ITEM 17. UNDERTAKINGS
 
      (a) The 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 therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
      (b) The Registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act ("Act") in accordance with the
rules and regulations prescribed by the Securities and Exchange Commission
under Section 305(b)(2) of the Act.
 
      (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
      (d) The undersigned registrant hereby undertakes that:
 
    (1) 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)
 
                                      II-2
<PAGE>
 
  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.
 
    (2) 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.

Ladies and Gentlemen:


     Motorola Capital Trust I (the "Trust"), a statutory business trust
organized under the Business Trust Act (the "Delaware Act") of the State of
Delaware (Chapter 38, Title 12, of the Delaware Code, 12 Del. C. (S)(S) 3801 et

Underwriters named in Schedule A hereto (collectively, the "Underwriters", which
term shall also include any underwriter substituted as hereinafter provided in
Section 10 hereof), for whom Merrill Lynch, A.G. Edwards & Sons, Inc., Goldman,
Sachs & Co., Morgan Stanley & Co. Incorporated, PaineWebber Incorporated,
Prudential Securities Incorporated and Salomon Smith Barney Inc. are acting as
representatives (in such capacity, the "Representatives") with respect to the
issue and sale by the Offerors and the purchase by the Underwriters, acting
severally and not jointly, of the respective number of the Trust's preferred
securities (liquidation preference $25 per preferred security) representing
preferred undivided beneficial interests in the assets of the Trust ("TOPrS" or
the "Trust Preferred Securities") set forth in said Schedule A.

     The payment of periodic cash distributions with respect to the Trust
Preferred Securities and payments on liquidation or redemption with respect to
such Trust Preferred Securities will be each guaranteed by the Company on behalf
of the Trust (the "Preferred Securities Guarantee"), in each case only out of
funds held by the Trust, pursuant to the Preferred Securities Guarantee
Agreement (the "Preferred Securities Guarantee Agreement"), to be entered into
between the Company and a guarantee trustee (the "Guarantee Trustee"), and
entitled to the benefits of certain backup undertakings described in the
Prospectus (as defined below) with respect to the Company's agreement pursuant
to the Indenture (as defined below) to pay all expenses relating to
administration of the Trust (the "Undertakings").  The Trust Preferred
Securities and the related Preferred Securities Guarantee are referred to herein
as the "Offered Securities."

     The Offerors understand that the Underwriters propose to make a public
offering of the Offered Securities as soon as the Representatives deem advisable
after this Agreement has been executed and delivered.

     The entire proceeds from the sale of the Offered Securities will be
combined with the entire proceeds from the sale by the Trust to the Company of
its undivided common beneficial interests in the Trust's assets represented by
common securities (the "Common Securities") and will be used by the Trust to
purchase the unsecured deferrable interest junior subordinated debentures (the
"Subordinated Debentures") of the Company issued by the Company to the Trust.
The Trust Preferred Securities and the Common Securities for the Trust will be
issued pursuant to an amended and restated Declaration of Trust of the Trust
(the "Declaration"), among the Company, as Sponsor, Carl F. Koenemann and Garth
L. Milne, as the regular trustees (the "Regular Trustees"), Harris Trust and
Savings Bank, an Illinois banking corporation, as property trustee (the
"Property Trustee"), and First Union Trust Company, National Association (the
"Delaware Trustee" and, together with the Regular Trustees and the Property
Trustee, the 

                                       2
<PAGE>
 
"Trustees"), and the holders from time to time of undivided beneficial interests
in the assets of the Trust. The Subordinated Debentures will be issued pursuant
to an indenture (as may be supplemented from time to time, the "Indenture"),
between the Company and Harris Trust and Savings Bank, as trustee (the "Debt
Trustee").

     The Offerors have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-70827) for the
registration of up to a combination of $500,000,000 of (i) Trust Preferred
Securities, (ii) Preferred Securities Guarantees, and (iii) Subordinated
Debentures under the Securities Act of 1933, as amended (the "1933 Act"), and
the offering thereof under the 1933 Act.  Such registration statement has been
declared effective by the Commission and the Indenture has been duly qualified
under the Trust Indenture Act of 1939, as amended (the "1939 Act").  Such
registration statement (as so amended, if applicable), including the
information, if any, deemed to be a part thereof pursuant to Rule 430A(b) of the
rules and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations") (the "Rule 430A Information") or Rule 434(d) of the 1933 Act
Regulations (the "Rule 434 Information"), is referred to herein as the
"Registration Statement"; and the final prospectus relating to the offering of
the Offered Securities, in the form first furnished to the Underwriters by the
Company for use in connection with the offering of the Offered Securities, is
referred to herein as the "Prospectus"; provided, however, that all references
to the "Registration Statement" and the "Prospectus" shall also be deemed to
include all documents incorporated therein by reference pursuant to the
Securities Exchange Act of 1934, as amended (the "1934 Act"), prior to the
execution of this Agreement; provided, further, that if the Offerors file a
registration statement with the Commission pursuant to Rule 462(b) of the 1933
Act Regulations (the "Rule 462(b) Registration Statement"), then, after such
filing, all references to the "Registration Statement" shall also be deemed to
include the Rule 462(b) Registration Statement; and provided, further, that if
the Company elects to rely upon Rule 434 of the 1933 Act Regulations, then all
references to the "Prospectus" shall also be deemed to include the final or
preliminary prospectus and the applicable term sheet or abbreviated term sheet
(the "Term Sheet"), as the case may be, in the form first furnished to the
Underwriters by the Company in reliance upon Rule 434 of the 1933 Act
Regulations, and all references in this Agreement to the date of the Prospectus
shall mean the date of the Term Sheet.  A "preliminary prospectus" shall be
deemed to refer to any prospectus used before the Registration Statement became
effective and any prospectus that omitted, as applicable, the Rule 430A
Information, the Rule 434 Information or other information to be included upon
pricing in a form of prospectus filed with the Commission pursuant to Rule
424(b) of the 1933 Act Regulations and was used after such effectiveness and
prior to the execution and delivery of this Agreement.  For purposes of this
Agreement, all references to the Registration Statement, Prospectus, Term Sheet
or preliminary prospectus or to any amendment or supplement to any of the
foregoing shall be deemed to include any copy filed with the Commission pursuant
to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" (or other
references of like import) in the Registration Statement, Prospectus or
preliminary prospectus shall be deemed to mean and include all such financial
statements and schedules and other information which is incorporated by
reference in the 

                                       3

Registration Statement, Prospectus or preliminary prospectus, as the case may
be, prior to the execution of this Agreement; and all references in this
Agreement to amendments or supplements to the Registration Statement, Prospectus
or preliminary prospectus shall be deemed to mean and include the filing of any
document under the 1934 Act which is incorporated by reference in the
Registration Statement, Prospectus or preliminary prospectus, as the case may
be, after the execution of this Agreement.

     SECTION 1.  Representations and Warranties.

     (a) Each Offeror jointly and severally represents and warrants to each
Underwriter as of the date hereof and as of the Closing Time referred to in
Section 2(b) hereof (each such date being hereinafter referred to as a
"Representation Date") and agrees with each Underwriter as follows:

          (i) Each of the Offerors meets the requirements for use of Form S-3
     under the 1933 Act.  The Registration Statement (including any Rule 462(b)
     Registration Statement) has become effective under the 1933 Act and no stop
     order suspending the effectiveness of the Registration Statement (or such
     Rule 462(b) Registration Statement) has been issued under the 1933 Act and
     no proceedings for that purpose have been instituted or are pending or, to
     the knowledge of the Company, are contemplated by the Commission, and any
     request on the part of the Commission for additional information has been
     complied with.

          At the respective times the Registration Statement (including any Rule
     462(b) Registration Statement) and any post-effective amendments thereto
     (including the filing of the Company's most recent Annual Report on Form
     10-K with the Commission (the "Annual Report on Form 10-K")) became
     effective and at each Representation Date, the Registration Statement
     (including any Rule 462(b) Registration Statement) and any amendments
     thereto complied and will comply in all material respects with the
     requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act
     and the rules and regulations of the Commission under the 1939 Act (the
     "1939 Act Regulations") and did not and will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading.  Each preliminary prospectus and prospectus filed as part of
     the Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations.  At the date
     of the Prospectus and at the Closing Time (as defined below), neither the
     Prospectus nor any amendments and supplements thereto included or will
     include an untrue statement of a material fact or omitted or will omit to
     state a material fact necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading;
     provided, however, that the representations and warranties in this
     subsection shall not apply to statements in or omissions from the
     Registration Statement or the Prospectus made in reliance upon and in
     conformity with information furnished to the Company in writing by any
     Underwriter, or on behalf of any Underwriter by the Representatives,
     expressly for use in the Registration 

                                       4
<PAGE>
 
     Statement or the Prospectus. If the Offerors elect to rely upon Rule 434 of
     the 1933 Act Regulations, the Offerors will comply with the requirements of
     Rule 434.

          (ii) The documents incorporated by reference in the Prospectus, at the
     time they were or hereafter are filed with the Commission, complied and
     will comply in all material respects with the requirements of the 1934 Act
     and the rules and regulations of the Commission thereunder (the "1934 Act
     Regulations") and, when read together and with the other information in the
     Prospectus, at the time the Registration Statement and any amendments
     thereof became or become effective under the 1933 Act and at the Closing
     Time did not and will not contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein, in the light of the circumstances under which
     they are made, not misleading.

          (iii) The Company and its subsidiaries considered as a whole have not
     sustained since the date of the latest financial statements included or
     incorporated by reference in the Prospectus any material loss or
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth,
     incorporated by reference or contemplated in the Prospectus; and, since the
     respective dates as of which information is given in the Registration
     Statement and the Prospectus, except as otherwise stated or incorporated
     therein, there has not been any change in the capital stock (other than
     upon exercise of outstanding stock options or upon conversion of
     convertible securities outstanding on the date of the most recent balance
     sheet included in the Prospectus or pursuant to the Company's employee
     stock ownership plan or pursuant to the Company's employee stock purchase
     plans or the Company's employee savings and profit sharing plan), any
     significant increase in the long-term debt of the Company and its
     subsidiaries taken as a whole, or any material adverse change, or any
     development which the Company has reasonable cause to believe will involve
     a prospective material adverse change, in or affecting the general affairs,
     management, consolidated financial position, stockholders' equity or
     results of operations of the Company and its subsidiaries considered as a
     whole, or, other than the Company's regular quarterly dividend, any
     dividend or distribution of any kind declared, paid or made by the Company
     on any class of its capital stock.

          (iv) The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the State of Delaware,
     with corporate power and authority to conduct its business as described in
     the Prospectus with only such exceptions as are not material to the
     business of the Company and its subsidiaries considered as a whole.

          (v) The authorized capitalization is as set forth or incorporated by
     reference in the Prospectus and all of the issued and outstanding shares of
     capital stock of the Company have been duly authorized and validly issued
     and are fully paid and non-assessable.

                                       5

          (vi) The execution, delivery and performance of this Agreement, the
     Declaration, the Indenture, the Preferred Securities, the Common
     Securities, the Subordinated Debentures, the Preferred Securities
     Guarantee, and the Preferred Securities Guarantee Agreement, and the
     consummation of the transactions contemplated herein and therein have been
     duly authorized by all necessary corporate action and will not conflict
     with or constitute a breach of, or a default under, any material contract,
     indenture, mortgage, loan agreement, note, lease or other agreement or
     instrument to which the Company is a party or by which the Company is
     bound; nor will such action result in a violation of the provisions of the
     Company's Restated Certificate of Incorporation or bylaws of the Company,
     as amended, or any applicable law, rule, regulation, judgment, order or
     administrative or court decree; and the Company has corporate power and
     authority to purchase, own and hold the Common Securities.

          (vii) Other than (a) as set forth, incorporated by reference, or
     contemplated in the Prospectus and (b) litigation incident to the kind of
     business conducted by the Company and its subsidiaries, which in the case
     of those items in (b) individually and in the aggregate is not material to
     the Company and its subsidiaries considered as a whole, there are no legal
     or governmental proceedings pending to which the Company and its
     subsidiaries is a party or of which any property of the Company or any of
     its subsidiaries is the subject which, if determined adversely to the
     Company or its subsidiaries, the Company has reasonable cause to believe
     would individually or in the aggregate have a material adverse effect on
     the consolidated financial position, stockholders' equity or results of
     operations of the Company and its subsidiaries considered as a whole; and,
     to the best of the Company's knowledge, no such proceedings are threatened
     or contemplated by governmental authorities or threatened by others.

          (viii) No consent, approval or authorization of any court or
     governmental authority or agency is necessary in connection with the sale
     of the Offered Securities or the consummation of the other transactions
     contemplated by this Agreement, the Declaration, the Indenture or the
     Preferred Securities Guarantee Agreement, except as may be required under
     the 1933 Act or 1933 Act Regulations, the 1934 Act or 1934 Act Regulations,
     the 1939 Act or state securities laws.

          (ix) The Trust has been duly created and is validly existing in good
     standing as a business trust under the Delaware Act with the power and
     authority to own property and to conduct its business as described in the
     Registration Statement and Prospectus and to enter into and perform its
     obligations under this Agreement, the Preferred Securities, the Common
     Securities and the Declaration; the Trust is duly qualified to transact
     business as a foreign company and is in good standing in any other
     jurisdiction in which such qualification is necessary, except to the extent
     that the failure to so qualify or be in good standing would not have a
     material adverse effect on the Trust; the Trust is not a party to or
     otherwise bound by any agreement other than those described in the
     Prospectus; the Trust is and will be classified for United States federal
     income tax purposes as a grantor trust and not as an association 

                                       6
<PAGE>
 
     taxable as a corporation; and the Trust is and will be treated as a
     consolidated subsidiary of the Company pursuant to generally accepted
     accounting principles.

          (x) The Common Securities have been duly authorized by the
     Declaration and, when issued and delivered by the Trust to the Company
     against payment therefor as described in the Registration Statement and
     Prospectus, will be validly issued and (subject to the terms of the
     Declaration) fully paid and non-assessable undivided beneficial interests
     in the assets of the Trust and will conform to all statements relating
     thereto contained in the Prospectus; the issuance of the Common Securities
     is not subject to preemptive or other similar rights; and at the Closing
     Time all of the issued and outstanding Common Securities of the Trust will
     be directly owned by the Company free and clear of any security interest,
     mortgage, pledge, lien, encumbrance, claim or equity.

          (xi) This Agreement has been duly authorized, executed and delivered
     by each of the Offerors.

          (xii) The Declaration has been duly authorized by the Company and, at
     the Closing Time, will have been duly executed and delivered by the Company
     and the Regular Trustees, and assuming due authorization, execution and
     delivery of the Declaration by the Property Trustee and the Delaware
     Trustee, the Declaration will, at the Closing Time, be a valid and binding
     obligation of the Company and the Regular Trustees, enforceable against the
     Company and the Regular Trustees in accordance with its terms, except to
     the extent that enforcement thereof may be limited by bankruptcy,
     insolvency, reorganization, moratorium or other similar laws affecting
     creditors rights generally or by general principles of equity (regardless
     of whether enforcement is considered in a proceeding at law or in equity)
     (the "Bankruptcy Exceptions") and will conform in all material respects to
     all statements relating thereto in the Prospectus.

          (xiii) The Preferred Securities Guarantee Agreement has been duly
     authorized by the Company and, at the Closing Time will have been duly
     executed and delivered by the Company, and, assuming due authorization,
     execution and delivery of the Preferred Securities Guarantee Agreement by
     the Guarantee Trustee, will constitute a valid and binding obligation of
     the Company, enforceable against the Company in accordance with its terms
     except to the extent that enforcement thereof may be limited by the
     Bankruptcy Exceptions, and the Preferred Security Guarantee and the
     Preferred Securities Guarantee Agreement will conform in all material
     respects to all statements relating thereto contained in the Prospectus.

          (xiv) The Trust Preferred Securities have been duly authorized by the
     Declaration and, when issued and delivered pursuant to this Agreement
     against payment of the consideration set forth in Section 2, will be

     non-assessable undivided beneficial interests in the Trust, will be
     entitled to the benefits of the Declaration and will conform to all
     statements relating thereto contained in the Prospectus and such
     description conforms to the provisions of the 

                                       7
<PAGE>
 
     Declaration; the issuance of the Trust Preferred Securities is not subject
     to preemptive or other similar rights; and (subject to the terms of the
     Declaration) holders of Trust Preferred Securities will be entitled to the
     same limitation of personal liability under Delaware law as extended to
     stockholders of private corporations for profit.

          (xv) The Indenture has been duly authorized by the Company and, at the
     Closing Time will have been duly executed and delivered by the Company,
     will constitute a valid and binding agreement of the Company, enforceable
     against the Company in accordance with its terms except to the extent that
     enforcement thereof may be limited by the Bankruptcy Exceptions; and the
     Indenture will conform in all material respects to all statements relating
     thereto contained in the Prospectus.

          (xvi) The Subordinated Debentures have been duly authorized by the
     Company and, at the Closing Time, will have been duly executed by the
     Company and, when authenticated in the manner provided for in the Indenture
     and delivered against payment therefor as described in the Prospectus, will
     constitute valid and binding obligations of the Company, enforceable
     against the Company in accordance with their terms except to the extent
     that enforcement thereof may be limited by the Bankruptcy Exceptions, will
     be in the form contemplated by, and entitled to the benefits of, the
     Indenture and will conform in all material respects to all statements
     relating thereto in the Prospectus.

          (xvii) The Company's obligations under the Preferred Securities
     Guarantee are subordinate and junior in right of payment to all liabilities
     of the Company and are pari passu with the most senior preferred stock
     issued by the Company.

          (xviii) The Subordinated Debentures are subordinated and junior in
     right of payment to all "senior indebtedness" (as defined in the Indenture)
     of the Company.

          (xix) Each of the Regular Trustees is an employee of the Company and
     has been duly authorized by the Company to execute and deliver the
     Declaration; the Declaration has been duly executed and delivered by the
     Regular Trustees and is a valid and binding obligation of each Regular
     Trustee, enforceable against such Regular Trustee in accordance with its
     terms except to the extent that enforcement thereof may be limited by the
     Bankruptcy Exceptions.

          (xx) The Trust is not in violation of its Declaration or its
     certificate of trust as filed with the State of Delaware (the "Certificate
     of Trust"); the Trust is not in default in the performance or observance of
     any material obligation, agreement, covenant or condition contained in any
     contract, indenture, mortgage, loan agreement, note, lease or other
     instrument to which the Trust is a party or by which it may be bound, or to
     which any of the property or assets of the Trust is subject; and the
     execution, delivery and performance of this Agreement, the Declaration, the
     Preferred Securities, the Common Securities, the Indenture, the
     Subordinated Debentures, the Preferred Securities Guarantee Agreement and
     the

     and do not and will not result in any violation of the Declaration or
     Certificate of Trust and do not and will not conflict with, or result in a
     breach of any of the terms or provisions of, or constitute a default under,
     or result in the creation or imposition of any lien, charge or encumbrance
     upon any property or assets of the Trust under (A) any contract, indenture,
     mortgage, loan agreement, note, lease or other agreement or instrument to
     which the Trust is a party or by which it may be bound or to which any of
     its properties or assets may be subject, or (B) any existing applicable
     law, rule, regulation, judgment, order or decree of any government,
     governmental instrumentality or court, domestic or foreign, or any
     regulatory body or administrative agency or other governmental body having
     jurisdiction over the Trust or any of its respective properties or assets.

          (xxi) The Indenture, the Preferred Securities Guarantee Agreement and
     the Declaration have each been duly qualified under the 1939 Act.

          (xxii) None of the Offerors is, and upon the issuance and sale of the
     Offered Securities and the issuance of the Subordinated Debentures and the
     Common Securities as herein contemplated and the application of the net
     proceeds therefrom as described in the Prospectus will not be, an
     "investment company" or a company controlled by an "investment company"
     within the meaning of the Investment Company Act of 1940, as amended (the
     "1940 Act").

          (xxiii) Each Offeror has complied and will comply with the provisions
     of Florida H.B. 1771, codified as Section 517.075 of the Florida Statutes,
     1987, as amended, and all regulations promulgated thereunder relating to
     issuers doing business in Cuba.

     (b) Any certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters in connection with the
offering of the Offered Securities shall be deemed a representation and warranty
by the Company as to the matters covered thereby to each Underwriter.

     SECTION 2.  Sale and Delivery to the Underwriters; Closing.

     (a) On the basis of the representations and warranties herein contained and
subject to the terms and conditions herein set forth, the Offerors agree to sell
to each Underwriter, severally and not jointly, and each Underwriter, severally
and not jointly, agrees to purchase from the Offerors, at the price and on such
terms set forth in Schedule B, the number of Offered Securities set forth in
Schedule A opposite the name of such Underwriter.

     (b)  Payment of the purchase price for, and delivery of, any Offered
Securities to be purchased by the Underwriters shall be made at the offices of
Mayer, Brown & Platt, 190 South LaSalle Street, Chicago, Illinois, or at such
other place as shall be agreed upon by the 

                                       9
<PAGE>
 
Representatives and the Company, on the third business day (unless postponed in
accordance with the provisions of Section 9) after the date hereof, unless the
Offered Securities are priced after 4:30 p.m. New York time in which case such
payment and delivery will be made on the fourth business day following the date
hereof (unless postponed in accordance with the provisions of Section 9), or
such other time not later than ten business days after such date as shall be
agreed upon by the Representatives and the Company (such time and date being
referred to as a "Closing Time"). Payment shall be made to the Trust by wire
transfer of immediately available funds to a bank account designated by the
Company, against delivery to the Representatives for the respective accounts of
the Underwriters of the Offered Securities to be purchased by them. It is
understood that each Underwriter has authorized Merrill Lynch, for its account,
to accept delivery of, receipt for, and make payment of the purchase price for,
the Offered Securities which it has severally agreed to purchase. Merrill Lynch,
individually and not as representative of the Underwriters, may (but shall not
be obligated to) make payment of the purchase price for the Offered Securities
to be purchased by any Underwriter whose funds have not been received by the
Closing Time but such payment shall not relieve such Underwriter from its
obligations hereunder.

