                                  THE COMPANY
 
GENERAL
 
     TriNet Corporate Realty Trust, Inc. is real estate investment trust (a
"REIT") which acquires, owns and manages predominantly office and industrial
properties net leased to corporations nationwide, including corporate
headquarters and strategically important distribution facilities. Under a net
lease, the tenant is responsible for obligations such as taxes, repairs and
insurance, which would otherwise be the responsibility of the landlord. Based on
total market capitalization, the Company is one of the largest publicly traded
REITs in the United States engaged exclusively in the corporate net leased real
estate business. As of December 27, 1996, TriNet's portfolio consists of 77
properties (the "Properties"), which are predominantly single-tenant industrial
and office buildings located throughout the United States. The Properties are
100% net leased pursuant to leases with an average remaining term (excluding
extension options) of approximately 9.5 years when lease terms are weighted
according to contractual rent revenues. TriNet is a self-administered and self-
managed REIT.
 
     The Company was incorporated under the laws of the State of Maryland on
March 4, 1993. The Company's principal executive offices are located at Four
Embarcadero Center, Suite 3150, San Francisco, California 94111, and its
telephone number is (415) 391-4300. The Company also maintains regional offices
in Florida and Pennsylvania.
 
                               USE OF PROCEEDS
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Company intends to use the net proceeds from the sale of Securities for general
corporate purposes, which may include the acquisition of additional properties,
the repayment of outstanding debt or the improvement of certain properties
already in the Company's portfolio.
 
                 RATIOS OF EARNINGS TO COMBINED FIXED CHARGES
                        AND PREFERRED STOCK DIVIDENDS
 
     The Company's ratio of earnings to combined fixed charges and preferred
stock dividends for the nine months ended September 30, 1996 was 2.06x. The
Company's historical ratios of earnings to fixed charges for the nine months
ended September 30, 1995 and for the years ended December 31, 1995, 1994, 1993
and 1992 were 1.92x, 1.97x, 2.65x, 2.17x and 1.12x, respectively. For the year
ended December 31, 1991, earnings were insufficient to cover fixed charges by
$532,000.
 
     The ratios of (i) earnings to fixed charges and (ii) earnings to combined
fixed charges and preferred stock dividends were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of pre-tax income from
continuing operations plus fixed charges (excluding preferred stock dividends).
Fixed charges consist of interest expense and the amortization of debt issuance
costs, and with respect to the ratio of earnings to combined fixed charges and
preferred stock dividends, preferred stock dividend requirements. For the
periods presented, the Company had no capitalized interest.
 
                        DESCRIPTION OF DEBT SECURITIES
 
     The Debt Securities will be direct unsecured obligations of the Company and
may be either senior Debt Securities ("Senior Debt Securities") or subordinated
Debt Securities ("Subordinated Debt Securities").
 
                                        3
<PAGE>   5
 
The Debt Securities will be issued under one or more indentures, each dated as
of a date prior to the issuance of the Debt Securities to which it relates.
Senior Debt Securities and Subordinated Debt Securities may be issued pursuant
to separate indentures (respectively, a "Senior Indenture" and a "Subordinated
Indenture"), in each case between the Company and a trustee (a "Trustee"), which
may be the same Trustee, and in the form that has been filed as an exhibit to
the Registration Statement of which this Prospectus is a part, subject to such
amendments or supplements as may be adopted from time to time. The Senior
Indenture and the Subordinated Indenture, as amended or supplemented from time
to time, are sometimes hereinafter referred to collectively as the "Indentures."
The Indentures will be subject to and governed by the Trust Indenture Act of
1939, as amended (the "TIA"). The statements made under this heading relating to
the Debt Securities and the Indentures are summaries of the anticipated
provisions thereof, do not purport to be complete and are qualified in their
entirety by reference to the Indentures and such Debt Securities.
 
     Capitalized terms used herein and not defined shall have the meanings
assigned to them in the applicable Indenture.
 
TERMS
 
     General.  The Debt Securities will be direct, unsecured obligations of the
Company. Unless otherwise indicated in the applicable Prospectus Supplement, the
indebtedness represented by the Senior Debt Securities will rank equally with
all other unsecured and unsubordinated indebtedness of the Company. The
indebtedness represented by Subordinated Debt Securities will be subordinated in
right of payment to the prior payment in full of Senior Indebtedness of the
Company as described under "-- Subordination." The particular terms of the Debt
Securities offered by a Prospectus Supplement will be described in the
applicable Prospectus Supplement, along with any applicable modifications of or
additions to the general terms of the Debt Securities as described herein and in
the applicable Indenture and any applicable federal income tax considerations.
Accordingly, for a description of the terms of any series of Debt Securities,
reference must be made to both the Prospectus Supplement relating thereto and
the description of the Debt Securities set forth in this Prospectus.
 
     Except as set forth in any Prospectus Supplement, the Debt Securities may
be issued without limit as to aggregate principal amount, in one or more series,
in each case as established from time to time by the Company or as set forth in
the applicable Indenture or in one or more indentures supplemental to such
Indenture. All Debt Securities of one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the holders of the Debt Securities of such series, for issuance of additional
Debt Securities of such series.
 
     Each Indenture will provide that the Company may, but need not, designate
more than one Trustee thereunder, each with respect to one or more series of
Debt Securities. Any Trustee under an Indenture may resign or be removed with
respect to one or more series of Debt Securities, and a successor Trustee may be
appointed to act with respect to such series. In the event that two or more
persons are acting as Trustee with respect to different series of Debt
Securities, each such Trustee shall be a Trustee of a trust under the applicable
Indenture separate and apart from the trust administered by any other Trustee,
and, except as otherwise indicated herein, any action described herein to be
taken by each Trustee may be taken by each such Trustee with respect to, and
only with respect to, the one or more series of Debt Securities for which it is
Trustee under the applicable Indenture.
 
     The following summaries set forth certain general terms and provisions of
the Indentures and the Debt Securities. The Prospectus Supplement relating to

     authorized form and denomination and the circumstances under which any such
     exchanges may occur, if other than in the manner provided in the Indenture,
     and, if Registered Securities of the series are to be issuable as a Global
     Security (as defined), the identity of the depository for such series;
 
          (18) The date as of which any Bearer Securities of the series and any

     of business on the Regular Record Date for such interest, the manner in
     which, or the Person to whom, any interest on any Bearer Security of the

     price or rate, the conversion period, any adjustment of the applicable
     conversion price and any requirements relative to the reservation of such
     shares for purposes of conversion); and
 
          (23) Any other terms of the series (which terms shall not be
     inconsistent with the provisions of the Indenture under which the Debt
     Securities are issued).
 
     If so provided in the applicable Prospectus Supplement, the Debt Securities
may be issued at a discount below their principal amount and provide for less
than the entire principal amount thereof to be payable upon declaration of
acceleration of the maturity thereof ("Original Issue Discount Securities"). In
such cases, all material U.S. federal income tax, accounting and other
considerations applicable to Original Issue Discount Securities will be
described in the applicable Prospectus Supplement.
 
     Except as may be set forth in any Prospectus Supplement, the Debt
Securities will not contain any provisions that would limit the ability of the
Company to incur indebtedness or that would afford holders of Debt Securities
protection in the event of a highly leveraged or similar transaction involving
the Company or in the event of a change of control. Restrictions on ownership
and transfers of the Common Stock and Preferred Stock are designed to preserve
its status as a REIT and, therefore, may act to prevent or hinder a
 
                                        6
<PAGE>   8
 
change of control. See "Restrictions on Transfers of Capital Stock." Reference
is made to the applicable Prospectus Supplement for information with respect to
any deletions from, modifications of, or additions to, the events of default or
covenants of the Company that are described below, including any addition of a
covenant or other provision providing event risk or similar protection.
 
DENOMINATION, INTEREST, REGISTRATION AND TRANSFER
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Debt Securities of any series will be issuable in denominations of $1,000 and
integral multiples thereof. Where Debt Securities of any series are issued in
bearer form, the special restrictions and considerations, including special
offering restrictions and special federal income tax considerations, applicable
to any such Debt Securities and to payment on and transfer and exchange of such
Debt Securities will be described in the applicable Prospectus Supplement.
Bearer Debt Securities will be transferable by delivery.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium or Make-Whole Amount, if any) and interest
on any series of Debt Securities will be payable at the corporate trust office
of the applicable Trustee, the address of which will be stated in the applicable
Prospectus Supplement; provided that, at the option of the Company, payment of
interest may be made by check mailed to the address of the person entitled
thereto as it appears in the applicable register for such Debt Securities or by
wire transfer of funds to such person at an account maintained within the United
States.
 
     Any interest not punctually paid or duly provided for on any Interest
Payment Date with respect to a Debt Security in registered form ("Defaulted
Interest") will forthwith cease to be payable to the holder on the applicable
Regular Record Date and may either be paid to the Person in whose name such Debt
Security is registered at the close of business on a special record date (the
"Special Record Date") for the payment of such Defaulted Interest to be fixed by
the Trustee, in which case notice thereof shall be given to the holder of such
Debt Security not less than 10 days prior to such Special Record Date, or may be
paid at any time in any other lawful manner, all as more completely described in
the applicable Indenture.
 
     Subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series will be exchangeable for any
authorized denomination of other Debt Securities of the same series and of a
like aggregate principal amount and tenor upon surrender of such Debt Securities
at the corporate trust office of the applicable Trustee or at the office of any
transfer agent designated by the Company for such purpose. In addition, subject
to certain limitations imposed upon Debt Securities issued in book-entry form,
the Debt Securities of any series may be surrendered for registration of
transfer or exchange thereof at the corporate trust office of the applicable
Trustee or at the office of any transfer agent designated by the Company for
such purpose. Every Debt Security in registered form surrendered for
registration of transfer or exchange must be duly endorsed or accompanied by a
written instrument of transfer, and the person requesting such action must
provide evidence of title and identity satisfactory to the applicable Trustee or
transfer agent. No service charge will be made for any registration of transfer
or exchange of any Debt Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. If the applicable Prospectus Supplement refers to any transfer agent
(in addition to the applicable Trustee) initially designated by the Company with
respect to any series of Debt Securities, the Company may at any time rescind
the designation of any such transfer agent or approve a change in the location
through which any such transfer agent acts, except that the Company will be
required to maintain a transfer agent in each place of payment for such series.
The Company may at any time designate additional transfer agents with respect to
any series of Debt Securities.
 
     Neither the Company nor any Trustee shall be required to (a) issue,
register the transfer of or exchange Debt Securities of any series during a
period beginning at the opening of business 15 days before the selection of any
Debt Securities for redemption and ending at the close of business on the day of
mailing of the notice of redemption; (b) register the transfer of or exchange
any Debt Security, or portion thereof, so selected for redemption, in whole or
in part, except the unredeemed portion of any Debt Security being redeemed in
part; or (c) issue, register the transfer of or exchange any Debt Security that
has been surrendered for repayment at the option of the holder, except the
portion, if any, of such Debt Security not to be so repaid.
 
                                        7
<PAGE>   9
 
     Payment in respect of Debt Securities in bearer form will be made in the
currency and in the manner designated in the applicable Prospectus Supplement,
subject to any applicable laws and regulations, at such paying agencies outside
the United States as the Company may appoint from time to time. The paying
agents outside the United States, if any, initially appointed by the Company for
a series of Debt Securities will be named in the Prospectus Supplement. Unless
otherwise provided in the applicable Prospectus Supplement, the Company may at
any time designate additional paying agents or rescind the designation of any
paying agents, except that, if Debt Securities of a series are issuable in
registered form, the Company will be required to maintain at least one paying
agent in each place of payment for such series and if Debt Securities of a
series are issuable in bearer form, the Company will be required to maintain at
least one paying agent in a place of payment outside the United States where
Debt Securities of such series and any coupons appertaining thereto may be
presented and surrendered for payment.
 
MERGER, CONSOLIDATION OR SALE OF ASSETS
 
     The Indentures will provide that the Company may, without the consent of
the holders of any outstanding Debt Securities, consolidate with, or sell, lease
or convey all or substantially all of its assets to, or merge with or into, any
other entity provided that (a) either the Company shall be the continuing
entity, or the successor entity (if other than the Company) formed by or
resulting from any such consolidation or merger or which shall have received the
transfer of such assets is organized under the laws of any domestic jurisdiction
and assumes the Company's obligations to pay principal of (and premium or
Make-Whole Amount, if any) and interest on all of the Debt Securities and the
due and punctual performance and observance of all of the covenants and
conditions contained in such Indenture; (b) immediately after giving effect to
such transaction and treating any indebtedness that becomes an obligation of the
Company or any subsidiary as a result thereof as having been incurred by the
Company or such subsidiary at the time of such transaction, no Event of Default
under such Indenture, and no event which, after notice or the lapse of time, or
both, would become such an Event of Default, shall have occurred and be
continuing; and (c) an officers' certificate and legal opinion covering such
conditions shall be delivered to each Trustee.
 
CERTAIN COVENANTS
 
     The applicable Prospectus Supplement will describe any material covenants
in respect of a series of Debt Securities that are not described in this
Prospectus. Unless otherwise indicated in the applicable Prospectus Supplement,
Senior Debt Securities will include the following covenants of the Company:
 
     Existence.  Except as permitted under "-- Merger, Consolidation or Sale of
Assets," the Indentures will require the Company to do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (by articles of incorporation, by-laws and statute) and
franchises; provided, however, that the Company shall not be required to
preserve any right or franchise if its Board of Directors determines that the
preservation thereof is no longer desirable in the conduct of its business.
 
     Maintenance of Properties.  The Indentures will require the Company to
cause all of its material properties used or useful in the conduct of its
business or the business of any subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that the
Company and its subsidiaries shall not be prevented from selling or otherwise
disposing of their properties for value in the ordinary course of business.
 
     Insurance.  The Indentures will require the Company to cause each of its
and its subsidiaries' insurable properties to be insured against loss or damage
at least equal to their then full insurable value with insurers of recognized
responsibility and, if described in the applicable Prospectus Supplement, having
a specified rating from a recognized insurance rating service.
 
     Payment of Taxes and Other Claims.  The Indentures will require the Company
to pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon it or any subsidiary or upon the income, profits or property of the
Company or any subsidiary and (ii) all lawful claims for labor, materials and
supplies which, if unpaid,
 
                                        8
<PAGE>   10
 
might by law become a lien upon the property of the Company or any subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     Unless otherwise provided in the applicable Prospectus Supplement, each
Indenture will provide that the following events are "Events of Default" with
respect to any series of Debt Securities issued thereunder: (a) default in the
payment of any interest on any Debt Security of such series when such interest
becomes due and payable that continues for a period of 30 days; (b) default in
the payment of the principal of (or premium or Make-Whole Amount, if any, on)
any Debt Security of such series when due and payable; (c) default in making any
sinking fund payment as required for any Debt Security of such series; (d)
default in the performance, or breach, of any other covenant or warranty of the
Company in the applicable Indenture with respect to the Debt Securities of such
series and continuance of such default or breach for a period of 60 days after
written notice as provided in the Indenture; (e) default under any bond,
debenture, note, mortgage, indenture or instrument under which there may be
issued or by which there may be secured or evidenced any indebtedness for money
borrowed by the Company (or by any Subsidiary, the repayment of which the
Company has guaranteed or for which the Company is directly responsible or
liable as obligor or guarantor), having an aggregate principal amount
outstanding of at least $25,000,000, whether such indebtedness now exists or
shall hereafter be created, which default shall have resulted in such
indebtedness becoming or being declared due and payable prior to the date on
which it would otherwise have become due and payable, without such indebtedness
having been discharged, or such acceleration having been rescinded or annulled,
within a period of 30 days after written notice to the Company as provided in
the Indenture; (f) certain events of bankruptcy, insolvency or reorganization,
or court appointment of a receiver, liquidator or trustee of the Company or any
Significant Subsidiary; and (g) any other event of default provided with respect
to a particular series of Debt Securities. The term "Significant Subsidiary" has
the meaning ascribed to such term in Regulation S-X promulgated under the
Securities Act.
 
     If an Event of Default under any Indenture with respect to Debt Securities
of any series at the time outstanding occurs and is continuing, then in every
such case the applicable Trustee or the holders of not less than 25% in
principal amount of the Debt Securities of that series will have the right to
declare the principal amount (or, if the Debt Securities of that series are
Original Issue Discount Securities or indexed securities, such portion of the
principal amount as may be specified in the terms thereof) of, and premium or
Make-Whole Amount, if any, on, all the Debt Securities of that series to be due
and payable immediately by written notice thereof to the Company (and to the
applicable Trustee if given by the holders). However, at any time after such a
declaration of acceleration with respect to Debt Securities of such series has
been made, but before a judgment or decree for payment of the money due has been
obtained by the applicable Trustee, the holders of not less than a majority in
principal amount of outstanding Debt Securities of such series may rescind and
annul such declaration and its consequences if (a) the Company shall have
deposited with the applicable Trustee all required payments of the principal of
(and premium or Make-Whole Amount, if any) and interest on the Debt Securities
of such series, plus certain fees, expenses, disbursements and advances of the
applicable Trustee and (b) all Events of Default, other than the non-payment of
accelerated principal (or specified portion thereof and the premium or
Make-Whole Amount, if any), with respect to Debt Securities of such series have
been cured or waived as provided in such Indenture. The Indentures will also
provide that the holders of not less than a majority in principal amount of the
outstanding Debt Securities of any series may waive any past default with
respect to such series and its consequences, except a default (i) in the payment
of the principal of (or premium or Make-Whole Amount, if any) or interest on any
Debt Security of such series or (ii) in respect of a covenant or provision
contained in the applicable Indenture that cannot be modified or amended without
the consent of the holder of each outstanding Debt Security affected thereby.
 
     The Indentures will require each Trustee to give notice to the holders of
Debt Securities within 90 days of a default under the applicable Indenture
unless such default shall have been cured or waived; provided, however, that
such Trustee may withhold notice to the holders of any series of Debt Securities
of any default with respect to such series (except a default in the payment of
the principal of (or premium or Make-Whole Amount, if any) or interest on any
Debt Security of such series or in the payment of any sinking fund
 
                                        9
<PAGE>   11
 
installment in respect of any Debt Security of such series) if specified
responsible officers of such Trustee consider such withholding to be in the
interest of such holders.
 
     The Indentures will provide that no holders of Debt Securities of any
series may institute any proceedings, judicial or otherwise, with respect to
such Indenture or for any remedy thereunder, except in the case of failure of
the applicable Trustee, for 60 days, to act after it has received a written
request to institute proceedings in respect of an Event of Default from the
holders of not less than 25% in principal amount of the outstanding Debt
Securities of such series, as well as an offer of indemnity reasonably
satisfactory to it. This provision will not prevent, however, any holder of Debt
Securities from instituting suit for the enforcement of payment of the principal
of (and premium or Make-Whole Amount, if any) and interest on such Debt
Securities at the respective due dates or redemption dates thereof.
 
     The Indentures will provide that, subject to provisions in each Indenture
relating to its duties in case of default, a Trustee will be under no obligation
to exercise any of its rights or powers under an Indenture at the request or
direction of any holders of any series of Debt Securities then outstanding under
such Indenture, unless such holders shall have offered to the Trustee thereunder
reasonable security or indemnity. The holders of not less than a majority in
principal amount of the outstanding Debt Securities of any series (or of all
Debt Securities then outstanding under an Indenture, as the case may be) shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the applicable Trustee, or of exercising any trust
or power conferred upon such Trustee. However, a Trustee may refuse to follow
any direction which is in conflict with any law or the applicable Indenture,
which may involve such Trustee in personal liability or which may be unduly
prejudicial to the holders of Debt Securities of such series not joining
therein.
 
     Within 120 days after the close of each fiscal year, the Company will be
required to deliver to each Trustee a certificate, signed by one of several
specified officers of the Company, stating whether or not such officer has
knowledge of any default under the applicable Indenture and, if so, specifying
each such default and the nature and status thereof.
 
MODIFICATION OF THE INDENTURES
 
     Modifications and amendments of an Indenture will be permitted to be made
only with the consent of the holders of not less than a majority in principal
amount of all outstanding Debt Securities issued under such Indenture affected
by such modification or amendment; provided, however, that no such modification
or amendment may, without the consent of the holder of each such Debt Security
affected thereby, (a) change the stated maturity of the principal of, or any
installment of interest (or premium or Make-Whole Amount, if any) on, any such
Debt Security; (b) reduce the principal amount of, or the rate or amount of
interest on, or any premium or Make-Whole Amount payable on redemption of, any
such Debt Security, or reduce the amount of principal of an Original Issue
Discount Security that would be due and payable upon declaration of acceleration
of the maturity thereof or would be provable in bankruptcy, or adversely affect
any right of repayment of the holder of any such Debt Security; (c) change the
place of payment, or the coin or currency, for payment of principal of, premium
or Make-Whole Amount, if any, or interest on any such Debt Security; (d) impair
the right to institute suit for the enforcement of any payment on or with
respect to any such Debt Security; (e) reduce the above-stated percentage of
outstanding Debt Securities of any series necessary to modify or amend the
applicable Indenture, to waive compliance with certain provisions thereof or
certain defaults and consequences thereunder or to reduce the quorum or voting
requirements set forth in the applicable Indenture; (f) change the currency or
currency unit in which any Debt Security or any premium or interest thereon is
payable; (g) in the case of the Subordinated Indenture, modify the subordination
provisions thereof in a manner adverse to the holders of Subordinated Debt
Securities of any series then outstanding; or (h) modify any of the foregoing
provisions or any of the provisions relating to the waiver of certain past
defaults or certain covenants, except to increase the required percentage to
effect such action or to provide that certain other provisions may not be
modified or waived without the consent of the holder of such Debt Security.
 
                                       10
<PAGE>   12
 
     The holders of a majority in aggregate principal amount of the outstanding
Debt Securities of each series may, on behalf of all holders of Debt Securities
of that series, waive, insofar as that series is concerned, compliance by the
Company with certain restrictive covenants of the applicable Indenture.
 
     Modifications and amendments of an Indenture will be permitted to be made
by the Company and the respective Trustee thereunder without the consent of any
holder of Debt Securities for any of the following purposes: (a) to evidence the
succession of another person to the Company as obligor under such Indenture; (b)
to add to the covenants of the Company for the benefit of the holders of all or
any series of Debt Securities or to surrender any right or power conferred upon
the Company in such Indenture; (c) to add events of default for the benefit of
the holders of all or any series of Debt Securities; (d) to add or change any
provisions of an Indenture to facilitate the issuance of, or to liberalize
certain terms of, Debt Securities in bearer form, or to permit or facilitate the
issuance of Debt Securities in uncertificated form, provided that such action
shall not adversely affect the interests of the holders of the Debt Securities
of any series in any material respect; (e) to change or eliminate any provisions
of an Indenture, provided that any such change or elimination shall become
effective only when there are no Debt Securities outstanding of any series
created prior thereto which are entitled to the benefit of such provision; (f)
to secure the Debt Securities; (g) to establish the form or terms of Debt
Securities of any series; (h) to provide for the acceptance of appointment by a
successor Trustee or facilitate the administration of the trusts under an
Indenture by more than one Trustee; (i) to cure any ambiguity, defect or
inconsistency in an Indenture, provided that such action shall not adversely
affect the interests of holders of Debt Securities of any series issued under
such Indenture; or (j) to supplement any of the provisions of an Indenture to
the extent necessary to permit or facilitate defeasance and discharge of any
series of such Debt Securities, provided that such action shall not adversely
affect the interests of the holders of the outstanding Debt Securities of any
series.
 
     The Indentures will provide that in determining whether the holders of the
requisite principal amount of outstanding Debt Securities of a series have given
any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of holders of Debt
Securities, (a) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon
declaration of acceleration of the maturity thereof, (b) the principal amount of
any Debt Security denominated in a foreign currency that shall be deemed
Outstanding shall be the U.S. dollar equivalent, determined on the issue date
for such Debt Security, of the principal amount (or, in the case of an Original
Issue Discount Security, the U.S. dollar equivalent on the issue date of such
Debt Security of the amount determined as provided in (a) above), (c) the
principal amount of an indexed security that shall be deemed outstanding shall
be the principal face amount of such indexed security at original issuance,
unless otherwise provided with respect to such indexed security pursuant such
Indenture, and (d) Debt Securities owned by the Company or any other obligor
upon the Debt Securities or any affiliate of the Company or of such other
obligor shall be disregarded.
 
     The Indentures will contain provisions for convening meetings of the
holders of Debt Securities of a series. A meeting will be permitted to be called
at any time by the applicable Trustee, and also, upon request, by the Company or
the holders of at least 25% in principal amount of the outstanding Debt
Securities of such series, in any such case upon notice given as provided in
such Indenture. Except for any consent that must be given by the holder of each
Debt Security affected by certain modifications and amendments of an Indenture,
any resolution presented at a meeting or adjourned meeting duly reconvened at
which a quorum is present may be adopted by the affirmative vote of the holders
of a majority in principal amount of the outstanding Debt Securities of that
series; provided, however, that, except as referred to above, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that may be made, given or taken by the holders of a
specified percentage, which is less than a majority, in principal amount of the
outstanding Debt Securities of a series may be adopted at a meeting or adjourned
meeting or adjourned meeting duly reconvened at which a quorum is present by the
affirmative vote of the holders of such specified percentage in principal amount
of the outstanding Debt Securities of that series. Any resolution passed or
decision taken at any meeting of holders of Debt Securities of any series duly
held in accordance with an Indenture will be binding on all holders of Debt
Securities of that series. The quorum at any meeting called to adopt a
resolution, and at any reconvened meeting, will be persons holding or
representing a majority in
 
                                       11
<PAGE>   13
 
principal amount of the outstanding Debt Securities of a series; provided,
however, that if any action is to be taken at such meeting with respect to a
consent or waiver which may be given by the holders of not less than a specified
percentage in principal amount of the outstanding Debt Securities of a series,
the persons holding or representing such specified percentage in principal
amount of the outstanding Debt Securities of such series will constitute a
quorum.
 
     Notwithstanding the foregoing provisions, the Indentures will provide that
if any action is to be taken at a meeting of holders of Debt Securities of any
series with respect to any request, demand, authorization, direction, notice,
consent, waiver and other action that such Indenture expressly provides may be
made, given or taken by the holders of a specified percentage in principal
amount of all outstanding Debt Securities affected thereby, or of the holders of
such series and one or more additional series: (a) there shall be no minimum
quorum requirement for such meeting and (b) the principal amount of the
outstanding Debt Securities of such series that vote in favor of such request,
demand, authorization, direction, notice, consent, waiver or other action shall
be taken into account in determining whether such request, demand,
authorization, direction, notice, consent, waiver or other action has been made,
given or taken under such Indenture.

