ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  MCI has in effect an insurance policy covering officers' and directors'
legal liability containing a maximum limit of $50 million per loss per policy
year, including legal fees and expenses, with retained liability for each loss
of $2,000,000 for MCI.
 
  MCI's Restated Certificate of Incorporation, at Section 8, provides as
follows:
 
    (a) No director of this corporation shall be personally liable to this
  corporation or its stockholders for monetary damages for breach of
  fiduciary duty as a director; provided that this provision shall not
  eliminate or limit the liability of a director (i) for any breach of the
  director's duty of loyalty to this corporation or its stockholders, (ii)
  for acts or omissions not in good faith or which involve intentional
  misconduct or a knowing violation of law, (iii) under Section 174 of the
  General Corporation Law of the State of Delaware, or (iv) for any
  transaction from which the director derived an improper personal benefit.
  If the General Corporation Law of the State of Delaware is amended after
  approval by the stockholders of this paragraph (a) to authorize corporate
  action further limiting or eliminating the personal liability of directors,
  then the liability of a director of this Corporation shall be limited or
  eliminated to the fullest extent permitted by the General Corporation Law
  of the State of Delaware, as so amended. No amendment or repeal of this
  paragraph (a) shall apply to or have any effect on the liability or alleged
  liability of any director of this corporation for or with respect to any
  acts or omissions of such director occurring prior to such amendment or
  repeal.
 
    (b) This corporation shall, to the fullest extent permitted by Delaware
  law, as in effect from time to time, indemnify all persons who are or were
  directors, officers and employees of this corporation or any wholly-owned
  subsidiary, and all such directors, officers and employees who, at the
  request of this corporation, are or were at any time serving any other
  corporation, partnership, joint venture, trust, employee benefit plan or
  other enterprise in any capacity. This corporation may also indemnify all
  other persons to the fullest extent permitted by Delaware law.
 
  The General Corporation Law of the State of Delaware, at Section 145,
provides, in pertinent part, that a corporation may indemnify any person who
was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
the corporation), by reason of
 
                                     II-1
<PAGE>
 
the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as the
director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
if he acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere plea or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful. In addition, the indemnification of expenses (including
attorneys' fees) is allowed in derivative actions, except no indemnification
is allowed in respect to any claim, issue or matter as to which any such
person has been adjudged to be liable to the corporation, unless and only to
the extent that the Court of Chancery or the court in which such action or
suit was brought decides that indemnification is proper. To the extent that
any such person succeeds on the merits or otherwise, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith. The determination that the person to be
indemnified met the applicable standard of conduct, if not made by a court, is
made by the directors of the corporation by a majority vote of the directors
not party to such an action, suit or proceeding even though less than a quorum
or, if there are no such directors, or if such directors so direct, by
independent legal counsel in a written opinion or by the stockholders.
Expenses may be paid in advance upon the receipt of undertakings to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation as authorized in this section. A corporation
may purchase indemnity insurance.
 
  The above described indemnification and advancement of expenses, unless
otherwise provided when authorized or ratified, continue as to a person who
has ceased to be a director, officer, employee or agent and inure to the
benefit of such person's heirs, executors and administrators.
 
  MCI has indemnification agreements with each of its directors which have
been approved by stockholders. The indemnification under the indemnification
agreements differs from that provided in Section 8 of MCI's Certificate of
Incorporation in the following ways: (i) MCI is obligated to advance
litigation expenses to an indemnitee, subject to reimbursement if the
Reviewing Party (as defined in the indemnification agreements) determines that
the director would not be permitted such indemnification under applicable
laws; (ii) MCI must prove that the applicable standard of conduct has not been
met for indemnification if MCI denies protection to a director; (iii) upon a
potential change in control (as defined in the indemnification agreements) MCI
is required to contribute an amount sufficient to pay all claims for which the
indemnitee is entitled to be indemnified to a trust for the benefit of the
indemnitee (subject to an overall maximum amount on such trust); (iv) a
subsequent board of directors, hostile to an indemnitee entitled to
indemnification, will not have the right to make a final determination that
the indemnitee has not met the required standard of care; and (v) the period
of time in which MCI may sue an indemnitee for an action is limited to two
years from the date of accrual of such cause of action.
 
  Reference is made to the Underwriting Agreement Basic Provisions which is
filed as Exhibit 1.01 to this Registration Statement.
 
  Under the Trust Agreements, MCI will agree to indemnify each of the Trustees
of the Issuer or any predecessor Trustee for the Issuer, and to hold the
Trustees harmless against, any loss, damage, claims, liability or expense
incurred without negligence or bad faith on its part, arising out of or in
connection with the acceptance or administration of the Trust Agreements,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers
or duties under the Trust Agreements.
 
 
                                     II-2
<PAGE>
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers and controlling persons of the Registrants pursuant to the foregoing
provisions, or otherwise, the Registrants have been advised that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrants of expenses incurred or paid by a director, officer or
controlling person of the Registrants in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrants
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

Statement as of the time it was declared effective.
 
  (3) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the

fide offering thereof.
 
  (4) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

            (a)  On each Debenture Redemption Date and on the  stated
     maturity of the Debentures, the Trust will be required to redeem a Like
     Amount of Trust Securities at the Redemption Price.

                                      21


<PAGE>
 
            (b)  Notice of redemption shall be given by the Property Trustee
     by first-class mail, postage prepaid, mailed not less than 30 nor more than
     60 days prior to the Redemption Date to each Holder of Trust Securities to
     be redeemed, at such Holder's address appearing in the Security Register.
     All notices of redemption shall state:

                        (i)     the Redemption Date;

                       (ii)     the Redemption Price;

                      (iii)     the CUSIP number;

                       (iv)     if less than all the Outstanding Trust
            Securities are to be redeemed, the identification and the total
            Liquidation Amount of the particular Trust Securities to be
            redeemed; and

                        (v)     that on the Redemption Date the Redemption Price
            will become due and payable upon each such Trust Security to be
            redeemed and that distributions thereon will cease to accrue on and
            after said date.

            (c)  The Trust Securities redeemed on each Redemption Date shall
     be redeemed at the Redemption Price with the proceeds from the
     contemporaneous redemption of Debentures.  Redemptions of the Trust
     Securities shall be made and the Redemption Price shall be payable on each
     Redemption Date only to the extent that the Trust has funds then on hand
     and available in the Payment Account for the payment of such Redemption
     Price.

            (d)  If the Property Trustee gives a notice of redemption in
     respect of any Preferred Securities, then, by 12:00 noon, New York City
     time, on the Redemption Date, subject to Section 402(c), the Property
     Trustee will, so long as the Preferred Securities are in book-entry-only
     form, irrevocably deposit with the Clearing Agency for the Preferred
     Securities funds sufficient to pay the applicable Redemption Price and will
     give such Clearing Agency irrevocable instructions and authority to pay the
     Redemption Price to the holders thereof.  If the Preferred Securities are
     no longer in book-entry-only form, the Property Trustee, subject to Section
     402(c), will irrevocably deposit with the Paying Agent funds sufficient to
     pay the applicable Redemption Price and will give the Paying Agent
     irrevocable instructions and authority to pay the Redemption Price to the
     Holders thereof upon surrender of their Preferred Securities Certificates.
     Notwithstanding the foregoing, Distributions payable on or prior to the
     Redemption Date for 

                                      22


<PAGE>
 
     any Trust Securities called for redemption shall be payable to the Holders
     of such Trust Securities as they appear on the Register for the Trust
     Securities on the relevant record dates for the related Distribution Dates.
     If notice of redemption shall have been given and funds deposited as
     required, then upon the date of such deposit, all rights of Securityholders
     holding Trust Securities so called for redemption will cease, except the
     right of such Securityholders to receive the Redemption Price and any
     Distribution payable on or prior to the Redemption Date, but without
     interest, and such Securities will cease to be outstanding. In the event
     that any date on which any Redemption Price is payable is not a Business
     Day, then payment of the Redemption Price payable on such date will be made
     on the next succeeding day that is a Business Day (and without any interest
     or other payment in respect of any such delay), except that, if such
     Business Day falls in the next calendar year, such payment will be made on
     the immediately preceding Business Day, in each case, with the same force
     and effect as if made on such date. In the event that payment of the
     Redemption Price in respect of any Trust Securities called for redemption
     is improperly withheld or refused and not paid either by the Trust or by
     the Depositor pursuant to the Guarantee, Distributions on such Trust
     Securities will continue to accrue, at the then applicable rate, from the
     Redemption Date originally established by the Trust for such Trust
     Securities to the date such Redemption Price is actually paid, in which
     case the actual payment date will be the date fixed for redemption for
     purposes of calculating the Redemption Price.

            (e)  Payment of the Redemption Price on the Trust Securities
     shall be made to the recordholders thereof as they appear on the Securities
     Register for the Trust Securities on the relevant record date, which shall
     be one Business Day prior to the relevant Redemption Date; provided,
                                                                -------- 
     however, that in the event that the Preferred Securities do not remain in
     -------                                                                  
     book-entry-only form, the relevant record date shall be the date fifteen
     days prior to the relevant Redemption Date.

            (f)  Subject to Section 403(a), if less than all the Outstanding
     Trust Securities are to be redeemed on a Redemption Date, then the
     aggregate Liquidation Amount of Trust Securities to be redeemed shall be
     allocated on a pro rata basis (based on Liquidation Amounts) among the
     Common Securities and the Preferred Securities.  The particular Preferred
     Securities to be redeemed shall be selected on a pro rata basis (based upon
     Liquidation Amounts) not more than 60 days prior to the Redemption Date by
     the Property Trustee from the Outstanding Preferred Securities not

                                      23


<PAGE>
 
     previously called for redemption, by such method (including, without
     limitation, by lot) as the Property Trustee shall deem fair and appropriate
     and which may provide for the selection for redemption of portions (equal
     to $25 or an integral multiple of $25 in excess thereof) of the Liquidation
     Amount of Preferred Securities of a denomination larger than $25.  The
     Property Trustee shall promptly notify the Security Registrar in writing of
     the Preferred Securities selected for redemption and, in the case of any
     Preferred Securities selected for partial redemption, the Liquidation
     Amount thereof to be redeemed.  For all purposes of this Trust Agreement,
     unless the context otherwise requires, all provisions relating to the
     redemption of Preferred Securities shall relate, in the case of any
     Preferred Securities redeemed or to be redeemed only in part, to the
     portion of the Liquidation Amount of Preferred Securities that has been or
     is to be redeemed.

     SECTION 403.  Subordination of Common Securities
                   ----------------------------------

            (a)  Payment of Distributions (including Additional Amounts, if
     applicable) on, and the Redemption Price of, the Trust Securities, as
     applicable, shall be made, subject to Section 402(f), pro rata among the
     Common Securities and the Preferred Securities based on the Liquidation
     Amount of the Trust Securities; provided, however, that if on any
                                     --------  -------                
     Distribution Date or Redemption Date any Event of Default resulting from a
     Debenture Event of Default shall have occurred and be continuing, no
     payment of any Distribution (including Additional Amounts, if applicable)
     on, or Redemption Price of, any Common Security, and no other payment on
     account of the redemption, liquidation or other acquisition of Common
     Securities, shall be made unless payment in full in cash of all accumulated
     and unpaid Distributions (including Additional Amounts, if applicable) on
     all Outstanding Preferred Securities for all Distribution periods
     terminating on or prior thereto, or in the case of payment of the
     Redemption Price the full amount of such Redemption Price on all
     Outstanding Preferred Securities, shall have been made or provided for, and
     all funds immediately available to the Property Trustee shall first be
     applied to the payment in full in cash of all Distributions (including
     Additional Amounts, if applicable) on, or the Redemption Price of,
     Preferred Securities then due and payable.

            (b)  In the case of the occurrence of any Event of Default
     resulting from a Debenture Event of Default, the Holder of Common
     Securities will be deemed to have waived any right to act with respect to
     any such Event of Default under this Trust Agreement until the effect of
     all such 

                                      24


<PAGE>
 
     Events of Default with respect to the Preferred Securities have been cured,
     waived or otherwise eliminated. Until any such Event of Default under this
     Trust Agreement with respect to the Preferred Securities has been so cured,
     waived or otherwise eliminated, the Property Trustee shall act solely on
     behalf of the Holders of the Preferred Securities and not the Holder of the
     Common Securities, and only the Holders of the Preferred Securities will
     have the right to direct the Property Trustee to act on their behalf.

     SECTION 404.  Payment Procedures
                   ------------------

            Payments of Distributions (including Additional Amounts, if
  applicable) in respect of the Preferred Securities shall be made by check
  mailed to the address of the Person entitled thereto as such address shall
  appear on the Securities Register or, if the Preferred Securities are held by
  a Clearing Agency, such Distributions shall be made to the Clearing Agency in
  immediately available funds, which shall credit the relevant Persons' accounts
  at such Clearing Agency on the applicable distribution dates.  Payments in
  respect of the Common Securities shall be made in such manner as shall be
  mutually agreed between the Property Trustee and the Common Securityholder.

  SECTION 405.  Tax Returns and Reports
                -----------------------

            The Administrative Trustees shall prepare (or cause to be prepared),
  at the Depositor's expense, and file all United States federal, state and
  local tax and information returns and reports required to be filed by or in
  respect of the Trust.  In this regard, the Administrative Trustees shall (a)
  prepare and file (or cause to be prepared and filed) the appropriate Internal
  Revenue Service Form required to be filed in respect of the Trust in each
  taxable year of the Trust and (b) prepare and furnish (or cause to be prepared
  and furnished) to each Securityholder the appropriate Internal Revenue Service
  form required to be furnished to such Securityholder or the information
  required to be provided on such form.  The Administrative Trustees shall
  provide the Depositor and the Property Trustee with a copy of all such returns
  and reports promptly after such filing or furnishing.  The Trustees shall
  comply with United States federal withholding and backup withholding tax laws
  and information reporting requirements with respect to any payments to
  Securityholders under the Trust Securities.

  duties or governmental charges of whatsoever nature (other than withholding
  taxes) imposed on the Trust by the United States or any other taxing
  authority.

                 ------------------------

            Any amount payable hereunder to any Holder of Preferred Securities

  corresponding payment such Holder (and Owner) has directly received pursuant
  to Section 508 of the Indenture.

  Certificates bearing the manual signatures of individuals who were, at the

  this Trust Agreement, notwithstanding that such individuals or any of them
  shall have ceased to be so authorized prior to the delivery of such Trust
  Securities Certificates or did not hold such offices at the date of delivery
  of such Trust Securities Certificates.  A transferee of a Trust Securities
  Certificate shall become a Securityholder, and shall be entitled to the rights
  and subject to the obligations of a Securityholder hereunder, upon due
  registration of such Trust Securities Certificate in such transferee's name
  pursuant to Sections 504, 511 and 513.

  SECTION  504.  Registration of Transfer and Exchange of Preferred Securities
                 -------------------------------------------------------------
                  Certificates
                  ------------

            The Depositor shall keep or cause to be kept, at the office or
  agency maintained pursuant to Section 508, a register or registers for the
  purpose of registering Trust Securities Certificates and transfers and
  exchanges of Preferred Securities Certificates (the "Securities Register") in

  the registration of Preferred Securities Certificates and Common Securities
  Certificates (subject to Section 510 in the case of the Common Securities
  Certificates) and registration of transfers and exchanges of Preferred
  Securities Certificates as herein provided.  The Bank shall be the initial
  Securities Registrar.

            Upon surrender for registration of transfer of any Preferred
  Securities Certificate at the office or agency maintained pursuant to Section

  in the name of the designated transferee or transferees, one or more new
  Preferred Securities Certificates in authorized denominations of a like
  aggregate Liquidation Amount dated the date of execution by such
  Administrative Trustee or Trustees.  The Securities Registrar shall not be

  Certificates may be exchanged for other Preferred Securities Certificates in
  authorized denominations of the same class and of a like aggregate Liquidation
  Amount upon surrender of the Preferred Securities Certificates to be exchanged
  at the office or agency maintained pursuant to Section 508.

  registration of transfer or exchange shall be accompanied by a written
  instrument of transfer in form satisfactory to the Property Trustee and the
  Securities Registrar duly executed by the Holder or his attorney duly
  authorized in writing.  Each Preferred Securities Certificate surrendered for
  registration of transfer or exchange shall be cancelled and subsequently
  disposed of by the Property Trustee in accordance with its customary practice.

            No service charge shall be made for any registration of transfer or
  exchange of Preferred Securities Certificates, but the Securities Registrar
  may require payment of a sum sufficient to cover any tax or governmental
  charge that may be imposed in connection with any transfer or exchange of
  Preferred Securities Certificates.

  SECTION  505.  Mutilated, Destroyed, Lost or Stolen Trust Securities
                 -----------------------------------------------------
                 Certificates
                 ------------

         If (a) any mutilated Trust Securities Certificate shall be
  surrendered to the Securities Registrar, or if the Securities Registrar
  shall receive evidence to its satisfaction of the destruction, loss or
  theft of any Trust Securities Certificate and (b) there shall be delivered
  to the Securities Registrar and the Administrative Trustees such security
  or indemnity as may be required by them to save each of them harmless, then
  in the absence of notice that such Trust Securities Certificate shall have
  been acquired by a bona fide purchaser, the Administrative Trustees, or any
  one of them, on behalf of the Trust shall execute and make available for
  delivery, in exchange for or in lieu of any such mutilated, destroyed, lost
  or stolen Trust Securities Certificate, a new Trust Securities Certificate
  of like class, tenor and denomination.  In connection with the issuance of
  any new Trust Securities Certificate under this Section, the Administrative
  Trustees or the Securities Registrar may require the payment of a sum
  sufficient to cover any tax or other governmental charge that may be
  imposed in connection therewith.  Any duplicate Trust Securities
  Certificate issued pursuant to this Section shall constitute conclusive
  evidence of an undivided beneficial interest in the assets of the Trust, as
  if originally issued, whether or not the lost, stolen or destroyed Trust
  Securities Certificate shall be found at any time.

  SECTION 506.    Persons Deemed Securityholders
                  ------------------------------

            The Administrative Trustees or the Securities Registrar shall treat
  the Person in whose name any Trust Securities Certificate shall be registered
  in the Securities Register as the owner of such Trust Securities Certificate
  for the purpose of receiving distributions and for all other purposes
  whatsoever, and neither the Trustees nor the Securities Registrar shall be
  bound by any notice to the contrary.

  SECTION 507.    Access to List of Securityholders' Names and Addresses
                  ------------------------------------------------------

            The Administrative Trustees or the Depositor shall furnish or cause
  to be furnished (a) to the Property Trustee, semi-annually on or before
  January 15 and July 15 in each year, a list, in such form as the Property
  Trustee may reasonably require, of the names and addresses of the
  Securityholders as of the most recent Record Date and (b) to the Property
  Trustee, promptly after receipt by any Administrative Trustee or the Depositor
  of a request therefor from the Property Trustee in order to enable the
  Property Trustee to discharge its obligations under this Trust Agreement, in
  each case to the extent such information is in the possession or control of
  the Administrative Trustees or the Depositor and is not identical to a
  previously supplied list or has not otherwise been received by the Property
  Trustee in its capacity as Securities Registrar.  The rights of
  Securityholders to communicate with other Securityholders with respect to
  their rights under this Trust Agreement or under the Trust Securities, and the
  corresponding rights of the Trustee shall be as provided in the Trust
  Indenture Act.  Each Holder, by receiving and holding a Trust Securities
  Certificate, and each Owner shall be deemed to have agreed not to hold the
  Depositor, the Property Trustee or the Administrative Trustees accountable by
  reason of the disclosure of its name and address, regardless of the source
  from which such information was derived.

  SECTION 508.    Maintenance of Office or Agency
                  -------------------------------

            The Administrative Trustees shall maintain an office or offices or
  agency or agencies where Preferred Securities Certificates may be surrendered
  for registration of transfer or exchange and where notices and demands to or
  upon the Trustees in respect of the Trust Securities Certificates may be
  served.  The Administrative Trustees initially designate MCI Communications
  Corporation, 1801 Pennsylvania Avenue, N.W., Washington, D.C. 20006,
  Attention: Treasurer, as the office for such purposes. The

                                      29 


<PAGE>
 
  Administrative Trustees shall give prompt written notice to the Depositor and
  to the Securityholders of any change in the location of the Securities
  Register or any such office or agency.

  SECTION 509.    Appointment of Paying Agent.
                  ---------------------------

            The Paying Agent shall make distributions to Securityholders from
  the Payment Account and shall report the amounts of such distributions to the
  Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
  the revocable power to withdraw funds from the Payment Account for the purpose
  of making the distributions referred to above.  The Administrative Trustees
  may revoke such power and remove the Paying Agent if such Trustees determine
  in their sole discretion that the Paying Agent shall have failed to perform
  its obligations under this Trust Agreement in any material respect.  The
  Paying Agent shall initially be the Bank, and any co-paying agent chosen by
  the Bank and acceptable to the Administrative Trustees and the Depositor.  Any
  Person acting as Paying Agent shall be permitted to resign as Paying Agent
  upon 30 days' written notice to the Administrative Trustees, the Property
  Trustee and the Depositor.  In the event that the Bank shall no longer be the
  Paying Agent or a successor Paying Agent shall resign or its authority to act
  be revoked, the Administrative Trustees shall appoint a successor that is
  acceptable to the Property Trustee and the Depositor to act as Paying Agent
  (which shall be a bank or trust company).  The Administrative Trustees shall
  cause such successor Paying Agent or any additional Paying Agent appointed by
  the Administrative Trustees to execute and deliver to the Trustees an
  instrument in which such successor Paying Agent or additional Paying Agent
  shall agree with the Trustees that as Paying Agent, such successor Paying
  Agent or additional Paying Agent will hold all sums, if any, held by it for
  payment to the Securityholders in trust for the benefit of the Securityholders
  entitled thereto until such sums shall be paid to such Securityholders.  The
  Paying Agent shall return all unclaimed funds to the Property Trustee and upon
  removal of a Paying Agent such Paying Agent shall also return all funds in its
  possession to the Property Trustee.  The provisions of Sections 801, 803 and
  806 shall apply to the Bank also in its role as Paying Agent, for so long as
  the Bank shall act as Paying Agent and, to the extent applicable, to any other
  paying agent appointed hereunder.  Any reference in this Agreement to the
  Paying Agent shall include any co-paying agent unless the context requires
  otherwise.

  SECTION 510.  Ownership of Common Securities by Depositor.
                ------------------------------------------- 

            At each Time of Delivery, the Depositor shall acquire and retain
  beneficial and record ownership of the Common Securities.  To the fullest
  extent permitted by law, other than a transfer in connection with a
  consolidation or merger of the Depositor into another corporation, or any
  conveyance, transfer or lease by the Depositor of its properties and assets
  substantially as an entirety to any Person, pursuant to Section 801 of the
  Indenture, any attempted transfer of the Common Securities shall be void.  The
  Administrative Trustees shall cause each Common Securities Certificate issued
  to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
  TRANSFERABLE".

            (a)  The Preferred Securities Certificates, upon original
     issuance, will be issued in the form of a typewritten Preferred Securities
     Certificate or Certificates representing Book-Entry Preferred Securities
     Certificates, to be delivered to The Depository Trust Company, the initial
     Clearing Agency, by, or on behalf of, the Trust.  Such Preferred Securities
     Certificate or Certificates shall initially be registered on the Securities
     Register in the name of Cede & Co., the nominee of the initial Clearing
     Agency, and no beneficial owner will receive a Definitive Preferred
     Securities Certificate representing such beneficial owner's interest in
     such Preferred Securities, except as provided in Section 513.  Unless and
     until Definitive Preferred Securities Certificates have been issued to
     beneficial owners pursuant to Section 513:

              (i)  the provisions of this Section 511(a) shall be in full
       force and effect;

             (ii)  the Securities Registrar and the Trustees shall be
       entitled to deal with the Clearing Agency for all purposes of this Trust
       Agreement relating to the Book-Entry Preferred Securities Certificates
       (including the payment of the Liquidation Amount of and Distributions on
       the Book-Entry Preferred Securities and the giving of instructions or
       directions to Owners of Book-Entry Preferred Securities) as the sole
       Holder of Book-Entry Preferred Securities and shall have no obligations
       to the Owners thereof;

            (iii)  to the extent that the provisions of this Section 511
       conflict with any other provisions of this

                                      31

       Trust Agreement, the provisions of this Section 511 shall control; and

             (iv)  the rights of the Owners of the Book-Entry Preferred
       Securities Certificates shall be exercised only through the Clearing
       Agency and shall be limited to those established by law and agreements
       between such Owners and the Clearing Agency and/or the Clearing Agency
       Participants.  Pursuant to the Certificate Depository Agreement, unless
       and until Definitive Preferred Securities Certificates are issued
       pursuant to Section 513, the initial Clearing Agency will make book-entry
       transfers among the Clearing Agency Participants and receive and transmit
       payments on the Preferred Securities to such Clearing Agency
       Participants.

            (b)  A single Common Securities Certificate representing the
     Common Securities shall be issued to the Depositor in the form of a
     definitive Common Securities Certificate.

  SECTION 512.  Notices to Clearing Agency.
                -------------------------- 

            To the extent that a notice or other communication to the Owners is
  required under this Trust Agreement, unless and until Definitive Preferred
  Securities Certificates shall have been issued to Owners pursuant to Section
  513, the Trustees shall give all such notices and communications specified
  herein to be given to Owners to the Clearing Agency, and shall have no
  obligations to the Owners.

  SECTION 513.  Definitive Preferred Securities Certificates.
                -------------------------------------------- 

            If (a) the Depositor advises the Trustees in writing that the
  Clearing Agency is no longer willing or able to properly discharge its
  responsibilities with respect to the Preferred Securities Certificates, and
  the Depositor is unable to locate a qualified successor, (b) the Depositor at
  its option advises the Trustees in writing that it elects to terminate the
  book-entry system through the Clearing Agency, or (c) after the occurrence of
  a Debenture Event of Default, Owners of Preferred Securities Certificates
  representing beneficial interests aggregating at least a majority of the
  Liquidation Amount advise the Property Trustee in writing that the
  continuation of a book-entry system through the Clearing Agency is no longer
  in the best interest of the Owners of Preferred Securities Certificates, then
  the Property Trustee shall notify the Clearing Agency and the Clearing Agency
  shall notify all Owners of Preferred Securities Certificates and the other
  Trustees of the 

                                      32

                                      
<PAGE>
 
  occurrence of any such event and of the availability of the Definitive
  Preferred Securities Certificates to Owners of such class or classes, as
  applicable, requesting the same. Upon surrender to the Property Trustee of the
  typewritten Preferred Securities Certificate or Certificates representing the
  Book-Entry Preferred Securities Certificates by the Clearing Agency,
  accompanied by registration instructions, the Administrative Trustees, or any
  one of them, shall execute the Definitive Preferred Securities Certificates in
  accordance with the instructions of the Clearing Agency. Neither the
  Securities Registrar nor the Trustees shall be liable for any delay in
  delivery of such instructions and may conclusively rely on, and shall be
  protected in relying on, such instructions. Upon the issuance of Definitive
  Preferred Securities Certificates, the Trustees shall recognize the Holders of
  the Definitive Preferred Securities Certificates as Securityholders. The
  Definitive Preferred Securities Certificates shall be printed, lithographed or
  engraved or may be produced in any other manner as is reasonably acceptable to
  the Administrative Trustees, as evidenced by the execution thereof by the
  Administrative Trustees or any one of them.

  SECTION 514.  Rights of Securityholders.
                ------------------------- 

            (a)  The legal title to the Trust Property is vested exclusively in
  the Property Trustee (in its capacity as such) in accordance with Section 209,
  and the Securityholders shall not have any right or title therein other than
  the undivided beneficial interest in the assets of the Trust conferred by
  their Trust Securities and they shall have no right to call for any partition
  or division of property, profits or rights of the Trust except as described
  below.  The Trust Securities shall be personal property giving only the rights
  specifically set forth therein and in this Trust Agreement.  The Trust
  Securities shall have no preemptive or similar rights and when issued and
  delivered to Securityholders against payment of the purchase price therefor
  will be fully paid and nonassessable by the Trust.  The Holders of the Trust
  Securities, in their capacities as such, shall be entitled to the same
  limitation of personal liability extended to stockholders of private
  corporations for profit organized under the General Corporation Law of the
  State of Delaware.

