 2. Equity and Debt Offering. 

 

	 	(a)	In connection with an Equity Offering with Gross Proceeds of at least $400,000,000 but equal to or less than $700,000,000, Sprint HoldCo agrees to exercise its
preemptive rights under Section 3.5 of the Equityholders’ Agreement to commit to purchase New Securities (or Alternative New Securities) representing Sprint HoldCo’s Preemptive Right Pro Rata Share of the New Securities issued in such
Equity Offering. 

  

	 	(b)	In connection with an Equity Offering with Gross Proceeds of more than $700,000,000, (i) with respect to $700,000,000 of the Gross Proceeds of such Equity
Offering, Sprint HoldCo agrees to exercise its preemptive rights in accordance with Section 2(a) and (ii) with respect to any amount of Gross Proceeds of such Equity Offering in excess of $700,000,000, Sprint HoldCo may (but shall not be
obligated to) exercise all or any part of its preemptive rights under Section 3.5 of the Equityholders’ Agreement. In no event will Sprint HoldCo be obligated to commit to purchase New Securities (or Alternative New Securities) for an
aggregate purchase price of more than $700,000,000 multiplied by Sprint HoldCo’s Preemptive Right Pro Rata Share of the New Securities (or Alternative New Securities) issued in such Equity Offering. 

 

	 	(c)	Notwithstanding Section 3.5(g) of the Equityholders’ Agreement, the consummation of the transactions contemplated by Section 2(a) or Section 2(b)
will occur on the date of the consummation of the Equity Offering resulting in Gross Proceeds of at least $400,000,000. 

  

	 	(d)	Notwithstanding the foregoing, the obligation of Sprint HoldCo to consummate the transactions contemplated by Section 2(a) or Section 2(b) will be subject to
the simultaneous consummation of the remainder of such Equity Offering so as to result in Gross Proceeds of at least $400,000,000, the delivery of the closing deliverables set forth in Section 7 and the satisfaction of the closing conditions
set forth in Section 8. Sprint HoldCo’s obligations set forth in Section 2(a) and Section 2(b) shall (i) terminate upon the consummation of an Equity Offering pursuant to which Sprint HoldCo purchases New Securities (or
Alternative New Securities) in accordance with Section 2(a) or Section 2(b); and (ii) be suspended upon the occurrence and during the continuance of any payment default by any of the Clearwire Parties or their Subsidiaries under any
of their outstanding debt agreements or the MVNO Agreement. 

  

	 	(e)	In connection with the Equity Offering, the Sprint Parties shall be entitled to exercise all or any rights under Sections 2.13(j) and 3.5 of the Equityholders’
Agreement, and nothing in this Agreement shall alter or affect the rights of the Sprint Parties under the Equityholders’ Agreement (including the right to purchase Alternative New Securities in connection with any purchase pursuant to
Section 2(a) or Section 2(b)). 

  
 4 

	 	(f)	In connection with the Equity Offering, each of the Clearwire Parties shall provide to the Sprint Parties the same representations and warranties provided to, and the
obligations of Sprint HoldCo will be subject to all of the conditions of, the other participants in such Equity Offering and the rights of Sprint HoldCo under Section 3.5 of the Equityholders’ Agreement. In addition, Sprint HoldCo will
receive at least the same rights received by any other participant in such Equity Offering; provided that to the extent the Clearwire Parties pay a commitment fee to a participant in such Equity Offering then Sprint HoldCo will not be entitled to
receive such fee unless all other participants in such Equity Offering receive such fee. For the avoidance of doubt, if another participant in such Equity Offering has the right to terminate a commitment to purchase New Securities in such Equity
Offering, Sprint HoldCo’s right to terminate its commitment will apply only to such Equity Offering and will not terminate any other commitment of Sprint HoldCo to purchase New Securities (or Alternative New Securities) in any other Equity
Offering in accordance with the terms and conditions set forth in this Agreement. For the purposes of this Section 2(f), the term “participant in such Equity Offering” shall include any Person providing a commitment to purchase New
Securities in such Equity Offering (whether or not such purchase is conditioned on the purchase by any other Person or is actually consummated). 

  

	 	(g)	In connection with the Equity Offering resulting in Gross Proceeds of at least $400,000,000, Sprint HoldCo will execute a written consent to the Charter Amendment (the
“Consent”) and will agree to vote, at any meeting of stockholders and to the extent required by the rules of the Nasdaq Global Select Market, in favor of any payments by Clearwire of any customary fees required to be paid to an
unaffiliated third party in respect of a backstop commitment by such third party to purchase New Securities in such Equity Offering. 

  

	 	(h)	In connection with the consummation of the Equity Offering resulting in Gross Proceeds of at least $400,000,000, if requested by any managing underwriter or backstop
purchaser of such Equity Offering, each Sprint Party agrees to execute a customary lock-up agreement on the date of consummation of such Equity Offering, which shall include customary exceptions, with respect to the transfer by the Sprint Parties of
Class A Common Stock or Class B Common Stock, which lock-up agreement will provide for a lock-up period not to exceed ninety (90) days. 

