting is called, shall be given by or at the direction of the
Chairman of the Board, a Vice Chairman of the Board, the President, an
Executive Director, the Secretary or other person(s) calling the meeting to
each stockholder entitled to vote thereat not less than ten (10) nor more than
sixty (60) days before the date of the meeting. Such notice is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at such stockholder's address as it appears on the records of the
Corporation.

Section 7. Stockholder List. A complete list of stockholders entitled to vote
at any meeting of stockholders, arranged in alphabetical order for each class
of stock and showing the address of each such stockholder and the number of
shares registered in the name of such stockholder, shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or if not so
specified, at the place where the meeting is to be held. The stockholder list
shall also be produced and kept at the time and place of the meeting during the
whole time thereof, and may be inspected by any stockholder who is present.

Section 8. Proxies. Each stockholder entitled to vote at a meeting of
stockholders may authorize another person or persons to act for him by proxy.
Proxies for use at any meeting of stockholders shall be filed with the
Secretary, or such other officer as the Board of Directors may from time to
time determine by resolution, before or at the time of the meeting. All proxies
shall be received and taken charge of and all ballots shall be 



                                       3
<PAGE>   7

received and canvassed by the secretary of the meeting, who shall decide all
questions touching upon the qualification of voters, the validity of the
proxies, and the acceptance or rejection of votes, unless an inspector or
inspectors shall have been duly appointed as provided in Section 9 of Article
II hereof, in which event such inspector or inspectors shall decide all such
questions.

No proxy shall be valid after three (3) years from its date, unless the proxy
provides for a longer period. Each proxy shall be revocable unless expressly
provided therein to be irrevocable and coupled with an interest sufficient in
law to support an irrevocable power.

Should a proxy designate two or more persons to act as proxies, unless such
instrument shall provide the contrary, a majority of such persons present at
any meeting at which their powers thereunder are to be exercised shall have and
may exercise all the powers of voting or giving consents thereby conferred, or
if only one be present, then such powers may be exercised by that one; or, if
an even number attend and a majority do not agree on any particular issue, each
person designated to act as proxy and so attending shall be entitled to
exercise such powers in respect of such portion of the shares as is equal to
the reciprocal of the fraction equal to the number of persons designated to act
as proxies and in attendance divided by the total number of shares represented
by such proxies.

Section 9. Voting; Elections; Inspectors. Unless otherwise required by law or
provided in the charter documents of the Corporation, each stockholder shall on
each matter submitted to a vote at a meeting of stockholders have one vote for
each shares of stock entitled to vote which is registered in his name on the
record date for the meeting. For the purposes hereof, each election to fill a
directorship shall constitute a separate matter. Shares registered in the name
of another corporation, domestic or foreign, or other legal entity may be voted
by such officer, agent or proxy as the bylaws (or comparable instrument) of
such corporation or other legal entity may prescribe, or in the absence of such
provisions, as the Board of Directors (or comparable body) of such corporation
or other legal entity may determine. Shares registered in the name of a
deceased person may be voted by the executor or administrator of such person's
estate, either in person or by proxy.

All voting, except as required by the charter documents of the Corporation or
where otherwise required by law, may be by a voice vote; provided, however,
upon request of the chairman of the meeting or upon demand therefor by
stockholders holding a majority of the issued and outstanding stock present in
person or by proxy at any meeting a stock vote shall be taken. Every stock vote
shall be taken by written ballots, each of which shall state the name of the
stockholder or proxy voting and such other information as may be required under
the procedure established for the meeting. All elections of directors shall be
by written ballots, unless otherwise provided in the charter documents of the

ratified by the vote of the stockholders holding a majority of the voting power
attributable to the issued and outstanding shares of stock of the Corporation

Section 1. Certificates of Stock. The certificates for shares of the capital
stock of the Corporation shall be in such form, not inconsistent with that
required by law and the charter documents of the Corporation, as shall be
approved by the Board of Directors. Every holder of stock represented by
certificates shall be entitled to have a certificate signed by or in the name
of the Corporation by the Chairman of the Board, an Executive Director,
President, a Vice Chairman of the Board or a Vice President and the Secretary,

signatures on the certificate may be facsimile. The stock record books and the
blank stock certificate books shall be kept by the Secretary, or at the office
of such transfer agent or transfer agents as the Board of Directors may from

shall have signed or whose facsimile signature or signatures shall have been
placed upon any such certificate or certificates shall have ceased to be such
officer, transfer agent or registrar before such certificate is issued by the
Corporation, such certificate may nevertheless be issued by the Corporation
with the same effect as if such person were such officer, transfer agent or
registrar at the date of issue. The stock certificates shall be consecutively
numbered and shall be entered in the books of the Corporation as they are
issued and shall exhibit the holder's name and number of shares.

Section 2. Transfer of Shares. The shares of stock of the Corporation shall be
transferable only on the books of the Corporation by the holders thereof in
person or by their duly authorized attorneys or legal representatives upon
surrender and cancellation of certificates for a like number of shares. Upon
surrender to the Corporation or a transfer agent of the Corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
Corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

Section 3. Ownership of Shares. The Corporation shall be entitled to treat the
holder of record of any share or shares of capital stock of the Corporation as
the holder in fact thereof and, accordingly, shall not be bound to recognize
any equitable or other claim to or interest in such share or shares on the part
of any other person, whether or not it shall have express or other notice
thereof, except as otherwise provided by the laws of the state of incorporation
of the Corporation.

replacement of certificates for shares of capital stock of the Corporation.

Section 5. Lost or Destroyed Certificates. The Board of Directors may determine
the conditions upon which the Corporation may issue a new certificate of stock
in place of a certificate theretofore issued by it which is alleged to have
been lost, stolen or destroyed and may require the owner of such certificate or
such owner's legal representative to give bond, with surety sufficient to
indemnify the Corporation and each transfer agent and registrar against any and
all losses or claims which may arise by reason of the alleged loss, theft or
destruction of any such certificate or the issuance of such new certificate in
the place of the one so lost, stolen or destroyed.

                            Miscellaneous Provisions

Section 1. Fiscal Year. The fiscal year of the Corporation shall end on the
last day of December of each year.

shall have inscribed thereon the name of the Corporation and the state of its
incorporation, which seal shall be in the charge of the Secretary and shall be
affixed to certificates of stock, debentures, bonds, and other documents, in
accordance with the direction of the Board of Directors, and as may be required
by law; however, the Secretary may, if the Secretary deems it expedient, have a
facsimile of the corporate seal inscribed on any such certificates of stock,
debentures, bonds, contracts or other documents. Duplicates of the seal may be
kept for use by the Deputy Corporate Secretary or any Assistant Secretary.

Section 3. Notice and Waiver of Notice. Whenever any notice is required to be
given by law, the charter documents of the Corporation or under the provisions
of these Bylaws, said notice shall be deemed to be sufficient if given (i) by
telegraphic, cable or wireless transmission (including by telecopy or facsimile
transmission) or (ii) by deposit of the same in a post office box or by
delivery to an overnight courier service company in a sealed prepaid wrapper
addressed to the person entitled thereto at such person's post office address,
as it appears on the records of the Corporation, and such notice shall be
deemed to have been given on the day of such transmission or mailing or
delivery to courier, as the case may be.

Whenever notice is required to be given by law, the charter documents of the
Corporation or under any of the provisions of these Bylaws, a written waiver
thereof, signed by the person entitled to notice, whether before or after the
time stated therein, shall be deemed equivalent to notice. Attendance of a
person, including without limitation a director, at a meeting shall constitute
a waiver of notice of such meeting, except when the person attends a meeting
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. 



                                      17
<PAGE>   21

Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the stockholders, directors, or members of a committee of
directors need be specified in any written waiver of notice unless so required
by the charter documents of the Corporation or these Bylaws.

Section 4. Facsimile Signatures. In addition to the provisions for the use of
facsimile signatures elsewhere specifically authorized in these Bylaws,
facsimile signatures of any officer or officers of the Corporation may be used
whenever and as authorized by the Board of Directors.

Section 5. Reliance upon Books, Reports and Records. A member of the Board of
Directors, or a member of any committee designated by the Board of Directors,
shall, in the performance of such person's duties, be fully protected in
relying in good faith upon the records of the Corporation and upon such
information, opinion, reports or statements presented to the Corporation by any
of the Corporation's officers or employees, or committees of the Board of
Directors, or by any other person as to matters the member reasonably believes
are within such other person's professional or expert competence and who has
been selected with reasonable care by or on behalf of the Corporation.

Section 6. Application of Bylaws. In the event that any provisions of these
Bylaws is or may be in conflict with any law of the United States, of the state
of incorporation of the Corporation or of any other governmental body or power
having jurisdiction over this Corporation, or over the subject matter to which
such provision of these Bylaws applies, or may apply, such provision of these
Bylaws shall be inoperative to the extent only that the operation thereof
unavoidably conflicts with such law and shall in all other respects be in full
force and effect.

                                  Article VIII

                                   Amendments

The Board of Directors shall have the power to adopt, amend and repeal from
time to time Bylaws of the Corporation, subject to the right of the
stockholders entitled to vote with respect thereto to amend or repeal such
Bylaws as adopted or amended by the Board of Directors.

2.1      FACILITY

         other Finance Party under the Finance Documents.

         to be necessary to reflect the change in currency and to put the Banks
         (and, if possible and practicable, the Company) in the same position,
         so far as possible, that they would have been in if no change in
         currency had occurred.

3.       PURPOSE AND AVAILABILITY

         (ii)  refinancing the outstanding Loan Notes; and/or

         (iii) making Inter-Company Loans up to a maximum aggregate amount of

                   Company. If the duration of that Interest Period cannot be
                   agreed by the latest time on which a Request can be delivered
                   for that Loan under Clause 5.1 (Receipt of Requests), the
                   Facility Agent shall stipulate the duration of that Interest
                   Period. In each case, the Facility Agent and the Company
                   shall act reasonably and have

                                       20


                   regard to the nature of the Event of Default, any cure period
                   and the likely time period needed for the Banks to respond to
                   the waiver request;

         (b)  it would not cause the Loans to exceed the Total Commitments;

         (c)  it would not result in there being more than 10 Loans outstanding
              at any time; and

         (d)  if the Loan is to finance an Inter-Company Loan, that

                    such amendments as the Facility Agent may agree,

              provided that no Loan may be drawn to finance the initial making
              of an Inter-Company Loan if the Issuer Credit Rating of the
              Company is less than BBB from Standard & Poor's or Baa2 from

         banking policies or be otherwise prejudicial to it.

8.2      SELECTION OF AN OPTIONAL DURATION

(a)      Subject to Clause 4.2(a)(iii) (Further conditions precedent), if the

9.1      INTEREST RATE

         The rate of interest on each Loan for each of its Interest Periods is

         of the applicable:-

         (a)  Margin;

         (b)  LIBOR; and

         (c)  Mandatory Costs.

9.2      DUE DATES

         Except as otherwise provided in this Agreement, accrued interest on
         each Loan is payable by the Company on the last day of each Interest
         Period and also, in the case of a Loan with an Interest Period longer
         than six months, on the date falling six months after the commencement
         of that Interest Period.

9.3      DEFAULT INTEREST

(a)      (i)  If the Company fails to pay any amount payable by it under the
              Finance Documents, it shall forthwith on demand by the Facility
              Agent pay interest on the overdue amount from the due date up to
              the date of actual payment, as well after as before judgement, at
              a rate (the "DEFAULT RATE") determined by the Facility Agent to be
              1 per cent. per annum above, subject to sub-paragraph (ii) below,
              the rate which would have been payable if the overdue amount had,
              during the period of non-payment, constituted a Loan for such
              successive Interest Periods of such duration as the Facility Agent
              may reasonably determine having regard to the likely duration of
              the default (each a "DESIGNATED INTEREST PERIOD").

         (ii) If the overdue amount is a principal amount of a Loan and it
              becomes due and payable prior to the last day of an Interest
              Period for that Loan, then:-

                  (1)      the first Designated Interest Period for that overdue
                           sum will be the unexpired portion of that Interest
                           Period; and

                  (2)      the rate of interest on the overdue amount for that
                           first Designated Interest Period will be 1 per cent.
                           per annum above the rate on the overdue amount under
                           Clause 9.1 (Interest rate) immediately before the due
                           date.

                  After the expiry of the first Designated Interest Period for
                  that overdue amount, the rate on the overdue amount will be
                  calculated in accordance with sub-paragraph (i) above.
<PAGE>   28
                                       25


(b)      The default rate will be determined on each Business Day or the first
         day of the relevant Designated Interest Period, as appropriate.

(c)      If the Facility Agent determines that deposits are not at the relevant
         time being made available by the Reference Banks to leading banks in
         the London interbank market, the default rate will be determined by
         reference to the cost of funds to the Banks from whatever sources the
         Banks may reasonably select, having due regard to the likely duration
         of the default.

(d)      Default interest will be compounded at the end of each Designated
         Interest
         Period.

9.4      NOTIFICATION OF RATES OF INTEREST

         relevant Request.

(b)      The currency of each Loan must be Sterling or an Optional Currency.

(c)      If the Company fails to give a notice in respect of an outstanding Loan
         in accordance with paragraph (a) above, that Loan will be denominated
         in Sterling.

10.2     REVOCATION OF CURRENCY

         If before 9.30 a.m. on any Rate Fixing Day, the Facility Agent receives
         notice from a Bank that:-

         (a)  it is impracticable for the Bank to fund its participation in the
              Loan in the relevant Optional Currency during that Interest Period
              in the ordinary course of business in the London interbank market;
              and/or

         (b)  the use of the proposed Optional Currency could reasonably be
              expected to contravene any law or regulation,

         the Facility Agent shall give notice to the Company and to the Banks to
         that effect before 11.00 a.m. on that day. In this event:-

         (i)  the Company and the Banks may agree that the drawdown will not be
              made or will be made in Sterling; or

         (ii) in the absence of agreement and in any other case:

              (1)  that Bank's participation in the Loan (or, if more than one
                   Bank is similarly affected, those Banks' participations in
                   the Loan) shall be treated as a separate Loan denominated in
                   Sterling during the relevant Interest Period;
<PAGE>   29
                                       26


              (2)  in the definition of "LIBOR" (insofar as it applies to that
                   Loan) in Clause 1.1 (Definitions):

                   (A)  there shall be substituted for the time "11.00 a.m." the
                        time "1.00 p.m."; and

                   (B)  paragraph (c) shall apply.

10.3     DRAWDOWNS

         If a Loan is to be drawn in an Optional Currency, the amount of each
         Bank's participation in that Loan will be determined by converting into
         that Optional Currency the Bank's participation in the Original
         Sterling Amount of that Loan on the basis of the Agent's Spot Rate of
         Exchange two Business Days before its Drawdown Date.

10.4     PREPAYMENTS AND REPAYMENTS

         If a Loan is to be prepaid by reference to an Original Sterling Amount,
         the Optional Currency amount to be repaid or prepaid shall be
         determined by reference to the Agent's Spot Rate of Exchange used for
         determining the Optional Currency amount of that Loan under this Clause
         10 for the making of that Loan.

10.5     NOTIFICATION

         The Facility Agent shall notify the Banks and the Company of Optional
         Currency amounts (and the applicable Agent's Spot Rate of Exchange)
         promptly after they are ascertained.

11.      DEBT SERVICE RESERVE ACCOUNT

11.1     DESIGNATION OF ACCOUNTS

         The Company shall maintain a deposit account in the name of the Company
         designated the "DEBT SERVICE RESERVE ACCOUNT" at the Security Agent (or
         an Affiliate of the Security Agent).

11.2     DEBT SERVICE RESERVE ACCOUNT

(a)      The Company shall, for so long as any amount in respect of principal,
         interest or fees payable under the Finance Documents is outstanding or

         Account:

         (i)  on the date of this Agreement, an amount of not less than

                   fund an advance to Enron Corp. or any of its Affiliates
                   (including the Parent), provided that the Company has the
                   benefit of a guarantee or an on demand letter of credit in
                   each case, in form and substance reasonably satisfactory to
                   the Facility Agent and the Security Agent (in each case from

                   case, in form and substance reasonably satisfactory to the

               due but unpaid under this Agreement;

         All payments by the Company under the Finance Documents 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 the Company 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, or paid or payable by an Agent to a Bank, under the Finance
         Documents, the Company shall pay such additional amounts as may be
         necessary to ensure that the relevant Bank receives a net amount equal
         to the full amount which it would have received had payment not been
         made subject to tax or other deduction.

13.2     TAX RECEIPTS

         All taxes required by law to be deducted or withheld by the Company
         from any amounts paid or payable under the Finance Documents shall be

         the payment being made, deliver to the Facility Agent for the relevant
         Bank evidence reasonably satisfactory to that Bank (including all

13.3     REFUND OF TAX CREDITS

         If:-

         (a)      the Company makes a payment under Clause 13.1 (Gross-up) (a
                  "TAX PAYMENT") in respect of a payment to a Bank under the
                  Finance Documents; and

         (b)      that Bank 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 that Bank 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 the Bank, that Bank shall forthwith
         reimburse the Company such amount as that Bank in its absolute
         discretion determines to be such proportion of that Tax Credit as will
         leave that Bank (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. A Bank 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 13.3 (and, if so,
         what amount and when). No Bank shall be obliged to disclose any
         information regarding its tax affairs and computations.

13.4     QUALIFYING BANK

(a)      Each Bank party to this Agreement on the date of this Agreement
         represents that it is a Qualifying Bank on the date of this Agreement.
         Any bank or financial institution which becomes a Bank after the date
         of this Agreement pursuant to Clause 27.2 (Transfers by Banks) or
         otherwise represents to the Company on the date it becomes a Party
         that, as at that date, it is a Qualifying Bank.

(b)      If, otherwise than as a result of the introduction of, change in, or
         any change in the interpretation, administration or application of, any
         law or regulation, any Double Taxation Treaty or any practice or
         concession of the United Kingdom Inland Revenue occurring after the
         date a Bank becomes a Party, the Bank is not or ceases to be a
         Qualifying Bank, the Company will not be liable to pay to that Bank
         under Clause 13.1 (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. in excess
         of the amount it would have been obliged to pay if that Bank had been
         or had not ceased to be a Qualifying Bank.

(c)      Any Bank which falls within paragraph (b) of the definition of
         Qualifying Bank shall:

         (i)  promptly 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 to the Company under the Double
              Taxation Relief (Taxes on Income) (General) Regulations 1970 that
              the Company should not, on account of the relevant Double Taxation
              Treaty, pay any interest due to the Bank under the Finance
              Documents under deduction of U.K. tax. The Bank concerned shall,
              upon the request of the Company, promptly and duly (if it is able
              to do so) execute and deliver any and all such further instruments
              and documents which are required for the purpose of obtaining such
              a direction; or
<PAGE>   35
                                       32


         (ii) use all reasonable endeavours to transfer its rights, obligations
              and Commitments to a Qualifying Bank from which it is not illegal
              for any member of the AEL Group or its Affiliates to borrow within
              90 days of the date of becoming aware that the relevant Double Tax
              Treaty has ceased to apply or no longer gives full exemption to
              that Bank from United Kingdom taxation on interest, provided that
              the consent of the Company shall not be required under Clause 27.2
              (Transfers by Banks) for such a transfer.

(d)      The Company will not be liable to pay to a Bank under Clause 13.1
         (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 that Bank had performed its obligations under
         paragraph (c) above (whether or not then requested to do so pursuant to
         that paragraph (c)).

(e)      Each Bank shall notify the Company through the Facility Agent as soon
         as it is aware that it ceases to be a Qualifying Bank.

14.      MARKET DISRUPTION

(a)      If LIBOR is to be determined by reference to the Reference Banks but a
         Reference Bank does not supply an offered rate by 11.30 a.m. on a Rate
         Fixing Day, the applicable LIBOR shall, subject to paragraph (b) below,
         be determined on the basis of the quotations of the remaining Reference
         Banks.

(b)      If, in relation to any proposed Loan:-

         (i)      LIBOR is to be determined by reference to the Reference Banks
                  but no, or only one, Reference Bank supplies a rate for the
                  purposes of determining the applicable LIBOR or the Facility
                  Agent otherwise determines that adequate and fair means do not
                  exist for ascertaining the applicable LIBOR; or

         (ii)     the Facility Agent receives notification from Banks whose
                  participations in a Loan exceed 50 per cent. of that Loan
                  that, in their opinion:-

                  (A)      matching deposits may not be available to them in the
                           London interbank market in the ordinary course of
                           business to fund their participations in that Loan
                           for the relevant Interest Period; or

                  (B)      the cost to them of matching deposits in the London
                           interbank market would be in excess of the relevant
                           LIBOR,

         the Facility Agent shall promptly notify the Company and the relevant
         Banks of the fact and that this Clause 14 is in operation.

(c)      After any notification under paragraph (b) above:-

         (i)      unless the Company notifies the Facility Agent to the contrary
                  before close of business on the day it received the
                  notification under paragraph (b) above, the Loan shall still
                  be made but it shall have an Interest Period of one month and
                  the interest payable on that Loan shall be determined in
                  accordance with sub-paragraphs (ii) to (vi) below; and
<PAGE>   36
                                       33


         (ii)     promptly after receipt of the notification, the Company and
                  the Facility Agent shall enter into negotiations in good faith
                  for a period of not more than one month with a view to
                  agreeing a substitute basis for determining the rate of
                  interest and/or funding applicable to the Loan affected by the
                  notification;

         (iii)    any substitute basis agreed under sub-paragraph (ii) above
                  shall be, with the prior consent of all the Banks, binding on
                  all the Parties;

         (iv)     if no substitute basis is agreed under sub-paragraph (ii)
                  above, each Bank (through the Facility Agent) shall certify on
                  or before the last day of the Interest Period to which the
                  notification relates an alternative basis for maintaining its
                  participation in that Loan;

         (v)      any alternative basis referred to in sub-paragraph (iv) above
                  may include an alternative method of fixing the interest rate,
                  alternative Interest Periods or alternative Optional
                  Currencies or, as the case may be, Sterling but it must
                  reflect the cost to the Banks of funding their participations
                  in that Loan from whatever sources each relevant Bank may
                  reasonably select (each Bank's cost of funding being certified
                  by that Bank with a copy to the Facility Agent) plus the
                  applicable Margin and (if applicable) any Mandatory Costs; and

         (vi)     each alternative basis so certified shall be binding on the
                  Company and the certifying Bank and treated as part of this
                  Agreement.

15.      INCREASED COSTS

15.1     INCREASED COSTS

         demand by a Finance Party pay that Finance Party the amount of any
         increased cost incurred by it or its Holding Company as a result of:

         (i)   the introduction of, or any change in, or any change in the
               interpretation or application of, any law or regulation after the
               date of this Agreement; or

         currency of a country or reserve asset, special deposit, cash ratio,
         liquidity or capital adequacy requirements or any other form of banking
         or monetary control. Promptly after any Finance Party becomes aware of
         any such increased cost, that Finance Party shall notify the Borrower
         through the Facility Agent. Any demand shall give calculations in
         reasonable detail of that increased cost and the basis for making the
         demand, except that the Finance Party shall not be obliged to disclose
         any information which it reasonably considers to be confidential.

(b)      In this Agreement "INCREASED COST" means:-

         (i)   an additional cost incurred by a Finance Party or its Holding
               Company as a result of the Finance Party having entered into, or

         (ii)  that portion of an additional cost incurred by a Finance Party or
               its Holding Company in the Finance Party making, funding or
               maintaining all or any advances comprised in a class of advances
               formed by or including the participations in the Loans made or to
               be made under this Agreement as is attributable to the Finance
               Party making, funding or maintaining those participations; or

         (iii) a reduction in any amount payable to a Finance Party or its
               Holding Company or the effective return to a Finance Party under
               this Agreement or on its capital or that of its Holding Company;
               or

         (iv)  the amount of any payment made by a Finance Party or its Holding
               Company, or the amount of interest or other return foregone by a
               Finance Party or its Holding Company, calculated by reference to
               any amount received or receivable by a Finance Party from any
               other Party under the Finance Documents.

15.2     EXCEPTIONS

         Clause 15.1 (Increased costs) does not apply to any increased cost:-

         (a)   compensated for by the payment of the Mandatory Costs;

         (b)   compensated for by the operation of Clause 13 (Taxes) or which
               would have been compensated for but for the operation of Clause
               13.4(b) or (d) (Qualifying Bank) or compensated for by the
               operation of any other term of this Agreement;

         (c)   attributable to any change in the rate or the basis of
               calculating tax on the overall net income of a Bank or its
               Holding Company (or the overall net income of a division or
               branch of the Bank or its Holding Company) imposed in the
               jurisdiction in which its principal office or Facility Office is
               situate;

         (d)   attributable to the negligence or wilful default of a Bank; or

         (e)   attributable to the period 90 days after the relevant Finance
               Party becomes aware of the increased cost and prior to the
               Company being notified of an increased cost, except to the extent
               that the increased cost is applied retrospectively; this is
               without prejudice to the right of a Finance Party to claim for
               any subsequent increased cost.

         curtailed by any expropriation or renationalisation by or on behalf of
         any governmental authority.

19.18    SECURITY

         Subject to the registration of the Debenture at Companies House under
         Section 395 of the Companies Act 1985 and the execution of the Deed of
         Release and subject to the qualifications as to matters of law in the
         legal opinion referred to in Schedule 2, the Debenture or any
         Subordination Agreement does not create legal, valid and binding
         obligations on, or is repudiated by, a party to it (other than a
         Finance Party) or for any reason it is alleged by a party to it (other
         than a Finance Party) that it does not create such legal, valid and
         binding obligations of that party.

19.19    MATERIAL ADVERSE CHANGE

         Any event or series of events occurs which, in the reasonable opinion
         of the Majority Banks, has a material adverse effect on the ability of
         the Company to perform its payment obligations under the Finance
         Documents.

19.20    ACCELERATION

         On and at any time after the occurrence of an Event of Default, whilst
         it is continuing the Facility Agent may, and shall if so directed by
         the Majority Banks, by notice to the Company:-

         (a)      cancel the Total Commitments; and/or

         (b)      demand that all or part of the Loans, together with accrued
                  interest, and all other amounts accrued under this Agreement
                  be immediately due and payable, whereupon they shall become
                  immediately due and payable; and/or

         (c)      demand that all or part of the Loans be payable on demand,
                  whereupon they shall immediately become payable on demand by
                  the Facility Agent (acting on the instructions of the Majority
                  Banks).

20.      THE AGENTS AND THE ARRANGERS

20.1     APPOINTMENT AND DUTIES OF THE AGENTS

         Each Finance Party (other than the Agents) irrevocably appoints each
         Agent to act as its agent under and in connection with the Finance
         Documents, and irrevocably authorises each Agent on its behalf to
         perform the duties and to exercise the rights, powers and discretions
         that are specifically delegated to it under or in connection with the
         Finance Documents, together with any other incidental rights, powers
         and discretions. The Agents shall have only those duties which are
         expressly specified in the relevant Finance Documents. Those duties are
         solely of a mechanical and administrative nature.

20.2     ROLE OF THE ARRANGERS

         Except as otherwise provided in this Agreement, neither Arranger has
         any obligations of any kind to any other Party under or in connection
         with any Finance Document.

20.3     RELATIONSHIP

         The relationship between each Agent and the other Finance Parties is
         that of agent and principal only. Nothing in this Agreement constitutes
         an Agent as trustee or fiduciary for any other Party or any other
         person and an Agent need not hold in trust any moneys paid to it for a
         Party or be liable to account for interest on those moneys.

20.4     MAJORITY BANKS' DIRECTIONS

         Each Agent will be fully protected if it acts in accordance with the
         instructions of the Majority Banks in connection with the exercise of
         any right, power or discretion or any matter not expressly provided for
         in the Finance Documents. Any such instructions given by the Majority
         Banks will be binding on all the Banks. In the absence of such
         instructions an Agent may act as it considers to be in the best
         interests of all the Banks.

20.5     DELEGATION

         An Agent may act under the Finance Documents through its personnel and
         agents.

20.6     RESPONSIBILITY FOR DOCUMENTATION

         None of the Agents and the Arrangers is responsible to any other Party
         for:-

         (a)      the execution, genuineness, validity, enforceability or
                  sufficiency of any Finance Document or any other document;

         (b)      the collectability of amounts payable under any Finance
                  Document; or

         (c)      the accuracy of any statements (whether written or oral) made
                  in or in connection with any Finance Document (including the
                  Information Memorandum).
<PAGE>   61
                                       58


20.7     DEFAULT

(a)      Neither Agent is obliged to monitor or enquire as to whether or not a
         Default has occurred. Neither Agent will be deemed to have knowledge of
         the occurrence of a Default. However, if the Facility Agent receives
         notice from a Party referring to this Agreement, describing the Default
         and stating that the event is a Default, it shall promptly notify the
         Banks and the Security Agent.

(b)      An Agent may require from the Banks the receipt of security
         satisfactory to it whether by way of payment in advance or otherwise,
         against any liability or loss which it will or may incur in taking any
         proceedings or action arising out of or in connection with any Finance
         Document before it commences those proceedings or takes that action.

20.8     EXONERATION

(a)      Without limiting paragraph (b) below, neither Agent will be liable to
         any other Party for any action taken or not taken by it under or in
         connection with any Finance Document, unless directly caused by its
         gross negligence or wilful misconduct.

(b)      No Party may take any proceedings against any officer, employee or
         agent of an Agent in respect of any claim it might have against that
         Agent or in respect of any act or omission of any kind (including
         negligence or wilful misconduct) by that officer, employee or agent in
         relation to any Finance Document.

20.9     RELIANCE

         Each Agent may:-

         (a)      rely on any notice or document believed by it to be genuine
                  and correct and to have been signed by, or with the authority
                  of, the proper person;

         (b)      rely on any statement made by a director or employee of any
                  person regarding any matters which may reasonably be assumed
                  to be within his knowledge or within his power to verify; and

         (c)      engage, pay for and rely on legal or other professional
                  advisers selected by it (including those in that Agent's
                  employment and those representing a Party other than that
                  Agent).

20.10    CREDIT APPROVAL AND APPRAISAL

         Without affecting the responsibility of the Company for information
         supplied by it or on its behalf in connection with any Finance
         Document, each Bank confirms that it:-

         (a)      has made its own independent investigation and assessment of
                  the financial condition and affairs of the Company and its
                  related entities in connection with its participation in this
                  Agreement and has not relied exclusively on any information
                  provided to it by an Agent or an Arranger in connection with
                  any Finance Document; and
<PAGE>   62
                                       59


         (b)      will continue to make its own independent appraisal of the
                  creditworthiness of the Company and its related entities while
                  any amount is or may be outstanding under the Finance
                  Documents or any Commitment is in force.

20.11    INFORMATION

(a)      Each Agent shall promptly forward to the person concerned the original
         or a copy of any document which is delivered to that Agent by a Party
         for that person.

(b)      Each Agent shall promptly supply a Bank with a copy of each document
         received by that Agent under Clause 4 (Conditions precedent) (other
         than documents relating to fees) upon the request and at the expense of
         that Bank.

(c)      Except where this Agreement specifically provides otherwise, neither
         Agent is obliged to review or check the accuracy or completeness of any
         document it forwards to another Party.

(d)      Except as provided above, neither Agent has any duty:-

         (i)      either initially or on a continuing basis to provide any Bank
                  with any credit or other information concerning the financial
                  condition or affairs of the Company or any related entity of
                  the Company whether coming into its possession or that of any
                  of its related entities before, on or after the date of this
                  Agreement; or

         (ii)     unless specifically requested to do so by a Bank in accordance
                  with this Agreement, to request any certificates or other
                  documents from the Company.

20.12    THE AGENTS AND THE ARRANGERS INDIVIDUALLY

(a)      If it is also a Bank, each of the Agents and the Arrangers has the same
         rights and powers under the Finance Documents as any other Bank and may
         exercise those rights and powers as though it were not an Agent or an
         Arranger.

(b)      Each of the Agents and the Arrangers may:-

         (i)      carry on any business with the Company or its related
                  entities;

         (ii)     act as agent or trustee for, or in relation to any financing
                  involving, the Company or its related entities; and

         (iii)    retain any profits or remuneration in connection with its
                  activities under this Agreement or in relation to any of the
                  foregoing.

(c)      In acting as an Agent for the Banks, that Agent's agency division shall
         be treated as a separate entity from any other of its divisions or
         departments and, notwithstanding the foregoing provisions of this
         Clause 20, if that Agent should act for any member of the AEL Group in
         any capacity in relation to any other matter, any information given by
         that member of the AEL Group to that Agent in such other capacity may
         be treated as confidential by that Agent.

                                       60


20.13    INDEMNITIES

(a)      Without limiting the liability of the Company under the Finance
         Documents, each Bank shall forthwith on demand indemnify each Agent for
         its proportion of any liability or loss incurred by that Agent in any
         way relating to or arising out of its acting as Agent, except to the
         extent that the liability or loss arises directly from the Agent's
         gross negligence or wilful misconduct.

(b)      A Bank's proportion of the liability or loss set out in paragraph (a)
         above is the proportion which its participation in the Loans (if any)
         bear to all the Loans on the date of the demand. If, however, there are
         no Loans outstanding on the date of demand, then the proportion will be
         the proportion which its Commitment bears to the Total Commitments at
         the date of demand or, if the Total Commitments have been cancelled,
         bore to the Total Commitments immediately before being cancelled.

20.14    COMPLIANCE

(a)      An Agent may refrain from doing anything which might, in its opinion,
         constitute a breach of any law or regulation or be otherwise actionable
         at the suit of any person, and may do anything which, in its opinion,
         is necessary or desirable to comply with any law or regulation of any
         jurisdiction.

(b)      Without limiting paragraph (a) above, an Agent need not disclose any
         information relating to the Company or any of its related entities if
         the disclosure might, in the opinion of that Agent, constitute a breach
         of any law or regulation or any duty of secrecy or confidentiality or
         be otherwise actionable at the suit of any person.

20.15    RESIGNATION OF AGENTS

(a)      Notwithstanding its irrevocable appointment, an Agent may resign by
         giving notice to the Banks and the Company, in which case that Agent
         may forthwith appoint one of its Affiliates as successor Agent or,
         failing that, the Majority Banks may (after consultation with the
         Company) appoint a successor Agent.

(b)      If the appointment of a successor Agent is to be made by the Majority
         Banks but they have not, within 30 days after notice of resignation,
         appointed a successor Agent which accepts the appointment, the retiring
         Agent may appoint a successor Agent.

(c)      The resignation of the retiring Agent and the appointment of any
         successor Agent will both become effective only upon the successor
         Agent notifying all the Parties that it accepts the appointment. On
         giving the notification, the successor Agent will succeed to the
         position of the retiring Agent and the term "FACILITY AGENT" or
         "SECURITY AGENT" will mean the successor Agent (as appropriate).

(d)      The retiring Agent shall, at its own cost, make available to the
         successor Agent such documents and records and provide such assistance
         as the successor Agent may reasonably request for the purposes of
         performing its functions as the relevant Agent under this Agreement.

(e)      Upon its resignation becoming effective, this Clause 20 (The Agents and
         the Arrangers) shall continue to benefit the retiring Agent in respect
         of any action taken or not taken by it under or
<PAGE>   64
                                       61

         in connection with the Finance Documents while it was the relevant
         Agent, and, subject to paragraph (d) above, it shall have no further
         obligation under any Finance Document.

(f)      If so instructed by the Majority Banks, an Agent shall resign in
         accordance with paragraph (a) above. However, in this event that Agent
         may not appoint a successor Agent.

20.16    BANKS

         Each Agent may treat each Bank as a Bank, entitled to payments under
         the Finance Documents and as acting through its Facility Office(s)
         until it has received notice from the Bank to the contrary not less
         than 5 Business Days prior to the relevant payment.

20.17    SECURITY AGENT AS TRUSTEE

(a)      The Security Agent in its capacity as trustee or otherwise under the
         Debenture:-

         (i)      is not liable for any failure, omission or defect in
                  perfecting or registering the security constituted or created
                  by any Finance Document;

         (ii)     may accept without enquiry such title as the Company may have
                  to any asset secured by the Debenture; and

         (iii)    is not under any obligation to hold any Finance Document or
                  any other document in connection with the Finance Documents or
                  the assets secured by any Finance Document (including title
                  deeds) in its own possession or to take any steps to protect
                  or preserve the same. The Security Agent may permit any member
                  of the Group to retain any Finance Document or other document
                  in its possession.

(b)      Save as otherwise provided in the Finance Documents, all moneys which
         under the trusts contained in the Finance Documents are received by an
         Agent in its capacity as trustee or otherwise may be invested in the
         name of or under the control of that Agent in any investment authorised
         by English law for the investment by trustees of trust money or in any
         other investments which may be selected by that Agent. Additionally,
         the same may be placed on deposit in the name of or under the control
         of that Agent at such bank or institution (including that Agent) and
         upon such terms as that Agent may think fit.

         incurred and properly documented by them in connection with:-

         (a)      the syndication, negotiation, preparation, printing and

                  executed after the date of this Agreement; and

         (c)      any amendment, waiver, consent or suspension of rights (or any
                  proposal for any of the foregoing) requested by or on behalf

24.      INDEMNITIES

24.1     CURRENCY INDEMNITY

(a)      If a Finance Party receives an amount in respect of the Company's
         liability under the Finance Documents 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 under the relevant Finance Document:-

         (i)      the Company shall indemnify that Finance Party 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 that Finance Party, 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 shall forthwith on demand

                  currency equal to the deficit; and

         (iii)    the Company shall pay to the Finance Party concerned 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 under the Finance Documents in a currency other than that in
         which it is expressed to be payable.

24.2     OTHER INDEMNITIES

(a)      If:-

         (i)      any payment of principal or an overdue amount is received from
                  any source otherwise than on the last day of a relevant
                  Interest Period or Designated Interest Period (as defined in
                  Clause 9.3 (Default interest)) relative to the amount so

         the Company shall, upon demand by any Bank, pay to the Bank any amounts
         required to compensate such Bank for any additional losses, costs or
         expenses which it may reasonably incur as a result of sub-paragraph (i)
         or (ii) above, including, without limitation, any loss (excluding loss
         of anticipated profits), cost or expense incurred by reason of the
         liquidation or reemployment of deposits or other funds acquired by such
         Bank to fund or maintain any amount payable under the Finance
         Documents.

(b)      The Company agrees, to the fullest extent permitted by law, to
         indemnify and hold harmless each Finance Party and each of their
         respective directors, officers, employees and agents 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


<PAGE>   67
                                       64


         expenses relating to environmental matters) for which any of them may
         become liable or which may be incurred by or asserted against such
         Finance Party or any such director, officer, employee or agent (other
         than by an Agent or another Bank) 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 any
         Finance Document or any transaction in which any proceeds of all or any
         part of the Loans are applied (excluding any such claim, damage,
         liability or expense attributable to the negligence or wilful
         misconduct of such indemnified party).

25.      EVIDENCE AND CALCULATIONS

25.1     ACCOUNTS

         Accounts maintained by a Finance Party in connection with this
         Agreement are prima facie evidence of the matters to which they relate.

25.2     CERTIFICATES AND DETERMINATIONS

         Any certification or determination by a Finance Party of a rate or
         amount under the Finance Documents is prima facie evidence of the
         matters to which it relates. Any determination by a Finance Party of an
         amount under a Finance Document shall contain a calculation of the
         amount in reasonable detail.

25.3     CALCULATIONS

         Interest (including any applicable Mandatory Costs) and the fee payable
         under Clause 21.2 (Commitment fee) accrue from day to day and are
         calculated on the basis of the actual number of days elapsed and a year
         of 365 days or (for interest on Loans in euros or Dollars or if market
         practice otherwise dictates) 360 days.

26.      AMENDMENTS AND WAIVERS

26.1     PROCEDURE

(a)      Subject to Clause 26.2 (Exceptions), any term of the Finance Documents
         may be amended or waived with the agreement of the Company and the
         Majority Banks. The Facility Agent may effect, on behalf of the Banks,
         an amendment to which they or the Majority Banks have agreed.

(b)      The Facility Agent shall promptly notify the other Parties of any
         amendment or waiver effected under paragraph (a) above, and any such
         amendment or waiver shall be binding on all the Parties.

26.2     EXCEPTIONS

(a)      An amendment or waiver which relates to:-

         (i)      the definition of "Majority Banks" in Clause 1.1
                  (Definitions);


<PAGE>   68
                                       65


         (ii)     an extension of the date for, or a decrease in an amount or a
                  change in the currency of, any payment (including the Margin
                  or any other amount of interest or any fee) under the Finance
                  Documents;

         (iii)    an increase in a Bank's Commitment;

         (iv)     a term of a Finance Document which expressly requires the
                  consent of each Bank; or

         (v)      Clause 30 (Pro rata sharing) or this Clause 26 (Amendments and
                  waivers),

         may not be effected without the consent of each Bank.

(b)      An amendment or waiver which relates to the rights and/or obligations
         of an Agent may not be effected without the consent of that Agent.

26.3     WAIVERS AND REMEDIES CUMULATIVE

         The rights of each Party under the Finance Documents:-

         (a)      may be exercised as often as necessary;

         (b)      are cumulative and not exclusive of its rights under the
                  general law; and

         (c)      may be waived only in writing and specifically.

         Delay in exercising or non-exercise of any such right is not a waiver
         of that right.

27.      CHANGES TO THE PARTIES

27.1     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.

27.2     TRANSFERS BY BANKS

(a)      A Bank (the "EXISTING BANK") may at any time assign, transfer or novate
         any of its Commitment and/or rights and/or obligations in whole or in
         part under this Agreement to a Qualifying Bank (the "NEW BANK"). The
         prior consent of the Company is required for any such assignment,
         transfer or novation, unless an Event of Default is outstanding or the
         New Bank is another Bank or an Affiliate of a Bank. However, the prior
         consent of the Company must not be unreasonably withheld or delayed and
         will be deemed to have been given if, within 10 Business Days of
         receipt by the Company of an application for consent, it has not been
         expressly refused.

(b)      A transfer of obligations will be effective only if either:-

         (i)      the obligations are novated in accordance with Clause 27.3
                  (Procedure for novations); or


<PAGE>   69
                                       66


         (ii)     the New Bank confirms to the Facility Agent and the Company
                  that it undertakes to be bound by the terms of the Finance
                  Documents as a Bank in form and substance satisfactory to the
                  Agent. On the transfer becoming effective in this manner the
                  Existing Bank shall be relieved of its obligations under the
                  Finance Documents to the extent that they are transferred to
                  the New Bank.

(c)      Nothing in this Agreement restricts the ability of a Bank to
         sub-contract an obligation if that Bank remains liable under this
         Agreement for that obligation.

(d)      On each occasion an Existing Bank assigns, transfers or novates any of
         its rights and/or obligations under this Agreement, the New Bank shall,
         on the date the assignment, transfer and/or novation takes effect, pay
         to the Facility Agent for its own account a fee of L.1,000.

(e)      An Existing Bank is not responsible to a New Bank for:-

         (i)      the execution, genuineness, validity, enforceability or
                  sufficiency of any Finance Document or any other document;

         (ii)     the collectability of amounts payable under any Finance
                  Document; or

         (iii)    the accuracy of any statements (whether written or oral) made
                  in or in connection with any Finance Document.

