In no event will the Company be required to net cash settle the Warrant exercise."

        2.7    Replacement of Securities Upon Reorganization, etc.    Section 4.4 of the Existing Warrant Agreement is hereby amended to delete the following language:

        "provided further, however, that if more than 30% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in the form of common stock in the successor entity that is not listed for trading on a national securities exchange or on the OTC Bulletin Board, or is not to be so listed for trading immediately following such event, then the Warrant Price shall be reduced by an amount (in dollars) equal to the quotient of (x) $18.00 (subject to adjustment in accordance with Section 6.1 hereof) minus the Per Share Consideration (as defined below) (but in no event, less than zero), and (y) if the applicable event is announced on or prior to the third anniversary of the closing date of the initial Business Combination, 2; if the applicable event is announced after the third anniversary of the closing date of the initial Business Combination and on or prior to the fourth anniversary of the closing date of the initial Business Combination, 2.5; if the applicable event is announced after the fourth anniversary of the closing date of the initial Business Combination and on or prior to the Expiration Date, 3.

The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers."

        "4.6    No Fractional Shares.    Notwithstanding any provision contained in this Warrant Agreement to the contrary, the Company shall not issue fractional shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4 after the Effective Time (as defined in the Merger Agreement), the holder of any Warrant would be entitled, upon the exercise of such Warrant (which, for the avoidance of doubt, is required to be exercised only for an even number of Warrants), to receive a fractional interest in a share, the Company shall, upon such exercise, at its option either (i) round up to the nearest whole number, the number of the shares of Common Stock to be issued to such holder or (ii) in lieu of such fractional share interests, pay to such holder an amount in cash equal to the product obtained by multiplying (x) the fractional share interest to which such holder would otherwise be entitled by (y) the Fair Market Value on the exercise date. Solely for purposes of this Section 4.6, "Fair Market Value" shall mean the average last sale price of the Common Stock

5

for the ten (10) trading days ending on the trading day prior to the date on which notice of exercise of the Warrant is sent to the Warrant Agent."

        "6.5    Mandatory Cash Distribution.    Notwithstanding anything contained in this Agreement to the contrary, at the Effective Time (as defined in the Merger Agreement), each Warrant issued and outstanding immediately prior to the Effective Time shall, automatically and without any action by the Registered Holder thereof, be entitled to receive a cash distribution payable by or at the direction of Parent as soon as reasonably practicable following the Effective Time, but no later than three (3) Business Days following the date on which the Effective Time occurs, in the amount of $0.50."

        2.10    Registration of Common Stock.    Section 7.4 of the Existing Warrant Amendment is hereby amended and restated in its entirety as follows:

        "7.4    Registration of Common Stock.    The Company may, but shall not be required to, file with the Commission a new registration statement for the registration under the Securities Act of the Common Stock issuable upon exercise of the Warrants. If the Company shall elect to file such new registration statement, it shall use its commercially reasonable efforts to take such action as is necessary to register or qualify for sale, in those states in which the Warrants were initially offered by the Company, the Common Stock issuable upon exercise of the Warrants, to the extent an exemption is not available. In such event, the Company shall use its commercially reasonable efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the earlier of (x) the expiration of the Warrants in accordance with the provisions of this Agreement and (y) the date the Company shall determine to suspend such effectiveness or withdraw such registration statement. If the Company shall have filed a new registration statement following the closing of the Business Combination and such registration statement has not been declared effective by the 60th Business Day after the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the 61st Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall otherwise not have an effective registration statement covering the Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a "cashless basis," as provided below. If the Company shall not have filed a new registration statement within 30 days following the closing of the Business Combination, holders of the Warrants shall have the right, beginning on the 31st day following the closing of the Business Combination, to exercise such Warrants on a "cashless basis," as provided below. Holders may exercise warrants on a "cashless basis" by exchanging the Warrants (in accordance with Section 3(a)(9) of the Act or another exemption) for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant Price and the Fair Market Value (as defined below) by (y) the Fair Market Value. Solely for purposes of this Section 7.4, "Fair Market Value" shall mean the volume weighted average price of the Common Stock as reported during the ten trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. The Company shall provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a cashless basis in accordance with this Section 7.4 is not

6

required to be registered under the Securities Act and (ii) the Common Stock issued upon such exercise shall be freely tradable under the United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and , accordingly, shall not be required to bear a restrictive legend. If, by reason of any exercise of warrants on a "cashless basis", the holder of any Warrant would be entitled, upon the exercise of such Warrant (which, for the avoidance of doubt, is required to be exercised only for an even number of Warrants), to receive a fractional interest in a share, the Company shall, upon such exercise, at its option either (i) round up to the nearest whole number, the number of the shares of Common Stock to be issued to such holder or (ii) in lieu of such fractional share interests, pay to such holder an amount in cash equal to the product obtained by multiplying (x) the fractional share interest to which such holder would otherwise be entitled by (y) the Fair Market Value on the exercise date."

        3.    Miscellaneous Provisions.    

        3.1    Effectiveness of Warrant.    Each of the parties hereto acknowledges and agrees that the effectiveness of this Agreement shall be expressly subject to the occurrence of the Azteca Merger (as defined in the Merger Agreement) and shall automatically be terminated and shall be null and void if the Merger Agreement shall be terminated for any reason.

        3.2    Successors.    All the covenants and provisions of this Agreement by or for the benefit of the Company, Parent or the Warrant Agent shall bind and inure to the benefit of their respective successors and assigns.

        3.3    Applicable Law.    The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum.

        3.4    Counterparts.    This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

        3.5    Effect of Headings.    The section headings herein are for convenience only and are not part of this Warrant Agreement and shall not affect the interpretation thereof.

        3.6    Severability.    This Warrant Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Warrant Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Warrant Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

        3.7    Entire Agreement.    The Existing Warrant Agreement, as modified by this Agreement, constitutes the entire understanding of the parties and supersedes all prior agreements, understandings, arrangements, promises and commitments, whether written or oral, express or implied, relating to the subject matter hereof, and all such prior agreements, understandings, arrangements, promises and commitments are hereby canceled and terminated.
