(1)   The shares of common stock, no par value ("Enron Common Stock"), of Enron
      Corp., an Oregon corporation ("Enron"), covered by this item may be issued
      in exchange for shares of Series A Preferred Stock ("Series A Preferred")
      of Northern Natural Gas Company, a Delaware corporation ("Northern
      Natural") and an indirect wholly owned subsidiary of Enron, pursuant to an
      exchange agreement (the "Exchange Agreement") dated as of November 9, 2001
      between Dynegy and Enron that is described in Item 4 of this Schedule 13D.
      The number of shares of Enron Common Stock for which each share of


                                       2


      Series A Preferred may be exchanged is subject to an anti-dilution
      adjustment more fully described in response to Item 4. Prior to the
      exchange, Dynegy is not entitled to any rights as a holder of Enron Common
      Stock with respect to the shares of Enron Common Stock subject to the
      exchange. The exchange can only take place upon the occurrence of certain
      events described in Item 4, none of which has occurred as of the date
      hereof, and accordingly Dynegy has no present investment or dispositive
      power with respect to such shares. If the exchange takes place, Dynegy
      will have the sole right to vote or to dispose of the shares of Enron
      Common Stock issued as a result of such exchange.

(2)   Beneficial ownership percentages set forth herein assume that there were
      743,905,381 shares of Enron Common Stock outstanding prior to the deemed
      exchange of Series A Preferred for Enron Common Stock and are based on
      information furnished by Enron. Pursuant to Rule 13d-3 under the
      Securities Exchange Act of 1934, as amended, shares of Enron Common Stock
      deemed to be beneficially owned by the reporting person as a result of the
      exchange are also deemed to be outstanding for purposes of computing these
      percentages.



                                       3


                           SCHEDULE 13D OF DYNEGY INC.

ITEM 1.     SECURITY AND ISSUER.

      This Statement on Schedule 13D relates to the common stock, no par value
("Enron Common Stock"), of Enron Corp., an Oregon corporation ("Enron"). The
address of Enron's principal executive office is 1400 Smith Street, Houston,
Texas 77002.

ITEM 2.     IDENTITY AND BACKGROUND.

      Dynegy Inc. ("Dynegy"), the reporting person, is a leading provider of
energy and communications solutions to customers around the globe, and is
incorporated under the laws of the state of Illinois. Dynegy's principal
business address and principal office address is 1000 Louisiana, Suite 5800,
Houston, Texas 77002.

      (a) - (c); (f) ANNEX A attached hereto (which is incorporated herein by
reference) contains a list of the directors and executive officers of Dynegy and
includes the following information with respect to each director and executive
officer of Dynegy:

      (1)   name;

      (2)   business address;

      (3)   present principal occupation or employment and the name, principal
            business and address of any corporation or other organization in
            which such employment is conducted; and

      (4)   citizenship.

There is no corporation or other person ultimately controlling Dynegy. Chevron
U.S.A. Inc., a Pennsylvania corporation and a subsidiary of ChevronTexaco
Corporation, a Delaware corporation, owns 86,499,914 shares of Class B Common
Stock of Dynegy (all shares of that class), which is equal to approximately 27%
of the combined Class A and Class B Common Stock of Dynegy, and has entered into
a series of agreements with Dynegy and Enron in connection with the execution of
the Merger Agreement. Those agreements are more fully described in response to
Item 4 hereof.

      (d) - (e) During the last five years, neither Dynegy, nor, to the
knowledge of Dynegy, any of the persons listed on ANNEX A hereto, (i) has been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction and as a result of such proceeding
was or is subject to a judgment, decree or final order enjoining future
violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

ITEM 3.     SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      As more fully described in Item 4 hereof under "Chevron Investments," the
proceeds of the purchase by Chevron U.S.A. Inc. of Series B Preferred Stock of
Dynegy is the source of the funds used by Dynegy to purchase the Series A
Preferred (as defined in Item 4 hereof under "Equity Investment") from Northern
Natural Gas Company, a Delaware corporation and indirect wholly owned subsidiary
of Enron ("Northern Natural"). Dynegy did not pay any cash consideration in
respect of the Exchange


                                       4


Agreement and has not exchanged any shares of Series A Preferred for shares of
Enron Common Stock thereunder.

      No additional payment would be required to effect the exchange.

ITEM 4.     PURPOSE OF TRANSACTION.

