SECTION 5.04. Allocations and Tax Matters. (a) Book Allocations. After giving effect to the allocations set forth in Section 2 of Exhibit D hereto and Section 6.01(d), for purposes of computing Capital Accounts and allocating any items of income, gain, loss or deduction thereto, with respect to each Accounting Period, all items of income, gain, loss or

-34-

deduction of the Partnership shall be allocated among the Capital Accounts of the Partners in proportion to their Percentage Interest as of the end of such Accounting Period; provided that any and all items of income, gain, loss or deduction to the extent resulting from a Special Item will be allocated entirely to the Capital Accounts of the Limited Partnership Interests (other than the Special Voting Limited Partnership Interest), pro rata in proportion to the number of Units underlying such Interests or in other proportion as determined by a Majority in Interest (it being the intention that, in all cases, BGC Partners, as the holder of the Special Voting Limited Partner Interest or otherwise, shall not bear the benefits and burdens of the Special Item). For purposes of the foregoing, except as may be otherwise agreed by the General Partner and the holders of a Majority in Interest, items of income, gain, loss and deductions of the Partnership allocable to the Partners shall be calculated in the same manner in which such items are calculated for federal income tax purposes with the following adjustments: (i) items of gain, loss and deduction shall be computed based on the Book Values of the Partnership’s assets rather than upon the assets’ adjusted bases for federal income tax purposes; (ii) the amount of any adjustment to the Book Value of any assets of the Partnership pursuant to Section 743 of the Code shall not be taken into account; (iii) any tax exempt income received by the Partnership shall be taken into account as an item of income; and (iv) any expenditure of the Partnership described in Section 705(a)(2)(B) of the Code and any expenditure considered to be an expenditure described in Section 705(a)(2)(B) of the Code pursuant to Treasury Regulations under Section 704(b) of the Code shall be treated as a deductible expense. The General Partner may, with the consent of a Majority in Interest, make such other adjustments to the calculation of items of income, gain, loss and deduction as it deems appropriate to more properly reflect the income or loss of the Partnership.

(b) Tax Allocations. Except as otherwise required under Section 704(c) of the Code and the Treasury Regulations promulgated thereunder, the Partnership shall cause each item of income, gain, loss or deduction recognized by the Partnership to be allocated among the Partners for U.S. federal, state and local income and, where relevant, non-U.S. tax purposes in the same manner that each such item is allocated to the Partners’ Capital Accounts or as otherwise provided herein. Allocations required by Section 704(c) of the Code shall be made using the “traditional method” described in Treasury Regulation section 1.704-3(b).

SECTION 5.05. General Partner Determinations. All determinations, valuations and other matters of judgment required to be made for purposes of this Article V, including with respect to allocations to Capital Accounts and accounting procedures and tax matters not expressly provided for by the terms of this Agreement, or for determining the value of any type or form of proceeds, contribution or distributions hereunder shall be made by the General Partner in good faith. In the event that an additional Partner is admitted to the Partnership and contributes property to the Partnership, or an existing Partner contributes additional property to the Partnership, pursuant to this Agreement, the value of such contributed property shall be the fair market value (or book value, if so agreed by the applicable Partner and the General Partner) of such property as reasonably determined by the General Partner.

SECTION 5.06. Books and Accounts. (a) The Partnership shall at all times keep or cause to be kept true and complete records and books of account, which records and books shall be maintained in accordance with U.S. generally accepted accounting principles.

-35-

Such records and books of account shall be kept at the principal place of business of the Partnership by the General Partner. The Limited Partners shall have the right to gain access to all such records and books of account (including schedules thereto) for inspection and view (at such reasonable times as the General Partner shall determine) for any purpose reasonably related to their Interests. The Partnership’s accounts shall be maintained in U.S. dollars.

(b) The Partnership’s fiscal year shall begin on the first day of January and end on the thirty-first day of December of each year, or shall be such other period designated by the General Partner. At the end of each fiscal year, the Partnership’s accounts shall be prepared, presented to the General Partner and submitted to the Partnership’s auditors for examination.

(c) The Partnership’s auditors shall be an independent accounting firm of international reputation to be appointed from time to time by the General Partner. The Partnership’s auditors shall be entitled to receive promptly such information, accounts and explanations from the General Partner and each Partner that they deem reasonably necessary to carry out their duties. The Partners shall provide such financial, tax and other information to the Partnership as may be reasonably necessary and appropriate to carry out the purposes of the Partnership.

SECTION 5.07. Tax Matters Partner. The General Partner is hereby designated as the tax matters partner of the Partnership, in accordance with the Treasury Regulations promulgated pursuant to Section 6231 of the Code and any similar provisions under any other state or local or non-U.S. tax laws. The General Partner shall have the authority, in its sole and absolute discretion, to (a) make an election under Section 754 of the Code on behalf of the Partnership, and each Partner agrees to provide such information and documentation as the General Partner may reasonably request in connection with any such election, (b) determine the manner in which “excess nonrecourse liabilities” (within the meaning of Treasury Regulation section 1.752-3(a)(3)) are allocated among the Partners and (c) make any other election or determination with respect to taxes (including with respect to depreciation, amortization and accounting methods).

SECTION 5.08. Tax Information. The Partnership shall use commercially reasonable efforts to prepare and mail as soon as reasonably practicable after the end of each taxable year of the Partnership, to each Partner (and each other Person that was such a Partner during such taxable year or its legal representatives), U.S. Internal Revenue Service Schedule K-1, “Partner’s Share of Income, Credits, Deductions, Etc.,” or any successor schedule or form, for such Person.

SECTION 5.09. Withholding. Notwithstanding anything herein to the contrary, the Partnership is authorized to withhold from distributions and allocations to the Partners, and to pay over to any federal, state, local or foreign governmental authority any amounts believed in good faith to be required to be so withheld pursuant to the Code or any provision of any other federal, state, local or foreign law and, for all purposes under this Agreement, shall treat such amounts (together with any amounts that are withheld from payments to the Partnership or any of its Subsidiaries attributable to a direct or indirect Partner of the Partnership) as distributed to those Partners with respect to which such amounts were withheld. If the Partnership is obligated

-36-

to pay any amount to a taxing authority on behalf of (or in respect of an obligation of) a Partner (including, federal, state and local or other withholding taxes), then such Partner shall indemnify the Partnership in full for the entire amount of any Tax (but not any interest, penalties and expenses associated with such payment). If the Partnership elects to withhold or make any payment to any federal, state, local or foreign governmental authority in respect of a payment that otherwise would be made to any Founding/Working Partner or REU Partner, such Founding/Working Partner or REU Partner shall cooperate with the General Partner by providing such information or forms as are reasonably requested by the General Partner in connection with such withholding or the making of such payments. Each Founding/Working Partner or REU Partner who is an employee of the Partnership, the Opcos, their Subsidiaries or of an Affiliated Entity (or whose stock or other beneficial interest is owned by such an employee) authorizes the Partnership to withhold additional amounts for payment on behalf of such Founding/Working Partner or REU Partner of federal, state and local income tax from the compensation paid to such Founding/Working Partner or REU Partner (or owner of stock or other beneficial interest of a corporate or other entity Founding/Working Partner or REU Partner).

ARTICLE VI

DISTRIBUTIONS

SECTION 6.01. Distributions in Respect of Partnership Interests. (a) Subject to the remaining sentence of this Section 6.01(a), the Partnership shall distribute to each Partner from such Partner’s Capital Account (i) on or prior to each Estimated Tax Due Date such (y) Partner’s Estimated Proportionate Quarterly Tax Distribution for such fiscal quarter, plus (z) with respect to Partners who are members of the Cantor Group, the Founding/Working Partners and the REU Limited Partners, an amount (positive or negative) calculated using the methodology contemplated by the definition “Estimated Proportionate Quarterly Tax Distribution” (taking into account for this purpose items of income, gain, loss or deduction allocated in respect of any Special Item and disregarding all other items) for such fiscal quarter in respect of any items of income, gain, loss or deduction allocated in respect of any Special Item, and (ii) as promptly as practicable after the end of each fiscal quarter of the Partnership (but otherwise on such date and time as determined by the General Partner) an amount equal to all amounts allocated to such Partner’s Capital Account with respect to such quarter (reduced by the amount of any prior distributions pursuant to this Section 6.01(a)), with such distribution to occur on such date and time as determined by the General Partner; provided that distributions pursuant to this clause (ii) shall be made to a Partner only to the extent of the positive balance in such Partner’s Capital Account unless otherwise determined by the General Partner; provided, however, that in each case appropriate adjustments shall be made to reflect any amounts treated as distributed pursuant to Section 5.09; provided, further, however, that with the prior written consent of the holders of a Majority in Interest, the Partnership may decrease the amount distributed from such Partners’ Capital Accounts; provided, further, that the Partnership shall not be obligated to make distributions in excess of its cash available for such distributions. Notwithstanding anything to the contrary set forth in this Section 6.01, if the Partnership is unable to make the distributions contemplated by the foregoing as a result of any Special Item, then the Partnership shall use reasonable best efforts to borrow such amounts as are necessary to make distributions that would have been received by the BGC Partners Group in the absence of any such Special Item and to make the Estimated Proportionate Quarterly Tax Distributions to

-37-

the Cantor Group and to Founding/Working Partners, and the costs of any such costs borrowing shall be treated as a Special Item. No distributions shall be made by the Partnership except as expressly contemplated by Sections 6.01 and 9.03(a) and Article XII.

(b) In accordance with Article XI, the General Partner may determine to withhold from distributions pursuant to this Section 6.01 amounts reflecting an Extraordinary Income Item or an Extraordinary Expenditure with respect to Founding/Working Partner Interests or REU Interests.

(c) The General Partner, with the consent of a Majority in Interest, may direct the Partnership to distribute all or part of any amount that is otherwise distributable to a Founding/Working Partner or an REU Partner, as the case may be, under this Section 6.01 in the form of a distribution of Publicly Traded Shares, valued at the average of the closing prices of such shares, as reported by the national securities exchange or quotation system upon which such shares are then listed or quoted, during the 10-trading-day period immediately preceding the distribution (or such other fair and reasonable pricing method as may be selected by the General Partner), or in other property valued at its then-fair market value, as determined by the General Partner in its sole and absolute discretion. The distribution of Publicly Traded Shares or other property to a Partner pursuant to this Section 6.01(c) shall result in a reduction in such Partner’s Capital Account and Adjusted Capital Account by an amount equal to the value of such distributed shares or property determined as provided in this Section 6.01(c). Any gain recognized or deemed recognized as a result of such distribution shall not affect any Adjusted Capital Account unless otherwise deemed appropriate by mutual agreement of the General Partner and a Majority in Interest, in their sole and absolute discretion.

(d) The General Partner, with the consent of a Majority in Interest, in its sole and absolute discretion, may direct the Partnership, upon a Founding/Working Partner’s or REU Partner’s death, retirement, withdrawal from the Partnership or other full or partial redemption of Units, to distribute to such Partner (or to his or her Personal Representative, as the case may be) a number of Publicly Traded Shares or an amount of other property that the General Partner determines is appropriate in light of the goodwill associated with such Partner and his, her or its Units, such Partner’s length of service, responsibilities and contributions to the Partnership and/or other factors deemed to be relevant by the General Partner. Notwithstanding Sections 5.01 and 5.04, the distribution of Publicly Traded Shares or other property to a Founding/Working Partner or REU Partner, as the case may be, pursuant to this Section 6.01(d) shall result in a net reduction in such Partner’s Capital Account and Adjusted Capital Account, unless otherwise determined by the General Partner in its sole and absolute discretion. To the extent necessary or appropriate to give effect to the intent of this provision, as determined by the General Partner in its sole and absolute discretion, the Partnership shall make a special allocation to the distributee Founding/Working Partner or REU Partner, as the case may be, of gain, if any, that arises on any such distribution of the Publicly Traded Shares or other property.

(e) Notwithstanding any other provision of this Agreement, no amount shall be distributed to any Founding/Working Partner or REU Partner in respect of income or gain allocable to such Founding/Working Partner or REU Partner pursuant to Section 2

-38-

of Exhibit D to this Agreement except to the extent the General Partner determines in its sole and absolute discretion that such a distribution is consistent with the intent of this Agreement.

SECTION 6.02. Limitation on Distributions. Notwithstanding any provision to the contrary contained in this Agreement, the Partnership and the General Partner, on behalf of the Partnership, shall not be required to make a distribution to a Partner on account of its interest in the Partnership if such distribution would violate the Act or any other applicable law.

ARTICLE VII

TRANSFERS OF INTERESTS

SECTION 7.01. Transfers Generally Prohibited. No Partner may Transfer or agree or otherwise commit to Transfer all or any portion of, or any of rights, title and interest in and to, its Interest, except as permitted by the terms and conditions set forth in this Article VII (and, with respect to the Founding/Working Partners and the REU Partners only, Article XII). The Schedules shall be revised pursuant to Section 1.03 from time to time to reflect any change in the Partners or Interests to reflect any Transfer permitted by this Article VII.

SECTION 7.02. Permitted Transfers. (a) Regular Limited Partnership Interests. No Regular Limited Partner (other than the Special Voting Limited Partner, which shall be governed by Section 7.02(b)) may Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its Regular Limited Partnership Interest (other than the Special Voting Limited Partnership Interest, which shall be governed by Section 7.02(b)), except any such Transfer (i) pursuant to Section 4.03(b)(i) in connection with the Contribution and the Separation or Section 4.03(b)(iv) or 8.01, (ii) if such Regular Limited Partner shall be a member of the Cantor Group, to any Person; or (iii) for which the General Partner and the Exchangeable Limited Partners (with such consent to require the affirmative vote of a Majority in Interest) shall have provided their respective prior written consent (which consent shall not be unreasonably withheld or delayed). With respect to any Exchangeable Limited Partnership Interest Transferred by a Cantor Company to another Person, Cantor may elect, prior to or at the time of such Transfer, either (1) that such Person shall receive such Interest in the form of an Exchangeable Limited Partnership Interest and that such Person shall thereafter be an Exchangeable Limited Partner for purposes of this Agreement so long as such Person continues to hold such Interest or (2) that such Person shall receive such Interest in the form of a Regular Limited Partnership Interest (other than an Exchangeable Limited Partnership Interest or a Special Voting Limited Partnership Interest), and that such Person shall not be an Exchangeable Limited Partner for purposes of this Agreement as a result of holding such Interest. For the avoidance of doubt, if Cantor shall not so elect, such Transferred Interest shall not be designated as an Exchangeable Limited Partnership Interest.

