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, 36^th 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:

(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).

(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

	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

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

requirements of Rule 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.