     As compensation to the Underwriters for their commitments hereunder and in
view of the fact that the proceeds of the sale of the Trust Preferred Securities
will ultimately be used to purchase the Subordinated Debentures of the Company,
the Company hereby agrees to pay at Closing Time to Merrill Lynch, for the
accounts of the several Underwriters, a commission per Trust Preferred Security
set forth on Schedule B hereto.  At the Closing Time, the Company will pay, or
cause to be paid, the commission payable at such time to the Underwriters under
this Section 2 by wire transfer of immediately available funds to a bank account
designated by Merrill Lynch for the account of the Underwriters.

     (c) Certificates for the Offered Securities shall be in such denominations
and registered in such names as the Representatives may request in writing at
least one business day before the Closing Time.  The certificates for the
Offered Securities, which may be in temporary form, will be made available for
examination and packaging by the Representatives in New York City not later than
10:00 a.m. (Eastern Time) on the last business day prior to the Closing Time.

     SECTION 3.  Covenants.  Each of the Offerors jointly and severally covenant
with the Representatives and with each Underwriter as follows:

     (a) The Offerors, subject to Section 3(b), will comply with the
requirements of Rule 430A of the 1933 Act Regulations and/or Rule 434 of the
1933 Act Regulations, if and as applicable, and will notify the Representatives
immediately, and confirm the notice in writing, of (i) the effectiveness of any
post-effective amendment to the Registration Statement or the filing of any
supplement or amendment to the Prospectus, (ii) the receipt of any comments on
the Registration Statement or the Prospectus from the Commission, (iii) any
request by the Commission for any amendment to the Registration Statement or any
amendment or supplement to the Prospectus or for additional information, and
(iv) the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or of any order preventing or
suspending the use of any 

                                       10
<PAGE>
 
preliminary prospectus, or of the suspension of the qualification of the Offered
Securities for offering or sale in any jurisdiction, or of the initiation or
threatening of any proceedings for any of such purposes. The Offerors will
promptly effect the filings necessary pursuant to Rule 424 and will take such
steps as it deems necessary to ascertain promptly whether the Prospectus
transmitted for filing under Rule 424 was received for filing by the Commission
and, in the event that it was not, it will promptly file the Prospectus. The
Offerors will make every reasonable effort to prevent the issuance of any stop
order and, if any stop order is issued, to obtain the lifting thereof at the
earliest possible moment.

     (b) Each Offeror will give the Representatives notice of its intention to
file or prepare any amendment to the Registration Statement (including any
filing under Rule 462(b) of the 1933 Act Regulations) or any amendment,
supplement or revision to the Prospectus, whether pursuant to the 1933 Act, the
1934 Act or otherwise, will furnish the Representatives with copies of any such
documents a reasonable amount of time prior to such proposed filing or use, as
the case may be, and will not file or use any such document to which the
Representatives or counsel for the Underwriters shall reasonably object.

     (c) The Company, during the period when the Prospectus is required to be
delivered under the 1933 Act, will file promptly all reports and any definitive
proxy or information statements required to be filed by the Company with the
Commission pursuant to Sections 13(a), 13(c), 14 or 15(d) of the 1934 Act.

     (d) The Company will deliver to each of the Representatives two copies of
the Registration Statement as originally filed and of each amendment thereto
(including exhibits filed therewith or incorporated by reference therein and, if
applicable, documents incorporated by reference into the Prospectus pursuant to
Item 12 of Form S-3 under the 1933 Act) and will also deliver to the
Representatives, from time to time during the period when the Prospectus is
required to be delivered under the 1933 Act or the 1934 Act, as many conformed
copies of the Registration Statement as originally filed and of each amendment
thereto (without exhibits) as the Representatives may reasonably request.  The
Registration Statement and each amendment thereto furnished to the Underwriters
will be identical to any electronically transmitted copies thereof filed with
the Commission pursuant to EDGAR, except to the extent permitted by Regulation
S-T.

     (e) The Company has delivered to each Underwriter, without charge, as many
copies of each preliminary prospectus as such Underwriter may reasonably
request, and the Offerors hereby consent to the use of such copies for purposes
permitted by the 1933 Act.  The Company will furnish to each Underwriter,
without charge, prior to 1:00 p.m., New York City time, on the business day next
succeeding the date of this Agreement and from time to time during the period
when the Prospectus is required to be delivered under the 1933 Act or the 1934
Act, such number of copies of the Prospectus as such Underwriter may reasonably
request.  The Prospectus and any amendments or supplements thereto furnished to
the Underwriters will be identical to any electronically transmitted copies
thereof filed with the Commission pursuant to EDGAR, except to the extent
permitted by Regulation S-T.

                                       11
<PAGE>
 
     (f) The Offerors will comply with the 1933 Act and the 1933 Act Regulations
and the 1934 Act and the 1934 Act Regulations so as to permit the completion of
the distribution of the Offered Securities as contemplated in this Agreement and
in the Registration Statement and the Prospectus.  If at any time when the
Prospectus is required by the 1933 Act to be delivered in connection with sales
of the Offered Securities any event shall occur as a result of which it is
necessary to amend or supplement the Prospectus in order to make the Prospectus
not misleading in the light of the circumstances existing at the time it is
delivered to a purchaser, the Company will forthwith amend or supplement the
Prospectus (in form and substance satisfactory to your counsel) so that, as so
amended or supplemented, the Prospectus will not include an untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances existing at the time it is
delivered to a purchaser, not misleading, and the Company will furnish to the
Representatives a reasonable number of copies of such amendment or supplement.

     (g) The Offerors will endeavor, in cooperation with the Underwriters, to
qualify the Offered Securities and the Subordinated Debentures for offering and
sale under the applicable securities laws of such states and other jurisdictions
as the Representatives may designate; provided, however, that the Offerors shall
not be obligated to file any general consent to service of process or to qualify
as a foreign corporation in any jurisdiction in which it is not so qualified.
In each jurisdiction in which the Offered Securities have been so qualified, the
Offerors will file such statements and reports as may be required by the laws of
such jurisdiction to continue such qualification in effect for so long as may be
required to complete the distribution of the Offered Securities.

     (h) The Company will make generally available to its security holders as
soon as practicable, but not later than 90 days after the period covered
thereby, an earnings statement (in form complying with the provisions of Rule
158 under the 1933 Act) covering a twelve-month period beginning, in each case,
not later than the first day of the Company's fiscal quarter next following the
"effective date" (as defined in said Rule 158) of the Registration Statement.

     (i) Each Offeror will use or cause to be used the net proceeds received by
it from the sale of the Offered Securities in the manner specified in the
Prospectus under "Use of Proceeds".

     (j) The Company will use its best efforts to effect the listing of the
Offered Securities, prior to the Closing Time, on the New York Stock Exchange,
and to cause the Offered Securities to be registered under the 1934 Act.

                                       12
<PAGE>
 
     (k) During a period of 30 days from the date of the Prospectus, the
Offerors and the Company's subsidiaries will not, without the prior written
consent of Merrill Lynch, directly or indirectly, pledge, issue, sell, offer or
contract to sell, grant or sell any option or contract for the sale or purchase
of, or otherwise transfer or dispose of, any Offered Securities, any
Subordinated Debentures, any securities substantially similar thereto, or any
securities convertible into or exercisable or exchangeable for Offered
Securities, Subordinated Debentures or any securities substantially similar
thereto, or file any registration statement under the 1933 Act with respect to
any of the foregoing.

     (l) So long as any Offered Securities are outstanding, the Trust will
continue its existence in good standing as a business trust under the Delaware
Act with power and authority to own property and conduct its business as
described in the Prospectus and the Trust will remain duly qualified to transact
business as a foreign corporation in good standing in each jurisdiction in which
such qualification is necessary, except to the extent that the failure to so
qualify would not, singly or in the aggregate, materially adversely affect the
operations of the Trust.

     (m) The Trust will make generally available to its security holders and to
the Representatives as soon as practicable, but not later than 90 days after the
period covered thereby, an earnings statement of the Company (in form complying
with the provisions of Rule 158 of the 1933 Act Regulations) covering a twelve-
month period beginning not later than the first day of the Trust's fiscal
quarter next following the "effective date" (as defined in said Rule 158) of the
Registration Statement.

     SECTION 4.  Payment of Expenses.  The Company will pay all expenses
incident to the performance of the Offerors' obligations under this Agreement,
including (i) the printing and filing of the Registration Statement as
originally filed and of each amendment thereto, (ii) the copying of this
Agreement, any agreement among Underwriters, the Indenture, the Declaration, the

Securities to the Representatives, the Common Securities to the Company and the

the qualification of the Offered Securities and the Subordinated Debentures
under securities laws in accordance with the provisions of Section 3(g),
including filing fees and the fees and disbursements of counsel for the
Underwriters in connection therewith and in connection with the preparation of

copies of the Registration Statement as originally filed and of each amendment
thereto, of the preliminary prospectus, of any Term Sheet and of the Prospectus
and any amendments or supplements thereto, (vii) the printing and delivery to
the Underwriters of copies of the Blue Sky surveys, (viii) the fees and expenses
of the Property Trustee, the Delaware Trustee, the Guarantee Trustee and the
Debt Trustee, including the fees and disbursements of their respective counsel,
(ix) any fees payable in connection with the rating 

                                       13

the listing of the Offered Securities on the New York Stock Exchange, (xi) the
filing fees incident to the review, if any, by the National Association of

Securities, (xii) the cost of qualifying the Trust Preferred Securities with The
Depository Trust Company, and (xiii) all other costs and expenses incident to
the performance of its obligations hereunder which are not otherwise
specifically provided for in this Section. Except as provided in this Section
and in Sections 6 and 7, the Underwriters will pay all of their own costs and
expenses, including fees and disbursements of their counsel, stock transfer
taxes on resale of any of the Offered Securities by them, and any advertising
expenses which they may incur.

     If this Agreement is terminated by the Representatives in accordance with
the provisions of Section 5 (other than Section 5(j)) or Section 9(a)(i) hereof,
the Company shall reimburse the Underwriters for all of their out-of-pocket
expenses, including the reasonable fees and disbursements of counsel for the
Underwriters, reasonably incurred by the Underwriters in making preparations for
the purchase, sale and delivery of the Offered Securities.

     SECTION 5.  Conditions of Underwriters' Obligations.  The obligations of
the Underwriters to purchase and pay for the Offered Securities pursuant to this
Agreement are subject to the accuracy of the representations and warranties of
the Company and the Offerors contained in Section 1 hereof, to the performance
by the Offerors of their covenants and other obligations hereunder, and to the
following further conditions:

     (a) The Registration Statement, including any Rule 462(b) Registration
Statement, has become effective under the 1933 Act and no stop order suspending
the effectiveness of the Registration Statement shall have been issued under the
1933 Act and no proceedings for that purpose shall have been instituted or be
pending or threatened by the Commission, and any request on the part of the
Commission for additional information shall have been complied with to the
reasonable satisfaction of counsel for the Underwriters.  A prospectus
containing the Rule 430A Information shall have been filed with the Commission

to rely upon Rule 434 of the 1933 Act Regulations, a Term Sheet including the
Rule 434 Information shall have been filed with the Commission in accordance
with Rule 424(b)(7).

     (b) At Closing Time, the Representative shall have received:

          (i) The opinion, dated as of Closing Time, of Carol H. Forsyte,
     Senior Counsel, of the Law Department of the Company, or another attorney
     who is employed by the Company 

                                       14
<PAGE>
 
     who is acceptable to the Representatives (the "Company Counsel"), in form
     and substance reasonably satisfactory to counsel for the Underwriters,
     together with signed or reproduced copies of such letter for each of the
     other Underwriters, to the effect that:

               (1) The Company has been duly incorporated and is validly
          existing as a corporation in good standing under the laws of the State
          of Delaware, with corporate power and authority to conduct its
          business as described in the Prospectus.

               (2) The authorized capitalization of the Company is as set forth
          or incorporated by reference in the Prospectus and all of the issued
          and outstanding shares of capital stock of the Company have been duly
          and validly authorized and issued and are fully paid and non-
          assessable.

               (3) This Agreement has been duly authorized, executed and
          delivered by the Company.

               (4) The Declaration has been duly authorized, executed and
          delivered by the Company and duly executed and delivered by the
          Regular Trustees and constitutes a valid and binding obligation of
          each of the Company and the Trust, enforceable against the Company and
          the Trust in accordance with its terms, except to the extent that the
          enforcement thereof may be limited by the Bankruptcy Exceptions.

               (5) The Registration Statement (including any Rule 462(b)
          Registration Statement) has been declared effective under the 1933
          Act.  Any required filing of the Prospectus pursuant to Rule 424(b)
          has been made in the manner and within the time period required by
          Rule 424(b).  To the best of such counsel's knowledge, no stop order
          suspending the effectiveness of the Registration Statement (or such
          Rule 462(b) Registration Statement) has been issued under the 1933 Act
          and no proceedings for that purpose have been initiated or threatened
          by the Commission.

               (6) At the time the Registration Statement (including any Rule
          462(b) Registration Statement) became effective and at the Closing
          Time, the Registration Statement and the Prospectus (other than the
          financial statements and other financial data and supporting schedules
          included therein and in the documents incorporated by reference into
          the Prospectus, as to which no opinion need be rendered) complied as
          to form in all material respects with the applicable requirements of
          the 1933 Act and the 1933 Act Regulations and the 1939 Act and the
          rules and regulations thereunder and, if applicable, the Rule 434
          Prospectus conforms to the 

                                       15
<PAGE>
 
          requirements of Rule 434 of the 1933 Act Regulations in all material
          respects; the documents incorporated by reference into the Prospectus
          (other than the financial statements and other financial data and
          supporting schedules included therein, as to which no opinion need be
          rendered), when they were filed with the Commission, complied as to
          form in all material respects with the applicable requirements of the
          1934 Act and the 1934 Act Regulations; and to the best of such
          counsel's knowledge and information, there are no contracts,
          indentures, mortgages, loan agreements, notes, leases or other
          instruments required to be described or referred to in the Prospectus
          or to be filed as exhibits to the Registration Statement other than
          those described or referred to therein or filed or incorporated by
          reference thereto and the descriptions thereof or references thereto
          are correct.

               (7) The information in the Prospectus under "Risk Factors,"
          "Motorola Capital Trust I," "Description of the Preferred Securities,"
          "Description of the Subordinated Debentures," "Description of the
          Trust Guarantee," "Effect of Obligations under the Subordinated
          Debentures and the Trust Guarantee" and the information contained in
          the Registration Statement pursuant to Item 15, to the extent that
          such information constitutes summaries of statutes, documents or legal
          proceedings, the Company's  Restated Certificate of Incorporation or
          by-laws or the Declaration, has been reviewed by such counsel and is
          correct in all material respects.

               (8) The Common Securities, the Trust Preferred Securities and the
          Declaration, conform to the descriptions thereof contained in the
          Prospectus.

               (9) To the best of such counsel's knowledge, other than as set
          forth, incorporated by reference or contemplated in the Prospectus,
          there are no legal or governmental proceedings pending to which the
          Company or any of its subsidiaries is a party or of which any property
          of the Company or any of its subsidiaries is the subject, other than
          litigation incident to the kind of business conducted by the Company
          and its subsidiaries, which litigation incident to the Company's
          business individually and in the aggregate is not material to the
          Company and its subsidiaries considered as a whole; and, to the best
          of such counsel's knowledge, no such proceedings are threatened or
          contemplated by governmental authorities or threatened by others.

               (10) No consent, approval, authorization, order, registration or
          qualification of any court or governmental authority or agency is
          required for the due authorization, execution or delivery by the
          Company of this Agreement or for the performance by the Company of the
          transactions contemplated by the Prospectus, this 

                                       16
<PAGE>
 
          Agreement, the Indenture, the Declaration, the Preferred Securities,
          the Common Securities, the Subordinated Debentures, the Preferred
          Securities Guarantee Agreement, and the Preferred Securities
          Guarantee, other than under the 1933 Act, the 1933 Act Regulations,
          the 1934 Act, the 1934 Act Regulations, the 1939 Act and the 1939 Act
          Regulations, which have already been made, obtained or rendered, as
          applicable, or state securities laws.

               (11) The execution and delivery of this Agreement, the
          Declaration, the Preferred Securities, the Common Securities, the
          Indenture, the Subordinated Debentures and the Preferred Securities
          Guarantee Agreement, the issuance and sale of the Preferred Securities
          Guarantee and the Subordinated Debentures, the compliance by the
          Company with all of the provisions of this Agreement, the Declaration,
          the Subordinated Debentures, the Indenture and the Preferred
          Securities Guarantee Agreement and the consummation of the
          transactions contemplated herein, therein and in the Prospectus do not
          and will not conflict with or constitute a breach of, or default
          under, (1) the Restated Certificate of Incorporation or by-laws of the
          Company; (2) any contract, indenture, mortgage, loan agreement, note,
          lease or other agreement or instrument known to such counsel to which
          the Company is a party or by which the Company is bound; or (3) any
          applicable law, rule, regulation, judgment, order or administrative or
          court decree known to such counsel.

               (12) To the best of such counsel's knowledge and information, all
          of the issued and outstanding Common Securities are directly owned by
          the Company free and clear of any lien, encumbrance, equity or claim.

     Such opinion of Company Counsel shall additionally state that nothing has
come to his or her attention that has caused him or her to believe that the
Registration Statement (including any Rule 462(b) Registration Statement) or any
post-effective amendment thereto (other than the financial statements, financial
data and schedules included therein, as to which no belief need be expressed),
at the time the Registration Statement (including any Rule 462(b) Registration
Statement) or any post-effective amendment thereto (including the filing of the
Company's Annual Report on Form 10-K with the Commission) became effective or at
the Closing Time contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus or any amendment or
supplement thereto (other than the financial statements, financial data and
schedules included therein, as to which no belief need be expressed), at the
time the Prospectus was issued, at the time any such amended or supplemented
prospectus was issued or at the Closing Time, included or includes an untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.  Such opinion shall be
limited to the laws of the State of Illinois, the General Corporation Law of the
State of Delaware and the federal law of the United States, and the rules and
regulations thereunder.

                                       17

          (ii) The opinion, dated as of the Closing Time, of Kirkland & Ellis,

     counsel for the Underwriters, together with signed or reproduced copies of
     such letter for each of the other Underwriters to the effect that:

               (1) The Indenture has been duly authorized, executed and
          delivered by the Company and, assuming due authorization, execution,
          and delivery thereof by the Debt Trustee, is a valid and binding
          obligation of the Company, enforceable against the Company in
          accordance with its terms, except to the extent that enforcement
          thereof may be limited by the Bankruptcy Exceptions.

          constitute valid and binding obligations of the Company, enforceable
          against the Company in accordance with their terms and entitled to the
          benefits provided by the Indenture, except to the extent that
          enforcement thereof may be limited by the Bankruptcy Exceptions.

               (3) The Preferred Securities Guarantee Agreement has been duly
          authorized, executed and delivered by the Company and, assuming it is
          duly authorized, executed, and delivered by the Guarantee Trustee, is

          and sale of the Preferred Securities and the issuance of the
          Subordinated Debentures and the Common Securities as herein
          contemplated and the application of the net proceeds therefrom as
          described in the Prospectus will be, an "investment company" or a

               (6) Each of the Offerors meets the registrant requirements for
          use of Form S-3 under the 1933 Act Regulations.

               (7) The Subordinate Debentures, the Preferred Securities
          Guarantee, the Indenture and the Preferred Securities Guarantee
          Agreement conform to the descriptions thereof contained in the
          Prospectus.

     Such opinion of Kirkland & Ellis shall additionally state that nothing has
come to their attention that has caused them to believe that the Registration
Statement (including any Rule 462(b) Registration Statement) or any post-
effective amendment thereto (other than the financial statements, financial data
and schedules included therein, as to which no belief need be expressed), at the
time the Registration Statement (including any Rule 462(b) Registration
Statement) or any post-effective amendment thereto (including the filing of the
Company's Annual Report on Form 10-K with the Commission) became effective or at
the Closing Time contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus or any amendment or
supplement thereto (other than the financial statements, financial data and
schedules included therein, as to which no belief need be expressed), at the
time the Prospectus was issued, at the time any such amended or supplemented
prospectus was issued or at the Closing Time, included or includes an untrue
statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     Such opinion shall also include such Federal tax, ERISA and other related
matters of the type ordinarily included in similar transactions or reasonably
requested by counsel for the Underwriters and shall be limited to the laws of
the State of Illinois, the State of New York, the General Corporation Law of the
State of Delaware and the federal law of the United States, and the rules and
regulations thereunder.

          (iii) The opinion, dated as of the Closing Time, of Richard, Layton &
     Fingers, P.A., special Delaware counsel to the Offerors, in form and
     substance reasonably satisfactory to counsel for the Underwriters, to the
     effect that:

               (1) The Trust has been duly created and is validly existing in
          good standing as a business trust under the Delaware Act and all
          filings required under the 

                                       19
<PAGE>
 
          laws of the State of Delaware with respect to the creation and valid
          existence of the Trust as a business trust have been made. Under the
          Delaware Act and the Declaration, the Trust has the trust power and
          authority to own property and to conduct its business, all as
          described in the Prospectus, to execute and deliver and perform its
          obligations under this Agreement, the Trust Preferred Securities and
          the Common Securities and to purchase and hold the Subordinated
          Debentures.

               (2) The Common Securities have been duly authorized by the
          Declaration and are duly and validly issued undivided beneficial
          interests in the assets of the Trust and, under the Delaware Act and
          the Declaration, the issuance of the Common Securities is not subject
          to preemptive or other similar rights.

               (3) Under the Delaware Act, the certificate attached to the
          Declaration as Exhibit A-1 is an appropriate form of certificate to
          evidence ownership of the Trust Preferred Securities.  The Trust
          Preferred Securities have been duly authorized by the Declaration and
          are duly and validly issued, and, subject to the qualifications set
          forth herein, fully paid and non-assessable undivided beneficial
          interests in the assets of the Trust.  The holders of the Trust
          Preferred Securities will be entitled to the same limitation of
          personal liability extended to stockholders of private corporations
          for profit organized under the General Corporation Law of the State of
          Delaware; and, under the Delaware Act and the Declaration, the
          issuance of the Trust Preferred Securities is not subject to
          preemptive or other similar rights.  Such counsel may note that the
          Trust Preferred Securities holders may be obligated, pursuant to the
          Declaration, to (a) provide indemnity and/or security in connection
          with and pay taxes or governmental charges arising from transfers of
          Trust Preferred Securities and the issuance of replacement Trust
          Preferred Securities, and (b) provide security and indemnity in
          connection with requests of or directions to the Property Trustee to
          exercise its rights and powers under the Declaration.

