     and covenants contained in Section 9.a of the Securities Purchase and
     Exchange Agreement, as amended by this Fourth Amendment, to and with the
     Company as of the date hereof. For purposes of the representations made by
     the Snider Co-Investors pursuant to Section 9.a of the Securities Purchase
     and Exchange Agreement and this Section 4 the term "Agreement" shall mean
     this Fourth Amendment and the term "Other Documents" shall mean the Merger
     Agreements and the other agreements contemplated by the Merger Agreements.
     T. Snider hereby certifies that he is an accredited investor, as that term
     is defined in Regulation D, Section 501 of the Securities Act. Each of the
     Snider Co-Investors represents and warrants that he or she is
     sophisticated in financial matters and is able to evaluate the risks and
     benefits of the Investor Stock being acquired by him or her. Each of the
     Snider Co-Investors understands that the Investor Stock being acquired by
     him or her is being delivered in reliance on exemptions from the
     registration requirements of federal and state securities laws and that
     the Company is relying upon the truth and accuracy of the representations,
     warranties, agreements, and acknowledgments of the Snider Co-Investors set
     forth herein to determine each such Investor's suitability to acquire the
     Investor Stock being acquired by him or her. Each of the Snider
     Co-Investors is acquiring the Investor Stock for such Investor's own
     accounts without a view to public distribution and, except as contemplated
     by this Agreement, the Other Documents and the Seventh Amended and
     Restated Certificate of Incorporation, such Investor has no contract,
     undertaking, agreement or arrangement to transfer, sell or otherwise
     dispose of any Investor Stock or any interest therein to any Person.

          5. Schedule 14. Each of the Snider Co-Investors represents and
     warrants that following the Contemplated Transactions to which he or she
     is a party, except as set forth in Schedule 14 to the Securities Purchase
     and Exchange Agreement, as amended as of the date hereof, attached to this
     Fourth Amendment as Schedule 14, he or she does not own in excess of 5
     percent (5%) of the voting stock in, or serve as an officer or director
     of, any company engaged in the ownership or operation of one or more radio
     stations, television stations or daily newspapers, or serve as a general
     partner in any partnership engaged in the ownership or operation of one or
     more radio stations, television stations or daily newspapers. Each of the
     Snider Co-Investors represents and warrants that the information contained
     in Schedule 14 is complete and accurate.

          6. Notice. All notices and other communications provided for or
     permitted under the Securities Purchase and Exchange Agreement shall be

          7. Incorporation of Recitals. The Recitals set forth in this Fourth
     Amendment are incorporated herein.

          8. Choice of Law. It is the intention of the parties that the
     internal laws, and not the laws of conflicts, of Arizona should govern the
     enforceability and validity of this Fourth Amendment, the construction of
     its terms and the interpretation of the rights and duties of the parties;
     provided, however, that the laws of the State of Nevada shall govern the
     relationship between the Company and its stockholders.

          9. Counterparts. This Fourth Amendment may be executed in any number
     of counterparts and by different parties hereto in separate counterparts,
     with the same effect as if all parties had signed the same document. All
     such counterparts shall be deemed an original, shall be construed together
     and shall constitute one and the same instrument.

          IN WITNESS WHEREOF, the undersigned have caused this Amendment to be
     duly executed and delivered by their respective duly authorized officers
     on the day and year first above written.
