 $150,000,000 Senior Notes due April 1, 2010 
 OF 
 BGC PARTNERS, L.P. 
 Dated as of March 31, 2008 
 This GUARANTY (the or
this “Guaranty”) is entered into by the undersigned BGC PARTNERS, INC. (successor by merger of BGC Partners, LLC and eSpeed, Inc.), a Delaware corporation (the “Guarantor”), as of
March 31, 2008. 
 R E C I T A L S 
 A.    On the date hereof, BGC Partners, L.P. a Delaware limited partnership (the “Company”), entered
into the Note Purchase Agreement dated as of March 31, 2008 (the “Note Purchase Agreement”), with the Purchasers named in Schedule A thereto (together with their successors and assigns, the “Purchasers”).

 B.    Pursuant to the Note Purchase Agreement the Company is issuing and selling $150,000,000 in
aggregate principal amount of its Senior Notes due April 1, 2010 (the “Notes”) on the terms provided in the Note Purchase Agreement. The Purchasers and each and every other holder from time to time of the Notes are sometimes
hereinafter collectively referred to as the “Holders” and, individually, as a “Holder.” 
 C.    The Guarantor directly or indirectly owns all of the outstanding partnership interests of the Company. 
 D.    The Purchasers have required as a condition of their purchase of the Notes to be purchased by them that the Company cause the Guarantor to enter into this Guaranty as security for the Notes,
and the Company has agreed to cause the Guarantor to execute this Guaranty in order to induce the Purchasers to purchase the Notes and thereby benefit the Company and its Affiliates by providing funds to enable the Company to have funds available
for general partnership purposes. 
 E.    The Guarantor is desirous that the Purchasers enter into the
Note Purchase Agreement and purchase the Notes, and by doing so the Purchasers will be conferring substantial financial and other benefits on the Guarantor. 
 F.    Pursuant to a guaranty (the “CFLP Guaranty”), Cantor Fitzgerald, L.P., a Delaware limited partnership (“CFLP”), has also
unconditionally guaranteed the Notes. Pursuant to a 

			
	 BGC Partners, Inc.
	  	Guaranty

  
 
subsidiary guaranty (the “Subsidiary Guaranty”), Subsidiary Guarantors (as therein defined) may in the future unconditionally guarantee the
Notes. CFLP and the Subsidiary Guarantors, together with any other Person which shall become Guarantor of the Notes pursuant to the terms of the Note Purchase Agreement or this Guaranty, are sometimes hereinafter referred to individually as an
“other Guarantor” and collectively as the “other Guarantors”. 
 NOW,
THEREFORE, as required by the Note Purchase Agreement and in consideration of the premises and other good and valuable consideration, the receipt and sufficiency whereof are hereby acknowledged, the Guarantor hereby covenants and
agrees as follows: 
 SECTION 1.        DEFINITIONS. 

Capitalized terms used herein shall have the meanings set forth in Schedule A hereto unless herein defined or the context shall
otherwise require. 
 SECTION 2.        GUARANTY OF
NOTES AND NOTE PURCHASE AGREEMENT. 
 The
Guarantor hereby irrevocably, absolutely and unconditionally guarantees to the Holders: (a) the full and prompt payment of the principal of, premium, if any, and interest on the Notes from time to time outstanding, as and when such payments
shall become due and payable, whether by lapse of time, upon redemption or prepayment, by extension or by acceleration or declaration or otherwise (including (to the extent legally enforceable) interest due on overdue payments of principal, premium,
if any, or interest at the rate set forth in the Notes and interest accruing at the then applicable rate provided in the Notes after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding,
relating to the Company, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) in Federal or other immediately available funds of the United States of America which at the time of payment or demand therefor
shall be legal tender for the payment of public and private debts, (b) the full and prompt performance and observance by the Company of each and all of the obligations, covenants and agreements required to be performed or owed by the Company
under the terms of the Notes and the Note Purchase Agreement and (c) the full and prompt payment, upon demand by any Holder, of all costs and expenses, legal or otherwise (including attorneys’ fees), if any, as shall have been expended or
incurred in the protection or enforcement of any rights, privileges or liabilities in favor of the Holders under or in respect of the Notes, the Note Purchase Agreement or under this Guaranty or in any consultation or action in connection therewith
or herewith and in each and every case irrespective of the validity, regularity, or enforcement of any of the Notes or Note Purchase Agreement or any of the terms thereof or any other like circumstance or circumstances. 
 SECTION 3.        GUARANTY OF PAYMENT
AND PERFORMANCE. 
 This is a guarantee of payment and performance and the Guarantor hereby
waives, to the fullest extent permitted by law, any right to require that any action on or in respect of any Note, the Note Purchase Agreement or any other Guaranty be brought against the Company, CFLP, any Subsidiary Guarantor or any other Person
or that resort be had to any direct or

