Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Prior to the Merger (as defined below), Cantor Fitzgerald, L.P. ("CFLP") separated (the "Separation") its inter-dealer brokerage, market data and fulfillment businesses (collectively, the "BGC Businesses") from the remainder of CFLP's businesses and contributed the BGC Businesses to BGC Partners, LLC, which then merged (the "Merger") with and into eSpeed, Inc., which was renamed BGC Partners, Inc. (the "Company"). The Merger was completed on April 1, 2008. In connection with the Separation and Merger, the reporting person received from CFLP in respect of his CFLP limited partnership units 2,515,898 BGC Holdings, L.P. ("BGC Holdings") Founding Partner Interests (the "Founding Partner Interests"), and received from the Company 2,515,898 exchange rights, entitling the reporting person to exchange his Founding Partner Interests for shares of Class A Common Stock on a one-for-one basis (subject to adjustment) (the "Exchange Rights"). (Continued footnote 2)
(2) The Exchange Rights vest on the following schedule: (i) 600,000 of the Exchange Rights vested on the completion of the Merger (500,000 of which were exercised on February 22, 2010), (Continued footnote 3)
(3) (ii) 40% of the Exchange Rights (less the 600,000 referred to in clause (i) and any other interests or shares of Class A Common Stock that the reporting person is otherwise eligible to exchange or sell or has sold for any reason, including, without limitation, in connection with any grant of additional interests or stock options (collectively, the "Applicable Shares")) will vest on the second anniversary of the completion of the Merger, (iii) 50% of the Exchange Rights (less the Applicable Shares) will vest on the third anniversary of the completion of the Merger, (iv) 60% of the Exchange Rights (less the Applicable Shares) will vest on the fourth anniversary of the completion of the Merger, (v) 70% of the Exchange Rights (less the Applicable Shares) will vest on the fifth anniversary of the completion of the Merger, (Continued footnote 4)
(4) (vi) 80% of the Exchange Rights (less the Applicable Shares) will vest on the sixth anniversary of the completion of the Merger, (vii) 90% of the Exchange Rights (less the Applicable Shares) will vest on the seventh anniversary of the completion of the Merger, and (viii) 100% of the Exchange Rights (less the Applicable Shares) will vest on the eighth anniversary of the completion of the Merger. (Continued footnote 5)
(5) Once the Exchange Rights become exercisable, they are exercisable at any time and are automatically exercised upon redemption of the related Founding Partner Interests for any reason. In the case of the death of the reporting person, the Exchange Rights with respect to the related Founding Partner Interests that are then not vested are automatically exercised and the shares are distributed on the same schedule as if the reporting person had not died and had exchanged the maximum amount possible on each anniversary of the completion of the Merger.
