          (a) Clearwire on the date hereof is, and prior to Closing, Clearwire will cause NewCo to be,
and as of the Closing NewCo will be, a corporation duly organized, validly existing and in good

          (b) All corporate action on the part of Clearwire and NewCo, and their respective officers,

constitutes the valid and legally binding obligation of Clearwire, and upon Closing will constitute

          (e) No SEC Document contains any untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading, except to the

4

 

extent that any such information contained in such filing has been revised, amended,
supplemented or superseded by a later filing with the SEC.

     7. Representations and Warranties of Subscriber. Subscriber represents and warrants
as follows:

          (a) Subscriber is acquiring the Stock for its own account for investment, not for the interest
of any other person, and not with a view to the resale of the Stock to others.

          (b) Subscriber understands that the Stock will not be registered under the Securities Act of
1933, as amended (the “Securities Act”), or the securities laws of any state, and that Subscriber
has no right to require such registration except as set forth in the Joinder.

          (c) Subscriber has such knowledge and experience in financial and business matters that it is
capable of seeking out and evaluating the information relevant to evaluating NewCo, the proposed
activities thereof, and the merits and risks of the prospective investment, and to make an informed
investment decision in connection therewith.

          (d) Subscriber is validly existing and in good standing under the laws of the jurisdiction of
its organization, has all requisite power and authority to subscribe and perform its obligations
hereunder, has taken all limited liability company action necessary to purchase the Stock pursuant
to this Agreement, and was not organized for the purpose of acquiring the Stock unless all of its
equity owners qualify as accredited investors within the meaning of Regulation D promulgated under
the Securities Act.

          (e) Subscriber warrants that Subscriber is an “accredited investor” within the meaning of Rule
501(a) of Regulation D promulgated under the Securities Act.

          (f) Subscriber acknowledges that Subscriber has been provided with all other materials and
information it has requested, to the extent possessed or obtainable by Clearwire. Subscriber has
had the opportunity to ask questions of, and receive answers from, Clearwire, Sprint and their
respective officers, employees, and representatives concerning NewCo and the transactions
contemplated by the Transaction Agreement.

          (g) Except for the representations and warranties of Clearwire and NewCo in this Agreement, in
making a decision to acquire the Stock, Subscriber has relied solely upon its own counsel and
independent investigations made by Subscriber. Subscriber is not relying on Clearwire with respect
to legal, tax and other economic considerations involved in this transaction.

          (h) All requisite action on the part of Subscriber, its officers, managers and members
necessary for the authorization, execution and delivery of this Agreement has been taken, and this
Agreement constitutes the valid and legally binding obligations of Subscriber, enforceable in
accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting enforcement of
creditors’ rights generally, and (ii) as limited by laws and principles relating to the
availability of specific performance, injunctive relief, or other equitable remedies.

5

 

     8. Restricted Securities. Subscriber understands that the Stock has not been, and
will not, except in accordance with the Joinder, be registered under the Securities Act, by reason
of a specific exemption from the registration provisions of the Securities Act which depends upon,
among other things, the bona fide nature of the investment intent and the accuracy of Subscriber’s
representations as expressed herein. Subscriber understands that the shares of Stock are
“restricted securities” under applicable U.S. federal and state securities laws and that, pursuant
to these laws, Subscriber must hold the Stock indefinitely unless the Stock is registered with the
Securities and Exchange Commission and qualified by state authorities, or an exemption from such
registration and qualification requirements is available. Subscriber acknowledges that NewCo will
have no obligation to register or qualify the Stock for resale except as set forth in the Joinder.
Subscriber further acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not limited to, the time
and manner of sale, the holding period for the Stock, and on requirements relating to NewCo which
are outside of Subscriber’s control, and which NewCo is under no obligation and may not be able to
satisfy. Subscriber also acknowledges that the certificates representing the Stock shall bear the
restrictive legends required under applicable federal and state securities laws; provided that if
Subscriber delivers to NewCo an opinion of counsel to NewCo, in a form and substance reasonably
acceptable to NewCo, that transfers of some or all of the Stock held by Subscriber do not require
registration under the applicable federal and securities laws, NewCo will promptly deliver new
certificates for such shares without such legends.

