                                  AZURIX CORP.

                                PROXY STATEMENT

     This proxy statement and the accompanying form of proxy are being furnished
to the shareholders of Azurix Corp. ("Azurix") in connection with a solicitation
of proxies by the Board of Directors of Azurix to be used at the 2000 Annual
Meeting of Shareholders to be held in the LaSalle Ballroom of the Doubletree
Hotel at Allen Center, 400 Dallas Street, Houston, Texas, at 10:00 a.m. Houston
time on Tuesday, June 13, 2000. The mailing address of the principal executive
offices of Azurix is 333 Clay Street, Suite 1000, Houston, Texas 77002-7369.
This proxy statement and the related proxy are being first sent or given to
shareholders on or about May 1, 2000.

     All shares represented by a properly executed proxy in the accompanying
form received in time for the meeting, and not revoked, will be voted. Unless
the shareholder otherwise specifies therein, such shares will be voted by the
persons named as proxy holders:

          FOR the election of the two nominees for director named in this proxy
     statement;

          FOR approval of the Azurix Corp. 1999 Stock Plan; and

          FOR ratification of the appointment of Arthur Andersen LLP as Azurix's
     auditors for the year ending December 31, 2000.

     Any shareholder giving a proxy may revoke it at any time provided written
notice of such revocation is received by Azurix's Corporate Secretary before
such proxy is voted; otherwise, if received in time, properly completed proxies
will be voted at the meeting in accordance with the instructions specified
thereon. Shareholders attending the meeting may revoke their proxies and vote in
person.

RECORD DATE AND VOTING AT THE MEETING

     Holders of record at the close of business on April 17, 2000, the record
date, of Azurix's common stock (the "Common Stock") will be entitled to one vote
per share on all matters submitted to the meeting. At the close of business on
the record date, there were issued and outstanding 117,149,885 shares of Common
Stock entitled to vote. The holders of a majority of the shares entitled to
vote, whether present or represented by proxy, will constitute a quorum for the
transaction of business at the meeting. There are no other voting securities
outstanding.

     Directors will be elected by a plurality of the votes cast at the meeting.
This means the two management nominees will be elected if they receive more
affirmative votes than any other nominees. A shareholder entitled to vote for
the election of directors can withhold authority to vote for all nominees for
director or can withhold authority to vote for certain nominees for director.
Only votes cast for a nominee will be counted, except that the accompanying
proxy will be voted for the two management nominees unless the proxy contains
instructions to the contrary. Abstentions and broker nonvotes will not be
counted and will have no effect on the outcome of the vote for directors. A
broker nonvote occurs when a broker submits a proxy that does not indicate a
vote for some of the proposals because the beneficially owners have not
instructed the broker on how to vote on such proposals and the broker does not
have discretionary authority to vote in the absence of instructions.

     Approval of the Azurix Corp. 1999 Stock Plan and ratification of Arthur
Andersen LLP as Azurix's auditors for the year ending December 31, 2000 each
require the affirmative vote of the holders of a majority of the shares of
Common Stock present in person or by proxy and entitled to vote at the meeting.
For these
<PAGE>   4

proposals, an abstention will have the same legal effect as a vote against the
proposal. Broker nonvotes will not be counted as a vote for or against these
proposals.

ANNUAL REPORT

     Azurix's annual report to shareholders for the year ended December 31,
1999, including financial statements, is being mailed herewith to all
shareholders entitled to vote at the annual meeting. The annual report does not
constitute a part of the proxy soliciting material.

                                    ITEM 1.

                             ELECTION OF DIRECTORS

     In accordance with Azurix's Restated Certificate of Incorporation, the
Board of Directors is divided into three classes, each of which serves for a
three-year term. Two directors are to be elected at the meeting. John H. Duncan
and Joseph W. Sutton are being nominated to serve until the annual meeting of
shareholders to be held in 2003 and until their respective successors have been
duly elected and qualified. Each of the nominees currently serves as a director
of Azurix. Although the Board of Directors does not expect either of the
nominees to become unable to serve, if such a situation should occur before the
meeting, it is expected that either (a) the persons named in the proxy will vote
for another nominee designated by the Board of Directors, or (b) the authorized
number of directors will be reduced accordingly. Proxies cannot be voted for a
greater number of persons than the number of nominees named on the enclosed form
of proxy. Shareholders may not cumulate their votes in the election of
directors.

     The following information regarding the nominees for director and the other
directors, their principal occupations, employment history and directorships in
certain companies is as reported by the respective nominees and other directors.

     Nominees for director for three-year terms ending in 2003:

DIRECTORS' COMPENSATION

     On the date of Azurix's initial public offering, each nonemployee director
of Azurix received a grant of options to purchase 12,000 shares of Common Stock.
Each nonemployee director who served as chairman of a committee received an
additional 1,500 options. These grants were made under the Azurix Corp. 1999
Stock Plan at an exercise price of $19.00 per share, the initial public offering
price to shareholders. The number of options granted was determined using a
Black-Scholes equivalent theoretical stock option value and are exercisable for
10 years. Nonemployee director's compensation (annual service and meeting fees)
is targeted at the 75th percentile of the market for companies of similar size
to Azurix and is paid 100% in options to purchase shares of Common Stock.
Nonemployee director grants are made annually following Azurix's annual meeting
of shareholders and approval by the Board of Directors. If an individual is
appointed to the Board of Directors at a time other than the annual meeting of
shareholders, the newly appointed director may receive a grant of options at the
time such individual joins the board. Employee directors do not receive
additional compensation for serving on the Board of Directors or its committees.

ATLANTIC WATER TRUST

     Atlantic Water Trust, a Delaware business trust, currently owns 78,536,532
shares of Common Stock. Each of Enron and Marlin Water Trust owns a 50% voting
interest in Atlantic Water Trust. Each of Marlin Water Trust and Enron has the
right and power at all times to appoint up to 50% of the members of the board of
directors of Atlantic Water Trust. Holders of Marlin Water Trust trust
certificates are entitled to exercise Marlin Water Trust's appointment rights.
If the Marlin Water Trust certificateholders defer exercising their appointment
rights, Enron has the right to appoint such members, but Marlin Water Trust has
the right, at any time, without cause, to remove any such members. To date,
Enron has appointed all of the directors of Atlantic Water Trust.

     As long as Atlantic Water Trust owns a majority of Azurix's 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 Azurix's 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 Azurix's 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 the event that Azurix were to issue a class of preferred
stock, then, in each case, Marlin Water Trust's right to designate directors
would be reduced by the number of directors that may be elected by the Azurix
preferred stock holders 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 shares of
Common Stock. Under the terms of the Atlantic Water Trust agreement, Enron can
be prevented from appointing more than half of Azurix's directors

                             EXECUTIVE COMPENSATION

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The following report has been provided by Azurix's Human Resources and
Compensation Committee (the "Committee") of the Board of Directors in accordance
with current proxy statement disclosure requirements. The members of the
Committee are John H. Duncan (Chairman) and Herbert S. Winokur, Jr.

     This material states Azurix's current overall compensation philosophy and
program objectives. Detailed descriptions of Azurix's compensation programs are
provided as well as information on Azurix's 1999 pay levels for the Chief
Executive Officer (the "CEO").

OVERALL OBJECTIVES OF THE EXECUTIVE COMPENSATION PROGRAM

     Azurix's compensation philosophy and program objectives are directed by two
primary guiding principles. First, the program is intended to provide
competitive levels of compensation, at expected levels of performance, in order
to attract, motivate and retain talented executives. Second, the program is
intended to create an alignment of interests between Azurix's executives and
shareholders such that a significant portion of each executive's compensation is
directly linked to maximizing shareholder value.