            (b)  For so long as any Preferred Securities remain Outstanding, if,
  upon a Debenture Event of Default, the Debenture Trustee fails or the holders
  of not less than 25% in principal amount of the outstanding Debentures fail to
  declare the principal of all of the Debentures to be immediately due and
  payable, the Holders of at least 25% in

                                      33 


<PAGE>
 
  Liquidation Amount of the Preferred Securities then Outstanding shall have
  such right by a notice in writing to the Depositor and the Debenture Trustee;
  and upon any such declaration such principal amount of and the accrued
  interest on all of the Debentures shall become immediately due and payable,
  provided that the payment of principal and interest on such Debentures shall
  remain subordinated to the extent provided in the Indenture.

            (c)  For so long as any Preferred Securities remain Outstanding, to
  the fullest extent permitted by law and subject to the terms of this Trust
  Agreement, if, upon a Debenture Event of Default specified in Section 501(1)
  or 501(2) of the Indenture, any Holder of Preferred Securities shall have the
  right to directly institute a proceeding for enforcement of payment to such
  Holder of the principal amount of or interest on the Debentures having a
  principal amount equal to the Liquidation Amount of the Preferred Securities
  of such Holder (a "Direct Action").  In connection with such Direct Action,
  the rights of the Holders of the Common Securities will be subrogated to the
  rights of any Holder of the Preferred Securities to the extent of any payment
  made by the Depositor to such Holder of Preferred Securities in such Direct
  Action.  Except as set forth in this Section 514(c), the Holders of Preferred
  Securities will not be able to exercise directly any other remedy available to
  the holders of the Debentures or assert directly any other rights in respect
  of the Debentures.

                                  ARTICLE VI
                                  -----------
                   Acts of Securityholders; Meetings; Voting
                   -----------------------------------------

  SECTION 601.   Limitations on Voting Rights
                 ----------------------------

            (a)  Except as provided in this Section, in Sections 810 and
     1002 and in the Indenture and as otherwise required by law, no Holder of
     Preferred Securities shall have any right to vote or in any manner
     otherwise control the administration, operation and management of the Trust
     or the obligations of the parties hereto, nor shall anything herein set
     forth, or contained in the terms of the Trust Securities Certificates, be
     construed so as to constitute the Securityholders from time to time as
     partners or members of an association.

            (b)  So long as any Debentures are held by the Property Trustee,
     the Trustees shall not (i) direct the time, method and place of conducting
     any proceeding for any remedy available to the Debenture Trustee, or
     executing any trust or power conferred on the Debenture Trustee with
     respect to such Debentures, (ii) waive any past default

                                      34 


<PAGE>
 
     which is waiveable under Section 513 of the Indenture, (iii) exercise any
     right to rescind or annul a declaration that the principal of all the
     Debentures shall be due and payable or (iv) consent to any amendment,
     modification or termination of the Indenture or the Debentures, where such
     consent shall be required, without, in each case, obtaining the prior
     approval of the Holders of at least a majority in Liquidation Amount of all
     Outstanding Preferred Securities; provided, however, that where a consent
                                       --------  -------  
     under the Indenture would require the consent of each Holder of Debentures
     affected thereby, no such consent shall be given by the Property Trustee
     without the prior written consent of each Holder of Preferred Securities.
     The Trustees shall not revoke any action previously authorized or approved
     by a vote of the Holders of Preferred Securities, except by a subsequent
     vote of the Holders of Preferred Securities. The Property Trustee shall
     notify all Holders of the Preferred Securities of any notice of default
     received from the Debenture Trustee with respect to the Debentures. In
     addition to obtaining the foregoing approvals of the Holders of the
     Preferred Securities, prior to taking any of the foregoing actions, the
     Trustees shall, at the expense of the Depositor, obtain an Opinion of
     Counsel experienced in such matters to the effect that the Trust will not
     be classified as an association taxable as a corporation for United States
     federal income tax purposes on account of such action.

            (c)  If any proposed amendment to the Trust Agreement provides
     for, or the Trustees otherwise propose to effect, (i) any action that would
     adversely affect in any material respect the powers, preferences or special
     rights of the Preferred Securities, whether by way of amendment to the
     Trust Agreement or otherwise, or (ii) the dissolution, winding-up or
     termination of the Trust, other than pursuant to the terms of this Trust
     Agreement, then the Holders of Outstanding Preferred Securities as a class
     will be entitled to vote on such amendment or proposal and such amendment
     or proposal shall not be effective except with the approval of the Holders
     of at least a majority in Liquidation Amount of the Outstanding Preferred
     Securities.  No amendment to this Trust Agreement may be made if, as a
     result of such amendment, the Trust would be classified as an association
     taxable as a corporation for United States federal income tax purposes.

  SECTION 602.   Notice of Meetings.
                 ------------------

            Notice of all meetings of the Preferred Securityholders, stating the
  time, place and purpose of the meeting, shall be given by the Property Trustee
  pursuant to Section 1008 to each Preferred Securityholder of record, at his
  registered address, at least 15 days and not more than 90 days before the
  meeting.  At any such meeting, any business properly before the meeting may be
  so considered whether or not stated in the notice of the meeting.  Any
  adjourned meeting may be held as adjourned without further notice.

  SECTION 603.   Meetings of Preferred Securityholders.
                 -------------------------------------

            No annual meeting of Securityholders is required to be held.  The
  Administrative Trustees, however, shall call a meeting of Securityholders to
  vote on any matter upon the written request of the Preferred Securityholders
  of record of 25% of the Preferred Securities (based upon their Liquidation
  Amount) and the Administrative Trustees or the Property Trustee may, at any
  time in their discretion, call a meeting of Preferred Securityholders to vote
  on any matters as to which Preferred Securityholders are entitled to vote.

            Preferred Securityholders of record of 50% of the Outstanding
  Preferred Securities (based upon their Liquidation Amount), present in person
  or by proxy, shall constitute a quorum at any meeting of Securityholders.

            If a quorum is present at a meeting, an affirmative vote by the
  Preferred Securityholders of record present, in person or by proxy, holding
  more than a majority of the Preferred Securities (based upon their Liquidation
  Amount) held by the Preferred Securityholders of record present, either in
  person or by proxy, at such meeting shall constitute the action of the
  Securityholders, unless this Trust Agreement requires a greater number of
  affirmative votes.

  SECTION 604.   Voting Rights
                 -------------

            Securityholders shall be entitled to one vote for each $25 of
  Liquidation Amount represented by their Trust Securities in respect of any
  matter as to which such Securityholders are entitled to vote.

                                      36


<PAGE>
 
  SECTION 605.   Proxies, etc.
                 -------------      

            At any meeting of Securityholders, any Securityholder entitled to
  vote thereat may vote by proxy, provided that no proxy shall be voted at any
  meeting unless it shall have been placed on file with the Administrative
  Trustees, or with such other officer or agent of the Trust as the
  Administrative Trustees may direct, for verification prior to the time at
  which such vote shall be taken.  Pursuant to a resolution of the Property
  Trustee, proxies may be solicited in the name of the Property Trustee or one
  or more officers of the Property Trustee.  Only Securityholders of record
  shall be entitled to vote.  When Trust Securities are held jointly by several
  persons, any one of them may vote at any meeting in person or by proxy in
  respect of such Trust Securities, but if more than one of them shall be
  present at such meeting in person or by proxy, and such joint owners or their
  proxies so present disagree as to any vote to be cast, such vote shall not be
  received in respect of such Trust Securities.  A proxy purporting to be
  executed by or on behalf of a Securityholder shall be deemed valid unless
  challenged at or prior to its exercise, and the burden of proving invalidity
  shall rest on the challenger.  No proxy shall be valid more than three years
  after its date of execution.

  SECTION 606.    Securityholder Action by Written Consent.
                  ----------------------------------------

            Any action which may be taken by Securityholders at a meeting may be
  taken without a meeting if Securityholders holding more than a majority of all
  Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
  vote in respect of such action (or such larger proportion thereof as shall be
  required by any express provision of this Trust Agreement) shall consent to
  the action in writing.

  SECTION 607.    Record Date for Voting and Other Purposes
                  -----------------------------------------

            For the purposes of determining the Securityholders who are entitled
  to notice of and to vote at any meeting or by written consent, or to
  participate in any distribution on the Trust Securities in respect of which a
  record date is not otherwise provided for in this Trust Agreement, or for the
  purpose of any other action, the Administrative Trustees may from time to time
  fix a date, not more than 90 days prior to the date of any meeting of
  Securityholders or the payment of a distribution or other action, as the case
  may be, as a record date for the determination of the identity of the
  Securityholders of record for such purposes.

  SECTION 608.    Acts of Securityholders
                  -----------------------

            Any request, demand, authorization, direction, notice, consent,
  waiver or other action provided or permitted by this Trust Agreement to be
  given, made or taken by Securityholders or Owners may be embodied in and
  evidenced by one or more instruments of substantially similar tenor signed by
  such Securityholders or Owners in person or by an agent duly appointed in
  writing; and, except as otherwise expressly provided herein, such action shall
  become effective when such instrument or instruments are delivered to an
  Administrative Trustee.  Such instrument or instruments (and the action
  embodied therein and evidenced thereby) are herein sometimes referred to as
  the "Act" of the Securityholders or Owners signing such instrument or
  instruments.  Proof of execution of any such instrument or of a writing
  appointing any such agent shall be sufficient for any purpose of this Trust
  Agreement and (subject to Section 801) conclusive in favor of the Trustees, if
  made in the manner provided in this Section.

            The fact and date of the execution by any Person of any such
  instrument or writing may be proved by the affidavit of a witness of such
  execution or by a certificate of a notary public or other officer authorized
  by law to take acknowledgments of deeds, certifying that the individual
  signing such instrument or writing acknowledged to him the execution thereof.
  Where such execution is by a signer acting in a capacity other than his
  individual capacity, such certificate or affidavit shall also constitute
  sufficient proof of his authority.  The fact and date of the execution of any
  such instrument or writing, or the authority of the Person executing the same,
  may also be proved in any other manner which any Trustee receiving the same
  deems sufficient.

            The ownership of Preferred Securities shall be proved by the
  Securities Register.

            Any request, demand, authorization, direction, notice, consent,
  waiver or other Act of the Securityholder of any Trust Security shall bind
  every future Securityholder of the same Trust Security and the Securityholder
  of every Trust Security issued upon the registration of transfer thereof or in
  exchange therefor or in lieu thereof in respect of anything done, omitted or
  suffered to be done by the Trustees or the Trust in reliance thereon, whether
  or not notation of such action is made upon such Trust Security.

                                      38


<PAGE>
 
            Without limiting the foregoing, a Securityholder entitled hereunder
  to take any action hereunder with regard to any particular Trust Security may
  do so with regard to all or any part of the Liquidation Amount of such Trust
  Security or by one or more duly appointed agents each of which may do so
  pursuant to such appointment with regard to all or any part of such
  liquidation amount.

            If any dispute shall arise between the Securityholders and the
  Administrative Trustees or among such Securityholders or Trustees with respect
  to the authenticity, validity or binding nature of any request, demand,
  authorization, direction, consent, waiver or other Act of such Securityholder
  or Trustee under this Article VI, then the determination of such matter by the
  Property Trustee shall be conclusive with respect to such matter.

            A Securityholder may institute a legal proceeding directly against
  the Depositor under the Guarantee to enforce its rights under the Guarantee
  without first instituting a legal proceeding against the Guarantee Trustee (as
  defined in the Guarantee), the Trust or any person or entity.

  SECTION 609.    Inspection of Records
                  ---------------------

            Upon reasonable notice to the Administrative Trustees and the
  Property Trustee, the records of the Trust shall be open to inspection by
  Securityholders during normal business hours for any purpose reasonably
  related to such Securityholder's interest as a Securityholder.

                  Trustee and the Delaware Trustee.
                  ---------------------------------


            The Bank, the Property Trustee and the Delaware Trustee, each
  severally on behalf of and as to itself, hereby represents and warrants for
  the benefit of the Depositor and the Securityholders that:

            (a)  the Bank is a Delaware banking corporation duly organized,
       validly existing and in good standing under the laws of the State of
       Delaware;

            (b)  the Bank has full corporate power, authority and legal
       right to execute, deliver and perform its

                                      39 


<PAGE>
 
       obligations under this Trust Agreement and has taken all necessary action
       to authorize the execution, delivery and performance by it of this Trust
       Agreement;

            (c)  this Trust Agreement has been duly authorized, executed and
       delivered by the Bank and constitutes the valid and legally binding
       agreement of the Bank enforceable against it in accordance with its
       terms, subject to bankruptcy, insolvency, fraudulent transfer,
       reorganization, moratorium and similar laws of general applicability
       relating to or affecting creditors' rights and to general equity
       principles;

            (d)  the execution, delivery and performance by the Bank of this
       Trust Agreement has been duly authorized by all necessary corporate or
       other action on the part of the Bank, the Property Trustee and the
       Delaware Trustee and does not require any approval of stockholders of the
       Bank and such execution, delivery and performance will not (i) violate
       the Bank's charter or by-laws, (ii) violate any provision of, or
       constitute, with or without notice or lapse of time, a default under, or
       result in the creation or imposition of, any Lien on any properties
       included in the Trust Property pursuant to the provisions of, any
       indenture, mortgage, credit agreement, license or other agreement or
       instrument to which the Property Trustee, the Bank or the Delaware
       Trustee is a party or by which it is bound, or (iii) violate any law,
       governmental rule or regulation of the United States or the State of
       Delaware, as the case may be, governing the banking or trust powers of
       the Bank, the Property Trustee or the Delaware Trustee (as appropriate in
       context) or any order, judgment or decree applicable to the Property
       Trustee, the Bank or the Delaware Trustee;

            (e)  neither the authorization, execution or delivery by the
       Bank of this Trust Agreement nor the consummation of any of the
       transactions by the Bank, the Property Trustee or the Delaware Trustee
       (as appropriate in context) contemplated herein or therein requires the
       consent or approval of, the giving of notice to, the registration with or
       the taking of any other action with respect to any governmental authority
       or agency under any existing federal law governing the banking or trust
       powers of the Bank, the Property Trustee or the Delaware Trustee, as the
       case may be, under the laws of the United States or the State of
       Delaware;

                                      40


<PAGE>
 
            (f)  there are no proceedings pending or, to the best of each of
       the Bank's, the Property Trustee's and the Delaware Trustee's knowledge,
       threatened against or affecting the Bank, the Property Trustee or the
       Delaware Trustee in any court or before any governmental authority,
       agency or arbitration board or tribunal which, individually or in the
       aggregate, would materially and adversely affect the Trust or would
       question the right, power and authority of the Bank, the Property Trustee
       or the Delaware Trustee, as the case may be, to enter into or perform its
       obligations as one of the Trustees under this Trust Agreement.

  SECTION 702.   Representations and Warranties of Depositor.
                 ------------------------------------------- 


            The Depositor hereby represents and warrants for the benefit of the
  Securityholders that:

            (a) the Trust Securities Certificates issued at each Time of
       Delivery on behalf of the Trust have been duly authorized and will have
       been duly and validly executed, issued and delivered by the Trustees
       pursuant to the terms and provisions of, and in accordance with the
       requirements of, this Trust Agreement and the Securityholders will be, as
       of such date, entitled to the benefits of this Trust Agreement; and

            (b) there are no taxes, fees or other governmental charges payable
       by the Trust (or the Trustees on behalf of the Trust) under the laws of
       the State of Delaware or any political subdivision thereof in connection
       with the execution, delivery and performance by the Bank, the Property
       Trustee or the Delaware Trustee, as the case may be, of this Trust
       Agreement.

                                 ARTICLE VIII
                                 ------------
                                 The Trustees
                                 ------------

  SECTION 801.   Certain Duties and Responsibilities
                 -----------------------------------

            (a)  The duties and responsibilities of the Trustees shall be as
     provided by this Trust Agreement and, in the case of the Property Trustee,
     by the Trust Indenture Act.  Notwithstanding the foregoing, no provision of
     this Trust Agreement shall require the Trustees to expend or risk their own
     funds or otherwise incur any financial liability in the performance of any
     of their duties hereunder, or in the exercise of any of their rights or
     powers, if they shall have reasonable grounds for believing that repayment
     of such funds or adequate indemnity against such risk or liability

                                      41 


<PAGE>
 
     is not reasonably assured to it. Whether or not therein expressly so
     provided, every provision of this Trust Agreement relating to the conduct
     or affecting the liability of or affording protection to the Trustees shall
     be subject to the provisions of this Section. Nothing in this Trust
     Agreement shall be construed to release the Property Trustee from liability
     for its own negligent action, its own negligent failure to act, or its own
     willful misconduct. To the extent that, at law or in equity, an
     Administrative Trustee has duties (including fiduciary duties) and
     liabilities relating thereto to the Trust or to the Securityholders, such
     Administrative Trustee shall not be liable to the Trust or to any
     Securityholder for such Trustee's good faith reliance on the provisions of
     this Trust Agreement. The provisions of this Trust Agreement, to the extent
     that they restrict the duties and liabilities of the Administrative
     Trustees otherwise existing at law or in equity, are agreed by the
     Depositor and the Securityholders to replace such other duties and
     liabilities of the Administrative Trustees.

            (b)   All payments made by the Property Trustee or a Paying Agent
     in respect of the Trust Securities shall be made only from the revenue and
     proceeds from the Trust Property and only to the extent that there shall be
     sufficient revenue or proceeds from the Trust Property to enable the
     Property Trustee or a Paying Agent to make payments in accordance with the
     terms hereof.  Each Securityholder, by its acceptance of a Trust Security,
     agrees that it will look solely to the revenue and proceeds from the Trust
     Property to the extent legally available for distribution to it as herein
     provided and that the Trustees are not personally liable to it for any
     amount distributable in respect of any Trust Security or for any other
     liability in respect of any Trust Security.  This Section 801(b) does not
     limit the liability of the Trustees expressly set forth elsewhere in this
     Trust Agreement or, in the case of the Property Trustee, in the Trust
     Indenture Act.

            (c)  No provision of this Trust Agreement shall be construed to
     relieve the Property Trustee from liability for its own negligent action,
     its own negligent failure to act, or its own willful misconduct, except
     that:

            (i)  the Property Trustee shall not be liable for any error      
       of judgment made in good faith by an authorized officer of the Property
       Trustee, unless it shall be proved that the Property Trustee was

       custody, safe keeping and physical preservation of the Debentures and the
       Payment Account shall be to deal with such Property in a similar manner
       as the Property Trustee deals with similar property for its own account,
       subject to the protections and limitations on liability afforded to the
       Property Trustee under this Trust Agreement and the Trust Indenture Act;

       acting or refraining from acting in good faith upon any resolution,
       Opinion of Counsel, certificate, written representation of a Holder or
       transferee, certificate of auditors or any other certificate, statement,
       instrument, opinion, report, notice, request, consent, order, appraisal,
       bond, debenture, note, other evidence of indebtedness or other paper or
       document believed by it to be genuine and to have been signed or

       of the Depositor within ten Business Days after it has delivered such
       notice, or such reasonably shorter period of time set forth in such
       notice (which to the extent practicable shall not be less than two
       Business Days), it may, but shall be under no duty to, take or refrain
       from taking such action not inconsistent with this Trust Agreement as it
       shall deem advisable and in the best interests of the Securityholders, in
       which event the Property Trustee shall have no liability except for its
       own bad faith, negligence or willful misconduct;

            (c)  any direction or act of the Depositor or the Administrative
       Trustees contemplated by this Trust

       Property Trustee (unless other evidence is herein specifically
       prescribed) may, in the absence of bad faith on its part, request and

       Trustees;

       recording, filing or registration of any instrument (including any
       financing or continuation statement or any filing under tax or securities
       laws) or any rerecording, refiling or reregistration thereof;

            (f)  the Property Trustee may consult with counsel (which
       counsel may be counsel to the Depositor or any of its Affiliates, and may
       include any of its employees) and the advice of such counsel shall be
       full and complete authorization and protection in respect of any action
       taken, suffered or omitted by it hereunder in good faith and in reliance
       thereon and in accordance with such advice; the Property Trustee shall
       have the right at any time to seek instructions concerning the
       administration of this Trust Agreement from any court of competent
       jurisdiction;

            (g)  the Property Trustee shall be under no obligation to
       exercise any of the rights or powers vested in it by this Trust Agreement
       at the request or direction of any of the Securityholders pursuant to
       this Trust Agreement, unless such Securityholders shall have offered to
       the Property Trustee reasonable security or indemnity against the costs,
       expenses and liabilities which might be incurred by it in compliance with
       such request or direction;

            (h)  the Property Trustee shall not be bound to make any

       respect to enforcing any remedy or right or taking any other action
       hereunder the Property Trustee (i) may request instructions from the

       action until such instructions are received, and (iii) shall be protected
       in acting in accordance with such instructions; and

       Agreement, the Property Trustee shall not be under any obligation to take

  right, power, duty or obligation conferred or imposed on it, in any
  jurisdiction in which it shall be illegal, or in which the Property Trustee
  shall be unqualified or incompetent in accordance with applicable law, to

                 ------------------- 


            Except as provided in the definition of the term "Outstanding" in
  Article I, any Trustee or any other agent of any Trustee or the Trust, in its
  individual or any other capacity, may become the owner or pledgee of Trust
  Securities and, subject to Sections 808 and 813, may otherwise deal with the
  Trust with the same rights it would have if it were not a Trustee or such
  other agent.

  SECTION 806.   Compensation; Indemnity; Fees.
                 ----------------------------- 


            The Depositor agrees:

            (a)  to pay to the Trustees from time to time reasonable

       the compensation of a trustee of an express trust);

            (b)  except as otherwise expressly provided herein, to

  SECTION 807.   Corporate Property Trustee Required; Eligibility of
                 ---------------------------------------------------
                 Trustees
                 --------

            (a)  There shall at all times be a Property Trustee hereunder
     with respect to the Trust Securities.  The Property Trustee shall be a
     Person that is eligible pursuant to the Trust Indenture Act to act as such
     and has a combined capital and surplus of at least $50,000,000.  If any
     such Person publishes reports of condition at least annually, pursuant to
     law or to the requirements of its supervising or examining authority, then
     for the purposes of this Section, the combined capital and surplus of such
     Person shall be deemed to be its combined capital and surplus as set forth
     in its most recent report of condition so published.  If at any time the
     Property Trustee with respect to the Trust Securities shall cease to be
     eligible in accordance with the provisions of this Section, it shall resign
     immediately in the manner and with the effect hereinafter specified in this
     Article.

            (b)  There shall at all times be one or more Administrative
     Trustees hereunder with respect to the Trust Securities.  Each
     Administrative Trustee shall be either a natural person who is at least 21
     years of age or a legal entity that shall act through one or more persons
     authorized to bind that entity.

            (c)  There shall at all times be a Delaware Trustee with
     respect to the Trust Securities.  The Delaware Trustee shall either be (i)
     a natural person who is at least 21 years of age and a resident of the
     State of Delaware or (ii) a legal entity with its principal place of
     business in the State of Delaware and that otherwise meets the requirements
     of applicable Delaware law that shall act through one or more persons
     authorized to bind such entity.

  SECTION 808.   Conflicting Interests.
                 ---------------------

            If the Property Trustee has or shall acquire a conflicting interest
  within the meaning of the Trust Indenture Act, the Property Trustee shall
  either eliminate such interest or resign, to the extent and in the manner
  provided by, and subject to the provisions of, the Trust Indenture Act and
  this Trust Agreement.

  SECTION 809.   Co-Trustees and Separate Trustee.
                 -------------------------------- 

            Unless an Event of Default shall have occurred and be continuing, at
  any time or times, for the purpose of meeting the legal requirements of the
  Trust Indenture Act or of any jurisdiction in which any part of the Trust
  Property 

                                      48


<PAGE>
 
  may at the time be located, the Depositor and the Administrative Trustees, 
  by agreed action of the majority of such Trustees, shall have power to 
  appoint, and upon the written request of the Administrative Trustees, the
  Depositor shall for such purpose join with the Administrative Trustees in the
  execution, delivery and performance of all instruments and agreements
  necessary or proper to appoint, one or more Persons approved by the Property
  Trustee either to act as co-trustee, jointly with the Property Trustee, of all
  or any part of such Trust Property, or to the extent required by law to act as
  separate trustee of any such property, in either case with such powers as may
  be provided in the instrument of appointment, and to vest in such Person or
  Persons in the capacity aforesaid, any property, title, right or power deemed
  necessary or desirable, subject to the other provisions of this Section.  If
  the Depositor does not join in such appointment within 15 days after the
  receipt by it of a request so to do, or in case a Debenture Event of Default
  has occurred and is continuing, the Property Trustee alone shall have power to
  make such appointment.  Any co-trustee or separate trustee appointed pursuant
  to this Section shall either be (i) a natural person who is at least 21 years
  of age and a resident of the United States or (ii) a legal entity with its
  principal place of business in the United States that shall act through one or
  more persons authorized to bind such entity.

            Should any written instrument from the Depositor be required by any
  co-trustee or separate trustee so appointed for more fully confirming to such
  co-trustee or separate trustee such property, title, right, or power, any and
  all such instruments shall, on request, be executed, acknowledged and
  delivered by the Depositor.

            Every co-trustee or separate trustee shall, to the extent permitted
  by law, but to such extent only, be appointed subject to the following terms,
  namely:

            (a)  The Trust Securities shall be executed and delivered and
       all rights, powers, duties and obligations hereunder in respect of the
       custody of securities, cash and other personal property held by, or
       required to be deposited or pledged with, the Trustees specified
       hereunder, shall be exercised, solely by such Trustees and not by such
       co-trustee or separate trustee.

            (b)  The rights, powers, duties and obligations hereby
       conferred or imposed upon the Property Trustee in respect of any property
       covered by such appointment

                                      49


<PAGE>
 
       shall be conferred or imposed upon and exercised or performed by the
       Property Trustee or by the Property Trustee and such co-trustee or
       separate trustee jointly, as shall be provided in the instrument
       appointing such co-trustee or separate trustee, except to the extent that
       under any law of any jurisdiction in which any particular act is to be
       performed, the Property Trustee shall be incompetent or unqualified to
       perform such act, in which event such rights, powers, duties and
       obligations shall be exercised and performed by such co-trustee or
       separate trustee.

            (c)  The Property Trustee at any time, by an instrument in
       writing executed by it, with the written concurrence of the Depositor,
       may accept the resignation of or remove any co-trustee or separate
       trustee appointed under this Section, and, in case a Debenture Event of
       Default has occurred and is continuing, the Property Trustee shall have
       power to accept the resignation of, or remove, any such co-trustee or
       separate trustee without the concurrence of the Depositor.  Upon the
       written request of the Property Trustee, the Depositor shall join with
       the Property Trustee in the execution, delivery and performance of all
       instruments and agreements necessary or proper to effectuate such
       resignation or removal.  A successor to any co-trustee or separate
       trustee so resigned or removed may be appointed in the manner provided in
       this Section.

            (d)  No co-trustee or separate trustee hereunder shall be
       personally liable by reason of any act or omission of the Property
       Trustee or any other trustee hereunder.

            (e)  The Property Trustee shall not be liable by reason of any
       act of a co-trustee or separate trustee.

            (f)  Any Act of Holders delivered to the Property Trustee shall
       be deemed to have been delivered to each such co-trustee and separate
       trustee.

  SECTION 810.  Resignation and Removal; Appointment of Successor.
                ------------------------------------------------- 

            No resignation or removal of any Trustee (the "Relevant Trustee")
  and no appointment of a successor Trustee pursuant to this Article shall
  become effective until the acceptance of appointment by the successor Trustee
  in accordance with the applicable requirements of Section 811.

                                      50


<PAGE>
 
            Subject to the immediately preceding paragraph, the Relevant Trustee
  may resign at any time with respect to the Trust Securities by giving written
  notice thereof to the Securityholders.  If the instrument of acceptance by the
  successor Trustee required by Section 811 shall not have been delivered to the
  Relevant Trustee within 30 days after the giving of such notice of
  resignation, the Relevant Trustee may petition, at the expense of the Company,
  any court of competent jurisdiction for the appointment of a successor
  Relevant Trustee with respect to the Trust Securities.

            Unless a Debenture Event of Default shall have occurred and be
  continuing, any Trustee may be removed at any time by Act of the Common
  Securityholder.  If a Debenture Event of Default shall have occurred and be
  continuing, the Property Trustee or the Delaware Trustee, or both of them, may
  be removed at such time by Act of the Holders of a majority in Liquidation
  Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
  individual capacity and on behalf of the Trust).  An Administrative Trustee
  may be removed by the Common Securityholder at any time.

