                                DEBT SECURITIES
                          CONVERTIBLE DEBT SECURITIES

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

         Legg Mason, Inc. (the "Company") may offer from time to time, together
or separately, notes, debentures or other evidences of indebtedness ("Debt
Securities") in one or more series, which may be convertible ("Convertible Debt
Securities") into shares of the Company's Common Stock, par value $.10 per
share (the "Common Stock").  Debt Securities, including any Convertible Debt
Securities, may be issuable in registered form without coupons or in bearer
form with or without coupons attached.  The Company will offer Debt Securities
to the public on terms determined by market conditions.  Debt Securities may be
sold for U.S. dollars, foreign denominated currency or currency units;
principal of and any interest on Debt Securities may likewise be payable in
U.S. dollars, foreign denominated currency or currency units -- in each case,
as the Company specifically designates.  The Debt Securities, including any
Convertible Debt Securities, and the Common Stock underlying any such
Convertible Debt Securities are hereinafter collectively referred to as the
"Securities."

         The accompanying Prospectus Supplement will set forth the specific
terms of the Debt Securities, including the ranking as senior or subordinated
Debt Securities, the specific designation, aggregate principal amount, purchase
price, maturity, redemption terms, interest rate (or manner of calculation
thereof), time of payment of interest (if any), terms for any conversion
(including the terms relating to the adjustment thereof), listing (if any) on a
securities exchange and any other specific terms of the Debt Securities.  The
accompanying Prospectus Supplement will also set forth the name of and
compensation to each dealer, underwriter or agent (if any) involved in the sale
of the Debt Securities being offered and the managing underwriters with respect
to each series sold to or through underwriters.  Such underwriters (and any
representative thereof), dealers or agents may include Legg Mason Wood Walker,
Incorporated ("Legg Mason Wood Walker"), a wholly owned subsidiary of the
Company.

         The Securities may be sold directly, through agents, underwriters or
dealers as designated from time to time, or through a combination of such
methods.  See "Plan of Distribution."  If agents of the Company or any dealers
or underwriters are involved in the sale of the Securities in respect of which
this Prospectus is being delivered, the names of such agents, dealers or
underwriters and any applicable commissions or discounts will be set forth in
or may be calculated from the Prospectus Supplement with respect to such
Securities.  The net proceeds to the Company from such sale also will be set
forth in the applicable Prospectus Supplement.

         Following the initial distribution of a series of Securities, Legg
Mason Wood Walker may offer and sell previously issued Debt Securities in the
course of its business as a broker-dealer.  Legg Mason Wood Walker may act as
principal or agent in such transactions.  This Prospectus and the accompanying
Prospectus Supplement may be used by Legg Mason Wood Walker in connection with
such transactions.  Such sales, if any, will be made at varying prices related
to prevailing market prices at the time of sale.

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

This Prospectus may not be used to consummate sales of securities unless
accompanied by a Prospectus Supplement.

           THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY

                                USE OF PROCEEDS

         The Company intends to use the net proceeds from the sale of
Securities offered hereby for general corporate purposes, which may include the
continued expansion and diversification, both by internal growth and by
acquisition, primarily of its securities brokerage and investment advisory
businesses; repayment of any outstanding indebtedness of the Company or its
subsidiaries; or for such other uses as may be set forth in a Prospectus
Supplement.   Pending any of the foregoing applications, the net proceeds may
be invested temporarily in short-term, interest bearing securities.


                         DESCRIPTION OF DEBT SECURITIES

         The following description sets forth certain general terms and
provisions of the Debt Securities to which any Prospectus Supplement may
relate.  The particular terms of the Debt Securities offered by any Prospectus
Supplement and the extent, if any, to which such general provisions may not
apply to the Debt Securities so offered will be described in the Prospectus
Supplement relating to such Debt Securities.

         The Debt Securities will constitute either senior debt (the "Senior
Debt Securities") or subordinated debt (the "Subordinated Debt Securities") of
the Company.  The Senior Debt Securities will be issued under an Indenture (the
"Senior Indenture"), to be entered into between the Company and the trustee
named in the Senior Indenture.  The Subordinated Debt Securities will be issued
under a separate Indenture (the "Subordinated Indenture"), to be entered into
between the Company and the trustee named in the Subordinated Indenture.  The
Senior Indenture and the Subordinated Indenture are sometimes referred to
collectively as the "Indentures." Copies of the forms of the Senior Indenture
and the Subordinated Indenture have been filed as exhibits to the Registration
Statement.  The trustees under the Senior Indenture and under the Subordinated
Indenture are referred to herein as the "Trustees."

         The following summaries of certain provisions of the Senior Debt
Securities, the Subordinated Debt Securities and the Indentures do not purport
to be complete and are subject to, and qualified in their entirety by reference
to, all the provisions of the Indenture applicable to a particular series of
Debt Securities, including the definitions therein of certain terms.  Wherever
particular Sections, Articles or defined terms of the Indentures are referred
to herein or in a Prospectus Supplement, it is intended that such Sections,
Articles or defined terms shall be incorporated by reference herein or therein,
as the case may be.  Section and Article references used herein are references
to the applicable Indenture.  Except as otherwise indicated, the terms of the
Senior Indenture and the Subordinated Indenture are identical. Capitalized
terms not otherwise defined herein shall have the meanings given to them in the
applicable Indenture.  As used in the discussion under the caption "Description
of Debt Securities," the term "Company" means Legg Mason, Inc.

GENERAL

         The Indentures do not limit the aggregate principal amount of Debt
Securities which may be issued thereunder, and each Indenture provides that
Debt Securities may be issued thereunder from time to time in one or more
series up to the aggregate amount from time to time authorized by the Company
for each series. (Section 3.1) Unless otherwise specified in the Prospectus
Supplement, the Senior Debt Securities when issued will be unsecured and
unsubordinated obligations of the Company and will rank equally and ratably
with all other unsecured and unsubordinated indebtedness of the Company.  The
Subordinated Debt Securities when issued will be unsecured obligations of the
Company, subordinated in right of payment to the prior payment in full of all
Senior Debt (as defined in the Subordinated Indenture) of the Company as
described in the applicable Prospectus Supplement. (Section 15.1 of the
Subordinated Indenture) Substantially all of the assets of the Company are
owned by its subsidiaries.  Therefore, the Company's rights and the rights of
its creditors, including holders of Debt Securities, to participate in the
distribution of the assets of any subsidiary upon such





                                      -4-
<PAGE>   8
subsidiary's liquidation or recapitalization, or otherwise, will be subject to
the prior claims of such subsidiary's creditors, except to the extent that the
Company may itself be a creditor with recognized claims against the subsidiary.
In addition, dividends, loans and advances from certain of the Company's
subsidiaries, including Legg Mason Wood Walker, to the Company are restricted
by net capital requirements under the Exchange Act and under rules of certain
exchanges and various domestic and foreign regulatory bodies.

         Reference is made to the Prospectus Supplement relating to the
particular series of Debt Securities offered thereby for a description of the
following terms or additional provisions of the Debt Securities: (1) the title
of the Debt Securities; (2) whether the Debt Securities are Senior Debt

         Debt Securities may be issued as Original Issue Discount Securities.
An Original Issue Discount Security is a Debt Security, including any
Zero-Coupon Security, which is issued at a price lower than the amount payable
upon the Stated Maturity thereof and which provides that upon redemption or
acceleration of the maturity, an amount less than the amount payable upon the
Stated Maturity, determined in accordance with the terms of such Debt Security,
shall become due and payable. (Sections 3.1 and 5.2) Certain special United
States federal income tax considerations applicable to Debt Securities sold at
an original issue discount will be described in the Prospectus Supplement
relating thereto. In addition, certain special United States federal income tax
or other considerations applicable to any Debt Securities which are denominated
in a currency or currency unit other than United States dollars may be

         Under the Indentures, the Company will have the ability, in addition
to the ability to issue Debt Securities with terms different from those of Debt
Securities previously issued, without the consent of the holders, to reopen a
previous issue of a series of Debt Securities and issue additional Debt
Securities of such series (unless such reopening was restricted when such
series was created), in an aggregate principal amount determined by the
Company.  (Section 3.1)

FORM, EXCHANGE, REGISTRATION AND TRANSFER

         Debt Securities of a series may be issuable in definitive form solely
as Registered Securities, solely as Bearer Securities or as both Registered
Securities and Bearer Securities. (Section 3.1) Unless otherwise indicated in
an applicable Prospectus Supplement, Bearer Securities will have interest
coupons attached. (Section 2.1) The Indentures also provide that Debt
Securities of a series may be issuable in temporary or permanent global form
and may be issued as Book-Entry Securities that will be deposited with, or on
behalf of, The Depository Trust Company (the "Depository") or another
depository named by the Company and identified in a Prospectus Supplement with
respect to such series.  See "Global and Book-Entry Debt Securities."

         In connection with its original issuance, no Bearer Security
(including a Debt Security exchangeable for a Bearer Security or a Debt
Security in global form that is either a Bearer Security or exchangeable for
Bearer Securities) shall be mailed or otherwise delivered to any location in
the United States (as defined under "Limitations on Issuance of Bearer
Securities") and a Bearer Security may be delivered in connection with its
original issuance only if the Person entitled to receive such Bearer Security
furnishes written certification of the beneficial ownership of the Bearer
Security as required by Treasury Regulation Section 1.163-5(c)(2)(i)(D)(3) (or
any comparable successor provisions).  In the case of a Bearer Security in
permanent global form, such certification must be given in connection with
notation of a beneficial owner's interest therein in connection with the
original issuance of such Debt Security.  See "Global and Book-Entry Debt
Securities" and "Limitations on Issuance of Bearer Securities."

         Registered Securities of any series will be exchangeable for other
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor.  In addition, if Debt Securities
of any series are issuable as both Registered Securities and Bearer Securities,
at the option of the Holder upon request confirmed in writing, and subject to
the terms of the applicable Indenture, Bearer Securities (with all unmatured
coupons, except as provided below, and all matured coupons in default) of such
series will be exchangeable into Registered Securities of the same series of
any authorized denominations and of a like aggregate principal amount and
tenor.  Bearer Securities surrendered in exchange for Registered Securities
between a Regular Record Date or a Special Record Date and the relevant date
for payment of interest shall be surrendered without the coupon relating to
such date for payment of interest and interest accrued as of such date will not
be payable in respect of the Registered Security issued in exchange for such
Bearer Security, but will be payable only to the Holder of such coupon when due
in accordance with the terms of the applicable Indenture.  Registered
Securities will not be issued in exchange for Bearer Securities (Section 3.5).
Each Bearer Security, and any coupon attached thereto, other than a temporary
global Bearer Security will bear the following legend: "Any United States
person who holds this obligation will be subject to limitations under the
United States income tax laws, including the limitations provided in Sections
165(j) and 1287(a) of the United States Internal Revenue Code."  A Book-Entry
Security may not be registered for transfer or exchange (other than as a whole
by the Depository to a nominee or by such nominee to such Depository) unless
the Depository or such nominee notifies the Company that it is unwilling or
unable to continue as Depository or the Depository ceases to be qualified as
required by the applicable Indenture or the Company instructs the Trustee in
accordance with the applicable Indenture that such Book-Entry Securities shall
be so registrable and exchangeable or there shall have occurred and be
continuing an Event of Default or an event which after notice or lapse of time
would be an Event of Default with respect to the Debt Securities evidenced by
such Book-Entry Securities or there shall exist such other circumstances if
any, as may be specified in the applicable Prospectus Supplement.





                                      -6-
<PAGE>   10
         Debt Securities may be presented for exchange as provided above, and
Registered Securities may be presented or surrendered for registration of
transfer or for exchange (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 with respect to any
series of Debt Securities and referred to in an applicable Prospectus
Supplement, without service charge and upon payment of any taxes and other
governmental charges as described in the applicable Indenture.  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.  If a Prospectus Supplement refers
to any transfer agents (in addition to the Security Registrar) initially
designated by the Company with respect to any series of Debt Securities, the
Company may at any time rescind the designation of any such transfer agent or
approve a change in the location through which any such transfer agent acts,
except that, if Debt Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a transfer agent in each
Place of Payment for such series and, if Debt Securities of a series are
issuable as Bearer Securities, the Company will be required to maintain (in
addition to the Security Registrar) a transfer agent in a Place of Payment for
such series located outside the United States. The Company may at any time
designate additional transfer agents with respect to any series of Debt
Securities. (Section 10.2)

         In the event of any redemption in part, the Company shall not be
required to (i) issue, register the transfer of or exchange Debt Securities of
any series during a period beginning at the opening of business 15 days before
any selection of Debt Securities of that series to be redeemed and ending at
the close of business on (A) if Debt Securities of the series are issuable only
as Registered Securities, the day of mailing of the relevant notice of
redemption and (B) if Debt Securities of the series are issuable as Bearer
Securities, the day of the first publication of the relevant notice of
redemption or, if Debt Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption; (ii) register the transfer of or exchange any Registered Security
being redeemed in part, except the unredeemed portion of any Registered
Security being redeemed in part; or (iii) exchange any Bearer Security so
selected for redemption, except that such Bearer Security may be exchanged for
a Registered Security of that series and like tenor, provided that such
Registered Security shall be simultaneously surrendered for redemption.
(Section 3.5)

PAYMENT AND PAYING AGENTS

         Unless otherwise indicated in an applicable Prospectus Supplement,
payment of the principal of (and premium, if any) and interest on Bearer
Securities will be made, subject to any applicable laws and regulations, at the
offices of such Paying Agents outside the United States as the Company may
designate from time to time, at the option of the Holder, by check or by
transfer to an account maintained by the payee with a bank located outside the
United States.  Unless otherwise indicated in an applicable Prospectus
Supplement, payment of interest on Bearer Securities on any Interest Payment
Date will be made only against surrender to the Paying Agent of such coupon
relating to such Interest Payment Date. (Section 10.1)  No payment with respect
to any Bearer Security will be made at any office or agency of the Company in
the United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States.
Notwithstanding the foregoing, payments of the principal of (and premium, if
any) and interest on Bearer Securities denominated and payable in U.S. dollars
will be made at the office of the Company's Paying Agent in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount
thereof in U.S. dollars at all offices or agencies outside the United States is
illegal or effectively precluded by exchange controls or other similar
restrictions. (Section 10.2)

         Unless otherwise indicated in an applicable Prospectus Supplement,
payment of the principal of (and premium, if any) and interest on Registered
Securities will be made at the office of such Paying Agent or Paying Agents as
the Company may designate 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 shall appear in the Security
Register.  Unless otherwise indicated in an applicable Prospectus Supplement,
payment of any installment of interest on Registered Securities will be made to
the Person in whose name





                                      -7-
<PAGE>   11
such Registered Security is registered at the close of business on the Regular
Record Date for such interest. (Section 3.7)

         Unless otherwise indicated in an applicable Prospectus Supplement, the
Corporate Trust Office of the Trustee in The City of New York will be
designated as a Paying Agent for the Company for payments with respect to Debt
Securities which are issuable solely as Registered Securities and the Company
will maintain a Paying Agent outside of the United States for payments with
respect to Debt Securities (subject to the limitations described above in the
case of Bearer Securities) which are issuable solely as Bearer Securities or
both Registered Securities and Bearer Securities. (Section 10.2)  Any Paying
Agents outside the United States and any other Paying Agent in the United
States initially designated by the Company for the Debt Securities will be
named in an 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, if Debt Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a Paying Agent in each
Place of Payment for such series and, if Debt Securities of a series are
issuable as Bearer Securities, the Company will be required to maintain (i) a
Paying Agent in the Borough of Manhattan, The City of New York for payments
with respect to any Registered Securities of the series (and for payments with
respect to Bearer Securities of the series in the circumstances described
above, but not otherwise), and (ii) a Paying Agent in a Place of Payment
located outside the United States where Debt Securities of such series and any
coupons appertaining thereto may be presented and surrendered for payment;
provided that if the Debt Securities of such series are listed on The Stock
Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg
Stock Exchange or any other stock exchange located outside the United States
and such stock exchange shall so require, the Company will maintain a Paying
Agent in London or Luxembourg or any other required city located outside the
United States, as the case may be, for the Debt Securities of such series.
(Section 10.2)

         Payments of the principal of (and premium, if any) and interest on
Book-Entry Securities registered in the name of the Depository or its nominee
will be made to the Depository or its nominee, as the case may be, as the
registered owner of the global security representing such Book-Entry
Securities. The Company expects that the Depository, upon receipt of any
payment of the principal of (and premium, if any) or interest on any Debt
Securities, will credit immediately participants' accounts with payments in
amounts proportionate to their respective beneficial interests as shown on the
records of such Depository or its nominee. Neither the Company, the Trustee,
any Paying Agent nor the Securities Registrar for such Debt Securities will
have any responsibility or liability for any aspects of the records relating
to, or payments made on account of, such beneficial ownership interests in the
Book-Entry Securities or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

         All moneys paid by the Company to a Paying Agent for the payment of
the principal of (and premium, if any) or interest on any Debt Securities which
remain unclaimed at the end of two years after such principal, premium or
interest shall have become due and payable will be repaid to the Company and
the Holder of such Debt Security or any coupon will thereafter, as an unsecured
general creditor, look only to the Company for payment thereof. (Section 10.3)

GLOBAL AND BOOK-ENTRY DEBT SECURITIES

         If so specified in an applicable Prospectus Supplement, the portion of
the Debt Securities of a series which are issuable as Bearer Securities will
initially be represented by one or more temporary or permanent global Debt
Securities, without interest coupons, to be deposited with a common depositary
in London for the benefit of the Euroclear System ("Euroclear") and Cedel Bank,
Societe Anonyme ("Cedel") for credit to the respective accounts of the
beneficial owners of such Debt Securities (or to such other accounts as they
may direct).  (Section 3.4)  Unless otherwise indicated by an applicable
Prospectus Supplement, on or after 40 days following its issuance, each such
temporary global Debt Security will be exchangeable for definitive Bearer
Securities, definitive Registered Securities or all or a portion of a permanent
global Debt Security, or any





                                      -8-
<PAGE>   12
combination thereof, as specified in an applicable Prospectus Supplement, only
upon written certification in the form and to the effect described under "Form,
Exchange, Registration and Transfer." No Bearer Security (including a Debt
Security in permanent global form) delivered in exchange for a portion of a
temporary or permanent global Debt Security shall be mailed or otherwise
delivered to any location in the United States in connection with such
exchange. (Section 3.5)

         A person having a beneficial interest in a permanent global Debt
Security will, except with respect to payment of the principal of (and premium,
if any) and interest on such permanent global Debt Security, be treated as a
Holder of such principal amount of Outstanding Debt Securities represented by
such permanent global Debt Security as shall be specified in a written
statement of the Holder of such permanent global Debt Security or, in the case
of a permanent global Debt Security in bearer form, of the operator of
Euroclear or Cedel which is provided to the Trustee by such Person. (Section
2.3)

         If Debt Securities to be sold in the United States are designated by
the Company in a Prospectus Supplement as Book-Entry Securities, a global
security representing the Book-Entry Securities will be deposited in the name
of Cede & Co., as nominee for the Depository representing the securities to be
sold in the United States. Upon such deposit of the Book-Entry Securities, the
Depository shall credit an account maintained or designated by an institution
to be named by the Company or any purchaser of the Debt Securities represented
by the Book-Entry Securities with an aggregate amount of Debt Securities equal
to the total number of Debt Securities that have been so purchased. The
specific terms of any depository arrangement with respect to any portion of a
series of Debt Securities to be represented by one or more global securities
will be described in the applicable Prospectus Supplement. Beneficial interests
in such Debt Securities will only be evidenced by, and transfers thereof will
only be effected through, records maintained by the Depository and the
institutions that are Depository participants.

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. (Section 15.1 of the Subordinated Indenture)  In
the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding
in connection therewith, relative to the Company or to its creditors, as such,
or to its assets, or (b) any liquidation, dissolution or other winding up of
the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling 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 cash, before the Holders of
Subordinated Debt Securities are entitled to receive any payment on account of
principal of (or premium, if any) or interest on Subordinated Debt Securities,
and to that end the holders of Senior Debt 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, including any such payment
or distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of
Subordinated Debt Securities, which may be payable or deliverable in respect of
the Subordinated Debt Securities in any such case, proceeding, dissolution,
liquidation or other winding up event. (Section 15.2 of the Subordinated
Indenture)

         By reason of such subordination, in the event of liquidation or
insolvency, creditors of the Company may recover less, ratably, than Holders of
Senior Debt and may recover more, ratably, than the Holders of the Subordinated
Debt Securities.





                                      -9-
<PAGE>   13
         In the event of the acceleration of the maturity of any Subordinated
Debt Securities, the Holders of all Senior Debt outstanding at the time of such
acceleration will first be entitled to receive payment in full of all amounts
due thereon before the Holders of the Subordinated Debt Securities will be
entitled to receive any payment upon the principal of (and premium, if any) or
interest on, the Subordinated Debt Securities. (Section 15.3 of the
Subordinated Indenture)

         No payments on account of the principal of (and premium, if any) or
interest in respect of the Subordinated Debt Securities may be made if there
shall have occurred and be continuing a default in any payment with respect to
Senior Debt, or an event of default with respect to any Senior Debt resulting
in the acceleration of the maturity thereof, or if any judicial proceeding
shall be pending with respect to any such default. (Section 15.4 of the
Subordinated Indenture) For purposes of the subordination provisions, 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 15.14 of the
Subordinated Indenture)

         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 constitute Senior Debt under the
Subordinated Indenture.

         "Senior Debt" is defined to include the principal of (and premium, if
any) and interest (including interest accrued 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 all indebtedness of the Company (including indebtedness of
others guaranteed by the Company), other than the Company's 5-1/4% Convertible
Subordinated Debentures due 2003, the Securities and any other obligations
specifically designated as being subordinate in right of payment to Senior
Debt, whether outstanding on the date of the Subordinated Indenture or
thereafter created, incurred or assumed, which is for money borrowed or
evidenced by bonds, debentures, notes or similar instruments and amendments,
renewals, extensions, modifications and refundings of any such indebtedness or
obligation.  (Section 1.1 of the Subordinated Indenture)

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

CONVERSION OR EXCHANGE RIGHTS

         The terms on which Debt Securities of any series are convertible into
or exchangeable for Common Stock or other securities of the Company will be set
forth in the Prospectus Supplement relating thereto. Such terms will include
provisions as to whether conversion or exchange is mandatory, at the option of
the Holder or at the option of the Company, and may include provisions pursuant
to which the number of shares of Common Stock or other securities of the
Company to be received by the Holders of Debt Securities would be subject to
adjustment. (Section 3.1 and Article XIV)

CERTAIN COVENANTS

          Negative Pledge.  The Senior Debt Indenture provides that the Company
and any successor corporation will not, and will not permit any Subsidiary (as
defined in such Indenture) to create, assume, incur or guarantee any
indebtedness for borrowed money secured by a pledge, lien or other encumbrance
(except for certain liens specifically permitted by such Indenture) on the
Voting Securities (as defined in such Indenture) of Legg Mason Wood Walker
without making effective provision whereby the Debt Securities issued under
such Indenture will be secured equally and ratably with such secured
indebtedness.  (Senior Debt Indenture, Section 10.7)





                                      -10-
<PAGE>   14
         Unless otherwise specified in the Prospectus Supplement, the
Indentures contain no other restrictive covenants or other provisions providing
for a put or increased interest or otherwise, including any that would afford
holders of the Debt Securities protection in the event of a highly leveraged
transaction involving the Company or any of its affiliates, or any covenants
relating to total indebtedness, interest coverage, stock repurchases,
recapitalizations, dividends and distributions to shareholders, current ratios
and acquisitions and divestitures.