  

	 	(i)	If Clearwire consummates the Equity Offering, Clearwire LLC shall use its commercially reasonable best efforts to consummate the Debt Offering at the earliest
practicable time thereafter.

Clearwire Parties hereby represents and warrants, jointly and severally, that as of the date hereof and as of the Purchase Date:

	 	(e)	for the avoidance of doubt, it was and remains the intention of Clearwire LLC, in approving and enacting Section 3.5 of the Operating Agreement, for the

therein on behalf of itself and its Subsidiaries; 

  

	 	(f)	each of the Transaction Agreements has been, or, in the case of the Note, will be on the Note Delivery Date, duly executed and delivered by each of the Clearwire
Parties party thereto and constitutes, or, in the case of the Note, will contitute on the Note Delivery Date, a legal, valid and binding obligation of each of the Clearwire Parties party thereto, enforceable against each of them in accordance with

	Confidential – Subject to Nondisclosure Obligations	  	3

 
invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Settlement Agreement will be reformed, construed and enforced in that
jurisdiction as if the invalid, illegal or unenforceable provision had never been contained in this Settlement Agreement and the parties to this Settlement Agreement will use their reasonable best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by that provision.

 FOR VALUE RECEIVED, the undersigned, CLEARWIRE COMMUNICATIONS LLC, a Delaware limited liability company
(the “Borrower”), hereby unconditionally promises to pay to the order of SPRINT SPECTRUM L.P., a Delaware limited partnership (the “Lender”), at its office at 6200 Sprint Parkway, Overland Park, Kansas 62251, or
such other location as to which the Lender shall have notified the Borrower in writing, in lawful money of the United States of America and in immediately available funds, (A) on January 2, 2013 (the “First Scheduled Maturity

times following the First Scheduled Maturity Date or, if earlier, the acceleration of the First Scheduled Maturity Date as provided herein, an additional 11.50% and (B) on January 2, 2014 (the “Second Scheduled Maturity
Date” and, together with the “First Scheduled Maturity Date, the “Scheduled Maturity Dates” and each, a “Scheduled Maturity Date”), (i) the principal sum of SEVENTY FIVE MILLION AND NO/100 DOLLARS
(U.S. $75,000,000.00), and (ii) interest on such principal amount outstanding from time to time after the date of this Promissory Note at a rate per annum equal to (x) 11.50% at all times during the period from the date of this Promissory
Note until such principal amount has been paid in full, plus (y) at all times during the existence of any Event of Default as provided herein, and at all times following the Second Scheduled Maturity Date or, if earlier, the acceleration of the
Second Scheduled Maturity Date as provided herein, an additional 11.50%. All such payments shall be made by the Borrower without reduction for any defense, claim, counterclaim, or any assertion or exercise of any right of recoupment or setoff
(except as expressly provided in Section 2 below). 
 1. Events of Default and Acceleration. Upon the occurrence and
at any time during the continuation of any of the following events or occurrences (each an “Event of Default”): 
 (a) any portion of the principal amounts due hereunder (the “Loan”) or any interest thereon shall not be paid, or shall not have been satisfied as provided herein, by the applicable
Scheduled Maturity Date; 
 (b) (i) there shall have occurred and be continuing any material breach by the
Borrower in respect of its obligations to the Lender under that certain 4G MVNO Agreement dated as of November 28, 2008, among the Borrower, the Lender, Comcast 

  
 1 

 
MVNO II, LLC, TWC Wireless, LLC, and BHN Spectrum Investment, as the same has heretofore and may hereafter be amended, restated, supplemented or otherwise modified from time to time (the
“4G MVNO Agreement”), including without limitation, as amended by that certain November 2011 Clearwire/Sprint Amendment to the 4G MVNO Agreement dated as of November         , 2011, between
the Borrower and the Lender (the “4G MVNO Sprint/Clearwire Amendment”)); or (ii) the 4G MVNO Agreement as between the Borrower and the Lender shall have been terminated or cancelled at any time prior to the Second Scheduled
Maturity Date; or 
 (c) (i) the Borrower shall commence any case, proceeding or other action (A) under any
existing or future law of any jurisdiction, domestic or foreign, relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking to have an order for relief entered with respect to it, or seeking to adjudicate it as bankrupt or
insolvent, or seeking reorganization, arrangement, adjustment, winding up, liquidation, dissolution, composition or other relief with respect to it or its debts, or (B) seeking appointment of a receiver, trustee, custodian, conservator or other
similar official for it or for all or any substantial part of its assets, or the Borrower shall make a general assignment for the benefit of its creditors; or (ii) there shall be commenced against the Borrower any case, proceeding or other
action of a nature referred to in clause (i) above that (x) results in the entry of an order for relief or any such adjudication or appointment or (y) remains undismissed or undischarged for a period of 60 days; or (iii) there
shall be commenced against the Borrower any case, proceeding or other action seeking issuance of a warrant of attachment, execution, distraint or similar process against all or any substantial part of its assets that results in the entry of an order
for any such relief that shall not have been vacated, discharged, or stayed or bonded pending appeal within 60 days from the entry thereof; or (iv) the Borrower shall take any action in furtherance of, or indicating its consent to, approval of,
or acquiescence in, any of the acts set forth in clause (i), (ii), or (iii) above; or (v) the Borrower shall generally not, or shall be unable to, or shall admit in writing its inability to, pay its debts as they become due; 

