PATENT TRANSFER

Section 2.01 Patent Transfer to Clearwire. Sprint hereby assigns and will cause each Sprint Group member to assign to the Clearwire Group member designated by Clearwire, subject to any rights of Third Parties existing on the Effective Date, all the Sprint Group’s right, title and interest in the Assigned Patents. To the best of Sprint’s 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, Sprint will give Clearwire reasonable notice of such right. Following execution of the assignment, Clearwire shall assume all responsibility and expenses associated with processing and pursuing the Assigned Patents.

Section 2.02 Exhibit A. To the best of Sprint’s knowledge, Exhibit A is a complete list of all Assigned Patents. Sprint 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 Clearwire for inclusion of a Sprint Patent which Clearwire has reason to assert is an Assigned Patent.

Section 2.03 Cooperation.

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

Party, and (iii) executing any applicable documents requested by Clearwire to perfect ownership and register patent assignments with any patent office.

(b) Clearwire will reasonably cooperate with Sprint, and will cause all Clearwire Group members, agents and counsel to reasonably cooperate with Sprint, at Sprint’s expense with respect to Third Party costs, in connection with (i) the preparation, filing, prosecution, maintenance and defense of the Sprint Patents, and (ii) any suit for infringement of the Sprint Patents brought by a Sprint Group member against a Third Party, and (iii) executing any applicable documents requested by Sprint 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. Sprint Covenant. For the Covenant Term, Sprint, on behalf of itself and all Sprint Group members, agrees not to bring, assert or commence against Clearwire or any Clearwire Group member any claim, action or proceeding alleging that Clearwire is making, using or selling, offering to sell, importing, or otherwise infringing on the rights of any Sprint Patents or any Sprint VOIP Patents (the “Sprint Covenant”). The Sprint Covenant will terminate immediately if Clearwire is acquired or controlled by a Sprint Restricted Entity other than Sprint or a member of the Sprint Group.

B. Assigned Patents Covenant. For the term of the Assigned Patents, Clearwire, on behalf of itself and all Clearwire Group members, agrees not to bring, assert or commence against Sprint or any Sprint Group member any claim action or proceeding alleging that Sprint 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 Clearwire as a result of a material breach by Sprint, this Section shall survive the termination of this Agreement.

C. Clearwire Covenant. For the Covenant Term, Clearwire, on behalf of itself and all Clearwire Group members, agrees not to bring, assert or commence against Sprint or and Sprint Group member any claim action or proceeding alleging that Sprint is making, using or selling, offering to sell, importing, or otherwise infringing on the rights of any Clearwire Patent (the

“Clearwire Covenant”). The Clearwire Covenant will terminate immediately if Sprint is acquired or controlled by a Restricted Entity.

D. Sprint and Clearwire 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 Sprint VOIP Patents.

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

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

(ii) With respect to patents that Clearwire has agreed not to assert against Sprint, the non assert will also extend to (a) selling by any Person that is authorized to sell Sprint services but only as to the Sprint 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 Sprint services. For the avoidance of doubt Clearwire may pursue claims against a Third Party who uses Sprint’s services in combination with a service not provided by Sprint, which combined use infringes a Clearwire patent, solely to the extent such infringement would not have occurred but for such combination. For further avoidance of doubt, Clearwire will not have a claim against a Sprint customer that uses only the Sprint 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) Sprint may update Exhibit H from time to time during the Covenant Term. Clearwire may request no more often than annually that Sprint update Exhibit H. Within 30 days of receipt of the request, Sprint will update Exhibit H.

ARTICLE 4
TRADEMARK TERMS AND CONDITIONS

Section 4.01 Trademarks Assignment.

(a) Sprint hereby assigns and will cause each applicable Sprint Group member to assign to the Clearwire Group member designated by Clearwire, all of their right, title and interest in the trademarks identified on Exhibit B (“Trademarks”) and all associated goodwill and related trademark registrations and applications worldwide, free and clear of all liens and encumbrances, and including the sole right to xxx for past infringements of the Exhibit B marks and logos. To the best of Sprint’s knowledge, Exhibit B is a complete list of all XOHM-formative trademarks owned by any member of the Sprint Group other than any composite trademarks that incorporate “Sprint”. Sprint shall, from time to time, revise Exhibit B to include all XOHM-formative trademarks that were not included on Exhibit B as of the Effective Date (other than any composite trademarks that incorporate “Sprint”), and shall act reasonably in considering any written request by Clearwire for inclusion of a XOHM-formative trademark which Clearwire has reason to assert is an XOHM-formative trademark that does not incorporate “Sprint” and that should be included in the Trademarks.

(b) Within the later of 5 business days of this Agreement, or after Clearwire designates the Clearwire Group member to receive the assignment, Sprint will cause the applicable Sprint Group member to sign and deliver the Memorandum of Assignment attached as Exhibit C.

Sprint will cause the applicable Sprint Group member to take additional steps and to sign additional documents as reasonably requested by Clearwire to perfect this trademark assignment worldwide.

Sprint will cause the applicable Sprint Group member to perform all steps reasonably required by the applicable registrar(s) to promptly complete the transfer of the Domain Names at Clearwire’s ultimate expense.

Section 9.04 Assignment. This agreement cannot be assigned by either party without the other party’s prior written consent except that any party can assign this agreement (i) to any member of its Group (but only for so long as the assignee remains a Group member) or (ii) in the event of a merger or acquisition so long as the acquiring party is not a Sprint Restricted Entity..
