 W I T N E S S E T H: 

WHEREAS, BGCP, Newmark, Inc. and the other parties thereto have entered into the Separation and Distribution Agreement, dated as of
December 13, 2017 (as amended from time to time, the “Separation and Distribution Agreement”), to effect the Contribution and the Distribution (each as defined in the Separation and Distribution Agreement); and 

WHEREAS, in order to facilitate and provide for an orderly transition under the Separation and Distribution Agreement, the parties desire to
enter into this Agreement to set forth the terms and conditions pursuant to which the parties shall provide Transition Services (as defined herein). 

NOW, THEREFORE, in consideration of the premises contained herein, it is agreed as follows: 

1. Term. 
 (a) The
term of this Agreement shall commence at the Closing (as such term is defined in the Separation and Distribution Agreement) and shall remain in effect until the second anniversary of the Distribution (the “Term”); provided,
however, that in the event that Newmark, Inc. terminates this Agreement, BGC Partners shall be entitled to continued use of any hardware and equipment that it used prior to the date of this Agreement upon the terms and conditions set forth
herein (including, without limitation, the payment terms in Section 5 of this Agreement) until the second anniversary of the Distribution; provided, further, that Newmark shall not be required to repair or replace any such
hardware or equipment. 
 (b) This Agreement may be terminated by a party as provided herein or, as provided in Section 12 of this
Agreement, with respect to a particular service or group of services only, in which case it shall remain in full force and effect with respect to the other services described herein. The terminating party shall pay to the other party an amount equal
to the costs incurred by the Providing Party as a result of such termination, including, without limitation, any severance or cancellation fees. 

 2. Services. 

(a) During the Term, and upon the terms and conditions set forth herein, BGC Partners shall provide to Newmark the Transition Services as
reasonably requested by Newmark, Inc. from time to time, to the extent BGC Partners provided such Transition Services to Newmark prior to the date hereof. 

(b) During the Term, and upon the terms and conditions set forth herein, Newmark shall provide to BGC Partners the Transition Services as BGCP
may reasonably request from time to time, to the extent Newmark provided such Transition Services to BGC Partners prior to the date hereof. 

(c) As used in this Agreement: 

(1) “Transition Services” means the following services, but only to the extent that the Providing Party
provides such services to its own businesses: (i) office space, (ii) personnel, hardware and equipment services, (iii) communication and data facilities and (iv) such other miscellaneous services of a transitional nature as the
parties may reasonably agree. 
 (2) “Providing Party” means the party providing any particular Transition
Service. 
 (3) “Receiving Party” means the party receiving any particular Transition Service. 

(d) Each Providing Party shall use that degree of skill, care and diligence in the performance of Transition Services hereunder that (i) a
reasonable person would use acting in like circumstances in accordance with industry standards and all applicable laws and regulations and (ii) is no less than that exercised by such Providing Party with respect to such Transition Services that
it performs with respect to its own businesses. 
 (e) The applicable Providing Party and Receiving Party shall cooperate with each other in
all reasonable respects in matters relating to the provision and receipt of the Transition Services. Such cooperation shall include obtaining all consents, licenses or approvals necessary to permit each party to perform its obligations hereunder.

 (f) In the event the Receiving Party uses assets that are subject to an operating lease between the Providing Party and a third party to
provide services hereunder, the Receiving Party shall comply with the terms and conditions of such operating lease. 
 3. Intellectual
Property. 
 (a) No Intellectual Property (as such term is defined in the Separation and Distribution Agreement) that is owned or
licensed by a Providing Party shall transfer to a Receiving Party as a result of this Agreement or the provision of Transition Services hereunder. 

  
 -2- 

 (b) Any Intellectual Property owned by a Providing Party or third-party licensors or service
providers that may be operated or used by a Providing Party in connection with the provision of the Transition Services hereunder will remain the property of the Providing Party or third-party licensors or service providers, and the Receiving Party
shall have no rights or interests therein, except as may otherwise be expressly provided in any separate agreement. 
 4.
Authority. Notwithstanding anything to the contrary contained in Section 2 of this Agreement, the parties hereto acknowledge and agree that each Providing Party shall provide the Transition Services as set forth in Section 2
of this Agreement, subject to the ultimate authority of the Receiving Party to control its own business and affairs. Each party acknowledges that the services provided hereunder by any Providing Party are intended to be administrative, technical and
ministerial and are not intended to set policy for the Receiving Party. 
 5. Charges for Services. 