         Consolidation, Merger or Sale of Assets.  The Company, without the
consent of the Holders of any of the Outstanding Debt Securities under the
applicable Indenture, may consolidate with or merge with or into, or sell,
lease, transfer or otherwise dispose of its assets substantially as an entirety
to, any Person which is a corporation, partnership or trust organized and
validly existing under the laws of any domestic jurisdiction, or may permit any
such Person to consolidate with or merge with or into the Company or sell,
lease, transfer or otherwise dispose of its assets substantially as an entirety
to the Company, provided that, among other things, any successor Person assumes
the Company's obligations on the Debt Securities and under the applicable
Indenture, that after giving effect to the transaction no Event of Default, and
no event which, after notice or lapse of time, would become an Event of
Default, shall have occurred and be continuing, and that certain other
conditions are met. (Section 8.1)

EVENTS OF DEFAULT

         An Event of Default is defined under each Indenture with respect to
Debt Securities or any series issued under such Indenture as being:  (a)
default in payment of any principal of the Debt Securities of such series,
either at maturity (or upon any redemption), by declaration or otherwise; (b)
default for 30 days in payment of any interest on any Debt Securities of such
series; (c) default for 60 days after written notice in the observance or
performance of any other covenant or agreement in the Debt Securities of such
series or such Indenture other than a covenant included in such Indenture
solely for the benefit of a series of Debt Securities other than such series;
(d) certain events of bankruptcy, insolvency or reorganization involving the
Company; (e) failure by the Company to make any payment at maturity, including
any applicable grace period, in respect of indebtedness, which term as used in
each of the Indentures means obligations (other than non-recourse obligations
or the Debt Securities of such series issued under such Indenture) of, or
guaranteed or assumed by, the Company for borrowed money or evidenced by bonds,
debentures, notes or other similar instruments ("Indebtedness") in an amount in
excess of $10,000,000 and continuance of such failure for a period of 30 days
after written notice thereof to the Company by the Trustee, or to the Company
and the Trustee by the Holders of not less than 25% in principal amount of such
outstanding Debt Securities (treated as one class) issued under such Indenture;
or (f) a default with respect to any Indebtedness, which default results in the
acceleration of Indebtedness in an amount in excess of $10,000,000 without such
Indebtedness having been discharged or such acceleration having been cured,
waived, rescinded or annulled for a period of 30 days after written notice
thereof to the Company by the Trustee, or to the Company and the Trustee by the
Holders of not less than 25% in principal amount of such outstanding Debt
Securities (treated as one class) issued under such Indenture; provided,
however, that if any such failure, default or acceleration referred to in
clause (e) or clause (f) above shall cease or be cured, waived, rescinded or
annulled, then the Event of Default by reason thereof shall be deemed likewise
to have been thereupon cured.  (Section 5.1)

         Each Indenture provides that (a) if an Event of Default due to the
default in payment of principal of, premium, if any, or interest on, any series
of Debt Securities issued under such Indenture or due to the default in the
performance or breach of any other covenant or warranty of the Company
applicable to the Debt Securities of such series but not applicable to all
outstanding Debt Securities issued under such Indenture shall have occurred and
be continuing, either the Trustee or the Holders of not less than 25% in
principal amount of such Debt Securities of each affected series issued under
such Indenture and then outstanding may then declare the principal of all Debt
Securities of each such affected series and interest accrued thereon to be due
and payable immediately; and (b) if an Event of Default due to a default in the
performance of any other of the





                                      -11-
<PAGE>   15
covenants or agreements in such Indenture applicable to all outstanding Debt
Securities issued under such Indenture and then outstanding or due to certain
events of bankruptcy, insolvency and reorganization of the Company shall have
occurred and be continuing, either the Trustee or the Holders of not less than
25% in principal amount of all Debt Securities issued under such Indenture and
then outstanding (treated as one class) may declare the principal of all such
Debt Securities and interest accrued thereon to be due and payable immediately,
but upon certain conditions such declarations may be annulled and past defaults
may be waived (except a continuing default in payment of principal of (or
premium, if any) or interest on such Debt Securities) by the Holders of a
majority in principal amount of the Debt Securities of all such affected series
then outstanding.  (Section 5.2)

         Each Indenture provides that no holder of Debt Securities issued under
such Indenture may institute any action against the Company under such
Indenture (except actions for payment of overdue principal or interest) unless
such Holder previously shall have given to the Trustee written notice of
default and continuance thereof and unless the Holders of not less than 25% in
principal amount of the Debt Securities of each affected series (treated as one
class) issued under such Indenture and then outstanding shall have requested
the Trustee to institute such action and shall have offered the Trustee
reasonable indemnity, the Trustee shall not have instituted such action within
60 days of such request and the Trustee shall not have received direction
inconsistent with such written request by the Holders of a majority in
principal amount of the Debt Securities of each affected series (treated as one
class) issued under such Indenture and then outstanding.  (Sections 5.9 and
5.12)

         Each Indenture contains a covenant that the Company will file annually
with the Trustee a certificate of no default or a certificate specifying any
default that exists.  (Section 10.8 of the Senior Indenture; Section 10.7 of
the Subordinated Indenture)

DEFEASANCE AND DISCHARGE

         If so specified with respect to any particular series of Debt
Securities, the Company may discharge its indebtedness and its obligations or
certain of its obligations under the applicable Indenture with respect to such
series by depositing funds or obligations issued or guaranteed by the United
States of America with the Trustee.  (Section 4.3)

         The Indentures provide that, if so specified with respect to the Debt
Securities of any series, the Company will be discharged from any and all
obligations in respect of the Debt Securities of such series (including, in the
case of Subordinated Debt Securities, the subordination provisions described
under "Subordination of Subordinated Debt Securities" herein and, except for
certain obligations relating to temporary Debt Securities and exchange of Debt
Securities, registration of transfer or exchange of Debt Securities of such
series, replacement of stolen, lost or mutilated Debt Securities of such
series, maintenance of paying agencies to hold monies for payment in trust and
payment of additional amounts, if any, required in consequence of United States
withholding taxes imposed on payments to non-United States persons) upon the
deposit with the Trustee, in trust, of money and/or U.S. Government Obligations
which through the payment of interest and principal in respect thereof in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium, if any), each installment of interest on, and
any sinking fund payments on, the Debt Securities of such series on the Stated
Maturity of such payments in accordance with the terms of the applicable
Indenture and the Debt Securities of such series.  (Section 4.6)  Such a trust
may only be established if, among other things, (a) the Company has delivered
to the applicable Trustee an Opinion of Counsel to the effect that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of the applicable Indenture there has
been a change in applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the
Holders of Debt Securities of such series will not recognize income, 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 amounts
and in the same manner and at the same times as would have been the case if
such deposit, defeasance and discharge had





                                      -12-
<PAGE>   16
not occurred; (b) the Debt Securities of such series, if then listed on any
domestic or foreign securities exchange, will not be delisted as a result of
such deposit, defeasance and discharge; and (c) in the case of the Subordinated
Debt Securities, (x) no default in the payment of the principal of (and
premium, if any) or any interest on any Senior Debt beyond any applicable grace
period shall have occurred and be continuing, or (y) no other default with
respect to any Senior Debt shall have occurred and be continuing and shall have
resulted in the acceleration of such Senior Debt.  In the event of any such
defeasance and discharge of Debt Securities of such series, Holders of Debt
Securities of such series would be able to look only to such trust fund for
payment of principal of and any premium and any interest on their Debt
Securities until Maturity. (Section 4.6)

DEFEASANCE OF CERTAIN OBLIGATIONS

         The Indentures provide that, if so specified with respect to the Debt
Securities of any series, the Company may omit to comply with any covenants
applicable to such Debt Securities which are subject to covenant defeasance and
any such omission shall not be an Event of Default with respect to the Debt
Securities of such series, upon the irrevocable deposit with the Trustee, in
trust, of money and/or U.S. Government Obligations which through the payment of
interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of (and premium, if
any), each installment of interest on and any sinking fund payments thereof on
the Debt Securities of such series on the Stated Maturity of such payments or
upon optional redemption and any mandatory sinking fund payments or analogous
payments on the Debt Securities of such series on the day on which such
payments are due and payable in accordance with the terms of the applicable
Indenture and the Debt Securities of such series.  (Sections 4.5 and 4.6 )  The
obligations of the Company under the  applicable Indenture and the Debt
Securities of such series other than with respect to such covenants shall
remain in full force and effect.  (Section 4.5)  Such a trust may be
established only if, among other things, the Company has delivered to the
Trustee an Opinion of Counsel to the effect that (i) the Holders of the Debt
Securities of such series will not recognize income, gain or loss for federal
income tax purposes as a result of such deposit, defeasance and discharge of
certain obligations and will be subject to federal income tax on the same
amount and in the same manner and at the same times as would have been the case
if such deposit, defeasance and discharge had not occurred and (ii) the Debt
Securities of such series, if then listed on any domestic or foreign securities
exchange, will not be delisted as a result of such deposit, defeasance and
discharge.  (Section 4.6)

         In the event the Company exercises its option to omit compliance with
the covenants described under "Covenants" above with respect to the Debt
Securities of any series or in any Prospectus Supplement with respect to the
Debt Securities of such series and such Debt Securities are declared due and
payable because of the occurrence of any Event of Default, then the amount of
money and U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Debt Securities of such series at the time
of their Stated Maturity but may not be sufficient to pay amounts due on the
Debt Securities of such series at the time of the acceleration resulting from
such Default. The Company shall in any event remain liable for such payments as
provided in the Indentures.

         The Trustee must deliver or pay to the Company from time to time, upon
request of the Company, any amounts held by it with respect to any Securities
which, in the opinion of a nationally recognized firm of independent public
accountants, are in excess of the amount which would then be required to be
deposited to effect a satisfaction, discharge or defeasance, as the case may
be, with respect to such Securities.

MEETINGS, MODIFICATION AND WAIVER

         Each Indenture provides that the Company and the Trustee may enter
into supplemental indentures without the consent of the Holders to:  (a) secure
any Debt Securities, (b) evidence the assumption by a successor corporation of
the obligations of the Company, (c) add covenants for the protection of the
Holders of Debt Securities, (d) cure any ambiguity or correct any inconsistency
in such Indenture, (e) establish the forms





                                      -13-
<PAGE>   17
or terms of Debt Securities of any series and (f) evidence the acceptance of
appointment by a successor trustee.  (Section 9.1)

         Modifications and amendments of the Indentures may also be made by the
Company and the Trustee under the applicable Indenture with the consent of the
Holders of not less than a majority in principal amount of the Outstanding Debt
Securities issued under the applicable Indenture and affected by such
modification or amendment (voting as one class) unless a greater percentage of
such principal amount is specified in the applicable Prospectus Supplement;
provided, however, that no such modification or amendment may, without the
consent of each Holder of each Outstanding Debt Security affected thereby, (a)
change the Stated Maturity of the principal of, or any installment of principal
of or interest on, any such Debt Security, (b) reduce the principal amount of
(and premium, if any) or interest on, any such Debt Security, (c) change any
obligation of the Company to pay additional amounts, (d) reduce the amount of
principal of an Original Issue Discount Security or any other Debt Security
payable upon acceleration of the maturity thereof, (e) change the coin or
currency in which any Debt Security or any premium or interest thereon is
payable, (f) impair the right to institute suit for the enforcement of any
payment on or with respect to any such Debt Security, (g) adversely change the
right to convert or exchange, including decreasing the conversion rate or
increasing the conversion price of, such Debt Security (if applicable), (h) in
the case of the Subordinated Indenture, modify the subordination provisions in
a manner adverse to the Holders of the Subordinated Debt Securities, (i) reduce
the percentage in principal amount of Outstanding Debt Securities of any
series, the consent of whose Holders is required for modification or amendment
of the applicable Indenture or for waiver of compliance with certain provisions
of the applicable Indenture or for waiver of certain defaults, (j) reduce the
requirements contained in the applicable Indenture for quorum or voting, (k)
change any obligations of the Company to maintain an office or agency in the
places and for the purposes required by the Indentures, or (l) modify any of
the above provisions. (Section 9.2)

         The Holders of at least a majority in principal amount of the
Outstanding Debt Securities of each series may, on behalf of the Holders of all
the Debt Securities of that series, waive, insofar as that series is concerned,
compliance by the Company with certain restrictive provisions of the applicable
Indenture and, if applicable, such Debt Securities, unless a greater percentage
of such principal amount is specified in the applicable Prospectus Supplement.
The Holders of not less than a majority in principal amount of the Outstanding
Debt Securities of each series may, on behalf of all Holders of Debt Securities
of that series and any coupons pertaining thereto, waive any past default under
the applicable Indenture, except a default (a) in the payment of principal of
(and premium, if any) or any interest on any Debt Security of such series, and
(b) in respect of a covenant or provision of the applicable Indenture and, if
applicable, such Debt Securities, which cannot be modified or amended without
the consent of the Holder of each Outstanding Debt Security of such series
affected. (Section 5.13)

         The Indentures provide that in determining whether the Holders of the
requisite principal amount of the Outstanding Debt Securities have given any
request, demand, authorization, direction, notice, consent or waiver thereunder
or are present at a meeting of Holders of Debt Securities for quorum purposes,
(i) the principal amount of an Original Issue Discount Security that shall be
deemed to be Outstanding shall be the amount of the principal thereof that
would be due and payable as of the date of such determination upon acceleration
of the Maturity thereof, and (ii) the principal amount of a Debt Security
denominated in a foreign currency or currency units shall be the U.S. dollar
equivalent, determined on the date of original issuance of such Debt Security,
of the principal amount of such Debt Security or, in the case of an Original
Issue Discount Security, the U.S. dollar equivalent, determined on the date of
original issuance of such Debt Security, of the amount determined as provided
in (i) above.

         The Indentures contain provisions for convening meetings of the
Holders of Debt Securities of a series if Debt Securities of that series are
issuable as Bearer Securities.  A meeting may be called at any time by the
Trustee, and also, upon request, by the Company or the Holders of at least 25%
in principal amount of the Outstanding Debt Securities of such series, in any
such case upon notice given in accordance with "Notices"





                                      -14-
<PAGE>   18
below. (Sections 13.1 and 13.2) Except for any consent which must be given by
the Holder of each Outstanding Debt Security affected thereby, as described
above, any resolution presented at a meeting or adjourned meeting at which a
quorum is present may be adopted by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Debt Securities of that series;
provided, however, that, except for any consent which must be given by the
Holder of each Outstanding Debt Security affected thereby, as described above,
any resolution with respect to any consent or waiver which may be given by the
Holders of not less than a majority in principal amount of the Outstanding Debt
Securities of a series may be adopted at a meeting or an adjourned meeting at
which a quorum is present only by the affirmative vote of a majority in
principal amount of the Outstanding Debt Securities of that series; and
provided, further, that, except for any consent which must be given by the
Holder of each Outstanding Debt Security affected thereby, as described above,
any resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which may be made, given or taken by
the Holders of a specified percentage, which is less than a majority in
principal amount of the Outstanding Debt Securities of a series may be adopted
at a meeting or adjourned meeting duly reconvened at which a quorum is present
by the affirmative vote of the Holders of such specified percentage in the
principal amount of the Outstanding Debt Securities of that series. Any
resolution passed or decision taken at any meeting of Holders of Debt
Securities of any series duly held in accordance with the applicable Indenture
will be binding on all Holders of Debt Securities of that series and the
related coupons. The quorum at any meeting called to adopt a resolution or with
respect to a consent or a waiver which may be given by the Holders of not less
than a majority in principal amount of the Outstanding Debt Securities of a
series, and at any reconvened meeting, will be persons holding or representing
a majority in principal amount of the Outstanding Debt Securities of a series;
provided, however, that if any action is to be taken at such meeting with
respect to a consent or waiver which may be given by the Holders of less or
greater than a majority in principal amount of the Outstanding Debt Securities
of a series then, with respect to such action (and only such action) the
Holders entitled to vote such lesser or greater percentage in principal amount
of the Outstanding Securities of such series shall constitute a quorum.
(Section 13.4)

NOTICES

         Except as otherwise provided in the applicable Indenture, notices to
Holders of Bearer Securities will be given by publication at least twice in a
daily newspaper in The City of New York and in such other city or cities as may
be specified in such Debt Securities.  Notices to Holders of Registered
Securities will be given by mail to the address of such Holders as they appear
in the Security Register. (Section 1.6)

TITLE

         Title to any temporary global Debt Security, any Bearer Securities
(including Bearer Securities in permanent global form) and any coupons
appertaining thereto will pass by delivery.  The Company, the Trustee and any
agent of the Company or the Trustee may treat the bearer of any Bearer Security
and the bearer of any coupon and the registered owner of any Registered
Security as the absolute owner thereof (whether or not such Debt Security or
coupon shall be overdue and notwithstanding any notice to the contrary) for the
purpose of making payment and for all other purposes. (Section 3.8)

REPLACEMENT OF DEBT SECURITIES AND COUPONS

         Any mutilated Debt Security or a Debt Security with a mutilated coupon
appertaining thereto will be replaced by the Company at the expense of the
Holder upon surrender of such Debt Security to the Trustee. Debt Securities or
coupons that became destroyed, stolen or lost will be replaced by the Company
at the expense of the Holder upon delivery of the Trustee of the Debt Security
and coupons or evidence of the destruction, loss or theft thereof satisfactory
to the Company and the Trustee; in the case of any coupon which becomes
destroyed, stolen or lost, such coupon will be replaced by issuance of a new
Debt Security in exchange for the Debt Security to which such coupon
appertains.  In the case of a destroyed, lost or stolen Debt Security





                                      -15-
<PAGE>   19
or coupon, an indemnity satisfactory to the Trustee and the Company may be
required at the expense of the Holder of such Debt Security or coupon before a
replacement Debt Security will be issued. (Section 3.6)

GOVERNING LAW

         The Indentures, the Debt Securities and the coupons will be governed
by, and construed in accordance with, the laws of the State of New York without
regard to principles of conflicts of laws. (Section 1.13)

REGARDING THE TRUSTEE

         The Indentures contain limitations on the right of a Trustee, as a
creditor of the Company, to obtain payment of claims in certain cases or to
realize on certain property received in respect of any such claim as security
or otherwise. (Section 6.11) In addition, a Trustee may be deemed to have a
conflicting interest and may be required to resign as Trustee if at the time of
a default under one of the Indentures it is a creditor of the Company. (Section
6.9) The Company and its subsidiaries may from time to time maintain deposit
accounts and credit facilities and conduct its banking transactions with a
Trustee in the ordinary course of business. (Section 6.4)  In addition, The
Bank of New York, which may act as a Trustee under the Indentures, acts as
trustee under an indenture, dated as of May 1, 1993, related to the Company's 5
1/4% Convertible Subordinated Debentures due 2003.


                          DESCRIPTION OF CAPITAL STOCK

         The authorized capital stock of the Company consists of 20,000,000
shares of Common Stock, par value $.10 per share, and 4,000,000 shares of
Preferred Stock, par value $10.00 per share.  As of December 31, 1995, there
were 14,006,872 shares of Common Stock and no shares of Preferred Stock
outstanding.  Prior to the issuance of Convertible Debt Securities under the
Indentures, the Company may need to increase its authorized Common Stock, which
would require the approval of its stockholders.

COMMON STOCK

         Holders of Common Stock are entitled to one vote per share on matters
to be voted upon by the stockholders, to receive dividends out of funds legally
available for distribution when and if declared by the Board of Directors and
to share ratably in the assets of the Company legally available for
distribution to its stockholders in the event of liquidation, dissolution or
winding up of the Company, after provisions for distributions to the holders of
any Preferred Stock.

         The Company may not pay any dividend (other than in shares of Common
Stock) or make any distributions of assets on shares of Common Stock until
cumulative dividends on any Preferred Stock then outstanding have been paid.

         Holders of Common Stock have no preemptive, subscription, redemption
or conversion rights.  The outstanding shares of Common Stock are, and the
shares which may be issued upon conversion of the Convertible Debt Securities
will be, when issued, fully paid and nonassessable.

         The holders of the Common Stock do not have cumulative voting rights,
which means that holders of more than half of the shares can elect all of the
directors and holders of the remaining shares will not be able to elect any
directors.  The Company's By-laws provide for a classified board of directors
consisting of three classes with staggered three-year terms.

TRANSFER AGENT





                                      -16-
<PAGE>   20
         The transfer agent and registrar for the Company's Common Stock is
First Union National Bank of North Carolina, Charlotte, North Carolina.

PREFERRED STOCK

         The Company's Articles authorize the Board of Directors to issue
shares of Preferred Stock, par value $10.00 per share, and to fix the terms
(including voting rights, dividends, redemption and conversion provisions, if
any, and rights upon liquidation) of any shares issued.  Outstanding shares of
Preferred Stock which are redeemed or are converted to Common Stock are
restored to the status of authorized and unissued shares of Preferred Stock
issuable in series by the Board of Directors of the Company.  There are
presently no shares of Preferred Stock outstanding.

         The Board of Directors has the authority, under the Company's Articles
of Incorporation, to classify or reclassify any unissued Preferred Stock from
time to time by setting or changing the preferences, conversion or other
rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption of the stock.

TWO-TIER BUSINESS COMBINATION PROVISIONS

         Maryland law requires the affirmative vote of at least a majority of
all of the outstanding shares entitled to vote to approve a merger,
consolidation, share exchange or disposition of all or substantially all of the
Company's assets.  The Company's Articles require the affirmative vote of not
less than 70% of the then outstanding voting shares of the Company to approve
any "business combination" of the Company with any "Related Person" unless
certain conditions have been met.  In addition, the 70% vote must include the
affirmative vote of at least 55% of the outstanding shares of voting stock held
by stockholders other than the Related Person.  Accordingly, the actual vote
required to approve the business combination may be greater than the 70%,
depending upon the number of shares controlled by the Related Person.  A
Related Person is defined to include any person or entity which is, directly or
indirectly, the beneficial owner of 15% or more of the outstanding shares of
the Company's voting stock, including any affiliate or associate of such person
or entity. The term "business combination" is defined to include a wide variety
of transactions between the Company and a Related Person, including a merger,
consolidation, share exchange or sale of assets having a fair market value
greater than 10% of the book value of the Company's consolidated assets.

         However, if the Related Person pays a "fair price" to the Company's
stockholders in the transaction, the 70% requirement would not be applicable
and the proposed business combination could be approved by a simple majority of
the stockholders unless otherwise required by Maryland law, provided that such
affirmative vote includes at least 55% of the voting stock held by persons
other than the Related Person.  Under the Articles, the "fair price" must be at
least equal to the greater of the highest price paid or agreed to be paid by
the Related Person to purchase shares of the Company's Common Stock, or the
highest market price of the Common Stock, in each case during the 24-month
period prior to the taking of such vote, or the per share book value of the
Common Stock at the end of the calendar quarter immediately preceding the
taking of such vote. In addition, the "fair price" consideration to be received
by the Company's stockholders must be of the same form and kind as the most
favorable form and kind of consideration paid by the Related Person in
acquiring any of its shares of Common Stock of the Company.

         The special voting provisions are not applicable to a business
combination authorized by the Board of Directors by a vote which includes a
majority of the "Disinterested Directors" of the Company.  A Disinterested
Director is defined to include any member of the Board of Directors who is not
the Related Person (or an affiliate or associate of the Related Person) and who
was a Director prior to the time that the Related Person became a Related
Person, and any successor of a Disinterested Director who is not the Related
Person (or an affiliate or associate of the Related Person) and who is
recommended to succeed a Disinterested Director by a majority of the
Disinterested Directors then on the Board.





                                      -17-
<PAGE>   21
         These special voting provisions may not be amended, altered, changed
or repealed except by the affirmative vote of at least 70% of the shares of
stock entitled to vote at a meeting of the stockholders called for the
consideration of such amendment, alteration, change or repeal, and at least 55%
of the outstanding shares of stock entitled to vote thereon held by
stockholders who are not Related Persons, unless such proposal shall have been
proposed by the Board of Directors by a vote which includes a majority of the
Disinterested Directors.

         The business combination provisions under the Company's charter could
have the effect of delaying, deterring or preventing a change in control of the
Company.  Any possible change in control could also be affected by the
applicability of certain Maryland anti-takeover statutes dealing with business
combinations and acquisitions of controlling blocks of shares, as well as by
the Company's classified board of director provisions.

                  LIMITATIONS ON ISSUANCE OF BEARER SECURITIES

         In compliance with United States federal tax laws and regulations,
Bearer Securities (including Debt Securities that are exchangeable for Bearer
Securities and Debt Securities in permanent global form that are either Bearer
Securities or exchangeable for Bearer Securities) may not be offered, sold,
resold or delivered in connection with their original issuance in the United
States or to United States persons (each as defined below) except as otherwise
permitted by Treasury Regulation Section 1.163-5(c)(2)(i)(D) including offers
and sales to offices located outside the United States of United States
financial institutions (as defined in Treasury Regulation Section
1.165-12(c)(1)(v)) which agree in writing to comply with the requirements of
Section 165(j)(3)(A), (B) or (C) of the Code, as defined below, and the
regulations thereunder, and any underwriters, agents and dealers participating
in the offering of Debt Securities must agree in writing that they will not
offer, sell or resell any Bearer Securities to persons within the United States
or to United States persons (except as described above) nor deliver Bearer
Securities within the United States.  In addition, any such underwriters,
agents and dealers must represent in writing that they have in effect, in
connection with the offer and sale of the Debt Securities, procedures
reasonably designed to ensure that their employees or agents who are directly
engaged in selling the Debt Securities are aware that Bearer Securities cannot
be offered or sold to a person who is within the United States or is a United
States person except as otherwise permitted by Treasury Regulation Section
1.163-5(c)(2)(i)(D). Furthermore, the owner of the obligation (or the financial
institution or clearing organization through which the owner holds the
obligation) must certify to the Company that the owner is not a United States
person.  Bearer Securities and any coupons attached thereto will bear the
following legend: "Any United States person who holds this obligation will be
subject to limitations under the United States income tax laws, including the
limitations provided in Sections 165(j) and 1287(a) of the United States
Internal Revenue Code." Purchasers of Bearer Securities may be affected by
certain limitations under United States tax laws.

         As used herein, "United States person" means (i) an individual who is,
for United States Federal income tax purposes, a citizen or resident of the
United States, (ii) a corporation, partnership or other entity created or
organized in or under the laws of the United States or of any political
subdivision thereof, or (iii) an estate or trust the income of which is subject
to United States Federal income taxation regardless of its source, and "United
States" means the United States of America (including the States and the
District of Columbia), its territories and its possessions.


                                 ERISA MATTERS

                 The Employee Retirement Income Security Act of 1974, as
amended ("ERISA") and the Internal Revenue Code of 1986, as amended (the
"Code") impose certain restrictions on (1) "employee benefit plans" (as defined
in Section 3(3) of ERISA), (2) "plans" described in Section 4975(e)(1) of the
Code, including individual retirement accounts or Keogh plans, (3) entities
whose underlying assets include plan assets by reason of a plan's investment in
such entities (each of (a), (b) and (c) a "Plan") and (4) persons who have
certain specified relationships to Plans ("parties in interest" under ERISA and
"disqualified persons" under the Code).





                                      -18-
<PAGE>   22
ERISA also imposes certain duties on persons who are fiduciaries of Plans
subject to ERISA, and both ERISA and the Code prohibit certain transactions
between a Plan and parties in interest or disqualified persons.

                 Because of its activities or the activities of its affiliates,
the Company may be deemed to be a party in interest or disqualified person with
respect to a number of Plans, e.g., those to which it provides brokerage,
investment or other financial services.  If the Securities are acquired and
held by a Plan with respect to which the Company is a party in interest or
disqualified person, such acquisition and holding could be deemed to be a
direct or indirect prohibited transaction, which could result in the imposition
of taxes or penalties on the parties to the prohibited transaction.

                 Such transactions may, however, be exempt from the otherwise
applicable taxes and penalties by reason of one or more statutory or
administrative exemptions such as those described below.  Such administrative
exemptions may include Prohibited Transaction Class Exemption ("PTE") 95-60, 60
FR 35925, July 12, 1995, which exempts certain transactions involving insurance
company general accounts; PTE 90-1, 55 FR 2891, January 29, 1990, which exempts
certain transactions involving insurance company pooled separate accounts; PTE
91-38, 56 FR 31966, June 12, 1991, which exempts certain transactions involving
bank collective investment funds; and PTE 84-14, 49 FR 9494, March 13, 1984,
which exempts certain transactions entered into on behalf of a Plan by a
qualified professional asset manager.  If the conditions of one or more of
these exemptions (or some other applicable exemption) are met, the acquisition
and holding of the Securities by or on behalf of a Plan should be exempt from
certain of the prohibited transaction provisions of ERISA and the Code.  It
should be noted, however, that even if such conditions are met, the scope of
relief provided by such exemptions may not necessarily cover all acts that
might be construed as prohibited transactions under ERISA and the Code.

                 Further, each Plan fiduciary should take into account, among
other considerations, whether the fiduciary has the authority to make the
investment; whether the investment constitutes a direct or indirect transaction
with a party in interest or disqualified person; the composition of the Plan's
portfolio with respect to diversification by type of asset; the Plan's funding
objectives; the tax effects of the investment; and whether under the general
fiduciary standards of investment procedure and diversification an investment
in the Securities is appropriate for the Plan, taking into account the overall
investment policy of the Plan, the composition of the Plan's investment
portfolio and all other appropriate factors.

                 Prior to making an investment in the Securities, a Plan
investor must determine whether the Company is a party in interest or
disqualified person with respect to such Plan and, if so, whether such
transaction is subject to one or more statutory or administrative exemptions,
including those described above, and whether the investment is otherwise a
permissible and appropriate investment for the Plan.  Prospective investors
should consult with their legal and other advisors concerning the impact of
ERISA and the Code and the potential consequences of such investment with
respect to their specific circumstances.


