                                PROXY STATEMENT
 
     The enclosed form of proxy is solicited by the Board of Directors of Enron
Corp. ("Enron") to be used at the 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, May 4, 1999. The mailing
address of the principal executive office of Enron is 1400 Smith St., Houston,
Texas 77002-7369. This proxy statement and the related proxy are to be first
sent or given to the shareholders of Enron on approximately March 30, 1999. Any
shareholder giving a proxy may revoke it at any time provided written notice of
such revocation is received by the Vice President and Secretary of Enron 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.
 
     Holders of record at the close of business on March 8, 1999, of Enron's
Common Stock (the "Common Stock") will be entitled to one vote per share on all
matters submitted to the meeting. Holders of record at the close of business on
March 8, 1999, of Enron's Cumulative Second Preferred Convertible Stock (the
"Preferred Convertible Stock") will be entitled to a number of votes per share
equal to the conversion rate of 13.652 shares of Common Stock for each share of
Preferred Convertible Stock. On March 8, 1999, the record date, there were
outstanding and entitled to vote at the annual meeting of shareholders
351,213,484 shares of Common Stock and 1,315,267 shares of Preferred Convertible
Stock. There are no other voting securities outstanding. Common Stock and
Preferred Convertible Stock are collectively referred to herein as "Voting
Stock."
 
     Enron's annual report to shareholders for the year ended December 31, 1998,
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
 
     At the meeting, sixteen directors are to be elected to hold office until
the next succeeding annual meeting of the shareholders and until their
respective successors have been elected and qualified. All of the nominees are
currently directors of Enron except Dr. John Mendelsohn. Proxies cannot be voted
for a greater number of persons than the number of nominees named on the
enclosed form of proxy. A plurality of the votes cast in person or by proxy by
the holders of Voting Stock is required to elect a director. Accordingly, under
the Oregon Business Corporation Act and Enron's bylaws, abstentions and "broker
non-votes" would not have the same legal effect as a vote withheld with respect
to a particular director. A broker non-vote occurs if a broker or other nominee
does not have discretionary authority and has not received instructions with
respect to a particular item. Shareholders may not cumulate their votes in the
election of directors.
 
     It is the intention of the persons named in the enclosed proxy to vote such
proxy "FOR" the election of the nominees named herein. Should any nominee become
unavailable for election, discretionary authority is conferred to vote for a
substitute. The following information regarding the nominees, their principal
occupations, employment history and directorships in certain companies is as
reported by the respective nominees.

BOARD OF DIRECTORS AND COMMITTEES
 
     The Board of Directors held five regularly scheduled meetings and three
special meetings during the year ended December 31, 1998. The Executive
Committee meets on a less formal basis and may exercise all of the powers of the
Board of Directors, except where restricted by Enron's bylaws or by applicable
law. During the year ended December 31, 1998, the Executive Committee met 13
times. The Executive Committee is currently composed of Messrs. Duncan
(Chairman), Belfer, Foy, Lay, LeMaistre, Skilling and Winokur.
 
     On May 4, 1998, the Board of Directors adopted the Corporate Governance
Guidelines of the Board of Directors of Enron Corp. (the "Corporate Governance
Guidelines"). The Corporate Governance Guidelines set forth procedures and
guidelines to assist the Board of Directors in discharging its responsibilities
to Enron and Enron's shareholders. The Corporate Governance Guidelines impose
the following obligations on the Board of Directors: (i) approval of requirement
of legal and ethical conduct by Enron, its officers, and employees, and (ii)
approval of Enron corporate strategy and major management initiatives including
general oversight of Enron's business. In addition, the Corporate Governance
Guidelines set forth guidelines for selection, compensation and evaluation of
the Board of Directors and senior executives of Enron, and require a succession
plan with respect to senior executives.
 
     The Board of Directors uses working committees with functional
responsibility in the more complex recurring areas where disinterested oversight
is required. The Audit and Compliance Committee serves as the overseer of
Enron's financial reporting, internal controls, and compliance processes. At
five meetings during the year ended December 31, 1998, the Audit and Compliance
Committee met with the independent auditors, as well as Enron officers and
employees who are responsible for legal, financial and accounting matters. In
addition to recommending the appointment of the independent auditors to the
Board of Directors, the Audit and Compliance Committee reviews the scope of and
fees related to the audit, the accounting policies and reporting practices,
contract and internal auditing and internal controls, compliance with Enron's
policies regarding business conduct and other matters as deemed appropriate. The
Audit and Compliance Committee is currently composed of Messrs. Jaedicke
(Chairman), Chan, Foy, and Wakeham and Dr. Gramm.
 
     The Compensation and Management Development Committee's responsibility is
to establish Enron's compensation strategy and ensure that the senior executives
of Enron and its wholly owned affiliates are compensated effectively in a manner
consistent with the stated compensation strategy of Enron, internal equity
considerations, competitive practices and the requirements of appropriate
regulatory bodies. In meeting seven times during the year ended December 31,
1998, the Compensation and Management Development Committee also continued to
monitor and approve awards earned pursuant to Enron's comprehensive executive
compensation program, monitor Enron's employee benefit programs, and review
matters relating to management development and management succession. The
Compensation and Management Development Committee is currently composed of
Messrs. LeMaistre (Chairman), Blake, Duncan and Jaedicke.

     The Finance Committee serves as a monitor of Enron's financial activities.
In meeting seven times during the year ended December 31, 1998, the Finance
Committee reviewed the financial plans and proposals of management, including
equity and debt offerings, changes in stock dividends and the equity repurchase
program, changes in the risk management policy, transaction approval process and
the policy for approval of guarantees, letters of credit, letters of indemnity
and recommending action with regard thereto to the Board of Directors. The
Finance Committee is currently composed of Messrs. Winokur (Chairman), Belfer,
Blake, Chan, Meyer, Urquhart and Walker.
 
     The Nominating and Corporate Governance Committee has oversight for
recommendations regarding the size of the Board of Directors, recruiting and
recommending candidates for election to the Board of Directors, monitoring the
Corporate Governance Guidelines for revision and compliance, and periodic
evaluation of director independence and performance. This committee met three
times during the year ended December 31, 1998. The Nominating and Corporate
Governance Committee is currently composed of Messrs. Walker (Chairman), Meyer
and Wakeham, and Dr. Gramm.

                COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS
 
DIRECTOR COMPENSATION
 
     Each nonemployee director of Enron receives an annual service fee of
$50,000 for serving as a director. No additional fees are paid for serving on
committees, except that committee chairs receive an additional $10,000 annually.
Meeting fees are $1,250 for each Board of Directors meeting attended and $1,250
for each committee meeting attended. Total directors' fees paid in cash,
deferred under the Enron Corp. 1994 Deferral Plan (the "1994 Deferral Plan") or
received in a combination of phantom stock units and stock options in lieu of
cash under the 1991 Stock Plan, as amended and restated effective May 6, 1997,
("the 1991 Stock Plan") in 1998 were $889,000, or an average of $63,500 per
nonemployee director.
 
     Section 6.9 of the 1991 Stock Plan permits nonemployee directors whose
ownership of Common Stock would result in a material conflict of interest for
business, employment or professional purposes, to submit an opinion of counsel
of such fact to the Committee with a request that such nonemployee director not
be eligible to receive further grants under the 1991 Stock Plan and to forfeit
all outstanding grants made to such nonemployee director until such time as the
Committee is satisfied that such conflicts have been removed or no longer apply.
In December, 1998, an opinion of counsel was submitted to the Committee
indicating that Dr. Wendy Gramm, wife of Senator Phil Gramm, could have a
material conflict of interest as a result of legislation that has been, or may
be, introduced in the United States Senate involving electricity deregulation
and other issues of direct concern to Enron and its subsidiaries if she
continued participation in the 1991 Stock Plan and maintained ownership of Enron
stock. Based on the opinion that her continued participation in the 1991 Stock
Plan could be considered as a conflict of interest, Dr. Gramm's unvested
restricted shares and options were canceled as of December 31, 1998, in
accordance with the 1991 Stock Plan. As a result, Dr. Gramm will receive an
additional service fee of $7,323 each quarter for 16 quarters following the date
unvested restricted shares and options were cancelled. In lieu of future stock
grants, Dr. Gramm will receive value equal to the stock grants stipulated under
the 1991 Stock Plan which will be deposited in the Flexible Deferral Account of
the 1994 Deferral Plan coincident with the grant date applicable to the stock
grants stipulated under the 1991 Stock Plan. Additionally, all quarterly
retainer fees and meeting fees will be paid in cash. Further, Dr. Gramm's
phantom stock account in the 1994 Deferral Plan has been reinvested in the
Flexible Deferral Account of the 1994 Deferral Plan effective January 1, 1999.
 
     Directors can elect to receive fees in cash, defer receipt of their fees to
a later specified date under Enron's 1994 Deferral Plan, or receive their fees
in a combination of phantom stock units and stock options in lieu of cash under
the 1991 Stock Plan. Participants in Enron's 1994 Deferral Plan may elect to
invest their deferrals among several different investment choices. During 1998,
six directors elected to defer fees under Enron's 1994 Deferral Plan. Prior to
1994, directors were able to defer their fees under Enron's 1985 Deferral Plan,
which continues to credit interest on account balances based on 150% of Moody's
seasoned corporate bond yield index with a minimum rate of 12%, which for 1996,
1997 and 1998 was the minimum rate of 12%. Three directors elected to receive
their fees in a combination of phantom stock units and stock options in lieu of
cash according to the terms of the 1991 Stock Plan. During 1998, each
nonemployee director received 400 shares of phantom stock units (valued at $53
per share on the date of grant) and options to purchase 1,600 shares (with an
exercise price of $53 per share) according to the terms of the 1991 Stock Plan.

       REPORT FROM THE COMPENSATION AND MANAGEMENT DEVELOPMENT COMMITTEE
                        REGARDING EXECUTIVE COMPENSATION
 
     The Compensation and Management Development Committee (the "Committee") of
the Board of Directors is responsible for developing the Enron executive
compensation philosophy. It is the duty of the Committee to administer the
philosophy and its relationship with the compensation paid to the Chief
Executive Officer (the "CEO") and each of the other executive officers.
 
     The basic philosophy behind executive compensation at Enron is to reward
the executive's performance that creates long-term shareholder value. This
pay-for-performance tenet is embedded in most aspects of an executive's total
compensation package. Salary increases, annual incentive awards and long-term
incentive grants are reviewed periodically to ensure consistency with Enron's
total compensation philosophy.
 
Base Salary
 
     All decisions regarding base salary are made based upon individual
performance as measured against pre-established individual objectives and
competitive practice as measured by periodic compensation surveys.
 
     In the past, Enron has conducted a bi-annual executive compensation study
covering the top 25 to 30 executive positions in the top corporate and operating
company positions. In October, 1998, the Committee utilized the services of
Towers Perrin, a consulting firm experienced in executive compensation, to
conduct an expanded executive compensation study covering the top executives who
have received long-term compensation grants. Corporate positions were
benchmarked using the companies from a variety of industries with revenues from
$20 billion to $30 billion because the Committee felt that this provided more
comparable data for measuring corporate compensation. Operating company
positions were benchmarked according to revenue size using data collected from
sources best representing their specific markets. For example, Enron Capital &
Trade Resources Corp.'s ("ECT") positions were benchmarked with financial
institutions, brokerage firms, and energy marketing and trading firms while
Enron International Inc.("EI") was benchmarked with pipeline companies, business
development and engineering and construction firms with an international focus,
and various financial institutions to represent EI's expertise at obtaining
project financing. Base salaries for all positions are targeted at the median of
the respective markets.
 
Annual Incentive Awards
 
     In 1999, the Annual Incentive Plan will be provided for certain executive
officers subject to the provisions of Section 16 of the Securities Exchange Act
of 1934, as amended ("Section 16 officers"), and will be funded as a percentage
of recurring after-tax net income as approved by the Committee and the
shareholders and is based on company performance and competitive industry
practice. Downward adjustment of the fund is at the sole discretion of the
Committee and is based on performance against other goals such as earnings per
share, cash flow, strengthening the balance sheet and total shareholder return.
These factors are not weighted, but are applied at the sole discretion of the
Committee. However, upward adjustment of the fund, over the formula-driven
amount, is not allowed. Since the performance goal of Enron is recurring
after-tax net income, the fund increases or decreases based on the earnings
performance of Enron. All decisions regarding individual incentive awards are
made based upon individual performance as measured against pre-established
individual objectives and competitive practice as measured by compensation
surveys, but in no event will an individual incentive award exceed the specified
percentage of recurring after-tax net income as established by the Committee and
approved by shareholders. Under the Annual Incentive Plan, awards can be made in
any combination of cash, stock and stock options. Annual incentive awards are
intended to result in total cash compensation (base salary plus annual
incentive) at the top quartile of the industry comparator group, given
 
                                       13
<PAGE>   16
 
top quartile performance. Based upon Enron's 1998 performance and the last
compensation survey described above, this objective was met.
 
Long-Term Incentive Grants
 
     Long-term incentive grants are targeted at the top quartile of the specific
industry comparator group for corporate and operating company executive
compensation participants. Long-term grants are typically made up of any
combination of performance units, stock options, and/or performance based
restricted stock. For ECT executives, the long-term component of their total
compensation package is made up of grants of stock options and phantom stock
units. The phantom stock units are granted under the ECT Phantom Stock Unit
Plan.
 
     In the past, Enron has typically granted performance units to corporate and
certain operating company executives which compare Enron's total shareholder
return to peer group performance over a four-year period. Under this program, in
order for top quartile compensation to be realized, the total shareholder return
of Enron must rank at least third among the peer group of 11 companies for the
four-year period. Although Enron's relative performance to its peers is an
important measure, it has become more difficult to identify the most appropriate
peer group for a company with Enron's diversified lines of business. Also, due
to the changes associated with increased merger and acquisition activity, peer
group performance is much more volatile without directly being tied to the
efforts of executive management. Enron's desire is to (a) ensure executive
retention where performance warrants, (b) compensate top executives based on
performance relative to the aggressive performance goals set at the beginning of
each year and which the company's executives directly control, and (c) provide
long-term compensation programs most effective in creating a link between
executive and shareholder financial returns. As a result, for the 1999 long-term
grants to corporate and certain operating company executives, performance based
restricted stock and stock options have been utilized. Aggregate stock holdings
of the executives have no bearing on the size of long-term incentive grants. The
ultimate value of the performance based restricted stock awards to executives
depends upon the achievement of recurring after-tax net income targets
established by the Committee for the years 1999, 2000 and 2001 and Enron's stock
price. Stock options are granted at market price; therefore, for any
compensation to be realized pursuant to stock options, the market price of
Common Stock must increase.
 
