</TABLE>
(1)  An indeterminate principal amount or number of debt securities, common
     stock and/or preferred stock and guarantees of Sempra Energy, an
     indeterminate principal amount of debt securities of Sempra Energy
     Holdings and an indeterminate number of preferred securities of the Trusts
     as may from time to time be issued at indeterminate prices, with an
     aggregate offering price not to exceed $1,000,000,000. Debt securities may
     be issued and sold to the Trusts, in which event the debt securities may
     later be distributed to the holders of preferred securities.
 
(2)  In United States dollars or the equivalent thereof in any other currency,
     composite currency or currency unit as shall result in an aggregate
     initial offering price for all securities of $1,000,000,000.
 
(3)  This amount represents the principal amount of any debt securities issued
     at their principal amount, the issue price of any debt securities issued
     at an original issue discount, the issue price of any preferred stock and
     preferred securities and the amount computed pursuant to Rule 457(c) for
     any common stock.
 
(4)  Estimated solely for the purpose of calculating the registration fee,
     which is calculated in accordance with Rule 457(o) of the rules and
     regulations under the Securities Act of 1933. Rule 457(o) permits the
     registration fee to be calculated on the basis of the maximum offering
     price of all of the securities listed and, therefore, the table does not
     specify by each class information as to the amount to be registered, the
     proposed maximum offering price per unit or the proposed maximum aggregate
     offering price.
 
(5)  The Rights are initially carried and traded with the common stock. The
     value attributable to the Rights, if any, is reflected in the value of the
     common stock.
 
(6)  Also includes an indeterminate number of securities that may be issued
     upon conversion or exchange of any securities registered hereunder that
     provide for conversion or exchange.
 
(7)  Includes the rights of holders of the preferred securities under the
     guarantees of preferred securities and back-up undertakings, consisting of
     obligations by Sempra Energy, as set forth in the declaration of trust,
     the applicable indenture and any supplemental indenture thereto, in each
     case as further described in the Registration Statement. No separate
     consideration will be received for any guarantees or any back-up
     undertakings.

  The Registrants hereby amend this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrants
shall file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until this Registration Statement shall become
effective on such date as the Securities and Exchange Commission, acting
pursuant to said Section 8(a), may determine.

                             ABOUT THIS PROSPECTUS
 
  This prospectus is part of a "shelf" registration statement that we filed
with the United States Securities and Exchange Commission, or the "SEC." By
using a shelf registration statement, we may sell up to $1,000,000,000 offering
price of any combination of the securities described in this prospectus from
time to time and in one or more offerings. This prospectus only provides you
with a general description of the securities that we may offer. Each time we
sell securities, we will provide a supplement to this prospectus that contains
specific information about the terms of the securities. The supplement may also
add, update or change information contained in this prospectus. Before
purchasing any securities, you should carefully read both this prospectus and
any supplement, together with the additional information described under the
heading "Where You Can Find More Information."
 
  This prospectus does not contain separate financial statements for Sempra
Energy Holdings or the trusts. Sempra Energy files consolidated financial
information with the SEC that includes Sempra Energy Holdings and each of the
trusts. The trusts do not have any independent function other than to issue
securities and to purchase subordinated notes from Sempra Energy. We do not
believe that additional financial information regarding Sempra Energy Holdings
or the Trusts would be useful to you.
 
  You should rely only on the information contained or incorporated by
reference in this prospectus and in any supplement. We have not authorized any
other person to provide you with different information. If anyone provides you
with different or inconsistent information, you should not rely on it. We will
not make an offer to sell these securities in any jurisdiction where the offer
or sale is not permitted. You should assume that the information appearing in
this prospectus and the supplement to this prospectus is accurate as of the
dates on their covers. Our business, financial condition, results of operations
and prospects may have changed since that date.

                           FORWARD-LOOKING STATEMENTS
 
  This prospectus, any accompanying prospectus supplement and the additional
information described under the heading "Where You Can Find More Information"
may contain forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. These statements are subject to risks
and uncertainties and are based on the beliefs and assumptions of our
management, based on information currently available to our management. When we
use words such as "believes," "expects," "anticipates," "intends," "plans,"
"estimates," "should" or similar expressions, we are making forward-looking
statements. Forward-looking statements include the information concerning
possible or assumed future results of operations set forth under "Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in our Annual Report on Form 10-K incorporated by reference into
this prospectus.
 
  Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. Our future results and shareholder value
may differ materially from those expressed in these forward-looking statements.
Many of the factors that will determine these results and value are beyond our
ability to control or predict. These statements are necessarily based upon
various assumptions involving judgments with respect to the future including,
among others, our ability to achieve synergies and revenue growth, national,
international, regional and local economic, competitive and regulatory
conditions and developments, technological developments, capital market
conditions, inflation rates, interest rates, energy markets, weather
conditions, business and regulatory or legal decisions, the pace of
deregulation of retail natural gas and electricity, the timing and extent of
changes in commodity prices for oil, natural gas and electricity, and some
agricultural products, the timing and success of business development efforts,
and other uncertainties, all of which are difficult to predict and many of
which are beyond our control. You are cautioned not to put undue reliance on
any forward-looking statements. For those statements, we claim the protection
of the safe harbor for forward-looking statements contained in the Private
Securities Litigation Reform Act of 1995.
 
  You should also consider any other factors contained in this prospectus or in
any accompanying supplement, including the information incorporated by
reference into this prospectus or into any accompanying supplement.

                                   THE TRUSTS
 
  Sempra Energy created three Delaware business trusts pursuant to three
Declarations of Trust. The trusts are named Sempra Energy Capital Trust I,
Sempra Energy Capital Trust II and Sempra Energy Capital Trust III. Sempra
Energy will file an Amended and Restated Declaration of Trust (a "Declaration")
for each trust, which will state the terms and conditions for each trust to
issue and sell its preferred securities and common securities. A form of
Declaration is filed as an exhibit to the registration statement of which this
prospectus forms a part.
 
  Each trust will exist solely to:
 
  . issue and sell its preferred securities (representing undivided
    beneficial interests in the trust) to the public;
 
  . issue and sell its common securities (representing undivided beneficial
    interests in the trust) to Sempra Energy;
 
  . use the proceeds from the sale of its preferred and common securities to
    purchase a series of Sempra Energy's subordinated debt securities;
 
  . distribute the cash payments it receives on the subordinated debt
    securities it owns to the holders of the preferred and common securities;
 
  . maintain its status as a grantor trust for federal income tax purposes;
    and
 
  . engage in other activities that are necessary or incidental to these
    purposes.
 
  Sempra Energy will purchase all of the common securities of each trust. The
common securities will represent an aggregate liquidation amount equal to at
least 3% of each trust's total capitalization. The preferred securities will
represent the remaining 97% of the trust's total capitalization. The common
securities will have terms substantially identical to, and will rank equal in
priority of payment with, the preferred securities. However, if Sempra Energy
defaults on the related subordinated debt securities, then cash distributions
and liquidation, redemption and other amounts payable on the common securities
will be subordinate to the preferred securities in priority of payment.
 
  The preferred securities will be guaranteed by Sempra Energy as described
later in this prospectus.
 
  Sempra Energy has appointed five trustees to conduct each trust's business
and affairs:
 
  . The Bank of New York ("property trustee");
 
  . The Bank of New York ("Delaware trustee"); and
 
  . Three Sempra Energy officers ("regular trustees").
 
  Only Sempra Energy, as owner of the common securities, can remove or replace
the trustees. In addition, Sempra Energy can increase or decrease the number of
trustees. However, the majority of trustees will always be regular trustees.
 
  Sempra Energy will pay all fees and expenses related to each trust and each
offering of the related preferred securities and will pay all ongoing costs and
expenses of each trust, except the respective trust's obligations under the
related preferred and common securities.
 
                                       5
<PAGE>
 
  The trusts will not have separate financial statements. The statements would
not be material to holders of the preferred securities because no trust will
have any independent operations. Each trust exists solely for the reasons
summarized above.
 
                                USE OF PROCEEDS
 
  Unless stated otherwise in the applicable prospectus supplement, the net
proceeds from the sale of the offered securities will be:
 
  . used by Sempra Energy and/or its subsidiaries for general corporate
    purposes, including investing in unregulated business activities and
    reducing short-term debt incurred to provide interim financing for such
    purposes; and
 
  . used by the respective trusts to purchase subordinated debt securities of
    Sempra Energy.

                           DESCRIPTION OF SECURITIES
 
  The following is a general description of the terms and provisions of the
securities we may offer and sell by this prospectus. These summaries are not
meant to be a complete description of each security. This prospectus and any
accompanying prospectus supplement will contain the material terms and
conditions for each security. The prospectus supplement may add, update or
change the terms and conditions of the securities as described in this
prospectus. For more information about the securities offered by us, please
refer to:
 
  . the indenture between Sempra Energy and Citibank, N.A., as trustee
    relating to the issuance of each series of senior debt securities by
    Sempra Energy;
 
  . the indenture ("subordinated indenture") between Sempra Energy and The
    Bank of New York, as trustee relating to the issuance of each series of
    subordinated debt securities by Sempra Energy;
 
  . the indenture among Sempra Energy Holdings, Sempra Energy, as Guarantor
    and U.S. Bank Trust Company, as trustee relating to the issuance of each
    series of senior debt securities by Sempra Energy Holdings;
 
  . the Declaration of each trust; and
 
  . Sempra Energy's guarantee of the preferred securities issued by each
    trust.
 
  Forms of these documents are filed as exhibits to the registration statement.
The indentures listed above are sometimes collectively referred to as the
"indentures" and individually referred to as an "indenture." The indentures are
subject to and governed by the Trust Indenture Act of 1939, as amended, and may
be supplemented or amended from time to time following their execution.
 
                         DESCRIPTION OF DEBT SECURITIES
 
  The following description sets forth the general terms and provisions of the
debt securities that Sempra Energy and Sempra Energy Holdings may offer by this
prospectus. The debt securities may be issued as senior debt securities or
subordinated debt securities in the case of Sempra Energy and as senior debt
securities in the case of Sempra Energy Holdings. The indebtedness represented
by the senior debt securities will rank equally with all other unsecured and
unsubordinated debt of the company issuing the senior debt security (either
Sempra Energy or Sempra Energy Holdings). The indebtedness represented by the
subordinated debt securities will rank junior and subordinate in right of
payment to the prior payment in full of the senior debt of Sempra Energy, to
the extent and in the manner set forth in the prospectus supplement for the
securities. See "--Subordination" below. Throughout this description,
references to "we," "us" and "our" should be read to refer to the company
issuing the particular securities, unless the context indicates that "we," "us"
or "our" refers to both Sempra Energy and Sempra Energy Holdings.
 
  Each indenture gives us broad authority to set the particular terms of each
series of debt securities, including the right to modify certain of the terms
contained in the indenture. The particular terms of a series of debt securities
and the extent, if any, to which the particular terms of the issue modify the
terms of the indenture will be described in the prospectus supplement relating
to the debt securities.
 
  Each indenture contains the full legal text of the matters described in this
section. Because this section is a summary, it does not describe every aspect
of the debt securities or the applicable
 
                                       7
<PAGE>
 
indentures. This summary is subject to and qualified in its entirety by
reference to all the provisions of the applicable indenture, including
definitions of terms used in the indenture. We also include references in
parentheses to certain sections of the indentures. Whenever we refer to
particular sections or defined terms of the indentures in this prospectus or in
a prospectus supplement, these sections or defined terms are incorporated by
reference herein or in the prospectus supplement. This summary also is subject
to and qualified by reference to the description of the particular terms of the
debt securities described in the applicable prospectus supplement or
supplements.
 
General
 
  We may issue an unlimited amount of debt securities under the indentures in
one or more series. We need not issue all debt securities of one series at the
same time and, unless otherwise provided, we may reopen a series, without the
consent of the holders of the debt securities of that series, for issuances of
additional debt securities of that series.
 
  The debt securities of Sempra Energy and Sempra Energy Holdings will be
unsecured obligations of the company issuing the security, and the debt
securities of Sempra Energy Holdings will be unconditionally guaranteed by
Sempra Energy as to payment of principal, premium, if any, and interest. See
"Guarantee of Sempra Energy; Holding Company Structure."
 
  Prior to the issuance of each series of debt securities, the terms of the
particular securities will be specified in a supplemental indenture (including
any pricing supplement) and a board resolution of the issuing company or in one
or more officer's certificates of the issuing company pursuant to a
supplemental indenture or a board resolution. We refer you to the applicable
prospectus supplement for a description of the following terms of the series of
debt securities:
 
  (a) the title of the debt securities;
 
  (b) any limit upon the principal amount of the debt securities;
 
  (c) the date or dates on which principal will be payable or how to
      determine the dates;
 
  (d) the rate or rates or method of determination of interest; the date from
      which interest will accrue; the dates on which interest will be
      payable, which we refer to as the "interest payment dates;" and any
      record dates for the interest payable on the interest payment dates;
 
  (e) any obligation or option of the issuing company to redeem, purchase or
      repay debt securities, or any option of the registered holder to
      require the issuing company to redeem or repurchase debt securities,
      and the terms and conditions upon which the debt securities will be
      redeemed, purchased or repaid;
 
  (f) the denominations in which the debt securities will be issuable (if
      other than denominations of $1,000 and any integral multiple thereof);
 
  (g) whether the debt securities are to be issued in whole or in part in the
      form of one or more global debt securities and, if so, the identity of
      the depositary for the global debt securities; and
 
  (h) any other terms of the debt securities.
 
(See Section 301.)

Guarantee of Sempra Energy; Holding Company Structure
 
  Sempra Energy will unconditionally guarantee the payment of principal of and
any premium and interest on the debt securities issued by Sempra Energy
Holdings, when due and payable, whether at the stated maturity date, by
declaration of acceleration, call for redemption or otherwise, in accordance
with the terms of the debt securities and the indenture. These guarantees are
referred to as the "debt securities guarantees" in this prospectus. The debt
securities guarantees will remain in effect until the entire principal of and
any premium and interest on the debt securities has been paid in full or
otherwise discharged in accordance with the provisions of the indenture. (See
Article Fourteen.)
 
  Sempra Energy conducts its operations primarily through its subsidiaries and
substantially all of its consolidated assets are held by its subsidiaries.
Accordingly, Sempra Energy's cash flow and its ability to meet its obligations
under its debt securities and the debt securities guarantees are largely
dependent upon the earnings of its subsidiaries and the distribution or other
payment of these earnings to Sempra Energy in the form of dividends or loans or
advances and repayment of loans and advances from Sempra Energy. The
subsidiaries are separate and distinct legal entities and have no obligation to
pay any amounts due on the Sempra Energy debt securities or to make any funds
available for payment of amounts due on these debt securities or, except for
Sempra Energy Holdings, the debt securities guarantees.
 
  Because Sempra Energy is a holding company, its obligations under the debt
securities and the debt securities guarantees will be effectively subordinated
to all existing and future liabilities of its subsidiaries. Therefore, Sempra
Energy's rights and the rights of its creditors, including the rights of the
holders of the debt securities issued by Sempra Energy and any debt securities
guarantees, to participate in the assets of any subsidiary upon the liquidation
or reorganization of the subsidiary will be subject to the prior claims of the
subsidiary's creditors. To the extent that Sempra Energy may itself be a
creditor with recognized claims against any of its subsidiaries, Sempra
Energy's claims would still be effectively subordinated to any security
interest in, or mortgages or other liens on, the assets of the subsidiary and
would be subordinated to any indebtedness or other liabilities of the
subsidiary senior to that held by Sempra Energy. Although agreements to which
Sempra Energy and its subsidiaries are parties limit the incurrence of
additional indebtedness, both Sempra Energy and its subsidiaries retain the
ability to incur substantial additional indebtedness and other liabilities.
 
  In addition, Sempra Energy Holdings also conducts its operations primarily
through its subsidiaries and substantially all of its consolidated assets are
held by its subsidiaries. Accordingly, the discussion above is equally
applicable to Sempra Energy Holdings and the debt securities it issues.
 
Payment of Debt Securities--Interest
 
  Unless indicated differently in a prospectus supplement, we will pay interest
on the debt security on each interest payment date by check mailed to the
person in whose name the debt security is registered as of the close of
business on the regular record date relating to the interest payment date,
except that interest payable at stated maturity, upon redemption or otherwise,
will be paid to the person to whom principal is paid.
 
  However, if we default in paying interest on a debt security, we will pay
defaulted interest in either of the two following ways:
 
  (a) We will first propose to the trustee a payment date for the defaulted
      interest. Next, the trustee will choose a special record date for
      determining which registered holders are
 
                                       9
<PAGE>
 
     entitled to the payment. The special record date will be between 10 and
     15 days before the payment date we propose. Finally, we will pay the
     defaulted interest on the payment date to the registered holder of the
     debt security as of the close of business on the special record date.
 
  (b) Alternatively, we can propose to the trustee any other lawful manner of
      payment that is consistent with the requirements of any securities
      exchange on which the debt securities are listed for trading. If the
      trustee thinks the proposal is practicable, payment will be made as
      proposed.
 
(See Section 307.)
 
Payment of Debt Securities--Principal
 
  Unless we indicate differently in a prospectus supplement, we will pay
principal of and any premium and interest on the debt securities at stated
maturity, upon redemption or otherwise, upon presentation of the debt
securities at the office of the trustee, as our paying agent. Any other paying
agent initially designated for the debt securities of a particular series will
be named in the applicable prospectus supplement.
 
  In our discretion, we may change the place of payment on the debt
securities, and may remove any paying agent and may appoint one or more
additional paying agents. (See Section 1002.)
 
Form; Transfers; Exchanges
 
  The debt securities will be issued
 
  (a) only in fully registered form;
 
  (b) without interest coupons; and
 
  (c) in denominations that are even multiples of $1,000.
 
  You may have your debt securities divided into debt securities of smaller
denominations (of at least $1,000) or combined into debt securities of larger
denominations, as long as the total principal amount is not changed. This is
called an "exchange."
 
  You may exchange or transfer debt securities at the office of the trustee.
The trustee acts as our agent for registering debt securities in the names of
holders and transferring debt securities. We may appoint another agent or act
as our own agent for this purpose. The entity performing the role of
maintaining the list of registered holders is called the "security registrar."
It will also perform transfers.
 
  In our discretion, we may change the place for registration of transfer of
the debt securities and may remove and/or appoint one or more additional
security registrars. (See Sections 305 and 1002.)
 
  Except as otherwise provided in a prospectus supplement, there will be no
service charge for any transfer or exchange of the debt securities, but you
may be required to pay a sum sufficient to cover any tax or other governmental
charge payable in connection with the transfer or exchange. We may block the
transfer or exchange of (a) debt securities during a period of 15 days prior
to giving any notice of redemption or (b) any debt security selected for
redemption in whole or in part, except the unredeemed portion of any debt
security being redeemed in part. (See Section 305.)
 
                                      10
<PAGE>
 
Redemption
 
  We will set forth any terms for the redemption of debt securities in a
prospectus supplement. Unless we indicate differently in a prospectus
supplement, and except with respect to debt securities redeemable at the option
of the registered holder, debt securities will be redeemable upon notice by
mail between 30 and 60 days prior to the redemption date. If less than all of
the debt securities of any series or any tranche of a series are to be
redeemed, the trustee will select the debt securities to be redeemed. In the
absence of any provision for selection, the trustee will choose a method of
random selection it deems fair and appropriate. (See Sections 1102, 1103 and
1104.)
 
  Debt securities will cease to bear interest on the redemption date. We will
pay the redemption price and any accrued interest once you surrender the debt
security for redemption. (See Section 1105.) If only part of a debt security is
redeemed, the trustee will deliver to you a new debt security of the same
series for the remaining portion without charge. (Section 1106.)
 
  We may make any redemption conditional upon the receipt by the paying agent,
on or prior to the date fixed for redemption, of money sufficient to pay the
redemption price. If the paying agent has not received the money by the date
fixed for redemption, we will not be required to redeem the debt securities.
(See Section 1104.)
 
Events of Default
 
  An "event of default" occurs with respect to debt securities of any series
if:
 
  (a) we do not pay any interest on any debt securities of the applicable
      series within 60 days of the due date;
 
  (b) we do not pay principal or premium on any debt securities of the
      applicable series on its due date;
 
  (c) we remain in breach of a covenant or warranty (excluding covenants and
      warranties solely applicable to a specific series) of the indenture for
      90 days after we receive a written notice of default stating we are in
      breach and requiring remedy of the breach; the notice must be sent by
      either the trustee or registered holders of 25% of the principal amount
      of debt securities of the affected series;
 
  (d) the debt securities guarantees on any series
 
    (1) cease to be effective (except in accordance with their terms),
 
    (2) are found in any judicial proceeding to be unenforceable or
        invalid, or
 
    (3) are denied or disaffirmed (except in accordance with their terms);
 
  (e) we file for bankruptcy or other specified events in bankruptcy,
      insolvency, receivership or reorganization occur; or
 
  (f) any other event of default specified in the prospectus supplement
      occurs.
 
(See Section 501.)
 
  No event of default with respect to a series of debt securities necessarily
constitutes an event of default with respect to the debt securities of any
other series issued under the indenture.
 
                                       11
<PAGE>
 
Remedies
 
 Acceleration
 
  If an event of default occurs and is continuing with respect to any series of
debt securities, then either the trustee or the registered holders of 25% in
principal amount of the outstanding debt securities of that series may declare
the principal amount of all of the debt securities of that series to be due and
payable immediately. (See Section 502.)
 
 Rescission of Acceleration
 
  After the declaration of acceleration has been made and before the trustee
has obtained a judgment or decree for payment of the money due, the declaration
and its consequences will be rescinded and annulled, if
 
  (a) we pay or deposit with the trustee a sum sufficient to pay
 
    (1) all overdue interest;
 
    (2) the principal of and any premium which have become due otherwise
        than by the declaration of acceleration and overdue interest on
        these amounts;
 
    (3) interest on overdue interest to the extent lawful;
 
    (4)  all amounts due to the trustee under the indenture; and
 
  (b) all events of default, other than the nonpayment of the principal which
      has become due solely by the declaration of acceleration, have been
      cured or waived as provided in the indenture.
 
(See Section 502.)
 
  For more information as to waiver of defaults, see "Waiver of Default and of
Compliance" below.
 
 Control by Registered Holders; Limitations
 
  Subject to the indenture, if an event of default with respect to the debt
securities of any one series occurs and is continuing, the registered holders
of a majority in principal amount of the outstanding debt securities of that
series will have the right to
 
  (a) direct the time, method and place of conducting any proceeding for any
      remedy available to the trustee, or
 
  (b) exercise any trust or power conferred on the trustee with respect to
      the debt securities of the series.
 
  If an event of default is continuing with respect to more than one series of
debt securities, the registered holders of a majority in aggregate principal
amount of the outstanding debt securities of all the series, considered as one
class, will have the right to make such direction, and not the registered
holders of the debt securities of any one of the series. These rights of
registered holders to make direction are subject to the following limitations:
 
  (a) the registered holders' directions will not conflict with any law or
      the indenture; and
 
  (b) the registered holders' directions may not involve the trustee in
      personal liability where the trustee believes indemnity is not
      adequate.
 
                                       12
<PAGE>
 
  The trustee may also take any other action it deems proper which is
consistent with the registered holders' direction. (See Sections 512 and 603.)
 
  In addition, the indenture provides that no registered holder of any debt
security will have any right to institute any proceeding, judicial or
otherwise, with respect to the indenture for the appointment of a receiver or
for any other remedy thereunder unless
 
  (a) that registered holder has previously given the trustee written notice
      of a continuing event of default;
 
  (b) the registered holders of 25% in aggregate principal amount of the
      outstanding debt securities of all affected series, considered as one
      class, have made written request to the trustee to institute
      proceedings in respect of that event of default and have offered the
      trustee reasonable indemnity against costs and liabilities incurred in
      complying with the request; and
 
  (c) for 60 days after receipt of the notice, the trustee has failed to
      institute a proceeding and no direction inconsistent with the request
      has been given to the trustee during the 60-day period by the
      registered holders of a majority in aggregate principal amount of
      outstanding debt securities of all affected series, considered as one
      class.
 
Furthermore, no registered holder will be entitled to institute any action if
and to the extent that the action would disturb or prejudice the rights of
other registered holders. (See Sections 507 and 603.)
 
  However, each registered holder has an absolute and unconditional right to
receive payment when due and to bring a suit to enforce that right. (See
Sections 507 and 508.)
 
Notice of Default
 
  The trustee is required to give the registered holders of the debt securities
notice of any default under the indenture to the extent required by the Trust
Indenture Act, unless the default has been cured or waived; except that in the
case of an event of default of the character specified above in clause (c)
under "Events of Default," no notice shall be given to the registered holders
until at least 75 days after the occurrence thereof. (See Section 602.) The
Trust Indenture Act currently permits the trustee to withhold notices of
default (except for certain payment defaults) if the trustee in good faith
determines the withholding of the notice to be in the interests of the
registered holders.
 
  We will furnish the trustee with an annual statement as to the compliance by
the company issuing the debt security with the conditions and covenants in the
indenture. (See Section 1005.)
 
Waiver of Default and of Compliance
 
  The registered holders of a majority in aggregate principal amount of the
outstanding debt securities of any series may waive, on behalf of the
registered holders of all debt securities of the series, any past default under
the indenture, except a default in the payment of principal, premium or
interest, or with respect to compliance with certain provisions of the
indenture that cannot be amended without the consent of the registered holder
of each outstanding debt security. (See Section 513.)
 
  Compliance with certain covenants in the indenture or otherwise provided with
respect to debt securities may be waived by the registered holders of a
majority in aggregate principal amount of the affected debt securities,
considered as one class. (See Section 1006.)

Consolidation, Merger and Conveyance of Assets as an Entirety; No Financial
Covenants
 
  Subject to the provisions described in the next paragraph, each of Sempra
Energy and Sempra Energy Holdings will preserve its corporate existence. (See
Section 1004.)
 
  Sempra Energy and Sempra Energy Holdings have each agreed not to consolidate
with or merge into any other entity, and Sempra Energy has agreed not to
convey, transfer or lease its properties and assets substantially as an
entirety to any entity, unless:
 
  (a) the entity formed by the consolidation or into which Sempra Energy or
      Sempra Energy Holdings, as the case may be, is merged, or the entity
      which acquires or which leases the property and assets of Sempra Energy
      substantially as an entirety, is an entity organized and existing under
      the laws of the United States of America or any State thereof or the
      District of Columbia, and expressly assumes, by supplemental indenture,
      the due and punctual payment of the principal, premium and interest on
      all the outstanding debt securities (or the debt securities guarantees
      endorsed thereon, as the case may be) and the performance of all of the
      covenants of Sempra Energy or Sempra Energy Holdings, as the case may
      be, under the indenture, and
 
  (b) immediately after giving effect to the transactions, no event of
      default, and no event which after notice or lapse of time or both would
      become an event of default, will have occurred and be continuing.
 
(See Section 801.)
 
  Neither the indenture nor the debt security guarantee contains any financial
or other similar restrictive covenants. Any such covenants with respect to any
particular series of debt securities will be set forth in the applicable
prospectus supplement.
 
Modification of Indenture
 
  Without Registered Holder Consent. Without the consent of any registered
holders of debt securities, we and the applicable trustee may enter into one or
more supplemental indentures for any of the following purposes:
 
  (a) to evidence the succession of another entity to Sempra Energy or Sempra
      Energy Holdings; or
 
  (b) to add one or more covenants of Sempra Energy or Sempra Energy Holdings
      or other provisions for the benefit of the registered holders of all or
      any series or tranche of debt securities, or to surrender any right or
      power conferred upon Sempra Energy or Sempra Energy Holdings; or
 
  (c) to add any additional events of default for all or any series of debt
      securities; or
 
  (d) to change or eliminate any provision of the indenture or to add any new
      provision to the indenture that does not adversely affect the interests
      of the registered holders; or
 
  (e) to provide security for the debt securities of any series; or
 
  (f) to establish the form or terms of debt securities of any series or
      tranche or any debt securities guarantees as permitted by the
      indenture; or
 
  (g) to provide for the issuance of bearer securities; or
 
                                       14
<PAGE>
 
  (h) to evidence and provide for the acceptance of appointment of a separate
      or successor trustee; or
 
  (i) to provide for the procedures required to permit the utilization of a
      noncertificated system of registration for any series or tranche of
      debt securities; or
 
  (j) to change any place or places where
 
    (1) we may pay principal, premium and interest,
 
    (2) debt securities may be surrendered for transfer or exchange, or
 
    (3) notices and demands to or upon Sempra Energy or Sempra Energy
        Holdings may be served; or
 
  (k) to cure any ambiguity, defect or inconsistency or to make any other
      changes that do not adversely affect the interests of the registered
      holders in any material respect.
 
(See Section 901.)
 
  If the Trust Indenture Act is amended after the date of the indenture so as
to require changes to the indenture or so as to permit changes to, or the
elimination of, provisions which, at the date of the indenture or at any time
thereafter, were required by the Trust Indenture Act to be contained in the
indenture, the indenture will be deemed to have been amended so as to conform
to the amendment or to effect the changes or elimination, and Sempra Energy,
Sempra Energy Holdings and the applicable trustee may, without the consent of
any registered holders, enter into one or more supplemental indentures to
effect or evidence the amendment.
 
  With Registered Holder Consent. We and the trustee may, with some exceptions,
amend or modify any indenture with the consent of the registered holders of at
least a majority in aggregate principal amount of the debt securities of all
series affected by the amendment or modification (voting as one class).
However, no amendment or modification may, without the consent of the
registered holder of each outstanding debt security directly affected thereby,
 
  (a) change the stated maturity of the principal or interest on any debt
      security (other than pursuant to the terms thereof), or reduce the
      principal amount, interest or premium payable or change the currency in
      which any debt security is payable, or impair the right to bring suit
      to enforce any payment;
 
  (b) reduce the percentages of registered holders whose consent is required
      for any supplemental indenture or waiver or reduce the requirements for
      quorum and voting under the indenture; or
 
  (c) modify certain of the provisions in the indenture relating to
      supplemental indentures and waivers of certain covenants and past
      defaults.
 
  A supplemental indenture which changes or eliminates any provision of the
indenture expressly included solely for the benefit of registered holders of
debt securities of one or more particular series or tranches will be deemed not
to affect the rights under the indenture of the registered holders of debt
securities of any other series or tranche. (See Section 902.)
 
Miscellaneous Provisions
 
  The indenture provides that certain debt securities, including those for
which payment or redemption money has been deposited or set aside in trust as
described under "Satisfaction and
 
                                       15
<PAGE>
 
Discharge" below, will not be deemed to be "outstanding" in determining whether
the registered holders of the requisite principal amount of the outstanding
debt securities have given or taken any demand, direction, consent or other
action under the indenture as of any date, or are present at a meeting of
registered holders for quorum purposes. (See Section 101.)
 
  We will be entitled to set any day as a record date for the purpose of
determining the registered holders of outstanding debt securities of any series
entitled to give or take any demand, direction, consent or other action under
the indenture, in the manner and subject to the limitations provided in the
indenture. In certain circumstances, the trustee also will be entitled to set a
record date for action by registered holders. If a record date is set for any
action to be taken by registered holders of particular debt securities, the
action may be taken only by persons who are registered holders of the
respective debt securities on the record date. (See Section 104.)
 
Defeasance and Covenant Defeasance
 
  The indentures provide, unless the terms of the particular series of debt
securities provide otherwise, that we may, upon satisfying several conditions,
cause ourselves to be:
 
  (a) discharged from our obligations, with some exceptions, with respect to
      any series of debt securities, which we refer to as "defeasance"; and
 
  (b) released from our obligations under certain covenants with respect to
      any series of debt securities, which we refer to as "covenant
      defeasance".
 
  One condition we must satisfy is the irrevocable deposit with the trustee, in
trust, of money and/or government obligations which, through the scheduled
payment of principal and interest on those obligations, would provide
sufficient moneys to pay the principal of and any premium and interest on those
debt securities on the maturity dates of the payments or upon redemption.
 
  The indentures permit defeasance with respect to any series of debt
securities even if a prior covenant defeasance has occurred with respect to the
debt securities of that series. Following a defeasance, payment of the debt
securities defeased may not be accelerated because of an event of default.
Following a covenant defeasance, payment of the debt securities may not be
accelerated by reference to the covenants described in the description of
covenant defeasance above. However, if such an acceleration were to occur, the
realizable value at the acceleration date of the money and government
obligations in the defeasance trust could be less than the principal and
interest then due on the respective debt securities, since the required deposit
in the defeasance trust would be based upon scheduled cash flows rather than
market value, which would vary depending upon interest rates and other factors.
 
  Under current United States federal income tax law, the defeasance
contemplated in the preceding paragraphs would be treated as an exchange of the
relevant debt securities in which holders of the debt securities might
recognize gain or loss. In addition, the amount, timing and character of
amounts that holders would be required thereafter to include in income might be
different from that which would be includible in the absence of such
defeasance. Prospective investors are urged to consult their own tax advisors
as to the specific consequences of a defeasance, including the applicability
and effect of tax laws other than United States federal income tax laws.
 
                                       16
<PAGE>
 
  Under current United States federal income tax laws, unless accompanied by
other changes in the terms of the debt securities, covenant defeasance should
not be treated as a taxable exchange.
 
Resignation and Removal of the Trustee; Deemed Resignation
 
  The trustee may resign at any time by giving written notice to us.
 
  The trustee may also be removed by act of the registered holders of a
majority in principal amount of the then outstanding debt securities of any
series.
 
  No resignation or removal of the trustee and no appointment of a successor
trustee will become effective until the acceptance of appointment by a
successor trustee in accordance with the requirements of the indenture.
 
  Under certain circumstances, we may appoint a successor trustee and if the
successor accepts, the trustee will be deemed to have resigned.
 
  (Section 610).
 
Subordination
 
  Unless we indicate differently in a prospectus supplement, any subordinated
debt securities will be subordinated in the following manner. If Sempra
Energy's assets are distributed upon our dissolution, winding up, liquidation
or reorganization, the payment of the principal of (and premium, if any) and
interest on any subordinated debt securities will be subordinated, to the
extent provided in the subordinated debt security indenture and the applicable
supplemental indenture, to the prior payment in full of all senior
indebtedness, including senior debt securities. However, Sempra Energy's
obligation to pay principal (and premium, if any) or interest on the
subordinated debt securities will not otherwise be affected. No payment on
account of principal (or premium, if any), sinking fund or interest may be made
on the subordinated debt securities at any time when there is a default in the
payment of principal, premium, if any, sinking fund or interest on senior
indebtedness. If, while Sempra Energy is in default on senior indebtedness, any
payment is received by the trustee under the subordinated debt security
indenture or the holders of any of the subordinated debt securities before it
has paid all senior indebtedness in full, the payment or distribution must be
paid over to the holders of the unpaid senior indebtedness or applied to the
repayment of the unpaid senior indebtedness. Subject to paying the senior
indebtedness in full, the holders of the subordinated debt securities will be
subrogated to the rights of the holders of the senior indebtedness to the
extent that payments are made to the holders of senior indebtedness out of the
distributive share of the subordinated debt securities.
 
  Due to the subordination, if Sempra Energy's assets are distributed upon
insolvency, certain of its general creditors may recover more, ratably, than
holders of subordinated debt securities. The subordinated debt security
indenture or applicable supplemental indenture may state that its subordination
provisions will not apply to money and securities held in trust under the
satisfaction and discharge, and the legal defeasance provisions of the
subordinated debt security indenture.
 
  If this prospectus is being delivered in connection with the offering of a
series of subordinated debt securities, the accompanying prospectus supplement
or the information incorporated by reference in it will set forth the
approximate amount of senior indebtedness outstanding as of a recent date.

Conversion Rights
 
  The terms and conditions of any debt securities being offered that are
convertible into common stock of Sempra Energy will be set forth in a
prospectus supplement. These terms will include the conversion price, the
conversion period, provisions as to whether conversion will be at the option of
the holder or us, the events requiring an adjustment of the conversion price
and provisions affecting conversion in the event that the debt securities are
redeemed.
 
Governing Law
 
  Each indenture and the related debt securities will be governed by and
construed in accordance with the laws of the State of New York.

                        COMMON STOCK AND PREFERRED STOCK
 
  The following description of Sempra Energy's common stock and preferred stock
is only a summary and is qualified in its entirety by reference to the articles
of incorporation and bylaws of Sempra Energy. Therefore, you should read
carefully the more detailed provisions of Sempra Energy's Amended and Restated
Articles of Incorporation, Sempra Energy's Amended and Restated Bylaws, and
Sempra Energy's Rights Agreement, dated May 26, 1998, between Sempra Energy and
First Chicago Trust Company of New York, as rights agent, copies of which are
incorporated by reference as exhibits to the registration statement of which
this prospectus is a part.

  The authorized capital stock of Sempra Energy consists of (1) 750,000,000
shares of Sempra Energy common stock, without par value, and (2) 50,000,000
shares of preferred stock, without par value. As of February 27, 1999, there
were issued and outstanding 240,119,972 shares of Sempra Energy common stock
and no shares of Sempra Energy preferred stock. No other classes of capital
stock are authorized under the Sempra Energy articles of incorporation. The
issued and outstanding shares of Sempra Energy common stock are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights.
 
Sempra Energy Common Stock
 
  The holders of Sempra Energy common stock are entitled to receive such
dividends as the Sempra Energy board of directors may from time to time
declare, subject to any rights of holders of outstanding shares of Sempra
Energy preferred stock. Except as otherwise provided by law, each holder of
Sempra Energy common stock is entitled to one vote per share on each matter
submitted to a vote of a meeting of shareholders, subject to any class or
series voting rights of holders of Sempra Energy preferred stock. Under the
Sempra Energy articles of incorporation, the Sempra Energy board of directors
is classified into three classes each consisting of a number as nearly equal as
possible to one-third of the total number of directors constituting the entire
Sempra Energy board of directors. The holders of shares of Sempra Energy common
stock are not entitled to cumulate votes for the election of directors.
 
  In the event of any liquidation, dissolution or winding up of Sempra Energy,
whether voluntary or involuntary, the holders of shares of Sempra Energy common
stock, subject to any rights of the holders of outstanding shares of Sempra
Energy preferred stock, are entitled to receive any remaining assets of Sempra
Energy after the discharge of its liabilities.
 
  Holders of Sempra Energy common stock are not entitled to preemptive rights
to subscribe for or purchase any part of any new or additional issue of stock
or securities convertible into stock. Sempra Energy common stock does not
contain any redemption provisions or conversion rights and is not liable to
assessment or further call.
 
  Each outstanding share of Sempra Energy common stock is accompanied by a
right to purchase one one-hundredth of a share of Class A Junior Participating
Preferred Stock, without par value, of Sempra Energy at a price of $80.00 per
right, subject to certain anti-dilution adjustments. The Sempra Energy board of
directors has reserved 7,500,000 shares of such Class A
preferred stock for issuance upon exercise of the rights, as more fully
discussed below under the heading "--Description of Preferred Share Purchase
Rights."
 
