Article II 
 Demand
Registrations 
 Section 2.1 Requests for Registration. Subject to the provisions of this Article II, any Holder or group of
Holders may at any time make a written request (a “Demand Request”) for registration under the Securities Act of Registrable Securities (a “Demand Registration”). Such Demand Requests shall specify the amount of
Registrable Securities to be registered and the intended method or methods of disposition. Newmark shall, subject to the provisions of this Article II and to the Holders’ compliance with their obligations under the provisions of this Agreement,
use its reasonable best efforts to file with the SEC a Registration Statement registering all Registrable Securities included in such Demand Request, for disposition in accordance with the intended method or methods set forth therein;
provided that if the managing underwriter(s) for a Demand Registration in which Registrable Securities are proposed to be included pursuant to this Article II that involves an underwritten offering shall advise Newmark that, in its reasonable
opinion, the number of Registrable Securities to be sold is greater than the amount that can be offered without adversely affecting the success of the offering (taking into consideration the interests of Newmark and the Holders), then Newmark will
be entitled to reduce the number of Registrable Securities included in such registration to the number that, in the opinion of the managing underwriter(s), can be sold without having the adverse effect referred to above; provided,
further, that in the event of such a reduction in the number of Registrable Securities included in such registration, the number of Registrable Securities registered shall be allocated in the following priority: first, pro rata among
the Holders participating in the Demand Registration, based on the number of Registrable Securities included by such Holder in the Demand Request; second, shares of Newmark Class A Common Stock proposed to be registered for offer and
sale by Newmark; and third, shares of Newmark Class A Common Stock proposed to be registered pursuant to any piggy-back registration rights of security holders of Newmark other than any Holder. Newmark shall use its reasonable best
efforts to cause such Registration Statement to be declared effective as soon as practicable after filing and to remain effective until the earlier of (i) 90 days following the date on which it was declared effective and (ii) the date on which
all of the Registrable Securities covered thereby are disposed of in accordance with the method or methods of disposition stated therein. 

Section 2.2 Timing of Registrations. Notwithstanding anything in this Article II to the contrary, Newmark shall not be obligated
to effect a Demand Registration (i) if a Piggy-back Registration had been available to any Holder within the 180 days preceding the date of the Demand Request or (ii) during any period (not to exceed 180 days) following the closing of the
completion of an offering of securities by Newmark if such Demand Registration would cause Newmark to breach a “lock-up” or similar provision contained in the underwriting agreement for such
offering. 

  
 -5- 








 Section 2.3 Suspension of Registration. Notwithstanding the foregoing, if in the good
faith judgment of the Board of Directors of Newmark it would be materially detrimental to Newmark and its stockholders for any Registration Statement to be filed or continued to be used or for any Registration Statement or Prospectus to be amended
or supplemented because such filing, continued use, amendment or supplement would (i) require disclosure of material non-public information, the disclosure of which would be reasonably likely to
materially and adversely affect Newmark and its subsidiaries taken as a whole, or (ii) materially interfere with any existing or prospective business transaction or negotiation involving Newmark, Newmark shall have the right to suspend the use
of the applicable Registration Statement or delay delivery or filing, but not the preparation, of the applicable Registration Statement or Prospectus or any document incorporated therein by reference, in each case for a reasonable period of time;
provided, however, that Newmark shall not be able to exercise such suspension right more than twice in each 12-month period aggregating not more than 150 days in such 12-month period. In the event that the ability of the Holders to sell shall be suspended for any reason, the period of such suspension shall not count towards compliance with the
90-day period referred to in clause (i) of Section 2.1. 
 Article III 