            If any Trustee shall resign, be removed or become incapable of
  acting as Trustee, or if a vacancy shall occur in the office of any Trustee
  for any cause, at a time when no Debenture Event of Default shall have
  occurred and be continuing, the Common Securityholder, by Act of the Common
  Securityholder delivered to the retiring Trustee, shall promptly appoint a
  successor Trustee or Trustees with respect to the Trust Securities and the
  Trust, and the successor Trustee shall comply with the applicable requirements
  of Section 811.  If the Property Trustee or the Delaware Trustee shall resign,
  be removed or become incapable of continuing to act as the Property Trustee or
  the Delaware Trustee, as the case may be, at a time when a Debenture Event of
  Default shall have occurred and be continuing, the Preferred Securityholders,
  by Act of the Securityholders of a majority in Liquidation Amount of the
  Preferred Securities then Outstanding delivered to the retiring Relevant
  Trustee, shall promptly appoint a successor Relevant Trustee or Trustees with
  respect to the Trust Securities and the Trust, and such successor Trustee
  shall comply with the applicable requirements of Section 811.  If an
  Administrative Trustee shall resign, be removed or become incapable of acting
  as Administrative Trustee, at a time when a Debenture Event of Default shall
  have occurred and be continuing, the Common Securityholder, by Act of the
  Common Securityholder delivered to the Administrative Trustee, shall promptly
  appoint a successor Administrative

                                      51


<PAGE>
 
  Trustee or Administrative Trustees with respect to the Trust Securities and
  the Trust, and such successor Administrative Trustee or Administrative
  Trustees shall comply with the applicable requirements of Section 811. If no
  successor Relevant Trustee with respect to the Trust Securities shall have
  been so appointed by the Common Securityholder or the Preferred
  Securityholders and accepted appointment in the manner required by Section
  811, any Securityholder who has been a Securityholder of Trust Securities for
  at least six months may, on behalf of himself and all others similarly
  situated, petition any court of competent jurisdiction for the appointment of
  a successor Relevant Trustee with respect to the Trust Securities.

            The Property Trustee shall give notice of each resignation and each
  removal of a Trustee and each appointment of a successor Trustee to all
  Securityholders in the manner provided in Section 1008 and shall give notice
  to the Depositor.  Each notice shall include the name of the successor
  Relevant Trustee and the address of its Corporate Trust Office if it is the
  Property Trustee.

            Notwithstanding the foregoing or any other provision of this Trust
  Agreement, in the event any Administrative Trustee or a Delaware Trustee who
  is a natural person dies or becomes, in the opinion of the Depositor,
  incompetent or incapacitated, the vacancy created by such death, incompetence
  or incapacity may be filled by (a) the unanimous act of remaining
  Administrative Trustees if there are at least two of them or (b) otherwise by
  the Depositor (with the successor in each case being a Person who satisfies
  the eligibility requirement for Administrative Trustees set forth in Section
  807).

  SECTION 811.  Acceptance of Appointment by Successor.
                -------------------------------------- 

            In case of the appointment hereunder of a successor Trustee such
  successor Trustee so appointed shall execute, acknowledge and deliver to the
  Trust and to the retiring Trustee an instrument accepting such appointment,
  and thereupon the resignation or removal of the retiring Trustee shall become
  effective and such successor Trustee, without any further act, deed or
  conveyance, shall become vested with all the rights, powers, trusts and duties
  of the retiring Trustee; but, on the request of the Depositor or the successor
  Trustee, such retiring Trustee shall, upon payment of its charges, execute and
  deliver an instrument transferring to such successor Trustee all the rights,
  powers and trusts of the retiring Trustee and if the Property Trustee is the
  resigning Trustee shall duly assign,

                                      52


<PAGE>
 
  transfer and deliver to the successor Trustee all property and money held by
  such retiring Property Trustee hereunder.

            In case of the appointment hereunder of a successor Relevant Trustee
  with respect to the Trust Securities and the Trust, the retiring Relevant
  Trustee and each successor Relevant Trustee with respect to the Trust
  Securities shall execute and deliver an amendment hereto wherein each
  successor Relevant Trustee shall accept such appointment and which (a) shall
  contain such provisions as shall be necessary or desirable to transfer and
  confirm to, and to vest in, each successor Relevant Trustee all the rights,
  powers, trusts and duties of the retiring Relevant Trustee with respect to the
  Trust Securities and the Trust and (b) shall add to or change any of the
  provisions of this Trust Agreement as shall be necessary to provide for or
  facilitate the administration of the trusts hereunder by more than one
  Relevant Trustee, it being understood that nothing herein or in such amendment
  shall constitute such Relevant Trustees co-trustees of the same trust and that
  each such Relevant Trustee shall be trustee of a trust or trusts hereunder
  separate and apart from any trust or trusts hereunder administered by any

            (b)  If a Trustee ceases to hold office for any reason and the

                     -------------------------------------

  SECTION 901.  Termination Upon Expiration Date.
                 ------------------------------- 

            Unless earlier terminated, the Trust shall automatically terminate

  the Trust Property in accordance with Section 904.

                                      56


<PAGE>
 
  SECTION 902.  Early Termination.
                ----------------- 

            The first to occur of any of the following events is an "Early

            (a)  the occurrence of a Bankruptcy Event in respect of, or the
       dissolution or liquidation of, the Depositor;

            (b)  the written direction to the Property Trustee from the

            (c)  the redemption of all of the Preferred Securities in
       connection with the redemption of all of the Debentures; and

            (d)  the entry of an order for dissolution of the Trust by a
       court of competent jurisdiction.

  SECTION 903.  Termination.
                ----------- 

            The respective obligations and responsibilities of the Trustees and
  the Trust created and continued hereby shall terminate upon the latest to
  occur of the following:  (a) the distribution by the Property Trustee to
  Securityholders upon the liquidation of the Trust pursuant to Section 904, or
  upon the redemption of all of the Trust Securities pursuant to Section 402, of
  all amounts required to be distributed hereunder upon the final payment of the
  Trust Securities; (b) the payment of any expenses owed by the Trust; and (c)
  the discharge of all administrative duties of the Administrative Trustees,
  including the performance of any tax reporting obligations with respect to the
  Trust or the Securityholders.

  SECTION 904.  Liquidation.

            (a)  If an Early Termination Event specified in clause (a), (b)
     or (d) of Section 902 occurs or upon the Expiration Date, the Trust shall
     be liquidated by the Trustees as expeditiously as the Trustees determine to
     be possible by distributing, after satisfaction of liabilities to creditors
     of the Trust as provided by applicable law, to each Securityholder a Like
     Amount of Debentures, subject to Section 904(d).  Notice of liquidation
     shall be given by the Property Trustee by first-class mail, postage
     prepaid, mailed not later than 30 nor more than 60 days prior to the
     Liquidation Date to each Holder of Trust Securities at such

<PAGE>
 
     Holder's address appearing in the Securities Register. All notices of
     liquidation shall:

              (i)  state the Liquidation Date;
                   --------------------------

             (ii)  state that from and after the Liquidation Date, the
       Trust Securities will no longer be deemed to be Outstanding and any Trust
       Securities Certificates not surrendered for exchange will be deemed to
       represent a Like Amount of Debentures; and

            (iii)   provide such information with respect to the mechanics by
       which Holders may exchange Trust Securities Certificates for Debentures,
       or if Section 904(d) applies receive a Liquidation Distribution, as the
       Administrative Trustees or the Property Trustee shall deem appropriate.
      
              (b)  Except where Section 902(c) or 904(d) applies, in order to
     effect the liquidation of the Trust and distribution of the Debentures to
     Securityholders, the Property Trustee shall establish a record date for
     such distribution (which shall be not more than 45 days prior to the
     Liquidation Date) and, either itself acting as exchange agent or through
     the appointment of a separate exchange agent, shall establish such
     procedures as it shall deem appropriate to effect the distribution of
     Debentures in exchange for the Outstanding Trust Securities Certificates.

              (c)  Except where Section 902(c) or 904(d) applies, after the
     Liquidation Date, (i) the Trust Securities will no longer be deemed to be
     Outstanding, (ii) certificates representing a Like Amount of Debentures
     will be issued to holders of Trust Securities Certificates, upon surrender
     of such certificates to the Administrative Trustees or their agent for
     exchange, (iii) the Depositor shall use its reasonable efforts to have the
     Debentures listed on the New York Stock Exchange or on such other stock
     exchange, interdealer quotation system or self-regulatory organization as
     the Preferred Securities are then listed or traded, (iv) any Trust
     Securities Certificates not so surrendered for exchange will be deemed to
     represent a Like Amount of Debentures, accruing interest at the rate
     provided for in the Debentures from the last Distribution Date on which a
     Distribution was made on such Trust Securities Certificates until such
     certificates are so surrendered (and until such certificates are so
     surrendered, no payments of interest or principal will be made to holders
     of Trust Securities Certificates with respect to such Debentures), and (v)
     all rights of Securityholders holding Trust Securities will cease, except
     the right of such 

                                      58

     Securityholders to receive Debentures upon surrender of Trust Securities
     Certificates.

            (d)  In the event that, notwithstanding the other provisions of
     this Section 904, whether because of an order for dissolution entered by a
     court of competent jurisdiction or otherwise, distribution of the
     Debentures in the manner provided herein is determined by the Property
     Trustee not to be practical, the Trust Property shall be liquidated, and
     the Trust shall be dissolved, wound-up or terminated, by the Property
     Trustee in such manner as the Property Trustee determines.  In such event,
     on the date of the dissolution, winding-up or other termination of the
     Trust, Securityholders will be entitled to receive out of the assets of the
     Trust available for distribution to Securityholders, after satisfaction of
     liabilities to creditors of the Trust as provided by applicable law, an
     amount equal to the Liquidation Amount per Trust Security plus accumulated
     and unpaid Distributions thereon to the date of payment (such amount being
     the "Liquidation Distribution").  If, upon any such dissolution, winding-up
     or termination, the Liquidation Distribution can be paid only in part
     because the Trust has insufficient assets available to pay in full the
     aggregate Liquidation Distribution, then, subject to the next succeeding
     sentence, the amounts payable by the Trust on the Trust Securities shall be
     paid on a pro rata basis (based upon Liquidation Amounts).  The holder of
     the Common Securities will be entitled to receive Liquidation Distributions
     upon any such dissolution, winding-up or termination pro rata (determined
     as aforesaid) with Holders of Preferred Securities, except that, if a
     Debenture Event of Default has occurred and is continuing, the Preferred
     Securities shall have a priority over the Common Securities.

                   --------------------------------------------------------- 
                   the Trust.  
                   --------- 

            The Trust may not merge with or into, consolidate, amalgamate, or be
  replaced by, or convey, transfer or lease its properties and assets
  substantially as an entirety to any corporation or other body, except pursuant
  to this Section 905.  At the request of the Depositor, with the consent of the
  Administrative Trustees and without the consent of the holders of the
  Preferred Securities, the Trust may merge with or into, consolidate,
  amalgamate, or be replaced by or convey, transfer or lease its properties and
  assets substantially as an entirety to a trust organized as such under the
  laws of any state; provided, that (i) such successor entity either (a)
                     --------                                           
  expressly assumes all of the obligations of the Trust with respect to the
  Preferred

<PAGE>
 
  Securities or (b) substitutes for the Preferred Securities other
  securities having substantially the same terms as the Preferred Securities
  (the "Successor Securities") so long as the Successor Securities rank the same
  as the Preferred Securities rank in priority with respect to distributions and
  payments upon liquidation, redemption and otherwise, (ii) the Depositor
  expressly appoints a trustee of such successor entity possessing the same
  powers and duties as the Property Trustee as the holder of the Debentures,
  (iii) the Successor Securities are listed or traded, or any Successor
  Securities will be listed upon notification of issuance, on any national
  securities exchange or other organization on which the Preferred Securities
  are then listed or traded, if any, (iv) such merger, consolidation,
  amalgamation, replacement, conveyance, transfer or lease does not cause the
  Preferred Securities (including any Successor Securities) to be downgraded by
  any nationally recognized statistical rating organization, (v) such merger,
  consolidation, amalgamation, replacement, conveyance, transfer or lease does
  not adversely affect the rights, preferences and privileges of the holders of
  the Preferred Securities (including any Successor Securities) in any material
  respect, (vi) such successor entity has a purpose identical to that of the
  Trust, (vii) prior to such merger, consolidation, amalgamation, replacement,
  conveyance, transfer or lease, the Depositor has received an Opinion of
  Counsel to the effect that (a) such merger, consolidation, amalgamation,
  replacement, conveyance, transfer or lease does not adversely affect the
  rights, preferences and privileges of the holders of the Preferred Securities
  (including any Successor Securities) in any material respect, and (b)
  following such merger, consolidation, amalgamation, replacement, conveyance,
  transfer or lease, neither the Trust nor such successor entity will be
  required to register as an investment company under the 1940 Act and (viii)
  the Depositor owns all of the Common Securities of such successor entity and
  guarantees the obligations of such successor entity under the Successor
  Securities at least to the extent provided by the Guarantee.  Notwithstanding
  the foregoing, the Trust shall not, except with the consent of holders of 100%
  in Liquidation Amount of the Preferred Securities, consolidate, amalgamate,
  merge with or into, be replaced by or convey, transfer or lease its properties
  and assets substantially as an entirety to any other entity or permit any
  other entity to consolidate, amalgamate, merge with or into, or replace it if
  such consolidation, amalgamation, merger, replacement, conveyance, transfer or
  lease would cause the Trust or the successor entity to be classified as other
  than a grantor trust for United States federal income tax purposes.

     or to ensure that the Trust will not be required to register as an
     investment company under the 1940 Act; provided, however, that in the case

     of any Distribution on the Trust Securities or otherwise adversely affect
     the amount of any Distribution required to be made in respect of the Trust
     Securities as of a specified date or (ii) restrict the right of a

     fail or cease to be classified as a grantor trust for United States federal
     income tax purposes.

            (e)  Notwithstanding anything in this Trust Agreement to the

Re:  MCI Capital II ____% Cumulative Quarterly Income Preferred Securities,
     ---------------------------------------------------------------------
     Series A
     --------


Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the MCI
Capital II ___% Cumulative Quarterly Income Preferred Securities, Series A (the
"Preferred Securities"), of MCI Capital II, a Delaware business trust (the
"Issuer"), formed pursuant to a Trust Agreement between MCI Communications
Corporation ("MCI") and Wilmington Trust Company, as Trustee.  The payment of
distributions on the Preferred Securities and payments due upon liquidation of
Issuer or redemption of the Preferred Securities, to the extent the Issuer has
funds available for the payment thereof, are guaranteed by MCI to the extent set
forth in a Guarantee Agreement dated ________ __, 1996 by MCI with respect to
the Preferred Securities.  MCI and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement dated _________ __, 1996 by and among the Underwriters,
the Issuer and MCI, and the Underwriters wish to take delivery of the Preferred
Securities through DTC. Wilmington Trust Company is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:


     1.  Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about ________ __, 1996, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") 

                                       1

<PAGE>
 
registered in the name of DTC's Preferred Securities nominee, Cede & Co.,
representing an aggregate of __________ Preferred Securities and bearing the
following legend:

     Unless this certificate is presented by an authorized representative of The
     Depository Trust Company, a New York corporation ("DTC"), to Issuer or its
     agent for registration of transfer, exchange, or payment, and any
     certificate issued is registered in the name of Cede & Co. or in such other
     name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
     HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
     the registered owner hereof, Cede & Co., has an interest herein.

     2.  The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3.  In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4.  In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying:  (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means 
(e.g., legible telecopy, registered or certified mail, overnight delivery) in a

                                       2
<PAGE>
 
timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before the Publication
Date. The Issuer or the Transfer Agent and Registrar will forward such notice
either in a separate secure transmission for each CUSIP number or in a secure
transmission of multiple CUSIP numbers (if applicable) that includes a manifest
or list of each CUSIP number submitted in that transmission. (The party sending
such notice shall have a method to verify subsequently the use of such means and
the timeliness Of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.

Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4.  Such redemption notice shall be
sent to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190,
and receipt of such notice shall be confirmed by telephoning (516) 227-4070.

of the Preferred Securities, which, as of the date of this letter, is "MCI

     8.  Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in next day funds on

     9.  DTC may by prior written notice direct the Issuer and the Transfer
Agent and Registrar to use any other telecopy number or address of DTC as the
number or address to which notices or payments may be sent.

     10.  In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
             - -                                                              
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion:  

                                       4

<PAGE>
 
(a) may request the Issuer or the Transfer Agent and Registrar to issue and
countersign a new Global Certificate; or (b) may make an appropriate notation on
the Global Certificate indicating the date and amount of such reduction.

     11.  DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law.  Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates.  In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13.  This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

to advance funds on behalf of MCI Capital II.

     or other payment in respect of any such delay), except that, if such
     Business Day falls in the next calendar year, such payment will be made on
     the immediately preceding Business Day, in each case, with the same force
     and effect as if made on such date. In the event that payment of the
     Redemption Price in respect of any Trust Securities called for redemption
     is improperly withheld or refused and not paid either by the Trust or by
     the Depositor pursuant to the Guarantee, Distributions on such Trust
     Securities will continue to accrue, at the then applicable rate, from the
     Redemption Date originally established by the Trust for such Trust
     Securities to the date such Redemption Price is actually paid, in which
     case the actual payment date will be the date fixed for redemption for
     purposes of calculating the Redemption Price.

            (e)  Payment of the Redemption Price on the Trust Securities
     shall be made to the recordholders thereof as they appear on the Securities
     Register for the Trust Securities on the relevant record date, which shall
     be one Business Day prior to the relevant Redemption Date; provided,
                                                                -------- 
     however, that in the event that the Preferred Securities do not remain in
     -------                                                                  
     book-entry-only form, the relevant record date shall be the date fifteen
     days prior to the relevant Redemption Date.

            (f)  Subject to Section 403(a), if less than all the Outstanding
     Trust Securities are to be redeemed on a Redemption Date, then the
     aggregate Liquidation Amount of Trust Securities to be redeemed shall be
     allocated on a pro rata basis (based on Liquidation Amounts) among the
     Common Securities and the Preferred Securities.  The particular Preferred
     Securities to be redeemed shall be selected on a pro rata basis (based upon
     Liquidation Amounts) not more than 60 days prior to the Redemption Date by
     the Property Trustee from the Outstanding Preferred Securities not

                                      23


<PAGE>
 
     previously called for redemption, by such method (including, without
     limitation, by lot) as the Property Trustee shall deem fair and appropriate
     and which may provide for the selection for redemption of portions (equal
     to $25 or an integral multiple of $25 in excess thereof) of the Liquidation
     Amount of Preferred Securities of a denomination larger than $25.  The
     Property Trustee shall promptly notify the Security Registrar in writing of
     the Preferred Securities selected for redemption and, in the case of any
     Preferred Securities selected for partial redemption, the Liquidation
     Amount thereof to be redeemed.  For all purposes of this Trust Agreement,
     unless the context otherwise requires, all provisions relating to the
     redemption of Preferred Securities shall relate, in the case of any
     Preferred Securities redeemed or to be redeemed only in part, to the
     portion of the Liquidation Amount of Preferred Securities that has been or
     is to be redeemed.

     SECTION 403.  Subordination of Common Securities
                   ----------------------------------

            (a)  Payment of Distributions (including Additional Amounts, if
     applicable) on, and the Redemption Price of, the Trust Securities, as
     applicable, shall be made, subject to Section 402(f), pro rata among the
     Common Securities and the Preferred Securities based on the Liquidation
     Amount of the Trust Securities; provided, however, that if on any
                                     --------  -------                
     Distribution Date or Redemption Date any Event of Default resulting from a
     Debenture Event of Default shall have occurred and be continuing, no
     payment of any Distribution (including Additional Amounts, if applicable)
     on, or Redemption Price of, any Common Security, and no other payment on
     account of the redemption, liquidation or other acquisition of Common
     Securities, shall be made unless payment in full in cash of all accumulated
     and unpaid Distributions (including Additional Amounts, if applicable) on
     all Outstanding Preferred Securities for all Distribution periods
     terminating on or prior thereto, or in the case of payment of the
     Redemption Price the full amount of such Redemption Price on all
     Outstanding Preferred Securities, shall have been made or provided for, and
     all funds immediately available to the Property Trustee shall first be
     applied to the payment in full in cash of all Distributions (including
     Additional Amounts, if applicable) on, or the Redemption Price of,
     Preferred Securities then due and payable.

            (b)  In the case of the occurrence of any Event of Default
     resulting from a Debenture Event of Default, the Holder of Common
     Securities will be deemed to have waived any right to act with respect to
     any such Event of Default under this Trust Agreement until the effect of
     all such 

                                      24


<PAGE>
 
     Events of Default with respect to the Preferred Securities have been cured,
     waived or otherwise eliminated. Until any such Event of Default under this
     Trust Agreement with respect to the Preferred Securities has been so cured,
     waived or otherwise eliminated, the Property Trustee shall act solely on
     behalf of the Holders of the Preferred Securities and not the Holder of the
     Common Securities, and only the Holders of the Preferred Securities will
     have the right to direct the Property Trustee to act on their behalf.

     SECTION 404.  Payment Procedures
                   ------------------

            Payments of Distributions (including Additional Amounts, if
  applicable) in respect of the Preferred Securities shall be made by check
  mailed to the address of the Person entitled thereto as such address shall
  appear on the Securities Register or, if the Preferred Securities are held by
  a Clearing Agency, such Distributions shall be made to the Clearing Agency in
  immediately available funds, which shall credit the relevant Persons' accounts
  at such Clearing Agency on the applicable distribution dates.  Payments in
  respect of the Common Securities shall be made in such manner as shall be
  mutually agreed between the Property Trustee and the Common Securityholder.

  at the Depositor's expense, and file all United States federal, state and
  local tax and information returns and reports required to be filed by or in
  respect of the Trust.  In this regard, the Administrative Trustees shall (a)
  prepare and file (or cause to be prepared and filed) the appropriate Internal
  Revenue Service Form required to be filed in respect of the Trust in each
  taxable year of the Trust and (b) prepare and furnish (or cause to be prepared
  and furnished) to each Securityholder the appropriate Internal Revenue Service
  form required to be furnished to such Securityholder or the information
  required to be provided on such form.  The Administrative Trustees shall
  provide the Depositor and the Property Trustee with a copy of all such returns
  and reports promptly after such filing or furnishing.  The Trustees shall
  comply with United States federal withholding and backup withholding tax laws
  and information reporting requirements with respect to any payments to
  Securityholders under the Trust Securities.

  corresponding payment such Holder (and Owner) has directly received pursuant
  to Section 508 of the Indenture.

  Certificates bearing the manual signatures of individuals who were, at the
  time when such signatures shall have been affixed, authorized to sign on
  behalf of the Trust, shall be validly issued and entitled to the benefits of
  this Trust Agreement, notwithstanding that such individuals or any of them
  shall have ceased to be so authorized prior to the delivery of such Trust
  Securities Certificates or did not hold such offices at the date of delivery
  of such Trust Securities Certificates.  A transferee of a Trust Securities
  Certificate shall become a Securityholder, and shall be entitled to the rights
  and subject to the obligations of a Securityholder hereunder, upon due
  registration of such Trust Securities Certificate in such transferee's name
  pursuant to Sections 504, 511 and 513.

  SECTION  504.  Registration of Transfer and Exchange of Preferred Securities
                 -------------------------------------------------------------
                  Certificates
                  ------------

            The Depositor shall keep or cause to be kept, at the office or
  agency maintained pursuant to Section 508, a register or registers for the
  purpose of registering Trust Securities Certificates and transfers and
  exchanges of Preferred Securities Certificates (the "Securities Register") in
  which, the registrar designated by the Depositor (the "Securities Registrar"),

  the registration of Preferred Securities Certificates and Common Securities
  Certificates (subject to Section 510 in the case of the Common Securities
  Certificates) and registration of transfers and exchanges of Preferred
  Securities Certificates as herein provided.  The Bank shall be the initial
  Securities Registrar.

            Upon surrender for registration of transfer of any Preferred
  Securities Certificate at the office or agency maintained pursuant to Section
  508, the Administrative Trustees or any one of them shall execute and deliver,
  in the name of the designated transferee or transferees, one or more new
  Preferred Securities Certificates in authorized denominations of a like
  aggregate Liquidation Amount dated the date of execution by such
  Administrative Trustee or Trustees.  The Securities Registrar shall not be
  required to register the transfer of any Preferred Securities that have been
  called for redemption.  At the option of a Holder, Preferred Securities
  Certificates may be exchanged for other Preferred Securities Certificates in
  authorized denominations of the same class and of a like aggregate Liquidation
  Amount upon surrender of the Preferred Securities Certificates to be exchanged
  at the office or agency maintained pursuant to Section 508.

  registration of transfer or exchange shall be accompanied by a written
  instrument of transfer in form satisfactory to the Property Trustee and the
  Securities Registrar duly executed by the Holder or his attorney duly
  authorized in writing.  Each Preferred Securities Certificate surrendered for
  registration of transfer or exchange shall be cancelled and subsequently
  disposed of by the Property Trustee in accordance with its customary practice.

            No service charge shall be made for any registration of transfer or
  exchange of Preferred Securities Certificates, but the Securities Registrar
  may require payment of a sum sufficient to cover any tax or governmental
  charge that may be imposed in connection with any transfer or exchange of
  Preferred Securities Certificates.

  SECTION  505.  Mutilated, Destroyed, Lost or Stolen Trust Securities
                 -----------------------------------------------------
                 Certificates
                 ------------

         If (a) any mutilated Trust Securities Certificate shall be
  surrendered to the Securities Registrar, or if the Securities Registrar
  shall receive evidence to its satisfaction of the destruction, loss or
  theft of any Trust Securities Certificate and (b) there shall be delivered
  to the Securities Registrar and the Administrative Trustees such security
  or indemnity as may be required by them to save each of them harmless, then
  in the absence of notice that such Trust Securities Certificate shall have
  been acquired by a bona fide purchaser, the Administrative Trustees, or any
  one of them, on behalf of the Trust shall execute and make available for
  delivery, in exchange for or in lieu of any such mutilated, destroyed, lost
  or stolen Trust Securities Certificate, a new Trust Securities Certificate
  of like class, tenor and denomination.  In connection with the issuance of
  any new Trust Securities Certificate under this Section, the Administrative
  Trustees or the Securities Registrar may require the payment of a sum
  sufficient to cover any tax or other governmental charge that may be
  imposed in connection therewith.  Any duplicate Trust Securities
  Certificate issued pursuant to this Section shall constitute conclusive
  evidence of an undivided beneficial interest in the assets of the Trust, as
  if originally issued, whether or not the lost, stolen or destroyed Trust
  Securities Certificate shall be found at any time.

  SECTION 506.    Persons Deemed Securityholders
                  ------------------------------

            The Administrative Trustees or the Securities Registrar shall treat
  the Person in whose name any Trust Securities Certificate shall be registered
  in the Securities Register as the owner of such Trust Securities Certificate
  for the purpose of receiving distributions and for all other purposes
  whatsoever, and neither the Trustees nor the Securities Registrar shall be
  bound by any notice to the contrary.

  SECTION 507.    Access to List of Securityholders' Names and Addresses
                  ------------------------------------------------------

            The Administrative Trustees or the Depositor shall furnish or cause
  to be furnished (a) to the Property Trustee, semi-annually on or before
  January 15 and July 15 in each year, a list, in such form as the Property
  Trustee may reasonably require, of the names and addresses of the
  Securityholders as of the most recent Record Date and (b) to the Property
  Trustee, promptly after receipt by any Administrative Trustee or the Depositor
  of a request therefor from the Property Trustee in order to enable the
  Property Trustee to discharge its obligations under this Trust Agreement, in
  each case to the extent such information is in the possession or control of
  the Administrative Trustees or the Depositor and is not identical to a
  previously supplied list or has not otherwise been received by the Property
  Trustee in its capacity as Securities Registrar.  The rights of
  Securityholders to communicate with other Securityholders with respect to
  their rights under this Trust Agreement or under the Trust Securities, and the
  corresponding rights of the Trustee shall be as provided in the Trust
  Indenture Act.  Each Holder, by receiving and holding a Trust Securities
  Certificate, and each Owner shall be deemed to have agreed not to hold the
  Depositor, the Property Trustee or the Administrative Trustees accountable by
  reason of the disclosure of its name and address, regardless of the source
  from which such information was derived.

  SECTION 508.    Maintenance of Office or Agency
                  -------------------------------

            The Administrative Trustees shall maintain an office or offices or
  agency or agencies where Preferred Securities Certificates may be surrendered
  for registration of transfer or exchange and where notices and demands to or
  upon the Trustees in respect of the Trust Securities Certificates may be
  served.  The Administrative Trustees initially designate MCI Communications
  Corporation, 1801 Pennsylvania Avenue, N.W., Washington, D.C. 20006,
  Attention: Treasurer, as the office for such purposes. The

                                      29

  Administrative Trustees shall give prompt written notice to the Depositor and
  to the Securityholders of any change in the location of the Securities
  Register or any such office or agency.

