                      FORWARD LOOKING INFORMATION

         Certain matters discussed in this 10-Q are "forward-looking statements"
intended to qualify  for the safe  harbors  from  liability  established  by the
Private  Securities   Litigation  Reform  Act  of  1995.  These  forward-looking
statements  can  generally  be  identified  as such  because  the context of the
statement  will  include  words such as the Company  "believes,"  "anticipates,"
"expects" or words of similar  import.  Similarly,  statements that describe the
Company's future plans, objectives or goals are also forward-looking statements.
Such  statements  address  future  events  and  conditions   concerning  capital
expenditures,  earnings,  litigation,  rate and other  regulatory  matters,  the
pending Merger,  liquidity and capital resources, and accounting matters. Actual
results in each case could differ materially from those currently anticipated in
such statements,  by reason of factors such as electric  utility  restructuring,
including the ongoing state and federal activities;  future economic conditions;
developments in the legislative, regulatory and competitive markets in which the
Company operates;  and other circumstances  affecting  anticipated  revenues and
costs.

SOUTHWESTERN PUBLIC SERVICE COMPANY
Notes to Condensed Consolidated Financial Statements
(Unaudited)


(1) Interim  periods.  The results of operations for the interim periods are not
necessarily an indication of the expected results for the fiscal year due to the
seasonal nature of Southwestern Public Service Company's (the Company) business.
The unaudited condensed  consolidated  financial statements included herein were
prepared from the books of the Company in  accordance  with  generally  accepted
accounting  principles and reflect all adjustments (none of which are other than
normal recurring adjustments) which are, in the opinion of management, necessary
to provide a fair statement of the results of operations and financial  position
for the interim  periods.  Such financial  statements  generally  conform to the
presentation  reflected in the  Company's  Annual  Report to  Stockholders.  The
current interim period reported herein is included in the fiscal year subject to
independent audit at the end of the year.


(2) Income taxes. The components of income tax expense (benefit) are as follows:

</TABLE>

(3) Merger  with Public  Service  Company of  Colorado  (PSCo).  The Company and
Denver-based  PSCo entered into a definitive  merger  agreement  (the Merger) on
August 22, 1995, to form a registered  public utility  holding company named New
Century  Energies,  Inc.,  which will be the parent  company for the Company and
PSCo. The transaction is subject to various conditions, including receipt of the
approval  of or the  taking  of other  action  by the  Securities  and  Exchange
Commission, the Federal Trade Commission, the Department of Justice, the Nuclear
Regulatory Commission,  the Federal Energy Regulatory Commission (FERC), and the
state public utility commissions in Texas,  Colorado,  New Mexico,  Wyoming, and
Kansas.  (See GENERAL.  Merger  Agreement in the Company's 1996 Annual Report on
Form 10-K.)

         The Merger,  with a targeted  completion date in the spring of 1997, is
conditioned on qualifying as a tax-free  reorganization  and being accounted for
as a pooling of interests.

(4)  Issuance  of  securities.  The  Company  redeemed in  September  1996,  the
$25,000,000  6-1/2%  pollution  control  revenue  bonds (PCRBs) due 2004 and the
$32,300,000  6-5/8% PCRBs due 2009 and replaced these series in September  1996,
with $57,300,000 5-3/4% PCRBs due 2016.

         In October 1996, the Company called its $25,000,000 principal amount of
13-1/2% PCRBs and issued  $25,000,000 of new variable rate PCRBs.  In connection
with the new issuance of variable  rate PCRBs,  the Company has an interest rate
swap  agreement,  which,  in effect,  fixes the interest  rate on a  $25,000,000
notional  amount at 6.435%.  Amounts paid or received  under this  agreement are
accrued  as  interest  rates  change  and are  recognized  over  the life of the
agreement  as an  adjustment  to  interest  expense.  The  Company is exposed to
interest rate risk in the event of nonperformance by the counterparty;  however,
the Company does not anticipate such nonperformance.

         In October 1996,  Southwestern Public Service Capital I, a wholly owned
trust,  issued in a public  offering  $100,000,000 of its 7.85% Trust  Preferred
Securities,  Series  A. The sole  asset of the trust is $103,000,000  principal
amount of the  Company's  7.85%  Deferrable  Interest  Subordinated  Debentures,
Series A due  September  1,  2036.  The funds from this  financing  were used to
reduce short-term debt.

(5) Rate and  regulatory  matters.  The Company may effect  changes in its rates
only as approved by the  regulatory  authorities  governing  its  jurisdictions.
Amounts   ultimately   realized  will  differ  from  amounts   approved  because
kilowatt-hour  sales  and  other  factors  will  vary  from  those  used in rate
proceedings.

         A Public Utility  Commission of Texas (PUCT)  substantive rule requires
periodic  examination  of the  Company's  fuel and  purchased  power costs,  the
efficiency of the use of such fuel and purchased  power,  fuel  acquisition  and
management policies and purchase power commitments.  On May 1, 1995, the Company
filed  with the PUCT a  petition  for a fuel  reconciliation  for the  months of
January 1992 through December 1994. A hearing was held in September 1995, and in
January  1996 an order was  issued  which  required  the  Company to make a $3.9
million fuel refund  consisting of $2.1 million of overrecovered  fuel costs and
$1.8 million of  disallowed  fuel costs for the period.  This refund was made in
April 1996.  Additionally,  the order  required  the Company to flow  through to
customers  100% of margins  from  non-firm  off-system  opportunity  sales as of
January 1995.  Prior PUCT rulings had allowed the Company to retain 25% of these
margins.  The 100% flow  through is required by PUCT rules,  absent rule waiver.
The Company filed a motion for rehearing on January 25, 1996. The PUCT issued an
order on March 14 denying rehearing on the fuel disallowance (which was adjusted
to $1.9 million),  and ordered the flow through of 100% of the margin  effective
with the first billing cycle after the date of the order.  On May 24, 1996,  the
Company  filed an appeal  in the  Travis  County  District  Court on the  PUCT's
decision with respect to the $1.9 million of disallowed  fuel costs in which the
hearing of merits was held on November 1, 1996.  The  District  Court upheld the
PUCT's  decision  on the  disallowed  fuel  costs.  It is  anticipated  that the
District  Court  decision  will be appealed  to the Texas Court of Appeals.  The
ultimate  outcome of this  matter  will not  significantly  affect  consolidated
financial  results.  Currently  the  Company  has  approximately  $11 million in
underrecovered  fuel  costs and has filed with the PUCT for a change in the fuel
factors. Settlement was made with the PUCT and intervening parties, and the fuel
factors were interimly approved and are now in effect.

         On December 19,  1989,  the FERC issued its final order  regarding  the
1985 rate case. The Company  appealed certain portions of the order that related
to recognition in rates of the reduction of the federal income tax rate from 46%
to 34%. The United States Court of Appeals for the District of Columbia  Circuit
remanded the case,  directing the FERC to reconsider  the Company's  claim of an
offsetting  cost and limiting the FERC's  actions.  The FERC issued its Order on
Remand in July 1992,  required  filings were made and a hearing was completed in
February 1994. In October 1994, the  administrative law judge issued a favorable
initial  decision  that, if approved by the FERC,  would result in a substantial
recovery by the  Company.  Negotiated  settlements  with the  Company's  partial
requirements  customers  and TNP  were  approved  by the  FERC in July  1993 and
September 1993, respectively, and the Company received approximately $2,800,000,
including  interest.  In a settlement with the Company's New Mexico  cooperative
customers the Company received approximately $7,000,000, including interest. The
FERC approved this  settlement in July 1995.  Resolutions  of these matters with
the  remaining  wholesale  customers,  Golden  Spread  member  cooperatives  and
Lyntegar  Electric  Cooperative,  have  not been  reached.  The  Company  cannot
reasonably  estimate the remaining amount  recoverable  from these  proceedings;
however, a favorable resolution could materially improve  consolidated  earnings
in the year in which it is resolved.

(6) Other events.  As discussed in the Company's 1996 Annual Report on Form 10-K
under  BUSINESS.  Nonutility  Businesses,  Quixx  Corporation,  a  wholly  owned
subsidiary  of the  Company,  holds a 49%  limited  partnership  interest in BCH
Energy Limited  Partnership which owns a waste-to-energy  cogeneration  facility
located near Fayetteville,  North Carolina.  Limited commercial operation of the
BCH project  began in June 1996;  however,  the  facility  has not  achieved the
expected performance level. Quixx is currently negotiating with the project debt
and equity holders  concerning the  restructuring  of the project to achieve the
required improvements on economically viable terms. Should it not be possible to
economically complete the necessary improvements, Quixx may be required to write
off a portion or all of its  investment  of  approximately  $15,000,000 in this
project.  The  resolution  of this matter could  adversely  affect  consolidated
earnings for the year.

         The banks  providing  the debt  financing to the project have  withheld
funds for the BCH project and for the  construction  of the  companion  Carolina
project discussed in such Form 10-K and construction of the Carolina project has
been suspended.  Quixx is also in  negotiations  concerning the viability of the
Carolina project and the restoration of the funding for its construction.

     The Company was named as a defendant in a case entitled  Thunder Basin Coal
Co. v.  Southwestern  Public Service Co., No. 93-CV-304B (D. Wyo.). (See ITEM 3.
LEGAL PROCEEDINGS in the Company's 1996 Annual Report on Form 10-K.) On November
1, 1994,  the jury returned a verdict in favor of Thunder Basin and awarded them
damages of  approximately  $18,800,000.  The Company appealed the judgement to
the Tenth Circuit  Court of Appeals and on January 7, 1997,  that Court found in
favor of Thunder  Basin and upheld the $18,800,000  judgement.  The Company is
considering a motion for rehearing.

         Management   believes  that  the  payment  would  be  recoverable  from
ratepayers,  although any such recovery  would be subject to regulatory  review.
Therefore,  management  believes  that the ultimate  resolution  will not have a
material adverse effect on the Company's consolidated financial statements.

(7) General.  See note (1) of Notes to Consolidated  Financial Statements in the
Company's  1996  Annual  Report  on Form  10-K for a  summary  of the  Company's
significant accounting policies.

Independent Accountant's Report


Southwestern Public Service Company:

We have  reviewed  the  accompanying  condensed  consolidated  balance  sheet of
Southwestern  Public Service  Company and  subsidiaries as of November 30, 1996,
and the related condensed consolidated statements of earnings and cash flows for
the three-month and twelve-month periods ended November 30, 1996 and 1995. These
financial statements are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute  of  Certified  Public  Accountants.  A review  of  interim  financial
information consists principally of applying analytical  procedures to financial
data and making  inquiries of persons  responsible  for financial and accounting
matters.  It is  substantially  less in scope than an audit in  accordance  with
generally accepted auditing standards,  the objective of which is the expression
of an opinion regarding the financial statements taken as a whole.  Accordingly,
we do not express such an opinion.

Based on our review, we are not aware of any material  modifications that should
be made to such condensed  consolidated  financial  statements for them to be in
conformity with generally accepted accounting principles.

We have  previously  audited,  in accordance  with generally  accepted  auditing
standards,  the consolidated  balance sheet and statement of  capitalization  of
Southwestern  Public Service Company and subsidiaries as of August 31, 1996, and
the related consolidated  statements of earnings,  common shareholders'  equity,
and cash flows for the year then ended (not presented herein); and in our report
dated  October  10,  1996,  we  expressed  an   unqualified   opinion  on  those
consolidated financial statements.  In our opinion, the information set forth in
the accompanying  condensed consolidated balance sheet as of August 31, 1996, is
fairly stated, in all material respects, in relation to the consolidated balance
sheet from which it has been derived.

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

         Operating Revenues and Kilowatt-Hour Sales

         Substantially all of the Company's  operating  revenues result from the
sale of electric  energy.  The principal  factors  determining  revenues are the
amount and price per unit of energy sold.  The  following  table  describes  the
principal components of changes in revenues.

Increase (decrease) in non-firm kwh sales (in millions)        132             (45)

* Comprised of retail and wholesale excluding economy and interruptible (non-firm) wholesale kwh sales.
</TABLE>

         Variations in Kwh Sales.  The revenue  increases  for the  twelve-month
period  was due  primarily  to  increased  Kwh  sales to all  retail  (ultimate)
customers and to rural  electric  cooperatives  (RECs) due primarily to a hotter
than  normal  late  spring and early  summer.  These  conditions  increased  air
conditioning load for the twelve-month period. Contributing to the increase were
kwh sales  resulting from the  acquisition  of electric  properties in the Texas
Panhandle  from  Texas-New  Mexico  Power  Company  (TNP).  The decrease for the
quarter  is  primarily  due to a  significant  decline  in  firm  sales  to firm
municipal customers including the Texas cities of Lubbock, Brownfield, Tulia and
Floydada.  These customers  purchased  available non-firm power from the Company
and others.  Although kwh sales increased modestly in the quarter, the migration
of these customer  purchases to the lower priced non-firm power caused a decline
in revenues that was not offset by the increased level of sales.

         Variations in Rates.  Increased revenues for the three-month period are
due  primarily  to  increased  demand  charges  per kwh  received  from  certain
wholesale customers. The decreases for the twelve-month period are primarily the
result  of  last  year's  settlement  of  the  1985  Federal  Energy  Regulatory
Commission  (FERC)  rate  case  with the  Company's  New  Mexico  wholesale  REC
customers. This settlement contributed  increased revenues of approximately $4.0
million  (and  interest  of $3.0  million  that is  included  in other  income).
Interruptible  rates  available  to  certain  classes of retail  customers  were
approved  and  implemented  in Texas and New Mexico in 1996 which acted to lower
related  revenues  for both  periods.  The Company  sought  approval to put into
effect these new rates in compliance with settlement  agreements in the 1993 and
1994  rate  cases in Texas  and New  Mexico,  respectively,  and to  respond  to
generation resource capacity needs.

     Variations in Fuel and Purchased Power Cost Recovery. Revenue increases for
the three- and twelve-month periods are due to increased gas and coal costs.

         Variations in Non-Firm Kwh Sales.  The amount of revenues  arising from
non-firm  sales is dependent,  in large part,  upon the amount and cost of power
available to the Company for sale,  the demand for power,  the  availability  of
competing  hydroelectric  power from the  Northwest  and  generation  from major
plants in the West.  The increases for the three- and  twelve-month  periods are
due  primarily  to increased  fuel  charges  included in the non-firm kwh sales.
Additionally,  interruptible  sales to  Public  Service  Company  of New  Mexico
increased for both periods because of an increased demand for power.

         Operating Expenses and Non-Operating Items

         Operating  Expenses.  Fuel and purchased power expense  comprised 57.7%
and 58.9% of total  operating  expenses  for the three and twelve  months  ended
November 30, 1996, respectively. When compared to the corresponding periods last
year, these expenses  increased $12.9 million,  or 14.2%, and $66.8 million,  or
17.5%,  for the three- and  twelve-month  periods  respectively.  Increased fuel
costs,  primarily  gas costs,  caused  increases in both  periods.  Fuel expense
(excluding purchased power expense), per net kwh generated,  increased from 1.83
to 2.01  cents  and  from  1.78 to 2.02  cents  for the  respective  three-  and
twelve-month periods due to higher natural gas and coal costs.

         Total operating expenses, excluding fuel and purchased power, increased
$1.2 million,  or 1.7%, for the three-month  period, and increased $6.6 million,
or 2.1%, for the twelve-month period. The increase in the three-month period was
due primarily to steam production maintenance expenses.  Additionally, a decline
in taxable  income  lowered  taxes in the current  period.  The  increase in the
twelve-month period was due primarily to increased steam production  maintenance
expense  and  expenses  associated  with  the  acquisition  of the TNP  electric
properties.  Maintenance  expenses  were  higher  due  to the  normal  recurring
eighteen-month repair cycle and additional cooling tower maintenance costs.

         Other Income.  Other income  increased for the  three-month  period due
primarily to reduced taxes and merger and business  integration expenses as well
as slightly increased subsidiary earnings.  Other income during the twelve-month
period was favorably  impacted by the approximate $7.7 million after-tax gain on
the sale of certain  water rights by Quixx  Corporation.  The gain was offset by
increased  merger  and  business  integration  expenses  of  approximately  $5.4
million.  The Company  reclassified  these expenses from  operating  expenses to
other income to conform with a FERC order.  Other income was favorably  impacted
in the prior  twelve-month  period by the  approximate  $3.0 million of interest
arising from the rate case settlement with New Mexico wholesale customers.

         Earnings

         Current  earnings  applicable to common stock declined for both periods
in part because of increased  interest  expense due to increased  long-term  and
short-term  debt.  These higher levels of debt were caused by the  retirement of
preferred  stock,  the 1995  acquisition  of  electric  properties  from TNP and
increased  construction  expenditures.  Twelve-month  earnings  were  positively
affected by the sale of a portion of underground water rights held by Quixx that
added 19 cents per share.  However,  these earnings were  adversely  affected by
merger-related and business integration expenses. Additionally, earnings for the
prior twelve-month period had been boosted by the rate settlement with wholesale
customers  in New Mexico  that added 11 cents per share,  and by a change in the
estimate  of  delivered-but-not-billed  kwh sales that added 13 cents per share.
These  estimated  kwh sales  relate to energy used by  customers  but not billed
until the subsequent month. Operating income was flat in the three-month  period
and  decreased  in the  twelve-month  period  primarily  because of the  greater
maintenance expenses and the expenses associated with the TNP acquisition.

         Assuming normal weather  conditions,  1997 operating income is expected
to remain relatively flat, but net earnings for 1997 will be negatively impacted
by increased  merger-related and business  integration  expenses.  Any write-off
associated  with the BCH project  discussed in Note (6) would further  adversely
affect  such  earnings.  A  resolution  of the 1985 FERC  rate  case with  Texas
wholesale REC  customers,  by settlement or otherwise,  would  favorably  affect
income and earnings in the year received.

LIQUIDITY AND CAPITAL RESOURCES

         The   Company's   demand  for  capital  is  normally   related  to  the
construction  of utility plant and  equipment.  Cash  construction  expenditures
excluding  AFUDC for the three and twelve months ended  November 30, 1996,  were
$54.5 million and $133.5 million, respectively. Also in fiscal 1996, the Company
received  regulatory  approval to make investments in Quixx of up to $15 million
each year  beginning  in fiscal  1996 and  continuing  for five  years.  Quixx's
investment in independent  power projects is dependent upon suitable  investment
opportunities  and the  availability of capital.  The Company cannot  accurately
forecast  the  portion  of  internally  generated  funds to be used for  capital
expenditures,  but expects that it will be approximately  40% in fiscal 1997. To
the extent the capital required in 1997 is not supplied by internally  generated
funds,  the Company expects to obtain such capital from short-term  borrowing or
from the sale of long-term  debt,  preferred  stock  and/or  common  stock.  The
Company's   estimates  of  capital  needs,   in  particular   those  related  to
construction  and the  generation  of  internal  funds are subject to review and
revision,  and may vary  substantially  from the foregoing  especially in a more
competitive  environment.  Due to the merger, Standard & Poor's is reviewing the
Company's rated debt for possible downgrade.

         In August  1994 the  Company  entered in a forward  interest  rate swap
agreement in  anticipation  of  redeeming  its $25 million  principal  amount of
13-1/2%  Pollution Control Revenue Bonds (PCRBs) with a new issuance of variable
rate  PCRBs.  Such bonds were  redeemed  October 1, 1996,  and  replaced  with a
variable  rate bond issue that has been  swapped  for a fixed rate of 6.435% due
July 1, 2016. Additionally,  the Company redeemed on September 26, 1996, the $25
million  6-1/2% PCRBs due 2004 and the $32.3  million  6-5/8% PCRBs and replaced
these  series on  September  18,  1996,  with  $57.3  million  5-3/4%  PCRBs due
September 1, 2016.

         In October 1996,  Southwestern Public Service Capital I, a wholly owned
trust,  issued  in a public  offering  $100  million  of 7.85%  Trust  Preferred
Securities,  Series  A. The sole  asset of the trust is $103  million  principal
amount of the  Company's  7.85%  Deferrable  Interest  Subordinated  Debentures,
Series A due  September  1,  2036.  The  securities  are shown as SPS  Obligated
Mandatorily  Redeemable  Preferred Securities of Subsidiary Trust holding solely
Subordinated Debentures of SPS on the Consolidated Balance Sheet. The funds from
this financing were used to reduce short-term debt.

         The Company also has  effective a shelf  registration  under which $220
million of debt securities and/or preferred stock are available for issuance.