                                       19
<PAGE>
 
  The registrar and transfer agent for the Sempra Energy common stock is First
Chicago Trust Company of New York.
 
Preferred Stock
 
  The Sempra Energy board of directors is authorized, pursuant to the Sempra
Energy articles of incorporation, to issue up to 50,000,000 shares of Sempra
Energy preferred stock in one or more series and to fix and determine the
number of shares of preferred stock of any series, to determine the designation
of any such series, to increase or decrease the number of shares of any such
series subsequent to the issue of shares of that series, and to determine or
alter the rights, preferences, privileges and restrictions granted to or
imposed upon any such series. Currently there are no shares of Sempra Energy
preferred stock outstanding. However, the Sempra Energy board of directors has
reserved 7,500,000 shares of Class A preferred stock for issuance in connection
with rights issued under the Sempra Energy rights agreement.
 
  Prior to the issuance of shares of each series of preferred stock, the board
of directors is required to adopt resolutions and file a certificate of
determination with the Secretary of State of the State of California. The
certificate of determination will fix for each series the designation and
number of shares and the rights, preferences, privileges and restrictions of
the shares including, but not limited to, the following:
 
  (a) the title and stated value of the preferred stock;
 
  (b) voting rights, if any, of the preferred stock;
 
  (c) any rights and terms of redemption (including sinking fund provisions);
 
  (d) the dividend rate(s), period(s) and/or payment date(s) or method(s) of
      calculation applicable to the preferred stock;
 
  (e) whether dividends are cumulative or non-cumulative and, if cumulative,
      the date from which dividends on the preferred stock will accumulate;
 
  (f) the relative ranking and preferences of the preferred stock as to
      dividend rights and rights upon the liquidation, dissolution or winding
      up of our affairs;
 
  (g) the terms and conditions, if applicable, upon which the preferred stock
      will be convertible into common stock, including the conversion price
      (or manner of calculation) and conversion period;
 
  (h) the provision for redemption, if applicable, of the preferred stock;
 
  (i) the provisions for a sinking fund, if any, for the preferred stock;
 
  (j) liquidation preferences;
 
  (k) any limitations on issuance of any class or series of preferred stock
      ranking senior to or on a parity with the class or series of preferred
      stock as to dividend rights and rights upon liquidation, dissolution or
      winding up of our affairs; and
 
  (l) any other specific terms, preferences, rights, limitations or
      restrictions of the preferred stock.
 
  All shares of preferred stock will, when issued, be fully paid and
nonassessable and will not have any preemptive or similar rights.
 
                                       20
<PAGE>
 
  In addition to the terms listed above, we will set forth in a prospectus
supplement the following terms relating to the class or series of preferred
stock being offered:
 
  (a) the number of shares of the preferred stock offered, the liquidation
      preference per share and the offering price of the preferred stock;
 
  (b) the procedures for any auction and remarketing, if any, for the
      preferred stock;
 
  (c) any listing of the preferred stock on any securities exchange; and
 
  (d) a discussion of any material and/or special United States federal
      income tax considerations applicable to the preferred stock.
 
 
Rank
 
  Unless we specify otherwise in the applicable prospectus supplement, the
preferred stock will rank, with respect to dividends and upon our liquidation,
dissolution or winding up:
 
  (a) senior to all classes or series of our common stock and to all of our
      equity securities ranking junior to the preferred stock;
 
  (b) on a parity with all of our equity securities the terms of which
      specifically provide that the equity securities rank on a parity with
      the preferred stock; and
 
  (c) junior to all of our equity securities the terms of which specifically
      provide that the equity securities rank senior to the preferred stock.
 
Description of Preferred Share Purchase Rights
 
  On May 26, 1998, the Sempra Energy board of directors adopted a preferred
share purchase rights plan providing that one preferred share purchase right
will attach to each share of Sempra Energy common stock. The description and
terms of the rights are set forth in a rights agreement, dated as of May 26,
1998, by and between Sempra Energy and First Chicago Trust Company of New York,
as rights agent. The purchase rights have an anti-takeover effect that is
intended to discourage coercive or unfair takeover tactics and to encourage any
potential acquirer to negotiate a fair price to all Sempra Energy shareholders.
The purchase rights may cause substantial dilution to any party that may
attempt to acquire Sempra Energy on terms not approved by the Sempra Energy
board of directors. However, the purchase rights are structured in a way so as
not to interfere with any negotiated merger or other business combination. The
rights will expire on May 31, 2008. Until a right is exercised, the holder of
the right will have no rights as a shareholder of Sempra Energy beyond those
rights afforded to existing shareholders, including the right to vote or to
receive dividends.
 
  The rights are designed to assure that all of Sempra Energy's shareholders
receive fair and equal treatment in the event of any proposed takeover of
Sempra Energy and to guard against partial tender offers, open market
accumulations and other abusive tactics that may be deployed to gain control of
Sempra Energy without a control premium paid to all shareholders. Any time
prior to the first date that a person or group has become an "acquiring person"
as defined in the rights agreement, the rights should not interfere with any
merger or other business combination as long as it is approved by the Sempra
Energy board of directors.

Anti-Takeover Provisions
 
  The Sempra Energy articles of incorporation and bylaws contain provisions
that may have the effect of discouraging persons from acquiring large blocks of
Sempra Energy stock or delaying or preventing a change in control of Sempra
Energy. The material provisions which may have such an effect are:
 
  (a) classification of the Sempra Energy board of directors into three
      classes with the term of only one class expiring each year;
 
  (b) a provision permitting the Sempra Energy board of directors to make,
      amend or repeal the Sempra Energy bylaws;
 
  (c) authorization for the Sempra Energy board of directors to issue Sempra
      Energy preferred stock in series and to fix rights and preferences of
      the series (including, among other things, whether, and to what extent,
      the shares of any series will have voting rights and the extent of the
      preferences of the shares of any series with respect to dividends and
      other matters);
 
  (d) a provision that shareholders may take action only at annual or special
      meetings or by unanimous written consent in lieu of a meeting;
 
  (e) advance notice procedures with respect to nominations of directors or
      proposal other than those adopted or recommended by the Sempra Energy
      board of directors; and
 
  (f) provisions permitting amendment of certain of these provisions only by
      an affirmative vote of the holders of at least two-thirds of the
      outstanding shares of Sempra Energy common stock entitled to vote.
 
  Some acquisitions of Sempra Energy's outstanding voting shares would also
require approval of the SEC under the Public Utility Holding Company Act of
1935 and of various state and foreign regulatory authorities.

                      DESCRIPTION OF PREFERRED SECURITIES
 
General
 
  Each Declaration authorizes the regular trustees to issue on behalf of each
trust one series of preferred securities which will have the terms described in
a prospectus supplement. The proceeds from the sale of a trust's preferred and
common securities will be used by the trust to purchase a series of
subordinated debt securities issued by Sempra Energy. The subordinated debt
securities will be held in trust by the property trustee for the benefit of the
holders of the preferred and common securities.
 
  Under each preferred securities guarantee, Sempra Energy will agree to make
payments of distributions and payments on redemption or liquidation with
respect to a trust's preferred securities, but only to the extent the trust has
funds available to make those payments and has not made the payments. See
"Description of Preferred Securities Guarantees."
 
  The assets of a trust available for distribution to the holders of its
preferred securities will be limited to payments from Sempra Energy under the
series of subordinated debt securities held by the trust. If Sempra Energy
fails to make a payment on the subordinated debt securities, the trust will not
have sufficient funds to make related payments, including distributions, on its
preferred securities.
 
  Each preferred securities guarantee, when taken together with Sempra Energy's
obligations under the related series of subordinated debt securities, the
subordinated indenture and the related Declaration, will provide a full and
unconditional guarantee of amounts due on the preferred securities issued by a
trust.
 
  Each Declaration will be qualified as an indenture under the Trust Indenture
Act. Each property trustee will act as indenture trustee for the preferred
securities to be issued by the applicable trust, in order to comply with the
provisions of the Trust Indenture Act.
 
  Each series of preferred securities will have the terms, including
distributions, redemption, voting, liquidation rights and the other preferred,
deferred or other special rights or other restrictions as described in the
relevant Declaration or made part of the Declaration by the Trust Indenture Act
or the Delaware Business Trust Act. The terms of the preferred securities will
mirror the terms of the subordinated debt securities held by the trust.
 
  The prospectus supplement relating to the preferred securities of a trust
will describe the specific terms of the preferred securities, including:
 
  (a) the name of the preferred securities;
 
  (b) the dollar amount and number of securities issued;
 
  (c) any provision relating to deferral of distribution payments;
 
  (d) the annual distribution rate(s) (or method of determining the rate(s)),
      the payment date(s) and the record dates used to determine the holders
      who are to receive distributions;
 
  (e) the date from which distributions shall be cumulative;
 
  (f) the optional redemption provisions, if any, including the prices, time
      periods and other terms and conditions for which the preferred
      securities shall be purchased or redeemed, in whole or in part;
 
                                       23
<PAGE>
 
  (g) the terms and conditions, if any, upon which the applicable series of
      subordinated debt securities may be distributed to holders of the
      preferred securities;
 
  (h) the voting rights, if any, of holders of the preferred securities;
 
  (i) any securities exchange on which the preferred securities will be
      listed;
 
  (j) whether the preferred securities are to be issued in book-entry form
      and represented by one or more global certificates and, if so, the
      depository for the global certificates and the specific terms of the
      depositary arrangements; and
 
  (k) any other relevant rights, preferences, privileges, limitations or
      restrictions of the preferred securities.
 
  Each prospectus supplement will describe certain United States federal income
tax considerations applicable to the purchase, holding and disposition of the
series of preferred securities covered by the prospectus supplement.
 
Liquidation Distribution Upon Dissolution
 
  Unless otherwise specified in an applicable prospectus supplement, each
Declaration states that the related trust shall be dissolved:
 
  (a) on the expiration of the term of the trust;
 
  (b) upon the bankruptcy of Sempra Energy;
 
  (c) upon the filing of a certificate of dissolution or its equivalent with
      respect to Sempra Energy;
 
  (d) after obtaining the consent of at least a majority in liquidation
      amount of the preferred and common securities of the trust, voting
      together as a single class;
 
  (e) 90 days after the revocation of the articles of incorporation of Sempra
      Energy (but only if the articles of incorporation are not reinstated
      during that 90-day period);
 
  (f) upon the distribution of the related subordinated debt securities
      directly to the holders of the preferred and common securities of the
      trust;
 
  (g) upon the redemption of all of the common and preferred securities of
      the trust; or
 
  (h) upon entry of a court order for the dissolution of Sempra Energy, or
      the trust.
 
  Unless otherwise specified in an applicable prospectus supplement, in the
event of a dissolution, after the trust satisfies (whether by payment or
reasonable provision for payment) all amounts owed to creditors, the holders of
the preferred and common securities will be entitled to receive:
 
  (a) cash equal to the aggregate liquidation amount of each preferred and
      common security specified in an accompanying prospectus supplement,
      plus accumulated and unpaid distributions to the date of payment;
      unless
 
  (b) subordinated debt securities in an aggregate principal amount equal to
      the aggregate liquidation amount of the preferred and common securities
      are distributed to the holders of the preferred and common securities.
 
                                       24
<PAGE>
 
  If the trust cannot pay the full amount due on its preferred and common
securities because insufficient assets are available for payment, then the
amounts payable by the trust on its preferred and common securities shall be
paid pro rata. However, if an event of default under the related Declaration
has occurred, the total amounts due on the preferred securities will be paid
before any distribution on the common securities.
 
Declaration Events of Default
 
  An event of default under the subordinated indenture relating to a series of
subordinated debt securities is an event of default under the Declaration of
the trust that owns these subordinated debt securities (a "Declaration event of
default"). See "Description of Debt Securities--Events of Default."
 
  Sempra Energy and the regular trustees of a trust must file annually with the
property trustee for the trust a certificate stating whether or not they are in
compliance with all the applicable conditions and covenants under the related
Declaration.
 
  Upon the occurrence of a Declaration event of default, the property trustee
of the applicable trust, as the sole holder of the subordinated debt securities
held by the trust, will have the right under the subordinated indenture to
declare the principal of, premium, if any, and interest on the subordinated
debt securities to be immediately due and payable.
 
  If a property trustee fails to enforce its rights under the related
Declaration or the subordinated indenture, any holder of the preferred
securities issued by the related trust may, to the fullest extent permitted by
law and subject to the terms of the Declaration and the subordinated indenture,
sue Sempra Energy, or seek other remedies, to enforce the property trustee's
rights under the Declaration or the subordinated indenture without first
instituting a legal proceeding against the property trustee or any other
person.
 
  If Sempra Energy fails to pay principal, premium, if any, or interest on a
series of subordinated debt securities when payable, then a holder of the
related preferred securities issued by a trust which owns the notes may
directly sue Sempra Energy or seek other remedies to collect its pro rata share
of payments owed.
 
Consolidation, Merger or Amalgamation of the Trusts
 
  A trust may not consolidate, amalgamate, merge with or into, convert into, or
be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other corporation or other body ("Merger
Event"), except as described below or as described in "Liquidation Distribution
Upon Dissolution." A trust may, with the consent of a majority of its regular
trustees and without the consent of the holders of its preferred and common
securities, consolidate, amalgamate, merge with or into, convert into, or be
replaced by another trust, if:
 
  (a) the successor entity either
 
    (1) assumes all of the obligations of the trust relating to its
        preferred and common securities; or
 
    (2) substitutes for the trust's preferred and common securities other
        securities substantially similar to the preferred and common
        securities ("successor securities"), so long as the successor
        securities rank the same as the preferred and common securities for
        distributions and payments upon liquidation, redemption and
        otherwise;
 
                                       25
<PAGE>
 
  (b) Sempra Energy acknowledges a trustee of the successor entity who has
      the same powers and duties as the property trustee of the trust as the
      holder of the particular series of subordinated debt securities;
 
  (c) the preferred securities are listed, or any successor securities will
      be listed, upon notice of issuance, on the same national securities
      exchange or other organization that the preferred securities are then
      listed;
 
  (d) the Merger Event does not cause its preferred securities or successor
      securities to be downgraded by any national rating agency;
 
  (e) the Merger Event does not adversely affect the rights, preferences and
      privileges of the holders of its preferred and common securities or
      successor securities in any material way (other than with respect to
      any dilution of the holders' interest in the new entity);
 
  (f) the successor entity has a purpose substantially identical to that of
      the trust;
 
  (g) prior to the Merger Event, Sempra Energy has received an opinion of
      counsel from a nationally recognized law firm stating that:
 
    (1) the Merger Event does not adversely affect the rights of the
        holders of the trust's preferred securities or any successor
        securities in any material way (other than with respect to any
        dilution of the holders' interest in the new entity); and
 
    (2) following the Merger Event, neither the trust nor the successor
        entity will be required to register as an investment company under
        the Investment Company Act of 1940, as amended; and
 
  (h) Sempra Energy guarantees the obligations of the successor entity under
      the successor securities in the same manner as in the applicable
      preferred securities guarantee and the guarantee of the common
      securities for the trust.
 
  In addition, unless all of the holders of the preferred and common securities
approve otherwise, a trust shall not consolidate, amalgamate, merge with or
into, convert into, or be replaced by any other entity or permit any other
entity to consolidate, amalgamate, merge with or into, or replace it, if the
transaction would cause the trust or the successor entity to be classified
other than as a grantor trust for United States federal income tax purposes.
 
Voting Rights; Amendment of Declarations
 
  The holders of preferred securities have no voting rights except as discussed
under "--Consolidation, Merger or Amalgamation of the Trusts" and "Description
of the Preferred Securities Guarantees--Amendments and Assignment," and as
otherwise required by law and the Declaration for the trust.
 
  A Declaration may be amended if approved by a majority of the regular
trustees of the applicable trust. However, if any proposed amendment provides
for, or the regular trustees otherwise propose to effect:
 
  (a) any action that would adversely affect the powers, preferences or
      special rights of the trust's preferred and common securities, whether
      by way of amendment to the Declaration or otherwise; or
 
  (b) the dissolution, winding-up or termination of the trust other than
      pursuant to the terms of its Declaration,
 
                                       26
<PAGE>
 
then the holders of the trust's preferred and common securities as a single
class will be entitled to vote on the amendment or proposal. In that case, the
amendment or proposal will be effective only if approved by at least a majority
in liquidation amount of the preferred and common securities affected by the
amendment or proposal.
 
  If any amendment or proposal referred to in clause (a) above would adversely
affect only the preferred securities or the common securities of a trust, then
only the affected class will be entitled to vote on the amendment or proposal
and the amendment or proposal will only be effective with the approval of at
least a majority in liquidation amount of the affected class.
 
  No amendment may be made to a Declaration if the amendment would:
 
  (a) cause the related trust to be characterized as other than a grantor
      trust for United States federal income tax purposes;
 
  (b) adversely affect the powers, liabilities or duties of the property
      trustee or the Delaware trustee; or
 
  (c) cause the related trust to be deemed to be an "investment company"
      which is required to be registered under the Investment Company Act.
 
  The holders of a majority in aggregate liquidation amount of the preferred
securities of each trust have the right to:
 
  (a) direct the time, method and place of conducting any proceeding for any
      remedy available to the property trustee of the trust; or
 
  (b) direct the exercise of any trust or power conferred upon the property
      trustee under that trust's Declaration, including the right to direct
      the property trustee, as the holder of a series of subordinated debt
      securities, to:
 
    (1) exercise the remedies available under the subordinated indenture
        with respect to the subordinated debt securities;
 
    (2) waive any event of default under the subordinated indenture that is
        waivable; or
 
    (3) cancel an acceleration of the principal of the subordinated debt
        securities.
 
  However, if the subordinated indenture requires the consent of the holders of
more than a majority in aggregate principal amount of a series of subordinated
debt securities (a "super-majority"), then the property trustee for the series
must get approval of the holders of a super-majority in liquidation amount of
the series of preferred securities.
 
  In addition, before taking any of the foregoing actions, the property trustee
must obtain an opinion of counsel stating that, as a result of the action, the
trust will continue to be classified as a grantor trust for United States
federal income tax purposes.
 
  The property trustee of a trust will notify all preferred securities holders
of the trust of any notice received from the trustee of the subordinated
indenture with respect to the subordinated debt securities held by the trust.
 
                                       27
<PAGE>
 
  As described in each Declaration, the property trustee may hold a meeting to
have preferred securities holders vote on a change or have them approve the
change by written consent.
 
  If a vote of preferred securities holders is taken or a consent is obtained,
any preferred securities that are owned by Sempra Energy or any of its
affiliates will, for purposes of the vote or consent, be treated as if they
were not outstanding. This means:
 
  (a) Sempra Energy and any of its affiliates will not be able to vote on or
      consent to matters requiring the vote or consent of holders of
      preferred securities; and
 
  (b) any preferred securities owned by Sempra Energy or any of its
      affiliates will not be counted in determining whether the required
      percentage of votes or consents has been obtained.
 
Removal and Replacement of Trustees
 
  Only the holder of a trust's common securities has the right to remove, or
replace the regular trustees and, prior to an event of default, property and
Delaware trustees of the trust. If an event of default occurs, only the holders
of a trust's preferred securities have the right to remove or replace the
property and Delaware trustees. The resignation or removal of any trustee and
the appointment of a successor trustee shall be effective only on the
acceptance of appointment by the successor trustee in accordance with the
provisions of the Declaration for the trust.
 
Information Concerning the Property Trustees
 
  For matters relating to compliance with the Trust Indenture Act, the property
trustee of each trust will have all of the duties and responsibilities of an
indenture trustee under the Trust Indenture Act. Each property trustee, other
than during the occurrence and continuance of a Declaration event of default
under the applicable trust, undertakes to perform only the duties as are
specifically set forth in the applicable Declaration and, upon a Declaration
event of default, must use the same degree of care and skill as a prudent
person would exercise or use in the conduct of his or her own affairs. Subject
to this provision, a property trustee is under no obligation to exercise any of
the powers given it by the applicable Declaration at the request of any holder
of preferred securities unless it is offered reasonable security or indemnity
against the costs, expenses and liabilities that it might incur. However, the
holders of the preferred securities will not be required to offer an indemnity
where the holders, by exercising their voting rights, direct the property
trustee to take any action following a Declaration event of default.
 
Miscellaneous
 
  The regular trustees of each trust are authorized and directed to conduct the
affairs of and to operate the trust in such a way that:
 
  (a) it will not be deemed to be an "investment company" required to be
      registered under the Investment Company Act;
 
  (b) it will be classified as a grantor trust for United States federal
      income tax purposes; and
 
  (c) the subordinated debt securities held by it will be treated as
      indebtedness of Sempra Energy for United States federal income tax
      purposes.
 
  Sempra Energy and the regular trustees of a trust are authorized to take any
action (so long as it is consistent with applicable law or the applicable
certificate of trust or Declaration) that Sempra Energy and the regular
trustees of the trust determine to be necessary or desirable for such purposes.

  Registered holders of preferred securities have no preemptive or similar
rights.

                 DESCRIPTION OF PREFERRED SECURITIES GUARANTEES
 
General
 
  Sempra Energy will execute a preferred securities guarantee, which benefits
the holders of preferred securities, at the time that a trust issues those
preferred securities. Each preferred securities guarantee will be qualified as
an indenture under the Trust Indenture Act. The Bank of New York will act as
indenture trustee ("preferred securities guarantee trustee") under each
preferred securities guarantee for the purposes of compliance with the Trust
Indenture Act.
 
  The preferred securities guarantee trustee will hold each preferred
securities guarantee for the benefit of the preferred securities holders of the
applicable trust.
 
  Sempra Energy will irrevocably agree, as described in each preferred
securities guarantee, to pay in full, to the holders of the preferred
securities issued by the applicable trust, the preferred securities guarantee
payments (as defined below) (except to the extent previously paid), when and as
due, regardless of any defense, right of set-off or counterclaim which the
trust may have or assert. The following payments, to the extent not paid by a
trust ("preferred securities guarantee payments"), will be covered by the
applicable preferred securities guarantee:
 
    (a) any accrued and unpaid distributions required to be paid on the
  applicable preferred securities, to the extent that the trust has funds
  available to make the payment;
 
    (b) the redemption price, to the extent that the trust has funds
  available to make the payment; and
 
    (c) upon a voluntary or involuntary dissolution and liquidation of the
  trust (other than in connection with a distribution of subordinated debt
  securities to holders of the preferred securities or the redemption of all
  the preferred securities), the lesser of:
 
      (1) the aggregate of the liquidation amount specified in the
    prospectus supplement for each preferred security plus all accrued and
    unpaid distributions on the preferred security to the date of payment,
    to the extent the trust has funds available to make the payment; and
 
      (2) the amount of assets of the trust remaining available for
    distribution to holders of its preferred securities upon a dissolution
    and liquidation of the trust.
 
  Sempra Energy's obligation to make a preferred securities guarantee payment
may be satisfied by directly paying the required amounts to the holders of the
preferred securities or by causing the trust to pay the amounts to the holders.
 
  No single document executed by Sempra Energy relating to the issuance of
preferred securities will provide for its full, irrevocable and unconditional
guarantee of the preferred securities. It is only the combined operation of
Sempra Energy's obligations under the subordinated indenture, the subordinated
debt securities and the applicable preferred securities guarantee and
Declaration that has the effect of providing a full, irrevocable and
unconditional guarantee of a trust's obligations under its preferred
securities.
 
                                       30
<PAGE>
 
Status of the Preferred Securities Guarantees
 
  Each preferred securities guarantee will constitute an unsecured obligation
of Sempra Energy and will rank:
 
    (a) subordinate and junior in right of payment to all of Sempra Energy's
  other liabilities (except any guarantee now or hereafter issued by Sempra
  Energy in respect of any preferred or preference stock of any of its
  affiliates);
 
    (b) equal with any guarantee now or hereafter issued by Sempra Energy in
  respect of the most senior preferred or preference stock now or hereafter
  issued by Sempra Energy, and with any guarantee now or hereafter issued by
  it in respect of any preferred or preference stock of any of its
  affiliates; and
 
    (c) senior to Sempra Energy's common stock.
 
  Each Declaration will require that the holder of preferred securities accept
the subordination provisions and other terms of the preferred securities
guarantee. Each preferred securities guarantee will constitute a guarantee of
payment and not of collection (in other words the holder of the guaranteed
security may sue Sempra Energy, or seek other remedies, to enforce its rights
under the preferred securities guarantee without first suing any other person
or entity). A preferred securities guarantee will not be discharged except by
payment of the preferred securities guarantee payments in full to the extent
not previously paid or upon distribution to the applicable preferred securities
holders of the corresponding series of subordinated debt securities pursuant to
the appropriate Declaration.
 
Amendments and Assignment
 
  Except with respect to any changes which do not adversely affect the rights
of holders of a series of preferred securities in any material respect (in
which case no consent of the holders will be required), a preferred securities
guarantee may be amended only with the prior approval of the holders of at
least a majority in aggregate liquidation amount of the preferred securities
(excluding any the preferred securities held by Sempra Energy or any of its
affiliates). A description of the way to obtain any approval is described under
"Description of the Preferred Securities--Voting Rights; Amendment of
Declarations." All guarantees and agreements contained in a preferred
securities guarantee will be binding on Sempra Energy's successors, assigns,
receivers, trustees and representatives and are for the benefit of the holders
of the applicable preferred securities.
 
Preferred Securities Guarantee Events of Default
 
  An event of default under a preferred securities guarantee occurs if Sempra
Energy fails to make any of its required payments or perform its obligations
under the preferred securities guarantee.
 
  The holders of at least a majority in aggregate liquidation amount of the
preferred securities relating to each preferred securities guarantee (excluding
any preferred securities held by Sempra Energy or any of its affiliates) will
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the preferred securities guarantee
trustee relating to the preferred securities guarantee or to direct the
exercise of any trust or power given to the preferred securities guarantee
trustee under the preferred securities guarantee.
 
                                       31
<PAGE>
 
Information Concerning the Preferred Securities Guarantee Trustees
 
  The preferred securities guarantee trustee under a preferred securities
guarantee, other than during the occurrence and continuance of a default under
the preferred securities guarantee, will perform only the duties that are
specifically described in the preferred securities guarantee. After such a
default, the preferred securities guarantee trustee will exercise the same
degree of care and skill as a prudent person would exercise or use in the
conduct of his or her own affairs. Subject to this provision, a preferred
securities guarantee trustee is under no obligation to exercise any of its
powers as described in the applicable preferred securities guarantee at the
request of any holder of covered preferred securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that it might
incur.
 
Termination of the Preferred Securities Guarantees
 
  Each preferred securities guarantee will terminate once the applicable
preferred securities are paid in full or upon distribution of the corresponding
series of subordinated debt securities to the holders of the preferred
securities. Each preferred securities guarantee will continue to be effective
or will be reinstated if at any time any holder of preferred securities issued
by the applicable trust must restore payment of any sums paid under the
preferred securities or the preferred securities guarantee.
 
Governing Law
 
  The preferred securities guarantees will be governed by and construed in
accordance with the laws of the State of New York.
 
Relationship Among Preferred Securities, Preferred Securities Guarantees and
Subordinated Debt Securities Held By Each Trust
 
  Payments of distributions and redemption and liquidation payments due on each
series of preferred securities (to the extent the applicable trust has funds
available for the payments) will be guaranteed by Sempra Energy to the extent
described under "Description of the Preferred Securities Guarantees." No single
document executed by Sempra Energy in connection with the issuance of any
series of preferred securities will provide for its full, irrevocable and
unconditional guarantee of the preferred securities. It is only the combined
operation of Sempra Energy's obligations under the applicable preferred
securities guarantee, Declaration, subordinated indenture and subordinated debt
securities that has the effect of providing a full, irrevocable and
unconditional guarantee of a trust's obligations under its preferred
securities.
 
  As long as Sempra Energy makes payments of interest and other payments when
due on the subordinated debt securities held by a trust, the payments will be
sufficient to cover the payment of distributions and redemption and liquidation
payments due on the preferred securities issued by that trust, primarily
because:
 
    (a) the aggregate principal amount of the subordinated debt securities
  will be equal to the sum of the aggregate liquidation amount of the
  preferred and common securities;
 
    (b) the interest rate and interest and other payment dates on the
  subordinated debt securities will match the distribution rate and
  distribution and other payment dates for the preferred securities;
 
                                       32
<PAGE>
 
    (c) Sempra Energy shall pay for any and all costs, expenses and
  liabilities of each trust except the trust's obligations under its
  preferred securities (and Sempra Energy has agreed to guarantee such
  payment); and
 
    (d) each Declaration provides that the related trust will not engage in
  any activity that is not consistent with the limited purposes of the trust.
 
  If and to the extent that Sempra Energy does not make payments on the
subordinated debt securities, the trust will not have funds available to make
payments of distributions or other amounts due on its preferred securities. In
those circumstances, you will not be able to rely upon the preferred securities
guarantee for payment of these amounts. Instead, you may directly sue Sempra
Energy or seek other remedies to collect your pro rata share of payments owed.
If you sue Sempra Energy to collect payment, then Sempra Energy will assume
your rights as a holder of preferred securities under the trust's Declaration
to the extent Sempra Energy makes a payment to you in any legal action.
 
  A holder of any preferred security may sue Sempra Energy, or seek other
remedies, to enforce its rights under the applicable preferred securities
guarantee without first suing the applicable preferred securities guarantee
trustee, the trust which issued the preferred security or any other person or
entity.

Energy will pass upon the validity of the securities and the guarantees.
Richards, Layton & Finger, P.A., special Delaware counsel to Sempra Energy and
the trusts, will pass upon certain matters of Delaware law relating to the
validity of the preferred securities. Latham & Watkins, Los Angeles, will pass

agents.
 
                              PLAN OF DISTRIBUTION
 
  We may sell the securities described in this prospectus from time to time in
one or more transactions
 
    (a) to purchasers directly;
 
    (b) to underwriters for public offering and sale by them;
 
    (c) through agents;
 
    (d) through dealers; or
 
                                       33
<PAGE>
 
    (e) through a combination of any of the foregoing methods of sale.
 
  We may distribute the securities from time to time in one or more
transactions at:
 
    (a) a fixed price or prices, which may be changed;
 
    (b) market prices prevailing at the time of sale;
 
    (c) prices related to such prevailing market prices; or
 
    (d) negotiated prices.
 
 Direct Sales
 
  We may sell the securities directly to institutional investors or others who
may be deemed to be underwriters within the meaning of the Securities Act with
respect to any resale of the securities. A prospectus supplement will describe
the terms of any sale of securities we are offering hereunder.
 
 To Underwriters
 
  The applicable prospectus supplement will name any underwriter involved in a
sale of securities. Underwriters may offer and sell securities at a fixed price
or prices, which may be changed, or from time to time at market prices or at
negotiated prices. Underwriters may be deemed to have received compensation
from us from sales of securities in the form of underwriting discounts or
commissions and may also receive commissions from purchasers of securities for
whom they may act as agent. Credit Suisse First Boston Corporation, Goldman,
Sachs & Co., Merrill Lynch & Co., Morgan Stanley Dean Witter and Salomon Smith
Barney Inc. may be involved in any at the market offering of equity securities
by or on our behalf.
 
  Underwriters may sell securities to or through dealers, and such dealers may
receive compensation in the form of discounts, concessions or commissions from
the underwriters and/or commissions (which may be changed from time to time)
from the purchasers for whom they may act as agent.
 
  Unless otherwise provided in a prospectus supplement, the obligations of any
underwriters to purchase securities will be subject to certain conditions
precedent, and the underwriters will be obligated to purchase all the
securities if any are purchased.
 
 Through Agents and Dealers
 
  We will name any agent involved in a sale of securities, as well as any
commissions payable by us to such agent, in a prospectus supplement. Unless we
indicate differently in the prospectus supplement, any such agent will be
acting on a reasonable efforts basis for the period of its appointment.
 
  If we utilize a dealer in the sale of the securities being offered pursuant
to their prospectus, we will sell the securities to the dealer, as principal.
The dealer may then resell the securities to the public at varying prices to be
determined by the dealer at the time of resale.
 
                                       34
<PAGE>
 
 Delayed Delivery Contracts
 
  If we so specify in the applicable prospectus supplement, we will authorize
underwriters, dealers and agents to solicit offers by certain institutions to
purchase the securities pursuant to contracts providing for payment and
delivery on future dates. Such contracts will be subject to only those
conditions set forth in the applicable Prospectus Supplement.
 
  The underwriters, dealers and agents will not be responsible for the validity
or performance of the contracts. We will set forth in the prospectus supplement
relating to the contracts the price to be paid for the securities, the
commissions payable for solicitation of the contracts and the date in the
future for delivery of the securities.
 
 General Information
 
  Underwriters, dealers and agents participating in a sale of the securities
may be deemed to be underwriters as defined in the Securities Act, and any
discounts and commissions received by them and any profit realized by them on
resale of the securities may be deemed to be underwriting discounts and
commissions, under the Securities Act. We may have agreements with
underwriters, dealers and agents to indemnify them against certain civil
liabilities, including liabilities under the Securities Act, and to reimburse
them for certain expenses.
 
  Underwriters or agents and their associates may be customers of, engage in
transactions with or perform services for us or our affiliates in the ordinary
course of business.
 
  Unless we indicate differently in a prospectus supplement, we will not list
the securities on any securities exchange. The securities will be a new issue
of securities with no established trading market. Any underwriters that
purchase securities for public offering and sale may make a market in such
securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. We make no assurance
as to the liquidity of or the trading markets for any securities.

Item 15. Indemnification of Officers and Directors.
 
  Section 317 of the Corporations Code of the State of California permits a
corporation to provide indemnification to its directors and officers under
certain circumstances. The Sempra Energy Amended and Restated Articles of
Incorporation and the Amended and Restated Bylaws eliminate the liability of
directors for monetary damages to the fullest extent permissible under
California law and provide that indemnification for liability for monetary
damages incurred by directors, officers and other agents of Sempra Energy shall
be allowed, subject to certain limitations, in excess of the indemnification
otherwise permissible under California law. In addition, Sempra Energy and
Sempra Energy Holdings have indemnification agreements with each of their
officers and directors that provide for indemnification for monetary damages to
the fullest extent permissible under California law. Sempra Energy and Sempra
Energy Holdings maintain liability insurance and are also insured against loss
for which they may be required or permitted by law to indemnify their directors
and officers for their related acts.
 
  The directors and officers of Sempra Energy and Sempra Energy Holdings are
covered by insurance policies indemnifying them against certain liabilities,
including certain liabilities arising under the Securities Act, which might be
incurred by them in such capacities and against which they cannot be
indemnified by Sempra Energy or Sempra Energy Holdings.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the registrant
pursuant to the foregoing provisions, the registrant has been informed that in
the opinion of the SEC such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

*To be filed by amendment or incorporated by reference in connection with the
offering of the securities.
 
Item 17. Undertakings.
 
  The undersigned registrants hereby undertake:
 
  (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
 
    (i) to include any prospectus required by Section 10(a)(3) of the
  Securities Act;
 
    (ii) to reflect in the prospectus any facts or events arising after the
  effective dated of the Registration Statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Securities and
  Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
  changes in volume and price represent no more than a 20% change in the
  maximum aggregate offering price set forth in the "Calculation of
  Registration Fee" table in the effective Registration Statement; and
 
    (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in the Registration Statement or any
  material change to such information in the Registration Statement;
 
provided, however, that (i) and (ii) do not apply if the information required
to be included in a post-effective amendment by those paragraphs is contained
in periodic reports filed with or furnished to the Securities and Exchange
Commission by the registrants pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.
 
                                      II-3
<PAGE>
 
  (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
  (3) To remove from registration by means of post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
  (4) That, for purposes of determining any liability under the Securities Act,
each filing of Sempra Energy's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
  (5) To file an application for the purpose of determining the eligibility of
the trustees to act under subsection (a) of Section 310 of the Trust Indenture
Act in accordance with the rules and regulations prescribed by the Securities
and Exchange Commission under Section 305(b)(2) of the Securities Act.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrants pursuant to the provisions described under Item 15 above, or
otherwise, the registrants have been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by a registrant of expenses incurred or paid by a director, officer
or controlling person in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, such registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                             WINE ACQUISITION INC.

                                  ARTICLE I.

                                    PURPOSE

          The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of California (the "General Corporation Law"), other than the
banking business, the trust company business or the practice of a profession
permitted to be incorporated by the California Corporations Code.

                                  ARTICLE III.

                                 CAPITAL STOCK

                                   DIRECTORS

          1.   The exact number of directors comprising the entire Board shall
be fixed from time to time by a bylaw or amendment thereof duly adopted by the
Board or approved by not less than two-thirds of the outstanding shares.

          2.   The Board of Directors shall be divided into three classes,
designated Class I, Class II and Class III, as nearly equal in number as

annual meeting of shareholders, but in all cases continue as to each director
until his or her successor shall be elected and shall qualify or until his or
her earlier resignation, removal from office, death or incapacity.  Additional
directorships resulting from an increase in number of directors shall be
apportioned among the classes as equally as possible.  The initial terms of
office shall be determined by resolution duly adopted by

the Board. At each annual meeting of shareholders the number of directors equal
to the number of directors of the class whose term expires at the time of such
meeting (or, if fewer, the number of directors properly nominated and qualified
for election) shall be elected to hold office until the third succeeding annual
meeting of shareholders after their election. This paragraph 2 of this Article
IV shall become effective only when the Corporation becomes a "listed
corporation" within the meaning of (S) 301.5 of the General Corporation Law and

          Unless the Board of Directors, by a resolution adopted by two-thirds
of the authorized number of directors, waives the provisions of this Article VI
in any particular circumstance, any action required or permitted to be taken by
shareholders of the Corporation must be taken either (i) at a duly called annual
or special meeting of shareholders of the Corporation or (ii) by the unanimous
written consent of all of the shareholders.

                                 ARTICLE VII.

       LIABILITY OF DIRECTORS FOR MONETARY DAMAGES; INDEMNIFICATION OF 
                      AND INSURANCE FOR CORPORATE AGENTS

incurred by the agent in that capacity or arising out of the agent's status as

Corporation and who are free 

                                       4
<PAGE>
 
from any relationship that, in the opinion of the Board, would interfere with
the exercise of independent judgment as committee members. The Audit Committee
shall review and make recommendations to the Board with respect to:

Corporation's financial statements and the terms of such engagement;

its members as it shall deem desirable, and, within the limitations specified
for the Executive Committee, may vest such committees with such powers and
authorities as it shall see fit, and all such committees shall at all times be
subject to its control.

          4.   Notice of Meetings.  Notice of each meeting of any committee of
the Board shall be given to each member of such committee, and the giving of
such notice shall be subject of the same requirements as the giving of notice of
meetings of the Board, unless the Board shall establish different requirements
for the giving of notice of committee meetings.

          5.   Conduct of Meetings.  The provisions of these bylaws with respect
to the conduct of meetings of the Board shall govern the conduct of committee
meetings.  Written minutes shall be kept of all committee meetings.

                                  ARTICLE V.