(f)      Each New Bank confirms to the Existing Bank and the other Finance 
         Parties that it:-

         (i)      has made its own independent investigation and assessment of
                  the financial condition and affairs of the Company and its
                  related entities in connection with its participation in this
                  Agreement and has not relied exclusively on any information
                  provided to it by the Existing Bank in connection with any
                  Finance Document; and

         (ii)     will continue to make its own independent appraisal of the
                  creditworthiness of the Company and its related entities while
                  any amount is or may be outstanding under this Agreement or
                  any Commitment is in force.

(g)      Nothing in any Finance Document obliges an Existing Bank to:-

         (i)      accept a re-transfer from a New Bank of any of the rights
                  and/or obligations assigned, transferred or novated under this
                  Clause 27; or

         (ii)     support any losses incurred by the New Bank by reason of the
                  non-performance by the Company of its obligations under the
                  Finance Documents or otherwise.

(h)      Any reference in this Agreement to a Bank includes a New Bank, but
         excludes a Bank if no amount is or may be owed to or by that Bank under
         this Agreement and its Commitment has been cancelled or reduced to nil.

27.3     PROCEDURE FOR NOVATIONS

(a)      A novation is effected if:-


<PAGE>   70
                                       67


         (i)      the Existing Bank and the New Bank deliver to the Facility
                  Agent a duly completed certificate, substantially in the form
                  of Schedule 5 (a "NOVATION CERTIFICATE"); and

         (ii)     the Facility Agent executes it.

(b)      Each Party (other than the Existing Bank and the New Bank) irrevocably
         authorises the Facility Agent to execute any duly completed Novation
         Certificate on its behalf.

(c)      To the extent that they are expressed to be the subject of the novation
         in the Novation Certificate:-

         (i)      the Existing Bank and the other Parties (the "EXISTING
                  PARTIES") will be released from their obligations to each
                  other (the "DISCHARGED OBLIGATIONS");

         (ii)     the New Bank and the existing Parties will assume obligations
                  towards each other which differ from the discharged
                  obligations only insofar as they are owed to or assumed by the
                  New Bank instead of the Existing Bank;

         (iii)    the rights of the Existing Bank against the existing Parties
                  and vice versa (the "DISCHARGED RIGHTS") will be cancelled;
                  and

         (iv)     the New Bank and the existing Parties will acquire rights
                  against each other which differ from the discharged rights
                  only insofar as they are exercisable by or against the New
                  Bank instead of the Existing Bank,

         all on the date of execution of the Novation Certificate by the
         Facility Agent or, if later, the date specified in the Novation
         Certificate.

27.4     REFERENCE BANKS

         If a Reference Bank (or, if a Reference Bank is not a Bank, the Bank of
         which it is an Affiliate) ceases to be one of the Banks, the Facility
         Agent shall (in consultation with the Company) appoint another Bank or
         an Affiliate of a Bank to replace that Reference Bank.

27.5     INCREASED COSTS ETC.

         If:-

         (a)      a Bank assigns, transfers or novates any of its Commitment
                  and/or rights and/or obligations under the Finance Documents
                  or changes its Facility Office; and

         (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 New Bank or Bank
                  acting through its new Facility Office under Clause 13 (Taxes)
                  or Clause 15 (Increased costs),

         then, notwithstanding the provisions of Clause 13 (Taxes) or Clause 15
         (Increased costs), the relevant New Bank or Bank acting through its new
         Facility Office is only entitled to receive payment under those Clauses
         from the Company to the same extent as the relevant Existing 

<PAGE>   71
                                       68


         Bank or Bank acting through its previous Facility Office would have
         been if the assignment, transfer, novation or change had not occurred.

27.6     REGISTER

         The Facility Agent shall keep a register of all the Parties and shall
         supply any other Party (at that Party's expense) with a copy of the
         register on request.

28.      DISCLOSURE OF INFORMATION

(a)      A Finance Party may disclose to one of its Affiliates or any person (a
         "PARTICIPANT") with whom it is proposing to enter, or has entered into,
         any kind of transfer, participation or other agreement in relation to
         this Agreement:-

         (i)      a copy of any Finance Document; and

         (ii)     any information which that Finance Party has acquired under or
                  in connection with any Finance Document,

         so long as disclosure of confidential information under sub-paragraph
         (ii) above may only be disclosed to a participant if the participant
         has agreed in writing with the relevant Finance Party to keep the
         information confidential on the same terms (with consequential changes)
         as are set out in paragraph (b) below.

(b)      Each Finance Party shall keep confidential and not, without the prior
         consent of the Company, use any information (other than information
         which is publicly available other than as a result of a breach of this
         paragraph (b)) supplied by or on behalf of the Company under the
         Finance Documents otherwise than in connection with the Finance
         Documents. However, each Finance Party is entitled to disclose
         information:

         (i)      in connection with any legal or arbitration proceedings
                  arising out of or in connection with a Finance Document; or

         (ii)     if required to do so by an order of a court of competent
                  jurisdiction whether under any procedure for discovering
                  documents or otherwise; or

         (iii)    pursuant to any law or regulation in accordance with which
                  that Bank is required or accustomed to act; or

         (iv)     to a governmental, banking, taxation or other regulatory
                  authority of any competent jurisdiction; or

         (v)      to its accountants or legal advisers or any other professional
                  advisers.

29.      SET-OFF

         If an Event of Default is outstanding, a Finance Party may set off any
         matured obligation owed by the Company under the Finance Documents (to
         the extent beneficially owned by that Finance Party) against any
         obligation (whether or not matured) owed by that Finance Party to the
         Company, regardless of the place of payment, booking branch or currency
         of either obligation. If the obligations are in different currencies,
         the Finance Party may convert either 


<PAGE>   72
                                       69


         obligation at a market rate of exchange in its usual course of business
         for the purpose of the set-off. If either obligation is unliquidated or
         unascertained, the Finance Party may set off in an amount estimated by
         it in good faith to be the amount of that obligation. Nothing in this
         Clause 29 will be effective to create a charge.

30.      PRO RATA SHARING

30.1     REDISTRIBUTION

         If any amount owing by the Company under this Agreement to a Finance
         Party (the "RECOVERING FINANCE PARTY") is discharged by payment,
         set-off or any other manner other than through the relevant Agent in
         accordance with Clause 12 (Payments) (a "RECOVERY"), then:-

         (a)      the recovering Finance Party shall, within 3 Business Days,
                  notify details of the recovery to the Facility Agent;

         (b)      the Facility Agent shall determine whether the recovery is in
                  excess of the amount which the recovering Finance Party would
                  have received had the recovery been received by the Facility
                  Agent and distributed in accordance with Clause 12 (Payments);

         (c)      subject to Clause 30.3 (Exceptions), the recovering Finance
                  Party shall, within 3 Business Days of demand by the Facility
                  Agent, pay to the Facility Agent an amount (the
                  "REDISTRIBUTION") equal to the excess;

         (d)      the Facility Agent shall treat the redistribution as if it
                  were a payment by the Company under Clause 12 (Payments) and
                  shall pay the redistribution to the Finance Parties (other
                  than the recovering Finance Party) in accordance with Clause
                  12.7 (Partial payments); and

         (e)      after payment of the full redistribution, the recovering
                  Finance Party will be subrogated to the portion of the claims
                  paid under paragraph (d) above, and the Company will owe the
                  recovering Finance Party a debt which is equal to the
                  redistribution, immediately payable and of the type originally
                  discharged.

30.2     REVERSAL OF REDISTRIBUTION

         If under Clause 30.1 (Redistribution):-

         (a)      a recovering Finance Party must subsequently return a
                  recovery, or an amount measured by reference to a recovery, to
                  the Company; and

         (b)      the recovering Finance Party has paid a redistribution in
                  relation to that recovery,

         each Finance Party shall, within 3 Business Days of demand by the
         recovering Finance Party through the Facility Agent, reimburse the
         recovering Finance Party all or the appropriate portion of the
         redistribution paid to that Finance Party. Thereupon, the subrogation
         in Clause 30.1(e) (Redistribution) will operate in reverse to the
         extent of the reimbursement.


<PAGE>   73
                                       70


30.3     EXCEPTIONS

(a)      A recovering Finance Party need not pay a redistribution to the extent
         that it would not, after the payment, have a valid claim against the
         Company in the amount of the redistribution pursuant to Clause 30.1(e)
         (Redistribution).

(b)      A recovering Finance Party is not obliged to share with any other
         Finance Party any amount which the recovering Finance Party has
         received or recovered as a result of taking legal proceedings, if that
         other Finance Party had an opportunity to participate in those legal
         proceedings, but did not do so and did not take separate legal
         proceedings.

31.      SEVERABILITY

         If a provision of any Finance Document 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 the Finance Documents; or

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

32.      COUNTERPARTS

         A Finance Document may be executed in any number of counterparts, and
         this has the same effect as if the signatures on the counterparts were
         on a single copy of the Finance Document.

33.      NOTICES

33.1     GIVING OF NOTICES

         All notices or other communications under or in connection with the

                                   SCHEDULE 3

                       CALCULATION OF THE MANDATORY COSTS

(a)      The Mandatory Costs for a Loan for its Interest Period(s) is the rate
         calculated by the Facility Agent in accordance with the following
         formula:

         For a Loan in Sterling:

         BY + S(Y-Z) + F x 0.01% per annum = Mandatory Costs
         -----------------------
            100-(B + S)

         For a Loan in an Optional Currency:

         F x 0.01% per annum = Mandatory Costs
         ---------
           300

         where on the day of application of the formula:

         B        is the percentage of the Facility Agent's eligible liabilities
                  (in excess of any stated minimum) which the Bank of England
                  requires the Facility Agent to hold on a non-interest-bearing
                  deposit account in accordance with its cash ratio
                  requirements;

         Y        is LIBOR for the relevant Interest Period of that Loan;

         S        is the percentage of the Facility Agent's eligible liabilities
                  which the Bank of England requires the Facility Agent to place
                  as a special deposit;

         Z        is the interest rate per annum allowed by the Bank of England
                  on special deposits; and

         F        is the charge payable by the Facility Agent to the Financial
                  Services Authority under the relevant paragraph of the Fees
                  Regulations expressed in pounds per L.1 million of the
                  Fee base of the Facility Agent.

(b)      For the purposes of this Schedule 3:

         (i)      "ELIGIBLE LIABILITIES" and "SPECIAL DEPOSITS" have the
                  meanings given to them at the time of application of the
                  formula by the Bank of England;

         (ii)     "FEE BASE" has the meaning given to it in the Fees
                  Regulations; and

         (iii)    "FEES REGULATIONS" means the Banking Supervision (Fees)
                  Regulations 1998 or any regulations governing the payment of
                  fees for banking supervision.

(c)      In the application of the formula, B, Y, S and Z are included in the
         formula as figures and not as percentages, e.g. if B = 0.5% and Y =
         15%, BY is calculated as 0.5 x 15.

(d)      (i)      The formula is applied on the first day of the relevant 
                  Interest Period.


<PAGE>   79
                                       76


         (ii)     Each rate calculated in accordance with the formula is, if
                  necessary, rounded upward to the nearest four decimal places.

(e)      If the Facility Agent determines that a change in circumstances has
         rendered, or will render, the formula inappropriate, the Facility Agent
         (after consultation with the Company) shall notify the Company of the
         manner in which the Mandatory Costs will subsequently be calculated.
         The manner of calculation so notified by the Facility Agent shall, in
         the absence of manifest error, be binding on all the Parties.

         1925 shall not apply to the security constituted by this Deed.

         After the security constituted by this Deed has become enforceable, the
         Security Agent may on giving notice to the Chargor, exercise (in the
         name of the Chargor and without any further consent or authority on the
         part of the Chargor) any voting rights and any powers or rights which
         may be exercised by the person or persons in whose name any Share and
         its Related Rights are registered or who is the holder of any of them
         or otherwise (including all the powers given to trustees by Section
         10(3) and (4) of the Trustee Act, 1925 as amended by Section 9 of the

         Security Account.

         default or omission for which a mortgagee in possession might be
         liable.

8.5      SECURITY AGENT OF THE CHARGOR

         Each Receiver is deemed to be the agent of the Chargor for all purposes
         and accordingly is deemed to be in the same position as a Receiver duly
         appointed by a mortgagee under the Law of Property Act 1925. The
         Chargor alone shall be responsible for his contracts, engagements,
         acts, omissions, defaults and losses and for liabilities incurred by
         him and no Finance Party shall incur any liability (either to the

                  purporting to exercise has become exercisable; or

         (c)      whether any money remains due under the Finance Documents; or

                  to be applied.

         At any time after the security constituted by this Deed has become
         enforceable, the Security Agent may:-

                  and/or

                  and/or

         (c)      settle and pass the accounts of the prior mortgagee, chargee
                  or encumbrancer; any accounts so settled and passed shall be
                  conclusive and binding on the Chargor.

         All principal moneys, interest, costs, charges and expenses of and

         persons to be a Receiver of all or any part of the Security Assets in
         like manner in every respect as if the Security Agent had become

         sale conferred under the Law of Property Act 1925.

9.2      REMOVAL

                  regardless of the place of payment, booking branch or currency

         (b)      debit any account of the Chargor (whether sole or joint) with
                  the Security Agent at any of its offices anywhere (including
                  an account opened specially for that purpose) with all or any
                  part of the Secured Liabilities; and/or

         (c)      apply any moneys in a Security Account in or towards the
                  payment or discharge of the Secured Liabilities.

12.      APPLICATION OF PROCEEDS

         Any moneys received by the Security Agent or any Receiver after this

         recover any shortfall from the Chargor):

         (a)      in satisfaction of or provision for all costs and expenses
                  incurred by the Security Agent or any Receiver and of all
                  remuneration due to the Receiver under this Deed;

                  of them as is then due and payable; and

13.      EXPENSES AND INDEMNITY

         The Chargor shall forthwith on demand pay all costs and expenses
         (including legal fees) properly and (before any enforcement of the
         security constituted by this Deed) reasonably incurred and, in each
         case, properly documented in connection with this Deed by any Finance
         Party, Receiver, attorney, manager, agent or other person appointed by
         the Security Agent under this Deed, and keep each of them indemnified
         against any failure or delay in paying the same.

14.      DELEGATION

         The Security Agent and any Receiver may delegate by power of attorney
         or in any other manner to any person any right, power or discretion
         exercisable by them under this Deed. Any such delegation may be made
         upon the terms (including power to sub-delegate) and subject to any
         regulations which the Security Agent or that Receiver (as the case may
         be) may think fit. Neither the Security Agent nor any Receiver will be
         in any way liable or responsible to the Chargor for any loss or
         liability arising from any act, default, omission or misconduct on the
         part of any such delegate or sub-delegate.

15.      FURTHER ASSURANCES

         The Chargor shall, at its own expense, take whatever action the
         Security Agent or a Receiver may reasonably require for:-

         (a)      perfecting or protecting the security intended to be created
                  by this Deed over any Security Asset;

         (b)      facilitating the realisation of any Security Asset, or the
                  exercise of any right, power or discretion exercisable, by the
                  Security Agent or any Receiver or any of its or their
                  delegates or sub-delegates in respect of any Security Asset,

         including the execution of any transfer, conveyance, assignment or
         assurance of any property whether to the Security Agent or to its
         nominees, and the giving of any notice, order or direction and the
         making of any registration, which, in any such case, the Security Agent
         may think expedient but excluding, unless a notice under Clause 19.20
         (Acceleration) of the Credit Agreement has been given, any action to
         claim, demand or collect any book or other debts of the Chargor.

16.      POWER OF ATTORNEY

         The Chargor, by way of security, irrevocably and severally appoints the
         Security Agent, each Receiver and any of their delegates or
         sub-delegates to be its attorney to take any action which the Chargor
         is obliged to take under this Deed, including under Clause 15 (Further
         assurances). The Chargor ratifies and confirms whatever any attorney
         does or purports to do pursuant to its appointment under this Clause.

17.      MISCELLANEOUS

17.1     COVENANT TO PAY

         The Chargor shall pay or discharge the Secured Liabilities in the
         manner provided for in the Finance Documents.

17.2     CONTINUING SECURITY

         The security constituted by this Deed is continuing and will extend to
         the ultimate balance of all the Secured Liabilities, regardless of any
         intermediate payment or discharge in whole or in part.

17.3     ADDITIONAL SECURITY

         The security constituted by this Deed is in addition to and is not in
         any way prejudiced by any other security now or subsequently held by
         any Finance Party for any Secured Liability.

17.4     TACKING

         Each Bank shall perform its obligations under the Credit Agreement
         (including any obligation to make available further advances).

17.5     NEW ACCOUNTS

         If a Finance Party receives, or is deemed to be affected by, notice,
         whether actual or constructive, of any subsequent charge or other
         interest affecting any Security Asset and/or the proceeds of sale of
         any Security Asset, the Finance Party may open a new account for the
         Chargor. If the Finance Party does not open a new account, it shall
         nevertheless be treated as if it had done so at the time when it
         received or was deemed to have received notice. As from that time all
         payments made to the Finance Party will be credited or be treated as
         having been credited to the new account and will not operate to reduce
         any amount for which this Deed is security.

17.6     TIME DEPOSITS

         Without prejudice to any right of set-off any Finance Party may have
         under any other Finance Document or otherwise, if any time deposit
         matures on any account the Chargor has with any Finance Party at a time
         within the Security Period when:

         (a)      this security has become enforceable; and

         (b)      no amount of the Secured Liabilities is due and payable,

         that time deposit shall automatically be renewed for any further
         maturity which that Finance Party considers appropriate.

18.      RELEASE AND CONFIRMATION

(a)      Upon the expiry of the Security Period (but not otherwise), the Finance
         Parties shall, at the request and cost of the Chargor, take whatever
         action is necessary to release the Security Assets from the security
         constituted by this Deed including any re-assignment of security.

(b)      The Security Agent shall act in accordance with the terms of the Credit
         Agreement in issuing instructions to the Account Bank in accordance
         with the notice to that Account Bank and shall give an appropriate
         notice to each Account Bank on repayment in full of the Secured
         Liabilities.

                     FORM OF LEGAL OPINIONS OF ALLEN & OVERY


To:      The Finance Parties
         (as defined in the
         Credit Agreement defined below).


Dear Sirs,

       AZURIX EUROPE LTD. (THE "COMPANY") - L.425,000,000 CREDIT AGREEMENT
                DATED [        ], 1999 (THE "CREDIT AGREEMENT")


We have received instructions from and participated in discussions with the
Arrangers in connection with the Credit Agreement.

Terms defined in the Credit Agreement have the same meaning in this opinion. The
Credit Agreement, the Subordination Deed and the Debenture (as defined below) is
each called an "AGREEMENT". "SECURITY ASSETS" has, in relation to the Debenture,
the meaning given to it in the Debenture

For the purposes of this opinion we have examined the following documents:-

(a)      a signed copy of the Credit Agreement;

(b)      an executed copy of the Debenture dated [   ], 1999 between the Company
         and the Security Agent (the "DEBENTURE");

(c)      a certified copy of the memorandum and articles of association and
         certificate of incorporation of the Company;

(d)      a certified copy of the minutes of a meeting of the board of directors
         of the Company dated [ ], 1999; and

(e)      an executed copy of the Subordination Deed between Wessex Water Limited
         ("WESSEX"), the Company and the Facility Agent dated [ ], 1999.

On [ ], 1999, we carried out a search of the Company and Wessex at the Companies
Registry. On [ ], 1999 we made a telephone search of the Company and Wessex at
the winding-up petitions at the Companies court.

The above are the only documents or records we have examined, and the only
searches and enquiries we have carried out, for the purposes of this opinion.



<PAGE>   102
                                       99


We assume that:-

(i)      each of Wessex and the Company is not unable to pay its debts within
         the meaning of section 123 of the Insolvency Act, 1986 at the time it
         enters into an Agreement and will not as a consequence of either
         Agreement be unable to pay its debts within the meaning of that
         section;

(ii)     no step has been taken to wind up the Company or Wessex or appoint a
         receiver in respect of it or any of its assets, although the searches
         referred to above give no indication that any winding-up order or
         appointment of a receiver has been made;

(iii)    all signatures and documents are genuine;

(iv)     all documents are and remain up-to-date;

(v)      the correct procedure was carried out at the board meeting referred to
         in paragraph (d) above; for example, there was a valid quorum, all
         relevant interests of directors were declared and the resolutions were
         duly passed at the meeting; and

(vi)     each Agreement is a legally binding, valid and enforceable obligation
         of each party to it other than the Company and Wessex.

Subject to the qualifications set out below and to any matters not disclosed to
us, it is our opinion that, so far as the present laws of England are
concerned:-

(1)      STATUS: Each of Wessex and the Company is a company incorporated with
         limited liability under the laws of England and is not in liquidation.

(2)      POWERS AND AUTHORITY: Each of Wessex and the Company has the corporate
         power to enter into and perform the Agreements to which it is a party
         and has taken all necessary corporate action to authorise the
         execution, delivery and performance of the Agreements to which it is a
         party.

(3)      LEGAL VALIDITY: Each Agreement to which it is a party constitutes the
         Company's and/or Wessex's legally binding, valid and enforceable
         obligation.

(4)      NON-CONFLICT: The execution, delivery and performance by the Company
         and Wessex of each Agreement to which it is a party will not violate
         any provision of (i) any existing English law applicable to companies
         generally, or (ii) the memorandum or articles of association of the
         Company and Wessex.

(5)      CONSENTS: No authorizations of governmental, judicial or public bodies
         or authorities in England are required by the Company or Wessex in
         connection with the performance, validity or enforceability of an
         Agreement to which it is a party.

(6)      TAXES: All payments due from the Company under the Credit Agreement may
         be made without deduction of any United Kingdom taxes, if, in the case
         of any interest:

         (a)      the person which made the part of the Loan to which the
                  interest relates was, at the time of the making of the Loan, a
                  "bank" as defined in section 840A of the Income 


<PAGE>   103
                                      100


                  and Corporation Taxes Act 1988 is beneficially entitled to
                  that interest and the recipient of the interest is within the
                  charge to United Kingdom corporation tax as regards that
                  interest; or

         (b)      (i)      the person that made the part of the Loan to
                           which the interest relates is a resident (as defined
                           in the appropriate Double Taxation treaty) in a
                           country with which the United Kingdom has a Double
                           Taxation treaty giving residents of that country
                           exemption from United Kingdom taxation on interest
                           and does not carry on business in the United Kingdom
                           through a permanent establishment with which its
                           participation in the Loan is effectively connected;
                           and

                  (ii)     the Company has received an appropriate exemption
                           notice (or similar document) from HM Inland Revenue.


(7)      REGISTRATION REQUIREMENTS: Except for due registration of the Debenture
         and the Subordination Deed, it is not necessary or advisable to file,
         register or record either Agreement in any public place or elsewhere in
         England.

(8)      STAMP DUTIES: No stamp, registration or similar tax or charge is
         payable in England in respect of either Agreement.

(9)      SECURITY: Subject to due registration where required, the Debenture
         creates security interests in the Security Assets concerned.

This opinion is subject to the following qualifications:-

(i)      This opinion is subject to all insolvency and other laws affecting the
         rights of creditors or secured creditors generally.

(ii)     No opinion is expressed on matters of fact.

(iii)    We assume that no foreign law affects the conclusions stated above.

(iv)     No opinion is expressed as to:

         (a)      the title of the Company to any Security Asset; or

         (b)      the priority of any security created or to be created by the
                  Debenture; or

         (c)      the nature of the security created by the Debenture (whether
                  fixed or floating); or

         (d)      the marketability of, or rights of enforcement over, the
                  Security Assets.

         These matters are too lengthy to cover in this letter.

(v)      The term "enforceable" means that a document is of a type and form
         enforced by the English courts. It does not mean that each obligation
         will be enforced in accordance with its terms. Certain rights and
         obligations may be qualified by the non-conclusivity of certificates,

         doctrines of good faith and fair conduct, the availability of equitable
         remedies and other matters, but in our view these qualifications would
         not defeat your legitimate expectations in any material respect.

This opinion is given for the sole benefit of the Finance Parties as at the date
of the Credit Agreement and may not be relied upon by or disclosed to any other
person.

Yours faithfully

<PAGE>   110
                                      107


         (a)      the Junior Creditor receives a payment or distribution in

                  other source; or

                  of any security or any guarantee, indemnity or other assurance
                  against financial loss for any Junior Debt; or

         (c)      the Company makes any payment or distribution to the Junior
                  Creditor on account of the purchase or other acquisition of
                  any of the Junior Debt,

         the Junior Creditor will hold the same in trust for the Finance Parties
         and pay and distribute it to the Facility Agent for application towards
         the Senior Debt until the Senior Debt is irrevocably paid in full.

4.2      NON-PERMITTED SET-OFFS

         Debt is discharged by set-off, the Junior Creditor will promptly pay an

         towards the Senior Debt until the Senior Debt is irrevocably paid in
         full.

4.3      FAILURE OF TRUST

         If, for any reason, a trust in favour of, or a holding of property for,
         the Finance Parties under this Deed is invalid or unenforceable, the
         Junior Creditor will pay and deliver to the Facility Agent an amount
         equal to the payment, receipt or recovery which the Junior Creditor
         would otherwise have been bound to hold on trust for or as property of
         the Finance Parties.

5.       SUBORDINATION ON INSOLVENCY

         If any of the events set out in Clauses 19.6 (Insolvency) to 19.10

         (a)      the Junior Debt will be subordinate in right of payment to the
                  Senior Debt;

         (b)      the Facility Agent may, and is irrevocably authorised on
                  behalf of the Junior Creditor to, (i) claim, enforce and prove
                  for the Junior Debt, (ii) file claims and proofs, give
                  receipts and take all such proceedings and do all such things
                  as the Facility Agent reasonably sees fit to recover the
                  Junior Debt and (iii) receive all distributions on the Junior
                  Debt for application towards the Senior Debt;

         (c)      if and to the extent that the Facility Agent is not entitled
                  to do any of the foregoing, the Junior Creditor will do so in
                  good time as reasonably directed by the Facility Agent;

         (d)      the Junior Creditor will hold all distributions in cash or in
                  kind received or receivable by it in respect of the Junior
                  Debt from the Company or from any other source in trust for
                  the Finance Parties and will (at the Junior Creditor's
                  expense) pay and transfer the same to the Facility Agent for
                  application towards the Senior Debt until the Senior Debt is
                  irrevocably paid in full; and


<PAGE>   111
                                      108


         (e)      the trustee in bankruptcy, liquidator, assignee or other
                  person distributing the assets of the Company or their
                  proceeds is directed to pay distributions on the Junior Debt
                  direct to the Facility Agent for application towards the
                  Senior Debt until the Senior Debt is irrevocably paid in full.
                  The Junior Creditor will give all such notices and do all such
                  things as the Facility Agent may reasonably direct to give
                  effect to this provision.

6.       CONSENTS

         The Junior Creditor will not have any remedy against the Company, the
         Facility Agent or the Finance Parties by reason of any transaction
         entered into between the Facility Agent and/or the Finance Parties and
         the Company which violates any Junior Finance Document and the Junior
         Creditor may not object to any such transaction by reason of any
         provisions of the Junior Finance Documents.

7.       REPRESENTATIONS AND WARRANTIES

         The Junior Creditor represents and warrants to the Facility Agent and

         (a)      is within its powers and has been duly authorised by it;

         (b)      subject to qualifications on to matters of law in the legal

                  legal, valid, binding and enforceable obligations; and

         (c)      does not conflict with any law or regulation or its
                  constitutional documents or, to any material extent, any
                  document binding on it and that it has obtained all necessary
                  consents for its performance of this Deed.

8.       PROTECTION OF SUBORDINATION

8.1      CONTINUING SUBORDINATION

         The subordination provisions in this Deed constitute a continuing
         subordination and benefit the ultimate balance of the Senior Debt
         regardless of any intermediate payment or discharge of the Senior Debt
         in whole or in part.

8.2      WAIVER OF DEFENCES

         The subordination in this Deed and the obligations of the Junior
         Creditor under this Deed will not be affected by any act, omission,
         matter or thing which, but for this provision, would reduce, release or
         prejudice the subordination or any of those obligations in whole or in
         part, including without limitation:

         (a)      any waiver granted to, or composition with, the Company or
                  other person;

                  Company or other person in respect of the Senior Debt or

                                      109


         (c)      any unenforceability, illegality or invalidity of any
                  obligation of the Company or security in respect of the Senior
                  Debt or any other document or security.

8.3      IMMEDIATE RECOURSE

         The Junior Creditor waives any right it may have of first requiring any
         Finance Party (or the Facility Agent or any trustee or other agent on
         its behalf) to proceed against or enforce any other rights or security
         or claim payment from any person before claiming the benefit of this
         Deed. The Facility Agent may refrain from applying or enforcing any

         payment by notice in writing to be received by the other party before
         the date when the relevant payment is to be made.

         without any deduction or withholding (whether in respect of set-off,
         counterclaim, duties, taxes, charges or otherwise howsoever) provided
         that if the Borrower is required by law to make any such deduction or
         withholding, it shall:

         3.3.1    ensure that the deduction or withholding does not exceed the
                  minimum amount legally required;

         3.3.2    pay to the relevant taxation or other authorities, as
                  appropriate, the full amount of the deduction or withholding;

         same calendar month (if there is one) or the preceding Business Day (if
         there is not).

3.5      Payments received by the Lender from the Borrower shall be applied
         firstly against outstanding amounts of interest, and then against the

         outstanding under this Agreement.

4.       GUARANTEE

4.1      The Guarantor unconditionally and irrevocably guarantees that, if for
         any reason the Borrower does not pay any sum payable by it under this
         Agreement by the time, on the date and otherwise in the manner
         specified in this Agreement (whether on the normal due date, on
         acceleration or otherwise), the Guarantor will pay that sum before

                  winding-up or

         4.2.7    the illegality, invalidity or unenforceability of, or any
                  defect in, any provision of this Agreement or any security or
                  other guarantee or any of the obligations of any of the
                  parties under or in connection with this Agreement or any
                  security or other guarantee).

4.3      The Guarantor's obligations under this Agreement are and will remain in
         full force and effect by way of continuing security until no sum
         remains to be lent under this Agreement and the Lender has irrevocably
         received or recovered all sums payable under this Agreement.
         Furthermore, those obligations of the Guarantor are additional to, and
         not instead of, any security or other guarantee at any time existing in
         favour of any person, whether from the Guarantor or otherwise, and may
         be enforced without first having recourse to the Borrower, any other
         person, any security or any other guarantee. The Guarantor irrevocably
         waives all notices and demands of any kind.

4.4.     So long as any sum remains to be lent or remains payable under this
         Agreement:

         4.4.1    any right of the Guarantor, by reason of the performance of
                  any of its obligations under this Clause 4, to be indemnified
                  by the Borrower, to prove in respect of any liability in the
                  bankruptcy or winding-up of the Borrower or to take the
                  benefit of or enforce any security or other Guarantee shall
                  (and shall only) be exercised and enforced in such manner and
                  on such terms as the Lender may require and

         4.4.2    any amount received or recovered by the Guarantor (a) as a
                  result of any exercise of any such right or (b) in the
                  bankruptcy or winding-up of the Borrower shall be held in
                  trust for, and immediately paid to, the Lender.

4.5      The Guarantor shall on demand indemnify the Lender against any funding
         or other cost, loss, expense or liability (including loss of margin)
         sustained or incurred by the Lender as a result of it being required
         for any reason (including any bankruptcy, insolvency, winding-up or
         similar law of any jurisdiction) to refund all or part of any amount
         received or recovered by it 


<PAGE>   122
                                      119


         in respect of any sum payable by the Borrower under this Agreement and
         shall in any event pay to the Lender on demand the amount so refunded
         by it.

4.6      For the purpose of enabling the Lender to maximise its recoveries in
         actual or potential insolvency, any amount received or recovered by the
         Lender (otherwise than as a result of a payment by the Lender) in
         respect of any sum payable by the Borrower under this Agreement may be
         placed by the recipient in an interest bearing suspense account. That
         amount may be kept there (with any interest earned being credited to
         that account) unless and until the recipient is satisfied that it is
         not obliged to pay any further sum under this Agreement and that it has
         irrevocably received or recovered its share of the Advances, all
         interest accrued thereon and any other sums payable to it under this
         Agreement.

4.7      As separate, independent and alternative stipulations, the Guarantor
         unconditionally and irrevocably agrees:

         4.7.1    that any sum which, although expressed to be payable by the
                  Borrower under this Agreement, is for any reason (whether or
                  not now existing and whether or not now known or becoming
                  known to any party to this Agreement) not recoverable from the
                  Guarantor on the basis of a guarantee shall nevertheless be
                  recoverable from it as if it were the sole principal debtor
                  and shall be paid by it to the Lender on demand and

         4.7.2    as a primary obligation to indemnify the Lender against any
                  loss suffered by it as a result of any sum expressed to be
                  payable by the Borrower under this Agreement not being paid by
                  the time, on the date and otherwise in the manner specified in
                  this Agreement or any payment obligation of the Borrower under
                  this Agreement being or becoming void, voidable or
                  unenforceable for any reason (whether or not now existing and
                  whether or not now known or becoming known to any party to
                  this Agreement), the amount of that loss being the amount
                  expressed to be payable by the Borrower in respect of the
                  relevant sum.

5.       REPRESENTATIONS AND WARRANTIES

5.1      Each of the Borrower and the Guarantor severally represents and
         warrants to and for the benefit of the Lender that this Agreement:

         5.1.2    constitutes its legal, valid, binding and enforceable
                  obligations; and

6.1      If any of the following occurs

         6.1.1    the Borrower does not pay or otherwise satisfy on the due date
                  any amount payable by it under this Agreement and the
                  non-payment continues unremedied for 5 Business Days from the
                  receipt of it by notice of non-payment from the Lender;


<PAGE>   123
                                      120


         6.1.2    the Borrower or the Guarantor is, or is deemed for the
                  purposes of any law (but for this purpose Section 123(l)(a) of
                  the Insolvency Act 1986 will take effect as if for L.750
                  THEre was substituted "L.5,000,000") to be, unable to pay
                  its debts as they fall due or TO be insolvent, or admits
                  inability to pay its debts as they fall due;

         6.1.3    any step (including petition, proposal or convening a meeting)
                  is taken, as a result of financial difficulties, with a view
                  to a composition, assignment or arrangement with any creditors
                  of the Borrower or Guarantor;

         6.1.4    any person presents a petition for the bankruptcy or
                  winding-up or for the administration of the Borrower or
                  Guarantor, and, in the case of a petition for bankruptcy or
                  winding-up presented by a creditor, it is not withdrawn,
                  discharged or stayed within 21 days;

                  administration of the Borrower or Guarantor;

         6.1.6    any liquidator, trustee in bankruptcy, judicial custodian,
                  compulsory manager, receiver, administrative receiver,
                  administrator or the like is appointed in respect of the
                  Borrower or Guarantor or any part of their respective assets;

         6.1.7    there occurs, in relation to the Borrower or Guarantor, any
                  event anywhere which, in the opinion of the Lender, appears to
                  correspond with any of those mentioned in sub-Clauses 6.1.2 to
                  6.1.6 inclusive;

                  perform any of its material obligations under this Agreement;

         6.1.9    the guarantee of the Guarantor in Clause 4 is not (or is
                  claimed by the Borrower or Guarantor not to be) in full force
                  and effect;

         6.1.10   the Borrower incurs any [Financial Indebtedness] [other 
                  than     ] which is not effectively subordinated to its 
                  payment obligations under this Agreement;

         6.1.11   the Agent validly gives notice to the Company pursuant to
                  Clause      [acceleration] of the Credit Agreement;

         then the Lender may serve on the Borrower a notice declaring that any
         and all of the obligations of the Lender hereunder shall be cancelled
         whereupon the same shall be so cancelled forthwith and that all amounts
         outstanding under this Agreement from the Borrower to the Lender shall
         become immediately due and payable whereupon they shall become so due
         and payable.

7.       ILLEGALITY

7.1      If any change in or introduction of any applicable law, regulation or
         treaty, or any change in the interpretation or application thereof,
         shall make it unlawful hereunder for the Lender to make available or
         fund or maintain the loan to be made under this Agreement, as the case
         may require, the Lender shall give notice thereof to the Borrower,
         whereupon the Borrower 


<PAGE>   124
                                      121


         shall repay all amounts outstanding under this Agreement together with
         accrued interest thereon and any other amounts payable to the Lender
         hereunder within such period as may be permitted by such law,
         regulation or treaty, or the change in the interpretation or
         application thereof, or, if no such period is stated therein,
         forthwith.

7.2      If any of the provisions of this Agreement become invalid, illegal or
         unenforceable in any respect under any applicable law, the validity,
         legality and enforceability of the remaining provisions shall not in
         any way be affected or impaired.

8.       ASSIGNMENT AND TRANSFER

         Neither party may assign or transfer (including, without limitation, by
         way of novation) all or any of its rights or obligations under this
         Agreement to any person without the prior written consent of the other
         party, except for the assignment by way of security by the Lender of
         its rights under this Agreement pursuant to the [Debenture].

9.       MISCELLANEOUS

9.1      No failure to exercise and no delay in exercising, on the part of
         either party, any right, power or privilege under this Agreement or any
         other documents ancillary hereto shall operate as a waiver thereof, nor
         shall single or partial exercise of any right, power or privilege
         preclude any other or further exercise thereof, or the exercise of any
         other right, power or privilege. No waiver by the Lender shall be
         effective unless it is in writing.

9.2      All notices or other communications under or in connection with this
         Agreement shall be given in writing and, unless otherwise stated, may
         be made by letter or facsimile. Any such notice will be deemed to be
         given as follows:

         9.2.1    if by letter, when delivered personally or on actual receipt;

         9.2.2    if by facsimile, when received in legible form.

         However, a notice given in accordance with the above but received on a
         non-working day or after business hours in the place of receipt will
         only be deemed to be given on the next working day in that place.

9.3      The address and facsimile number of each party for all notices under or
         in connection with this Agreement are:

         9.3.1    that notified by that party for this purpose to the other
                  party on or before it becomes a party; or

         9.3.2    any other notified by that party for this purpose to the other
                  party by not less than 5 Business Days' notice.

9.4      This Agreement may be executed in any number of counterparts and by the
         parties to it on separate counterparts, each of which shall be an
         original but all of which together shall constitute one and the same
         instrument.

                                      122


9.5      Any amendment or variation of this Agreement shall be in writing and
         signed by each of the parties hereto.

9.6      This Agreement shall be governed by, and interpreted in accordance
         with, English law.

9.7      Each of the parties agrees that the courts of England are (subject to
         Clause 9.8 below) to have non-exclusive jurisdiction to settle any
         dispute (including claims for set-off and counterclaims) which may
         arise in connection with the creation, validity, effect, interpretation
         or performance of, or the legal relationships established by, this
         Agreement or otherwise arising in connection with this Agreement and
         for such purposes irrevocably submits to the jurisdiction of the
         English courts.

9.8      The agreement contained in Clause 9.7 above is included for the benefit
         of the Lender. Accordingly, notwithstanding the exclusive agreement in
         Clause 9.7 above the Lender shall retain the right to bring proceeding
         in any other court which may have jurisdiction, and the Borrower
         irrevocably submits to the jurisdiction of any such court in which the
         Lender shall bring such proceedings.

IN WITNESS WHEREOF this Agreement has been executed by the parties hereto on the
date first stated above.

                         BUSINESS OPPORTUNITY AGREEMENT


         THIS BUSINESS OPPORTUNITY AGREEMENT (this "AGREEMENT"), dated as of
May 1, 1999, is by and among Enron Corp., an Oregon corporation ("ENRON"),
Atlantic Water Trust, a Delaware statutory business trust ("ATLANTIC WATER
TRUST"), and Azurix Corp., a Delaware corporation ("AZURIX"). Atlantic Water
Trust and Azurix are referred to herein collectively as the "AZURIX PARTIES."
Unless the context otherwise requires, references herein to Enron shall be
deemed to be references to Enron and its Affiliates other than Atlantic Water
Trust, Azurix, and entities controlled by either of them.

                              W I T N E S S E T H:

         WHEREAS, Azurix is a wholly owned Subsidiary of Atlantic Water Trust;
and

         WHEREAS, Enron owns a significant beneficial interest in Atlantic Water
Trust; and Enron may owe certain duties to Atlantic Water Trust and Azurix
resulting from its ownership interest in Atlantic Water Trust; and

         WHEREAS, Azurix and Enron are engaged in the Water Business; and

         WHEREAS, Enron engages in, or may engage in the future in, activities
that may have an impact on Atlantic Water Trust and Azurix and their respective
businesses, including the Water Business; and

         WHEREAS, the application of the law relating to duties that Enron may
owe to Atlantic Water Trust and Azurix is often difficult to predict; and if a
court were to hold that Enron breached any such duty, Enron could be held liable
for damages in a legal action brought on behalf of Atlantic Water Trust or
Azurix; and

         WHEREAS, Enron, Atlantic Water Trust, and Azurix desire to enter into
this Agreement in order to (i) define duties that Enron will owe to Atlantic
Water Trust and Azurix with respect to business opportunities; (ii) define
rights that Enron will have with respect to business opportunities; and (iii)
specify certain circumstances which will not give rise to a breach of duty on
the part of Enron; and

         WHEREAS, the Azurix Parties anticipate that they and their Affiliates
will benefit from their relationships with Enron, and Enron's investment in
Atlantic Water Trust was predicated on the execution and delivery of an
agreement containing substantially the terms set forth herein;

         NOW, THEREFORE, in consideration of the mutual covenants, rights, and
obligations set forth in this Agreement and the benefits to be derived herefrom,
and for other good and valuable 







<PAGE>   2


consideration, the receipt and the sufficiency of which each of the parties
hereto acknowledges and confesses, the parties hereto agree as follows:

         SECTION 1. CERTAIN DEFINED TERMS; EXHIBITS. As used in this Agreement,
capitalized terms have the meanings ascribed to such terms in this Agreement and
on Exhibit A attached hereto. Any and all references to "EXHIBITS" are to
Exhibits to this Agreement, each of which is made a part of this Agreement and
incorporated herein for all purposes.

         SECTION 2. REPRESENTATIONS. Each of the parties hereto represents and
warrants to the other parties that it has the power and authority (corporate or
other) to enter into this Agreement and to perform its obligations hereunder and
that the execution, delivery and performance of this Agreement will not conflict
with or result in a violation of any law or any other agreement to which it is a
party or by which it is bound.

