for the Company and its consolidated subsidiaries for the periods indicated. 
The ratio of earnings to fixed charges represents the number of times that

                         DESCRIPTION OF DEBT SECURITIES

   
        The Senior Debt Securities are to be issued under an Indenture (the
"Senior Indenture"), between the Company, as issuer, and State Street Bank and
Trust Company of California, N.A., as Trustee (the "Trustee").  The Subordinated
Debt Securities are to be issued under a separate Indenture (the "Subordinated
Indenture"), also between the Company, as issuer, and State Street Bank and
Trust Company of California, N.A., as Trustee.  The Senior Indenture and
Subordinated Indenture are sometimes referred to collectively as the
"Indentures".  A copy of the form of each Indenture is filed as an exhibit to
the Registration Statement of which this Prospectus is a part. The Debt
Securities may be issued from time to time in one or more series.  The
particular terms of each series, or of Debt Securities forming a part of a
series, which are offered by a Prospectus Supplement will be described in such
Prospectus Supplement.
    

         The following summaries of certain provisions of the Indentures do not
purport to be complete and are subject, and are qualified in their entirety by
reference, to all the provisions of the Indentures, including the definitions
therein of certain terms, and, with respect to any particular Debt Securities,
to the description of the terms thereof included in the Prospectus Supplement
relating thereto.  Wherever particular Sections or defined terms of the
Indentures are referred to herein or in a Prospectus Supplement, such Sections
or defined terms are incorporated by reference herein or therein, as the case
may be.

GENERAL

         The Indentures will provide that Debt Securities in separate series
may be issued thereunder from time to time without limitation as to aggregate
principal amount.  The Company may specify a maximum aggregate principal amount
for the Debt Securities of any series. (Section 301) The Debt Securities are to
have such terms and provisions which are not inconsistent with the Indentures,
including as to maturity, principal and interest, as the Company may determine.
Unless otherwise specified in the applicable Prospectus Supplement, the Senior
Debt Securities when issued will be unsecured and unsubordinated obligations of
the Company and will rank on a parity with all other unsecured and
unsubordinated indebtedness of the Company.  The Subordinated Debt Securities
when issued will be subordinated in right of payment to the prior payment in
full of all Senior Debt of the Company, including any outstanding Senior Debt
Securities, as described under "Subordination of Subordinated Debt Securities"
and in the applicable Prospectus Supplement.

         The applicable Prospectus Supplement will set forth whether the Debt
Securities offered shall be Senior Debt Securities or Subordinated Debt
Securities, the price or prices at which the Debt Securities to be offered will
be issued and will describe the following terms of such Debt Securities: (1)
the title of such Debt Securities; (2) any limit on the aggregate principal
amount of such Debt Securities or the series of which they are a part; (3) the
Person to whom any interest on a Debt Security of the series shall be payable,
if other than the Person in whose name that Debt Security (or one or more
predecessor Debt Securities) is registered at the close of business on the
Regular Record Date for such interest; (4) the date or dates on which the
principal of any of such Debt Securities will be payable; (5) the rate or rates
at which any of such Debt Securities will bear interest, if any, the date or
dates from which any such interest will accrue, the Interest Payment Dates on
which any such interest will be payable and the Regular Record Date for any
such interest payable on any Interest Payment Date; (6) the place or places
where the principal of and any premium and interest on any of such Debt
Securities will be payable; (7) the period or periods within which, the price
or prices at which and the terms and conditions on which any




                                      4
<PAGE>   6
   
of such Debt Securities may be redeemed, in whole or in part, at the option of
the Company; (8) the obligation, if any, of the Company to redeem or purchase
any of such Debt Securities pursuant to any sinking fund or analogous provision
or at the option of the Holder thereof, and the period or periods within which,
the price or prices at which and the terms and conditions on which any of such
Debt Securities will be redeemed or purchased, in whole or in part, pursuant to
any such obligation; (9) the denominations in which any of such Debt Securities
will be issuable, if other than denominations of $1,000 and any integral

United States of America is to be determined for any purpose, including for the
purpose of determining the principal amount deemed to be Outstanding at any
time); (12) if the principal of or any premium or interest on any of such Debt
Securities is to be payable, at the election of the Company or the Holder
thereof, in one or more currencies or currency units other than those in which

upon which such election is to be made and the amount so payable (or the manner
in which such amount is to be determined); (13) if other than the entire
principal amount thereof, the portion of the principal amount of any of such
Debt Securities which will be payable upon declaration of acceleration of the
Maturity thereof; (14) if the principal amount payable at the Stated Maturity
of any of such Debt Securities will not be determinable as of any one or more
dates prior to the Stated Maturity, the amount which will be deemed to be such
principal amount as of any such date for any purpose, including the principal
amount thereof which will be due and payable upon any Maturity other than the
Stated Maturity or which will be deemed to be Outstanding as of any such date
(or, in any such case, the manner in which such deemed principal amount is to
be determined); (15) if applicable, that such Debt Securities, in whole or any
specified part, are defeasible pursuant to the provisions of the Indentures
described under "Defeasance and Covenant Defeasance-Defeasance and Discharge"
or "Defeasance and Covenant Defeasance-Defeasance of Certain Covenants," or

         Debt Securities, including Original Issue Discount Securities, may be
sold at a substantial discount below their principal amount.  Certain special
United States federal income tax considerations (if any) applicable to Debt
Securities sold at an original issue discount will be described in the
applicable Prospectus Supplement under "United States Taxation".  In addition,
certain special United States federal income tax or other considerations (if
any) applicable to any Debt Securities which are denominated in a currency or
currency unit other than United States dollars will be described in the
applicable Prospectus Supplement.

CONVERSION RIGHTS

         The terms on which Debt Securities of any series are convertible into
Common Stock or other securities or property will be set forth in the
Prospectus Supplement relating thereto.  Such terms shall include provisions as
to whether conversion is mandatory or at the option of the Holder and may
include provisions pursuant to which the number of shares of Common Stock or
other securities or property to be received by the Holders of Debt Securities
upon conversion would be calculated according to the market price of Common
Stock or other securities or property as of a time stated in the applicable
Prospectus Supplement. (Article Fourteen)

SUBORDINATION OF SUBORDINATED DEBT SECURITIES

         Unless otherwise indicated in the Prospectus Supplement, the following
provisions will apply to the Subordinated Debt Securities.

   
         The Subordinated Debt Securities will, to the extent set forth in the
Subordinated Indenture, be subordinate in right of payment to the prior payment
in full of all Senior Debt, including the Senior Debt Securities.  In the event
of any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization, debt restructuring or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or any liquidation, dissolution or other winding up
of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or any assignment for the benefit of creditors or any
other marshaling of assets and liabilities of the Company, the holders of Senior
Debt will be entitled to receive payment in full of all amounts due or to become
due on or in respect of all Senior Debt, or provision will be made for such
payment, in money or money's worth, before the Holders of the Subordinated Debt
Securities are entitled to receive any payment on account of principal of or any
premium or interest on the Subordinated Debt Securities or on account of the
purchase, redemption or other acquisition of Subordinated Debt Securities.
(Section 1502)
    
   
         By reason of such subordination, in the event of liquidation or
insolvency, creditors of the Company who are not holders of Senior Debt may
recover less, ratably, than holders of Senior Debt and may recover more, 
ratably, than the Holders of the Subordinated Debt Securities.
    
   
         In the event that any Subordinated Debt Securities are declared due
and payable before their Stated Maturity as a result of an Event of Default,
the holders of the Senior Debt outstanding at the time such Subordinated Debt
Securities so become due and payable will be entitled to receive payment in
full of all amounts due or to become due on or in respect of all Senior Debt,
or provision shall be made for such payment, in money or money's worth, before
the Holders of the Subordinated Debt Securities are entitled to receive any
payment by the Company on account of the principal of or any premium or
interest on the Subordinated Debt Securities or on account of the purchase,
redemption or other acquisition of Subordinated Debt Securities.  If the
payment of Subordinated Debt Securities is accelerated because of an Event of
Default, the Company is required under the Subordinated Indenture to promptly
notify holders of Senior Debt of the acceleration.  (Section 1503)
    

   
         The Company may not make any payment of principal (or premium, if any)
or interest, if any, in respect of the Subordinated Debt Securities or on
account of the purchase, redemption or other acquisition of Subordinated Debt
Securities if (i) a default in the payment of principal, premium, if any,
    



                                      6
<PAGE>   8
   
or interest (including a default under any repurchase or redemption obligation)
or other amounts with respect to any Senior Debt occurs and is continuing beyond
the applicable grace period or (ii) any other event of default occurs and is
continuing with respect to Designated Senior Debt (as defined) that permits the
holders thereof or their representatives to accelerate the maturity thereof, and
the Trustee under the Subordinated Indenture receives a notice of such default
(a "Payment Blockage Notice") from the Company, a holder of such Designated
Senior Debt or other person permitted to give such notice under the Subordinated
Indenture.  The Company may and shall resume payments on the Subordinated Debt
Securities and may purchase, redeem or otherwise acquire the Subordinated Debt
Securities (a) in the case of a payment default, upon the date on which such
default is cured or waived and (b) in the case of a nonpayment default, 179
days after the date on which the applicable Payment Blockage Notice is received
(unless the subordination provisions of Article Fifteen of the Indenture
prohibit the payment or distribution at the time of such payment or distribution
(including, without limitation, in the case of a nonpayment default referred to
in clause (ii) above, as a result of a payment default with respect to the
applicable Senior Debt as a consequence of the acceleration of the maturity
thereof or otherwise)).  No new period of payment blockage may be commenced
unless and until (i) 365 days have elapsed since the effectiveness of the
immediately prior Payment Blockage Notice and (ii) all scheduled payments of
principal, premium, if any, and interest on the Subordinated Debt Securities
that have come due have been paid in full in cash.  No nonpayment default that
existed or was continuing on the date of delivery of any Payment Blockage Notice
to the Trustee under the Subordinated Indenture shall be, or be made, the basis
for a subsequent Payment Blockage Notice. (Section 1504)  In the case of
Subordinated Debt Securities that are convertible at the option of the Holder,
the payment, issuance and delivery of cash, property or securities (other than
stock and certain subordinated securities of the Company) upon conversion of a
Subordinated Debt Security will be deemed to constitute payment on account of
the principal of such Subordinated Debt Security.  (Section 1515)
    

   
        "Senior Debt" is defined in the Subordinated Indenture to mean: the
principal of (and premium, if any) and interest, if any (including interest
accruing on or after the filing of any petition in bankruptcy or for
reorganization relating to the Company to the extent that such claim for
post-petition interest is allowed in such proceeding), on, rent with respect to,
and all fees and other amounts payable in connection with, the following,
whether absolute or contingent, secured or unsecured, due or to become due,
outstanding on the date of the Subordinated Indenture or thereafter created,
incurred or assumed:  (a) indebtedness of the Company evidenced by a credit or
loan agreement, note, bond, debenture or other written obligation, (b) all
obligations of the Company for money borrowed, (c) all obligations of the
Company evidenced by a note or similar instrument given in connection with the
acquisition of any businesses, properties or assets of any kind, (d) obligations
of the Company (i) as lessee under leases required to be capitalized on the
balance sheet of the lessee under generally accepted accounting principles, (ii)
as lessee under other leases for facilities, equipment or related assets,
whether or not capitalized, entered into or leased after the date of the
Subordinated Indenture for financing purposes (as determined by the Company) or
(iii) under any lease or related document (including a purchase agreement) that
provides that the Company is contractually obligated to purchase or cause a
third party to purchase the leased property and the obligations of the Company
under such lease or related document to purchase or to cause a third party to
purchase such leased property, (e) all obligations of the Company under interest
rate and currency swaps, caps, floors, collars, hedge agreements, forward
contracts, or similar agreements or arrangements, (f) all obligations of the
Company with respect to letters of credit, bankers' acceptances or similar
facilities (including reimbursement obligations with respect to any of the
foregoing), (g) all obligations of the Company issued or assumed as the deferred
purchase price of property or services (but excluding trade accounts payable
arising in the ordinary course of business), (h) all obligations of the type
referred to in clauses (a) through (g) above of another Person and all dividends
of another Person, the payment of which, in either case, the Company has assumed
or guaranteed (or in effect guaranteed through an agreement to purchase or
otherwise (including, without limitation, "take or pay" and similar
arrangements)), or for which the Company is responsible or liable, directly or
indirectly, jointly or severally, as obligor, guarantor or otherwise, or which
is secured by a lien on property of the Company, and all obligations of the
Company with respect thereto, and (i) renewals, extensions, modifications,
replacements, restatements and refundings of, or any indebtedness or obligation
issued in exchange for, any such indebtedness or obligation described in clauses
(a) through (h) of this paragraph; provided, however, that Senior Debt shall not
include the Subordinated Debt Securities or any such indebtedness or obligation
if the terms of such indebtedness or obligation (or the terms of the instrument
under which, or pursuant
    



                                      7
<PAGE>   9
to which it is issued) expressly provide that such indebtedness or obligation
is not superior in right of payment to the Subordinated Debt Securities.
   
         "Designated Senior Debt" means the Company's obligations under certain
existing Senior Debt (including its existing bank revolving credit agreement and
bank term loan agreement and the 7.15% Senior Notes due September 15, 2000) and
the Company's obligations under any other particular Senior Debt in which the
instrument creating or evidencing the same or the assumption or guarantee
thereof (or related agreements or documents to which the Company is a party)
expressly provides that such Senior Debt shall be "Designated Senior Debt" for
purposes of the Subordinated Indenture (provided that such instrument, agreement
or other document may place limitations and conditions on the right of such
Senior Debt to exercise the rights of Designated Senior Debt).
    
         The Subordinated Indenture does not limit or prohibit the incurrence
of additional Senior Debt, which may include indebtedness that is senior to the
Subordinated Debt Securities, but subordinate to other obligations of the
Company.  The Senior Debt Securities, when issued, will constitute Senior Debt.

         The Prospectus Supplement may further describe the provisions, if any,
applicable to the subordination of the Subordinated Debt Securities of a
particular series.

FORM, EXCHANGE AND TRANSFER

         The Debt Securities of each series will be issuable only in fully
registered form, without coupons, and, unless otherwise specified in the
applicable Prospectus Supplement, only in denominations of $1,000 and integral
multiples thereof. (Section 302)

         At the option of the Holder, subject to the terms of the Indentures
and the limitations applicable to Global Securities, Debt Securities of each
series will be exchangeable for other Debt Securities of the same series of any
authorized denomination and of a like tenor and aggregate principal amount.
(Section 305)

         Subject to the terms of the Indentures and the limitations applicable
to Global Securities, Debt Securities may be presented for exchange as provided
above or for registration of transfer (duly endorsed or with the form of
transfer endorsed thereon duly executed) at the office of the Security
Registrar or at the office of any transfer agent designated by the Company for
such purpose.  No service charge will be made for any registration of transfer
or exchange of Debt Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.  Such transfer or exchange will be effected upon the Security
Registrar or such transfer agent, as the case may be, being satisfied with the
documents of title and identity of the person making the request.  The Company
has appointed the Trustee as Security Registrar.  Any transfer agent (in
addition to the Security Registrar) initially designated by the Company for any
Debt Securities will be named in the applicable Prospectus Supplement. (Section
305) The Company may at any time designate additional transfer agents or
rescind the designation of any transfer agent or approve a change in the office
through which any transfer agent acts, except that the Company will be required
to maintain a transfer agent in each Place of Payment for the Debt Securities
of each series.  (Section 1002)

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



                                      8
<PAGE>   10
that may be selected for redemption and ending at the close of business on the
day of such mailing or (ii) register the transfer of or exchange any Debt
Security so selected for redemption, in whole or in part, except the unredeemed
portion of any such Debt Security being redeemed in part. (Section 305)

GLOBAL SECURITIES

         Some or all of the Debt Securities of any series may be represented,
in whole or in part, by one or more global securities which will have an
aggregate principal amount equal to that of the Debt Securities represented
thereby (a "Global Security").  Each Global Security will be registered in the
name of a depositary (the "Depositary") or a nominee thereof identified in the
applicable Prospectus Supplement, will be deposited with such Depositary or
nominee or a custodian therefor and will bear a legend regarding the
restrictions on exchanges and registration of transfer thereof referred to
below and any such other matters as may be provided for pursuant to the
Indentures.

