(a) In addition to the actions specifically provided for in this Agreement, each Party shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary, proper or advisable under Applicable Law, regulations and agreements to consummate and make effective the transactions contemplated hereby. Without limiting the foregoing, each Party shall cooperate with the other Party, and execute and deliver, or use its reasonable best efforts to cause to be executed and delivered, all

instruments, including instruments of conveyance, assignment and transfer, and to make all filings with, and to obtain all consents, approvals or authorizations of, any Governmental Authority or any other Person under any permit, license, agreement, indenture or other instrument, and take all such other actions as such Party may reasonably be requested to take by any other Party from time to time, consistent with the terms hereof, in order to effectuate the provisions and purposes of this Agreement and the transactions contemplated hereby.

(b) Subject to Section 4.01(c) hereof, if at any time or from time to time after the Closing Date, (i) Cantor or any of its Subsidiaries shall possess a Transferred Asset or (ii) BGC Partners or any of its Subsidiaries shall possess an Excluded Asset, then Cantor or BGC Partners, as the case may be, shall promptly transfer, or cause to be transferred, such Asset to BGC Partners or Cantor, as the case may be. Prior to any such transfer, the Party possessing such Asset shall hold such Asset in trust for the use and benefit of the Party entitled thereto (at the expense of the Party entitled thereto), and shall take such other actions as may be reasonably requested by the Party to which such Asset is to be transferred in order to place such Party, insofar as reasonably possible, in the same position it would have been had such Asset been transferred at the Effective Time.

(c) Without limiting the generality of Section 4.01(a) or Section 4.01(b), if the valid, complete and perfected assignment or transfer to BGC Partners of any Transferred Assets or Transferred Liabilities to be transferred under this Agreement or any Ancillary Agreement requires the consent, agreement or approval of or any filing or registration with any Person or Governmental Authority, and as a result of the failure to make or obtain any such consent, agreement, approval, filing or registration such transfer is not effected as contemplated hereby or thereby despite the provisions hereof purporting to effect such assignment or transfer, then, (i) the Parties shall cooperate to effect such transfer as promptly following the Closing as is practicable, and (ii) until such time as any impediment to the validity, completeness or perfection of such assignment or transfer shall have been removed, nullified or waived, the Person possessing such Transferred Asset or Transferred Liability shall hold such Transferred Asset or Transferred Liability in trust for the use and benefit of the Person entitled thereto (at the expense of the Person entitled thereto), and shall take such other action as may be reasonably requested by the Person to whom such Transferred Asset or Transferred Liability is to be transferred in order to place such Person, insofar as reasonably possible, in the same position it would have been had such Transferred Asset or Transferred Liability been transferred on the Effective Time.

(d) Without limiting the generality of Section 4.01(a), prior to the Effective Time, Cantor, as the sole stockholder of BGC Partners, shall ratify any actions that are necessary, proper or desirable to be taken by BGC Partners to effectuate the transactions contemplated hereby in a manner consistent with the terms hereof.

The Parties intend that any transfer of Information that would otherwise be within the attorney-client privilege shall not operate as a waiver of any potentially applicable privilege. Each Party shall make its employees and facilities available and accessible during normal business hours and on reasonable prior notice to provide an explanation of any Information provided hereunder.

(b) Notwithstanding anything to the contrary in Section 4.02(a), after the Effective Time, Cantor shall provide, or cause to be provided, to BGC Partners in such form as BGC Partners shall request, at no charge to BGC Partners, all financial and other data and Information in the possession or under the control of Cantor or any of its Subsidiaries as BGC Partners determines necessary or advisable in order to prepare BGC Partners’ and its Subsidiaries’ financial statements or any other reports, filings or submissions of BGC Partners and its Subsidiaries with any Governmental Authority.

(c) Any Information owned by one Person that is provided to a requesting Party pursuant to this Section 4.02 shall be deemed to remain the property of the providing Person (or Person on whose behalf such Information is being provided).

creating, gathering and copying such Information, to the extent that such costs are incurred for the benefit of the requesting Party by or on behalf of such other Party or its Representatives or Subsidiaries, if applicable. Except as may be otherwise specifically provided elsewhere in this Agreement or in any other Ancillary Agreement, such costs shall be computed in accordance with the providing Party’s standard methodology and procedures.

(e) To facilitate the possible exchange of Information pursuant to this Section 4.02 and other provisions of this Agreement after the Effective Time, the Parties agree to use their reasonable best efforts to retain all Information in their respective possession or control at the Effective Time in accordance with the policies of Cantor as in effect at the Effective Time.

(f) No Party shall have any Liability to the other Party in the event that any Information exchanged or provided pursuant to this Agreement that is an estimate or forecast, or which is based on an estimate or forecast, is found to be inaccurate, in the absence of willful misconduct or fraud by the Party providing such Information. No Party shall have any Liability to the other Party if any Information is destroyed after using its reasonable best efforts in accordance with the provisions of Section 4.02(e).

