CONTENTS

Tikcro Technologies Ltd.

Capitalized terms used but not defined herein shall have the definitions ascribed to them in the Rights Plan.

The Company entered as of February 1, 2013 into an agreement with Mr. Steven Bronson (the "Agreement"), pursuant to which Mr. Bronson undertook to maintain the confidentiality of non-public information that the Company may provide to him about its business.  Mr. Bronson also undertook not to be the beneficial owner of more than 1,500,094 ordinary shares of the Company and not to vote more than 1,334,829 ordinary shares of the Company, or 14.99% of the Company's outstanding ordinary shares.  The Company undertook to postpone the Distribution Date under the Rights Plan for 30 Business Days following the termination of the Agreement.  The Agreement will be in effect until either of the parties terminates it.