 OTHER MATTERS

         Electric  utilities have  historically  operated in a highly  regulated
environment  in which they have an  obligation  to provide  electric  service to
their  customers  in return for an  exclusive  franchise  within  their  service
territory  with  an  opportunity  to  earn a  regulated  rate  of  return.  This
regulatory  environment  is  changing.  The  generation  sector has  experienced
competition from nonutility power producers and the FERC is requiring utilities,
including the Company, to provide wholesale  transmission  service to others and
may order electric utilities to enlarge their transmission systems to facilitate
transmission  services  without  impairing  reliability.  On July 9,  1996,  the
Company filed its open access  transmission tariff in compliance with FERC Order
No. 888. (See GENERAL.  Competition  in the Company's 1996 Annual Report on Form
10-K.)  State  regulatory  authorities  are in the process of  changing  utility
regulations  in  response to federal and state  statutory  changes and  evolving
markets.  All  of the  Company's  jurisdictions  continue  to  evaluate  utility
regulations  with respect to competition,  and  legislative  proposals to effect
retail  wheeling are expected to be introduced in 1997. The Company is unable to
predict what financial  impact or effect the adoption of these  proposals  would
have on its  operations.  In part in response to these  changing  conditions the
Company has entered  into a  definitive  merger  agreement  with Public  Service
Company  of  Colorado  (the  Merger).  Consummation  of the Merger is subject to
customary conditions including receiving regulatory authority approvals. The two
utilities  are working  toward a completion  date in spring 1997.  The foregoing
discussions of the Company's  "Results of Operations" and "Liquidity and Capital
Resources"  do not take into account any changes that could arise as a result of
the Merger.

Indenture to be given 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 their agent duly appointed in writing; and, except as herein
otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where it is hereby
expressly required, to the Company. 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 Indenture and (subject to Section 601)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

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

            (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders entitled to give or take any request, demand, authorization, direction,
notice, consent, waiver or other action, or to vote on any action, authorized or
permitted to be given or taken by Holders. If not set by the Company prior to
the first solicitation of a Holder made by any Person in respect of any such
action, or, in the case of any such vote, prior to such vote, the record date
for any such action or vote shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 701)
prior to such first solicitation or vote, as the case may be. With regard to any
record date, only the Holders on such date (or their duly designated proxies)
shall be entitled to give or take, or vote on, the relevant action.

                                   -13-



            (d)   The ownership of Securities shall be proved by
the Securities Register.

            (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every 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 Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

SECTION 105.  Notices, Etc. to Trustee and the Company.

            Any request, demand, authorization, direction, notice, consent,
waiver or Act or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

            (1)  the Trustee by any Holder or by the Company
      shall be sufficient for every purpose hereunder if made,
      given, furnished or filed in writing to or with the
      Trustee at its Corporate Trust Office, Attention:
      Corporate Trust Administration, or

            (2) the Company by the Trustee or by any Holder shall be sufficient
      for every purpose hereunder (unless otherwise herein expressly provided)
      if in writing and mailed, first-class postage prepaid, to the Company
      addressed to it at the address of its principal office specified in the
      first paragraph of this Indenture, Attention: Secretary, or at any other
      address previously furnished in writing to the Trustee by the Company.

SECTION 106.  Notice to Holders; Waiver.

            Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at such Holder's address as it appears in the Securities
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in a notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other





<PAGE>


                                   -14-



Holders. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

            In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

            If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

SECTION 108.  Effect of Headings and Table of Contents.

            The Article and Section headings herein and the Table of Contents
are for convenience only and shall not affect the construction hereof.

SECTION 109.  Successors and Assigns.

            The Company will have the right at all times to assign any of its
rights or obligations under this Indenture to (a) a direct or indirect wholly
owned Subsidiary, provided that, in the event of any such assignment, the
Company will remain liable for all such obligations and (b) to any other Person
in accordance with the provisions of Article Eight of this Indenture. This
Indenture may not otherwise be assigned by the parties hereto. Subject to the
foregoing, this Indenture is binding upon and inures to the benefit of the
parties hereto and their respective successors and assigns.

SECTION 110.  Separability Clause.

            In case any provision in this Indenture or in the Securities 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 111.  Benefits of Indenture.

            Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness, the holders of Preferred
Securities (to the extent provided herein) and the Holders of Securities, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

SECTION 112.  GOVERNING LAW.

            THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.

SECTION 113.  Legal Holidays.

            In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest on or principal of the Securities shall be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay) except that, if such Business Day is in
the next succeeding calendar year, such payment of interest on or principal of
the Securities, as the case may be, shall be made on the immediately preceding
Business Day, in each case, with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity.

      Section 901(5)).

            All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set

<PAGE>


                                   -21-



delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

            The Securities shall be subordinated in right of payment to Senior
Indebtedness as provided in Article Eleven.

SECTION 302.  Denominations.

            The Securities of each series shall be issuable only in registered
form, without coupons, and only in denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $25 and any integral multiple thereof.

SECTION 303.  Execution, Authentication, Delivery and Dating.

            The Securities shall be executed on behalf of the Company by its
Chairman, its President or one of its Vice Presidents, under its corporate seal
reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.

            Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities.

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities; and the Trustee in
accordance with such Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,







<PAGE>


                                   -22-



            (1) if the form of such Securities has been established by or
      pursuant to Board Resolutions as permitted by Section 201, that such form
      has been established in conformity with the provisions of this Indenture;

            (2) if the terms of such Securities have been established by or
      pursuant to Board Resolutions as permitted by Section 301, that such terms
      have been established in conformity with the provisions of this Indenture;
      and

            (3) that such Securities, when authenticated and delivered by the
      Trustee and issued by the Company in the manner and subject to any
      conditions specified in such Opinion of Counsel, will constitute valid and
      legally binding obligations of the Company enforceable in accordance with
      their terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting creditors' rights and to general equity
      principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities or this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee.

            Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
authentication of each Security of such series if such documents are delivered
at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

            Each Security shall be dated the date of its authentication.







<PAGE>


                                   -23-



            No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

SECTION 304.  Temporary Securities.

            Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

            If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at any office or agency of the Company designated pursuant to Section
1002, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of any authorized
denominations. Until so exchanged the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

SECTION 305.  Registration, Registration of Transfer and
                Exchange.

            The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant Section 1002 being herein sometimes
collectively referred to as the "Securities Register") in which, subject to





<PAGE>


                                   -24-



such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Securities Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.

            Upon surrender for registration of transfer of any Security of a
series at an office or agency of the Company designated pursuant to Section 1002
for such purpose for that series, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of the same series of any authorized
denominations and of a like aggregate principal amount.

            At the option of the Holder, Securities of any series may be
exchanged for other Securities of the same series of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

            All Securities issued upon any registration of transfer or exchange
of Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

            Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities Registrar duly executed, by the
Holder thereof or such Holder's attorney duly authorized in writing.

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1207 not involving any transfer.






<PAGE>


                                   -25-



            If the Securities of any series (or of any series and specified
tenor) are to be redeemed in part, the Company will not be required to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities that may be selected for redemption and ending
at the close of business on the day of such mailing.

            The provisions of clauses (1), (2), (3) and (4) below shall apply
only to Global Securities:

            (1) Each Global Security authenticated under this Indenture shall be
      registered in the name of the Depositary designated for such Global
      Security or a nominee thereof and delivered to such Depositary or a
      nominee thereof or custodian therefor, and each such Global Security shall
      constitute a single Security for all purposes of this Indenture.

            (2) Notwithstanding any other provision in this Indenture, no Global
      Security may be exchanged in whole or in part for Securities registered,
      and no transfer of a Global Security in whole or in part may be
      registered, in the name of any Person other than the Depositary for such
      Global Security or a nominee thereof unless (A) such Depositary (i) has
      notified the Company that it is unwilling or unable to continue as
      Depositary for such Global Security or (ii) has ceased to be a clearing
      agency registered under the Exchange Act at a time when the Depositary is
      required to be so registered to act as such Depositary, (B) there shall
      have occurred and be continuing an Event of Default with respect to such
      Global Security, (C) the Company in its sole discretion determines that
      such Global Security shall be so exchangeable, or (D) there shall exist
      such circumstances, if any, in addition to or in lieu of the foregoing as
      have been specified for this purpose as contemplated by Section 301.

            (3)   Subject to clause (2) above, any
      exchange of a Global Security for other Securities
      may be made in whole or in part, and all





<PAGE>


                                   -26-



      Securities issued in exchange for a Global Security or any portion thereof
      shall be registered in such names as the Depositary for such Global
      Security shall direct.

            (4) Every Security authenticated and delivered upon registration of
      transfer of, or in exchange for or in lieu of, a Global Security or any
      portion thereof, whether pursuant to this Section, Section 304, 306, 906
      or 1207 or otherwise, shall be authenticated and delivered in the form of,
      and shall be, a Global Security, unless such Security is registered in the
      name of a Person other than the Depositary for such Global Security or a
      nominee thereof.

SECTION 306.  Mutilated, Destroyed, Lost and Stolen
                Securities.

            If any mutilated Security is surrendered to the Trustee, the Company
shall execute, and the Trustee shall authenticate and deliver in exchange
therefor, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

            If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute, and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

            In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

            Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses






<PAGE>


                                   -27-



(including the fees and expenses of the Trustee) connected
therewith.

            Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

            The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest Rights Preserved.

            Except as otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

            Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

            (1) the Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security of such series and the date of the proposed payment, and
      at the same time the





<PAGE>


                                   -28-



      Company shall deposit with the Trustee an amount of money equal to the
      aggregate amount proposed to be paid in respect of such Defaulted Interest
      or shall make arrangements satisfactory to the Trustee for such deposit
      prior to the date of the proposed payment, such money when deposited to be
      held in trust for the benefit of the Persons entitled to such Defaulted
      Interest as in this clause provided. Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest which shall
      be not more than 15 days and not less than 10 days prior to the date of
      the proposed payment and not less than 10 days after the receipt by the
      Trustee of the notice of the proposed payment. The Trustee shall promptly
      notify the Company of such Special Record Date and, in the name and at the
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to each Holder of Securities of such series
      at such Holder's address as it appears in the Securities Register, not
      less than 10 days prior to such Special Record Date. Notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor having been so mailed, such Defaulted Interest shall be paid to
      the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on such Special Record Date and shall no longer be payable pursuant to the
      following clause (2).

            (2) The Company may make payment of any Defaulted Interest on the
      Securities of any series in any other lawful manner not inconsistent with
      the requirements of any securities exchange on which the Securities may be
      listed, and, if so listed, upon such notice as may be required by such
      exchange, if, after notice given by the Company to the Trustee of the
      proposed payment pursuant to this clause, such manner of payment shall be
      deemed practicable by the Trustee.

            Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration





<PAGE>


                                   -29-



of transfer of or in exchange for or in lieu of any other Security shall carry
the rights to interest accrued and unpaid, and to accrue (including in each such
case Additional Interest), which were carried by such other Security.

SECTION 308.  Persons Deemed Owners.

            Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee shall treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and (subject to
Section 307) interest (including Additional Interest) on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309.  Cancellation.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly cancelled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities held
by the Trustee shall be disposed of as directed by a Company Order.

SECTION 310.  Computation of Interest.

            Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months and, for any
period shorter than a full monthly period, shall be computed on the basis of the
actual number of days elapsed in such period.

SECTION 311.  Right of Set-Off.

            Notwithstanding anything to the contrary in this
Indenture, the Company shall have the right to set-off any





<PAGE>


                                   -30-



payment it is otherwise required to make hereunder to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under a Parent Guarantee.

SECTION 312.  CUSIP Numbers.

            The Company in issuing the Securities of any series may use "CUSIP"
numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP"
numbers in notices of redemption 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 Securities or as contained in any notice
of a redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                           SATISFACTION AND DISCHARGE

SECTION 401.  Satisfaction and Discharge of Indenture.

            This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

            (1)         either

            (a) all Securities theretofore authenticated and delivered (other
      than (i) Securities which have been destroyed, lost or stolen and which
      have been replaced or paid as provided in Section 306 and (ii) Securities
      for whose payment money or U.S. Government Obligations have theretofor
      been deposited in trust or segregated and held in trust by the Company and
      thereafter repaid to the Company or discharged from such trust, as
      provided in Section 1003) have been delivered to the Trustee for
      cancellation; or

            (b)   all such Securities not theretofore
      delivered to the Trustee for cancellation:

                  (i)   have become due and payable; or

                 (ii)   will become due and payable at
            their Stated Maturity within one year; or

                (iii) are to be called for redemption within one year under
            arrangements satisfactory to the Trustee for the giving of notice of
            redemption by the Trustee in the name, and at the expense, of the
            Company

      and the Company, in the case of (i), (ii) or (iii) above, has deposited or
      caused to be deposited with the Trustee as trust funds (a) money in the
      necessary amount or (b) U.S. Government Obligations, the principal of and
      the interest on which when due, and without any regard to reinvestment
      thereof, in the opinion of an independent accountant, and, in the opinion
      of the officers of the Company executing an Officers' Certificate to that
      effect, will provide moneys which, together with the moneys, if any,
      deposited with or held by the Trustee, shall be sufficient to pay when due
      the principal of, premium, if any, and interest due and to become due on
      said Securities or portions thereof on the Redemption Date or the Stated
      Maturity thereof, as the case may be, in trust to pay and discharge the
      entire indebtedness on such Securities not theretofore delivered to the
      Trustee for cancellation, for principal and interest (including Additional
      Interest to the date of deposit) to the date of such deposit (in the case
      of Securities which have become due and payable) or to the Stated Maturity
      or Redemption Date, as the case may be;

            (2)   the Company has paid or caused to be
      paid all other sums payable hereunder by the
      Company; and

            (3) the Company has delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent herein provided for relating to the satisfaction and discharge
      of this Indenture have been complied with.






<PAGE>


                                   -32-



Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607 and, if money or
U.S. Government Obligations shall have been deposited with the Trustee pursuant
to subclause (b) of clause (1) of this Section, the obligations of the Trustee
under Section 402 and the last paragraph of Section 1003 shall survive.

SECTION 402.  Application of Trust Money.

            Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal and interest for whose payment such deposited money and the money from
U.S. Government Obligations have been deposited with the Trustee.

SECTION 501.  Events of Default.

            "Event of Default," wherever used herein with respect to Securities
of any series, means any one of the following events that has occurred and is
continuing (whatever the reason for such Event of Default and whether it shall
be occasioned by the provisions of Article Eleven or be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order

governmental body):

            (1) failure for 30 days to pay any interest on the Securities of
      that series, including any Additional Interest in respect thereof, when
      due (subject to the deferral of any due date in the case of an Extension
      Period); or

            (2) failure to pay any principal on the Securities of that series
      when due whether at Stated Maturity, upon redemption, by declaration of
      acceleration or otherwise; except that, in the





<PAGE>


                                   -33-



      event of an optional redemption, the failure to redeem any Security which
      is the result of the Company's failure to deposit on or before the
      Redemption Date with the Trustee (and/or having irrevocably directed the
      Trustee to apply, from money held by it available to be used for the
      redemption of Securities) an amount in cash sufficient to redeem all of
      the Securities to be redeemed, shall not be an Event of Default, but shall
      be deemed a rescission of the call for redemption; or

            (3) failure to observe or perform in any material respect any other
      covenant relating to a particular series contained in this Indenture for
      90 days after written notice to the Company from the Trustee or the
      holders of at least 25% in principal amount of the Outstanding Securities
      of that series; or

            (4) a decree or order is entered by a court having jurisdiction in
      the premises (i) for relief in respect of the Company in an involuntary
      case or proceeding under the Federal Bankruptcy Code or any other federal
      or state bankruptcy, insolvency, reorganization or similar law or (ii)
      adjudging the Company a bankrupt or insolvent, or seeking reorganization,
      arrangement, adjustment or composition of or in respect of the Company
      under the Federal Bankruptcy Code or any other applicable federal or state
      law, or appointing a custodian, receiver, liquidator, assignee, trustee or
      sequestrator (or other similar official) of the Company or of any
      substantial part of any of its properties, or ordering the winding up or
      liquidation of any of its affairs, and any such decree or order remains
      unstayed and in effect for a period of 60 consecutive days; or

            (5) the Company institutes a voluntary case or proceeding under the
      Federal Bankruptcy Code or any other applicable federal or state law or
      any other case or proceedings to be adjudicated a bankrupt or insolvent,
      or the Company consents to the entry of a decree or order for relief in
      respect of the Company in any involuntary case or proceeding under the
      Federal Bankruptcy Code or





<PAGE>


                                   -34-



      any other applicable federal or state law or to the institution of
      bankruptcy or insolvency proceedings against the Company, or the Company
      files a petition or answer or consent seeking reorganization or relief
      under the Federal Bankruptcy Code or any other applicable federal or state
      law, or consents to the filing of any such petition or to the appointment
      of or taking possession by a custodian, receiver, liquidator, assignee,
      trustee or sequestrator (or other similar official) of the Company or of
      any substantial part of its property, or makes an assignment for the
      benefit of creditors, or admits in writing its inability to pay its debts
      generally as they become due or takes corporate action in furtherance of
      any such action.


SECTION 502.  Acceleration of Maturity;
                Rescission and Annulment.

            If an Event of Default with respect to the Securities of any series
at the time Outstanding occurs and is continuing, then and in every such case,
the Trustee or the Holders of not less than 25% in aggregate principal amount of
the Outstanding Securities of that series or the holders of at least 25% in
aggregate liquidation amount of the Preferred Securities then outstanding of the
Trust to which such series of securities has been issued shall have the right to
declare the principal of and the interest (including any Additional Interest) on
all the Securities of that series and any other amounts payable hereunder to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders or the holders of such Preferred Securities) and
shall have the right to enforce any and all other rights of Holders of
Securities of that series as creditors with respect to the Securities of that
series. Upon any such declaration, such principal and all accrued interest shall
become immediately due and payable.

            At any time after such a declaration of acceleration has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter provided in this Article, the Holders of a
majority in principal amount of the Outstanding Securities of that series, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:





<PAGE>


                                   -35-



            (1)   the Company has paid or deposited with the
      Trustee a sum sufficient to pay,

                  (A)   all overdue interest (including any
            Additional Interest) on all Securities of that
            series,

                  (B) the principal of any Securities which have become due
            otherwise than by such declaration of acceleration and interest
            thereon at the rate borne by such Securities, and

                  (C) all sums paid or advanced by the Trustee hereunder and the
            reasonable compensation, expenses, disbursements and advances of the
            Trustee, its agents and counsel; and

            (2) all Events of Default with respect to Securities of that series,
      other than the nonpayment of the principal of Securities of that series
      which have become due solely by such declaration of acceleration, have
      been cured or waived as provided in Section 513.

            No such rescission shall affect any subsequent default or impair any
right consequent thereon.

SECTION 503.  Collection of Indebtedness and Suits
                for Enforcement by Trustee.

            The Company covenants that if

            (1) default is made in the payment of any interest (including any
      Additional Interest) on any Security when such interest becomes due and
      payable and such default continues for a period of 30 days (subject to the
      deferral of any due and payable interest in the case of an Extension
      Period), or

            (2)   default is made in the payment of the principal
      of any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest (including any Additional Interest), at
the rate borne by the Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses





<PAGE>


                                   -36-



of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

            If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.  Trustee May File Proofs of Claim.

            In case of any judicial proceeding relating to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized 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
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

            No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 505.  Trustee May Enforce Claims Without
                Possession of Securities.

            All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.  Application of Money Collected.

            Subject to Article Eleven, any money or U.S. Government Obligations
collected by the Trustee pursuant to this Article shall be applied in the
following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal or interest (including any
Additional Interest), upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

            FIRST:  To the payment of all amounts due the
      Trustee under Section 607;

            SECOND: To the payment of the amounts then due and unpaid for
      principal of and interest (including any Additional Interest) on the
      Securities in respect of which or for the benefit of which such money has
      been collected, ratably, without preference or priority of any kind,
      according to the amounts due and payable on such Securities for principal
      and interest (including any Additional Interest), respectively; and

            THIRD:  The balance, if any, to the Company.

SECTION 507.  Limitation on Suits.

            No Holder of any Security of any series or any holder of Preferred
Securities of the Trust to which such series of Securities has been issued shall
have any right to institute any proceeding, judicial or otherwise, with respect

Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless

            (1) such Holder or holder of Preferred Securities has previously

      respect to Securities of that series;

            (2) the Holders of not less than 25% in principal amount of the

            (4) the Trustee for 60 days after its receipt of such notice,
      request and offer of indemnity has failed to institute any such
      proceeding; and

            (5) no direction inconsistent with such written request has been
      given to the Trustee during such 60-day period by the Holders of a
      majority in principal amount of the Outstanding Securities of that series
      or the holders of a majority in aggregate liquidation amount of the

holders of Preferred Securities or to enforce any right under this Indenture,
except in the manner herein

provided and for the equal and ratable benefit of all the
Holders or holders of Preferred Securities.

SECTION 508.  Unconditional Right of Holders to
                Receive Principal and Interest.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 307) interest
(including any Additional Interest) on such Security on the Stated Maturity
(subject to the deferral of any due date for the payment of interest in the case
of an Extension Period) expressed in such Security (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

SECTION 509.  Restoration of Rights and Remedies.