The requesting Party shall bear all out-of-pocket costs and expenses (including allocated costs of in-house counsel and other personnel) in connection therewith.

(b) If an indemnifying party chooses to defend or to seek to compromise or settle any Third-Party Claim, each Party shall use its reasonable best efforts to make available to the other Party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of such Party and, if applicable, its Subsidiaries as witnesses and any books, records or other documents within its control or which it otherwise has the ability to make available during normal business hours, to the extent that any such Person

(giving consideration to business demands of such directors, officers, employees, other personnel and agents) or books, records or other documents may reasonably be required (and, in the case of any such Person, for reasonable periods of time) in connection with such defense, settlement or compromise, as the case may be, and shall otherwise cooperate in such defense, settlement or compromise, as the case may be, in each case at the indemnifying party’s expense. The indemnifying party shall bear all out-of-pocket costs and expenses (including allocated costs of in-house counsel and other personnel) in connection therewith.

(e) The obligation of the Parties to provide witnesses pursuant to this Section 4.03 is intended to be interpreted in a manner so as to facilitate cooperation and shall include the obligation to provide as witnesses, directors, officers, employees, other personnel and agents without regard to whether any such individual could assert a possible business conflict (subject to the exception set forth in the first sentence of Section 4.03(a)).

(f) For a period of three years from the Closing Date, Cantor agrees to retain and not destroy or dispose of books, records and other data of the BGC Business prior to the Closing to the extent not transferred to BGC Partners or its Subsidiaries and, prior to destroying or disposing of such books, records and other data, to notify BGC Partners and, at the request of BGC Partners, to transfer such books, records and other data to BGC Partners to the extent that such books, records and other data can, without unreasonable effort or expense, be separated from books and records maintained by Cantor or any of its Subsidiaries in connection with businesses other than the Transferred Businesses (unless BGC Partners shall pay for the full amount of the costs and expenses associated with such separation).

(a) Subject to Section 4.05 and unless otherwise agreed by the Party to whom such Covered Information relates, each of the Parties agrees to hold, and to cause each member of its respective Affiliates, directors, officers, employees, general partners, agents, accountants, managing member, employees, counsel and other advisors and representatives (collectively,

“Representatives”) to hold, in strict confidence, with at least the same degree of care that applies to Cantor’s confidential and proprietary Information pursuant to policies in effect as of the date hereof, all Information concerning each such other Party (including such Person’s clients, transactions, business, Assets, Liabilities, performance or operations) that is either in its possession (including Information in its possession prior to the date hereof) or furnished by any such other Party or its Representatives at any time pursuant to this Agreement, any Ancillary Agreement or otherwise (collectively, “Covered Information”), except that the following shall not be deemed to be Covered Information: any such Information to the extent that (i) at the time of disclosure such Information is generally available to and known by the public (other than as a result of a disclosure by the disclosing Party or by any of its Representatives in breach of this Section 4.04) or (ii) such Information has after the Effective Time been lawfully acquired from other sources by such Party on a non-public basis which sources are, to the knowledge of the Party acquiring such Information, not themselves bound by a contractual, legal or fiduciary obligation that would limit or prohibit disclosure of such Information.

(b) Subject to Section 4.05 and unless otherwise agreed by the Party to whom such Covered Information relates, each Party agrees (i) not to use any Covered Information other than for such purposes as shall be expressly permitted hereunder or under any Ancillary Agreement and (ii) not to release or disclose, or permit to be released or disclosed, any Covered Information to any other Person, except its Representatives who need to know such Covered Information (who shall be advised of their obligations hereunder with respect to such Covered Information), except in compliance with Section 4.05. Without limiting the foregoing, when any Covered Information is no longer needed for the purposes contemplated by this Agreement or any Ancillary Agreement, each Party will promptly after request of the Party that provided such Covered Information either return to such Party all such Covered Information in a tangible form (including all copies thereof and all notes, analyses, presentations, extracts or summaries based thereon) or certify to the other Party that it has destroyed such Covered Information (and such copies thereof and such notes, extracts, analyses, presentations or summaries based thereon). Notwithstanding the return or destruction of the Covered Information, such Party will continue to be bound by its obligations of confidentiality and other obligations hereunder.

