 SECOND SUPPLEMENTAL INDENTURE 

This Second Supplemental Indenture, dated as of December 9, 2014 (this “Second Supplemental Indenture”), by and between
BGC PARTNERS, INC., a corporation duly organized and existing under the laws of the State of Delaware (the “Company”), having its principal executive office located at 499 Park Avenue, New York, New York 10022; and U.S. BANK

 RECITALS OF THE COMPANY 

WHEREAS, the Company has duly authorized the execution and delivery of the Indenture to provide for the issuance from time to time of its
debentures, notes or other evidences of indebtedness to be issued in one or more series as provided for in the Indenture; 
 WHEREAS, the
Indenture provides that the Securities of a series shall be in the form and shall have such terms and provisions as may be established by or pursuant to a Board Resolution and set forth in an Officers’ Certificate or as may be established in
one or more supplemental indentures thereto; 
 WHEREAS, the Company has determined to issue a series of senior Securities under the
Indenture designated as the Company’s “5.375% Senior Notes due 2019” (hereinafter called the “Notes”) pursuant to the terms of this Second Supplemental Indenture and substantially in the form as herein set forth, with
such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture and this Second Supplemental Indenture; and  

WHEREAS, the Company, by action duly taken, has authorized the execution of this Supplemental Indenture and the issuance of the Notes; 

NOW, THEREFORE, THIS SECOND SUPPLEMENTAL INDENTURE WITNESSETH: 

For and in consideration of the premises stated herein and the purchase of the Notes by the Holders thereof, the parties hereto hereby enter
into this Second Supplemental Indenture, for the equal and proportionate benefit of all Holders of the Notes, as follows: 
 ARTICLE I.

 DEFINITIONS 

SECTION 1.1. Certain Terms Defined in the Indenture. 

For purposes of this Second Supplemental Indenture and the Notes, all capitalized terms used but not defined herein shall have the meanings
ascribed to such terms in the Indenture, as amended and supplemented hereby (and in the case of the term “Indebtedness,” with respect to the Notes, the definition set forth below shall supersede and replace the definition set forth in the
Indenture). 







 SECTION 1.2. Definitions. 

For the benefit of the Holders of the Notes, Section 101 of the Indenture shall be amended by adding or substituting, as applicable, the
following new definitions: 
 “Below Investment Grade Rating Event” means the Notes cease to be rated at or above an
Investment Grade Rating by at both Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by the Company of any Change of Control (or pending Change of Control)
and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as either of the Rating Agencies has publicly announced that it is considering a
possible ratings change). If a Rating Agency is not providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade by such Rating Agency during that Trigger Period.

 “Change of Control” means the occurrence of any of the following: 

(1) a “person” or “group” within the meaning of Section 13(d) of the Exchange Act other than the
Company, its Subsidiaries and their respective employee benefit plans and any Permitted Holder, has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the Company’s capital stock
representing, in the aggregate, more than 50% of the voting power of all classes of such capital stock; or 
 (2) one or more
Permitted Holders shall cease to (i) own and control, beneficially, capital stock of the Company that possesses the voting power under normal circumstances to cast 50% or more of the total votes entitled to be cast for the election of directors
of the Company; or (ii) have the voting power or the contractual right to elect a majority of the directors of the Company; or 

(3) a liquidation or dissolution of the Company or the stockholders of the Company approve any plan or proposal for the
liquidation or dissolution of the Company; or 
 (4) any conveyance, transfer, sale, lease or other disposition of all or
substantially all of the properties and assets of the Company to another Person, other than: 
 (A) any transaction: 

(i) that does not result in any reclassification, conversion, exchange or cancellation of the outstanding equity interests of
the Company; or 
 (ii) pursuant to which holders of the outstanding equity interests of the Company, immediately prior to
the transaction, have the entitlement to exercise, 

  
 2 








 
directly or indirectly, 50% or more of the total voting power of all equity interests entitled to vote generally in elections of directors or managers of the continuing or surviving or successor
entity immediately after giving effect to such issuance; or 
 (B) any transfer of assets or similar transaction solely for
the purpose of changing the Company’s jurisdiction of organization and resulting in a reclassification, conversion or exchange of the outstanding equity interests of the Company, if at all, solely into outstanding equity interests of the
surviving entity or a direct or indirect parent of the surviving entity; or 
 (C) any conveyance, transfer, sale, lease or
other disposition with or into any of the subsidiaries of the Company, so long as such conveyance, transfer, sale, lease or other disposition is not part of a plan or a series of transactions designed to or having the effect of merging or
consolidating with, or conveying, transferring, selling, leasing or disposing all or substantially all its properties and assets to, any other Person. 