         Notwithstanding any provision of the Indentures or any Debt Security
described herein, no Global Security may be exchanged in whole or in part for
Debt Securities registered, and no transfer of a Global Security in whole or in
part may be registered, in the name of any Person other than the Depositary for
such Global Security or any nominee of such Depositary unless (i) the
Depositary has notified the Company that it is unwilling or unable to continue
as Depositary for such Global Security or has ceased to be qualified to act as
such as required by the Indentures, (ii) there shall have occurred and be
continuing an Event of Default with respect to the Debt Securities represented
by such Global Security or (iii) there shall exist such circumstances, if any,
in addition to or in lieu of those described above as may be described in the
applicable Prospectus Supplement.  All securities issued in exchange for a
Global Security or any portion thereof will be registered in such names as the
Depositary may direct. (Sections 204 and 305)

         As long as the Depositary, or its nominee, is the registered Holder of
a Global Security, the Depositary or such nominee, as the case may be, will be
considered the sole owner and Holder of such Global Security and the Debt
Securities represented thereby for all purposes under the Debt Securities and
the Indentures.  Except in the limited circumstances referred to above, owners
of beneficial interests in a Global Security will not be entitled to have such
Global Security or any Debt Securities represented thereby registered in their
names, will not receive or be entitled to receive physical delivery of
certificated Debt Securities in exchange therefor and will not be considered to
be the owners or Holders of such Global Security or any Debt Securities
represented thereby for any purpose under the Debt Securities or the
Indentures.  All payments of principal of and any premium and interest on a
Global Security will be made to the Depositary or its nominee, as the case may
be, as the Holder thereof.  The laws of some jurisdictions require that certain
purchasers of securities take physical delivery of such securities in
definitive form.  These laws may impair the ability to transfer beneficial
interests in a Global Security.

         Ownership of beneficial interests in a Global Security will be limited
to institutions that have accounts with the Depositary or its nominee
("participants") and to persons that may hold beneficial interests through
participants.  In connection with the issuance of any Global Security, the
Depositary will credit, on its book-entry registration and transfer system, the
respective principal amounts of Debt Securities represented by the Global
Security to the accounts of its participants.  Ownership of beneficial
interests in a Global Security will be shown only on, and the transfer of those
ownership interests will be effected only through, records maintained by the
Depositary (with respect to participants' interests) or any such participant
(with respect to interests of persons held by such participants on their
behalf).




                                      9
<PAGE>   11
Payments, transfers, exchanges and others matters relating to beneficial
interests in a Global Security may be subject to various policies and
procedures adopted by the Depositary from time to time.  None of the Company,
the Trustee or any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the Depositary's or any
participant's records relating to, or for payments made on account of,
beneficial interests in a Global Security, or for maintaining, supervising or
reviewing any records relating to such beneficial interests.

PAYMENT AND PAYING AGENTS

         Unless otherwise indicated in the applicable Prospectus Supplement,
payment of interest on a Debt Security on any Interest Payment Date will be
made to the Person in whose name such Debt Security (or one or more Predecessor
Debt Securities) is registered at the close of business on the Regular Record
Date for such interest. (Section 307)

   
         Unless otherwise indicated in the applicable Prospectus Supplement,
principal of and any premium and interest on the Debt Securities of a particular
series will be payable at the office of such Paying Agent or Paying Agents as
the Company may designate for such purpose from time to time, except that at the
option of the Company payment of any interest may be made by check mailed to the
address of the Person entitled thereto as such address appears in the Security
Register.  Unless otherwise indicated in the applicable Prospectus Supplement,
the Corporate Trust Office of the Trustee will be designated as the Company's
sole Paying Agent for payments with respect to Debt Securities of each series.
Any other Paying Agents initially designated by the Company for the Debt
Securities of a particular series will be named in the applicable Prospectus
Supplement.  The Company may at any time designate additional Paying Agents or
rescind the designation of any Paying Agent or approve a change in the office
through which any Paying Agent acts, except that the Company will be required to
maintain a Paying Agent in each Place of Payment for the Debt Securities of a
particular series. (Section 1002)
    

         All moneys paid by the Company to a Paying Agent for the payment of
the principal of or any premium or interest on any Debt Security which remain
unclaimed at the end of two years after such principal, premium 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.
(Section 1003)

RESTRICTIVE COVENANTS

         Unless otherwise indicated in the applicable Prospectus Supplement,
the following provisions will apply to the Senior Debt Securities.

Limitations on Liens

         The Senior Indenture will provide that the Company will not issue,
incur, create, assume or guarantee, and will not permit any Restricted
Subsidiary (as defined below) to issue, incur, create, assume or guarantee, any
debt for borrowed money secured by a mortgage, security interest, pledge, lien,
charge or other encumbrance ("mortgages") upon any Principal Property (as
defined below) of the Company or any Restricted Subsidiary or upon any shares
of stock or indebtedness of any Restricted Subsidiary (whether such Principal
Property, shares or indebtedness are now existing or owned or hereafter created
or acquired) without in any such case effectively providing concurrently with
the issuance, incurrence, creation, assumption or guarantee of any such secured
debt, or the grant of a mortgage with respect to




                                      10
<PAGE>   12
any such indebtedness, that the Senior Debt Securities (together with, if the
Company shall so determine, any other indebtedness of or guarantee by the
Company or such Restricted Subsidiary ranking equally with the Senior Debt
Securities) shall be secured equally and ratably with (or, at the option of the
Company, prior to) such secured debt.  The foregoing restriction, however, will
not apply to: (a) mortgages on property existing at the time of acquisition
thereof by the Company or any Subsidiary, provided that such mortgages were in
existence prior to the contemplation of such acquisition; (b) mortgages on
property, shares of stock or indebtedness or other assets of any corporation
existing at the time such corporation becomes a Restricted Subsidiary, provided
that such mortgages are not incurred in anticipation of such corporation
becoming a Restricted Subsidiary; (c) mortgages on property, shares of stock or
indebtedness existing at the time of acquisition thereof by the Company or a
Restricted Subsidiary or mortgages thereon to secure the payment of all or any
part of the purchase price thereof, or mortgages on property, shares of stock
or indebtedness to secure any indebtedness for borrowed money incurred prior
to, at the time of, or within 270 days after, the latest of the acquisition
thereof, or, in the case of property, the completion of construction, the
completion of improvements, or the commencement of substantial commercial
operation of such property for the purpose of financing all or any part of the
purchase price thereof, such construction, or the making of such improvements;
(d) mortgages to secure indebtedness owing to the Company or to a Restricted
Subsidiary; (e) mortgages existing at the date of the Senior Indenture; (f)
mortgages on property of a corporation existing at the time such corporation is
merged into or consolidated with the Company or a Restricted Subsidiary or at
the time of a sale, lease or other disposition of the properties of a
corporation as an entirety or substantially as an entirety to the Company or a
Restricted Subsidiary, provided that such mortgage was not incurred in
anticipation of such merger or consolidation or sale, lease or other
disposition; (g) mortgages in favor of the United States or any State,
territory or possession thereof (or the District of Columbia), or any
department, agency, instrumentality or political subdivision of the United
States or any State, territory or possession thereof (or the District of
Columbia), to secure partial, progress, advance or other payments pursuant to
any contract or statute or to secure any indebtedness incurred for the purpose
of financing all or any part of the purchase price or the cost of constructing
or improving the property subject to such mortgages; (h) mortgages created in
connection with the acquisition of assets or a project financed with, and
created to secure, a Nonrecourse Obligation (as defined below); and (i)
extensions, renewals, refinancings or replacements of any mortgage referred to
in the foregoing clauses (a), (b), (c), (d), (e), (f), (g), and (h) provided,
however, that any mortgages permitted by any of the foregoing clauses (a), (b),
(c), (d), (e), (f), (g), and (h) shall not extend to or cover any property of
the Company or such Restricted Subsidiary, as the case may be, other than the
property, if any, specified in such clauses and improvements thereto, and
provided further that any refinancing or replacement of any mortgages permitted
by the foregoing clauses (g) and (h) shall be of the type referred to in such
clauses (g) or (h), as the case may be.

         Notwithstanding the restrictions described in the preceding paragraph,
the Company or any Restricted Subsidiary will be permitted to issue, incur,
create, assume or guarantee debt secured by a mortgage which would otherwise be
subject to such restrictions, without equally and ratably securing the Senior
Debt Securities, provided that after giving effect thereto, the aggregate
amount of all debt so secured by mortgages (not including mortgages permitted
under clauses (a) through (i) above) does not exceed 15% of the Consolidated
Net Tangible Assets (as defined below) of the Company as most recently
determined on or prior to such date.




                                      11
<PAGE>   13
Limitations on Sale and Lease-Back Transactions

         The Senior Indenture will provide that the Company will not, nor will
it permit any Restricted Subsidiary to, enter into any Sale and Lease-Back
Transaction (as defined below) with respect to any Principal Property, other
than any such transaction involving a lease for a term of not more than three
years or any such transaction between the Company and a Restricted Subsidiary
or between Restricted Subsidiaries, unless (a) the Company or such Restricted
Subsidiary would be entitled to incur indebtedness secured by a mortgage on the
Principal Property involved in such transaction at least equal in amount to the
Attributable Debt (as defined below) with respect to such Sale and Lease-Back
Transaction, without equally and ratably securing the Senior Debt Securities,
pursuant to the limitation on liens in the Senior Indenture; or (b) the Company
shall apply an amount equal to the greater of the net proceeds of such sale or
the Attributable Debt with respect to such Sale and Lease-Back Transaction
within 180 days of such sale to either (or a combination of) the retirement
(other than any mandatory retirement, mandatory prepayment or sinking fund
payment or by payment at maturity) of debt for borrowed money of the Company or
a Restricted Subsidiary that matures more than 12 months after the creation of
such indebtedness or the purchase, construction or development of other
comparable property.

Certain Definitions Applicable to Covenants

   
         The term "Attributable Debt" when used in connection with a Sale and
Lease-Back Transaction involving a Principal Property shall mean, at the time
of determination, the lesser of: (a) the fair value of such property (as
determined in good faith by the Board of Directors of the Company); or (b) the
present value of the total net amount of rent required to be paid under such
lease during the remaining term thereof (including any renewal term or period
for which such lease has been extended), discounted at the rate of interest set
forth or implicit in the terms of such lease or if not practicable to determine
such rate, the weighted average interest rate per annum (in the case of
Original Issue Discount Securities, the imputed interest rate) borne by the
Senior Debt Securities of each series outstanding pursuant to the Indenture
compounded semi-annually.  For purposes of the foregoing definition, rent shall
not include amounts required to be paid by the lessee, whether or not
designated as rent or additional rent, on account of or contingent upon
maintenance and repairs, insurance, taxes, assessments, water rates and similar
charges.  In the case of any lease which is terminable by the lessee upon the
payment of a penalty, such net amount shall be the lesser of the net amount
determined assuming termination upon the first date such lease may be
terminated (in which case the net amount shall also include the amount of the
penalty, but no rent shall be considered as required to be paid under such
lease subsequent to the first date upon which it may be so terminated) and the
net amount determined assuming no such termination.
    

   
         The term "Consolidated Net Tangible Assets" shall mean, as of any
particular time, total assets (excluding applicable reserves and other properly
deductible items) less: (a) total current liabilities, except for (1) notes and
loans payable; (2) current maturities of long-term debt and (3) current
maturities of obligations under capital leases; and (b) goodwill, patents and
trademarks, to the extent included in total assets; all as set forth on the
most recent consolidated balance sheet of the Company and its Restricted
Subsidiaries and computed in accordance with generally accepted accounting
principles.
    

         The term "Nonrecourse Obligation" means indebtedness or other
obligations substantially related to (i) the acquisition of assets not
previously owned by the Company or any Restricted Subsidiary or (ii) the
financing of a project involving the development or expansion of properties of
the Company or

any Restricted Subsidiary, as to which the obligee with respect to such
indebtedness or obligation has no recourse to the Company or any Restricted
Subsidiary or any assets of the Company or any Restricted Subsidiary other than
the assets which were acquired with the proceeds of such transaction or the
project financed with the proceeds of such transaction (and the proceeds
thereof).

         The term "Principal Property" shall mean the land, land improvements,
buildings and fixtures (to the extent they constitute real property interests,
including any leasehold interest therein) constituting the principal corporate
office, any manufacturing facility or any distribution center (whether now
owned or hereafter acquired) which: (a) is owned by the Company or any
Subsidiary; (b) is located within any of the present 50 states of the United
States (or the District of Columbia); (c) has not been determined in good faith
by the Board of Directors of the Company not to be materially important to the
total business conducted by the Company and its Subsidiaries taken as a whole;
and (d) has a market value on the date as of which the determination is being
made in excess of 2.0% of Consolidated Net Tangible Assets of the Company as
most recently determined on or prior to such date.

   
         The term "Restricted Subsidiary" shall mean any Subsidiary that owns
any Principal Property; provided, however, that the term "Restricted
Subsidiary" shall not include (a) any Subsidiary which is principally engaged
in financing receivables, or which is principally engaged in financing the
Company's operations outside the United States of America or (b) any
Subsidiary less than 80% of the voting stock of which is owned, directly or
indirectly, by the Company or by one or more other Subsidiaries, or by the
Company and one or more other Subsidiaries if the common stock of such
Subsidiary is traded on any national securities exchange or quoted on the
Nasdaq National Market or in the over-the-counter market.
    

         The term "Sale and Lease-Back Transaction" shall mean any arrangement
with any person providing for the leasing by the Company or any Restricted
Subsidiary of any Principal Property which property has been or is to be sold
or transferred by the Company or such Restricted Subsidiary to such person.

   
         The term "Subsidiary" shall mean any corporation of which at least a
majority of the outstanding voting stock having the power to elect a majority of
the board of directors of such corporation is at the time owned, directly or
indirectly, by the Company or by one or more other Subsidiaries, or by the
Company and one or more other Subsidiaries, and the accounts of which are
consolidated with those of the Company in the most recent consolidated
financial statements in accordance with generally accepted accounting
principles.  For the purposes of this definition, "voting stock" means stock
which ordinarily has voting power for the election of directors, whether at all
times or only so long as no senior class of stock has such voting power by
reason of any contingency.
    

CONSOLIDATION, MERGER AND SALE OF ASSETS

   
         The Indentures will provide that the Company may not consolidate with
or merge into any other Person (in a transaction in which the Company is not
the surviving corporation), or convey, transfer or lease its properties and
assets substantially as an entirety to, any Person (a "Successor Person"),
unless (i) the Successor Person (if any) is a corporation, limited liability
company, partnership, trust or other entity organized and existing under the
laws of any domestic jurisdiction and assumes the Company's obligations on the
Debt Securities and under the Indentures, (ii) immediately after giving effect
to the transaction, and treating any indebtedness which becomes an obligation
of the Company or any Subsidiary as a result of the transaction as having been
incurred by it at the time of the transaction, no Event of Default, and no
event which, after notice or lapse of time or both, would become an Event of
Default, shall have occurred and be continuing, 
    




                                      13
<PAGE>   15
   
and (iii) certain other conditions are met. (Section 801)
    

EVENTS OF DEFAULT

   
         Each of the following will constitute an Event of Default under the
Indentures with respect to Debt Securities of any series: (a) failure to pay
principal of or any premium on any Debt Security of that series when due,
whether or not such payment is prohibited by the subordination provisions of the
Subordinated Indenture; (b) failure to pay any interest on any Debt Securities
of that series when due, continued for 30 days, whether or not such payment is
prohibited by the subordination provisions of the Subordinated Indenture; (c)
failure to deposit any sinking fund payment, when due, in respect of any Debt
Security of that series, whether or not such deposit is prohibited by the
subordination provisions of the Subordinated Indenture; (d) failure to perform
any other covenant of the Company in the Indentures (other than a covenant
included in the Indentures solely for the benefit of a series other than that
series), continued for 60 days after written notice has been given by the
Trustee, or the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series, as provided in the Indentures; (e)
certain events in bankruptcy, insolvency or reorganization with respect to the
Company; and (f) any other Event of Default specified in the applicable
Prospectus Supplement. (Section 501)
    

   
         The Indentures will provide that, if an Event of Default (other than an
Event of Default described in clause (e) above) with respect to the Debt
Securities of any series at the time Outstanding shall occur and be continuing,
either the Trustee or the Holders of at least 25% in aggregate principal amount
of the Outstanding Securities of that series by notice as provided in the
Indentures may declare the principal amount of the Debt Securities of that
series (or, in the case of any Debt Security that is an Original Issue Discount
Security or the principal amount of which is not then determinable, such
portion of the principal amount of such Debt Security, or such other amount in
lieu of such principal amount, as may be specified in the terms of such Debt
Security) to be due and payable immediately.  If an Event of Default described
in clause (e) above with respect to the Debt Securities of any series at the
time Outstanding shall occur, the principal amount of all the Debt Securities
of that series (or, in the case of any such Original Issue Discount Security or
other Debt Security, such specified amount) will automatically, and without any
action by the Trustee or any Holder, become immediately due and payable.  After
any such acceleration, but before a judgment or decree based on acceleration,
the Holders of a majority in aggregate principal amount of the Outstanding
Securities of that series may, under certain circumstances, rescind and annul
such acceleration if all Events of Default, other than the non-payment of
accelerated principal (or other specified amount), have been cured or waived as
provided in the Indentures. (Section 502) For information as to waiver of
defaults, see "Modification and Waiver".
    

