                                    RECITALS


     WHEREAS, Company and Lenders desire to waive compliance with the provisions
of subsection 4.3H of the Credit Agreement and to amend the Credit Agreement to
make certain amendments as set forth below;

     NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, the parties hereto agree as follows:


SECTION 1. AMENDMENTS TO THE CREDIT AGREEMENT

     A. AMENDMENTS TO SECTION 1: DEFINITIONS

     (i) Subsection 1.1 is hereby amended by restating the definition of
"Adjusted Consolidated Operating Cash Flow" in its entirety as follows:

     ""ADJUSTED CONSOLIDATED OPERATING CASH FLOW" means Consolidated Operating
     Cash Flow; provided that (A) for any relevant period through September 30,
     1998, to the extent that the operating cash flow on a trailing 12 month
     basis relating to the Flagstaff and Kingman Stations (on a combined basis
     in accordance with GAAP) included in the calculation of Consolidated
     Operating Cash Flow for any such period is negative, such negative combined
     operating cash flow for such period shall be deemed to be zero for purposes
     of calculating Adjusted Consolidated Operating Cash Flow hereunder
     (provided, however, that no more than $300,000 in the aggregate of negative
     combined operating cash flow for all such Stations may be excluded in any
     such period) and (B) for any relevant period during the first consecutive
     twelve months following the pre-Closing Date programming format change for
     Station KIXA(FM), licensed to Lucerne Valley, California, implemented on
     March 15, 1998, and Station KNRO(AM), licensed to Redding, California,
     implemented on December 1, 1997, to the extent the operating cash flow on a
     trailing 12- month basis for any such Station (on a stand-alone basis)
     included in Consolidated Operating Cash Flow for any such period is
     negative, such negative combined operating cash flow for such period shall
     be deemed to be zero for purposes of calculating Adjusted 



                                     Page 1
   2


     Consolidated Operating Cash Flow hereunder (provided, however that the
     aggregate amount of negative operating cash flow that may be so excluded
     pursuant to the immediately preceding proviso shall not exceed $140,000 for
     KIXA(FM) and $92,000 for KNRO(AM))."

     (ii) Subsection 1.1 is hereby further amended by adding the following
proviso to the end of the definition of "Consolidated Operating Cash Flow":

     "; provided that for any period in which any Credit Party has acquired, or
     disposed of, a Station, Consolidated Operating Cash Flow shall be
     calculated on a pro forma basis as if such acquisition or disposition had
     occurred on the first date of such period and shall be adjusted to give
     effect to any cost savings arising from the consolidation or automation of
     operations or elimination of redundancies resulting from such transaction,
     all of the foregoing pro forma calculations and adjustments to be
     satisfactory to Agent in the case of aggregate adjustments not exceeding
     $100,000 and satisfactory to Requisite Lenders in the case of aggregate
     adjustments in excess of such amount; provided further that the foregoing
     adjustments resulting from Permitted Acquisitions occurring on the Closing
     Date shall not exceed $1,475,000."

SECTION 2. WAIVER

     Lenders hereby waive compliance with the provisions of subsection 4.3H of
the Credit Agreement requiring that the Acquisition FCC Consent with respect to
radio stations KNNN(FM), KRDG(FM), KRRX(FM) and KNRO(AM) (collectively, the
"ALTA STATIONS") shall have become a Final Order on or before the Permitted
Acquisition Closing Date with respect to the Alta Stations; provided that if the
FCC takes action to prevent such Acquisition FCC Consent from becoming a Final
Order, or if such Acquisition FCC Consent shall not be a Final Order, for any
reason, as of July 10, 1998, then, in either event, an Event of Default shall be
deemed to have occurred.


SECTION 3. LIMITATION OF AMENDMENT AND WAIVER

     Without limiting the generality of the provisions of subsection 10.6 of the
Credit Agreement, the amendment and waiver set forth above shall be limited
precisely as written and relate solely to the matters expressly set forth in
Sections 1 and 2 hereof, in the manner and to the extent described above, and
nothing in this Amendment shall be deemed to:

          (a) constitute a waiver of compliance by Company with respect to any
     other term, provision or condition of the Credit Agreement or any other
     instrument or agreement referred to therein; or

          (b) prejudice any right or remedy that Agent or any Lender may now
     have (except to the extent such right or remedy was based upon
     noncompliance or defaults that will not exist after giving effect to this
     Amendment) or may have in the future under or in connection with the Credit
     Agreement or any other instrument or agreement referred to therein.

     Except as expressly set forth herein, the terms, provisions and conditions
of the Credit Agreement and the other Loan Documents shall remain in full force
and effect and in all other respects are hereby ratified and confirmed.


SECTION 4. COMPANY'S REPRESENTATIONS AND WARRANTIES

     In order to induce Lenders to enter into this Amendment, Company hereby
represents and warrants that after giving effect to this Amendment:

          (a) there exists no Event of Default or Potential Event of Default
     under the Credit Agreement;

          (b) all representations and warranties contained in the Credit
     Agreement and the other Loan Documents are true, correct and complete in
     all material respects on and as of the date hereof except to the extent
     such representations and warranties specifically relate to an earlier date,
     in which case they were true, correct and complete in all material respects
     on and as of such earlier date; and

          (c) Company has performed all agreements to be performed on its part
     as set forth in the Credit Agreement.

     effect and are hereby ratified and confirmed.
