Section 2.2 Exchange Procedures.

(a) Exchange of Units. As promptly as practicable after the Effective Time, Holdco shall cause the Exchange Agent to send to each holder of record of Units as of the Holdings Reorganization Effective Time that were converted pursuant to Section 1.7 into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that risk of loss and title to the Unit Certificates or Uncertificated Units shall pass only upon (A) with respect to Units evidenced by Unit Certificates, delivery of the Unit Certificates (or affidavits of loss in lieu thereof) and (B) with respect to Uncertificated Units, delivery of any such evidence, if any, of the transfer as the Exchange Agent may reasonably request, to the Exchange Agent and shall be in a form and have such other provisions as BGC Partners may reasonably specify) (the “Letter of Transmittal”) and (ii) instructions for use in effecting the surrender of the Unit Certificates or Uncertificated Units.

(b) Upon surrender of a Unit Certificate or Uncertificated Units to the Exchange Agent together with a Letter of Transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Exchange Agent, Holdco shall cause the Exchange Agent to, as promptly as practicable, (i) credit in the stock ledger and other appropriate books and records of Holdco the number of whole shares of the applicable series of Holdco Common Stock into which the Units represented by such Unit Certificates or Uncertificated Units have been converted pursuant to this Agreement, and (ii) pay and deliver to such holder a check in the amount of the cash in lieu of any fractional shares of Holdco Common Stock payable pursuant to Section 2.5 together with any dividends or other distributions to which such Unit Certificates or Uncertificated Units become entitled in accordance with Section 2.3.

(c) In the event of a transfer of ownership of Units that is not registered in the transfer records of BGC Holdings, any shares of Holdco Common Stock to be credited upon, and any cash to be paid upon, due surrender of the Unit Certificate or Uncertificated Units formerly representing such Units, Holdco may cause the Exchange Agent to credit or pay, as the case may be, to such a transferee only if such Unit Certificate or Uncertificated Units are presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence to the satisfaction of Holdco and the Exchange Agent that any applicable stock transfer or similar Taxes have been paid or are not applicable.

(d) Until surrendered as contemplated by this Section 2.2, each Unit Certificate and Uncertificated Unit shall, at any time after the Effective Time, represent the right to receive the Merger Consideration into which the Units represented by such Unit Certificates or Uncertificated Units have been converted pursuant to this Agreement, together with any dividends or other distributions to which such Unit Certificates or Uncertificated Units become entitled in accordance with Section 2.3.

- 14 -

(e) Exchange of BGC Partners Common Stock. Each BGC Partners Certificate shall, from and after the Effective Time and as a result of the Merger, automatically represent an equivalent number of shares of the applicable class of Holdco Common Stock as determined pursuant to Section 1.7(b)(i) or Section 1.7(b)(ii). At the Effective Time, Holdco shall cause the Exchange Agent to credit in the stock ledger and other appropriate books and records of Holdco an equivalent number of shares of the applicable class of Holdco Common Stock for any BGC Partners Book-Entry Shares; provided, however, that if an exchange of BGC Partners Certificates for new certificates is required by Law or applicable rule or regulation, or is desired at any time by Holdco, in its sole discretion, Holdco shall arrange for such exchange on a one-for-one-share basis. For the avoidance of doubt, from and after the Effective Time, the former holders of shares of BGC Partners Common Stock that have been converted into shares of Holdco Common Stock as of the Effective Time pursuant to the Corporate Merger shall be entitled to receive any dividends and distributions that may be made with respect to such shares of Holdco Common Stock with a record date after the Effective Time.

Section 2.3 Distributions with Respect to Unexchanged Units. No dividends or other distributions declared or made with respect to shares of Holdco Common Stock with a record date after the Effective Time shall be paid to the holder of any Unit represented by a Unit Certificate or Uncertificated Unit converted into the right to receive the Merger Consideration pursuant to Section 1.7 until such holder shall surrender such Unit Certificate or Uncertificated Unit in accordance with Section 2.2. Subject to escheat, Tax or other applicable Law, following surrender of any such Unit Certificate or Uncertificated Unit, such holder shall be entitled to receive any such dividends or distributions, without interest, which theretofore had become payable with respect to the Holdco Common Stock represented by such Unit. Such holder shall be entitled to vote after the Effective Time at any meeting of Holdco stockholders with a record date at or after the Effective Time the number of whole shares of the applicable class of Holdco Common Stock represented by such Unit Certificate or Uncertificated Unit, regardless of whether such holder has exchanged their Unit Certificate or Uncertificated Unit for the Merger Consideration.

Section 2.4 No Further Ownership Rights. The shares of Holdco Common Stock issued and cash paid upon conversion of Units and shares of BGC Partners Common Stock in accordance with the terms of Article I and this Article II (including any cash paid pursuant to Section 2.3) shall be deemed to have been delivered or paid in full satisfaction of all rights pertaining to the Units or shares of BGC Partners Common Stock, as applicable. From and after the Effective Time, (a) all holders of Unit Certificates and Uncertificated Units shall cease to have any rights as equityholders of BGC Holdings or the Surviving LLC other than the right to receive the Merger Consideration into which the Units represented by such Unit Certificates or Uncertificated Units have been converted pursuant to this Agreement (together with any dividends or other distributions to which such Unit Certificates or Uncertificated Units become entitled in accordance with Section 2.3), without interest, (b) all holders of BGC Partners Certificates or BGC Partners Book-Entry Shares shall cease to have any rights as stockholders of BGC Partners other than the right to receive the shares of Holdco Common Stock into which the shares represented by such BGC Partners Certificates of BGC Partners Book-Entry Shares have been converted pursuant to this Agreement and (c) the transfer books of the Surviving Corporation and the Surviving LLC shall be closed with respect to all Units and shares of BGC Partners Common Stock outstanding immediately prior to the Effective Time, and there shall be

- 15 -

no further registration of transfers on the transfer books of Holdco, the Surviving Corporation or the Surviving LLC of Units or shares of BGC Partners Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Unit Certificates or Uncertificated Units formerly representing Units or any BGC Partners Certificates or BGC Partners Book-Entry Shares formerly representing shares of BGC Partners Common Stock are presented to Holdco, the Surviving Corporation, the Surviving LLC or the Exchange Agent for any reason, such Unit Certificates, Uncertificated Units, BGC Partners Certificates or BGC Partners Book-Entry Shares (as applicable) shall be cancelled and their holders shall be credited shares of Holdco Common Stock as provided in this Article II (to the extent not previously credited).