(a) In consideration for providing the Transition Services provided for in Section 2 of this Agreement (other than office space, which
shall be governed by Section 5(b) of this Agreement), each Receiving Party shall pay to the Providing Party an amount equal to (i) the direct cost that the Providing Party incurs in performing such Transition Services plus (ii) a
reasonable allocation of other allocated costs, including, without limitation, depreciation and amortization determined in a consistent and fair manner so as to cover such Providing Party’s appropriate costs or in such other manner as the
parties shall agree. The Providing Party shall not charge the Receiving Party any portion of any tax for which the Providing Party receives a rebate or credit, or to which the Providing Party is entitled to a rebate or credit. 

(b) To the extent that BGC Partners provides office space hereunder, such office space shall be invoiced to and paid by Newmark as follows:

 So long as Newmark uses any portion of BGC Partners’ offices (each, a “BGC Partners Office”), Newmark shall pay to
BGC Partners on the first day of each calendar month with respect to each such BGC Partners Office an amount equal to the product of (x) the average rate per square foot then being paid by BGC Partners for such BGC Partners Office and
(y) the number of square feet requested by Newmark and made available for use by Newmark. In addition, Newmark shall pay to BGC Partners on the first day of each calendar month an amount equal to the sum of the costs allocated under U.S.
generally accepted accounting principles, including, without limitation, leasehold amortization expenses, depreciation, overhead, taxes and repairs in relation to such BGC Partners Office for the preceding month multiplied by a fraction, the
numerator of which equals the number of square feet requested by Newmark and made available for use by Newmark and the denominator of which equals the total number of square feet leased by BGC Partners under the lease for the applicable BGC Partners
Office.

 6. Exculpation and Indemnity; Other Interests. 

(a) BGC Partners (including, without limitation, its stockholders, managers, members, partners, officers, directors and employees) shall not be
liable to Newmark or the equityholders of Newmark for any acts or omissions taken or not taken in good faith on behalf of Newmark and in a manner reasonably believed by BGCP to be within the scope of the authority granted to it by this Agreement and
in the best interests of Newmark, except for acts or omissions constituting fraud or willful misconduct in the performance of BGCP’s duties under this Agreement. Notwithstanding the foregoing, BGC Partners shall be liable to Newmark for any
losses incurred by Newmark in connection with the provision of Transition Services by BGC Partners hereunder to the extent BGC Partners is entitled to be reimbursed by an unaffiliated third party for any such liability. Newmark shall indemnify,
defend and hold harmless BGC Partners (and its stockholders, managers, members, partners, officers, directors and employees) from and against any and all claims or liabilities of any nature whatsoever (including, without limitation, consequential
damages and reasonable attorney’s fees) arising out of or in connection with any claim against BGC Partners with respect to its provision of Transition Services hereunder, except where attributable to the fraud or willful misconduct of BGC
Partners. 
 (b) Newmark (including, without limitation, its stockholders, managers, members, partners, officers, directors and employees)
shall not be liable to BGC Partners or the equityholders of BGC Partners for any acts or omissions taken or not taken in good faith on behalf of BGC Partners and in a manner reasonably believed by Newmark, Inc. to be within the scope of the
authority granted to it by this Agreement and in the best interests of BGC Partners, except for acts or omissions constituting fraud or willful misconduct in the performance of Newmark, Inc.’s duties under this Agreement. Notwithstanding the
foregoing, Newmark shall be liable to BGC Partners for any losses incurred by BGC Partners in connection with the provision of Transition Services by Newmark hereunder to the extent Newmark is entitled to be reimbursed by an unaffiliated third party
for any such liability. BGC Partners shall indemnify, defend and hold harmless Newmark (and its stockholders, managers, members, partners, officers, directors and employees) from and against any and all claims or liabilities of any nature whatsoever
(including, without limitation, consequential damages and reasonable attorney’s fees) arising out of or in connection with any claim against Newmark with respect to its provision of Transition Services hereunder, except where attributable to
the fraud or willful misconduct of Newmark. 
 (c) Nothing in this Agreement shall prevent BGC Partners and its affiliates from engaging in
or possessing an interest in other business ventures of any nature or description, independently or with others, whether currently existing or hereafter created, and none of Newmark or any of its stockholders shall have any rights in or to such
independent ventures or to the income or profits derived therefrom as a result of this Agreement. 
 7. Relationship of the
Parties. 
 (a) The relationship of each Providing Party and each Receiving Party shall be that of contracting parties, and no
partnership, joint venture or other arrangement shall be deemed to be created by this Agreement. 