(b) Special Voting Limited Partnership Interest. The Special Voting Limited Partner may not Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its Special Voting Limited Partnership Interest, except any such Transfer (i) to a wholly owned Subsidiary of BGC Partners; provided that, in the event that such transferee shall cease to be a wholly owned Subsidiary

-39-

of BGC Partners, the Special Voting Limited Partnership Interest shall automatically be Transferred to BGC Partners, without the requirement of any further action on the part of the Partnership, BGC Partners or any other Person; or (ii) pursuant to Section 4.03(b)(i) in connection with the Contribution and the Separation. Upon removal of any Special Voting Limited Partner, notwithstanding anything herein to the contrary, the Special Voting Limited Partnership Interest shall be transferred to the Person being admitted as the new Special Voting Limited Partner, simultaneously with admission and without the requirement of any action on the part of the Special Voting Limited Partner being removed or any other Person.

(c) Founding Partner Interest. No Founding Partner may Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its Founding Partner Interest, except any such Transfer (i) pursuant to a redemption as set forth in Section 12.03; (ii) pursuant to Section 4.03(c)(i) in connection with the Contribution and the Separation or Section 4.03(c)(iii) or 8.01; (iii) to any Cantor Company; provided that in the event that such transferee shall cease to be a Cantor Company, such Founding Partner Interest shall automatically Transfer to Cantor; (iv) with the consent of a Majority in Interest, to any other Founding Partner; or (v) with the mutual consent of the General Partner and a Majority in Interest (which consent may be withheld for any reason or for no reason whatsoever), to any other Person.

(d) Working Partner Interest. No Working Partner may Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its Working Partner Interest, except any such Transfer (i) pursuant to a redemption as set forth in Section 12.03; (ii) pursuant to Section 4.03(d)(iii) or 8.01; (iii) to any Cantor Company; provided that in the event that such transferee shall cease to be a Cantor Company, such Working Partner Interest shall automatically Transfer to Cantor; or (iv) with the mutual consent of the General Partner and a Majority in Interest (which consent may be withheld for any reason or for no reason whatsoever), to any other Person.

(e) General Partnership Interest. The General Partner may not Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its General Partnership Interest, except any such Transfer (i) to a new General Partner in accordance with this Section, (ii) with the prior written consent (not to be unreasonably withheld or delayed) of the Special Voting Limited Partner, to any other Person, or (iii) pursuant to Section 4.03(a)(i) in connection with the Contribution and the Separation. Any General Partner may be removed at any time, with or without cause, by the Special Voting Limited Partner in its sole and absolute discretion, and the General Partner may resign from the Partnership for any reason or for no reason whatsoever; provided, however, that, as a condition to any such removal or resignation, (A) the Special Voting Limited Partner shall first appoint another Person as the new General Partner; (B) such Person shall be admitted to the Partnership as the new General Partner (upon the execution and delivery of an agreement to be bound by the terms of this Agreement and such other agreements, documents or instruments requested by the resigning General Partner); and (C) such resigning or removed General Partner shall Transfer its entire General Partnership Interest to the new General Partner. The admission of the new General Partner shall be deemed effective immediately prior to the effectiveness of the resignation

-40-

of the resigning General Partner, and shall otherwise have the effects set forth in Section 4.03(a)(iii). Upon removal of any General Partner, notwithstanding anything herein to the contrary, the General Partnership Interest shall be transferred to the Person being admitted as the new General Partner, simultaneously with admission and without the requirement of any action on the part of the General Partner being removed or any other Person.

(f) REU Interest. No REU Partner may Transfer or agree or otherwise commit to Transfer all or any portion of, or any right, title and interest in and to, its REU Interest, except any such Transfer (i) pursuant to a redemption as set forth in Section 12.03; (ii) pursuant to Section 4.03(e)(i) concurrently with the Merger or Section 4.03(e)(iii) or 8.01; (iii) to any Cantor Company; provided that in the event that such transferee shall cease to be a Cantor Company, such REU Interest shall automatically Transfer to Cantor; or (iv) with the mutual consent of the General Partner and a Majority in Interest (which consent may be withheld for any reason or for no reason whatsoever), to any other Person.

SECTION 7.03. Admission as a Partner Upon Transfer. Notwithstanding anything to the contrary set forth herein, a Transferee who has otherwise satisfied the requirements of Section 7.02 shall become a Partner, and shall be listed as a “Regular Limited Partner,” “Exchangeable Limited Partner,” “Special Voting Limited Partner,” “Founding Partner,” “REU Partner,” “Working Partner” or “General Partner” as applicable, on Schedule 4.01, and shall be deemed to receive the Interest being Transferred, in each case only at such time as such Transferee executes and delivers to the Partnership an agreement in which the Transferee agrees to be admitted as a Partner and bound by this Agreement and any other agreements, documents or instruments specified by the General Partner and such agreements (when applicable) shall have been duly executed by the General Partner; provided, however, that if such Transferee (a) is at the time of such Transfer a Partner of the applicable class of Interests being Transferred, (b) receives Interests in the Cantor Redemption or (c) has previously entered into an agreement pursuant to which the Transferee shall have agreed to become a Partner and be bound by this Agreement (which agreement is in effect at the time of such Transfer), such Transferee shall not be required to enter into any such agreements unless otherwise determined by the General Partner; provided, further, that the Transfers, admissions to and withdrawals from the Partnership as Partners, contemplated by Sections 4.03(a)(i), 4.03(b)(i) or 4.03(c)(i) shall not require the execution or delivery of any further agreements or other documentation hereunder.

SECTION 7.04. Transfer of Units and Capital with the Transfer of an Interest. Notwithstanding anything herein to the contrary, each Partner who Transfers an Interest shall be deemed to have Transferred the entire Interest, including the associated Units and Capital of such Interest, or, if a portion of an Interest is being Transferred, each Partner who Transfers a portion of an Interest shall specify the number of Units being so Transferred and such Transfer shall include a proportionate amount of Capital of such Interest, to the Transferee.

SECTION 7.05. Encumbrances. No Partner may charge or encumber its Interest or otherwise subject its Interest to a lien, pledge, security interest, right of first refusal, option or other similar limitation (an “Encumbrance”), except in each case for those created by this Agreement; provided, however, that, notwithstanding anything herein to the contrary, an Exchangeable Limited Partner may Encumber its Exchangeable Limited Partnership Interest in connection with any bona fide bank financing transaction.

-41-

SECTION 7.06. Legend. Each Partner agrees that any certificate issued to it to evidence its Interests shall have inscribed conspicuously on its front or back the following legend:

THE PARTNERSHIP INTEREST IN BGC HOLDINGS, L.P. REPRESENTED BY THIS CERTIFICATE (INCLUDING ASSOCIATED UNITS AND CAPITAL) HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR REGISTERED OR QUALIFIED UNDER THE SECURITIES LAWS OF ANY STATE OR FOREIGN JURISDICTION, AND THIS PARTNERSHIP INTEREST MAY NOT BE TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED, ENCUMBERED OR OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, EXCEPT (A) EITHER (1) WHILE A REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE REGISTRATIONS AND QUALIFICATIONS ARE IN EFFECT OR (2) PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT (INCLUDING, IF APPLICABLE, REGULATION S THEREUNDER) AND SUCH OTHER APPLICABLE LAWS AND (B) IF PERMITTED BY THE LIMITED PARTNERSHIP AGREEMENT OF BGC HOLDINGS, L.P., AS IT MAY BE AMENDED FROM TIME TO TIME, WHICH CONTAINS STRICT PROHIBITIONS ON TRANSFERS, SALES, ASSIGNMENTS, PLEDGES, HYPOTHECATIONS, ENCUMBRANCES OR OTHER DISPOSITIONS OF THIS PARTNERSHIP INTEREST OR ANY INTEREST THEREIN (INCLUDING ASSOCIATED UNITS AND CAPITAL).

SECTION 7.07. Effect of Transfer Not in Compliance with this Article. Any purported Transfer of all or any part of a Partner’s Interest, or any interest therein, that is not in compliance with this Article VII (and, in the case of the Founding/Working Partner Interests or REU Interests, Article XII) shall, to the fullest extent permitted by law, be void ab initio and shall be of no effect.

ARTICLE VIII

EXCHANGE RIGHTS

SECTION 8.01. Exchange Rights. (a) An Exchange Right Interest shall be exchangeable, at the option of such Limited Partner holding such Interest, with BGC Partners for BGC Partners Common Stock, on the terms, and subject to the conditions, set forth in this Article VIII.

(b) (i) An Exchangeable Limited Partner shall be entitled to exchange all or a portion of its Exchangeable Limited Partnership Interest; provided that, in the case of the Exchangeable Limited Partnership Interest issued on the date of this Agreement or prior to the first anniversary of the Closing Date (as defined in the Separation Agreement), such Exchangeable Limited Partnership Interest may be exchanged hereunder only on or after the first anniversary of the Closing Date (as defined in the Separation Agreement) or for

-42-

exchanges that occur prior to the Merger or pursuant to the next sentence. Notwithstanding the foregoing or anything else to the contrary in this Agreement, prior to the first anniversary of the Closing Date (as defined in the Separation Agreement), Cantor or any Cantor Company shall be entitled to exchange from time to time a portion of its Exchangeable Limited Partnership Interests for up to an aggregate of 20 million shares of BGC Partners Class A Common Stock; provided that any such exchange shall be conditioned upon the consummation of a broad-based public offering including all shares of BGC Partners Class A Common Stock received upon such exchange, where such offering is underwritten by a nationally recognized investment banking firm.

(ii) A Founding Partner shall not be entitled to exchange any portion of its Founding Partner Interest; provided, however, that the Exchangeable Limited Partners (by affirmative vote of a Majority in Interest) may, in their sole discretion, cause all or a portion of the outstanding Founding Partner Units to be exchangeable (including mandatorily exchangeable) with BGC Partners for shares of BGC Partners Class A Common Stock pursuant to Section 8.01(c)(ii); provided, however, that BGC Partners shall not be required to effectuate such an exchange if such Founding Partner Interest shall be subject to any Encumbrance; provided, further, that in the case of any exchange of High Distribution II Units or High Distribution III Units by a Founding Partner, BGC Partners shall not be required to effectuate such exchange unless and until such Partner shall have paid in full any then outstanding CFLP HDII Account or CFLP HDIII Account with respect to such Units. The terms and conditions on which such Founding Partner Units shall become exchangeable (including the circumstances in which such Founding Partner Units shall be mandatorily exchangeable and/or cease to be exchangeable) shall be determined by the Exchangeable Limited Partners (by affirmative vote of a Majority in Interest). Notwithstanding the foregoing, Cantor shall not be able to make a Founding Partner Interest exchangeable if the terms and conditions of such exchange would in any way diminish or adversely affect the rights of BGC Partners or its Subsidiaries (it being understood that an obligation by BGC Partners to deliver shares of BGC Partners Class A Common Stock upon exchange shall not be deemed to diminish or adversely affect the rights of BGC Partners or its Subsidiaries).

(iii) An REU Partner shall not be entitled to exchange any portion of its REU Interest; provided, however, that BGC Partners may, with the written consent of a Majority in Interest, cause all or a portion of the outstanding REUs to be exchangeable (including mandatorily exchangeable) with BGC Partners for shares of BGC Partners Class A Common Stock pursuant to Section 8.01(c)(iii); provided, however, that BGC Partners shall not be required to effectuate such an exchange if such REU Interest shall be subject to any Encumbrance. The terms and conditions on which such REUs shall become exchangeable (including the circumstances in which such REUs shall cease to be mandatorily exchangeable and/or exchangeable) shall be determined by BGC Partners, with the written consent of a Majority in Interest.

(iv) A Working Partner shall not be entitled to exchange any portion of its Working Partner Interest; provided, however, that BGC Partners may, with the written consent of a Majority in Interest, cause all or a portion of the outstanding

-43-

Working Partner Units to be exchangeable (including mandatorily exchangeable) with BGC Partners for shares of BGC Partners Class A Common Stock pursuant to Section 8.01(c)(iv); provided, however, that BGC Partners shall not be required to effectuate such an exchange if such Working Partner Interest shall be subject to any Encumbrance; provided, further, that in the case of any exchange of High Distribution II Units or High Distribution III Units by a Working Partner, BGC Partners shall not be required to effectuate such exchange unless and until such Partner shall have paid in full any then outstanding HDII Account or HDIII Account with respect to such Units. The terms and conditions on which such Working Partner Units shall become exchangeable (including the circumstances in which such Working Partner Units shall be mandatorily exchangeable and/or cease to be exchangeable) shall be determined by BGC Partners, with the written consent of a Majority in Interest.

(v) Provisions of this Article VIII that apply to the exchange of an entire Exchange Right Interest shall also apply to an exchange of a portion of an Exchange Right Interest. Each Exchange shall be expressed in terms of a number of Units underlying the Exchange Right Interest being exchanged. Cantor may, on one occasion, designate any Exchange or Exchanges made as of a single date or as part of a series of related transactions as being intended to qualify for tax-deferred treatment under Section 351 of the Code, in which case BGC Partners shall take such actions, at BGC Partners’ expense, as may be reasonably requested by Cantor to achieve such tax treatment. Subject to Section 4.09 of the Separation Agreement, BGC Partners acknowledges that for purposes of the foregoing, a request by Cantor to form a new parent holding company to which all of the holders of BGC Partners Common Stock are required to transfer their shares in connection with the consummation of an Exchange shall be a reasonable request.

(c) (i) Exchangeable Limited Partnership Interests issued on the date of this Agreement pursuant to the Contribution and any Exchangeable Limited Partnership Interests issued after the date of this Agreement shall be exchangeable for a number of shares of BGC Partners Class B Common Stock equal to the Exchange Ratio multiplied by the Units so exchanged; provided that, in the event that (A) the Electing Partner elects to receive BGC Partners Class A Common Stock and/or (B) there shall be not be any authorized and unissued shares of BGC Partners Class B Common Stock, such Exchangeable Limited Partnership Interests shall be exchangeable for a number of shares of BGC Partners Class A Common Stock equal to the Exchange Ratio multiplied by the Units so exchanged.

(ii) If a Founding Partner Interest shall have become exchangeable pursuant to Section 8.01(b)(ii), such Founding Partner Interest shall be exchangeable for a number of shares of BGC Partners Class A Common Stock equal to the Exchange Ratio multiplied by the Units so exchanged.

(iii) If an REU Interest shall have become exchangeable pursuant to Section 8.01(b)(iii), such REU Interest shall be exchangeable for a number of shares of BGC Partners Class A Common Stock equal to the Exchange Ratio multiplied by the Units so exchanged.

-44-

(iv) If a Working Partner Interest shall have become exchangeable pursuant to Section 8.01(b)(iv), such Working Partner Interest shall be exchangeable for a number of shares of BGC Partners Class A Common Stock equal to the Exchange Ratio multiplied by the Units so exchanged.

(d) A holder of an Exchange Right Interest is not entitled to any rights of a holder of BGC Partners Common Stock with respect to such Exchange Right Interest until such Interest shall have been exchanged therefor in accordance with this Article VIII.

