(a) as promptly as practicable after the date hereof cause to be filed a registration statement pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”), which Shelf Registration Statement shall provide for resales of all Registrable Securities held by Holders; and

(b) use its reasonable best efforts to cause the Shelf Registration Statement to be declared effective by the SEC as soon as reasonably practicable after filing and to remain effective until the period described in Section 3.1(a) hereof.

Section 2.2 Demand Registration. In addition to registration of Registrable Securities under Section 2.1 hereof, any Holder or group of Holders may at any time make a written request (a “Demand Request”) for registration on any appropriate form under the Securities Act of a number of Registrable Securities by means of a public offering involving an underwriting that (i) represents at least 5% of either the Notes or the shares of Class A Common Stock outstanding on the date of the Demand Request or (ii) has an aggregate market value on the date of the Demand Request of greater than $7.5 million (such written Request, a “Demand Registration”). Such Demand Requests shall specify the amount of Registrable Securities to be registered and the intended method or methods of disposition. BGC Partners shall, subject to the provisions of this Section 2.2 and to the Holders’ compliance with their obligations under the provisions of this Agreement, as promptly as practicable register under the Securities Act all Registrable Securities included in such Demand Request, for disposition in accordance with the intended method or methods set forth therein. Shares of Class A Common Stock may be registered for offer and sale in any Demand Registration: (A) by BGC Partners if and only if the Investor consents to such registration and (B) pursuant to any contractual piggyback registration of third parties; provided, however, that all Registrable Securities included in such Demand Request shall first be included in such registration, followed by any such shares on a pro rata basis. As promptly as practicable thereafter, but subject to Section 2.4 hereof, BGC Partners shall use its reasonable best efforts to file with the SEC a Registration Statement, registering all Registrable Securities that any Holders have requested to register, for disposition in accordance with the intended method or methods set forth in their notices to BGC Partners. BGC Partners shall use its reasonable best efforts to cause such Registration Statement to be declared effective by the SEC as soon as reasonably practicable after filing and to remain effective until the period described in Section 3.1(a) hereof.

Section 2.3 Number and Timing of Registrations. Notwithstanding anything in this Article II to the contrary, the Holders shall be entitled to make no more than an aggregate of four Demand Registrations hereunder (and no more than one Demand Registration during any twelve-month period).

-4-

Section 2.4 Suspension of Registration. Notwithstanding the foregoing, if in the good faith judgment of the Board of Directors of BGC Partners it would be materially detrimental to BGC Partners and its stockholders for any Registration Statement to be filed or for any Registration Statement or Prospectus to be amended or supplemented because such filing, amendment or supplement would (i) require disclosure of material non-public information, the disclosure of which would be reasonably likely to materially and adversely affect BGC Partners and its subsidiaries (if any) taken as a whole, or (ii) materially interfere with any existing or prospective business situation, transaction or negotiation involving BGC Partners, BGC Partners shall have the right to suspend the use of the applicable Registration Statement or delay delivery or filing, but not the preparation, of the applicable Registration Statement or Prospectus or any document incorporated therein by reference, in each case for a reasonable period of time; provided, however, that BGC Partners shall not be able to exercise such suspension right more than twice in each 12-month period aggregating not more than 150 days in such 12-month period.

Section 2.5 Interrupted Registration. A registration requested pursuant to Section 2.2 shall not be deemed to have been requested by the Holders of Registrable Securities for purposes of Section 2.3: (i) unless it has been declared effective by the SEC; (ii) if after it has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the SEC for any reason other than misrepresentation or an omission by the requesting Holders such that the Registration Statement shall not be effective until the earlier of (A) 60 days following the date on which it was declared effective (treating any suspension or interruption of registration as provided in Section 2.4 and (B) the date on which all of the Registrable Securities covered thereby are disposed of in accordance with the method or methods of disposition stated therein; (iii) if the conditions to closing specified in the underwriting agreement, if any, entered into in connection with such registration are not satisfied other than by reason of some wrongful act or omission, or act or omission in bad faith, by such Holders and are not otherwise waived; or (iv) if such request has been withdrawn by the requesting Holders and such Holders shall have elected to pay all Registration Expenses of BGC Partners in connection with such withdrawn request.

