         and directed the issuance of one Right with respect to each Common

                  (m) "OFFEROR" shall have the meaning set forth in Section
         1(j).";

                  (n) "MERGER AGREEMENT" shall have the meaning set forth in
         Section 1(j)."; and

                  (o) "TENDER OFFER DATE" shall have the meaning set forth in
         Section 7(a)."

         C. AMENDMENT TO SECTIONS 3(b) & (c). Sections 3(b) & (c) of the Rights

         in substantially the form of Exhibit C (the "SUMMARY OF RIGHTS"), by
         first-class, postage-prepaid mail, to each record holder of Common
         Shares as of the Close of Business on the Record Date, at the address
         of such holder shown on the records of the Company. With respect to
         certificates for Common Shares outstanding as of the Close of Business
         on the Record Date, until the Distribution Date, the Rights will be
         evidenced by such certificates registered in the names of the holders
         thereof together with a copy of the Summary of Rights. Until the
         Distribution Date (or the earlier of the Redemption Date, the Tender
         Offer Date, or the Final Expiration Date if occurring prior to the
         Distribution Date), the surrender for transfer of any certificate for
         Common Shares outstanding on the Record Date, with or without a copy of
         the Summary of Rights attached thereto, shall also constitute the
         transfer of the Rights associated with the Common Shares represented
         thereby.

                  (c) Certificates for Common Shares which become outstanding
         after the Record Date but prior to the earliest of the Distribution
         Date, the Redemption Date, the Tender Offer Date, or the Final
         Expiration Date shall have impressed on, printed on, written on or
         otherwise affixed to them the following legend:

                  This certificate also evidences and entitles the holder hereof
                  to certain rights as set forth in a Rights Agreement between
                  Rainforest Cafe, Inc. and Norwest Bank Minnesota, National
                  Association, dated as of May 23, 2000, as amended by Amendment
                  No. 1 to Rights Agreement dated as of September 26, 2000 (as
                  amended, the "RIGHTS AGREEMENT"), the terms of which are
                  hereby incorporated herein by reference and a copy of which is
                  on file at the principal executive offices of Rainforest Cafe,
                  Inc. Under certain circumstances, as set forth in the Rights
                  Agreement, such Rights will be evidenced by separate
                  certificates and will no longer be evidenced by this
                  certificate. Rainforest Cafe, Inc. will mail to the holder of
                  this certificate a copy of the Rights Agreement without charge
                  after receipt of a written request therefor. Under certain

<PAGE>   4

                  circumstances, as set forth in the Rights Agreement, Rights
                  issued to any Person who becomes an Acquiring Person or an
                  Associate or Affiliate thereof (as defined in the Rights
                  Agreement), or certain transferees of such Person, may become
                  null and void.

         With respect to such certificates containing the foregoing legend,
until the earlier of (i) the Distribution Date or (ii) the Final Expiration
Date, the Rights associated with the Common Shares represented by such
certificates shall be evidenced by such certificates alone, and the surrender
for transfer of any such certificate shall also constitute the transfer of the
Rights associated with the Common Shares represented thereby."

         Owner of the Threshold Percentage (or the Alternative Threshold
         Percentage, if applicable) or more of the then outstanding Common
         Shares as the result of acquisitions of Common Shares directly from the
         Company, provided, however, that if a Person shall become the
         Beneficial Owner of the Threshold Percentage (or the Alternative
         Threshold Percentage, if applicable) or more of the Common Shares of
         the Company then outstanding by reason of acquisitions of Common Shares
         directly from the Company and shall, after such share acquisitions from
         the Company, increase the number of Common Shares of the Company
         beneficially owned by such Person above the number of Common Shares of
         the Company beneficially owned by such Person at the time of the last
         such share acquisitions from the Company, then such Person shall be
         deemed to be an "Acquiring Person", and (vi) Landry's Seafood
         Restaurants, Inc., a Delaware corporation ("LANDRY'S"), together with
         all Affiliates (including, without limitation, LSR Acquisition Corp.)

         Distribution Date upon surrender of the Right Certificate, with the
         form of election to purchase on the reverse side thereof duly executed,
         to the Rights Agent at the office or offices of the Rights Agent
         designated for such purpose, together with payment of the Purchase
         Price for each one one-hundredth of a Preferred Share as to which the