         Subject to the provisions of the Indentures relating to the duties of
the Trustee in case an Event of Default shall occur and be continuing, the
Trustee will be under no obligation to exercise any of its rights or powers
under the Indentures at the request or direction of any of the Holders, unless
such Holders shall have offered to the Trustee reasonable indemnity. (Section
603) Subject to such provisions for the indemnification of the Trustee, the
Holders of a majority in aggregate principal amount of the Outstanding
Securities of any series will 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 Debt
Securities of that series. (Section 512)



                                      14
<PAGE>   16
         No Holder of a Debt Security of any series will have any right to
institute any proceeding with respect to the Indentures, or for the appointment
of a receiver or a trustee, or for any other remedy thereunder, unless (i) such
Holder has previously given to the Trustee written notice of a continuing Event
of Default with respect to the Debt Securities of that series, (ii) the Holders
of at least 25% in aggregate principal amount of the Outstanding Securities of
that series have made a written request, and such Holder or Holders have
offered reasonable indemnity, to the Trustee to institute such proceeding as
trustee and (iii) the Trustee has failed to institute such proceeding, and has
not received from the Holders of a majority in aggregate principal amount of
the Outstanding Securities of that series a direction inconsistent with such
request, within 60 days after such notice, request and offer. (Section 507)
However, such limitations do not apply to a suit instituted by a Holder of a
Debt Security for the enforcement of payment of the principal of or any premium
or interest on such Debt Security on or after the applicable due date specified
in such Debt Security. (Section 508)

         The Indentures will include a covenant requiring the Company to
furnish to the Trustee annually a statement by certain of its officers as to
whether or not the Company, to their knowledge, is in default in the
performance or observance of any of the terms, provisions and conditions of the
Indentures and, if so, specifying all such known defaults. (Section 1004)

MODIFICATION AND WAIVER

         Modifications and amendments of the Indentures may be made by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series
affected by such modification or amendment; provided, however, that no such
modification or amendment may, without the consent of the Holder of each
Outstanding Security affected thereby, (a) change the Stated Maturity of the
principal of, or any installment of principal of or interest on, any Debt
Security, (b) reduce the principal amount of, or any premium or interest on,
any Debt Security, (c) reduce the amount of principal of an Original Issue
Discount Security or any other Debt Security payable upon acceleration of the
Maturity thereof, (d) change the place or currency of payment of principal of,
or any premium or interest on, any Debt Security, (e) impair the right to
institute suit for the enforcement of any payment on or with respect to any
Debt Security, (f) in the case of Subordinated Debt Securities, modify the
subordination provisions in a manner adverse to the Holders of the Subordinated
Debt Securities, (g) reduce the percentage in principal amount of Outstanding
Securities of any series, the consent of whose Holders is required for
modification or amendment of the Indentures, (h) reduce the percentage in
principal amount of Outstanding Securities of any series necessary for waiver
of compliance with certain provisions of the Indentures or for waiver of
certain defaults or (i) modify such provisions with respect to modification and
waiver. (Section 902)

         The Indentures will provide that the Holders of a majority in
aggregate principal amount of the Outstanding Securities of any series may
waive, on behalf of the Holders of all Debt Securities of such series,
compliance by the Company with certain restrictive provisions of the
Indentures. (Sections 1010 and 1008 of the Senior Indenture and the
Subordinated Indenture, respectively) The Holders of a majority in principal
amount of the Outstanding Securities of any series may waive any past default
under the Indentures, except a default in the payment of principal, premium or
interest and certain covenants and provisions of the Indentures which cannot be
amended without the consent of the Holder of each Outstanding Security of such
series affected. (Section 513)




                                      15
<PAGE>   17
         The Indentures will provide that in determining whether the Holders of
the requisite principal amount of the Outstanding Securities have given or
taken any direction, notice, consent, waiver or other action under the
Indentures as of any date, (i) the principal amount of an Original Issue
Discount Security that will be deemed to be Outstanding will be the amount of
the principal thereof that would be due and payable as of such date upon
acceleration of the Maturity thereof to such date, (ii) if, as of such date,
the principal amount payable at the Stated Maturity of a Debt Security is not
determinable (for example, because it is based on an index), the principal
amount of such Debt Security deemed to be Outstanding as of such date will be
an amount determined in the manner prescribed for such Debt Security and (iii)
the principal amount of a Debt Security denominated in one or more foreign
currencies or currency units that will be deemed to be Outstanding will be the
U.S. dollar equivalent, determined as of such date in the manner prescribed for
such Debt Security, of the principal amount of such Debt Security (or, in the
case of a Debt Security described in clause (i) or (ii) above, of the amount
described in such clause).  Certain Debt Securities, including those for whose
payment or redemption money has been deposited or set aside in trust for the
Holders and those that have been fully defeased pursuant to Section 1302, will
not be deemed to be Outstanding. (Section 101)

         Except in certain limited circumstances, the Company will be entitled
to set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give or take any direction,
notice, consent, waiver or other action under the Indentures, in the manner and
subject to the limitations provided in the Indentures.  In certain limited
circumstances, the Trustee will be entitled to set a record date for action by
Holders.  If a record date is set for any action to be taken by Holders of a
particular series, such action may be taken only by persons who are Holders of
Outstanding Securities of that series on the record date.  To be effective,
such action must be taken by Holders of the requisite principal amount of such
Debt Securities within a specified period following the record date.  For any
particular record date, this period will be 180 days or such other shorter
period as may be specified by the Company (or the Trustee, if it set the record
date), and may be shortened or lengthened (but not beyond 180 days) from time
to time. (Section 104)

DEFEASANCE AND COVENANT DEFEASANCE

         If and to the extent indicated in the applicable Prospectus
Supplement, the Company may elect, at its option at any time, to have the
provisions of Section 1302, relating to defeasance and discharge of
indebtedness, or Section 1303, relating to defeasance of certain restrictive
covenants in the Indentures, applied to the Debt Securities of any series, or
to any specified part of a series. (Section 1301)

   
         Defeasance and Discharge.  The Indentures will provide that, upon the
Company's exercise of its option (if any) to have Section 1302 applied to any
Subordinated Debt Securities, the provisions of Article Fifteen of the
Subordinated Indenture relating to subordination will cease to be effective and,
with respect to any Debt Securities, the Company will be discharged from all its
obligations with respect thereto (except for certain obligations to exchange or
register the transfer of Debt Securities, to replace stolen, lost or mutilated
Debt Securities, to maintain paying agencies, to hold moneys for payment in
trust and, if applicable, to effect conversion of Debt Securities) upon the
deposit in trust for the benefit of the Holders of such Debt Securities of money
or U.S. Government Obligations, or both, which, through the payment of principal
and interest in respect thereof in accordance with their terms, will provide
money in an amount sufficient to pay the principal of and any premium and
interest on such Debt Securities on the respective Stated Maturities in
accordance with the terms of the Indentures and such Debt Securities.  Such
defeasance or discharge may occur only if, among other things, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that
    




                                      16
<PAGE>   18
the Company has received from, or there has been published by, the United
States Internal Revenue Service a ruling, or there has been a change in tax
law, in either case to the effect that Holders of such Debt Securities will not
recognize gain or loss for federal income tax purposes as a result of such
deposit, defeasance and discharge and will be subject to federal income tax on
the same amount, in the same manner and at the same times as would have been
the case if such deposit, defeasance and discharge were not to occur. (Sections
1302 and 1304)

            
         Defeasance of Certain Covenants.  The Indentures will provide that,
upon the Company's exercise of its option (if any) to have Section 1303 applied
to any Debt Securities, the Company may omit to comply with certain restrictive
covenants, including those described under "Restrictive Covenants" and any that
may be described in the applicable Prospectus Supplement, and the occurrence of
certain Events of Default, which are described above in clause (d) (with respect
to such restrictive covenants) under "Events of Default" and any that may be
described in the applicable Prospectus Supplement, will be deemed not to be or
result in an Event of Default, in each case with respect to such Debt
Securities, and, in the case of the Subordinated Indenture, the provisions of
Article Fifteen relating to subordination will cease to be effective with
respect to any Subordinated Debt Securities.  The Company, in order to exercise
such option, will be required to deposit, in trust for the benefit of the
Holders of such Debt Securities, money or U.S. Government Obligations, or both,
which, through the payment of principal and interest in respect thereof in
accordance with their terms, will provide money in an amount sufficient to pay
the principal of and any premium and interest on such Debt Securities on the
respective Stated Maturities in accordance with the terms of the Indentures and
such Debt Securities.  The Company will also be required, among other things, to
deliver to the Trustee an Opinion of Counsel to the effect that Holders of such
Debt Securities will not recognize gain or loss for federal income tax purposes
as a result of such deposit and defeasance of certain obligations and will be
subject to federal income tax on the same amount, in the same manner and at the
same times as would have been the case if such deposit and defeasance were not
to occur.  In the event the Company exercised this option with respect to any
Debt Securities and such Debt Securities were declared due and payable because
of the occurrence of any Event of Default, the amount of money and U.S.
Government Obligations so deposited in trust would be sufficient to pay amounts
due on such Debt Securities at the time of their respective Stated Maturities
but may not be sufficient to pay amounts due on such Debt Securities upon any
acceleration resulting from such Event of Default.  In such case, the Company
would remain liable for such payments. (Sections 1303 and 1304)
    

   
        The Company may, at its option, satisfy and discharge each of the
Indentures (except for certain obligations of the Company and the Trustee,
including, among others the obligations to apply money held in trust) when (i)
either (a) all Debt Securities under such Indenture previously authenticated and
delivered (other than (1) Debt Securities that were destroyed, lost or stolen
and that have been replaced or paid and (2) Debt Securities for the payment of
which money has been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust) have
been delivered to the Trustee for cancellation or discharge from such trust)
have been delivered to the Trustee for cancellation or (b) all such Debt
Securities under such Indenture not theretofore delivered to the Trustee for
cancellation (1) have become due and payable, (2) will become due and payable at
their Stated Maturity within one year, or (3) 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 has deposited or caused to be deposited with the
Trustee as trust funds in trust for such purpose an amount sufficient to pay and
discharge the entire indebtedness on such Debt Securities under such Indenture
not previously delivered to the Trustee for cancellation, for principal and any
premium and interest to the date of such deposit (in the case of Debt Securities
under such Indenture which have become due and payable) or to the Stated
Maturity or redemption date as the case may be, (ii) the Company has paid or
caused to be paid all other sums payable under such Indenture by the Company,
and (iii) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each to the effect that all conditions precedent relating
to the satisfaction and discharge of such Indenture have been satisfied. 
    

NOTICES

         Notices to Holders of Debt Securities will be given by mail to the
addresses of such Holders as they may appear in the Security Register.
(Sections 101 and 106)

TITLE

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name a Debt Security is registered as the
absolute owner thereof (whether or not such Debt Security may be overdue) for
the purpose of making payment and for all other purposes.  (Section 308)

GOVERNING LAW




                                      17
<PAGE>   19
         The Indentures and the Debt Securities will be governed by, and
construed in accordance with, the law of the State of New York.  (Section 112)

   
REGARDING THE TRUSTEE

        The Indentures contain certain limitations on the right of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize for its own account on certain property received in
respect of any such claim as security or otherwise. (Section 613) The Trustee
is permitted to engage in certain other transactions; however, if it acquires
any conflicting interest and there is a default under the Securities of any
series for which the Trustee serves as trustee, the Trustee must eliminate such
conflict or resign. (Section 608)

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

        The authorized capital stock of the Company consists of 160,000,000
shares of common stock, $0.0001 par value per share ("Common Stock"), and
4,000,000 shares of preferred stock, $0.0001 par value per share (the
"Preferred Stock"). Of such shares of Preferred Stock, 116,000 shares are
designated as Series A Participating Preferred Stock (the "Series A
Preferred"). As of March 27, 1997, there were 47,334,858 shares of Common Stock
issued and outstanding and no shares of Preferred Stock issued and outstanding.
The following summary is qualified in its entirety by reference to the
Company's Charter and Bylaws.

COMMON STOCK

         The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding Preferred Stock, the holders of Common Stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the Board of Directors out of funds legally available therefor. In
the event of a liquidation, dissolution or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of liabilities, subject to the prior liquidation rights of the
Preferred Stock, if any, then outstanding. The Common Stock has no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the Common Stock. All outstanding shares
of Common Stock are fully paid and non-assessable.

PREFERRED STOCK

         The Board of Directors has designated 116,000 shares of the Preferred
Stock as Series A Preferred. See "Preferred Share Rights." The Board of
Directors has the authority to issue any undesignated shares of Preferred Stock
in one or more series and to fix the rights, preferences, privileges,
qualifications, limitations and restrictions thereof, including dividend rights,
voting rights, terms of redemption, redemption prices, liquidation preferences
and the number of shares constituting any series or the designation of such
series, without any further vote or action by the stockholders. The issuance of
Preferred Stock may have the effect of delaying or preventing a change in
control of the Company without further action by the stockholders. The issuance
of Preferred Stock with voting and conversion rights may adversely affect the
voting power of the holders of Common Stock, including the loss of voting
control to others. The Company has no present plans to issue any of the
Preferred Stock except pursuant to the Rights described below.

PREFERRED SHARE RIGHTS

   
        On March 3, 1997, pursuant to a Preferred Shares Rights Agreement, (the
"Rights Agreement") between the Company and ChaseMellon Shareholder Services,
L.L.C., as Rights Agent (the "Rights Agent"), the Company's Board of Directors
declared a dividend of one right (a "Right") to purchase one one-thousandth
share of the Company's Series A Preferred for each outstanding share of Common
Stock. The dividend is payable on March 17, 1997 (the "Record Date") to
stockholders of record as of the close of business on that day. Each Right
entitles the registered holder to purchase from the Company one one-thousandth
of a share of Series A Preferred at an exercise price of $150.00 (the "Purchase
Price"), subject to adjustment.
    

   
        The following summary of the principal terms of the Rights Agreement is
a general description only and is subject to the detailed terms and conditions
of the Rights Agreement, a copy of which is filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
    

   
         Rights Evidenced by Common Share Certificates. The Rights will not be
exercisable until the Distribution Date (defined below). Certificates for the
Rights ("Rights Certificates") will not be sent to stockholders and the Rights
will attach to and trade only together with the Common Shares. Accordingly,
Common Share certificates outstanding on the Record Date will evidence the
Rights related thereto, and Common Share certificates issued after the Record
Date will contain a notation incorporating the Rights Agreement by reference.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the surrender or transfer of any certificates for Common Shares outstanding as
of the Record Date will also constitute the transfer of the Rights associated
with the Common Shares represented by such certificate.
    


                                      19
<PAGE>   21
         Distribution Date. The Rights will separate from the Common Shares,
Rights Certificates will be issued and the Rights will become exercisable upon
the earlier of: (i) ten (10) days (or such later date as may be determined by
the Board of Directors) following a public announcement that a person or group
of affiliated or associated persons (an "Acquiring Person") has acquired, or
obtained the right to acquire, beneficial ownership of 20% or more of the
outstanding Common Shares, or (ii) ten (10) business days (or such later date as
may be determined by the Board of Directors) following the commencement of, or
announcement of an intention to make, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of 20% or more of the outstanding Common Shares. The earlier of such dates
is referred to as the "Distribution Date."

         Issuance of Rights Certificates; Expiration of Rights. As soon as
practicable following the Distribution Date, separate Rights Certificates will
be mailed to holders of record of the Common Shares as of the close of business
on the Distribution Date and such separate Rights Certificates alone will
evidence the Rights from and after the Distribution Date. The Rights will expire
on the earliest of (i) March 17, 2007 (the "Final Expiration Date") or (ii)
redemption or exchange of the Rights as described below.

         Initial Exercise of the Rights. Following the Distribution Date, and
until one of the further events described below, holders of the Rights will be
entitled to receive, upon exercise and the payment of the Purchase Price, one
one-thousandth of a share of Series A Preferred.

         Right to Buy Company Common Shares. Unless the Rights are earlier
redeemed, in the event that an Acquiring Person becomes the beneficial owner of
20% or more of the Company's Common Shares then outstanding, then proper
provision will be made so that each holder of a Right which has not theretofore
been exercised (other than Rights beneficially owned by the Acquiring Person or
any affiliate of the Acquiring Person, which will thereafter be void) will
thereafter have the right to receive, upon exercise, Common Shares having a
value equal to two times the Purchase Price. In the event that the Company does
not have sufficient Common Shares available for all Rights to be exercised, or
the Board decides that such action is necessary and not contrary to the
interests of Rights holders, the Company may instead substitute cash, assets or
other securities for the Common Shares for which the Rights would have been
exercisable.

         Right to Buy Acquiring Company Stock. Similarly, unless the Rights are
earlier redeemed, in the event that, after an Acquiring Person becomes the
beneficial owner of 20% or more of the Company's Common Shares then outstanding,
(i) the Company is acquired in a merger or other business combination
transaction, or (ii) 50% or more of the Company's consolidated assets or earning
power are sold (other than in transactions in the ordinary course of business),
each holder of a Right which has not previously been exercised (other than
Rights beneficially owned by the Acquiring Person or any affiliate of the
Acquiring Person, which will thereafter be void) will thereafter have the right
to receive, upon exercise, shares of common stock of the acquiring company
having a value equal to two times the Purchase Price.

