                               BUSINESS OF ENRON

     Headquartered in Houston, Texas, Enron Corp. provides products and services
related to natural gas, electricity and communications to wholesale and retail
customers. Our operations are conducted through our subsidiaries and affiliates,
which are principally engaged in:


     - the marketing of natural gas, electricity and other commodities and
       related risk management and finance services worldwide;



     - the development, construction and operation of power plants, pipelines
       and other energy related assets worldwide;



     - the delivery of high bandwidth communication applications throughout the
       United States;



     - the transportation of natural gas through pipelines to markets throughout
       the United States; and



     - the generation and transmission of electricity to markets in the
       northwestern United States.



WHOLESALE ENERGY OPERATIONS AND SERVICES


     Our wholesale energy operations and services businesses operate in North
America, Europe and evolving energy markets in developing countries. These
businesses provide integrated energy-related products and services to wholesale
customers worldwide. Wholesale energy operations and services can be categorized
into two business lines: (a) Commodity Sales and Services and (b) Energy Assets
and Investments.

     Commodity Sales and Services. Our commodity sales and services operations
include:

     - the purchase, sale, marketing and delivery of natural gas, electricity,
       liquids and other commodities;

     - the restructuring of existing long-term contracts; and

     - the management of our commodity portfolios.

In addition, we provide risk management products and services to energy
customers that hedge movements in price and location-based price differentials.
Our risk management products and services are designed to provide stability to
customers in markets impacted by commodity price volatility. Also included in
this business is the management of certain operating assets that directly relate
to this business, including domestic intrastate pipeline and storage facilities.

     Energy Assets and Investments. In the assets and investments business, we
manage and operate a large portfolio of assets related to natural gas,
electricity and communications and offer financing alternatives to customers.
Activities include developing, constructing, operating and managing a large
portfolio of energy assets, including power plants and natural gas pipelines. We
also provide capital to energy and communication customers seeking debt or
equity financing.


     Enron Broadband Services provides high quality broadband Internet content
and applications. This business includes the Enron Intelligent Network(TM)
("EIN"), Enron's Broadband Operating System, and bandwidth trading,
intermediation and content services. Enabled with a software control layer, the
EIN provides a bandwidth-on-demand platform to deliver data, applications and
streaming rich media to the desktop. We are minimizing capital deployed in the
development of the EIN through strategic alliances with industry technology
leaders whose presence, customer access, market share and content enable us to
efficiently enter this new, emerging marketplace. We are extending the market
making and risk management skills from our energy business to develop the
bandwidth intermediation business. Content services include premium broadband
content delivery, such as video streaming, high capacity data transport and
video conferencing, that utilize the EIN platform.


RETAIL ENERGY SERVICES

     Enron Energy Services is a nationwide provider of energy outsource products
to United States business customers. This includes sales of natural gas and
electricity and energy management services directly to
                                        3
<PAGE>   6

commercial and industrial customers, as well as investments in related
businesses. Enron Energy Services provides end-users with a broad range of
energy products and services at competitive prices. These products and services
include energy tariff and information management, demand-side services and
financial services.


TRANSPORTATION AND DISTRIBUTION



     Our transportation and distribution business is comprised of our North
American interstate natural gas transportation systems and our electricity
transmission and distribution operations in Oregon.



     Interstate Transmission of Natural Gas. Included in our domestic interstate
natural gas pipeline operations are Northern Natural Gas Company, Transwestern
Pipeline Company and Florida Gas Transmission Company (indirectly 50% owned by
our company). Northern, Transwestern and Florida Gas are interstate pipelines
and are subject to the regulatory jurisdiction of the Federal Energy Regulatory
Commission. Each pipeline serves customers in a specific geographical area.
Northern serves the upper Midwest, Transwestern serves principally the
California market and pipeline interconnects on the east end of the Transwestern
system, and Florida Gas serves the State of Florida. In addition, we hold an
interest in Northern Border Partners, L.P., which owns a 70% interest in the
Northern Border Pipeline system. One of our subsidiaries operates the Northern
Border Pipeline system, which transports gas from Western Canada to delivery
points in the midwestern United States.



     Electricity Transmission and Distribution Operations. We conduct our
electric utility operations through our wholly-owned subsidiary, Portland
General Electric Company. Portland General is engaged in the generation,
purchase, transmission, distribution and sale of electricity in the State of
Oregon. Portland General also sells energy to wholesale customers throughout the
western United States. Portland General's Oregon service area is approximately
3,170 square miles. At December 31, 1999, Portland General served approximately
719,000 customers. On November 8, 1999, we announced that we have entered into
an agreement to sell Portland General to Sierra Pacific Resources for $2.1
billion, comprised of $2.02 billion in cash and the assumption of our
approximately $80 million Portland General merger payment obligation. Sierra
Pacific Resources will also assume $1 billion in Portland General debt and
preferred stock. The proposed transaction, which is subject to customary
regulatory approvals, is expected to close in late 2000.



                                USE OF PROCEEDS


     The net proceeds from the sale of the offered securities will be added to
our general funds and will be used to repay debt and for general corporate
purposes. Other uses may be stated in a prospectus supplement.

- ---------------

(a)  For the year ended December 31, 1997, earnings were inadequate to cover
     combined fixed charges and preferred stock dividends by $6 million.

     The ratios of earnings to fixed charges and preferred stock dividends are
based on continuing operations. "Earnings" is determined by adding:

     - the pre-tax income of Enron and its majority owned subsidiaries,

     - Enron's share of pre-tax income of its 50% owned companies,

                                        4
<PAGE>   7

     - any income actually received from less than 50% owned companies, and

     - fixed charges, net of interest capitalized.

"Fixed Charges" represent (1) interest (whether expensed or capitalized), (2)
amortization of debt discount and expense and (3) that portion of rentals
considered to be representative of the interest factor. "Fixed Charges and
Preferred Stock Dividends" represent fixed charges (as described above) and
preferred stock dividend requirements of Enron and its majority owned
subsidiaries.

                         DESCRIPTION OF DEBT SECURITIES

     The following description highlights the general terms and provisions of
the debt securities. When debt securities are offered in the future, the
prospectus supplement will explain the particular terms of those securities and
the extent to which these general provisions may apply.

     The debt securities will be secured or unsecured obligations of Enron. Any
unsecured obligations will be issued under an "Indenture" between Enron and
Harris Trust and Savings Bank, as Trustee, dated as of November 1, 1985, as
supplemented. Any secured obligations will be issued under a separate indenture,
which will be described in the prospectus supplement relating to those debt
securities.


     We have summarized selected provisions of the Indenture below. The summary
is not complete. The form of the Indenture has been filed as an exhibit to the
registration statement and you should read the Indenture for any provisions that
may be important to you. In the summary below, we have included references to
section numbers of the Indenture so that you can easily locate these provisions.
Capitalized terms used in the summary have the meanings specified in the
Indenture.


GENERAL


     The Indenture does not limit the principal amount of unsecured debentures,
notes or other obligations of Enron (the "Indenture Securities") which we may
issue from time to time in one or more series, and we may issue additional
Indenture Securities (in addition to the debt securities) in the future under
the Indenture. At December 31, 1999, we had approximately $5,145,913,000
principal amount of Indenture Securities issued and outstanding under the
Indenture.


     A prospectus supplement relating to any series of debt securities being
offered will include specific terms relating to the offering. These terms will
include some or all of the following:

     - The title of the debt securities;

     - The total principal amount of the debt securities;

     - The date on which the principal of the debt securities is payable;

     - The interest rate which the debt securities will bear and the interest
       payment dates for the debt securities;

     - The place where the principal of (and premium, if any) and interest on
       debt securities will be payable;

     - Any optional redemption periods and the terms of that option;

     - Any sinking fund or other provisions that would obligate us to repurchase
       or otherwise redeem the debt securities;

     - Any trustees, paying agents, transfer agents or registrars with respect
       to debt securities; and

     - Any other terms of the debt securities. (Section 301.)

LIMITATIONS ON MORTGAGES AND LIENS

     The Indenture provides that so long as any of the Indenture Securities
(including the debt securities) are outstanding, Enron will not, and will not
permit any Subsidiary to, pledge, mortgage or hypothecate, or permit to exist,
except in favor of Enron or any Subsidiary, any mortgage, pledge or other lien
upon, any Principal

                                        5
<PAGE>   8

Property at any time owned by it, to secure any indebtedness (as defined in the
Indenture), unless effective provision is made whereby outstanding Indenture
Securities (including the debt securities) will be equally and ratably secured
with any and all such indebtedness and with any other indebtedness similarly
entitled to be equally and ratably secured. This restriction does not apply to
prevent the creation or existence of:

     - Mortgages, pledges, liens or encumbrances on any property held or used by
       Enron or a Subsidiary in connection with the exploration for, development
       of or production of, oil, gas, natural gas (including liquified gas and
       storage gas), other hydrocarbons, helium, coal, metals, minerals, steam,
       timber, geothermal or other natural resources or synthetic fuels, such
       properties to include, but not be limited to, Enron's or a Subsidiary's
       interest in any mineral fee interests, oil, gas or other mineral leases,
       royalty, overriding royalty or net profits interests, production payments
       and other similar interests, wellhead production equipment, tanks, field
       gathering lines, leasehold or field separation and processing facilities,
       compression facilities and other similar personal property and fixtures;

     - Mortgages, pledges, liens or encumbrances on oil, gas, natural gas
       (including liquified gas and storage gas), other hydrocarbons, helium,
       coal, metals, minerals, steam, timber, geothermal or other natural
       resources or synthetic fuels produced or recovered from any property, an
       interest in which is owned or leased by Enron or a Subsidiary;

     - Mortgages, pledges, liens or encumbrances (or certain extensions,
       renewals or refundings thereof) upon any property acquired before or
       after the date of the Indenture, created at the time of acquisition or
       within one year thereafter to secure all or a portion of the purchase
       price thereof, or existing thereon at the date of acquisition, whether or
       not assumed by Enron or a Subsidiary, provided that every such mortgage,
       pledge, lien or encumbrance applies only to the property so acquired and
       fixed improvements thereon;

     - Mortgages, pledges, liens or encumbrances upon any property acquired
       before or after the date of the Indenture by any corporation that is or
       becomes a Subsidiary after the date of the Indenture ("Acquired Entity"),
       provided that every such mortgage, pledge, lien or encumbrance (1) shall
       either (a) exist prior to the time the Acquired Entity becomes a
       Subsidiary or (b) be created at the time the Acquired Entity becomes a
       Subsidiary or within one year thereafter to secure all or a portion of
       the acquisition price thereof and (2) shall only apply to those
       properties owned by the Acquired Entity at the time it becomes a
       Subsidiary or thereafter acquired by it from sources other than Enron or
       any other Subsidiary;

     - Pledges of current assets, in the ordinary course of business, to secure
       current liabilities;

     - Deposits to secure public or statutory obligations;

     - Liens to secure indebtedness other than Funded Debt (as defined in the
       Indenture and herein);

     - Mortgages, pledges, liens or encumbrances upon any office, data
       processing or transportation equipment;

     - Mortgages, pledges, liens or encumbrances created or assumed by Enron or
       a Subsidiary in connection with the issuance of debt securities the
       interest on which is excludable from gross income of the holder of such
       security pursuant to the Internal Revenue Code of 1986, as amended, for
       the purpose of financing the acquisition or construction of property to
       be used by Enron or a Subsidiary;

     - Pledges or assignments of accounts receivable or conditional sales
       contracts or chattel mortgages and evidences of indebtedness secured
       thereby, received in connection with the sale by Enron or a Subsidiary of
       goods or merchandise to customers; or

     - Certain other liens or encumbrances. (Section 1007.)

     Notwithstanding the foregoing, Enron or a Subsidiary may issue, assume or
guarantee indebtedness secured by a mortgage which would otherwise be subject to
the foregoing restrictions in an aggregate amount which, together with all other
indebtedness of Enron or a Subsidiary secured by a mortgage which (if

                                        6
<PAGE>   9

originally issued, assumed or guaranteed at such time) would otherwise be
subject to the foregoing restrictions (not including secured indebtedness
permitted under the foregoing exceptions), does not at the time exceed 10% of
the Consolidated Net Tangible Assets (total assets less (a) total current
liabilities, excluding indebtedness due within 12 months, and (b) goodwill,
patents and trademarks) of Enron, as shown on the audited consolidated financial
statements of Enron as of the end of the fiscal year preceding the date of
determination. (Section 1007.)

