   Contract Agent as provided in Section 5.4(a)(i) of the Purchase
   Contract Agreement of its intention to pay the Purchase Price in cash,
   but fails to make such payment as required by Section 5.4(a)(ii) of
   the Purchase Contract Agreement, such Holder shall be deemed to have
   consented to the disposition of the Pledged Debentures of such Holder

                                     13




   in accordance with Section 5.4(a)(iii) of the Purchase Contract
   Agreement.

             (c)  If a Holder of a Treasury Unit notifies the Purchase

             SECTION 5.6.   [INTENTIONALLY OMITTED].

             SECTION 5.7.   APPLICATION OF PROCEEDS OF SETTLEMENT.

             (a)  If a Holder of Corporate Units has not elected to make
   an effective Cash Settlement by notifying the Purchase Contract Agent
   in the manner provided for in Section 5.4(a)(i) in the Purchase
   Contract Agreement, or has given such notice but failed to deliver the
   required cash to the Securities Intermediary prior to 11:00 A.M., New
   York City time, on the fifth Business Day immediately preceding the
   Purchase Contract Settlement Date, such Holder shall be deemed to have
   elected to pay for the shares of Common Stock to be issued under such
   Purchase Contract(s) from the Proceeds of the related Pledged
   Debentures.  In such event, the Collateral Agent shall instruct the
   Securities Intermediary to Transfer the related Pledged Debentures to
   the Remarketing Agent for remarketing.  Upon receiving such Pledged
   Debentures, the Remarketing Agent, pursuant to the terms of the
   Remarketing Agreement, will use commercially reasonable efforts to
   remarket such Pledged Debentures on such date at a price of 100.50% of
   the aggregate principal amount of such Pledged Debentures.  From the
   proceeds of the Remarketing, the Remarketing Agent will retain an
   amount (not exceeding 0.50% of the aggregate principal amount of such
   Pledged Debentures) equal to its remarketing fee and will deposit the
   remaining amount of the Proceeds of such remarketing in the Collateral
   Account.  On the Purchase Contract Settlement Date, the Collateral
   Agent shall instruct the Securities Intermediary to apply a portion of
   the Proceeds from such remarketing equal to the aggregate principal

                                     14






   amount of such Pledged Debentures to satisfy in full the obligations
   of such Holders of Corporate Units to pay the Purchase Price to
   purchase the Common Stock under the related Purchase Contracts.  The
   balance of the Proceeds from such remarketing (if any) shall be
   transferred to the Company.  If the Remarketing Agent advises the
   Collateral Agent in writing that there has been a Failed Remarketing,
   the Collateral Agent, for the benefit of the Company shall, at the
   written direction of the Company, dispose of the Pledged Debentures in
   accordance with applicable law and satisfy in full, from such
   disposition, such Holders' obligations to pay the Purchase Price for
   the Common Stock.

             (b)  If a Holder of Treasury Units has not elected to make
   an effective cash settlement by notifying the Purchase Contract Agent
   in the manner provided for in Section 5.4(d)(i) of the Purchase
   Contract Agreement, or has given such notice but failed to make such
   payment in the manner required by Section 5.4(d)(ii) of the Purchase
   Contract Agreement, such Holder shall be deemed to have elected to pay
   for the shares of Common Stock to be issued under such Purchase
   Contract(s) from the Proceeds of the related Pledged Treasury
   Securities.  Upon maturity of the Pledged Treasury Securities, the
   Securities Intermediary, at the written direction of the Collateral
   Agent, shall invest the Cash Proceeds of the maturing Pledged Treasury
   Securities in Permitted Investments of the type described in clause
   (vi) of the definition thereof unless it has received other
   instructions from the Company by 10:30 a.m., New York time, on such
   date.  Without receiving any instruction from any such Holder of
   Treasury Units, the Collateral Agent shall apply the Proceeds of the
   related Pledged Treasury Securities to the settlement of such Purchase
   Contracts on the Purchase Contract Settlement Date.  If the sum of the
   Proceeds from the related Pledged Treasury Securities and the
   investment earnings from the investment in Permitted Investments is in
   excess of the aggregate Purchase Price of the Purchase Contracts being
   settled, the Collateral Agent shall instruct the Securities
   Intermediary to distribute such excess, when received, to the Purchase
   Contract Agent for the benefit of such Holders for distribution to
   such Holders in accordance with their respective interests.