         Exchange Provision. At any time after the acquisition by an Acquiring
Person of beneficial ownership of 20% or more of the Company's outstanding
Common Shares and prior to the acquisition by any person or entity of beneficial
ownership of 50% or more of the Company's outstanding Common Shares, the Board
of Directors of the Company may exchange the Rights (other than Rights owned by
the Acquiring Person), in whole or in part, at an exchange ratio of one Common
Share per Right.

         Redemption. At any time on or prior to the close of business on the
earlier of (i) the tenth day following the acquisition by an Acquiring Person of
beneficial ownership of 20% or more of the Company's Common Shares or such later
date as may be determined by the Board of Directors and publicly announced by
the Company, or (ii) the Final Expiration Date of the Rights, the Company may
redeem the Rights in whole, but not in part, at a price of $0.001 per Right.

         Adjustments to Prevent Dilution. The Purchase Price payable, the number
of Rights, and the number of shares of Series A Preferred or Common Shares or
other securities or property issuable upon exercise of the Rights are subject to
adjustment from time to time in connection with certain dilutive issuances by
the Company as set forth in the Rights Agreement. With certain exceptions, no
adjustment in the Purchase Price will be required until cumulative adjustments
require an adjustment of at least 1% in such Purchase Price.

         Cash Paid Instead of Issuing Fractional Shares. No fractional portion
less than integral multiples of one Common Share or one one-thousandth of a
share of Series A Preferred will be issued upon exercise of a Right and in lieu
thereof, an adjustment in cash will be made based on the market price of the
security to be so issued on the last trading date prior to the date of exercise.



                                      20

         No Stockholders' Rights Prior to Exercise. Until a Right is exercised,
the holder thereof, as such, will have no rights as a stockholder of the Company
(other than any rights resulting from such holder's ownership of Common Shares),
including, without limitation, the right to vote or to receive dividends.

         Amendment of Rights Agreement. The provisions of the Rights Agreement
may be supplemented or amended by the Board of Directors in any manner prior to
the close of business on the date the Rights separate from the Common Shares and
become exercisable. After such date, the provisions of the Rights Agreement may
be amended by the Board in order to cure any ambiguity, defect or inconsistency,
to make changes which do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person), or to shorten or lengthen any
time period under the Rights Agreement; provided, however, that no amendment to
adjust the time period governing redemption shall be made at such time as the
Rights are not redeemable.

         Rights and Preferences of the Series A Preferred. Series A Preferred
purchasable upon exercise of the Rights will not be redeemable. Each share of
Series A Preferred will be entitled to an aggregate dividend of 1,000 times the
dividend declared per Common Share. In the event of liquidation, the holders of
the Series A Preferred will be entitled to 1,000 times the amount paid per
Common Share plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not declared, to the date of such payment.
Each share of Series A Preferred will have 1,000 votes, voting together with the
Common Shares. These rights are protected by customary anti-dilution provisions.

         Because of the nature of the dividend, liquidation and voting rights of
the shares of Series A Preferred, the value of the one one-thousandth interest
in a share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.

        Certain Anti-takeover Effects. The Rights may have the effect of
rendering more difficult or discouraging an acquisition of the Company deemed
undesirable by the Board of Directors. The Rights may cause substantial
dilution to a person or group that attempts to acquire the Company on terms or
in a manner not approved by the Company's Board of Directors, except pursuant
to an offer conditioned upon the negation, purchase or redemption of the
Rights.

ANTI-TAKEOVER EFFECTS OF DELAWARE LAW

   
         The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("Section 203"), which, subject to certain exceptions,
prohibits a Delaware corporation from engaging in any business combination with
any interested stockholder for a period of three (3) years following the time
that such stockholder became an interested stockholder, unless: (i) prior to
such time, the Board of Directors of the corporation approved either the
business combination or the transaction that resulted in the stockholder
becoming an interested stockholder; (ii) upon consummation of the transaction
that resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes
    




                                      21
<PAGE>   23
   
of determining the number of shares outstanding those shares owned (a) by
persons who are directors and also officers and (b) by employee stock plans in
which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer, or (iii) at or subsequent to such time, the business combination is
approved by the Board of Directors and authorized at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
at least 66-2/3% of the outstanding voting stock that is not owned by the
interested stockholder.
    

         Section 203 defines "business combination" to include: (i) any merger
or consolidation involving the corporation and the interested stockholder, (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets of
the corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided by or through the corporation. In
general, Section 203 defines an "interested stockholder" as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.

                              PLAN OF DISTRIBUTION

         The Company may sell the Securities separately or together, (i) to one
or more underwriters or dealers for public offering and sale by them and (ii) to
investors directly or through agents. The distribution of the Securities may be
effected from time to time in one or more transactions at a fixed price or
prices (which may be changed 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. Each Prospectus Supplement will describe the method of
distribution of the Securities offered thereby.

         In connection with the sale of the Securities, underwriters, dealers or
agents may receive compensation from the Company or from purchasers of the
Securities for whom they may act as agents, in the form of discounts,
concessions or commissions. The underwriters, dealers or agents which
participate in the distribution of the Securities may be deemed to be
underwriters under the Securities Act and any discounts or commissions received
by them and any profit on the resale of the Securities received by them may be
deemed to be underwriting discounts and commissions thereunder. Any such
underwriter, dealer or agent will be identified and any such compensation
received from the Company will be described in the Prospectus Supplement. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.

         Under agreements that may be entered into with the Company,
underwriters, dealers and agents may be entitled to indemnification by the
Company against certain civil liabilities, including liabilities under the
Securities Act, or to contribution with respect to payments which the
underwriters, dealers or agents may be required to make in respect thereof.

         The Company may grant underwriters who participate in the distribution
of Securities an option to purchase additional Securities to cover
over-allotments, if any.

         Certain of the underwriters or agents and their associates may be
customers of, engage in transactions with or perform services for the Company in
the ordinary course of business.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law ("Delaware Law")
authorizes a court to award or a corporation's Board of Directors to grant
indemnification to directors and officers in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended. The registrant's Bylaws provide for indemnification of its
directors, officers, employees and other agents to the maximum extent permitted
by Delaware Law. The registrant has entered into indemnification agreements with
its directors and certain of its officers. The indemnification agreements
provide the registrant's directors and elected officers with further
indemnification to the maximum extent permitted by Delaware Law.

   
         Reference is made to the form of Underwriting Agreement (Common Stock)
and Underwriting Agreement (Debt Securities) and form of Underwriting Agreement
(Convertible Securities) filed as Exhibits 1.1, Exhibit 1.2 and 1.3,
respectively, to this registration statement for certain provisions regarding
indemnification of officers and directors of the registrant by the several
Underwriters.

ITEM 17.  UNDERTAKINGS

     1.        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 of 1933 (the "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 end 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 a 20%
               change in the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               registration statement; and

                    (iii)To include any material information with respect to the
               plan of distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement;

     provided, however, that the undertakings set forth in clauses (i) and (ii)
     above shall not apply if the information required to be included in a
     post-effective amendment by these clauses is contained in periodic reports
     filed by the registrant pursuant to Section 13 or Section 15(d) of the
     Securities Exchange Act of 1934 (the "Exchange Act") that are incorporated
     by reference in this registration statement.

               (2) That, for the purpose of determining any liability under the
     Act, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     2. The undersigned registrant hereby undertakes, that, for purposes of
determining any liability under the Act, each filing of the registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act 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.

     3. Insofar as indemnification of liabilities arising under the Act 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 Act
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 Act and will be governed by the final adjudication of
such issue.

     4.        The undersigned registrant hereby undertakes that:

               (a) For purposes of determining any liability under the Act, the
     information omitted from the form of prospectus filed as part of this
     registration statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be part of this registration
     statement as of the time it was declared effective.

<PAGE>   27
               (b) For the purpose of determining any liability under the Act,
     each post-effective amendment that contains a form of prospectus 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.

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing this Amendment to Form S-3 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Milpitas, State of California, on May 12, 1997.

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

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Indenture to be given, made or
taken by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. The
Trustee shall promptly deliver to the Company copies of all such instrument or
instruments and records delivered to the Trustee. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section.

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

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

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

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

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

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





                                      -9-
<PAGE>   17
record date set pursuant to this Section, the party hereto which set such
record date shall be deemed to have initially designated the 180th day after
such record date as the Expiration Date with respect thereto, subject to its
right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date.

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

SECTION 105.     NOTICES, ETC., TO TRUSTEE AND 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 (or by facsimile transmissions ((213) 362-7357), provided that oral
confirmation of receipt shall have been received) to or with the Trustee at its
Corporate Trust Office, Attention: Corporate Trust Department, 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 instrument or at any other address previously furnished in
writing to the Trustee by the Company, Attention:  Chief Financial Officer.

SECTION 106.     NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at its address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

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

SECTION 107.     CONFLICT WITH TRUST INDENTURE ACT.

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

SECTION 108.     EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

SECTION 109.     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 110.     SEPARABILITY CLAUSE.

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

SECTION 111.     BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

SECTION 112.     GOVERNING LAW.

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

SECTION 113.     LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert a Security at a particular conversion price shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) or, if applicable to a
particular series of Securities, conversion need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, at the Stated Maturity or on such last day for
conversion, as the case may be.

SECTION 114.     INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

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

of business on a Regular Record Date and ending at the opening of business on
the Interest Payment Date next following such Regular Record Date (unless this
Security or the portion being converted shall have been called for redemption on
a Redemption Date during the period beginning at the close of business on a
Regular Record Date and ending at the opening of business on the first Business
Day after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day), also be accompanied
by payment in funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of this Security
then being converted. Subject to the aforesaid requirement for payment and, in
the case of a conversion after the Regular Record Date next preceding any
Interest Payment Date and on or before such Interest Payment Date, to the right
of the Holder of this Security (or any Predecessor Security) of record at such
Regular Record Date to receive an installment of interest (with certain
exceptions provided in the Indenture), no adjustment is to be made on conversion
for interest accrued hereon or for dividends on shares of Common Stock issued on
conversion.  The Company is not required to issue fractional shares upon any
such conversion, but shall make adjustment therefor in cash on the basis of the
current market value of such fractional interest as provided in the Indenture.
The conversion price is subject to adjustment as provided in the Indenture. In
addition, the Indenture provides that in case of certain consolidations or
mergers to which the Company
    





                                      -15-
<PAGE>   23
is a party or the sale of substantially all of the assets of the Company, the
Indenture shall be amended, without the consent of any Holders of Securities,
so that this Security, if then outstanding, will be convertible thereafter,
during the period this Security shall be convertible as specified above, only
into the kind and amount of securities, cash and other property receivable upon
the consolidation, merger or sale by a holder of the number of shares of Common
Stock into which this Security might have been converted immediately prior to
such consolidation, merger or sale (assuming such holder of Common Stock failed
to exercise any rights of election and received per share the kind and amount
received per share by a plurality of non-electing shares). In the event of
conversion of this Security in part only, a new Security or Securities for the
unconverted portion hereof shall be issued in the name of the Holder hereof
upon the cancellation hereof.]

         [IF THE SECURITY IS CONVERTIBLE INTO OTHER SECURITIES OF THE COMPANY,
SPECIFY THE CONVERSION FEATURES.]

         [IF THE SECURITY IS NOT AN ORIGINAL ISSUE DISCOUNT SECURITY, INSERT --
If an Event of Default with respect to Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.]

         [IF THE SECURITY IS AN ORIGINAL ISSUE DISCOUNT SECURITY, INSERT -- If
an Event of Default with respect to Securities of this series shall occur and
be continuing, an amount of principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture. Such amount shall be equal to -- insert formula for determining the
amount.  Upon payment (i) of the amount of principal so declared due and
payable and (ii) of interest on any overdue principal, premium and interest (in
each case to the extent that the payment of such interest shall be legally
enforceable), all of the Company's obligations in respect of the payment of the
principal of and premium and interest, if any, on the Securities of this series
shall terminate.]

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of more than 50% in principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee
or for any other remedy thereunder, unless such Holder shall have previously
given the Trustee written notice of a continuing Event of Default with respect
to the Securities of this series, the Holders of not less than 25% in principal
amount of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and
the Trustee shall not have received from the Holders of a majority in principal
amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

currency, herein prescribed.

attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

in addition to or in lieu of those set forth in Clause (2) of the last
paragraph of Section 305 in which any such Global Security may be exchanged in

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

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

SECTION 302.      DENOMINATIONS.

         The Securities of each series shall be issuable only in registered
form without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination

shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303.      EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

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

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the 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.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order





                                      -21-
<PAGE>   29
   
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, a copy of such Board Resolution,
the Officers' Certicate setting forth the terms of the series and an Opinion
of Counsel, with such Opinion of Counsel stating,
    

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

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

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

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

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

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section
309, for all purposes of this Indenture such Security shall be deemed never to
have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture.

SECTION 304.      TEMPORARY SECURITIES.

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





                                      -22-
<PAGE>   30
         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, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations and
of like tenor and aggregate principal amount. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of such series and tenor.

SECTION 305.      REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

         Upon surrender for registration of transfer of any Security of a
series at the office or agency of the 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 Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.

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

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

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

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

         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at

and ending

at the close of business on the day of such mailing, or (B) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

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

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

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

         (3)     Subject to Clause (2) above, any exchange of a Global Security
for other Securities may be made in whole or in part, and all Securities issued
in exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

         (4)     Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security or any
portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
1107 or otherwise, shall be authenticated and delivered in the form of, and
shall be, a Global Security, unless such Security is registered in the name of
a Person other than the Depositary for such Global Security or a nominee
thereof.

SECTION 306.      MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

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

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

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





                                      -24-
<PAGE>   32
         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.

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

SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

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

         (1)     The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Security of
such series and the date of the proposed payment, and at the same time the
Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit prior to
the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such Defaulted Interest as in this
Clause provided. Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest which shall be not more than 15 days and not
less than 10 days prior to the date of the proposed payment and not less than
10 days after the receipt by the Trustee of the notice of the proposed payment.
The Trustee shall promptly notify the Company of such Special Record Date and,
in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date
therefor to be given to each Holder of Securities of such series in the manner
set forth in Section 106, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on
such Special Record Date and shall no longer be payable pursuant to the
following Clause (2).

         (2)     The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which 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, 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.





                                      -25-
<PAGE>   33
         Subject to the provisions of Section 1402, in the case of any Security
(or any part thereof) which is converted after any Regular Record Date and on
or prior to the next succeeding Interest Payment Date (other than any Security
the principal of (or premium, if any, on) which shall become due and payable,
whether at Stated Maturity or by declaration of acceleration prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding
such conversion and such interest (whether or not punctually paid or duly
provided for) shall be paid to the Person in whose name that Security (or any
one or more Predecessor Securities) is registered at the close of business on
such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence or in Section 1402, in the case of any Security
(or any part thereof) which is converted, interest whose Stated Maturity is
after the date of conversion of such Security (or such part thereof) shall not
be payable.

SECTION 308.      PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309.      CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The 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 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 canceled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted by this Indenture. All canceled
Securities held by the Trustee shall be disposed of as directed by a Company
Order.

SECTION 310.     COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                           SATISFACTION AND DISCHARGE

SECTION 401.      SATISFACTION AND DISCHARGE OF INDENTURE.

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





                                      -26-

         (1)     either

                 (A)      all Securities theretofore authenticated and
         delivered (other than (i) Securities which have been destroyed, lost
         or stolen and which have been replaced or paid as provided in Section
         306 and (ii) Securities for whose payment money 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 such Securities not theretofore delivered to the 
         Trustee for cancellation

                                        (i)     have become due and payable, or

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

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

         in the case of (i), (ii) or (iii) above, has deposited or caused to be
         deposited with the Trustee as trust funds in trust for the purpose
         money in an amount sufficient to pay and discharge the entire
         indebtedness on such Securities not theretofore delivered to the
         Trustee for cancellation, for principal and any premium and interest
         to the date of such deposit (in the case of Securities which have
         become due and payable) or to the Stated Maturity or Redemption Date,
         as the case may be;

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

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

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

SECTION 402.      APPLICATION OF TRUST MONEY.

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

any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be

specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and
continuance of such default or breach for a period of 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)     the entry by a court having jurisdiction in the premises of
(A) a decree or order for relief in respect of the Company in an involuntary
case or proceeding under any applicable Federal or State bankruptcy,
insolvency, reorganization or other similar law or (B) a decree or order
adjudging the Company a bankrupt or insolvent, or approving as properly filed a
petition seeking reorganization, arrangement, adjustment or composition of or

order unstayed and in effect for a period of 90 consecutive days; or

         (6)     the commencement by the Company of a voluntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,

it in writing of its inability to pay its debts generally as they become due,
or the taking of corporate action by the Company in furtherance of any such
action; or

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

SECTION 502.     ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable. If an Event of Default
specified in Section 501(5) or 501(6) with respect to Securities of any series
at the time Outstanding occurs, the principal amount of all the Securities of
that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, 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 and its consequences if

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

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

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

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

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

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

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

SECTION 503.     COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                 TRUSTEE.

