                    OTHER COVENANTS OF THE NEW SHAREHOLDERS

     Section 4.1. Facilitation of the Merger. The New Shareholders jointly and
severally covenant and agree that from and after the date hereof the New
Shareholders and their Affiliates will (a) use their commercially reasonable
efforts to cooperate with and provide assistance to Parent so as to facilitate
Parent's compliance with the provisions of Section 5.8 of the Merger Agreement;
(b) refrain from taking any action which will cause the FCC or any Governmental
Authority to restrain, enjoin, or otherwise prevent or materially delay the
consummation of the Merger; and (c) use their best efforts (i) to avoid or
prevent any Action (as defined in Section 4.2) resulting in any way from the
attribution to Parent and its Affiliates of the ownership of assets of RCN
Corporation, a Delaware corporation, due to the equity interest therein held by
an Affiliate of a New Shareholder (the "RCN Interest") and (ii) to prevent the
RCN Interest from preventing or materially delaying the consummation of the
Merger beyond the Termination Date. Prior to the Effective Time, Section 4.1
governs the obligations of the New Shareholders and their Affiliates with
respect to the RCN Interest, and from and after the Effective Time, Section 4.2
shall govern such obligations. This Section 4.1 shall not apply to any assets
listed on Schedule 4.2.

     Section 4.2. Regulatory Compliance Responsibilities. In consideration for
Parent's agreement to enter into the Merger Agreement and issue Common Stock to
the New Shareholders in the Merger despite the potential for increased
regulatory complications, the New Shareholders jointly and severally covenant
and agree that from and after the date hereof:

          (a) the New Shareholders and their Affiliates will (i) sell or
     otherwise dispose of, or hold separate and agree to sell or otherwise
     dispose of, assets, categories of assets or businesses, (ii) amend or
     terminate existing relationships (including, but not limited to positional
     interests and debtor-creditor relationships) and contractual rights and
     obligations, (iii) amend or terminate existing licenses or other
     intellectual property agreements and enter into new licenses or other
     intellectual property agreements, and (iv) take any and all other action,
     if any of the foregoing is reasonably likely to be necessary for the
     purpose of avoiding or preventing any Action; provided that the foregoing
     clauses (i)-(iv) shall not apply to any assets listed on Schedule 4.2. As
     used herein, "Action" shall mean any action or inaction by the FCC or any
     Governmental Entity that (A) would adversely affect the ability of Parent
     and its Affiliates to acquire additional media properties, expand its media
     properties or enter into joint ventures or other relationships respecting
     media properties and media-related activities and (B) was caused by or
     resulted in any way from (i) the attribution to Parent and its Affiliates
     of the ownership of Non-Listed Assets of the New Shareholder and its
     Affiliates pursuant to the Communications Act which causes the Parent or
     New Shareholder to violate the FCC Rules or (ii) the ownership of
     Non-Listed Assets of the New Shareholder and its Affiliates under
     applicable federal, state and local antitrust laws or any other federal,
     state or local laws. For example, "Action" as used herein may include the
     FCC's failure to grant its consent to an application filed by Parent or an
     Affiliate of Parent seeking approval for an acquisition of new media of
     mass communication including, but not limited to, radio and television
     stations; and

          (b) the New Shareholders and their Affiliates shall take promptly, in
     the event that any permanent or preliminary injunction or other order is
     entered or becomes reasonably foreseeable to be entered in any proceeding
     that would make consummation of any agreement to which the Parent or an
     Affiliate of Parent is a party in accordance with its terms unlawful or
     that would prevent or delay consummation of such transaction, any and all
     steps (including the appeal thereof, the posting of a bond or the taking of
     the steps contemplated above) necessary to vacate, modify or suspend such


                                       7

     injunction or order so as to permit the consummation of such transaction
     prior to the deadline agreed upon by the parties to such transaction,
     provided that such injunction or order was caused by or resulted in any way
     from (x) the attribution to Parent and its Affiliates of the ownership of
     Non-Listed Assets of the New Shareholder and its Affiliates pursuant to the
     Communications Act which causes the Parent or New Shareholder or any of its
     Affiliates to violate the FCC Rules or (y) the ownership of Non-Listed
     Assets of the New Shareholder and its Affiliates under applicable federal,
     state and local antitrust laws or any other federal, state or local laws.
     The foregoing obligations of the New Shareholder and its Affiliates shall
     apply regardless of whether the conflict or violation results in whole or
     in part from actions of Parent or its Affiliates, actions of the New
     Shareholder or its Affiliates, or changes in any applicable laws.

          (c) Parent will promptly provide notice to the New Shareholders upon
     the execution of a definitive agreement for a new acquisition or other
     transaction which Parent reasonably believes will cause the New
     Shareholders or their Affiliates to incur obligations under this Section
     4.2.