Notwithstanding the foregoing, no Change of Control will be deemed to have occurred in the event any successor issuer of the Notes shall be a corporation so
long as one or more Permitted Holders shall maintain the beneficial ownership of shares of the capital stock of such successor possessing the voting power under normal circumstances to elect, or one or more Permitted Holders shall have the
contractual right to elect, a majority of the directors of such successor corporation. Notwithstanding the foregoing, a transaction will not be deemed to result in a Change of Control if (a) Cantor Fitzgerald L.P. becomes a wholly owned
subsidiary of a holding company and (b) the holders of the voting capital stock of such holding company immediately following that transaction are substantially the same as the holders of Cantor Fitzgerald L.P.’s voting partnership
interests immediately prior to that transaction. 
 “Change of Control Triggering Event” means the occurrence of both a
Change of Control and a Below Investment Grade Rating Event. 
 “Designated Subsidiary” means each of (i) BGC
Holdings, L.P., (ii) BGC Global Holdings, L.P., (iii) BGC Partners, L.P. and (iv) any other direct or indirect subsidiary now owned or hereafter acquired by the Company for which (a) the Net Assets of such subsidiary constitute,
as of the last day of the most recently ended fiscal quarter, 5% or more of the Total Stockholders’ Equity of the Company or (b) the net revenues of such subsidiary constitute, as of the last day of the most recently ended fiscal quarter,
10% or more of the consolidated net revenues of the Company during the most recently ended period of four consecutive fiscal quarters; provided, however, that none of the following shall be a Designated Subsidiary:  

(1) any Person in which the Company or any of its Subsidiaries does not own sufficient equity or voting interests to elect a
majority of the directors (or persons performing similar functions); 
 (2) any Person whose financial results would not be
consolidated with those of the Company and its consolidated subsidiaries in accordance with United States generally accepted accounting principles; and 

  
 3 








 (3) any subsidiary of any Person described in clauses (1) and
(2) above.

Person, whether or not contingent:

(3) all obligations of such Person issued or assumed as the deferred purchased price of property, all conditional sale
obligations and all obligations under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business); 

(4) all obligations of such Person for the reimbursement of any obligor on any banker’s acceptance, bank guarantees,
surety bonds or similar credit transaction; and 
 (5) any amendments, modifications, refundings, renewals or extensions of
any indebtedness or obligation described as “Indebtedness” in clauses (1) through (4) above; 
 if and to the extent any of the
preceding items (other than letters of credit) would appear as a liability upon a balance sheet of such Person prepared in accordance with United States generally accepted accounting principles; provided, however, the term
‘‘Indebtedness’’ includes all of the following items, whether or not any such items would appear as a liability on a balance sheet of such Person prepared in accordance with such generally accepted accounting principles: 

  

	 	(i)	all Indebtedness of others secured by any mortgage, pledge, lien, security interest or other encumbrance on any property or asset of such Person (whether or not such Indebtedness is assumed by such Person);


  

	 	(ii)	to the extent not otherwise included, any guarantee by such Person of Indebtedness of any other Person; and 

  

	 	(iii)	preferred stock or other equity interests providing for mandatory redemption or sinking fund or similar payments issued by any subsidiary of such Person.

benefit or for the benefit of his spouse, any of his descendants or any of his relatives, in each case, so long as he is alive and, upon his death or incapacity, any person who shall, as a result of Mr. Lutnick’s death or incapacity,
become a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of the Company’s capital stock by operation of a trust, by will or the laws of descent and distribution or by operation of law. 