SECTION 4.05 Protective Arrangements. In the event that any Party or any of its Subsidiaries determines on the advice of its counsel that it is required to disclose any Covered Information of any other Party (or any of such Party’s Subsidiaries) pursuant to Applicable Law or receives any demand under lawful process or from any Governmental Authority to disclose or provide Covered Information of any other Party (or any of such Party’s Subsidiaries), such Party shall, to the extent practicable and unless otherwise required by Applicable Law, notify the other Party prior to disclosing or providing such Covered Information and shall cooperate at the expense of the requesting Party in seeking any reasonable protective arrangements requested by such other Party. Subject to the foregoing, the Person that received such request may thereafter disclose or provide Covered Information if and to the extent required by such Applicable Law (as so advised by counsel) or by lawful process of such Governmental Authority; provided, however, that the Person shall only disclose such portion of the Covered Information so required to be disclosed or provided.

SECTION 4.06 Intercompany Agreements. All Contracts, licenses, commitments or other arrangements, formal or informal, written or oral and whether express or implied,

between any of Cantor or any other Cantor Company, on the one hand, and any Transferred Entity, on the other hand, set forth on Schedule 4.06, shall terminate effective as of the Effective Time, and no Persons party to any such Contract, license, commitment or other arrangement shall have any rights under such Contract, license, commitment or arrangement.

SECTION 4.07 Guarantee Obligations. The Parties shall cooperate, and shall cause their respective Subsidiaries to cooperate, to terminate, or to cause BGC Partners or its Subsidiaries (or a Transferred Entity) to be substituted in all respects for Cantor or a Cantor Company in respect of all obligations of Cantor or a Cantor Company under any of the Transferred Liabilities for which Cantor or a Cantor Company may be liable, as guarantor, original tenant, primary obligor or otherwise, except, in each case, for the Indebtedness Guarantees and any Excluded Liability. If such a termination or substitution is not effected by the Effective Time, (i) BGC Partners and its Subsidiaries shall indemnify and hold harmless Cantor and the other Cantor Companies for any Indemnifiable Losses arising from or relating thereto, and (ii) without the prior written consent of Cantor, from and after the Effective Time, BGC Partners shall not, and, without Cantor’s prior written consent, shall not permit any of its Subsidiaries to, renew or extend the term of, increase its obligations under, or transfer to a third party, any loan, lease, Contract or other obligation for which Cantor or any other Cantor Company is or may be liable.

SECTION 4.08 Expenses. All legal and other costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such costs and expenses unless expressly otherwise contemplated herein.

SECTION 4.09 New BGC Partners. In order to facilitate Tax-free exchanges of the Holdings Exchangeable Limited Partnership Interests (as defined in the New Holdings Limited Partnership Agreement), Cantor shall have a one-time right, at Holdings’ sole expense, (a) to incorporate, or cause the incorporation of, a newly formed wholly owned Subsidiary of BGC Partners (“New BGC Partners”), (b) to incorporate, or cause the incorporation of, a newly formed wholly owned Subsidiary of New BGC Partners (“New BGC Partners Sub”), and then (c) to cause the merger (the “New BGC Partners Merger”) of New BGC Partners Sub with BGC Partners, with the surviving corporation being a wholly owned Subsidiary of New BGC Partners. In connection with the New BGC Partners Merger, the shares of BGC Partners Class A Common Stock and BGC Partners Class B Common Stock shall each hold equivalent common stock in New BGC Partners, with identical rights to the applicable class of shares held prior to the New BGC Partners Merger. As a condition of the New BGC Partners Merger, (i) BGC Partners shall have received an opinion of counsel, reasonably satisfactory to the Audit Committee of BGC Partners, to the effect that the New BGC Partners Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and (ii) Cantor shall indemnify BGC Partners to the extent that BGC Partners incurs any material income Taxes as a result of the transactions effected pursuant to this Section 4.09.

SECTION 4.10 Commissions and Market Data; Clearing. (a) The Parties agree that (i) Cantor shall have a right to be a customer of BGC Partners and its Subsidiaries and to pay the lowest commission paid by any other customer of BGC Partners or its Affiliates, whether by volume, dollar or other applicable measurement; provided, however, that this right shall terminate upon the earlier of (i) a Change of Control of Cantor and (ii) the last day of the

calendar quarter during which Cantor shall have represented one of the fifteen largest customers of BGC Partners and its Subsidiaries in terms of transaction volume; and (ii) Cantor shall have an unlimited right to internally use market data from BGC Market Data without any cost; provided, however, that Cantor shall have no right to furnish such data to any third party.

(b) From the Closing until the third anniversary of the Closing, (i) Cantor shall cause its applicable Subsidiary or Subsidiaries to provide to BGC Partners or its applicable Subsidiary or Subsidiaries all such services as BGC Partners reasonably determines are reasonably necessary in connection with the clearance, settlement and fulfillment of futures transactions by BGC Partners, and (ii) BGC Partners shall be entitled to receive from Cantor all of the economic benefits and burdens associated with Cantor’s performance of such services; provided, however, that BGC Partners shall use its commercially reasonable efforts to reduce and eliminate its need for such services from Cantor and/or its applicable Subsidiary or Subsidiaries.