  
 -4- 

 (b) Except as expressly provided herein, neither BGC Partners nor Newmark shall have any claim
against the other or right of contribution by virtue of this Agreement with respect to any uninsured loss incurred by any of them nor shall any of them have a claim or right against the other by virtue of this Agreement with respect to any loss that
is deemed to be included within the deductible, retention or self-insured portion of any insured risk. 

8. Audit. Any party hereto may request a review, by those certified public accountants who examine BGC Partners’ or
Newmark’s books and records, of the other party’s cost allocation to the requesting party to determine whether such allocation is proper under the procedures set forth herein. Such a review is to be conducted at the requesting party’s
expense unless such allocation is determined not to be proper, in which case such review shall be at the other party’s expense. 

9. Documentation. Each party’s charges to the other for all Transition Services hereunder shall be substantiated by
appropriate schedules, invoices or other documentation. During the Term, each Providing Party shall use commercially reasonable efforts to maintain records relating to the Transition Services being provided in a manner similar to record maintenance
with respect to other administrative services previously provided by such Providing Party, including, without limitation, data relating to the determination of charges payable by the Receiving Party of such Transition Services, and otherwise in
accordance with the record management practices and with at least the same degree of care and completeness as applicable to such Providing Party at such time. 

10. Actual Cost. Any charges to the Receiving Party for Transition Services provided by BGC Partners or Newmark, as the
case may be, or by third parties pursuant to Section 2 of this Agreement shall be based upon rates intended to reflect the Providing Party’s actual cost of providing such Transition Services and not to provide a profit to BGC Partners or
Newmark, as applicable. Any sales, use, value added, turnover or similar taxes required to be charged in respect of Transition Services provided by a party to another party shall be charged in addition to any charges otherwise due hereunder, and
shall be included in the relevant invoice. 
 11. Invoicing and Billing. Each party shall invoice the other for
charges for Transition Services provided pursuant hereto on a monthly basis as incurred, such invoices to be delivered to the other party within 15 days after the end of each calendar month. Such invoices may include third party charges
incurred in providing Transition Services pursuant to Section 2 of this Agreement or, at the invoicing party’s option, Transition Services provided by one or more third parties may be invoiced directly to the Receiving Party of those
Transition Services. Each Receiving Party shall pay to the relevant Providing Party the aggregate charge for Transition Services provided under this Agreement in arrears, subject to receipt of an invoice from the Providing Party in accordance with
this Section 11, within 30 days after the end of each calendar month. Amounts due by one party to the other party under this Agreement shall be netted against amounts due by the other party to the first party under this Agreement or any
other agreement. 
 12. Services by Third Parties or Affiliates. Either party may, without cause, procure any of
the Transition Services specified in Section 2 of this Agreement from a third party or may provide such Transition Services directly or through an affiliate. The Providing Party  

  
 -5- 

 
shall discontinue providing any Transition Service to the Receiving Party upon written notice by the Receiving Party, delivered at least 90 days before the requested termination date. The
Receiving Party shall pay to the Providing Party an amount equal to the costs incurred by the Providing Party as a result of such termination, including, without limitation, any severance or cancellation fees. 

13. Failure to Perform the Transition Services. In the event of any breach of this Agreement by the Providing Party with
respect to any error or defect in providing any Transition Service, the Providing Party shall, at the Receiving Party’s request, without the payment of any further fees by the Receiving Party, use its commercially reasonable best efforts to
correct or cause to be corrected such error or defect or reperform or cause to be reperformed such Transition Service, as promptly as practicable. 

14. Excused Performance. Neither party warrants that any of the Transition Services agreed to be provided shall be free of
interruption caused by acts of God, strikes, lockouts, accidents, inability to obtain third-party cooperation or other causes beyond its control. No such interruption of Transition Services shall be deemed to constitute a breach of any kind
whatsoever hereunder. 
 15. Survival of Payment Obligations. Notwithstanding any provision herein to the
contrary, all payment obligations hereof shall survive the happening of any event causing termination of this Agreement until all amounts due hereunder have been paid. 