     In support of this philosophy, the executive compensation program is
designed to reward performance that is directly relevant to Azurix's success. As
such, Azurix attempts to provide incentive pay that varies based on corporate
and individual performance.

     To accomplish these objectives, the Committee has structured the executive
compensation program with three primary underlying components: base salary,
annual incentives and long-term incentives (i.e., stock options). Certain other
executive benefits are also provided. The following sections describe Azurix's
plans by element of compensation and discuss how each component relates to
Azurix's overall compensation philosophy.

     In reviewing this information, reference is often made to the use of
competitive market data. Azurix does not target a specific level of the market
for determining pay; rather, it reviews market data from the 50th to 90th
percentiles and evaluates performance in determining incentive compensation
levels. Several market data sources are used by Azurix. As a start-up company in
an acquisition growth mode, there was no effort made to assess how Azurix's
executive pay levels compared to the levels of pay provided by the companies in
the proxy peer group that is used in Azurix's total shareholder return graph,
since these companies vary significantly in size and scope of operations.
Instead, Azurix primarily utilized published survey data and data obtained from
independent consultants that are for general industry companies similar in size
(i.e., revenues) to Azurix. The

                                        8
<PAGE>   11

published surveys include data on over 50 companies of comparable size to
Azurix, as measured by revenues. Emphasis is placed on the published data and
data obtained from consultants rather than on the data for proxy peers, since
the published data and consulting data are reflective of company size.

BASE SALARY PROGRAM

     Azurix's base salaries for named executive officers, in aggregate, fall at
the market 50th percentile. Azurix periodically reviews its executive pay levels
to assess consistency with the external market. We believe it is crucial to
provide competitive salaries over time in order to attract and retain executives
who are highly talented and capable of creating added shareholder value.

     Annual salary adjustments for Azurix are based on several factors: general
levels of market salary increases, individual performance, competitive base
salary levels and Azurix's overall financial results. Azurix reviews performance
considering total shareholder return, the level of recurring earnings, cash flow
and individual performance. These criteria are assessed qualitatively and are
not weighted. All base salary increases are based on a philosophy of
pay-for-performance and perceptions of an individual's long-term value to
Azurix. As a result, employees with higher levels of performance sustained over
time will be paid correspondingly higher salaries.

ANNUAL BONUS PLAN

     In 1999, Azurix did not have in place a formal annual bonus plan. Instead,
given that Azurix was in its first year of operation, the Committee evaluated
Azurix's level of recurring earnings and cash flow and determined that no cash
bonuses should be paid to named executive officers of Azurix for 1999 results.
In making this determination, the Committee took into account that Azurix's
performance on other factors (such as share price) fell well below expectations.
Thus, the zero cash bonus payments emphasized Azurix's philosophy of
pay-for-performance.

     In December 1999, Azurix made a stock option grant to named executive
officers (other than the CEO). These grants had an expected value of about
50%-60% of the target bonus for the officers. These awards were intended to
provide incentive opportunities tied to share price growth in lieu of any cash
bonuses for named executive officers. These December 1999 grants vest at the end
of six years, but vesting is accelerated if certain recurring net income
objectives as agreed to by the Board of Directors are achieved.

     Azurix has put in place a short-term incentive plan structure for the year
2000, excluding the CEO, that is tied to company financial results and
individual performance. This plan provides for 50% of an employee's annual
incentive opportunity to be tied to individual goals that are operational and
financial in nature. This portion of the annual incentive will be payable in
cash. The remaining 50% of the annual incentive opportunity (on an expected
value basis) will be payable in Azurix stock options. These stock options vest
in 2006; however, vesting is accelerated if Azurix achieves certain net income
objectives tied to Azurix's business plan. Thus, employees will receive value
from this portion of the annual incentive program only if Azurix's stock price
rises, and employees will be able to exercise these options before six years
after grant only if a net income objective as established annually by the Board
of Directors is achieved. The CEO's bonus plan is based upon the accomplishment
of company and individual goals and objectives with payments purely at the
discretion of the Committee.

LONG-TERM INCENTIVE PLAN

     Azurix's Long-Term Incentive Plan ("LTIP") is designed to focus executive
efforts on the long-term goals of Azurix and to maximize total return to our
shareholders. While Azurix's LTIP allows the Committee to use a variety of
long-term incentive devices, to date the Committee has relied solely on stock
option awards to provide long-term incentive opportunities to named executive
officers. (However, a limited number of restricted shares were issued to
selected Azurix executives to replace cash balance plan retirement benefits that
Azurix terminated in 1999.)

                                        9
<PAGE>   12

     Stock options align the interests of employees and shareholders by
providing value to the executive through stock price appreciation only. All
stock options have a 10-year term before expiration and the most recent grants
are fully vested over a period of three to six years from the date of grant.

     Stock options were granted to the named executive officers in 1999 and it
is anticipated that stock option awards will be made periodically at the
discretion of the Committee in the future. The stock option grants made in
February 1999 were front-loaded multi-year awards equal to about three times the
market 75th percentile. This grant was intended to provide management with a
significant stake in creating shareholder value. The three-year front-load
feature of the grant is consistent with the common market practice of making
large front-loaded grants at the time of an initial public offering ("IPO"). The
market price of Azurix Common Stock is currently below the exercise price of
these options.

     Azurix also made a special grant of 50,000 options each to Ms. Martin and
Mr. Skellett in December 1999 to recognize their performance and expected future
contributions to Azurix. These options vest at the end of six years; however,
vesting is accelerated if certain recurring net income objectives as agreed to
by the Board of Directors are achieved.

     The Committee believes stock options are an important part of Azurix's
total executive pay program, since employees only receive income from the
options if Azurix's share price rises.

STOCK OWNERSHIP

     As a part of aligning rewards to executives and returns to shareholders, in
February 2000, the Committee approved stock ownership guidelines providing that,
within two years, the Chairman and CEO be required to own Azurix stock having a
value equal to at least two times her annual base salary and each other Section
16(b) officer (as defined by the Securities Exchange Act of 1934, as amended) is
required to own Azurix stock having a value equal to at least 50% of his or her
annual base salary. For purposes of these guidelines, ownership includes grants
of restricted stock but does not include grants of stock options.

1999 CHIEF EXECUTIVE OFFICER PAY

     As previously described, the Committee considers several factors in
developing an executive's compensation package. For the CEO, these include
competitive market practices (consistent with the philosophy described for other
executives), experience, achievement of strategic goals and the financial
success of Azurix.

     Ms. Mark's annual salary was not adjusted in 1999. The CEO's base salary is
slightly below the market median.

     Ms. Mark received no annual bonus for 1999 since Azurix's aggregate
performance on the measures described in the annual bonus section of this report
were well below aggressive internal company targets.

     The Committee granted stock options for two million shares to Ms. Mark in
February 1999 as an incentive to increase shareholder value. These awards are
tied to performance in that the executive only realizes income from stock
options if the stock price rises. The grant was a multi-year award at the 75th
percentile of the market, which is consistent with common IPO market practice.
Ms. Mark also received 5,450 shares of restricted stock to compensate her for
the terminated cash balance retirement plan, as previously described.

$1 MILLION PAY DEDUCTIBILITY CAP

     Under Section 162(m) of the Internal Revenue Code, public companies are
precluded from receiving a tax deduction on compensation paid to executive
officers in excess of $1 million, unless the compensation is qualified as
performance-based compensation under Section 162(m). Compensation related to
stock options and restricted stock under the Azurix Corp. 1999 Stock Plan does
not currently qualify as performance-based compensation under Section 162(m). To
qualify as performance-based compensation shareholder approval and certain other
requirements must be met. The Board of Directors has made recent amendments to
the plan designed to comply with the requirements of 162(m) and will present the
plan to shareholders at the 2000

                                       10
<PAGE>   13

annual meeting for approval and adoption. The Committee believes that if the
plan is approved by shareholders, future compensation related to stock options
and performance-based restricted stock granted under the plan would be fully
deductible as performance-based compensation.