SECTION 4.11 Reinvestments in the Opcos; Pre-Emptive Rights. (a) (i) Mandatory Reinvestment by BGC Partners. After the Closing, in the event of any issuance of shares of BGC Partners Common Stock (including any issuance in connection with a merger or other acquisition by BGC Partners, but excluding any issuance of shares of BGC Partners Common Stock upon exchange of Holdings Exchangeable Limited Partnership Interests), BGC Partners shall contribute, directly or indirectly through its Subsidiaries, the net proceeds, if any, received in respect of such issuance to the Opcos in exchange for (A) a U.S. Opco Limited Partnership Interest consisting of a number of U.S. Opco Units equal to (1) the number of additional shares of BGC Partners Common Stock so issued multiplied by (2) the BGC Partners Ratio as of immediately prior to the issuance of such shares of BGC Partners Common Stock and (B) a Global Opco Limited Partnership Interest consisting of a number of Global Opco Units equal to (1) the number of additional shares of BGC Partners Common Stock so issued multiplied by (2) the BGC Partners Ratio as of immediately prior to the issuance of such shares of BGC Partners Common Stock. BGC Partners shall determine the proportion of the net proceeds that shall be paid to U.S. Opco, on the one hand, and Global Opco, on the other hand. Such determination shall be based on BGC Partners’ reasonable judgment as to the proportion of the total fair value, as of the date of issuance of the U.S. Opco Limited Partnership Interest and Global Opco Limited Partnership Interest pursuant to this Section 4.11(a)(i), represented by U.S. Opco or Global Opco, respectively, as of such date.

(ii) Mandatory Reinvestment by Holdings. After the Closing, in the event of any issuances of Holdings Limited Partnership Interests pursuant to the BGC Holdings, L.P. Participation Plan as such plan is amended from time to time, Holdings shall contribute, directly or indirectly through its Subsidiaries, the net proceeds, if any, received in respect of such issuance to the Opcos in exchange for (A) a U.S. Opco Limited Partnership Interest consisting of (1) a number of U.S. Opco Units equal to the number of additional Holdings Units underlying such Holdings Limited Partnership Interests so issued multiplied by (2) the Holdings Ratio as of immediately prior to the issuance of Holdings Limited Partnership Interest and (B) a Global Opco Limited Partnership Interest consisting of a number of Global Opco Units equal to (1) the number of additional Holdings Units underlying such Holdings Limited Partnership Interests so issued multiplied by (2) the Holdings Ratio as of immediately prior to the issuance of

Holdings Limited Partnership Interest. BGC Partners shall determine the proportion of the net proceeds that shall be paid to U.S. Opco, on the one hand, and Global Opco, on the other hand. Such determination shall be based on BGC Partners’ reasonable judgment as to the proportion of the total fair value, as of the date of issuance of the U.S. Opco Limited Partnership Interest and Global Opco Limited Partnership Interest pursuant to this Section 4.11(a)(ii), represented by U.S. Opco or Global Opco, respectively, as of such date.

(iii) Voluntary Reinvestment by BGC Partners. After the Closing, BGC Partners (with the consent of the board of directors of BGC Partners) may elect to have a member of the BGC Partners Group purchase from the Opcos an equal number of U.S. Opco Units and Global Opco Units for a price equal to the Per Unit Price for each set of one U.S. Opco Unit and one Global Opco Unit. Such member of the BGC Partners Group may use cash and/or other assets to make such purchases. In the event that non-cash consideration is used to make such purchases, the value of the aggregate non-cash consideration shall be determined in good faith by the general partner of U.S. Opco and Global Opco, as the case may be, taking into account, if relevant, the acquisition cost thereof. BGC Partners shall determine the proportion of the amount that it receives for such purchase that shall be paid to U.S. Opco, on the one hand, and Global Opco, on the other hand. Such determination shall be based on BGC Partners’ reasonable judgment as to the proportion of the total fair value, as of the date of issuance of the U.S. Opco Limited Partnership Interest and Global Opco Limited Partnership Interest pursuant to this Section 4.11(a)(iii), represented by U.S. Opco or Global Opco, respectively, as of such date.

