                  preparing,   executing   and   filing   the   certificate   of
                  cancellation  with the  Secretary  of  State  of the  State of

                                                        14






                           (I)  after an  Event of  Default  (other  than  under
                  paragraph  (b), (c), (d) or (e) of the definition of such term
                  if such Event of Default is by or with respect to the Property
                  Trustee)  taking of any action  incidental to the foregoing as
                  the  Property  Trustee  may  from  time to time  determine  is
                  necessary  or  advisable  to give  effect to the terms of this
                  Trust Agreement and to protect and conserve the Trust Property
                  for the benefit of the Holders  (without  consideration of the
                  effect of any such action on any particular Holder);

         (b) So long as this Trust Agreement remains in effect, the Issuer Trust
(or the  Issuer  Trustees  acting  on  behalf  of the  Issuer  Trust)  shall not
undertake any business,  activities or transaction  except as expressly provided
herein or contemplated  hereby.  In particular,  the Issuer Trustees,  acting in
their capacity as such,  shall not (i) acquire any  investments or engage in any
activities not authorized by this Trust Agreement,  (ii) sell, assign, transfer,
exchange,  mortgage,  pledge,  set-off or otherwise  dispose of any of the Trust
Property  or  interests  therein,  including  to  Holders,  except as  expressly

any  indebtedness  for  borrowed  money or issue any other debt,  or (v) take or
consent to any action that would result in the placement of a Lien on any of the

adverse to the interest of the Issuer Trust or the Holders in their  capacity as
Holders.

         (c) In  connection  with the issue and sale of the Capital  Securities,
the Depositor shall have the right and responsibility to assist the Issuer Trust
with respect to, or effect on behalf of the Issuer Trust, the following (and any
actions taken by the Depositor in furtherance of the following prior to the date
of this Trust Agreement are hereby ratified and confirmed in all respects):

                  (i) the taking of any action  necessary  or  desirable to sell
         the Capital  Securities  in a transaction  or a series of  transactions
         exempt from the registration requirements of the Securities Act;

                  (ii) the determination of the States, or other  jurisdictions,
         if any, in which to take appropriate  action to qualify or register for
         sale all or part of the Capital Securities and the determination of any
         and all such  acts,  other  than  actions  that  must be taken by or on
         behalf of the Issuer  Trust,  and the advice to the Issuer  Trustees of
         actions  they  must  take  on  behalf  of the  Issuer  Trust,  and  the
         preparation  for  execution  and filing of any documents to be executed
         and filed by the Issuer Trust or on behalf of the Issuer Trust,  as the
         Depositor  deems  necessary  or  advisable  in order to comply with the
         applicable  laws of any such States in connection  with the sale of the
         Capital Securities;

                  (iii) the  negotiation  of the terms of, and the execution and
         delivery of, the Purchase Agreement; and



                                                        15





                  (iv) the taking of any other actions necessary or desirable to
         carry out any of the foregoing activities.

         (d) Notwithstanding anything herein to the contrary, the Administrative
Trustees are  authorized and directed to conduct the affairs of the Issuer Trust
and to operate the Issuer  Trust so that the Issuer  Trust will not be deemed to
be an  "investment  company"  required  to be  registered  under the  Investment
Company Act, and will not be taxable as a  corporation  or  classified  as other
than a grantor trust for United States  Federal  income tax purposes and so that
the  Debentures  will be treated as  indebtedness  of the  Depositor  for United
States  Federal income tax purposes.  In this  connection,  each  Administrative
Trustee  and the  Holder of the Common  Securities  are  authorized  to take any
action,  not inconsistent  with applicable law, the Certificate of Trust or this
Trust  Agreement,  that such  Administrative  Trustee  or  Holder of the  Common
Securities  determines  in its  discretion to be necessary or desirable for such
purposes,  as long as such  action  does not  adversely  affect in any  material
respect the interests of the Holders of the Outstanding Capital  Securities.  In
no event shall the Issuer  Trustees be liable to the Issuer Trust or the Holders
for any failure to comply with this section that results from a change in law or
regulation or in the interpretation thereof.

         SECTION 2.8. Assets of Trust.

         The assets of the Issuer Trust shall consist of the Trust Property.

         SECTION 2.9. Title to Trust Property.

         Legal title to all Trust  Property  shall be vested at all times in the
Property Trustee (in its capacity as such) and shall be held and administered by
the  Property  Trustee  in trust for the  benefit  of the  Issuer  Trust and the
Holders in accordance with this Trust Agreement.


                                   ARTICLE III

                                 PAYMENT ACCOUNT

         SECTION 3.1. Payment Account.

         (a) On or  prior  to the  Closing  Date,  the  Property  Trustee  shall
establish the Payment  Account.  The Property  Trustee and its agents shall have
exclusive  control  and sole right of  withdrawal  with  respect to the  Payment
Account for the purpose of making deposits in and  withdrawals  from the Payment
Account in accordance with this Trust  Agreement.  All monies and other property
deposited or held from time to time in the Payment  Account shall be held by the
Property Trustee in the Payment Account for the exclusive benefit of the Holders
and for distribution as herein provided, including (and subject to) any priority
of payments provided for herein.



                                                        16





         (b) The Property Trustee shall deposit in the Payment Account, promptly
upon  receipt,  all  payments  of  principal  of or  interest  on, and any other
payments  or  proceeds  with  respect to, the  Debentures.  Amounts  held in the
Payment  Account  shall  not  be  invested  by  the  Property   Trustee  pending
distribution thereof.


                                   ARTICLE IV

                      DISTRIBUTIONS; REDEMPTION; CONVERSION

         SECTION 4.1. Distributions.

         (a) The Trust Securities  represent undivided  beneficial  interests in
the Trust Property,  and distributions  ("Distributions"),  comprised of (i) the
Distribution  Amount,  (ii) any Additional  Sums and (iii) and other payments in
respect of the  Debentures,  will be made on the Trust  Securities  on the dates
that payments of interest are made on the Debentures. Accordingly:

                  (i) Distributions on the Trust Securities shall be cumulative,
         and shall accumulate whether or not there are funds of the Issuer Trust
         available  for  the  payment  of  Distributions.   Distributions  shall
         accumulate from December 31, 1997, and, except in the event (and to the
         extent) that the Depositor  exercises its right to defer the payment of
         interest on the Debentures pursuant to the Indenture,  shall be payable
         semi-annually  in  arrears  on  January  15 and  July 15 of each  year,
         commencing  January 15, 1998.  If any date on which a  Distribution  is
         otherwise  payable on the Trust  Securities is not a Business Day, then
         the payment of such  Distribution  shall 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 next  succeeding
         Business Day falls within 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 the date on which such  payment was
         originally  payable  (each date on which  distributions  are payable in
         accordance with this Section 4.1(a)(i), a "Distribution Date").

                  (ii) The Trust  Securities  shall be entitled to Distributions
         (before  giving  effect  to  any   Additional   Sums)  payable  at  the
         Distribution  Rate  multiplied by the  Liquidation  Amount of the Trust
         Securities.  The amount of Distributions payable for any period will be
         computed  on the basis of the actual  number of days in the  applicable
         Distribution  period  (which  actual  number of days shall  include the
         first day but exclude the last day of such Distribution period) divided
         by 360. The period  beginning on, and  including,  the date of original
         issuance,  and ending on, but excluding,  the first  Distribution Date,
         and each successive period beginning on, and including,  a Distribution
         Date, and ending on, but excluding,  the next  succeeding  Distribution
         Date  is  herein  called  a  "Distribution   period").  The  amount  of
         Distributions  payable for any period shall also include any Additional
         Sums, if any, so payable in respect of such period.



                                                        17





                  (iii)  Distributions  on the Trust Securities shall be made by
         the Property  Trustee from the Payment  Account and shall be payable on
         each  Distribution  Date only to the extent  that the Issuer  Trust has
         funds then on hand and available in the Payment Account for the payment
         of such Distributions.

         (b)   Distributions   on  the  Trust   Securities  with  respect  to  a
Distribution  Date shall be payable to the Holders thereof as they appear on the
Securities  Register  for the Trust  Securities  at the close of business on the
January 1 or July 1 (whether or not a Business Day) next  preceding the relevant
Distribution Date.

         (c) (i) The  Issuer  Trust  shall  cause  the  Distribution  Rate,  the
Distribution  Amount in respect of each Trust Security and the Distribution Date
for each Distribution period to be notified to the Property Trustee, each Paying
Agent  appointed  by the Issuer Trust and any  securities  exchange or automated
quotation  system on which the Trust Securities are listed or quoted and also to
be  notified  to the  Holders of the Trust  Securities  in  accordance  with the
provisions  of  Section  10.8,  in each  case as soon as  practicable  after the
determination  thereof but in no event later than the second  Business Day after
the Determination Date in respect of such Distribution period.

                  (ii)  All  calculations  of  the  Distribution  Rate  and  the
Distribution Amount by or on behalf of the Issuer Trust shall (in the absence of
manifest  error) be final and  binding  on all  parties,  and all  certificates,
communications, opinions, determinations, calculations, quotations and decisions
given,  expressed,  made or obtained for the purposes of the  provisions of this
Section 4.1(c) or the provisions of the Indenture relating to the calculation of
the  Interest  Rate (as  defined  in the  Indenture),  shall (in the  absence of
willful  default,  bad faith or manifest  error) be binding on the Issuer Trust,
the  Depositor,  the  Debenture  Trustee  and all of the  Holders  of the  Trust
Securities, and no liability shall (in the absence of willful default, bad faith
or  manifest  error)  attach to the  Debenture  Trustee in  connection  with the
exercise or non-exercise by it of its powers, duties and discretions.

         SECTION 4.2. Redemption.

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

                  (ii) If at any time  following a  Conversion  Date,  less than
five percent (5%) in principal amount of the Debentures originally issued by the
Depositor remain outstanding,  such Debentures are redeemable,  at the option of
the  Depositor,  in whole but not in part,  at a  Redemption  Price equal to the
aggregate principal amount thereof, and all accrued and unpaid interest; in such
event,  the  proceeds  from such  redemption  shall be  applied  to  redeem  the
Outstanding Trust Securities.



                                                        18





                  (iii) In addition, the Issuer Trust will be required to redeem
at the Redemption  Price stated in Section 11.7 of the Indenture,  the amount of
Trust Securities that the Purchaser proposes to dispose or transfer,  if subject
to Section  5.4(b)(2)(E),  the Depositor vetoes the Purchaser's choice of Person
to whom the Purchaser desires to dispose or transfer such Securities.

                  (iv) Pursuant to Section 11.8 of the Indenture,  the Depositor
may be required to redeem all Outstanding Trust Securities at a Redemption Price
stated in Section 11.8 of the Indenture.

         (b) Notice of redemption shall be given by the Property Trustee and the
Conversion Agent 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 or if the Redemption Price cannot be
         calculated  prior to the time the notice is  required  to be sent,  the
         estimate of the Redemption  Price provided  pursuant to (and as defined
         in) the Indenture  together with a statement that it is an estimate and
         that the  actual  Redemption  Price  will be  calculated  on the  third
         Business  Day prior to the  Redemption  Date (and,  if an  estimate  is
         provided,  that a further notice shall be sent of the actual Redemption
         Price on the date on which such Redemption Price is calculated);

                  (iii)  the  CUSIP  number  or  CUSIP  numbers  of the  Capital
Securities affected;

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

                  (v) If the  Capital  Securities  are  convertible,  (A) that a
         Holder of  Capital  Securities  who  desires to  convert  such  Capital
         Securities  called for  redemption  must satisfy the  requirements  for
         conversion contained in Section 4.3 below and (B) the Conversion Price;

                  (vi) 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 accumulate on and after such
         date, except as provided in Section 4.2(d) below; and

                  (vii) the place or places where the Trust Securities are to be
         surrendered for the payment of the Redemption Price.