Total Compensation
 
     Approximately 75% of the total compensation of Enron's most senior
executives is "at risk", based strictly upon the performance of Enron relative
to stated recurring after-tax net income targets, stock price performance and
total shareholder return which impacts grants of performance units which are
still outstanding. Also, several significant elements in the employee benefit
package, the Enron Corp. Employee Stock Ownership Plan, Enron Corp. Savings Plan
and Portland General Holdings Retirement Savings Plan (which together hold
approximately 5.9% of Common Stock as of December 31, 1998), the Bonus Stock
Option and Phantom Stock Deferral Programs and the All-Employee Stock Option
Program ("AESOP"), are driven by increasing shareholder value.
 
     Inherent in this "at-risk" component is a heavy weighting toward long-term
performance. We believe this feature provides Enron management with a long-term
strategic incentive that will encourage the continued creation of shareholder
value. In addition, the Committee has approved stock ownership guidelines which
provide that each member of the Office of the Chairman is required to own Enron
stock having a value equal to at least five times his or her annual base salary,
each Management Committee member is required to own Enron stock having a value
equal to at least two times his or her annual base salary, and other principal
 
                                       14
<PAGE>   17
 
corporate and operating officers named in the annual report to shareholders are
required to own Enron stock having a value equal to at least 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.
 
     The Committee consults from time to time with Towers Perrin which has
access to national compensation surveys and financial records of Enron. The
Committee reviews all elements of executive compensation to ensure that the
total compensation delivered is reflective of company performance with input on
market competitiveness. The executive compensation program is designed to
provide top quartile compensation for top quartile performance. Through the
Towers Perrin study which was recently conducted, the Committee confirmed that
Enron's total direct compensation levels are competitive with the targeted
objective.
 
Chief Executive Officer Compensation
 
     As part of an annual review, the Committee applies the executive
compensation philosophy to the total compensation package of the CEO and the
other executives. In 1998, Mr. Lay received a $100,000, or 8.3%, increase in
base salary. Mr. Lay's base salary on May 1, 1998 was $1,300,000. Since Mr.
Lay's base salary exceeds $1,000,000, base salary in excess of this amount is
deferred into Enron's 1994 Deferral Plan to preserve tax deductibility under
Section 162(m) of the Internal Revenue Code. (See "Compliance with Internal
Revenue Code Section 162(m)" below.) In recognition of Enron's extremely strong
performance during 1998 relative to recurring after-tax net income, Mr. Lay
received an annual incentive award consisting of $3,150,000 in cash. The
Committee determined the amount of the annual incentive award taking into
consideration the annual performance report presented by management, which
reflected an increase in total recurring net income of 35% from the previous
year, Enron's increase in earnings per share of over 14%, and a shareholder
return of 39.6%, compared to 2.9% for Enron's proxy peer group, 28.3% for the
Standard & Poors 500 ("S&P 500") and 18.1% for the Dow Jones Industrial Average.
 
     In addition to the annual incentive award, at the end of 1998, Mr. Lay
received a long-term incentive award consisting of a grant of stock options, at
market value on the date of grant, to acquire 295,325 common shares, and a grant
of 68,057 shares of performance based restricted stock. The performance based
restricted stock will vest and be released on January 31, 2002 as follows: (a)
33 1/3% of the shares will vest and be released if earnings targets are met in
any one year of the three-year period 1999, 2000 and 2001, (b) 66 2/3% of the
shares will vest and be released if earnings targets are met in any two years of
the three-year period 1999, 2000 and 2001, and (c) 100% of the shares will vest
and be released if earnings targets are met in each year of the three-year
period 1999, 2000 and 2001 or cumulatively over the three-year period 1999,
2000, and 2001. Shares of performance based restricted stock which do not become
vested according to the above provisions will be canceled. Also, the accelerated
vesting provisions were triggered on (1) Mr. Lay's February 8, 1994 stock option
award since Enron's 1998 recurring earnings per share goal was met and (2) Mr.
Lay's December, 1996 and January, 1997 grants since Enron's total shareholder
return for 1998 of 39.6% was higher than the 1998 S&P 500 performance.
 
     Mr. Lay did not receive a cash payment under the Performance Unit Plan for
the 1995-1998 performance period. Payments are made under the Performance Unit
Plan only if Enron's total shareholder return ranks at least sixth out of 12
industry peers for the four-year performance period. During the measurement
period from 1995-1998, Enron's return to its shareholders was 98.4% compared
with 128.85% for industry peers, 180.8% for the S&P 500, and 20.5% for 90-day
U.S. Treasury Bills. This performance earned Enron a ranking of seventh and
therefore, the units had no value.

Compliance with Internal Revenue Code Section 162(m)
 
     Section 162(m) of the Internal Revenue Code, as amended ("Section 162(m)"),
generally disallows a tax deduction to public companies for compensation over
$1,000,000 paid to a company's CEO and four other most highly compensated
executive officers, as reported in its proxy statement. Qualifying performance
based compensation is not subject to the deduction limit if certain requirements
are met. Enron has structured the performance based portion of the compensation
for most of its executive officers (which currently consists of stock options
grants, performance based restricted stock grants and annual incentive awards)
in a manner that complies with the statute. The Amended and Restated 1991 Stock
Plan, the Amended and Restated Performance Unit Plan, and the Annual Incentive
Plan were presented to and approved by shareholders at the 1997, 1995 and 1994
Annual Meetings of Shareholders, respectively. The Annual Incentive Plan is
being presented to shareholders for approval in 1999, which is required every
five years under Section 162(m) when no funding formula has been specified. The
recommended changes are to establish a specific funding formula as a percentage
of recurring after-tax net income, to specify Section 16 officers as
participants, and to specify an individual limit for payouts.
 
     Occasionally, Enron may grant restricted stock with time based vesting for
specific reasons which would not qualify as performance based compensation.
Also, the ECT Phantom Stock Unit Plan has not been submitted to shareholders for
approval and therefore does not qualify as performance based compensation under
Section 162(m).
 
Summary
 
     Executive compensation at Enron is taken seriously by the Committee, the
Board of Directors and senior management. The Committee believes that there has
been a strong link between the success of the shareholder and the rewards of the
executives. This success is evidenced by the increase in shareholder value from
1989 to 1998, during which time a shareholder who invested $100 in the Common
Stock would have received $715, or a 715% increase in value, compared to 468%
for the S&P 500 and 319% for industry peers. The Committee believes that with
the present plan designs, management will continue to strive to increase
shareholder value.

COMPARATIVE STOCK PERFORMANCE
 
     As required by applicable rules of the Securities and Exchange Commission
(the "SEC"), the graph below was prepared based upon the following assumptions:
 
        1. $10,000 was invested in Enron Common Stock, the S&P 500, and the peer
           group as referenced below on December 31, 1993.
 
        2. The peer group investments are weighted based on the market
           capitalization of each individual company within the peer group at
           the beginning of each year and the trading activity of the stock of
           each individual company during the year.
 
        3. Dividends are reinvested on the ex-dividend dates.
 
     The companies that comprise Enron's peer group are as follows: BP Amoco
Corporation; British Gas PLC; The Coastal Corporation; Columbia Energy Group;
Consolidated Natural Gas Company; Duke Energy Corporation; Occidental Petroleum
Corporation; El Paso Energy Corporation; Sonat Inc.; Dynegy Inc.; and The
Williams Companies, Inc.
 
     Although this method of calculating shareholder return differs from the
method that Enron uses for purposes of its Performance Unit Plan, it does
display a similar trend.

     On a ten-year basis, $10,000 invested in Common Stock on December 31, 1988
would provide a return to shareholders of 715% through December 31, 1998, as
compared to an investment in the S&P 500, which would yield a return of 468%, or
Enron's peer group which would yield a return of 319% for the same time period.

 (1) Includes perquisites and other personal benefits if value is greater than
     the lesser of $50,000 or 10% of reported salary and bonus. Personal plane
     usage of $116,712, $192,847, and $107,548 has been reported for Mr. Lay in
     1996, 1997 and 1998, respectively. Personal plane usage of $78,759 and
     $62,419 has been reported for Ms. Mark in 1997 and 1998, respectively.
     Also, Enron maintains three deferral plans for key employees under which
     payment of base salary, annual bonus, and long-term incentive awards may be
     deferred to a later specified date. Under the 1985 Deferral Plan, interest
     is credited on amounts deferred based on 150% of Moody's seasoned corporate
     bond yield index with a minimum rate of 12%, which for 1996, 1997 and 1998
     was the minimum rate of 12%. No interest has been reported as Other Annual
     Compensation under the 1985 Deferral Plan for participating Named Officers
     because the crediting rates during 1996, 1997, and 1998, did not exceed
     120% of the long-term Applicable Federal Rate ("AFR") of 14.38% in effect
     at the time the 1985 Deferral Plan was implemented. Beginning January 1,
     1996, the 1994 Deferral Plan credits interest based on fund elections
     chosen by participants. Since earnings on deferred compensation invested in
     third-party investment vehicles, comparable to mutual funds, need not be
     reported, no interest has been reported as Other Annual Compensation under
     the 1994 Deferral Plan during 1996, 1997 and 1998. Other Annual
     Compensation also includes cash perquisite allowances and cash paid for
     benefits lost due to statutory and/or plan earnings limits. Principal and
     accrued interest totaling $955,343 on a personal executive loan extended to
     Ms. Mark during 1997 was forgiven during 1998. In 1999, additional loan
     forgiveness of $700,000 was provided to Ms. Mark associated with a personal
     executive loan made to her during 1998.
 
 (2) The following is the aggregate total number of shares in unreleased
     restricted stock holdings and their value as of December 31, 1998 for each
     of the Named Officers: Mr. Lay, 68,057 shares valued at $3,883,503; Mr.
     Skilling, 206,361 shares valued at $11,775,475; Ms. Mark, 144,979 shares
     valued at $8,272,864; Mr. Sutton, 89,088 shares valued at $5,083,584; and
     Mr. Rice, 108,182 shares valued at $6,173,135. In accordance with the
     provisions of the 1991 Stock Plan, in the event of a "change of control,"
     outstanding grants of restricted stock shall become fully vested. Dividend
     equivalents for all restricted stock awards accrue from date of grant and
     are paid upon vesting.
 
 (3) The amounts shown include the value, as of year-end 1996 and 1998, of
     Common Stock allocated during those years to employees' special subaccounts
     under the Enron Corp. Employee Stock Ownership Plan, and 1998 matching
     contributions on employees' Enron Corp. Savings Plan account. Included in
     1996, 1997 and 1998 for Mr. Lay is $3,775, $4,388, and $5,109,
     respectively, that is
                                              (Notes continue on following page)
 
                                       18

     attributable to term life insurance coverage pursuant to split-dollar life
     insurance arrangements. Also included in 1996, 1997 and 1998 for Mr. Lay is
     $276,490, $275,877, and $280,265, respectively, which represents the
     remainder of the annual premium that was provided in exchange for
     forfeiture by Mr. Lay of post-retirement executive supplemental survivor
     benefits and executive supplemental retirement benefits. Additionally,
     included in 1997 and 1998 for Mr. Lay is $14,999 and $16,170, respectively,
     of imputed income that is attributable to a split-dollar life insurance
     premium of $250,000 (also included) which is paid annually by Enron on a
     life insurance policy already owned by Mr. Lay, with recovery of the cost
     of such premiums upon Mr. Lay's death. Included in 1997 and 1998 for Mr.
     Skilling is a cash payment by Enron of $107,673 and $110,192, respectively,
     attributable to term life insurance coverage pursuant to a split-dollar
     life insurance arrangement with recovery of the cost of such premiums upon
     Mr. Skilling's death. Pursuant to Mr. Rice's employment agreement, he
     received retention payments of $500,000 in August 1996, and $250,000 in
     January 1997.
 
 (4) Represents performance based restricted stock which was granted in lieu of
     performance units for the 1999-2002 performance period. Assuming continuous
     employment with the Company, the award will become vested and will be
     released January 31, 2002 as follows: (a) 33 1/3% of the total number of
     shares granted will vest and be released if earnings targets, as set by the
     Board of Directors at its sole discretion, are met in any one year of the
     three-year period 1999, 2000 and 2001, (b) 66 2/3% of the total number of
     shares granted will vest and be released if earnings targets, as set by the
     Board of Directors at its sole discretion, are met in any two years of the
     three-year period 1999, 2000 and 2001, and (c) 100% of the total number of
     shares granted will vest and be released if earnings targets, as set by the
     Board of Directors at its sole discretion, are met in each of the three
     years or cumulatively over the three-year period 1999, 2000 and 2001.
     Shares of restricted stock which do not become vested according to the
     above provisions will be canceled.
 
 (5) Represents restricted stock awarded to Mr. Skilling on October 13, 1997.
     Restricted stock vested 33 1/3% on October 13, 1998, and the remainder will
     vest on October 13, 1999 and October 13, 2000.
 
 (6) Restricted stock was awarded to Mr. Skilling on January 23, 1996, as a
     result of the termination of the ECT Executive Compensation Plan (the "ECT
     Executive Compensation Plan") and his rights related thereto, became 66.7%
     vested on July 23, 1996, and 100% vested on December 1, 1996.
 
 (7) Restricted stock was awarded to Ms. Mark on January 19, 1998 which was to
     vest 33 1/3% on each January 31 of 1999, 2000 and 2001 with an accelerated
     vesting feature allowing for the vesting and release of 100% of the total
     number of shares if in 1998 Enron's actual recurring diluted earnings per
     share ("EPS") exceeded actual 1997 recurring diluted EPS performance. The
     shares were vested and released on January 31, 1999 as Enron exceeded its
     1997 EPS performance in 1998.
 