Piggy-back Registrations 

Section 3.1 Right to Include Registrable Securities. If at any time Newmark proposes to register (including for this purpose a
registration effected by Newmark for security holders of Newmark other than any Holder) securities which may include any shares of Newmark Common Stock and to file a Registration Statement with respect thereto under the Securities Act, whether or
not for sale for its own account (other than pursuant to (i) a registration statement on Form S-4, Form S-8 or any successor or similar forms; or (ii) a
registration statement for the sales of Registrable Securities issuable or issued upon exchange, conversion or sale of any Newmark Holdings Exchangeable Limited Partnership Interests held by any member of the Cantor Group), in a manner that would
permit registration of Registrable Securities for resale to the public under the Securities Act (a “Public Offering”), Newmark will each such time promptly give written notice to the Holders of (a) its intention to do so,
(b) the form of registration statement of the SEC that has been selected by Newmark and (c) the rights of Holders under this Article III (the “Article III Notice”). Newmark will include in any Public Offering all
Registrable Securities that Newmark is requested in writing, within 15 days after the date the Article III Notice is delivered by Newmark, to register by the Holders thereof (each, a “Piggy-back Registration”); provided,
however, that (A) if, at any time after giving the Article III Notice and prior to the effective date of the Registration Statement filed in connection therewith, Newmark shall determine to abandon such Public Offering, Newmark may give
written notice of such determination to all Holders who so requested registration, and thereafter Newmark shall be relieved of its obligation to register any Registrable Securities in connection with such abandoned Public Offering (without prejudice
to the other rights of Holders under this Article III), and (B) Newmark shall be permitted to delay such Public Offering for the same period and under the same circumstances as set forth in Section 2.3. No Piggy-back Registration effected
by Newmark under this Article III shall relieve Newmark of its obligations to effect Demand Registrations under Article II, except as otherwise set forth in Section 2.2. 

Section 3.2 Priority; Registration Form. If the managing underwriter(s) for a Piggy-back Registration that involves an
underwritten offering shall advise Newmark in good faith that in its opinion, the number of shares of Newmark Common Stock to be sold for the account of persons other than Newmark (collectively, “Selling Stockholders”) is greater
than the amount 

  
 -6- 








 
that can be offered without adversely affecting the success of the offering (taking into consideration the interests of Newmark and the Holders), then the number of shares of Newmark Common Stock
to be sold for the account of Selling Stockholders (including Holders) may be reduced to a number that, in the reasonable opinion of the managing underwriter(s), may reasonably be sold without having the adverse effect referred to above. The reduced
number of shares of Newmark Common Stock that may be registered in such Public Offering shall be allocated in the following priority: first, to shares of Newmark Common Stock proposed to be registered for offer and sale by Newmark;
second, to shares of Newmark Common Stock proposed to be registered pursuant to any demand registration rights of security holders of Newmark other than any Holder; and third, to Registrable Securities proposed to be registered by
Holders as a Piggy-back Registration. If the number of Registrable Securities proposed to be registered by Holders as a Piggy-back Registration is reduced pursuant to this Section 3.2, such Registrable Securities included in the Registration
Statement shall be allocated pro rata among the Holders participating in the Piggy-back Registration based on the number of Registrable Securities beneficially owned by the respective Holders. If, as a result of the proration provisions of this
Section 3.2, any Holder shall not be entitled to include all Registrable Securities in a registration pursuant to this Article III that such Holder has requested be included, such Holder may elect to withdraw its Registrable Securities from
such registration. 
 Article IV 

Registration Procedures 

Section 4.1 Use Reasonable Best Efforts. In connection with Newmark’s registration obligations pursuant to Article II and
Article III, Newmark shall use its reasonable best efforts to effect such registrations to permit the sale of such Registrable Securities in accordance with the intended method or methods of disposition thereof and pursuant thereto Newmark shall as
expeditiously as reasonably practicable: 
 (a) prepare and file with the SEC a Registration Statement or Registration Statements relating to
the registration on any appropriate form under the Securities Act, and to cause such Registration Statement to become effective as soon as reasonably practicable and to remain continuously effective for the time period required by this Agreement to
the extent permitted under the Securities Act; 
 (b) prepare and file with the SEC such amendments and post-effective amendments to each
Registration Statement as may be necessary to keep such Registration Statement effective for the time period required by this Agreement; cause the Registration Statement and the related Prospectus to be supplemented by any required Prospectus
supplement, and as so supplemented to be filed in accordance with the Securities Act and any rules and regulations promulgated thereunder; and otherwise comply with the provisions of the Securities Act as may be necessary to facilitate the
disposition of all Registrable Securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of disposition by the selling Holders thereof set forth in such Registration Statement or
such Prospectus or Prospectus supplement; 