                                                        19





         The Issuer  Trust in issuing  the Trust  Securities  may use "CUSIP" or
"private placement" numbers (if then generally in use), and, if so, the Property
Trustee shall indicate the "CUSIP" or "private  placement"  numbers of the Trust
Securities in notices of redemption  and related  materials as a convenience  to
Holders;  provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Trust  Securities
or as contained in any notice of redemption and related materials.

         (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  Issuer  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  Capital  Securities,  then,  by 12:00  noon,  New York  City  time,  on the
Redemption  Date,  subject to Section  4.2(c),  the Property  Trustee will, with
respect to the Capital Securities,  irrevocably deposit with the Paying Agent or
Paying Agents,  to the extent  available  therefor,  funds sufficient to pay the
applicable  Redemption  Price and will give the  Paying  Agent or Paying  Agents
irrevocable  instructions  and  authority  to pay the  Redemption  Price  to the
Holders of the Capital  Securities  upon  surrender of their Capital  Securities
Certificates.  Notwithstanding the foregoing,  Distributions payable on or prior
to the Redemption Date for any Trust  Securities  called for redemption shall be
payable to the Holders of such Trust Securities as they appear on the Securities
Register 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 Holders holding Trust Securities so
called for  redemption  will cease,  except the right of such Holders to receive
the  Redemption  Price and any  Distribution  payable  in  respect  of the Trust
Securities 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 (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 Issuer
Trust or by the Depositor pursuant to the Guarantee Agreement,  Distributions on
such Trust Securities will continue to accumulate,  as set forth in Section 4.1,
from the  Redemption  Date  originally  established by the Issuer 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) Subject to Section 4.3(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 pro
rata to the Common Securities and the Capital Securities based upon the relative
Liquidation Amounts of such classes. The particular Capital Securities


                                                        20





to be redeemed shall be selected on a pro rata basis based upon their respective
Liquidation  Amounts not more than 60 days prior to the  Redemption  Date by the
Property Trustee from the Outstanding  Capital  Securities not previously called
for redemption, provided that, after giving effect to such redemption, no Holder
shall hold Capital Securities with an aggregate  Liquidation Amount of less than
$1,000.  The Property Trustee shall promptly notify the Securities  Registrar in
writing of the Capital  Securities  selected for redemption  and, in the case of
any Capital 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 Capital
Securities shall relate, in the case of any Capital Securities redeemed or to be
redeemed  only in part, to the portion of the  aggregate  Liquidation  Amount of
Capital Securities that has been or is to be redeemed.

         SECTION 4.3.  Conversion.  The Holders of Trust Securities,  subject to
the  limitations  set forth in this  Section,  shall  have the  right,  at their
option, to cause the Conversion Agent to convert Trust Securities,  on behalf of
the  converting  Holders,  into shares of Common  Stock in the manner  described
herein on and subject to the following terms and conditions:

                  (i) Subject to the receipt by the  Purchaser and the Depositor
         of the  appropriate  Regulatory  Approvals  (as defined  below) and the
         termination   of   the   applicable    waiting    periods   under   the
         Hart-Scott-Rodino  Antitrust  Improvements Act of 1976, as amended, and
         the  related  regulations  and  published  interpretations,  the  Trust
         Securities will be convertible into fully paid and nonassessable shares
         of Common Stock  pursuant to the Holder's  direction to the  Conversion
         Agent  to  exchange  such  Trust   Securities  for  a  portion  of  the
         Debentures,  and  immediately  convert such amount of  Debentures  into
         fully paid and nonassessable  shares of Common Stock at an initial rate
         of 11.7647  shares of Common  Stock for each Trust  Security  (which is
         equivalent  to a  conversion  price of $85 per share of Common  Stock),
         subject  to  certain  adjustments  set  forth in the  Indenture  (as so
         adjusted,  "Conversion Price").  "Regulatory  Approvals" shall mean all
         necessary  insurance  regulatory and other filings and/or approvals and
         any licenses and permits, authorizations, consents, orders or approvals
         of, or  registrations,  declarations  or  filings  with all  regulatory
         bodies as may be required to be obtained or made with respect to either
         party in order to permit the  parties to  consummate  the  transactions
         contemplated  hereby  which  are to be  consummated  on or prior to the
         Closing Date.

                  (ii) In order to convert Trust  Securities  into Common Stock,
         the  Holder of such Trust  Securities  shall  submit to the  Conversion
         Agent an irrevocable  Notice of Conversion,  as set forth in Exhibit F,
         to convert Trust  Securities on behalf of such Holder,  together,  with
         the  certificates  representing  the Trust  Securities.  The  Notice of
         Conversion  shall (i) set forth the  number of Trust  Securities  to be
         converted and the name or names, if other than the Holder, in which the
         shares of Common Stock should be issued and (ii) direct the  Conversion
         Agent (a) to  exchange  such  Trust  Securities  for a  portion  of the
         Debentures  held  by the  Property  Trustee  (at the  rate of  exchange
         specified in the preceding  paragraph) and (b) to  immediately  convert
         such  Debentures,  on behalf of such Holder,  into Common Stock (at the
         conversion rate specified in the preceding


                                                        21





         paragraph).  The Conversion  Agent shall notify the Property Trustee of
         the Holder's election to exchange Trust Securities for a portion of the
         Debentures held by the Property Trustee and the Property Trustee shall,
         upon  receipt  of such  notice,  deliver  to the  Conversion  Agent the
         appropriate  principal  amount of Debentures for exchange in accordance
         with this Section.  The  Conversion  Agent shall  thereupon  notify the
         Depositor of the  Holder's  election to convert  such  Debentures  into
         shares of Common  Stock.  Holders of Trust  Securities  at the close of
         business  on a  Distribution  payment  record  date will be entitled to
         receive  the  Distribution   paid  on  such  Trust  Securities  on  the
         corresponding  Distribution Date notwithstanding the conversion of such
         Trust  Securities   following  such  record  date  but  prior  to  such
         Distribution Date. Except as provided above,  neither the Trust nor the
         Depositor will make, or be required to make, any payment,  allowance or
         adjustment upon any conversion on account of any accumulated and unpaid
         Distributions whether or not in arrears accrued on the Trust Securities
         surrendered for conversion, or on account of any accumulated and unpaid
         dividends on the shares of Common  Stock  issued upon such  conversion.
         Trust  Securities  shall be deemed to have been  converted  immediately
         prior to the  close  of  business  on the day on  which an  irrevocable
         Notice of Conversion  relating to such Trust  Securities is received by
         the Conversion  Agent in accordance  with the foregoing  provision (the
         "Conversion  Date").  The Person or  Persons  entitled  to receive  the
         Common  Stock  issuable  upon  conversion  of the  Debentures  shall be
         treated for all purposes as the record holder or holders of such Common
         Stock on the date of conversion. As promptly as practicable on or after
         the  Conversion  Date,  the  Depositor  shall  issue and deliver at the
         office of the Conversion  Agent a certificate or  certificates  for the
         number of full shares of Common Stock  issuable  upon such  conversion,
         together with the cash payment,  if any, in lieu of any fraction of any
         share to the Person or Persons  entitled  to receive  the same,  unless
         otherwise  directed by the Holder in the notice of  conversion  and the
         Conversion  Agent shall  distribute such certificate or certificates to
         such Person or Persons.

                  (iii)  Each  Holder  of a  Trust  Security  by its  acceptance
         thereof initially appoints the Property Trustee,  not in its individual
         capacity but solely as conversion  agent (the  "Conversion  Agent") for
         the  purpose  of  effecting  the  conversion  of  Trust  Securities  in
         accordance   with  this  Section.   In  effecting  the  conversion  and
         transactions  described in this Section,  the Conversion Agent shall be
         acting as agent of the  Holders  of Trust  Securities  directing  it to
         effect such  conversion  transactions.  The Conversion  Agent is hereby
         authorized  (i) to  exchange  Trust  Securities  from  time to time for
         Debentures  held by the Trust in connection with the conversion of such
         Trust  Securities in  accordance  with this Section and (ii) to convert
         all or a portion of the  Debentures  into Common Stock and thereupon to
         deliver such shares of Common Stock in accordance  with the  provisions
         of  this  Section  and to  deliver  to the  Property  Trustee  any  new
         Debenture or Debentures for any resulting  unconverted principal amount
         delivered to the Conversion Agent by the Debenture Trustee.

                  (iv) No fractional  shares of Common Stock will be issued as a
         result of conversion,  but, in lieu thereof,  such fractional  interest
         will be paid in cash by the


                                                        22





         Depositor  to the  Conversion  Agent in an amount  equal to the Current
         Market  Price of the  fractional  share of the  Common  Stock,  and the
         Conversion  Agent  will in turn  make  such  payment  to the  Holder or
         Holders of Trust Securities so converted.

                  (v) Nothing in this Section 4.3 shall limit the requirement of
         the  Trust  to  withhold  taxes  pursuant  to the  terms  of the  Trust
         Securities or as set forth in this  Agreement or otherwise  required of
         the Property Trustee or the Trust to pay any amounts on account of such
         withholdings.

         SECTION 4.4. Subordination of Common Securities.

         (a)  Payment  of  Distributions  on, the  Redemption  Price of, and the
Liquidation  Distribution  in respect of the Trust  Securities,  as  applicable,
shall be made,  subject to Section 4.2(e),  pro rata among the Common Securities
and  the  Capital  Securities  based  on the  Liquidation  Amount  of the  Trust
Securities; provided, however, that if on any Distribution Date, Redemption Date
or Liquidation  Date any Event of Default  resulting  from a Debenture  Event of
Default  specified  in  Section  5.1(1) or 5.1(2) of the  Indenture  shall  have
occurred and be continuing,  no payment of any Distribution on, Redemption Price
of, or Liquidation  Distribution in respect 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 on all Outstanding Capital 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
Capital Securities then called for redemption,  or in the case of payment of the
Liquidation Distribution the full amount of such Liquidation Distribution on all
Outstanding  Capital  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 on, the Redemption Price of or
the Liquidation  Distribution in respect of the Capital  Securities then due and
payable.

         (b) In the case of the  occurrence  of any Event of  Default  resulting
from any Debenture Event of Default,  the Holder of the Common  Securities shall
have no right to act with respect to any such Event of Default  under this Trust
Agreement  until the effects of all such Events of Default  with  respect to the
Capital Securities have been cured,  waived or otherwise  eliminated.  Until all
such Events of Default  under this Trust  Agreement  with respect to the Capital
Securities  have been so cured,  waived or  otherwise  eliminated,  the Property
Trustee shall act solely on behalf of the Holders of the Capital  Securities and
not on behalf of the Holder of the Common  Securities,  and only the  Holders of
the Capital Securities will have the right to direct the Property Trustee to act
on their behalf.

         SECTION 4.5. Payment Procedures.

         Payments  of  Distributions  or of the  Redemption  Price,  Liquidation
Amount or any other amounts in respect of the Capital  Securities  shall be made
by check  mailed to the address of the Person  entitled  thereto as such address
shall appear on the Securities Register. Payments in


                                                        23





respect  of the  Common  Securities  shall  be made in such  manner  as shall be
mutually  agreed  between the Property  Trustee and the Holder of all the Common
Securities.