	  	Guaranty

  
 
indirect security for the Notes or for this Guaranty or any other remedy. Any Holder may, at its option, proceed hereunder against the Guarantor in the first
instance to collect monies when due, the payment of which is guaranteed hereby, without first proceeding against the Company or any other Person and without first resorting to any direct or indirect security for the Notes or for this Guaranty or any
other remedy. The liability of the Guarantor hereunder shall in no way be affected or impaired by any acceptance by any Holder of any direct or indirect security for, or other guaranties of, any Debt, liability or obligation of the Company or any
other Person to any Holder or by any failure, delay, neglect or omission by any Holder to realize upon or protect any such guarantees, Debt, liability or obligation or any notes or other instruments evidencing the same or any direct or indirect
security therefor or by any approval, consent, waiver, or other action taken, or omitted to be taken by any such Holder. 
 SECTION 4.        GENERAL PROVISIONS RELATING TO THE GUARANTY. 
 (a)    The Guarantor hereby consents and agrees that any Holder or Holders from time to time, with or without any
further notice to or assent from the other Guarantors may, without in any manner affecting the liability of the Guarantor under this Guaranty, and upon such terms and conditions as any such Holder or Holders may deem advisable: 
 (1)    extend in whole or in part (by renewal or otherwise), modify, change, compromise, release or
extend the duration of the time for the performance or payment of any Debt, liability or obligation of the Company or of any other Person secondarily or otherwise liable for any Debt, liability or obligations of the Company on the Notes, or waive
any Default with respect thereto, or waive, modify, amend or change any provision of any other agreement or this Guaranty; or 
 (2)    sell, release, surrender, modify, impair, exchange or substitute any and all property, of any nature and from whomsoever received, held by, or for the benefit of, any such Holder as direct
or indirect security for the payment or performance of any Debt, liability or obligation of the Company or of any other Person secondarily or otherwise liable for any Debt, liability or obligation of the Company on the Notes; or 
 (3)    settle, adjust or compromise any claim of the Company against any other Person secondarily or
otherwise liable for any Debt, liability or obligation of the Company on the Notes. 
 The Guarantor hereby ratifies and
confirms any such extension, renewal, change, sale, release, waiver, surrender, exchange, modification, amendment, impairment, substitution, settlement, adjustment or compromise and that the same shall be binding upon it, and hereby waives, to the
fullest extent permitted by law, any and all defenses, counterclaims or offsets which it might or could have by reason thereof, it being understood that the Guarantor shall at all times be bound by this Guaranty and remain liable hereunder.

by action at law, suit in equity or otherwise, shall not be subject to any reduction, limitation, impairment or termination (other than by payment in full of the Notes and the obligations of the Company under the Note Purchase Agreement), whether by
reason of any claim of any character whatsoever or otherwise and shall not be subject to any defense, set-off, counterclaim (other than any compulsory counterclaim), recoupment or termination whatsoever.

and shall remain in full force and effect until the entire principal, interest and premium, if any, on the Notes and all other sums due pursuant to Section 2 shall have been paid and such obligations shall not be affected, modified or
impaired upon the happening from time to time of any event, including without limitation any of the following, whether or not with notice to or the consent of the Guarantor:

payment thereof in Federal or other immediately available funds, or (ii) the Company or any other Person might have to the performance or observance of any of the provisions of the Notes, the Note Purchase Agreement, this Guaranty, any other
Guaranty or any other agreement, whether through the satisfaction or purported satisfaction by the Company, the Guarantor, any other Guarantor or any other Person of its debts due to any cause such as bankruptcy, insolvency, receivership, merger,
consolidation, reorganization, dissolution, liquidation, winding-up or otherwise, other than the defense of indefeasible payment in full in cash of the Notes; or 
 (13)    any act or failure to act with regard to the Notes, the Note Purchase Agreement, this
Guaranty, any other Guaranty or any other agreement or anything which might vary the risk of the Guarantor, any other Guarantor or any other Person; or