                              PLAN OF DISTRIBUTION

         The Company may sell Securities to or through underwriters or dealers,
which may include Legg Mason Wood Walker, Goldman, Sachs & Co., Lehman Brothers
Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley &
Co. Incorporated,  directly to other purchasers, or through agents.  The
Prospectus Supplement with respect to the Securities will set forth the terms
of the offering of the Securities, including the name or names of any
underwriters, dealers or agents, the price of the offered Securities and the
net proceeds to the Company from such sale, any underwriting discounts or other
items constituting underwriters' compensation, any discounts or concessions
allowed or reallowed or paid to dealers and any securities exchanges on which
the Securities may be listed.

<PAGE>   23
         If underwriters are used in the sale, the Securities will be acquired
by the underwriters for their own account and may be resold from time to time
in one or more transactions, including negotiated transactions, at a fixed
public price or at varying prices determined at the time of sale.  The
underwriter or underwriters with respect to a particular underwritten offering
of Securities will be named in the Prospectus Supplement relating to such
offering, and if an underwriting syndicate is used, the managing underwriter or
underwriters will be set forth on the cover of such Prospectus Supplement.
Unless otherwise set forth in the Prospectus Supplement, the obligations of the
underwriters or agents to purchase the Securities will be subject to certain
conditions precedent and the underwriters will be obligated to purchase all the
Securities if any are purchased.  Any initial public offering price and any
discounts or concessions allowed or reallowed or paid to dealers may be changed
from time to time.

         If a dealer is utilized in the sale of any Securities in respect of
which this Prospectus is delivered, the Company will sell such Securities to
the dealer, as principal.  The dealer may then resell such Securities to the
public at varying prices to be determined by such dealer at the time of resale.
The name of the dealer and the terms of the transaction will be set forth in
the Prospectus Supplement relating thereto.

         Securities may be sold directly by the Company to one or more
institutional purchasers, or through agents designated by the Company from time
to time, at a fixed price, or prices, which may be changed, or at varying
prices determined at time of sale.  Any agent involved in the offer or sale of
the Securities will be named, and any commissions payable by the Company to
such agent will be set forth, in the Prospectus Supplement relating thereto.
Unless otherwise indicated in the Prospectus Supplement, any such agent will be
acting on a best efforts basis for the period of its appointment.

         In connection with the sale of the Securities, underwriters or agents
may receive compensation from the Company or from purchasers of Securities for
whom they may act as agents in the form of discounts, concessions, or
commissions.  Underwriters, agents, and dealers participating in the
distribution of the Securities may be deemed to be underwriters, and any
discounts or commissions received by them from the Company and any profit on
the resale of the Securities by them may be deemed to be underwriting discounts
or commissions under the Securities Act.

         Each underwriter, dealer and agent participating in the distribution
of any Debt Securities which are issuable in bearer form will agree that it
will not offer, sell or deliver, directly or indirectly, Debt Securities in
bearer form in the United States or to United States persons except as
otherwise permitted by Treasury Regulation Section 1.163-5(c)(2)(i)(D).  See
"Limitations on Issuance of Bearer Securities."

         Each underwriter, dealer and agent participating in the distribution
of any Securities will agree that (a) it will not offer or sell any Securities
to persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which do not constitute an offer to the public in the United
Kingdom for the purposes of the Public Offers of Securities Regulations 1995,
(b) it will comply with all applicable provisions of the Financial Services Act
1986 of Great Britain with respect to anything done by it in relation to the
Securities in, from or otherwise involving the United Kingdom and (c) it will
only issue or pass on in the United Kingdom any document in connection with the
issue of the Securities to a person who is of a kind described in Article 8 of
the Financial Services Act 1986 (Investment Advertisements) (Exemptions) (No.
2) Order 1995 of Great Britian or is a person to whom the document may
otherwise lawfully be issued or passed on.

         Each series of Securities will be a new issue with no established
trading market.  Any underwriters to whom Securities are sold by the Company
for public offering and sale may make a market in such Securities, but such
underwriters will not be obligated to do so and may discontinue any market
making at any time without notice.  No assurance can be given as to the
liquidity of the trading market for any Securities.

<PAGE>   24
         Agents, dealers, and underwriters may be entitled under agreements
entered into with the Company to indemnification by the Company against certain
civil liabilities, including liabilities under the Securities Act, or to
contribution with respect to payments that such agents, dealers, or
underwriters may be required to make with respect thereto.  Underwriters,
dealers, or agents and their associates may be customers of, engage in
transactions with and perform services for, the Company in the ordinary course
of business.

                 Legg Mason Wood Walker, a member of the National Association
of Securities Dealers, Inc. (the "NASD") and an affiliate of the Company, may
participate in distributions of the Securities.  Accordingly, each offering of
Debt Securities and any market-making activities by Legg Mason Wood Walker with
respect to Securities will be conducted in compliance with the requirements of
Schedule E of the By-Laws of the NASD regarding a NASD member firm's
distributing the securities of an affiliate.  Following the initial
distribution of any Securities, Legg Mason Wood Walker may offer and sell Debt
Securities in the course of its business as a broker-dealer.  Legg Mason Wood
Walker may act as principal or agent in such transactions.  This Prospectus may
be used by Legg Mason Wood Walker in connection with such transactions.  Such
sales, if any, will be made at varying prices related to prevailing market
prices at the time of sale or otherwise.  Legg Mason Wood Walker is not
obligated to make a market in any Securities and may discontinue any
market-making activities at any time without notice.

                                 LEGAL MATTERS

the Company by Rogers & Wells, New York, New York, and certain legal matters

ITEM 15.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Registrant's By-laws provide for indemnification of any person who
is serving or has served as a director or officer of the Registrant, against
all liabilities and expenses incurred in connection with any action, suit or
proceeding arising out of such service to the full extent permitted under
Maryland law.

         Section 2-418 of the Maryland General Corporation Law establishes
provisions whereby a Maryland corporation may indemnify any director or officer
made a party to an action or proceeding by reason of service in that capacity,
against judgments, penalties, fines, settlements and reasonable expenses
incurred in connection with such action or proceeding unless it is proved that
the director or officer (i) acted in bad faith or with active and deliberate
dishonesty, (ii) actually received an improper personal benefit in money,
property or services or (iii) in the case of a criminal proceeding, had
reasonable cause to believe that his act was unlawful.  However, if the
proceeding is a derivative suit in favor of the corporation, indemnification
may not be made if the individual is adjudged to be liable to the corporation.
In no case may indemnification be made until a determination has been reached
that the director or officer has met the applicable standard of conduct.
Indemnification for reasonable expenses is mandatory if the director or officer
has been successful on the merits or otherwise in the defense of any action or
proceeding covered by the indemnification statute.  The statute also provides
for indemnification of directors and officers by court order.  The
indemnification provided or authorized in the indemnification statute does not
preclude a corporation from extending other rights (indemnification or
otherwise) to directors and officers.

         The Registrant's officers and directors are insured against certain
liabilities under a policy maintained by the Registrant with aggregate coverage
of $10,000,000.

ITEM 17.  UNDERTAKINGS

         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; (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





                                     II-2
<PAGE>   27
registration statement; (iii) To include any material information with respect
to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
if the registration statement is on Form S-3 or Form S-8, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to section 13 or section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the registration statement;

         (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes that (i) for purposes of
determining any liability under the Securities Act of 1933, 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
Securities Act shall be deemed to be part of this registration statement as of
the time it was declared effective and (ii) for the purpose of determining any
liability under the Securities Act of 1933, 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.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions set forth in Item 15, 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 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.

SECTION 1.4  Acts of Holders.

            (a)  Any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing. If Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given or taken by Holders of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article XIII, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or
record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
and so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent or proxy, or of the holding by any
Person of a Security, shall be sufficient for any purpose of this Indenture and
(subject to Section 6.1) conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Section. The record of any meeting of
Holders of Securities shall be proved in the manner provided in Section 13.6.

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

            (c)  The principal amount and serial numbers of Registered
Securities held by any Person, and the date of holding the same, shall be
proved by the Security Register.

            (d)  The principal amount and serial numbers of Bearer Securities
held by any Person, and the date of holding the same, may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be





                                       10
<PAGE>   19
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

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

            (f)  With respect to the Securities of any Series, upon receipt by
the Trustee of (i) any written notice directing the time, method or place of
conducting any proceeding or exercising any trust or power pursuant to Section
5.12 with respect to Securities of such series or (ii) any written demand,
request or notice with respect to any matter on which the Holders of Securities
of such series are entitled to act under this Indenture, in each case from
Holders of less than, or proxies representing less than, the requisite
principal amount of Outstanding Securities or such series entitled to give such
demand, request or notice, the Trustee shall establish a record date for
determining Holders of Outstanding Securities of such series entitled to join
in such demand, request or notice, which record date shall be the close of
business on the day the Trustee received such demand, request or notice. The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such demand, request or notice whether or
not such Holders remain Holders after such record date; provided, however, that
unless the Holders of the requisite principal amount of Outstanding Securities
of such series shall have joined in such demand, request or notice prior to the
day which is the ninetieth day after such record date, such demand, request or
notice shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or
a proxy of a Holder, from giving, (i) after the expiration of such 90-day
period, a new demand, request or notice identical to a demand, request or
notice which has been canceled pursuant to the proviso to the preceding
sentence or (ii) during any such 90-day period, a new demand, request or notice
which has been canceled pursuant to the proviso to the preceding sentence or
(iii) during any such 90-day period, a new demand, request or notice contrary
to or different from such demand, request or notice, in either of which events
a new record date shall be established pursuant to the provisions of this
clause.

            (g)  The Company may set any day as the record date for the purpose
of determining the Holders of Outstanding Securities of any series entitled to
give or take any request, demand,





                                       11
<PAGE>   20
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Indenture to be given or taken by Holders of Securities of
such series. With regard to any record date set pursuant to this paragraph, the
Holders of Outstanding Securities of the relevant series on such record date
(or their duly appointed agents), and only such Persons, shall be entitled to
give or take the relevant action, whether or not such Holders remain Holders
after such record date. With regard to any action that may be given or taken
hereunder only by Holders of a requisite principal amount of Outstanding
Securities of any series (or their duly appointed agents) and for which a
record date is set pursuant to this paragraph, the Company may, at its option,
set an expiration date after which no such action purported to be given or
taken by any Holder shall be effective hereunder unless given or taken on or
prior to such expiration date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents). On or prior to any expiration date set pursuant to this
paragraph, the Company may, on one or more occasions at its option, extend such
date to any later date. Nothing in this paragraph shall prevent any Holder (or
any duly appointed agent thereof) from giving or taking, after any expiration
date, any action identical to, or, at any time, contrary to or different from,
any action given or taken, or purported to have been given or taken, hereunder
by a Holder on or prior to such date, in which event the Company may set a
record date in respect thereof pursuant to this paragraph. Notwithstanding the
foregoing or the Trust Indenture Act, the Company shall not set a record date
for, and the provisions of this paragraph shall not apply with respect to, any
action to be given or taken by Holders pursuant to Section 5.1, 5.2 or 5.12.

SECTION 1.5  Notices, Etc., to Trustee and Company.

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

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

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

SECTION 1.6  Notice to Holders of Securities; Waiver.

            Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event:

                  (1)  such notice shall be sufficiently given to Holders of
                  Registered Securities if in writing and mailed, first-class
                  postage prepaid, to each Holder of a Registered Security
                  affected by such event, at the address of such Holder as it
                  appears in the Security Register, not earlier than the
                  earliest date, and not later than the latest date, prescribed
                  for the giving of such notice; and

                  (2)  such notice shall be sufficiently given to Holders of
                  Bearer Securities if published in an Authorized Newspaper in
                  The City of New York, The City of London and in such other
                  city or cities as may be specified in such Securities on a
                  Business Day at least twice, the first such publication to be
                  not earlier than the earliest date, and not later than the
                  latest date, prescribed for the giving of such notice.

            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 to
Holders of Registered Securities by mail, then such notification as shall be
made with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. In any case where notice to Holders
of Registered Securities is given by mail, neither the failure to mail such
notice, nor any defect in any notice mailed to any particular Holder of a
Registered Security shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein.

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

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


SECTION 1.7  Language of Notices, Etc.





                                       13
<PAGE>   22
            Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of
the country of publication.

SECTION 1.8  Conflict with Trust Indenture Act.

            If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by, or with another provision
(an "incorporated provision") included in this Indenture by operation of
Sections 310 to 318, inclusive, of the Trust Indenture Act, such imposed duties
of incorporated provision shall control.

SECTION 1.9  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 1.10  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 1.11  Separability Clause.

            In case any provision in this Indenture or the Securities or
Coupons 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 1.12  Benefits of Indenture.

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

SECTION 1.13  Governing Law.

            This Indenture and the Securities and Coupons shall be governed by
and construed in accordance with the laws of the State of New York without
regard to conflicts of laws.

SECTION 1.14  Legal Holidays.





                                       14
<PAGE>   23
            In any case where any Interest Payment Date, Redemption Date,
sinking fund payment date, Maturity or Stated Maturity of any Security shall
not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities or Coupons other than a
provision in the Securities of any series which specifically states that such
provision shall apply in lieu of this Section) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity, provided that no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be, to such
succeeding Business Day.

SECTION 1.15  Judgment Currency.

            The Company agrees, to the fullest extent that it may effectively
do so under applicable law, that (a) if for the purpose of obtaining judgment
in any court it is necessary to convert the sum due on the Securities of any
series from the currency in which such sum is payable in accordance with the
terms of such Securities (the "Required Currency") into a currency in which a
judgment will be rendered (the "Judgment Currency"), the rate of exchange used
shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the New York Banking Day preceding that on which a final
unappealable judgment is rendered and (b) its obligations under this Indenture
to make payments in the Required Currency (i) shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture.  For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or required by law or executive order to
close.

SECTION 1.16      Immunity of Incorporators, Shareholders, Officers, Directors
                  and Employees.

            No recourse under or upon any obligation, covenant or agreement of
this Indenture, or of any Security, or for any claim based thereon or otherwise
in respect thereof, shall be had against any incorporator, shareholder,
officer, director or employee, as such, past, present or future, of the Company
or of any successor corporation, either directly or through the Company,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of





                                       15
<PAGE>   24
any assessment or penalty or otherwise; it being expressly understood that this
Indenture and the obligations issued hereunder are solely corporate obligations
of the Company, and that no such personal liability whatever shall attach to,
or is or shall be incurred by, the incorporators, shareholders, officers,
directors or employees, as such, of the Company or of any successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations or agreements contained in
this Indenture or in any of the Securities or implied therefrom; and that any
and all such personal liability, either at common law or in equity or by
constitution or statute, of, and any and all such rights and claims against,
every such incorporator, shareholder, officer, director or employee, as such,
because of the creation of the indebtedness hereby authorized, or under of by
reason of the obligations or agreements contained in this Indenture or in any
of the Securities or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issue of such Securities.

            All payments of interest and other amounts, if any, to be made by
the Trustee hereunder shall be made only from the money deposited with the
Trustee and only to the extent that the Trustee shall have sufficient income or
proceeds to make such payments in accordance with the terms of this Indenture,
and each holder hereof, by its acceptance of a Security, agrees that it will
look solely to the income and proceeds deposited with the Trustee to the extent
available for distribution to the holder hereof as provided and that the
Trustee is not personally liable in any manner to the holder hereof for any
amounts payable or any liability under this Indenture or any Security.



                                   ARTICLE II

                                 SECURITY FORMS

SECTION 2.1  Forms Generally.

            The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related Coupons shall be in such form
(including temporary or permanent global form) as shall be established by or
pursuant to a Board Resolution or in one or more indentures supplemental
hereto, in each case with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture, and may
have such letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such Securities or Coupons, as evidenced by their execution
of the Securities or Coupons. If temporary Securities of any series are issued
in global form as permitted by Section 3.4, the form thereof shall be
established as provided in the preceding sentence. If the forms of Securities
or Coupons of any series (or any such temporary global Security) are
established by action taken pursuant to a Board Resolution, a copy of an
appropriate record of such action shall be certified by the





                                       16
<PAGE>   25
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Company Order contemplated by Section 3.3 for the
authentication and delivery of such Securities (or any such temporary global
Security) or Coupons.

            Unless otherwise specified as contemplated by Section 3.1, Bearer
Securities shall have interest Coupons attached.

            The definitive Securities and Coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities or
Coupons, as evidenced by their execution of such Securities or Coupons.

SECTION 2.2  Form of Trustee's Certificate of Authentication.

            The Trustee's certificates of authentication shall be in

                                        As Trustee

                                        By
                                        Authorized Signatory


SECTION 2.3  Securities in Global Form.

            If Securities of a series are issuable in global form, as specified
as contemplated by Section 3.1, then, notwithstanding clause (12) of Section
3.1 and the provisions of Section 3.2, any such Security shall represent such
of the Outstanding Securities of such series as shall be specified therein and
may provide that it shall represent the aggregate amount of Outstanding
Securities from time to time endorsed thereon and that the aggregate amount of
Outstanding Securities represented thereby may from time to time be reduced to
reflect exchanges. Any endorsement of a Security in global form to reflect the
amount, or any increase or decrease in the amount, of Outstanding Securities
represented thereby shall be made by the Trustee in such manner and upon
instructions given by such Person or Persons as shall be specified therein or
in the Company Order to be delivered to the Trustee pursuant to Section 3.3 or
Section 3.4. Subject to the provisions of Section 3.3 and, if appli cable,
Section 3.4, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 3.3 or 3.4 has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or





                                       17
<PAGE>   26
redelivery of a Security in global form shall be in writing but need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel.

            The provisions of the last sentence of Section 3.3 shall apply to
any Security represented by a Security in global form if such Security was
never issued and sold by the Company and the Company delivers to the Trustee
the Security in global form together with written instructions (which need not
comply with Section 1.2 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 3.3.

            Notwithstanding the provisions of Sections 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of and
any premium and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein.

            Notwithstanding the provisions of Section 3.8 and except as
provided in the preceding paragraph, the Company, the Trustee and any agent of
the Company and the Trustee shall treat a Person as the Holder of such
principal amount of Outstanding Securities represented by a permanent global
Security as shall be specified in a written statement of the Holder of such
permanent global Security or, in the case of a permanent global Security in
bearer form, of Euroclear or Cedel S.A. which is provided to the Trustee by
such Person.

SECTION 2.4  Form of Legend for Book-Entry Securities.

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

            "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee
only in the limited circumstances described in the Indenture, and no transfer
of this Security (other than a transfer of this Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except
in such limited circumstances."

SECTION 2.5  Form of Conversion Notice.

            The form of conversion notice for the conversion of Securities into
shares of Common Stock or other securities of the Company shall be in
substantially the form included with the applicable form of Securities as shall
be established pursuant to Section 2.1 hereinabove.

                                 THE SECURITIES

SECTION 3.1  Amount Unlimited; Issuable in Series.

            The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is unlimited.

            The Securities may be issued in one or more series. There shall be
established in or pursuant to a Board Resolution and, subject to Section 3.3,
set forth, or determined in the manner provided, in an Officers' Certificate,
or established in one or more indentures supplemental hereto, prior to the
issuance of Securities of any series:

                  (1)  the title of the Securities of the series (which shall
                  distinguish the Securities of the series from all other
                  series of Securities);

                  (2)  any limit upon the aggregate principal amount of the
                  Securities of the series which may be authenticated and
                  delivered under this Indenture (except for Securities
                  authenticated and delivered upon registration of transfer of,
                  or in exchange for, or in lieu of, other Securities of the
                  series pursuant to Section 3.4, 3.5, 3.6, 9.6 or 11.7 and
                  except for any Securities which, pursuant to Section 3.3, are
                  deemed never to have been authenticated and delivered
                  hereunder);

                  (3)  whether Securities of the series are to be issuable as

                  Maturity thereof pursuant to Section 5.2;

                  (17)  the Person who shall be the Security Registrar, if

                  such Depository or its nominee, if other than as set forth in
                  Section 3.5;

                  (19)  if the provisions of Section 4.4 or 4.5 are applicable
                  to the Securities of such series;

                  (20)  provisions, if any, granting special rights to the
                  Holders of Securities of the series upon the occurrence of
                  such events as may be specified;

                  (21)  any deletions from, modifications of or additions to
                  the Events of Default or covenants of the Company with
                  respect to Securities of the series, whether or not





                                       21
<PAGE>   30
                  such Events of Default or covenants are consistent with the
                  Events of Default or covenants set forth herein;

                  (22)  whether and under what conditions additional amounts
                  will be payable to Holders of Securities of the series
                  pursuant to Section 10.4; and

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

            All Securities of any one series and the Coupons appertaining to
any Bearer Securities of such series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 3.3) set forth in, or determined in the manner provided
in, the Officers' Certificate referred to above or in any such indenture
supplemental hereto.  Not all Securities of any one series need be issued at
the same time, and, unless otherwise provided, a series may be reopened for
issuances of additional Securities of such series.

            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 of the Company and delivered to the Trustee
at or prior to the delivery of the Officers' Certificate setting forth the
terms, or the manner of determining the terms, of the series.

SECTION 3.2  Denominations.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to any series of Securities, any Registered Securities of a series
shall be issuable in denominations of $1,000 and any integral multiple thereof
and any Bearer Securities of a series shall be issuable in the denomination of
$5,000.



SECTION 3.3  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 President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secre taries. The signature of any of
these officers on the Securities may be manual or facsimile. Coupons shall bear
the facsimile signature of the Treasurer of the Company.

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





                                       22
<PAGE>   31
tication 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, together
with any Coupons appertaining thereto executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided,
further, that a Bearer Security may be delivered in connection with its
original issuance only if the Person entitled to receive such Bearer Security
shall have furnished a certificate in the form specified in such Security as to
certain tax matters in respect of United States citizens, dated no earlier than
15 days prior to the earlier of the date on which such Bearer Security is
delivered and the date on which any temporary global Security first becomes
exchangeable for such Bearer Security in accordance with the terms of such
temporary global Security and this Indenture. If any Security shall be
represented by a permanent global Bearer Security, then, for purposes of this
Section and Section 3.4, the notation of a beneficial owner's interest therein
upon original issuance of such Security or upon exchange of a portion of a
temporary global Security shall be deemed to be delivery in connection with its
original issuance of such beneficial owner's interest in such permanent global
Security. Except as permitted by Section 3.6, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant Coupons for
interest then matured have been detached and cancelled.

            If all the Securities of any series are not to be issued at one
time and if the Board Resolution and indenture supplement establishing such
series shall so permit, such Company Order may set forth procedures acceptable
to the Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate, maturity date,
date of issuance and date from which interest shall accrue.

            If the forms or terms of the Securities of the series and any
related Coupons have been established in or pursuant to one or more Board
Resolutions as permitted by Sections 2.1 and 3.1, 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 6.1) shall be fully protected in relying upon, an Opinion
of Counsel stating:

                  (a)  that such forms have been established in conformity with
                  the provisions of this Indenture;

                  (b)  that such terms, or the manner of determining such
                  terms, have been established in conformity with the
                  provisions of this Indenture;

                  (c)  that such Securities, together with any Coupons
                  appertaining thereto, when authenticated and delivered by the
                  Trustee and issued by the Company in the man-





                                       23
<PAGE>   32
                  ner 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, as to enforcement, to bankruptcy,
                  insolvency, reorganization and other laws of general
                  applicability relating to or affecting the enforcement of
                  creditors' rights and to general equity principles; and

                  (d)  that all applicable laws and requirements in respect of
                  the execution and delivery by the Company of such Securities
                  have been complied with.

            If such forms or terms have been so established, the Trustee shall
not be required to authenticate such Securities if the issue or 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 3.1 and of the two
preceding paragraphs, 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 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraphs at
or prior to the time of 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 Registered Security shall be dated the date of its
authentication; and each Bearer Security shall be dated as of the date of
original issuance of the first Security of such series to be issued.

            No Security or Coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security, or the Security to which such Coupon appertains, 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 3.9 together with a written
statement (which need not comply with Section 1.2 and need not be accompanied
by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never
be entitled to the benefits of this Indenture.

SECTION 3.4  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





                                       24
<PAGE>   33
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities in lieu of which they are issued, in registered form or,
if authorized, in bearer form with one or more Coupons or without Coupons, and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities or Coupons may determine, as
evidenced by their execution of such Securities or Coupons. In the case of any
series issuable as Bearer Securities, such temporary Securities may be in
global form. A temporary Bearer Security shall be delivered only in compliance
with the conditions set forth in Section 3.3.

            Except in the case of temporary Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), 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 maintained pursuant to Section
10.2 in a Place of Payment for such series for the purpose of exchanges of
Securities of such series, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities of any series (accompanied
by any unmatured Coupons appertaining thereto) the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like
aggregate principal amount of definitive Securities of the same series and of
like tenor of authorized denominations; provided, however, that no definitive
Bearer Security shall be delivered in exchange for a temporary Registered
Security.

            If temporary Securities of any series are issued in global form,
any such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the
"Common Depositary"), for the benefit of Euroclear and Cedel S.A., for credit
to the respective accounts of the beneficial owners of such Securities (or to
such other accounts as they may direct).

            Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities of that series, in aggregate principal amount equal to
the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Secu rity shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities of such series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of
such temporary global Security to be exchanged; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation
by the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by
Euroclear as to the portion of such tempo-





                                       25
<PAGE>   34
rary global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by Cedel
S.A. as to the portion of such temporary global Security held for its account
then to be exchanged, each in the form or in such form as shall be specified in
such Security. The definitive Securities to be delivered in exchange for any
such temporary global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any
combination thereof, as specified as contemplated by Section 3.1, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof; provided, however, that definitive Bearer Securities shall be
delivered in exchange for a portion of a temporary global Security only in
compliance with the requirements of Section 3.3.

            Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or Cedel S.A., as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Cedel S.A., as the case may be, a
certificate in such form as shall be specified in such Security, dated no
earlier than 15 days prior to the Exchange Date, copies of which certificate
shall be available from the offices of Euroclear and Cedel S.A., the Trustee,
any Authenticating Agent appointed for such series of Securities and each
Paying Agent. Unless otherwise specified in such temporary global Security, any
such exchange shall be made free of charge to the beneficial owners of such
temporary global Security, except that a Person receiving definitive Securities
must bear the cost of insurance, postage, transportation and the like in the
event that such Person does not take delivery of such definitive Securities in
person at the offices of Euroclear or Cedel S.A. Definitive Securities in
bearer form to be delivered in exchange for any portion of a temporary global
Security shall be delivered only outside the United States.

            Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 3.1, interest payable on a temporary
global Security on an Interest Payment Date for Securities of such series
occurring prior to the applicable Exchange Date shall be payable to Euroclear
and Cedel S.A. on such Interest Payment Date upon delivery by Euroclear and
Cedel S.A. to the Trustee of a certificate or certificates in such form as
shall be specified in such Security, for credit with out further interest on or
after such Interest Payment Date to the respective accounts of the Persons who
are the beneficial owners of such temporary global Security on such Interest
Payment Date and who have each delivered to Euroclear or Cedel S.A., as the
case may be, a certificate in such form as shall be specified in such Security.
Any interest so received by Euroclear and Cedel S.A. and not paid as herein
provided shall be returned to the Trustee immediately prior to the expiration
of two years after such Interest Payment Date in order to be repaid to the
Company in accordance with Section 10.3.

SECTION 3.5  Registration, Registration of Transfer and Exchange.





                                       26
<PAGE>   35
            The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with Section 10.2 a register (the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Registered
Securities and the registration of transfers of Registered Securities. The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein
provided.

            Upon due surrender for registration of transfer of any Registered
Security of any series at the office or agency of the Company maintained
pursuant to Section 10.2 for such purpose in a Place of Payment for such
series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Registered Securities of the same series of any authorized denominations
and of a like aggregate principal amount and tenor.

            At the option of the Holder, Registered Securities of any series
may be exchanged for other Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at any 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. Registered Securities
may not be exchanged for Bearer Securities.

            At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured Coupons, and all matured Coupons in default
appertaining thereto. If the Holder of a Bearer Security is unable to produce
any such unmatured Coupon or Coupons or matured Coupon or Coupons in default,
such exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company in an amount equal to the face
amount of such missing Coupon or Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there is
furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such
Securities shall surrender to any Paying Agent any such missing Coupon in
respect of which such a payment shall have been made, such Holder shall be
entitled to receive the amount of such payment; provided, however, that, except
as otherwise provided in Section 10.2, interest represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an office or
agency located outside the United States. Notwithstanding the foregoing, in
case a Bearer Security of any series is surrendered at any such office or
agency in exchange for a Registered Security of the same series and like tenor
after the close of business at such office or agency on (i) any Regular Record
Date and before the opening of business at such office or agency on the
relevant Interest Payment Date, or (ii) any Special Record Date and before the
opening of business at such office or agency on the related proposed date for
payment of Defaulted Interest, such Bearer Security shall be surrendered
without the Coupon relating to





                                       27
<PAGE>   36
such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

            Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

            Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.1, any permanent global Security shall be
exchangeable only as provided in this paragraph. If the beneficial owners of
interests in a permanent global Security are entitled to exchange such
interests for Securities of such series and of like tenor and principal amount
of another authorized form and denomination, as specified as contemplated by
Section 3.1, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate
principal amount equal to the principal amount of such permanent global
Security, executed by the Company. On or after the earliest date on which such
interests may be so exchanged, such permanent global Security shall be
surrendered by the Common Depositary or such other depositary or Common
Depositary as shall be specified in the Company Order with respect thereto to
the Trustee, as the Company's agent for such purpose, to be exchanged, in whole
or from time to time in part, for definitive Securities of such series without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such permanent global Security, a like aggregate principal amount of
definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such permanent global Security to be exchanged
which, unless the Securities of the series are not issuable both as Bearer
Securities and as Registered Securities, as specified as contemplated by
Section 3.1, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof; provided, however, that no Bearer Security delivered in exchange
for a portion of a permanent global Security shall be mailed or otherwise
delivered to any location in the United States. If a Registered Security is
issued in exchange for any portion of a permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent global Security is payable in accordance with the provisions
of this Indenture.





                                       28
<PAGE>   37
            All Securities issued upon any registration of transfer or exchange
of Securities shall be the valid obligations of the Company, evidencing the
same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

            The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before any selection of Securities of that
series to be redeemed and ending at the close of business on (A) if Securities
of the series are issuable only as Registered Securities, the day of the
mailing of the relevant notice of redemption and (B) if Securities of the
series are issuable as Bearer Securities, the day of the first publication of
the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, (ii) to register the transfer of or exchange
any Registered Security so selected for redemption, in whole or in part, except
the unredeemed portion of any Security being redeemed in part, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption.

            Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 3.1, any Book-Entry Security shall be exchangeable
pursuant to this Section 3.5 or Sections 3.4, 9.6 and 11.7 for Securities
registered in the name of, and a transfer of a Book-Entry Security or any
series may be registered to, any Person other than the Depository for such
Security or its nominee only if (i) such Depository notifies the Company that
it is unwilling or unable to continue as Depository for such Book-Entry
Security or if at any time such Depository ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended, (ii) the
Company executes and delivers to the Trustee a Company Order that such
Book-Entry Security shall be so exchangeable and the transfer thereof so
registerable or (iii) there shall have occurred and be continuing an Event of
Default, or an event which after notice or lapse of time would be an Event of
Default, with respect to the Securities of such series. Upon the occurrence in
respect of any Book-Entry Security of any series of any one or more of the
conditions specified in clauses (i), (ii) or (iii) or the preced-





                                       29
<PAGE>   38
ing sentence or such other conditions as may be specified as contemplated by
Section 3.1 for such series, such Book-Entry Security may be exchanged for
Securities registered in the names of, and the transfer of such Book-Entry
Security may be registered to, such Persons (including Persons other than the
Depository with respect to such series and its nominees) as such Depository
shall direct. Notwithstanding any other provision of this Indenture, any
Security authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, any Book-Entry Security shall also be a Book-Entry
Security and shall bear the legend specified in Section 2.4 except for any
Security authenticated and delivered in exchange for, or upon registration of
transfer of, Book-Entry Security pursuant to the preceding sentence.

                  Notwithstanding anything in this Indenture or in the terms of
a Security to the contrary, the exchange of Bearer Securities for Registered
Securities will be subject to satisfaction of the provisions of the United
States Federal income tax laws in effect at the time of such exchange.  None of
the Company, the Trustee or any Authenticating Agent of the Company or the
Trustee (any of which, other than the Company, shall rely on an Officers'
Certificate and an Opinion of Counsel) shall be required to exchange any Bearer
Security for a Registered Security if as a result thereof and in the Company's
reasonable judgment, the Company would incur adverse consequences under then
applicable United States Federal income tax laws.

SECTION 3.6  Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

            If any mutilated Security or a Security with a mutilated Coupon
appertaining thereto 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, with Coupons corresponding to the
Coupons, if any, appertaining to the surrendered Security and such mutilated
Security or a Security with a mutilated Coupon, if any, shall be cancelled by
the Trustee in accordance with the Indenture.

            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 or Coupon and (ii) such security or in demnity as may be required by
them, then, in the absence of notice to the Company or the Trustee that such
Security or Coupon has been acquired by a bona fide purchaser, the Company
shall, subject to the following paragraph, execute, and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
Coupon appertains (with all appurtenant Coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with Coupons corresponding
to the Coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen Coupon appertains.





                                       30
<PAGE>   39
            In case any such mutilated, destroyed, lost or stolen Security or
Coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security or Coupon;
provided, however, that principal of and any premium and interest on Bearer
Securities shall, except as otherwise provided in Section 10.2, be payable only
at an office or agency located outside the United States.

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

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

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


SECTION 3.7  Payment of Interest; Interest Rights Preserved.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to any series of Securities, interest on any Registered 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; provided, however, that each installment
of interest on any Registered Security may at the Company's option be paid by
(i) mailing a check for such interest, payable to or upon the written order of
the Person entitled thereto pursuant to Section 3.8, to the address of such
Person as it appears on the Security Register or (ii) transfer to an account
maintained by the payee located inside the United States.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to the Securities of any series, payment of interest may be made, in
the case of a Bearer Security, by transfer to an account maintained by the
payee with a bank located outside the United States.

            Unless otherwise provided as contemplated by Section 3.1, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such





                                       31
<PAGE>   40
permanent global Security held for its account by Cede & Co. or the Common
Depositary, as the case may be, for the purpose of permitting such party to
credit the interest received by it in respect of such permanent global Security
to the accounts of the beneficial owners thereof.

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

            Any interest on any Registered 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) and (2) below:

                  (1)  The Company may elect to make payment of any Defaulted
                  Interest to the Persons in whose names the Registered
                  Securities of such series (or their respective Predecessor
                  Securities) are registered at the close of business on a
                  Special Record Date for the payment of such Defaulted
                  Interest, which shall be fixed in the following manner. The
                  Company shall notify the Trustee in writing of the amount of
                  Defaulted Interest proposed to be paid on each Registered
                  Security of such series and the date of the proposed payment,
                  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 mailed, first-class postage
                  prepaid, to each Holder of Registered Securities of such
                  series at the address of such Holder as it appears in the
                  Security Register, not less than 10 days prior to such
                  Special Record Date. Notice of the proposed payment of such
                  Defaulted Interest and the Special Record Date therefor
                  having been so mailed, such Defaulted Interest shall be paid
                  to the Persons in whose names the Registered Securities of
                  such series (or their respective Predecessor Securities) are
                  registered





                                       32
<PAGE>   41
                  at the close of business on such Special Record Date and
                  shall no longer be payable pursuant to the following Clause
                  (2); and

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

            Subject to the foregoing provisions of this Section and Section
3.5, 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.

            In the case of any Security which is converted into Common Stock of
the Company after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security whose Maturity is
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 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 preced ing sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of
such Security shall not be payable.

SECTION 3.8  Persons Deemed Owners.

            Prior to due presentment of a Registered Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Registered Security for the purpose of
receiving payment of principal of (and premium, if any) and (subject to
Sections 3.5 and 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security shall 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.

            Title to any Bearer Security and any Coupons appertaining thereto
shall pass by delivery. The Company, the Trustee and any agent of the Company
or the Trustee may treat the bearer of any Bearer Security and the Bearer of
any Coupon as the absolute owner of such Security or Coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or Coupon shall 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.





                                       33
<PAGE>   42
            Except as provided in Section 3.5, owners of beneficial interests
in a Global Security shall not be entitled to have Securities represented by
such Global Security registered in their names, shall not receive or be
entitled to receive physical delivery of Securities in certificated form and
shall not be considered the Holders thereof for any purpose under this
Indenture.  Members or participants in the Depository shall have no rights
under this Indenture with respect to any Global Security held on their behalf
by the Depository, and such Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the Holder of such
Global Security under this Indenture.  Notwithstanding the foregoing, with
respect to any Global Security,  nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by the
Depository, as a Holder, with respect to such Global Security or impair, as
between the Depository and owners of beneficial interests in such Global
Security, the operation of customary practices governing the exercise of the
rights of the Depository (or its nominee) as Holder of such Global Security.

            None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests or for the delivery to
any member of or participants in the Depository of any notice permitted or
required to be given to the Holders of the Securities under this Indenture.

SECTION 3.9  Cancellation.

            All Securities and Coupons 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. All Registered Securities and matured Coupons so
delivered shall be promptly cancelled by the Trustee. All Bearer Securities and
unmatured Coupons so delivered shall be cancelled. All Bearer Securities and
unmatured Coupons held by the Trustee pending such cancellation or reissuance
shall be deemed to be delivered for cancellation for all purposes of this
Indenture and the Securities. 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 cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities and
Coupons held by the Trustee shall be disposed of as directed by a Company
Order, or in the absence of a Company Order, may be destroyed by the Trustee;
provided, however, that the Trustee shall not be required to destroy such
cancelled Securities.

            Notwithstanding the foregoing, with respect to any Book-Entry
Security, nothing herein shall prevent the Company, the Trustee or any agent of
the Company or the Trustee, from





                                       34
<PAGE>   43
giving effect to any written certification, proxy or other authorization
furnished by a Depository or impair, as between a Depository and holders of
beneficial interests in any Book-Entry Security, the operation of customary
practices governing the exercise of the rights of the Depositary (or its
nominee) as Holder of such Book-Entry Security.

SECTION 3.10  Computation of Interest.

            Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.11  Electronic Security Issuance.

            The Securities may, pursuant to a Board Resolution and Officers'
Certificate complying with Section 3.1 hereof, be issued by means of an
electronic issuance system. Any such Security issuance instructions may specify
the name, address and taxpayer identification number of the Holder, the
principal amount and Maturity of the Security, the interest rate to be borne by
the Security and any other terms not inconsistent with such Board Resolution
and Officers' Certificate. Nothing in this Section 3.11 shall be construed as
prohibiting the Company from issuing Securities by any means not inconsistent
with the provisions of this Indenture.

SECTION 3.12  CUSIP Numbers.

            The Company in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be
affected by any defect in or omission of such numbers.  The Company will
promptly notify the Trustee of any change in the CUSIP numbers.


                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

SECTION 4.1  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 any right to receive
additional amounts, as provided in Section 10.4), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when:





                                       35
<PAGE>   44
                  (1) either

determine, to the Persons entitled thereto, of the principal (and premium, if
any) and any interest for whose payment such money and U.S. Government
Obligations has been deposited with or received by the Trustee.

SECTION 4.3  Company's Option to Effect Defeasance or Covenant Defeasance.

            If applicable to a particular series of Securities, the Company may

be, designated pursuant to Section 3.1 as being defeasible pursuant to such
Section 4.4 or 4.5, in accordance with any applicable requirements provided

in another manner specified as contemplated by Section 3.1 for such Securities.

SECTION 4.4  Discharge and Defeasance.

            If this Section 4.4 is specified, as contemplated by Section 3.1,

Company shall be deemed to have paid and discharged the entire indebtedness on
all the Outstanding Securities of any such series ("Defeasance"); and (ii) the
provisions of this Indenture as it relates to such Outstanding Securities shall
no longer be in effect (except as to the rights of Holders of Securities to

SECTION 4.5  Covenant Defeasance.

            If this Section 4.5 is specified, as contemplated by Section 3.1,
to be applicable to any series of Securities or any Securities of such series,
as the case may be, (1) the Company shall be released from its obligations
under Section 8.1(3) and Sections 10.4 through 10.9, inclusive, and any
covenants provided pursuant to Section 3.1(21), 9.1(2) or 9.1(6) for the
benefit of the Holders of such Securities that pursuant to the terms of such
Securities are defeasible pursuant to this Section 4.5 and (2) the occurrence
of any event specified in Sections 5.1(4) (with respect to any of Section
8.1(3), Sections 10.4 through 10.9, inclusive, and any such covenants provided
pursuant to Section 3.1(21), 9.1(2), or 9.1(6) and 5.1(9) (if pursuant to the
terms of such Securities this Section 4.5 is applicable to any such event
specified in Section 5.1(9)) 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 4.6 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 5.1(4) and 5.1(9)), 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 4.6  Conditions to Defeasance or Covenant  Defeasance.

            The following shall be the conditions to the application of Section
4.4 or Section 4.5 to any applicable series of Securities or any Securities of
such series, as the case may be.

                  (1)  either

                  (A)  with respect to all Outstanding Securities of such
                  series or such Securities of such Series, as the case may be,
                  with reference to this Section 4.6, the Company has deposited
                  or caused to be deposited with the Trustee irrevocably (but
                  subject to the provisions of Section 4.2 and the last
                  paragraph of Section 10.3), as trust funds in trust,
                  specifically pledged as security for, and dedicated solely
                  to, the benefit of the Holders of such Securities, (X) lawful
                  money of the United States in an amount, or (Y) U.S.
                  Government Obligations which through the payment of interest
                  and principal in respect thereof in accordance with their
                  terms will provide not later than the opening of business on
                  the due dates of any payment referred to in clause (i) or
                  (ii) of this subparagraph (1)(A) lawful money of the United
                  States in an amount, or (Z) a combination thereof,
                  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 (i) the principal of (and premium, if any) and each
                  installment of principal of (and premium, if any) and
                  interest on such Securities at the Stated Maturity of such
                  principal or

                  installment of principal or interest or upon optional
                  redemption and (ii) any mandatory sinking fund payments or
                  analogous payments applicable to such Securities on the day
                  on which such payments are due and payable in accordance with
                  the terms of this Indenture and of such Securities; or

                  (B)  the Company has properly fulfilled such other means of
                  satisfaction and discharge as is specified, as contemplated
                  by Section 3.1, to be applicable to the Securities of such
                  series;

                  (2)  the Company has paid or caused to be paid all other sums
                  payable with respect to such Securities;

                  (3)  such deposit will not result in a breach or violation
                  of, or constitute a default under, this Indenture or any
                  other agreement or instrument to which the Company is a party
                  or by which it is bound;

                  (4)  no Event of Default or event which with the giving of
                  notice or lapse of time, or both, would become an Event of
                  Default with respect to such Securities shall have occurred
                  and be continuing on the date of such deposit and no Event of
                  Default under Section 5.1(5) or Section 5.1(6) or event which
                  with the giving of notice or lapse of time, or both, would
                  become an Event of Default under Section 5.1(5) or Section
                  5.1(6) shall have occurred and be continuing on the 91st day
                  after such date;

                  (5)  in the event of an election to have Section 4.4 apply to
                  any series of Securities, the Company has delivered to the
                  Trustee an Opinion of Counsel to the effect 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 Indenture there has been a change in applicable
                  Federal income tax law, in either case to the effect that,
                  and based thereon such Opinion of Counsel shall confirm that,
                  the Holders of Securities of such series will not recognize
                  income, 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 and in the
                  same manner and at the same times as would have been the case
                  if such deposit, defeasance and discharge had not occurred;

                  (6)  in the event of an election to have Section 4.5 apply to
                  any series of Securities, 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;





                                       39
<PAGE>   48
                  (7)  if the Securities of that series are then listed on any
                  domestic or foreign securities exchange, the Company shall
                  have delivered to the Trustee an Opinion of Counsel to the
                  effect that such deposit, defeasance and discharge will not
                  cause such Securities to be desisted; and

                  (8)  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
                  Defeasance or Covenant Defeasance with respect to such
                  Securities of any such series have been complied with and an
                  Opinion of Counsel to the effect that either (i) as a result
                  of such deposit and the related exercise of the Company's
                  option under this Article, registration is not required under
                  the Investment Company Act of 1940, as amended, by the
                  Company, the trust funds representing such deposit or the
                  Trustee or (ii) all necessary registrations under said Act
                  have been effected.

            Any deposits with the Trustee referred to in Section 4.6(1)(A)
above shall be irrevocable and shall be made under the terms of an escrow/trust
agreement in form and substance satisfactory to the Trustee. If any Outstanding
Securities of such series are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with
any mandatory sinking fund requirement, the applicable escrow trust agreement
shall provide therefor and the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company.

            Upon Defeasance with respect to all the Securities of a series, the
terms and conditions of such Securities, including the terms and conditions
with respect thereto set forth in this Indenture, shall no longer be binding
upon, or applicable to, the Company; provided that the Company shall not be
discharged from any payment obligations in respect of Securities which are
deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law.

            Notwithstanding the cessation, termination and discharge of all
obligations, covenants and agreements (except as provided above in this Section
4.6) of the Company under this Indenture with respect to any series of
Securities, the obligations of the Company to the Trustee under Section 6.5,
and the obligations of the Trustee under Section 4.2 and the last paragraph of
Section 10.3 shall survive with respect to such series of 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 this
Section 4.6 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.

            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 4.1 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.

                  consecutive days; or

                  ment 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

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

SECTION 5.2  Acceleration of Maturity; Rescission and Annulment.

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

            At any time after such a declaration of acceleration with respect
to Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of at least 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





                                       43
<PAGE>   52
                  solely by such declaration of acceleration, have been cured
                  or waived as provided in Section 5.13.

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

SECTION 5.3  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 of any series 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 of any series at the
                  Maturity thereof,

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

            If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities, wherever situated.

            If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series and any Coupons appertaining thereto 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 5.4  Trustee May File Proofs of Claim.

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

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

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

and any custodian, receiver, assignee, trustee, liquidation, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities and Coupons to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities and Coupons, 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 6.7.

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

SECTION 5.5  Trustee May Enforce Claims Without Possession of Securities or
             Coupons.

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





                                       45
<PAGE>   54
for the ratable benefit of the Holders of the Securities and Coupons in respect
of which such judgment has been recovered.

SECTION 5.6  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 or Coupons, or both,
as the case may be, and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
                  Section 6.7;

                  SECOND: To the payment of the amounts then due and unpaid for
                  principal of and any premium and interest on the Securities
                  and Coupons 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 and Coupons for principal and any
                  premium and interest, respectively; and
     
                  THIRD:  To the payment of the remainder, if any, to the 
                  Company.

SECTION 5.7  Limitation on Suits.

            No Holder of any Security of any series or any related Coupons
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





                                       46
<PAGE>   55
                  (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 5.8  Unconditional Right of Holders to Receive Principal, Premium and
             Interest.

            Notwithstanding any other provision in this Indenture, the Holder
of any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to Section 3.7) interest on such Security, and any additional amounts
contemplated by Section 10.4 in respect of such Security or payment of such
Coupon on the Stated Maturity or Maturities expressed in such Security or
Coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

SECTION 5.9  Restoration of Rights and Remedies.

            If the Trustee or any Holder of a Security or Coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and Coupons 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 5.10  Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or Coupons in the
last paragraph of Section 3.6, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or Coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

SECTION 5.11  Delay or Omission Not Waiver.





                                       47
<PAGE>   56
            No delay or omission of the Trustee or of any Holder of any
Security or Coupon to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given
by this Article or by law to the Trustee or to the Holders of Securities or
Coupons may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or Coupons, as the
case may be.

SECTION 5.12  Control by Holders of Securities.

            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

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

SECTION 5.13  Waiver of Past Defaults.

            The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto waive any past
default hereunder with respect to the Securities of such series and its
consequences, except a default

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

                  (2)  in respect of a covenant or provision hereof which under
                  Article IX cannot be modified or amended without the consent
                  of the Holder of each Outstanding Security of 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 5.14  Undertaking for Costs.

            All parties to this Indenture agree, and each Holder of any
Security or Coupon by his acceptance thereof shall be deemed to have agreed,
that any court may in its discretion re quire, in any suit for the enforcement
of any right or remedy under this Indenture, or in any





                                       48
<PAGE>   57
suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees and expenses, against
any party litigant in such suit, having due regard to the merits and good faith
of the claims or defenses made by such party litigant; but the provisions of
this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
of any Security or Coupon for the enforcement of the payment of the principal
of or any premium or interest on any Security or the payment of any Coupon on
or after the Stated Maturity or Maturities expressed in such Security or Coupon
(or, in the case of redemption, on or after the Redemption Date).

SECTION 5.15  Waiver of Stay or Extension Laws.

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

                                   ARTICLE VI

                                  THE TRUSTEE


SECTION 6.1  Duties and Responsibilities of the Trustee; During Default; Prior
             to Default.

            With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or
waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture.  In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived), the Trustee shall exercise with respect to such series of Securities
such of the rights and powers vested in it by this Indenture, and shall use the
same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.





                                       49
<PAGE>   58
            No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own wilful misconduct, except that:

            (a)   prior to the occurrence of an Event of Default with respect
to the Securities of any series and after the curing or waiving of all such
Events of Default with respect to such series which may have occurred:

                  (i)  the duties and obligations of the Trustee with respect
                  to the Securities of any series shall be determined solely by
                  the express provisions of this Indenture, and the Trustee
                  shall not be liable except for the performance of such duties
                  and obligations as are specifically set forth in this
                  Indenture, and no implied covenants or obligations shall be
                  read into this Indenture against the Trustee; and

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

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

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.

                                       51
<PAGE>   60
            The recitals contained herein and in the Securities (except the

the statements of the Company, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the

and perform its obligations hereunder and that the statements made by it in its
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate. The Trustee or any Authenticating Agent shall not be accountable for

            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 Coupons and,

same rights it would have if it were not Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other agent.

SECTION 6.5  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

SECTION 6.6  Compensation and Reimbursement..

            The Company agrees:

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

                  (2)  except as otherwise expressly provided herein, to
                  reimburse the Trustee or any predecessor Trustee upon its
                  request for all reasonable expenses, disbursements and
                  advances incurred or made by the Trustee in accordance with
                  any provision of this Indenture (including the 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 and any predecessor Trustee
                  for, and to hold it harmless against, any and all loss,
                  damage, claim, liability or expense, including taxes (other
                  than taxes based on the income of the Trustee) incurred
                  without negligence or bad faith on its part, arising out of
                  or in connection with the acceptance





                                       52
<PAGE>   61
                  or administration of the trust or trusts hereunder, including
                  the costs and expenses of defending itself against any claim
                  or liability in connection with the exercise or performance
                  of any of its powers or duties hereunder.

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(7) or Section 5.1(8), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

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

SECTION 6.7  Resignation and Removal; Appointment of Successor.

            (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.8.

            (b)  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.8 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.

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

            (d)  If at any time:

                  (1)  the Trustee shall fail to comply with Section 310(b) of
                  the Trust Indenture Act after written request therefor by the
                  Company or by any Holder of a Security who has been a bona
                  fide Holder of a Security for at least six months, or

                  (2)  the Trustee shall cease to be eligible under Section 6.9
                  and Section 310(a) of the Trust Indenture Act 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, (i) the
                  Company by a Board Resolution may remove the Trustee with





                                       53
<PAGE>   62
                  respect to all Securities, or (ii) subject to Section 5.14
                  any Holder of a Security who has been a bona fide Holder of a
                  Security for at least six months may, on behalf of himself
                  and all others similarly situated, petition any court of
                  competent jurisdiction for the removal of the Trustee with
                  respect to all Securities and the appointment of a successor
                  Trustee or Trustees.

            (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause,
with respect to the Securities of one or more series, the Company, by 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 6.8. 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
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 6.8, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities of
that series and accepted appointment in the manner required by Section 6.8, any
Holder of a Security who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

            (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided in Section 1.6. 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 6.8  Acceptance of Appointment by Successor.

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





                                       54
<PAGE>   63
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.

            (b)  In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such
appointment and which (l) 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 as co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

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

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

SECTION 6.9  Disqualification; Conflicting Interests.

            If the Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.





                                       55
<PAGE>   64
SECTION 6.10  Corporate Trustee Required; Eligibility.

            There shall be at all times a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000.  If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, 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 shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereunder specified in this
Article.

SECTION 6.11  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 6.12  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 6.13  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 au thenticate Securities of such series issued upon
original issue or upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 3.6, 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 accept-





                                       56
<PAGE>   65
able to the Company. 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 such 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 such 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 promptly give notice
of such appointment to all Holders of Securities pursuant to Section 1.6. 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 Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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

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


                                        The Bank of New York,
                                        As Trustee

                                        Authorized Signatory


            If all of the Securities of a series may not be originally issued
at one time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable
of authenticating Securities upon original issuance located in a Place of
Payment where the Company wishes to have Securities of such series
authenticated upon original issuance, the Trustee, if so requested by the
Company in writing (which writing need not comply with Section 1.2 and need not
be accompanied by an Opinion of Counsel), shall appoint in accordance with this
Section an Authenticating Agent (which if so requested by the Company, shall be
such Affiliate of the Company) having an office in a Place of Payment
designated by the Company with respect to such series of Securities.