SUMMARY

     The Committee is responsible for establishing compensation programs which
link rewards to the executives and returns to shareholders. By year-end 1999,
Azurix Common Stock decreased substantially from its June 1999 IPO price. As a
result, no cash bonuses were paid to Azurix named executive officers and their
December 1999 stock option grants (excluding the CEO) accelerate vesting based
solely on the financial performance of Azurix. In addition, long-term
compensation stock option grants to Azurix officers throughout 1999 have
resulted in no additional income due to the decrease in shareholder return.
Consequently, Azurix officers received only base salary in 1999. While we are
disappointed with the decreased shareholder return, we believe the compensation
plan designs do link to shareholder return and the Committee believes that the
Azurix management team will be more focused on increasing shareholder returns in
2000 and beyond.

(1) Options are granted at the market price of Azurix Common Stock on the date
    of grant.

(2) The 0%, 5% and 10% assumed annual rates of compounded stock price
    appreciation are mandated by the rules of the Securities and Exchange
    Commission. There can be no assurance that the actual stock price
    appreciation over the 10-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.

EMPLOYMENT AGREEMENTS

     Ms. Mark entered into an employment agreement with Enron, effective May
1998 and expiring December 31, 2001, as Chairman of Enron International and Vice
Chairman of Enron. The agreement was amended when it was assumed by Azurix,
effective February 1, 1999, in connection with Ms. Mark's assumption of the role
as Chairman and Chief Executive Officer of Azurix, in addition to her role as
Vice Chairman of Enron. The agreement provides for an annual salary of not less
than $710,000. The agreement stipulates that bonus calculations for 1999 through
2001 will be determined prospectively. The agreement provides that Ms. Mark is
eligible to participate in either the Enron executive compensation long-term
incentive program or the Azurix stock incentive plan. The agreement also
provides for full vesting of specific grants and awards made to Ms. Mark under
long-term incentive plans maintained by Enron in the event of involuntary
termination, death or disability and, as recently amended, precludes full
vesting of long-term grants made under the Azurix stock incentive plan in the
event of termination. The agreement provides 100% of base pay and unpaid bonuses
through the contract term in the event of involuntary termination. The
employment agreement contains noncompetition provisions in the event of Ms.
Mark's termination of employment.

     Mr. Skellett entered into an employment agreement with Wessex Water Ltd
which entitles Mr. Skellett to an annual salary of L254,000 ($410,590). The

options to purchase 600,000 shares of Common Stock at an exercise price of
$16.72 per share, which options vest 33 1/3% per year over three years. The
employment agreement may be terminated by either Wessex or Mr. Skellett upon
twelve months' notice. The agreement otherwise terminates on Mr. Skellett's 60th
birthday. The agreement provides that Mr. Skellett will participate in an annual
bonus plan. The agreement prohibits Mr. Skellett from competing with Wessex for
one year following termination of employment.

     Ms. Martin entered into an employment agreement with Enron Capital & Trade
Resources Corp., which subsequently was assigned to Azurix. The agreement runs
through August 31, 2003, and entitles Ms. Martin to an annual salary of
$400,000. In connection with the transfer of her agreement to Azurix, Ms. Martin
received a bonus of $350,000. The agreement provides that Ms. Martin will
participate in an annual incentive plan with a bonus target of between 100% and
200% of her annual base salary and that Ms. Martin is eligible to participate in
the Azurix stock incentive plan. Under her agreement, Ms. Martin was granted
stock options to purchase 1,000,000 shares of Common Stock at an exercise price
of $16.72 per share, which options vest 25% per year over four years. If Ms.
Martin is involuntarily terminated, which includes a termination by Azurix
without cause, then she will receive a monthly severance payment equal to 100%
of her monthly salary and unpaid annual bonuses until the end of the term of the
agreement as if she had not been terminated. In order to receive these payments,
Ms. Martin may not compete with Azurix during the term of the agreement
following an involuntary termination. The agreement also prohibits Ms. Martin
from competing with Azurix until six months after the termination of employment
or the expiration of the agreement.

     Mr. Ale entered into an employment agreement with Azurix effective December
10, 1998, which runs through December 10, 2001. The agreement entitles Mr. Ale
to an annual salary of $340,000 and provides that Mr. Ale will participate in an
annual incentive plan with a bonus target of 100% of his annual base salary. The
agreement also provides that Mr. Ale is eligible to participate in the Azurix
stock incentive plan. Under his agreement, Mr. Ale was granted stock options to
purchase 250,000 shares of Common Stock at an exercise price of $16.72 per
share, which options vest 25% per year over four years. If Mr. Ale is
involuntarily terminated, which includes a termination by Azurix without cause,
then he will receive a monthly severance payment equal to 100% of his monthly
salary and annual bonus payments until the end of the term of the agreement as
if he had not been terminated. The agreement prohibits Mr. Ale from competing
with Azurix until the later of December 10, 2001 or one year following
termination of his employment.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During 1999, as a result of the extensive relationship among Azurix, Enron,
Atlantic Water Trust and Marlin Water Trust, Azurix entered into various
agreements. The following summaries of these agreements discuss the material
provisions of these agreements and are qualified completely by reference to the
full text of these agreements, copies of which have been filed as exhibits to
Azurix's Annual Report on Form 10-K for the fiscal year ended December 31, 1999.

     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 employees of our
operating subsidiaries, are covered by various employee benefit plans of Enron
such as 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 paid approximately $72 million on behalf of Azurix to fund its
general, administrative and operating expenses from Azurix's inception on
January 29, 1998 through June 7, 1999, in addition to capital expenditures. This
included $28.5 million advanced to Azurix by Enron in connection with Azurix's
investment in a water and wastewater concession in Cancun, Mexico in December
1998, as well as advances relating to services provided to Azurix by Enron. The
amount paid by Enron was non-interest bearing and had no maturity date. Azurix
used a portion of the net proceeds received from its initial public offering to
repay this amount.

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 existed 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 contained in its certificate of incorporation
permits it to engage in the businesses of acquiring, owning, operating, and
managing water resources and 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.

                                       19
<PAGE>   22

     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 (i) approved by special approval
(the approval by a majority of the directors of Azurix not associated with
Enron); (ii) on terms no less favorable to Azurix than those generally being
provided to or available from unrelated third parties; and (iii) fair to Azurix,
taking into account the totality of the relationships between the parties
involved, including other transactions that may be particularly favorable or
advantageous to Azurix.

     Enron may adopt a resolution or course of action that has not received
special approval. Enron and any person voting in connection with a special
approval will be authorized in connection with its determination of what is
"fair and reasonable" to Azurix and in connection with its resolution of any
conflict of interest to consider (i) the relative interests of any party to such
conflict, agreement, transaction or situation and the benefits and burdens
relating to such interest; (ii) any customary or accepted industry practices and
any customary or historical dealings with a particular person; (iii) any
applicable generally accepted accounting or engineering practices or principles;
and (iv) 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 (i) 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 (ii) 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 AGREEMENTS

     Effective May 1, 1999, Azurix and Enron entered into an agreement 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
and training and other benefits programs. Azurix may also utilize Enron's
regulatory affairs, marketing affairs, treasury and risk assessment and control
departments. In addition, Azurix may continue to participate in portions of
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's corporate staff and
support services that it utilizes. This overhead charge will be allocated based
upon factors such as employee headcount, payroll and square footage. Azurix
believes the allocation methods and costs are reasonable. Costs for services
used under the agreement were approximately $5.2 million in 1999. The services
agreement with Enron is for an indefinite term, but may be terminated on 180
days' notice.
                                       20
<PAGE>   23

Azurix currently has a sublease arrangement, and intends to enter into a
sublease agreement, with Enron providing for the use of office space in Houston,
Texas.