                                 ARTICLE VI

                     VOTING RIGHTS - PLEDGED DEBENTURES

             The Purchase Contract Agent may exercise, or refrain from
   exercising, any and all voting and other consensual rights pertaining
   to the Pledged Debentures or any part of them in accordance with the
   terms of the Purchase Contract Agreement; PROVIDED, that the Purchase
   Contract Agent shall not exercise or, as the case may be, shall not
   refrain from exercising such right if, in the judgment of the Purchase
   Contract Agent, such action or inaction would impair or otherwise have
   a material and adverse effect on the value of all or any of the
   Pledged Debentures; and PROVIDED FURTHER, that the Purchase Contract

                                     15






   Agent shall give the Company and the Collateral Agent at least five
   days' prior written notice of the manner in which it intends to
   exercise, or its reasons for refraining from exercising, any such
   right.  Upon receipt of any notices and other communications in
   respect of any Pledged Debentures, including notice of any meeting at
   which holders of the Debentures are entitled to vote or solicitation
   of consents, waivers or proxies of holders of the Debentures, the
   Collateral Agent shall use reasonable efforts to send promptly to the
   Purchase Contract Agent such notice or communication, and as soon as
   reasonably practicable after receipt of a written request from the
   Purchase Contract Agent, shall execute and deliver to the Purchase
   Contract Agent such proxies and other instruments in respect of such
   Pledged Debentures (in form and substance satisfactory to the
   Collateral Agent) as are prepared by the Company and delivered to the
   Purchase Contract Agent with respect to the Pledged Debentures.


                                 ARTICLE VII

                            RIGHTS AND REMEDIES;
                       DISTRIBUTION OF THE DEBENTURES

             SECTION 7.1.   RIGHTS AND REMEDIES OF THE COLLATERAL AGENT.

             (a)  In addition to the rights and remedies specified in
   Section 5.4 or otherwise available at law or in equity, after an event
   of default (as specified in Section 7.1(b) below), the Collateral
   Agent shall have all of the rights and remedies with respect to the
   Collateral of a secured party under the Code (whether or not the Code
   is in effect in the jurisdiction where the rights and remedies are
   asserted) and the TRADES Regulations and such additional rights and
   remedies to which a secured party is entitled under the laws in effect
   in any jurisdiction where any rights and remedies under this Agreement
   may be asserted.  Without limiting the generality of the foregoing,
   such remedies may include, to the extent permitted by applicable law,
   (i) retention of the Pledged Debentures in full satisfaction of the
   Holders' obligations under the Purchase Contracts or (ii) sale of the
   Pledged Debentures in one or more public or private sales.

             (b)  Without limiting any rights or powers otherwise granted
   by this Agreement to the Collateral Agent, if the Collateral Agent is
   unable to make payments to the Company on account of principal
   payments of any Pledged Treasury Securities as provided in Article
   III, in satisfaction of the Obligations of the Holder of the Treasury
   Units of which such Pledged Treasury Securities is a part under the
   related Purchase Contracts, the inability to make such payments shall
   constitute an event of default under this Agreement and the Collateral
   Agent shall have and may exercise, with reference to such Pledged
   Treasury Securities and such Obligations of such Holder, any and all
   of the rights and remedies available to a secured party under the Code
   and the TRADES Regulations after default by a debtor, and as otherwise
   granted in this Agreement or under any other law.

                                     16






             (c)  Without limiting any rights or powers otherwise granted
   by this Agreement to the Collateral Agent, the Collateral Agent is
   irrevocably authorized to receive and collect all payments of (i) the
   principal amount of the Pledged Treasury Securities and (ii) the
   principal amount of the Pledged Debentures, subject, in each case, to
   the provisions of Article III, and as otherwise granted in this
   Agreement.

             (d)  The Purchase Contract Agent and each Holder of Units,
   in the event such Holder becomes the Holder of a Treasury Unit, agrees
   that, from time to time, upon the written request of the Collateral
   Agent, the Purchase Contract Agent or such Holder shall execute and
   deliver such further documents and do such other acts and things as
   the Collateral Agent may reasonably request in order to maintain the
   Pledge, and the perfection and priority of the Pledge, and to confirm
   the rights of the Collateral Agent under this Agreement.  The Purchase
   Contract Agent shall have no liability to any Holder for executing any
   documents or taking any such acts requested by the Collateral Agent
   under this Agreement, except for liability for its own negligent acts,
   its own negligent failure to act or its own willful misconduct.