(e) To exercise the Exchange Right, a holder of an Exchange Right Interest who elects to exercise its Exchange Right (an “Electing Partner”) shall prepare and deliver to BGC Partners and the Partnership a written request signed by such Electing Partner (i) stating the amount of Exchange Right Units, together with the Exchange Right Interests and a proportionate amount of Capital (or portion thereof), that such Electing Partner desires to exchange, (ii) stating the Business Day on which the Electing Partner shall elect to have such Exchange consummated in accordance with this Article VIII (the date so selected by the Electing Partner, the “Requested Exchange Effective Date”), (iii) solely in the case of Exchangeable Limited Partnership Interests, stating, whether such Electing Partner desires to receive BGC Partners Class A Common Stock in lieu of all or a portion of the BGC Partners Class B Common Stock otherwise issuable (and if so, the number of shares of BGC Partners Class A Common Stock such Electing Partner desires to receive), and (iv) representing, warranting and certifying to each of BGC Partners and Partnership that, as of the date of such notice and as of the Exchange Effective Date, (A) such Electing Partner is entitled to exchange the portion of the Exchange Right Units that the Electing Partner desires to exchange pursuant to this Article VIII, (B) such Electing Partner is the sole record and beneficial owner of such Exchange Right Units, together with Exchange Right Interests and a proportionate amount of Capital, free and clear of all Encumbrances other than those created by this Agreement, (C) upon consummation of the Exchange, BGC Partners will have all right, title and interest in and to the Exchange Right Interest and related Unit received in such exchange, free and clear of all Encumbrances (other than any created by this Agreement or under any agreement, contract, law or order to which BGC Partners is a party or otherwise subject), and (D) in the case of any Founding/Working Partner or REU Partner exercising an Exchange Right, an acknowledgement of such Partner’s responsibility for certain tax and tax related liabilities as provided in Section 12.07 (each such request, an “Exchange Request”). The General Partner shall effectuate such Exchange on the Requested Exchange Effective Date or otherwise promptly effectuate such Exchange (such date, the “Exchange Effective Date”). Each of BGC Partners and the General Partner shall have the right to determine whether any Exchange Request is proper or to waive any infraction, or any requirement, of these procedures. Once delivered, an Exchange Request shall be irrevocable.

(f) Each Exchange shall be consummated effective as of the close of BGC Partners’ business on the applicable Exchange Effective Date (such time, the “Exchange Effective Time”), and the Electing Partner shall be deemed to have become the holder of record of the applicable number of shares of BGC Partners Common Stock at such Exchange Effective Time, and all rights of the Electing Partner in respect of the portion of the Exchange Right Units, together with the Exchange Right Interest, and a proportionate

-45-

amount of Capital as determined pursuant to Section 8.01(h) so exchanged shall terminate at such Exchange Effective Time; provided, however, that the obligation of BGC Partners to consummate any Exchange shall be conditioned upon (i) the absence of any injunction, order, law or regulation of any governmental or regulatory authority of competent jurisdiction that prohibits the consummation of such Exchange or the redemption contemplated by Section 8.07 in accordance with its terms, (ii) the receipt of all material regulatory and governmental approvals (including registration under the Securities Act, or the availability of an exemption from the requirements for such registration and self regulatory approvals) that are required to consummate such Exchange and the redemption contemplated by Section 8.07 in accordance with its terms (and each of the parties involved in such Exchange shall use its reasonable best efforts to obtain all such approvals), (iii) the certifications set forth in Section 8.01(e) shall be true and correct when made and as of the Exchange Effective Time, and (iv) the redemption contemplated by Section 8.07 shall be capable of being consummated in accordance with the terms thereof.

(g) Upon receipt by BGC Partners of an Exchange Right Interest and related Exchange Right Units (or portion thereof) pursuant to any Exchange, the Exchange Right Interest and related Exchange Rights Units (or portion thereof) being so exchanged shall automatically be designated as a Regular Limited Partnership Interest and related Units (or portion thereof), shall have all rights and obligations of a holder of Regular Limited Partnership Interests and shall cease to be designated as an Exchange Right Interest (and for the avoidance of doubt, shall not be exchangeable pursuant to this Section 8.01).

(h) (i) In the case of an Exchange of an Exchangeable Limited Partnership Interest (or portion thereof) pursuant to Section 8.01(b)(i) or a Founding Partner Interest (or portion thereof) pursuant to Section 8.01(b)(ii), and subject to any additional adjustment as may be required under Section 8.01(i), the aggregate Capital Account of the Units so exchanged shall equal a pro rata portion of the total aggregate Capital Account of all Exchangeable Limited Partner Units and Founding Partner Units then outstanding, reflecting the portion of all such Exchangeable Limited Partner Units and Founding Partner Units then outstanding represented by the Units so exchanged. The aggregate Capital Account of the Electing Partner in such Partner’s remaining Units shall be reduced by an equivalent amount. If the aggregate Capital Account of such Electing Partner is insufficient to permit such a reduction without resulting in a negative Capital Account, the amount of such insufficiency shall be satisfied by reallocating Capital from the Capital Accounts of the Exchangeable Limited Partners and the Founding Partners to the Capital Account of the Units so exchanged, pro rata based on the number of Units underlying the outstanding Exchangeable Limited Partnership Interests and the Founding Partner Interests or based on other factors as determined by a Majority in Interest.

(ii) In the case of an Exchange of an REU Interest (or portion thereof) pursuant to Section 8.01(b)(iii) or a Working Partner Interest (or portion thereof) pursuant to Section 8.01(b)(iv), and subject to any additional adjustment as may be required under Section 8.01(i), the aggregate Capital Account of the Units so exchanged shall equal the Capital Account of the REU Interest (or portion thereof) or Working Partner Interest (or portion thereof), as the case may be, represented by such Units.

-46-

(i) If, prior to an Exchange of an Exchange Right Interest, there has been an allocation of items of income, gain, loss or deduction resulting from a Special Item, then (A) the Capital Account of the Units so exchanged shall be further adjusted so that Units received by BGC Partners in the Exchange shall not reflect any such allocation; and (B) any increase or decrease in the remaining Capital for all issued and outstanding Interests as a result of clause (A) of this sentence shall be allocated to the Capital Accounts of the Limited Partnership Interests (other than the Special Voting Limited Partnership Interest), pro rata in proportion to the number of Units underlying such Interests or in other proportion as determined by a Majority in Interest (it being the intention that, in all cases, BGC Partners, as the holder of the Special Voting Limited Partner Interest or otherwise, shall not bear the benefits and burdens of the Special Item). Such reallocation shall be effected in the manner determined by the General Partner with the written consent of a Majority in Interest.

SECTION 8.02. No Fractional Shares of BGC Partners Common Stock. Notwithstanding anything to the contrary herein, BGC Partners will not transfer any fractional shares of BGC Partners Common Stock upon any Exchange. In lieu thereof, in each Exchange, BGC Partners will transfer shares of BGC Partners Common Stock rounded to the nearest whole share.

SECTION 8.03. Taxes in Respect of an Exchange. In any Exchange, BGC Partners shall pay any documentary, stamp or similar issue or transfer tax due on the issue of the BGC Partners Common Stock upon such Exchange; provided that the Electing Partner shall pay any such tax that is due because such Electing Partner requests the shares of BGC Partners Common Stock to be issued in a name other than the holder’s name. BGC Partners may refuse to deliver the certificate representing BGC Partners Common Stock being transferred to a Person other than the Electing Partner until BGC Partners receives a sum sufficient to pay any tax that will be due because the shares are to be transferred to a Person other than the Electing Partner. Nothing herein shall preclude any tax withholding required by law or regulation. In addition, each Founding/Working Partner and REU Partner shall be responsible for all tax liabilities arising in connection with an Exchange as provided in Section 12.07.

SECTION 8.04. Reservation of BGC Partners Common Stock. BGC Partners covenants and agrees that it shall from time to time as may be necessary reserve, out of its authorized but unissued BGC Partners Class B Common Stock and BGC Partners Class A Common Stock, a sufficient number of shares of BGC Partners Class B Common Stock and BGC Partners Class A Common Stock solely to effect the exchange of all then outstanding Exchange Right Units together with the Exchange Right Interests and a proportionate amount of Capital into shares of BGC Partners Class B Common Stock and BGC Partners Class A Common Stock pursuant to the Exchanges (subject, in the case of BGC Partners Class B Common Stock, to the maximum number of shares authorized but unissued under the Certificate of Incorporation of BGC Partners as then in effect) and a sufficient number of shares of BGC Partners Class A Common Stock to effect the exchange of shares of BGC Partners Class B Common Stock issued or issuable in respect of Exchange Right Units together with the Exchange Right Interests and a proportionate amount of Capital. BGC Partners covenants and agrees that all shares of BGC Partners Class B Common Stock and BGC Partners Class A Common Stock issued in the Exchange will be duly authorized, validly issued, fully paid and nonassessable and will be free from pre-emptive rights and free of any Encumbrances. BGC Partners acknowledges and agrees that each additional issuance of Exchange Right Interests in accordance with this Agreement will be entitled to Exchange Right Units under this Article VIII.

-47-

SECTION 8.05. Compliance with Applicable Laws in the Exchange. BGC Partners shall use its reasonable best efforts promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of BGC Partners Class B Common Stock (or, if applicable, BGC Partners Class A Common Stock) upon Exchange of Exchange Right Units, together with the Exchange Right Interests and a proportionate amount of Capital, if any, and (to the extent BGC Partners Class A Common Stock is listed on a national securities exchange) to list or cause to have quoted such shares of BGC Partners Class A Common Stock (including BGC Partners Class A Common Stock issuable in exchange for any shares of BGC Partners Class B Common Stock to be issued hereunder) on each national securities exchange or on the Nasdaq Global Market or other over-the-counter market or such other market on which the BGC Partners Class A Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit BGC Partners to defer the listing of such BGC Partners Class A Common Stock until the first exchange of the Exchange Right Interests into BGC Partners Class A Common Stock (or, if applicable, BGC Partners Class B Common Stock exchangeable for BGC Partners Class A Common Stock) in accordance with the provisions of this Article VIII, BGC Partners shall use its reasonable best efforts to list such BGC Partners Class A Common Stock issuable upon Exchange of the Exchange Right Units together with the Exchange Right Interests and a proportionate amount of Capital or the BGC Partners Class B Common Stock issued in exchange for such Exchange Right Units together with the Exchange Right Interests and a proportionate amount of Capital in accordance with the requirements of such automated quotation system or exchange at such time.

SECTION 8.06. Adjustments to Exchange Ratio. (a) In the event that BGC Partners shall:

(i) pay a dividend in the form of shares of BGC Partners Common Stock or make a distribution on shares of BGC Partners Common Stock in the form of shares of BGC Partners Common Stock;

(ii) subdivide the outstanding shares of BGC Partners Common Stock into a greater number of shares;

(iii) combine the outstanding shares of BGC Partners Common Stock into a smaller number of shares;

(iv) make a distribution on shares of BGC Partners Common Stock in shares of its share capital other than BGC Partners Common Stock; or

(v) issue by reclassification of the outstanding shares of BGC Partners Common Stock any shares of its share capital;

for which there shall not be a corresponding adjustment in the number of Exchange Right Units (including pursuant to Section 4.11 of the Separation Agreement), then the Exchange Ratio in effect immediately prior to such action shall be adjusted so that the holder of an Exchange Right Unit who thereafter exchanged in accordance with this Article VIII shall receive the number of

-48-

shares of share capital of BGC Partners that it would have owned immediately following such action if it had exchanged its Exchange Right Units in full for shares of BGC Partners Common Stock immediately prior to such action; provided, however, that no such adjustment to the Exchange Ratio shall be made to the extent that such dividend, subdivision, combination, distribution or issuance pursuant to clauses (i) through (v) above was made to maintain the existing BGC Ratio pursuant to a reinvestment by BGC Partners or its Subsidiaries pursuant to Section 4.11(a)(iii) of the Separation Agreement.

(b) In the event of (i) any reclassification or change of shares of BGC Partners Common Stock issuable upon exchange of the Exchange Right Units (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in Section 8.06(a)); (ii) any consolidation or merger or combination to which BGC Partners is a party other than a merger in which BGC Partners is the continuing corporation and which does not result in any reclassification of, or change (other than in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of BGC Partners Common Stock; or (iii) any sale, transfer or other disposition of all or substantially all of the assets of BGC Partners, directly or indirectly, to any Person as a result of which holders of BGC Partners Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for BGC Partners Common Stock, then BGC Partners shall take all necessary action such that the Exchange Right Units then outstanding shall be exchangeable into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale, transfer or other disposition by a holder of the number of shares of BGC Partners Common Stock deliverable upon exchange of such Exchange Right Units immediately prior to such reclassification, change, combination, consolidation, merger, sale, transfer or other disposition. The provisions of this Section 8.06(b) shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances.

(c) In the event that the Partnership shall combine the outstanding Exchange Right Units into a smaller number of Exchange Right Units, the Exchange Ratio in effect immediately prior to such action shall be adjusted so that the holder of Exchange Right Units thereafter exchanged in accordance with this Article VIII may receive the number of shares of BGC Partners Common Stock that it would have owned immediately following such action if it had exchanged its Exchange Right Units in full for shares of BGC Partners Common Stock immediately prior to such action.

SECTION 8.07. Redemption for Opco Units. (a) Immediately following an Exchange of an Exchange Right Interest, the Partnership shall redeem the Exchange Right Interest and related Exchange Right Units received in the Exchange by BGC Partners (or any member of the BGC Partners Group to whom BGC Partners Transfers such Interests and related Units) in exchange for (A) a U.S. Opco Limited Partnership Interest (the “Acquired U.S. Opco Interest”) consisting of a number of U.S. Opco Units equal to (1) the number of shares of BGC Partners Common Stock issued in such Exchange multiplied by (2) the BGC Ratio as of immediately prior to the redemption of such Units and (B) a Global Opco Limited Partnership

(b) In the case of an Exchange of an Exchangeable Limited Partnership Interest or a Founding Partner Interest, (i) the Acquired U.S. Opco Interest shall consist of U.S. Opco Capital equal to (1) the total U.S. Opco Capital as of immediately prior to the applicable Exchange for all issued and outstanding U.S. Opco Units that were issued in connection with the issuance of any outstanding Exchangeable Limited Partnership Interest or Founding Partner Interest, divided by (2) the total number of issued and outstanding U.S. Opco Units as of immediately prior to the applicable Exchange that were issued in connection with the issuance of any outstanding Exchangeable Limited Partnership Interest or Founding Partner Interest, multiplied by (3) the number of U.S. Opco Units underlying such Acquired U.S. Opco Interest; (ii) the Acquired Global Opco Interest shall consist of Global Opco Capital equal to (1) the total Global Opco Capital as of immediately prior to the applicable Exchange for all issued and outstanding Global Opco Units that were issued in connection with the issuance of any outstanding Exchangeable Limited Partnership Interest or Founding Partner Interest, divided by (2) the total number of issued and outstanding Global Opco Units as of immediately prior to the applicable Exchange that were issued in connection with the issuance of any outstanding Exchangeable Limited Partnership Interest or Founding Partner Interest, multiplied by (3) the number of Global Opco Units underlying such Acquired Global Opco Interest; and (iii) the U.S. Opco Capital and Global Opco Capital of such Acquired U.S. Opco Interest and Global Opco Interest, as the case may be, shall be appropriately adjusted to reflect the impact of any Special Item (as defined in the U.S. Opco Limited Partnership Agreement and the Global Opco Limited Partnership Agreement, as the case may be) and the intention of the Parties for the Partnership (and not BGC Partners, as the holder of the Special Voting Limited Partner Interest or otherwise) to realize the economic benefits and burdens of such Special Item.

