                    proceedings involving the Circuit City Licensed Marks.

               4.3.7.2 Any recovery obtained in connection with or as a result
                    of any infringement action contemplated under this section,
                    whether by settlement or otherwise, shall be retained by

8.   PUBLICITY. Neither Party shall issue a press release or similar public
     announcement of any kind regarding the Parties' relationship established
     hereunder without the prior written approval of the other Party. Other than
     expressly set forth herein, neither Party shall use publicly the other
     Party's name or refer to the other Party in any way in or with the media,
     including, but not limited to, in advertising, without the other Party's
     prior written consent as required herein; provided, however, that either

     laws, including filings with regulatory agencies, such as the United States

          acts or omissions or those of persons furnished by Clearwire, (c) any
          employee or former employee of Clearwire or any of its sublicensees or
          subcontractors for which Clearwire's or its sublicensee's or
          subcontractor's liability to such employee or former employee would
          otherwise be subject to payments under the state Worker's Compensation
          or similar laws, (d) Clearwire's actual or alleged breach of any
          applicable law, statute, order, decree or regulation in performance of
          its obligations, or (e) any third party claim based upon any marketing
          material provided by Circuit City which Clearwire materially alters
          and uses without Circuit City's prior consent in accordance with
          Section 4.3 above. Circuit City agrees to promptly notify Clearwire of
          written claims or demands made against Circuit City, which Circuit
          City has received written notice of, for which Clearwire is
          responsible hereunder. Circuit City further agrees to assist Clearwire
          in its defense of such claim, at reasonable cost to Clearwire.
          Clearwire shall bear full responsibility for the defense (including
          any settlements) of any such claim; provided however, that (i)
          Clearwire shall not have any right, without Circuit City's written
          consent, to settle any such claim if such settlement arises from or is
          part of any criminal action, suit or proceeding or contains a
          stipulation to or admission or acknowledgment of, any liability or
          wrongdoing (whether in contract, tort or otherwise) on the part of
          Circuit City, or provides for less than a full release of Circuit
          City. Circuit City shall be entitled to participate in the action with
          counsel of its choice at its own expense. Clearwire shall not be
          responsible for any claims arising under (a) and/or (e) where Circuit
          City was informed of a claim or notice of infringement and failed to
          promptly remove or cease in the distribution of the infringing
          materials.

     11.2 In connection with Circuit City's performance under this Agreement,
          Circuit City agrees to indemnify, defend and hold harmless Clearwire,

          lawsuits, penalties, claims or demands (including all costs, expenses,
          and reasonable attorneys' fees on account thereof) arising out of or
          in connection with (a) any third party claims for actual or alleged
          infringement of a third party's intellectual property rights, (b) any
          employee or former employee of Circuit City or any of its sublicensees
          or subcontractors for which Circuit City's or its sublicensee's or
          subcontractor's liability to such employee or former employee would
          otherwise be subject to payments under the state Worker's Compensation
          or similar laws, (c) Circuit City's actual or alleged breach of any
          applicable law, statute, order, decree or regulation in performance of
          its obligations, or (d) any third party claim based upon any marketing
          material provided by Clearwire which Circuit City materially alters
          and uses without Clearwire's prior consent in accordance with Section
          4.2 above. Clearwire agrees to promptly notify Circuit City of written
          claims or demands made against Clearwire, which Clearwire has received
          written notice of, for which Circuit City is responsible hereunder.
          Clearwire further agrees to assist Circuit City in its defense of such
          claim, at reasonable cost to Circuit City. Circuit City shall bear
          full responsibility for the defense (including any settlements) of any
          such claim; provided however, that (i) Circuit City shall keep
          Clearwire informed of, and consult with Clearwire in connection with
          the progress of such litigation or settlement; and (ii) Circuit City
          shall not have any right, without Clearwire's written consent, to
          settle any such claim if such settlement arises from or is part of any
          criminal action, suit or proceeding or contains a stipulation to or
          admission or acknowledgment of, any liability or wrongdoing (whether
          in contract, tort or otherwise) on the part of Clearwire or any
          Clearwire Affiliate, or provides for less than a full release of
          Clearwire. Clearwire shall be entitled to participate in the action
          with counsel of its choice at its own expense. Circuit City shall not
          be responsible for any claims arising under (d) where Clearwire was
          informed of a claim or notice of infringement and failed to promptly
          remove or cease in the distribution of the infringing materials