SECTION 6.14.  Notice of Defaults.

            If a default occurs hereunder with respect to Securities of any
series, the Trustee shall, within 90 days of such occurrence,  give the Holders
of Securities of such series notice of such default known to it 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 5.1(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.

of a new list so furnished, (ii) destroy any information received by it as
Paying Agent (if so acting) hereunder upon delivering to itself as Trustee, not
earlier than March 20 or September 20 of each year, a list containing the names
and addresses of the Holders of Securities obtained from such information since
the delivery of the next previous list, if any, (iii) destroy any list
delivered to itself as Trustee which was compiled from information received by
it as Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered and (iv) destroy not earlier than two years after filing, any
information filed with it pursuant to Section 313(c)(2) of the Trust Indenture
Act.  For purposes of Section 312(a) of the Trust Indenture Act, the term
"stated intervals" shall mean January 15 and July 15.

            (b)  If three or more Holders of Securities (herein referred to as
"applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security for a period of
at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other Holders
of Securities with respect to their rights under this Indenture or under the
Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee
shall, within five business days after the receipt of such application, at its
election, either

                  (i)  afford such applicants access to the information
                  preserved at the time by the Trustee in accordance with
                  Section 7.1(a), or

                  (ii)  inform such applicants as to the approximate number of
                  Holders of Securities whose names and addresses appear in the
                  information preserved at the time by the Trustee in
                  accordance with Section 7.1(a), and as to the approximate
                  cost of mailing to such Holders the form of proxy or other
                  communication, if any, specified in such application.

            If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of Securities whose name and address appears in
the information preserved at the time by the Trustee in accordance with Section
7.1(a) a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment of the
reasonable expenses of mailing, unless within five days after such tender the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interest of the Holders of Securities or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in
the written statement so filed, shall enter an order refusing to sustain any of
such objections or if after the entry of an order sustaining one or more of
such objections, the Commission shall find, after notice and opportunity for
hearing that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such material to all such
Holders of Securities





                                       59
<PAGE>   68
with reasonable promptness after the entry of such order and the renewal of
such tender; otherwise the Trustee shall be relieved of any obligation or duty
to such applicants respecting their application.

            (c)  Every Holder of Securities or Coupons, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any agent of either of them shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Holders of Securities in accordance with Section 7.1(b),
regardless of the source from which such information was derived and that the
Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under Section 7.1(b).

SECTION 7.2  Reports by Trustee.

            The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto.
If required by Section 313(a) of the Trust Indenture Act, the Trustee shall,

to Holders, be filed by the Trustee with each stock exchange upon which any
Securities are listed, with the Commission and with the Company. The Company
will promptly notify the Trustee when any Securities are listed on any stock
exchange or market center.

            The Company shall:

                  (1) file with the Trustee, within 15 days after the Company
            is required to file the same with the Commission, copies of the
            annual reports and of the information, documents and other reports
            (or copies of such portions of any of the foregoing as the
            Commission may from time to time by rules and regulations
            prescribe) which the Company may be required to file with the
            Commission pursuant to Section 13 or Section 15(d) of the Exchange
            Act; or, if the Company is not required to file information,
            documents or reports pursuant to either of such Sections, then it

            rules and regulations prescribed from time to time by the
            Commission, such of the supplementary and periodic information,
            documents and reports which may be required pursuant to Section 13

                  (3)  transmit to all Holders, in the manner and to the extent
            provided in Trust Indenture Act Section 313(c), within 30 days
            after the filing thereof with the Trustee, such summaries of any

            by the Commission.

            Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's

SECTION 9.6  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 X

                                   COVENANTS

SECTION 10.1  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 or cause to be paid the
principal of and any premium and interest on the Securities of that series in
accordance with the terms of the Securities, any Coupons appertaining thereto
and this Indenture. Unless otherwise specified as contemplat ed by Section 3.1
with respect to any series of Securities, any interest due on Bearer Securities
on or before Maturity shall be payable only upon presentation and surrender
outside the United States of the several Coupons for such interest installments
as are evidenced thereby as they severally mature.

SECTION 10.2  Maintenance of Office or Agency.

            If Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for such series
an office or agency where Securities of that series may be presented or
surrendered for payment, where Securities of that series may





                                       66
<PAGE>   75
be surrendered for registration of transfer, exchange, or 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. If Securities of a series are issuable
as Bearer Securities, the Company will maintain (A) in The City of New York, an
office or agency where any Registered Securities of that series may be
presented or surrendered for payment, where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for conversion or exchange, where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served and where Bearer Securities of that series and
related Coupons may be presented or surrendered for payment in the
circumstances described in the following paragraph (and not otherwise), (B)
subject to any laws or regulations applicable thereto, in a Place of Payment
for that series which is located outside the United States, an office or agency
where Securities of that series and related Coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Securities of that series pursuant to Section 10.4); provided, however, that if
the Securities of that series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland, the Luxembourg Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange, and (C) subject to any laws or regulations applicable
thereto in a Place of Payment for that series located outside the United States
an office or agency where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may
be surrendered for conversion or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt notice to the Trustee and to the
Holders as provided in Sections 1.5 and 1.6, respectively, of the location and
any change in the location, of any such office or agency. If at any time the
Company shall fail to maintain any such required office or agency in respect of
any series of Securities or shall fail to furnish the Trustee with the address
thereof, such presentations and surrenders of Securities of that series may be
made and notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of that series and the
related Coupons may be presented and surrendered for payment (including payment
of any additional amounts payable on Bearer Securities of that series pursuant
to Section 10.4) at the office of the Trustee for such series located outside
the United States, and the Company hereby appoints the same as its agent to
receive such respective presentations, surrenders, notices and demands.

            No payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to any account
maintained with a bank located in the United States; provided, however, that if
the Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium and interest on any Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
10.4) shall be made at the office of the Company's Paying Agent in The City of
New York, if (but





                                       67
<PAGE>   76
only if) payment in Dollars of the full amount of such principal, premium,
interest or additional amounts, as the case may be, at all offices or agencies
outside the United States maintained for the purpose by the Company in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

            The Company may 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 accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to
the Trustee and the Holders of any such designation or rescission and of any
change in the location of any such other office or agency.

SECTION 10.3  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 and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure to act.

            Whenever the Company shall have one or more Paying Agents for any
series of Securities it will, prior to each due date of the principal of and
any premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay the principal and any premium or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to act.

            The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

                  (1)  hold all sums held by it for the payment of the
                  principal of and any premium or interest on Securities of
                  that series in trust for the benefit of the Persons entitled
                  thereto until such sums shall be paid to such Persons or
                  otherwise disposed of as herein provided;

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





                                       68
<PAGE>   77
                  (3)  at any time during the continuance of any such default,
                  upon the written request of the Trustee, forthwith pay to the
                  Trustee all sums so held in trust by such Paying Agent.

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such 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 and any
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal and any 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 or any Coupon appertaining thereto 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 an Authorized Newspaper 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 10.4  Additional Amounts.

            If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any Coupon appertaining thereto additional amounts as provided therein.
Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of any Security
of any series or payment of any related Coupon or the net proceeds received on
the sale or exchange of any Security of any series, such mention shall be
deemed to include mention of the payment of additional amounts provided for in
this Section to the extent that, in such context additional amounts are, were
or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of additional amounts (if
applicable) in any provisions hereof shall not be construed as excluding
additional amounts in those provisions hereof where such express mention is not
made.

            If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a





                                       69
<PAGE>   78
payment of principal and any premium is made), and at least 10 days prior to
each date of payment of principal and any premium or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Company will furnish the Trustee and the Company's
principal Paying Agent or Paying Agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and any premium or interest on the
Securities of that series shall be made to Holders of Securities of that series
or any related Coupons who are United States Aliens without withholding for or
on account of any tax assessment or other governmental charge described in the
Securities of that series. If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities or Coupons and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by this Section. The Company covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or willful misconduct on their
part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this
Section.

SECTION 10.5  Existence.

            Subject to Article VIII, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the
loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 10.6  Purchase of Securities by Company or Subsidiary.

            If and so long as the Securities of a series are listed on The
Stock Exchange of the United Kingdom and the Republic of Ireland and such stock
exchange shall so require, the Company will not, and will not permit any of its
Subsidiaries to, purchase any Securities of that series by private treaty at a
price (exclusive of expenses and accrued interest) which exceeds 120% of the
mean of the nominal quotations of the Securities of that series as shown in The
Stock Exchange Daily Official List for the last trading day preceding the date
of purchase.

SECTION 10.7  Negative Pledge.

            Neither the Company nor any successor corporation will, or will
permit any Subsidiary (as hereinafter defined) to, create, assume, incur or
guarantee any indebtedness for borrowed money secured by a pledge, lien or
other encumbrance (except for Permitted Liens, as hereinafter defined) on the
Voting Securities of Legg Mason Wood Walker, unless the Company shall cause the
Securities to be secured equally and ratably with (or, at the Company's option,
prior to) any indebtedness secured thereby.  "Subsidiary" means any
corporation, part-





                                       70
<PAGE>   79
nership or other entity of which at the time of determination the Company owns
or controls directly or indirectly more than 50% of the shares of Voting
Securities or equivalent interest.  "Permitted Liens" means liens for taxes or
assessments or governmental charges or levies not then due and delinquent or
the validity of which is being contested in good faith or which are less than
$1,000,000 in amount, liens created by or resulting from any litigation or
legal proceeding which is currently being contested in good faith by
appropriate proceedings or which involves claims of less than $1,000,000,
deposits to secure (or in lieu of) surety, stay, appeal or customs bonds and
such other liens as the Board of Directors of the Company determines do not
materially detract from or interfere with the present value or control of the
Voting Securities subject thereto or affected thereby.

SECTION 10.8  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 signed by its principal executive officer, principal
financial officer or principal accounting officer stating whether or not to the
best knowledge of the signer thereof the Company is in default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture, and if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

SECTION 10.9     Calculation of Original Issue Discount.

            The Company shall file with the Trustee promptly at the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities
as of the end of such year.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

SECTION 11.1  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 3.1 for Securities of any
series) in accordance with this Article.

SECTION 11.2  Election to Redeem; Notice to Trustee.

            The election of the Company to redeem any Securities shall be
evidenced by an Officers' Certificate. In the case of any redemption at the
election of the Company, 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 and





                                       71
<PAGE>   80
of the principal amount of Securities of such series to be redeemed. In the
case of any redemption of Securities (i) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, or (ii) pursuant to an election of the Company
which is subject to a condition specified in the terms of such Securities, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction or condition.

SECTION 11.3  Selection by Trustee of Securities to Be Redeemed.

            If less than all the Securities of any series and of like tenor are
to be redeemed, the particular Securities to be redeemed shall be selected not
more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and of like tenor not previously called
for redemption, by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection, for redemption of portions (equal to
the minimum authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Registered Securities of
such series of a denomination larger than the minimum authorized denomination
for Securities of that series. If so specified in the Securities of a series,
partial redemptions must be in an amount not less than $1,000,000 principal
amount of Securities.

            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
(or portions thereof) 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. In any case where more than one Security is
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security.

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

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any 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 11.4  Notice of Redemption.

            Notice of redemption shall be given in the manner provided in
Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor
more than 60 days prior to the Redemption Date.





                                       72
<PAGE>   81
            Any notice that is mailed to Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

            All notices of redemption shall state:

                  (1)  the Redemption Date;

                  (2)  the Redemption Price;

                  (3)  if less than all the Outstanding Securities of any
                  series are to be redeemed, the identification (and, in the
                  case of partial redemption, the principal amounts) of the
                  particular Securities to be redeemed, and a statement to the
                  effect that on or after the Redemption Date upon surrender of
                  such Security a new Security in the principal amount equal to
                  the unredeemed portion will be issued;

                  (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 such Securities, together in
                  the case of Bearer Securities with all Coupons appertaining
                  thereto, if any maturing after the Redemption Date, are to be
                  surrendered for payment of the Redemption Price;

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

                  (7)  if applicable, the conversion rate or price, the date on
                  which the right to convert the Securities to be redeemed will
                  terminate and the place or places where such Securities may
                  be surrendered for conversion.

            A notice of redemption published as contemplated by Section 1.6
need not identify particular Registered Securities to be redeemed.

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

SECTION 11.5  Deposit of Redemption Price.

            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 10.3) 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.





                                       73
<PAGE>   82
            If any Security called for redemption is converted into Common
Stock of the Company, any money deposited with the Trustee or with any Paying
Agent or so segregated and held in trust for the redemption of such Security
shall (subject to any right of the Holder of such Security or any Predecessor
Security to receive interest as provided in the last paragraph of Section 3.7)
be paid to the Company upon Company Request or, if then held by the Company,
shall be discharged from such trust.

SECTION 11.6  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 and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price together with accrued interest to
the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except
as otherwise provided in Section 10.2) and, unless otherwise specified as
contemplated by Section 3.1, only upon presentation and surrender of Coupons
for such interest; and provided, further, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 3.7.

            If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such
missing Coupon or Coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless. If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
Coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by Coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 10.2) and unless otherwise specified as contemplated by
Section 3.1 only upon presentation and surrender of those Coupons.

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





                                       74
<PAGE>   83
SECTION 11.7  Securities Redeemed in Part.

            Any Registered 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 his attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series and of like tenor of any authorized denomination as requested by
such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.



                                  ARTICLE XII

                                 SINKING FUNDS

SECTION 12.1  Applicability of Article.

            The provisions of this Article shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise specified
as contemplated by Section 3.1 for Securities of such series.

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 12.2. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 12.2  Satisfaction of Sinking Fund Payments with Securities.

            The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption), together in the case of any
Bearer Securities of such series with all unmatured Coupons appertaining
thereto, and (2) 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 the Securities
of such series required to be made pursuant to the terms of such Securities, as
provided for by the terms of such series; provided that such Securities have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the Redemption Price specified in such
Securities





                                       75

for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly.

SECTION 12.3  Redemption of Securities for Sinking Fund.

            Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 45 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 11.3 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 11.4. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in
the manner stated in Sections 11.6 and 11.7.

<PAGE>   85
            (b)  In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 25% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified
in Section 13.1, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have made
the first publication of the notice of such meeting within 21 days after
receipt of such request or shall not thereafter proceed to cause the meeting to
be held as provided herein, then the Company or the Holders of Securities of
such series in the amount above specified, as the case may be, may determine
the time and the place in the Borough of Manhattan, The City of New York or in
London for such meeting and may call such meeting for such purposes by giving
notice thereof as provided in subsection (a) of this Section.

SECTION 13.3  Persons Entitled to Vote at Meetings.

            Upon the calling of a meeting of Holders with respect to the
Securities of a series all or part of which are represented by a Book-Entry
Security, a record date shall be established for determining Holders of
Outstanding Securities of such series entitled to vote at such meeting, which
record date shall be the close of business on the day the notice of the meeting
of Holders is given in accordance with Section 13.2. The Holders on such record
date, and their designated proxies, and only such Persons, shall be entitled to
vote at any meeting of Holders. To be entitled to vote at any meeting of
Holders a Person shall (a) be a Holder of one or more Outstanding Securities or
(b) be a Person appointed by an instrument in writing as proxy by a Holder of
one or more Securities; provided, however, that in the case of any meeting of
Holders with respect to the Securities of a series all or part of which are
represented by a Book-Entry Security, only Holders, or their designated
proxies, of record on the record date established pursuant to Section 13.3
hereof shall be entitled to vote at such meeting. The only Persons who shall be
entitled to be present or to speak at any meeting of Holders shall be the
Persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

SECTION 13.4  Quorum; Action.

            The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of a specified
percentage in aggregate principal amount of Outstanding Securities of a series
that is less or greater than a majority in principal amount of the Outstanding
Securities of a series, then, with respect to such action (and only such
action) the Persons entitled to vote such lesser or greater percentage in
principal amount of the Outstanding Securities of such series shall constitute
a quorum. In the absence of a quorum within 30 minutes of the time appointed
for any such meeting, the meeting shall, if convened at the request of Holders
of Securities of such series, be dissolved. In any other case the meeting may
be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of





                                       77
<PAGE>   86
such meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such adjourned meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 13.2 (a), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned
meeting shall state expressly the percentage, as provided above, of the
principal amount of the outstanding Securities of such series which shall
constitute a quorum.  Notwithstanding the foregoing, no meeting of Holders with
respect to Securities of any Series which is represented in whole or in part by
a Book-Entry Security, shall be adjourned to a date more than 90 days after the
record date for such meeting unless the Trustee shall send out a new notice of
meeting and establish, in accordance with Section 13.3, a new record date for
Holders entitled to vote at such meeting.

            Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum
is present as aforesaid may be adopted by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2 any
resolution with respect to any consent or waiver which this Indenture expressly
provides may be given by the Holders of a specified percentage in aggregate
principal amount of Outstanding Securities of a series that is less or greater
than a majority in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly convened and at which
a quorum is present as aforesaid only by the affirmative vote of the Holders of
such specified percentage in principal amount of the Outstanding Securities of
that series.

            Any resolution passed or decision taken at any meeting of Holders
of Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related
Coupons, whether or not present or represented at the meeting.

SECTION 13.5  Determination of Voting Rights; Conduct and Adjournment of
              Meetings.

            (a)  Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section
1.4 and the appointment of any proxy shall be proved in the manner specified in
Section 1.4 or by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.4 to certify to the holding of Bearer Securities. Such regulations
may provide





                                       78
<PAGE>   87
that written instruments appointing proxies, regular on their face, may be
presumed valid and genuine without the proof specified in Section 1.4 or other
proof.

            (b)  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 13.2(b), in
which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

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

            (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 13.2 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 13.6  Counting Votes and Recording Action of Meetings.

            The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 13.2 and, if
applicable, Section 13.4. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                            CONVERSION OF SECURITIES

SECTION 14.1  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 3.1 for the Securities of such series. The terms and provisions
applicable to the conversion of Securities of any series into securities of the
Company (other than Common Stock) shall, if applicable, be set forth in an
Officers' Certificate or established in one or more indentures supplemental
hereto, prior to the issuance of Securities of such series in accordance with
Section 3.1.

SECTION 14.2  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
10.2, accompanied by written notice to the Company 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 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 such period) 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 3.7 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 3.1, 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 conver-





                                       80
<PAGE>   89
sion. 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 certifi cate 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 3.7, no
payment or adjustment shall be made upon any conversion on account of any
interest accrued on the Securities surrendered for conversion or on account of
any dividends on the Common Stock 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 14.3  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 14.3, 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, on
the basis of the last reported sale price regular way on such exchange 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,
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





                                       81
<PAGE>   90
traded on the New York Stock Exchange, or if the Common Stock is not traded on
the New York Stock Exchange, on the principal exchange or market on which the
Common Stock is traded or quoted.

SECTION 14.4  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, reclassification, 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 10.2 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 14.5  Notice of Certain Corporate Actions.

            In case:

                  (a)  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); or

                  (b)  the Company shall authorize the granting to 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

                  (c)  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

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





                                       82
<PAGE>   91
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
(a) or (b) 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 14.6  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 or
treasury shares, 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 14.7  Payment of Certain Taxes upon Conversion.

            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 14.8  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 14.9  Effect of Consolidation or Merger on Conversion Privilege.

            In case of any consolidation of the Company with, or merger of the
Company into or with any other Person, or in case of any sale of all or
substantially all of the assets of the





                                       83
<PAGE>   92
Company, the Company or the Person formed by such consolidation or the Person
into which the Company shall have been merged or the Person which shall have
acquired such assets, as the case may be, shall execute and deliver to the
Trustee a supplemental indenture providing that the Holder of each Security
then outstanding of any series that is convertible into Common Stock of the
Company shall have the right, which right shall be the exclusive conversion
right thereafter available to said Holder (until the expiration of the
conversion right of such Security), to convert such Security into the kind and
amount of shares of stock or other securities or property (including cash)
receivable upon such consolidation, merger or sale 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 or sale, subject to
compliance with the other provisions of this Indenture, such Security and such
supplemental indenture. Such supplemental indenture shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in such Security. The above provisions of this Section
shall similarly apply to successive consolidations, mergers or sales. It is
expressly agreed and understood that anything in this Indenture to the contrary
notwithstanding, if, pursuant to such merger, consolidation or sale, holders of
outstanding shares of Common Stock of the Company do not receive shares of
common stock of the surviving corporation but receive other securities, cash or
other property or any combination thereof, Holders of Securities shall not have
the right to thereafter convert their Securities into common stock of the
surviving corporation or the corporation which shall have acquired such assets,
but rather, shall have the right upon such conversion to receive the other
securities, cash or other property receivable by a holder of the number of
shares of Common Stock of the Company into which the Securities held by such
holder might have been converted immediately prior to such consolidation,
merger or sale, all as more fully provided in the first sentence of this
Section 14.9. Anything in this Section 14.9 to the contrary notwithstanding,
the provisions of this Section 14.9 shall not apply to a merger or
consolidation of another corporation with or into the Company pursuant to which
both of the following conditions are applicable: (i) the Company is the
surviving corporation and (ii) the outstanding shares of Common Stock of the
Company are not changed or converted into any other securities or property
(including cash) or changed in number or character or reclassified pursuant to
the terms of such merger or consolidation.

            As evidence of the kind and amount of shares of stock or other
securities or property (including cash) into which Securities may properly be
convertible after any such consolidation, merger or sale, or as to the
appropriate adjustments of the conversion prices applicable with respect
thereto, the Trustee shall be furnished with and may accept the certificate or
opinion of an independent certified public accountant with respect thereto;
and, in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely thereon, and shall not be responsible or accountable to any
Holder of Securities for any provision in conformity therewith or approved by
such independent certified accountant which may be contained in said
supplemental indenture.

SECTION 14.10  Duties of Trustee Regarding Conversion.





                                       84
<PAGE>   93
            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.
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 XIV 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.
All Securities delivered for conversion shall be delivered to the Trustee to be
cancelled by or at the direction of the Trustee, which shall dispose of the
same as provided in Section 3.9.

SECTION 14.11  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 funds deposited for the sinking fund
referred to in Article III hereof) and which shall not be required for such
purposes because of the conversion of such Securities as provided in this

given or taken by Holders of such series may, alternatively, be embodied in and

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

            (c)  The principal amount and serial numbers of Registered
Securities held by any Person, and the date of holding the same, shall be
proved by the Security Register.

depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be





                                       10
<PAGE>   19
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

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

            (f)  With respect to the Securities of any Series, upon receipt by
the Trustee of (i) any written notice directing the time, method or place of
conducting any proceeding or exercising any trust or power pursuant to Section
5.12 with respect to Securities of such series or (ii) any written demand,
request or notice with respect to any matter on which the Holders of Securities
of such series are entitled to act under this Indenture, in each case from
Holders of less than, or proxies representing less than, the requisite
principal amount of Outstanding Securities or such series entitled to give such
demand, request or notice, the Trustee shall establish a record date for
determining Holders of Outstanding Securities of such series entitled to join
in such demand, request or notice, which record date shall be the close of
business on the day the Trustee received such demand, request or notice. The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such demand, request or notice whether or
not such Holders remain Holders after such record date; provided, however, that
unless the Holders of the requisite principal amount of Outstanding Securities
of such series shall have joined in such demand, request or notice prior to the
day which is the ninetieth day after such record date, such demand, request or
notice shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or
a proxy of a Holder, from giving, (i) after the expiration of such 90-day
period, a new demand, request or notice identical to a demand, request or
notice which has been canceled pursuant to the proviso to the preceding
sentence or (ii) during any such 90-day period, a new demand, request or notice
which has been canceled pursuant to the proviso to the preceding sentence or
(iii) during any such 90-day period, a new demand, request or notice contrary
to or different from such demand, request or notice, in either of which events
a new record date shall be established pursuant to the provisions of this
clause.

            (g)  The Company may set any day as the record date for the purpose
of determining the Holders of Outstanding Securities of any series entitled to
give or take any request, demand,





                                       11
<PAGE>   20
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Indenture to be given or taken by Holders of Securities of
such series. With regard to any record date set pursuant to this paragraph, the
Holders of Outstanding Securities of the relevant series on such record date
(or their duly appointed agents), and only such Persons, shall be entitled to
give or take the relevant action, whether or not such Holders remain Holders
after such record date. With regard to any action that may be given or taken
hereunder only by Holders of a requisite principal amount of Outstanding
Securities of any series (or their duly appointed agents) and for which a
record date is set pursuant to this paragraph, the Company may, at its option,
set an expiration date after which no such action purported to be given or
taken by any Holder shall be effective hereunder unless given or taken on or
prior to such expiration date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents). On or prior to any expiration date set pursuant to this
paragraph, the Company may, on one or more occasions at its option, extend such
date to any later date. Nothing in this paragraph shall prevent any Holder (or
any duly appointed agent thereof) from giving or taking, after any expiration
date, any action identical to, or, at any time, contrary to or different from,
any action given or taken, or purported to have been given or taken, hereunder
by a Holder on or prior to such date, in which event the Company may set a
record date in respect thereof pursuant to this paragraph. Notwithstanding the
foregoing or the Trust Indenture Act, the Company shall not set a record date
for, and the provisions of this paragraph shall not apply with respect to, any
action to be given or taken by Holders pursuant to Section 5.1, 5.2 or 5.12.

SECTION 1.5  Notices, Etc., to Trustee and Company.

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

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

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

SECTION 1.6  Notice to Holders of Securities; Waiver.

            Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event:

                  (1)  such notice shall be sufficiently given to Holders of
                  Registered Securities if in writing and mailed, first-class
                  postage prepaid, to each Holder of a Registered Security
                  affected by such event, at the address of such Holder as it
                  appears in the Security Register, not earlier than the
                  earliest date, and not later than the latest date, prescribed
                  for the giving of such notice; and

                  (2)  such notice shall be sufficiently given to Holders of
                  Bearer Securities if published in an Authorized Newspaper in
                  The City of New York, The City of London and in such other
                  city or cities as may be specified in such Securities on a
                  Business Day at least twice, the first such publication to be
                  not earlier than the earliest date, and not later than the
                  latest date, prescribed for the giving of such notice.

            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 to
Holders of Registered Securities by mail, then such notification as shall be
made with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. In any case where notice to Holders
of Registered Securities is given by mail, neither the failure to mail such
notice, nor any defect in any notice mailed to any particular Holder of a
Registered Security shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein.

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

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


SECTION 1.7  Language of Notices, Etc.





                                       13
<PAGE>   22
            Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of
the country of publication.