(d) In the case of an Exchange of a Working Partner Interest, (i) the Acquired U.S. Opco Interest shall consist of U.S. Opco Capital equal to (1) the total U.S. Opco Capital as of immediately prior to the applicable Exchange for all issued and outstanding U.S. Opco Units that were issued in connection with the issuance of any outstanding Working Partner Interest, divided by (2) the total number of issued and outstanding U.S. Opco Units as of immediately prior to the applicable Exchange that were issued in connection with the issuance of any outstanding Working Partner Interest, multiplied by (3) the number of U.S. Opco Units underlying such Acquired U.S. Opco Interest; (ii) the Acquired Global Opco Interest shall consist of Global Opco Capital equal to (1) the total Global Opco Capital as of immediately prior to the applicable Exchange for all issued and outstanding Global Opco Units that were issued in connection with the issuance of any outstanding Working Partner Interest, divided by (2) the total number of issued and outstanding Global Opco Units as of immediately prior to the applicable Exchange that were issued in connection with the issuance of any outstanding Working Partner Interest, multiplied by (3) the number of Global Opco Units underlying such Acquired Global Opco Interest; and (iii) the U.S. Opco Capital and Global Opco Capital of such Acquired U.S. Opco Interest and Global Opco Interest, as the case may be, shall be appropriately adjusted to reflect the impact of any Special Item (as defined in the U.S. Opco Limited Partnership Agreement and the Global Opco Limited Partnership Agreement, as the case may be) and the intention of the Parties for the Partnership (and not BGC Partners, as the holder of the Special Voting Limited Partner Interest or otherwise) to realize the economic benefits and burdens of such Special Item.

ARTICLE X

INDEMNIFICATION AND EXCULPATION

SECTION 10.01. Exculpation. Neither a General Partner nor any Affiliate or director or officer of a General Partner or any such Affiliate shall be personally liable to the Partnership or the Limited Partners for a breach of this Agreement or any fiduciary duty as a General Partner or as an Affiliate or director or officer of a General Partner or any such Affiliate, except to the extent such exemption from liability or limitation thereof is not permitted under the Act as the same exists or may hereafter be amended. Any repeal or modification of the immediately preceding sentence shall not adversely affect any right or protection of such Person existing hereunder with respect to any act or omission occurring prior to such repeal or modification. A General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisors selected by it and the opinion of any such Person as to matters which the General Partner reasonably believes to be within such Person’s professional or expert competence shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by the General Partner in good faith and in accordance with such opinion. A General Partner may exercise any of the powers granted to it by this Agreement and perform any of the obligations imposed on it hereunder either directly or by or through one or more agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner with due care.

SECTION 10.02. Indemnification. (a) 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

-53-

that he or she, or a Person of whom he or she is the legal representative, is or was a or has agreed to become a General Partner, or any director or officer of the General Partner or of the Partnership, or is or was serving at the request of the Partnership 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 surviving as a director, officer, employee or agent, shall be indemnified and held harmless by the Partnership to the fullest extent authorized by the General Corporation Law of the State of Delaware (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 Partnership to provide broader indemnification rights than said law permitted the Partnership to provide prior to such amendment), as if the Company were a corporation organized under the DGCL, against all expense, liability and loss (including attorneys’ fees and expenses, 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 Section 10.02(c), the Partnership 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 General Partner. The right to indemnification conferred in this Section 10.02 shall be a contract right and shall include the right to be paid by the Partnership the expenses, including attorneys’ fees and expenses, incurred in defending any such proceeding in advance of its financial disposition; provided, however, that if the applicable law requires that 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, service to an employee benefit plan) in advance of the final disposition of a proceeding shall be made only upon delivery to the Partnership 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 10.02 or otherwise. The Partnership may, by action of the General Partner, provide indemnification to employees and agents of the Partnership with the same scope and effect as the foregoing indemnification of directors and officers.

(b) To obtain indemnification under this Section 10.02, a claimant shall submit to the Partnership a written request, including therein or therewith such documentation and information as is reasonably available to the claimant and is 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 10.02(b), a determination, if required by applicable law, with respect to the claimant’s entitlement thereto shall be made as follows: (i) if requested by the claimant, by Independent Counsel (as hereinafter defined), or (ii) if no request is made by the claimant for a determination by Independent Counsel, (x) by the board of directors of BGC Partners by a majority vote of a quorum consisting of Disinterested Directors (as hereinafter defined), or (y) if a quorum of the board of directors of BGC Partners 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

-54-

of directors of BGC Partners, a copy of which shall be delivered to the claimant, or (z) if a quorum of Disinterested Directors so directs, by the affirmative vote of a Majority in Interest. In the event the determination of entitlement to indemnification is to be made by Independent Counsel at the request of the claimant, the Independent Counsel shall be selected by the board of directors of BGC Partners 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, as amended in 2003, 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 of BGC Partners. 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.

(c) If a claim under Section 10.02(a) is not paid in full by the Partnership within thirty (30) days after a written claim pursuant to Section 10.02(b) has been received by the Partnership, the claimant may at any time thereafter bring suit against the Partnership 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 Partnership) 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 Partnership to provide broader indemnification rights than it permitted the Partnership to provide prior to such amendment) for the Partnership to indemnify the claimant for the amount claimed if the Partnership were a corporation organized under the DGCL, but the burden of proving such defense shall be on the Partnership. Neither the failure of the Partnership (including the board of directors of BGC Partners, independent legal counsel or its holders of Interests) 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 Partnership (including the board of directors of BGC Partners or independent legal counsel or its holders of Interests) 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.

(d) If a determination shall have been made pursuant to Section 10.02(b) that the claimant is entitled to indemnification, the Partnership shall be bound by such determination in any judicial proceeding commenced pursuant to Section 10.02(c).

(e) The Partnership shall be precluded from asserting in any judicial proceeding commenced pursuant to Section 10.02(c) that the procedures and presumptions of this Section 10.02 are not valid, binding and enforceable and shall stipulate in such proceeding that the Partnership is bound by all the provisions of this Section 10.02.

(f) The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section 10.02

-55-

shall not be exclusive of any other right that any Person may have or hereafter acquire under any statute, provision of this Agreement, agreement, vote of the Exchangeable Limited Partners (by affirmative vote of a Majority in Interest) or Disinterested Directors or otherwise. No amendment or other modification of this Section 10.02 shall in any way diminish or adversely affect the rights of a General Partner, a Limited Partner or any directors, officers, employees or agents of the General Partner in respect of any occurrence or matter arising prior to any such repeal or modification.

(g) The Partnership may, to the extent authorized from time to time by the General Partner, grant rights to indemnification, and rights to be paid by the Partnership the expenses incurred in defending any proceeding in advance of its final disposition, to any employee or agent of the Partnership to the fullest extent of the provisions of this Section 10.02 with respect to the indemnification and advancement of expenses of a General Partner, a Limited Partner or any directors and officers of the General Partner.

(h) If any provision or provisions of this Section 10.02 shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Section 10.02 (including each portion of this Section 10.02 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 (ii) to the fullest extent possible, the provisions of this Section 10.02 (including each such portion of this Section 10.02 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.

(i) For purposes of this Article X:

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

(ii) “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 Partnership or the claimant in an action to determine the claimant’s rights under this Section 10.02.

(j) Any notice, request or other communication required or permitted to be given to the Partnership under this Section 10.02 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 General Partner and shall be effective only upon receipt by the General Partner.

SECTION 10.03. Insurance. The Partnership may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Partnership or another corporation, partnership, joint venture, trust or other enterprise against any expense,

-56-

liability or loss, whether or not the Partnership would have the power to indemnify such Person against such expense, liability or loss under the Act if the Partnership were a corporation organized under the DGCL. To the extent that the Partnership maintains any policy or policies providing such insurance, each such director or officer, and each such agent or employee to which rights of indemnification have been granted as provided in Section 10.02 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 10.04. Subrogation. In the event of payment of indemnification to a Person described in Section 10.02, the Partnership shall be subrogated to the extent of such payment to any right of recovery such person may have and such person, as a condition of receiving indemnification from the Partnership, shall execute all documents and do all things that the Partnership may deem necessary or desirable to perfect such right of recovery, including the execution of such documents necessary to enable the Partnership effectively to enforce any such recovery.

SECTION 10.05. No Duplication of Payments. The Partnership shall not be liable under this Article X to make any payment in connection with any claim made against a person described in Section 10.02 to the extent such Person has otherwise received payment (under any insurance policy or otherwise) of the amounts otherwise payable as indemnity hereunder.

SECTION 10.06. Survival . This Article X shall survive any termination of this Agreement.

ARTICLE XI

EXTRAORDINARY ITEMS

SECTION 11.01. Certain Arrangements Regarding Extraordinary Items. (a) The Partnership may, from time to time, receive extraordinary income items from non recurring events, including but not limited to (i) items that would be considered “extraordinary items” under U.S. generally accepted accounting principles and (ii) recoveries, by settlement, judgment, insurance reimbursement or otherwise, with respect to claims for expenses, costs and damages (including lost profits, but not including any recovery that does not result in monetary payments to the Partnership) attributable to extraordinary events affecting the Partnership (collectively, “Extraordinary Income Items”). Without limiting the foregoing, except as otherwise determined by the General Partner in its sole and absolute discretion, all after-tax income to the Partnership resulting from any transaction relating to shares of capital stock of any Affiliate owned by the Partnership, whether or not recurring in nature and whether hereafter arising or occurring prior to the date of this Agreement, including gains from the Partnership’s sale or deemed sale of such stock, may be treated by the General Partner as an Extraordinary Income Item (except to the extent that the transaction results in an offsetting item of expense or deduction to the Partnership or in items that are specially allocated pursuant to Sections 6.01(c) and 6.01(d)). The General Partner may determine, in its sole and absolute discretion, that all or a portion of any extraordinary expenditures from non-recurring events are to be treated for purposes of this Article XI as extraordinary expenditures (the “Extraordinary Expenditures”), including: (A) any

-57-

distribution or other payment (including a redemption payment) to a Partner, (B) the purchase price or other cost of acquiring any asset, (C) any other non-recurring expenditure of the Partnership, (D) items that would be considered “extraordinary items” under U.S. generally accepted accounting principles and (E) expenses, damages or costs attributable to extraordinary events affecting the Partnership (including actual, pending or threatened litigation). The General Partner may, in its sole and absolute discretion, establish one or more separate accounts for part or all of the after tax-portion of Extraordinary Income Items and Extraordinary Expenditures (each, an “Extraordinary Account”), which shall be maintained separately from the Capital Account of each Founding/Working Partner or REU Partner; provided, however, that the General Partner shall not deduct any Extraordinary Expenditure from any Extraordinary Account to the extent that doing so would result in a negative balance in such Extraordinary Account. To the extent that an item is treated as an Extraordinary Income Item or Extraordinary Expenditure, that item shall not directly or indirectly be included in the computation of the Partnership’s net income, gain, loss or deduction.

(b) Each Founding/Working Partner and each REU Partner shall have an Article XI term (the “Article XI Term”) with respect to each Unit held by such Partner and each Extraordinary Account. An Article XI Term of a Partner for any Extraordinary Account with respect to a Unit shall commence on the later of the date on which such Partner acquires such Unit or the date on which such Extraordinary Account is first created and ending on the date such Partner becomes a Terminated or Bankrupt Partner.

(c) A Terminated or Bankrupt Founding/Working Partner or REU Partner will receive a payment from each Extraordinary Account for each Unit held by such Partner on the date such Partner becomes a Terminated or Bankrupt Partner equal to the sum of: (i) the balance in each Extraordinary Account, (ii) the Extraordinary Percentage Interest in the Partnership represented by such Unit at the time such Partner becomes a Terminated or Bankrupt Partner and (iii) such Partner’s Vested Percentage with respect to such Extraordinary Account for such Unit.

(d) For purposes of this Article XI:

(i) “Vested Percentage” shall mean the amount equal to with respect to any Founding/Working Partner or REU Partner, 0% until (i) (A) such Partner’s Article XI Term with respect to such Extraordinary Account class for the Unit equals three (3) years or (B) with respect to a Founding/Working Partner holder of Grant Units only, the later of clause (A) or the continuous employment of such Founding/Working Partner for his, her or its Term of Employment (as defined in such Founding/Working Partner’s employment agreement with such Person, if any, entered into in connection with the issuance of the Matching Grant Units but excluding any automatic renewals thereof) (the later of the date specified in clause (A) or (B) being the “Initial Vesting Date”), (ii) 30% as of the Initial Vesting Date and increasing by 10% on each yearly anniversary of such date until such Partner’s Vested Percentage for such Extraordinary Account for such Unit equals 100%; provided that the General Partner in its sole and absolute discretion may accelerate the vesting of a Founding/Working Partner’s or REU Partner’s Extraordinary Account and may accelerate the distribution of such vested amounts.

-58-

(ii) At any time of determination, “Extraordinary Percentage Interest” shall mean the amount equal to with respect to any Founding/Working Partner or REU Partner, the percentage calculated by dividing the number of Units (including Hypothetical Units treated as being outstanding) held by such Partner by the number of Units (including Hypothetical Units treated as being outstanding) of the Partnership then outstanding. Such payments will be made in up to five (5) equal annual installments, as determined by the General Partner, commencing within one (1) year of the date on which a Founding/Working Partner or an REU Partner, as the case may be, becomes a Terminated or Bankrupt Partner; provided that the Terminated or Bankrupt Partner has not violated its Partner Obligations or engaged in any Competitive Activity, prior to the date such payments are completed, and shall be subject to prepayment (including payment prior to the Termination of a Partner) at the sole and absolute discretion of the General Partner at any time.

(iii) Upon the Termination of any Founding/Working Partner or REU Partner, there shall be treated as issued to Cantor a number of Founding/Working Partner Units or REU Partner Units, as the case may be (the “Hypothetical Units”), equal to the product of (1) the number of Units held by such Partner immediately prior to such Termination and (2) 100% minus such Partner’s Vested Percentage at the time of such Termination; provided that such Partner’s Vested Percentage shall be adjusted (but not below zero (0)) to reflect the portion of the Vested Percentage that is actually paid to such Partner in connection with its Termination.