            If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture, and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holder shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holder shall continue
as though no such proceeding had been instituted.

Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511.  Delay or Omission Not Waiver.

            No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.  Control by Holders.

            The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, provided that

            (1)   such direction shall not be in conflict
      with any rule of law or with this Indenture; and

            (2) the Trustee may take any other action deemed proper by the
      Trustee which is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.

            Subject to Sections 902 and 905 hereof, the Holders of not less than
a majority in principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series waive any past
default hereunder and its consequences, except a default

            (1) in the payment of the principal of or interest (including any
      Additional Interest) on any Security of such series (unless such default
      has been cured and a sum sufficient to pay all matured installments of
      interest and principal due otherwise than by acceleration have been
      deposited with the Trustee); or

            (2) in respect of a covenant or provision hereof which under Article
      Nine cannot be modified or amended without the consent of the Holder of
      each Outstanding Security of such series affected.





<PAGE>


                                   -41-



            Upon any such waiver, such default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.

            In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such court
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in the
Trust Indenture Act; provided, that neither this Section nor the Trust Indenture
Act shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company or the Trustee or
in any suit for the enforcement of the right to receive the principal of and
interest (including any Additional Interest) on any Security.

SECTION 515.  Waiver of Stay or Extension Laws.

            The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 601.  Certain Duties and Responsibilities.

            (1)   Except during the continuance of an
      Event of Default,






<PAGE>


                                   -42-



                  (A) the Trustee undertakes to perform such duties and only
            such duties as are specifically set forth in this Indenture, and no
            implied covenants or obligations shall be read into this Indenture
            against the Trustee; and

                  (B) in the absence of bad faith on its part, the Trustee may
            conclusively rely, as to the truth of the statements and the
            correctness of the opinions expressed therein, upon certificates or
            opinions furnished to the Trustee and conforming to the requirements
            of this Indenture; but in the case of any such certificates or
            opinions which by any provisions hereof are specifically required to
            be furnished to the Trustee, the Trustee shall be under a duty to
            examine the same to determine whether or not they conform to the
            requirements of this Indenture.

            In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

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

                  (A)   this Subsection shall not be
            construed to limit the effect of Subsection
            (1) of this Section;

                  (B) the Trustee shall not be liable for any error of judgment
            made in good faith by a Responsible Officer, unless it shall be
            proved that the Trustee was negligent in ascertaining the pertinent
            facts; and

                  (C)   the Trustee shall not be liable
            with respect to any action taken or omitted





<PAGE>


                                   -43-



            to be taken by it in good faith in accordance with the direction of
            Holders pursuant to Section 512 relating to the time, method and
            place of conducting any proceeding for any remedy available to the
            Trustee, or exercising any trust or power conferred upon the
            Trustee, under this Indenture with respect to the Securities of such
            series.

            Notwithstanding the foregoing, no provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it 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.

            Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

SECTION 602.  Notice of Defaults.

            If any default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice
of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified in
Section 501(3) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof.

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

            For the purpose of this Section, the term "default" means any event
which is, or after notice or lapse of time or both would become, an Event of
Default with respect to Securities of such series.

      taking, suffering or omitting any action hereunder, the Trustee (unless
      other evidence be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an Officers' Certificate;

            (d) the Trustee may consult with counsel of its choice, which may be
      counsel to the Company, and the written advice of such counsel or any
      Opinion of 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;

            (e) the Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by this Indenture at the request or
      direction of any of the Holders pursuant to this Indenture, unless such

      against the costs, expenses and liabilities which might be incurred by it
      in compliance with such request or direction;

      instrument, opinion, report, notice, request, direction, consent, order,

      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally or by agent or attorney;

            (g) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or
      attorneys, and the Trustee shall not be responsible for any misconduct or
      negligence on the part of any agent or attorney appointed with due care by
      it hereunder; and

            (h) the Trustee shall not be liable for any action taken, suffered,
      or omitted to be taken by it in good faith and reasonably believed by it
      to be authorized or within the discretion or rights or powers conferred
      upon it by this Indenture.

SECTION 604.  Not Responsible for Recitals or
                Issuance of Securities.

            The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities. The Trustee shall not be accountable for the use
or application by the Company of Securities or the proceeds thereof.

            The Trustee, any Paying Agent, any Securities Registrar, or any
other agent of the Company, in its individual or any other capacity, may become
the owner or pledgee of Securities and, subject to Sections 608 and 613, may
otherwise deal with the Company with the same rights it would have if it

                                   -46-



were not Trustee, Paying Agent, Security Registrar, or such
other agent.

SECTION 606.  Money Held in Trust.

            Money held by the Trustee in trust hereunder need not be segregated

SECTION 607.  Compensation and Reimbursement.

            The Company agrees

            (1) to pay to the Trustee from time to time such compensation as the
      Company and the Trustee shall from time to time agree in writing for all
      services rendered by it hereunder (which compensation shall not be limited
      by any provision of law in regard to the compensation of a trustee of an
      express trust);

            (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with any provision

To secure the Trustee's rights under this Section, the Trustee shall have a lien
against any money or other property collected hereunder. The provisions of this
Section shall survive the termination of this Indenture.

SECTION 608.  Disqualification; Conflicting Interests.

            If the Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the 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 Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

SECTION 609.  Corporate Trustee Required; Eligibility.

            There shall at all times be a Trustee hereunder with respect to the
Securities of each series, which may be a Trustee hereunder for Securities of
one or more other series. Each Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital
and surplus of at least $50,000,000. If any such Person publishes reports of

capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610.  Resignation and Removal;
                Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
      successor Trustee pursuant to this Article shall become effective until
      the acceptance of appointment by such successor Trustee under Section 611.

            (b)   The Trustee may resign at any time with
      respect to the Securities of one or more series by





<PAGE>


                                   -48-



      giving written notice thereof to the Company. If an instrument of
      acceptance by a successor Trustee shall not have been delivered to the
      Trustee within 60 days after the giving of such notice of resignation, the
      resigning Trustee may petition any court of competent jurisdiction for the
      appointment of a successor Trustee with respect to the Securities of such
      series.

            (c) The Trustee may be removed at any time with respect to the
      Securities of any series by Act of the Holders of a majority in principal
      amount of the Outstanding Securities of such series, delivered to the
      Trustee and to the Company.

            (d)   If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
            written request therefor by the Company or by any Holder who has
            been a bona fide Holder of a Security for at least six months, or

                  (2) the Trustee shall cease to be eligible under Section 609
            and shall fail to resign after written request therefor by the
            Company or by any such Holder, or

                  (3) the Trustee shall become incapable of acting or shall be
            adjudged a bankrupt or insolvent or a receiver of the Trustee or of
            its property shall be appointed or any public officer shall take
            charge or control of the Trustee or of its property or affairs for
            the purpose of rehabilitation, conservation or liquidation, or

                  (4)   an Event of Default has not
            occurred and is not continuing,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of such Holder and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee





<PAGE>


                                   -49-



with respect to all Securities and the appointment of a
successor Trustee or Trustees.

            (e) If the Trustee shall resign, be removed or become incapable of
      acting, or if a vacancy shall occur in the office of Trustee for any
      cause, with respect to the Securities of one or more series, the Company,
      by a Board Resolution, shall promptly appoint a successor Trustee or
      Trustees with respect to the Securities of that or those series (it being
      understood that any such successor Trustee may be appointed with respect
      to the Securities of one or more or all of such series and that at any
      time there shall be only one Trustee with respect to the Securities of any
      particular series). If, within one year after such resignation, removal or
      incapability, or the occurrence of such vacancy, a successor Trustee with
      respect to the Securities of any series shall be appointed by Act of the
      Holders of a majority in principal amount of the Outstanding Securities of
      such series delivered to the Company and the retiring Trustee, the
      successor Trustee so appointed shall, forthwith upon its acceptance of
      such appointment, become the successor Trustee with respect to Securities
      of such series and supersede the successor Trustee with respect to the
      Securities of any series appointed by the Company. If no successor Trustee
      with respect to the Securities of any series shall have been so appointed
      by the Company or the Holders and accepted appointment in the manner
      hereinafter provided, any Holder who has been a bona fide Holder of a
      Security of such series for at least six months may, on behalf of himself
      and all others similarly situated, petition any court of competent
      jurisdiction for the appointment of a successor Trustee with respect to
      the Securities of such series.

            (f) The Company shall give notice of each resignation and each
      removal of the Trustee with respect to the Securities of any series and
      each appointment of a successor Trustee with respect to the Securities of
      any series to all Holders of Securities of such series in the manner
      provided in Section 106. Each notice shall include the





<PAGE>


                                   -50-



      name of the successor Trustee with respect to the Securities of such
      series and the address of such successor Trustee's Corporate Trust Office.

SECTION 611.  Acceptance of Appointment by Successor.

            Every successor Trustee with respect to all Securities appointed
hereunder shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
provided that, on request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its reasonable charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.

            In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the

hereunder separate and apart from any trust or





<PAGE>


                                   -51-



trusts hereunder administered by any other such Trustee; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

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

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

SECTION 612.  Merger, Conversion, Consolidation or Succession
              to Business.

conversion or consolidation to which the Trustee shall be a party, shall be the
successor of the Trustee hereunder, provided that such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

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

            In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of

                                   ARTICLE TEN

             COVENANTS; REPRESENTATIONS AND WARRANTIES

SECTION 1001.  Payment of Principal and Interest.

            The Company will duly and punctually pay the principal of and
interest on the Securities of each series in accordance with the terms of the
Securities and this Indenture.

SECTION 1002.  Maintenance of Office or Agency.

            The Company will maintain in the United States an office or agency
for each series of Securities where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served.
The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.

            The Company may also from time to time designate one or more other
offices or agencies (in the United States) where the securities of one or more
series may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the United States for each series
of Securities for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

SECTION 1003.  Money for Payments on Securities to
                  Be Held in Trust.

            If the Company shall at any time act as its own
Paying Agent with respect to any series of Securities, it will,





<PAGE>


                                   -60-



on or at the option of the Company before each due date of the principal of or
interest on any of the Securities of that series, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure so to act.

            Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to 12:00 noon, New York time, on each due
date of the principal of or interest on any Securities of that series, deposit
with a Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

            The Company will cause each Paying Agent for any series of
Securities other than the Trustee or the Company to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 1003, that such Paying Agent will (i)
comply with the provisions of the Trust Indenture Act applicable to it as a
Paying Agent and (ii) during the continuance of any default by the Company (or
any other obligor upon the Securities of that series) in the making of any
payment in respect of the Securities of that series, upon the written request of
the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent as such.

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of or interest on
any Security of any series and remaining unclaimed for two years after such
principal or interest has become due and payable shall be paid to the





<PAGE>


                                   -61-



Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease.

            The Trustee and the Paying Agent shall promptly pay to the Company
upon request any excess money or securities held by them at any time.

SECTION 1004.  Statement by Officers as to Default.

            The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance and observance of
any of the material terms, provisions or conditions of this Indenture (without
regard to any period of grace or requirement of notice provided hereunder) and,
if the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

SECTION 1005.  Additional Covenants.

            The Company covenants and agrees for the benefit of the Holders of
Securities of each series that it will not declare or pay any dividends or
distributions (other than dividends or distributions in capital stock of the
Company or other securities ranking junior in right of payment to the Securities
of a particular series) on, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock or any security ranking pari
passu with or junior in right of payment to the Securities of such series, or
make any guarantee payments with respect to the foregoing (other than pro rata
payments under the Parent Guarantee and any similar Parent Guarantees issued by
the Company on behalf of the holders of Preferred Securities issued by any
issuer holding Securities) or repurchase, or cause any of the Subsidiaries to
repurchase, any securities of the Company ranking pari passu with or junior in
right of payment to the Securities of such series (except for payments made on
any series of Securities upon the stated maturity of such Securities); provided
that the Company may redeem, purchase, acquire or make a liquidation payment
with respect to any of





<PAGE>


                                   -62-



its capital stock or any security ranking pari passu with or junior in right of
payment to the Securities of such series, make any guarantee payment with
respect to the foregoing or repurchase, or cause any of its subsidiaries to
repurchase, any security of the Company ranking pari passu with or junior in
right of payment to the Securities of such series with securities (or the
proceeds from the issuance of securities) having no higher ranking than the
capital stock or the other securities which are to be redeemed, purchased, or
acquired, with respect to which a liquidation payment is to be made, to which a
guarantee payment is to be made with respect to the foregoing or which are to be
repurchased, if at such time (i) there shall have occurred any event of which
the Company has actual knowledge that (a) with the giving of notice or the lapse
of time or both, would constitute an Event of Default hereunder with respect to
Securities of such series and (b) which the Company shall not have taken
reasonable steps to cure, (ii) the Company shall be in default with respect to
its payment of any obligations under a Parent Guarantee relating to the
Preferred Securities of the Trust corresponding to which the Securities of such
series have been issued or (iii) the Company shall have given notice of its
selection of an Extension Period as provided herein with respect to Securities
of such series and such period, or any extension thereof, shall have commenced
and be continuing.

            The Company also covenants, for the benefit of the Holders of
Securities of each series, (i) not to transfer ownership of the Common
Securities of the Trust to which the Securities of such series have been issued
to any person other than an Affiliate of the Company or a successor of the
Company permitted under Article Eight of this Indenture; provided that no such
transfer shall result in (x) the Trust being considered an "investment company"
that is required to be registered under the Investment Company Act of 1940, as
amended, or (y) the Trust not being taxed as a grantor trust for United States
Federal income tax purposes; (ii) not to voluntarily dissolve, wind up or
terminate such Trust, except in connection with a distribution of the Securities
of such series to the holders of the corresponding Preferred Securities in
liquidation of such Trust or in connection with certain mergers, consolidations
or amalgamations permitted by the Trust Agreement relating to such Trust and
(iii) to use its reasonable efforts, consistent with the terms and provisions of
such Trust Agreement, to cause such Trust to remain a grantor trust and not to
be classified as an association taxable as a corporation for United States
Federal income tax purposes.

assets and liabilities of the Company, then and in any such event:

            (1) the holders of Senior Indebtedness shall be entitled to receive
      payment in full in cash or cash equivalents of all amounts due or to
      become due on or in respect of all Senior Indebtedness, or provision shall
      be made for such payment in cash or cash equivalents, before the Holders
      of the Securities are entitled to receive any payment on account of
      principal of (or premium, if any) or interest on the Securities; and

            (2) any payment or distribution of assets of the Company of any kind
      or character, whether in cash, property or securities, by set-off or
      otherwise, to which the Holders or the Trustee would be entitled but for
      the provisions of this Article Eleven, including any such payment or
      distribution which may be payable or deliverable by reason of the payment
      of any other

                                   -64-



      indebtedness of the Company being subordinated to the payment of the
      Securities (except, so long as the effect of this parenthetical clause is
      not to cause the Securities to be treated in any case or proceeding or
      similar event described in Subsection (a), (b) or (c) of this Section 1102
      as part of the same class of claims as the Senior Indebtedness or any
      class of claims on a parity with or senior to the Senior Indebtedness, for
      any such payment or distribution of securities which (i) are unsecured,
      (ii) have an average life and final maturity no shorter than the average
      life and final maturity of the Securities and (iii) are subordinated, to
      at least the same extent as the Securities, to the payment of all Senior
      Indebtedness then outstanding), shall be paid by the liquidating trustee
      or agent or other person making such payment or distribution, whether a
      trustee in bankruptcy, a receiver or liquidating trustee or otherwise,
      directly to the holders of Senior Indebtedness or their Representative or
      Representatives or to the trustee or trustees under any indenture under
      which any instruments evidencing any of such Senior Indebtedness may have
      been issued, ratably according to the aggregate amounts remaining unpaid
      on account of the principal of, and premium, if any, and interest on, and
      other amounts due on or in connection with, the Senior Indebtedness to the
      extent necessary to make payment in full in cash or cash equivalents of
      all Senior Indebtedness remaining unpaid, after giving effect to any
      concurrent payment or distribution to the holders of such Senior
      Indebtedness; and

            (3) in the event that, notwithstanding the foregoing provisions of
      this Section, the Trustee or the Holder of any Security shall have
      received any such payment or distribution of assets of the Company of any
      kind or character, whether in cash, property or securities, including any
      such payment or distribution which may be payable or deliverable by reason
      of the payment of any other indebtedness of the Company being subordinated
      to the payment of the Securities, before all Senior Indebtedness is paid
      in full or payment thereof provided for, then and in such event such
      payment or distribution shall be paid over or delivered forthwith to the
      trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee,
      agent or other Person making payment or distribution of assets of the
      Company for application to the payment of all Senior Indebtedness
      remaining unpaid to





<PAGE>


                                   -65-



      the extent necessary to pay all Senior Indebtedness in full in cash or
      cash equivalents, after giving effect to any concurrent payment or
      distribution to or for the holders of Senior Indebtedness.

            The consolidation of the Company with, or the merger of the Company
into, another corporation or the liquidation or dissolution of the Company
following the conveyance, transfer or lease of its properties and assets
substantially as an entirety to another corporation upon the terms and
conditions set forth in Article Eight shall not be deemed a dissolution, winding
up, liquidation, reorganization, assignment for the benefit of creditors or
marshalling of assets and liabilities of the Company for the purposes of this
Section 1102 if the corporation formed by such consolidation or into which the
Company is merged or the corporation which acquires by conveyance, transfer or
lease such properties and assets substantially as an entirety, as the case may
be, shall, as a part of such consolidation, merger, conveyance, transfer or
lease, comply with the conditions set forth in Article Eight.

SECTION 1103.  No Payment When Senior Indebtedness in Default.

            (i) In the event of and during the continuation of any default in
the payment of principal of (or premium, if any) or interest on any Senior
Indebtedness or (ii) in the event that any other event of default with respect
to any Senior Indebtedness shall have occurred and be continuing and shall have
resulted in such Senior Indebtedness becoming or being declared due and payable
prior to the date on which it would otherwise have become due and payable, then
no payment shall be made by the Company on account of the principal of (or
premium, if any) or interest on the Securities or on account of the purchase or
redemption or other acquisition of Securities unless and until such payment
default shall have been cured or waived or shall have ceased to exist or such
acceleration shall have been rescinded or annulled or the holders of such Senior
Indebtedness or their agents have waived the benefits of this Section.

            In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, then and in such event such payment shall
be received and held in trust for the holders of Senior Indebtedness and shall
be paid over or delivered to the Representative of Senior






<PAGE>


                                   -66-



Indebtedness then outstanding to the extent necessary to pay in full in cash or
cash equivalents all Senior Indebtedness.

            The provisions of this Section shall not apply to any payment with
respect to which Section 1102 would be applicable.

SECTION 1104.  Payment Permitted if No Default.

            Nothing contained in this Article or elsewhere in this Indenture or
in any of the Securities shall prevent the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1102 or under the conditions
described in Section 1103, from making payments at any time of principal of (and
premium, if any) or interest on the Securities.

SECTION 1105.  Subrogation to Rights of Holders of
                  Senior Indebtedness.

            Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated (equally and ratably with the
holders of all indebtedness of the Company which by its express terms is
subordinated to Senior Indebtedness of the Company to the same extent as the
Securities are subordinated and which is entitled to like rights of subrogation)
to the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full. For purposes of such subrogation, no payments
or distributions to the holders of Senior Indebtedness of any cash, property or
securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebtedness
by Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

SECTION 1106.  Provisions Solely to Define Relative Rights.

            The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders of
the Securities the principal of (and premium, if any) and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the express limitations set forth in Article
Five and to the rights, if any, under this Article of the holders of Senior
Indebtedness (1) in any case, proceeding, dissolution, liquidation or other
winding up, assignment for the benefit of creditors or other marshalling of
assets and liabilities of the Company referred to in Section 1102, to receive,
pursuant to and in accordance with such Section, cash, property and securities
otherwise payable or deliverable to the Trustee or such Holder, or (2) under the
conditions specified in Section 1103, to prevent any payment prohibited by such
Section.

SECTION 1107.  Trustee to Effectuate Subordination.

            Each Holder of a Security by such Holder's acceptance thereof
authorizes and directs the Trustee on such Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination provided in
this Article and appoints the Trustee his attorney-in-fact for any and all such
purposes.

            With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Eleven, and no implied covenants
or obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of





<PAGE>


                                   -68-



Senior Indebtedness and, subject to the provisions of Section 601, the Trustee
shall not be liable to any holder of Senior Indebtedness if it shall pay over or
deliver to holders of Securities, the Company or any other Person money or
assets to which any holder of Senior Indebtedness shall be entitled by virtue of
this Article Eleven or otherwise.

SECTION 1108.  No Waiver of Subordination Provisions.

