    as amended, supplemented or otherwise modified from time to time (including
    pursuant to that certain letter agreement, dated as of April 5, 2004, between
    the Company and DCC), this Warrant may be exercised, in whole or in part,
    by the Warrantholder by: 

	
	 
	 	       (a)
        the surrender of this Warrant to the Company, with a duly executed Exercise
        Form specifying the number of Warrant Shares to be purchased, during
        normal business hours on any Business Day prior to the Expiration Date;
        and 

           (b) the
        delivery of payment to the Company, for the account of the Company, by
        cash, by certified or bank cashier's check or by wire transfer of immediately
        available funds in accordance with wire instructions that shall be provided
        by the Company upon request, of the Exercise Price for the number of
        Warrant Shares specified in the Exercise Form in lawful money of the
    United States of America.
	 




The Company agrees that such Warrant Shares shall be deemed to be issued to the Warrantholder as the record holder of such Warrant Shares as of the close of business on the date on which this Warrant shall have been surrendered
and payment made for the Warrant Shares as aforesaid. 


      1.2 Limitations on Exercise. Notwithstanding anything to the contrary herein, this Warrant may be exercised only upon (i) the delivery to the Company of any certificates,
legal opinions, and other documents reasonably requested by the Company to satisfy the Company that the proposed exercise of this Warrant may be effected without registration under the Securities Act, (ii) receipt by the Company of FCC approval of
the proposed exercise, if such approval is required (as determined by a written opinion of the Company's special FCC counsel, delivered to the Warrantholder) to maintain any license granted to the Company by the FCC, or to maintain the Company's
eligibility for any FCC license for which it has applied, or reasonably expects to apply, for, (iii) in the event that the acquisition of the Warrant Shares is subject to the provisions of the HSR Act, any person or entity required to file a
notification and report in compliance with the HSR Act shall have filed such form and the applicable waiting period with respect to such form (including any extension thereof by reason of a request for additional information) shall have expired or
been terminated, and (iv) receipt by the Company of approval of any other applicable Governmental Authority of the proposed exercise. The Warrantholder shall not be entitled to exercise this Warrant, or any part thereof, unless and until such
approvals, certificates, legal opinions or other documents are reasonably acceptable to the Company. The cost of such approvals, certificates, legal opinions and other documents, if required, shall be borne by the Warrantholder.

 1.3 Warrant Shares Certificate. A stock certificate or certificates for the Warrant Shares specified in the Exercise Form shall be delivered to the Warrantholder within
five Business Days after receipt of the Exercise Form and receipt of payment of the purchase price. If this Warrant shall have been exercised only in part, the Company shall, at the time of delivery of the stock certificate or certificates, deliver
to the Warrantholder a new Warrant evidencing the rights to purchase the remaining Warrant Shares, which new Warrant shall in all other respects be identical with this Warrant. 


        1.4 Payment of Taxes. The issuance of certificates for Warrant Shares shall be made without charge to the Warrantholder for any documentary, stamp or similar stock
transfer or other issuance tax in respect thereto; provided that the Warrantholder shall be required to pay any and all taxes which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the then Warrantholder as reflected upon the books of the Company. 


        1.5 Divisibility of Warrant; Transfer of Warrant. (a) This Warrant may only be transferred by the Warrantholder with the prior written consent of the Company;
provided that the Warrantholder shall have the right to transfer this Warrant to any wholly-owned subsidiary of the original Warrantholder. Except as set forth above, any transfer of this
Warrant without the prior written consent of the Company shall be void and of no force and effect.


        (b) Subject to the provisions of this Section, this Warrant may be divided into warrants of one thousand shares or multiples thereof, upon surrender at the office of the Company located at 1221 Avenue of the Americas,
36th Floor, New York, New York 10020, without charge to any Warrantholder. Subject to the provisions of this Section, upon such division, the Warrants may be transferred of record as the
then Warrantholder may specify without charge to such Warrantholder (other than any applicable transfer taxes).


        (c) Subject to the provisions of this Section 1.5, upon surrender of this Warrant to the Company with a duly executed Assignment Form and funds sufficient to pay any transfer tax, the Company shall, without charge, execute and
deliver a new Warrant or Warrants of like tenor in the name of the assignee named in such Assignment Form, and this Warrant shall promptly be canceled. Prior to any proposed transfer (whether as the result of a division or otherwise) of this
Warrant, the Warrantholder shall give written notice to the Company of the Warrantholder's intention to effect such transfer. Each such notice shall describe the manner and circumstances of the proposed transfer in sufficient detail, and, if
requested by the Company, shall be accompanied by a written opinion of legal counsel, which opinion shall be addressed to the Company and be reasonably satisfactory in form and substance to the Company, to the effect that the proposed transfer of
this Warrant may be effected without registration under the Securities Act. In addition to the restrictions contained in this Section, the Warrantholder shall not be entitled to transfer this Warrant, or any part thereof, if such legal opinion is
not reasonably acceptable to the Company. The term “Warrant” as used in this Agreement shall be deemed to include any Warrants issued in substitution or exchange for this Warrant.