         SECTION 3. AGREEMENT BY AZURIX REGARDING ENRON BUSINESS ACTIVITIES.
Azurix acknowledges and agrees that, so long as such activities are conducted in
compliance with this Agreement in all material respects, Enron is free to
conduct business activities that are within Enron's existing lines of business,
including, but not limited to, the Water Business, and any other lines of
business in which Enron chooses to engage in the future. Without limiting the
foregoing, Azurix acknowledges and agrees that, so long as such activities are
conducted in compliance with this Agreement in all material respects, Enron may
engage in any and all aspects of the Water Business. In connection with the
foregoing, Azurix acknowledges that such activities may result in the
acquisition by Enron of Water Business Assets, and in certain cases Enron or
entities in which Enron has an interest may engage in the Water Business or
acquire Water Business Assets pursuant to bidding or auction processes in which
Azurix is also a bidder. Azurix acknowledges and agrees that such activities may
have an impact on Azurix or the price it pays for properties or securities it
purchases from others. Azurix acknowledges and agrees that Enron or entities in
which it has an interest may engage in the Water Business or acquire direct or
indirect interests in Water Business Assets as a result of the activities
described above, may own, operate, and control any such assets in connection
therewith, and may acquire additional Water Business Assets or pursue
opportunities related thereto or in connection therewith, in each case without
any duty to offer all or any portion of such assets or opportunities to Azurix.

         SECTION 4. AGREEMENT BY ENRON REGARDING SEPARATE CONDUCT OF BUSINESS.
Enron agrees that, except with respect to business opportunities pursued jointly
by Enron and Azurix and except as otherwise agreed to between Enron and Azurix,
Enron's business will be conducted through the use of its own personnel and
assets and not with the use of any personnel or assets of Azurix; provided that
nothing herein shall be deemed to prevent Enron from using personnel and
information of Azurix in connection with Enron's decisions regarding its
investment in Atlantic Water Trust, Azurix, or their Affiliates. Without
limiting the foregoing, Enron agrees that, without the consent of Azurix, the
Water Business conducted by Enron entities will only involve business
opportunities identified by or presented to Enron personnel and developed and
pursued solely through the use of the personnel and assets of Enron entities.
Enron agrees that it will not pursue any business opportunity that involves
Water Business Assets that is first presented to an officer or director of Enron
who is also an officer or director of Azurix at the time such opportunity is



                                       2

<PAGE>   3


presented (i.e. the first officer or director of Enron to receive notice of such
opportunity from a third party is also an officer or director of Azurix), or
that such officer or director identified on his or her own, unless Enron first
offers such opportunity to Azurix and within a reasonable period of time Azurix
notifies Enron in writing that Azurix elects not to pursue such opportunity. For
purposes of the foregoing, (a) a business opportunity that involves Water
Business Assets shall not include any opportunity where Water Business Assets
represent less than a majority of the fair market value of the opportunity, as
determined by the officer or director of Enron to whom such opportunity is first
presented, based on information available to such officer or director at the
time such opportunity is first presented (which determination shall be
conclusive if made in good faith), (b) senior officers of Azurix who are members
or ad hoc members of the Management Committee of Enron or any similar committee
shall not, by virtue of such membership or ad hoc membership, be deemed to be
Enron personnel, and (c) it will not be a breach of Enron's agreement to develop
and pursue business opportunities solely through the use of the personnel and
assets of ECT, EES, EII, or other Enron entities if one or more senior officers
of Enron who serve on the Board of Directors of Azurix participate, as officers
of Enron, in evaluating, developing or approving business opportunities that
were identified by other Enron personnel or first presented to other Enron
personnel (i.e. the first Enron person to receive notice of such opportunity
from a third party or who identified the opportunity on his or her own was not
also an officer or director of Azurix). The provisions of this Section 4 relate
exclusively to the duties that Enron owes Azurix, and nothing herein shall
affect the fiduciary or other duties owed to Azurix by any individual director
or officer of Azurix in his or her capacity as such. In this connection, Enron
agrees that its representatives on the Board of Directors of Azurix will not,
for the purpose of enabling Enron to pursue an opportunity in the Water
Business, vote in such a manner as to effectively prevent, prohibit, or restrict
Azurix from pursuing such opportunity.

         SECTION 5. AGREEMENT, WAIVER, RELEASE AND INDEMNITY. In further
consideration of the benefits received and to be received by Azurix pursuant to
this Agreement, Azurix acknowledges and agrees that, if any business opportunity
is presented to or identified by Enron, except as otherwise provided in Section
4 of this Agreement, Enron may pursue such opportunity and conduct the business
related thereto without any obligation to offer it to Azurix. Azurix
acknowledges and agrees that in such case, to the extent that a court might hold
that the pursuit of such opportunity or the conduct of such activity is a breach
of any standard of care, any duty of loyalty, or any other duty to Azurix (and
without admitting that the pursuit of such opportunity or the conduct of such
activity is such a breach of any such standard or duty), Azurix hereby fully and
irrevocably releases and waives any and all Claims that Azurix or any Person
claiming by, through, or under Azurix may have to claim that the pursuit by
Enron of any such business opportunity or the conduct of the business related
thereto is a breach of any standard of care, any duty of loyalty, or any other
duty to Azurix (and including, without limitation, any and all Claims arising
either directly or derivatively, and whether brought by, through, or under
Azurix, or by any stockholder, creditor, or Subsidiary of Azurix). Further,
Azurix, for itself and its successors and assigns, hereby agrees to indemnify,
defend, and hold harmless Enron and its predecessors and successors in interest,
and all of Enron's and its respective predecessors and successors in interests'
respective Affiliates, stockholders, directors, officers, employees, agents,
attorneys, servants, invitees, contractors, licensees, legal representatives,
successors, and assigns, from any and all such Claims that may be asserted (a)
by any Person whomsoever claiming by, through, or under Azurix or (b) by any
successors or assigns of Azurix. It 




                                       3


<PAGE>   4


is the express intention of Azurix that the indemnity to Enron herein provided
covers any such Claims asserted by, through, or under Azurix, notwithstanding
that such Persons are not signatories to this Agreement, and whether or not the
release provisions are directly enforceable against any Persons who are not
signatories to this Agreement. This indemnity applies for the benefit of Enron
(including its predecessors and successors in interest, and all of Enron's and
its respective predecessors and successors in interests' respective Affiliates,
stockholders, directors, officers, employees, agents, attorneys, servants,
invitees, contractors, licensees, legal representatives, successors, and
assigns) regardless of whether such claims are based in whole or in part upon
the alleged partial or sole negligence or strict liability of Enron (or its
predecessors or successors in interest, or Enron's or its respective
predecessors or successors in interests' respective Affiliates, stockholders,
directors, officers, employees, agents, attorneys, servants, invitees,
contractors, licensees, legal representatives, successors, and assigns). The
waivers and agreements herein apply equally to activities to be conducted in the
future and activities that have been conducted in the past.

         SECTION 6. AGREEMENT TO SUPPLY INFORMATION. Enron agrees that, in
connection with any opportunity presented to Azurix pursuant to Section 4 of
this Agreement, Enron will furnish to Azurix all information in Enron's
possession or reasonably available to Enron regarding the opportunity in
question that is material to a decision by Azurix whether or not to pursue such
opportunity; provided, however, that as a condition to the furnishing of such
information, Enron may require Azurix to enter into a written confidentiality
agreement to protect any non-public, confidential, or proprietary information of
Enron or any third party.

         SECTION 7. CONFIDENTIALITY AGREEMENTS, ETC. In the event any party
hereto, or any controlled Affiliate of that party, executes a confidentiality
agreement, an area of mutual interest agreement, a standstill agreement or any
other agreement which purports to bind another party hereto (or any Subsidiary
of such other party), and such other party (or any such Subsidiary of such other
party) is not a party to such agreement, (a) such agreement shall not be binding
on the other party or any of its Subsidiaries (each party acknowledging that
neither it nor any of its Controlled Subsidiaries has any authority to bind any
other party or any other party's Subsidiaries), (b) the other party and its
Subsidiaries shall have no liability for any breach of such agreement, and (c)
the party that executed, or whose controlled Affiliate executed, such agreement
will indemnify, defend, and hold harmless the other party and its Subsidiaries
against any claims arising from or relating to such agreement or any alleged
breach thereof. In the event any third party requires Azurix or Enron to execute
a confidentiality or standstill agreement in order that Enron can furnish to
Azurix, or Azurix can furnish to Enron, any information required by this
Agreement in order to permit Azurix or Enron to exercise any right granted by
this Agreement, Enron and Azurix's obligation in this Agreement to furnish such
information will be conditioned upon the execution of such agreement by Azurix
or Enron, as the case may be.

         SECTION 8.  ARBITRATION.

                  (a) Agreement to Arbitrate. Any and all Claims arising out of
or relating to any provision of this Agreement or the alleged breach hereof,
even though some or all of such Claims allegedly are extracontractual in nature,
whether such Claims sound in contract, tort, or otherwise, at law or in equity,
under domestic, or foreign law, whether provided by statute or the common law,
for damages or any other relief, shall be resolved and decided exclusively by
binding arbitration pursuant to the Federal Arbitration Act in accordance with
the Commercial Arbitration Rules then in effect with the American Arbitration
Association.

                  (b) Procedural Matters. The arbitration proceeding shall be
conducted in Houston, Texas. The arbitration shall be before a panel of three
arbitrators. Each party to such dispute (with the Azurix Parties being
considered one party of any dispute) shall select one arbitrator, and the two
arbitrators selected by the parties shall select the third arbitrator. The
arbitrators are authorized to issue subpoenas for depositions and other
discovery mechanisms, as well as trial subpoenas, in accordance with the Federal
Rules of Civil Procedure. Any party may initiate a proceeding in the appropriate
United States District Court to enforce this provision. This agreement to
arbitrate shall be enforceable in any and all courts (federal, state, or
otherwise). Judgment upon any award rendered in any such arbitration proceeding
may be entered by any court having jurisdiction. The enforcement of this
agreement to arbitrate and all procedural aspects of this agreement to
arbitrate, including the construction and interpretation of this agreement to
arbitrate, the scope of the arbitrable issues, allegations of waiver, delay, or
defenses to arbitrability and the rules governing the conduct of the
arbitration, shall be governed by and construed pursuant to the Federal
Arbitration Act.

                  (c) Amounts Awarded. The arbitrators may award such damages as
they deem appropriate, except that the arbitrators shall have no authority to
award punitive (including, without limitation, any exemplary damages, treble
damages, or any other penalty or punitive type of damages), consequential,
incidental, or indirect damages (in tort, contract, or otherwise), the parties
hereby waiving their right, if any, to recover such damages; provided, however,
that the arbitrators shall have the authority to award damages (including,
without limitation, any punitive damages, exemplary damages, treble damages, or
any other penalty or punitive type of damages or indirect damages, in tort,
contract, or otherwise) that were incurred by a party as a result of a third
party Claim against such party.

                  (d) Costs. The arbitrators shall be entitled to award costs of
the arbitration and attorneys' fees as they deem appropriate.

                  (e) Prior Notice. Prior to the institution of a Claim under
this Agreement by any Person, such Person shall provide to Enron and all other
parties to this Agreement a written notice specifying the nature and basis of
the Claim. The Persons who are the subject of any Claim shall be given thirty
(30) days to cure any breach before any arbitration proceeding is initiated.

                                       5

         SECTION 9.  RESOLUTION OF CONFLICTS OF INTEREST

         (a) Whenever a potential conflict of interest exists or arises between
Enron, on the one hand, and any of the Azurix Parties, on the other hand, any
resolution or course of action in respect of such conflict of interest shall be
permitted and deemed approved by all parties, and shall not constitute a breach
of any duty stated or implied by law or equity, if the resolution or course of
action is authorized by this Agreement or, by operation of this Agreement, is
deemed to be fair and reasonable to the Azurix Parties. Enron shall be
authorized but not required in connection with its resolution of such conflict
of interest to seek Special Approval of a resolution of such conflict or course
of action. The term "SPECIAL APPROVAL" shall mean the approval of a majority of
disinterested directors of Azurix. Any conflict of interest and any resolution
of such conflict of interest shall be conclusively deemed fair and reasonable to
the Azurix Parties if such conflict of interest or resolution is (i) approved by
Special Approval, or (ii) on terms no less favorable to the Azurix Parties than
those generally being provided to or available from unrelated third parties, or
(iii) fair to the Azurix Parties, taking into account the totality of the
relationships between the parties involved (including other transactions that
may be particularly favorable or advantageous to one or more of the Azurix
Parties). Enron may also adopt a resolution or course of action that has not
received Special Approval. Enron and any Person voting in connection with
Special Approval shall be authorized in connection with its determination of
what is "fair and reasonable" to the Azurix Parties and in connection with its
resolution of any conflict of interest to consider (A) the relative interests of
any party to such conflict, agreement, transaction, or situation and the
benefits and burdens relating to such interest; (B) any customary or accepted
industry practices and any customary or historical dealings with a particular
Person; (C) any applicable generally accepted accounting or engineering
practices or principles; and (D) such additional factors as such Person
determines in its sole discretion to be relevant, reasonable, or appropriate
under the circumstances. In the absence of bad faith by Enron, the resolution,
action, or terms so made, taken, or provided by Enron with respect to such
matter shall not constitute a breach of this Agreement or any other agreement
contemplated herein or a breach of any standard of care, any duty of loyalty, or
any other duty imposed herein or therein or under Delaware law or any other law,
rule, or regulation.

         (b) Any standard of care, any duty of loyalty, and any other duty
imposed by this Agreement or under Delaware law or any other applicable law,
rule, or regulation shall be modified, waived, or limited as required to permit
Enron to act under this Agreement and to make any decision pursuant to the
authority prescribed in this Agreement so long as such action is reasonably
believed by Enron to be in, or not inconsistent with, this Agreement or the
interests of the Azurix Parties.

         SECTION 10. AMENDMENT OF AZURIX'S PURPOSE CLAUSE. Azurix, Atlantic
Water Trust, and Enron agree that, as soon as practicable following the
execution and delivery of this Agreement, they will take such action as is
necessary to cause the purpose clause of Azurix in its Certificate of
Incorporation to be amended to read as follows:

                  The purpose of the Corporation is to engage, directly or
                  indirectly (through affiliates or otherwise), in acquiring,
                  owning, operating, and managing water and wastewater assets,
                  providing water- and wastewater- related services, and
                  developing and managing water resources, including without

                  rights and other interests in real property held primarily for
                  use in production, collection, or storage of water), (iii) the
                  ownership and operation of real and personal property used or

                  from wells located on water properties, and storage and

                  systems, and rights of way, licenses and other rights
                  associated therewith, (iv) the ownership and operation of real
                  and personal property used or useful in connection with water
                  and wastewater collection, treatment, distribution, and
                  disposal operations, including, but not limited to,
                  reservoirs, wells, abstraction devices, pipelines, aqueducts,
                  desalination plants, water treatment facilities, distribution
                  networks, wastewater collection networks, and wastewater
                  treatment facilities, (v) service agreements that relate to
                  the management of water supply or water or wastewater
                  facilities or systems, including, but not limited to, water
                  and wastewater system management contracts and "back office"
                  services agreements, (vi) the operation, management, and
                  provision of architectural, engineering, and construction
                  services related to the foregoing, (vii) services and assets
                  to dispose of residual products from wastewater treatment,
                  (viii) remediation and development of underground
                  infrastructure related to water and wastewater systems and
                  supply, (ix) risk management services involving water
                  supplies, (x) debt of or equity interests in corporations,
                  partnerships, or other entities engaged in businesses that the
                  Corporation is permitted hereby to engage in, (xi) any other
                  lawful business or activity that now or hereafter may be
                  incidental to the foregoing purpose or acquired as part of a
                  larger acquisition transaction the majority of the value of
                  which (as determined by the Board of Directors of the
                  Corporation or its designee in good faith) relates to one or
                  more of the foregoing purposes, but excluding (in the case of
                  each of items (i) through (xi)) supplying fuel, supplying
                  energy (other than sales of excess generation from facilities
                  principally serving assets or facilities described in items
                  (i), (iii), (iv) and (vii) above), or providing risk
                  management services on a commodity other than water (other
                  than being a party to a risk management arrangement to protect
                  against risks facing the Corporation), and (xii) any other
                  lawful business or activity; provided that such other business
                  or activity contemplated by this clause (xii) is approved in
                  writing by Enron Corp., an Oregon corporation, which approval
                  may be granted or withheld by Enron Corp. in its sole
                  discretion and which approval may be general in nature or may
                  be confined to a particular facility or a particularly
                  described expanded business purpose. Notwithstanding the
                  foregoing, from and after the first date on which both of the
                  following tests are met: (a) Enron Corp. and affiliates of
                  Enron Corp. do not individually or collectively, directly or
                  indirectly, own or have the power to vote at least one-third
                  of the capital stock of the Corporation having ordinary voting
                  power for the election of 




                                       7

<PAGE>   8


                  directors, and (b) fewer than one-third of the directors of
                  the Corporation are persons who are employees, officers or
                  directors of Enron Corp. or of any affiliate of Enron Corp.,
                  the purpose of the Corporation shall be to engage in any
                  lawful business or activity in which a corporation organized
                  under the laws of Delaware is permitted to engage under
                  Delaware law.

Azurix agrees that, until the first date on which both of the following tests
are met: (a) Enron and Affiliates of Enron do not individually or collectively,
directly or indirectly, own or have the power to vote at least one-third of the
capital stock of Azurix having ordinary voting power for the election of
directors, and (b) fewer than one-third of the directors of Azurix are persons
who are employees, officers or directors of Enron or of any Affiliate of Enron,
without the prior written consent of Enron (which consent Enron may grant or
withhold in its sole discretion), Azurix will not further amend the purpose
clause of its Certificate of Incorporation. Azurix also agrees that, to the
extent practicable, it will take such action as it deems appropriate to ensure
that its activities and the activities conducted by its Controlled Subsidiaries
are conducted in a manner that is consistent with the foregoing purpose clause.

         SECTION 11. DUTIES OF INDIVIDUAL DIRECTORS. Nothing herein shall affect
the fiduciary or other duties owed to Atlantic Water Trust or Azurix by any
individual director or officer of Atlantic Water Trust or Azurix in his or her
capacity as such.

         SECTION 12. DUTIES TO EXISTING ENTITIES. The Azurix Parties acknowledge
that Enron has fiduciary and contractual obligations to other Persons and
entities under existing agreements and relationships and agree that, in the
event of a conflict between the duties of Enron under this Agreement and the
duties of Enron to third parties under agreements or relationships that exist on
the date hereof, Enron shall be entitled to perform its duties to such third
parties without any liability to the Azurix Parties. Without limitation or
exclusion to any other agreements or relationships that Enron has in or
affecting the Water Business on the date hereof, the parties acknowledge that
Enron has furnished to Azurix a confidential list of transactions or
relationships that Enron currently has in or affecting the Water Business or
Water Business Assets and for which Azurix fully and irrevocably waives and
releases any and all Claims with respect thereto.

         SECTION 13. MISCELLANEOUS PROVISIONS.

                  (a) Governing Law and Venue. This Agreement shall be governed
by and construed and enforced in accordance with the laws of Delaware without
regard to principles of conflicts of law.

                  (b) Third Party Beneficiaries. The terms and conditions of
this Agreement shall inure to the benefit of and be binding upon the parties
hereto and their successors and permitted assigns. This Agreement is also
intended for the benefit of each member of the Board of Directors of Enron,
Atlantic Water Trust and Azurix, each of which will be considered a third party
beneficiary of this Agreement.

that the other party may also employ such Person, and each party waives the
right to claim that the other party breached any duty to it in connection with

                               SERVICES AGREEMENT

         This Services Agreement (this "Agreement") is made and entered into as
of May 1, 1999, between Enron Corp., an Oregon corporation ("Enron"), and
Azurix Corp., a Delaware corporation ("Azurix"). Azurix and Enron may
hereinafter be referred to individually as a "Party" or collectively as the
"Parties."

                                   RECITALS:

         WHEREAS, Enron and Azurix desire by their execution of this Agreement
to evidence their understanding concerning the provision of certain services by
Enron to Azurix and its subsidiaries;

         NOW, THEREFORE, for and in consideration of the mutual promises and
conditions contained herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Parties hereto
hereby agree as follows:

         1. Services. In order to assist the continued and orderly conduct of
certain corporate functions currently performed by Enron and its affiliates for
the benefit of the Referenced Subsidiaries (defined below), Enron agrees to
provide and Azurix agrees to purchase, subject to the terms and conditions set
forth herein, certain corporate staff and support services, as identified in
Exhibit A attached hereto (collectively, the "Services"), in each case if and
only to the extent requested by Azurix. "Referenced Subsidiaries" shall mean
Azurix and its subsidiaries from time to time. Such subsidiaries shall
initially include, without limitation, those subsidiaries listed on Exhibit B.

         2. Term. This Agreement shall become effective and Enron shall make
the Services available to the Referenced Subsidiaries pursuant to the terms of
this Agreement for the period commencing on May 1, 1999, and terminating on
the date 180 days following written notice by either party to the other (or
earlier by mutual written agreement); provided, however, (i) the Referenced
Subsidiaries shall remain responsible for all out-of-pocket costs and expenses
incurred by Enron pursuant to agreements entered into by Enron for the benefit
of the Referenced Subsidiaries that could not be terminated prior to the date
of termination of this Agreement, and (ii) upon the mutual agreement of Azurix
and Enron, services may be provided beyond the termination date set forth in
the notice in order to allow the Referenced Subsidiaries the opportunity to
make alternative arrangements for such services. In



<PAGE>   2

the event any of the Services being performed hereunder are no longer
available, Enron, any Enron subsidiary or affiliate, then Enron shall be
relieved of its obligations under this Agreement to provide that particular
Service to the Referenced Subsidiaries. The foregoing shall include any
cessation of or failure of Services due to Year 2000 problems. Enron will
advise the Referenced Subsidiaries of any cessation of Services and shall use
commercially reasonable judgement in assisting the Referenced Subsidiaries in
securing alternative services for the Referenced Subsidiaries.

         3. Nature and Quality of Services. The Parties understand and agree
that the Services shall be substantially identical in nature and quality to the
Services provided by Enron to its wholly-owned subsidiaries.

         4. Payment. Azurix, as compensation for the performance of the
Services, agrees to reimburse Enron for: (i) all expenses actually incurred by
Enron and readily identifiable to the Referenced Subsidiaries relating to the
Services ("Direct Charges"), which calculation shall be based on the cost of
such Services to Enron and charged to the Referenced Subsidiaries in the same
manner as costs charged to other Enron subsidiaries or affiliated companies and
in accordance with the charge bases identified on Exhibit A, if applicable;
(ii) the actual cost of any goods or services purchased specifically for the
Referenced Subsidiaries by Enron from third parties unaffiliated with Enron
("Operating Charges"); (iii) the actual cost or charge for outsourced services
provided by any third party unaffiliated with Enron specifically for the
Referenced Subsidiaries under an Enron or Enron affiliate agreement with such
third party ("Outsourced Charges"); and (iv) an overhead allocation to the
Referenced Subsidiaries of administrative and general expenses of Enron
corporate staff and support services reasonably related to the amount of such
services provided to the Referenced Subsidiaries for which Azurix does not
receive Direct Charges ("Allocated Charge"). Such Allocated Charge shall be
payable in monthly installments.

         If the compensation for the Services does not include sales, use,
excise, value-added or similar taxes, and if any such taxes are imposed on the
Services after the effective date of this Agreement, then such taxes shall be
promptly paid by Azurix.

         Any change in the methodology due to regulatory, accounting or legal
reasons, to be used for determining any Direct Charges, Operating Charges,
Outsourced Charges, Allocated Charges or any other charge for Services provided
by Enron, any Enron affiliate or third party, for the Referenced Subsidiaries


                                       2
<PAGE>   3

from that being used on the effective date of this Agreement shall be deemed
agreed to by Azurix without the necessity of getting Azurix's consent so long
as such changes are in good faith and are charged or allocated to the
Referenced Subsidiaries in the same manner as to the other Enron subsidiaries
or affiliated companies. 

         5. Invoicing. Enron shall invoice Azurix by the 15th working day of
each month for all Direct Charges, Operating Charges, Outsourced Charges and
Allocated Charges, all with respect to the preceding month. All invoices shall
reflect in reasonable detail a description of the Services performed during the
preceding month, and shall be due and payable on the last day of the month of
the invoice. In the event of a dispute as to the propriety of invoiced amounts,
Azurix shall pay all undisputed amounts on each invoice, but shall be entitled
to withhold payment of any amount in dispute and shall promptly notify Enron of
such dispute. Enron or its applicable affiliate shall provide Azurix with
records relating to the disputed amount so as to enable the Parties to resolve
the dispute. Azurix shall pay interest at an annual rate of 18% on any disputed
amounts which it should have paid but withheld.

         6. Confidentiality. Each party shall exert the same efforts and
maintain the same precautions that it exerts and maintains with respect to its
own confidential and proprietary information with respect to all information
received from the other party in connection with the performance of the
Services; provided, however, that a party may disclose such information (i) if
required to do so by applicable laws, rules, regulations, or orders (including
any laws, rules, regulations or orders to which either party voluntarily
subjects itself and any applicable securities exchange rules), or (ii) if such
information was or becomes generally available to such party on a
non-confidential basis, provided that the source of such information was not
known by such party to be bound by a confidentiality obligation.

         7. Information from Azurix. Any information necessary for Enron or any
third party to perform any Services shall be submitted by Azurix in a manner
consistent with the practices utilized by the Referenced Subsidiaries during
the period immediately prior to the effective date of this Agreement, which
manner shall not be altered except by mutual written agreement of the Parties.
Should Azurix's failure to supply such input render Enron's or any third
party's performance of any Services unreasonably difficult, Enron or such third
party, upon reasonable notice to Azurix, may refuse to perform such Services
until such input is supplied.

                                       3
<PAGE>   4

         8. Sole Beneficiaries. Azurix acknowledges that the Services shall be
provided only with respect to the business of Azurix and its subsidiaries or
affiliates. Azurix will not request performance of any Services for the benefit
of any entity other than Azurix and its subsidiaries or affiliates. Azurix
represents and agrees that it will use the Services only in accordance with all
applicable federal, state and local laws and regulations and communications and
common carrier tariffs, and in accordance with the reasonable conditions,
rules, regulations and specifications which may be set forth in any manuals,
materials, documents or instructions in existence on the effective date of this
Agreement and furnished by Enron to Azurix. Enron reserves the right to take
all actions, including termination of any particular Services, that Enron
reasonably believes to be necessary to assure compliance with applicable laws,
regulations and tariffs.

         9. User Codes and Passwords. Enron will assign to the Referenced
Subsidiaries all user codes, passwords or numbers, or other control or
identifying cards or numbers, necessary for Enron to perform the Services.
Azurix assumes full responsibility for selection and use of any such codes,
passwords, cards or numbers that may be permitted or required in connection
with the Services involved.

         10. LIMITED WARRANTY; LIMITATION OF LIABILITY. ALL PRODUCTS OBTAINED
FOR THE REFERENCED SUBSIDIARIES ARE AS IS, WHERE IS, AS TO ENRON, WITH ALL
FAULTS, OTHER THAN FAULTS DUE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
ENRON. NEITHER ENRON NOR ANY ENRON AFFILIATE PERFORMING ANY SERVICES HEREUNDER
MAKE ANY WARRANTIES OR REPRESENTATIONS WHATSOEVER, EXPRESS OR IMPLIED,
INCLUDING THE WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE
WITH RESPECT TO THE SERVICES RENDERED FOR OR PRODUCTS OBTAINED FOR THE
REFERENCED SUBSIDIARIES, INCLUDING WITHOUT LIMITATION THOSE RENDERED BY OR
OBTAINED FROM A THIRD PARTY. NOTWITHSTANDING THE FOREGOING, TO THE EXTENT A
WARRANTY PROVIDED BY A THIRD PARTY MANUFACTURER OR PROVIDER OF GOODS OR
SERVICES TO ENRON OR ITS AFFILIATES CAN BE PASSED-ON TO THE REFERENCED
SUBSIDIARIES, NOTHING HEREIN IS INTENDED TO LIMIT SAME AND THE REFERENCED
SUBSIDIARIES SHALL HAVE THE RIGHT TO THE


                                       4
<PAGE>   5

BENEFITS (SUBJECT TO THE TERMS AND CONDITIONS THEREOF) OF ALL SUCH THIRD PARTY
WARRANTIES.

         IN NO EVENT SHALL EITHER ENRON OR THE REFERENCED SUBSIDIARIES BE
LIABLE TO THE OTHER PARTY OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL OR
CONSEQUENTIAL DAMAGES RESULTING FROM ANY ERROR IN THE PERFORMANCE OF SERVICES
OR FROM THE BREACH OF THIS AGREEMENT, REGARDLESS OF FAULT. TO THE EXTENT ANY
THIRD PARTY HAS LIMITED ITS LIABILITY TO ENRON FOR SERVICES UNDER AN
OUTSOURCING OR OTHER AGREEMENT, THE REFERENCED SUBSIDIARIES AGREE TO BE BOUND
BY SUCH LIMITATION OF LIABILITY FOR ANY PRODUCT OR SERVICE PROVIDED TO ENRON BY
SUCH THIRD PARTY UNDER SUCH AGREEMENT.

         11. Force Majeure. Enron shall have no obligation to perform the
Services if its failure to do so is caused by or results from any act of God,
governmental action, natural disaster, strike, failure of essential equipment,
Y2K problem, or any other cause or circumstance beyond the control of Enron.
Enron agrees that upon restoring service following any failure of any equipment
necessary for Enron or its affiliates to provide any Services, Enron will allow
the Referenced Subsidiaries to have equal priority, in accordance with prior
practice, with respect to access to the restored service.

         12. Severability. In the event any portion of this Agreement shall be
found by a court of competent jurisdiction to be unenforceable, that portion of
the Agreement will be null and void and the remainder of the Agreement will be
binding on the Parties as if the unenforceable provisions had never been
contained herein.

         13. Assignment. This Agreement shall not be assignable by either of
the Parties hereto except by operation of law or with the written consent of
the non-assigning Party.

         14. Entire Agreement; Amendment. This Agreement constitutes the entire
agreement of the Parties relating to the performance of the Services and all
prior or contemporaneous written or oral agreements are merged herein. This
Agreement may not be amended or otherwise modified except by a writing signed
by both Parties.

         15. Choice of Law. This Agreement shall be governed by the laws of the
State of Texas,

                                       5
<PAGE>   6

without regard to any conflict-of-law rule or principle that might refer the
construction or interpretation of this Agreement to the laws of another state.

         16. Notice. Any notice, request, instruction, correspondence or other
document to be given hereunder by either Party to the other (herein
collectively called "Notice") shall be in writing and delivered personally or

                        NON-EXCLUSIVE LICENSE AGREEMENT


         This Non-Exclusive License Agreement ("Agreement") is entered into as
of May 1, 1999, by and between Enron Corp., a corporation organization and

         WHEREAS, Licensor is the owner of the name and Mark "Enron" and its
Fanciful E Logo, as well as goodwill and business interest associated with such
name and Mark; and

         WHEREAS, Licensee is desirous of using the Enron name and the Fanciful
E Logo in association with the name of Licensee in accordance with the terms
and conditions of this Agreement.

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained herein, the receipt and sufficiency of which are hereby acknowledged,
Licensor and Licensee agree as follows:

         1.      Except as otherwise provided herein, Licensor hereby grants to
Licensee, and Licensee accepts, a non- exclusive, non-transferable,
royalty-free and worldwide right and license to use, in connection with
Licensee's name, logo and Web page(s), the Identifying Phrase "an Enron

Logo for purposes of identifying Azurix as part of Enron's enterprise.
Licensee's use of such Identifying Phrase and the aforementioned Marks shall be
pursuant to the terms and conditions of this Agreement.

         2.      Notwithstanding anything to the contrary provided herein,
Licensee agrees that it shall not use the Identifying Phrase or the Fanciful E
Logo, or any terms confusingly similar thereto, in connection with any business
other than the water business as described in Exhibit 1 hereto.

         3.      Licensee shall use the Identifying Phrase only as authorized
herein by Licensor and in accordance with such standards of quality as Licensor
may establish.  Licensor shall at all times remain the owner of the name and
Mark "Enron" and the Fanciful E Logo, and any variation or use of same;

extended automatically and repetitively for similar terms unless otherwise
terminated in accordance with the provisions set forth herein.


         5.      This Agreement and the non-exclusive license granted herein 
shall terminate as follows:

         (a)     This Agreement and the non-exclusive license granted herein
         may be terminated by Licensor at any time for Cause, which is defined
         as a material breach of this Agreement or the use of the Identifying
         Phrase or the Fanciful E Logo in ways or circumstances detrimental to
         Licensor, by the giving of a written notice of breach or detrimental
         use to the defaulting party, and, if such breach or detrimental use is
         not cured within thirty (30) days.  Thereafter this Agreement and the
         non-exclusive license granted herein shall terminate.

         (b)     This Agreement and the non-exclusive license granted herein may
         be terminated by Licensor for any reason if both of the following
         conditions have occurred:

                 (i)      Licensor and affiliates of Licensor do not 
                          individually or collectively, directly or indirectly,
                          own or have the power to vote at least one-third of
                          the capital stock of Licensee having ordinary voting
                          power for the election of directors, and

                 (ii)     Fewer than one-third of the directors of Licensee are
                          persons who are employees, officers or directors of
                          Licensor or of any affiliate of Licensor.

         (c)     This Agreement and the non-exclusive license granted herein may
         be terminated by Licensor or by Licensee as of any date on at least 90
         days written notice.

         6.      Upon termination of this Agreement and the non-exclusive 
license granted herein, Licensee shall immediately cease all use of the
Identifying Phrase and the Fanciful E Logo, and phase out the then-existing
supply of stationery or supplies containing the Identifying Phrase or the

Agreement shall be that of independent contractors.  Licensor shall not by
virtue of this Agreement control or have the right to control the methods and

understanding between the parties with respect to the subject matter hereof and

                           (i) Class A Beneficial Interest (the "Class A
         Interest") representing Marlin's Contributions; and

                           (ii) Class B Beneficial Interest (the "Class B

                  (b) Any Class A Interest purchased by the Beneficial Owner of
         the Class B Interest pursuant to Section 8(h) of the Remarketing

                  (c) The Beneficial Interests shall be evidenced by trust

Beneficial Interest if directed by the majority of the Board of Directors upon
receipt of contributions in respect thereof; provided, that any such additional
class of beneficial interest and the rights of such additional class of
beneficial owners to the Trust's assets shall be subordinate and junior to the
Class A Interest in all respects; provided, further, that the right of the
Beneficial Owner of the Class A Interest to appoint members of the Board of
Directors of the Trust in accordance with Section 6.01 shall in no way be
diluted as a result of the establishment of such additional class of beneficial
interest. In the case of any distributions of amounts on deposit in the

and any distribution of the Trust's assets following a termination of the Trust
in accordance with Section 9.02, any amounts owing to the Beneficial Owners of
the Class A Interest shall be paid in full in cash before any further payment or
distribution is made to such additional class of beneficial owners. In the event
that notwithstanding the provision of this Agreement any beneficial owner of
such additional class shall have received any payment or distribution in respect
of such Beneficial Interest contrary to the provisions of this Agreement, then,
unless and until the Class A Interest and all other amounts payable hereunder to
the Beneficial Owners thereof shall have been paid in full in cash, such payment
or distribution shall be received and held in trust for the benefit of, and
shall forthwith be paid over and delivered to, the Beneficial Owners of the
Class A Interest. Any holder of such additional class of Beneficial Interest
shall not be entitled to demand, accept or receive any payment or distribution
in respect of such Beneficial Interest in violation of the provisions of this
Agreement.

the right, but not the obligation, to contribute Enron Equity Sales Proceeds to
the Trust upon the occurrence of a Marlin Note Trigger Event or on any date not
more than 150 days prior to the Maturity Date if (A) the Holders of the Marlin
Senior Notes, Marlin and the Co-Issuer have not unanimously agreed, with each
having the right not to agree in its sole, unfettered discretion, to reset the
interest rate and maturity on the Marlin Senior Notes, or (B) despite such
unanimous agreement by the Holders of the Marlin Senior Notes, Marlin and the
Co-Issuer, Enron and Marlin have not agreed, with each having the right not to
agree in its sole, unfettered discretion, to corresponding changes to the
distribution provisions set forth in Section 4.03 of this Agreement all within
two Business Days of Enron's request to reset such terms. The Beneficial Owner
of the Class B Interest agrees that any additional contribution made by such
Beneficial Owner after the Closing Date shall be in cash only.

                  such amounts to be retained in the Atlantic Water Asset

                           fourth, to the Beneficial Owner of the Class A

direct the Trustee to apply an amount equal to the Base Amount (the "Deferred
Class A Distribution") in accordance with Section 4.06 and (B) the Beneficial
Owner of the Class B Interest shall have the right to elect not to receive all
or any portion of the distributions it is otherwise entitled to receive in
accordance with Section 4.03 and to direct the Trust as to the application of
such amounts.

                  Section 4.04. Distribution Date Statements. On each
Distribution Date on which funds are being distributed pursuant to Section 4.03
hereof, the Trustee shall prepare and deliver to the Beneficial Owners and the
Indenture Trustee a statement (a "Distribution Date Statement") setting forth
for the period since the preceding Distribution Date (i) the amount, nature and
origin of all income, proceeds, payments and collections received in each
subaccount of the Distribution Account, (ii) the amounts to be paid or
distributed pursuant to Section 4.03 hereof and (iii) the balances of the Trust
Accounts after giving effect to the distributions made on such day.

                  Section 4.05. Trust Accounts. A separate account (a "Trust
Account") shall be established and maintained on the books of the Trustee for
each class of Beneficial Interest:

                  (a) Class A Trust Account. The Trust Account for the Class A
Interest shall be credited with the Initial Class A Contribution on the Closing
Date and throughout the 


                                       14
<PAGE>   18

existence of the Trust shall be (x) increased (i) by the amount of any
additional Contributions made by the Beneficial Owners of the Class A Interest
after the Closing Date and (ii) at any time the Class A Allocated Losses are
greater than zero, by the cash gains, if any, realized by the Trust on any of
the assets in the Trust Estate up to an amount equal to the Class A Allocated
Losses as of the date such gains are realized (such gains, the "Class A
Allocated Gains"), and (y) decreased (i) upon any reduction in the aggregate
outstanding principal amount of the Marlin Senior Notes, by an amount equal to
such reduction, regardless of whether as a result of distributions from the
Trust, (ii) upon any repayment of the Base Amount, by an amount equal to such
payment (it being understood, for the avoidance of doubt, that the Class A Trust
Account shall be unaffected by any Class A Priority Distribution made to the
Beneficial Owner of the Class A Interest, by any payment of Default Interest
Amount or Default Yield, by any payment in respect of the Optional Redemption
Price or any Mandatory Redemption Price in excess of the principal balance of
the Marlin Senior Notes and by any payment in respect of the Marlin Certificate
Price in excess of the Base Amount, and (iii) by the cash losses, if any,
realized by the Trust on any of the assets in the Trust Estate in excess of the
balance of the Class B Trust Account as of the date such losses are realized
(such losses, the "Class A Allocated Losses").

                  (b) Class B Trust Account. The Trust Account for the Class B
Interest shall be credited with the Initial Class B Contribution on the Closing
Date, and throughout the existence of the Trust shall be (a) increased by (i)
the amount of any additional Contributions made by the Beneficial Owners of the
Class B Interest after the Closing Date, (ii) the amount applied to the payment
of the principal of the Marlin Senior Notes in the case payment is made by Enron
to Marlin in accordance with Section 8(h) of the Remarketing Agreement, and
(iii) the cash gains, if any, realized by the Trust on any of the assets in the
Trust Estate in excess of the Class A Allocated Gains and (b) decreased by (i)
the cash losses, if any, realized by the Trust on any of the assets in the Trust
Estate (to the extent of the balance of the Class B Trust Account), and (ii) all
amounts distributed to the Beneficial Owner of the Class B Interest (it being
understood, for avoidance of doubt, that the Class B Trust Account shall be
unaffected by any distribution or deemed distribution to the Beneficial Owner of
the Class B Interest made from Atlantic Water Equity Sales Proceeds resulting
from one or more sales of a portion of Enron's Class B Interest).

                  Section 4.06. Deferred Class A Distribution; Bristol Water
Dividends; Azurix Europe Residual Proceeds and Azurix Europe Residual Proceeds
Account. (a) If the Beneficial Owner of the Class A Interest exercises its right
under Section 4.03(c), the Trust shall contribute, or at the direction of the
Board of Directors (if and to the extent such direction is delivered to the
Trustee within two (2) Business Days of the Base Amount Deferral Date), lend to
Azurix an amount equal to the Deferred Class A Distribution.

                  (b) Any amounts received by the Trust as the owner of the
beneficial interests of Bristol Water Trust (such amounts, "Bristol Water
Dividends"), if and when such amounts are received by the Trust shall be applied
by the Trust as an additional capital contribution to Azurix, or at the
direction of the Board of Directors (if and to the extent such direction is
delivered to the Trustee within two (2) Business Days after such amounts are
received by the Trust), loaned to Azurix.


                                       15
<PAGE>   19

                  (c) The Trustee, in the name, and on behalf, of the Trust,
shall establish and maintain in the name of the Trust an account with Bankers
Trust International (the "Azurix Europe Residual Proceeds Account"), into which
shall be deposited any payments received by the Trust from the Azurix Europe
Interest Account (Sterling) and the Azurix Europe Note Proceeds Account
(Sterling), each established under the Indenture (such payments, the "Azurix
Europe Residual Payments"). Such account shall bear a designation clearly
indicating that the funds deposited therein are held for the benefit of the
Trust. Any amounts on deposit in the Azurix Europe Residual Proceeds Account
shall be applied by the Trust as an additional capital contribution to Azurix,
or at the direction of the Beneficial Owner of the Class B Interest (if and to
the extent such direction is delivered to the Trustee within two (2) Business
Days after such amounts are deposited into the Azurix Europe Residual Proceeds
Account), loaned to Azurix.

                  Section 4.07. Class A Priority Distribution. The Beneficial
Owner of the Class A Interest shall be entitled to receive, on each Payment
Date, so long as the balance of the Class A Trust Account is greater than zero,
a distribution in an amount equal to the sum of (x) any Marlin Interest Amount
then due and payable and (y) Marlin Certificate Yield then due and payable or in
the case of a Base Amount Deferral by the Marlin Certificateholders pursuant to
Sections 5.04 or 6.02 of the Marlin Trust Agreement, the Treasury Yield due and
payable as described in Section 5.06 of the Marlin Trust Agreement (the "Class A
Priority Distribution"). The obligation of the Trust to make such distribution
shall be deemed satisfied to the extent payments are deposited by, or at the
direction of, Bristol Water Trust to the accounts established under the
Indenture in accordance with Section 5.4 of the Participation Agreement.

                  Section 4.08. Certain Limitations on the Rights of Class A
Interest. Notwithstanding anything else herein to the contrary, the Beneficial
Owner of Class A Interest shall be entitled to receive distributions in
accordance with this Article IV, only so long as the then current balance of the
Class A Trust Account is greater than zero. In the event the balance of the
Class A Trust Account is reduced to zero, the rights of the Beneficial Owner of
the Class A Interest hereunder, including, without limitation, its rights under
Article VI, shall be terminated.


                                    ARTICLE V

              LIMITATION ON THE LIABILITY OF THE BENEFICIAL OWNERS

                  Section 5.01. Liability of Beneficial Owners. None of the
Beneficial Owners shall be liable to any third party for any debt, claim,
demand, judgment or obligation of any kind of, against or with respect to the
Trust by reason of its status as a beneficial owner of the Trust, nor shall
either Beneficial Owner, solely by reason of its status as such, be subject to
any personal liability whatsoever, in tort, contract or otherwise, to any third
party in connection with the property, liabilities or affairs of the Trust. For
the avoidance of doubt, the foregoing sentence shall in no way limit the
obligations of the Depositor under Sections 7.07, 7.08 and 7.09.