     9. Indemnification. Subscriber, on one hand, and Clearwire, prior to the Closing of
the transactions contemplated by the Transaction Agreement, and thereafter, NewCo, on the other
hand, will indemnify and hold each other, as well as their respective officers, directors,
stockholders, members, agents, attorneys and affiliates (the “Indemnified Parties”) harmless from
and against, and will reimburse the Indemnified Parties for, any and all losses, damages, debts,
liabilities, obligations, judgments, orders, awards, writs, injunctions, decrees, fines, penalties,
taxes, costs or expenses (including but not limited to any reasonable legal and accounting fees and
expenses) (“Losses”) arising out of or based upon any false representation or warranty or breach or
failure by Clearwire or NewCo, on one hand, or Subscriber, on the other hand, respectively, to
comply with any covenant or agreement made by Subscriber, on one hand, or Clearwire or NewCo, on
the other hand, as the case may be, in this Agreement.

     10. Termination. This Agreement shall terminate: (a) automatically upon the
termination of the Transaction Agreement; (b) upon the mutual written agreement of the Parties; (c)
upon notice by Subscriber to Clearwire or NewCo if the Closing has not occurred by the first
anniversary of the Effective Date; and (d) upon notice by Subscriber, on one hand, or Clearwire or
NewCo, on the other hand, if the conditions to Closing are incapable of being satisfied and have
not been waived by the applicable Party.

     11. MFN. For so long as any member of Subscriber is a director of NewCo (such
director shall be referred to as a “Subscriber Designee”), NewCo shall promptly provide Subscriber
Designee with a copy of any arrangement, understanding or agreement (each, a “Supplemental
Agreement”) (or, in the case of any oral Supplemental Agreement, a detailed summary of the
material terms thereof) entered into with or on behalf of any other Founding Stockholder (as such
term is defined in NewCo’s Certificate of Incorporation), board member, board observer, or officer
of NewCo containing a waiver, supplement to or modification of any

6

 

of the provisions regarding the allocation of corporate opportunities, competing with the
business of NewCo and its subsidiaries or any other matters covered by Article 11 of NewCo’s
Certificate of Incorporation (including, any successor provision thereto or any other provisions
contained in NewCo’s Certificate of Incorporation from time to time covering such matters). At the
option of Subscriber exercisable by Subscriber in its sole discretion upon notice to NewCo by
Subscriber, and without any further action on the part of any Founding Stockholder described in
clause (8) of the definition thereof contained in NewCo’s Certificate of Incorporation (including
any successor provision thereto covering the matters set forth therein) (each a “Subscriber
Founding Member”) or NewCo, any Subscriber Designee or Subscriber Founding Members shall be
entitled to the benefit of and subject to the requirements of any provisions in any such
Supplemental Agreements regarding the allocation of corporate opportunities, competing with the
business of NewCo and its subsidiaries or any other matters covered by Article 11 of NewCo’s
Certificate of Incorporation (including, any successor provision thereto or any other provisions
contained in NewCo’s Certificate of Incorporation from time to time covering such matters) that are
more favorable, as a whole, to the Persons party thereto than are set forth in NewCo’s Certificate
of Incorporation or pursuant to any other Supplemental Agreements to which Subscriber Designee or
Subscriber Founding Member may be subject from time to time.

     12. Tag-Along and Joinder. Subscriber shall have the same “Tag-Along Rights” (and any
similar rights) and benefits as a “Tag-Along Equity Holder” for all purposes of the Equityholders’
Agreement, attached as an exhibit to the Transaction Agreement; provided that, notwithstanding
anything to the contrary contained herein or in the Equityholders’ Agreement, no amendment, waiver,
termination or modification of such rights that adversely affect Subscriber shall be effective on
or binding upon Subscriber without Subscriber’s prior consent thereto. At the Closing the
Investors and Sprint will execute the Joinder in the form attached hereto as Exhibit A.

     13. Miscellaneous.

          (a) Notices. All notices and other communications given or made pursuant to this
Agreement shall be in writing and shall be deemed effectively given: (i) upon personal delivery to
the party to be notified (with evidence of delivery and postage or other fees paid), (ii) when sent

recipient, and if not sent during normal business hours, then on the next business day, (iii) five
(5) days after having been sent by registered or certified mail, return receipt requested, postage
prepaid, or (iv) one (1) day after deposit with a nationally recognized overnight courier,
specifying next day delivery, with written verification of receipt. All communications shall be
sent to the respective Parties at their addresses as set forth on below, as the case may be, or to
such facsimile number or address as subsequently modified by written notice given in accordance
with this Section. NewCo will promptly deliver to Subscriber all amendments, waivers, terminations
or modifications of the Transaction Agreement, the Equityholders Agreement, Operating Agreement,
the Registration Rights Agreement and the charter and bylaws of NewCo attached to the Transaction
Agreement and each other document provided to Subscriber in connection with the transaction
contemplated hereby and the Transaction Agreement.