     "Senior Indebtedness" means Indebtedness of the Company, whether
outstanding on the date of issue of any Subordinated Debt Securities or
thereafter created, incurred, assumed or guaranteed by the Company, other than
the following: (a) any Indebtedness as to which, in the instrument evidencing
such Indebtedness or pursuant to which such Indebtedness was issued, it is
expressly provided that such Indebtedness is subordinate in right of payment to
all indebtedness of the Company not expressly subordinated to such Indebtedness;
(b) any Indebtedness which by its terms refers explicitly to the Subordinated
Debt Securities and states that such Indebtedness shall not be senior, shall be
pari passu or shall be subordinated in right of payment to the Subordinated Debt
Securities; and (c) with respect to any series of Subordinated Debt Securities,
any Indebtedness of the Company evidenced by Subordinated Debt Securities of the
same or of another series. Notwithstanding anything to the contrary in the
foregoing, Senior Indebtedness shall not include: (x) Indebtedness of or amounts
owed by the Company for compensation to employees, or for goods, materials and
services purchased in the ordinary course of business or (y) Indebtedness of the
Company to a subsidiary of the Company.
 
SUBORDINATION
 
     Unless otherwise provided in the applicable Prospectus Supplement,
Subordinated Debt Securities will be subject to the following subordination
provisions.
 
                                       12
<PAGE>   14
 
     The payment of the principal of, interest on, or any other amounts due on,
the Subordinated Debt Securities will be subordinated in right of payment to the
prior payment in cash in full of all Senior Indebtedness of the Company. No
payment on account of the principal of, redemption of, interest on or any other
amounts due on the Subordinated Debt Securities and no redemption, purchase or
other acquisition of the Subordinated Debt Securities may be made, unless (a)
full payment in cash of amounts then due for principal, sinking funds, interest
(including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to the Company, whether or not a claim
for such post-petition interest is allowed in such proceeding), penalties,
reimbursement or indemnification amounts, fees and expenses, and of all other
amounts then due on all Senior Indebtedness shall have been made or duly
provided for pursuant to the terms of the instrument governing such Senior
Indebtedness, and (b) at the time of, or immediately after giving effect to, any
such payment, redemption, purchase or other acquisition, there shall not exist
under any Senior Indebtedness or any agreement pursuant to which any Senior
Indebtedness has been issued, any default which shall not have been cured or
waived and which shall have resulted in the full amount of such Senior
Indebtedness being declared due and payable and not rescinded. In addition, the
Subordinated Indenture provides that, if holders of any Senior Indebtedness
notify the Company and the Subordinated Trustee that a default has occurred
giving the holders of such Senior Indebtedness the right to accelerate the
maturity thereof, no payment on account of principal, sinking fund or other
redemption, interest or any other amounts due on the Subordinated Debt
Securities and no purchase, redemption or other acquisition of the Subordinated
Debt Securities will be made for the period (the "Payment Blockage Period")
commencing on the date such notice is received and ending on the earlier of (i)
the date on which such event of default shall have been cured or waived or (ii)
180 days from the date such notice is received. Notwithstanding the foregoing,
only one payment blockage notice with respect to the same event of default or
any other events of default existing and known to the person giving such notice
at the time of such notice on the same issue of Senior Indebtedness may be given
during any period of 360 consecutive days. No new Payment Blockage Period may be
commenced by the holders of Senior Indebtedness during any period of 360
consecutive days unless all events of default which triggered the preceding
Payment Blockage Period have been cured or waived. Upon any distribution of its
assets in connection with any dissolution, winding-up, liquidation or
reorganization of the Company, all Senior Indebtedness must be paid in full in
cash before the holders of the Subordinated Debt Securities are entitled to any
payments whatsoever.
 
     The Subordinated Indenture does not restrict the amount of Senior
Indebtedness or other indebtedness of the Company or any Subsidiary. As a result
of these subordination provisions, in the event of the Company's insolvency,
holders of the Subordinated Debt Securities may recover ratably less than
general creditors of the Company.
 
     If this Prospectus is being delivered in connection with a series of
Subordinated Debt Securities, the accompanying Prospectus Supplement or the
information incorporated herein by reference will set forth the approximate
amount of Senior Indebtedness outstanding as of the end of the Company's most
recent fiscal quarter.
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Company will be permitted, at its option, to discharge certain obligations to
holders of any series of Debt Securities issued under any Indenture that have
not already been delivered to the applicable Trustee for cancellation and that
either have become due and payable or will become due and payable within one
year (or scheduled for redemption within one year) by irrevocably depositing
with the applicable Trustee, in trust, funds in such currency or currencies,
currency unit or units or composite currency or currencies in which such Debt
Securities are payable in an amount sufficient to pay the entire indebtedness on
such Debt Securities in respect of principal (and premium or Make-Whole Amount,
if any) and interest to the date of such deposit (if such Debt Securities have
become due and payable) or to the stated maturity or redemption date, as the
case may be.
 
     The Indentures will provide that, unless otherwise indicated in the
applicable Prospectus Supplement, the Company may elect either (a) to defease
and be discharged from any and all obligations with respect to such Debt
Securities (except for the obligations to register the transfer or exchange of
such Debt Securities, to replace temporary or mutilated, destroyed, lost or
stolen Debt Securities, to maintain an office or agency in
 
                                       13
<PAGE>   15
 
respect of such Debt Securities, and to hold moneys for payment in trust)
("defeasance") or (b) to be released from certain obligations with respect to
such Debt Securities under the applicable Indenture (including the restrictions
described under "-- Certain Covenants") or, if provided in the applicable
Prospectus Supplement, its obligations with respect to any other covenant, and
any omission to comply with such obligations shall not constitute an Event of
Default with respect to such Debt Securities ("covenant defeasance"), in either
case upon the irrevocable deposit by the Company with the applicable Trustee, in
trust, of an amount, in such currency or currencies, currency unit or units or
composite currency or currencies in which such Debt Securities are payable at
stated maturity, or Government Obligations (as defined below), or both,
applicable to such Debt Securities, which through the scheduled payment of
principal and interest in accordance with their terms will provide money in an
amount sufficient to pay the principal of (and premium or Make-Whole Amount, if
any) and interest on such Debt Securities, and any mandatory sinking fund or
analogous payments thereon, on the scheduled due dates therefor.
 
     Such a trust will only be permitted to be established if, among other
things, the Company has delivered to the applicable Trustee an opinion of
counsel (as specified in the applicable Indenture) to the effect that the
holders of such Debt Securities will not recognize income, gain or loss for U.S.
federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to U.S. federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance or covenant defeasance had not occurred, and such opinion of counsel,
in the case of defeasance, will be required to refer to and be based upon a
ruling received from or published by the Internal Revenue Service or a change in
applicable United States federal income tax law occurring after the date of the
Indenture. In the event of such defeasance, the holders of such Debt Securities
would thereafter be able to look only to such trust fund for payment of
principal (and premium or Make-Whole Amount, if any) and interest.
 
     "Government Obligations" means securities that are (a) direct obligations
of the United States of America or the government which issued the foreign
currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged or (b) obligations 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 the Debt Securities of such series 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, are
not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank or trust company as custodian with
respect to any such Government Obligation or a specific payment of interest on
or principal of any such Government Obligation held by such custodian for the
account of the holder of a depository receipt, 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 depository receipt from any amount received by the
custodian in respect of the Government Obligation or the specific payment of
interest on or principal of the Government Obligation evidenced by such
depository receipt.
 
     Unless otherwise provided in the applicable Prospectus Supplement, if after
the Company has deposited funds and/or Government Obligations to effect
defeasance or covenant defeasance with respect to Debt Securities of any series,
(a) the holder of a Debt Security of such series is entitled to, and does, elect
pursuant to the applicable Indenture or the terms of such Debt Security to
receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security, or
(b) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security will be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of
(and premium or Make-Whole Amount, if any) and interest on such Debt Security as
they become due out of the proceeds yielded by converting the amount so
deposited in respect of such Debt Security into the currency, currency unit or
composite currency in which such Debt Security becomes payable as a result of
such election or such cessation of usage based on the applicable market exchange
rate. "Conversion Event" means the cessation of use of (i) a currency, currency
unit or composite currency both by the government of the country which issued
such currency and for the settlement of transactions by a central bank or other
public institutions of or within the international banking community, (ii) the
ECU both within the European Monetary System and for the settlement of
transactions by public institutions of or within the European Communities or
(iii)
 
                                       14
<PAGE>   16
 
any currency unit or composite currency other than the ECU for the purposes for
which it was established. Unless otherwise provided in the applicable Prospectus
Supplement, all payments of principal of (and premium or Make-Whole Amount, if
any) and interest on any Debt Security that is payable in a foreign currency
that ceases to be used by its government of issuance shall be made in U.S.
dollars.
 
     In the event the Company effects covenant defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event of Default described
in clause (d) under "-- Events of Default, Notice and Waiver" with respect to
specified sections of an Indenture (which sections would no longer be applicable
to such Debt Securities) or described in clause (g) under "-- Events of Default,
Notice and Waiver" with respect to any other covenant as to which there has been
covenant defeasance, the amount in such currency, currency unit or composite
currency in which such Debt Securities are payable, and Government Obligations
on deposit with the applicable Trustee, will be sufficient to pay amounts due on
such Debt Securities at the time of their stated maturity but may not be
sufficient to pay amounts due on such Debt Securities at the time of the
acceleration resulting from such Event of Default. However, the Company would
remain liable to make payment of such amounts due at the time of acceleration.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which the Debt Securities are
convertible into Common Stock or Preferred Stock will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include
whether such Debt Securities are convertible into shares of Common Stock or
Preferred Stock, the conversion price (or manner of calculation thereof), the
conversion period, provisions as to whether conversion will be at the option of
the holders or the Company, the events requiring an adjustment of the conversion
price and provisions affecting conversion in the event of the redemption of such
Debt Securities and any restrictions on conversion, including restrictions
directed at maintaining the Company's REIT status.
 
BOOK-ENTRY SYSTEM
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities ("Global Securities") that will be
deposited with, or on behalf of, a depository (the "Depository") identified in
the Prospectus Supplement relating to such series. Global Securities, if any,
issued in the United States are expected to be deposited with The Depository
Trust Company ("DTC"), as Depository. Global Securities may be issued in fully
registered form and may be issued in either temporary or permanent form. Unless
and until it is exchanged in whole or in part for the individual Debt Securities
represented thereby, a Global Security may not be transferred except as a whole
by the Depository for such Global Security to a nominee of such Depository or by
a nominee of such Depository to such Depository or another nominee of such
Depository or by such Depository or any nominee of such Depositor to a successor
Depository or any nominee of such successor.
 
     The specific terms of the depository arrangement with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. The Company expects that unless otherwise indicated in the
applicable Prospectus Supplement, the following provisions will apply to
depository arrangements.
 
     Upon the issuance of a Global Security, the Depository for such Global
Security or its nominee will credit on its book-entry registration and transfer
system the respective principal amounts of the individual Debt Securities
represented by such Global Security to the accounts of persons that have
accounts with such Depository ("Participants"). Such accounts shall be
designated by the underwriters, dealers or agents with respect to such Debt
Securities or by the Company if such Debt Securities are offered directly by the
Company. Ownership of beneficial interests in such Global Security will be
limited to Participants or persons that may hold interests through Participants.
 
                                       15
<PAGE>   17
 
     The Company expects that, pursuant to procedures established by DTC,
ownership of beneficial interests in any Global Security with respect to which
DTC is the Depository will be shown on, and the transfer of that ownership will
be effected only through, records maintained by DTC or its nominee (with respect
to beneficial interests of Participants) and records of Participants (with
respect to beneficial interests of persons who hold through Participants).
Neither the Company nor the Trustee will have any responsibility or liability
for any aspect of the records of DTC or for maintaining, supervising or
reviewing any records of DTC or any of its Participants relating to beneficial
ownership interests in the Debt Securities. The laws of some states require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and laws may impair the ability to own, pledge or
transfer beneficial interest in a Global Security.
 
     So long as the Depository for a Global Security or its nominee is the
registered owner of such Global Security, such Depository or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
applicable Indenture. Except as described below or in the applicable Prospectus
Supplement, owners of beneficial interest in a Global Security will not be
entitled to have any of the individual Debt Securities represented by such
Global Security registered in their names, will not receive or be entitled to
receive physical delivery of any such Debt Securities in definitive form and
will not be considered the owners or holders thereof under the applicable
Indenture. Beneficial owners of Debt Securities evidenced by a Global Security
will not be considered the owners or holders thereof under the applicable
Indenture for any purpose, including with respect to the giving of any
direction, instructions or approvals to the Trustee thereunder. Accordingly,
each person owning a beneficial interest in a Global Security with respect to
which DTC is the Depository must rely on the procedures of DTC and, if such
person is not a Participant, on the procedures of the Participant through which
such person owns its interests, to exercise any rights of a holder under the
applicable Indenture. The Company understands that, under existing industry
practice, if it requests any action of holders or if an owner of a beneficial
interest in a Global Security desires to give or take any action which a holder
is entitled to give or take under the applicable Indenture, DTC would authorize
the Participants holding the relevant beneficial interest to give or take such
action, and such Participants would authorize beneficial owners through such
Participants to give or take such actions or would otherwise act upon the
instructions of beneficial owners holding through them.
 
     Payments of principal of, any premium or Make-Whole Amount and any interest
on individual Debt Securities represented by a Global Security registered in the
name of a Depository or its nominee will be made to or at the direction of the
Depository or its nominee, as the case may be, as the registered owner of the
Global Security under the applicable Indenture. Under the terms of the
applicable Indenture, the Company and the Trustee may treat the persons in whose
name Debt Securities, including a Global Security, are registered as the owners
thereof for the purpose of receiving such payments. Consequently, neither the
Company nor the Trustee has or will have any responsibility or liability for the
payment of such amounts to beneficial owners of Debt Securities (including
principal, premium or Make-Whole Amount, if any, and interest). The Company
believes, however, that it is currently the policy of DTC to immediately credit
the accounts of relevant Participants with such payments, in amounts
proportionate to their respective holdings of beneficial interests in the
relevant Global Security as shown on the records of DTC or its nominee. The
Company also expects that payments by Participants to owners of beneficial
interests in such Global Security held through such Participants will be
governed by standing instructions and customary practices, as is the case with
securities held for the account of customers in bearer form or registered in
street name, and will be the responsibility of such Participants. Redemption
notices with respect to any Debt Securities represented by a Global Security
will be sent to the Depository or its nominee. If less than all of the Debt
Securities of any series are to be redeemed, the Company expects the Depository
to determine the amount of the interest of each Participant in such Debt
Securities to be redeemed to be determined by lot. None of the Company, the
Trustee, any Paying Agent or the Security Registrar for such Debt Securities
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests in the Global
Security for such Debt Securities or for maintaining any records with respect
thereto.
 
     Neither the Company nor the Trustee will be liable for any delay by the
holders of a Global Security or the Depository in identifying the beneficial
owners of Debt Securities and the Company and the Trustee may conclusively rely
on, and will be protected in relying on, instructions from the holder of a
Global Security or
 
                                       16
<PAGE>   18
 
the Depository for all purposes. The rules applicable to DTC and its
Participants are on file with the Securities and Exchange Commission.
 
     If a Depository for any Debt Securities is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days, the Company will issue individual Debt Securities
in exchange for the Global Security representing such Debt Securities. In
addition, the Company may at any time and in its sole discretion, subject to any
limitations described in the Prospectus Supplement relating to such Debt
Securities, determine not to have any of such Debt Securities represented by one
or more Global Securities and in such event will issue individual Debt
Securities in exchange for the Global Security or Securities representing such
Debt Securities. Individual Debt Securities so issued will be issued in
denominations of $1,000 and integral multiples thereof.
 
     The Debt Securities of a series may also be issued in whole or in part in
the form of one or more bearer global securities (a "Bearer Global Security")
that will be deposited with a depository, or with a nominee for such depository,
identified in the applicable Prospectus Supplement. Any such Bearer Global
Securities may be issued in temporary or permanent form. The specific terms and
procedures, including the specific terms of the depository arrangement, with
respect to any portion of a series of Debt Securities to be represented by one
or more Bearer Global Securities will be described in the applicable Prospectus
Supplement.
 
PAYMENT AND PAYING AGENTS
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium or Make-Whole Amount, if any) and interest
on any series of Debt Securities will be payable at the corporate trust office
of the Trustee, the address of which will be stated in the applicable Prospectus
Supplement; provided that, at the option of the Company, payment of interest may
be made by check mailed to the address of the person entitled thereto as it
appears in the applicable register for such Debt Securities or by wire transfer
of funds to such person at an account maintained within the United States.
 
     All moneys paid by the Company to a paying agent or a Trustee for the
payment of the principal of or any premium, Make-Whole Amount or interest on any
Debt Security which remain unclaimed at the end of two years after such
principal, premium, Make-Whole Amount or interest has become due and payable
will be repaid to the Company, and the holder of such Debt Security thereafter
may look only to the Company for payment thereof.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary identified in the applicable
Prospectus Supplement relating to such series. Global Securities may be issued
in either registered or bearer form and in either temporary or permanent form.
The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the applicable Prospectus Supplement
relating to such series.
 
                        DESCRIPTION OF PREFERRED STOCK
 
     The description of the Company's preferred stock, par value $.01 per share
("Preferred Stock"), set forth below does not purport to be complete and is
qualified in its entirety by reference to the Company's Amended and Restated
Articles of Incorporation, as amended by Articles Supplementary Establishing and
Fixing the Rights and Preferences of a Series of Shares of Preferred Stock
(Series A) and by Articles Supplementary Establishing and Fixing the Rights and
Preferences of a Series of Shares of Preferred Stock (Series B) (the "Articles
of Incorporation") and Amended and Restated Bylaws (the "Bylaws").
 
GENERAL
 
     Under the Articles of Incorporation, the Company has authority to issue 10
million shares of Preferred Stock, 3,300,000 shares of which were issued and
outstanding as of December 27, 1996. Shares of Preferred Stock may be issued
from time to time, in one or more series, as authorized by the Board of
Directors of the Company. Prior to issuance of shares of each series, the Board
of Directors is required by the Maryland General Corporation Law ("MGCL") and
the Company's Articles of Incorporation to fix for each series,
 
                                       17
<PAGE>   19
 
subject to the provisions of the Company's Articles of Incorporation regarding
excess stock, $.01 par value per share ("Excess Stock"), the terms, preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends or other distributions, qualifications and terms or conditions of
redemption, as are permitted by Maryland law. The Preferred Stock will, when
issued, be fully paid and nonassessable and will have no preemptive rights. The
Board of Directors could authorize the issuance of shares of Preferred Stock
with terms and conditions that could have the effect of discouraging a takeover
or other transaction that holders of Common Stock might believe to be in their
best interests or in which holders of some, or a majority, of the shares of
Common Stock might receive a premium for their shares over the then market price
of such shares of Common Stock.
 
TERMS
 
     The following description of the Preferred Stock sets forth certain general
terms and provisions of the Preferred Stock to which any Prospectus Supplement
may relate. The statements below describing the Preferred Stock are in all
respects subject to and qualified in their entirety by reference to the
applicable provisions of the Company's Articles of Incorporation and Bylaws and

     the affairs of the Company; and
 
          (14) Any limitations on direct or beneficial ownership and
     restrictions on transfer, in each case as may be appropriate to preserve
     the status of the Company as a REIT.
 
RANK
 
     Unless otherwise specified in the Prospectus Supplement, the Preferred
Stock will, with respect to dividend rights and rights upon liquidation,
dissolution or winding up of the Company, rank (i) senior to all classes or
series of Common Stock of the Company, and to all equity securities ranking
junior to such Preferred Stock with respect to dividend rights or rights upon
liquidation, dissolution or winding up of the Company; (ii) on a parity with all
equity securities issued by the Company the terms of which specifically provide
that such equity securities rank on a parity with the Preferred Stock with
respect to dividend rights or
 
                                       18
<PAGE>   20
 
rights upon liquidation, dissolution or winding up of the Company; and (iii)
junior to all equity securities issued by the Company the terms of which
specifically provide that such equity securities rank senior to the Preferred
Stock with respect to dividend rights or rights upon liquidation, dissolution or
winding up of the Company. The term "equity securities" does not include
convertible debt securities.
 
DIVIDENDS
 
     Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of assets
of the Company legally available for payment, cash dividends at such rates and
on such dates as will be set forth in the applicable Prospectus Supplement. Each
such dividend shall be payable to holders of record as they appear on the share
transfer books of the Company on such record dates as shall be fixed by the
Board of Directors of the Company.
 
     Dividends on any series of the Preferred Stock may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board of Directors of the Company fails
to declare a dividend payable on a dividend payment date on any series of the
Preferred Stock for which dividends are non-cumulative, then the holders of such
series of the Preferred Stock will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and the
Company will have no obligation to pay the dividend accrued for such period,
whether or not dividends on such series are declared payable on any future
dividend payment date.
 
     If Preferred Stock of any series is outstanding, no dividends will be
declared or paid or set apart for payment on any capital stock of the Company of
any other series ranking, as to dividends, on a parity with or junior to the
Preferred Stock of such series for any period unless (i) if such series of
Preferred Stock has a cumulative dividend, full cumulative dividends have been
or contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof is set apart for such payment on the Preferred Stock of such
series for all past dividend periods and the then current dividend period or
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends for the then current dividend period have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for such payment on the Preferred Stock of such series. When
dividends are not paid in full (or a sum sufficient for such full payment is not
so set apart) upon Preferred Stock of any series and the shares of any other
series of Preferred Stock ranking on a parity as to dividends with the Preferred
Stock of such series, all dividends declared upon Preferred Stock of such series
and any other series of Preferred Stock ranking on a parity as to dividends with
such Preferred Stock shall be declared pro rata so that the amount of dividends
declared per share of Preferred Stock of such series and such other series of
Preferred Stock shall in all cases bear to each other the same ratio that
accrued dividends per share on the Preferred Stock of such series (which shall
not include any accumulation in respect of unpaid dividends for prior dividend
periods if such Preferred Stock does not have a cumulative dividend) and such
other series of Preferred Stock bear to each other. No interest, or sum of money
in lieu of interest, shall be payable in respect of any dividend payment or
payments on Preferred Stock of such series which may be in arrears.
 
     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for payment for all past dividend periods and the then current
dividend period, and (ii) if such series of Preferred Stock does not have a
cumulative dividend, full dividends on the Preferred Stock of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof is set apart for payment for the then current dividend
period, no dividends (other than in shares of Common Stock or other shares of
capital stock ranking junior to the Preferred Stock of such series as to
dividends and upon liquidation) shall be declared or paid or set aside for
payment nor shall any other distribution be declared or made upon the Common
Stock, or any other capital stock of the Company ranking junior to or on a
parity with the Preferred Stock of such series as to dividends or upon
liquidation, nor shall any shares of Common Stock, or any other shares of
capital stock of the Company ranking junior to or on a parity with the Preferred
Stock of such series as to dividends or upon liquidation be redeemed, purchased
or otherwise acquired for any consideration (or any moneys be paid to or made
available for a sinking fund for the redemption of any such
 
                                       19
<PAGE>   21
 
shares) by the Company (except by conversion into or exchange for other capital
stock of the Company ranking junior to the Preferred Stock of such series as to
dividends and upon liquidation).
 
     Any dividend payment made on shares of a series of Preferred Stock shall
first be credited against the earliest accrued but unpaid dividend due with
respect to shares of such series which remains payable.
 
REDEMPTION
 
     If so provided in the applicable Prospectus Supplement, the Preferred Stock
will be subject to mandatory redemption or redemption at the option of the
Company, as a whole or in part, in each case upon the terms, at the times and at
the redemption prices set forth in such Prospectus Supplement.
 
     The Prospectus Supplement relating to a series of Preferred Stock that is
subject to mandatory redemption will specify the number of shares of such
Preferred Stock that shall be redeemed by the Company in each year commencing
after a date to be specified, at a redemption price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon (which
shall not, if such Preferred Stock does not have a cumulative dividend, include
any accumulation in respect of unpaid dividends for prior dividend periods) to
the date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Stock of any series is payable only from the net
proceeds of the issuance of shares of capital stock of the Company, the terms of
such Preferred Stock may provide that, if no such shares of capital stock shall
have been issued or to the extent the net proceeds from any issuance are
insufficient to pay in full the aggregate redemption price then due, such
Preferred Stock shall automatically and mandatorily be converted into the
applicable shares of capital stock of the Company pursuant to conversion
provisions specified in the applicable Prospectus Supplement.
 
     Notwithstanding the foregoing, unless (i) if a series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all shares of such
series of Preferred Stock shall have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for all past dividend periods and the then current dividend period, and
(ii) if a series of Preferred Stock does not have a cumulative dividend, full
dividends on all shares of the Preferred Stock of such series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend period, no
shares of such series of Preferred Stock shall be redeemed unless all
outstanding shares of Preferred Stock of such series are simultaneously
redeemed; provided, however, that the foregoing shall not prevent the purchase
or acquisition of Preferred Stock of such series to preserve the REIT status of
the Company or pursuant to a purchase or exchange offer made on the same terms
to holders of all outstanding shares of Preferred Stock of such series. In
addition, unless (i) if such series of Preferred Stock has a cumulative
dividend, full cumulative dividends on all outstanding shares of such series of
Preferred Stock have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for payment for all past
dividend periods and the then current dividend period, and (ii) if such series
of Preferred Stock does not have a cumulative dividend, full dividends on the
Preferred stock of such series have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for the then current dividend period, the Company shall not purchase or
otherwise acquire directly or indirectly any shares of Preferred Stock of such
series (except by conversion into or exchange for capital shares of the Company
ranking junior to the Preferred Stock of such series as to dividends and upon
liquidation); provided, however, that the foregoing shall not prevent the
purchase or acquisition of shares of Preferred Stock of such series to preserve
the REIT status of the Company or pursuant to a purchase or exchange offer made
on the same terms to holders of all outstanding shares of Preferred Stock of
such series.
 
     If fewer than all of the outstanding shares of Preferred Stock of any
series are to be redeemed, the number of shares to be redeemed will be
determined by the Company and such shares may be redeemed pro rata from the
holders of record of such shares in proportion to the number of such shares held
or for which redemption is requested by such holder (with adjustments to avoid
redemption of fractional shares) or by any other equitable manner determined by
the Company.
 
