        (iii)  COMPLIANCE.  Each of Heartland and CS Wireless shall have

     filing with any Governmental Authority or any other Person (other than as
     has been duly made or obtained) pursuant to, the charter or bylaws of
     Heartland, or any law, statute, rule or 

                                     13

<PAGE>

     regulation to which Heartland or any of its assets is subject, or any 
     agreement, instrument, order, judgment or decree to which Heartland or 
     any of its assets is subject.
     
          (v)  COMPLIANCE WITH LAWS.  Except as set forth on SCHEDULE 8(a)(v),
     Heartland is in compliance in all material respects with all laws, rules
     and regulations applicable to the Portsmouth Non-FCC Assets, the Heartland
     FCC Assets and Heartland Leases (including obtaining all authorizations,
     consents, approvals, orders, licenses, exemptions from, and making all
     filings or registrations or qualifications with, any Governmental
     Authority), the noncompliance with which reasonably could have a material
     adverse effect on such assets or the use thereof, and Heartland is in
     compliance in all material respects with all provisions of applicable FCC
     licenses including, without limitation, any build-out requirements and
     other obligations, and with all leases, subleases and sublicenses to it of
     MMDS or MDS channels comprising the Heartland FCC Assets or the Heartland
     Leases, as the case may be.  The FCC licenses and channel leases comprising
     the Heartland FCC Assets and Heartland Leases conform in all material
     respects to all applicable laws, ordinances, codes, licensing requirements,
     rules and regulations, and Heartland has not received any notice to the
     contrary.  Except as set forth on SCHEDULE 8(a)(v), there are no
     proceedings or complaints or, to the best of Heartland's knowledge,
     investigations pending before or by any Governmental Authority which could
     reasonably be expected to have a material adverse effect on any FCC license
     or channel lease comprising the Heartland FCC Assets or Heartland Leases. 
     All applications, reports, fees, filings and other submissions required
     under the Communications Act relating to the Heartland FCC Assets and
     Heartland Leases have been made or paid in a timely fashion.
     
          (vi) FCC LICENSES.  Schedule 3(b) attached hereto correctly sets forth
     all of the FCC licenses comprising the Heartland FCC Assets and correctly
     sets forth the termination date of each such FCC license, and SCHEDULE
     4(b)(i) attached hereto identifies all FCC licenses and the owner thereof

     Leases.  Each FCC license comprising the Heartland FCC Assets or the
     Heartland Leases allowing the construction or the operation of radio
     station facilities by a lessor of channel capacity who is obligated to
     lease the capacity of the radio station (in whole or in part) under a lease
     agreement or management/option agreement listed on SCHEDULES 3(b) or
     4(b)(i) attached hereto is in full force and effect, and, to the best of
     Heartland's knowledge, neither the licensee of such FCC license nor the FCC
     license is subject to any complaint, investigation or proceeding by or
     before the FCC, or on appeal from the FCC, which looks toward or would
     result in the revocation, modification or non-renewal of the FCC license. 
     Except as set forth on SCHEDULE 8(a)(vi), each of such FCC licenses for an
     MMDS or MDS station has a construction completion date which has not
     elapsed or, if such date has elapsed, a request to the FCC to extend that
     date for at least six (6) months has been properly filed and is pending, or
     an application for certification or completion of construction has been
     properly filed.  Except as set forth on SCHEDULE 8(a)(vi),  the FCC has
     granted one or more FCC licenses to each lessor of the channel capacity

                                     14

<PAGE>

     subject to the lease and lease/option agreements comprising the Heartland
     FCC Assets or the Heartland Leases allowing that lessor to construct and/or

     under each such agreement executed by such lessor the channel capacity
     subject to that agreement.

         (vii)  LITIGATION.  Except as set forth on SCHEDULE 8(a)(vii),
     there is no action, suit, proceeding, arbitration, litigation or government
     proceeding (including, without limitation, those related to FCC,
     environmental or similar matters), or inquiry or investigation by any
     Governmental Authority known to Heartland, in each case domestic or
     foreign, pending against, or involving the Heartland FCC Assets, the
     Heartland Leases or the Portsmouth Non-FCC Assets or the use thereof which
     (A) questions the validity of this Agreement or any action taken or to be
     taken by Heartland pursuant to or in connection with this Agreement, (B) is
     required to be, and has not been, so disclosed in the filings with the SEC
     by Heartland (and such proceedings as are summarized in such SEC filings
     are accurately described in all material respects), or (C) could reasonably
     be expected to materially adversely affect the FCC licenses or channel
     leases comprising the Heartland FCC Assets and the Heartland Leases or the
     operation of the channels and transmission facilities relating thereto.
     
         (viii)  NO VIOLATION, ETC.  Heartland has not violated any law or
     any governmental regulation or requirement which violation has had or would
     reasonably be expected to have a material adverse effect upon the financial
     condition, operating results, assets, operations or business prospects of
     Heartland relating to the Heartland FCC Assets, the Heartland Leases or the
     Portsmouth Non-FCC Assets, and Heartland has not received notice of any
     such violation.  Heartland is not subject to, or has reason to believe it
     may become subject to, any material liability (contingent or otherwise) or
     corrective or remedial obligation arising under any environmental law, rule
     or regulation relating to the Heartland FCC Assets, the Heartland Leases or
     the Portsmouth Non-FCC Assets. 

         (ix)  COPYRIGHT MATTERS.  Heartland has submitted all requisite notices
     (if any are required) under the Copyright Act for the carriage of all
     Broadcast Stations as currently carried over any of the Heartland FCC
     Assets.  Heartland has filed in a timely manner with the Copyright Office
     all required documents, instruments and statements of account and have
     remitted payments of all required royalty fees with respect to compulsory
     licenses provided for in Section III of the Copyright Act for the carriage
     of broadcast signals in connection with the Heartland FCC Assets. 
     Heartland is not liable to any Person for copyright infringement under the
     Copyright Act as a result of its business operations relating to the
     Heartland FCC Assets and the Heartland Leases.  There have been no
     inquiries received from the Copyright Office or any other party, which
     questioned such statements of account or any copyright royalty payments
     made by Heartland with respect to the Heartland FCC Assets or Heartland
     Leases, and no claim, action or demand for copyright infringement or for
     non-payment of royalties is pending or, to the knowledge of Heartland,
     threatened against Heartland with respect to the Heartland FCC Assets or
     Heartland Leases.

          (x)  CONDITION OF PORTSMOUTH NON-FCC ASSETS.  Except as set forth on
     SCHEDULE 8(a)(x) and except for ordinary wear and tear, the Portsmouth 
     Non-FCC Assets are in good working order for the purpose for which they 
     were intended.  All transmitters included in the Portsmouth Non-FCC Assets 
     used in the Portsmouth market meet all material applicable FCC acceptance 
     and frequency stability requirements.
          
          (xi) NO INTERFERENCE CAUSED BY PORTSMOUTH MARKET.  With respect to its
     Portsmouth market, Heartland has not received any written complaint that

     to any reception, transmission or detection system.

     comprising the CS Wireless FCC Assets or CS Leases or the operation of the
     channels and transmission facilities relating thereto.
     
          (viii)  NO VIOLATION, ETC.  CS Wireless has not violated any law or
     any governmental regulation or requirement which violation has had or would

     condition, operating results, assets, operations or business prospects of
     CS Wireless relating to the CPE, the CS Wireless FCC Assets, the CS Leases
     or the Radcliffe Non-FCC Assets, and CS Wireless has not received notice of
     any such violation.  CS Wireless is not subject to, or has reason to