  SECTION 509.    Appointment of Paying Agent.
                  ---------------------------

            The Paying Agent shall make distributions to Securityholders from
  the Payment Account and shall report the amounts of such distributions to the
  Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
  the revocable power to withdraw funds from the Payment Account for the purpose
  of making the distributions referred to above.  The Administrative Trustees
  may revoke such power and remove the Paying Agent if such Trustees determine
  in their sole discretion that the Paying Agent shall have failed to perform
  its obligations under this Trust Agreement in any material respect.  The
  Paying Agent shall initially be the Bank, and any co-paying agent chosen by
  the Bank and acceptable to the Administrative Trustees and the Depositor.  Any
  Person acting as Paying Agent shall be permitted to resign as Paying Agent
  upon 30 days' written notice to the Administrative Trustees, the Property
  Trustee and the Depositor.  In the event that the Bank shall no longer be the
  Paying Agent or a successor Paying Agent shall resign or its authority to act
  be revoked, the Administrative Trustees shall appoint a successor that is
  acceptable to the Property Trustee and the Depositor to act as Paying Agent
  (which shall be a bank or trust company).  The Administrative Trustees shall
  cause such successor Paying Agent or any additional Paying Agent appointed by
  the Administrative Trustees to execute and deliver to the Trustees an
  instrument in which such successor Paying Agent or additional Paying Agent
  shall agree with the Trustees that as Paying Agent, such successor Paying
  Agent or additional Paying Agent will hold all sums, if any, held by it for
  payment to the Securityholders in trust for the benefit of the Securityholders
  entitled thereto until such sums shall be paid to such Securityholders.  The
  Paying Agent shall return all unclaimed funds to the Property Trustee and upon
  removal of a Paying Agent such Paying Agent shall also return all funds in its
  possession to the Property Trustee.  The provisions of Sections 801, 803 and
  806 shall apply to the Bank also in its role as Paying Agent, for so long as
  the Bank shall act as Paying Agent and, to the extent applicable, to any other
  paying agent appointed hereunder.  Any reference in this Agreement to the
  Paying Agent shall include any co-paying agent unless the context requires
  otherwise.

  SECTION 510.  Ownership of Common Securities by Depositor.
                ------------------------------------------- 

            At each Time of Delivery, the Depositor shall acquire and retain
  beneficial and record ownership of the Common Securities.  To the fullest
  extent permitted by law, other than a transfer in connection with a
  consolidation or merger of the Depositor into another corporation, or any
  conveyance, transfer or lease by the Depositor of its properties and assets
  substantially as an entirety to any Person, pursuant to Section 801 of the
  Indenture, any attempted transfer of the Common Securities shall be void.  The
  Administrative Trustees shall cause each Common Securities Certificate issued
  to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
  TRANSFERABLE".

                ---------------------------------------------------------------
                Certificate.

            (a)  The Preferred Securities Certificates, upon original
     issuance, will be issued in the form of a typewritten Preferred Securities
     Certificate or Certificates representing Book-Entry Preferred Securities
     Certificates, to be delivered to The Depository Trust Company, the initial
     Clearing Agency, by, or on behalf of, the Trust.  Such Preferred Securities
     Certificate or Certificates shall initially be registered on the Securities
     Register in the name of Cede & Co., the nominee of the initial Clearing
     Agency, and no beneficial owner will receive a Definitive Preferred
     Securities Certificate representing such beneficial owner's interest in
     such Preferred Securities, except as provided in Section 513.  Unless and
     until Definitive Preferred Securities Certificates have been issued to
     beneficial owners pursuant to Section 513:

              (i)  the provisions of this Section 511(a) shall be in full
       force and effect;

             (ii)  the Securities Registrar and the Trustees shall be
       entitled to deal with the Clearing Agency for all purposes of this Trust
       Agreement relating to the Book-Entry Preferred Securities Certificates
       (including the payment of the Liquidation Amount of and Distributions on
       the Book-Entry Preferred Securities and the giving of instructions or
       directions to Owners of Book-Entry Preferred Securities) as the sole
       Holder of Book-Entry Preferred Securities and shall have no obligations
       to the Owners thereof;

            (iii)  to the extent that the provisions of this Section 511
       conflict with any other provisions of this

                                      31 


<PAGE>
 
       Trust Agreement, the provisions of this Section 511 shall control; and

             (iv)  the rights of the Owners of the Book-Entry Preferred
       Securities Certificates shall be exercised only through the Clearing
       Agency and shall be limited to those established by law and agreements
       between such Owners and the Clearing Agency and/or the Clearing Agency
       Participants.  Pursuant to the Certificate Depository Agreement, unless
       and until Definitive Preferred Securities Certificates are issued
       pursuant to Section 513, the initial Clearing Agency will make book-entry
       transfers among the Clearing Agency Participants and receive and transmit
       payments on the Preferred Securities to such Clearing Agency
       Participants.

            (b)  A single Common Securities Certificate representing the
     Common Securities shall be issued to the Depositor in the form of a
     definitive Common Securities Certificate.

  SECTION 512.  Notices to Clearing Agency.
                -------------------------- 

            To the extent that a notice or other communication to the Owners is
  required under this Trust Agreement, unless and until Definitive Preferred
  Securities Certificates shall have been issued to Owners pursuant to Section
  513, the Trustees shall give all such notices and communications specified
  herein to be given to Owners to the Clearing Agency, and shall have no
  obligations to the Owners.

  SECTION 513.  Definitive Preferred Securities Certificates.
                -------------------------------------------- 

            If (a) the Depositor advises the Trustees in writing that the
  Clearing Agency is no longer willing or able to properly discharge its
  responsibilities with respect to the Preferred Securities Certificates, and
  the Depositor is unable to locate a qualified successor, (b) the Depositor at
  its option advises the Trustees in writing that it elects to terminate the
  book-entry system through the Clearing Agency, or (c) after the occurrence of
  a Debenture Event of Default, Owners of Preferred Securities Certificates
  representing beneficial interests aggregating at least a majority of the
  Liquidation Amount advise the Property Trustee in writing that the
  continuation of a book-entry system through the Clearing Agency is no longer
  in the best interest of the Owners of Preferred Securities Certificates, then
  the Property Trustee shall notify the Clearing Agency and the Clearing Agency
  shall notify all Owners of Preferred Securities Certificates and the other
  Trustees of the 

                                      32

  occurrence of any such event and of the availability of the Definitive
  Preferred Securities Certificates to Owners of such class or classes, as
  applicable, requesting the same. Upon surrender to the Property Trustee of the
  typewritten Preferred Securities Certificate or Certificates representing the
  Book-Entry Preferred Securities Certificates by the Clearing Agency,
  accompanied by registration instructions, the Administrative Trustees, or any
  one of them, shall execute the Definitive Preferred Securities Certificates in
  accordance with the instructions of the Clearing Agency. Neither the
  Securities Registrar nor the Trustees shall be liable for any delay in
  delivery of such instructions and may conclusively rely on, and shall be
  protected in relying on, such instructions. Upon the issuance of Definitive
  Preferred Securities Certificates, the Trustees shall recognize the Holders of
  the Definitive Preferred Securities Certificates as Securityholders. The
  Definitive Preferred Securities Certificates shall be printed, lithographed or
  engraved or may be produced in any other manner as is reasonably acceptable to
  the Administrative Trustees, as evidenced by the execution thereof by the
  Administrative Trustees or any one of them.

  SECTION 514.  Rights of Securityholders.
                ------------------------- 

            (a)  The legal title to the Trust Property is vested exclusively in
  the Property Trustee (in its capacity as such) in accordance with Section 209,
  and the Securityholders shall not have any right or title therein other than
  the undivided beneficial interest in the assets of the Trust conferred by
  their Trust Securities and they shall have no right to call for any partition
  or division of property, profits or rights of the Trust except as described
  below.  The Trust Securities shall be personal property giving only the rights
  specifically set forth therein and in this Trust Agreement.  The Trust
  Securities shall have no preemptive or similar rights and when issued and
  delivered to Securityholders against payment of the purchase price therefor
  will be fully paid and nonassessable by the Trust.  The Holders of the Trust
  Securities, in their capacities as such, shall be entitled to the same
  limitation of personal liability extended to stockholders of private
  corporations for profit organized under the General Corporation Law of the
  State of Delaware.

            (b)  For so long as any Preferred Securities remain Outstanding, if,
  upon a Debenture Event of Default, the Debenture Trustee fails or the holders
  of not less than 25% in principal amount of the outstanding Debentures fail to
  declare the principal of all of the Debentures to be immediately due and
  payable, the Holders of at least 25% in

                                      33 


<PAGE>
 
  Liquidation Amount of the Preferred Securities then Outstanding shall have
  such right by a notice in writing to the Depositor and the Debenture Trustee;
  and upon any such declaration such principal amount of and the accrued
  interest on all of the Debentures shall become immediately due and payable,
  provided that the payment of principal and interest on such Debentures shall
  remain subordinated to the extent provided in the Indenture.

            (c)  For so long as any Preferred Securities remain Outstanding, to
  the fullest extent permitted by law and subject to the terms of this Trust
  Agreement, if, upon a Debenture Event of Default specified in Section 501(1)
  or 501(2) of the Indenture, any Holder of Preferred Securities shall have the
  right to directly institute a proceeding for enforcement of payment to such
  Holder of the principal amount of or interest on the Debentures having a
  principal amount equal to the Liquidation Amount of the Preferred Securities
  of such Holder (a "Direct Action").  In connection with such Direct Action,
  the rights of the Holders of the Common Securities will be subrogated to the
  rights of any Holder of the Preferred Securities to the extent of any payment
  made by the Depositor to such Holder of Preferred Securities in such Direct
  Action.  Except as set forth in this Section 514(c), the Holders of Preferred
  Securities will not be able to exercise directly any other remedy available to
  the holders of the Debentures or assert directly any other rights in respect
  of the Debentures.

                                  ARTICLE VI

                   Acts of Securityholders; Meetings; Voting
                   -----------------------------------------

  SECTION 601.   Limitations on Voting Rights
                 ----------------------------

            (a)  Except as provided in this Section, in Sections 810 and
     1002 and in the Indenture and as otherwise required by law, no Holder of
     Preferred Securities shall have any right to vote or in any manner
     otherwise control the administration, operation and management of the Trust
     or the obligations of the parties hereto, nor shall anything herein set
     forth, or contained in the terms of the Trust Securities Certificates, be
     construed so as to constitute the Securityholders from time to time as
     partners or members of an association.

            (b)  So long as any Debentures are held by the Property Trustee,
     the Trustees shall not (i) direct the time, method and place of conducting
     any proceeding for any remedy available to the Debenture Trustee, or
     executing any trust or power conferred on the Debenture Trustee with
     respect to such Debentures, (ii) waive any past default

                                      34 


<PAGE>
 
     which is waiveable under Section 513 of the Indenture, (iii) exercise any
     right to rescind or annul a declaration that the principal of all the
     Debentures shall be due and payable or (iv) consent to any amendment,
     modification or termination of the Indenture or the Debentures, where such
     consent shall be required, without, in each case, obtaining the prior
     approval of the Holders of at least a majority in Liquidation Amount of all
     Outstanding Preferred Securities; provided, however, that where a consent
                                       --------  -------  
     under the Indenture would require the consent of each Holder of Debentures
     affected thereby, no such consent shall be given by the Property Trustee
     without the prior written consent of each Holder of Preferred Securities.
     The Trustees shall not revoke any action previously authorized or approved
     by a vote of the Holders of Preferred Securities, except by a subsequent
     vote of the Holders of Preferred Securities. The Property Trustee shall
     notify all Holders of the Preferred Securities of any notice of default
     received from the Debenture Trustee with respect to the Debentures. In
     addition to obtaining the foregoing approvals of the Holders of the
     Preferred Securities, prior to taking any of the foregoing actions, the
     Trustees shall, at the expense of the Depositor, obtain an Opinion of
     Counsel experienced in such matters to the effect that the Trust will not
     be classified as an association taxable as a corporation for United States
     federal income tax purposes on account of such action.

            (c)  If any proposed amendment to the Trust Agreement provides
     for, or the Trustees otherwise propose to effect, (i) any action that would
     adversely affect in any material respect the powers, preferences or special
     rights of the Preferred Securities, whether by way of amendment to the
     Trust Agreement or otherwise, or (ii) the dissolution, winding-up or
     termination of the Trust, other than pursuant to the terms of this Trust
     Agreement, then the Holders of Outstanding Preferred Securities as a class
     will be entitled to vote on such amendment or proposal and such amendment
     or proposal shall not be effective except with the approval of the Holders
     of at least a majority in Liquidation Amount of the Outstanding Preferred
     Securities.  No amendment to this Trust Agreement may be made if, as a
     result of such amendment, the Trust would be classified as an association
     taxable as a corporation for United States federal income tax purposes.

  SECTION 602.   Notice of Meetings.
                 ------------------

            Notice of all meetings of the Preferred Securityholders, stating the
  time, place and purpose of the meeting, shall be given by the Property Trustee
  pursuant to Section 1008 to each Preferred Securityholder of record, at his
  registered address, at least 15 days and not more than 90 days before the
  meeting.  At any such meeting, any business properly before the meeting may be
  so considered whether or not stated in the notice of the meeting.  Any
  adjourned meeting may be held as adjourned without further notice.

  SECTION 603.   Meetings of Preferred Securityholders.
                 -------------------------------------

            No annual meeting of Securityholders is required to be held.  The
  Administrative Trustees, however, shall call a meeting of Securityholders to
  vote on any matter upon the written request of the Preferred Securityholders
  of record of 25% of the Preferred Securities (based upon their Liquidation
  Amount) and the Administrative Trustees or the Property Trustee may, at any
  time in their discretion, call a meeting of Preferred Securityholders to vote
  on any matters as to which Preferred Securityholders are entitled to vote.

            Preferred Securityholders of record of 50% of the Outstanding
  Preferred Securities (based upon their Liquidation Amount), present in person
  or by proxy, shall constitute a quorum at any meeting of Securityholders.

            If a quorum is present at a meeting, an affirmative vote by the
  Preferred Securityholders of record present, in person or by proxy, holding
  more than a majority of the Preferred Securities (based upon their Liquidation
  Amount) held by the Preferred Securityholders of record present, either in
  person or by proxy, at such meeting shall constitute the action of the
  Securityholders, unless this Trust Agreement requires a greater number of
  affirmative votes.

  SECTION 604.   Voting Rights
                 -------------

            Securityholders shall be entitled to one vote for each $25 of
  Liquidation Amount represented by their Trust Securities in respect of any
  matter as to which such Securityholders are entitled to vote.

                                      36


<PAGE>
 
  SECTION 605.   Proxies, etc.
                 -------------      

            At any meeting of Securityholders, any Securityholder entitled to
  vote thereat may vote by proxy, provided that no proxy shall be voted at any
  meeting unless it shall have been placed on file with the Administrative
  Trustees, or with such other officer or agent of the Trust as the
  Administrative Trustees may direct, for verification prior to the time at
  which such vote shall be taken.  Pursuant to a resolution of the Property
  Trustee, proxies may be solicited in the name of the Property Trustee or one
  or more officers of the Property Trustee.  Only Securityholders of record
  shall be entitled to vote.  When Trust Securities are held jointly by several
  persons, any one of them may vote at any meeting in person or by proxy in
  respect of such Trust Securities, but if more than one of them shall be
  present at such meeting in person or by proxy, and such joint owners or their
  proxies so present disagree as to any vote to be cast, such vote shall not be
  received in respect of such Trust Securities.  A proxy purporting to be
  executed by or on behalf of a Securityholder shall be deemed valid unless
  challenged at or prior to its exercise, and the burden of proving invalidity
  shall rest on the challenger.  No proxy shall be valid more than three years
  after its date of execution.

  SECTION 606.    Securityholder Action by Written Consent.
                  ----------------------------------------

            Any action which may be taken by Securityholders at a meeting may be
  taken without a meeting if Securityholders holding more than a majority of all
  Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
  vote in respect of such action (or such larger proportion thereof as shall be
  required by any express provision of this Trust Agreement) shall consent to
  the action in writing.

  SECTION 607.    Record Date for Voting and Other Purposes
                  -----------------------------------------

            For the purposes of determining the Securityholders who are entitled
  to notice of and to vote at any meeting or by written consent, or to
  participate in any distribution on the Trust Securities in respect of which a
  record date is not otherwise provided for in this Trust Agreement, or for the
  purpose of any other action, the Administrative Trustees may from time to time
  fix a date, not more than 90 days prior to the date of any meeting of
  Securityholders or the payment of a distribution or other action, as the case
  may be, as a record date for the determination of the identity of the
  Securityholders of record for such purposes.

                                      37


<PAGE>
 
  SECTION 608.    Acts of Securityholders
                  -----------------------

            Any request, demand, authorization, direction, notice, consent,
  waiver or other action provided or permitted by this Trust Agreement to be
  given, made or taken by Securityholders or Owners may be embodied in and
  evidenced by one or more instruments of substantially similar tenor signed by
  such Securityholders or Owners in person or by an agent duly appointed in
  writing; and, except as otherwise expressly provided herein, such action shall
  become effective when such instrument or instruments are delivered to an
  Administrative Trustee.  Such instrument or instruments (and the action
  embodied therein and evidenced thereby) are herein sometimes referred to as
  the "Act" of the Securityholders or Owners signing such instrument or
  instruments.  Proof of execution of any such instrument or of a writing
  appointing any such agent shall be sufficient for any purpose of this Trust
  Agreement and (subject to Section 801) conclusive in favor of the Trustees, if
  made in the manner provided in this Section.

            The fact and date of the execution by any Person of any such
  instrument or writing may be proved by the affidavit of a witness of such
  execution or by a certificate of a notary public or other officer authorized
  by law to take acknowledgments of deeds, certifying that the individual
  signing such instrument or writing acknowledged to him the execution thereof.
  Where such execution is by a signer acting in a capacity other than his
  individual capacity, such certificate or affidavit shall also constitute
  sufficient proof of his authority.  The fact and date of the execution of any
  such instrument or writing, or the authority of the Person executing the same,
  may also be proved in any other manner which any Trustee receiving the same
  deems sufficient.

            The ownership of Preferred Securities shall be proved by the
  Securities Register.

            Any request, demand, authorization, direction, notice, consent,
  waiver or other Act of the Securityholder of any Trust Security shall bind
  every future Securityholder of the same Trust Security and the Securityholder
  of every Trust Security issued upon the registration of transfer thereof or in
  exchange therefor or in lieu thereof in respect of anything done, omitted or
  suffered to be done by the Trustees or the Trust in reliance thereon, whether
  or not notation of such action is made upon such Trust Security.

                                      38


<PAGE>
 
            Without limiting the foregoing, a Securityholder entitled hereunder
  to take any action hereunder with regard to any particular Trust Security may
  do so with regard to all or any part of the Liquidation Amount of such Trust
  Security or by one or more duly appointed agents each of which may do so
  pursuant to such appointment with regard to all or any part of such
  liquidation amount.

            If any dispute shall arise between the Securityholders and the
  Administrative Trustees or among such Securityholders or Trustees with respect
  to the authenticity, validity or binding nature of any request, demand,
  authorization, direction, consent, waiver or other Act of such Securityholder
  or Trustee under this Article VI, then the determination of such matter by the
  Property Trustee shall be conclusive with respect to such matter.

            A Securityholder may institute a legal proceeding directly against
  the Depositor under the Guarantee to enforce its rights under the Guarantee
  without first instituting a legal proceeding against the Guarantee Trustee (as
  defined in the Guarantee), the Trust or any person or entity.

  SECTION 609.    Inspection of Records
                  ---------------------

            Upon reasonable notice to the Administrative Trustees and the
  Property Trustee, the records of the Trust shall be open to inspection by
  Securityholders during normal business hours for any purpose reasonably
  related to such Securityholder's interest as a Securityholder.

                  Trustee and the Delaware Trustee.
                  ---------------------------------


            The Bank, the Property Trustee and the Delaware Trustee, each
  severally on behalf of and as to itself, hereby represents and warrants for
  the benefit of the Depositor and the Securityholders that:

            (a)  the Bank is a Delaware banking corporation duly organized,
       validly existing and in good standing under the laws of the State of
       Delaware;

            (b)  the Bank has full corporate power, authority and legal
       right to execute, deliver and perform its

                                      39 


<PAGE>
 
       obligations under this Trust Agreement and has taken all necessary action
       to authorize the execution, delivery and performance by it of this Trust
       Agreement;

            (c)  this Trust Agreement has been duly authorized, executed and
       delivered by the Bank and constitutes the valid and legally binding
       agreement of the Bank enforceable against it in accordance with its
       terms, subject to bankruptcy, insolvency, fraudulent transfer,
       reorganization, moratorium and similar laws of general applicability
       relating to or affecting creditors' rights and to general equity
       principles;

            (d)  the execution, delivery and performance by the Bank of this
       Trust Agreement has been duly authorized by all necessary corporate or
       other action on the part of the Bank, the Property Trustee and the
       Delaware Trustee and does not require any approval of stockholders of the
       Bank and such execution, delivery and performance will not (i) violate
       the Bank's charter or by-laws, (ii) violate any provision of, or
       constitute, with or without notice or lapse of time, a default under, or
       result in the creation or imposition of, any Lien on any properties
       included in the Trust Property pursuant to the provisions of, any
       indenture, mortgage, credit agreement, license or other agreement or
       instrument to which the Property Trustee, the Bank or the Delaware
       Trustee is a party or by which it is bound, or (iii) violate any law,
       governmental rule or regulation of the United States or the State of
       Delaware, as the case may be, governing the banking or trust powers of
       the Bank, the Property Trustee or the Delaware Trustee (as appropriate in
       context) or any order, judgment or decree applicable to the Property
       Trustee, the Bank or the Delaware Trustee;

            (e)  neither the authorization, execution or delivery by the
       Bank of this Trust Agreement nor the consummation of any of the
       transactions by the Bank, the Property Trustee or the Delaware Trustee
       (as appropriate in context) contemplated herein or therein requires the
       consent or approval of, the giving of notice to, the registration with or
       the taking of any other action with respect to any governmental authority
       or agency under any existing federal law governing the banking or trust
       powers of the Bank, the Property Trustee or the Delaware Trustee, as the
       case may be, under the laws of the United States or the State of
       Delaware;

                                      40


<PAGE>
 
            (f)  there are no proceedings pending or, to the best of each of
       the Bank's, the Property Trustee's and the Delaware Trustee's knowledge,
       threatened against or affecting the Bank, the Property Trustee or the
       Delaware Trustee in any court or before any governmental authority,
       agency or arbitration board or tribunal which, individually or in the
       aggregate, would materially and adversely affect the Trust or would
       question the right, power and authority of the Bank, the Property Trustee
       or the Delaware Trustee, as the case may be, to enter into or perform its
       obligations as one of the Trustees under this Trust Agreement.

  SECTION 702.   Representations and Warranties of Depositor.
                 ------------------------------------------- 


            The Depositor hereby represents and warrants for the benefit of the
  Securityholders that:

            (a) the Trust Securities Certificates issued at each Time of
       Delivery on behalf of the Trust have been duly authorized and will have
       been duly and validly executed, issued and delivered by the Trustees
       pursuant to the terms and provisions of, and in accordance with the
       requirements of, this Trust Agreement and the Securityholders will be, as
       of such date, entitled to the benefits of this Trust Agreement; and

            (b) there are no taxes, fees or other governmental charges payable
       by the Trust (or the Trustees on behalf of the Trust) under the laws of
       the State of Delaware or any political subdivision thereof in connection
       with the execution, delivery and performance by the Bank, the Property
       Trustee or the Delaware Trustee, as the case may be, of this Trust
       Agreement.

                                 ARTICLE VIII
                                 ------------
                                 The Trustees
                                 ------------

  SECTION 801.   Certain Duties and Responsibilities
                 -----------------------------------

            (a)  The duties and responsibilities of the Trustees shall be as
     provided by this Trust Agreement and, in the case of the Property Trustee,
     by the Trust Indenture Act.  Notwithstanding the foregoing, no provision of
     this Trust Agreement shall require the Trustees to expend or risk their own
     funds or otherwise incur any financial liability in the performance of any
     of their duties hereunder, or in the exercise of any of their rights or
     powers, if they shall have reasonable grounds for believing that repayment
     of such funds or adequate indemnity against such risk or liability

                                      41 


<PAGE>
 
     is not reasonably assured to it. Whether or not therein expressly so
     provided, every provision of this Trust Agreement relating to the conduct
     or affecting the liability of or affording protection to the Trustees shall
     be subject to the provisions of this Section. Nothing in this Trust
     Agreement shall be construed to release the Property Trustee from liability
     for its own negligent action, its own negligent failure to act, or its own
     willful misconduct. To the extent that, at law or in equity, an
     Administrative Trustee has duties (including fiduciary duties) and
     liabilities relating thereto to the Trust or to the Securityholders, such
     Administrative Trustee shall not be liable to the Trust or to any
     Securityholder for such Trustee's good faith reliance on the provisions of
     this Trust Agreement. The provisions of this Trust Agreement, to the extent
     that they restrict the duties and liabilities of the Administrative
     Trustees otherwise existing at law or in equity, are agreed by the
     Depositor and the Securityholders to replace such other duties and
     liabilities of the Administrative Trustees.

            (b)   All payments made by the Property Trustee or a Paying Agent
     in respect of the Trust Securities shall be made only from the revenue and
     proceeds from the Trust Property and only to the extent that there shall be
     sufficient revenue or proceeds from the Trust Property to enable the
     Property Trustee or a Paying Agent to make payments in accordance with the
     terms hereof.  Each Securityholder, by its acceptance of a Trust Security,
     agrees that it will look solely to the revenue and proceeds from the Trust
     Property to the extent legally available for distribution to it as herein
     provided and that the Trustees are not personally liable to it for any
     amount distributable in respect of any Trust Security or for any other
     liability in respect of any Trust Security.  This Section 801(b) does not
     limit the liability of the Trustees expressly set forth elsewhere in this
     Trust Agreement or, in the case of the Property Trustee, in the Trust
     Indenture Act.

            (c)  No provision of this Trust Agreement shall be construed to
     relieve the Property Trustee from liability for its own negligent action,
     its own negligent failure to act, or its own willful misconduct, except
     that:

            (i)  the Property Trustee shall not be liable for any error      
       of judgment made in good faith by an authorized officer of the Property
       Trustee, unless it shall be proved that the Property Trustee was
       negligent in ascertaining the pertinent facts;

                                      42


<PAGE>
 
            (ii)  the Property Trustee shall not be liable with respect
       to any action taken or omitted to be taken by it in good faith in
       accordance with the direction of the Holders of not less than a majority
       in Liquidation Amount of the Trust Securities relating to the time,
       method and place of conducting any proceeding for any remedy available to
       the Property Trustee, or exercising any trust or power conferred upon the
       Property Trustee under this Trust Agreement;

            (iii)  the Property Trustee's sole duty with respect to the
       custody, safe keeping and physical preservation of the Debentures and the
       Payment Account shall be to deal with such Property in a similar manner
       as the Property Trustee deals with similar property for its own account,
       subject to the protections and limitations on liability afforded to the
       Property Trustee under this Trust Agreement and the Trust Indenture Act;

            (iv)  the Property Trustee shall not be liable for any
       interest on any money received by it except as it may otherwise agree
       with the Depositor, and money held by the Property Trustee need not be
       segregated from other funds held by it except in relation to the Payment
       Account maintained by the Property Trustee pursuant to Section 301 and
       except to the extent otherwise required by law; and

            (v)  the Property Trustee shall not be responsible for
       monitoring the compliance by the Administrative Trustees or the Depositor
       with their respective duties under this Trust Agreement, nor shall the
       Property Trustee be liable for the default or misconduct of the
       Administrative Trustees or the Depositor.

  SECTION 802.   Certain Notices.
                 ---------------- 

            Within five Business Days after the occurrence of any Event of
  Default actually known to the Property Trustee, the Property Trustee shall
  transmit, in the manner and to the extent provided in Section 1008, notice of
  such Event of Default to the Securityholders, the Administrative Trustees and
  the Depositor, unless such Event of Default shall have been cured or waived.

            Within five Business Days after the receipt of notice of the
  Depositor's exercise of its right to defer the payment of interest on the
  Debentures pursuant to the Indenture, the Administrative Trustee shall
  transmit, in the manner and to the extent provided in Section 1008, notice of

                                      43


<PAGE>
 
  such exercise to the Securityholders and the Property Trustee, unless such
  exercise shall have been revoked.