“Rating Agencies” means (1) each of Fitch and S&P; and (2) if any of Fitch or S&P ceases to rate the Notes
or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act,
selected by the Company (as certified by a Board Resolution) as a replacement agency for Fitch or S&P, or all of them, as the case may be.

conformity with United States generally accepted accounting principles, would be included under total stockholders’ equity on a consolidated statement of financial condition of the Company. For purposes of determining Total Stockholders’
Equity, the Company may include the amount of any capital to be returned pursuant to the terms of the Agreement of Limited Partnership of BGC Holdings, L.P., as amended from time to time, to any limited or general partner who has been terminated or
withdrawn until such time as the amount of such partners’ capital has been paid to such limited or general partner pursuant to the terms of the Company’s Partnership Agreement plus, without duplication, redeemable partnership interest
representing former partner’s equity in the Company. For the avoidance of doubt, Total Stockholders’ Equity is inclusive of noncontrolling interests in subsidiaries on the Company’s consolidated statement of financial condition.

 SECTION 2.2. Certain Terms of the Notes. 

The following terms relating to the Notes are hereby established: 

(a) Title. The Notes shall constitute a series of senior Securities having the title “5.375% Senior Notes due 2019.”

 (b) Principal Amount. The aggregate principal amount of the Notes that may be initially authenticated

HUNDRED MILLION DOLLARS ($300,000,000.00). The Company may, from time to time, without notice to, or the consent of, the Holders of the Notes, issue and sell additional Securities (“Additional Securities”) ranking equally and
ratably with the Notes in all respects (other than the issue date, and to the extent applicable, issue price, initial date of interest accrual and initial interest payment date of such Additional Securities), provided that such
Additional Securities are fungible with the previously issued Notes for U.S. federal income tax purposes. Any such Additional Securities shall be consolidated and form a single series with the Notes for all purposes under the Indenture,
including voting. 
 (c) Maturity Date. The entire outstanding principal of the Notes shall be payable on
December 9, 2019 (the “Maturity Date”). 
 (d) Interest Rate. Subject to any adjustment pursuant to
Section 2.7 below, the rate at which the Notes shall bear interest shall be 5.375% per annum, computed on the basis of a 360-day year comprised of twelve 30-day months; the date from which interest shall accrue on the Notes shall be
December 9, 2014, or the most recent Interest Payment Date to which interest has been paid or duly provided for; the Interest Payment Dates for the Notes shall be the 9th day of June and
December of each year, commencing on June 9, 2015; the interest so payable, and punctually paid or duly provided for, on any Interest Payment Date, will be paid, in immediately available funds, to the Persons in whose names the Notes (or one or
more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the 25th day of May and November (whether or not a Business Day),
as the case may be, next preceding such Interest Payment Date. Any such interest not punctually paid or duly provided 

  
 10 








 
for shall forthwith cease to be payable to the respective Holders on such Regular Record Date, and such defaulted interest may be paid to the Persons in whose names the Notes (or one or more
Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 10 days prior to such
Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture. Payment of principal of, and premium, if any, and interest on, the Notes will be made at the Corporate Trust Office of the Trustee or such other office or agency of the Company as may be designated for such purpose, in
such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that each installment of interest, premium, if any, and principal on the Notes
may at the Company’s option be paid in immediately available funds by wire transfer to an account maintained by the payee located in the United States.  

(e) Currency. The currency of denomination of the Notes is United States dollars. Payment of principal of and interest on the Notes
will be made in United States dollars.

option to redeem the Notes, in whole or in part, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed and (ii) the sum of the present values of the Remaining Scheduled
Payments, plus, in each case, accrued and unpaid interest thereon to, but excluding, the Redemption Date, subject to the rights of Holders to be redeemed on the relevant Record Date to receive interest due on the relevant Interest Payment Date. 

In determining the present values of the Remaining Scheduled Payments, the Company will discount such payments to the redemption date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points. 

For purposes of the foregoing: 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment
Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate

 “Comparable Treasury Price”
means, with respect to any Redemption Date, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, (2) if the
Company obtains fewer than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations for such Redemption Date or (3) if only one Reference Treasury Dealer Quotation is
received, such quotation. 