                                       20
<PAGE>   22
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred Stock of
any series to be redeemed at the address shown on the stock transfer books of
the Company. Each notice shall state: (i) the redemption date; (ii) the number
of shares and series of the Preferred Stock to be redeemed; (iii) the redemption
price; (iv) the place or places where certificates for such Preferred Stock are
to be surrendered for payment of the redemption price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date; and (vi) the
date upon which the holder's conversion rights, if any, as to such shares shall
terminate. If fewer than all the shares of Preferred Stock of any series are to
be redeemed, the notice mailed to each such holder thereof shall also specify
the number of shares of Preferred Stock to be redeemed from each such holder. If
notice of redemption of any Preferred Stock has been given and if the funds
necessary for such redemption have been set aside by the Company in trust for
the benefit of the holders of any Preferred Stock so called for redemption, then
from and after the redemption date dividends will cease to accrue on such
Preferred Stock, and all rights of the holders of such shares will terminate,
except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, then, before any distribution or payment shall be
made to the holders of any Common Stock or any other class or series of capital
stock of the Company ranking junior to the Preferred Stock in the distribution
of assets upon any liquidation, dissolution or winding up of the Company, the
holders of each series of Preferred Stock shall be entitled to receive out of
assets of the Company legally available for distribution to stockholders,
liquidating distributions in the amount of the liquidation preference per share,
if any, set forth in the applicable Prospectus Supplement, plus an amount equal
to all dividends accrued and unpaid thereon (which shall not include any
accumulation in respect of unpaid noncumulative dividends for prior dividend
periods). After payment of the full amount of the liquidating distributions to
which they are entitled, the holders of Preferred Stock will have no right or
claim to any of the remaining assets of the Company. In the event that, upon any
such voluntary or involuntary liquidation, dissolution or winding up, the
available assets of the Company are insufficient to pay the amount of the
liquidating distributions on all outstanding shares of Preferred Stock and the
corresponding amounts payable on all shares of other classes or series of
capital stock of the Company ranking on a parity with the Preferred Stock in the
distribution of assets, then the holders of the Preferred Stock and all other
such classes or series of capital stock shall share ratably in any such
distribution of assets in proportion to the full liquidating distributions to
which they would otherwise be respectively entitled.
 
     If liquidating distributions shall have been made in full to all holders of
Preferred Stock, the remaining assets of the Company shall be distributed among
the holders of any other classes or series of capital stock ranking junior to
the Preferred Stock upon liquidation, dissolution or winding up, according to
their respective rights and preferences and in each case according to their
respective number of shares. For such purposes, the consolidation or merger of
the Company with or into any other corporation, trust or entity, or the sale,
lease or conveyance of all or substantially all of the property or business of
the Company, shall not be deemed to constitute a liquidation, dissolution or
winding up of the Company.
 
VOTING RIGHTS
 
     Holders of the Preferred Stock will not have any voting rights, except as
set forth below or as otherwise from time to time required by law or as
indicated in the applicable Prospectus Supplement.
 
     Unless provided otherwise for any series of Preferred Stock, so long as any
shares of Preferred Stock of a series remain outstanding, the Company will not,
without the affirmative vote or consent of the holders of at least two-thirds of
the shares of such series of Preferred Stock outstanding at the time, given in
person or by proxy, either in writing or at a meeting (such series voting
separately as a class), (i) authorize or create, or increase the authorized or
issued amount of, any class or series of capital stock ranking prior to such
series of Preferred Stock with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up or reclassify
any authorized capital stock of the Company into such shares, or create,
authorize or issue any obligation or security convertible into or evidencing the
right to purchase any such shares; or (ii) amend, alter or repeal the provisions
of the Company's Articles of Incorporation or the Designating Amendment for such
series of Preferred Stock, whether by merger, consolidation or otherwise (an
"Event"),
 
                                       21
<PAGE>   23
 
so as to materially and adversely affect any right, preference, privilege or
voting power of such series of Preferred Stock or the holders thereof; provided,
however, with respect to the occurrence of any of the Events set forth in (ii)
above, so long as the Preferred Stock remains outstanding with the terms thereof
materially unchanged, taking into account that upon the occurrence of an Event
the Company may not be the surviving entity, the occurrence of any such Event
shall not be deemed to materially and adversely affect such rights, preferences,
privileges or voting power of holders of Preferred Stock, and provided further
that (x) any increase in the amount of the authorized Preferred Stock or the
creation or issuance of any other series of Preferred Stock, or (y) any increase
in the amount of authorized shares of such series or any other series of
Preferred Stock, in each case ranking on a parity with or junior to the
Preferred Stock of such series with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up, shall not be
deemed to materially and adversely affect such rights, preferences, privileges
or voting powers.
 
     The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall
be effected, all outstanding shares of such series of Preferred Stock shall have
been redeemed or called for redemption and sufficient funds shall have been
deposited in trust to effect such redemption.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which any series of Preferred Stock
is convertible into Common Stock will be set forth in the applicable Prospectus
Supplement relating thereto. Such terms will include the number of shares of
Common Stock into which the shares of Preferred Stock are convertible, the
conversion price (or manner of calculation thereof), the conversion period,
provisions as to whether conversion will be at the option of the holders of the
Preferred Stock or the Company, the events requiring an adjustment of the
conversion price and provisions affecting conversion in the event of the
redemption of such series of Preferred Stock.
 
RESTRICTIONS ON OWNERSHIP
 
     For the Company to qualify as a REIT under the Internal Revenue Code of
1986, as amended (the "Code"), not more than 50% in value of its outstanding
capital stock may be owned, directly or indirectly, by five or fewer individuals
(as defined in the Code to include certain entities) during the last half of a
taxable year. To assist the Company in meeting this requirement, the Company may
take certain actions to limit the beneficial ownership, directly or indirectly,
by a single person of the Company's outstanding equity securities, including any
Preferred Stock of the Company. Therefore, the Designating Amendment for each
series of Preferred Stock may contain provisions restricting the ownership and
transfer of the Preferred Stock. The applicable Prospectus Supplement will
specify any additional ownership limitation relating to a series of Preferred
Stock. See "Restrictions on Transfers of Capital Stock."
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Preferred Stock will be set forth
in the applicable Prospectus Supplement.
 
                          DESCRIPTION OF COMMON STOCK
 
     The description of the Company's Common Stock set forth below does not
purport to be complete and is qualified in its entirety by reference to the
Company's Articles of Incorporation and Bylaws.
 
GENERAL
 
     Under the Articles of Incorporation, the Company has authority to issue 40
million shares of Common Stock, par value $.01 per share. Under Maryland law,
stockholders generally are not responsible for the corporation's debts or
obligations. At December 27, 1996, the Company had outstanding 13,966,667 shares
of Common Stock.
 
TERMS
 
     Subject to the preferential rights of any other shares or series of stock
and to the provisions of the Company's Articles of Incorporation regarding
Excess Stock, holders of shares of Common Stock will be
 
                                       22
<PAGE>   24
 
entitled to receive dividends on shares of Common Stock if, as and when
authorized and declared by the Board of Directors of the Company out of assets
legally available therefor and to share ratably in the assets of the Company
legally available for distribution to its stockholders in the event of its
liquidation, dissolution or winding-up after payment of, or adequate provision
for, all known debts and liabilities of the Company.
 
     Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, each outstanding share of Common Stock entitles the
holder to one vote on all matters submitted to a vote of stockholders, including
the election of Directors and, except as otherwise required by law or except as
provided with respect to any other class or series of stock, the holders of
Common Stock will possess the exclusive voting power. There is no cumulative
voting in the election of Directors, which means that the holders of a majority
of the outstanding shares of Common Stock can elect all of the Directors then
standing for election, and the holders of the remaining shares of Common Stock
will not be able to elect any Directors.
 
     Holders of Common Stock have no conversion, sinking fund or redemption
rights, or preemptive rights to subscribe for any securities of the Company.
 
     The Company intends to furnish its stockholders with annual reports
containing audited consolidated financial statements and an opinion thereon
expressed by an independent public accounting firm and quarterly reports for the
first three quarters of each fiscal year containing unaudited financial
information.
 
     Subject to the provisions of the Company's Articles of Incorporation
regarding Excess Stock, all shares of Common Stock will have equal dividend,
distribution, liquidation and other rights, and will have no preference,
appraisal or exchange rights.
 
     Pursuant to the MGCL, a corporation generally cannot dissolve, amend its
Articles of Incorporation, merge, sell all or substantially all of its assets,
engage in a share exchange or engage in similar transactions outside the
ordinary course of business unless approved by the affirmative vote of
stockholders holding at least two-thirds of the shares entitled to vote on the
matter unless a lesser percentage (but not less than a majority of all of the
votes to be cast on the matter) is set forth in the corporation's Articles of
Incorporation. The Company's Articles of Incorporation do not provide for a
lesser percentage in such situations.
 
RESTRICTIONS ON OWNERSHIP
 
     For the Company to qualify as a REIT under the Code, not more than 50% in
value of its outstanding capital stock may be owned, directly or indirectly, by
five or fewer individuals (as defined in the Code to include certain entities)
during the last half of a taxable year. To assist the Company in meeting this
requirement, the Company may take certain actions to limit the beneficial
ownership, directly or indirectly, by a single person of the Company's
outstanding equity securities. See "Restrictions on Transfers of Capital Stock."
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Common Stock will be set forth in
the applicable Prospectus Supplement.
 
                   RESTRICTIONS ON TRANSFERS OF CAPITAL STOCK
 
     For the Company to qualify as a REIT under the Code, among other things,
not more than 50% in value of its outstanding capital stock may be owned,
directly or indirectly, by five or fewer individuals (as defined in the Code to
include certain entities) during the last half of a taxable year, and such
capital stock must be beneficially owned by 100 or more persons during at least
335 days of a taxable year of 12 months or during a proportionate part of a
shorter taxable year (in each case, other than the first such year). To ensure
that the Company remains a qualified REIT, the Articles of Incorporation,
subject to certain exceptions, provide that no holder may own, or be deemed to
own by virtue of the attribution provisions of the Code, more than 9.3% (the
"Ownership Limit") of the Company's capital stock. The Board of Directors may
waive the Ownership Limit if evidence satisfactory to the Board of Directors and
the Company's tax counsel is presented that the changes in ownership will not
then or in the future jeopardize the Company's status as a REIT. Any transfer of
capital stock or any security convertible into capital stock that would create a
direct or indirect ownership of capital stock in excess of the Ownership Limit
or that would result in the disqualification of the Company as a
 
                                       23
<PAGE>   25
 
REIT, including any transfer that results in the capital stock being owned by
fewer than 100 persons or results in the Company being "closely held" within the
meaning of Section 856(h) of the Code, shall be null and void, and the intended
transferee will acquire no rights to the capital stock. The foregoing
restrictions on transferability and ownership will not apply if the Board of
Directors determines that it is no longer in the best interests of the Company
to attempt to qualify, or to continue to qualify, as a REIT.
 
     Capital stock owned, or deemed to be owned, or transferred to a stockholder
in excess of the Ownership Limit will automatically be exchanged for shares of
Excess Stock that will be transferred, by operation of law, to the Company as
trustee of a trust for the exclusive benefit of the transferees to whom such
capital stock may be ultimately transferred without violating the Ownership
Limit. While the Excess Stock is held in trust, it will not be entitled to vote,
it will not be considered for purposes of any stockholder vote or the
determination of a quorum for such vote and, except upon liquidation, it will
not be entitled to participate in dividends or other distributions. Any dividend
or distribution paid to a proposed transferee of Excess Stock prior to the
discovery by the Company that capital stock has been transferred in violation of
the provisions of the Company's Articles of Incorporation shall be repaid to the
Company upon demand. The Excess Stock is not treasury stock, but rather
constitutes a separate class of issued and outstanding stock of the Company. The
original transferee-stockholder may, at any time the Excess Stock is held by the
Company in trust, transfer the interest in the trust representing the Excess
Stock to any individual whose ownership of the capital stock exchanged into such
Excess Stock would be permitted under the Ownership Limit, at a price not in
excess of the price paid by the original transferee-stockholder for the capital
stock that was exchanged in Excess Stock. Immediately upon the transfer to the
permitted transferee, the Excess Stock will automatically be exchanged for
capital stock of the class from which it was converted. If the foregoing
transfer restrictions are determined to be void or invalid by virtue of any
legal decision, statute, rule or regulation, then the intended transferee of any
Excess Stock may be deemed, at the option of the Company, to have acted as an
agent on behalf of the Company in acquiring the Excess Stock and to hold the
Excess Stock on behalf of the Company.
 
     In addition to the foregoing transfer restrictions, the Company will have
the right, for a period of 90 days during the time any Excess Stock is held by
the Company in trust, to purchase all or any portion of the Excess Stock from
the original transferee-stockholder for the lesser of the price paid for the
capital stock by the original transferee-stockholder or the market price (as
determined in the manner set forth in the Articles of Incorporation) of the
capital stock on the date the Company exercises its option to purchase. The
90-day period begins on the date on which the Company receives written notice of
the transfer or other event resulting in the exchange of capital stock for
Excess Stock.
 
     Each stockholder shall upon demand be required to disclose to the Company
in writing any information with respect to the direct, indirect and constructive
ownership of beneficial interests as the Board of Directors deems necessary to
comply with the provisions of the Code applicable to REITs, to comply with the
requirements of any taxing authority or governmental agency or to determine any
such compliance.
 
     This ownership limitation may have the effect of precluding acquisition of
control of the Company unless the Board of Directors determines that maintenance
of REIT status is no longer in the best interests of the Company.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
     The Company believes it has operated, and the Company intends to continue
to operate, in such manner as to qualify as a REIT under the Code, but no
assurance can be given that it will at all times so qualify.
 
     The provisions of the Code pertaining to REITs are highly technical and
complex. The following is a brief and general summary of certain provisions that
currently govern the federal income tax treatment of the Company and its
stockholders. For the particular provisions that govern the federal income tax
treatment of the Company and its stockholders, reference is made to Sections 856
through 860 of the Code and the regulations thereunder. The following summary is
qualified in its entirety by such reference.
 
     Under the Code, if certain requirements are met in a taxable year, a REIT
generally will not be subject to federal income tax with respect to income that
it distributes to its stockholders. If the Company fails to qualify during any
taxable year as a REIT, unless certain relief provisions are available, it will
be subject to tax
 
                                       24
<PAGE>   26
 
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates, which could have a material adverse effect upon its
stockholders.
 
     In any year in which the Company qualifies to be taxed as a REIT,
distributions made to its stockholders out of current or accumulated earnings
and profits will be taxed to stockholders as ordinary income except that
distributions of net capital gains designated by the Company as capital gain
dividends will be taxed as long-term capital gain income to the stockholders. To
the extent that distributions exceed current or accumulated earnings and
profits, they will constitute a return of capital, rather than dividend or
capital gain income, and will reduce the basis for the stockholder's Securities
with respect to which the distribution is paid or, to the extent that they
exceed such basis, will be taxed in the same manner as gain from the sale of
those Securities.
 
     Investors are urged to consult their own tax advisors with respect to the
appropriateness of an investment in the Securities offered hereby and with
respect to the tax consequences arising under federal law and the laws of any
state, municipality or other taxing jurisdiction, including tax consequences
resulting from such investor's own tax characteristics. In particular, foreign
investors should consult their own tax advisors concerning the tax consequences
of an investment in the Company, including the possibility of United States
income tax withholding on Company distributions.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell Securities to or through one or more underwriters or
dealers for public offering and sale by or through them, and may also sell
Securities directly to one or more institutional or other purchasers, through
agents or through any combination of these methods of sale. Any such
underwriter, dealer or agent involved in the offer and sale of Securities will
be named in the applicable Prospectus Supplement.
 
     Underwriters may offer and sell the Securities at a fixed price or prices,
which may be changed, or from time to time at market prices prevailing at the
time of sale, at prices related to such prevailing market prices or at
negotiated prices. The Company also may, from time to time, authorize
underwriters acting as the Company's agents to offer and sell the Securities
upon the terms and conditions as shall be set forth in any Prospectus
Supplement. In connection with the sale of Securities, underwriters may be
deemed to have received compensation from the Company in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of Securities for whom they may act as agent. 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.
 
     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of Securities, and any discounts, concessions or
commission allowed by underwriters to participating dealers, will be set forth
in an applicable Prospectus Supplement. Underwriters, dealers and agents
participating in the distribution of the Securities may be deemed to be
underwriters, 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. Underwriters, dealers and
agents may be entitled, under agreements with the Company, to indemnification
against and contribution toward certain civil liabilities, including liabilities
under the Securities Act, and to reimbursement by the Company for certain
expenses.
 
     Each series of Debt Securities or Preferred Stock will be a new issue with
no established trading market. The Company may elect to list any series of Debt
Securities or Preferred Stock on an exchange, but is not obligated to do so. It
is possible that one or more underwriters may make a market in a series of
Securities, but will not be obligated to do so and may discontinue any market
making at any time without notice. Therefore, no assurance can be given as to
the liquidity of, or the trading market for, the Securities.
 
     Underwriters, dealers and agents and their associates may engage in
transactions with, or perform services for, the Company in the ordinary course
of business.
 
     If so indicated in the applicable Prospectus Supplement, the Company will
authorize dealers or other persons acting as the Company's agents to solicit
offers by certain institutions to purchase Debt Securities from the Company at
the public offering price set forth in such Prospectus Supplement pursuant to
delayed
 
                                       25

delivery contracts ("Contracts") providing for payment and delivery on the date
or dates stated in such Prospectus Supplement. Each Contract will be for an
amount no less than, and the aggregate principal amounts of Debt Securities sold
pursuant to Contracts shall be not less nor more than, the respective amounts
stated in the applicable Prospectus Supplement. Institutions with whom
Contracts, when authorized, may be made include commercial and savings banks,
insurance companies, pension funds, investment companies, educational and
charitable institutions and other institutions, but will in all cases be subject
to the approval of the Company. Contracts will not be subject to any conditions
except (i) the purchase by an institution of the Debt Securities covered by its
Contracts shall not at the time of delivery be prohibited under the laws of any
jurisdiction in the United States to which such institution is subject, and (ii)
if Debt Securities are being sold to underwriters, the Company shall have sold
to such underwriters the total principal amount of the Debt Securities less the
principal amount thereof covered by the Contracts. If in conjunction with the
sale of Debt Securities to institutions under Contracts, Debt Securities are
also being sold to the public, the consummation of the sale under the Contracts
shall occur simultaneously with the consummation of the sale to the public. The
underwriters and such other agents will not have any responsibility in respect
of the validity or performance of such Contracts.
 
     In order to comply with the securities laws of certain states and other
jurisdictions, if applicable, the Securities offered hereby will be sold in such
jurisdictions only through registered or licensed brokers or dealers. In
addition, in certain states Securities may not be sold unless they have been
registered or qualified for sale in the applicable state or other jurisdiction
or an exemption from the registration or qualification requirement is available
and is complied with.
 
     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the Securities offered hereby may not
simultaneously engage in market making activities with respect to the Securities
for a period of two business days prior to the commencement of such
distribution.
 
                                 LEGAL MATTERS
 
     Certain legal matters, including the legality of the Securities, will be
passed upon for the Company by Goodwin, Procter & Hoar LLP, Boston,
Massachusetts.
 
                                    EXPERTS

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company's Articles of Incorporation and Bylaws, each as amended,
provide certain limitations on the liability of the Company's Directors and
officers for monetary damages to the Company. The Articles of Incorporation and
Bylaws obligate the Company to indemnify its Directors and officers, and permit
the Company to indemnify its employees and other agents, against certain
liabilities incurred in connection with their service in such capacities. The
Company has also entered into an indemnification agreement with each of the
members of the Board of Directors who are not officers of the Company (the
"Independent Directors"), pursuant to which the Company has agreed to indemnify
the Independent Directors against certain liabilities incurred in connection
with their service as Directors. These provisions and contracts could reduce the
legal remedies available to the Company and its stockholders against these
individuals.

ITEM 17.  UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes:
 
          (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 date 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 and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent 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 paragraphs (a)(1)(i) and (a)(1)(ii) herein do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the undersigned
registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement;
 
          (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; and
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, as amended each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the Registration
Statement 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.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer,
or controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the 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 of 1933, as amended and will be governed by the final
adjudication of such issue.
 
     (d) The undersigned registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act of 1939, as amended in
accordance with the rules and regulations prescribed by the Commission under
Section 305(b)(2) of the Act.

or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company and any agent of the Trustee or the Company, if made in
the manner provided in this Section. The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

            (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a

                                       13


<PAGE>   20


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

            (c) The ownership of Registered Securities shall be proved by the
Security Register. As to any matter relating to beneficial ownership interests
in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

            (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depository, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

            (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
PROVIDED that no such authorization, agreement or consent by the Holders on such
record date shall be deemed

                                       14


<PAGE>   21


effective unless it shall become effective pursuant to the provisions of this
Indenture not later than eleven months after the record date.

            (f) 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, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

      SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY. 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 Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at [__________________________]; or

                  (2) the Company by the Trustee or by any Holder shall be
      sufficient for every purpose hereunder (unless otherwise herein expressly
      provided) if in writing and mailed, first class postage prepaid, to the
      Company addressed to it at the address of its principal office specified
      in the first paragraph of this Indenture or at any other address
      previously furnished in writing to the Trustee by the Company, Attention:
      Chief Financial Officer (with a copy to the Company's General Counsel), or

                  (3) either the Trustee or the Company, by the other party,
      shall be sufficient for every purpose hereunder if given by facsimile
      transmission, receipt confirmed by telephone followed by an original copy
      delivered by guaranteed overnight courier; if to the Trustee at facsimile
      number [_________________]; and if to the Company at facsimile number
      (415) 391-6259.

      SECTION 106. NOTICE TO HOLDERS: WAIVER. Where this Indenture provides for
notice of any event to Holders of Registered Securities by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such 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 of Registered Securities 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 of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

                                       15


<PAGE>   22


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

      Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer Securities of any event, such notice shall be
sufficiently given if published in an Authorized Newspaper in The City of New
York and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, if any,
and not earlier than the earliest date, if any, prescribed for the giving of
such notice. Any such notice shall be deemed to have been given on the date of
such publication or, if published more than once, on the date of the first such
publication.

      If by reason of the suspension of publication of any Authorized Newspaper
or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

      Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.

      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.

      SECTION 107. COUNTERPARTS; EFFECT OF HEADINGS AND TABLE OF CONTENTS. This
Indenture 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 Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

      SECTION 108. SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Indenture by the Company shall bind its successors and assigns, whether so 
expressed or not.

      SECTION 109. SEVERABILITY CLAUSE. In case any provision in this Indenture

Securities or coupons, express or implied, shall give to any Person, other than

equitable right, remedy or claim under this Indenture.

      SECTION 112. LEGAL HOLIDAYS. In any case where any Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
exchange a Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security or coupon
other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu hereof), payment of interest or
principal (and premium or Make-Whole Amount, if any) or exchange of such
security need not be made at such Place of Payment on such date, but (except as
otherwise provided in the supplemental indenture with respect to such Security)
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, Redemption
Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or
Maturity, or on such last day for exchange, provided that no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

      SECTION 113. IMMUNITY OF STOCKHOLDERS, DIRECTORS, OFFICERS AND AGENTS OF
THE COMPANY. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
and as part of the consideration for the issue of the Securities.

limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

      SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee

Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Global Security shall be in writing but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

      The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security
together with written instructions (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 303.

      Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium or
Make-Whole Amount, if any, and interest on any Global Security in permanent
global form shall be made to the registered Holder thereof.

      Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat

                                       19

a permanent Global Security (i) in the case of a permanent Global Security in
registered form, the Holder of such permanent Global Security in registered
form, or (ii) in the case of a permanent Global Security in bearer form,

            the Indenture hereinafter referred to and is registered in the name
            of a Depository or a nominee of a Depository. This Security is
            exchangeable for Securities registered in the name of a person other
            than the Depository or its nominee only in the limited circumstances
            described in the Indenture, and may not be transferred except as a
            whole by the Depository to a nominee of the Depository or by a
            nominee of the Depository to the Depository or another nominee of
            the Depository or by the Depository or its nominee to a successor
            Depository or its nominee."

case of Registered Securities, as to denomination and except as may otherwise be

      SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

      Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

Indenture, the Company may deliver Securities of any series, together with any
coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company

in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and PROVIDED FURTHER

pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit B-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such Security or upon exchange of a
portion of a temporary Global Security shall be deemed to be delivery in
connection with its original issuance of such beneficial owner's interest in
such permanent Global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and canceled.

      If all the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such Securities and determining the terms of particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue. 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 TIA Section 315(a) through 315(d)) shall be fully protected in
relying upon,

            (i) an Opinion of Counsel stating that

                  (a) the form or forms of such Securities and any coupons 
            have been established in conformity with the provisions of this 
            Indenture;

                  (b) the terms of such Securities and any coupons have been
            established in conformity with the provisions of this Indenture; and

                  (c) such Securities, together with any coupons appertaining
            thereto, when completed by appropriate insertions and executed and
            delivered by the Company to the Trustee for authentication in
            accordance with this Indenture, authenticated and delivered by the
            Trustee in accordance with this Indenture and issued by the Company
            in the manner and subject to any conditions specified in such
            Opinion of Counsel, will constitute legal, valid and legally binding
            obligations of the Company, enforceable in accordance with their
            terms, subject to applicable bankruptcy, insolvency, fraudulent
            transfer, reorganization and other similar laws of general
            applicability relating to or affecting the enforcement of creditors'
            rights generally and to general equitable principles; and

            (ii) an Officers' Certificate stating that all conditions precedent
      provided for in this Indenture relating to the issuance of the Securities
      have been complied with and that, to the best of the knowledge of the
      signers of such certificate, that no Event of Default with respect to any
      of the Securities shall have occurred and be continuing.

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,
obligations 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 the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding

                                       25


<PAGE>   32


paragraph at the time of issuance of each Security of such series, but such
order, opinion and certificates, with appropriate modifications to cover such
future issuances, shall be delivered at or before the time of issuance of the
first Security of such series.

      Each Registered Security shall be dated the date of its authentication and
each Bearer Security shall be dated as of the date specified as contemplated by
Section 301.

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, 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.
                    ---------------------
     
      (a) Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities. In the case of Securities of any series, such temporary Securities
may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company 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 (accompanied by any
non-matured coupons appertaining thereto), the Company shall

                                       26


<PAGE>   33


execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series of authorized
denominations; PROVIDED, HOWEVER, that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security; and PROVIDED FURTHER
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
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.

      (b) Unless otherwise provided in or pursuant to a Board Resolution, the
following provisions of this Section 304(b) shall govern the exchange of
temporary Securities other than through the facilities of The Depository Trust
Company. If any such temporary Security is issued in global form, then such
temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository (the "Common
Depository"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; PROVIDED,
HOWEVER, that, unless otherwise specified in such temporary Global Security,
upon such presentation by the Common Depository, such temporary Global Security
is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary Global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL as to the portion of such temporary Global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and PROVIDED FURTHER that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary Global Security only
in compliance with the requirements of Section 303.


                                       27


<PAGE>   34


      Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary Global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and CEDEL on such
Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit B-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary Global Security with respect to which such certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners. Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial interest in a temporary Global Security will be
made unless and until such interest in such temporary Global Security shall have
been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and

                                       28


<PAGE>   35


CEDEL and not paid as herein provided shall be returned to the Trustee prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company.

      SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Company in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee, at its
Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided. In the event that the
Trustee shall cease to be Security Registrar, it shall have the right to examine
the Security Register at all reasonable times.

