               2.   The   parties  agree   that   (a)  the   term
"Registrable  Securities" in  the Registration  Rights Agreement,
dated as of May 12, 1995,  by and among Parent, on the  one hand,
and RTZ and  RTZA, on  the other hand  (the "Parent  Registration
Rights Agreement"),  includes any  shares of Parent  Common Stock
acquired  by RTZ or its  Affiliates upon conversion  of any 6.55%
Notes,  however such 6.55% Notes are acquired, to the extent that
such shares of Parent Common Stock are not freely transferable by
RTZ or  its Affiliates without registration  under the Securities
Act and (b) the term "Registrable Securities" in the Registration
Rights  Agreement, dated as of May 12, 1995, between the Company,
on the  one hand, and RTZ,  RTZA and the Purchaser,  on the other
hand (the  "Company Registration Rights Agreement")  includes any
shares  of  Class  B Common  Stock  acquired  by  RTZ and/or  its
Affiliates in the  Spin-Off as  a result of  ownership of  Parent
Common Stock acquired by RTZ or its Affiliates upon conversion of
any 6.55% Notes, however such 6.55% Notes are acquired.

               3.   The first  sentence of Schedule 9.5.2  to the
Agreement  is hereby amended and restated to read in its entirety
as follows:

          "RTZA,  RTZ and  their Affiliates  will not  during the
          five-year period following the Spin-Off sell, exchange,

          conversion of  the 6.55%  Notes  or any  shares of  the
          Class  B Common  Stock  received in  the Spin-Off  with
          respect thereto  unless  they  first  obtain  either  a
          supplemental private  letter ruling from the  IRS or an
          opinion   of   nationally   recognized   tax   counsel,
          reasonably  satisfactory  to  Parent,  that  such sale,
          exchange,    transfer    or   other    disposition   (a
          "Disposition") will  not adversely affect  the tax-free
          nature of the Spin-Off or the ability of Parent to rely
          on  the Spin-Off  Private Letter  Ruling, in  each case
          other  than  with respect  to Section  367(e); provided
          that this restriction will not apply to the Disposition
          by RTZA,  RTZ and their Affiliates  following the Spin-

          manner described in  (iii) below), aggregate  less than
          1%  of the  number of  shares of  Company  Common Stock
          outstanding  immediately  following  the  Spin-Off,  or
          (iii)  shares of both  Parent Common Stock  and Class B
          Common Stock  where (x) such shares are  Disposed of in
          accordance with  a single plan of  disposition that has
          been communicated by RTZA, RTZ or their Affiliates to a
          sales agent, (y) the Disposition is completed within 60
          business days from the date of the first sale of Parent
          Common Stock or  Class B Common Stock pursuant  to such
          plan  and (z)  the shares  of Parent  Common  Stock and
          Class  B  Common  Stock  Disposed  of  represent  equal
          percentages of the respective  numbers of shares of the
          Parent Common  Stock and the Class B  Common Stock that
          RTZA, RTZ and their  Affiliates, in the aggregate, held
          immediately following the Spin-Off."