      (a)-(c)

MERGER AGREEMENT

      On November 9, 2001, Dynegy, Stanford, Inc., a Delaware corporation and
wholly owned subsidiary of Dynegy ("Newco"), Sorin, Inc., an Oregon corporation
and wholly owned subsidiary of Newco ("Enron Merger Sub"), Badin, Inc., an
Illinois corporation and wholly owned subsidiary of Newco ("Dynegy Merger Sub"),
and Enron entered into an Agreement and Plan of Merger (the "Merger Agreement"),
whereby, subject to the conditions stated therein, (i) Enron Merger Sub will
merge with and into Enron, with Enron surviving as a wholly owned subsidiary of
Newco (the "Enron Merger"), and (ii) Dynegy Merger Sub will merge with and into
Dynegy, with Dynegy surviving as a wholly owned subsidiary of Newco
(collectively with the Enron Merger, the "Mergers"). At the effective time of
the Mergers, (1) each issued and outstanding share of common stock, no par
value, of Enron will be converted into 0.2685 shares (the "Enron Merger Ratio")
of Class A common stock, par value $0.01 per share, of Newco ("Newco Class A
Common Stock"), and (2) each issued and outstanding share of Class A common
stock, no par value, of Dynegy and each outstanding share of Class B common
stock, no par value, of Dynegy will be converted into one share of Newco Class A
Common Stock and one share of Class B common stock, par value $0.01 per share,
of Newco, respectively.

      Under the Merger Agreement, Enron is entitled to issue up to $2 billion of
additional equity securities prior to consummation of the Mergers. However, the
Enron Merger Ratio is subject to downward adjustment if Enron issues equity
securities at an equivalent Enron Common Stock price that is less than the
product of (1) the existing Enron Merger Ratio and (2) the last reported price
of Dynegy Class A common stock as reported on the New York Stock Exchange on the
day that a price is determined pursuant to a binding agreement for such
issuance.

      The Merger Agreement provides that the parties will cooperate with each
other in analyzing and determining a structure that results in a single
corporation with substantially all the senior debt (other than that of regulated
utility subsidiaries) of Dynegy, Dynegy Holdings Inc., a subsidiary of Dynegy,
and Enron, and will promptly execute an appropriate amendment to the Merger
Agreement to reflect such structure.

      The closing of the Mergers will occur on the first business day
immediately following the day on which all of the conditions to the Mergers
contained in the Merger Agreement have been fulfilled or waived or on such other
date as Dynegy and Enron may agree, but in no event prior to the expiration of a
period of six months after the initial purchase of shares of Dynegy Series B
Preferred Stock by ChevronTexaco Corporation as described below. The closing of
the Mergers is conditioned upon the approval of the shareholders of both Dynegy
and Enron, the receipt of applicable regulatory approvals, including the
expiration or termination of the waiting period prescribed by the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other
customary conditions, including the absence of any events or series of events
that has had or is reasonably likely to have a material adverse effect on Enron
or Dynegy, excluding the effects of general economic and industry conditions,
all as further described in the Merger Agreement. Under the Merger Agreement, if
Enron's liabilities and expenses from and after November 9, 2001 associated with
all pending or threatened litigation matters, in the reasonable judgment of
Dynegy exercised in good faith after consultation with outside counsel
experienced in such types of litigation, exceed, or are reasonably likely to
exceed, $2 billion in the aggregate (net of proceeds of insurance and litigation
reserves reflected in Enron's financial statements),


                                       5


the amount of such excess over $2 billion will be taken into account in
determining whether a material adverse effect on Enron has occurred, and, in any
event, if the amount of such excess exceeds, or is reasonably likely to exceed,
$1.5 billion, a material adverse effect on Enron will be deemed to have
occurred. The Merger Agreement provides that Dynegy or Enron may be required to
pay a termination fee of $350 million to the other party under certain
circumstances relating to competing transactions or a change in the
recommendation of the party's board to its shareholders.

      In connection with the execution and delivery of the Merger Agreement,
each of Chevron U.S.A. Inc., the holder of approximately 27% of the outstanding
Dynegy common stock, and Charles L. Watson, the Chairman of the Board and Chief
Executive Officer of Dynegy, have entered into a Shareholder Agreement with
Enron, pursuant to which each has agreed to vote its or his shares of Dynegy
common stock in favor of the transactions contemplated by the Merger Agreement
and to refrain from soliciting a competing transaction to the Mergers.

EXHIBITS AND INCORPORATION BY REFERENCE.

