      types described in subsections (a), (b), (c), (d), (e), (f) and (g) of
      this Section 2.01).

     SECTION 2.02.  Security for Obligations.  This Agreement secures the
payment and performance of all obligations of the Issuer and each other
Grantor, now or hereafter existing under the Service Provider Documents, the
MSAF Group Notes, the Secured Guarantee, the Secured Credit Facilities and the
Secured Swap Agreements, whether for principal, interest, fees, expenses or
otherwise (all such obligations of each Grantor being, collectively, the
"Secured Obligations").  Without limiting the generality of the foregoing, this
Agreement secures the payment of all amounts that constitute part of the
Secured Obligations and would be owed by any Grantor to the Secured Parties
under the Secured Obligations but for the fact that they are unenforceable or
not allowable due to the existence of a bankruptcy, reorganization or similar
proceeding involving such Grantor.

     SECTION 2.03.  Grantors Remain Liable.  Anything contained herein to the
contrary notwithstanding, (a) each Grantor shall remain liable under the
contracts and agreements included in the Collateral to the extent set forth
therein to perform all of its duties and obligations thereunder to the same
extent as if this Agreement had not been executed, (b) the exercise by the
Security Trustee of any of its rights hereunder shall not release any Grantor
from any of its duties or obligations under the contracts and agreements
included in the Collateral, and (c) no Secured Party shall have any obligation
or liability under the contracts and agreements included in the Collateral by
reason of this Agreement, nor shall any Secured Party be obligated to perform
any of the obligations or duties of any Grantor thereunder or to take any
action to collect or enforce any claim for payment assigned hereunder.

     SECTION 2.04.  Delivery of Collateral.  All certificates or instruments
representing or evidencing any Collateral shall be delivered to and held by or
on behalf of the Security Trustee pursuant hereto and shall be in suitable form
for transfer by delivery, or shall be accompanied by duly executed instruments
of transfer or assignment in blank, all in form and substance satisfactory to
the Security Trustee. The Security Trustee shall have the right, at any time in
its discretion and without notice to the Issuer, to transfer to or to register
in the name of the Security Trustee or any of its nominees any or all of the
Pledged Stock and Pledged Beneficial Interest, subject only to the revocable
rights specified in Section 2.10(a).  In addition, the Security Trustee shall
have the right at any time to exchange certificates or instruments representing
or evidencing any Collateral for certificates or instruments of smaller or
larger denominations.

     SECTION 2.05.  Maintenance of Accounts.  So long as any Secured
Obligations shall remain unpaid, the Security Trustee shall have sole dominion
and control over each Account other than any Non-Trustee Account, and no
Grantor shall, at any time, establish any bank account other than pursuant to
Article III of the Indenture, any Guarantor Indenture or in compliance with
Section 2.06(a).



   19





     SECTION 2.06.  Maintaining the Non-Trustee Accounts.  So long as any
Secured Obligations shall remain unpaid:

           (a) Each Grantor shall maintain each Non-Trustee Account in its name
      only with banks ("Non-Trustee Account Banks") that have entered into
      letter agreements in substantially the form of Exhibit D hereto (or made
      such other arrangements as are acceptable to the Administrative Agent)
      with such Grantor and the Security Trustee (the "Account Letters").

           (b) Each Grantor (i) shall immediately instruct each Person
      obligated at any time to make any payment to such Grantor for any reason
      (an "Obligor") to make such payment to an Account or a Non-Trustee
      Account meeting the requirements of Section 2.06(a), (ii) shall instruct
      each of its Non-Trustee Account Banks to transfer to the Collection
      Account, in immediately available funds, within one Business Day of
      receipt thereof, an amount equal to the credit balance of the Non-Trustee
      Account in such Non-Trustee Account Bank (other than any amount required
      to be left on deposit for local tax or other regulatory or legal
      purposes), and (iii) shall transfer or cause its Non-Trustee Account
      Banks to transfer to the Security Trustee for deposit in the Collection
      Account, within each Business Day, all other proceeds of Non-Trustee
      Account Collateral, Cash Collateral and proceeds of Collateral.

           (c) Upon any termination of any Account Letter or other agreement
      with respect to the maintenance of a Non-Trustee Account by any Grantor
      or any Non-Trustee Account Bank, such Grantor shall immediately notify
      all Obligors that were making payments to such Non-Trustee Account to
      make all future payments to an Account or to another Non-Trustee Account
      meeting the requirements of Section 2.06(a).  Subject to the terms of any
      Lease, upon request by the Security Trustee, each Grantor shall, and if
      prohibited from so doing by the terms of any Lease, shall use its best
      efforts to seek the consent of the relevant lessee to, terminate any or
      all of its Non-Trustee Accounts.

     SECTION 2.07.  Representations and Warranties of the Grantors.  Each
Grantor represents and warrants as of the date of this Agreement and as of each
subsequent Closing Date as follows:

           (a) Each Grantor is the legal and beneficial owner of the Collateral
      pledged and assigned by it hereunder free and clear of any Encumbrance,
      other than the security interest created by this Agreement.  No effective
      financing statement or other instrument similar in effect covering all or
      any part of the Collateral is on file in any recording office, except
      such as may have been filed in favor of the Security Trustee relating to
      this Agreement.

           (b) This Agreement, the pledge of the Security Collateral pursuant
      hereto and the pledge and assignment on the date hereof and from time to
      time hereafter of the other Collateral pursuant hereto create a valid and
      perfected security interest



   20




      therein, securing the payment of the Secured Obligations, subject in
      priority to no other claims, and all filings and other actions necessary
      or desirable to perfect and protect such security interest have been duly
      taken.

           (c) No Grantor has any trade names except as set forth on Schedule
      III hereto.

           (d) No consent of any other Person and no authorization, approval or
      other action by, and no notice to or filing with, any governmental
      authority or regulatory body or other third party is required either (i)
      for the grant by such Grantor of the assignment and security interest
      granted hereby, for the execution, delivery or performance of this
      Agreement by such Grantor or (ii) for the perfection or maintenance of
      the pledge, assignment and security interest created hereby, except for
      the filing of financing and continuation statements under the Uniform
      Commercial Code.

           (e) The chief place of business and chief executive or registered
      office of such Grantor and the office where such Grantor keeps records of
      each Assigned Lease to which it is a party are located at the address
      specified opposite the name of such Grantor on Schedule IV hereto.

           (f) The Pledged Stock constitutes the percentage of the issued and
      outstanding shares of stock of the issuers thereof indicated on Schedule
      I hereto.  The Pledged Beneficial Interest constitutes the percentage of
      the beneficial interest of the issuer thereof indicated on Schedule I
      hereto.

           (g) The Pledged Stock and the Pledged Beneficial Interest have been
      duly authorized and validly issued and are fully paid up and
      nonassessable.  The Pledged Debt has been duly authorized, authenticated
      or issued and delivered, is the legal, valid and binding obligation of
      each obligor thereunder and is not in default.

           (h) The Assigned Agreements and the Assigned Leases, true and
      complete copies of which have been furnished to the Security Trustee,
      have been duly authorized, executed and delivered by the relevant
      Grantors, have not been amended or otherwise modified, are in full force
      and effect and are binding upon and enforceable against all parties
      thereto in accordance with their terms.  There exists no default under
      any Assigned Agreement or any Assigned Lease by any Grantor party
      thereto.  Each party to any Assigned Agreements (there being none as of
      the date of this Agreement) other than the Issuer and the Security
      Trustee has executed and delivered to the Security Trustee a consent, in
      substantially the form of Exhibit E (or any other form approved in
      writing by the Administrative Agent), to the assignment of the relevant
      Agreement Collateral to the Security Trustee pursuant to this Agreement.
      Each party other than any Grantor to any Assigned Lease which by its
      terms requires the lessor thereof to obtain the consent of the lessee
      thereof, has executed and delivered to the Security Trustee a consent, in
      substantially the form of Exhibit E (or any other form approved in
      writing by the Administrative Agent), to the assignment of the relevant
      Lease Collateral to the



   21




      Security Trustee pursuant to this Agreement.  Each party to any other
      Assigned Lease other than any Grantor has been given due notice of the
      assignment of the relevant Lease Collateral to the Security Trustee
      pursuant to this Agreement.