     Azurix also entered into separate agreements with Enron that allowed Azurix
to use Enron's corporate aircraft on a time-sharing basis. These agreements
permitted Azurix to use any of the aircraft when available as determined by
Enron. For each flight conducted, Azurix was required to pay all flight
expenses, including the cost of returning the aircraft, and an additional fee
equal to 100% of the fuel, oil, lubricants and other additives used during the
flight. During 1999, Azurix incurred approximately $1.4 million in expenses
under these agreements. These agreements terminated on February 20, 2000.

CREDIT AGREEMENT

     Effective May 1, 1999, Azurix entered into a credit agreement with Enron,
which was amended as of January 4, 2000. Under this agreement, Enron will
provide funds to Azurix for general, administrative and operating expenses,
including interest expenses. The credit agreement matures on the earlier of
December 15, 2001 or 90 days following the date that Enron and its affiliates do
not own or have the power to vote at least one-third of Azurix's capital stock
ordinarily entitled to vote for the election of directors and fewer than one-
third of Azurix's directors are officers, directors or employees of Enron or its
affiliates. The total commitment under the credit agreement is $180 million.
Advances under the facility will bear interest at the U.S. 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 reborrowed during the term of the credit agreement. The principal amount
outstanding under the credit agreement is limited to no more than $120 million
at any time during calendar year 2000 (unless Enron otherwise agrees in its sole
discretion) and $180 million at any time during calendar year 2001. As of
December 31, 1999, $53.3 million was 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 (i) 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 (ii) 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. Azurix's share of such costs will be pro rata based on its earnings
before interest and taxes. Azurix does not anticipate that its share of such
costs will be material.

REGISTRATION RIGHTS AGREEMENT

     Azurix entered into an agreement with Atlantic Water Trust that allows
Atlantic Water Trust to request Azurix to register 78,536,532 shares of Common
Stock owned by Atlantic Water Trust. Atlantic Water Trust has the right to
request one such registration during each 12-month period following the date of
the initial public offering of Common Stock, June 9, 1999, plus one additional
registration. The number of shares requested to be registered shall have an
aggregate offering price of at least $25 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 Azurix in the future. Azurix has
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

                                       21
<PAGE>   24

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.

LETTER OF CREDIT OBLIGATIONS

     Enron has made available letters of credit on behalf of Azurix's
subsidiaries in the aggregate amount of approximately $16 million as of December
31, 1999. Azurix has paid, or reimbursed Enron for, the fees associated with
these letters of credit.

GUARANTEE OF AZURIX NORTH AMERICA DEBT

     Enron guaranteed debt and letter of credit obligations of up to $25 million
of Azurix North America to Comerica Bank under the terms of September 29, 1999
credit facilities in exchange for, among other things, the elimination of
requirements for various assets to be pledged. As of December 31, 1999, $6.7
million of indebtedness and $16.4 million of letter of credit obligations were
outstanding under these facilities, and thus guaranteed by Enron. Azurix paid to
Enron an initial fee of approximately $63,000 in respect of this guarantee.
These credit facilities were terminated as of March 31, 2000.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires officers and directors of Azurix and persons who
beneficially own more than 10% of the Common Stock to file reports of ownership
and changes in ownership concerning the Common Stock with the Securities and
Exchange Commission and to furnish Azurix with copies of all Section 16(a) forms
they file. Based upon Azurix's review of the Section 16(a) filings that have
been received by Azurix, Azurix believes that all filings required to be made
under Section 16(a) during 1999 were timely made.

                                       22

                                    ITEM 2.

                        APPROVAL OF THE 1999 STOCK PLAN

     In February 1999, prior to Azurix's initial public offering, Azurix
established the Azurix Corp. 1999 Stock Plan (the "Plan"). The purposes of the
Plan are (i) to enhance Azurix's ability to attract and retain the services of
qualified key employees, officers and directors upon whose judgment, initiative
and efforts the successful conduct and development of Azurix's business largely
depends, and (ii) to provide additional incentives to such persons to devote
their utmost effort and skill to the advancement and betterment of Azurix, by
providing them an opportunity to participate in the ownership of Azurix and
thereby have an interest in the success and increased value of Azurix. Grants
under the Plan can take the form of stock options or awards of restricted stock.
As of December 31, 1999, options to purchase approximately 10,253,357 shares of
Common Stock and 121,895 shares of restricted stock had been granted under the
Plan.

     On May 1, 2000, the Human Resources and Compensation Committee recommended,
and the Board of Directors adopted certain amendments to the Plan and
recommended that the Plan, as amended and restated, be presented to shareholders
at the 2000 Annual Meeting of Shareholders. The Plan is being proposed to
shareholders in order to qualify the Plan under Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code"). The amendments adopted by the
Board of Directors on May 1, 2000 were principally designed to comply with the
requirements of Section 162(m) and do not increase the number of shares
available under the Plan. In addition, certain other amendments to the Plan were
approved by the Board that it believes are appropriate to update the Plan in
light of Azurix's becoming a publicly held corporation during 1999 and to obtain
approval of the Plan by the U.K. Inland Revenue under the U.K. Income and
Corporate Taxes Act 1988.

     During 1999 and 2000, the Committee granted stock options and shares of
restricted stock under the Plan to eligible individuals, including grants to
"covered employees" within the meaning of Section 162(m) of the Code. Whether or
not Azurix's shareholders approve the Plan, stock options previously granted
under the Plan will remain outstanding and become exercisable pursuant to the
terms of the Plan and shares of restricted stock granted under the Plan will
vest in accordance with the terms of the Plan. However, if the Plan is not
approved by shareholders, Azurix will not be permitted to make any further
grants under the Plan.

     The closing price of the Common Stock on the New York Stock Exchange on
April 26, 2000 was $7.1875 per share.

     The material features of the Plan are discussed below. The discussion is
qualified in its entirety by reference to the full text of the Plan. A copy of
the Plan, as amended and restated, is attached to this proxy statement as
Exhibit A.

MATERIAL FEATURES OF THE PLAN

     Participation and Administration. Employees of Azurix and its subsidiaries
and employees of Enron and its subsidiaries who perform services for Azurix are
eligible to participate in the Plan. The Human Resources and Compensation
Committee administers the Plan. The Committee is authorized to establish
administrative rules, to designate individuals to receive awards and the size of
such awards and to set the terms and conditions of such awards. Committee
members are required to be "non-employee directors" within the meaning of Rule
16b-3 under the Exchange Act and "outside directors" within the meaning of
Section 162(m) of the Code.

     Nonemployee directors of Azurix are also eligible to participate in the
Plan. Under the Plan, grants to nonemployee directors are administered by the
full Board of Directors. Azurix currently has six nonemployee directors. For
information regarding the annual grant of stock options to nonemployee
directors, see "Directors' Compensation" above.