         The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

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

SECTION 504.      TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,





                                      -30-
<PAGE>   38
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.      APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any
premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

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

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

SECTION 507.      LIMITATION ON SUITS.

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

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

         (2)     the Holders of not less than 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 reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

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

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

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

SECTION 508.      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM
                  AND INTEREST AND TO CONVERT.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section
307)

interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert
such Securities in accordance with Article Fourteen and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510.     RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.

SECTION 511.     DELAY OR OMISSION NOT WAIVER.

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

SECTION 512.     CONTROL BY HOLDERS.

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

   
         (1)     such direction shall not be in conflict with any rule of law 
or with this Indenture and the Trustee shall not have determined that the
action so directed would be unjustly prejudicial to Holders of Securities of
that series, or any other series, not taking part in such direction, and
    

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

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 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 any premium or interest
on any Security of such series, or





                                      -32-
<PAGE>   40
         (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 impair any right consequent thereon.

SECTION 514.     UNDERTAKING FOR COSTS.

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

SECTION 515.     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.

                                  ARTICLE SIX

                                  THE TRUSTEE

SECTION 601.      CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.

SECTION 602.      NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice
of such default as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified
in Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof.
For the purpose of this Section, the term "default" means any event which is,
or after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

SECTION 603.      CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

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

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

         (3)     whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its
part, rely upon an Officers' Certificate;

         (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 pursuant to this Indenture, unless such Holders shall
have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

         (6)     the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled
to examine the books, records and premises of the Company, personally or by
agent or attorney; and

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

SECTION 604.      NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, 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. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.





                                      -34-
<PAGE>   42
SECTION 605.      MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

         Subject to the limitations imposed by the Trust Indenture Act, nothing
in this Indenture shall prohibit the Trustee from becoming and acting as
trustee under other indentures under which other securities, or certificates of
interest of participation in other securities, of the Company are outstanding
in the same manner as if it were not Trustee hereunder.

SECTION 606.      MONEY HELD IN TRUST.

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

SECTION 607.      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
the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of
this Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

         (3)     to indemnify the 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.

SECTION 608.      CONFLICTING INTERESTS.

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

SECTION 609.      CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is





                                      -35-
<PAGE>   43
   
eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company, its bank holding company has) a
combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.
    

SECTION 610.     RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

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

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

         If at any time:

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

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

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

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

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series) and shall comply with
the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall





                                      -36-
<PAGE>   44
   
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 in accordance with the applicable requirements of Section
611, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 611, the retiring Trustee may petition, or any Holder
who has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.
    

         The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series to all
Holders of Securities of such series in the manner provided in Section 106.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

SECTION 611.     ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the 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 the 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.

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





                                      -37-
<PAGE>   45
         Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in the
first or second preceding paragraph, as the case may be.

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

SECTION 612.     MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 613.     PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

SECTION 614.     APPOINTMENT OF AUTHENTICATING AGENT.

   
         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 original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having (or if the Authenticating Agent is a member of a bank holding
company system, its bank holding company has) a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal
or State authority. If such Authenticating Agent publishes reports of condition
at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.
    

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise





                                      -38-
<PAGE>   46
eligible under this Section, without the execution or filing of any paper or
any further act on the part of the Trustee or the Authenticating Agent.

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

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section 612, the Securities of such series may have endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

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

                                        STATE STREET BANK AND TRUST COMPANY OF

SECTION 701.      COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF HOLDERS.

         The Company will furnish or cause to be furnished to the Trustee

and addresses of the Holders of Securities of each series as of such Regular

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
such list is furnished;





                                      -39-

provided that no such list need be furnished by the Company to the Trustee so
long as the Trustee is acting as Security Registrar.

SECTION 702.      PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

         The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.

         Upon any consolidation of the Company with, or merger of the Company

power of, the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein, and thereafter, except
in the case of a lease, the predecessor Person shall be relieved of all
obligations and covenants under this Indenture and the Securities.

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

Securities in uncertificated form; or

         (5)     to add to, change or eliminate any of the provisions of this

<PAGE>   50
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

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

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

         (3)     modify any of the provisions of this Section, Section 513 or
Section 1010, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the

however, that this clause shall not be deemed to require the consent of any
Holder with respect to changes in the references to "the Trustee" and
concomitant changes in this Section and Section 1010, or the deletion of this
proviso, in accordance with the requirements of Sections 611 and 901(8), or

         (4)     if applicable, make any change that adversely affects the
right to convert any security as provided in Article Fourteen or pursuant to
Section 301 (except as permitted by Section 901(9)) or decrease the conversion
rate or increase the conversion price of any such security.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

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

SECTION 903.      EXECUTION OF SUPPLEMENTAL INDENTURES.

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

relying upon, an Opinion of Counsel stating that the execution of such

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

SECTION 906.      REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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

                                  ARTICLE TEN

                                   COVENANTS

SECTION 1001.    PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

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

SECTION 1002.    MAINTENANCE OF OFFICE OR AGENCY.

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

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment 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.

<PAGE>   52
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 Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal and any premium and interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the 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) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

   
         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; 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 a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in each Place of Payment, 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.    STATEMENT BY OFFICERS AS TO DEFAULT.

   
         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers
thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. The fiscal year of the Company
currently ends on December 31; and the Company will give prompt written notice
of any change of its fiscal year.

SECTION 1005.    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 existence.

SECTION 1006.    MAINTENANCE OF PROPERTIES.

   
         The Company will cause all properties used or useful in the conduct of
its business 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, and to the extent, 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 nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.
    

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 the Company upon the income,
profits or property of the Company, 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; 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 (i) whose amount, applicability or validity is
being contested in good faith by appropriate proceedings or (ii) if the failure
to pay or discharge would not have a material adverse effect on the assets,
business, operations, properties or condition (financial or otherwise) of the
Company and its Subsidiaries, taken as a whole. 
    

SECTION 1008.    LIMITATION ON LIENS.

         The Company will not issue, incur, create, assume or guarantee, and
will not permit any Restricted Subsidiary to issue, incur, create, assume or
guarantee, any debt for borrowed money secured by a mortgage, security
interest, pledge, lien, charge or other encumbrance ("mortgages") upon any
Principal Property of the Company or any Restricted Subsidiary or upon any
shares of stock or indebtedness of any Restricted Subsidiary (whether such
Principal Property, shares or indebtedness are now existing or owned or
hereafter created or acquired) without in any such case effectively providing
concurrently with issuance, incurrence, creation, assumption or guarantee of
any such secured debt, or the grant of a mortgage with respect to any such
indebtedness, that the Securities (together with, if the Company shall so
determine, any other indebtedness of or guarantee by the Company or such
Restricted Subsidiary ranking equally with the Securities) shall be secured
equally and ratably with (or, at the option of the Company, prior to) such
secured debt. The foregoing restriction, however, will not apply to:

         (1)     mortgages on property existing at the time of acquisition
thereof by the Company or any Subsidiary, provided that such mortgages were in
existence prior to the contemplation of such acquisitions;

         (2)     mortgages on property, shares of stock or indebtedness or
other assets of any corporation existing at the time such corporation becomes a
Restricted Subsidiary, provided that such mortgages are not incurred in
anticipation of such corporation becoming a Restricted Subsidiary;





                                      -46-
<PAGE>   54
         (3)     mortgages on property, shares of stock or indebtedness
existing at the time of acquisition thereof by the Company or a Restricted
Subsidiary or mortgages thereon to secure the payment of all or any part of the
purchase price thereof, or mortgages on property, shares of stock or
indebtedness to secure any indebtedness for borrowed money incurred prior to,
at the time of or within 270 days after, the latest of the acquisition thereof,
or, in the case of property, the completion of construction, the completion of
improvements, or the commencement of substantial commercial operation of such
property for the purpose of financing all or any part of the purchase price
thereof, such construction, or the making of such improvements;

         (4)     mortgages to secure indebtedness owing to the Company or to a
                 Restricted Subsidiary:

         (5)     mortgages existing at the date of this Indenture;

         (6)     mortgages on property of a corporation existing at the time
such corporation is merged into or consolidated with the Company or a
Restricted Subsidiary or at the time of a sale, lease or other disposition of
the properties of a corporation as an entirety or substantially as an entirety
to the Company or a Restricted Subsidiary, provided that such mortgage was not
incurred in anticipation of such merger or consolidation or sale, lease or
other disposition;

         (7)     mortgages in favor of the United States or any State,
territory or possession thereof (or the District of Columbia), or any
department, agency, instrumentality or political subdivision of the United
States or any State, territory or possession thereof (or the District of
Columbia), to secure partial, progress, advance or other payments pursuant to
any contract or statute or to secure any indebtedness incurred for the purpose
of financing all or any part of the purchase price of the cost of constructing
or improving the property subject to such mortgages;

         (8)     mortgages created in connection with the acquisition of assets
or a project financed with, and created to secure, a Nonrecourse Obligation;

         (9)     extensions, renewals, refinancings or replacements of any
mortgage referred to in the foregoing clauses (1), (2), (3), (4), (5), (6), (7)
and (8) provided, however, that any mortgages permitted by any of the foregoing
clauses (1), (2), (3), (4), (5), (6), (7) and (8) shall not extend to or cover
any property of the Company or such Restricted Subsidiary, as the case may be,
other than the property, if any, specified in such clauses and improvements
thereto, and provided further that any refinancing or replacement of any
mortgages permitted by the foregoing clauses (7) and (8) shall be of the type
referred to in such clauses (7) or (8), as the case may be.

         Notwithstanding the restrictions set forth in the preceding paragraph,
the Company or any Restricted Subsidiary will be permitted to issue, incur,
create, assume or guarantee debt secured by a mortgage which would otherwise be
subject to such restrictions, without equally and ratably securing the
Securities, provided that after giving effect thereto, the aggregate amount of
all debt so secured by mortgages (not including mortgages permitted under
clauses (1) through (10) above) does not exceed 15% of the Consolidated Net
Tangible Assets of the Company as most recently determine on or prior to such
date.

SECTION 1009.    LIMITATIONS ON SALE AND LEASEBACK TRANSACTIONS.

         The Company will not, nor will it permit any Restricted Subsidiary to,
enter into any Sale and Lease-Back Transaction with respect to any Principal
Property, other than any such transaction involving a lease for a term of not
more than three years of any such transaction between the Company and a
Restricted Subsidiary or between Restricted Subsidiaries, unless: (1) the
Company or such Restricted Subsidiary would be entitled to incurs indebtedness
secured by a mortgage on the Principal Property involved in such transaction at
least equal in amount to the Attributable Debt





                                      -47-
<PAGE>   55
with respect to such Sale and Lease-Back Transaction, without equally and
ratably securing the Securities, pursuant to Section 1008; or (2) the Company
shall apply an amount equal to the greater of the net proceeds of such sale or
the Attributable Debt with respect to such Sale and Lease-Back Transaction
within 180 days of such sale to either (or a combination of) the retirement
(other than mandatory retirement, mandatory prepayment or sinking fund payment
or by a payment at maturity) of debt for borrowed money of the Company or a
Restricted Subsidiary that matures more than 12 months after the creation of
such indebtedness or the purchase, construction or development of other
comparable property.

SECTION 1010.     WAIVER OF CERTAIN COVENANTS.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(19),
901(2), 901(7), 1006, 1007, 1008 or 1009 for the benefit of the Holders of such
series if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series
shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the 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 redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.     ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. In case of any redemption at the election
of the Company of less than all the Securities of any series (including any
such redemption affecting only a single Security), the Company shall, at least
60 days prior to the Redemption Date fixed by the Company (unless a shorter
notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities to be redeemed. In
the case of any redemption of Securities 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 are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem





                                      -48-
<PAGE>   56
fair and appropriate and which may provide for the selection for redemption of
a portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects
only a single Security), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

         If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption. Securities which
have been converted during a selection of Securities to be redeemed shall be
treated by the Trustee as Outstanding for the purpose of such selection.

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

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

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

   
SECTION 1104.    NOTICE OF REDEMPTION.
    

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

         All notices of redemption shall state:

         (1)     the Redemption Date,

         (2)     the Redemption Price (including accrued interest, if any),

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

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

         (5)     the place or places where each such Security is to be
surrendered for payment of the Redemption Price,





                                      -49-
<PAGE>   57
         (6)     if applicable, the conversion price, that the date on which
the right to convert the principal of the Securities or the portions thereof to
be redeemed will terminate will be the Redemption Date and the place or places
where such Securities may be surrendered for conversion, and

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

         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 and shall be irrevocable.

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, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

         If any Security called for redemption is converted, any money
deposited with the Trustee or with a Paying Agent or so segregated and held in
trust for the redemption of such Security shall (subject to the right of any
Holder of such Security to receive interest as provided in the last paragraph
of Section 307) be paid to the Company on 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, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 301, installments of interest whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such
at the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307.

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

SECTION 1107.     SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or its 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 and of like tenor, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                 ARTICLE 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 any series except as otherwise specified as
contemplated by Section 301 for such Securities.

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

   
SECTION 1202.     SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.
    

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

SECTION 1203.     REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant
to Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the 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.

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.     COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302.     DEFEASANCE AND DISCHARGE.

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

SECTION 1303.     COVENANT DEFEASANCE.

         Upon the Company's exercise of its option (if any) to have this
Section applied to any Securities or any series of Securities, as the case may
be, (1) the Company shall be released from its obligations under Sections 1006
through 1009, inclusive, and any covenants provided pursuant to Section
301(19), 901(2) or 901(7) for the benefit of the Holders of such Securities and
(2) the occurrence of any event specified in Sections 501(4), Sections 1006
through 1009, inclusive, and any such covenants provided pursuant to Section
301(19), 901(2) or 901(7)) shall be deemed not to be or result in an Event of
Default, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason of
any reference in any such Section to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1304.     CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

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

         (1)     The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article 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 benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of
principal and interest in respect thereof in accordance with their terms will
provide, not later than one day before the due date of any payment, money in an
amount, or (C) a combination thereof, in each case sufficient, 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 any such other qualifying
trustee) to pay and discharge, the principal of and any premium and interest on
such Securities on the respective Stated Maturities, in accordance with the
terms of this Indenture and such Securities. As used herein, "U.S. Government
Obligation" means (x) any security which is (i) a direct obligation of the
United States of America for the payment of which the full faith and credit of
the United States of America is pledged or (ii) an obligation of a Person
controlled or supervised by and acting as an agency or instrumentality of the
United States of America the payment of which is unconditionally guaranteed as
a full faith and credit obligation by the United States of America, which, in
either case (i) or (ii), is not callable or redeemable at the option of the
issuer thereof, and (y) any depositary receipt issued by a bank (as defined in
Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S.
Government Obligation which is specified in Clause (x) above and held by such
bank for the account of the holder of such depositary receipt, or with respect
to any specific payment of principal of or interest on any U.S. Government
Obligation which is so specified and held, provided that (except as required by
law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depositary receipt from any amount received by
the custodian in respect of the U.S. Government Obligation or the specific
payment of principal or interest evidenced by such depositary receipt.

         (2)     In the event of an election to have Section 1302 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling or (B) since the date of this instrument, there has been a
change in the applicable Federal income tax law, in either case (A) or (B) to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Securities will not recognize gain or loss for Federal income tax
purposes as a result of the deposit, Defeasance and discharge to be effected
with respect to such Securities and will be subject to Federal income tax on
the same amount, in the same manner and at the same times as would be the case
if such deposit, Defeasance and discharge were not to occur.

         (3)     In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on
the same amount, in the same manner and at the same times as would be the case
if such deposit and Covenant Defeasance were not to occur.

         (4)     The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.





                                      -53-
<PAGE>   61
         (5)     No event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to such Securities or any other
Securities shall have occurred and be continuing at the time of such deposit
or, with regard to any such event specified in Sections 501(5) and (6), at any
time on or prior to the 90th day after the date of such deposit (it being
understood that this condition shall not be deemed satisfied until after such
90th day).

         (6)     Such Defeasance or Covenant Defeasance shall not cause the
Trustee to have a conflicting interest within the meaning of the Trust
Indenture Act (assuming all Securities are in default within the meaning of
such Act).

         (7)     Such Defeasance or Covenant Defeasance shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

         (8)     Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act unless such trust shall be registered
under such Act or exempt from registration thereunder.

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

SECTION 1305.     DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
                  TRUST; MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section and Section 1306, the Trustee and any such other trustee are
referred to collectively as the "Trustee") pursuant to Section 1304 in respect
of any Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the
Company acting as its own Paying Agent) as the Trustee may determine, to the
Holders of such Securities, of all sums due and to become due thereon in
respect of principal and any premium and interest, but money so held in trust
need not be segregated from other funds except to the extent required by law.

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

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304
with respect to any Securities which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect the Defeasance or Covenant
Defeasance, as the case may be, with respect to such Securities.