      The Merger Agreement and the two Shareholder Agreements are filed herewith
as Exhibits 1.1, 2 and 3, respectively, and are incorporated in this Schedule
13D by reference. The foregoing description of the Merger Agreement and the
Shareholder Agreements, and the transactions contemplated in such documents, is
qualified in its entirety by reference to such documents.

EQUITY INVESTMENT

      PREFERRED STOCK PURCHASE. In connection with the Merger Agreement, Dynegy
entered into a Subscription Agreement (the "Subscription Agreement") with Enron
and Northern Natural, pursuant to which Dynegy purchased 1,000 shares of
Northern Natural's Series A Preferred Stock, par value $.01 per share ("Series A
Preferred"), for $1.5 billion on November 13, 2001.

      The Series A Preferred ranks senior to all common stock of Northern
Natural and is entitled to dividends when, as and if declared by the board of
directors of Northern Natural at a rate of 6%, payable annually beginning on
January 31, 2003, or, at Northern Natural's option, quarterly. In the event of
any liquidation or winding up of Northern Natural, the holders of Series A
Preferred will be entitled to receive in preference to the holders of the common
stock, an amount equal to $1,500,000 per share plus accrued and unpaid
dividends, if any.

      The Series A Preferred is redeemable in whole, but not in part, at the
option of Northern Natural:

      o     for a period of six months from the date the Merger Agreement has
            been terminated by (a) the mutual written consent of Dynegy and
            Enron ("Mutual Consent"); (b) either Dynegy or Enron if the Mergers
            have not been consummated by November 30, 2002 (subject to extension
            in certain cases to May 31, 2003)("Time Expiration Event"); or (c)
            either Dynegy or Enron if a court or governmental agency has issued
            a final, nonappealable order permanently prohibiting the
            transactions contemplated in the Merger Agreement ("Court Order
            Event");

      o     for a period of six months from the third anniversary of the
            termination of the Merger Agreement by (a) Dynegy or Enron if the
            shareholders of Enron do not approve the Mergers at the meeting held
            for that purpose ("Enron Shareholder No Vote"); (b) Enron prior to
            receiving shareholder approval of the Mergers if Enron has received
            an Enron Superior Proposal (as defined in the Merger Agreement) and
            entered into a binding definitive written agreement providing for
            the implementation of the Enron Superior Proposal ("Enron Superior
            Proposal Event"); (c) Dynegy if Enron has breached its
            representation, warranties or covenants in the Merger Agreement
            ("Enron Breach"); or (d) Dynegy if the board of directors of Enron
            has withdrawn or materially modified (in a manner adverse to Dynegy)
            its approval


                                       6


            or recommendation of the Merger Agreement or recommends to its
            shareholders another proposal to acquire Enron ("Enron Board
            Action");

      o     for a period of one year from the date the Merger Agreement has been
            terminated by (a) Enron or Dynegy if the shareholders of Dynegy do
            not approve the Mergers at the meeting held for that purpose
            ("Dynegy Shareholder No Vote"); (b) Dynegy prior to receiving
            shareholder approval of the Mergers if Dynegy has received a Dynegy
            Superior Proposal (as defined in the Merger Agreement) and entered
            into a binding definitive written agreement providing for the
            implementation of the Dynegy Superior Proposal ("Dynegy Superior
            Proposal Event"); or (c) Enron if the board of directors of Dynegy
            has withdrawn or materially modified (in a manner adverse to Enron)
            its approval or recommendation of the Merger Agreement or recommends
            to its shareholders another proposal to acquire Dynegy ("Dynegy
            Board Action"); and

      o     for a period of one year from the date that Enron notifies Dynegy
            that it is terminating the Merger Agreement based on any Dynegy
            breach of its representations, warranties or covenants in the Merger
            Agreement ("Dynegy Breach");

in each case, at a redemption price equal to the liquidation preference amount;
PROVIDED, that on the date of the redemption the board of directors of Northern
Natural declares and pays all accrued and unpaid dividends on the Series A
Preferred.

      Without the approval of the holders of at least a majority of the Series A
Preferred, Northern Natural will not, among other things, issue any capital
stock, sell any assets above a specified threshold, make a voluntary bankruptcy
filing or incur certain indebtedness.