  SECTION 803.   Certain Rights of Property Trustee.
                 -----------------------------------

            Subject to the provisions of Section 801:

            (a)  the Property Trustee may rely and shall be protected in
       acting or refraining from acting in good faith upon any resolution,
       Opinion of Counsel, certificate, written representation of a Holder or
       transferee, certificate of auditors or any other certificate, statement,
       instrument, opinion, report, notice, request, consent, order, appraisal,
       bond, debenture, note, other evidence of indebtedness or other paper or
       document believed by it to be genuine and to have been signed or
       presented by the proper party or parties;

            (b)  if (i) in performing its duties under this Trust Agreement
       the Property Trustee is required to decide between alternative courses of
       action or (ii) in construing any of the provisions of this Trust
       Agreement the Property Trustee finds the same ambiguous or inconsistent
       with any other provisions contained herein or (iii) the Property Trustee
       is unsure of the application of any provision of this Trust Agreement,
       then, except as to any matter as to which the Preferred Securityholders

            (f)  the Property Trustee may consult with counsel (which
       counsel may be counsel to the Depositor or any of its Affiliates, and may
       include any of its employees) and the advice of such counsel shall be
       full and complete authorization and protection in respect of any action
       taken, suffered or omitted by it hereunder in good faith and in reliance
       thereon and in accordance with such advice; the Property Trustee shall
       have the right at any time to seek instructions concerning the

                 -------------------

  individual or any other capacity, may become the owner or pledgee of Trust

  SECTION 806.   Compensation; Indemnity; Fees.
                 ----------------------------- 


            The Depositor agrees:

            (a)  to pay to the Trustees from time to time reasonable

  SECTION 807.   Corporate Property Trustee Required; Eligibility of
                 ---------------------------------------------------
                 Trustees
                 --------

            (a)  There shall at all times be a Property Trustee hereunder
     with respect to the Trust Securities.  The Property Trustee shall be a
     Person that is eligible pursuant to the Trust Indenture Act to act as such
     and has a combined capital and surplus of at least $50,000,000.  If any
     such Person publishes reports of condition at least annually, pursuant to
     law or to the requirements of its supervising or examining authority, then
     for the purposes of this Section, the combined capital and surplus of such
     Person shall be deemed to be its combined capital and surplus as set forth
     in its most recent report of condition so published.  If at any time the
     Property Trustee with respect to the Trust Securities shall cease to be
     eligible in accordance with the provisions of this Section, it shall resign
     immediately in the manner and with the effect hereinafter specified in this
     Article.

            (b)  There shall at all times be one or more Administrative
     Trustees hereunder with respect to the Trust Securities.  Each
     Administrative Trustee shall be either a natural person who is at least 21
     years of age or a legal entity that shall act through one or more persons
     authorized to bind that entity.

            (c)  There shall at all times be a Delaware Trustee with
     respect to the Trust Securities.  The Delaware Trustee shall either be (i)
     a natural person who is at least 21 years of age and a resident of the
     State of Delaware or (ii) a legal entity with its principal place of
     business in the State of Delaware and that otherwise meets the requirements
     of applicable Delaware law that shall act through one or more persons
     authorized to bind such entity.

  SECTION 808.   Conflicting Interests.
                 ---------------------

            If the Property Trustee has or shall acquire a conflicting interest
  within the meaning of the Trust Indenture Act, the Property Trustee shall
  either eliminate such interest or resign, to the extent and in the manner
  provided by, and subject to the provisions of, the Trust Indenture Act and
  this Trust Agreement.

  SECTION 809.   Co-Trustees and Separate Trustee.
                 -------------------------------- 

            Unless an Event of Default shall have occurred and be continuing, at
  any time or times, for the purpose of meeting the legal requirements of the
  Trust Indenture Act or of any jurisdiction in which any part of the Trust
  Property 

                                      48


<PAGE>
 
  may at the time be located, the Depositor and the Administrative Trustees, 
  by agreed action of the majority of such Trustees, shall have power to 
  appoint, and upon the written request of the Administrative Trustees, the
  Depositor shall for such purpose join with the Administrative Trustees in the
  execution, delivery and performance of all instruments and agreements
  necessary or proper to appoint, one or more Persons approved by the Property
  Trustee either to act as co-trustee, jointly with the Property Trustee, of all
  or any part of such Trust Property, or to the extent required by law to act as
  separate trustee of any such property, in either case with such powers as may
  be provided in the instrument of appointment, and to vest in such Person or
  Persons in the capacity aforesaid, any property, title, right or power deemed
  necessary or desirable, subject to the other provisions of this Section.  If
  the Depositor does not join in such appointment within 15 days after the
  receipt by it of a request so to do, or in case a Debenture Event of Default
  has occurred and is continuing, the Property Trustee alone shall have power to
  make such appointment.  Any co-trustee or separate trustee appointed pursuant
  to this Section shall either be (i) a natural person who is at least 21 years
  of age and a resident of the United States or (ii) a legal entity with its
  principal place of business in the United States that shall act through one or
  more persons authorized to bind such entity.

            Should any written instrument from the Depositor be required by any
  co-trustee or separate trustee so appointed for more fully confirming to such
  co-trustee or separate trustee such property, title, right, or power, any and
  all such instruments shall, on request, be executed, acknowledged and
  delivered by the Depositor.

            Every co-trustee or separate trustee shall, to the extent permitted
  by law, but to such extent only, be appointed subject to the following terms,
  namely:

            (a)  The Trust Securities shall be executed and delivered and
       all rights, powers, duties and obligations hereunder in respect of the
       custody of securities, cash and other personal property held by, or
       required to be deposited or pledged with, the Trustees specified
       hereunder, shall be exercised, solely by such Trustees and not by such
       co-trustee or separate trustee.

            (b)  The rights, powers, duties and obligations hereby
       conferred or imposed upon the Property Trustee in respect of any property
       covered by such appointment

                                      49


<PAGE>
 
       shall be conferred or imposed upon and exercised or performed by the
       Property Trustee or by the Property Trustee and such co-trustee or
       separate trustee jointly, as shall be provided in the instrument
       appointing such co-trustee or separate trustee, except to the extent that
       under any law of any jurisdiction in which any particular act is to be
       performed, the Property Trustee shall be incompetent or unqualified to
       perform such act, in which event such rights, powers, duties and
       obligations shall be exercised and performed by such co-trustee or
       separate trustee.

            (c)  The Property Trustee at any time, by an instrument in
       writing executed by it, with the written concurrence of the Depositor,
       may accept the resignation of or remove any co-trustee or separate
       trustee appointed under this Section, and, in case a Debenture Event of
       Default has occurred and is continuing, the Property Trustee shall have
       power to accept the resignation of, or remove, any such co-trustee or
       separate trustee without the concurrence of the Depositor.  Upon the
       written request of the Property Trustee, the Depositor shall join with
       the Property Trustee in the execution, delivery and performance of all
       instruments and agreements necessary or proper to effectuate such
       resignation or removal.  A successor to any co-trustee or separate
       trustee so resigned or removed may be appointed in the manner provided in
       this Section.

            (d)  No co-trustee or separate trustee hereunder shall be
       personally liable by reason of any act or omission of the Property
       Trustee or any other trustee hereunder.

            (e)  The Property Trustee shall not be liable by reason of any
       act of a co-trustee or separate trustee.

            (f)  Any Act of Holders delivered to the Property Trustee shall
       be deemed to have been delivered to each such co-trustee and separate
       trustee.

  SECTION 810.  Resignation and Removal; Appointment of Successor.
                ------------------------------------------------- 

            No resignation or removal of any Trustee (the "Relevant Trustee")
  and no appointment of a successor Trustee pursuant to this Article shall
  become effective until the acceptance of appointment by the successor Trustee
  in accordance with the applicable requirements of Section 811.

                                      50


<PAGE>
 
            Subject to the immediately preceding paragraph, the Relevant Trustee
  may resign at any time with respect to the Trust Securities by giving written
  notice thereof to the Securityholders.  If the instrument of acceptance by the
  successor Trustee required by Section 811 shall not have been delivered to the
  Relevant Trustee within 30 days after the giving of such notice of
  resignation, the Relevant Trustee may petition, at the expense of the Company,
  any court of competent jurisdiction for the appointment of a successor
  Relevant Trustee with respect to the Trust Securities.

            Unless a Debenture Event of Default shall have occurred and be
  continuing, any Trustee may be removed at any time by Act of the Common
  Securityholder.  If a Debenture Event of Default shall have occurred and be
  continuing, the Property Trustee or the Delaware Trustee, or both of them, may
  be removed at such time by Act of the Holders of a majority in Liquidation
  Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
  individual capacity and on behalf of the Trust).  An Administrative Trustee
  may be removed by the Common Securityholder at any time.

            If any Trustee shall resign, be removed or become incapable of
  acting as Trustee, or if a vacancy shall occur in the office of any Trustee
  for any cause, at a time when no Debenture Event of Default shall have
  occurred and be continuing, the Common Securityholder, by Act of the Common
  Securityholder delivered to the retiring Trustee, shall promptly appoint a
  successor Trustee or Trustees with respect to the Trust Securities and the
  Trust, and the successor Trustee shall comply with the applicable requirements
  of Section 811.  If the Property Trustee or the Delaware Trustee shall resign,
  be removed or become incapable of continuing to act as the Property Trustee or
  the Delaware Trustee, as the case may be, at a time when a Debenture Event of
  Default shall have occurred and be continuing, the Preferred Securityholders,
  by Act of the Securityholders of a majority in Liquidation Amount of the
  Preferred Securities then Outstanding delivered to the retiring Relevant
  Trustee, shall promptly appoint a successor Relevant Trustee or Trustees with
  respect to the Trust Securities and the Trust, and such successor Trustee
  shall comply with the applicable requirements of Section 811.  If an
  Administrative Trustee shall resign, be removed or become incapable of acting
  as Administrative Trustee, at a time when a Debenture Event of Default shall
  have occurred and be continuing, the Common Securityholder, by Act of the
  Common Securityholder delivered to the Administrative Trustee, shall promptly
  appoint a successor Administrative

                                      51


<PAGE>
 
  Trustee or Administrative Trustees with respect to the Trust Securities and
  the Trust, and such successor Administrative Trustee or Administrative
  Trustees shall comply with the applicable requirements of Section 811. If no
  successor Relevant Trustee with respect to the Trust Securities shall have
  been so appointed by the Common Securityholder or the Preferred
  Securityholders and accepted appointment in the manner required by Section
  811, any Securityholder who has been a Securityholder of Trust Securities for
  at least six months may, on behalf of himself and all others similarly
  situated, petition any court of competent jurisdiction for the appointment of
  a successor Relevant Trustee with respect to the Trust Securities.

            The Property Trustee shall give notice of each resignation and each
  removal of a Trustee and each appointment of a successor Trustee to all
  Securityholders in the manner provided in Section 1008 and shall give notice
  to the Depositor.  Each notice shall include the name of the successor
  Relevant Trustee and the address of its Corporate Trust Office if it is the
  Property Trustee.

            Notwithstanding the foregoing or any other provision of this Trust
  Agreement, in the event any Administrative Trustee or a Delaware Trustee who
  is a natural person dies or becomes, in the opinion of the Depositor,
  incompetent or incapacitated, the vacancy created by such death, incompetence
  or incapacity may be filled by (a) the unanimous act of remaining
  Administrative Trustees if there are at least two of them or (b) otherwise by
  the Depositor (with the successor in each case being a Person who satisfies
  the eligibility requirement for Administrative Trustees set forth in Section
  807).

  SECTION 811.  Acceptance of Appointment by Successor.
                -------------------------------------- 

            In case of the appointment hereunder of a successor Trustee such
  successor Trustee so appointed shall execute, acknowledge and deliver to the
  Trust and to the retiring Trustee an instrument accepting such appointment,
  and thereupon the resignation or removal of the retiring Trustee shall become
  effective and such successor Trustee, without any further act, deed or
  conveyance, shall become vested with all the rights, powers, trusts and duties
  of the retiring Trustee; but, on the request of the Depositor or the successor
  Trustee, such retiring Trustee shall, upon payment of its charges, execute and
  deliver an instrument transferring to such successor Trustee all the rights,
  powers and trusts of the retiring Trustee and if the Property Trustee is the
  resigning Trustee shall duly assign,

                                      52


<PAGE>
 
  transfer and deliver to the successor Trustee all property and money held by
  such retiring Property Trustee hereunder.

            In case of the appointment hereunder of a successor Relevant Trustee
  with respect to the Trust Securities and the Trust, the retiring Relevant
  Trustee and each successor Relevant Trustee with respect to the Trust
  Securities shall execute and deliver an amendment hereto wherein each
  successor Relevant Trustee shall accept such appointment and which (a) shall
  contain such provisions as shall be necessary or desirable to transfer and
  confirm to, and to vest in, each successor Relevant Trustee all the rights,
  powers, trusts and duties of the retiring Relevant Trustee with respect to the
  Trust Securities and the Trust and (b) shall add to or change any of the
  provisions of this Trust Agreement as shall be necessary to provide for or
  facilitate the administration of the trusts hereunder by more than one
  Relevant Trustee, it being understood that nothing herein or in such amendment
  shall constitute such Relevant Trustees co-trustees of the same trust and that
  each such Relevant Trustee shall be trustee of a trust or trusts hereunder
  separate and apart from any trust or trusts hereunder administered by any
  other such Relevant Trustee and upon the execution and delivery of such
  amendment the resignation or removal of the retiring Relevant Trustee shall
  become effective to the extent provided therein and each such successor
  Relevant Trustee, without any further act, deed or conveyance, shall become
  vested with all the rights, powers, trusts and duties of the retiring Relevant
  Trustee with respect to the Trust Securities and the Trust; but, on request of
  the Trust or any successor Relevant Trustee such retiring Relevant Trustee
  shall duly assign, transfer and deliver to such successor Relevant Trustee all
  Trust Property, all proceeds thereof and money held by such retiring Relevant
  Trustee hereunder with respect to the Trust Securities and the Trust.

            Upon request of any such successor Relevant Trustee, the Trust shall
  execute any and all instruments for more fully and certainly vesting in and
  confirming to such successor Relevant Trustee all such rights, powers and
  trusts referred to in the first or second preceding paragraph, as the case may
  be.

            No successor Relevant Trustee shall accept its appointment unless at
  the time of such acceptance such successor Relevant Trustee shall be qualified
  and eligible under this Article.

                                      53

  SECTION 812.  Merger, Conversion, Consolidation or Succession to Business.
                ----------------------------------------------------------- 

            Any corporation into which the Property Trustee or the Delaware
  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 such Relevant Trustee shall be a party, or any corporation succeeding to
  all or substantially all the corporate trust business of such Relevant
  Trustee, shall be the successor of such Relevant Trustee hereunder, provided
  such corporation shall be otherwise qualified and eligible under this Article,
  without the execution or filing of any paper or any further act on the part of
  any of the parties hereto.

  SECTION 813.  Preferential Collection of Claims Against Depositor or Trust.
                ------------------------------------------------------------ 

            If and when the Property Trustee or the Delaware Trustee shall be or
  become a creditor of the Depositor or the Trust (or any other obligor upon the
  Debentures or the Trust Securities), the Property Trustee or the Delaware
  Trustee, as the case may be, shall be subject to and shall take all actions
  necessary in order to comply with the provisions of the Trust Indenture Act
  regarding the collection of claims against the Depositor or Trust (or any such
  other obligor).

  SECTION 814.  Reports by Property Trustee.
                --------------------------- 

            (a)  Not later than July 15 of each year commencing with July 15,
  1997, the Property Trustee shall transmit to all Securityholders in accordance
  with Section 1008, and to the Depositor, a brief report dated as of such
  December 31 with respect to:

            (i)  its eligibility under Section 807 or, in lieu thereof,
       if to the best of its knowledge it has continued to be eligible under
       said Section, a written statement to such effect;

            (ii)  a statement that the Property Trustee has complied with
       all of its obligations under this Trust Agreement during the twelve-month
       period (or, in the case of the initial report, the period since the
       Closing Date) ending with such December 31 or, if the Property Trustee
       has not complied in any material respect with such obligations, a
        description of such noncompliance; and

                                      54


<PAGE>
 
          (iii) any change in the property and funds in its possession
       as Property Trustee since the date of its last report and any action
       taken by the Property Trustee in the performance of its duties hereunder
       which it has not previously reported and which in its opinion materially
       affects the Trust Securities.


            (b) In addition, the Property Trustee shall transmit to
  Securityholders such reports concerning the Property Trustee and its actions
  under this Trust Agreement as may be required pursuant to the Trust Indenture
  Act at the times and in the manner provided pursuant thereto.

  Securities are listed or traded, with the Commission and with the Depositor.

            (b)  If a Trustee ceases to hold office for any reason and the
  number of Administrative Trustees is not reduced pursuant to Section 817(a),
  or if the number of Trustees is increased pursuant to Section 817(a), a

  accordance with Section 810.

  Administrative Trustees in office, regardless of their number (and
  notwithstanding any other provision of this Agreement), shall have all the

  or the names of the Administrative Trustees or otherwise as the Administrative
  Trustees may deem expedient, to the extent such delegation is not prohibited
  by applicable law or contrary to the provisions of the Trust, as set forth
  herein.

                     -------------------------------------

  SECTION 901.  Termination Upon Expiration Date.
                 ------------------------------- 

            Unless earlier terminated, the Trust shall automatically terminate
  on _________ __, 2051 (the "Expiration Date"), following the distribution of
  the Trust Property in accordance with Section 904.

                                      56


<PAGE>
 
  SECTION 902.  Early Termination.
                ----------------- 

            The first to occur of any of the following events is an "Early
  Termination Event":

            (a)  the occurrence of a Bankruptcy Event in respect of, or the
       dissolution or liquidation of, the Depositor;

            (b)  the written direction to the Property Trustee from the

       Debentures in exchange for the Preferred Securities;

            (c)  the redemption of all of the Preferred Securities in
       connection with the redemption of all of the Debentures; and

            (d)  the entry of an order for dissolution of the Trust by a
       court of competent jurisdiction.

  SECTION 903.  Termination.
                ----------- 

            The respective obligations and responsibilities of the Trustees and
  the Trust created and continued hereby shall terminate upon the latest to
  occur of the following:  (a) the distribution by the Property Trustee to
  Securityholders upon the liquidation of the Trust pursuant to Section 904, or
  upon the redemption of all of the Trust Securities pursuant to Section 402, of
  all amounts required to be distributed hereunder upon the final payment of the
  Trust Securities; (b) the payment of any expenses owed by the Trust; and (c)
  the discharge of all administrative duties of the Administrative Trustees,
  including the performance of any tax reporting obligations with respect to the
  Trust or the Securityholders.

  SECTION 904.  Liquidation.
                ----------- 

            (a)  If an Early Termination Event specified in clause (a), (b)
     or (d) of Section 902 occurs or upon the Expiration Date, the Trust shall
     be liquidated by the Trustees as expeditiously as the Trustees determine to
     be possible by distributing, after satisfaction of liabilities to creditors
     of the Trust as provided by applicable law, to each Securityholder a Like
     Amount of Debentures, subject to Section 904(d).  Notice of liquidation
     shall be given by the Property Trustee by first-class mail, postage
     prepaid, mailed not later than 30 nor more than 60 days prior to the
     Liquidation Date to each Holder of Trust Securities at such

                                      57


<PAGE>
 
     Holder's address appearing in the Securities Register. All notices of
     liquidation shall:

              (i)  state the Liquidation Date;
                   --------------------------

             (ii)  state that from and after the Liquidation Date, the
       Trust Securities will no longer be deemed to be Outstanding and any Trust
       Securities Certificates not surrendered for exchange will be deemed to
       represent a Like Amount of Debentures; and

            (iii)   provide such information with respect to the mechanics by
       which Holders may exchange Trust Securities Certificates for Debentures,
       or if Section 904(d) applies receive a Liquidation Distribution, as the
       Administrative Trustees or the Property Trustee shall deem appropriate.
      
              (b)  Except where Section 902(c) or 904(d) applies, in order to
     effect the liquidation of the Trust and distribution of the Debentures to
     Securityholders, the Property Trustee shall establish a record date for
     such distribution (which shall be not more than 45 days prior to the
     Liquidation Date) and, either itself acting as exchange agent or through
     the appointment of a separate exchange agent, shall establish such
     procedures as it shall deem appropriate to effect the distribution of
     Debentures in exchange for the Outstanding Trust Securities Certificates.

              (c)  Except where Section 902(c) or 904(d) applies, after the
     Liquidation Date, (i) the Trust Securities will no longer be deemed to be
     Outstanding, (ii) certificates representing a Like Amount of Debentures
     will be issued to holders of Trust Securities Certificates, upon surrender
     of such certificates to the Administrative Trustees or their agent for
     exchange, (iii) the Depositor shall use its reasonable efforts to have the
     Debentures listed on the New York Stock Exchange or on such other stock
     exchange, interdealer quotation system or self-regulatory organization as
     the Preferred Securities are then listed or traded, (iv) any Trust
     Securities Certificates not so surrendered for exchange will be deemed to
     represent a Like Amount of Debentures, accruing interest at the rate
     provided for in the Debentures from the last Distribution Date on which a
     Distribution was made on such Trust Securities Certificates until such
     certificates are so surrendered (and until such certificates are so
     surrendered, no payments of interest or principal will be made to holders
     of Trust Securities Certificates with respect to such Debentures), and (v)
     all rights of Securityholders holding Trust Securities will cease, except
     the right of such 

                                      58

     Securityholders to receive Debentures upon surrender of Trust Securities
     Certificates.

            (d)  In the event that, notwithstanding the other provisions of
     this Section 904, whether because of an order for dissolution entered by a
     court of competent jurisdiction or otherwise, distribution of the
     Debentures in the manner provided herein is determined by the Property
     Trustee not to be practical, the Trust Property shall be liquidated, and
     the Trust shall be dissolved, wound-up or terminated, by the Property
     Trustee in such manner as the Property Trustee determines.  In such event,
     on the date of the dissolution, winding-up or other termination of the
     Trust, Securityholders will be entitled to receive out of the assets of the
     Trust available for distribution to Securityholders, after satisfaction of
     liabilities to creditors of the Trust as provided by applicable law, an
     amount equal to the Liquidation Amount per Trust Security plus accumulated
     and unpaid Distributions thereon to the date of payment (such amount being
     the "Liquidation Distribution").  If, upon any such dissolution, winding-up
     or termination, the Liquidation Distribution can be paid only in part
     because the Trust has insufficient assets available to pay in full the
     aggregate Liquidation Distribution, then, subject to the next succeeding
     sentence, the amounts payable by the Trust on the Trust Securities shall be
     paid on a pro rata basis (based upon Liquidation Amounts).  The holder of
     the Common Securities will be entitled to receive Liquidation Distributions
     upon any such dissolution, winding-up or termination pro rata (determined
     as aforesaid) with Holders of Preferred Securities, except that, if a
     Debenture Event of Default has occurred and is continuing, the Preferred
     Securities shall have a priority over the Common Securities.

     SECTION 905.  Mergers, Consolidations, Amalgamations or Replacements of
                   --------------------------------------------------------- 
                   the Trust.  
                   --------- 

            The Trust may not merge with or into, consolidate, amalgamate, or be
  replaced by, or convey, transfer or lease its properties and assets
  substantially as an entirety to any corporation or other body, except pursuant
  to this Section 905.  At the request of the Depositor, with the consent of the
  Administrative Trustees and without the consent of the holders of the
  Preferred Securities, the Trust may merge with or into, consolidate,
  amalgamate, or be replaced by or convey, transfer or lease its properties and
  assets substantially as an entirety to a trust organized as such under the
  laws of any state; provided, that (i) such successor entity either (a)
                     --------                                           
  expressly assumes all of the obligations of the Trust with respect to the
  Preferred

<PAGE>
 
  Securities or (b) substitutes for the Preferred Securities other
  securities having substantially the same terms as the Preferred Securities
  (the "Successor Securities") so long as the Successor Securities rank the same
  as the Preferred Securities rank in priority with respect to distributions and
  payments upon liquidation, redemption and otherwise, (ii) the Depositor
  expressly appoints a trustee of such successor entity possessing the same
  powers and duties as the Property Trustee as the holder of the Debentures,
  (iii) the Successor Securities are listed or traded, or any Successor
  Securities will be listed upon notification of issuance, on any national
  securities exchange or other organization on which the Preferred Securities
  are then listed or traded, if any, (iv) such merger, consolidation,
  amalgamation, replacement, conveyance, transfer or lease does not cause the
  Preferred Securities (including any Successor Securities) to be downgraded by
  any nationally recognized statistical rating organization, (v) such merger,
  consolidation, amalgamation, replacement, conveyance, transfer or lease does
  not adversely affect the rights, preferences and privileges of the holders of
  the Preferred Securities (including any Successor Securities) in any material
  respect, (vi) such successor entity has a purpose identical to that of the
  Trust, (vii) prior to such merger, consolidation, amalgamation, replacement,
  conveyance, transfer or lease, the Depositor has received an Opinion of
  Counsel to the effect that (a) such merger, consolidation, amalgamation,
  replacement, conveyance, transfer or lease does not adversely affect the
  rights, preferences and privileges of the holders of the Preferred Securities
  (including any Successor Securities) in any material respect, and (b)
  following such merger, consolidation, amalgamation, replacement, conveyance,
  transfer or lease, neither the Trust nor such successor entity will be
  required to register as an investment company under the 1940 Act and (viii)
  the Depositor owns all of the Common Securities of such successor entity and
  guarantees the obligations of such successor entity under the Successor
  Securities at least to the extent provided by the Guarantee.  Notwithstanding
  the foregoing, the Trust shall not, except with the consent of holders of 100%
  in Liquidation Amount of the Preferred Securities, consolidate, amalgamate,
  merge with or into, be replaced by or convey, transfer or lease its properties
  and assets substantially as an entirety to any other entity or permit any
  other entity to consolidate, amalgamate, merge with or into, or replace it if
  such consolidation, amalgamation, merger, replacement, conveyance, transfer or
  lease would cause the Trust or the successor entity to be classified as other
  than a grantor trust for United States federal income tax purposes.

     of this Trust Agreement to such extent as shall be necessary to ensure that

     as a grantor trust at all times that any Trust Securities are outstanding
     or to ensure that the Trust will not be required to register as an
     investment company under the 1940 Act; provided, however, that in the case

     Trust Agreement shall become effective when notice thereof is given to the
     Securityholders.

            (b)  Except as provided in Section 1002(c) hereof, any provision

     majority (based upon Liquidation Amounts) of the Trust Securities then
     Outstanding and (ii) receipt by the Trustees of an Opinion of Counsel to

     (such consent being obtained in accordance with Section 603 or 606 hereof),
     this Trust Agreement may not be amended to (i) change the amount or timing
     of any Distribution on the Trust Securities or otherwise adversely affect
     the amount of any Distribution required to be made in respect of the Trust
     Securities as of a specified date or (ii) restrict the right of a
     Securityholder to institute suit for the enforcement of any such payment on

     the exemption from status of an investment company under the 1940 Act or
     fail or cease to be classified as a grantor trust for United States federal
     income tax purposes.

            (e)  Notwithstanding anything in this Trust Agreement to the
     contrary, without the consent of the Depositor, this Trust Agreement may

     required provision shall control.  If any provision of this Trust Agreement
     modifies or excludes any provision of the Trust Indenture Act which may be
     so modified or excluded, the latter provision shall be deemed to apply to
     this Trust Agreement as so modified or excluded, as the case may be.

Re:  MCI Capital II ____% Cumulative Quarterly Income Preferred Securities,
     ---------------------------------------------------------------------
     Series A
     --------


Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the MCI
Capital II ___% Cumulative Quarterly Income Preferred Securities, Series A (the
"Preferred Securities"), of MCI Capital II, a Delaware business trust (the
"Issuer"), formed pursuant to a Trust Agreement between MCI Communications
Corporation ("MCI") and Wilmington Trust Company, as Trustee.  The payment of
distributions on the Preferred Securities and payments due upon liquidation of
Issuer or redemption of the Preferred Securities, to the extent the Issuer has
funds available for the payment thereof, are guaranteed by MCI to the extent set
forth in a Guarantee Agreement dated ________ __, 1996 by MCI with respect to
the Preferred Securities.  MCI and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement dated _________ __, 1996 by and among the Underwriters,
the Issuer and MCI, and the Underwriters wish to take delivery of the Preferred
Securities through DTC. Wilmington Trust Company is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:


     1.  Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about ________ __, 1996, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") 

                                       1

<PAGE>
 
registered in the name of DTC's Preferred Securities nominee, Cede & Co.,
representing an aggregate of __________ Preferred Securities and bearing the
following legend:

     Unless this certificate is presented by an authorized representative of The
     Depository Trust Company, a New York corporation ("DTC"), to Issuer or its
     agent for registration of transfer, exchange, or payment, and any
     certificate issued is registered in the name of Cede & Co. or in such other
     name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
     HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
     the registered owner hereof, Cede & Co., has an interest herein.