     SECTION 2.08.  Further Assurances.  (a)  Each Grantor agrees that from
time to time, at the expense of such Grantor, such Grantor shall promptly
execute and deliver all further instruments and documents, and take all further
action, that may be necessary or desirable, or that the Security Trustee may
request, in order to perfect and protect any pledge, assignment or security
interest granted or purported to be granted hereby or to enable the Security
Trustee to exercise and enforce its rights and remedies hereunder with respect
to any Collateral. Without limiting the generality of the foregoing, each
Grantor shall:  (i) mark conspicuously each Assigned Agreement and Assigned
Lease to which it is a party and each of its records pertaining to the
Collateral with a legend, indicating that such Collateral is subject to the
security interest granted hereby; (ii) if any Collateral shall be evidenced by
a promissory note or other instrument or chattel paper, deliver and pledge to
the Security Trustee hereunder such note or instrument or chattel paper duly
indorsed and accompanied by duly executed instruments of transfer or
assignment; and (iii) execute and file such financing or continuation
statements, or amendments thereto, and such other instruments or notices, as
may be necessary or desirable, or as the Security Trustee may request, in order
to perfect and preserve the pledge, assignment and security interest granted or
purported to be granted hereby.

     (b) Each Grantor hereby authorizes the Security Trustee to file one or
more financing or continuation statements, and amendments thereto, relating to
all or any part of the Collateral without the signature of such Grantor where
permitted by law.  A photocopy or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.

     (c) Each Grantor shall furnish to the Security Trustee from time to time
statements and schedules further identifying and describing the Collateral and
such other reports in connection with the Collateral as the Security Trustee
may reasonably request, all in reasonable detail.

     (d) Each Grantor shall, immediately upon the organization or acquisition
by such Grantor of any Issuer Subsidiary or Guarantor Subsidiary, cause such
Issuer Subsidiary or Guarantor Subsidiary, as the case may be, to enter into a
Security Trust Agreement Supplement.

     SECTION 2.09.  Place of Perfection; Records.  Each Grantor shall keep its
chief place of business and chief executive office and the office where it
keeps its records concerning the Collateral at the location therefor specified
in Schedule IV or, upon 30 days' prior written notice to the Security Trustee,
at such other locations in a jurisdiction where all actions required by Section
2.07(e) shall have been taken with respect to the Collateral.  Each Grantor
shall hold and preserve such records and shall permit representatives of the
Security Trustee at any time during normal business hours to inspect and make
abstracts from such records, all at the sole cost and expense of such Grantor.




   22




     SECTION 2.10.  Voting Rights; Dividends; Etc. (a)  So long as no Default
Notice shall have been delivered to the Issuer or any Guarantor and no
Acceleration Default shall have occurred and be continuing:

           (i) Each of the Grantors shall be entitled to exercise any and all
      voting and other consensual rights pertaining to the Security Collateral
      and Beneficial Interest Collateral pledged by such Grantor or any part
      thereof for any purpose not inconsistent with the terms of this
      Agreement, the charter documents of such Grantor, the Indenture and any
      Guarantor Indenture; provided, however, that such Grantor shall not
      exercise or refrain from exercising any such right if in its judgment
      such action would have a material adverse effect on the value of the
      Security Collateral or the Beneficial Interest Collateral or any part
      thereof.

           (ii) The Security Trustee shall execute and deliver (or cause to be
      executed and delivered) to such Grantor all such proxies and other
      instruments as such Grantor may reasonably request for the purpose of
      enabling such Grantor to exercise the voting and other rights that it is
      entitled to exercise pursuant to Section 2.10(a)(i).

           (iii) Each Grantor shall be entitled to receive and retain any and
      all distributions, dividends and interest paid in respect of the Security
      Collateral and Beneficial Interest Collateral pledged by such Grantor;
      provided, however, that any and all

                 (A) distributions, dividends and interest paid or payable
            other than in cash in respect of, and instruments and other
            property received, receivable or otherwise distributed in respect
            of, or in exchange for, such Security Collateral or Beneficial
            Interest Collateral;

                 (B) distributions, dividends and other distributions paid or
            payable in cash in respect of such Security Collateral or
            Beneficial Interest Collateral in connection with a partial or
            total liquidation or dissolution or in connection with a reduction
            of capital, capital surplus or paid-in surplus; and

                 (C) cash paid, payable or otherwise distributed in respect of
            principal of, or in redemption of, or in exchange for, such
            Security Collateral or Beneficial Interest Collateral

      shall be, and shall be forthwith delivered to the Security Trustee to
      hold as, Security Collateral or Beneficial Interest Collateral, as the
      case may be, and, if received by such Grantor, shall be received in trust
      for the benefit of the Security Trustee, be segregated from the other
      property or funds of the Security Trustee and be forthwith delivered to
      the Security Trustee as Security Collateral or Beneficial Interest
      Collateral, as the case may be, in the same form as so received (with any
      necessary indorsement).




   23




     (b) Upon notice to such Grantor by the Security Trustee following the
delivery of a Default Notice to such Grantor or following the occurrence and
during the continuance of an Acceleration Default, all rights of such Grantor
(i) to exercise or refrain from exercising the voting and other consensual
rights that it would otherwise be entitled to exercise pursuant to Section
2.10(a)(i) and (ii) to receive the distributions, dividends and interest
payments that it would otherwise be entitled to receive and retain pursuant to
Section 2.10(a)(iii) shall cease, and all such rights shall thereupon become
vested in the Security Trustee, which shall thereupon have the sole right to
exercise or refrain from exercising such voting and other consensual rights.

     (c) All distributions, dividends and interest payments that are received
by such Grantor contrary to the provisions of Section 2.10(a) or (b) shall be
received in trust for the benefit of the Security Trustee, shall be segregated
from other funds of such Grantor and shall be forthwith paid over to the
Security Trustee as Security Collateral or Beneficial Interest Collateral, as
the case may be, in the same form as so received (with any necessary
indorsement).

     SECTION 2.11.  As to the Assigned Agreements and Assigned Leases.  (a)
Each Grantor shall at its expense:

           (i) perform and observe all the terms and provisions of the Assigned
      Agreements and Assigned Leases to be performed or observed by it,
      maintain the Assigned Agreements and Assigned Leases in full force and
      effect, enforce the Assigned Agreements and Assigned Leases in accordance
      with their terms and take all such action to such end as may be from time
      to time requested by the Security Trustee; and

           (ii) furnish to the Security Trustee promptly upon receipt thereof
      copies of all notices, requests and other documents received by such
      Grantor under or pursuant to the Assigned Agreements or Assigned Leases,
      and from time to time (A) furnish to the Security Trustee such
      information and reports regarding the Collateral as the Security Trustee
      may reasonably request and (B) upon request of the Security Trustee make
      to each other party to any Assigned Agreement or Assigned Lease such
      demands and requests for information and reports or for action as such
      Grantor is entitled to make thereunder.

     (b) No Grantor shall cancel or terminate any Assigned Agreement or consent
to or accept any cancellation or termination thereof or amend or otherwise
modify any Assigned Agreement.