  
 -7- 








 (c) notify the selling Holders and the managing underwriter(s), if any, promptly if at any time
(i) any Prospectus, Registration Statement or amendment or supplement thereto is filed, (ii) any Registration Statement, or any post-effective amendment thereto, becomes effective, (iii) the SEC or any other federal or state
governmental authority requests any amendment or supplement to, or any additional information in respect of, any Registration Statement or Prospectus, (iv) the SEC or any other federal or state governmental authority issues any stop order
suspending the effectiveness of a Registration Statement or initiates any proceedings for that purpose, (v) Newmark receives any notice that the qualification of any Registrable Securities for sale in any jurisdiction has been suspended or that
any proceeding has been initiated for the purpose of suspending such qualification, (vi) upon the discovery of any event which requires that any changes be made in such Registration Statement or any related Prospectus so that such Registration
Statement or Prospectus will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances under which
they were made (provided, however, that, in the case of this subclause (vi), such notice need only state that an event of such nature has occurred, without describing such event), (vii) of the determination by counsel of Newmark
that a post-effective amendment to a Registration Statement is advisable; or (viii) if, at any time, the representations and warranties of Newmark in any applicable underwriting agreement cease to be true and correct in all material respects.
Newmark hereby agrees to promptly reimburse any selling Holders for any reasonable out-of-pocket losses and expenses incurred in connection with any uncompleted sale of
any Registrable Securities in the event that Newmark fails to timely notify such Holder that the Registration Statement then on file with the SEC is no longer effective; 

(d) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement, or the
qualification of any Registrable Securities for sale in any jurisdiction, at the earliest reasonably practicable time; 
 (e) if requested by
the managing underwriter(s) or any Holder of Registrable Securities being sold in connection with an underwritten offering, incorporate into a Prospectus supplement or a post-effective amendment to the Registration Statement any information which
the managing underwriter(s), such Holder and Newmark reasonably agree is required to be included therein relating to such sale of Registrable Securities; and file such supplement or post-effective amendment as soon as practicable in accordance with
the Securities Act and the rules and regulations promulgated thereunder; 
 (f) furnish to each selling Holder and each managing underwriter,
if any, one signed copy of the Registration Statement or Registration Statements, any Newmark Free Writing Prospectus and any post-effective amendment thereto, including all financial statements and schedules thereto, all documents incorporated
therein by reference and all exhibits thereto (including exhibits incorporated by reference) as promptly as practicable after filing such documents with the SEC; 

(g) deliver to each selling Holder and each underwriter, if any, as many copies of the Prospectus or Prospectuses (including each preliminary
Prospectus) and any amendment, supplement or exhibit thereto as such Persons may reasonably request; and consent to the use of such Prospectus or any amendment, supplement or exhibit thereto by each such selling Holder and underwriter, if any, in
connection with the offering and sale of the Registrable Securities covered by such Prospectus, amendment, supplement or exhibit, in each case in accordance with the intended method or methods of disposition thereof; 

  
 -8- 








 (h) prior to any public offering of Registrable Securities, register or qualify, or cooperate
with the selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration or qualification of, such Registrable Securities for offer and sale under the securities or blue sky laws of such jurisdictions as
may be requested by the Holders of a majority of the Registrable Securities included in such Registration Statement; keep each such registration or qualification effective during the period that the applicable Registration Statement is required to
be maintained effective under this Agreement; and do any and all other acts or things necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by such Registration Statement; provided, however,
that Newmark will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to general service of process in any jurisdiction where it is not then so
subject; 
 (i) furnish to counsel selected by the Holders, prior to the filing of a Registration Statement or Prospectus or any supplement

Newmark’s control;

of Registrable Securities represented by such certificates;

clause (vi) of Section 4.1(c), promptly prepare and file a supplement or post-effective amendment to the applicable Registration Statement or Prospectus or any document incorporated therein by reference, and any other required documents,
so that such Registration Statement and Prospectus will not thereafter contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading, in light of the circumstances under
which they were made, and to cause such supplement or post-effective amendment to become effective as soon as practicable;

other actions in connection therewith as are reasonably necessary or desirable to expedite or facilitate the disposition of the Registrable Securities included in such Registration Statement and, in the case of an underwritten offering:

cause Newmark’s officers, directors, employees, attorneys and independent accountants to supply all information reasonably requested by any such selling Holders, underwriter(s), attorneys, accountants or agents in connection with such

kept confidential by it and, except as required by law, not disclosed by it, in each case, unless and until such information is made generally available to the public other than by such selling Holder; and each selling Holder of Registrable
Securities further agrees, on its own behalf and on behalf of all its underwriter(s), accountants, attorneys and agents, that it will, upon learning that disclosure of such information is sought in a court of competent jurisdiction, promptly give
notice to Newmark and allow Newmark at its expense, to undertake appropriate action to prevent disclosure of the information deemed confidential);