(b) Pre-Emptive Rights. (i) In the event of any issuance of U.S. Opco Units and Global Opco Units to any member of the BGC Partners Group pursuant to Section 4.11(a)(i) or 4.11(a)(iii) (the member of the BGC Partners Group receiving such U.S. Opco Units and Global Opco Units, the “Receiving Party”), Cantor shall have the right (the “Purchase Right”) to cause any member of the Holdings Group (such Person designated by Cantor, the “Purchase Right Party”) to acquire and be issued, on the terms and subject to the conditions set forth in this Section 4.11(b), an aggregate number of additional U.S. Opco Units and Global Opco Units that would restore the U.S. Opco Group Percentage Interest and Global Opco Group Percentage Interest that the Cantor Group indirectly holds through the Holdings Group to that which it held immediately prior to such issuance to the Receiving Party (assuming for purposes of this calculation that (A) the Purchase Right were exercised and the related sale were closed immediately after the related issuance of the applicable U.S. Opco Units and Global Opco Units to the Receiving Party and (B) the Purchase Right Party shall have been issued any U.S. Opco Units and Global Opco Units for which such Purchase Right Party shall be entitled to receive pursuant to any exercised, but not yet closed, outstanding Election; provided, however, that, if such other Election shall not close in accordance with this Section 4.11(b) prior to the closing of this Purchase Right, the calculation shall be re-calculated excluding such Election) (the “Percentage Adjustment”). In any exercise of a Purchase Right, the Purchase Right Party may elect to acquire less than the aggregate number of additional U.S. Opco Units and Global Opco Units that such Purchase Right Party shall be entitled to purchase pursuant to such Purchase Right (in which case, the Purchase Right with respect to the unexercised portion of the additional U.S. Opco Units and Global Opco Units shall survive and continue in effect on the terms

contemplated by this Section 4.11(b)); provided, however, that, in all cases, the number of U.S. Opco Units so purchased shall equal the number of Global Opco Units so purchased.

(ii) Any U.S. Opco Units and Global Opco Units issued to a Receiving Party or a Purchase Right Party shall be in the form of U.S. Opco Regular Limited Partnership Interests (including the associated U.S. Opco Regular Partnership Units) and Global Opco Regular Limited Partnership Interests (and the associated Global Opco Regular Partnership Units), as the case may be.

(iii) In the event of the approval or authorization of any issuance of U.S. Opco Units and Global Opco Units to the Receiving Party that shall give rise to the Purchase Right in accordance with this Section 4.11(b), the general partners of U.S. Opco and Global Opco shall promptly provide separate written notice thereof (but in any event no later than three (3) Business Days prior to the issuance thereof unless waived by the applicable Purchase Right Party), to Holdings, which notice shall state the number of U.S. Opco Units or Global Opco Units issuable to such Purchase Right Party, the date of issuance and the Per Unit Price payable by the Purchase Right Party (which shall be equal the Per Unit Price paid by the Receiving Party) (the “Notice”).

(iv) In the event that Cantor elects to exercise its Purchase Right (an “Election”), Cantor shall deliver a written notice of exercise to each of U.S. Opco and Global Opco on or prior to ten (10) days after the related issuance of U.S. Opco Regular Partnership Interests and Global Opco Regular Partnership Interests to the Receiving Party, which notice of exercise shall include (A) an irrevocable commitment by the Purchase Right Party to purchase as promptly as practicable an amount of U.S. Opco Units and Global Opco Units equal to the amount specified in the Notice (or, if Cantor shall so elect, an irrevocable commitment to purchase an amount of U.S. Opco Units and Global Opco Units less than that amount specified in the Notice (provided, however, that the number of U.S. Opco Units and Global Opco Units so purchased consist of the same number of units)) at the Per Unit Price specified in the Notice, (B) a statement detailing which Purchase Right Party member(s) will purchase the U.S. Opco Units and Global Opco Units (and, if more than one Purchase Right Party member shall purchase such U.S. Opco Units and Global Opco Units, a statement including the amounts that each such Purchase Right Party member shall purchase) and (C) a guarantee by Holdings of the obligations of the Purchase Right Party to complete the purchase and pay the Purchase Consideration therefor. The irrevocable commitment and the issuance of the additional U.S. Opco Units and Global Opco Units pursuant to the Purchase Right will be conditioned upon the closing of the related issuance of U.S. Opco Units and Global Opco Units to the Receiving Party, the absence of any injunction, order, law, regulation or similar matter that prohibits the consummation of such issuance and the receipt of all regulatory or governmental approvals (including of self regulatory approvals) that shall be required for the applicable Purchase Right Party to acquire the U.S. Opco Units and Global Opco Units; provided, however, that any such purchase shall close no later than 120 days following the Election to exercise its Purchase Right. At the closing of the Purchase Right, (x) the Purchase Right Party shall pay to (1) U.S. Opco an amount in cash and/or other assets equal to the product of the Per Unit Price specified in the Notice and the number of U.S. Opco Units being issued to such Purchase Right Party’s Group

pursuant to the exercise of such Purchase Right and (2) Global Opco an amount in cash and/or other assets equal to the product of the Per Unit Price specified in the Notice and the number of Global Opco Units being issued to such Purchase Right Party’s Group pursuant to the exercise of such Purchase Right (such amount in clauses (1) and (2), the “Purchase Consideration”), and (y) in exchange therefor (1) U.S. Opco shall issue a U.S. Opco Regular Limited Partnership Interest consisting of the applicable number of U.S. Opco Regular Limited Partnership Units and (2) Global Opco shall issue a Global Opco Regular Limited Partnership Interest consisting of the applicable number of Global Opco Regular Limited Partnership Units. In the event that non-cash consideration is used to make such purchases, the value of the aggregate non-cash consideration shall be determined in good faith by the Audit Committee of BGC Partners, taking into account, if relevant, the acquisition cost thereof.