     Shares Subject to the Plan. The maximum number of shares of Common Stock
that may be issued under the Plan is 17,583,284 shares, of which 25% may be
granted in the form of restricted stock and options for up to 7,500,000 shares
may be granted in the form of incentive stock options. As of December 31, 1999,

                                       23
<PAGE>   26

approximately 7,208,032 shares remained available under the Plan. In the event a
stock option or restricted stock grant can no longer under any circumstances be
exercised or any shares of Common Stock are reacquired by Azurix pursuant to a
stock option or restricted stock agreement, the shares of Common Stock allocable
to the unexercised portion of such option or restricted stock grant will be
available for future grants or issuances under the Plan.

     Stock Option Grants to Employees. Stock options granted under the Plan may
be in the form of either incentive stock options within the meaning of Section
422 of the Code or non-qualified stock options. As to grants of stock options to
employees, the Committee establishes the exercise price, which may not be less
than the fair market value of the shares of Common Stock on the date of grant.
The Committee also sets the term and provisions for termination of each option,
provided that no option may be exercisable more than ten years after the date it
is granted. No grantee may receive options for more than 2,000,000 shares in any
single calendar year.

     Restricted Stock Grants to Employees. The Committee may issue to employees
grants of restricted stock. Restricted stock grants consist of shares of Common
Stock that are issued subject to such terms, restrictions and conditions as the
Committee may determine at the time of grant. The Committee is also authorized
to make grants of restricted stock which qualify as performance-based
compensation under Section 162(m) of the Code, such that (i) the issuance is
contingent upon attainment of pre-established performance criteria or (ii)
restrictions lapse contingent upon attainment of pre-established performance
criteria. The performance criteria to be used will be one or any combination of
the following: recurring after tax net income and/or cash flow at the Azurix
and/or subsidiary level, and earnings per share and/or total shareholder return
at the Azurix level, as determined at the sole discretion of the Committee. With
respect to grants of restricted stock qualifying as performance-based
compensation under Section 162(m) of the Code, no individual shall receive a
grant totaling more than 100,000 shares in any single year.

     Stock Option Grants to Nonemployee Directors. As to grants of stock options
to nonemployee directors, the Plan will be administered by the full Board. The
Board selects the persons to receive stock option grants, determines the number
of shares to be awarded and sets the terms and provisions of each option granted
to nonemployee directors.

     Adjustments. The Plan provides for adjustment of the aggregate number of
shares reserved for issuance under the Plan and the number of shares subject to
any outstanding option upon the occurrence of certain corporate transactions
affecting Azurix's capitalization. These transactions include, among other
things, extraordinary cash dividends, stock dividends, stock splits,

     Change in Control. In the event of (i) a Change in Control of Azurix (as
described in Section 8.2 of the Plan) or (ii) a Change in Control of Enron at
any time when Enron, directly or indirectly, owns 30% or more of the capital
stock of Azurix (as described in Section 8.1 of the Plan), then (a) any
outstanding shares of restricted stock shall be surrendered to Azurix and each
grantee shall receive a cash payment by Azurix in the an amount equal to the
number of shares of restricted stock surrendered multiplied by the fair market
value of a share of Common Stock and (b) all outstanding options shall be
surrendered to Azurix and each grantee shall receive a cash payment by Azurix in

     Termination and Amendments. The Plan terminates on February 1, 2009 and no
stock options or grants of restricted stock may be awarded after that date. The

may be made under the Plan, or (iv) increase the maximum number of options or
shares of restricted stock any individual can receive in a single calendar year.

SECTION 162(m) OF THE INTERNAL REVENUE CODE.

     Section 162(m) precludes a public corporation from taking a deduction for
compensation in excess of $1 million paid to its chief executive officer or any
of its four other highest-paid officers. However, compensation that qualifies
under Section 162(m) as "performance-based" is specifically exempt from the
deduction limit. Based on Section 162(m) and the regulations issued thereunder,
Azurix believes that compensation generated in connection with the exercise of
stock options that are granted under the Plan following shareholder approval of
the Plan should qualify as performance-based compensation and, accordingly,
Azurix's deductions for such compensation should not be limited by Section
162(m). The Plan has been designed to provide flexibility with respect to
whether restricted stock awards will qualify as performance-based compensation
under Section 162(m). Azurix believes that following shareholder approval of the
Plan certain awards of restricted stock under the Plan will so qualify and
Azurix's deductions with respect to such awards should not be limited by Section
162(m). However, certain awards of restricted stock will not qualify as
performance-based compensation, even following shareholder approval of the Plan,
and, therefore, Azurix's compensation expense deductions relating to such awards
will be subject to the Section 162(m) deduction limitation.

UNITED STATES FEDERAL INCOME TAX ASPECTS OF THE PLAN

     Generally, no federal income tax is imposed on the optionee upon the grant
of a non-statutory stock option. In addition, Azurix is not entitled to a tax
deduction by reason of such a grant. Generally, upon the exercise of a
non-statutory stock option, the optionee will be treated as receiving
compensation taxable as ordinary income in the year of exercise in an amount
equal to the excess of the fair market value of the shares on the date of
exercise over the option price paid for such shares.

     Upon the exercise of a non-statutory stock option, Azurix may claim a
deduction for compensation paid at the same time and in the same amount as
compensation income is recognized to the optionee assuming any federal income
tax withholding requirements are satisfied. Upon a subsequent disposition of the
shares received by the optionee upon exercise of a non-statutory stock option,
any appreciation after the date of exercise should qualify as a capital gain.

     The incentive stock options under the Plan are intended to constitute
"incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code. Incentive stock options are subject to special federal income tax
treatment. No federal income tax is imposed on the optionee upon the grant or
exercise of incentive stock options if the optionee does not dispose of shares
acquired pursuant to the exercise within the two-year period beginning on the
date the option was granted or within the one-year period beginning on the date
the option was exercised (collectively, the "holding period"). If these
conditions are met and no tax is imposed on the optionee, then Azurix would not
be entitled to any deduction for federal income tax purposes in connection with
the grant or exercise of the option or the disposition of the underlying shares.
With respect to an incentive stock option, the difference between the fair
market value of the stock on the date of exercise and the exercise price
generally must be included in the optionee's alternative minimum taxable income.

                                       25
<PAGE>   28

     Upon disposition of the shares received upon exercise of an incentive stock
option after the holding period, the difference between the amount realized and
the exercise price should constitute a long-term capital gain or loss to the
optionee. If an optionee disposes of shares acquired pursuant to the exercise of
an incentive stock option prior to the end of the holding period, the optionee
will be treated as having received, at the time of disposition, compensation
taxable as ordinary income. In such event, Azurix may claim a deduction for
compensation paid at the same time and in the same amount as compensation is
treated as received by the optionee. The amount treated as compensation is the
excess of the fair market value of the shares at the time of exercise (or in the
case of a sale in which a loss would be recognized, the amount realized on the
sale if less) over the exercise price, and any amount realized in excess of the
fair market value of the shares at the time of exercise would be treated as
short-term or long-term capital gain, depending on the holding period of the
shares.

     An individual who has been granted restricted stock under the Plan will not
realize taxable income at the time of grant, and Azurix will not be entitled to
a deduction at that time, assuming that the restrictions constitute a
substantial risk of forfeiture for federal income tax purposes. Upon expiration
of the forfeiture restrictions (i.e., as shares become vested), the holder will
realize ordinary income in an amount equal to the excess of the fair market
value of the shares at such time over the amount, if any, paid for such shares,
and, subject to the application of Section 162(m), Azurix will be entitled to a
corresponding deduction. Dividend equivalents, if any, accrued and paid to the
holder during the period that the forfeiture restrictions apply will also be
treated as compensation income to the holder and deductible as such by Azurix.