     SECTION 2.12.  Transfers and Other Encumbrances; Additional Shares or
Interests.  (a)  No Grantor shall (i) sell, assign (by operation of law or
otherwise) or otherwise dispose of, or grant any option with respect to, any of
the Collateral or (ii) create or suffer to exist any Encumbrance upon or with
respect to any of the Collateral of such Grantor, other than the pledge,
assignment and security interest created by this Agreement.

shares, interests, participations or other equivalents.  Any beneficial
interest or stock or other securities or interests issued in respect of or in
substitution for the Pledged Stock or the Pledged Beneficial Interest shall be
issued to the Security Trustee.

     SECTION 2.13.  Security Trustee Appointed Attorney-in-Fact.  Each Grantor
hereby irrevocably appoints the Security Trustee such Grantor's
attorney-in-fact, with full authority in the place and stead of such Grantor
and in the name of such Grantor or otherwise, from time to time in the Security
Trustee's discretion, to take any action and to execute any instrument that the
Security Trustee may deem necessary or advisable to accomplish the purposes of
this Agreement, including, without limitation:

           (a) to ask for, demand, collect, sue for, recover, compromise,

      proceedings that the Security Trustee may deem necessary or desirable for
      the collection of any of the Collateral or otherwise to enforce the
      rights of the Security Trustee with respect to any of the Collateral; and

           (d) to execute and file any financing or continuation statements, or
      amendments thereto, and such other instruments or notices, as may be

     SECTION 2.14.  Security Trustee May Perform.  If any Grantor fails to
perform any agreement contained herein, the Security Trustee may (but shall not
be obligated to) itself perform, or cause performance of, such agreement, and
the expenses of the Security Trustee incurred in connection therewith shall be

     SECTION 2.15.  Covenant to Pay.  Each Grantor covenants with the Security
Trustee (for the benefit of the Security Trustee and the Secured Parties) that
it will pay or discharge any monies and liabilities whatsoever that are now, or
at any time hereafter may be, due, owing or payable by such Grantor in any
currency, actually or contingently, solely and/or jointly, and/or severally
with another or others, as principal or surety on any account whatsoever
pursuant to the Service Provider Documents, the Indenture, any Guarantor
Indenture, the MSAF Group Notes, the Secured Guarantee and the Secured Swap
Agreements in accordance with their terms.

     SECTION 2.16.  As to Permitted Account Investments.  (A) The Cash Manager,
acting on behalf of the Security Trustee, shall cause each Permitted Account
Investment made or acquired from or with the proceeds of any Non-Trustee
Account



   25




Collateral or Cash Collateral to be delivered to the Security Trustee as
follows (or shall take any and all other actions necessary to create in favor
of the Security Trustee a valid, perfected, first-priority security interest in
each Permitted Account Investment made or acquired in accordance with this
Agreement under laws and regulations (including without limitation Articles 8
and 9 of the UCC and regulations of the U.S. Department of the Treasury
governing transfers of interests in Government Securities) in effect at the
time of such making or acquisition):

           (i) in the case of each Certificated Security or Instrument, by (A)
      causing the delivery of such Certificated Security or Instrument to the
      Security Trustee in the State of New York, registered in the name of the
      Security Trustee or duly endorsed by an appropriate person to the
      Security Agent or in blank and, in each case, held by the Security
      Trustee in the State of New York, or (B) if such Certificated Security or
      Instrument is registered in the name of the Securities Intermediary on
      the books of the issuer thereof or on the books of any securities
      intermediary of the Securities Intermediary, by requesting the Securities
      Intermediary to continuously credit by book entry such Certificated
      Security or Instrument to the Securities Account and confirming that it
      has been credited;

           (ii) in the case of each Uncertificated Security, by (A) causing
      such Uncertificated Security to be continuously registered on the books
      of the issuer thereof in the name of the Security Trustee or (B) if such

      Securities Intermediary to continuously credit by book entry such
      Uncertificated Security to the Securities Account and confirming that it

      of New York or on the books of any securities intermediary of the
      Securities Intermediary, by requesting the Securities Intermediary to
      continuously credit by book entry such security to the Securities Account
      and confirming that it has been credited.

     (b) Each of the Issuer and Security Trustee hereby represents that it has
not entered into, and hereby agrees that it will not enter into, any agreement
(i) with any of the other parties hereto or any Securities Intermediary
specifying any jurisdiction other than the State of New York as the Securities
Intermediary's jurisdiction in connection with the Securities Account with the
Securities Intermediary referred to in Section 2.16(a) for purposes of 31

it will, by express agreement with the Securities Intermediary, provide for
each item of property held in the Securities Account, other than cash, to be
treated as a "financial asset" within the meaning of Section 8-102(a)(9) of the
UCC.




   26




     (c) Without limiting the foregoing, the Issuer and the Cash Manager on
behalf of the Security Trustee agree, and the Security Trustee shall cause the
Securities Intermediary, to take such different or additional action as the
Security Trustee may reasonably request in order to maintain the perfection and
priority of the security interest of the Security Trustee in the event of any
change in applicable law or regulation, including without limitation Articles 8
and 9 of the UCC and regulations of the U.S. Department of the Treasury
governing transfers of interests in Government Securities.

     SECTION 2.17.  As to Irish Law.  Notwithstanding anything to the contrary
contained in this Agreement and in addition to and without prejudice to any
other rights or power of the Security Trustee under this Agreement or under
general law in any relevant jurisdiction, at any time that the Collateral shall
become enforceable, the Security Trustee shall be entitled to appoint a
receiver under this Agreement or under the Conveyancing and Law of Property
Act, 1881 (as amended and as the same may be amended, modified or replaced from
time to time, the "1881 Act") and such receiver shall have all such powers,
rights and authority conferred under the 1881 Act, this Agreement and otherwise
under the laws of Ireland without any limitation or restriction imposed by the
1881 Act or otherwise under the laws of Ireland which may be excluded or
removed.  Sections 17 and 20 of the 1881 Act shall not apply to the Collateral
or any receiver appointed under this Agreement or under the 1881 Act and
section 24(b) of the Act shall not apply to the Collateral or to any receiver
appointed under this Agreement.


                              ARTICLE III

                                REMEDIES

     SECTION 3.01.  Remedies.  Upon delivery of a Default Notice pursuant to
Section 4.02 of the Indenture or any Guarantor Indenture or if any Acceleration
Default under the Indenture or any Guarantor Indenture shall have occurred and
be continuing:

           (a) The Security Trustee may exercise in respect of the Collateral,
      in addition to other rights and remedies provided for herein, all the
      rights and remedies of a secured party upon default under the UCC
      (whether or not the UCC applies to the affected Collateral) and also may
      (i) require any Grantor to, and such Grantor hereby agrees that it shall
      at its expense and upon request of the Security Trustee forthwith,
      assemble all or part of the Collateral as directed by the Security
      Trustee and make it available to the Security Trustee at a place to be
      designated by the Security Trustee that is reasonably convenient to both
      parties and (ii) without notice except as specified below, sell or cause
      the sale of the Collateral or any part thereof in one or more parcels at
      public or private sale, at any of the Security Trustee's offices or
      elsewhere, for cash, on credit or for future delivery, and upon such
      other terms as the Security Trustee may deem commercially reasonable.
      Each Grantor agrees that, to the extent notice of sale shall be required
      by law, at least ten days' notice to such Grantor of the time and place
      of any public sale or the time



   27




      after which any private sale is to be made shall constitute reasonable
      notification.  The Security Trustee shall not be obligated to make any
      sale of Collateral regardless of notice of sale having been given.  The
      Security Trustee may adjourn any public or private sale from time to time
      by announcement at the time and place fixed therefor, and such sale may,
      without further notice, be made at the time and place to which it was so
      adjourned.

