From:      Marie Dreher, Myra Perkinson, Gus Williamson   Date:  June 8, 2004

Subject:   TIO2 ORGANIZATIONAL ANNOUNCEMENT PENDING       Location:  Hunt Valley
           THE CLOSE OF OUR PROPOSED BUSINESS
           COMBINATION

To:        All Millennium Employees

Today we are pleased to announce the planned reporting structure for the TiO2
business, with four functions that will report directly to Bart de Jong, the
General Manager, TiO2, at the close of the proposed transaction with Lyondell.
These functions include Global Manufacturing, Research & Development, Sales &
Marketing, and Supply Chain.

All of these functions will continue to be operated out of Baltimore, Md., with
business and support resources necessary for the ongoing needs of the business.

Upon the close of the proposed business combination with Lyondell it is
anticipated that:

BRIAN GOEDKE will become Vice President of the global MANUFACTURING
organization, with responsibility for Millennium's titanium dioxide facilities
in the United States, France, United Kingdom, Australia and Brazil. All site
directors will report directly to Brian. In addition, a global manufacturing
support function will be established, also reporting to Brian, which will
support the achievement of global consistency in manufacturing practices and
play a key role in assuring that manufacturing best practices are shared between
Lyondell, Equistar and Millennium. The Quality group which currently reports to
the Corporate Safety, Health and Environment (SHE) organization will report into
this new manufacturing support function. The TiO2 Central Engineering and
Technology function will report directly to the Lyondell Engineering
organization with a dotted line to Brian. The Health, Safety and Environmental
function also will report into Lyondell with dotted line to Brian.



GARY CIANFICHI will continue as Vice President of the global MARKETING AND SALES
organization for TiO2 and Performance Chemicals. No material organizational
changes are anticipated.

BOB DANIELS will continue as Vice President of global TiO2 RESEARCH AND
DEVELOPMENT (R&D), which will continue to be coordinated out of the RCB research
facility. Upon the close of the proposed transaction, the ACETYLS R&D activities
will be reporting into the Lyondell (Intermediate Chemicals & Derivatives) R&D
organization.

CLEVER FONSECA will continue as Vice President, global TiO2 SUPPLY CHAIN. In
this capacity he will have responsibility for both "sell" side and "buy" side
supply chain functions. As part of supporting the Manufacturing organization in
achieving lower controllable costs, Clever will continue to be responsible for
the mining operations in Brazil. In addition, the Ferrica Products business will
also report to Clever, and he will provide executive-level direction to the Six
Sigma activities.

The Integration Team is working diligently to complete the proposed design for
the various TiO2 support functions as well as the Acetyls organization, and we
expect to be able to announce the planned leadership roles for these
organizations shortly.
