                                    AGREEMENT

        NOW, THEREFORE, in consideration of the above recitals and for other
good and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto hereby agree as follows:


<PAGE>
        1. DEFINITIONS; INTERPRETATION. Unless otherwise indicated in this
Amendment, (a) each term set forth in Schedule 1.01 to the Participation
Agreement, when used in this Amendment, shall have the meaning given to that
term in such Schedule 1.01 and (b) the rules of interpretation set forth in
Schedule 1.02 to the Participation Agreement shall apply to this Amendment and
are incorporated herein by this reference.

        2. AMENDMENTS TO PARTICIPATION AGREEMENT. The Participation Agreement is
hereby amended as follows:

               (a) Schedule 1.01 is amended by adding thereto, in the
        appropriate alphabetical order, the following definition:

                      "Existing Subordinated Debt" shall mean (a) the
               Indebtedness of Lessee in the principal amount of $345,000,000
               outstanding under the 4.25% Convertible Subordinated Notes due
               March 15, 2004 issued by Lessee pursuant to the Indenture, dated
               as of March 15, 1999, between Lessee and State Street Bank and
               Trust Company of California, N.A., as Trustee, and (b) the
               Indebtedness of Lessee in the principal amount of $500,000,000
               outstanding under the Convertible Subordinated Notes due February
               15, 2005 issued by Lessee pursuant to the Subordinated Indenture,
               dated as of February 15, 2000, between Lessee and State Street
               Bank and Trust Company of California, N.A., as Trustee, in each
               case, in the form thereof in effect on the date of this
               Agreement.

               (b) Schedule 1.01 is further amended by changing the definition
        of "Subordinated Debt" to read in its entirety as follows:

                      "Subordinated Debt" shall mean:

                             (a)    The Existing Subordinated Debt; and

                             (b) Any other Indebtedness of Lessee or any of its
                      Subsidiaries the stated maturity date of any scheduled
                      principal payment of which is not earlier than the first
                      anniversary of the last Scheduled Expiration Date of any
                      Lease Supplement and which is subordinated on terms and
                      conditions reasonably acceptable to Required Participants;
                      provided, that any Subordinated Debt having subordination
                      provisions no more favorable in any material respect to
                      the holder than those attached as Exhibit I hereto shall
                      be deemed to be reasonably acceptable to Required
                      Participants for the purposes hereof.

               Without limiting the foregoing, the terms of such Subordinated
               Debt shall not include any requirement that the holders thereof
               approve the issuance of the Senior Debt or Designated Senior Debt
               (as defined in Exhibit I) entitled to the benefit of such
               subordination provisions.

        3. REPRESENTATIONS AND WARRANTIES. Lessee hereby represents and warrants
to Lessors, Lessor Agent, the Participants and Agent that the following are true
and correct on the





                                       2
<PAGE>

date of this Amendment and that, after giving effect to the amendments set forth
in Paragraph 2 above, the following will be true and correct on the date hereof:

                (a) The representations and warranties of Lessee set forth in
        Paragraph 4.01 of the Participation Agreement and in the other Operative
        Documents are true and correct in all material respects as if made on
        such date (except for representations and warranties expressly made as
        of a specified date, which shall be true in all material respects as of
        such date);

                (b) No Default has occurred and is continuing; and

                (c) All of the Operative Documents are in full force and effect.

(Without limiting the scope of the term "Operative Documents," Lessee expressly
acknowledges in making the representations and warranties set forth in this
Paragraph 3 that, on and after the date hereof, such term includes this
Amendment.)

        4. EFFECTIVENESS OF AMENDMENTS. The amendments set forth in Paragraph 2
above shall become effective upon receipt by Agent of this Amendment duly
executed by Lessee, Lessors, Lessor Agent, the Participants and Agent and, upon
such receipt, shall be deemed to amend the Participation Agreement from the
original date thereof as though incorporated in the Participation Agreement as
originally executed; subject, however, to the following:

                (a) It shall be a condition subsequent to the effectiveness of
        the amendments set forth in Paragraph 2 above that Lessee shall deliver
        to Agent, on or prior to September 30, 2001, the Conforming Amendment
        (as defined below). If Lessee fails so to deliver the Conforming
        Amendment, the amendments set forth in Paragraph 2 above shall cease to
        be effective, and be treated as though never adopted.

                (b) If the amendments set forth in Paragraph 2 above cease to be
        effective pursuant to Subparagraph 4(a) above, Lessee shall pay not
        later than October 15, 2001, as additional Base Rent under the Lease
        Agreement, such additional amount as Lessee would have been required to
        pay as Base Rent prior to September 30, 2001, had the Participation
        Agreement not been amended as provided in Paragraph 2 above. (The
        failure by Lessee to pay any such additional Base Rent during the period
        from the date of the Participation Agreement through September 30, 2001,
        will not constitute an Event of Default under the Lease Agreement,
        notwithstanding that the amendments set forth in Paragraph 2 above cease
        to be effective, and are treated as though never adopted pursuant to
        Subparagraph 4(a) above.)

As used herein, each term set forth below shall have the respective meaning
given to that term below:




                                       3
<PAGE>

               "BofA Participation Agreement" shall mean that certain
        Participation Agreement dated as of April 20, 2001 by and among Lessee,
        First Security Bank, National Association, not in its individual
        capacity except as expressly stated therein, but solely as certificate
        trustee and lessor, First Security Trust Company of Nevada, not in its
        individual capacity except as expressly stated therein, but solely as
        agent, the certificate purchasers party thereto, and the lenders party
        thereto.

               "Conforming Amendment" shall mean an amendment to the BofA
        Participation Agreement, substantially in the form attached hereto as
        Exhibit A, with such additional changes (if any) reasonably satisfactory
        to Agent (which approval shall not be unreasonably withheld) in order to
        cause the definition of "Subordinated Debt" in the BofA Participation
        Agreement to be substantially the same as the definition of
        "Subordinated Debt" in the Participation Agreement, as amended hereby
        (acknowledging, however, that each facility has its own expiration or
        termination date), and thereby to cause the definition of "Pricing
        Ratio" in the BofA Participation Agreement to be substantially the same
        as the definition of "Pricing Ratio" in the Participation Agreement, as
        amended hereby.

        5. EFFECT OF THIS AMENDMENT. During the period that the amendments set
forth in Paragraph 2 above are effective, each reference in the Participation
Agreement and the other Operative Documents to the Participation Agreement shall
mean the Participation Agreement as amended by this Amendment. Except as
expressly amended pursuant hereto, (a) the Participation Agreement and the other
Operative Documents shall remain unchanged and in full force and effect and are
hereby ratified and affirmed and (b) the execution, delivery and effectiveness
of this Amendment shall not, except as expressly provided herein, operate as a
waiver of any right, power, or remedy of Lessors, Lessor Agent, the Participants
or Agent, nor constitute a waiver of any provision of the Participation
Agreement or any other Operative Document.

        6.     MISCELLANEOUS.

               (a) Binding Effect. This Amendment shall be binding upon and
        inure to the benefit of Lessee, Lessors, the Participants, Lessor Agent,
        Agent and their respective permitted successors and assigns. All
        references in this Amendment to any Person shall be deemed to include
        all successors and assigns of such Person.

               (b) Counterparts. This Amendment may be executed in any number of
        identical counterparts, any set of which signed by all the parties
        hereto shall be deemed to constitute a complete, executed original for
        all purposes.

                            [Signature pages follow]