                                   ARTICLE VI

                      BENEFICIAL OWNERS; BOARD OF DIRECTORS

                  Section 6.01. Management of the Trust. (a) General. It is the
intention of the parties hereto that, the Trustee's duties are to be ministerial
in nature only, except as otherwise expressly provided herein. Subject to
Section 9.01 hereof, the Beneficial Owners, directly or acting through the Board
of Directors, shall have the right and obligation to determine the matters
herein referenced to be determined by the Beneficial Owners and to direct the
Trustee to conduct such matters. Subject to the provisions of the Act, the
Beneficial Owners, directly or acting through the Board of Directors, shall
direct the management of the business and affairs of the Trust in order best to
carry out its purposes. In the event the direction or instruction given to the
Trustee by a Beneficial Owner in accordance with, and as provided by, the terms
hereof conflicts or is inconsistent with the direction or instruction given by
the Board of Directors, the direction or instruction given by such Beneficial
Owner(s) shall govern.

                  (b) Board of Directors. Unless otherwise set forth in this
Agreement, and subject to the provisions of the Transaction Documents, the Board
of Directors shall have the right to vote on all customary trust governance
matters, as would a board of directors for a corporation organized under the
laws of Delaware ; provided that (i) the expenditure by Azurix or Azurix Ltd. or
any of their subsidiaries (other than Azurix Europe's subsidiaries, as to which
no limit shall apply) of up to an aggregate of $2,400,000,000 on acquisitions
and other development activities, (ii) any contributions or loans made to Azurix
pursuant to Section 4.06(c) and (iii) equity offerings by Azurix or Azurix Ltd.
or any of their subsidiaries shall not require any vote or approval by the Board
of Directors, and in each case shall be at the direction of the Beneficial Owner
of the Class B Interest.

                           (i) Number of Board Members: The Board of Directors
                  shall initially consist of an even number of members not
                  greater than ten. The Beneficial Owners of each of the Class A
                  Interest and the Class B Interest shall have the power at all
                  times to appoint up to 50% of the Board of Directors (each
                  director so appointed by the Beneficial Owner of the Class A
                  Interest hereinafter referred to as the "Class A Designated
                  Director" and each director so appointed by the Beneficial
                  Owner of the Class B Interest hereinafter referred to as the
                  "Class B Designated Director"). The Beneficial Owners of each
                  of the Class A Interest and the Class B Interest shall have
                  the right, at any time without cause, to remove any of the
                  directors appointed by them upon prior written notice to the
                  Trustee and the Beneficial Owner of the other Class. If the
                  Beneficial Owner of the Class A Interest has not appointed all
                  the directors that it is entitled to appoint, the Beneficial
                  Owner of the Class B Interest shall have the right to appoint
                  such directors (each, an "Additional Class B Director");
                  provided, however, the Beneficial Owner of the Class A
                  Interest shall have the right, at any time without cause (upon
                  prior written notice), to remove any Additional Class B
                  Director, provided, further, that in no event shall the
                  Beneficial Owner of the Class A Interest have the right to
                  remove, at any time, more directors than such Beneficial 


                                       17
<PAGE>   21

                  Owner is entitled to appoint at such time. The Beneficial
                  Owner of the Class A Interest shall have the right to appoint
                  other members to the Board of Directors in place of any
                  directors removed by such Beneficial Owner.

                           (ii) Quorum. A majority of the members of the Board
                  of Directors at the time of any decision making, one of whom
                  shall be a Class B Designated Director (as to which fact there
                  shall be delivered to the Trustee a duly executed certificate
                  of a member of the Board of Directors), shall be present in
                  making any decision of the Board of Directors, and the
                  affirmative vote of a majority of the directors constituting
                  such quorum shall be necessary for any action or decision made
                  by the Board of Directors.

                           (iii) Delivery of Information to the Beneficial Owner
                  of the Class A Interest. During any period that the Beneficial
                  Owner of the Class A Interest has not appointed any Class A
                  Designated Director, the Beneficial Owner of the Class B
                  Interest shall deliver or cause to be delivered to the
                  Beneficial Owner of the Class A Interest, no later than 10
                  Business Days prior to any proposed meeting of the Board of
                  Directors, an agenda setting forth the matters to be addressed
                  at such meeting, and shall deliver or cause to be delivered to
                  the Beneficial Owner of the Class A Interest, concurrently
                  with the distribution thereof to any director, all reports and
                  any other information that is provided to such director.

                  (c) Standard of Care of the Members. No director shall be
personally liable to the Trust or the Trustee, the Depositor or any Beneficial
Owner for monetary damages for breach of fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the Trust
or the Beneficial Owners, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law or (iii) for any
transaction from which the director derived an improper personal benefit. No
amendment or repeal of this Section 6.01(c) shall adversely affect any right or
protection of a director existing hereunder in respect of any act or omission
occurring prior to such amendment or repeal.

                  Section 6.02. Management of Subsidiaries. (a) Appointment
Rights. Subject to Section 6.02(b), if, but only if, the Beneficial Owner of the
Class A Interest has appointed all of the directors that such Beneficial Owner
is entitled to appoint, such Beneficial Owner shall have the right to instruct
the Class A Designated Directors to cause the immediate appointment of one half
of the directors, or equivalent positions, of each subsidiary of the Trust other
than subsidiaries of Azurix Europe. In any subsidiary (the "Subject Subsidiary")
of the Trust where the Beneficial Owner of the Class A Interest has failed to
cause the appointment of all the directors (or equivalent positions) that such
Beneficial Owner has the right to appoint, the right of the directors of the
Subject Subsidiary who represent such Beneficial Owner to appoint directors in
any lower-tier subsidiary shall be suspended until the Beneficial Owner of the
Class A Interest causes the appointment of all of the directors of the Subject
Subsidiary that such Beneficial Owner is entitled to appoint.

                  (b) Dilution. If as a result of an offering of equity
interests by any subsidiary of the Trust, third parties have the right to
appoint and remove directors (or equivalent positions) 


                                       18
<PAGE>   22

of such subsidiary, such right shall correspondingly reduce the ability of the
representatives of the Beneficial Owner of the Class A Interest to cause the
appointment and removal of directors of such subsidiary, but not the ability of
the Beneficial Owner of the Class B Interest to cause the appointment of
directors. The foregoing dilution will be applied cumulatively if third party
equity investors in more than one subsidiary of the Trust have the right to
appoint and remove directors (or equivalent positions). By way of example, and
not by way of limitation, if (i) third party equity investors in Azurix are
given the right to appoint and remove ten percent (10%) of the board of
directors of Azurix and (ii) third party equity investors in Azurix Ltd. are
given the right to appoint and remove fifteen percent (15%) of the directors of
Azurix Ltd., then the Beneficial Owner of the Class A Interest would have the
right to appoint and remove forty percent (40%) of the board of directors of
Azurix and twenty-five percent (25%) of the directors of Azurix Ltd. The
Beneficial Owner of the Class A Interest, together with Persons who are not
Affiliates of the Beneficial Owner of the Class B Interest, shall at all times
have the right, by contract or statute, or both, to appoint and remove at least
one-half of the directors, or equivalent positions, of each subsidiary of the
Trust other than the subsidiaries of Azurix Europe.

                  (c) Delivery of Information. For each subsidiary of the Trust,
other than subsidiaries of Azurix Europe, that does not have a director (or
equivalent position) appointed by a representative of the Beneficial Owner of
the Class A Interest, such subsidiary shall deliver information to the
Beneficial Owner of the Class A Interest concurrently with delivery of such
information to the directors (or equivalent positions) of such subsidiary.

                  Section 6.03. Bankruptcy, Dissolution or Termination of a
Beneficial Owner. The incapacity, dissolution, termination or bankruptcy of a
Beneficial Owner shall not result in the termination or dissolution of the
Trust.

                  Section 6.04. Transfer of Beneficial Ownership. (a) To the
extent permitted by applicable law, and except as otherwise permitted in the
Transaction Documents, the Beneficial Owner of the Class A Interest shall not
have the right to transfer its Beneficial Interest in the Trust without the
prior written consent of the Beneficial Owner of the Class B Interest; provided,
however, the Beneficial Owner of the Class A Interest may transfer its
Beneficial Interest without such consent (i) following a Marlin Note Trigger
Event or (ii) to the extent contemplated by Section 11.07.

                  (b) Any transfers by the Beneficial Owner of the Class B
Interest shall be permitted only to the extent that such proposed transferor of
Class B Interest shall have delivered an opinion of Dewey Ballantine L.L.P.,
Vinson & Elkins L.L.P., Milbank, Tweed, Hadley & McCloy or any other nationally
recognized securities counsel to the effect that such transfer would not cause
the Trust or Marlin to be required to register as an investment company under
the Investment Company Act of 1940, as amended.

                  Section 6.05. Creditors of the Beneficial Owners. As is
provided in paragraph (b) of Section 3805 of the Act, no creditor of a
Beneficial Owner shall have any right to obtain possession of, or otherwise
exercise legal or equitable remedies with respect to, the Trust Estate.

                                   ARTICLE VII

               CONCERNING THE TRUSTEE AND WILMINGTON TRUST COMPANY

                  Section 7.01. General. (a) In the exercise or administration
of the Trust hereunder (and, without limitation, with respect to taking any
action pursuant to the terms of paragraph (a) of Section 9.01 hereof), the
Trustee at the expense of the Trust (to be paid by the Depositor in accordance
with Section 7.08) (i) may act directly or through agents or attorneys pursuant
to agreements entered into with any of them, and the Trustee shall not be liable
for the default or misconduct of such agents or attorneys if such agents or
attorneys shall have been selected by the Trustee with reasonable care; and (ii)
may consult with counsel, accountants and other skilled Persons to be selected
with reasonable care and employed by the Trustee, and it shall not be liable for
anything done, suffered or omitted in good faith by it in accordance with the
advice or opinion of any such counsel, accountants or other skilled Persons.

                  (b) Except as expressly provided herein, (i) in accepting the
Trust hereby created, Wilmington Trust Company acts solely as Trustee hereunder
and not in its individual capacity, and (ii) all Persons having any claim
against the Trust or the Trustee by reason of the transactions contemplated by
this Agreement shall look only to the Trust's property for payment or
satisfaction thereof.

                  (c) Except in accordance with the written instructions
furnished by the Beneficial Owners or the Board of Directors and except as
expressly provided herein, the Trustee shall have no duty to (i) see to any
recording or filing of any document, or (ii) see to the payment or discharge of
any tax, assessment or other governmental charge or any lien or encumbrance of
any kind owing with respect to, assessed or levied against any part of the
Trust.

                  (d) The Trustee shall manage the business and affairs of the
Trust in accordance with the terms of the Act and the Atlantic Water Transaction
Documents; provided, however, that the Trustee undertakes to perform only such
duties as are specifically set forth in this Agreement and as the Trustee may be
duly directed from time to time in writing by both Beneficial Owners or the
Board of Directors (acting within the scope of their authority as provided in
Section 6.01) and as the Trustee is required to in order to comply with the
other Atlantic Transaction Document. The Trustee shall not have any duty or
obligation to manage, control, use, sell, dispose of or otherwise deal with the
Trust or to otherwise take or refrain from taking any action under this
Agreement except as expressly required by the terms hereof (or of the other
Atlantic Water Transaction Document) or as expressly provided in written
instructions from the Beneficial Owners or the Board of Directors, and no
implied duties or obligations shall be read into this Agreement or the other
Atlantic Water Transaction Document against the Trustee. Wilmington Trust
Company nevertheless agrees that it will, at its own cost and expense (and not
at the expense of the Trust), promptly take all action as may be necessary to
discharge any Liens on any part of the Trust Estate which are attributable to
actions by or claims against Wilmington Trust Company that are not related to
the ownership of any part of the Trust Estate or the administration of the Trust
Estate or the transactions contemplated by this Agreement.


                                       20
<PAGE>   24

                  (e) The Trustee shall not be required to take any action under
this Agreement if the Trustee shall reasonably determine or shall have been
advised by counsel that such action is contrary to the terms of this Agreement
or is otherwise contrary to law.

                  (f) Subject to paragraph (a) of Section 9.01, whenever the
Trustee is unable to decide between alternative courses of action permitted or
required by the terms of this Agreement, or is unsure as to the application,
intent, interpretation or meaning of any provision hereof, the Trustee may give
notice (in such form as shall be appropriate under the circumstances) to the
Beneficial Owners or the Board of Directors (acting within the scope of their
authority as provided in Section 6.01) requesting written instructions as to the
course of action to be adopted, and, to the extent the Trustee acts in good
faith in accordance with any such appropriate instruction received, the Trustee
shall not be liable on account of such action or inaction to any Person. If the
Trustee shall not have received appropriate instructions within ten days of such
notice (or within such shorter period of time as reasonably may be specified in
such notice or may be necessary under the circumstances), it may, but shall be
under no duty to, take or refrain from taking such action which is consistent,
in its view, with this Agreement and as it shall deem to be in the best
interests of the Beneficial Owners, and the Trustee shall have no liability to
any Person for any such action or inaction.

                  (g) In no event whatsoever shall the Trustee be liable for any
representation, warranty, covenant, agreement, indebtedness or other obligation
of the Trust; provided, however, the foregoing shall, in no event whatsoever,
relieve the Trustee from any liability resulting from the Trustee's bad faith,
willful misconduct or gross negligence.

                  (h) The Trustee may rely upon and shall incur no liability to
anyone in acting upon any signature, instrument, notice, resolution, request,
consent, order, certificate, report, opinion, bond or other document or paper
reasonably believed by it to be genuine and reasonably believed by it to be
signed by the proper Persons. The Trustee may accept a certified copy of a
resolution of the board of directors or other governing body of any Person as
conclusive evidence that such resolution has been duly adopted by such body and
that the same is in full force and effect. As to any fact or matter the manner
of ascertainment of which is not specifically prescribed herein, the Trustee may
for all purposes hereof rely on a certificate, signed by the president or any
vice president or by the treasurer or any assistant treasurer or the secretary
or any assistant secretary (or equivalent position) of the relevant party, as to
such fact or matter, and such certificate shall constitute full protection to
the Trustee for any action taken or omitted to be taken by it in good faith
reliance thereon.

                  (i) The Trustee shall not be personally liable for any error
of judgment made in good faith.

                  (j) The Trustee shall not be required to take any action that
is inconsistent with the purposes of the Trust set forth in Section 1.04.

                  (k) No provision of this Agreement shall require the Trustee
to expend or risk its personal funds, or otherwise incur any financial liability
in the performance of its rights or powers hereunder, if the Trustee shall have
reasonable grounds for believing that repayment of 


                                       21
<PAGE>   25

such funds or adequate indemnity against such risk or liability is not
reasonably assured or provided to it.

                  (l) The Trustee may fully rely upon and shall have no
liability in connection with calculations or instructions forwarded to the
Trustee by both Beneficial Owners or the Board of Directors (acting within the
scope of their authority as provided in Section 6.01), unless the Trustee
determines that such calculations or instructions are in error; provided,
however, the Trustee shall have no obligation to make any such determination.

                  (m) The Trustee shall not have any responsibility or liability
for or with respect to the genuineness, value, sufficiency or validity of the
Trust Estate. The Trustee shall in no event assume or incur any liability, duty
or obligation to the Beneficial Owners or any other Person other than as
expressly provided for herein, and in no event shall the Trustee have any
implied duties or obligations hereunder.

                  (n) The Trustee shall incur no liability if, by reason of any
provision of any future law or regulation thereunder, the Trustee shall be
prevented or forbidden from doing or performing any act or thing which the terms
of this Agreement provide shall or may be done or performed.

                  Section 7.02. Acceptance of the Trust. Wilmington Trust
Company declares that it accepts the Trust hereby created and agrees to perform
its duties under this Agreement and the Act but only upon the terms of this
Agreement and as contemplated by the other Atlantic Water Transaction Document.

                  Section 7.03. Authority and Duties of the Trustee. (a) The
Trustee shall have the authority to act on behalf of the Trust to carry out the
purposes of the Trust and duties of the Trust under the Transaction Documents to
which the Trust or the Trustee is a party. The Trustee is authorized and
directed to execute and deliver this Agreement and the Participation Agreement
and each certificate or other document attached as an exhibit to or contemplated
by any such agreement, in such form as both Beneficial Owners shall approve
subject to the terms of the Transaction Documents, as evidenced conclusively by
the Trustee's execution thereof. The execution and delivery of, and performance
of the terms of, the Participation Agreement, and each certificate or other
document attached as an exhibit to or otherwise expressly contemplated by any
such agreement shall be deemed not to conflict with or constitute a breach or
default under this Agreement. The Trustee shall have only such authority and
duties as are expressly set forth in this Agreement. Upon the written
instruction of both Beneficial Owners, the Trustee shall amend the Certificate
of Trust or this Agreement, and shall execute, acknowledge, deliver, file or
record any document or instrument necessary or appropriate to carry out the
provisions of this Agreement, and the Participation Agreement in such form as is
provided to it; provided that such action does not alter the rights, powers and
duties of the Trustee as set forth in this Article VII.

                  (b) The Trustee shall have the power and authority to execute,
deliver, acknowledge and file all necessary documents and to maintain all
necessary records of the Trust as required by the Act.

<PAGE>   26

                  (c) The Trustee need not investigate any fact or matter stated
in any such document, but the Trustee, in its discretion, may make further
inquiry or investigation.

                  (d) The Trustee shall cause to be prepared and filed, such tax
returns and Periodic Filings relating to the Trust, and make such elections as
may from time to time be required or appropriate under any applicable Federal,
state or local statute or rule or regulation thereunder so as to maintain to the
extent possible the Trust's characterization for United States federal income
and any state or local tax purposes as provided in Section 11.08.

                  (e) The Trustee shall furnish to the Beneficial Owners,
promptly upon receipt thereof, duplicates or copies of all reports, notices,
requests, demands, certificates, financial statements and any other instruments
furnished to the Trustee hereunder, under the Participation Agreement, provided
that the Trustee shall not be required to furnish the Beneficial Owners with a
copy of any such materials if the Trustee determines that such party has
otherwise received such copies, unless such Beneficial Owner so requests.

                  (f) The Trustee shall cause to be kept, at its Corporate Trust
Office at Rodney Square North, 1100 North Market Street, Wilmington, Delaware
19890-0001, Attention: Corporate Trust Administration, a register or registers
for the purpose of registering the Beneficial Interest. The Trustee shall be the
registrar and shall, subject to the limitations set forth in Section 6.04,
provide for the registration of transfer of the Beneficial Interest of a
Beneficial Owner at the written request of such Beneficial Owner.

                  Section 7.04. Representations and Warranties of Wilmington
Trust Company. Wilmington Trust Company, in its individual capacity, hereby

                  (d) this Agreement has been duly executed and delivered by it
and (subject to the due execution and delivery by the other parties hereto)
constitutes a legal and binding obligation of it, enforceable against it in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereinafter in effect, relating to the enforcement of creditors' rights in

                  Section 7.05. Resignation of the Trustee. (a) The Trustee may

former Trustee and (ii) the ratification of the Transaction Documents by the
successor trustee, and no resignation of a Trustee shall be effective absent the
concurrent appointment of a successor Trustee.

                  (b) If a successor Trustee shall not have been appointed
within 60 days after such notice of resignation, the Trustee or either
Beneficial Owner may apply to any court of competent jurisdiction to appoint a
successor Trustee to act until such time as a successor shall have been
appointed as above provided.

                  (c) Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation to which substantially all the corporate trust
business of the Trustee may be transferred, shall, subject to such corporation
satisfying in all respects the requirements set forth in Section 7.05(a), be the
Trustee hereunder without further action.

                  (d) Upon the substitution of the Person serving as Trustee,
the Beneficial Owners and the successor Trustee shall file an amendment to the
Certificate of Trust with the Secretary of State of the State of Delaware in
accordance with the provisions of Section 3810 of the Act, indicating the change
in the Trustee.

                  Section 7.06. Liability. Wilmington Trust Company shall not be
personally liable under any circumstances, except (a) for its own bad faith,

expressly undertaken by it in the last sentence of Section 7.01(d) or (d) for
taxes, fees or other charges on, based on or measured by any fees, commissions
or compensation received by the Trustee in connection with any of the
transactions contemplated by this Agreement.
In particular, but not by way of limitation:

                  (i) the provisions of this Agreement, to the extent that they
         restrict the duties and liabilities of Wilmington Trust Company
         otherwise existing at law or in equity, 


                                       24
<PAGE>   28

         replace such other duties or liabilities of Wilmington Trust Company to
         the extent permissible under law or in equity; and

                  (ii) Wilmington Trust Company shall not be personally liable
         for the default or misconduct of the Beneficial Owners.

                  Section 7.07. Indemnification. The Depositor shall indemnify,
pay, protect, and hold harmless each of Wilmington Trust Company, its officers,
directors, employees, shareholders and agents (collectively the "Indemnified
Persons" or individually an "Indemnified Person") from and against any and all
liabilities, obligations, losses, damages, actions, judgments, suits,
proceedings, taxes, costs, expenses and disbursements of any kind or nature
whatsoever including, without limitation, all reasonable legal fees, third party
costs and expenses of defense, appeal and settlement of any and all suits,
actions, or proceedings instituted against such Indemnified Person or the Trust
and all reasonable third party costs of investigation in connection therewith
that may be imposed on, incurred by, or asserted against an Indemnified Person
relating to or arising out of any action or inaction on the part of the Trust or
an Indemnified Person in respect of the Trust. Notwithstanding the foregoing,
the Depositor shall not be liable to any such Indemnified Person for any of the
matters set forth in clauses (a) through (d) of the first sentence of Section
7.06. If any action, suit, or proceeding shall be pending against the Trust
and/or one or more Indemnified Person relating to or arising out of any action
or inaction of the Indemnified Person or Indemnified Persons, the Depositor
shall have the right to assume the defense of the Indemnified Person or
Indemnified Persons in which case such defense shall be conducted by counsel
chosen by the Depositor and reasonably satisfactory to the Indemnified Person or
Indemnified Persons; provided, however, that if an Indemnified Person is advised
by its counsel that due to actual or potential conflicting interests
representation by the same counsel would be inappropriate under applicable
standards of professional conduct, such Indemnified Person may, at the expense
of the Trust, employ separate counsel of its choice with respect to all matters
as to which such conflicting interest arise in any such action.

                  Section 7.08. Fees and Expenses. All reasonable out-of pocket

Indenture (provided, that the Trustee shall give notice to the Indenture Trustee
and the Depositor of the amount of such expenses, disbursements and advances due
and owing to the Trustee no later than three Business Days prior to each
semi-annual Payment Date) and, to the extent such amounts are not sufficient
therefor, second, by the Depositor. Wilmington Trust Company shall receive as
compensation for its services as Trustee hereunder such ordinary fees as are
separately agreed upon between Wilmington Trust Company and the Depositor in a
separate fee agreement. Wilmington Trust Company, in its capacity as Trustee
hereunder, shall be compensated reasonably for any extraordinary services
rendered by it hereunder as agreed to separately by the Depositor and the
Trustee.

                  Section 7.09. Litigation, Action Outside Delaware. (a) The
Trustee shall not be under any obligation to appear in, prosecute or defend any
action which in its opinion may 


                                       25
<PAGE>   29

require it to incur any out-of-pocket expense or any liability, unless it shall
be furnished with such reasonable security and indemnity against such expense or
liability as it may require, and any reasonable out-of-pocket costs of the
Trustee as a result of such actions shall be paid, first, from the
Administrative Expenses (as defined in the Indenture) distributed to the Trustee
by the Indenture Trustee under Section 5.09 of the Indenture, and, to the extent
such amounts are not sufficient therefor, second, by the Depositor.

                  (b) Notwithstanding anything contained herein to the contrary,
Wilmington Trust Company shall not be required to take any action in any
jurisdiction other than in the State of Delaware if the taking of such action
will (i) require the consent or approval or authorization or order of or the
giving of notice to, or the registration with or the taking of any other action
in respect of, any state or other governmental authority or agency of any
jurisdiction other than the State of Delaware; (ii) result in any fee, tax or
other governmental charge under the laws of any jurisdiction or any political
subdivisions thereof in existence on the date hereof other than the State of

bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect, relating to the enforcement of creditors' rights in general
and except as such enforceability may be limited by general principles of equity

to avoid rendering such other term or provision invalid or unenforceable, and
such modification shall be accomplished in the manner that most nearly preserves
the benefit of all the parties' bargain hereunder.

                  Section 11.07. Pledge of the Class A Interest to the Indenture
Trustee. The Beneficial Owner of the Class B Interest hereby expressly
acknowledges and consents to the pledge by the Beneficial Owner of the Class A
Interest of all such Beneficial Interest to the Indenture Trustee for the
benefit of the holders of the Marlin Senior Notes pursuant to the terms of the
Indenture and any subsequent transfers following foreclosure on such pledge in
accordance with the terms thereof. The Beneficial Owner of the Class B Interest
also expressly acknowledges and consents to any transfer by the Beneficial Owner
of the Class A Interest upon a failure by the Beneficial Owner of the Class B
Interest to make payment in accordance with Section 8(h) of the Remarketing
Agreement.

                  Section 11.08. Tax Matters. Each of the parties hereto
recognizes and intends that, for United States federal, state and local income
tax purposes,

                  (a) unless and until the Trust establishes additional classes
of Beneficial Interest or Enron transfers a portion or all of its Class B
Interest, the Trust will be disregarded as an entity separate from the Class B
Beneficial Owner pursuant to the United States Treasury Regulations
ss.ss.301.7701-1 through 301.7701-4 and comparable provisions of state and local
law, and all of the Trust's assets and income will be treated as owned by the
Class B Beneficial Owner whether or not pledged;

                  (b) if the Trust establishes additional classes of Beneficial
Interest or Enron transfers any of its Class B Interest, the Trust will
thereafter be treated as a partnership pursuant to the United States Treasury
Regulations ss.ss.301.7701-1 through 301.7701-3 and comparable provisions of
state and local law and all of the Trust's assets and income will be treated as
owned by such partnership whether or not pledged;

                  (c) the Class A Beneficial Interest will be treated as
indebtedness; and

                  (d) for such periods as the Trust is treated as a partnership
(and while so treated, in this Section 11.08, the Trust is referred to as the
"Partnership" and the Beneficial Owners of the Class B Interest are referred to
as ("Partners")), the following provisions shall apply:

                           (i) a tax capital account (the "Tax Capital Account")
                  shall be established and maintained for each Partner in
                  accordance with the provisions of Treasury Regulation
                  ss.1.704-1(b);

                           (ii) except as otherwise required by section 704 of
                  the Code and the Treasury Regulations thereunder, all items of
                  income, gain, loss, deduction and other tax items (as
                  determined for United States federal income tax purposes) for
                  each taxable year of the Partnership shall be allocated, to
                  the maximum extent possible, among the Partners in such shares
                  and proportions as will cause the 


                                       29
<PAGE>   33

                  positive balance in each Partner's Tax Capital Account as of
                  the end of such taxable year to be equal to the sum of the
                  amount of money and the fair market value of other property
                  that would be distributed to that Partner as of the end of
                  such taxable year if the Partnership were to dissolve and
                  liquidate as of the end of such taxable year;

                           (iii) Enron (or, if Enron is not then a Partner, such
                  Partner as the Partners may designate) shall serve as the tax
                  matters partner (as defined in section 6231 of the Code) of
                  the Partnership; and

                           (iv) the Partnership shall make an election to adjust
                  the basis of Partnership property pursuant to section 754 of
                  the Code and such other elections for United States federal
                  tax purposes as Enron may from time to time determine.

                  To the extent that any of the parties hereto is required to
report any item of income, gain, loss, deduction or credit relating to the Trust
for United States federal, state or local income tax purposes, such party shall
report such item in a manner consistent with the characterization intended by
this Section 11.08 and shall not take any contrary position on any tax return or
report relating to the United States federal, state or local income taxes or
take any other action which is inconsistent with such characterization.
Notwithstanding anything to the contrary herein, no party shall be obligated to
take a position subsequent to (A) a Final Determination to the contrary or (B) a
written opinion of independent, nationally-recognized tax counsel selected by
such party (such counsel and form of opinion to be reasonably satisfactory to
Enron) that no Reasonable Basis exists to take such position, which opinion
shall, solely in the case of a United States federal income Tax return, be based
on a Change in Law, provided, however, that a court decision described in clause
(IV) of the definition of "Change in Law" shall not constitute a Change in Law
if Enron provides to the relevant party a written opinion of independent,
nationally-recognized tax counsel selected by Enron (such counsel and form of
opinion to be reasonably satisfactory to such party) that, notwithstanding such
decision, such party's position is more likely than not to prevail if
challenged.

                  Section 11.09. Financial Statements. The Trust shall maintain
financial statements in accordance with GAAP and the Trustee shall deliver
copies thereof to each Beneficial Owner as follows:

                  (a) as soon as available and in any event within 45 days after
the end of the first, second and third fiscal quarters of Atlantic Water Trust,
an unaudited consolidated balance sheet of Atlantic Water Trust as of the end of
such quarter and the related consolidated statements of income and cash flows
for such quarter and for the portion of the fiscal year ending with the last day
of such quarter setting forth in comparative form corresponding unaudited
figures for the corresponding fiscal period of the preceding year, if any and

                  (b) as soon as available and in any event within 120 days
after the end of each fiscal year of Atlantic Water Trust, audited consolidated
financial statements of Atlantic Water Trust, prepared in accordance with U.S.
GAAP, together with an unqualified audit opinion of

of recognized national standing.

                  Section 11.10. Amendments, Waivers, Etc. This Agreement may
not be amended, discharged or terminated nor may any provision hereof be waived
unless such amendment, discharge, termination or waiver is in writing and signed
by Enron, Marlin and the Trustee.

                  Section 11.11. Limitation of Liability. It is expressly
understood and agreed by the parties hereto with respect to Marlin that (a) this
Agreement is executed and delivered by Wilmington Trust Company, not
individually or personally, but solely as trustee for Marlin, in the exercise of
the powers and authority conferred and vested in it under the Marlin Trust
Agreement, (b) each of the representations, undertakings and agreements herein
made on the part of Marlin is made and intended not as personal representations,
undertakings and agreements by Wilmington Trust but is made and intended for the
purpose of binding only Marlin, and (c) under no circumstances shall Wilmington
Trust Company be personally liable for the payment of any indebtedness or

representation, warranty or covenant made or undertaken by Marlin under this
Agreement or other related documents; provided, however, this Section 11.11
shall not limit the liability expressly assumed by Wilmington Trust Company
under this Agreement or the Marlin Trust Agreement.

                  Section 11.12. Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall be deemed to be an original, but
all such counterparts shall together constitute but one and the same instrument

                           documents or records which the relative Paying Agent,
                           the Registrar or the relative Transfer Agent, as the
                           case may be is obliged not to release by any law or
                           regulation; and/or

         (ii)     by notice in writing to the Issuer and the Guarantor require
                  each of them to make all subsequent payments in respect of the
                  Securities and Coupons to or to the order of the Trustee and
                  not to the Principal Paying Agent; with effect from the issue
                  of any such notice to the Issuer and the Guarantor and until
                  such notice is withdrawn proviso (i) to sub-clause (B) of this
                  Clause 2 relating to the Original Bonds and any similar
                  provisos relating to any Further Securities shall cease to
                  have effect.

         FURTHER ISSUES

(D)      (i)      The Issuer shall be at liberty from time to time (but
                  subject always to the provisions of these presents) without
                  the consent of the Holders or Couponholders to create and
                  issue further bonds or notes (whether in bearer or registered
                  form) either (a) ranking pari passu in all respects (or in all
                  respects save for the first payment of interest thereon), and
                  so that the same shall be consolidated and form a single
                  series, with the Original Bonds and/or the Further Securities
                  of any series or (b) upon such terms as to ranking, interest,
                  conversion, redemption and otherwise as the Issuer may at the
                  time of issue thereof determine.

         (ii)     Any further bonds or notes which are to be created and issued
                  pursuant to the provisions of paragraph (i) above so as to
                  form a single series with the Original Bonds and/or the
                  Further Securities of any series shall be constituted by a
                  trust deed supplemental to this Trust Deed and any other
                  further bonds or notes which are to be created and issued
                  pursuant to the provisions of paragraph (i) above may (subject
                  to the consent of the Trustee) be constituted by a trust deed
                  supplemental to this Trust Deed. In any such case the Issuer
                  and the Guarantor shall prior to the issue of any further
                  bonds or notes to be so constituted (being Further Securities)
                  execute and deliver to the Trustee a trust deed supplemental
                  to this Trust Deed (in relation to which all applicable stamp
                  duties or other documentation fees, duties or taxes have been
                  paid and, if applicable, duly stamped or denoted accordingly)
                  and containing a covenant by the Issuer in the form mutatis
                  mutandis of Clause 2(B) in relation to the principal, premium
                  (if any) and interest in respect of such Further Securities
                  and such other provisions (whether or not corresponding to any
                  of the provisions contained in this Trust Deed) as the Trustee
                  shall require.

         (iii)    A memorandum of every such supplemental trust deed shall be
                  endorsed by the Trustee on this Trust Deed and by the Issuer
                  and the Guarantor on their duplicates of this Trust Deed.

         (iv)     Whenever it is proposed to create and issue any further bonds
                  or notes to be constituted by a trust deed supplemental to
                  this Trust Deed the Issuer shall give to the Trustee not less
                  than 14 days' notice in writing of its intention so to do
                  stating the amount of further bonds or notes proposed to be
                  created and issued.

(E)      Any Further Securities not forming a single series with the Original
         Bonds or Further Securities of any series shall form a separate series
         and accordingly, unless for any purpose the Trustee in its absolute
         discretion shall otherwise determine, the provisions of sub-clause (C)
         of this Clause and of Clauses 4 to 22 (both inclusive) and 23(B) and
         the Third and Fourth Schedules shall apply mutatis mutandis separately
         and independently to each series of the Securities and in such Clauses
         and Schedules the expressions "SECURITIES", "HOLDERS", "COUPONS",
         "COUPONHOLDERS" and "TALONS" shall be construed accordingly.

         depositary shall hold the same for the account of the persons who would
         otherwise be entitled to receive the Original Bonds in definitive form
         ("DEFINITIVE ORIGINAL BONDS") (as notified to such depositary by
         Midland Bank plc on behalf of the Managers of the issue of the Original
         Bonds) and the successors in title to such persons as appearing in the
         records of Euroclear and Cedelbank for the time being.

         shall be signed manually or in facsimile by a person duly authorised by
         the Issuer on behalf of the Issuer and shall be authenticated by or on

         Bond so executed and authenticated shall be a binding and valid
         obligation of the Issuer and title thereto shall pass by delivery.

(C)      The Issuer shall issue the Original Permanent Global Bond in exchange
         for the Original Temporary Global Bond in accordance with the
         provisions thereof. The Original Permanent Global Bond shall be printed

         authenticated by or on behalf of the Principal Paying Agent. The
         Original Permanent Global Bond so executed and authenticated shall be a
         binding and valid obligation of the Issuer and title thereto shall pass
         by delivery.

(D)      The Issuer shall issue the Definitive Original Bonds (together with the
         unmatured Original Coupons attached) in exchange for the Original
         Permanent Global Bond in accordance with the provisions thereof.

         bearer in the respective forms or substantially in the respective forms
         set out in the Second Schedule and the Definitive Original Bonds shall

<PAGE>   15

(F)      The Definitive Original Bonds shall be signed manually or in facsimile
         by two of the Directors of the Issuer on behalf of the Issuer and shall
         be authenticated by or on behalf of the Principal Paying Agent.

(G)      The Issuer may use the facsimile signature of any person who at the
         date such signature is affixed is a Director of the Issuer or is a
         person duly authorised by the Issuer as referred to in sub-clauses (B)
         and (C) above notwithstanding that at the time of issue of any of the
         Definitive Original Bonds, the Original Temporary Global Bond or the
         Original Permanent Global Bond, as the case may be, he may have ceased
         for any reason to be the holder of such office or to be so authorised.
         The Original Coupons shall not be signed. The Definitive Original
         Bonds, the Original Temporary Global Bond and the Original Permanent
         Global Bond so executed and authenticated, and the Original Coupons,
         upon execution and authentication of the relevant Definitive Original
         Bonds, shall be binding and valid obligations of the Issuer.

         other fees, duties and taxes, including interest and penalties, payable

         with the execution and delivery of these presents and the constitution
         and original issue of the Securities and the Coupons and (ii) in any
         jurisdiction on or in connection with any action taken by or on behalf

         EACH of the Issuer and the Guarantor severally covenants with the
         Trustee that it will comply with and perform and observe all the
         provisions of these presents which are expressed to be binding on it.
         The Conditions shall be binding on the Issuer, the Guarantor, the
         Holders and the Couponholders. The Trustee shall be entitled to enforce
         the obligations of the Issuer and the Guarantor under the Securities
         and the Coupons as if the same were set out and contained in the trust
         deeds constituting the same, which shall be read and construed as one
         document with the Securities and the Coupons. The Trustee shall hold
         the benefit of this covenant upon trust for itself and the Holders and
         the Couponholders according to its and their respective interests.

6.       CANCELLATION OF SECURITIES AND RECORDS

         which, being mutilated or defaced, have been surrendered and replaced

                  date of the Coupons attached thereto or surrendered therewith;

         (f)      the aggregate principal amounts of Securities and the
                  aggregate amounts in respect of Coupons which have been so
                  exchanged or surrendered and replaced and the serial numbers
                  of such Securities in definitive form and the total number

         possible and in any event within four months after the date of such
         redemption, purchase, cancellation, payment, exchange, replacement or

         unexchanged and (iii) that such records and Coupons (if any) shall be
         made available to the Trustee at all reasonable times.

7.       GUARANTEE

(A)      THE Guarantor hereby irrevocably and unconditionally guarantees to the
         Trustee the due and punctual payment in accordance with the provisions
         of these presents of the principal of and premium (if any) and interest
         on the Securities and of any other amounts payable by the Issuer under
         these presents.

(B)      If the Issuer fails for any reason whatsoever punctually to pay any
         such principal, premium, interest or other amount, the Guarantor shall
         cause each and every such payment to be made as if the Guarantor
         instead of the Issuer were expressed to be the primary obligor under
         these presents and not merely a surety (but without affecting the
         nature of the Issuer's obligations) to the intent that the holder of
         the relevant Security or Coupon or the Trustee (as the case may be)
         shall receive the same amounts in respect of principal, premium,
         interest or such other amount as would have been receivable had such
         payments been made by the Issuer.

(C)      If any payment received by the Trustee or any Holder or Couponholder
         under the provisions of these presents shall (whether on the subsequent
         bankruptcy, insolvency or corporate reorganisation of the Issuer or,
         without limitation, on any other event) be avoided or set aside for any
         reason, such payment shall not be considered as discharging or
         diminishing the liability of the Guarantor and this guarantee shall
         continue to apply as if such payment had at all times remained owing by
         the Issuer and the Guarantor shall indemnify the Trustee and the
         Holders and/or Couponholders (as the case may be) in respect thereof
         PROVIDED THAT the obligations of the Issuer and/or the Guarantor under
         this sub-clause shall, as regards each payment made to the Trustee or
         any Holder or Couponholder which is avoided or set aside, be contingent
         upon such payment being reimbursed to the Issuer or other persons
         entitled through the Issuer.

(D)      The Guarantor hereby agrees that its obligations under this Clause
         shall be unconditional and that the Guarantor shall be fully liable
         irrespective of the validity, regularity, legality or enforceability
         against the Issuer of, or of any defence or counter-claim whatsoever
         available to the Issuer in relation to, its obligations under these
         presents, whether or not any action has been taken to enforce the same
         or any judgment obtained against the Issuer, whether or not any of the
         other provisions of these presents have been modified, whether or not
         any time, indulgence, waiver, authorisation or consent has been granted
         to the Issuer by or on behalf of the Holders or the Couponholders or
         the Trustee, whether or not any determination has been made by the
         Trustee pursuant to Clause 19(A), whether or not there have been any
         dealings or transactions between the Issuer, any of the Holders or
         Couponholders or the Trustee, whether or not the Issuer has been
         dissolved, liquidated, merged, consolidated, bankrupted or has changed
         its status, functions, control or ownership, whether or not the Issuer
         has been prevented from making payment by foreign exchange provisions
         applicable at its place of registration or incorporation and whether or
         not any other circumstances have occurred which might otherwise
         constitute a legal or equitable discharge of or defence to a guarantor.
         Accordingly the validity of this guarantee shall not be affected by
         reason of any invalidity, irregularity, illegality or unenforceability
         of all or any of the obligations of the Issuer under these presents and
         this guarantee shall not be discharged nor shall the liability of the
         Guarantor under these presents be affected by any act, thing or
         omission or means whatever whereby its liability would not have been
         discharged if it had been the principal debtor.



                                       14
<PAGE>   18

(E)      Without prejudice to the provisions of Clause 9(A) the Trustee may
         determine from time to time whether or not it will enforce this
         guarantee which it may do without making any demand of or taking any
         proceedings against the Issuer and may from time to time make any
         arrangement or compromise with the Guarantor in relation to this
         guarantee which the Trustee may consider expedient in the interests of
         the Holders.

(F)      The Guarantor waives diligence, presentment, demand of payment, filing
         of claims with a court in the event of dissolution, liquidation, merger
         or bankruptcy of the Issuer, any right to require a proceeding first
         against the Issuer, protest or notice with respect to these presents or
         the indebtedness evidenced thereby and all demands whatsoever and
         covenants that this guarantee shall be a continuing guarantee, shall
         extend to the ultimate balance of all sums payable and obligations owed
         by the Issuer under these presents, shall not be discharged except by
         complete performance of the obligations in these presents and is
         additional to, and not instead of, any security or other guarantee or
         indemnity at any time existing in favour of any person, whether from
         the Guarantor or otherwise.

(G)      If any moneys shall become payable by the Guarantor under this
         guarantee the Guarantor shall not, so long as the same remain unpaid,
         without the prior written consent of the Trustee:

         (i)      in respect of any amounts paid by it under this guarantee,
                  exercise any rights of subrogation or contribution or, without
                  limitation, any other right or remedy which may accrue to it
                  in respect of or as a result of any such payment; or

         (ii)     in respect of any other moneys for the time being due to the
                  Guarantor by the Issuer, claim payment thereof or exercise any
                  other right or remedy;

         (including in either case claiming the benefit of any security or right
         of set-off or, on the liquidation of the Issuer, proving in competition
         with the Trustee). If, notwithstanding the foregoing, upon the
         bankruptcy, insolvency or liquidation of the Issuer, any payment or
         distribution of assets of the Issuer of any kind or character, whether
         in cash, property or securities, shall be received by the Guarantor
         before payment in full of all amounts payable under these presents
         shall have been made to the Holders, the Couponholders and the Trustee,
         such payment or distribution shall be received by the Guarantor on
         trust to pay the same over immediately to the Trustee for application
         in or towards the payment of all sums due and unpaid under these
         presents in accordance with Clause 10.

