Person") and NOVA hereby amend the single joint statement on Schedule 13D, as
amended by Amendments 1, 2 and 3 (the "Schedule 13D"), filed with the Securities
and Exchange Commission, which statement relates to the shares of Common Stock,
par value $0.01 (the "Shares") of Dynegy Inc. (known prior to July 6, 1998 as
NGC Corporation), a Delaware corporation (the "Corporation") as follows:

ITEM 2.    IDENTITY AND BACKGROUND.

Item 2 shall be deleted and replaced with the following:

        (a, b, c and f) This Statement is being filed by (i) NOVA Gas Services
(U.S.) Inc., a Delaware corporation (the "Reporting Person"), and (ii) NOVA
Corporation, an Alberta, Canada, corporation ("NOVA"). The Reporting Person is a
wholly owned subsidiary of NOVA Investments (U.S.) Inc. which is, in turn, a
wholly owned subsidiary of Novamerica Investments Ltd., which is, in turn, a
wholly owned subsidiary of NOVA Chemicals Ltd., which is in turn a wholly owned
subsidiary of NOVA. The principal office of the Reporting Person is 400
Frankfort Road, Monaca, Pennsylvania 15601. The principal office of NOVA is 645
Seventh Avenue S.W., Calgary, Alberta T2P 4G8 Canada.

        The principal business of the Reporting Person is to hold NOVA's U.S.
gas services investments. The principal business of NOVA is the manufacturing
and marketing of commodity chemicals.

        Schedules I and II which are attached hereto and incorporated herein in
their entirety by reference, set forth the name, residence or business address,
citizenship and certain employment information of each of the officers and
directors of the Reporting Person and NOVA, respectively. 

        (d) Neither the Reporting Person, nor NOVA, nor to the best knowledge of
either the Reporting Person or NOVA, any entity or person with respect to which
information is provided in response to this Item 2 has, during the last five
years, been convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).

        (e) Neither the Reporting Person, nor NOVA, nor to the best knowledge of
either the Reporting Person or NOVA, any entity or person with respect to which

years, been a party to a civil proceeding of a judicial or administrative body

ITEM 4.    PURPOSE OF TRANSACTION.

The following shall be added before the last paragraph of Item 4:

        On August 24, 1998, NOVA issued a press release stating that it had
engaged the investment banking firm Merrill Lynch & Co. to identify and evaluate
opportunities relating to the divestiture of its ownership in Dynegy. This
decision is part of NOVA's continued implementation of its strategic plan to
concentrate on its commodity chemicals business.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER.

Item 5 shall be deleted and replaced with the following:

        (a)  In computing their respective aggregate percentage ownership of
             Common Stock and the percentages of Common Stock owned by the other
             parties to the New NGC Stockholders Agreement for purposes of this
             Schedule 13D, the Reporting Person and NOVA have relied on the
             quarterly report on Form 10-Q for the quarterly period year ended
             June 30, 1998, (Commission File No.1-11156) in which the
             Corporation reported that 152,778,072 shares of Common Stock were
             outstanding. As of the close of business on August 21, 1998, the
             Reporting Person is the beneficial owner of 38,789,876 shares of
             Common Stock, constituting approximately 25.4% of the shares of
             Common Stock outstanding.

             In addition to the shares of Common Stock owned by the Reporting
             Person, the Reporting Person believes that as of August 21, 1998,
             an additional 77,579,752 shares of Common Stock (approximately
             50.8%) are subject to the New NGC Stockholders Agreement. The
             Reporting Person and NOVA disclaim ownership of any of such shares
             of Common Stock.

             NOVA does not own any shares of the Corporation directly, but may
             be deemed to share beneficial ownership of all of the shares of
             Common Stock owned by the Reporting Person by virtue of the
             ownership relationship described in Item 2.

             To the knowledge of the Reporting Person and NOVA, only the
             following persons listed on Schedule I owns any of the
             Corporation's Shares:


                    Name                      Number of Shares
                    ----                      ----------------
             Jeffrey M. Lipton                    8,450*
             A. Terence Poole                     4,295
             Jack S. Mustoe                         774
             Robert J. Pierce                       500

             *Includes 800 shares held indirectly.

             The Reporting Person and NOVA disclaim ownership of any such 
             Shares.

        (b)  Subject to its obligations under the agreements described in this
             Schedule 13D, the Reporting Person has the sole power to vote and
             dispose of the 38,789,876 shares of Common Stock owned directly by
             it. Although the Reporting Person has sole voting rights, NOVA may
             be deemed to share voting and dispositive power with regard to such
             shares by virtue of its ownership of 100% of the Reporting Person.

        (c)  The Reporting Person had no transactions in the shares of Common
             Stock in the sixty-day period ended August 24, 1998.

        (d)  Except as described above, no other person is known to have the
             right to receive or the power to direct the receipt of dividends
             from or the proceeds from the sale of such shares of Common Stock
             beneficially owned by the Reporting Person and NOVA.

        (e)  Not applicable.

             After reasonable inquiry and to the best of the undersigneds'
knowledge and believe, the undersigned hereby certify that the information set
forth in this statement is true, complete and correct.