Section 2.5 No Fractional Shares of Holdco Common Stock. No fractional shares of Holdco Common Stock shall be issued in the Mergers. Notwithstanding any other provision of this Agreement, each holder that would otherwise have been entitled to receive a fraction of a share of Holdco Common Stock shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional amount multiplied by the volume weighted averages of the trading prices of BGC Partners Class A Common Stock on Nasdaq (as reported by the Wall Street Journal or, if not reported therein, in another authoritative source mutually selected by BGC Partners and BGC Holdings) on the five (5) consecutive Trading Days ending on (and including) the Trading Day that is three (3) Trading Days prior to the date of the Effective Time, rounded down to the nearest penny. The Parties acknowledge that payment of the cash consideration in lieu of issuing fractional shares of Holdco Common Stock was not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Holdco that would otherwise be caused by the issuance of fractional shares of Holdco Common Stock.

Section 2.6 Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Units for six (6) months after the Effective Time shall be delivered to Holdco or otherwise on the instruction of Holdco, and any holders of Unit Certificates or Uncertificated Units that have not theretofore complied with this Article II shall thereafter look only to Holdco (subject to abandoned property, escheat or other similar Laws) as general creditors thereof for the applicable Merger Consideration with respect to the Units formerly represented thereby to which such holders are entitled pursuant to Section 1.7 and any dividends or distributions with respect to shares of Holdco Common Stock to which such holders are entitled pursuant to Section 2.3.

Section 2.7 No Liability. None of Holdco, BGC Partners, BGC Holdings, the BGC Holdings GP, the Surviving Corporation, the Surviving LLC, Merger Sub 1, Merger Sub 2, Holdings Merger Sub or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration or portion of the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any portion of the Exchange Fund that remains undistributed to the holders of Unit Certificates or Uncertificated Units as of immediately prior to the date on which the Exchange Fund would otherwise escheat to, or become the property of, any Governmental Entity shall, to the extent permissible by applicable Law, become the property of Holdco, free and clear of all claims or interest of any Person previously entitled thereto.

- 16 -

Section 2.8 Investment of the Exchange Fund. Any funds included in the Exchange Fund may be invested by the Exchange Agent, as directed by BGC Partners. Any interest and other income resulting from such investments shall promptly be paid to BGC Partners. Any loss of any of the funds included in the Exchange Fund shall be for the account of BGC Partners and shall not alter BGC Partners’ obligation to cause to be paid the Merger Consideration.

Section 2.9 Lost Certificates. If any Unit Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Unit Certificate to be lost, stolen or destroyed and, if required by Holdco, the posting by such Person of a bond in such reasonable amount as Holdco may direct as indemnity against any claim that may be made against it with respect to such Unit Certificate or other documentation (including an indemnity in customary form) reasonably requested by Holdco, the Exchange Agent will take the actions required by this Article II with respect to such lost, stolen or destroyed Unit Certificate with respect to the Units formerly represented thereby, and any unpaid dividends and distributions on shares of Holdco Common Stock deliverable in respect thereof, pursuant to this Agreement.

Section 2.10 Withholding Rights. Each of Holdco, BGC Partners, BGC Holdings, the BGC Holdings GP, the Surviving Corporation, the Surviving LLC, Merger Sub 1, Merger Sub 2, Holdings Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from any Merger Consideration or other amounts otherwise payable pursuant to this Agreement such Merger Consideration or other amounts as are required to be deducted or withheld with respect to the payment of such Merger Consideration or other amounts under the Code (and the Treasury Regulations) or any provision of state, local or non-U.S. Tax Law. To the extent that Merger Consideration or other amounts are so deducted or withheld and, if required, paid over to the relevant taxing authority, such Merger Consideration or other amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

Section 2.11 Further Assurances. From and after the Effective Time, the respective officers of Holdco, the Surviving Corporation and the Surviving LLC, as applicable, will be authorized to execute and deliver, in the name and on behalf of Holdco, BGC Partners, BGC Holdings, the BGC Holdings GP, Merger Sub 1, Merger Sub 2 or Holdings Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Holdco, BGC Partners, BGC Holdings, the BGC Holdings GP, Merger Sub 1, Merger Sub 2 or Holdings Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in Holdco, the Surviving Corporation or the Surviving LLC any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by Holdco, the Surviving Corporation or the Surviving LLC, as applicable, as a result of, or in connection with, the Mergers.

Section 5.6 Tax Matters.

(a) The parties intend that (i) the Corporate Merger and the Holdings Merger, taken together, qualify as a transaction described in Section 351 of the Code and (ii) the Corporate Merger qualify as a “reorganization” within the meaning of Section 368(a) of the Code. Each of Holdco, BGC Partners, BGC Holdings and Cantor will (and will cause its Subsidiaries and Affiliates to) use its reasonable best efforts to cause the Mergers to qualify, and will not take or knowingly fail to take any action (and will cause its Subsidiaries and Affiliates not to take or knowingly fail to take any action) which action or failure to act could reasonably be expected to impede or prevent the Corporate Merger and the Holdings Merger, taken together, from qualifying, as a transaction described in Section 351 of the Code. Each of Holdco, BGC Partners, BGC Holdings and Cantor will (and will cause its Subsidiaries and Affiliates to) use its reasonable best efforts to cause the Corporate Merger to qualify, and will not take or knowingly fail to take any action (and will cause its Subsidiaries and Affiliates not to take or knowingly fail to take any action) which action or failure to act could reasonably be expected to impede or prevent the Corporate Merger from qualifying, as a “reorganization” within the meaning of Section 368(a) of the Code. Subject to the receipt of the opinions referred to in Section 6.2(c) and Section 6.4, each of Holdco, BGC Partners, BGC Holdings and Cantor will (and will cause its Subsidiaries and Affiliates to) file all Tax Returns in a manner consistent with, and take no position inconsistent with, the Tax treatment described in this Section 5.6(a), unless, and then only to the extent, otherwise required pursuant to a final “determination” (within the meaning of Section 1313(a) of the Code or any analogous provisions of applicable Tax Law).

- 29 -

(b) Each of Holdco, BGC Partners, BGC Holdings and Cantor shall (and shall cause its Subsidiaries and Affiliates to) use its reasonable best efforts and will cooperate with the other to (i) finalize, execute and deliver customary tax representation letters that include the representations referred to in Section 6.2(c) and Section 6.4 as of the Closing Date (and, if requested, as of the date of effectiveness of the Form S-4) to Tax Counsel (with a copy to BGC Partners and Cantor) in form and substance reasonably satisfactory to Tax Counsel, BGC Partners and Cantor and (ii) obtain the opinions referred to in Section 6.2(c) and Section 6.4.