 (8) Restricted stock and options were granted to Ms. Mark and Mr. Sutton on
     February 10, 1997 as a buyout of their fixed participation interests in the
     Enron Development Corp. Project Participation Plan (the "Project
     Participation Plan"). The restricted stock was to vest 20% at grant and 20%
     per year on each of the first four anniversaries if EI met its earnings
     targets each year through the year 2000, as stated in the 1997-2001
     five-year plan. In consideration of promotions and contract extensions
     initiated during 1998 for Ms. Mark and Mr. Sutton, the vesting schedule was
     revised such that 60% of the restricted shares granted would vest 50% on
     January 31, 1999 and 50% on January 31, 2000. Ms. Mark's restricted shares
     will continue to vest regardless of EI earnings performance and employment
     status or reason for termination. Mr. Sutton's restricted shares will vest
     contingent upon continued employment. The stock options granted February
     10, 1997, were to vest 20% at grant and 20% on each anniversary date
     thereafter. To provide further consideration for contract extension, the
     vesting was accelerated by 12 months, such that the remaining 60% of the
     options granted would vest 50% on January 1, 1999 and 50% on January 1,
     2000. In the event of termination, for any reason, prior to January 1,
     2000, the unvested options shall become fully vested. In the event of
     termination for any reason, Ms. Mark and Mr. Sutton shall have the lesser
     of three years or the remaining term of the options to exercise their
     options.
 
 (9) Restricted stock and options were granted to Ms. Mark and Mr. Sutton on
     February 12, 1996 for entering into employment agreements and to replace
     variable project participation interests under the Project Participation
     Plan. The restricted shares were to vest conditioned upon meeting certain
     Enron after-tax net income and EI aggregate project net present value
     targets. In consideration of promotions and contract extensions, a revised
     vesting schedule was approved which provides that unvested restricted
     shares would vest 50% on January 31, 1999 and 50% on January 31, 2000 tied
     to EI meeting earnings targets in 1998 and 1999. The stock options were to
     vest 25% at grant and 75% on February 12, 2001 with an acceleration feature
     on the condition that Enron met the EPS targets set by the Board of
     Directors for 1996, 1997 and 1998 with 25% vesting on February 1, 1997,
     February 1, 1998, and February 1, 1999, respectively. In consideration of
     promotions and contract extensions initiated during 1998 for Ms. Mark and
     Mr. Sutton, the vesting schedule was revised such that 50% of the
     restricted shares granted would vest 50% on January 1, 1999 and 50% on
     January 1, 2000 with vesting no longer tied to EPS targets or employment.
     In the event of termination, for any reason, prior to January 1, 2000, the
     unvested options shall become fully vested. In the event of termination for
     any reason, Ms. Mark and Mr. Sutton shall have the lesser of three years or
     the remaining term of the options to exercise their options.

(10) Mr. Rice received a grant of 40,051 restricted shares on August 10, 1998 in
     lieu of cash compensation, which vests based upon the ratio of ECT actual
     earnings to target earnings that are achieved for the year ending on
     December 31, 1998 and each subsequent December 31 ending on or before

     than 95% but less than 105%; 33 1/3% if the ratio is more than 105%, but
     less than 120%; and 40% if the ratio is more than 120%. On January 31,

 (1) The dollar amounts under these columns represent the potential realizable
     value of each grant of options assuming that the market price of Common
     Stock appreciates in value from the date of grant at the 5% and 10% annual
     rates prescribed by the SEC and therefore are not intended to forecast
     possible future appreciation, if any, of the price of Common Stock.
 
 (2) If a "change of control" (as defined in the 1991 Stock Plan) were to occur
     before the options become exercisable and are exercised, the vesting
     described below will be accelerated and all such outstanding options shall
     be surrendered and the optionee shall receive a cash payment by Enron in an
     amount equal to the value of the surrendered options (as defined in the
     1991 Stock Plan).
 
 (3) An appreciation in stock price, which will benefit all shareholders, is
     required for optionees to receive any gain. A stock price appreciation of
     0% would render the option without value to the optionees.
 
 (4) Represents stock options awarded on January 5, 1998, or January 19, 1998.
     Options vested 20% on date of grant, and will vest 20% on each grant date
     anniversary thereafter.
 
 (5) Represents stock options awarded under the Long-Term Incentive Program for
     1999. Stock options awarded on December 31, 1998 vested 25% on the date of
     grant and will vest 25% on each grant date anniversary thereafter.
 
 (6) Represents stock options awarded on May 4, 1998, which vested 33 1/3% on
     January 1, 1999, and will vest 33 1/3% on each grant date anniversary
     thereafter.
 
 (7) Represents stock options awarded on May 4, 1998 for Ms. Mark and June 22,
     1998 for Mr. Sutton, which will vest 33 1/3% on May 4, 1999, and 33 1/3% on
     each grant date anniversary thereafter.
 
 (8) Represents stock options awarded on June 22, 1998, which vested 25% on
     December 31, 1998, and will vest 25% on each December 31 thereafter.
 
 (9) Represents stock options awarded on December 31, 1998, which vest 25% on
     December 31, 1999, and 25% on each grant date anniversary thereafter.
 
(10) Represents 100,000 stock options awarded on August 10, 1998 and 148,775
     stock options awarded on December 31, 1998 which vested 20% on December 31,
     1998 and will vest 20% on each December 31 thereafter.
 
(11) Includes options awarded on December 31, 1998 under the All Employee Stock
     Option Program to employees hired during 1998.
 
(12) Weighted average exercise price of all Enron stock options granted to
     employees in 1998.
 
(13) Appreciation for All Employee and Director Optionees is calculated using
     the maximum allowable option term of ten years, even though in some cases
     the actual option term is less than ten years. Appreciation for all
     shareholders is calculated using an assumed ten-year option term, the
     weighted average exercise price for All Employee and Director Optionees
     ($49.9120) and the number of shares of Common Stock acquired and
     outstanding on December 31, 1998.

(1) Represents performance units awarded under the Performance Unit Plan of
    Enron for the 1998-2001 performance period. Grants were made at the
    beginning of the fiscal year 1998 and each unit was assigned a value of
    $1.00. The units are subject to a four-year performance period, at the end
    of which Enron's total shareholder return is compared to that of the 11 peer
    companies included in the current peer group. At that time, the units are
    assigned a value ranging from $0 to $2.00 based on the rank of Enron's
    shareholder return within the current peer group. To be valued at the
    maximum of $2.00, Enron must rank first, and to be valued at the target of
    $1.00, Enron must rank third. Regardless of Enron's rank, Enron's
    shareholder return must be above the return on 90-day U.S. Treasury Bills
    over the same performance period in order for any value to be assigned.
 
RETIREMENT AND SUPPLEMENTAL BENEFIT PLANS
 
     Enron maintains the Enron Corp. Cash Balance Plan (the "Cash Balance Plan")
which is a noncontributory defined benefit plan to provide retirement income for
employees of Enron and its subsidiaries. Through December 31, 1994, participants
in the Cash Balance Plan with five years or more of service were entitled to
retirement benefits in the form of an annuity based on a formula that uses a
percentage of final average pay and years of service. In 1995, the Board of
Directors adopted an amendment to and restatement of the Cash Balance Plan
changing the plan's name from the Enron Corp. Retirement Plan to the Enron Corp.
Cash Balance Plan. In connection with a change to the retirement benefit
formula, all employees became fully vested in retirement benefits earned through
December 31, 1994. The formula in place prior to January 1, 1995 was suspended
and replaced with a benefit accrual in the form of a cash balance of 5% of
annual base pay beginning January 1, 1996. Under the Cash Balance Plan, each
employee's accrued benefit will be credited with interest based on ten-year
treasury bond yields. Directors who are not employees are not eligible to
participate in the Cash Balance Plan.
 
     Enron also maintains a noncontributory employee stock ownership plan
("ESOP") which covers all eligible employees. Allocations to individual
employees' retirement accounts within the ESOP offset a portion of benefits
earned under the Cash Balance Plan. December 31, 1993 was the final date on
which ESOP allocations were made to employees' retirement accounts.
 
     In addition, Enron has a supplemental retirement plan that is designed to
assure payments to certain employees of that retirement income that would be
provided under the Cash Balance Plan except for the dollar limitation on accrued
benefits imposed by the Internal Revenue Code of 1986, as amended (the "Code")
and a pension program for deferral plan participants that provides supplemental
retirement benefits equal to any reduction in benefits due to deferral of salary
into Enron's Deferral Plans.

     NOTE: The estimated annual benefits payable are based on the straight life
           annuity form without adjustment for any offset applicable to a
           participant's retirement subaccount in the ESOP.
 
     Mr. Skilling participates in the Executive Supplemental Survivor Benefit
Plan (the "Survivor Benefit Plan"). Mr. Lay has waived his participation in lieu
of life insurance premiums. In the event of death after retirement, the Survivor
Benefit Plan provides an annual benefit to the participant's spouse equal to 50%
of the participant's annual base salary at retirement, paid for ten years. The
Survivor Benefit Plan also provides that in the event of death before
retirement, the participant's spouse receive an annual benefit equal to 30% of
the participant's annual base salary at death, paid for the life of the
participant's spouse (but for no more than 20 years in some cases). Mr. Lay has
an agreement which was entered into with Houston Natural Gas Corporation ("HNG")
for an annual benefit equal to 30% of his annual base salary upon death before
retirement, paid for the life of his spouse.
 
SEVERANCE PLANS
 
     Enron's Severance Pay Plan, as amended, provides for the payment of
benefits to employees who are terminated for failing to meet performance
objectives or standards or who are terminated due to reorganization or economic
factors. The amount of benefits payable for performance related terminations is
based on length of service and may not exceed six weeks of pay. For those
terminated as the result of reorganization or economic circumstances, the
benefit is based on length of service and amount of pay up to a maximum payment
of 26 weeks of base pay. If the employee signs a Waiver and Release of Claims
Agreement, the employee may receive an additional severance benefit equal to the
severance benefit described above. Under no circumstances will the total
severance benefit paid under Enron's Severance Pay Plan exceed 52 weeks of pay.
Under Enron's Change of Control Severance Plan, in the event of an unapproved
change of control of Enron, any employee who is involuntarily terminated within
two years following the change of control will be eligible for severance
benefits equal to two weeks of base pay multiplied by the number of full or
partial years of service, plus one month of base pay for each $10,000 (or
portion of $10,000) included in the employee's annual base pay, plus one month
of base pay for each 5% of annual incentive award opportunity under any approved
plan. The maximum an employee can receive is 2.99 times the employee's average
W-2 earnings over the past five years.

                              EMPLOYMENT CONTRACTS
 
     Mr. Lay entered into an employment agreement with Enron in December, 1996,
which provides for a minimum salary effective January 1, 1997, of $1,200,000. To
preserve tax deductibility, any base salary in excess of $1,000,000 must be
deferred into Enron's 1994 Deferral Plan. The agreement provides for a grant of
1,275,000 stock options, 50% granted in December, 1996 and 50% granted in
January, 1997, at market value on each date of grant. The stock options vested
20% on date of grant and will be 100% vested on November 1, 2003. However, the
vesting schedule may be accelerated if Enron's total shareholder return equals
or exceeds 120% of the S&P 500 in calendar years 1997, 1998, and 1999. The
agreement also provides for a split-dollar life insurance arrangement, whereby
Enron will pay five annual premiums of $250,000 on a life insurance policy
already owned by Mr. Lay, with recovery of the cost of such premiums upon Mr.
Lay's death. Benefits payable under Enron's Deferral Plans and the HNG Deferral
Plan in the event of Mr. Lay's termination of employment will be paid as if Mr.
Lay had retired from Enron, regardless of the reason for termination. In
addition, the maturity date on Mr. Lay's $4,000,000 interest bearing line of
credit was extended to December 31, 2001 under the agreement. The highest
outstanding principal balance on the line of credit during 1998 was $2,215,000,
which was repaid on February 25, 1998. Loans totaling $1,775,000 were issued
during the period beginning June 18, 1998 through September 4, 1998. Total
accrued interest on the loan in 1998 was $60,522, calculated at an average
interest rate of 5.44% (representing the mid-term AFR), and such interest has
been repaid by Mr. Lay. In the event of his involuntary termination, Mr. Lay
will receive amounts prescribed in the agreement, offset against amounts payable
under the severance plan maintained by Enron, through the term of the agreement,
which expires on December 31, 2001. If severance remuneration payable under the
agreement is held to constitute an "excess parachute payment" and Mr. Lay
becomes liable for any tax penalties imposed thereon, Enron will make a cash
payment to him in an amount equal to the tax penalties plus an amount equal to
any additional tax for which he will be liable as a result of receipt of the
payment for such tax penalties and payment for such reimbursement for additional
tax. The employment agreement contains noncompete provisions in the event of Mr.
Lay's termination of employment.
 
     Mr. Skilling entered into an employment agreement with Enron in January,
1996, which, as amended, provides for a minimum annual salary of $750,000. In
January, 1997, the agreement was amended to reflect Mr. Skilling's enhanced
duties as President and Chief Operating Officer of Enron. The amended agreement
provides for a revision of the vesting schedule on 500,000 stock options granted
on August 29, 1994, such that one-third of the options will vest on each May 1
in 1997, 1998, and 1999. In the event of his involuntary termination, Mr.
Skilling will receive amounts prescribed in the agreement through the term of
the agreement. In order to tie Mr. Skilling's compensation more closely to Enron
stock performance as opposed to any one Enron operating company, in October,
1997, his contract was renegotiated and extended through December 31, 2001. As a
result, Mr. Skilling received on October 13, 1997, a grant of 972,090 Enron
stock options with standard vesting of 20% at grant and 20% on each of the
following four anniversary dates, a grant of 263,158 shares of restricted stock
to vest 33 1/3% on each of the first three grant date anniversaries and a
$4,000,000 loan to accrue interest at the October, 1997 mid-term AFR of 6.24%
compounded semiannually until maturity date of December 31, 2001. The terms of
the contract specify that if Mr. Skilling fully performs all the duties and
responsibilities expected of him in his position and under his employment
agreement through December 31, 2001, then 50% of the loan amount will be
forgiven and the remaining 50% shall be repaid to Enron by Mr. Skilling. Mr.
Skilling is responsible for 100% of the loan interest. Through September, 1998,
the loan accrued interest totaling $215,664 which has been repaid by Mr.
Skilling. If Mr. Skilling voluntarily terminates employment, or is terminated
for cause prior to December 31, 2001, the entire loan amount and interest is due
and payable. The loan is collateralized with Enron Common Stock, Enron Oil & Gas
Common Stock and 1994 Deferral Plan benefits. As an additional benefit to Mr.
Skilling,
                                       24

Enron has entered into an agreement with Mr. Skilling to provide split-dollar
life insurance whereby Enron will pay a portion of the annual premiums on a life
insurance policy owned by Mr. Skilling, with recovery of the cost of such
premiums upon Mr. Skilling's death. In 1998, the insurance premium paid by Enron
was $110,192 which generates no imputed income as Mr. Skilling contributes an
amount equal to the annual cost of current life insurance as measured by the
insurer's current minimum premium rate for standard risks. The employment
agreement contains noncompete provisions in the event of Mr. Skilling's
termination of employment.
 