  
 11 








 “Independent Investment Banker” means one of the Reference
Treasury Dealers, or their respective successors, as may be appointed from time to time by the Company; provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “primary treasury
dealer”), the Company will substitute another primary treasury dealer. 
 “Reference Treasury Dealer” means
Morgan Stanley & Co. LLC and three other primary treasury dealers selected by the Company, and each of their respective successors and any other primary treasury dealers selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such
Reference Treasury Dealer as of 3:30 p.m., New York City time, on the third business day preceding such Redemption Date. 

“Remaining Scheduled Payments” means, with respect to any note to be redeemed, the remaining scheduled payments of the
principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Note, the amount of the next
scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date. 
 ”Treasury
Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the applicable
Comparable Treasury Issue. In determining this rate, the Company will assume a price for the applicable Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such
redemption date. 
 (c) Interest Payable. On and after any Redemption Date for the Notes, interest will cease to accrue on the Notes
or any portion thereof called for redemption, unless the Company defaults in the payment of the Redemption Price. 
 SECTION 2.4. Offer
to Repurchase Upon a Change of Control Triggering Event. 
 If a Change of Control Triggering Event occurs, unless the Company has
exercised its right to redeem the Notes as described above, holders of the Notes will have the right to require the Company to repurchase all or any part (in integral multiples of $2,000 original principal amount and $1,000 in excess thereof) of
their Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the then outstanding aggregate principal
amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to, but not including, the date of purchase (the “Change of Control Payment”). Within 30 days following


  
 12 








 
any Change of Control Triggering Event, the Company will be required to mail a notice to holders of the Notes (with a copy to the Trustee) describing the transaction or transactions that
constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change
of Control Payment Date”), pursuant to the procedures described herein and in such notice. The Company must comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of
Control provisions herein, the Company will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts.

 Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer upon the occurrence of a Change of
Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control Offer made by the Company and the third party repurchases all Notes properly tendered
and not withdrawn under its offer. In addition, the Company will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the Indenture, other than a default in the payment of
the Change of Control Payment upon a Change of Control Triggering Event. 
 On the Change of Control Payment Date, the Company will be
required, to the extent lawful, to (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer; (ii) deposit with the Trustee, acting as paying agent, an amount equal to the Change of
Control Payment in respect of all Notes or portions thereof Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate
principal amount of Notes or portions of Notes being purchased. 
 SECTION 2.5. Limitation on Liens on Capital Stock of Designated
Subsidiaries. 
 The Company covenants and agrees for the benefit of the Holders of the Notes that, for so long as any of the
Notes are Outstanding, the Company will not, and the Company will not permit any Designated Subsidiary to, create, assume, incur, guarantee or otherwise permit to exist any Indebtedness secured by any mortgage, pledge, lien, security interest or
other encumbrance (a “lien”) upon any shares of Capital Stock of any Designated Subsidiary directly or indirectly held by the Company (whether such Capital Stock are now owned or hereafter acquired) without effectively providing
concurrently that the Notes (and, if the Company so elects, any other Indebtedness of the Company that is not subordinate to the Notes and with respect to which the governing instruments of such Indebtedness require, or pursuant to which the Company
is otherwise obligated, to provide such security) will be secured equally and ratably with, or prior to, such Indebtedness for at least the time period such other Indebtedness is so secured. This covenant shall not apply to liens on the Capital
Stock of any Person existing at the time it becomes a Designated Subsidiary (and any extensions, renewals or replacements thereof). 

  
 13 








 SECTION 2.6. Use of Net Proceeds . (a) The Company covenants and agrees for the
benefit of the Holders of the Notes that the net proceeds from the offering of the Notes (after deducting the initial purchasers’ discount and fees and expenses payable by the Company in connection with the offering of the Notes) to lend to its
Subsidiaries pursuant to one or more promissory notes. So long as any of the Notes are Outstanding, (1) the aggregate principal amount of all such promissory notes shall not be less than the amount of the net proceeds from the offering of the
Notes (or, if less, the aggregate principal amount of Notes then Outstanding), (2) such promissory notes shall bear interest at rates that shall not be less than that borne by the Notes and (3) such promissory notes shall have terms not
later than the Maturity Date; provided that any transfer of such obligation from one Subsidiary to another or any refinancing of any such obligation by another Subsidiary shall be permitted from time to time. 