(c) Cantor hereby agrees to indemnify, defend and hold harmless BGC Partners to the extent that BGC Partners incurs any income Taxes as a result of (and that would not have been incurred but for) the Mergers (“Indemnified Taxes”); provided that in no event shall Cantor’s aggregate liability to BGC Partners in respect of Indemnified Taxes exceed $10,000,000. Cantor shall pay to BGC Partners an amount equal to any Indemnified Taxes within ten Business Days after written demand from BGC Partners therefor, which demand shall be accompanied by reasonable supporting documentation setting forth a description and calculation of the Indemnified Taxes (the “Demand”). Notwithstanding anything to the contrary in this Agreement, the obligations of Cantor contained in this Section 5.6(c) shall survive until sixty days after the expiration of the applicable statute of limitations (such date, the “SOL Date”); provided that if BGC Partners notifies Cantor in writing of any claim hereunder prior to the SOL Date, the obligations of Cantor contained in this Section 5.6(c) shall survive until the final resolution of such claim. If Cantor objects to the Demand, then, within 30 days after the delivery of such Demand, Cantor shall notify BGC Partners in writing, which notification shall set forth Cantor’s calculation of the Indemnified Taxes (the “Objection”). Cantor and BGC Partners shall use commercially reasonable efforts to resolve such dispute within 30 days. In the event that Cantor and BGC Partners are unable to resolve such dispute within 30 days, Cantor and BGC Partners shall jointly cause an independent accounting firm reasonably acceptable to each (the “Accounting Firm”) to resolve the disputed items promptly, which resolution shall be final and binding upon Cantor and BGC Partners, provided, that the Accounting Firm’s resolution shall in no case result in Cantor’s liability to BGC Partners exceeding the amount set forth in the Demand or being less than the amount set forth in the Objection. The costs, fees and expenses of the Accounting Firm in resolving such dispute shall be borne equally by Cantor and BGC Partners.

Section 5.7 State Takeover Statutes. Each party to this Agreement shall take all reasonable action necessary to ensure that no Takeover Law is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement. If any Takeover Law becomes applicable to this Agreement or any of the transactions contemplated by this Agreement, each party to this Agreement shall take all reasonable action necessary to ensure that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms required by, or provided for, in this Agreement and otherwise to minimize the effect of such Takeover Law on the Mergers and the other transactions contemplated by this Agreement.

Section 5.8 Delisting. BGC Partners shall use its reasonable best efforts to take, or cause to be taken, all actions necessary to delist the BGC Partners Class A Common Stock from Nasdaq and terminate its registration under the Exchange Act as soon as practicable following the Effective Time.

- 30 -

Section 5.9 Nasdaq Listing. Holdco and BGC Partners shall use their reasonable best efforts to cause the shares of Holdco Class A Common Stock to be issued in connection with the Mergers and the shares of Holdco Class A Common Stock to be reserved for issuance upon settlement or exercise of equity awards in respect of Holdco Class A Common Stock to be listed on Nasdaq, subject to official notice of issuance, prior to the Effective Time.

Section 5.10 Cantor Class B Exchange. If Holdco does not issue shares of Holdco Common Stock with an aggregate value of at least $75,000,000 (with the value of each issuance calculated based on the closing market price of Holdco Common Stock on the date of issuance), after the Effective Time and on or prior to the seventh anniversary of the Effective Time (the “Relevant Period”), in connection with mergers, acquisitions and business combinations (including pursuant to equity grants to employees in connection therewith) undertaken by Holdco or any of its Subsidiaries, then Cantor shall cause the applicable members of the Cantor Group to promptly convert a number of shares of Holdco Class B Common Stock equal to the lesser of (a) the Specified Share Number of shares of Holdco Class B Common Stock and (b) the excess of the aggregate amount of shares of Holdco Class B Common Stock held by any member of the Cantor Group as of such time over the Existing Maximum Class B Amount, into shares of Holdco Class A Common Stock on a one-for-one basis. For purposes of this Agreement:

“Specified Share Number” shall mean (a) the number of shares of Holdco Class B Common Stock issued to the members of the Cantor Group in the Holdings Merger pursuant to Section 1.7(c)(i) that is in excess of the Existing Maximum Class B Amount less (b) the aggregate number of shares of Holdco Class B Common Stock, if any, sold or transferred by any member of the Cantor Group to a third party and converted into shares of Holdco Class A Common Stock during the Relevant Period.

“Existing Maximum Class B Amount” shall mean 23.6 million shares of BGC Partners Class B Common Stock.

The Specified Share Number and the Existing Maximum Class B Amount shall be equitably adjusted to take to reflect any stock split, stock dividend, reverse stock split or similar recapitalization with respect to the Holdco Common Stock that occurs during the Relevant Period.

Section 5.11 Termination of Founding Partners. In light of the fact that the Founding Partners shall be “Terminated” under the BGC Holdings LPA once such Founding Partners cease to be Partners of BGC Holdings for any reason, and that the Founding Partners will cease to be Partners of BGC Holdings as a result of the Holdings Reorganization Merger and the Holdings Merger, the parties agree that, unless otherwise consented by Cantor, BGC Holdings GP shall take such actions prior to the Closing as is necessary so that the Founding Partners shall be treated as “Terminated” under the BGC Holdings LPA, so that Cantor may exercise its purchase rights pursuant to Section 12.02(a)(i)(B) and Section 8.08 of the BGC Holdings LPA prior to the Closing as a result of such Termination and with respect to all such Terminated Founding Partners. Unless otherwise consented to by BGC Holdings GP and Cantor, in connection with such Termination, BGC Holdings shall pay to such Founding Partners, as consideration for the redemption of the non-exchangeable Founding Partner Units held by such Founding Partners contemplated by Section 12.02(a)(i)(A) of the BGC Holdings LPA, a number of non-exchangeable HD-Units that are Founding Partner Units equal to the number of non-exchangeable Founding Partner Units that are so redeemed; provided, however, that the foregoing shall not be deemed to change the amount that BGC Holdings is required to pay to redeem or purchase Founding Partner Units for purposes of Section 12.02(a)(i)(B) and Section 8.08 of the BGC Holdings LPA.

-2-

(3) None of the holders of shares of Class A Common Stock or the holders of shares of Class B Common Stock shall have cumulative voting rights.

(b) Dividends; Stock Splits.

(1) Subject to the rights of the holders of shares of any series of Preferred Stock, and subject to any other provisions of this Certificate of Incorporation, holders of shares of Class A Common Stock and shares of Class B Common Stock shall be entitled to receive such dividends and other distributions in cash, stock or property of the Corporation as may be declared thereon by the Board of Directors from time to time out of assets or funds of the Corporation legally available therefor.