      OPTION AGREEMENT. In connection with the Subscription Agreement, Dynegy
entered into an Option Agreement (the "Option Agreement") with CGNN Holding
Company, Inc., a Delaware corporation and indirect subsidiary of Enron ("CGNN"),
MCTJ Holding Co. LLC, a Delaware limited liability company and a subsidiary of
CGNN ("MCTJ"), Enron and Dynegy Holdings Inc., a Delaware corporation and a
subsidiary of Dynegy ("Dynegy Holdings"), for consideration of $1 million.
Pursuant to the Option Agreement, Dynegy Holdings has the option to purchase all
of the membership interests of MCTJ in certain circumstances. MCTJ indirectly
owns all of the common stock of Northern Natural.

      The exercise price for the option is $23 million, plus the amount by which
Northern Natural's indebtedness under its bank credit facility and senior notes
is less than $950 million (or minus the amount by which such indebtedness
exceeds $950 million), subject to adjustment for the amount of working capital
at the time of the exercise. Dynegy Holdings may exercise the option:

      o     at any time after (collectively, the "Purchase Option Events")

            o     the Merger Agreement has been terminated pursuant to an Enron
                  Shareholder No Vote, an Enron Superior Proposal Event or an
                  Enron Board Action; or

            o     Dynegy has notified Enron that it is terminating the Merger
                  Agreement pursuant to an Enron Breach;

      o     at any time beginning six months plus one day after the Merger
            Agreement has been terminated pursuant to Mutual Consent, a Time
            Expiration Event or a Court Order Event; and

      o     at any time beginning one year after

            o     the Merger Agreement has been terminated pursuant to a Dynegy
                  Shareholder No Vote, a Dynegy Superior Proposal or a Dynegy
                  Board Action; or


                                       7



            o     Enron has notified Dynegy that it is terminating the Merger
                  Agreement pursuant to a Dynegy Breach.

      The option will terminate if (i) the Mergers are consummated, (ii) the
Series A Preferred is exchanged for Enron Common Stock pursuant to the Exchange
Agreement described below or (iii) the Series A Preferred is redeemed in
accordance with its terms.

      PURCHASE OPTION AGREEMENT. In connection with the Subscription Agreement,
Dynegy also entered into a Purchase Option Agreement (the "Purchase Option
Agreement") with CGNN, MCTJ, Northern Natural, Enron and Dynegy Holdings.
Pursuant to the Purchase Option Agreement, if Dynegy Holdings has purchased all
of the membership interests of MCTJ pursuant to the Option Agreement after any
of the Purchase Option Events, CGNN will have the option for 90 days after such
purchase (up to 180 days in some circumstances) to purchase

      o     all of the membership interests of MCTJ for $24 million, plus the
            amount by which Northern Natural's indebtedness under its bank
            credit facility and senior notes is less than $950 million (or minus
            the amount by which such indebtedness exceeds $950 million), plus
            accrued and unpaid dividends on the Series A Preferred through the
            date of the purchase by Dynegy Holdings of the membership interests
            of MCTJ pursuant to the Option Agreement, subject to adjustment for
            changes in working capital and other long-term debt since the
            purchase by Dynegy Holdings of the membership interests of MCTJ
            pursuant to the Option Agreement; and

      o     the Series A Preferred for $1.5 billion.

      EXCHANGE AGREEMENT. In connection with the purchase of the Series A
Preferred, Dynegy entered into an Exchange Agreement (the "Exchange Agreement")
with Enron. Pursuant to the Exchange Agreement, each share of Series A Preferred
is exchangeable for a number of shares of common stock of Enron determined by
dividing the liquidation preference amount, plus all accrued and unpaid
dividends, by $8.86, subject to adjustment based on changes to the Enron Merger
Ratio (as defined in the Merger Agreement) pursuant to the Merger Agreement:

      o     at the option of Dynegy during the 90-day period beginning on the
            date the Merger Agreement is terminated pursuant to an Enron
            Shareholder No Vote (after the public announcement of a proposal by
            a third party to acquire Enron), an Enron Superior Proposal Event or
            an Enron Board Action; and

      o     at the option of Enron during the 15-day period beginning on the
            date the Merger Agreement is terminated pursuant to a Dynegy
            Shareholder No Vote (after the public announcement of a proposal by
            a third party to acquire Dynegy), a Dynegy Superior Proposal Event
            or a Dynegy Board Action.

      The Exchange Agreement will terminate if (i) the Mergers are consummated,
(ii) the option under the Option Agreement is exercised or (iii) the Series A
Preferred is redeemed in accordance with its terms.