(b) The Company covenants and agrees that so long as any of the Notes are Outstanding, any Indebtedness for borrowed money the Company incurs
after the date hereof in one transaction, or in a series of related transactions, that is in excess of $25,000,000.00 will be subject to a similar covenant. 

SECTION 2.7. Interest Rate Adjustments Based on Ratings Events 

(a) The interest rate payable on the Notes will be subject to adjustments from time to time if each of Fitch and S&P downgrades (or
subsequently upgrades) the debt rating assigned to the notes, in the manner described below. 
 (b) If the rating from each of Fitch and
S&P of the notes is decreased to a rating set forth in the immediately following table (a “Downgrade Event”), the interest rate on the Notes will increase such that it will equal the interest rate payable on the notes on the
date of the initial issuance of Notes plus the percentage set forth opposite the applicable rating from the table below: 
  

					
	 Debt Rating (Fitch and S&P)
	  	Percentage	 
	 BBB- or higher
	  	 	—  	  
	 BB+
	  	 	0.50	% 
	 BB or lower
	  	 	1.00	% 

 For the avoidance of doubt, any increase in the interest payable on the Notes shall require a decrease in the
rating of the Notes by each of Fitch and S&P to the relevant threshold ratings set forth above. 
 (c) If, subsequent to a Downgrade
Event, either of Fitch or S&P increases its respective rating of the Notes to any of the threshold ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the notes equals the interest rate
payable on the Notes on the date of the initial issuance of the Notes plus the percentage set forth opposite the applicable rating from the table above. For the avoidance of doubt, any decrease in the interest payable on the notes shall require an
increase in the rating of the notes by only one of Fitch and S&P to relevant threshold ratings set forth above. 
 (d) For so long as
(i) only one of Fitch or S&P provides a rating of the Notes or (ii) the Notes are not rated by either Fitch or S&P, the interest rate on the Notes will increase such that it will equal the interest rate payable on the notes on the
date of the initial issuance of the notes plus 1.00% per annum. 

  
 14 








 (e) Any interest rate increase or decrease described above will take effect from the first day of
the interest period during which a rating change requires an adjustment in the interest rate. If Fitch or S&P changes its rating of the notes more than once during any particular interest period, the last change by Fitch or S&P, as
applicable, will control for purposes of any interest rate increase or decrease with respect to the Notes described above relating to Fitch’s or S&P’s, as applicable, action. 

(f) The Company will communicate an increase or decrease in the interest rate applicable to the Notes pursuant to the Section 2.7 to the
trustee in the form of an Officers’ Certificate. 
 (g) The term “interest,” as used in the Indenture with respect to the
Notes, shall be deemed to include any such additional interest applicable pursuant to this Section 2.7, unless the context otherwise requires. 

SECTION 2.8. Reports to Holders. The Company covenants and agrees for the benefit of the Holders of the Notes that, for so long as any
of the Notes are Outstanding, during any period in which the Company is not required to file reports pursuant to Section 13 or 15(d) of the Exchange Act, the Company will (i) make available to all Holders of Notes (including by posting on
the Company’s website), without cost to such Holders, copies of annual reports and quarterly reports containing information that is substantially similar to the information that is required to be contained in such reports that the Company would
have been required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act if it were subject thereto (other than exhibits or any information that would have been required by Items 402 and 404 of Regulation S-K under the
Securities Act) and (ii) promptly, upon request, supply copies of such reports to any prospective Holder of Notes. The Company will make available such information to the Holders of Notes within 15 days after the respective dates by which a
periodic report on Form 10-K or Form 10-Q, as the case may be, in respect of such information would have been required to be filed with the Commission if the Company were subject to Section 13 or 15(d) of the Exchange Act as a non-accelerated
filer, as such term is defined in Rule 12b-2 under the Exchange Act. 
 SECTION 2.9. Events of Default. 

Section 501(3) of the Indenture shall not be applicable to the Notes. 