(2) If at any time a dividend or other distribution in cash or other property (other than dividends or other distributions payable in shares of Common Stock or other voting securities or options or warrants to purchase shares of Common Stock or other voting securities or securities convertible into or exchangeable for shares of Common Stock or other voting securities) is paid on the shares of Class A Common Stock or the shares of Class B Common Stock, a like dividend or other distribution in cash or other property shall also be paid on shares of Class A Common Stock or shares of Class B Common Stock, as the case may be, in an equal amount per share. If at any time a dividend or other distribution payable in shares of Common Stock or options or warrants to purchase shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock is paid on shares of Class A Common Stock or shares of Class B Common Stock, a like dividend or other distribution shall also be paid on shares of Class A Common Stock or shares of Class B Common Stock, as the case may be; provided, however, that, for this purpose, if shares of Class A Common Stock or other voting securities, or options or warrants to purchase shares of Class A Common Stock or other voting securities or securities convertible into or exchangeable for shares of Class A Common Stock or other voting securities, are paid on shares of Class A Common Stock, and shares of Class B Common Stock or voting securities identical to the other securities paid on the shares of Class A Common Stock (except that voting securities paid on the Class B Common Stock may have up to ten (10) times the number of votes per share as voting securities paid on the Class A Common Stock) or options or warrants to purchase shares of Class B Common Stock or such other voting securities or securities convertible into or exchangeable for shares of Class B Common Stock or such other voting securities, are paid on shares of Class B Common Stock, in an equal amount per share, such dividend or other distribution shall be deemed to be a like dividend or distribution. In the case of any split, subdivision, combination or reclassification of shares of Class A Common Stock or Class B Common Stock, the shares of Class A Common Stock or Class B Common Stock, as the case may be, shall also be split, subdivided, combined or reclassified so that the number of shares of Class A Common Stock and Class B Common Stock outstanding immediately following such split, subdivision, combination or reclassification shall bear the same relationship to each other as did the number of shares of Class A Common Stock and Class B Common Stock outstanding immediately prior to such split, subdivision, combination or reclassification.

-3-

(c) Conversion Rights.

(1) Voluntary Conversion of Class B Common Stock. Each share of Class B Common Stock is convertible into one fully paid and non-assessable share of Class A Common Stock at any time at the option of the holder of such share of Class B Common Stock. In order to exercise the conversion privilege, the holder of any shares of Class B Common Stock to be converted shall present and surrender the certificate or certificates representing such shares (if certificated) during usual business hours at the principal executive offices of the Corporation, or if any agent for the registration or transfer of shares of Class B Common Stock is then duly appointed and acting (said agent being hereinafter called the “Transfer Agent”), then at the office of the Transfer Agent, accompanied by written notice that the holder elects to convert the shares of Class B Common Stock represented by such certificate or certificates (if certificated), to the extent specified in such notice. Such notice shall also state the name or names (with addresses) in which the certificate or certificates for shares of Class A Common Stock which shall be issuable upon such conversion shall be issued. If required by the Corporation, any shares of Class B Common Stock surrendered for conversion shall be accompanied by instruments of transfer, in form satisfactory to the Corporation and the Transfer Agent, duly executed by the holder of such shares or his, her or its duly authorized representative. As promptly as practicable after the receipt of such notice and the surrender of such shares of Class B Common Stock as aforesaid, the Corporation shall issue and deliver at such office to such holder, or on his or her written order, the number of full shares of Class A Common Stock issuable upon the conversion of such shares. Each conversion of shares of Class B Common Stock shall be deemed to have been effected on the date on which such notice shall have been received by the Corporation or the Transfer Agent, as applicable, and, if such shares are evidenced by certificate(s), such certificate(s) representing such shares shall have been surrendered (subject to receipt by the Corporation or the Transfer Agent, as applicable, within thirty (30) days thereafter of any required instruments of transfer as aforesaid), and the person or persons in whose name or names shares of Class A Common Stock shall be issuable upon such conversion shall be deemed to have become on said date the holder or holders of record of the shares represented thereby.

(2) Automatic Conversion of Class B Common Stock. Each share of Class B Common Stock will automatically convert into one (1) share of Class A Common Stock upon any sale, pledge or other transfer (a “Transfer”), whether or not for value, by the initial registered holder thereof, upon any Transfer, other than in each case any Transfer to a Qualified Class B Holder. Notwithstanding anything to the contrary set forth herein, any holder of Class B Common Stock may pledge his, her or its shares of Class B Common Stock to a pledgee pursuant to a bona fide pledge of the shares as collateral security for indebtedness due to the pledgee so long as the shares are not transferred to or registered in the name of the pledgee. In the event of any pledge meeting these requirements, the pledged shares will not be converted automatically into shares of Class A Common Stock. If the pledged shares of Class B Common Stock become subject to any foreclosure, realization or other similar action by the pledgee, they will be converted automatically into shares of Class A Common Stock upon the occurrence of that action.

(3) Unconverted Shares. If less than all of the shares of Class B Common Stock evidenced by a certificate or certificates surrendered to the Corporation (in accordance with such procedures as the Board of Directors may determine) are converted, the Corporation shall execute and deliver to or upon the written order of the holder of such certificate or certificates a new certificate or certificates evidencing the number of shares of Class B Common Stock which are not converted without charge to the holder.

-4-

(4) No Conversion Rights of Class A Common Stock. The Class A Common Stock shall not have any conversion rights.

(5) Reservation of Shares of Class A Common Stock. The Corporation hereby reserves, and shall at all times reserve and keep available, out of its authorized and unissued shares of Class A Common Stock for the purposes of effecting conversions of Class B Common Stock, such number of duly authorized shares of Class A Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Class B Common Stock. The Corporation covenants that all the shares of Class A Common Stock so issuable shall, when so issued, be duly and validly issued, fully paid and non-assessable.

(d) Liquidation, Dissolution, etc. In the event of any liquidation, dissolution or winding up (either voluntary or involuntary) of the Corporation, the holders of shares of Class A Common Stock and the holders of shares of Class B Common Stock shall be entitled to receive the assets and funds of the Corporation available for distribution, after payments to creditors and to the holders of any Preferred Stock of the Corporation that may at the time be outstanding, in proportion to the number of shares held by them, respectively.

(e) Rights Otherwise Identical. Except as expressly set forth in this Certificate of Incorporation, the rights of the holders of Class A Common Stock and the rights of the holders of Class B Common Stock shall be in all respects identical.

SECTION 4. Options, Warrants and Other Rights. The Board of Directors is authorized to create and issue options, warrants and other rights from time to time entitling the holders thereof to purchase securities or other property of the Corporation or any other entity, including any class or series of stock of the Corporation or any other entity and whether or not in connection with the issuance or sale of any securities or other property of the Corporation, for such consideration (if any), at such times and upon such other terms and conditions as may be determined or authorized by the Board of Directors and set forth in one or more agreements or instruments. Among other things and without limitation, such terms and conditions may provide for the following:

(a) adjusting the number or exercise price of such options, warrants or other rights or the amount or nature of the securities or other property receivable upon exercise thereof in the event of a subdivision or combination of any securities, or a recapitalization, of the Corporation, the acquisition by any natural person, company, corporation or similar entity, government, or political subdivision, agency, or instrumentality of a government (each, a “Person”) of beneficial ownership of securities representing more than a designated percentage of the voting power of any outstanding series, class or classes of securities, a change in ownership of the Corporation’s securities or a merger, statutory share exchange, consolidation, reorganization, sale of assets or other occurrence relating to the Corporation or any of its securities, and restricting the ability of the Corporation to enter into an agreement with respect to any such transaction absent an assumption by another party or parties thereto of the obligations of the Corporation under such options, warrants or other rights;

-5-

(b) restricting, precluding or limiting the exercise, transfer or receipt of such options, warrants or other rights by any Person that becomes the beneficial owner of a designated percentage of the voting power of any outstanding series, class or classes of securities of the Corporation or any direct or indirect transferee of such a Person, or invalidating or voiding such options, warrants or other rights held by any such Person or transferee; and

(c) permitting the Board of Directors (or certain directors specified or qualified by the terms of the governing instruments of such options, warrants or other rights) to redeem, terminate or exchange such options, warrants or other rights.

