                      SECTION 7.  Indemnification.

                      (a)      Current Partners' Indemnities.  Each Current
Partner hereby agrees, severally and not jointly (based on such Current
Partner's respective percentage interests in the Partnerships), to indemnify,
defend and hold the LLC, SFX and each of their affiliates (collectively, the
"SFX Parties") harmless with respect to any and all demands, claims, actions,
suits, proceedings, assessments, judgments, costs, losses,


                                      -6-

<PAGE>



damages, liabilities and expenses (including, without limitation, reasonable
attorneys' fees) (collectively, the "Losses") asserted against, resulting from,
imposed upon or incurred by the LLC or SFX or its assignees directly or
indirectly relating to or arising out of the breach of any of the
representations or warranties or failure by such Current Partner to perform any
covenants or agreements of such Current Partner set forth in this Agreement or
the Related Agreements.

                      (b)  SFX's Indemnities.  SFX hereby agrees to

with respect to any and all Losses asserted against, resulting from, imposed
upon or incurred by the Current Partners directly or indirectly relating to or

or agreements of SFX set forth in this Agreement or any of the Related
Agreements.

                      (c)  Limitation on Indemnity.

                               (i)      The SFX Parties shall be entitled to
indemnification under this Agreement only to the extent that the aggregate sum
of the SFX Parties' Losses under this Agreement and the Related Agreements for
which the Current Partners are responsible hereunder individually or in the
aggregate exceeds One Hundred Fifty Thousand Dollars ($150,000) (the "Threshold
Amount")(and only to the extent of such excess). The aggregate indemnification
liability for each of the Current Partners under this Agreement shall be
limited to an amount equal to such Current Partner's allocable portion of the
Purchase Price (as defined in the Purchase and Sale Agreement) paid to such
Current Partner pursuant to Section 3.2 of the Purchase and Sale Agreement.
Notwithstanding anything to the contrary contained herein, the SFX Parties
shall not be entitled to any indemnification under this Agreement relating to
any matter disclosed in the Environmental Report (as defined in the Purchase
and Sale Agreement).

                          (ii) The Current Partners shall be entitled to
indemnification under this Agreement only to the extent that the aggregate sum
of the Current Partners' Losses under this Agreement and the Related Agreements
exceeds the Threshold Amount (and only to the extent of such excess). The
indemnification liability of SFX under this Agreement shall be limited to an
amount equal to the total Purchase Price paid to the Current Partners pursuant
to Section 3.2 of the Purchase and Sale Agreement which amount will be offset
by such amounts received by the Current Partners under the Escrow Agreement.

                      (d)  Survival of Representations and Warranties.
The Current Partners and the SFX Parties shall have the right to bring an
action for indemnification for a period of eighteen (18) months following the
Conversion Date (as defined in the SFX Convertible Note Agreement); upon the
expiration of such period, such right shall lapse and be of no further force or
effect. Notwithstanding the foregoing, the representations and warranties made
in the KAB Contribution Agreement, the Purchase and Sale Agreement and the SFX
Contribution Agreement with respect to (A) (i) title to the partnership
interests being sold or contributed thereunder and (ii) taxes shall survive the
Closing until the expiration of any applicable statutes of limitations
including any extensions thereof and shall thereupon expire together with any
right to indemnification with respect thereto and (B) environmental matters,
three (3) years from the Conversion Date.

                      (e)  Procedures.

                               (i)  Any party seeking indemnification under
this Section 7 (the "Indemnified Party") shall give the party from whom
indemnification is being sought (the "Indemnifying Party") notice of any matter
which such Indemnified Party has determined has given or could give rise to a
right of indemnification under this Agreement, within 30 days of such
determination, stating the amount of the Loss, if known, and method of
computation thereof. The obligations of an Indemnifying Party under this
Section 7 with respect to Losses arising from claims of any third party which
are subject to the indemnification provided for in this Section 7 ("Third Party
Claims") shall be governed by and contingent upon the following additional
terms and conditions: Within 30 days after receipt by an Indemnified Party of
notice of (i) any Third Party Claim or (ii) the commencement of any action or
proceeding which may entitle such Indemnified Party to indemnification under
this Section 7, such Indemnified Party shall give the Indemnifying Party
written notice of such claim or the commencement of such action or proceeding
and shall permit the Indemnifying Party to assume the defense of any such claim
or any litigation resulting from such claim. The failure to give the
Indemnifying Party timely notice under this Section 7 shall not preclude the
Indemnified Party from seeking indemnification from the Indemnifying Party
unless the Indemnifying Party has been materially prejudiced by such failure.