                             SHAREHOLDER MEETINGS

          1.   Annual Meeting.  (a) An Annual Meeting of Shareholders shall be
held each year on such date and at such time as may be designated by resolution
of the Board.

          (b) At an Annual Meeting of Shareholders, only such business shall be
conducted as shall have been properly brought before the Annual Meeting.  To be
properly brought before Annual Meeting, business must be (i) specified in the
notice of the Annual Meeting (or any supplement thereto) given by or at the
direction of the Board and (ii) otherwise properly brought before an Annual
Meeting by a Shareholder.  For business to be properly brought before an Annual
Meeting by a Shareholder, including the nomination of any person 

                                       5
<PAGE>
 
(other than a person nominated by or at the direction of the Board) for election
to the Board, the Shareholder must have given timely and proper written notice
to the Secretary of the Corporation. To be timely, the Shareholder's written
notice must be received at the principal executive office of the Corporation not
less than 60 nor more than 120 in advance of the date corresponding to the date
of the last Annual Meeting of Shareholders; provided, however, that in the event
the Annual Meeting to which the Shareholder's written notice relates is to be
held on a date that differs by more than 60 days from the date of the last
Annual Meeting of Shareholders, the Shareholder's written notice to be timely
must be so received not later than the close of business on the tenth day
following the date on which public disclosure of the date of the Annual Meeting
is made or given to Shareholders. To be proper, the Shareholder's written notice
must set forth as to each matter the Shareholder proposes to bring before the
Annual Meeting (w) a brief description of the business desired to be brought
before the Annual Meeting, (x) the name and address of the Shareholder as they
appear on the Corporation's books, (y) the class and number of shares of the
Corporation that are beneficially owned by the Shareholder and (z) any material
interest of the Shareholder in such business. In addition, if the Shareholder's
written notice relates to the nomination at the Annual Meeting of any person for
election to the Board, such notice to be proper must also set forth (A) the
name, age, business address and residence address of each person to be so
nominated, (B) the principal occupation or employment of each such person, (C)
the number of shares of capital stock of the Corporation beneficially owned by
each such person and (D) such other information concerning each such person as
would be required under the rules of the Securities and Exchange Commission in a
proxy statement soliciting proxies for the election of such person as a
Director, and must be accompanied by a consent, signed by each such person, to
serve as a Director of the Corporation if elected. Notwithstanding anything in
the Bylaws to the contrary, no business shall be conducted at an Annual Meeting
except in accordance with the procedures set forth in this Section l(b) of
Article V.

          2.   Special Meetings.  Special meetings of the Shareholders for any
purpose whatsoever may be called at any time by the Chairman, the Vice Chairman,
the President, or the Board, or by one or more Shareholders holding not less
than one-tenth of the voting power of the Corporation.  Within five business
days after receiving such a written request from Shareholders of the
corporation, the Board shall determine whether Shareholders owning not less than
one-tenth of the voting power of the Corporation support the call of a special
meeting and notify the requesting party or parties of its finding.

          3.   Place of Meetings.  All meetings of the Shareholders shall be
held at the principal office of the Corporation in [San Diego], California, or
at such other locations as may be designated by the Board.

          4.   Notice of Meetings.  Written notice shall be given to each
Shareholder entitled to vote of the date, time, place and general purpose of
each meeting of Shareholders.  Notice may be given personally, or by mail, or by
telegram, charges prepaid, to the Shareholder's address appearing on the books
of the Corporation.  If a Shareholder supplies no address to the Corporation,
notice shall be deemed to be given if mailed to the place where the principal
office of the Corporation is situated or published at least once in some
newspaper of general circulation 

                                       6
<PAGE>
 
in the county of said principal office. Notice of any meeting shall be sent to
each Shareholder entitled thereto not less thin 10 or more than 60 days before
such meeting.

          5.   Voting.  The Board may fix a time in the future not less than 10
or more than 60 days preceding the date of any meeting of Shareholders, or not
more than 60 days preceding the date fixed for the payment of any dividend or
distribution, or for the allotment of rights, or when any change or conversion
or exchange of shares shall go into effect, as a record date for the
determination of the Shareholders entitled to notice of and to vote at any such
meeting or entitled to receive any such dividend or distribution, or any such
allotment of rights, or to exercise the rights in respect to any such change,
conversion, or exchange of shares.  In such case only Shareholders of record at
the close of business on the date so fixed shall be entitled to notice of and to
vote at such meeting or to receive such dividend, distribution or allotment of
rights, or to exercise such rights, as the case may be, notwithstanding any
transfer of any shares on the books of the Corporation after any record date
fixed as aforesaid.  The Board may close the books of the Corporation against
any transfer of shares during the whole or any part of such period.

          6.   Quorum.  At any Shareholders' meeting a majority of the shares
entitled to vote must be represented in order to constitute a quorum for the
transaction of business, but a majority of the shares present, or represented by
proxy, though less than a quorum, may adjourn the meeting to some other date,
and from day to day or from time to time thereafter until a quorum is present.

          7.   Confidential Voting.  Each Shareholder of the Corporation shall
be entitled to elect voting confidentiality as provided in this Section 7 on all
matters submitted to Shareholders by the Board and each form of proxy, consent,
ballot or other written voting instruction distributed by the Shareholders shall
include a check box or other appropriate mechanism by which Shareholders who
desire to do so may so elect voting confidentiality.  All inspectors of
election, vote tabulators and other persons appointed or engaged by or on behalf
of the process voting instructions (none of whom shall be a Director or officer
of the Corporation or any of its affiliates) shall be advised of and instructed
to comply with this Section 7 and, except as required or permitted hereby, not
at any time to disclose to any person (except to other persons engaged in
processing voting instructions), the identity and individual vote of any
Shareholder electing voting confidentiality; provided, however, that voting
confidentiality shall not apply and the name and individual vote of any
Shareholder may be disclosed to the Corporation or to any person (i) to the
extent that such disclosure is required by applicable law or is appropriate to
assert or defend any claim relating to voting or (ii) with respect to any matter
for which votes of Shareholders are solicited in opposition to any of the
nominees or the recommendations of the Board unless the persons engaged in such
opposition solicitation provide Shareholders of the Corporation with voting
confidentiality (which, if not otherwise provided, will be requested by the
Corporation) comparable in the opinion of the Corporation to the voting
confidentiality provided by this Section 7.

                                  ARTICLE VI.

                             CERTIFICATE OF SHARES

          1.   Form.  Certificates for shares of the Corporation shall state the
name of the registered holder of the shares represented thereby, and shall be
signed by the Chairman, the Vice Chairman, the President or a Vice President and
by the Secretary or an Assistant Secretary.  Any such signature may be by
facsimile thereof.

          2.   Surrender.  Upon a surrender to the Secretary, or to a transfer
agent or transfer clerk of the Corporation, of a certificate for shares duly
endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, the Corporation shall issue a new certificate to the
party entitled thereto, cancel the old certificate and record the transaction
upon its books.

          3.   Right of Transfer.  When a transfer of shares on the books is
requested, and there is a reasonable doubt as to the rights of the persons
seeking such transfer, the Corporation, or its transfer agent or transfer clerk,
before entering the transfer of the shares on its books or issuing any
certificate therefor, may require from such person reasonable proof of his or
her rights, and, if there remains a reasonable doubt in respect thereto, may
refuse a transfer unless such person shall give adequate security or a bond of
indemnity executed by a corporate surety, or by two individual sureties,
satisfactory to the Corporation as to form, amount and responsibility of
sureties.

          4.   Conflicting Claims.  The Corporation shall be entitled to treat
the holder of record of any shares as the holder in fact thereof and shall not
be bound to recognize any equitable or other claim to or interest in such shares
on the part of any other person, whether or not it shall have express or other
notice thereof, save as expressly provided by the laws of the State of
California.

          5.   Loss Theft and Destruction.  In the case of the alleged loss,
theft or destruction of any certificate of shares, another may be issued in its
place as follows:  (1) the owner of the lost, stolen or destroyed certificate
shall file with the transfer agent of the Corporation a duly executed Affidavit
or Loss and Indemnity Agreement and Certificate of Coverage, accompanied by a
check representing the cost of the bond as outlined in any blanket lost
securities and avoid administration bond previously approved by the Directors of
the Corporation and executed by a surety company satisfactory to them, which
bond shall indemnify the Corporation, its transfer agents and registrars; or (2)
the Board may, in its discretion, authorize the issuance of a new certificate to
replace a lost, stolen or destroyed certificate on such other terms and
conditions as it may determine to be reasonable.

                                 ARTICLE VII.

                      INDEMNIFICATION OF CORPORATE AGENTS

          1.   Definitions.  For the purposes of this Article VII, "agent" means
any person who (i) is or was a Director, officer, employee or other agent of the
Corporation, (ii) is or was serving at the request of the Corporation as a
director, officer, employee or agent of another foreign or domestic corporation,
partnership, joint venture, trust or other enterprise or (iii) was a director,
officer, employee or agent of a foreign or domestic corporation which was a
predecessor corporation of the Corporation or of another enterprise at the
request of such predecessor corporation; "proceeding" means any threatened,
pending or completed action or proceeding, whether civil, criminal,
administrative or investigative; and "expenses" includes, without limitation,
attorneys' fees and any expenses of establishing a right to indemnification
under Sections 4 or 5(c) of this Article VII.

          2.   Indemnification for Third Party Actions.  The Corporation shall
indemnify any person who is or was a party, or is threatened to be made a party,
to any proceeding (other than an action by or in the right of the Corporation to
procure a judgment in its favor) by reason of the fact that such person is or
was an agent of the Corporation against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred in connection with such
proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in the best interests of the Corporation and, in the
case of a criminal proceeding, had no reasonable cause to believe the conduct of
such person was unlawful.  The termination of any proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that the person did not act in good faith
and in a manner which the person reasonably believed to be in the best interests
of the Corporation or that the person had reasonable cause to believe that the
person's conduct was unlawful.

          3.   Indemnification for Derivative Actions.  The Corporation shall
indemnify any person who is or was a party, or is threatened to be made a party,
to any threatened, pending or completed action by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that such
person is or was an agent of the Corporation against expenses actually and
reasonably incurred by such person in connection with the defense or settlement
of such action if such person acted in good faith and in a manner such person
believed to be in the best interests of the Corporation and its Shareholders.
No indemnification shall be made under this Section 3 (a) in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation in the performance of such person's duty to the
Corporation and its Shareholders, unless and only to the extent that the court
in which such proceeding is or was pending shall determine upon application
that, in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for expenses and then only to the extent that
the court shall determine; (b) of amounts paid in settling or otherwise
disposing of a pending action without court approval; or (c) of expenses
incurred in defending a pending action which is settled or otherwise disposed of
without court approval.

                                       9
<PAGE>
 
          4.   Successful Defense.  Notwithstanding any other provision of this
Article, to the extent that an agent of the Corporation has been successful on
the merits or otherwise (including the dismissal of an action without prejudice
or the settlement of a proceeding or action without admission of liability) in
defense of any proceeding referred to in Sections 2 or 3 of this Article, or in
defense of any claim, issue or matter therein, the agent shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred in
connection therewith.

          5.   Discretionary Indemnification.  Except as provided in Section 4
of this Article VII, any indemnification under Section 3 hereof shall be made by
the Corporation only if authorized in the specific case, upon a determination
that indemnification of the agent is proper in the circumstances because the
agent has met the applicable standard of conduct set forth in Section 2 or 3, by
(a) a majority vote of a quorum consisting of Directors who are not parties to
such proceeding; (b) if such a quorum of Directors is not obtainable, by
independent legal counsel in a written opinion; (c) approval by the affirmative
vote of a majority of the shares of this Corporation represented and voting at a
duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum) or by
the written consent of holders of a majority of the outstanding shares which
would be entitled to vote at such meeting and, for such purpose, the shares
owned by the person to be indemnified shall not be considered outstanding or
entitled to vote; or (d) the court in which such proceeding is or was pending,
upon application made by the Corporation, the agent or the attorney or other
person rendering services in connection with the defense, whether or not such
application by said agent, attorney or other person is opposed by the
Corporation.

          6.   Advancement of Expenses.  Expenses incurred in defending any
proceeding may be advanced by the Corporation prior to the final disposition of
such proceeding upon receipt of an undertaking by or on behalf of the agent to
repay such amount if it shall be determined ultimately that the agent is not
entitled to be indemnified as authorized in this Article VII.

          7.   Restriction on Indemnification.  No indemnification or advance
shall be made under this Article VII, except as provided in Sections 4 and 6
hereof, in any circumstance where it appears that it would be inconsistent with
(a) a provision of the articles of incorporation of the Corporation, its bylaws,
a resolution of the Shareholders or an agreement in effect at the time of the
accrual of the alleged cause of action asserted in the proceeding in which the
expenses were incurred or other amounts were paid which prohibits or otherwise
limits indemnification; or (b) any condition expressly imposed by a court in
approving a settlement.

          8.   Non-Exclusive.  The indemnification provided by this Article VII
shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any statute, bylaw, agreement, vote of
Shareholders or disinterested Directors or otherwise, both as to action in an
official capacity and as to action in another capacity while holding such
office.  The rights to indemnification under this Article VII shall continue as
to a person who has ceased to be a Director, officer, employee, or agent and
shall inure to the benefit of the heirs, executors, and administrators of the
person.  Nothing contained in this Section 8 shall affect any 

                                       10
<PAGE>
 
right to indemnification to which persons other than such Directors and officers
may be entitled by contract or otherwise.

          9.   Expenses as a Witness.  To the extent that any agent of the
Corporation is by reason of such position, or a position with another entity at
the request of the Corporation, a witness in any action, suit or proceeding, he
or she shall be indemnified against all costs and expenses actually and
reasonably incurred by him or her or on his or her behalf in connection
therewith.

          10.  Insurance.  The Corporation may purchase and maintain directors
and officers liability insurance, at its expense, to protect itself and any
Director, officer or other named or specified agent of the Corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss asserted against or incurred by the agent
in such capacity or arising out of the agent's status as such, whether or not
the Corporation would have the power to indemnify the agent against such
expense, liability or loss under the provisions of this Article II or under the
General Corporation Law.

          11.  Separability.  Each and every paragraph, sentence, term and
provision of this Article VII is separate and distinct so that if any paragraph,
sentence, term or provision hereof shall be held to be invalid or unenforceable
for any reason, such invalidity or unenforceability shall not affect the
validity or unenforceability of any other paragraph, sentence, term or provision
hereof.  To the extent required, any paragraph, sentence, term or provision of
this Article may be modified by a court of competent jurisdiction to preserve
its validity and to provide the claimant with, subject to the limitations set
forth in this Article and any agreement between the Corporation and claimant,
the broadest possible indemnification permitted under applicable law.  If this
Article VII or any portion hereof shall be invalidated on any ground by any
court of competent jurisdiction, then the Corporation shall nevertheless have
the power to indemnify each Director, officer, employee, or other agent against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement with respect to any action, suit, proceeding or investigation,
whether civil, criminal or administrative, and whether internal or external,
including a grand jury proceeding and including an action or suit brought by or
in the right of the Corporation, to the full extent permitted by any applicable
portion of this Article VII that shall not have been invalidated or by any other
applicable law.

          12.  Agreements.  Upon, and in the event of, a determination of the
Board to do so, the Corporation is authorized to enter into indemnification
agreements with any or all of its Directors, officers, employees and other
agents providing for indemnification to the fullest extent permissible under
California law and the Corporation's articles of incorporation.

          13.  Retroactive Appeal.  In the event this Article VII is repealed or
modified so as to reduce the protection afforded herein, the indemnification
provided by this Article VII shall remain in full force and effect with respect
to any act or omission occurring prior to such repeal or modification.

Section 102.  Compliance Certificates and Opinions.

     Upon any application or request by the Corporation to the Trustee to take
any action under any provision of this Indenture, the Corporation shall furnish
to the Trustee such certificates and opinions as may be required under the Trust
Indenture Act.  Each such certificate or opinion shall be given in the form of
an Officers' Certificate, if to be given by an officer of the Corporation, or an
Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in
this Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include

          (1) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions herein
     relating thereto;

Section 103.  Form of Documents Delivered to Trustee.
              --------------------------------------

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an officer of the Corporation may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such officer's certificate or opinion is
based are erroneous.  Any such certificate or opinion of counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Corporation stating that the
information with respect to such factual matters is in

                                       7
<PAGE>
 
the possession of the Corporation, unless such counsel knows, or in the exercise
of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Whenever, subsequent to the receipt by the Trustee of any Board Resolution,
Officers' Certificate, Opinion of Counsel or other document or instrument, a
clerical, typographical or other inadvertent or unintentional error or omission
shall be discovered therein, a new document or instrument may be substituted
therefor in corrected form with the same force and effect as if originally filed
in the corrected form and, irrespective of the date or dates of the actual
execution and/or delivery thereof, such substitute document or instrument shall
be deemed to have been executed and/or delivered as of the date or dates
required with respect to the document or instrument for which it is substituted.
Anything in this Indenture to the contrary notwithstanding, if any such
corrective document or instrument indicates that action has been taken by or at
the request of the Corporation which could not have been taken had the original
document or instrument not contained such error or omission, the action so taken
shall not be invalidated or otherwise rendered ineffective but shall be and
remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith.  Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

Section 104.  Acts of Holders; Record Dates.
              -----------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by 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 Corporation.
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 Corporation, if made in the manner provided in this Section.

     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof.  Where such execution is
by a signer acting in a capacity other than the signer's individual capacity,
such

                                       8
<PAGE>
 
certificate or affidavit shall also constitute sufficient proof of the signer's
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

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

     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 Corporation
in reliance thereon, whether or not notation of such action is made upon such
Security.

     The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series; provided that the
Corporation may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke the relevant action, whether or not such
Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date.  Nothing in this paragraph shall
be construed to prevent the Corporation from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken.  Promptly after any record date is set
pursuant to this paragraph, the Corporation, at its own expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record

                                       9
<PAGE>
 
date. Nothing in this paragraph shall be construed to prevent the Trustee from
setting a new record date for any action for which a record date has previously
been set pursuant to this paragraph (whereupon the record date previously set
shall automatically and with no action by any Person be canceled and of no
effect), and nothing in this paragraph shall be construed to render ineffective
any action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be sent to the
Corporation in writing and to each Holder of Securities of the relevant series
in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date.  If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.  Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such 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 principal amount.

Section 105.  Notices, Etc., to Trustee and Corporation.
              -----------------------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders 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 Corporation shall be
     sufficient for every purpose hereunder if made, given, furnished or filed
     in writing (which may be made via facsimile) to or with the Trustee at its
     Corporate Trust Office, Attention: Global Agency and Trust Services, or

          (2) the Corporation 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
     Corporation addressed to it at the address of its principal office
     specified in the first paragraph of this instrument, Attention:  Treasurer,
     or at any other address previously furnished in writing to the Trustee by
     the Corporation.

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 his address as it appears in the Security 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 any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other 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 which 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
which 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.

bind its successors and assigns, whether so expressed or not.

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.

Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity.

     Section 204 and any circumstances in addition to or in lieu of those set
     forth in Clause (2) of the last paragraph of Section 305 in which any such
     Global Security may be exchanged in whole or in part for Securities
     registered, and any transfer of such Global Security in whole or in part

     to Section 502;

          (19) any addition to or change in the covenants set forth in Article
     Ten which applies to Securities of the series; and

     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 forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or

                                       21
<PAGE>
 
an Assistant Secretary of the Corporation and delivered to the Trustee at or
prior to the delivery of the Officers' Certificate setting forth the terms or
the manner of determining the terms of the series.

     With respect to Securities of a series offered in a Periodic Offering, the
Board Resolution (or action taken pursuant thereto), Officers' Certificate or
supplemental indenture referred to above may provide general terms or parameters
for Securities of such series and provide either that the specific terms of
particular Securities of such series shall be specified in a Company Order or
that such terms shall be determined by the Corporation in accordance with other
procedures specified in a Company Order as contemplated by the third paragraph
of Section 303.

     Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

Section 302.  Denominations.
              -------------

     The Securities of each series shall be issuable only in fully registered
form without coupons and only in such 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 $1,000 and any integral multiple thereof.

Section 303.  Execution, Authentication, Delivery and Dating.
              ----------------------------------------------

     The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, its President or one of its Vice Presidents, under its corporate seal
reproduced thereon (which may be by facsimile) 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 Corporation shall bind the
Corporation, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Corporation may deliver Securities of any series executed by the
Corporation to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities, provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of electronic instructions from the
Corporation or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order

                                       22
<PAGE>
 
delivered to the Trustee prior to the time of the first authentication of
Securities of such series. 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,

          (1) if the form of such Securities has been established by or pursuant
     to Board Resolution 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, or in the case of
     Securities of a series offered in a Periodic Offering, will be, established
     by or pursuant to Board Resolution as permitted by Section 301, that such
     terms have been, or in the case of Securities of a series offered in a
     Periodic Offering, will be, established in conformity with the provisions
     of this Indenture, subject, in the case of Securities of a series offered
     in a Periodic Offering, to any conditions specified in such Opinion of
     Counsel; and

          (3) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Corporation in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Corporation 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 and 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.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Corporation of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

     Each Security shall be dated the date of its authentication.

                                       23
<PAGE>
 
     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 of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this Indenture such
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

Section 304.  Temporary Securities.
              --------------------

     Pending the preparation of definitive Securities of any series, the
Corporation 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 Corporation 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 the office or agency of the Corporation in a Place of Payment for that
series, without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series, the Corporation shall execute
and the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount.  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 and tenor.

Section 305.  Registration, Registration of Transfer and Exchange.
              ---------------------------------------------------

     The Corporation shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Corporation shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security 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
the office or agency of the Corporation in a Place of Payment for that series,
the Corporation shall execute, and the Trustee shall authenticate and deliver,
in the name of the designated transferee or

                                       24
<PAGE>
 
transferees, one or more new Securities of the same series, of any authorized
denominations and of like tenor and 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 like
tenor and 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 Corporation 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 Corporation, 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 Corporation or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Corporation 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 1106 not involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are
to be redeemed, the Corporation shall not be required (A) 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 selected for redemption and ending at the close of business on
the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

     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

                                       25
<PAGE>
 
     Depositary has notified the Corporation that it is unwilling or unable to
     continue as Depositary for such Global Security and a successor Depositary
     has not been appointed by the Corporation within 90 days of receipt by the
     Corporation of such notification, (B) if at any time the Depositary ceases
     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
     and no successor Depositary shall have been appointed by the Corporation
     within 90 days after it became aware of such cessation, or (C) 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. Notwithstanding the foregoing, the Corporation may at any time
     in its sole discretion determine that Securities issued in the form of a
     Global Security shall no longer be represented in whole or in part by such
     Global Security, and the Trustee, upon receipt of a Company Order therefor,
     shall authenticate and deliver definitive Securities in exchange in whole
     or in part for such Global Security.

          (3) Subject to Clause (2) above, any exchange or transfer of a Global
     Security for other Securities may be made in whole or in part, and all
     Securities issued in exchange for or upon transfer of 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
     1106 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 Corporation
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 Corporation 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
Corporation or the Trustee that such Security has been acquired by a bona fide
purchaser, the Corporation 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 Corporation in its discretion may,
instead of issuing a new Security, pay such Security.

                                       26
<PAGE>
 
     Upon the issuance of any new Security under this Section, the Corporation
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 (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 Corporation, 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.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, 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 Corporation, at
its election in each case, as provided in Clause (1) or (2) below:

          (1) The Corporation 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 Corporation
     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 Corporation 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 Corporation of
     such Special Record Date and, in the name and at the expense of the
     Corporation, shall cause notice of

                                       27
<PAGE>
 
     the proposed payment of such Defaulted Interest and the Special Record Date
     therefor to be given to each Holder of Securities of such series in the
     manner set forth in Section 106, 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 Corporation 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, if any, on which such
     Securities may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Corporation 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 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, which were carried by such other Security.

Section 308.  Persons Deemed Owners.
              ---------------------

     Prior to due presentment of a Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation or the Trustee may
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 any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation 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 or for credit against any sinking fund payment shall, if 
surrendered to any Person other than the Trustee, be delivered to the Trustee 
and shall be promptly canceled by it.  The Corporation may at any time deliver 
to the Trustee for cancellation any Securities previously authenticated and 
delivered hereunder which the Corporation may have acquired in any manner 
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of in its customary manner or
as directed by a Company Order; provided, however, that the Trustee shall not be
required to destroy such canceled Securities.

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.

Section 311.  CUSIP Numbers.

     The Corporation in issuing the Securities 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. The Corporation shall promptly 
notify the Trustee of any change in the "CUSIP" numbers.

               redemption by the Trustee in the name, and at the expense, of the
               Corporation,

          and the Corporation, in the case of (i), (ii) or (iii) above, has
          deposited or caused to be deposited with the Trustee as trust funds in
          trust for the purpose (i) money in an amount, (ii) Government
          Obligations (as defined in Section 1304) which through the scheduled
          payment of principal and interest in respect thereof in accordance
          with their terms will provide, not later than the due date of any
          payment, money in an amount, or (iii) a combination thereof,
          sufficient, in the case of (ii) or (iii), in the opinion of a
          nationally recognized firm of independent public accountants expressed
          in a written certification thereof delivered to the Trustee, to pay
          and discharge, and which shall be applied by the Trustee to pay and
          discharge, the entire indebtedness on such Securities not theretofore
          delivered to the Trustee for cancellation, for principal and any
          premium and interest to the date of such deposit (in the case of
          Securities which have become due and payable) or to the Stated

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

     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent herein provided for relating to the satisfaction and discharge of

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 (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is inapplicable to a particular series or is specifically deleted or
modified in the Board Resolution (or action taken pursuant thereto), Officers'
Certificate or supplemental indenture under which such series of Securities is
issued or has been deleted or modified in an indenture supplemental hereto:

          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 60 days; provided, however, that if the Corporation is
     permitted by the terms of the Securities of such series to defer the
     payment in question, the date on which such payment is due and payable
     shall be the date on which the Corporation is required to make payment
     following such deferral, if such deferral has been elected pursuant to the
     terms of the Securities; or

          (2) default in the payment of the principal of or any premium on any
     Security of that series at its Maturity; or

          (3) default in the making of any sinking fund payment, when and as due
     by the terms of a Security of that series, and continuance of such default
     for a period of 60 days; or

     Corporation in this Indenture (other than a covenant a default in whose
     performance or whose breach is elsewhere in this Section specifically dealt
     with or which has expressly been included in this Indenture solely for the
     benefit of series of Securities other than that series), and continuance of
     such default or breach for a period of 90 days after there has been given,
     by registered or certified mail, to the Corporation by the Trustee or to
     the Corporation and the Trustee by the Holders of at least 25% in principal
     amount of the Outstanding Securities of that series a written notice
     specifying such default or breach and requiring it to be remedied and
     stating that such notice is a "Notice of Default" hereunder, unless the
     Trustee, or the Trustee and the Holders of a principal amount of Securities
     of such series not less than the principal amount of Securities the Holders
     of which gave such notice, as the case may be, shall agree in writing to an
     extension of such period prior to its expiration; provided, however, that
     the Trustee, or the Trustee and the Holders of such principal amount of
     Securities of such series, as the case may be, shall be deemed to have
     agreed to an extension of such period if corrective action is initiated by
     the Corporation within such period and is being diligently pursued; or

                                       31

          (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Corporation in an involuntary
     case or proceeding under any applicable federal or state bankruptcy,
     insolvency, reorganization or other similar law or (B) a decree or order
     adjudging the Corporation a bankrupt or insolvent, or approving as properly
     filed a petition seeking reorganization, arrangement, adjustment or
     composition of or in respect of the Corporation under any applicable
     federal or state law, or appointing a custodian, receiver, liquidator,
     assignee, trustee, sequestrator or other similar official of the
     Corporation or of any substantial part of its property, or ordering the
     winding-up or liquidation of its affairs, and the continuance of any such
     decree or order for relief or any such other decree or order unstayed and
     in effect for a period of 90 consecutive days; or

          (6) the commencement by the Corporation of a voluntary case or
     proceeding under any applicable federal or state bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Corporation in an
     involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or to the
     commencement of any bankruptcy or insolvency case or proceeding against it,
     or the filing by it of a petition or answer or consent seeking
     reorganization or relief under any applicable federal or state law, or the
     consent by it to the filing of such petition or to the appointment of or
     taking possession by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Corporation or of any
     substantial part of its property, or the making by it of an assignment for
     the benefit of creditors, or the admission by it in writing of its
     inability to pay its debts generally as they become due, or the
     authorization of any such action by the Board of Directors; or

          (7) any other Event of Default provided with respect to Securities of
     that series.

Section 502.  Acceleration of Maturity; Rescission and Annulment.
              --------------------------------------------------

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Event of Default giving rise to such declaration of
acceleration shall, without further act, be deemed to have been waived, and such

                                       32
<PAGE>
 
declaration and its consequences shall, without further act, be deemed to have
been rescinded and annulled, if

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

               (A) all overdue interest on all Securities of that series,

               (B) the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration and any interest thereon at the rate or rates
          prescribed therefor in such Securities,

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

               (D) 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 non-payment 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 Corporation covenants that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 60 days, or

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

the Corporation 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

                                       33
<PAGE>
 
     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 effectual 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 relative to the Corporation (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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

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.
              ------------------------------

     Any money 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 any premium
or interest, upon presentation of the Securities

                                       34
<PAGE>
 
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 any premium and 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 any premium and interest,
     respectively; and

          Third:  To the payment of the balance, if any, to the Corporation.

Section 507.  Limitation on Suits.
              -------------------

     No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

          (1) such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;

          (2) the Holders of not less than a majority in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee indemnity
     satisfactory to the Trustee against the costs, expenses and liabilities to
     be incurred in compliance with such request;

          (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;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

Section 508.  Unconditional Right of Holders to Receive Principal, Premium 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 any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities 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 Corporation, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.
              ------------------------------

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the 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 Securities 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, with respect to the Securities of
such series; provided that

                                       36
<PAGE>
 
          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture,

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

          (3) subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability.

Section 513.  Waiver of Past Defaults.
              -----------------------

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

          (1) in the payment of the principal of or any premium or interest on
     any Security of such series, 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 the series affected.

     Upon any such waiver, such default shall cease to exist and be deemed not
to have occurred, and any Event of Default arising therefrom shall be deemed to
have been cured and not to have occurred, 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 suit to
file an undertaking to pay the costs, including legal fees and expenses 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 Corporation or the Trustee.

Section 515.  Waiver of Stay or Extension Laws.
              --------------------------------

     The Corporation 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 Corporation (to the extent that

                                       37
<PAGE>
 
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 VI.

                                  THE TRUSTEE

Section 601.  Certain Duties and Responsibilities.
              -----------------------------------

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act.  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 a 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(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof.  For the
purpose of this Section, the term "default" means any event which is, or after

          (1) to pay to the Trustee from time to time such compensation as shall
     be agreed to in writing between the Corporation and the Trustee for all
     services rendered by it hereunder (which compensation shall not be limited

     express trust);

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

administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section shall survive the termination of this
Indenture.

Section 608.  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.

                                       40
<PAGE>
 
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 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 condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
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 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.
              -------------------------------------------------

     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 the successor Trustee in accordance with the applicable
requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Corporation. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Corporation, any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

     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
Corporation. If an instrument of acceptance by a successor Trustee shall not 
have been delivered to the Trustee within 30 days after the giving of such 
notice of removal, the Trustee being removed may petition, at the expense of the
Corporation, any court of competent jurisdiction for the appointment of a 
successor Trustee with respect to the Securities of such series.

     If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Corporation 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 Corporation 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

                                       41
<PAGE>
 
     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,

then, in any such case, (A) the Corporation by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) 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 himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     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 Corporation, 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) and shall comply with the applicable
requirements of Section 611.  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 Corporation and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Corporation.  If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Corporation or the Holders and accepted appointment in the
manner required by Section 611, 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.

     The Corporation 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 name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

Section 611.  Acceptance of Appointment by Successor.
              --------------------------------------

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

                                       42
<PAGE>
 
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 Corporation, 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
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or 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 Corporation 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 Corporation 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.
              -----------------------------------------------------------

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, 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

                                       43
<PAGE>
 
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.

Section 613.  Preferential Collection of Claims Against Corporation.
              -----------------------------------------------------

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

Section 614.  Appointment of Authenticating Agent.
              -----------------------------------

     The Trustee may appoint an Authenticating Agent or Agents acceptable to the
Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  Wherever reference
is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee's certificate of authentication, such reference shall
be deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Corporation and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority.  If such Authenticating Agent 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, the combined capital
and surplus of such Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent 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 Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided that such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Corporation.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the

                                       44
<PAGE>
 
Corporation. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Corporation and shall give notice of such appointment in the manner provided in
Section 106 to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

     The Corporation agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

Corporation may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date

form reasonably satisfactory to the Trustee, executed and delivered to the
Trustee by the Person (if other than the Corporation) formed by such
consolidation, or into which the Corporation shall have been merged, or by the
Person which shall have acquired such properties and assets, and (ii) the
Corporation shall deliver to the Trustee an Officers' Certificate and an Opinion
of Counsel, each stating that such consolidation, merger, conveyance or transfer
and, if a supplemental indenture is required in connection with such
transaction, such supplemental indenture comply with this Article and that all
conditions precedent herein provided for relating to such transaction have been
complied with.

     Upon any consolidation of the Corporation with, or merger of the
Corporation into, any other Person or any conveyance or transfer of the

consolidation or into which the Corporation is merged or to which such
conveyance or transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Corporation under this Indenture with the
same effect as if such successor Person had been named as the Corporation
herein, and thereafter the predecessor Person shall be relieved of all
obligations and covenants under this Indenture and the Securities.

for any of the following purposes:

          (1) to evidence the succession of another Person to the Corporation
     and the assumption by any such successor of the covenants of the
     Corporation herein and in the Securities; or

          (2) to add to the covenants of the Corporation for the benefit of the
     Holders of all or any series of Securities (and if such covenants are to be
     for the benefit of less than all series of Securities, stating that such
     covenants are expressly being included solely for the benefit of such
     series) or to surrender any right or power herein conferred upon the
     Corporation; or

          (3) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events

     stating that such additional Events of Default are expressly being included
     solely for the benefit of such series); or

          (4) to add to or change any of the provisions of this Indenture to
     such extent as shall be necessary to permit or facilitate the issuance of
     Securities in bearer form, registrable or not registrable as to principal,

     Securities in uncertificated form; or

          (5) to add to, change or eliminate any of the provisions of this
     Indenture in respect of one or more series of Securities; provided that any
     such addition, change or elimination (A) shall neither (i) apply to any
     Security of any series created prior to the execution of such supplemental
     indenture and entitled to the benefit of such provision nor (ii) modify the
     rights of the Holder of any such Security with respect to such provision or
     (B) shall become effective only when there is no such Security Outstanding;
     or

          (6)  to secure the Securities; or

     more series and to 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, pursuant to the requirements

Section 902.  Supplemental Indentures With Consent of Holders.
              -----------------------------------------------

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of all series affected by such supplemental
indenture (voting as one class), by Act of said Holders delivered to the
Corporation and the Trustee, the Corporation, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture, or modifying in any manner the rights of the Holders of
Securities under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security or any other Security which would be due
     and payable upon a declaration of acceleration of the Maturity thereof
     pursuant to Section 502 or change the coin or currency in which any
     Security or any premium or interest thereon is payable, or impair the right
     to institute suit for the enforcement of any such payment on or after the
     Stated Maturity thereof (or, in the case of redemption, on or after the
     Redemption Date), or

          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or

          (3) modify any of the provisions of this Section, Section 513 or
     Section 1006, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1006, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611 and 901(8).  A supplemental indenture which changes or eliminates any
     covenant or other provision of this Indenture which has expressly been
     included solely for the benefit of one or more particular series of
     Securities, or which modifies the rights of the Holders of Securities of
     such series with respect to such covenant or other provision, shall be
     deemed not to affect the rights under this Indenture of the Holders of
     Securities of any other series.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 903.  Execution of Supplemental Indentures.
              ------------------------------------

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel and an Officers' Certificate, each stating that the execution
of such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

Section 904.  Effect of Supplemental Indentures.
              ---------------------------------

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 905.  Conformity with Trust Indenture Act.
              -----------------------------------

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

Section 906.  Reference in Securities to Supplemental Indentures.
              --------------------------------------------------

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Corporation shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Corporation, to any such supplemental indenture
may be prepared and executed by the Corporation and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.

                                  ARTICLE X.

                                   COVENANTS

Section 1001.  Payment of Principal, Premium and Interest.
               ------------------------------------------

     The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

Section 1002.  Maintenance of Office or Agency.
               -------------------------------

     The Corporation will maintain in each Place of Payment for any series of
Securities an office or agency 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 and

                                       50
<PAGE>
 
where notices and demands to or upon the Corporation in respect of the
Securities of that series and this Indenture may be served. The Corporation 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 Corporation 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
Corporation hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Corporation may also from time to time designate one or more other
offices or agencies 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 Corporation of its obligation to maintain an
office or agency in each Place of Payment for Securities of any series for such
purposes.  The Corporation 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 Securities Payments to Be Held in Trust.
               -------------------------------------------------

     If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium 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 and any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium 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 Corporation will promptly notify the Trustee of its action or
failure so to act.

     The Corporation will cause each Paying Agent for any series of Securities
other than the Trustee 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, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Corporation (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 for payment in
respect of the Securities of that series.

     The Corporation 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 hereunder by the Corporation 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
Corporation or such Paying Agent; and, upon such payment by any

                                       51
<PAGE>
 
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 Corporation, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Corporation cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Corporation.

Section 1004.  Corporate Existence.
               -------------------

     Subject to Article Eight, the Corporation will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises. The Corporation shall 
deliver to the Trustee, as soon as possible and in any event within five days 
after the Corporation becomes aware of the occurrence of any Event of Default or
an event which, with notice or the lapse of time or both, would constitute an 
Event of Default, an Officers' Certificate setting forth the details of such 
Event of Default or default and the action which the Corporation proposes to 
take with respect thereto.

Section 1005.  Statement by Officers as to Default.
               -----------------------------------

     The Corporation will deliver to the Trustee, on or before October 15 of
each calendar year or on or before such other day in each calendar year as the
Corporation and the Trustee may from time to time agree upon, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Corporation is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Corporation
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

Section 1006.  Waiver of Certain Covenants.
               ---------------------------

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series, the Corporation may, with respect to the Securities of any
series, omit in any particular instance to comply with any term, provision or
condition set forth in any covenant provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such series if before the time for
such compliance the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of

                                       52
<PAGE>
 
the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

Section 1007.  Calculation of Original Issue Discount.
               --------------------------------------

     The Corporation shall file with the Trustee promptly at the end of each 
calendar year (i) a written notice specifying the amount of original issue 
discount (including daily rates and accrual periods) accrued on Outstanding 
Securities as of the end of such year and (ii) such other specific information 
relating to such original issue discount as may then be relevant under the 
Internal Revenue Code of 1986, as amended from time to time.