         SECTION 4.6. 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
Issuer Trust. In this regard, the Administrative  Trustees shall (a) prepare and
file (or cause to be prepared  and filed) all  Internal  Revenue  Service  forms
required to be filed in respect of the Issuer  Trust in each taxable year of the
Issuer  Trust,  and (b)  prepare  and  furnish  (or  cause  to be  prepared  and
furnished)  to each Holder all Internal  Revenue  Service  forms  required to be
provided by the Issuer  Trust.  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 Issuer Trustees shall comply with
United  States  Federal   withholding  and  backup   withholding  tax  laws  and
information reporting requirements with respect to any payments to Holders under
the Trust Securities.

         SECTION 4.7. Payment of Taxes, Duties, Etc. of the Issuer Trust.

         Upon receipt  under the  Indenture  of  Additional  Sums,  the Property
Trustee  shall  promptly  pay any  taxes,  duties  or  governmental  charges  of
whatsoever nature (other than withholding  taxes) imposed on the Issuer Trust by
the  United  States or any other  taxing  authority  with  respect to which such
Additional Sums were paid.

         SECTION 4.8. Payments under Indenture or Pursuant to Direct Actions.

         Any amount payable hereunder to any Holder of Capital  Securities shall
be reduced by the amount of any  corresponding  payment such Holder has directly
received  pursuant to Section 5.9 of the Indenture or Section 5.12 of this Trust
Agreement.

                          TRUST SECURITIES CERTIFICATES

         SECTION 5.1. Initial Ownership.

         Upon the  creation  of the  Issuer  Trust and the  contribution  by the
Depositor  pursuant  to  Section  2.3  and  until  the  issuance  of  the  Trust
Securities,  and at any time during which no Trust  Securities are  Outstanding,
the Depositor shall be the sole beneficial owner of the Issuer Trust.

         SECTION 5.2. The Trust Securities Certificates.

          Unless  otherwise  set  forth  herein,  a  single  Capital  Securities
Certificate representing the Capital Securities shall be issued to the Purchaser
in the form of a definitive  Capital  Securities  Certificate.  A single  Common
Security  Certificate  representing the Common Securities shall be issued to the
Depositor  in the  form  of a  definitive  Common  Securities  Certificate.  The
consideration  received by the Trust for the  issuance  of the Trust  Securities
shall  constitute  a  contribution  to the  capital  of the  Trust and shall not
constitute a loan to the Trust.

         The Purchaser shall receive a Capital  Securities  Certificate  bearing
the  Restricted  Securities  Legend  ("Restricted   Certificated   Securities").
Restricted  Certificated  Securities  shall  include the  Restricted  Securities
Legend unless removed in accordance with Section 5.4(c) hereof.

         The Trust  Securities  Certificates  shall be executed on behalf of the
Trust by manual or facsimile  signature of at least one  Administrative  Trustee
and authenticated by the Property Trustee. Trust Securities Certificates bearing
the manual or facsimile  signatures  of  individuals  who were, at the time when
such  signatures  shall have been  affixed,  authorized to sign on behalf of the
Issuer Trust,  shall be validly issued and entitled to the benefit 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 Section 5.4.

         SECTION 5.3. Execution and Delivery of Trust Securities Certificates.

         On the Closing  Date,  the  Administrative  Trustees  shall cause Trust
Securities  Certificates,  in an  aggregate  Liquidation  Amount as  provided in
Sections 2.4 and 2.5, to be executed on behalf of the Issuer Trust and delivered
to or upon the written order of the Depositor, executed by an authorized officer
thereof,  without  further  corporate  action by the  Depositor,  in  authorized
denominations.

     SECTION  5.4.  Registration,   Transfer  and  Exchange  Generally;  Certain
Transfers and Exchanges; Securities Act Legends.

         (a) Registration,  Transfer and Exchange Generally.  The Administrative
Trustees  shall  keep or cause to be kept,  at the  office or agency  maintained
pursuant to Section 5.8, a register or registers (the "Securities  Register") in
which the registrar and transfer agent with respect to the Trust Securities (the
"Securities  Registrar"),  subject  to  such  reasonable  regulations  as it may
prescribe,  shall  provide  for  the  registration  of  the  Capital  Securities
Certificate and (subject to Section 5.10) the Common Securities  Certificate and
of transfers  and  exchanges  of the Capital  Securities  Certificate  as herein
provided. The Property Trustee is hereby appointed Securities


                                                        25





Registrar for the purpose of registering the Capital Securities  Certificate and
(subject to Section 5.10) the Common  Securities  Certificate  and transfers and
exchanges thereof as provided herein.

         Upon surrender for  registration of transfer of the Capital  Securities
Certificate  at the office or agency  maintained  pursuant to Section  5.8,  the
Administrative  Trustees  or any one of them shall  execute  and  deliver to the
Property  Trustee,  and the Property  Trustee shall deliver,  in the name of the
designated  transferee  or  transferees,  one or  more  new  Capital  Securities
Certificates in authorized  denominations of a like aggregate Liquidation Amount
and bearing such restrictive legends as may be required by this Trust Agreement,
dated the date of execution by such Administrative Trustee or Trustees.

         At the option of the Holder, the Capital Securities  Certificate may be
exchanged for other Capital  Securities  Certificates  of the same series of any
authorized  denominations,  of like  tenor  and  aggregate  Liquidation  Amount,
bearing such restrictive  legends as may be required by this Trust Agreement and
bearing  a number  not  contemporaneously  Outstanding,  upon  surrender  of the
Capital  Securities  Certificate  to be  exchanged  at such  office  or  agency.
Whenever any Capital Securities  Certificate is so surrendered for exchange, the
Administrative  Trustees  or any one of them shall  execute  and  deliver to the
Property Trustee, and the Property Trustee shall deliver, the Capital Securities
Certificates that the Holder making the exchange is entitled to receive.

         All Capital  Securities issued upon any transfer or exchange of Capital
Securities  shall  evidence the same interest in the assets of the Issuer Trust,
and be entitled to the same benefits under this Trust Agreement,  as the Capital
Securities surrendered upon such transfer or exchange.

         The Securities Registrar shall not be required,  (i) to issue, register
the transfer of or exchange any Capital  Security  during a period  beginning at
the opening of business 15 days before the day of selection  for  redemption  of
such  Capital  Securities  pursuant  to  Article  IV and  ending at the close of
business on the day of mailing of the notice of redemption,  or (ii) to register
the transfer of or exchange any Capital  Security so selected for  redemption in
whole  or in  part,  except,  in the case of any  such  Capital  Security  to be
redeemed in part, any portion thereof not to be redeemed.

         The  Capital  Securities   Certificate  presented  or  surrendered  for
registration  of transfer or exchange shall be duly endorsed,  or be accompanied
by a written  instrument of transfer in form  satisfactory to an  Administrative
Trustee  and the  Securities  Registrar  duly  executed  by the  Holder  or such
Holder's attorney duly authorized in writing. The Capital Securities Certificate
surrendered  for  registration  of transfer or  exchange  shall be canceled  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 the Capital Securities Certificate, but the Issuer Trust may require
payment of a sum sufficient to


                                                        26





cover any tax or governmental  charge that may be imposed in connection with any
transfer or exchange of the Capital Securities Certificate.

         (b)   Registration,   Transfer,   and  Exchange.   A  Security  may  be
transferred,  in whole or in part, to a Person who takes delivery in the form of
another Security,  provided that the following  provisions are met. When Capital
Securities  are presented to the  Securities  Registrar  with a request:  (1) to
register the transfer of such Securities; or (2) to exchange such Securities for
Capital Securities in an equal aggregate  principal amount of Capital Securities
of other authorized  denominations,  the Securities Registrar shall register the
transfer or make the exchange as requested if its  reasonable  requirements  for
such  transaction  are  met;  provided,  however,  that the  Capital  Securities
surrendered for transfer or exchange:

                           (A)  shall  be  duly  endorsed  or  accompanied  by a
                  written instrument of transfer in form reasonably satisfactory
                  to the Property  Trustee and the  Securities  Registrar,  duly
                  executed by the Purchaser or his attorney  duly  authorized in
                  writing,  delivered to the Depositor at least 30 Business Days
                  before such intended  transfer,  and the  Depositor  shall not
                  have  delivered a written notice of objection to the Purchaser
                  within 5 Business Days prior to the intended  transfer,  which
                  notice of  objection  shall  state  whether the  Depositor  is
                  objecting pursuant to subsection (D) or (E) below;

                           (B) in the case of Restricted  Securities,  are being
                  transferred  pursuant  to an  applicable  exemption  from  the
                  Securities Act and are accompanied by the following additional
                  information and documents:  a Restricted Security Certificate,
                  satisfactory to the Property  Trustee and duly executed by the
                  transferor  Holder or his attorney duly authorized in writing,
                  in the form  attached  hereto as  Exhibit  D (the  "Restricted
                  Securities   Certificate")  and  an  opinion  of  counsel  (as
                  described in subsection (c)(v) below) reasonably acceptable to
                  the  Depositor and to the  Securities  Registrar to the effect
                  that such transfer is in compliance  with the Securities  Act,
                  in which case the transferee Holder shall take delivery in the
                  form of a Restricted Security, subject to Section 5.4(c);

                           (C) shall be accompanied by a written  statement that
                  such transferee agrees to be bound by the terms and provisions
                  of this Trust Agreement and the Purchase Agreement;

                           (D) shall be subject to the right of the Depositor to
                  veto  the  Purchaser's  choice  of such  Person  to  whom  the
                  proposed  transfer or disposition is to occur by giving notice
                  of such  objection to the Purchaser as described in (A) above;
                  and

                           (E)  shall,  pursuant  to  Section  4.2(a)(iii),   be
                  subject  to the right of the  Depositor  to cause  the  Issuer
                  Trust  to send out a  notice  of  redemption  to  redeem  at a
                  Redemption  Price  specified in Section 11.7 of the Indenture,
                  the Security or


                                                        27





                  Securities  surrendered  for  transfer  or  exchange by giving
                  notice of such  objection to the Purchaser as described in (A)
                  above.

         (c)  Securities  Act Legends.  Except as set forth below,  Certificated
Capital  Securities,  their  respective  Successor  Securities and a new Capital
Security which is issued in exchange for another Capital Security or any portion
thereof,  upon transfer or otherwise,  shall bear a Restricted Securities Legend
as set forth in Section 5.11:

                  (i) at any time  after the  Capital  Securities  may be freely
         transferred  without  registration  under the Securities Act or without
         being subject to transfer  restrictions pursuant to the Securities Act,
         a new Capital  Security which does not bear a Securities Act Legend may
         be  issued in  exchange  for or in lieu of a  Capital  Security  or any
         portion thereof which bears such a legend if the Depositor has received
         from the Purchaser an opinion of counsel as described in subsection (v)
         below  and  if  the  Property  Trustee  has  received  an  Unrestricted
         Securities   Certificate,   in  the  form  of   Exhibit  E  hereto  (an
         "Unrestricted  Securities  Certificate"),  satisfactory to the Property
         Trustee  and duly  executed  by the  Holder  of such  legended  Capital
         Security or his attorney  duly  authorized  in writing,  and after such
         date and  receipt  of such  certificate,  the  Property  Trustee  shall
         authenticate and deliver such a new Capital Security in exchange for or
         in lieu of such other Capital Security as provided in this Article 5;

                  (ii) a new Capital  Security  which does not bear a Securities
         Act  Legend  may be  issued  in  exchange  for or in lieu of a  Capital
         Security or any portion  thereof which also does not bear such a legend
         if,  after the  receipt  by the  Depositor  of an opinion of counsel as
         described in subsection (v) below, in the Depositor's judgment, placing
         such a legend upon such new Capital Security is not necessary to ensure
         compliance  with the  registration  requirements of the Securities Act,
         and the Property  Trustee,  at the  direction of the  Depositor,  shall
         authenticate  and deliver  such a new  Capital  Security as provided in
         this Article 5; and

                  (iii)  the  Purchaser  agrees  that it  will  not  effect  the
         proposed  transfer or  disposition  of the Capital  Security until such
         Purchaser   has  provided  to  the  Depositor  an  opinion  of  counsel
         satisfactory  in form and substance to the Depositor that such proposed
         disposition  or  transfer  is  exempt  from   registration   under  the
         Securities Act and any applicable  state securities laws. The Depositor
         shall use its best  efforts to comply with any state  securities  laws,
         but shall in no event be required, in connection therewith,  to qualify
         to do business in any state where it is not then  qualified  or to take
         any action that would  subject it to tax or to the  general  service of
         process in any state where it is not then subject.