16. Confidentiality. Except as otherwise provided in this Agreement, (a) the Providing Party shall, and shall cause
its affiliates (and their respective accountants, counsel, consultants, employees and agents to whom they disclose such information), to keep confidential all information in the possession of the Providing Party that in any way relates to the
Receiving Party and is received in connection with the provision of Transition Services hereunder, and (b) the Receiving Party shall, and shall cause its affiliates (and their respective accountants, counsel, consultants, employees and agents
to whom they disclose such information), to keep confidential all information in possession of the Receiving Party that relates to the Providing Party, is not information related to the Receiving Party and that is received in connection with the
receipt of Transition Services hereunder. The provisions of this Section 16 do not apply to the disclosure by either party or their respective affiliates (and their respective accountants, counsel, consultants, employees and agents to whom they
disclose such information) of any information (i) which is, or becomes, publicly available, other than by reason of a breach of this Section 16 by the disclosing party or any affiliate of the disclosing party, (ii) received from a
third party not bound by any confidentiality agreement with the other party, (iii) required by applicable law to be disclosed by that party, or (iv) necessary to establish such party’s rights under this Agreement or the Separation and
Distribution Agreement or other agreements executed in connection herewith or therewith, provided that in the case of clauses (iii) and (iv), the person intending to make disclosure of confidential information will promptly notify the party to
whom it is obligated to keep such information confidential and, to the extent practicable, provide such party a reasonable opportunity to prevent public disclosure of such information. 

  
 -6- 

 Upon the request of a Receiving Party and upon termination of the relevant Transition Service
and/or this Agreement, each Providing Party shall provide the Receiving Party with any data or information generated with respect to the terminated Transition Service(s) provided to the Receiving Party in a format usable by the Receiving Party. The
Receiving Party shall pay the cost, if any, of converting such data or information into the appropriate format. 
 17.
Miscellaneous.

respective successors, assigns and transferees, including binding upon any person that will be a successor to a party hereto, whether by merger, consolidation or sale of all or substantially all of its assets. This Agreement and any rights or

Periods. For purposes of this Agreement, with respect to any Joint Income Tax Return for any Post-2016 Period that ends on or before the Deconsolidation Date, Income Taxes that are attributable to the Newmark Business shall be the hypothetical
stand-alone Tax Liability of the Newmark Group (and/or any of its members) for such Tax Period with respect to a pro forma Tax Return of members of the Newmark Group that takes into account only the relevant operations, assets and liabilities (and

on the following basis, as determined by BGC Partners in its sole good faith discretion:

Divisions and the Contribution) shall be assumed to have occurred immediately before January 1, 2017, such that all of the operations, assets and liabilities of the Newmark Business held by members of the Newmark Group as of immediately before

or before the Deconsolidation Date, and treating all such Tax Attributes as being subject to the limitations under applicable Tax Law (including limitations on carrybacks and carryforwards) that would apply if the relevant members of the Newmark
Group had filed Tax Returns on the basis set forth in this Section 3.02 for all Tax Periods (or portions thereof) relevant to the computation; provided, that the Newmark Group and/or its members shall be deemed to have
relinquished, waived or otherwise foregone any carrybacks to any taxable period (or portion thereof) beginning prior to January 1, 2017, and if any such Tax Attribute would, under applicable Tax Law be required to be carried back to such a
period (or portion thereof), such Tax Attribute shall be deemed to be available to the Newmark Group on a carryforward basis (subject to the limitations under applicable Tax Law on such carryforwards). For the avoidance of doubt, for purposes of
calculating any available carryforward or carryback of Tax Attributes pursuant to this clause (d), the utilization of any such Tax Attributes by members of the BGC Group shall be disregarded;

member of the BGC Group Actually Realizes a Tax Benefit as a result of the utilization of such Tax Attribute, as determined by BGC Partners in its sole good faith discretion (any Refund to the Newmark Group (and/or any of its members) determined

year that includes the Deconsolidation, no election shall be made under Treasury Regulation Section 1.1502-76(b)(2)(ii). If the Deconsolidation Date is not an Accounting Cutoff Date, the provisions of

prior to the Deconsolidation Date) be allocated to Pre-Deconsolidation Periods, and any Taxes related to such items shall be treated under Treasury Regulation Section 1.1502-76(b)(2)(iv) as relating to
such extraordinary item and shall (to the extent occurring on or prior to the Deconsolidation Date) be allocated to Pre-Deconsolidation Periods. To the extent relevant for purposes of this Agreement, similar principles shall apply for purposes of

amount of any Distribution Tax-Related Losses described in clause (ii) or (iii) of the definition of Tax-Related Losses for which BGC Partners is responsible under this 