                                  ARTICLE XI.

                           REDEMPTION OF SECURITIES

Section 1101.  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 1102.  Election to Redeem; Notice to Trustee.
               -------------------------------------

     The election of the Corporation to redeem any Securities 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
Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed.  In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

Section 1103.  Selection by Trustee of Securities to Be Redeemed.
               -------------------------------------------------

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series; provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.  If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

                                       53
<PAGE>
 
     The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the 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 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 1104.  Notice of Redemption.
               --------------------

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

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

          (1)  the Redemption Date;

          (2)  the Redemption Price;

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

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

          (5) the place or places where each such Security is to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required;

          (6) that the redemption is for a sinking fund, if such is the case;
     and

          (7) such other matters as the Corporation shall deem desirable or
     appropriate.

                                       54
<PAGE>
 
     Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities.  In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

     Notice of redemption of Securities to be redeemed at the election of the
Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation.  Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

Section 1105.  Securities Payable on Redemption Date.
               -------------------------------------

     Notice of redemption having been given as aforesaid, and the conditions, if
any, set forth in such notice having been satisfied, the Securities or portions
thereof 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 (unless,
in the case of an unconditional notice of redemption, the Corporation shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities or portions thereof, if interest-bearing, shall cease to bear
interest.  Upon surrender of any such Security for redemption in accordance with
said notice, such Security or portion thereof shall be paid by the Corporation
at the Redemption Price, together with accrued interest, if any, to the
Redemption Date; provided, however, that no such surrender shall be a condition
to such payment if so specified as contemplated by Section 301 with respect to
such Security, and provided further that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will 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.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

<PAGE>
 
Section 1106.  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 Corporation or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Corporation and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing), and the Corporation shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series and of like
tenor, 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.

                                 ARTICLE XII.

                                 SINKING FUNDS

Section 1201.  Applicability of Article.
               ------------------------

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment," and
any payment in excess of such minimum amount provided for by the terms of such

payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited.  The Securities to be so credited shall be

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if

any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any

                                 ARTICLE XIII.

                      DEFEASANCE AND COVENANT DEFEASANCE

Section 1301.  Applicability of Article.
               ------------------------

     Unless, pursuant to Section 301, provision is made that either or both of
(A) defeasance of any Securities or any series of Securities under Section 1302
and (B) covenant defeasance of any Securities or any series of Securities under
Section 1303 shall not apply to such Securities of a series, then the provisions
of either or both of Sections 1302 and Section 1303, as the case may be,
together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

Section 1302.  Defeasance and Discharge.
               ------------------------

     The Corporation may cause itself to be discharged from its obligations with
respect to any Securities or any series of Securities on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance").  For this purpose, such Defeasance means that the Corporation
shall be deemed to have paid and discharged the entire indebtedness represented
by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder:  (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003 and with respect to the Trustee under Section 607, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article.  Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the
Corporation of its rights under Section 1303 with

                                       57
<PAGE>
 
respect to such Securities. Following a Defeasance, payment of such Securities
may not be accelerated because of an Event of Default.

Section 1303.  Covenant Defeasance.
               -------------------

     The Corporation may cause itself to be released from its obligations under
any covenants provided pursuant to Section 301(19), 901(2), 901(6) or 901(7)
with respect to any Securities or any series of Securities for the benefit of
the Holders of such Securities and the occurrence of any event specified in
Sections 501(4) (with respect to any such covenants provided pursuant to Section
301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed not to be or result
in an Event of Default with respect to such Securities as provided in this
Section, in each case on and after the date the conditions set forth in Section
1304 are satisfied (hereinafter called "Covenant Defeasance").  For this
purpose, such Covenant Defeasance means that, with respect to such Securities,
the Corporation may omit to comply with and shall have no liability in respect
of any term, condition or limitation set forth in any such specified Section (to
the extent so specified in the case of Section 501(4)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

Section 1304.  Conditions to Defeasance or Covenant Defeasance.
               -----------------------------------------------

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be:

          (1) The Corporation shall irrevocably have deposited or caused to be
     deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (A)
     money in an amount, or (B) Government Obligations which through the
     scheduled payment of principal and interest in respect thereof in
     accordance with their terms will provide, not later than the due date of
     any payment, money in an amount, or (C) a combination thereof, sufficient,
     in the case of (B) or (C), in the opinion of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge, and which shall be
     applied by the Trustee to pay and discharge, the principal of and any
     premium and interest on such Securities on the respective Stated Maturities
     or on any Redemption Date established pursuant to Clause (3) below, in
     accordance with the terms of this Indenture and such Securities.  As used
     herein, "Government Obligation" means (x) any security which is (i) a
     direct obligation of the United States of America or the government which
     issued the foreign currency in which such Securities are payable, for the
     payment of which its full faith and credit is pledged or (ii) an obligation
     of a Person controlled or supervised by and acting as an agency or
     instrumentality of the United States of America or such government which
     issued the foreign currency in which such Securities are payable, the
     payment of which is unconditionally guaranteed as a full faith and credit
     obligation by the United States of America or such other government, which,
     in either

                                       58
<PAGE>
 
     case (i) or (ii), is not callable or redeemable at the option of the issuer
     thereof, and (y) any depositary receipt issued by a bank (as defined in
     Section 3(a)(2) of the Securities Act) as custodian with respect to any
     Government Obligation which is specified in clause (x) above and held by
     such bank for the account of the holder of such depositary receipt, or with
     respect to any specific payment of principal of or interest on any
     Government Obligation which is so specified and held, provided that (except
     as required by law) such custodian is not authorized to make any deduction
     from the amount payable to the holder of such depositary receipt from any
     amount received by the custodian in respect of the Government Obligation or
     the specific payment of principal or interest evidenced by such depositary
     receipt.

          (2) No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities or any other
     Securities shall have occurred and be continuing at the time of such
     deposit or, with regard to any such event specified in Sections 501(5) and
     (6), at any time on or prior to the 90th day after the date of such deposit
     (it being understood that this condition shall not be deemed satisfied
     until after such 90th day).

          (3) If the Securities are to be redeemed prior to Stated Maturity
     (other than from mandatory sinking fund payments or analogous payments),
     notice of such redemption shall have been duly given pursuant to this
     Indenture or provision therefor satisfactory to the Trustee shall have been
     made.

          (4) The Corporation shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent with respect to such Defeasance or Covenant Defeasance have been
     complied with.

Section 1305.  Deposited Money and Government Obligations to Be Held in Trust;
               ---------------------------------------------------------------
               Miscellaneous Provisions.
               ------------------------

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 1304 in respect of any Securities shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

     The Corporation shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1304 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Corporation from time to time upon Company Request any
money or Government

                                       59
<PAGE>
 
Obligations held by it as provided in Section 1304 with respect to any
Securities which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to such Securities.

                                 ARTICLE XIV.

                   IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                            OFFICERS AND DIRECTORS

Section 1401.  Indenture and Securities Solely Corporate Obligations.
               -----------------------------------------------------

     No recourse for the payment of the principal of or any premium or interest
on any Security, or for any claim based thereon or otherwise in respect thereof,
and no recourse under or upon any obligation, covenant or agreement of the
Corporation in this Indenture or in any supplemental indenture, or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Corporation or of any successor
corporation, either directly or through the Corporation or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities.

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

Section 102.  Compliance Certificates and Opinions.
              ------------------------------------

     Upon any application or request by the Corporation to the Trustee to take
any action under any provision of this Indenture, the Corporation shall furnish
to the Trustee such certificates and opinions as may be required under the Trust
Indenture Act.  Each such certificate or opinion shall be given in the form of

Opinion of Counsel, if to be given by counsel, and shall comply with the
requirements of the Trust Indenture Act and any other requirements set forth in

covenant provided for in this Indenture shall include

     opinion has read such covenant or condition and the definitions herein
     relating thereto;

     an informed opinion as to whether or not such covenant or condition has

                                       7
<PAGE>
 
Section 103.  Form of Documents Delivered to Trustee.
              --------------------------------------

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an officer of the Corporation may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such officer's certificate or opinion is
based are erroneous.  Any such certificate or opinion of counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Corporation stating that the
information with respect to such factual matters is in the possession of the
Corporation, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Whenever, subsequent to the receipt by the Trustee of any Board Resolution,
Officers' Certificate, Opinion of Counsel or other document or instrument, a
clerical, typographical or other inadvertent or unintentional error or omission
shall be discovered therein, a new document or instrument may be substituted
therefor in corrected form with the same force and effect as if originally filed
in the corrected form and, irrespective of the date or dates of the actual
execution and/or delivery thereof, such substitute document or instrument shall
be deemed to have been executed and/or delivered as of the date or dates
required with respect to the document or instrument for which it is substituted.
Anything in this Indenture to the contrary notwithstanding, if any such
corrective document or instrument indicates that action has been taken by or at
the request of the Corporation which could not have been taken had the original
document or instrument not contained such error or omission, the action so taken
shall not be invalidated or otherwise rendered ineffective but shall be and
remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith.  Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation entitled to the benefits of this Indenture equally and ratably with
all other Outstanding Securities, except as aforesaid.

Section 104.  Acts of Holders; Record Dates.
              -----------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied 

                                       8
<PAGE>
 
in and evidenced by one or more instruments of substantially similar tenor
signed by such Holders in person or by 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 Corporation. 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
Corporation, if made in the manner provided in this Section.

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

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

     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 Corporation
in reliance thereon, whether or not notation of such action is made upon such
Security.

     The Corporation may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series; provided that the
Corporation may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke the relevant action, whether or not such
Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date.  Nothing in this paragraph shall
be construed to prevent the Corporation from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the 

                                       9
<PAGE>
 
date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Corporation, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date.  Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be sent to the
Corporation in writing and to each Holder of Securities of the relevant series
in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date.  If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.  Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such 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 principal amount.

Section 105.  Notices, Etc., to Trustee and Corporation.
              -----------------------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders 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 Corporation 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 Corporation 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
     Corporation addressed to it at the address of its principal office
     specified in the first paragraph of this instrument, Attention:  Treasurer,
     or at any other address previously furnished in writing to the Trustee by
     the Corporation.

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 his address as it appears in the Security 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 any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other 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 which 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
which 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.

then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or principal

right of payment to the prior payment in full of all Senior Indebtedness, as
defined in the Indenture, with respect to this series, and this Security is
issued subject to such provisions, and each Holder of this Security, by
acceptance thereof, agrees to and shall be bound by such provisions and
authorizes and directs the Trustee in his, her or its behalf to take such action

the consent of the Holders of a majority in principal amount of the Securities
of all series at the time Outstanding affected thereby (voting as one class).
The Indenture contains provisions permitting the Holders of not less than a
majority in principal amount of the Securities of all series at the time
Outstanding with respect to which a default under the Indenture shall have
occurred and be continuing (voting as one class), on behalf of the Holders of
the Securities of all such series, to waive, with certain exceptions, such past
default with respect to all such series and its consequences.  The Indenture
also permits the Holders of not less than a majority in principal amount of the
Securities of each series at the time 

                                       17
<PAGE>
 
Outstanding, on behalf of the Holders of all Securities of such series, to waive
compliance by the Corporation with certain provisions of the Indenture. 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 therefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than a majority in principal
amount of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee and offered the Trustee reasonable indemnity, and the
Trustee shall not have received from the Holders of a majority in principal
amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity.  The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Corporation, which
is absolute and unconditional, to pay the principal of and any premium 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 Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Corporation in any place where the principal of and any premium
and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Corporation and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Corporation may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

     All Securities of any one series shall be substantially identical except as

Board Resolution referred to above and (subject to Section 303) set forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Corporation and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms or the manner of determining the terms of

     With respect to Securities of a series offered in a Periodic Offering, the
Board Resolution (or action taken pursuant thereto), Officers' Certificate or
supplemental indenture referred to above may provide general terms or parameters
for Securities of such series and provide either that the specific terms of
particular Securities of such series shall be specified in a Company 

                                       22
<PAGE>
 
Order or that such terms shall be determined by the Corporation in accordance
with other procedures specified in a Company Order as contemplated by the third
paragraph of Section 303.

     Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

Section 302.  Denominations.
              -------------

     The Securities of each series shall be issuable only in fully registered
form without coupons and only in such 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 $1,000 and any integral multiple thereof.

Section 303.  Execution, Authentication, Delivery and Dating.
              ----------------------------------------------

     The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, 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 Corporation shall bind the
Corporation, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Corporation may deliver Securities of any series executed by the
Corporation to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities, provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Corporation or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
delivered to the Trustee prior to the time of the first authentication of
Securities of such series.  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,

                                       23
<PAGE>
 
          (1) if the form of such Securities has been established by or pursuant
     to Board Resolution 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, or in the case of
     Securities of a series offered in a Periodic Offering, will be, established
     by or pursuant to Board Resolution as permitted by Section 301, that such
     terms have been, or in the case of Securities of a series offered in a
     Periodic Offering, will be, established in conformity with the provisions
     of this Indenture, subject, in the case of Securities of a series offered
     in a Periodic Offering, to any conditions specified in such Opinion of
     Counsel; and

          (3) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Corporation in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Corporation 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 Trustee in good faith shall
determine that the issue of such Securities pursuant to this Indenture will
affect the Trustee's own rights, duties or immunities under the Securities and
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.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Corporation of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

     Each Security shall be dated the date of its authentication.

     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 of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the
Corporation, and the Corporation shall deliver such Security to the Trustee for
cancellation as provided in Section 309, for all purposes of this 

                                       24
<PAGE>
 
Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

Section 304.  Temporary Securities.
              --------------------

     Pending the preparation of definitive Securities of any series, the
Corporation 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 Corporation 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 the office or agency of the Corporation in a Place of Payment for that
series, without charge to the Holder.  Upon surrender for cancellation of any
one or more temporary Securities of any series, the Corporation shall execute
and the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount.  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 and tenor.

Section 305.  Registration, Registration of Transfer and Exchange.
              ---------------------------------------------------

     The Corporation shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Corporation shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security 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
the office or agency of the Corporation in a Place of Payment for that series,
the Corporation 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 like tenor
and 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 like
tenor and 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 Corporation shall execute, and the 

                                       25
<PAGE>
 
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 Corporation, 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 Corporation or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Corporation 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 1106 not involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are
to be redeemed, the Corporation shall not be required (A) 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 selected for redemption and ending at the close of business on
the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

     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 has notified the
     Corporation that it is unwilling or unable to continue as Depositary for
     such Global Security and a successor Depositary has not been appointed by
     the Corporation within 90 days of receipt by the Corporation of such
     notification, (B) if at any time the Depositary ceases 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 and no successor
     Depositary shall have been appointed by the Corporation within 90 days
     after it became aware of such cessation, or (C) there shall exist such

                                       26
<PAGE>
 
     circumstances, if any, in addition to or in lieu of the foregoing as have
     been specified for this purpose as contemplated by Section 301.
     Notwithstanding the foregoing, the Corporation may at any time in its sole
     discretion determine that Securities issued in the form of a Global
     Security shall no longer be represented in whole or in part by such Global
     Security, and the Trustee, upon receipt of a Company Order therefor, shall
     authenticate and deliver definitive Securities in exchange in whole or in
     part for such Global Security.

          (3) Subject to Clause (2) above, any exchange or transfer of a Global
     Security for other Securities may be made in whole or in part, and all
     Securities issued in exchange for or upon transfer of 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
     1106 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 Corporation
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 Corporation 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
Corporation or the Trustee that such Security has been acquired by a bona fide
purchaser, the Corporation 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 Corporation in its discretion may,
instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Corporation
may require the payment of a sum sufficient to cover any tax, fee, assessment or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee and its agents and
counsel) 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 Corporation, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable 

                                       27
<PAGE>
 
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.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, 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 Corporation, at
its election in each case, as provided in Clause (1) or (2) below:

          (1) The Corporation 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 Corporation
     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 Corporation 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 Corporation of
     such Special Record Date and, in the name and at the expense of the
     Corporation, shall cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be given to each Holder of
     Securities of such series in the manner set forth in Section 106, 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 

                                       28
<PAGE>
 
     business on such Special Record Date and shall no longer be payable
     pursuant to the following Clause (2).

          (2) The Corporation 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, if any, on which such
     Securities may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Corporation 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 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, which were carried by such other Security.

Section 308.  Persons Deemed Owners.
              ---------------------

     Prior to due presentment of a Security for registration of transfer, the
Corporation, the Trustee and any agent of the Corporation or the Trustee may

Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Corporation, the Trustee nor any agent of the Corporation 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 or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Corporation may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Corporation may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Corporation has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture.  All canceled
Securities held by the Trustee shall be disposed of as directed by a Company
Order; provided, however, that the Trustee shall not be required to destroy such
canceled Securities.

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.

Section 311.  CUSIP Numbers.
              -------------

     The Corporation in issuing the Securities 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.

               arrangements satisfactory to the Trustee for the giving of notice
               of redemption by the Trustee in the name, and at the expense, of
               the Corporation,

          and the Corporation, in the case of (i), (ii) or (iii) above, has

series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),

been deleted or modified in an indenture supplemental hereto:

          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 60 days; provided, however, that if the Corporation is
     permitted by the terms of the Securities of such series to defer the
     payment in question, the date on which such payment is due and payable
     shall be the date on which the Corporation is required to make payment
     following such deferral, if such deferral has been elected pursuant to the
     terms of the Securities; or

          (2) default in the payment of the principal of or any premium on any
     Security of that series at its Maturity; or

          (3) default in the making of any sinking fund payment, when and as due

     with or which has expressly been included in this Indenture solely for the
     benefit of series of Securities other than that series), and continuance of
     such default or breach for a period of 90 days after there has been given,
     by registered or certified mail, to the Corporation by the Trustee or to
     the Corporation and the Trustee by the Holders of at least 25% in principal
     amount of the Outstanding Securities of that series a written notice
     specifying such default or breach and requiring it to be remedied and
     stating that such notice is a "Notice of Default" hereunder, unless the
     Trustee, or the Trustee and the Holders of a principal amount of Securities
     of such series not less than the principal amount of Securities the Holders
     of which gave such notice, as the case may be, shall agree in writing to an
     extension of such period prior to its expiration; provided, however, that
     the Trustee, or the Trustee and the Holders of such principal amount of
     Securities of such series, as the case may be, shall be deemed to have
     agreed to an extension of such period if corrective action is initiated by
     the Corporation within such period and is being diligently pursued; or

          (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Corporation in an involuntary
     case or proceeding under any applicable federal or state bankruptcy,
     insolvency, reorganization or other similar law or (B) a decree or order

    for a period of 90 consecutive days; or

          (6) the commencement by the Corporation of a voluntary case or
     proceeding under any applicable federal or state bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Corporation in an
     involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or to the
     commencement of any bankruptcy or insolvency case or proceeding against it,
     or the filing by it of a petition or answer or consent seeking
     reorganization or relief under any applicable federal or state law, or the
     consent by it to the filing of such petition or to the appointment of or
     taking possession by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Corporation or of any
     substantial part of its property, or the making by it of an assignment for
     the benefit of creditors, or the admission by it in writing of its
     inability to pay its debts generally as they become due, or the
     authorization of any such action by the Board of Directors; or

          (7) any other Event of Default provided with respect to Securities of
     that series.

Section 502.  Acceleration of Maturity; Rescission and Annulment.
              --------------------------------------------------

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Event of Default giving rise to such declaration of
acceleration shall, without further act, be deemed to have been waived, and such
declaration and its consequences shall, without further act, be deemed to have
been rescinded and annulled, if

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

              (A) all overdue interest on all Securities of that series,

              (B) the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration 

                                       33
<PAGE>
 
          and any interest thereon at the rate or rates prescribed therefor in
          such Securities,

              (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

              (D) 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 non-payment 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 Corporation covenants that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 60 days, or

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

the Corporation 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 any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses 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 effectual 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 relative to the Corporation (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by 

                                       34
<PAGE>
 
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; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

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.
              ------------------------------

     Any money 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 any premium
or 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 any premium and 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 any premium and interest,
     respectively; and

                                       35
<PAGE>
 
          Third:  To the payment of the balance, if any, to the Corporation or
     any other Person or Persons legally entitled thereto.

Section 507.  Limitation on Suits.
              -------------------


     No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

          (1) such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;

          (2) the Holders of not less than a majority in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (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;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

Section 508.  Unconditional Right of Holders to Receive Principal, Premium 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 any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities 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, 

                                       36
<PAGE>
 
subject to any determination in such proceeding, the Corporation, the Trustee
and the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

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

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the 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 Securities 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.

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, with respect to the Securities of
such series; provided that

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

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

          (3) subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability.

Section 513.  Waiver of Past Defaults.
              -----------------------

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

          (1) in the payment of the principal of or any premium or interest on
     any Security of such series, 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 the series affected.

     Upon any such waiver, such default shall cease to exist and be deemed not
to have occurred, and any Event of Default arising therefrom shall be deemed to
have been cured and not to have occurred, 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 suit 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 Corporation or the Trustee.

Section 515.  Waiver of Stay or Extension Laws.
              --------------------------------

     The Corporation 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 Corporation (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.

Section 601.  Certain Duties and Responsibilities.
              -----------------------------------

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act.  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 a 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(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof.  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.

Section 603.  Certain Rights of Trustee.
              -------------------------

     Subject to the provisions of Section 601:

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

          (2) any request or direction of the Corporation mentioned herein shall
     be sufficiently evidenced by a Company Request or Company Order or as

          (3) whenever in the administration of this Indenture 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 
     Corporation;

                                       39
<PAGE>
 
          (4) the Trustee may consult with counsel of its selection and the
     written advice or Opinion of 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 reliance
     thereon. Such counsel may be counsel to the Corporation or any of its 
     Affiliates, and may include any of its employees;

          (5) 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 Holders shall
     have offered to the Trustee security or indemnity satisfactory to it
     against the costs, expenses and liabilities which might be incurred by it
     in compliance with such request or direction;

          (6) 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, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled, at reasonable times previously notified to the
     Corporation, to examine the relevant books, records and premises of the
     Corporation, personally or by agent or attorney at the sole expense of the
     Corporation and shall incur no liability or additional liability of 
     any kind by reason of such inquiry or investigation; and

          (7) 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.

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
Corporation, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness.  The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities.  Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Corporation of Securities or the proceeds thereof.

Section 605.  May Hold Securities.
              -------------------

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Corporation, 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 Corporation with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

<PAGE>
 
Section 606.  Money Held in Trust.
              -------------------

     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law.  The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Corporation.

Section 607.  Compensation and Reimbursement.
              ------------------------------

     The Corporation agrees

          (1) to pay to the Trustee from time to time such compensation as shall
     be agreed upon from time to time in writing between the Corporation and the
     Trustee 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 expenses, disbursements and advances
     incurred or made by the Trustee in accordance with any provision of this
     Indenture (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, willful
     misconduct or bad faith; and

          (3) to fully 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, willful misconduct or bad faith on its part, arising
     out of or in connection with the acceptance or administration of the trust
     or trusts hereunder, 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 shall have a lien prior to the Securities upon all property and
funds held by it hereunder for any amount owing it or any predecessor Trustee
pursuant to this Section 607, except with respect to funds held in trust for the
benefit of the Holders of particular Securities.

     Without limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section shall survive the termination of this
Indenture.

Section 608.  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.  

                                       41
<PAGE>
 
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 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 condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
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 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.
              -------------------------------------------------

     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 the successor Trustee in accordance with the applicable
requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Corporation.  If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition, at the expense of the
Corporation, any court of competent jurisdiction for the appointment of a
successor Trustee with respect to the Securities of such series.

     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
Corporation. Upon such removal, the Corporation may petition, at the expense of 
the Corporation, any court of competent jurisdiction for the appointment of a 
successor Trustee with respect to the Securities of such series.

     If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Corporation 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 Corporation 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 

                                       42
<PAGE>
 
     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,

then, in any such case, (A) the Corporation by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) 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 himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     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 Corporation, 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) and shall comply with the applicable
requirements of Section 611.  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 Corporation and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 611, become the successor
Trustee with respect to the Securities of such series and to that extent
supersede the successor Trustee appointed by the Corporation.  If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Corporation or the Holders and accepted appointment in the
manner required by Section 611, 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.

     The Corporation 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 name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

Section 611.  Acceptance of Appointment by Successor.
              --------------------------------------

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

                                       43
<PAGE>
 
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 Corporation, 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
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or 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 Corporation or any successor Trustee,
such retiring Trustee shall upon payment of all damages due it, its agents and
counsel 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 Corporation 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.
              -----------------------------------------------------------

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, 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 

                                       44
<PAGE>
 
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.

Section 613.  Preferential Collection of Claims Against Corporation.
              -----------------------------------------------------

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

Section 614.  Appointment of Authenticating Agent.
              -----------------------------------

     The Trustee may appoint an Authenticating Agent or Agents acceptable to the
Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  Wherever reference
is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee's certificate of authentication, such reference shall
be deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Corporation and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by federal or state
authority.  If such Authenticating Agent 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, the combined capital
and surplus of such Authenticating Agent 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 an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent 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 Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided that such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Corporation.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the 

                                       45
<PAGE>
 
Corporation. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Corporation and shall give notice of such appointment in the manner provided in
Section 106 to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

     The Corporation agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

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

     Any application by the Trustee for written instructions from the
Corporation may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable to the Corporation for any action
taken by, or omission of, the Trustee in accordance with a proposal included in
such application on or after the date specified in such application (which date
shall not be less than three Business Days after the date any officer of the
corporation actually receives such application, unless any such officer shall

rights and privileges of the Trustee, shall be as provided by the Trust
Indenture Act.

     Every Holder of Securities, by receiving and holding the same, agrees with
the Corporation and the Trustee that neither the Corporation nor the Trustee nor

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

     The Trustee shall transmit to Holders such reports concerning the Trustee

constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Corporation's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     series) or to surrender any right or power herein conferred upon the
     Corporation; or

          (3) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events
     of Default are to be for the benefit of less than all series of Securities,
     stating that such additional Events of Default are expressly being included
     solely for the benefit of such series); or

          (4) to add to or change any of the provisions of this Indenture to

     indenture and entitled to the benefit of such provision nor (ii) modify the

     of Securities of any series in any material respect.

Section 902.  Supplemental Indentures With Consent of Holders.
              -----------------------------------------------

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of all series affected by such supplemental
indenture (voting as one class), by Act of said Holders delivered to the
Corporation and the Trustee, the Corporation, when authorized by a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture, or modifying in any manner the rights of the Holders of
Securities under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security or any other Security which would be due
     and payable upon a declaration of acceleration of the Maturity thereof
     pursuant to Section 502 or change the coin or currency in which any
     Security or any premium or interest thereon is payable, or impair the right
     to institute suit for the enforcement of any such payment on or after the
     Stated Maturity thereof (or, in the case of redemption, on or after the
     Redemption Date), or

          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or

          (3) modify any of the provisions of this Section, Section 513 or
     Section 1006, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1006, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611 and 901(8).  A supplemental indenture which changes or eliminates any
     covenant or other provision of this Indenture which has expressly been
     included solely for the benefit of one or more particular series of
     Securities, or which modifies the rights of the Holders of Securities of
     such series with respect to such covenant or other provision, shall be
     deemed not to affect the rights under this Indenture of the Holders of
     Securities of any other series.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is

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

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental

by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Corporation shall so
determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Corporation, to any such supplemental indenture
may be prepared and executed by the Corporation and authenticated and delivered
by the Trustee in exchange for Outstanding Securities of such series.

Section 907.  Subordination Unimpaired.
              ------------------------

     This Indenture may not be amended to alter the subordination of any of the

Section 1002.  Maintenance of Office or Agency.
               -------------------------------

     The Corporation will maintain in each Place of Payment for any series of
Securities an office or agency 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 and where notices and demands to or
upon the Corporation in respect of the Securities of that series and this
Indenture may be served.  The Corporation 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 Corporation 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 Corporation hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

     The Corporation may also from time to time designate one or more other
offices or agencies 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 Corporation of its obligation to maintain an
office or agency in each Place of Payment for Securities of any series for such
purposes.  The Corporation 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 Securities Payments to Be Held in Trust.
               -------------------------------------------------

     If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium 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 and any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium 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 Corporation will promptly notify the Trustee of its action or
failure so to act.

     The Corporation will cause each Paying Agent for any series of Securities
other than the Trustee 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, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Corporation (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 for payment in
respect of the Securities of that series.

                                       52
<PAGE>
 
     The Corporation 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 hereunder by the Corporation 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
Corporation 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 Corporation, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Corporation on Company Request, or (if then held by the Corporation)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Corporation for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Corporation as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Corporation cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Corporation.

Section 1004.  Corporate Existence.
               -------------------

     Subject to Article Eight, the Corporation will do or cause to be done all

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

     The Corporation will deliver to the Trustee, on or before October 15 of
each calendar year or on or before such other day in each calendar year as the
Corporation and the Trustee may from time to time agree upon, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Corporation is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Corporation
shall be in default, specifying all such defaults and the nature and status
thereof of which they may have knowledge.

Section 1006.  Waiver of Certain Covenants.
               ---------------------------

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series, the Corporation may, with respect to the Securities of any
series, omit in any particular instance to comply with any term, provision or
condition set forth in any covenant provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such series if 

                                       53
<PAGE>
 
before the time for such compliance the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series shall, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.



                                  ARTICLE XI.

                            REDEMPTION OF SECURITIES

Section 1101.  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 1102.  Election to Redeem; Notice to Trustee.
               -------------------------------------

     The election of the Corporation to redeem any Securities 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
Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed.  In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

Section 1103.  Selection by Trustee of Securities to Be Redeemed.
               -------------------------------------------------

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series; provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.  If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the 

                                       54
<PAGE>
 
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

     The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the 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 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 1104.  Notice of Redemption.
               --------------------

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

          (1)  the Redemption Date;

          (2)  the Redemption Price;

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

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

          (5) the place or places where each such Security is to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required;

                                       55
<PAGE>
 
          (6) that the redemption is for a sinking fund, if such is the case;
     and

          (7) such other matters as the Corporation shall deem desirable or
     appropriate.

     Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities.  In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

     Notice of redemption of Securities to be redeemed at the election of the
Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation.  Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

Section 1105.  Securities Payable on Redemption Date.
               -------------------------------------

     Notice of redemption having been given as aforesaid, and the conditions, if
any, set forth in such notice having been satisfied, the Securities or portions
thereof 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 (unless,
in the case of an unconditional notice of redemption, the Corporation shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities or portions thereof, if interest-bearing, shall cease to bear
interest.  Upon surrender of any such Security for redemption in accordance with
said notice, such Security or portion thereof shall be paid by the Corporation
at the Redemption Price, together with accrued interest, if any, to the
Redemption Date; provided, however, that no such surrender shall be a condition
to such payment if so specified as contemplated by Section 301 with respect to
such Security, and provided further that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will 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.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

Section 1106.  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 Corporation or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Corporation and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing), and the Corporation shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series and of like
tenor, 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.

Section 1201.  Applicability of Article.
               ------------------------

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment," and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment."  If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202.  Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

Section 1202.  Satisfaction of Sinking Fund Payments with Securities.
               -----------------------------------------------------

     The Corporation (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited.  The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

Section 1203.  Redemption of Securities for Sinking Fund.
               -----------------------------------------

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered.  Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104.  Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1105 and 1106.


                                 ARTICLE XIII.

                      DEFEASANCE AND COVENANT DEFEASANCE

Section 1301.  Applicability of Article.
               ------------------------

     Unless, pursuant to Section 301, provision is made that either or both of
(A) defeasance of any Securities or any series of Securities under Section 1302
and (B) covenant defeasance of any Securities or any series of Securities under
Section 1303 shall not apply to such Securities of a series, then the provisions
of either or both of Sections 1302 and Section 1303, as the case may be,
together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

Section 1302.  Defeasance and Discharge.
               ------------------------

     The Corporation may cause itself to be discharged from its obligations with
respect to any Securities or any series of Securities on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance").  For this purpose, such Defeasance means that the Corporation
shall be deemed to have paid and discharged the entire indebtedness represented
by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Corporation, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder:  (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal of
and any premium and interest on such Securities when payments are due, (2) the
Corporation's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003 and with respect to the Trustee under Section 607, (3)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(4) this Article.  Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities by the Corporation is
permitted under this Section 1302 notwithstanding the prior exercise by the
Corporation of its rights under Section 1303 with 

                                       58
<PAGE>
 
respect to such Securities. Following a Defeasance, payment of such Securities
may not be accelerated because of an Event of Default.

Section 1303.  Covenant Defeasance.
               -------------------

     The Corporation may cause itself to be released from its obligations under
any covenants provided pursuant to Section 301(19), 901(2), 901(6) or 901(7)
with respect to any Securities or any series of Securities for the benefit of
the Holders of such Securities and the occurrence of any event specified in
Sections 501(4) (with respect to any such covenants provided pursuant to Section
301(19), 901(2), 901(6) or 901(7)) or 501(7) shall be deemed not to be or result
in an Event of Default with respect to such Securities as provided in this
Section, in each case on and after the date the conditions set forth in Section
1304 are satisfied (hereinafter called "Covenant Defeasance").  For this
purpose, such Covenant Defeasance means that, with respect to such Securities,
the Corporation may omit to comply with and shall have no liability in respect
of any term, condition or limitation set forth in any such specified Section (to
the extent so specified in the case of Section 501(4)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

Section 1304.  Conditions to Defeasance or Covenant Defeasance.
               -----------------------------------------------

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be:

          (1) The Corporation shall irrevocably have deposited or caused to be
     deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (A)
     money in an amount, or (B) Government Obligations which through the
     scheduled payment of principal and interest in respect thereof in
     accordance with their terms will provide, not later than the due date of
     any payment, money in an amount, or (C) a combination thereof, sufficient,
     in the case of (B) or (C), in the opinion of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge, and which shall be
     applied by the Trustee to pay and discharge, the principal of and any
     premium and interest on such Securities on the respective Stated Maturities
     or on any Redemption Date established pursuant to Clause (3) below, in
     accordance with the terms of this Indenture and such Securities.  As used
     herein, "Government Obligation" means (x) any security which is (i) a
     direct obligation of the United States of America or the government which
     issued the foreign currency in which such Securities are payable, for the
     payment of which its full faith and credit is pledged or (ii) an obligation
     of a Person controlled or supervised by and acting as an agency or
     instrumentality of the United States of America or such government which
     issued the foreign currency in which such Securities are payable, the
     payment of which is unconditionally guaranteed as a full faith and credit
     obligation by the United States of America or such other government, which,
     in either 

                                       59
<PAGE>
 
     case (i) or (ii), is not callable or redeemable at the option of the issuer
     thereof, and (y) any depositary receipt issued by a bank (as defined in
     Section 3(a)(2) of the Securities Act) as custodian with respect to any
     Government Obligation which is specified in clause (x) above and held by
     such bank for the account of the holder of such depositary receipt, or with
     respect to any specific payment of principal of or interest on any
     Government Obligation which is so specified and held, provided that (except
     as required by law) such custodian is not authorized to make any deduction
     from the amount payable to the holder of such depositary receipt from any
     amount received by the custodian in respect of the Government Obligation or
     the specific payment of principal or interest evidenced by such depositary
     receipt.

          (2) No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities or any other
     Securities shall have occurred and be continuing at the time of such
     deposit or, with regard to any such event specified in Sections 501(5) and
     (6), at any time on or prior to the 90th day after the date of such deposit
     (it being understood that this condition shall not be deemed satisfied
     until after such 90th day).

          (3) If the Securities are to be redeemed prior to Stated Maturity
     (other than from mandatory sinking fund payments or analogous payments),
     notice of such redemption shall have been duly given pursuant to this
     Indenture or provision therefor satisfactory to the Trustee shall have been
     made.

          (4) The Corporation shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent with respect to such Defeasance or Covenant Defeasance have been
     complied with.

Section 1305.  Deposited Money and Government Obligations to Be Held in Trust;
               ---------------------------------------------------------------
               Miscellaneous Provisions.
               ------------------------

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 1304 in respect of any Securities shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Securities and this Indenture, to the payment, either directly or through any
such Paying Agent (including the Corporation acting as its own Paying Agent) as
the Trustee may determine, to the Holders of such Securities, of all sums due
and to become due thereon in respect of principal and any premium and interest,
but money so held in trust need not be segregated from other funds except to the
extent required by law.

     The Corporation shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1304 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Corporation from time to time upon Company Request any
money or Government 

                                       60
<PAGE>
 
Obligations held by it as provided in Section 1304 with respect to any
Securities which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect the Defeasance or Covenant Defeasance, as the case may be,
with respect to such Securities.


                                 ARTICLE XIV.

                                 SUBORDINATION

Section 1401.  Securities Subordinated to Senior Indebtedness.
               ----------------------------------------------

     Except as otherwise specified as contemplated by Section 301 for any series
of Securities, the Corporation covenants and agrees, and each Holder of a
Security, by his acceptance thereof, likewise covenants and agrees, that the
indebtedness represented by the Securities of any series and the payment of the
principal of and any premium or interest on each and all of the Securities of
each series is subordinate, to the extent and in the manner hereinafter set
forth, in right of payment to the prior payment in full of all Senior
Indebtedness.  Senior Indebtedness shall continue to be Senior Indebtedness and
entitled to the benefits of these subordination provisions irrespective of any
amendment, modification or waiver of any term of the Senior Indebtedness or
extension or renewal of the Senior Indebtedness.