12.  INSURANCE.

          or right of subrogation against Circuit City or Circuit City's
          customers based on any loss or liability insurable under the foregoing
          insurance, except to the extent Circuit City has an indemnification
          obligation under Section 11.2 for

  Not to be disclosed without written permission of Clearwire and Circuit City

          Insurance. Clearwire shall maintain insurance, as required by this
          Agreement, through insurance carriers which have and maintain an A.M.
          Best rating of A-VII or greater. The fulfillment of the insurance
          obligations hereunder shall not otherwise relieve Clearwire of any
          liability assumed by Clearwire hereunder or in any way modify
          Clearwire's obligations to indemnify Circuit City.

     12.4 Clearwire shall furnish, within ten (10) days of the Effective Date of
          this Agreement, certificates or adequate proof of the foregoing

13.  CONFIDENTIAL INFORMATION

     13.1 "Confidential Information" means any and all business, technical,
          customer or third party information (including but not limited to,
          trade secrets, marketing plans, financial data, specifications,
          drawings, sketches, models, samples, computer programs and
          documentation) provided, disclosed or made accessible by one Party
          (the "Disclosing Party") to the other (the "Receiving Party") under
          this Agreement, that is either identified as or would be reasonably
          understood to be confidential and/or proprietary. Confidential
          Information also includes (a) any Information that a Party receives,
          collects, learns of, or develops in the course of performing its
          obligations under this Agreement, including but not limited to
          prospective and actual customer's names, addresses, telephone numbers,
          email addresses, financial data, including credit card or banking
          information, and other customer information; and (b) the terms and
          conditions of this Agreement. Confidential Information does not
          include information that the Receiving Party can clearly establish by
          written evidence: (a) is or becomes known to the Receiving Party from
          a third party without an obligation to maintain its confidentiality;
          (b) is or becomes generally known to the public through no act or
          omission of the Receiving Party; or (c) is independently developed by
          the Receiving Party without the use of Confidential Information of the
          Disclosing Party. Clearwire will be the owner of any Subscriber
          Information generated by Clearwire in connection with a Subscriber's
          order for Services and such information will be deemed Clearwire
          Confidential Information for purposes of this Agreement. Circuit City
          will be the owner of any Confidential Information generated by Circuit
          City in connection with a Subscriber's order for Circuit City goods or
          services or otherwise in connection with Circuit City's performance of
          its duties and obligations hereunder and such information will be
          deemed Circuit City's Confidential Information. Any information
          obtained by both Parties shall be owned by each Party.

     13.2 Confidential Information will be deemed the exclusive property of the
          Disclosing Party. The Receiving Party will not: (a) use Confidential
          Information of the Disclosing Party for any purpose

                Clearwire/Circuit City Confidential Information

  Not to be disclosed without written permission of Clearwire and Circuit City


                                                                          Page 9

<PAGE>

          other than the fulfillment of its obligations under this Agreement;
          (b) disclose Confidential Information of the Disclosing Party to any
          third party, without the prior written consent of the Disclosing
          Party; (c) make any copies or modifications of Confidential
          Information of the Disclosing Party without the Disclosing Party's
          prior written consent, and provided that any authorized copies or
          modifications will contain the same confidential or proprietary
          notices or legends, if any, which appear on the original; and (d)
          reveal, divulge, make known, sell, exchange, lease or in any other way
          transfer any Confidential Information to any third party.

     13.3 The Receiving Party will: (a) protect and treat all Confidential
          Information of the Disclosing Party with the same degree of care as it
          uses to protect its own Confidential Information of like importance,
          but in no event with less than reasonable care; and (b) only disclose
          Confidential Information of the Disclosing Party to its employees
          and/or agents who have a "need to know" for purposes of this
          Agreement, provided that the Receiving Party will notify and inform
          such employees and/or agents of the Receiving Party's obligations
          under this Agreement, and the Receiving Party will be responsible for
          any breach of this Agreement by its employees and/or agents.