(H)      The obligations of the Guarantor under these presents are direct,
         unconditional and, subject to the provisions of Condition 3, unsecured
         obligations of the Guarantor and, save for such exceptions as may be
         provided by applicable laws and subject to Condition 3, at all times
         rank at least equally with all its other outstanding unsecured and
         unsubordinated obligations, present and future.

8.       ENFORCEMENT

(A)      THE Trustee may at any time, at its discretion and without notice, take

         relation to each of the Issuer and the Guarantor to enforce their
         respective obligations under these presents.



                                       15
<PAGE>   19

(B)      Proof that as regards any specified Security or Coupon the Issuer or
         the Guarantor (as the case may be) has made default in paying any
         amount due in respect of such Security or Coupon shall (unless the
         contrary be proved) be sufficient evidence that the same default has
         been made as regards all other Securities or Coupons (as the case may
         be) in respect of which the relevant amount is due and payable.

(C)      References in the provisions of any trust deed supplemental to this
         Trust Deed corresponding to provisos (ii) and (iii) to Clause 2(B) to
         "the rate aforesaid" shall, in respect of any Securities bearing
         interest at a floating or variable rate, in the event of such
         Securities having become due and repayable, with effect from the expiry
         of the interest period during which such Securities become due and
         repayable, be construed as references to a rate of interest calculated
         mutatis mutandis in accordance with the Conditions except that no
         notices need be published in respect thereof.

9.       ACTION, PROCEEDINGS AND INDEMNIFICATION

(A)      THE Trustee shall not be bound to take any action in relation to these
         presents (including but not limited to the giving of any certification
         or notice pursuant to Condition 10 or the taking of any proceedings
         and/or other action mentioned in Clause 8(A)) unless respectively
         directed or requested to do so (i) by an Extraordinary Resolution or
         (ii) in writing by the holders of at least one-quarter in principal
         amount of the Securities then outstanding and in either case then only
         if it shall be indemnified to its satisfaction against all Liabilities
         to which it may render itself liable or which it may incur by so doing.

(B)      Only the Trustee may enforce the provisions of these presents. No
         Holder or Couponholder shall be entitled to proceed directly against
         the Issuer or the Guarantor to enforce the performance of any of the
         provisions of these presents unless the Trustee having become bound as
         aforesaid to take proceedings fails to do so within a reasonable period
         and such failure shall be continuing.

10.      APPLICATION OF MONEYS

         ALL moneys received by the Trustee under these presents shall, unless
         and to the extent attributable in the opinion of the Trustee to a
         particular series of the Securities, be apportioned pari passu and
         rateably between each series of the Securities, and all moneys received
         by the Trustee under these presents to the extent attributable in the
         opinion of the Trustee to a particular series of the Securities or
         which are apportioned to such series as aforesaid (including any moneys
         which represent principal, premium or interest in respect of Securities
         or Coupons which have become void under Condition 9) shall be held by
         the Trustee upon trust to apply them (subject to Clause 12):

         FIRST in payment or satisfaction of all amounts then due and unpaid
         under Clauses 15 and/or 16(J) to the Trustee and/or any Appointee;

         SECONDLY in or towards payment pari passu and rateably of all
         principal, premium (if any) and interest then due and unpaid in respect
         of the Securities of that series;

         THIRDLY in or towards payment pari passu and rateably of all principal,
         premium (if any) and interest then due and unpaid in respect of the
         Securities of each other series; and



                                       16
<PAGE>   20

         FOURTHLY in payment of the balance (if any) to the Issuer or, if moneys
         were received from the Guarantor, the Guarantor (without prejudice to,
         or liability in respect of, any question as to how such payment to the
         Issuer shall be dealt with as between the Issuer, the Guarantor and any
         other person).

         Without prejudice to this Clause 10, if the Trustee holds any moneys
         which represent principal, premium (if any) or interest in respect of
         Securities which have become void or in respect of which claims have
         been prescribed under Condition 9, the Trustee will hold such moneys on
         the above trusts.

11.      NOTICE OF PAYMENTS

         THE Trustee shall give notice to the relevant Holders in accordance
         with Condition 14 of the day fixed for any payment to them under Clause
         10. Such payment may be made in accordance with Condition 5 and any
         payment so made shall be a good discharge to the Trustee.

12.      INVESTMENT BY TRUSTEE

(A)      IF the amount of the moneys at any time available for the payment of
         principal, premium (if any) and interest in respect of the Securities
         under Clause 10 shall be less than 10 per cent. of the amount then due
         in respect of the Securities then outstanding the Trustee may at its
         discretion invest such moneys in some or one of the investments
         authorised below. The Trustee at its discretion may vary such
         investments and may accumulate such investments and the resulting
         income until the accumulations, together with any other funds for the
         time being under the control of the Trustee and available for such
         purpose, amount to at least 10 per cent. of the amount then due in
         respect of the Securities then outstanding and then such accumulations
         and funds (after deduction of, or provision for, applicable taxes)
         shall be applied under Clause 10.

(B)      Any moneys which under the trusts of these presents ought to or may be
         invested by the Trustee may be invested in the name or under the
         control of the Trustee in any investments or other assets in any part
         of the world whether or not they produce income or by placing the same
         on deposit in the name or under the control of the Trustee at such bank
         or other financial institution and in such currency as the Trustee may
         think fit. If that bank or institution is the Trustee or a Subsidiary,
         holding or associated company of the Trustee, it need only account for
         an amount of interest equal to the amount of interest which would, at
         then current rates, be payable by it on such a deposit to an
         independent customer. The Trustee may at any time vary any such
         investments for or into other investments or convert any moneys so
         deposited into any other currency and shall not be responsible for any
         loss resulting from any such investments or deposits, whether due to
         depreciation in value, fluctuations in exchange rates or otherwise.

13.      PARTIAL PAYMENTS

         UPON any payment under Clause 10 (other than payment in full against
         surrender of a Security or Coupon) the Security or Coupon in respect of
         which such payment is made shall be produced to the Trustee or the
         Paying Agent by or through whom such payment is made and the Trustee
         shall or shall cause such Paying Agent to enface thereon a memorandum
         of the amount and the date of payment but the Trustee may in any
         particular case or generally in 



                                       17
<PAGE>   21

         relation to Registered Securities dispense with such production and
         enfacement upon such indemnity being given as it shall think
         sufficient.

14.      COVENANTS BY THE ISSUER AND THE GUARANTOR

         SO long as any of the Securities remains outstanding (or, in the case
         of paragraphs (viii), (ix), (xiii), (xiv), (xvi) and (xviii), so long
         as any of the Securities or Coupons remains liable to prescription or,
         in the case of paragraph (xv), until the expiry of a period of 30 days
         after the Relevant Date in respect of the payment of principal in
         respect of all such Securities remaining outstanding at such time) each

                  certificates, information and evidence as it shall reasonably
                  require and in such form as it shall require (including
                  without limitation the procurement by the Issuer or the
                  Guarantor (as the case may be) of all such certificates called
                  for by the Trustee pursuant to Clause 16(C)) for the purpose
                  of the discharge or exercise of the duties, trusts, powers,
                  authorities and discretions vested in it under these presents

                  requirements and all requirements for the time being of The
                  Stock Exchange;

         (iv)     at all times keep and procure its Subsidiaries to keep proper
                  books of account and, at any time after the occurrence of an
                  Event of Default or a Potential Event of Default or it the
                  Trustee certifies in writing to the Issuer or the Guarantor
                  that it has reasonable grounds to believe that an Event of
                  Default or a Potential Event of Default has or may have
                  occurred and so far as permitted by applicable law allow and
                  procure its Subsidiaries to allow the Trustee and any person
                  appointed by the Trustee to whom the Issuer, the Guarantor or
                  the relevant Subsidiary (as the case may be) shall have no
                  reasonable objection, upon reasonable notice, free access to
                  such books of account at all times during normal business
                  hours for the purpose of the discharge or exercise of the
                  duties, trusts, powers, authorities and discretions vested in
                  it under these presents or by operation of law;

         (v)      send to the Trustee (in addition to any copies to which it may
                  be entitled as a holder of any securities of the Issuer or the
                  Guarantor) two copies in English of every balance sheet,
                  profit and loss account, report, circular and notice of
                  general meeting and every other document issued or sent to its
                  shareholders together with any of the foregoing, and every
                  document issued or sent to holders of securities other than
                  its shareholders (including the Holders) as soon as
                  practicable after the issue or publication thereof;

         (vi)     forthwith give notice in writing to the Trustee of the coming
                  into existence of any Security Interest which would require
                  any security to be given in respect of any 



                                       18

                  period a certificate signed by two Directors of the Issuer and
                  two Directors of the Guarantor to the effect that as at a date
                  not more than seven days before delivering such certificate
                  (the "CERTIFICATION DATE") there did not exist and had not
                  existed since the certification date of the previous
                  certificate (or in the case of the first such certificate the
                  date hereof) any Event of Default or any Potential Event of

                  all such further acts and things as may be necessary at any
                  time or times in the reasonable opinion of the Trustee to give
                  effect to these presents;

         (ix)     at all times maintain an Agent Bank, Reference Banks, Paying

(A)      THE Issuer shall pay to the Trustee remuneration for its services as
         trustee as from the date of this Trust Deed, such remuneration to be at
         such rate as may from time to time be agreed between the Issuer and the
         Trustee. Such remuneration shall be payable in advance on 30th March in
         each year, the first such payment to be made on the date hereof. The
         rate of remuneration in force from time to time may upon the final
         redemption of the whole of the Securities of any series be reduced by
         such amount as shall be agreed between the Issuer and the Trustee, such
         reduced remuneration to be calculated from such date as shall be agreed
         as aforesaid. Such remuneration shall accrue from day to day and be
         payable (in priority to payments to the Holders and Couponholders) up
         to and including the date when, all the Securities having become due
         for redemption, the redemption moneys and interest thereon to the date
         of redemption have been paid to the Principal Paying Agent and, where
         applicable, the Registrar or, as the case may be, the Trustee PROVIDED
         THAT if upon due presentation 



                                       22

         of any Security or Coupon or any cheque payment of the moneys due in
         respect thereof is improperly withheld or refused, remuneration will
         commence again to accrue.

(B)      In the event of the occurrence of an Event of Default or a Potential
         Event of Default or the Trustee considering it expedient or necessary
         or being requested by the Issuer or the Guarantor to undertake duties
         which the Trustee and the Issuer agree to be of an exceptional nature
         or otherwise outside the scope of the normal duties of the Trustee
         under these presents the Issuer shall pay to the Trustee such
         additional remuneration as shall be agreed between them.

(C)      The Issuer shall in addition pay to the Trustee an amount equal to the
         amount of any value added tax or similar tax chargeable in respect of
         its remuneration under these presents.

(D)      In the event of the Trustee and the Issuer failing to agree:

         (1)      (in a case to which sub-clause (A) above applies) upon the
                  amount of the remuneration; or

         (2)      (in a case to which sub-clause (B) above applies) upon whether
                  such duties shall be of an exceptional nature or otherwise
                  outside the scope of the normal duties of the Trustee under
                  these presents, or upon such additional remuneration,

         such matters shall be determined by a merchant or investment bank
         (acting as an expert and not as an arbitrator) selected by the Trustee
         and approved by the Issuer or, failing such approval, nominated (on the
         application of the Trustee) by the President for the time being of The
         Law Society of England and Wales (the expenses involved in such
         nomination and the fees of such merchant or investment bank being
         payable by the Issuer) and the determination of any such merchant or
         investment bank shall be final and binding upon the Trustee and the
         Issuer.

(E)      The Issuer shall also pay or discharge all Liabilities incurred by the
         Trustee in relation to the preparation and execution of, the exercise
         of its powers and the performance of its duties under, and in any other
         manner in relation to, these presents, including but not limited to
         travelling expenses and any stamp, issue, registration, documentary and
         other taxes or duties paid or payable by the Trustee in connection with
         any action taken or contemplated by or on behalf of the Trustee for
         enforcing, or resolving any doubt concerning, or for any other purpose
         in relation to, these presents.

(F)      All amounts payable pursuant to sub-clause (E) above and/or Clause
         16(J) shall be payable by the Issuer on the date specified in a demand
         by the Trustee and in the case of payments actually made by the Trustee
         prior to such demand shall (if not paid within 15 days after such
         demand and the Trustee so requires) carry interest at the rate of two
         per cent. per annum above the Base Rate from time to time of Midland
         Bank plc from the date specified in such demand, and in all other cases
         shall (if not paid on the date specified in such demand or, if later,
         within 15 days after such demand and, in either case, the Trustee so
         requires) carry interest at such rate from the date specified in such
         demand. All remuneration payable to the Trustee shall carry interest at
         such rate from the due date therefor.

         force and effect notwithstanding such discharge.

                  any such letter, telex, telegram, facsimile transmission or
                  cable although the same shall contain some error or shall not
                  be authentic.

         (C)      The Trustee may call for and shall be at liberty to accept as

                  Trustee to be of good repute and the Trustee shall not be
                  responsible for or required to insure against any Liability
                  incurred in connection with any such holding or deposit and

                  Securities for Bearer Securities.

                  the execution of any documents comprised or referred to in

                  Event of Default or any Potential Event of Default has
                  happened and, until it shall have actual knowledge or express
                  notice pursuant to these presents to

<PAGE>   28

                  the contrary, the Trustee shall be entitled to assume that no
                  Event of Default or Potential Event of Default has happened
                  and that each of the Issuer and the Guarantor is observing and
                  performing all its obligations under these presents.

         (G)      Save as expressly otherwise provided in these presents, the
                  Trustee shall have absolute and uncontrolled discretion as to
                  the exercise or non-exercise of its trusts, powers,
                  authorities and discretions under these presents (the exercise
                  or non-exercise of which as between the Trustee and the
                  Holders and Couponholders shall be conclusive and binding on
                  the Holders and Couponholders) and shall not be responsible
                  for any Liability which may result from their exercise or
                  non-exercise and in particular the Trustee shall not be bound
                  to act at the request or direction of the Holders or otherwise
                  under any provision of these presents or to take at such
                  request or direction or otherwise any other action under any
                  provision of these presents, without prejudice to the
                  generality of Clause 9(A), unless it shall first be
                  indemnified to its satisfaction against all Liabilities to
                  which it may render itself liable or which it may incur by so
                  doing.

         (H)      The Trustee shall not be liable to any person by reason of
                  having acted upon any Extraordinary Resolution in writing or
                  any Extraordinary Resolution or other resolution purporting to
                  have been passed at any meeting of the Holders of Securities
                  of all or any series in respect whereof minutes have been made
                  and signed even though subsequent to its acting it may be
                  found that there was some defect in the constitution of the
                  meeting or the passing of the resolution or (in the case of an
                  Extraordinary Resolution in writing) that not all Holders had
                  signed the Extraordinary Resolution or that for any reason the
                  resolution was not valid or binding upon such Holders and the
                  relative Couponholders.

         (I)      The Trustee shall not be liable to any person by reason of
                  having accepted as valid or not having rejected any Security
                  or Coupon purporting to be such and subsequently found to be
                  forged or not authentic.

         (J)      Subject to Clause 17 and without prejudice to the right of
                  indemnity by law given to trustees, the Issuer, failing whom
                  the Guarantor, shall indemnify the Trustee and every Appointee
                  and keep it or him indemnified against all Liabilities to
                  which it or he may be or become subject or which may be
                  incurred by it or him in the execution or purported execution
                  of any of its or his trusts, powers, authorities and
                  discretions under these presents or its or his functions under
                  any such appointment or in respect of any other matter or
                  thing done or omitted in any way relating to these presents or
                  any such appointment.

         (K)      Any consent or approval given by the Trustee for the purposes
                  of these presents may be given on such terms and subject to
                  such conditions (if any) as the Trustee thinks fit and
                  notwithstanding anything to the contrary in these presents may
                  be given retrospectively.

         (L)      The Trustee shall not (unless and to the extent ordered so to
                  do by a court of competent jurisdiction) be required to
                  disclose to any Holder or Couponholder any information
                  (including, without limitation, information of a confidential,
                  financial or price sensitive nature) made available to the
                  Trustee by the Issuer or the Guarantor or 




                                       25

                  any other person in connection with these presents and no
                  Holder or Couponholder shall be entitled to take any action to
                  obtain from the Trustee any such information.

         (M)      Where it is necessary or desirable for any purpose in
                  connection with these presents to convert any sum from one
                  currency to another it shall (unless otherwise provided by
                  these presents or required by law) be converted at such rate
                  or rates, in accordance with such method and as at such date
                  for the determination of such rate of exchange, as may be
                  agreed by the Trustee in consultation with the Issuer or the
                  Guarantor as relevant and any rate, method and date so agreed
                  shall be binding on the Issuer, the Guarantor, the Holders and
                  the Couponholders.

         (N)      The Trustee may certify whether or not any of the conditions,
                  events and acts set out in sub-paragraphs (b), (c), (e), (f),
                  (g) and (h) of Condition 10 (each of which conditions, events
                  and acts shall, unless in any case the Trustee in its absolute
                  discretion shall otherwise determine, for all the purposes of
                  these presents be deemed to include the circumstances
                  resulting therein and the consequences resulting therefrom) is
                  in its opinion materially prejudicial to the interests of the
                  Holders and any such certificate shall be conclusive and
                  binding upon the Issuer, the Guarantor, the Holders and the
                  Couponholders.

         (O)      The Trustee as between itself and the Holders and
                  Couponholders may determine all questions and doubts arising
                  in relation to any of the provisions of these presents. Every
                  such determination, whether or not relating in whole or in
                  part to the acts or proceedings of the Trustee, shall be
                  conclusive and shall bind the Trustee and the Holders and
                  Couponholders.

         (P)      In connection with the exercise by it of any of its trusts,
                  powers, authorities and discretions under these presents
                  (including, without limitation, any modification, waiver,
                  authorisation, determination or substitution), the Trustee
                  shall have regard to the general interests of the Holders as a
                  class and shall not have regard to any interests arising from
                  circumstances particular to individual Holders or
                  Couponholders (whatever their number) and, in particular but
                  without limitation, shall not have regard to the consequences
                  of any such exercise for individual Holders or Couponholders
                  (whatever their number) resulting from their being for any
                  purpose domiciled or resident in, or otherwise connected with,
                  or subject to the jurisdiction of, any particular territory or
                  any political sub-division thereof and the Trustee shall not
                  be entitled to require, nor shall any Holder or Couponholder
                  be entitled to claim, from the Issuer, the Guarantor, the
                  Trustee or any other person any indemnification or payment in
                  respect of any tax consequence of any such exercise upon
                  individual Holders or Couponholders except to the extent
                  already provided for in Condition 8 and/or any undertaking
                  given in addition thereto or in substitution therefor under
                  these presents.

         (Q)      Any trustee of these presents being a lawyer, accountant,
                  broker or other person engaged in any profession or business
                  shall be entitled to charge and be paid all usual professional
                  and other charges for business transacted and acts done by him
                  or his firm in connection with the trusts of these presents
                  and also his reasonable charges in addition to disbursements
                  for all other work and business done and all time spent by him
                  or his firm in connection with matters arising in connection
                  with these presents.

         (R)      The Trustee may whenever it thinks fit and, if appropriate,
                  after consultation with the Issuer and/or the Guarantor
                  delegate by power of attorney or otherwise to any person or
                  persons or fluctuating body of persons (whether being a joint
                  trustee of these presents or not) all or any of its trusts,
                  powers, authorities and discretions under these presents. Such
                  delegation may be made upon such terms (including power to
                  sub-delegate) and subject to such conditions and regulations
                  as the Trustee may in the interests of the Holders think fit.
                  Provided that the Trustee has exercised reasonable care in the
                  selection of such delegate, the Trustee shall not be under any
                  obligation to supervise the proceedings or acts of any such
                  delegate or sub-delegate or be in any way responsible for any
                  Liability incurred by reason of any misconduct or default on
                  the part of any such delegate or sub-delegate. The Trustee
                  shall within a reasonable time after any such delegation or
                  any renewal, extension or termination thereof give notice
                  thereof to the Issuer.

         (S)      The Trustee may in the conduct of the trusts of these presents
                  instead of acting personally employ and pay an agent (whether
                  being a lawyer or other professional person) to transact or
                  conduct, or concur in transacting or conducting, any business
                  and to do, or concur in doing, all acts required to be done in
                  connection with these presents (including the receipt and
                  payment of money). Provided that the Trustee has exercised
                  reasonable care in the selection of such agent, the Trustee
                  shall not be in any way responsible for any Liability incurred
                  by reason of any misconduct or default on the part of any such
                  agent or be bound to supervise the proceedings or acts of any
                  such agent.

         (T)      The Trustee shall not be responsible for the execution,
                  delivery, legality, effectiveness, adequacy, genuineness,
                  validity, performance, enforceability or admissibility in
                  evidence of these presents or any other document relating or
                  expressed to be supplemental thereto and shall not be liable
                  for any failure to obtain any licence, consent or other
                  authority for the execution, delivery, legality,
                  effectiveness, adequacy, genuineness, validity, performance,
                  enforceability or admissibility in evidence of these presents
                  or any other document relating or expressed to be supplemental
                  thereto.

         (U)      The Trustee shall not at any time be under any duty or
                  responsibility to any Holder to determine whether any Put
                  Event, Restructuring Event, Rating Downgrade or Negative
                  Rating Event (each as defined in the Conditions) has occurred.

17.      TRUSTEE'S LIABILITY

         NOTHING in these presents shall in any case in which the Trustee has
         failed to show the degree of care and diligence required of it as
         trustee having regard to the provisions of these presents conferring on
         it any trusts, powers, authorities or discretions exempt the Trustee
         from or indemnify it against any liability for breach of trust of which
         it may be guilty in relation to its duties under these presents.

18.      TRUSTEE CONTRACTING WITH THE ISSUER AND THE GUARANTOR

         NEITHER the Trustee nor any director or officer or holding company,
         Subsidiary or associated company of a corporation acting as a trustee
         under these presents shall by reason of its or his fiduciary position
         be in any way precluded from:



                                       27
<PAGE>   31

         (i)      entering into or being interested in any contract or financial
                  or other transaction or arrangement with the Issuer or the
                  Guarantor or any person or body corporate associated with the
                  Issuer or the Guarantor (including without limitation any
                  contract, transaction or arrangement of a banking or insurance
                  nature or any contract, transaction or arrangement in relation
                  to the making of loans or the provision of financial
                  facilities or financial advice to, or the purchase, placing or
                  underwriting of or the subscribing or procuring subscriptions
                  for or otherwise acquiring, holding or dealing with, or acting
                  as paying agent in respect of, the Securities or any other
                  bonds, notes stocks, shares, debenture stock, debentures or
                  other securities of, the Issuer or the Guarantor or any person
                  or body corporate associated as aforesaid); or

         (ii)     accepting or holding the trusteeship of any other trust deed
                  constituting or securing any other securities issued by or
                  relating to the Issuer or the Guarantor or any such person or
                  body corporate so associated or any other office of profit
                  under the Issuer or the Guarantor or any such person or body
                  corporate so associated,

         and shall be entitled to exercise and enforce its rights, comply with
         its obligations and perform its duties under or in relation to any such
         contract, transaction or arrangement as is referred to in (i) above or,
         as the case may be, any such trusteeship or office of profit as is
         referred to in (ii) above without regard to the interests of the
         Holders and notwithstanding that the same may be contrary or
         prejudicial to the interests of the Holders and shall not be
         responsible for any Liability occasioned to the Holders thereby and
         shall be entitled to retain and shall not be in any way liable to
         account for any profit made or share of brokerage or commission or
         remuneration or other amount or benefit received thereby or in
         connection therewith.

         Where any holding company, Subsidiary or associated company of the
         Trustee or any director or officer of the Trustee acting other than in
         his capacity as such a director or officer has any information, the
         Trustee shall not thereby be deemed also to have knowledge of such
         information and, unless it shall have actual knowledge of such
         information, shall not be responsible for any loss suffered by Holders
         resulting from the Trustee's failing to take such information into
         account in acting or refraining from acting under or in relation to
         these presents.

19.      WAIVER, AUTHORISATION AND DETERMINATION

(A)      THE Trustee may without the consent or sanction of the Holders and
         without prejudice to its rights in respect of any subsequent breach,
         Event of Default or Potential Event of Default from time to time and at
         any time but only if and in so far as in its opinion the interests of
         the Holders shall not be materially prejudiced thereby waive or
         authorise any breach or proposed breach by the Issuer or the Guarantor
         of any of the covenants or provisions contained in these presents or
         determine that any Event of Default or Potential Event of Default shall
         not be treated as such for the purposes of these presents PROVIDED
         ALWAYS THAT the Trustee shall not exercise any powers conferred on it
         by this Clause in contravention of any express direction given by
         Extraordinary Resolution or by a request under Condition 10 but so that
         no such direction or request shall affect any waiver, authorisation or
         determination previously given or made. Any such waiver, authorisation
         or determination may be given or made on such terms and subject to such
         conditions (if any) as the Trustee may determine, shall be binding on
         the Holders and the Couponholders and, if, but only if, the Trustee
         shall 




                                       28
<PAGE>   32

         so require, shall be notified by the Issuer to the Holders in
         accordance with Condition 14 as soon as practicable thereafter.

         MODIFICATION

(B)      The Trustee may without the consent or sanction of the Holders or
         Couponholders at any time and from time to time concur with the Issuer
         and the Guarantor in making any modification (i) to these presents
         which in the opinion of the Trustee it may be proper to make PROVIDED
         THAT the Trustee is of the opinion that such modification will not be
         materially prejudicial to the interests of the Holders or (ii) to these
         presents if in the opinion of the Trustee such modification is of a
         formal, minor or technical nature or to correct a manifest error. Any
         such modification may be made on such terms and subject to such
         conditions (if any) as the Trustee may determine, shall be binding upon
         the Holders and the Couponholders and, unless the Trustee agrees
         otherwise, shall be notified by the Issuer to the Holders in accordance
         with Condition 14 as soon as practicable thereafter.

         BREACH

(C)      Any breach of or failure to comply with any such terms and conditions
         as are referred to in sub-clauses (A) and (B) of this Clause shall
         constitute a default by the Issuer or the Guarantor (as the case may
         be) in the performance or observance of a covenant or provision binding
         on it under or pursuant to these presents.

20.      HOLDER OF DEFINITIVE BEARER SECURITY ASSUMED TO BE COUPONHOLDER

(A)      WHEREVER in these presents the Trustee is required or entitled to
         exercise a power, trust, authority or discretion under these presents,
         except as ordered by a court of competent jurisdiction or as required
         by applicable law, the Trustee shall, notwithstanding that it may have
         express notice to the contrary, assume that each Holder is the holder
         of all Coupons appertaining to each Bearer Security in definitive form
         of which he is the holder.

         NO NOTICE TO COUPONHOLDERS

(B)      Neither the Trustee nor the Issuer nor the Guarantor shall be required
         to give any notice to the Couponholders for any purpose under these
         presents and the Couponholders shall be deemed for all purposes to have
         notice of the contents of any notice given to the Holders in accordance
         with Condition 14.

         ENTITLEMENT TO TREAT HOLDER AS ABSOLUTE OWNER

(C)      The Issuer, the Guarantor, the Trustee, the Paying Agents, the
         Registrar and the Transfer Agents may (to the fullest extent permitted
         by applicable laws) deem and treat the holder of any Security or of a
         particular principal amount of the Securities and the holder of any
         Coupon as the absolute owner of such Security, principal amount or
         Coupon, as the case may be, for all purposes (whether or not such
         Security, principal amount or Coupon shall be overdue and
         notwithstanding any notice of ownership thereof or of trust or other
         interest with regard thereto, any notice of loss or theft thereof or
         any writing thereon), and the Issuer, the Guarantor, the Trustee, the
         Paying Agents, the Registrar and the Transfer Agents shall not be
         affected by any notice to the contrary. All payments made to any such
         holder of a Security in definitive form or a Coupon or to the bearer of
         a Global Security shall be valid and, to 



                                       29
<PAGE>   33

         the extent of the sums so paid, effective to satisfy and discharge the
         liability for the moneys payable in respect of such Security, principal
         amount or Coupon, as the case may be.

21.      SUBSTITUTION

(A)      (1)      The Trustee may without the consent of the Holders or
                  Couponholders at any time agree with the Issuer to the
                  substitution in place of the Issuer (or of any previous
                  substitute or substitutes under this Clause) as the principal
                  debtor under these presents of the Guarantor or any other
                  Subsidiary of the Issuer (other than an Excluded Subsidiary)
                  (such substituted company being hereinafter called the "NEW
                  COMPANY") provided that a trust deed is executed or some other
                  form of undertaking is given by the New Company in form and
                  manner satisfactory to the Trustee, agreeing to be bound by
                  the provisions of these presents with any consequential
                  amendments which the Trustee may deem appropriate as fully as
                  if the New Company had been named in these presents as the
                  principal debtor in place of the Issuer (or of any previous
                  substitute or substitutes under this Clause).

         (2)      The following further conditions shall apply to (1) above:

                  (i)      the Issuer, the Guarantor and the New Company shall
                           comply with such other requirements as the Trustee
                           may direct in the interests of the Holders;

                  (ii)     where the New Company is incorporated, domiciled or
                           resident in, or subject generally to the taxing
                           jurisdiction of, a territory other than or in
                           addition to the United Kingdom or any political
                           sub-division or any authority therein or thereof
                           having power to tax, undertakings or covenants shall
                           be given by the New Company in terms corresponding to
                           the provisions of Condition 8 with the substitution
                           for (or, as the case may be, the addition to) the
                           references to the United Kingdom of references to
                           that other or additional territory in which the New
                           Company is incorporated, domiciled or resident or to
                           whose taxing jurisdiction it is subject and (where
                           applicable) Condition 6(b) shall be modified
                           accordingly;

                  (iii)    without prejudice to the rights of reliance of the
                           Trustee under the immediately following paragraph
                           (iv), the Trustee is satisfied that the relevant
                           transaction is not materially prejudicial to the
                           interests of the Holders; and

                  (iv)     if two Directors of the New Company (or other
                           officers acceptable to the Trustee) shall certify
                           that the New Company is solvent at the time at which
                           the relevant transaction is proposed to be effected
                           (which certificate the Trustee may rely upon
                           absolutely) the Trustee shall not be under any duty
                           to have regard to the financial condition, profits or
                           prospects of the New Company or to compare the same
                           with those of the Issuer or the previous substitute
                           under this Clause as applicable.

(B)      Any such trust deed or undertaking shall, if so expressed, operate to
         release the Issuer or the previous substitute as aforesaid from all of
         its obligations as principal debtor under these presents. Not later
         than 14 days after the execution of such documents and compliance with
         such requirements, the New Company shall give notice thereof in a form
         previously 




                                       30
<PAGE>   34

         approved by the Trustee to the Holders in the manner provided in
         Condition 14. Upon the execution of such documents and compliance with
         such requirements, the New Company shall be deemed to be named in these
         presents as the principal debtor in place of the Issuer (or in place of
         the previous substitute under this Clause) under these presents and
         these presents shall be deemed to be modified in such manner as shall
         be necessary to give effect to the above provisions and, without
         limitation, references in these presents to the Issuer shall, unless
         the context otherwise requires, be deemed to be or include references
         to the New Company.

22.      CURRENCY INDEMNITY

         EACH of the Issuer and the Guarantor shall severally indemnify the
         Trustee, every Appointee, the Holders and the Couponholders and keep
         them indemnified against:

         (a)      any Liability incurred by any of them arising from the
                  non-payment by the Issuer or the Guarantor of any amount due
                  to the Trustee or the Holders or Couponholders under these
                  presents by reason of any variation in the rates of exchange
                  between those used for the purposes of calculating the amount
                  due under a judgment or order in respect thereof and those
                  prevailing at the date of actual payment by the Issuer or the
                  Guarantor; and

         (b)      any deficiency arising or resulting from any variation in
                  rates of exchange between (i) the date as of which the local
                  currency equivalent of the amounts due or contingently due
                  under these presents (other than this Clause) is calculated
                  for the purposes of any bankruptcy, insolvency or liquidation
                  of the Issuer or the Guarantor and (ii) the final date for
                  ascertaining the amount of claims in such bankruptcy,
                  insolvency or liquidation. The amount of such deficiency shall
                  be deemed not to be reduced by any variation in rates of
                  exchange occurring between the said final date and the date of
                  any distribution of assets in connection with any such
                  bankruptcy, insolvency or liquidation.

         The above indemnities shall constitute obligations of the Issuer and
         the Guarantor separate and independent from their obligations under the
         other provisions of these presents and shall apply irrespective of any
         indulgence granted by the Trustee or the Holders or the Couponholders
         from time to time and shall continue in full force and effect
         notwithstanding the judgment or filing of any proof or proofs in any
         bankruptcy, insolvency or liquidation of the Issuer or the Guarantor
         for a liquidated sum or sums in respect of amounts due under these
         presents (other than this Clause). Any such deficiency as aforesaid
         shall be deemed to constitute a loss suffered by the Holders and
         Couponholders and no proof or evidence of any actual loss shall be
         required by the Issuer or the Guarantor or their liquidator or
         liquidators.

23.      NEW TRUSTEE

(A)      THE power to appoint a new trustee of these presents shall be vested in
         the Issuer but no person shall be appointed who shall not previously
         have been approved by an Extraordinary Resolution. One or more persons
         may hold office as trustee or trustees of these presents but such
         trustee or trustees shall be or include a Trust Corporation. Whenever
         there shall be more than two trustees of these presents the majority of
         such trustees shall be competent to execute and exercise all the
         duties, powers, trusts, authorities and discretions vested in the
         Trustee by these presents provided that a Trust Corporation shall be
         included in such majority. Any appointment of a new trustee of these
         presents shall as soon as practicable thereafter be 




                                       31
<PAGE>   35

         notified by the Issuer to the Principal Paying Agent, the Registrar,
         the Transfer Agents and the Holders.

         SEPARATE AND CO-TRUSTEES

(B)      Notwithstanding the provisions of sub-clause (A) above, the Trustee
         may, upon giving prior notice to the Issuer and the Guarantor (but
         without the consent of the Issuer, the Guarantor, the Holders or the
         Couponholders), appoint any person established or resident in any
         jurisdiction (whether a Trust Corporation or not) to act either as a
         separate trustee or as a co-trustee jointly with the Trustee:

         (i)      if the Trustee considers such appointment to be in the
                  interests of the Holders;

         (ii)     for the purposes of conforming to any legal requirements,
                  restrictions or conditions in any jurisdiction in which any
                  particular act or acts is or are to be performed; or

         (iii)    for the purposes of obtaining a judgment in any jurisdiction
                  or the enforcement in any jurisdiction of either a judgment
                  already obtained or any of the provisions of these presents
                  against the Issuer and/or the Guarantor.

         Each of the Issuer and the Guarantor irrevocably appoints the Trustee
         to be its attorney in its name and on its behalf to execute any such
         instrument of appointment. Such a person shall (subject always to the
         provisions of these presents) have such trusts, powers, authorities and
         discretions (not exceeding those conferred on the Trustee by these
         presents) and such duties and obligations as shall be conferred or
         imposed by the instrument of appointment. The Trustee shall have power
         in like manner to remove any such person. Such reasonable remuneration
         as the Trustee may pay to any such person, together with any
         attributable Liabilities incurred by it in performing its function as
         such separate trustee or co-trustee, shall for the purposes of these
         presents be treated as Liabilities incurred by the Trustee.

24.      TRUSTEE'S RETIREMENT AND REMOVAL

         A trustee of these presents may retire at any time on giving not less
         than three months' prior written notice to the Issuer and the Guarantor
         without giving any reason and without being responsible for any
         Liabilities incurred by reason of such retirement. The Holders may by
         Extraordinary Resolution remove any trustee or trustees for the time
         being of these presents. The Issuer, failing whom the Guarantor,
         undertakes that in the event of the only trustee of these presents
         which is a Trust Corporation (for the avoidance of doubt, disregarding
         for this purpose any separate or co-trustee appointed under Clause
         23(B)) giving notice under this Clause or being removed by
         Extraordinary Resolution it will use its best endeavours to procure
         that a new trustee of these presents being a Trust Corporation is
         appointed as soon as reasonably practicable thereafter. The retirement
         or removal of any such trustee shall not become effective until a
         successor trustee being a Trust Corporation is appointed and, if in
         such circumstances, no such appointment has become effective within two
         months of the date of such notice or Extraordinary Resolution, the
         Trustee shall be entitled to appoint a Trust Corporation as trustee of
         these presents, but no such appointment shall take effect unless
         previously approved by an Extraordinary Resolution.

25.      TRUSTEE'S POWERS TO BE ADDITIONAL

         THE powers conferred upon the Trustee by these presents shall be in
         addition to any powers which may from time to time be vested in the
         Trustee by the general law or as a holder of any of the Securities or
         Coupons.

2.       EXCHANGE FOR PERMANENT GLOBAL BOND AND PURCHASES

         This temporary Global Bond is exchangeable in whole or in part upon the
         request of the bearer for a further global bond in respect of up to
         L.300,000,000 aggregate principal amount of the Bonds (the

         Bond submitted for exchange PROVIDED THAT if definitive Bonds (together
         with the Coupons appertaining thereto) have already been issued in
         exchange for all the Bonds represented for the time being by the
         Permanent Global Bond, then this temporary Global Bond may thereafter
         be exchanged only for definitive Bonds (together with the Coupons
         appertaining thereto) and in such circumstances references herein to
         the Permanent Global Bond shall be construed accordingly and PROVIDED
         FURTHER THAT the Permanent Global Bond shall be issued and delivered
         (or, as the case may be, endorsed) only if and to the extent that there
         shall have been presented to the Issuer a certificate from Morgan
         Guaranty Trust Company of New York, Brussels office, as operator of the
         Euroclear System ("EUROCLEAR") or from Cedelbank substantially in the

         Bond, the Permanent Global Bond and the Trust Deed, otherwise be
         entitled to receive a definitive Bond or definitive Bonds shall not be
         entitled to require the exchange of an appropriate part of this
         temporary Global Bond for a like part of the Permanent Global Bond

         like part of the Permanent Global Bond or (ii) the purchase for
         cancellation by or on behalf of the Issuer, the Guarantor or any other
         Subsidiary of the Guarantor and cancellation of a part of this
         temporary Global Bond in accordance with the Conditions, the portion of
         the principal amount hereof so exchanged or so purchased and cancelled
         shall be endorsed by or on behalf of the Principal Paying Agent on
         behalf of the Issuer on Part II of the Schedule hereto, whereupon the
         principal amount hereof shall be reduced for all purposes by the amount
         so exchanged or so purchased and cancelled and, in each case, endorsed.

3.       PAYMENTS

         Until the entire principal amount of this temporary Global Bond has

         Global Bond for exchange, issue and 



                                       36
<PAGE>   40

         delivery (or, as the case may be, endorsement) of the Permanent Global
         Bond is improperly withheld or refused and such withholding or refusal
         is continuing at the relevant payment date) be entitled (i) to receive
         any payment of interest on this temporary Global Bond except (subject
         to (ii) below) upon certification as hereinafter provided or (ii) on

         Global Bond. Upon any payment of principal or interest on this
         temporary Global Bond the amount so paid shall be endorsed by or on
         behalf of the Principal Paying Agent on behalf of the Issuer on Part I
         of the Schedule hereto.

         presentation to the Issuer of a certificate from Euroclear or from
         Cedelbank substantially in the form of the certificate attached as

         not be entitled to require such payment unless and until he shall have
         delivered or caused to be delivered to Euroclear or Cedelbank a
         certificate substantially in the form of the certificate attached as

         offices of Euroclear in Brussels and Cedelbank in Luxembourg and the
         specified office of each of the Paying Agents).

         Upon any payment of principal and endorsement of such payment on Part I
         of the Schedule hereto, the principal amount of this temporary Global
         Bond shall be reduced for all purposes by the principal amount so paid
         and endorsed.

         All payments of any amounts payable and paid to the bearer of this
         temporary Global Bond shall be valid and, to the extent of the sums so
         paid, effectual to satisfy and discharge the liability for the moneys
         payable hereon, on the Permanent Global Bond and on the relevant
         definitive Bonds and Coupons.

4.       MEETINGS

         The holder hereof shall, at any meeting of Bondholders, be treated as

         accountholders with entitlements to the Permanent Global Bond or this
         temporary Global Bond (as the case may be) and may consider such

         the relevant notice to Euroclear and/or Cedelbank (as the case may be)

         otherwise) of the United Kingdom which would not be suffered were the
         Bonds in definitive form and a certificate to such effect signed by two
         Directors of the Issuer is delivered to the Trustee. Thereupon (in the
         case of (i) above) the holder of this permanent Global Bond (acting on
         the instructions of a person having a beneficial interest in this
         permanent Global Bond) or the Trustee may give notice to the Issuer,
         and (in the case of (ii) above) the Issuer may give notice to the
         Trustee and the Bondholders, of its intention to exchange this
         permanent Global Bond for definitive Bonds on or after the Exchange
         Date (as defined below).

         On or after the Exchange Date the holder of this permanent Global Bond
         may surrender this permanent Global Bond to or to the order of the
         Principal Paying Agent. In exchange for the whole of this permanent
         Global Bond the Issuer will deliver, or procure the delivery of, an
         equal aggregate principal amount of duly executed and authenticated
         definitive Bonds in bearer form, serially numbered, in the
         denominations of L.1,000, L.10,000 and L.100,000 each with interest
         coupons ("COUPONS") attached on issue in respect of interest which has
         not already been paid on this permanent Global Bond.

         "EXCHANGE DATE" means a day specified in the notice requiring exchange
         falling not less than 60 days after that on which the notice requiring
         exchange is given and on which banks are open for business in the city
         in which the specified office of the Principal Paying Agent is located
         and in the cities in which the relevant clearing systems are located.

         Upon (i) any exchange of a part of the Temporary Global Bond for a part
         of this permanent Global Bond or (ii) the purchase for cancellation by
         or on behalf of the Issuer, the Guarantor or any other Subsidiary of
         the Guarantor and cancellation of a part of this permanent Global Bond
         in accordance with the Conditions, the portion of the principal amount
         hereof so exchanged or so purchased and cancelled shall be endorsed by
         or on behalf of the Principal Paying Agent on behalf of the Issuer on
         Part II of the Schedule hereto, whereupon the principal amount hereof
         shall be increased or, as the case may be, reduced for all purposes by
         the amount so exchanged or so purchased and cancelled and endorsed.
         Upon the exchange of the whole of this permanent Global Bond for
         definitive Bonds this permanent Global Bond shall be surrendered to or
         to the order of the Principal Paying Agent and cancelled and, if the
         holder of this permanent Global Bond requests, returned to it together
         with any relevant definitive Bonds.

3.       MEETINGS

         The holder hereof shall, at any meeting of Bondholders, be treated as
         having one vote in respect of each L.1 principal amount of Bonds
         for which this permanent Global Bond may be exchanged.