Prospectus until such Holder’s receipt of the copies of a supplemented or amended Prospectus or until it is advised in writing by Newmark that the use of the applicable Prospectus may be resumed, and, if so directed by Newmark such Holder will
deliver to Newmark all copies, other than permanent file copies, then in such Holder’s possession of any Prospectus covering such Registrable Securities. If Newmark shall have given any such notice during a period when a Demand Registration is

Covered Person under the Securities Act, common law or otherwise, to the extent that such Damages (or actions or proceedings in respect thereof) arise out of or result from (i) any untrue statement or alleged untrue statement of a material fact
contained in the Disclosure Package, any Registration Statement, the Prospectus, or in any amendment or supplement thereto, under which 

  
 -11- 








 
such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary Prospectus, together with the documents incorporated by
reference therein (as amended or supplemented if Newmark shall have filed with the SEC any amendment thereof or supplement thereto), if used prior to the effective date of such Registration Statement, or contained in the Prospectus, together with
the documents incorporated by reference therein (as amended or supplemented if Newmark shall have filed with the SEC any amendment thereof or supplement thereto), or the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that Newmark shall not be liable to any Holder Covered Person in any such case to
the extent that any such Damage (or action or proceeding in respect thereof) arises out of or relates to any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement or amendment thereof or
supplement thereto or in any such preliminary, final or summary Prospectus in reliance upon and in conformity with written information furnished to Newmark by or on behalf of any such Holder Covered Person specifically for use in the preparation
thereof. 
 Section 6.2 Indemnification by the Selling Holders. Each Holder selling Registrable Securities in any Registration
Statement filed pursuant to Article II or Article III will indemnify and hold harmless, severally and not jointly, Newmark, its directors, officers and agents and each Person controlling Newmark within the meaning of Section 15 of the
Securities Act (each, a “Newmark Covered Person”) against any and all Damages actually and as incurred by such Newmark Covered Person under the Securities Act, common law or otherwise, to the extent that such Damages (or actions or
proceedings in respect thereof) arise out of or result from any statement or alleged statement in or omission or alleged omission from the Disclosure Package, such Registration Statement, any preliminary, final or summary Prospectus contained
therein, any Holder Free Writing Prospectus for such Holder or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished
to Newmark or its representatives by or on behalf of any selling Holder specifically for use in the preparation of such Disclosure Package, Registration Statement, preliminary, final or summary Prospectus, Holder Free Writing Prospectus or amendment
or supplement thereto. In no event shall the liability of any Holder hereunder be greater than the net proceeds received by such Holder under the sale of the Registrable Securities giving rise to such indemnification obligation. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on behalf of Newmark or any of its directors, officers, agents or controlling Persons. Newmark may require as a condition to its including Registrable Securities in any
Registration Statement filed hereunder that each such selling Holder acknowledge its agreement to be bound by the provisions of this Agreement (including this Article VI) applicable to it. 

Section 6.3 Notices of Claims. Promptly after receipt by a Holder Covered Person or a Newmark Covered Person (each, an
“Indemnified Party”) of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Article VI, such Indemnified Party will, if a claim in respect
thereof is to be made against, respectively, Newmark, on the one hand, or any selling Holder, on 