             SECTION 7.2.   SUBSTITUTIONS.  Whenever a Holder has the
   right to substitute Treasury Securities, Debentures or security
   entitlements to either of them, as the case may be, for financial
   assets held in the Collateral Account, such substitution shall not
   constitute a novation of the security interest created by this
   Agreement.

                  REPRESENTATIONS AND WARRANTIES; COVENANTS

             SECTION 8.1.   REPRESENTATIONS AND WARRANTIES.  Each Holder
   from time to time, acting through the Purchase Contract Agent as
   attorney-in-fact (it being understood that the Purchase Contract Agent
   shall not be liable for any representation or warranty made by or on
   behalf of a Holder), represents and warrants to the Collateral Agent
   (with respect to his interest in the Collateral), which
   representations and warranties shall be deemed repeated on each day a
   Holder Transfers Collateral that:

             (a)  such Holder has the power to grant a security
                  interest in and lien on the Collateral;

             (b)  such Holder is the sole beneficial owner of the
                  Collateral and, in the case of Collateral
                  delivered in physical form, is the sole holder of
                  such Collateral and is the sole beneficial owner
                  of, or has the right to Transfer, the Collateral
                  it Transfers to the Securities Intermediary for
                  credit to the Collateral Account, free and clear

                                     17






                  of any security interest, lien, encumbrance, call,
                  liability to pay money or other restriction other
                  than the security interest and lien granted under
                  Article II;

             (c)  upon the Transfer of the Collateral to the
                  Securities Intermediary for credit to the
                  Collateral Account, the Collateral Agent, for the
                  benefit of the Company, will have a valid and
                  perfected first priority security interest in the
                  Collateral (assuming that any central clearing
                  operation or any securities intermediary or other
                  entity not within the control of the Holder in-
                  volved in the Transfer of the Collateral,
                  including the Collateral Agent and the Securities
                  Intermediary, gives the notices and takes the
                  action required of it under this Agreement and
                  under applicable law for perfection of that
                  interest and assuming the establishment and
                  exercise of control pursuant to Article IV); and

             (d)  the execution and performance by the Holder of its
                  obligations under this Agreement will not result
                  in the creation of any security interest, lien or
                  other encumbrance on the Collateral other than the
                  security interest and lien granted under Article
                  II or violate any provision of any existing law or
                  regulation applicable to it or of any mortgage,
                  charge, pledge, indenture, contract or undertaking
                  to which it is a party or which is binding on it
                  or any of its assets.

             SECTION 8.2.   COVENANTS.  The Holders from time to time,
   acting through the Purchase Contract Agent as their attorney-in-fact
   (it being understood that the Purchase Contract Agent shall not be
   liable for any covenant made by or on behalf of a Holder), covenant to
   the Collateral Agent that for so long as the Collateral remains
   subject to the Pledge:

             (a)  neither the Purchase Contract Agent nor such
                  Holders will create or purport to create or allow
                  to subsist any mortgage, charge, lien, pledge or
                  any other security interest over the Collateral or
                  any part of it other than pursuant to this
                  Agreement; and

             (b)  neither the Purchase Contract Agent nor such
                  Holders will sell or otherwise dispose (or attempt
                  to dispose) of the Collateral or any part of it
                  except for the beneficial interest in the
                  Collateral, subject to the Pledge, transferred in
                  connection with the Transfer of the Units.