     2.  The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3.  In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4.  In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying:  (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means 
(e.g., legible telecopy, registered or certified mail, overnight delivery) in a

                                       2

timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before the Publication
Date. The Issuer or the Transfer Agent and Registrar will forward such notice
either in a separate secure transmission for each CUSIP number or in a secure
transmission of multiple CUSIP numbers (if applicable) that includes a manifest
or list of each CUSIP number submitted in that transmission. (The party sending
such notice shall have a method to verify subsequently the use of such means and
the timeliness Of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.

Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4.  Such redemption notice shall be
sent to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190,
and receipt of such notice shall be confirmed by telephoning (516) 227-4070.

     8.  Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be received by

transaction (e.g., tender made and accepted in response to the Issuer's or the
             - -                                                              
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion:  

                                       4

countersign a new Global Certificate; or (b) may make an appropriate notation on
the Global Certificate indicating the date and amount of such reduction.

     11.  DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law.  Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any

and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13.  This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

to advance funds on behalf of MCI Capital II.

<PAGE>
 
            (b)  Notice of redemption shall be given by the Property Trustee
     by first-class mail, postage prepaid, mailed not less than 30 nor more than
     60 days prior to the Redemption Date to each Holder of Trust Securities to

     All notices of redemption shall state:

                        (i)     the Redemption Date;

                       (ii)     the Redemption Price;

                      (iii)     the CUSIP number;

            Securities are to be redeemed, the identification and the total
            Liquidation Amount of the particular Trust Securities to be
            redeemed; and

                        (v)     that on the Redemption Date the Redemption Price
            will become due and payable upon each such Trust Security to be
            redeemed and that distributions thereon will cease to accrue on and
            after said date.

            (c)  The Trust Securities redeemed on each Redemption Date shall

     Securities shall be made and the Redemption Price shall be payable on each
     Redemption Date only to the extent that the Trust has funds then on hand
     and available in the Payment Account for the payment of such Redemption
     Price.

            (d)  If the Property Trustee gives a notice of redemption in
     respect of any Preferred Securities, then, by 12:00 noon, New York City
     time, on the Redemption Date, subject to Section 402(c), the Property
     Trustee will, so long as the Preferred Securities are in book-entry-only
     form, irrevocably deposit with the Clearing Agency for the Preferred
     Securities funds sufficient to pay the applicable Redemption Price and will
     give such Clearing Agency irrevocable instructions and authority to pay the
     Redemption Price to the holders thereof.  If the Preferred Securities are
     no longer in book-entry-only form, the Property Trustee, subject to Section
     402(c), will irrevocably deposit with the Paying Agent funds sufficient to
     pay the applicable Redemption Price and will give the Paying Agent
     irrevocable instructions and authority to pay the Redemption Price to the

     Notwithstanding the foregoing, Distributions payable on or prior to the
     Redemption Date for 

                                      22


<PAGE>
 
     any Trust Securities called for redemption shall be payable to the Holders
     of such Trust Securities as they appear on the Register for the Trust
     Securities on the relevant record dates for the related Distribution Dates.
     If notice of redemption shall have been given and funds deposited as
     required, then upon the date of such deposit, all rights of Securityholders
     holding Trust Securities so called for redemption will cease, except the
     right of such Securityholders to receive the Redemption Price and any
     Distribution payable on or prior to the Redemption Date, but without
     interest, and such Securities will cease to be outstanding. In the event
     that any date on which any Redemption Price is payable is not a Business
     Day, then payment of the Redemption Price payable on such date will be made
     on the next succeeding day that is a Business Day (and without any interest
     or other payment in respect of any such delay), except that, if such
     Business Day falls in the next calendar year, such payment will be made on
     the immediately preceding Business Day, in each case, with the same force
     and effect as if made on such date. In the event that payment of the
     Redemption Price in respect of any Trust Securities called for redemption
     is improperly withheld or refused and not paid either by the Trust or by
     the Depositor pursuant to the Guarantee, Distributions on such Trust
     Securities will continue to accrue, at the then applicable rate, from the
     Redemption Date originally established by the Trust for such Trust
     Securities to the date such Redemption Price is actually paid, in which
     case the actual payment date will be the date fixed for redemption for
     purposes of calculating the Redemption Price.

            (e)  Payment of the Redemption Price on the Trust Securities
     shall be made to the recordholders thereof as they appear on the Securities
     Register for the Trust Securities on the relevant record date, which shall
     be one Business Day prior to the relevant Redemption Date; provided,
                                                                -------- 
     however, that in the event that the Preferred Securities do not remain in
     -------                                                                  
     book-entry-only form, the relevant record date shall be the date fifteen
     days prior to the relevant Redemption Date.

            (f)  Subject to Section 403(a), if less than all the Outstanding
     Trust Securities are to be redeemed on a Redemption Date, then the
     aggregate Liquidation Amount of Trust Securities to be redeemed shall be
     allocated on a pro rata basis (based on Liquidation Amounts) among the
     Common Securities and the Preferred Securities.  The particular Preferred
     Securities to be redeemed shall be selected on a pro rata basis (based upon
     Liquidation Amounts) not more than 60 days prior to the Redemption Date by
     the Property Trustee from the Outstanding Preferred Securities not

                                      23

     previously called for redemption, by such method (including, without
     limitation, by lot) as the Property Trustee shall deem fair and appropriate
     and which may provide for the selection for redemption of portions (equal
     to $25 or an integral multiple of $25 in excess thereof) of the Liquidation
     Amount of Preferred Securities of a denomination larger than $25.  The
     Property Trustee shall promptly notify the Security Registrar in writing of
     the Preferred Securities selected for redemption and, in the case of any
     Preferred Securities selected for partial redemption, the Liquidation
     Amount thereof to be redeemed.  For all purposes of this Trust Agreement,
     unless the context otherwise requires, all provisions relating to the
     redemption of Preferred Securities shall relate, in the case of any
     Preferred Securities redeemed or to be redeemed only in part, to the
     portion of the Liquidation Amount of Preferred Securities that has been or
     is to be redeemed.

     Common Securities and the Preferred Securities based on the Liquidation
     Amount of the Trust Securities; provided, however, that if on any

     Debenture Event of Default shall have occurred and be continuing, no

     Securities, shall be made unless payment in full in cash of all accumulated
     and unpaid Distributions (including Additional Amounts, if applicable) on
     all Outstanding Preferred Securities for all Distribution periods
     terminating on or prior thereto, or in the case of payment of the
     Redemption Price the full amount of such Redemption Price on all
     Outstanding Preferred Securities, shall have been made or provided for, and
     all funds immediately available to the Property Trustee shall first be
     applied to the payment in full in cash of all Distributions (including
     Additional Amounts, if applicable) on, or the Redemption Price of,
     Preferred Securities then due and payable.

            (b)  In the case of the occurrence of any Event of Default
     resulting from a Debenture Event of Default, the Holder of Common
     Securities will be deemed to have waived any right to act with respect to
     any such Event of Default under this Trust Agreement until the effect of
     all such

     Events of Default with respect to the Preferred Securities have been cured,
     waived or otherwise eliminated. Until any such Event of Default under this
     Trust Agreement with respect to the Preferred Securities has been so cured,
     waived or otherwise eliminated, the Property Trustee shall act solely on
     behalf of the Holders of the Preferred Securities and not the Holder of the
     Common Securities, and only the Holders of the Preferred Securities will
     have the right to direct the Property Trustee to act on their behalf.

     SECTION 404.  Payment Procedures
                   ------------------

            Payments of Distributions (including Additional Amounts, if
  applicable) in respect of the Preferred Securities shall be made by check
  mailed to the address of the Person entitled thereto as such address shall

  a Clearing Agency, such Distributions shall be made to the Clearing Agency in
  immediately available funds, which shall credit the relevant Persons' accounts

  local tax and information returns and reports required to be filed by or in
  respect of the Trust.  In this regard, the Administrative Trustees shall (a)
  prepare and file (or cause to be prepared and filed) the appropriate Internal
  Revenue Service Form required to be filed in respect of the Trust in each
  taxable year of the Trust and (b) prepare and furnish (or cause to be prepared
  and furnished) to each Securityholder the appropriate Internal Revenue Service
  form required to be furnished to such Securityholder or the information
  required to be provided on such form.  The Administrative Trustees shall
  provide the Depositor and the Property Trustee with a copy of all such returns
  and reports promptly after such filing or furnishing.  The Trustees shall

  Certificates bearing the manual signatures of individuals who were, at the
  time when such signatures shall have been affixed, authorized to sign on
  behalf of the Trust, shall be validly issued and entitled to the benefits of
  this Trust Agreement, notwithstanding that such individuals or any of them
  shall have ceased to be so authorized prior to the delivery of such Trust
  Securities Certificates or did not hold such offices at the date of delivery
  of such Trust Securities Certificates.  A transferee of a Trust Securities
  Certificate shall become a Securityholder, and shall be entitled to the rights
  and subject to the obligations of a Securityholder hereunder, upon due
  registration of such Trust Securities Certificate in such transferee's name
  pursuant to Sections 504, 511 and 513.

  to or upon the written order of the Depositor, signed by its chairman of the
  board, its president, any executive vice president, senior vice president or
  any vice president, treasurer or assistant treasurer or controller without
  further corporate action by the Depositor, in authorized denominations.

  SECTION  504.  Registration of Transfer and Exchange of Preferred Securities
                 -------------------------------------------------------------
                  Certificates
                  ------------

            The Depositor shall keep or cause to be kept, at the office or
  agency maintained pursuant to Section 508, a register or registers for the
  purpose of registering Trust Securities Certificates and transfers and
  exchanges of Preferred Securities Certificates (the "Securities Register") in
  which, the registrar designated by the Depositor (the "Securities Registrar"),
  subject to such reasonable regulations as it may prescribe, shall provide for
  the registration of Preferred Securities Certificates and Common Securities
  Certificates (subject to Section 510 in the case of the Common Securities
  Certificates) and registration of transfers and exchanges of Preferred
  Securities Certificates as herein provided.  The Bank shall be the initial
  Securities Registrar.

            Upon surrender for registration of transfer of any Preferred
  Securities Certificate at the office or agency maintained pursuant to Section
  508, the Administrative Trustees or any one of them shall execute and deliver,
  in the name of the designated transferee or transferees, one or more new
  Preferred Securities Certificates in authorized denominations of a like
  aggregate Liquidation Amount dated the date of execution by such
  Administrative Trustee or Trustees.  The Securities Registrar shall not be
  required to register the transfer of any Preferred Securities that have been
  called for redemption.  At the option of a Holder, Preferred Securities
  Certificates may be exchanged for other Preferred Securities Certificates in
  authorized denominations of the same class and of a like aggregate Liquidation
  Amount upon surrender of the Preferred Securities Certificates to be exchanged
  at the office or agency maintained pursuant to Section 508.

                                      27

            Every Preferred Securities Certificate presented or surrendered for
  registration of transfer or exchange shall be accompanied by a written
  instrument of transfer in form satisfactory to the Property Trustee and the
  Securities Registrar duly executed by the Holder or his attorney duly
  authorized in writing.  Each Preferred Securities Certificate surrendered for
  registration of transfer or exchange shall be cancelled and subsequently
  disposed of by the Property Trustee in accordance with its customary practice.

            No service charge shall be made for any registration of transfer or
  exchange of Preferred Securities Certificates, but the Securities Registrar
  may require payment of a sum sufficient to cover any tax or governmental
  charge that may be imposed in connection with any transfer or exchange of
  Preferred Securities Certificates.

  SECTION  505.  Mutilated, Destroyed, Lost or Stolen Trust Securities
                 -----------------------------------------------------
                 Certificates
                 ------------

         If (a) any mutilated Trust Securities Certificate shall be
  surrendered to the Securities Registrar, or if the Securities Registrar
  shall receive evidence to its satisfaction of the destruction, loss or
  theft of any Trust Securities Certificate and (b) there shall be delivered
  to the Securities Registrar and the Administrative Trustees such security
  or indemnity as may be required by them to save each of them harmless, then
  in the absence of notice that such Trust Securities Certificate shall have
  been acquired by a bona fide purchaser, the Administrative Trustees, or any
  one of them, on behalf of the Trust shall execute and make available for
  delivery, in exchange for or in lieu of any such mutilated, destroyed, lost
  or stolen Trust Securities Certificate, a new Trust Securities Certificate
  of like class, tenor and denomination.  In connection with the issuance of
  any new Trust Securities Certificate under this Section, the Administrative
  Trustees or the Securities Registrar may require the payment of a sum
  sufficient to cover any tax or other governmental charge that may be
  imposed in connection therewith.  Any duplicate Trust Securities
  Certificate issued pursuant to this Section shall constitute conclusive
  evidence of an undivided beneficial interest in the assets of the Trust, as
  if originally issued, whether or not the lost, stolen or destroyed Trust
  Securities Certificate shall be found at any time.

  SECTION 506.    Persons Deemed Securityholders
                  ------------------------------

            The Administrative Trustees or the Securities Registrar shall treat
  the Person in whose name any Trust Securities Certificate shall be registered
  in the Securities Register as the owner of such Trust Securities Certificate
  for the purpose of receiving distributions and for all other purposes
  whatsoever, and neither the Trustees nor the Securities Registrar shall be
  bound by any notice to the contrary.

  SECTION 507.    Access to List of Securityholders' Names and Addresses
                  ------------------------------------------------------

            The Administrative Trustees or the Depositor shall furnish or cause
  to be furnished (a) to the Property Trustee, semi-annually on or before
  January 15 and July 15 in each year, a list, in such form as the Property
  Trustee may reasonably require, of the names and addresses of the
  Securityholders as of the most recent Record Date and (b) to the Property
  Trustee, promptly after receipt by any Administrative Trustee or the Depositor
  of a request therefor from the Property Trustee in order to enable the
  Property Trustee to discharge its obligations under this Trust Agreement, in
  each case to the extent such information is in the possession or control of
  the Administrative Trustees or the Depositor and is not identical to a
  previously supplied list or has not otherwise been received by the Property
  Trustee in its capacity as Securities Registrar.  The rights of
  Securityholders to communicate with other Securityholders with respect to
  their rights under this Trust Agreement or under the Trust Securities, and the
  corresponding rights of the Trustee shall be as provided in the Trust
  Indenture Act.  Each Holder, by receiving and holding a Trust Securities
  Certificate, and each Owner shall be deemed to have agreed not to hold the
  Depositor, the Property Trustee or the Administrative Trustees accountable by
  reason of the disclosure of its name and address, regardless of the source
  from which such information was derived.

  SECTION 508.    Maintenance of Office or Agency
                  -------------------------------

            The Administrative Trustees shall maintain an office or offices or
  agency or agencies where Preferred Securities Certificates may be surrendered
  for registration of transfer or exchange and where notices and demands to or
  upon the Trustees in respect of the Trust Securities Certificates may be
  served.  The Administrative Trustees initially designate MCI Communications
  Corporation, 1801 Pennsylvania Avenue, N.W., Washington, D.C. 20006,
  Attention: Treasurer, as the office for such purposes. The

                                      29 


<PAGE>
 
  Administrative Trustees shall give prompt written notice to the Depositor and
  to the Securityholders of any change in the location of the Securities
  Register or any such office or agency.

  SECTION 509.    Appointment of Paying Agent.
                  ---------------------------

            The Paying Agent shall make distributions to Securityholders from
  the Payment Account and shall report the amounts of such distributions to the
  Property Trustee and the Administrative Trustees.  Any Paying Agent shall have
  the revocable power to withdraw funds from the Payment Account for the purpose
  of making the distributions referred to above.  The Administrative Trustees
  may revoke such power and remove the Paying Agent if such Trustees determine
  in their sole discretion that the Paying Agent shall have failed to perform
  its obligations under this Trust Agreement in any material respect.  The
  Paying Agent shall initially be the Bank, and any co-paying agent chosen by
  the Bank and acceptable to the Administrative Trustees and the Depositor.  Any
  Person acting as Paying Agent shall be permitted to resign as Paying Agent
  upon 30 days' written notice to the Administrative Trustees, the Property
  Trustee and the Depositor.  In the event that the Bank shall no longer be the
  Paying Agent or a successor Paying Agent shall resign or its authority to act
  be revoked, the Administrative Trustees shall appoint a successor that is
  acceptable to the Property Trustee and the Depositor to act as Paying Agent
  (which shall be a bank or trust company).  The Administrative Trustees shall
  cause such successor Paying Agent or any additional Paying Agent appointed by
  the Administrative Trustees to execute and deliver to the Trustees an
  instrument in which such successor Paying Agent or additional Paying Agent
  shall agree with the Trustees that as Paying Agent, such successor Paying
  Agent or additional Paying Agent will hold all sums, if any, held by it for
  payment to the Securityholders in trust for the benefit of the Securityholders
  entitled thereto until such sums shall be paid to such Securityholders.  The
  Paying Agent shall return all unclaimed funds to the Property Trustee and upon
  removal of a Paying Agent such Paying Agent shall also return all funds in its
  possession to the Property Trustee.  The provisions of Sections 801, 803 and
  806 shall apply to the Bank also in its role as Paying Agent, for so long as
  the Bank shall act as Paying Agent and, to the extent applicable, to any other
  paying agent appointed hereunder.  Any reference in this Agreement to the
  Paying Agent shall include any co-paying agent unless the context requires
  otherwise.

  SECTION 510.  Ownership of Common Securities by Depositor.
                ------------------------------------------- 

            At each Time of Delivery, the Depositor shall acquire and retain
  beneficial and record ownership of the Common Securities.  To the fullest
  extent permitted by law, other than a transfer in connection with a
  consolidation or merger of the Depositor into another corporation, or any
  conveyance, transfer or lease by the Depositor of its properties and assets
  substantially as an entirety to any Person, pursuant to Section 801 of the
  Indenture, any attempted transfer of the Common Securities shall be void.  The
  Administrative Trustees shall cause each Common Securities Certificate issued

  TRANSFERABLE".

                ---------------------------------------------------------------
                Certificate.

            (a)  The Preferred Securities Certificates, upon original
     issuance, will be issued in the form of a typewritten Preferred Securities
     Certificate or Certificates representing Book-Entry Preferred Securities
     Certificates, to be delivered to The Depository Trust Company, the initial
     Clearing Agency, by, or on behalf of, the Trust.  Such Preferred Securities
     Certificate or Certificates shall initially be registered on the Securities
     Register in the name of Cede & Co., the nominee of the initial Clearing
     Agency, and no beneficial owner will receive a Definitive Preferred
     Securities Certificate representing such beneficial owner's interest in
     such Preferred Securities, except as provided in Section 513.  Unless and
     until Definitive Preferred Securities Certificates have been issued to
     beneficial owners pursuant to Section 513:

              (i)  the provisions of this Section 511(a) shall be in full
       force and effect;

             (ii)  the Securities Registrar and the Trustees shall be
       entitled to deal with the Clearing Agency for all purposes of this Trust
       Agreement relating to the Book-Entry Preferred Securities Certificates
       (including the payment of the Liquidation Amount of and Distributions on
       the Book-Entry Preferred Securities and the giving of instructions or
       directions to Owners of Book-Entry Preferred Securities) as the sole
       Holder of Book-Entry Preferred Securities and shall have no obligations
       to the Owners thereof;

            (iii)  to the extent that the provisions of this Section 511
       conflict with any other provisions of this

                                      31

       Trust Agreement, the provisions of this Section 511 shall control; and

             (iv)  the rights of the Owners of the Book-Entry Preferred
       Securities Certificates shall be exercised only through the Clearing
       Agency and shall be limited to those established by law and agreements
       between such Owners and the Clearing Agency and/or the Clearing Agency
       Participants.  Pursuant to the Certificate Depository Agreement, unless
       and until Definitive Preferred Securities Certificates are issued
       pursuant to Section 513, the initial Clearing Agency will make book-entry
       transfers among the Clearing Agency Participants and receive and transmit
       payments on the Preferred Securities to such Clearing Agency
       Participants.

            (b)  A single Common Securities Certificate representing the
     Common Securities shall be issued to the Depositor in the form of a
     definitive Common Securities Certificate.

  SECTION 512.  Notices to Clearing Agency.
                -------------------------- 

            To the extent that a notice or other communication to the Owners is
  required under this Trust Agreement, unless and until Definitive Preferred
  Securities Certificates shall have been issued to Owners pursuant to Section
  513, the Trustees shall give all such notices and communications specified
  herein to be given to Owners to the Clearing Agency, and shall have no
  obligations to the Owners.

  SECTION 513.  Definitive Preferred Securities Certificates.
                -------------------------------------------- 

            If (a) the Depositor advises the Trustees in writing that the
  Clearing Agency is no longer willing or able to properly discharge its
  responsibilities with respect to the Preferred Securities Certificates, and
  the Depositor is unable to locate a qualified successor, (b) the Depositor at
  its option advises the Trustees in writing that it elects to terminate the
  book-entry system through the Clearing Agency, or (c) after the occurrence of
  a Debenture Event of Default, Owners of Preferred Securities Certificates
  representing beneficial interests aggregating at least a majority of the
  Liquidation Amount advise the Property Trustee in writing that the
  continuation of a book-entry system through the Clearing Agency is no longer
  in the best interest of the Owners of Preferred Securities Certificates, then
  the Property Trustee shall notify the Clearing Agency and the Clearing Agency
  shall notify all Owners of Preferred Securities Certificates and the other
  Trustees of the 

                                      32

                                      
<PAGE>
 
  occurrence of any such event and of the availability of the Definitive
  Preferred Securities Certificates to Owners of such class or classes, as
  applicable, requesting the same. Upon surrender to the Property Trustee of the
  typewritten Preferred Securities Certificate or Certificates representing the
  Book-Entry Preferred Securities Certificates by the Clearing Agency,
  accompanied by registration instructions, the Administrative Trustees, or any
  one of them, shall execute the Definitive Preferred Securities Certificates in
  accordance with the instructions of the Clearing Agency. Neither the
  Securities Registrar nor the Trustees shall be liable for any delay in
  delivery of such instructions and may conclusively rely on, and shall be
  protected in relying on, such instructions. Upon the issuance of Definitive
  Preferred Securities Certificates, the Trustees shall recognize the Holders of
  the Definitive Preferred Securities Certificates as Securityholders. The
  Definitive Preferred Securities Certificates shall be printed, lithographed or
  engraved or may be produced in any other manner as is reasonably acceptable to
  the Administrative Trustees, as evidenced by the execution thereof by the
  Administrative Trustees or any one of them.

  SECTION 514.  Rights of Securityholders.
                ------------------------- 

            (a)  The legal title to the Trust Property is vested exclusively in
  the Property Trustee (in its capacity as such) in accordance with Section 209,
  and the Securityholders shall not have any right or title therein other than
  the undivided beneficial interest in the assets of the Trust conferred by
  their Trust Securities and they shall have no right to call for any partition
  or division of property, profits or rights of the Trust except as described
  below.  The Trust Securities shall be personal property giving only the rights
  specifically set forth therein and in this Trust Agreement.  The Trust
  Securities shall have no preemptive or similar rights and when issued and
  delivered to Securityholders against payment of the purchase price therefor
  will be fully paid and nonassessable by the Trust.  The Holders of the Trust
  Securities, in their capacities as such, shall be entitled to the same
  limitation of personal liability extended to stockholders of private
  corporations for profit organized under the General Corporation Law of the
  State of Delaware.

            (b)  For so long as any Preferred Securities remain Outstanding, if,
  upon a Debenture Event of Default, the Debenture Trustee fails or the holders
  of not less than 25% in principal amount of the outstanding Debentures fail to
  declare the principal of all of the Debentures to be immediately due and
  payable, the Holders of at least 25% in

                                      33 


<PAGE>
 
  Liquidation Amount of the Preferred Securities then Outstanding shall have
  such right by a notice in writing to the Depositor and the Debenture Trustee;
  and upon any such declaration such principal amount of and the accrued
  interest on all of the Debentures shall become immediately due and payable,
  provided that the payment of principal and interest on such Debentures shall
  remain subordinated to the extent provided in the Indenture.

            (c)  For so long as any Preferred Securities remain Outstanding, to
  the fullest extent permitted by law and subject to the terms of this Trust
  Agreement, if, upon a Debenture Event of Default specified in Section 501(1)
  or 501(2) of the Indenture, any Holder of Preferred Securities shall have the
  right to directly institute a proceeding for enforcement of payment to such
  Holder of the principal amount of or interest on the Debentures having a
  principal amount equal to the Liquidation Amount of the Preferred Securities
  of such Holder (a "Direct Action").  In connection with such Direct Action,
  the rights of the Holders of the Common Securities will be subrogated to the
  rights of any Holder of the Preferred Securities to the extent of any payment
  made by the Depositor to such Holder of Preferred Securities in such Direct
  Action.  Except as set forth in this Section 514(c), the Holders of Preferred
  Securities will not be able to exercise directly any other remedy available to
  the holders of the Debentures or assert directly any other rights in respect
  of the Debentures.

  SECTION 601.   Limitations on Voting Rights
                 ----------------------------

            (a)  Except as provided in this Section, in Sections 810 and
     1002 and in the Indenture and as otherwise required by law, no Holder of
     Preferred Securities shall have any right to vote or in any manner
     otherwise control the administration, operation and management of the Trust
     or the obligations of the parties hereto, nor shall anything herein set
     forth, or contained in the terms of the Trust Securities Certificates, be
     construed so as to constitute the Securityholders from time to time as
     partners or members of an association.

            (b)  So long as any Debentures are held by the Property Trustee,
     the Trustees shall not (i) direct the time, method and place of conducting
     any proceeding for any remedy available to the Debenture Trustee, or
     executing any trust or power conferred on the Debenture Trustee with
     respect to such Debentures, (ii) waive any past default

                                      34 


<PAGE>
 
     which is waiveable under Section 513 of the Indenture, (iii) exercise any
     right to rescind or annul a declaration that the principal of all the
     Debentures shall be due and payable or (iv) consent to any amendment,
     modification or termination of the Indenture or the Debentures, where such
     consent shall be required, without, in each case, obtaining the prior
     approval of the Holders of at least a majority in Liquidation Amount of all
     Outstanding Preferred Securities; provided, however, that where a consent
                                       --------  -------  
     under the Indenture would require the consent of each Holder of Debentures
     affected thereby, no such consent shall be given by the Property Trustee
     without the prior written consent of each Holder of Preferred Securities.
     The Trustees shall not revoke any action previously authorized or approved
     by a vote of the Holders of Preferred Securities, except by a subsequent
     vote of the Holders of Preferred Securities. The Property Trustee shall
     notify all Holders of the Preferred Securities of any notice of default
     received from the Debenture Trustee with respect to the Debentures. In
     addition to obtaining the foregoing approvals of the Holders of the
     Preferred Securities, prior to taking any of the foregoing actions, the
     Trustees shall, at the expense of the Depositor, obtain an Opinion of
     Counsel experienced in such matters to the effect that the Trust will not
     be classified as an association taxable as a corporation for United States
     federal income tax purposes on account of such action.

            (c)  If any proposed amendment to the Trust Agreement provides
     for, or the Trustees otherwise propose to effect, (i) any action that would
     adversely affect in any material respect the powers, preferences or special
     rights of the Preferred Securities, whether by way of amendment to the
     Trust Agreement or otherwise, or (ii) the dissolution, winding-up or
     termination of the Trust, other than pursuant to the terms of this Trust
     Agreement, then the Holders of Outstanding Preferred Securities as a class
     will be entitled to vote on such amendment or proposal and such amendment
     or proposal shall not be effective except with the approval of the Holders
     of at least a majority in Liquidation Amount of the Outstanding Preferred
     Securities.  No amendment to this Trust Agreement may be made if, as a
     result of such amendment, the Trust would be classified as an association
     taxable as a corporation for United States federal income tax purposes.

  SECTION 602.   Notice of Meetings.
                 ------------------

            Notice of all meetings of the Preferred Securityholders, stating the
  time, place and purpose of the meeting, shall be given by the Property Trustee
  pursuant to Section 1008 to each Preferred Securityholder of record, at his
  registered address, at least 15 days and not more than 90 days before the
  meeting.  At any such meeting, any business properly before the meeting may be
  so considered whether or not stated in the notice of the meeting.  Any
  adjourned meeting may be held as adjourned without further notice.