(v) In the event that U.S. Opco or Global Opco, as the case may be, shall: (A) pay a dividend on U.S. Opco Interests or Global Opco Interests, as the case may be, in the form of U.S. Opco Units or Global Opco Units, as the case may be, or make a distribution on U.S. Opco Interests or Global Opco Interests, as the case may be, in the form of U.S. Opco Units or Global Opco Units, as the case may be, (B) subdivide the outstanding U.S. Opco Units or Global Opco Units, as the case may be, into a greater number of U.S. Opco Units or Global Opco Units, as the case may be; (C) combine the outstanding U.S. Opco Units or Global Opco Units, as the case may be, into a smaller number of U.S. Opco Units or Global Opco Units, as the case may be; (D) make a distribution on U.S. Opco Interests or Global Opco Interests, as the case may be, in limited partnership interests other than U.S. Opco Units or Global Opco Units, as the case may be; or (E) issue by reclassification of the outstanding U.S. Opco Units or Global Opco Units, as the case may be, any limited partnership interests, then the U.S. Opco Units or Global Opco Units, as the case may be, issuable pursuant to each outstanding and unexercised Purchase Right immediately prior to such action (including any Purchase Right for which a notice of exercise shall have been delivered but shall not close prior to such action) shall be adjusted so that the applicable Purchase Right Party that thereafter elects to exercise, or closes, such Purchase Right in accordance with this Section shall receive the number of U.S. Opco Units or Global Opco Units, as the case may be, that it would have owned immediately following such action if it had exercised such Purchase Right in full, and been issued the U.S. Opco Units or Global Opco Units, as the case may be, underlying the Purchase Right, immediately prior to such action.

(c) Concurrent Issuance of Holdings Exchangeable Units Upon Reinvestment by the Holdings Group. Concurrently with the issuance of U.S. Opco Units and Global Opco Units to the Purchase Right Party, Cantor or any member of the Cantor Group designated by Cantor shall contribute to Holdings the Purchase Consideration, and in exchange therefor, subject to Section 4.11(e), simultaneously with the issuance of U.S. Opco and Global Opco Units to the Purchase Right Party pursuant to Section 4.11(b), Holdings shall issue to Cantor or the designated member of the Cantor Group, a Holdings Exchangeable Limited Partnership Interest consisting of a number of Holdings Exchangeable Units equal to the number of U.S. Opco Units issued to the Purchase Right Party.

(d) Parity Between U.S. Opco Units and Global Opco Units; Intention for Ratios To Equal One. To the extent that any U.S. Opco Units or Global Opco Units are issued pursuant to this Section 4.11, an equal number of Global Opco Units or U.S. Opco Units, respectively, shall be issued. It is the non-binding intention of the Parties that the BGC Partners Ratio and the Holdings Ratio shall in each case equal one (1). In furtherance of the foregoing, (i) in the event of any issuance of U.S. Opco Units and Global Opco Units to any member of the BGC Partners Group pursuant to Section 4.11(a)(iii), immediately following such an issuance, BGC Partners shall declare a pro rata stock dividend so that the number of issued and outstanding shares of BGC Partners Common Stock shall be increased by a number equal to (x) the additional U.S. Opco Units issued to the BGC Partners Group pursuant to Section 4.11(a)(iii), multiplied by (y) the BGC Partners Ratio as of immediately prior to the issuance of such U.S. Opco Units; and (ii) in the event of any issuance of U.S. Opco Units and Global Opco Units to any member of the Holdings Group pursuant to Section 4.11(b), immediately following such an issuance, Holdings shall declare a pro rata dividend so that the number of issued and outstanding Holdings Units shall be increased by a number equal to (x) the additional U.S. Opco Units issued to the Holdings Group pursuant to Section 4.11(b), multiplied by (y) the Holdings Ratio as of immediately prior to the issuance of such U.S. Opco Units; provided, however, that, in each of cases (a) and (b), no fractional share of BGC Partners Common Stock or fractional Holdings Unit shall be issued and, in lieu thereof, BGC Partners and Holdings, as the case may be, shall be entitled to pay cash to the Person who otherwise would have received such fractional share of BGC Partners Common Stock or fractional Holdings Unit based on the market price of BGC Partners Common Stock as determined by BGC Partners or Holdings, as the case may be.