         (d) Any  purchaser or Holder of any Capital  Securities or any interest
therein will be deemed to have  represented by its purchase and holding  thereof
that it either  (i) is not a Plan or a Plan Asset  Entity and is not  purchasing
such Capital  Securities on behalf of or with "plan assets" of any Plan, or (ii)
is eligible for the exemptive relief available under PTCE 96-23, 95-


                                                        28





60, 91-38,  90-1 or 84-14 or another  applicable  exemption with respect to such
purchase or holding. The Securities Registrar may, and if the Depositor shall so
request,  the Securities  Registrar  shall,  before  registering for transfer or
exchange any Capital Securities Certificates as provided in Sections 5.2, 5.4 or
5.5 of this Trust Agreement, (A) require the purchaser or Holder of such Capital
Securities  Certificates  to confirm  that it either  (x) is not a Plan,  a Plan
Asset Entity or a Person  investing "plan assets" of any Plan or (y) is eligible
for the exemptive  relief  available  under PTCE 96-23,  95-60,  91-38,  90-1 or
84-14,  and (B) if such purchaser or Holder does not provide such  confirmation,
require an Opinion of Counsel or other evidence satisfactory to the Depositor of
the  availability  to such purchaser or Holder of another  applicable  exemption
with respect to such purchase or holding.

     SECTION  5.5.  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
Issuer 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  5.5,  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 5.5
shall constitute  conclusive evidence of an undivided beneficial interest in the
assets of the Issuer Trust  corresponding to that evidenced by the lost,  stolen
or destroyed Trust Securities  Certificate,  as if originally issued, whether or
not the lost, stolen or destroyed Trust Securities Certificate shall be found at
any time.

         SECTION 5.6. Persons Deemed Holders.

         The Issuer  Trustees and the Securities  Registrar shall each 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
none of the Issuer  Trustees and the Securities  Registrar shall be bound by any
notice to the contrary.

         SECTION 5.7. Access to List of Holders' Names and Addresses.

         Each  Holder and each Owner  shall be deemed to have agreed not to hold
the Depositor or the Issuer Trustees  accountable by reason of the disclosure of
its name and address,  regardless of the source from which such  information was
derived.


                                                        29






         SECTION 5.8. Maintenance of Office or Agency.

         The  Administrative  Trustees  shall  maintain  an office or offices or
agency or agencies where Capital Securities  Certificates may be surrendered for
registration  of transfer or exchange  and where  notices and demands to or upon
the  Issuer  Trustees  in respect of the Trust  Securities  Certificates  may be
served.  The Administrative  Trustees  initially  designate HSB Group, Inc., One
State  Street,  Hartford,  Connecticut  06102 as its  office and agency for such
purposes.  The  Administrative  Trustees shall give prompt written notice to the
Depositor, the Property Trustee and to the Holders of any change in the location
of the Securities Register or any such office or agency.

         SECTION 5.9. Appointment of Paying Agents.

         The Paying Agent or Agents shall make Distributions to Holders 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 solely for the
purpose  of making  the  Distributions  referred  to above.  The  Administrative
Trustees  may  revoke  such  power  and  remove  the  Paying  Agent  in its sole
discretion. The Paying Agent shall initially be the Bank and any co-paying agent
chosen by the Property Trustee 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 and the
Property Trustee. If 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 (which shall be a bank or trust company) that
is reasonably acceptable to the Depositor to act as Paying Agent. Such successor
Paying Agent or any  additional  Paying  Agent shall  execute and deliver to the
Issuer Trustees an instrument in which such successor Paying Agent or additional
Paying Agent shall agree with the Issuer  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  Holders in trust for the  benefit of the Holders
entitled thereto until such sums shall be paid to such Holders. 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 8.1, 8.3 and 8.6 herein 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 5.10. Ownership of Common Securities by Depositor.

         On the Closing Date, the Depositor shall acquire,  and thereafter shall
retain,  beneficial and record ownership of the Common  Securities.  Neither the
Depositor nor any successor  Holder of the Common  Securities  may transfer less
than all the Common Securities (except in connection with a redemption thereof),
and  the  Depositor  or any  such  successor  Holder  may  transfer  the  Common
Securities only (i) in connection with a consolidation or merger of the


                                                        30





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 8.1 of the Indenture, or (ii) to the Depositor or an
Affiliate of the Depositor in compliance  with  applicable  law  (including  the
Securities  Act and  applicable  state  securities  and blue sky  laws).  To the
fullest extent permitted by law, any attempted transfer of the Common Securities
other  than as set  forth in the next  proceeding  sentence  shall be void.  The
Administrative Trustees shall cause each Common Securities Certificate issued to
the Depositor to contain a legend stating substantially "THIS CERTIFICATE IS NOT
TRANSFERABLE  EXCEPT  TO THE  DEPOSITOR  OR AN  AFFILIATE  OF THE  DEPOSITOR  IN
COMPLIANCE WITH APPLICABLE LAW AND SECTION 5.10 OF THE TRUST AGREEMENT."

         SECTION 5.11. Restrictive Legends.

         The Capital Securities Certificate shall bear the following legend (the
"Restricted  Securities  Legend") unless the Depositor  determines  otherwise in
accordance with applicable law:

                  "THE CAPITAL  SECURITIES  EVIDENCED  HEREBY,  ANY  CONVERTIBLE
         SUBORDINATED  DEFERRABLE  INTEREST DEBENTURES ISSUABLE HEREWITH AND THE
         COMMON STOCK ISSUABLE UPON THEIR  CONVERSION  HAVE NOT BEEN  REGISTERED
         UNDER THE U.S.  SECURITIES ACT OF 1933 (THE  "SECURITIES  ACT") AND MAY
         NOT BE OFFERED,  SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN WHOLE
         OR IN PART (BUT IF IN PART,  IN AMOUNTS  NOT LESS THAN  $10,000,000  IN
         PRINCIPAL  AMOUNT) AND ONLY IN COMPLIANCE WITH THE  REQUIREMENTS OF THE
         SECURITIES ACT OR PURSUANT TO AN APPLICABLE EXEMPTION THEREFROM."

         SECTION 5.12. Rights of Holders; Waivers of Past Defaults.

         (a) The legal title to the Trust Property is vested  exclusively in the
Property  Trustee (in its capacity as such) in accordance  with Section 2.9, and
the Holders  shall not have any right or title  therein other than the undivided
beneficial  interest in the assets of the Issuer 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 Issuer 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 Holders against
payment of the purchase price therefor will be fully paid and  nonassessable  by
the Issuer 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 Capital 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


                                                        31





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
Liquidation  Amount of the Capital  Securities then  Outstanding  shall have the
right to make such  declaration by a notice in writing to the Property  Trustee,
the Depositor and the Debenture Trustee.

         At any time after a  declaration  of  acceleration  with respect to the
Debentures  has been made and  before a judgment  or decree  for  payment of the
money  due has  been  obtained  by the  Debenture  Trustee  as  provided  in the
Indenture, if the Property Trustee fails to annul any such declaration and waive
such default,  the Holders of at least a Majority in  Liquidation  Amount of the
Capital Securities, by written notice to the Property Trustee, the Depositor and
the  Debenture  Trustee,   may  rescind  and  annul  such  declaration  and  its
consequences if:

                  (i) the  Depositor  has paid or deposited  with the  Debenture
         Trustee a sum sufficient to pay:

                         (A) all overdue  installments of interest on all of the
                  Debentures,

                           (B) the  principal of (and  premium,  if any, on) any
                  Debentures  that  have  become  due  otherwise  than  by  such
                  declaration of acceleration  and interest  thereon at the rate
                  borne by the Debentures, and

                           (C)  all  sums  paid  or  advanced  by the  Debenture
                  Trustee under the Indenture and the  reasonable  compensation,
                  expenses,  disbursements and advances of the Debenture Trustee
                  and the Property Trustee, their agents and counsel; and

                  (ii) all Events of  Default  with  respect to the  Debentures,
         other than the  non-payment of the principal of the Debentures that has
         become  due solely by such  acceleration,  have been cured or waived as
         provided in Section 5.13 of the Indenture.

         The Holders of at least a Majority in Liquidation Amount of the Capital
Securities may, on behalf of the Holders of all the Trust Securities,  waive any
past default or Event of Default under the Indenture,  except a default or Event
of Default in the payment of principal or interest (unless such default or Event
of Default has been cured and a sum  sufficient to pay all matured  installments
of interest and principal due otherwise than by acceleration  has been deposited
with the  Debenture  Trustee)  or a default  or Event of Default in respect of a
covenant or  provision  that under the  Indenture  cannot be modified or amended
without  the  consent  of the  holder  of each  outstanding  Debenture.  No such
rescission  shall affect any subsequent  default or impair any right  consequent
thereon.

         Upon receipt by the Property  Trustee of written notice  declaring such
an acceleration,  or rescission and annulment thereof, by Holders of any part of
the Capital  Securities,  a record  date shall be  established  for  determining
Holders of Outstanding Capital Securities entitled to join in such notice, which
record date shall be at the close of business  on the day the  Property  Trustee
receives such notice.  The Holders on such record date, or their duly designated
proxies,


                                                        32





and only such Persons,  shall be entitled to join in such notice, whether or not
such Holders remain Holders after such record date; provided,  that, unless such
declaration of  acceleration,  or rescission and annulment,  as the case may be,
shall have become effective by virtue of the requisite  percentage having joined
in such  notice  prior to the day that is 90 days after such record  date,  such
notice of declaration of acceleration,  or rescission and annulment, as the case
may be, shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder,  from giving,  after  expiration of such 90-day period, a new
written  notice of  declaration  of  acceleration,  or rescission  and annulment
thereof, as the case may be, that is identical to a written notice that has been
canceled pursuant to the proviso to the preceding sentence, in which event a new
record date shall be  established  pursuant to the  provisions  of this  Section
5.12(b).

         (c) For so long as any Capital  Securities remain  Outstanding,  to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(1)
or 5.1(2) of the  Indenture,  any  Holder of Capital  Securities  shall have the
right to  institute a proceeding  directly  against the  Depositor,  pursuant to
Section 5.9 of the Indenture,  for  enforcement of payment to such Holder of any
amounts payable in respect of Debentures  having an aggregate  principal  amount
equal to the  aggregate  Liquidation  Amount of the Capital  Securities  of such
Holder (a  "Direct  Action").  Except as set forth in Section  5.12(b)  and this
Section  5.12(c),  the  Holders  of  Capital  Securities  shall have no right to
exercise directly any right or remedy available to the holders of, or in respect
of, the Debentures.

         (d) Except as otherwise provided in paragraphs (a), (b) and (c) of this
Section 5.12,  the Holders of at least a Majority in  Liquidation  Amount of the
Capital  Securities  may, on behalf of the Holders of all the Trust  Securities,
waive any past  default  or Event of  Default  and its  consequences.  Upon such
waiver,  any such  default or Event of  Default  shall  cease to exist,  and any
default  or Event of  Default  arising  therefrom  shall be  deemed to have been
cured,  for every  purpose of this Trust  Agreement,  but no such  waiver  shall
extend to any  subsequent  or other  default  or Event of  Default or impair any
right consequent thereon.