This Section 4 of Article IV shall not be construed in any way to limit the power of the Board of Directors to create and issue options, warrants or other rights.

ARTICLE V

SECTION 1. Meetings of stockholders shall be held at such place, within or without the State of Delaware, as may be designated by or in the manner provided in the Bylaws, or, if not so designated, at the registered office of the Corporation in the State of Delaware. Elections of directors need not be by written ballot unless and to the extent that the Bylaws so provide.

SECTION 2. Any action to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation.

The stockholders may make, adopt, amend, and repeal the Bylaws of the Corporation only with, and in addition to any other vote required by law, the affirmative vote of the holders of a majority of the voting power of all outstanding shares of capital stock of the Corporation present in person or by proxy and entitled to vote thereon.

-6-

ARTICLE VII

EXCULPATION

No director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, respectively, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended. Any repeal or amendment or modification of this Article VII by the stockholders of the Corporation or by changes in applicable law, or the adoption of any provision of this Certificate of Incorporation inconsistent with this Article VII, will, to the extent permitted by applicable law, be prospective only (except to the extent such amendment or change in applicable law permits the Corporation to provide a broader limitation on a retroactive basis than permitted prior thereto), and will not adversely affect any limitation on the personal liability of any director or officer of the Corporation at the time of such repeal or amendment or modification or adoption of such inconsistent provision.

ARTICLE VIII

INDEMNIFICATION AND INSURANCE

SECTION 1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, to the fullest extent permitted by law, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, amounts paid or to be paid in settlement, and excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that, except as provided in this Article VIII, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors. The right to indemnification conferred in this Section 1 of Article VIII shall be a contract right and shall include the right to be paid by the Corporation the expenses, including attorneys’ fees, incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the DGCL requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final

-7-

disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise. The Corporation may, by action of the Board of Directors, provide indemnification to employees and agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers.

SECTION 2. Right of Claimant to Bring Suit. If a claim under Section 1 of Article VIII hereof is not paid in full by the Corporation within thirty (30) days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including the Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including the Board of Directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

SECTION 3. Non-Exclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article VIII shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested directors or otherwise. No amendment or other modification of this Article VIII shall in any way diminish or adversely affect the rights of any director, officer, employee or agent of the Corporation in respect of any occurrence or matter arising prior to any such repeal or modification.

SECTION 4. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

ARTICLE IX

CORPORATE OPPORTUNITY

SECTION 1. To the greatest extent permitted by law and except as otherwise set forth in this Certificate of Incorporation:

(a) None of any Cantor Company or any of their respective Representatives shall owe any fiduciary duty to, nor shall any Cantor Company or any of their respective Representatives be liable for breach of fiduciary duty to, the Corporation or any of its stockholders. In taking any action, making any decision or exercising any discretion with respect to the Corporation, each Cantor Company and their respective Representatives shall be entitled to consider such interests and factors as it desires, including its own interests and those of its Representatives, and shall have no duty or obligation (i) to give any consideration to the interests of or factors affecting the Corporation, the Corporation’s stockholders or any other person, or (ii) to abstain from participating in any vote or other action of the Corporation, or any board, committee or similar body of any of the foregoing. None of any Cantor Company or any of their respective Representatives shall violate a duty or obligation to the Corporation merely because such person’s conduct furthers such person’s own interest, except as specifically set forth in Section 1(c) of this Article IX. Any Cantor Company or any of their respective Representatives may lend money to, and transact other business with, the Corporation and its Representatives. The rights and obligations of any such person who lends money to, contracts with, borrows from or transacts business with the Corporation or any of its Representatives are the same as those of a person who is not involved with the Corporation or any of its Representatives, subject to other applicable law. No transaction between any Cantor Company or any of their respective Representatives, on the one hand, with the Corporation or any of its Representatives, on the other hand, shall be voidable solely because any Cantor Company or any of their respective Representatives has a direct or indirect interest in the transaction. Nothing herein contained shall prevent any Cantor Company or any of their respective Representatives from conducting any other business, including serving as an officer, director, employee, or stockholder of any corporation, partnership or limited liability company, a trustee of any trust, an executor or administrator of any estate, or an administrative official of any other business or not-for-profit entity, or from receiving any compensation in connection therewith.

(b) None of any Cantor Company or any of their respective Representatives shall owe any duty to refrain from (i) engaging in the same or similar activities or lines of business as the Corporation and its Representatives, or (ii) doing business with any of the Corporation’s or its Representatives’ clients or customers. In the event that any Cantor Company or any of their respective Representatives acquires knowledge of a potential transaction or matter that may be a Corporate Opportunity for any Cantor Company or any of their respective Representatives, on the one hand, and the Corporation or any of its Representatives, on the other hand, such Cantor Company or Representatives, as the case may be, shall have no duty to communicate or offer such Corporate Opportunity to the Corporation or any of its Representatives, subject to Section 1(c) of this Article IX. None of any Cantor Company or any of their respective Representatives shall be liable to the Corporation, any of its stockholders or any of its Representatives for breach of any fiduciary duty by reason of the fact that any Cantor Company or any of their respective Representatives pursues or acquires such Corporate Opportunity for itself, directs such Corporate Opportunity to another person or does not present such Corporate Opportunity to the Corporation or any of its Representatives, subject to Section 1(c) of this Article IX.

-9-

(c) If a third party presents a Corporate Opportunity to a person who is both a Representative of the Corporation and a Representative of a Cantor Company, expressly and solely in such person’s capacity as a Representative of the Corporation, and such person acts in good faith in a manner consistent with the policy that such Corporate Opportunity belongs to the Corporation, then such person (i) shall be deemed to have fully satisfied and fulfilled any fiduciary duty that such person has to the Corporation as a Representative of the Corporation with respect to such Corporate Opportunity, (ii) shall not be liable to the Corporation, any of its stockholders or any of its Representatives for breach of fiduciary duty by reason of such person’s action or inaction with respect to such Corporate Opportunity, (iii) shall be deemed to have acted in good faith and in a manner that such person reasonably believed to be in, and not opposed to, the Corporation’s best interests, and (iv) shall be deemed not to have breached such person’s duty of loyalty to the Corporation and its stockholders and not have derived an improper personal benefit therefrom; provided that a Cantor Company or any of its Representatives may pursue such Corporate Opportunity if the Corporation shall decide not to pursue such Corporate Opportunity. If a Corporate Opportunity is not presented to a person who is both a Representative of the Corporation and a Representative of a Cantor Company and, expressly and solely in such person’s capacity as a Representative of the Corporation, such person shall not be obligated to present such Corporate Opportunity to the Corporation or to act as if such Corporate Opportunity belongs to the Corporation, and such person shall (i) be deemed to have fully satisfied and fulfilled any fiduciary duty that such person has to the Corporation as a Representative of the Corporation with respect to such Corporate Opportunity, (ii) shall not be liable to the Corporation, any of its stockholders or any of its Representatives for breach of fiduciary duty by reason of such person’s action or inaction with respect to such Corporate Opportunity, (iii) shall be deemed to have acted in good faith and in a manner that such person reasonably believed to be in, and not opposed to, the Corporation’s best interests, and (iv) shall be deemed not to have breached such person’s duty of loyalty to the Corporation and its stockholders and not to have derived an improper personal benefit therefrom.

