As used herein, the term "Non-Competition Period" shall mean the period beginning on the Closing Date and ending on the later of (x) three years after the Closing Date and (y) the date to which the Non-Competition Period shall have been from time to time extended pursuant -4- to the immediately following sentence. The Buyer shall be entitled to elect to make up to two (2) extensions of the Non-Competition Period, with each extension to be of one year's duration, such elections to be exercisable by notice to the Principal Stockholder (x) prior to three (3) years from the Closing Date in the case of the first such extension and (y) prior to four (4) years from the Closing Date in the case of the second such extension, such notice to be accompanied or preceded in each case by payment of $1.0 million by bank check or wire transfer of immediately available funds. (b) The Principal Stockholder agrees, from and after the Effective Time, that he shall not disclose or use for his own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise other than the Surviving Corporation and any of its subsidiaries or affiliates, any trade secrets, information, data, or other confidential information relating to customers, development programs, costs, marketing, trading, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans, or the business and affairs of the Surviving Corporation generally, or of any subsidiary or affiliate of the Surviving Corporation; provided that the foregoing shall not apply to information which is not unique to the Surviving Corporation or which is generally known to the industry or the public other than as a result of the Principal Stockholder's breach of this covenant. (c) If any provision contained in this Section shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Section, but this Section shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. It is the intention of the parties that if any of the restrictions or covenants contained herein is held to cover a geographic area or to be for a length of time which is not permitted by applicable law, or in any way construed to be too broad or to any extent invalid, such provision shall not be construed to be null, void and of no effect, but to the extent such provision would be valid or enforceable under applicable law, a court of competent jurisdiction shall construe and interpret or reform this Section to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained herein) as shall be valid and enforceable under such applicable law. The Principal Stockholder acknowledges that Buyer would be irreparably harmed by any -5- breach of this Section and that there would be no adequate remedy at law or in damages to compensate Buyer for any such breach.

(b) The Buyer hereby waives the provisions of the Agreement (other than Sections 2.05 and 2.06) to permit TISM to make on or prior to December 18, 1998 a distribution to its stockholders of a note receivable from the Principal Stockholder in the amount of $2,568,031.01 in payment for certain assets listed on the attached schedule. In addition, the Buyer hereby waives the provisions of the Agreement solely to the extent necessary (i) to permit certain other Stockholders of TISM to sell their Shares to the Principal Stockholder prior to the Closing, such that the ownership of the capital stock of TISM immediately prior to the Effective Time shall be as set forth on Exhibit A hereto rather than as set forth in Schedule 4.05 and (ii) to permit TISM to contribute 100% of the common stock of the Company to Domino's, Inc., a subsidiary of TISM. (c) This Amendment may be executed and delivered in any number of counterparts which together shall constitute one instrument, and shall be governed by and construed in accordance with the law of the State of New York, without regard to the conflict of law rules of such state. This Agreement shall become effective when signed and delivered by each party hereto. 10. Except as specifically amended by this Amendment, the Agreement shall remain in full force and effect.