     13.4 In the event that the Receiving Party is required to disclose
          Confidential Information of the Disclosing Party pursuant to law, the
          Receiving Party will notify the Disclosing Party of the required
          disclosure with sufficient time for the Disclosing Party to seek
          relief, will cooperate with the Disclosing Party in taking appropriate
          protective measures, and will make such disclosure in a fashion that
          maximizes protection of the Confidential Information from further
          disclosure.

     13.5 Upon expiration or termination of this Agreement, the Receiving Party
          will promptly turn over to the Disclosing Party or, at the Disclosing
          Party's direction, destroy all Confidential Information of the
          Disclosing Party, in whole or in part, in whatever format, including
          any copies.

     13.6 Each Party agrees that monetary damages for breach of its obligations
          under this Section may not be adequate and that the non-breaching
          Party will be entitled to injunctive relief with respect thereto.

14.  ASSIGNMENT. Neither party may assign or otherwise transfer any of its
     rights or obligations hereunder without the prior written consent of the
     other, which shall not be unreasonably withheld; provided, however, that
     nothing herein shall prevent either party from assigning its rights and
     obligation under this Agreement to an Affiliate, or to an entity that
     acquires all or substantially all of the assets of such party through a
     merger, consolidation, or sale, provided further that the assigning party
     provides notice of such permitted assignment as soon as commercially
     reasonable.

15.  RELATIONSHIP BETWEEN THE PARTIES. The Parties to this Agreement are
     independent Parties and nothing herein shall be construed as creating an
     employment relationship between the Parties. Neither Party is an agent,
     representative, joint venturer nor partner of the other Party and neither
     Party shall have any right, power or authority to enter into any agreement
     for or on behalf of, or incur any obligation or liability, or to otherwise
     bind, the other Party. The Agreement shall not be interpreted or construed
     to create an association, agency, joint venture or partnership between the
     Parties or to impose any liability attributable to such a relationship upon
     either Party.

16.  FORCE MAJEURE. Neither Party shall be in default or otherwise liable for
     any delay in or failure of its performance under this Agreement if such
     delay or failure arises by any reason beyond its reasonable control,
     including any act of God, any acts of the common enemy, the elements,
     earthquakes, floods, fires, epidemics, riots, failures or delay in
     transportation, electricity or communications, or any act or failure to act
     by the other Party or such other Party's employees, agents or contractors;
     provided, however, that lack of funds shall not be deemed to be a reason
     beyond a Party's reasonable control. The Parties will promptly inform and
     consult with each other as to any of the above causes which in their
     judgment may or could be the cause of a delay in the performance of this
     Agreement.

                                                                         Page 10

17.  THIRD PARTY BENEFICIARIES. The provisions of this Agreement are for the
     sole benefit of the parties hereto and this Agreement confers no rights,
     benefits or claims upon any person or entity not a party hereto. Third
     party beneficiaries do not include Clearwire Affiliates.

18.  CHOICE OF LAW. The Parties agree that the substantive laws of the State of
     New York, without reference to its principles of conflicts of laws, will be
     applied to govern, construe and enforce all of the rights and duties of the
     Parties arising from or relating in any way to the subject matter of this
     Agreement. THE PARTIES KNOWINGLY AND VOLUNTARILY WAIVE ANY RIGHT TO TRIAL
     BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING ANY MATTER ARISING OUT OF, OR
     RELATED TO, THIS AGREEMENT.