     Section 4.3. Scope. The foregoing obligations in Section 4.2 shall apply
only to radio and television assets of the New Shareholders and their Affiliates
which assets are located in the United States and outdoor advertising assets of
the New Shareholders and their Affiliates which assets are located anywhere in
the world excluding South America.

     Section 4.4. Survival. This Article 4 shall survive the termination of this
Agreement for so long as the assets or actions of the New Shareholder or its
Affiliates are attributable to or deemed to be owned or taken by Parent pursuant
to attribution, control or ownership laws, rules or policies of any Governmental
Entity; provided, however, if the Merger Agreement terminates prior to the
consummation of the Merger, then this Article 4 shall terminate simultaneously
with the termination of the Merger Agreement.

     Section 4.5. Liability Under Article IV. Thomas O. Hicks, a New
Shareholder, shall not be personally liable for monetary damages arising from a
breach or violation of this Article 4 by any New Shareholder; provided, however,
all other New Shareholders shall be jointly and severally liable for any and all
losses or damages, direct or indirect, consequential or otherwise, arising from
a breach or violation of this Article 4. Except as set forth above, Thomas O.
Hicks shall not in any way be released from the obligations of the New
Shareholders hereunder.

                                 MISCELLANEOUS

     Section 6.1. Termination. Except for Article 4, which shall survive for the
period specified therein (but in no event after the termination of the Merger
Agreement), this Agreement shall terminate upon the earlier to occur of the
following: (i) the fifth anniversary of the Effective Time of the Merger, (ii)
the termination of the Merger Agreement prior to consummation of the Merger,
(iii) the agreement of the parties hereto to terminate this Agreement, or (iv)
the date on which a person or group (not including the New Shareholder, the
Existing Shareholder or their respective Affiliates) beneficially owns more than
50% of the Voting Power, whether by way of tender or exchange offer or
otherwise.

     Section 6.2. Survival. The representations and warranties herein contained
shall survive indefinitely following the termination of this Agreement, subject
to applicable statutes of limitation, if any; provided, however, that no
representations and warranties shall survive the termination of this Agreement
pursuant to Section 6.1(ii).

     Section 6.3. Specific Enforcement. The parties hereto agree that if any of
the provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached, irreparable damage would occur and it
would be extremely impracticable and difficult to measure damages. Accordingly,
in addition to any other rights and remedies to which the parties may be
entitled by law or equity, each party shall be entitled to seek specific
performance of the terms hereof. Further, the parties hereto expressly waive (a)
the defense that a remedy in damages will be adequate and (b) any requirement,
in an action for specific performance, for the posting of a bond. The New
Shareholders further agree to use their best efforts to cause their respective
partners, trustees, directors, officers, employees and agents to waive, any
requirement for the posting of a bond in connection with such remedy.

     Section 6.4. No Waiver. The parties hereby agree that no failure or delay
by a party to this Agreement, in exercising any right, power or privilege
hereunder will operate as a waiver thereof, nor will a single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any right, power or privilege hereunder.

     Section 6.5. Governing Law. This Agreement shall be governed and construed
in all respects in accordance with the laws of the State of Texas (without
giving effect to the provisions thereof relating to conflicts of law). Parent,
the Existing Shareholders, and the New Shareholders hereby consent to personal
jurisdiction in any action brought with respect to this Agreement and the
transactions contemplated hereby in the United States District Court for the
Western District of Texas sitting in Bexar County, Texas.

     Section 6.6. Successors and Assigns. Except as otherwise provided herein,
the provisions hereof shall inure to the benefit of and be binding upon, the
successors, permitted assigns, heirs, executors and administrators of the
parties hereto.

     Section 6.7. Entire Agreement; Amendment. This Agreement constitutes the
entire agreement between the parties with respect to the subject matter hereof
and supersedes all other prior agreements and understandings, both written and
oral, between the parties with respect to the subject matter hereof, and no
party shall be liable or bound to any other party in any manner by any
warranties, representations, or covenants except as specifically set forth
herein or therein. Except as expressly provided herein, neither this Agreement
nor any term hereof may be amended, waived, discharged or terminated other than
by a written instrument signed by the party against whom enforcement of any such
amendment, waiver, discharge, or termination is sought.

     Section 6.8 Interpretation. Headings of the Articles and Sections of this
Agreement are for convenience of the parties only, and shall be given no
substantive or interpretive effect whatsoever.

Agreement by any New Shareholder, including Thomas O. Hicks.

partner, director, officer, employee, member or stockholder of a New Shareholder
or an Existing Shareholder or any of their respective partners, directors,