     The holders of at least 50% in principal amount of the outstanding
Indenture Securities under the Indenture (including the debt securities) may
waive compliance by Enron with the covenant contained in Section 1007 of the
Indenture (and certain other covenants of Enron). (Section 1009.)

     "Subsidiary" is defined to mean a corporation all of the voting shares
(that is, shares entitled to vote for the election of directors, but excluding
shares entitled so to vote only upon the happening of some contingency unless
such contingency shall have occurred) of which shall be owned by Enron or by one
or more Subsidiaries or by Enron and one or more Subsidiaries. The term
"Principal Property" is defined to mean any oil or gas pipeline, gas processing
plant or chemical plant located in the United States, except any such property,
pipeline or plant that in the opinion of the Board of Directors of Enron is not
of material importance to the total business conducted by Enron and its
Subsidiaries. "Principal Property" does not include any oil or gas property or
the production or any proceeds of production from an oil or gas producing
property or the production or any proceeds of production of gas processing
plants or oil or gas or petroleum products in any pipeline. (Section 101.)

     The term "indebtedness", as applied to Enron or any Subsidiary, is defined
to mean bonds, debentures, notes and other instruments representing obligations
created or assumed by any such corporation for the repayment of money borrowed
(other than unamortized debt discount or premium). All indebtedness secured by a
lien upon property owned by Enron or any Subsidiary and upon which indebtedness
any such corporation customarily pays interest, even though such corporation has
not assumed or become liable for the payment of such indebtedness, is also
deemed to be indebtedness of any such corporation. All indebtedness for money
borrowed incurred by other persons which is directly guaranteed as to payment of
principal by Enron or any Subsidiary is for all purposes of the Indenture deemed
to be indebtedness of any such corporation, but no other contingent obligation
of any such corporation in respect of indebtedness incurred by other persons is
for any purpose deemed indebtedness of such corporation. Indebtedness of Enron
or any Subsidiary does not include (1) amounts which are payable only out of all
or a portion of the oil, gas, natural gas, helium, coal, metals, minerals,
steam, timber or other natural resources produced, derived or extracted from
properties owned or developed by such corporation; (2) any amount representing
capitalized lease obligations; (3) any indebtedness incurred to finance oil,
gas, natural gas, helium, coal, metals, minerals, steam, timber, hydrocarbons or
geothermal or other natural resources or synthetic fuel exploration or
development, payable, with respect to principal and interest, solely out of the
proceeds of oil, gas, natural gas, helium, coal, metals, minerals, steam,
timber, hydrocarbons or geothermal or other natural resources or synthetic fuel
to be produced, sold and/or delivered by Enron or any Subsidiary; (4) indirect
guarantees or other contingent obligations in connection with the indebtedness
of others, including agreements, contingent or otherwise, with such other
persons or with third persons with respect to, or to permit or ensure the
payment of, obligations of such other persons, including, without limitation,
agreements to purchase or repurchase obligations of such other persons,
agreements to advance or supply funds to or to invest in such other persons or
agreements to pay for property, products or services of such other persons
(whether or not conferred, delivered or rendered) and any demand charge,
throughput, take-or-pay, keep-well, make-whole, cash deficiency, maintenance of
working capital or earnings or similar agreements; and (5) any guarantees with
respect to lease or other similar periodic payments to be made by other persons.
(Section 101.)

     "Funded Debt" as applied to any corporation means all indebtedness
incurred, created, assumed or guaranteed by such corporation, or upon which it
customarily pays interest charges, which matures, or is renewable by such
corporation to a date, more than one year after the date as of which Funded Debt
is being determined; provided, however, that the term "Funded Debt" shall not
include (1) indebtedness incurred in the ordinary course of business
representing borrowings, regardless of when payable, of such corporation from
time to time against, but not in excess of the face amount of, its installment
accounts receivable for the sale of
                                        7
<PAGE>   10

appliances and equipment sold in the regular course of business or (2) advances
for construction and security deposits received by such corporation in the
ordinary course of business. (Section 101.)

     The foregoing limitations on mortgages, pledges and liens are intended to
limit other creditors of Enron from obtaining preference or priority over
holders of the Indenture Securities issued under the Indenture, but are not
intended to prevent other creditors from sharing equally and ratably and without
preference ("pari passu") over the holders of such Indenture Securities. While
such limitations on mortgages and liens do provide protection to the holders of
the Indenture Securities, there are a number of exceptions to such restrictions
which could result in certain assets of Enron and its Subsidiaries being
encumbered without equally and ratably securing the Indenture Securities issued
under the Indenture. Specifically, the restrictions apply only to pledges,
mortgages or liens upon "Principal Property" (as defined in the Indenture and
herein) to secure any "indebtedness" (as defined in the Indenture and herein),
unless effective provision is made whereby outstanding Securities will be
equally and ratably secured with any such indebtedness and with any other
indebtedness similarly entitled to be equally and ratably secured. There are
certain exceptions to the definition of "indebtedness," which are enumerated in
the Indenture and herein. In addition, the restrictions do not apply to prevent
the creation or existence of mortgages, pledges, liens or encumbrances on
certain types of properties or pursuant to certain types of transactions, all as
enumerated in the Indenture and above. Also, up to 10% of Consolidated Net
Tangible Assets (as defined in the Indenture and herein) is not subject to the
mortgage and lien limitations contained in the Indenture.

     Unless otherwise indicated in a Prospectus Supplement, the covenants
contained in the Indenture and the Indenture Securities would not necessarily
afford holders of the Indenture Securities protection in the event of a highly
leveraged or other transaction involving Enron that may adversely affect
holders.

MODIFICATION OF THE INDENTURE

     With certain exceptions, the Indenture provides that Enron and the Trustee
may modify the Indenture or the rights of the holders of Indenture Securities if
they have the consent of the holders of at least 50% in principal amount of all
outstanding Indenture Securities affected thereby. However, no modification of
the principal or interest payment terms, no modification of provisions
concerning waivers of past defaults or waivers of certain covenants, and no
modification reducing the percentage required for any modifications, is
effective against any holder without its consent. (Section 902.)

EVENTS OF DEFAULT AND RIGHTS UPON DEFAULT

     "Event of Default" means any one of the following with respect to any
series of Indenture Securities:

          (a) failure to pay interest on any Indenture Security of that series
     for 30 days;

          (b) failure to deposit any sinking fund payment for 30 days;

          (c) failure to pay the principal or any premium on any Indenture
     Security of that series when due;

          (d) failure to perform any other covenant in the Indenture for 60 days
     after being given written notice by the Trustee or the holders of at least
     25% in principal amount of all outstanding Indenture Securities; or

          (e) certain events in bankruptcy, receivership or other insolvency
     proceedings or an assignment for the benefit of creditors. (Section 501.)

     An Event of Default for a particular series of Indenture Securities does
not necessarily constitute an Event of Default for any other series of Indenture
Securities issued under the Indenture. A default under other indebtedness of
Enron is not an Event of Default under the Indenture.

     If an Event of Default for any series of Indenture Securities occurs and
continues, the Trustee or the holders of at least 25% in principal amount of the
outstanding Indenture Securities of that series may declare the principal amount
of all of the Indenture Securities of that series to be due and payable
immediately. If an Event of Default described in clause (d) or (e) of the
foregoing paragraph occurs and is continuing, the
                                        8
<PAGE>   11

Trustee or the holders of at least 25% in principal amount of all of the
Indenture Securities then outstanding may declare the principal amount of all of
the Indenture Securities to be due and payable immediately. (Section 502.) If
this happens, subject to certain conditions, the holders of a majority of the
aggregate principal amount of the outstanding Indenture Securities of that
series (or of all series, as the case may be) may rescind and annul such
declaration and its consequences, if, subject to certain conditions, all Events
of Default with respect to Indenture Securities of that series (or of all
series, as the case may be), other than the non-payment of the principal of the
Indenture Securities due solely by such declaration of acceleration, have been
cured or waived and all payments due (other than by acceleration) have been paid
or deposited with the Trustee. With certain exceptions, the holders of not less
than a majority in principal amount of the outstanding Indenture Securities of
any series, on behalf of the holders of all the Indenture Securities of such
series, may waive any past default described in clause (a), (b) or (c) of the
first paragraph under this subheading (or, in the case of a default described in
clause (d) or (e) of such paragraph, the holders of a majority in principal
amount of all outstanding Indenture Securities may waive any such past default)
and its consequences, except a default (1) in the payment of the principal of
(or premium, if any) or interest on any Indenture Security, or (2) in respect of
a covenant or provision of the Indenture which under the Indenture cannot be
modified or amended without the consent of the holder of each outstanding
Indenture Security of such series affected. (Section 513.)

DISCHARGE OF INDENTURE; DEFEASANCE

     With certain exceptions, we will be discharged from our obligations under
the Indenture with respect to any series of Indenture Securities by either
paying or causing to be paid the principal of, premium, if any, and interest on
all of the Indenture Securities of such series outstanding, as and when the same
shall become due and payable, or delivering to the Trustee all outstanding
Indenture Securities of such series for cancellation. (Section 401.)

     In addition, we will be discharged if at any time we defease the Indenture
Securities of a series by depositing in escrow or trust with the Trustee
sufficient cash and/or Government Obligations and/or Eligible Obligations to pay
the principal of, premium, if any, and interest on the Indenture Securities of
that series to the stated maturity date or a redemption date for the Indenture
Securities of that series. If that happens, payment of the Indenture Securities
of such series may not be accelerated because of an event specified as a default
or Event of Default with respect to such Indenture Securities, and the holders
of the Indenture Securities of such series will not be entitled to the benefits
of the Indenture, except for registration of transfer and exchange of Indenture
Securities and replacement of lost, stolen or mutilated Indenture Securities.

     The Indenture defines "Eligible Securities" to mean interest bearing
obligations as a result of the deposit of which the Indenture Securities are
rated in the highest generic long-term debt rating category assigned to defeased
debt by one or more nationally recognized rating agencies.

     Under Federal income tax law as of the date of this prospectus, a discharge
may be treated as an exchange of the related debt securities. Each holder might
be required to recognize gain or loss equal to the difference between the
holder's cost or other tax basis for the debt securities and the value of the
holder's interest in the trust. Holders might be required to include as income a
different amount than would be includable without the discharge. Prospective
investors are urged to consult their own advisors as to the tax consequences of
a discharge, including the applicability and effect of tax laws other than
Federal income tax law.

FORM, DENOMINATION AND REGISTRATION; BOOK ENTRY ONLY SYSTEM

     Unless otherwise indicated in a prospectus supplement, the debt securities
will be issued only in fully registered form, without coupons, in denominations
of $1,000 or integral multiples thereof. (Section 302.) You will not have to pay
a service charge to transfer or exchange debt securities, but we may require you
to pay for taxes or other governmental charges due upon a transfer or exchange.
(Section 305.)

     Unless otherwise indicated in a prospectus supplement, each series of
Indenture Securities will be deposited with, or on behalf of, The Depository
Trust Company ("DTC") or any successor depositary (the
                                        9
<PAGE>   12

"Depositary") and will be represented by one or more Global Notes registered in
the name of Cede & Co., as nominee of DTC. The interests of beneficial owners in
the Global Notes will be represented through financial institutions acting on
their behalf as direct or indirect participants in DTC.

     Ownership of beneficial interests in a Global Note will be limited to
persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in the Global
Notes will be shown on, and the transfer of these ownership interests will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants).

     So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Indenture Securities of that series represented by
such Global Note for all purposes of the Indenture, the Indenture Securities of
that series and applicable law. In addition, no beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures (in addition to those under the Indenture).

     Payments on Indenture Securities represented by Global Notes will be made
to DTC or its nominee, as the registered owner thereof. Neither we, the Trustee,
any underwriter nor any paying agent will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in Global Notes, for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests or for any
action taken or omitted to be taken by the Depositary or any participant.