19.  AUDIT RIGHTS. During the term of this Agreement and for a period of two (2)
     years following the expiration or termination of this Agreement, both
     Parties shall create and maintain sufficient books, records and accounts
     related to this Agreement according to generally accepted accounting
     practices. Each Party shall have the right, at its own expense, to inspect
     or direct an independent certified public accountant to inspect and audit
     those books and records of the other Party that are relevant to the
     determination of compensation payable hereunder, provided, however, that
     such audits will be conducted no more than once in any calendar year, upon
     not less than thirty (30) days' notice, during regular business hours, at
     mutually agreeable dates and times (not to be unreasonably withheld or
     delayed), and provided further that such accountant, if any, executes a
     confidentiality agreement reasonably satisfactory to the Party being
     audited, to protect the confidentiality of any records so audited. If the
     audit discloses a payment discrepancy or error, the Party responsible for
     correcting such error shall make any undisputed payment or remittance
     within thirty (30) business days of the generation of the audit report. In

     five (5) percent of the correct amount, the Party owing such payment or
     remittance shall bear the cost of the audit.

                                         EXHIBIT F
                                    EQUIPMENT AGREEMENT

THIS EQUIPMENT AGREEMENT ("Agreement") is made a part of and is hereby
incorporated into the Co-Marketing Agreement (the "Co-Marketing Agreement")
between Circuit City Stores, Inc. and its affiliates, having its principal place
of business at 9950 Mayland Drive, Richmond, Virginia, USA, 23221("Circuit
City") and Clearwire LLC having its principal place of business at 5808 Lake
Washington Blvd. NE, Suite 300, Kirkland, WA 98033 ("Clearwire"), which became
effective on Sept. 6, 2006. This Agreement is intended to set forth the terms
and conditions under which Clearwire will provide certain equipment (set forth
on Attachment 1, as may be amended from time to time) (the "Equipment") to
Circuit City; Circuit City will then provide the Equipment to Subscribers, which
the Subscribers lease directly from Clearwire. Terms used in this Agreement, but
not defined in this Agreement, have the meaning given in the Co-Marketing
Agreement

With respect to Equipment, the following terms shall supplement the terms of the
Co-Marketing Agreement

1. RESERVATION OF RIGHTS AND TITLE. Title to the Equipment is at all times
reserved to Clearwire. Circuit City agrees to cooperate with Clearwire in
effecting the protections afforded under Sections 9-103(d), 9-109 (a)(4) and 9-
319 of the Uniform Commercial Code as adopted and in effect (or parallel
protections, if the Uniform Commercial Code is not in effect) in each state in
which such a filing is necessary to effect such protections, to the extent
applicable under this Agreement; provided, however, Circuit City makes no
representation or warranty that Clearwire's interests in the Equipment will be
"perfected" as that term is defined in Article 9 of the Uniform Commercial Code,
however Circuit City shall not encumber such equipment nor interfere with such
perfected interest. Circuit City agrees to execute UCC-1 financing statements or
such other form as may be appropriate for the relevant state, provided that
Clearwire shall be responsible for preparation of such financing statements and
for the filing of such financing statements and payment of all applicable filing
and preparation costs. The parties acknowledge that the transaction described in
this Agreement is not a "consignment" within the meaning of the Uniform
Commercial Code. Circuit City shall take delivery of the Equipment from
Clearwire from time to time in accordance with this Agreement. Circuit City may
only distribute Equipment to Subscribers in a Clearwire service area (which
shall be subject to a sale or lease arrangement directly between Clearwire and
the Subscriber). The price for the Equipment shall be determined by Clearwire
and shall be stated in the equipment lease agreement between Clearwire and the
Subscriber (the "Equipment Lease Agreement"). Circuit City may not sell the
Equipment

2. LEASE OF EQUIPMENT. In accordance with the terms of the Co-Marketing
Agreement, Circuit City will register Subscribers for the Services. As part of
the registration process, each Subscriber will enter into an Equipment Lease
Agreement between the Subscriber and Clearwire. The lease price of the Equipment
shall be determined by Clearwire, in its sole discretion. Upon completion of the
registration process, Circuit City will give the leased equipment to the
Subscriber. In order to track Equipment in Circuit City's possession, Circuit
City will assign a stock-keeping unit to the Equipment. The Equipment will show
a price tag of [***] but will net to [***] upon a Subscriber's registration for
the Services; the [***] "price" will not be charged to Subscribers and is caused
by a point of sale systems limitation that prohibits the processing of free
tickets.

