(b) In case the Company shall at any time effect a Sale or Merger Transaction in which the consideration to be received by the Company or its stockholders consists in part of consideration other than cash, the Holder of this Warrant shall have the right thereafter to 3 purchase, by exercise of this Warrant and payment of the aggregate Exercise Price in effect immediately prior to such action, the kind and amount of shares and other securities and property which it would have owned or have been entitled to receive after the happening of such transaction had this Warrant been exercised immediately prior thereto. (c) "Piggy-Back" Registration. The Holder of this Warrant shall have the right to include all of the shares of Common Stock underlying this Warrant (the "Registrable Securities") as part of any registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to Form S-8) and must be notified in writing of such filing; provided, however, that the holder of this Warrant agrees it shall not have any piggy-back registration rights pursuant to this Section 12(c) if the shares of Common Stock underlying this Warrant are freely tradable in the United States pursuant to the provisions of Regulation D. Holder shall have five (5) business days to notify the Company in writing as to whether the Company is to include Holder or not include Holder as part of the registration; provided, however, that if any registration pursuant to this Section shall be underwritten, in whole or in part, the Company may require that the Registrable Securities requested for inclusion pursuant to this Section be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. If purchase, by exercise of this Warrant and payment of the aggregate Exercise Price in effect immediately prior to such action, the kind and amount of shares and other securities and property which it would have owned or have been entitled to receive after the happening of such transaction had this Warrant been exercised immediately prior thereto. (c) "Piggy-Back" Registration. The Holder of this Warrant shall have the right to include all of the shares of Common Stock underlying this Warrant (the "Registrable Securities") as part of any registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to Form S-8) and must be notified in writing of such filing; provided, however, that the holder of this Warrant agrees it shall not have any piggy-back registration rights pursuant to this Section 12(c) if the shares of Common Stock underlying this Warrant are freely tradable in the United States pursuant to the provisions of Regulation D. Holder shall have five (5) business days to notify the Company in writing as to whether the Company is to include Holder or not include Holder as part of the registration; provided, however, that if any registration pursuant to this Section shall be underwritten, in whole or in part, the Company may require that the Registrable Securities requested for inclusion pursuant to this Section be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. If in the good faith judgment of the underwriter evidenced in writing of such offering only a limited number of Registrable Securities should be included in such offering, or no such shares should be included, the Holder, and all other selling stockholders, shall be limited to registering such proportion of their respective shares as shall equal the proportion that the number of shares of selling stockholders permitted to be registered by the underwriter in such offering bears to the total number of all shares then held by all selling stockholders desiring to participate in such offering. Those Registrable Securities which are excluded from an underwritten offering pursuant to the foregoing provisions of this Section (and all other Registrable Securities held by he selling stockholders) shall be withheld from the market by the Holders thereof for a period, not to exceed one hundred eighty (180) days, which the underwriter may reasonably determine is necessary in order to effect such underwritten offering. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 12(c) prior to the effectiveness of such registration whether or not any Warrant holder elected to include securities in such registration.

Such notice, in absence of manifest error, shall be conclusive evidence of the correctness of such adjustment. 16. Authorized Shares.