     Effective May, 1998, Ms. Mark entered into an employment agreement with
Enron through December 31, 2001 as Chairman of EI and Vice Chairman, Enron. The
employment agreement was further amended when it was assigned to, and assumed by
both Enron and Azurix Corp. ("Azurix") effective February 1, 1999, when Ms. Mark
assumed the role as Chairman and CEO, Azurix, in addition to her
responsibilities as Vice Chairman, Enron. The agreement with Enron and Azurix
provides for an annual salary of not less than $710,000. Under the terms of the
agreement, in May, 1998, Ms. Mark was granted 100,000 Enron stock options that
have a ten-year term and vest 33 1/3% on each of January 1, 1999, January 1,
2000 and January 1, 2001, and 350,000 Enron Corp. stock options which have a
ten-year term that vest 33 1/3% on each of May 4, 1999, May 4, 2000, and May 4,
2001. The agreement also stipulated Ms. Mark's 1998 bonus target to be one
percent of EI's after-tax net income subject to adjustment in the sole
discretion of Enron's Chairman and CEO taking into consideration after-tax net
income and funds flow targets set each year by the Board of Directors, as well
as other performance criteria. The agreement further stipulates that bonus
calculations for 1999 through 2001 will be determined prospectively. Further,
the agreement provides that Ms. Mark is eligible to participate in either the
Enron Corp. executive compensation long-term incentive program or the Azurix
Corp. 1999 Stock Plan. During the term of this agreement, Ms. Mark was granted
2,000,000 Azurix stock options from the Azurix Corp. 1999 Stock Plan, effective
February 2, 1999, which will vest 25% per year over the next four-year period.
The agreement also provides for full vesting of specific grants and awards made
to Ms. Mark under long term incentive plans maintained by Enron in the event of
involuntary termination, death or disability and, as amended in February, 1999,
precludes full vesting of long term grants made under the Azurix Corp. 1999
Stock Plan in the event of involuntary termination or termination. The agreement
as amended provides 100% of base pay and unpaid bonuses through the contract
term in the event of involuntary termination. The employment agreement contains
noncompete provisions in the event of Ms. Mark's termination of employment.
 
     Ms. Mark received a personal executive loan from Enron in the amount of
$900,000 on May 7, 1997. The principal and accrued interest totaling $955,343 on
the outstanding loan as evidenced by a note dated May 7, 1997, was forgiven in
May, 1998 in consideration of Ms. Mark's increased responsibilities. Due to
revised vesting provisions tied to a restricted stock grant made by Enron in
1997, which triggered constructive receipt for income tax purposes, a $2.5
million loan was approved which was collateralized with Enron stock and which
accrues interest compounded semiannually on the unpaid principal and interest of
the loan at the short-term AFR in effect during each month that the loan is
outstanding. Ms. Mark has repaid $550,000 of the principal of this loan, and an
additional $700,000 has been forgiven in consideration for Ms. Mark's
performance in 1998. As per the terms of the loan agreement, the remaining
principal balance of $1.25 million plus 100% of the accrued interest is to be
repaid as of January 31, 2000. Accrued interest through December 31, 1998 was
$84,617.13 which was accrued at an average rate of 5.23% for 1998.
 
     Effective June, 1998, Mr. Sutton entered into an employment agreement with
Enron through June 30, 2003. The agreement provides for an annual salary of not
less than $535,000. Pursuant to the terms of the agreement, Mr. Sutton was
granted 100,000 Enron stock options on June 22, 1998, that have a ten-year term
 
                                       25
<PAGE>   28
 
and that vest 33 1/3% on each of May 4, 1999, May 4, 2000 and May 4, 2001, and
an additional 100,000 Enron stock options on June 22, 1998, that have a ten-year
term and vest 25% on December 31, 1998, December 31, 1999, December 31, 2000 and
December 31, 2001. Mr. Sutton received a grant of 74,390 stock options on
December 31, 1998 and will also receive grants of stock options in years 1999,
2000, and 2001 valued at $1,060,000 which will vest, conditioned on continued
employment, in 25% increments on December 31 of the four years following the
date of grant. Mr. Sutton received a grant of 16,061 shares of restricted stock
on January 31, 1999 and will also receive grants of restricted stock in January
2000, 2001, 2002 and 2003, or in January of a subsequent year but no subsequent
year later than January, 2003, if the following cumulative provisions apply,
each grant having a value of $1,060,000, conditioned upon EI meeting at least
80% of its 1998 after tax net income target; such that the 80% target shall be a
cumulative percentage over a five-year period beginning with 1998 so that if Mr.
Sutton misses a target in any single year, he shall have the ability to receive
such grant in a future year based on a cumulative year average. Such grants of
restricted stock will vest, conditioned on Mr. Sutton's continued employment
with EI, in 25% increments each year beginning on the anniversary date of each
date of grant. Mr. Sutton's agreement further stipulated a 1998 bonus amount
equivalent to .75% of EI's after-tax net income through June 30, 1998, plus a
$500,000 annual bonus target for the last six months of 1998. In addition, the
agreement stipulates that if the Enron Wholesale Group met its financial
targets, Mr. Sutton would be eligible for an additional $300,000 bonus target.
As a result of the increased emphasis on long-term performance and long-term
compensation as part of the total compensation mix, for 1999 forward through the
remainder of the term, Mr. Sutton will have a $500,000 annual bonus target based
on achievement of EI's financial targets plus an additional $300,000 annual
bonus target based on the Enron Wholesale Group meeting its financial targets.
All targets are established by Enron Board of Directors. The agreement provides
125% of base pay through the contract term in the event of involuntary
termination. The employment agreement contains noncompete provisions in the
event of Mr. Sutton's termination of employment.
 
     Effective January 31, 1998, Mr. Rice entered into an employment agreement
with Enron for a three-year term ending January 31, 2001 which provides for an
annual salary of not less than $400,000, as of June 1, 1998. In the employment
agreement, Mr. Rice was granted 100,000 Enron stock options that have a ten-year
term and vests in increments of 20% on December 31 of each of the next five
years, and 40,051 restricted shares that vest based upon the ratio of ECT's
actual earnings to ECT's target earnings achieved for the year ending on
December 31, 1998 and each subsequent December 31 ending on or before December
31, 2002, and will be released on January 31 following the end of the calendar
year as follows: 0% if the earnings ratio is less than 80%; 15% if the ratio is
more than 80% but less than 95%; 20% if the ratio is more than 95% but less than
105%; 33 1/3% if the ratio is more than 105%, but less than 120%; and 40% if the
ratio is more than 120%. On January 31, 1999, 33 1/3% of the shares became
vested and were released. In both 1999 and 2000, Mr. Rice will be granted stock
options having a grant value of $2,120,000 for each year. These options were
granted on December 31, 1998 for 1999 and will be granted on December 31, 1999
for 2000, and shall vest 20% on the date of grant and 20% on December 31 of each
of the next four years following the date of grant. As a result of the increased
emphasis on long-term performance and long-term compensation as part of the
total compensation mix, Mr. Rice shall be eligible for annual bonuses, with an
annual target of $500,000 based on achievement of ECT's financial targets, plus
an additional $300,000 annual bonus target based on Enron Wholesale Group
meeting its financial targets. All targets are established by the Enron Board of
Directors. In the event of Mr. Rice's voluntary or involuntary termination, Mr.
Rice will receive amounts prescribed in the agreement through the term of the
agreement which expires on January 31, 2001. The employment agreement contains
noncompete provisions in the event of Mr. Rice's termination of employment. In
the event of involuntary termination, all grants, excluding the grant made to
Mr. Rice under the All Employee Stock
 
                                       26
<PAGE>   29
 
Option Program, shall continue to vest during the ninety-day period following
the date of Mr. Rice's termination. In the event of involuntary termination, the
terms of Mr. Rice's contract provide for a lump-sum payment of $800,000 in
consideration of non-compete obligations, as well as 100% of base salary through
the term of the agreement. In the event of voluntary termination, the contract
provides a lump-sum payment of $800,000.
 
                              CERTAIN TRANSACTIONS
 
     Effective August 1, 1991, Enron, Enron Power Corp. (a wholly owned
subsidiary of Enron) and John A. Urquhart entered into a Consulting Services
Agreement which has been amended several times, the latest of which amendments
was effective as of December 31, 1998, to provide for an extension of the
agreement through December 31, 1999. Pursuant to the terms of the agreement, Mr.
Urquhart serves as Senior Advisor to the Chairman and consults with Enron
regarding the development and implementation of an integrated strategic
international business plan and other matters concerning international business
and operations. The amendment provides for a retainer fee of $33,075 per month
for providing up to 90 days of consulting services annually and a daily rate of
$4,410 for days in excess of 90 days annually. In August, 1995, the agreement
was amended to provide for a grant of 50,000 Enron phantom stock options at a
grant price equal to the December 29, 1995 Enron closing stock price, or
$38.125. The phantom shares vested 50% on June 29, 1996, and 50% on December 29,
1996, and were to expire on December 31, 1998. With the extension of Mr.
Urquhart's Consulting Services Agreement through December 31, 1999, the
expiration date of the 50,000 Enron phantom stock options granted on December
29, 1995 was extended to December 31, 2000. Mr. Urquhart is reimbursed for all
reasonable out-of-pocket expenses incurred in performing services under the
agreement. The services to be performed by Mr. Urquhart pursuant to the
Consulting Services Agreement do not include, and are in addition to, his duties
as a director of Enron, and the above compensation is in addition to the
remuneration payable to Mr. Urquhart as a member of the Board of Directors of
Enron. During 1998, Enron paid Mr. Urquhart $410,106 for services rendered
(including reimbursement of expenses) under the Consulting Services Agreement.
 
     Mr. Urquhart is a member of the Managing Board of Amoco/Enron Solar
Partnership, Chairman and Chief Executive Officer of Enron Solar Energy Inc. and
a director of Enron Renewable Energy Corp. ("EREC"). On January 2, 1997, Mr.
Urquhart was awarded 67,495 EREC stock options at a grant price of $15.00,
granted in tandem with 23,750 Enron stock options with an exercise price of
$42.625, both of which were awarded at fair market value on the date of grant.
The options became 20% vested on the date of grant and will become 20% vested on
each anniversary of the date of grant through January 2, 2001. The exercise of
either the EREC or Enron options will cancel the tandem options of the other
security. These stock options will expire on January 2, 2007.
 
     Effective September 30, 1996, a monthly retainer of $6,000 was approved for
payment to Lord John Wakeham in consideration of his services to Enron and its
affiliates relating to his advice and counsel on matters relating specifically
to European business and operations. The services to be performed by Lord
Wakeham pursuant to this monthly retainer arrangement do not include, and are in
addition to, his duties as a director of Enron, and the above compensation is in
addition to the remuneration payable to Lord Wakeham as a member of the Board of
Directors of Enron. For the year 1998, Enron paid Lord Wakeham $72,000 for
services rendered to Enron Europe Limited.
 
     Enron Property & Services Corp., a subsidiary of Enron, and Lay/Wittenberg
Travel Agency in the Park, Inc. ("TAP") are parties to an Agreement for Services
under which TAP provides travel arrangements for Enron and its affiliates'
employees. The agreement will expire on March 31, 2001. TAP is owned 50% by
                                       27
<PAGE>   30
 
Sharon Lay, sister of Kenneth L. Lay, Chairman of the Board and Chief Executive
Officer of Enron. During 1998, TAP received gross commissions in the amount of
$2,504,781 attributable to Enron employee travel.
 
     Herbert S. Winokur, Jr., a director of Enron, is an affiliate of National
Tank Company ("NATCO"), a privately owned company that is a provider of wellhead
equipment, systems and services used in the production of oil and gas. During
the calendar years ended December 31, 1997 and 1998, NATCO recorded revenues of
$1,035,000 and $643,793, respectively, from sales to subsidiaries of Enron of
oilfield equipment, services and spare parts in the ordinary course of business
on terms that Enron believes are no less favorable than the terms of similar
arrangements with third parties. Mr. Winokur's affiliation with NATCO arises out
of his indirect management of two funds that own NATCO's indirect parent. In
addition, Mr. Winokur is a minority limited partner of such funds. Enron
believes that its subsidiaries and NATCO will continue to enter into similar
arrangements throughout 1999.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Until April 1986, Mr. Belfer was an officer of Belco Petroleum Corporation,
a wholly owned subsidiary of Enron. During 1996, Belco Oil & Gas Corp. ("BOGC")
entered into natural gas and crude oil commodity swap agreements and option
agreements with ECT. BOGC is a publicly traded corporation, approximately 77% of
the outstanding common stock of which is owned by Mr. Belfer and members of his
family. These agreements were entered into in the ordinary course of business of
ECT and are on terms that ECT believes are no less favorable than the terms of
similar arrangements with third parties. Pursuant to the terms of these
agreements, Enron received from BOGC a net amount of approximately $1,682,110 in
1998. The amount of future payments (as well as whether payments are made by ECT
to BOGC or vice versa) is affected by fluctuations in energy commodity prices.
Enron believes that BOGC and ECT will continue to enter into similar
arrangements throughout 1999.
 
     Enron retains the law firm of Bracewell & Patterson L.L.P. for certain
legal services. During the last fiscal year, Enron and its subsidiaries paid
Bracewell & Patterson L.L.P., from which Mr. Foy is a retired partner, legal
fees which Enron believes to be reasonable for the services rendered. Until
1979, Mr. Foy was President of HNG, a predecessor of Enron.
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires Enron's officers, directors and persons who own more
than 10% of the Common Stock or the Preferred Convertible Stock to file reports
of ownership and changes in ownership concerning the Common Stock or the
Preferred Convertible Stock with the SEC and to furnish Enron with copies of all
Section 16(a) forms they file. Based upon Enron's review of the Section 16(a)
filings that have been received by Enron, Enron believes that all filings
required to be made under Section 16(a) during 1998 were timely made, except
that Lawrence Ruben did not timely file two reports relating to a total of six
transactions and Kenneth D. Rice did not timely file his Initial Statement of
Beneficial Ownership.