      In the event that Dynegy is prevented from receiving Enron Common Stock
because the conditions for the issuance have not been satisfied, Dynegy will
have the right to assign its rights under the Exchange Agreement to any third
party or Enron will issue to Dynegy shares of a new class of Enron preferred
stock convertible into an equivalent number of shares of Enron Common Stock. In
the event that the conditions for Dynegy to receive Enron Common Stock are not
satisfied after twelve months, Dynegy may instead elect to withdraw its exercise
of the exchange right and exercise its rights under the Option Agreement, or
receive equivalent consideration from Enron.


                                       8


      REGISTRATION RIGHTS AGREEMENT. Dynegy and Enron also have entered into a
Registration Rights Agreement (the "Registration Rights Agreement") that
provides for customary registration rights for the sale by Dynegy of any shares
of Enron Common Stock received upon exchange of Series A Preferred.

CHEVRON INVESTMENTS

      In connection with the Mergers, ChevronTexaco Corporation
("ChevronTexaco"), the parent corporation of Chevron U.S.A. Inc. ("Chevron"), a
shareholder of Dynegy, has agreed to invest up to an aggregate of $4.0 billion
in Dynegy and Newco. ChevronTexaco purchased $1.5 billion of Series B
Mandatorily Convertible Redeemable preferred stock, no par value ("Series B
preferred stock"), of Dynegy on November 13, 2001, the proceeds of which were
used to finance Dynegy's investment in Northern Natural. At the closing of the
Mergers, ChevronTexaco will purchase an additional $1.0 billion of Newco Class B
Common Stock, unless ChevronTexaco determines that a material adverse effect
relating to Enron has occurred in certain circumstances and opts not to fund
such purchase (the "Chevron Out"). Also at the closing, if Chevron does not
exercise the Chevron Out, Chevron will receive warrants to purchase up to an
additional $1.0 billion of Newco Class B common stock, which can be increased to
$1.5 billion if Chevron commits, at the closing of the Mergers, to purchase at
least $500.0 million of Newco Class B common stock pursuant to such warrants.

      More specifically, the following is a description of the agreements
related to ChevronTexaco and Chevron in this transaction.

      AGREEMENTS WITH DYNEGY

      SERIES B PREFERRED STOCK SUBSCRIPTION AGREEMENT. ChevronTexaco has
purchased 100,000 shares of Series B preferred stock for $1.5 billion. The terms
of the Series B preferred stock are governed by the Statement of Resolution
filed with the Secretary of State of the State of Illinois on November 13, 2001.

      Among other things, the Statement of Resolution provides for the
conversion of the Series B preferred stock into shares of Dynegy Class B common
stock, no par value ("Dynegy Class B common stock"), upon certain circumstances.
The Series B preferred stock will automatically convert into Dynegy Class B
common stock immediately preceding the closing of the Mergers, unless Chevron
exercises the Chevron Out. If Chevron exercises the Chevron Out and the Mergers
close, Chevron can elect to convert the Series B preferred stock into Dynegy
Class B common stock immediately preceding the closing of the Mergers. In either
event, the Series B preferred stock will convert into a number of shares of
Dynegy Class B common stock determined by dividing $10,000 by the conversion
price. Initially, the conversion price will be equal to the lesser of (1)
$31.635 (a 5% discount to a specified sales price of Dynegy Class A common
stock, no par value ("Dynegy Class A common stock"), on November 7, 2001) and
(2) the average of the closing prices of Dynegy Class A common stock for the
five business days immediately preceding the business day prior to the closing
of the Mergers. If, however, the Merger Agreement is terminated, Chevron can
convert the Series B preferred stock, at a conversion price of $31.635, at any
time after the Merger Agreement is terminated until (1) two years from the
funding of its purchase of the


                                       9


Series B preferred stock if Chevron exercises the Chevron Out or (2) November 9,
2003 if Chevron does not exercise the Chevron Out.

      Under certain circumstances, Dynegy is required to redeem any outstanding
shares of Series B preferred stock. If the Mergers occur, Chevron exercises the
Chevron Out and Chevron does not convert its shares, Dynegy may at any time
after, but must before the first anniversary of, the closing of the Mergers
redeem all outstanding Series B preferred stock at a redemption price of
$10,000, plus any accrued and unpaid dividends. If the Merger Agreement is
terminated, regardless of whether Chevron exercises the Chevron Out, Dynegy must
redeem all outstanding shares of Series B preferred stock at the redemption
price on the second anniversary of the issuance of the Series B preferred stock.
In this instance, Dynegy may not redeem the shares prior to the second
anniversary of the issuance of the Series B preferred stock.