           (b) All cash proceeds received by the Security Trustee in respect of
      any sale of, collection from, or other realization upon all or any part
      of the Collateral may, in the discretion of the Security Trustee, be held
      by the Security Trustee as collateral for, and/or then or at any time
      thereafter applied in whole or in part by the Security Trustee for the
      benefit of the Secured Parties against, all or any part of the Secured
      Obligations in accordance with Article VIII of this Agreement and Article
      III of the Indenture or any Guarantor Indenture.  Any surplus of such
      cash or cash proceeds held by the Security Trustee and remaining after
      payment in full of all the Secured Obligations shall be paid over to the
      relevant Grantors or whomsoever may be lawfully entitled to receive such
      surplus.  Any amount received for any sale or sales conducted in
      accordance with the terms of this Section 3.01 shall be deemed conclusive
      and binding on the Issuer, each Grantor and the Secured Parties.

      opinion of the Security Trustee, advisable to register such Security
      Collateral under the provisions of the Securities Act, to cause the
      registration statement relating thereto to become effective and to remain
      effective for such period as prospectuses are required by law to be
      furnished and to make all amendments and supplements thereto and to the
      related prospectus that, in the opinion of the Security Trustee, are

      Exchange Commission applicable thereto;

           (b) use its best efforts to qualify the Security Collateral under
      the state securities or "Blue Sky" laws and to obtain all necessary
      governmental approvals for the sale of the Security Collateral, as
      requested by the Security Trustee;

           (c) cause each issuer to make available to its security holders, as
      soon as



   28




      practicable, an earnings statement that shall satisfy the provisions of
      Section 11(a) of the Securities Act;

           (d) provide the Security Trustee with such other information and

      Trustee, advisable to enable the Security Trustee to effect the sale of
      such Security Collateral; and

           (e) do or cause to be done all such other acts and things as may be
      necessary to make such sale of the Security Collateral or any part
      thereof valid and binding and in compliance with applicable law.

The Security Trustee is authorized, in connection with any sale of the Security
Collateral pursuant to Section 3.01, to deliver or otherwise disclose to any
prospective purchaser of the Security Collateral (i) any registration statement
or prospectus, and all supplements and amendments thereto, prepared pursuant to
Section 4.01(a), (ii) any information and projections provided to it pursuant
to Section 4.01(d) and (iii) any other information in its possession relating
to the Security Collateral.


                               ARTICLE V

                       SECURITY INTEREST ABSOLUTE

     SECTION 5.01.  Security Interest Absolute.  The obligations of each
Grantor under this Agreement are independent of the Secured Obligations, and a
separate action or actions may be brought and prosecuted against such Grantor
to enforce this Agreement, irrespective of whether any action is brought
against any other Grantor or whether any other Grantor is joined in any such
action or actions.  All rights of the Security Trustee and the pledge,
assignment, and security interest hereunder, and all obligations of each
Grantor hereunder, shall be absolute and unconditional, irrespective of:

           (a) any lack of validity or enforceability of any Relevant Document,
      Service Provider Document, Secured Credit Facility, Secured Guarantee or
      Secured Swap Agreement or any other agreement or instrument relating
      thereto;

           (b) any change in the time, manner or place of payment of, the
      security for, or in any other term of, all or any of the Secured
      Obligations, or any other amendment or waiver of or any consent to any
      departure from any Relevant Document, Service Provider Document, Secured
      Credit Facility, Secured Guarantee or Secured Swap Agreement or any other
      agreement or instrument relating thereto;

           (c) any taking, exchange, release or non-perfection of the
      Collateral or any other collateral or taking, release or amendment or
      waiver of or consent to departure from any guaranty, for all or any of
      the Secured Obligations;

           (d) any manner of application of collateral, or proceeds thereof, to
      all or any of the Secured Obligations, or any manner of sale or other
      disposition of any collateral for all or any of the Secured Obligations
      or any other assets of the



   29




Grantors;

           (e) any change, restructuring or termination of the corporate
      structure or existence of any Grantor; or

           (f) any other circumstance that might otherwise constitute a defense
      available to, or a discharge of, any Grantor or a third-party grantor of
      a security interest.

action as trustee on behalf of the Secured Parties and to exercise such powers
and discretion under this Agreement and the other Relevant Documents as are

and no implied duties and covenants shall be deemed to arise hereunder against
the Security Trustee.

     (b) The Security Trustee accepts such appointment and agrees to perform
the same but only upon the terms of this Agreement and agrees to receive and
disburse all moneys received by it in accordance with the terms hereof.  The

Trustee shall not be liable for any action or inaction of any Grantor or any
other parties to any of the Relevant Documents.

     SECTION 6.02.  Absence of Duties.   The powers conferred on the Security

Trustee shall have no duty as to any Collateral, as to ascertaining or taking
action with respect to calls, conversions, exchanges, maturities, tenders or
other matters relative to any Collateral, whether or not any Secured Party has
or is deemed to have knowledge of such matters, or as to the taking of any
necessary steps to preserve or perfect rights against any parties or any other
rights pertaining to any Collateral.  The Security Trustee shall have no duty
to ascertain or inquire as to the performance or observance of any covenants,

   30




granted hereby, except that the Security Trustee in its individual capacity

document on its behalf, and (ii) this Agreement is the legal, valid and binding
obligation of Bankers Trust, enforceable against Bankers Trust in accordance

reorganization, moratorium or similar law affecting creditors' rights
generally.

     SECTION 6.04.  Reliance; Agents; Advice of Counsel.  (a)  The Security

signature, instrument, notice, resolution, request, consent, order,

be genuine and believed by it to be signed by the proper party or parties.  The
Security Trustee may accept a copy of a resolution of the Board of any party to
this Agreement or any Relevant Document, certified by the Secretary or an
Assistant Secretary thereof or other duly authorized Person of such party as
duly adopted and in full force and effect, as conclusive evidence that such
resolution has been duly adopted by said Board and that the same is in full
force and effect.  As to any fact or matter the manner of ascertainment of
which is not specifically described herein, the Security Trustee shall be
entitled to receive and may for all purposes hereof conclusively rely on a
certificate, signed by an officer of any duly authorized Person, as to such
fact or matter, and such certificate shall constitute full protection to the
Security Trustee for any action taken or omitted to be taken by it in good
faith in reliance thereon.  The Security Trustee shall furnish to each Service
Provider upon request such information and copies of such documents as the

perform its duties under the applicable Relevant Documents.  The Security
Trustee shall assume, and shall be fully protected in assuming, that each other
party hereto is authorized by its constitutional documents to enter into this
Agreement and to take all action permitted to be taken by it pursuant to the
provisions hereof, and shall not inquire into the authorization of such party
with respect thereto.

     (b) The Security Trustee may execute any of the powers hereunder or
perform any duties hereunder either directly or by or through agents, including
without limitation, financial advisors, or attorneys or a custodian or nominee,
and the Security Trustee shall not be responsible for any misconduct or
negligence on the part of, or for the supervision of, any such agent, attorney,
custodian or nominee appointed with due care by it hereunder.

     (c) The Security Trustee may consult with counsel and any opinion of
counsel or any advice of such counsel shall be full and complete authorization
and protection in respect of any action taken or suffered or omitted by it
hereunder in good faith and in accordance with such advice or opinion of
counsel.

     (d) The Security Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Agreement, or to institute, conduct
or defend any litigation hereunder or in relation hereto, at the request, order
or direction of any of the Secured Parties, pursuant to the provisions of this
Agreement, unless such Secured Party shall have offered to the Security Trustee
reasonable security or indemnity satisfactory to it



   31




against the costs, expenses and liabilities which may be incurred therein or
thereby.

     (e) The Security Trustee shall not be required to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if
there is reasonable ground for believing that the repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it, and none of the provisions contained in this Agreement shall in any event
require the Security Trustee to perform, or be responsible or liable for the
manner of performance of, any obligations of the Issuer or the Administrative
Agent under any of the Relevant Documents.