3. INVOICES; PAYMENT; ALLOWANCES. All transactions (e.g., purchase orders and
invoices) shall be conducted via Electronic Data Interchange (EDI). At
appropriate intervals, as determined by Circuit City, Circuit City will issue a
purchase order to Clearwire requesting additional Equipment. Upon receipt of a
purchase order, Clearwire will ship the requested Equipment pursuant to the
Circuit City Vendor Supply Chain Agreement dated June 9, 2006 and submit a
corresponding invoice to Circuit City that contains quantity and stock-keeping
unit information. Notwithstanding the terms on any purchase order or any
invoice, Circuit City and Clearwire agree that the Equipment will be provided at
no cost to Circuit City, and at all times thereafter, Clearwire shall continue
to retain title to the Equipment. Notwithstanding any term in any agreement
entered into between Circuit City and Clearwire in the event of a recall of
Equipment Clearwire will use commercially reasonable efforts to satisfy any
purchase

                                                                         Page 18

order issued by Circuit City, however Circuit City acknowledges and agrees that
complete fulfillment may not be possible and that in such instance Clearwire
shall not be in breach of any agreement for failure to completely satisfy any
purchase due to such circumstances. Circuit City shall ensure that its
merchandise receipt system automatically matches each invoice to the
corresponding Equipment delivery and purchase order issued by Circuit City. Any
discrepancies (e.g., shortages) identified by Circuit City will be reconciled
with Clearwire each month to assure that the parties agree to the correct
inventory of Equipment held by Circuit City. The parties will at this time make
any necessary corrections to their records concerning invoices and quantities.

4. INVENTORY AUDITS. Clearwire may audit Circuit City's distribution centers
pertaining solely to the subject matter of this Agreement no more than 1 times
per calendar quarter, provided that Circuit City shall be given seven (7) days
written notice, and further provided that the audit shall take place at Circuit
City's facilities during normal business hours. Costs of the audit shall be
borne by Clearwire, provided that if a five percent (5%) or greater discrepancy
is found in either amounts owed or Equipment inventory, Circuit City will
reimburse the reasonable and documented costs of such audit in addition to any
moneys owed.

5. TAXES. Because the Equipment is not being sold by Circuit City to the
Subscribers, Circuit City will NOT be responsible for the collection and
remittance of sales, use, or lease taxes to the proper taxing authorities;
Clearwire shall be solely responsible for any such collection and remittance of
sales, use or lease taxes to the proper taxing authorities. Clearwire will be
responsible for paying any personal property taxes relating to the Equipment in
Circuit City's possession; provided that the parties will cooperate to minimize
the amount of such personal property taxes. Furthermore, Clearwire agrees to
indemnify, defend and hold harmless Circuit City and its affiliates, and each of
their officers and directors against any penalty, additional tax or interest
that may be assessed or levied as a result of the failure to timely collect or
pay any tax, or to file any return, form or information statement that may be
required by any governmental agency. Provided, however, that Clearwire shall not
be obligated to indemnify Circuit City in the event that (i) Clearwire was not
timely notified of the claim or potential claim, and/or (ii) such claim arises
out Circuit City's process or procedures relating to the sale or accounting of
Equipment as set forth in Section 2. Circuit City shall not report the Equipment
as property of Circuit City. Each party shall be responsible for reporting its
own income derived from this Agreement and for payment of its own income taxes.

6. SHIPMENTS. Clearwire will ship the Equipment to Circuit City's designated
shipping address (e.g., distribution centers and/or stores) at Clearwire's risk
and expense. Clearwire shall be responsible for making shipping arrangements,
scheduling, tracking, proof of delivery, tracing, and obtaining insurance for
loss or damage while Equipment is in transit, and filing freight claims for loss
and/or damage. If expedited shipment becomes necessary, in the reasonable
opinion of both parties, due to the fault or delay of Clearwire, then Clearwire
shall pay the costs of such expedited shipments to either Circuit City's
distribution centers or via drop ships to Circuit City's stores, as requested by
Circuit City. If expedited shipment becomes necessary, in the reasonable opinion
of both parties, due to the fault or delay of Circuit City, then Clearwire
agrees to ship product, freight collect, to either Circuit City's distribution
centers, or stores via drop ship, as requested by Circuit City; Circuit City
shall then chargeback Clearwire the difference between the standard ground
shipping costs and the expedited shipping costs. The carrier (not Clearwire)
shall invoice Circuit City in this latter freight collect situation. Clearwire
agrees not to include freight charges on any invoices under any circumstances.