          (b) Governing Law; Jurisdiction. This Agreement will be governed by and construed and
enforced in accordance with the internal Laws of the State of Delaware without reference to its
choice of law rules. Any proceeding seeking to enforce any provision of, or based on any matter
arising out of or in connection with, this Agreement may only be brought in the courts of the State
of Delaware or the federal courts located in the State of Delaware, and each of the Parties
consents to the jurisdiction of the courts (and of the appropriate appellate courts therefrom) in
any proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that
it may now or hereafter have to the laying of the venue of any proceeding in any court or that any
proceeding that is brought in any court has been brought in an inconvenient forum. Process in any
proceeding may be served on any party anywhere in the world, whether within or without the
jurisdiction of the court.

          (c) Entire Agreement. This Agreement constitutes the entire agreement between the
Parties hereto with respect to the subject matter hereof and may be amended only by a writing
executed by Subscriber and Clearwire.

          (d) No Brokers. Subscriber represents and warrants that Subscriber has taken no
action that would give rise to any claim by any person for brokerage commissions, finders’ fees or
the like relating to this Agreement or the transactions contemplated hereby, and Subscriber agrees
to hold Clearwire and NewCo harmless with respect to any claim for compensation by any person for
such services.

          (e) Successors and Assigns. Neither Clearwire nor Subscriber shall have any right to
assign or otherwise transfer their respective rights under this Agreement without the prior written
consent of the other Party except that (i) Clearwire hereby consents to any assignment by
Subscriber of its rights and obligations to any of its Affiliates (as defined in the Transaction
Agreement), including without limitation, Trilogy Equity Partners, LLC, and (ii) Subscriber hereby
consents to the assignment by Clearwire of all of its rights and obligations under this Agreement
to NewCo, upon the closing of the transactions contemplated by the Transaction Agreement. Subject
to the foregoing, any attempted assignment or transfer without such prior written consent shall be
null and void.

          (f) Counterparts. This Agreement may be executed in multiple counterparts, each of
which shall be enforceable against the party actually executing such counterpart and all of which
together shall constitute one instrument. Facsimile signatures are acceptable as originals.

PATENT TRANSFER

     Section 2.01 Patent Transfer to NewCo. Sampras hereby assigns and will cause each Sampras
Group member to assign to the NewCo Group member designated by NewCo, subject to any rights of
Third Parties existing on the Effective Date, all the Sampras Group’s right, title and interest in
the Assigned Patents. To the best of Sampras’ knowledge, there are no Third Party rights or claims
in the Assigned Patents. In the event there is a material Third Party right in any Assigned
Patent, Sampras will give Newco reasonable notice of such right. Following execution of the
assignment, NewCo shall assume all responsibility and expenses associated with processing and
pursuing the Assigned Patents.

     Section 2.02 Exhibit A. To the best of Sampras’ knowledge, Exhibit A is a complete
list of all Assigned Patents. Sampras shall, from time to time, revise Exhibit A to
include all Assigned Patents that were not included on Exhibit A as of the Effective
Date, and shall act reasonably in considering any written request by Newco for inclusion of a
Sampras Patent which NewCo has reason to assert is an Assigned Patent.

     Section 2.03 Cooperation.

     (a) Sampras will reasonably cooperate with NewCo, and will cause all applicable Sampras Group
members, agents and counsel to reasonably cooperate with NewCo, at NewCo’s expense with respect to
Third Party costs, in connection with (i) the preparation, filing, prosecution, maintenance and
defense of the NewCo Patents, and (ii) any suit for infringement of the NewCo Patents brought by
any NewCo Group member against a Third Party, and (iii) executing any applicable documents
requested by NewCo to perfect ownership and register patent assignments with any patent office.

     (b) NewCo will reasonably cooperate with Sampras, and will cause all NewCo Group members,
agents and counsel to reasonably cooperate with Sampras, at Sampras’s expense with respect to Third
Party costs, in connection with (i) the preparation, filing, prosecution, maintenance and defense
of the Sampras Patents, and (ii) any suit for infringement of the Sampras Patents brought by a
Sampras Group member against a Third Party, and (iii) executing

3

 

any applicable documents requested
by Sampras to perfect ownership and register patent assignments with any patent office.