     In the event (a) of any payment by, or distribution of assets of, the
Corporation of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution, winding-up, liquidation or reorganization of
the Corporation, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, or (b) subject to the provisions of Section
1402 that (i) a default shall have occurred and be continuing with respect to
the payment of principal, interest or any other monetary amounts due and payable
on any Senior Indebtedness and such default shall have continued beyond the
period of grace, if any, specified in the instrument evidencing such Senior
Indebtedness (and the Trustee shall have received written notice thereof from
the Corporation or one or more holders of Senior Indebtedness or their
representative or representatives or the trustee or trustees under any indenture
pursuant to which any such Senior Indebtedness may have been issued), or (ii)
the maturity of any Senior Indebtedness shall have been accelerated because of a
default in respect of such Senior Indebtedness (and the Trustee shall have
received written notice thereof from the Corporation or one or more holders of
Senior Indebtedness or their representative or representatives or the trustee or
trustees under any indenture pursuant to which any such Senior Indebtedness may
have been issued), then:

          (i)  the holders of all Senior Indebtedness shall first be entitled to
     receive, in the case of (a) above, payment of all amounts due or to become
     due upon all Senior Indebtedness and, in the case of subclauses (i) and
     (ii) of clause (b) above, payment of all amounts due thereon, or provision
     shall be made for such payment in money or money's worth, before the
     Holders of any of the Securities are entitled to receive any payment on
     account of the principal of or any premium or interest on the indebtedness
     evidenced by 

                                       61
<PAGE>
 
     the Securities, including, without limitation, any payments made pursuant
     to Article Eleven or Article Twelve;

          (ii)  any payment by, or distribution of assets of, the Corporation of
     any kind or character, whether in cash, property or securities, to which
     the Holders of any of the Securities would be entitled except for the
     provisions of this Article, including any such payment or distribution
     which may be payable or deliverable by reason of the payment of any other
     indebtedness of the Corporation being subordinated to the payment of such
     Securities, shall be paid or delivered by the Person making such payment or
     distribution, whether a trustee in bankruptcy, a receiver or liquidating
     trustee or otherwise, directly to the holders of such 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 such Senior Indebtedness
     held or represented by each, to the extent necessary to make payment in
     full of all Senior Indebtedness remaining unpaid after giving effect to any
     concurrent payment or distribution (or provision therefor) to the holders
     of such Senior Indebtedness, before any payment or distribution is made to
     the Holders of the indebtedness evidenced by such Securities; and

          (iii)  in the event that, notwithstanding the foregoing, any payment
     by, or distribution of assets of, the Corporation 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 Corporation being subordinated to the
     payment of such Securities, in respect of principal of or any premium or
     interest on any of the Securities or in connection with the repurchase by
     the Corporation of any of the Securities, shall be received by the Trustee
     or the Holders of any of the Securities when such payment or distribution
     is prohibited pursuant to this Section, such payment or distribution shall
     be paid over to the holders of such Senior Indebtedness or their
     representative or representatives or to the trustee or trustees under any
     indenture pursuant to which any instruments evidencing any such Senior
     Indebtedness may have been issued, ratably as aforesaid, for application to
     the payment of all Senior Indebtedness remaining unpaid until all such
     Senior Indebtedness shall have been paid in full, after giving effect to
     any concurrent payment or distribution (or provision therefor) to the
     holders of such Senior Indebtedness.

     Notwithstanding the foregoing, at any time after the 90th day following the
date of deposit of money or Government Obligations pursuant to Section 1304
(provided all other conditions set out in such Section shall have been
satisfied) the funds so deposited and any interest thereon will not be subject
to any rights of holders of Senior Indebtedness including, without limitation,
those arising under this Article.

     For purposes of this Article Fourteen, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Corporation as
reorganized or readjusted, or securities of the Corporation or any other Person
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article with respect to

                                       62
<PAGE>
 
the Securities to the payment of all Senior Indebtedness which may at the time
be outstanding; provided that (i) the indebtedness or guarantee of indebtedness,
as the case may be, that constitutes Senior Indebtedness is assumed by the
Person, if any, resulting from any such reorganization or readjustment, and (ii)
the rights of the holders of the Senior Indebtedness are not, without the
consent of each such holder adversely affected thereby, altered by such
reorganization or readjustment.  The consolidation of the Corporation with, or
the merger of the Corporation into, another Person or the liquidation or
dissolution of the Corporation following the conveyance or transfer of its
property as an entirety, or substantially as an entirety, to another Person upon
the terms and conditions provided for in Article Eight hereof shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section if such other Person shall, as part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
Eight hereof.

Section 1402.  Disputes with Holders of Certain Senior Indebtedness.
               ----------------------------------------------------

     Any failure by the Corporation to make any payment on or perform any other
obligation under Senior Indebtedness, other than any indebtedness incurred by
the Corporation or assumed or guaranteed, directly or indirectly, by the
Corporation for money borrowed (or any deferral, renewal, extension or refunding
thereof) or any indebtedness or obligation as to which the provisions of this
Section shall have been waived by the Corporation in the instrument or
instruments by which the Corporation incurred, assumed, guaranteed or otherwise
created such indebtedness or obligation, shall not be deemed a default or event
of default under Section 1401(b) if (i) the Corporation shall be disputing its
obligation to make such payment or perform such obligation and (ii) either (A)
no final judgment relating to such dispute shall have been issued against the
Corporation which is in full force and effect and is not subject to further
review, including a judgment that has become final by reason of the expiration
of the time within which a party may seek further appeal or review, and (B) in
the event of a judgment that is subject to further review or appeal has been
issued, the Corporation shall in good faith be prosecuting an appeal or other
proceeding for review and a stay of execution shall have been obtained pending
such appeal or review.

Section 1403.  Subrogation.
               -----------

     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
obligations of the Corporation which by their express terms are subordinated to
Senior Indebtedness of the Corporation to the same extent as the Securities are
subordinated and which are entitled to like rights of subrogation) to the rights
of the holders of Senior Indebtedness to receive payments or distributions of
cash, property or securities of the Corporation applicable to the Senior
Indebtedness until all amounts owing on the Securities shall be paid in full,
and as between the Corporation, its creditors other than holders of such Senior
Indebtedness and the Holders, no such payment or distribution made to the
holders of Senior Indebtedness by virtue of this Article that otherwise would
have been made to the Holders shall be deemed to be a payment by the Corporation
on account of such Senior Indebtedness, it being understood that the provisions
of 

                                       63
<PAGE>
 
this Article are and are intended solely for the purpose of defining the
relative rights of the Holders, on the one hand, and the holders of Senior
Indebtedness, on the other hand.

Section 1404.  Obligation of Corporation Unconditional.
               ---------------------------------------

     Nothing contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall impair, as among the Corporation, its
creditors other than the holders of Senior Indebtedness and the Holders, the
obligation of the Corporation, which is absolute and unconditional, to pay to
the Holders the principal of and any premium or interest on the Securities as
and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the Holders and
creditors of the Corporation other than the holders of Senior Indebtedness, nor
shall anything herein or therein prevent the Trustee or any Holder from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness in respect of cash, property or securities of the
Corporation received upon the exercise of any such remedy.

     Upon payment or distribution of assets of the Corporation referred to in
this Article, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any such
dissolution, winding-up, liquidation or reorganization proceeding affecting the
affairs of the Corporation is pending or upon a certificate of the trustee in
bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee
or agent or other person making any payment or distribution, delivered to the
Trustee or to the Holders, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Corporation, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

     The Trustee shall be entitled to rely on the delivery to it of a written
notice by a Person representing himself to be a holder of Senior Indebtedness
(or a trustee or representative on behalf of such holder) to establish that such
notice has been given by a holder of Senior Indebtedness or a trustee or
representative on behalf of any such holder or holders.  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 payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

Section 1405.  Payments on Securities Permitted.
               --------------------------------

     Nothing contained in this Article or elsewhere in this Indenture or in the
Securities shall affect the obligations of the Corporation to make, or prevent
the Corporation from making, 

                                       64
<PAGE>
 
payment of the principal of or any premium or interest on the Securities in
accordance with the provisions hereof and thereof, except as otherwise provided
in this Article.

Section 1406.  Effectuation of Subordination by Trustee.
               ----------------------------------------

     Each Holder of Securities, by his acceptance thereof, authorizes and
directs the Trustee in his, her or its behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Article and appoints the Trustee his, her or its attorney-in-fact, as the case
may be, for any and all such purposes.

Section 1407.  Knowledge of Trustee.
               --------------------

     The Corporation shall give prompt written notice to the Trustee of any fact
known to the Corporation which would prohibit the making of any payment of
moneys to or by the Trustee in respect of the Securities pursuant to the
provisions of this Article.  Notwithstanding the provisions of this Article or
any other provisions of this Indenture, the Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment of moneys to or by the Trustee, or the taking of any other action by the
Trustee, unless and until the Trustee shall have received written notice thereof
mailed or delivered to the Trustee at its Corporate Trust Office from the
Corporation, any Holder, any paying agent or the holder or representative of any
Senior Indebtedness; provided that if at least two Business Days prior to the
date upon which by the terms hereof any such moneys may become payable for any
purpose (including, without limitation, the payment of the principal or any
premium or interest on any Security) the Trustee shall not have received with
respect to such moneys the notice provided for in this Section, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such moneys and to apply the same to the purpose
for which they were received and shall not be affected by any notice to the
contrary that may be received by it within two Business Days prior to or on or
after such date.

Section 1408.  Trustee May Hold Senior Indebtedness.
               ------------------------------------

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Indebtedness at the time
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.

Section 1409.  Rights of Holders of Senior Indebtedness Not Impaired.
               -----------------------------------------------------

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

     With respect to the holders of Senior Indebtedness, (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions
of this Indenture; (ii) the Trustee 

                                       65
<PAGE>
 
shall not be liable except for the performance of such duties and obligations as
are specifically set forth in this Indenture; (iii) no implied covenants or
obligations shall be read into this Indenture against the Trustee; and (iv) the
Trustee shall not be deemed to be a fiduciary as to such holders.

Section 1410.  Trust Moneys Not Subordinated.
               -----------------------------

     Notwithstanding anything contained herein to the contrary, payments from
money or Government Obligations held in trust under Article Four or Article
Thirteen by the Trustee for the payment of principal of and any premium or
interest on the Securities of any series shall not be subordinated to the prior
payment of any Senior Indebtedness of the Corporation or subject to the
restrictions set forth in this Article and none of the Holders shall be
obligated to pay over any such amount to the Corporation or any holder of Senior
Indebtedness or any other creditor of the Corporation.

Section 1411.  Article Applicable to Paying Agents.
               -----------------------------------

     In case at any time any paying agent other than the Trustee shall have been
appointed by the Corporation and be then acting hereunder, the term "Trustee" as
used in this Article shall in such case (unless the context shall otherwise
require) 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 in addition to or in place of the Trustee; provided, however,
that Sections 1407 and 1408 shall not apply to the Corporation if it acts as its
own paying agent.

Section 1412.  Trustee; Compensation Not Prejudiced.
               ------------------------------------

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

Section 1501.  Indenture and Securities Solely Corporate Obligations.
               -----------------------------------------------------

     No recourse for the payment of the principal of or any premium or interest
on any Security, or for any claim based thereon or otherwise in respect thereof,
and no recourse under or upon any obligation, covenant or agreement of the
Corporation in this Indenture or in any supplemental indenture, or in any
Security, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator, stockholder, officer or director, as
such, past, present or future, of the Corporation or of any successor
corporation, either directly or through the Corporation or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities.

Trustee to take any action under any provision of this Indenture, the
Corporation and the Guarantor shall each furnish to the Trustee such

     In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any certificate or opinion of an officer of the Corporation or the
Guarantor may be based, insofar as it relates to legal matters, upon a
certificate or opinion of, or representations by, counsel, unless such officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which such
officer's certificate or opinion is based are erroneous.  Any such certificate
or opinion of counsel may be based, insofar as it relates to factual matters,
upon a certificate or opinion of, or representations by, an officer or officers
of the Corporation or the Guarantor stating that the information with respect to
such factual matters is in the possession of the Corporation or the Guarantor,
as the case requires, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Whenever, subsequent to the receipt by the Trustee of any Board Resolution,
Officers' Certificate, Opinion of Counsel or other document or instrument, a
clerical, typographical or other inadvertent or unintentional error or omission
shall be discovered therein, a new document or instrument may be substituted
therefor in corrected form with the same force and effect as if originally filed
in the corrected form and, irrespective of the date or dates of the actual
execution and/or delivery thereof, such substitute document or instrument shall
be deemed to have been executed and/or delivered as of the date or dates
required with respect to the document or instrument for which it is substituted.
Anything in this Indenture to the contrary notwithstanding, if any action has
been taken by or at the request of the Corporation or the Guarantor in reliance
on an error or omission in the original document which should have been
corrected, the action so taken

                                       8
<PAGE>
 
shall not be invalidated or otherwise rendered ineffective but shall be and
remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith. Without limiting the generality of
the foregoing, any Securities issued under the authority of such defective
document or instrument shall nevertheless be the valid obligations of the
Corporation or the Guarantor, as the case may be, entitled to the benefits of
this Indenture equally and ratably with all other Outstanding Securities, except
as aforesaid.

Section 104.  Acts of Holders; Record Dates.
              -----------------------------

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by 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 Corporation
and the Guarantor. 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, the Corporation and the Guarantor, if made in the manner
provided in this Section.

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

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

     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, the Corporation or
the Guarantor in reliance thereon, whether or not notation of such action is
made upon such Security.

     Each of the Corporation and the Guarantor  may set any day as a record date
for the purpose of determining the Holders of Outstanding Securities of any
series entitled to give, make or take any request, demand, authorization,
direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given, made or taken by Holders of Securities of such series;
provided that the Corporation and the Guarantor may not set a record date for,
and the provisions of this paragraph shall not apply with respect to, the giving
or making of any 

                                       9
<PAGE>
 
notice, declaration, request or direction referred to in the next paragraph. If
any record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take or revoke the relevant action, whether or not such
Holders remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Corporation or the Guarantor from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Corporation or the
Guarantor, at their own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction or to revoke
the same, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date.  Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Corporation's or Guarantor's expense, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be sent to
the Corporation and the Guarantor in writing and to each Holder of Securities of
the relevant series in the manner set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date.  If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date 

                                       10
<PAGE>
 
shall be deemed to have initially designated the 180th day after such record
date as the Expiration Date with respect thereto, subject to its right to change
the Expiration Date as provided in this paragraph. Notwithstanding the
foregoing, no Expiration Date shall be later than the 180th day after the
applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such 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 principal amount.

     or at any other address previously furnished in writing to the Trustee by
     the Corporation.

          (3) the Guarantor 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 Guarantor
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument, Attention:  Treasurer, or at any other
     address previously furnished in writing to the Trustee by the Guarantor.

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 his address as it appears in the Security 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 any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other 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 by
such Holder or the Corporation with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

                                       11

     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 which 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
which 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.

Guarantor shall bind its successors and assigns, whether so expressed or not.

Section 110.  Separability Clause.
              -------------------

     In case any provision in this Indenture or in the Securities or the
Guarantees 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.

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

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision of any Security which specifically states that such
provision shall apply in lieu of this Section)) payment of interest or

     exceptions to those set forth in Section 1401; and

          (21)  any other terms of the series.

     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 forth, or
determined in the manner provided, in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Corporation and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms or the manner of determining the terms of
the series.

     With respect to Securities of a series offered in a Periodic Offering, the
Board Resolution (or action taken pursuant thereto), Officers' Certificate or
supplemental indenture referred to above may provide general terms or parameters
for Securities of such series and provide either 

                                       22
<PAGE>
 
that the specific terms of particular Securities of such series shall be
specified in a Company Order or that such terms shall be determined by the
Corporation in accordance with other procedures specified in a Company Order as
contemplated by the third paragraph of Section 303.

     Notwithstanding Section 301(2) herein and unless otherwise expressly
provided with respect to a series of Securities, the aggregate principal amount
of a series of Securities may be increased and additional Securities of such
series may be issued up to the maximum aggregate principal amount authorized
with respect to such series as increased.

Section 302.  Denominations.
              -------------

     The Securities of each series shall be issuable only in fully registered
form without coupons and only in such 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 $1,000 and any integral multiple thereof.

Section 303.  Execution, Authentication, Delivery and Dating.
              ----------------------------------------------

     The Securities shall be executed on behalf of the Corporation by its
Chairman of the Board, its Vice Chairman of the Board, its Chief Executive
Officer, 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 Corporation shall bind the
Corporation, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

     Unless otherwise provided as contemplated by Section 301, with respect to
any series of Securities, Guarantees to be endorsed on any Securities shall be
executed and delivered in accordance with the provisions of Section 1402.

     At any time and from time to time after the execution and delivery of this
Indenture, the Corporation may deliver Securities of any series executed by the
Corporation, with the Guarantees endorsed thereon, to the Trustee for
authentication, together with a Company Order and a Guarantor Order for the
authentication and delivery of such Securities and the Guarantees endorsed
thereon, and the Trustee in accordance with the Company Order and the Guarantor
Order shall authenticate and deliver such Securities and the Guarantees endorsed
thereon, provided, however, that in the case of Securities offered in a Periodic
Offering, the Trustee shall authenticate and deliver such Securities, and the
Guarantees endorsed thereon, from time to time in accordance with such other
procedures (including, without limitation, the receipt by the Trustee of oral or
electronic instructions from the Corporation or its duly authorized agents,
promptly confirmed in writing) acceptable to the Trustee as may be specified by
or pursuant to a Company Order and a Guarantor Order delivered to the Trustee
prior to the time of the first 

                                       23
<PAGE>
 
authentication of Securities of such series. If the form or terms of the
Securities of the series and the Guarantees endorsed thereon have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities and the Guarantees
endorsed thereon, and accepting the additional responsibilities under this
Indenture in relation to such Securities and the Guarantees endorsed thereon,
the Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

          (1) if the forms of such Securities and Guarantees have been
     established by or pursuant to Board Resolution as permitted by Section 201,
     that such forms have been established in conformity with the provisions of
     this Indenture;

          (2) if the terms of such Securities have been, or in the case of
     Securities of a series offered in a Periodic Offering, will be, established
     by or pursuant to Board Resolution as permitted by Section 301, that such
     terms have been, or in the case of Securities of a series offered in a
     Periodic Offering, will be, established in conformity with the provisions
     of this Indenture, subject, in the case of Securities of a series offered
     in a Periodic Offering, to any conditions specified in such Opinion of
     Counsel; and

          (3) that such Securities and the Guarantees endorsed thereon, when
     authenticated and delivered by the Trustee and issued by the Corporation
     and the Guarantor in the manner and subject to any conditions specified in
     such Opinion of Counsel, will constitute valid and legally binding
     obligations of the Corporation and the Guarantor 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 and 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, the Guarantor 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.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Corporation and the Guarantor
of any of such Securities and Guarantees, the forms and terms thereof and the
legality, validity, binding effect and enforceability thereof, upon the Opinion
of Counsel and the other documents delivered pursuant to Sections 201 and 301
and this Section, as applicable, in connection with the first authentication of
Securities of such series, with the Guarantees endorsed thereon.

                                       24
<PAGE>
 
     Each Security and any Guarantee endorsed thereon shall each be dated the
date of its authentication.

     No Security or Guarantee endorsed thereon 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 of an
authorized officer, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security or Guarantee endorsed
thereon has been duly authenticated and delivered hereunder.  Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Corporation, and the Corporation
shall deliver such Security to the Trustee for cancellation as provided in
Section 309, for all purposes of this Indenture such Security (including any
Guarantee endorsed thereon) shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this
Indenture.

Section 304.  Temporary Securities.
              --------------------

     Pending the preparation of definitive Securities of any series, the
Corporation may execute, and upon Company Order and Guarantor 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, having Guarantees endorsed thereon, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities or Guarantees may determine, as evidenced by
their execution of such Securities or Guarantees.

     If temporary Securities of any series are issued, the Corporation 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, with the definitive Guarantees of the Guarantor
endorsed thereon, upon surrender of the temporary Securities of such series at
the office or agency of the Corporation in a Place of Payment for that series,
without charge to the Holder.  Upon surrender for cancellation of any one or
more temporary Securities of any series, the Corporation shall execute and the
Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, with the definitive Guarantees of the
Guarantor endorsed thereon.  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 and tenor.

Section 305.  Registration, Registration of Transfer and Exchange.
              ---------------------------------------------------

     The Corporation shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office or in any other
office or agency of the Corporation in a Place of Payment being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Corporation shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed 

                                       25
<PAGE>
 
"Security 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
the office or agency of the Corporation in a Place of Payment for that series,
the Corporation 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 like tenor
and aggregate principal amount, with the Guarantees of the Guarantor endorsed
thereon.

     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 like
tenor and 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 Corporation shall execute, and the Trustee shall authenticate
and deliver, the Securities, with the Guarantees of the Guarantor endorsed
thereon, which the Holder making the exchange is entitled to receive.

     All Securities and Guarantees issued upon any registration of transfer or
exchange of Securities and the Guarantees endorsed thereon shall be the valid
obligations of the Corporation and the Guarantor, respectively, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities and Guarantees 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 Corporation, the Guarantor or the Trustee)
be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Corporation, the Guarantor and the Security Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

     No service charge shall be assessed against the Holder for any registration
of transfer or exchange of Securities, but the Corporation 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 1106 not
involving any transfer.

     If the Securities of any series (or of any series and specified tenor) are
to be redeemed, the Corporation shall not be required (A) 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 selected for redemption and ending at the close of business on
the day of such mailing, or (B) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

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

                                       26
<PAGE>
 
          (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 has notified the
     Corporation that it is unwilling or unable to continue as Depositary for
     such Global Security and a successor Depositary has not been appointed by
     the Corporation within 90 days of receipt by the Corporation of such
     notification, (B) if at any time the Depositary ceases 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 and no successor
     Depositary shall have been appointed by the Corporation within 90 days
     after it became aware of such cessation, or (C) 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.
     Notwithstanding the foregoing, the Corporation may at any time in its sole
     discretion determine that Securities issued in the form of a Global
     Security shall no longer be represented in whole or in part by such Global
     Security, and the Trustee, upon receipt of a Company Order therefor, shall
     authenticate and deliver definitive Securities in exchange in whole or in
     part for such Global Security.

          (3) Subject to Clause (2) above, any exchange or transfer of a Global
     Security for other Securities may be made in whole or in part, and all
     Securities issued in exchange for or upon transfer of 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
     1106 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 Corporation
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, having a Guarantee of the Guarantor endorsed thereon and bearing a
number not contemporaneously outstanding.

     If there shall be delivered to the Corporation, the Guarantor 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

                                       27
<PAGE>
 
harmless, then, in the absence of notice to the Corporation, the Guarantor or
the Trustee that such Security has been acquired by a bona fide purchaser, the
Corporation 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, having a Guarantee of the
Guarantor endorsed thereon 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 Corporation or the Guarantor in its
discretion may, instead of issuing a new Security, pay such Security.

     Upon the issuance of any new Security under this Section, the Corporation
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 (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 and any Guarantee endorsed thereon shall
constitute an original additional contractual obligation of the Corporation and
the Guarantor, respectively, 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 and the Guarantees
endorsed on such Securities.

     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.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of Securities, 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 Corporation or
the Guarantor, at its election in each case, as provided in Clause (1) or (2)
below:

          (1) The Corporation or the Guarantor 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
     Corporation or the Guarantor shall notify the Trustee in writing 

                                       28
<PAGE>
 
     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
     Corporation or the Guarantor, as the case may be, 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 Corporation and the
     Guarantor of such Special Record Date and, in the name and at the expense
     of the Corporation or the Guarantor, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be given to each Holder of Securities of such series in the manner set
     forth in Section 106, 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 Corporation or the Guarantor 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, if any, on
     which such Securities may be listed, and upon such notice as may be
     required by such exchange, if, after notice given by the Corporation or the
     Guarantor 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 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, which were carried by such other Security.

Section 308.  Persons Deemed Owners.
              ---------------------

     Prior to due presentment of a Security for registration of transfer, the
Corporation, the Guarantor, the Trustee and any agent of the Corporation, the
Guarantor or the Trustee may 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 any premium and (subject to Section 307) any interest on such
Security and for all other purposes whatsoever, whether or not such Security be
overdue, and none of the Corporation, the Guarantor, the Trustee or any agent of
the Corporation, the Guarantor 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 or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Corporation or the Guarantor may at
any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Corporation or the Guarantor may
have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Corporation has not issued and
sold, and all Securities so delivered shall be promptly canceled by the Trustee.
No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section, except as expressly permitted
by this Indenture.  All canceled Securities held by the Trustee shall be
disposed of as directed by a Company Order; provided, however, that the Trustee
shall not be required to destroy such canceled Securities.

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.

Section 311.  CUSIP Numbers.
              -------------

     The Corporation in issuing the Securities 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.

          in a written certification thereof delivered to the Trustee, to pay
          and discharge, and which shall be applied by the Trustee to pay and
          discharge, the entire indebtedness on such Securities not theretofore

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

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

issued or has been deleted or modified in an indenture supplemental hereto:

          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 60 days; provided, however, that if the Corporation is
     permitted by the terms of the Securities of such series to defer the
     payment in question, the date on which such payment is due and payable
     shall be the date on which the Corporation is required to make payment
     following such deferral, if such deferral has been elected pursuant to the
     terms of the Securities; or

          (2) default in the payment of the principal of or any premium on any
     Security of that series at its Maturity; or

          (3) default in the making of any sinking fund payment, when and as due

     for a period of 60 days; or

     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and continuance of such default or breach for a period of 90 days
     after there has been given, by registered or certified mail, to the
     Corporation and the Guarantor by the Trustee or to the Corporation, the
     Guarantor and the Trustee by the

     of that series a written notice specifying such default or breach and
     requiring it to be remedied and stating that such notice is a "Notice of
     Default" hereunder, unless the Trustee, or the Trustee and the Holders of a
     principal amount of Securities of such series not less than the principal
     amount of Securities the Holders of which gave such notice, as the case may
     be, shall agree in writing to an extension of such period prior to its
     expiration; or

          (5) the cessation of effectiveness of the Guarantee endorsed on a
     Security of such series or the finding by any judicial proceeding that the
     Guarantee endorsed on a Security of such series is unenforceable or invalid
     or the denial or disaffirmation by the Guarantor of its obligations under
     the Guarantee endorsed on a Security of such series; or

          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Corporation or the Guarantor
     in an involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or (B) a decree
     or order adjudging the Corporation or the Guarantor a bankrupt or
     insolvent, or approving as properly filed a petition seeking
     reorganization, arrangement, adjustment or composition of or in respect of
     the Corporation or the Guarantor under any applicable federal or state law,

     sequestrator or other similar official of the Corporation or the Guarantor
     or of any substantial part of its property, or ordering the winding-up or
     liquidation of its affairs, and the continuance of any such decree or order
     for relief or any such other decree or order unstayed and in effect for a
     period of 90 consecutive days; or

          (7) the commencement by the Corporation or the Guarantor of a
     voluntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or of any other
     case or proceeding to be adjudicated a bankrupt or insolvent, or the
     consent by the Corporation or the Guarantor to the entry of a decree or
     order for relief in respect of the Corporation or the Guarantor in an
     involuntary case or proceeding under any applicable federal or state
     bankruptcy, insolvency, reorganization or other similar law or to the
     commencement of any bankruptcy or insolvency case or proceeding against the
     Corporation or the Guarantor, or the filing by it of a petition or answer
     or consent seeking reorganization or relief under any applicable federal or
     state law, or the consent by the Corporation or the Guarantor to the filing
     of such petition or to the appointment of or taking possession by a

     part of its property, or the making by the Corporation or the Guarantor of
     an assignment for the benefit of creditors, or the admission by the
     Corporation or the Guarantor in writing of its inability to pay its debts
     generally as they

                                       33
<PAGE>
 
     become due, or the authorization of any such action by the Board of
     Directors of the Corporation or the Guarantor; or

          (8) any other Event of Default provided with respect to Securities of
     that series.

Section 502.  Acceleration of Maturity; Rescission and Annulment.
              --------------------------------------------------

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Corporation (and to the Trustee if given by Holders), and upon
any such declaration such principal amount (or specified amount) shall become
immediately due and payable.

     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Event of Default giving rise to such declaration of
acceleration shall, without further act, be deemed to have been waived, and such
declaration and its consequences shall, without further act, be deemed to have
been rescinded and annulled, if

          (1) the Corporation or the Guarantor has paid or deposited with the
     Trustee a sum sufficient to pay

               (A) all overdue interest on all Securities of that series,

               (B) the principal of (and premium, if any, on) any Securities of
          that series which have become due otherwise than by such declaration
          of acceleration and any interest thereon at the rate or rates
          prescribed therefor in such Securities,

               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

               (D) 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 non-payment 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.

                                       34
<PAGE>
 
     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 Corporation and the Guarantor covenant that if

          (1) default is made in the payment of any interest on any Security
     when such interest becomes due and payable and such default continues for a
     period of 60 days, or

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

the Corporation or the Guarantor 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 any premium and interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal and premium and on any overdue interest, at the rate or
rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses 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 effectual 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 relative to the Corporation or the
Guarantor (or any other obligor upon the Securities), their property or their
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,

                                       35
<PAGE>
 
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; provided, however, that the Trustee may, on
behalf of the Holders, vote for the election of a trustee in bankruptcy or
similar official and be a member of a creditors' or other similar committee.

Section 505.  Trustee May Enforce Claims Without Possession of Securities.
              -----------------------------------------------------------

     All rights of action and claims under this Indenture, the Securities or the
Guarantees endorsed thereon 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.
              ------------------------------

     Any money 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 any premium
or 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 any premium and 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 any premium and interest,
     respectively; and

          Third:  To the payment of the balance, if any, to the Corporation or
     any other Person or Persons legally entitled thereto.

Section 507.  Limitation on Suits.
              -------------------

     No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

          (1) such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;

                                       36
<PAGE>
 
          (2) the Holders of not less than a majority in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (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;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

              ----------------------------------------------------------------
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 any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities 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 Corporation, the Guarantor, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder
and thereafter all rights and remedies of the Trustee and the Holders shall
continue as though no such proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.
              ------------------------------

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the 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

                                       37
<PAGE>
 
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 Securities 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, with respect to the Securities of
such series; provided that

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

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

          (3) subject to the provisions of Section 601, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability.

Section 513.  Waiver of Past Defaults.
              -----------------------

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of all series with respect to which any default under the
Indenture shall have occurred and be continuing (voting as one class) may, on
behalf of the Holders of all Securities of all such series, waive such past
default under the Indenture and its consequences, except a default

          (1) in the payment of the principal of or any premium or interest on
     any Security of such series, or

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

                                       38
<PAGE>
 
     Upon any such waiver, such default shall cease to exist and be deemed not
to have occurred, and any Event of Default arising therefrom shall be deemed to
have been cured and not to have occurred, 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 suit 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 Corporation, the Guarantor or
the Trustee.

Section 515.  Waiver of Stay or Extension Laws.
              --------------------------------

     Each of the Corporation and the Guarantor 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 each of the
Corporation and the Guarantor (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 VI.

                                  THE TRUSTEE

Section 601.  Certain Duties and Responsibilities.
              -----------------------------------

     The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. 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. The permissive right of
Trustee to do things enumerated in this Indenture shall not be construed as a
duty to do such things and in no event shall the Trustee be liable for the
consequences of any act or omission except to the extent of Trustee's gross
negligence or willful misconduct. 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 a default known to the Trustee 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

                                       39
<PAGE>
 
specified in Section 501(4) with respect to Securities of such series, no such
notice to Holders shall be given until at least 30 days after the occurrence
thereof. 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.

Section 603.  Certain Rights of Trustee.
              -------------------------

     Subject to the provisions of Section 601:

          (1) the Trustee may rely and shall be 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 or presented
     by the proper party or parties;

          (2) any request or direction of the Corporation or the Guarantor
     mentioned herein shall be sufficiently evidenced by a Company Request or
     Company Order, or a Guarantor Request or a Guarantor Order, or as otherwise
     expressly provided herein, and any resolution of the Board of Directors
     shall be sufficiently evidenced by a Board Resolution;

          (3) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to 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 of the Corporation or
     the Guarantor, as appropriate;

          (4) the Trustee may consult with counsel of its selection and the
     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;

          (5) prior to the occurrence of an Event of Default, the Trustee shall
     undertake to perform only such duties as are specifically set forth in this
     Indenture; and in case an Event of Default has occurred and is continuing,
     the Trustee shall be under no obligation to exercise any of the rights or
     powers vested in it by this Indenture whether at the request or direction
     of any of the Holders or pursuant to any other provision in this Indenture,
     unless such Holders shall have offered to the Trustee reasonable security
     or indemnity against the costs, expenses and liabilities which might be
     incurred by it;

          (6) 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, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled, at reasonable times previously notified to the
     Corporation or the Guarantor, to examine the

                                       40
<PAGE>
 
     relevant books, records and premises of the Corporation or the Guarantor,
     personally or by agent or attorney; and

          (7) 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.

Section 604.  Not Responsible for Recitals or Issuance of Securities.
              ------------------------------------------------------

     The recitals contained herein and in the Securities and the Guarantees
endorsed thereon, except the Trustee's certificates of authentication, shall be
taken as the statements of the Corporation or the Guarantor, as the case may be,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness.  The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities or the Guarantees endorsed
thereon.  Neither the Trustee nor any Authenticating Agent shall be accountable
for the use or application by the Corporation of Securities or the proceeds
thereof.

Section 605.  May Hold Securities.
              -------------------

     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Corporation, 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 Corporation with the same rights it
would have if it were not Trustee, Authenticating Agent, 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 from
other funds except to the extent required by law.  The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing by the Trustee with the Corporation or the Guarantor.

Section 607.  Compensation, Reimbursement and Indemnity
              -----------------------------------------

     The Corporation and the Guarantor jointly and severally agree

          (1) to pay to the Trustee from time to time such compensation as shall
     be agreed to in writing between the Corporation and the Trustee 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
     of this Indenture (including the reasonable compensation and the expenses
     and disbursements of its agents and counsel),

                                       41
<PAGE>
 
     except any such expense, disbursement or advance as may be attributable to
     its negligence, willful misconduct or bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence, willful misconduct
     or bad faith on its part, arising out of or in connection with the
     acceptance or administration of the trust or trusts hereunder, 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 shall have a first priority lien prior to the Securities upon
all property and funds held by it hereunder for any amount owing it or any
predecessor Trustee pursuant to this Section 607, except with respect to funds
held in trust for the benefit of the Holders of particular Securities.

     Without limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of Default specified in Section 501(5) or Section 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

     The provisions of this Section shall survive the termination of this
Indenture.

Section 608.  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 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 condition at
least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent
permitted by the Trust Indenture Act, the combined capital and surplus of such
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 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.

                                       42
<PAGE>
 
Section 610.  Resignation and Removal; Appointment of Successor.
              -------------------------------------------------

     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 the successor Trustee in accordance with the applicable
requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or
more series by giving written notice thereof to the Corporation and the
Guarantor.  If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 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.

     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, the Corporation
and the Guarantor.

     If at any time:

          (1) the Trustee shall fail to comply with Section 608 after written
     request therefor by the Corporation, the Guarantor 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 Corporation, the
     Guarantor 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,

then, in any such case, (A) the Corporation and the Guarantor by Board
Resolutions may remove the Trustee with respect to all Securities, or (B)
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 himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

     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 Corporation and the Guarantor, by
Board Resolutions, 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) and shall comply with
the applicable requirements of Section 611.  If, within one year after such
resignation, removal or incapability, or the occurrence

                                       43
<PAGE>
 
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 Corporation
and the retiring Trustee, the successor Trustee so appointed shall, forthwith
upon its acceptance of such appointment in accordance with the applicable
requirements of Section 611, become the successor Trustee with respect to the
Securities of such series and to that extent supersede the successor Trustee
appointed by the Corporation and the Guarantor. If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Corporation and the Guarantor or the Holders and accepted appointment in the
manner required by Section 611, 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.

     The Corporation 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 name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

Section 611.  Acceptance of Appointment by Successor.
              --------------------------------------

     In case of the appointment hereunder of a successor Trustee with respect to
all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Corporation, the Guarantor and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation
or removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee; but, on the
request of the Corporation, the Guarantor or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder (subject to the lien provided for on Section 607).

     In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Corporation, the
Guarantor, 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

                                       44
<PAGE>
 
Trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees co-trustees of the same trust and that
each such Trustee shall be trustee of a trust or trusts hereunder separate and
apart from any trust or 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 Corporation, the Guarantor 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 Corporation and the
Guarantor 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.
              -----------------------------------------------------------

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, 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.

Section 613.  Preferential Collection of Claims Against Corporation.
              -----------------------------------------------------

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

Section 614.  Appointment of Authenticating Agent.
              -----------------------------------

     The Trustee may appoint an Authenticating Agent or Agents acceptable to the
Corporation with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration

                                       45
<PAGE>
 
of transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Corporation and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by federal or state authority. If such
Authenticating Agent 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, the combined capital and surplus of such
Authenticating Agent 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 an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent 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 Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided that such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee, the Corporation and the Guarantor.  The Trustee may at
any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent, the Corporation and the Guarantor.
Upon receiving such a notice of resignation or upon such a termination, or in
case at any time such Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, the Trustee may appoint a
successor Authenticating Agent which shall be acceptable to the Corporation and
the Guarantor and shall give notice of such appointment in the manner provided
in Section 106 to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve.  Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent.  No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

     The Corporation and the Guarantor, jointly and severally, agree to pay to
each Authenticating Agent from time to time reasonable compensation for its
services under this Section.

     If an appointment with respect to one or more series is made pursuant to
this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative

     The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding
rights and privileges of the Trustee, shall be as provided by the Trust
Indenture Act.

     Every Holder of Securities, by receiving and holding the same, agrees with

Indenture Act at the times and in the manner provided pursuant to such Act;
provided that any such information, documents or reports required to be filed

filed with the Trustee within 15 days after the same is so required to be filed
with the Commission. Delivery of such reports, information and documents to the

parties, or shall prevent any conveyance or transfer of the properties and
assets of the Corporation or the Guarantor as an entirety or substantially as an
entirety to any other Person (whether or not affiliated with the Corporation or
the Guarantor) lawfully entitled to acquire the same; provided, however, that
upon any such consolidation or

interest on all of the Securities, according to their tenor, and the due and
punctual performance and observance of all of the covenants and conditions of

satisfactory to the Trustee, executed and delivered to the Trustee by the Person
(if other than the Corporation or the Guarantor) formed by such consolidation,
or into which the Corporation or the Guarantor shall have been merged, or by the
Person which shall have acquired such properties and assets from the Guarantor,

that such consolidation, merger, conveyance or transfer and, if a supplemental
indenture is required in connection with such transaction, such supplemental
indenture comply with this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

of the Corporation or the Guarantor into, any other Person or any conveyance or

covenants under this Indenture and the Securities or the Guarantees endorsed
thereon, as the case may be.

Section 901.  Supplemental Indentures Without Consent of Holders.
              --------------------------------------------------

     Without the consent of any Holders, the Corporation and the Guarantor, when
authorized by Board Resolutions, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
reasonably satisfactory to the Trustee, for any of the following purposes:

          (1) to evidence the succession of another Person to the Corporation or
     the Guarantor, as the case may be, and the assumption by any such successor
     of the covenants of the Corporation or the Guarantor, as the case may be,
     herein and in the Securities or the Guarantees endorsed thereon; or

                                       49
<PAGE>
 
          (2) to add to the covenants of the Corporation or the Guarantor for
     the benefit of the Holders of all or any series of Securities (and if such
     covenants are to be for the benefit of less than all series of Securities,
     stating that such covenants are expressly being included solely for the
     benefit of such series) or to surrender any right or power herein conferred
     upon the Corporation or the Guarantor; or

          (3) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such additional Events
     of Default are to be for the benefit of less than all series of Securities,
     stating that such additional Events of Default are expressly being included
     solely for the benefit of such series); or

          (4) to add to or change any of the provisions of this Indenture to
     such extent as shall be necessary to permit or facilitate the issuance of
     Securities in bearer form, registrable or not registrable as to principal,
     and with or without interest coupons, or to facilitate the issuance of
     Securities in uncertificated form; or

          (5) to add to, change or eliminate any of the provisions of this
     Indenture in respect of one or more series of Securities; provided that any
     such addition, change or elimination (A) shall neither (i) apply to any
     Security of any series created prior to the execution of such supplemental
     indenture and entitled to the benefit of such provision nor (ii) modify the
     rights of the Holder of any such Security with respect to such provision or
     (B) shall become effective only when there is no such Security Outstanding;
     or

          (6) to secure the Securities; or

          (7) to establish the form or terms of Securities of any series or any
     Guarantees as permitted by Sections 201 and 301; or

          (8) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to 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, pursuant to the requirements
     of Section 611; or

          (9) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture; provided that such action pursuant
     to this Clause (9) shall not adversely affect the interests of the Holders
     of Securities of any series in any material respect.