               APPROVAL OF THE ENRON CORP. ANNUAL INCENTIVE PLAN
 
     Enron currently maintains the Enron Corp. Annual Incentive Plan (the
"Annual Incentive Plan") for all full-time and part-time employees, which is
designed to recognize, motivate and reward exceptional accomplishment toward
annual corporation objectives; to attract and retain quality employees; and to
be market competitive. The following summary description of a new Annual
Incentive Plan is qualified in its entirety by reference to the full text of the
Annual Incentive Plan which is attached to this proxy statement as Exhibit A.
 
     Only employees who are officers of Enron subject to the short-swing profit
provisions of Section 16 of the Exchange Act are eligible to receive awards
under the new Annual Incentive Plan, which will be administered by the
Committee. An award fund, five percent of recurring after-tax net income of
Enron, has been established and recommended for approval by shareholders.
Depending on facts and circumstances, the Committee has the discretion to reduce
the amount of an award fund previously established. The Committee may not
increase the amount of the award fund.
 
     The maximum amount of compensation that can be paid to any individual for a
calendar year is one percent (1%) of the recurring after-tax net income of Enron
for any calendar year.
 
     Awards payable under the Annual Incentive Plan will be paid from the
general assets of Enron. No fund or trust is established or maintained under the
Annual Incentive Plan for the payment of such awards. Enron may elect to pay
awards in cash or other property having equivalent value, including shares of
Common Stock.
 
     The Committee may modify or terminate the Annual Incentive Plan at any time
without prior notice to or consent of participants; provided that, without the
approval of the shareholders of Enron, no such amendment shall be made that
would change the class of participants eligible to receive awards under the
Annual Incentive Plan, fund total payouts at a level greater than five percent
(5%) of recurring after-tax net income, base the award fund on a performance
measure other than recurring after-tax net income, increase the maximum
individual target award level under the Annual Incentive Plan or modify any
other material terms of the Annual Incentive Plan.
 
     Shareholder approval is required if payments from the Annual Incentive Plan
are to be tax deductible as performance-based compensation under Section 162(m),
enacted in 1993. Section 162(m) generally disallows a tax deduction for
compensation over $1 million paid to a Named Officer, unless it qualifies as
performance-based. In the event shareholders do not approve the new Annual
Incentive Plan attached as Exhibit A, it will not become effective.
 
AMOUNTS GRANTED UNDER THE PLAN FOR 1998
 
     The benefits to be received for 1999 performance under the Annual Incentive
Plan are not determinable, since funding will be based on 1999 recurring
after-tax net income. However, set forth below are the amounts that would have
been paid for 1998 performance if the Annual Incentive Plan, as proposed to be
adopted by
 
                                       29
<PAGE>   32
 
the shareholders, had been in effect. The maximum payout that could have been
paid to any individual, based on .5% of 1998 recurring after-tax net income, was
$3,485,000.

                                    ITEM 3.
 
                APPROVAL OF AMENDED AND RESTATED 1991 STOCK PLAN
 
     The shareholders approved the Enron Corp. 1991 Stock Plan (the "1991 Stock
Plan") at the 1991 Annual Meeting, approved an amendment to the 1991 Stock Plan,
effective May 3, 1994, at the 1994 Annual Meeting and approved an amended and
restated 1991 Stock Plan, effective May 6, 1997, at the 1997 Annual Meeting. The
1991 Stock Plan is intended to provide individual participants with an
opportunity to acquire a proprietary interest in Enron and give them an
additional incentive to use their best efforts for Enron's long-term success.
The 1991 Stock Plan permits the granting of (i) stock options, including
incentive stock options meeting the requirement of the Code, (ii) stock
appreciation rights ("SARs"), (iii) phantom stock units and (iv) restricted
stock, any of which may be granted separately or together. Grants may be made to
any employee or officer of Enron or any of its affiliates, nonemployee directors
and nonemployee contractors performing services for Enron or any of its
affiliates. The 1991 Stock Plan is administered by the Compensation and
Management Development Committee of the Board of Directors (the "Committee"),
each of the members of which meet the definition of nonemployee director in Rule
16b-3 under the Exchange Act. The Committee has the authority to establish
administrative rules, to designate individuals to receive awards and the size of
such awards, and to set the terms and conditions of awards.
 
     Stock options permit the recipient to purchase shares of Common Stock,
commonly referred to as exercising their option, at a fixed price, determined on
the date of grant, regardless of the fair market value on the date of exercise.
The holder of a SAR is entitled to receive the excess of the fair market value
on the date
 
                                       30
<PAGE>   33
 
of exercise over the grant price of the SAR. Upon the vesting of the phantom
stock units, the holder is entitled to payment in shares of Common Stock at the
rate of one share of Common Stock for each such unit, plus dividends accrue
credits for such number of shares of Common Stock from the date of grant to the
vesting date. Restricted stock may provide the recipient all of the rights of an
Enron shareholder including the right to vote the shares and accrue any
dividends from the date of grant to the vesting date. However, the stock may not
be transferred by the recipient until certain restrictions, such as time, lapse.
 
     The 1991 Stock Plan contains several provisions so that certain awards
under the plan qualify as performance-based compensation under Section 162(m).
No individual can be granted more than 1,000,000 stock options or SARs in a
calendar year. The purchase price of a stock option or SAR cannot be less than
the fair market value of a share on the date of grant. As of March 22, 1999, the
closing price for Common Stock was $67.6875 per share. The 1991 Stock Plan
permits the grant of performance-based restricted stock which is either issued
or becomes vested based on the attainment of pre-established after tax net
income and/or cash flow criteria, at the company or subsidiary level, or is
issued in lieu of cash payments under the Enron Corp. Annual Incentive Plan or
Enron Corp. Performance Unit Plan, based on attainment of the performance
criteria established under those plans. A maximum of 100,000 shares of
performance-based restricted stock can be granted to any individual in a
calendar year.
 
     The Board of Directors cannot increase the number of shares authorized for
granting awards under the 1991 Stock Plan, increase the maximum number of
options, SARs or performance-based restricted stock that may be granted to any
individual in a calendar year, change the minimum option price, extend the
maximum period during which awards may be granted, change the class of
participants eligible to receive awards or modify the material terms of the 1991
Stock Plan, without obtaining shareholder approval.
 
CHANGES TO THE 1991 STOCK PLAN
 
     The Board of Directors desires to amend the 1991 Stock Plan to increase the
number of shares authorized for granting awards under the Plan and change the
class of participants eligible to receive awards under the Plan, which requires
shareholder approval. Amendment of several additional provisions is also
presented for approval by shareholders. The following summary description of the
proposed amendment to the 1991 Stock Plan is qualified in its entirety by
reference to the full text of the amendment which is attached to Enron's proxy
statement as Exhibit B.
 
     Among the changes effected by the proposed amendment and restatement of the
1991 Stock Plan is an increase, effective May 4, 1999, in the number of shares
of Common Stock available for granting awards under the 1991 Stock Plan. The
number of shares authorized for granting awards when the 1991 Stock Plan was
first approved in 1991 was 11,000,000 shares (2,750,000 shares adjusted for
stock splits in December 1991 and August 1993), with no more than 25% to be
granted as restricted stock. Effective May 3, 1994 and May 6, 1997, 10,000,000
shares were authorized for granting awards under the 1991 Stock Plan, again with
no more than 25% to be granted as restricted stock. Less than 1,300,000 shares
remain available for grant. The proposed amendment and restatement will
authorize 10,000,000 shares of Common Stock for granting awards under the 1991
Stock Plan effective May 4, 1999, with no more than 25% to be granted as
restricted stock and phantom stock units.
 
     Other changes to the 1991 Stock Plan being submitted to the shareholders
for approval include: (i) changing the eligibility provisions of Section 4 to
include only employees who are members of the Enron Management Committee,
nonemployee directors, and employees of Enron, its subsidiaries and affiliates
who are residents of the United Kingdom; (ii) deleting provisions for the grant
of SARs; (iii) changing the
 
                                       31
<PAGE>   34
 
performance criteria for performance-based restricted stock granted pursuant to
the provisions of Section 5.3(vi) of the 1991 Stock Plan; (iv) increasing the
number of shares pursuant to options granted annually to each nonemployee
director by 3,000 shares; and (v) to provide that in the event a nonemployee
director resigns his or her directorship with the advance approval of the
Committee, the Committee shall have discretion to fully vest grants of shares of
restricted stock made to such nonemployee director and to extend up to 12 months
from the effective date of resignation, the director's right to exercise options
granted to such director, but only as to the vested portion of such grant as of
the effective date of resignation.
 
     The recommended amendment and restatement of the 1991 Stock Plan also
incorporates amendments which have been approved by the Board of Directors since
May, 1997 which did not require shareholder approval: (i) to provide that unless
shares of restricted stock are granted in lieu of cash compensation or to
compensate for benefits lost due to statutory and/or plan earnings limits,
restrictions placed on awards of performance-based restricted stock will not
lapse in less than one year for performance-based awards, and will not lapse in
less than three years for other awards of restricted stock; and (ii) to permit
nonemployee directors whose ownership of Common Stock would result in a material
conflict of interest for business, employment or professional purposes, to
submit an opinion of counsel of such fact to the Committee with a request that
such nonemployee director not be eligible to receive further grants under the
1991 Stock Plan and to forfeit all outstanding grants made to such nonemployee
director.
 
     Approval of the amendment and restatement of the 1991 Stock Plan by the
shareholders of Enron is required in order for the plan to continue to comply
with Section 162(m) with respect to stock options and performance-based
restricted stock.
 
AWARDS UNDER THE PROPOSED AMENDMENT
 
     Benefits payable or amounts that will be granted after the effective date
of the proposed amendment and restatement of the 1991 Stock Plan are not
determinable at this time. As currently administered, awards under the 1991
Stock Plan are made available to Enron's Section 16 officers, corporate officers
and overseas employees, which is approximately 500 individuals. The proposed
amendment and restatement would define the class of eligible employees to be
consistent with the manner in which the 1991 Stock Plan is currently being
administered.
 
UNITED STATES FEDERAL INCOME TAX ASPECTS OF THE 1991 STOCK PLAN
 
     With respect to non-statutory stock options as a general rule, no federal
income tax is imposed on the optionee upon the grant of a non-statutory stock
option (an option other than an incentive stock option, which is described
below). In addition, Enron 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, Enron may claim a
deduction for compensation paid at the same time and in the same amount as
compensation income is recognized to the award recipient assuming any federal
income tax withholding requirements are satisfied. Upon a subsequent disposition
of the shares received upon exercise of a non-statutory stock option, any
appreciation after the date of exercise should qualify as a capital gain.
 
     Incentive Stock Options. The incentive stock options under the 1991 Stock
Plan are intended to constitute "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code.
                                       32
<PAGE>   35
 
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 Enron 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.
 
     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. If an
optionee disposes of shares acquired pursuant to his or her 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, Enron 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.
 
     Restricted Stock. An individual who has been granted stock under the 1991
Stock Plan will not realize taxable income at the time of grant, and Enron 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), Enron will be
entitled to a corresponding deduction. Dividend equivalents 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 Enron.
 
     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) Enron
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 paid to the
recipient during the period the forfeiture restrictions apply will be taxable as
dividends and will not be deductible by Enron, and (c) there will be no further
federal income tax consequences when the forfeiture restrictions lapse.
 
     Phantom Stock Units. A recipient of phantom stock units under the 1991
Stock Plan will generally not realize taxable income at the time of grant, and
Enron will not be entitled to a deduction at that time. At the time phantom
stock units are settled in shares of Common Stock, the recipient will have
taxable compensation income and, subject to Section 162(m) as discussed below,
Enron will receive a corresponding deduction. The measure of this income and
deduction will be the fair market value of the shares at the time the phantom
stock units are settled, plus any accrued dividend equivalents; provided,
however, that, with respect to a recipient subject to Section 16 of the Exchange
Act, unless such recipient elects otherwise, such fair market value will be
measured at the time any restrictions imposed with respect to such shares under
Section 16 of the Exchange Act subsequently lapse.
 
                                       33
<PAGE>   36
 
     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, Enron believes that the
income generated in connection with the exercise of stock options granted under
the 1991 Stock Plan should qualify as performance-based compensation and,
accordingly, Enron's deductions for such compensation should not be limited by
Section 162(m). The 1991 Stock Plan has been designed to provide flexibility
with respect to whether restricted stock awards will qualify as performance-
based compensation under Section 162(m). Enron believes that certain awards of
restricted stock under the 1991 Stock Plan will so qualify and Enron's
deductions with respect to such awards should not be limited by Section 162(m).
However, certain awards of restricted stock and all awards of phantom stock
units will not qualify as performance-based compensation and, therefore, Enron's
compensation expense deductions relating to such awards will be subject to the
Section 162(m) deduction limitation.
 
     The 1991 Stock Plan is not qualified under section 401(a) of the Internal
Revenue Code.
 
REQUIRED VOTE AND RECOMMENDATION
 
     The amendment and restatement of the 1991 Stock Plan will be approved at
the Annual Meeting if the number of votes cast in favor of the amendment exceeds
the number of votes cast opposing it. Under Oregon law, abstentions and broker
non-votes will not be counted for or against this proposal.

will be voted "FOR" the approval of the amendment to the 1991 Stock Plan.
 
     THE BOARD OF DIRECTORS RECOMMENDS VOTING "FOR" THIS PROPOSAL.
 
                                    ITEM 4.
 
          AMENDMENT OF AMENDED AND RESTATED ARTICLES OF INCORPORATION
            TO INCREASE AUTHORIZED NUMBER OF SHARES OF COMMON STOCK
 
     The Board of Directors of Enron from time to time considers the possibility
of declaring a stock split of the Enron Common Stock. However, as described
below, Enron does not have a sufficient number of authorized shares of Common
Stock to permit the Board of Directors to implement a 2-for-1 stock split.
Therefore, at the Annual Meeting of Shareholders, there will be submitted for
shareholder approval the resolutions described below that would, contingent upon
a stock split of at least 2-for-1 being declared on or before May 4, 2001, amend
the Amended and Restated Articles of Incorporation of Enron Corp. to increase
the authorized number of shares of Common Stock that Enron has authority to
issue from 600,000,000 shares to 1,200,000,000 shares (the "Charter Amendment").
 
