Dr. Kenneth L. Lay
Chairman & CEO
Enron Corp.

Dear Dr. Lay:

In the wake of recent events, I want to confirm that CERA is proceeding
with CERAWeek 2002, to be held in Houston, Texas on February 11-15,
2002.   This year's theme  "The New Face of Risk: Energy Strategies for
the Changed World" will offer timely insight on the new economic and
geopolitical realities - and their implications for the energy future.
The events of the past weeks have had a profound impact on all segments
of the energy industry. We look forward to our February gathering as an
opportunity for leaders of the energy community to exchange ideas.  For
complete details of the event, please visit our website at:

registering early this year.  To acknowledge your early commitment and
support for CERAWeek, we are offering significant incentives for early

Offering an integrated agenda across the week, underscoring the key