  
 35 

 
Section 7.05 no later than two (2) Business Days after the date Newmark pays such Distribution Tax-Related Losses. Each Company shall have the right to review the calculation of
Distribution Tax-Related Losses prepared by the other Company, including any related workpapers and other supporting documentation. 

Section 7.06 Section 336(e) Election. If BGC Partners determines, in its sole discretion, that a protective election under
Section 336(e) of the Code (a “Section 336(e) Election”) shall be made with respect to the Distribution, Newmark shall (and shall cause the relevant member of the Newmark Group to) join with BGC Partners or the relevant
member of the BGC Group in the making of such election and shall take any action reasonably requested by BGC Partners or that is otherwise necessary to give effect to such election (including making any other related election). If a
Section 336(e) Election is made with respect to the Distribution, then this Agreement shall be amended in such a manner as is determined by BGC Partners in good faith to take into account such Section 336(e) Election (including by
requiring that, in the event the Contribution and Distribution fail to have Tax-Free Status and BGC Partners is not entitled to indemnification for the Distribution Tax-Related Losses arising from such failure, Newmark shall pay over to BGC Partners
any Tax Benefits Actually Realized by the Newmark Group or any member of the Newmark Group arising from the step-up in Tax basis resulting from the Section 336(e) Election). 

Section 8. Assistance and Cooperation. 

Section 8.01 Assistance and Cooperation. 

(a) Each of the Companies shall provide (and cause its Affiliates to provide) the other and its agents, including accounting firms and legal
counsel, with such cooperation or information as such other Company reasonably requests in connection with (i) preparing and filing Tax Returns, (ii) determining the liability for and amount of any Taxes due (including estimated Taxes) or
the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Taxes assessed or proposed to be assessed. Such cooperation shall include making available,
upon reasonable notice, all information and documents in their possession relating to the other Company and its Affiliates as provided in Section 9. Each of the Companies shall also make available to the other, as reasonably requested
and available, personnel (including employees and agents of the Companies or their respective Affiliates) responsible for preparing, maintaining, and interpreting information and documents relevant to Taxes. 

(b) Any information or documents provided under this Section 8 or Section 9 shall be kept confidential by the Company
receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. Notwithstanding any other provision of this
Agreement or any other agreement, in no event shall either of the Companies or any of its respective Affiliates be required to provide the other Company or any of its respective Affiliates or any other Person access to or copies of any information
if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that either Company determines that the provision of any information to the other Company or its Affiliates could be commercially
detrimental, violate any Law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with their obligations under this Section 8 or Section 9 in a manner that avoids any such
harm or consequence. 