SECTION 1.8  Conflict with Trust Indenture Act.

            If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by, or with another provision
(an "incorporated provision") included in this Indenture by operation of
Sections 310 to 318, inclusive, of the Trust Indenture Act, such imposed duties
of incorporated provision shall control.

SECTION 1.9  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 1.10  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 1.11  Separability Clause.

            In case any provision in this Indenture or the Securities or
Coupons 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 1.12  Benefits of Indenture.

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

SECTION 1.13  Governing Law.

            This Indenture and the Securities and Coupons shall be governed by
and construed in accordance with the laws of the State of New York without
regard to conflicts of laws.


SECTION 1.14  Legal Holidays.





                                       14
<PAGE>   23
            In any case where any Interest Payment Date, Redemption Date,
sinking fund payment date, Maturity or Stated Maturity of any Security shall
not be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture or of the Securities or Coupons other than a
provision in the Securities of any series which specifically states that such
provision shall apply in lieu of this Section) payment of interest or principal
(and premium, if any) need not be made at such Place of Payment on such date,
but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity, provided that no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be, to such
succeeding Business Day.

SECTION 1.15  Judgment Currency.

            The Company agrees, to the fullest extent that it may effectively
do so under applicable law, that (a) if for the purpose of obtaining judgment
in any court it is necessary to convert the sum due on the Securities of any
series from the currency in which such sum is payable in accordance with the
terms of such Securities (the "Required Currency") into a currency in which a
judgment will be rendered (the "Judgment Currency"), the rate of exchange used
shall be the rate at which in accordance with normal banking procedures the
Trustee could purchase in The City of New York the Required Currency with the
Judgment Currency on the New York Banking Day preceding that on which a final
unappealable judgment is rendered and (b) its obligations under this Indenture
to make payments in the Required Currency (i) shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with subsection (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture.  For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or required by law or executive order to
close.

SECTION 1.16      Immunity of Incorporators, Shareholders, Officers, Directors
                  and Employees.

            No recourse under or upon any obligation, covenant or agreement of
this Indenture, or of any Security, or for any claim based thereon or otherwise
in respect thereof, shall be had against any incorporator, shareholder,
officer, director or employee, as such, past, present or future, of the Company
or of any successor corporation, either directly or through the Company,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of





                                       15
<PAGE>   24
any assessment or penalty or otherwise; it being expressly understood that this
Indenture and the obligations issued hereunder are solely corporate obligations
of the Company, and that no such personal liability whatever shall attach to,
or is or shall be incurred by, the incorporators, shareholders, officers,
directors or employees, as such, of the Company or of any successor
corporation, or any of them, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations or agreements contained in
this Indenture or in any of the Securities or implied therefrom; and that any
and all such personal liability, either at common law or in equity or by
constitution or statute, of, and any and all such rights and claims against,
every such incorporator, shareholder, officer, director or employee, as such,
because of the creation of the indebtedness hereby authorized, or under of by
reason of the obligations or agreements contained in this Indenture or in any
of the Securities or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issue of such Securities.

            All payments of interest and other amounts, if any, to be made by
the Trustee hereunder shall be made only from the money deposited with the
Trustee and only to the extent that the Trustee shall have sufficient income or
proceeds to make such payments in accordance with the terms of this Indenture,
and each holder hereof, by its acceptance of a Security, agrees that it will
look solely to the income and proceeds deposited with the Trustee to the extent
available for distribution to the holder hereof as provided and that the
Trustee is not personally liable in any manner to the holder hereof for any
amounts payable or any liability under this Indenture or any Security.

                                 SECURITY FORMS

SECTION 2.1  Forms Generally.

            The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related Coupons shall be in such form
(including temporary or permanent global form) as shall be established by or
pursuant to a Board Resolution or in one or more indentures supplemental
hereto, in each case with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by this Indenture, and may
have such letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with the rules of any
securities exchange or as may, consistently herewith, be determined by the
officers executing such Securities or Coupons, as evidenced by their execution
of the Securities or Coupons. If temporary Securities of any series are issued
in global form as permitted by Section 3.4, the form thereof shall be
established as provided in the preceding sentence. If the forms of Securities
or Coupons of any series (or any such temporary global Security) are
established by action taken pursuant to a Board Resolution, a copy of an
appropriate record of such action shall be certified by the





                                       16
<PAGE>   25
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Company Order contemplated by Section 3.3 for the
authentication and delivery of such Securities (or any such temporary global
Security) or Coupons.

            Unless otherwise specified as contemplated by Section 3.1, Bearer
Securities shall have interest Coupons attached.

            The definitive Securities and Coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities or

                                        As Trustee

                                        By

SECTION 2.3  Securities in Global Form.

            If Securities of a series are issuable in global form, as specified
as contemplated by Section 3.1, then, notwithstanding clause (12) of Section
3.1 and the provisions of Section 3.2, any such Security shall represent such
of the Outstanding Securities of such series as shall be specified therein and
may provide that it shall represent the aggregate amount of Outstanding
Securities from time to time endorsed thereon and that the aggregate amount of
Outstanding Securities represented thereby may from time to time be reduced to
reflect exchanges. Any endorsement of a Security in global form to reflect the
amount, or any increase or decrease in the amount, of Outstanding Securities
represented thereby shall be made by the Trustee in such manner and upon
instructions given by such Person or Persons as shall be specified therein or
in the Company Order to be delivered to the Trustee pursuant to Section 3.3 or
Section 3.4. Subject to the provisions of Section 3.3 and, if appli cable,
Section 3.4, the Trustee shall deliver and redeliver any Security in permanent
global form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 3.3 or 3.4 has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or





                                       17
<PAGE>   26
redelivery of a Security in global form shall be in writing but need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel.

            The provisions of the last sentence of Section 3.3 shall apply to
any Security represented by a Security in global form if such Security was
never issued and sold by the Company and the Company delivers to the Trustee
the Security in global form together with written instructions (which need not
comply with Section 1.2 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 3.3.

            Notwithstanding the provisions of Sections 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of and
any premium and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein.

            Notwithstanding the provisions of Section 3.8 and except as
provided in the preceding paragraph, the Company, the Trustee and any agent of
the Company and the Trustee shall treat a Person as the Holder of such
principal amount of Outstanding Securities represented by a permanent global
Security as shall be specified in a written statement of the Holder of such
permanent global Security or, in the case of a permanent global Security in
bearer form, of Euroclear or Cedel S.A. which is provided to the Trustee by
such Person.

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

            "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee
only in the limited circumstances described in the Indenture, and no transfer
of this Security (other than a transfer of this Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except
in such limited circumstances."

SECTION 2.5  Form of Conversion Notice.

            The form of conversion notice for the conversion of Securities into
shares of Common Stock or other securities of the Company shall be in
substantially the form included with the applicable form of Securities as shall
be established pursuant to Section 2.1 hereinabove.

or established in one or more indentures supplemental hereto, prior to the
issuance of Securities of any series:

                  (1)  the title of the Securities of the series (which shall

                  series of Securities);

                  (2)  any limit upon the aggregate principal amount of the
                  Securities of the series which may be authenticated and

                  authenticated and delivered upon registration of transfer of,

                  series pursuant to Section 3.4, 3.5, 3.6, 9.6 or 11.7 and
                  except for any Securities which, pursuant to Section 3.3, are
                  deemed never to have been authenticated and delivered
                  hereunder);

                  (3)  whether Securities of the series are to be issuable as

                  Securities of the series are to be issuable initially in
                  temporary global form and whether any Securities of the
                  series are to be issuable in permanent global form with or
                  without Coupons and, if so, whether beneficial owners of
                  interests in any such permanent global Security may exchange
                  such interests for Securities of such series and of like
                  tenor of any authorized form and denomination and the
                  circumstances under which any such exchanges may occur, if
                  other than in the manner provided in Section 3.5;

                  Security of the series shall be payable, if other than the
                  Person in whose name that Security (or one or more
                  Predecessor Securities) is registered at the close of
                  business on the Regular Record Date for such interest, the
                  manner in which, or the Person to whom, any interest on any
                  Bearer Security of the series shall be payable, if otherwise
                  than upon presentation and surrender of the Coupons
                  appertaining thereto as they severally mature, and the extent
                  to which, or the manner in which, any interest payable on a
                  temporary global Security on an Interest Payment Date will be
                  paid if other than in the manner provided in Section 3.4;

                  (5)  the date or dates, or the method by which such date or

                  of the Securities of the series is payable;

                  or purchase Securities of the series, or particular
                  Securities within the series, pursuant to any sinking fund or
                  analogous provisions or at the option of a Holder thereof,

                  of and any premium and interest on Securities of such series

                  premium or interest on the Securities of the series may be
                  determined with reference to an index, the manner in which
                  such amounts shall be determined;

                  of the principal amount of any Securities of the series which
                  shall be payable upon declaration of acceleration of the
                  Maturity thereof pursuant to Section 5.2;

                  (17)  the Person who shall be the Security Registrar, if
                  other than the Trustee;

                  Book-Entry Security may be registered to, a Person other than
                  such Depository or its nominee, if other than as set forth in
                  Section 3.5;

                  (19)  if the provisions of Section 4.4 or 4.5 are applicable
                  to the Securities of such series;

                  (20)  provisions, if any, granting special rights to the
                  Holders of Securities of the series upon the occurrence of
                  such events as may be specified;

                  (21)  any deletions from, modifications of or additions to
                  the Events of Default or covenants of the Company with
                  respect to Securities of the series, whether or not





                                       21
<PAGE>   30
                  such Events of Default or covenants are consistent with the
                  Events of Default or covenants set forth herein;

                  (22)  whether and under what conditions additional amounts
                  will be payable to Holders of Securities of the series
                  pursuant to Section 10.4; and

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

            All Securities of any one series and the Coupons appertaining to
any Bearer Securities of such series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 3.3) set forth in, or determined in the manner provided
in, the Officers' Certificate referred to above or in any such indenture
supplemental hereto.  Not all Securities of any one series need be issued at
the same time, and, unless otherwise provided, a series may be reopened for
issuances of additional Securities of such series.

            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 of the Company and delivered to the Trustee
at or prior to the delivery of the Officers' Certificate setting forth the
terms, or the manner of determining the terms, of the series.

SECTION 3.2  Denominations.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to any series of Securities, any Registered Securities of a series
shall be issuable in denominations of $1,000 and any integral multiple thereof
and any Bearer Securities of a series shall be issuable in the denomination of
$5,000.

SECTION 3.3  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 President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secre taries. The signature of any of
these officers on the Securities may be manual or facsimile. Coupons shall bear
the facsimile signature of the Treasurer of the Company.

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





                                       22
<PAGE>   31
tication 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, together
with any Coupons appertaining thereto executed by the Company to the Trustee
for authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided,
further, that a Bearer Security may be delivered in connection with its
original issuance only if the Person entitled to receive such Bearer Security
shall have furnished a certificate in the form specified in such Security as to
certain tax matters in respect of United States citizens, dated no earlier than
15 days prior to the earlier of the date on which such Bearer Security is
delivered and the date on which any temporary global Security first becomes
exchangeable for such Bearer Security in accordance with the terms of such
temporary global Security and this Indenture. If any Security shall be
represented by a permanent global Bearer Security, then, for purposes of this
Section and Section 3.4, the notation of a beneficial owner's interest therein
upon original issuance of such Security or upon exchange of a portion of a
temporary global Security shall be deemed to be delivery in connection with its
original issuance of such beneficial owner's interest in such permanent global
Security. Except as permitted by Section 3.6, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant Coupons for
interest then matured have been detached and cancelled.

            If all the Securities of any series are not to be issued at one
time and if the Board Resolution and indenture supplement establishing such
series shall so permit, such Company Order may set forth procedures acceptable
to the Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate, maturity date,
date of issuance and date from which interest shall accrue.

            If the forms or terms of the Securities of the series and any
related Coupons have been established in or pursuant to one or more Board
Resolutions as permitted by Sections 2.1 and 3.1, 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 6.1) shall be fully protected in relying upon, an Opinion
of Counsel stating:

                  (a)  that such forms have been established in conformity with
                  the provisions of this Indenture;

                  (b)  that such terms, or the manner of determining such
                  terms, have been established in conformity with the
                  provisions of this Indenture;

                  (c)  that such Securities, together with any Coupons
                  appertaining thereto, when authenticated and delivered by the
                  Trustee and issued by the Company in the man-





                                       23
<PAGE>   32
                  ner 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, as to enforcement, to bankruptcy,
                  insolvency, reorganization and other laws of general
                  applicability relating to or affecting the enforcement of
                  creditors' rights and to general equity principles; and

                  (d)  that all applicable laws and requirements in respect of
                  the execution and delivery by the Company of such Securities
                  have been complied with.

            If such forms or terms have been so established, the Trustee shall
not be required to authenticate such Securities if the issue or 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 3.1 and of the two
preceding paragraphs, 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 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraphs at
or prior to the time of 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 Registered Security shall be dated the date of its
authentication; and each Bearer Security shall be dated as of the date of
original issuance of the first Security of such series to be issued.

            No Security or Coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security, or the Security to which such Coupon appertains, 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 3.9 together with a written
statement (which need not comply with Section 1.2 and need not be accompanied
by an Opinion of Counsel) stating that such Security has never been issued and
sold by the Company, for all purposes of this Indenture such Security shall be
deemed never to have been authenticated and delivered hereunder and shall never
be entitled to the benefits of this Indenture.

SECTION 3.4  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





                                       24
<PAGE>   33
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Securities in lieu of which they are issued, in registered form or,
if authorized, in bearer form with one or more Coupons or without Coupons, and
with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Securities or Coupons may determine, as
evidenced by their execution of such Securities or Coupons. In the case of any
series issuable as Bearer Securities, such temporary Securities may be in
global form. A temporary Bearer Security shall be delivered only in compliance
with the conditions set forth in Section 3.3.

            Except in the case of temporary Securities in global form (which
shall be exchanged in accordance with the provisions of the following
paragraphs), 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 maintained pursuant to Section
10.2 in a Place of Payment for such series for the purpose of exchanges of
Securities of such series, without charge to the Holder. Upon surrender for
cancellation of any one or more temporary Securities of any series (accompanied
by any unmatured Coupons appertaining thereto) the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like
aggregate principal amount of definitive Securities of the same series and of
like tenor of authorized denominations; provided, however, that no definitive
Bearer Security shall be delivered in exchange for a temporary Registered
Security.

            If temporary Securities of any series are issued in global form,
any such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the
"Common Depositary"), for the benefit of Euroclear and Cedel S.A., for credit
to the respective accounts of the beneficial owners of such Securities (or to
such other accounts as they may direct).

            Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities of that series, in aggregate principal amount equal to
the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Secu rity shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities of such series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of
such temporary global Security to be exchanged; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation
by the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by
Euroclear as to the portion of such tempo-





                                       25
<PAGE>   34
rary global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by Cedel
S.A. as to the portion of such temporary global Security held for its account
then to be exchanged, each in the form or in such form as shall be specified in
such Security. The definitive Securities to be delivered in exchange for any
such temporary global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any
combination thereof, as specified as contemplated by Section 3.1, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof; provided, however, that definitive Bearer Securities shall be
delivered in exchange for a portion of a temporary global Security only in
compliance with the requirements of Section 3.3.

            Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or Cedel S.A., as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Cedel S.A., as the case may be, a
certificate in such form as shall be specified in such Security, dated no
earlier than 15 days prior to the Exchange Date, copies of which certificate
shall be available from the offices of Euroclear and Cedel S.A., the Trustee,
any Authenticating Agent appointed for such series of Securities and each
Paying Agent. Unless otherwise specified in such temporary global Security, any
such exchange shall be made free of charge to the beneficial owners of such
temporary global Security, except that a Person receiving definitive Securities
must bear the cost of insurance, postage, transportation and the like in the
event that such Person does not take delivery of such definitive Securities in
person at the offices of Euroclear or Cedel S.A. Definitive Securities in
bearer form to be delivered in exchange for any portion of a temporary global
Security shall be delivered only outside the United States.

            Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 3.1, interest payable on a temporary
global Security on an Interest Payment Date for Securities of such series
occurring prior to the applicable Exchange Date shall be payable to Euroclear
and Cedel S.A. on such Interest Payment Date upon delivery by Euroclear and
Cedel S.A. to the Trustee of a certificate or certificates in such form as
shall be specified in such Security, for credit with out further interest on or
after such Interest Payment Date to the respective accounts of the Persons who
are the beneficial owners of such temporary global Security on such Interest
Payment Date and who have each delivered to Euroclear or Cedel S.A., as the
case may be, a certificate in such form as shall be specified in such Security.
Any interest so received by Euroclear and Cedel S.A. and not paid as herein
provided shall be returned to the Trustee immediately prior to the expiration
of two years after such Interest Payment Date in order to be repaid to the
Company in accordance with Section 10.3.

SECTION 3.5  Registration, Registration of Transfer and Exchange.





                                       26
<PAGE>   35
            The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with Section 10.2 a register (the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Registered
Securities and the registration of transfers of Registered Securities. The
Trustee is hereby appointed "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein
provided.

            Upon due surrender for registration of transfer of any Registered
Security of any series at the office or agency of the Company maintained
pursuant to Section 10.2 for such purpose in a Place of Payment for such
series, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Registered Securities of the same series of any authorized denominations
and of a like aggregate principal amount and tenor.

            At the option of the Holder, Registered Securities of any series
may be exchanged for other Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at any 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. Registered Securities
may not be exchanged for Bearer Securities.

            At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured Coupons, and all matured Coupons in default
appertaining thereto. If the Holder of a Bearer Security is unable to produce
any such unmatured Coupon or Coupons or matured Coupon or Coupons in default,
such exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company in an amount equal to the face
amount of such missing Coupon or Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there is
furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such
Securities shall surrender to any Paying Agent any such missing Coupon in
respect of which such a payment shall have been made, such Holder shall be
entitled to receive the amount of such payment; provided, however, that, except
as otherwise provided in Section 10.2, interest represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an office or
agency located outside the United States. Notwithstanding the foregoing, in
case a Bearer Security of any series is surrendered at any such office or
agency in exchange for a Registered Security of the same series and like tenor
after the close of business at such office or agency on (i) any Regular Record
Date and before the opening of business at such office or agency on the
relevant Interest Payment Date, or (ii) any Special Record Date and before the
opening of business at such office or agency on the related proposed date for
payment of Defaulted Interest, such Bearer Security shall be surrendered
without the Coupon relating to





                                       27
<PAGE>   36
such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

            Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

            Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 3.1, any permanent global Security shall be
exchangeable only as provided in this paragraph. If the beneficial owners of
interests in a permanent global Security are entitled to exchange such
interests for Securities of such series and of like tenor and principal amount
of another authorized form and denomination, as specified as contemplated by
Section 3.1, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities of that series in aggregate
principal amount equal to the principal amount of such permanent global
Security, executed by the Company. On or after the earliest date on which such
interests may be so exchanged, such permanent global Security shall be
surrendered by the Common Depositary or such other depositary or Common
Depositary as shall be specified in the Company Order with respect thereto to
the Trustee, as the Company's agent for such purpose, to be exchanged, in whole
or from time to time in part, for definitive Securities of such series without
charge and the Trustee shall authenticate and deliver, in exchange for each
portion of such permanent global Security, a like aggregate principal amount of
definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such permanent global Security to be exchanged
which, unless the Securities of the series are not issuable both as Bearer
Securities and as Registered Securities, as specified as contemplated by
Section 3.1, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof; provided, however, that no Bearer Security delivered in exchange
for a portion of a permanent global Security shall be mailed or otherwise
delivered to any location in the United States. If a Registered Security is
issued in exchange for any portion of a permanent global Security after the
close of business at the office or agency where such exchange occurs on (i) any
Regular Record Date and before the opening of business at such office or agency
on the relevant Interest Payment Date, or (ii) any Special Record Date and
before the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent global Security is payable in accordance with the provisions
of this Indenture.

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

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

            No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

            The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before any selection of Securities of that
series to be redeemed and ending at the close of business on (A) if Securities
of the series are issuable only as Registered Securities, the day of the
mailing of the relevant notice of redemption and (B) if Securities of the
series are issuable as Bearer Securities, the day of the first publication of
the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, (ii) to register the transfer of or exchange
any Registered Security so selected for redemption, in whole or in part, except
the unredeemed portion of any Security being redeemed in part, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption.

            Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 3.1, any Book-Entry Security shall be exchangeable
pursuant to this Section 3.5 or Sections 3.4, 9.6 and 11.7 for Securities
registered in the name of, and a transfer of a Book-Entry Security or any
series may be registered to, any Person other than the Depository for such
Security or its nominee only if (i) such Depository notifies the Company that
it is unwilling or unable to continue as Depository for such Book-Entry
Security or if at any time such Depository ceases to be a clearing agency
registered under the Securities Exchange Act of 1934, as amended, (ii) the
Company executes and delivers to the Trustee a Company Order that such
Book-Entry Security shall be so exchangeable and the transfer thereof so
registerable or (iii) there shall have occurred and be continuing an Event of
Default, or an event which after notice or lapse of time would be an Event of
Default, with respect to the Securities of such series. Upon the occurrence in
respect of any Book-Entry Security of any series of any one or more of the
conditions specified in clauses (i), (ii) or (iii) or the preced-





                                       29
<PAGE>   38
ing sentence or such other conditions as may be specified as contemplated by
Section 3.1 for such series, such Book-Entry Security may be exchanged for
Securities registered in the names of, and the transfer of such Book-Entry
Security may be registered to, such Persons (including Persons other than the
Depository with respect to such series and its nominees) as such Depository
shall direct. Notwithstanding any other provision of this Indenture, any
Security authenticated and delivered upon registration of transfer of, or in
exchange for, or in lieu of, any Book-Entry Security shall also be a Book-Entry
Security and shall bear the legend specified in Section 2.4 except for any
Security authenticated and delivered in exchange for, or upon registration of
transfer of, Book-Entry Security pursuant to the preceding sentence.

                  Notwithstanding anything in this Indenture or in the terms of
a Security to the contrary, the exchange of Bearer Securities for Registered
Securities will be subject to satisfaction of the provisions of the United
States Federal income tax laws in effect at the time of such exchange.  None of
the Company, the Trustee or any Authenticating Agent of the Company or the
Trustee (any of which, other than the Company, shall rely on an Officers'
Certificate and an Opinion of Counsel) shall be required to exchange any Bearer
Security for a Registered Security if as a result thereof and in the Company's
reasonable judgment, the Company would incur adverse consequences under then
applicable United States Federal income tax laws.

SECTION 3.6  Mutilated, Destroyed, Lost and Stolen Securities and Coupons.

            If any mutilated Security or a Security with a mutilated Coupon
appertaining thereto 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, with Coupons corresponding to the
Coupons, if any, appertaining to the surrendered Security and such mutilated
Security or a Security with a mutilated Coupon, if any, shall be cancelled by
the Trustee in accordance with the Indenture.

            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 or Coupon and (ii) such security or in demnity as may be required by
them, then, in the absence of notice to the Company or the Trustee that such
Security or Coupon has been acquired by a bona fide purchaser, the Company
shall, subject to the following paragraph, execute, and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
Coupon appertains (with all appurtenant Coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with Coupons corresponding
to the Coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen Coupon appertains.





                                       30
<PAGE>   39
            In case any such mutilated, destroyed, lost or stolen Security or
Coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security or Coupon;
provided, however, that principal of and any premium and interest on Bearer
Securities shall, except as otherwise provided in Section 10.2, be payable only
at an office or agency located outside the United States.

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

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

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

SECTION 3.7  Payment of Interest; Interest Rights Preserved.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to any series of Securities, interest on any Registered 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; provided, however, that each installment
of interest on any Registered Security may at the Company's option be paid by
(i) mailing a check for such interest, payable to or upon the written order of
the Person entitled thereto pursuant to Section 3.8, to the address of such
Person as it appears on the Security Register or (ii) transfer to an account
maintained by the payee located inside the United States.

            Unless otherwise provided as contemplated by Section 3.1 with
respect to the Securities of any series, payment of interest may be made, in
the case of a Bearer Security, by transfer to an account maintained by the
payee with a bank located outside the United States.

            Unless otherwise provided as contemplated by Section 3.1, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such





                                       31
<PAGE>   40
permanent global Security held for its account by Cede & Co. or the Common
Depositary, as the case may be, for the purpose of permitting such party to
credit the interest received by it in respect of such permanent global Security
to the accounts of the beneficial owners thereof.

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

            Any interest on any Registered 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) and (2) below:

                  (1)  The Company may elect to make payment of any Defaulted
                  Interest to the Persons in whose names the Registered
                  Securities of such series (or their respective Predecessor
                  Securities) are registered at the close of business on a
                  Special Record Date for the payment of such Defaulted
                  Interest, which shall be fixed in the following manner. The
                  Company shall notify the Trustee in writing of the amount of
                  Defaulted Interest proposed to be paid on each Registered
                  Security of such series and the date of the proposed payment,
                  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 mailed, first-class postage
                  prepaid, to each Holder of Registered Securities of such
                  series at the address of such Holder as it appears in the
                  Security Register, not less than 10 days prior to such
                  Special Record Date. Notice of the proposed payment of such
                  Defaulted Interest and the Special Record Date therefor
                  having been so mailed, such Defaulted Interest shall be paid
                  to the Persons in whose names the Registered Securities of
                  such series (or their respective Predecessor Securities) are
                  registered





                                       32
<PAGE>   41
                  at the close of business on such Special Record Date and
                  shall no longer be payable pursuant to the following Clause
                  (2); and

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

            Subject to the foregoing provisions of this Section and Section
3.5, 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.

            In the case of any Security which is converted into Common Stock of
the Company after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security whose Maturity is
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 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 preced ing sentence, in the case of any Security which is
converted, interest whose Stated Maturity is after the date of conversion of
such Security shall not be payable.

SECTION 3.8  Persons Deemed Owners.

            Prior to due presentment of a Registered Security for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Registered Security is
registered as the owner of such Registered Security for the purpose of
receiving payment of principal of (and premium, if any) and (subject to
Sections 3.5 and 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security shall 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.

            Title to any Bearer Security and any Coupons appertaining thereto
shall pass by delivery. The Company, the Trustee and any agent of the Company
or the Trustee may treat the bearer of any Bearer Security and the Bearer of
any Coupon as the absolute owner of such Security or Coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or Coupon shall 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.