                          (ii)  If the Indemnifying Party assumes the
defense of any such claim or litigation resulting therefrom
with counsel reasonably acceptable to the Indemnified Party,


                                                  -8-

<PAGE>



the obligations of the Indemnifying Party as to such claim shall be limited to
assuming, in good faith, the defense of such claim or litigation and to holding
the Indemnified Party harmless from and against any losses, damages and
liabilities caused by or arising out of any settlement approved by the
Indemnifying Party or any judgment in connection with such claim or litigation
resulting therefrom; provided, however, that the Indemnified Party may
participate, at its expense, in the defense of such claim or litigation
provided that the Indemnifying Party shall direct and control the defense of
such claim or litigation. The Indemnified Party shall cooperate and make
available all books and records reasonably necessary and useful in connection
with the defense. Without the written consent of the Indemnified Party, the
Indemnifying Party shall not, in the defense of such claim or any litigation
resulting therefrom, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving
by the claimant or the plaintiff to the Indemnified Party of a release from all
liability in respect of such claim or litigation. No such claim or litigation
resulting therefrom which is being defended in good faith by the Indemnifying
Party shall be settled or compromised without the written consent of the
Indemnifying Party.

                         (iii)  If the Indemnifying Party shall not,
within 30 days of receipt of notice of any such claim or litigation, give
notice to the Indemnified Party of its intention to assume the defense of any
such claim or litigation resulting therefrom, the Indemnified Party may, but
shall have no obligation to, defend against such claim or litigation, acting in
good faith and in such manner as it may deem appropriate, and the Indemnified
Party may compromise or settle such claim or litigation without the
Indemnifying Party's consent. The Indemnifying Party shall promptly pay any
such settlement of such claim or litigation and shall also promptly reimburse
the Indemnified Party for the amount of all reasonable expenses, legal or
otherwise, incurred by the Indemnified Party in connection with the defense
against or settlement of such claim or litigation. In addition, the
Indemnifying Party shall promptly pay the amount of any judgment rendered with
respect to such claim or in such litigation.

                      (f)      Sole Remedy.  The indemnification provided in
this Section 7 shall be the sole and exclusive post-Closing remedy available to
any party with respect to any claims relating to this Agreement, the Purchase
and Sale Agreement, the KAB Contribution Agreement, the SFX Contribution
Agreement


                                      -9-

and the SFX Convertible Note Agreement. In furtherance of the foregoing, the
parties (on behalf of themselves and their respective affiliates, directors,
officers, employees, agents, successors and assigns) hereby waive from and
after the date of the Closing, to the fullest extent permitted under applicable
law, any and all rights, claims and causes of action they may have against any
other party relating to the subject matter of this Agreement or any of the
other agreements referred to in the preceding sentence arising under or based
upon any federal, state, local or foreign law, rule or regulation (including,
without limitation, any law, rule or regulation relating to environmental
matters).

                      SECTION 8. Rich LMA.  The parties hereto contemplate
that there may be entered into a Local Marketing Agreement ("Rich LMA") between
the Partnerships and the LLC with respect to the Rich Stations. The parties
hereby acknowledge and agree that the Rich LMA shall be in a form satisfactory
to SFX, the LLC and the Partnerships.

                      SECTION 9.  Consequential Damages.  Notwithstanding
any provision contained herein, in the event that an arbitrator under the
Escrow Agreement determines that any Party shall have acted in bad faith in
connection with any of the Contemplated Transactions, any other Party who has
incurred a Loss may seek as one of its damages consequential damages.

                      SECTION 10.  Restriction on Consents, Amendments,
Waivers and Modifications; Opinions. The LLC hereby agrees not to amend, waive
or modify any term or condition set forth in any Related Agreement or in any
other agreement contemplated hereby to which the LLC is a Party (or consent to
any change requested thereunder) without the prior written consent of SFX. In
addition, the LLC hereby agrees that any and all forms of opinions to be
delivered to the LLC under any of the Related Agreements shall be in a form
reasonably satisfactory to SFX.

                      SECTION 11.  Restriction on Sale of Stations.  While
the Purchase and Sale Agreement is in effect, each of (i) ABS, KAB and the LLC
(with respect to the Benchmark Stations) and (ii) EBFI, EBFP, RICH-I and
RICH-II (with respect to the Rich Stations) hereby agree that such Party shall
not sell, transfer or otherwise encumber any of the Benchmark Stations or the
Rich Stations, as applicable, without the prior written approval of SFX, other
than as part of the Contemplated Transactions.