     (f) The Security Trustee shall not be liable for any Losses, Taxes or the
selection of Permitted Account Investments or for any investment losses

connection with an exercise of remedies specified in Section 3.01 or during a

expenses of its counsel) and the compensation for such services are intended to
constitute expenses of administration under any bankruptcy law or law relating
to creditors' rights generally.

     (h) The Security Trustee shall not be charged with knowledge of an Event
of Default unless a Responsible Officer of the Security Trustee obtains actual
knowledge of such event or the Security Trustee receives written notice of such
event from any of the Secured Parties or the Administrative Agent.

     (i) The Security Trustee shall have no duty to monitor the performance of
the Issuer, the Administrative Agent or any other party to the Relevant
Documents, nor shall it have any liability in connection with the malfeasance
or nonfeasance by such parties.  The Security Trustee shall have no liability
in connection with compliance by the Issuer, any Guarantor, the Administrative
Agent or any lessee under a Lease with statutory or regulatory requirements
related to the Collateral, any Aircraft or any Lease.  The Security Trustee
shall not make or be deemed to have made any representations or warranties with
respect to the Collateral, any Aircraft or any Lease or the validity or
sufficiency of any assignment or other disposition of the Collateral, any
Aircraft or any Lease.

     SECTION 6.05.  Not Acting in Individual Capacity.  The Security Trustee
acts hereunder solely as trustee unless otherwise expressly provided; and all
Persons having any claim against the Security Trustee by reason of the
transactions contemplated hereby shall look, subject to the lien and priorities

                           SUCCESSOR TRUSTEES



   32





     SECTION 7.01.  Resignation and Removal of Security Trustee.  The Security
Trustee may resign at any time without cause by giving at least 30 days' prior
written notice to the Issuer, any Guarantor and the Senior Representative.  The
Senior Representative may at any time remove the Security Trustee without cause
by an instrument in writing delivered to the Secured Parties and the Security
Trustee.  No termination of this Agreement by the Security Trustee or the
Senior Representative pursuant to this Section 7.01 shall become effective
prior to the date of appointment by the Senior Representative of a successor
Security Trustee and the acceptance of such appointment by such successor
Security Trustee.

     SECTION 7.02.  Appointment of Successor.  (a)  In the case of the
resignation or removal of the Security Trustee, the Senior Representative, on
behalf of the Secured Parties, shall promptly appoint a successor Security
Trustee.  If a successor Security Trustee shall not have been appointed and
accepted its appointment hereunder within 60 days after the Security Trustee
gives notice of resignation as to such class or subclass, the retiring Security
Trustee or the Secured Parties may petition any court of competent jurisdiction
for the appointment of a successor Security Trustee.  Any successor Security
Trustee so appointed by such court shall immediately and without further act be
superseded by any successor Security Trustee appointed as provided in the first
sentence of this paragraph within one year from the date of the appointment by
such court.

     (b) Any successor Security Trustee shall execute and deliver to the
Secured Parties an instrument accepting such appointment.  Upon the acceptance
of any appointment as Security Trustee hereunder a successor Security Trustee
and upon the execution and filing or recording of such financing statements, or
amendments thereto, and such amendments or supplements to this Agreement, and
such other instruments or notices, as may be necessary or desirable, or as the
Senior Trustee may request, in order to continue the perfection of the liens
granted or purported to be granted hereby, such Security Trustee shall succeed
to and become vested with all the rights, powers, discretion, privileges and
duties of the retiring Security Trustee, and the retiring Security Trustee
shall be discharged from its duties and obligations under this Agreement and
the other Relevant Documents.  After any retiring Security Trustee's
resignation or removal hereunder as to any actions taken or omitted to be taken
by it while it was Security Trustee, the provisions of all of Article VIII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Security Trustee under this Agreement.

     (c) Each Security Trustee shall be an Eligible Institution, if there be
such an institution willing, able and legally qualified to perform the duties
of a Security Trustee hereunder.

     (d) Any corporation into which the Security Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Security Trustee
shall be a party, or any corporation to which substantially all the business of
the Security Trustee may be transferred, shall be the Security Trustee under
this Agreement without further act.

                              ARTICLE VIII

                    AGREEMENT AMONG SECURED PARTIES

     SECTION 8.01.  Subordination and Priority.  (a)  Notwithstanding the date,
manner or order of attachment or perfection or the description of any
collateral or security interests, liens, claims or encumbrances covered or
granted by Section 2.01, each Subordinated Representative agrees that the
respective rights and interest of the Subordinated Creditors in the Collateral
are and shall be subordinate, to the extent and in the manner hereinafter set
forth, to all rights and interest of the Senior Creditors in the Collateral,
and that the Senior Creditors shall have at all times interests prior and
senior to that of the Subordinated Creditors in all Collateral until the
payment in full of all Senior Obligations owed to such Senior Creditors.

     (b) For the purposes of this Agreement, no Senior Obligations shall be
deemed to have been paid in full until and unless the Senior Representative in
respect of such Senior Obligations shall have received payment in full in cash
of such Senior Obligations.

     (c) Notwithstanding anything contained herein to the contrary, payments
from any property (or the proceeds thereof) deposited in the
Defeasance/Redemption Account pursuant to Article XI of the Indenture and any
Guarantor Indenture shall not be subordinated to the prior payment of any
Senior Creditors in respect of any Senior Obligations or subject to any other
restrictions set forth in this Article VIII, and none of the Holders shall be
obligated to pay over any payments from any such property to the Security
Trustee or any other creditor of any of the Grantors.

     SECTION 8.02.  Exercise of Remedies.  (a)  Until the date on which all the
Senior Obligations shall have been paid in full, the Senior Representative, in
its sole discretion and to the exclusion of the Subordinated Representatives,
shall have, whether or not any default under the Indenture or any Guarantor
Indenture shall have occurred and be continuing and both before and after the
commencement of any proceeding referred to in Section 8.03(a), the sole and
exclusive right (as between the Senior Representative, on the one hand, and the
Subordinated Representatives, on the other) to direct the Security Trustee to
take all action with respect to the Collateral, including, without limitation,
the right to exercise or direct voting or other consensual rights, to foreclose
or forebear from foreclosure in respect of the Collateral and to accept the
Collateral in full or partial satisfaction of any Senior Obligation, all in
accordance with the terms of this Agreement.  The Subordinated Representatives
agree that, until the Senior Obligations have been paid in full, the only right
of the Subordinated Creditors under this Agreement is for the Subordinated
Obligations to be secured by the Collateral for the period and to the extent
provided for herein and to receive a share of the proceeds of the Collateral,
if any.

     (b) The Subordinated Representatives agree that, so long as any of the
Senior Obligations shall remain unpaid, they and the Subordinated Creditors
will not commence, or join with any creditor other than the Security Trustee
and the Senior



   34




Creditors in commencing, any enforcement, collection, execution, levy or
foreclosure proceeding with respect to the Collateral or proceeds of
Collateral.  Upon request by the Senior Representative, the Subordinated
Representatives and the Subordinated Creditors will, at the expense of the
Issuer, join in enforcement, collection, execution, levy or foreclosure
proceedings and otherwise cooperate fully in the maintenance of such
proceedings by the Security Trustee, including without limitation by executing
and delivering all such consents, pleadings, releases and other documents and
instruments as the Security Trustee may reasonably request in connection
therewith, it being understood that the conduct of such proceedings shall at
all times be under the exclusive control of the Security Trustee.