            No right of any present or future holder of any Senior Indebtedness
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

            Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
Eleven or the obligations hereunder of the Holders of the Securities to the
holders of Senior Indebtedness, do any one or more of the following: (a) change
the manner, place or terms of payment or extend the time of payment of, or renew
or alter, Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (b) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (c) release any Person liable in any manner for
the collection of Senior Indebtedness; and (d) exercise or refrain from
exercising any rights against the Company and any other Person.

SECTION 1109.  Notice to Trustee.

            The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities. Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payments to or by the Trustee in respect of the Securities, unless
and until the Trustee





<PAGE>


                                   -69-



shall have received written notice thereof at the Corporate Trust Office of the
Trustee from the Company or a holder of Senior Indebtedness or from any trustee,
fiduciary or agent therefore; and, prior to the receipt of any such written
notice, the Trustee, subject to the provisions of Section 602, shall be entitled
in all respects to assume that no such facts exist; provided, however, that if
the Trustee shall not have received the notice provided for in this Section 1109
at least three Business Days prior to the date upon which by the terms hereof
any money may become payable for any purpose (including, without limitation, the
payment of the principal of (and premium, if any) or interest on any Security),
then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such money and to apply the same
to the purpose for which such money was received and shall not be affected by
any notice to the contrary which may be received by it within three Business
Days prior to such date. Nothing in this Section 1109 shall limit the right of
the holders of Senior Indebtedness to recover payments as contemplated by
Sections 1102 and 1103.

            Subject to the provisions of Section 602, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing such Person to be a holder of Senior Indebtedness (or a trustee,
fiduciary or agent therefor) to establish that such notice has been given by a
holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor). In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

SECTION 1110.  Reliance on Judicial Order or
                        Certificate of Liquidating Agent.

            Upon any payment or distribution of assets of the Company referred
to in this Article, the Trustee, subject to the provisions of Section 602, and
the Holders of the





<PAGE>


                                   -70-



Securities shall be entitled to rely upon any order or decree entered by any
court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

SECTION 1111.  Rights of Trustee as a Holder of Senior
                  Indebtedness; Preservation of Trustee's Rights.

            The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

            Nothing in this Article shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 607.

SECTION 1112.  Article Applicable to Paying Agents.

            In case at any time any Paying Agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article Eleven in addition to or in place of the Trustee;
provided, however, that (i) Section 1111 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent and (ii)
any notice required by this Article Eleven to be given by the holders of, or a
Representative for, Senior Indebtedness need only be given to the Trustee and
not to any Paying Agent.

                                 ARTICLE TWELVE

                            REDEMPTION OF SECURITIES

SECTION 1201.  Applicability of Article.

            Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1202.  Election to Redeem; Notice to Trustee.

            The election of the Company to redeem any Securities pursuant to
Section 1201 shall be evidenced by a Board Resolution or in another manner
specified as contemplated by Section 301 for such Securities. In case of any
redemption at the election of the Company, the Company shall, at least 30 days
and no more than 90 days prior to the Redemption Date fixed by the Company,
notify the Trustee of such Redemption Date and of the principal amount of
Securities to be redeemed and provide a copy of the notice of redemption given
to Holders of Securities to be redeemed pursuant to Section 1204.

SECTION 1203.  Selection by Trustee of Securities
                  to Be Redeemed.

            If less then all the Securities of any series are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 90 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method (including pro rata or by
lot) as the Trustee shall deem fair and appropriate and which may provide for
the selection for redemption of portions (equal to $25 or any integral multiple
thereof) of the principal amount of the Securities of such series.

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to be
redeemed.

            The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in





<PAGE>


                                   -72-



whole or in part. In the case of any such redemption in part, the unredeemed
portion of the principal amount of the Security shall be in an authorized
denomination (which shall not be less than the minimum authorized denomination)
for such Security.

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

SECTION 1204.  Notice of Redemption.

            Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 90 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Securities Register. If at the time of mailing of any notice of redemption
the Company shall not have deposited with the Trustee (and/or irrevocably
directed the Trustee to apply, from money held by it available to be used for
the redemption of Securities) an amount in cash sufficient to redeem all of the
Securities to be redeemed, including accrued interest to such Redemption Date,
such notice shall state that the proposed redemption to which such notice
relates is subject to the deposit of such amount with the Trustee on or before
the Redemption Date.

            All notices of redemption shall identify the Securities to be
redeemed (including CUSIP number) and shall state:

            (1)   the Redemption Date,

            (2)   the Redemption Price,

            (3) if less than all the Outstanding Securities of any series
      consisting of more than a single Security are to be redeemed, the
      identification (and, in the case of the partial redemption of any such
      Securities, the principal amounts) of the particular Securities to be
      redeemed and, if less than all the Outstanding Securities of any series
      consisting of a single Security are to be redeemed, the principal amount
      of the particular Security to be redeemed,






<PAGE>


                                   -73-



            (4) that on the Redemption Date the Redemption Price will become due
      and payable upon each such Security to be redeemed and that interest
      thereon will cease to accrue on and after said date, and

            (5) the place or placement where such Securities are to be
      surrendered for payment of the Redemption Price.

            Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1205.  Deposit of Redemption Price.

            Prior to 12:00 noon, New York time, on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities which are to be redeemed on that date.

SECTION 1206.  Securities Payable on Redemption Date.

            Notice of redemption having been given as aforesaid and the Company
having on or before the Redemption Date deposited with the Trustee (and/or
having irrevocably directed the Trustee to apply, from money held by it
available to be used for the redemption of Securities) an amount in cash
sufficient to redeem all of the Securities to be redeemed, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date, such
Securities shall cease to bear interest. Upon surrender of any such Security for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest whose Stated
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.







<PAGE>


                                   -74-



            If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, such Security shall remain outstanding and
shall, until paid, bear interest from the Redemption Date at the rate borne by
the Security.

SECTION 1207.  Securities Redeemed in Part.

            Any Security which is to be redeemed only in part shall be
surrendered at a place of payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or such Holder's attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Security or Securities, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

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

            NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE
WITNESSETH:

            For and in consideration of the premises and the purchase of the
Series A Securities by the Holders thereof, it is mutually agreed, for the equal
and proportionate benefit of all Holders of the Series A Securities as follows:


                                   ARTICLE ONE

                 GENERAL TERMS OF THE SERIES A SECURITIES

SECTION 101.  Title; Stated Maturity; Interest.

            The aggregate principal amount of Securities which may be
authenticated and delivered under this First Supplemental Indenture is limited
to $103,092,775 except for Securities authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Section 303, 304, 305, 306, 906 or 1207 of the Indenture.

            The Securities shall be known and designated as the "7.85%
Deferrable Interest Subordinated Debentures, Series A due 2036" of the Company.
Their Stated Maturity shall be September 1, 2036, and they shall bear interest
at the rate of 7.85% per annum, from October 21, 1996 or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, as
the case may be, payable quarterly (subject to deferral as set forth herein), in
arrears, on March 1, June 1, September 1 and December 1 of each year, commencing
December 1, 1996 until the principal thereof is paid or made available for
payment. Additional Interest Attributable to Deferral will compound quarterly
and will accrue at the rate of 7.85% per annum on any interest installment in
arrears for more than one quarter or during an extension of an interest payment
period as set forth below. In the event that any date on which interest is
payable on the Securities is not a Business Day, then a payment of the interest
payable on such date will be made on the next succeeding day which is a Business
Day except that, if




<PAGE>


                                    -3-



such Business Day is in the next succeeding calendar year, such
Interest Payment Date shall be the immediately preceding Business Day (and
without any interest or other payment in respect of any such delay).

            The Company shall have the right, at any time while any Series A
Securities are outstanding, from time to time to extend the interest payment
period thereon for up to 20 consecutive quarters (the "Extension Period") during
which period interest will compound quarterly and the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which Extension Period the Company shall pay all interest then
accrued and unpaid thereon (together with Additional Interest Attributable to
Deferral at the rate specified for the Series A Securities to the extent
permitted by applicable law); provided that the Company shall not defer the
interest payment period with respect to Additional Interest Attributable to
Taxes and shall make payment thereof on the relevant Interest Payment Date;
provided further that during any such Extension Period, the Company shall not
declare or pay any dividends or distributions (other than dividends or
distributions in capital stock of the Company or other securities, including
other securities ranking junior in right of payment to the Series A Securities)
on, or redeem, purchase, acquire or make a liquidation payment with respect to,
any of its capital stock or any security ranking pari passu with or junior in
right of payment to the Series A Securities, or make any guarantee payment with
respect to the foregoing (other than pro rata payments under the Parent
Guarantee and any similar Parent Guarantees issued by the Company on behalf of
the holders of Preferred Securities issued by any issuer holding Securities) or
repurchase, or cause any of its Subsidiaries to repurchase, any security of the
Company ranking pari passu with or junior in right of payment to the Series A
Securities (except for payments made on any series of Securities upon the stated
maturity of such Securities); provided that the Company may redeem, purchase,
acquire or make a liquidation payment with respect to any of its capital stock
or any security ranking pari passu with or junior in right of payment to the
Series A Securities, make any guarantee payment with respect to the foregoing or
repurchase, or cause any of its subsidiaries to repurchase, any security of the
Company ranking pari passu with or junior in right of payment to the Series A
Securities with securities (or the proceeds from the issuance of securities)
having no higher ranking than the capital stock or the other securities which
are to be redeemed, purchased, or acquired, with respect to which a liquidation
payment is to be made, to




<PAGE>


                                    -4-



which a guarantee payment is to be made with respect to the foregoing or which
are to be repurchased. Prior to the termination of any such Extension Period,
the Company may further extend the interest payment period, provided that such
Extension Period together with all such previous and further extensions thereof
shall not exceed 20 consecutive quarters or extend beyond the Stated Maturity or
the Redemption Date of the Series A Securities. Upon the termination of any
Extension Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due, the Company may select a new Extension Period,
subject to the foregoing requirements. Except for Additional Interest
Attributable to Taxes, no interest shall be due and payable during an Extension
Period, except at the end thereof. The Company shall give the Series A Trust,
the Administrative Trustees of the Series A Trust and the Trustee notice of its
selection of such Extension Period, subject to the above requirements, at least
one Business Day prior to the earlier of (i) the related Interest Payment Date
or (ii) the date the Series A Trust is required to give notice to the New York
Stock Exchange or other applicable self-regulatory organization or to Holders of
the Series A Preferred Securities of the record date or the date such
distributions are payable, but in any event not less than one Business Day prior
to such record date. The Trustee shall promptly notify the Holders of the Series
A Preferred Securities and the Administrative Trustees of the Series A Trust of
the Company's selection of such an Extension Period.

            The principal of and interest on the Series A Securities shall be
payable at the office or agency of the Company in the United States maintained
for such purpose and at any other office or agency maintained by the Company for
such purpose in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that, at the option of the Company, payment of interest may
be made (i) by check mailed to the address of the Person entitled thereto as
such address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Securities
Register; provided further, that for so long as any Series A Security is
registered in the name of the Property Trustee, payment of principal (including
Redemption Price and interest) shall be made by wire transfer in immediately
available funds at such place and to such account as may be designated by the
Property Trustee.






<PAGE>


                                    -5-



            The Series A Securities shall be subordinated in right of payment to
Senior Indebtedness as provided in Article Eleven of the Indenture. The Series A
Securities shall be pari passu with the Parent Guarantee.

            The Series A Securities shall be redeemable as provided in Section
102 below and in Article Twelve of the Indenture.

SECTION 102.  Redemption.

            At any time on or after October 21, 2001, the Company shall have the
right to redeem the Series A Securities, in whole or in part, from time to time,
at a Redemption Price equal to 100% of the principal amount of Series A
Securities to be redeemed plus accrued but unpaid interest, including any
Additional Interest, if any, to the Redemption Date.

            If a Tax Event or an Investment Company Act Event shall occur and be
continuing or upon the event of the termination or liquidation of the Series A
Trust pursuant to an order for the dissolution, termination, or liquidation of
the Series A Trust entered by a court of competent jurisdiction, the Company
shall have the right to redeem the Series A Securities in whole but not in part,
at a Redemption Price equal to 100% of the principal amount thereof plus accrued
but unpaid interest, including Additional Interest, if any, to the Redemption
Date.

            For so long as the Series A Trust is the Holder of all Series A
Securities Outstanding, the proceeds of any redemption described in this Section
102 shall be used by the Series A Trust to redeem Series A Preferred Securities
in accordance with their terms. The Company shall not redeem the Series A
Securities in part unless all accrued and unpaid interest (including any
Additional Interest) has been paid in full on all Series A Securities
Outstanding for all quarterly interest periods terminating on or prior to the
Redemption Date.

SECTION 103.  Global Security.

            If the Series A Trust is not the sole Holder of the Series A
Securities, in order to utilize a book-entry-only system for all or any portion
of the Series A Securities, all or a portion of the Series A Securities may be
issued in the form of one or more fully-registered Global Securities for the







<PAGE>


                                    -6-



aggregate principal amount of such Series A Securities (the "Series A Global
Securities"), which Series A Global Securities shall be registered in the name
of the Depositary selected by the Company or in the name of such Depositary's
nominee. The initial Depositary shall be The Depository Trust Company. Each
Series A Global Security shall be delivered by the Trustee to the Depositary or
pursuant to the Depositary's instruction.

            If an event described under Clause (2) of Section 305 of the
Indenture shall occur, then this Section 103 shall no longer be applicable to
the Series A Global Securities, and the Company will execute, and the Trustee
will authenticate and deliver (subject to receipt of an Officer's Certificate
evidencing the Company's determination if the Company has exercised its rights
under Clause (2)(C) of Section 305), Series A Securities in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Series A Global
Securities in exchange for such Series A Global Securities. Upon the exchange of
Series A Global Securities for such Series A Securities in definitive registered
form, the Series A Global Securities shall be cancelled by the Trustee. Such
Series A Securities in definitive registered form issued in exchange for Series
A Global Securities pursuant to this Section 103 shall be registered in such
names and in such authorized denominations as the Depositary, pursuant to
instructions from its Direct or Indirect Participants or otherwise, shall
direct. The Trustee shall deliver such Series A Securities to the Persons in
whose names such Series A Securities are so registered.

            Except as provided below, owners solely of beneficial interests in a
Series A Global Security shall not be entitled to receive physical delivery of
Series A Securities in definitive form and will not be considered the Holders
thereof for any purpose under the Indenture.

            Members of or participants in the Depositary shall have no rights
under this Supplemental Indenture or the Indenture with respect to any Series A
Global Security held on their behalf by the Depositary, and such Depositary or
its nominee, as the case may be, may be treated by the Company, the Trustee, and
any agent of the Company or the Trustee as the Holder of such Series A Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
contained herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by the Depositary




<PAGE>


                                    -7-



or impair, as between the Depositary and its members or participants, the
operation of customary practices governing the exercise of the rights of a
Holder of any Series A Security, including without limitation the granting of
proxies or other authorization of participants to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action which
a Holder is entitled to give or take under the Indenture.


                                   ARTICLE TWO

                            FORM OF SERIES A SECURITY

            The Series A Securities are to be in substantially the following
form:

            SOUTHWESTERN PUBLIC SERVICE COMPANY, a corporation duly organized
and existing under the laws of the State of New Mexico (herein called the
"Company," which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
________________, or registered assigns, the principal sum of ________ DOLLARS
($________) on September 1, 2036 and to pay interest on said principal sum from
October 21, 1996 or from the most recent interest payment date (each such date,
an "Interest Payment Date") to which interest has been paid or duly provided
for, quarterly (subject to deferral as set forth herein) in arrears on March 1,
June 1, September 1 and December 1 of each year, commencing December 1, 1996, at
the rate of 7.85% per annum plus Additional Interest, if any, until the
principal hereof shall have become due and payable, and on any overdue
principal. The amount of interest payable for any period will be computed on the
basis of twelve 30-day months and a 360-day year and, for any period shorter
than a full monthly period, shall be computed on the basis of the actual




<PAGE>


                                    -8-



number of days elapsed in such period. In the event that any date on which
interest is payable on this Security is not a Business Day, then a payment of
the interest payable on such date will be made on the next succeeding day which
is a Business Day (and without any interest or other payment in respect of any
such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on the date the
payment was originally payable. A "Business Day" shall mean any day other than a
Saturday or a Sunday or a day on which banking institutions in the City of New
York are authorized or required by law or executive order to remain closed or a
day on which the Corporate Trust Office of the Trustee, the principal office of
the property trustee under the Trust Agreement or the principal office of the
Company is closed for business. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities, as defined in the Indenture) is registered
at the close of business on the Regular Record Date for such interest
installment, which shall be the close of business on the Business Day next
preceding such Interest Payment Date or, if this Security is issued in
certificated form, the close of business on the 15th day next preceding such
Interest Payment Date. Any such interest installment not so punctually paid or
duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in said
Indenture.

            The Company shall have the right at any time during the term of this
Security, from time to time, to extend the interest payment period of such
Security for up to 20 consecutive quarters (an "Extension Period"), during which
period interest will compound quarterly and the Company shall have the right to
make partial payments of interest on any Interest Payment Date, and at the end
of which Extension Period the Company shall pay all interest then accrued and
unpaid (together with



<PAGE>


                                    -9-



Additional Interest thereon to the extent that payment of such interest is
permitted by applicable law); provided that the Company shall not defer the
interest payment period with respect to Additional Interest Attributable to
Taxes; provided further that during any such Extension Period, the Company shall
not declare or pay any dividends or distributions (other than dividends or
distributions in capital stock of the Company or other securities ranking junior
in right of payment to the Securities) on, or redeem, purchase, acquire or make
a liquidation payment with respect to, any of its capital stock or any security
ranking pari passu with or junior in right of payment to this Security, or make
any guarantee payment with respect to the foregoing (other than pro rata
payments under the Parent Guarantee and any similar Parent Guarantees issued by
the Company on behalf of the holders of Preferred Securities issued by any
issuer holding Securities) or repurchase, or cause any of its Subsidiaries to
repurchase, any security of the Company ranking pari passu with or junior in
right of payment to this Security (except for payments made on any series of
securities upon the stated maturity of such securities); provided that the
Company may redeem, purchase, acquire or make a liquidation payment with respect
to any of its capital stock or any security ranking pari passu with or junior in
right of payment to this Security, make any guarantee payment with respect to
the foregoing or repurchase, or cause any of its subsidiaries to repurchase, any
security of the Company ranking pari passu with or junior in right of payment to
this Security with securities (or the proceeds from the issuance of securities)
having no higher ranking than the capital stock or the other securities which
are to be redeemed, purchased, or acquired, with respect to which a liquidation
payment is to be made, to which a guarantee payment is to be made with respect
to the foregoing or which are to be repurchased. Prior to the termination of any
such Extension Period, the Company may further extend the interest payment
period, provided that such Extension Period together with all such previous and
further extensions thereof shall not exceed 20 consecutive quarters or extend
beyond the maturity of this Security. Upon the termination of any such Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due, the Company may select a new Extension Period,
subject to the foregoing requirements. No interest shall be due and payable
during an Extension Period except at the end thereof. The Company shall give the
Holder of this Security and the Trustee notice of its selection of an Extension
Period at least one Business Day prior to the earlier of (i) the Interest
Payment Date or (ii) the date the Series A Trust is required to give notice to




<PAGE>


                                   -10-



the New York Stock Exchange or other applicable self-regulatory organization or
to holders of the Series A Preferred Securities of the record date or the date
such distributions are payable, but in any event not less than one Business Day
prior to such record date.

            Payment of the principal of and interest on this Security will be
made at the office or agency of the Company maintained for that purpose in
Wilmington, Delaware, in such coin or currency of the United States of America
as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest
may be made (i) by check mailed to the address of the Person entitled thereto as
such address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Securities
Register.

            The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Security is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on such Holder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee such Holder's
attorney-in-fact for any and all such purposes. Each Holder hereof, by such
Holder's acceptance hereof, waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture of each holder of
Senior Indebtedness, whether now outstanding or hereafter incurred, and waives
reliance by each such Holder upon said provisions.

            Reference is hereby made to the further provisions of the Indenture
summarized on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

            Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

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



                   FORM OF REVERSE OF SERIES A SECURITY

            This Security is one of a duly authorized issue of Securities of the
Company, designated as its 7.85% Deferrable Interest Subordinated Debentures,
Series A, due 2036 (therein called the "Securities"), limited in aggregate
principal amount to $103,092,775 issued under an Indenture, dated as of October
21, 1996 supplemented by a First Supplemental Indenture, dated as of October 21,
1996 (herein called the "Indenture"), between the Company and Wilmington Trust
Company, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and such supplemental
indentures reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

            All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

            At any time on or after October 21, 2001, the Company shall have the
right, subject to the terms and conditions of Article Twelve of the Indenture,
to redeem this Security at the option of the Company, without premium or
penalty, in whole or in part, at a Redemption Price equal to 100% of the
principal amount to be redeemed plus accrued but unpaid interest, 






<PAGE>


                                   -12-



including Additional Interest, if any, to the Redemption Date. If a Tax Event or
an Investment Company Event (as defined in the Indenture) shall occur and be
continuing, the Company shall have the right, subject to the terms and
conditions of Article Twelve of the Indenture, to redeem this Security at the
option of the Company, without premium or penalty, in whole but not in part, at
a Redemption Price equal to 100% of the principal amount thereof plus accrued
but unpaid interest, including Additional Interest, if any, to the Redemption
Date. Any redemption pursuant to this paragraph will be made upon not less than
30 nor more than 90 days' notice, at the Redemption Price. If the Securities are
only partially redeemed by the Company, the Securities will be redeemed pro
rata, by lot or in such other manner as the Trustee shall deem appropriate and
fair in its discretion and that may provide for the selection of a portion or
portions (equal to twenty-five U.S. dollars ($25) or any integral multiple
thereof) of the principal amount of any Security.