                                   ARTICLE VI

                        ACTS OF HOLDERS; MEETINGS; VOTING

         SECTION 6.1. Limitations on Voting Rights.

         (a) Except as  expressly  provided in this Trust  Agreement  and in the
Indenture  and as  otherwise  required by law,  no Holder of Capital  Securities
shall  have  any  right  to  vote  or  in  any  manner  otherwise   control  the
administration,  operation and management of the Issuer 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
Holders from time to time as partners or members of an association.


                                                        33






         (b) So long as any  Debentures  are  held by the  Property  Trustee  on
behalf of the Issuer Trust,  the Property Trustee shall not (i) direct the time,
method and place of conducting any  proceeding  for any remedy  available to the
Debenture  Trustee,  or execute  any trust or power  conferred  on the  Property
Trustee with respect to the Debentures,  (ii) waive any past default that may be
waived under Section 5.13 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 the Capital 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 Capital  Securities.
The  Property  Trustee  shall not  revoke any action  previously  authorized  or
approved  by a vote  of the  Holders  of the  Capital  Securities,  except  by a
subsequent vote of the Holders of the Capital  Securities.  The Property Trustee
shall  notify all  Holders of the  Capital  Securities  of any notice of default
received with respect to the Debentures.  In addition to obtaining the foregoing
approvals of the Holders of the Capital  Securities,  prior to taking any of the
foregoing  actions,  the Issuer Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that such
action  shall not cause the  Issuer  Trust to be  taxable  as a  corporation  or
classified as other than a grantor trust for United  States  Federal  income tax
purposes.

         (c) If any proposed  amendment to the Trust Agreement  provides for, or
the Issuer  Trustees  otherwise  propose to  effect,  (i) any action  that would
adversely  affect in any  material  respect the powers,  preferences  or special
rights of the  Capital  Securities,  whether  by way of  amendment  to the Trust
Agreement or otherwise,  or (ii) the  dissolution,  winding-up or termination of
the Issuer Trust, other than pursuant to the terms of this Trust Agreement, then
the Holders of  Outstanding  Capital  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  Capital  Securities.   Notwithstanding  any  other
provision of this Trust  Agreement,  no amendment to this Trust Agreement may be
made if, as a result of such  amendment,  it would cause the Issuer  Trust to be
taxable as a corporation  or classified as other than a grantor trust for United
States Federal income tax purposes.

         SECTION 6.2. Notice of Meetings.

         Notice  of all  meetings  of the  Holders  of the  Capital  Securities,
stating  the  time,  place and  purpose  of the  meeting,  shall be given by the
Property Trustee pursuant to Section 10.8 to each Holder of Capital  Securities,
at such Holder's  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.



                                                        34





         SECTION 6.3. Meetings of Holders of the Capital Securities.

         No annual meeting of Holders is required to be held. The Administrative
Trustees, however, shall call a meeting of the Holders of the Capital Securities
to vote on any matter upon the written request of the Holders of at least 25% in
aggregate  Liquidation  Amount of the  Outstanding  Capital  Securities  and the
Administrative  Trustees  or the  Property  Trustee  may,  at any  time in their
discretion,  call a meeting of the Holders of the Capital  Securities to vote on
any matters as to which such Holders are entitled to vote.

         The Holders of at least a Majority in Liquidation Amount of the Capital
Securities,  present  in person or by proxy,  shall  constitute  a quorum at any
meeting of the Holders of the Capital Securities.

         If a quorum is present at a meeting, an affirmative vote by the Holders
present, in person or by proxy, holding Capital Securities representing at least
a majority of the aggregate Liquidation Amount of the Capital Securities held by
the  Holders  present,  either  in person or by  proxy,  at such  meeting  shall
constitute  the action of the  Holders of the  Capital  Securities,  unless this
Trust Agreement requires a greater number of affirmative votes.

         SECTION 6.4. Voting Rights.

         Holders  shall be entitled  to one vote for each $1,000 of  Liquidation
Amount  represented  by their  Outstanding  Trust  Securities  in respect of any
matter as to which such Holders are entitled to vote.

         SECTION 6.5. Proxies, etc.

         At any meeting of Holders, any Holder 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 Issuer 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
Holders 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 Holder 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.



                                                        35





         SECTION 6.6. Holder Action by Written Consent.

         Any action  that may be taken by Holders  of  Capital  Securities  at a
meeting may be taken without a meeting if Holders holding at least a Majority in
Liquidation Amount of the Capital Securities entitled to vote in respect of such
action (or such  larger  proportion  thereof as shall be  required  by any other
provision of this Trust Agreement)  shall consent to the action in writing.  Any
action that may be taken by the Holder of all the Common Securities may be taken
if such Holder shall consent to the action in writing.

         SECTION 6.7. Record Date for Voting and Other Purposes.

         For the purposes of determining  the Holders 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  Holders 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 Holders of record for such purposes.

         SECTION 6.8. Acts of Holders.

         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 Holders may be embodied in and evidenced by one or more  instruments
of  substantially  similar tenor signed by such Holders 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 Holders  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
8.1) conclusive in favor of the Issuer Trustees,  if made in the manner provided
in this Section 6.8.

         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 such signer's individual capacity, such
certificate or affidavit shall also constitute sufficient proof of such signer's
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 that any Issuer Trustee receiving the same deems sufficient.

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


                                                        36






         Any request, demand, authorization,  direction, notice, consent, waiver
or other Act of the Holder of any Trust  Security shall bind every future Holder
of the same Trust  Security and the Holder 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 Issuer
Trustees, the Depositor or the Issuer Trust in reliance thereon,  whether or not
notation of such action is made upon such Trust Security.

         Without limiting the foregoing, a Holder 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  among the Holders or the Issuer  Trustees
with  respect to the  authenticity,  validity or binding  nature of any request,
demand, authorization, direction, consent, waiver or other Act of such Holder or
Issuer Trustee under this Article VI, then the  determination  of such matter by
the Property Trustee shall be conclusive with respect to such matter.

         SECTION 6.9. Inspection of Records.

         Upon reasonable notice to the Administrative  Trustees and the Property
Trustee,  the records of the Issuer Trust shall be open to inspection by Holders
(and  other  Issuer  Trustees)  during  normal  business  hours for any  purpose
reasonably  related  to such  Holder's  interest  as a Holder  (or  such  Issuer
Trustee's service as a Trustee hereunder).

Trustee or the  Delaware  Trustee,  as the case may be, to enter into or perform
its obligations as one of the Issuer Trustees under this Trust Agreement.


                                                        38






         SECTION 7.2. Representations and Warranties of Depositor.

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

         (a) the Trust  Securities  Certificates  issued on the Closing  Date on
behalf of the Issuer Trust have been duly authorized and will have been duly and

                                  ARTICLE VIII

                       THE ISSUER TRUSTEES; PAYING AGENTS

         SECTION 8.1. Certain Duties and Responsibilities.

         (a) The duties and  responsibilities of the Issuer Trustees shall be as
provided  by this Trust  Agreement  and,  in the case of the  Property  Trustee,
subject to the Trust Indenture Act.  Notwithstanding the foregoing,  but subject
to Section 8.1(c) and 8.1(e), no provision of this Trust Agreement shall require
any of the Issuer Trustees to expend or risk its or their own funds or otherwise
incur any financial  liability in the  performance of any of its or their duties
hereunder,  or in the exercise of any of its or their rights or powers, if it or
they shall have reasonable grounds for believing that repayment of such funds or
adequate  indemnity against such risk or liability is not reasonably  assured to
it or them.  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 Issuer  Trustees shall be subject to the provisions
of this  Section  8.1.  Nothing in this Trust  Agreement  shall be  construed to
release  an  Administrative  Trustee  from  liability  for his or her own  gross
negligent  action,  his or her own gross negligent failure to act, or his or her
own wilful  misconduct.  To the  extent  that,  at law or in  equity,  an Issuer
Trustee  has  duties and  liabilities  relating  to the  Issuer  Trust or to the
Holders,  such Issuer  Trustee shall not be liable to the Issuer Trust or to any
Holder for such Issuer  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 Issuer Trustees otherwise existing at
law or in equity,  are agreed by the  Depositor  and the Holders to replace such
other duties and liabilities of the Issuer 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


                                                        39





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 Holder,  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 Issuer  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  8.1(b)  does not limit the
liability of the Issuer  Trustees  expressly  set forth  elsewhere in this Trust
Agreement or, in the case of the Property Trustee, in the Trust Indenture Act.

         (c) If an Event of Default has occurred and is continuing, the Property
Trustee shall enforce this Trust Agreement for the benefit of the Holders.

         (d) The Property Trustee, before the occurrence of any Event of Default
and after the  curing of all  Events of Default  that may have  occurred,  shall
undertake  to perform  only such  duties as are  specifically  set forth in this
Trust Agreement  (including pursuant to Section 10.10), and no implied covenants
shall be read into this Trust  Agreement  against the  Property  Trustee.  If an
Event of Default  has  occurred  (that has not been cured or waived  pursuant to
Section 5.12), the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust 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.

         (e) 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 wilful 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  Property
                  Trustee shall be determined  solely by the express  provisions
                  of this Trust Agreement (including pursuant to Section 10.10),
                  and the Property  Trustee  shall not be liable  except for the
                  performance of such duties and obligations as are specifically
                  set  forth in this  Trust  Agreement  (including  pursuant  to
                  Section 10.10); and

                           (B) in the  absence  of bad  faith on the part of the
                  Property Trustee,  the Property Trustee may conclusively rely,
                  as to the truth of the statements  and the  correctness of the
                  opinions expressed therein,  upon any certificates or opinions
                  furnished  to  the  Property  Trustee  and  conforming  to the
                  requirements of this Trust  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 Property Trustee,  the Property Trustee shall
                  be under a duty to examine  the same to  determine  whether or
                  not they conform to the requirements of this Trust Agreement.


                                                        40






                  (ii) 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;

                  (iii) 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 at least a Majority in
         Liquidation  Amount of the  Capital  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;

                  (iv) 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;

                  (v) 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
         3.1 and except to the extent otherwise required by law; and

                  (vi)  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
         any other Issuer Trustee or the Depositor;

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

         SECTION 8.2. Certain Notices.

         Within  thirty (30) 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 10.8,  notice of such Event of
Default to the  Holders  and the  Administrative  Trustee,  unless such Event of
Default shall have been cured or waived.



                                                        41





         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, the Property Trustee shall transmit, in the manner and to the extent
provided  in  Section  10.8,  notice of such  exercise  to the  Holders  and the
Administrative Trustees, unless such exercise shall have been revoked.

         The Property Trustee shall not be deemed to have knowledge of any Event
of Default unless the Property Trustee shall have received written notice,  or a
Responsible  Officer  charged with the  administration  of this Trust  Agreement
shall have obtained actual knowledge, of such Event of Default.