     (c) Each party may make available to the other party, on written request, that party’s
patents, for use by the requesting party in defending against a Third Party patent infringement
claim. The party receiving such a request will use commercially reasonable efforts to agree to the
request. However, neither party is under a requirement to actually agree to such a request. The
requesting party will bear all costs of such cooperation. For purposes of clarification, given the
strategic relationship between the parties, each party expects to assert its patents for the
benefit of the other, unless the requested party, after commercially reasonable deliberations,
determines that such assertion is not in its reasonable best interests.

ARTICLE 3

NON ASSERTS

     Section 3.01 Non Asserts.

     A. Sampras Covenant. For the Covenant Term, Sampras, on behalf of itself and all Sampras Group
members, agrees not to bring, assert or commence against NewCo or any NewCo Group member any claim,
action or proceeding alleging that NewCo is making, using or selling, offering to sell, importing,
or otherwise infringing on the rights of any Sampras Patents or any Sampras VOIP Patents (the
“Sampras Covenant”). The Sampras Covenant will terminate immediately if Newco is acquired or
controlled by a Sprint Restricted Entity other than Sampras or a member of the Sampras Group.

     B. Assigned Patents Covenant. For the term of the Assigned Patents, NewCo, on behalf of itself
and all NewCo Group members, agrees not to bring, assert or commence against Sampras or any Sampras
Group member any claim action or proceeding alleging that Sampras is making, using or selling,
offering to sell, importing, or otherwise infringing on the rights of any of the Assigned Patents
including any continuations, divisionals or any patent which claims priority to any assigned
patents or patent applications. Unless this Agreement is terminated by NewCo as a result of a
material breach by Sampras, this Section shall survive the termination of this Agreement.

     C. Newco Covenant. For the Covenant Term, NewCo, on behalf of itself and all NewCo Group
members, agrees not to bring, assert or commence against Sampras or and Sampras Group member any
claim action or proceeding alleging that Sampras is making, using or selling, offering to sell,
importing, or otherwise infringing on the rights of any NewCo Patent
(the “Newco Covenant”). The
Newco Covenant will terminate immediately if Sampras is acquired or controlled by a Restricted
Entity.

     D. Sampras and NewCo agree that no damages for patent infringement, or claims to patent
royalties, in respect of the patents subject to this Agreement, shall accrue during the period
in which this Non-Assert Section is in effect.

     Section 3.02 Third Parties and Sampras VOIP Patents.

     (a) While a covenant of this Article 3 remains in effect:

4

 

     (i) With respect to patents that Sampras has agreed not to assert against
NewCo, the non assert will also extend to (a) selling by any Person that is
authorized to sell NewCo services but only as to the NewCo services being sold, and
not any services or products of any Third Party, and (b) use by any client or
customer that has the right to use NewCo services. For the avoidance of doubt
Sampras may pursue claims against a Third Party who uses NewCo’s services in the
conduct of such Third Party’s business in combination with a service not provided by
NewCo, which combined use infringes a Sampras patent, solely to the extent such
infringement would not have occurred but for such combination. For further avoidance
of doubt, Sampras will not have a claim against a NewCo customer that uses only the
NewCo service(s).

     (ii) With respect to patents that NewCo has agreed not to assert against
Sampras, the non assert will also extend to (a) selling by any Person that is
authorized to sell Sampras services but only as to the Sampras services being sold,
and not any services or products of any Third Party, and (b) use by any client or
customer that has the right to use Sampras services. For the avoidance of doubt NewCo
may pursue claims against a Third Party who uses Sampras’ services in combination
with a service not provided by Sampras, which combined use infringes a NewCo patent,
solely to the extent such infringement would not have occurred but for such
combination. For further avoidance of doubt, NewCo will not have a claim against a
Sampras customer that uses only the Sampras service(s).

     (iii) If, after the Effective Date, any party grants any Third Party the right
to enforce a patent, through assignment or otherwise, then that party will obligate
the Third Party to honor the provisions of this Article 3 and will take all
necessary steps to ensure that the Third Party has the same obligation not to assert
that patent.

     (b) Sampras may update Exhibit H from time to time during the Covenant Term. NewCo may
request no more often than annually that Sampras update Exhibit H. Within 30 days of receipt of
the request, Sampras will update Exhibit H.