  
 36 

 Section 8.02 Income Tax Return Information. Newmark and BGC Partners
acknowledge that time is of the essence in relation to any request for information, assistance or cooperation made by BGC Partners or Newmark pursuant to Section 8.01 or this Section 8.02. Newmark and BGC Partners acknowledge
that failure to conform to the deadlines set forth herein or reasonable deadlines otherwise set by BGC Partners or Newmark could cause irreparable harm. Each Company shall provide to the other Company information and documents relating to its Group
required by the other Company to prepare Tax Returns. Any information or documents the Responsible Company requires to prepare such Tax Returns shall be provided in such form as the Responsible Company reasonably requests and in sufficient time for
the Responsible Company to file such Tax Returns on a timely basis. 
 Section 8.03 Reliance by BGC Partners. If any
member of the Newmark Group supplies information to a member of the BGC Group in connection with a Tax liability and an officer of a member of the BGC Group signs a statement or other document under penalties of perjury in reliance upon the accuracy
of such information, then upon the written request of such member of the BGC Group identifying the information being so relied upon, the Chief Financial Officer of Newmark (or any officer of Newmark as designated by the Chief Financial Officer of
Newmark) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. Newmark agrees to indemnify and hold harmless each member of the BGC Group and
its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the Newmark Group having supplied, pursuant to this Section 8, a member of the BGC Group with
inaccurate or incomplete information in connection with a Tax liability. 
 Section 8.04 Reliance by Newmark. If any
member of the BGC Group supplies information to a member of the Newmark Group in connection with a Tax liability and an officer of a member of the Newmark Group signs a statement or other document under penalties of perjury in reliance upon the
accuracy of such information, then upon the written request of such member of the Newmark Group identifying the information being so relied upon, the Chief Financial Officer of BGC Partners (or any officer of BGC Partners as designated by the Chief
Financial Officer of BGC Partners) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. BGC Partners agrees to indemnify and hold harmless
each member of the Newmark Group and its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the BGC Group having supplied, pursuant to this Section 8, a
member of the Newmark Group with inaccurate or incomplete information in connection with a Tax liability. 
 Section 9. Tax
Records. 
 Section 9.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records in its
possession relating to the assets and activities of the Group for Pre-Deconsolidation Periods or Taxes or Tax matters that are the subject of this Agreement, in each case, for so long as the contents thereof may become material in the administration
of any matter 

  
 37 

 
under the Code or other applicable Tax Law, but in any event until the later of (i) the expiration of any applicable statutes of limitations, or (ii) eight years after the
Deconsolidation Date (such later date, the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records upon 90 days’ prior written notice to the other Company. If, prior to the Retention Date, a
Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 9 are no longer material in the administration of any matter under the Code or other applicable Tax Law and
the other Company agrees, then such first Company may dispose of such Tax Records upon 90 days’ prior notice to the other Company. Any notice of an intent to dispose given pursuant to this Section 9.01 shall include a list of the
Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 90-day period, all
or any part of such Tax Records. 
 Section 9.02 Access to Tax Records. The Companies and their respective Affiliates shall make
available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records to the extent reasonably required by the other Company in connection with the preparation of financial accounting statements,
audits, litigation, or the resolution of items under this Agreement. 
 Section 10. Tax Contests. 

Section 10.01 Notice. 

(a) In General. Each of the Companies shall provide prompt notice to the other Company of any written communication from a Tax Authority
regarding any pending or threatened Tax audit, assessment or proceeding or other Tax Contest relating to Taxes, Refunds or Tax Benefits for which it may be entitled to indemnification by the other Company hereunder. Such notice shall include copies
of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail. The failure of one Company to notify the other of such
communication in accordance with the immediately preceding sentences shall not relieve such other Company of any liability or obligation to pay such Tax or make indemnification payments under this Agreement, except to the extent that the failure
timely to provide such notification actually prejudices the ability of such other Company to contest such Tax liability or increases the amount of such Tax liability. 

(b) Newmark Change Notices. If any member of the Newmark Group receives a Change Notice described in Section 4.01 of the BGC
Partners TRA, Newmark shall promptly notify BGC Partners of such Change Notice in such manner as would allow BGC Partners to comply with its obligations under Section 4.01 of the BGC Partners TRA. Newmark shall (and shall cause its Affiliates
to) cooperate with BGC Partners and take any such actions as may be necessary to permit BGC Partners to comply with its obligations under Section 7.01 of the BGC Partners TRA. 

  
 38

(5) Newmark shall defend such Tax Contest diligently and in good faith as if it were the only party in interest in connection with such Tax Contest, (6) BGC Partners shall be entitled to participate in such Tax Contest, and
(7) Newmark shall not settle, compromise or abandon any such Tax Contest without obtaining the prior written consent of BGC Partners, which consent shall not be unreasonably withheld, conditioned or delayed. 