                                     18








                                 ARTICLE IX

            THE COLLATERAL AGENT AND THE SECURITIES INTERMEDIARY

             SECTION 9.1.   APPOINTMENT, POWERS AND IMMUNITIES.  The
   Collateral Agent shall act as agent for the Company under this
   Agreement with such powers as are specifically vested in the
   Collateral Agent by the terms of this Agreement, together with such
   other powers as are reasonably incidental to such express powers.  The
   Collateral Agent:  (a) shall have no duties or responsibilities except
   those expressly set forth in this Agreement and no implied covenants
   or obligations shall be inferred from this Agreement against the
   Collateral Agent, nor shall the Collateral Agent be bound by the
   provisions of any agreement by any party beyond the specific terms of
   this Agreement; (b) shall not be responsible for any recitals
   contained in this Agreement, or in any certificate or other document
   referred to or provided for in, or received by it under, this
   Agreement, the Units or the Purchase Contract Agreement, or for the
   value, validity, effectiveness, genuineness, enforceability or
   sufficiency of this Agreement (other than as against the Collateral
   Agent), the Units or the Purchase Contract Agreement or any other
   document referred to or provided for in this Agreement or therein or
   for any failure by the Company or any other Person (except the
   Collateral Agent) to perform any of its obligations under this
   Agreement or thereunder or for the perfection, priority or, except as
   expressly required by this Agreement, maintenance of any security
   interest created under this Agreement; (c) shall not be required to
   initiate or conduct any litigation or collection proceedings under
   this Agreement (except pursuant to directions furnished under Section
   9.2, subject to Section 9.6); (d) shall not be responsible for any
   action taken or omitted to be taken by it under this Agreement or
   under any other document or instrument referred to or provided for in
   this Agreement or in connection with this Agreement or therewith,
   except for its own negligence or willful misconduct; and (e) shall not
   be required to advise any party as to selling or retaining, or taking
   or refraining from taking any action with respect to, any securities
   or other property deposited under this Agreement.  Subject to the
   foregoing, during the term of this Agreement, the Collateral Agent
   shall take all reasonable action in connection with the safekeeping
   and preservation of the Collateral.

             No provision of this Agreement shall require the Collateral
   Agent to expend or risk its own funds or otherwise incur any financial
   liability in the performance of any of its duties under this
   Agreement.  In no event shall the Collateral Agent be liable for any
   amount in excess of the Value of the Collateral.  Notwithstanding the
   foregoing, each of the Collateral Agent and the Securities Inter-
   mediary in its individual capacity waives any right of setoff, bankers
   lien, liens or perfection rights as securities intermediary or any
   counterclaim with respect to any of the Collateral.


                                     19






             SECTION 9.2.   INSTRUCTIONS OF THE COMPANY.  The Company
   shall have the right, by one or more instruments in writing executed
   and delivered to the Collateral Agent, to direct the time, method and
   place of conducting any proceeding for the realization of any right or
   remedy available to the Collateral Agent, or of exercising any power
   conferred on the Collateral Agent, or to direct the taking or
   refraining from taking of any action authorized by this Agreement;
   PROVIDED, that (i) such direction shall not conflict with the
   provisions of any law or of this Agreement and (ii) the Collateral
   Agent shall be adequately indemnified as provided in this Agreement.
   Nothing in this Section 9.2 shall impair the right of the Collateral
   Agent in its discretion to take any action or omit to take any action
   which it deems proper and which is not inconsistent with such
   direction.

             SECTION 9.3.   RELIANCE BY COLLATERAL AGENT AND SECURITIES
   INTERMEDIARY.  Each of the Securities Intermediary and the Collateral
   Agent shall be entitled to rely upon any certification, order,
   judgment, opinion, notice or other communication (including, without
   limitation, any of them made by telephone, telecopy, telex, facsimile,
   or email or similar electronic means) believed by it to be genuine and
   correct and to have been signed or sent by or on behalf of the proper
   Person or Persons (without being required to determine the correctness
   of any fact stated therein) and upon advice, opinions and statements
   of legal counsel and other experts selected by the Collateral Agent
   and the Securities Intermediary.  As to any matters not expressly
   provided for by this Agreement, the Collateral Agent and the
   Securities Intermediary shall in all cases be fully protected in
   acting, or in refraining from acting, under this Agreement in
   accordance with instructions given by the Company in accordance with
   this Agreement.

             SECTION 9.4.   RIGHTS IN OTHER CAPACITIES.  The Collateral
   Agent and the Securities Intermediary and their affiliates may
   (without having to account to the Company) accept deposits from, lend
   money to, make their investments in and generally engage in any kind
   of banking, trust or other business with the Purchase Contract Agent,
   any other Person interested in this Agreement and any Holder of Units
   (and any of their respective subsidiaries or affiliates) as if it were
   not acting as the Collateral Agent, and the Collateral Agent, the
   Securities Intermediary and their affiliates may accept fees and other
   consideration from the Purchase Contract Agent and any Holder of Units
   without having to account for the same to the Company; PROVIDED, that
   each of the Securities Intermediary and the Collateral Agent covenants
   and agrees with the Company that it shall not accept, receive or
   permit there to be created in favor of itself and shall take no
   affirmative action to permit there to be created in favor of any other
   Person, any security interest, lien or other encumbrance of any kind
   in or upon the Collateral other than the lien created by the Pledge.