     However, the recipient of restricted stock may elect to be taxed at the
time of grant of the restricted stock based upon the fair market value of the
shares on the date of the award. If the recipient makes this election, (a)
Azurix will be entitled to a deduction at the same time and in the same amount
(subject to the limitations contained in Section 162(m)), (b) dividends, if any,
paid to the recipient during the period the forfeiture restrictions apply will
be taxable as dividends and will not be deductible by Azurix, and (c) there will
be no further federal income tax consequences when the forfeiture restrictions
lapse.

OF THE AZURIX CORP. 1999 STOCK PLAN.

adjustment as to number and kind of shares in the same manner as pursuant to
Section 4.3 hereof, of the Company's authorized shares of Common Stock may be
issued under the Plan, of which twenty five percent (25%) may be granted in the
form of Restricted Stock and Options for up to 7,500,000 shares may be granted

kind of shares in the same manner as pursuant to Section 4.3 hereof.

     For purposes of this limitation, in the event that (a) all or any portion
of any Option or Restricted Stock granted or offered under the Plan can no
longer under any circumstances be exercised, or (b) any shares of Common Stock

Plan.

     4.2  Accounting for Grants. For purposes of this Article 4, if a grant
under this Plan is denominated in shares of Common Stock, the number of shares
covered by such grant, or to which such grant relates, shall be counted on the
date of grant against the aggregate number of shares of Common Stock available
for making grants under the Plan; provided, however, that grants that operate in
tandem with (whether granted simultaneously with or at a different time from)
other grants may be counted or not counted under procedures adopted by the
Committee in order to avoid double counting.

     4.3  Adjustments. In the event that the Committee shall determine that any
dividend or other distribution (whether in the form of cash, shares of Common
Stock, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of shares of Common Stock or other
securities of the Company, issuance of warrants or other rights to purchase
shares of Common Stock or other securities of the Company (or other similar
corporate transaction or event) affects the shares of Common Stock such that an
adjustment

                                       A-3
<PAGE>   34

is determined by the Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the Committee may, subject to Section 4.4, in such manner
as it may deem equitable, adjust any or all of (a) the number and type of shares
of Common Stock (or other securities or property) which thereafter may be made
the subject of grants made under the Plan, (b) the number and type of shares of
Common Stock (or other securities or property) subject to outstanding grants
made under the Plan, and (c) the purchase or exercise price with respect to any
grant made under the Plan, or, if deemed appropriate, make provision for a cash
payment to the holder of an outstanding grant made under the Plan; provided,
however, that with respect to grants of Incentive Stock Options, no such
adjustment shall be authorized to the extent that such adjustment would cause
the Plan to violate Section 422(b)(1) of the Code or any successor provision
thereto; and provided further, that the number of shares of Common Stock subject
to any grant made under the Plan denominated in shares of Common Stock shall
always be a whole number.

     4.4  If, and whenever, prior to the expiration of a grant theretofore made,
the Company shall effect a subdivision or consolidation of shares of Common
Stock or the payment of a stock dividend on shares of Common Stock without
receipt of consideration by the Company, the number of shares of Common Stock
with respect to which such grant may thereafter be vested or exercised (a) in
the event of an increase in the number of outstanding shares of Common Stock
shall be proportionately increased, and if the grant is an Option the purchase
price per share shall be proportionately reduced, and (b) in the event of a
reduction in the number of outstanding shares of Common Stock shall be
proportionately reduced, and if the grant is an Option the purchase price per
share shall be proportionately increased.

                                   ARTICLE 5

                                    OPTIONS

     5.1  Option Agreement. Each Option granted pursuant to this Plan shall be
evidenced by an Option Agreement which shall specify the number of shares
subject thereto, vesting provisions relating to such Option, the Exercise Price
per share, and whether the Option is an Incentive Option or Nonqualified Option.
As soon as is practical following the grant of an Option, an Option Agreement
shall be duly executed and delivered by or on behalf of the Company to the
Optionee to whom such Option was granted. Each Option Agreement shall be in such
form and contain such additional terms and conditions, not inconsistent with the
provisions of this Plan, as the Administrator shall, from time to time, deem
desirable. Each Option Agreement may be different from each other Option
Agreement. No individual shall be granted Options totaling more than 2,000,000
shares of Common Stock in any single calendar year.

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

     5.3  Time and Method of Exercise. Subject to the provisions contained in
the Plan and in a Participant's Option Agreement, unexercised vested shares of
Common Stock under an Option may be exercised in whole or in part from time to
time by request to the Company. Payment of the exercise price and any applicable
tax withholding amounts must be made at the time of exercise, in whole or in
part, by delivery of a cashier's check or shares of Common Stock, or any
combination thereof having a Fair Market Value equal to such exercise price
provided that the Fair Market Value of shares of Common Stock so delivered shall
be equal to the closing price of such shares as reported in the
"NYSE -- Composite Transaction" section of the Midwest Edition of the Wall
Street Journal on the date of actual receipt by the Company of the notice
exercising the Option or, if no prices are so reported on such day, on the last
preceding day on which such prices of shares of Common Stock are so reported. An
Option may be exercised through a broker financed exercise pursuant to the
provisions of Regulation T of the Federal Reserve Board. If the Company receives
                                       A-4
<PAGE>   35

payment of the purchase price for the exercise of the Option through a broker
financed exercise before the end of the third business day following the
broker's execution of the sale of shares of Common Stock for the financed
exercise, the exercise shall be effective at the time of such sale. Otherwise,
the exercise shall be effective when the Company receives payment of the
purchase price.

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

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

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

     5.7  Nontransferability of Options. No Option shall be assignable or
transferable except pursuant to the provisions of Section 11.1 of this Plan and
no Incentive Option may be transferred by the Optionee other than by will or the
laws of descent and distribution.

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

     5.9  Grants to Residents and Citizens of Foreign Countries. Notwithstanding
anything to the contrary in this Article 5, the Committee may, in its
discretion, grant Options to residents and to citizens of countries other than
the United States of America with the requirement that the exercise thereof be
required to be made through a broker financed exercise as referenced in Section
5.3 above.

                                   ARTICLE 6

                                RESTRICTED STOCK

     6.1  Grants of Restricted Stock. A grant of Restricted Stock pursuant to a
Restricted Stock Agreement entitles the recipient to acquire shares of Common
Stock subject to such terms, restrictions and conditions as the Administrator
may determine at the time of grant.

     6.2  Grants of Performance Based Restricted Stock. The Committee is
authorized to make grants of Restricted Stock which qualify as performance-based
compensation under Code Section 162(m), such that a) the issuance is contingent
upon attainment of pre-established performance criteria; or b) restrictions
lapse contingent upon attainment of pre-established performance criteria. The
performance criteria to be used with such grants shall be recurring after-tax
net income and/or cash flow, at the Company and/or subsidiary level, and
earnings per share and/or total shareholder return, at the Company level, as
determined at the sole discretion of the Committee. Performance criteria will be
established by the Committee prior to the beginning of each performance period,
defined as January 1 of each year, or such later date as permitted under the
Code, or applicable regulations. Notwithstanding any other provision of the
Plan, no individual shall receive a grant of Restricted Stock under this Section
6.2 totaling more than 100,000 shares of Common Stock in any single calendar
year. Recurring after-tax net income means after-tax net income subject to
adjustment by the Committee in its sole discretion for what the Committee
considers an unordinary or nonrecurring items of after-tax net income.

     6.3  Restricted Stock Agreement. Each Restricted Stock Agreement shall be
in such form, and shall set forth the terms, conditions and restrictions of the
Restricted Stock, not inconsistent with the provisions of this

                                       A-5
<PAGE>   36

Plan, as the Administrator shall, from time to time, deem desirable. Each
Restricted Stock Agreement may be different from each other Restricted Stock
Agreement.