                                       33
<PAGE>   42
            Except as provided in Section 3.5, owners of beneficial interests
in a Global Security shall not be entitled to have Securities represented by
such Global Security registered in their names, shall not receive or be
entitled to receive physical delivery of Securities in certificated form and
shall not be considered the Holders thereof for any purpose under this
Indenture.  Members or participants in the Depository shall have no rights
under this Indenture with respect to any Global Security held on their behalf
by the Depository, and such Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the Holder of such
Global Security under this Indenture.  Notwithstanding the foregoing, with
respect to any Global Security,  nothing herein shall prevent the Company, the
Trustee, or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by the
Depository, as a Holder, with respect to such Global Security or impair, as
between the Depository and owners of beneficial interests in such Global
Security, the operation of customary practices governing the exercise of the
rights of the Depository (or its nominee) as Holder of such Global Security.

            None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests or for the delivery to
any member of or participants in the Depository of any notice permitted or
required to be given to the Holders of the Securities under this Indenture.

SECTION 3.9  Cancellation.

            All Securities and Coupons 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. All Registered Securities and matured Coupons so
delivered shall be promptly cancelled by the Trustee. All Bearer Securities and
unmatured Coupons so delivered shall be cancelled. All Bearer Securities and
unmatured Coupons held by the Trustee pending such cancellation or reissuance
shall be deemed to be delivered for cancellation for all purposes of this
Indenture and the Securities. 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 cancelled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by this Indenture. All cancelled Securities and
Coupons held by the Trustee shall be disposed of as directed by a Company
Order, or in the absence of a Company Order, may be destroyed by the Trustee;
provided, however, that the Trustee shall not be required to destroy such
cancelled Securities.

            Notwithstanding the foregoing, with respect to any Book-Entry
Security, nothing herein shall prevent the Company, the Trustee or any agent of
the Company or the Trustee, from





                                       34
<PAGE>   43
giving effect to any written certification, proxy or other authorization
furnished by a Depository or impair, as between a Depository and holders of
beneficial interests in any Book-Entry Security, the operation of customary
practices governing the exercise of the rights of the Depositary (or its
nominee) as Holder of such Book-Entry Security.

SECTION 3.10  Computation of Interest.

            Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

SECTION 3.11  Electronic Security Issuance.

            The Securities may, pursuant to a Board Resolution and Officers'
Certificate complying with Section 3.1 hereof, be issued by means of an
electronic issuance system. Any such Security issuance instructions may specify
the name, address and taxpayer identification number of the Holder, the
principal amount and Maturity of the Security, the interest rate to be borne by
the Security and any other terms not inconsistent with such Board Resolution
and Officers' Certificate. Nothing in this Section 3.11 shall be construed as
prohibiting the Company from issuing Securities by any means not inconsistent
with the provisions of this Indenture.

SECTION 3.12  CUSIP Numbers.

            The Company in issuing the Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of redemption as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness of such
numbers either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be
affected by any defect in or omission of such numbers.  The Company will
promptly notify the Trustee of any change in the CUSIP numbers.


                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

SECTION 4.1  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 any right to receive
additional amounts, as provided in Section 10.4), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when:

                  Coupons appertaining to Bearer Securities surrendered for
                  exchange for Registered Securities and maturing after such
                  exchange, whose surrender is not required or has been waived
                  as provided in Section 3.5, (ii) Securities and Coupons which
                  have been destroyed, lost or stolen and which have been
                  replaced or paid as provided in Section 3.6, (iii) Coupons
                  appertaining to Securities called for redemption and maturing

                  Coupons for whose payment money has theretofore been

                  from such trust, as provided in Section 10.3) have been
                  delivered to the Trustee for cancellation; or

                  (B)  all such Securities and, in the case of (i) or (ii)
                  below, any Coupons appertaining thereto not theretofore

                          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, an
                          amount sufficient to pay and discharge the entire

Obligations has been deposited with or received by the Trustee.

SECTION 4.3  Company's Option to Effect Defeasance or Covenant Defeasance.

            If applicable to a particular series of Securities, the Company may

be, designated pursuant to Section 3.1 as being defeasible pursuant to such
Section 4.4 or 4.5, in accordance with any applicable requirements provided

SECTION 4.4  Discharge and Defeasance.

            If this Section 4.4 is specified, as contemplated by Section 3.1,

Company shall be deemed to have paid and discharged the entire indebtedness on
all the Outstanding Securities of any such series ("Defeasance"); and (ii) the
provisions of this Indenture as it relates to such Outstanding Securities shall
no longer be in effect (except as to the rights of Holders of Securities to

SECTION 4.5  Covenant Defeasance.

            If this Section 4.5 is specified, as contemplated by Section 3.1,
to be applicable to any series of Securities or any Securities of such series,
as the case may be, (1) the Company shall be released from its obligations
under Section 8.1(3) and Sections 10.4 through 10.8, inclusive, and any
covenants provided pursuant to Section 3.1(21), 9.1(2) or 9.1(6) for the
benefit of the Holders of such Securities that pursuant to the terms of such

terms of such Securities this Section 4.5 is applicable to any such event
specified in Section 5.1(9)) 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 4.6 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 5.1(4) and 5.1(9)), 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 4.6  Conditions to Defeasance or Covenant  Defeasance.

            The following shall be the conditions to the application of Section
4.4 or Section 4.5 to any applicable series of Securities or any Securities of
such series, as the case may be.

                  (1)  either

                  (A)  with respect to all Outstanding Securities of such

                  with reference to this Section 4.6, the Company has deposited
                  or caused to be deposited with the Trustee irrevocably (but
                  subject to the provisions of Section 4.2 and the last
                  paragraph of Section 10.3), as trust funds in trust,
                  specifically pledged as security for, and dedicated solely
                  to, the benefit of the Holders of such Securities, (X) lawful
                  money of the United States in an amount, or (Y) U.S.
                  Government Obligations which through the payment of interest
                  and principal in respect thereof in accordance with their

                  independent public accountants expressed in a written
                  certification thereof delivered to the Trustee, to pay and
                  discharge (i) the principal of (and premium, if any) and each
                  installment of principal of (and premium, if any) and
                  interest on such Securities at the Stated Maturity of such
                  principal or

                  installment of principal or interest or upon optional
                  redemption and (ii) any mandatory sinking fund payments or
                  analogous payments applicable to such Securities on the day
                  on which such payments are due and payable in accordance with
                  the terms of this Indenture and of such Securities; or

                  (B)  the Company has properly fulfilled such other means of
                  satisfaction and discharge as is specified, as contemplated
                  by Section 3.1, to be applicable to the Securities of such
                  series;

                  (2)  the Company has paid or caused to be paid all other sums
                  payable with respect to such Securities;

                  (3)  such deposit will not result in a breach or violation
                  of, or constitute a default under, this Indenture or any
                  other agreement or instrument to which the Company is a party
                  or by which it is bound;

                  (4)  no Event of Default or event which with the giving of
                  notice or lapse of time, or both, would become an Event of
                  Default with respect to such Securities shall have occurred
                  and be continuing on the date of such deposit and no Event of
                  Default under Section 5.1(5) or Section 5.1(6) or event which
                  with the giving of notice or lapse of time, or both, would
                  become an Event of Default under Section 5.1(5) or Section
                  5.1(6) shall have occurred and be continuing on the 91st day
                  after such date;

                  (5)  in the event of an election to have Section 4.4 apply to
                  any series of Securities, the Company has delivered to the
                  Trustee an Opinion of Counsel to the effect 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 Indenture there has been a change in applicable
                  Federal income tax law, in either case to the effect that,
                  and based thereon such Opinion of Counsel shall confirm that,
                  the Holders of Securities of such series will not recognize
                  income, 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 and in the
                  same manner and at the same times as would have been the case
                  if such deposit, defeasance and discharge had not occurred;

                  (6)  in the event of an election to have Section 4.5 apply to
                  any series of Securities, 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;

                  (7)  if the Securities of that series are then listed on any
                  domestic or foreign securities exchange, the Company shall
                  have delivered to the Trustee an Opinion of Counsel to the
                  effect that such deposit, defeasance and discharge will not
                  cause such Securities to be desisted; and

                  (8)  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
                  Defeasance or Covenant Defeasance with respect to such
                  Securities of any such series have been complied with and an
                  Opinion of Counsel to the effect that either (i) as a result
                  of such deposit and the related exercise of the Company's
                  option under this Article, registration is not required under
                  the Investment Company Act of 1940, as amended, by the
                  Company, the trust funds representing such deposit or the
                  Trustee or (ii) all necessary registrations under said Act
                  have been effected.

            Any deposits with the Trustee referred to in Section 4.6(1)(A)
above shall be irrevocable and shall be made under the terms of an escrow/trust
agreement in form and substance satisfactory to the Trustee. If any Outstanding
Securities of such series are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with
any mandatory sinking fund requirement, the applicable escrow trust agreement
shall provide therefor and the Company shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company.

            Upon Defeasance with respect to all the Securities of a series, the
terms and conditions of such Securities, including the terms and conditions
with respect thereto set forth in this Indenture, shall no longer be binding
upon, or applicable to, the Company; provided that the Company shall not be
discharged from any payment obligations in respect of Securities which are
deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law.

            Notwithstanding the cessation, termination and discharge of all
obligations, covenants and agreements (except as provided above in this Section
4.6) of the Company under this Indenture with respect to any series of
Securities, the obligations of the Company to the Trustee under Section 6.5,
and the obligations of the Trustee under Section 4.2 and the last paragraph of
Section 10.3 shall survive with respect to such series of 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 this
Section 4.6 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.

            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 4.1 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.

                  taking possession by a custodian, receiver, liquidation,
                  assignee, trustee, sequestrator or similar official of the
                  Company or of any substantial part of their property, or the
                  making by it of an assign-

                  ment 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

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

SECTION 5.2  Acceleration of Maturity; Rescission and Annulment.

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

            At any time after such a declaration of acceleration with respect
to Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of at least 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





                                       43
<PAGE>   52
                  solely by such declaration of acceleration, have been cured
                  or waived as provided in Section 5.13.

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

SECTION 5.3  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 of any series 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 of any series at the
                  Maturity thereof,

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

            If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon such Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon such
Securities, wherever situated.

            If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series and any Coupons appertaining thereto 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 5.4  Trustee May File Proofs of Claim.

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

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

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

and any custodian, receiver, assignee, trustee, liquidation, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities and Coupons to make such payments to the Trustee and,
in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities and Coupons, 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 6.7.

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

SECTION 5.5  Trustee May Enforce Claims Without Possession of Securities or
             Coupons.

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





                                       45
<PAGE>   54
for the ratable benefit of the Holders of the Securities and Coupons in respect
of which such judgment has been recovered.

SECTION 5.6  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 or Coupons, or both,
as the case may be, and the notation thereon of the payment if only partially
paid and upon surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
                  Section 6.7;

                  SECOND: To the payment of the amounts then due and unpaid for
                  principal of and any premium and interest on the Securities
                  and Coupons 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 and Coupons for principal and any
                  premium and interest, respectively; and

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

SECTION 5.7  Limitation on Suits.

            No Holder of any Security of any series or any related Coupons
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





                                       46
<PAGE>   55
                  (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 5.8  Unconditional Right of Holders to Receive Principal, Premium and
             Interest.

            Notwithstanding any other provision in this Indenture, but subject
to Article XV of this Indenture, the Holder of any Security or Coupon shall
have the right, which is absolute and unconditional, to receive payment of the
principal of and any premium and (subject to Section 3.7) interest on such
Security, and any additional amounts contemplated by Section 10.4 in respect of
such Security or payment of such Coupon on the Stated Maturity or Maturities
expressed in such Security or Coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

SECTION 5.9  Restoration of Rights and Remedies.

            If the Trustee or any Holder of a Security or Coupon has instituted
any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and Coupons 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 5.10  Rights and Remedies Cumulative.

            Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or Coupons in the
last paragraph of Section 3.6, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders of Securities or Coupons is intended
to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

SECTION 5.11  Delay or Omission Not Waiver.





                                       47
<PAGE>   56
            No delay or omission of the Trustee or of any Holder of any
Security or Coupon to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein. Every right and remedy given
by this Article or by law to the Trustee or to the Holders of Securities or
Coupons may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or Coupons, as the
case may be.

SECTION 5.12  Control by Holders of Securities.

            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

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

SECTION 5.13  Waiver of Past Defaults.

            The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto waive any past
default hereunder with respect to the Securities of such series and its
consequences, except a default

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

                  (2)  in respect of a covenant or provision hereof which under
                  Article IX cannot be modified or amended without the consent
                  of the Holder of each Outstanding Security of 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 5.14  Undertaking for Costs.

            All parties to this Indenture agree, and each Holder of any
Security or Coupon by his acceptance thereof shall be deemed to have agreed,
that any court may in its discretion re quire, in any suit for the enforcement
of any right or remedy under this Indenture, or in any





                                       48
<PAGE>   57
suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees and expenses, against
any party litigant in such suit, having due regard to the merits and good faith
of the claims or defenses made by such party litigant; but the provisions of
this Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
of any Security or Coupon for the enforcement of the payment of the principal
of or any premium or interest on any Security or the payment of any Coupon on
or after the Stated Maturity or Maturities expressed in such Security or Coupon
(or, in the case of redemption, on or after the Redemption Date).

SECTION 5.15  Waiver of Stay or Extension Laws.

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

                                   ARTICLE VI

                                  THE TRUSTEE


SECTION 6.1  Duties and Responsibilities of the Trustee; During Default; Prior
             to Default.

            With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a particular series and after the curing or
waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture.  In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived), the Trustee shall exercise with respect to such series of Securities
such of the rights and powers vested in it by this Indenture, and shall use the
same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.





                                       49
<PAGE>   58
            No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own wilful misconduct, except that:

            (a)   prior to the occurrence of an Event of Default with respect
to the Securities of any series and after the curing or waiving of all such
Events of Default with respect to such series which may have occurred:

                  (i)  the duties and obligations of the Trustee with respect
                  to the Securities of any series shall be determined solely by
                  the express provisions of this Indenture, and the Trustee
                  shall not be liable except for the performance of such duties
                  and obligations as are specifically set forth in this
                  Indenture, and no implied covenants or obligations shall be
                  read into this Indenture against the Trustee; and

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

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

            (c)  the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with the
direction of the Holders pursuant to Section 5.12 relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred upon the Trustee, under this
Indenture.

            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.


SECTION 6.2  Certain Rights of Trustee.

            Subject to the provisions of the Trust Indenture Act:





                                       50
<PAGE>   59
                  (a)  the Trustee may rely and shall be protected in acting or
                  refraining from acting upon any resolution, certificate,
                  statement, instrument, opinion, report, notice, request,
                  direction, consent, order, bond, debenture, note, Coupon,
                  other evidence of indebtedness or other paper or document
                  believed by it to be genuine and to have been signed or
                  presented by the proper party or parties;

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

                  (c)  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;

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

                  (e)  the Trustee shall be under no obligation to exercise any
                  of the rights or powers vested in it by this Indenture at the
                  request or direction of any of the Holders of Securities of
                  any series or any related Coupons 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;

                  (f)  the Trustee shall not be bound to make any investigation
                  into the facts or matters stated in any resolution,
                  certificate, statement, instrument, opinion, report, notice,
                  request, direction, consent, order, bond, debenture, note,
                  Coupon, 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

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

                                       51
<PAGE>   60
            The recitals contained herein and in the Securities (except the
Trustee's certificate of authentication) and in any Coupons shall be taken as
the statements of the Company, and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or Coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in its
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate. The Trustee or any Authenticating Agent shall not be accountable for
the use or application by the Company of Securities or the proceeds thereof.

SECTION 6.4  May Hold Securities.

            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 Coupons and,
subject to Section 6.8 and 6.10, 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.

SECTION 6.5  Money Held in Trust.

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

SECTION 6.6  Compensation and Reimbursement..

            The Company agrees:

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

                  (2)  except as otherwise expressly provided herein, to
                  reimburse the Trustee or any predecessor Trustee upon its
                  request for all reasonable expenses, disbursements and
                  advances incurred or made by the Trustee in accordance with
                  any provision of this Indenture (including the 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 and any predecessor Trustee
                  for, and to hold it harmless against, any and all loss,
                  damage, claim, liability or expense, including taxes (other
                  than taxes based on the income of the Trustee) incurred
                  without negligence or bad faith on its part, arising out of
                  or in connection with the acceptance





                                       52
<PAGE>   61
                  or administration of the trust or trusts hereunder, including
                  the costs and expenses of defending itself against any claim
                  or liability in connection with the exercise or performance
                  of any of its powers or duties hereunder.

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.1(7) or Section 5.1(8), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or
other similar law.

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

SECTION 6.7  Resignation and Removal; Appointment of Successor.

            (a)  No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.8.

            (b)  The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If the instrument of acceptance by a successor Trustee required by
Section 6.8 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.

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

            (d)  If at any time:

                  (1)  the Trustee shall fail to comply with Section 310(b) of
                  the Trust Indenture Act after written request therefor by the
                  Company or by any Holder of a Security who has been a bona
                  fide Holder of a Security for at least six months, or

                  (2)  the Trustee shall cease to be eligible under Section 6.9
                  and Section 310(a) of the Trust Indenture Act 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, (i) the
                  Company by a Board Resolution may remove the Trustee with





                                       53
<PAGE>   62
                  respect to all Securities, or (ii) subject to Section 5.14
                  any Holder of a Security who has been a bona fide Holder of a
                  Security for at least six months may, on behalf of himself
                  and all others similarly situated, petition any court of
                  competent jurisdiction for the removal of the Trustee with
                  respect to all Securities and the appointment of a successor
                  Trustee or Trustees.

            (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause,
with respect to the Securities of one or more series, the Company, by 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 6.8. 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
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 6.8, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders of Securities of
that series and accepted appointment in the manner required by Section 6.8, any
Holder of a Security who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

            (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
in the manner provided in Section 1.6. 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 6.8  Acceptance of Appointment by Successor.

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





                                       54
<PAGE>   63
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.

            (b)  In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such
appointment and which (l) 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 as co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

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

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

SECTION 6.9  Disqualification; Conflicting Interests.

            If the Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.





                                       55
<PAGE>   64
SECTION 6.10  Corporate Trustee Required; Eligibility.

            There shall be at all times a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000.  If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, 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 shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereunder specified in this
Article.

SECTION 6.11  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 6.12  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 6.13  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 au thenticate Securities of such series issued upon
original issue or upon exchange, registration of transfer or partial redemption
thereof or pursuant to Section 3.6, 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 accept-





                                       56
<PAGE>   65
able to the Company. 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 such 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 such 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 promptly give notice
of such appointment to all Holders of Securities pursuant to Section 1.6. 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 Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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

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

                          As Trustee

                          Authorized Signatory


            If all of the Securities of a series may not be originally issued
at one time, and if the Company has an Affiliate eligible to be appointed as an
Authenticating Agent hereunder or the Trustee does not have an office capable
of authenticating Securities upon original issuance located in a Place of
Payment where the Company wishes to have Securities of such series
authenticated upon original issuance, the Trustee, if so requested by the
Company in writing (which writing need not comply with Section 1.2 and need not
be accompanied by an Opinion of Counsel), shall appoint in accordance with this
Section an Authenticating Agent (which if so requested by the Company, shall be
such Affiliate of the Company) having an office in a Place of Payment
designated by the Company with respect to such series of Securities.

SECTION 6.14.  Notice of Defaults.

            If a default occurs hereunder with respect to Securities of any
series, the Trustee shall, within 90 days of such occurrence,  give the Holders
of Securities of such series notice of such default known to it 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 5.1(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.


                                  ARTICLE VII

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 7.1  Preservation of Information; Communications to Holders.

            (a)  The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders of Securities (i)
contained in the most recent list furnished to the Trustee as provided in
Section 312(a) of the Trust Indenture Act, (ii) received by the Trustee in its
capacity as Security Registrar and (iii) filed with it within the two preceding
years pursuant to Section 313(c)(2) of the Trust Indenture Act. The Trustee may
(i) destroy any list furnished to it as provided in Section 312(a) of the Trust
Indenture Act upon receipt





                                       58
<PAGE>   67
of a new list so furnished, (ii) destroy any information received by it as
Paying Agent (if so acting) hereunder upon delivering to itself as Trustee, not
earlier than March 20 or September 20 of each year, a list containing the names
and addresses of the Holders of Securities obtained from such information since
the delivery of the next previous list, if any, (iii) destroy any list
delivered to itself as Trustee which was compiled from information received by
it as Paying Agent (if so acting) hereunder upon the receipt of a new list so
delivered and (iv) destroy not earlier than two years after filing, any
information filed with it pursuant to Section 313(c)(2) of the Trust Indenture
Act.  For purposes of Section 312(a) of the Trust Indenture Act, the term
"stated intervals" shall mean January 15 and July 15.

            (b)  If three or more Holders of Securities (herein referred to as
"applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security for a period of
at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other Holders
of Securities with respect to their rights under this Indenture or under the
Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee
shall, within five business days after the receipt of such application, at its
election, either

                  (i)  afford such applicants access to the information
                  preserved at the time by the Trustee in accordance with
                  Section 7.1(a), or

                  (ii)  inform such applicants as to the approximate number of
                  Holders of Securities whose names and addresses appear in the
                  information preserved at the time by the Trustee in
                  accordance with Section 7.1(a), and as to the approximate
                  cost of mailing to such Holders the form of proxy or other
                  communication, if any, specified in such application.

            If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of Securities whose name and address appears in
the information preserved at the time by the Trustee in accordance with Section
7.1(a) a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment of the
reasonable expenses of mailing, unless within five days after such tender the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interest of the Holders of Securities or would be in violation of applicable
law. Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in
the written statement so filed, shall enter an order refusing to sustain any of
such objections or if after the entry of an order sustaining one or more of
such objections, the Commission shall find, after notice and opportunity for
hearing that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such material to all such
Holders of Securities





                                       59
<PAGE>   68
with reasonable promptness after the entry of such order and the renewal of

                  the amount of the principal of an Original Issue Discount
                  Security that would be due and payable upon a declaration of
                  acceleration of the Maturity thereof pursuant to Section 5.2
                  or change the coin or currency in which any Security or any
                  premium or interest thereon is payable, or impair the right
                  to institute suit for the enforcement of any such payment on

                  redemption, on or after the Redemption Date), or

                  (2)  reduce the percentage in principal amount of the

                  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 of a Security or Coupon with respect to changes
                  in the references to "the Trustee" and concomitant changes in

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

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.


SECTION 9.7  Subordination Unimpaired.

SECTION 10.2  Maintenance of Office or Agency.

            If Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for such series
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, exchange, or 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. If Securities of a series are issuable as Bearer
Securities, the Company will maintain (A) in The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment, where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may
be surrendered for conversion or exchange, where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served and where Bearer Securities of that series and related Coupons may be
presented or surrendered for payment in the circumstances described in the
following paragraph (and not otherwise), (B) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series which is located
outside the United States, an office or agency where Securities of that series
and related Coupons may be presented and surrendered for payment (including
payment of any additional amounts payable on Securities of that series pursuant
to Section 10.4); provided, however, that if the Securities of that series are

the Luxembourg Stock Exchange or any other stock exchange located outside the
United States and such stock exchange shall so require, the Company will
maintain a Paying Agent for the Securities of that series in London, Luxembourg
or any other required city located outside the United States, as the case may
be, so long as the Securities of that series are listed on such exchange, and
(C) subject to any laws or regulations applicable thereto in a Place of Payment
for that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for conversion or
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt notice to the Trustee and to the Holders as provided in Sections
1.5 and 1.6, respectively, of the location and any change in the location, of
any such office or agency. If at any time the Company shall fail to maintain
any such required office or agency in respect of any series of Securities or
shall fail to furnish the Trustee with the address thereof, such presentations
and surrenders of Securities of that series may be made and notices and demands
may be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related Coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Bearer Securities of that series pursuant to Section 10.4) at the office of the
Trustee for such series located outside the United States, and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands.

            No payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in





                                       67
<PAGE>   76
the United States or by transfer to any account maintained with a bank located
in the United States; provided, however, that if the Securities of a series are
denominated and payable in Dollars, payment of principal of and any premium and
interest on any Bearer Security (including any additional amounts payable on
Securities of such series pursuant to Section 10.4) shall be made at the office
of the Company's Paying Agent in The City of New York, if (but only if) payment
in Dollars of the full amount of such principal, premium, interest or
additional amounts, as the case may be, at all offices or agencies outside the
United States maintained for the purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

            The Company may 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 accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to
the Trustee and the Holders of any such designation or rescission and of any
change in the location of any such other office or agency.

SECTION 10.3  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 and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure to act.

            Whenever the Company shall have one or more Paying Agents for any
series of Securities it will, prior to each due date of the principal of and
any premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay the principal and any premium or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to act.

            The Company will cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

                  (1)  hold all sums held by it for the payment of the
                  principal of and any premium or interest on Securities of
                  that series in trust for the benefit of the Persons entitled
                  thereto until such sums shall be paid to such Persons or
                  otherwise disposed of as herein provided;





                                       68
<PAGE>   77
                  (2)  give the Trustee notice of any default by the Company
                  (or any other obligor upon the Securities of that series) in
                  the making of any payment of principal of and any premium or
                  interest on the Securities of that series; and

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

            The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such 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 and any
premium or interest on any Security of any series and remaining unclaimed for
two years after such principal and any 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 or any Coupon appertaining thereto 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 an Authorized Newspaper 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 10.4  Additional Amounts.

            If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any Coupon appertaining thereto additional amounts as provided therein.
Whenever in this Indenture there is mentioned, in any context, the payment of
the principal of or any premium or interest on, or in respect of any Security
of any series or payment of any related Coupon or the net proceeds received on
the sale or exchange of any Security of any series, such mention shall be
deemed to include mention of the payment of additional amounts provided for in
this Section to the extent that, in such context additional amounts are, were
or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of additional amounts (if
applicable) in any provisions hereof shall not be construed as excluding
additional amounts in those provisions hereof where such express mention is not
made.





                                       69
<PAGE>   78
            If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
Coupons who are United States Aliens without withholding for or on account of
any tax assessment or other governmental charge described in the Securities of
that series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be
withheld on such payments to such Holders of Securities or Coupons and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by this Section. The Company covenants to indemnify the Trustee and
any Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or willful misconduct on their
part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this
Section.

SECTION 10.5  Existence.

            Subject to Article VIII, the Company will do or cause to be done
all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the
loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 10.6  Purchase of Securities by Company or Subsidiary.

            If and so long as the Securities of a series are listed on The
Stock Exchange of the United Kingdom and the Republic of Ireland and such stock
exchange shall so require, the Company will not, and will not permit any of its
Subsidiaries to, purchase any Securities of that series by private treaty at a
price (exclusive of expenses and accrued interest) which exceeds 120% of the
mean of the nominal quotations of the Securities of that series as shown in The
Stock Exchange Daily Official List for the last trading day preceding the date
of purchase.