SECTION 1306.     REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or





                                      -54-
<PAGE>   62
otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to
apply all money held in trust pursuant to Section 1305 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any
such Security following such reinstatement of its obligations, the Company
shall be subrogated to the rights (if any) of the Holders of such Securities to
receive such payment from the money so held in trust.

                                ARTICLE FOURTEEN

                            CONVERSION OF SECURITIES

SECTION 1401.     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to the Securities
of any series which are convertible into shares of Common Stock of the Company,
and the issuance of such shares of Common Stock upon the conversion of such
Securities, except as otherwise specified as contemplated by Section 301 for
the Securities of such series.

SECTION 1402.     EXERCISE OF CONVERSION PRIVILEGE.

   
         In order to exercise a conversion privilege, the Holder of a Security
of a series with such a privilege shall surrender such Security to the Company
at the office or agency maintained for that purpose pursuant to Section 1002,
accompanied by a duly executed conversion notice to the Company substantially in
the form set forth in Section 206 stating that the Holder elects to convert such
Security or a specified portion thereof. Such notice shall also state, if
different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock
which shall be issuable on such conversion shall be issued. Securities
surrendered for conversion shall (if so required by the Company or the Trustee)
be duly endorsed by or accompanied by instruments of transfer in forms
satisfactory to the Company and the Trustee duly executed by the registered
Holder or its attorney duly authorized in writing; and Securities so surrendered
for conversion (in whole or in part) during the period from the close of
business on any Regular Record Date to the opening of business on the next
succeeding Interest Payment Date (excluding Securities or portions thereof
called for redemption during the period beginning at the close of business on a
Regular Record Date and ending at the opening of business on the first Business
Day after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day) shall also be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such Interest Payment Date on the principal amount of
such Security then being converted, and such interest shall be payable to such
registered Holder notwithstanding the conversion of such Security, subject to
the provisions of Section 307 relating to the payment of Defaulted Interest by
the Company. As promptly as practicable after the receipt of such notice and of
any payment required pursuant to a Board Resolution and, subject to Section 303,
set forth, or determined in the manner provided, in an Officers' Certificate, or
established in one or more indentures supplemental hereto setting forth the
terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the
Company shall issue and shall deliver, at the office or agency at which such
Security is surrendered, to such Holder or on its written order, a certificate
or certificates for the number of full shares of Common Stock issuable upon the
conversion of such Security (or specified portion thereof), in accordance with
the provisions of such Board Resolution, Officers' Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of
such Common Stock otherwise issuable upon such conversion. Such conversion shall
be deemed to have been effected immediately prior to the close of business on
the date on which such notice and such payment, if required, shall have been
received in proper order for conversion by the Company and such Security shall
have been surrendered as aforesaid (unless such Holder shall have so surrendered
such Security and shall have instructed the Company to effect the conversion on
a particular date
    





                                      -55-
<PAGE>   63
following such surrender and such Holder shall be entitled to convert such
Security on such date, in which case such conversion shall be deemed to be
effected immediately prior to the close of business on such date) and at such
time the rights of the Holder of such Security as such Security Holder shall
cease and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock of the Company shall be issuable upon
such conversion shall be deemed to have become the Holder or Holders of record
of the shares represented thereby. Except as set forth above and subject to the
final paragraph of Section 307, no payment or adjustment shall be made upon any
conversion on account of any interest accrued on the Securities (or any part
thereof) surrendered for conversion or on account of any dividends on the
Common Stock of the Company issued upon such conversion.

         In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to or on the order of the Holder thereof, at the expense of the
Company, a new Security or Securities of the same series, of authorized
denominations, in aggregate principal amount equal to the unconverted portion
of such Security.

SECTION 1403.     NO FRACTIONAL SHARES.

   
         No fractional share of Common Stock of the Company shall be issued upon
conversions of Securities of any series. If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Securities (or specified portions thereof
to the extent permitted hereby) so surrendered. If, except for the provisions of
this Section 1403, any Holder of a Security or Securities would be entitled to a
fractional share of Common Stock of the Company upon the conversion of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Common Stock is listed or admitted to
unlisted trading privileges on a national securities exchange or market, on the
basis of the last reported sale price regular way on such exchange or market on
the last trading day prior to the date of conversion upon which such a sale
shall have been effected, or (ii) if such Common Stock is not at the time so
listed or admitted to unlisted trading privileges on a national securities
exchange or market, on the basis of the average of the bid and asked prices of
such Common Stock in the over-the-counter market, on the last trading day prior
to the date of conversion, as reported by the National Quotation Bureau,
Incorporated or similar organization if the National Quotation Bureau,
Incorporated is no longer reporting such information, or if not so available,
the fair market price as determined by the Board of Directors. For purposes of
this Section, "trading day" shall mean each Monday, Tuesday, Wednesday, Thursday
and Friday other than any day on which the Common Stock is not traded on the
Nasdaq National Market, or if the Common Stock is not traded on the
Nasdaq National Market, on the principal exchange or market on which the
Common Stock is traded or quoted.
    

SECTION 1404.     ADJUSTMENT OF CONVERSION PRICE.

         The conversion price of Securities of any series that is convertible
into Common Stock of the Company shall be adjusted for any stock dividends,
stock splits, reclassifications, combinations or similar transactions in
accordance with the terms of the supplemental indenture or Board Resolutions
setting forth the terms of the Securities of such series.

         Whenever the conversion price is adjusted, the Company shall compute
the adjusted conversion price in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted conversion price and showing in reasonable detail
the facts upon which such adjustment is based, and such certificate shall
forthwith be filed at each office or agency maintained for the purpose of
conversion of Securities pursuant to Section 1002 and, if different, with the
Trustee. The Company shall forthwith cause a notice setting forth the adjusted
conversion price to be mailed, first class postage prepaid, to each Holder of





                                      -56-
<PAGE>   64
Securities of such series at its address appearing on the Security Register and
to any conversion agent other than the Trustee.

SECTION 1405.     NOTICE OF CERTAIN CORPORATE ACTIONS.

         In case:

         (1)     the Company shall declare a dividend (or any other
distribution) on its Common Stock payable otherwise than in cash out of its
retained earnings (other than a dividend for which approval of any shareholders
of the Company is required) that would require an adjustment pursuant to
Section 1404; or

         (2)     the Company shall authorize the granting to all or
substantially all of the holders of its Common Stock of rights, options or
warrants to subscribe for or purchase any shares of capital stock of any class
or of any other rights (other than any such grant for which approval of any
shareholders of the Company is required); or

         (3)     of any reclassification of the Common Stock of the Company
(other than a subdivision or combination of its outstanding shares of Common
Stock, or of any consolidation, merger or share exchange to which the Company
is a party and for which approval of any shareholders of the Company is
required), or of the sale of all or substantially all of the assets of the
Company; or

         (4)     of the voluntary or involuntary dissolution, liquidation or
winding up of the Company;

   
then the Company shall cause to be filed with the Trustee, and shall cause to
be mailed to all Holders at their last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in
Clause (1) or (2) above) prior to the applicable record date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for
the purpose of such dividend, distribution, rights, options or warrants, or, if
a record is not to be taken, the date as of which the holders of Common Stock
of record to be entitled to such dividend, distribution, rights, options or
warrants are to be determined, or (ii) the date on which such reclassification,
consolidation, merger, share exchange, sale, dissolution, liquidation or
winding up is expected to become effective, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, share exchange, sale,
dissolution, liquidation or winding up. If at any time the Trustee shall not be
the conversion agent, a copy of such notice shall also forthwith be filed by
the Company with the Trustee.
    

SECTION 1406.     RESERVATION OF SHARES OF 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
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock of the Company then issuable upon the conversion of all
outstanding Securities of any series that has conversion rights.

SECTION 1407.     PAYMENT OF CERTAIN TAXES UPON CONVERSION.

         Except as provided in the next sentence, the Company will pay any and
all taxes that may be payable in respect of the issue or delivery of shares of
its 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 its 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





                                      -57-
<PAGE>   65
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 1408.     NONASSESSABILITY.

         The Company covenants that all shares of its Common Stock which may be
issued upon conversion of Securities will upon issue in accordance with the
terms hereof be duly and validly issued and fully paid and nonassessable.

SECTION 1409.     PROVISION IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

         In case of any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets
of the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security of a series then Outstanding that is convertible into Common
Stock of the Company shall have the right thereafter (which right shall be the
exclusive conversion right thereafter available to said Holder), during the
period such Security shall be convertible, to convert such Security only into
the kind and amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, 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,
conveyance, sale, transfer or lease, assuming such holder of Common Stock of
the Company (i) is not a Person with which the Company consolidated or merged
with or into or which merged into or with the Company or to which such
conveyance, sale, transfer or lease was made, as the case may be (a
"Constituent Person"), or an Affiliate of a Constituent Person and (ii) 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,
conveyance, sale, transfer or lease (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer, or lease is not the same for each share of Common
Stock of the Company held immediately prior to such consolidation, merger,
conveyance, sale, transfer or lease by others than a Constituent Person or an
Affiliate thereof and in respect of which such rights of election shall not
have been exercised ("Non- electing Share"), then for the purpose of this
Section 1409 the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer or lease
by the holders of each Non-electing Share shall be deemed to be the kind and
amount so receivable per share by a plurality of the Non-electing Shares).
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 or in accordance with the terms of the supplemental indenture or Board
Resolutions setting forth the terms of such adjustments.  The above provisions
of this Section 1409 shall similarly apply to successive consolidations,
mergers, conveyances, sales, transfers or leases.  Notice of the execution of
such a supplemental indenture shall be given by the Company to the Holder of
each Security of a series that is convertible into Common Stock of the Company
as provided in Section 106 promptly upon such execution.

         Neither the Trustee nor any conversion agent, if any, shall be under
any responsibility to determine the correctness of any provisions contained in
any such supplemental indenture relating either to the kind or amount of shares
of stock or other securities or property or cash receivable by Holders of
Securities of a series convertible into Common Stock of the Company upon the
conversion of their Securities after any such consolidation, merger,
conveyance, transfer, sale or lease or to any such adjustment, but may accept
as conclusive evidence of the correctness





                                      -58-
<PAGE>   66
of any such provisions, and shall be protected in relying upon, an Opinion of
Counsel with respect thereto, which the Company shall cause to be furnished to
the Trustee upon request.

SECTION 1410.     DUTIES OF TRUSTEE REGARDING CONVERSION.

         Neither the Trustee nor any conversion agent shall at any time be
under any duty or responsibility to any Holder of Securities of any series that
is convertible into Common Stock of the Company to determine whether any facts
exist which may require any adjustment of the conversion price, or with respect
to the nature or extent of any such adjustment when made, or with respect to
the method employed, whether herein or in any supplemental indenture, any
resolutions of the Board of Directors or written instrument executed by one or
more officers of the Company provided to be employed in making the same.
Neither the Trustee nor any conversion agent shall be accountable with respect
to the validity or value (or the kind or amount) of any shares of Common Stock
of the Company, or of any securities or property, which may at any time be
issued or delivered upon the conversion of any Securities and neither the
Trustee nor any conversion agent makes any representation with respect thereto.
Subject to the provisions of Section 601, neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of its Common Stock or stock certificates or
other securities or property upon the surrender of any Security for the purpose
of conversion or to comply with any of the covenants of the Company contained
in this Article Fourteen or in the applicable supplemental indenture,
resolutions of the Board of Directors or written instrument executed by one or
more duly authorized officers of the Company.

SECTION 1411.     REPAYMENT OF CERTAIN FUNDS UPON CONVERSION.

         Any funds which at any time shall have been deposited by the Company
or on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article Twelve and funds deposited pursuant to Article
Thirteen hereof) and which shall not be required for such purposes because of
the conversion of such Securities as provided in this Article Fourteen shall
after such conversion be repaid to the Company by the Trustee upon the
Company's written request.

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

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed, and their respective corporate seals to be hereunto affixed
and attested, all as of the day and year first above written.

action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. The
Trustee shall promptly deliver to the Company copies of all such instrument or

acknowledgments of deeds, certifying that the individual signing such instrument

determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, vote, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities


                                       -9-

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

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

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

SECTION 105.    NOTICES, ETC., TO TRUSTEE AND COMPANY.

<PAGE>   18
         (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 (or by
facsimile transmissions ((213) 362-7357), provided that oral confirmation of
receipt shall have been received) to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust Department, 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

SECTION 106.    NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such

by such event, at its address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

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

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

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

SECTION 111.    BENEFITS OF INDENTURE.

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

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

SECTION 113.    LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert a Security at a particular conversion price shall not be a Business Day
at any Place of Payment, then (notwithstanding any other provision of this
Indenture or of the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) or, if applicable to a
particular series of Securities, conversion need not be made at such Place of
Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest
Payment Date or Redemption Date, at the Stated Maturity or on such last day for
conversion, as the case may be.

SECTION 114.    INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

         No recourse for the payment of the principal of or premium, if any, or
interest on any Security, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in this Indenture or in any supplemental indenture or in any
Security, or because of the creation of any indebtedness represented thereby,

director or subsidiary, as such, past, present or future, of the Company or of

addition, the Indenture provides that in case of certain consolidations or
mergers to which the Company is a party or the sale of substantially all of the

consent of the Holders of more than 50% in principal amount of the Securities at

provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company

Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of

Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

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

<PAGE>   29

case, the respective Depositaries for such Global Securities, the form of any
legend or legends which shall be borne by any such Global Security in addition
to or in lieu of that set forth in Section 204 and any circumstances in addition
to or in lieu of those set forth in Clause (2) of the last paragraph of Section
305 in which any such Global Security may be exchanged in whole or in part for
Securities registered, and any transfer of such Global Security in whole or in
part may be registered, in the name or names of Persons other than the
Depositary for such Global Security or a nominee thereof;

         (18) any addition to or change in the Events of Default which applies
to any Securities of the series and any change in the right of the Trustee or

         All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set
forth, or determined in the manner provided, in the Officers' Certificate
referred to above or in any such indenture supplemental hereto.

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

         The Securities shall be subordinated in right of payment to Senior Debt
as provided in Article Fifteen.

SECTION 302.    DENOMINATIONS.

         The Securities of each series shall be issuable only in registered form
without coupons and only in such denominations as shall be specified as
contemplated by Section 301. In the absence of any such specified denomination
with respect to the Securities of any series, the Securities of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303.    EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

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

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the 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.


                                      -22-
<PAGE>   30
         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. If the
form or terms of the Securities of the series have been established by or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, a copy of such Board Resolution, the Officers' Certificate setting
forth the terms of the series and an Opinion of Counsel, with such Opinion of
Counsel stating,

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

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

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

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

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

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

SECTION 304.    TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,


                                      -23-
<PAGE>   31
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

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

SECTION 305.    REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

         Upon surrender for registration of transfer of any Security of a series
at the office or agency of the 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 Securities
of the same series, of any authorized denominations and of like tenor and
aggregate principal amount.

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

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

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

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


                                      -24-
<PAGE>   32
         If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at the
opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103 and
ending at the close of business on the day of such mailing, or (B) to register
the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part.

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

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

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

         (3) Subject to Clause (2) above, any exchange of a Global Security for
other Securities may be made in whole or in part, and all Securities issued in
exchange for a Global Security or any portion thereof shall be registered in
such names as the Depositary for such Global Security shall direct.

         (4) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security, unless such Security is registered in the name of a Person
other than the Depositary for such Global Security or a nominee thereof.

SECTION 306.    MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

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

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


                                      -25-
<PAGE>   33
         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 issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

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

SECTION 307.    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

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

         (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series
and the date of the proposed payment, and at the same time the Company shall
deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
given to each Holder of Securities of such series in the manner set forth in
Section 106, not less than 10 days prior to such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor having been so mailed, such Defaulted Interest shall be paid to the
Persons in whose names the Securities of such series (or their respective
Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following Clause (2).

         (2) The Company may make payment of any Defaulted Interest on the
Securities of any series in any other lawful manner not inconsistent with the
requirements of any securities exchange on which 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.


                                      -26-
<PAGE>   34
         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

         Subject to the provisions of Section 1402, in the case of any Security
(or any part thereof) which is converted after any Regular Record Date and on or
prior to the next succeeding Interest Payment Date (other than any Security the
principal of (or premium, if any, on) which shall become due and payable,
whether at Stated Maturity or by declaration of acceleration prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name that Security (or any one or more
Predecessor Securities) is registered at the close of business on such Regular
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence or in Section 1402, in the case of any Security (or any part thereof)
which is converted, interest whose Stated Maturity is after the date of
conversion of such Security (or such part thereof) shall not be payable.

SECTION 308.    PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309.    CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The 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 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
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be disposed of as directed by a Company Order.

SECTION 310.    COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for

SECTION 401.    SATISFACTION AND DISCHARGE OF INDENTURE.