               (4) Under the Declaration and the Delaware Act, this Agreement
          has been duly authorized by all necessary trust action on the part of
          the Trust.

               (5) No filing with, or authorization, approval, consent, license,
          order, registration, qualification or decree of, any Delaware court or
          Delaware governmental authority or agency is necessary or required
          solely for the due authorization, execution or delivery by the Trust
          of this Agreement or for the performance by the Trust of the
          transactions contemplated under the Prospectus, this Agreement, the
          Declaration, the Preferred Securities and the Common Securities.

               (6) The issuance and sale by the Trust of the Trust Preferred
          Securities and the Common Securities, the purchase by the Trust of the
          Subordinated Debentures, the execution, delivery and performance by
          the Trust of this Agreement, the consummation by the Trust of the
          transactions contemplated hereby and thereby 

                                       20

          and compliance by the Trust with its obligations hereunder and
          thereunder do not violate (A) any of the provisions of the Certificate
          of Trust or the Declaration or (B) any applicable Delaware law or
          administrative regulation.

               (7) The Declaration constitutes a valid and binding obligation of
          the Company and the Trustees, and is enforceable against the Company
          and the Trustees, in accordance with its terms.

          (iv) The favorable opinion, dated as of Closing Time, of Nicholas
     Bullat of the law department of the Property Trustee, the Debt Trustee and
     the Guarantee Trustee, in form and substance satisfactory to counsel for
     the Underwriters to the effect that:

               (1) Harris Trust and Savings Bank is a banking corporation with
          trust powers, duly organized, validly existing and in good standing
          under the laws of Illinois with all necessary power and authority to

          under the terms of the Declaration, the Preferred Securities Guarantee
          Agreement and the Indenture.

               (2) The execution, delivery and performance by the Property
          Trustee of the Declaration, the execution, delivery and performance by
          the Guarantee Trustee of the Preferred Securities Guarantee Agreement
          and the execution, delivery and performance by the Debt Trustee of the
          Indenture have been duly authorized by all necessary corporate action
          on the part of the Property Trustee, the Guarantee Trustee and the
          Debt Trustee, respectively. Assuming the corporate power and legal
          authority of and due authorization, execution and delivery by the
          other parties thereto, the Declaration, the Preferred Securities
          Guarantee Agreement and the Indenture have been duly executed and
          delivered by the Property Trustee, the Guarantee Trustee and the Debt
          Trustee, respectively, and constitute the legal, valid and binding
          obligations of the Property Trustee, the Guarantee Trustee and the
          Debt Trustee, respectively, enforceable against the Property Trustee,
          the Guarantee Trustee and the Debt Trustee, respectively, in
          accordance with their terms, except as enforcement thereof may be
          limited by the Bankruptcy Exceptions.

               (3) The execution, delivery and performance of the Declaration,
          the Preferred Securities Guarantee Agreement and the Indenture by the
          Property Trustee, the Guarantee Trustee and the Debt Trustee,
          respectively, do not conflict with or constitute a breach of the
          Articles of Incorporation or Bylaws of the Property Trustee, the
          Guarantee Trustee and the Debt Trustee, respectively.

               (4) No consent, approval or authorization of, or registration
          with or notice to, any federal banking authority is required for the
          execution, delivery or performance by the Property Trustee, the
          Guarantee Trustee and the Debt Trustee of 

                                       21
<PAGE>
 
          the Declaration, the Preferred Securities Guarantee Agreement and
          Indenture, respectively.

               (5) The Statement of Eligibility on Form T-1 with respect to
          each of the Property Trustee, the Debt Trustee and the Guarantee
          Trustee filed with the Commission as part of the Registration
          Statement complied as to form in all material respects with the
          requirements of the 1939 Act and the 1939 Act Regulations.

          (v) The opinion, dated as of Closing Time, of Marsh, James, Hitchens
     & Williams, counsel for the Delaware Trustee, together with signed or
     reproduced copies of such letter for each of the other underwriters to the
     effect that:

               (1) First Union Trust Company, National Association is a national
          banking association with trust powers, duly organized, validly
          existing and in good standing under the laws of the United States with

               (2) The execution, delivery and performance by the Delaware
          Trustee of the Declaration have been duly authorized by all necessary
          corporate action on the part of the Delaware Trustee.  The Declaration

          Bankruptcy Exceptions.

               (3) The execution, delivery and performance of the Declaration by

          with or notice to, any federal banking authority is required for the

          (vi) The opinion, dated as of Closing Time, of Mayer, Brown & Platt,
     counsel for the Underwriters, together with signed or reproduced copies of
     such letter for each of the other Underwriters, with respect to the matters
     set forth in (A) subsection (b)(i)(1) (insofar as it relates to the
     existence and good standing of the Company), (3), (4) (insofar as it
     relates to the due authorization, execution and delivery of the
     Declaration), (6) (insofar as it relates as to compliance of the
     Registration Statement and the Prospectus as to form), (7) (solely as to
     the information in the Prospectus under "Description of the Preferred
     Securities," "Description of Subordinated Debentures," and "Description of
     the Trust Guarantee"), (8) and the last paragraph of subsection (b)(i) and 
     (B) subsection (b)(ii)(l), (2) and (3) of this Section. In giving such
     opinion, such counsel may rely, as to all matters governed by the laws of
     jurisdictions other than the law of the State of New York, the State of
     Illinois, the federal law of the United States and the General Corporation
     Law of the State of Delaware, upon the opinions of counsel satisfactory to
     the Representatives. Such counsel may also state that, insofar as such
     opinion involves factual matters, they have relied, to the extent they deem
     proper, upon certificates of officers of the Company and its subsidiaries
     and certificates of public officials.

     (c) (i)  The Company and its subsidiaries considered as a whole shall have
not sustained since the date of the latest financial statements included or
incorporated by reference in the Prospectus any loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered

or decree, otherwise than as set forth, incorporated by reference or
contemplated in the Prospectus, and (ii) since the respective dates as of which
information is given in the Registration Statement and the Prospectus there
shall not have been any change in the capital stock (other than upon exercise of
outstanding stock options or upon conversion of convertible securities
outstanding at the date of the most recent balance sheet included in the
Prospectus or pursuant to the Company's employee stock ownership plan or
pursuant to the Company's employee stock purchase plans or the Company's
employee savings and profit sharing plan) or any significant increase in long-
term debt of the Company and its subsidiaries considered as a whole or any
change, or any development involving a prospective change, in or affecting the
general affairs, management, consolidated financial position, stockholders'
equity or results of operations of the Company and its subsidiaries considered
as a whole, otherwise than as set forth or  incorporated by reference or
contemplated in the Prospectus, the effect of which, in any such case described
in clause (i) or 

                                       23
<PAGE>
 
(ii), is in your judgment so material and adverse as to make it impracticable or
inadvisable to proceed with the public offering or the delivery of the Offered
Securities on the terms and in the manner contemplated in the Prospectus.

     (d) On or after the date of this Agreement (i) no downgrading shall have
occurred in the rating accorded the Company's debt securities by any "nationally
recognized statistical rating organization," as that term is defined by the
Commission for purposes of Rule 436(g)(2) under the 1933 Act and (ii) no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities. At the Closing time, the Preferred Securities shall be rated
"A+" by Standard & Poor's Ratings Services and "aa3" by Moody's Investors
Service, Inc.

     (e) You shall have received a certificate of the Vice Chairman and Chief
Executive Officer, the President or another senior officer acceptable to you of
the Company and of the Chief Financial Officer, Controller, Treasurer or
Assistant Treasurer of the Company, dated as of the Closing Time, to the effect
that (i) the Company and its subsidiaries shall not have sustained any loss or
interference with its business of the type specified in Section 5(c)(i) and
there shall not have occurred any change of the type specified in Section
5(c)(ii), (ii) there shall not have occurred any downgrading of the type
specified in Section 5(d), (iii) the applicable representations and warranties
in Section 1 are true and correct with the same force and effect as though
expressly made at and as of such Closing Time, (iv) the Company has complied
with all agreements and satisfied all conditions on its part to be performed or
satisfied at or prior to such Closing Time, and (v) no stop order suspending the
effectiveness of the Registration Statement has been issued and no proceedings
for that purpose have been initiated or threatened by the Commission.

     (f) At the time of the execution of this Agreement, you shall have received
from KPMG LLP a letter dated such date, in form and substance
satisfactory to you, to the effect that (i) they are independent public
accountants with respect to the Company and its subsidiaries within the meaning
of the 1933 Act and the 1933 Act Regulations; (ii) it is their opinion that the
financial statements and supporting schedules included in or incorporated by
reference into the Registration Statement or the Prospectus and covered by their
opinions therein comply as to form in all material respects with the applicable
accounting requirements of the 1933 Act and the 1933 Act Regulations and the
1934 Act and the 1934 Act Regulations; (iii) based upon limited procedures set
forth in detail in such letter, nothing has come to their attention which 

                                       24
<PAGE>
 
causes them to believe that (A) the unaudited financial statements and
supporting schedules of the Company and its subsidiaries included in or
incorporated by reference into the Registration Statement or the Prospectus do
not comply as to form in all material respects with the applicable accounting
requirements of the 1933 Act and the 1933 Act Regulations or the 1934 Act and
the 1934 Act Regulations, as the case may be, or are not presented in conformity
with generally accepted accounting principles applied on a basis substantially
consistent with that of the audited financial statements included in or
incorporated by reference into the Registration Statement or the Prospectus or
(B) at a specified date not more than three days prior to the date of this
Agreement, there has been any change in the capital stock of the Company (other
than upon exercise of outstanding stock options or upon conversion of
convertible securities outstanding on the date of the most recent balance sheet
included in or incorporated by reference into the Prospectus or pursuant to the
Company's employee stock ownership plan or pursuant to the Company's stock
purchase plans or the Company's employee savings and profit sharing plan) or any
increase in the consolidated long term debt of the Company and its subsidiaries
or any decrease in consolidated net current assets or net assets as compared
with the amounts shown in the most recent balance sheet included in or
incorporated by reference into the Prospectus or, during the period from the
date of the most recent financial statements included in or incorporated by
reference into the Prospectus to a specified date not more than three days prior
to the date of this Agreement, there were any decreases, as compared with the
corresponding period in the preceding year, in consolidated net sales, net
earnings or net earnings per share of the Company and its subsidiaries, except
in all instances for changes, increases or decreases which the Registration
Statement and the Prospectus disclose have occurred or may occur; and (iv) in
addition to the examination referred to in their opinions and the limited
procedures referred to in clause (iii) above, they have carried out certain
specified procedures, not constituting an audit, with respect to certain
amounts, percentages and financial information which are included in or
incorporated by reference into the Registration Statement and Prospectus and
which are specified by you, and have found such amounts, percentages and
financial information to be in agreement with the relevant accounting, financial
and other records of the Company and its subsidiaries identified in such letter.

     (g) At Closing Time, the Representatives shall have received from KPMG LLP
a letter, dated as of Closing Time, to the effect that they reaffirm the
statements made in the letter furnished pursuant to subsection (f) of this
Section, except that the specified date referred to shall be a date not more
than three business days prior to Closing Time.

     (h) At Closing Time counsel for the Underwriters shall have been furnished
with such documents and opinions as they may  require for the purpose of
enabling them to pass upon the issuance and sale of the Offered Securities, as
contemplated herein, and related proceedings, or in order to evidence the
accuracy of any of the representations or warranties, or the fulfillment of any
of the conditions, herein contained; and all proceedings taken by the Offerors
in connection with the issuance and sale of the Offered Securities and the
issuance of the Subordinated Debentures shall be reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters.

     (i) At Closing Time, the Offered Securities shall have been approved for
listing, subject only to official notice of issuance, on the New York Stock
Exchange.

     (j) If the Registration Statement or an offering of Offered Securities is

have raised any objection that remains unresolved at Closing Time with respect
to the fairness and reasonableness of the underwriting terms and arrangements.

     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Representatives by notice to the Company at any time at or prior to Closing Time
and such termination shall be without liability of any party to any other party
except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall
survive any such termination and remain in full force and effect.

     SECTION 6.  Indemnification.

     (a) The Offerors agree jointly and severally to indemnify and hold harmless

with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto),
including the Rule 430A Information and the Rule 434 Information deemed to be a
part thereof, if applicable, or any preliminary prospectus or the Prospectus (or

     (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
which it may have otherwise than on account of this indemnity agreement. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein, and to the extent that it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified party (who shall not, except with
the consent of the indemnified party, be counsel to the indemnifying party),
and, after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.  In no event shall the indemnifying parties be liable
for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.

     SECTION 7.  Contribution.  In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
Section 6 is for any reason held to be unenforceable by the indemnified parties
although applicable in accordance with its terms, the Offerors and you shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by said indemnity agreement incurred by the Company and
you, as incurred, in such proportions that you are responsible for that portion
represented by the percentage that the underwriting discount appearing on the
cover page of the Prospectus bears to the initial public offering price
appearing thereon and the Offerors are responsible for the balance; provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  For
purposes of this Section, each person, if any, who controls you within the
meaning of Section 15 of the 1933 Act shall have the same right to contribution
as you, and each director of the Company, the Trustees, each officer of the
Offerors who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act shall have
the same rights to contribution as the Offerors.

     SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements contained in this Agreement, or
contained in certificates of officers of the Company or any of its subsidiaries
submitted pursuant hereto or thereto, shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf 

                                       28
<PAGE>
 
of any Underwriter or controlling person, or by or on behalf of the Offerors,
and shall survive delivery of and payment for the Offered Securities.

     SECTION 9.  Termination of Agreement.

     (a) Merrill Lynch may terminate this Agreement, by notice to the Company,
at any time at or prior to the Closing Time, if (i) the Company and its
subsidiaries considered as a whole shall have sustained since the date of the
latest financial statements included or incorporated by reference in the
Prospectus any loss or interference with its business from fire, explosion,
flood or other calamity, whether or not covered by insurance, or from any labor
dispute or court or governmental action, order or decree, otherwise than as set
forth, incorporated by reference or contemplated in the Prospectus, or since the
respective dates as of which information is given in the Registration Statement
and the Prospectus there shall have been any change in the capital stock (other
than upon exercise of outstanding stock options or upon conversion of
convertible securities outstanding at the date of the most recent balance sheet
included in the Prospectus or pursuant to the Company's employee stock ownership
plan or pursuant to the Company's employee stock purchase plans or the Company's
employee savings and profit sharing plan) or any significant increase in long-
term debt of the Company and its subsidiaries considered as a whole or any
change, or any development involving a prospective change, in or affecting the
general affairs, management, consolidated financial position, stockholders'
equity or results of operations of the Company and its subsidiaries considered
as a whole, otherwise than as set forth or incorporated by reference or
contemplated in the Prospectus, the effect of which, in any such case described
in this clause (i), is in your judgment so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Offered Securities on the terms and in the manner contemplated in the
Prospectus, or (ii) there has occurred any material adverse change in the
financial markets in the United States or any outbreak or escalation of
hostilities involving the United States or the declaration by the United States
of a national emergency or war, or other calamity or crisis or any change or
development involving a prospective change in national or international
political, financial or economic conditions, in each case the effect of which is
such as to make it, in the reasonable judgment of Merrill Lynch, impracticable
or inadvisable to market the Offered Securities or to enforce contracts for the
sale of the Offered Securities, or (iii) a suspension or material limitation in
trading in the Company's Common Stock, the Trust Preferred Securities or
securities generally on the New York Stock Exchange, or (iv) a general
moratorium on commercial banking activities in New York or Illinois has been
declared by either Federal or state authorities.

     (b) If this Agreement is terminated pursuant to this Section 9, such
termination shall be without liability of any party to any other party except as
provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8
shall survive such termination and remain in full force and effect.

     SECTION 10.  Default by One or More of the Underwriters.  If one or more of
the Underwriters shall fail at the Closing Time to purchase the Offered
Securities which it or they are obligated to purchase under this Agreement (the
"Defaulted Securities"), then the Representatives shall have the right, within
24 hours thereafter, to make arrangements for one or more of the 

                                       29
<PAGE>
 
non-defaulting Underwriters, or any other underwriters reasonably acceptable to
the Representatives, to purchase all, but not less than all, of the Defaulted
Securities in such amounts as may be agreed upon and upon the terms herein set
forth; if, however, the Representatives shall not have completed such
arrangements within such 24-hour period, then:

     (a) if the aggregate principal amount of Defaulted Securities does not
exceed 10% of the aggregate principal amount of Offered Securities to be
purchased on such date, the non-defaulting Underwriters shall be obligated,
severally and not jointly, to purchase the full amount thereof in the
proportions that their respective underwriting obligations hereunder bear to the
underwriting obligations of all non-defaulting Underwriters, or

     (b) if the aggregate principal amount of Defaulted Securities exceeds 10%
of the aggregate principal amount of Offered Securities to be purchased on such
date pursuant to this Agreement, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter or the Company.

     No action taken pursuant to this Section 10 shall relieve any defaulting
Underwriter from liability in respect of its default.

     In the event of any such default which does not result in a termination of
this Agreement, either the Representatives or the Company shall have the right
to postpone the Closing Time for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or the Prospectus or
in any other documents or arrangements.

     SECTION 11.  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be directed to Merrill Lynch at Merrill Lynch & Co., 5500
Sears Tower, Chicago, Illinois  60606, Attention: Robert Schmeideler; notices to
the Company or the Trust shall be directed to it at: 1303 East Algonquin Road,
Schaumburg, Illinois 60106, Attention: Treasurer.

     SECTION 12.  Parties.  This Agreement shall each inure to the benefit of
and be binding upon the Underwriters, the Offerors, and their respective
successors.  Nothing expressed or mentioned in this Agreement is intended or
shall be construed to give any person, firm or corporation, other than the
Underwriters and the Offerors and their respective successors and the
controlling persons and officers and directors referred to in Sections 6 and 7
and their heirs and legal representatives, any legal or equitable right, remedy
or claim under or in respect of this Agreement or any provision herein
contained.  This Agreement and all conditions and provisions hereof and thereof
are intended to be for the sole and exclusive benefit of the parties hereto and
thereto and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation.  No purchaser of Offered
Securities from any Underwriter shall be deemed to be a successor by reason
merely of such purchase.

     (a) The Holders of a Majority in Liquidation Amount of the Preferred
Securities may, by vote, on behalf of the Holders of all of the Preferred
Securities, waive any past Event of Default in respect of the Preferred
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

          (i) is not waivable under the Indenture, the Event of Default under
          the Declaration shall also not be waivable; or

          (ii) requires the consent or vote of greater than a majority in
          principal amount of the holders of the Debentures (a "Super Majority")
          to be waived under the Indenture, the Event of Default under the
          Declaration may only be waived by the vote of the Holders of at least
          the proportion in liquidation amount of the Preferred Securities that
          the relevant Super Majority represents of the aggregate principal
          amount of the Debentures outstanding.

The foregoing provisions of this Section 2.6(a) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Declaration and the
Securities, as permitted by the Trust Indenture Act.  Upon such waiver, any such
default shall cease to exist, and any Event of Default with respect to the
Preferred Securities 

                                       9
<PAGE>
 
arising therefrom shall be deemed to have been cured, for every purpose of this
Declaration and the Preferred Securities, but no such waiver shall extend to any
subsequent or other default or Event of Default with respect to the Preferred
Securities or impair any right consequent thereon. Any waiver by the Holders of
the Preferred Securities of an Event of Default with respect to the Preferred
Securities shall also be deemed to constitute a waiver by the Holders of the
Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Declaration without any further act, vote or
consent of the Holders of the Common Securities.

     (b) The Holders of a Majority in Liquidation Amount of the Common
Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default in respect of the Common Securities
and its consequences, provided that, if the underlying Event of Default under
the Indenture:

          (i) is not waivable under the Indenture, except where the Holders of
          the Common Securities are deemed to have waived such Event of Default
          under the Declaration as provided below in this Section 2.6(b), the
          Event of Default under the Declaration shall also not be waivable; or

          (ii) requires the consent or vote of a Super Majority to be waived
          under the Indenture, except where the Holders of the Common Securities
          are deemed to have waived such Event of Default under the Declaration
          as provided below in this Section 2.6(b), the Event of Default under
          the Declaration may only be waived by the vote of the Holders of at
          least the proportion in liquidation amount of the Common Securities
          that the relevant Super Majority represents of the aggregate principal
          amount of the Debentures outstanding;

provided further, that each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and the consequences thereof until all Events of Default with
respect to the Preferred Securities have been cured, waived or otherwise
eliminated, and until such Events of Default with respect to the Preferred
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee will be deemed to be acting solely on behalf of the Holders of the
Preferred Securities and only the Holders of the Preferred Securities will have
the right to direct the Property Trustee in accordance with the terms of the
Securities.  The foregoing provisions of this Section 2.6(b) shall be in lieu of
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
Sections 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Declaration and the Securities, as permitted by the
Trust Indenture Act.  Subject to the foregoing provisions of this Section
2.6(b), upon such waiver, any such default shall cease to exist and any Event of
Default with respect to the Common Securities arising therefrom shall be deemed
to have been cured for every purpose of this Declaration, but no such waiver
shall extend to any subsequent or other default or Event of Default with respect
to the Common Securities or impair any right consequent thereon.

                                      10

     (c) A waiver of an Event of Default under the Indenture by the Property
Trustee at the direction of the Holders of the Preferred Securities constitutes
a waiver of the corresponding Event of Default with respect to the Preferred
Securities under this Declaration. The foregoing provisions of this Section
2.6(c) shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act and
such Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly
excluded from this Declaration and the Securities, as permitted by the Trust
Indenture Act.