Section 902.  Supplemental Indentures With Consent of Holders.
              -----------------------------------------------

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of all series affected by such supplemental
indenture (voting as one class), by Act of said Holders delivered to the
Corporation, the Guarantor and the Trustee, the Corporation and the Guarantor,
when authorized by Board Resolutions, and the Trustee may

                                       50
<PAGE>
 
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture, or modifying in
any manner the rights of the Holders of Securities under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby,

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security or any other Security which would be due
     and payable upon a declaration of acceleration of the Maturity thereof
     pursuant to Section 502 or change the coin or currency in which any
     Security or any premium or interest thereon is payable, or impair the right
     to institute suit for the enforcement of any such payment on or after the
     Stated Maturity thereof (or, in the case of redemption, on or after the
     Redemption Date), or

          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or

          (3) modify any of the provisions of this Section, Section 513 or
     Section 1006, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
     the consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section and Section 1006, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611 and 901(8).  A supplemental indenture which changes or eliminates any
     covenant or other provision of this Indenture which has expressly been
     included solely for the benefit of one or more particular series of
     Securities, or which modifies the rights of the Holders of Securities of
     such series with respect to such covenant or other provision, shall be
     deemed not to affect the rights under this Indenture of the Holders of
     Securities of any other series.

     It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

Section 903.  Execution of Supplemental Indentures.
              ------------------------------------

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture.  The Trustee may, but shall not be
obligated to, enter

                                       51
<PAGE>
 
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

Section 904.  Effect of Supplemental Indentures.
              ---------------------------------

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

Section 905.  Conformity with Trust Indenture Act.
              -----------------------------------

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.

Section 906.  Reference in Securities to Supplemental Indentures.
              --------------------------------------------------

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Corporation and the
Guarantor shall so determine, new Securities of any series so modified as to
conform, in the opinion of the Trustee, the Corporation and the Guarantor, to
any such supplemental indenture may be prepared and executed by the Corporation
(with Guarantees of the Guarantor endorsed thereon) and authenticated and
delivered by the Trustee in exchange for Outstanding Securities of such series.

                                  ARTICLE X.

                                   COVENANTS

Section 1001.  Payment of Principal, Premium and Interest.
               ------------------------------------------

     The Corporation covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
the Securities and this Indenture.

Section 1002.  Maintenance of Office or Agency.
               -------------------------------

     The Corporation and the Guarantor will maintain in each Place of Payment
for any series of Securities an office or agency 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 and where notices and
demands to or upon the Corporation or the Guarantor in respect of the Securities
of that series and this Indenture may be served.  The Corporation and the
Guarantor 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
Corporation or the Guarantor shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address

                                       52
<PAGE>
 
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Corporation and the
Guarantor hereby appoint the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Corporation or the Guarantor may also from time to time designate one
or more other offices or agencies 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 Corporation or the Guarantor of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes.  The Corporation and the Guarantor
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 Securities Payments to Be Held in Trust.
               -------------------------------------------------

     If the Corporation shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium 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 and any premium and 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 Corporation shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium 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 Corporation will promptly notify the Trustee of its action or
failure so to act.

     The Corporation will cause each Paying Agent for any series of Securities
other than the Trustee 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, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Corporation (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 for payment in
respect of the Securities of that series.

     The Corporation 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 hereunder by the Corporation 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
Corporation 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.

                                       53
<PAGE>
 
     Subject to any applicable escheatment laws, any money deposited with the
Trustee or any Paying Agent, or then held by the Corporation, in trust for the
payment of the principal of or any premium or interest on any Security of any
series and remaining unclaimed for two years after such principal, premium or
interest has become due and payable shall be paid to the Corporation on Company
Request, or (if then held by the Corporation) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Corporation and the Guarantor for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Corporation as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Corporation cause
to be published once, in a newspaper published in the English language,
customarily published on each Business Day and of general circulation in the
Borough of Manhattan, The City of New York, New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Corporation.

Section 1004.  Corporate Existence.
               -------------------

     Subject to Article Eight, the Corporation and the Guarantor will do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, rights (charter and statutory) and franchises.

Section 1005.  Statement by Officers as to Default.
               -----------------------------------

     Each of the Corporation and the Guarantor will deliver to the Trustee, on
or before October 15 of each calendar year or on or before such other day in
each calendar year as the Corporation, the Guarantor and the Trustee may from
time to time agree upon, an Officers' Certificate, stating whether or not to the
best knowledge of the signers thereof the Corporation or the Guarantor, as the
case may be, is in default in the performance and observance of any of the
terms, provisions and conditions of this Indenture (without regard to any period
of grace or requirement of notice provided hereunder) and, if the Corporation or
the Guarantor shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

Section 1006.  Waiver of Certain Covenants.
               ---------------------------

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series, the Corporation may, with respect to the Securities of any
series, omit in any particular instance to comply with any term, provision or
condition set forth in any covenant provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such series if before the time for
such compliance the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of

                                       54
<PAGE>
 
the Corporation and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

                                  ARTICLE XI.

                           REDEMPTION OF SECURITIES

Section 1101.  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 1102.  Election to Redeem; Notice to Trustee.
               -------------------------------------

     The election of the Corporation to redeem any Securities 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
Corporation, the Corporation shall, at least 45 days prior to the Redemption
Date fixed by the Corporation (unless a shorter notice shall be satisfactory to
the Trustee), notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the
tenor of the Securities to be redeemed.  In the case of any redemption of
Securities (A) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, or (B)
pursuant to an election of the Corporation which is subject to a condition
specified in the terms of such Securities or elsewhere in this Indenture, the
Corporation and the Guarantor shall each furnish the Trustee with an Officers'
Certificate evidencing compliance with any such restriction or condition
applicable to it.

Section 1103.  Selection by Trustee of Securities to Be Redeemed.
               -------------------------------------------------

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series; provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.  If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

                                       55
<PAGE>
 
     The Trustee shall promptly notify the Corporation in writing of the
Securities selected for redemption as aforesaid and, in the 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 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 1104.  Notice of Redemption.
               --------------------

     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

     All notices of redemption shall state:

          (1) the Redemption Date;

          (2) the Redemption Price;

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

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

          (5) the place or places where each such Security is to be surrendered
     for payment of the Redemption Price and accrued interest, if any, unless it
     shall have been specified as contemplated by Section 301 with respect to
     such Securities that such surrender shall not be required;

          (6) that the redemption is for a sinking fund, if such is the case;
     and

          (7) such other matters as the Corporation shall deem desirable or
     appropriate.

                                       56
<PAGE>
 
     Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Corporation, unless, upon the giving of notice of such redemption,
Defeasance shall have been effected with respect to such Securities pursuant to
Section 1302, such notice may state that such redemption shall be conditional
upon the receipt by the Trustee or the Paying Agent(s) for such Securities, on
or prior to the date fixed for such redemption, of money sufficient to pay the
principal of and any premium and interest on such Securities and that if such
money shall not have been so received such notice shall be of no force or effect
and the Corporation shall not be required to redeem such Securities.  In the
event that such notice of redemption contains such a condition and such money is
not so received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

     Notice of redemption of Securities to be redeemed at the election of the
Corporation, and any notice of non-satisfaction of redemption as aforesaid,
shall be given by the Corporation or, at the Corporation's request, by the
Trustee in the name and at the expense of the Corporation.  Subject to the
preceding paragraph, any such notice of redemption shall be irrevocable.

Section 1105.  Securities Payable on Redemption Date.
               -------------------------------------

     Notice of redemption having been given as aforesaid, and the conditions, if
any, set forth in such notice having been satisfied, the Securities or portions
thereof 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 (unless,
in the case of an unconditional notice of redemption, the Corporation shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities or portions thereof, if interest-bearing, shall cease to bear
interest.  Upon surrender of any such Security for redemption in accordance with
said notice, such Security or portion thereof shall be paid by the Corporation
at the Redemption Price, together with accrued interest, if any, to the
Redemption Date; provided, however, that no such surrender shall be a condition
to such payment if so specified as contemplated by Section 301 with respect to
such Security, and provided further that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will 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.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

                                       57
<PAGE>
 
Section 1106.  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 Corporation, the Guarantor or the
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Corporation, the Guarantor and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing), and
the Corporation shall execute, and the Trustee shall authenticate and deliver to
the Holder of such Security without a service charge levied against the Holder,
a new Security or Securities of the same series and of like tenor, 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, with the Guarantee of the Guarantor endorsed
thereon.

                                 ARTICLE XII.

                                 SINKING FUNDS

Section 1201.  Applicability of Article.
               ------------------------

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment," and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund payment."  If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to reduction as provided in Section 1202.  Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

Section 1202.  Satisfaction of Sinking Fund Payments with Securities.
               -----------------------------------------------------

     The Corporation (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Corporation pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to any Securities of such series required to be made
pursuant to the terms of such Securities as and to the extent provided for by
the terms of such Securities; provided that the Securities to be so credited
have not been previously so credited.  The Securities to be so credited shall be
received and credited for such purpose by the Trustee at the Redemption Price,
as specified in the Securities so to be redeemed, for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

Section 1203.  Redemption of Securities for Sinking Fund.
               -----------------------------------------

     Not less than 45 days prior to each sinking fund payment date for any
Securities, the Corporation will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been previously so credited and will also deliver to the Trustee any
Securities to be so delivered.  Not less than 30 days prior to each such sinking
fund payment date, the Trustee shall select the Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Corporation in the manner provided in Section 1104.  Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1105 and 1106.

                                 ARTICLE XIII.

                      DEFEASANCE AND COVENANT DEFEASANCE

Section 1301.  Applicability of Article.
               ------------------------

     Unless, pursuant to Section 301, provision is made that either or both of
(A) defeasance of any Securities or any series of Securities under Section 1302
and (B) covenant defeasance of any Securities or any series of Securities under
Section 1303 shall not apply to such Securities of a series, then the provisions
of either or both of Sections 1302 and Section 1303, as the case may be,
together with Sections 1304 and 1305, shall be applicable to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article.

Section 1302.  Defeasance and Discharge.
               ------------------------

     On and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Defeasance"), the Corporation and the Guarantor
may cause themselves to be discharged from their obligations with respect to any
Securities or any series of Securities and the Guarantees endorsed thereon.  For
this purpose, such Defeasance means that the Corporation  shall be deemed to
have paid and discharged the entire indebtedness represented by such Securities
and the Corporation and the Guarantor shall be deemed to have satisfied all
other obligations under such Securities and the Guarantees endorsed thereon and
this Indenture insofar as such Securities and the Guarantees endorsed thereon
are concerned (and the Trustee, at the expense of the Corporation or the
Guarantor, shall execute proper instruments acknowledging the same), subject to
the following which shall survive until otherwise terminated or discharged
hereunder:  (1) the rights of Holders of such Securities to receive, solely from
the trust fund described in Section 1304 and as more fully set forth in such
Section, payments in respect of the principal of and any premium and interest on
such Securities when payments are due, (2) the Corporation's and Guarantor's
obligations with respect to such Securities and the Guarantees endorsed thereon
under Sections 304, 305, 306, 1002 and 1003 and with respect to the Trustee
under Section 607, (3) the rights, powers, trusts, duties and immunities of the
Trustee hereunder

                                       59
<PAGE>
 
and (4) this Article. Subject to compliance with this Article, Defeasance with
respect to any Securities or any series of Securities and the Guarantees
endorsed thereon by the Corporation and the Guarantor is permitted under this
Section 1302 notwithstanding the prior exercise by the Corporation of its rights
under Section 1303 with respect to such Securities. Following a Defeasance,
payment of such Securities may not be accelerated because of an Event of
Default.

Section 1303.  Covenant Defeasance.
               -------------------

     On and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"), the Corporation and the
Guarantor may cause themselves to be released from their obligations under any
covenants provided pursuant to Section 301(19), 901(2), 901(6) or 901(7) with
respect to any Securities or any series of Securities and the Guarantees
endorsed thereon for the benefit of the Holders of such Securities and the
occurrence of any event specified in Sections 501(4) (with respect to any such
covenants provided pursuant to Section 301(19), 901(2), 901(6) or 901(7)) or
501(7) shall be deemed not to be or result in an Event of Default with respect
to such Securities as provided in this Section.  For this purpose, such Covenant
Defeasance means that, with respect to such Securities and the Guarantees
endorsed thereon, the Corporation and the Guarantor may omit to comply with and
shall have no liability in respect of any term, condition or limitation set
forth in any such specified Section (to the extent so specified in the case of
Section 501(4)), whether directly or indirectly by reason of any reference
elsewhere herein to any such Section or by reason of any reference in any such
Section to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby.

Section 1304.  Conditions to Defeasance or Covenant Defeasance.
               -----------------------------------------------

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be,
and the Guarantees endorsed thereon:

          (1) The Corporation or the Guarantor shall irrevocably have deposited
     or caused to be deposited with the Trustee as trust funds in trust for the
     purpose of making the following payments, specifically pledged as security
     for, and dedicated solely to, the benefit of the Holders of such
     Securities, (A) money in an amount, or (B) Government Obligations which
     through the scheduled payment of principal and interest in respect thereof
     in accordance with their terms will provide, not later than the due date of
     any payment, money in an amount, or (C) a combination thereof, sufficient,
     in the case of (B) or (C), in the opinion of a nationally recognized firm
     of independent public accountants expressed in a written certification
     thereof delivered to the Trustee, to pay and discharge, and which shall be
     applied by the Trustee to pay and discharge, the principal of and any
     premium and interest on such Securities on the respective Stated Maturities
     or on any Redemption Date established pursuant to Clause (3) below, in
     accordance with the terms of this Indenture and such Securities.  As used
     herein, "Government Obligation" means (x) any security which is (i) a
     direct obligation of the United States of America or the government which
     issued the foreign currency in which

                                       60
<PAGE>
 
     such Securities are payable, for the payment of which its full faith and
     credit is pledged or (ii) an obligation of a Person controlled or
     supervised by and acting as an agency or instrumentality of the United
     States of America or such government which issued the foreign currency in
     which such Securities are payable, the payment of which is unconditionally
     guaranteed as a full faith and credit obligation by the United States of
     America or such other government, which, in either case (i) or (ii), is not
     callable or redeemable at the option of the issuer thereof, and (y) any
     depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
     Securities Act) as custodian with respect to any Government Obligation
     which is specified in clause (x) above and held by such bank for the
     account of the holder of such depositary receipt, or with respect to any
     specific payment of principal of or interest on any Government Obligation
     which is so specified and held, provided that (except as required by law)
     such custodian is not authorized to make any deduction from the amount
     payable to the holder of such depositary receipt from any amount received
     by the custodian in respect of the Government Obligation or the specific
     payment of principal or interest evidenced by such depositary receipt.

          (2) No event which is, or after notice or lapse of time or both would
     become, an Event of Default with respect to such Securities, any other
     Securities or any Guarantees endorsed thereon shall have occurred and be
     continuing at the time of such deposit or, with regard to any such event
     specified in Sections 501(5) and (6), at any time on or prior to the 90th
     day after the date of such deposit (it being understood that this condition
     shall not be deemed satisfied until after such 90th day).

          (3) If the Securities are to be redeemed prior to Stated Maturity
     (other than from mandatory sinking fund payments or analogous payments),
     notice of such redemption shall have been duly given pursuant to this
     Indenture or provision therefor satisfactory to the Trustee shall have been
     made.

          (4) The Corporation and the Guarantor shall have delivered to the
     Trustee an Officers' Certificate and an Opinion of Counsel, each stating
     that all conditions precedent with respect to such Defeasance or Covenant
     Defeasance have been complied with.

Section 1305.  Deposited Money and Government Obligations to Be Held in Trust;
               ---------------------------------------------------------------
               Miscellaneous Provisions.
               ------------------------

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 1304 in respect of any Securities shall be held in
trust and applied by the Trustee (subject to Trustee's Section 607 lien), in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the
Corporation acting as its own Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in respect
of principal and any premium and interest, but money so held in trust need not
be segregated from other funds except to the extent required by law.

     The Corporation or the Guarantor shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against the
Government Obligations deposited

                                       61
<PAGE>
 
pursuant to Section 1304 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of Outstanding Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Corporation from time to time upon Company Request any
money or Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

                                 ARTICLE XIV.

                                   GUARANTEE

Section 1401.  Guarantee.
               ---------

     The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee, and to the Trustee on
behalf of such Holder, the due and punctual payment of the principal of, and
premium, if any, and interest, if any, on the Securities of such series when and
as the same shall become due and payable, whether at the Stated Maturity, by
declaration of acceleration, call for redemption, or otherwise, in accordance
with the terms of such Security and of this Indenture.  In case of the failure
of the Corporation punctually to make any such payment, the Guarantor hereby
agrees to cause such payment to be made punctually when and as the same shall
become due and payable, whether at the Stated Maturity or by declaration of
acceleration, call for redemption or otherwise, and as if such payment were made
by the Corporation.

     The Guarantor hereby agrees that its obligations hereunder shall be
absolute and unconditional irrespective of, and shall be unaffected by, any
invalidity, irregularity or unenforceability of such Security or this Indenture,
any failure to enforce the provisions of such Security or this Indenture, or any
waiver, modification or indulgence granted to the Corporation with respect
thereto, by the Holder of such Security or the Trustee or any other circumstance
which may otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor; provided, however, that notwithstanding the foregoing, no
such waiver, modification or indulgence shall, without the consent of the
Guarantor, increase the principal amount of such Security, or increase the
interest rate thereon, or change any redemption provisions thereof (including
any change to increase any premium payable upon redemption thereof), or change
the Stated Maturity thereof, that would be due and payable upon a declaration of
acceleration or the maturity thereof pursuant to Article Eight of this
Indenture.

     The Guarantor hereby waives the benefits of diligence, presentment, demand
for payment, any requirement that the Trustee or any of the Holders exhaust any
right or take any action against the Corporation or any other Person, filing of
claims with a court in the event of insolvency or bankruptcy of the Corporation,
any right to require a proceeding first against the

                                       62
<PAGE>
 
Corporation, protest or notice with respect to any Security or the indebtedness
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged in respect of any Security except by complete performance
of the obligations contained in such Security and in this Guarantee. This
Guarantee shall constitute a guaranty of payment and not of collection. The
Guarantor hereby agrees that, in the event of a default in payment of principal,
or premium, if any, or interest, if any, on any Security, whether at its Stated
Maturity, by declaration of acceleration, call for redemption, or otherwise,
legal proceedings may be instituted by the Trustee on behalf of, or by, the
Holder of such Security, subject to the terms and conditions set forth in this
Indenture, directly against the Guarantor to enforce this Guarantee without
first proceeding against the Corporation.

     The obligations of the Guarantor hereunder with respect to any Security
shall be continuing and irrevocable until the date upon which the entire
principal of, premium, if any, and interest on such Security has been, or has
been deemed pursuant to the provisions of Article Seven of this Indenture to
have been, paid in full or otherwise discharged.

     The Guarantor shall be subrogated to all rights of the Holders of the
Securities upon which its Guarantee is endorsed against the Corporation in
respect of any amounts paid by the Guarantor on account of such Securities
pursuant to the provisions of its Guarantee or this Indenture; provided,
however, that the Guarantor shall not be entitled to enforce or to receive any
payments arising out of, or based upon, such right of subrogation until the
principal of, and premium, if any, and interest, if any, on all Securities
issued hereunder shall have been paid in full.

     This Guarantee shall remain in full force and effect and continue
notwithstanding any petition filed by or against the Corporation for liquidation
or reorganization, the Corporation becoming insolvent or making an assignment
for the benefit of creditors or a receiver or trustee being appointed for all or
any significant part of the Corporation's assets, and shall, to the fullest
extent permitted by law, continue to be effective or reinstated, as the case may
be, if at any time payment of any Security, is, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any
Holder of such Security, whether as a "voidable preference," "fraudulent
transfer," or otherwise, all as though such payment or performance had not been
made.  In the event that any payment, or any part thereof, is rescinded,
reduced, restored or returned on a Security, such Security shall, to the fullest
extent permitted by law, be reinstated and deemed paid only by such amount paid
and not so rescinded, reduced, restored or returned.

Section 1402.  Execution and Delivery of Guarantee.
               -----------------------------------

     The Guarantee to be endorsed on the Securities of each series shall include
the terms of the Guarantee set forth in Section 1401 and any other terms that
may be set forth as established pursuant to Section 301.  The Guarantor hereby
agrees to execute its Guarantee, in a form established pursuant to Section 201,
to be endorsed on each Security authenticated and delivered by the Trustee.

     The Guarantee shall be executed on behalf of the Guarantor by its Chairman
of the Board, Vice Chairman of the Board, President or a Vice President, under
its corporate seal reproduced

                                       63
<PAGE>
 
thereon attested by its Secretary or one of its Assistant Secretaries. The
signature of any such officer on the Guarantee may be manual or facsimile.

     A Guarantee bearing the manual or facsimile signature of an individual who
was at the time of execution a Chairman of the Board, Vice Chairman of the
Board, President or a Vice President of the Guarantor shall bind the Guarantor,
notwithstanding that any such individual has ceased to be a Chairman of the
Board, Vice Chairman of the Board, President or a Vice President of the
Guarantor prior to the authentication and delivery of the Security on which such
Guarantee is endorsed or was not a Chairman of the Board, Vice Chairman of the
Board, President or a Vice President of the Guarantor at the date of such
Guarantee.

     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the Guarantor.  The Guarantor hereby agrees that its
Guarantee set forth in Section 1401 shall remain in full force and effect
notwithstanding any failure to endorse a Guarantee on any Security.  The
Guarantor by its execution of this Indenture hereby authorizes the Corporation,
in the name and on behalf of the Guarantor, to confirm the applicable Guarantee
to the Holder of each Security authenticated and delivered hereunder by its
execution and delivery of each such Security, with such Guarantee endorsed
thereon, authenticated and delivered by the Trustee.

                                  ARTICLE XV.

                   IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                            OFFICERS AND DIRECTORS

Section 1501.  Indenture and Securities Solely Corporate Obligations.
               -----------------------------------------------------

     No recourse for the payment of the principal of or any premium or interest
on any Security, any Guarantees or any part thereof, or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Corporation or the Guarantor in this
Indenture or in any supplemental indenture, or in any Security, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, officer or director, as such, past, present or
future, of the Corporation, the Guarantor or of any successor corporation,
either directly or through the Corporation, the Guarantor or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this Indenture and
the issue of the Securities and the Guarantees endorsed thereon.

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

                                       64

     In Witness Whereof, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed and
attested, all as of the day and year first above written.

     facts;

                   (iii)   the Preferred Guarantee Trustee shall not be liable
     with respect to any action taken or omitted to be taken by it in good faith

     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;

                   (ix)    any action taken by the Preferred Guarantee Trustee
     or its agents hereunder shall bind the Trust and the Holders of the
     Preferred Securities and the signature of the Preferred Guarantee Trustee

     action; and no third party shall be required to inquire as to the authority
     of the Preferred Guarantee Trustee to so act, or as to its compliance with
     any of the terms and provisions of this Guarantee Agreement, both of which
     shall be conclusively evidenced by the Preferred Guarantee Trustee's or its
     agent's taking such action;

                   (x)     whenever in the administration of this Guarantee

     request instructions from the Holders of the Preferred Securities which

     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

     hereunder, and to each agent, custodian and other Person employed to act
     hereunder.

          (b)      No provision of this Guarantee Agreement shall be deemed to
empower the Preferred Guarantee Trustee to vary the investment of any Holder of
the Preferred Securities or to act in a manner inconsistent with the status of
the Issuer as a grantor trust for United States federal income tax purposes.

                   -----------   
shall be absolute and unconditional under any and all circumstances.

          There shall be no obligation on the Holders or any other Person to

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,

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

or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,

applicable law.

     (a) To the fullest extent permitted by applicable law, the Sponsor shall

damage or claim incurred by such Indemnified Person by reason of any act or
omission performed or omitted by such Indemnified Person in good faith on behalf

legal fees) incurred by an Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by the Sponsor
prior to the final disposition of such claim, demand, action, suit or proceeding

statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the

SECTION 4.3.  FIDUCIARY DUTY.

     (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for

         (i)   whenever a conflict of interest exists or arises between any

               herein or therein provides that an Indemnified Person shall act
               in a manner that is, or provides terms that are, fair and
               reasonable to the Trust or any holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.
<PAGE>
 
     (c) Whenever in this Declaration an Indemnified Person is permitted or
required to make a decision:

         (i)   in its "discretion" or under a grant of similar authority, the
               Indemnified Person shall be entitled to consider such interests
               and factors as it desires, including its own interests, and shall
               have no duty or obligation to give any consideration to any
               interest of or factors affecting the Trust or any other Person;
               or

         (ii)  in its "good faith" or under another express standard,

the Indemnified Person shall act under such express standard and shall not be
subject to any other or different standard imposed by this Declaration or by
applicable law.

SECTION 4.4.  INDEMNIFICATION.

     (a) To the fullest extent permitted by applicable law, the Sponsor shall
indemnify and hold harmless each Indemnified Person from and against any loss,
damage or claim incurred by such Indemnified Person by reason of any act or
omission performed or omitted by such Indemnified Person in good faith on behalf
of the Trust and in a manner such Indemnified Person reasonably believed to be
within the scope of authority conferred on such Indemnified Person by this
Declaration, except that no Indemnified Person shall be entitled to be
indemnified in respect of any loss, damage or claim incurred by such Indemnified
Person by reason of gross negligence or willful misconduct with respect to such
acts or omissions.

     (b) To the fullest extent permitted by applicable law, expenses (including
legal fees) incurred by an Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by the Sponsor
prior to the final disposition of such claim, demand, action, suit or proceeding
upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified
Person to repay such amount if it shall be determined that the Indemnified
Person is not entitled to be indemnified as authorized in Section 4.4(a).

SECTION 4.5.  OUTSIDE BUSINESSES.

     Any Covered Person, the Delaware Trustee and the Property Trustee may
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, similar or dissimilar to the business
of the Trust, and the Trust and the holders of Securities shall have no rights
by virtue of this Declaration in and to such independent ventures or the income
or profits derived therefrom and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper.  No Covered Person, the Property Trustee or the Delaware Trustee shall
be obligated to present any particular investment or other opportunity to the
Trust even if such opportunity is of a character that, if presented to the
Trust, could be taken by the Trust, and any Covered Person, the Property Trustee
and the Delaware Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity.

Securities may, by vote, on behalf of the Holders of all of the Preferred
Securities, waive any past Event of Default in respect of the Preferred
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                   (i)     is not waivable under the Indenture, the Event of
          Default under this Declaration shall also not be waivable; or

                   (ii)    requires the consent or vote of greater than a
          majority in principal amount of the holders of Subordinated Debt

316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the

Securities, as permitted by the Trust Indenture Act.  Upon such waiver, any such
default shall cease to exist, and any Event of Default with respect to the
Preferred Securities arising therefrom shall be deemed to have been cured, for
every purpose of this Declaration, but no such waiver shall extend to any
subsequent or other default or Event of Default with respect to the Preferred
Securities or impair any right consequent thereon.  Any waiver by the Holders of
the Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities.

          (b)      The Holders of a Majority in liquidation amount of the Common
Securities may, by vote, on behalf of the Holders of all of the Common

                                       7
<PAGE>
 
respect to the Common Securities and its consequences, provided that, if the
underlying Event of Default under the Indenture:

          Holders of the Common Securities are deemed to have waived such Event
          of Default under this Declaration as provided below in the proviso to
          this Section 2.6(b), the Event of Default under this Declaration shall
          also be not waivable; or

                   (ii)    requires the consent or vote of a Super Majority to
          be waived, except where the Holders of the Common Securities are
          deemed to have waived such Event of Default under this Declaration as
          provided below in the proviso to this Section 2.6(b), the Event of
          Default under this Declaration may only be waived by the vote of the
          Holders of at least the proportion in liquidation amount of the Common
          Securities which the relevant Super Majority represents of the
          aggregate principal amount of the Subordinated Debt Securities
          outstanding,

provided further, each Holder of Common Securities will be deemed to have waived
any such Event of Default and all Events of Default with respect to the Common
Securities and its consequences until all Events of Default with respect to the
Preferred Securities have been cured, waived or otherwise eliminated and until
such Events of Default have been so cured, waived or otherwise eliminated, the
Property Trustee will be deemed to be acting solely on behalf of the Holders of
the Preferred Securities and only the Holders of the Preferred Securities will
have the right to direct the Property Trustee in accordance with the terms of
the Securities; and provided, further, that any waiver by the Holders of the
Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holder of the Common Securities.  The foregoing provisions of
this Section 2.6(b) shall be in lieu of Section 316(a)(1)(A) and Section
316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(A) and
Section 316(a)(1)(B) of the Trust Indenture Act are hereby expressly excluded
from this Declaration and the Securities, as permitted by the Trust Indenture
Act.  Subject to the foregoing provisions of this Section 2.6(b), upon such
waiver, any such default shall cease to exist and any Event of Default with
respect to the Common Securities arising therefrom shall be deemed to have been
cured for every purpose of this Declaration, but no such waiver shall extend to
any subsequent or other default or Event of Default with respect to the Common
Securities or impair any right consequent thereon.

          (c)      A waiver of any Event of Default under the Indenture by the
Property Trustee at the direction of the Holders of the Preferred Securities
constitutes a waiver of the corresponding Event of Default with respect to the
Preferred Securities under this Declaration.  Any waiver of an Event of Default
under the Indenture by the Property Trustee at the direction of the Holders of
the Preferred Securities shall also be deemed to constitute a waiver by the
Holders of the Common Securities of the corresponding Event of Default under
this Declaration with respect to the Common Securities for all purposes of this
Declaration without further act, vote or consent of the Holders of the Common
Securities.  The foregoing provisions of this Section 2.6(c) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Declaration and
the Securities, as permitted by the Trust Indenture Act.

directors and/or Responsible Officers, of the Property Trustee in good faith
determine that the withholding of such notice is in the interests of the Holders
of the Securities.

any default except:

                   (i)     a default under Sections 501(1) and 501(2) of the
          Indenture; or

          have received written notice or of which a Responsible Officer of the
          Property Trustee charged with the administration of the Declaration
          shall have actual knowledge.

transfer agent for the Securities;

          (n)      to give prompt written notice to the Holders of the
Securities of any notice received from the Subordinated Debt Securities Issuer

          (o)      to take all action which may be necessary or appropriate for
the preservation and the continuation of the Trust's valid existence, rights,

     Section 3.7.  Prohibition of Actions by the Trust and the Trustees.
                   ---------------------------------------------------- 

          (a)      Notwithstanding any provision herein to the contrary, the
Trust shall not, and the Trustees (including the Property Trustee) shall cause
the Trust not to, engage in any activity other than as required or authorized by
this Declaration. In particular, the Trust shall not and the Trustees (including
the Property Trustee) shall cause the Trust not to:

                   (i)     invest any proceeds received by the Trust from
          holding the Subordinated Debt Securities, but shall distribute all
          such proceeds to Holders of Securities pursuant to the terms of this
          Declaration and of the Securities;

                   (ii)    acquire any assets other than the Subordinated Debt
          Securities and any cash proceeds received with respect thereto;

                   (iii)   possess Trust property for other than a Trust
          purpose;

<PAGE>
 
                   (iv)    make any loans or incur any indebtedness other than
          loans represented by the Subordinated Debt Securities;

                   (v)     possess any power or otherwise act in such a way as

          and Exhibit A hereto, (A) direct the time, method and place of
          exercising any trust or power conferred upon the Subordinated Debt
          Securities Trustee with respect to the Subordinated Debt Securities,

          termination of the Indenture or the Subordinated Debt Securities,
          where such consent shall be required, unless the Trust shall have
          received an opinion of counsel to the effect that such modification
          will not cause more than an insubstantial risk that for United States
          federal income tax purposes the Trust will not be classified as a
          grantor trust.

     Section 3.8.  Powers and Duties of the Property Trustee.
                   ----------------------------------------- 

          (a)      The legal title to the Subordinated Debt Securities shall be
owned by and held of record in the name of the Property Trustee for the benefit
of the Trust and the Holders of the Securities.  The right, title and interest
of the Property Trustee to the Subordinated Debt Securities shall vest
automatically in each Person who may hereafter be appointed as Property Trustee
as set forth in Section 5.6.  Such vesting and cessation of title shall be
effective whether or not conveyancing documents have been executed and
delivered.

          (b)      The Property Trustee shall not transfer its right, title and
interest in the Subordinated Debt Securities to the Regular Trustees or to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

          (c)      The Property Trustee shall:

                   (i)     establish and maintain a segregated non-interest
          bearing bank account (the "Property Trustee Account") in the name of
          and under the exclusive control of the Property Trustee on behalf of
          the Trust and the Holders of the Securities and, upon the receipt of
          payments of funds made in respect of the Subordinated Debt Securities
          held by the Property Trustee, deposit such funds into the Property
          Trustee Account and make payments to the Holders of the Preferred
          Securities and the Common Securities from the Property Trustee Account
          in accordance with Section 6.1. Funds in the Property Trustee Account
          shall be held uninvested until disbursed in accordance with this
          Declaration. The Property Trustee Account shall be an account which is
          maintained with a banking institution the rating on whose long term
          unsecured indebtedness is at least equal to the rating assigned to the
          Preferred Securities by a "nationally recognized statistical rating
          organization," as that term is defined for purposes of Rule 436(g)(2)
          under the Securities Act;

                                      14
<PAGE>
 
                   (ii)    engage in such ministerial activities as shall be
          necessary or appropriate to effect the redemption of the Preferred
          Securities and the Common Securities to the extent the Subordinated
          Debt Securities are redeemed or mature; and

                   (iii)   upon notice of distribution issued by the Regular
          Trustees in accordance with the terms of the Preferred Securities and
          the Common Securities, engage in such ministerial activities as shall
          be necessary or appropriate to effect the distribution of the
          Subordinated Debt Securities to Holders of Securities upon the
          Sponsor's election to dissolve the Trust in accordance with Section
          8.1(a)(v).

          (d)      The Property Trustee shall take all actions and perform such
duties as may be specifically required of the Property Trustee pursuant to the
terms of the Securities and this Declaration.

          (e)      The Property Trustee shall have the power to take any Legal
Action which arises out of or in connection with an Event of Default or the
Property Trustee's duties and obligations under this Declaration, the Business
Trust Act or the Trust Indenture Act.  If the Property Trustee fails to enforce
its rights under the Subordinated Debt Securities after a Holder of Preferred
Securities has made a written request, such Holder may, to the fullest extent
permitted by law, institute a legal proceeding against the Subordinated Debt
Securities Issuer, to enforce the Property Trustee's rights under the
Subordinated Debt Securities, without first instituting any legal proceeding
against the Property Trustee or any other Person.  Notwithstanding the
foregoing, if an Event of Default has occurred and is continuing and such event
is attributable to the failure of the Subordinated Debt Securities Issuer to pay
interest, premium, if any, or principal on the Subordinated Debt Securities on
the date such interest, premium, if any, or principal is otherwise payable (or
in the case of redemption, on the redemption date), then a Holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such Holder of the principal of, premium, if any, or interest on, the
Subordinated Debt Securities having a principal amount equal to the aggregate
liquidation amount of the Preferred Securities of such Holder (a "Direct
Action").  Notwithstanding any payments made to such Holder of Preferred
Securities by the Subordinated Debt Securities Issuer in connection with a
Direct Action, the Subordinated Debt Securities Issuer shall remain obligated to
pay the principal of, premium, if any, or interest on the Subordinated Debt
Securities held by the Trust or the Property Trustee of the Trust, and the
Subordinated Debt Securities Issuer shall be subrogated to the rights of the
Holder of such Preferred Securities with respect to payments on the Preferred
Securities.  Except as provided in the preceding sentences and in the Preferred
Securities Guarantee, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Subordinated
Debt Securities.

          (f)      No resignation of the Property Trustee shall be effective
unless either:

                   (i)     the Trust has been completely liquidated and the
          proceeds of the liquidation distributed to the Holders of Securities
          pursuant to the terms of the Securities; or

                   (ii)    a Successor Property Trustee has been appointed and
          accepted that appointment in accordance with Section 5.6.

          (g)      The Property Trustee shall have the legal power to exercise
all of the rights, powers and privileges of a holder of Subordinated Debt
Securities under the Indenture and, if an Event of Default occurs and is
continuing, the Property Trustee shall, for the benefit of Holders of the
Securities, 

                                      15
<PAGE>
 
enforce its rights as holder of the Subordinated Debt Securities subject to the
rights of the Holders pursuant to the terms of such Securities and this
Declaration.

          (h)      The Property Trustee may authorize one or more Persons (each,
a "Paying Agent") to pay Distributions, redemption payments or liquidation
payments on behalf of the Trust with respect to the Preferred Securities and any
such Paying Agent shall comply with (S) 317(b) of the Trust Indenture Act. Any
Paying Agent may be removed by the Property Trustee at any time and a successor
Paying Agent or additional Paying Agents may be appointed at any time by the
Property Trustee.

          (i)      Subject to this Section 3.8, the Property Trustee shall have
none of the powers or the authority of the Regular Trustees set forth in Section
3.6.

          (j)      The Property Trustee must exercise the powers set forth in
this Section 3.8 in a manner which is consistent with the purposes, functions
and characterization for United States federal income tax purposes of the Trust
set forth in Section 3.3 and the Property Trustee shall not take any action
which is inconsistent with or contrary to the purposes, functions and
characterization for United States federal income tax purposes of the Trust set
out in Section 3.3.

     Section 3.9.  Certain Duties and Responsibilities of the Property Trustee.
                   ----------------------------------------------------------- 

          (a)      The Property Trustee, before the occurrence of any Event of
Default and after the curing or waiver of all Events of Default that may have
occurred:

                   (i)     shall undertake to perform only such duties as are
          specifically set forth in this Declaration and in the terms of the
          Securities, and no implied covenants, duties or obligations shall be
          read into this Declaration against the Property Trustee; and

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

In case an Event of Default has occurred (that has not been cured or waived
pursuant to Section 2.6), the Property Trustee shall exercise such of the rights
and powers vested in it by this Declaration, and use the same degree of care and
skill in their exercise or use, as a prudent person would exercise or use under
the circumstances in the conduct of his or her own affairs;

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

                   (i)     this Subsection shall not be construed to limit
          Subsection (a) of this Section;

                                      16
<PAGE>
 
                   (ii)    the Property Trustee shall not be liable for any
          error of judgment made in good faith by a Responsible Officer of the
          Property Trustee, unless it shall be proved that the Property Trustee
          was negligent in ascertaining the pertinent facts;

                   (iii)   the Property Trustee shall not be liable with respect
          to any action taken or omitted to be taken by it in good faith in
          accordance with the direction of the Holders of not less than a
          Majority in liquidation amount of the Securities at the time
          outstanding 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 Declaration including, without limitation, with respect to
          the Securities; and

                   (iv)    no provision of this Declaration shall require the
          Property Trustee to expend or risk its own funds or otherwise incur
          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 ground for believing that the repayment of such funds or
          adequate indemnity against such risk or liability is not reasonably
          assured to it.