  SECTION 603.   Meetings of Preferred Securityholders.
                 -------------------------------------

            No annual meeting of Securityholders is required to be held.  The
  Administrative Trustees, however, shall call a meeting of Securityholders to
  vote on any matter upon the written request of the Preferred Securityholders
  of record of 25% of the Preferred Securities (based upon their Liquidation
  Amount) and the Administrative Trustees or the Property Trustee may, at any
  time in their discretion, call a meeting of Preferred Securityholders to vote
  on any matters as to which Preferred Securityholders are entitled to vote.

            Preferred Securityholders of record of 50% of the Outstanding
  Preferred Securities (based upon their Liquidation Amount), present in person
  or by proxy, shall constitute a quorum at any meeting of Securityholders.

            If a quorum is present at a meeting, an affirmative vote by the
  Preferred Securityholders of record present, in person or by proxy, holding
  more than a majority of the Preferred Securities (based upon their Liquidation
  Amount) held by the Preferred Securityholders of record present, either in
  person or by proxy, at such meeting shall constitute the action of the
  Securityholders, unless this Trust Agreement requires a greater number of
  affirmative votes.

  SECTION 604.   Voting Rights
                 -------------

            Securityholders shall be entitled to one vote for each $25 of
  Liquidation Amount represented by their Trust Securities in respect of any
  matter as to which such Securityholders are entitled to vote.

                                      36


<PAGE>
 
  SECTION 605.   Proxies, etc.
                 -------------      

            At any meeting of Securityholders, any Securityholder entitled to
  vote thereat may vote by proxy, provided that no proxy shall be voted at any
  meeting unless it shall have been placed on file with the Administrative
  Trustees, or with such other officer or agent of the Trust as the
  Administrative Trustees may direct, for verification prior to the time at
  which such vote shall be taken.  Pursuant to a resolution of the Property
  Trustee, proxies may be solicited in the name of the Property Trustee or one
  or more officers of the Property Trustee.  Only Securityholders of record
  shall be entitled to vote.  When Trust Securities are held jointly by several
  persons, any one of them may vote at any meeting in person or by proxy in
  respect of such Trust Securities, but if more than one of them shall be
  present at such meeting in person or by proxy, and such joint owners or their
  proxies so present disagree as to any vote to be cast, such vote shall not be
  received in respect of such Trust Securities.  A proxy purporting to be
  executed by or on behalf of a Securityholder shall be deemed valid unless
  challenged at or prior to its exercise, and the burden of proving invalidity
  shall rest on the challenger.  No proxy shall be valid more than three years
  after its date of execution.

  SECTION 606.    Securityholder Action by Written Consent.
                  ----------------------------------------

            Any action which may be taken by Securityholders at a meeting may be
  taken without a meeting if Securityholders holding more than a majority of all
  Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
  vote in respect of such action (or such larger proportion thereof as shall be
  required by any express provision of this Trust Agreement) shall consent to
  the action in writing.

  SECTION 607.    Record Date for Voting and Other Purposes
                  -----------------------------------------

            For the purposes of determining the Securityholders who are entitled
  to notice of and to vote at any meeting or by written consent, or to
  participate in any distribution on the Trust Securities in respect of which a
  record date is not otherwise provided for in this Trust Agreement, or for the
  purpose of any other action, the Administrative Trustees may from time to time
  fix a date, not more than 90 days prior to the date of any meeting of
  Securityholders or the payment of a distribution or other action, as the case
  may be, as a record date for the determination of the identity of the
  Securityholders of record for such purposes.

                                      37


<PAGE>
 
  SECTION 608.    Acts of Securityholders
                  -----------------------

            Any request, demand, authorization, direction, notice, consent,
  waiver or other action provided or permitted by this Trust Agreement to be
  given, made or taken by Securityholders or Owners may be embodied in and
  evidenced by one or more instruments of substantially similar tenor signed by
  such Securityholders or Owners in person or by an agent duly appointed in
  writing; and, except as otherwise expressly provided herein, such action shall
  become effective when such instrument or instruments are delivered to an
  Administrative Trustee.  Such instrument or instruments (and the action
  embodied therein and evidenced thereby) are herein sometimes referred to as
  the "Act" of the Securityholders or Owners signing such instrument or
  instruments.  Proof of execution of any such instrument or of a writing
  appointing any such agent shall be sufficient for any purpose of this Trust
  Agreement and (subject to Section 801) conclusive in favor of the Trustees, if
  made in the manner provided in this Section.

            The fact and date of the execution by any Person of any such
  instrument or writing may be proved by the affidavit of a witness of such
  execution or by a certificate of a notary public or other officer authorized
  by law to take acknowledgments of deeds, certifying that the individual
  signing such instrument or writing acknowledged to him the execution thereof.
  Where such execution is by a signer acting in a capacity other than his
  individual capacity, such certificate or affidavit shall also constitute
  sufficient proof of his authority.  The fact and date of the execution of any
  such instrument or writing, or the authority of the Person executing the same,
  may also be proved in any other manner which any Trustee receiving the same
  deems sufficient.

            The ownership of Preferred Securities shall be proved by the
  Securities Register.

            Any request, demand, authorization, direction, notice, consent,
  waiver or other Act of the Securityholder of any Trust Security shall bind
  every future Securityholder of the same Trust Security and the Securityholder
  of every Trust Security issued upon the registration of transfer thereof or in
  exchange therefor or in lieu thereof in respect of anything done, omitted or
  suffered to be done by the Trustees or the Trust in reliance thereon, whether
  or not notation of such action is made upon such Trust Security.

                                      38


<PAGE>
 
            Without limiting the foregoing, a Securityholder entitled hereunder
  to take any action hereunder with regard to any particular Trust Security may
  do so with regard to all or any part of the Liquidation Amount of such Trust
  Security or by one or more duly appointed agents each of which may do so
  pursuant to such appointment with regard to all or any part of such
  liquidation amount.

            If any dispute shall arise between the Securityholders and the
  Administrative Trustees or among such Securityholders or Trustees with respect
  to the authenticity, validity or binding nature of any request, demand,
  authorization, direction, consent, waiver or other Act of such Securityholder
  or Trustee under this Article VI, then the determination of such matter by the
  Property Trustee shall be conclusive with respect to such matter.

            A Securityholder may institute a legal proceeding directly against
  the Depositor under the Guarantee to enforce its rights under the Guarantee
  without first instituting a legal proceeding against the Guarantee Trustee (as
  defined in the Guarantee), the Trust or any person or entity.

  SECTION 609.    Inspection of Records
                  ---------------------

            Upon reasonable notice to the Administrative Trustees and the
  Property Trustee, the records of the Trust shall be open to inspection by
  Securityholders during normal business hours for any purpose reasonably
  related to such Securityholder's interest as a Securityholder.

                  ---------------------------------


            The Bank, the Property Trustee and the Delaware Trustee, each
  severally on behalf of and as to itself, hereby represents and warrants for

            (a)  the Bank is a Delaware banking corporation duly organized,
       validly existing and in good standing under the laws of the State of
       Delaware;

            (b)  the Bank has full corporate power, authority and legal
       right to execute, deliver and perform its

       obligations under this Trust Agreement and has taken all necessary action
       to authorize the execution, delivery and performance by it of this Trust
       Agreement;

            (c)  this Trust Agreement has been duly authorized, executed and
       delivered by the Bank and constitutes the valid and legally binding
       agreement of the Bank enforceable against it in accordance with its
       terms, subject to bankruptcy, insolvency, fraudulent transfer,
       reorganization, moratorium and similar laws of general applicability
       relating to or affecting creditors' rights and to general equity
       principles;

            (d)  the execution, delivery and performance by the Bank of this
       Trust Agreement has been duly authorized by all necessary corporate or
       other action on the part of the Bank, the Property Trustee and the
       Delaware Trustee and does not require any approval of stockholders of the
       Bank and such execution, delivery and performance will not (i) violate
       the Bank's charter or by-laws, (ii) violate any provision of, or
       constitute, with or without notice or lapse of time, a default under, or
       result in the creation or imposition of, any Lien on any properties
       included in the Trust Property pursuant to the provisions of, any
       indenture, mortgage, credit agreement, license or other agreement or
       instrument to which the Property Trustee, the Bank or the Delaware
       Trustee is a party or by which it is bound, or (iii) violate any law,
       governmental rule or regulation of the United States or the State of
       Delaware, as the case may be, governing the banking or trust powers of
       the Bank, the Property Trustee or the Delaware Trustee (as appropriate in
       context) or any order, judgment or decree applicable to the Property
       Trustee, the Bank or the Delaware Trustee;

            (e)  neither the authorization, execution or delivery by the
       Bank of this Trust Agreement nor the consummation of any of the
       transactions by the Bank, the Property Trustee or the Delaware Trustee
       (as appropriate in context) contemplated herein or therein requires the
       consent or approval of, the giving of notice to, the registration with or
       the taking of any other action with respect to any governmental authority
       or agency under any existing federal law governing the banking or trust
       powers of the Bank, the Property Trustee or the Delaware Trustee, as the
       case may be, under the laws of the United States or the State of
       Delaware;

                                      40


<PAGE>
 
            (f)  there are no proceedings pending or, to the best of each of
       the Bank's, the Property Trustee's and the Delaware Trustee's knowledge,
       threatened against or affecting the Bank, the Property Trustee or the
       Delaware Trustee in any court or before any governmental authority,
       agency or arbitration board or tribunal which, individually or in the
       aggregate, would materially and adversely affect the Trust or would
       question the right, power and authority of the Bank, the Property Trustee
       or the Delaware Trustee, as the case may be, to enter into or perform its
       obligations as one of the Trustees under this Trust Agreement.

  SECTION 702.   Representations and Warranties of Depositor.
                 ------------------------------------------- 


            The Depositor hereby represents and warrants for the benefit of the
  Securityholders that:

            (a) the Trust Securities Certificates issued at each Time of
       Delivery on behalf of the Trust have been duly authorized and will have
       been duly and validly executed, issued and delivered by the Trustees
       pursuant to the terms and provisions of, and in accordance with the
       requirements of, this Trust Agreement and the Securityholders will be, as
       of such date, entitled to the benefits of this Trust Agreement; and

            (b) there are no taxes, fees or other governmental charges payable
       by the Trust (or the Trustees on behalf of the Trust) under the laws of
       the State of Delaware or any political subdivision thereof in connection
       with the execution, delivery and performance by the Bank, the Property
       Trustee or the Delaware Trustee, as the case may be, of this Trust
       Agreement.

                                 ARTICLE VIII
                                 ------------
                                 The Trustees
                                 ------------

  SECTION 801.   Certain Duties and Responsibilities
                 -----------------------------------

            (a)  The duties and responsibilities of the Trustees shall be as
     provided by this Trust Agreement and, in the case of the Property Trustee,
     by the Trust Indenture Act.  Notwithstanding the foregoing, no provision of
     this Trust Agreement shall require the Trustees to expend or risk their own
     funds or otherwise incur any financial liability in the performance of any
     of their duties hereunder, or in the exercise of any of their rights or
     powers, if they shall have reasonable grounds for believing that repayment
     of such funds or adequate indemnity against such risk or liability

                                      41 


<PAGE>
 
     is not reasonably assured to it. Whether or not therein expressly so
     provided, every provision of this Trust Agreement relating to the conduct
     or affecting the liability of or affording protection to the Trustees shall
     be subject to the provisions of this Section. Nothing in this Trust
     Agreement shall be construed to release the Property Trustee from liability
     for its own negligent action, its own negligent failure to act, or its own
     willful misconduct. To the extent that, at law or in equity, an
     Administrative Trustee has duties (including fiduciary duties) and
     liabilities relating thereto to the Trust or to the Securityholders, such
     Administrative Trustee shall not be liable to the Trust or to any
     Securityholder for such Trustee's good faith reliance on the provisions of
     this Trust Agreement. The provisions of this Trust Agreement, to the extent
     that they restrict the duties and liabilities of the Administrative
     Trustees otherwise existing at law or in equity, are agreed by the
     Depositor and the Securityholders to replace such other duties and
     liabilities of the Administrative Trustees.

            (b)   All payments made by the Property Trustee or a Paying Agent
     in respect of the Trust Securities shall be made only from the revenue and
     proceeds from the Trust Property and only to the extent that there shall be
     sufficient revenue or proceeds from the Trust Property to enable the
     Property Trustee or a Paying Agent to make payments in accordance with the
     terms hereof.  Each Securityholder, by its acceptance of a Trust Security,
     agrees that it will look solely to the revenue and proceeds from the Trust
     Property to the extent legally available for distribution to it as herein
     provided and that the Trustees are not personally liable to it for any
     amount distributable in respect of any Trust Security or for any other
     liability in respect of any Trust Security.  This Section 801(b) does not
     limit the liability of the Trustees expressly set forth elsewhere in this
     Trust Agreement or, in the case of the Property Trustee, in the Trust
     Indenture Act.

            (c)  No provision of this Trust Agreement shall be construed to
     relieve the Property Trustee from liability for its own negligent action,
     its own negligent failure to act, or its own willful misconduct, except
     that:

            (i)  the Property Trustee shall not be liable for any error      
       of judgment made in good faith by an authorized officer of the Property
       Trustee, unless it shall be proved that the Property Trustee was
       negligent in ascertaining the pertinent facts;

                                      42


<PAGE>
 
            (ii)  the Property Trustee shall not be liable with respect
       to any action taken or omitted to be taken by it in good faith in
       accordance with the direction of the Holders of not less than a majority
       in Liquidation Amount of the Trust Securities relating to the time,
       method and place of conducting any proceeding for any remedy available to
       the Property Trustee, or exercising any trust or power conferred upon the
       Property Trustee under this Trust Agreement;

            (iii)  the Property Trustee's sole duty with respect to the
       custody, safe keeping and physical preservation of the Debentures and the
       Payment Account shall be to deal with such Property in a similar manner
       as the Property Trustee deals with similar property for its own account,
       subject to the protections and limitations on liability afforded to the
       Property Trustee under this Trust Agreement and the Trust Indenture Act;

            (iv)  the Property Trustee shall not be liable for any
       interest on any money received by it except as it may otherwise agree
       with the Depositor, and money held by the Property Trustee need not be
       segregated from other funds held by it except in relation to the Payment
       Account maintained by the Property Trustee pursuant to Section 301 and
       except to the extent otherwise required by law; and

            (v)  the Property Trustee shall not be responsible for
       monitoring the compliance by the Administrative Trustees or the Depositor
       with their respective duties under this Trust Agreement, nor shall the
       Property Trustee be liable for the default or misconduct of the
       Administrative Trustees or the Depositor.

  SECTION 802.   Certain Notices.
                 ---------------- 

            Within five Business Days after the occurrence of any Event of
  Default actually known to the Property Trustee, the Property Trustee shall
  transmit, in the manner and to the extent provided in Section 1008, notice of
  such Event of Default to the Securityholders, the Administrative Trustees and
  the Depositor, unless such Event of Default shall have been cured or waived.

            Within five Business Days after the receipt of notice of the
  Depositor's exercise of its right to defer the payment of interest on the
  Debentures pursuant to the Indenture, the Administrative Trustee shall
  transmit, in the manner and to the extent provided in Section 1008, notice of

                                      43

  such exercise to the Securityholders and the Property Trustee, unless such
  exercise shall have been revoked.

  SECTION 803.   Certain Rights of Property Trustee.
                 -----------------------------------

            Subject to the provisions of Section 801:

            (a)  the Property Trustee may rely and shall be protected in
       acting or refraining from acting in good faith upon any resolution,
       Opinion of Counsel, certificate, written representation of a Holder or
       transferee, certificate of auditors or any other certificate, statement,
       instrument, opinion, report, notice, request, consent, order, appraisal,
       bond, debenture, note, other evidence of indebtedness or other paper or
       document believed by it to be genuine and to have been signed or
       presented by the proper party or parties;

            (b)  if (i) in performing its duties under this Trust Agreement
       the Property Trustee is required to decide between alternative courses of
       action or (ii) in construing any of the provisions of this Trust
       Agreement the Property Trustee finds the same ambiguous or inconsistent
       with any other provisions contained herein or (iii) the Property Trustee
       is unsure of the application of any provision of this Trust Agreement,
       then, except as to any matter as to which the Preferred Securityholders
       are entitled to vote under the terms of this Trust Agreement, the
       Property Trustee shall deliver a notice to the Depositor requesting
       written instructions of the Depositor as to the course of action to be
       taken and the Property Trustee shall take such action, or refrain from
       taking such action, as the Property Trustee shall be instructed in
       writing to take, or to refrain from taking, by the Depositor; provided,
                                                                     -------- 
       however, that if the Property Trustee does not receive such instructions
       -------                                                                 
       of the Depositor within ten Business Days after it has delivered such
       notice, or such reasonably shorter period of time set forth in such
       notice (which to the extent practicable shall not be less than two
       Business Days), it may, but shall be under no duty to, take or refrain
       from taking such action not inconsistent with this Trust Agreement as it
       shall deem advisable and in the best interests of the Securityholders, in
       which event the Property Trustee shall have no liability except for its
       own bad faith, negligence or willful misconduct;

            (c)  any direction or act of the Depositor or the Administrative
       Trustees contemplated by this Trust

                                      44

       Agreement shall be sufficiently evidenced by an Officers' Certificate;

            (d)  whenever in the administration of this Trust Agreement, the
       Property Trustee shall deem it desirable that a matter be established
       before undertaking, suffering or omitting any action hereunder, the
       Property Trustee (unless other evidence is herein specifically
       prescribed) may, in the absence of bad faith on its part, request and
       rely upon an Officers' Certificate which, upon receipt of such request,
       shall be promptly delivered by the Depositor or the Administrative
       Trustees;

            (e)  the Property Trustee shall have no duty to see to any
       recording, filing or registration of any instrument (including any
       financing or continuation statement or any filing under tax or securities
       laws) or any rerecording, refiling or reregistration thereof;

            (f)  the Property Trustee may consult with counsel (which
       counsel may be counsel to the Depositor or any of its Affiliates, and may
       include any of its employees) and the advice of such counsel shall be
       full and complete authorization and protection in respect of any action
       taken, suffered or omitted by it hereunder in good faith and in reliance
       thereon and in accordance with such advice; the Property Trustee shall
       have the right at any time to seek instructions concerning the
       administration of this Trust Agreement from any court of competent
       jurisdiction;

            (g)  the Property Trustee shall be under no obligation to
       exercise any of the rights or powers vested in it by this Trust Agreement
       at the request or direction of any of the Securityholders pursuant to
       this Trust Agreement, unless such Securityholders shall have offered to
       the Property Trustee reasonable security or indemnity against the costs,
       expenses and liabilities which might be incurred by it in compliance with
       such request or direction;

            (h)  the Property Trustee shall not be bound to make any
       investigation into the facts or matters stated in any resolution,
       certificate, statement, instrument, opinion, report, notice, request,
       consent, order, approval, bond, debenture, note or other evidence of
       indebtedness or other paper or document, unless requested in writing to
       do so by one or more Securityholders, but the Property Trustee may make
       such

            (i)  the Property Trustee may execute any of the trusts or
       powers hereunder or perform any duties hereunder either directly or by or
       through its agents or attorneys, provided that the Property Trustee shall

       Property Trustee shall deem it desirable to receive instructions with
       respect to enforcing any remedy or right or taking any other action
       hereunder the Property Trustee (i) may request instructions from the
       Holders of the Trust Securities which instructions may only be given by
       the Holders of the same proportion in Liquidation Amount of the Trust
       Securities as would be entitled to direct the Property Trustee under the

       Agreement, the Property Trustee shall not be under any obligation to take
       any action that is discretionary under the provisions of this Trust
       Agreement.

  No provision of this Trust Agreement shall be deemed to impose any duty or
  obligation on the Property Trustee to perform any act or acts or exercise any
  right, power, duty or obligation conferred or imposed on it, in any
  jurisdiction in which it shall be illegal, or in which the Property Trustee
  shall be unqualified or incompetent in accordance with applicable law, to
  perform any such act or acts, or to exercise any such right, power, duty or
  obligation.  No permissive power or authority available to the Property

                 ---------------------------------------------------
                 Trustees
                 --------

     Person that is eligible pursuant to the Trust Indenture Act to act as such
     and has a combined capital and surplus of at least $50,000,000.  If any
     such Person publishes reports of condition at least annually, pursuant to
     law or to the requirements of its supervising or examining authority, then
     for the purposes of this Section, the combined capital and surplus of such
     Person shall be deemed to be its combined capital and surplus as set forth
     in its most recent report of condition so published.  If at any time the
     Property Trustee with respect to the Trust Securities shall cease to be
     eligible in accordance with the provisions of this Section, it shall resign
     immediately in the manner and with the effect hereinafter specified in this
     Article.

            (b)  There shall at all times be one or more Administrative
     Trustees hereunder with respect to the Trust Securities.  Each
     Administrative Trustee shall be either a natural person who is at least 21
     years of age or a legal entity that shall act through one or more persons

            (c)  There shall at all times be a Delaware Trustee with
     respect to the Trust Securities.  The Delaware Trustee shall either be (i)

            If the Property Trustee has or shall acquire a conflicting interest

  either eliminate such interest or resign, to the extent and in the manner
  provided by, and subject to the provisions of, the Trust Indenture Act and
  this Trust Agreement.

  SECTION 809.   Co-Trustees and Separate Trustee.
                 -------------------------------- 

            Unless an Event of Default shall have occurred and be continuing, at

  Trust Indenture Act or of any jurisdiction in which any part of the Trust
  Property 

                                      48


<PAGE>
 
  may at the time be located, the Depositor and the Administrative Trustees, 
  by agreed action of the majority of such Trustees, shall have power to 
  appoint, and upon the written request of the Administrative Trustees, the
  Depositor shall for such purpose join with the Administrative Trustees in the
  execution, delivery and performance of all instruments and agreements
  necessary or proper to appoint, one or more Persons approved by the Property
  Trustee either to act as co-trustee, jointly with the Property Trustee, of all
  or any part of such Trust Property, or to the extent required by law to act as
  separate trustee of any such property, in either case with such powers as may
  be provided in the instrument of appointment, and to vest in such Person or
  Persons in the capacity aforesaid, any property, title, right or power deemed
  necessary or desirable, subject to the other provisions of this Section.  If
  the Depositor does not join in such appointment within 15 days after the
  receipt by it of a request so to do, or in case a Debenture Event of Default
  has occurred and is continuing, the Property Trustee alone shall have power to
  make such appointment.  Any co-trustee or separate trustee appointed pursuant
  to this Section shall either be (i) a natural person who is at least 21 years
  of age and a resident of the United States or (ii) a legal entity with its
  principal place of business in the United States that shall act through one or
  more persons authorized to bind such entity.

            Should any written instrument from the Depositor be required by any
  co-trustee or separate trustee so appointed for more fully confirming to such
  co-trustee or separate trustee such property, title, right, or power, any and
  all such instruments shall, on request, be executed, acknowledged and
  delivered by the Depositor.

            Every co-trustee or separate trustee shall, to the extent permitted
  by law, but to such extent only, be appointed subject to the following terms,
  namely:

            (a)  The Trust Securities shall be executed and delivered and
       all rights, powers, duties and obligations hereunder in respect of the
       custody of securities, cash and other personal property held by, or
       required to be deposited or pledged with, the Trustees specified
       hereunder, shall be exercised, solely by such Trustees and not by such
       co-trustee or separate trustee.

            (b)  The rights, powers, duties and obligations hereby
       conferred or imposed upon the Property Trustee in respect of any property
       covered by such appointment

                                      49


<PAGE>
 
       shall be conferred or imposed upon and exercised or performed by the
       Property Trustee or by the Property Trustee and such co-trustee or
       separate trustee jointly, as shall be provided in the instrument
       appointing such co-trustee or separate trustee, except to the extent that
       under any law of any jurisdiction in which any particular act is to be
       performed, the Property Trustee shall be incompetent or unqualified to
       perform such act, in which event such rights, powers, duties and
       obligations shall be exercised and performed by such co-trustee or
       separate trustee.

            (c)  The Property Trustee at any time, by an instrument in
       writing executed by it, with the written concurrence of the Depositor,
       may accept the resignation of or remove any co-trustee or separate
       trustee appointed under this Section, and, in case a Debenture Event of
       Default has occurred and is continuing, the Property Trustee shall have
       power to accept the resignation of, or remove, any such co-trustee or
       separate trustee without the concurrence of the Depositor.  Upon the
       written request of the Property Trustee, the Depositor shall join with
       the Property Trustee in the execution, delivery and performance of all
       instruments and agreements necessary or proper to effectuate such
       resignation or removal.  A successor to any co-trustee or separate
       trustee so resigned or removed may be appointed in the manner provided in
       this Section.

            (d)  No co-trustee or separate trustee hereunder shall be
       personally liable by reason of any act or omission of the Property
       Trustee or any other trustee hereunder.

            (e)  The Property Trustee shall not be liable by reason of any
       act of a co-trustee or separate trustee.

            (f)  Any Act of Holders delivered to the Property Trustee shall
       be deemed to have been delivered to each such co-trustee and separate
       trustee.

  SECTION 810.  Resignation and Removal; Appointment of Successor.
                ------------------------------------------------- 

            No resignation or removal of any Trustee (the "Relevant Trustee")
  and no appointment of a successor Trustee pursuant to this Article shall
  become effective until the acceptance of appointment by the successor Trustee
  in accordance with the applicable requirements of Section 811.

                                      50


<PAGE>
 
            Subject to the immediately preceding paragraph, the Relevant Trustee
  may resign at any time with respect to the Trust Securities by giving written
  notice thereof to the Securityholders.  If the instrument of acceptance by the
  successor Trustee required by Section 811 shall not have been delivered to the
  Relevant Trustee within 30 days after the giving of such notice of
  resignation, the Relevant Trustee may petition, at the expense of the Company,
  any court of competent jurisdiction for the appointment of a successor
  Relevant Trustee with respect to the Trust Securities.

            Unless a Debenture Event of Default shall have occurred and be
  continuing, any Trustee may be removed at any time by Act of the Common
  Securityholder.  If a Debenture Event of Default shall have occurred and be
  continuing, the Property Trustee or the Delaware Trustee, or both of them, may
  be removed at such time by Act of the Holders of a majority in Liquidation
  Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
  individual capacity and on behalf of the Trust).  An Administrative Trustee
  may be removed by the Common Securityholder at any time.

            If any Trustee shall resign, be removed or become incapable of
  acting as Trustee, or if a vacancy shall occur in the office of any Trustee
  for any cause, at a time when no Debenture Event of Default shall have
  occurred and be continuing, the Common Securityholder, by Act of the Common
  Securityholder delivered to the retiring Trustee, shall promptly appoint a
  successor Trustee or Trustees with respect to the Trust Securities and the
  Trust, and the successor Trustee shall comply with the applicable requirements
  of Section 811.  If the Property Trustee or the Delaware Trustee shall resign,
  be removed or become incapable of continuing to act as the Property Trustee or
  the Delaware Trustee, as the case may be, at a time when a Debenture Event of
  Default shall have occurred and be continuing, the Preferred Securityholders,
  by Act of the Securityholders of a majority in Liquidation Amount of the
  Preferred Securities then Outstanding delivered to the retiring Relevant
  Trustee, shall promptly appoint a successor Relevant Trustee or Trustees with
  respect to the Trust Securities and the Trust, and such successor Trustee
  shall comply with the applicable requirements of Section 811.  If an
  Administrative Trustee shall resign, be removed or become incapable of acting
  as Administrative Trustee, at a time when a Debenture Event of Default shall
  have occurred and be continuing, the Common Securityholder, by Act of the
  Common Securityholder delivered to the Administrative Trustee, shall promptly
  appoint a successor Administrative

                                      51


<PAGE>
 
  Trustee or Administrative Trustees with respect to the Trust Securities and
  the Trust, and such successor Administrative Trustee or Administrative
  Trustees shall comply with the applicable requirements of Section 811. If no
  successor Relevant Trustee with respect to the Trust Securities shall have
  been so appointed by the Common Securityholder or the Preferred
  Securityholders and accepted appointment in the manner required by Section
  811, any Securityholder who has been a Securityholder of Trust Securities for
  at least six months may, on behalf of himself and all others similarly
  situated, petition any court of competent jurisdiction for the appointment of
  a successor Relevant Trustee with respect to the Trust Securities.

            The Property Trustee shall give notice of each resignation and each
  removal of a Trustee and each appointment of a successor Trustee to all
  Securityholders in the manner provided in Section 1008 and shall give notice
  to the Depositor.  Each notice shall include the name of the successor
  Relevant Trustee and the address of its Corporate Trust Office if it is the
  Property Trustee.

            Notwithstanding the foregoing or any other provision of this Trust
  Agreement, in the event any Administrative Trustee or a Delaware Trustee who
  is a natural person dies or becomes, in the opinion of the Depositor,
  incompetent or incapacitated, the vacancy created by such death, incompetence
  or incapacity may be filled by (a) the unanimous act of remaining
  Administrative Trustees if there are at least two of them or (b) otherwise by
  the Depositor (with the successor in each case being a Person who satisfies
  the eligibility requirement for Administrative Trustees set forth in Section
  807).