4.       TRUSTEE'S POWERS

         In considering the interests of Bondholders in circumstances where all
         of the Bonds are represented by one or both of the Temporary Global
         Bond and this permanent Global Bond and such Global Bond(s) is/are held
         on behalf of Euroclear and/or Cedelbank, the Trustee may have regard to
         any information provided to it by such clearing system or its operator
         as to the identity (either individually or by way of category) of its
         accountholders with entitlements to the Temporary Global Bond or this
         permanent Global Bond (as the case may be) and may consider such
         interests as if such accountholders were the holder(s) of the Temporary
         Global Bond or this permanent Global Bond (as the case may be).

5.       PAYMENTS

         Until the entire principal amount of this permanent Global Bond has
         been extinguished, this permanent Global Bond shall (subject as
         hereinafter and in the Trust Deed provided) in all respects be entitled
         to the same benefits as the definitive Bonds and shall be entitled to
         the benefit of and be bound by the Trust Deed. Payments of principal
         and interest in respect of Bonds represented by this permanent Global
         Bond will be made against presentation for endorsement and, if no
         further payment falls to be made in respect of the Bonds, surrender of
         this permanent Global Bond to the order of the Principal Paying Agent
         or such other Paying Agent as shall have been notified to the
         Bondholders for such purposes. Upon any payment of principal or
         interest on this permanent Global Bond the amount so paid shall be
         endorsed by or on behalf of the Principal Paying Agent on behalf of the
         Issuer on Part I of the Schedule hereto.

         Upon any payment of principal and endorsement of such payment on Part I
         of the Schedule hereto, the principal amount of this permanent Global
         Bond shall be reduced for all purposes by the principal amount so paid
         and endorsed.

         All payments of any amounts payable and paid to the bearer of this
         permanent Global Bond shall be valid and, to the extent of the sums so
         paid, effectual to satisfy and discharge the liability for the moneys
         payable hereon and on the relevant definitive Bonds and Coupons.

6.       NOTICES

         permanent Global Bond will be calculated on such basis as the Trustee
         may agree. If, after such redenomination, definitive Bonds are required
         to be issued, they shall be issued at the expense of the Issuer and in
         such denominations as the Trustee and the Principal Paying Agent may
         determine and as shall be notified to the Bondholders in accordance
         with Condition 14.

12.      AUTHENTICATION

                               THE THIRD SCHEDULE

                 REGISTER AND TRANSFER OF REGISTERED SECURITIES

1.       The Issuer shall at all times ensure that the Registrar maintains in
         London, or at such other place in the United Kingdom as the Trustee may
         agree, a register showing the amount of the Registered Securities from
         time to time outstanding and the dates of issue and all subsequent
         transfers and changes of ownership thereof and the names and addresses
         of the holders of the Registered Securities. The Trustee and the
         holders of the Registered Securities or any of them and any person
         authorised by it or any of them may at all reasonable times during
         office hours inspect the register and take copies of or extracts from
         it. The register may be closed by the Issuer for such periods at such
         times (not exceeding in total 30 days in any one year) as it may think
         fit.

2.       Each Registered Security shall have an identifying serial number which
         shall be entered on the register.

3.       The Registered Securities are transferable by execution of the form of
         transfer endorsed thereon under the hand of the transferor or, where
         the transferor is a corporation, under its common seal or under the
         hand of two of its officers duly authorised in writing.

4.       The Registered Securities to be transferred must be delivered for
         registration to the specified office of the Registrar or any Transfer
         Agent with the form of transfer endorsed thereon duly completed and
         executed and must be accompanied by such documents, evidence and
         information as may be required pursuant to the Conditions and such
         other evidence as the Issuer may reasonably require to prove the title
         of the transferor or his right to transfer the Registered Securities
         and, if the form of transfer is executed by some other person on his
         behalf or in the case of the execution of a form of transfer on behalf
         of a corporation by its officers, the authority of that person or those
         persons to do so.

5.       The executors or administrators of a deceased holder of Registered
         Securities (not being one of several joint holders) and in the case of
         the death of one or more of several joint holders the survivor or
         survivors of such joint holders shall be the only person or persons
         recognised by the Issuer as having any title to such Registered
         Securities.

6.       Any person becoming entitled to Registered Securities in consequence of
         the death or bankruptcy of the holder of such Registered Securities may
         upon producing such evidence that he holds the position in respect of
         which he proposes to act under this paragraph or of his title as the
         Issuer shall require be registered himself as the holder of such
         Registered Securities or, subject to the preceding paragraphs as to
         transfer, may transfer such Registered Securities. The Issuer shall be
         at liberty to retain any amount payable upon the Registered Securities
         to which any person is so entitled until such person shall be
         registered as aforesaid or shall duly transfer the Registered
         Securities.

7.       Unless otherwise requested by him, the holder of Registered Securities
         of any series shall be entitled to receive only one Registered Security
         in respect of his entire holding of such series.

8.       The joint holders of Registered Securities of any series shall be
         entitled to one Registered Security only in respect of their joint
         holding of such series which shall, except where they 



                                       59
<PAGE>   63

         otherwise direct, be delivered to the joint holder whose name appears
         first in the register of the holders of Registered Securities in
         respect of such joint holding.

9.       Where a holder of Registered Securities has transferred part only of
         his holding of any series there shall be delivered to him without
         charge a Registered Security in respect of the balance of such holding.

10.      The Issuer shall make no charge to the Holders for the registration of
         any holding of Registered Securities or any transfer thereof or for the
         issue thereof or for the delivery thereof at the specified office of
         the Registrar or of any Transfer Agent or by post to the address
         specified by the Holder. If any Holder entitled to receive a Registered
         Security wishes to have the same delivered to him otherwise than at the
         specified office of the Registrar or of any Transfer Agent, such
         delivery shall be made, upon his written request to the Registrar or
         such Transfer Agent, at his risk and (except where sent by post to the
         address specified by the Holder) at his expense.

11.      The holder of a Registered Security may (to the fullest extent
         permitted by applicable laws) be treated at all times, by all persons
         and for all purposes as the absolute owner of such Registered Security
         notwithstanding any notice any person may have of the right, title,
         interest or claim of any other person thereto. The Issuer, the
         Guarantor and the Trustee shall not be bound to see to the execution of
         any trust to which any Registered Security may be subject and no notice
         of any trust shall be entered on the register. The holder of a
         Registered Security will be recognised by the Issuer and the Guarantor
         as entitled to his Registered Security free from any equity, set-off or
         counterclaim on the part of the Issuer or the Guarantor against the
         original or any intermediate holder of such Registered Security.

                           Paying Agents have their specified offices

                           such meeting is to be held) and such period shall be
                           extended by one period or, to the extent necessary,
                           more periods of 24 hours until there is included as

                  (iv)     "48 HOURS" shall mean a period of 48 hours including
                           all or part of two days upon which banks are open for
                           business both in the place where the relevant meeting
                           is to be held and in each of the places where the
                           Paying Agents have their specified offices
                           (disregarding for this purpose the day upon which
                           such meeting is to be held) and such period shall be
                           extended by one period or, to the extent necessary,
                           more periods of 24 hours until there is included as

                  Paying Agent or require a Paying Agent to issue a block voting
                  instruction in respect of such Bearer Security by depositing
                  such Bearer Security with such Paying Agent or (to the
                  satisfaction of such Paying Agent) by such Bearer Security
                  being held to its order or under its control, in each case not
                  less than 48 hours before the time fixed for the relevant
                  meeting and on the terms set out in sub-paragraph (A)(i)(a) or
                  (A)(ii)(a) above (as the case may be), and (in the case of a
                  block voting instruction) instructing such Paying Agent to the
                  effect set out in sub-paragraph (A)(ii)(b) above. The holder
                  of any voting certificate or the proxies named in any block

                  Agent with which such Bearer Securities have been deposited or
                  the person holding the same to the order or under the control
                  of such Paying Agent shall be deemed for such purposes not to
                  be the holder of those Bearer Securities.

         (C)      (i)      A holder of Registered Securities (whether in
                           definitive form or represented by a Global Security)
                           may, by an instrument in writing in the English
                           language (a "FORM OF PROXY") signed by the holder or,
                           in the case of a corporation, executed under its
                           common seal or signed on its behalf by an attorney or
                           a duly authorised officer of the corporation and
                           delivered to the specified office of the Registrar or
                           any Transfer Agent not less than 48 hours before the
                           time fixed for the relevant meeting, appoint any
                           person (a "PROXY") to act on his or its behalf in
                           connection with any meeting of the Holders and any
                           adjourned such meeting.

                  (ii)     Any holder of Registered Securities which is a
                           corporation may by resolution of its directors or
                           other governing body authorise any person to act as
                           its representative (a "REPRESENTATIVE") in connection
                           with any meeting of the Holders and any adjourned
                           such meeting.

                  (iii)    Any proxy appointed pursuant to sub-paragraph (i)
                           above or representative appointed pursuant to
                           sub-paragraph (ii) above shall so long as such
                           appointment remains in force be deemed, for all
                           purposes in connection with the relevant meeting or
                           adjourned meeting of the Holders, to be the holder of
                           the Registered Securities to which such appointment
                           relates and the holder of the Registered Securities
                           shall be deemed for such purposes not to be the
                           holder.

2.       The Issuer, the Guarantor or the Trustee may at any time and the Issuer
         shall upon a requisition in writing signed by the holders of not less
         than one-tenth in principal amount of the Securities of any series for
         the time being outstanding convene a meeting of the Holders and if the
         Issuer makes default for a period of seven days in convening such a
         meeting the same may be convened by the Trustee or the requisitionists.
         Every such meeting shall be held at such time and place as the Trustee
         may appoint or approve.

3.       At least 21 days' notice (exclusive of the day on which the notice is
         given and the day on which the meeting is to be held) specifying the
         place, day and hour of meeting shall be given to the Holders prior to
         any meeting of the Holders in the manner provided by Condition 14. Such
         notice, which shall be in the English language, shall state generally
         the nature of the business to be transacted at the meeting thereby
         convened but (except for an Extraordinary 




                                       63
<PAGE>   67

         Resolution) it shall not be necessary to specify in such notice the
         terms of any resolution to be proposed. Such notice shall include
         statements, if applicable, to the effect that (i) Bearer Securities
         may, not less than 48 hours before the time fixed for the meeting, be
         deposited with Paying Agents or (to their satisfaction) held to their
         order or under their control for the purpose of obtaining voting
         certificates or appointing proxies and (ii) the holders of Registered
         Securities may appoint proxies by executing and delivering a form of
         proxy in the English language to the specified office of the Registrar
         or any Transfer Agent not less than 48 hours before the time fixed for
         the meeting or, in the case of corporations, may appoint
         representatives by resolution of their directors or other governing
         body. A copy of the notice shall be sent by post to the Trustee (unless
         the meeting is convened by the Trustee), to the Issuer (unless the
         meeting is convened by the Issuer) and to the Guarantor (unless the
         meeting is convened by the Guarantor).

4.       A person (who may but need not be a Holder) nominated in writing by the
         Trustee shall be entitled to take the chair at the relevant meeting or
         adjourned meeting but if no such nomination is made or if at any
         meeting or adjourned meeting the person nominated shall not be present
         within 15 minutes after the time appointed for holding the meeting or
         adjourned meeting the Holders present shall choose one of their number
         to be Chairman, failing which the Issuer may appoint a Chairman. The
         Chairman of an adjourned meeting need not be the same person as was
         Chairman of the meeting from which the adjournment took place.

5.       At any such meeting one or more persons present holding Securities in
         definitive form or voting certificates or being proxies or
         representatives and holding or representing in the aggregate not less
         than one-twentieth of the principal amount of the Securities for the
         time being outstanding shall (except for the purpose of passing an
         Extraordinary Resolution) form a quorum for the transaction of business
         and no business (other than the choosing of a Chairman) shall be
         transacted at any meeting unless the requisite quorum be present at the
         commencement of the relevant business. The quorum at any such meeting
         for passing an Extraordinary Resolution shall (subject as provided
         below) be one or more persons present holding Securities in definitive
         form or voting certificates or being proxies or representatives and
         holding or representing in the aggregate a clear majority in principal
         amount of the Securities for the time being outstanding PROVIDED THAT
         at any meeting the business of which includes any of the following
         matters (each of which shall, subject only to Clause 19(B)(ii), only be
         capable of being effected after having been approved by Extraordinary
         Resolution) namely:

         (i)      reduction or cancellation of the amount payable or, where
                  applicable, modification, except where such modification is in
                  the opinion of the Trustee bound to result in an increase, of
                  the method of calculating the amount payable or modification
                  of the date of payment or, where applicable, of the method of
                  calculating the date of payment in respect of any principal,
                  premium or interest in respect of the Securities;

         (ii)     alteration of the currency in which payments under the
                  Securities and Coupons are to be made;

         (iii)    alteration of the majority required to pass an Extraordinary
                  Resolution;

         (iv)     the sanctioning of any such scheme or proposal as is described
                  in paragraph 18(I) below; and



                                       64
<PAGE>   68

         (v)      alteration of this proviso or the proviso to paragraph 6
                  below;

         the quorum for passing the requisite Extraordinary Resolution shall be
         one or more persons present holding Securities in definitive form or
         voting certificates or being proxies or representatives and holding or
         representing in the aggregate not less than two-thirds of the principal
         amount of the Securities for the time being outstanding.

6.       If within 15 minutes (or such longer period not exceeding 30 minutes as
         the Chairman may decide) after the time appointed for any such meeting
         a quorum is not present for the transaction of any particular business,
         then, subject and without prejudice to the transaction of the business
         (if any) for which a quorum is present, the meeting shall if convened
         upon the requisition of Holders be dissolved. In any other case it
         shall stand adjourned to the same day in the next week (or if such day
         is a public holiday the next succeeding business day) at the same time
         and place (except in the case of a meeting at which an Extraordinary
         Resolution is to be proposed in which case it shall stand adjourned for
         such period, being not less than 13 clear days nor more than 42 clear
         days, and to such place as may be appointed by the Chairman either at
         or subsequent to such meeting and approved by the Trustee). If within
         15 minutes (or such longer period not exceeding 30 minutes as the
         Chairman may decide) after the time appointed for any adjourned meeting
         a quorum is not present for the transaction of any particular business,
         then, subject and without prejudice to the transaction of the business
         (if any) for which a quorum is present, the Chairman may either (with
         the approval of the Trustee) dissolve such meeting or adjourn the same
         for such period, being not less than 13 clear days (but without any
         maximum number of clear days), and to such place as may be appointed by
         the Chairman either at or subsequent to such adjourned meeting and
         approved by the Trustee, and the provisions of this sentence shall
         apply to all further adjourned such meetings. At any adjourned meeting
         one or more persons present holding Securities in definitive form or
         voting certificates or being proxies or representatives (whatever the
         principal amount of the Securities so held or represented by them)
         shall (subject as provided below) form a quorum and shall (subject as
         provided below) have power to pass any Extraordinary Resolution or
         other resolution and to decide upon all matters which could properly
         have been dealt with at the meeting from which the adjournment took
         place had the requisite quorum been present PROVIDED THAT at any
         adjourned meeting the quorum for the transaction of business comprising
         any of the matters specified in the proviso to paragraph 5 above shall
         be one or more persons present holding Securities in definitive form or
         voting certificates or being proxies or representatives and holding or
         representing in the aggregate not less than one-third of the principal
         amount of the Securities for the time being outstanding.

7.       Notice of any adjourned meeting at which an Extraordinary Resolution is
         to be submitted shall be given in the same manner as notice of an
         original meeting but as if 10 were substituted for 21 in paragraph 3
         above and such notice shall state the relevant quorum. Subject as
         aforesaid it shall not be necessary to give any notice of an adjourned
         meeting.

8.       Every question submitted to a meeting shall be decided in the first
         instance by a show of hands and in case of equality of votes the
         Chairman shall both on a show of hands and on a poll have a casting
         vote in addition to the vote or votes (if any) to which he may be
         entitled as a Holder or as a holder of a voting certificate or as a
         proxy or as a representative.

9.       At any meeting unless a poll is (before or on the declaration of the
         result of the show of hands) demanded by the Chairman, the Issuer, the
         Guarantor, the Trustee or any person 



                                       65
<PAGE>   69

         present holding a Security in definitive form or a voting certificate
         or being a proxy or representative (whatever the principal amount of
         the Securities so held or represented by him) a declaration by the
         Chairman that a resolution has been carried or carried by a particular
         majority or lost or not carried by a particular majority shall be
         conclusive evidence of the fact without proof of the number or
         proportion of the votes recorded in favour of or against such
         resolution.

10.      Subject to paragraph 12 below, if at any such meeting a poll is so
         demanded it shall be taken in such manner and subject as hereinafter
         provided either at once or after an adjournment as the Chairman directs
         and the result of such poll shall be deemed to be the resolution of the
         meeting at which the poll was demanded as at the date of the taking of
         the poll. The demand for a poll shall not prevent the continuance of
         the meeting for the transaction of any business other than the motion
         on which the poll has been demanded.

11.      The Chairman may with the consent of (and shall if directed by) any
         such meeting adjourn the same from time to time and from place to place
         but no business shall be transacted at any adjourned meeting except
         business which might lawfully (but for lack of required quorum) have
         been transacted at the meeting from which the adjournment took place.

12.      Any poll demanded at any such meeting on the election of a Chairman or
         on any question of adjournment shall be taken at the meeting without
         adjournment.

13.      The Trustee and its lawyers and any director, officer or employee of a
         corporation being a trustee of these presents and any director or
         officer of the Issuer or the Guarantor and the lawyers of either of
         them and any other person authorised so to do by the Trustee may attend
         and speak at any meeting. Save as aforesaid, but without prejudice to
         the proviso to the definition of "outstanding" in Clause 1, no person
         shall be entitled to attend and speak nor shall any person be entitled
         to vote at any meeting of the Holders or join with others in requesting
         the convening of such a meeting or to exercise the rights conferred on
         the Holders by Conditions 10 and 11 unless he either produces the
         Bearer Security or Bearer Securities in definitive form of which he is
         the holder or a voting certificate or is a proxy or a representative or
         is the holder of a Registered Security or Registered Securities in
         definitive form. No person shall be entitled to vote at any meeting in
         respect of Securities held by, for the benefit of, or on behalf of, the
         Issuer, the Guarantor, any other Subsidiary of the Guarantor, any
         holding company of the Guarantor or any other Subsidiary of such
         holding company. Nothing herein shall prevent any of the proxies named
         in any block voting instruction or form of proxy or any representative
         from being a director, officer or representative of or otherwise
         connected with the Issuer or the Guarantor.

14.      Subject as provided in paragraph 13 hereof at any meeting:

         (A)      on a show of hands every person who is present in person and
                  produces a Bearer Security in definitive form or voting
                  certificate or is a holder of Registered Securities in
                  definitive form or is a proxy or representative shall have one
                  vote; and

         (B)      on a poll every person who is so present shall have one vote
                  in respect of each L.1.00 or such other amount as the
                  Trustee may in its absolute discretion stipulate (or, in the
                  case of meetings of holders of Securities denominated in
                  another currency, such amount in such other currency as the
                  Trustee in its absolute discretion may stipulate) in principal
                  amount of the Securities so produced in definitive form or
                  represented by 




                                       66
<PAGE>   70

                  the voting certificate so produced or in respect of which he
                  is a proxy or representative or in respect of which (being in
                  definitive form) he is the holder.

         Without prejudice to the obligations of the proxies named in any block
         voting instruction or form of proxy any person entitled to more than
         one vote need not use all his votes or cast all the votes to which he
         is entitled in the same way.

15.      The proxies named in any block voting instruction or form of proxy and
         representatives need not be Holders.

16.      Each block voting instruction together (if so requested by the Trustee)
         with proof satisfactory to the Trustee of its due execution on behalf
         of the relevant Paying Agent and each form of proxy shall be deposited
         by the relevant Paying Agent or (as the case may be) by the Registrar
         or the relevant Transfer Agent at such place as the Trustee shall
         approve not less than 24 hours before the time appointed for holding
         the meeting or adjourned meeting at which the proxies named in the
         block voting instruction or form of proxy propose to vote and in
         default the block voting instruction or form of proxy shall not be
         treated as valid unless the Chairman of the meeting decides otherwise
         before such meeting or adjourned meeting proceeds to business. A
         notarially certified copy of each block voting instruction and form of
         proxy shall be deposited with the Trustee before the commencement of
         the meeting or adjourned meeting but the Trustee shall not thereby be
         obliged to investigate or be concerned with the validity of or the
         authority of the proxies named in any such block voting instruction or
         form of proxy.

17.      Any vote given in accordance with the terms of a block voting
         instruction or form of proxy shall be valid notwithstanding the
         previous revocation or amendment of the block voting instruction or
         form of proxy or of any of the Holders' instructions pursuant to which
         it was executed provided that no intimation in writing of such
         revocation or amendment shall have been received from the relevant
         Paying Agent or in the case of a Registered Security from the holder
         thereof by the Issuer at its registered office (or such other place as

         document or in several documents in or substantially in like form each
         signed by or on behalf of one or more of the Holders, shall be as

21.      Minutes of all resolutions and proceedings at every meeting of the
         Holders shall be made and entered in books to be from time to time
         provided for that purpose by the Issuer and any such Minutes as
         aforesaid if purporting to be signed by the Chairman of the meeting at
         which such resolutions were passed or proceedings transacted shall be
         conclusive evidence of the matters therein contained and until the
         contrary is proved every such meeting in respect of the proceedings of
         which Minutes have been made shall be deemed to have been duly held and
         convened and all resolutions passed or proceedings transacted thereat
         to have been duly passed or transacted.

22.      (A)      If and whenever the Issuer shall have issued and have
                  outstanding Securities of more than one series the foregoing
                  provisions of this Schedule shall have effect subject to the
                  following modifications:

                  (i)      a resolution which in the opinion of the Trustee
                           affects the Securities of only one series shall be
                           deemed to have been duly passed if passed at a
                           separate meeting of the holders of the Securities of
                           that series;

                  (ii)     a resolution which in the opinion of the Trustee
                           affects the Securities of more than one series but
                           does not give rise to a conflict of interest between
                           the holders of Securities of any of the series so
                           affected shall be deemed to have been duly passed if
                           passed at a single meeting of the holders of the
                           Securities of all the series so affected;

                  (iii)    a resolution which in the opinion of the Trustee
                           affects the Securities of more than one series and
                           gives or may give rise to a conflict of interest
                           between the holders of the Securities of one series
                           or group of series so affected and the holders of the
                           Securities of another series or group of series so
                           affected shall be deemed to have been duly passed
                           only if passed at separate meetings of the holders of
                           the Securities of each series or group of series so
                           affected; and

                  (iv)     to all such meetings all the preceding provisions of
                           this Schedule shall mutatis mutandis apply as though
                           references therein to Securities, Holders and holders
                           were references to the Securities of the series or
                           group of series in question or to the holders of such
                           Securities, as the case may be.

         (B)      If the Issuer shall have issued and have outstanding
                  Securities which are not denominated in pounds sterling, in
                  the case of any meeting of holders of Securities of more than
                  one currency the principal amount of such Securities shall (i)
                  for the purposes of paragraph 2 above be the equivalent in
                  pounds sterling at the spot rate of a bank nominated by the
                  Trustee for the conversion of the relevant currency or
                  currencies into pounds sterling on the seventh dealing day
                  prior to the day on which the requisition in writing is
                  received by the Issuer and (ii) for the purposes of paragraphs
                  5, 6 and 14 above (whether in respect of the meeting or any
                  adjourned such meeting or any poll resulting therefrom) be the
                  equivalent at such spot rate on the seventh dealing day prior
                  to the day of such meeting. In such circumstances, on any poll
                  each person present shall have one vote for each L.1.00 (or
                  such other pounds sterling amount as the Trustee may in its
                  absolute discretion stipulate) in principal amount of the
                  Securities (converted as above) which he holds or represents.

23.      Subject to all other provisions of these presents the Trustee may
         without the consent of the Issuer, the Guarantor, the Holders or the
         Couponholders prescribe such further regulations regarding the
         requisitioning and/or the holding of meetings of Holders and attendance
         and voting thereat as the Trustee may in its sole discretion think fit.

                       TERMS AND CONDITIONS OF THE BONDS
 
     The following is the text of the Terms and Conditions of the Bonds which
(subject to amendment) will be endorsed on each Bond in definitive form if
issued:
 
     The L300,000,000 5.875 per cent. Guaranteed Bonds due 2009 (the "Bonds",
which expression shall in these Terms and Conditions, unless the context
otherwise requires, include any further bonds issued pursuant to Condition 17
and forming a single series with the Bonds) are constituted by a trust deed (the
"Trust Deed") dated 30th March, 1999 between Wessex Water Services Finance Plc
(the "Issuer"), Wessex Water Services Limited (the "Guarantor") as guarantor and
Midland Bank plc (the "Trustee", which expression shall include all persons for
the time being the trustee or trustees under the Trust Deed) as trustee for the
holders of the Bonds (the "Bondholders"). The issue of the Bonds was authorised
by resolutions of the board of directors the Issuer passed on 17th February,
1999 and 19th March, 1999 and the guarantee of the Bonds was authorised by a
resolution of the board of directors of the Guarantor passed on 17th February,
1999 and by a resolution of a duly authorised committee of the board of
directors of the Guarantor passed on 19th March, 1999. The Bonds are, on issue,
listed on the London Stock Exchange Limited (the "London Stock Exchange"). The
statements in these Terms and Conditions include summaries of, and are subject
to, the detailed provisions of and definitions in the Trust Deed. Copies of the
Trust Deed and of an agency agreement (the "Paying Agency Agreement") dated 30th
March, 1999 between the Issuer, the Guarantor, Midland Bank plc as principal
paying agent (the "Principal Paying Agent", which expression shall include any
successor in such capacity), the other paying agents named therein (together
with the Principal Paying Agent, the "Paying Agents", which expression shall
include any additional or successor paying agents) and the Trustee are available
for inspection during normal business hours by the Bondholders and the holders
of the interest coupons appertaining to the Bonds (the "Couponholders" and the
"Coupons" respectively) at the principal office for the time being of the
Trustee, being at the date of issue of the Bonds at Mariner House, Pepys Street,
London EC3N 4DA, and at the specified office of each of the Paying Agents. The
Bondholders and the Couponholders are entitled to the benefit of, are bound by,
and are deemed to have notice of, all the provisions of the Trust Deed and the
Paying Agency Agreement.
 
     Unless defined elsewhere in these Terms and Conditions, words and
expressions used in these Terms and Conditions shall have the meanings given to
them in Condition 18.
 
1.   FORM, DENOMINATIONS AND TITLE
 
     The Bonds are in bearer form, serially numbered, in the denominations of
L1,000, L10,000 and L100,000 each with Coupons attached on issue. Title to the
Bonds and the Coupons will pass by delivery. Bonds of one denomination may not
be exchanged for Bonds of another denomination.
 
     The Issuer, the Guarantor, any Paying Agent and the Trustee may (to the
fullest extent permitted by applicable laws) deem and treat the holder of any
Bond or Coupon as the absolute owner for all purposes (whether or not the Bond
or Coupon shall be overdue and notwithstanding any notice of ownership, trust or
any interest in it or writing on the Bond or Coupon or any notice of previous
loss or theft of the Bond or Coupon).
 
2.   GUARANTEE AND STATUS
 
   (a)  The Guarantor has unconditionally and irrevocably guaranteed the due
        payment of all sums expressed to be payable by the Issuer under the
        Trust Deed, the Bonds and the Coupons. Its obligations in that respect
        (the "Guarantee") are contained in the Trust Deed.
 
   (b)  The Bonds and the Coupons are direct, unconditional and, subject to the
        provisions of Condition 3, unsecured obligations of the Issuer and,
        subject as aforesaid, rank and will rank pari passu without any
        preference among themselves. The payment obligations of the Issuer under
        the Bonds and the Coupons and of the Guarantor under the Guarantee
        shall, save for such exceptions as may be provided by applicable laws
        and subject to Condition 3, at all times
 

                                       72
<PAGE>   76
 
        rank at least equally with all their respective other outstanding
        unsecured and unsubordinated obligations, present and future.
 
3.   NEGATIVE PLEDGE
 
     So long as any of the Bonds remains outstanding (as defined in the Trust
Deed) each of the Issuer and the Guarantor will ensure that no Relevant
Indebtedness of the Issuer, the Guarantor, any Principal Subsidiary or any other
person and no guarantee by the Issuer, the Guarantor or any Principal Subsidiary
of any Relevant Indebtedness of any person will be secured by a mortgage,
charge, lien, pledge or other security interest (each a "Security Interest")
upon, or with the respect to, any of the present or future business,
undertaking, assets or revenues (including any uncalled capital) of the Issuer,
the Guarantor or any Principal Subsidiary unless, before or at the same time as
the creation of the Security Interest, the Issuer and/or the Guarantor shall
take any and all action necessary to ensure that:
 
    (a) all amounts payable by the Issuer under the Bonds, the Coupons and the
        Trust Deed or, as the case may be, the Guarantor's obligations under the
        Trust Deed are secured equally and rateably with the Relevant
        Indebtedness or guarantee, as the case may be, by the same Security
        Interest, in each case to the satisfaction of the Trustee; or
 
    (b) such other Security Interest or guarantee or other arrangement (whether
        or not including the giving of a Security Interest) is provided in
        respect of all amounts payable by the Issuer under the Bonds, the
        Coupons and the Trust Deed or, as the case may be, the Guarantor's
        obligations under the Trust Deed either (i) as the Trustee shall in its
        absolute discretion deem not materially less beneficial to the interests
        of the Bondholders or (ii) as shall be approved by an Extraordinary
        Resolution (as defined in the Trust Deed) of the Bondholders,
 
save that the Issuer, the Guarantor or any Principal Subsidiary may create or
have outstanding a Security Interest in respect of any Relevant Indebtedness
and/or any guarantees given by the Issuer, the Guarantor or any Principal
Subsidiary in respect of any Relevant Indebtedness of any person (without the
obligation to provide a Security Interest or guarantee or other arrangement in
respect of the Bonds, the Coupons and the Trust Deed as aforesaid) where (1)
such Relevant Indebtedness is of a maximum aggregate amount outstanding at any
time not exceeding the greater of L150,000,000 and 15 per cent. of the Capital
and Reserves or (2) such Security Interest is provided by or in respect of a
company becoming a Subsidiary of the Guarantor after 10th March, 1999 and where
such Security Interest exists at the time that company becomes a Subsidiary of
the Guarantor (provided that such Security Interest was not created in
contemplation of that company becoming a Subsidiary of the Guarantor and the
principal amount secured at the time of that company becoming a Subsidiary of
the Guarantor is not subsequently increased).
 
4.   INTEREST
 
     Each Bond bears interest from (and including) 30th March, 1999 (the
"Closing Date") at the rate of 5.87 per cent. per annum payable annually in
arrear on 30th March in each year (each an "Interest Payment Date"), the first
such payment to be made on 30th March, 2000. All amounts of interest due on each
Bond will be rounded upwards, if necessary, to the nearest penny.
 
     Each Bond will cease to hear interest from its due date for redemption
unless, upon due presentation, payment of the principal in respect of such Bond
is improperly withheld or refused or unless default is otherwise made in respect
of such payment, in which event interest shall continue to accrue as provided in
the Trust Deed.
 
     If interest is required to be calculated for a period of less than one
year, it will be calculated on the basis of a 360 day year consisting of 12
months of 30 days each and, in the case of an incomplete month, the number of
days elapsed.
 

                                       73
<PAGE>   77
 
5.   PAYMENTS
 
     Payments of principal in respect of the Bonds will be made against
presentation and surrender (or, in the case of part payment only, endorsement)
of the Bonds and payments of interest due on an Interest Payment Date will be
made against presentation and surrender (or, in the case of part payment only,
endorsement) of the relevant Coupons, in each case at the specified office of
any of the Paying Agents. Payments of interest due other than on an Interest
Payment Date will be made only upon presentation and surrender of the relevant
Bond as aforesaid.
 
     Payments will be made at the specified office of any Paying Agent, at the
option of the holder, by sterling cheque drawn on, or by transfer to a sterling
account maintained by the payee with, a bank in London subject in all cases to
any applicable fiscal or other laws and regulations, but without prejudice to
the provisions of Condition 8. No commissions or expenses shall be charged to
the Bondholders or the Couponholders in respect of such payments.
 
     Each Bond should be presented for redemption (including exercise of the
Bondholders' option pursuant to Condition 7) together with all relative
unmatured Coupons (being Coupons which would otherwise fall due for payment
after the relevant due date for redemption or, as the case may be, the Put Date
(as defined in Condition 7(c)), failing which amount equal to the aggregate
amount of any missing unmatured Coupons will be deducted from the amount of
principal due for payment (or, in the case of payments not being made in full,
that proportion of the full amount of such missing unmatured Coupons which the
amount so paid bears to the total amount due). Each amount so deducted will be
paid in the manner mentioned above against presentation and surrender (or, in
the case of part payment only, endorsement) of the relative missing Coupon at
any time before the expiry of 10 years after the Relevant Date (as defined in
Condition 8) in respect of the relevant Bond (whether or not such Coupon would
otherwise have become void pursuant to Condition 9) or, if later, five years
after the date on which such Coupon would have become due, but not thereafter.
 
     A holder shall be entitled to present a Bond or Coupon for payment only on
a Presentation Date and shall not be entitled to any further interest or other
payment if a Presentation Date falls after the due date.
 
     The names of the initial Paying Agents and their initial specified offices
are set out at the end of these Terms and Conditions. The Issuer and the
Guarantor reserve the right, subject to the prior written approval of the
Trustee, at any time to vary or terminate the appointment of any Paying Agent
and to appoint additional or other Paying Agents provided that they will at all
times maintain at least two Paying Agents having specified offices in separate
European cities approved by the Trustee, one of which, so long as the Bonds are
listed on the London Stock Exchange, shall be London or such other place as the
London Stock Exchange may approve and one of which shall be in a country outside
the European Community. Notice of any termination or appointment and of any
chances in specified offices will be given to the Bondholders promptly by the
Issuer in accordance with Condition 14.
 
6.   REDEMPTION AND PURCHASE
 
   (a)  Unless previously redeemed or purchased and cancelled as provided below,
        each Bond will be redeemed by the Issuer at its principal amount on 30th
        March, 2009.
 
   (b)  If, as a result of any change in, or amendment to, the laws or
        regulations of the United Kingdom or any political sub-division of, or
        any authority in, or of, the United Kingdom having power to tax, or any
        change in the application or official interpretation of such laws or
        regulations, which change or amendment becomes effective after 24th
        March, 1999, the Issuer (or if the Guarantee were called, the Guarantor)
        has or will become obliged to pay additional amounts as provided or
        referred to in Condition 8 (and such amendment or change has been
        evidenced by the delivery by the Issuer or, as the case may be, the
        Guarantor to the Trustee (who shall, in the absence of manifest error,
        accept such certificate as sufficient evidence thereof) of a certificate
        signed by two directors of the Issuer or, as the case may be, the
        Guarantor on behalf of the Issuer or, as the case may be, the Guarantor
        stating that such
 


                                       74
<PAGE>   78

        amendment or change has occurred (irrespective of whether such amendment
        or change is then effective), describing the facts leading thereto and
        stating that such obligation cannot be avoided by the Issuer or, as the
        case may be, the Guarantor taking reasonable measures available to it,
        the Issuer may at its option, having given not less than 30 nor more
        than 60 days' notice to the Bondholders in accordance with Condition 14
        (which notice shall be irrevocable), redeem all, but not some only, of
        the Bonds at their principal amount together with interest accrued to
        but excluding the date of redemption, provided that no notice of
        redemption shall be given earlier than 90 days before the earliest date
        on which the Issuer or, as the case may be, the Guarantor would be
        required to pay such additional amounts were a payment in respect of the
        Bonds or, as the case may be, the Guarantee then due.
 
        Upon the expiry of any such notice as is referred to above (and subject
        as provided above), the Issuer shall be bound to redeem the Bonds at
        their principal amount together with interest accrued to but excluding
        the date of redemption.
 
   (c)  The Issuer may at its option, having given not less than 30 nor more
        than 90 days' notice to the Bondholders in accordance with Condition 14
        (which notice shall be irrevocable), redeem the Bonds in whole or in
        part (but, if in part, in a principal amount of L5,000,000 or integral
        multiples thereof) at the price which shall be the higher of the
        following:
 
    (i)      their principal amount; and
 
    (ii)     that price (the "Redemption Price"), expressed as a percentage
             rounded to three decimal places (0.0005 being rounded upwards), at
             which the Gross Redemption Yield on the Bonds, if they were to be
             purchased at such price on the second dealing day prior to the
             publication of the notice of redemption, would be equal to the
             Gross Redemption Yield on such dealing day of the 5 3/4 per cent.
             Treasury Stock 2009 or, if such stock is no longer in issue, of
             such other United Kingdom Government Stock as the Trustee, with the
             advice of three leading brokers operating in the gilt-edged market
             and/or gilt-edged market makers, shall determine to be appropriate
             (the "Reference Stock") on the basis of the middle market price of
             the Reference Stock prevailing at or about 3:00 p.m. (London time)
             on such dealing day, as determined by Barclays Bank PLC (or such
             other person(s) as the Trustee may approve). Any reference in these
             Terms and Conditions to principal shall, where applicable, be
             deemed to be a reference to the Redemption Price. The "Gross
             Redemption Yield" on the Bonds and the Reference Stock will be
             expressed as a percentage and will be calculated on the basis
             indicated by the Joint Index and Classification Committee of the
             Institute and Faculty of Actuaries as reported in the Journal of
             the Institute of Actuaries, Vol. 105, Part 1, 1978, pate 18 or on
             such other basis as the Trustee may approve.
 
        together with interest (if any) accrued to but excluding the date of
        redemption.
 
        Notices of redemption will specify the date fixed for redemption, the
        applicable redemption price and, in the case of partial redemption, the
        serial numbers of the Bonds called for redemption, the serial numbers of
        any Bonds previously called for redemption and not presented for payment
        and the aggregate principal amount of the Bonds to remain outstanding
        after redemption. Upon the expiry of any notice of redemption delivered
        in accordance with this Condition 6(c) the Issuer shall be bound to
        redeem the Bonds called for redemption in accordance with this Condition
        6(c). Any partial redemption of the Bonds shall be on the basis of
        selection by drawings (the method of such drawings to be approved by the
        Trustee).
 
   (d)  The Issuer, the Guarantor or any other Subsidiary of the Guarantor may
        at any time purchase Bonds (together with unmatured Coupons appertaining
        thereto) in any manner and at any price. If purchases are made by
        tender, tenders must be available to all Bondholders alike. The Bonds so
        purchased, while held by or on behalf of the Issuer, the Guarantor or
        any other Subsidiary of the Guarantor, shall not entitle the holder to
        vote at any meetings of the Bondholders and shall



                                       75
<PAGE>   79
 
        be deemed not to be outstanding for the purposes of Conditions 7(b), 10,
        11 or 15(a) or otherwise as provided in the Trust Deed.
 
   (e)  All Bonds which are redeemed by the Issuer will forthwith be cancelled
        (together with all relative unmatured Coupons attached to the Bonds or
        surrendered with the Bonds) and may not be reissued or resold. Bonds
        purchased by the Issuer, the Guarantor or any other Subsidiary of the
        Guarantor may be held or reissued or resold or surrendered for
        cancellation, unless purchased pursuant to Condition 7, in which case
        such Bonds (together with all relative unmatured Coupons attached to the
        Bonds or surrendered with the Bonds) will forthwith be cancelled as
        aforesaid.
 
7.   REDEMPTION AT THE OPTION OF BONDHOLDERS
 
   (a)  If, at any time while any of the Bonds remains outstanding:
 
    (i)      the Appointment is terminated except in respect of such part of its
             area as is the subject of an appointment or variation by virtue of
             section 7(4)(b) or (bb) of the Water Industry Act; or
 
    (ii)     the Issuer ceases to be a Subsidiary of the Guarantor; or
 
    (iii)    a Restructuring Event occurs and (subject as provided below):
 
      (A)        within the Restructuring Period, either:
 
       (i)            if at the time such Restructuring Event occurs there are
                      Rated Securities, a Rating Downgrade in respect of such
                      Restructuring Event also occurs; or
 
       (ii)           if at such time there are no Rated Securities, a Negative
                      Rating Event in respect of such Restructuring Event also
                      occurs; and
 
      (B)        an Independent Financial Adviser shall have certified in
                 writing to the Issuer, the Guarantor and the Trustee that such
                 Restructuring Event is, in its opinion, materially prejudicial
                 to the interests of the Bondholders (a "Negative
                 Certification").
 
        then, unless at any time the Issuer shall have given a notice under
        Condition 6(b) or under Condition 6(c) in respect of the Bond, the
        holder of each Bond will, upon the giving of a Put Event Notice (as
        defined below), have the option (the "Put Option") to require the Issuer
        to redeem or, at the option of the Issuer, purchase (or procure the
        purchase of) that Bond on the Put Date (as defined below), at its
        principal amount together with (or, where purchased, together with an
        amount equal to) interest accrued to (but excluding) the Put Date.
 
        If, at any time while any of the Bonds remains outstanding, a
        Restructuring Event occurs and prior to the commencement of or during
        the Restructuring Period an Independent Financial Adviser shall have
        certified in writing to the Trustee that such Restructuring Event will
        not be or is not, in its opinion, materially prejudicial to the
        interests of the Bondholders, the foregoing provisions shall cease to
        have any further effect in relation to such Restructuring Event.
 
        A Restructuring Event shall be deemed not to be materially prejudicial
        to the interests of the Bondholders if, notwithstanding the occurrence
        of a Rating Downgrade or a Negative Rating Event, the rating assigned to
        the Rated Securities by any Rating Agency is subsequently increased to,
        or, as the case may be, there is assigned to the Bonds or other
        unsecured and unsubordinated debt of the Guarantor (or of the Issuer or
        any other Subsidiary of the Guarantor which, in any such case, is
        guaranteed on an unsecured and unsubordinated basis by the Guarantor)
        having an initial maturity of five years or more by any Rating Agency,
        an investment grade rating (BBB-/Baa3 or their respective equivalents
        for the time being) or better prior to any Negative Certification being
        issued.
 


                                       76
<PAGE>   80

        Any certification by an Independent Financial Adviser as aforesaid as to
        whether or not, in its opinion, any Restructuring Event is materially
        prejudicial to the interests of the Bondholders shall, in the absence of
        manifest error, be conclusive and binding on the Trustee, the Issuer,
        the Guarantor and the Bondholders.
 
   (b)  Promptly upon, and in any event within 14 days after, the Issuer or the
        Guarantor becoming aware that a Put Event has occurred, the Issuer, or,
        as the case may be, the Guarantor shall, and at any time upon the
        Trustee becoming similarly so aware the Trustee may, and if so requested
        by the holders of at least one-quarter in principal amount of the Bonds
        then outstanding shall, give notice (a "Put Event Notice") to the
        Bondholders in accordance with Condition 14 specifying the nature of the
        Put Event and the procedure for exercising the Put Option.
 