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

         (1)      either

                  (A) all Securities theretofore authenticated and delivered
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 306 and
         (ii) Securities for whose payment money 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 such Securities not theretofore delivered to the
         Trustee for cancellation

                             (i) have become due and payable, or

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

         and the Company, in the case of (i), (ii) or (iii) above, has deposited
         or caused to be deposited with the Trustee as trust funds in trust for
         the purpose money in an amount sufficient to pay and discharge the
         entire indebtedness on such Securities not theretofore delivered to the
         Trustee for cancellation, for principal and any premium and interest to
         the date of such deposit (in the case of Securities which have become
         due and payable) or to the Stated 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

Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture have been complied with.

obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

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 and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
Fifteen or 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):

whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such
default or breach for a period of 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) the entry by a court having jurisdiction in the premises of (A) a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or (B) a decree or order adjudging the
Company a bankrupt or insolvent, or approving as properly filed a petition
seeking reorganization, arrangement, adjustment or composition of or in respect
of the Company under any applicable Federal or State law, or appointing a

ordering the winding up or liquidation of its affairs, and the continuance of
any such decree or order for relief or any such other decree or order unstayed
and in effect for a period of 90 consecutive days; or

         (6) the commencement by the Company of a voluntary case or proceeding
under any applicable Federal or State bankruptcy, insolvency, reorganization or
other similar law or of any other case or proceeding to be


                                      -29-
<PAGE>   37
adjudicated a bankrupt or insolvent, or the consent by it to the entry of a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or
insolvency case or proceeding against it, or the filing by it of a petition or
answer or consent seeking reorganization or relief under any applicable Federal

appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or other similar official of the Company or of
any substantial part of its property, or the making by it of an assignment for
the benefit of creditors, or the admission by it in writing of its inability to
pay its debts generally as they become due, or the taking of corporate action by
the Company in furtherance of any such action; or

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

SECTION 502.    ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 501(5) or 501(6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount of all the Securities of that
series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) shall become
immediately due and payable. If an Event of Default specified in Section 501(5)
or 501 (6) with respect to Securities of any series at the time Outstanding
occurs, the principal amount of all the Securities of that series (or, if any
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified by the terms
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, 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 and its consequences if

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

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

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

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

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


                                      -30-

<PAGE>   38
         (2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513.

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

SECTION 503.    COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

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

SECTION 504.    TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

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

SECTION 506.  APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

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

         SECOND: Subject to Article Fifteen, to the payment of the amounts then
due and unpaid for principal of and any premium, if any, and interest on the
Securities in respect of which or for the benefit of which such money has been
collected, ratably, without preference or priority of any kind, according to the
amounts due and payable on such Securities for principal and any premium, if
any, and interest, respectively.

SECTION 507.  LIMITATION ON SUITS.

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

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

         (2)  the Holders of not less than 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 reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

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

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

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


                                      -32-
<PAGE>   40
any right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all of such Holders.

SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND 
              INTEREST AND TO CONVERT.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date), to convert
such Securities in accordance with Article Fourteen and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.

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

SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.  DELAY OR OMISSION NOT WAIVER.

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

SECTION 512.  CONTROL BY HOLDERS.

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


                                      -33-
<PAGE>   41
         (1)  such direction shall not be in conflict with any rule of law or
with this Indenture and the Trustee shall not have determined that the action so
directed would be unjustly prejudicial to Holders of Securities of that series,
or any other series, not taking part in such direction; and

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

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 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 any premium or interest on
any Security of such series, or

         (2)  in respect of a covenant or provision hereof which under Article
Nine cannot be modified or amended without the consent of the Holder of each
Outstanding Security of 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 impair any right consequent thereon.

SECTION 514.  UNDERTAKING FOR COSTS.

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

SECTION 515.  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 601.  CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602.  NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.

SECTION 603.  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

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

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

         (3)  whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (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 pursuant to this Indenture, unless such Holders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

         (6)  the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;
and

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

SECTION 604.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, 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. 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 605.  MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other agent.

         Subject to the limitations imposed by the Trust Indenture Act, nothing
in this Indenture shall prohibit the Trustee from becoming and acting as trustee
under other indentures under which other securities, or certificates of interest
of participation in other securities, of the Company are outstanding in the same
manner as if it were not Trustee hereunder.

SECTION 606.  MONEY HELD IN TRUST.

under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

SECTION 607.  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 the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision

                                      -36-
<PAGE>   44
of this Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

         (3)  to indemnify the 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.

SECTION 608.  CONFLICTING INTERESTS.

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

SECTION 609.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has (or if the
Trustee is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee with respect to the Securities of any
series shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

SECTION 610.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

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

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


                                      -37-
<PAGE>   45
         If at any time:

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

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

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

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

         If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, the
retiring Trustee may petition, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

         The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.

SECTION 611.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the 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 the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to


                                      -38-
<PAGE>   46
such successor Trustee all the rights, powers and trusts of the retiring Trustee
and shall duly assign, transfer and deliver to such successor Trustee all
property and money held by such retiring Trustee hereunder.

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

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

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

SECTION 612.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

SECTION 613.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

<PAGE>   47
SECTION 614.  APPOINTMENT OF AUTHENTICATING AGENT.

         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 original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having (or if the Authenticating Agent is a member of a bank holding
company system, its bank holding company has) a combined capital and surplus of
not less than $50,000,000 and subject to supervision or examination by Federal
or State authority. If such Authenticating Agent publishes reports of condition
at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

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

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section 612, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:


                                      -40-

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

         The rights of Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding

of principal of or interest on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or reduce the amount of the principal of an Original Issue
Discount Security or any other Security which would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 502, or
change any Place of Payment where, or the coin or currency in which, any
Security or any premium or interest thereon is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated
Maturity thereof (or, in the case of redemption, on or after the Redemption
Date), or modify the provisions of this Indenture with respect to the
subordination of such series of Securities in a manner adverse to the Holders of
Securities of such series, or

         (2)  reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for


                                      -44-
<PAGE>   52
any waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture, or

         (3)  modify any of the provisions of this Section, Section 513 or
Section 1008, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each Outstanding Security affected thereby; provided,
however, that this clause shall not be deemed to require the consent of any
Holder with respect to changes in the references to "the Trustee" and
concomitant changes in this Section and Section 1008, or the deletion of this
proviso, in accordance with the requirements of Sections 611 and 901(8), or

         (4)  if applicable, make any change that adversely affects the right to
convert any security as provided in Article Fourteen or pursuant to Section 301
(except as permitted by Section 901(9)) or decrease the conversion rate or
increase the conversion price of any such security.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

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

SECTION 903.  EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Sections 601 and 603) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES.

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

SECTION 905.  CONFORMITY WITH TRUST INDENTURE ACT.

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

SECTION 906.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

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


                                      -45-
<PAGE>   53
may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series.

SECTION 907.  SUBORDINATION UNIMPAIRED.

         No provision in any supplemental indenture which affects the superior
position of the holders of Senior Debt shall be effective against holders of
Senior Debt.

                                   ARTICLE TEN

                                    COVENANTS

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

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

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

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

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment 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.

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

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
or any premium or interest on any Securities of that series, deposit with a
Paying


                                      -46-
<PAGE>   54
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for a period
ending on the earlier of the date that is ten Business Days prior to the date
such money would escheat to the State or two years after such principal, premium
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; 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 a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in each Place of Payment, 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. STATEMENT BY OFFICERS AS TO DEFAULT.

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

SECTION 1005. 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 existence.



                                      -47-
<PAGE>   55
SECTION 1006. MAINTENANCE OF PROPERTIES.

         The Company will cause all properties used or useful in the conduct of
its business 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, and to the extent, 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 nothing in this
Section shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

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 the Company or upon the income,
profits or property of the Company, 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; 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 (i) whose amount, applicability or validity is being
contested in good faith by appropriate proceedings or (ii) if the failure to pay
or discharge would not have a material adverse effect on the assets, business,
operations, properties or condition (financial or otherwise) of the Company and
its Subsidiaries, taken as a whole.

SECTION 1008. WAIVER OF CERTAIN COVENANTS.

         Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(19),
901(2), 901(7), 1006 or 1007 for the benefit of the Holders of such series if
before the time for such compliance the Holders of at least 50% in principal
amount of the Outstanding Securities of such series shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the 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 redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the


                                      -48-
<PAGE>   56
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities 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 are to be redeemed
(unless all the Securities of such series and of a specified tenor are to be
redeemed or unless such redemption affects only a single Security), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of a portion of the principal amount of any Security of such series,
provided that the unredeemed portion of the principal amount of any Security
shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. If less than all the Securities of
such series and of a specified tenor are to be redeemed (unless such redemption
affects only a single Security), the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

         If any Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed (so
far as may be) to be the portion selected for redemption. Securities which have
been converted during a selection of Securities to be redeemed shall be treated
by the Trustee as Outstanding for the purpose of such selection.

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

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Security, whether such
Security is to be redeemed in whole or in part. In the case of any such
redemption in part, the unredeemed portion of the principal amount of the
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.

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

SECTION 1104. NOTICE OF REDEMPTION.

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

         All notices of redemption shall state:


                                      -49-
<PAGE>   57
         (1)  the Redemption Date,

         (2)  the Redemption Price (including accrued interest, if any),

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

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

         (5)  the place or places where each such Security is to be surrendered
for payment of the Redemption Price,

         (6)  if applicable, the conversion price, that the date on which the
right to convert the principal of the Securities or the portions thereof to be
redeemed will terminate will be the Redemption Date and the place or places
where such Securities may be surrendered for conversion, and

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

         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 and shall be irrevocable.

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, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

         If any Security called for redemption is converted, any money deposited
with the Trustee or with a Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to the right of any Holder of
such Security to receive interest as provided in the last paragraph of Section
307) be paid to the Company on 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, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

                                      -50-
<PAGE>   58
         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

SECTION 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or its 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 and of like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 ARTICLE 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 any series except as otherwise specified as
contemplated by Section 301 for such Securities.

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

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

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

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to


                                      -51-
<PAGE>   59
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the 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

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may elect, at its option at any time, to have Section 1302
or Section 1303 applied to any Securities or any series of Securities, as the
case may be, designated pursuant to Section 301 as being defeasible pursuant to
such Section 1302 or 1303, in accordance with any applicable requirements
provided pursuant to Section 301 and upon compliance with the conditions set
forth below in this Article. Any such election shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 301 for
such Securities.

SECTION 1302. DEFEASANCE AND DISCHARGE.

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

SECTION 1303. COVENANT DEFEASANCE.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1007, inclusive, and any covenants provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such Securities and (2) the
occurrence of any event specified in Sections 501(4) (with respect to any of
Sections 1006 through 1007, inclusive, and any such covenants provided pursuant
to Section 301(19), 901(2) or 901(7)), shall be deemed not to be or result in an
Event of Default, and (3) the provisions of Article Fifteen shall cease to be
effective, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall


                                      -52-
<PAGE>   60
have no liability in respect of any term, condition or limitation set forth in
any such specified Section (to the extent so specified in the case of Section
501(4)) or Article Fifteen, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in any
other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

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

         (1)  The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article 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 benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, 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 any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.

         (2)  In the event of an election to have Section 1302 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
has received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this instrument, there has been a change in
the applicable Federal income tax law, in either case (A) or (B) to the effect
that, and based thereon such opinion shall confirm that, the Holders of such
Securities will not recognize gain or loss for Federal income tax purposes as a
result of the deposit, Defeasance and discharge to be effected with respect to
such Securities and will be subject to Federal income tax on the same amount, in
the same manner and at the same times as would be the case if such deposit,
Defeasance and discharge were not to occur.

         (3)  In the event of an election to have Section 1303 apply to any
Securities or any series of Securities, as the case may be, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Securities will not recognize gain or loss for Federal income
tax purposes as a result of the deposit and Covenant Defeasance to be effected
with respect to such Securities and will be subject to Federal income tax on


                                      -53-
<PAGE>   61
the same amount, in the same manner and at the same times as would be the case
if such deposit and Covenant Defeasance were not to occur.

         (4)  The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

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

         (6)  Such Defeasance or Covenant Defeasance shall not cause the Trustee
to have a conflicting interest within the meaning of the Trust Indenture Act
(assuming all Securities are in default within the meaning of such Act).

         (7)  Such Defeasance or Covenant Defeasance shall not result in a 
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which it is bound.

         (8)  Such Defeasance or Covenant Defeasance shall not result in the
trust arising from such deposit constituting an investment company within the
meaning of the Investment Company Act unless such trust shall be registered
under such Act or exempt from registration thereunder.

         (9)  At the time of such deposit, (A) no default in the payment of any
principal of or premium or interest on any Senior Debt shall have occurred and
be continuing, (B) no event of default with respect to any Senior Debt shall
have resulted in such Senior Debt becoming, and continuing to be, due and
payable prior to the date on which it would otherwise have become due and
payable (unless payment of such Senior Debt has been made or duly provided for),
and (C) no other event of default with respect to any Senior Debt shall have
occurred and be continuing permitting (after notice or lapse of time or both)
the holders of such Senior Debt (or a trustee on behalf of such holders) to
declare such Senior Debt due and payable prior to the date on which it would
otherwise have become due and payable.

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

SECTION 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN 
              TRUST; MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
and any premium and interest, but money so held in trust need not be segregated
from other funds except to the extent required by law. Money and U.S. Government
Obligations so held in trust shall not be subject to the provisions of Article
Fifteen.


                                      -54-
<PAGE>   62
         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations held by it as provided in Section 1304 with
respect to any Securities which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to such Securities.

SECTION 1306. REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or interest on any such Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

                                ARTICLE FOURTEEN

                            CONVERSION OF SECURITIES

SECTION 1401. APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to the Securities of
any series which are convertible into shares of Common Stock of the Company, and
the issuance of such shares of Common Stock upon the conversion of such
Securities, except as otherwise specified as contemplated by Section 301 for the
Securities of such series.

SECTION 1402. EXERCISE OF CONVERSION PRIVILEGE.

         In order to exercise a conversion privilege, the Holder of a Security
of a series with such a privilege shall surrender such Security to the Company
at the office or agency maintained for that purpose pursuant to Section 1002,
accompanied by a duly executed conversion notice to the Company substantially in
the form set forth in Section 206 stating that the Holder elects to convert such
Security or a specified portion thereof. Such notice shall also state, if
different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock
which shall be issuable on such conversion shall be issued. Securities
surrendered for conversion shall (if so required by the Company or the Trustee)
be duly endorsed by or accompanied by instruments of transfer in forms
satisfactory to the Company and the Trustee duly executed by the registered
Holder or its attorney duly authorized in writing; and Securities so surrendered
for conversion (in whole or in part) during the period from the close of
business on any Regular Record Date to the opening of business on the next
succeeding Interest Payment Date (excluding Securities or portions thereof
called for redemption during the period


                                      -55-
<PAGE>   63
beginning at the close of business on a Regular Record Date and ending at the
opening of business on the first Business Day after the next succeeding Interest
Payment Date, or if such Interest Payment Date is not a Business Day, the second
such Business Day) shall also be accompanied by payment in funds acceptable to
the Company of an amount equal to the interest payable on such Interest Payment
Date on the principal amount of such Security then being converted, and such
interest shall be payable to such registered Holder notwithstanding the
conversion of such Security, subject to the provisions of Section 307 relating
to the payment of Defaulted Interest by the Company. As promptly as practicable
after the receipt of such notice and of any payment required pursuant to a Board
Resolution and, subject to Section 303, set forth, or determined in the manner
provided, in an Officers' Certificate, or established in one or more indentures
supplemental hereto setting forth the terms of such series of Security, and the
surrender of such Security in accordance with such reasonable regulations as the
Company may prescribe, the Company shall issue and shall deliver, at the office
or agency at which such Security is surrendered, to such Holder or on its
written order, a certificate or certificates for the number of full shares of
Common Stock issuable upon the conversion of such Security (or specified portion
thereof), in accordance with the provisions of such Board Resolution, Officers'
Certificate or supplemental indenture, and cash as provided therein in respect
of any fractional share of such Common Stock otherwise issuable upon such
conversion. Such conversion shall be deemed to have been effected immediately
prior to the close of business on the date on which such notice and such
payment, if required, shall have been received in proper order for conversion by
the Company and such Security shall have been surrendered as aforesaid (unless
such Holder shall have so surrendered such Security and shall have instructed
the Company to effect the conversion on a particular date following such
surrender and such Holder shall be entitled to convert such Security on such
date, in which case such conversion shall be deemed to be effected immediately
prior to the close of business on such date) and at such time the rights of the
Holder of such Security as such Security Holder shall cease and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock of the Company shall be issuable upon such conversion shall be
deemed to have become the Holder or Holders of record of the shares represented
thereby. Except as set forth above and subject to the final paragraph of Section
307, no payment or adjustment shall be made upon any conversion on account of
any interest accrued on the Securities (or any part thereof) surrendered for
conversion or on account of any dividends on the Common Stock of the Company
issued upon such conversion.

         In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to or on the order of the Holder thereof, at the expense of the Company,
a new Security or Securities of the same series, of authorized denominations, in
aggregate principal amount equal to the unconverted portion of such Security.

SECTION 1403. NO FRACTIONAL SHARES.