(e) Nothing in this Article XI shall affect the amount of money or property distributable to a Partner upon the liquidation of the Partnership.

(f) Notwithstanding anything to the contrary contained herein or otherwise, the General Partner is authorized (upon the approval of the Exchangeable Limited Partners (by affirmative vote of a Majority in Interest)) to amend this Agreement without the consent of the Limited Partners to the extent reasonably necessary to carry out the purposes of this Article XI.

ARTICLE XII

FOUNDING PARTNERS, WORKING PARTNERS AND REU PARTNERS

SECTION 12.01. Units. (a) General.

(i) Grant Units. Grant Units shall represent Founding/Working Partner Interests in the Partnership. Except as specifically provided to the contrary herein or in the agreements or other written materials executed by the General Partner relating to the grant of any Grant Units, it is intended that, for all purposes under this Agreement, Grant Units and the holders thereof shall have the same rights, privileges and obligations and shall be subject to the same restrictions, as High Distribution Units and the holders thereof; provided, however, that subject to the other provisions of this Agreement, the Partnership may issue Grant Units and create a Grant Tax Payment Account with other rights and limitations (including performance criteria, earnings

-59-

limitations, and vesting requirements), upon the written consent of the General Partner and the holders of such Units. Any such rights and limitations shall be taken into account in applying the provisions of this Agreement.

(ii) Matching Grant Units. Matching Grant Units shall represent Founding/Working Partner Interests in the Partnership. Matching Grant Units may be issued, at the sole and absolute discretion of the General Partner, in connection with the purchase of Units by any Partner and in such amounts that the General Partner shall determine in its sole and absolute discretion. Except as specifically provided to the contrary herein or as in the agreements or other written materials executed by the General Partner relating to the grant of any Matching Grant Units, it is intended that, for all purposes under this Agreement, Matching Grant Units and the holders thereof shall have the same rights, privileges, and obligations and shall be subject to the same restrictions, as High Distribution Units and the holders thereof; provided, however, that subject to the other provisions of this Agreement, the Partnership may issue Matching Grant Units and create a Matching Grant Tax Payment Account with other rights and limitations (including performance criteria, earnings limitations, and vesting requirements), upon the written consent of the General Partner and the holders of such Units. Any such rights and limitations shall be taken into account in applying the provisions of the Agreement.

(iii) High Distribution Units. High Distribution Units shall represent Founding/Working Partner Interests in the Partnership.

(iv) REUs. REUs shall represent REU Interests in the Partnership.

(b) High Distribution II Units. (i) Except as otherwise provided in this Section 12.01(b) or elsewhere in this Agreement, holders of High Distribution II Units shall have the same rights, privileges, and obligations as, and shall be subject to the same restrictions as, High Distribution Units.

(ii) The Partnership shall maintain an HDII Account with respect to each holder of High Distribution II Units. The HDII Account shall initially be equal to the amount per Unit mutually agreed by the Founding/Working Partner and the General Partner upon the issuance of any High Distribution II Units, subject to Section 12.01(b)(ix) and shall be adjusted as hereinafter provided. High Distribution II Units held as a result of modification of High Distribution Units shall, solely for purposes of this Section 12.01(b), be treated as issued on the date of such modification, except that such Units shall be treated as having been held by such Founding/Working Partner since the date the High Distribution Units were originally purchased for purposes of determining the amount distributable to a holder of High Distribution II Units pursuant to Section 12.01(b)(viii).

(A) Each HDII Account shall be reduced, but not below zero (0), by (x) any cash contributed to the Partnership by a holder of High Distribution II Units and designated as an HDII Contribution or (y) any reduction in distributions to such Founding/Working Partner pursuant to

-60-

Section 12.01(b)(v), 12.01(b)(vi) or 12.01(b)(viii) (all amounts referred to in (x) and (y) shall be defined as “HDII Contributions”).

(B) In the event that a Loss is allocated with respect to a Founding/Working Partner’s High Distribution II Units during any period, such Founding/Working Partner’s HDII Account shall be increased by the smaller of (x) the amount of such Loss and (y) the amount of such Founding/Working Partner’s HDII Special Allocation.

(iii) Pursuant to Section 2(k) of Exhibit D to this Agreement, a portion of the items of loss or deduction of the Partnership for each period shall specifically be allocated to each Founding/Working Partner holding High Distribution II Units with a positive HDII Account. Such portion (the “HDII Special Allocation”) shall be equal to the product of (1) the balance of such HDII Account and (2) the rate mutually agreed by the Founding/Working Partner and the General Partner from time to time (the “HDII Special Allocation Rate”). Such HDII Special Allocation Rate may be fixed or established by formula.

(iv) A Founding/Working Partner’s HDII Account for each Unit must periodically be reduced to the level specified in a schedule mutually agreed by the Founding/Working Partner and the General Partner. If no schedule is agreed, the HDII Account shall be reduced by an amount sufficient so that the HDII Account is (i) no greater than 75% of its original value on the first December 15th after such Unit’s issuance; (ii) no greater than 50% of its original value on the second December 15th after such Unit’s issuance; (iii) no greater than 25% of its original value on the third December 15th after such Unit’s issuance; and (iv) zero (0) on the fourth December 15th after such Unit’s issuance; provided, however, that any such December 15th date may be extended at the sole and absolute discretion of the General Partner to any later date in December of such year. To the extent that any HDII Account exceeds the relevant level set forth in the schedule or, if no schedule is agreed upon, the relevant level specified in the preceding sentence, such Founding/Working Partner’s HDII Account shall be reduced through adjustments to distributions pursuant to Section 12.01(b)(v) or 12.01(b)(vi). Reductions required to be made pursuant to this Section 12.01(b)(iv) shall be referred to as an “HDII Account Reduction Obligation.”

(v) Amounts distributable to any Founding/Working Partner holding High Distribution II Units for any period shall be reduced, but not below zero (0), by the amount of any HDII Account Reduction Obligation that has not previously been satisfied. To the extent that any HDII Account Reduction Obligation for any date exceeds the amount, if any, that would otherwise be distributed to such Founding/Working Partner within five (5) days of such date, after application of any withholding tax or other payments on behalf of such Founding/Working Partner pursuant to Section 5.09, such Founding/Working Partner shall be required to make additional HDII Contributions to the Partnership pursuant to Section 12.01(b) in an amount equal to such excess.

-61-

(vi) The General Partner may reduce any distribution otherwise payable to any holder of High Distribution II Units by an amount not to exceed the HDII Account Reduction Obligation for any date during the fiscal year that includes such distribution. Such reduction shall be made after application of Section 12.01(b)(iv). In applying this Section 12.01(b)(vi), the General Partner may deem such Founding/Working Partner to have elected to receive a distribution equal to 100% of the Estimated Income allocable to such Founding/Working Partner for such period.

(vii) Notwithstanding anything to the contrary contained in this Agreement, no additional Units shall be issued to a Founding/Working Partner holding High Distribution II Units as a result of any HDII Contribution occurring by way of cash contributions and reductions in amounts distributable to such Founding/Working Partner under Section 12.01(b)(v), 12.01(b)(vi) or 12.01(b)(viii).

(viii) In the event of the redemption of all or a portion of a Founding/Working Partner’s High Distribution II Units pursuant to Section 3.03, 9.02 or 12.05 or otherwise in accordance with this Agreement, the amount distributable to a Founding/Working Partner shall be reduced, but not below zero (0), by the HDII Account. In the event of the redemption of all of a Founding/Working Partner’s High Distribution II Units, the Founding/Working Partner’s HDII Account shall become immediately payable to the Partnership in full. In the event of the redemption of all or a portion of a Founding Partner’s High Distribution II Units, (a) an amount equal to the Founding Partner’s CFLP HDII Account with respect to such Units shall be paid to Cantor rather than being distributed to such Founding Partner on such date with respect to such Units and (b) if such High Distribution II Units called for redemption are purchased by Cantor pursuant to Section 12.02 or 12.03, the amount payable by Cantor to such Founding Partner or the Partnership for such Units shall be reduced by an amount equal to the Founding Partner’s CFLP HDII Account with respect to such Unit not theretofore paid by the Partner pursuant to this Section 12.01(b).

(ix) Any High Distribution II Unit that is designated as a Founding Partner Unit shall continue to have a CFLP HDII Account, CFLP HDII Special Allocation Rate and CFLP HDII Account Reduction Obligation, and the holder of such High Distribution II Unit shall satisfy its obligations to Cantor relating to such Unit by the application of any distributions that would be subject to reduction and any contributions that would be made by such holder under this Section 12.01(b), were such holder’s High Distribution II Unit to have an HDII Account, a HDII Special Allocation Rate and an HDII Account Reduction Obligation, equal to those it has to Cantor (and, in the case of any loss specially allocated to such holder by the Partnership reflecting the HDII Account Reduction Obligation it would have, an equivalent amount of income shall be allocated by the Partnership to Cantor). Any payment by a Partner to Cantor in respect of its CFLP HDII Account Reduction Obligation pursuant to this paragraph shall result in an increase in such Partner’s Capital Account in the Partnership (such payment to be treated, for purposes of maintaining Capital Accounts, as a capital contribution by such Partner to the Partnership and a distribution by the Partnership to Cantor).

-62-

(x) Notwithstanding anything to the contrary contained in this Agreement, any Founding/Working Partner holding High Distribution II Units shall be required to make additional HDII Contributions to the Partnership by way of cash contributions and by reductions in amounts distributable to such Partner as provided in Sections 12.01(b)(v), 12.01(b)(vi) and 12.01(b)(viii). Such contributions must be made within five days of the General Partner notifying such High Distribution II Unitholder of its obligation hereunder. In the event that the required contribution is not made, the General Partner may, in its sole and absolute discretion, redeem all or a portion of such Founding/Working Partner’s High Distribution II Units, declare the High Distribution Unit II Unitholder to be in default under this Agreement, or take any other action available to it at law or in equity to enforce the obligation described in this Section 12.01(b)(x), including, without limitation, seeking enforcement of such obligation in any forum and in any jurisdiction (and each High Distribution II Unitholder hereby irrevocably submits to the jurisdiction of any such forum or jurisdiction), notwithstanding the jurisdictional provisions contained in Section 13.04 hereof, including the payment of legal fees and expenses related thereto. Any Partner not making a required contribution shall pay interest to the Partnership at a rate determined by the General Partner, and such interest payments shall not be treated as capital contributions hereunder or as part of such Partner’s Capital Account.

(c) High Distribution III Units. High Distribution III Units and holders of High Distribution III Units shall have the same rights, privileges and obligations as, and shall be subject to the same restrictions as, High Distribution II Units and holders of High Distribution II Units, and High Distribution III Units that are Founding Partner Units shall be treated in the same manner as High Distribution II Units that are Founding Partner Units (including the obligation of a holder of High Distribution III Units to Cantor pursuant to Sections 12.01(b)(viii) and 12.01(b)(ix)); provided that High Distribution III Units shall always have a Base Amount of zero (0) and shall have an HDIII Account in lieu of an HDII Account, which Account shall be subject to mandatory annual reduction on each anniversary of the date of issuance of the applicable High Distribution III Unit (or on such other date as the General Partner, acting in its sole and absolute discretion, in writing shall establish) (any such date, a “Reduction Date”) to such amount as specified on a schedule mutually agreed by the Founding/Working Partner and the General Partner, acting in its sole and absolute discretion, or if no schedule shall be agreed upon, to not greater than 5/6 of the original HDIII Account on the first Reduction Date; not greater than 2/3 of the original HDIII Account on the second Reduction Date; not greater than 1/2 of the original HDIII Account on the third Reduction Date; not greater than 1/3 of the original HDIII Account on the fourth Reduction Date; not greater than 1/6 of the original HDIII Account on the fifth Reduction Date; and zero (0) on the sixth Reduction Date. Reductions required to be made pursuant to this Section 12.01(c) shall be referred to as an “HDIII Account Reduction Obligation.” Each High Distribution III Unit shall have a HDIII Special Allocation Rate and HDIII Account Reduction Obligation in lieu of a HDII Special Allocation Rate and HDII Account Reduction Obligation. Until such time as a holder of High Distribution III Units shall have reduced his, her or its HDIII Account to zero (0), the High Distribution III Units held by such Founding/Working Partner shall not have any of the voting rights provided to Limited Partners in this Agreement.

-63-

(d) High Distribution IV Units. Holders of High Distribution IV Units shall have the same rights, privileges and obligations as, and shall be subject to the same restrictions as, holders of High Distribution Units; provided that High Distribution IV Units shall always have a Base Amount of zero (0); provided, further, that High Distribution IV Units that are designated as Founding Partner Units shall have a “HDIV Tax Payment Account” in an amount equal to the Cantor HDIV Tax Payment Account of the limited partner units in Cantor that were redeemed in exchange for such High Distribution IV Units in the Cantor Redemption, and a holder of High Distribution IV Units shall be entitled to receive payments from the Partnership with respect to such HDIV Tax Payment Account in amounts, at times and on terms equivalent to what would have applied to such Founding/Working Partner holding High Distribution IV Units had such Founding/Working Partner holding High Distribution IV Units continued to hold Cantor High Distribution IV Units and not been subject to the Cantor Redemption with any HDIV Tax Payment Account to be subject to payment upon the same terms and conditions as are provided in Section 12.02(g) for a Grant Tax Payment Account.

SECTION 12.02. Transfers of Founding Partner Interests, Working Partner Interests and REU Interests. (a) Effect of Termination or Bankruptcy of Founding/Working Partners or REU Partners. (i) Termination and Bankruptcy of Founding Partners.

(A) Except as otherwise agreed to by each of the General Partner, the Exchangeable Limited Partners (by Majority in Interest) and the applicable Founding Partner or as otherwise expressly provided herein, upon any Termination or Bankruptcy of a Founding Partner (or the Termination or Bankruptcy of the beneficial owner of the stock or other ownership interest of any such Founding Partner that is a corporation or other entity), (1) the portion of the Founding Partner Interest held by such Partner that shall have become exchangeable pursuant to Section 8.01(b)(ii), if any, shall automatically be Exchanged with BGC Partners for BGC Partners Class A Common Stock on the terms set forth in Sections 8.01(f), 8.01(g) and 8.01(h); provided that the General Partner shall determine the Exchange Effective Date (which date shall be on the date of such Termination or Bankruptcy or as promptly as practicable thereafter and which may be later than the Calculation Date); and (2) the portion of the Founding Partner Interest that shall not have become exchangeable pursuant to Section 8.01(b)(ii) shall be purchased or redeemed from such Founding Partner or his, her or its Personal Representative by the Partnership, and such Founding Partner or his, her or its Personal Representative shall sell to the Partnership all of the Founding Partner Interest held by such Founding Partner at the time of Termination or Bankruptcy on the terms and conditions set forth in Section 12.02. With the consent of Cantor and the General Partner, the Partnership may assign by written instrument its right to purchase such Founding Partner Interest pursuant to this Section 12.02 to another Partner.