     SECTION 2.7   Event of Default; Notice.
                   ------------------------ 

     (a) The Property Trustee shall, within 90 days after the occurrence of an
Event of Default, transmit by mail, first class postage prepaid, to the  Holders
of the Securities, notices of all defaults with respect to the Securities
actually known to a Responsible Officer of the Property Trustee, unless such
defaults have been cured before the giving of such notice (the term "defaults"
for the purposes of this Section 2.7(a) being hereby defined to be an Event of
Default as defined in the Indenture, not including any periods of grace provided
for there in and irrespective of the giving of any notice provided therein);
provided that, except for a default in the payment of principal of (or premium,
if any) or interest on any of the Debentures or in the payment of any sinking
fund installment established for the Debentures, the Property Trustee shall be
protected in withholding such notice if and so long as a Responsible Officer of
the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders of the Securities.

     (b) The Property Trustee shall not be deemed to have knowledge of any
default except:

          (i) a default under Sections 5.1(1) and 5.1(2) of the Indenture; or

          (ii) any default as to which the Property Trustee shall have received
          written notice or of which a Responsible Officer of the Property
          Trustee charged with the administration of this Declaration shall have
          actual knowledge.  As used herein, the term "actual knowledge" means
          the actual fact or statement of knowing without any duty to make any
          investigation without regard thereto.

taken by the Property Trustee on behalf of the Trust in accordance with its
powers shall constitute the act of and serve to bind the Trust.  In dealing with
the Trustees acting on behalf of the Trust, no person shall be required to
inquire into the authority of the Trustees to bind the Trust.  Persons dealing
with the Trust are entitled to rely conclusively on the power and authority of
the Trustees as set forth in this Declaration.

       SECTION 3.5   Title to Property of the Trust.  Except as provided in
Section 3.8 with respect to the Debentures and the Property Trustee Account or

assets of the Trust.

Trustees shall have the exclusive power, duty and authority to cause the Trust

     (a) The legal title to the Debentures shall be owned by and held of record
in the name of the Property Trustee in trust for the benefit of the Trust and 
the Holders of the Securities. The right, title and interest of the Property
Trustee to the Debentures shall vest automatically in each Person who may
hereafter be appointed as Property Trustee in accordance with Section 5.7. Such
vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

     (b) The Property Trustee shall not transfer its right, title and interest
in the Debentures to the Regular Trustees or to the Delaware Trustee (if the
Property Trustee does not also act as Delaware Trustee).

     (c)  The Property Trustee shall:

          (i) establish and maintain a segregated non-interest bearing trust
          account (the "Property Trustee Account") in the name of and under the
          exclusive control of the Property Trustee on behalf of the Holders of
          the Securities and, upon the receipt of payments of funds made in
          respect of the Debentures held by the Property Trustee, deposit such
          funds into the Property Trustee Account and make payments to the
          Holders of the Preferred Securities and the Holders of the Common
          Securities from the Property Trustee Account in accordance with
          Section 6.1.  Funds in the Property Trustee Account shall be held
          uninvested until disbursed in accordance with this Declaration.  The
          Property Trustee Account shall be an account that is maintained with a
          banking institution the rating on whose long-term unsecured
          indebtedness is at least equal to the rating assigned to the Preferred
          Securities by a "nationally recognized statistical rating
          organization," as that term is defined for purposes of Rule 436(g)(2)
          under the Securities Act;

          (ii) engage in such ministerial activities as shall be necessary or
          appropriate to effect the redemption of the Preferred Securities and
          the Common Securities to the extent the Debentures are redeemed or
          mature; and

          (iii)  upon written notice of distribution issued by the Regular
          Trustees in accordance with the terms of the Securities, engage in
          such ministerial activities as shall be necessary or appropriate to
          effect the distribution of the Debentures to Holders of Securities
          upon the liquidation and dissolution of the Trust.

     (d) The Property Trustee shall take all actions and perform such duties as
may be specifically required of the Property Trustee pursuant to the terms of
this Declaration and the Securities.

     (e) To the extent consistent with and not in contravention of the terms and
provisions of this Declaration and the Indenture, with respect to any
compromise, arbitration or adjustment of claims or demands, the Property Trustee
shall take any Legal Action which arises out of or in connection with an Event
of Default of which a Responsible Officer of the Property Trustee has actual
knowledge or the Property Trustee's duties and obligations under this
Declaration or the Trust Indenture Act.

     (f) The Property Trustee shall continue to serve as a Trustee until either:

          (i) the Trust has been completely liquidated and the proceeds of the
          liquidation distributed to the Holders of Securities pursuant to the
          terms of the Securities; or

                                      17
<PAGE>
 
          (ii)  a Successor Property Trustee has been appointed and has accepted
          that appointment in accordance with Section 5.7.

     (g) The Property Trustee shall have the legal power to exercise all of the
rights, powers and privileges of a holder of Debentures under the Indenture and,
if an Event of Default actually known to a Responsible Officer of the Property
Trustee occurs and is continuing, the Property Trustee shall, for the benefit of
Holders of the Securities, enforce its rights, including, without limitation,
its rights under the Indenture as holder of the Debentures and its rights under
the Preferred Securities Guarantee in accordance with the terms of the Preferred
Securities Guarantee, subject to the rights of the Holders pursuant to the terms
of such Securities and the Preferred Securities Guarantee.

     (h) The Property Trustee may authorize one or more Persons (each, a "Paying
Agent") to pay Distributions, redemption payments or liquidation payments on
behalf of the Trust with respect to all Securities and any such Paying Agent
shall comply with Section 317(b) of the Trust Indenture Act.  Any Paying Agent
may be removed by the Property Trustee at any time and a successor Paying Agent
or additional Paying Agents may be appointed at any time by the Property
Trustee.  In the event the Preferred Securities do not remain in the form of one
or more Global Certificates, the Property Trustee will act as Paying Agent and
may designate an additional or substitute Paying Agent at any time.

     (i) Subject to this Section 3.8, the Property Trustee shall have none of
the duties, liabilities, powers or the authority of the Regular Trustees set
forth in Section 3.6.

The Property Trustee must exercise the powers set forth in this Section 3.8 in a
manner that is consistent with the purposes and functions of the Trust set out
in Section 3.3, and the Property Trustee shall not take any action that is
inconsistent with the purposes and functions of the Trust set out in Section
3.3.

     SECTION 3.9   Certain Duties and Responsibilities of the Property Trustee.
                   ----------------------------------------------------------- 

     (a) The Property Trustee, before the occurrence of any Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Declaration and no implied covenants shall be read into this Declaration against
the Property Trustee.  In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.6) of which a Responsible Officer of
the Property Trustee has actual knowledge, the Property Trustee shall exercise
such of the rights and powers vested in it by this Declaration, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of his or her own affairs.

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

                                      18
<PAGE>
 
          (i) prior to the occurrence of an Event of Default and after the
          curing or waiving of all such Events of Default that may have
          occurred:

               (A) the duties and obligations of the Property Trustee  shall be
     determined solely by the express provisions  of this Declaration and in the
     terms of the Securities and the Property Trustee shall not be liable except
     for the  performance of such duties and obligations as are specifically set
     forth in this Declaration, and no implied covenants or obligations shall be
     read into this Declaration against the  Property Trustee; and

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

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

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

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

          (v) the Property Trustee's sole duty with respect to the custody, safe
          keeping and physical preservation of the Debentures and the Property
          Trustee Account 

                                      19
<PAGE>
 
          shall be to deal with such property in a similar manner as the
          Property Trustee deals with similar property for its own account,
          subject to the protections and limitations on liability afforded to
          the Property Trustee under this Declaration and the Trust Indenture
          Act;

          (vi) the Property Trustee shall have no duty or liability for or with
          respect to the value, genuineness, existence or sufficiency of the
          Debentures or the payment of any taxes or assessments levied thereon
          or in connection therewith;

          (vii) the Property Trustee shall not be liable for any interest on any
          money received by it except as it may otherwise agree in writing with
          the Sponsor. Money held by the Property Trustee need not be segregated
          from other funds held by it except in relation to the Property Trustee
          Account maintained by the Property Trustee pursuant to Section
          3.8(c)(i) and except to the extent otherwise required by law; and

          (viii) the Property Trustee shall not be responsible for monitoring
          the compliance by the Regular Trustees or the Sponsor with their
          respective duties under this Declaration, nor shall the Property
          Trustee be liable for any default or misconduct of the Regular
          Trustees or the Sponsor.

          before taking, suffering or omitting any action hereunder, the
          Property Trustee (unless other evidence is herein specifically
          prescribed) may, in the absence of bad faith on its part, request and
          conclusively rely upon an Officers' Certificate which, upon

                                      20

          (v) before the Property Trustee acts or refrains from acting, the

          shall be full and complete  authorization and protection in respect of
          any action taken, suffered or omitted by it hereunder in good faith

          of the rights or powers vested in it by this Declaration at the

          satisfactory to the Property Trustee, against the costs, expenses
          (including attorneys' fees and expenses and expenses of the Property

          indebtedness or other paper or document, but the Property Trustee, in
          its discretion, may make such further inquiry or investigation into
          such facts or matters as it may see fit;

          (viii) the Property Trustee may execute any of the trusts or powers

<PAGE>
 
          responsible for any misconduct or negligence on the part of any agent
          or attorney appointed with due care by it hereunder;

          (ix) any action taken by the Property Trustee or its agents hereunder
          shall bind the Trust and the Holders of the Securities, and the
          signature of the Property Trustee or its agents alone shall be
          sufficient and effective to perform any such action and no third party
          shall be required to inquire as to the authority of the Property
          Trustee to so act or as to its compliance with any of the terms and
          provisions of this Declaration, both of which shall be conclusively
          evidenced by the Property Trustee's or its agent's taking such action;
          and

          the Securities which instructions may only be given by the Holders of
          the same proportion in liquidation amount of the Securities as would

          Securities in respect of such remedy, right or action; (ii) may
          refrain from enforcing such remedy or right or taking such other
          action until such instructions are received; and (iii) shall be

          surety in respect of the performance of its powers and duties

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

duties and responsibilities of the Regular Trustees or the Property Trustee

          respect to the Preferred Securities) are listed, or any Successor
          Securities (with respect to the Preferred Securities) will be listed
          upon notification of issuance, on any national securities exchange or
          with any other organization on which the Preferred Securities are then
          listed or quoted;

          (iv) such merger, consolidation, amalgamation or replacement does not
          cause the Preferred Securities (including any Successor Securities of
          the Preferred Securities) to be downgraded by any nationally
          recognized statistical rating organization then rating the Preferred
          Securities;

          (v) such merger, consolidation, amalgamation or replacement does not
          adversely affect the rights, preferences and privileges of the Holders
          of the Securities (including any Successor Securities) in any material
          respect (other than with respect to any dilution of such Holders'
          interests in the new entity);

          (vi) such Successor Entity has a purpose identical to that of the
          Trust;
 
          (vii) prior to such merger, consolidation, amalgamation or

          counsel to the Trust experienced in such matters to the effect that,

          respect (other than with respect to any dilution of Holders' interest
          in the new entity), (B) following such merger, amalgamation,
          consolidation or replacement, neither the Trust nor the successor
          entity will be required to register as an investment company under the
          Investment Company Act and (C) the Trust will continue to be
          classified as a grantor trust for federal income tax purposes;
 
          (viii) the Sponsor guarantees the obligations of such Successor Entity
          under the Successor Securities at least to the extent provided by the
          Preferred Securities Guarantee; and

                                      24
<PAGE>

          and the Property Trustee at least 5 Business Days' prior written
          notice of the consummation of such merger, consolidation, amalgamation
          or replacement; provided that failure to provide such notice shall not
          affect the validity of any such transaction.

     (c) Notwithstanding Section 3.15(b), the Trust shall not, except with the
consent of Holders of 100% in liquidation amount of  the Securities,
consolidate, amalgamate, merge with or into, or be replaced by any other entity
or permit any other entity to consolidate, amalgamate, merge with or into, or
replace it if such consolidation, amalgamation, merger or replacement would
cause the Trust or Successor Entity to be classified as other than a grantor
trust for United States federal income tax purposes and each Holder of the
Securities to be treated as owning an undivided beneficial interest in the
Debentures.

     SECTION 3.16  Property Trustee May File Proofs of Claim.  In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Trust or any other obligor upon the Securities or the
property of the Trust or of such other obligor or their creditors, the Property
Trustee (irrespective of whether any Distributions on the Securities shall then
be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Property Trustee shall have made any demand on the
Trust for the payment of any past due Distributions) shall be entitled and
empowered, to the fullest extent permitted by law, by intervention in such
proceeding or otherwise:

     (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Securities (or, if the Securities are
original issue discount Securities, such portion of the liquidation amount as
may be specified in the terms of such Securities) and to file such other papers
or documents as may be necessary or advisable in order to have the claims of the
Property Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel) and
of the Holders allowed in such judicial proceeding; and
 
     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;
 
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or

               (B) until the assets of the Trust have been completely liquidated
     and the proceeds thereof distributed to the holders of the Securities; and

     SECTION 5.8   Vacancies among Trustees.  If a Trustee ceases to hold office
for any reason and the number of Trustees is not reduced pursuant to Section 5.1
or Section 5.2, or if the number of Trustees is increased pursuant to Section
5.1, a vacancy shall occur.  A resolution certifying the existence of such
vacancy by the Regular Trustees or, if there are more than two, a majority of
the Regular Trustees shall be conclusive evidence of the existence of such
vacancy.  The vacancy shall be filled with a Trustee appointed in accordance
with Section 5.7.

     SECTION 5.9   Effect of Vacancies.  The death, resignation, retirement,
removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to
perform the duties of a Trustee shall not operate to annul, dissolve or
terminate the Trust.  Whenever a vacancy in the number of Regular Trustees shall
occur, until such vacancy is filled by the appointment of a Regular Trustee in
accordance with Section 5.7, the Regular Trustees in office, regardless of their
number, shall have all the powers granted to the Regular Trustees and shall
discharge all the duties imposed upon the Regular Trustees by this Declaration.

     SECTION 5.10   Meetings.  If there is more than one Regular Trustee,

person meetings of the Regular Trustees shall be hand delivered or otherwise
delivered in writing (including by facsimile, with a hard copy by overnight
courier) not less than 48 hours before such meeting.  Notice of any telephonic
meetings of the Regular Trustees shall be hand delivered or otherwise delivered
in writing (including by facsimile, with a hard copy by overnight courier) not
less than 24 hours before a meeting.  Notices shall contain a brief statement of
the time, place and anticipated purposes of the meeting.  The presence (whether
in person or by telephone) of a Regular Trustee at a meeting shall constitute a
waiver of notice of such meeting except where a Regular Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened.
Notwithstanding the foregoing, unless provided otherwise in this Declaration,
any action of the Regular Trustees may be authorized and taken by any one of the
Regular Trustees.  In the event there is only one Regular Trustee, any and all
action of such Regular Trustee shall be evidenced by a written consent of such
Regular Trustee.

     SECTION 5.11   Delegation of Power.
                   ------------------- 

     (a) Any Regular Trustee may, by power of attorney consistent with

its power for the purpose of executing any documents contemplated in Section
3.6, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing.

     (b) The Regular Trustees shall have power to delegate from time to time to
such of their number or to officers of the Trust the doing of such things and

Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

     SECTION 5.12  Merger, Conversion, Consolidation or Succession to Business.
Any Person into which the Property Trustee or the Delaware Trustee, as the case
may be, may be merged or converted or with which either may be consolidated, or
any Person resulting from any merger, conversion or consolidation to which the
Property Trustee or the Delaware Trustee, as the case may be, shall be a party,
or any Person succeeding to all or substantially all the corporate trust
business of the Property Trustee or the Delaware Trustee, as the case may be,
shall be the successor of the Property Trustee or the Delaware Trustee, as the
case may be, hereunder, provided such Person 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.

defined herein) in accordance with the applicable terms of the relevant Holder's
Securities.  Distributions shall be made on the Preferred Securities and the
Common Securities in accordance with the preferences set forth in their

payment of interest (including Compounded Interest (as defined in the Indenture)
and Additional Interest (as defined in the Indenture)), premium and/or principal
on the Debentures held by the Property Trustee (the amount of any such payment
being a "Payment Amount"), the Property Trustee shall and is directed, to the
extent funds are available for that purpose, to make a distribution (a
"Distribution") of the Payment Amount to Holders.

undivided beneficial interests in the assets of the Trust having such terms as
are set forth in Annex I, as such Annex I may be amended from time to time in
accordance with the provisions of this Declaration and one class of common
securities (the "Common Securities") representing undivided beneficial interests
in the assets of the Trust having such terms as are set forth in Annex I, as
such Annex I may be amended from time to time in accordance with the provisions
of this Declaration.  The Trust shall issue no securities or other interests in

     (b) The Certificates shall be signed on behalf of the Trust by a Regular
Trustee.  Such signature shall be the manual or facsimile signature of any
present or any future Regular Trustee. In case any Regular Trustee of the Trust
who shall have signed any of the Certificates shall cease to be such Regular
Trustee before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificate had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons who, at the actual date of
execution of such Certificate, shall be the Regular Trustees of the Trust,
although at the date of the execution and delivery of the Declaration any such
person was not such a Regular Trustee.  Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation of
any stock exchange on which Securities may be listed, or to conform to usage.
 
     (c) The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

     (d) Upon issuance of the Securities as provided in this Declaration, the
Securities so issued shall be deemed to be validly issued, fully paid and non-
assessable and shall not be subject to any preferential subscription or pre-
emptive rights (subject to Section 10.1(b) with respect to the Common
Securities).

     (e) Every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by, this Declaration and the terms of the Securities, the Preferred
Securities Guarantee, the Indenture and the Debentures.

          (iii) upon the entry of a decree of judicial dissolution of the Holder
          of the Common Securities, the Sponsor or the Trust;

          (iv) when all of the Securities shall have been called for redemption
          and the amounts necessary for redemption thereof shall have been paid
          to the Holders in accordance with the terms of the Securities;

          (v) the occurrence and continuation of a Special Event pursuant to
          which the Trust shall have been dissolved in accordance with the terms

          distributed to the Holders of Securities in exchange for all of the
          Securities;

Secretary of State of the State of Delaware and thereupon the Trust shall
terminate.

     SECTION 9.1   Transfer of Securities.
                   ---------------------- 

     (a) Securities may only be transferred, in whole or in part, in accordance
with the terms and conditions set forth in this Declaration and in the terms of
the Securities.  Any transfer or purported transfer of any Security not made in
accordance with this Declaration shall be null and void.

     (b) Subject to this Article IX, Preferred Securities shall be freely
transferable.

     (c) Subject to this Article IX, the Sponsor and any Related Party may only
transfer Common Securities to the Sponsor or a Related Party of the Sponsor;
provided that, any such 

                                      34
<PAGE>
 
transfer is subject to the condition precedent that the transferor obtain the
written opinion of qualified independent counsel experienced in such matters
that such transfer would not cause more than an insubstantial risk that:

          (i) the Trust would not be classified for United States federal income
          tax purposes as a grantor trust and each Holder of Securities would
          not be treated as owning an undivided beneficial interest in the
          Debentures; and

          (ii) the Trust would be an Investment Company or the transferee would
          become an Investment Company.

     SECTION 9.2   Transfer and Exchange of Certificates.  The Regular Trustees
shall provide for the registration of Certificates and of transfers or exchanges
of Certificates, which will be effected without charge but only upon payment
(with such indemnity as the Regular Trustees may require) in respect of any tax
or other government charges that may be imposed in relation to it. Upon
surrender for registration of transfer of any Certificate, the Regular Trustees
shall cause one or more new Certificates to be issued in the name of the
designated transferee or transferees.  Upon surrender for exchange of any
Certificate, the Regular Trustees shall cause one or more new Certificates in
the same aggregate liquidation amount as the Certificate surrendered for
exchange to be issued in the name of the Holder of the Certificate so
surrendered.  Every Certificate surrendered for registration of transfer or for
exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Regular Trustees duly executed by the Holder or such
Holder's attorney duly authorized in writing.  Each Certificate surrendered for
registration of transfer or for exchange shall be canceled by the Regular
Trustees.  A transferee of a Certificate shall be entitled to the rights and
subject to the obligations of a Holder hereunder upon the receipt by such
transferee of a Certificate.  By acceptance of a Certificate, each transferee
shall be deemed to have agreed to be bound by this Declaration.

     SECTION 9.3   Deemed Security Holders.  The Trustees may treat the Person
in whose name any Certificate shall be registered on the books and records of
the Trust as the sole holder of such Certificate and of the Securities
represented by such Certificate for purposes of receiving Distributions and for
all other purposes whatsoever and, accordingly, shall not be bound to recognize
any equitable or other claim to or interest in such Certificate or in the
Securities represented by such Certificate on the part of any Person, whether or
not the Trust shall have actual or other notice thereof.

     SECTION 9.4   Book Entry Interests.  Unless otherwise specified in the
terms of the Preferred Securities, the Preferred Securities Certificates, on
original issuance, will be issued in the form of one or more fully registered,
global Preferred Security Certificates (each, a "Global Certificate"), to be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust.
Such Global Certificates shall initially be registered on the books and records
of the Trust in the name of Cede & Co., the nominee of DTC, and no Preferred
Security Beneficial Owner will receive a definitive Preferred Security
Certificate representing such Preferred Security Beneficial Owner's 

                                      35

interests in such Global Certificates, except as provided in Section 9.7. Unless
and until definitive, fully registered Preferred Security Certificates (the
"Definitive Preferred Security Certificates") have been issued to the Preferred
Security Beneficial Owners pursuant to Section 9.7:

     (a) the provisions of this Section 9.4 shall be in full force and effect;

     (b) the Trust and the Trustees shall be entitled to deal with the Clearing
Agency for all purposes of this Declaration (including the payment of
Distributions on the Global Certificates and receiving approvals, votes or
consents hereunder) as the Holder of the Preferred Securities and the sole
holder of the Global Certificates and shall have no obligation to the Preferred
Security Beneficial Owners;

     (c) to the extent that the provisions of this Section 9.4 conflict with any
other provisions of this Declaration, the provisions of this Section 9.4 shall
control; and

     (d) the rights of the Preferred Security Beneficial Owners shall be
exercised only through the Clearing Agency and shall be limited to those
established by law and agreements between such Preferred Security Beneficial
Owners and the Clearing Agency and/or the Clearing Agency Participants.  DTC
will make book entry transfers among the Clearing Agency Participants and
receive and transmit payments of Distributions on the Global Certificates to
such Clearing Agency Participants.