     (c) The Subordinated Representatives agree, upon written request by the
Senior Representative, to release the liens and security interests in favor of
the Subordinated Creditors in any Collateral and to execute and deliver all
such directions, consents, pleadings, releases and other documents and
instruments as the Senior Representative may reasonably request in connection
therewith, upon any sale, lease, transfer or other disposition of such
Collateral or part thereof in accordance with, or for application of proceeds
pursuant to, Section 8.01(a).

     (d) The Subordinated Representatives agree that neither they nor any
Subordinated Creditors will contest, or bring (or join in) any action or
proceeding for the purpose of contesting, the validity, perfection or priority
of, or seeking to avoid, the rights of the Senior Representative or the Senior
Creditors in or with respect to the Collateral.

     SECTION 8.03.  Further Agreements of Subordination.  The Subordinated
Representatives agree as follows:

           (a) Upon any distribution of all or any of the Collateral or
      proceeds of Collateral to creditors of any Grantor upon the dissolution,
      winding-up, liquidation, arrangement, reorganization, adjustment,
      protection, relief, or composition of such Grantor or its debts, whether
      in any bankruptcy, insolvency, arrangement, reorganization, receivership,
      relief or similar proceedings or upon an assignment for the benefit of
      creditors or any other marshalling of the assets and liabilities of such
      Grantor, or otherwise, any distribution of any kind of Collateral or
      proceeds of Collateral that otherwise would be deliverable upon or with
      respect to the Subordinated Obligations shall be delivered directly to
      the Security Trustee for application (in the case of cash) to or as
      collateral (in the case of non-cash property or securities) for the
      payment or prepayment of the Senior Obligations until the Senior
      Obligations shall have been paid in full.

           (b) If any proceeding referred to in Section 8.03(a) is commenced by
      or against any Grantor,

                 (i) the Security Trustee is hereby irrevocably authorized and
            empowered (in its own name or in the name of the Secured Parties or
            otherwise), but shall have no obligation, to demand, sue for,
            collect and receive every distribution referred to in subsection
            (a) above and give



   35




            acquittance therefor and to file claims and proofs of claim and
            take such other action (including without limitation enforcing this
            Agreement) as it may deem necessary or advisable, or as the Senior
            Representative may direct, for the exercise or enforcement of any
            of the rights or interests of the Senior Creditors hereunder; and

                 (ii) the Subordinated Representatives shall duly and promptly
            take such action, at the expense of the Issuer, as the Senior
            Representative may request (A) to collect Collateral and proceeds
            of Collateral for the account of the Senior Creditors and to file
            appropriate claims or proofs of claim in respect of Collateral and
            proceeds of Collateral, (B) to execute and deliver to the Security
            Trustee such powers of attorney, assignments, or other instruments
            as the Senior Representative may request in order to enable it to
            enforce any and all claims with respect to the Collateral and
            proceeds of Collateral and (C) to collect and receive any and all
            payments or distributions that may be payable or deliverable upon
            or with respect to the Collateral or proceeds of Collateral.

           (c) All payments or distributions upon or with respect to the
      Collateral or proceeds of Collateral that are received by the
      Subordinated Representatives or the Subordinated Creditors contrary to
      the provisions of this Agreement shall be received for the benefit of the
      Senior Creditors, shall be segregated from other funds and property held
      by the Subordinated Representatives or the Subordinated Creditors and
      shall be forthwith paid over to the Security Trustee in the same form as
      so received (with any necessary indorsement) to be applied (in the case
      of cash) to or held as collateral (in the case of non-cash property or
      securities) for the payment or prepayment of the Senior Obligations in
      accordance with the terms thereof.

           (d) The Senior Representative is hereby authorized to demand
      specific performance of this Agreement at any time when any of the
      Subordinated Representatives or the Subordinated Creditors shall have
      failed to comply with any of the provisions of this Agreement applicable
      to them.  The Subordinated Representatives hereby irrevocably waive, on
      their own behalf and on behalf of the Subordinated Creditors, any defense
      based on the adequacy of a remedy at law that might be asserted as a bar
      to such remedy of specific performance.

     SECTION 8.04.  Possession of Collateral.  The Security Trustee agrees to
hold any Collateral received by it, in or against which a security interest or
lien may be perfected by possession, as bailee on behalf of the Secured
Parties.

     SECTION 8.05.  Rights of Subrogation.  The Subordinated Representatives
agree that no payment or distributions to the Senior Representative or the
Senior Creditors pursuant to the provisions of this Agreement shall entitle any
Subordinated Representative or any Subordinated Creditor to exercise any rights
of subrogation in respect thereof until all Obligations constituting Senior
Obligations with respect to such Person shall have been paid in full.



   36





     SECTION 8.06.  Further Assurances of Subordinated Representatives.  Each
of the Subordinated Representatives shall, at the expense of the Issuer, at any
time and from time to time promptly execute and deliver all further instruments
and documents, and take all further action, that the Senior Representative or
the Security Trustee may reasonably request, in order to protect any right or
interest granted or purported to be granted hereby or to enable the Senior
Representative and the Security Trustee to exercise and enforce their rights
and remedies hereunder.

     SECTION 8.07.  No Change in Rights in Collateral.  The Subordinated
Representatives and the Subordinated Creditors will not sell, assign, pledge,
encumber or otherwise dispose of any of their rights in the Collateral as such
or in proceeds of Collateral as such, without the prior written consent of the
Senior Representative.  Nothing in this Section 8.07 shall limit the right of
any Subordinated Creditor to transfer any Subordinated Obligation including,
without limitation, any Note.

     SECTION 8.08.  Waiver of Marshalling and Similar Rights.  Each of the
Subordinated Representatives waives, on its own behalf and on behalf of the
Subordinated Creditors, to the fullest extent permitted by applicable law, any
requirement regarding, and agrees not to demand, request, plead or otherwise
claim the benefit of, any marshalling, appraisement, valuation or other similar
right with respect to the Collateral that may otherwise be available under
applicable law or any other similar rights a junior creditor or junior secured
creditor may have under applicable law.

     SECTION 8.09.  Enforcement.  Each of the Subordinated Representatives
agrees that this Agreement shall be enforceable against it and the Subordinated
Creditors under all circumstances, including without limitation in any
proceeding referred to in Section 8.03(a).

     SECTION 8.10.  Obligations Hereunder Not Affected.  All rights and
interests of the Senior Representative, the Senior Creditors and the Security
Trustee hereunder, and all agreements and obligations of the Subordinated
Representatives under this Agreement, shall remain in full force and effect
irrespective of:

           (i) any lack of validity or enforceability of this Agreement, any
      Service Provider Document, MSAF Group Note, Secured Credit Facility,
      Secured Guarantee or Secured Swap Agreement or any other agreement or
      instrument relating thereto;

           (ii) any change in the time, manner or place of payment of, the
      security for, or in any other term of, all or any of the Senior
      Obligations, or any other amendment or waiver of or any consent to any
      departure from this Agreement, any Service Provider Document, MSAF Group
      Note, Secured Credit Facility, Secured Guarantee or Secured Swap
      Agreement or any other agreement or instrument relating thereto;

           (iii) any taking, exchange, release or non-perfection of the
      Collateral or any other collateral, or any release or amendment or waiver
      of or consent to



   37




departure from any guaranty, for all or any of the Senior Obligations; or

           (iv) any other circumstance that might otherwise constitute a
      defense available to, or a discharge of, the Subordinated
      Representatives, the Subordinated Creditors, a subordinated creditor or a
      secured subordinated creditor.

This Agreement shall continue to be effective or shall be revived or
reinstated, as the case may be, if at any time any payment of any of the Senior
Obligations is rescinded or must otherwise be returned by any Senior Creditor
upon the insolvency, bankruptcy or reorganization of any Grantor, or otherwise,
all as though such payment had not been made.

