Attached as Appendix A is information concerning each partner of
Chicago and the executive officers and directors of Lemont, Midwest 76, Midwest,
Union and Unocal required to be disclosed in response to Item 2 and General
Instruction C to Schedule 13D. Such persons may be deemed, but are not conceded
to be, controlling persons of these entities. Collectively, Chicago, Lemont,
Midwest 76, Midwest, Union and Unocal are hereinafter referred to as the
"Reporting Persons."
(d) During the past five years, none of the Reporting Persons nor any
of the persons referred to in Appendix A has been convicted in a criminal
proceeding (excluding traffic violations and similar misdemeanors).
(e) None of the Reporting Persons nor any of the persons referred to in
Appendix A has been 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, during the last five years.
(f) All persons named in Appendix A are citizens of the United States.
Item 3. Source and Amount of Funds or Other Consideration.
Not applicable. See Item 4.
Item 4. Purpose of Transaction.
Union Oil originally purchased the shares of Common Stock reported herein
for the purpose of investment. Union Oil subsequently sold the shares to Chicago
in order to achieve a more tax-efficient corporate holding structure for the
shares and at the time Chicago acquired the shares for the purpose of
investment. Under the Stock Ownership and Registration Rights Agreement, dated
as of June 29, 1999 by and between Union Oil and the Issuer (the "Stock
Ownership Agreement"), a copy of which is attached hereto as Exhibit B, Union
Oil retained (and pursuant to the Addendum referred to in the next sentence,
Chicago succeeded to) the absolute right to vote its shares of Common Stock as
it individually determined except as otherwise described in Item 6 hereof and in
the Stock Ownership Agreement. Upon the sale of the shares to Chicago, Chicago,
Union Oil and the Issuer executed an addendum to the Stock Ownership Agreement
(the "Addendum"), attached hereto as Exhibit C, whereby Chicago became a party
to the agreement and became bound by the same obligations as Union Oil under the
agreement. With respect to plans or proposals that Union Oil may have that
relate to any change in the present board of directors or management of the
Issuer, Union Oil has the right under the Addendum to designate one member of
the board of directors of the Issuer. Union Oil's current designated director to
the Issuer's board of directors is Mr. Kenneth Butler.
The Stock Ownership Agreement affords Chicago certain rights,
including the right to: (i) require the Issuer to undertake, from time to time,
the registration with the U.S. Securities and Exchange Commission (the "S.E.C.")
some or all of the shares of Common Stock it owns, subject to customary
limitations as set forth in the Stock Ownership Agreement; (ii) request that
some or all of its shares of Common Stock be included with other shares of
Common Stock that the Issuer proposes to register with the S.E.C., whether such
registration relates to a primary or secondary offering or an offering of shares
of Common Stock under a universal shelf registration statement subject to
customary limitations as set forth in the Stock Ownership Agreement; and (iii)
to acquire as many shares of Common Stock as may be required to maintain its
then current ownership percentage if the Issuer sells or transfers additional
shares of Common Stock that would otherwise dilute Chicago's ownership
percentage.
On May 1, 2003, the Issuer filed a universal shelf registration
statement on S.E.C. Form S-3 to sell up to $500,000,000 of debt or equity
securities. In response to the Issuer's filing as well as other strategic
business considerations, Chicago is presently considering its options with
respect to the shares of Common Stock it holds, including whether to sell some
or all of them by exercising its registration rights under the Stock Ownership
Agreement or otherwise. It is unlikely that Chicago will exercise its right to
acquire additional shares of Common Stock in accordance with its rights under
the Stock Ownership Agreement.
Item 5. Interest in the Securities of the Issuer.
(a) There were 39,420,303 shares of Common Stock outstanding as of March
31, 2003. The Reporting Persons are deemed to be the beneficial owners of
5,800,000 shares of Common Stock, which constitute approximately 14.71323% of
the total issued and outstanding Common Stock as of March 31, 2003.
(b) Chicago is controlled by three general partners - Lemont, Midwest 76
and Midwest - which are wholly owned subsidiaries of Union. Union is a wholly
owned subsidiary of Unocal. Therefore, Unocal may be deemed to control Union,
9
Lemont, Midwest 76, Midwest, and Chicago. Thus, the Reporting Persons may be
deemed to share voting power and investment power with respect to the Common
Stock.
(c) None of the Reporting Persons, nor any person listed on Appendix A,
has effected any transactions in the Common Stock during the past 60 days.
(d) To the best of the knowledge of the Reporting Persons, none of the
Reporting Persons nor any person listed on Appendix A beneficially owns any
Common Stock of the Issuer except as set forth above. To the best of the
knowledge of each reporting Person, no persons other than Chicago has the right
to receive or the power to direct the receipt of dividends from, or the proceeds
from the sale of, the shares of Common Stock beneficially owned by the Reporting
Persons.
(e) Not applicable.
Item 6. Contracts, Arrangements, Understandings or Relationships with
Respect to Securities of the Issuer.
The shares of Common Stock acquired by Union and subsequently sold to
Chicago were acquired in a private placement and are restricted securities.
Pursuant to the Stock Ownership Agreement, Union retained the absolute right to
vote its shares of Common Stock as it individually determined except that for so
long as Union owns greater than 10% of Common Stock, it must vote its shares in
favor of the director nominees recommended by the management of the Issuer. In
addition, certain transfer restrictions, and registration rights granted by the
issuer are set forth in the Stock Ownership Agreement, a copy of which was
included as Exhibit B to Schedule 13D filed on July 12, 1999. After the sale of
the shares to Chicago, Union and the Issuer executed an addendum to the Stock
Ownership Agreement (included as Exhibit B to this Schedule 13D) which has the
same force and effect as if Chicago had executed a counterpart of the Stock
Ownership Agreement. Additionally, the Issuer and Union executed a covenant
(attached as Exhibit D to this Schedule 13D) whereby the Issuer consents to the
transfer, Chicago agrees to comply with the terms and conditions of the Stock
Ownership Agreement, and Union agrees to certain conditions including
maintaining not less than 80% o the voting power of Chicago. Union and Chicago
also executed a Clarification and Assignment (filed as Exhibit E to this
Schedule 13) whereby Union assigns, conveys, and delivers to Chicago al of
Union's rights, title and interest in to, and under the Stock Ownership
Agreement (other than Union's rights, titles, and interests under Article 111 of
the Stock Ownership Agreement, relating to Union's right to designate a director
or a director nominee to the Board of Directors of the Issuer.
Item 7. Material to be Filed as Exhibits.
Exhibit A Joint Filing Agreement, dated June 3, 2003.
Exhibit B Stock Ownership and Registration Rights Agreement, dated as
of June 29, 1999 by and between Union Oil and the Issuer
(incorporated by reference to Exhibit B to the Schedule 13D of
the Reporting Persons filed July 12, 1999).
Exhibit C Addendum to Stock Ownership and Registration Rights Agreement
dated as of September 30, 1999 by and between Union and Chicago
(incorporated by reference to Exhibit B to the Schedule 13D/A
of the Reporting Persons filed November 16, 1999).
Exhibit D Unocal Covenant dated as of September 30, 1999 (incorporated
by reference to Exhibit C to the Schedule 13D/A of the
Reporting Persons filed November 16, 1999).
Exhibit E Clarification and Assignment dated as of September 30, 1999
by and between Union and Chicago (incorporated by reference to
Exhibit D to the Schedule 13D/A of the Reporting Persons filed
November 16, 1999).