  
 -12- 








 
the other hand (such Person or Persons, the “Indemnifying Party”), give written notice to the latter of the commencement of such action; provided, however, that the
failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its or their obligations under this Article VI, except to the extent that the Indemnifying Party is actually materially prejudiced by such
failure to give notice, and in no event shall such failure relieve the Indemnifying Party from any other liability that it may have to such Indemnified Party. If any such claim or action shall be brought against an Indemnified Party, and it shall
notify the Indemnifying Party thereof in accordance with this Section 6.3, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, to assume the defense thereof with counsel reasonably satisfactory to
the Indemnified Party, and after notice from the Indemnifying Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party shall not be liable to such Indemnified Party under this Article VI for any legal or
other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, other than reasonable cost of investigation; provided, further, that if, in the Indemnified Party’s reasonable judgment, a
conflict of interest between the Indemnified Party and the Indemnifying Party exists in respect of such claim, then such Indemnified Party shall have the right to participate in the defense of such claim and to employ one firm of attorneys at the
Indemnifying Party’s expense to represent such Indemnified Party. No Indemnified Party will consent to entry of any judgment or enter into any settlement without the Indemnifying Party’s written consent to such judgment or settlement,
which shall not be unreasonably withheld, conditioned or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of any judgment or enter into any settlement in respect of which the
Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim
or proceeding. 
 Section 6.4 Contribution. If the indemnification provided for in this Article VI is unavailable or
insufficient to hold harmless an Indemnified Party under this Article VI, then each Indemnifying Party shall have a several and not joint obligation to contribute to the amount paid or payable by such Indemnified Party as a result of the Damages
referred to in this Article VI in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand, in connection with the offering that resulted in such
Damages, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether an untrue or alleged untrue statement of a material fact or an omission or alleged omission to state
a material fact relates to information supplied by the Indemnifying Party or the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statements or omission.
Notwithstanding anything in this Section 6.4 to the contrary, no Holder shall be required to contribute any amount pursuant to this Section 6.4 in excess of the amount by which (i) the net proceeds received by such Holder from the
sale of Registrable Securities in the offering to which the misstatement or omission relates exceeds (ii) the amount of any Damages which such Holder has otherwise been required to pay by reason of such misstatement or omission. Newmark and the
Holders agree that it would not be just and equitable if contributions pursuant to this Section 6.4 were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations
referred to in this Section 6.4. The amount paid by an Indemnified Party as a 

  
 -13- 








 
result of the Damages referred to in the first sentence of this Section 6.4 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection
with investigating or defending any action or claim (which shall be limited as provided in Section 6.3 if the Indemnifying Party has assumed the defense of any such action in accordance with the provisions thereof) that is the subject of this
Section 6.4. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Promptly
after receipt by an Indemnified Party under this Section 6.4 of notice of the commencement of any action against such party in respect of which a claim for contribution may be made against an Indemnifying Party under this Section 6.4, such
Indemnified Party shall notify the Indemnifying Party in writing of the commencement thereof if the notice specified in Section 6.3 has not been given with respect to such action; provided, however, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its or their obligations under this Article VI, except to the extent that the Indemnifying Party is actually materially prejudiced by such failure to
give notice, and in no event shall such failure relieve the Indemnifying Party from any other liability that it may have to such Indemnified Party. 

Article VII 
 Rule 144

 Section 7.1 Rule 144. Newmark shall file the reports required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations promulgated thereunder, so long as it is subject to such reporting requirements, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the
Securities Act within the limits of the exemptions provided by Rule 144 of the Securities Act (“Rule 144”). Upon the request of a Holder, Newmark shall deliver to such Holder a written statement stating whether it has complied with
such requirements and will take such further action as such Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the
limits of the exemptions provided by Rule 144. 
 Article VIII 

Underwritten Registrations 

Section 8.1 Selection of Underwriter(s). In each registration under Article II or Article III, the underwriter or underwriters and
managing underwriter or managing underwriters that will administer the offering shall be selected by Newmark; provided, however, that in the case of a registration under Article II, such underwriter(s) and managing underwriter(s) shall
be subject to the approval by the Holders of a majority in aggregate amount of Registrable Securities included in such offering, which approval shall not be unreasonably withheld or delayed. 

Section 8.2 Agreements of Selling Holders. No Holder shall sell any of its Registrable Securities in any underwritten offering
pursuant to a registration hereunder unless such Holder (i) agrees to sell such Registrable Securities on a basis provided in any underwriting agreement in customary form, including the making of customary representations, warranties and


  
 -14- 








 
indemnities and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting
agreements or as reasonably requested by Newmark (whether or not such offering is underwritten). 
 Article IX 

Holdback Agreements 

Section 9.1 Restrictions on Public Sales by Holders. To the extent not inconsistent with applicable law, each Holder that is
timely notified in writing by the managing underwriter(s) or underwriter(s) shall not effect any public sale or distribution (including a sale pursuant to Rule 144) of any securities of Newmark of the same class or series being registered in an
underwritten offering (other than pursuant to an employee stock option, stock purchase, stock bonus or similar plan, or pursuant to a merger, exchange offer or transaction of the type specified in Rule 145(a) under the Securities Act) or any
securities of Newmark convertible into or exchangeable or exercisable for securities of the same class or series, during the seven-day period prior to the effective date of the applicable Registration
Statement, if such date is known, or during the period beginning on such effective date and ending either (i) 60 days after such effective date or (ii) any such earlier date as may be requested by the managing underwriter(s) or underwriter(s)
of such registration, except as part of such registration.