     We expect that DTC or its nominee will credit participants' accounts on the
payable date with payments in respect of a Global Note in amounts proportionate
to their respective beneficial interest in the principal amount of such Global
Note as shown on the records of DTC or its nominee, unless DTC has reason to
believe that it will not receive payment on the payable date. We also expect
that payments by participants to owners of beneficial interests in such Global
Note held through such participants will be governed by standing instructions
and customary practices, as is now the case with securities held for the
accounts of customers registered in "street name." Such payments will be the
responsibility of such participants.

     Transfers between participants in DTC will be effected in accordance with
DTC rules. The laws of some states require that certain persons take physical
delivery of securities in definitive form. Consequently, the ability to transfer
beneficial interests in a Global Note to such persons may be impaired. Because
DTC can only act on behalf of participants, who in turn act on behalf of others,
such as securities brokers and dealers, banks and trust companies ("indirect
participants"), the ability of a person having a beneficial interest in a Global
Note to pledge such interest to persons or entities that do not participate in
the DTC system, or otherwise take actions in respect of such interest, may be
impaired by the lack of a physical certificate of such interest.

     We believe it is the policy of DTC to take any action permitted to be taken
by a holder of Indenture Securities of a series only at the direction of one or
more participants to whose account interests in Global Notes are credited and
only in respect of such portion of the aggregate principal amount of the
Indenture Securities of a series as to which such participant or participants
has or have given such direction.

     If (1) the Depositary notifies us that it is unwilling or unable to
continue as Depositary or if the Depositary ceases to be eligible under the
Indenture and a successor depositary is not appointed by us within 90 days or
(2) an event of default with respect to a series of Indenture Securities shall
have occurred and be continuing, the respective Global Notes representing the
affected series of Indenture Securities will be exchanged for Indenture
Securities in definitive form of like tenor and of an equal aggregate principal
amount, in authorized denominations. Such definitive Indenture Securities shall
be registered in such name or names as the Depositary shall instruct the
Trustee. Such instructions will most likely be based upon directions received by
the Depositary from participants with respect to ownership of beneficial
interests in Global Notes.

     DTC has advised us as follows: DTC is a limited-purpose trust company
organized under the New York Banking Law, a "banking organization" within the
meaning of the New York Banking Law, a member of the
                                       10
<PAGE>   13

Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC holds securities that its
participants deposit with DTC and facilitates the settlement among participants
of securities transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in participants'
accounts, thereby eliminating the need for physical movement of securities
certificates. Direct participants include securities brokers and dealers, banks,
trust companies, clearing corporations and certain other organizations. DTC is
owned by a number of its direct participants, including those who may act as
underwriters of our Indenture Securities, and by the New York Stock Exchange,
Inc., the American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. Access to the DTC system is also available to others
such as indirect participants that clear through or maintain a custodial
relationship with a direct participant, either directly or indirectly. The rules
applicable to DTC and its participants are on file with the SEC.

     DTC has further advised us that management of DTC is aware that some
computer applications, systems, and the like for processing data that are
dependent upon calendar dates, including dates before, on, and after January 1,
2000, may encounter "Year 2000 problems." DTC has informed its participants and
other members of the financial community that it has developed and is
implementing a program so that its systems, as the same relate to the timely
payment of distributions (including principal and interest payments) to security
holders, book-entry deliveries, and settlement of trades within DTC, continue to
function appropriately. This program includes a technical assessment and a
remediation plan, each of which DTC reports is complete. Additionally, DTC's
plan includes a testing phase, which DTC expects to be completed within
appropriate time frames.

     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as the DTC's direct and indirect participants and third party vendors from
whom DTC licenses software and hardware, and third party vendors on whom DTC
relies for information or the provision of services, including telecommunication
and electrical utility service providers, among others. DTC has informed the
industry that it is contacting (and will continue to contact) third party
vendors from whom DTC acquires services to: (1) impress upon them the importance
of such services being Year 2000 compliant; and (2) determine the extent of
their efforts for Year 2000 remediation (and, as appropriate, testing) of their
services. In addition, DTC is in the process of developing such contingency
plans as it deems appropriate.

     According to DTC, the foregoing information with respect to DTC has been
provided to the industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in Global Notes among participants of DTC, it is under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Neither we, the Trustee, any
underwriter nor any paying agent will have any responsibility for the
performance by DTC or its participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.

CONCERNING THE TRUSTEE

     Harris Trust and Savings Bank is the Trustee under the Indenture. The bank
also may act as a depository of funds for, make loans to, and perform other
services for, Enron in the normal course of business, including acting as
trustee under other indentures of Enron. The corporate trust office of the
Trustee is located at 311 West Monroe, Chicago, Illinois, 60690.

     The holders of a majority in principal amount of the outstanding securities
issued under the Indenture will have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
Trustee, subject to certain exceptions. The Indenture provides that if an Event
of Default occurs (and it is not cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent person in the
conduct of such person's own affairs. Subject to such provisions, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request of any
                                       11
<PAGE>   14

holder of securities issued under the Indenture, unless such holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, liability or expense, and then only to the extent required by the terms of
the Indenture. The Trustee may resign from its duties with respect to the
Indenture at any time or may be removed by Enron. If the Trustee resigns, is
removed or becomes incapable of acting as Trustee or a vacancy occurs in the
office of the Trustee for any reason, a successor Trustee shall be appointed in
accordance with the provisions of the Indenture. (Article Six.)

     The Indenture contains the provisions required by the Trust Indenture Act
of 1939 with reference to the disqualification of the Trustee if it shall have
or acquire any "conflicting interest", as therein defined. (Section 608.) The
Indenture also contains certain limitations on the right of the Trustee, as a
creditor of Enron, to obtain payment of claims in certain cases, or to realize
on certain property received by it in respect of any such claims, as security or
otherwise. (Section 613.)

are entitled to receive ratably such dividends, if any, as may be declared by
the Board of Directors of Enron out of legally available funds subject to the
rights of any preferred stock. In the event of liquidation, dissolution or
winding up of Enron, the holders of Enron common stock are entitled to share
ratably in all assets of Enron remaining after provision for payment of
liabilities and satisfaction of the liquidation preference of any shares of
Enron preferred stock that may be outstanding. The holders of Enron common stock
have no preemptive, subscription, redemption or conversion rights. The rights,
preferences and privileges of holders of Enron common stock are subject to those
of holders of Enron preferred stock, including any series of Enron preferred
stock issued in the future.


PREFERRED STOCK

     The following is a general description of the terms of our preferred stock.
If we offer preferred stock, the specific designations and rights will be
described in the prospectus supplement and a description will be filed with the
SEC.

                                       12

     The preferred stock shall rank in preference to the common stock as to
payment of dividends and as to distribution of assets of Enron upon the
liquidation, dissolution or winding up of Enron. Upon issuance against full
payment of the purchase price therefor, shares of preferred stock will be fully
paid and nonassessable.


     Enron is authorized to issue up to 16,500,000 shares of preferred stock. An
aggregate of 1,370,000 shares of Enron preferred stock are designated the
Cumulative Second Preferred Convertible Stock ("Enron Convertible Preferred
Stock"), an aggregate of 35.568509 shares of Enron preferred stock are
designated the 9.142% Perpetual Second Preferred Stock ("Enron 9.142% Preferred
Stock"), an aggregate of 250,000 shares of Enron preferred stock are designated
the Mandatory Convertible Junior Preferred Stock, Series B ("Enron Mandatorily
Convertible Junior Preferred Stock"), an aggregate of 204,800 shares of Enron
preferred stock are designated the Mandatorily Convertible Single Reset
Preferred Stock, Series A ("Enron Mandatorily Convertible Preferred Stock,
Series A"), and 83,000 shares of Enron preferred stock are designated the
Mandatorily Convertible Single Reset Preferred Stock, Series B ("Enron
Mandatorily Convertible Preferred Stock, Series B" and together with the Enron
Mandatorily Convertible Preferred Stock, Series A, the "Enron Mandatorily
Convertible Preferred Stock").



     In addition to the Enron Convertible Preferred Stock, the Enron 9.142%
Preferred Stock, the Enron Mandatorily Convertible Junior Preferred Stock and
the Enron Mandatorily Convertible Preferred Stock, the Enron Board of Directors
has authority, without shareholder approval (except to the extent that holders
of any series of Enron preferred stock are entitled by their terms to class
voting rights), to issue shares of Enron preferred stock in one or more series
and to determine the number of shares, designations, dividend rights, conversion
rights, voting power, redemption rights, liquidation preferences and other terms
of any such series. The issuance of Enron preferred stock, while providing
desired flexibility in connection with possible acquisitions and other corporate
purposes, could adversely affect the voting power of holders of Enron common
stock and the likelihood that such holders will receive dividend payments and
payments upon liquidation and could have the effect of delaying, deferring or
preventing a change in control of Enron.


ENRON CONVERTIBLE PREFERRED STOCK

     We have summarized the terms of the Enron Convertible Preferred Stock
below. The summary is not complete. The form of series designation for the Enron

     The annual rate of dividends payable on shares of the Enron Convertible
Preferred Stock is the greater of $10.50 per share or the dividend amount
payable on the number of shares of Enron common stock into which one share of
Enron Convertible Preferred Stock is convertible (currently 27.304 shares,

of January, April, July and October. These dividend rights are superior to the
dividend rights of the Enron common stock, the Enron Mandatorily Convertible
Junior Preferred Stock and the Enron Mandatorily Convertible Preferred Stock and
rank equally with the dividend rights on the Enron 9.142% Preferred Stock.



     The amount payable on shares of the Enron Convertible Preferred Stock in
the event of any involuntary or voluntary liquidation, dissolution or winding up
of the affairs of Enron is $100 per share, together with accrued dividends to
the date of distribution or payment. The liquidation rights of the Enron
Convertible Preferred Stock are superior to the Enron common stock, the Enron
Mandatorily Convertible Junior Preferred Stock and the Enron Mandatorily
Convertible Preferred Stock and rank equally with the liquidation rights of the

redeemable at the option of Enron at any time, in whole or in part, at a
redemption price of $100 per share, together with accrued dividends to the date
of payment. Each share of Enron Convertible Preferred Stock is convertible into
27.304 shares of Enron common stock at any time at the option of the holder
(which conversion rate is and will be subject to certain adjustments).


     Holders of Enron Convertible Preferred Stock are entitled to vote together
with the Enron common stock on all matters submitted to a vote of Enron
shareholders, with each share of Enron Convertible Preferred Stock having a
number of votes equal to the number of shares of Enron common stock into which

              - an amendment to the Enron Charter or Bylaws that would affect
                adversely the voting powers, rights or preferences of the
                holders of the Enron Convertible Preferred Stock or that would
                reduce the time for any notice to which the holders of the Enron
                Convertible Preferred Stock may be entitled,

              - the authorization, creation or issuance of, or the increase in
                the authorized amount of, any stock of any class or series or
                any security convertible into stock of any class or series

              - the purchase or redemption (for sinking fund purposes or
                otherwise) of less than all of the Enron Convertible Preferred

                sum sufficient for payment thereof set apart, and

        (b) the requirement for approval by the holders of at least a majority

                authorization, creation or issuance by Enron of a number of
                shares of one or more series of preferred stock ranking on

              - the merger or consolidation of Enron with or into any other
                corporation, unless the corporation resulting from such merger
                or consolidation will have after such merger or consolidation no
                class of stock and no other securities either authorized or

                stock and the same amount of other securities with the same
                rights and preferences as the stock and securities of Enron
                respectively authorized and outstanding immediately preceding
                such merger or consolidation, and each holder of Enron
                Convertible Preferred Stock immediately preceding such merger or
                consolidation shall receive the same number of shares, with the
                same rights and preferences, of the resulting corporation.

In addition, if dividend payments on the Enron Convertible Preferred Stock are

then the holders of the Enron Convertible Preferred Stock (together with holders
of any parity stock similarly affected) shall be able to elect two directors to
Enron's Board of Directors until such dividends have been paid or funds
sufficient therefor deposited in trust. If we fail to pay dividends when due on

and our subsidiaries from acquiring junior stock, including Enron common stock,
subject to certain exceptions.