             SECTION 9.5.   NON-RELIANCE ON COLLATERAL AGENT AND
   SECURITIES INTERMEDIARY.  Neither the Securities Intermediary nor the

                                     20






   Collateral Agent shall be required to keep itself informed as to the
   performance or observance by the Purchase Contract Agent or any Holder
   of Units of this Agreement, the Purchase Contract Agreement, the Units
   or any other document referred to or provided for in this Agreement or
   therein or to inspect the properties or books of the Purchase Contract
   Agent or any Holder of Units.  Neither the Collateral Agent nor the
   Securities Intermediary shall  have any duty or responsibility to pro-
   vide the Company with any credit or other information concerning the
   affairs, financial condition or business of the Purchase Contract
   Agent or any Holder of Units (or any of their respective affiliates)
   that may come into the possession of the Collateral Agent or the
   Securities Intermediary or any of their respective affiliates.

             SECTION 9.6.   COMPENSATION AND INDEMNITY.  The Company
   agrees:

             (1)  to pay the Collateral Agent and the Securities
   Intermediary from time to time such compensation as shall be agreed in
   writing between the Company and the Collateral Agent or the Securities
   Intermediary, as the case may be, for all services rendered by them
   hereunder;

             (2)  indemnify and hold harmless the Collateral Agent, the
   Securities Intermediary and each of their respective directors,
   officers, agents and employees (collectively, the "Indemnitees"), from
   and against any and all claims, liabilities, losses, damages, fines,
   penalties and expenses (including reasonable fees and expenses of
   counsel) (collectively, "Losses" and individually, a "Loss") that may
   be imposed on, incurred by, or asserted against, the Indemnitees or
   any of them for following any instructions or other directions upon
   which either the Collateral Agent or the Securities Intermediary is
   entitled to rely pursuant to the terms of this Agreement; and

             (3)  in addition to and not in limitation of paragraph (2)
   immediately above, indemnify and hold the Indemnitees and each of them
   harmless from and against any and all Losses that may be imposed on,
   incurred by or asserted against, the Indemnitees or any of them in
   connection with or arising out of the Collateral Agent's or the
   Securities Intermediary's acceptance or performance of its powers and
   duties under this Agreement, provided the Collateral Agent or the
   Securities Intermediary has not acted with negligence or engaged in
   willful misconduct or bad faith with respect to the specific Loss
   against which indemnification is sought.

             SECTION 9.7.   FAILURE TO ACT.  In the event of any
   ambiguity in the provisions of this Agreement or any dispute between
   or conflicting claims by or among the parties to this Agreement or any
   other Person with respect to any funds or property deposited under
   this Agreement, the Collateral Agent and the Securities Intermediary
   shall be entitled, after prompt notice to the Company and the Purchase
   Contract Agent, at its sole option, to refuse to comply with any and
   all claims, demands or instructions with respect to such property or

                                     21






   funds so long as such dispute or conflict shall continue, and the
   Collateral Agent and the Securities Intermediary shall not be or
   become liable in any way to any of the parties for its failure or
   refusal to comply with such conflicting claims, demands or
   instructions.  The Collateral Agent and the Securities Intermediary
   shall be entitled to refuse to act until either (i) such conflicting
   or adverse claims or demands shall have been finally determined by a
   court of competent jurisdiction or settled by agreement between the
   conflicting parties as evidenced in a writing satisfactory to the
   Collateral Agent or the Securities Intermediary or (ii) the Collateral
   Agent or the Securities Intermediary shall have received security or
   an indemnity satisfactory to it sufficient to save it harmless from
   and against any and all loss, liability or expense which it may incur
   by reason of its acting.  The Collateral Agent and the Securities
   Intermediary may in addition elect to commence an interpleader action
   or seek other judicial relief or orders as the Collateral Agent or the
   Securities Intermediary may deem necessary.  Notwithstanding anything
   contained in this Agreement to the contrary, neither the Collateral
   Agent nor the Securities Intermediary shall be required to take any
   action that is in its opinion contrary to law or to the terms of this
   Agreement, or which would in its opinion subject it or any of its
   officers, employees or directors to liability.