  
 39 

 (e) Distribution-Related Tax Contests. BGC Partners shall have exclusive control over any
Distribution-Related Tax Contest, including exclusive authority with respect to any settlement of such Tax Contest, subject to the following provisions of this Section 10.02(e). In the event of any Distribution-Related Tax Contest as a
result of which Newmark could reasonably be expected to become liable for any Distribution Tax-Related Losses, (1) BGC Partners shall keep Newmark reasonably informed in a timely manner of all significant developments in respect of such Tax

settlement or other disposition, in any Distribution-Related Tax Contest shall be made in the sole discretion of BGC Partners and shall be final and not subject to the dispute resolution provisions of Section 14 of this Agreement or
Section 8.07 (Direct Claims) of the Separation and Distribution Agreement. 
 (f) Power of Attorney. Each member of the Newmark
Group shall execute and deliver to BGC Partners (or such member of the BGC Group as BGC Partners shall designate) any power of attorney or other similar document reasonably requested by BGC Partners (or such designee) in connection with any Tax
Contest controlled by BGC Partners described in this Section 10. Each member of the BGC Group shall execute and deliver to Newmark (or such member of the Newmark Group as Newmark shall designate) any power of attorney or other similar
document reasonably requested by Newmark (or such designee) in connection with any Tax Contest controlled by Newmark described in this Section 10. 

Section 11. Effective Date; Termination of Prior Intercompany Tax Allocation Agreements. This Agreement shall be
effective as of the Effective Time. As of the Effective Time, (i) all prior intercompany Tax allocation agreements or arrangements solely between or among BGC Partners and/or any of its Subsidiaries shall be terminated, and (ii) amounts
due under such agreements as of the date on which the Effective Time occurs shall be settled. Upon such termination and settlement, no further payments by or to the BGC Group, or by or to the Newmark Group, with respect to such agreements shall be
made, and all other rights and obligations resulting from such agreements between the Companies and their Affiliates shall cease at such time. Any payments pursuant to such agreements shall be disregarded for purposes of computing amounts due under
this Agreement; provided, that to the extent appropriate, as determined by BGC Partners, payments made pursuant to such agreements shall be credited to the Newmark Entities or the BGC Entities, respectively, in computing their respective obligations
pursuant to this Agreement, in the event that such payments relate to a Tax liability that is the subject matter of this Agreement for a Tax Period that is the subject matter of this Agreement. 

  
 40 

 Section 12. Survival of Obligations. The representations, warranties, covenants and
agreements set forth in this Agreement shall be unconditional and absolute and shall remain in effect without limitation as to time. 

Section 13. Treatment of Payments; Tax Gross Up. 

Section 13.01 Treatment of Tax Indemnity Payments. In the absence of any change in Tax treatment under the Code or other
applicable Tax Law, for all Income Tax purposes, the Companies agree to treat, and to cause their respective Affiliates to treat, (a) any indemnity payment required by this Agreement as, as applicable, (i) a distribution by BGC U.S. Opco
to its partners pursuant to the Opco Partnership Distribution, followed by a contribution by such partners to Newmark Opco pursuant to the Opco Partnership Contribution, (ii) a contribution by BGC Holdings to Newmark Holdings, (iii) a
contribution by BGC Partners to Newmark, (iv) a distribution by Newmark Opco to the partners of BGC U.S. Opco, followed by a contribution by such partners to BGC U.S. Opco, (v) a distribution by Newmark Holdings to BGC Holdings,
(vi) a distribution by Newmark to BGC Partners, as the case may be, in each case to the extent such payment is made after the Opco Partnership Contribution, the Holdings Partnership Distribution or the Distribution, as applicable, and such
payment shall be treated as occurring immediately prior to the Opco Partnership Contribution, the Holdings Partnership Distribution or the Distribution, as applicable, or (vii) a payment of an assumed or retained liability; and (b) any
payment of interest as taxable or deductible, as the case may be, to the party entitled under this Agreement to retain such payment or required under this Agreement to make such payment. 

Section 13.02 Tax Gross Up. If notwithstanding the manner in which payments described in Section 13.01(a) of this
Agreement or Section 6.16 (Treatment of Payments for Tax Purposes) of the Separation and Distribution Agreement were reported, there is an adjustment to the Tax liability of a Company or a member of its Group as a result of its receipt of a
payment pursuant to this Agreement or the Separation and Distribution Agreement, such payment shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all Income Taxes payable with respect to the receipt thereof
(but taking into account all correlative Tax Benefits resulting from the payment of such Income Taxes), shall equal the amount of the payment which the Company receiving such payment would otherwise be entitled to receive. 

Section 13.03 Interest. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”)
makes a payment of interest to another Company (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to the date that the Indemnitor reimbursed the
Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in income to the extent provided by law).
The amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee. 