(B) At the time of purchase of a Founding Partner Interest by the Partnership pursuant to this Article XII, including Section 12.02(a)(i)(A), the Partnership shall provide written notice to Cantor of such purchase as promptly as practicable, and Cantor shall have a right to purchase (or to assign to any member

-64-

of the Cantor Group the right to purchase) all or a portion of such Founding Partner Interest from the Partnership (it being understood that such purchase price shall be proportionately reduced to the extent that only a portion of the Founding Partner Interest is being acquired). The price to be paid by Cantor (or the other member of the Cantor Group acquiring such Founding Partner Interest, as the case may be) for the purchase of a Founding Partner Interest pursuant to this Section 12.02(a)(i)(B) shall be equal to the lesser of (1) the amount that the Partnership would be required to pay to redeem or purchase such Founding Partner Interest were the Partnership to redeem or purchase such Founding Partner Interest pursuant to the provisions of this Section 12.02 (assuming such Founding Partner Interest were a Working Partner Interest) and (2) the amount equal to (x) the number of Units underlying such Founding Partner Interest, multiplied by (y) the Exchange Ratio as of the date of such purchase, multiplied by (z) the Current Market Price as of the date of such purchase. Cantor (or the other member of the Cantor Group acquiring such Founding Partner Interest, as the case may be) may pay for such price using cash, Publicly Traded Shares (valued at the average of the closing prices of such shares (as reported by the Nasdaq Global Market or any other national securities exchange or quotation system on which such shares are then listed or quoted) during the 10-trading-day period immediately preceding each payment (or by such other fair and reasonable pricing method as may be selected by Cantor)), or other property valued at its then-fair market value, as determined by Cantor in its sole and absolute discretion, or a combination of the foregoing. Notwithstanding anything to the contrary set forth in this Agreement, the Parties agree that, if Cantor (or the other member of the Cantor Group acquiring such Founding Partner Interest, as the case may be) shall purchase a Founding Partner Interest pursuant to this Section 12.02(a)(i)(B) at a price equal to clause (2) above, neither Cantor, any member of the Cantor Group nor the Partnership or any other Person be obligated to pay the holder of such Founding Partner Interest any amount in excess of the amount set forth in clause (2) above. Cantor shall respond as promptly as practicable to the Partnership after receipt of the written notice provided by the Partnership as to whether it is electing to exercise its rights pursuant to this Section 12.02(a)(i)(B) with respect to a Founding Partner Interest. Pursuant to Section 4.03(c)(iii), any Founding Partner Interest acquired by a Cantor Company pursuant to this Section 12.02(a)(i)(B) shall cause such Founding Partner Interest and related Units (or portion thereof) to automatically be designated as an Exchangeable Limited Partnership Interest and the related Units (or portion thereof) shall automatically be designated as Exchangeable Limited Partnership Units. The Cantor Company acquiring such Interest shall have all rights and obligations of a holder of Exchangeable Limited Partnership Interest with respect to such Interest, and such Exchangeable Limited Partnership Interest shall not be subject to the redemption provisions of this Article XII.

(ii) Termination and Bankruptcy of Working Partners.

(A) Except as otherwise agreed to by each of the General Partner and the applicable Working Partner or as otherwise expressly provided

-65-

herein, upon any Termination or Bankruptcy of a Working Partner (or the Termination or Bankruptcy of the beneficial owner of the stock or other ownership interest of any such Working Partner that is a corporation or other entity), (1) the portion of the Working Partner Interest held by such Partner that shall have become exchangeable pursuant to Section 8.01(b)(iv), if any, shall automatically be Exchanged with BGC Partners for BGC Partners Class A Common Stock on the terms set forth in Sections 8.01(f), 8.01(g) and 8.01(h); provided that the General Partner shall determine the Exchange Effective Date (which date shall be on the date of such Termination or Bankruptcy or as promptly as practicable thereafter and which may be later than the Calculation Date); and (2) the portion of the Working Partner Interest that shall not have become exchangeable pursuant to Section 8.01(b)(iv) shall be purchased or redeemed from such Working Partner by the Partnership, or his, her or its Personal Representative, and such Working Partner, or his, her or its Personal Representative shall sell to the Partnership, all of the Working Partner Interest held by such Working Partner at the time of Termination or Bankruptcy on the terms and conditions set forth in Section 12.02. With the consent of the General Partner, the Partnership may assign by written instrument its right to purchase such Working Partner Interest pursuant to this Section 12.02 to another Partner.

(B) If the Partnership elects to assign its purchase rights with respect to any Working Partner Interest to another Partner pursuant to Section 12.02(a)(ii)(A), the Partnership shall provide written notice to Cantor of such election as promptly as practicable, and Cantor shall have a right to purchase (or to assign to any member of the Cantor Group the right to purchase) all or a portion of such Interest from the Partnership, on the same terms that such Partner would have a right to purchase such Interest. Cantor shall respond as promptly as practicable to the Partnership after receipt of the written notice provided by the Partnership as to whether it is electing to exercise its right to purchase provided in this Section 12.02(a)(ii)(B) with respect to such Working Partner Interest.

(iii) Termination and Bankruptcy of REU Partners.

(A) Except as otherwise agreed to by each of the General Partner and the applicable REU Partner or as otherwise expressly provided herein, upon any Termination or Bankruptcy of an REU Partner (or the Termination or Bankruptcy of the beneficial owner of the stock or other ownership interest of any such REU Partner that is a corporation or other entity), (1) the portion of the REU Interest held by such Partner that shall have become exchangeable pursuant to Section 8.01(b)(iii) shall automatically be Exchanged with BGC Partners for BGC Partners Class A Common Stock on the terms set forth in Sections 8.01(f), 8.01(g) and 8.01(h); provided that the General Partner shall determine the Exchange Effective Date (which date shall be on the date of such Termination or Bankruptcy or as promptly as practicable thereafter and which may be later than the Calculation Date); and (2) the portion of the REU Interest held by such Partner that shall not have become exchangeable pursuant to Section 8.01(b)(iii) shall be purchased and redeemed by the Partnership, and such REU Partner, or

-66-

his, her or its Personal Representative shall sell to the Partnership, all of such portion of the REU Interest on the terms and conditions set forth in Section 12.02. With the consent of the General Partner, the Partnership may assign by written instrument its right to purchase such portion of the REU Interest pursuant to this Section 12.02 to another Partner.

(B) If the Partnership elects to assign its purchase rights with respect to any REU Interest to another Partner pursuant to Section 12.02(a)(iii)(A), the Partnership shall provide written notice to Cantor of such election as promptly as practicable, and Cantor shall have a right to purchase (or to assign to any member of the Cantor Group the right to purchase) all or a portion of such Interest from the Partnership, on the same terms that such Partner would have a right to purchase such Interest. Cantor shall respond as promptly as practicable to the Partnership after receipt of the written notice provided by the Partnership as to whether it is electing to exercise its right to purchase provided in this Section 12.02(a)(iii)(B) with respect to such REU Interest.

(iv) Other.

(A) Solely for purposes of this Section 12.02, all references to Founding Partners, Working Partners, Founding/Working Partners or REU Partners shall include any Terminated or Bankrupt former Founding Partners, Working Partners, Founding/Working Partners or REU Partners, unless the context clearly indicates otherwise.

(B) Each Founding/Working Partner and each REU Partner acknowledges and recognizes that, during the period that such Founding/Working Partner or REU Partner, as the case may be, is a Partner, he, she or it (or their beneficial owner) will be privy to trade secrets, client secrets and confidential proprietary information critical to the success of the business of the Partnership and the Affiliated Entities and will have an extraordinary opportunity to participate in the growth of the business of the Partnership. Each Founding/Working Partner and each REU Partner also agrees that certain actions taken by the Founding/Working Partner or REU Partner, as the case may be, including, violating its Partner Obligations or engaging in a Competitive Activity while a Founding/Working Partner or REU Partner, as the case may be, is a Partner or otherwise during the four-year period immediately following the date on which such Person ceases, for any reason, to be a Partner would harm the Partnership or the Affiliated Entities. Accordingly, in consideration of being afforded the opportunity to become a Partner, each Founding/Working Partner and each REU Partner agrees to the economic terms set forth in this Section 12.02.

(C) Each Founding/Working Partner and each REU acknowledges that this Section 12.02 is intended solely to reflect the economic agreement between the Founding/Working Partners and the REU Partners, as the case may be, with respect to amounts payable upon such Partner’s Bankruptcy or

-67-

Termination. Nothing in this Section 12.02 shall be considered or interpreted as restricting the ability of a former Partner in any way from engaging in any Competitive Activity, or in other employment of any nature whatsoever, subject in either case to the restrictions elsewhere in this Agreement (including Sections 3.03 and 13.06). The provisions of this Section 12.02 shall be in addition to, and not in substitution for, any other provision of this Agreement or any agreement to which the Founding/Working Partner or REU Partner, as the case may be, is subject pursuant to the terms of any other agreement with the Partnership or any Affiliated Entity and shall not abrogate any provisions contained in this Agreement or any other such agreement.

(D) Each Founding/Working Partner and each REU Partner consents to the economic terms of this Section 12.02 and agrees that, subject to Section 2.09(c), a Founding/Working Partner and an REU Partner, as the case may be, who does not engage in a Competitive Activity or otherwise breach a Partner Obligation during the four-year period immediately following the date such Person cease, for any reason, to be a Partner, shall be entitled, subject to any other provision of this Agreement (including Section 2.09(c)) and any other remedies at law or in equity for a breach by such Partner of any other provision of this Agreement, to all amounts payable pursuant to Sections 12.02(b) and 12.02(c). Subject to Sections 2.09(c) and 3.03, a Founding/Working Partner or an REU Partner, as the case may be, who chooses to engage, or engages, in a Competitive Activity or otherwise breaches a Partner Obligation shall be entitled to receive all amounts payable pursuant to Section 12.02(b) and shall be entitled to receive Additional Amounts as are provided in Section 12.02(c) to the extent that such amounts are payable prior to the date on which such Partner first participates in a Competitive Activity or otherwise breaches a Partner Obligation. Each Founding/Working Partner and each REU Partner agrees that the amounts that such a Founding/Working Partner or REU Partner, as the case may be, will receive upon withdrawing from the Partnership represent full and complete payment in liquidation of such Partner’s interest in the property of the Partnership, taking into account such Partner’s share of Partnership liabilities. Such amount will not include any payment for a Founding/Working Partner’s interest or an REU Partner’s interest, as the case may be, in the unrealized receivables or goodwill of the Partnership.

(b) Payment of Base Amount. (i) Except as otherwise expressly set forth herein, the purchase price to be paid by the Partnership (or the Partner to which the purchase right had been assigned, as applicable) for the Founding/Working Partner Interest or the REU Interest, as the case may be, purchased or redeemed pursuant to Section 12.02(a) shall equal the Base Amount of such Founding/Working Partner Interest or REU Interest, as the case may be, as of the Calculation Date; provided that the Partnership may, in the sole and absolute discretion of the General Partner, deduct therefrom the Adjustment Amount in whole or in part.

(ii) If (A) a Founding/Working Partner (other than a holder of Grant Units or Matching Grant Units) or REU Partner, as the case may be, shall become a

-68-

Terminated or Bankrupt Partner, or (B) a Founding/Working Partner holding Grant Units or Matching Grant Units shall become a Terminated Founding/Working Partner, in each case of clause (A) or (B), such Partner shall receive the applicable Base Amount at such time as the Partnership shall elect to tender payment, but in no event later than 90 days after the date of Termination or Bankruptcy of such Partner, as applicable, or at such later date as may soonest be practicable in view of the administration of the estate of a deceased or Bankrupt Founding/Working Partner or REU Partner, as the case may be (such date referred to herein as the “Payment Date”).

(iii) The “Base Amount” means: (1) with respect to any Founding Partner Unit received pursuant to the Cantor Redemption or any REU Interest, an amount equal to zero; and (2) with respect to all of the Working Partner Interest held by a Terminated or Bankrupt Working Partner on the date such Working Partner becomes a Terminated or Bankrupt Working Partner, an amount equal to the smallest of:

(A) the Working Partner’s Adjusted Capital Account for the entire Interest held by such Working Partner less $50,000;

(B) three quarters (3/4) of the Working Partner’s Adjusted Capital Account for all Units held by such Working Partner (one third (1/3) with respect to Units which are Under Three-Year Units); and the amount equal to: (A) with respect to all Pre Five Year Units held by such Working Partner, the Capital Return Account; plus (B) with respect to all Five Year Units held by such Working Partner, the Capital Return Account plus one quarter (1/4) of the Adjusted Capital Account Surplus with respect to such Units, less any Excess Prior Distributions with respect to such Units (but not in excess of the Adjusted Capital Account with respect to such Units); plus (C) with respect to all Ten Year Units held by such Working Partner, the Capital Return Account plus one third (1/3) of the Adjusted Capital Account Surplus with respect to such Units, less any Excess Prior Distributions with respect to such Units (but not in excess of the Adjusted Capital Account with respect to such Units).

In no event shall the Base Amount be negative. For purposes of the calculation of all amounts under this Section 12.02(b)(iii), all adjustments and allocations pursuant to any other section of this Agreement shall be deemed made pro rata with respect to all Units held by a Partner.

(iv) Any Adjusted Capital Account with respect to the Founding Partner Units, REUs, Grant Units, Matching Grant Units, High Distribution III Units and High Distribution IV Units as of the Calculation Date (after any reduction for any Adjustment Amount) shall be paid as Additional Amounts in accordance with and subject to the terms of Section 12.02(c).

(v) In the event of the redemption of all or a portion of a Founding/Working Partner’s High Distribution II Units, (a) an amount equal to the

-69-

Founding/Working Partner’s CFLP HDII Account with respect to such Units shall be paid to Cantor rather than being distributed to such Founding/Working Partner on such date with respect to such Units or (b) if such High Distribution II Units called for redemption are purchased by Cantor, the amount payable by Cantor to such Founding/Working Partner or the Partnership for such Units shall be reduced by an amount equal to the Founding/Working Partner’s CFLP HDII Account with respect to such Units.

(vi) Solely for purposes of making the calculation required by this Section 12.02, the General Partner may to the extent it deems appropriate include a Founding/Working Partner’s HDII Account in its Adjusted Capital Account.

(c) Payment of Additional Amounts. (i) On each of the first, second, third and fourth anniversaries of the Payment Date (or at such earlier time as is determined by the General Partner in its sole and absolute discretion), a Founding/Working Partner or REU Partner, as the case may be, will be entitled to receive payment of one fourth (1/4) of such Partner’s Additional Amounts plus an amount equal to interest determined pursuant to Section 12.02(c)(iv); provided that such Partner (or in the case of a corporate or other entity Partner, the majority owner of such Partner) has not engaged in any Competitive Activity or otherwise breached a Partner Obligation prior to the date such payment is due.