(e) No Fractional Units or Common Stock. Notwithstanding anything to the contrary herein, U.S. Opco, Global Opco, Holdings and BGC Partners shall not transfer or issue any fractional U.S. Opco Units, Global Opco Units, Holdings Units or BGC Partners Common Stock, as the case may be. In lieu thereof, upon any issuance of additional U.S. Opco Units, Global Opco Units, Holdings Units or BGC Partners Common Stock pursuant to this Section 4.11, the applicable Person shall transfer U.S. Opco Units, Global Opco Units, Holdings Units or BGC Partners Common Stock, as the case may be, rounded to the nearest whole unit or share.

SECTION 4.12 Distributions to Holders of BGC Partners Common Stock. It is the non-binding intention of BGC Partners to match the distribution policy of Holdings, so that BGC Partners uses a substantial portion of the cash that it receives from the Opcos to distribute as dividends to the holders of BGC Partners Common Stock; provided, however, that nothing in this Section shall prohibit BGC Partners from reinvesting in the Opcos pursuant to Section 4.11(a) or shall require Cantor to exercise its Purchase Right pursuant to Section 4.11(b).

SECTION 4.13 Intellectual Property License. Cantor for itself and on behalf of those of its Subsidiaries that own any right, title or interest in those Intellectual Property assets which are currently used or currently contemplated to be used in the conduct of the business of BGC Partners or its Subsidiaries hereby grants to BGC Partners and/or one or more of its Subsidiaries a non-exclusive, perpetual, irrevocable, worldwide, non-transferable (except as described below) and royalty-free license (the “License”) to all such Intellectual Property in connection with the operation of the business of BGC Partners and its Subsidiaries on and after the Closing Date. Notwithstanding the foregoing, the License shall not constitute an assignment or transfer of any Intellectual Property owned by a third party if both (a) such assignment or

transfer would be ineffective or would constitute a default under, or other contravention of, the provisions of a Contract without the approval or consent of a third party, and (b) such approval or consent is not obtained; provided, however, that Cantor agrees to use its commercially reasonable efforts to obtain any such approval or consent (it being understood that such efforts shall not require Cantor to pay to the third party any compensation or other remuneration to obtain such approval or consent). The License shall not be transferable except to any purchaser of (a) all or substantially all of the business or assets of BGC Partners and its Subsidiaries; or (b) a business, division or subsidiary of BGC Partners or its Subsidiaries pursuant to a bona fide acquisition of a line of business of BGC Partners and its Subsidiaries.

Written notice to such indemnifying party of the existence of such claim shall be given by the Indemnitee as soon as practicable after the Indemnitee first receives notice of the potential claim; provided, however, that any failure to provide such prompt notice of the event giving rise to such claim to the indemnifying party shall not affect the Indemnitee’s right to indemnification or relieve the indemnifying party of its obligations under this Article V except to the extent that such failure results in a lack of actual notice of the event giving rise to such claim and such indemnifying party actually incurs an incremental expense or otherwise has been materially prejudiced as a result of such delay.

Any such notice shall describe the Third-Party Claim in reasonable detail, including, if known, the amount of the Indemnifiable Loss for which indemnification may be available or a good faith estimate thereof.

(b) An indemnifying party may elect (but is not required) to assume the defense of and defend, at such indemnifying party’s own expense and by such indemnifying party’s own counsel, any Third-Party Claim. Within 30 days after the receipt of notice from an Indemnitee in accordance with Section 5.07(a), the indemnifying party shall notify the Indemnitee of its election whether the indemnifying party will assume responsibility for defending such Third-Party Claim, which election shall specify any reservations or exceptions. After notice from an indemnifying party to an Indemnitee of its election to assume the defense of a Third-Party Claim, such Indemnitee shall have the right to participate in the defense, compromise, or settlement thereof, but, as long as the indemnifying party pursues such defense, compromise or settlement with reasonable diligence, the fees and expenses of such Indemnitee incurred in participating in such defense shall be paid by the Indemnitee. Notwithstanding the foregoing, the Indemnitee shall be entitled to engage one separate counsel of its own choosing to participate in such defense, compromise or settlement.

(c) If an indemnifying party elects not to assume responsibility for defending a Third-Party Claim, or fails to notify an Indemnitee of its election as provided in Section 5.07(b), such Indemnitee may defend such Third-Party Claim at the cost and expense of the indemnifying party; provided, however, that the indemnifying party may thereafter assume the defense of and defend such Third-Party Claim upon notice to the Indemnitee (but the cost and expense of such Indemnitee in defending such Third-Party Claim incurred from the last day of the notice period under Section 5.07(b) until such date as the indemnifying party shall assume the defense of such Third-Party Claim shall be paid by the indemnifying party).

