Confirmation of Approach to eSpeed Inc

18 April 2007

                              Tullett Prebon plc                               

                    Confirmation of Approach to eSpeed Inc                     

Tullett Prebon plc confirms that it has made an approach to eSpeed, Inc in
relation to a possible acquisition by Tullett Prebon of eSpeed at a price of
$12 per eSpeed Class A Common Share in cash.

This proposal is subject to a number of conditions including, inter alia, the
conversion of all eSpeed outstanding Class B Common Shares to Class A Common
Shares and the termination at immaterial cost or adjustment to arms length
terms of eSpeed's arrangements with its affiliates including those with Cantor
Fitzgerald L.P. ("Cantor"). The Class B Common Shares are a supermajority
voting class which is owned by Cantor and which is the basis for Cantor's
voting control of eSpeed.

eSpeed referred this proposal to Cantor and has informed Tullett Prebon that
Cantor is not interested in selling its controlling interest on the terms
proposed.

Terry Smith, Chief Executive of Tullett Prebon, commented:

"Our first approach to eSpeed two years ago was rejected but we continue to
regard the strategic fit with Tullett Prebon as compelling.

"Since then eSpeed's stock has remained flat whilst Collins Stewart Tullett's
stock, from which Tullett Prebon was demerged in December 2006, has risen by
47%, taking into account the substantial return of capital (some £300 million/
$600 million) to the shareholders of Tullett Prebon. Had eSpeed agreed to be
acquired two years ago, its stockholders would have been able to share in that
performance.

"We believe that our proposal is in the best interests of eSpeed's
shareholders other than Cantor and those associated with it, and would unlock
shareholder value that is now unavailable to the minority shareholders.

"Moreover, we believe that some of the major dealer clients of eSpeed would
prefer its platform to be owned and operated by Tullett Prebon so that the
proposed change of ownership could be expected to enhance the utility and
eventual value of the platform.

"We would highlight the fact that eSpeed's board has not deemed it necessary
to consult with any interested party other than Cantor in reaching this
decision."