         SECTION 8.3. Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (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,
(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 Holders of the Capital  Securities  are  entitled to vote under the terms of
this  Trust  Agreement,  the  Property  Trustee  shall  deliver  a notice to the
Depositor  requesting the  Depositor's  opinion 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 Holders, in which event
the  Property  Trustee  shall  have no  liability  except for its own bad faith,
negligence or wilful misconduct;

         (c) any  direction or act of the Depositor  contemplated  by this Trust
Agreement shall be sufficiently evidenced by an Officers' Certificate;

         (d) any direction or act of an Administrative  Trustee  contemplated by
this Trust Agreement shall be sufficiently  evidenced by a certificate  executed
by such Administrative Trustee and setting forth such direction or act;


                                                        42






         (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 re-registration 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 Holders  pursuant to this Trust  Agreement,  unless such
Holders  shall have  offered to the  Property  Trustee  reasonable  security  or
indemnity against the costs,  expenses and liabilities that might be incurred by
it in  compliance  with  such  request  or  direction;  provided  that,  nothing
contained in this Section 8.3(g) shall be taken to relieve the Property Trustee,
upon the  occurrence of an Event of Default,  of its  obligation to exercise the
rights and powers vested in it by this Trust Agreement;

         (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  Holders,  but the Property
Trustee  may make such  further  inquiry  or  investigation  into such  facts or
matters as it may see fit;

         (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 be responsible for
its own negligence,  bad faith or wilful misconduct with respect to selection of
any agent or attorney appointed by it hereunder;

         (j) whenever in the administration of this Trust Agreement the 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 (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
terms of the Trust Securities in respect of such remedy, right or action),  (ii)
may refrain  from  enforcing  such  remedy or right or taking such other  action
until such instructions are received,  and (iii) shall be protected in acting in
accordance with such instructions; and

         (k) except as otherwise expressly provided by this Trust Agreement, the
Property  Trustee  shall not be under any  obligation to take any action that is
discretionary under the provisions of this Trust Agreement.


                                                        43






         No provision of this Trust Agreement shall be deemed to impose any duty
or obligation  on any Issuer  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 it 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 any Issuer Trustee shall be construed to be a duty.

         SECTION 8.4. Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Trust Securities  Certificates
shall be taken as the statements of the Depositor and the Issuer Trust,  and the
Issuer  Trustees do not assume any  responsibility  for their  correctness.  The
Issuer  Trustees  shall not be  accountable  for the use or  application  by the
Depositor of the proceeds of the Debentures.

         The Property Trustee may conclusively  assume that any funds held by it
hereunder  are  legally  available  unless an  officer of the  Property  Trustee
assigned to its Corporate Trust division shall have received written notice from
the  Depositor,  any Holder or any other Issuer  Trustee that such funds are not
legally available.

         SECTION 8.5. May Hold Securities.

         Any Issuer  Trustee  or any agent of any  Issuer  Trustee or the Issuer
Trust, in its individual or any other capacity,  may become the owner or pledgee
of Trust  Securities  and,  subject  to  Sections  8.8 and 8.13  and,  except as
provided in the definition of the term "Outstanding" in Article I, may otherwise
deal with the Issuer  Trust with the same rights it would have if it were not an
Issuer Trustee or such agent.

         SECTION 8.6. Compensation; Indemnity; Fees.

         The Depositor agrees:

         (a) to pay to each Issuer  Trustee  and Paying  Agent from time to time
such reasonable  compensation for all services rendered by them hereunder as may
be agreed by the Depositor and such Issuer Trustee or Paying Agent,  as the case
may be,  from  time to time  (which  compensation  shall not be  limited  by any
provision  of law in  regard to the  compensation  of a  trustee  of an  express
trust);

         (b) except as otherwise  expressly  provided herein,  to reimburse each
Issuer  Trustee  and Paying  Agent upon  request  for all  reasonable  expenses,
disbursements  and advances  incurred or made by each Issuer  Trustee and Paying
Agent in accordance  with any provision of this Trust  Agreement  (including the
reasonable  compensation and the expenses and  disbursements of their agents and
counsel),   except  any  such  expense,   disbursement  or  advance  as  may  be
attributable to their negligence, bad faith or wilful misconduct; and



                                                        44





         (c) to the fullest extent permitted by applicable law, to indemnify and
hold  harmless  (i) each  Issuer  Trustee,  (ii) each  Paying  Agent,  (iii) any
Affiliate  of any  Issuer  Trustee,  (iv) any  officer,  director,  shareholder,
employee, representative or agent of any Issuer Trustee, and (v) any employee or
agent of the Issuer Trust (referred to herein as an  "Indemnified  Person") from
and against any loss, damage,  liability,  tax, penalty, expense or claim of any
kind or nature whatsoever  incurred by such Indemnified  Person by reason of the
creation,  operation or  termination  of the Issuer Trust or any act or omission
performed or omitted by such  Indemnified  Person in good faith on behalf of the
Issuer Trust and in a manner such Indemnified  Person reasonably  believed to be
within the scope of authority conferred on such Indemnified Person by this Trust
Agreement, except that no Indemnified Person shall be entitled to be indemnified
in respect of any loss,  damage or claim incurred by such Indemnified  Person by
reason of negligence,  bad faith or wilful  misconduct with respect to such acts
or omissions.

         (d) to the fullest  extent  permitted  by  applicable  law, the parties
intend that Section 3561 of Title 12 of the Delaware Code shall not apply to the
Issuer Trust and that  compensation  payable to any Issuer  Trustee  pursuant to
this  Section  8.6 not be subject to review by any court under  Section  3560 of
Title 12 of the Delaware Code or otherwise.

         The  provisions  of this Section 8.6 shall survive the  termination  of
this Trust Agreement and the resignation or removal of any Issuer Trustee.

         No  Issuer  Trustee  or  Paying  Agent  may claim any Lien on any Trust
Property as a result of any amount due pursuant to this Section 8.6.

         The Depositor,  any Issuer Trustee  (subject to Section 8.8(a)) and any
Paying Agent may engage in or possess an interest in other business  ventures of
any nature or description,  independently or with others,  similar or dissimilar
to the  business of the Issuer  Trust,  and the Issuer  Trust and the Holders of
Trust  Securities  shall have no rights by virtue of this Trust Agreement in and
to such independent ventures or the income or profits derived therefrom, and the
pursuit of any such venture, even if competitive with the business of the Issuer
Trust,  shall not be deemed  wrongful or improper.  Neither the  Depositor,  any
Paying Agent nor any Issuer Trustee shall be obligated to present any particular
investment or other  opportunity to the Issuer Trust even if such opportunity is
of a character  that,  if presented to the Issuer  Trust,  could be taken by the
Issuer Trust,  and the  Depositor,  any Issuer Trustee or any Paying Agent shall
have the right to take for its own  account  (individually  or as a  partner  or
fiduciary)  or to recommend to others any such  particular  investment  or other
opportunity.  Any Issuer  Trustee or Paying Agent may engage or be interested in
any  financial or other  transaction  with the Depositor or any Affiliate of the
Depositor,  or may act as  depository  for,  trustee or agent for, or act on any
committee  or body  of  holders  of,  securities  or  other  obligations  of the
Depositor or its Affiliates.

     SECTION 8.7.  Corporate  Property Trustee  Required;  Eligibility of Issuer
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
a national or state chartered bank and


                                                        45





eligible pursuant to the Trust Indenture Act to act as such, and that has at the
time of such  appointment  securities  rated in one of the three highest  rating
categories by a nationally  recognized  statistical  rating  organization  and 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 8.7 and to the extent  permitted by the Trust  Indenture  Act, 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  8.7,  it shall  resign  immediately  in the  manner and with the effect
hereinafter specified in this Article. At the time of appointment,  the Property
Trustee must have securities rated in one of the three highest rating categories
by a nationally recognized statistical rating organization.

         (b)  There  shall at all times be one or more  Administrative  Trustees
hereunder.  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  hereunder.  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 and that shall act through one or
more persons authorized to bind such entity.

         SECTION 8.8. Conflicting Interests.

         (a) 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.

         (b) The Guarantee  Agreement  and the  Indenture  shall be deemed to be
specifically described in this Trust Agreement for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

         SECTION 8.9. 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 may at the time be located,  Depositor and the Administrative Trustees,
by agreed  action of the majority of them shall have power to appoint,  and upon
the written  request of the  Administrative  Trustee and 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


                                                        46





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  8.9.  Any
co-trustee  or separate  trustee  appointed  pursuant to this  Section 8.9 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. If an Event of Default under the Indenture shall have occurred
and be continuing,  the Property Trustee alone shall have the power to make such
appointment.

         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   by  one  or  more
Administrative  Trustees,  and the Trust  Securities  shall be  delivered by the
Property Trustee, 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  Property  Trustee  specified
hereunder  shall be  exercised  solely by the  Property  Trustee 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 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  8.9,  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
resigning  or removed may be  appointed  in the manner  provided in this Section
8.9.


                                                        47






         (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 8.10. Resignation and Removal; Appointment of Successor.

         No  resignation  or  removal  of  any  Issuer  Trustee  (the  "Relevant
Trustee") and no  appointment  of a successor  Issuer  Trustee  pursuant to this
Article  shall become  effective  until the  acceptance  of  appointment  by the
successor  Issuer  Trustee in accordance  with the  applicable  requirements  of
Section 8.11.

         Subject to the immediately  preceding  paragraph,  the Relevant Trustee
may resign at any time by giving written  notice thereof to the Holders.  If the
instrument of acceptance by the  successor  Issuer  Trustee  required by Section
8.11 shall not have been delivered to the Relevant  Trustee within 60 days after
the giving of such notice of resignation,  the Relevant Trustee may petition, at
the  expense  of the  Depositor,  any court of  competent  jurisdiction  for the
appointment of a successor Relevant Trustee.

         Unless  a  Debenture  Event  of  Default  shall  have  occurred  and be
continuing,  any Issuer  Trustee may be removed at any time by Act of the Holder
of the Common  Securities.  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 Capital Securities,  delivered to the Relevant Trustee
(in its individual  capacity and, in the case of the Property Trustee, on behalf
of the  Issuer  Trust).  An  Administrative  Trustee  may only be removed by the
Holder of the Common Securities and may be so removed at any time.

         If any Issuer Trustee shall resign,  be removed or become  incapable of
acting  as Issuer  Trustee,  or if a vacancy  shall  occur in the  office of any
Issuer Trustee for any cause, at a time when no Debenture Event of Default shall
have occurred and be  continuing,  the Holder of the Common  Securities,  by Act
delivered to the retiring  Issuer  Trustee,  shall promptly  appoint a successor
Issuer  Trustee or Issuer  Trustees,  and such  successor  Issuer  Trustee shall
comply with the applicable requirements of Section 8.11. 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  Holders  of  Capital  Securities,  by Act of the  Holders of a
Majority  in  Liquidation  Amount of the  Capital  Securities  delivered  to the
retiring Relevant Trustee,  shall promptly appoint a successor  Relevant Trustee
or Trustees,  and such successor Issuer Trustee shall comply with the applicable
requirements of Section 8.11. If an


                                                        48





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 Holder of the Common Securities by Act delivered
to the Administrative Trustee shall promptly appoint a successor  Administrative
Trustee or Administrative Trustees and such successor  Administrative Trustee or
Trustees  shall comply with the applicable  requirements  of Section 8.11. If no
successor  Relevant  Trustee  shall have been so  appointed by the Holder of the
Common  Securities  or the  Holders of a Majority in  Liquidation  Amount of the
Capital Securities,  as the case may be, and accepted  appointment in the manner
required by Section 8.11,  any Holder who has been a Holder of Trust  Securities
for at least six months may,  on behalf of such Holder and all others  similarly
situated,  or any other  Issuer  Trustee,  may  petition  any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

         The Property  Trustee  shall give notice of each  resignation  and each
removal of an Issuer Trustee and each  appointment of a successor Issuer Trustee
to all Holders in the manner  provided in Section  10.8 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,  if any 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 the  remaining  Administrative  Trustees if there are at least two of them or
(b) otherwise by the Depositor (with the successor in either case being a Person
who satisfies the eligibility  requirement for the Delaware Trustee set forth in
Section 8.7).

         SECTION 8.11. Acceptance of Appointment by Successor.