      The Series B preferred stock will not accrue any dividend unless the
Mergers close and Chevron exercises the Chevron Out. Then, Chevron will be
entitled to receive a special one-time dividend at 7% per annum for the period
starting on the date on which Dynegy issued the Series B preferred stock and
ending on the date on which Chevron exercised the Chevron Out. Dynegy will pay
this special dividend on the applicable redemption date. In addition, Chevron
will be entitled to receive a regular quarterly dividend equal to 7% per annum
for the period starting on the closing of the Mergers and ending on the
redemption date.

      FIRST AMENDMENT TO REGISTRATION RIGHTS AGREEMENT. In connection with
ChevronTexaco's purchase of the Series B preferred stock, Dynegy and Chevron
have amended the existing registration rights agreement to include the shares of
Dynegy Class B common stock into which the Series B preferred stock can convert.

      PURCHASE RIGHTS AGREEMENT BETWEEN DYNEGY AND CHEVRONTEXACO. ChevronTexaco
is entitled to purchase shares of capital stock or other equity securities of
Newco to be issued upon consummation of the Mergers (after giving effect to the
cumulative changes to the Enron Merger Ratio) in exchange for any additional
shares of capital stock or other equity securities of Enron that Enron issued
between the date of the Merger Agreement and the date of the closing of the
Mergers pursuant to Section 7.1(f) of the Merger Agreement. ChevronTexaco is
entitled to purchase that number of shares to maintain its proportionate
ownership in Dynegy immediately prior to any issuance by Enron. ChevronTexaco
will purchase any such shares at a price equal to the product of (1) the number
of such additional shares purchased and (2) the closing price of Dynegy Class A
common stock on the date on which Enron issued the additional securities.

EXHIBITS AND INCORPORATION BY REFERENCE.

      The Series B Preferred Stock Subscription Agreement, the First Amendment
to the Registration Rights Agreement and the Purchase Rights Agreement are filed
herewith as Exhibits 10.1, 11 and 12, respectively, and are incorporated in this
Schedule 13D by reference. The foregoing description of the Series B Preferred
Stock Subscription Agreement, the First Amendment to the Registration Rights
Agreement and the Purchase Rights Agreement, and the transactions contemplated
in such documents, is qualified in its entirety by reference to such documents.

      AGREEMENTS WITH NEWCO

      CLASS B COMMON STOCK SUBSCRIPTION AGREEMENT. ChevronTexaco has agreed to
purchase from Newco, immediately following the consummation of the Mergers, $1.0
billion of Newco Class B common stock. ChevronTexaco will purchase the shares at
a price equal to the quotient of $1.0 billion divided by the lesser of (i)
$32.83 (a 5% discount to the five-day average closing price of Dynegy Class A
common stock as of November 7, 2001) or (ii) the average of the


                                       10


closing prices of Dynegy Class A common stock over the five consecutive trading
days ending immediately prior to one business day prior to the consummation of
the Mergers. A condition to funding is that Chevron has not exercised the
Chevron Out. If ChevronTexaco does not exercise the Chevron Out, it will also
receive warrants to purchase $1.0 billion of Newco Class B common stock, and if
it commits at the closing of the Mergers, an additional warrant obligating
ChevronTexaco to purchase an additional $500.0 million of Newco Class B common
stock.

      SERIES A WARRANT TO PURCHASE NEWCO CLASS B COMMON STOCK. This warrant
entitles ChevronTexaco to purchase from Newco, at any time until two years
following the closing of the Mergers, up to $500.0 million of Newco Class B
common stock, at a purchase price of $34.55. This warrant will only be issued at
the closing of the Mergers if Chevron does not exercise the Chevron Out.

      SERIES B WARRANT TO PURCHASE NEWCO CLASS B COMMON STOCK. This warrant
entitles ChevronTexaco to purchase from Newco up to $500.0 million of Newco
Class B common stock at the lower of (1) the average of the closing prices of
Dynegy Class A common stock for the five days immediately preceding the date on
which ChevronTexaco commits to purchase shares and (2) the average closing price
of Dynegy Class A common stock for the five days immediately preceding the date
on which ChevronTexaco notifies Newco that it will settle such commitment.
ChevronTexaco may commit to exercise this warrant at any time until one year
following the closing of the Mergers, unless ChevronTexaco commits, at the
closing of the Mergers, to purchase all of the shares subject to the Series C
warrant, in which case ChevronTexaco will have two years following the closing
of the Mergers to commit to exercise this warrant. ChevronTexaco must give Newco
notice that it will settle each commitment within one year from date on which
ChevronTexaco committed to purchase shares pursuant to this warrant. This
warrant will only be issued at the closing of the Mergers if Chevron does not
exercise the Chevron Out.