     Shareholder approval of the following resolutions is necessary in order to
effect the Charter Amendment:
 
          RESOLVED, that the Amended and Restated Articles of Incorporation of
     Enron Corp. are hereby amended by amending the first paragraph of Article
     IV thereof to read in its entirety as follows:
 
                The total number of shares of all classes of stock which
           this Corporation shall have authority to issue is
           1,216,500,000 shares of capital stock, of which 16,500,000
           shares are Preferred Stock (the "Preferred Stock"), and
           1,200,000,000 shares are Common Stock (the "Common Stock").
 
                                       34
<PAGE>   37
 
          RESOLVED FURTHER, that the officers of Enron are hereby authorized,
     notwithstanding the authorization of the foregoing amendments by the
     shareholders of Enron, to execute and file with the Secretary of State of
     the State of Oregon the Articles of Amendment relating to such proposed
     amendment only if after May 4, 1999 and on or before May 4, 2001 Enron
     shall declare a 2-for-1 stock split effected as a dividend of one share of
     Common Stock for each outstanding share of Common Stock or a greater stock
     split effected as a dividend of shares of Common Stock on outstanding
     shares of Common Stock.
 
     If the Charter Amendment is adopted by the required vote of shareholders,
it will become effective when the appropriate Articles of Amendment to the
Amended and Restated Articles of Incorporation of Enron Corp. are filed with the
Secretary of State of the State of Oregon. However, no Articles of Amendment
will be filed unless on or prior to May 4, 2001 the Board of Directors declares
at least a 2-for-1 stock split effected as a dividend.
 
     If such a stock split is effected, each holder of record of Common Stock on
the record date established by the Board of Directors will be entitled to
receive a certificate representing the additional shares of Common Stock
issuable pursuant to the stock split and the Common Stock certificates
outstanding prior to the stock split will remain outstanding without any need
for shareholders to return certificates to Enron or to the transfer agent.
 
     Enron has been advised by tax counsel that a stock split effected as a
dividend on the Common Stock would result in no gain or loss or realization of
taxable income to holders of Common Stock under existing federal income tax
laws. Each shareholder's basis would be allocated on a pro rata basis among the
shares held on the record date for the stock split and the new shares issued in
the stock split and the holding period for the new shares would be deemed to be
the same as the holding period for the shares held on the record date. Enron
shareholders subject to taxation in jurisdictions other than the United States
should consult their tax advisers regarding the tax treatment of stock splits in
such jurisdictions.
 
     In accordance with the terms of Enron's convertible securities and various
stock option and incentive plans, in the event of a stock split, appropriate
adjustments will be made in the number of shares of Common Stock issuable and
any applicable conversion or exercise price.
 
REASONS FOR THE INCREASE IN NUMBER OF AUTHORIZED SHARES
 
     The Board of Directors believes that an increase in the number of
authorized shares of Common Stock is beneficial in the event a 2-for-1 or
greater stock split is declared. Enron is currently authorized to issue
600,000,000 shares of Common Stock, of which 351,213,484 were issued and
outstanding and 136,368,119 were reserved for issuance at the close of business
on March 8, 1999. As a result, Enron currently does not have enough authorized
shares of Common Stock to effect a 2-for-1 stock split.
 
     Although the Charter Amendment will increase the total number of authorized
shares of Common Stock by an amount substantially greater than that necessary to
effect a 2-for-1 stock split, the existing relative proportion of issued and
reserved shares to unissued shares will not change materially in the case of a
2-for-1 stock split. The Charter Amendment will therefore ensure that Enron will
continue to have additional shares available for future issuance from time to
time for proper corporate purposes, including possible future acquisitions,
stock option or other employee incentive plans or future stock splits effected
as dividends.
 
     The additional shares could potentially be issued at times and under
circumstances that could have a dilutive effect on earnings per share and on the
equity ownership and voting power of the present holders of Common Stock.
Although the flexibility of the Board of Directors to issue additional Common
Stock could enhance the Board of Directors' ability to negotiate on behalf of
the shareholders in a takeover situation and
 
                                       35
<PAGE>   38
 
also could be used by the incumbent Board of Directors to make a change of
control more difficult, the Board of Directors has no present intention of
issuing any shares of Common Stock for any anti-takeover purpose.
 
REQUIRED VOTE AND RECOMMENDATION
 
     The Charter Amendment will be approved at the Annual Meeting if the number
of votes cast in favor of the Charter Amendment exceeds the number of votes cast
opposing it. Under Oregon law, abstentions and broker non-votes will not be
counted for or against this proposal.
 
     The shares represented by the proxies solicited by the Board of Directors
will be voted as directed on the form of proxy or, if no direction is indicated,
will be voted "FOR" the approval of this proposal.

     Pursuant to the recommendation of the Audit and Compliance Committee, the
Board of Directors appointed Arthur Andersen LLP, independent public
accountants, to audit the consolidated financial statements of Enron for the
year ending December 31, 1999.
 
     The appointment of Arthur Andersen LLP as auditors of Enron will be
ratified at the Annual Meeting if the number of votes cast in favor of
ratification exceeds the number of votes cast opposing it. Under Oregon law,
abstentions and broker non-votes will not be counted for or against this
proposal.
 
     The shares represented by the proxies solicited by the Board of Directors
will be voted as directed on the form of proxy or, if no direction is indicated,
will be voted "FOR" ratification of Arthur Andersen LLP as the auditors of
Enron.
 
     In the event the appointment is not ratified, the Board of Directors will
consider the appointment of other independent auditors. A representative of
Arthur Andersen LLP is expected to be present at the Annual Meeting of
Shareholders on May 4, 1999, will be offered the opportunity to make a statement
if such representative desires to do so and will be available to respond to
appropriate questions.
 
     THE BOARD OF DIRECTORS RECOMMENDS VOTING "FOR" THIS PROPOSAL.

                                  ENRON CORP.
 
                             ANNUAL INCENTIVE PLAN
 
I. PURPOSE
 
     The Annual Incentive Plan (the "Plan") is designed to recognize, motivate,
and reward exceptional accomplishment toward annual corporation objectives; to
attract and retain quality employees; and to be market competitive.
 
II. ELIGIBILITY
 
     Only officers of the Company who are subject to the provisions of Section
16 of the Securities Exchange Act of 1934, as amended, and the requirements of
Rule 16b-3, are eligible to receive awards under this Plan.
 
III. ADMINISTRATION
 
     The Plan shall be administered by the Compensation and Management
Development Committee of the Board of Directors of Enron Corp. (the
"Committee"), which shall have the sole discretion to interpret the Plan;
approve (a) pre-established, objective, annual performance measure(s), certify
the level to which the performance measure(s) was (were) attained prior to any
payment under the Plan, approve the amount of awards made under the Plan, and
determine who shall receive any payments under the Plan. All decisions and
determinations of the Committee on all matters relating to the Plan shall be
conclusive. Members of the Committee shall not be liable for any action taken or
decision made in good faith relating to the Plan or any award thereunder. Only
the Committee shall determine who shall receive an award under the Plan and make
decisions concerning the timing, pricing, and amount of any award granted under
the Plan.
 
IV. AWARD FUND
 
     The Plan shall have an annual award fund of five percent (5%) of recurring
after-tax net income of the Company. "Recurring after-tax net income" means
after-tax net income subject to downward adjustment by the Committee in its sole
discretion for what the Committee considers unordinary or nonrecurring items of
after-tax net income and other items or events, including, but not limited to
financial impact on the Company resulting from changes in law and/or regulation
pertaining to federal taxes imposed on corporations.
 
V. INDIVIDUAL TARGET AWARD LEVELS
 
     For eligible participants subject to Internal Revenue Code Section 162(m)
("IRC 162(m)"), as amended from time to time, or applicable regulations, and for
officers who are subject to the provisions of Section 16 of the Securities
Exchange Act of 1934, an individual target award level, expressed as a
percentage of recurring after-tax net income, will be established by the
Committee. The maximum individual target award level that may be established
under the Plan is one percent (1%) of the recurring after-tax net income of the
Company in any given Plan year.
 
     The establishment of an individual award level for any participant shall
not give any participant the right to receive any payment under this Plan.
 
                                       A-1
<PAGE>   42
 
VI. PAYMENT OF AWARDS
 
     At the end of each Plan year, the Committee will verify the actual
recurring after-tax net income of the Company, if any, and the resulting award
fund, if any, taking into consideration any downward adjustments that the
Committee may make at its sole discretion, prior to authorizing any payments
under the Plan.
 
     The Committee will then determine which participants will receive payments
under the Plan, and the amount of such payments, if any.
 
     For all participants, downward adjustment of the actual award level from
the target award level may be made at the sole discretion of the Committee.
Discretionary upward adjustment of the actual award level above the target award
level shall not be allowed.
 
     Payments made under this Plan may be made in cash or other property having
equivalent value, including shares of Enron Common Stock, at the sole discretion
of the Committee, provided, however, the Committee may not authorize or make any
payment in shares of Enron Common Stock if such payment would result in more
than 1% of the then outstanding shares being issued on a cumulative basis as
payments under this Plan. Cash payments made under this Plan may be deferred
according to the terms of the Enron Corp. Deferral Plan.
 
VII. UNFUNDED NATURE OF PLAN
 
     This Plan shall constitute an unfunded mechanism for the Company to pay
incentive compensation to participants from its general assets. No fund or trust
is created with respect to the Plan, and no participant shall have any security
or other interest in the assets of the Company.
 
VIII. COMPENSATION FOR BENEFIT PLAN PURPOSES
 
     Awards made under this Plan shall not be used to determine benefit amounts
under the Company's benefit programs.
 
IX. PROHIBITION AGAINST ASSIGNMENT OR ENCUMBRANCE
 
     No right, title, interest, or benefit hereunder shall ever be subject to
any tort liability or obligations of a participant, or be subject to seizure by
any creditor of a participant or any person claiming under a participant. No
participant nor any person claiming under a participant shall have the power to
sell, transfer, pledge, anticipate, or dispose of any right, title, interest, or
benefit hereunder in any manner until the same shall have been actually
distributed free and clear of the terms of the Plan.
 
X. PLAN NOT AN EMPLOYMENT CONTRACT
 
     The Plan does not give any participant the right to be continued in
employment, and all participants remain subject to change of salary, transfer,
change of job, discipline, layoff, discharge or any other change of employment
status.
 
XI. SEVERABILITY
 
     In the event any provision of the Plan shall be held invalid or illegal for
any reason, any illegality or invalidity shall not affect the remaining parts of
the Plan, but the Plan shall be construed and enforced as if the
 
                                       A-2
<PAGE>   43
 
illegal or invalid provision had never been inserted, and the Company shall have
the privilege and opportunity to correct and remedy such questions or illegality
or invalidity by amendment as provided in the Plan.
 
XII. WITHHOLDING OF TAXES
 
     The Company shall have the right to deduct from any payment made under the
Plan any federal, state, or local taxes required by law to be withheld with
respect to such awards.
 
XIII. APPLICABLE LAW
 
     The Plan shall be governed and construed in accordance with the laws of the
State of Texas, except to the extent such laws are preempted by an applicable
federal law.
 
XIV. EFFECTIVE DATE OF PLAN
 
     Upon approval by the shareholders of the Company at the 1999 Annual
Meeting, the Plan shall be considered effective as of January 1, 1999.
 
XV. AMENDMENT AND TERMINATION OF THE PLAN
 
     The Committee may modify or terminate the Plan at any time without prior
notice to or consent of participants; provided that, without the approval of the
shareholders of the Company, no such amendment shall be made that would change
the class of participants eligible to receive awards under the Plan, fund total
payouts at a level greater than 5% of recurring after-tax net income, base the
award fund on a performance measure other than recurring after-tax net income,
increase the maximum individual target award level under the Plan, or modify any
other material terms of the Plan.

Committee shall constitute a quorum, and the acts of a majority of the members
present at any meeting at which a quorum is present, or acts approved in writing
by all members of the Committee, shall be deemed the acts of the Committee.
 
     2.2  Subject to the terms of the Plan and applicable law, the Committee
shall have sole power, authority and discretion to: (i) designate Participants;
(ii) determine the types of Awards to be granted to a Participant under the
Plan; (iii) determine the number of Shares to be covered by or with respect to
which payments, rights, or other matters are to be calculated in connection with
Awards; (iv) determine the terms and conditions of any Award; (v) determine
whether, to what extent, under what circumstances and how Awards may be settled

SECTION 3. SHARES AVAILABLE FOR AWARDS
 
     3.1  Shares Available
 
          (i) Calculation of Number of Shares Available. Effective May 4, 1999,
     the number of Shares available for granting Awards under the Plan shall be
     10 million (10,000,000) Shares, subject to adjustment as provided in
     Section 3.2.
 
          Further, if after the effective date of the Plan, any Shares covered
     by an Award granted under the Plan, or to which an Award relates, are
     forfeited, or if an Award otherwise terminates without the delivery of
     Shares or of other consideration, then the Shares covered by such Award (or
     to which such Award relates, or the number of Shares otherwise counted
     against the aggregate number of Shares available under the Plan with
     respect to such Award, to the extent of any such forfeiture or termination)
     shall again be available for granting Awards under the Plan.
 
          (ii) Accounting for Awards. For purposes of this Section 3, if an
     Award is denominated in Shares, the number of Shares covered by such Award,
     or to which such Award relates, shall be counted on the date of grant of
     such Award against the aggregate number of Shares available for granting
     Awards under the Plan; provided, however, Awards that operate in tandem
     with (whether granted simultaneously with or at a different time from)
     other Awards may be counted or not counted under procedures adopted by the
     Committee in order to avoid double counting.
 
          (iii) Sources of Shares Deliverable Under Awards. Any shares delivered
     pursuant to an Award may consist, in whole or in part, of authorized and
     unissued Shares or of treasury Shares.
 
     3.2  Adjustments
 
          (i) In the event that the Committee shall determine that any dividend
     or other distribution (whether in the form of cash, Shares, other
     securities or other property), recapitalization, stock split, reverse stock
     split, reorganization, merger, consolidation, split-up, spin-off,
     combination, repurchase or exchange of Shares or other securities of the
     Company, issuance of warrants or other rights to purchase Shares or other
     securities of the Company (or other similar corporate transaction or event)
     affects the Shares such that an adjustment 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 3.2(ii), in such manner as
     it may deem equitable, adjust any or all of (a) the number and type of
     Shares (or other securities or property) which thereafter may be made the
     subject of Awards, (b) the number and type of Shares (or other securities
     or property) subject to outstanding Awards, and (c) the grant, purchase, or
     exercise price with respect to any Award, or, if deemed appropriate, make
     provision for a cash payment to the holder of an outstanding Award;
     provided, however, that with respect to Awards 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 subject to any Award denominated in Shares shall always be a whole
     number.
 