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

     Section 3.10  Certain Rights of the Property Trustee.  Subject to the

Affiliates, and may include any of its employees;

          (f)      the Property Trustee shall be under no obligation to exercise

have offered to the Property Trustee security or indemnity satisfactory to it

Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit and, if the Property Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to
examine the books, records and premises of the Trust, personally or by agent or
attorney at the expense of the Sponsor and shall incur no liability or 
additional liability of any kind by reason of such inquiry or investigation;

          (h)      any action taken by the Property Trustee or its agents
hereunder shall bind the Trust and the Holders of the Securities and the
signature of the Property Trustee or its agents alone shall be sufficient and
effective to perform any such action; and no third party shall be required to

               Common Securities (the "Successor Common Securities"), so long as
               the Successor Common Securities rank the same as the Common
               Securities rank with respect to Distributions and payments upon

                   (iii)   such merger, consolidation, amalgamation, conversion
          or replacement does not cause the Preferred Securities (including any
          Successor Securities) to be downgraded by any nationally recognized
          statistical rating organization;

                    (iv)   such merger, consolidation, amalgamation, conversion
          or replacement does not adversely affect the rights, preferences and
          privileges of the Holders of the Securities (including any Successor
          Securities and any Successor Common Securities) in any material
          respect (other than with respect to any dilution of the Holders'
          interest in the new entity);

                   (v)     such Successor Entity has a purpose substantially
          identical to that of the Trust;

                   (vi)    prior to such merger, consolidation, amalgamation,
          conversion or replacement, the Sponsor has received an opinion of
          counsel to the Trust experienced in such matters to the effect that:

                           (A)    such merger, consolidation, amalgamation,
               conversion or replacement does not adversely affect the rights,
               preferences and privileges of the Holders of the Securities
               (including any Successor Securities and Successor common
               securities) in any material respect (other than with respect to
               any dilution of the Holders' interest in the new entity);

                           (B)    following such merger, consolidation,
               amalgamation, conversion or replacement, neither the Trust nor
               the Successor Entity will be required to register as an
               Investment Company; and

                           (C)    following such merger, consolidation,
               amalgamation, conversion or replacement, the Successor Entity
               will continue to be classified as a grantor trust for United
               States federal income tax purposes; and

                   (vii)   the Sponsor guarantees the obligations of such
          Successor Entity under the Successor Securities and Successor Common
          Securities at least to the extent provided by the Preferred Securities
          Guarantee and the Common Securities Guarantee, respectively; and

          (c)      notwithstanding Section 3.15(b), the Trust shall not (except
with the written consent of Holders of 100% of the outstanding Preferred
Securities) consolidate, amalgamate, merge with or into, convert into or be
replaced by any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger, conversion or replacement would cause the Trust or
Successor Entity to be classified as other than a grantor trust for United
States federal income tax purposes. Prior to such merger, consolidation,
amalgamation, conversion or replacement, the Sponsor shall have received an
opinion of tax counsel to the Trust, experienced in such matters to the effect
that following such merger, consolidation, amalgamation, conversion or
replacement, the Trust will continue to be classified as grantor trust for
United States federal income tax purposes.

          of a Majority in liquidation amount of the Common Securities voting as
          a class at a meeting of the Holders of the Common Securities; and

             (b)

                   (i)     The Trustee that acts as Property Trustee shall not
          be removed in accordance with Section 5.6(a) until a Successor
          Property Trustee possessing the qualifications to act as Property

          appointed and has accepted such appointment by written instrument

                   (ii)    So long as a Delaware Trustee is required pursuant to
          Section 5.1, the Trustee that acts as Delaware Trustee shall not be
          removed in accordance with Section 5.6(a) until a successor Trustee
          possessing the qualifications to act as Delaware Trustee under
          Sections 5.2 and 5.4 (a "Successor Delaware Trustee") has been
          appointed and has accepted such appointment by written instrument

specified therein; provided, however, that:

                   (i)     no such resignation of the Trustee that acts as the
          Property Trustee shall be effective (A) until a Successor Property
          Trustee has been appointed and has accepted such appointment by
          instrument executed by such Successor Property Trustee and delivered
          to the Trust, the Sponsor and the resigning Property Trustee; or (B)

<PAGE>
 
                   (ii)    so long as a Delaware Trustee is required pursuant to
          Section 5.1, no such resignation of the Trustee that acts as the
          Delaware Trustee shall be effective until a Successor Delaware Trustee
          has been appointed and has accepted such appointment by instrument
          executed by such Successor Delaware Trustee and delivered to the
          Trust, the Sponsor and the resigning Delaware Trustee.

Trustee shall have been appointed and accepted appointment as provided in this

     Section 5.7.  Vacancies Among Trustees.  If a Trustee ceases to hold office
                   ------------------------

accordance with Section 5.6.

     Section 5.8.  Effect of Vacancies.  The death, resignation, retirement,
                   ------------------- 
removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to
perform the duties of a Trustee, or any one of them, shall not operate to
dissolve, terminate or annul the Trust. Whenever a vacancy in the number of
Regular Trustees shall occur, until such vacancy is filled by the appointment of
a Regular Trustee in accordance with Section 5.6, the Regular Trustees in
office, regardless of their number, shall have all the powers granted to the
Regular Trustees and shall discharge all the duties imposed upon the Regular
Trustees by this Declaration.

meeting. Notice of any telephonic meetings of the Regular Trustees or any
committee thereof shall be hand delivered or otherwise delivered in writing
(including by facsimile, with a hard copy by overnight courier) not less than 24
hours before a meeting. Notices shall contain a brief statement of the time,
place and anticipated purposes of the meeting. The presence (whether in person
or by telephone) of a Regular Trustee at a meeting shall constitute a waiver of
notice of such meeting except where a Regular Trustee attends a meeting for the
express purpose of objecting to the transaction of any activity on the ground
that the meeting has not been lawfully called or convened. Unless provided
otherwise in this Declaration, any action of the Regular Trustees may be taken
at a meeting by vote of a majority of the Regular Trustees present (whether in
person or by telephone) and eligible to vote with respect to such matter,
provided that a Quorum is present, or without a meeting by the unanimous written
consent of the Regular Trustees.

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 3.6
including any registration statement or amendment thereto filed with the
Commission or making any other governmental filing.

            (b)    The Regular Trustees shall have power to delegate from time
to time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Regular Trustees or otherwise as the Regular Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of the Trust, as set forth herein.

     Section 5.11. Merger, Conversion, Consolidation or Succession to Business.
                    ----------------------------------------------------------- 
Any corporation into which the Property Trustee or the Delaware Trustee, as the
case may be, may be merged or converted or with which either may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Property Trustee or the Delaware Trustee, as the case
may be, shall be bound by this Declaration, or any corporation succeeding to all
or substantially all the corporate trust business of the Property Trustee or the
Delaware Trustee, as the case may be, shall be the successor of the Property
Trustee or the Delaware Trustee, as the case may be, hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.


                                  ARTICLE VI.

                                 DISTRIBUTIONS

     Section 6.1.  Distributions.  Holders shall receive Distributions in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in their respective
terms. If and to the extent that the Subordinated Debt Securities Issuer makes a
payment of interest (including Additional Interest (as defined in the
Indenture)), premium, if any, and principal on the Subordinated Debt Securities
held by the Property Trustee (the amount of any such payment being a "Payment
Amount"), the Property Trustee shall and is directed, to the extent funds are
available for that purpose, to make a distribution (a "Distribution") of the
Payment Amount to Holders. In the event the Sponsor shall defer any payment of
principal, premium, if any, or interest on the Subordinated Debt Securities, the
Trust shall, in like manner, defer payments of Distributions on the Securities,
and Additional Distributions shall accrue on such Securities for so long as the
payment of principal, premium, if any, or interest on the Subordinated Debt
Securities is deferred.


                                 ARTICLE VII.

                            ISSUANCE OF SECURITIES

     Section 7.1.  General Provisions Regarding Securities.
                   --------------------------------------- 

            (a)    The Regular Trustees shall, on behalf of the Trust, issue one
class of preferred securities representing undivided beneficial interests in the
assets of the Trust having such terms as are set forth in Exhibit A and
incorporated herein by reference (the "Preferred Securities"), and one class of


                                      26
<PAGE>
 
common securities representing undivided beneficial interests in the assets of
the Trust having such terms as are set forth in Exhibit A and incorporated
herein by reference (the "Common Securities").  The Trust shall have no
securities or other interests in the assets of the Trust other than the
Preferred Securities and the Common Securities;

          (b)  the Certificates shall be signed on behalf of the Trust by the
Regular Trustees (or if there are more than two Regular Trustees by any two of
the Regular Trustees).  Such signatures may be the manual or facsimile
signatures of the present or any future Regular Trustee.  Typographical and
other minor errors or defects in any such reproduction of any such signature
shall not affect the validity of any Certificate.  In case any Regular Trustee
of the Trust who shall have signed any of the Certificates shall cease to be
such Regular Trustee before the Certificate so signed shall be delivered by the
Trust, such Certificate nevertheless may be delivered as though the person who
signed such Certificate had not ceased to be such Regular Trustee; and any
Certificate may be signed on behalf of the Trust by such persons who shall at
the actual date of execution of such Security, be the Regular Trustees of the
Trust, although at the date of the execution and delivery of the Declaration any
such person was not such a Regular Trustee.  Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation of
any stock exchange on which Securities may be listed, or to conform to usage.  A
Preferred Security shall not be valid until authenticated by the manual
signature of an authorized signatory of the Property Trustee.  The signature
shall be conclusive evidence that the Preferred Security has been authenticated
under this Declaration.  Upon a written order of the Trust signed by one Regular
Trustee, the Property Trustee shall authenticate the Preferred Securities for
original issue.  The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Preferred Securities.  An authenticating
agent may authenticate Preferred Securities whenever the Property Trustee may do
so.  Each reference in this Declaration to authentication by the Property
Trustee includes authentication by such agent.  An authenticating agent has the
same rights as the Property Trustee to deal with the Trust or an Affiliate;

          (c)  the consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust;

          (d)  upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be deemed to be validly issued, fully paid and
nonassessable; and

          (e)  every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by this Declaration.

          Common Securities;

               (ii)  upon the filing of a certificate of dissolution or its

          of this Section 8.1(a)) of the Holders of at least a Majority in
          liquidation amount of the Securities, voting together as a single
          class, and the consent of the Sponsor, to dissolve the Trust, or the
          revocation of the articles of incorporation of the Sponsor or the
          Holder of the Common Securities and the expiration of 90 days after
          the date of revocation without a reinstatement thereof;

               (iii) upon the entry of a decree of judicial dissolution of the
          Sponsor or the Trust or the Holder of the Common Securities;
                
               (iv)  when all of the Securities shall have been called for
          redemption and the amounts necessary for redemption thereof shall have
          been paid to the Holders in accordance with the terms of the
          Securities;
       
               (v)  upon the written direction to the Property Trustee from the
          Sponsor at any time to dissolve the Trust and, after satisfaction of
          liabilities to creditors of the Trust as provided by applicable law,
          the distribution of Subordinated Debt Securities to Holders in
          exchange for the Securities, subject to the Regular Trustees' receipt
          of an opinion of counsel experienced in such matters to the effect
          that the Holders of the Preferred Securities will not recognize any
          income, gain or loss for United States federal income tax purposes as
          a result of the dissolution of the Trust and such distribution to
          Holders; or

               (vi)  before the issuance of any Securities, with the consent of
          all  of the Regular Trustees and the Sponsor.

          (b)  As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a) or dissolution pursuant to Section 3.14 and upon
the completion of the winding up of the Trust, one of the Regular Trustees (each
Regular Trustee being hereby authorized to take such action) shall file a
certificate of cancellation with the Secretary of State of the State of Delaware
terminating the Trust.

          (c)  The provisions of Section 3.9 and Article X shall survive the
termination of the Trust.

                                  ARTICLE IX.

                             TRANSFER OF INTERESTS

     Section 9.1.  Transfer of Securities.
                   ---------------------- 

          (a)  Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Declaration and in
the terms of the Securities.  Any transfer or purported transfer of any Security
not made in accordance with this Declaration shall be null and void;

          (b)  subject to this Article IX, Preferred Securities shall be freely
transferable; and

          (c)  subject to this Article IX, the Sponsor and any Related Party may
only transfer Common Securities to the Sponsor or a Related Party of the
Sponsor, or as contemplated by Article VIII of the Indenture; provided that, any
such transfer shall not violate the Securities Act and is subject to the

                                      28
<PAGE>
 
condition precedent that the transferor obtain the written opinion of counsel
experienced in such matters that such transfer would not cause more than an
insubstantial risk that:

               (i)   the Trust would not be classified for United States federal
          income tax purposes as a grantor trust; and

               (ii)  the Trust would be an Investment Company required to
          register under the Investment Company Act or the transferee would
          become an Investment Company required to register under the Investment
          Company Act.

          (d)  Each Common Security that bears or is required to bear the legend
set forth in this Section 9.1(d) shall be subject to the restrictions on
transfer provided in the legend set forth in this Section 9.1(d), unless such
restrictions on transfer shall be waived by the written consent of the Regular
Trustees, and the Holder of each such Common Security, by such security holder's
acceptance thereof, agrees to be bound by such restrictions on transfer.  As
used in this Section 9.1(d) and in Section 9.1(c), the term "transfer"
encompasses any sale, pledge, transfer or other disposition of any such Common
Security.

     Any certificate evidencing a Common Security shall bear a legend in
substantially the following form, unless otherwise agreed by the Regular
Trustees (with written notice thereof to the Property Trustee):

     THE SECURITY EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
     SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
     ACCORDINGLY, MAY NOT BE OFFERED OR SOLD UNLESS SUCH OFFER AND SALE ARE
     REGISTERED UNDER OR ARE EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT.
     THE TRANSFER OF THE SECURITY EVIDENCED HEREBY IS ALSO SUBJECT TO THE
     RESTRICTIONS SET FORTH IN THE DECLARATION REFERRED TO BELOW.

     Section 9.2.  Transfer of Certificates.
                   ------------------------ 

          (a)  The Regular Trustees shall provide for the registration of
Certificates and of transfers of Certificates, which will be effected without
charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges which may be imposed
in relation to it.  Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to be
issued in the name of the designated transferee or transferees.  Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees duly
executed by the Holder or such Holder's attorney duly authorized in writing.
Each Certificate surrendered for registration of transfer shall be canceled by
the Regular Trustees.  A transferee of a Certificate shall be entitled to the
rights and subject to the obligations of a Holder hereunder upon the receipt by
such transferee of a Certificate.  By acceptance of a Certificate, each
transferee shall be deemed to have agreed to be bound by this Declaration and
the documents incorporated by reference herein.

          (b)  Notwithstanding any other provisions of this Declaration, a
Global Certificate may not be transferred as a whole, except by the Clearing
Agency to a nominee of the Clearing Agency or by the Clearing Agency or any such
nominee to a successor Clearing Agency or a nominee of such successor Clearing
Agency.

     Section 9.3.  Deemed Security Holders.  The Trustees may treat the Person
                   -----------------------
in whose name any Certificate shall be registered on the books and records of
the Trust as the sole holder of such Certificate and of the Securities
represented by such Certificate for purposes of receiving Distributions and for
all other purposes whatsoever and, accordingly, shall not be bound to recognize
any equitable or other claim to or interest in such Certificate or in the
Securities represented by such Certificate on the part of any Person, whether or
not the Trustees shall have actual or other notice thereof.

     Section 9.4.  Book Entry Interests.
                   -------------------- 

          (a)  So long as Preferred Securities are eligible for book entry
settlement with the Clearing Agency or unless otherwise required by law, all
Preferred Securities that are so eligible may be represented by one or more,
fully registered, global Preferred Security Certificates (each a "Global
Certificate"), to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Trust.  Such Global Certificates shall initially be registered on
the books and records of the Trust in the name of Cede & Co., the nominee of
DTC, and no Preferred Security Beneficial Owner will receive a definitive
Preferred Security Certificate representing such Preferred Security Beneficial
Owner's interests in such Global Certificates, except as provided in Section
9.7.  The transfer and exchange of beneficial interests in any such Security in
global form shall be effected through the Clearing Agency in accordance with
this Declaration and the procedures of the Clearing Agency therefor.

          (b)  Except as provided below, Beneficial Owners of a Preferred
Security in global form shall not be entitled to have certificates registered in
their names, will not receive or be entitled to receive physical delivery of
certificates in definitive form and will not be considered Holder of such
Preferred Security in global form.

          (c)  Any Global Certificate may be endorsed with or have incorporated
in the text thereof such legends or recitals or changes not inconsistent with
the provisions of this Declaration as may be required by the Clearing Agency, by
any national securities exchange or by the National Association of Securities
Dealers, Inc. as may be required to comply with any applicable law or any
regulation thereunder or with the rules and regulations of any securities
exchange or interdealer quotation system upon which the Preferred Securities may
be listed or traded or to conform with any usage with respect thereto, or to
indicate any special limitations or restrictions to which any particular
Preferred Securities are subject.

          (d)  Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") have been issued
to the Preferred Security Beneficial Owners pursuant to Section 9.7:

               (i)   the provisions of this Section 9.4 shall be in full force
          and effect with respect to such Preferred Securities;

               (ii)  the Trust and the Trustees shall be entitled to deal with
          the Clearing Agency for all purposes of this Declaration (including
          the payment of Distributions on the Global Certificates and receiving
          approvals, votes or consents hereunder) as the Holder of the Preferred
          Securities and the sole holder of the Global Certificates and shall
          have no obligation to the Preferred Security Beneficial Owners;

               (iii) to the extent that the provisions of this Section 9.4
          conflict with any other provisions of this Declaration, the provisions
          of this Section 9.4 shall control; and

                                      30
<PAGE>
 
               (iv)  the rights of the Beneficial Owners of Preferred Securities
          in global form shall be exercised only through the Clearing Agency and
          shall be limited to those established by law and agreements between
          such Preferred Security Beneficial Owners and the Clearing Agency
          and/or the Clearing Agency Participants.  The Clearing Agency will
          make book entry transfers among the Clearing Agency Participants and
          receive and transmit payments of Distributions on the Global
          Certificates to such Clearing Agency Participants.  DTC will make book
          entry transfers among the Clearing Agency Participants, provided, that
          solely for the purposes of determining whether the Holders of the
          requisite amount of Preferred Securities have voted on any matter
          provided for in this Declaration, so long as Definitive Preferred
          Security Certificates have not been issued, the Trustees may
          conclusively rely on, and shall be protected in relying on, any
          written instrument (including a proxy) delivered to the Trustees by
          the Clearing Agency setting forth the Preferred Securities Beneficial
          Owners' votes or assigning the right to vote on any matter to any
          other Persons either in whole or in part.

     Notwithstanding any other provisions of this Declaration (other than the
provisions set forth in this Section 9.4(c)), a Preferred Security in global
form may not be transferred as a whole except by the Clearing Agency to a
nominee of the Clearing Agency or by a nominee of the Clearing Agency to the
Clearing Agency or another nominee to a successor Clearing Agency or a nominee
of such successor Clearing Agency.

     Section 9.5.  Notices to Clearing Agency.  Whenever a notice or other
                   --------------------------
communication to the Preferred Security Holders is required under this
Declaration, unless and until Definitive Preferred Security Certificates shall
have been issued to the Preferred Security Beneficial Owners pursuant to Section
9.7, the Trustees shall give all such notices and communications, specified
herein to be given to the Preferred Security Holders, to the Clearing Agency,
and shall have no notice obligations to the Preferred Security Beneficial
Owners.

     Section 9.6.  Appointment of Successor Clearing Agency.  If any Clearing
                   ----------------------------------------
Agency notifies the Trust that it is unwilling or unable to continue its
services as securities depositary with respect to the Preferred Securities if
such Clearing Agency ceases to perform such services, or if at any time such
Clearing Agency ceases to be a clearing agency registered as such under the
Exchange Act when such Clearing Agency is required to be so registered to act as
such depositary, then the Regular Trustees may, in their sole discretion,
appoint a successor Clearing Agency with respect to such Preferred Securities.

     Section 9.7.  Definitive Preferred Security Certificates Under Certain
                   --------------------------------------------------------
Circumstances.  If:
- ------------- 

          (a)  a Clearing Agency notifies the Trust that it is unwilling or
unable to continue its services as securities depositary with respect to the
Preferred Securities, if such Clearing Agency ceases to perform such services,
or if at any time such Clearing Agency ceases to be a clearing agency registered
as such under the Exchange Act when such Clearing Agency is required to be so
registered to act as such depositary, and a successor Clearing Agency is not
appointed within 90 days after such discontinuance pursuant to Section 9.6; or

          (b)  the Regular Trustees (with the consent of the Sponsor) in their
sole discretion determine that the Preferred Securities in global form shall be
exchanged for certificated Preferred Securities;

                                      31
<PAGE>
 
     then:

               (i)   Definitive Preferred Security Certificates shall be
          prepared by the Regular Trustees on behalf of the Trust with respect
          to such Preferred Securities; and

               (ii)  upon surrender of the Global Certificates by the Clearing
          Agency, accompanied by registration instructions, the Regular Trustees
          shall cause Definitive Preferred Security Certificates to be delivered
          to Preferred Security Beneficial Owners of such Preferred Securities
          in accordance with the instructions of the Clearing Agency.  Neither
          the Trustees nor the Trust shall be liable for any delay in delivery
          of such instructions and each of them may conclusively rely on and
          shall be protected in relying on, said instructions of the Clearing
          Agency.  The Definitive Preferred Security Certificates shall be
          printed, lithographed or engraved or may be produced in any other
          manner as is reasonably acceptable to the Regular Trustees, as
          evidenced by their execution thereof, and may have such letters,
          numbers or other marks of identification or designation and such
          legends or endorsements as the Regular Trustees may deem appropriate,
          or as may be required to comply with any law or with any rule or
          regulation made pursuant thereto or with any rule or regulation of any
          stock exchange on which Preferred Securities may be listed, or to
          conform to usage.

     At such time as all interests in a Preferred Security in global form have
been redeemed, exchanged, repurchased or canceled, such Preferred Security in
global form shall be, upon receipt thereof, canceled by the Trust in accordance
with standing procedures and instructions of the Clearing Agency.

     Section 9.8.  Mutilated, Destroyed, Lost or Stolen Certificates  If:
                   -------------------------------------------------

          (a)  any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and

          (b)  there shall be delivered to the Property Trustee or the Regular
Trustees such security or indemnity as may be required by them to keep each of
them harmless,

          then:

in the absence of notice that such Certificate shall have been acquired by a
bona fide purchaser, the Property Trustee or any Regular Trustee on behalf of
the Trust shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.8, the Property Trustee or the Regular Trustees 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 Certificate issued
pursuant to this Section shall constitute conclusive evidence of an ownership
interest in the relevant Securities, as if originally issued, whether or not the
lost, stolen or destroyed Certificate shall be found at any time.

          (a)  Except as expressly set forth in this Declaration, the Preferred
Securities Guarantee, the Common Securities Guarantee and the terms of the
Securities, the Sponsor shall not be:

               (i)   personally liable for the return of any portion of the
          capital contributions (or any return thereon) of the Holders of the
          Securities, which shall be made solely from assets of the Trust; or

               (ii)  required to pay to the Trust or to any Holder of Securities
          any deficit upon dissolution of the Trust or otherwise.

          (b)  Pursuant to (S) 3803(a) of the Business Trust Act, the Holders of
the Securities, in their capacity as such, shall be entitled to the same

     Section 10.2.  Exculpation.
                    ----------- 

          (a)  No Indemnified Person shall be liable, responsible or accountable
in damages or otherwise to the Trust or any Covered Person for any loss, damage
or claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Declaration or by law, except that
an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's negligence (or, in the case of
the Property Trustee, except as otherwise set forth in Section 3.9) or willful
misconduct with respect to such acts or omissions.

          (b)  An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Trust and upon such information, opinions, reports
or statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses, or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

     Section 10.3.  Fiduciary Duty.
                    -------------- 

          (a)  To the extent that, at law or in equity, an Indemnified Person
has duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any other Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any other Covered Person for
its good faith reliance on the provisions of this Declaration.  The provisions
of this Declaration, to the extent that they restrict the duties and liabilities
of an Indemnified Person otherwise existing at law or in equity (other than
duties imposed on the Property Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person;

          Indemnified Person and any Covered Persons; or

               (ii)   whenever this Declaration or any other agreement
          contemplated herein or therein provide that an Indemnified Person
          shall act in a manner that is, or provides terms that are, fair and
          reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

          (c)  Whenever in this Declaration an Indemnified Person is permitted
or required to make a decision:

          the Indemnified Person shall be entitled to consider such interests
          and factors as it desires, including its own interests, and shall have
          no duty or obligation to give any consideration to any interest of or
          factors affecting the Trust or any other Person; or

               (ii)   in its "good faith" or under another express standard, the
          Indemnified Person shall act under such express standard and shall not
          be subject to any other or different standard imposed by this
          Declaration or by applicable law.

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

          (a)  To the fullest extent permitted by law, the Sponsor shall
fully indemnify each Indemnified Person for, and hold each Indemnified Person
harmless against, any and all loss, liability, expense, damage or claim incurred

by such Indemnified Person without negligence or bad faith on behalf of the
Trust and in a manner such Indemnified Person reasonably believed to be within
the scope of authority conferred on such Indemnified Person by this Declaration;

          (b)  reasonable expenses (including reasonable legal fees and
expenses) incurred by an Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by the Sponsor
prior to the final disposition of such claim, demand, action, suit or proceeding
upon receipt by the Sponsor of an undertaking by or on behalf of the Indemnified
Person to repay such amount if it shall be determined that the Indemnified
Person is not entitled to be indemnified as authorized in Section 10.4(a); and

          (c)  the provisions of this Section 10.4 shall survive the termination

description, independently or with others, similar or dissimilar to the business
of the Trust, and the Trust and the Holders of Securities shall have no rights
by virtue of this Declaration in and to such independent ventures or the income
or profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Trust, shall not be deemed wrongful or
improper. No Covered Person, the Sponsor, the Delaware Trustee, or the Property
Trustee shall be obligated to present any particular investment or other
opportunity to the Trust even if such opportunity is of a character that, if
presented to the Trust, could be taken by the Trust, and any Covered Person, the
Sponsor, the Delaware Trustee and the Property Trustee shall have the right to
take for its own account (individually or as a partner or fiduciary) or to
recommend to others any such particular investment or other opportunity. Any
Covered Person, the Delaware Trustee and the Property Trustee may engage or be
interested in any financial or other transaction with the Sponsor or any
Affiliate of the Sponsor, or may act as depositary for, trustee or agent for, or
act on any committee or body of holders of, securities or other obligations of
the Sponsor or its Affiliates.

     Section 11.1  Fiscal Year.  The fiscal year ("Fiscal Year") of the Trust
                   -----------
shall be the calendar year, or such other year as is required by the Code.

     Section 11.2. Certain Accounting Matters.
                   -------------------------- 

          (a)  At all times during the existence of the Trust, the Trust shall
keep, or cause to be kept, full books of account, records and supporting
documents, which shall reflect in reasonable detail, each transaction of the
Trust.  The books of account shall be maintained on the accrual method of
accounting, in accordance with generally accepted accounting principles,
consistently applied.  The Trust shall use the accrual method of accounting for
United States federal income tax purposes.  The books of account and the records
of the Trust shall be examined by and reported upon, as of the end of each
Fiscal Year, by a firm of independent certified public accountants selected by
the Regular Trustees of the Trust.

          (b)  The Trust shall cause to be duly prepared and delivered to each
of the Holders of Securities, any annual United States federal income tax
information statement, required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations.  Notwithstanding any right under the Code to deliver any
such statement at a later date, the Trust shall endeavor to deliver all such
statements within 30 days after the end of each Fiscal Year of the Trust.

          (c)  The Trust shall cause to be duly prepared and filed with the
appropriate taxing authority, an annual United States federal income tax return,
on a Form 1041 or such other form required by United States federal income tax
law, and any other annual income tax returns required to be filed by the Trust
on behalf of the Trust with any state or local taxing authority.

     Section 11.3.  Banking.  The Trust shall maintain one or more bank accounts
                    -------
in the name and for the sole benefit of the Trust; provided, however, that all
payments of funds in respect of the Subordinated Debt Securities held by the
Property Trustee shall be made directly to the Property Trustee Account

                                      35
<PAGE>
 
and no other funds of the Trust shall be deposited in the Property Trustee
Account. The sole signatories for such accounts shall be designated by the
Regular Trustees; provided, however, that the Property Trustee shall designate
the signatories for the Property Trustee Account.

     Section 11.4   Withholding.  The Trust shall comply with all withholding
                    -----------
requirements under United States federal, state and local law. The Trust shall
request, and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations. The Trust shall file required forms with applicable
jurisdictions and, unless an exemption from withholding is properly established
by a Holder, shall remit amounts withheld with respect to the Holder to
applicable jurisdictions. To the extent that the Trust is required to withhold
and pay over any amounts to any authority with respect to distributions or
allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of any
claimed over-withholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount required to be withheld was not withheld
from actual Distributions made, the Trust may reduce subsequent Distributions by
the amount of such withholding.

                                  ARTICLE XII.

there are more than two (2) Regular Trustees, a majority of the Regular
Trustees); provided, however, that:

               (i)   no amendment shall be made, and any such purported

                    (A) cause the Trust to fail to be classified for the
               purposes of United States federal income taxation as a grantor
               trust;

                    (B) affect the powers or the rights of the Property Trustee
               or the Delaware Trustee without the written consent of the
               Property Trustee or the Delaware Trustee, as the case may be; or

                    (C) cause the Trust to be deemed to be an Investment Company
               which is required to be registered under the Investment Company
               Act;

               (ii)  at such time after the Trust has issued any Securities
          which remain outstanding, any amendment which would adversely affect
          the rights, privileges or preferences of any Holder of Securities may
          be effected only with such additional requirements as may be set forth
          in the terms of such Securities;

               (iii) Section 9.1 (c) and this Section 12.1 shall not be amended
          without the consent of all of the Holders of the Securities;

<PAGE>
 
               (iv)  Article IV shall not be amended without the consent of the
          Holders of a Majority in liquidation amount of the Common Securities;
          and

               (v)  the rights of the Holders of the Common Securities under
          Article V to increase or decrease the number of, and appoint and
          remove Trustees shall not be amended without the consent of the
          Holders of a Majority in liquidation amount of the Common Securities.

          (b)  Notwithstanding Section 12.1(a)(ii), this Declaration may be
amended from time to time by the Holders of a Majority in liquidation amount of
the Common Securities and the Property Trustee, without the consent of the
Holders of the Preferred Securities, to:

               (i)   cure any ambiguity;

               (ii)  correct or supplement any provision in this Declaration
          that may be defective or inconsistent with any other provision or to
          make any other provisions with respect to matters or questions arising
          under this Declaration, which shall not be inconsistent with the other
          provisions of this Declaration;

               (iii) add to the covenants, restrictions or obligations of the
          Sponsor;

               (iv)  to ensure the Trust's classification as a grantor trust for
          United States federal income tax purposes; and

               (v)   to modify, eliminate or add to any provisions of this
          Declaration to such extent as shall be necessary to ensure that the
          Trust will not be required to register as an investment company under
          the Investment Company Act.

          (c)  Subject to Section 12.1(a), this Declaration may be amended by
the Holders of a Majority in liquidation amount of the Common Securities and the
Property Trustee if:

               (i)  the Holders of a Majority in liquidation amount of the
          Preferred Securities consent to such amendment; and

               (ii)  the Regular Trustees have received an opinion of counsel
          experienced in such matters to the effect that such amendment or the
          exercise of any power granted to the Regular 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 the Trust's
          exemption from status as an "investment company" under the Investment
          Company Act.

          (d)  Any amendments of this Declaration pursuant to Section 12.1(b)
shall become effective when notice thereof is given to Holders of Securities.
Any other amendments of this Declaration shall become immediately effective, 
however, within ten (10) days of such effective date notice must be given to 
Holders of Securities, which notice may be given by press release or other 
similar widely disseminated means.

     Section 12.2.  Meetings of the Holders of Securities; Action by Written
                    --------------------------------------------------------
Consent.
- ------- 

          (a)  Meetings of the Holders of any class of Securities may be called
at any time by the Regular Trustees (or as provided in the terms of the
Securities) to consider and act on any matter on which Holders of such class of
Securities are entitled to act under the terms of this Declaration, the terms of
the Securities or the rules of any stock exchange on which the Preferred
Securities are listed or admitted for trading.  The Regular Trustees shall call
a meeting of the Holders of such class of Holders,

                                      37
<PAGE>
 
if directed to do so by the Holders of at least 25% in liquidation amount of the
Securities of such class. Such direction shall be given by delivering to the
Regular Trustees one or more calls in a writing stating that the signing Holders
of Securities wish to call a meeting and indicating the general or specific
purpose for which the meeting is to be called. Any Holders of Securities calling
a meeting shall specify in writing the Security Certificates held by the Holders
of Securities exercising the right to call a meeting and only those Securities
specified shall be counted for purposes of determining whether the required
percentage set forth in the second sentence of this paragraph has been met.

          (b)  Except to the extent otherwise provided in the terms of the
Securities, the following provisions shall apply to meetings of Holders of
Securities:

               (i)   notice of any such meeting shall be given to all the
          Holders of Securities having a right to vote thereat at least seven
          (7) days and not more than 60 days before the date of such meeting.
          Whenever a vote, consent or approval of the Holders of Securities is
          permitted or required under this Declaration, the terms of the
          Securities or the rules of any stock exchange on which the Preferred
          Securities are listed or admitted for trading, such vote, consent or
          approval may be given at a meeting of the Holders of Securities. Any
          action that may be taken at a meeting of the Holders of Securities may
          be taken without a meeting and without prior notice if a consent in
          writing setting forth the action so taken is signed by the Holders of
          Securities owning not less than the minimum amount of Securities in
          liquidation amount that would be necessary to authorize or take such
          action at a meeting at which all Holders of Securities having a right
          to vote thereon were present and voting. Prompt notice of the taking
          of action without a meeting shall be given to the Holders of
          Securities entitled to vote who have not consented in writing. The
          Regular Trustees may specify that any written ballot submitted to the
          Security Holder for the purpose of taking any action without a meeting
          shall be returned to the Trust within the time specified by the
          Regular Trustees;

               (ii)  each Holder of a Security may authorize any Person to act
          for it by proxy on all matters in which a Holder of Securities is
          entitled to participate, including waiving notice of any meeting, or
          voting or participating at a meeting.  No proxy shall be valid after
          the expiration of 11 months from the date thereof unless otherwise
          provided in the proxy.  Every proxy shall be revocable at the pleasure
          of the Holder of Securities executing it.  Except as otherwise
          provided herein, all matters relating to the giving, voting or
          validity of proxies shall be governed by the General Corporation Law
          of the State of Delaware relating to proxies, and judicial
          interpretations thereunder, as if the Trust were a Delaware
          corporation and the Holders of the Securities were stockholders of a
          Delaware corporation;

               (iii) each meeting of the Holders of the Securities shall be
          conducted by the Regular Trustees or by such other Person that the
          Regular Trustees may designate; and

               (iv)  except to the extent that the Business Trust Act, the Trust
          Indenture Act, this Declaration, the terms of the Securities or the
          listing rules of any stock exchange on which the Preferred Securities
          are then listed or trading otherwise provides, the Regular Trustees,
          in their sole discretion, shall establish all other provisions
          relating to meetings of Holders of Securities, including notice of the
          time, place or purpose of any meeting at which any matter is to be
          voted on by any Holders of Securities, waiver of any such notice,
          action by consent without a meeting, the establishment of a record
          date, quorum

                                      38

          requirements, voting in person or by proxy or any other matter with
          respect to the exercise of any such right to vote.

     Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust,
dated as of [ ], [1999]/[200_] (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Preferred Securities and the Common
Securities are set out below (each capitalized term used but not defined herein
has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus referred to below):

     1.     Designation and Number.
            ---------------------- 

            a.  Preferred Securities.  [ ] Preferred Securities [(including [ ]
                --------------------

provided for in the Purchase Agreement)] of the Trust with an aggregate
liquidation amount with respect to the assets of the Trust of [ ] Dollars ($[ ])
[(plus up to an additional [ ] Preferred Securities with an aggregate
liquidation amount with the respect to the assets of the Trust of [ ] Dollars
($[ ]) solely to cover overallotments, as provided for in the Purchase Agreement
(the "Additional Preferred Securities")),] and a liquidation amount with respect
to the assets of the Trust of $[ ] per Preferred Security, are hereby designated
for the purposes of identification only as "[ ]% Preferred Securities" (the
"Preferred Securities").  The Preferred Security Certificates evidencing the
Preferred Securities shall be substantially in the form attached hereto as Annex
I, with such changes and additions thereto or deletions therefrom as may be
required by ordinary usage, custom or practice or to conform to the rules of any
stock exchange on which the Preferred Securities are listed.

            b.  Common Securities.  [ ] Common Securities [(including [ ] Common
                -----------------                                               
Securities of the Trust sold pursuant to an overallotment option)] of the Trust
with an aggregate liquidation amount with respect to the assets of the Trust of
[ ] Dollars ($[ ]) [(plus up to an additional [ ] Common Securities of the Trust
with an aggregate liquidation amount with respect to the assets of the Trust of
[ ] Dollars ($[ ])] to meet capital requirements of the Trust in the event of an
issuance of Additional Preferred Securities), and a liquidation amount with

(the "Common Securities").  The Common Security Certificates evidencing the
Common Securities shall be substantially in the form attached hereto as Annex
II, with such changes and additions thereto or deletions therefrom as may be
required by ordinary usage, custom or practice.