(ii) A Partner’s “Additional Amounts” shall mean the amount equal to the excess, if any, of (A) such Partner’s Adjusted Capital Account with respect to such Partner’s entire Interest held by such Partner (which may be reduced in whole or in part, in the sole and absolute discretion of the General Partner, by the Adjustment Amount), minus (B) the amount, if any, payable to such Partner pursuant to Section 12.02(b)(i).

(iii) For purposes of this Agreement, a Founding/Working Partner or REU Partner, as the case may be, shall be considered to have engaged in a competitive activity if such Partner (including by or through his, her or its Affiliates) during the four-year period immediately following the date such Person ceases, for any reason, to be a Partner (collectively, clauses (A) through (E), the “Competitive Activities”):

(A) directly or indirectly, or by action in concert with others, solicits, induces, or influences, or attempts to solicit, induce or influence, any other partner, employee or consultant of Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity to terminate their employment or other business arrangements with Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity, or to engage in any Competing Business or hires, employs, engages (including as a consultant or partner) or otherwise enters into a Competing Business with any such Person;

(B) solicits any of the customers of Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity (or any of their employees), induces such customers or their employees to reduce their volume of business with, terminate their relationship with or otherwise adversely affect their relationship with, Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity;

-70-

(C) does business with any person who was a customer of Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity during the twelve (12) month period prior to such Partner becoming a Terminated or Bankrupt Partner if such business would constitute a Competing Business;

(D) directly or indirectly engages in, represents in any way, or is connected with, any Competing Business, directly competing with the business of Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity, whether such engagement shall be as an officer, director, owner, employee, partner, consultant, affiliate or other participant in any Competing Business; or

(E) assists others in engaging in any Competing Business in the manner described in the foregoing clause (D).

“Competing Business” shall mean an activity that (w) involves the development and operations of electronic trading systems, (x) involves the conduct of the wholesale or institutional brokerage business, (y) consists of marketing, manipulating or distributing financial price information of a type supplied by Cantor, the Partnership or any member of the Cantor Group or Affiliated Entity to information distribution services or (z) competes with any other business conducted by Cantor, the Partnership, any member of the Cantor Group or Affiliated Entity or eSpeed if such business was first engaged in by Cantor, the Partnership, any member of the Cantor Group or Affiliated Entity or eSpeed, or Cantor, the Partnership, any member of the Cantor Group or Affiliated Entity or eSpeed took substantial steps in anticipation of commencing such business and prior to the date on which such Founding/Working Partner or REU Partner, as the case may be, ceases to be a Founding/Working Partner or REU Partner, as the case may be.

(iv) Each payment of the Additional Amounts pursuant to this Section 12.02(h) shall bear interest at the AFR from the Payment Date until paid.

(v) The General Partner may revise the terms of this Section 12.02(c) with respect to any or all Founding/Working Partner Units or REUs, as the case may be; provided, however, that no such amendment may (i) lengthen the term of the Restricted Period or the payout period or (ii) otherwise expand the scope of this Section 12.02(c), unless, in each such case, it is effected by an amendment to this Agreement made pursuant to Section 13.01 or by the terms of another agreement between the Partnership and the holder of the affected Founding/Working Partner Units or REUs, as the case may be. The Partnership and the Partners believe that the provisions of this Section 12.02(c) are reasonable in scope and duration and are necessary to protect the interests of the Partnership and the Affiliated Entities.

-71-

(vi) If any beneficial owner of the stock of a corporate Founding/Working Partner or REU Partner, as the case may be, any partner of any general or limited partnership that is a Founding/Working Partner or an REU Partner, as the case may be, any member of a limited liability company that is a Founding/Working Partner or an REU Partner, as the case may be, or the grantor, trustee or beneficiary of any trust that is a Founding/Working Partner or an REU Partner, as the case may be (such beneficial owner, partner, member, grantor, trustee or beneficiary, a “Competing Owner”), directly or indirectly engages in any Competitive Activity or otherwise breaches a Partner Obligation (or takes action that would constitute a Competitive Activity or other breach of a Partner Obligation if such person were a Founding/Working Partner or REU Partner, as the case may be), the Partnership shall have the right to redeem a number of the Founding/Working Partner Units or REUs, as the case may be, of such Partner equal to the product of the maximum percentage of the ownership of such Partner (by vote or value in the case of a corporation, by profits or capital interest in the case of a partnership or limited liability company or by the greater of the portion of such trust as to which the Competing Owner is a grantor or beneficiary as reasonably determined by the General Partner) held by the Competing Owner at any time during the twelve (12) month period preceding the breach and the number of Founding/Working Partner Units or REUs, as the case may be, held by such entity Partner at the time the Competitive Activity or other breach of a Partner Obligation commences. The foregoing shall apply with such changes as the General Partner deems appropriate to reflect the intent of the foregoing with respect to any Founding/Working Partner or REU Partner, as the case may be, that is an entity not specifically identified above. Anything to the contrary in Section 9.02 notwithstanding, the General Partner shall have the right to redeem such Founding/Working Partner Units or REUs, as the case may be, for a price equal to the Base Amount (which may be $0.00) attributable to such Founding/Working Partner Units or REUs, as the case may be, or, if less, the amount, if any, payable in respect of such Founding/Working Partner Units or REUs, as the case may be, under Section 3.03.

(vii) The General Partner may condition the receipt of any amount payable to a Terminated or Bankrupt Founding/Working Partner or REU Partner, as the case may be, upon the receipt of a certification, in form and substance acceptable to the General Partner, that such former Partner has not engaged in any Competitive Activity or otherwise breached a Partner Obligation. A former Founding/Working Partner or REU Partner, as the case may be, shall be liable for all damages (including any payments of Base Amount or Additional Amounts made as a result of a false certification) resulting from the inaccuracy of any such certification including attorneys’ fees and expenses incurred by the Partnership and shall also be liable for interest at the lesser of nine (9) percentage points above the prime rate as published in the Wall Street Journal, Eastern Edition in effect from time to time or the highest rate permitted by law on the amount of any damages owed to the Partnership.

-72-

(viii) Notwithstanding anything in this Agreement to the contrary, the Personal Representative of a Founding/Working Partner or REU Partner, as the case may be, who has become a Terminated Partner on account of death shall receive payment of his or her Additional Amounts at the same time such Personal Representative receives payment of such deceased Partner’s Base Amount pursuant to Section 4.03; provided, however, that the Personal Representative of a deceased Founding/Working Partner or REU Partner, as the case may be, shall not be entitled to receive payment of such Additional Amounts if such deceased Partner engaged in a Competitive Activity or otherwise breached a Partner Obligation prior to his or her death.

(vi) In no event shall any distribution or payment otherwise payable pursuant to this Section 12.02 be due if and to the extent that the General Partner in its sole and absolute discretion determines in accordance with Section 6.02, that such payment would violate the Act or any other applicable law. If at the time of any payment by the Partnership for Founding/Working Partner Units or REUs, as the case may be, the provision contained in the immediately preceding sentence shall have effect, then the Partnership shall make such payment in the maximum amount that would not violate the Act or any other applicable law, and shall make such further payments, if any, on each 90 day anniversary thereof to the extent that such payments do not violate the Act or any other applicable law, until all obligations for the payment of all amounts due hereunder shall have been paid in full. Any such deferred payments shall bear interest at the AFR.

(v) Each Founding/Working Partner holding Grant Units acknowledges and agrees that payments pursuant to this Section 12.02(f) represent a right to a fixed payment and do not represent a payment with respect to any Partnership asset of any nature.

-86-

is otherwise then due and payable), including, without limitation, any CFLP HDII Account or CFLP HDIII Account. In addition, any Founding Partner that receives shares of BGC Partners Common Stock in connection with an Exchange of an Interest that, following such Exchange, has an outstanding CFLP HDII Account or CFLP HDIII Account shall, following the Exchange, continue to satisfy its payment obligations to Cantor under Section 12.01(b)(ix) (at the times and in the amounts that would have applied had such Interest not have been Exchanged, taking into account amounts paid pursuant to the first sentence of this Section 12.08).

As a condition to any such election, any Founding/Working Partner or REU Partner, as the case may be, electing to become a Terminated Partner pursuant to this Section 13.01(b) must, if requested by the General Partner, provide his or her written consent stating that such Partner agrees that the termination date (or any similar date relating to the cessation of such Partner’s obligations of the Partnership and the Affiliated Entities) of such Founding/Working Partner or REU Partner, as the case may be, under any employment agreement with the Opcos or their Subsidiaries or any Affiliated Entity, shall be accelerated to the effective date of such election, and such electing Founding/Working Partner or REU Partner, as the case may be, shall have no future right to any compensation, benefits, termination payments or other emoluments from the Opcos or their Subsidiaries or an Affiliated Entity, pursuant to any such agreement, and such Founding/Working Partner or REU Partner, as the case may be, shall be entitled to future payments from the Partnership only as provided in this Agreement and as may be determined by the General Partner. The General Partner shall have the right, in the event any Founding/Working Partner or REU Partner, as the case may be, of the Partnership seeks to exercise his, her or its withdrawal rights pursuant to this Section 13.01(b), to revoke and terminate any proposed amendment to this Agreement, in which event all approvals, elections and terminations pursuant hereto shall be of no force and effect, and all agreements shall remain in full force and effect in accordance with their terms prior to the proposed amendments. For this purpose, any proposed amendment of this Agreement subject to this Section 13.01(b) shall not become effective until the later of (A) receipt of sufficient approval by the Partners pursuant to this Section 13.01 or (B) thirty (30) days after written notice to the Partners of the proposed amendment to this Agreement, and shall become effective no later than sixty (60) days after written notice to the Partners of the proposed amendment to this Agreement, unless revoked by the General Partner.

SECTION 13.02. Benefits of Agreement. None of the provisions of this Agreement shall be for the benefit of or enforceable by any creditor of the Partnership or by any creditor of any of the Partners. Except as provided in Article X with respect to Persons entitled to indemnification pursuant to such Article, nothing in this Agreement shall be deemed to create any right in any Person not a party hereto, and this instrument shall not be construed in any respect to be a contract in whole or in part for the benefit of any third person.

SECTION 13.03. Waiver of Notice. Whenever any notice is required to be given to any Partner or other Person under the provisions of the Act or this Agreement, a waiver thereof in writing, signed by the Person or Persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Neither the business to be transacted at, nor the purpose of, any meeting of the Partners (if any shall be called) or the General Partner need be specified in any waiver of notice of such meeting.

SECTION 13.04. Jurisdiction and Forum; Waiver of Jury Trial. (a) Each of the Partners agrees, to the fullest extent permitted by law, that all Actions arising out of or in connection with this Agreement, the Partnership’s affairs, the rights or interests of the Partners or the estate of any deceased Partner (to the extent that they are related to any of the foregoing), or for recognition and enforcement of any judgment arising out of or in connection with this Agreement or any breach or termination or alleged breach or termination of this Agreement, shall be tried and determined exclusively in the state or federal courts in the State of Delaware, and each of the Partners hereby irrevocably submits with regard to any such Action for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Partners hereby expressly waives, to the fullest extent permitted by law, any right it may have to assert, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any such Action: (i) any claim that it is not subject to personal jurisdiction in the aforesaid courts for any reason; (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts; (iii) that (A) any of the aforesaid courts is an inconvenient or inappropriate forum for such Action, (B) venue is not proper in any of the aforesaid courts; and (iv) this Agreement, or the subject matter hereof or thereof, may not be enforced in or by any of the aforesaid courts. With respect to any action arising out of or relating to this agreement or any obligation hereunder, each Partner irrevocably and unconditionally, to the fullest extent permitted by law, (x) agrees to appoint promptly upon request from the Partnership authorized agents for the purpose of receiving service of process in any suit, action or proceeding in Wilmington, Delaware; (y) consents to service of process in any suit, action or proceeding in such jurisdictions; and (z) consents to service of process by mailing a copy thereof to the address of the Partner determined under Section 13.07 by U.S. registered or certified mail, by the closest foreign equivalent of registered or certified mail, by a recognized overnight delivery service, by service upon any agent specified pursuant to clause (x) above, or by any other manner permitted by applicable law.

(b) EACH PARTNER WAIVES ANY RIGHT TO REQUEST OR OBTAIN A TRIAL BY JURY IN ANY JUDICIAL PROCEEDING GOVERNED BY THE TERMS OF THIS AGREEMENT OR PERTAINING TO THE MATTERS GOVERNED BY THIS AGREEMENT. “MATTERS GOVERNED BY THIS AGREEMENT” SHALL INCLUDE, BUT ARE NOT LIMITED TO, ANY AND ALL MATTERS AND AGREEMENTS REFERRED TO IN THIS AGREEMENT AND ANY DISPUTES ARISING WITH RESPECT TO ANY SUCH MATTERS AND AGREEMENTS.

-89-

(c) The Partners acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the Partnership shall be entitled to an injunction or injunctions to prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof and thereof, this being in addition to any other remedy to which they may be entitled by law or equity.

SECTION 13.05. Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto, their respective estates, heirs, legal representatives, successors and permitted assigns, any additional Partner admitted in accordance with the provisions hereof and any successor to a trustee of a trust that is or becomes a party hereto.

SECTION 13.06. Confidentiality. (a) In addition to any other obligations set forth in this Agreement, each Partner recognizes that confidential information has been and will be disclosed to such Partner by the Partnership and its Subsidiaries. Each Partner (other than the Cantor Group and the BGC Partners Group) expressly agrees, whether or not at the time a Partner of the Partnership or providing services to the Partnership and/or any of its Subsidiaries, to (i) maintain the confidentiality of, and not disclose to any Person without the prior written consent of the Partnership, any financial, legal or other advisor to the Partnership, any information relating to the business, clients, affairs or financial structure, position or results of the Partnership or its affiliates (including any Affiliate) or any dispute that shall not be generally known to the public or the securities industry and (ii) not to use such confidential information other than for the purpose of evaluating such Partner’s investment in the Partnership or in connection with the discharge of any duties to the Partnership or an Affiliated Entity such Partner may have in such Partner’s capacity as an officer, director, employee or agent of the Partnership or an Affiliated Entity. Notwithstanding Section 13.04 or any other provision herein to the contrary, each Partner agrees that money damages would not be a sufficient remedy for any breach of this Section 13.06 by such Partner, and that in addition to all other remedies, the Partnership shall be entitled to injunctive or other equitable relief as a remedy for any such breach. Each Partner agrees not to oppose the granting of such relief and agrees to waive any requirement for the securing or posting of any bond in connection with such remedy.