      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

      Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate, or in any
indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or

                                       29


<PAGE>   36


coupons in default, any such permitted exchange may be effected if the Bearer
Securities are accompanied by payment in funds acceptable to the Company in an
amount equal to the face amount of such missing coupon or coupons, or the
surrender of such missing coupon or coupons may be waived by the Company and the
Trustee if there is furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to any Paying Agent any such missing
coupon in respect of which such a payment shall have been made, such Holder
shall be entitled to receive the amount of such payment; PROVIDED, HOWEVER,
that, except as otherwise provided in Section 1002, interest represented by
coupons shall be payable only upon presentation and surrender of those coupons
at an office or agency located outside the United States. Notwithstanding the
foregoing, in case a Bearer Security of any series is surrendered at any such
office or agency in a permitted exchange for a Registered Security of the same
series and like tenor after the close of business at such office or agency on
(i) any Regular Record Date and before the opening of business at such office or
agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such Interest Payment Date or
proposed date for payment, as the case may be, and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such coupon when due in accordance with the provisions of this
Indenture. Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

      Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the
applicable Global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Company shall appoint a successor
depository with respect to such Global Security or Securities. If (x) a
successor depository for such Global Security or Securities is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such unwillingness, inability or ineligibility, (y) an Event of Default
has occurred and is continuing and the beneficial owners representing a majority
in principal amount of the applicable series of Securities represented by such
Global Security or Securities advise DTC to cease acting as depository for such
Global Security or Securities or (z) the Company, in its

                                       30


<PAGE>   37


sole discretion, determines at any time that all Outstanding Securities (but not
less than all) of any series issued or issuable in the form of one or more
Global Securities shall no longer be represented by such Global Security or
Securities, then the Company shall execute, and the Trustee shall authenticate
and deliver definitive Securities of like series, rank, tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of such Global Security or Securities. If any beneficial owner of an interest in
a permanent global Security is otherwise entitled to exchange such interest for
Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent Global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall execute, and the Trustee shall authenticate and deliver definitive
Securities in aggregate principal amount equal to the principal amount of such
beneficial owner's interest in such permanent Global Security. On or after the
earliest date on which such interests may be so exchanged, such permanent Global
Security shall be surrendered for exchange by DTC or such other depository as
shall be specified in the Company Order with respect thereto to the Trustee, as
the Company's agent for such purpose; PROVIDED, HOWEVER, that no such exchanges
may occur during a period beginning at the opening of business 15 days before
any selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected
for redemption; and PROVIDED FURTHER that no Bearer Security delivered in
exchange for a portion of a permanent Global Security shall be mailed or
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent Global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent Global Security is payable in accordance with the provisions
of this Indenture.

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

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

                                       31


<PAGE>   38


      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

      The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, PROVIDED that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

      SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Company, together with, in proper cases, such
security or indemnity as may be required by the Company or the Trustee to save
each of them or any agent of either of them harmless, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

      If there shall be delivered to the Company and to the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security or
coupon, and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any,

                                       32


<PAGE>   39


appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains.

      Notwithstanding the provisions of the previous two paragraphs, in case any
such mutilated, destroyed, lost or stolen Security or coupon has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; PROVIDED, HOWEVER, that payment of principal of (and premium or Make-
Whole Amount, if any), and any interest on, Bearer Securities shall, except as
otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

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

      Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon 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 and their
coupons, if any, 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 or coupons.

      SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that 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 at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; PROVIDED, HOWEVER, that each
installment of interest on any Registered Security may at the Company's option
be paid by (i) mailing a check for such interest, payable to or upon the written
order of the Person entitled thereto pursuant to Section

                                       33


<PAGE>   40


308, to the address of such Person as it appears on the Security Register or
(ii) transfer to an account maintained by the payee located inside the United
States.

      Unless otherwise provided as contemplated by Section 301 with respect to
the Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

      Unless otherwise provided as contemplated by Section 301, every permanent
global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case may be,
with respect to that portion of such permanent global Security held for its
account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

      In case a Bearer Security of any series is surrendered in exchange for a
Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that 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 registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Company shall deposit with the Trustee an amount of money in the currency
      or currencies, currency unit or units or composite currency or currencies
      in which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series) equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest

                                       34


<PAGE>   41


      or shall make arrangements satisfactory to the Trustee for such deposit on
      or prior to the date of the proposed payment, such money when deposited to
      be held in trust for the benefit of the Persons entitled to such Defaulted
      Interest as in this clause provided. Thereupon the Trustee shall fix a
      Special Record Date for the payment of such Defaulted Interest which shall
      be not more than 15 days and not less than 10 days prior to the date of
      the proposed payment and not less than 10 days after the receipt by the
      Trustee of the notice of the proposed payment. The Trustee shall promptly
      notify the Company of such Special Record Date and, in the name and at the
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to each Holder of Registered Securities of
      such series at his address as it appears in the Security Register not less
      than 10 days prior to such Special Record Date. The Trustee may, in its
      discretion, in the name and at the expense of the Company, cause a similar
      notice to be published at least once in an Authorized Newspaper in each
      Place of Payment, but such publications shall not be a condition precedent
      to the establishment of such Special Record Date. Notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor
      having been mailed as aforesaid, such Defaulted Interest shall be paid to
      the Persons in whose names the Registered 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). In case a Bearer Security of any
      series is surrendered at the office or agency in a Place of Payment for
      such series in exchange for a Registered Security of such series after the
      close of business at such office or agency on any Special Record Date and
      before the opening of business at such office or agency on the related
      proposed date for payment of Defaulted Interest, such Bearer Security
      shall be surrendered without the coupon relating to such proposed date of
      payment and Defaulted Interest will not be payable on such proposed date
      of payment in respect of the Registered Security issued in exchange for
      such Bearer Security, but will be payable only to the Holder of such
      coupon when due in accordance with the provisions of this Indenture.

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

      Subject to the foregoing provisions of this Section and Section 305, 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
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium or Make-Whole Amount, if any),
and (subject to Sections 305 and 307) interest on, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary. All such payments so
made to any such Person, or upon such Person's order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for money payable upon any such Security.

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

      No Holder of any beneficial interest in any Global Security held on its
behalf by a depository shall have any rights under this Indenture with respect
to such Global Security and such depository shall be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

      Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depository, as a Holder, with respect to
such Global Security or impair, as between such depository and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

      SECTION 309. CANCELLATION. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, 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 any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in

                                       36


<PAGE>   43


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 Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. If the
Company shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. Cancelled Securities and coupons held by the
Trustee shall be destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Company, unless the Trustee is otherwise
directed by a Company Order.

      SECTION 310. COMPUTATION OF INTEREST. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.


                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

      SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall
upon Company Request cease to be of further effect with respect to any series of
Securities specified in such Company Request (except as to any surviving rights
of registration of transfer or exchange of Securities of such series herein
expressly provided for), and the Trustee, upon receipt of a Company Order, and
at the expense of the Company, shall execute instruments in form and substance
satisfactory to the Trustee and the Company acknowledging satisfaction and
discharge of this Indenture as to such series when

                  (1) either

                  (A) all Securities of such series theretofore authenticated
            and delivered and all coupons, if any, appertaining thereto (other
            than (i) coupons appertaining to Bearer Securities surrendered for
            exchange for Registered Securities and maturing after such exchange,
            whose surrender is not required or has been waived as provided in
            Section 305, (ii) Securities and coupons of such series which have
            been destroyed, lost or stolen and which have been replaced or paid
            as provided in Section 306, (iii) coupons appertaining to Securities
            called for redemption and maturing after the relevant Redemption
            Date, whose surrender has been waived as provided in Section 1106,
            and (iv) Securities and coupons of such series for whose payment
            money has theretofore been deposited in trust or segregated and held
            in trust by the Company and thereafter repaid to the Company or
            discharged from such trust, as provided in Section 1003) have been
            delivered to the Trustee for cancellation; or

                                       37


<PAGE>   44


                  (B) all Securities of such series and, in the case of (i) or
            (ii) below, any coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation

                        (i)   have become due and payable, or

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

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

            and the Company, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for the purpose an amount in the currency or
            currencies, currency unit or units or composite currency or
            currencies in which the Securities of such series are payable,
            sufficient to pay and discharge the entire indebtedness on such
            Securities and such coupons not theretofore delivered to the Trustee
            for cancellation, for principal (and premium or Make-Whole Amount,
            if any) and interest to the date of such deposit (in the case of
            Securities which have become due and payable) or to the Stated
            Maturity or Redemption Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

      SECTION 402. APPLICATION OF TRUST FUNDS. Subject to the provisions of the
last paragraph of Section 1003, all money deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the coupons and this Indenture, to the payment,
either directly or through any Paying Agent

                                       38


<PAGE>   45


(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium or
Make-Whole Amount, if any), and any interest for whose payment such money has
been deposited with or received by the Trustee, but such money need not be
segregated from other funds except to the extent required by law.


                             ARTICLE FIVE - REMEDIES

      SECTION 501. EVENTS OF DEFAULT. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not 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):

                  (1) default in the payment of any interest on any Security of
      that series or of any coupon appertaining thereto, when such interest or
      coupon becomes due and payable, and continuance of such default for a
      period of 30 days; or

                  (2) default in the payment of the principal of (or premium or
      Make-Whole Amount, if any, on) any Security of that series when it
      becomes due and payable at its Maturity; or

                  (3)   default in the deposit of any sinking fund payment, 
      when and as due by the terms of any Security of that series; or

                  (4) default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture with respect to any Security of
      that series (other than a covenant or warranty a default in whose
      performance or whose breach is elsewhere in this Section specifically
      dealt with), and continuance of such default or breach for a period of 60
      days after there has been given, by registered or certified mail, to the
      Company by the Trustee or to the Company 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; or

                  (5) default under any bond, debenture, note, mortgage,
      indenture or instrument under which there may be issued or by which there
      may be secured or evidenced any indebtedness for money borrowed by the
      Company (or by any Subsidiary, the repayment of which the Company has
      guaranteed or for which the Company is directly responsible or liable as
      obligor or guarantor), having an aggregate principal amount outstanding of
      at least $25,000,000, whether such indebtedness now exists or shall
      hereafter be created, which default shall have resulted in such

                                       39


<PAGE>   46


      indebtedness becoming or being declared due and payable prior to the date
      on which it would otherwise have become due and payable, without such
      indebtedness having been discharged, or such acceleration having been
      rescinded or annulled, within a period of 10 days after there shall have
      been given, by registered or certified mail, to the Company by the Trustee
      or to the Company and the Trustee by the Holders of at least 10% in
      principal amount of the Outstanding Securities of that series a written
      notice specifying such default and requiring the Company to cause such
      indebtedness to be discharged or cause such acceleration to be rescinded
      or annulled and stating that such notice is a "Notice of Default"
      hereunder; or

                  (6) the Company or any Significant Subsidiary pursuant to 
      or within the meaning of any Bankruptcy Law:

                        (A)   commences a voluntary case,

                        (B)   consents to the entry of an order for relief
            against it in an involuntary case,

                        (C)   consents to the appointment of a Custodian of it 
            or for all or substantially all of its property, or

                        (D)   makes a general assignment for the benefit of its
            creditors; or

                  (7) a court of competent jurisdiction enters an order or
      decree under any Bankruptcy Law that:

                        (A)   is for relief against the Company or any 
            Significant Subsidiary in an involuntary case,

                        (B)   appoints a Custodian of the Company or any 
            Significant Subsidiary or for all or substantially all of either of

            in effect for 90 days; or

                                       40


<PAGE>   47


      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 and 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 (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by the Holders), and upon
any such declaration such principal or specified portion thereof 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 Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration of acceleration and its
consequences if:

                  (1) the Company has paid or deposited with the Trustee a sum
      sufficient to pay in the currency, currency unit or composite currency in
      which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series):

                        (A)   all overdue installments of interest on all 
            Outstanding Securities of that series and any related coupons,

                        (B)   the principal of (and premium or Make-Whole 
            Amount, if any, on) any Outstanding Securities of that series 
            which have become due otherwise than by such declaration of 
            acceleration and interest thereon at the rate or rates borne by 
            or provided for in such Securities,

                        (C)   to the extent that payment of such interest is
            lawful, interest upon overdue installments of interest at the rate
            or rates borne by or provided for 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 nonpayment of the principal of (or premium or
      Make-Whole Amount, if any) or interest on Securities of that series which
      have become due solely by such declaration of acceleration, have been
      cured or waived as provided in Section 513.


                                       41


<PAGE>   48


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

      SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY 
TRUSTEE. The Company covenants that if:

                  (1) default is made in the payment of any installment of
      interest on any Security of any series and any related coupon when such
      interest becomes due and payable and such default continues for a period
      of 30 days, or

                  (2) default is made in the payment of the principal of (or 
      premium or Make-Whole Amount, if any, on) any Security of any series at 
      its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue
installments of interest at the rate or rates borne by or provided for 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 the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

      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 and any
related coupons 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 the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the property of the
Company or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities of any series shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the

                                       42


<PAGE>   49


Trustee shall have made any demand on the Company for the payment of overdue
principal, premium or Make-Whole Amount, if any, or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise:

                        (i) to file and prove a claim for the whole amount, or
      such lesser amount as may be provided for in the Securities of such
      series, of principal (and premium or Make-Whole Amount, if any) and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

                        (ii) 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 of Securities of such series and coupons 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 to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

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

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

      SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES
OR COUPONS. All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons 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 and
coupons 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 premium or Make-Whole Amount, if any) or
interest, upon presentation of the Securities or coupons, or both, as the case
may be, 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 and any 
      predecessor Trustee under Section 606;

            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, 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 aggregate amounts due and payable on such
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, respectively; and

            THIRD:  To the payment of the remainder, if any, to the Company.

      SECTION 507. LIMITATION ON SUITS. No Holder of any Security of any series
or any related coupon 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 25% 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 reasonably 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;


                                       44


<PAGE>   51


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 such
Holders.

      SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
OR MAKE-WHOLE AMOUNT, IF ANY, AND INTEREST. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right
which is absolute and unconditional to receive payment of the principal of (and
premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (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 of a Security or coupon 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, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, 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 or coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities or coupons is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      SECTION 511. DELAY OR OMISSION NOT WAIVER. No delay or omission of the
Trustee or of any Holder of any Security or coupon 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 of Securities or coupons, as the
case may be.


                                       45


<PAGE>   52


      SECTION 512. CONTROL BY HOLDERS OF SECURITIES. The Holders of not less
than 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)   the Trustee need not take any action which might involve
      it in personal liability or be unduly prejudicial to the Holders of
      Securities of such series not joining therein.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

      SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

                  (1)   in the payment of the principal of (or premium or 
      Make-Whole Amount, if any) or interest on any Security of such series or 
      any related coupons, or

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

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

      SECTION 514. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will

                                       46


<PAGE>   53


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 515. UNDERTAKING FOR COSTS. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, 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 or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).


                            ARTICLE SIX - THE TRUSTEE

      SECTION 601. NOTICE OF DEFAULTS. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking fund installment with respect to the Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interests of the Holders of the Securities and coupons
of such series; and PROVIDED FURTHER that in the case of any default or breach
of the character specified in Section 501(4) with respect to the Securities and
coupons of such series, no such notice to Holders shall be given until at least
60 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 the Securities of such series.

      SECTION 602. CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of TIA
Section 315(a) through 315(d):

                  (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, coupon or other paper

                                       47


<PAGE>   54


      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 Company mentioned herein
      shall be sufficiently evidenced by a Company Request or Company Order
      (other than delivery of any Security, together with any coupons
      appertaining thereto, to the Trustee for authentication and delivery
      pursuant to Section 303 which shall be sufficiently evidenced as provided
      therein) and any resolution of the Board of Directors may 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;

                  (4) the Trustee may consult with counsel and the written
      advice of such counsel or any Opinion of Counsel shall be full and
      complete authorization and protection in respect of any action taken,
      suffered or omitted by it hereunder in good faith and in reliance thereon;

                  (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 of Securities of any series or any related
      coupons pursuant to this Indenture, unless such Holders shall have offered
      to the Trustee security or indemnity reasonably satisfactory to the
      Trustee 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, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; PROVIDED that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the

                                       48


<PAGE>   55


      Company, relevant to the facts or matters that are the subject of its 
      inquiry, personally or by agent or attorney;

                  (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; and

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

      The Trustee shall not be required 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.

      Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

      SECTION 603. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Company, 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 coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

      SECTION 604. MAY HOLD SECURITIES. The Trustee, any Paying Agent, Security
Registrar, Authenticating Agent or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with
the Company with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar, Authenticating Agent or such other agent.

      SECTION 605. 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 with the Company.


                                       49


<PAGE>   56


      SECTION 606. COMPENSATION AND REIMBURSEMENT. The Company agrees:

                  (1) to pay to the Trustee from time to time reasonable
      compensation 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 each of the Trustee and any predecessor 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 reasonable expenses and
      disbursements of its agents and counsel), except any such expense,
      disbursement or advance as may be attributable to its negligence or bad
      faith; and

                  (3) to indemnify each of the Trustee and any predecessor
      Trustee for, and to hold it harmless against, any loss, liability or
      expense incurred without negligence or bad faith on its part, arising out
      of or in connection with the acceptance or administration of the trust 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.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(7) or Section 501(8), 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.

      As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest on particular Securities or any coupons.

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

      SECTION 607. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and

                                       50


<PAGE>   57


with the effect hereinafter specified in this Article. Neither the Company nor
any Person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as Trustee.

      SECTION 608. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

            (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 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.

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

            (d)   IF AT ANY TIME:

                  (1) the Trustee shall fail to comply with the provisions of
      TIA Section 310(b) after written request therefor by the Company or by any
      Holder of a Security 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 607
      and shall fail to resign after written request therefor by the Company or
      by any Holder of a Security who has been a bona fide Holder of a Security
      for at least six months, 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, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security 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.


                                       51


<PAGE>   58


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

            (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided for notices to the Holders of Securities 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 609. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) 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 Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company 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 nevertheless to its claim, if any, provided for in
Section 606.

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and

                                       52


<PAGE>   59


deliver an indenture supplemental hereto, pursuant to Article Nine hereof,
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 Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 609, as the case may be.

            (d) 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 610. 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 of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, PROVIDED such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons 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 or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such

                                       53


<PAGE>   60


Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. APPOINTMENT OF AUTHENTICATING AGENT. At any time when any of
the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents 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 or
repayment thereof, 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. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Company.
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 Company and shall at all times
be a bank or trust company or corporation organized and doing business and in
good standing under the laws of the United States of America or of any state 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 authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid 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. In case 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 such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

      An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent

                                       54


<PAGE>   61


by giving written notice of termination to such Authenticating Agent and to the
Company. 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 for such series may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall give notice of such appointment to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve in the
manner set forth in Section 106. 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 herein. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

      The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation including reimbursement of its reasonable expenses 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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

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

                                    [_______________]
                                        as Trustee

                                       as Authenticating Agent

      SECTION 612.  CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

      (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

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


                                       55


<PAGE>   62


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

      (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

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

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

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

            (3) the Trustee shall not be liable with respect to any action taken
      or omitted to be taken by it in good faith in accordance with the
      direction of the Holders of a majority in principal amount of the
      Outstanding Securities of any series relating to the time, method and
      place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series; and

            (4) 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.

      (d) 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
612.

Authenticating Agent nor any Paying Agent nor any Security Registrar shall be
held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities in accordance with TIA Section 312,

semiannually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

            (b) at such other times as the Trustee may request in writing,

<PAGE>   65


      SECTION 802. RIGHTS AND DUTIES OF SUCCESSOR CORPORATION. In case of any
such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

      In case of any such consolidation, merger, sale, lease or conveyance, such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

      SECTION 803. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.


                     ARTICLE NINE - SUPPLEMENTAL INDENTURES

      SECTION 901. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS. Without
the consent of any Holders of Securities or coupons, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental

                  (2) to add to the covenants of the Company 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
      Company; or

                  (3) to add any additional Events of Default for the benefit of

      Default are to be for the benefit of less than all series of Securities,
      stating that such Events of Default are expressly being included solely
      for the benefit of such series); PROVIDED, HOWEVER, that in respect of any
      such additional Events of Default such supplemental indenture may provide
      for a particular period of grace after default (which period may be
      shorter or longer than that allowed in the case of other defaults) or may
      provide for an immediate enforcement upon such default or may limit the
      remedies available to the Trustee upon such default or may limit the right
      of the Holders of a majority in aggregate principal amount of that or
      those series of Securities to which such additional Events of Default
      apply to waive such default; or

                  (4) to add to or change any of the provisions of this
      Indenture to provide that Bearer Securities may be registrable as to

      for Registered Securities, to permit Bearer Securities to be issued in
      exchange for Bearer Securities of other authorized denominations or to
      permit or facilitate the issuance of Securities in uncertificated form,
      PROVIDED that any such action shall not adversely affect the interests of
      the Holders of Securities of any series or any related coupons in any
      material respect; or

                  (5) to change or eliminate any of the provisions of this
      Indenture, PROVIDED that any such change or elimination shall become
      effective only when there is no Security Outstanding of any series created
      prior to the execution of such supplemental indenture which is entitled to
      the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any 
      series and any related coupons 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; or

                                       60


<PAGE>   67


                  (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 which shall not be inconsistent
      with the provisions of this Indenture, PROVIDED such provisions shall not
      adversely affect the interests of the Holders of Securities of any series
      or any related coupons in any material respect; or

                  (10) to supplement any of the provisions of this Indenture to
      such extent as shall be necessary to permit or facilitate the defeasance
      and discharge of any series of Securities pursuant to Sections 401, 1402
      and 1403; PROVIDED that any such action shall not adversely affect the
      interests of the Holders of Securities of such series and any related
      coupons or any other series of Securities 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 all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by or pursuant to 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 modifying in any manner the rights of the Holders of
Securities and any related coupons 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 premium
      or Make-Whole Amount, if any, on) or any installment of principal of or
      interest on, any Security; or reduce the principal amount thereof or the
      rate or amount of interest thereon, or any premium or Make-Whole Amount
      payable upon the redemption thereof, or reduce the amount of the principal
      of an Original Issue Discount Security that would be due and payable upon
      a declaration of acceleration of the Maturity thereof pursuant to Section
      502 or the amount thereof provable in bankruptcy pursuant to Section 504,
      or adversely affect any right of repayment at the option of the Holder of
      any Security, or change any Place of Payment where, or the currency or
      currencies, currency unit or units or composite currency or currencies in
      which, any Security or any premium or Make-Whole Amount or the 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 or repayment at the option of the Holder,
      on or after the Redemption Date or the Repayment Date, as the case may
      be), 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

                                       61


<PAGE>   68


      certain defaults hereunder and their consequences) provided for in this
      Indenture, or reduce the requirements of Section 1504 for quorum or
      voting, or

                  (3) modify any of the provisions of this Section, Section 513
      or Section 1009, except to increase the required percentage to effect such
      action 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 902 and Section 1009, or the deletion of this proviso, in
      accordance with the requirements of Sections 609(b) and 901(11).

      It shall not be necessary for any Act of Holders under this Section 902 to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

      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.

      SECTION 903. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or

indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

                             ARTICLE TEN - COVENANTS

      SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM OR MAKE-WHOLE AMOUNT, IF ANY;
AND INTEREST. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium or Make-Whole Amount, if any) and interest on the Securities of
that series in accordance with the terms of such series of Securities, any
coupons appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any
interest due on Bearer Securities on or before Maturity shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. Unless otherwise
specified with respect to Securities of any series pursuant to Section 301, at
the option of the Company, all payments of principal may be paid by check to the
registered Holder of the Registered Security or other person entitled thereto
against surrender of such Security.

      SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series
are issuable only as Registered Securities, the Company shall 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 Company in respect of the
Securities of that series and this Indenture may be served. If Securities of a
series are issuable as Bearer Securities, the Company will maintain: (A) in the
Borough of Manhattan, The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise); (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment; PROVIDED, HOWEVER, that if the Securities
of that series are listed on any stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in any required city located
outside the United States, as the case may be, so long as the Securities of that
series are listed on such exchange; and (C) subject to any

                                       63


<PAGE>   70


laws or regulations applicable thereto, in a Place of Payment for that series
located outside the United States an office or agency where any Registered
Securities of that series may be surrendered for registration of transfer, where
Securities of that series may be surrendered for exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of each such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of that
series and the related coupons may be presented and surrendered for payment at
the offices specified in the Security, in London, England, and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Company hereby appoints the Trustee its
agent to receive all such presentations, surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or Make-Whole Amount or interest
on Bearer Securities shall be made at any office or agency of the Company in the
United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States;
PROVIDED, HOWEVER, that, if the Securities of a series are payable in Dollars,
payment of principal of and any premium or Make-Whole Amount and interest on any
Bearer Security shall be made at the office of the Company's Paying Agent in the
Borough of Manhattan, The City of New York, if (but only if) payment in Dollars
of the full amount of such principal, premium or Make-Whole Amount, or interest,
as the case may be, at all offices or agencies outside the United States
maintained for the purpose by the Company in accordance with this Indenture, is
illegal or effectively precluded by exchange controls or other similar
restrictions.

      The Company may 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 of such purposes, and may from time to time rescind
such designations; PROVIDED, HOWEVER, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Company hereby designates as a Place of Payment for each series of
Securities the office or agency of the Company in the Borough of Manhattan, The
City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

      SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the
Company shall at any time act as its own Paying Agent with respect to any series
of any Securities and any related coupons, it will, on or before each due date
of the principal of (and premium or Make-Whole Amount, if any), 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 in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of its action or failure so to
act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities and any related coupons, it will, on or before each due date of
the principal of (and premium or Make-Whole Amount, if any), or interest on any
Securities of that series, deposit with a Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal (and premium or
Make-Whole Amount, if any) or interest so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
Make-Whole Amount, if any, or interest and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee 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) hold all sums held by it for the payment of principal of
      (and premium or Make-Whole Amount, if any) or interest on Securities in
      trust for the benefit of the Persons entitled thereto until such sums
      shall be paid to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Company (or
      any other obligor upon the Securities) in the making of any such payment
      of principal (and premium or Make-Whole Amount, if any) or interest on the
      Securities of that series; and


                                       65


<PAGE>   72


                  (3) at any time during the continuance of any such default
      upon the written request of the Trustee, forthwith pay to the Trustee all
      sums so held in trust by such Paying Agent.

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

      Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium or Make-Whole Amount, if any) or
interest has become due and payable shall be paid to the Company upon Company
Request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and premium
or Make-Whole Amount, if any) or interest on any Security, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in an Authorized Newspaper, 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 Company.

      SECTION 1004. EXISTENCE. Subject to Article Eight, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, all material rights (by articles of
incorporation, by-laws and statute) and material franchises; PROVIDED, HOWEVER,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

      SECTION 1005. MAINTENANCE OF PROPERTIES. The Company will cause all of its
material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; PROVIDED, HOWEVER, that the Company and its

                                       66


<PAGE>   73


Subsidiaries shall not be prevented from selling or otherwise disposing of their
properties for value in the ordinary course of business.