        2. Restrictions on Transfer; Restrictive Legends. Except as otherwise permitted by this Section 2, each Warrant shall (and each Warrant issued upon direct or indirect
transfer or in substitution for any Warrant pursuant to Section 1.5 or Section 4 shall) be stamped or otherwise imprinted with a legend in substantially the following form: 

	 	       THIS
          WARRANT AND ANY SECURITIES ACQUIRED UPON THE EXERCISE OF THIS WARRANT
          HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
          OR ANY STATE SECURITIES LAWS AND NEITHER THIS WARRANT NOR SUCH SECURITIES
          NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED
          OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
          STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION
          UNDER SUCH ACT AND SUCH LAWS. 

    



Except as otherwise permitted by this Section 2, each stock certificate for Warrant Shares issued upon the exercise of any Warrant and each stock certificate issued upon the direct or indirect transfer of any such Warrant Shares
shall be stamped or otherwise imprinted with a legend in substantially the following form: 


	 	       THE
          SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
          LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED,
          SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT
          TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS
          OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS.




        Notwithstanding the foregoing, the Warrantholder may require the Company to issue a Warrant or a stock certificate for Warrant Shares, in each case without a legend, if either (i) such Warrant or such Warrant Shares, as the case
may be, have been registered for resale under the Securities Act or (ii) the Warrantholder has delivered to the Company an opinion of legal counsel, which opinion shall be addressed to the Company and be reasonably satisfactory in form and substance
to the Company, to the effect that such registration is not required with respect to such Warrant or such Warrant Shares, as the case may be.


        By acceptance of this Warrant, the Warrantholder expressly agrees that it will at all times comply with the restrictions contained in Rule 144(e) under the Securities Act (as in effect on the date hereof) when selling,
transferring or otherwise disposing Warrant Shares, even if such restrictions would not then be applicable to the Warrantholder.


        3. Reservation and Registration of Shares. The Company covenants and agrees as follows: 












5

	 	       (a)
          all Warrant Shares which are issued upon the exercise of this Warrant
          will, upon issuance, be validly issued, fully paid, and nonassessable,
          not subject to any preemptive rights, and free from all taxes, liens,
          security interests, charges, and other encumbrances with respect to
          the issue thereof, other than taxes with respect to any transfer occurring
          contemporaneously with such issue; 

               (b) during the period within which
          this Warrant may be exercised, the Company will at all times have authorized
          and reserved, and keep available free from preemptive rights and any
          liens and encumbrances, a sufficient number of shares of Common Stock
          to provide for the exercise of the rights represented by this Warrant;
          and 

               (c) it will, from time to time, take
          all such action as may be required to assure that the par value per
          share of the Warrant Shares is at all times equal to or less than the
          then effective Exercise Price. 




        4. Loss or Destruction of Warrant. Subject to the terms and conditions hereof, upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, of such bond or indemnification as the Company may reasonably require, and, in the case of such mutilation, upon surrender and cancellation of this Warrant,
the Company will execute and deliver a new Warrant of like tenor. 


        5. Ownership of Warrant. The Company may deem and treat the Person in whose name this Warrant is registered as the holder and owner hereof (notwithstanding any notations
of ownership or writing hereon made by anyone other than the Company) for all purposes and shall not be affected by any notice to the contrary, until presentation of this Warrant for registration of transfer. 

       6. Certain
Adjustments.


       6.1 The number of Warrant Shares purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment as follows:


	 	       (a) Stock
            Dividends. If at any time after the
            date of the issuance of this Warrant (i) the Company shall fix a
            record date for the issuance of any stock dividend payable in shares
            of Common Stock; or (ii) the number of shares of Common Stock shall
            have been increased by a subdivision or split-up of shares of Common
            Stock, then, on the record date fixed for the determination of holders
            of Common Stock entitled to receive such dividend or immediately
            after the effective date of such subdivision or split-up, as the
            case may be, the number of shares to be delivered upon exercise of
            this Warrant shall be increased so that the Warrantholder shall be
            entitled to receive the number of shares of Common Stock that such
            Warrantholder would have owned immediately following such action
            had this Warrant been exercised immediately prior thereto, and the
            Exercise Price shall be adjusted as provided below in paragraph (g). 