(d) For purposes of this Article IX:

(1) “Cantor Company” means Cantor and any of its affiliates (other than, if applicable, the Corporation and its affiliates).

(2) “Corporate Opportunity” means any business opportunity that the Corporation is financially able to undertake, that is, from its nature, in the Corporation’s lines of business, is of practical advantage to the Corporation and is one in which the Corporation has an interest or a reasonable expectancy, and in which, by embracing the opportunities, the self-interest of Cantor or their respective Representatives will be brought into conflict with the Corporation’s self-interest.

(3) “Representatives” means, with respect to any person, the directors, officers, employees, general partners or managing member of such person.

SECTION 2. Neither the alteration, amendment, termination, expiration or repeal of this Article IX nor the adoption of any provision inconsistent with this Article IX shall eliminate or reduce the effect of this Article IX in respect of any matter occurring, or any cause of action that, but for this Article IX, would accrue or arise, prior to such alteration, amendment, termination, expiration, repeal or adoption.

Nominations of persons for election to the Board of Directors of the Corporation and the proposal of business to be considered by the stockholders may be made at an annual meeting of stockholders by or at the direction of the Board of Directors or by any stockholder of the Corporation who was a stockholder of record on the record date established for the giving of notice of such meeting, who is entitled to vote at the meeting and who complies with the notice procedures set forth in these Bylaws.

For nominations or other business to be properly brought by a stockholder, the stockholder must have given timely advance notice in writing to the Secretary of the Corporation. To be timely, a stockholder’s notice shall be delivered to, or mailed and received at, the principal executive offices of the Corporation (i) with respect to an annual meeting of the stockholders of the Corporation, not later than the close of business on the one hundred and twentieth (120th) day prior to the first anniversary of the date of the Corporation’s proxy statement for the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is more than thirty (30) days before or more than sixty (60) days after such anniversary date, notice by the stockholder to be timely must be so delivered not later than the close of business on the later of the one hundred and twentieth (120th) day prior to the date of such proxy statement or the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the Corporation; and (ii) with respect to a special meeting of stockholders of the Corporation for the election of Directors, not later than the close of business on the tenth (10th) day following the day on which notice of the date of the special meeting was mailed to stockholders of the Corporation as provided in Section 4 of this Article II hereof or public disclosure of the date of the special meeting was made, whichever first occurs. Any such notice to be given by a stockholder shall set forth: (a) as to each person whom the stockholder proposes to nominate for election as a Director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-11 thereunder (including such person’s written consent to being named in any proxy statement

2

relating to the Corporation’s next annual meeting or special meeting, as applicable, and to serve as a Director if elected); (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of such business, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made, (x) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner and (y) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner.

Only such persons who are nominated in accordance with the procedures set forth in these Bylaws shall be eligible to serve as Directors and only such business shall be conducted at a meeting of the stockholders as shall have been brought before the meeting in accordance with these Bylaws. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the Chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made or proposed, as the case may be, in accordance with the procedures set forth herein and, if any proposed nomination or business is not in compliance with procedures set forth herein, to declare that such defective proposal or nomination shall be disregarded.

Nothing herein shall be deemed to limit or restrict the procedures required to be followed in connection with stockholder proposals to be brought before a meeting of stockholders pursuant to Regulation 14A under the Exchange Act and Rule 14a-8 thereunder.

SECTION 4. Notice of Meetings. Except as otherwise provided in these Bylaws or by law, a written notice of each meeting of the stockholders shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder of the Corporation entitled to vote at such meeting at the stockholder’s address as it appears on the records of the Corporation or by a form of electronic transmission to which the stockholder has consented. The notice shall state the place, date and hour of the meeting and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and may vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. If mailed, such notice shall be deemed to be given when deposited in the United States mail, postage prepaid, directed to a stockholder at his or her address as it appears on the records of the Corporation.

SECTION 6. Adjourned Meetings. Whether or not a quorum shall be present in person or represented at any meeting of the stockholders, the holders of a majority of the voting power of all outstanding shares of stock of the Corporation present in person or represented by proxy and entitled to vote at such meeting may adjourn from time to time; provided, however, that if the holders of any class of stock of the Corporation are entitled to vote separately as a class upon any matter at such meeting, any adjournment of the meeting in respect of action by such class upon such matter shall be determined by the holders of a majority of the voting power of all outstanding shares of such class present in person or represented by proxy and entitled to vote at such meeting. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place, if any, thereof, or the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and may vote at such adjourned meeting, are announced at the meeting at which the adjournment is taken or are otherwise publicly announced or disclosed. At the adjourned meeting, the stockholders, or the holders of any class of stock entitled to vote separately as a class, as the case may be, may transact any business which might have been transacted by them at the original meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the adjourned meeting. The Board of Directors may postpone any meeting of stockholders or cancel any special meeting of stockholders by public announcement or disclosure prior to the time scheduled for the meeting.

SECTION 7. Organization. The Chairman of the Board; or, in the absence of the Chairman of the Board, a Chief Executive Officer; or, in the absence of a Chief Executive Officer, a President; or, in the absence of the Chairman of the Board, a Chief Executive Officer and a President, a Vice Chairman, a Chief Operating Officer or a Vice President shall call all meetings of the stockholders to order, and shall act as Chairman of such meetings. In the absence of the Chairman of the Board and all of the Chief Executive Officers, the Presidents, the Vice Chairman, the Chief Operating Officers and the Vice Presidents, the holders of a majority of the voting power of the outstanding shares of stock of the Corporation present in person or represented by proxy and entitled to vote at such meeting shall elect a Chairman.

The Secretary of the Corporation shall act as secretary of all meetings of the stockholders; but in the absence of the Secretary, the chairman of the meeting may appoint any person to act as secretary of the meeting. It shall be the duty of the Secretary of the Corporation to prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of stockholders entitled to vote at such meeting, arranged in alphabetical order and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting or, if not so specified, at the place where the meeting is to be held, for the ten (10) days next preceding the meeting, to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours.