Section 501(4) of the Indenture shall be superseded and replaced with respect to the Notes by the following: 

(4) Default in the performance, or breach, of any covenant or warranty of the Company in this Indenture or any of the
Securities of such series (other than a covenant or warranty for which the consequences of breach or nonperformance are addressed elsewhere in this Section 501 or a covenant or warranty which has expressly been included in this Indenture,
whether or not by means of a supplemental indenture, solely for the benefit of Securities of a series other than such series), and continuance of such default or breach (without such default or breach having been waived in accordance of the
provisions of this Indenture) for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding
Securities of such series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 

  
 15 








 The following additional Event of Default shall be applicable to the Notes pursuant to
Section 501(7): 
 A default by the Company in the payment in respect of any Indebtedness for borrowed money, including
obligations evidenced by any mortgage, indenture, bond, debenture, note, guarantee or similar instrument, in an aggregate principal amount of at least $50 million beyond any applicable grace period, or default in the performance or compliance with
any term respecting such debt, if as a consequence such debt becomes due and payable before its date of maturity, and such default shall not have been rescinded or annulled or such Indebtedness shall not have been discharged and such default
continues for period of fifteen consecutive days after written notice to the Company by the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes.

	No. [—]	  	
		
	CUSIP: [—]	  	

 BGC PARTNERS, INC., a Delaware corporation (herein called the “Company,” which term includes
any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of [•] ($[•]) on December 9, 2019 (the “Maturity
Date”) (except to the extent redeemed or repaid prior to the Maturity Date) and to pay interest thereon from December 9, 2014 (the “Original Issue Date”) or from the most recent Interest Payment Date to which interest
has been paid or duly provided for at the rate of 5.375% per annum, on the 9th day of June and December (of each year each such date, an “Interest Payment Date”), commencing
on June 9, 2015, until the principal hereof is paid or made available for payment. 
 Payment of Interest. The interest so
payable, and punctually paid or made available for payment, on any Interest Payment Date, will, as provided in the Indenture, be paid, in immediately available funds, to the Person in whose name this Note (or one or more Predecessor Securities) is
registered at the close of business on the 25th day of May and November (whether or not a Business Day, as defined in the Indenture referred to herein), as the case may be, next preceding such
Interest Payment Date (the “Regular Record Date”). Any such interest not punctually paid or duly provided for (“Defaulted Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date, and
such Defaulted Interest may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a special record date (the “Special Record Date”) for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with requirements of any
securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. 

Place of Payment. Payment of principal, premium, if any, and interest on this Note will be made at the Corporate Trust Office of the
Trustee or such other office or agency of the Company as may be designated for such purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided,
however, that each installment of interest, premium, if any, and principal on this Note may at the Company’s option be paid in immediately available funds by wire transfer to an account maintained by the payee located in the United
States. 
 Time of Payment. In any case where any Interest Payment Date, the Maturity Date or any date fixed for redemption of the
Notes shall not be a Business Day, then (notwithstanding any other provision of the Indenture or this Note), payment of principal, premium, if any, or interest, if any, need not be made on such date, but may be made on the next


  
 A-4 








 
succeeding Business Day with the same force and effect as if made on such Interest Payment Date, the Maturity Date or the date so fixed for redemption or repayment, as the case may be, and no
interest shall accrue in respect of the delay. 
 General. This Note is one of a duly authorized series of Securities of the Company,
issued and to be issued in one or more series under an indenture (the “Base Indenture”), dated as of June 26, 2012, among the Company, U.S. Bank National Association, as trustee (herein called the
“Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Note is a part), as supplemented by a Second Supplemental Indenture thereto, dated as of
December 9, 2014 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company and the Trustee. Reference is hereby made to the
Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated
and delivered; provided that to the extent of any inconsistency between the terms and provisions in the Indenture and those contained in this Note, the Indenture shall govern. This Note is one of a duly authorized series of Securities
designated as “5.375% Senior Notes due 2019” (collectively, the “Notes”), initially limited in aggregate principal amount to [—] ($[—]). 
 Further Issuance. The Company may, from time to time, without notice to, or the
consent of, the Holders of the Notes, issue and sell additional Securities (“Additional Securities”) ranking equally and ratably with the Notes in all respects (other than the issue date, and to the extent applicable,
issue price, initial date of interest accrual and initial interest payment date of such Additional Securities), provided that such Additional Securities are fungible with the previously issued Notes for U.S. federal income tax purposes.
Any such Additional Securities shall be consolidated and form a single series with the Notes for all purposes under the Indenture, including voting. 