     2.     Distributions.
            ------------- 

            a.  Periodic Distributions payable on each Security will be fixed at
a rate per annum of [ ]% (the "Coupon Rate") of the stated liquidation amount of
$[ ] per Security, such rate being the rate of interest payable on the
Subordinated Debt Securities to be held by the Property Trustee. Distributions
in arrears for more than one quarterly period will bear interest thereon at the
Coupon Rate (to the extent permitted by applicable law). The term
"Distributions" as used in these terms includes such periodic cash distributions
and any such interest payable unless otherwise stated. A Distribution is payable
only to the extent that payments are made in respect of the Subordinated Debt
Securities held by the Property Trustee. The amount of Distributions payable for
any period will be computed for any full quarterly Distribution period on the
basis of a 360-day year of twelve 30-day months, and for any period shorter
                                      A-1
<PAGE>
 
than a full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days elapsed
in such a 30-day month.

          b.  Distributions on the Securities will be cumulative, will accrue
from [ ], [1999]/[200_] and will be payable quarterly in arrears, on [ ], [ ], [
] and [ ] of each year, commencing on [ ], [1999]/[200_], except as otherwise
described below.  The Debenture Issuer has the right under the Indenture to
defer payments of interest by extending the interest payment period from time to
time on the Subordinated Debt Securities for a period not exceeding 20
consecutive quarterly periods (each, an "Extension Period") but not beyond the
maturity date of the Subordinated Debt Securities and, as a consequence of such
extension, Distributions will also be deferred.  Despite such deferral,
quarterly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the Coupon Rate during any such Extension
Period.  Prior to the termination of any such Extension Period, the Subordinated
Debt Securities Issuer may further extend such Extension Period; provided that
such Extension Period together with all such previous and further extensions
thereof may not exceed 20 consecutive quarterly periods.  Payments of accrued
Distributions will be payable to Holders as they appear on the books and records
of the Trust on the first record date after the end of the Extension Period.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Subordinated Debt Securities Issuer may commence a new Extension
Period, subject to the above requirements.

          c.  Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the relevant
record dates.  While the Preferred Securities remain in book entry only form,
the relevant record dates shall be one Business Day prior to the relevant
payment dates which payment dates correspond to the interest payment dates on
the Subordinated Debt Securities.  Subject to any applicable laws and
regulations and the provisions of the Declaration, each such payment in respect
of the Preferred Securities will be made as described under the heading
["Certain Terms of the Preferred Securities -- Book Entry-Only Issuance -- The
Depository Trust Company"] in the Prospectus Supplement dated [ ], [1999]/[200_]
(the "Prospectus Supplement") to the Prospectus dated [ ], [1999]/[200_] (as so
supplemented the "Prospectus") of the Trust included in the Registration
Statement on Form S-3 of the Sponsor, the Trust and certain other business
trusts.  The relevant record dates for the Common Securities shall be the same
record dates as for the Preferred Securities.  If the Preferred Securities shall
not continue to remain in book entry only form, the relevant record dates for
the Preferred Securities, shall conform to the rules of any securities exchange
on which the securities are listed and, if none, shall be selected by the
Regular Trustees, which dates shall be at least one Business Day but less than
60 Business Days before the relevant payment dates, which payment dates
correspond to the interest payment dates on the Subordinated Debt Securities.
Distributions payable on any Securities that are not punctually paid on any
Distribution payment date, as a result of the Subordinated Debt Securities
Issuer having failed to make a payment under the Subordinated Debt Securities,
will cease to be payable to the Person in whose name such Securities are
registered on the relevant record date, and such defaulted Distribution will
instead be payable to the Person in whose name such Securities are registered on
the special record date or other specified date determined in accordance with
the Indenture.  If any date on which Distributions are payable on the Securities
is not a Business Day, then payment of the Distribution payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day 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 such date.


                                      A-2
<PAGE>
 
          d.  In the event that there is any money or other property held by or
for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

     3.   Liquidation Distribution Upon Dissolution.
          ----------------------------------------- 

     In the event of any voluntary or involuntary dissolution of the Trust, the
Holders of the Securities on the date of the dissolution will be entitled to
receive out of the assets of the Trust available for distribution to Holders of
Securities, after paying or making reasonable provision to pay all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act, an amount equal to the aggregate of the stated liquidation amount of
$[ ] per Security plus accrued and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"), unless, in
connection with such dissolution, Subordinated Debt Securities in an aggregate
principal amount equal to the aggregate stated liquidation amount of such
Securities, with an interest rate equal to the Coupon Rate of, and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on, such Securities, shall be distributed on a Pro Rata basis to
the Holders of the Securities in exchange for such Securities, after paying or
making reasonable provision to pay all claims and obligations of the Trust in
accordance with Section 3808(e) of the Business Trust Act.

     If, upon any such dissolution, 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 the amounts payable directly by the
Trust on the Securities shall be paid on a Pro Rata basis.

     4.   Redemption and Distribution.
          --------------------------- 

          a.  Upon the repayment of the Subordinated Debt Securities in whole or
in part, whether at maturity or upon redemption, the proceeds from such
repayment or payment shall be simultaneously applied to redeem Securities having
an aggregate liquidation amount equal to the aggregate principal amount of the
Subordinated Debt Securities so repaid or redeemed, at the redemption price for
the Subordinated Debt Securities, payable in cash (the "Redemption Price").
Holders will be given not less than 30 nor more than 60 days notice of such
redemption.

          b.  If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Paragraph 4(h)(ii) below.

          c.  The Subordinated Debt Securities are redeemable, in whole or in
part, at the option of the Subordinated Debt Securities Issuer, on or after [ ],
[1999]/[200_], at a redemption price equal to [100%] of the principal amount per
Subordinated Debt Securities, plus, in each case, accrued and unpaid interest
thereon at the date of the redemption for the Debentures.

          d.  If, at any time, a Tax Event or an Investment Company Event (each
as defined below, and each a "Special Event") shall occur and be continuing, the
Subordinated Debt Securities Issuer shall have the right, upon not less than 30
nor more than 60 days notice, to redeem the Subordinated Debt Securities in
whole or in part, for cash within 90 days following the occurrence of such
Special Event, at a redemption price equal to [100%] of the principal amount to
be redeemed plus any accrued and unpaid interest thereon to the date of such
redemption and, following such redemption, Securities with an aggregate
liquidation amount equal to the aggregate principal amount of the Subordinated
Debt Securities so redeemed shall be redeemed by the Trust at the Redemption
Price on a 

                                      A-3
<PAGE>
 
Pro Rata basis in accordance with paragraph 8 hereof. The Common Securities will
be redeemed Pro Rata with the Preferred Securities, except that if an Event of
Default has occurred and is continuing, the Preferred Securities will have
priority over the Common Securities with respect to payment of the Redemption
Price.

            e. The following terms used herein shall be defined as
follows:

               (i) "Investment Company Event" means that the Trust shall have
          received an opinion of counsel experienced in practice under the
          Investment Company Act that, as a result of the occurrence of a change
          in law or regulation or a change in interpretation or application of
          law or regulation by any legislative body, court, governmental agency
          or regulatory authority (a "Change in 1940 Act Law"), there is more
          than an insubstantial risk that the Trust is or will be considered an
          Investment Company which is required to be registered under the
          Investment Company Act, which Change in 1940 Act Law becomes effective
          on or after the date of the Prospectus Supplement.

               (ii) "Tax Event" means that the Trust shall have received an
          opinion of counsel experienced in such matters to the effect that on
          or after the date of the Prospectus Supplement, as a result of (a) any
          amendment to, or change (including any announced proposed change) in,
          the laws (or any regulations thereunder) of the United States or any
          political subdivision or taxing authority therefore or therein, or (b)
          any amendment to, or change in, an interpretation or application of
          any such laws or regulations by any legislative body, court,
          governmental agency or regulatory authority, which amendment or change
          is enacted, promulgated, issued, proposed or announced or which
          interpretation or pronouncement is issued, proposed or announced or
          which action is taken, in each case on or after the date of the
          Prospectus Supplement, there is more than an insubstantial risk that
          (i) the Trust is or will be within 90 days of the date of such
          opinion, subject to United States federal income tax with respect to
          interest accrued or received on the Subordinated Debt Securities, (ii)
          the Trust is, or will be within 90 days of the date of such opinion,
          subject to more than a de minimis amount of taxes, duties or other
          governmental charges, or (iii) interest payable by the Subordinated
          Debt Securities Issuer to the Trust on the Subordinated Debt
          Securities is not, or within 90 days of the date of such opinion will
          not be, deductible, in whole or in part, by the Debt Securities Issuer
          for United States federal income tax purposes.

          f.  The Trust may not redeem fewer than all the outstanding Securities
unless all accrued and unpaid Distributions have been paid on all Securities for
all quarterly Distribution periods terminating on or before the date of
redemption.

          g.  In the event that the Sponsor makes the election referred to in
Section 8.1(a)(v) of the Declaration, the Regular Trustees shall dissolve the
Trust and, after paying or making reasonable provision to pay all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act, cause Subordinated Debt Securities, held by the Property Trustee,
having an aggregate stated liquidation amount of, with an interest rate
identical to the Coupon Rate of, and accrued and unpaid interest equal to
accrued and unpaid Distributions on and having the same record date for payment,
as the Securities, to be distributed to the Holders of the Securities in
liquidation of such Holders' interests in the Trust on a Pro Rata basis in
accordance with paragraph 8 hereof.  On and from the date fixed by the Regular
Trustees for any distribution of Subordinated Debt Securities and dissolution of
the Trust:  (i) the Securities will no longer be deemed to be outstanding, (ii)
The 

                                      A-4
<PAGE>
 
Depository Trust Company (the "Depository") or its nominee (or any successor
Clearing Agency or its nominee), as the record Holder of the Preferred
Securities, will receive a registered global certificate or certificates
representing the Subordinated Debt Securities to be delivered upon such
distribution and (iii) any certificates representing Securities, except for
certificates representing Preferred Securities held by the Depository or
its nominee (or any successor Clearing Agency or its nominee), will be deemed to
represent beneficial interests in the Subordinated Debt Securities having an
aggregate principal amount equal to the aggregate stated liquidation amount of,
with an interest rate identical to the Coupon Rate of, and accrued and unpaid
interest equal to accrued and unpaid Distributions on such Securities until such
certificates are presented to the Subordinated Debt Securities Issuer or its
agent for transfer or reissue.  If the Subordinated Debt Securities are
distributed to Holders of the Securities, pursuant to the terms of the
Indenture, the Subordinated Debt Securities Issuer will use its best efforts to
have the Subordinated Debt Securities listed on the New York Stock Exchange or
on such other exchange as the Preferred Securities were listed immediately prior
to the distribution of the Subordinated Debt Securities.

            h. Redemption or Distribution Procedures.
               ------------------------------------- 

               (i) Notice of any redemption of, or notice of distribution of
          Subordinated Debt Securities in exchange for the Securities (a
          "Redemption/Distribution Notice") will be given by the Trust by mail
          to each Holder of Securities to be redeemed or exchanged not fewer
          than 30 nor more than 60 days before the date fixed for redemption or
          exchange thereof which, in the case of a redemption, will be the date
          fixed for redemption of the Subordinated Debt Securities.  For
          purposes of the calculation of the date of redemption or exchange and
          the dates on which notices are given pursuant to this paragraph
          4(h)(i), a Redemption/Distribution Notice shall be deemed to be given
          on the day such notice is first mailed, by first-class mail, postage
          prepaid, to Holders of Securities.  Each Redemption/Distribution
          Notice shall be addressed to the Holders of Securities at the address
          of each such Holder appearing in the books and records of the Trust.
          No defect in the Redemption/Distribution Notice or in the mailing of
          either thereof with respect to any Holder shall affect the validity of
          the redemption or exchange proceedings with respect to any other
          Holder.

               (ii) In the event that fewer than all the outstanding Securities
          are to be redeemed, the Securities to be redeemed will be redeemed Pro
          Rata from each Holder of Securities, it being understood that, in
          respect of Preferred Securities registered in the name of and held of
          record by DTC (or any successor Clearing Agency) or any other nominee,
          the distribution of the proceeds of such redemption will be made to
          each Clearing Agency Participant (or person on whose behalf such
          nominee holds such securities) in accordance with the procedures
          applied by such agency or nominee.

               (iii)  If Securities are to be redeemed and the Trust gives a
          Redemption/Distribution Notice which notice may only be issued if the
          Subordinated Debt Securities are redeemed as set out in this paragraph
          4 (which notice will be irrevocable) then (A) while the Preferred
          Securities are in book entry only form, with respect to the Preferred
          Securities, by 12:00 noon, New York City time, on the redemption date,
          provided that the Subordinated Debt Securities Issuer has paid the
          Property Trustee a sufficient amount of cash in connection with the
          related redemption or maturity of the Subordinated Debt Securities,
          the Property Trustee will deposit irrevocably with the Depository (or
          successor Clearing Agency) funds sufficient to pay the Redemption
          Price with respect to the Preferred Securities and will give the
          
                                      A-5
<PAGE>
 
          Depository irrevocable instructions and authority to pay the
          Redemption Price to the Holders of the Preferred Securities, and (B)
          if the Preferred Securities are issued in definitive form, with
          respect to the Preferred Securities, and with respect to the Common
          Securities, provided that the Subordinated Debt Securities Issuer has
          paid the Property Trustee a sufficient amount of cash in connection
          with the related redemption or maturity of the Subordinated Debt
          Securities, the Property Trustee will pay the Redemption Price to the
          Holders of such Securities by check mailed to the address of the
          relevant Holder appearing on the books and records of the Trust on the
          redemption date. If a Redemption/Distribution Notice shall have been
          given and funds deposited as required, if applicable, then immediately
          prior to the close of business on the date of such deposit, or on the
          redemption date, as applicable, Distributions will cease to accrue on
          the Securities so called for redemption and all rights of Holders of
          such Securities so called for redemption will cease, except the right
          of the Holders of such Securities to receive the Redemption Price, but
          without interest on such Redemption Price. Neither the Regular
          Trustees nor the Trust shall be required to register or cause to be
          registered the transfer of any Securities which have been so called
          for redemption. If any date fixed for redemption of Securities is not
          a Business Day, then payment of the Redemption Price payable on such
          date will be made on the next succeeding day that is a Business Day
          (and without any interest or other payment in respect of any such
          delay) except that, if such Business Day falls in the next calendar
          year, such payment will be made on the immediately preceding Business
          Day, in each case with the same force and effect as if made on such
          date fixed for redemption. If payment of the Redemption Price in
          respect of Securities is improperly withheld or refused and not paid
          either by the Property Trustee or by the Sponsor as guarantor pursuant
          to the relevant Securities Guarantee, Distributions on such Securities
          will continue to accrue, from the original redemption date to the
          actual date of payment, in which case the actual payment date will be
          considered the date fixed for redemption for purposes of calculating
          the Redemption Price.

               (iv) Redemption/Distribution Notices shall be sent by the Regular
          Trustees on behalf of the Trust to (A) in respect of the Preferred
          Securities, the Depository or its nominee (or any successor Clearing
          Agency or its nominee) if the Global Certificates have been issued or
          if Definitive Preferred Security Certificates have been issued, to the
          Holder thereof, and (B) in respect of the Common Securities, to the
          Holder thereof.

   5.     Voting Rights Applicable to Preferred Securities.
          ------------------------------------------------ 

          a.  Except as provided under paragraphs 5(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Preferred Securities
will have no voting rights.

          b.  Subject to the requirements of the third to last sentence of this
paragraph, the Holders of a Majority in liquidation amount of the Preferred

of conducting any proceeding for any remedy available to the Property

Trustee, or exercising any trust or power conferred upon the Property Trustee
under the Declaration, including (i) directing the time, method, and place of
conducting any proceeding for any remedy available to the Subordinated Debt
Securities Trustee, or exercising any trust or power conferred on the
Subordinated Debt Securities Trustee with respect to the Subordinated Debt
Securities, (ii) waiving any past default and its consequences that is waivable
under Section 5.13 of the Indenture, (iii) exercising any right to rescind or
annul a declaration that the principal of all the Subordinated Debt Securities
shall be due and payable or (iv) consenting to any amendment, modification or
termination of the Indenture or the Subordinated Debt Securities where such
consent shall be required, provided, however, that where a consent under the
Indenture would require the consent or act of the Holders of greater than a
majority in principal amount of Subordinated Debt Securities affected thereby (a
"Super Majority"), the Property Trustee may only give such consent or take such
action at the direction of the Holders of at least the proportion in liquidation
amount of the Preferred Securities which the relevant Super Majority represents
of the aggregate principal amount of the Subordinated Debt Securities
outstanding. The Property Trustee shall not revoke any action previously
authorized or approved by a vote of the Holders of the Preferred Securities.
Other than with respect to directing the time, method and place of conducting
any remedy available to the Property Trustee or the Subordinated Debt Securities
Trustee as set forth above, the Property Trustee shall not take any action in
accordance with the directions of the Holders of the Preferred Securities under
this paragraph unless the Property Trustee has obtained an opinion of tax
counsel to the effect that for the purposes of United States federal income tax
the Trust will not be classified as other than a grantor trust on account of
such action. If the Property Trustee fails to enforce its rights under the
Declaration, any Holder of Preferred Securities may, to the fullest extent
permitted by law, institute a legal proceeding directly against any Person to
enforce the Property Trustee's rights under the Declaration, without first
instituting a legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing with respect to the Preferred Securities and such event is
attributable to the failure of the Subordinated Debt Securities Issuer to pay
interest, premium, if any, or principal on the Subordinated Debt Securities on
the date such interest, premium, if any, or principal is otherwise payable (or
in the case of redemption, on the redemption date), then a holder of Preferred
Securities may institute a Direct Action for enforcement of payment to such
holder of the principal of, premium, if any, or interest on, Subordinated Debt
Securities having a principal amount equal to the aggregate liquidation amount
of the Preferred Securities of such holder on or after the respective due date
specified in the Subordinated Debt Securities. Notwithstanding any payments made
to such Holder of Preferred Securities by the Subordinated Debt Securities
Issuer in connection with a Direct Action, the Subordinated Debt Securities
Issuer shall remain obligated to pay the principal of, premium, if any, and
interest on the Subordinated Debt Securities held by the Trust or the Property
Trustee, and the Subordinated Debt Securities Issuer shall be subrogated to the
rights of the Holder of such Preferred Securities with respect to payments on
the Preferred Securities to the extent of any payment made by the Subordinated
Debt Securities Issuer to such Holder in any Direct Action. Except as provided
in the preceding sentences, the Holders of Preferred Securities will not be able
to exercise directly any other remedy available to the holders of the
Subordinated Debt Securities.

          c.  Any approval or direction of Holders of Preferred Securities may
be given at a separate meeting of Holders of Preferred Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote to be
mailed to each Holder of record of Preferred Securities. Each such notice will
include a statement setting forth (i) the date of such meeting, (ii) a
description of any resolution proposed for adoption at such meeting on which
such Holders are entitled to vote and (iii) instructions for the delivery of
proxies.

                                      A-7
<PAGE>
 
          d.  No vote or consent of the Holders of the Preferred Securities will
be required for the Trust to redeem and cancel Preferred Securities or to
distribute the Subordinated Debt Securities in accordance with the Declaration
and the terms of the Securities.

          e.  Notwithstanding that Holders of Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

     6.   Voting Rights With Respect to Common Securities.
          ----------------------------------------------- 

          a.  Except as provided under paragraphs 6(b), 6(c) and 7 and as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

          b.  The Holders of the Common Securities are entitled, in accordance
with Article V of the Declaration, to vote to appoint, remove or replace any
Trustee or to increase or decrease the number of Trustees.

          c.  Subject to Section 2.6 of the Declaration and only after all
Events of Default with respect to the Preferred Securities have been cured,
waived or otherwise eliminated and subject to the requirements of the second to
last sentence of this paragraph, the Holders of a Majority in liquidation amount
of the Common Securities, voting separately as a class, may direct 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 the Declaration, including (i) directing the time, method, place
of conducting any proceeding for any remedy available to the Subordinated Debt
Securities Trustee, or exercising any trust or power conferred on the
Subordinated Debt Securities Trustee with respect to the Subordinated Debt
Securities, (ii) waiving any past default and its consequences that is waivable
under Section 513 of the Indenture, or (iii) exercising any right to rescind or
annul a declaration that the principal of all the Subordinated Debt Securities
shall be due and payable, provided, however, that where a consent or action
under the Indenture would require the consent or act of the Holders of greater
than a majority in principal amount of Debentures affected thereby (a "Super
Majority"), the Property Trustee may only give such consent or take such action
at the direction of the Holders of at least the proportion in liquidation amount
of the Common Securities which the relevant Super Majority represents of the
aggregate principal amount of the Subordinated Debt Securities outstanding.
Pursuant to this paragraph 6(c), the Property Trustee shall not revoke any
action previously authorized or approved by a vote of the Holders of the Common
Securities.  Other than with respect to directing the time, method and place of
conducting any remedy available to the Property Trustee or the Subordinated Debt
Securities Trustee as set forth above, the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Common Securities
under this paragraph unless the Property Trustee has obtained an opinion of tax
counsel to the effect that for the purposes of United States federal income tax
the Trust will not be classified as other than a grantor trust on account of
such action.  If the Property Trustee fails to enforce its rights under the
Declaration, any Holder of Common Securities may, to the fullest extent
permitted by law, institute a legal proceeding directly against any Person to
enforce the Property Trustee's rights under the Declaration, without first
instituting a legal proceeding against the Property Trustee or any other Person.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing with respect to the Common Securities and such event is attributable
to the failure of the Subordinated Debt Securities Issuer to pay interest or
principal on the Subordinated Debt Securities on the date such interest or
principal is otherwise payable (or in the case of redemption, on the redemption
date), then a holder of Common Securities may institute a proceeding for

                                      A-8
<PAGE>
 
enforcement of payment to such holder of the principal of, or interest on,
Subordinated Debt Securities having a principal amount equal to the aggregate
liquidation amount of the Common Securities of such holder on or after the
respective due date specified in the Subordinated Debt Securities.

          d.  Any approval or direction of Holders of Common Securities may be
given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written Consent. The Regular Trustees will cause a notice of any
meeting at which Holders of Common Securities are entitled to vote, to be mailed
to each Holder of record of Common Securities. Each such notice will include a
statement setting forth (i) the date of such meeting, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote and (iii) instructions for the delivery of proxies.
          e.  No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
the Subordinated Debt Securities in accordance with the Declaration and the
terms of the Securities.

     7.   Amendments to Declaration and Indenture.
          --------------------------------------- 

          a.  In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 or Section 3.14 of the Declaration, then the Holders of outstanding
Securities as a class, will be entitled to vote on such amendment or proposal
(but not on any other 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 Securities, voting together as a single
class; provided, however, that if any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or the
Common Securities, then only the affected 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 a Majority in liquidation amount of such class of
Securities.

          b.  In the event the consent of the Property Trustee as the holder of
the Subordinated Debt Securities is required under the Indenture with respect to
any amendment, modification or termination of the Indenture or the Subordinated
Debt Securities, the Property Trustee shall request the direction of the Holders
of the Securities with respect to such amendment, modification or termination
and shall vote with respect to such amendment, modification or termination as
directed by a Majority in liquidation amount of the Securities voting together
as a single class; provided, however, that where a consent under the Indenture
would require the consent of the Holders of greater than a majority in aggregate
principal amount of the Debentures (a "Super Majority"), the Property Trustee
may only give such consent at the direction of the Holders of at least the
proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; provided, further, that the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Securities under
this paragraph 7(b) unless the Property Trustee has been furnished an opinion of
tax counsel to the effect that for the purposes of United States federal income
tax the Trust will not be classified as other than a grantor trust on account of
such action.

     8.     Pro Rata.
            -------- 

     A reference in these terms of the Securities to any payment, distribution
or treatment as being "Pro Rata" shall mean pro rata to each Holder of
Securities according to the aggregate liquidation amount of the Securities held
by the relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, in relation to a payment, an Event of Default
under the Indenture has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.

     9.     Ranking.
            ------- 

     The Preferred Securities rank pari passu and payment thereon shall be made
Pro Rata with the Common Securities except that, where an Event of Default
occurs and is continuing under the Indenture in respect of the Subordinated Debt
Securities held by the Property Trustee, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Preferred Securities.

     10.    Acceptance of Securities Guarantee and Indenture.
            ------------------------------------------------ 

     Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

     11.    No Preemptive Rights.
            -------------------- 

     The Holders of the Securities shall have no preemptive or similar rights to
subscribe for any additional Securities.

     12.    Miscellaneous.
            ------------- 

     These terms constitute a part of the Declaration.

     The Sponsor will provide a copy of the Declaration, the Preferred
Securities Guarantee and the Indenture to a Holder without charge on written
request to the Trust at its principal place of business.

  Re: Registration Statement on Form S-3 of Sempra Energy, Sempra Holdings,
     Inc., Sempra Energy Capital Trust I, Sempra Energy Capital Trust II and
     Sempra Energy Capital Trust III
  --------------------------------------------------------------------
 
Ladies and Gentlemen:
 
  I am the Executive Vice President and General Counsel of Sempra Energy, a
California corporation. In connection with the registration statement on Form
S-3 filed on May 5, 1999 (the "Registration Statement") by Sempra Energy, a
California Corporation, Sempra Holdings, a California corporation, Sempra
Energy Capital Trust I, a Delaware Trust, Sempra Energy Capital Trust II, a
Delaware Trust, and Sempra Energy Capital Trust III, a Delaware Trust
(collectively, the "Registrants") with the Securities and Exchange Commission
(the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act"), you have requested my opinion with respect to the matters
set forth below.
 
  I have reviewed the prospectus (the "Prospectus") which is a part of the
Registration Statement. The Prospectus provides that it will be supplemented in
the future by one or more supplements to the Prospectus (each a "Prospectus
Supplement"). The Prospectus as supplemented by various Prospectus Supplements
will provide for the registration of up to $1,000,000,000 aggregate offering
price of (i) one or more series of unsecured senior or subordinated debt
securities (the "Debt Securities") which may be issued by Sempra Energy or
Sempra Energy Holdings, (ii) shares of common stock, without par value, which
may be issued by Sempra Energy (the "Common Stock"), (iii) shares of preferred
stock, without par value, which may be issued by Sempra Energy (the "Preferred
Stock"), (iv) preferred securities (the "Preferred Securities") which may be
issued by each Trust pursuant to their respective Amended and Restated
Declarations of Trust (each an "Amended Declaration") and (v) guarantees of the
Preferred Securities, which may be issued by Sempra Energy (the "Preferred
Securities Guarantees"), and the Debt Securities issued by Sempra Energy
Holdings (the "Debt Securities Guarantees" and, together with the Preferred
Securities Guarantees, the "Guarantees") described below pursuant to one or
more guarantee agreements (each a "Guarantee Agreement"). The Debt Securities,
the Guarantees and the Common and Preferred Stock are collectively referred to
herein as the "Securities." Any Debt Securities may be exchangeable and/or
convertible into shares of Common Stock. The Debt Securities may be issued
pursuant to one or more indentures and one or more supplements thereto
(collectively, the "Indentures"), in each case between Sempra Energy or Sempra
Holdings and a trustee (each, a "Trustee").
<PAGE>
 
  In my capacity as General Counsel, I am generally familiar with the
proceedings taken and proposed to be taken by the Registrants in connection
with the authorization and issuance of the Securities. For purposes of this
opinion, I have assumed that such proceedings will be timely and properly
completed, in accordance with all requirements of applicable federal, Delaware,
California and New York laws, in the manner presently proposed.
 
  I have made such legal and factual examinations and inquiries, including an
examination of originals and copies certified or otherwise identified to my
satisfaction, of all such documents, corporation records and instruments of the
Registrants as I have deemed necessary or appropriate for purposes of this
opinion. In my examination, I have assumed the genuineness of all signatures,
the authenticity of all documents submitted to me as originals, and the
conformity to authentic original documents of all documents submitted to me as
copies.
 
  I have been furnished with, and with your consent have exclusively relied
upon, certificates of officers of Sempra Energy with respect to certain factual
matters. In addition, I have obtained and relied upon such certificates and
assurances from public officials as I have deemed necessary.
 
  I am opining herein as to the effect on the subject transaction only of the
federal securities laws of the United States, the General Corporation Law of
the State of Delaware and the State of California and with respect to opinion
paragraphs 1, 2 and 3 below, the internal laws of the State of New York, and I
express no opinion with respect to the applicability thereto, or the effect
thereon, of the laws of any other jurisdiction or, in the case of Delaware and
California, any other laws, or as to any matters of municipal law or the laws
of any local agencies within any state.
 
  Subject to the foregoing and the other qualifications set forth herein, it is
my opinion that, as of the date hereof:
 
  1. When (a) the Debt Securities have been duly established in accordance with
the terms of the applicable Indentures (including, without limitation, the
adoption by the Board of Directors of Sempra Energy and/or Sempra Energy
Holdings of any necessary further resolutions duly authorizing the issuance and
delivery of the Debt Securities), duly authenticated by the Trustee and duly
executed and delivered on behalf of Sempra Energy and/or Sempra Energy Holdings
against payment therefor in accordance with the terms and provisions of the
applicable Indenture and as contemplated by the Registration Statement, the
Prospectus and the related Prospectus Supplement(s), and (b) when each of the
Registration Statement and any required post-effective amendment thereto have
all become effective under the Securities Act and (c) assuming that the terms
of the Debt Securities as executed and delivered are as described in the
Registration Statement, the Prospectus and the related prospectus
Supplement(s), and (d) assuming that the Debt Securities as executed and
delivered do not violate any law applicable to the issuing company or result in
a default under or breach of any agreement or instrument binding upon the
issuing company, and (e) assuming that the Debt Securities as executed and
delivered comply with all requirements and restrictions, if any, applicable to
the issuing company, whether imposed by any court or governmental or regulatory
body having jurisdiction over the issuing company, and (f) assuming that the
Debt Securities are then issued and sold as contemplated in the Registration
Statement, the Prospectus and the related Prospectus Supplement(s), the Debt
Securities will constitute valid and legally binding obligations of the issuing
company enforceable against the issuing company in accordance with the terms of
the Debt Securities.
<PAGE>
 
  2. When (a) the Debt Securities Guarantees and the related Debt Securities
have been duly established in accordance with the terms of the applicable
Indentures (including, without limitation, the adoption by the Board of
Directors of Sempra Energy of any necessary further resolutions duly
authorizing the issuance and delivery of the Debt Securities Guarantees and the
related Debt Securities), the Debt Securities Guarantees have been duly
executed and delivered and the related Debt Securities have been authenticated
by the Trustee and duly executed and delivered on behalf of Sempra Energy
against payment therefor in accordance with the terms and provisions of the
applicable Indenture and as contemplated by the Registration Statement, the
Prospectus and the related Prospectus Supplement(s), and (b) when each of the
Registration Statement and any required post-effective amendment thereto have
all become effective under the Securities Act, and (c) assuming that the terms
of the Debt Securities Guarantees as executed and delivered are as described in
the Registration Statement, the Prospectus and the related Prospectus
Supplement(s), and (d) assuming that the Debt Securities Guarantees as executed
and delivered do not violate any law applicable to Sempra Energy or result in a
default under or breach of any agreement or instrument binding upon Sempra
Energy, and (e) assuming that the Debt Securities Guarantees as executed and
delivered comply with all requirements and restrictions, if any, applicable to
Sempra Energy, whether imposed by any court or governmental or regulatory body
having jurisdiction over Sempra Energy, and (f) assuming that the Debt
Securities Guarantees are then issued as contemplated in the Registration
Statement, the Prospectus and the related Prospectus Supplement(s), the Debt
Securities Guarantees will constitute valid and legally binding obligations of
Sempra Energy, enforceable against Sempra Energy in accordance with the terms
of the Debt Securities Guarantees.
 
  3. With respect to the Preferred Securities Guarantees, when (i) the trustees
of the applicable Trust have taken all necessary action to adopt the Amended
Declaration and to fix and determine the terms of the applicable Preferred
Securities in accordance with the terms of the applicable Amendment
Declaration; (ii) the appropriate officers of Sempra Energy have taken all
necessary action to fix and determine the terms of the applicable Preferred
Securities Guarantees in accordance with the resolutions adopted by the Board
of Directors of Sempra Energy relating to the issuance and delivery of the
Preferred Securities; (iii) the terms of the applicable Preferred Securities
and the related Preferred Securities Guarantee and the issuance and sale
thereof have been duly established in conformity with the applicable amended
Declaration and applicable Guarantee Agreement, respectively, so as not to
violate any applicable law, the applicable Certificate of Trust, Declaration of
Trust and Amended Declaration, and the Articles of Incorporation and By-laws of
Sempra Energy, or result in a default under or breach of any agreement or
instrument binding upon the applicable Trust or Sempra Energy; (iv) the
applicable Guarantee Agreement has been duly executed and delivered; (v) the
applicable Preferred Securities have been duly issued and delivered by the
applicable Trust as contemplated by the Registration Statement and the
prospectus supplement relating thereto; (vi) certificates representing the
applicable Preferred Securities have been manually authenticated by an
authorized officer of the applicable Property Trustee (as defined in the
applicable Amended Declaration) for the applicable Preferred Securities and
registered by such Property Trustee and delivered to the purchasers thereof;
(vii) the applicable Trust receives the agreed-upon consideration therefor and
(viii) the applicable Guarantee Agreement shall have been qualified under the
Trust Indenture Act of 1939, as amended, the applicable Preferred Securities
Guarantee will be a valid and binding obligation of Sempra Energy enforceable
in accordance with its terms.
 
  4. Sempra Energy has the authority pursuant to its Articles of Incorporation
to issue up to 750,000,000 shares of Common Stock and 50,000,000 shares of
Preferred Stock. Upon adoption by the Board of Directors of Sempra Energy of
any necessary further resolutions in form and content as required by applicable
law and upon issuance and delivery of and payment for such shares in the
<PAGE>
 
manner contemplated by the Registration Statement, the Prospectus and the
related Prospectus Supplement(s) and by such resolution, such shares of common
Stock (including any Common Stock duly issued upon the exchange or conversion
of Debt Securities that are exchangeable or convertible into Common Stock) or
Preferred Stock will be validly issued, fully paid and nonassessable.
 
  The opinions set forth in paragraphs 1 through 4 above are subject to the
following exceptions, limitations and qualifications: (i) the effect of
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to or affecting the rights and remedies of
creditors; (ii) the effect of general principles of equity, including without
limitation, concepts of materiality, reasonableness, good faith and fair
dealing and the possible unavailability of specific performance or injunctive
relief, regardless of whether enforcement is considered in a proceeding in
equity or at law, and the discretion of the court before which any proceeding
therefor may be brought; (iii) the unenforceability under certain circumstances
under law or court decisions of provisions providing for the indemnification
of, or contribution to, a party with respect to a liability where such
indemnification or contribution is contrary to public policy; (iv) requirements
that a claim with respect to any Guarantee denominated other than in United
States dollars (or a judgment denominated other than in United States dollars
in respect of such claim) be converted into United States dollars at a rate of
exchange prevailing on a date determined pursuant to applicable law;
(v) governmental authority to limit, delay or prohibit the making of payments
outside the United States or in a foreign currency, composite currency or
current unit; (vi) I express no opinion concerning the enforceability of any
waiver of rights or defenses with respect to stay, extension or usury laws; and
(vii) I express no opinion with respect to whether acceleration of Debt
Securities may affect the collectibility of any portion of the stated principle
amount thereof which might be determined to constitute unearned interest
thereon.
 
  I have assumed for purposes of this opinion that the applicable Indenture
constitutes the legally valid, binding and enforceable obligation of each of
Sempra Energy and Sempra Energy Holdings enforceable against each of Sempra
Energy and Sempra Energy Holdings in accordance with its terms; and that
Trustee for each Indenture is duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization; that the Trustee
is duly qualified to engage in the activities contemplated by the applicable
Indenture; that the applicable Indenture has been duly authorized, executed and
delivered by the Trustee and constitutes a legally valid, binding and
enforceable obligation of the Trustee, enforceable against the Trustee in
accordance with its terms; and the Trustee is in compliance, generally and with
respect to acting as Trustee under the applicable Indenture, with all
applicable laws and regulations; and that the Trustee has the requisite
organizational and legal power and authority to perform its obligations under
the applicable Indenture.
 
  I consent to your filling this opinion as an exhibit to the Registration
Statement and to the reference to me under the caption "Validity of the
Securities and the Guarantees" in the Prospectus included therein.
 
                                          Very truly yours,

     Re:  Sempra Energy Capital Trust I
          -----------------------------

Ladies and Gentlemen:

          We have acted as special Delaware counsel for Sempra Energy, a

Delaware business trust (the "Trust"), in connection with the matters set forth

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a) The Certificate of Trust of the Trust, dated as of April 22, 1999

the holders, from time to time, of undivided beneficial interests in the assets

below);

          (d) The Registration Statement on Form S-3 (the "Registration

and collectively, the "Preferred Securities"), as proposed to be filed by the
Company, the Trust and others with the Securities and Exchange Commission on or
about May 5, 1999; and

          (e) A Certificate of Good Standing for the Trust, dated May 5, 1999,
obtained from the Secretary of State.

          Initially capitalized terms used herein and not otherwise defined are
used as defined in the Declaration.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (e) above.  In particular,
we have not reviewed any document (other than the documents listed in paragraphs
(a) through (e) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

          For purposes of this opinion, we have assumed (i) that the Declaration
and the Certificate are in full force and effect and have not been amended, (ii)
except to the extent provided in paragraph 1 below, the due creation or due
organization or due formation, as the case may be, and valid existence in good
standing of each party to the documents examined by us under the laws of the
jurisdiction governing its creation, organization or formation, (iii) the legal
capacity of natural persons who are parties to the documents examined by us,
(iv) that each of the parties to the documents examined by us has the power and
authority to execute and deliver, and to perform its obligations under, such
documents, (v) the due authorization, execution and delivery by all parties
thereto of all documents examined by us, (vi) the receipt by each Person to whom
a Preferred Security is to be issued by the Trust (collectively, the "Preferred
Security Holders") of a preferred security certificate for such Preferred
Security and the payment for the Preferred Security acquired by it, in
accordance with the Declaration and the Registration Statement, and (vii) that
the Preferred Securities are issued and sold to the Preferred Security Holders

responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on

the laws of any other jurisdiction, including federal laws and rules and
regulations relating thereto. Our opinions are rendered only with respect to
Delaware laws and rules, regulations and orders thereunder that are currently in
effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

          2.  The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.  The Preferred Security Holders, as beneficial owners of the Trust,
will 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.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Declaration.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Validity of the
Securities and the Guarantees" in the Prospectus.  In giving the foregoing
consents, we do not thereby admit that we come within the category of Persons

opinion may not be furnished or quoted to, or relied upon by, any other Person
for any purpose.

                              Very truly yours,

the laws of any other jurisdiction, including federal laws and rules and
regulations relating thereto. Our opinions are rendered only with respect to
Delaware laws and rules, regulations and orders thereunder that are currently in
effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.  The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

          2.  The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

          3.  The Preferred Security Holders, as beneficial owners of the Trust,
will 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.  We note that the Preferred Securities
Holders may be obligated to make payments as set forth in the Declaration.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Validity of the
Securities and the Guarantees" in the Prospectus.  In giving the foregoing
consents, we do not thereby admit that we come within the category of Persons
whose consent is required under Section 7 of the Securities Act of 1933, as
amended, or the rules and regulations of the Securities and Exchange Commission
thereunder.  Except as stated above, without our prior written consent, this
opinion may not be furnished or quoted to, or relied upon by, any other Person
for any purpose.

                              Very truly yours,