ENRON MANDATORILY CONVERTIBLE JUNIOR PREFERRED STOCK



     We have summarized the terms of the Enron Mandatorily Convertible Junior
Preferred Stock below. The summary is not complete. The form of the statement of
resolutions establishing the Enron Mandatorily Convertible Junior Preferred
Stock has been filed as an exhibit to this registration statement, and you

Convertible Junior Preferred Stock is 6.5%. The amount payable on shares of the

dividend and liquidation rights of the Enron common stock, but rank junior to
the dividend and liquidation rights of all other outstanding series of Enron
preferred stock. The Enron Mandatorily Convertible Junior Preferred Stock is not
redeemable at the option of Enron. Each share of Enron Mandatorily Convertible
Junior Preferred Stock is convertible initially into 200 shares of Enron common
stock (which conversion rate is subject to certain adjustments).



     The holders of Enron Mandatorily Convertible Junior Preferred Stock
generally have no voting rights but are entitled to certain class voting rights,
including the requirement for approval by the holders of at least a majority of
the Enron Mandatorily Convertible Junior Preferred Stock (voting together with

       powers, rights or preferences of the holders of the Enron Mandatorily

       Stock immediately preceding such merger or consolidation shall receive
       the same number of shares, with substantially the same rights and
       preferences, of the surviving corporation.



In addition, if full cumulative dividends are not paid for six consecutive
quarterly periods, the holders of the Enron Mandatorily Convertible Junior
Preferred Stock (together with the holders of any parity stock similarly
affected) will have the right to elect two directors to Enron's Board of

have been paid or funds sufficient therefor deposited in trust. If we fail to
pay dividends when due on this preferred stock, the terms of this preferred
stock will prohibit us from paying dividends on junior stock, including Enron
common stock, and prohibit us and our subsidiaries from acquiring junior stock,
including Enron common stock, subject to certain exceptions.

ENRON MANDATORILY CONVERTIBLE PREFERRED STOCK

     We have summarized the terms of the Enron Mandatorily Convertible Preferred
Stock, Series A and Series B, below. The summary is not complete. The terms of
the Series A and the Series B are generally the same except as discussed below.
The forms of the statement of resolutions establishing both series of the Enron
Mandatorily Convertible Preferred Stock have been filed as exhibits to this
registration statement, and you should read the forms for any terms that may be
important to you.


     The shares of each of the two series of the Enron Mandatorily Convertible
Preferred Stock were deposited under deposit agreements, and the related
depositary shares were then deposited into trusts of which we are the beneficial
owner. The depositary shares are to be sold by the trusts only if a default
occurs under certain of our debt obligations or under certain debt obligations
that were incurred in connection with our investment in Wessex Water Plc and
Elektro-Eletricidade e Servicos S.A. (the "Obligations") or our credit ratings
fall below investment grade and, in the case of Series A, our common stock price
falls below $18.92, subject to certain adjustments. The date that the depositary
shares are sold by the trust, or under certain circumstances the date the
depositary shares were to have been sold but were unable to be sold, is the Rate
Reset Date, and the market price of Enron common stock on the day such sale is
priced is the Reset Price, subject to certain adjustments. If the Obligations,
which generally mature on or before December 2001, are timely repaid in full, we
expect the Enron Mandatorily Convertible Preferred Stock will be retired and
canceled.



     No dividends are payable on the Enron Mandatorily Convertible Preferred
Stock prior to the applicable Rate Reset Date. After a Rate Reset Date, the
annual rate of dividends payable is $350 per share plus an amount which is
intended to approximate the dividend yield on the Enron common stock as of the
Rate Reset Date. Such dividends are payable quarterly and are cumulative. The
amount payable on shares of Enron Mandatorily Convertible Preferred Stock in the
event of any liquidation, dissolution or winding up of the affairs of Enron is
$5,000 per share, together with accrued dividends to the date of payment. These
dividend and liquidation rights are superior to the dividend and liquidation
rights of the Enron common stock and the Enron Mandatorily Convertible Junior
Preferred Stock, but rank junior to the dividend and liquidation rights of the
Enron Convertible Preferred Stock and Enron 9.142% Preferred Stock.


     The Enron Mandatorily Convertible Preferred Stock is not redeemable after
the Rate Reset Date. The Enron Mandatorily Convertible Preferred Stock will be
converted into Enron common stock on the third anniversary of the Rate Reset
Date. The number of shares issuable per share of Enron Mandatorily Convertible
Preferred Stock on conversion will equal the liquidation preference ($5,000)
divided by the conversion price. The conversion price will be between 100% to
110% of the applicable Reset Price (subject to certain adjustments) depending on
the market price of Enron common stock at the time of conversion. After the Rate
Reset Date and prior to the third anniversary of the Rate Reset Date, the
holders of the Enron Mandatorily Convertible Preferred Stock will be entitled to
convert such shares into Enron common stock based on a conversion price of 110%
of the Reset Price (subject to certain adjustments).

     The holders of each series of Enron Mandatorily Convertible Preferred Stock
generally have no voting rights, but are entitled to certain class voting
rights, including the requirement for approval by the holders of at least a
majority of each series to effect:

     - an amendment to the Enron Charter that would adversely affect the powers,
       rights or preferences of the holders of such series of Enron Mandatorily
       Convertible Preferred Stock,

     - the authorization or issuance of capital stock ranking senior to the
       Enron Mandatorily Convertible Preferred Stock, or

                                       17
<PAGE>   20

     - the merger or statutory exchange in which holders of the Enron
       Mandatorily Convertible Preferred Stock do not receive a similar
       preferred stock in the surviving entity, subject to certain exceptions.

     If the Obligations are not paid when due, the holders of each series of
Enron Mandatorily Convertible Preferred Stock will have the right to elect two
directors to Enron's Board of Directors until such debt is paid or certain other
events occur. In addition, if full cumulative dividends are not paid for six
consecutive quarterly periods, the holders of the Enron Mandatorily Convertible
Preferred Stock (together with the holders of any parity stock similarly
affected) will have the right to elect two directors to Enron's Board of
Directors until all dividends in arrears have been paid. If we fail to pay
dividends when due on Enron Mandatorily Convertible Preferred Stock, the terms
of the Enron Mandatorily Convertible Preferred Stock will prohibit us from
paying dividends on junior stock, including Enron common stock, and prohibit us
and our subsidiaries from acquiring junior stock, including Enron common stock,
subject to certain exceptions.

CERTAIN PROVISIONS OF THE ENRON CHARTER AND BYLAWS

     Fair Price Provision. The Enron Charter contains a "fair price" provision
which generally requires that certain mergers, business combinations and similar
transactions with a "Related Person" (generally the beneficial owner of at least
10 percent of Enron's voting stock) be approved by the holders of at least 80
percent of Enron's voting stock, unless (a) the transaction is approved by at
least 80 percent of the "Continuing Directors" of Enron, who constitute a
majority of the entire board, (b) the transaction occurs more than five years
after the last acquisition of Enron voting stock by the Related Person or (c)
certain "fair price" and procedural requirements are satisfied.

     "Business Transaction" means (a) any merger or consolidation involving
Enron or a subsidiary of Enron, (b) any sale, lease, exchange, transfer or other
disposition (in one transaction or a series of transactions), including without
limitation a mortgage or any other security device, of all or any substantial
part of the assets either of Enron or of a subsidiary of Enron, (c) any sale,
lease, exchange, transfer or other disposition of all or any substantial part of
the assets of an entity to Enron or a subsidiary of Enron, (d) the issuance,
sale, exchange, transfer or other disposition by Enron or a subsidiary of Enron
of any securities of Enron or any subsidiary of Enron, (e) any recapitalization
or reclassification of Enron's securities (including without limitation, any
reverse stock split) or other transaction that would have the effect of
increasing the voting power of a Related Person, (f) any liquidation, spinoff,
splitoff, splitup or dissolution of Enron, and (g) any agreement, contract or
other arrangement providing for any of the transactions described in this
definition of Business Transaction.

     "Continuing Director" means a director who either was a member of the Board
of Directors of Enron prior to the time such Related Person became a Related
Person or who subsequently became a director of Enron and whose election, or
nomination for election by Enron's shareholders, was approved by a vote of at
least 80 percent of the Continuing Directors then on the Board, either by a
specific vote or by approval of the proxy statement issued by Enron on behalf of
the Board of Directors in which such person is named as nominee for director,
without an objection to such nomination; provided, however, that in no event
shall a director be considered a "Continuing Director" if such director is a
Related Person and the Business Transaction to be voted upon is with such
Related Person or is one in which such Related Person otherwise has an interest
(except proportionately as a shareholder of Enron).

     Advance Notice Requirements for Shareholder Proposals and Nominations. The
Enron Bylaws provide that for business to be properly brought before an annual
meeting of shareholders, it must be either (a) specified in the notice of

principal executive offices not less than 120 days prior to the anniversary date
of the proxy statement for the previous year's annual meeting of the

     The Enron Bylaws provide that only persons who are nominated for election

than those made by or at the direction of the Board of Directors, shall be made
pursuant to timely notice in writing to the Secretary of Enron. To be timely, a
shareholder's notice must be delivered to or mailed and received at Enron's
principal executive offices, (i) with respect to an election to be held at an

Secretary shall set forth (a) as to each person whom the shareholder proposes to
nominate for election or re-election as a director, all information relating to
the person that is required to be disclosed in solicitations for proxies for
election of directors, or is otherwise required, pursuant to Regulation 14A

(b) as to the shareholder giving the notice, (i) the name and address, as they
appear on Enron's books, of such shareholder, and (ii) the class and number of

CERTAIN ANTI-TAKEOVER PROVISIONS OF OREGON LAW

     Business Combinations with Interested Shareholders. Enron is subject to the
provisions of Sections 60.825-60.845 of the Oregon Business Corporation Act
("OBCA"), which generally provide that any person who acquires 15% or more of a
corporation's voting stock (thereby becoming an "interested shareholder") may
not engage in certain "business combinations" with the corporation for a period
of three years following the date the person became an interested stockholder,
unless (i) the board of directors has approved, prior to the date the person
became an interested shareholder, either the business combination or the
transaction that resulted in the person becoming an interested shareholder, (ii)
upon consummation of the transaction that resulted in the person becoming an
interested shareholder, that person owns at least 85% of the corporation's
voting stock outstanding at the time the transaction is commenced (excluding
shares owned by persons who are both directors and officers and shares owned by
employee stock plans in which participants do not have the right to determine
whether shares will be tendered in a tender or exchange offer), or (iii) on or
subsequent to the date the person became an interested shareholder, the business
combination is approved by the board of directors and authorized by the
affirmative vote of at least 66 2/3% of the outstanding voting stock not owned
by the interested shareholder.

     Control Share Statute. As is permitted by the OBCA, the Enron Charter
provides that Enron is not subject to the Oregon Control Share Act. The Oregon
Control Share Act restricts the ability of a shareholder of certain Oregon-based
corporations to vote shares of stock acquired in a transaction that causes the
acquiring person to control at least one-fifth, one-third or one-half of the
votes entitled to be cast in the election of directors, except as authorized by
a vote of the corporation's disinterested shareholders.

                        DESCRIPTION OF DEPOSITARY SHARES

GENERAL

     We may choose to offer fractional interests in the preferred stock. If so,
we will offer depositary shares, each of which will represent a fraction (to be
set forth in the prospectus supplement relating to a particular series of
preferred stock) of a share of a particular series of preferred stock as
described below.

     The preferred stock of any series represented by depositary shares will be
deposited under a deposit agreement between Enron and a bank or trust company
selected by Enron having its principal office in the United States and having,
alone or together with its affiliates, a combined capital and surplus of at
least $50,000,000 (the "Depositary"). Subject to the terms of the deposit
agreement, each registered holder of a depositary share will be entitled, in
proportion to the applicable fraction of a share of preferred stock represented
by such depositary share, to all the rights and preferences of the preferred
stock represented thereby (including dividend, voting, redemption and
liquidation rights).

     The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Depositary receipts will be distributed to
those persons purchasing the fractional interests in preferred stock in
accordance with the terms of the offering set forth in the applicable prospectus
supplement.

     We have summarized the terms of the depositary shares below. The summary is
not complete. A copy of the form of deposit agreement is filed as an exhibit to
the registration statements of which this prospectus is a part, and you should
read the exhibit for any terms that may be important to you.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The Depositary will distribute all dividends or other cash distributions
received in respect of the preferred stock to the record holders of depositary
shares relating to such preferred stock in proportion to the number of such
depositary shares owned by such holders.