Events of Default. If an Event of Default with respect to the Notes shall have occurred and be continuing, the principal of the Notes
may be declared due and payable in the manner and with the effect provided in the Indenture. 
 Sinking Fund. The Notes are not
subject to any sinking fund. 
 Optional Redemption. At any time and from time to time, the Company will be entitled at its option to
redeem the Notes, in whole or in part, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments, plus,
in each case, accrued and unpaid interest thereon to, but excluding, the Redemption Date, subject to the rights of Holders to be redeemed on the relevant Record Date to receive interest due on the relevant Interest Payment Date. 

In determining the present values of the Remaining Scheduled Payments, the Company will discount such payments to the redemption date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points. 

  
 A-5 








 For purposes of the foregoing: 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as
having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of such Notes. 
 “Comparable Treasury Price” means, with
respect to any Redemption Date, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, (2) if the Company
obtains fewer than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations for such Redemption Date or (3) if only one Reference Treasury Dealer Quotation is received,
such quotation. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers, or their respective
successors, as may be appointed from time to time by the Company; provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “primary treasury dealer”), the Company will
substitute another primary treasury dealer. 
 “Reference Treasury Dealer” means Morgan Stanley & Co. LLC
and three other primary treasury dealers selected by the Company, and each of their respective successors and any other primary treasury dealers selected by the Company. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference
Treasury Dealer as of 3:30 p.m., New York City time, on the third business day preceding such Redemption Date. 
 “Remaining
Scheduled Payments” means, with respect to any note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided,
however, that, if such redemption date is not an interest payment date with respect to such Note, the amount of the next scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date. 

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent
yield to maturity (computed as of the third business day immediately preceding that redemption date) of the applicable Comparable Treasury Issue. In determining this rate, the Company will assume a price for the applicable Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date. 

  
 A-6 








 Interest Rate Adjustments Based on Ratings Events. 

(a) The interest rate payable on the Notes will be subject to adjustments from time to time if each of Fitch and S&P downgrades (or
subsequently upgrades) the debt rating assigned to the notes, in the manner described below. 
 (b) If the rating from each of Fitch
and S&P of the notes is decreased to a rating set forth in the immediately following table (a “Downgrade Event”), the interest rate on the Notes will increase such that it will equal the interest rate payable on the notes on the
date of the initial issuance of Notes plus the percentage set forth opposite the applicable rating from the table below:  
  

			
	 Debt Rating (Fitch and S&P)
	  	Percentage
	 BBB- or higher
	  	—  
	 BB+
	  	0.50%
	 BB or lower
	  	1.00%

 For the avoidance of doubt, any increase in the interest payable on the Notes shall require a decrease in the
rating of the Notes by each of Fitch and S&P to the relevant threshold ratings set forth above. 
 (c) If, subsequent to a Downgrade
Event, either of Fitch or S&P increases its respective rating of the Notes to any of the threshold ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the notes equals the interest rate
payable on the Notes on the date of the initial issuance of the Notes plus the percentage set forth opposite the applicable rating from the table above. For the avoidance of doubt, any decrease in the interest payable on the notes shall require an
increase in the rating of the notes by only one of Fitch and S&P to relevant threshold ratings set forth above. 
 (d) For so long as
(i) only one of Fitch or S&P provides a rating of the Notes or (ii) the Notes are not rated by either Fitch or S&P, the interest rate on the Notes will increase such that it will equal the interest rate payable on the notes on the
date of the initial issuance of the notes plus 1.00% per annum. 
 (e) Any interest rate increase or decrease described above will take
effect from the first day of the interest period during which a rating change requires an adjustment in the interest rate. If Fitch or S&P changes its rating of the notes more than once during any particular interest period, the last change by
Fitch or S&P, as applicable, will control for purposes of any interest rate increase or decrease with respect to the Notes described above relating to Fitch’s or S&P’s, as applicable, action. 