    












6

	 	       (b) Combination
            of Stock. If the number of shares of
            Common Stock outstanding at any time after the date of the issuance
            of this Warrant shall have been decreased by a combination of the
            outstanding shares of Common Stock, then, immediately after the effective
            date of such combination, the number of shares of Common Stock to
            be delivered upon exercise of this Warrant shall be decreased so
            that the Warrantholder thereafter shall be entitled to receive the
            number of shares of Common Stock that such Warrantholder would have
            owned immediately following such action had this Warrant been exercised
            immediately prior thereto, and the Exercise Price shall be adjusted
            as provided below in paragraph (g). 

               (c) Reorganization.
          If any capital reorganization of the Company, any reclassification
          of the Common Stock, any consolidation of the Company with or merger
          of the Company with or into any other Person, or any sale or lease
          or other transfer of all or substantially all of the assets of the
          Company to any other Person, shall be effected in such a way that the
          holders of Common Stock shall be entitled to receive stock, other securities
          or assets (whether such stock, other securities or assets are issued
          or distributed by the Company or another Person) with respect to or
          in exchange for Common Stock, then, upon exercise of this Warrant,
          the Warrantholder shall have the right to receive the kind and amount
          of stock, other securities or assets receivable upon such reorganization,
          reclassification, consolidation, merger or sale, lease or other transfer
          by a holder of the number of shares of Common Stock that such Warrantholder
          would have been entitled to receive upon exercise of this Warrant had
          this Warrant been exercised immediately before such reorganization,
          reclassification, consolidation, merger or sale, lease or other transfer,
          subject to adjustments that shall be as nearly equivalent as may be
          practicable to the adjustments provided for in this Section 6. The
          Company shall not effect any such consolidation, merger or sale, lease
          or other transfer, unless prior to, or simultaneously with, the consummation
          thereof, the successor Person (if other than the Company) resulting
          from such consolidation or merger, or such Person purchasing, leasing
          or otherwise acquiring such assets, shall assume, by written instrument,
          the obligation to deliver to the Warrantholder the shares of stock,
          securities or assets to which, in accordance with the foregoing provisions,
          the Warrantholder may be entitled and all other obligations of the
          Company under this Warrant. The provisions of this paragraph (c) shall
          apply to successive reorganizations, reclassifications, consolidations,
          mergers, sales, leasing transactions and other transfers. 

               (d) Distributions
            to all Holders of Common Stock. If
            the Company shall, at any time after the date of issuance of this
            Warrant, fix a record date to distribute to all holders of its Common
            Stock any shares of capital stock of the Company (other than Common
            Stock) or evidences of its indebtedness or assets (not including
            regular quarterly cash dividends and distributions paid from retained
            earnings of the Company) or rights or warrants to subscribe for or
            purchase any of its securities, then the Warrantholder shall be entitled
            to receive, upon exercise of this Warrant, that portion of such distribution
            to which it would have been entitled had the Warrantholder exercised
            its Warrant immediately prior to the date of such distribution. At
            the time it fixes the record date for 



 











7

 

	 	such distribution, the
          Company shall allocate sufficient reserves to ensure the timely and
          full performance of the provisions of this Subsection. The Company
          shall promptly (but in any case no later than
          five Business Days prior to the record date of such distribution) give
          notice to the Warrantholder that such distribution will take place. 

               (e) Fractional
            Shares. No fractional shares of Common
            Stock or scrip shall be issued to any Warrantholder in connection
            with the exercise of this Warrant. Instead of any fractional shares
            of Common Stock that would otherwise be issuable to such Warrantholder,
            the Company shall pay to such Warrantholder a cash adjustment in
            respect of such fractional interest in an amount equal to that fractional
            interest of the then current Fair Market Value per share of Common
            Stock. 

               (f) Carryover.
          Notwithstanding any other provision of this Section 6, no adjustment
          shall be made to the number of shares of Common Stock to be delivered
          to the Warrantholder (or to the Exercise Price) if such adjustment
          represents less than 1% of the number of shares to be so delivered,
          but any lesser adjustment shall be carried forward and shall be made
          at the time and together with the next subsequent adjustment which
          together with any adjustments so carried forward shall amount to 1%
          or more of the number of shares to be so delivered. 

               (g) Exercise
            Price Adjustment. Whenever the number
            of Warrant Shares purchasable upon the exercise of this Warrant is
            adjusted, as herein provided, the Exercise Price payable upon the
            exercise of this Warrant shall be adjusted by multiplying such Exercise
            Price immediately prior to such adjustment by a fraction, of which
            the numerator shall be the number of Warrant Shares purchasable upon
            the exercise of the Warrant immediately prior to such adjustment,
            and of which the denominator shall be the number of Warrant Shares
            purchasable immediately thereafter. 