      SERIES C WARRANT TO PURCHASE NEWCO CLASS B COMMON STOCK. If Chevron elects
to receive this warrant, this warrant will obligate ChevronTexaco to purchase
from Newco $500.0 million of Newco Class B common stock at the lower of (1) the
average of the closing prices of Dynegy Class A common stock for the five days
immediately preceding the date on which ChevronTexaco commits to purchase shares
and (2) the average closing price of Dynegy Class A common stock for the five
days immediately preceding the date on which ChevronTexaco notifies Newco that
it will settle such commitment. ChevronTexaco must commit to exercise all of
this warrant on or before the date that is one year following the closing of the
Mergers, or it will be deemed to have committed to purchase any remaining
shares. ChevronTexaco must give Newco notice that it will settle each commitment
within one year from date on which ChevronTexaco committed to purchase shares
pursuant to this warrant. If ChevronTexaco elects to receive this warrant, the
exercise term of the Series B warrant will be extended to two years, instead of
one, from the closing of the Mergers. This warrant will only be issued at the
closing of the Mergers if Chevron does not exercise the Chevron Out and if
Chevron commits to purchase the shares underlying this warrant as of the closing
of the Mergers.

      STOCKHOLDER AGREEMENT. Newco, Dynegy, Enron and Chevron have entered into
a stockholder agreement that will govern certain aspects of their relationship
before and after the Mergers. This agreement is similar to the Shareholder
Agreement, dated as of June 14, 1999, among Dynegy, Illinova Corporation, Dynegy
Holdings Inc. and Chevron. The key differences between the Dynegy shareholder
agreement and the Newco stockholder agreement are that under the Newco
stockholder agreement (1) Chevron is entitled to elect the greater of three
directors and 20% of Newco's board of directors, if Newco's board is increased
in size, and (2) Newco is not prohibited from owning an interest in a nuclear
facility.


                                       11


      This agreement will terminate upon the termination of the Merger Agreement
and Chevron's ceasing to own certain specified thresholds of Newco common stock.

      NEWCO REGISTRATION RIGHTS AGREEMENT. Newco has granted Chevron
registration rights, which are similar to those contained in the registration
rights agreement, dated as of June 14, 1999, between Dynegy and Chevron, for the
Newco Class A common stock underlying the Newco Class B common stock that
Chevron will own following the Mergers. This agreement will terminate upon the
first such instance when Chevron (including its affiliates) ceases to own at
least one percent (1%) of Newco's outstanding common stock (treating the Newco
Class B common stock as if it had been converted into Newco Class A common stock
in accordance with its terms).

EXHIBITS AND INCORPORATION BY REFERENCE.

      The Class B Common Stock Subscription Agreement (including the forms of
the Series A Warrant, the Series B Warrant and the Series C Warrant attached as
Exhibits A, B and C thereto), the Stockholder Agreement and the Newco
Registration Rights Agreement are filed herewith as Exhibits 13, 14 and 15,
respectively, and are incorporated in this Schedule 13D by reference. The
foregoing description of the Class B Common Stock Subscription Agreement, the
Stockholder Amendment and the Newco Registration Rights Agreement and the forms
of the Series A Warrant, the Series B Warrant and the Series C Warrant, and the
transactions contemplated in such documents, is qualified in its entirety by
reference to such documents.

      GENERAL.

      Except as contemplated by the Merger Agreement and the other agreements
and documents set forth as exhibits to this Schedule 13D, Dynegy has no current
intention of acquiring or disposing of shares of Enron Common Stock or taking
any other action referred to in Item 4 of Schedule 13D; however, Dynegy's
intentions may change in light of the facts and circumstances that may arise in
future dealings in the marketplace, actions of other parties, or other events
affecting Enron or Dynegy and the operation of the terms of those agreements and
documents. Although none of the reporting persons has a present intention to
acquire additional shares of Enron Common Stock or to dispose of shares of Enron
Common Stock beneficially owned by such reporting person, any of the reporting
persons, acting alone or separately, may in the future acquire beneficial
ownership of additional shares of Enron Common Stock or dispose of shares of
Enron Common Stock beneficially owned by such reporting person.