     SECTION 9.5   Notices to Clearing Agency.  Whenever a notice or other
communication to the Preferred Security Holders is required under this
Declaration, unless and until Definitive Preferred Security Certificates shall
have been issued to the Preferred Security Beneficial Owners pursuant to Section
9.7, the Regular Trustees or the Property Trustee, if the Property Trustee is
specifically required to give such notice, shall give all such notices and
communications specified herein to be given to the Preferred Security Holders to
the Clearing Agency, and shall have no notice obligations to the Preferred
Security Beneficial Owners.

     SECTION 9.6   Appointment of Successor Clearing Agency.  If any Clearing
Agency elects to discontinue its services as securities depository with respect
to the Preferred Securities or if the Regular Trustees elect to have another
Clearing Agency serve as securities depository with respect to the Preferred
Securities, the Regular Trustees may, in their sole discretion, appoint a
successor Clearing Agency with respect to such Preferred Securities.

     SECTION 9.7   Definitive Preferred Security Certificates.  If:
                   ------------------------------------------      

     (a) a Clearing Agency elects to discontinue its services as securities
depository with respect to the Preferred Securities and a successor Clearing
Agency is not appointed within 90 days after such discontinuance pursuant to
Section 9.6; or

                                      36
<PAGE>
 
     (b) the Regular Trustees elect after consultation with the Sponsor to
terminate the book entry system through the Clearing Agency with respect to the
Preferred Securities, then:

          (i) Definitive Preferred Security Certificates shall be prepared by
          the Regular Trustees on behalf of the Trust with respect to such
          Preferred Securities; and

          (ii) upon surrender of the Global Certificates by the Clearing Agency,
          accompanied by registration instructions, the Regular Trustees shall
          cause Definitive Preferred Security Certificates to be delivered to
          the Preferred Security Beneficial Owners in accordance with the
          instructions of the Clearing Agency.  Neither the Trustees nor the
          Trust shall be liable for any delay in delivery of such instructions
          and each of them may conclusively rely on, and shall be protected in
          relying on, said instructions of the Clearing Agency.  The Definitive
          Preferred Security Certificates shall be printed, lithographed or
          engraved or may be produced in any other manner as is reasonably
          acceptable to the Regular Trustees, as evidenced by their execution
          thereof, and may have such letters, numbers or other marks of
          identification or designation and such legends or endorsements as the
          Regular Trustees may deem appropriate, or as may be required to comply
          with any law or with any rule or regulation made pursuant thereto or
          with any rule or regulation of any stock exchange on which Preferred
          Securities may be listed, or to conform to usage.

     SECTION 9.8   Mutilated, Destroyed, Lost or Stolen Certificates.  If:
                   -------------------------------------------------      

     (a) any mutilated Certificates should be surrendered to the Regular
Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and

     (b) there shall be delivered to the Regular Trustees such security or
indemnity as may be required by them to keep each of them, the Sponsor and the
Trust harmless, then, in the absence of notice that such Certificate shall have
been acquired by a protected purchaser, any Regular Trustee on behalf of the
Trust shall execute and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
denomination.  In connection with the issuance of any new Certificate under this
Section 9.8, the Regular Trustees may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.  Any duplicate Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the relevant
Securities, as if originally issued, whether or not the lost, stolen or
destroyed Certificate shall be found at any time.

                           LIMITATION OF LIABILITY OF
                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

     SECTION 10.1   Liability.
                    --------- 

     (a) Except as expressly set forth in this Declaration, the Debentures, the
Preferred Securities Guarantee and the terms of the Securities, the Sponsor
shall not be:

          (i) personally liable for the return of any portion of the capital
          contributions (or any return thereon) of the Holders of the Securities
          which shall be made solely from assets of the Trust; and

          (ii) be required to pay to the Trust or to any Holder of Securities
          any deficit upon dissolution of the Trust or otherwise.

     (b) The Sponsor shall be liable for all of the debts and obligations of the
Trust (other than with respect to the Securities) to the extent not satisfied
out of the Trust's assets.

     (c) Pursuant to Section 3803(a) of the Business Trust Act, the Holders of
the Preferred Securities shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

     SECTION 10.2  Exculpation.
                   ----------- 

     (a) No Indemnified Person shall be liable, responsible or accountable in
damages or otherwise to the Trust or any Covered Person for any loss, damage or
claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Trust and in a manner such
Indemnified Person reasonably believed to be within the scope of the authority
conferred on such Indemnified Person by this Declaration or by law, except that
an Indemnified Person shall be liable for any such loss, damage or claim
incurred by reason of such Indemnified Person's gross negligence (ordinary
negligence in the case of the Property Trustee) or willful misconduct with
respect to such acts or omissions.

     (b) An Indemnified Person shall be fully protected in relying in good faith
upon the records of the Trust and upon such information, opinions, reports or
statements presented to the Trust by any Person as to matters the Indemnified
Person reasonably believes are within such other Person's professional or expert
competence and who has been selected with reasonable care by or on behalf of the
Trust, including information, opinions, reports or statements as to the value
and amount of the assets, liabilities, profits, losses or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

     SECTION 10.3  Fiduciary Duty.
                   -------------- 

     (a) To the extent that, at law or in equity, an Indemnified Person has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to any Covered Person, an Indemnified Person acting under this
Declaration shall not be liable to the Trust or to any Covered Person for its
good faith reliance on the provisions of this Declaration.  The provisions of
this Declaration, to the extent that they restrict the duties and liabilities of
an Indemnified Person otherwise existing at law or in equity (other than the
duties imposed on the Property Trustee under the Trust Indenture Act), are
agreed by the parties hereto to replace such other duties and liabilities of
such Indemnified Person.

     (b) Unless otherwise expressly provided herein:

          (i) whenever a conflict of interest exists or arises between any
          Covered Persons; or

          (ii) whenever this Declaration or any other agreement contemplated
          herein or therein provides that an Indemnified Person shall act in a
          manner that is, or provides terms that are, fair and reasonable to the
          Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices and any applicable generally accepted accounting
practices or principles.  In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise; and

     (c) Whenever in this Declaration an Indemnified Person is permitted or
required to make a decision:

          (i) in its "discretion" or under a grant of similar authority, the
          Indemnified Person shall be entitled to consider such interests and
          factors as it desires, including its own interests, and shall have no
          duty or obligation to give any consideration to any interest of or
          factors affecting the Trust or any other Person; or

          (ii) in its "good faith" or under another express standard, the
          Indemnified Person shall act under such express standard and shall not
          be subject to any other or different standard imposed by this
          Declaration or by applicable law.

     SECTION 10.4  Indemnification and Compensation.
                   -------------------------------- 

     (a)  (i)  The Sponsor shall indemnify, to the fullest extent permitted by
          law, any Company Indemnified Person who was or is a party or is
          threatened to be made a party to any threatened, pending or completed
          action, suit or proceeding, whether civil, criminal, administrative or
          investigative (other than an action by or in the right of the Trust)
          by reason of the fact that he is or was a Company Indemnified Person
          against expenses (including attorneys' fees), judgments, fines and
          amounts paid in settlement actually and reasonably incurred by him in
          connection with such action, suit or proceeding if he acted in good
          faith and in a manner he reasonably believed to be in or not opposed
          to the best interests of the Trust, and, with respect to any criminal
          action or proceeding, had no reasonable cause to believe his conduct
          was unlawful. The termination of any action, suit or proceeding by
          judgment, order, settlement, conviction or upon a plea of nolo
          contendere or its equivalent, shall not, of itself, create a
          presumption that the Company Indemnified Person did not act in good
          faith and in a manner which he reasonably believed to be in or not
          opposed to the best interests of the Trust, and, with respect to any
          criminal action or proceeding, had reasonable cause to believe that
          his conduct was unlawful.

          (ii) The Sponsor shall indemnify, to the fullest extent permitted by
          law, any Company Indemnified Person who was or is a party or is
          threatened to be made a party to any threatened, pending or completed
          action or suit by or in the right of the Trust to procure a judgment
          in its favor by reason of the fact that he is or was a Company
          Indemnified Person against expenses (including attorneys' fees)
          actually and reasonably incurred by him in connection with the defense
          or settlement of such action or suit if he acted in good faith and in
          a manner he reasonably believed to be in or not opposed to the best
          interests of the Trust and except that no such indemnification shall
          be made in respect of any claim, issue or matter as to which such
          Company Indemnified Person shall have been adjudged to be liable to
          the Trust unless and only to the extent that the Court of Chancery of
          Delaware or the court in which such action or suit was brought shall
          determine upon application that, despite the adjudication of liability
          but in view of all the circumstances of the case, such person is
          fairly and reasonably entitled to indemnity for such expenses which
          such Court of Chancery or such other court shall deem proper.

          (iii) Any indemnification under paragraphs (i) and (ii) of this
          Section 10.4(a) (unless ordered by a court) shall be made by the
          Sponsor only as authorized in the specific case upon a determination
          that indemnification of the Company Indemnified Person is proper in
          the circumstances because he has

                                      40
<PAGE>
 
          met the applicable standard of conduct set forth in paragraphs (i) and
          (ii). Such determination shall be made (1) by the Regular Trustees by
          a majority vote of a quorum consisting of such Regular Trustees who
          were not parties to such action, suit or proceeding, (2) if such a
          quorum is not obtainable, or, even if obtainable, if a quorum of
          disinterested Regular Trustees so directs, by independent legal
          counsel in a written opinion or (3) by the Common Security Holder of
          the Trust.

          (iv) Expenses (including attorneys' fees) incurred by a Company
          Indemnified Person in defending a civil, criminal, administrative or
          investigative action, suit or proceeding referred to in paragraphs (i)
          and (ii) of this Section 10.4(a) shall be paid by the Sponsor in
          advance of the final disposition of such action, suit or proceeding
          upon receipt of an undertaking by or on behalf of such Company
          Indemnified Person to repay such amount if it shall ultimately be
          determined that he is not entitled to be indemnified by the Sponsor as
          authorized in this Section 10.4(a).  Notwithstanding the foregoing, no
          advance shall be made by the Sponsor if a determination is reasonably
          and promptly made (i) by the Regular Trustees by a majority vote of a
          quorum of disinterested Regular Trustees, (ii) if such a quorum is not
          obtainable, or, even if obtainable, if a quorum of disinterested
          Regular Trustees so directs, by independent legal counsel in a written
          opinion or (iii) the Common Security Holder of the Trust, that, based
          upon the facts known to the Regular Trustees, counsel or the Common
          Security Holder at the time such determination is made, such Company
          Indemnified Person acted in bad faith or in a manner that such person
          did not believe to be in or not opposed to the best interests of the
          Trust, or, with respect to any criminal proceeding, that such Company
          Indemnified Person believed or had reasonable cause to believe his
          conduct was unlawful.  In no event shall any advance be made in
          instances where the Regular Trustees, independent legal counsel or
          Common Security Holder reasonably determine that such person
          deliberately breached his duty to the Trust or its Common or Preferred
          Security Holders.

          (v) The indemnification and advancement of expenses provided by, or
          granted pursuant to, the other paragraphs of this Section 10.4(a)
          shall not be deemed exclusive of any other rights to which those
          seeking indemnification and advancement of expenses may be entitled
          under any agreement, vote of stockholders or disinterested directors
          of the Debenture Issuer or Preferred Security Holders of the Trust or
          otherwise, both as to action in his official capacity and as to action
          in another capacity while holding such office.  All rights to
          indemnification under this Section 10.4(a) shall be deemed to be
          provided by a contract between the Debenture Issuer and each Company
          Indemnified Person who serves in such capacity at any time while this

                                      41
<PAGE>
 
          Section 10.4(a) is in effect.  Any repeal or modification of this
          Section 10.4(a) shall not affect any rights or obligations then
          existing.

          (vi) The Debenture Issuer or the Trust may purchase and maintain
          insurance on behalf of any person who is or was a Company Indemnified
          Person against any liability asserted against him and incurred by him
          in any such capacity, or arising out of his status as such, whether or
          not the Debenture Issuer would have the power to indemnify him against
          such liability under the provisions of this Section 10.4(a).

          (vii) For purposes of this Section 10.4(a), references to "the Trust"
          shall include, in addition to the resulting or surviving entity, any
          constituent entity (including any constituent of a constituent)
          absorbed in a consolidation or merger, so that any person who is or
          was a director, trustee, officer or employee of such constituent
          entity, or is or was serving at the request of such constituent entity
          as a director, trustee, member, partner, officer, employee or agent of
          another entity, shall stand in the same position under the provisions
          of this Section 10.4(a) with respect to the resulting or surviving
          entity as he would have with respect to such constituent entity if its
          separate existence had continued.

          (viii) The indemnification and advancement of expenses provided by, or
          granted pursuant to, this Section 10.4(a) shall, unless otherwise
          provided when authorized or ratified, continue as to a person who has
          ceased to be a Company Indemnified Person and shall inure to the
          benefit of the heirs, executors and  administrators of such a person.
          The obligation to indemnify as set forth in this Section 10.4(a) shall
          survive the satisfaction and discharge of this Declaration.

     (b) The Debenture Issuer agrees to indemnify the (i) Property Trustee, (ii)
the Trust Company and the Delaware Trustee, (iii) any Affiliate of the Property
Trustee, the Trust Company and the Delaware Trustee and (iv) any officers,
directors, shareholders, members, partners, employees, representatives,
custodians, nominees or agents of the Property Trustee, the Trust Company and
the Delaware Trustee (each of the Persons in (i) through (iv) being referred to
as a "Fiduciary Indemnified Person") for, and to hold each Fiduciary Indemnified
Person harmless against, any loss, liability or expense incurred without
negligence (or in the case of the Trust Company or the Delaware Trustee, gross
negligence) or bad faith on its part, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder or the performance
hereof or exercise of its rights hereunder, including the costs and expenses
(including reasonable legal fees and expenses) of defending itself against or
investigating any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The obligation to
indemnify as set forth in this Section 10.4(b) shall survive the satisfaction
and discharge of this Declaration and the resignation or removal as Trustee of
any Fiduciary Indemnified Person.

                                      42
<PAGE>
 
     (c) The Debenture Issuer shall pay to the Property Trustee from time to
time such reasonable compensation for its services as the Company and the
Property Trustee shall agree in writing from time to time.  The Property
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  The Debenture Issuer agrees to indemnify and
defend the Property Trustee, the Trust Company and the Delaware Trustee and
their respective directors, officers, employees or agents for, and to hold each
of them harmless against, any loss, liability or expense incurred without
negligence (or in the case of the Trust Company or the Delaware Trustee, gross
negligence) or bad faith on the part of the Property Trustee, the Trust Company,
the Delaware Trustee or such other Person, as the case may be, arising out of or
in connection with the acceptance or administration of the Trust or the
performance hereof or exercise of rights hereunder, including the costs and
expenses (including reasonable legal fees) of defending either of them against
or investigating any claim or liability in connection with the exercise of
performance of any of their respective powers or duties hereunder; the
provisions of this Section 10.4(c) shall survive the resignation or removal of
the Delaware Trustee or the Property Trustee or the termination of this
Declaration

     SECTION 10.5  Outside Businesses.  Any Covered Person, the Sponsor, the
Trust Company, the Delaware Trustee, the Regular Trustees and the Property
Trustee may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Trust, and the Trust and the Holders of Securities shall
have no rights by virtue of this Declaration in and to such independent ventures
or the income or profits derived therefrom, and the pursuit of any such venture,
even if competitive with the business of the Trust, shall not be deemed wrongful
or improper.  No Covered Person, the Sponsor, the Trust Company, the Delaware
Trustee, the Regular Trustees or the Property Trustee shall be obligated to
present any particular investment or other opportunity to the Trust even if such
opportunity is of a character that, if presented to the Trust, could be taken by
the Trust, and any Covered Person, the Sponsor, the Trust Company, the Delaware
Trustee, the Regular Trustees and the Property Trustee shall have the right to
take for its own account (individually or as a partner or fiduciary) or to
recommend to others any such particular investment or other opportunity.  Any
Covered Person, the Trust Company, the Delaware Trustee, the Regular Trustees
and the Property Trustee may engage or be interested in any financial or other
transaction with the Sponsor or any Affiliate of the Sponsor, or may act as
depository for, trustee or agent for, or act on any committee or body of holders
of, securities or other obligations of the Sponsor or its Affiliates.

                                   ACCOUNTING

     SECTION 11.1  Fiscal Year.  The fiscal year ("Fiscal Year") of the Trust
shall be the calendar year, or such other year as is required by the Code.

     SECTION 11.2  Certain Accounting Matters.
                   -------------------------- 

     (a) At all times during the existence of the Trust, the Regular Trustees
shall keep, or cause to be kept, full books of account, records and supporting
documents, which shall reflect in reasonable detail, each transaction of the
Trust.  The books of account shall be maintained on the 

                                      43
<PAGE>
 
accrual method of accounting, in accordance with generally accepted accounting
principles. The Trust shall use the accrual method of accounting for United
States federal income tax purposes. The books of account and the records of the
Trust shall be examined by and reported upon as of the end of each Fiscal Year
of the Trust by a firm of independent certified public accountants selected by
the Regular Trustees.

     (b) The Regular Trustees shall cause to be duly prepared and delivered to
each of the Holders of Securities, any annual United  States federal income tax
information statement, required by the Code, containing such information with
regard to the Securities held by each Holder as is required by the Code and the
Treasury Regulations.  Notwithstanding any right under the Code to deliver any
such statement at a later date, the Regular Trustees shall endeavor to deliver
all such statements within 30 days after the end of each Fiscal Year of the
Trust.

     (c) The Regular Trustees shall cause to be duly prepared and filed with the
appropriate taxing authority, an annual United States federal income tax return,
on a Form 1041 or such other form required by United States federal income tax
law, and any other annual income tax returns required to be filed by the Regular
Trustees on behalf of the Trust with any state or local taxing authority.

     SECTION 11.3  Banking.  The Trust shall maintain one or more bank accounts
in the name and for the sole benefit of the Trust; provided, however, that all
payments of funds in respect of the Debentures held by the Property Trustee
shall be made directly to the Property Trustee Account and no other funds of the
Trust shall be deposited in the Property Trustee Account.  The sole signatories
for such accounts shall be designated by the Regular Trustees; provided,
however, that the Property Trustee shall designate the signatories for the
Property Trustee Account.

     SECTION 11.4  Withholding.  The Trust and the Regular Trustees shall comply
with all withholding requirements under United States federal, state and local
law.  The Trust shall request, and the Holders shall provide to the Trust, such
forms or certificates as are necessary to establish an exemption from
withholding with respect to each Holder, and any representations and forms as
shall reasonably be requested by the Trust to assist it in determining the
extent of, and in fulfilling, its withholding obligations.  The Regular Trustees
shall file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, shall remit amounts
withheld with respect to the Holder to applicable jurisdictions.  To the extent
that the Trust is required to withhold and pay over any amounts to any authority
with respect to distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder.  In the event of any claim over withholding, Holders shall be limited to
an action against the applicable jurisdiction.  If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.  To the extent the
Property Trustee performs the functions provided for in this section, the
Regular Trustees shall direct the Property Trustee in carrying out such
functions.

     SECTION 12.2   Meetings of the Holders of Securities; Action by Written
                   --------------------------------------------------------
Consent.
- ------- 

     (a) Meetings of the Holders of any class of Securities may be called at any
time by the Regular Trustees (or as provided in the terms of the Securities) to
consider and act on any matter on which Holders of such class of Securities are
entitled to act under the terms of this Declaration, the terms of the Securities
or the rules of any stock exchange on which the Preferred Securities are listed
or admitted for trading.  The Regular Trustees shall call a meeting of the
Holders of such class if directed to do so by the Holders of at least 10% in
Liquidation Amount of such class of Securities. Such direction shall be given by
delivering to the Regular Trustees one or more calls in a writing stating that
the signing Holders of Securities wish to call a meeting and indicating the
general or specific purpose for which the meeting is to be called.  Any Holders
of Securities calling a meeting shall specify in writing the Certificates held
by the Holders of Securities exercising the right to call a meeting and only
those Securities specified shall be counted for purposes of determining whether
the required percentage set forth in the second sentence of this paragraph has
been met.

     (b) Except to the extent otherwise provided in the terms of the Securities,
the following provisions shall apply to meetings of Holders of Securities:

          (i) notice of any such meeting shall be given to all the Holders of
          Securities having a right to vote thereat at least 7 days and not more
          than 60 days before the date of such meeting.  Whenever a vote,
          consent or approval of the Holders of Securities is permitted or
          required under this Declaration or the rules of any stock exchange on
          which the Preferred Securities are listed or admitted for trading,
          such vote, consent or approval may be given at a meeting of the
          Holders of Securities.  Any action that may be taken at a meeting of
          the Holders of Securities may be taken without a meeting if a consent
          in writing setting forth the action so taken is signed by the Holders
          of Securities owning not less than the minimum amount of Securities in
          liquidation amount that would be necessary to authorize or take such
          action at a meeting at which all Holders of Securities having a right
          to vote thereon were present and voting.  Prompt notice of the taking
          of action without a meeting shall be given to the Holders of
          Securities entitled to vote who have not consented in writing.  The
          Regular Trustees may specify that any written ballot submitted to the
          Security Holders for the purpose of taking any action without a
          meeting shall be returned to the Trust within the time specified by
          the Regular Trustees;

          (ii) each Holder of a Security may authorize any Person to act for it
          by proxy on all matters in which a Holder of Securities is entitled to
          participate, including waiving notice of any meeting, or voting or
          participating at a meeting.  No proxy shall be valid after the
          expiration of 11 months from the date thereof unless otherwise
          provided in the proxy.  Every proxy shall be revocable at the pleasure
          of the Holder of Securities executing such proxy.  Except as 

                                      47
<PAGE>
 
          otherwise provided herein, all matters relating to the giving, voting
          or validity of proxies shall be governed by the General Corporation
          Law of the State of Delaware relating to proxies, and judicial
          interpretations thereunder, as if the Trust were a Delaware
          corporation and the Holders of the Securities were stockholders of a
          Delaware corporation;

          (iii) each meeting of the Holders of the Securities shall be conducted
          by the Regular Trustees or by such other Person that the Regular
          Trustees may designate; and

          (iv) unless the Business Trust Act, this Declaration, the terms of the
          Securities, the Trust Indenture Act or the listing rules of any stock
          exchange on which the Preferred Securities are then listed for
          trading, otherwise provides, the Regular Trustees, in their sole
          discretion, shall establish all other provisions relating to meetings
          of Holders of Securities, including notice of the time, place or
          purpose of any meeting at which any matter is to be voted on by any
          Holders of Securities, waiver of any such notice, action by consent
          without a meeting, the establishment of a record date, quorum
          requirements, voting in person or by proxy or any other matter with
          respect to the exercise of any such right to vote.