SECTION 8. Voting. Except as otherwise provided in the Certificate of Incorporation or by law, each stockholder shall be entitled to one vote for each share of the capital stock of the Corporation registered in the name of such stockholder upon the books of the Corporation. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to

4

corporate action in writing without a meeting may authorize another person or persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. When directed by the presiding officer or upon the demand of any stockholder, the vote upon any matter before a meeting of stockholders shall be by ballot. Except as otherwise provided by law or by the Certificate of Incorporation, (a) Directors shall be elected by a plurality of the voting power present in person or represented by proxy at a meeting of stockholders by the stockholders entitled to vote in the election, and (b) whenever any corporate action, other than the election of Directors is to be taken, it shall be authorized by a majority of the votes cast at a meeting of stockholders by the stockholders entitled to vote thereon.

Shares of the capital stock of the Corporation belonging to the Corporation or to another corporation, if a majority of the shares entitled to vote in the election of Directors of such other corporation is held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted for quorum purposes.

SECTION 9. Inspectors of Election; Opening and Closing the Polls. When required by law or directed by the presiding officer or upon the demand of any stockholder entitled to vote, but not otherwise, the polls shall be opened and closed, the proxies and ballots shall be received and taken in charge, and all questions touching the qualification of voters, the validity of proxies and the acceptance or rejection of votes shall be decided at any meeting of the stockholders by one or more Inspectors of Election who may be appointed by the Board of Directors before the meeting, or if not so appointed, shall be appointed by the presiding officer at the meeting. If any person so appointed fails to appear or act, the vacancy may be filled by appointment in like manner. The chairman of the meeting may fix and announce at the meeting the date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting.

SECTION 10. Stockholder Action by Written Consent. Any action to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing (which may be a telecopy, telegram, cablegram or other electronic transmission), setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation. To be written, signed and dated for the purpose of these Bylaws, a telegram, cablegram or other electronic transmission shall set forth or be delivered with information from which the Corporation can determine (i) that it was transmitted by a stockholder or proxy holder or a person authorized to act for a stockholder or proxy holder, and (ii) the date on which it was transmitted, such date being deemed the date on which the consent was signed. Prompt notice of the taking of any corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

Vacancies caused by any such removal and not filled by the stockholders at the meeting at which such removal shall have been made, or any vacancy caused by the death or resignation of any Director or for any other reason, and any newly created Directorship resulting from any increase in the authorized number of Directors, may be filled by the affirmative vote of a majority of the Directors then in office, although less than a quorum, and any Director so elected to fill any such vacancy or newly created Directorship shall hold office until his or her successor is elected and qualified or until his or her earlier resignation or removal.

When one or more Directors shall resign effective at a future date, a majority of the Directors then in office, including those who have so resigned, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each Director so chosen shall hold office as herein provided in connection with the filling of other vacancies.

ARTICLE V

INDEMNIFICATION OF OFFICERS AND DIRECTORS

SECTION 1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law (“DGCL”), as the same exists or may hereafter be amended (but, in the case of any such amendment, to the fullest extent permitted by law, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, amounts paid or to be paid in settlement, and excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that, except as provided in this Article V, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors. The right to indemnification conferred in this Section 1 of Article V shall be a contract right and shall include the right to be paid by the Corporation the expenses, including attorneys’ fees, incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the DGCL requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise. The Corporation may, by action of the Board of Directors, provide indemnification to employees and agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers.

SECTION 2. Indemnification Requests. To obtain indemnification under this Article V, a claimant shall submit to the Corporation a written request, including therein or therewith such documentation and information as are reasonably available to the claimant and are reasonably necessary to determine whether and to what extent the claimant is entitled to indemnification. Upon written request by a claimant for indemnification pursuant to the first sentence of this Section 2 of Article V, a determination, if required by applicable law, with respect to the claimant’s entitlement thereto shall be made as follows: (1) if requested by the claimant, by Independent Counsel (as hereinafter defined), or (2) if no request is made by the claimant for a determination by Independent Counsel, (i) by the Board of Directors by a majority vote of a quorum consisting of Disinterested Directors (as hereinafter defined), or (ii) if a quorum of the Board of Directors consisting of Disinterested Directors is not obtainable or, even if obtainable, such quorum of Disinterested Directors so directs, by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the claimant, or (iii) if a quorum of Disinterested Directors so directs, by the stockholders of the Corporation. In the event that the determination of entitlement to indemnification is to be made by Independent Counsel at the

12

request of the claimant, the Independent Counsel shall be selected by the Board of Directors unless there shall have occurred within two years prior to the date of the commencement of the action, suit or proceeding for which indemnification is claimed a “Change of Control” as defined in the 1999 Long-Term Incentive Plan of eSpeed, Inc., in which case the Independent Counsel shall be selected by the claimant unless the claimant shall request that such selection be made by the Board of Directors. If it is so determined that the claimant is entitled to indemnification, payment to the claimant shall be made within ten (10) days after such determination.

SECTION 3. Right of Claimant to Bring Suit. If a claim under Section 1 of this Article V is not paid in full by the Corporation within thirty (30) days after a written claim pursuant to Section 2 of this Article V has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than it permitted the Corporation to provide prior to such amendment) for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

SECTION 4. Binding Determination. If a determination shall have been made pursuant to Section 2 of this Article V hereof that the claimant is entitled to indemnification, the Corporation shall be bound by such determination in any judicial proceeding commenced pursuant to Section 3 of this Article V hereof.

SECTION 5. Preclusion. The Corporation shall be precluded from asserting in any judicial proceeding commenced pursuant to Section 3 of this Article V that the procedures and presumptions of this Article V are not valid, binding and enforceable and shall stipulate in such proceeding that the Corporation is bound by all the provisions of this Article V.

SECTION 6. Non-Exclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article V shall not be exclusive of any other right that any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise. No amendment or other modification of this Article V shall in any way diminish or adversely affect the rights of any director, officer, employee or agent of the Corporation in respect of any occurrence or matter arising prior to any such repeal or modification.

13

SECTION 7. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL. To the extent that the Corporation maintains any policy or policies providing such insurance, each such director or officer, and each such agent or employee to which rights to indemnification have been granted as provided in Section 8 of this Article V shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage thereunder for any such director, officer, employee or agent.

SECTION 8. Indemnification for Employees and Agents. The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and rights to be paid by the Corporation the expenses incurred in defending any proceeding in advance of its final disposition, to any employee or agent of the Corporation to the fullest extent of the provisions of this Article V with respect to the indemnification and advancement of expenses of directors and officers of the Corporation.

SECTION 9. Illegality. If any provision or provisions of this Article V shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Article V (including, without limitation, each portion of this Article V containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Article V (including, without limitation, each such portion of this Article V containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

SECTION 10. Definitions. For purposes of this Article V:

(1) “Disinterested Director” means a director of the Corporation who is not and was not a party to the matter in respect of which indemnification is sought by the claimant.