  SECTION 811.  Acceptance of Appointment by Successor.
                -------------------------------------- 

            In case of the appointment hereunder of a successor Trustee such
  successor Trustee so appointed shall execute, acknowledge and deliver to the
  Trust and to the retiring Trustee an instrument accepting such appointment,
  and thereupon the resignation or removal of the retiring Trustee shall become
  effective and such successor Trustee, without any further act, deed or
  conveyance, shall become vested with all the rights, powers, trusts and duties
  of the retiring Trustee; but, on the request of the Depositor or the successor
  Trustee, such retiring Trustee shall, upon payment of its charges, execute and
  deliver an instrument transferring to such successor Trustee all the rights,
  powers and trusts of the retiring Trustee and if the Property Trustee is the
  resigning Trustee shall duly assign,

                                      52


<PAGE>
 
  transfer and deliver to the successor Trustee all property and money held by
  such retiring Property Trustee hereunder.

            In case of the appointment hereunder of a successor Relevant Trustee
  with respect to the Trust Securities and the Trust, the retiring Relevant
  Trustee and each successor Relevant Trustee with respect to the Trust
  Securities shall execute and deliver an amendment hereto wherein each
  successor Relevant Trustee shall accept such appointment and which (a) shall
  contain such provisions as shall be necessary or desirable to transfer and
  confirm to, and to vest in, each successor Relevant Trustee all the rights,
  powers, trusts and duties of the retiring Relevant Trustee with respect to the
  Trust Securities and the Trust and (b) shall add to or change any of the
  provisions of this Trust Agreement as shall be necessary to provide for or
  facilitate the administration of the trusts hereunder by more than one
  Relevant Trustee, it being understood that nothing herein or in such amendment
  shall constitute such Relevant Trustees co-trustees of the same trust and that
  each such Relevant Trustee shall be trustee of a trust or trusts hereunder
  separate and apart from any trust or trusts hereunder administered by any
  other such Relevant Trustee and upon the execution and delivery of such
  amendment the resignation or removal of the retiring Relevant Trustee shall
  become effective to the extent provided therein and each such successor
  Relevant Trustee, without any further act, deed or conveyance, shall become
  vested with all the rights, powers, trusts and duties of the retiring Relevant
  Trustee with respect to the Trust Securities and the Trust; but, on request of
  the Trust or any successor Relevant Trustee such retiring Relevant Trustee
  shall duly assign, transfer and deliver to such successor Relevant Trustee all
  Trust Property, all proceeds thereof and money held by such retiring Relevant
  Trustee hereunder with respect to the Trust Securities and the Trust.

            Upon request of any such successor Relevant Trustee, the Trust shall
  execute any and all instruments for more fully and certainly vesting in and
  confirming to such successor Relevant Trustee all such rights, powers and
  trusts referred to in the first or second preceding paragraph, as the case may
  be.

            No successor Relevant Trustee shall accept its appointment unless at
  the time of such acceptance such successor Relevant Trustee shall be qualified
  and eligible under this Article.

  SECTION 812.  Merger, Conversion, Consolidation or Succession to Business.
                ----------------------------------------------------------- 

            Any corporation into which the Property Trustee or the Delaware
  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 such Relevant Trustee shall be a party, or any corporation succeeding to
  all or substantially all the corporate trust business of such Relevant
  Trustee, shall be the successor of such Relevant Trustee hereunder, provided
  such corporation shall be otherwise qualified and eligible under this Article,
  without the execution or filing of any paper or any further act on the part of
  any of the parties hereto.

  SECTION 813.  Preferential Collection of Claims Against Depositor or Trust.
                ------------------------------------------------------------ 

            If and when the Property Trustee or the Delaware Trustee shall be or
  become a creditor of the Depositor or the Trust (or any other obligor upon the
  Debentures or the Trust Securities), the Property Trustee or the Delaware
  Trustee, as the case may be, shall be subject to and shall take all actions
  necessary in order to comply with the provisions of the Trust Indenture Act
  regarding the collection of claims against the Depositor or Trust (or any such
  other obligor).

  SECTION 814.  Reports by Property Trustee.
                --------------------------- 

            (a)  Not later than July 15 of each year commencing with July 15,
  1997, the Property Trustee shall transmit to all Securityholders in accordance
  with Section 1008, and to the Depositor, a brief report dated as of such
  December 31 with respect to:

            (i)  its eligibility under Section 807 or, in lieu thereof,
       if to the best of its knowledge it has continued to be eligible under
       said Section, a written statement to such effect;

            (ii)  a statement that the Property Trustee has complied with
       all of its obligations under this Trust Agreement during the twelve-month
       period (or, in the case of the initial report, the period since the
       Closing Date) ending with such December 31 or, if the Property Trustee
       has not complied in any material respect with such obligations, a
        description of such noncompliance; and

                                      54


<PAGE>
 
          (iii) any change in the property and funds in its possession
       as Property Trustee since the date of its last report and any action
       taken by the Property Trustee in the performance of its duties hereunder
       which it has not previously reported and which in its opinion materially
       affects the Trust Securities.


            (b) In addition, the Property Trustee shall transmit to
  Securityholders such reports concerning the Property Trustee and its actions
  under this Trust Agreement as may be required pursuant to the Trust Indenture
  Act at the times and in the manner provided pursuant thereto.

            (c) A copy of each such report shall, at the time of such
  transmission to Holders, be filed by the Property Trustee with each national
  securities exchange, the Nasdaq National Market or such other interdealer
  quotation system or self-regulatory organization upon which the Trust
  Securities are listed or traded, with the Commission and with the Depositor.

  SECTION 815.  Reports to the Property Trustee.

  in the form, in the manner and at the times required by Section 314 of the

  accordance with Section 810.

            (c)  The death, resignation, retirement, removal, bankruptcy,

  operate to annul the Trust.  Whenever a vacancy in the number of
  Administrative Trustees shall occur, until such vacancy is filled by the

            The first to occur of any of the following events is an "Early
  Termination Event":

            (a)  the occurrence of a Bankruptcy Event in respect of, or the
       dissolution or liquidation of, the Depositor;

            (b)  the written direction to the Property Trustee from the
       Depositor at any time (which direction is optional and wholly within the
       discretion of the Depositor) to terminate the Trust and distribute the
       Debentures in exchange for the Preferred Securities;

            (c)  the redemption of all of the Preferred Securities in
       connection with the redemption of all of the Debentures; and

            (d)  the entry of an order for dissolution of the Trust by a
       court of competent jurisdiction.

  SECTION 903.  Termination.
                ----------- 

            The respective obligations and responsibilities of the Trustees and
  the Trust created and continued hereby shall terminate upon the latest to
  occur of the following:  (a) the distribution by the Property Trustee to
  Securityholders upon the liquidation of the Trust pursuant to Section 904, or
  upon the redemption of all of the Trust Securities pursuant to Section 402, of
  all amounts required to be distributed hereunder upon the final payment of the
  Trust Securities; (b) the payment of any expenses owed by the Trust; and (c)
  the discharge of all administrative duties of the Administrative Trustees,
  including the performance of any tax reporting obligations with respect to the
  Trust or the Securityholders.

  SECTION 904.  Liquidation.
                ----------- 

            (a)  If an Early Termination Event specified in clause (a), (b)
     or (d) of Section 902 occurs or upon the Expiration Date, the Trust shall
     be liquidated by the Trustees as expeditiously as the Trustees determine to
     be possible by distributing, after satisfaction of liabilities to creditors
     of the Trust as provided by applicable law, to each Securityholder a Like
     Amount of Debentures, subject to Section 904(d).  Notice of liquidation
     shall be given by the Property Trustee by first-class mail, postage
     prepaid, mailed not later than 30 nor more than 60 days prior to the
     Liquidation Date to each Holder of Trust Securities at such

                                      57


<PAGE>
 
     Holder's address appearing in the Securities Register. All notices of
     liquidation shall:

              (i)  state the Liquidation Date;
                   --------------------------

             (ii)  state that from and after the Liquidation Date, the
       Trust Securities will no longer be deemed to be Outstanding and any Trust
       Securities Certificates not surrendered for exchange will be deemed to
       represent a Like Amount of Debentures; and

            (iii)   provide such information with respect to the mechanics by
       which Holders may exchange Trust Securities Certificates for Debentures,
       or if Section 904(d) applies receive a Liquidation Distribution, as the
       Administrative Trustees or the Property Trustee shall deem appropriate.
      
              (b)  Except where Section 902(c) or 904(d) applies, in order to
     effect the liquidation of the Trust and distribution of the Debentures to
     Securityholders, the Property Trustee shall establish a record date for
     such distribution (which shall be not more than 45 days prior to the
     Liquidation Date) and, either itself acting as exchange agent or through
     the appointment of a separate exchange agent, shall establish such
     procedures as it shall deem appropriate to effect the distribution of
     Debentures in exchange for the Outstanding Trust Securities Certificates.

              (c)  Except where Section 902(c) or 904(d) applies, after the
     Liquidation Date, (i) the Trust Securities will no longer be deemed to be
     Outstanding, (ii) certificates representing a Like Amount of Debentures
     will be issued to holders of Trust Securities Certificates, upon surrender
     of such certificates to the Administrative Trustees or their agent for
     exchange, (iii) the Depositor shall use its reasonable efforts to have the
     Debentures listed on the New York Stock Exchange or on such other stock
     exchange, interdealer quotation system or self-regulatory organization as
     the Preferred Securities are then listed or traded, (iv) any Trust
     Securities Certificates not so surrendered for exchange will be deemed to
     represent a Like Amount of Debentures, accruing interest at the rate
     provided for in the Debentures from the last Distribution Date on which a
     Distribution was made on such Trust Securities Certificates until such
     certificates are so surrendered (and until such certificates are so
     surrendered, no payments of interest or principal will be made to holders
     of Trust Securities Certificates with respect to such Debentures), and (v)
     all rights of Securityholders holding Trust Securities will cease, except
     the right of such 

                                      58


<PAGE>
 
     Securityholders to receive Debentures upon surrender of Trust Securities
     Certificates.

            (d)  In the event that, notwithstanding the other provisions of
     this Section 904, whether because of an order for dissolution entered by a
     court of competent jurisdiction or otherwise, distribution of the
     Debentures in the manner provided herein is determined by the Property
     Trustee not to be practical, the Trust Property shall be liquidated, and
     the Trust shall be dissolved, wound-up or terminated, by the Property
     Trustee in such manner as the Property Trustee determines.  In such event,
     on the date of the dissolution, winding-up or other termination of the
     Trust, Securityholders will be entitled to receive out of the assets of the
     Trust available for distribution to Securityholders, after satisfaction of
     liabilities to creditors of the Trust as provided by applicable law, an
     amount equal to the Liquidation Amount per Trust Security plus accumulated
     and unpaid Distributions thereon to the date of payment (such amount being
     the "Liquidation Distribution").  If, upon any such dissolution, winding-up
     or termination, the Liquidation Distribution can be paid only in part
     because the Trust has insufficient assets available to pay in full the
     aggregate Liquidation Distribution, then, subject to the next succeeding
     sentence, the amounts payable by the Trust on the Trust Securities shall be
     paid on a pro rata basis (based upon Liquidation Amounts).  The holder of
     the Common Securities will be entitled to receive Liquidation Distributions
     upon any such dissolution, winding-up or termination pro rata (determined
     as aforesaid) with Holders of Preferred Securities, except that, if a
     Debenture Event of Default has occurred and is continuing, the Preferred
     Securities shall have a priority over the Common Securities.

     SECTION 905.  Mergers, Consolidations, Amalgamations or Replacements of
                   --------------------------------------------------------- 
                   the Trust.  
                   --------- 

            The Trust may not merge with or into, consolidate, amalgamate, or be
  replaced by, or convey, transfer or lease its properties and assets
  substantially as an entirety to any corporation or other body, except pursuant
  to this Section 905.  At the request of the Depositor, with the consent of the
  Administrative Trustees and without the consent of the holders of the
  Preferred Securities, the Trust may merge with or into, consolidate,
  amalgamate, or be replaced by or convey, transfer or lease its properties and
  assets substantially as an entirety to a trust organized as such under the
  laws of any state; provided, that (i) such successor entity either (a)
                     --------                                           
  expressly assumes all of the obligations of the Trust with respect to the
  Preferred 

                                      59


<PAGE>
 
  Securities or (b) substitutes for the Preferred Securities other
  securities having substantially the same terms as the Preferred Securities
  (the "Successor Securities") so long as the Successor Securities rank the same
  as the Preferred Securities rank in priority with respect to distributions and
  payments upon liquidation, redemption and otherwise, (ii) the Depositor
  expressly appoints a trustee of such successor entity possessing the same
  powers and duties as the Property Trustee as the holder of the Debentures,
  (iii) the Successor Securities are listed or traded, or any Successor
  Securities will be listed upon notification of issuance, on any national
  securities exchange or other organization on which the Preferred Securities
  are then listed or traded, if any, (iv) such merger, consolidation,
  amalgamation, replacement, conveyance, transfer or lease does not cause the
  Preferred Securities (including any Successor Securities) to be downgraded by
  any nationally recognized statistical rating organization, (v) such merger,
  consolidation, amalgamation, replacement, conveyance, transfer or lease does
  not adversely affect the rights, preferences and privileges of the holders of
  the Preferred Securities (including any Successor Securities) in any material
  respect, (vi) such successor entity has a purpose identical to that of the
  Trust, (vii) prior to such merger, consolidation, amalgamation, replacement,
  conveyance, transfer or lease, the Depositor has received an Opinion of
  Counsel to the effect that (a) such merger, consolidation, amalgamation,
  replacement, conveyance, transfer or lease does not adversely affect the
  rights, preferences and privileges of the holders of the Preferred Securities
  (including any Successor Securities) in any material respect, and (b)
  following such merger, consolidation, amalgamation, replacement, conveyance,
  transfer or lease, neither the Trust nor such successor entity will be
  required to register as an investment company under the 1940 Act and (viii)
  the Depositor owns all of the Common Securities of such successor entity and
  guarantees the obligations of such successor entity under the Successor
  Securities at least to the extent provided by the Guarantee.  Notwithstanding
  the foregoing, the Trust shall not, except with the consent of holders of 100%
  in Liquidation Amount of the Preferred Securities, consolidate, amalgamate,
  merge with or into, be replaced by or convey, transfer or lease its properties
  and assets substantially as an entirety to any other entity or permit any
  other entity to consolidate, amalgamate, merge with or into, or replace it if
  such consolidation, amalgamation, merger, replacement, conveyance, transfer or
  lease would cause the Trust or the successor entity to be classified as other
  than a grantor trust for United States federal income tax purposes.

            The death or incapacity of any person having an interest, beneficial

  bring any proceeding in any court for a partition or winding-up of the
  arrangements contemplated hereby, nor otherwise affect the rights, obligations
  and liabilities of the parties hereto or any of them.

     Agreement, which shall not be inconsistent with the other provisions of

     of this Trust Agreement to such extent as shall be necessary to ensure that
     the Trust will be classified for United States federal income tax purposes
     as a grantor trust at all times that any Trust Securities are outstanding
     or to ensure that the Trust will not be required to register as an
     investment company under the 1940 Act; provided, however, that in the case

     Outstanding and (ii) receipt by the Trustees of an Opinion of Counsel to
     the effect that such amendment or the exercise of any power granted to the

     the Trust's exemption from status of an investment company under the 1940
     Act.

     (such consent being obtained in accordance with Section 603 or 606 hereof),
     this Trust Agreement may not be amended to (i) change the amount or timing
     of any Distribution on the Trust Securities or otherwise adversely affect
     the amount of any Distribution required to be made in respect of the Trust
     Securities as of a specified date or (ii) restrict the right of a

     fail or cease to be classified as a grantor trust for United States federal
     income tax purposes.

            (e)  Notwithstanding anything in this Trust Agreement to the

     made, the Administrative Trustees shall promptly provide to the Depositor a
     copy of such amendment.

Re:  MCI Capital IV ____% Cumulative Quarterly Income Preferred Securities,
     ----------------------------------------------------------------------
     Series A
     --------


Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the MCI
Capital IV ___% Cumulative Quarterly Income Preferred Securities, Series A (the
"Preferred Securities"), of MCI Capital IV, a Delaware business trust (the
"Issuer"), formed pursuant to a Trust Agreement between MCI Communications
Corporation ("MCI") and Wilmington Trust Company, as Trustee.  The payment of
distributions on the Preferred Securities and payments due upon liquidation of
Issuer or redemption of the Preferred Securities, to the extent the Issuer has
funds available for the payment thereof, are guaranteed by MCI to the extent set
forth in a Guarantee Agreement dated ________ __, 1996 by MCI with respect to
the Preferred Securities.  MCI and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement dated _________ __, 1996 by and among the Underwriters,
the Issuer and MCI, and the Underwriters wish to take delivery of the Preferred
Securities through DTC. Wilmington Trust Company is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:


     1.  Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about ________ __, 1996, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") 

                                       1

<PAGE>
 
registered in the name of DTC's Preferred Securities nominee, Cede & Co.,
representing an aggregate of __________ Preferred Securities and bearing the
following legend:

     Unless this certificate is presented by an authorized representative of The
     Depository Trust Company, a New York corporation ("DTC"), to Issuer or its
     agent for registration of transfer, exchange, or payment, and any
     certificate issued is registered in the name of Cede & Co. or in such other
     name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
     HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
     the registered owner hereof, Cede & Co., has an interest herein.

     2.  The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances.  The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

     3.  In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4.  In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying:  (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means 
(e.g., legible telecopy, registered or certified mail, overnight delivery) in a

                                       2

timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before the Publication
Date. The Issuer or the Transfer Agent and Registrar will forward such notice
either in a separate secure transmission for each CUSIP number or in a secure
transmission of multiple CUSIP numbers (if applicable) that includes a manifest
or list of each CUSIP number submitted in that transmission. (The party sending
such notice shall have a method to verify subsequently the use of such means and
the timeliness Of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.

Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4.  Such redemption notice shall be
sent to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190,
and receipt of such notice shall be confirmed by telephoning (516) 227-4070.

     8.  Distribution payments or other cash payments with respect to the

Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion:  

                                       4

countersign a new Global Certificate; or (b) may make an appropriate notation on
the Global Certificate indicating the date and amount of such reduction.

     11.  DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law.  Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any

Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates.  In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13.  This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such

     transfer this Guarantee Agreement to any Person except a Holder exercising
     his or her rights pursuant to Section 504(iv) or to a Successor Guarantee

     Default has occurred (that has not been cured or waived pursuant to Section
     206), the Guarantee Trustee shall exercise such of the rights and powers
     vested in it by this Guarantee Agreement, and use the same degree of care
     and skill in its exercise thereof, as a prudent person would exercise or
     use under the circumstances in the conduct of his or her own affairs.

          (d)  No provision of this Guarantee Agreement shall be construed to
     relieve the Guarantee Trustee from liability for its own negligent action,
     its own negligent failure to act or its own willful misconduct, except
     that:

               (i)  prior to the occurrence of any Event of Default and after
          the curing or waiving of all such Events of Default that may have
          occurred:

                    (A)  the duties and obligations of the Guarantee Trustee

               as are specifically set forth in this Guarantee Agreement; and

                    (B)  in the absence of bad faith on the part of the

               as to the truth of the statements and the correctness of the
               opinions expressed therein, upon any certificates or opinions
               furnished to the Guarantee Trustee and conforming to the
               requirements of this Guarantee Agreement; but in the case of any
               such certificates or opinions that by any provision hereof or of
               the Trust Indenture Act are specifically required to be furnished
               to the Guarantee Trustee, the Guarantee Trustee shall be under a
               duty to examine the same to determine whether or not they conform
               to the requirements of this Guarantee Agreement;

          judgment made in good faith by a Responsible Officer of the Guarantee
          Trustee, unless it shall be proved that the Guarantee Trustee was
          negligent in ascertaining the pertinent facts upon which such judgment
          was made;

              (iii)  the Guarantee Trustee shall not be liable with respect to

          Majority in liquidation preference of the Preferred Securities
          relating to the time, method and place of conducting any proceeding
          for any remedy available to the Guarantee Trustee, or exercising any
          trust or power conferred upon the Guarantee Trustee under this
          Guarantee Agreement; and

               (iv)  no provision of this Guarantee Agreement shall require the
          Guarantee Trustee to expend or risk its own funds or otherwise incur
          personal financial liability in the performance of any of its duties
          or in the exercise of any of its rights or powers, if the Guarantee
          Trustee shall have reasonable grounds for believing that the repayment
          of such funds or liability is not reasonably assured to it under the
          terms of this Guarantee Agreement or adequate indemnity against such
          risk or liability is not reasonably assured to it.

          herein specifically prescribed) may, in the absence of bad faith on
          its part, request and rely upon an Officers' Certificate which, upon

          exercise any of the rights or powers vested in it by this Guarantee
          Agreement at the request or direction of any Holder, unless such

          security and indemnity as would satisfy a reasonable person in the
          position of the Guarantee Trustee, against the costs, expenses
          (including attorneys' fees and expenses) and liabilities that might be
          incurred by it in complying with such request or direction, including

law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement.  If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 503 hereof.

     use under the circumstances in the conduct of his or her own affairs.

          (d)  No provision of this Guarantee Agreement shall be construed to

               requirements of this Guarantee Agreement; but in the case of any
               such certificates or opinions that by any provision hereof or of
               the Trust Indenture Act are specifically required to be furnished
               to the Guarantee Trustee, the Guarantee Trustee shall be under a
               duty to examine the same to determine whether or not they conform
               to the requirements of this Guarantee Agreement;

          judgment made in good faith by a Responsible Officer of the Guarantee

          relating to the time, method and place of conducting any proceeding
          for any remedy available to the Guarantee Trustee, or exercising any
          trust or power conferred upon the Guarantee Trustee under this
          Guarantee Agreement; and

          Trustee shall have reasonable grounds for believing that the repayment
          of such funds or liability is not reasonably assured to it under the
          terms of this Guarantee Agreement or adequate indemnity against such
          risk or liability is not reasonably assured to it.

          (a)  There shall at all times be a Guarantee Trustee which shall:

               (i)  not be an Affiliate of the Guarantor; and

               (ii)  be a Person that is eligible pursuant to the Trust

          corporation publishes reports of condition at least annually, pursuant
          to law or to the requirements of the supervising or examining
          authority, then, for the purposes of this Section and to the extent
          permitted by the Trust Indenture Act, the combined capital and surplus
          of such corporation shall be deemed to be its combined capital and
          surplus as set forth in its most recent report of condition so
          published.

               (b) If at any time the Guarantee Trustee shall cease to be

          (c) If the Guarantee Trustee has or shall acquire any "conflicting
     interest" within the meaning of Section 310(b) of the Trust Indenture Act,
     the Guarantee Trustee and Guarantor shall in all respects comply with the
     provisions of Section 310(b) of the Trust Indenture Act.

     Guarantee Trustee has been appointed and has accepted such appointment by
     written instrument executed by such Successor Guarantee Trustee and
     delivered to the Guarantor.

          (c)  The Guarantee Trustee appointed hereunder shall hold office until

     (without need for prior or subsequent accounting) by an instrument in
     writing executed by the Guarantee Trustee and delivered to the Guarantor,
     which resignation shall not take effect until a Successor Guarantee Trustee
     has been appointed and has accepted such appointment by instrument in
     writing executed by such Successor Guarantee Trustee and delivered to the
     Guarantor and the resigning Guarantee Trustee.

          (d)  If no Successor Guarantee Trustee shall have been appointed and
     accepted appointment as provided in this Section 402 within 60 days after
     delivery to the Guarantor of an instrument of resignation, the resigning
     Guarantee Trustee may petition, at the expense of the Guarantor, any court
     of competent jurisdiction for appointment of a Successor Guarantee Trustee.
     Such court may thereupon, after prescribing such notice, if any, as it may
     deem proper, appoint a Successor Guarantee Trustee.

     agreement, covenant, term or condition relating to the Preferred Securities
     to be performed or observed by the Issuer;

     intent of this Section 503 that the obligations of the Guarantor hereunder
     shall be absolute and unconditional under any and all circumstances.

as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement.  If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

               ------------------------------------------ 

          (a)  This Guarantee Agreement shall be held by the Guarantee Trustee
     for the benefit of the Holders, and the Guarantee Trustee shall not
     transfer this Guarantee Agreement to any Person except a Holder exercising
     his or her rights pursuant to Section 504(iv) or to a Successor Guarantee
     Trustee on acceptance by such Successor Guarantee Trustee of its
     appointment to act as Successor Guarantee Trustee.  The right, title and
     interest of the Guarantee Trustee shall automatically vest in any Successor
     Guarantee Trustee, upon acceptance by such Successor Guarantee Trustee of

     undertake to perform only such duties as are specifically set forth in this
     Guarantee Agreement, and no implied covenants shall be read into this
     Guarantee Agreement against the Guarantee Trustee.  In case an Event of
     Default has occurred (that has not been cured or waived pursuant to Section
     206), the Guarantee Trustee shall exercise such of the rights and powers
     vested in it by this Guarantee Agreement, and use the same degree of care
     and skill in its exercise thereof, as a prudent person would exercise or
     use under the circumstances in the conduct of his or her own affairs.

          (d)  No provision of this Guarantee Agreement shall be construed to
     relieve the Guarantee Trustee from liability for its own negligent action,
     its own negligent failure to act or its own willful misconduct, except
     that:

               (i)  prior to the occurrence of any Event of Default and after

               opinions expressed therein, upon any certificates or opinions
               furnished to the Guarantee Trustee and conforming to the
               requirements of this Guarantee Agreement; but in the case of any
               such certificates or opinions that by any provision hereof or of
               the Trust Indenture Act are specifically required to be furnished
               to the Guarantee Trustee, the Guarantee Trustee shall be under a
               duty to examine the same to determine whether or not they conform

          judgment made in good faith by a Responsible Officer of the Guarantee

          relating to the time, method and place of conducting any proceeding

          personal financial liability in the performance of any of its duties
          or in the exercise of any of its rights or powers, if the Guarantee

          terms of this Guarantee Agreement or adequate indemnity against such
          risk or liability is not reasonably assured to it.

               (ii)  Any direction or act of the Guarantor contemplated by this
          Guarantee Agreement shall be

                                     -10-
<PAGE>
 
          sufficiently evidenced by an Officers' Certificate unless otherwise
          prescribed herein.

               (iii)  Whenever, in the administration of this Guarantee
          Agreement, the Guarantee Trustee shall deem it desirable that a matter
          be proved or established before taking, suffering or omitting to take
          any action hereunder, the Guarantee Trustee (unless other evidence is
          herein specifically prescribed) may, in the absence of bad faith on
          its part, request and rely upon an Officers' Certificate which, upon
          receipt of such request from the Guarantee Trustee, shall be promptly
          delivered by the Guarantor.

               (iv)  The Guarantee Trustee may consult with legal counsel, and

          exercise any of the rights or powers vested in it by this Guarantee
          Agreement at the request or direction of any Holder, unless such

          security and indemnity as would satisfy a reasonable person in the
          position of the Guarantee Trustee, against the costs, expenses
          (including attorneys' fees and expenses) and liabilities that might be
          incurred by it in complying with such request or direction, including
          such reasonable advances as may be requested by the Guarantee Trustee;
          provided that, nothing contained in this Section 302(a)(v) shall be
          taken to relieve the Guarantee Trustee, upon the occurrence of an
          Event of Default, of its obligation to exercise the rights and powers
          vested in it by this Guarantee Agreement.

          direction, consent, order, bond, debenture, note, other evidence of
          indebtedness or other paper or document, but the Guarantee Trustee, in

          Agreement the Guarantee Trustee shall deem it desirable to receive

          any other action hereunder, the Guarantee Trustee (A) may request

     or exercise any right, power, duty or obligation conferred or imposed on it
     in any jurisdiction in which it shall be illegal, or in which the Guarantee
     Trustee shall be unqualified or incompetent in accordance with applicable
     law, to perform any such act or acts or to exercise any such right, power,

faith on the part of the Guarantee Trustee, arising out of or in connection with

          corporation publishes reports of condition at least annually, pursuant

          permitted by the Trust Indenture Act, the combined capital and surplus
          of such corporation shall be deemed to be its combined capital and
          surplus as set forth in its most recent report of condition so
          published.

               (b) If at any time the Guarantee Trustee shall cease to be

     provisions of Section 310(b) of the Trust Indenture Act.

     delivered to the Guarantor.
