      HOWARD LUTNICK, CHAIRMAN OF CANTOR FITZGERALD AND ESPEED, COMMENTS ON

                           WORLD TRADE CENTER TRAGEDY

     NEW YORK - September 12, 2001 6:55 PM Eastern - Cantor Fitzgerald, L.P.,
eSpeed Inc. (NASDAQ: ESPD) and Tradespark L.P., today issued the following
statement by Howard Lutnick, Chairman of Cantor Fitzgerald, regarding the World
Trade Center tragedy.

     "All of us are shocked by the terrible events at the World Trade Center,
and we are gathering with our families, friends and colleagues to cope with this
devastating situation. As many of you know, Cantor Fitzgerald, eSpeed and
TradeSpark had offices and significant operations on the top floors of One World
Trade Center that employed approximately 1,000 people.

     "Naturally our first priority is the whereabouts and the welfare of our
employees and their families. It is clear that we have incurred a heavy loss of
life among our colleagues and friends, though we do not at this time have any
means of determining with certainty the whereabouts of employees who are missing
or unaccounted for. We have identified many New York area employees who are
safe. We are working with all authorities and will not give up hope that
additional employees will be discovered or rescued. We cannot give further
detail on the number of lost employees until we have confirmed information.



     "At the same time, we wish to reaffirm that our firms will continue the
work, success and foundation built by our lost colleagues. We will not allow
this tragedy to sway us from our path - while we grieve, we intend to persevere.
We remain confident that our systems and technology will perform as our
customers have come to expect. Our concurrent computing centers in New Jersey
and London are unimpaired. Although the impact on most of our products is in the
process of being evaluated, we expect that trading in Treasury and Agency
securities and equities with U.S. settlement will resume when the markets
reopen, or shortly thereafter, while trading in other domestic U.S. products
will be brought back on line as our concurrent computing unit in New Jersey
restores systems.

     "We are thankful for the outpouring of support we have received from so
many people. With their help, we are doing everything possible to move ahead. We
are grateful for each and every employee we have and all of eSpeed, Cantor
Fitzgerald and Tradespark join together in prayer and hope for our lost family,
friends and colleagues." For updated information please visit www.espeed.co.uk