             SECTION 9.8.   RESIGNATION OF COLLATERAL AGENT AND
   SECURITIES INTERMEDIARY.

             (a)  Subject to the appointment and acceptance of a
   successor Collateral Agent as provided below, (i) the Collateral Agent
   may resign at any time by giving notice to the Company and the
   Purchase Contract Agent as attorney-in-fact for the Holders of Units,
   (ii) the Collateral Agent may be removed at any time by the Company,
   and (iii) if the Collateral Agent fails to perform any of its material
   obligations under this Agreement in any material respect for a period
   of not less than 20 days after receiving written notice of such
   failure by the Purchase Contract Agent and such failure shall be
   continuing, the Purchase Contract Agent may, but shall not be
   obligated to, remove the Collateral Agent.  The Purchase Contract
   Agent shall promptly notify the Company of any removal of the
   Collateral Agent pursuant to clause (iii) of the immediately preceding
   sentence.  Upon any such resignation or removal, the Company shall
   have the right to appoint a successor Collateral Agent.  If no
   successor Collateral Agent shall have been so appointed and shall have
   accepted such appointment within 30 days after the retiring Collateral
   Agent's giving of notice of resignation or such removal, then the
   retiring Collateral Agent may petition any court of competent
   jurisdiction for the appointment of a successor Collateral Agent.  The
   Collateral Agent shall be a bank which has an office (or an agency
   office) in New York, New York with a combined capital and surplus of
   at least $50,000,000 and shall not be the Purchase Contract Agent or
   any of its affiliates.  Upon the acceptance of any appointment as
   Collateral Agent by a successor Collateral Agent, such successor
   Collateral Agent shall immediately succeed to and become vested with

                                     22






   all the rights, powers, privileges and duties of the retiring
   Collateral Agent, and the retiring Collateral Agent shall take all
   appropriate action to transfer any money and property held by it under
   this Agreement (including the Collateral) to such successor Collateral
   Agent.  The retiring Collateral Agent shall, upon such succession, be
   discharged from its duties and obligations as Collateral Agent.  After
   any retiring Collateral Agent's resignation as Collateral Agent, the
   provisions of this Article IX shall continue in effect for its benefit
   in respect of any actions taken or omitted to be taken by it while it
   was acting as the Collateral Agent.

             (b)  Subject to the appointment and acceptance of a
   successor Securities Intermediary as provided below, (i) the
   Securities Intermediary may resign at any time by giving notice to the
   Company and the Purchase Contract Agent as attorney-in-fact for the
   Holders of Units, (ii) the Securities Intermediary may be removed at
   any time by the Company, and (iii) if the Securities Intermediary
   fails to perform any of its material obligations under this Agreement
   in any material respect for a period of not less than 20 days after
   receiving written notice of such failure by the Purchase Contract
   Agent and such failure shall be continuing, the Securities
   Intermediary may be removed by the Purchase Contract Agent.  The
   Purchase Contract Agent shall promptly notify the Company of any
   removal of the Securities Intermediary pursuant to clause (iii) of the
   immediately preceding sentence.  Upon any such resignation or removal,
   the Company shall have the right to appoint a successor Securities
   Intermediary.  If no successor Securities Intermediary shall have been
   so appointed and shall have accepted such appointment within 30 days
   after the retiring Securities Intermediary's giving of notice of
   resignation or such removal, then the retiring Securities Intermediary
   may petition any court of competent jurisdiction for the appointment
   of a successor Securities Intermediary.  The Securities Intermediary
   shall be a bank which has an office (or an agency office) in New York,
   New York with a combined capital and surplus of at least $50,000,000
   and shall not be the Purchase Contract Agent or any of its affiliates.
   Upon the acceptance of any appointment as Securities Intermediary by a
   successor Securities Intermediary, such successor Securities
   Intermediary shall immediately succeed to and become vested with all
   the rights, powers, privileges and duties of the retiring Securities
   Intermediary, and the retiring Securities Intermediary shall take all
   appropriate action to transfer any money and property held by it under
   this Agreement (including the Collateral) to such successor Securities
   Intermediary.  The retiring Securities Intermediary shall, upon such
   succession, be discharged from its duties and obligations as
   Securities Intermediary.  After any retiring Securities Intermediary's
   resignation as Securities Intermediary, the provisions of this
   Article 9 shall continue in effect for its benefit in respect of any
   actions taken or omitted to be taken by it while it was acting as the
   Securities Intermediary.