        

    
	 
	       6.2 Rights Offering.
        In the event the Company shall effect an offering of Common Stock or
        preferred stock among its stockholders, the Warrantholder shall be entitled
        to elect to participate in each and every such offering as if this Warrant
        had been exercised immediately prior to each such offering. The Company
        shall promptly (but in any case no later than five Business Days prior
        to such rights offering) give notice to the Warrantholder that such rights
        offering will take place. The Company shall not be required to make any
        adjustment pursuant to Section 6.1 with respect to the issuance of shares
        of Common Stock or preferred stock pursuant to a rights offering in which
        the holder hereof is offered the right to participate under the provisions
    of this Section 6.2. 
	 	 
	
               6.3 Notice
            of Adjustments. Whenever the number
            of Warrant Shares or the Exercise Price is adjusted pursuant to Section
            6.1, the Company shall promptly give to the Warrantholder notice
            of such adjustment or adjustments and a certificate of a firm of
            independent public accountants of recognized national standing (which
            shall be appointed at the Company's expense and may be the independent
            public accountants regularly employed by the Company) setting forth
            the number of Warrant Shares and the Exercise Price of such Warrant
    Shares after such 



 











8


 adjustment, a brief statement of the facts requiring
            such adjustment, and the computation by which such adjustment was
made. 


       6.4 Notice of Extraordinary Corporate Events. In case the Company after the date hereof shall propose to (i) distribute any dividend (whether stock or cash or otherwise)
    to the holders of shares of Common Stock or to make any other distribution to the holders of shares of Common Stock, (ii) offer to the holders of shares of Common Stock rights to subscribe for or purchase any additional shares of any class of stock
    or any other rights or options, or (iii) effect any reclassification of the Common Stock (other than a reclassification involving merely the subdivision or combination of outstanding shares of Common Stock), any capital reorganization, any
    consolidation or merger (other than a merger in which no distribution of securities or other property is to be made to holders of shares of Common Stock), any sale or lease or transfer or other disposition of all or substantially all of its
    property, assets and business, or the liquidation, dissolution or winding up of the Company, then, in each such case, the Company shall give to the Warrantholder notice of such proposed action, which notice shall specify the date on which (a) the
    books of the Company shall close, or (b) a record shall be taken for determining the holders of Common Stock entitled to receive such stock dividends or other distribution or such rights or options, or (c) such reclassification, reorganization,
    consolidation, merger, sale, transfer, other disposition, liquidation, dissolution or winding up shall take place or commence, as the case may be, and the date, if any, as of which it is expected that holders of record of Common Stock shall be
    entitled to receive securities or other property deliverable upon such action. Such notice shall be given in the case of any action covered by clause (i) or (ii) above at least ten days prior to the record date for determining holders of Common
    Stock for purposes of receiving such payment or offer, or in the case of any action covered by clause (iii) above at least 30 days prior to the date upon which such action takes place and 20 days prior to any record date to determine holders of
    Common Stock entitled to receive such securities or other property. 


        6.5 Effect of Failure to Notify. Failure to file any certificate or notice or to give any notice, or any defect in any certificate or notice, pursuant to Sections 6.3 and
6.4 shall not affect the legality or validity of the adjustment to the Exercise Price, the number of shares purchasable upon exercise of this Warrant, or any transaction giving rise thereto. 


        7. Reports Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the Holders to sell securities of the Company to the public without registration (“Rule 144”), the Company
agrees to: 

	 	       (a) make and keep public information
          available, as those terms are understood and defined in Rule 144, at
          all times; 

               (b) file with the SEC in a timely
          manner all reports and other documents required of the Company under
          the Securities Act and the Exchange Act; and 

               (c)
          furnish to each Holder so long as such Holder owns Warrants, promptly
          upon request, (i) a written statement by the Company that it has complied
    with the reporting

          144, the Securities Act and the Exchange Act, (ii) a copy of the most
          recent annual or quarterly report of the Company and such other reports
          and documents so filed by the Company, and (iii) such other information
          as may be reasonably requested to permit the Holders to sell such securities
          without registration. 

    


       8. Amendments. Any provision of this Warrant may be amended and the observance thereof may be waived (either generally or in a particular instance and either
  retroactively or prospectively), only with the written consent or approval of the Company and the Holders who hold a majority in interest of the Warrants; provided that it is not necessary
  that the exact form of the amendment be approved by the holders of a majority in interest of the Warrants if such holders have approved the substance of such amendment. Any amendment or waiver effected in accordance with this Section 8 shall be
  binding upon each Holder and the Company. 


        9. Expiration of the Warrant. The obligations of the Company pursuant to this Warrant shall terminate on the Expiration Date.

          or other material agreement of the Company or the Certificate of Incorporation
    or Bylaws.

          have been duly authorized and reserved for issuance. When issued, such

            executed and delivered by the Company and constitutes the legal,
            valid and binding obligation of the Company enforceable against the