     In the event of a distribution other than in cash or rights, preferences or
privileges upon the preferred stock, the Depositary will distribute property
received by it to the record holders of depositary shares entitled thereto in
proportion to the number of such depositary shares owned by such holders, unless
the Depositary determines that such distribution cannot be made proportionately
among such holders or that it is not feasible to make such distribution, in
which case the Depositary may, with the approval of Enron, sell such securities
or property and distribute the net proceeds from such sale to such holders or
adopt such other method as it deems equitable and practicable for effecting such
distribution.

WITHDRAWAL OF THE PREFERRED STOCK

     Upon surrender of the depositary receipts at the corporate trust office of
the Depositary (unless the related preferred stock or depositary shares have
previously been called for redemption), and upon payment of the charges provided
in the deposit agreement and subject to the terms thereof, the holder of the
depositary shares evidenced thereby is entitled to delivery at such office to or
upon his order the number of whole shares of preferred stock and any money or
other property represented by such depositary shares. If the depositary receipts
delivered by the holder evidence a number of depositary shares in excess of the
number of depositary shares representing the number of whole shares of preferred
stock to be withdrawn, the Depositary will deliver to such holder at the same
time a new depositary receipt evidencing such excess number of depositary
shares. Holders of preferred stock thus withdrawn, and any subsequent holders of
those shares, will not thereafter be entitled to deposit such shares under the
deposit agreement or to receive depositary shares therefor.

REDEMPTION OF DEPOSITARY SHARES

     Upon redemption of preferred stock represented by depositary shares, the
Depositary will redeem as of the same redemption date the number of depositary
shares representing preferred stock so redeemed, provided Enron shall have paid
in full to the Depositary the redemption price of the preferred stock to be
redeemed (which redemption price shall include an amount equal to any accrued
and unpaid dividends thereon to the
                                       20
<PAGE>   23

date fixed for redemption). The redemption price per depositary share will be
equal to the applicable fraction of the redemption price and any other amounts
per share payable with respect to the preferred stock. If fewer than all the
depositary shares are to be redeemed, the depositary shares to be redeemed will
be selected by the Depositary by lot or pro rata or by any other equitable
method, in each case as may be determined by Enron.

VOTING OF THE PREFERRED STOCK

     Upon receipt of notice of any meeting at which the holders of the preferred
stock are entitled to vote, the Depositary will mail the information contained
in such notice of meeting to the record holders of the depositary shares. Each
record holder of such depositary shares on the record date (which will be the
same date as the record date for the preferred stock) will be entitled to
instruct the Depositary as to the exercise of the voting rights pertaining to
the amount of preferred stock represented by such holder's depositary shares.
The Depositary will endeavor, insofar as practicable, to vote the number of
shares of preferred stock represented by such depositary shares in accordance
with such instructions, and Enron will agree to take all reasonable action which
may be deemed necessary by the Depositary in order to enable the Depositary to
do so. The Depositary will abstain from voting preferred stock (but, at its
discretion, not from appearing at any meeting with respect to such preferred
stock) to the extent it does not receive specific instructions from the holders
of depositary shares representing preferred stock.

AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

     The form of depositary receipt evidencing the depositary shares and any
provision of the deposit agreement may at any time be amended by agreement
between Enron and the Depositary. However, any amendment which materially and
adversely alters the rights of the holders of depositary shares will not be
effective unless such amendment has been approved by the holders of at least a
majority of the depositary shares then outstanding.

     The deposit agreement may be terminated by Enron upon not less than 60
days' notice, whereupon the Depositary shall deliver or make available to each
holder of depositary receipts, upon surrender of the depositary receipts held by
such holder, such number of whole or fractional shares of preferred stock
represented by such depositary receipts. The deposit agreement will
automatically terminate if (i) all outstanding depositary shares have been
redeemed, or (ii) there has been a final distribution in respect of the
preferred stock in connection with any liquidation, dissolution or winding up of
Enron and such distribution has been made to the holders of depositary receipts.

CHARGES OF DEPOSITARY

     Enron will pay all transfer and other taxes and governmental charges
arising solely from the existence of the Depositary arrangements. Enron will pay
the fees and expenses of the Depositary in connection with the performance of
its duties under the deposit agreement, to the extent specified in the deposit
agreement. Holders of depositary receipts will pay transfer and other taxes and
governmental charges.

MISCELLANEOUS

     Enron will forward to holders of depositary shares any reports and
communications that it sends to holders of preferred stock.

     Neither the Depositary nor Enron will be liable if it is prevented from or
delayed in, by law or any circumstances beyond its control, performing its
obligations under the deposit agreement. The obligations of Enron and the
Depositary under the deposit agreement will be limited to performing their
duties thereunder without negligence or willful misconduct, and Enron and the
Depositary will not be obligated to prosecute or defend any legal proceeding in
respect of any depositary shares or any preferred stock unless satisfactory
indemnity is furnished. Enron and the Depositary may rely on advice of counsel
or accountants, on information provided by holders of depositary shares or other
persons believed to be authorized or competent and on documents believed to be
genuine.

                                       21
<PAGE>   24

     In the event the Depositary shall receive conflicting claims, requests or
instructions from any holders of depositary receipts, on the one hand, and
Enron, on the other hand, the Depositary shall be entitled to act on such
claims, requests or instructions received from Enron.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The Depositary may resign at any time by delivering to Enron notice of its
election to do so, and Enron may at any time remove the Depositary, any such
resignation or removal to take effect upon the appointment of a successor
Depositary and its acceptance of such appointment. Such successor Depositary
must be appointed within 60 days after delivery of the notice of resignation or
removal and must be a bank or trust company having its principal office in the
United States and having, alone or together with its affiliates, a combined
capital and surplus of at least $50,000,000.

                              PLAN OF DISTRIBUTION

     We may sell the offered securities (a) through agents; (b) through
underwriters or dealers; (c) directly to one or more purchasers; or (d) pursuant
to delayed delivery contracts or forward contracts.

BY AGENTS

     Offered securities may be sold through agents designated by us. The agents
agree to use their reasonable best efforts to solicit purchases for the period
of their appointment.

BY UNDERWRITERS

     If underwriters are used in the sale, the offered securities will be
acquired by the underwriters for their own account. The underwriters may resell
the securities in one or more transactions, including negotiated transactions,
at a fixed public offering price or at varying prices determined at the time of
sale. The obligations of the underwriters to purchase the securities will be
subject to certain conditions. The underwriters will be obligated to purchase
all the securities of the series offered if any of the securities are purchased.
Any initial public offering price and any discounts or concessions allowed or
re-allowed or paid to dealers may be changed from time to time.

DIRECT SALES


     Offered securities may also be sold directly by us. In this case, no
underwriters or agents would be involved. We may use electronic media, including
the Internet, to sell offered securities directly.


DELAYED DELIVERY CONTRACTS OR FORWARD CONTRACTS

     If indicated in the prospectus supplement, we will authorize agents,
underwriters or dealers to solicit offers to purchase offered securities from us
at the public offering price set forth in the prospectus supplement pursuant to
delayed delivery contracts or forward contracts providing for payment or
delivery on a specified date in the future at prices determined as described in
the prospectus supplement. Such contracts will be subject only to those
conditions set forth in the prospectus supplement, and the prospectus supplement
will set forth the commission payable for solicitation of such contracts.

GENERAL INFORMATION

     The offered securities (other than common stock, which is traded on the New
York Stock Exchange under the symbol "ENE"), when first issued, will have no
established trading market. Any underwriters or agents to or through whom
offered securities are sold for public offering and sale may make a market in
such offered securities, but such underwriters or agents will not be obligated
to do so and may discontinue any market making at any time without notice. No
assurance can be given as to the liquidity of the trading market for any such
offered securities.

                                       22
<PAGE>   25

     The offered securities may or may not be listed on a national securities
exchange. No assurances can be given that there will be a market for the offered
securities.

     Underwriters, dealers and agents that participate in the distribution of
the offered securities may be underwriters as defined in the Securities Act of
1933, and any discounts or commissions received by them from us and any profit
on the resale of the offered securities by them may be treated as underwriting
discounts and commissions under the Act. Any underwriters or agents will be
identified and their compensation described in a prospectus supplement.

     We may have agreements with the underwriters, dealers and agents to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act of 1933, or to contribute with respect to payments which the
underwriters, dealers or agents may be required to make.

     Underwriters, dealers and agents or their affiliates may engage in
transactions with, or perform services for, us or our subsidiaries in the
ordinary course of their businesses.

                             VALIDITY OF SECURITIES


     The validity of the offered securities will be passed upon for Enron by
James V. Derrick, Jr., Esq., Executive Vice President and General Counsel of
Enron. Mr. Derrick owns substantially less than 1% of the outstanding shares of
common stock of Enron.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Enron Charter contains provisions under which Enron will indemnify, to
the fullest extent permitted by law, persons who are made a party to an action
or proceeding by virtue of the fact that the individual is or was a director,
officer, or, in certain circumstances, an employee or agent, of Enron or another
corporation at Enron's request. The Oregon Business Corporation Act generally
permits such indemnification to the extent that the individual acted in good
faith and in a manner which he reasonably believed to be in the best interest of
or not opposed to the corporation or, with respect to criminal matters, if the
individual had no reasonable cause to believe his or her conduct was unlawful.
In addition, the Enron Charter contains a provision that eliminates the personal
liability of a director to the corporation or its shareholders for monetary
damages for conduct as a director, except for liability of a director (i) for
breach of the duty of loyalty, (ii) for actions or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii) for
the payment of improper dividends or redemptions, or (iv) for any transaction
from which the director derived an improper personal benefit.

     The Form of Underwriting Agreement filed as Exhibit 1 hereto, under certain
specified circumstances, provides for indemnification by the Underwriters of the
directors, officers and controlling persons of Enron.

     Enron has purchased liability insurance policies covering the directors and
officers of Enron to provide protection where Enron cannot legally indemnify a
director or officer and where a claim arises under the Employee Retirement
Income Security Act of 1974 against a director or officer based on an alleged
breach of fiduciary duty or other wrongful act.

ITEM 17. UNDERTAKINGS

     The undersigned Registrant, Enron Corp., hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to each Registration Statement:

             (i) To include any prospectus required in Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of each Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statements;

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statements
        or any material change to such information in the Registration
        Statements;


     provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in the Registration Statements;


          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment that contains a
     form of prospectus shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof;

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering; and

                                      II-3
<PAGE>   30

          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of Enron's annual report pursuant to
     Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that
     is incorporated by reference in the Registration Statement shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 above, or
otherwise, the Registrant have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of such registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, such Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

          C.        Dividends.

                     (1) The holders of the Mandatorily Convertible Junior
           Preferred Stock, Series B, in preference to the rights of holders of
           any junior stock but subject to the rights of any senior stock,
           shall be entitled to receive, as and when declared by the Board of
           Directors out of any funds legally available therefor, cash
           dividends, at a rate, at all times during each Limited Dividend
           Period and Dividend Period, equal to 6.5%, calculated on the amount
           of the liquidation value of $4,000 per share, and no more provided,
           however, that at any time from and after the occurrence of an Event
           of Default under Sections 9.01(a) or (b) of the Indenture, the
           dividends on the Mandatorily Convertible Junior Preferred Stock,
           Series B shall accumulate at a rate, at all times during the
           continuance of any such Event of Default and for each Limited
           Dividend Period and Dividend Period occurring therein, equal to
           8.3%, calculated on the amount of the liquidation value of $4,000
           per share, and no more (as in effect from time to time, the
           "Dividend Rate"), payable semi-annually on each January 9 and July
           9 following the end of each Initial Dividend Period (each such date
           being hereinafter referred to as an "Initial Dividend Payment
           Date"), or if an Initial Dividend Payment Date is not a Business
           Day, then the Initial Dividend Payment Date shall be the next
           succeeding Business Day. After the Remarketing Date, such dividends
           shall be payable quarterly on each January 9, April 9, July 9 and
           October 9 following the end of each Dividend Period. Such dividends
           shall be cumulative from and shall accrue on all shares of the
           Mandatorily Convertible Junior Preferred Stock, Series B from the
           beginning of the first Initial Dividend Period. All computations of
           the Dividend Rate shall be made on the basis of a year of 360 days
           for the actual number of days included in the Initial Dividend
           Period or Dividend Period.