     SECTION 8.11.  Waiver.  The Subordinated Representatives hereby waive, on
their own behalf and on behalf of the Subordinated Creditors, to the fullest
extent permitted by law, any right under Section 9-504(1)(c) of the N.Y.
Uniform Commercial Code to application of the proceeds of disposition (other
than as contemplated by this Agreement), any right to notice and objection
under Section 9-505(2) of the N.Y. Uniform Commercial Code and promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Senior Obligations and this Agreement and any requirement that the Security
Trustee protect, secure, perfect or insure any security interest or lien
hereunder or otherwise or any Collateral or any other property subject thereto
or exhaust any right or take any action against the Grantors or any other
person or entity or any Collateral or any other collateral.

     SECTION 8.12.  Senior Obligations and Subordinated Obligations Unimpaired.
Nothing in this Agreement shall impair (i) as between the Issuer and any party
hereto, the obligations of the Issuer to such party, including without
limitation the Senior Obligations and the Subordinated Obligations, or (ii) as
between the Senior Creditors and the Subordinated Creditors, the provisions
relating to the priority of payments in the Indenture; provided that it is
understood that the enforcement of rights and remedies against the Collateral
shall be subject to the terms of this Agreement.

     SECTION 8.13.  Upon Discharge of Obligations.  Upon the payment in full of
the Senior Obligations in respect of which it is acting as Senior
Representative, the Security Trustee shall, without any further action on its

                               ARTICLE IX

                         INDEMNITY AND EXPENSES

     SECTION 9.01.  Indemnity.  (a)  The Issuer shall indemnify the Security
Trustee (and its officers, directors, employees and agents) for, and hold it
harmless against, any loss, liability or expense (including reasonable legal
fees and expenses) incurred by it without negligence or bad faith on its part
in connection with the acceptance or administration of this Agreement and its
duties hereunder, including the costs and expenses



   38




of defending itself against any claim or liability and of complying with any
process served upon it or any of its officers in connection with the exercise
or performance of any of its powers or duties and hold it harmless against, any
loss, liability or reasonable expense incurred without negligence or bad faith
on its part.  The Security Trustee shall notify the Issuer promptly of any
claim asserted against the Security Trustee for which it may seek indemnity;
provided, however, that failure to provide such notice shall not invalidate any
right to indemnity hereunder.  The Issuer shall defend the claim and the
Security Trustee shall cooperate in the defense.  The Security Trustee may have
separate counsel and the Issuer shall pay reasonable fees and expenses of such
counsel.  The Issuer need not pay for any settlements made without its consent;
provided that such consent shall not be unreasonably withheld.  The Issuer need
not reimburse any expense or indemnity against any loss or liability incurred
by the Security Trustee through negligence or bad faith.

     (b) The Issuer shall upon demand pay to the Security Trustee the amount of
any and all reasonable expenses, including the reasonable fees and expenses of
its counsel and of any experts and agents, that the Security Trustee may incur
in connection with (i) the administration of this Agreement, (ii) the custody,
preservation, use or operation of, or the sale of, collection from or other
realization upon, any of the Collateral, (iii) the exercise or enforcement of
any of the rights of the Security Trustee or any other Secured Party against
any Grantor hereunder or (iv) the failure by any Grantor to perform or observe
any of the provisions hereof.

     SECTION 9.02.  Noteholders' Indemnity.  The Security Trustee shall be
entitled, subject to such Security Trustee's duty during a default to act with
the required standard of care, to be indemnified by the Senior Creditors to the
sole satisfaction of the Security Trustee before proceeding to exercise any
right or power under this Agreement at the request or direction of the Senior
Representative.

     The provisions of Section 9.01 and Section 9.02 shall survive the
termination of this Agreement or the earlier resignation or removal of the
Security Trustee.

     SECTION 9.03.  No Compensation from Secured Parties.  The Security Trustee
agrees that it shall have no right against the Secured Parties for any fee as
compensation for its services hereunder.

     SECTION 9.04.  Security Trustee Fees.  In consideration of the Security
Trustee's performance of the services provided for under this Agreement, the
Issuer shall pay to the Security Trustee an annual fee set forth under a
separate agreement between the Issuer and the Security Trustee.


                               ARTICLE X

                             MISCELLANEOUS

     SECTION 10.01.  Amendments; Waivers; Etc.  (a)  No amendment or waiver of
any provision of this Agreement, and no consent to any departure by any party
herefrom, shall in any event be effective unless the same shall be in writing
and signed by



   39




each Service Provider, the Senior Trustee and, in the event it is adversely
affected thereby, the Subordinated Representative, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given.  No failure on the part of the Security Trustee to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other
right.  In executing and delivering any amendment or modification to this
Agreement, the Security Trustee shall be entitled to (i) an Opinion of Counsel
stating that such amendment is authorized and permitted pursuant to the
Indenture and this Agreement and complies therewith and herewith and (ii) an
Officer's Certificate stating that all conditions precedent to the execution,
delivery and performance of such amendment have been satisfied in full.  The
Security Trustee may, but shall have no obligation to, execute and deliver any
amendment or modification which would affect its duties, powers, rights,
immunities or indemnities hereunder.

     (b) Upon the execution and delivery by any Person of a security agreement
supplement in substantially the form of Exhibit C hereto, (i) such Person shall
be referred to as an "Additional Grantor" and shall be and become a Grantor
hereunder, and each reference in this Agreement to "Grantor" shall also mean
and be a reference to such Additional Grantor, (ii) the annexes attached to
each Security Trust Agreement Supplement shall be incorporated into and become
a part of and supplement Schedule III and Schedule IV, and the Security Trustee
may attach such annexes as supplements to such Schedules; and each reference to
such Schedules shall mean and be a reference to such Schedules as supplemented
pursuant hereto and (iii) such Additional Grantor shall be a Grantor for all
purposes under this Agreement and shall be bound by the obligations of the
Grantors hereunder.

     SECTION 10.02.  Addresses for Notices.  All notices and other

effective when deposited in the mails, telecopied, delivered to the telegraph
company, confirmed by telex answerback or delivered to the cable company,
respectively, addressed as aforesaid.

     SECTION 10.03.  No Waiver; Remedies.  No failure on the part of the
Security Trustee to exercise, and no delay in exercising, any right hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder preclude any other or further exercise thereof or the
exercise of any other right.  The remedies herein provided are cumulative and
not exclusive of any remedies provided by law.

     SECTION 10.04.  Severability.  If any provision of this Agreement shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions hereof shall not in any way be affected or impaired.

     SECTION 10.05.  Continuing Security Interest; Assignments.  Subject to the
Section 10.06(c), this Agreement shall create a continuing security interest in
the Collateral and shall (a) remain in full force and effect until the earlier
of the payment in full in cash of the Secured Obligations and the circumstances
specified in Section 10.06(c), (b) be binding upon each Grantor, its successors
and assigns and (c) inure, together with the rights and remedies of the
Security Trustee hereunder, to the benefit of the Secured Parties and their
respective successors, transferees and assigns.  Without limiting the
generality of the foregoing subsection (c), any Secured Party may assign or
otherwise transfer all or any portion of its rights and obligations under any
Relevant Document to which it is a party in accordance with the terms thereof
to any other Person or entity, and such other Person or entity shall thereupon
become vested with all the rights in respect thereof granted to such Secured
Party herein or otherwise.

     SECTION 10.06.  Release and Termination.  (a)  Upon any sale, lease,
transfer or other disposition of any item of Collateral in accordance with the
terms of the Indenture, the Security Trustee will, at the Issuer's expense,
execute and deliver to the Grantor of such item of Collateral such documents as
such Grantor shall reasonably request and provide to the Security Trustee to
evidence the release of such item of Collateral from the assignment and
security interest granted hereby.

