If TLC shall effect a subdivision or consolidation of shares or other capital readjustment, the payment of a stock dividend, or other increase or reduction of the number of shares of the common stock outstanding, without receiving compensation therefor in money, services or -2- property, then (1) the number, class, and per share price of shares of common stock to be exchanged hereunder shall be appropriately adjusted in such a manner as to entitle Speaker to receive upon exercise of an Option, for the same aggregate cash consideration, the same total number and class of shares as he would have received had Speaker exercised his Option in full immediately prior to the event requiring the adjustment; and (2) the number and class of shares then reserved for issuance hereunder as a result of Options outstanding shall be adjusted by substituting for the total number and class of shares of common stock then reserved that number and class of shares of common stock that would have been received by the owner of an equal number of outstanding shares of each class of common stock as the result of the event requiring the adjustment. c. After a merger of one or more corporations with TLC or after a consolidation of TLC and one or more corporations, Speaker shall, at no additional cost, be entitled upon exercise of an Option to receive pursuant to this Agreement in lieu of the number and class of shares as to which he would be entitled to exchange pursuant to paragraph 2 hereof, the number and class of shares of stock or other securities to which Speaker would have been entitled pursuant to the terms of the agreement of merger or consolidation if, immediately prior to such merger or consolidation, Speaker had been the holder of record of the number and class of shares of common stock equal to the number and class of shares as to which he would be entitled under paragraph 2 hereof. d. Except as previously expressly provided, neither the issuance by TLC of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of TLC convertible into such shares or other securities, nor the increase or decrease of the number of authorized shares of stock, nor the addition or deletion of classes of stock, shall affect, and no adjustment by reason thereof shall be made with respect to, the number, class or price of shares of common stock then subject to this Agreement. e. Adjustment under the preceding provisions of this section will be made by the Board of Directors of TLC in good faith, whose determination as to what adjustments will be made and the extent thereof will be final, binding, and conclusive. 5. Authorization and Reservation of Shares. During the term of this Agreement, TLC will at all times have authorized and reserved a sufficient number of shares of its common stock to provide for the rights to exchange as provided for herein. TLC represents and warrants that (i) all stock issued to Speaker in -3- exchange for 20/20 stock shall be validly issued, fully paid and non-assessable, and (ii) such stock shall be free of restrictions on transferability imposed by TLC other than the provisions of paragraph 8 hereof and the terms and conditions of the Holdback Agreement (defined in paragraph 8), provided however, that, subject to the provisions of paragraph 7 hereof and the terms and conditions of the Registration Rights Agreement (defined in paragraph 7), such stock may be subject to restrictions on transferability imposed by applicable law. 6.