the obligations of the Guarantor, any other Guarantor or other Person under this Guaranty, any other Guaranty or any other agreement, other than the defense of indefeasible payment in full in cash of the Notes; 
 provided that the specific enumeration of the above-mentioned acts, failures or omissions shall not be deemed to exclude any other acts, failures
or omissions, though not specifically mentioned above, it being the purpose and intent of this Guaranty and the parties hereto that the obligations of the Guarantor hereunder shall be absolute and unconditional and shall not be discharged,

impaired or varied except by the payment of the principal of, premium, if any, and interest on the Notes in accordance with their respective terms whenever
the same shall become due and payable as in the Notes provided and all other sums due and payable under the Note Purchase Agreement, at the place specified in and all in the manner and with the effect provided in the Notes and the Note Purchase
Agreement, as each may be amended or modified from time to time. Without limiting the foregoing, it is understood that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Company shall
default under or in respect of the terms of the Notes or the Note Purchase Agreement and that notwithstanding recovery hereunder for or in respect of any given default or defaults by the Company under the Notes or the Note Purchase Agreement, this
Guaranty shall remain in full force and effect and shall apply to each and every subsequent default. 
 (d)    All rights of any Holder may be transferred or assigned at any time and shall be considered to be transferred or assigned at any time or from time to time upon the transfer of any Note whether with or without the
consent of or notice to the Guarantor under this Guaranty or to the Company. 
 (e)    To the extent of
any payments made under this Guaranty, the Guarantor shall be subrogated to the rights of the Holder upon whose Notes such payment was made, but the Guarantor covenants and agrees that such right of subrogation shall be subordinate in right of
payment to the prior indefeasible final payment in cash in full of all amounts due and owing by the Company with respect to the Notes and the Note Purchase Agreement and by the Guarantor under this Guaranty, and the Guarantor shall not take any
action to enforce such right of subrogation, and the Guarantor shall not accept any payment in respect of such right of subrogation, until all amounts due and owing by the Company under or in respect of the Notes and the Note Purchase Agreement and
all amounts due and owing by the Guarantor hereunder have indefeasibly been finally paid in cash in full. If any amount shall be paid to the Guarantor in violation of the preceding sentence at any time prior to the later of the indefeasible payment
in cash in full of the Notes and all other amounts payable under the Notes, the Note Purchase Agreement and this Guaranty, such amount shall be held in trust for the benefit of the Holders and shall forthwith be paid to the Holders to be credited
and applied to the amounts due or to become due with respect to the Notes and all other amounts payable under the Note Purchase Agreement and this Guaranty, whether matured or unmatured. The Guarantor acknowledges that it has received direct and
indirect benefits from the financing arrangements contemplated by the Note Purchase Agreement and that the waiver set forth in this paragraph (e) is knowingly made as a result of the receipt of such benefits. 
 (f)    The Guarantor agrees that to the extent the Company, any other Guarantors or any other Person makes any
payment on any Note, which payment or any part thereof is subsequently invalidated, voided, declared to be fraudulent or preferential, set aside, recovered, rescinded or is required to be retained by or repaid to a trustee, receiver, or any other
Person under any bankruptcy code, common law, or equitable cause, then and to the extent of such payment, the obligation or the part thereof intended to be satisfied shall be revived and continued in full force and effect with respect to the
Guarantor’s obligations hereunder, as if said payment had not been made. The liability of the Guarantor hereunder shall not be reduced or discharged, in whole or in part, by any payment to any Holder from any source that is thereafter paid,

of the properties owned by it or the transaction of its business makes such registration necessary. BGCFI and its Affiliates possess all of the licenses and registrations from and with any governmental agency or instrumentality, or any securities or
commodities exchange or self-regulatory organization, necessary or appropriate for the conduct of its business, as such business is presently conducted; and

 Section 5.9.    Taxes.  The Guarantor and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction and that are Material, and have paid all taxes shown to
be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent,
except for any taxes and assessments (a) the amount of which is not individually or in the aggregate Material or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and
with respect to which the Guarantor or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Guarantor knows of no basis for any other tax or assessment that could reasonably be expected to have a Material
Adverse Effect. The charges, accruals and reserves on the books of the Guarantor and its Subsidiaries in respect of federal, state or other taxes for all fiscal periods are adequate. The federal income tax liabilities of eSpeed, Inc., the
predecessor to the Guarantor and its Subsidiaries have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all Fiscal Years up to and including the Fiscal Year ended December 31, 2003.