          (ii) If, and whenever, prior to the expiration of a grant theretofore
     made, the Company shall effect a subdivision or consolidation of Shares or
     the payment of a stock dividend on Shares without receipt of consideration
     by the Company, the number of Shares 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 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 shall be proportionately reduced, and if the grant is an Option the
     purchase price per Share shall be proportionately increased.
                                       B-2
<PAGE>   46
 
SECTION 4. ELIGIBILITY
 
     Any Employee (i) who is a resident of the United Kingdom, or (ii) who is a
member of the Management Committee of the Company, and any individual who is a
Director of the Company duly elected by stockholders of the Company who is not
an Employee at the time a grant is made, shall be eligible to be designated a
Participant. However, subject to the foregoing, the only Employees who shall be
eligible to receive grants of Incentive Stock Options under the Plan shall be
those Employees who are Employees of the Company within the meaning of Section
424(e) or (f) of the Code. Grants may be made to the same individual on more
than one occasion. For purposes of this Section 4, "Management Committee" shall
mean the group of individuals who are appointed by the Chairman and either of
the Chief Executive Officer, or President of Enron Corp., to serve on such
committee.
 
SECTION 5. AWARDS
 
     5.1  Options. The Committee is hereby authorized to grant Options to
Participants with the following terms and conditions and with such additional
terms and conditions, which are not inconsistent with the provisions of the
Plan, as the Committee shall determine:
 
          (i) Exercise Price. The per Share purchase price of an Option shall
     not be less than the Fair Market Value of a Share on the date of grant of
     such Option and in no event less than the par value of a Share.
 
          (ii) Time and Method of Exercise. Subject to the provisions contained
     in the Plan and in a Participant's Award Agreement, unexercised vested
     Shares 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, Shares of Stock, other
     awards, other property or any combination thereof having a fair market
     value equal to such amount or part thereof provided that the fair market
     value of Stock so delivered shall be equal to the closing price of the
     Stock 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
     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 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
     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.
 
          (iii) Incentive Stock Options. The terms of any Incentive Stock Option
     granted under the Plan shall comply in all respects with the provisions of
     Section 422 of the Code, or any successor provision thereto, and any
     regulations promulgated thereunder.
 
          (iv) Option Agreement. Each grant of Options shall be evidenced by an
     Award Agreement which shall specify the term of the Option as well as
     vesting and termination provisions.
 
          (v) Limit on Size of Option Grants. No individual shall be granted
     Options totaling more than 1,000,000 shares in any single calendar year.
 
          (vi) Status as shareholder. Unless and until a certificate or
     certificates representing such Shares shall have been issued by the Company
     to the Participant, the Participant (or the person permitted to
                                       B-3
<PAGE>   47
 
     exercise an Option in the event of the Participant's death or incapacity)
     shall not be or have any of the rights or privileges of a shareholder of
     the Company with respect to the Shares acquirable upon an exercise of an
     Option.
 
     5.2  Restricted Stock
 
          (i) Issuance. The Committee is hereby authorized to grant Awards of
     Restricted Stock to Participants, which Awards shall be evidenced by Award
     Agreements, which shall specify vesting and termination provisions.
     Notwithstanding the foregoing, the number of Shares of Restricted Stock
     which may be granted shall be limited to not more than twenty-five percent
     (25%) of the total number of Shares available for grant under the Plan.
 
          (ii) Restrictions. Shares of Restricted Stock shall be subject to such
     restrictions as the Committee may impose (including, without limitation,
     any limitation on the right to vote a Share of Restricted Stock), which
     restrictions may lapse separately or in combination at such time or times,
     in such installments or otherwise as the Committee may deem appropriate.
     Notwithstanding the foregoing, unless Shares of Restricted Stock are
     granted in lieu of cash compensation or to compensate for benefits lost due
     to statutory and/or plan earnings limits, restrictions placed on Awards
     granted under Section 5.2(vi) herein shall lapse in not less than one year
     for performance-based Awards, and other Awards granted under this Section
     5.2 shall not lapse in total in less than three years.
 
          (iii) Certificates and Dividends. All dividends and distributions, or
     cash equivalent thereof (whether cash, stock or otherwise), on unvested
     Shares of 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 Award of
     Restricted Stock Shares, the restrictions thereon imposed by this Section
     5.2(iii) shall lapse and certificates representing such vested shares shall
     be delivered to the Participant along with all accumulated credits for
     dividends and distributions, or cash equivalent thereof attributable to
     such vested shares. 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 the Company rather than in cash. (If payment is made
     in Shares, the conversion to Shares shall be at the average Fair Market
     Value for the five trading days preceding the date of payment.) 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, except that such forfeited credits for dividends and
     distributions or cash equivalent thereof shall be canceled and shall not be
     available for future distribution under this Plan.
 
          (iv) Payment. A Participant shall not be required to make any payment
     for Awards of Restricted Stock, except to the extent otherwise required by
     law.
 
          (v) Forfeiture. Unless the Committee decides otherwise, Shares of
     non-vested Restricted Stock awarded to a Participant will be forfeited if
     the Participant terminates employment or service for any reason other than
     death, Disability, Retirement or Involuntary Termination. At the time and
     on the date of a Participant's death, Disability, Retirement or Involuntary
     Termination during the Participant's employment or service, prior to the
     date the Participant otherwise becomes fully vested in all the Restricted
     Stock awarded to the Participant, all restrictions placed on each share of
     Restricted Stock awarded to the Participant shall lapse and the non-vested
     Restricted Stock will become fully vested
 
                                       B-4
<PAGE>   48
 
     Released Securities. From and after such date the Participant or the
     Participant's estate, personal representative or beneficiary, as the case
     may be, shall have full rights of transfer or resale with respect to such
     Restricted Stock subject to applicable state and federal regulations.
 
          (vi) Performance-Based Restricted Stock. The Committee is hereby
     authorized to grant Awards 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; b) restrictions lapse contingent upon attainment of
     pre-established performance criteria; or c) the issuance is in lieu of cash
     payments under the Enron Corp. Annual Incentive Plan or the Enron Corp.
     Performance Unit Plan, based upon attainment of the performance criteria
     established under the terms of those stockholder approved plans. The
     performance criteria to be used with such Awards 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 be
     granted Awards of Restricted Stock under this Section 5.2(vi) totaling more
     than 100,000 shares 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.
 
          (vii) Phantom Stock Units. Notwithstanding any other provision of the
     Plan to the contrary, wherever under the Plan, a provision is made for the
     grant to a Director of the Company of Shares of Restricted Stock, whether
     such grant is discretionary or non-discretionary (as in Section 6), such
     grant shall be made in an equivalent number of Phantom Stock Units instead
     of Shares of Restricted Stock. An Award of Phantom Stock Units granted
     under Section 6 shall be subject to the provisions therein that apply to a
     grant of Shares of Restricted Stock. Additionally, the Committee is
     authorized to grant Awards of Phantom Stock Units to eligible persons other
     than Directors of the Company. Awards of Phantom Stock Units shall be
     evidenced by Award Agreements. Except as provided in Section 6, paragraphs
     (ii), (iii), (iv) and (v) of this Section 5.2 shall apply to Awards of
     Phantom Stock Units in similar manner as they apply to Shares of Restricted
     Stock, as interpreted by the Committee, provided, however, the limitation
     in paragraph (i) above on the number of Shares of Restricted Stock which
     may be granted shall apply to total aggregate Awards of Shares of
     Restricted Stock and Phantom Stock Units. A Phantom Stock Unit is a
     contractual obligation of the Company equal in value to one Share of the
     Company, which until paid is an unfunded bookkeeping credit on the records
     of the Company. Such credit shall be increased by the dividends per Share
     of the Company after the date of the Award. The portion of such credit
     attributable to Phantom Stock Units shall be paid under paragraph (iii)
     above in Shares of the Company.
 
     5.3  General
 
          (i) No Cash Consideration for Awards. Except as otherwise provided in
     the Plan, awards shall be granted for no cash consideration or for such
     minimal cash consideration as may be required by applicable law.
 
          (ii) Awards May be Granted Separately or Together. Awards, at the
     discretion of the Committee, may be granted either alone or in addition to,
     or in tandem with any other Award or any award granted under any other plan
     of the Company or any Affiliate. Awards granted in addition to or in tandem
     with
                                       B-5
<PAGE>   49
 
     other Awards, or in addition to or in tandem with awards granted under any
     other plan of the Company or any Affiliate, may be granted either at the
     same time as or at a different time from the grant of such other Awards or
     awards.
 
          (iii) Limits on Transfer of Awards. No Award (other than Released
     Securities) and no right under any such Award 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 Award 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 Award 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 and grandchildren).
 
     The terms and provisions of an Award Agreement 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 Award other than by will or by the laws of
descent and distribution. An Award shall be exercised only by the Participant
(or his or her attorney in fact or guardian) (including, in the case of a
transferred Award, by a Permitted Transferee), or, in the case of the
Participant's death, by the Participant's executor or administrator (including,
in the case of a transferred Award, by the executor or administrator of the
Permitted Transferee), and all exercises of an Award shall be accompanied by
sufficient payment, as determined by the Company, to meet its withholding tax
obligation on such exercise or by other arrangements satisfactory to the
Committee to provide for such payment.
 
          (iv) Term of Awards. The term of each Award shall be for such period
     as may be determined by the Committee; provided, however, that in no event
     shall the term of any Option or Stock Appreciation Right exceed a period of
     ten (10) years from the date of its grant.
 
          (v) Rule 16b-3. It is intended that the Plan and any Award made to a
     Person subject to Section 16 of the Securities Exchange Act of 1934, as
     amended, meet all of the requirements of Rule 16b-3. If any
                                       B-6
<PAGE>   50
 
     provision of the Plan or any such Award would disqualify the Plan or such
     Award under, or would otherwise not comply with, Rule 16b-3, such provision
     or Award shall be construed or deemed amended to conform to Rule 16b-3.
 
          (vi) Status of Stock. The Company intends to register for issue under
     the Securities Act of 1933, as amended ("The Act"), the Shares of Stock
     acquirable pursuant to Awards under the Plan, and to keep such registration
     effective throughout the period any Awards are in effect. In the absence of
     such effective registration or an available exemption from registration
     under the Act, delivery of Shares of Stock acquirable pursuant to Awards
     under the Plan shall be delayed until registration of such Shares is
     effective or an exemption from registration under the Act is available. The
     Company intends to use its best efforts to ensure that no such delay will
     occur. In the event exemption from registration under the Act is available,
     Participant (or Participant's estate or personal representative in the
     event of the Participant's death or incapacity), if requested by the
     Company to do so, will execute and deliver to the Company in writing an
     agreement containing such provisions as the Company may require to assure
     compliance with applicable securities laws. No sale or disposition of
     Shares of Stock acquired pursuant to an Award under the Plan by a
     Participant shall be made in the absence of an effective registration
     statement with respect to such shares under the Act unless an opinion of
     counsel satisfactory to the Company that such sale or disposition will not
     constitute a violation of the Act or any other applicable securities laws
     is first obtained. In the event that a Participant proposes to sell or
     otherwise dispose of Shares of Stock in such a manner that an exception
     from the registration requirements of the Act is unavailable for such sale
     or disposition, and upon request to the Company by the Participant, the
     Company, at its sole cost and expense, shall cause a registration statement
     to be prepared and filed with respect to such sale or disposition by the
     Participant and shall use its best efforts to have such registration
     statement declared effective, and, in connection therewith, shall execute
     and deliver such documents as shall be necessary, including without
     limitation, agreements providing for the indemnification of underwriters
     for any loss or damage incurred in connection with such sale or
     disposition.
 
          (vii) Share Certificates. All certificates for Shares or other
     securities delivered under the Plan pursuant to any Award or the exercise
     thereof shall be subject to such stop transfer orders and other
     restrictions as the Committee may deem advisable under the Plan or the
     rules, regulations and other requirements of the Securities and Exchange
     Commission, any stock exchange upon which such Shares or other securities
     are then listed and any applicable Federal or state securities laws, and
     the Committee may cause a legend or legends to be put on any such
     certificates to make appropriate reference to such restrictions, including,
     but not limited to, the provisions of Subsection 5.3(vi).
 
SECTION 6. GRANTS TO NON-EMPLOYEE DIRECTORS
 
     6.1  A. Subject to the limitation of the number of Shares and Restricted
Stock set forth in Section 3 and Section 5.2(i), each Director of the Company
who is not otherwise an employee of the Company or any Affiliate (a "nonemployee
Director"), effective during the term of the Plan on each Monday next following
the Director's election at the annual meeting of stockholders of the Company
(commencing with the 1992 annual meeting of stockholders), is hereby granted,
effective on such date, shares of Restricted Stock and an Option to purchase
Shares as determined by the provisions of the following paragraph. The Option
shall not be an Incentive Stock Option.
 
     B. The number of shares of Restricted Stock hereby granted in each year to
each nonemployee Director shall be equal to fifty percent (50%) of "A," where
"A" is equal to (i) the average Retainer Fee, on an annualized basis, paid or
payable to a nonemployee Director in the prior fiscal year, divided by (ii) the
per
                                       B-7
<PAGE>   51
 
share Fair Market Value of the Shares on the date of grant, rounded to the next
higher increment of ten. The average Retainer Fee, on an annualized basis, paid
to a nonemployee Director shall be determined by dividing the number of
nonemployee Directors serving on the Board in the previous fiscal year into the
aggregate annualized cash Retainer Fee paid to or entitled to be received by
(but for elections made by such Directors under Section 6.2 of the Plan) all
such nonemployee Directors during the Company's preceding fiscal year for
services rendered to the Company as Directors (including any deferred
compensation). "Retainer Fee" means the amount which a nonemployee Director
receives for serving as a Director, a member of a committee of the Board of
Directors of the Company or a chairperson of such a committee. The number of
Shares which is granted hereby in each year to each nonemployee Director
pursuant to an Option is equal to the sum of (i) the number of shares of
Restricted Stock granted hereby multiplied by the number four (4), and (ii)
three thousand (3,000).
 