            In the event of the redemption of this Security in part only, a new
Security or Securities for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

            If an Event of Default with respect to the Securities shall occur
and be continuing, the principal of the Securities may be declared due and
payable in the manner, with the effect and subject to the conditions provided in
the Indenture.

            The Indenture contains provisions for satisfaction and discharge at
any time of the entire indebtedness of this Security upon compliance by the
Company with certain conditions set forth in the Indenture.

            The Indenture contains provisions permitting the Company and the
Trustee, with the consent of Holders of the Securities of each series to be
affected of not less than a majority in principal amount of the Outstanding
Securities of such series, to modify the Indenture in a manner affecting the
rights of the Holders of the Securities of such series; provided that no such
modification may, without the consent of the Holder of each Outstanding Security
affected thereby, (i) extend the fixed maturity of the Securities, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest (other than pursuant to an Extension Period) thereon, or reduce any
premium payable upon the redemption thereof, or (ii) reduce the percentage of
principal amount

                                   -13-



of the Securities, the Holders of which are required to consent to any such
modification of the Indenture. The Indenture also contains provisions permitting
Holders of specified percentages in principal amount of the Securities of each
series at the time Outstanding, on behalf of the Holders of all Securities of
such series, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

            No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

            As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the
Securities Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company, Wilmington Trust Company, 1100
North Market Street, Wilmington, Delaware 19890, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar duly executed by, the Holder hereof or the
Holder's attorney thereunto duly authorized in writing, and thereupon one or
more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees. No
service charge shall be made for any such registration of transfer or exchange,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.

            Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security shall be overdue, and none
of the Company, the Trustee or any such agent shall be affected by notice to the
contrary.

            The Securities are issuable only in registered form without coupons
in denominations of $25 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

            A director, officer, employee or stockholder, as such, of the
Company shall not have any liability for any obligations of the Company under
the Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each holder by accepting a
Security waives and releases all such liability. The waiver and release are part
of the consideration for the issuance of the Securities.

            THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW.

Holders of all of the Preferred Securities, waive any past Event of Default and
its consequences. Upon such waiver, any such Event of Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been

extend to any subsequent or other default or Event of Default or impair any
right consequent thereon.

            SECTION 2.7.  Event of Default; Notice.

            (a) The Trustee shall, within 90 days after the occurrence of an

Holders of the Preferred Securities.

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

            SECTION 2.8. Conflicting Interests. The Trust Agreement shall be

            (a) This Guarantee Agreement shall be held by the Trustee for the
benefit of the Holders of the Preferred Securities, and the Trustee shall not
transfer this Guarantee Agreement to any Person except a Holder of Preferred
Securities exercising his or her rights pursuant to Section 5.4 or to a
Successor Trustee on acceptance by such Successor Trustee of its appointment to
act as Successor Trustee. The right, title and interest of the Trustee shall
automatically vest in any Successor Trustee, and such vesting and cessation of
title shall be effective whether or not conveyancing documents have been
executed and delivered pursuant to the appointment of such Successor Trustee.

            (b) If an Event of Default has occurred and is continuing, the
Trustee shall enforce this Guarantee Agreement for the benefit of the Holders of

            (c) The 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
Guarantee Agreement, and no implied covenants shall be read into this Guarantee
Agreement against the Trustee. In case an Event of Default has occurred (that
has not been cured or waived pursuant to Section 2.6), the Trustee shall
exercise such of the rights and powers vested in it by this Guarantee Agreement,
and use the same

degree of care and skill in its exercise thereof, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

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

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

                  (A) the duties and obligations of the Trustee shall be
            determined solely by the express provisions of this Guarantee
            Agreement, and the Trustee shall not be liable except for the
            performance of such duties and obligations as are specifically set
            forth in this Guarantee Agreement; and

                  (B) in the absence of bad faith on the part of the Trustee,
            the 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 Trustee and conforming to
            the requirements of this Guarantee Agreement; but in the case of any
            such certificates or opinions that by any provision hereof are
            specifically required to be furnished to the Trustee, the Trustee
            shall be under a duty to examine the same to determine whether or
            not they conform to the requirements of this Guarantee Agreement;

           (ii) the Trustee shall not be liable for any error of judgment made
      in good faith by a Responsible Officer of the Trustee, unless it shall be
      proved that the Trustee was negligent in ascertaining the pertinent facts
      upon which such judgment was made;

          (iii) the 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 a Majority in Liquidation Amount of the
      Preferred Securities relating to the time, method and place of conducting
      any proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee under this Guarantee Agreement;
      and






<PAGE>


                                    -9-


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

            SECTION 3.2.  Certain Rights of Trustee.

            (a)   Subject to the provisions of Section 3.1:

            (i) the Trustee may rely and shall be fully protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or
      document believed by it to be genuine and to have been signed, sent or
      presented by the proper party or parties;

           (ii)  any direction or act of the Guarantor
      contemplated by this Guarantee Agreement shall be
      sufficiently evidenced by an Officers' Certificate;

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

           (iv) the Trustee may consult with counsel of its choice, and the
      written advice or opinion of such counsel with respect to legal matters
      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
      accordance with such advice or opinion; such counsel may be counsel to
      the Guarantor or any of its Affiliates and may include any of its
      employees; the Trustee shall have the right at any time to seek
      instructions concerning the administration of this Guarantee Agreement
      from any court of competent jurisdiction;






<PAGE>


                                   -10-


            (v) the Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by this Guarantee Agreement at the request
      or direction of any Holder, unless such Holder shall have provided to the
      Trustee such adequate security and indemnity as would satisfy a reasonable
      person in the position of the Trustee, against the costs, expenses
      (including attorneys' fees and expenses) and liabilities that might be
      incurred by the Trustee in complying with such request or direction,
      including such reasonable advances as may be requested by the Trustee;
      provided that, nothing contained in this Section 3.2(a)(v) shall be
      interpreted so as to relieve the Trustee, upon the occurrence of an Event
      of Default, of its obligation to exercise the rights and powers vested in
      it by this Guarantee Agreement;

           (vi) the 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, direction, consent, order,
      bond, debenture, note, other evidence of indebtedness or other paper or
      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit;

          (vii) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or
      attorneys, and the Trustee shall not be responsible for any misconduct or
      negligence on the part of any agent or attorney appointed with due care by
      it hereunder; and

         (viii) whenever in the administration of this Guarantee Agreement the
      Trustee shall deem it desirable to receive instructions with respect to
      enforcing any remedy or right or taking any other action hereunder, the
      Trustee (i) may request instructions from the Holders of the Preferred
      Securities, (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.

            (b) No provision of this Guarantee Agreement shall be deemed to
impose any duty or obligation on the Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Trustee shall be
unqualified or incompetent in accordance with applicable law, 



<PAGE>


                                   -11-


to perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Trustee shall be
construed to be a duty.

            (c) The Guarantor agrees to indemnify the Trustee for, and to hold
it harmless against, any and all loss, damage, claim, liability or expense,
including taxes (other than taxes based on the income of the Trustee) incurred
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of this Guaranty Agreement, including the
costs and expenses of defending itself against any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder. The Trustee's right to indemnification hereunder shall survive the
termination of this Guaranty Agreement.

            SECTION 4.1.  Trustee; Eligibility.

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

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

           (ii) be a Person that is eligible pursuant to the Trust Indenture Act
      to act as such and has a combined capital and surplus of at least
      $50,000,000 and has its Corporate Trust office in the continental United
      States. If such Person publishes reports of condition at least annually,
      pursuant to law or to the requirements of said supervising or examining
      authority, then, for the purposes of this Section 4.1(a)(ii), 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.

            (b) If at any time the Trustee shall cease to be eligible to so act
under Section 4.1(a), the Trustee shall immediately resign in the manner and
with the effect set out in Section 4.2(c).

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

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

            SECTION 4.2.  Appointment, Removal and Resignation of
Trustee.

            (a) Subject to Section 4.2(b), the Trustee may be appointed or
removed without cause at any time by the Guarantor except following the
occurrence and during the continuation of an Event of Default.

            (b) The Trustee shall not be removed until a Successor Trustee has
been appointed and has accepted such appointment by written instrument executed
by such Successor Trustee and delivered to the Guarantor.

            (c) The Trustee appointed to office shall hold office until a
Successor Trustee shall have been appointed or until its removal or
registration. The Trustee may resign from office (without need for prior or
subsequent accounting) by an instrument in writing executed by the Trustee and
delivered to the Guarantor, which resignation shall not take effect until a
Successor Trustee has been appointed and has accepted such appointment by
instrument in writing executed by such Successor Trustee and delivered to the
Guarantor and the resigning Trustee.

            (d) If no Successor Trustee shall have been appointed and accepted
appointment as provided in this Section 4.2 within 60 days after delivery to the
Guarantor of an instrument of resignation, the resigning Trustee may petition
any court of competent jurisdiction for appointment of a Successor Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Trustee.


                               ARTICLE 5.

full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim which the Issuer may have or assert, other than
the defense of payment. The Guarantor's obligation to make a Guarantee Payment
may be satisfied by direct payment











<PAGE>
                                   -13-


of the required amounts by the Guarantor to the Holders or by causing the Issuer
to pay such amounts to the Holders.

            SECTION 5.2. Waiver of Notice and Demand. The Guarantor hereby
waives notice of acceptance of this Guarantee Agreement and of any liability to
which it applies or may apply, presentment, demand for payment, any right to
require a proceeding first against the Issuer or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.

            SECTION 5.3. Obligations Not Affected. The obligation of the
Guarantor to make the Guarantee Payments under this Guarantee Agreement shall in
no way be affected or impaired by reason of the happening from time to time of
any of the following:

            (a) the release or waiver, by operation of law or otherwise, of the
      performance or observance by the Issuer of any express or implied
      agreement, covenant, term or condition relating to the Preferred
      Securities to be performed or observed by the Issuer;

            (b) the extension of time for the payment by the Issuer of all or
      any portion of the Distributions, Redemption Price, Liquidation
      Distribution or any other sums payable under the terms of the Preferred
      Securities or the extension of time for the performance of any other
      obligation under, arising out of, or in connection with, the Preferred
      Securities (other than an extension of time for payment of Distributions,
      Redemption Price, Liquidation Distribution or other sum payable that
      results from the extension of any interest payment period on the
      Debentures permitted by the Indenture);

            (c) any failure, omission, delay or lack of diligence on the part of
      the Holders to enforce, assert or exercise any right, privilege, power or
      remedy conferred on the Holders pursuant to the terms of the Preferred
      Securities, or any action on the part of the Issuer granting indulgence or
      extension of any kind;

            (d) the voluntary or involuntary liquidation, dissolution, sale of
      any collateral, receivership, insolvency, bankruptcy, assignment for the
      benefit of creditors, reorganization, arrangement, composition or
      readjustment of 






<PAGE>


                                   -14-


      the debt of, or other similar proceedings affecting, the
      Issuer or any of the assets of the Issuer;

            (e)   any invalidity of, or defect or deficiency in,
      the Preferred Securities;

            (f)   the settlement or compromise of any obligation
      guaranteed hereby or hereby incurred; or

            (g) any other circumstance whatsoever that might otherwise
      constitute a legal or equitable discharge or defense of a guarantor other
      than the defense of payment, it being the intent of this Section 5.3 that
      the obligations of the Guarantor hereunder -- to the limited extent set
      forth herein -- shall be absolute and unconditional under any and all
      circumstances.

There shall be no obligation of the Holders to give notice to, or obtain consent
of, the Guarantor with respect to the happening of any of the foregoing.

that: (i) this Guarantee Agreement will be deposited with the Trustee to be held
for the benefit of the Holders of the Preferred Securities; (ii) the Trustee has
the right to enforce this Guarantee Agreement on behalf of the Holders of the
Preferred Securities; (iii) the Holders of a Majority in Liquidation Amount of
the Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee in respect of
this Guarantee Agreement or exercising any trust or power conferred upon the
Trustee under this Guarantee Agreement; and (iv) any Holder of the Preferred
Securities may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Guarantee Agreement, without first instituting a
legal proceeding against the Issuer or any other person or entity.

            SECTION 5.5. Guarantee of Payment. This Guarantee Agreement creates
a guarantee of payment and not of collection. This Guarantee Agreement will not
be discharged except by payment of the Guarantee Payments in full (without
duplication).

            SECTION 5.6. Subrogation. The Guarantor shall be subrogated to all
(if any) rights of the Holders of Preferred Securities against the Issuer in
respect of any amounts paid to the Holders by the Guarantor under this Guarantee
Agreement; provided, however, that the Guarantor shall not (except to the 



<PAGE>


                                   -15-


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

            SECTION 5.7. Independent Obligations. The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Issuer
with respect to the Preferred Securities and that the Guarantor shall be liable
as principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Guarantee Agreement notwithstanding the occurrence of any event
referred to in subsections (a) through (g), inclusive, of Section 5.3 hereof.


                               ARTICLE 6.

                              SUBORDINATION

            SECTION 6.1. Subordination. This Guarantee Agreement will constitute
an unsecured obligation of the Guarantor and will rank subordinate and junior in
right of payment to all Senior Indebtedness of the Guarantor. This Guarantee
Agreement will be pari passu with the Debentures.

            SECTION 6.2. Pari Passu. This Guarantee Agreement shall rank pari
passu with any similar Guarantee Agreements issued by the Guarantor on behalf of
the Holders of Preferred Securities issued by any other issuer holding
debentures issued under the Indenture.

                               ARTICLE 7.

                               TERMINATION

            SECTION 7.1. Termination. This Guarantee Agreement shall terminate
and be of no further force and effect upon: (i) full payment of the Redemption
Price of all Preferred Securities, (ii) the distribution of Debentures to

Notwithstanding the foregoing, this Guarantee Agreement will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
must restore payment of any sums paid with respect to the Preferred Securities
or under this Guarantee Agreement.


                               ARTICLE 8.

                              MISCELLANEOUS

            SECTION 8.1. Successors and Assigns. All guarantees and agreements
contained in this Guarantee Agreement shall bind the successors, assigns,
receivers, trustees and representatives of the Guarantor and shall inure to the
benefit of the Holders of the Preferred Securities then outstanding. Except in

permitted under Article Eight of the Indenture, the Guarantor shall not assign
its obligations hereunder.

            SECTION 8.2. Amendments. Except with respect to any changes which do
not adversely affect the rights of Holders (in which case no consent of Holders
will be required), this Guarantee Agreement may only be amended with the prior
approval of the Holders of not less than a Majority in Liquidation Amount of the
Preferred Securities. The provisions of Article VI of the Trust Agreement
concerning meetings of Holders shall apply to the giving of such approval.

            SECTION 8.3. Notices. Any notice, request or other communication
required or permitted to be given hereunder shall be in writing, duly signed by
the party giving such notice, and delivered, telecopied or mailed by first class

                  otherwise required by the Delaware Business Trust Act or the
                  Trust Indenture Act, to execute on behalf of the Trust (either

                  Trustees) any documents that the Administrative Trustees have
                  the power to execute pursuant to this Trust Agreement; and

                           (x) the taking of any action incidental to the
                  foregoing as the Administrative Trustees may from time to time
                  determine is necessary or advisable to give effect to the
                  terms of this Trust Agreement for the benefit of the
                  Securityholders (without consideration of the effect of any

         power, duty and authority to act on behalf of the Trust with respect to
         the following matters:

                           (i)  the establishment and maintenance of the

                  Debentures into the Payment Account;

                           (iv)  the distribution of amounts owed to the
                  Securityholders in respect of the Trust Securities;

                  execution and filing of the certificate of
                  cancellation with the Secretary of State of the
                  State of Delaware;

                           (viii) after the occurrence of an Event of Default,
                  the taking of any action incidental to the foregoing as the
                  Property Trustee may from time to time determine is necessary
                  or advisable to protect and conserve the Trust Property for
                  the benefit of the Securityholders (without consideration of
                  the effect of any such action on any particular
                  Securityholder); and

                           (ix) subject to this Section 2.07(a)(B), the Property
                  Trustee shall have none of the duties of the Administrative
                  Trustees set forth in Section 2.07(a)(A).

                  (b) So long as this Trust Agreement remains in effect, the
Trust (or the Trustees acting on behalf of the Trust) shall not undertake any
business, activities or transaction except as expressly provided herein or
contemplated hereby. In particular, the Trustees shall not (i) acquire any
investments or engage in any activities not authorized by this Trust Agreement,
(ii) sell, assign, transfer, exchange, pledge, set-off or otherwise dispose of
any of the Trust Property or interests therein, including to Securityholders,
except as expressly provided herein, (iii) take any action that would cause the
Trust to be treated as an association taxable as a corporation for United States
Federal income tax purposes, (iv) incur any indebtedness for borrowed money or
(v) take or consent to any action that would result in the placement of a Lien
on any of the Trust Property. The Administrative Trustees shall defend all
claims and demands of all Persons at any time claiming any Lien on any of the
Trust Property adverse to the interest of the Trust or the Securityholders in
their capacity as Securityholders.

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

                           (i) to prepare for filing with the Commission a

         thereto;

<PAGE>



                           (ii) to determine the States in which to take
         appropriate action to qualify or register for sale all or part of the
         Preferred Securities and to do any and all such acts, other than
         actions which must be taken by or on behalf of the Trust, and advise
         the Trustees of actions they must take on behalf of the Trust, and
         prepare for execution and filing any documents to be executed and filed
         by the Trust or on behalf of the Trust, as the Depositor deems
         necessary or advisable in order to comply with the applicable laws of
         any such States;

                           (iii) to prepare for filing by the Trust an
         application to the New York Stock Exchange for listing upon notice of
         issuance of the Preferred Securities;

                           (iv) to prepare for filing by the Trust with the
         Commission a registration statement on Form 8-A relating to the
         registration of the Preferred Securities under Section 12(b) of the
         Securities Exchange Act of 1934, as amended, including any amendments
         thereto;

                           (v)  to negotiate the terms of, and execute and
         deliver, the Underwriting Agreement providing for the sale of
         the Preferred Securities; and

                           (vi)  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 Trust and to operate the Trust so that the Trust will not be deemed to be an
"investment company" required to be registered under the Investment Company Act
of 1940, as amended, or taxed as a corporation 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 so doing, the
Depositor and the Administrative Trustees are authorized to take any action, not
inconsistent with applicable law, the Certificate of Trust or this Trust
Agreement, that the Depositor or any of the Administrative Trustees determines
in its or his discretion to be necessary or desirable for such purposes,
provided that such action does not adversely affect the interests of the Holders
of the Preferred Securities. Any action not specifically assigned herein that
the Trustees may be permitted or required to do under this Trust Agreement may
be taken by majority vote of the Trustees.

            Section 2.08. Assets of the Trust. The assets of the Trust shall
consist of the Trust Property.

            Section 2.09. 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 for the benefit of the Securityholders in
accordance with this Trust Agreement.

                                 PAYMENT ACCOUNT

            Section 3.01. Payment Account. (a) On or prior to the Closing Date,
the Property Trustee shall establish the Payment Account. The Property Trustee
and any agent of the Property Trustee 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 Securityholders and for
distribution as herein provided, including (and subject to) any priority of
payments provided for herein.

                  (b) The Property Trustee shall deposit in the Payment Account,
promptly upon receipt, all payments of principal 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; REDEMPTIONS

            Section 4.01. Distributions. (a) Distributions on the Trust
Securities shall be cumulative, and will accumulate whether or not there are
funds of the Trust available for the payment of Distributions. Distributions
shall accrue from October 21, 1996, and, except in the event that SPS exercises
its right to extend the interest payment period for the Debentures pursuant to
Section 101 of the Supplemental Indenture, shall be payable quarterly in arrears
on March 1, June 1, September 1 and December 1 of each year, commencing on
December 1, 1996. If any date on which Distributions are 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 which is a Business Day
(and without any interest or other payment in respect of any such delay) except
that, if such Business Day is in the next succeeding calendar year, payment of
such distribution shall be made on the immediately preceding Business Day, in
each case, with the same force and effect as if made on such date (each date on
which distributions are payable in accordance with this Section 4.01(a), a
"Distribution Date").