 Section 5.10.    Title to Property; Leases.  The Guarantor and its Subsidiaries
have good and sufficient title to their respective properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to
have been acquired by the Guarantor or any Subsidiary after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Guaranty. All leases that individually or in
the aggregate are Material are valid and subsisting and are in full force and effect in all material respects. 
 Section 5.11.    Licenses, Permits, Etc.    (a) The Guarantor and its Subsidiaries own or possess all licenses, permits, franchises, authorizations, patents, copyrights, proprietary
software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of others. 
 (b)    To the best knowledge of the Guarantor, no product of the Guarantor or any of its Subsidiaries infringes in any respect any license, permit, franchise, authorization,
patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person, except as would not individually or in the aggregate have a Material Adverse Effect. 
 (c)    To the best knowledge of the Guarantor, there is no Material violation by any Person of any right of the
Guarantor or any of its Subsidiaries with respect to any patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the Guarantor or any of its Subsidiaries. 
 Section 5.12.    Compliance with ERISA.  (a) The Guarantor and each ERISA Affiliate have

	 BGC Partners, Inc.
	  	Guaranty

  
 
any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in
Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Guarantor or any ERISA Affiliate, or in the imposition of any Lien on
any of the rights, properties or assets of the Guarantor or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code or Section 4068 of
ERISA, other than such liabilities or Liens as would not be individually or in the aggregate Material. 
 (b)    The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the
actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term “benefit
liabilities” has the meaning specified in Section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in Section 3 of ERISA. 
 (c)    The Guarantor and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to
contingent withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material. 
 (d)    The expected post retirement benefit obligation (determined as of the last day of the Guarantor’s most recently ended Fiscal Year in accordance with Financial
Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by Section 4980B of the Code) of the Guarantor and its Subsidiaries is not Material. 
 (e)    The execution and delivery of this Guaranty will not involve any transaction that is subject to the
prohibitions of Section 406(a)(i) of ERISA or in connection with which a tax could be imposed pursuant to Section 4975(c)(1)(A)-(D) of the Code. The representation by the Guarantor in the first sentence of this Section 5.12(e)

Purchaser. 
 Section 5.13.    Private Offering by the Guarantor.  Neither the
Guarantor nor anyone acting on its behalf has offered the Notes, this Guaranty or any similar Securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other
than the Purchasers, each of which has been offered the Notes at a private sale for investment. Neither the Guarantor nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the
registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction. 
 Section 5.14.    Margin Regulations.  Margin stock does not constitute more than 2% of the value of the consolidated assets of the Guarantor and its
Subsidiaries and the Guarantor does not have any present intention that margin stock will constitute more than 2% of the value of such

with respect to any Debt of the Guarantor or any Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Debt to become due and payable before its stated maturity or before its
regularly scheduled dates of payment. 
 (b)    Except as disclosed in Schedule 5.15, neither
the Guarantor nor any Subsidiary has agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by
Section 8.3. 
 (c)    Neither the Guarantor nor any Subsidiary is a party to, or otherwise
subject to any provision contained in, any instrument evidencing Debt of the Guarantor or such Subsidiary, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational document) which
limits the amount of, or otherwise imposes restrictions on the incurring of, Debt of the Guarantor or any Subsidiary, except as specifically indicated in Schedule 5.15. 
 Section 5.16.    Foreign Assets Control Regulations, Etc.  (a) Neither the sale of the
Notes nor the use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto.

payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper
advantage, in violation of the United States Foreign Corrupt Practices Act of 1977, as amended, assuming in all cases that such Act applies to the Guarantor.

raising any claim against the Guarantor or any of its Subsidiaries or any of their respective real properties now or formerly owned, leased or operated by any of them or other assets, alleging any damage to the environment or violation of any
Environmental Laws, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect.

their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in
effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the
case of entities of established reputations engaged in the same or a similar business and similarly situated and the failure of which to so maintain would have a Material Adverse Effect. 
 Section 7.3.    Maintenance of Properties.  The Guarantor will, and will cause each of its
Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be