      SECTION 1006. INSURANCE. The Company will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount deemed reasonable by the Board of Directors with insurers of recognized
responsibility.

      SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; PROVIDED, HOWEVER, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

      SECTION 1008. STATEMENT AS TO COMPLIANCE. The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year, a brief certificate
from the principal executive officer, principal financial officer or principal
accounting officer as to his or her knowledge of the Company's compliance with
all conditions and covenants under this Indenture and, in the event of any
noncompliance, specifying such noncompliance and the nature and status thereof.
For purposes of this Section 1008, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

      SECTION 1009. WAIVER OF CERTAIN COVENANTS. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1009, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

      SECTION 1101. APPLICABILITY OF ARTICLE. Securities of any series which are

<PAGE>   74


      SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of the
Company to redeem any Securities shall be evidenced by or pursuant to a Board
Resolution. In case of any redemption at the election of the Company of less
than all of the Securities of any series, the Company shall, at least 45 days
prior to the giving of the notice of redemption in Section 1104 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

      SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED. If less
than all the Securities of any series issued on the same day with the same terms
are to be redeemed, 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 issued on such date with the same terms
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
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

      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 Security redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

      SECTION 1104. NOTICE OF REDEMPTION. Notice of redemption shall be given in
the manner provided in Section 106, not less than 30 days nor more than 60 days
prior to the Redemption Date, unless a shorter period is specified by the terms
of such series established pursuant to Section 301, to each Holder of Securities
to be redeemed, but failure to give such notice in the manner herein provided to
the Holder of any Security designated for redemption as a whole or in part, or
any defect in the notice to any such Holder, shall not affect the validity of
the proceedings for the redemption of any other such Security or portion
thereof.

      Any notice that is mailed to the Holders of Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives the notice.

      All notices of redemption shall state:

                                       68


<PAGE>   75


                  (1) the Redemption Date,

                  (2) the Redemption Price, accrued interest to the 
      Redemption Date payable as provided in Section 1106, if any,

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

                  (4) in case any Security is to be redeemed in part only, the
      notice which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the holder will receive,
      without a charge, a new Security or Securities of authorized denominations
      for the principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price and
      accrued interest to the Redemption Date payable as provided in Section
      1106, if any, will become due and payable upon each such Security, or the
      portion thereof, to be redeemed and, if applicable, that interest thereon
      shall cease to accrue on and after said date,

                  (6) the Place or Places of Payment where such Securities,
      together in the case of Bearer Securities with all coupons appertaining
      thereto, if any, maturing after the Redemption Date, are to be surrendered
      for payment of the Redemption Price and accrued interest, if any,

                  (7) that the redemption is for a sinking fund, if such is 
      the case,

                  (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing coupon or coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Company, the Trustee for such series and any Paying
      Agent is furnished,

                  (9) if Bearer Securities of any series are to be redeemed and
      any Registered Securities of such series are not to be redeemed, and if
      such Bearer Securities may be exchanged for Registered Securities not
      subject to redemption on this Redemption Date pursuant to Section 305 or
      otherwise, the last date, as determined by the Company, on which such
      exchanges may be made, and

                  (10) the CUSIP number of such Security, if any.


                                       69


<PAGE>   76


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

      SECTION 1105. DEPOSIT OF REDEMPTION PRICE. On or prior to any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, which it may not do in the case
of a sinking fund payment under Article Twelve, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

      SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of redemption
having been given as aforesaid, the Securities so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein
specified in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) (together with accrued interest, if any, to the Redemption Date),
and from and after such date (unless the Company shall default in the payment of
the Redemption Price and accrued interest) such Securities shall, if the same
were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent
provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest, if
any, to the Redemption Date; PROVIDED, HOWEVER, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and PROVIDED further that installments of interest on
Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to

                                       70


<PAGE>   77


save each of them and any Paying Agent harmless. If thereafter the Holder of
such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made from the
Redemption Price, such Holder shall be entitled to receive the amount so
deducted; PROVIDED, HOWEVER, that interest represented by coupons shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of those
coupons.

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium or Make-Whole Amount, if any)
shall, until paid, bear interest from the Redemption Date at the rate borne by
the Security.

      SECTION 1107. SECURITIES REDEEMED IN PART. Any Registered Security which
is to be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) shall be surrendered at a Place of Payment therefor (with, if
the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge a new Security or Securities of
the same series, 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. If a Global Security is so
surrendered, the Company shall execute and the Trustee shall authenticate and
deliver to the depository, without service charge, a new Global Security in a
denomination equal to and in exchange for the unredeemed portion of the
principal of the Global Security so surrendered.


                         ARTICLE TWELVE - 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 a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series 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 of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory 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 of any series as provided for by the
terms of Securities of such series.


                                       71


<PAGE>   78


      SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The
Company may, in satisfaction of all or any part of any mandatory sinking fund
payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; PROVIDED that such Securities so delivered or applied as a credit have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.

      SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60
days prior to each sinking fund payment date for Securities of any series, the
Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Company shall thereupon be obligated to pay the amount
therein specified. Not less than 30 days before 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
Company in the manner provided in Section 1104. Such notice having been duly

manner stated in Sections 1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

      SECTION 1301. APPLICABILITY OF ARTICLE. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.


                                       72


<PAGE>   79


      SECTION 1302. REPAYMENT OF SECURITIES. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless
otherwise provided in the terms of such Securities, be repaid at a price equal
to the principal amount thereof, together with interest, if any, thereon accrued
to the Repayment Date specified in or pursuant to the terms of such Securities.
The Company covenants that on or prior to the Repayment Date it will deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay the principal (or, if so provided by the terms of
the Securities of any series, a percentage of the principal) of, and (except if
the Repayment Date shall be an Interest Payment Date) accrued interest on, all
the Securities or portions thereof, as the case may be, to be repaid on such
date.

      SECTION 1303. EXERCISE OF OPTION. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Company shall from time to time notify the Holders of
such Securities) not earlier than 60 days nor later than 30 days prior to the
Repayment Date (1) the Security so providing for such repayment together with
the "Option to Elect Repayment" form on the reverse thereof duly completed by
the Holder (or by the Holder's attorney duly authorized in writing) or (2) a
telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in the United States setting
forth the name of the Holder of the Security, the principal amount of the
Security, the principal amount of the Security to be repaid, the CUSIP number,
if any, or a description of the tenor and terms of the Security, a statement
that the option to elect repayment is being exercised thereby and a guarantee
that the Security to be repaid, together with the duly completed form entitled
"Option to Elect Repayment" on the reverse of the Security, will be received by
the Trustee not later than the fifth Business Day after the date of such
telegram, telex, facsimile transmission or letter; PROVIDED, HOWEVER, that such
telegram, telex, facsimile transmission or letter shall only be effective if
such Security and form duly completed are received by the Trustee by such fifth
Business Day. If less than the entire principal amount of such Security is to be
repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing

                                       73


<PAGE>   80


for repayment at the option of the Holder thereof, exercise of the repayment
option by the Holder shall be irrevocable unless waived by the Company.

      SECTION 1304. WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
PROVIDED, HOWEVER, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and PROVIDED FURTHER that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Company shall default in the payment thereof) 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 Bearer Security surrendered for repayment shall not be accompanied
by all appurtenant coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable therefor as provided in Section
1302 an amount equal to the face amount of all such missing coupons, or the
surrender of such missing coupon or coupons may be waived by the Company and the
Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted; PROVIDED, HOWEVER, that interest represented by coupons
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of those
coupons.

      If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at

                                       74


<PAGE>   81


the rate of interest or Yield to Maturity (in the case of Original Issue
Discount Securities) set forth in such Security.

      SECTION 1305. SECURITIES REPAID IN PART. Upon surrender of any Registered
Security which is to be repaid in part only, the Company shall execute and the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge and at the expense of the Company, a new Registered Security or
Securities of the same series, of any authorized denomination specified by the
Holder, in an aggregate principal amount equal to and in exchange for the
portion of the principal of such Security so surrendered which is not to be
repaid.


              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

      SECTION 1401. APPLICABILITY OF ARTICLE: COMPANY'S OPTION TO EFFECT
DEFEASANCE OR COVENANT DEFEASANCE. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

      SECTION 1402. DEFEASANCE AND DISCHARGE. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Securities and

                                       75


<PAGE>   82


any coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Company may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such
Securities and any coupons appertaining thereto.

      SECTION 1403. COVENANT DEFEASANCE. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, "covenant defeasance"), and such Securities and
any coupons appertaining thereto shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 1004 to 1009, inclusive, or such other covenant, but shall continue to
be deemed "Outstanding" for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a default or an Event of Default under Section 501(4) or
501(8) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby.

      SECTION 1404. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

            (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article

following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with

                                       76


<PAGE>   83


their terms will provide, not later than the due date of any payment of
principal of (and premium or Make-Whole Amount, if any) and interest, if any, on
such Securities and any coupons appertaining thereto, money in an amount, or (3)
a combination thereof, in any case, in an amount, sufficient, without
consideration of any reinvestment of such principal and interest, 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 (or other qualifying trustee) to pay
and discharge, (i) the principal of (and premium or Make-Whole Amount, if any)
and interest, if any, on such Outstanding Securities and any coupons
appertaining thereto on the Stated Maturity of such principal or installment of
principal or interest and (ii) any mandatory sinking fund payments or analogous
payments applicable to such Outstanding Securities and any coupons appertaining
thereto on the day on which such payments are due and payable in accordance with
the terms of this Indenture and of such Securities and any coupons appertaining
thereto.

breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

            (c) No Event of Default or event which with notice or lapse of time
or both would become an Event of Default with respect to such Securities and any
coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit or, insofar as Sections 501(6) and 501(7) are concerned, at any
time during the period ending on the 91st day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until the
expiration of such period).

            (d) In the case of an election under Section 1402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling, or (ii) since the date of execution of this Indenture, there has been
a change in the applicable Federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Outstanding Securities and any coupons appertaining thereto will not recognize
income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance
had not occurred.

            (e) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

<PAGE>   84


            (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

            (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

      SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium or Make-Whole Amount, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

      Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency

                                       78


<PAGE>   85


unit in effect on the second Business Day prior to each payment date, except,
with respect to a Conversion Event, for such currency or currency unit in effect
(as nearly as feasible) at the time of the Conversion Event.

      The Company 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 1404 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 such Outstanding Securities and any coupons
appertaining thereto.

      Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon Company Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 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 a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

      SECTION 1505. DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF
MEETINGS. (a) Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to

written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the

            (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; PROVIDED,
HOWEVER, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting

based hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any past, present or

any successor, either directly or through the Company or any successor, whether
by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,

      SECTION 102. COMPLIANCE CERTIFICATES AND OPINIONS. Upon any application or
request by the Company to the Trustee to take any action under any provision of
this Indenture, the Company shall furnish to the Trustee an Officers'
Certificate stating that all conditions precedent, if any, provided for in this
Indenture relating to the proposed action have been complied with and an Opinion

                                       12


<PAGE>   20


            (2) a brief statement as to the nature and scope of the examination
      or investigation upon which the statements or opinions contained in such
      certificate or opinion are based;

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

      SECTION 104. ACTS OF HOLDERS. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and

                                       13


<PAGE>   21


held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and conclusive
in favor of the Trustee and the Company and any agent of the Trustee or the
Company, if made in the manner provided in this Section. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

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

            (c) The ownership of Registered Securities shall be proved by the
Security Register. As to any matter relating to beneficial ownership interests
in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

            (d) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depository, by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depository, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

            (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date

                                       14


<PAGE>   22


for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. Notwithstanding TIA Section 316(c), such
record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not later
than the date such solicitation is completed. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; PROVIDED that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

            (f) 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, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

      SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY. 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 Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at [__________________________]; or

                  (2) the Company by the Trustee or by any Holder shall be
      sufficient for every purpose hereunder (unless otherwise herein expressly
      provided) if in writing and mailed, first class postage prepaid, to the
      Company addressed to it at the address of its principal office specified
      in the first paragraph of this Indenture or at any other address
      previously furnished in writing to the Trustee by the Company, Attention:
      Chief Financial Officer (with a copy to the Company's General Counsel), or

                  (3) either the Trustee or the Company, by the other party,
      shall be sufficient for every purpose hereunder if given by facsimile
      transmission, receipt confirmed by telephone followed by an original copy
      delivered by guaranteed overnight courier; if to the Trustee at facsimile
      number [_________________]; and if to the Company at facsimile number
      (415) 391-6259.

<PAGE>   23


      SECTION 106. NOTICE TO HOLDERS: WAIVER. Where this Indenture provides for
notice of any event to Holders of Registered Securities by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such 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 of Registered Securities 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 of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

      Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer Securities of any event, such notice shall be
sufficiently given if published in an Authorized Newspaper in The City of New
York and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, if any,
and not earlier than the earliest date, if any, prescribed for the giving of
such notice. Any such notice shall be deemed to have been given on the date of
such publication or, if published more than once, on the date of the first such
publication.

      If by reason of the suspension of publication of any Authorized Newspaper
or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

      Any request, demand, authorization, direction, notice, consent or waiver
required or permitted under this Indenture shall be in the English language,
except that any published notice may be in an official language of the country
of publication.

      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

                                       16


<PAGE>   24


the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

      SECTION 107. COUNTERPARTS; EFFECT OF HEADINGS AND TABLE OF CONTENTS. This
Indenture 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 Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

      SECTION 108. SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Indenture by the Company shall bind its successors and assigns, whether so 
expressed or not.

      SECTION 109. SEVERABILITY CLAUSE. In case any provision in this Indenture
or in any Security or coupon 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 110. BENEFITS OF INDENTURE. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
Agent and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

      SECTION 111. GOVERNING LAW. This Indenture and the Securities and coupons
shall be governed by and construed in accordance with the law of the State of
New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

      SECTION 112. LEGAL HOLIDAYS. In any case where any Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
convert or exchange a Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or principal (and premium or Make-Whole Amount, if any) or conversion
or exchange of such security need not be made at such Place of Payment on such
date, but (except as otherwise provided in the supplemental indenture with
respect to such Security) 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, Redemption Date, Repayment Date or sinking fund payment date, or
at the Stated Maturity or Maturity, or on such last day for conversion or
exchange, PROVIDED that no interest shall accrue on the amount so payable for
the period from and after such Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity, as the case may
be.

      SECTION 113. IMMUNITY OF STOCKHOLDERS, DIRECTORS, OFFICERS AND AGENTS OF
THE COMPANY. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
and as part of the consideration for the issue of the Securities.

      SECTION 114. CONFLICT WITH TRUST INDENTURE ACT. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.


                         ARTICLE TWO - SECURITIES FORMS

      SECTION 201. FORMS OF SECURITIES. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be substantially in the form of EXHIBIT A hereto or in such other
form as shall be established in one or more indentures supplemental hereto or
approved from time to time by or pursuant to a Board Resolution in accordance
with Section 301, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements placed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be required to

      SECTION 202. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. Subject to
Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

      This is one of the Securities of the series designated therein referred to

                                          [                   ]
                                               as Trustee


Dated:                                     By:
       ---------------------                   -------------------------------

      SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner or by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 303 or 304. Subject to the provisions of Section 303 and, if
applicable, Section 304, the Trustee shall deliver and redeliver any Global
Security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Global Security shall be in writing but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

      The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security
together with written instructions (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 303.

      Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium or
Make-Whole Amount, if any, and interest on any Global Security in permanent
global form shall be made to the registered Holder thereof.

                                       19


<PAGE>   27


      Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or CEDEL.

      Any Global Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

            "This Security is a Global Security within the meaning set forth in
            the Indenture hereinafter referred to and is registered in the name
            of a Depository or a nominee of a Depository. This Security is
            exchangeable for Securities registered in the name of a person other
            than the Depository or its nominee only in the limited circumstances
            described in the Indenture, and may not be transferred except as a
            whole by the Depository to a nominee of the Depository or by a
            nominee of the Depository to the Depository or another nominee of
            the Depository or by the Depository or its nominee to a successor
            Depository or its nominee."

hereto, prior to the issuance of Securities of any series:

      distinguish the Securities of such series from all other series of

      Securities of the series that may be authenticated and delivered under
      this Indenture (except for Securities authenticated and delivered upon
      registration of transfer of, or in exchange for, or in lieu of, other
      Securities of the series pursuant to Section 304, 305, 306, 906, 1107 or
      1305);

      amount thereof) at which such Securities will be issued and, if other than
      the principal amount thereof, the portion of the principal amount thereof
      payable upon declaration of acceleration of the maturity thereof, or (if
      applicable) the portion of the principal amount of such Securities that is
      convertible into Common Stock or Preferred Stock, or the method by which
      any such portion shall be determined;

                  (4) If convertible, the terms on which such Securities are
      convertible, including the initial conversion price or rate and the
      conversion period and any applicable limitations on the ownership or
      transferability of Common Stock or Preferred Stock receivable on
      conversion;

                  (5) The date or dates, or the method for determining such date
      or dates, on which the principal of such Securities will be payable;

                  (6) The rate or rates (which may be fixed or variable), or the
      method by which such rate or rates shall be determined, at which such
      Securities will bear interest, if any;

                  (7) The date or dates, or the method for determining such date
      or dates, from which any such interest will accrue, the dates on which any

      served;

                  (9) The period or periods, if any, within which, the price or
      prices at which and the other terms and conditions upon which such
      Securities may, pursuant to any optional or mandatory redemption
      provisions, be redeemed, as a whole or in part, at the option of the
      Company;

                  (10) The obligation, if any, of the Company to redeem, repay
      or purchase such Securities pursuant to any sinking fund or analogous
      provision or at the option of a holder thereof, and the period or periods

      conditions upon which such Securities will be redeemed, repaid or
      purchased, as a whole or in part, pursuant to such obligation;

                  (11) If other than Dollars, the currency or currencies in
      which such Securities are denominated and payable, which may be a foreign

      shall be determined;

                  (13) Whether the principal of (and premium or Make-Whole

                  (14) Provisions, if any, granting special rights to the
      holders of Securities of the series upon the occurrence of such events as
      may be specified;

                  (15) Any deletions from, modifications of or additions to the
      Events of Default or covenants of the Company with respect to Securities
      of the series, whether or not such Events of Default or covenants are
      consistent with the Events of Default or covenants set forth herein;

                  (16) Whether and under what circumstances the Company will pay
      any additional amounts on such Securities in respect of any tax,

<PAGE>   30


      of the series are to be issuable initially in temporary global form and
      whether any Securities of the series are to be issuable in permanent
      global form with or without coupons and, if so, whether beneficial owners
      of interests in any such permanent global Security may exchange such
      interests for Securities of such series and of like tenor of any
      authorized form and denomination and the circumstances under which any
      such exchanges may occur, if other than in the manner provided in the
      Indenture, and, if Registered Securities of the series are to be issuable

      the first Security of the series to be issued;

                  (19) The Person to whom any interest on any Registered
      Security of the series shall be payable, if other than the Person in whose
      name that Security (or one or more Predecessor Securities) is registered

      manner in which, or the Person to whom, any interest on any Bearer
      Security of the series shall be payable, if otherwise than upon
      presentation and surrender of the coupons appertaining thereto as they
      severally mature, and the extent to which, or the manner in which, any

                  (20)  The applicability, if any, of the defeasance and 
      covenant defeasance provisions of Article Fourteen hereof to the 
      Securities of the series;

                  (21) If the Securities of such series are to be issuable in
      definitive form (whether upon original issue or upon exchange of a
      temporary Security of such series) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then
      the form and/or terms of such certificates, documents or conditions;

                  (22) The obligation, if any, of the Company to permit the
      conversion of the Securities of such series into Common Stock or Preferred
      Stock, as the case may be, and the terms and conditions upon which such
      conversion shall be effected (including, without limitation, the initial
      conversion price or rate, the conversion period, any adjustment of the
      applicable conversion price and any requirements relative to the
      reservation of such shares for purposes of conversion); and

                  (23) Any other terms of the series (which terms shall not be
      inconsistent with the provisions of this Indenture).


                                       23


<PAGE>   31


      All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

      If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the Securities
of such series.

      SECTION 302. DENOMINATIONS. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series, other than Global Securities (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof.

      SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

      Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and PROVIDED FURTHER
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive

                                       24


<PAGE>   32


such Bearer Security shall have furnished a certificate to Euroclear or CEDEL,
as the case may be, in the form set forth in Exhibit B-1 to this Indenture or
such other certificate as may be specified with respect to any series of
Securities pursuant to Section 301, dated no earlier than 15 days prior to the
earlier of the date on which such Bearer Security is delivered and the date on
which any temporary Security first becomes exchangeable for such Bearer Security
in accordance with the terms of such temporary Security and this Indenture. If
any Security shall be represented by a permanent global Bearer Security, then,
for purposes of this Section and Section 304, the notation of a beneficial
owner's interest therein upon original issuance of such Security or upon
exchange of a portion of a temporary Global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in such permanent Global Security. Except as permitted by Section 306,
the Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured have been detached and canceled.

      If all the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such Securities and determining the terms of particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue. 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 TIA Section 315(a) through 315(d)) shall be fully protected in
relying upon,

            (i)   an Opinion of Counsel stating that

                  (a) the form or forms of such Securities and any coupons have
            been established in conformity with the provisions of this 
            Indenture;

                  (b) the terms of such Securities and any coupons have been
            established in conformity with the provisions of this Indenture; and

                  (c) such Securities, together with any coupons appertaining
            thereto, when completed by appropriate insertions and executed and
            delivered by the Company to the Trustee for authentication in
            accordance with this Indenture, authenticated and delivered by the
            Trustee in accordance with this Indenture and issued by the Company
            in the manner and subject to any conditions specified in such
            Opinion of Counsel, will constitute legal, valid and legally binding
            obligations of the Company, enforceable in accordance with their
            terms, subject to applicable bankruptcy, insolvency, fraudulent
            transfer, reorganization and other similar laws of general
            applicability relating to or affecting the enforcement of creditors'
            rights generally and to general equitable principles; and


                                       25


<PAGE>   33


            (ii) an Officers' Certificate stating that all conditions precedent
      provided for in this Indenture relating to the issuance of the Securities
      have been complied with and that, to the best of the knowledge of the
      signers of such certificate, that no Event of Default with respect to any
      of the Securities shall have occurred and be continuing.

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,
obligations 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 the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

      Each Registered Security shall be dated the date of its authentication and
each Bearer Security shall be dated as of the date specified as contemplated by
Section 301.

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture. Notwithstanding the foregoing, if any Security
(including a Global Security) shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 102 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, 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.
                    ---------------------

      (a) Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and

                                       26


<PAGE>   34


other variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. In the case of
Securities of any series, such temporary Securities may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution), if temporary Securities of any series are issued, the
Company will cause definitive Securities of that series to be prepared without
unreasonable delay. After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company 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 (accompanied by any
non-matured coupons appertaining thereto), the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations;
PROVIDED, HOWEVER, that no definitive Bearer Security shall be delivered in
exchange for a temporary Registered Security; and PROVIDED FURTHER that a
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303. 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.

      (b) Unless otherwise provided in or pursuant to a Board Resolution, the
following provisions of this Section 304(b) shall govern the exchange of
temporary Securities other than through the facilities of The Depository Trust
Company. If any such temporary Security is issued in global form, then such
temporary Global Security shall, unless otherwise provided therein, be delivered
to the London office of a depository or common depository (the "Common
Depository"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so

                                       27


<PAGE>   35


specified, as requested by the beneficial owner thereof; PROVIDED, HOWEVER,
that, unless otherwise specified in such temporary Global Security, upon such
presentation by the Common Depository, such temporary Global Security is
accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary Global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL as to the portion of such temporary Global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and PROVIDED FURTHER that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary Global Security only
in compliance with the requirements of Section 303.

      Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent. Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary Global
Security shall be delivered only outside the United States.

      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary Global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and CEDEL on such
Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit B-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications

                                       28


<PAGE>   36


made pursuant to this paragraph shall satisfy the certification requirements of
the preceding two paragraphs of this Section 304(b) and of the third paragraph
of Section 303 of this Indenture and the interests of the Persons who are the
beneficial owners of the temporary Global Security with respect to which such
certification was made will be exchanged for definitive Securities of the same
series and of like tenor on the Exchange Date or the date of certification if
such date occurs after the Exchange Date, without further act or deed by such
beneficial owners. Except as otherwise provided in this paragraph, no payments
of principal or interest owing with respect to a beneficial interest in a
temporary Global Security will be made unless and until such interest in such
temporary Global Security shall have been exchanged for an interest in a
definitive Security. Any interest so received by Euroclear and CEDEL and not
paid as herein provided shall be returned to the Trustee prior to the expiration
of two years after such Interest Payment Date in order to be repaid to the
Company.

      SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Company in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee, at its
Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided. In the event that the
Trustee shall cease to be Security Registrar, it shall have the right to examine
the Security Register at all reasonable times.

      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

      Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive. Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

                                       29


<PAGE>   37


      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate, or in any
indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; PROVIDED,
HOWEVER, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

      Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the
applicable Global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the

                                       30

Company shall appoint a successor depository with respect to such Global
Security or Securities. If (x) a successor depository for such Global Security
or Securities is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such unwillingness, inability or
ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable
series of Securities represented by such Global Security or Securities advise
DTC to cease acting as depository for such Global Security or Securities or (z)
the Company, in its sole discretion, determines at any time that all Outstanding
Securities (but not less than all) of any series issued or issuable in the form
of one or more Global Securities shall no longer be represented by such Global
Security or Securities, then the Company shall execute, and the Trustee shall
authenticate and deliver definitive Securities of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such Global Security or Securities. If any beneficial owner of an
interest in a permanent global Security is otherwise entitled to exchange such
interest for Securities of such series and of like tenor and principal amount of
another authorized form and denomination, as specified as contemplated by
Section 301 and PROVIDED that any applicable notice provided in the permanent
Global Security shall have been given, then without unnecessary delay but in any
event not later than the earliest date on which such interest may be so
exchanged, the Company shall execute, and the Trustee shall authenticate and
deliver definitive Securities in aggregate principal amount equal to the
principal amount of such beneficial owner's interest in such permanent Global
Security. On or after the earliest date on which such interests may be so
exchanged, such permanent Global Security shall be surrendered for exchange by
DTC or such other depository as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose;
PROVIDED, HOWEVER, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities to be
redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and PROVIDED
FURTHER that no Bearer Security delivered in exchange for a portion of a
permanent Global Security shall be mailed or otherwise delivered to any location
in the United States. If a Registered Security is issued in exchange for any
portion of a permanent Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent Global
Security is payable in accordance with the provisions of this Indenture.