(f) The Company will communicate an increase or decrease in the interest rate applicable to the Notes pursuant to the Section 2.7 of the
Second Supplemental Indenture to the trustee in the form of an Officers’ Certificate. 

  
 A-7 








 (g) The term “interest,” as used in the Indenture with respect to the Notes, shall be
deemed to include any such additional interest applicable pursuant to Section 2.7 of the Second Supplemental Indenture, unless the context otherwise requires. 

Offer to Repurchase Upon a Change of Control Triggering Event. If a Change of Control Triggering Event occurs, unless the Company has
exercised its right to redeem the Notes as described above under “Optional Redemption,” holders of the Notes will have the right to require the Company to repurchase all or any part (in integral multiples of $2,000 original principal
amount and integral multiples of $1,000 in excess thereof) of their Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will be required to offer payment in cash
equal to 101% of the then outstanding aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to, but not including, the date of purchase (the “Change of Control Payment”).
Within 30 days following any Change of Control Triggering Event, the Company will be required to mail a notice to holders of the Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to
repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures
described herein and in such notice. The Company must comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be required to
comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts. 

Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control
Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control Offer made by the Company and the third party repurchases all Notes properly tendered and not
withdrawn under its offer. In addition, the Company will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the Indenture, other than a default in the payment of the
Change of Control Payment upon a Change of Control Triggering Event. 
 On the Change of Control Payment Date, the Company will be required,
to the extent lawful, to (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; (ii) deposit with the Trustee, acting as paying agent, an amount equal to the Change of Control
Payment in respect of all Notes or portions of Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of
Notes or portions of Notes being purchased. 
 Defeasance and Covenant Defeasance. The Indenture contains provisions for defeasance
at any time of (a) the entire indebtedness of the Company on this Note and (b) certain restrictive covenants and the related Events of Default, in each case which provisions shall apply to this Note.

 Modification and Waivers; Obligations of the Company Absolute. The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities. Such amendment may be effected under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority in
aggregate principal amount of the Securities at the time outstanding, on behalf of the Holders of all outstanding Securities, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture
permit the Holders of not less than a majority in aggregate principal amount of the outstanding Securities of individual series to waive on behalf of all of the Holders of Securities of such individual series certain past defaults under the
Indenture and their consequences. Any such consent or waiver shall be conclusive and binding upon the Holder of this Note and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 No reference herein to the Indenture and no
provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, and premium, if any, and interest on, this Note at the time, place, and rate, and in the
coin or currency, herein prescribed. 
 Limitation on Suits. As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect
to the Notes, the Holders of not less than 25% in principal amount of the outstanding Notes shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceedings as trustee, and the Trustee shall not have
received from the Holders of a majority in principal amount of the outstanding Notes a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations
do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of or interest on, and any Additional Amounts with respect to, this Note on or after the respective due dates expressed herein. 

Authorized Denominations. The Notes are issuable only in registered form in minimum denominations of $2,000 and integral multiples of
$1,000 in excess thereof. 
 Registration of Transfer or Exchange. As provided in the Indenture and subject to certain limitations
herein and therein set forth, the transfer of this Note is registrable in the register of the Notes maintained by the Registrar upon surrender of this Note for registration of transfer, at the office or agency of the Company in any place where the
principal of and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder hereof or his

attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or
transferees. 
 As provided in the Indenture and subject to certain limitations herein and therein set forth, the Notes are exchangeable for
a like aggregate principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same. 
 No
service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Holder as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

Defined Terms. All terms used in this Note, which are defined in the Indenture and are not otherwise defined herein, shall have the
meanings assigned to them in the Indenture. 
 References to Interest. Any reference to interest on, or in respect of, the Notes in
the Indenture shall be deemed to include any interest payable to Holders of the Notes pursuant to the terms of that certain Registration Rights Agreement, dated December 9, 2014, among the Company and the several initial purchasers party
thereto. 
 Governing Law. The Indenture and the Notes shall be governed by and construed in accordance with the laws of the State of
New York without regard to conflicts of law principles of such State other than New York General Obligations Law Section 5-1401. 

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose.