                     (2) No dividend shall be paid upon, or declared or set

           Stock, Series B or shares ranking on parity with the Mandatorily
           Convertible Junior Preferred Stock, Series B for any dividend period
           unless at the same time a like proportionate dividend for the same
           dividend period, ratable in proportion to the respective annual
           dividend rates fixed therefor, shall be paid upon, or declared and
           set apart for, all shares of Mandatorily Convertible Junior
           Preferred Stock, Series B and any Preferred Stock ranking on parity
           with the Mandatorily Convertible Junior Preferred Stock, Series B
           that are entitled to such dividends.

                     (3) Until such time as all shares of Mandatorily
           Convertible Junior Preferred Stock, Series B shall have been
           canceled pursuant to subparagraph F(12) below, in no event at any
           time shall any dividend, whether in cash or property, be paid or
           declared, nor shall any distribution be made, on any junior stock,
           nor shall any shares of any junior stock be purchased, redeemed or
           otherwise acquired for value by the Corporation, nor shall the
           Corporation permit any shares of any junior stock to be purchased,
           redeemed or otherwise acquired by any subsidiary of the Corporation,
           unless full cumulative dividends on the Mandatorily Convertible
           Junior Preferred Stock, Series B scheduled to be paid at or prior to
           such time pursuant to paragraph C(1) have been declared and paid.
           The foregoing provisions of this subparagraph (3) shall not,
           however, apply to (i) a dividend payable solely in any junior stock,
           (ii) the acquisitions of shares of any junior stock in exchange for,
           or through application of the proceeds of the sale of, shares of any
           other junior stock, (iii) the acquisitions of shares of any junior
           stock pursuant to contractual obligations binding against the
           Corporation or any of its subsidiaries that were entered into prior
           to the date of the first issuance of shares of Mandatorily
           Convertible Junior Preferred Stock, Series B or that are entered
           into at a time when such acquisitions of shares could be made
           pursuant to this subparagraph (3) or (iv) the dividend, distribution
           or issuance of Rights. "Rights" means rights or warrants distributed
           by the Corporation under a shareholder rights plan or agreement to
           all holders of Common Stock entitling the holders thereof to
           subscribe for or purchase shares of the Corporation's capital stock
           (either initially or under certain circumstances), which rights or
           warrants, until the occurrence of a specified event or events
           ("Trigger Events"):

                               (a)  are deemed to be transferred with such
               shares of Common Stock,

                               (b)  are not exercisable, and

                               (c)  are also issued in respect of future
               issuances of  Common Stock.

                     (4) In no event will any dividend or distribution be made
           on or in respect of Mandatorily Convertible Junior Preferred Stock,
           Series B other than in cash without the consent of all the holders
           of the Mandatorily Convertible Junior Preferred Stock, Series B.

           D. Liquidation Preference. In the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, then, before any distribution or payments shall be made to the
holders of any junior stock, but subject to the rights of any senior stock or
parity stock, the holders of the Mandatorily Convertible Junior Preferred
Stock, Series B shall be entitled to be paid in full in cash the amount of
$4,000 per share, together with accrued dividends to the date of such
distribution or payment, whether or not earned or declared. If such payment
shall have been made in full to the holders of the Mandatorily Convertible
Junior Preferred Stock, Series B and all preferential payments or distributions
to be made with respect to senior stock and parity stock have been made in
full, the remaining assets and funds of the Corporation shall be distributed
among the holders of the junior stock, according to their respective rights and
preferences and in each case according to their respective shares. If, upon any
liquidation, dissolution or winding up of the affairs of the Corporation, the
amounts so payable are not paid in full to the holders of all shares of the

                                     5



<PAGE>   6
Mandatorily Convertible Junior Preferred Stock, Series B and parity stock, the
holders of the Mandatorily Convertible Junior Preferred Stock, Series B,
together with holders of parity stock, shall share ratably in any distribution
of assets in proportion to the full amounts to which they would otherwise be
respectively entitled. Neither the consolidation or merger of the Corporation,
nor the sale, lease or conveyance of all or a part of its assets, shall be
deemed a liquidation, dissolution or winding up of the affairs of the
Corporation within the meaning of the foregoing provisions of this paragraph D
or paragraph G hereof.

           E. Redemption.  The Corporation shall not have the right to redeem
any or all of the Mandatorily  Convertible Junior Preferred Stock, Series B at
any time.

           F.  Conversion Rights.

                     (1) Unless previously converted at the option of the
           holder in accordance with the provisions hereof, on the third
           anniversary of the Settlement Date (other than a Settlement Date
           occurring by reason of the occurrence of a Failed Remarketing), or
           if such date is not a Business Day, the next succeeding day that is
           a Business Day ( the "Mandatory Conversion Date"), each outstanding
           share of Mandatorily Convertible Junior Preferred Stock, Series B
           shall, without additional notice to holders thereof, convert
           automatically (the "Mandatory Conversion") into (i) a number of
           fully paid and non-assessable shares of Common Stock at the
           Conversion Rate (as defined herein) in effect on the Mandatory
           Conversion Date; and (ii) the right to receive an amount in cash
           equal to all accrued and unpaid dividends on such share of
           Mandatorily Convertible Junior Preferred Stock, Series B (other than
           previously declared dividends payable to a holder of record as of a
           prior date) to and including the day immediately prior to the
           Mandatory Conversion Date, whether or not earned or declared, out of
           funds legally available therefor (and if sufficient funds are not
           then legally available therefor, the Corporation shall pay such
           amount, if any, pro rata (based on the amounts so owing) to the
           holders of the Mandatorily Convertible Junior Preferred Stock,
           Series B and any parity stock then entitled to similar payment as is
           then legally available therefor and shall pay any deficiency
           thereafter as soon as funds are legally available therefor).
           Dividends on the Mandatorily Convertible Junior Preferred Stock,
           Series B shall cease to accrue, and Mandatorily Convertible Junior
           Preferred Stock, Series B shall cease to be outstanding, on the
           Mandatory Conversion Date. The Corporation shall make such
           arrangements as it deems appropriate for the issuance of
           certificates representing Common Stock and for the payment of cash
           in respect of such accrued and unpaid dividends, if any, or cash in
           lieu of fractional shares, if any, in exchange for and contingent
           upon surrender of certificates representing the Mandatorily
           Convertible Junior Preferred Stock, Series B, and the Corporation
           may defer the payment of dividends on such Common Stock and the
           voting thereof until, and make such payment and voting contingent
           upon, the surrender of such certificates representing the
           Mandatorily Convertible Junior Preferred Stock, Series B, provided
           that the Corporation shall give the holders of the Mandatorily
           Convertible Junior Preferred Stock, Series B such notice of any such
           actions as the Corporation deems appropriate and upon such surrender
           such holders shall be entitled to receive such dividends declared
           and paid on such Common Stock subsequent to the Mandatory Conversion
           Date. Amounts payable in cash in respect of the Mandatorily
           Convertible Junior Preferred Stock, Series B or in respect of such
           Common Stock shall not bear interest.


                                     6
<PAGE>   7


                     (2) Each share of the Mandatorily Convertible Junior
           Preferred Stock, Series B shall be convertible at any time prior to
           the Mandatory Conversion Date at the option of the holder thereof
           into fully paid and non-assessable shares of Common Stock (the
           "Common Shares," subject to subparagraph (10)) of the Corporation at
           the conversion rate, determined as hereinafter provided, in effect
           at the time of conversion. The rate at which Common Shares shall be
           delivered upon conversion of shares of the Mandatorily Convertible
           Junior Preferred Stock, Series B (herein called the "Conversion
           Rate") shall be initially 200 Common Shares for each share of
           Mandatorily Convertible Junior Preferred Stock, Series B. The
           Conversion Rate shall be subject to adjustment as provided for
           below. Upon conversion, no payment, allowance or adjustment shall be
           made for accumulated and unpaid dividends, whether or not in
           arrears, on the converted shares of Mandatorily Convertible Junior
           Preferred Stock, Series B.

                     (3) In order to convert shares of the Mandatorily
           Convertible Junior Preferred Stock, Series B into Common Shares, the
           holder thereof (a) shall surrender at the office of the transfer
           agent for the Mandatorily Convertible Junior Preferred Stock, Series
           B the certificate or certificates therefor if such shares are
           certificated, duly endorsed to the Corporation or in blank or
           accompanied by appropriate instruments of transfer to the
           Corporation or in blank, and (b) shall give written notice to the
           Corporation at said office that he elects to convert all or a
           portion of such shares. The shares of the Mandatorily Convertible
           Junior Preferred Stock, Series B so elected to be converted shall be
           deemed to have been converted immediately upon the surrender of the
           certificate or certificates for such shares (if such shares are
           certificated) for conversion and the giving of such notice of
           election in accordance with the foregoing provisions (the date of
           each such conversion being a "Conversion Date"), and the person or
           persons entitled to receive the Common Shares issuable upon such
           conversion shall be treated for all purposes as the record holder or
           holders of such Common Shares at such time. If less than all the
           shares are elected to be converted, the holder of such Mandatorily
           Convertible Junior Preferred Stock, Series B may give one or more
           subsequent notices to the Corporation at said office that he elects
           to convert a further portion (or all) of the remaining shares of
           Mandatorily Convertible Junior Preferred Stock, Series B. If such
           holder gives written notice to the Corporation at said office that
           he does not intend to convert all of the shares of Mandatorily
           Convertible Junior Preferred Stock, Series B, the Corporation, if
           requested in writing by such holder, shall, as promptly as
           practicable, issue him a new certificate for the shares remaining
           unconverted. As promptly as practicable after the Conversion Date,
           the Corporation shall issue and deliver at said office the
           certificate or certificates for the number of full Common Shares
           issuable upon such conversion, and shall deliver a cash payment in
           lieu of any fraction of a Common Share, as hereinafter provided, to
           the person or persons entitled to receive the same or to the nominee
           or nominees of such person or persons.

                     (4)  The Conversion Rate shall be adjusted from time to
           time as follows:


                                     7
<PAGE>   8


                               (a) In case the Corporation shall (i) pay a
           dividend on its Common Shares in other Common Shares, (ii) subdivide
           its outstanding Common Shares, (iii) combine its outstanding Common
           Shares into a smaller number of Common Shares, or (iv) issue by
           reclassification of its Common Shares any other Common Shares
           (including in connection with a merger in which the Corporation is a
           surviving corporation), the Conversion Rate in effect at the time of
           the record date for such dividend or the effective date of such
           subdivision, combination or reclassification shall be
           proportionately adjusted, and the shares issuable upon conversion
           shall be modified, so that the holder of each share of the
           Mandatorily Convertible Junior Preferred Stock, Series B converted
           after such time shall be entitled to receive the aggregate number
           and kind of shares which, if such share of the Mandatorily
           Convertible Junior Preferred Stock, Series B had been converted
           immediately prior to such time, the holder would have owned upon
           such conversion and been entitled to receive by virtue of such
           dividend, subdivision, combination or reclassification. Such
           adjustment shall be made successively whenever any of the events
           listed above shall occur.

                               (b) In case the Corporation shall issue rights
           or warrants to the holders of its Common Shares as such entitling
           them (for a period, except in the case of Rights, expiring within 45
           days after the record date for determination of the shareholders
           entitled to receive such rights or warrants) to subscribe for or
           purchase Common Shares at a price per Common Share less than the
           current market price per Common Share (as defined in subparagraph
           (4) below) on such record date, then in each such case the
           Conversion Rate shall be adjusted by multiplying the Conversion Rate
           in effect immediately prior to such record date by a fraction, of
           which the numerator shall be the number of Common Shares outstanding
           on the date of issuance of such rights or warrants plus the number
           of additional Common Shares offered for subscription or purchase,
           and of which the denominator shall be the number of Common Shares
           outstanding on the date of issuance of such rights or warrants plus
           the quotient of the aggregate purchase price for all the Common
           Shares which may be purchased upon exercise of such rights and
           warrants divided by the current market price per Common Share. For
           the purposes of this clause (b): (i) Rights shall not be deemed to
           have been issued, and the record date therefor shall not be deemed
           to have occurred, until the occurrence of the earliest Trigger
           Event, if any, to occur; and (ii) the issuance of rights or warrants
           to subscribe for or purchase securities convertible into Common
           Shares shall be deemed to be the issuance of rights or warrants to
           purchase the Common Shares into which such securities are
           convertible at an aggregate offering price equal to the aggregate
           offering price of such securities plus the minimum aggregate amount
           (if any) payable upon conversion of such securities into Common
           Shares. Such adjustment shall become effective at the opening of
           business on the Business Day next following the record date for such
           rights or warrants. To the extent that Common Shares are not
           delivered after the expiration of such rights or warrants, the
           Conversion Rate shall be readjusted to the Conversion Rate which
           would then be in effect had the adjustment made upon the issuance of
           such rights or warrants been made upon the basis of the issuance of
           rights or warrants in respect of only the number of Common Shares
           actually issued upon exercise of such rights or warrants or upon
           conversion of the convertible securities issued upon exercise of
           such rights or warrants (as the case may be).