(d) If an indemnifying party elects not to assume responsibility for defending a Third-Party Claim, or fails to notify an Indemnitee of its election as provided in Section 5.07(b), and has not thereafter assumed such defense as provided in Section 5.07(c), such Indemnitee shall have the right to settle or compromise such Third-Party Claim, and any such settlement or compromise made or caused to be made of such Third-Party Claim in accordance with this Article V shall be binding on the indemnifying party, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise. Notwithstanding the foregoing sentence, the Indemnitee shall not compromise or settle a Third-Party Claim without the express prior consent of the indemnifying party (not to be unreasonably withheld or delayed); provided, however, that such prior consent shall not be required in the case of any such compromise or settlement if and only if the compromise or settlement includes, as part thereof, a full and unconditional release by the plaintiff or claimant of the Indemnitee and the indemnifying party from all Liability with respect to such Third-Party Claim and does not require the indemnifying party to be subject to any non-monetary remedy.

Party Claim in accordance with this Article V shall be binding on the Indemnitee, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise. Notwithstanding the foregoing sentence, the indemnifying party shall not have the right to admit Liability on behalf of the Indemnitee and shall not compromise or settle a Third-Party Claim in each case without the express prior consent of the Indemnitee (not to be unreasonably withheld or delayed); provided, however, that such prior consent shall not be required in the case of any such compromise or settlement if and only if the compromise or settlement includes, as a part thereof, a full and unconditional release by the plaintiff or claimant of the Indemnitee from all Liability with respect to such Third-Party Claim and does not require the Indemnitee to make any payment that is not fully indemnified under this Agreement or to be subject to any non-monetary remedy.

SECTION 5.08 Mitigation. Each Indemnitee claiming a right to indemnification shall make commercially reasonable efforts to mitigate any claim or liability that such Indemnitee asserts under this Article V.

Any Special Allocation Losses to the extent relating to, arising out of or resulting from the Actions set forth on Schedule 5.09 shall be allocated to Holdings pursuant to terms of the New U.S. Opco Limited Partnership Agreement and the New Global Opco Limited Partnership Agreement and allocated to the capital accounts of the Limited Partnership Interests of BGC Holdings held by the Cantor Group, the Founding Partners and the Working Partners (each as defined in the New Holdings Limited Partnership Agreement) pursuant to the terms of the New Holdings Limited Partnership Agreement. Any such Action set forth on Schedule 5.09 shall be subject to Section 5.07 as if such Action were a Third-Party Claim.

SECTION 5.10 Exclusive Remedies. Notwithstanding any other provision contained in this Agreement, except in the case of a fraud or willful misconduct on the part of a Party hereto and except as specifically set forth in this Article V, there shall be no rights, claims or remedies (whether in Law or in equity) available to any Indemnitee for breaches by any indemnifying party of representations, warranties, covenants or other agreements under this Agreement or otherwise relating to this Agreement or the transactions contemplated hereby; provided, however, that the Parties hereto shall each have and retain all rights and remedies to bring actions for specific performance and/or injunctive relief existing in their favor under this Agreement, at Law or equity, to enforce or prevent a breach or violation of any provision of this Agreement.

SECTION 5.11 Merger Agreement Indemnification. Nothing contained in this Article V shall in any way derogate from Cantor’s obligation to provide indemnification on the terms and subject to the conditions set forth in the Merger Agreement.

(b) Each of the Parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, any Delaware State court and the Federal court of the United States of America sitting in the State of Delaware) for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby (and agrees that no such action, suit or proceeding relating to this Agreement shall be brought by it or any of its subsidiaries except in such courts). Each of the Parties further agrees that, to the fullest extent permitted by Applicable Law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the Parties hereto irrevocably and unconditionally waives (and agrees not to plead or claim), any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 8.03 Amendment and Modification. This Agreement may be amended, modified or supplemented only by a written agreement signed by all of the Parties; provided, however, that any such amendment, modification or supplement shall require the prior written approval of the Special Committee of the Board of Directors of eSpeed, if prior to the effective time of the Merger, or the Audit Committee of the Board of Directors of the Surviving Company, if after the effective time of the Merger.

SECTION 8.04 Successors and Assigns; No Third-Party Beneficiaries. (a) This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties and their successors and permitted assigns, but neither this Agreement nor any rights, interests and obligations hereunder shall be assigned by any Party without the prior written consent of each of the other Parties (which consent shall not be unreasonably withheld); provided, however, that BGC Partners may assign its rights and obligations to a wholly owned subsidiary of BGC Partners without the prior written consent of the other Party; provided, further, that no such assignment shall relieve BGC Partners of any of its obligations hereunder.

(b) This Agreement is solely for the benefit of the Parties and is not intended to confer upon any other Persons any rights or remedies hereunder, except that prior to the effective time of the Merger, eSpeed shall be a third-party beneficiary of this Agreement and shall be entitled to enforce the rights of BGC Partners under this Agreement.