  
 41 

 Section 14. Disagreements. The Companies desire that collaboration will continue
between them. Accordingly, they will try, and they will cause their respective Group members to try, to resolve in good faith all disagreements regarding their respective rights and obligations under this Agreement, including any amendments hereto.
In furtherance thereof, in the event of any dispute or disagreement (other than a High-Level Dispute) (a “Tax Advisor Dispute”) between any member of the BGC Group and any member of the Newmark Group as to the interpretation of any
provision of this Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve such Tax Advisor Dispute. If such good faith negotiations do not resolve such Tax Advisor Dispute,
then the matter will be referred to a Tax Advisor acceptable to each of BGC Partners and Newmark. The Tax Advisor may, in its discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems
necessary to assist it in resolving such disagreement. The Tax Advisor shall furnish written notice to BGC Partners and Newmark of its resolution of any such Tax Advisor Dispute as soon as practical, but in any event no later than forty-five
(45) days after its acceptance of the matter for resolution. Any such resolution by the Tax Advisor will be conclusive and binding on the Companies. Following receipt of the Tax Advisor’s written notice to the Companies of its resolution
of the Tax Advisor Dispute, the Companies shall each take or cause to be taken any action necessary to implement such resolution of the Tax Advisor. In accordance with Section 15 (and except as provided in the immediately following
sentence), each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor. All fees and expenses of the Tax Advisor in connection
with such referral shall be shared equally by the Companies. Any High-Level Dispute shall be resolved pursuant to the procedures set forth in Section 8.07 (Direct Claims) of the Separation and Distribution Agreement. Nothing in this
Section 14 will prevent either Company from seeking injunctive relief if any delay resulting from the efforts to resolve the Tax Advisor Dispute through the Tax Advisor or any delay resulting from the efforts to resolve any High-Level
Dispute through the procedures set forth in Section 8.07 (Direct Claims) of the Separation and Distribution Agreement could result in serious and irreparable injury to either Company. Notwithstanding anything to the contrary in this Agreement,
the Separation and Distribution Agreement or any Ancillary Agreement, each of BGC Partners and Newmark is the only member of its respective Group entitled to commence a dispute resolution procedure under this Agreement, and each of BGC Partners and
Newmark will cause its respective Group members not to commence any dispute resolution procedure other than through such party as provided in this Section 14. 

Section 15. Expenses. Except as otherwise provided in this Agreement, each party and its Affiliates shall bear their own
expenses incurred in connection with the preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement. 

Section 16. General Provisions. 

Section 16.01 Entire Agreement. This Agreement, together with the Separation and Distribution Agreement, shall constitute the
entire agreement among the parties hereto with respect to the subject matter hereof and shall supersede all previous negotiations, commitments and writings with respect to such subject matter. In the event of any inconsistency between this Agreement
and the Separation and Distribution Agreement, or any other agreements relating to the transactions contemplated by the Separation and Distribution Agreement, with respect to matters addressed herein, the provisions of this Agreement shall control.

  
 42

and shall not affect in any way the meaning or interpretation of this Agreement.

Agreement. 
 Section 16.06 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument.

without regard to the conflicts-of-law principles of such State. 
 (b) Each of the Companies irrevocably and unconditionally submits to the

of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby (and agrees that no such action, suit or proceeding relating to this Agreement shall be brought by it or any member of its Group except in
such courts). Each of the Companies further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in
Section 16.02 shall be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of
the Companies irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement in the Delaware Court of Chancery (and if the Delaware Court
of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such action, suit or proceeding brought in any such court has been brought in an
inconvenient forum.

supplemented only by a written agreement signed by all of the Companies.

Newmark acquires or creates one or more subsidiaries that are includable in the Newmark Group, they shall be subject to this Agreement and all references to the Newmark Group herein shall thereafter include a reference to such subsidiaries. 

Section 16.10 Successors. This Agreement shall be binding upon and inure to the benefit of any successor by merger, consolidation,
sale of all or substantially all assets, or otherwise, to any of the parties hereto (including but not limited to any successor of BGC Partners or Newmark succeeding to the Tax Attributes of either under Section 381 of the Code), to the same
extent as if such successor had been an original party to this Agreement. 
 Section 16.11 Injunctions. The parties acknowledge
that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. The parties hereto shall be entitled to an injunction or injunctions