      (d) If the Mergers are consummated, the directors of Sorin, Inc. will
become the directors of the Issuer. In addition, Newco is expected to change
certain of the executive officers of the Issuer.

      (e) Other than as a result of the Mergers described in response to Item 4,
not applicable.

      (f) Not applicable.

      (g) Other than as described in response to Item 4, not applicable. If the
Merger is consummated, Sorin, Inc. will merge into the Issuer and the Issuer
will become a wholly owned subsidiary of Newco. Under the terms of the Merger
Agreement, the parties thereto may, by amendment, provide for an alternative
structure that would result in a single corporation with substantially all the
senior debt (other than that of regulated utility subsidiaries) of Dynegy,
Dynegy Holdings Inc. (a subsidiary of Dynegy) and Enron, in lieu of the mergers
provided for in the Merger Agreement as originally executed. The Merger
Agreement provides for limitations on the solicitation by Enron, its directors,
officers, employees, agents, affiliates or other representatives of any proposal
or offer (other than by Dynegy) with respect to certain types of


                                       12


business combinations and transactions. The Stockholder Agreements have similar
limitations on the parties to those agreements and their officers, directors,
employees, partners, agents, affiliates or other representatives. The Merger
Agreement also provides for a $297.5 million termination fee payable to Dynegy
by Enron, and a $52.5 million termination fee payable to ChevronTexaco by Enron,
if the Merger Agreement is terminated under certain circumstances.

      (h) - (i) If the Merger is consummated, the Enron Common Stock will be
deregistered under the Act and delisted from the New York Stock Exchange.

      (j) See above.

ITEM 5.     INTEREST IN SECURITIES OF ENRON.

      The information set forth or incorporated by reference in Items 2, 3 and 4
is hereby incorporated herein by reference.

      (a)-(b) Dynegy beneficially owns no shares of Enron Common Stock other
            than as set forth herein. The executive officers and directors of
            Dynegy are listed on Annex A hereto. Dynegy has made inquiry of its
            executive officers and directors regarding their beneficial
            ownership of Enron securities and all responses to such inquiries
            received as of the date hereof have been reported herein. Dynegy
            believes that the non-responding officers and directors either own
            no securities of Enron or own an amount that, if included herein,
            would not affect the percentage reported on the cover page of this
            Schedule 13D. If further information that would change the
            percentage reported on the cover page of this Schedule 13D comes to
            Dynegy's attention, Dynegy will file an amendment to this Schedule
            13D that reflects such further information. Pursuant to the Exchange
            Agreement and as described above, Dynegy may exchange shares of
            Series A Preferred for 169,300,225 shares of Enron Common Stock,
            subject to adjustment, under the circumstances set forth in response
            to Item 4 hereof.

            Neither the filing of this Schedule 13D nor any of its contents
            shall be deemed to constitute an admission that Dynegy is the
            beneficial owner of the shares of Enron Common Stock subject to the
            Exchange Agreement for purposes of Section 13(d) or Section 16 of
            the Act or for any other purpose.

      (c)   Except as described in Item 4 hereof, no transactions in the Enron
            Common Stock were effected by Dynegy, or, to the knowledge of
            Dynegy, any of the persons listed on ANNEX A hereto, during the past
            60 days.

      (d)   Until the exchange under the Exchange Agreement, if such exchange
            ever takes place, Dynegy has no right to receive or the power to
            direct the receipt of dividends from, or the proceeds from the sale
            of, the Enron Common Stock subject to exchange. If the exchange
            takes place, Dynegy, or its designee, if any, would have the right
            to receive, and the power to direct the receipt of, dividends on the
            shares of Enron Common Stock acquired pursuant thereto.

      (e)   Not applicable.

ITEM 6.     CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
            RESPECT TO SECURITIES OF ENRON.

      Except as set forth in this Schedule 13D, to the knowledge of Dynegy,
there are no other contracts, arrangements, understandings or relationships
(legal or otherwise) among the persons named in Item 2 or listed on ANNEX A
hereto, and between such persons and any person, with respect to any


                                       13



securities of Enron, including, but not limited to, transfer or voting of any of
the securities of Enron, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees or profits, division of profits or loss,
or the giving or withholding of proxies.