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

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

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

     6.7  Nonassignability of Rights. No Participant's right to acquire shares
of Restricted Stock shall be assignable or transferable except pursuant to the
provisions of Section 11.1 of this Plan.

                                   ARTICLE 7

                           ADMINISTRATION OF THE PLAN

     7.1  Administrator. Authority to control and manage the operation and
administration of the Plan shall be vested in the Committee consisting of two
(2) or more members of the Board who are "Non-Employee Directors" within the
meaning of Rule 16b-3 under the Securities Exchange Act of 1934 and are "outside
directors" as referenced in Regulation 1.162-27(e)(3) issued under the Code (the
"Committee" or "Administrator"). Members of the Committee may be appointed from
time to time by, and shall serve at the pleasure of, the Board.

     7.2  Powers of the Administrator. In addition to any other powers or
authority conferred upon the Administrator elsewhere in the Plan or by law, the
Administrator shall have full power and authority: (a) to determine the persons
to whom, and the time or times at which, Incentive Options or Nonqualified
Options and grants of Restricted Stock shall be granted, the number of shares to
be represented by each Option and grant of Restricted Stock and the
consideration, if any, to be received by the Company upon the exercise thereof;
(b) to construe and interpret provisions of the Plan and other documents and
agreements pertaining to the Plan; (c) to create, amend or rescind rules and
regulations relating to the Plan; (d) to determine the terms, conditions and
restrictions contained in, and the form of, Option Agreements and Restricted
Stock Agreements; (e) to determine the identity or capacity of any persons who
may be entitled to exercise a Participant's rights under any Option or
Restricted Stock Agreement granted under the Plan; (f) to correct any defect or
supply any omission or reconcile any inconsistency in the Plan or in any Option
Agreement or Restricted Stock Agreement; (g) to accelerate the vesting of any
Option or grant of Restricted Stock; (h) to extend the exercise date of any
Option and vesting date of any grant of Restricted Stock; (i) except for
changing the Exercise Price of a granted Option, to amend outstanding Option
Agreements and Restricted
                                       A-6
<PAGE>   37

Stock Agreements to provide for, among other things, any change or modification
which the Administrator could have provided for upon the grant of an Option or
Restricted Stock or in furtherance of the powers provided for herein; and (j) to
make all other determinations necessary or advisable for the administration of
the Plan, but only to the extent not contrary to the express provisions of the
Plan. Any action, decision, interpretation or determination made in good faith
by the Administrator in the exercise of its authority conferred upon it under
the Plan shall be final and binding on the Company and all Participants.

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

                                   ARTICLE 8

                               CHANGE IN CONTROL

     8.1  Change in Control of Enron Corp. If at any time after the date the
Plan is adopted when Enron Corp. directly or indirectly owns thirty percent
(30%) or more of the capital stock of the Company, a transaction occurs which is
not approved, recommended or supported by a majority of the board of directors
of Enron Corp. in actions taken prior to, and with respect to, such transaction
in which:

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

          (ii) Enron Corp. sells all or substantially all of its assets to any
     other person or entity,

          (iii) Enron Corp. is dissolved,

          (iv) any third person or entity (other than the trustee or committee
     of any qualified employee benefit plan of Enron Corp.), together with its
     Affiliates and Associates, shall be, directly or indirectly, the Beneficial
     Owner of at least thirty percent (30%) of the outstanding capital stock of
     Enron Corp., or

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

then within (a) ten days of the approval by the stockholders of Enron Corp. of
such merger, consolidation, sale of assets or dissolution as described in clause
(i), (ii) or (iii) of this Section 8.1, or (b) thirty (30) days of the
occurrence of such change of Beneficial Ownership or Directors as described in
clause (iv) or (v) of this Section 8.1, with respect to outstanding grants of
Restricted Stock made under Article 6, all such grants of Restricted Stock,
irrespective of whether they are then vested, shall be surrendered to the
Company by each grantee thereof and such grants shall thereupon be canceled by
the Company, and the grantee shall receive a cash payment by the Company in an
amount equal to the number of Shares subject to the grant of Restricted Stock
held by such grantee multiplied by the Fair Market Value of a Share on the date
determined by the Administrator (as constituted prior to any change described in
clause (iv) or (v)) to be the date of cancellation and surrender of such Options
if any such change of Beneficial Ownership or Directors occurs other than
pursuant to a tender or exchange offer, whichever is appropriate, and with
respect to outstanding grants of Options made under Article 5, all such
outstanding Options irrespective of whether they are then exercisable, shall be
surrendered (at such time as may be necessary to comply with Rule 16b-3 under
the
                                       A-7
<PAGE>   38

Securities Exchange Act of 1934, as amended, if applicable) to the Company by
each grantee thereof and such Options shall thereupon be cancelled by the
Company, and the grantee shall receive a cash payment by the Company in an
amount equal to the number of Shares subject to the Options held by such grantee
multiplied by the difference between (x) and (y) where (y) equals the purchase
price per Share covered by the Option, and (x) equals the Fair Market Value of a
Share on the date determined by the Administrator (as constituted prior to any
change described in clause (iv) or (v)) to be the date of cancellation and
surrender of such Options if any such change of Beneficial Ownership or
directors occurs other than pursuant to a tender or exchange offer, whichever is
appropriate.

     8.2  Change in Control of the Company. If a transaction occurs after the
date the Plan is adopted in which as a result of a transaction that has not been
approved, recommended or supported by a majority of the board of directors of
the Company in actions taken prior to, and with respect to, such transaction:

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

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

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

                                   ARTICLE 9

                     AMENDMENT AND TERMINATION OF THE PLAN

     9.1  Amendments. The Board in its discretion may terminate the Plan at any
time with respect to any shares of Common Stock for which a grant has not
theretofore been made. The Board shall have the right to alter or amend the Plan
or any part thereof from time to time; provided, that no change in any grant
theretofore made may be made which would impair the rights of the recipient of a
grant without the consent of such recipient; and provided further, that
notwithstanding any other provision of the Plan or any grant agreement, without
the approval of the stockholders of the Company no such amendment or alteration
shall be made that would:

          (i) increase the total number of shares of Common Stock available for
     grants under the Plan, except as provided in Article 4 hereof;

          (ii) change the minimum exercise price for grant of Options;

          (iii) extend the maximum period during which grants may be made under
     the Plan; or

          (iv) increase the maximum number of shares of Common Stock for which
     Options may be granted under Section 5.1 or shares of performance-based
     Restricted Stock that may be granted under Section 6.2 to any individual in
     any calendar year.

     The Board may alter or amend the Plan to comply with requirements under the
Code relating to Incentive Options or other types of options which give
Optionees more favorable tax treatment than that applicable to Options granted
under this Plan as of its Effective Date. Upon any such alteration or amendment,
any outstanding Option granted hereunder may, if the Administrator so determines
and if permitted by applicable law, be subject to the more favorable tax
treatment afforded to an Optionee pursuant to such terms and conditions.

     9.2  Plan Termination. Unless the Plan shall theretofore have been
terminated, the Plan shall terminate on February 1, 2009 and no Options or
grants of Restricted Stock may be granted under the Plan thereafter, but Option
Agreements and Restricted Stock Agreements then outstanding shall continue in
effect in accordance with their respective terms and provisions.