                                      -17-

<PAGE>



                  (b) The Trust Securities represent beneficial interests in the
Trust, and, subject to Section 4.03 hereof, all Distributions will be made pro
rata on each of the Trust Securities; distributions payable as a preference on
the Preferred Securities shall be fixed at a rate of 7.85% per annum of the
Liquidation Amount of the Preferred Securities. The amount of Distributions
payable for any full quarterly period shall be computed on the basis of a
360-day year of twelve 30-day months and, for any period shorter than a full
monthly period, shall be computed on the basis of the actual number of days
elapsed in such period. If the interest payment period for the Debentures is
extended pursuant to Section 101 of the Supplemental Indenture, then the rate
per annum at which Distributions on the Trust Securities accumulate shall be
increased by an amount such that the aggregate amount of Distributions that
accumulate on all Trust Securities during any such extended interest payment
period is equal to the aggregate amount of interest (including interest payable
on unpaid interest at the percentage rate per annum set forth above, compounded
quarterly) that accrues during any such extended interest payment period on the
Debentures. The amount of Distributions payable for any period shall include the
Additional Amounts, if any.

                  (c) Distributions on the Trust Securities shall be made and
shall be deemed payable on each Distribution Date only to the extent that the
Trust has funds legally and immediately available in the Payment Account for the
payment of such Distributions.

                  (d) 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 on the relevant record date, which
shall be one Business Day prior to such Distribution Date; provided, however,
that in the event that the Preferred Securities do not remain in book-entry-only
form, the relevant record date shall be the date 15 days prior to the relevant
Distribution Date.

            Section 4.02. Redemptions. (a) On each Debenture Redemption Date,
the Trust will be required to redeem a Like Amount of Trust Securities at the
Redemption Price.

                  (b) If (i) (x) a Special Event shall occur and be continuing
and (y) within 45 days following the occurrence of such Special Event the
Trustees shall not have received from the Debenture Trustee a notice of
redemption of all of the Debentures on a Debenture Redemption Date (as specified
in such notice) which is to occur not later than 90 days following the
occurrence of such Special Event, or (ii) if the Trust is not or will not be
taxed as a grantor trust, but a Tax Event has not occurred, the Depositor may in
its sole discretion direct the Trustees to, and the Trustees shall if so
directed by the Depositor, dissolve the Trust and cause the Trust to distribute
to each Holder of Trust Securities, in


                                      -18-

<PAGE>



accordance with Section 9.04 and on a Liquidation Date which shall occur not
later than 90 days following the occurrence of such Special Event, a Like Amount
of Debentures in liquidation of the Trust; provided, however, that the Trustees
shall be required to follow the direction of the Depositor to dissolve the Trust
and distribute the Debentures to Holders of Trust Securities in accordance with
this Section 4.02(b) and Section 9.04 only if the Trust shall have received an
Opinion of Counsel experienced in such matters to the effect that the Holders of
Preferred Securities will not recognize any gain or loss for United States
Federal income tax purposes as a result of such distribution. The election of
the Depositor to cause the Trust to be dissolved shall be evidenced by a Board
Resolution. If the Trust is not dissolved pursuant to the preceding sentence and
the Trust Securities remain Outstanding, then Additional Interest Attributable
to Taxes (as defined in the Subordinated Indenture) will be payable on the
Debentures.

                  (c) Notice of redemption shall be given by the Property
Trustee by first-class mail, postage prepaid, mailed not less than 30 nor more
than 90 days prior to the Redemption Date to each Holder of Trust Securities to
be redeemed, at such Holder's address appearing in the Securities Register. All
notices of redemption shall identify the Trust Securities to be redeemed
(including CUSIP number) and shall state:

                  (i)  the Redemption Date;

                  (ii)  the Redemption Price;

                  (iii)  the place of payment where such Trust
         Securities are to be surrendered for payment of the
         Redemption Price; and

                  (iv) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Trust Security to be redeemed and
         that, if the monies required to effect such redemption have been duly
         deposited by SPS with the Property Trustee, interest thereon will cease
         to accrue on and after said date.

                  (d) 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 deemed payable on each
Redemption Date only to the extent that the Trust has funds immediately
available in the Payment Account for the payment of such Redemption Price.

                  (e) If the Property Trustee gives a notice of redemption in
respect of any Preferred Securities, then, by 12:00 noon, New York time, on the
Redemption Date, subject to Section 4.02(d), the Property Trustee shall, so long
as the Preferred Securities are in


                                      -19-

<PAGE>



book-entry-only form, irrevocably deposit with the Clearing Agency for the
Preferred Securities funds sufficient to pay the applicable Redemption Price
and, at the direction of the Depositor, shall give such Clearing Agency
irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof; provided if the Property Trustee does not do so, it will be
regarded as having revoked the notice of redemption. If the Preferred Securities
are no longer in book-entry-only form, the Property Trustee, subject to Section
4.02(d), shall irrevocably deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and shall give the Paying Agent irrevocable
instructions to pay the Redemption Price to the Holders thereof upon surrender
of their Preferred Securities Certificates. Notwithstanding the foregoing,
Distributions payable on or prior to the Redemption Date for 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 Securityholders holding Trust Securities so called for redemption
will cease, except the right of such Securityholders to receive the Redemption
Price, but without interest on such Redemption Price, 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 shall be made on the next succeeding day which is a
Business Day (and without any interest or other payment in respect of any such
delay) except that, if such Business Day is in the next succeeding calendar
year, payment of such Distribution shall 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 not paid either by the Trust or by the
Depositor pursuant to the Guarantee, such Trust Securities shall be considered
to remain outstanding and will continue to accrue, at the rate specified above,
from the Redemption Date originally established by the Trust for such Trust
Securities to the date such Redemption Price is actually paid, in which case the
actual payment date will be the date fixed for redemption for purposes of
calculating the Redemption Price.

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

                  (g) 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


                                      -20-

<PAGE>



allocated to the Common Securities and the Preferred Securities on a pro rata
basis based upon their respective aggregate Liquidation Amounts. The particular
Preferred Securities to be redeemed shall be selected not more than 90 days
prior to the Redemption Date by the Property Trustee from the Outstanding
Preferred Securities not previously called for redemption, by such method as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $25 or any integral multiple
thereof) of the aggregate Liquidation Amount of Preferred Securities of a
denomination larger than $25. The Property Trustee shall promptly notify the
Securities Registrar in writing of the Preferred Securities selected for
redemption and, in the case of any Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the aggregate Liquidation Amount of Preferred Securities which has been or is
to be redeemed.

            Section 4.03. Subordination of Common Securities. (a) Payment of
Distributions (including Additional Amounts, if applicable) on, and the
Redemption Price of, the Trust Securities, as applicable, shall be made pro rata
based on the aggregate Liquidation Amount of the Trust Securities; provided,
however, that if on any Distribution Date or Redemption Date a Debenture Event
of Default shall have occurred and be continuing, no payment of any Distribution
(including Additional Amounts, if applicable) on, or Redemption Price of, any
Common Security, and no other payment on account of the redemption, liquidation
or other acquisition of Common Securities, shall be made unless payment in full
in cash of all accumulated and unpaid Distributions (including Additional
Amounts, if applicable) payable as a preference on all Outstanding Preferred
Securities for all distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities called for redemption, shall have
been made or provided for, and all funds available to the Property Trustee shall
first be applied to the payment in full in cash of all Distributions (including
Additional Amounts, if applicable) on, or the Redemption Price of, Preferred
Securities then due and payable.

                  (b) In the case of the occurrence of any Debenture Event of
Default, the Holder of Common Securities will be deemed to have waived any right
to act with respect to any Event of Default until the effect of all such Events
of Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Events of Default under this Trust
Agreement with respect to the Preferred Securities have been so cured, waived or
otherwise eliminated, the Property Trustee shall act in accordance with Article
VIII hereof and solely on behalf of


                                      -21-

<PAGE>



the Holders of the Preferred Securities and not the Holder of the Common
Securities. In such event, only the Holders of the Preferred Securities will
have the right to direct the Property Trustee to act on their behalf.

            Section 4.04. Payment Procedures. Payments in respect of the
Preferred Securities shall be made by check mailed to the address of the Person
entitled thereto as such address shall appear on the Securities Register or, if
the Preferred Securities are held by a Clearing Agency, payments shall be made
by wire transfer to the Clearing Agency, which shall credit the relevant
Persons' accounts at such Clearing Agency on the applicable Distribution Dates.
Payments in respect of the Common Securities shall be made in such manner as
shall be mutually agreed between the Property Trustee and the Common
Securityholder.

            Section 4.05. 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
(including, without limitation, Form 8281 which must be filed by an issuer of an
original issue discount security) and reports required to be filed by or in
respect of the Trust. In this regard, the Administrative Trustees shall prepare
and file (or cause to be prepared or filed) the Internal Revenue Service forms
required to be filed in respect of the Trust in each taxable year of the Trust.
The Administrative Trustees shall provide the Depositor and the Property Trustee
with a copy of all such returns, reports and schedules promptly after such
filing or furnishing. The Trustees shall comply with United States Federal
withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

            Section 4.06. Payment of Taxes, Duties, Etc. of the Trust. Upon
receipt under the Debentures of Additional Interest Attributable to Taxes (as
defined in the Subordinated Indenture), the Property Trustee shall distribute to
the Administrative Trustees an amount requested by them and they shall promptly
pay any taxes, duties, assessments or governmental charges of whatsoever nature
(other than withholding taxes) imposed on the Trust by the United States or any
other taxing authority.

owner of the Trust.

            Section 5.02. The Trust Securities Certificates. Initial Holders
shall purchase Preferred Securities in minimum denominations of $25 (based on
Liquidation Amount) and integral multiples of $25 in excess thereof, and the
Common Securities Certificates shall be issued in denominations of $25 (based on
Liquidation Amount) and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by the facsimile or manual
signature of at least one Administrative Trustee. Trust Securities Certificates
bearing the manual signatures of individuals who were, at the time when such
signatures shall have been affixed, authorized to sign on behalf of the Trust,
shall be validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Section 5.04.

            Section 5.03. 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 2.04
and 2.05, to be executed on behalf of the Trust and delivered to or upon the
written order of the Depositor signed by its chairman of the board, its
president, any executive vice president, any senior vice president, any vice
president, the treasurer or secretary without further corporate action by the
Depositor, in authorized denominations.

            Section 5.04. Registration of Transfer and Exchange of Preferred
Securities Certificates. The Securities Registrar shall keep or cause to be kept
a Securities Register in which, subject to such reasonable regulations as it may
prescribe, the Securities Registrar shall provide for the registration of Trust
Securities Certificates and registration of transfers and exchanges of Trust
Securities Certificates as herein provided. The Bank shall be the initial
Securities Registrar. The provisions of Sections 8.01, 8.03 and 8.06 shall apply
to the Bank in its role as Securities Registrar.

            Upon surrender for the registration of the transfer of any Trust
Securities Certificate, the Administrative Trustees or any one of them shall
execute and deliver, in the name of the designated transferee or transferees,
one or more new Trust Securities Certificates in authorized denominations of a
like aggregate Liquidation Amount dated the date of execution by such
Administrative Trustee or Trustees. The Securities Registrar shall not be
required to register the transfer of any Trust Securities that have been called
for redemption. At the option of a Holder,


                                      -23-

<PAGE>



Trust Securities Certificates may be exchanged for other Trust Securities
Certificates in authorized denominations of the same class and of a like
aggregate Liquidation Amount upon surrender of the Trust Securities Certificates
to be exchanged.

            Every Trust Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer, in form satisfactory to the Administrative Trustees and
the Securities Registrar, duly executed by the Holder or his or her attorney.
Each Trust Securities Certificate surrendered for registration of a transfer or
exchange shall be canceled and subsequently disposed of by the Administrative
Trustees.

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

            Section 5.05. Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates. If (a) any mutilated Trust Securities Certificate shall be
surrendered to the Securities Registrar, or if the Securities Registrar shall
receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Securities Certificate, and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees or any one of them on behalf of the Trust
shall execute and make available for delivery, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Trust Securities Certificate, a new
Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust Securities Certificate under this
Section, the Administrative Trustees or the Securities Registrar may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection therewith. Any duplicate Trust Securities
Certificate issued pursuant to this Section shall constitute conclusive evidence
of a beneficial interest in the Trust, as if originally issued, whether or not
the lost, stolen or destroyed Trust Securities Certificate shall be found at any
time.

            Section 5.06. Persons Deemed Securityholders. Prior to due
presentation of a Trust Securities Certificate for registration of transfer, the
Trustees or the Securities Registrar shall treat the Person in whose name any
Trust Securities Certificate shall be registered in the Securities Register as
the owner of such Trust Securities Certificate for the purpose of receiving
distributions and for all other purposes whatsoever, and neither the Trustees
nor


                                      -24-

<PAGE>



the Securities Registrar shall be bound by any notice to the
contrary.

            Section 5.07. Access to List of Securityholders' Names and
Addresses. In addition to, and not by way of limitation of, the Depositor's
obligations under Section 312(a) of the Trust Indenture Act, the Depositor shall
furnish or cause to be furnished to the Property Trustee semi-annually, not
later than February 15 and August 15 of each year, a list in such form as the
Property Trustee may reasonably require, of the names and addresses of all
Owners of Preferred Securities. The Securities Registrar shall furnish or cause
to be furnished (x) to the Depositor, within 15 days after receipt by the
Securities Registrar of a request therefor from the Depositor in writing and (y)
to the Property Trustee, promptly after receipt by the Securities Registrar of a
request therefor from the Property Trustee , a list, in such form as the
Depositor or the Property Trustee (as applicable) may reasonably require, of the
names and addresses of the Securityholders as of the most recent record date. In
addition to, and not by way of limitation of, the provisions of Section 312(b)
of the Trust Indenture Act, if one or more Holders of Trust Securities
Certificates evidencing not less than 25% of the Liquidation Amount of the
outstanding Preferred Securities apply in writing to the Securities Registrar,
and such application states that the applicants desire to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under
the Trust Securities Certificates, and such application is accompanied by a copy
of the communication that such applicants propose to transmit, then the
Securities Registrar shall, within five Business Days after the receipt of such
application, afford such applicants access during normal business hours to the
current list of Securityholders. Each Holder, by receiving and holding a Trust
Securities Certificate, shall be deemed to have agreed not to hold either the
Depositor or the Securities Registrar accountable by reason of the disclosure of
its name and address, regardless of the source from which such information was
derived.

            Section 5.08. Appointment of Paying Agent. The Paying Agent shall
make distributions to Securityholders from the Payment Account and shall report
the amounts of such distributions to the Property Trustee and the Administrative
Trustees. The Paying Agent shall have the revocable power to withdraw funds from
the Payment Account for the purpose of making the distributions referred to
above. The Administrative Trustees may revoke such power and remove the Paying
Agent if such Trustees determine in their sole discretion that the Paying Agent
shall have failed to perform its obligations under this Agreement in any
material respect. The Paying Agent shall initially be the Bank, and the Paying
Agent may choose any co-paying agent that is acceptable to the Administrative
Trustees, the Property Trustee and the Depositor. Any Person acting as a Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Administrative Trustees,


                                      -25-

<PAGE>



the Property Trustee and the Depositor. In the event that the Bank shall no
longer be the Paying Agent or a successor Paying Agent shall resign or its
authority to act be revoked, the Administrative Trustees shall appoint a
successor that is acceptable to the Property Trustee and the Depositor to act as
Paying Agent (which shall be a bank, trust company or the Depositor). The
Administrative Trustees shall cause such successor Paying Agent or any co-paying
agent appointed by the Paying Agent to execute and deliver to the Trustees an
instrument in which such successor Paying Agent or additional Paying Agent shall
agree with the Trustees that as Paying Agent, such successor Paying Agent or
additional Paying Agent will hold all sums, if any, held by it for payment to
the Securityholders in trust for the benefit of the Securityholders entitled
thereto until such sums shall be paid to such Securityholders. The Paying Agent
shall return all unclaimed funds to the Property Trustee and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to
the Property Trustee. The provisions of Sections 8.01, 8.03 and 8.06 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.

            Any Paying Agent shall hold in trust for the benefit of the
Preferred Securityholders all sums held by such Paying Agent for payment on the
Preferred Securities, and shall give the Property Trustee notice of any default
hereunder by either the Trust or the Depositor.

            Section 5.09. Book-Entry Preferred Securities Certificates; Common
Securities Certificate. (a) The Preferred Securities Certificates, upon original
issuance, will be issued in the form of a typewritten Preferred Securities
Certificate or Certificates representing Book-Entry Preferred Securities
Certificates to be delivered to The Depository Trust Company, the initial
Clearing Agency, or to a custodian designated by it, by, or on behalf of, the
Trust. Such Preferred Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no Owner will receive a definitive Preferred
Securities Certificate representing such Owner's interest in such Preferred
Securities, except as provided in Section 5.11. Unless and until Definitive
Preferred Securities Certificates have been issued to Owners pursuant to Section
5.11:

                  (i)  the provisions of this Section 5.09(a) shall be
         in full force and effect;

                  (ii) the Securities Registrar, the Paying Agent and the
         Trustees shall be entitled to deal with the Clearing Agency for all
         purposes of this Trust Agreement relating


                                      -26-

<PAGE>



         to the Book-Entry Preferred Securities Certificates (including the
         payment of principal of and interest on the Book-Entry Preferred
         Securities and the giving of instructions or directions to Owners of
         Book-Entry Preferred Securities) as the sole Holder of Book-Entry
         Preferred Securities, and shall have no obligations to the Owners
         thereof;

                  (iii) to the extent that the provisions of this Section 5.09
         conflict with any other provisions of this Trust Agreement, the
         provisions of this Section 5.09 shall control;

                  (iv) the rights of the Owners of the Book-Entry Preferred
         Securities Certificates shall be exercised only through the Clearing
         Agency and shall be limited to those established by law and agreements
         between such Owners and the Clearing Agency and/or the Clearing Agency
         Participants. Pursuant to the Letter of Representations, unless and
         until Definitive Preferred Securities Certificates are issued pursuant
         to Section 5.11, the initial Clearing Agency will make book-entry
         transfers among the Clearing Agency Participants and receive and
         transmit payments on the Preferred Securities to such Clearing Agency
         Participants; and

                  (v) whenever this Trust Agreement requires or permits actions
         to be taken based upon the instructions or directions of Holders of
         Trust Certificates evidencing a specified percentage of the aggregate
         Liquidation Amount, the Clearing Agency shall be deemed to represent
         such percentage only to the extent that it has received instructions to
         such effect from Owners and/or Clearing Agency Participants owning or
         representing, respectively, such required percentage of the beneficial
         interest in the applicable class of Trust Certificates and has
         delivered such instructions to the Administrative Trustees.

                  (b) A single Common Securities Certificate representing the
Common Securities shall be issued to the Depositor in the form of a definitive
Common Securities Certificate. In the event that the Depositor shall transfer
any of its Common Securities, additional Common Securities Certificates, in
definitive form, may be issued if required.

            Section 5.10. Notices to Clearing Agency. To the extent a notice or
other communication to the Owners is required under this Trust Agreement, unless
and until Definitive Preferred Securities Certificates shall have been issued to
Owners pursuant to Section 5.11, the Trustees shall give all such notices and


                                      -27-

<PAGE>



communications specified herein to be given to the Clearing Agency, and shall
have no obligations to the Owners.

            Section 5.11. Definitive Preferred Securities Certificates. If (i)
the Depositor advises the Trustees in writing that the Clearing Agency is no
longer willing or able properly to discharge its responsibilities with respect
to the Preferred Securities Certificates, and the Depositor is unable to locate
a qualified successor, (ii) the Depositor at its option advises the Trustees in
writing that it elects to terminate the book-entry system through the Clearing
Agency or (iii) after the occurrence of an Event of Default, Owners of Preferred
Securities Certificates representing beneficial interests aggregating at least a
majority of the Liquidation Amount advise the Clearing Agency in writing that
the continuation of a book-entry system through the Clearing Agency is no longer
in the best interest of the Owners of Preferred Securities Certificates, then
the Clearing Agency shall notify all Owners of Preferred Securities Certificates
and the Trustees of the occurrence of any such event and of the availability of
the Definitive Preferred Securities Certificates to Owners of such class or
classes, as applicable, requesting the same. Upon surrender to the
Administrative Trustees by the Clearing Agency of the typewritten Preferred
Securities Certificate or Certificates representing the Book-Entry Preferred
Securities Certificates, accompanied by registration instructions, the
Administrative Trustees, or any one of them, shall execute the Definitive
Preferred Securities Certificates in accordance with the instructions of the
Clearing Agency. Neither the Securities Registrar nor the Trustees shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be protected in relying on, such instructions. Upon the issuance
of Definitive Preferred Securities Certificates, the Trustees shall recognize
the Holders of the Definitive Preferred Securities Certificates as Security-
holders. The Definitive Preferred Securities Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Administrative Trustees, as evidenced by the execution thereof
by the Administrative Trustees or any one of them.