ANNEX I

TERMS OF
       _______% TRUST ORIGINATED PREFERRED SECURITIES
       _______% TRUST ORIGINATED COMMON SECURITIES

     Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust,
dated as of February __, 1999 (as amended from time to time, the "Declaration"),
the designation, rights, privileges, restrictions, preferences and other terms
and provisions of the Preferred Securities and Common Securities are set forth
below (each capitalized term used but not defined herein having the meaning set
forth in the Declaration or, if not defined in the Declaration, as defined in
the Prospectus referred to below):

1.   Designation and Number.
     ---------------------- 

     (a) PREFERRED SECURITIES.  Up to 20,000,000 Preferred Securities of the
Trust with an aggregate liquidation amount with respect to the assets of the
Trust of up to Five Hundred Million Dollars ($500,000,000) and a liquidation
amount with respect to the assets of the Trust of $25 per Preferred Security,
are hereby designated for the purposes of identification only as "___% Trust
Originated Preferred Securities/SM/('TOPrS'/SM/)" (the "Preferred Securities").
The Preferred Security Certificates evidencing the Preferred Securities shall be
substantially in the form of Exhibit A-1 to the Declaration, with such changes
and additions thereto or deletions therefrom as may be required by ordinary
usage, custom or practice or to conform to the rules of any stock exchange on
which the Preferred Securities are listed.

     (b) COMMON SECURITIES.  Up to 618,557 Common Securities of the Trust with
an aggregate liquidation amount with respect to the assets of the Trust of up to
Fifteen Million Four Hundred Sixty-Three Thousand Nine Hundred Twenty-Five
Dollars ($15,463,925) and a liquidation amount with respect to the assets of the
Trust of $25 per Common Security, are hereby designated for the purposes of
identification only as "___% Trust Originated Common Securities" (the "Common
Securities").  The Common Security Certificates evidencing the Common Securities
shall be substantially in the form of Exhibit A-2 to the Declaration, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice.

2.   Distributions.
     ------------- 

     (a) Distributions payable on each Security will be fixed at a rate per
annum of ____% (the "Coupon Rate") of the stated liquidation amount of $25 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee.  Distributions in arrears will bear interest
thereon from and including the last day of such quarter at the Coupon Rate
compounded quarterly (to the extent permitted by applicable law).  The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated.  A Distribution is payable only to the
extent that payments are made in respect of the Debentures held 

                                      53
<PAGE>
 
by the Property Trustee and to the extent the Property Trustee has funds
available therefor. The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 90-day quarter.

     (b) Distributions on the Securities will be cumulative, will accrue from
February ____, 1999, and will be payable quarterly in arrears, on March 31, June
30, September 30 and December 31 of each year, commencing on
___________________, 1999, except as otherwise described below.  The Debenture
Issuer has the right under the Indenture to defer payments of interest on the
Debentures by extending the interest payment period at any time and from time to
time for a period not exceeding 20 consecutive quarters (each such period, an
"Extension Period"), during which Extension Period no interest shall be due and
payable on the Debentures, provided that no Extension Period shall last beyond
the date of maturity of the Debentures.  As a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Coupon Rate compounded quarterly during any
such Extension Period.  Prior to the termination of any such Extension Period,
the Debenture Issuer may further extend such Extension Period, provided that
such Extension Period, together with all such previous and further extensions
thereof, may not exceed 20 consecutive quarters and may not extend beyond the
date of maturity of the Debentures.  Payments of deferred Distributions will be
payable to Holders of record of the Securities as they appear on the books and
records of the Trust on the record date for Distributions due at the end of such
Extension Period.  Upon the termination of any Extension Period and the payment
of all amounts then due, the Debenture Issuer may commence a new Extension
Period, subject to the above requirements.

     (c) Distributions on the Securities will be payable to the Holders thereof
as they appear on the books and records of the Trust on the relevant record
dates.  While the Preferred Securities remain in global form, the relevant
record dates shall be one Business Day prior to the relevant payment dates which
payment dates correspond to the interest payment dates on the Debentures.
Subject to any applicable laws and regulations and the provisions of the
Declaration, each such payment in respect of the Preferred Securities will be
made as described under the heading "Description of the Preferred Securities --
Book-Entry Issuance -- The Depository Trust Company" in the Prospectus dated
February ___, 1999 (the "Prospectus") included in the Registration Statement on
Form S-3 of the Sponsor and the Trust.  The relevant record dates for the Common
Securities shall be the same record date as for the Preferred Securities.  If
the Preferred Securities shall not continue to remain in global form, the
relevant record dates for the Preferred Securities shall conform to the rules of
any securities exchange on which the Preferred Securities are listed and, if
none, shall be selected by the Regular Trustees, which dates shall be at least
ten Business Days but less than 60 Business Days before the relevant payment
dates, which payment dates correspond to the interest payment dates on the
Debentures.  Distributions payable on any Securities that are not punctually
paid on any Distribution payment date, as a result of the Debenture Issuer
having failed to make a payment under the Debentures, will cease to be payable
to the Person in whose name such Securities are registered on the relevant
record date, and such defaulted Distribution will instead be payable 

                                      54
<PAGE>
 
to the Person in whose name such Securities are registered on the special record
date or other specified date determined in accordance with the Indenture. If any
date on which Distributions are payable on the Securities is not a Business Day,
then payment of the Distribution payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in then next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

     (d) In the event that there is any money or other property held by or for
the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

3.   Liquidation Distribution Upon Dissolution.
     ----------------------------------------- 

     (a) In the event of any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Trust, the Holders of the Securities on the
date of the liquidation, dissolution, winding-up or termination, as the case may
be, will be entitled to receive solely out of the assets of the Trust available
for distribution to Holders of Securities, after satisfaction of all claims and
obligations of the Trust in accordance with Section 3808(e) of the Business
Trust Act, an amount equal to the aggregate of the stated liquidation amount of
$25 per Security plus accrued and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"), unless, in
connection with such liquidation, dissolution, winding-up or termination,
Debentures in an aggregate principal amount equal to the aggregate stated
liquidation amount of such Securities, with an interest rate equal to the Coupon
Rate of, and bearing accrued and unpaid interest in an amount equal to the
accrued and unpaid Distributions on, such Securities, shall be distributed on a
Pro Rata basis to the Holders of the Securities in exchange for such Securities
in accordance with Section 4(e) hereof.

     (b) If, upon any such dissolution, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Securities shall be paid on a Pro Rata basis.

4.   Redemption and Distribution.
     --------------------------- 
     (a) Upon the repayment of the Debentures in whole or in part, whether at
maturity or upon acceleration, redemption (such redemption being either at the
option of the Debenture Issuer on or after ____________________, 2004 or at the
option of the Debenture Issuer in connection with the occurrence of a Special
Event as described below) or otherwise, the proceeds from such repayment or
redemption shall be simultaneously applied to redeem Securities having an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so repaid or redeemed at a redemption price of $25 per Security plus
an amount equal to accrued and unpaid Distributions thereon at the date of the
redemption, payable in cash (the "Redemption Price").  Holders will be 

                                      55
<PAGE>
 
given not less than 30 nor more than 60 days notice of such redemption, except
in the case of payments upon maturity.

     (b) If fewer than all the outstanding Securities are to be so redeemed, the
Common Securities and the Preferred Securities will be redeemed Pro Rata and the
Preferred Securities to be redeemed will be as described in Section 4(f)(ii)
below.

     (c) If, at any time, a Tax Event or an Investment Company Event (each as
defined below, and each a "Special Event") shall occur and be continuing, the
Debenture Issuer shall have the right, upon not less than 30 nor more than 60
days notice, to redeem the Debentures in whole or in part for cash within 90
days following the occurrence of such Special Event, and, following such
redemption, Securities with an aggregate liquidation amount equal to the
aggregate principal amount of the Debentures so redeemed shall be redeemed by
the Trust at the Redemption Price on a Pro Rata basis in accordance with Section
8 hereof.  The Common Securities will be redeemed Pro Rata with the Preferred
Securities, except that if an Event of Default has occurred and is continuing,
the Preferred Securities will have priority over the Common Securities with
respect to payment of the Redemption Price.

     "Tax Event" means that the Regular Trustees shall have received an opinion
of an independent tax counsel experienced in such matters to the effect that, as
a result of (i) any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, or (ii) any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
such pronouncement or decision is announced on or after the date of original
issuance of the Preferred Securities, there is more than an insubstantial risk
that (A) the Trust is, or will be within 90 days after the date thereof, subject
to United States federal income tax with respect to interest accrued or received
on the Debentures, (B) the Trust is, or will be within 90 days after the date
thereof, subject to more than a de minimis amount of taxes, duties or other
governmental charges or (C) interest payable by the Debenture Issuer to the
Trust on the Debentures is not, or within 90 days of the date thereof, will not
be deductible, in whole or in part, by the Debenture Issuer for United States
federal income tax purposes.

     "Investment Company Event" means that the Regular Trustees shall have
received an opinion of an independent counsel experienced in practice under the
Investment Company Act to the effect that, as a result of the occurrence of a
change in law or regulation or a change in interpretation or application of law
or regulation by any legislative body, court, governmental agency or regulatory
authority(a "Change in 1940 Act Law"), there is a more than an insubstantial
risk that the Trust is or will be considered an "investment company" which is
required to be registered under the Investment Company Act, which Change in 1940
Act Law becomes effective on or after the date of original issuance of the
Preferred Securities.

                                      56
<PAGE>
 
     (d) The Trust may not redeem fewer than all the outstanding Securities
unless all accrued and unpaid Distributions have been paid on all Securities for
all quarterly Distribution periods terminating on or before the date of
redemption.

     (e) In the event that the Sponsor makes the election referred to in Section
8.1(a)(v) of the Declaration, the Regular Trustees shall dissolve the Trust and,
after satisfaction of creditors, cause Debentures, held by the Property Trustee,
having an aggregate principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on and having the
same record date for payment, as the Securities, to be distributed to the
Holders of the Securities in liquidation

of such Holders' interests in the Trust on a Pro Rata basis in accordance with
Section 8 hereof.  On and from the date fixed by the Regular Trustees for any
distribution of Debentures and dissolution of the Trust: (i) the Securities will
no longer be deemed to be outstanding and (ii) the Clearing Agency or its
nominee (or any successor Clearing Agency or its nominee) will receive one or
more global certificate or certificates representing the Debentures to be
delivered upon such distribution, and having an aggregate principal amount equal
to the aggregated stated liquidation amount of, with an interest rate identical
to the Coupon Rate of, and accrued and unpaid interest equal to accrued and
unpaid Distributions on such Securities.  Any certificates representing
Securities, except for certificates representing Preferred Securities held by
the Clearing Agency or its nominee (or any successor Clearing Agency or its
nominee), will be deemed to represent beneficial interests in the Debentures
having an aggregate principal amount equal to the aggregated stated liquidation
amount of, with an interest rate identical to the Coupon Rate of, and accrued
and unpaid interest equal to accrued and unpaid Distributions on such Securities
until such certificates are presented to the Debenture Issuer or its agent for
transfer or reissue.  If the Debentures are distributed to Holders of the
Securities, pursuant to the terms of the Indenture, the Debenture Issuer will
use its best efforts to have the Debentures listed on the New York Stock
Exchange or on such other exchange as the Preferred Securities were listed
immediately prior to the distribution of the Debentures.

     (f) Redemption or Distribution Procedures.
         ------------------------------------- 

          (i) Notice of any redemption of, or notice of distribution of
     Debentures in exchange for, the Securities (a "Redemption/Distribution
     Notice") will be given by the Trust by mail to each Holder of Securities to
     be redeemed or exchanged not fewer than 30 nor more than 60 days before the
     date fixed for redemption or exchange thereof which, in the case of a
     redemption, will be the date fixed for redemption of the Debentures.  For
     purposes of the calculation of the date of redemption or exchange and the
     dates on which notices are given pursuant to this Section 4(f)(i), a
     Redemption/Distribution Notice shall be deemed to be given on the day such
     notice is first mailed by first-class mail, postage prepaid, to Holders of
     Securities.  Each Redemption/Distribution Notice shall be addressed to the
     Holders of Securities at the address of each such Holder appearing in the
     books and records of the Trust.  No defect in the Redemption/Distribution
     Notice or in 

                                      57
<PAGE>
 
     the mailing of either thereof with respect to any Holder shall affect the
     validity of the redemption or exchange proceedings with respect to any
     other Holder.

          (ii) In the event that fewer than all the outstanding Securities are
     to be redeemed, the Preferred Securities to be redeemed shall be redeemed
     Pro Rata from each Holder of Preferred Securities, it being understood
     that, in respect of Preferred Securities registered in the name of and held
     of record by the Clearing Agency or its nominee (or any successor Clearing
     Agency or its nominee), the distribution of the proceeds of such redemption
     will be made to each Clearing Agency Participant (or Person on whose behalf
     such nominee holds such securities) in accordance with the procedures
     applied by such agency or nominee.

          (iii) If Securities are to be redeemed and the Trust gives a
     Redemption/Distribution Notice (which notice will be irrevocable), then (A)
     while the Preferred Securities are in global form, with respect to the
     Preferred Securities, by 12:00 noon, New York City time, on the redemption
     date, provided that the Debenture Issuer has paid the Property Trustee a
     sufficient amount of cash in connection with the related redemption or
     maturity of the Debentures, the Property Trustee will deposit irrevocably
     with the Clearing Agency or its nominee (or successor Clearing Agency or
     its nominee) funds sufficient to pay the applicable Redemption Price with
     respect to the Preferred Securities and will give the Clearing Agency
     irrevocable instructions and authority to pay the Redemption Price to the
     Holders of the Preferred Securities, and (B) with respect to Preferred
     Securities issued in definitive form and Common Securities, provided that
     the Debenture Issuer has paid the Property Trustee a sufficient amount of
     cash in connection with the related redemption or maturity of the
     Debentures, the Property Trustee will pay the relevant Redemption Price to
     the Holders of such Securities by check mailed to the address of the
     relevant Holder appearing on the books and records of the Trust on the
     redemption date.  If a Redemption/Distribution Notice shall have been given
     and funds deposited as required, then immediately prior to the close of
     business on the date of such deposit, Distributions will cease to accrue on
     the Securities so called for redemption and all rights of Holders of such
     Securities so called for redemption will cease, except the right of the
     Holders of such Securities to receive the Redemption Price, but without
     interest on such Redemption Price. Neither the Regular Trustees nor the
     Trust shall be required to register or cause to be registered the transfer
     of any Securities that have been so called for redemption.  If any date
     fixed for redemption of Securities is not a Business Day, then payment of
     the Redemption Price payable on such date will be made on the next
     succeeding day that is a Business Day (and without 

                                      58
<PAGE>
 
     any interest or other payment in respect of any such delay) except that, if
     such Business Day falls in the next calendar year, such payment will be
     made on the immediately preceding Business Day, in each case with the same
     force and effect as if made on such date fixed for redemption. If the
     Debenture Issuer fails to repay the Debentures on the date of redemption or
     on maturity or if payment of the Redemption Price in respect of any
     Securities is improperly withheld or refused and not paid either by the
     Property Trustee or by the Sponsor as guarantor pursuant to the relevant
     Securities Guarantee, Distributions on such Securities will continue to
     accrue at the then applicable rate from the original redemption date to the
     actual date of payment, in which case the actual payment date will be
     considered the date fixed for redemption for purposes of calculating the
     Redemption Price.

          (iv) Redemption/Distribution Notices shall be sent by the Regular
     Trustees on behalf of the Trust to (A) in respect of the Preferred
     Securities, the Clearing Agency or its nominee (or any successor Clearing
     Agency or its nominee) if the Global Certificates have been issued or, if
     Definitive Preferred Security Certificates have been issued, to the Holders
     thereof, and (B) in respect of the Common Securities to the Holder thereof.

          (v) Subject to the foregoing and applicable law (including, without
     limitation, United States federal securities laws), the Sponsor or any of
     its subsidiaries may at any time and from time to time purchase outstanding
     Preferred Securities by tender offer, in the open market or by private
     agreement.

5.   Voting Rights - Preferred Securities.
     ------------------------------------ 

     (a) Except as provided under Sections 5(b) and 7 and as otherwise required
by law and the Declaration, the Holders of the Preferred Securities will have no
voting rights.

     (b) Subject to the requirements set forth in this paragraph, the Holders of
a Majority in Liquidation Amount of the Preferred Securities, voting separately
as a class, may direct the time, method and place of conducting any proceeding
for any remedy available to the Property Trustee, or direct the exercise of any
trust or power conferred upon the Property Trustee under the Declaration,
including the right to direct the Property Trustee, as Holder of the Debentures,
to: (i) exercise the remedies available under the Indenture with respect to the
Debentures; (ii) waive any past default and its consequences that is waivable
under the Indenture; or (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable,
or consent to any amendment, modification or termination of the Indenture or the
Debentures, where such consent would be required; provided that where a consent
or action under the Indenture would require the consent or act of the Holders of
greater than a majority in principal amount of Debentures affected thereby (a
"Super Majority"), the Property Trustee may only give such consent or take such
action at the written direction of the Holders of at least the proportion in
liquidation amount of the 

                                      59
<PAGE>
 
Preferred Securities which the relevant Super Majority represents of the
aggregate principal amount of the Debentures outstanding. The Property Trustee
shall not revoke any action previously authorized or approved by a vote of the
Holders of the Preferred Securities. Other than with respect to directing the
time, method and place of conducting a proceeding for any remedy available to
the Property Trustee or the Debenture Trustee as set forth above, the Property
Trustee shall not take any action in accordance with the directions of the
Holders of the Preferred Securities under this paragraph unless the Property
Trustee has obtained an opinion of tax counsel to the effect that for the
purposes of United States federal income tax the Trust will not be classified as
other than a grantor trust on account of such action. If the Property Trustee
fails to enforce its rights with respect to the Debentures held by the Trust to
the fullest extent permitted by law, any Holder of the outstanding Preferred
Securities may, to the extent permitted by applicable law, institute legal
proceedings directly against the Debenture Issuer to enforce the Property
Trustee's rights under the Debentures without first instituting any legal
proceedings against the Property Trustee or any other person or entity.
Notwithstanding the foregoing, if an Event of Default under the Declaration has
occurred and is continuing and such event is attributable to the failure of the
Debenture Issuer to pay interest or principal on the Debentures issued to the
Trust on the date such interest or principal is otherwise payable, then a Holder
of Preferred Securities may institute a proceeding directly against the
Debenture Issuer for enforcement of payment to the Holder of the Preferred
Securities of the principal of or interest on the Debentures on or after the
respective due dates specified in the Debentures, and the amount of the payment
will be based on the Holder's pro rata share of the amount due and owing on all
of the Preferred Securities.

     Any approval or direction of Holders of Preferred Securities may be given
at a separate meeting of Holders of Preferred Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Regular Trustees will cause a notice of any
meeting at which Holders of Preferred Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of Preferred Securities.  Each such notice will include
a statement setting forth (i) the date of such meeting or the date by which such
action is to be taken, (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled to vote or of such
matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consents.

     No vote or consent of the Holders of the Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

     Notwithstanding that Holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities that are owned by the Sponsor or any Affiliate of the Sponsor shall
not be entitled to vote or consent and shall, for purposes of such vote or
consent, be treated as if they were not outstanding.

6.  Voting Rights - Common Securities.
    --------------------------------- 

                                      60
<PAGE>
 
     (a) Except as provided under Sections 6(b) and (c) and as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

     (b) The Holders of the Common Securities are entitled, in accordance with
Article V of the Declaration, to vote to appoint, remove or replace any Trustee
or to increase or decrease the number of Trustees.

     (c) Subject to Section 2.6 of the Declaration and only after any Event of
Default with respect to the Preferred Securities has been cured, waived or
otherwise eliminated and subject to the requirements set forth in this
paragraph, the Holders of a Majority in Liquidation Amount of the Common
Securities, voting separately as a class, may direct the time, method and place
of conducting any proceeding for any remedy available to the Property Trustee,
or direct the exercise of any trust or power conferred upon the Property Trustee
under the Declaration, including the right to direct the Property Trustee, as
Holder of  the Debentures, to: (i) exercise the remedies available under the
Indenture with respect to the Debentures; (ii) waive any past default and its
consequences that is waivable under the Indenture; or (iii) exercise any right
to rescind or annul a declaration that the principal of all the Debentures shall
be due and payable, or consent to any amendment, modification or termination of
the Indenture or the Debentures, where such consent would be required; provided
that, where a consent or action under the Indenture would require the consent or
act of a Super Majority of the Holders of the Debentures affected thereby, the
Property Trustee may only give such consent or take such action at the written
direction of the Holders of at least the proportion in liquidation amount of the
Common Securities which the relevant Super Majority represents of the aggregate
principal amount of the Debentures outstanding. The Property Trustee shall not
revoke any action previously authorized or approved by a vote of the Holders of
the Common Securities.  Other than with respect to directing the time, method
and place of conducting a proceeding for any remedy available to the Property
Trustee or the Debenture Trustee as set forth above, the Property Trustee shall
not take any action in accordance with the directions of the Holders of the
Common Securities under this paragraph unless the Property Trustee has obtained
an opinion of tax counsel to the effect that for the purposes of United States
federal income tax the Trust will not be classified as other than a grantor
trust on account of such action.  If the Property Trustee fails to enforce its
rights with respect to the Debentures held by the Trust, any Holder of Common
Securities may, to the extent permitted by applicable law, institute legal
proceedings directly against the Debenture Issuer to enforce the Property
Trustee's rights under the Debentures without first instituting any legal
proceedings against the Property Trustee or any other person or entity.