7. RETURN OF GOODS. [***] Except as otherwise expressly set forth in this
Agreement, Circuit City agrees to arrange and pay for return shipments.
Notwithstanding the foregoing, Circuit City reserves the right to return, at
Clearwire's expense, any Equipment for which a claim is made that alleges that
the Equipment (1) infringes any alleged patent, design, trade name, trademark,
copyright, right of privacy, or any other tangible or intangible property
rights, or (2) is not manufactured, packaged and labeled in accordance with
industry standards and/or all applicable laws, ordinances, rules and regulations
by governmental departments, bodies and agencies governing and/or restricting
the receipt and sale of Equipment by the undersigned Circuit City, or (3) has
caused injury to person or property. In addition, Clearwire agrees to pay the
cost of return shipments of substantially defective product. Equipment that is
defective (which includes but is not limited to Equipment that is returned
without the box, with an opened box, or with a damaged box) shall be the
responsibility of Clearwire, and may be returned to

Clearwire unless otherwise mutually agreed. In all cases, Clearwire agrees to
provide a return authorization ("RA") within 48 hours of request submitted to
Clearwire in accordance with Clearwire's procedures.

8. FURTHER OBLIGATIONS OF CIRCUIT CITY.

     a. Circuit City will pay Clearwire [***](the "Agreed Cost') for each unit
of Equipment of the type listed on Attachment 1 that is lost, stolen or damaged
while in Circuit City's possession, less any applicable discounts, allowances or
other valid off set amounts. Notwithstanding the foregoing, Circuit City agrees
to use commercially reasonable efforts to protect and preserve the Equipment
that is in its care, custody or control, wherever located. Circuit City further
agrees to maintain all-risk property insurance in an amount adequate to fully
insure all Equipment in its care, custody or control, wherever located, in an
amount not less than $5 Million, and will name Clearwire.

     b. Circuit City agrees to deliver to Subscribers, in accordance with
Clearwire's instructions and activation procedures, Equipment to be used by
Subscribers for their use of the Services. Circuit City may only offer Equipment
that is approved by Clearwire. Circuit City agrees to cooperate with Clearwire
in order to maintain a mutually agreed upon inventory of Equipment that is
sufficient, in, to meet reasonably anticipated demand by Subscribers that
Circuit City enrolls for the Services. From the time of delivery of the
Equipment to Circuit City's location until delivery to a Subscriber in
accordance with this Agreement, Circuit City will store all Equipment delivered
to Circuit City in a safe and secure location, all at Circuit City's expense.
Prior to delivery to a Subscriber in accordance with mutually agreed
authorization procedures, the Equipment may upon mutual agreement be upgraded or
otherwise modified by Clearwire. Upon Clearwire's reasonable demand, Circuit
City will ship all or any portion of the Equipment to Clearwire, at Clearwire's
expense; provided, however, Clearwire shall not pull any Equipment from Circuit
City for the purpose of supplying Equipment to another Clearwire reseller or
representative. Clearwire will have the right, from time to time, to sell,
lease, or otherwise dispose of, all or any potion of the Equipment to a third
party, at prices and on terms established by Clearwire in its sole discretion,
and Clearwire will have no obligation to share any proceeds from such sale with
Circuit City.

9. TERM; TERMINATION. The term of this Agreement shall commence on the Effective
Date, and shall continue until expiration or termination of the Co-Marketing
Agreement, and shall automatically renew on the same terms applicable to the
Co-Marketing Agreement. Termination shall not affect the parties' respective
outstanding obligations.