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

                                       31


<PAGE>   39


      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company 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 Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

      The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, PROVIDED that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

      SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Company, together with, in proper cases, such
security or indemnity as may be required by the Company or the Trustee to save
each of them or any agent of either of them harmless, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

      If there shall be delivered to the Company and to the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security or
coupon, and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen

                                       32


<PAGE>   40


Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and principal amount, containing identical
terms and provisions and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen coupon appertains.

      Notwithstanding the provisions of the previous two paragraphs, in case any
such mutilated, destroyed, lost or stolen Security or coupon has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; PROVIDED, HOWEVER, that payment of principal of (and premium or Make-
Whole Amount, if any), and any interest on, Bearer Securities shall, except as
otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

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

      Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon 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 and their
coupons, if any, 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 or coupons.

      SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that 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 at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; PROVIDED, HOWEVER, that each
installment of interest on

                                       33


<PAGE>   41


any Registered Security may at the Company's option be paid by (i) mailing a
check for such interest, payable to or upon the written order of the Person
entitled thereto pursuant to Section 308, to the address of such Person as it
appears on the Security Register or (ii) transfer to an account maintained by
the payee located inside the United States.

      Unless otherwise provided as contemplated by Section 301 with respect to
the Securities of any series, payment of interest may be made, in the case of a
Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

      Unless otherwise provided as contemplated by Section 301, every permanent
global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case may be,
with respect to that portion of such permanent global Security held for its
account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

      In case a Bearer Security of any series is surrendered in exchange for a
Registered Security of such series after the close of business (at an office or
agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that 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 registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Company shall deposit with the Trustee an amount of money in the currency
      or currencies, currency unit or units or composite currency or currencies
      in which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series)

                                       34


<PAGE>   42


      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 on or prior to the date of the proposed payment, such
      money when deposited to be held in trust for the benefit of the Persons
      entitled to such Defaulted Interest as in this clause provided. Thereupon
      the Trustee shall fix a Special Record Date for the payment of such
      Defaulted Interest which shall be not more than 15 days and not less than
      10 days prior to the date of the proposed payment and not less than 10
      days after the receipt by the Trustee of the notice of the proposed
      payment. The Trustee shall promptly notify the Company of such Special
      Record Date and, in the name and at the expense of the Company, shall
      cause notice of the proposed payment of such Defaulted Interest and the
      Special Record Date therefor to be mailed, first-class postage prepaid, to
      each Holder of Registered Securities of such series at his address as it
      appears in the Security Register not less than 10 days prior to such
      Special Record Date. The Trustee may, in its discretion, in the name and
      at the expense of the Company, cause a similar notice to be published at
      least once in an Authorized Newspaper in each Place of Payment, but such
      publications shall not be a condition precedent to the establishment of
      such Special Record Date. Notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor having been mailed as
      aforesaid, such Defaulted Interest shall be paid to the Persons in whose
      names the Registered 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). In case a Bearer Security of any series is
      surrendered at the office or agency in a Place of Payment for such series
      in exchange for a Registered Security of such series after the close of
      business at such office or agency on any Special Record Date and before
      the opening of business at such office or agency on the related proposed
      date for payment of Defaulted Interest, such Bearer Security shall be
      surrendered without the coupon relating to such proposed date of payment
      and Defaulted Interest will not be payable on such proposed date of
      payment in respect of the Registered Security issued in exchange for such
      Bearer Security, but will be payable only to the Holder of such coupon
      when due in accordance with the provisions of this Indenture.

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

      Subject to the foregoing provisions of this Section and Section 305, 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
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium or Make-Whole Amount, if any),
and (subject to Sections 305 and 307) interest on, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary. All such payments so
made to any such Person, or upon such Person's order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for money payable upon any such Security.

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

      No Holder of any beneficial interest in any Global Security held on its
behalf by a depository shall have any rights under this Indenture with respect
to such Global Security and such depository shall be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

      Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depository, as a Holder, with respect to
such Global Security or impair, as between such depository and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such Global Security.

      SECTION 309. CANCELLATION. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, conversion or
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 any such Securities and coupons and Securities and coupons
surrendered directly to the Trustee for any such purpose shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to

                                       36


<PAGE>   44


any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. Cancelled Securities and coupons held by
the Trustee shall be destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Company, unless the Trustee is otherwise
directed by a Company Order.

      SECTION 310. COMPUTATION OF INTEREST. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.


                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

      SECTION 401. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall
upon Company Request cease to be of further effect with respect to any series of
Securities specified in such Company Request (except as to any surviving rights
of registration of transfer or exchange of Securities of such series herein
expressly provided for), and the Trustee, upon receipt of a Company Order, and
at the expense of the Company, shall execute instruments in form and substance
satisfactory to the Trustee and the Company acknowledging satisfaction and
discharge of this Indenture as to such series when

                  (1)   either

                  (A) all Securities of such series theretofore authenticated
            and delivered and all coupons, if any, appertaining thereto (other
            than (i) coupons appertaining to Bearer Securities surrendered for
            exchange for Registered Securities and maturing after such exchange,
            whose surrender is not required or has been waived as provided in
            Section 305, (ii) Securities and coupons of such series which have
            been destroyed, lost or stolen and which have been replaced or paid
            as provided in Section 306, (iii) coupons appertaining to Securities
            called for redemption and maturing after the relevant Redemption
            Date, whose surrender has been waived as provided in Section 1106,
            and (iv) Securities and coupons of such series for whose payment
            money has theretofore been deposited in trust or segregated and held
            in trust by the Company and thereafter repaid to the Company or
            discharged from such trust, as provided in Section 1003) have been
            delivered to the Trustee for cancellation; or

                  (B) all Securities of such series and, in the case of (i) or
            (ii) below, any coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation

                        (i)   have become due and payable, or

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

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

            and the Company, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for the purpose an amount in the currency or
            currencies, currency unit or units or composite currency or
            currencies in which the Securities of such series are payable,
            sufficient to pay and discharge the entire indebtedness on such
            Securities and such coupons not theretofore delivered to the Trustee
            for cancellation, for principal (and premium or Make-Whole Amount,
            if any) and interest to the date of such deposit (in the case of
            Securities which have become due and payable) or to the Stated
            Maturity or Redemption Date, as the case may be;

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

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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

      SECTION 402. APPLICATION OF TRUST FUNDS. Subject to the provisions of the
last paragraph of Section 1003, all money deposited with the Trustee pursuant to
Section 401 shall be held in trust and applied by it, in accordance with the

either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the

                                       38


<PAGE>   46


Persons entitled thereto, of the principal (and premium or Make-Whole Amount, if
any), and any interest for whose payment such money has been deposited with or
received by the Trustee, but such money need not be segregated from other funds
except to the extent required by law.


                             ARTICLE FIVE - REMEDIES

      SECTION 501. EVENTS OF DEFAULT. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not 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):

                  (1) default in the payment of any interest on any Security of
      that series or of any coupon appertaining thereto, when such interest or
      coupon becomes due and payable, and continuance of such default for a
      period of 30 days; or

                  (2) default in the payment of the principal of (or premium or
      Make-Whole Amount, if any, on) any Security of that series when it becomes

      and as due by the terms of any Security of that series; or

                  (4) default in the performance, or breach, of any covenant or
      warranty of the Company in this Indenture with respect to any Security of
      that series (other than a covenant or warranty a default in whose
      performance or whose breach is elsewhere in this Section specifically
      dealt with), and continuance of such default or breach for a period of 60
      days after there has been given, by registered or certified mail, to the
      Company by the Trustee or to the Company 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; or

                  (5) default under any bond, debenture, note, mortgage,
      indenture or instrument under which there may be issued or by which there
      may be secured or evidenced any indebtedness for money borrowed by the
      Company (or by any Subsidiary, the repayment of which the Company has
      guaranteed or for which the Company is directly responsible or liable as
      obligor or guarantor), having an aggregate principal amount outstanding of
      at least $25,000,000, whether such indebtedness now exists or shall
      hereafter be created, which default shall have resulted in such
      indebtedness becoming or being declared due and payable prior to the date
      on which it would otherwise have become due and payable, without such
      indebtedness having been

                                       39


<PAGE>   47


      discharged, or such acceleration having been rescinded or annulled, within
      a period of 10 days after there shall have been given, by registered or
      certified mail, to the Company by the Trustee or to the Company and the
      Trustee by the Holders of at least 10% in principal amount of the
      Outstanding Securities of that series a written notice specifying such
      default and requiring the Company to cause such indebtedness to be
      discharged or cause such acceleration to be rescinded or annulled and
      stating that such notice is a "Notice of Default" hereunder; or

                  (6)   the Company or any Significant Subsidiary pursuant to 
      or within the meaning of any Bankruptcy Law:

                        (A)   commences a voluntary case,

                        (B)   consents to the entry of an order for relief
            against it in an involuntary case,

                        (C)   consents to the appointment of a Custodian of it 
            or for all or substantially all of its property, or

                        (D)   makes a general assignment for the benefit of its
            creditors; or

                  (7) a court of competent jurisdiction enters an order or
      decree under any Bankruptcy Law that:

                        (A)   is for relief against the Company or any 
            Significant Subsidiary in an involuntary case,

                        (B)   appoints a Custodian of the Company or any 
            Significant Subsidiary or for all or substantially all of either of 
            its property, or

                        (C)   orders the liquidation of the Company or any
            Significant Subsidiary, and the order or decree remains unstayed and
            in effect for 90 days; or

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

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

      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

                                       40


<PAGE>   48


continuing, then and 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 (or, if Securities of that Series are Original
Issue Discount Securities or Indexed Securities, such portion of the principal
as may be specified in the terms thereof) of all the Securities of that series
to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by the Holders), and upon any such declaration such
principal or specified portion thereof 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 Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration of acceleration and its
consequences if:

                  (1) the Company has paid or deposited with the Trustee a sum
      sufficient to pay in the currency, currency unit or composite currency in
      which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series):

                        (A) all overdue installments of interest on all 
            Outstanding Securities of that series and any related coupons,

                        (B) the principal of (and premium or Make-Whole Amount,
            if any, on) any Outstanding Securities of that series which have
            become due otherwise than by such declaration of acceleration and
            interest thereon at the rate or rates borne by or provided for in
            such Securities,

                        (C) to the extent that payment of such interest is
            lawful, interest upon overdue installments of interest at the rate
            or rates borne by or provided for 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 nonpayment of the principal of (or premium or
      Make-Whole Amount, if any) or interest on Securities of that series which
      have become due solely by such declaration of acceleration, have been
      cured or waived as provided in Section 513.

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

      SECTION 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY 
TRUSTEE.  The Company covenants that if:

                  (1) default is made in the payment of any installment of
      interest on any Security of any series and any related coupon when such
      interest becomes due and payable and such default continues for a period
      of 30 days, or

                  (2) default is made in the payment of the principal of (or 
      premium or Make-Whole Amount, if any, on) any Security of any series at 
      its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue
installments of interest at the rate or rates borne by or provided for 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 the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

      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 and any
related coupons 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 the pendency of
any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Securities or the property of the
Company or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities of any series shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
overdue principal, premium or Make-Whole Amount, if any, or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise:

                                       42


<PAGE>   50


                        (i) to file and prove a claim for the whole amount, or
      such lesser amount as may be provided for in the Securities of such
      series, of principal (and premium or Make-Whole Amount, if any) and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

                        (ii) 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 of Securities of such series and coupons 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 to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

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

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

      SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES
OR COUPONS. All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or coupons 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 and
coupons 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 premium or Make-Whole Amount, if any) or
interest, upon presentation of the Securities or coupons, or

                                       43


<PAGE>   51


both, as the case may be, 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 and any 
      predecessor Trustee under Section 606;

            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, 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 aggregate amounts due and payable on such
      Securities and coupons for principal (and premium or Make-Whole Amount, if
      any) and interest, respectively; and

            THIRD: To the payment of the remainder, if any, to the Company.

      SECTION 507. LIMITATION ON SUITS. No Holder of any Security of any series
or any related coupon 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 25% 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 reasonably 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

                                       44


<PAGE>   52


Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

      SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
OR MAKE-WHOLE AMOUNT, IF ANY, AND INTEREST. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right
which is absolute and unconditional to receive payment of the principal of (and
premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (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 of a Security or coupon 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, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, 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 or coupons in the last paragraph of Section 306, no right or
remedy herein conferred upon or reserved to the Trustee or to the Holders of
Securities or coupons is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      SECTION 511. DELAY OR OMISSION NOT WAIVER. No delay or omission of the
Trustee or of any Holder of any Security or coupon 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 of Securities or coupons, as the
case may be.

      SECTION 512. CONTROL BY HOLDERS OF SECURITIES. The Holders of not less
than 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

                                       45


<PAGE>   53


                  (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) the Trustee need not take any action which might involve
      it in personal liability or be unduly prejudicial to the Holders of
      Securities of such series not joining therein.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

      SECTION 513. WAIVER OF PAST DEFAULTS. The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may on
behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

                  (1) in the payment of the principal of (or premium or 
      Make-Whole Amount, if any) or interest on any Security of such series or 
      any related coupons, or

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

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

      SECTION 514. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

      SECTION 515. UNDERTAKING FOR COSTS. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, 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 or omitted by it as

                                       46


<PAGE>   54


Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium or Make-Whole Amount, if any) or interest on any
Security on or after the respective Stated Maturities expressed in such Security
(or, in the case of redemption, on or after the Redemption Date).


                            ARTICLE SIX - THE TRUSTEE

      SECTION 601. NOTICE OF DEFAULTS. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking fund installment with respect to the Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interests of the Holders of the Securities and coupons
of such series; and PROVIDED FURTHER that in the case of any default or breach
of the character specified in Section 501(4) with respect to the Securities and
coupons of such series, no such notice to Holders shall be given until at least
60 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 the Securities of such series.

      SECTION 602. CERTAIN RIGHTS OF TRUSTEE. Subject to the provisions of TIA
Section 315(a) through 315(d):

                  (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, coupon 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 Company mentioned herein
      shall be sufficiently evidenced by a Company Request or Company Order
      (other than delivery of any Security, together with any coupons
      appertaining thereto, to the Trustee for authentication and delivery
      pursuant to Section 303 which shall be sufficiently

                                       47


<PAGE>   55


      evidenced as provided therein) and any resolution of the Board of 
      Directors may 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;

                  (4) the Trustee may consult with counsel and the written
      advice of such counsel or any Opinion of Counsel shall be full and
      complete authorization and protection in respect of any action taken,
      suffered or omitted by it hereunder in good faith and in reliance thereon;

                  (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 of Securities of any series or any related
      coupons pursuant to this Indenture, unless such Holders shall have offered
      to the Trustee security or indemnity reasonably satisfactory to the
      Trustee 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, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; PROVIDED that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the
      Company, relevant to the facts or matters that are the subject of its
      inquiry, personally or by agent or attorney;

                  (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; and


                                       48


<PAGE>   56


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

      The Trustee shall not be required 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.

      Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

      SECTION 603. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES. The
recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Company, 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 coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

      SECTION 604. MAY HOLD SECURITIES. The Trustee, any Paying Agent, Security
Registrar, Authenticating Agent or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Securities
and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with
the Company with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar, Authenticating Agent or such other agent.

      SECTION 605. 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 with the Company.

      SECTION 606. COMPENSATION AND REIMBURSEMENT. The Company agrees:

                  (1) to pay to the Trustee from time to time reasonable
      compensation 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 each of the Trustee and any predecessor Trustee upon its request
      for all reasonable expenses, disbursements and advances incurred or made
      by the Trustee in accordance

                                       49


<PAGE>   57


      with any provision of this Indenture (including the reasonable
      compensation and the reasonable expenses and disbursements of its agents
      and counsel), except any such expense, disbursement or advance as may be
      attributable to its negligence or bad faith; and

                  (3) to indemnify each of the Trustee and any predecessor
      Trustee for, and to hold it harmless against, any loss, liability or
      expense incurred without negligence or bad faith on its part, arising out
      of or in connection with the acceptance or administration of the trust 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.

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(7) or Section 501(8), 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.

      As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest on particular Securities or any coupons.

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

      SECTION 607. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000. If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee 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. Neither the Company nor any
Person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as Trustee.

      SECTION 608. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

                                       50


<PAGE>   58


            (b) The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If an instrument of acceptance by a successor Trustee shall not have
been delivered to the Trustee within 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.

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

            (d) If at any time:

                  (1) the Trustee shall fail to comply with the provisions of
      TIA Section 310(b) after written request therefor by the Company or by any
      Holder of a Security 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 607
      and shall fail to resign after written request therefor by the Company or
      by any Holder of a Security who has been a bona fide Holder of a Security
      for at least six months, 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, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security 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.

            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series). If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities
of

                                       51


<PAGE>   59


such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities and
accepted appointment in the manner hereinafter provided, any Holder of a
Security 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 Securities of such series.

            (f) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided for notices to the Holders of Securities 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 609. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. (a) 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 Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company 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 nevertheless to its claim, if any, provided for in
Section 606.

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto,
pursuant to Article Nine hereof, 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

                                       52


<PAGE>   60


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 Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 609, as the case may be.

            (d) 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 610. 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 of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons 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 or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. APPOINTMENT OF AUTHENTICATING AGENT. At any time when any of
the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents 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 or
repayment thereof, 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. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which

                                       53


<PAGE>   61


instrument shall be promptly furnished to the Company. 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 Company and shall at all times be a bank or trust company or
corporation organized and doing business and in good standing under the laws of
the United States of America or of any state 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 authorities. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid 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. In case 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 such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

      An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. 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 for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

      The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation including reimbursement of its reasonable expenses for
its services under this Section.

<PAGE>   62


      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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

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

      SECTION 612. CERTAIN DUTIES AND RESPONSIBILITIES OF THE TRUSTEE.

      (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

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

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

      (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.


                                       55


<PAGE>   63


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

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

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

            (3) the Trustee shall not be liable with respect to any action taken
      or omitted to be taken by it in good faith in accordance with the
      direction of the Holders of a majority in principal amount of the
      Outstanding Securities of any series relating to the time, method and
      place of conducting any proceeding for any remedy available to the
      Trustee, or exercising any trust or power conferred upon the Trustee,
      under this Indenture with respect to the Securities of such series; and

            (4) 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.

      (d) 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
612.

       ARTICLE SEVEN - HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

      SECTION 701. DISCLOSURE OF NAMES AND ADDRESSES OF HOLDERS. Every Holder of
Securities or coupons, by receiving and holding the same, agrees with the

held accountable by reason of the disclosure of any information as to the names
and addresses of the Holders of Securities in accordance with TIA Section 312,

within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time

PROVIDED, HOWEVER, that, so long as the Trustee is the Security Registrar, no

       ARTICLE EIGHT - CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

      SECTION 801. CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES, LEASES AND
CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS. The Company may consolidate
with, or sell, lease or convey all or substantially all of its assets to, or
merge with or into any other corporation, PROVIDED that in any such case, (1)
either the Company shall be the continuing corporation, or the successor
corporation shall be a corporation organized and existing under the laws of the
United States or a State thereof and such successor corporation shall expressly
assume the due and punctual payment of the principal of (and premium or
Make-Whole Amount, if any) and any interest on all of the Securities, according

such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein as the party of the first part, and the predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

      In case of any such consolidation, merger, sale, lease or conveyance, such
changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

      SECTION 803. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.

                  (2) to add to the covenants of the Company 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
      Company; or

                  (3) to add any additional Events of Default for the benefit of

      for the benefit of such series); PROVIDED, HOWEVER, that in respect of any
      such additional Events of Default such supplemental indenture may provide
      for a particular period of grace after default (which period may be
      shorter or longer than that allowed in the case of other defaults) or may
      provide for an immediate enforcement upon such default or may limit the
      remedies available to the Trustee upon such default or may limit the right
      of the Holders of a majority in aggregate principal amount of that or
      those series of Securities to which such additional Events of Default
      apply to waive such default; or

                  (4) to add to or change any of the provisions of this 
      Indenture to provide that Bearer Securities may be registrable as to

      prior to the execution of such supplemental indenture which is entitled to
      the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
      and any related coupons 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; 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

      with the provisions of this Indenture, provided such provisions shall not
      adversely affect the interests of the Holders of Securities of any series
      or any related coupons in any material respect; or

                  (10) to supplement any of the provisions of this Indenture to
      such extent as shall be necessary to permit or facilitate the defeasance
      and discharge of any series of Securities pursuant to Sections 401, 1402
      and 1403; PROVIDED that any such action shall not adversely affect the
      interests of the Holders of Securities of such series and any related
      coupons or any other series of Securities in any material respect; or

                  (11) to make provisions with respect to Holders' rights of
      conversion with respect to any series of Securities pursuant to Articles
      Seventeen.

      SECTION 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS. With the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Securities affected by such supplemental indenture, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by or pursuant to a Board Resolution, and the

                                       60

consent of the Holder of each Outstanding Security affected thereby:

                  (1) change the Stated Maturity of the principal of (or premium
      or Make-Whole Amount, if any, on) or any installment of principal of or
      interest on, any Security; or reduce the principal amount thereof or the
      rate or amount of interest thereon, or any premium or Make-Whole Amount
      payable upon the redemption thereof, or reduce the amount of the principal
      of an Original Issue Discount Security that would be due and payable upon
      a declaration of acceleration of the Maturity thereof pursuant to Section
      502 or the amount thereof provable in bankruptcy pursuant to Section 504,
      or adversely affect any right of repayment at the option of the Holder of

      enforcement of any such payment on or after the Stated Maturity thereof
      (or, in the case of redemption or repayment at the option of the Holder,
      on or after the Redemption Date or the Repayment Date, as the case may
      be), or (if Securities of such series are convertible) adversely affect
      the right of the Holder to convert any Security as provided in Article
      Seventeen, or modify the provisions of this Indenture with respect to the
      subordination of the Securities in a manner materially adverse to the
      Holders; 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

                  (3) modify any of the provisions of this Section, Section 513
      or Section 1009, except to increase the required percentage to effect such
      action 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 902 and Section 1009, or the deletion of this proviso, in
      accordance with the requirements of Sections 609(b) and 901(11).

exchange for Outstanding Securities of such series.


                             ARTICLE TEN - COVENANTS

      SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM OR MAKE-WHOLE AMOUNT, IF ANY;
AND INTERESt. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium or Make-Whole Amount, if any) and interest on the Securities of
that series in accordance with the terms of such series of Securities, any
coupons appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any
interest due on Bearer Securities on or before Maturity shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are

                                       62


<PAGE>   70


evidenced thereby as they severally mature. Unless otherwise specified with
respect to Securities of any series pursuant to Section 301, at the option of
the Company, all payments of principal may be paid by check to the registered
Holder of the Registered Security or other person entitled thereto against
surrender of such Security.

      SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY. If Securities of a series
are issuable only as Registered Securities, the Company shall 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 or
conversion, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company will
maintain: (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of that
series may be surrendered for exchange, where notices and demands to or upon the
Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion in the circumstances
described in the following paragraph (and not otherwise); (B) subject to any
laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment;
PROVIDED, HOWEVER, that if the Securities of that series are listed on any stock
exchange located outside the United States and such stock exchange shall so
require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States, as the case may
be, so long as the Securities of that series are listed on such exchange; and
(C) subject to any laws or regulations applicable thereto, in a Place of Payment
for that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment or conversion at the offices specified in the Security,
in London, England, and the Company hereby appoints the same as its agent to
receive such respective presentations, surrenders, notices and demands, and the
Company hereby appoints the Trustee its agent to receive all such presentations,
surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or Make-Whole Amount or interest
on Bearer Securities shall

                                       63


<PAGE>   71


be made at any office or agency of the Company in the United States or by check
mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; PROVIDED, HOWEVER, that, if
the Securities of a series are payable in Dollars, payment of principal of and
any premium or Make-Whole Amount and interest on any Bearer Security shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or Make-Whole Amount, or interest, as the case may be,
at all offices or agencies outside the United States maintained for the purpose
by the Company in accordance with this Indenture, is illegal or effectively
precluded by exchange controls or other similar restrictions.

      The Company may 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 of such purposes, and may from time to time rescind
such designations; PROVIDED, HOWEVER, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency. Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Company hereby designates as a Place of Payment for each series of
Securities the office or agency of the Company in the Borough of Manhattan, The
City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

      Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

      SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If the
Company shall at any time act as its own Paying Agent with respect to any series
of any Securities and any related coupons, it will, on or before each due date
of the principal of (and premium or Make-Whole Amount, if any), 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 in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and will promptly notify the Trustee of its action or failure so to
act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities and any related coupons, it will, on or before each due date of
the principal of (and

                                       64

series, deposit with a Paying Agent a sum (in the currency or currencies,
currency unit or units or composite currency or currencies described in the
preceding paragraph) sufficient to pay the principal (and premium or Make-Whole
Amount, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or Make-Whole
Amount, if any, or interest and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee 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) hold all sums held by it for the payment of principal of
      (and premium or Make-Whole Amount, if any) or interest on Securities in
      trust for the benefit of the Persons entitled thereto until such sums
      shall be paid to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Company (or
      any other obligor upon the Securities) in the making of any such payment
      of principal (and premium or Make-Whole Amount, if any) or interest on the
      Securities of that series; and

                  (3) at any time during the continuance of any such default
      upon the written request of the Trustee, forthwith pay to the Trustee all
      sums so held in trust by such Paying Agent.

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

      Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on any Security of any series and remaining unclaimed for two
years after such principal (and premium or Make- Whole Amount, if any) or
interest has become due and payable shall be paid to the Company upon Company
Request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment of such principal of (and premium
or Make-Whole Amount, if any) or interest on any Security, without interest
thereon, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee

                                       65


<PAGE>   73


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 Company cause to be published once, in an Authorized Newspaper,
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
Company.

cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, all material rights (by articles of
incorporation, by-laws and statute) and material franchises; PROVIDED, HOWEVER,

discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; PROVIDED, HOWEVER, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

Trustee, within 120 days after the end of each fiscal year, a brief certificate
from the principal executive officer, principal financial officer or principal
accounting officer as to his or her knowledge of the Company's compliance with

      SECTION 1009. WAIVER OF CERTAIN COVENANTS. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1009, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall

portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

amount thereof to be redeemed.

      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 Security redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

      SECTION 1104. NOTICE OF REDEMPTION. Notice of redemption shall be given in
the manner provided in Section 106, not less than 30 days nor more than 60 days
prior to the Redemption Date, unless a shorter period is specified by the terms
of such series established pursuant to Section 301, to each Holder of Securities
to be redeemed, but failure to give such notice in the manner herein provided to
the Holder of any Security designated for redemption as a whole or in part, or
any defect in the notice to any such Holder, shall not affect the validity of
the proceedings for the redemption of any other such Security or portion
thereof.

      Any notice that is mailed to the Holders of Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives the notice.