     Notwithstanding the foregoing, if an Event of Default under the Declaration
has occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest or principal on the Debentures issued to
the Trust on the date such interest or principal is otherwise payable, then a
Holder of Common Securities may institute a proceeding directly against the
Debenture Issuer for enforcement of payment to the Holder of the Common
Securities of the principal of or interest on the Debentures on or after the
respective due dates specified in the Debentures, and the amount of the payment
will be based on the Holder's pro rata share of the amount due and owing on all
of the Common Securities.

                                      61
<PAGE>
 
     Any approval or direction of Holders of Common Securities may be given at a
separate meeting of Holders of Common Securities convened for such purpose, at a
meeting of all of the Holders of Securities in the Trust or pursuant to written
consent. The Regular Trustees will cause a notice of any meeting at which
Holders of Common Securities are entitled to vote, or of any matter upon which
action by written consent of such Holders is to be taken, to be mailed to each
Holder of Common Securities.  Each such notice will include a statement setting
forth: (i) the date of such meeting or the date by which such action is to be
taken; (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote or of such matter upon which
written consent is sought; and (iii) instructions for the delivery of proxies or
consents.

     No vote or consent of the Holders of the Common Securities will be required
for the Trust to redeem and cancel Common Securities or to distribute the
Debentures in accordance with the Declaration and the terms of the Securities.

7.  Amendments to Declaration and Indenture.
    --------------------------------------- 

     (a) In addition to any requirements under Section 12.1 of the Declaration,
if any proposed amendment to the Declaration provides for, or the Regular
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers, preferences or special rights of the Securities, whether by way of
amendment to the Declaration or otherwise, or (ii) the dissolution, winding-up
or termination of the Trust, other than as described in Section 8.1 of the
Declaration, then the Holders of outstanding Securities voting together as a
single class will be entitled to vote on such amendment or proposal (but not on
any other amendment or proposal) and such amendment or proposal shall not be
effective except with the approval of the Holders of at least a Majority in
Liquidation Amount of the Securities affected thereby, voting together as a
single class; provided, however, if any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or only
the Common Securities, then only the affected class will be entitled to vote on
such amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in Liquidation Amount of such class of
Securities.

     (b) In the event the consent of the Property Trustee as the holder of the
Debentures is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the Property
Trustee shall request the written direction of the Holders of the Securities
with respect to such amendment, modification or termination and shall vote with
respect to such amendment, modification or termination as directed by a Majority
in Liquidation Amount of the Securities voting together as a single class;
provided, however, that where a consent under the Indenture would require the
consent of a Super Majority of the Holders of the Debentures, the Property
Trustee may only give such consent at the direction of the Holders of at least
the proportion in liquidation amount of the Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding; provided, further, that the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Securities under
this Section 7(b) unless the Property Trustee has obtained an opinion of tax
counsel to the

                                      62
<PAGE>
 
effect that for the purposes of United States federal income tax the Trust will
not be classified as other than a grantor trust on account of such action.

8.  Pro Rata.
    -------- 

     A reference in these terms of the Securities to any payment, distribution
or treatment as being "Pro Rata" shall mean pro rata to each Holder of
Securities according to the aggregate liquidation amount of the Securities held
by the relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Preferred Securities pro rata according to the aggregate liquidation amount of
Preferred Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Preferred Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Preferred Securities, to
each Holder of Common Securities pro rata according to the aggregate liquidation
amount of Common Securities held by the relevant Holder relative to the
aggregate liquidation amount of all Common Securities outstanding.  When the
Property Trustee is making payments on the Securities, it is entitled to assume
that no Event of Default has occurred and is continuing unless the Event of
Default is actually known to a Responsible Officer of the Property Trustee.

9.  Ranking.
    ------- 

     The Preferred Securities rank pari passu and payment thereon shall be made
Pro Rata with the Common Securities except that, where an Event of Default
occurs and is continuing under the Indenture in respect of the Debentures held
by the Property Trustee, the rights of Holders of the Common Securities to
payment in respect of Distributions and payments upon liquidation, redemption
and otherwise are subordinated to the rights to payment of the Holders of the
Preferred Securities.

10.  Listing.
     ------- 

     The Regular Trustees shall use their best efforts to cause the Preferred
Securities to be listed for quotation on The New York Stock Exchange, Inc.

11.  Acceptance of Securities Guarantee and Indenture.
     ------------------------------------------------ 

     Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee, including the subordination provisions therein and to the provisions
of the Indenture and the Debentures.

12.  No Preemptive Rights.

                                      63

Securities Guarantee and the Indenture to a Holder without charge on written
request to the Sponsor at its principal place of business.

                                  EXHIBIT A-1

                    FORM OF PREFERRED SECURITY CERTIFICATE

     This Preferred Security Certificate is a Global Certificate within the
meaning of the Declaration hereinafter referred to and is registered in the name
of The Depository Trust Company (the "Depository") or a nominee of the
Depository.  This Preferred Security Certificate is exchangeable for Preferred
Securities registered in the name of a person other than the Depository or its
nominee only in the limited circumstances described in the Declaration and no
transfer of this Preferred Security Certificate (other than a transfer of this
Preferred Security Certificate 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 limited circumstances.

     Unless this Preferred Security Certificate is presented by an authorized
representative of the Depository to the Trust or its agent for registration of
transfer, exchange or payment, and any Preferred Security Certificate issued is

     Distributions payable on each Preferred Security will be fixed at a rate
per annum of ____% (the "Coupon Rate") of the stated liquidation amount of $25
per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee.  Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law).  The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated.  A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has funds available therefor.
The amount of Distributions payable for any period will be computed for any full
quarterly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any period shorter than a full quarterly Distribution period for
which Distributions are computed, Distributions will be computed on the basis of
the actual number of days elapsed per 90-day quarter.

     Except as otherwise described below, distributions on the Preferred
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on March 31, June 30, September 30 and
December 31 of each year, commencing on                 , 1999, which payment
dates shall correspond to the interest payment dates on the Debentures.  The
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period from time to time on the Debentures for
a period not exceeding 20 consecutive quarters or extending beyond the Maturity
Date of the Debentures (each, an "Extension Period") and, as a consequence of
any such deferral, Distributions will also be deferred.  Despite such deferral,
quarterly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the Coupon Rate compounded quarterly
during any such Extension Period.  Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters and may not extend
beyond the Maturity Date of the Debentures.  Payments of accrued Distributions
will be payable to Holders as they appear on the books and records of the Trust
on the record date after the end of the Extension Period.  Upon the termination
of any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

     The Preferred Securities shall be redeemable as provided in the
Declaration.

                         [FORM OF REVERSE OF SECURITY]

     Distributions payable on each Common Security will be fixed at a rate per
annum of ___% (the "Coupon Rate") of the stated liquidation amount of $25 per
Common Security, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee.  Distributions in arrears for more than one
quarter will bear interest thereon compounded quarterly at the Coupon Rate (to
the extent permitted by applicable law).  The term "Distributions" as used
herein includes such cash distributions and any such interest payable unless
otherwise stated.  A Distribution is payable only to the extent that payments
are made in respect of the Debentures held by the Property Trustee and to the
extent the Property Trustee has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

     Except as otherwise described below, distributions on the Common Securities
will be cumulative, will accrue from the date of original issuance and will be
payable quarterly in arrears, on March 31, June 30,  September 30 and December
31 of each year, commencing on _________________, 1999,  to Holders of record on
a date to be selected by the Regular Trustees, which dates shall be at least one
Business Day  but less than 60 Business Days before the relevant payment dates,
which payment dates shall correspond to the interest payment dates on the
Debentures. The Debentures Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period") and, as a consequence of such deferral, Distributions will
also be deferred.  Despite such deferral, quarterly Distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at
the Coupon Rate compounded quarterly during any such Extension Period.  Prior to
the termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters.  Payments of accrued Distributions will be payable to Holders as they
appear on the books and records of the Trust on the first record date after the
end of the Extension Period.  Upon the termination of any Extension Period and
the Payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

     The Common Securities shall be redeemable as provided in the Declaration.

Motorola Capital Trust I, a Delaware statutory business trust (the "Issuer").

     WHEREAS, pursuant to the Declaration (as defined herein), the Issuer is
issuing up to 20,000,000 preferred securities, having an aggregate liquidation
amount of $500,000,000, designated the ____% Trust Originated Preferred

in any Successor Preferred Guarantee Trustee, and such vesting and cessation of
title shall be effective whether or not conveyancing documents have been
executed and delivered pursuant to the appointment of such Successor Preferred

specifically set forth in this Preferred Securities Guarantee, and no implied
covenants shall be read into this Preferred Securities Guarantee against the
Preferred Guarantee Trustee.  In case a Guarantee Event of Default has occurred

known to a Responsible Officer of the Preferred Guarantee Trustee, the Preferred
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Preferred Securities Guarantee, and use the same degree of care and skill
in its exercise thereof, as a prudent individual would exercise or use under the
circumstances in the conduct of his or her own affairs.
 
     (d) No provision of this Preferred Securities Guarantee shall be construed
to relieve the Preferred Guarantee Trustee from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except
that:

          (i) prior to the occurrence of any Guarantee Event of Default and
              after the curing or waiving of all such Guarantee Events of
              Default that may have occurred:
 
              (A) the duties and obligations of the Preferred Guarantee Trustee
                  shall be determined solely by the express provisions of this
                  Preferred Securities Guarantee, and the Preferred Guarantee
                  Trustee shall not be liable except for the performance of such
                  duties and obligations as are specifically set forth in this
                  Preferred Securities Guarantee, and no implied covenants or

<PAGE>
 
                  obligations shall be read into this Preferred Securities
                  Guarantee against the Preferred Guarantee Trustee; and
 
              (B) in the absence of bad faith on the part of the Preferred
                  Guarantee Trustee, the Preferred Guarantee Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Preferred Guarantee
                  Trustee and conforming to the requirements of this Preferred
                  Securities Guarantee; but in the case of any such certificates
                  or opinions that by any provision hereof are specifically
                  required to be furnished to the Preferred Guarantee Trustee,
                  the Preferred Guarantee Trustee shall be under a duty to
                  examine the same to determine whether or not they conform to
                  the requirements of this Preferred Securities Guarantee;

          (ii)  the Preferred Guarantee Trustee shall not be liable for any 
                error of judgment made in good faith by a Responsible Officer of
                the Preferred Guarantee Trustee, unless it shall be proved that
                the Preferred Guarantee Trustee was negligent in ascertaining
                the pertinent facts upon which such judgment was made;
 
          (iii) the Preferred Guarantee Trustee shall not be liable with respect
                to any action taken or omitted to be taken by it in good faith
                in accordance with the direction of the Holders of not less than
                a Majority in Liquidation Amount of the Preferred Securities
                relating to the time, method and place of conducting any
                proceeding for any remedy available to the Preferred Guarantee
                Trustee, or exercising any trust or power conferred upon the
                Preferred Guarantee Trustee under this Preferred Securities
                Guarantee; and
 
          (iv)  no provision of this Preferred Securities Guarantee shall 
                require the Preferred Guarantee Trustee to expend or risk its
                own funds or otherwise incur personal financial liability in the
                performance of any of its duties or in the exercise of any of
                its rights or powers, if there are reasonable grounds for
                believing that the repayment of such funds or liability is not
                reasonably assured to the Preferred Guarantee Trustee under the
                terms of this Preferred Securities Guarantee or indemnity,
                reasonably satisfactory to the Preferred Guarantee Trustee,
                against such risk or liability is not reasonably assured to it.

                 inquire as to the authority of the Preferred Guarantee Trustee
                 to so act or as to its compliance with any of the terms and
                 provisions of this Preferred Securities Guarantee, both of
                 which shall be conclusively evidenced by the Preferred
                 Guarantee Trustee's or its agent's taking such action.
 
          (x)    Whenever in the administration of this Preferred Securities
                 Guarantee the Preferred Guarantee Trustee shall deem it
                 desirable to receive instructions with respect to enforcing any
                 remedy or right or taking any other action hereunder, the
                 Preferred Guarantee Trustee (i) may request instructions from
                 the Holders of a Majority in Liquidation Amount of the
                 Preferred Securities, (ii) may refrain from enforcing such
                 remedy or right or taking such other action until such
                 instructions are received and (iii) shall be protected 
                 in conclusively relying on or acting in accordance with such
                 instructions.

          (xi)   The Preferred Guarantee Trustee shall not be required to give 
                 any bond or surety in respect of the performance of its powers
                 and duties hereunder.

          (xii)  The permissive rights of the Preferred Guarantee Trustee to do
                 things enumerated in this Indenture shall not be construed as 
                 a duty.

     (b) No provision of this Preferred Securities Guarantee shall be deemed to
impose any duty or obligation on the Preferred Guarantee Trustee to perform any
act or acts or exercise any 

                                       10
<PAGE>
 
right, power, duty or obligation conferred or imposed on it in any jurisdiction
in which it shall be illegal, or in which the Preferred Guarantee Trustee shall
be unqualified or incompetent in accordance with applicable law, to perform any
such act or acts or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Preferred Guarantee Trustee shall
be construed to be a duty.
 
     SECTION 3.3   Not Responsible for Recitals or Issuance of Guarantee.  The
recitals contained in this Preferred Securities Guarantee shall be taken as the
statements of the Guarantor, and the Preferred Guarantee Trustee does not assume
any responsibility for their correctness.  The Preferred Guarantee Trustee makes
no representation as to the validity or sufficiency of this Preferred Securities
Guarantee.

               or to the requirements of the supervising or examining authority
               referred to above, then, for the purposes of this Section
               4.1(a)(ii), the combined capital and surplus of such corporation
               or trust company shall be deemed to be its combined capital and
               surplus as set forth in its most recent report of condition so
               published.
 
     (b) If at any time the Preferred Guarantee Trustee shall cease to be

Indenture Act, the Preferred Guarantee Trustee 

                                       11
<PAGE>
 
and Guarantor shall in all respects comply with the provisions of Section 310(b)
of the Trust Indenture Act.
 
     (d) Any corporation into which the Preferred Guarantee 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 Preferred
Guarantee Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Preferred Guarantee
Trustee, shall be a Successor Preferred Guarantee 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.
 
     SECTION 4.2   Appointment, Removal and Resignation of Preferred Guarantee
Trustee.

     (a) Subject to Section 4.2(b), the Preferred Guarantee Trustee (or
Successor Preferred Guarantee Trustee, as the case may be) may be appointed or
removed without cause at any time by the Guarantor.
 
     (b) The Preferred Guarantee Trustee (or Successor Preferred Guarantee
Trustee, as the case may be) shall not be removed in accordance with Section
4.2(a) until a Successor Preferred Guarantee Trustee has been appointed and has
accepted such appointment by written instrument executed by such Successor
Preferred Guarantee Trustee and delivered to the Guarantor.
 
     (c) The Preferred Guarantee Trustee (or Successor Preferred Guarantee
Trustee, as the case may be) appointed to office shall hold office until a
Successor Preferred Guarantee Trustee shall have been appointed or until its
removal or resignation.  The Preferred Guarantee Trustee (or Successor Preferred
Guarantee Trustee, as the case may be) may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the

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

     (e) No Preferred Guarantee Trustee shall be liable for the acts or
omissions to act of any Successor Preferred Guarantee Trustee.

                                       12

     (f) Upon termination of this Preferred Securities Guarantee or removal or
resignation of the Preferred Guarantee Trustee (or Successor Preferred Guarantee
Trustee, as the case may be) pursuant to this Section 4.2, the Guarantor shall

                                   ARTICLE V
                                   GUARANTEE

     SECTION 5.1   Guarantee.  The Guarantor irrevocably and unconditionally
agrees to pay in full the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, to the Holders of record as of
the date upon which such Guarantee Payments are due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer to pay such amounts to the Holders.
 
     SECTION 5.2   Waiver of Notice and Demand. The Guarantor hereby waives
notice of acceptance of this Preferred Securities Guarantee and of any liability
to which it applies or may apply, presentment, demand for payment, any right to
require a proceeding first against the Issuer or any other Person before
proceeding against the Guarantor, protest, notice of nonpayment, notice of
dishonor, notice of redemption and all other notices and demands.
Notwithstanding anything to the contrary herein, the Guarantor retains all of
its rights to (i) extend the interest payment period on the Debentures and the
Guarantor shall not be obligated hereunder to make any Guarantee Payments during
any Extended Interest Payment Period (as defined in the Indenture) with respect
to the Distributions (as defined in the Declaration) on the Preferred Securities
and (ii) redeem or change the maturity date of the Debentures, in each case to
the extent permitted by the Indenture.

     SECTION 5.3   Obligations Not Affected.  The obligations, covenants,
agreements and duties of the Guarantor under this Preferred Securities Guarantee
shall be absolute and unconditional and shall remain in full force and effect
until the entire liquidation amount of all outstanding Preferred Securities
shall have been paid and such obligation shall in no way be affected or impaired
by reason of the happening from time to time of any event, including without
limitation, the following, whether or not with notice to, or the consent of, the
Guarantor:

     (a) The release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;
 
     (b) The extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time 

                                       13
<PAGE>
 
for payment of Distributions, Redemption Price, Liquidation Distribution or
other sum payable that results from the extension of any interest payment period
on the Debentures or any change to the maturity date of the Debentures permitted
by the Indenture);
 
     (c) Any failure, omission, delay or lack of diligence on the part of the
Property Trustee or the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Property Trustee or the Holders
pursuant to the terms of the Preferred Securities, or any action on the part of
the Issuer granting indulgence or extension of any kind;
 
     (d) The voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;
 
     (e) Any invalidity of, or defect or deficiency in, the Preferred
Securities;
 
     (f) The settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or
 
     (g) Any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

There shall be no obligation of the Preferred Guarantee Trustee or the Holders
to give notice to, or obtain consent of, the Guarantor or any other Person with
respect to the happening of any of the foregoing.  No set-off, counterclaim,
reduction or diminution of any obligation, or any defense of any kind or nature
that the Guarantor has or may have against any Holder shall be available
hereunder to the Guarantor against such Holder to reduce the payments to it
under this Preferred Securities Guarantee.
 
     SECTION 5.4   Rights of Holders.
 
     (a) The Holders of a Majority in Liquidation Amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Preferred Guarantee Trustee in
respect of this Preferred Securities Guarantee or to direct the exercise of any
trust or power conferred upon the Preferred Guarantee Trustee under this
Preferred Securities Guarantee.
 
     (b) If the Preferred Guarantee Trustee fails to enforce this Preferred
Securities Guarantee, then any Holder of Preferred Securities may institute a
legal proceeding directly against the Guarantor to enforce the Preferred
Guarantee Trustee's rights under this Preferred Securities Guarantee without
first instituting a legal proceeding against the Issuer, the Preferred Guarantee

                                       14
<PAGE>
 
Trustee or any other Person or entity.  Notwithstanding the foregoing, if the
Guarantor has failed to make a Guarantee Payment, a Holder of Preferred
Securities may directly institute a proceeding against the Guarantor for
enforcement of the Preferred Securities Guarantee for such payment to the Holder
of the Preferred Securities of the principal of or interest on the Debentures on
or after the respective due dates specified in the Debentures, and the amount of
the payment will be based on the Holder's pro rata share of the amount due and
owing on all of the Preferred Securities.  The Guarantor hereby waives any right
or remedy to require that any action on this Preferred Securities Guarantee be
brought first against the Issuer or any other Person or entity before proceeding
directly against the Guarantor.
 
     SECTION 5.5   Guarantee of Payment.  This Preferred Securities Guarantee
creates a guarantee of payment and not of collection.
 
     SECTION 5.6   Subrogation.  The Guarantor shall be subrogated to all (if
any) rights of the Holders of Preferred Securities against the Issuer in respect
of any amounts paid to such Holders by the Guarantor under this Preferred
Securities Guarantee; provided, however, that the Guarantor shall not (except to
the extent required by mandatory provisions of law) be entitled to enforce or
exercise any right that it may acquire by way of subrogation or any indemnity,
reimbursement or other agreement, in all cases as a result of payment under this
Preferred Securities Guarantee, if, at the time of any such payment, any amounts
are due and unpaid under this Preferred Securities Guarantee.  If any amount
shall be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Preferred Guarantee Trustee for the benefit of the Holders.
 
     SECTION 5.7   Independent Obligations.  The Guarantor acknowledges that its
obligations hereunder are independent of the obligations of the Issuer with
respect to the Preferred Securities, and that the Guarantor shall be liable as
principal and as debtor hereunder to make Guarantee Payments pursuant to the
terms of this Preferred Securities Guarantee notwithstanding the occurrence of
any event referred to in subsections (a) through (g), inclusive, of Section 5.3
hereof.

     SECTION 5.8   Waiver Under Indenture and Declaration.  Any waiver by the
Holders of any right under the Indenture or the Declaration shall constitute a
waiver of their rights hereunder to the full extent of such waiver.
 
                                   ARTICLE VI
                   LIMITATION OF TRANSACTIONS; SUBORDINATION

     SECTION 6.1   Limitation of Transactions.  So long as any Preferred
Securities remain outstanding, if there shall have occurred a Guarantee Event of
Default or an event of default under the Declaration, then, prior to the payment
of all accrued interest on outstanding Debentures, the Guarantor may not (a)
declare or pay dividends on, make a distribution with respect to, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of its
capital stock, (b) make any payment of interest, principal or premium, if any,
on, or repay, repurchase or redeem, any debt 

                                       15
<PAGE>
 
securities issued by the Guarantor that rank equal with or junior to the
Debentures or (c) make guarantee payments with respect to the foregoing (other
than as set forth in this Preferred Securities Guarantee); provided, however,
that the restriction in clause (a) does not apply to (i) purchases or
acquisitions of the Guarantor's capital stock in connection with the
satisfaction of its obligations under any employee benefit plans, stock option
plans, employee stock purchase plans or direct reinvestment plans as may be in
effect from time to time or the satisfaction of its obligations pursuant to any
contract or security outstanding on the date of such event requiring the
Guarantor to purchase its capital stock (other than a contractual obligation
ranking equal with or junior to the Debentures), (ii) reclassifications of the
Guarantor's capital stock or the exchange or conversion of one class or series
of the Guarantor's capital stock, provided that such reclassification, exchange
or conversion does not result in a change in the priority vis-a-vis the
Preferred Securities of any class or series of capital stock that is being so
reclassified or that is the subject of such exchange or conversion, (iii)
purchases of fractional interests in shares of the Guarantor's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security bring converted or exchanged, (iv) stock dividends paid by the
Guarantor where the dividend stock is the same stock as that on which the
dividend is being paid or (v) redemptions or purchases of any rights pursuant to
purchase rights contained in any rights agreement as shall be in effect from
time to time, which purchase rights are substantially similar to those contained
in the Guarantor's current rights agreement.
 
