hereby  acknowledged,  and Parent and Purchaser  hereby  consent,  that Sellers'
receipt, acceptance and performance of service orders placed under a Section 5.1

such  Section  5.1  Agreement  shall not  constitute  a


material amendment or modification of such Section 5.1 Agreement for purposes of
Section 5.1(b)(i).

     Section.  5. Deletion of Section  5.1(b)(ii)(D).  Section  5.1(b)(ii)(D) is
hereby deleted in its entirety.

     Section. 6. Amendment of Section 5.1(b)(iii). Section 5.1(b)(iii) is hereby
amended and restated in its entirety as follows:

     of any Other  Non-Transferred  FCC  Licenses (a "License  Termination")  in
     which the only breach of the Agreement  that would arise out of the License

     consequences.

     Section.  8. Partial  Waiver of Section  5.1(d)(iii)  for Service Orders of
Less Than  $100,000.  The  compliance by Sellers with Section  5.1(d)(iii)  with

deleted.

Section  5.1(d)(iv)(A) is hereby waived,  subject to Sellers providing Purchaser

deemed to have become effective as of the date of the Purchase Agreement.

     Section. 20. Limitation on Consent.  This Amendment,  Consent and Waiver is

amendment to, consent with respect to, or waiver of, any other  provision of the
Purchase  Agreement,  which shall remain in full force and effect. To the extent
an action  would  have in the  absence  of this  Amendment,  Consent  and Waiver
constituted a breach of both a provision  amended,  waived or deleted hereby and
another provision of the Purchase Agreement,  following this Amendment,  Consent
and Waiver such action would still constitute a breach of such other provision.


     Section. 21.  Miscellaneous.  All terms and provisions contained in Article
XIII of the Purchase Agreement (other than  Sections 13.4,  13.5, 13.6 and 13.13

reference to the same extent as if expressly set forth herein.