         In case of the appointment  hereunder of a successor  Relevant Trustee,
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 Issuer 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 Issuer  Trust by more than one  Relevant
Trustee,  it being  understood  that nothing herein or in such  amendment  shall
constitute  such  Relevant  Trustees  co-trustees  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;  but, on request of the Issuer Trust or any successor Relevant
Trustee such retiring  Relevant Trustee shall duly assign,  transfer and deliver
to such successor Relevant


                                                        49





Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant  Trustee  hereunder with respect to the Trust Securities and the Issuer
Trust.

         Upon  request of any  Issuer  Trustee  or any such  successor  Relevant
Trustee,  the retiring Relevant Trustee or the Issuer Trust, as the case may be,
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 8.12. Merger, Conversion, Consolidation or Succession to Business.

         Any Person into which the Property  Trustee or the Delaware Trustee may
be merged or  converted  or with  which it may be  consolidated,  or any  Person
resulting from any merger,  conversion or  consolidation  to which such Relevant
Trustee shall be a party, or any Person,  succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant  Trustee  hereunder,  provided that such Person 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 8.13. Preferential Collection of Claims Against Depositor or Issuer
Trust.

         If and when the Property  Trustee  shall be or become a creditor of the
Depositor  or  the  Issuer  Trust  (or  any  other   obligor  upon  the  Capital
Securities),  the Property  Trustee  shall be subject to the  provisions  of the
Trust  Indenture Act regarding the collection of claims against the Depositor or
the Issuer Trust (or any such other obligor).

         SECTION 8.14. Property Trustee May File Proofs of Claim.

         In  case  of any  receivership,  insolvency,  liquidation,  bankruptcy,
reorganization,  arrangement,  adjustment, composition or other similar judicial
proceeding  relative  to the Issuer  Trust or any other  obligor  upon the Trust
Securities or the property of the Issuer Trust or of such other obligor or their
creditors,  the Property Trustee  (irrespective of whether any  Distributions on
the Trust  Securities  shall then be due and payable and irrespective of whether
the  Property  Trustee  shall have made any  demand on the Issuer  Trust for the
payment of any past due Distributions)  shall be entitled and empowered,  to the
fullest  extent  permitted  by  law,  by  intervention  in  such  proceeding  or
otherwise:

         (a) to file and prove a claim for the whole amount of any Distributions
owing and  unpaid in  respect  of the Trust  Securities  and to file such  other
papers or documents as may be necessary or advisable in order to have the claims
of the Property Trustee (including any claim for the


                                                        50





reasonable  compensation,  expenses,  disbursements and advances of the Property
Trustee,  its agents and  counsel) and of the Holders  allowed in such  judicial
proceeding, and

         (b) to collect  and  receive  any moneys or other  property  payable or
deliverable on any such claims and to distribute the same;

and any custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator or
other similar official in any such judicial  proceeding is hereby  authorized by
each Holder to make such payments to the Property  Trustee and, in the event the
Property  Trustee shall  consent to the making of such payments  directly to the
Holders,  to pay to the  Property  Trustee any amount due it for the  reasonable
compensation,  expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

         Nothing  herein  contained  shall be deemed to  authorize  the Property
Trustee  to  authorize  or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement adjustment or compensation affecting the
Trust  Securities  or the  rights of any  Holder  thereof  or to  authorize  the
Property  Trustee  to vote in  respect  of the  claim of any  Holder in any such
proceeding.

         SECTION 8.15. Reports by Property Trustee.

         (a) Not later  than 60 days  following  May 15 of each year  commencing
with May 15,  1998,  the  Property  Trustee  shall  transmit  to all  Holders in
accordance  with Section 10.8, and to the Depositor,  a brief report dated as of
the immediately preceding December 31 with respect to:

                  (i) its eligibility under Section 8.7 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 May 15 or, if the  Property
         Trustee has not complied in any material respect with such obligations,
         a description of such noncompliance; and

                  (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 Holders 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.


                                                        51






         (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 stock 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 8.16. Reports to the Property Trustee.

         Each of the Depositor and the Administrative  Trustees on behalf of the
Issuer Trust shall provide to the Property  Trustee such documents,  reports and
information  as required by Section 314 of the Trust  Indenture Act (if any) and
the compliance certificate required by Section 314(a) of the Trust Indenture Act
in the form, in the manner and at the times required by Section 314 of the Trust
Indenture  Act. The Depositor and the  Administrative  Trustees on behalf of the
Issuer  Trust  shall  annually  file with the  Property  Trustee  a  certificate
specifying  whether  such  Person  is in  compliance  with all of the  terms and
covenants applicable to such Person hereunder.

         SECTION 8.17. Evidence of Compliance with Conditions Precedent.

         Each of the Depositor and the Administrative  Trustees on behalf of the
Issuer Trust shall  provide to the Property  Trustee such evidence of compliance
with any conditions precedent, if any, provided for in this Trust Agreement that
relate to any of the matters set forth in Section 314(c) of the Trust  Indenture
Act. Any certificate or opinion  required to be given by an officer  pursuant to
Section  314(c)(1) of the Trust  Indenture  Act shall be given in the form of an
Officers' Certificate.

         SECTION 8.18. Number of Issuer Trustees.

         (a) The initial number of Issuer Trustees shall be five,  provided that
the  Property  Trustee  and the  Delaware  Trustee may be the same Person if the
Property Trustee satisfies the applicable requirements.

         (b) If an  Issuer  Trustee  ceases to hold  office  for any  reason,  a
vacancy  shall  occur.  The  vacancy  shall be  filled  with an  Issuer  Trustee
appointed in accordance with Section 8.10.

         (c)  The   death,   resignation,   retirement,   removal,   bankruptcy,
incompetence  or incapacity to perform the duties of an Issuer Trustee shall not
operate to annul, dissolve or terminate the Issuer Trust.

         SECTION 8.19. Delegation of Power.

         (a) Any Administrative  Trustee,  by power of attorney  consistent with
applicable  law,  delegate to any other  natural  person over the age of 21 such
Administrative  Trustee's  power for the  purpose  of  executing  any  documents
contemplated in Section 2.7(a), including any


                                                        52





registration statement or amendment thereto filed with the Commission, or making
any other governmental filing; and

         (b) The Administrative  Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments  either in the name of the Issuer Trust 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 this Trust Agreement.

         SECTION 8.20. Appointment of Administrative Trustees.

         (a) The  Administrative  Trustees  shall  initially  be Saul L.  Basch,
Roberta O'Brien and Robert C. Walker, and their successors shall be appointed by
the Holder of all the Common Securities.  The Administrative Trustees may resign
or be removed by the Holder of all the Common  Securities at any time.  Upon any
resignation or removal of an Administrative Trustee, the Depositor shall appoint
a successor  Administrative  Trustee.  If at any time there is no Administrative
Trustee,  the  Property  Trustee  or any  Holder  who has been a Holder of Trust
Securities  for at  least  six  months  may  petition  any  court  of  competent
jurisdiction for the appointment of one or more Administrative Trustees.

         (b) Whenever a vacancy in the number of  Administrative  Trustees shall
occur,  until such  vacancy is filled by the  appointment  of an  Administrative
Trustee in accordance  with this Section 8.20,  the  Administrative  Trustees in
office,  regardless of their number (and  notwithstanding any other provision of
this  Agreement),  shall  have  all the  powers  granted  to the  Administrative
Trustees and shall  discharge  all the duties  imposed  upon the  Administrative
Trustees by this Trust Agreement.

         (c)  Notwithstanding the foregoing or any other provision of this Trust
Agreement,  if any  Administrative  Trustee  who is a  natural  person  dies  or
becomes, in the opinion of the Holder of all the Common Securities,  incompetent
or incapacitated,  the vacancy created by such death, incompetence or incapacity
may be filled by the unanimous act of the remaining  Administrative Trustees, if
there were at least two of them prior to such vacancy, and by the Depositor,  if
there  were  not two  such  Administrative  Trustees  immediately  prior to such
vacancy  (with  the  successor  being a Person  who  satisfies  the  eligibility
requirement for Administrative Trustees set forth in Section 8.7).


                                   ARTICLE IX

                       DISSOLUTION, LIQUIDATION AND MERGER

         SECTION 9.1. Dissolution Upon Expiration Date.



                                                        53





         Unless earlier dissolved, the Issuer Trust shall automatically dissolve
on December 31, 2017 (the "Expiration Date"), and shall thereafter be terminated
by filing a Certificate of Cancellation with the Secretary of State of the State
of Delaware, following the distribution of the Trust Property in accordance with
Section 9.4.

         SECTION 9.2. Early Dissolution.

         The  first  to  occur  of any  of the  following  events  is an  "Early
Termination Event" upon the occurrence of which the Trust shall be dissolved:

         (a) the  occurrence  of a  Bankruptcy  Event  in  respect  of,  or the
dissolution or liquidation of, the Holder of all the Common Securities;

         (b) the written  direction to the  Property  Trustee from the Holder of
all the  Common  Securities  at any time to  dissolve  the  Issuer  Trust and to
distribute  the  Debentures  to Holders in exchange  for the Capital  Securities
(which  direction is optional and wholly within the  discretion of the Holder of
all the Common Securities);

         (c) the  redemption or  conversion of all of the Capital  Securities in
connection with the redemption or conversion of all the Debentures; and

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

         SECTION 9.3. Termination.

         The respective  obligations and responsibilities of the Issuer Trustees
and the Issuer  Trust  created and  continued  hereby shall  terminate  upon the
latest to occur of the following:  (a) the  distribution by the Property Trustee
to  Holders  of all  amounts  required  to be  distributed  hereunder  upon  the
liquidation  of the Issuer Trust pursuant to Section 9.4, or upon the redemption
of all of the Trust  Securities  pursuant to Section 4.2; (b) the payment of any
expenses owed by the Issuer 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 Issuer Trust or the Holders.

         SECTION 9.4. Liquidation.

         (a) If an Early  Termination  Event specified in clause (a), (b) or (d)
of Section 9.2 occurs or upon the  Expiration  Date,  the Issuer  Trust shall be
liquidated  by the Issuer  Trustees  as  expeditiously  as the  Issuer  Trustees
determine to be possible by distributing,  after  satisfaction of liabilities to
creditors  of the Issuer  Trust as provided by Section  3808(e) of the  Delaware
Business Trust Act and any other applicable law, to each Holder a Like Amount of
Debentures,  subject to Section 9.4(d).  Notice of liquidation 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


                                                        54





Liquidation  Date to each Holder of Trust  Securities at such  Holder's  address
appearing in the Securities Register. All such 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  9.4(d)  applies  receive  a  Liquidation
         Distribution,  as the Property Trustee and the Administrative  Trustees
         shall deem appropriate.

         (b) Except where Section 9.2(c) or 9.4(d)  applies,  in order to effect
the  liquidation  of the Issuer  Trust and  distribution  of the  Debentures  to
Holders, the Property Trustee, either itself acting as exchange agent or through
the appointment of a separate exchange agent,  shall establish a record date for
such distribution (which shall be not more than 45 days prior to the Liquidation
Date) and 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  9.2(c)  or  9.4(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 Trust
Securities  Certificates  to the exchange  agent for  exchange,  (iii) any Trust
Securities  Certificates  not so  surrendered  for  exchange  will be  deemed to
represent a Like Amount of Debentures  bearing accrued and unpaid interest in an
amount  equal  to  the  accumulated  and  unpaid  Distributions  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 (iv) all rights of Holders holding Trust Securities will cease,
except the right of such Holders to receive  Debentures  upon surrender of Trust
Securities Certificates.