      All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price, accrued interest to the Redemption
      Date payable as provided in Section 1106, if any,

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

                  (4) in case any Security is to be redeemed in part only, the
      notice which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the holder will receive,
      without a charge, a new Security or Securities of authorized denominations
      for the principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price and
      accrued interest to the Redemption Date payable as provided in Section
      1106, if any, will become due and payable upon each such Security, or the
      portion thereof, to be redeemed and, if applicable, that interest thereon
      shall cease to accrue on and after said date,


                                       68


<PAGE>   76


                  (6) the Place or Places of Payment where such Securities,
      together in the case of Bearer Securities with all coupons appertaining
      thereto, if any, maturing after the Redemption Date, are to be surrendered
      for payment of the Redemption Price and accrued interest, if any, or for
      conversion,

                  (7) that the redemption is for a sinking fund, if such is the
      case,

                  (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing coupon or coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Company, the Trustee for such series and any Paying
      Agent is furnished,

                  (9) if Bearer Securities of any series are to be redeemed and
      any Registered Securities of such series are not to be redeemed, and if
      such Bearer Securities may be exchanged for Registered Securities not
      subject to redemption on this Redemption Date pursuant to Section 305 or
      otherwise, the last date, as determined by the Company, on which such
      exchanges may be made,

                  (10) the CUSIP number of such Security, if any, and

                  (11) if applicable, that a Holder of Securities who desires to
      convert Securities for redemption must satisfy the requirements for
      conversion contained in such Securities, the then existing conversion
      price or rate, the place or places where such Securities may be
      surrendered for conversion, and the date and time when the option to
      convert shall expire.

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

      SECTION 1105. DEPOSIT OF REDEMPTION PRICE. On or prior to any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, which it may not do in the case
of a sinking fund payment under Article Twelve, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.


                                       69


<PAGE>   77


      If any Securities called for redemption are converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Security shall be paid to the Company upon Company
Request or, if then held by the Company, shall be discharged from such trust.


      SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE. Notice of redemption
having been given as aforesaid, the Securities so to be redeemed shall, on the
Redemption Date, become due and payable at the Redemption Price therein
specified in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) (together with accrued interest, if any, to the Redemption Date),
and from and after such date (unless the Company shall default in the payment of
the Redemption Price and accrued interest) such Securities shall, if the same
were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be redeemed, except to the extent
provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest, if
any, to the Redemption Date; PROVIDED, HOWEVER, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and PROVIDED FURTHER that, except as otherwise provided with
respect to Securities convertible into the Company's Common Stock or Preferred
Stock, installments of interest on Registered Securities whose Stated Maturity
is on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; PROVIDED, HOWEVER, that interest
represented by coupons shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.


                                       70


<PAGE>   78


      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium or Make-Whole Amount, if any)
shall, until paid, bear interest from the Redemption Date at the rate borne by
the Security.

      SECTION 1107. SECURITIES REDEEMED IN PART. Any Registered Security which
is to be redeemed only in part (pursuant to the provisions of this Article or of
Article Twelve) shall be surrendered at a Place of Payment therefor (with, if
the Company or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Company and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge a new Security or Securities of
the same series, 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. If a Global Security is so
surrendered, the Company shall execute and the Trustee shall authenticate and
deliver to the depository, without service charge, a new Global Security in a
denomination equal to and in exchange for the unredeemed portion of the
principal of the Global Security so surrendered.


                         ARTICLE TWELVE - 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 a
series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series 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 of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory 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 of any series as provided for by the
terms of Securities of such series.

      SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES. The
Company may, in satisfaction of all or any part of any mandatory sinking fund
payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; PROVIDED that such Securities so delivered or applied as a credit have
not been previously so credited. Such

                                       71


<PAGE>   79


Securities shall be received and credited for such purpose by the Trustee at the
applicable Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

      SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND. Not less than 60
days prior to each sinking fund payment date for Securities of any series, the
Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Company shall thereupon be obligated to pay the amount
therein specified. Not less than 30 days before 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
Company 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 1106 and 1107.


              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

      SECTION 1301. APPLICABILITY OF ARTICLE. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

      SECTION 1302. REPAYMENT OF SECURITIES. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless
otherwise provided in the terms of such Securities, be repaid at a price equal
to the principal amount thereof, together with interest, if any, thereon accrued
to the Repayment Date specified in or pursuant to the terms of such Securities.
The Company covenants that on or prior to the Repayment Date it will deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay the principal (or, if so provided by the terms of
the Securities of any series, a percentage of the principal) of, and

                                       72


<PAGE>   80


(except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

      SECTION 1303. EXERCISE OF OPTION. Securities of any series subject to
repayment at the option of the Holders thereof will contain an "Option to Elect
Repayment" form on the reverse of such Securities. In order for any Security to
be repaid at the option of the Holder, the Trustee must receive at the Place of
Payment therefor specified in the terms of such Security (or at such other place
or places of which the Company shall from time to time notify the Holders of
such Securities) not earlier than 60 days nor later than 30 days prior to the
Repayment Date (1) the Security so providing for such repayment together with
the "Option to Elect Repayment" form on the reverse thereof duly completed by
the Holder (or by the Holder's attorney duly authorized in writing) or (2) a
telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in the United States setting
forth the name of the Holder of the Security, the principal amount of the
Security, the principal amount of the Security to be repaid, the CUSIP number,
if any, or a description of the tenor and terms of the Security, a statement
that the option to elect repayment is being exercised thereby and a guarantee
that the Security to be repaid, together with the duly completed form entitled
"Option to Elect Repayment" on the reverse of the Security, will be received by
the Trustee not later than the fifth Business Day after the date of such
telegram, telex, facsimile transmission or letter; PROVIDED, HOWEVER, that such
telegram, telex, facsimile transmission or letter shall only be effective if
such Security and form duly completed are received by the Trustee by such fifth
Business Day. If less than the entire principal amount of such Security is to be
repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part. Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Company.

      SECTION 1304. WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void.

                                       73


<PAGE>   81


Upon surrender of any such Security for repayment in accordance with such
provisions, together with all coupons, if any, appertaining thereto maturing
after the Repayment Date, the principal amount of such Security so to be repaid
shall be paid by the Company, together with accrued interest, if any, to the
Repayment Date; PROVIDED, HOWEVER, that coupons whose Stated Maturity is on or
prior to the Repayment Date shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and PROVIDED FURTHER that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Company shall default in the payment thereof) 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 Bearer Security surrendered for repayment shall not be accompanied
by all appurtenant coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable therefor as provided in Section
1302 an amount equal to the face amount of all such missing coupons, or the
surrender of such missing coupon or coupons may be waived by the Company and the
Trustee if there be furnished to them such security or indemnity as they may
require to save each of them and any Paying Agent harmless. If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of which a deduction shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted; PROVIDED, HOWEVER, that interest represented by coupons
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of those
coupons.

      If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

      SECTION 1305. SECURITIES REPAID IN PART. Upon surrender of any Registered
Security which is to be repaid in part only, the Company shall execute and the
Trustee shall authenticate and deliver to the Holder of such Security, without
service charge and at the expense of the Company, a new Registered Security or
Securities of the same series, of any authorized denomination specified by the
Holder, in an aggregate principal amount equal to and in exchange for the
portion of the principal of such Security so surrendered which is not to be
repaid.

              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

      SECTION 1401. APPLICABILITY OF ARTICLE: Company's Option to Effect
Defeasance or Covenant Defeasance. If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

      SECTION 1402. DEFEASANCE AND DISCHARGE. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 305, 306, 1002 and
1003, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Company may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such
Securities and any coupons appertaining thereto.

      SECTION 1403. COVENANT DEFEASANCE. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are

                                       75


<PAGE>   83


satisfied (hereinafter, "covenant defeasance"), and such Securities and any
coupons appertaining thereto shall thereafter be deemed to be not "Outstanding"
for the purposes of any direction, waiver, consent or declaration or Act of
Holders (and the consequences of any thereof) in connection with Sections 1004
to 1009, inclusive, or such other covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
coupons appertaining thereto, the Company may omit to comply with and shall have
no liability in respect of any term, condition or limitation set forth in any
such Section or such other covenant, whether directly or indirectly, by reason
of any reference elsewhere herein to any such Section or such other covenant or
by reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 501(4) or 501(8) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and any coupons appertaining thereto shall be
unaffected thereby.

      SECTION 1404. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

            (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) 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 and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) 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 of principal of (and premium or Make-Whole Amount, if any) and interest,
if any, on such Securities and any coupons appertaining thereto, money in an
amount, or (3) a combination thereof, in any case, in an amount, sufficient,
without consideration of any reinvestment of such principal and interest, 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 (or other qualifying
trustee) to pay and discharge, (i) the principal of (and premium or Make-Whole
Amount, if any) and interest, if any, on such Outstanding Securities and any
coupons appertaining thereto on the Stated Maturity of such principal or
installment of principal or interest and (ii) any mandatory sinking fund
payments or analogous payments applicable to such Outstanding Securities and any
coupons appertaining thereto on the day on which such payments are due and
payable in accordance with the terms of this Indenture and of such Securities
and any coupons appertaining thereto.


                                       76


<PAGE>   84


            (b) Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

            (c) No Event of Default or event which with notice or lapse of time
or both would become an Event of Default with respect to such Securities and any
coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit or, insofar as Sections 501(6) and 501(7) are concerned, at any
time during the period ending on the 91st day after the date of such deposit (it
being understood that this condition shall not be deemed satisfied until the
expiration of such period).

            (d) In the case of an election under Section 1402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling, or (ii) since the date of execution of this Indenture, there has been
a change in the applicable Federal income tax law, in either case to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Outstanding Securities and any coupons appertaining thereto will not recognize
income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance
had not occurred.

            (e) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

            (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company, with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

            (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

      SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium or Make-Whole Amount, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

      Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

      The Company 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 1404 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 such Outstanding Securities and any coupons
appertaining thereto.

      Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon Company Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the

                                       78

Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect a defeasance or covenant defeasance, as applicable, in
accordance with this Article.

Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding

or by having the signature of the Person executing the proxy witnessed or

Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

Securities of any Series shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of
votes on any vote by ballot taken thereat and affidavits by one or more persons
having knowledge of the fact, setting forth a copy of the notice of the meeting

copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.


                  ARTICLE SIXTEEN - SUBORDINATION OF SECURITIES

      SECTION 1601. AGREEMENT TO SUBORDINATE. Notwithstanding anything in this

Company covenants and agrees, and each Holder of a Security, by his acceptance
thereof, likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article, the Indebtedness represented by the

the Securities are hereby expressly made subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness.

      SECTION 1602. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC. In the event
of (a) any insolvency or bankruptcy case or Proceeding, or any receivership,
liquidation, reorganization or other similar case or Proceeding in connection
therewith, relative to the Company or to its creditors, as such, or to its
assets, or (b) any liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy, or (c) any assignment for the benefit of creditors or any other
marshaling of assets and liabilities of the Company, then and in any such event
specified in (a), (b) or (c) above (each such event, if any, herein sometimes
referred to as a "Proceeding")

            (1) the holders of Senior Indebtedness shall first be entitled to
      receive payment in full of all Obligations due or to become due on or in
      respect of all Senior Indebtedness, or provision shall be made for such
      payment in cash or cash equivalents or otherwise in a manner satisfactory
      to the holders of Senior Indebtedness, before the Holders of the
      Securities are entitled to receive any payment or distribution on account
      of principal of or premium, if any, or interest on or other Obligations in
      respect of the

                                       82


<PAGE>   90


      Securities or on account of any purchase, redemption or other acquisition
      of Securities by the Company or any Subsidiary (individually and
      collectively, a "Securities Payment"), and

            (2) any payment or distribution of assets of the Company of any kind
      or character, whether in cash, property or securities (other than Capital
      Stock or securities of the Company as reorganized or readjusted, or
      securities of the Company or any other corporation provided for by a plan
      of reorganization or readjustment, the payment of which is subordinate, at
      least to the extent provided in this Article Sixteen with respect to the
      Securities, to the payment in full, without diminution or modification by
      such plan, of all Senior Indebtedness), to which the Holders would be
      entitled except for the provisions of this Article Sixteen, shall be paid
      by the liquidating trustee or agent or other person making such a payment
      or distribution, directly to the holders of Senior Indebtedness) (or their
      representative(s) or trustee(s) acting on their behalf), ratably according
      to the aggregate amounts remaining unpaid on account of the principal of
      or interest on and other amounts due on the 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 to the holders of such Senior
      Indebtedness.

      In the event that, notwithstanding the foregoing provisions of this
Section 1601, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities (other than Capital Stock or securities
of the Company as reorganized or readjusted, or securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment, the

modification by such plan, of Senior Indebtedness), before all Senior
Indebtedness is paid in full or payment thereof provided for in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, such payment or distribution shall be held in trust for the
benefit of, and be paid over to, the holders of the Senior Indebtedness
remaining unpaid (or their representative(s) or trustee(s) acting on their
behalf), ratably as aforesaid, for application to the payment of such Senior
Indebtedness until such Senior Indebtedness shall have been paid in full, after
giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness.

another Person or the liquidation or dissolution of the Company following the
conveyance or transfer of all or substantially all of its properties and assets
as an entirety to another Person upon the terms and conditions set forth in
Article Eight shall not be deemed a Proceeding for the purposes of this Section
1602 if the Person formed by such consolidation or into which the Company is
merged or the Person which acquires by conveyance or transfer such properties
and assets as an entirety, as the case may be, shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions set
forth in Article Eight.

<PAGE>   91


      SECTION 1603. NO PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT. Anything in
this Indenture to the contrary notwithstanding, no payment on account of
principal of or redemption of, interest on or other amounts due on the
Securities, and no redemption, purchase, or other acquisition of the Securities,
shall be made by or on behalf of the Company (i) unless full payment of amounts
then due for principal and interest and of all other obligations then due on all
Senior Indebtedness has been made or duly provided for pursuant to the terms of
the instrument governing such Senior Indebtedness, (ii) if, at the time of such
payment, redemption, purchase or other acquisition, or immediately after giving
effect thereto, there shall exist under any Senior Indebtedness, or any
agreement pursuant to which any Senior Indebtedness is issued, any default,
which default shall not have been cured or waived and which default shall have
resulted in the full amount of such Senior Indebtedness being declared due and
payable or (iii) if, at the time of such payment, redemption, purchase or other
acquisition, the Trustee shall have received written notice from the holder or
holders of any Senior Indebtedness or their representative or representatives (a
"Payment Blockage Notice") that there exists under such Senior Indebtedness, or
any agreement pursuant to which such Senior Indebtedness is issued, any default,
which default shall not have been cured or waived, permitting the holders
thereof to declare the full amount of such Senior Indebtedness due and payable,
but only for the period (the "Payment Blockage Period") commencing on the date
of receipt of the Payment Blockage Notice and ending (unless earlier terminated
by notice given to the Trustee by the Holders of such Senior Indebtedness) on
the earlier of (A) the date on which such event of default shall have been cured
or waived or (B) 180 days from the receipt of the Payment Blockage Notice. Upon
termination of a Payment Blockage Period, payments on account of principal of or
interest on the Securities and redemptions, purchases or other acquisitions may
be made by or on behalf of the Company. Notwithstanding anything herein to the
contrary, (A) only one Payment Blockage Notice may be given during any period of
360 consecutive days with respect to the same event of default and any other
events of default on the same issue of Senior Indebtedness existing and known to
the person giving such notice at the time of such notice and (B) no new Payment
Blockage Period may be commenced by the holder or holders of the same issue of
Senior Indebtedness or their representative or representatives during any period
of 360 consecutive days unless all events of default which were the object of
the immediately preceding Payment Blockage Notice, and any other event of
default on the same issue of Senior Indebtedness existing and known to the
person giving such notice at the time of such notice, have been cured or waived.

      In the event that, notwithstanding the provisions of this Section 1603,
payments are made by or on behalf of the Company in contravention of the
provisions of this Section 1603, such payments shall be held by the Trustee, any
Paying Agent or the Holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the holders of Senior Indebtedness or
their representative or the trustee under the indenture or other agreement (if
any), pursuant to which any instruments evidencing any Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of all Senior Indebtedness remaining unpaid to the extent necessary
to pay all Senior Indebtedness in full in accordance with the terms of such
Senior Indebtedness, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

                                       84


<PAGE>   92


      The provisions of this Section shall not apply to any payment with respect
to which Section 1602 would be applicable.

      SECTION 1604. RELIANCE BY SENIOR INDEBTEDNESS ON SUBORDINATION PROVISIONS.
Each Holder of any Security by his acceptance thereof acknowledges and agrees
that the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration for each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in acquiring
and continuing to hold or in continuing to hold such Senior Indebtedness.

      SECTION 1605. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR INDEBTEDNESS.
Subject to the payment in full of all Obligations due or to become due on or in
respect of Senior Indebtedness, or the provision for such payment in cash or
cash equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness, the Holders of the Securities shall be subrogated to the extent of
the payments or distributions made to the holders of such Senior Indebtedness
pursuant to the provisions of this Article Sixteen to the rights of the holders
of such Senior Indebtedness to receive payments and distributions of cash,
property and securities applicable to the Senior Indebtedness until the
principal of and premium, if any, and interest on the Securities shall be paid
in full. For purposes of such subrogation, no payments or distributions to the
holders of the Senior Indebtedness of any cash, property or securities to which
the Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article Sixteen, and no payments over pursuant to the
provisions of this Article Sixteen to the holders of Senior Indebtedness by
Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

      SECTION 1606. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS. The provisions
of this Article Sixteen are and are intended solely for the purpose of defining
the relative rights of the Holders of the Securities on the one hand and the
holders of Senior Indebtedness on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Securities is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Securities, the obligation of the
Company, which is absolute and unconditional (and which, subject to the rights
under this Article Sixteen of the holders of Senior Indebtedness, is intended to
rank equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of and premium, if any, and interest on
the Securities as and when the same shall become due and payable in accordance
with their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to

                                       85


<PAGE>   93


the rights, if any, under this Article of the holders of Senior Indebtedness to
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

      SECTION 1607. TRUSTEE TO EFFECTUATE SUBORDINATION. Each Holder of a
Security by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate, as
between the Holders of the Securities and the holders of Senior Indebtedness,
the subordination provided in this Article Sixteen and appoints the Trustee his
attorney-in-fact for any and all such purposes, including, in the event of any
dissolution, winding up or liquidation or reorganization under any applicable
bankruptcy law of the Company (whether in bankruptcy, insolvency or receivership
Proceedings or otherwise), the timely filing of a claim for the unpaid balance
of such Holder's Securities in the form required in such Proceedings and the
causing of such claim to be approved. If the Trustee does not file a claim or
proof of debt in the form required in such Proceedings prior to 30 days before
the expiration of the time to file such claims or proofs, then the holders of
Senior Indebtedness, jointly, or their representatives shall have the right to
file an appropriate claim for and on behalf of the Holders and to demand, sue
for, collect, receive and receipt for the payments and distributions in respect
of the Securities which are required to be paid or delivered to the holders of
Senior Indebtedness as provided in this Article Sixteen and to take all such
other action in the name of the Holders or otherwise, as such holder of Senior
Indebtedness or representative thereof may determine to be necessary or
appropriate for the enforcement of the provisions of this Article Sixteen.

      SECTION 1608. NO WAIVER OF SUBORDINATION PROVISIONS. No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder or any representative or trustee
therefor, or by any non-compliance by the Company with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof any such holder
may have or be otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article Sixteen or the
obligations hereunder of the Holders of the Securities to the holders of Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii)
release any Person liable in any manner for the collection of Senior
Indebtedness and settle or compromise Senior Indebtedness (which, to the extent
so settled and compromised, shall be deemed to have been paid in full for all
purposes hereof); (iv) apply any amounts received to any liability of the
Company owing to holders of

                                       86


<PAGE>   94


Senior Indebtedness; and (v) exercise or refrain from exercising any rights
against the Company and any other Person.

      SECTION 1609. NOTICE TO TRUSTEE. The Company shall give prompt written
notice to the Trustee of any default or event of default with respect to any
Senior Indebtedness or of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Securities pursuant
to the provisions of this Article Sixteen. Notwithstanding the provisions of
this Article Sixteen or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment to or by the Trustee in respect of the Securities,
unless and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any representative or trustee
acting on their behalf; and, prior to the receipt of any such written notice,
the Trustee, subject to the provisions of Section 612, shall be entitled in all
respects to assume that no such facts exist; PROVIDED, HOWEVER, that if the
Trustee shall not have received the notice provided for in this Section at least
three Business Days prior to the date upon which by the terms hereof any money
may become payable for any purpose (including, without limitation, the payment
of the principal of and premium, if any, or interest on any Security), then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to the
purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within three Business Days
prior to such date. Nothing contained in this Article Sixteen or any other
Article of this Indenture or in any of the Securities shall prevent (a) the
Company, at any time except during the pendency of any Proceeding, or under the
conditions described in Section 1603, from making payments at any time in
respect of the Securities, or (b) the application by the Trustee of any money
deposited with it hereunder to the payment of or on account of the Securities,
or the retention thereof by any Holder, if the Trustee did not have notice, as
provided in this Section 1609, that such payment would have been prohibited by
the provisions of this Article Sixteen.

      Subject to the provisions of Section 612, 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 representative or trustee therefor)
to establish that such notice has been given by a holder of Senior Indebtedness
(or a trustee therefor). In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article Sixteen, 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 Sixteen, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

      SECTION 1610. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets of the Company referred to in
this Article Sixteen, the Trustee, subject to the provisions of Section 612, and
the Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which any Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

      SECTION 1611. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR INDEBTEDNESS.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness. Nothing contained in this Article Sixteen or elsewhere in
this Indenture, or in any of the Securities, shall prevent the application by
the Trustee of any moneys which were deposited with it hereunder, prior to its
receipt of written notice of facts which would prohibit such application, for
the purpose of the payment of or on account of the principal of or interest on,
the Securities unless, prior to the date on which such application is made by
the Trustee, the Trustee shall be charged with notice under Section 1609 hereof
of the facts which would prohibit the making of such application.

      SECTION 1612. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR INDEBTEDNESS;
PRESERVATION OF TRUSTEE'S RIGHTS. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article Sixteen with respect to
any Senior Indebtedness which may at any time be held by it, to the same extent
as any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder. Nothing in this Article
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 606.

      SECTION 1613. ARTICLE APPLICABLE TO PAYING AGENTS. In case at any time any
Paying Agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "Trustee" as used in this Article Sixteen
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; PROVIDED, HOWEVER, that Section 1612
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

                  ARTICLE SEVENTEEN - CONVERSION OF SECURITIES

      SECTION 1701. APPLICABILITY OF ARTICLE; CONVERSION PRIVILEGE AND 
CONVERSION PRICE.

      Securities of any series which are convertible shall be convertible in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of

                                       88


<PAGE>   96


any series) in accordance with this Article Seventeen. Subject to and upon
compliance with the provisions of this Article Seventeen, at any time during the
period specified in the Securities, at the option of the Holder thereof, any
Security or any portion of the principal amount thereof which is $1,000 or an
integral multiple of $1,000 may be converted at the principal amount thereof, or
of such portion thereof, into fully paid and nonassessable shares (calculated as
to each conversion to the nearest 1/100 of a share) of Common Stock of the
Company, at the Conversion Price, determined as hereinafter provided, in effect
at the time of conversion. In case a Security or portion thereof is called for
redemption, such conversion right in respect of the Security or portion so
called shall expire at the close of business on the Business Day immediately
preceding the Redemption Date, unless the Company defaults in making the payment
due upon redemption, in which case such conversion right shall terminate on the
date such default is cured.

      The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") of Securities of any series
shall be specified in such Securities. The Conversion Price shall be adjusted in
certain instances as provided in Section 1704.

      In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in paragraph (4) of Section 1704,
the Holder of each Security, upon the conversion thereof pursuant to this
Article Seventeen subsequent to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution and prior to
the effectiveness of the Conversion Price adjustment in respect of such
distribution pursuant to paragraph (4) of Section 1704, shall be entitled to
receive for each share of Common Stock into which such Security is converted,
the portion of the evidence of indebtedness, shares of Capital Stock or assets
so distributed applicable to one share of Common Stock; PROVIDED, HOWEVER, that,
at the election of the Company (whose election shall be evidenced by a Board
Resolution filed with the Trustee) with respect to all Holders so converting,
the Company may, in lieu of distributing to such Holder any portion of such
distribution not consisting of cash or securities of the Company, pay such
Holder an amount in cash equal to the fair market value thereof (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution filed with the Trustee). If any conversion
of a Security entitled to the benefits described in the immediately preceding
sentence occurs prior to the payment date for a distribution to holders of
Common Stock which the Holder of the Security so converted is entitled to
receive in accordance with the immediately preceding sentence, the Company may
elect (such election to be evidenced by a Board Resolution filed with the
Trustee) to distribute to such Holder a due bill for the evidences of
indebtedness, shares of Capital Stock or assets to which such Holder is so
entitled, provided that such due bill (i) meets any applicable requirements of
the principal national securities exchange or other market on which the Common
Stock is then traded, and (ii) requires payment or delivery of such evidences of
indebtedness or assets no later than the date of payment or delivery thereof to
holders of Common Stock receiving such distribution.

<PAGE>   97


      SECTION 1702.  EXERCISE OF CONVERSION PRIVILEGE.

      In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, duly endorsed or assigned to the
Company or in blank, at any office or agency maintained by the Company pursuant
to Section 1002, accompanied by written notice to the Company at such office or
agency that the Holder elects to convert such Security or, if less than the
entire principal amount thereof is to be converted, the portion thereof to be
converted and shall comply with any additional requirements set forth in such
Security. Securities surrendered for conversion during the period from the close
of business on any Regular Record Date next preceding any Interest Payment Date
to the opening of business on such Interest Payment Date shall (except for
Securities the Maturity of which is prior to such Interest Payment Date) be
accompanied by payment in New York Clearing House funds or other funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of Securities being surrendered
for conversion and such interest shall be paid on such Interest Payment Date as
provided in Section 307. Except as provided in the preceding sentence, no
payment or adjustment shall be made upon any conversion on account of any
interest accrued on the Securities surrendered for conversion or on account of
any dividends on the Common Stock issued upon conversion.

      The Company's delivery to the Holder of the fixed number of shares of the
Common Stock of the Company (and any cash in lieu of any fractional share of
Common Stock) into which the Security is convertible shall be deemed to satisfy
the Company's obligation to pay the principal amount of the Security and all
accrued interest and original issue discount that has not previously been paid.
The shares of Common Stock of the Company so delivered shall be treated as
issued first in payment of accrued interest and original issue discount and then
in payment of principal. Thus, accrued interest and original issue discount
shall be treated as paid, rather than canceled, extinguished or forfeited.

      Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1703.

      In the case of any Security which is converted in part only, as promptly
as practicable on or after the conversion date the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof
(or the Depositary in the case of a Global Security), at the expense of the
Company, a new Security or Securities, of authorized denominations in aggregate
principal amount equal to the unconverted portion of the principal amount of
such Security.