     (b) Except as otherwise provided in Section 10.06(c), upon the payment in
full in cash of the Secured Obligations, the pledge, assignment and security
interest granted hereby shall terminate and all rights to the Collateral shall
revert to the Grantors.  Upon any such termination, the Security Trustee will,
at the Issuer's expense, execute and



   41




deliver to each relevant Grantor such documents as such Grantor shall prepare
and reasonably request to evidence such termination.

     (c) If at any time all Notes have been defeased pursuant to Article XI of
the Indenture, the pledge, assignment and security interest in the Pledged
Stock shall be released and the certificates representing the Pledged Stock
shall be returned to the Issuer and the Security Trustee shall, at the expense
of the Issuer, execute and deliver to the Issuer such documents as the Issuer
shall prepare and reasonably request to evidence such termination.

     SECTION 10.07.  Currency Conversion.  If any amount is received or
recovered by the Security Trustee in respect of this Agreement or any part
thereof in a currency (the "Received Currency") other than the currency in
which such amount was expressed to be payable (the "Agreed Currency"), then the
amount in the Received Currency actually received or recovered by the Security
Trustee, to the extent permitted by law, shall only constitute a discharge of
the relevant Grantor to the extent of the amount of the Agreed Currency which
the Security Trustee was or would have been able in accordance with its or his
normal procedures to purchase on the date of actual receipt or recovery (or, if
that is not practicable, on the next date on which it is so practicable), and,
if the amount of the Agreed Currency which the Security Trustee is or would
have been so able to purchase is less than the amount of the Agreed Currency
which was originally payable by the relevant Grantor, such Grantor shall pay to
the Security Trustee such amount as it shall determine to be necessary to
indemnify the Security Trustee against any Loss sustained by it as a result
(including the cost of making any such purchase and any premiums, commissions
or other charges paid or incurred in connection therewith) and so that, to the
extent permitted by law, (i) such indemnity shall constitute a separate and
independent obligation of each Grantor distinct from its obligation to
discharge the amount which was originally payable by such Grantor and (ii)
shall give rise to a separate and independent cause of action and apply
irrespective of any indulgence granted by the Security Trustee and continue in
full force and effect notwithstanding any judgment, order, claim or proof for a
liquidated amount in respect of the amount originally payable by any Grantor or
any judgment or order and no proof or evidence of any actual loss shall be
required.

     SECTION 10.08.  Governing Law.  THIS AGREEMENT SHALL IN ALL RESPECTS BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, EXCEPT TO THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY
INTERESTS HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
NEW YORK.  UNLESS OTHERWISE DEFINED HEREIN OR IN THE INDENTURES, TERMS USED IN
ARTICLE 9 OF THE UCC ARE USED HEREIN AS THEREIN DEFINED.

     SECTION 10.09.  Jurisdiction.  (a)  Each of the parties hereto irrevocably
agrees that the courts of New York shall have jurisdiction to hear and
determine any suit, action or proceeding, and to settle any disputes, which may
arise out of or in connection



   42




with this Agreement and, for such purposes, irrevocably submits to the
jurisdiction of such courts.  Each of the parties hereto irrevocably waives any
objection which it might now or hereafter have to the federal U.S. or New York
State courts located in New York, New York being nominated as the forum to hear
and determine any suit, action or proceeding, and to settle any disputes, which
may arise out of or in connection with this Agreement and agrees not to claim
that any such court is not a convenient or appropriate forum.  Each of the
parties hereto agrees that the process by which any suit, action or proceeding
is begun may be served on it by being delivered in connection with any suit,
action or proceeding in New York, New York to the Person named as the process
agent of such party in Exhibit F to the Indenture at the address set out
therein or at the principal New York City office of such process agent, if not
the same.

     (b) Each of the parties hereto hereby consents generally in respect of any
legal action or proceeding arising out of or in connection with this Agreement
to the giving of any relief or the issue of any process in connection with such
action or proceeding, including the making, enforcement or execution against
any property whatsoever (irrespective of its use or intended use) of any order
or judgment which may be made or given in such action or proceeding.

     SECTION 10.10.  Counterparts.  This Agreement may be executed in two or
more counterparts by the parties hereto, and each such counterpart shall be
considered an original and all such counterparts shall constitute one and the
same instrument.

     SECTION 10.11.  Table of Contents, Headings, Etc.  The Table of Contents
and headings of the Articles and Sections of this Agreement have been inserted
for convenience of reference only, are not to be considered a part hereof and
shall in no way modify or restrict any of the terms and provisions hereof.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered by its representative or officer thereunto duly
authorized as of the date first above written.

                         [Name of the Grantor]

Gentlemen/women:

     Reference is made to Account No. __________ into which certain monies,
instruments and other properties are deposited from time to time (the "Pledged

Pursuant to the Security Trust Agreement, dated as of March 3, 1998 (the
"Security Trust Agreement"), among the Grantor, Bankers Trust Company, as the
Administrative Agent (the "Administrative Agent"), various other parties and
Bankers Trust Company, not in its individual capacity (except as otherwise
provided pursuant to Sections 6.03(i) and 6.03(ii) of the Security Trust
Agreement), but solely as the initial Security Trustee (the "Security
Trustee").  Capitalized terms used herein, unless otherwise defined herein,
have the meanings assigned to them in the Security Trust Agreement.

     Pursuant to the Security Trust Agreement, the Grantor has granted to the
Security Trustee a security interest in certain property of the Grantor,
including, among other things, the following (the "Collateral"):  the Pledged
Account, all funds held or required by the terms of the Indenture or any
Guarantor Indenture to be held therein and all certificates and instruments, if
any, from time to time representing or evidencing such Pledged Account, all
notes, certificates of deposit, deposit accounts, checks and other instruments
from time to time hereafter delivered to or otherwise possessed by the Security
Trustee for or on behalf of such Grantor in substitution for or in addition to
any or all of the then existing Collateral, and all interest, dividends, cash,
instruments and other property from time to time received, receivable or
otherwise distributed in respect of or in exchange for any or all of the then
existing Collateral, and all proceeds of any and all of the foregoing
Collateral.  It is a condition to the continued maintenance of the Pledged

      relating to the Pledged Account, the Pledged Account is and will be

      Trustee or from an officer of the Administrative Agent.

           (b) You will follow your usual operating procedures for the handling
      of any remittance received in the Pledged Account, including any
      remittance that contains restrictive endorsements, irregularities (such

      postdated items, missing signatures, incorrect payees, etc.

           (c) You will transfer, in same day funds, on each of your business
      days, an amount equal to the credit balance of the Pledged Account (other

      "Collection Account"):

                     [Insert address of Operating Bank and
                   account number of the Collection Account]

      Each such transfer of funds shall neither comprise only part of a
      remittance nor reflect the rounding off of any funds so transferred.

           (d) All service charges and fees with respect to the Pledged Account
      shall be payable by the Grantor, and deposited checks returned for any
      reason shall not be charged to such account.

           (e) The Security Trustee and the Administrative Agent shall be
      entitled to exercise any and all rights of the Grantor in respect of the
      Pledged Account in accordance with the terms of the Security Trust
      Agreement, and the undersigned shall comply in all respects with such
      exercise.

     This letter agreement shall be binding upon you and your successors and
assigns and shall inure to the benefit of the Security Trustee, the Secured
Parties and their successors, transferees and assigns.  You may terminate this
letter agreement only upon 30 days' prior written notice to the Grantor and the
Security Trustee.  Upon such termination you shall close the Pledged Account
and transfer all funds in the Pledged Account to the Collection Account.  After
any such termination, you shall nonetheless remain obligated promptly to
transfer to the Collection Account all funds and other property received in
respect of the Pledged Account.

     This letter agreement shall be governed by and construed in accordance
with the laws of the State of New York.

                                        Very truly yours,
