                       9/30/98             -0-
                       10/31/98            $8,000,000
                       12/31/98            $3,000,000

               (c)  Anything to the contrary contained in Section 2.2(a) above
          notwithstanding, it is hereby agreed among the parties hereto that
          Foothill shall establish a supplementary interest payment reserve
          against the Term Loan in the aggregate amount of $300,000, such
          reserve to be applied to reduce the amount of proceeds of Supplemental
          Term Loan No. 4 otherwise available on the Amendment Date by $300,000
          to provide for the payment of a portion of the estimated interest
          payments to be due Foothill on Borrower's Obligations as of the end of
          each month from the Amendment Date through the earlier of October 31,
          1998 or the date on which such supplementary interest payment reserve
          is exhausted, such interest payment reserve to be effective and
          commence as of the Amendment Date. On the first day of each month
          following the Amendment Date until all amounts contained in the
          supplementary interest payment reserve are exhausted, additional
          proceeds an amount equal to the amount of interest due on Obligations
          shall be advanced under Supplemental Term Loan No. 4, reducing the
          amount of the supplementary interest payment reserve by a
          corresponding amount, and shall be applied to the Loan Account as
          payment of interest due on the Obligations in excess of the aggregate
          amount of Collections received and applied by Foothill with respect to
          interest due on the Obligations in the corresponding period.

                                       3

          5.   Section 7.17 of the Loan Agreement is hereby amended to delete 
the proviso at the end of such Section, and to replace such proviso with the
following:

               ; provided, however, that in no event shall any advance under the
          Supplemental Term Loan No. 4 be used to finance, in whole or in part,
          directly or indirectly, (1) any Permitted Unrestricted Subsidiary
          Acquisition, or (2) to advance, by way of loan, investment or
          guaranty, or otherwise, any monies or credit to or for the benefit,
          directly or indirectly, of Harmony.

          6.   Conditions Precedent to Effectiveness of Amendment. The
effectiveness of this Amendment and the obligation of Foothill to make the
Supplemental Term Loan No. 3 is subject to the completion, to the satisfaction
of Foothill and its counsel, of each of the following conditions on or before
the Amendment Date:

               (a)  Foothill shall have received executed consents and
reaffirmations from each Guarantor, in form and substance satisfactory to
Foothill;

               (b)  Foothill shall have received an amendment fee of $100,000
which shall be earned in full and non-refundable as of the date hereof. The
payment of such amendment fee shall be paid on the Amendment Date out of the
proceeds of the Supplemental Term Loan No. 4. 

          7.   Forbearance. Foothill and Borrower hereby acknowledge that 
certain Events of Default previously disclosed to Foothill by Borrower
(including without limitation those certain Events of Default acknowledged and
disclosed Foothill by Borrower in those certain letters from Borrower to
Foothill, dated as of March 3, 1998 and May 8, 1998) have occurred and are
continuing under the Loan Agreement (the "Current Defaults"). Foothill hereby
agrees to forebear from taking any action or exercising any of its remedies
under the Loan Agreement with respect to the Current Defaults during the period
from October 1, 1998, through and including October 31, 1998; provided, however,
that such forbearance shall apply only to the Current Defaults, shall not apply
to any other Event of Default continuing as of the Amendment Date, or to any
Event of Default that may occur after the Amendment Date. Further, this
forbearance shall not constitute a waiver by Foothill of any of its rights or
remedies under the Loan Agreement, but shall only constitute a limited
forbearance. Furthermore, nothing contained in this letter shall diminish,
prejudice or waive any of Foothill's rights or remedies under the Loan Agreement
or applicable law, and Foothill hereby reserves all such rights and remedies.

          Anything contained in the foregoing to the contrary notwithstanding,
Foothill's continued forbearance with respect to the Current Defaults shall be
contingent on Borrower's successful consummation of the sale of certain of
Borrower's radio stations to Catholic Radio Network, LLC ("CRN") pursuant to the
transactions contemplated in the proxy statement with respect to the sale of
such radio stations to CRN (the "Proxy"), in accordance with the approvals
obtained from the holders of Borrower's Stock for such sale requested from the
holders in connection with the Proxy, on or before October 31, 1998, and
Borrower's failure to achieve the foregoing on or before the date set forth
above shall terminate Foothill's agreement to the forgoing forbearance from and
after the date of such failure.

                                       4

shall be deemed a part of and hereby is incorporated into the Loan Agreement.

          11.   Miscellaneous.