Subsidiary; provided that neither the Guarantor nor any Subsidiary need pay any such tax or assessment or claims or file any such tax return if (a) the amount, applicability or validity thereof is contested by the Guarantor or such
Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Guarantor or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Guarantor or such Subsidiary or (b) the
nonpayment of all such taxes, assessments and claims in the aggregate or failure to file such tax returns could not reasonably be expected to have a Material Adverse Effect. 
 Section 7.5.    Legal Existence, Etc.  Subject to Section 8.4, the Guarantor will at all times preserve and keep in full force and effect its
existence as a limited partnership and its status as not being taxable as a corporation for U.S. federal income tax purposes. Subject to Sections 8.4 and 8.5, the Guarantor will at all times preserve and keep in full force
and effect the legal existence of each of its Subsidiaries (unless merged into the Guarantor or a Wholly-owned Subsidiary) and all rights and franchises of the Guarantor and its Subsidiaries unless, in the good faith judgment of the Guarantor, the

 Section 7.6.    Notes to Rank Pari Passu.  The obligations under this Guaranty of the Guarantor
are and at all times shall rank at least pari passu in right of payment with all other present and future unsecured Senior Debt (actual or contingent) of the Guarantor.

Guarantor by application of Section 8.5(iii)(2)) from the Subsidiary Guaranty to which it is a party pursuant to the written request of the Guarantor, provided that (i) either (1) such Subsidiary Guarantor has been
released and discharged as an obligor and/or guarantor under and in respect of all Priority Debt or (2) the liability of such Subsidiary Guarantor as obligor and/or guarantor in respect of all Priority Debt is at the time of discharge and

disposition of any assets to be applied pursuant to this clause (B) to the offer of prepayment of Senior Debt of the Guarantor other than the Notes may

decline any such offer of prepayment shall be deemed to be an election by such holder to decline such prepayment; and

Purchase Agreement, excepting only that such prepayment shall be at par without payment of Make-Whole Amount or other premium.

Subsidiary to enter into, directly or indirectly, any Material transaction or Material group of related transactions (including without limitation the purchase, lease, sale or exchange of properties of any kind or the rendering of any service) with
any Affiliate (other than the Guarantor or a Subsidiary), except upon fair and reasonable terms no less favorable to the Guarantor or such Subsidiary, as the case may be, than it would obtain in a comparable arm’s-length transaction with a
Person not an Affiliate of the Guarantor or such Subsidiary and in the case of any transaction or transactions with any Affiliate other than an Unrestricted Subsidiary, in the ordinary course of the Guarantor’s or such Subsidiary’s
business; provided that management or other fees, compensation, employee benefit arrangement or indemnification programs, plans or arrangements pertaining to limited or general partners of the Guarantor or any of its Subsidiaries entered into

not to be in violation of this Section 8.6. 
 Section 8.7.    Line of
Business.    The Guarantor will not and will not permit any Subsidiary to engage in any business if, as a result, the general nature of the business in which the Guarantor and its Subsidiaries, taken as a whole, would then be

 (a)    Solicitation.  The Guarantor will provide each holder of the Notes (irrespective of the
amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or
consent in respect of any of the provisions hereof. The Guarantor will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 11 to each holder of outstanding
Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes. 
 (b)    Payment.  The Guarantor will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or
grant any security or provide other credit support, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof unless such
remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or
amendment. 
 Section 11.3.    Binding Effect, Etc.  Any amendment or waiver
consented to as provided in this Section 11 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Guarantor without regard to whether such Note has been marked to indicate
such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the
Guarantor and the holder of any Note nor any delay in exercising any rights hereunder shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Guaranty” and references thereto shall mean this
Guaranty as it may from time to time be amended or supplemented. 
 Section 11.4.    Notes Held
by Guarantor, Etc.    Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent
to be given under this Guaranty or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes
directly or indirectly owned by the Guarantor or any of its Affiliates shall be deemed not to be outstanding. 
 SECTION 12.        NOTICES. 
 All
notices and communications provided for hereunder shall be in writing and sent (a) by telefacsimile if the sender on the same day sends a confirming copy of such notice by a

recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or
(c) by a recognized overnight delivery service (with charges prepaid). Any such notice must be sent: 
 (i)    if to any Purchaser or its nominee, to such Purchaser or nominee at the address specified for such communications in Schedule A to the Note Purchase Agreement, or at such other address as such Purchaser or
nominee shall have specified to the Guarantor or the Company in writing, 
 (ii)    if to
any other holder of any Note, to such holder at such address as such other holder shall have specified to the Guarantor or the Company in writing, or 
 (iii)    if to the Guarantor, to the Guarantor at its address set forth at the beginning hereof to the attention of General Counsel, with a copy to CFLP at 499 Park
Avenue, New York, NY 10022, Attention: General Counsel, or at such other address as the Guarantor or CFLP, as the case may be, shall have specified to the holder of each Note in writing. 
 Notices under this Section 12 will be deemed given only when actually received. 
 SECTION 13.        REPRODUCTION OF DOCUMENTS. 
 This Guaranty and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any
Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic,
electronic, digital or other similar process and such Purchaser may destroy any original document so reproduced. The Guarantor agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in
evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement,
facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 13 shall not prohibit the Guarantor or any other holder of Notes from contesting any such reproduction to the same extent that
it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. 
 SECTION 14.        CONFIDENTIAL INFORMATION. 
 The terms and provisions of Section 20 of the Note Purchase Agreement are incorporated herein by reference mutis mutandi.

 SECTION 15.        MISCELLANEOUS. 
 Section 15.1.    Successors and Assigns.    All covenants and other agreements contained in this Guaranty by or on behalf of any of the parties hereto bind and inure to the benefit of
their respective successors and assigns (including, without limitation, any permitted subsequent Holder) whether so expressed or not. 
 Section 15.2.    Payments Due on Non-Business Days.    Anything in this Guaranty to the contrary notwithstanding (but without limiting the requirement in
Section 8.4 of the Note Purchase Agreement that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date
other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of
any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next
succeeding Business Day. 
 Section 15.3.    Accounting Terms.    All
accounting terms used herein which are not expressly defined in this Guaranty or the Note Purchase Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all
computations made pursuant to this Guaranty shall be made in accordance with GAAP and (ii) all financial statements shall be prepared in accordance with GAAP. 
 Section 15.4.    Severability.    Any provision of this Guaranty that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not
invalidate or render unenforceable such provision in any other jurisdiction. 
 Section 15.5.    Construction, Etc.    Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained
herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such
Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 
 For the avoidance of doubt, all Schedules and Exhibits attached to this Guaranty shall be deemed to be a part hereof. 
 Section 15.6.    Counterparts.    This Guaranty may be executed in any number of counterparts, each of which shall be an original but all of which together shall
constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

 Section 15.7.    Governing Law.  This Guaranty shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the law of the State of New
York, excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. 
 Section 15.8.    Jurisdiction and Process; Waiver of Jury
Trial.    (a)    The Guarantor irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action
or proceeding arising out of or relating to this Guaranty. To the fullest extent permitted by applicable law, the Guarantor irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to
the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any
such court has been brought in an inconvenient forum. 
 (b)    The Guarantor consents to process being
served by or on behalf of any holder of Notes in any suit, action or proceeding of the nature referred to in Section 15.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage
prepaid, return receipt requested, to it at its address specified in Section 12 or at such other address of which such holder shall then have been notified pursuant to said Section. The Guarantor agrees that such service upon receipt
(i) shall be deemed in every respect effective service of process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and
personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service. 
 (c)    Nothing in this Section 15.8 shall affect the right of any Holder to serve process in any manner
permitted by law, or limit any right that the holders of any of the Notes may have to bring proceedings against the Guarantor in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in
any other jurisdiction. 
 (d)    THE PARTIES HERETO
HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH
RESPECT TO THIS GUARANTY OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION
HEREWITH OR THEREWITH. 
 Section 15.9.    Indemnity.    To the fullest extent of applicable law, the Guarantor shall indemnify and save each holder of the Notes harmless from and against any losses which may arise
in connection with any of the obligations hereby guaranteed being or becoming for any reason whatsoever in whole or in part void, voidable, contrary to law, invalid, ineffective or otherwise unenforceable by the holder of the Notes or any of them in
accordance with its terms (all of the foregoing collectively, an “Indemnifiable Circumstance”). For greater certainty, these losses shall include without limitation all obligations hereby guaranteed which would have been payable by
the Company but for the existence of an Indemnifiable Circumstance; provided, that the extent of the Guarantor’s aggregate liability under this Section 15.9 shall not at any time