                               (c) If the Corporation shall pay a dividend or
           make a distribution to all holders of its Common Shares consisting
           of evidences of its indebtedness or other assets (including capital
           shares of the Corporation other than Common Shares but excluding any
           Ordinary Cash Dividends (as defined below)), or shall issue to all
           holders of its Common Shares rights or warrants to subscribe for or
           purchase any of its securities (other than those referred to in
           clause (b) above), then in each such case the Conversion Rate shall
           be adjusted by multiplying the Conversion Rate in effect on the
           record date for such dividend or distribution or the determination
           of shareholders entitled to receive such dividend or distribution or
           rights or warrants, as the case may be, by a fraction, of which the
           numerator shall be the current market price per Common Share
           (determined pursuant to subparagraph (4) below) on such record date,
           and of which the denominator shall be such current market price per
           Common Share less the fair market value as of such record date of
           the portion of the assets or evidences of indebtedness so
           distributed, or of such subscription rights or warrants, applicable
           to one Common Share. Such adjustment shall become effective on the
           opening of business on the Business Day next following the record
           date for such dividend or distribution or the determination of
           shareholders entitled to receive such dividend or distribution or
           rights or warrants, as the case may be. "Ordinary Cash Dividends"
           shall mean (i) any regular cash dividend on the Common Shares that
           does not exceed the per share amount of the immediately preceding
           regular cash dividend on the Common Shares (as adjusted to
           appropriately reflect any of the events referred to in this
           subparagraph (3)) and (ii) any other cash dividend or distribution
           which, when combined on a per share basis with the per share amount
           of all other cash dividends and distributions paid on the Common
           Shares during the 365-day period ending on the date of declaration
           of such dividend or distribution (as adjusted to appropriately
           reflect any of the events referred to in this subparagraph (3) and
           excluding cash dividends or distributions that resulted in an
           adjustment to the Conversion Price), does not exceed 10% of the
           current market price per Common Share (determined pursuant to
           subparagraph (4)) on the Trading Day immediately preceding the date
           of declaration of such dividend or distribution.

                     (5) For the purpose of any computation under subparagraph
           (4) above, the "current market price per Common Share" on any date
           in question shall be deemed to be the average of the daily Closing
           Prices for the five consecutive Trading Days ending on the earlier
           of the day in question and, if applicable, the day before the "ex"
           date with respect to the issuance or distribution requiring such
           computation; provided, however, that if another event occurs that
           would require an adjustment pursuant to subparagraph (4), the Board
           of Directors of the Corporation may make such adjustments to the
           Closing Prices during such five Trading Day period as it reasonably
           deems appropriate to effectuate the intent of the adjustments in
           subparagraph (4), in which case any such determination by the Board
           of Directors of the Corporation shall be set forth in a Board
           resolution and shall be conclusive absent manifest error. For
           purposes of this paragraph, the term "ex" date, when used with


                                     9
<PAGE>   10
           respect to any issuance or distribution, means the first date on
           which the Common Stock trades in a regular way on the relevant
           exchange or in the relevant market from which the Closing Prices
           were obtained without the right to receive such issuance or
           distribution. For the purpose of any computation under subparagraph
           (3) above, the "fair market value" of any assets, evidences of
           indebtedness, subscription rights or warrants on any date in
           question: (i) in the event any such item is a publicly traded
           security, shall be determined for such date pursuant to the
           provisions of this subparagraph (5) for determination of the
           "current market price per Common Share," except that (x) each
           reference therein to "Common Share" or "Common Stock" shall be
           deemed to mean such other publicly traded security, and (y) if such
           security shall not trade on a "when issued" basis for the five
           consecutive Trading Days preceding the "ex" date, such determination
           shall be made for the period of five consecutive Trading Days
           commencing on the "ex" date; and (ii) in the event any such item is
           not a publicly traded security, shall be reasonably determined for
           such date by the Board of Directors of the Corporation, as evidenced
           by a resolution of the Board, whose determination shall be
           conclusive absent manifest error. For the purpose of subparagraph
           (4) and this subparagraph (5):

                               (a) "Closing  Price" means the daily closing
           price of a Common Share as reported by Bloomberg L.P. for the
           Principal Market for the Common Shares or, if such price is not so
           reported by Bloomberg L.P., as reported by another recognized
           source selected by the Board of Directors.

                               (b) "Trading Day" means a day on which each of
           the (a) New York Stock Exchange, (b) Chicago Board Options Exchange,
           and (c) Principal Markets with respect to the Common Shares are
           regularly scheduled to be open for trading. For purposes of this
           definition, a day on which any such exchange is scheduled to close
           (as opposed to unexpectedly closing) prior to its regular closing
           time shall not constitute a Trading Day.

                               (c) "Principal Market" means the principal
           exchange on which the Common Shares are traded or the principal
           market on which the Common Shares are quoted, as determined by the
           Board of Directors.

                     (6) In any case of any reclassification of Common Shares
           (other than a reclassification of the Common Shares referred to in
           subparagraph 4(a)), any consolidation or merger of the Corporation
           with or into another corporation or other entity (other than a
           merger resulting in a reclassification of the Common Shares referred
           to in subparagraph 4(a) hereof) or any sale or conveyance to another
           corporation (other than a wholly-owned subsidiary of the
           Corporation) of all or substantially all of the property of the
           Corporation, the holder of a share of the Mandatorily Convertible
           Junior Preferred Stock, Series B shall have the right thereafter to
           convert such share into the kind and amount of shares of stock and
           other securities and property receivable upon such reclassification,
           consolidation, merger, sale or conveyance by a holder of the number
           of Common Shares into which such share of the Mandatorily
           Convertible Junior Preferred Stock, Series B might have been
           converted immediately prior to such reclassification, consolidation,
           merger, sale or conveyance (assuming that such holder of Common
           Shares failed to exercise rights of election, if any, as to the kind
           or amount of shares of stock, other securities, cash, or other
           property receivable upon consummation of such transaction (provided
           that, if the kind or amount of shares of stock, other securities,
           cash, or other property receivable upon consummation of such
           transaction is not the same for each non-electing share, then the

                                      10

<PAGE>   11
           kind and amount of shares of stock, other securities, cash or other
           property receivable upon consummation of such transaction for each
           non-electing share shall be deemed to be the kind and amount so
           receivable per share by a plurality of the non-electing shares)) and
           shall have no other conversion rights with regard to such share of
           Mandatorily Convertible Junior Preferred Stock, Series B. In the
           event of such a reclassification, consolidation, merger, sale or
           conveyance, effective provision shall be made in the certificate of
           incorporation or similar document of the resulting or surviving
           corporation or otherwise so that the conversion rate applicable to
           any stock or other securities or property into which the shares of
           the Mandatorily Convertible Junior Preferred Stock, Series B shall
           then be convertible shall be subject to adjustment from time to time
           in a manner and on terms as nearly equivalent as practicable to the
           provisions with respect to the Common Shares contained in clauses
           (a) to (c) of subparagraph (4) inclusive, above, and the other
           provisions of this paragraph F with respect to the Common Shares
           shall apply on terms as nearly equivalent as practicable to any such
           other shares of stock and other securities and property deliverable
           upon conversion of shares of Mandatorily Convertible Junior
           Preferred Stock, Series B.

                     (7) In the event that any time, as a result of any
           adjustment made pursuant to clause (a) of subparagraph (4) above,
           the holder of any shares of the Series B Junior Voting Convertible
           Preferred Stock thereafter surrendered for conversion shall become
           entitled to receive any shares of capital stock of the Corporation
           other than Common Shares, thereafter the number of such other shares
           so receivable upon conversion of such shares of Mandatorily
           Convertible Junior Preferred Stock, Series B shall be subject to
           adjustment from time to time in a manner and on terms as nearly
           equivalent as practicable to the provision with respect to the
           Common Shares contained in clauses (a) to (c) of subparagraph (4)
           inclusive, above, and the other provisions of this paragraph F with
           respect to the Common Shares shall apply to any such other shares.

                     (8) Whenever any adjustments are required in the Common
           Shares into which each share of Mandatorily Convertible Junior
           Preferred Stock, Series B is convertible, the Corporation shall
           forthwith (a) file with the transfer agent of the Mandatorily
           Convertible Junior Preferred Stock, Series B a statement describing
           in reasonable detail the adjustment and the method of calculation
           used and (b) cause a copy of such statement to be mailed to each
           holder of record of the Mandatorily Convertible Junior Preferred
           Stock, Series B as of the effective date of such adjustment.

                     (9) The Corporation shall at all times reserve and keep
           available out of its authorized but unissued Common Shares for the
           purpose of issuance upon conversion of the Mandatorily Convertible
           Junior Preferred Stock, Series B the full number of Common Shares
           then issuable upon the conversion of all outstanding shares of the
           Mandatorily Convertible Junior Preferred Stock, Series B.

                     (10) The Corporation will pay any and all taxes that may
           be payable in respect of the issuance or delivery of Common Shares
           on conversion of shares of the Mandatorily Convertible Junior
           Preferred Stock, Series B pursuant hereto. The Corporation shall
           not, however, be required to pay any tax which may be payable in
           respect of any transfer involving issue and delivery of Common
           Shares in the name other than that which the shares of Mandatorily
           Convertible Junior Preferred Stock, Series B so converted were
           registered and no such issue and delivery shall be made unless and
           until the person requesting such issue has paid to the Corporation
           the amount of any such tax, or has established, to the satisfaction
           of the Corporation, that such tax has been paid.

                                      11
<PAGE>   12


                     (11) For the purpose of this paragraph F, the term "Common
           Shares" shall include any shares of the Corporation of any class or
           series which has no preference or priority in the payment of
           dividends or in the distribution of assets upon any voluntary or
           involuntary liquidation, dissolution or winding up of the
           Corporation and which is not subject to redemption by the
           Corporation. However, Common Shares issuable upon conversion of the
           Mandatorily Convertible Junior Preferred Stock, Series B shall
           include only shares of the class designated as Common Shares as of
           the original date of issuance of the Mandatorily Convertible Junior
           Preferred Stock, Series B, or shares of the Corporation of any
           classes or series resulting from any reclassification or
           reclassifications thereof and which have no preference or priority
           in the payment of dividends or in the distribution of assets upon
           any voluntary or involuntary liquidation, dissolution or winding up
           of the Corporation and which are not subject to redemption by the
           Corporation, provided that if at any time there shall be more than
           one such resulting class or series, the shares of such class and
           series then so issuable shall be substantially in the proportion
           which the total number of shares of such class and series resulting
           from all such reclassifications bears to the total number of shares
           of all classes and series resulting from all such reclassifications.

                     (12) No fractional shares or scrip representing fractional
           shares shall be issued upon the conversion of the Mandatorily
           Convertible Junior Preferred Stock, Series B. If any such conversion
           would otherwise require the issuance of a fractional share, an
           amount equal to such fraction multiplied by the Closing Price
           (determined as provided in subparagraph F(4) above) of the Common
           Shares on the date of conversion shall be paid to the holder in cash
           by the Corporation. If on such date there is no Closing Price, the
           fair value of a Common Share on such date, as reasonably determined
           by the Board of Directors of the Corporation as set forth in a
           resolution of such Board of Directors, shall be used.

                     (13) All shares of the Mandatorily Convertible Junior
           Preferred Stock, Series B purchased or otherwise acquired by the
           Corporation (including shares surrendered for conversion) shall be
           canceled and thereupon restored to the status of authorized but
           unissued shares of Preferred Stock undesignated as to series.