Article III

Registration Procedures

Section 3.1 Use Reasonable Best Efforts. In connection with BGC Partners’ registration obligations pursuant to Article II hereof, BGC Partners shall use its reasonable best efforts to effect such registrations to permit the sale of such Registrable Securities in accordance with the intended method or methods of disposition thereof and pursuant thereto BGC Partners shall as expeditiously as reasonably practicable:

(a) prepare and file with the SEC a Registration Statement or Registration Statements relating to the registration on the appropriate form under the Securities Act, and to cause such Registration Statement to be declared effective by the SEC as soon as reasonably practicable and to remain effective for the period of time necessary to permit the Holder to

BGC Partners hereby agrees to promptly reimburse any selling Holders for any reasonable out-of-pocket losses and expenses incurred in connection with any uncompleted sale of any Registrable Securities in the event that BGC Partners fails to timely notify such Holder that the Registration Statement then on file with the SEC is no longer effective;

Section 5.3 Notices of Claims. Promptly after receipt by a Holder Covered Person or a BGC Partners Covered Person (each, an “Indemnified Party”) of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Article V, such Indemnified Party will, if a claim in respect thereof is to be made against, respectively, BGC Partners, on the one hand, or any selling Holder, on the other hand (such Person or Persons, the “Indemnifying Party”), give written notice to the latter of the commencement of such action; provided, however, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its or their obligations under this Article V, except to the extent that the Indemnifying Party is actually materially prejudiced by such failure to give notice, and in no event shall such failure relieve the Indemnifying Party from any other liability which it may have to such Indemnified Party. If any such claim or action shall be brought against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party shall not be liable to such Indemnified Party under this Article V for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, other than reasonable cost of investigation; provided, further, that if, in the Indemnified Party’s reasonable judgment, a conflict of interest between the Indemnified Party and the Indemnifying Party exists in respect of such claim, then such Indemnified Party shall have the right to participate in the defense of such claim and to employ one firm of attorneys at the Indemnifying Party’s expense to represent such Indemnified Party. No Indemnified Party will consent to entry of any judgment or enter into any settlement without the Indemnifying Party’s written consent to such judgment or settlement, which shall not be unreasonably withheld. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of any judgment or enter into any settlement in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

Section 5.4 Contribution. If the indemnification provided for in this Article V is unavailable or insufficient to hold harmless an Indemnified Party under this Article V, then each Indemnifying Party shall have a joint and several obligation to contribute to the amount paid or payable by such Indemnified Party as a result of the Damages referred to in this Article V in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnified Party on the other hand in connection with the offering which resulted in such Damages, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether an untrue or alleged untrue statement of a material fact or an omission or alleged omission to state a material fact relates to information supplied by the Indemnifying Party or the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statements or omission. BGC Partners and the Holders (in consideration of BGC Partners’ including any Registrable Securities in any Registration Statement filed in accordance with Article II hereof)

-11-

shall be deemed to have agreed, that it would not be just and equitable if contributions pursuant to this Section 5.4 were to be determined by pro rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to in the first sentence of this Section 5.4. The amount paid by an Indemnified Party as a result of the Damages referred to in the first sentence of this Section 5.4 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim (which shall be limited as provided in Section 5.3 if the Indemnifying Party has assumed the defense of any such action in accordance with the provisions thereof) which is the subject of this Section 5.4. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Promptly after receipt by an Indemnified Party under this Section 5.4 of notice of the commencement of any action against such party in respect of which a claim for contribution has been made against an Indemnifying Party under this Section 5.4, such Indemnified Party shall notify the Indemnifying Party in writing of the commencement thereof if the notice specified in Section 5.3 has not been given with respect to such action; provided, however, that the omission so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to any Indemnified Party otherwise under this Section 5.4, except to the extent that the Indemnifying Party is actually materially prejudiced by such failure to give notice, and in no event shall such failure relieve the Indemnifying Party from any other liability which it may have to such Indemnified Party.