            Section 5.12. Rights of Securityholders. The legal title to the
Trust Property is vested exclusively in the Property Trustee (in its capacity as
such) in accordance with Section 2.09. The Securityholders shall not have any
right or title therein other than the beneficial interest in the Trust conferred
by their Trust Securities, and they shall have no right to call for any
partition or division of property, profits or rights of the Trust except as
described below. The Trust Securities shall be personal property giving only the
rights specifically set forth therein and in this Trust Agreement. The Trust
Securities shall have no preemptive rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Trust Securities,


                                      -28-

<PAGE>



in their capacities as such, shall, except as otherwise set forth herein, 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.

            The right of any Holder of Trust Securities to receive payment of
Distributions on the Trust Securities in accordance with this Trust Agreement
and the terms of the Trust Securities on or after the respective payment dates
thereof, or to institute suit for the enforcement of any such payments on or
after such payment dates, shall not be impaired without the consent of each such
Holder.


                                   ARTICLE VI

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

            Section 6.01. Limitations on Voting Rights. (a) Except as provided
in this Section, in Sections 8.10 and 10.02 hereof, and in the Subordinated
Indenture, and as otherwise required by law, no Holder of Preferred Securities
shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

            (b) So long as any Debentures are held by the Property Trustee on
behalf of the 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 executing any trust or power conferred on the Debenture Trustee with
respect to such Debentures, (ii) waive any past default which is waivable under
Section 513 of the Subordinated 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
Subordinated 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 Outstanding Trust Securities; provided,
however, that where a consent under the Subordinated 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 Trust Securities. The Property Trustee shall not revoke any action previously
authorized or approved by a vote of the Trust Securities, except pursuant to a
subsequent vote of the Outstanding Trust Securities. The Property Trustee shall
notify all Holders of the Trust Securities of any notice of default received
from the


                                      -29-

<PAGE>



Debenture Trustee with respect to the Debentures. In addition to obtaining the
foregoing approvals of the Holders of the Outstanding Trust Securities, prior to
taking any of the foregoing actions, the Property Trustee shall, at the expense
of the Depositor, obtain an Opinion of Counsel experienced in such matters to
the effect that the Trust will not be classified as an association taxable as a
corporation for United States Federal income tax purposes on account of such
action.

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

            Section 6.02. Notice of Meetings. Notice of all meetings of the
Preferred Securityholders, stating the time, place and purpose of the meeting,
shall be given by the Administrative Trustees pursuant to Section 10.07 to each
Trust Securityholder of record, at his or her 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.

            Any and all notices to which any Trust Securityholder hereunder may
be entitled and any and all communications shall be deemed duly served or given
if mailed, postage prepaid, addressed to any Preferred Securityholder of record
at his last known address as recorded on the Securities Register.

            Section 6.03. Meetings of Trust Securityholders. No annual meeting
of Securityholders is required to be held. The Administrative Trustees, however,
shall call a meeting of Security- holders to vote on any matter upon the written
request of Securityholders of record holding 25% (based upon aggregate
Liquidation Amount) of the Outstanding Trust Securities, and the Administrative
Trustees or the Property Trustee may, at any time in their discretion, call a
meeting of Securityholders to vote on any matters as to which Securityholders
are entitled to vote.



                                      -30-

<PAGE>



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

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

            Section 6.04. Voting Rights. Securityholders shall be entitled to
one vote for each $25 of Liquidation Amount represented by their Trust
Securities in respect of any matter as to which such Securityholders are
entitled to vote. Securityholders' voting rights shall be as provided by Section
316 of the Trust Indenture Act.

            Section 6.05. Proxies, Etc. At any meeting of Securityholders, any
Securityholder entitled to vote thereat may vote by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken. Pursuant to a request by the Property
Trustee, proxies may be solicited in the name of the Property Trustee or one or
more officers of the Property Trustee. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities. A proxy purporting to be executed by or on behalf of a
Securityholder shall be deemed valid unless challenged at or prior to its
exercise, and the burden of proving invalidity shall rest on the challenger. No
proxy shall be valid later than thirty-six (36) full calendar months after its
date of execution (or such shorter period as may be provided therein).

            Section 6.06. Securityholder Action by Written Consent. Any action
which may be taken by Securityholders at a meeting may be taken without a
meeting if Securityholders holding more than a majority of all Outstanding Trust
Securities (based upon aggregate Liquidation Amount) entitled to vote in respect
of such action (or such larger proportion thereof as shall be required by any
express provision of this Trust Agreement) shall consent to the action in
writing.



                                      -31-

<PAGE>



            Section 6.07. Record Date for Voting and Other Purposes. For the
purposes of determining the Securityholders who are entitled to notice of and to
vote at any meeting or by written consent, or to participate in any distribution
on the Trust Securities in respect of which a record date is not otherwise
provided for in this Trust Agreement, or for the purpose of any other action,
the Administrative Trustees may, in the circumstances permitted under the Trust
Indenture Act, from time to time fix a date, not more than 90 days prior to the
date of any meeting of Securityholders, the payment of any distribution or other
action, as the case may be, as a record date for the determination of the
identity of the Securityholders of record for such purposes. If not set by the
Administrative Trustees prior to the first solicitation of a Securityholder made
by any Person in respect of any such action, or, in the case of any such vote,
prior to such vote, the record date for any such action or vote shall be the
30th day (or, if later, the date of the most recent list of Holders required to
be provided pursuant to Section 5.07) prior to such first solicitation or vote,
as the case may be. With regard to any record date, only the Holders on such
date (or their duly designated proxies) shall be entitled to give or take, or
vote on, the relevant action.

            Section 6.08. Acts of Securityholders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Trust Agreement to be given, made or taken by Securityholders
may be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Securityholders in person or by an agent duly
appointed in writing; and, except as otherwise expressly provided herein, such
action shall become effective when such instrument or instruments are delivered
to an Administrative Trustee. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Securityholders 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
8.01) conclusive in favor of the Trustees, if made in the manner provided in
this Section.

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


                                      -32-

<PAGE>




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

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

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

            Section 6.09. Inspection of Records. Subject to Section 5.07
concerning access to the list of Securityholders, upon reasonable notice to the
Administrative Trustees and the Property Trustee, the other records of the Trust
shall be open to inspection by Securityholders during normal business hours for
any purpose reasonably related to such Securityholder's interest as a
Securityholder.

                  (c) this Trust Agreement has been duly authorized, executed
         and delivered by the Bank and constitutes the valid and legally binding
         agreement of the Bank enforceable against it in accordance with its

         reorganization, moratorium and similar laws of general applicability
         relating to or affecting creditors' rights and to general equity
         principles;

                  (d) the execution, delivery and performance by the Bank of
         this Trust Agreement have been duly authorized by all necessary

         performance will not (i) violate the Bank's Charter or By-laws, (ii)
         violate any provision of, or constitute, with or without notice or
         lapse of time, a default under, or result in the creation or imposition
         of, any Lien on any properties included in the Trust Property pursuant
         to the provisions of, any indenture, mortgage, credit agreement,
         license or other agreement or instrument to which the Bank is a party
         or by which it is bound, or (iii) violate any law, governmental rule or
         regulation of the United States or the State of Delaware governing the
         banking or trust powers of the Bank or any order, judgment or decree
         applicable to the Bank;

                  (e) neither the authorization, execution or delivery by the
         Bank of this Trust Agreement nor the consummation of any of the
         transactions by the Bank contemplated herein or therein requires the
         consent or approval of, the giving of notice to, the registration with
         or the taking of any other action with respect to, any governmental
         authority or agency under any existing Federal law governing the
         banking or trust powers of the Bank or under the laws of the State of
         Delaware; and

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


                                  ARTICLE VIII

                                  THE TRUSTEES

            Section 8.01. Certain Duties and Responsibilities. (a) The duties
and responsibilities of the Trustees shall be as provided by this Trust
Agreement and, in the case of the Property Trustee, by the Trust Indenture Act.
The Trustees shall have all the privileges, rights and immunities provided by
the Delaware


                                      -34-

Business Trust Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require any of the Trustees to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it 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. To the
extent that, at law or in equity, a Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or to the Securityholders,
such Trustee shall not be liable to the Trust or to any Securityholder for such
Trustee's good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of the Trustees otherwise existing at law or in equity, are
agreed by the Depositor and the Securityholders to replace such other duties and
liabilities of the Trustees. Whether or not therein expressly so provided, every
provision of this Trust Agreement relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section and, in the case of the Property Trustee, to the
provisions of the Trust Indenture Act.

            (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the income and proceeds
from the Trust Property. Each Securityholder, by its acceptance of a Trust
Security, agrees that it will look solely to the income and proceeds from the
Trust Property to the extent legally available for distribution to it as herein
provided and that the Trustees are not personally liable to it for any amount
distributable in respect of any Trust Security or for any other liability in
respect of any Trust Security. This Section 8.01(b) does not limit the liability
of the Trustees expressly set forth elsewhere in this Trust Agreement or, in the
case of the Property Trustee, in the Trust Indenture Act.

            (c) 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 and no implied covenants shall be read into this Trust
Agreement against the Property Trustee. In case an Event of Default has occurred
(that has not been cured or waived), 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 their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of his or her own affairs.

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


                                      -35-

<PAGE>




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

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

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

                 (iv) the Property Trustee shall not be liable for any interest
                      on any money received by it except as it may otherwise
                      agree with the Depositor. 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 3.01 and except
                      to the extent otherwise required by law;

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

                 (vi) the Property Trustee shall have no responsibility for the
                      genuineness, value or


                                      -36-

                      sufficiency of the Debentures, or for the payment of any
                      taxes assessed or levied thereon.

            Section 8.02. Notice of Defaults. Within five Business Days after
the occurrence of any Event of Default actually known to the Property Trustee,
the Property Trustee shall transmit, in the manner and to the extent provided in
Section 10.09, notice of such Event of Default to the Securityholders, the
Administrative Trustees and the Depositor, unless such default shall have been
cured or waived. For the purpose of this Section, the term "default" means any
event which is, or after notice or lapse of time or both would become, an Event
of Default.

            Section 8.03. Certain Rights of the Property Trustee. Subject to the
provisions of Section 8.01 and except as provided by law:

                  (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 or other paper or document believed by it to be
         genuine and to have been signed or presented by the proper party or
         parties;

                  (b) if (i) in performing its duties under this Trust Agreement
         the Property Trustee is required to decide between alternative courses
         of action or (ii) in construing any of the provisions in this Trust
         Agreement the Property Trustee finds the same ambiguous or inconsistent
         with any other provisions contained herein or (iii) the Property
         Trustee is unsure of the application of any provision of this Trust
         Agreement, then, except as to any matter as to which the Preferred
         Securityholders are entitled to vote under the terms of this Trust
         Agreement, the Property Trustee shall deliver a notice to the Depositor
         requesting written instructions of the Depositor as to the course of
         action to be taken. 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


                                      -37-

<PAGE>



         it shall deem advisable and in the best interests of the
         Securityholders, in which event the Property Trustee shall have no
         liability except for its own bad faith, negligence or willful
         misconduct;

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

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

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

                  (f) the Property Trustee may consult with counsel and the
         written 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; the Property
         Trustee shall have the right at any time to seek instructions
         concerning the administration of this Trust Agreement from any court of
         competent jurisdiction;

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

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


                                      -38-

<PAGE>



         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 or recklessness 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 of the Trust Securities which instructions may only be given by
         the Holders of the same proportion in Liquidation Amount of the Trust
         Securities as would be entitled to direct the Property Trustee under
         the 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.

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

                  Section 8.04. 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 Trust, and the Trustees do
not assume any responsibility for their correctness. The Trustees shall not be
accountable for the use or application by the Trust of the proceeds of the Trust
Securities, provided that such use or application is in accordance with Section
2.05.

            Section. 8.05. May Hold Securities. Except as provided in the
definition of the term "Outstanding" in Article I, any Trustee or any other
agent of any Trustee or the Trust, in its individual or any other capacity, may
become the owner or pledgee of Trust Securities and may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

            Section 8.06. Compensation; Fees; Indemnity. The Depositor and the
Trust each agrees:

                  (1) to pay to the Trustees from time to time such compensation
         as the Depositor and the Trustees shall from time to time agree in
         writing for all services rendered by the Trustees hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

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

                  (3) to indemnify each of the Trustees or any predecessor
         Trustee for, and to hold the Trustees harmless against, any and all
         loss, damage, claims, liability, penalty or expense, including taxes,
         other than taxes based on the income of the Trustee or withholding
         taxes imposed with respect to payments on the Trust Securities,
         incurred without negligence or bad faith on its part, arising out of or
         in connection with the acceptance or administration of this Trust
         Agreement, including the costs and expenses of defending itself against
         any claim or liability in connection with the exercise or performance
         of any of its powers or duties hereunder. The provisions of this
         Section 8.06 shall survive the termination of this Trust Agreement, and
         to secure the same, the Property Trustee shall have a lien against the
         Trust Property which lien shall be prior to the claims of the
         Securityholders.

            Section 8.07. Corporate Property Trustee Required; Eligibility of
Trustees. (a) There shall at all times be a Property Trustee, qualified as
provided in Section 310(a) of the Trust Indenture Act, hereunder with respect to
the Trust Securities. The Property Trustee shall be a Person that has (a) a
combined capital and surplus of at least $50,000,000 and (b) an


                                      -40-

<PAGE>



unsecured or deposit rating of at least investment grade by each of Standard &
Poor's Corporation and Moody's Investors Services, Inc. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

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

            Section 8.08. Conflicting Interests. None of the Trust, SPS or any
Person directly or indirectly controlling, controlled by or under common control
with either the Trust or SPS may serve as Property Trustee hereunder. If the
Property Trustee has or shall acquire a conflicting interest within the meaning
of the Trust Indenture Act, the Property Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Trust Agreement.

            Section 8.09. Co-Trustees and Separate Trustees. 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,
the Depositor and the Administrative Trustees, by agreed action of the majority
of such Administrative Trustees, shall have power to appoint, and upon the
written request of the Administrative Trustees, the Depositor shall for such
purpose join with the Administrative Trustees in the execution, delivery, and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Property Trustee either to act as
co-trustee, jointly with the Property Trustee, of all or any part of such Trust
Property, or to act as separate trustee of any such property, in accordance with
Section 310(a) of the Trust Indenture Act, in either case with such powers as
may be provided in the instrument of appointment, and to vest in such Person or
Persons in the capacity aforesaid, any property, title, right or power deemed
necessary or desirable, subject to the other provisions of this Section. If the
Depositor does not join in such appointment within 15 days after the receipt by
it of a request so to do, or in case a Debenture Event of Default has occurred
and is continuing, the Administrative Trustees and the Property Trustee,
respectively,


                                      -41-

<PAGE>



alone shall have power to make such appointment. Any co-trustee or separate
trustee appointed pursuant to this Section shall satisfy the requirements of
Section 8.07.

            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:

                  (1) The Trust Securities shall be executed and delivered, and
         all rights, powers, duties, and obligations hereunder in respect of the
         custody of securities, cash and other personal property held by, or
         required to be deposited or pledged with, the Trustees specified
         hereunder, shall be exercised, solely by such Trustees.

                  (2) 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.

                  (3) The Property Trustee at any time, by an instrument in
         writing executed by it, with the written concurrence of the Depositor,
         may accept the resignation of or remove any co-trustee or separate
         trustee appointed under this Section, and, in case an Event of Default
         under the Subordinated Indenture 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


                                      -42-

<PAGE>



         any co-trustee or separate trustee so resigned or removed may be
         appointed in the manner provided in this Section.

                  (4) 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.

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

                  (6) Any Act of Holders delivered to the Property Trustee shall
         be deemed to have been delivered to each such co-trustee and separate
         trustee. Upon receipt of such Act of Holders, the Property Trustee
         shall promptly deliver a copy thereof to each such co-trustee and
         separate trustee.

            Section 8.10. Resignation and Removal; Appointment of Successor. No
resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Relevant Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Relevant
Trustee in accordance with the applicable requirements of Section 8.11.

            The Relevant Trustee may resign at any time with respect to the
Trust Securities by giving written notice thereof to the Securityholders. If the
instrument of acceptance by a successor Relevant Trustee required by Section
8.11 shall not have been delivered to the Relevant Trustee within 30 days after
the giving of such notice of resignation, the resigning Relevant Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Relevant Trustee with respect to the Trust Securities.

            Unless an Event of Default shall have occurred and be continuing,
the Relevant Trustee may be removed at any time by the Depositor. If an Event of
Default shall have occurred and be continuing, the Relevant Trustee may be
removed at such time by Act of the Securityholders of a majority in aggregate
Liquidation Amount of the Trust Securities Certificates then Outstanding,
delivered to the Relevant Trustee (in its individual capacity and on behalf of
the Trust). In the event that any Securityholder is deemed to have waived the
right to act to remove the Relevant Trustee, then for the purpose of determining
whether a majority in aggregate Liquidation Amount of Trust Security
Certificates have acted to remove the Relevant Trustee, the Trust Securities of
such Securityholders shall be treated as if they are not Outstanding.

            If the Relevant Trustee shall resign, be removed or become incapable
of continuing to act as Relevant Trustee at a time when no Event of Default
shall have occurred and be continuing, the Depositor, by delivering notice to
the retiring Relevant Trustee,


                                      -43-

<PAGE>



shall promptly appoint a successor Relevant Trustee or Trustees with respect to
the Trust Securities and the Trust, and the retiring Relevant Trustee shall
comply with the applicable requirements of Section 8.11. If the Relevant Trustee
shall resign, be removed or become incapable of continuing to act as the
Relevant Trustee at a time when an Event of Default shall have occurred and be
continuing, the Securityholders, by Act of the Securityholders of a majority in
Liquidation Amount of the Trust Securities then Outstanding delivered to the
retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee
or Trustees with respect to the Trust Securities and the Trust, and the Relevant
Trustee shall comply with the applicable requirements of Section 8.11. In the
event that any Securityholder is deemed to have waived the right to appoint a
successor Relevant Trustee or Trustees with respect to the Trust Securities and
the Trust, then for the purpose of determining whether a majority in aggregate
Liquidation Amount of the Trust Securities then Outstanding have acted to
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, the Trust Securities of such Securityholder shall be
treated as if they are not Outstanding. If no successor Relevant Trustee with
respect to the Trust Securities shall have been so appointed by the Depositor or
the Trust Securityholders and have accepted such appointment in the manner
required by Section 8.11, any Securityholder who has been a Securityholder of
Trust Securities for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee with respect to the Trust
Securities.

            The retiring Relevant Trustee shall give notice of each resignation
and each removal of such Relevant Trustee and each appointment of a successor
Relevant Trustee with respect to the Trust Securities and the Trust to all
Securityholders in the manner provided in Section 10.09 and to the Depositor.
Each notice shall include the name of the successor Relevant Trustee and the
address of its Corporate Trust Office.

            Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Property Trustee who is
a natural person dies or becomes incompetent or incapacitated, the vacancy
created by such death, incompetence or incapacity may be filled by (i) the
unanimous act of remaining Administrative Trustees if there are at least two of
them or (ii) otherwise by the Depositor (with the successor in each case being
an individual who satisfies the eligibility requirement for Administrative
Trustees set forth in Section 8.07). Additionally, notwithstanding the foregoing
or any other provision of this Trust Agreement, in the event the Depositor
believes that any Administrative Trustee has become incompetent or
incapacitated, the Depositor, by notice to the remaining Trustees, may terminate
the status of such Person as an Administrative Trustee (in which


                                      -44-

<PAGE>



case the vacancy so created will be filled in accordance with the
preceding sentence).

            Section 8.11. Acceptance of Appointment by Successor. In case of the
appointment hereunder of a successor Relevant Trustee with respect to all Trust
Securities and the Trust, every such successor Relevant Trustee so appointed
shall execute, acknowledge and deliver to the Trust and to the retiring Relevant
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Relevant Trustee shall become effective, and 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 the request of the Depositor or the successor Relevant
Trustee, such retiring Relevant Trustee shall, upon payment of charges due to
such retiring Relevant Trustee, execute and deliver an instrument transferring
to such successor Relevant Trustee all the rights, powers and trusts of the
retiring Relevant Trustee and shall duly assign, transfer and deliver to such
successor Relevant Trustee all property and money held by such retiring Relevant
Trustee hereunder.

