          provided,  however,  that a change in generally accepted accounting
          principles that results in an obligation of such Person that exists
          at such time becoming Debt shall not be deemed an Incurrence  of such
          Debt; provided further, however, that the  accretion of original
          issue discount on Debt shall not be deemed to be an Incurrence of
          Debt. Debt otherwise Incurred  by a Person before it becomes a

          (n) The sixth paragraph of Section 1010 of the Indenture is hereby
    amended to read in its entirety as follows:

          Person that is about to become  a Subsidiary of the Company as an
          Unrestricted Subsidiary, and may designate any newly-created
          Subsidiary as an Unrestricted Subsidiary, if at the time such
          Subsidiary is created it contains no assets (other than such de
          minimis amount of assets then required by law for the formation of
          corporations) and no Debt. Subsidiaries of the Company that are not

          Subsidiaries shall be deemed to be Restricted Subsidiaries.
          Notwithstanding any provisions of this Section 1010, all Subsidiaries
          of a Restricted Subsidiary shall be Restricted Subsidiaries and all
          Subsidiaries of an Unrestricted Subsidiary shall be Unrestricted
          Subsidiaries. The Board of Directors shall not change the designation
          of a Subsidiary of the Company more than twice in any period of five
          years."