             SECTION 9.9.   RIGHT TO APPOINT AGENT OR ADVISOR.  The
   Collateral Agent shall have the right to appoint agents or advisors in

                                     23






   connection with any of its duties under this Agreement, and the
   Collateral Agent shall not be liable for any action taken or omitted
   by, or in reliance upon the advice of, such agents or advisors
   selected in good faith.  The appointment of agents and advisors
   pursuant to this Section 9.9 shall be subject to prior consent of the
   Company, which consent shall not be unreasonably withheld.

             SECTION 9.10.  SURVIVAL.  The provisions of this Article IX
   shall survive termination of this Agreement and the resignation or
   removal of the Collateral Agent or the Securities Intermediary.

             SECTION 9.11.  EXCULPATION.  Anything in this Agreement to
   the contrary notwithstanding, in no event shall the Collateral Agent
   or the Securities Intermediary or their officers, directors, employees
   or agents be liable under this Agreement to any third party for
   indirect, special, punitive, or consequential loss or damage of any
   kind, including lost profits, whether or not the likelihood of such

        Company, and the assumption by any such successor of the
        covenants and agreements of the Company;

             (2)  to add to the covenants of the Company for the benefit
        of the Holders, or to surrender any right or power conferred upon
        the Company in this Agreement, so long as such covenants or such
        surrender does not adversely affect the validity, perfection or
        priority of the Pledge;

             (3)  to evidence and provide for the acceptance of
        appointment by a successor Collateral Agent, Securities
        Intermediary or Purchase Contract Agent; or

             SECTION 10.2.  AMENDMENT WITH CONSENT OF HOLDERS.  With the
   consent of the Holders of not less than a majority of the Purchase
   Contracts at the time outstanding, by Act of said Holders delivered to
   the Company, the Purchase Contract Agent, the Securities Intermediary
   or the Collateral Agent, as the case may be, the Company, when duly
   authorized, the Purchase Contract Agent, the Securities Intermediary
   and the Collateral Agent may amend this Agreement for the purpose of
   modifying in any manner the provisions of this Agreement or the rights
   of the Holders in respect of the Units; PROVIDED, that no such
   supplemental agreement shall, without the unanimous consent of the
   Holders of each Outstanding Unit adversely affected by it,

             (1)  change the amount or type of Collateral underlying a
        Unit (except for the rights of holders of Corporate Units to
        substitute the Treasury Securities for the Pledged Debentures, or
        the rights of Holders of Treasury Units to substitute Debentures
        for the Pledged Treasury Securities), impair the right of the
        Holder of any Unit to receive distributions on the underlying
        Collateral or otherwise adversely affect the Holder's rights in
        or to such Collateral;

             (2)  otherwise effect any action that would require the
        consent of the Holder of each Outstanding Unit affected by such
        action pursuant to the Purchase Contract Agreement if such action
        were effected by an agreement supplemental to it; or

             (3)  reduce the percentage of Purchase Contracts the consent
        of the Holders of which is required for any such amendment;

   PROVIDED, that if any amendment or proposal referred to above would
   adversely affect only the Corporate Units or only the Treasury Units,
   then only the affected class of Holder as of the record date for the
   Holders entitled to vote will be entitled to vote on such amendment or
   proposal, and such amendment or proposal shall not be effective except
   with the consent of Holders of not less than a majority of such class;
   and PROVIDED FURTHER, that the unanimous consent of the Holders of
   each outstanding Purchase Contract of such class affected thereby
   shall be required to approve any amendment or proposal specified in
   clauses (1) - (3) above.

             It shall not be necessary for any Act of Holders under this

   it shall be sufficient if such Act shall approve the substance of the
   amendment.

   amendment permitted by this Article, the Collateral Agent, the
   Securities Intermediary and the Purchase Contract Agent shall be