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

                                   ARTICLE 10

                                TAX WITHHOLDING

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

                                 MISCELLANEOUS

     11.1  Benefits Not Alienable. No grant of an Option or Restricted Stock and
no right under any such grant shall be assignable, alienable, saleable or
transferable by a Participant other than:

          (a) by will or by the laws of descent and distribution;

          (b) pursuant to a "domestic relations order" as defined in Section 414
              of the Code or Section 206 of the Employee Retirement Income
              Security Act of 1974, as amended;

          (c) by transfer by an eligible Participant, subject to such rules as
              the Committee may adopt to preserve the purposes of the Plan
              (including limiting such transfer to Participants who are
              directors or senior executives), to:

           (I)    a member of his or her Immediate Family,

           (II)   a trust solely for the benefit of the Participant and his or
                  her immediate Family, or

           (III)  a partnership or limited liability company whose only partners
                  or shareholders are the Participant and his or her Immediate
                  Family members,

          (d) by designation, in a manner established by the Committee, of a
              beneficiary or beneficiaries to exercise the rights of the
              Participant and to receive any property distributable with respect
              to any grant upon the death of the Participant.

          Each transferee described in (b) and (c) above is hereafter referred
     to as a "Permitted Transferee", provided that the Committee is notified in
     writing of the terms and conditions of any transfer intended to be
     described in (b) or (c) and the Committee determines that the transfer
     complies with the requirements of the Plan and the applicable grant
     agreement. Any purported assignment, alienation, pledge, attachment, sale,
     transfer or encumbrance that does not qualify under (a), (b), (c) or (d)
     shall be void and unenforceable against the Company. "Immediate Family"
     means, with respect to a particular Participant, the Participant's spouse,
     children or grandchildren (including adopted and stepchildren).

     The terms and provisions of Option Agreements and Restricted Stock
Agreements shall be binding upon the beneficiaries, executors and administrators
of the Participant and on the Permitted Transferees of the Participant
(including the beneficiaries, executors and administrators of the Permitted
Transferees), except that Permitted Transferees shall not reassign any such

                APPROVED SHARE OPTION SCHEME FOR UK PARTICIPANTS

     12.1  Purpose. The purpose of these additional sections is to obtain
Approved Share Option Scheme status for UK Participants under the Plan. These
sections are to be read as a continuation of the Plan and modify the Options
granted thereunder only in relation to UK resident Participants who are granted
Options under the Plan with additional sections. They do not add to or modify
the Plan in respect of any other category of Participant.

     12.2  Additional Definitions. The following additional capitalized
definitions shall have the respective meanings set forth below:

          (a) "Act" shall mean the Income and Corporation Taxes Act 1988.

          (b) "Approved Option" shall mean an Option granted under the Plan with

     sections is approved by the UK Inland Revenue under the Act.

          (c) "Limit" shall mean the greater of

             (i) L100,000 or

             (ii) if there were Relevant Emoluments for the preceding Year of
        Assessment, four times the amount of the Relevant Emoluments for the
        current or preceding Year of Assessment (whichever of those years gives
        the greater amount) or

             (iii) if there were no Relevant Emoluments for the preceding Year
        of Assessment, four times the amount of the Relevant Emoluments for the
        period of 12 months beginning with the first day during the current Year
        of Assessment in respect of which there are Relevant Emoluments.

          (d) "Relevant Emoluments" shall mean such of the emoluments of the UK
     Participant as are liable to be paid under deduction of PAYE income tax.

          (f) "Year of Assessment" shall mean a year beginning on any 6th of
     April and ending on the following 5th of April.

     12.3  Modified Definitions. The following definitions in Article 2 of the
Plan shall be modified as set forth below in relation to Approved Options only
and shall be so construed throughout the Plan:

          (a) "Affiliate" shall mean any company which is both a Subsidiary of
     the Company (as defined by Section 736 of the Companies Act 1985) and under
     the Control of the Company (as defined by Section 840 of the Act) and which
     is for the time being designated by the Committee as a participating

          (c) "Common Stock" shall mean shares of Common Stock of the Company
     which satisfy the provisions of paragraph 10 to 14 inclusive of Schedule 9
     to the Act.

     12.4  Omitted Definitions. The following definitions in Article 2 shall be
treated as having been omitted therefrom in relation to Approved Options only
and the Plan shall accordingly be constructed throughout as if all references to
such definitions had been omitted:

          (i) "Incentive Option" and "Incentive Option Agreement".

          (ii) "Restricted Stock" and "Restricted Stock Agreement".

                                      A-11
<PAGE>   42

     12.5  Nonapplicable Sections. Sections 4.3 and 4.4 shall not apply to
Approved Options.

     12.6  Variation of Share Capital. In the event of any variation of the
share capital of the Company by way of capitalization or rights issue,
consolidation, subdivision or reduction of capital or otherwise, the number of
Shares subject to any Approved Option and the Exercise Price for each of those
Shares shall be adjusted in such manner as the Committee decide to be fair and
reasonable provided that:

          (i) the aggregate amount payable on the exercise of an Approved Option
     in full is not increased

          (ii) the Exercise Price for a Share is not reduced below its par value

          (iii) no adjustment shall be made without the prior approval of the
     Board of Inland Revenue and

          (iv) following the adjustment the Shares continue to satisfy the
     conditions specified in paragraphs 10 to 14 inclusive of Schedule 9 to the
     Act.

     12.7  Eligibility. Article 3 shall be modified in relation to Approved
Options so that:

          (a) only Directors of the Company or a participating Affiliate who are
     required to devote substantially the whole of their time to their duties
     and in any case not less than 25 hours per week (excluding meal breaks),
     and

          (b) Employees who are not Directors of the Company or a participating
     Affiliate who are required to devote substantially the whole of their time
     to their duties and in any case not less than 20 hours per week (excluding
     meal breaks) who are not ineligible to participate in the Plan by virtue of
     paragraph 8 of Schedule 9 to the Act (material interest in a close company)
     shall be eligible to be designated a Participant.

     12.8  Grants of Options.

          A. Exercise Price. The provisions of Section 5.1(i) of the Plan shall
     be modified in relation to Approved Options as if the words: "shall be
     specified in the Award Agreement and" had been included immediately after
     the word "Option" in line 1 thereof.

          B. Time and Method of Exercise. Section 5.1(ii) of the Plan shall be
     modified in relation to Approved Options so that an Option may only be
     exercised by a Participant giving notice to the Company in writing of the
     number of Shares in respect of which he wishes to exercise the Option
     accompanied by the appropriate payment either in cash or by the delivery of
     irrevocable instructions to a broker to deliver promptly to the Company an
     amount equal to the relevant exercise price. No Approved Option may be
     exercised by a UK Participant who has become ineligible to participate in
     the Plan by virtue of paragraph 8 of Schedule 9 to the Act (material
     interest in a close company).

     12.9  Restricted Stock. The provisions of Article 6 of the Plan shall not
apply to Approved Options.

     12.10  General.

          A. Further Limitations on the Amount of Awards. No Approved Options
     shall be granted to UK Participants if at the relevant date of grant the
     aggregate Exercise Price of all subsisting Approved Options granted under
     the Plan and any other plan established by the Company or any associated
     company of the Company and approved by the Inland Revenue under the
     provisions of Schedule 9 to the Act (other than a savings-related share
     option scheme) would exceed the Limit.

          B. Limits on Transfer of Awards. Section 11.1 of the Plan shall be
     modified so that Approved Options will only be exercisable for the period
     of 12 months following the death of the relevant UK Participant. The
     provisions of Section 11.1(b) and Section 11.1(c) shall not apply to
     Approved Options.

          C. Issue or Transfer of Shares. The appropriate number of Shares shall
     be allotted or transferred (as the case may be) within 30 days following
     the exercise of an Option.

     12.11  Amendments to the Plan. No amendments to the Plan which relate to an
Approved Option shall be effective unless they are approved by the UK Inland
Revenue.

shall not apply to Approved Options.