                     (14) No adjustment in the Conversion Rate shall be
           required unless such adjustment (plus any adjustments not previously
           made by reason of this subparagraph (14)) would require an increase
           or decrease of at least 1% in the number of Common Shares into which
           each share of the Series B Junior Convertible Preferred Stock is
           then convertible; provided, however, that any adjustments which by
           reason of this subparagraph (14) are not required to be made shall
           be carried forward and taken into account in any subsequent
           adjustment. All calculations under this paragraph F shall be made to
           the nearest one-thousandth of a share.


                                      12
<PAGE>   13


                     (15) The Board of Directors may make such upward
           adjustments in the Conversion Rate, in addition to those required by
           this paragraph F, as shall be determined by the Board, as evidenced
           by a Board resolution, to be advisable in order to avoid taxation so
           far as practicable of any dividend of stock rights or any event
           treated as such for Federal income tax purposes to the recipients.
           The determination of the Board of Directors as to whether an
           adjustment should be made pursuant to the provisions of this
           subparagraph (15), and if so, as to what adjustment should be made
           and when, shall be conclusive, final and binding on the Corporation
           and all stockholders of the Corporation.

                     (16) Notwithstanding the foregoing provisions of this
           paragraph F, no adjustment of the Conversion Rate shall be required
           to be made upon the issuance of any shares of Common Stock pursuant
           to any present or future plan providing for the reinvestment of
           dividends or interest payable on securities of the Corporation and
           the investment of additional optional amounts in shares of Common
           Stock under any such plan.

                     (17) Notwithstanding any other provision of this paragraph
           F, the issuance or distribution of Rights shall not be deemed to
           constitute an issuance or a distribution or dividend of rights,
           warrants, or other securities to which any of the adjustment
           provisions described above applies until the occurrence of the
           earliest Trigger Event.

                     (18) For purposes of this paragraph F, shares of Common
           Stock owned by, or held for the account of, the Corporation or
           another entity of which a majority of the capital stock or equity
           interests having ordinary voting power are owned, directly or
           indirectly, by the Corporation shall be deemed to be not
           outstanding.

           G.   Voting Rights. The holders of Mandatorily Convertible Junior
Preferred Stock, Series B shall have no right to vote except as otherwise
specifically  provided herein, in the Articles of Incorporation, as amended,
of the Corporation, or as required by statute.

                     (1) So long as any shares of Mandatorily Convertible
           Junior Preferred Stock, Series B are outstanding, in addition to any
           other vote or consent of shareholders required in the Articles of
           Incorporation or by law, the consent of the holders of at least a
           majority of the Mandatorily Convertible Junior Preferred Stock,
           Series B and all other shares of parity stock, if any, at the time
           outstanding that would be affected similarly by the action described
           in clauses (a)-(d) below and that are entitled to vote on such
           matter, given in person or by proxy, either in writing without a
           meeting (if permitted by law) or by vote at any meeting called for
           the purpose, shall be necessary for effecting or validating:


                                      13
<PAGE>   14
                               (a) any amendment, alteration or repeal of any
           of the provisions of the Articles of Incorporation of the
           Corporation, which affects adversely the voting powers, rights or
           preferences of the holders of the Mandatorily Convertible Junior
           Preferred Stock, Series B; provided, that the amendment of the
           provisions of the Articles of Incorporation so as to authorize or
           create, or to increase the authorized amount of, any senior or
           junior stock or to issue additional shares of the Mandatorily
           Convertible Junior Preferred Stock, Series B as required by the
           Share Settlement Agreement shall not be deemed to affect adversely
           the voting powers, rights or preferences of the holders of the
           Mandatorily Convertible Junior Preferred Stock, Series B;

                               (b) the sale, lease or conveyance by the
           Corporation of all or substantially all of its property or assets;

                               (c) the authorization, creation or issuance of,
           or the increase in the authorized amount of, any stock of any class
           or series, or any security convertible into stock of any class or
           series, ranking on a parity with the Mandatorily Convertible Junior
           Preferred Stock, Series B (other than the issuance of additional
           shares of the Mandatorily Convertible Junior Preferred Stock, Series
           B as required by the Share Settlement Agreement); or

                               (d) the merger or consolidation of the
           Corporation with or into any other corporation or other entity,
           unless each holder of shares of Mandatorily Convertible Junior
           Preferred Stock, Series B immediately preceding such merger or
           consolidation shall receive or continue to hold in the surviving or
           resulting corporation or other entity the same number of shares,
           with substantially the same rights and preferences (except as
           contemplated by subparagraph F(6) and except for those rights and
           preferences that could be affected without the vote of the holders
           of the Mandatorily Convertible Junior Preferred Stock, Series B,
           such as the authorization and issuance of senior stock), as
           correspond to the shares of Mandatorily Convertible Junior Preferred
           Stock, Series B held immediately prior to such merger or
           consolidation.

                     (2) (a) In the event that full cumulative dividends on the
           Mandatorily Convertible Junior Preferred Stock, Series B are not
           paid for six consecutive Dividend Periods, the number of directors
           of the Corporation constituting the entire Board of Directors shall
           be increased by two persons and the holders of shares of the
           Mandatorily Convertible Junior Preferred Stock, Series B, voting
           separately as a class together with the holders of shares of all
           other series of capital stock of the Corporation ranking on a parity
           with the Mandatorily Convertible Junior Preferred Stock, Series B as
           to the payment of dividends and having the then present right to
           elect one or more directors as a result of a dividend arrearage but

           provisions for the vesting of such voting rights in the case of any
           similar future arrearages in dividends), and the terms of office of
           all persons previously elected as directors by the holders of shares

           such other Class Voting Stock shall forthwith terminate and the
           number of the Board of Directors shall be reduced accordingly.

                               (b) At any time after the voting power referred
           to in subparagraph 2(a) above shall have been so vested in the

           Stock, Series B, the Secretary of the Corporation may, and upon the
           written request of any holder or the holders of at least 10% of the
           number of shares of Mandatorily Convertible Junior Preferred Stock,
           Series B then outstanding (addressed to the Secretary at the
           principal executive office of the Corporation) shall, call a special
           meeting of the holders of shares of the Mandatorily Convertible
           Junior Preferred Stock, Series B and all other Class Voting Stock
           for the election of the directors to be elected by them pursuant to
           subparagraph 2(a); provided that the Secretary shall not be required
           to call such special meeting if the request for such meeting is
           received less than 45 calendar days before the date fixed for the
           next ensuing annual meeting of shareholders. Such call shall be made
           by notice similar to that provided in the bylaws of the Corporation
           for a special meeting of the shareholders or as required by law.
           Subject to the foregoing provisions, if any such special meeting
           required to be called as above provided shall not be called by the
           Secretary within 20 calendar days after receipt of an appropriate
           request, then any holder of shares of Mandatorily Convertible Junior
           Preferred Stock, Series B may call such meeting, upon the notice
           above provided, and for that purpose shall have access to the stock
           books and records of the Corporation. Except as otherwise provided
           by law, at any such meeting, the holders of a majority of the number
           of shares of Mandatorily Convertible Junior Preferred Stock, Series
           B and such other Class Voting Stock then outstanding shall
           constitute a quorum for the purpose of electing directors as
           contemplated in subparagraph 2(a) above. If at any such meeting or
           adjournment thereof a quorum of such holders of Mandatorily
           Convertible Junior Preferred Stock, Series B and such other Class
           Voting Stock shall not be present, no election of directors by the
           Mandatorily Convertible Junior Preferred Stock, Series B and such
           other Class Voting Stock shall take place, and any such meeting may
           be adjourned from time to time for periods not exceeding 30 calendar
           days until a quorum of the Mandatorily Convertible Junior Preferred
           Stock, Series B and the Class Voting Stock is present at such
           adjourned meeting. Unless otherwise provided by law or the Articles
           of Incorporation, as amended, directors to be elected by the holders
           of shares of Mandatorily Convertible Junior Preferred Stock, Series
           B and such other Class Voting Stock shall be elected by a plurality
           of the votes cast by such holders at a meeting at which a quorum is
           present. Notwithstanding the foregoing, the absence of a quorum of
           the Mandatorily Convertible Junior Preferred Stock, Series B and
           such other Class Voting Stock shall not prevent the voting of,
           including the election of, directors by the holders of Common Stock
           and other classes of capital stock at such meeting.

           holders of shares of Mandatorily Convertible Junior Preferred Stock,
           Series B and the other series, if any, of Class Voting Stock. In
           case any vacancy (other than as provided in the preceding sentence)
           shall occur among the directors elected by the holders of shares of
           the Mandatorily Convertible Junior Preferred Stock, Series B (and
           such other Class Voting Stock), a successor shall be elected by the

Enron Corp.
1400 Smith Street
Houston, Texas  77002

Gentlemen:

         As Executive Vice President and General Counsel of Enron Corp., an
Oregon corporation ("Enron"), I am familiar with Post-Effective Amendment No. 1
to Registration Statement No. 333-70465 of Enron on Form S-3 (the "Registration
Statement") relating to the registration of an additional 7.5 million shares of
Enron Corp. Common Stock, and the proposed offering from time to time of (i) up
to an aggregate amount of $500,000,000 of Enron Debt Securities, Enron Preferred
Stock and Depositary Shares, and (ii) up to 15 million shares of Enron Common
Stock, no par value (the Debt Securities, Preferred Stock, Depositary Shares and
Common Stock collectively referred to herein as the "Securities"). In connection
therewith, I have examined, among other things, a copy of the Amended and
Restated Articles of Incorporation and Bylaws of Enron, the corporate
proceedings taken to date with respect to the authorization, issuance and sale
of the Securities, a copy of the Indenture dated as of November 1, 1985, as
supplemented (the "Indenture"), between Enron and Harris Trust and Savings Bank,
Trustee, and the forms of certain other agreements to be entered into by Enron,
and I have performed such other investigations as I have considered appropriate
as the basis for the opinions expressed herein. Capitalized terms used but not
defined herein are used as defined in the Registration Statement.

         Based on the foregoing, I am of the opinion that:

         (1) Enron is a corporation duly organized, validly existing and in good
standing under the laws of the State of Oregon.

         (2) The Debt Securities of Enron have been validly authorized for
issuance, and (subject to the Registration Statement becoming effective and any
applicable state securities or Blue Sky laws being complied with), when the
terms thereof and their issue and sale have been duly established, upon issuance
and delivery thereof as set forth in the Registration Statement, and upon
receipt by Enron of the purchase price thereof, the Debt Securities will be
validly issued and will be binding obligations of Enron.


<PAGE>   2


         (3) When (a) the terms of the series of Preferred Stock and their issue
and sale have been duly established, and (if applicable) a deposit agreement has
been duly authorized, executed and delivered by Enron and a Depositary, in each
case in conformity with Enron's Amended and Restated Articles of Incorporation
and Oregon law, (b) a certificate of designations with respect to such series of
the Preferred Stock has been duly filed with the Secretary of State of the State
of Oregon, (c) the Registration Statement has become effective and any
applicable state securities or Blue Sky laws have been complied with, (d) the
shares of such series have been issued, and (if applicable) Depositary Receipts
have been delivered as set forth in the Registration Statement, and (e) Enron
has received the purchase price of such shares in accordance with the terms of
their issue and sale, the shares of such series of Preferred Stock and (if
applicable) the related Depositary Shares will be validly issued, fully paid and
nonassessable.

         (4) The issuance of the Common Stock to be issued by Enron has been
duly authorized, and (subject to the Registration Statement becoming effective
and applicable Blue Sky laws being complied with), when the terms of their issue
and sale have been duly established, upon the issuance and delivery thereof as
set forth in the Registration Statement, and upon the receipt by Enron of the
purchase price thereof, the Common Stock will be validly issued, fully paid and
nonassessable.

         I am a member of the bar of the State of Texas. The opinion set forth
above is limited in all respects to the laws of the State of Texas, the Oregon
Business Corporation Act and federal law.

         I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to me under the caption "Validity
of Securities" in the Prospectus constituting part of the Registration Statement
and to the filing of this opinion as an exhibit thereto. By giving such consent
I do not admit that I am an expert with respect to any part of the Registration
Statement, including this exhibit, within the meaning of the term "expert" as
used in the Securities Act of 1933, as amended, or the rules and regulations of
the Securities and Exchange Commission issued thereunder.

                                                       Very truly yours,

                                                       /s/ JAMES V. DERRICK, JR.