then, and in any such event, (A) if such event is an Event of Default specified in clause (ii) of paragraph (b) above, or in clause
(i) or (ii) of paragraph (c) above, the Loan (with accrued interest thereon) and all other amounts owing under this Promissory Note shall automatically and immediately become due and payable in full, without further action on the part
of the Lender, and (B) if such event is any other Event of Default, the Lender may declare the Loan (with accrued interest thereon) and all other amounts owing under this Promissory Note to be due and payable forthwith, whereupon the same shall
immediately become due and payable in full. 
 2. Satisfaction of Loan Amounts on the Scheduled Maturity Dates. The
Borrower and the Lender agree that, if and to the extent any portion of the Loan or any interest thereon or other amounts payable under this Promissory Note remain due and owing by the Borrower to the Lender on a Scheduled Maturity Date, and any
payments are then required to be paid by the Lender to the Borrower pursuant to Section 3.2 of Schedule 7.1 to the 4G MVNO Agreement (any such payments referred to herein as the “Sprint WBB Payments”), then the Lender,
at its sole option, shall be entitled to retain, offset and recoup any such Sprint WBB Payments against such payments then due from the Borrower to the Lender under this Promissory Note. Such action by the Lender shall be deemed to satisfy and
discharge the obligation of the Borrower to 

  
 2 

 
pay pursuant to this Promissory Note the corresponding amounts that have been so retained, offset and recouped by the Lender. 

3. Set-Off. In addition to any rights and remedies of the Lender provided herein or otherwise available to the Lender under
applicable law, the Lender and each of its affiliates shall have the right, upon the occurrence and during the continuation of any Event of Default, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the
extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at a Scheduled Maturity Date, by acceleration or otherwise), to offset and appropriate and apply against such amount any and all deposits
(general or special, time or demand, provisional or final), and any other credits, indebtedness payment obligations, property, or claims (including, without limitation, any Sprint WBB Payments), in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by the Lender or such affiliates to or for the credit or the account of the Borrower. The Lender agrees promptly to notify the Borrower after any such setoff and application made by the
Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application. 
 4. No
Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Lender, any right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right,
remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law. 
 5. Costs of Collection. The Borrower agrees to pay promptly
to the Lender on demand all reasonable costs and expenses of the Lender incurred or sustained in the collection of any portion of the Loan or any interest thereon or other amounts payable hereunder upon an occurrence of an Event of Default or other
enforcement of the Lender’s rights under this Promissory Note (including all reasonable fees and expenses of counsel for the Lender, whether incurred in any action or proceeding, including any bankruptcy, reorganization or other insolvency
proceeding, or otherwise). 
 6. Amendments, Waivers, etc. No amendment, modification or waiver of any provision of this
Promissory Note, nor consent to any departure by the Borrower or the Lender, as the case may be, from any provision of this Promissory Note, shall in any event be effective unless the same shall be in writing and signed by the Lender or the
Borrower, as the case may be, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which it is given. 
 7. Waivers of Presentment, etc. Without limiting the effect of Section 1 above, and to the extent not prohibited by applicable law, the Borrower hereby waives presentment for payment, demand,
notice of dishonor, notice of intent to accelerate and protest of this Promissory Note. 
 8. Successor and Assigns. The
provisions of this Promissory Note shall be binding upon and inure to the benefit of the Borrower and the Lender and their respective successors and 

  
 3 

 
assigns, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lender (and any attempted assignment or
transfer by the Borrower without such consent shall be null and void). 
 9. Governing Law. THIS PROMISSORY NOTE AND THE
RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS PROMISSORY NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PRINCIPLES THEREOF. 

10. Submission to Jurisdiction; Waivers. The Borrower hereby irrevocably and unconditionally: 

(a) submits for itself and its property in any legal action or proceeding relating to this Promissory Note or for recognition and
enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

 (b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or
hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same; 

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the Borrower, at its address set forth in the 4G MVNO Agreement, or such other address of which the Lender shall have been notified by the Borrower in writing; and 

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the
right to sue in any other jurisdiction. 
 11. Waiver of Jury Trial. THE BORROWER AND THE LENDER HEREBY IRREVOCABLY AND
UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS PROMISSORY NOTE AND FOR ANY COUNTERCLAIM IN RESPECT HEREOF.