SECTION 10.7  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 signed by its principal executive officer, principal
financial officer or principal accounting officer stating





                                       70
<PAGE>   79
whether or not to the best knowledge of the signer thereof the Company is in
default in the performance and observance of any of the terms, provisions and
conditions of this Indenture, and if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which they
may have knowledge.

SECTION 10.8      Calculation of Original Issue Discount.

            The Company shall file with the Trustee promptly at the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities
as of the end of such year.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

SECTION 11.1  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 3.1 for Securities of any
series) in accordance with this Article.

SECTION 11.2  Election to Redeem; Notice to Trustee.

            The election of the Company to redeem any Securities shall be
evidenced by an Officers' Certificate. In the case of any redemption at the
election of the Company, 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 and of
the principal amount of Securities of such series to be redeemed. In the case
of any redemption of Securities (i) prior to the expiration of any restriction
on such redemption provided in the terms of such Securities or elsewhere in
this Indenture, or (ii) pursuant to an election of the Company which is subject
to a condition specified in the terms of such Securities, the Company shall
furnish the Trustee with an Officers' Certificate evidencing compliance with
such restriction or condition.

SECTION 11.3  Selection by Trustee of Securities to Be Redeemed.

            If less than all the Securities of any series and of like tenor are
to be redeemed, the particular Securities to be redeemed shall be selected not
more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and of like tenor not previously called
for redemption, by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection, for redemption of portions (equal to
the minimum authorized denomination for Securities of that series or any
integral multiple thereof) of the principal amount of Registered Securities of
such series of a denomination





                                       71
<PAGE>   80
larger than the minimum authorized denomination for Securities of that series.
If so specified in the Securities of a series, partial redemptions must be in
an amount not less than $1,000,000 principal amount of Securities.

            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
(or portions thereof) 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. In any case where more than one Security is
registered in the same name, the Trustee in its discretion may treat the
aggregate principal amount so registered as if it were represented by one
Security.

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

            For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any 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 11.4  Notice of Redemption.

            Notice of redemption shall be given in the manner provided in
Section 1.6 to the Holders of Securities to be redeemed not less than 30 nor
more than 60 days prior to the Redemption Date.

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

            All notices of redemption shall state:

                  (1)  the Redemption Date;

                  (2)  the Redemption Price;

                  (3)  if less than all the Outstanding Securities of any
                  series are to be redeemed, the identification (and, in the
                  case of partial redemption, the principal amounts) of the
                  particular Securities to be redeemed, and a statement to the
                  effect that on or after the Redemption Date upon surrender of
                  such Security a new Security in the principal amount equal to
                  the unredeemed portion will be issued;





                                       72
<PAGE>   81
                  (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 such Securities, together in
                  the case of Bearer Securities with all Coupons appertaining
                  thereto, if any maturing after the Redemption Date, are to be
                  surrendered for payment of the Redemption Price;

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

                  (7)  if applicable, the conversion rate or price, the date on
                  which the right to convert the Securities to be redeemed will
                  terminate and the place or places where such Securities may
                  be surrendered for conversion.

            A notice of redemption published as contemplated by Section 1.6
need not identify particular Registered Securities to be redeemed.

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

SECTION 11.5  Deposit of Redemption Price.

            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 10.3) 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 into Common
Stock of the Company, any money deposited with the Trustee or with any Paying
Agent or so segregated and held in trust for the redemption of such Security
shall (subject to any right of the Holder of such Security or any Predecessor
Security to receive interest as provided in the last paragraph of Section 3.7)
be paid to the Company upon Company Request or, if then held by the Company,
shall be discharged from such trust.

SECTION 11.6  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 and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice together with all Coupons, if any,
appertaining thereto maturing after the Redemp-





                                       73
<PAGE>   82
tion Date, such Security shall be paid by the Company at the Redemption Price
together with accrued interest to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section
10.2) and, unless otherwise specified as contemplated by Section 3.1, only upon
presentation and surrender of Coupons for such interest; and provided, further,
that, unless otherwise specified as contemplated by Section 3.1, installments
of interest on Registered Securities whose Stated Maturity is on or prior to
the Redemption Date shall be payable to the Holders of such Securities or one
or more Predecessor Securities, registered as such at the close of business on
the relevant Record Dates according to their terms and the provisions of
Section 3.7.

            If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such
missing Coupon or Coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless. If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
Coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by Coupons shall be payable only
at an office or agency located outside the United States (except as otherwise
provided in Section 10.2) and unless otherwise specified as contemplated by
Section 3.1 only upon presentation and surrender of those Coupons.

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

SECTION 11.7  Securities Redeemed in Part.

            Any Registered 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 his attorney duly authorized in writing), and the Company shall
execute, and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series and of like tenor of any authorized denomination as requested by
such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                  ARTICLE XII

                                 SINKING FUNDS

SECTION 12.1  Applicability of Article.

            The provisions of this Article shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise specified
as contemplated by Section 3.1 for Securities of such series.

            The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 12.2. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

SECTION 12.2  Satisfaction of Sinking Fund Payments with Securities.

            The Company (1) may deliver Outstanding Securities of a series
(other than any previously called for redemption), together in the case of any
Bearer Securities of such series with all unmatured Coupons appertaining
thereto, and (2) 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 the Securities
of such series required to be made pursuant to the terms of such Securities, as
provided for by the terms of such series; provided that such Securities have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount
of such sinking fund payment shall be reduced accordingly.

SECTION 12.3  Redemption of Securities for Sinking Fund.

            Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 45 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in





                                       75
<PAGE>   84
Section 11.3 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 11.4.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Sections 11.6 and 11.7.


                                  ARTICLE XIII

                       MEETINGS OF HOLDERS OF SECURITIES

SECTION 13.1  Purposes for Which Meetings May be Called.

            If Securities of a series are issuable as Bearer Securities, a
meeting of Holders of Securities of such series may be called at any time and
from time to time pursuant to this Article to make, give or take any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

SECTION 13.2  Call, Notice and Place of Meetings.

            (a)  The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 13.1, to be held
at such time and at such place in the Borough of Manhattan, The City of New
York, or in London as the Trustee shall determine. Notice of every meeting of
Holders of Securities of any series, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such
meeting, shall be given, in the manner provided in Section 1.6, not less than
21 nor more than 180 days prior to the date fixed for the meeting (or, in the
case of a meeting of Hold ers with respect to Securities of a series all or
part of which are represented by a Book-Entry Security, not less than 20 nor
more than 40 days).

            (b)  In case at any time the Company, pursuant to a Board
Resolution, or the Holders of at least 25% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified
in Section 13.1, by written request setting forth in reasonable detail the
action proposed to be taken at the meeting, and the Trustee shall not have made
the first publication of the notice of such meeting within 21 days after
receipt of such request or shall not thereafter proceed to cause the meeting to
be held as provided herein, then the Company or the Holders of Securities of
such series in the amount above specified, as the case may be, may determine
the time and the place in the Borough of Manhattan, The City of New York or in
London for such meeting and may call such meeting for such purposes by giving
notice thereof as provided in subsection (a) of this Section.

SECTION 13.3  Persons Entitled to Vote at Meetings.

            Upon the calling of a meeting of Holders with respect to the
Securities of a series all or part of which are represented by a Book-Entry
Security, a record date shall be established for determining Holders of
Outstanding Securities of such series entitled to vote at such meeting, which
record date shall be the close of business on the day the notice of the meeting
of Holders is given in accordance with Section 13.2. The Holders on such record
date, and their designated proxies, and only such Persons, shall be entitled to
vote at any meeting of Holders. To be entitled to vote at any meeting of
Holders a Person shall (a) be a Holder of one or more Outstanding Securities or
(b) be a Person appointed by an instrument in writing as proxy by a Holder of
one or more Securities; provided, however, that in the case of any meeting of
Holders with respect to the Securities of a series all or part of which are
represented by a Book-Entry Security, only Holders, or their designated
proxies, of record on the record date established pursuant to Section 13.3
hereof shall be entitled to vote at such meeting. The only Persons who shall be
entitled to be present or to speak at any meeting of Holders shall be the
Persons entitled to vote at such meeting and their counsel and any
representatives of the Trustee and its counsel and any representatives of the
Company and its counsel.

SECTION 13.4  Quorum; Action.

            The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of a specified
percentage in aggregate principal amount of Outstanding Securities of a series
that is less or greater than a majority in principal amount of the Outstanding
Securities of a series, then, with respect to such action (and only such
action) the Persons entitled to vote such lesser or greater percentage in
principal amount of the Outstanding Securities of such series shall constitute
a quorum. In the absence of a quorum within 30 minutes of the time appointed
for any such meeting, the meeting shall, if convened at the request of Holders
of Securities of such series, be dissolved. In any other case the meeting may
be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may
be further adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such adjourned meeting.
Notice of the reconvening of any adjourned meeting shall be given as provided
in Section 13.2 (a), except that such notice need be given only once not less
than five days prior to the date on which the meeting is scheduled to be
reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage, as provided above, of the principal amount of the
outstanding Securities of such series which shall constitute a quorum.
Notwithstanding the foregoing, no meeting of Holders with respect to Securities
of any Series which is represented in whole or in part by a Book-Entry
Security, shall be adjourned to a date more than 90 days after the record date
for such meeting unless the Trustee shall send out a new notice of





                                       77
<PAGE>   86
meeting and establish, in accordance with Section 13.3, a new record date for
Holders entitled to vote at such meeting.

            Except as limited by the proviso to Section 9.2, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum
is present as aforesaid may be adopted by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2 any
resolution with respect to any consent or waiver which this Indenture expressly
provides may be given by the Holders of a specified percentage in aggregate
principal amount of Outstanding Securities of a series that is less or greater
than a majority in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly convened and at which
a quorum is present as aforesaid only by the affirmative vote of the Holders of
such specified percentage in principal amount of the Outstanding Securities of
that series.

            Any resolution passed or decision taken at any meeting of Holders
of Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related
Coupons, whether or not present or represented at the meeting.

SECTION 13.5  Determination of Voting Rights; Conduct and Adjournment of
              Meetings.

            (a)  Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of a series in regard to proof of the holding
of Securities of such series and of the appointment of proxies and in regard to
the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appro priate. Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 1.4 and the appointment of any proxy shall be proved in the manner
specified in Section 1.4 or by having the signature of the person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized
by Section 1.4 to certify to the holding of Bearer Securities. Such regulations
may provide that written instruments appointing proxies, regular on their face,
may be presumed valid and genuine without the proof specified in Section 1.4 or
other proof.

            (b)  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 13.2(b), in
which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.





                                       78
<PAGE>   87
            (c)  At any meeting each Holder of a Security of such series or
proxy shall be entitled to one vote for each $ 1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

            (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 13.2 at which a quorum is present may be adjourned from
time to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 13.6  Counting Votes and Recording Action of Meetings.

            The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 13.2 and, if
applicable, Section 13.4. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                                  ARTICLE XIV

                            CONVERSION OF SECURITIES



SECTION 14.1  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 3.1 for the Securities of such series. The terms and provisions
applicable to the conversion of Securities of any series into securities of the
Company (other





                                       79
<PAGE>   88
than Common Stock) shall, if applicable, be set forth in an Officers'
Certificate or established in one or more indentures supplemental hereto, prior
to the issuance of Securities of such series in accordance with Section 3.1.

SECTION 14.2  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
10.2, accompanied by written notice to the Company 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 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 such period) 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 3.7 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 3.1, 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





                                       80
<PAGE>   89
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 3.7, no payment or adjustment shall be made upon any
conversion on account of any interest accrued on the Securities surrendered for
conversion or on account of any dividends on the Common Stock 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 14.3  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 14.3, 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, on
the basis of the last reported sale price regular way on such exchange 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 admit ted to unlisted trading privileges on a national securities exchange,
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 New York
Stock Exchange, or if the Common Stock is not traded on the New York Stock
Exchange, on the principal exchange or market on which the Common Stock is
traded or quoted.

SECTION 14.4  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, reclassification, 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.





                                       81
<PAGE>   90
            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 10.2 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 14.5  Notice of Certain Corporate Actions.

            In case:

                  (a)  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); or

                  (b)  the Company shall authorize the granting to 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

                  (c)  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

                  (d)  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
(a) or (b) 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





                                       82
<PAGE>   91
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 14.6  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 or
treasury shares, 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 14.7  Payment of Certain Taxes upon Conversion.

            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 14.8  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 14.9  Effect of Consolidation or Merger on Conversion Privilege.

            In case of any consolidation of the Company with, or merger of the
Company into or with any other Person, or in case of any sale of all or
substantially all of the assets of the Company, the Company or the Person
formed by such consolidation or the Person into which the Company shall have
been merged or the Person which shall have acquired such assets, as the case
may be, shall execute and deliver to the Trustee a supplemental indenture
providing that the Holder of each Security then outstanding of any series that
is convertible into Common Stock of the Company shall have the right, which
right shall be the exclusive conversion right thereafter available to said
Holder (until the expiration of the conversion right of such Security), to
convert such Security into the kind and amount of shares of stock or other
securities or property (including cash) receivable upon such consolidation,
merger or sale 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 or sale, subject to compliance with the other
provisions of this Indenture, such Security and such supplemental indenture.
Such supplemental indenture shall provide for adjustments which shall be as





                                       83
<PAGE>   92
nearly equivalent as may be practicable to the adjustments provided for in such
Security. The above provisions of this Section shall similarly apply to
successive consolidations, mergers or sales. It is expressly agreed and
understood that anything in this Indenture to the contrary notwithstanding, if,
pursuant to such merger, consolidation or sale, holders of outstanding shares
of Common Stock of the Company do not receive shares of common stock of the
surviving corporation but receive other securities, cash or other property or
any combination thereof, Holders of Securities shall not have the right to
thereafter convert their Securities into common stock of the surviving
corporation or the corporation which shall have acquired such assets, but
rather, shall have the right upon such conversion to receive the other
securities, cash or other property receivable by a holder of the number of
shares of Common Stock of the Company into which the Securities held by such
holder might have been converted immediately prior to such consolidation,
merger or sale, all as more fully provided in the first sentence of this
Section 14.9. Anything in this Section 14.9 to the contrary notwithstanding,
the provisions of this Section 14.9 shall not apply to a merger or
consolidation of another corporation with or into the Company pursuant to which
both of the following conditions are applicable: (i) the Company is the
surviving corporation and (ii) the outstanding shares of Common Stock of the
Company are not changed or converted into any other securities or property
(including cash) or changed in number or character or reclassified pursuant to
the terms of such merger or consolidation.

            As evidence of the kind and amount of shares of stock or other
securities or property (including cash) into which Securities may properly be
convertible after any such consolidation, merger or sale, or as to the
appropriate adjustments of the conversion prices appli cable with respect
thereto, the Trustee shall be furnished with and may accept the certificate or
opinion of an independent certified public accountant with respect thereto;
and, in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely thereon, and shall not be responsible or accountable to any
Holder of Securities for any provision in conformity therewith or approved by
such independent certified accountant which may be contained in said
supplemental indenture.

SECTION 14.10  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.
Neither the Trustee nor any conversion agent shall be responsible for any





                                       84
<PAGE>   93
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 XIV 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.
All Securities delivered for conversion shall be delivered to the Trustee to be
cancelled by or at the direction of the Trustee, which shall dispose of the
same as provided in Section 3.9.

SECTION 14.11  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 funds deposited for the sinking fund
referred to in Article III hereof) and which shall not be required for such
purposes because of the conversion of such Securities as provided in this
Article XIV shall after such conversion be repaid to the Company by the Trustee
upon the Company's written request.

                                   ARTICLE XV

                          SUBORDINATION OF SECURITIES

SECTION 15.1    Securities Subordinate to Senior Debt.

                  The Company covenants and agrees, and each Holder of a
Security (for purposes of this Article XV, Security shall include any Coupons
appertaining thereto), by his acceptance thereof, likewise covenants and
agrees, that, to the extent and in the manner hereinafter set forth in this
Article, the indebtedness represented by the Securities and the payment of the
principal of (and premium, if any) and interest on each and all of the
Securities are hereby expressly made subordinate in right of payment to the
prior payment in full of all Senior Debt.

SECTION 15.2      Payment Over of Proceeds Upon Dissolution, Etc.

            In the event (a) of any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) of any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c)  that, subject to the
provisions of Section 15.3, (i) a default shall have occurred with respect to
the payment of principal of or interest on or other monetary amounts due and
payable on any Senior Debt, or (ii) there shall have occurred an event of
default (other than a default in the payment of principal or interest





                                       85
<PAGE>   94
or other monetary amounts due and payable) in respect of any Senior Debt, as
defined therein or in the instrument under which the same is outstanding,
permitting the holder or holders thereof to accelerate the maturity thereof
(with notice or lapse of time or both), and such event of default shall have
continued beyond the period of grace, if any, in respect thereof, and, in the
cases of subclauses (i) and (ii) of this clause (c), such default or event of
default shall not have been cured or waived or shall not have ceased to exist,
or (d) that the principal of and accrued interest on the Securities of any
series shall have been declared due and payable pursuant to Section 5.2 and
such declaration shall not have been rescinded and annulled as provided in
Section 5.2 then:

                  (1) the holders of all Senior Debt shall first be entitled to
            receive payment of the full amount due thereon, or provision shall
            be made for such payment in money or money's worth, before the
            Holders of any of the Securities or Coupons are entitled to receive
            a payment on account of the principal of or interest on the
            indebtedness evidenced by the Securities or of the Coupons,
            including, without limitation, any payments made pursuant to
            Article XI, and

                  (2) any payment by, or distribution of assets of, the Company
            of any kind or character, whether in cash, property or securities,
            to which the Holders of any of the Securities or Coupons or the
            Trustee would be entitled except for the provisions of this Article
            XV shall be paid or delivered by the person making such payment or
            distribution, whether a trustee in bankruptcy, a receiver or
            liquidating trustee or otherwise, directly to the holders of such
            Senior Debt or their representative or representatives or to the
            trustee or trustees under any indenture under which any instruments
            evidencing any of such Senior Debt may have been issued, ratably
            according to the aggregate amounts remaining unpaid on account of
            such Senior Debt held or represented by each, to the extent
            necessary to make payment in full of all Senior Debt remaining
            unpaid after giving effect to any concurrent payment or
            distribution (or provision therefor) to the holders of such Senior
            Debt, before any payment or distribution is made to the holders of
            the indebtedness evidenced by the Securities or Coupons or to the
            Trustee under this Indenture.

            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, including any such payment or
distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Debt is paid in full or payment thereof provided
for, and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, 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.  Any taxes that have been with-





                                       86
<PAGE>   95
held or deducted from any payment or distribution in respect of the Securities,
or any taxes that ought to have been withheld or deducted from any such payment
or distribution that have been remitted to the relevant taxing authority, shall
not be considered to be an amount that the Trustee or the Holder of any
Security receives for purposes of this Section.

            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
VIII shall not be deemed a dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of
assets and liabilities of the Company for the purposes of this Section if the
Person formed by such consolidation or into which the Company is merged or the
Person which acquires by conveyance or transfer such properties and assets
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 VIII.

            Notwithstanding the foregoing, at any time after the 91st day
following the date of deposit of cash or, in the case of Securities payable
only in Dollars, U.S. Government Obligations pursuant to Section 4.4 or 4.5
(provided all other conditions set out in such Sections and Section 4.6 shall
have been satisfied) the funds so deposited and any interest thereon will not
be subject to any rights of holders of Senior Debt including, without
limitation, those arising under this Article Fifteen.

SECTION 15.3      Disputes with Holders of Certain Senior Debt.

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





                                       87
<PAGE>   96
be prosecuting an appeal or other proceeding for review and a stay of execution
shall have been obtained pending such appeal or review.


SECTION 15.4      Payment Permitted in Certain Situations.

            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, assignment for the benefit of creditors or under the conditions
described in Section 14.2, from making payments at any time of principal of
(and premium, if any) or interest on the Securities, or (b) the application by
the Trustee of any money deposited with it hereunder to the payment of or on
account of the principal of (and premium, if any) or interest on the 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 15.5      Subrogation to Rights of Holders of Senior Debt.

            Subject to the payment in full of all Senior Debt or the provision
for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Debt, the Holders of the Securities shall
be subrogated to the extent of the payments or distributions made to the
holders of such Senior Debt pursuant to the provisions of this Article (equally
and ratably with the holders of indebtedness of the Company which by its
express terms is subordinated to indebtedness of the Company to substantially
the same extent as the Securities are subordinated to the Senior Debt and is
entitled to like rights of subrogation) 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 premium,
if any) and interest on the Securities shall be paid in full.  For purposes of
such subrogation, no payments or distributions to the holders of the Senior
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 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 15.6      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





                                       88
<PAGE>   97
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 premium, if any) and interest
on the Securities as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other
than the holders of Senior 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 15.7      Trustee to Effectuate Subordination.

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


SECTION 15.8      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 deal with 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>   98
SECTION 15.9      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 therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 6.1, shall be entitled in all respects to assume that no such facts
exist, provided, however, that if the Trustee shall not have received, at least
three Business Days prior to the date upon which by the terms hereof any such
money may become payable for any purpose, the notice with respect to such money
provided for in this Section 15.9, then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money
was received and shall not be affected by any notice to the contrary which may
be received by it within three Business Days prior to such date.

            Subject to the provisions of Section 6.1, 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 therefor) to
establish that such notice has been given by a holder of Senior Debt (or a
trustee therefor).  In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a
holder of Senior 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 15.10     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 6.1, 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 Senior Debt and other indebtedness of the Company,





                                       90
<PAGE>   99
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 15.11     Trustee Not Fiduciary for Holders of Senior Debt.

            The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt and shall not be liable to any such holders or creditors
if it shall in good faith 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.

            With respect to the holders of Senior Debt, the Trustee undertakes
to perform or to observe only such of its covenants or obligations as are
specifically set forth in this Article XV and no implied covenants or
obligations with respect to holders of Senior Debt shall be read into this
Indenture against the Trustee.

SECTION 15.12     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 6.5.

SECTION 15.13     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 15.12 shall not apply to the Company
or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.


SECTION 15.14     Certain Conversions Deemed Payment.





                                       91
<PAGE>   100
            For the purposes of this Article only, (1) the issuance and
delivery of junior securities upon conversion of Securities in accordance with
Article XIV shall not be deemed to constitute a payment or distribution on
account of the principal of or premium or interest on Securities or on account
of the purchase or other acquisition of Securities, and (2) the payment,
issuance or delivery of cash, property or securities (other than junior
securities) 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. 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 XIV.

counterparts shall together constitute but one and the same instrument.

Legg Mason, Inc.
111 South Calvert Street
Baltimore, Maryland 21202

Ladies and Gentlemen:

                 We are acting as counsel for Legg Mason, Inc., a Maryland
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended, of a registration statement on Form S-3 (as the same may be amended or
supplemented from time to time, the "Registration Statement"), including the
Prospectus included therein at the time the Registration Statement is declared
effective (the "Prospectus"), with respect to the following securities:  (i)
debt securities of the Company ("Debt Securities"), and (ii) debt securities of
the Company convertible or exchangeable into shares of Common Stock, par value
$.10 per share ("Common Stock"), of the Company ("Convertible Debt
Securities"), to be issued from time to time in one or more series, on terms to
be determined at the time of offering.  The aggregate gross proceeds from the
offer, sale and distribution of the above securities under the Registration
Statement will not exceed $150 million.

                 The Debt Securities and Convertible Debt Securities (the
"Securities") are to be issued from time to time as (i) senior indebtedness
(including senior indebtedness convertible or exchangeable into shares of
Common Stock) of the Company under an indenture between the Company, as issuer,
and The Bank of New York, as trustee, in substantially the form included in the
Registration Statement as Exhibit 4(a), or (ii) subordinated indebtedness
(including subordinated indebtedness convertible or exchangeable into shares of
Common Stock) of the Company under an indenture between the Company, as issuer,
and The Bank of New York, as trustee, in substantially the form included in the
Registration Statement as Exhibit 4(b) (collectively, the "Indentures").

                 In so acting, we have examined the Registration Statement, the
Indentures and the Company's articles of incorporation, as amended.  We have
also examined and relied as to factual matters upon the representations,
warranties and other statements contained in originals, or copies certified or
otherwise
<PAGE>   2
identified to our satisfaction, of such records, documents, certificates and
other instruments as in our judgment are necessary or appropriate to enable us
to render the opinions expressed below.  In such examination, we have assumed
the genuineness of all signatures, the authenticity of all documents,
certificates and instruments submitted to us as originals and the conformity
with originals of all documents submitted to us as copies.

                 Our opinions expressed below are limited to the law of the
State of New York and the federal law of the United States, and we do not
express any opinion herein concerning any other law except to the extent set
forth in the next sentence.  In giving the opinions set forth in paragraphs
(1), (2) and (4) below with regard to certain matters governed by the law of
the State of Maryland, we have relied, with his permission, upon the opinion of
Theodore S.  Kaplan, General Counsel of the Company, of even date herewith,
subject to the qualifications and assumptions set forth in such opinion.

                 Based upon the foregoing, and having regard for such legal
considerations as we have deemed relevant, we are of the opinion that:

                 1.       The Company is a corporation validly existing and in
                          good standing under the laws of the State of
                          Maryland.

                 2.       When executed by a duly authorized officer of the
                          Company, the Indentures and the Securities will have
                          been duly authorized by the Company.

                 3.       When (a) the Indentures have been duly executed and
                          delivered by the parties thereto, (b) the Securities
                          have been duly executed and issued in accordance with
                          the provisions of the applicable Indenture (including
                          the provisions of the Indenture regarding
                          establishment of the form of Securities), (c) such
                          Securities have been authenticated by the trustee
                          under the applicable Indenture and (d) such
                          Securities have been delivered for due consideration
                          in the manner and on the terms described in the
                          Prospectus, as supplemented by the applicable
                          prospectus supplement, such Securities will have been
                          validly issued and will constitute valid and binding
                          obligations of the Company enforceable against the
                          Company in accordance with their respective terms and
                          entitled to the benefits of the applicable Indenture,
                          subject to (i) the effect of any applicable
                          bankruptcy, insolvency (including, without
                          limitation, all laws relating to fraudulent
                          transfers), reorganization, moratorium or similar
                          laws affecting creditors' rights generally and (ii)
                          the effect of general principles of equity

                          (regardless of whether considered in a proceeding in
                          equity or at law).

                 4.       The Common Stock issuable pursuant to the conversion
                          or exchange of Convertible Debt Securities, when duly
                          authorized by the stockholders of the Company and
                          issued upon such conversion or exchange in accordance
                          with the terms of Convertible Debt Securities, will
                          be validly issued, fully paid and nonassessable.

                 We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement and to the reference to us under the heading
"Legal Matters" contained in the Prospectus.

                                        Very truly yours,