         (d) If,  upon  dissolution  of the  Trust,  notwithstanding  the  other
provisions  of this Section  9.4,  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, or if an Early Termination Event specified in clause (c) of
Section 9.2 occurs,  the Trust  Property  shall be  liquidated  by the  Property
Trustee in such manner as the Property  Trustee  determines.  In such event,  in
connection with the winding-up of the Issuer Trust,  Holders will be entitled to
receive out of the assets of the Issuer  Trust  available  for  distribution  to
Holders,  after  satisfaction of liabilities to creditors of the Issuer Trust as
provided  by  Section  3808(e)  of the  Delaware  Business  Trust  Act and other
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


                                                        55





"Liquidation  Distribution").  If,  upon any such  winding  up, the  Liquidation
Distribution  can be paid only in part because the Issuer 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 Issuer Trust
on  the  Trust  Securities  shall  be  paid  on a pro  rata  basis  (based  upon
Liquidation  Amounts).  The Holder of all the Common Securities will be entitled
to  receive  Liquidation   Distributions  upon  any  such  winding-up  pro  rata
(determined as aforesaid) with Holders of Capital Securities,  except that, if a
Debenture  Event of  Default  specified  in  Section  5.1(1)  or  5.1(2)  of the
Indenture has occurred and is continuing,  the Capital  Securities  shall have a
priority over the Common Securities as provided in Section 4.4.

     SECTION 9.5.  Mergers,  Consolidations,  Amalgamations  or  Replacements of
Issuer Trust.

         The Issuer 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  9.5. The Issuer Trust may, at the request of the Holder of all
the Common Securities and, with the consent of the Administrative  Trustees, but
without the  consent of the Holders of the  Outstanding  Trust  Securities,  the
Property  Trustee or the  Delaware  Trustee,  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 Issuer Trust with respect to the Capital
Securities,  or (b)  substitutes  for the Capital  Securities  other  securities
having  substantially  the same terms as the Capital  Securities (the "Successor
Securities")  so long as the Successor  Securities have the same priority as the
Capital  Securities with respect to distributions and payments upon liquidation,
redemption and otherwise, (ii) a trustee of such successor entity possessing the
same  powers  and  duties  as the  Property  Trustee  is  appointed  to hold the
Debentures,  (iii)  such  merger,  consolidation,   amalgamation,   replacement,
conveyance,  transfer or lease does not cause the Capital Securities  (including
any  Successor  Securities)  to  be  downgraded  by  any  nationally  recognized
statistical  rating  organization  that then  assigns  a rating  to the  Capital
Securities,  (iv)  such  merger,   consolidation,   amalgamation,   replacement,
conveyance,  transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Capital Securities (including any Successor
Securities) in any material  respect,  (v) such  successor  entity has a purpose
substantially  identical to that of the Issuer Trust, (vi) prior to such merger,
consolidation,  amalgamation,  replacement,  conveyance,  transfer or lease, the
Issuer Trust has received an opinion from  independent  counsel  experienced  in
such  matters 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 Capital  Securities  (including
any  Successor  Securities)  in any material  respect,  and (b)  following  such
merger, consolidation, amalgamation, replacement, conveyance, transfer or lease,
neither the Issuer Trust nor such successor  entity will be required to register
as an  "investment  company"  under the  Investment  Company  Act, and (vii) the
Depositor  or its  permitted  successor  or  transferee  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 Agreement. Notwithstanding the foregoing, the Issuer Trust


                                                        56





shall not, except with the consent of holders of all of the Capital  Securities,
consolidate,  amalgamate,  merge  with or into,  or 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 Issuer  Trust or the  successor
entity to be  taxable as a  corporation  or  classified  as other than a grantor
trust for United States Federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1. Limitation of Rights of Holders.

         Except as set forth in Section 9.2, the death, incapacity, dissolution,
termination  or  bankruptcy  of any Person  having an  interest,  beneficial  or
otherwise, in Trust Securities shall not operate to annul, dissolve or terminate
this Trust Agreement, nor entitle the legal representatives, successors or heirs
of such Person or any Holder for such person,  to claim an accounting,  take any
action or 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.

         SECTION 10.2. Amendment.

         (a)  This  Trust  Agreement  may be  amended  from  time to time by the
Property  Trustee,  the  Administrative  Trustees  and the  Holder of the Common

provision herein that may be inconsistent with any other provision herein, or to
make any other  provisions  with respect to matters or questions  arising  under
this Trust Agreement,  which shall not be inconsistent with the other provisions
of this Trust Agreement,  or (ii) to modify,  eliminate or add to any provisions
of this Trust  Agreement to such extent as shall be necessary to ensure that the
Issuer Trust will not be taxable as a  corporation  or will be  classified  as a
grantor  trust for United States  Federal  income tax purposes at all times that
any Trust Securities are Outstanding or to ensure that the Issuer Trust will not
be required to register as an "investment  company" under the Investment Company
Act;  provided,  however,  that in either case (i) or (ii) such action shall not
adversely  affect in any material  respect the interests of the Delaware Trustee
or any Holder.

         (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust  Agreement  may be amended by the  Property  Trustee,  the  Administrative
Trustees  and the Holder of the Common  Securities,  without  the consent of the
Delaware Trustee,  and with (i) the consent of Holders of at least a Majority in
Liquidation  Amount of the Capital  Securities,  and (ii)  receipt by the Issuer
Trustees of an Opinion of Counsel to the effect that such amendment or the


                                                        57





exercise of any power  granted to the Issuer  Trustees in  accordance  with such
amendment  will not cause the Issuer Trust to be taxable as a corporation  or as
other than a grantor  trust for United  States  Federal  income tax  purposes or
affect the Issuer Trust's exemption from status as an "investment company" under
the Investment Company Act.

         (c) In  addition to and  notwithstanding  any other  provision  in this
Trust  Agreement,  without  the  consent  of each  affected  Holder,  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 Holder to institute suit for the
enforcement of any such payment on or after such date; and  notwithstanding  any
other  provision  herein,  without the  unanimous  consent of the Holders,  this
paragraph (c) of this Section 10.2 may not be amended.

         (d)  Notwithstanding  any other provisions of this Trust Agreement,  no
Issuer  Trustee  shall  enter  into or consent  to any  amendment  to this Trust
Agreement  that would cause the Issuer Trust to fail or cease to qualify for the
exemption  from status as an "investment  company" under the Investment  Company
Act or to be  taxable  as a  corporation  or to be  classified  as other  than a
grantor trust for United States Federal income tax purposes.

         (e)  Notwithstanding  anything in this Trust Agreement to the contrary,
(i) without the consent of the Depositor and the Administrative  Trustees,  this
Trust  Agreement  may not be amended in a manner  that  imposes  any  additional
obligation on the Depositor or the Administrative Trustees, and (ii) without the
consent of the Delaware  Trustee,  this Trust  Agreement may not be amended in a
manner that imposes any additional obligation on the Delaware Trustee.

         (f) In the event that any  amendment  to this Trust  Agreement is made,
the  Administrative  Trustees or the Property  Trustee shall promptly provide to
the Depositor a copy of such amendment.

         (g) Neither the  Property  Trustee nor the  Delaware  Trustee  shall be
required to enter into any  amendment to this Trust  Agreement  that affects its
own  rights,  duties or  immunities  under this Trust  Agreement.  The  Property
Trustee  shall be  entitled  to receive an Opinion of Counsel  and an  Officers'
Certificate  stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

         SECTION 10.3. Separability.

         In  case  any  provision  in  this  Trust  Agreement  or in  the  Trust
Securities  Certificates  shall  be  invalid,  illegal  or  unenforceable,   the
validity,  legality and enforceability of the remaining  provisions shall not in
any way be affected or impaired thereby.

         SECTION 10.4. Governing Law.

         THIS TRUST  AGREEMENT  AND THE RIGHTS  AND  OBLIGATIONS  OF EACH OF THE
HOLDERS, THE ISSUER TRUST, THE DEPOSITOR AND THE ISSUER TRUSTEES WITH RESPECT TO

WITH AND GOVERNED BY THE LAWS OF THE STATE OF DELAWARE WITHOUT  REFERENCE TO ITS
CONFLICT OF LAW  PROVISIONS.  THE  PROVISIONS OF SECTION 3540 OF TITLE 12 OF THE
DELAWARE CODE SHALL NOT APPLY TO THIS TRUST.

         To the fullest  extent  permitted by Delaware  law,  there shall not be
applicable to the Issuer Trust,  the Issuer Trustees or this Trust Agreement any
provisions  of law  (whether  statutory  or  common)  of the  State of  Delaware
pertaining to trusts (other than the Delaware Business Trust Act) that relate to
or regulate in a manner  inconsistent  with the terms hereof (a) the filing with
any court or  governmental  body or agent of trustee  accounts or  schedules  of
trustee  fees and  charges,  (b)  affirmative  requirements  to post  bonds  for
trustees, officers, agents or employees of a trust, (c) the acquisition, holding

         SECTION 10.5. Payments Due on Non-Business Day.

         If the date fixed for any payment on any Trust  Security shall be a day

may be made on the  next  succeeding  day  that is a  Business  Day  (except  as
otherwise  provided  in  Sections  4.1(a) and  4.2(d)),  with the same force and
effect as though made on the date fixed for such payment,  and no  Distributions
shall accumulate on such unpaid amount for the period after such date.

         SECTION 10.9. Agreement Not to Petition.

         Each of the Issuer  Trustees and the Depositor agree for the benefit of
the Holders that, until at least one year and one day after the Issuer Trust has
been  terminated in accordance  with Article IX, they shall not file, or join in
the  filing of, a  petition  against  the  Issuer  Trust  under any  bankruptcy,
insolvency,  reorganization  or other similar law  (including  the United States
Bankruptcy  Code)  (collectively,  "Bankruptcy  Laws") or otherwise  join in the
commencement  of any  proceeding  against the Issuer Trust under any  Bankruptcy
Law. The Property  Trustee and the Depositor  agree, for the benefit of Holders,
that if the  Depositor or any Issuer  Trustee  takes action in violation of this
Section  10.9,  then at the expense of the  Depositor,  the Property  Trustee or
Depositor, as the case may be, shall file an answer with the bankruptcy court or
otherwise  properly contest the filing of such petition by the Depositor against
the Issuer Trust or the  commencement  of such action and raise the defense that
the  Depositor  has  agreed in  writing  not to take such  action  and should be
estopped and precluded therefrom and such other defenses, if any, as counsel for
the Issuer Trustees or the Issuer Trust may assert.

         SECTION 10.10. Trust Indenture Act; Conflict with Trust Indenture Act.

         (a) This Trust  Agreement  is subject  to the  provisions  of the Trust

pursuant to the terms herein and shall, to the extent applicable, be governed by
such provisions.

         (b) The Property  Trustee  shall be the only Issuer  Trustee which is a
trustee for the purposes of the Trust Indenture Act.

         (c) If any provision hereof limits, qualifies or conflicts with another
provision  hereof  which is  required  or deemed to be  included  in this  Trust
Agreement by any of the provisions of the Trust  Indenture Act, such required or
deemed  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.

     SECTION 10.11. Acceptance of Terms of Trust Agreement,  Guarantee Agreement

OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT, THE GUARANTEE AGREEMENT
AND THE INDENTURE, AND AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS
OF THE GUARANTEE AGREEMENT AND THE INDENTURE, AND SHALL CONSTITUTE THE AGREEMENT

SUCH  HOLDER  AND SUCH  OTHERS  THAT THE  TERMS  AND  PROVISIONS  OF THIS  TRUST
AGREEMENT SHALL BE BINDING,  OPERATIVE AND EFFECTIVE AS BETWEEN THE ISSUER TRUST
AND SUCH HOLDER AND SUCH OTHERS.

         This Trust  Agreement  may be executed  in any number of  counterparts,