   (c)  To exercise the Put Option, the holder of a Bond must deliver such Bond
        to the specified office of any Paying Agent, on a day which is a
        Business Day in London and in the place of such specified office falling
        within the period (the "Put Period") of 45 days after that on which a
        Put Event Notice is given, accompanied by a duly completed and signed
        notice of exercise in the form (for the time being current) obtainable
        from any specified office of any Paying Agent (a "Put Notice") and in
        which the holder may specify a bank account complying with the
        requirements of Condition 5 to which payment is to be made under this
        Condition 7. Each Bond should be delivered together with all Coupons
        appertaining thereto maturing after the day (the "Put Date") being the
        fifteenth day after the date of expiry of the Put Period, failing which
        an amount equal to the aggregate amount of any missing unmatured Coupon
        will be deducted from the amount of principal due for payment (or, in
        the case of payment not being made in full, that proportion of the full
        amount of such missing unmatured Coupons which the amount so paid bears
        to the total amount due). Each amount so deducted will be paid in the
        manner provided in Condition 5 against presentation and surrender (or,
        in the case of part payment only, endorsement) of the relevant missing
        Coupon at any time before the expiry of 10 years after the Relevant Date
        in respect of the relevant Bond (whether or not the Coupon would
        otherwise have become void pursuant to Condition 9) or, if later, five
        years after the date on which such Coupon would have become due, but not
        thereafter. The Paying Agent to which such Bond and Put Notice are
        delivered shall issue to the Bondholder concerned a non-transferable
        receipt in respect of the Bond so delivered. Payment in respect of any
        Bond so delivered shall be made, if the holder duly specifies an account
        with a bank in London in the Put Notice to which payment is to be made,
        on the Put Date by transfer to that bank account and, in every other
        case, on or after the Put Date in each cash against presentation and
        surrender or (as the case may be) endorsement of such receipt at any
        specified office of any Paying Agent, subject in any such case as
        provided in Condition 5. A Put Notice, once given, shall be irrevocable.
        For the purposes of these Terms and Conditions and the Trust Deed,
        receipts issued pursuant to this Condition 7 shall be treated as if they
        were Bonds. The Issuer shall redeem or, at the option of the Issuer,
        purchase (or procure the purchase of) the relevant Bond on the
        applicable Put Date unless previously redeemed or purchased.
 
   (d)  A Rating Downgrade or a Negative Rating Event or a non-investment grade
        rating shall be deemed not to have occurred as a result or in respect of
        a Restructuring Event if the Rating Agency making the relevant reduction
        in rating or, where applicable, declining to assign a rating of at least
        investment grade as provided in this Condition 7 does not announce or
        publicly confirm or inform the Trustee in writing at its request that
        the reduction or, where applicable, declining to assign a rating of at
        least investment grade was the result, in whole or in part, of any event
        or circumstance comprised in or arising as a result of the applicable
        Restructuring Event.
 
   (e)  The Trust Deed provides that the Trustee is under no obligation to
        ascertain whether a Restructuring Event, a Negative Rating Event or any
        event which could lead to the occurrence of or could constitute a
        Restructuring Event has occurred and until it shall have actual



                                       77
<PAGE>   81
 
        knowledge or express notice pursuant to the Trust Deed to the contrary
        the Trustee may assume that no Restructuring Event, Negative Rating
        Event or such other event has occurred. The Trust Deed also provides
        that in determining whether or not a Restructuring Event has occurred,
        the Trustee may rely solely on an opinion given in a certificate signed
        by two directors of the Issuer or the Guarantor.
 
8.   TAXATION
 
     All payments in respect of the Bonds and the Coupons or under the Guarantee
shall be made free and clear of, and without withholding or deduction for, or on
account of, any present or future taxes, duties, assessments or governmental
charges of whatever nature ("Taxes") imposed or levied by or on behalf of the
United Kingdom, or any political sub-division of, or any authority in, or of,
the United Kingdom having power to tax, unless the withholding or deduction of
such Taxes is required by law. In that event, the Issuer or, as the case may be,
the Guarantor will pay such additional amounts as may be necessary in order that
the net amounts received by the Bondholders and Couponholders after the
withholding or deduction shall equal the respective amounts which would have
been receivable in respect of the Bonds or, as the case may be, Coupons in the
absence of the withholding or deduction, except that no additional amounts shall
be payable in relation to any payment in respect of any Bond or Coupon:
 
   (a)  to, or to a third party on behalf of, a holder who is liable to such
        Taxes in respect of the Bond or Coupon by reason of his having some
        connection with the United Kingdom other than the more holding of the
        Bond or Coupon; or
 
   (b)  presented for payment in the United Kingdom; or
 
   (c)  presented for payment more than 30 days after the Relevant Date except
        to the extent that a holder would have been entitled to additional
        amounts on presenting the same for payment on the last day of such
        period of 30 days, assuming, whether or not such is in fact the case,
        such last day to be a Presentation Date; or
 
   (d)  to, or to a third party on behalf of, a holder who would not be liable
        or subject to the withholding or deduction by making a declaration of
        beneficial ownership of the Bond or Coupon or of non-residence or other
        similar claim for exemption to the relevant tax authority or paying
        agent or any other relevant person.
 
     As used herein, "Relevant Date" means the date on which the payment first
becomes due but, if the full amount of the money payable has not been received
in London by the Principal Paying Agent or the Trustee on or before the due
date, it means the date on which, the full amount of the money having been so
received, notice to that effect shall have been duly given to the Bondholders by
the Issuer in accordance with Condition 14.
 
     Any reference in these Terms and Conditions to any amounts in respect of
the Bonds shall be deemed also to refer to any additional amounts which may be
payable under this Condition or under any undertakings given in addition to, or
in substitution for, this Condition pursuant to the Trust Deed.
 
9.   PRESCRIPTION
 
     Claims against the Issuer and the Guarantor in respect of principal and
interest shall be prescribed and become void unless the relevant Bond or Coupon
is presented for payment within periods of 10 years (in the case of principal)
and five years (in the case of interest) from the relevant Date in respect
thereof.
 
10. EVENTS OF DEFAULT
 
     The Trustee at its discretion may, and if so requested in writing by the
holders of at least one-quarter in principal amount of the Bonds then
outstanding or if so directed by an Extraordinary Resolution of the Bondholders
shall subject to being indemnified to its satisfaction (but, in the case of the
happening of any of the events mentioned in sub-paragraphs (b), (c), (c), (f),
(g) and (h) below, only if the Trustee shall
 

                                       78
<PAGE>   82
 
have certified in writing to the Issuer that such event is, in its opinion,
materially prejudicial to the interests of the Bondholders), give notice to the
Issuer that the Bonds are, and they shall accordingly thereby forthwith become,
immediately due and repayable at their principal amount together with accrued
interest (as provided in the Trust Deed) if any of the following events (each an
"Event of Default") shall have occurred (unless such Event of Default has been
remedied to the satisfaction of the Trustee):
 
   (a)  if default is made for a period of 15 days or more in the payment of any
        principal of or interest on the Bonds or in the payment of the purchase
        price due in respect of any Bond pursuant to Condition 7; or
 
   (b)  if the Issuer or the Guarantor fails to perform or observe any of its
        other obligations under the Bonds or the Trust Deed and (except where
        the Trustee shall have certified to the Issuer or the Guarantor, as the
        case may be, in writing that it considers such failure to be incapable
        of remedy in which case no such notice or continuation as is hereinafter
        mentioned will be required) such failure continues for the period of 60
        days (or such longer period as the Trustee may in its absolute
        discretion permit) next following the service by the Trustee of notice
        on the Issuer or the Guarantor, as the case may be, specifying such
        failure and requiring the same to be remedied; or
 
   (c)  if (i) any other indebtedness for borrowed money of the Issuer, the
        Guarantor or any Principal Subsidiary becomes due and repayable prior to
        its stated maturity by reason of an event of default howsoever described
        or (ii) any such indebtedness for borrowed money is not paid when due
        (or, as the case may be, within any originally applicable grace period)
        or (iii) the Issuer, the Guarantor or any Principal Subsidiary fails to
        pay when due (or, as the case may be, within any originally applicable
        grace period) any amount payable by it under any present or future
        guarantee for, or indemnity in respect of, any indebtedness for borrowed
        money of any person or (iv) any security given by the Issuer, the
        Guarantor or any Principal Subsidiary for any indebtedness for borrowed
        money of any person or for any guarantee or indemnity of indebtedness
        for borrowed money of any person becomes enforceable by reason of
        default in relation thereto and steps are taken to enforce such
        security, save in any such case where there is a bona fide dispute as to
        whether the relevant indebtedness for borrowed money in respect of which
        any one or more of the events mentioned above in this sub-paragraph (c)
        has or have occurred equals or exceeds L15,000,000 (or its equivalent in
        other currencies (as determined by the Trustee)) or, if greater, 1.5 per
        cent of the Capital and Reserves, and for the purposes of this
        sub-paragraph (c), "indebtedness for borrowed money" shall exclude
        Project Finance Indebtedness; or
 
   (d)  if any order shall be made by any competent court or any resolution
        shall be passed for the winding up or dissolution of the Issuer or the
        Guarantor, save for the purposes of amalgamation, merger, consolidation,
        reorganisation, reconstruction or other similar arrangement on terms
        previously approved in writing by the Trustee or by an Extraordinary
        Resolution of the Bondholders; or
 
   (e)  if (i) any order shall be made by any competent court or any resolution
        shall be passed for the winding up or dissolution of a Principal
        Subsidiary (other than the Issuer), save for the purposes of
        amalgamation, merger, consolidation, reorganisation, reconstruction or
        other similar arrangement (A) not involving or arising out of the
        insolvency of such Principal Subsidiary and under which all the surplus
        assets of such Principal Subsidiary are transferred to the Issuer or the
        Guarantor or any other of their respective Subsidiaries (other than an
        Excluded Subsidiary) or (B) the terms of which have previously been
        approved in writing by the Trustee or by an Extraordinary Resolution of
        the Bondholders or (ii) a petition is presented under section 24 of the
        Water Industry Act (and is not dismissed within 60 days) or a special
        order is made under section 24 or section 25 of the Water Industry Act
        in respect of the Guarantor; or
 
   (f)  if the Issuer, the Guarantor or any Principal Subsidiary shall cease to
        carry on the whole or, in the opinion of the Trustee, substantially the
        whole of its business, save in each case for the



                                       79
<PAGE>   83
 
        purposes of amalgamation, merger, consolidation, reorganisation,
        reconstruction or other similar arrangement (i) in respect of a
        Principal Subsidiary, not involving or arising out of the insolvency of
        such Principal Subsidiary and under which all or, in the opinion of the
        Trustee, substantially all of its assets are transferred to another
        member or members of the Group (other than an Excluded Subsidiary) or to
        a transferee or transferees which is or are, or immediately upon such
        transfer become(s), a Principal Subsidiary or Principal Subsidiaries or
        (ii) in respect of a Principal Subsidiary, under which all or
        substantially all of its assets are transferred to a third party or
        parties (whether associates or not) for full consideration by such
        Principal Subsidiary on an arm's length basis or (iii) in respect of the
        Issuer, the Guarantor or any Principal Subsidiary, the terms of which
        have previously been approved in writing by the Trustee or by an
        Extraordinary Resolution of the Bondholders; or
 
   (g)  if the Issuer, the Guarantor or any Principal Subsidiary shall suspend
        or announce its intention to suspend payment of its debts generally or
        shall be declared or adjudicated by a competent court to be unable, or
        shall admit in writing its inability, to pay its debts generally (within
        the meaning of section 123(1) or (2) of the Insolvency Act 1986) as they
        fall due, or shall be adjudicated or found insolvent by a competent
        court or shall enter into any composition or other similar arrangement
        with its creditors generally under section 1 of the Insolvency Act 1986;
        or
 
   (h)  if a receiver, administrative receiver, administrator or other similar
        official shall be appointed in relation to the Issuer, the Guarantor or

        force and effect.
 
     For the purposes of sub-paragraph (g) above, section 123(1)(a) of the
Insolvency Act 1986 shall have effect as if for "L750" there was substituted
"L250,000". Neither the Issuer, the Guarantor nor any Principal Subsidiary shall
be deemed to be unable to pay its debts for the purposes of sub-paragraph (g)
above if any such demand as mentioned in section 123(1)(a) of the Insolvency Act
1986 is being contested in good faith by the Issuer, the Guarantor or the
relevant Principal Subsidiary with recourse to all appropriate measures and
procedures or if any such demand is satisfied before the expiration of such
period as may be stated in any notice given by the Trustee under this Condition.
 
11. ENFORCEMENT
 
     The Trustee may at any time, at its discretion and without notice, take
such proceedings against the Issuer and/or the Guarantor as it may think fit to
enforce the provisions of the Trust Deed, the Bonds and the Coupons but it shall
not be bound to take any proceedings or any other action in relation to the
Trust Deed, the Bonds or the Coupons unless (a) it shall have been so directed
by an Extraordinary Resolution of the Bondholders or so requested in writing by
the holders of at least one-quarter in principal amount of the Bonds then
outstanding, and (b) it shall have been indemnified to its satisfaction. No
Bondholder or Couponholder shall be entitled to proceed directly against the
Issuer or the Guarantor unless the Trustee, having become bound so to proceed,
fails so to do within a reasonable period and such failure shall be continuing.
 
12. SUBSTITUTION
 
     The Trustee may, without the consent of the Bondholders or Couponholders,
agree with the Issuer to the substitution in place of the Issuer (or of any
previous substitute or substitutes under this Condition) as the principal debtor
under the Bonds, the Coupons and the Trust Deed of the Guarantor or any other
Subsidiary of the Guarantor (other than an Excluded Subsidiary) subject to (a)
the Trustee being



                                       80
<PAGE>   84
 
satisfied that the interests of the Bondholders will not be materially
prejudiced by the substitution and (b) certain other conditions set out in the
Trust Deed being complied with.
 
13. REPLACEMENT OF BONDS AND COUPONS
 
     If any Bond or Coupon be lost, stolen, mutilated, defaced or destroyed, it
may be replaced at the specified office of the Principal Paying Agent subject to
all applicable laws and stock exchange requirements, upon payment by the
claimant of the expenses incurred in connection with the replacement and on such
terms as to evidence and indemnity as the Issuer and the Guarantor may
reasonably require. Mutilated or defaced Bonds or Coupons must be surrendered
before replacements will be issued.
 
14. NOTICES
 
     All notices to the Bondholders will be valid if published in a leading
English language daily newspaper published in London (which is expected to be
the Financial Times) or, if in the opinion of the Trustee such publication shall
not be practicable, in an English language daily newspaper with general
circulation in Europe. Any notice shall be deemed to have been given on the date
of publication or, if so published more than once, on the date of the first
publication. If publication as provided above is not practicable, notice will be
given in such other manner, and shall be deemed to have been given on such date,
as the Trustee may approve.
 
     Couponholders will be deemed for all purposes to have notice of the
contents of any notice given to the Bondholders in accordance with this
Condition.
 
15. MEETINGS OF BONDHOLDERS, MODIFICATION, WAIVER AND AUTHORISATION
 
   (a)  The Trust Deed contains provisions for convening meetings of the
        Bondholders to consider any matter affecting their interests, including

        meeting for passing an Extraordinary Resolution will be one or more
        persons present holding or representing a clear majority in principal
        amount of the Bonds for the time being outstanding, or at any adjourned
        such meeting one or more persons present whatever the principal amount
        of the Bonds held or represented by him or them, except that at any
        meeting, the business of which includes modification of certain of the
        provisions of these Terms and Conditions and certain of the provisions
        of the Trust Deed, the necessary quorum for passing an Extraordinary
        Resolution will be one or more persons present holding or representing
        not less than two-thirds, or at any adjourned such meeting not less than
        one-third, of the principal amount of the Bonds for the time being
        outstanding. An Extraordinary Resolution passed at any meeting of the
        Bondholders will be binding on all Bondholders, whether or not they are
        present at the meeting, and on all Couponholders.
 
   (b)  The Trustee may agree, without the consent of the Bondholders or
        Couponholders, to any modification (subject to certain exceptions) of,
        or to the waiver or authorisation of any breach or proposed breach of,
        any of these Terms and Conditions or any of the provisions of the Trust
        Deed which is not, in the opinion of the Trustee, materially prejudicial
        to the interests of the Bondholders or to any modification which is of a
        formal, minor or technical nature or to correct a manifest error.
 
   (c)  In connection with the exercise by it of any of its trusts, powers,
        authorities and discretions (including, without limitation, any
        modification, waiver, authorisation, determination or substitution), the
        Trustee shall have regard to the interests of the Bondholders as a class
        but shall not have regard to any interests arising from circumstances
        particular to individual Bondholders or Couponholders and, in particular
        but without limitation, shall not have regard to the consequences of any
        such exercise for individual Bondholders and Couponholders resulting
        from their being for any purpose domiciled or resident in, or otherwise
        connected with, or subject to the jurisdiction of, any particular
        territory or any political sub-division thereof and the



                                       81
<PAGE>   85
 
        trustee shall not be entitled to require, nor shall any Bondholder or
        Couponholder be entitled to claim, from the Issuer, the Guarantor, the
        Trustee or any other person, any indemnification or payment in respect
        of any tax consequences of any such exercise upon individual Bondholders
        or Couponholders except to the extent already provided for in Condition
        8 and/or any undertaking given in addition to, or in substitution for,
        Condition 8 pursuant to the Trust Deed.
 
   (d)  Any modification, waiver or authorisation referred to in paragraph (b)
        above and any substitution under Condition 12 shall be binding on the
        Bondholders and the Couponholders and, unless the Trustee agrees
        otherwise, any such modification or substitution shall be notified by
        the Issuer to the Bondholders as soon as practicable thereafter in
        accordance with Condition 14.
 
   (e)  The Trustee may, without the consent of the Bondholders or
        Couponholders, on or after the date (if any) on which the United Kingdom
        becomes one of the countries participating in the third stage of
        European economic and monetary union pursuant to the Treaty establishing
        the European Community as amended by the Treaty on European Union or
        otherwise participates in European economic and monetary union in a
        manner with similar effect to such third stage, agree to such
        modifications to the Bonds, the Coupons and the Trust Deed in order to
        facilitate payment of interest in euro and redemption at the euro
        equivalent of the sterling principal amount of the Bonds and associated
        reconventioning, renominalisation and related matters as may be proposed
        by the Issuer (and confirmed by an independent financial institution
        approved by the Trustee to be in conformity with the then applicable
        market conventions).
 
16. INDEMNIFICATION OF THE TRUSTEE
 
     The Trust Deed contains provisions for the indemnification of the Trustee
and for its relief from responsibility, including provisions relieving it from
taking action unless indemnified to its satisfaction. The Trustee is entitled to
enter into business transactions with the Issuer or the Guarantor and any entity
related to the Issuer or the Guarantor without accounting for any profit. The
Trustee may relay without liability to Bondholders on a report of the Auditors,
whether or not addressed to it and whether or not the Auditors have any
liability to it in respect of the same.
 
17. FURTHER ISSUES
 
     The Issuer is at liberty from time to time without the consent of the
Bondholders or Couponholders to create and issue further bonds or notes either
(a) ranking pari passu in all respects (or in all respects save for the first
payment of interest thereon) and so that the same shall be consolidated and form
a single series with the outstanding bonds or notes of any series (including the
Bonds) constituted by the Trust Deed or any deed supplemental to it or (b) upon
such terms as to ranking, interest, conversion, redemption and otherwise as the
Issuer may determine at the time of the issue. Any further bonds or notes which
are to form a single series with the outstanding bonds or notes of any series
(including the Bonds) constituted by the Trust Deed or any deed supplemental to
it shall, and any other further bonds or notes may (with the consent of the
Trustee), be constituted by a deed supplemental to the Trust Deed. The Trust
Deed contains provisions for convening a single meeting of the Bondholders and
the holders of bonds or notes of other series in certain circumstances where the
Trustee so decides.

                                CREDIT AGREEMENT


         CREDIT AGREEMENT (this "Agreement") dated as of May 1, 1999 between
Enron Corp., an Oregon corporation ("Lender"), and Azurix Corp., a Delaware
corporation ("Borrower"). The parties hereby agree as follows:

         1.    Advances. Subject to the terms and conditions of this Agreement,
Lender will make advances ("Advances"), including Advances for the payment of
interest under this Agreement, from its available funds to Borrower from time to
time during the period from the date of this Agreement up to but not including
the Termination Date, as defined in Section 11, in an aggregate principal amount
up to but not exceeding the sum of One Hundred Eighty Million Dollars
(U.S.$180,000,000) at any one time outstanding. The aggregate principal amount
outstanding is further limited by the provisions in Section 2. Within the limits
of this Agreement, Borrower may borrow, prepay pursuant to Section 5, and
reborrow under this Section 1. The parties hereto agree that any Advances by the
Lender will be made in reliance on the agreements of the Lender and the Borrower
contained herein and on the terms and conditions and in the manner provided
herein.

         2.    Limits on the Principal Amount Outstanding. The principal amount
outstanding under this Agreement will be further limited to no more than:

         a) U.S.$ 60,000,000 at any time during the calendar year 1999.

         b) U.S.$120,000,000 at any time during the calendar year 2000.

         c) U.S.$180,000,000 at any time during the calendar year 2001.

In addition, no additional amounts shall be advanced after, and all principal
and interest outstanding under the Note, all interest thereon and all other
amounts payable under this Agreement shall be due and payable 90 days after, the
first date on which both of the following occur:

         i)    Lender and affiliates of Lender do not individually or
               collectively, directly or indirectly, own or have the power to
               vote at least one-third of the capital stock of Borrower having
               ordinary voting power for the election of directors, and

         ii)   Fewer than one-third of the directors of Borrower are persons who
               are employees, officers or directors of Lender or of any
               affiliate of Lender.

         3.    Interest. Interest shall accrue on a daily basis on the
outstanding and unpaid principal amount of the Advances at a rate per annum
equal to the Fed Funds Rate (as defined below) plus 1.50%. For the purposes of
this Agreement, the "Fed Funds Rate" shall be defined as the rate published in
Federal Reserve Statistical Release H.15 as the Federal funds (effective) rate
for that day. In the event that the Fed Funds Rate is not available for a
particular day, employees of Lender's Treasury group shall use the last
published Fed Funds Rate as the Fed Funds Rate for that day.





<PAGE>   2

            Interest shall be calculated on the basis of a year of 360 days for 
the actual number of days elapsed. Interest shall be paid at the offices of
Lender at 1400 Smith Street, Houston, Texas 77002, or each other addresses that
the Lender may specify by notice to the Borrower, in funds immediately available
to Lender on the first Business Day of each quarter.

         4.    Priority of Indebtedness/Note. The indebtedness of Borrower owing
to Lender resulting from Advances made under the provisions of this Credit
Agreement and the Note shall not be subordinate or subordinated to any other
borrowings made by Borrower. All Advances made by Lender under this Agreement
shall be evidenced by, and repaid with interest in accordance with, a single
promissory note of Borrower in substantially the form annexed hereto as Exhibit
A (the "Note"), with appropriate insertions therein. The Note shall be used to
evidence each borrowing, repayment and reborrowing hereunder. The Note shall (i)
be dated the date of the first Advance evidenced thereby and (ii) be stated to
mature as to principal on the Termination Date. Lender is hereby authorized by
Borrower to endorse on the schedule attached to the Note the amount of each
Advance and of each payment of principal received by Lender on account of the
Advances, which endorsement shall, in the absence of manifest error, be
conclusive as to the outstanding balance of the Advances made by Lender,
provided, however, that the failure to make such notation with respect to any
Advance or payment shall not limit or otherwise affect the obligations of
Borrower under this Agreement or the Note.

         5.    Prepayments. Borrower may prepay the Note in whole or in part on
any Business Day.

         6.    Use of Proceeds. The proceeds of the Advances hereunder shall be
used by Borrower to pay for general, administrative and operating expenses.

         7.    Events of Default. If any of the following events ("Events of
Default") shall occur and be continuing:

               (a) The Borrower shall breach any of the material provisions of
         any written Agreement with Lender, including but not limited to this
         Credit Agreement; or

               (b) The Borrower shall generally not pay its debts as such debts
         become due, or shall admit in writing its inability to pay its debts
         generally, or shall make a general assignment for the benefit of
         creditors; or any proceeding shall be instituted by or against the
         Borrower seeking to adjudicate it as bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,
         protection, relief or composition of it or its debts under any law
         relating to bankruptcy, insolvency or reorganization or relief of
         debtors, or seeking the entry of an order for relief or the appointment
         of a receiver, trustee or other similar official for it or for any
         substantial part of its property and, in the case of any such
         proceeding instituted against it (but not instituted by it), shall
         remain undismissed or unstayed for a period of 60 days; or the Borrower
         shall take any corporate action to authorize any of the actions set
         forth above in this subsection (b); or



                                       2

<PAGE>   3

               (c) Any event or events having a material adverse effect on (i)
         the ability of the Borrower to meet its obligations under this
         Agreement or (ii) the business, operations, assets or financial
         condition of the Borrower.

then, and in any such event, Lender may by notice to the Borrower, declare the
Note, all interest thereon and all other amounts payable under this Agreement to
be forthwith due and payable, whereupon the Note, all such interest and all such
amounts shall become and be forthwith due and payable, without presentment,
demand, protest, notice of intent to accelerate or further notice of any kind,
all of which are hereby expressly waived by the Borrower; provided, however,
that in the event of an actual or deemed entry of an order for relief with
respect to Borrower under the Bankruptcy Code, the Note, all such interest and
all such amounts shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by the Borrower.

         8.    Notices, Etc. All notices and other communications provided for
under this Agreement shall be in writing (including telegraphic communication)
and telecopied, telegraphed, or delivered, if to Lender, at its address at 1400
Smith Street, Houston, Texas 77002, Attention: Senior Vice President, Finance
and Treasurer, telecopy number (713) 646-5930 and if to Borrower, at its address
at 333 Clay Street, Houston, Texas 77002, Attention: Vice Chairman and Chief
Financial Officer, telecopy number (713) 646-6367; or, as to each party, at such
other address as shall be designated by such party in a written notice to the
other party complying as to delivery with the terms of this Section 8.

         9.    No Waiver; Remedies. No failure on the part of Lender to
exercise, and no delay in exercising, any right, power, or remedy under this
Agreement or the Note shall operate as a waiver thereof; nor shall any single or
partial exercise of any right under this Agreement or the Note preclude any
other or further exercise thereof or the exercise of any other right. The
remedies provided in this Agreement or the Note are cumulative and not exclusive
of any remedies provided by law.

         10.   Governing Law. This instrument shall be construed under the laws
of the State of Texas, and the obligation of Borrower to make payments of
interest as provided for herein is expressly limited so that the aggregate
amount of all the interest paid by Borrower on the Note shall never exceed the
highest contract rate allowed by the laws of the State of Texas as construed by
the highest court or courts having jurisdiction thereof (the "Highest Lawful
Rate"); and if, at the time any such payment of interest is due or is paid, the
payment of such sum would make the total interest exceed interest calculated at
the Highest Lawful Rate, the amount so payable by Borrower shall be reduced to
an amount which does not exceed the Highest Lawful Rate; and, similarly, if the
maturity of the Note is accelerated for any reason before the due date stated,
earned interest may never include more than interest calculated at the Highest
Lawful Rate, it being the intention of the parties to conform strictly to the
laws of the State of Texas now in force, and in the event it should be held that
the interest payable under the Note or otherwise is in excess of interest
calculated at the Highest Lawful Rate, the interest payable hereunder (whether
included in the face amount or otherwise) shall be reduced to the Highest Lawful
Rate, and any amount in excess of interest 



                                       3

<PAGE>   4


calculated at the Highest Lawful Rate shall be cancelled automatically and shall
be either refunded (if theretofore paid) or credited to the principal amount due
on the Note.

         11.   Termination Date. The "Termination Date" means December 15, 2001.
This Agreement may be terminated early upon mutual consent of the Lender and
Borrower; provided, however, that the provisions of this Agreement shall survive
as to any Advances maturing after the effective termination date. Upon
cancellation of the last such Advance, this Agreement shall be of no further
force and effect.

         12.   Captions. The captions of the various sections of this Agreement
have been inserted only for the purposes of convenience, and shall not be deemed
in any manner to modify, explain, enlarge or restrict any provisions of this
Agreement.

         13.   Business Day. As used herein, Business Day means any day other
than a Saturday, a Sunday or a state or federal bank holiday in Houston, Texas
or New York, New York.

         14.   Entire Agreement. THIS AGREEMENT AND THE NOTE TOGETHER CONSTITUTE
A WRITTEN LOAN AGREEMENT AND REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN
THE PARTIES.



               IN WITNESS WHEREOF, the parties have caused this Agreement to be 
executed by their respective officers thereunto duly authorized, as of the date
first above written.

             take the necessary action to give effect to the discharge of the
             retiring trustee and the vesting of the Fund in any new trustee or

             assurance policies, retirement, endowment or sinking fund contracts
             or policies, or make other suitable arrangements with any one or
             more Approved Insurers for the provision of the pensions or other
             benefits for which the Rules provide. They may enter into any
             arrangements with any Approved Insurer or with any other
             appropriate insurance society, company or institution to re-insure
             the whole or any part of the risks undertaken and in particular to
             re-insure against any excess of claims that might fall upon the
             Scheme. The Trustees may pay all premiums and other moneys (if any)
             from time to time required for effecting and maintaining any such
             policies or arrangements from the Fund. The Trustees shall be
             entitled to deal with any such policies or contracts by way of
             surrender, exchange, mortgage or otherwise, or to make such other
             arrangements in connection therewith as they shall think fit, and
             no Approved Insurer or other society, company or institution as
             aforesaid shall in any case be concerned to ensure as to the object
             of any such dealing or arrangement.

             to time. They may exercise this power upon any terms and conditions
             and secure the repayment of the amount borrowed and the payment of
             interest on it upon the whole or any part or parts of the Fund and
             apply moneys so borrowed in any manner which the Trustees may in
             their absolute discretion (or in the case of such power being
             exercised by an investment manager which that investment manager
             may subject to the consent of the Trustees) think fit for the
             purposes of the Scheme or the relevant part or parts of it. All
             moneys borrowed or raised in this way shall be treated as moneys
             forming part of the Fund. The Trustees or investment manager may
             from time to time if the Trustees consider it to the advantage of
             the Fund to do so, exercise the power given to them by borrowing or
             raising money in any part of the world for the purpose of making
             additional investments to be held as part of the Fund.

7.06         POWER TO INSURE FUND
             The Trustees may insure or procure the insurance of any assets of
             the Fund as they think appropriate, against such risks and for such
             amounts as the Trustees shall in their absolute discretion
             determine (whether as owners of an interest in such assets or as
             occupier or otherwise) and may apply an appropriate part of the
             Fund, whether income or capital, in effecting and maintaining any
             such insurance. The Trustees shall hold the proceeds of this
             insurance upon the trusts of the Scheme with power to pay or apply
             the proceeds, in whole or in part, in or towards the repair,
             replacement, reinstatement or preservation of the asset insured or
             (as the case may be) in indemnifying the Trustees or the Fund
             against any claim made against the Trustees in relation to it, to
             the intent that the powers hereby conferred shall be exercisable by
             the Trustees as if they were the absolute owner of the Fund
             beneficially. Any exercise of such powers shall be unrestricted by
             law.

7.07         POWER TO EFFECT INDEMNITY INSURANCE
             Subject to section 31 of the 1995 Act, the Trustees may at any time
             effect and maintain professional indemnity insurance or other types
             of insurance which they think appropriate in the course of 
             administering the Scheme or protecting the Fund, and may pay all 
             premiums due in respect of such insurance from the Fund.

7.08         FUND MAY BE HELD IN NAME OF NOMINEE
             In the exercise of their powers the Trustees shall ensure that the
             Fund (or any part or parts thereof as appropriate) is at all times
             held in the name of the Trustees, or of any investment manager that
             they may have appointed, or in the name of any nominee or nominees
             which the Trustees shall direct, or jointly in the names of any of
             these parties.

                         Clause 8.01 exercise their duties and their powers and
                         discretions under the Scheme at meetings to be held at
                         such intervals as they think fit PROVIDED that the
                         proceedings at any such meeting shall not be valid
                         unless either:-

                         (i)         7 days' notice of that meeting shall have
                                     been given to each Trustee who was within
                                     the United Kingdom on the date such notice
                                     was served; or

                         (ii)        each of the Trustees who has not been
                                     served with notice as aforesaid agrees to
                                     accept a shorter period of notice or to
                                     waive the requirement for notice.

             For this purpose notice of a meeting shall be deemed to have been
             sufficiently served if in writing and either delivered by hand or
             sent by telex or by facsimile or by pre-paid first class post to
             the Trustee in question at his last known address. Any notice
             served by post as aforesaid shall be deemed to have been served 72
             hours after the same was posted.

             The quorum for any meeting of the Trustees shall be two of the
             Trustees present in person or by proxy. Each of the Trustees shall
             be entitled to cast one vote on any question which may arise at any
             such meeting. Any of the Trustees who is unable to attend such a
             meeting may in writing appoint another of the Trustees or the
             Secretary

                                       13
<PAGE>   21
             to the Trustees as his proxy and such appointee may exercise in
             addition (if a Trustee) to his own vote the vote of the other
             Trustee whom he represents. At every meeting all questions shall be
             decided by a simple majority of votes cast. If there is an equality
             of votes the question shall be decided on the casting vote of the
             Chairman of the meeting. Decisions taken in accordance with this
             Clause 8.01 shall be binding on all the Trustees.

             (b)         A resolution in writing which is signed by all the
                         Trustees shall be binding although no formal meeting of
                         the Trustees was held. Such a resolution may be
                         contained in one document or in several documents in
                         like form each signed by one or more of the Trustees.

             (c)         The Chairman from time to time of the Trustees shall be
                         nominated by the Principal Employer and if such
                         Chairman is not present at any meeting he shall
                         nominate which Trustee shall take the chair at the
                         meeting.

             (d)         The Trustees shall appoint a Secretary who may also be
                         one of the Trustees to assist them in the performance
                         of their duties and the exercise of their powers and
                         discretions. The Secretary shall keep minutes of the
                         meetings and decisions of the Trustees and shall
                         furnish copies thereof to all the Trustees. The
                         Secretary shall also advise the Trustees in relation to
                         the exercise of their duties, powers and discretions in
                         such terms as to ensure so far as possible that their
                         decisions are consistent in similar sets of
                         circumstances although such advice and prior decisions
                         of the Trustees shall not be binding upon them.

             (e)         Save as aforesaid the Trustees shall make their own
                         regulations for the conduct of their business and
                         meetings.

             (f)         No decision of or exercise of a duty, power or
                         discretion by the Trustees or any of them, or by any
                         delegate of the Trustees or by the Secretary shall be
                         invalidated or questioned on the ground that any
                         trustee for the time being of the Scheme or other
                         person aforesaid had a direct or other personal

                         interest in the manner or result of such decision or of

             acting.

             The Trustees shall in accordance with the 1995 Act and the

             in or about the execution and carrying out of the trusts of 
             the Scheme.

             The Trustees may at any time decide that an actuarial valuation of
             the whole or one or more parts of the Scheme shall be conducted by
             the Actuary at a time when no such valuation would otherwise be
             mandatory. The Principal Employer may similarly decide that a

             they or he knew to be a breach of trust and which they or he
             knowingly and wilfully committed or omitted as the case may be.

             demands in respect of any matter or thing made, done or omitted in
             any way relating to the Scheme, unless the same shall be
             attributable to the fraud or wilful default of the Trustee who is
             sought to be made liable. This indemnity shall not extend to a
             claim for value added tax made against a corporate trustee.

11.03        LEGAL PROCEEDINGS
             The Trustees shall not be under any liability to take, institute,

             person made in the mistaken belief that the person was entitled to
             it. A receipt issued to the Trustees by that person shall discharge
             their obligations under the Scheme.

             (i)         This paragraph of Rule 5.03 applies if a Member is on
                         leave of absence from Service because of ill-health or
                         because he has been seconded to a United Kingdom
                         government department or is engaged on similar work of
                         national importance, and is receiving no Pensionable
                         Salary or a reduced rate of Pensionable Salary. Where
                         contributions to the Basic Scheme are being paid by the
                         Member, the Employer shall continue to pay Employer's
                         contributions under Rule 10.00.

             OVERSEAS SERVICE
             (ii)        This paragraph of Rule 5.03 applies if a Member is on
                         leave of absence from Service with the Employer's

                         shall continue to pay Employer's contributions under
                         Rule 10.00 and the provisions of the Basic Scheme


                                       24

                         mutatis mutandis to the Scheme.

             MEMBER ON OVERSEAS SERVICE
             (iii)       This paragraph of Rule 5.03 applies if a Member is on
                         Overseas Service. Such a Member shall remain an Active
                         Member so long as Revenue Approval is not prejudiced as
                         a result. Contributions shall be paid in respect of him
                         and benefits calculated on the basis of the amount
                         certified by the Principal Employer as his Pensionable
                         Salary.

             PERIOD OF ABSENCE ONLY PENSIONABLE IF CONTRIBUTIONS PAID
             (iv)        If contributions to the Basic Scheme are maintained by
                         the Member or paid on his behalf by the Employer during
                         periods of leave of absence for the reasons specified
                         in Rules 5.03(i), (ii) or (iii), the Member will
                         continue to be an Active Member and those periods will
                         form part of his Pensionable Service. No other absences
                         from Service will count as Pensionable Service although
                         the periods of Pensionable Service before and after the
                         break will be treated as continuous subject always to
                         compliance with the provisions of Appendix C.

5.04         CESSATION OF ACTIVE MEMBERSHIP WHILE REMAINING IN SERVICE
             (i)         A Member who ceases to work full-time while remaining
                         in Service shall thereupon cease to be an Active
                         Member.

             LEAVING THE SCHEME VOLUNTARILY
             (ii)        A Member may at any time elect to cease Active
                         Membership on giving the Trustees at least 30 days'
                         notice. His Active Membership shall cease on the first
                         day of the pay period following the expiry of the
                         notice period, and his benefits under the Scheme shall
                         be calculated as at that date and dealt with under Rule
                         15.00 (Benefits on ceasing to be an Active Member).
                         However, where the Member gives notice under Rule 5.01,
                         he shall be treated as never having become an Active
                         Member.

             MEMBER ON OVERSEAS SERVICE
             (iii)       Where a Member on Overseas Service is required to cease
                         being an Active Member, either in order that Revenue
                         Approval will not be prejudiced or because the period
                         that the Board of Inland Revenue permitted him to
                         remain an Active Member has expired his benefits shall
                         be calculated as at that date and dealt with under Rule
                         15.00 (Benefits on ceasing to be an Active Member).
                         Where he returns to Active Membership after his
                         Overseas Service ends, the Member's previous period of
                         Pensionable Service shall be reinstated in place of the
                         preserved Top-Up Pension to which the Member would
                         otherwise be entitled.

5.05         RESUMPTION OF ACTIVE MEMBERSHIP
             If a Member who remains in Service elects to withdraw from Active
             Membership under Rule 5.04(ii), he will be permitted to resume
             Active Membership only if the Principal Employer so determines. In
             that event the Principal Employer may at its discretion allow the
             Member's previous period of Pensionable Service to be reinstated as
             an alternative to the preserved Top-Up Pension to which the Member
             would otherwise be entitled.

             Trustees the initial rate at which he will pay Voluntary
             Contributions, being not less than 0.5% of the Member's
             Remuneration (as defined in Appendix C) in that tax year or such
             greater amount as may from time to time be prescribed by law.

8.02         Voluntary Contributions may be discontinued, reduced or increased
             on 12 months' notice to the Trustees or such shorter period as they
             shall at their discretion allow.

             Contributions:-

             (i)         No further contributions shall be payable after
                         cessation of Active Membership;

             (ii)        Voluntary Contributions shall not be of such an amount
                         that:-

                         (a)         the total of the Member's Voluntary
                                     Contributions and his contributions to the
                                     Basic Scheme would in any Scheme Year
                                     exceed the percentage of his Remuneration
                                     from time to time allowed by the Board of
                                     Inland Revenue, or

                         (b)         the additional benefits derived from the
                                     Voluntary Contributions would in the
                                     Actuary's opinion be likely to cause 

                                       27
<PAGE>   35

                                     his prospective entitlement to exceed the
                                     Maximum Approvable Benefit.

             In any such case the Trustees shall arrange for Voluntary
             Contributions to be discontinued, suspended or reduced.

             (iii)       Contributions will be deducted by the Employer from the
                         remuneration payable to the Member or in such other
                         manner as the Principal Employer may decide and the
                         Trustees approve. The Employer shall account to the
                         Trustees at such intervals and by such methods as
                         comply with the requirements of section 49 of the 1995
                         Act as the Trustees in their sole discretion decide.

             (iv)        Where benefits in respect of a Member's Voluntary
                         Contributions cannot be provided without prejudicing
                         Revenue Approval the Voluntary Contributions which
                         would otherwise have had to remain unapplied shall be
                         returned to the Member or his personal representatives
                         subject to any tax charge for which the Trustees or the
                         Member may be liable.

8.04         The Trustees or other administrator of the Scheme shall comply with
             the requirements of regulation 5 of The Retirement Benefits Schemes
             (Restriction on Discretion to Approve) (Additional Voluntary
             Contributions) Regulations 1993 and where the Scheme is the Leading
             Scheme in relation to a Member, with the requirements of regulation
             6 of those Regulations so far as they concern Main Schemes. LEADING
             and MAIN SCHEME have the same respective meanings as in regulation
             2(1) of those Regulations. If those Regulations are amended or
             replaced by any other Regulations, this Rule will have effect as if
             it had been amended or replaced accordingly.

8.05         Where a Member is on leave of absence from Service, but is being
             treated as an Active Member, (Rule 5.03) the Member may continue to
             pay Voluntary Contributions while he is absent provided he
             continues to pay his ordinary contributions to the Basic Scheme.

9.01         The Member's Voluntary Contributions will at his direction be
             invested in a separately designated account or applied to provide
             life cover. The annual return on the Voluntary Contributions
             invested will be added back to the Member's account. At retirement
             or, if earlier, on the Member's death, the accumulated amount in
             the Member's account will subject to the consent of the Board of
             Inland Revenue be available to provide one or more of the following
             benefits selected by the Member:-

             (a)         additional lump sum on death;

             (b)         retirement pension;

             (c)         Spouse's and/or Dependant's pension;

             Voluntary Contributions arising under Part III of Schedule 6 to the
             Finance Act 1989.

9.02         Where the Member's Voluntary Contributions are under arrangements
             entered into on or after 8 April 1987, any retirement benefits
             secured thereby must be in the form of a non-commutable pension
             except to the extent to which the provisions of the Scheme allow
             commutation of trivial pensions or on the grounds of serious
             ill-health.

9.03         The Trustees shall ensure that the value of the additional benefits
             provided for and in respect of a Member making Voluntary
             Contributions is reasonable having regard to the amount of a
             Member's Voluntary Contributions, whether those additional benefits
             and the value of the other benefits under the Scheme take the form
             of additional years' Pensionable Service or are calculated on a
             money purchase basis.

9.04         If a Member ceases to be an Active Member and a transfer is made to
             another retirement benefits scheme or arrangement or to a Policy in
             respect of all or part of

             in respect of his Voluntary Contributions.