     6.2  A. Subject to the limitation of the total number of Shares and
Restricted Stock set forth in Section 3 and Section 5.2(i), on July 1 of each
year, each nonemployee Director, who on or prior to December 31 of the previous
year files with the Committee or its designate an irrevocable election to
receive a grant under this Section 6.2 in lieu of a portion or all of the cash
amount of the projected Retainer Fees plus meeting fees for six (6) regular
meetings of the Board of Directors, such Director will be entitled to receive in
the following year beginning January 1 and ending December 31, as determined at
the time of such election (the "Aggregate Fee"), is hereby granted on such July
1, shares of Restricted Stock and an Option to purchase a number of Shares, as
determined by the provisions of the following paragraph. In making such
election, the nonemployee Director may elect a vesting date applicable to the
grant of shares of Restricted Stock to be a date not earlier than six (6) months
and not later than five (5) years from the date of grant. The Options shall not
be Incentive Stock Options.
 
     B. The number of Shares of Restricted Stock which is hereby granted on each
July 1 to a nonemployee Director making such an election is equal to fifty
percent (50%) of "A", where "A" is equal to (i) the cash amount of the portion
of such projected Aggregate Fee selected by the nonemployee Director, divided by
(ii) the per share Fair Market Value of a Share on the date of grant, rounded to
the next higher increment of ten. The number of Shares for which an Option is
hereby granted on each July 1 to such nonemployee Director is equal to the
number of shares of Restricted Stock granted hereby multiplied by the number
four (4).
 
     6.3  The following provisions are applicable to Options granted pursuant to
Sections 6.1 and 6.2:
 
     A. Options shall be exercisable according to the following provisions:
 
          (i) An Option granted pursuant to Section 6.1 shall become exercisable
     for twenty percent (20%) of the Shares covered thereby on the date of
     grant, and thereafter, for twenty percent (20%) of the Shares covered
     thereby on each of the first, second, third and fourth anniversaries of the
     grant thereof.
 
          (ii) An Option granted pursuant to Section 6.2 shall be exercisable in
     full on the date of grant.
 
     B. The purchase price of a Share covered under an Option granted under
Sections 6.1 or 6.2 shall be the Fair Market Value of a Share on the date of
grant, but not less than the par value of a Share.
 
     C. Each Option shall expire ten (10) years from the date of grant thereof,
but shall be subject to earlier termination as follows. Options, to the extent
exercisable as of the date a nonemployee Director optionee ceases to serve as a
Director of the Company, must be exercised within three months of such date
unless such event results from death, Disability or Retirement, in which case
such Options may be exercised by the
 
                                       B-8
<PAGE>   52
 
optionee, the optionee's legal representative, heir or devisee, as the case may
be, within one (1) year from the date of death, Disability or Retirement;
provided, however, that no such event shall extend the normal expiration date of
such Options.
 
     D. Upon exercise of the Option, delivery of a certificate for fully paid
and nonassessable Shares shall be made at the corporate office of the Company in
Houston, Texas to the optionee exercising the Option either at such time during
ordinary business hours after fifteen (15) days but not more than thirty (30)
days from the date of receipt of the notice by the Company as shall be
designated in such notice, or at such time, place and manner as may be agreed
upon by the Company and the optionee exercising the Option.
 
     E. That portion of Options granted under Section 6.2 to a nonemployee
Director which is attributable to a portion of the Director's Aggregate Fee
which would not have been earned due to termination of service as a Director or
a change in the Director's membership on a committee(s) of the Board of
Directors automatically shall be canceled upon such an event.
 
     6.4  The following provisions are applicable to grants of Restricted Stock
made pursuant to Sections 6.1 or 6.2, as the case may be:
 
     A. A recipient of a Restricted Stock grant made pursuant to Section 6.1
shall obtain without cost to the recipient a vested right in the Restricted
Stock so granted based on the recipient's consecutive full years of service
completed as a Director of the Company after the date of the grant in accordance
with the following table:

               5..............................................................         100%
</TABLE>
 
     B. All shares of Restricted Stock, upon vesting, shall be deemed to be
fully paid and nonassessable.
 
     C. Shares of non-vested Restricted Stock awarded to a nonemployee Director
will be forfeited if the Director terminates service as a Director for any
reason other than death, Disability or Retirement.
 
     D. At the time and on the date of a nonemployee Director's death,
Disability or Retirement during the Director's service as a Director prior to
the date the Director otherwise becomes fully vested in all the Restricted Stock
awarded to the Director, all restrictions placed on each share of Restricted
Stock awarded to the Director shall lapse and the non-vested Restricted Stock
will become fully vested Released Securities. From and after such date, the
Director or the Director's legal representative, heir or devisee, as the case
may be, shall have full rights of transfer or resale with respect to such
Restricted Stock subject to applicable state and federal regulations.
 
     6.5  A nonemployee Director shall be ineligible to receive a grant provided
for in Sections 6.1 and 6.2 if as of the date of such grant the Director (i) is
an employee of the Company or any Affiliate or (ii) has been an employee of the
Company or any Affiliate for any part of the calendar year preceding the
calendar year in which such a grant is to be made.
 
                                       B-9
<PAGE>   53
 
     6.6  In the event that the number of Shares available for grants under the
Plan is insufficient to make all grants provided for in this Section 6 hereby
made on the applicable date, then all nonemployee Directors who are entitled to
a grant on such date shall share ratably in the number of Shares then available
for grant under the Plan, and shall have no right to receive a grant with
respect to the deficiencies in the number of available Shares.
 
     6.7  Except as expressly provided in this Section 6, grants made pursuant
to this Section 6 shall be subject to the terms and conditions of the Plan;
however, if there is a conflict between the terms and conditions of the Plan and
this Section 6, then the terms and conditions of this Section 6 shall control.
 
     6.8  All Options and grants of Restricted Stock under this Section 6 shall
be evidenced by Award Agreements.
 
     6.9  In the event a nonemployee Director, as a result of employment,
business or professional interests of such nonemployee Director or Director's
spouse, becomes subject to restrictions on direct or indirect ownership of
shares of Company stock arising from participation in the Plan, and submits to
the Committee a written opinion of counsel in a form satisfactory to the
Committee that his or her continued participation in the Plan would be deemed to
be a material conflict of interest for business, employment or professional
purposes for the nonemployee Director or Director's spouse, then at the written
request to the Committee by such nonemployee Director invoking the provisions of
this Section 6.9, in a format acceptable to the Committee, such nonemployee
Director will not be eligible to receive any further grant under this general
Section 6 of the Plan until such time as the Committee is satisfied that said
restrictions have been removed or no longer apply, and as of the last day of the
month in which such written request is received by the Committee, all
outstanding grants made to such nonemployee Director under this general Section
6 of the Plan shall be forfeited and cancelled.
 
     6.10  In the event a nonemployee director resigns his or her directorship
with the Company with the advance approval of the Committee, the Committee in
giving such approval shall have discretion to fully vest grants of Restricted
Stock made to such director and to extend up to twelve months from the effective
date of such resignation the director's right to exercise Options granted to
such director, but only as to the vested portion of such Options as of the
effective date of resignation.
 
SECTION 7. AMENDMENT AND TERMINATION
 
     Except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan:
 
     7.1  Amendments to the Plan. The Board of Directors at its discretion may
terminate the Plan at any time with respect to any Shares for which a grant has
not theretofore been made. The Board of Directors 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 Award
Agreement, without the approval of the stockholders of the Company no such

transaction occurs which is not approved or recommended by a majority of the
Board of Directors of the Company in actions taken prior to, and with respect
to, such transaction in which either (i) the Company merges or consolidates with
any other corporation (other than one of the Company's wholly owned
subsidiaries) and is not the surviving corporation (or survives only as the
subsidiary of another corporation), (ii) the Company sells all or substantially
all of its assets to any other person or entity, or (iii) the Company is
dissolved, or if (iv) any third person or entity (other than the trustee or
committee of any qualified employee benefit plan of the Company), together with
its Affiliates and Associates shall be, directly or indirectly, the Beneficial
Owner of at least thirty percent (30%) of the Voting Stock of the Company, or
(v) the individuals who constitute the members of Company'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 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 (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 the Company of such merger, consolidation, sale of assets or
dissolution as described in clause (i), (ii) or (iii) of this Section 7.2A, 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 7.2A., then with
respect to outstanding grants of Restricted Stock made under Section 5.2, each
recipient thereof shall have a fully vested right in all Restricted Stock
granted to the recipient and then outstanding, and with respect to outstanding
grants of Options made under Section 5.1, 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) 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, in the case of Options, the
purchase price per Share covered by the Option and (x) equals (1) the per share
price offered to stockholders of the Company in any such merger, consolidation,
sale of assets or dissolution transaction, (2) the per share price offered to
stockholders of the Company in any tender offer or exchange offer whereby any
such change of Beneficial Ownership or Directors takes place, or (3) the Fair
Market Value of a Share on the date determined by the Committee (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. In the event that the consideration offered to
stockholders of the Company in any transaction described in this Section 7.2A
consists of anything other than cash, the Committee (as constituted prior to
such transaction) shall determine the fair cash equivalent of the portion of the
consideration offered which is other than cash.

conversion of shares or obligations of the Company convertible into such shares
or other securities, and in any case whether or not for fair value, shall not

     C. Any adjustment provided for in Section 3.2 or Section 7.2 shall be
subject to any required stockholder action.
 
     7.3  Correction of Defects, Omissions and Inconsistencies. The Committee

the Plan or any Award in the manner and to the extent it shall deem desirable in
the establishment or administration of the Plan.
 
SECTION 8. GENERAL PROVISIONS
 
     8.1  No Rights to Awards. No Employee, Participant or other Person shall
have any claim to be granted any Award under the Plan, and there is no
obligation for uniformity of treatment of Employees, Participants, or holders or
beneficiaries of Awards under the Plan. The terms and conditions of Awards need
not be the same with respect to each Participant.
 
     8.2  Withholding. The Company or any Affiliate is authorized and directed
(i) to withhold from any Award granted or any payment due or any transfer made
under any Award or under the Plan the amount (in cash, Shares, other securities,
other Awards, or other property) of withholding taxes due in respect of an
Award, its exercise, or any payment or transfer under such Award or under the
Plan, and (ii) to take such other action, including but not limited to,
acceptance of already owned Shares (including Shares acquired from the exercise
of an Option or vesting of Shares of Restricted Stock), as may be necessary to
satisfy all obligations for the payment of such taxes.
 
     8.3  No Limit on Other Compensation Arrangements. Nothing contained in the
Plan shall prevent the Company or any Affiliate from adopting or continuing in
effect other or additional compensation arrangements and such arrangements may
be either generally applicable or applicable only in specific cases.
 
     8.4  No Right to Employment. The grant of an Award shall not be construed
as giving a Participant the right to be retained in the employ of the Company or
any Affiliate. Further, the Company or an Affiliate may at any time dismiss a
Participant from employment, free from any liability or any claim under the Plan
unless otherwise expressly provided in the Plan or in any Award Agreement.
 
     8.5  Governing Law. The validity, construction and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in accordance
with applicable Federal law, and to the extent not preempted thereby, with the
laws of the State of Texas.
 
     8.6  Severability. If any provision of the Plan or any Award is or becomes
or is deemed to be invalid, illegal or unenforceable in any jurisdiction, or as
to any person or Award, or would disqualify the Plan or any Award under any law
deemed applicable by the Committee, such provision shall be construed or deemed
amended to conform to applicable laws. If it cannot be so construed or deemed
amended without, in the determination of the Committee, materially altering the
intent of the Plan or the Award, such provision shall be stricken as to such
jurisdiction, Person or Award and the remainder of the Plan and any such Award
shall remain in full force and effect.
                                      B-12
<PAGE>   56
 
     8.7  No Trust or Fund Created. Neither the Plan nor any Award shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any Affiliate and a Participant or any other
Person. To the extent that any Person acquires a right to receive payments from
the Company or any Affiliate pursuant to an Award, such right shall be no
greater than the right of any unsecured general creditor of the Company or any
Affiliate.
 
     8.8  No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or transferred
in lieu of any fractional Shares, or whether such fractional Shares or any
rights thereto shall be canceled, terminated or otherwise eliminated. In
addition, no fractional Shares shall be accepted by the Company in payment of
the exercise price of an Option.
 
     8.9  Headings. Headings are given to the Sections and Subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.
 
     8.10  No Limitation. The existence of the Plan and the grants of Awards
made hereunder shall not affect in any way the right or power of the Board of
Directors or the stockholders of the Company (or stockholders of any Affiliate,
as applicable) to make or authorize any adjustment, recapitalization,
reorganization or other change in the capital structure or business of the
Company or any Affiliate, any merger or consolidation of the Company or any
Affiliate, any issue of debt or equity securities ahead of or affecting Shares
or the rights thereof or pertaining thereto, the dissolution or liquidation of
the Company or any Affiliate or any sale or transfer of all or any part of
Company or any Affiliate's assets or business, or any other corporate act or
proceeding.
 
     8.11  No Right to Retention. Neither the Plan, nor any Award granted
pursuant to the Plan, is a contract or agreement that the Company will retain
the services of a Director or Non-employee Contractor for any period of time, or
at any particular rate of compensation, nor does it affect a right of a Director
or the Company to resign or be removed, as the case may be, from the Company's
Board of Directors.
 
     8.12  Securities Laws. Each Award granted under the Plan shall be subject
to the requirement that if at any time the Board of Directors shall determine,
in its discretion, that the listing, registration or qualification of the shares
subject to such grant upon any securities exchange or under any state or federal
law, or that the consent or approval of any government regulatory body, is
necessary or desirable as a condition of, or in connection with, such grant or
the issue or purchase of shares thereunder, such grant shall be subject to the
condition that such listing, registration, qualification, consent or approval
shall have been effected or obtained free of any conditions not acceptable to
the Board of Directors.
 
SECTION 9. EFFECTIVE DATE OF THE PLAN
 
     The Plan shall be effective as of the date of its approval by the
stockholders of the Company.
 
SECTION 10. TERM OF THE PLAN
 
     No Award shall be granted under the Plan after the earlier of (i) ten (10)
years from the date of approval of the Plan by the stockholders of the Company
pursuant to Section 9 or (ii) termination of the Plan pursuant to Section 7.1.
However, unless otherwise expressly provided in the Plan or in an applicable
Award Agreement, any Award theretofore granted may extend beyond such date, and
any authority of the Committee to amend, alter, suspend, discontinue or
terminate any such Award, or to waive any conditions or rights under
 
                                      B-13
<PAGE>   57