(2) “Independent Counsel” means a law firm, a member of a law firm, or an independent practitioner that is experienced in matters of corporation law and shall include any person who, under the applicable standards of professional conduct then prevailing, would not have a conflict of interest in representing either the Corporation or the claimant in an action to determine the claimant’s rights under this Article V.

SECTION 11. Notices. Any notice, request or other communication required or permitted to be given to the Corporation under this Article V shall be in writing and either delivered in person or sent by telecopy, telex, telegram, overnight mail or courier service, or certified or registered mail, postage prepaid, return receipt requested, to the Secretary of the Corporation and shall be effective only upon receipt by the Secretary.

In case any officer or officers who shall have signed any such certificate or certificates shall cease to be such officer or officers of the Corporation, whether because of death, resignation, removal or otherwise, before such certificate or certificates shall have been delivered by the Corporation, such certificate or certificates may nevertheless be issued and delivered as though the person or persons who signed such certificate or certificates had not ceased to be such officer or officers of the Corporation.

All certificates for shares of stock shall be consecutively numbered as the same are issued. The name of the person owning the shares represented thereby with the number of such shares and the date of issue thereof shall be entered on the books of the Corporation.

Except as hereinafter provided, all certificates surrendered to the Corporation for transfer shall be canceled, and no new certificates shall be issued until former certificates for the same number of shares have been surrendered and canceled.

SECTION 2. Lost, Stolen or Destroyed Certificates. Whenever a person owning a certificate for shares of stock of the Corporation alleges that it has been lost, stolen or destroyed, he or she shall file in the office of the Corporation an affidavit setting forth, to the best of his or her knowledge and belief, the time, place and circumstances of the loss, theft or destruction, and, if required by the Board of Directors, a bond of indemnity or other indemnification sufficient in the opinion of the Board of Directors to indemnify the Corporation and its agents against any claim that may be made against it or them on account of the alleged loss, theft or destruction of any such certificate or the issuance of a new certificate in replacement therefor. Thereupon the Corporation may cause to be issued to such person a new certificate in replacement for the certificate alleged to have been lost, stolen or destroyed. Upon the stub of every new certificate so issued shall be noted the fact of such issue and the number, date and the name of the registered owner of the lost, stolen or destroyed certificate in lieu of which the new certificate is issued.

SECTION 3. Transfer of Shares. Shares of stock of the Corporation shall be transferred on the books of the Corporation by the holder thereof, in person or by his or her attorney duly authorized in writing, and in the case of shares of stock represented by certificates, upon surrender and cancellation of such certificates for the number of shares of stock to be transferred, except as provided in Section 2 of this Article VI.

If no record date is fixed, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the day on which the first written consent is delivered to the Corporation; and the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

SECTION 6. Dividends. Subject to the provisions of the Certificate of Incorporation, the Board of Directors shall have power to declare and pay dividends upon shares of stock of the Corporation, but only out of funds available for the payment of dividends as provided by law.

9. Miscellaneous.

9.1 Governing Law: Jurisdiction. This Agreement shall be construed, performed and enforced in accordance with, and governed by, the Laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder, brought by another party hereto or its successors or assigns shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, any other state or federal court within the State of Delaware. Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the courts set forth in this paragraph and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than such courts. Each of the parties hereto hereby irrevocably waives, and

agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that is not personally subject to the jurisdiction of the above named courts, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts and (iii) to the fullest extent permitted by applicable Law, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each of the parties hereto agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. To the fullest extent permitted by applicable Law, each of the parties hereto hereby consents to the service of process in accordance with Section 9.4; provided that nothing herein shall affect the right of any party to serve legal process in any other matter permitted by Law.

9.2 Assignment; Successors and Assigns; No Third Party Rights. No party hereto shall assign this Agreement or any rights or obligations hereunder without the prior written consent of the other parties hereto, and any such attempted assignment without such prior written consent shall be void and of no force and effect. This Agreement shall inure to the benefit of and shall be binding upon the successors and permitted assigns of the parties hereto. Nothing in this Agreement is intended to confer, or does confer, any rights or remedies under or by reason of this Agreement on any Persons other than the parties hereto and their respective successors and permitted assigns.

9.3 Amendments and Waivers.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of BGC Partners and Cantor. Any agreement on the part of a party hereto to any waiver shall be valid only if set forth in a written instrument signed on behalf of such party (including, in the case of BGC Partners, the Joint Committee). The failure or delay of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights, nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

All notices, requests, instructions or other communications or documents to be given or made hereunder by any party hereto to the other parties hereto shall be in writing and (a) served by personal delivery upon the party for whom it is intended, (b) by an internationally recognized overnight courier service upon the party for whom it is intended or (c) sent by email, provided that the transmission of the email is promptly confirmed:

9.6 Interpretation. The section and paragraph headings in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement. If a term is defined as one part of speech (such as a noun), it shall have a corresponding meaning when used as another part of speech (such as a verb). Unless the context of this Agreement clearly requires otherwise, words imparting the masculine gender shall include the feminine and neutral genders and vice versa, and the definitions of terms contained in this Agreement are applicable to the singular as well as the plural forms of such terms. The words “includes” or “including” shall mean “including without limitation.” The words “hereof,” “hereby,” “herein,” “hereunder” and similar terms in this Agreement shall refer to this Agreement as a whole and not any particular section or article in which such words appear, the word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends and such phrase shall not mean simply “if.” Any reference to a Law shall include any rules and regulations promulgated thereunder, and shall mean such Law as from time to time amended, modified or supplemented. References herein to any contract (including this Agreement) mean such contract as amended, supplemented or modified from time to time in accordance with the terms thereof.

9.7 Entire Agreement; No Other Representations. This Agreement and the Corporate Conversion Agreement contain the entire understanding among the parties hereto with respect to the matters contemplated hereby and supersede and replace all prior and contemporaneous agreements and understandings, oral or written, with regard to such matters.

9.8 Severability; Construction.

(a) In the event that any part of this Agreement is declared by any court or other judicial or administrative body to be null, void or unenforceable, and all of the other provisions of this Agreement shall remain in full force and effect, with no effect on the validity or enforceability of such other provisions. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (i) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (ii) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.

(b) The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If any ambiguity or question of intent arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement.

9.9 Counterparts. This Agreement may be executed in counterparts, (including by facsimile, “.pdf” files or other electronic transmission) each of which shall be deemed an original, but all of which when taken together shall constitute the same instrument.

9.10 Expenses. All expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such expenses.

9.11 Action by BGC Partners. Actions taken under this Agreement on behalf of BGC Partners will be taken only with the approval of the Joint Committee.

9.12 Injunctive Relief. The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that BGC Partners shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 9.1, without proof of actual damages (and Cantor hereby waives any requirement for the securing or posting of any bond in connection with any such remedy), this being in addition to any other remedy to which BGC Partners is entitled at law or in equity. Cantor further agrees not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, or to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.