            In case of the appointment hereunder of a successor Relevant Trustee
with respect to the Trust Securities and the Trust, the retiring Relevant
Trustee and each successor Relevant Trustee with respect to the Trust Securities
shall execute and deliver an amendment hereto wherein each successor Relevant
Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Relevant Trustee all the rights, powers, trusts and
duties of the retiring Relevant Trustee with respect to the Trust Securities and
the Trust and (2) shall add to or change any of the provisions of this Trust
Agreement as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Relevant Trustee, it being understood
that nothing herein or in such amendment shall constitute such Relevant Trustees
co-trustees of the same trust and that each such Relevant Trustee shall be
trustee of a trust or trusts hereunder separate and apart from any trust or
trusts hereunder administered by any other such Relevant Trustee, and upon the
execution and delivery of such amendment the resignation or removal of the
retiring Relevant Trustee shall become effective to the extent provided therein
and each such successor Relevant Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Relevant Trustee with respect to the Trust Securities and the
Trust; but, on request of the Trust or any successor Relevant Trustee, such
retiring Relevant Trustee shall duly assign, transfer and deliver to such
successor Relevant Trustee all Trust Property, all proceeds thereof and money
held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.


                                      -45-

<PAGE>




            Upon request of any such successor Relevant Trustee, the
Administrative Trustees on behalf of the Trust shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Relevant Trustee all such rights, powers and trusts referred to in
this Section 8.11.

            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 corporation into which the Property Trustee or any Administrative
Trustee which is not a natural person may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which such Relevant Trustee shall be a party, shall be the
successor of such Relevant Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article VIII, 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
Trust. If and when the Property Trustee shall be or become a creditor of the
Depositor or the Trust (or any other obligor upon the Debentures or the Trust
Securities), the Property Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Depositor or
the Trust (or any such other obligor).

            Section 8.14. Reports by the Property Trustee. (a) Within 60 days
after December 31 of each year commencing with December 31, 1996, the Property
Trustee shall transmit by mail to all Securityholders, as their names and
addresses appear in the Securities Register, and to the Depositor, a brief
report dated as of such December 31 with respect to:

                  (i) its eligibility under Section 8.07 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; and

                  (ii) any action taken by the Property Trustee in the
         performance of its duties hereunder which it has not previously
         reported and which in its opinion materially affects the Trust
         Securities.

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


                                      -46-

<PAGE>




            (c) A copy of each such report shall, at the time of such
transmission to Holders, be filed by the Property Trustee with each stock
exchange upon which the Trust Securities are listed, with the Commission and
with the Depositor.

            Section 8.15. Reports to the Property Trustee. The Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee such documents, reports and information (if any) as may be required by
Section 314 of the Trust Indenture Act and the compliance certificate required
by Section 314 of the Trust Indenture Act, in each case in the form, in the
manner and at the times required by Section 314 of the Trust Indenture Act.

            Section 8.16. Evidence of Compliance with Conditions Precedent. Each
of the Depositor and the Administrative Trustees on behalf of the 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 may be given in the form of an Officers'
Certificate.

            Section 8.17. Number of Trustees. (a) The number of Trustees shall
be four, provided that the Depositor, by written instrument, may increase or
decrease the number of Trustees.

            (b) If a Trustee ceases to hold office for any reason, and the
number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or
if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy
shall occur. The vacancy shall be filled with a Trustee appointed in accordance
with Section 8.10.

            (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust. 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 Section 8.10, 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.

            Section 8.18. Delegation of Power. (a) Any Administrative Trustee
may, by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing
any documents contemplated in Section 2.07(a), including any registration


                                      -47-

statement or amendment thereto filed with the Commission, or making any other
governmental filing.

            (b) The Administrative Trustees shall have power to delegate from
time to time to such of their number the doing of such things and the execution
of such instruments either in the name of the 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 the Trust, as set forth herein.


                                   ARTICLE IX

                           TERMINATION AND LIQUIDATION

            Section 9.01. Termination upon Expiration Date. Unless earlier
terminated, the Trust shall automatically terminate on September 1, 2036 (the
"expiration date"), following the distribution of the Trust Property in
accordance with Section 9.04.

            Section 9.02. Early Termination. Upon the first to occur of any of
the following events (such first occurrence, an "Early Termination Event"):

                  (i)   the occurrence of a Bankruptcy Event in
         respect of, or the dissolution or liquidation of, a
         Common Securityholder;

                  (ii)   the Depositor has elected to cause the Trust
         to be dissolved pursuant to Section 4.02(b);

                  (iii)   the redemption of all of the Preferred
         Securities; and

                  (iv)   the issuance of an order for dissolution of the
         Trust by a court of competent jurisdiction;

the Trust shall automatically terminate following (except in the case of clause
(i)) the distribution of the Trust Property in accordance with Section 9.04.

            Section 9.03. Termination. Except in the case of a termination
pursuant to Section 9.02(i), the respective obligations and responsibilities of
the Trustees and the Trust created and continued hereby shall terminate upon the
latest to occur of the following: (i) the distribution by the Property Trustee
to Securityholders, upon the liquidation of the Trust pursuant to Section 9.04,
or upon the redemption of all of the Trust Securities pursuant to Section 4.02,
of all amounts required to be distributed hereunder upon the final payment of
the Trust Securities; (ii) the payment of any expenses owed by the Trust; and
(iii) the discharge


                                      -48-

<PAGE>



of all administrative duties of the Administrative Trustees, including the
performance of any tax reporting obligations with respect to the Trust and the
Securityholders. In the case of a termination pursuant to Section 9.02(i), the
respective obligations and responsibilities of the Trustees and the Trust
created and continued hereby shall terminate without any further action upon the
occurrence of the event specified in Section 9.02(i).

            Section 9.04. Liquidation. (a) If an Early Termination Event
specified in clause (ii) of Section 9.02 occurs, the Trustees shall, as
expeditiously as the Trustees determine to be practicable, make a final
distribution (a "Final Distribution") distributing, subject to receipt of an
Opinion of Counsel as specified in Section 4.02(b), to each Securityholder a
Like Amount of Debentures, subject to Section 9.04(e). Notice of such Final
Distribution shall be given by the Administrative Trustees by first-class mail,
postage prepaid, mailed not later than 30 nor more than 60 days prior to the
Final Distribution Date to each Holder of Trust Securities at such Holder's
address appearing in the Securities Register. Any such notice of Final
Distribution shall:

                  (i)   state the Liquidation Date;

                  (ii) state that from and after the Final Distribution 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 9.04(e) applies receive a Final Distribution,
         as the Administrative Trustees or the Property Trustee shall
         deem appropriate.

            (b) If an Early Termination Event specified in clause (i) of Section
9.02 occurs, a Liquidating Trustee may be appointed (which Liquidating Trustee
may be the same Person as the Property Trustee) by Act of the Securityholders of
a majority in aggregate Liquidation Amount of the Outstanding Trust Securities
or by a court of competent jurisdiction. Any such Liquidating Trustee shall
(unless otherwise instructed by a court of competent jurisdiction) distribute
the Trust Property in substantially the same manner as described in Section
9.04(a), (c) and (d), or, if deemed appropriate by such Liquidating Trustee,
shall liquidate the Trust Property and distribute the proceeds in substantially
the same manner as described in Section 9.04(e).

            (c) Except where Section 9.04(e) applies, in order to effect the
Final Distribution of the Debentures to Securityholders,


                                      -49-

<PAGE>



the Property Trustee shall establish a record date for such distribution (which
shall be not more than 45 days prior to the Final Distribution Date) and, either
itself acting as exchange agent or through the appointment of a separate
exchange agent, shall establish such procedures as it shall deem appropriate to
effect the distribution of Debentures in exchange for the Outstanding Trust
Securities Certificates.

            (d) Except where Section 9.04(e) applies, after the Final
Distribution Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to Holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
SPS shall use its reasonable efforts to have the Debentures listed on the New
York Stock Exchange or on such other exchanges as the Preferred Securities are
then listed, (iv) any Trust Securities Certificates not so surrendered for
exchange will be deemed to represent a Like Amount of Debentures, accruing
interest at the rate provided for in the Debentures from the last Distribution
Date on which a Distribution was made on such Trust Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will cease, except the right of such
Securityholders to receive Debentures upon surrender of Trust Securities
Certificates.

            (e) In the event that, notwithstanding the other provisions of this
Section 9.04, 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 (or the Liquidating
Trustee if one is appointed pursuant to Section 9.04(b)) not to be practical,
the Trust Property shall be liquidated, the proceeds distributed and the Trust
Certificates canceled by the Property Trustee in such manner as the Property
Trustee determines. In such event, on the date specified by the Property
Trustee, Securityholders will be entitled to receive out of the assets of the
Trust available for distribution to Securityholders, after satisfaction of
liabilities to creditors, an amount equal to the Liquidation Amount per Trust
Security plus accrued and unpaid Distributions thereon to the date of payment
(such amount being the "Liquidation Distribution"). If the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then, subject
to the next succeeding sentence, the amounts payable by the Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The Holder of the Common Securities will be entitled to receive Liquidation
Distributions upon any such termination pro rata (determined as aforesaid) with


                                      -50-

<PAGE>



Holders of Preferred Securities, except that, if an Event of Default has
occurred and is continuing, the Preferred Securities shall have a priority over
the Common Securities.

            Section 10.01. Limitation on Rights of Securityholders. The death or
incapacity of any person having an interest, beneficial or otherwise, in a Trust
Security shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of such person or any Securityholder 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.

from time to time by the Trustees and the Depositor, without the consent of any
Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which 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 Trust
will not be classified for United States Federal income tax purposes as an
association taxable as a corporation at any time that any Trust Securities are
outstanding or to ensure that the Trust will not be required to register as an
"investment company" under the Investment Company Act of 1940, as amended;
provided, however, that such amendment or action shall not adversely affect the
rights of any Securityholder and, in the case of clause (i), any amendments of
this Trust Agreement shall become effective only when notice thereof is given to
the Securityholders.

            (b) Except as provided in Section 10.02(c) hereof, any provision of
this Trust Agreement may be amended by the Trustees and the Depositor with (i)
the consent of Trust Securityholders representing not less than a majority
(based upon Liquidation Amounts) of the Trust Securities then Outstanding and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax purposes or cause the Trust to fail or cease to
qualify for an exemption from the status of an "investment company" under the
Investment Company Act of 1940, as amended.


                                      -51-

            (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.03 or 6.06 hereof), this
Trust Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such Distribution on or after such date.
Notwithstanding any other provision herein, without the unanimous consent of the
Securityholders (such consent being obtained in accordance with Section 6.03 or
6.06 hereof), paragraph (b) of this Section 10.02 may not be amended.

            (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for an exemption from
status of an "investment company" under the Investment Company Act of 1940, as
amended.

            (e) Notwithstanding anything in this Trust Agreement to the
contrary, without the consent of the Depositor, this Trust Agreement may not be
amended in a manner which imposes any additional obligation on the Depositor.

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

            (g) The Property Trustee shall not be required to enter into any
amendment to this Trust Agreement which 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 10.03. 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 10.04. Tax Elections. Each holder of Trust Securities,
including any subsequent holder of Trust Securities, by accepting a Trust
Security grants to the Depositor a power of attorney to file any election
(including any protective election) that is necessary or desirable to cause the
Trust to be treated for income tax purposes as a grantor trust and/or not as an
association taxable as a corporation.

the Property Trustee shall be deemed to have been sufficiently given or made
only upon actual receipt of the writing by the Trust or the Property Trustee.

            Section 10.10. Agreement Not to Petition. Each of the Trustees and
the Depositor agree for the benefit of the Securityholders that, until at least
one year and one day after the Trust has been terminated in accordance with
Article IX, they shall not file, or join in the filing of, a petition against
the Trust under any bankruptcy, reorganization, arrangement, insolvency,
liquidation or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.10, the
Property Trustee agrees, for the benefit of Securityholders, that, at the
expense of Depositor, the Property Trustee will file an answer with the
bankruptcy court or otherwise properly contest the filing of such petition
against the 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 Trustee or the Trust may assert. The provisions of this Section 10.10 shall
survive the termination of this Trust Agreement.

            Section 10.11. Trust Indenture Act; Conflict with Trust Indenture
Act. (a) This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are required to be part of this Trust Agreement and shall, to
the extent applicable, be governed by such provisions.

            (b) The Property Trustee shall be the only 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 to be included in this Trust
Agreement by any of the required provisions of the Trust Indenture Act or
otherwise limits, qualifies or conflicts with the duties imposed by Sections 310
through 317 inclusive of the Trust Indenture Act, such required or imposed
provision shall control.

            (d) The application of the Trust Indenture Act to this Trust
Agreement shall not affect the nature of the Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

            THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST
THEREIN BY OR ON BEHALF OF A SECURITYHOLDER OR ANY OWNER, WITHOUT ANY SIGNATURE
OR FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL
ACCEPTANCE BY THE SECURITYHOLDER AND

            Re:  Southwestern Public Service Capital I
                 7.85% Trust Preferred Securities, Series A


Ladies and Gentlemen:

            The purpose of this letter is to set forth certain matters relating
to the issuance and deposit with The Depository Trust Company ("DTC") of the
Southwestern Public Service Capital I 7.85% Trust Preferred Securities, Series A
(the "Preferred Securities"), of Southwestern Public Service Capital I, a
Delaware business trust (the "Issuer"), formed pursuant to a Trust Agreement
between David M. Wilks, as Initial Depositor and Wilmington Trust Company (the
"Bank"), as amended and restated in an Amended and Restated Trust Agreement
dated as of October 21, 1996 among the Initial Depositor, Southwestern Public
Service Company ("SPS"), the Bank and David M. Wilks, Robert D. Dickerson, and
James D. Steinhilper as Trustees (the "Trustees"). The payment of distributions
on the Preferred Securities and payments due upon liquidation of the Issuer or
redemption of the Preferred Securities are to be guaranteed by SPS to the extent
set forth in a Guarantee Agreement dated October 21, 1996 by SPS and Wilmington
Trust Company, as guarantee trustee, with respect to the Preferred Securities.
SPS and the Issuer propose to sell the Preferred Securities to certain
Underwriters (the "Underwriters") pursuant to an Underwriting Agreement dated
October 16, 1996 by and among the Underwriters, the Issuer and SPS, and the
Underwriters wish to take delivery of the Preferred Securities through DTC.

            To induce DTC to accept the Preferred Securities as eligible for
deposit at DTC, and to act in accordance with DTC's Rules with respect to the
Preferred Securities, the Issuer and Wilmington Trust Company make the following
representations to DTC:

            1. Prior to the closing of the sale of the Preferred Securities to
the Underwriters, which is expected to occur on or about October 21, 1996, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's nominee,
Cede & Co., representing an aggregate of up to 4,000,000 Preferred Securities
and bearing the following legend:

                  Unless this certificate is presented by an authorized
                  representative of The Depository Trust Company, a New York
                  corporation ("DTC"), to the Issuer or its agent for
                  registration of transfer, exchange, or payment, and

                                       B-1

<PAGE>



                  any certificate issued is registered in the name of Cede & Co.
                  or in such other name as is requested by an authorized
                  representative of DTC (and any payment is made to Cede & Co.
                  or to such other entity as is requested by an authorized
                  representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
                  HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
                  inasmuch as the registered owner hereof, Cede & Co., has an
                  interest herein.

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

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

            4. In the event of distribution on, or an offering or issuance of
rights with respect to, the Preferred Securities outstanding, the Issuer or the
Bank shall send DTC a notice specifying: (a) the amount of and conditions, if
any, applicable to the payment of any such distribution or any such offering or
issuance of rights; (b) any applicable expiration or deadline date, or any date
by which any action on the part of the holders of Preferred Securities is
required; and (c) the date any required notice is to be mailed by or on behalf
of the Issuer to holders of Preferred Securities or published by or on behalf of
the Issuer (whether by mail or publication, the "Publication Date"). Such notice
shall be sent to DTC by a secure means (e.g., legible telecopy, registered or
certified mail, overnight delivery) in a timely manner designed to assure that
such notice is in DTC's possession no later than the close of business on the
business day before the Publication Date. The Issuer or the Bank will forward
such notice either in a separate secure transmission for each CUSIP number or in
a secure transmission for multiple CUSIP numbers (if applicable) that includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such
means and the timeliness of such notice.) The Publication Date shall be not less
than 30 calendar days nor more than 60 calendar days prior to the payment of any
such distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Bank will notify DTC's Dividend
Department of such payment 5 business days prior to payment date. Notices to
DTC's Dividend Department by telecopy shall be sent to (212) 709-1723. Such
notices by mail or by any other means shall be sent to:

                           Manager, Announcements
                           Dividend Department
                           The Depository Trust Company

                           New York, New York  10004-2695

            The Issuer or the Bank shall confirm DTC's receipt of such telecopy
by telephoning the Dividend Department at (212) 709-1270.

            5. In the event of a redemption by the Issuer of the Preferred
Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Bank to DTC not less than
30 calendar days prior to such event by a secure means in the manner set forth
in paragraph 4. Such redemption notice shall be sent to DTC's Call Notification
Department

                                       B-2

<PAGE>



at (516) 227-4164 or (516) 227-4190, and receipt of such notice shall be
confirmed by telephoning (516) 227-4070. Notice by mail or by any other means
shall be sent to:

                           Call Notification Department
                           The Depository Trust Company
                           711 Stewart Avenue
                           Garden City, New York  11530-4719

            6. In the event of any invitation to tender the Preferred
Securities, notice specifying the terms of the tender and the Publication Date
of such notice shall be sent by the Issuer or the Bank to DTC by a secure means
and in a timely manner as described in paragraph 4. Notices to DTC pursuant to
this paragraph and notices of other corporate actions (including mandatory
tenders, exchanges and capital changes), shall be sent, unless notification to
another department is expressly provided for herein, by telecopy to DTC's
Reorganization Department at (212) 709-1093 or (212) 709-1094 and receipt of
such notice shall be confirmed by telephoning (212) 709-6884, or by mail or any
other means to:

                           Manager, Reorganization Department
                           Reorganization Window
                           The Depository Trust Company
                           7 Hanover Square, 23rd Floor
                           New York, New York  10004-2695

            7. All notices and payment advices sent to DTC shall contain the
CUSIP number or numbers of the Preferred Securities and the accompanying
designation of the Preferred Securities, which, as of the date of this letter,
is "Southwestern Public Service Capital I 7.85% Trust Preferred Securities,
Series A."

            8. Distribution payments or other cash payments with respect to the
Preferred Securities evidenced by the Global Certificate shall be governed by
DTC's current Principal and Income Payments Rider, a copy of which is attached
hereto as Annex I. For purposes of this letter, the term "Agent" used in Annex I
shall be deemed to refer to the Bank.

            9. DTC may direct the Issuer and the Bank to use any other telecopy
number or address of DTC as the number or address to which notices or payments
may be sent.

            10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Bank's invitation) necessitating a reduction in the aggregate number of
Preferred Securities outstanding evidenced by the Global Certificate, DTC, in
its discretion: (a) may request the Issuer or the Bank to issue and countersign
a new Global Certificate; or (b) may make an appropriate notation on the Global
Certificate indicating the date and amount of such reduction.

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

                                       B-3

<PAGE>



by the Issuer or the Bank, together with any other documents of transfer
reasonably requested by the Issuer or the Bank.

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

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

            14. The Issuer (a) understands that DTC has no obligation to, and
will not, communicate to its Participants or to any person having an interest in
the Securities any information contained in the Security certificate(s); and (b)
acknowledges that neither DTC's Participants nor any person having an interest
in the Securities shall be deemed to have notice of the provisions of the
Security certificate(s) by virtue of submission of such certificate(s) to DTC.

            Nothing herein shall be deemed to require the Bank to advance funds
on behalf of the Issuer.

                 pursuant to the above by mail or any other means shall be sent
                 to:

            WHEREAS, SPS is the issuer of the Debentures;

            NOW, THEREFORE, in consideration of the purchase by each holder of

            Section 1.01. Guarantee by SPS. Subject to the terms and conditions
hereof, SPS hereby irrevocably and unconditionally guarantees to each person or

Agreement is intended to be for the benefit of, and to be enforceable by, all
such Creditors, whether or not such Creditors have received notice hereof.

            Section 1.02. Term of Agreement. This Agreement shall terminate and
be of no further force and effect upon the date on which there are no Creditors
remaining; provided, however, that this Agreement shall continue to be effective

restore payment of any sums paid under any Obligation for any reason whatsoever.
This Agreement is continuing, irrevocable, unconditional and absolute.

            Section 1.03. Waiver of Notice. SPS hereby waives notice of

                  (b) any failure, omission, delay or lack of diligence on the
part of the Creditors to enforce, assert or exercise any right, privilege, power
or remedy conferred on the Creditors with respect to the Obligations or any
action on the part of the Trust granting indulgence or extension of any kind; or

consent of, SPS with respect to the happening of any of the foregoing.

            Section 1.05. Enforcement. A Creditor may enforce this Agreement
directly against SPS and SPS waives any right or remedy to require that any
action be brought against the Trust or any other person or entity before
proceeding against SPS.

any Preferred Securities of any series are outstanding, this Agreement shall not
be modified or amended in any manner adverse to such Creditor or to the holders
of the Preferred Securities.