         No fractional share of Common Stock of the Company shall be issued upon
conversions of Securities of any series. If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Securities (or specified portions thereof
to the extent permitted hereby) so surrendered. If, except for the provisions of
this Section 1403, any Holder of a Security or Securities would be entitled to a
fractional share of Common Stock of the Company upon the conversion of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed, (i) if such Common Stock is listed or admitted to
unlisted trading privileges on a national securities exchange or market, on the
basis of the last reported sale price regular way on such exchange or market on
the last trading day prior to the date of conversion upon which such a sale
shall have been effected, or (ii) if such Common Stock is not at the time so
listed or admitted to unlisted trading privileges on a national securities
exchange or market, on the basis of the average of the bid and asked prices of
such Common Stock in the over-the-counter market, on the last trading day prior
to the date of conversion, as reported by the National Quotation Bureau,
Incorporated or similar


                                      -56-
<PAGE>   64
organization if the National Quotation Bureau, Incorporated is no longer
reporting such information, or if not so available, the fair market price as
determined by the Board of Directors. For purposes of this Section, "trading
day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday other than
any day on which the Common Stock is not traded on the Nasdaq National Market,
or if the Common Stock is not traded on the Nasdaq National Market, on the
principal exchange or market on which the Common Stock is traded or quoted.

SECTION 1404. ADJUSTMENT OF CONVERSION PRICE.

         The conversion price of Securities of any series that is convertible
into Common Stock of the Company shall be adjusted for any stock dividends,
stock splits, reclassifications, combinations or similar transactions in
accordance with the terms of the supplemental indenture or Board Resolutions
setting forth the terms of the Securities of such series.

         Whenever the conversion price is adjusted, the Company shall compute
the adjusted conversion price in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted conversion price and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of conversion of
Securities pursuant to Section 1002 and, if different, with the Trustee. The
Company shall forthwith cause a notice setting forth the adjusted conversion
price to be mailed, first class postage prepaid, to each Holder of Securities of
such series at its address appearing on the Security Register and to any
conversion agent other than the Trustee.

SECTION 1405. NOTICE OF CERTAIN CORPORATE ACTIONS.

         In case:

         (1)  the Company shall declare a dividend (or any other distribution) 
on its Common Stock payable otherwise than in cash out of its retained earnings
(other than a dividend for which approval of any shareholders of the Company is
required) that would require an adjustment pursuant to Section 1404; or

         (2)  the Company shall authorize the granting to all or substantially
all of the holders of its Common Stock of rights, options or warrants to
subscribe for or purchase any shares of capital stock of any class or of any
other rights (other than any such grant for which approval of any shareholders
of the Company is required); or

         (3)  of any reclassification of the Common Stock of the Company (other
than a subdivision or combination of its outstanding shares of Common Stock, or
of any consolidation, merger or share exchange to which the Company is a party
and for which approval of any shareholders of the Company is required), or of
the sale of all or substantially all of the assets of the Company; or

         (4)  of the voluntary or involuntary dissolution, liquidation or 
winding up of the Company;

then the Company shall cause to be filed with the Trustee, and shall cause to be
mailed to all Holders at their last addresses as they shall appear in the
Security Register, at least 20 days (or 10 days in any case specified in Clause
(1) or (2) above) prior to the applicable record date hereinafter specified, a
notice stating (i) the date on which a record is to be taken for the purpose of
such dividend, distribution, rights, options or warrants, or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, or (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is


                                      -57-
<PAGE>   65
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, share exchange, sale,
dissolution, liquidation or winding up. If at any time the Trustee shall not be
the conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

SECTION 1406. RESERVATION OF SHARES OF 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
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock of the Company then issuable upon the conversion of all outstanding
Securities of any series that has conversion rights.

SECTION 1407. PAYMENT OF CERTAIN TAXES UPON CONVERSION.

         Except as provided in the next sentence, the Company will pay any and
all taxes that may be payable in respect of the issue or delivery of shares of
its 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 its 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 1408. NONASSESSABILITY.

         The Company covenants that all shares of its Common Stock which may be
issued upon conversion of Securities will upon issue in accordance with the
terms hereof be duly and validly issued and fully paid and nonassessable.

SECTION 1409. PROVISION IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

         In case of any consolidation or merger of the Company with or into any
other Person, any merger of another Person with or into the Company (other than
a merger which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company) or any
conveyance, sale, transfer or lease of all or substantially all of the assets of
the Company, the Person formed by such consolidation or resulting from such
merger or which acquires such assets, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture providing that the Holder of
each Security of a series then Outstanding that is convertible into Common Stock
of the Company shall have the right thereafter (which right shall be the
exclusive conversion right thereafter available to said Holder), during the
period such Security shall be convertible, to convert such Security only into
the kind and amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance, 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, conveyance,
sale, transfer or lease, assuming such holder of Common Stock of the Company (i)
is not a Person with which the Company consolidated or merged with or into or
which merged into or with the Company or to which such conveyance, sale,
transfer or lease was made, as the case may be (a "Constituent Person"), or an
Affiliate of a Constituent Person and (ii) 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, conveyance, sale, transfer
or lease (provided that if the kind or amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, sale, transfer,
or lease is not the same for each share of Common Stock of the Company held
immediately prior to such consolidation,


                                      -58-
<PAGE>   66
merger, conveyance, sale, transfer or lease by others than a Constituent Person
or an Affiliate thereof and in respect of which such rights of election shall
not have been exercised ("Non-electing Share"), then for the purpose of this
Section 1409 the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance, sale, transfer or lease
by the holders of each Non-electing Share shall be deemed to be the kind and
amount so receivable per share by a plurality of the Non-electing Shares). 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 or in accordance with the terms of the supplemental indenture or Board
Resolutions setting forth the terms of such adjustments. The above provisions of
this Section 1409 shall similarly apply to successive consolidations, mergers,
conveyances, sales, transfers or leases. Notice of the execution of such a
supplemental indenture shall be given by the Company to the Holder of each
Security of a series that is convertible into Common Stock of the Company as
provided in Section 106 promptly upon such execution.

         Neither the Trustee nor any conversion agent, if any, shall be under
any responsibility to determine the correctness of any provisions contained in
any such supplemental indenture relating either to the kind or amount of shares
of stock or other securities or property or cash receivable by Holders of
Securities of a series convertible into Common Stock of the Company upon the
conversion of their Securities after any such consolidation, merger, conveyance,
transfer, sale or lease or to any such adjustment, but may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in
relying upon, an Opinion of Counsel with respect thereto, which the Company
shall cause to be furnished to the Trustee upon request.

SECTION 1410. DUTIES OF TRUSTEE REGARDING CONVERSION.

         Neither the Trustee nor any conversion agent shall at any time be under
any duty or responsibility to any Holder of Securities of any series that is
convertible into Common Stock of the Company to determine whether any facts
exist which may require any adjustment of the conversion price, or with respect
to the nature or extent of any such adjustment when made, or with respect to the
method employed, whether herein or in any supplemental indenture, any
resolutions of the Board of Directors or written instrument executed by one or
more officers of the Company provided to be employed in making the same. Neither
the Trustee nor any conversion agent shall be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock of the
Company, or of any securities or property, which may at any time be issued or
delivered upon the conversion of any Securities and neither the Trustee nor any
conversion agent makes any representation with respect thereto. Subject to the
provisions of Section 601, neither the Trustee nor any conversion agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of its Common Stock or stock certificates or other securities or property
upon the surrender of any Security for the purpose of conversion or to comply
with any of the covenants of the Company contained in this Article Fourteen or
in the applicable supplemental indenture, resolutions of the Board of Directors
or written instrument executed by one or more duly authorized officers of the
Company.

SECTION 1411. REPAYMENT OF CERTAIN FUNDS UPON CONVERSION.

         Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including, but not limited to, funds deposited for the sinking
fund referred to in Article Twelve hereof and funds deposited pursuant to
Article Thirteen hereof) and which shall not be required for such purposes
because of the conversion of such Securities as provided in this Article
Fourteen shall after such conversion be repaid to the Company by the Trustee
upon the Company's written request.

                           SUBORDINATION OF SECURITIES

SECTION 1501. SECURITIES SUBORDINATE TO SENIOR DEBT.

         Except as otherwise provided in a supplemental indenture or pursuant to
Section 301, the Company covenants and agrees, and each Holder of a Security, by
its 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 Securities and the payment of the principal of and any
premium and interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Debt.

SECTION 1502. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

         In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization, debt restructuring 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 the holders of Senior Debt shall be entitled to
receive payment in full of all amounts due or to become due on or in respect of
all Senior Debt, or provision shall be made for such payment, in money or
money's worth, before the Holders of the Securities are entitled to receive any
payment on account of principal of or any premium or interest on the Securities
or on the account of the purchase, redemption or other acquisition of
Securities, and to that end the holders of Senior Debt or their representative
or representatives or the trustee or trustees under any indenture under which
any instruments evidencing any of such Senior Debt may have been issued shall be
entitled to receive, for application to the payment thereof, any payment or
distribution of any kind or character, whether in cash, property or securities,
which may be payable or deliverable in respect of the Securities in any such
case, proceeding, dissolution, liquidation or other winding up or event, to the
extent necessary to pay all Senior Debt in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt.

         In the event that, notwithstanding the foregoing provisions of this
Section, 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, before all Senior Debt is paid in full
or payment thereof provided for, in money or money's worth then, and in such
event such payment or distribution shall be paid over or delivered forthwith to
the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee,
agent or other Person making payment or distribution of assets of the Company
for application to the payment of all Senior Debt remaining unpaid, to the
extent necessary to pay all Senior Debt in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt.

         For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock 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 which are subordinated
in right of payment to all Senior Debt which may at the time be outstanding to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article. The consolidation of the
Company with, or the merger of the Company into, another Person or the
liquidation or dissolution of the Company following the conveyance or transfer
of its properties and assets substantially as an entirety to another Person upon
the terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation, reorganization, assignment for the benefit

purposes of this Section if the Person

formed by such consolidation or into which the Company is merged or which
acquires by conveyance or transfer such properties and assets substantially 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.

SECTION 1503. PRIOR PAYMENT TO SENIOR DEBT UPON ACCELERATION OF SECURITIES.

         In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of the Senior Debt
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full of all amounts due or to become due on or in
respect of all Senior Debt, or provision shall be made for such payment, in
money or money's worth, before the Holders of the Securities are entitled to
receive any payment by the Company on account of the principal of or any premium
or interest on the Securities or on account of the purchase, redemption or other
acquisition of Securities; provided, however, that nothing in this Section shall
prevent the satisfaction of any sinking fund payment in accordance with Article
Twelve by delivering and crediting pursuant to Section 1202 Securities which
have been acquired (upon redemption or otherwise) prior to such declaration of
acceleration or which have been converted pursuant to Article Fourteen. If the
payment of Securities is accelerated because of an Event of Default, the Company
shall promptly notify holders of Senior Debt of the acceleration.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 1502 would be applicable.

SECTION 1504. NO PAYMENT IN CERTAIN CIRCUMSTANCES.

         The Company may not make any payment of principal of, or premium, if
any, or interest on the Securities on or account of the purchase, redemption or
other acquisition of Securities, if:

              (i)  a default in the payment of principal, premium, if any, or
         interest (including a default under any redemption or repurchase
         obligation) or other amounts with respect to any Senior Debt occurs and
         is continuing (or, in the case of Senior Debt for which there is a
         period of grace, in the event of such a default that continues beyond
         the period of grace, if any, specified in the instrument or lease
         evidencing such Senior Debt) unless and until such default shall have
         been cured or waived or shall have ceased to exist; or

              (ii) a default, other than a payment default, on any Designated
         Senior Debt occurs and is continuing that then permits holders of such
         Designated Senior Debt to accelerate its maturity and the Trustee
         receives a notice of the default (a "Payment Blockage Notice") from the
         Company, a holder such Designated Senior Debt or a Representative of
         such Designated Senior Debt.

; provided, however, that nothing in this Section shall prevent the satisfaction
of any sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202 Securities which have been acquired (upon
redemption or otherwise) prior to such declaration of acceleration or which have
been converted pursuant to Article Fourteen.


                                      -61-
<PAGE>   69
         If the Trustee receives any Payment Blockage Notice pursuant to clause
(ii) above, no subsequent Payment Blockage Notice shall be effective for
purposes of this Section unless and until (A) at least 365 days shall have
elapsed since the initial effectiveness of the immediately prior Payment
Blockage Notice, and (B) all scheduled payments of principal, premium, if any,
and interest on the Securities that have come due have been paid in full in
cash. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice.

         The Company may and shall resume payments on and distributions in
respect of the Securities and may purchase, redeem or otherwise acquire
Securities, upon the earlier of:

         (1)  the date upon which the default is cured or waived or ceases to
exist, or

         (2)  in the case of a default referred to in clause (ii) above, 179 
days pass after the Payment Blockage is received,

 unless this Article Fifteen otherwise prohibits the payment or distribution at
the time of such payment or distribution (including, without limitation, in the
case of a default referred to in clause (ii) above, as a result of a payment
default with respect to the applicable Senior Debt as a consequence of the
acceleration of the maturity thereof or otherwise).

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such payment, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 1502 would be applicable.


SECTION 1505. PAYMENT PERMITTED IF NO DEFAULT.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, debt restructuring, assignment for the benefit of creditors or other
marshaling of assets and liabilities of the Company referred to in Section 1502
or under the conditions described in Section 1503 or 1504, from making payments
at any time of principal of and any premium or interest on the Securities or on
the account of the purchase, redemption or other acquisition of Securities, or
(b) the application by the Trustee of any money deposited with it hereunder to
the payment of or on account of the principal of and any premium or interest on
the Securities or on the account of the purchase, redemption or other
acquisition of Securities, or the retention of such payment by the Holders, if,
at the time of such application by the Trustee, it did not have knowledge that
such payment would have been prohibited by the provisions of this Article.

SECTION 1506. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

         Subject to the payment in full of all Senior Debt, the Holders of the
Securities shall be subrogated to the rights of the holders of such Senior Debt
to receive payments and distributions of cash, property and securities
applicable to the Senior Debt until the principal of and any premium 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 Debt 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


                                      -62-
<PAGE>   70
Article, and no payments over pursuant to the provisions of this Article to the
holders of Senior Debt by Holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Debt and the
Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Debt.

SECTION 1507. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Debt 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 Debt 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 of the holders of Senior Debt, 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 any premium 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 Debt;
or (c) prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

SECTION 1508. TRUSTEE TO EFFECTUATE SUBORDINATION.

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

SECTION 1509. NO WAIVER OF SUBORDINATION PROVISIONS.

         No right of any present or future holder of any Senior Debt 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 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 Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior Debt, 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 Debt, or otherwise
amend or supplement in any manner Senior Debt or any instrument evidencing the
same or any agreement under which Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise dispose of any property pledged, mortgaged or
otherwise securing Senior Debt; (iii) release any Person liable in any manner
for the collection of Senior Debt; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

<PAGE>   71
SECTION 1510. NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any 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 Debt or from any trustee or other Representative
therefor; and, prior to the receipt of any such written notice, the Trustee,
subject to the provisions of Section 601, 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 two 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 any premium 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 two Business Days prior to such date.

         Subject to the provisions of Section 601, 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 Debt (or a trustee or other Representative
therefor) to establish that such notice has been given by a holder of Senior
Debt (or a trustee or other Representative 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 Debt to participate in any
payment or distribution pursuant to this Article, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Debt held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

SECTION 1511. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 601, 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 such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Debt 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 1512. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

         The Trustee, in its capacity as trustee under this Indenture, shall not
be deemed to owe any fiduciary duty to the holders of Senior Debt and shall not
be liable to any such holders if it shall in good faith mistakenly pay over or
distribute to Holders of Securities or to the Company or to any other Person
cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article or otherwise.


                                      -64-
<PAGE>   72
SECTION 1513. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION OF 
              TRUSTEE'S RIGHTS.

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

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

SECTION 1514. ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1512 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.

SECTION 1515. CERTAIN CONVERSIONS DEEMED PAYMENT.

         For the purposes of this Article only, (1) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article
Fourteen shall not be deemed to constitute a payment or distribution on account
of the principal of or any premium or interest on Securities or on account of
the purchase, redemption or other acquisition of Securities, and (2) the
payment, issuance or delivery of cash, property or securities (other than junior
securities and cash paid for fractional shares) upon conversion of a Security
shall be deemed to constitute payment on account of the principal of such
Security. For the purposes of this Section, the term "junior securities" means
(a) shares of any stock of any class of the Company and (b) securities of the
Company which are subordinated in right of payment to all Senior Debt which may
be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article.

SECTION 1516. OBLIGATIONS OF COMPANY AND RIGHT TO CONVERT UNCONDITIONAL.

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

         Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among the Company, its
creditors other than holders of Senior Debt and the Holders of the Securities,
the right, which is absolute and unconditional, of the Holder of any Security to
convert such Security in accordance with Article Fourteen (if applicable).
