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


London,  England  and Red Bank,  New  Jersey,  June 28,  2001 -  Millennium
Chemicals (NYSE - MCH) ("Millennium")  announced today that as party of its
previously  announced  initiative to accelerate cost savings,  it will idle
its  sulfate-process  titanium  dioxide  (TiO2)  facility at Hawkins Point,
Maryland and reduce its worldwide workforce by approximately 10%.

IDLING ONE TIO2 PLANT, RERATING TWO OTHERS
- ------------------------------------------

Millennium   will  idle  its   high-cost   44,000  metric  tons  per  year,
sulfate-process  TiO2 plant in Hawkins  Point,  Maryland for an  indefinite
period on  September  1, 2001.  The idled plant  primarily  serves the U.S.
paper industry. Customers will not be impacted by this action, as they will
be provided product from Millennium's  other TiO2 plants.  This action will
lower global manufacturing costs per metric ton. Millennium's 50,000 metric
tons per year  chloride-process  plant at Hawkins  Point will  continue  to
operate.  As a  result  of  recent  minor  bottlenecking  and  demonstrated
operating results, the chloride-process TiO2 plants in Kemerton,  Australia
and Ashtabula,  Ohio have been re-rated,  increasing capacity by 10,000 and
12,000  metric  tons  per  year,  respectively.  Millennium's  annual  TiO2
capacity is now 690,000  metric tons per year, or 3% less than before these
actions, of which 73 percent utilize chloride-process technology.

GLOBAL WORKFORCE REDUCTION
- --------------------------

In order to streamline  the cost  structure at existing  operations  and to
optimize cash flow from its more mature businesses,  Millennium is reducing
its 4,300 global workforce by about 10 percent,  including 250 employees at
the Hawkins Point facility.

FINANCIAL IMPACT
- ----------------

As a result of these actions, Millennium will incur one-time charges in the
second quarter of 2001 of approximately $30 million,  including $10 million
of non-cash asset impairment  charges.  Cost savings  associated with these
steps are  expected to exceed $25  million  annually.  Millennium  plans to
release second quarter results on Thursday, July 26, 2001.