                                       90


<PAGE>   98


      SECTION 1703.  FRACTIONS OF SHARES.

      No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Security or Securities (or
specified portions thereof), the Company shall pay a cash adjustment (rounded to
the nearest cent) in respect of such fraction in an amount equal to the same
fraction of the Closing Price per share of the Common Stock on the day of
conversion (or, if such day is not a Trading Day, on the Trading Day immediately
preceding such day).

      SECTION 1704.  ADJUSTMENT OF CONVERSION PRICE.

      The Conversion Price shall be subject to adjustment from time to time as
follows:

                  (1) If the Company pays or makes a dividend or other
      distribution (a) on its Common Stock exclusively in Common Stock or (b) on
      any other class of Capital Stock of the Company, which dividend or
      distribution includes Common Stock of the Company, the Conversion Price in
      effect at the opening of business on the day following the date fixed for
      the determination of stockholders entitled to receive such dividend or
      other distribution (the "Dividend Record Date") shall be reduced by
      multiplying such Conversion Price by a fraction of which the numerator
      shall be the number of shares of Common Stock of the Company outstanding
      at the close of business on the Dividend Record Date and the denominator
      shall be the sum of such number of shares and the total number of shares
      constituting such dividend or other distribution. Such reduction shall
      become effective immediately after the opening of business on the day
      following the date fixed for such determination. For the purposes of this
      paragraph (1), the number of shares of Common Stock of the Company at any
      time outstanding shall not include shares held in the treasury of the
      Company, but shall include shares issuable in respect of scrip
      certificates issued in lieu of fractions of shares of Common Stock. The
      Company shall not pay any dividend or make any distribution on shares of
      Common Stock held in the treasury of the Company.

                  (2) Subject to paragraph (6) of this Section, if the Company
      pays or makes a dividend or other distribution on its Common Stock
      consisting exclusively of Short Term Rights (as defined below), or
      otherwise issues Short Term Rights to all holders of its Common Stock, the
      Conversion Price in effect at the opening of business on the day following
      the record date for the determination of holders of Common Stock entitled
      to receive such Short Term Rights (the "Rights Record Date") shall be
      reduced by multiplying such Conversion Price by a fraction of which the
      numerator shall be the number of shares of Common Stock of the Company
      outstanding at the close of business on the Rights Record Date plus the
      number of shares of Common Stock of the

                                       91


<PAGE>   99


      Company which the aggregate of the offering price of the total number of
      shares of Common Stock so offered for subscription or purchase would
      purchase at such current market price and the denominator shall be the
      number of shares of Common Stock of the Company outstanding at the close
      of business on the Rights Record Date plus the number of shares of Common
      Stock so offered for subscription or purchase. Such reduction shall become
      effective immediately after the opening of business on the day following
      the Rights Record Date. For the purposes of this paragraph (2), the number
      of shares of Common Stock of the Company at any time outstanding shall not
      include shares held in the treasury of the Company, but shall include
      shares issuable in respect of scrip certificates issued in lieu of
      fractions of shares of Common Stock of the Company. The Company shall not
      issue any rights, options or warrants in respect of shares of its Common
      Stock held in the treasury of the Company. When used in this Section 1704,
      the term "Short Term Rights" shall mean rights, warrants or options
      entitling the holders thereof (for a period commencing no earlier than the
      Rights Record Date and expiring not more than 45 days after the Rights
      Record Date) to subscribe for or purchase shares of Common Stock of the
      Company at a price per share less than the current market price per share
      (determined as provided in paragraph (7) of this Section 1704) of the
      Common Stock of the Company on the Rights Record Date.

                  (3) In case outstanding shares of Common Stock of the Company
      shall be subdivided into a greater number of shares of Common Stock, the
      Conversion Price in effect at the opening of business on the day following
      the day upon which such subdivision becomes effective shall be
      proportionately reduced, and, conversely, in case outstanding shares of
      Common Stock of the Company shall be combined into a smaller number of
      shares of Common Stock, the Conversion Price in effect at the opening of
      business on the day following the day upon which such combination becomes
      effective shall be proportionately increased, such reduction or increase,
      as the case may be, to become effective immediately after the opening of
      business on the day following the day upon which such subdivision or
      combination becomes effective.

                  (4) Subject to the last sentence of this paragraph (4) of this
      Section, if the Company, by dividend or otherwise, (a) distributes to all
      holders of its Common Stock evidences of its indebtedness, shares of any
      class of Capital Stock of the Company or other assets (other than cash
      dividends out of current or retained earnings), or (b) distributes to
      substantially all holders of Common Stock rights or warrants to subscribe
      for securities (other than Short Term Rights to which paragraph (2) of
      this Section 1704 applies), the Conversion Price shall be reduced by
      multiplying such Conversion Price by a fraction of which the numerator
      shall be the current market price per share (determined as provided in
      paragraph (7) of this Section 1704) of the Common Stock of the Company on
      the Reference Date (as defined below) less the fair market value (as
      determined in good faith by the Board of Directors, whose determination
      shall be conclusive and described in a Board Resolution filed with the
      Trustee), on the Reference Date, of the portion of the evidences of
      indebtedness and other assets so distributed or of such subscription
      rights or warrants

                                       92


<PAGE>   100


      applicable to one share of Common Stock (collectively, the "Market Value
      of the Distribution") and the denominator shall be such current market
      price per share of the Common Stock of the Company. Such reduction shall
      become effective immediately prior to the opening of business on the day
      (the "Reference Date") following the later of (a) the date fixed for the
      payment of such distribution and (b) the date 20 days after notice
      relating to such distribution is required to be given pursuant to Section
      1706(a). If the Board of Directors determines the fair market value of any
      distribution for purposes of this paragraph (4) by reference to the actual
      or when issued trading market for any securities comprising such
      distribution, it must in doing so consider the prices in such market over
      the same period used in computing the current market price per share
      pursuant to paragraph (7) of this Section 1704. In the event that, with
      respect to any distribution to which this paragraph (4) of Section 1704
      would otherwise apply, the Market Value of the Distribution is greater
      than the current market price per share of the Common Stock (such
      distribution being referred to herein as an "Unadjusted Distribution"),
      then the adjustment provided by this paragraph (4) shall not be made and
      in lieu thereof the provisions of Section 1711 shall apply with respect to
      such Unadjusted Distribution.

                  (5) The Company may, but shall not be required to, make such
      reductions in the Conversion Price, in addition to those required by
      paragraphs (1), (2), (3), and (4) of this Section 1704, as it considers to
      be advisable in order that any event treated for Federal income tax
      purposes as a dividend of stock or stock rights shall not be taxable to
      the recipients. In addition, the Company, from time to time, may decrease
      the Conversion Price by any amount and for any reason, temporarily or
      otherwise, including situations where the Board of Directors determines
      such decrease to be fair and appropriate with respect to transactions in
      which holders of Common Stock have the right to participate.

                  (6) Rights or warrants issued or distributed by the Company to
      all holders of its Common Stock entitling the holders thereof to subscribe
      for or purchase shares of Common Stock or Preferred Stock, which rights or
      warrants (i) are deemed to be transferred with such shares of Common
      Stock, (ii) are not exercisable and (iii) are also issued or distributed
      in respect of future issuances of Common Stock, in each case in clauses
      (i) through (iii) until the occurrence of a specified event or events
      ("Trigger Events"), shall for purposes of this Section 1704 not be deemed
      issued or distributed until the occurrence of the earliest Trigger Event.
      Each share of Common Stock issued upon conversion of Securities pursuant
      to this Article Seventeen shall be entitled to receive the appropriate
      number of Common Stock purchase rights (the "Rights"), if any, and the
      certificates representing the Common Stock issued upon conversion shall
      bear such legends, if any[, in each case as provided by and subject to the
      terms of the [Stockholders Rights Plan] adopted by the Board of Directors
      on ______________ (the "Rights Plan") as in effect at the time of such
      conversion]. Notwithstanding anything to the contrary in this Article
      Seventeen, there shall not be any adjustment to the Conversion Price as a
      result of (i) the distribution of separate

                                       93


<PAGE>   101


      certificates representing the Rights; (ii) the occurrence of certain
      events entitling holders of Rights to receive, upon exercise thereof,
      Common Stock or other securities of the Company or other securities of
      another corporation; or (iii) the exercise of such Rights, all in
      accordance with the Rights Plan. No adjustment in the Conversion Price
      need be made for rights to purchase or the sale of Common Stock pursuant
      to a Company plan providing for reinvestment of dividends or interest.

                  (7) For the purpose of any computation under paragraph (2),
      (4) or (5) of this Section 1704, the "current market price" per share of
      Common Stock of the Company on any date shall be deemed to be the average
      of the daily Closing Prices for the 15 consecutive Trading Days selected
      by the Company commencing not more than 30 Trading Days before, and ending
      not later than, the date in question.

                  (8) No adjustment in the Conversion Price shall be required
      unless such adjustment would require an increase or decrease of at least
      1% in the Conversion Price; PROVIDED, HOWEVER, that any adjustments which
      by reason of this paragraph (8) are not required to be made shall be
      carried forward and taken into account in any subsequent adjustment. All
      calculations under this Article Seventeen shall be made to the nearest
      cent or to the nearest one-hundredth of a share of Common Stock, as the
      case may be.

                  (9) Anything herein to the contrary notwithstanding, in the
      event the Company shall declare any dividend or distribution requiring an
      adjustment in the Conversion Price hereunder and shall, thereafter and
      before the payment of such dividend or distribution to stockholders,
      legally abandon its plan to pay such dividend or distribution, the
      Conversion Price then in effect hereunder, if changed to reflect such
      dividend or distribution, shall upon the legal abandonment of such plan be
      changed to the Conversion Price which would have been in effect at the
      time of such abandonment (after giving effect to all other adjustments not
      so legally abandoned pursuant to the provisions of this Article Seventeen)
      had such dividend or distribution never been declared.

                  (10) Notwithstanding any other provision of this Section 1704,
      no adjustment to the Conversion Price shall reduce the Conversion Price
      below the then par value per share of the Common Stock of the Company, and
      any such purported adjustment shall instead reduce the Conversion Price to
      such par value. Notwithstanding the foregoing sentence, the Company hereby
      covenants that it will from time to time take all such action as may be
      required to assure that the par value per share of the Common Stock is at
      all times equal to or less than the Conversion Price.

                  (11) In the event that this Article Seventeen requires
      adjustments to the Conversion Price under more than one of paragraphs (1),
      (2), (3) or (4) of this Section 1704, and the record or effective dates
      for the transaction giving rise to such

                                       94


<PAGE>   102


      adjustments shall occur on the same date, then such adjustments shall be
      made by applying (to the extent they are applicable), first, the
      provisions of paragraph (3) of this Section 1704, second, the provisions
      of paragraph (1) of this Section 1704, third, the provisions of paragraph
      (4) of this Section 1704 and, fourth, the provisions of paragraph (2) of
      this Section 1704. Anything herein to the contrary notwithstanding, no
      single event shall require or result in duplicative adjustments in the
      Conversion Price pursuant to this Section 1704. After an adjustment to the
      Conversion Price under this Article Seventeen, any subsequent event
      requiring an adjustment under this Article Seventeen shall cause an
      adjustment to the Conversion Price as so adjusted. If, after an
      adjustment, a Holder of a Security upon conversion of such Security
      receives shares of two or more classes of Capital Stock of the Company,
      the Conversion Price shall thereafter be subject to adjustment upon the
      occurrence of an action taken with respect to any such class of Capital
      Stock as is contemplated by this Article Seventeen with respect to the
      Common Stock in this Article Seventeen.

      SECTION 1705.  NOTICE OF ADJUSTMENTS OF CONVERSION PRICE.

      SECTION 1707.  COMPANY TO RESERVE COMMON STOCK.

      The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the

convertible into Common Stock.

      SECTION 1708.  TAXES ON CONVERSION.

      The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

      SECTION 1709.  COVENANTS AS TO COMMON STOCK.

      The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be duly and validly issued, fully
paid and nonassessable, free of preemptive or any similar rights, and, except as
provided in Section 1708, the Company will pay all taxes, liens and charges with
respect to the issue thereof.

      The Company will endeavor promptly to comply with all Federal and state
securities laws regulating the offer and delivery of shares of Common Stock upon
conversion of

                                       96


<PAGE>   104


Securities, if any, and will list or cause to have quoted such shares of Common
Stock on each national securities exchange or in the over-the-counter market or
such other market on which the Common Stock is then listed or quoted.

      SECTION 1710.  CANCELLATION OF CONVERTED SECURITIES.

      All Securities delivered for conversion shall be delivered to the Trustee
to be cancelled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 309.

      SECTION 1711.     PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF 
                        ASSETS; SPECIAL DISTRIBUTIONS.

      If any of the following shall occur, namely: (i) any reclassification or
change of outstanding shares of Common Stock issuable upon conversion of
Securities (other than a change in par value, or from par value to no par value,
or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation or merger to which the Company is a party
other than a merger in which the Company is the continuing corporation and which
does not result in any reclassification of, or change (other than a change in
name, or par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination) in, outstanding shares
of Common Stock or (iii) any sale or conveyance of all or substantially all of
the property or business of the Company as an entirety, then the Person formed
by such consolidation or resulting from such merger or which acquires such
properties or assets, as the case may be, shall as a condition precedent to such
transaction execute and deliver to the Trustee a supplemental indenture
providing that the Holder of each Security then outstanding shall have the right
thereafter, during the period such Security shall be convertible as specified in
Section 1701, to convert such Security only into the kind and amount of
securities, cash and other property receivable, if any, upon such consolidation,
merger, sale, transfer or lease by a holder of the number of shares of Common
Stock of the Company into which such Security might have been converted
immediately prior to such consolidation, merger, sale, transfer or lease;
PROVIDED that the kind and amount of securities, cash and other property so
receivable shall be determined on the basis of the following assumptions. The
holder of Common Stock referred to in the foregoing sentence:

      (1)   is not (a) a Person with which the Company consolidated, (b) a
            Person into which the Company merged or which merged into the
            Company, or (c) a Person to which such sale, transfer or lease was
            made (any Person described in the foregoing clauses (a), (b), or
            (c), hereinafter referred to as a "Constituent Person"), or (d) an
            Affiliate of a Constituent Person; and

      (2)   failed to exercise his rights of election, if any, as to the kind or
            amount of securities, cash and other property receivable upon such
            consolidation, merger, sale, transfer or lease (PROVIDED that if the
            kind or

                                       97


<PAGE>   105


            amount of securities, cash and other property receivable upon such
            consolidation, merger, sale transfer or lease is not the same for
            each share of Common Stock of the Company in respect of which such
            rights of election shall not have been exercised, then for the
            purpose of this Section 1711 the kind and amount of securities, cash
            and other property receivable upon such consolidation, merger, sale,
            transfer or lease shall be deemed to be the kind and amount so
            receivable per share by a plurality of such shares of Common Stock).

      Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article Seventeen. If, in the case of any such consolidation, merger, sale
transfer or lease the stock or other securities and property (including cash)
receivable thereupon by a holder of Common Stock includes shares of stock or
other securities and property of a corporation other than the successor or
purchasing corporation, as the case may be, in such consolidation, merger, sale,
transfer or lease then such supplemental indenture shall also be executed by
such other corporation and shall contain such additional provisions to protect
the interests of the Holders of the Securities as the Board of Directors of the
Company shall reasonably consider necessary by reason of the foregoing. The
above provisions of this Section 1711 shall similarly apply to successive
consolidations, mergers, sales, transfers or leases.

      In the event the Company shall execute a supplemental indenture pursuant
to this Section 1711, the Company shall promptly file with the Trustee an
Officers' Certificate briefly stating the reasons therefor, the kind or amount
of shares of stock or securities or property (including cash) receivable by
Holders of the Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale, transfer or lease and any
adjustment to be made with respect thereto.

      If the Company makes a distribution to all holders of its Common Stock
that constitutes an Unadjusted Distribution pursuant to the last sentence of
paragraph (4) of Section 1704, then, from and after the record date for
determining the holders of Common Stock entitled to receive such distribution
(the "Distribution Record Date"), a Holder of a Security who converts such
Security in accordance with the provisions of this Indenture shall, upon
conversion, be entitled to receive, in addition to the shares of Common Stock
into which the Security is convertible, the kind and amount of evidences of
indebtedness, shares of Capital Stock, or other assets or subscription rights or
warrants, as the case may be, comprising the distribution that such Holder would
have received if such Holder had converted the Security immediately prior to the
Distribution Record Date.

      SECTION 1712.  TRUSTEE ADJUSTMENT DISCLAIMER; COMPANY DETERMINATION FINAL.

      The Trustee has no duty to determine when an adjustment under this Article
Seventeen should be made, how it should be made or what it should be. The
Trustee has no duty to

                                       98


<PAGE>   106


determine whether a supplemental indenture under Section 1711 need be entered
into or whether any provisions of any supplemental indenture are correct. The
Trustee shall not be accountable for and makes no representation as to the
validity or value of any securities or assets issued upon conversion of
Securities. The Trustee shall not be responsible for the Company's failure to
comply with this Article Seventeen. Any determination that the Company or the
Board of Directors must make pursuant to this Article Seventeen is conclusive,
absent manifest error.

      SECTION 1713.  WHEN NO ADJUSTMENT REQUIRED.

            (a) Except as expressly set forth in Section 1704, no adjustment in
the Conversion Price shall be made because the Company issues, in exchange for
cash, property or services, shares of its Common Stock, or any securities
convertible into or exchangeable for shares of its Common Stock, or securities
(including warrants, rights and options) carrying the right to subscribe for or
purchase shares of its Common Stock or such convertible or exchangeable
securities.

            (b) Notwithstanding anything herein to the contrary, no adjustment
in the Conversion Price shall be made pursuant to Section 1704 in respect of any
dividend or distribution if the Holders may participate therein (on a basis to
be determined in good faith by the Board of Directors) and receive the same
consideration they would have received if they had converted the Securities
immediately prior to the record date with respect to such dividend or
distribution.

      SECTION 1714.  EQUIVALENT ADJUSTMENTS.

      In the event that, as a result of an adjustment made pursuant to Section
1704 above, the holder of any Security thereafter surrendered for conversion
shall become entitled to receive any shares of Capital Stock of the Company
other than shares of its Common Stock, thereafter the Conversion Price of such
other shares so receivable upon conversion of any Securities shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to Common Stock contained in this
Article Seventeen.

Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not

also contains provisions permitting the Holders of not less than a majority of

Holders of all such Securities, to waive compliance by the Company with certain
provisions of the Indenture. Furthermore, provisions in the Indenture permit the
Holders of not less than a majority of the aggregate principal amount, in
certain instances, of the Outstanding Securities of any series to waive, on
behalf of all of the Holders of Securities of such series, certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the

where the principal of (and premium or Make-Whole Amount, if any) and interest
on this Security are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or by his attorney duly authorized
in writing, and thereupon one or more new Securities, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

     As provided in the Indenture and subject to certain limitations therein
[and herein] set forth, this Security is exchangeable for a like aggregate
principal amount of Securities of different authorized denominations but
otherwise having the same terms and conditions, as requested by the Holder
hereof surrendering the same.

     This Security is subordinated to the prior payment in full in cash of
Senior Indebtedness to the extent set forth in Article Sixteen of the Indenture.

     The Securities of this series are issuable only in registered form [without
coupons] in denominations of $_______ and any integral multiple thereof.

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

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     No recourse shall be had for the payment of the principal of or premium or
Make-Whole Amount, if any, or the interest on this Security, or for any claim
based hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any past, present or
future stockholder, employee, officer or director, as such, of the Company or of
any successor, either directly or through the Company or any successor, whether
by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

     The Indenture and the Securities shall be governed by and construed in
accordance with the laws of [the State of New York] applicable to agreements
made and to be performed entirely in such State.

Ladies and Gentlemen:
 
     Re:  Legality of Securities to be Registered under
          Registration Statement on Form S-3
 
     This opinion is delivered in our capacity as counsel to TriNet Corporate
Realty Trust, Inc. (the "Company") in connection with the Company's registration
statement on Form S-3 (the "Registration Statement") filed with the Securities
and Exchange Commission under the Securities Act of 1933, as amended, relating
to an indeterminate amount of Debt Securities and shares of Preferred Stock and
Common Stock authorized for issuance under the Company's Articles of
Incorporation, with an aggregate public offering price of up to $400,000,000
(such securities being referred to collectively as the "Securities"). The
Registration Statement provides that the Securities may be offered separately or
together, in separate series, in amounts, at prices and on terms to be set forth
in one or more prospectus supplements (each a "Prospectus Supplement") to the
Prospectus contained in the Registration Statement.
 
     We have examined the Articles of Incorporation of the Company, as amended
and restated to the date hereof and on file with the Maryland State Department
of Assessments and Taxation; the Bylaws of the Company; such records of
corporate proceedings of the Company as we deem appropriate for the purposes of
this opinion; the Registration Statement and the exhibits thereto.
 
     Based upon the foregoing, we are of the opinion that, when specifically
authorized for issuance by the Company's Board of Directors or an authorized
committee thereof (the "Authorizing Resolution") and when issued as described in
the Registration Statement and a Prospectus Supplement that is consistent with
the Authorizing Resolution, and upon receipt by the Company of the consideration
provided for in the Authorizing Resolution (which consideration is not less than
the $.01 par value per share in the case of Common Stock or Preferred Stock),
the Securities will be legally issued, fully paid and nonassessable, and in the
case of Debt Securities, binding obligations of the Company.
 
     We hereby consent to being named as counsel to the Company in the
Registration Statement, to the references therein to our firm under the caption
"Legal Matters" and to the inclusion of this opinion as an exhibit to the
Registration Statement.
 
                                            Very truly yours,

                                As of December 31, 1996

TriNet Corporate Realty Trust, Inc.
Four Embarcadero Center, Suite 3150
San Francisco, CA 94111

Ladies and Gentlemen:

     This opinion is delivered to you in our capacity as counsel to TriNet
Corporate Realty Trust, Inc. (the "Company") in connection with the Company's
registration statement on Form S-3 (the "Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
relating to an indeterminate amount of Debt Securities and shares of Preferred
Stock and Common Stock authorized for issuance under the Company's Articles of
Incorporation, with an aggregate public offering price of up to $400,000,000
(the "Registration Statement"). This opinion relates to the Company's
qualification for federal income tax purposes as a real estate investment trust
("REIT") under the Internal Revenue Code of 1986, as amended (the "Code").

     In rendering the following opinion, we have reviewed and relied upon
copies of the Company's federal income tax returns on Form 1120-REIT, dated
July 6, 1995 for its taxable year ended December, 1994 and dated September 9,
1996 for its taxable year ended December, 1995. We assume that the foregoing
return was timely filed following timely filing of application for automatic
extension of time to file such return, and we assume that a federal income tax
return for the Company's taxable year ended December, 1995 was properly and
timely filed on Form 1120-REIT. We have examined the Articles of Incorporation
and Bylaws of the Company, each as amended, and such other records,
certificates and documents as we have deemed necessary or appropriate for
purposes of rendering the opinions set forth herein.


<PAGE>   2



TriNet Corporate Realty Trust, Inc.
Page 2

     We have reviewed and relied upon the Registration Statement and the
descriptions set forth therein, or incorporated by reference, of the Company and
its investments and activities. We have relied upon the representations of an
officer of the Company dated December 31, 1996 (the "Certificate"), regarding
the manner in which the Company has been and will continue to be owned and
operated. We have not made an independent investigation of any of the facts set
forth in any of the above-referenced documents including the Certificate. Except
as regards the federal income tax requirements relating to the taxation of the
Company as a REIT, which is the subject of this opinion and with regard to which
officers of the Company have certified to the factual matters relating to the
Company's compliance, we assume that the Company has been and will be operated
in accordance with applicable laws and the terms and conditions of applicable
documents, and that the descriptions of the Company and its investments, and the
proposed investments, activities, operations and governance of the Company set
forth in the Registration Statement are true.

     In rendering the opinions set forth herein, we have assumed (i) the
genuineness of all signatures on documents we have examined, (ii) the
authenticity of all documents submitted to us as originals, (iii) the conformity
to the original documents of all documents submitted to us as copies, (iv) the
conformity of final documents to all documents submitted to us as drafts, (v)
the authority and capacity of the individual or individuals who executed any
such documents on behalf of any person, (vi) the accuracy and completeness of
all records made available to us, and (vii) the factual accuracy of all
representations, warranties and other statements made by all parties. We have
also assumed, without investigation, that all documents, certificates,
warranties and covenants on which we have relied in rendering the opinion set
forth below including the representations contained in the Certificate, but
excluding representations made to us in prior certificates which may no longer
accurately reflect the Company's assets or operations solely on account of the
Company's having subsequently (i) acquired properties not referred to therein or
(ii) disposed of properties specifically referred to therein, as the case may
be, and that were given or dated earlier than the date of this letter continue
to remain accurate, insofar as relevant to the opinion set forth herein, from
such earlier date through and including the date of this letter.

     The conclusions set forth below are based upon the Code, the Income Tax
Regulations and Procedure and Administration Regulations promulgated thereunder
and existing administrative and judicial interpretations thereof, all of which
are subject to change. No assurance can therefore be given that the federal
income tax consequences described below will not be altered in the future.

TriNet Corporate Realty Trust, Inc.

     Based upon and subject to the foregoing, we are of the opinion that

     1.   Commencing with the Company's taxable year ended December 31, 1993,
          the Company has been organized in conformity with the requirements for
          qualification as a "real estate investment trust", and its method of
          operation, as described in the Registration Statement and set forth in
          the Certificate, has enabled the Company to meet and, provided that
          the Company continues to meet the applicable asset composition, source
          of income, shareholder diversification, distribution, recordkeeping
          and other requirements of the Code necessary for a corporation to
          qualify as a REIT, will enable it to continue to meet the requirements
          for qualification and taxation as a "real estate investment trust"
          under the Code.

     2.   The Statements in the Registration Statement set forth under the
          caption "Federal Income Tax Considerations" to the extent such
          information constitutes matters of law, summaries of legal matters, or
          legal conclusions, have been reviewed by us and are accurate in all
          material respects.

     We express no opinion with respect to the transactions described in the
Registration Statement other than those expressly set forth herein. Moreover, as
indicated above, the Company's qualification and taxation as a REIT depends upon
the Company's ability to meet, through actual annual operating results,
distribution levels, diversity of stock ownership and the various qualification
tests imposed under the Code, the results of which will not be reviewed by us.
Accordingly, no assurance can be given that the actual results of the Company's
operations for any one taxable year will satisfy such requirements. You should
recognize that our opinion is not binding on the IRS and that the IRS may
disagree with the opinion contained herein. Although we believe that our opinion
will be sustained if challenged, there can be no assurance that this will be the
case. Except as specifically


<PAGE>   4



TriNet Corporate Realty Trust, Inc.

discussed above, the opinion expressed herein is based upon the law as it
currently exists. Consequently, future changes in the law may cause the federal
