Officers' Certificate specifying the amount of Securities to be authenticated,

                  Section 2.2 Additional Definitions. Section 1.01 of the
     Indenture is hereby amended by adding the following definitions:

              "Additional Securities" means Series A Securities issued from time
              to time after the Issue Date under the terms of this Indenture
              (other than pursuant to Sections 2.06, 2.07, 2.10 or 3.06 of this
              Indenture).

                  Section 2.3. Amendment of Section 2.02. Section 2.02 of the
     Indenture is hereby amended by replacing it with the following:

              (a) Two Officers, or an Officer and a secretary, treasurer,
         controller or an assistant secretary of the Company, shall sign, or one
         Officer shall sign and one Officer or a Secretary or an Assistant
         Secretary of the Company (each of whom shall, in each case, have been
         duly authorized by all requisite corporate actions) shall attest to,
         the Securities for the Company by manual or facsimile signature.

              If an Officer or a secretary, treasurer, controller or an
         assistant secretary of the Company whose signature is on a Security was
         an Officer or a Secretary or an Assistant Secretary of the Company at
         the time of such execution but no longer holds that office at the time
         the Trustee authenticates the Security, the Security shall be valid
         nevertheless. Each Guarantor shall execute its Subsidiary Guarantee in
         the manner set forth in Section 10.07.

              A Security shall not be valid until an authorized signatory of the
         Trustee manually signs the certificate of authentication on the
         Security. The signature shall be conclusive evidence that the Security
         has been authenticated under this Indenture.

              (b) The Trustee shall authenticate (i) Securities for original
         issue on the Issue Date in the aggregate principal amount of
         $350,000,000, (ii) subject to compliance by the Company with clause (c)
         below, Additional Securities for original issue in an aggregate
         principal amount specified in a written order of the Company and (iii)
         Series B Securities for issue only in exchange, pursuant to the terms
         of a Registration Rights Agreement, for a like principal amount of
         Series A Securities, in each case upon a written order of the Company
         in the form of an Officers' Certificate. Each such Officers'
         Certificate shall specify the amount of Securities to be authenticated,
         the series of Securities and the date on which the Securities are to be
         authenticated.

              (c) Except as provided in Section 2.07, Additional Securities may
         be issued only in compliance with Section 4.03 and, in the case of any
         such Additional Securities, the Officers' Certificate specified in
         clause (b) above shall certify that (i) such issuance is not prohibited
         under Section 4.03 of this Indenture, and (ii) the principal amount of
         Securities secured by each Second Priority Mortgage then in effect will
         be equal to or greater than the principal amount of Securities
         outstanding after giving effect to such issuance. Any Additional
         Securities shall be part of the same issue as the Securities being
         issued on the Issue Date and will vote on all matters as one class with
         the Securities being issued on the

                                       4



         Issue Date, including, without limitation, waivers, amendments,
         redemptions, Change of Control Offers and Net Proceeds Offers.

              (d) Upon receipt of a written order of the Company in the form of
         an Officers' Certificate, the Trustee shall authenticate Securities in
         substitution for Securities originally issued to reflect any name
         change of the Company.

              (e) The Trustee may appoint an authenticating agent reasonably
         acceptable to the Company to authenticate Securities. Unless otherwise
         provided in the appointment, an authenticating agent may authenticate
         Securities whenever the Trustee may do so. Each reference in this
         Indenture to authentication by the Trustee includes authentication by
         such agent. An authenticating agent has the same rights as an Agent to
         deal with the Company and Affiliates of the Company.

              (f) The Securities shall be issuable only in registered form
         without coupons in denominations of $1,000 and any integral multiple
         thereof.

                                  ARTICLE III

                                   NOTE FORMS

              modified or supplemented from time to time, the "Indenture"),
              among the Company, the Guarantors and the Trustee."

     be issued to Holders of Additional Securities in exchange for their Series
     A Securities pursuant to the Exchange Offer specified in the Registration
     Rights Agreement shall be substantially in the form of Exhibit B to the
     Indenture, except that, for purposes of such Series B Securities, the first
     sentence of Section 4 of said Exhibit B shall be replaced with the
     following:

              "The Company issued the Securities under an Indenture, dated as of