(b) In the event that any third party requests information from a Founding/Working Partner or REU Partner, as the case may be (whether during the period he, she or it is a Partner or during the four-year period following Termination of such Partner), regarding any matter related to such Partner’s employment by the Partnership or any Affiliated Entity or his, her or its role as a Founding/Working Partner or REU Partner, as the case may be, he, she or it will contact and notify the General Counsel of the Partnership before responding to such requests for information, so that the Partnership may take appropriate action to protect its interests. However, neither a Founding/Working Partner nor an REU Partner shall have any obligation to contact and notify the General Counsel of the Partnership prior to any such discussions between such Partner and such Partner’s legal counsel or his certified public accountant.

-90-

(c) In the event that a Founding/Working Partner or an REU Partner is subpoenaed, or asked, to testify as a witness or to produce documents in any legal or administrative or other proceeding related to the Partnership (whether during the period in which he, she or it is a Partner or during the Restricted Period applicable to such Partner), or otherwise required by law to disclose confidential information, he, she or it will promptly notify the Partnership of such subpoena or request and meet with Partnership representatives for a reasonable period of time prior to any such appearance or production.

(d) Each of the current and any former beneficial owners of any corporate or other entity Founding/Working Partner or REU Partner, and each trustee or beneficiary of any trust that is a Founding/Working Partner or REU Partner, shall also be subject to the provisions of this Section 13.06 and each corporate or other entity Founding/Working Partner or REU Partner, as the case may be, and each such trustee or beneficiary agrees to take such action as is requested by the General Partner to ensure the enforcement of this Section 13.06.

(e) Each Founding/Working Partner and each REU Partner agrees to indemnify and hold the Partnership harmless from any loss, cost, damage or claim suffered by the Partnership, including attorneys’ fees and expenses, resulting from a breach by such Partner (including by its beneficial owner or by any trustee of any trust beneficial owner) of this Section 13.06.

SECTION 13.07. Notices. All notices and other communications required or permitted by this Agreement shall be made in writing and any such notice or communication shall be deemed delivered when delivered in Person, properly transmitted by telecopier or one (1) Business Day after it has been sent by an internationally recognized overnight courier to the address for notices shown in the Partnership’s records (or any other address provided to the Partnership in writing for this purpose) or, if given to the Partnership, to the principal place of business of the Partnership in New York, New York. Communications by telecopier also shall be sent concurrently by overnight courier, but shall in any event be effective as stated above. Each Partner may from time to time change its address for notices under this Section 13.07 by giving at least five (5) days’ prior written notice of such changed address to the Partnership.

SECTION 13.08. No Waiver of Rights. No failure or delay on the part of any Partner in the exercise of any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or of any other right or power. The waiver by any Partner of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any other or subsequent breach hereunder. All rights and remedies existing under this Agreement are cumulative and are not exclusive of any rights or remedies otherwise available.

SECTION 13.09. Power of Attorney. Each Partner agrees that, by its execution of this Agreement, such Partner irrevocably constitutes and appoints the General Partner as its true and lawful attorney-in-fact coupled with an interest, with full power and authority, in its

-91-

name, place and stead to make, execute, acknowledge and record (a) all certificates, instruments or documents, including fictitious name or assumed name certificates, as may be required by, or may be appropriate under, the laws of any state or jurisdiction in which the Partnership is doing or intends to do business and (b) all agreements, documents, certificates or other instruments amending this Agreement or the Certificate of Limited Partnership that may be necessary or appropriate to reflect or accomplish (i) a change in the name or location of the principal place of business of the Partnership or a change of name or address of a Partner, (ii) the disposal or increase by a Partner of his Interest in the Partnership or any part thereof, (iii) a distribution and reduction of the capital contribution of a Partner or any other changes in the capital of the Partnership, (iv) the dissolution or termination of the Partnership, (v) the addition or substitution of a Person becoming a Partner of the Partnership and (vi) any amendment to this Agreement, in each case only to the extent expressly authorized and conducted in accordance with the preceding sections of this Agreement. The power granted hereby is coupled with an interest and shall survive the subsequent disability or incapacity of the principal.

SECTION 13.10. Severability. If any one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect under any applicable law, such provision shall be modified to the minimum extent necessary to cause it to be enforceable, and the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired.

SECTION 13.11. Headings. The section and article headings contained in this Agreement are inserted for convenience of reference only and will not affect the meaning or interpretation of this Agreement. All references to Sections or Articles contained herein mean Sections or Articles of this Agreement unless otherwise stated.

SECTION 13.12. Entire Agreement. This Agreement amends and restates in its entirety the Original Limited Partnership Agreement. This Agreement, including the exhibits, annexes and schedules hereto and the Ancillary Agreements, constitute the entire agreement among the parties hereto and supersede all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof and thereof. Notwithstanding anything herein to the contrary, in the event of any conflict or inconsistency between the terms of Article XII and the rest of this Agreement, the terms of the rest of this Agreement shall prevail and Article XII shall be appropriately amended by the General Partner (with the prior written consent of the Exchangeable Limited Partners (by Majority in Interest)) to remove such conflict or inconsistency (without the requirement of any further consent, approval or action of any other Persons).

SECTION 13.13. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflicts of law principles.

SECTION 13.14. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement.

-92-

SECTION 13.15. Opportunity; Fiduciary Duty. To the greatest extent permitted by law and except as otherwise set forth in this Agreement, but notwithstanding any duty otherwise existing at law or in equity:

(a) None of any BGC Partners Company or Cantor Company or any of their respective Representatives shall owe any fiduciary duty to, nor shall any BGC Partners Company or Cantor Company or any of their respective Representatives be liable for breach of fiduciary duty to, the Partnership or the holders of Interests. In taking any action, making any decision or exercising any discretion with respect to the Partnership, each BGC Partners Company and 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 Partnership, the holders of Interests or any other Person, or (ii) to abstain from participating in any vote or other action of the Partnership or any Affiliate thereof, or any board, committee or similar body of any of the foregoing. None of any BGC Partners Company, Cantor Company or any of their respective Representatives shall violate a duty or obligation to the Partnership merely because such Person’s conduct furthers such Person’s own interest, except as specifically set forth in Section 13.15(c). Any BGC Partners Company, Cantor Company or any of their respective Representatives may lend money to, and transact other business with, the Partnership and its Representatives. The rights and obligations of any such Person who lends money to, contracts with, borrows from or transacts business with the Partnership or any of its Representatives are the same as those of a Person who is not involved with the Partnership or any of its Representatives, subject to other applicable law. No transaction between any BGC Partners Company, Cantor Company or any of their respective Representatives, on the one hand, with the Partnership or any of its Representatives, on the other hand, shall be voidable solely because any BGC Partners Company, Cantor Company or any of their respective Representatives has a direct or indirect interest in the transaction. Nothing herein contained shall prevent any BGC Partners Company, 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 BGC Partners Company, 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 Partnership and its Representatives, or (ii) doing business with any of the Partnership’s or its Representatives’ clients or customers. In the event that any BGC Partners Company, Cantor Company or any of their respective Representatives acquires knowledge of a potential transaction or matter that may be a Corporate Opportunity for any BGC Partners Company, Cantor Company or any of their respective Representatives, on the one hand, and the Partnership or its Subsidiaries, on the other hand, such BGC Partners Company, Cantor Company or any of its Subsidiaries, as the case may be, shall have no duty to communicate or offer such Corporate Opportunity to the Partnership or its Representatives. None of any BGC Partners Company, Cantor Company or any of their respective Representatives shall be liable to the Partnership, the holders of

-93-

Interests or its Representatives for breach of any fiduciary duty by reason of the fact that any BGC Partners Company, 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 Partnership or any of its Representatives.

(c) If a third party presents a Corporate Opportunity to a person who is both a Representative of a BGC Partners Company and/or a Cantor Company, expressly and solely in such Person’s capacity as a Representative of the Partnership, and such Person acts in good faith in a manner consistent with the policy that such Corporate Opportunity belongs to the Partnership, then such Person (i) shall be deemed to have fully satisfied and fulfilled any fiduciary duty that such Person has to the Partnership as a Representative of the Partnership with respect to such Corporate Opportunity, (ii) shall not be liable to the Partnership, the holders of Interests 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 Partnership’s best interests, and (iv) shall be deemed not to have breached such Person’s duty of loyalty to the Partnership and the holders of Interests and not have derived an improper personal benefit therefrom; provided that a BGC Partners Company and/or Cantor Company may pursue such Corporate Opportunity if the Partnership 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 Partnership and a Representative of a BGC Partners Company and/or a Cantor Company, expressly and solely in such Person’s capacity as a Representative of the Partnership, such Person shall not be obligated to present such Corporate Opportunity to the Partnership or to act as if such Corporate Opportunity belongs to the Partnership, and such Person shall (A) be deemed to have fully satisfied and fulfilled any fiduciary duty that such Person has to the Partnership as a Representative of the Partnership with respect to such Corporate Opportunity, (B) shall not be liable to the Partnership, any of the holders of Interests 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, (C) 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 Partnership’s best interests, and (iv) shall be deemed not to have breached such Person’s duty of loyalty to the Partnership and the holders of Interests and not have derived an improper personal benefit therefrom.

(d) Any Person purchasing or otherwise acquiring any Interest shall be deemed to have notice of and to have consented to the provisions of this Section 13.15.

(e) Except to the extent otherwise modified herein, each officer of the Partnership shall have fiduciary duties identical to those of officers of business corporations organized under the DGCL. The provisions of this Agreement, to the extent that they restrict or eliminate the duties (including fiduciary duties) of a director, officer or other Person otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties of such Person.

-94-

(f) Neither the alteration, amendment, termination, expiration or repeal of this Section 13.15 nor the adoption of any provision of this Agreement inconsistent with this Section 13.15 shall eliminate or reduce the effect of this Section 13.15 in respect of any matter occurring, or any cause of Action that, but for this Section 13.15, would accrue or arise, prior to such alteration, amendment, termination, expiration, repeal or adoption.

SECTION 13.16. Reimbursement of Expenses. All costs and expenses incurred in connection with the ongoing operation or management of the business of the Partnership or its Subsidiaries shall be borne by the Partnership or its Subsidiaries, as the case may be.

SECTION 13.17. Effectiveness. The Original Limited Partnership Agreement was effective for all financial and accounting purposes as of August 24, 2004. This Agreement shall be effective immediately prior to the Closing (as defined in the Separation Agreement).

SECTION 13.18. Parity of Units. It is the non-binding intention of each of the Partners and the Partnership that the Holdings Ratio shall at all times equal one. Accordingly, in the event of any issuance, or repurchase by U.S. Opco, of U.S. Opco Units to or held by the Partnership, it is the non-binding intention of each of the Partners and the Partnership that there be a parallel issuance or repurchase transaction by the Partnership so that the Holdings Ratio shall at all times equal one, and the parties to this Agreement agree to cooperate to effect the intent of this Section 13.18.

SECTION 13.19. Limitation on Challenge Period and Exclusive Remedies Available to Partners with Respect to any Redemption of Units. (a) Notwithstanding anything in this Agreement or in law or equity to the contrary, no Founding/Working Partner and no REU Partner may institute any action challenging, directly or indirectly, the terms, conditions or validity or any other matter related to or arising out of any redemption by the Partnership of Units held by such Partner, whether such action is based (in whole or in part) in contract, tort and/or any duty otherwise existing in law or equity (a “Challenge”) unless such Challenge is instituted on or prior to the first anniversary (the “Challenge Deadline”) of the later of (i) the effective date of the challenged redemption (the “Effective Date”) and (ii) the giving of notice by the Partnership with respect to such challenged redemption. If a Challenge is not instituted by such Partner on or prior to the Challenge Deadline, such Partner shall be thereafter foreclosed from instituting any Challenge. It shall be a condition to a Partner instituting any Challenge, that (i) such Partner shall have retained the consideration paid to such Partner in the challenged redemption (the “Redemption Consideration”) in the same form as paid by the Partnership and free from any liens or other encumbrances and (ii) such Partner shall make a binding offer to return such consideration to the Partnership on the Final Adjudication Date of any successful Challenge in the same form as paid by the Partnership and free from any liens or other encumbrances.

(b) Notwithstanding anything in this Agreement or in law or equity to the contrary, any such Partner that institutes a Challenge agrees that, in the event such Partner is successful in whole or in part in such Challenge as finally determined in accordance with this Article XIII in a judgment or arbitration award not subject to further appeal (a “Final Adjudication”), the exclusive remedy available to such Partner in such Challenge shall be, as elected by the General Partner in its sole and absolute discretion within 10 days after the date of the Final Adjudication

-95-

(the “Final Adjudication Date”), as follows: either (i) promptly following the Partner’s return to the Partnership of the Redemption Consideration paid in respect of the challenged redemption in accordance with the binding offer referred to in the last sentence of Section 13.19(a), the Partnership shall restore for the account of such Partner all Units held by such Partner redeemed in the challenged redemption and the Adjusted Capital Account related thereto as both existed on the Effective Date immediately prior to the challenged redemption, without regard or entitlement to any statutory interest on the Adjusted Capital Account with respect to such Units between the Effective Date and the date such Units are restored pursuant to this Section 13.19(b)(i), or (ii) promptly following the Partner’s return to the Partnership of the Redemption Consideration paid in respect of the challenged redemption in accordance with the binding offer referred to in the last sentence of Section 13.19(a), the Partnership shall first restore for the account of such Partner all Units held by such Partner redeemed in the challenged redemption and then redeem all of the redeemed Units so restored for the amount of the Adjusted Capital Account attributable to the restored Units as of the Effective Date immediately prior to the challenged redemption, without regard or entitlement to any statutory interest on such Adjusted Capital Account between the Effective Date and the date such Units are restored pursuant to this Section 13.19(b)(ii), such payment to be made at the times, in the amounts and subject to the conditions provided for payments as if the Partner were a Terminated Partner under Article XI in respect of the restored Units so redeemed and subject to all of the other provisions of the Agreement, including, without limitation, Section 3.03. In addition, the Partnership shall pay to the Partner, or the Partner shall pay to the Partnership, as the case may be, without regard or entitlement to any statutory interest, the difference between the amounts of distributions or other payments the Partner received in respect of the challenged Redemption Consideration on and after the Effective Date and the amount of distributions such Partner would have received during such period in respect of his, her or its Units redeemed in the challenged redemption had the challenged redemption not occurred. Any and all returns by a Partner of challenged Redemption Consideration in accordance with the binding offer referred to in the last sentence of Section 13.19(a) shall be made within 20 days of the Final Adjudication Date.

(c) This Section 13.19 shall not limit or restrict any remedies that the Partnership or the General Partner may have under this Agreement, at law or equity, against a Partner that institutes any Challenge to any redemption that is subject to this Section 13.19, and the matters described herein shall be subject to all of the other provisions of the Agreement, including, without limitation, Section 3.03 and Section 2.09(c).