10.01        ORDINARY ANNUAL CONTRIBUTIONS
             Each Employer shall contribute to the Fund at the rate specified in
             the Schedule of Contributions (where applicable) together with any
             additional contributions which, acting on the advice of the Actuary
             and after consultation with the Trustees, the Principal Employer
             shall determine appropriate to secure the benefits payable under
             the Scheme in respect of those Members in or formerly in its
             Service. Unless the Trustees direct otherwise the Employer's
             contributions shall be paid to the Trustees.

10.02        ADDITIONAL SPECIAL CONTRIBUTIONS
             An Employer may at any time pay a special contribution to the Fund.
             The Trustees, having obtained the advice of the Actuary, shall
             apply the sum in accordance with the purpose stated by the Employer
             paying the contribution, provided this does not prejudice Revenue
             Approval.

                                                  the Basic Scheme, increased by

                                     (ii)         any increases awarded under

                                                  benefit or in such other
                                                  proportions as the Trustees
                                                  decide.

             (c)         REFUND OF VOLUNTARY CONTRIBUTIONS WHERE NO SPOUSE'S OR
                         CHILDREN'S PENSION OR LUMP SUM PAYABLE UNDER RULE 22.01

                         benefits scheme or arrangement approved under the Taxes
                         Act or any other scheme specifically approved for this
                         purpose by the Board of Inland Revenue, the Member may
                         ask that a transfer payment is made to the trustees of
                         that scheme or arrangement. The amount of the transfer
                         payment shall be established by the Trustees, upon the
                         advice of the Actuary, as that which is equivalent to
                         the benefits which would otherwise be payable to and in


                                       38

                         respect of the Member under the Scheme. If it exceeds

                         Employer's consent. The transfer payment shall not be
                         less than the part of the Member's Cash Equivalent
                         which the Member shall ask to be transferred subject to
                         reduction in the manner prescribed by the Occupational
                         Pension Schemes (Transfer Values) Regulations 1996. The

                         (a)         any undertaking given by the Trustees to
                                     the Board of Inland Revenue must be
                                     observed;

                         (b)         the Member's request or consent shall be
                                     required unless the requirements of the
                                     Occupational Pension Schemes (Preservation
                                     of Benefit) Regulations 1991 are satisfied;

                         (c)         the Trustees shall, if appropriate,

                                     scheme the Act and Section under which it
                                     is approved by the Board of Inland Revenue;

                         (d)         the Trustees shall certify to the trustees
                                     of the new scheme the amount of the
                                     transfer payment which is derived or deemed
                                     to be derived from contributions paid by
                                     the Member to the Scheme and shall notify
                                     the new scheme of any restriction placed on
                                     the refund of that amount;

                         (e)         the Trustees shall certify to the new

                                     the maximum permitted lump sum which can be
                                     taken in exchange for pension in respect of
                                     the transfer payment;

                         (f)         where the transfer is made to a personal
                                     pension scheme and is in respect of a
                                     Member to whom the Personal Pension Schemes
                                     (Transfer Payments) Regulations 1988 (as
                                     amended) apply, the

                                     Trustees shall issue to the Member a signed
                                     certificate showing the information 
                                     specified in those Regulations;

                         (g)         to the extent of the benefits or the Cash
                                     Equivalent to which the transfer relates,
                                     the receipt of the new scheme shall be a
                                     complete discharge to the Trustees and the
                                     Fund of all liability in respect of the
                                     Member under the Scheme and the Trustees
                                     shall be under no liability to see to the
                                     application of the amount transferred; and

                         (h)         unless the transfer is made in consequence
                                     of a valid request for a Cash Equivalent
                                     (under Rule 15.08), the Trustees shall
                                     ensure that the transfer payment is not
                                     less than the value of the benefits (or the
                                     relevant part of the benefits) payable to
                                     and in respect of the Member under the
                                     Scheme.

             (ii)        The Trustees shall not be obliged to transfer a
                         Member's Cash Equivalent to a new scheme unless the new
                         scheme is one which satisfies the requirements of
                         section 95 of the 1993 Act.

15.06        BUY-OUT UNDER SECTION 95 OF THE 1993 ACT
             (i)         As an alternative to preserved benefits or to a
                         transfer to a new scheme, a Member may ask the Trustees
                         in writing to apply the amount established by the
                         Trustees, on the advice of the Actuary, to be
                         equivalent to the Member's benefits under the Scheme in
                         buying a policy ("the Policy") from an Approved Insurer
                         providing benefits for and in respect of him in
                         substitution for the benefits otherwise payable to and
                         in respect of him under the Scheme. The sum shall not
                         be less than the part of the Member's Cash Equivalent
                         which the Member shall ask to be transferred subject to
                         reduction in the manner prescribed by the Occupational
                         Pension Schemes (Transfer Values) Regulations 1996. If
                         it exceeds that amount any excess shall be payable only
                         with the Employer's consent. The Policy shall be bought
                         with an Approved Insurer in the name of the Member or

                                       40

                         his nominee, and the Member or any other person
                         deriving rights to benefit in respect of the Member
                         shall have an absolute right to the benefits derived
                         from it. At the Member's option, the Policy may,
                         subject to the Revenue Approval not being prejudiced,
                         confer benefits or options which are alternative to the
                         benefits otherwise payable under the Scheme. Provision
                         may also be made either under the Policy or otherwise
                         for any lump sum payable on the death of the Member to
                         be held upon discretionary trusts for the benefit of
                         any one or more of the Beneficiaries (as defined in
                         Rule 22.00).

             (ii)        The Policy may include a provision which enables a
                         transfer payment to be made with the Member's written
                         consent from the Policy to a new scheme of which the
                         Member becomes a member (except that the transfer
                         payment from the Policy to a new scheme need not
                         include the guaranteed minimum pensions of a Member or
                         his Spouse) and a provision enabling benefits to be
                         provided by the purchase of another annuity, assurance
                         contract or policy from another Approved Insurer which
                         satisfies the requirements of this Rule 15.06.

             (iii)       The Trustees shall procure the issue of the Policy only
                         on terms which shall:-

                         (a)         satisfy the requirements of the Board of
                                     Inland Revenue for the purposes of
                                     section 591(2)(g) of the Taxes Act; and

                         (b)         satisfy the requirements of section 95 of
                                     the 1993 Act.

15.07        DISCHARGE OF SCHEME FROM LIABILITY
             The Member and any other person who, but for the payment of a
             transfer value or the issue of a Policy under Rules 15.05 or 15.06
             would derive rights to benefit in respect of the Member, shall have
             no claim under the Scheme to or in respect of those benefits and
             the Trustees and the Fund shall be discharged of all liability for
             payment of such benefits to the Member and any such person.

15.08        RIGHT TO CASH EQUIVALENT
             (i)         HOW TO EXERCISE THAT RIGHT
                         A Member shall exercise his right to a Cash Equivalent
                         by asking the Trustees in writing.

             (ii)        WHEN THE RIGHT IS INEFFECTIVE
                         A request is ineffective unless it, or it and another
                         valid request given to the Trustees at the same time,
                         relates to the whole of the Member's Cash Equivalent.

             (iii)       WITHDRAWAL OF REQUEST
                         A request may be withdrawn by written notice to the
                         Trustees delivered to them personally or sent by
                         registered or recorded delivery post. The notice shall
                         be ineffective if, at the time it is given, the
                         Trustees have already entered into an agreement with a
                         third party to use the whole or part of the Member's
                         Cash Equivalent to comply with the Member's request. If
                         the request is effectively withdrawn, the Member may
                         serve another request provided his right has not lapsed
                         in one of the following ways.

             (iv)        LAPSE OF RIGHT TO CASH EQUIVALENT
                         A Member's right to make a binding request lapses on
                         the earliest of:-

                         (i)         the date upon which any benefit becomes
                                     payable to him under the Scheme;

                         (ii)        the later of 1 year before the Member's

             (v)         TRUSTEES' DUTIES WHEN REQUEST FOR CASH EQUIVALENT 
                         RECEIVED

                         months of his valid application under section 93A of

                         within the period required by section 99 of the 1993

15.09        ADJUSTMENT OF CASH EQUIVALENT
             (i)         The Cash Equivalent may be increased or reduced in
                         accordance with the provisions of the 1993 Act and the
                         Occupational Pension Schemes (Transfer Values)
                         Regulations 1996.

             (ii)        If at any time it is the usual practice of the Scheme
                         to provide additional relevant benefits under Rule
                         19.05, then the Member's Cash Equivalent shall be
                         increased to take account of the additional benefits
                         which would accrue to the Member if the practice
                         continued unaltered, unless the Trustees, having taken
                         the advice of the Actuary, direct otherwise.

15.10        STATUTORY REQUIREMENTS
             The provisions of this Rule 15.00 shall be subject to any relevant
             statutory requirements for transfers, and in particular to:-

             (a)         the 1995 Act;

             (b)         the 1993 Act;

                         retirement benefits or personal pension scheme or
                         arrangement to which the Member previously belonged;
                         and

             (ii)        any cash or other assets representing the value of an
                         annuity, assurance contract or policy secured with an
                         Approved Insurer under section 591(2)(g) of the Taxes
                         Act.

16.02        The Trustees may give any relevant undertakings in respect of the
             cash or other assets and shall confer on the Member such rights and
             benefits under the Scheme as are determined by the Trustees on the
             advice of the Actuary

PROVIDED THAT:-

             (i)         the acceptance of any transfer under this Rule shall be
                         subject to any undertaking given by the Member or the
                         Trustees to the Board of Inland Revenue and to any
                         restriction of benefits required to ensure that the
                         Member's total benefits do not exceed the limits
                         imposed by Appendix C (Inland Revenue limits);

             (ii)        no part of the cash or other assets received (other
                         than any part which the transferor shall certify to be
                         derived from or deemed to be derived from contributions
                         made by the Member) shall be treated as if it had been
                         derived from contributions paid by the Member;

             (iii)       the Trustees shall have the same power to deduct tax
                         from any payment made to the Member as had the
                         transferor; and

             (iv)        the Trustees shall ascertain the period of statutory
                         Qualifying Service to which the transfer relates and
                         the maximum permitted lump sum commutation in respect
                         of the transferred amount consistent with Revenue
                         Approval.

SECTION V    BENEFITS INCREASES

18.00        AUGMENTATION OF BENEFITS

18.01        EXTENSION OF EXISTING BENEFITS AND GRANT OF NEW BENEFITS
             The Principal Employer may direct the Trustees to increase or
             extend any benefit or benefits under the Scheme, or to grant new or
             additional benefits to or in respect of any Member, employee,
             director or former employee or director, or any group of such
             persons, or to increase or extend such benefits. The Trustees shall
             implement the Principal Employer's direction if:-

             (i)         the Principal Employer pays any sum or sums which the
                         Trustees, acting on the advice of the Actuary, shall
                         require in addition to the Employer's ordinary
                         contributions under Rule 10.01, or if the Actuary
                         certifies that the Fund is sufficient without any
                         additional payment, and

             (ii)        if the increase, extension or grant would not prejudice
                         Revenue Approval.

             The Principal Employer may agree with the Member that it will make
             such a direction to the Trustees provided that the cost of so doing
             is shared with the Member concerned.

19.00        INDEXATION

19.01        Any increase in the pension payable to or in respect of a Member
             under this Rule shall apply to the whole of it.

             Where a Member or his Spouse or Dependant is receiving a pension
             under the Scheme, his pension shall be increased on the first day
             of any Scheme Year by the percentage (if any) determined under Rule
             19.03.


                                       46
<PAGE>   54

19.03        AMOUNT OF INCREASE
             The annual rate of increase (if any) shall be the lesser of:-

             (a)         the percentage increase in the Price Index during the 
                         previous calendar year, or

             (b)         5%.

19.04        PRESERVED PENSIONS NOT YET IN PAYMENT
             A preserved pension shall be increased in respect of the period
             after Active Membership ceases up to its payment date or the
             earlier date of the Member's death by the same percentage increase
             which applied in the relevant Scheme Year to pensions in payment.

19.05        DISCRETIONARY INCREASES
             The Principal Employer shall regularly review pensions in payment
             and may direct the Trustees that the pensions of Members formerly
             in its employment shall be increased to a greater extent than set
             out above. The Principal Employer may make a similar direction in
             respect of preserved pensions and may apply different rates of
             increase to each category. The Trustees shall implement the
             Principal Employer's direction if:-

             (i)         the Principal Employer pays any sum or sums which the
                         Trustees, acting on the advice of the Actuary, shall
                         require in addition to the Employer's ordinary
                         contributions under Rule 10.01, or if the Actuary
                         certifies that the Fund is sufficient without any
                         additional payment, and

             (ii)        if the increase, extension or grant would not prejudice
                         Revenue Approval.

19.06        PROPORTIONATE INCREASE WHERE ACTIVE MEMBERSHIP CEASES
             When Active Membership has ceased during the previous Scheme Year,

SECTION VI   OPTIONS FOR ALTERNATIVE BENEFITS

20.00        EXCHANGING PENSION FOR LUMP SUM

20.01        HOW OPTION IS EXERCISED
             A Member whose pension becomes payable may, subject to the
             provisions of this Rule 20.00, elect to give up part of his pension
             in exchange for a lump sum. This option shall be exercisable by
             written notice to the Trustees and shall take effect on the date
             the Member's pension is due to begin.

20.02        CALCULATION OF LUMP SUM
             The factors to be employed in converting pension into lump sum
             benefit under this Rule are set out in Appendix B.

20.03        LUMP SUM AVAILABLE IN SPECIAL CIRCUMSTANCES: EXCEPTIONAL ILL-HEALTH
             Upon the application of or on behalf of any Member entitled to the
             payment of a pension under the Scheme who is in exceptionally
             serious ill-health (as to which the decision of the Trustees shall
             be final) the Trustees may decide to grant to that Member a lump
             sum payment instead of his pension and any contingent death
             benefits. The amount of the lump sum shall be certified as
             reasonable by the Actuary. An appropriate deduction shall be made
             for tax (Rule 28.00).

20.04        LUMP SUM AVAILABLE IN SPECIAL CIRCUMSTANCES: PENSION OF 
             TRIVIAL AMOUNT
             Where a pension payable to or in respect of a Member is of a
             Trivial Amount, the Trustees may decide to grant to the Member or
             other person a lump sum payment payable on the date the Member's
             pension is due to commence instead of the Member's pension and any
             contingent death benefits. This shall not apply to any pension
             remaining after a Member exercises his option to take a lump sum
             under this Rule. The factors to be employed in converting pension
             into lump sum benefit under this Rule are set out in Appendix B. An
             appropriate deduction shall be made for tax (Rule 28.00).



                                       48
<PAGE>   56

20.05        LIMIT ON LUMP SUM: REVENUE RESTRICTION
             The amount of the lump sum which a Member may take in exchange for
             pension shall not exceed the Maximum Approvable Benefit except
             where the Member is in exceptionally serious ill-health.

21.00        SURRENDERING PENSION TO PROVIDE A SPOUSE'S OR DEPENDANT'S PENSION

21.01        A Member whose pension becomes payable may, subject to the
             provisions of this Rule 21.00, elect in writing to the Trustees to
             surrender part of his pension to provide a pension arising after
             his death for the benefit of his Spouse and/or one or more
             Dependants. That pension shall be payable for life.

21.02        The following conditions apply to the surrender:-

             (i)         the amount of the pension that may be surrendered (when
                         aggregated with any pension surrendered under the Basic
                         Scheme) shall not be more than the total pension
                         remaining payable to the Member under the Scheme and
                         under the Basic Scheme (together with the annuity value
                         of any pension given up for a lump sum), nor shall it
                         result in the Member's own pension being of a Trivial
                         Amount;

             (ii)        arrangements satisfactory to the Trustees shall have
                         been made in respect of any liability for inheritance
                         tax or any similar tax;

             (iii)       in the case of a Dependant, the consent of the Trustees
                         to that person's nomination shall be necessary. Their
                         consent shall not be given unless they are satisfied
                         that the nominee is a person to whose maintenance or
                         support the Member is contributing or has contributed;
                         and

             (iv)        the Trustees may ask the Member to produce a
                         certificate of good health regard being taken of his
                         age from a medical practitioner nominated by 

                                       49
<PAGE>   57

                         the Trustees, and the surrender shall not take effect
                         unless they are satisfied on this point.

21.03        The pension resulting from the surrender shall take effect only if
             the Member's Spouse or nominated Dependant survives the Member.
             Should the Spouse or Dependant die after the Member's own pension
             has started to be paid, the Member's pension shall not on this
             account be increased.

21.04        The amount of the pension shall be established by the Trustees on
             the advice of the Actuary having regard to the amount of the
             pension surrendered under the Scheme and the respective ages of the
             Member and the Spouse or Dependant at the date on which the
             Member's own pension begins to be paid.

21.05        The option shall be exercisable by written notice to the Trustees
             specifying the amount of pension to be surrendered. Notice must be
             served not earlier than 2 months before nor later than 1 month
             after the Member's pension is due to begin, although the Trustees
             may at their discretion accept a later notice. Once the option has
             been exercised it may not be revoked without the consent of the
             Trustees, unless before the date on which the Member's pension is
             due to begin either:-

             (i)         the Member or his Spouse or nominated Dependant should
                         die; or

             (ii)        the nominee is the Member's Spouse and the marriage
                         between them is dissolved;

             If this happens, the notice shall be automatically cancelled.

                         under Rule 22.02 of the WWPS Deed or (ii) the Spouse's
                         long-term pension under Rules 17.04 or 17.05 of the
                         WWMIS Deed as appropriate, subject to the requirements
                         for Revenue Approval. In the case of a WWMIS Member the
                         Spouse's pension under this Rule shall not come into
                         payment until the Spouse's said long-term pension does.

             (ii)        ADJUSTMENT OF PENSION BECAUSE OF DISPARITY IN AGE
                         Where the Member's Spouse was born 10 or more years
                         earlier or later than the Member, the pension shall be
                         reduced or increased respectively by 2.5 per cent for
                         every complete year (and proportionately for any period
                         of less than a complete year) in excess of 10.

22.03        CHILDREN'S PENSIONS
             (i)         ENTITLEMENT TO PENSION
                         Subject to paragraph (ii), where an Active Member dies
                         in Service and is survived by a Child a pension shall
                         be payable to or for the benefit of that Child and one
                         other Child.

             (ii)        AMOUNT OF PENSION
                         (a)         Where a Spouse's pension is payable, the
                                     annual rate of pension payable to or for
                                     the benefit of each Child under this Rule
                                     shall be equal to the amount (if any) by
                                     which 10% of Final 

                                       52
<PAGE>   60

                                     Pensionable Salary exceeds (i) the Child's
                                     pension under Rule 22.03 of the WWPS Deed
                                     or (ii) the Eligible Child's long-term
                                     pension under Rule 17.08 of the WWMIS Deed
                                     as appropriate, subject to the requirements
                                     for Revenue Approval. In the case of a
                                     WWMIS Member, the Eligible Child's pension
                                     under this Rule shall not come into payment
                                     until the Eligible Child's said long-term
                                     pension does.

                         (b)         Where no Spouse's pension is payable, the
                                     annual rate of pension payable to or for
                                     the benefit of each Child calculated in
                                     accordance with paragraph (a) of this Rule
                                     22.03(ii) shall be doubled, subject to the
                                     requirements for Revenue Approval.

             (iii) ALLOCATION WHERE THERE ARE MORE THAN 2 ELIGIBLE CHILDREN
                         Where there are more than 2 eligible Children, the
                         total available pension shall be shared equally between
                         them or for their benefit or in such other proportions
                         as the Trustees decide.

23.00        DEATH OF MEMBER IN RECEIPT OF PENSION

23.01        LUMP SUM
             If a Member who is receiving a pension under the Scheme dies within
             5 years of the date payment began, a lump sum equal in value to any
             further instalments of pension which would have been payable to the
             Member under the Scheme and the Basic Scheme had he survived until
             that 5th anniversary, reduced by any lump sum payable in that event
             under the Basic Scheme, shall become payable. The Trustees shall
             hold the lump sum under the Scheme on discretionary trusts, as
             described in Rule 22.01 (iii). In calculating the amount of the
             lump sum, any increase in the rate of the Member's pension
             applicable before he died shall be included.

23.02        SPOUSE'S PENSION
             (i)         ENTITLEMENT TO AND AMOUNT OF PENSION
                         Subject to the following paragraphs of this Rule, if a
                         Member dies while he is receiving a pension under the
                         Scheme an annual pension shall be paid to his Spouse.
                         The pension shall equal two-thirds of the Member's
                         total pension he was receiving under the Scheme and the
                         Basic Scheme at the date of his death (having taken
                         account of any actuarial reduction or increase and the
                         exercise of any lump sum or surrender option) reduced
                         by the Spouse's pension under the Basic Scheme. In the
                         case of a WWMIS Member the Spouse's pension shall not
                         come into payment until the Spouse's long-term pension
                         under Rule 18.03 of the WWMIS Deed does.

             (ii)        ADJUSTMENT OF SPOUSE'S PENSION
                         Where the Member's Spouse was born 10 or more years
                         earlier or later than the Member, the pension under the
                         Scheme shall be reduced or increased respectively by
                         2.5 per cent for every complete year (and
                         proportionately for any period for less than a complete
                         year) in excess of 10.

23.03        CHILDREN'S PENSIONS
             (i)         ENTITLEMENT AND AMOUNT
                         If a Member who is receiving a pension under the Scheme
                         dies and is survived by a Child a pension shall be
                         payable to or for the benefit of a Child and any one
                         other Child. Where a Spouse's pension is payable the
                         annual rate of the pension payable to or for the
                         benefit of each Child shall be one-sixth of:-

                         (i)         the Member's total pension under the Scheme
                                     and the Basic Scheme, increased by

                         (ii)        any increases awarded under Rule 19.00.

             This amount shall then be reduced by the amount of the Child's
             pension under the Basic Scheme.

                                       54

<PAGE>   62

             If no pension is payable to a surviving Spouse, the annual rate of
             each Child's pension shall be one-half of:-

             (i)         the Member's total pension under the Scheme and the 
                         Basic Scheme, increased by

             (ii)        any increases awarded under Rule 19.00.

             This amount shall then be reduced by the amount of the Child's
             pension under the Basic Scheme.

             In the case of a WWMIS Member a Child's pension under this Rule
             shall not come into payment until his Eligible Child's long-term
             pension under Rule 18.05 of the WWMIS Deed does.

             (ii)        ALLOCATION WHERE THERE ARE MORE THAN 2 ELIGIBLE 
                         CHILDREN
                         Where there are more than 2 eligible Children, the
                         total available pension shall be shared equally between
                         them or for their benefit, or in such other proportions
                         as the Trustees decide.

SECTION VIII PAYMENT OF BENEFITS

24.00        PAYMENT OF PENSIONS

24.01        MEMBER'S PENSION
             Subject to Rule 12.02(iii) any pension payable under the Scheme
             shall be payable to the Member for life by monthly instalments in
             arrear or at such other intervals as the Trustees may decide and
             notify to him. The last instalment shall be that payable on the
             normal payment date coinciding with or immediately following the
             date of the Member's death. No apportionment shall be made to the
             date of death.

24.02        SPOUSE'S AND DEPENDANT'S PENSIONS
             Any Spouse's pension payable under the Scheme (Rules 15.04, 22.00
             and 23.00) shall be payable for life (unless he or she remarries)
             by monthly instalments in arrear or at such other intervals as the
             Trustees may decide and notify to the recipient. The first
             instalment shall be payable from (i) the day following the date of
             the Member's death (in the case of a WWPS Member) or (ii) the day
             on which the Spouse's long-term pension comes into payment under
             the appropriate Rule of the WWMIS Deed (in the case of a WWMIS
             Member). The last instalment shall be that payable on the normal
             payment date coinciding with or immediately following the date of
             the recipient's death or remarriage. No apportionment shall be made
             to the date of death or remarriage. If the Spouse remarries the
             Trustees may at their discretion adjust the amount of or continue
             to pay the Spouse's pension. If the Spouse's remarriage comes to an
             end, the Trustees may at their discretion reinstate the Spouse's
             pension in whole or in part.

24.03        CHILDREN'S PENSIONS
             Any pension payable under the Scheme to or for the benefit of a
             Child shall be payable from (i) the day following the date of the
             Member's death (in the case of a WWPS Member) or (ii) the day on
             which the Eligible Child's long-term pension comes into payment
             under the appropriate Rule of the WWMIS Deed (in the case of a
             WWMIS Member). The last instalment of a Child's pension shall be
             that payable on the normal payment date coinciding with or
             immediately following the date the 

                                       56
<PAGE>   64

             Child ceases to qualify as such. If when the Member died there were
             3 or more Children who shared the aggregate sum available for only
             2 Children and 1 or more ceases to be a Child, the Trustees shall
             reallocate the total sum amongst those still eligible.

             Where pensions are payable to or for the benefit of 2 Children,
             there shall be no reallocation of the benefit payable to the other
             Child when the pension payable to the other ceases.

24.04        METHOD OF PAYMENT
             All pensions payable under the Scheme shall be paid by bank
             transfer or in any other way which the Trustees may agree with the
             recipient.

24A.00       DISCRETION TO PAY SPOUSE'S PENSIONS TO COMMON LAW SPOUSE OR 
             DEPENDANT

24A.01       TRUSTEES' GENERAL DISCRETION
             In the event of the death of a Member (while in Service or
             retirement, or otherwise having ceased to be an Active Member) the
             Trustees shall have the following discretions in relation to any
             Spouse's pension which is payable under the Rules of the Scheme.

24A.02       DISCRETION WHERE NO SPOUSE'S PENSION PAYABLE
             Where a Member dies without leaving a Spouse but leaving a Common
             Law Spouse and/or one or more Dependants, the Trustees may, in
             their absolute discretion, award in such proportions as they shall
             decide all or part of the pension which would otherwise have been
             payable to the Member's Spouse to his Common Law Spouse and/or
             Dependant or Dependants.

24A.03       DISCRETION WHERE SPOUSE'S PENSION IS PAYABLE
             Where the Member was separate from his Spouse at the date of his
             death, but was then living with a Common Law Spouse or leaves one
             or more Dependants the Trustees may, in their absolute discretion,
             award in such proportions as they shall 

                                       57

<PAGE>   65


             decide some or all of the Spouse's pension to the Member's Common
             Law Spouse and/or Dependant or Dependants instead of the Member's
             Spouse.

25.00        MINORITY OR INCAPACITY OF BENEFICIARY

25.01        If a person entitled to benefit under the Scheme is a minor, or is
             in the Trustees' opinion suffering from any physical or other
             incapacity which means that he cannot manage his affairs or give a
             proper receipt, the Trustees may pay that benefit to the person's
             Spouse or to any one or more of his Dependants, or to any bank or
             institution or other person or persons to be applied for his
             benefit. Payment duly made in good faith in this way shall operate
             as a complete discharge to the Trustees or body making payment for
             the money so paid, and the Trustees or other body shall not be
             under any liability to enquire into the application of the money
             paid.

25.02        The Trustees shall also have power to declare in respect of any
             benefit payable under the Scheme or any part of those benefits,
             such trusts, terms and limitations including such provisions for
             maintenance, education or advancement or for accumulation of any
             income during a minority and including such discretionary trusts
             and powers as the Trustees shall from time to time by deed
             revocable or irrevocable appoint. In exercise of their powers, the
             Trustees shall not infringe the rule against perpetuities, and any
             trusts, terms or limitations so declared shall be constituted and
             administered separately from the trusts of the Scheme. The Trustees
             shall have power to appoint as trustees of those benefits or part
             of those benefits any 2 persons or a corporate trustee (whether or
             not being a trust corporation) and to remove any such trustees and
             appoint any other trustees in place of any one so removed.

26.00        UNCLAIMED BENEFITS

26.01        Provided the Trustees have taken all reasonable steps to pay or
             procure the payment of any pension or other benefit payable under
             the Scheme (including a refund of the Member's contributions) or
             any instalment of it to the person entitled to that pension or
             benefit, if it remains unpaid, and is not claimed by the person
             entitled to it for a period of 6 years from the date it became
             payable, then the Trustees shall return any moneys forming the
             whole or part of that pension or other benefit or instalment to the
             Fund and the pension or benefit shall immediately cease to be
             payable.

SECTION IX   MISCELLANEOUS

27.00        TRUSTEES' DISCRETION ON NOTICES AND TIME LIMITS

27.01        Any notice required by statute shall be given to the appropriate
             person in the prescribed form and the prescribed manner. Subject to
             this, where the Rules provide for notices to be given to the
             Trustees, the Trustees shall decide the manner in which any such
             notice should be given. They shall also have power to vary any time
             limit specified in the Rules.

28.00        TAX

28.01        Tax shall be deducted from benefits and any other payments in all
             cases where the Trustees have a liability to account for it.

29.00        INHERITANCE TAX

29.01        Where liability to inheritance tax or other similar tax or duty
             arises in respect of any Scheme benefit, the Trustees may either
             apply the benefit or part of it in payment of such tax or duty
             (including any interest due on it) and deduct the amount paid from
             the benefit, or postpone paying the benefit until any question
             regarding the incidence of the tax or duty has been resolved.

30.00        PROHIBITION OF ASSIGNMENT AND FORFEITURE OF BENEFITS

30.01        PROHIBITION OF ASSIGNMENT OF BENEFITS
             No person may in any way assign or charge his beneficial interest
             under the Scheme. If he attempts to do so, or becomes bankrupt or
             does or allows any act which would result in that person's benefit
             being payable wholly or partly to some other person, his benefit
             shall be forfeited. This shall not apply where the person is
             exercising a Scheme option. The Trustees may apply the benefit in a
             case of hardship for the maintenance and personal support of the
             person whose benefits are liable to forfeiture and his Spouse or
             Dependants or one or more of them. The Trustees may do so in 

                                       59
<PAGE>   67


             any way they think fit, except that they shall not make any payment
             to or for the benefit of a person in whose favour the attempted
             assignment or charge was to have been made.

30.02        FORFEITURE OF BENEFITS
             Any benefit payable or prospectively payable under the Scheme to or
             in respect of a Member may at the Trustees' discretion be forfeited
             or cease to be payable (as the case may be) where the person
             entitled has been convicted of one or more offences:-

             (a)         which are committed before the benefit becomes payable,

                                     manslaughter of that Member or any other
                                     offence of which unlawful killing of that
                                     Member is an element.

31.00        DISMISSAL OF EMPLOYEES: DEDUCTIONS FROM BENEFIT

31.01        Nothing in the Scheme  shall in any way  restrict or fetter the 
             right of the  Employers to dismiss any employee.


                                       60
<PAGE>   68

31.02        No Member or other person shall have any claim, right or interest
             upon, to or in respect of the Fund or any interest in it, except in
             accordance with the provisions of the Scheme.

31.03        In the event of a Member ceasing to be in Service because of his
             dismissal (including constructive dismissal) for any reason, the
             resulting cessation of his Active Membership shall not be a ground
             for any damages or any increase in damages in any action brought
             against the Employer or otherwise in respect of the Member's
             dismissal.

31.04        Subject to the requirements of section 93 of the 1995 Act, in a
             case where a Member is under some monetary obligation to an
             Employer arising out of a criminal, negligent or fraudulent act or
             omission on his part, the Employer shall be entitled to claim from
             the Trustees an amount equal to the amount of the obligation not
             exceeding the Member's interest in the Scheme. On proof of the
             amount being due, the Trustees shall so far as possible procure the
             payment of the claim to the Employer out of any moneys due under
             the Scheme to the Member as determined by the Actuary. Any rights
             of the Member under the Scheme shall accordingly be reduced except
             that the Employers shall have no such right in respect of a
             transfer payment to the Fund.

31.05        The Trustees shall certify to the Member the amount recovered and
             its effect upon his Scheme benefits. It shall be open to the Member
             to agree in writing with the Trustees some alternative method of
             recovery. If there is a dispute as to the amount due, the Employer
             shall not be entitled to exercise its right of recovery until the
             debt in question has become enforceable under a court order, the
             award of an arbitrator or (in Scotland) an arbiter. In any such
             instance, payment of benefits under the Scheme may be postponed
             until it has become clear whether the debt is enforceable or not.

32.00        RIGHT TO INFORMATION

32.01        Members and other beneficiaries shall be entitled to the
             information in the form and in the manner prescribed from time to
             time by law.

             As at the date an Employer withdraws from the Scheme under Rule
             33.03 the Principal Employer shall determine on the advice of the

             Employer. The Segregated Fund shall not without the consent of the
             Principal Employer exceed the lesser of:-

             (a)         the Members' Cash Equivalents (less the value of the
                         liabilities for guaranteed minimum pensions where these
                         are retained by the Scheme) and

             (b)         the amount found by relating the total Fund assets to
                         total Fund liabilities and applying that proportion to
                         the accrued liabilities of the Members concerned

             as at that date.

             For the purpose of this Rule "Employer" includes any undertaking or
             business carried on by any of the Employers.

             The costs, charges and expenses relating to this Rule shall be
             borne by the Segregated Fund and the Fund in the proportion
             determined by the Principal Employer.

             proportion of the Fund determined under Rule 33.06 applied:

             (a)         by a transfer of assets in accordance with Rule 15.05;
                         or

In addition to the definitions in Appendix A, the following definitions apply to
this Appendix:-

"AGGREGATE RETIREMENT BENEFIT" means the total of

         contract approved under the Taxes Act or a Personal Pension insofar as
         those benefits are secured in respect of Service; and

(ii)     the pension value of a Member's Lump Sum Retirement Benefit. In
         calculating the amount of the Aggregate Retirement Benefit of a 1989
         Member who ceases to be in Active Membership on or after 31st August

         is one twelfth of its total cash value.

"ASSOCIATED EMPLOYMENT" shall mean two or more concurrent employments held by
the Member which are associated, i.e. where

(i)      there is a period where the Member has held all of them,

(ii)     the period counts under the Scheme in the case of all of them as a
         period in respect of which benefits are payable, and

         of Service.

<PAGE>   89


"CONNECTED SCHEME" means any Relevant Scheme which is connected to the Scheme in
relation to a Member, i.e if

(i)      there is a period during which the Member has been employed by two of
         the Employers

(ii)     the period counts under both schemes as a period in respect of which
         benefits are payable and

(iii)    the period counts under one scheme for Service with one Employer and
         under the other scheme for Service with the other Employer.

"FINAL REMUNERATION" is the greater of

(i)      the Member's fixed remuneration from the Employer for any one of the
         five years before Active Membership ends, plus the yearly average of
         fluctuating earnings for the three years (or other period decided by
         the Trustees as would not affect Revenue Approval) before the end of
         that year and

(ii)     the average of the Member's total earnings from the Employers for any
         three or more consecutive years in the ten years before Active
         Membership ends

(a)      for a Member in Service whose remuneration has been substantially
         reduced due to Incapacity for a period of more than ten years before
         Active Membership ends, Final Remuneration may be calculated at the
         date when the Member's remuneration was first reduced, and then
         increased in accordance with the Price Index

(b)      where Final Remuneration is calculated using a year other than the
         twelve months before Active Membership ends, the Member's actual
         remuneration for that year may be increased in proportion to any rise
         in the Price Index from the last day of that year up to the end of
         Active Membership.



                                       82
<PAGE>   90

         For a pre-1987 Member, this method may only apply to the calculation of
         the maximum amount of the cash payment for the purposes of Revenue
         Limitations if it is also used to increase the Member's pension
         benefits in the same proportions.

(c)      an early retirement pension from the Employers may not be included in
         Final Remuneration

(d)      No account will be taken of any earnings connected with shares or the

         calculated as in (ii) above

         Retirement Benefit the maximum Final Remuneration is (pound)100,000 (or
         other figure prescribed in a Treasury order). This restriction shall
         not apply to a pre-1987 Member.

(g)      For a 1989 Member the maximum Final Remuneration shall not exceed the
         Permitted Maximum and

(h)      the total amount of any profit-related pay (whether relieved from
         income tax or not), and benefits in kind assessed for tax under
         Schedule E (or in other circumstances agreed with the Inland Revenue),
         may be included under (i) and (ii) above and treated as fluctuating

         (a)      from the Employer and

         (b)      in respect of any Associated Employment or any Connected 
                  Scheme

         which are assessable to income tax under Schedule E but excluding any
         earnings connected with shares or the right to acquire shares or
         anything where tax is chargeable under Section 148 of the Taxes Act. No
         earnings in excess of the Permitted Maximum are included.

(ii)     for a pre-1989 Member total earnings from the Employers in the year in
         question which are assessable to income tax under Schedule E but

         include a period of service for an employer who is associated with the
         Principal Employer by virtue of a permanent community of interest
         rather than because one employer is controlled by the other or both are
         controlled by a third party. Where both such employers are
         participating in the Scheme separate calculations of maximum benefits
         are required in respect of the separate periods of Service. For the
         purpose of this paragraph, "control" has the meaning in section 840 of
         the Taxes Act or, in the case of a close company, section 416 of the

treated as a 1989 Member at any time before benefits commence, are bought out or
otherwise transferred from the Scheme or the attainment of age 75, whichever
first occurs.

                  actual date of retirement; or

                  (c) on leaving Active Membership before attaining age 75, a
                  pension of l/60th of Final Remuneration for each year of
                  Service (not exceeding 40 years) or such greater amount as
                  will not prejudice Revenue Approval. The amount computed as
                  aforesaid may be increased by 5% for each complete year or, if
                  greater, in proportion to any increase in the Price Index
                  which has occurred between the date of termination of Active
                  Membership and the date on which the pension begins to be
                  payable. Any further increase necessary to comply with DSS
                  requirements is also allowable.

2.       Subject always to the provisions of Rule 9.02 (relating to the
         provision of non-commutable pensions by Members' voluntary

         exceed:-
  
                  (a)    on retirement at any time between attaining age 50 and

                         exceeding 40 years) or such greater amount as will not 
                         prejudice Revenue Approval; or

                  (b)    on retirement at any time before Normal Retirement Date
                         on grounds of Incapacity, the amount which could have
                         been provided at Normal Retirement Date in accordance
                         with 2(a) above; Final Remuneration being computed as
                         at the actual date of retirement; or

                  (c)    on leaving Active Membership before attaining age 75, a
                         lump sum of 3/80ths of Final Remuneration for each year
                         of Service (not exceeding 40 years) or such greater
                         amount as will not prejudice Revenue Approval. The
                         amount computed as aforesaid may be increased in
                         proportion to any increase in the Price Index which has
                         occurred between the date of termination of Active
                         Membership and the date on which the pension begins to
                         be payable but only if and to the same extent as the
                         total benefits have been increased under l(c) above.
                         Provided always that the provisions of this paragraph
                         2. shall not apply to a pension commuted on the grounds
                         of triviality.

3.       The lump sum benefit (exclusive of any refund of a Member's own
         contributions and any interest thereon), payable on the death of a
         Member while in Service or who having left Active Membership dies
         before the commencement of pension shall not, when aggregated with all
         like benefits under Associated Schemes, exceed 4 times Final
         Remuneration (excluding anything under paragraph (d) of the definition
         of Final Remuneration) or, if greater, (pound)5,000, less

         (i)      any lump sum (other than a refund of a Member's own
                  contributions) payable on the death of the Member under all
                  Relevant Schemes in respect of service with previous
                  employers, and

         (ii)     any lump sum life assurance benefit payable (other than a
                  refund of contributions or premiums paid by the Member) on the
                  death of the Member under a retirement annuity contract or
                  trust scheme approved under Chapter III of Part XIV of the
                  Taxes Act or a Personal Pension

                                       87
<PAGE>   95

                  if the aggregate of such lump sums exceeds (pound)2,500.

4.       Any pension for a spouse or a Dependant of the 1989 Member, when
         aggregated with the pensions, other than those provided by surrender of
         a Member's own pension, payable to that spouse or Dependant under or
         arising from all Associated Schemes, shall not exceed an amount equal
         to 2/3rds of the Aggregate Retirement Benefit -

         (a)      being paid to the Member at the date of death (including any
                  pension increases), or

         (b)      being a deferred benefit payable to the Member at any time
                  between attaining age 50 and attaining age 75, or

         (c)      prospectively payable to a Member, if the Member dies in
                  Service, if the Member remained in Service up to Normal
                  Retirement Date at the rate of pay in force immediately before
                  the Member's death, or

         (d)      prospectively payable to the Member on death in Service after
                  Normal Retirement Date on the basis that retirement took place
                  on the day before the date of death,

         or such greater amount as will not prejudice Revenue Approval.

         If pensions are payable to more than one Dependant of a Member, the
         aggregate of all spouse's pensions and Dependants' pensions so payable
         under or arising from this and all Associated Schemes shall not exceed
         the full amount of whichever is the appropriate Aggregate Retirement
         Benefit under (a), (b), (c) or (d) above or such greater sum as will
         not prejudice Revenue Approval.

5.       The maximum amount of a pension ascertained in accordance with this
         section A, less any pension which has been commuted for a lump sum or
         given up in order to provide an annuity for a Dependant, may be
         increased by 3% for each complete year or, if 

                                       88
<PAGE>   96

         greater, in proportion to the increase in the Price Index which has 
         occurred, since the pension commenced to be paid.

6.       The preceding provisions of this section A shall be modified in their
         application to a Member who is or has been during membership of the
         Scheme a Special Director so that the amount of the maximum Aggregate
         Retirement Benefit in 1. and of the maximum Lump Sum Retirement Benefit
         in 2. shall be reduced, where necessary for continuance of Revenue
         Approval, so as to take account of any corresponding benefits under
         either a retirement annuity contract or trust scheme approved under
         Chapter III of Part XIV of the Taxes Act or a Personal Pension.

7.       Where, in addition to being a Member, the 1989 Member is also a member
         of a FSAVCS, the provisions of the following sentence shall apply in
         relation to any augmentation of the benefits provided for the Member by
         the Scheme after withdrawal from the Scheme. Any provisions in the
         Scheme imposing a limit on the amount of a benefit provided for the
         Member shall have effect (notwithstanding anything in them to the
         contrary) as if they provided for the limit to be reduced by the amount
         of any like benefit provided for the Member by the FSAVCS.

8.       For a 1989 Member, the Scheme provisions shall have effect
         (notwithstanding anything in them to the contrary) as if they provided
         that a Member's retirement benefit shall be paid no later than the date
         on which he attains age 75.

9.       If the 1989 Member elects to take any part of the benefits under the
         Scheme in advance of actual retirement, the limits set out in 1. and 2.
         above shall apply as if the Member had retired at the effective date of
         the election as aforesaid, no account being taken of subsequent
         Service, except that the maximum amount of any uncommuted pension not
         commencing immediately may be increased either actuarially in respect
         of the period of deferment or in proportion to any increase in the
         Price Index during that period.

                         Revenue Approval.

         If pensions are payable to more than one spouse and Dependant
         aforesaid, the aggregate of all spouse's pensions and Dependants'
         pensions so payable under or arising from this and all Associated

         the Scheme in advance of actual retirement, the limits set out in (1)
         and (2) above shall apply as if the Member had retired at the effective
         date of the election as aforesaid, no account being taken of subsequent
         Service, except that the maximum amount of any uncommuted pension not
         commencing immediately may be increased either actuarially in respect

         Price Index during that period.

(7)      The preceding provisions of this section shall be modified in their
         application to a Member who is or has been during membership of the