     SECTION 6.2   Ranking.  This Preferred Securities Guarantee will constitute
an unsecured obligation of the Guarantor and will rank (i) subordinate and
junior in right of payment to all other liabilities of the Guarantor, including
all series of the Guarantor's outstanding LYONS/TM/, except those liabilities of
the Guarantor made equal or subordinate by their terms, (ii) equal with the most
senior preferred or preference stock now or hereafter issued by the Guarantor
and with any guarantee now or hereafter entered into by the Guarantor in respect
of any preferred or preference stock of any Affiliate of the Guarantor, (iii)
senior to the Guarantor's common stock and (iv) effectively subordinated to the
liabilities and obligations of the Guarantor's Subsidiaries to the same extent
as the Debentures as described in the Indenture.  If an Event of Default has
occurred and is continuing under the Declaration, the rights of the holders of
the Common Securities to receive any payments shall be subordinated to the
rights of the Holders of Preferred Securities to receive Guarantee Payments
hereunder.

                                  ARTICLE VII
                                  TERMINATION

     SECTION 7.1   Termination.  This Preferred Securities Guarantee shall
terminate upon (i) full payment of the Redemption Price of all Preferred
Securities, (ii) upon the distribution of the Debentures to the Holders of all
of the Preferred Securities or (iii) upon full payment of the amounts payable in
accordance with the Declaration upon liquidation of the Issuer.  Notwithstanding
the foregoing, this Preferred Securities Guarantee will continue to be effective
or will be reinstated, as the case may be, if at any time any Holder of
Preferred Securities must restore payment of any sums paid under the Preferred
Securities or under this Preferred Securities Guarantee.

     SECTION 8.1   Exculpation.

     (a) No Indemnified Person shall be liable, responsible or accountable in
damages or otherwise to the Guarantor or any Covered Person for any loss, damage
or claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith in accordance with this Preferred Securities
Guarantee and in a manner that such Indemnified Person reasonably believed to be
within the scope of the authority conferred on such Indemnified Person by this
Preferred Securities Guarantee or by law, except that an Indemnified Person
shall be liable for any such loss, damage or claim incurred by reason of such
Indemnified Person's negligence or willful misconduct with respect to such acts
or omissions.
 
     (b) An Indemnified Person shall be fully protected in relying in good faith
upon the records of the Guarantor and upon such information, opinions, reports
or statements presented to the Guarantor by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Guarantor, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Preferred Securities might properly be paid.
 
     SECTION 8.2   Indemnification.  The Guarantor agrees to indemnify each
Indemnified Person for, and to hold each Indemnified Person harmless against,
any loss, liability or expense incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of this
Preferred Securities Guarantee.

     Distributions payable on each Preferred Security will be fixed at a rate
per annum of ____% (the "Coupon Rate") of the stated liquidation amount of $25
per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee.  Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law).  The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated.  A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has funds available therefor.
The amount of Distributions payable for any period will be computed for any full
quarterly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any period shorter than a full quarterly Distribution period for
which Distributions are computed, Distributions will be computed on the basis of
the actual number of days elapsed per 90-day quarter.

     Except as otherwise described below, distributions on the Preferred
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on March 31, June 30, September 30 and
December 31 of each year, commencing on                 , 1999, which payment
dates shall correspond to the interest payment dates on the Debentures.  The
Debenture Issuer has the right under the Indenture to defer payments of interest
by extending the interest payment period from time to time on the Debentures for
a period not exceeding 20 consecutive quarters or extending beyond the Maturity
Date of the Debentures (each, an "Extension Period") and, as a consequence of
any such deferral, Distributions will also be deferred.  Despite such deferral,
quarterly Distributions will continue to accrue with interest thereon (to the
extent permitted by applicable law) at the Coupon Rate compounded quarterly
during any such Extension Period.  Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters and may not extend
beyond the Maturity Date of the Debentures.  Payments of accrued Distributions
will be payable to Holders as they appear on the books and records of the Trust
on the record date after the end of the Extension Period.  Upon the termination
of any Extension Period and the payment of all amounts then due, the Debenture
Issuer may commence a new Extension Period, subject to the above requirements.

     The Preferred Securities shall be redeemable as provided in the
Declaration.

     This Debenture is one of a duly authorized series of Debentures (herein
sometimes referred to as the "Debentures") of Motorola, Inc., a Delaware
corporation (the "Company," which term includes any successor corporation under
the Indenture hereinafter referred to), specified in and all issued or to be
issued in one or more series under and pursuant to an Indenture dated as of
February ____, 1999 (as originally executed or as it may from time to time be
supplemented or amended by one or more supplemental indentures, including the
First Supplemental Indenture dated as of February ____, 1999, the "Indenture"),
duly executed and delivered between the Company and Harris Trust and Savings
Bank, as Trustee (in such capacity, the "Trustee"), to which a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the Holders of the Debentures, and to all of
which provisions the Holder of this Debenture by acceptance hereof, assents and
agrees.  By the terms of the Indenture, the Debentures are issuable in series
that may vary as to amount, date of maturity, rate of interest and in other
respects as provided in the Indenture.  This series of Debentures is limited in
aggregate principal amount as specified in said Indenture.  Defined terms used
but not otherwise defined in this Debenture have the meanings set forth in the
Indenture.

     This Debenture is in Global form within the meaning of the Indenture
hereinafter referred to and is registered in the name of a Depository or a
nominee of a Depository. Unless and until it is exchanged in whole or in part
for securities in certificated form in the limited circumstances described in
the indenture, this security may not be transferred except as a whole by the
depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository or by the Depository or any
such nominee to a successor Depository or a nominee of such successor
Depository.

     Unless this Debenture is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the issuer or its
agent for registration of transfer, exchange or payment, and any Debenture
issued is registered in the name of Cede & Co. or such other name as requested
by an authorized representative of DTC (and any payment hereon is made to Cede &
Co. or to such other entity as is requested by an authorized representative of
DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL since the registered owner hereof, Cede & Co., has an
interest herein.

or such date that is no later than the earlier of: (i) __________________, 2048
or (ii) the Interest Deduction Date, if the Company elects to shorten or extend

herein) in arrears on March 31, June 30, September 30 and December 31 of each
year commencing         1999, at the rate of ________% per annum until the 
principal hereof shall have become due and payable, and on any overdue principal
and (without duplication and to the extent that payment of such interest is

same rate per annum compounded quarterly. The amount of interest payable on any
Interest Payment Date shall be computed on the basis of a 360-day year of twelve
30-day months, and for any period shorter than a full quarter on the basis of
the actual number of days elapsed in such 90-day quarter. The principal of and
the interest on this Debenture shall become due and payable, in the manner, with

provisions, (b) authorizes and directs the Trustee on his or her behalf to take

acceptance hereof, hereby waives all notice of the acceptance of the
subordination provisions contained herein and in the Indenture by each holder of

by each such holder upon said provisions.

of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the time and place and at the rate and in the money herein
prescribed.  All terms used in this Debenture that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

     The provisions of this Debenture are continued on the reverse side hereof
and such continued provisions shall for all purposes have the same effect as
though fully set forth at this place.

                             OF GENERAL APPLICATION

          (2) all other terms used herein which are defined in the TIA, or by

     executed, except as provided in Section 9.5, have the meanings assigned to

     computation;

          (4) the words "Article" and "Section" refer to an Article and Section,
     respectively, of this Indenture; and

          (5) the words "herein," "hereof" and "hereunder" and other words of
     similar import refer to this Indenture as a whole and not to any particular
     Article, Section or other subdivision.

     Article.

Section 1.4.

     "Affiliate" of any specified Person means any other Person directly or

any such lease for any such period shall be the aggregate amount of the rent
payable by the lessee with respect to such period after excluding amounts
required to be paid on account of maintenance and repairs, insurance, taxes,
assessments, water rates and similar charges. In the case of any lease which is

required to be paid under such lease subsequent to the first date upon which it
may be so terminated.

     "Authenticating Agent" means any Person authorized by the Trustee pursuant
to Section 6.14 to act on behalf of the Trustee to authenticate Securities of

foregoing requirements and in each case on any Business Day.

     "Bearer Security" means any Security established pursuant to Section 2.1
which is payable to bearer including, without limitation, unless the context
otherwise indicates, a Security in global bearer form.

certification, and delivered to the Trustee.  Where any provision of this
Indenture refers to action to be taken pursuant to a Board Resolution (including
the establishment of any series of the Securities and the forms and terms
thereof), such action may be taken by any committee of the Board or the Company
or any officer or employee of the Company authorized to take such action by a
Board Resolution.

     "Business Day," when used with respect to any Place of Payment, means each
Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which

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 in the amount and with the
serial numbers therein described; or such facts may be proved by the certificate
or affidavit of the Person holding such Bearer Securities, if such certificate
or affidavit is deemed by the Trustee to be satisfactory.  The Trustee and the
Company may assume that such ownership of any Bearer Security continues until
(1) another certificate or affidavit bearing a later date issued in respect of
the same Bearer Security is produced, (2) such Bearer Security is produced to
the Trustee by some other person, (3) such Bearer Security is surrendered in
exchange for a Registered Security or (4) such Bearer Security is no longer
Outstanding.  The fact and date of execution of any such instrument or writing,
the authority of the Person executing the same and the principal amount and
serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of holding the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

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

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

                                      -14-
<PAGE>
 
other Act, but the Company shall have no obligation to do so. Notwithstanding
TIA Section 316(c), such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not earlier than the
date 30 days prior to the first solicitation of Holders generally in connection
therewith and not later than the date such solicitation is completed. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of record at the close of business on such record date shall be
deemed to be Holders for the purposes of determining whether Holders of the
requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than eleven months after the record date.

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

     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:  Indenture
     Trust Division, or

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

     furnished in writing to the Trustee by the Company.

     SECTION 1.6  Notice to Holders; Waiver.  Where this Indenture provides for
notice of any event to Holders of Registered Securities by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, if any, and not earlier than
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be 

                                      -15-
<PAGE>
 
conclusively deemed to have been received by such Holder, whether or not such
Holder actually receives such notice.

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

     Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 3.1, where this Indenture provides
for notice to Holders of Bearer Securities of any event, such notice shall be
sufficiently given if published in an Authorized Newspaper in the City of New
York and, if the Securities of such series are then listed on the International
Stock Exchange of the United Kingdom and the Republic of Ireland and such stock
exchange shall so require, in London, and, if the Securities of such series are
then listed on the Luxembourg Stock Exchange and such stock exchange shall so
require,  in Luxembourg and, if the Securities of such series are than listed on
any other stock exchange outside the United States and such stock exchange shall
so require, in any other required city outside the United States or, if not
practicable, in Europe on a Business Day at least twice, the first such
publication to be not later than the latest date and not earlier than the
earliest date prescribed for the giving of such notice, and in such other city
or cities as may be specified in such Securities on a Business Day, such
publication to be not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice.  Any such notice shall
be deemed to have been given on the date of such publication or, if published
more than once, on the date of the first such publication.

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

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

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

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

Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

     SECTION 1.10  Separability Clause.  In case any provision in this Indenture

Registrar and Authenticating Agent and the Holders, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

shall be governed by and construed in accordance with the law of the State of

     SECTION 1.13  Legal Holidays.  In any case where any Interest Payment Date,
Redemption Date, Repayment Date, Stated Maturity or 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 of 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, Repayment Date, Stated Maturity or Maturity, provided that no
interest shall accrue for the period from and after such Interest Payment Date,
Redemption Date, Repayment Date, Stated Maturity or Maturity, as the case may
be.

     SECTION 1.14  Counterparts.  This Indenture may be executed in any number 
of counterparts, each of which so executed shall be deemed to be an original,
but all such counterparts shall together constitute but one and the same
Indenture.

                                 SECURITY FORMS

     SECTION 2.1  Forms Generally.  The Registered Securities, if any, and the 
Bearer Securities and related coupons, if any, of each series shall be in
substantially the 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 market 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 the form of
Securities of any series or coupons is established by action taken pursuant to a
Board Resolution, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 3.3 for the authentication and delivery of such
Securities or coupons.

     Unless otherwise specified as contemplated by Section 3.1, Bearer
Securities other than Securities in temporary or permanent global form shall
have coupons attached.

     The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved or produced by any combination of these methods on
steel engraved borders or may be produced in any other manner permitted by the
rules of any securities exchange on which the Securities may be listed, 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 certificate of authentication on each Security shall be in
substantially the following form:

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

                              _________________________________ 
                              as Trustee

                              By ______________________________
                                    [AUTHORIZED OFFICER]

     SECTION 2.3  Securities Issuable in Global Form.  If Securities of or 
within a series are issuable in global form, as specified as contemplated by
Section 3.1, then, notwithstanding clause (9) of Section 3.1 and the provisions
of Section 3.2, any such Global Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that 

                                      -18-
<PAGE>
 
it shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased
or decreased to reflect exchanges. Any endorsement of a Global Security 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 3.4. Subject to the provisions of Section 3.3 and, if applicable, 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, delivery or 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(g) 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(g).

     Notwithstanding the provisions of Section 3.7, unless otherwise specified
as contemplated by Section 3.1, payment of principal of  (and premium, if any)
and interest, if any, on any permanent Global Security shall be made to the
Person or Persons specified therein.

     Notwithstanding the provisions of Section 3.9 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a permanent Global Security (i) in the case of a
permanent Global Security in registered form, the Holder of such permanent
Global Security in registered form, or (ii) in the case of a permanent Global
Security in bearer form, Euroclear or CEDEL.

payable, with different rates of interest, if any, or different methods by which
rates of interest may be determined, with different dates on which such interest

shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

     SECTION 3.2  Denominations.  Securities of each series shall be issuable 
in such form and denominations as shall be specified in the form of Security for

$1,000 and any integral multiples thereof and the Bearer Securities of such
series, if any (other than Bearer Securities in global form, which may be in any

     (a) The Securities shall be executed on behalf of the Company by its Chief
Executive Officer, its President, its Treasurer or one of its Vice Presidents,
under its corporate seal reproduced thereon and shall be attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile. Coupons shall bear the
facsimile signature of an authorized officer of the Company.

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

     (b) At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, executed by
the Company, to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Securities, and, except as otherwise
provided in this Article Three,  the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 3.1, 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 set forth in Exhibit A-1
to this Indenture or such other certificate as may be specified 

                                      -23-
<PAGE>
 
with respect to any series of Securities pursuant to Section 3.1, dated no
earlier than 15 days prior to the earlier of the date on which such Bearer
Security is delivered and the date on which any temporary Security first becomes
exchangeable for such Bearer Security in accordance with the terms of such
temporary Security and this Indenture. If any Security shall be represented by a
permanent Global Bearer Security, then, for purposes of this Section 3.3 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 canceled. If all the Securities of any series are not to be
issued at one time and if the Board Resolution or supplemental indenture
establishing such series shall so permit, such Company Order may set forth
procedures acceptable to the Trustee for the issuance of such Securities and
determining the terms of particular Securities of such series, such as interest
rate, maturity date, date of issuance and date from which interest shall accrue.
If the form or terms of the Securities of the series 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) if the form of such Securities and coupons, if any, has been
     established by or pursuant to a Board Resolution as permitted by Section
     2.1, that such form has been established in conformity with the provisions
     of this Indenture;

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

          (C) that such Securities and coupons, if any, when authenticated and
     delivered by the Trustee and issued by the Company in the manner and
     subject to any conditions specified in such Opinion of Counsel, will
     constitute valid and legally binding obligations of the Company,
     enforceable in accordance with their terms, subject to bankruptcy,
     insolvency, fraudulent transfer, reorganization, moratorium and similar
     laws of general applicability relating to or affecting creditors' rights
     and to general equity principles and except further as enforcement thereof
     may be limited by (1) requirements that a claim with respect to any
     Securities denominated other than in Dollars (or a Foreign Currency or
     Currency unit judgment in respect of such claim) be converted into Dollars
     at a rate of exchange prevailing on a date determined pursuant to
     applicable law or (2) governmental authority to limit, delay or prohibit
     the making of payments in Foreign Currencies or Currency units or payments
     outside the United States.

     (c) If the Company shall establish pursuant to Section 3.1 that the
Securities of a series are to be issued in whole or in part in the form of one
or more Global Securities, then the Company 

                                      -24-
<PAGE>
 
shall execute and the Trustee shall, in accordance with this Section 3.3,
Section 3.4, if and to the extent applicable, and the Company Order with respect
to such series, authenticate and deliver one or more Global Securities in
permanent or temporary form that (i) shall represent and shall be denominated in
an aggregate principal amount of the Outstanding Securities of such series to be
represented by one or more Global Securities, (ii) shall be registered in the
name of the Depositary for such Global Security or Securities or the nominee of
such Depositary and (iii) shall be delivered by the Trustee to such Depositary
or pursuant to such Depositary's instructions.

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

     (e) Notwithstanding the provisions of Section 3.1 and this Section 3.3, 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 paragraph 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.

     (f) Each Registered Security shall be dated the date of its authentication.
Each Bearer Security shall be dated the date contemplated by Section 3.1.

     (g) No Security or attached coupon shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless executed and
issued by the Company and there appears on such Security a certificate of
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder and is entitled to the benefits of this
Indenture.  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 canceled. 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 3.10, 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.

     (h) Each Depositary designated pursuant to Section 3.1 for a Global
Security must, at the time of its designation and at all times while it serves
as Depositary, be a clearing agency registered under the Exchange Act and any
other applicable statute or regulation.

     (i) The Securities may contain such notations, legends or endorsements
required by law, stock exchange rule or usage.

     SECTION 3.4  Temporary Securities.

     (a) Pending the preparation of definitive Securities of any series, the
Company may execute, and upon receipt of a Company Order the Trustee shall
authenticate and deliver, temporary Securities which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities.  In the case of Securities of any series, such temporary Securities
may be in global form.

     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with Section 3.4(b) or as otherwise provided in or
pursuant to a Board Resolution), or as otherwise provided in or pursuant to a
Board Resolution, if temporary Securities of any series are issued, the Company
will cause definitive Securities of that series to be prepared without
unreasonable delay.  After the preparation of definitive Securities of such
series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Company in a Place of Payment for
that series, without charge to the Holder.  Upon surrender for cancellation of
any one or more temporary Securities of any series (accompanied by any non-
matured coupons appertaining thereto), the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations; provided,
however, that unless otherwise contemplated or specified with respect to any
series of Securities pursuant to Section 3.1, no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and provided
further that a Bearer Security shall be delivered in exchange for a Bearer
Security only in compliance with the applicable conditions set forth in Sections
3.3, 3.4 and 3.5.  Until so exchanged, the temporary Securities of any series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

     (b) Unless otherwise provided in or pursuant to a Board Resolution, this
Section 3.4(b) shall govern the exchange of temporary Securities issued in
global form.  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, for the benefit of Euroclear and
CEDEL, for credit to the respective accounts of the beneficial owners of such
Securities (or to such other accounts as they may direct).

     Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Company.  On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Depositary to the Trustee, as the 

                                      -26-
<PAGE>
 
Company's agent for such purpose, to be exchanged, in whole or from time to time
in part, for definitive Securities without charge, and upon receipt of a Company
Order, the Trustee shall authenticate and deliver, in exchange for each portion
of such temporary Global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such temporary Global Security to be exchanged. The
definitive Securities to be delivered in exchange for any such temporary Global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 3.1, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof; provided, however, that, unless
otherwise specified in such temporary Global Security, upon such presentation by
the 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 temporary Global Security held for its account then to be
exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL as to the portion of such temporary Global Security held for its
account then to be exchanged, each in the form, set forth in Exhibit A-2 to this
Indenture or in such other form as may be established pursuant to Section 3.1;
and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary Global Security only in compliance with
the requirements of Section 3.3, 3.4 and Section 3.5, as applicable.

     Unless otherwise specified in such temporary Global Security, the interest
of a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or CEDEL, as the case may be, a certificate in the form set forth
in Exhibit A-1 to this Indenture (or in such other form as may be established
pursuant to Section 3.1), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the officers of
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL.  Definitive
Securities in bearer form to be delivered in exchange for any portion of a
temporary Global Security shall be delivered only outside the United States.

     Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 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 on such
Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee of a
certificate or certificates in the form set forth in Exhibit A-2 to this
Indenture (or in such other forms as may be established pursuant to Section
3.1), for credit without 

                                      -27-
<PAGE>
 
further interest on or after such Interest Payment Date to the respective
accounts of Persons who are the beneficial owners of such temporary Global
Security on such Interest Payment Date and who have each delivered to Euroclear
or CEDEL, as the case may be, a certificate dated no earlier than 15 days prior
to the Interest Payment Date occurring prior to such Exchange Date in the form
set forth as Exhibit A-1 to this Indenture (or in such other forms as may be
established pursuant to Section 3.1). Notwithstanding anything to the contrary
herein contained, the certifications made pursuant to this paragraph shall
satisfy the certification requirements of the preceding two paragraphs of this
Section 3.4(b) and of Section 3.3(b) of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary Global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal (or premium, if any) or interest, if any,
owing with respect to a beneficial interest in a temporary Global Security will
be made unless and until such interest in such temporary Global Security shall
have been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and CEDEL and not paid as herein provided shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

     SECTION 3.5  Registration, Registration of Transfer and Exchange.  The 
Company shall cause to be kept at one of the offices or agencies to be
maintained by the Company in accordance with the provisions of this Section 3.5
and Section 10.2, with respect to the Securities of each series which are
Registered Securities, a register (herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Registered Securities and of
transfers of Registered Securities. Pursuant to Section 3.1, the Company shall
appoint, with respect to Securities of each series which are Registered
Securities, a "Security Registrar" for the purpose of registering such
Securities and transfers and exchanges of such Securities as herein provided.
The Trustee, at its Corporate Trust Office, is initially appointed "Security
Registrar" for such Registered Securities.

     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency of the Company maintained for such purpose,
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 denomination or denominations,
of like tenor and terms and aggregate principal amount, all as requested by the
transferor.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denomination or denominations, of like tenor and terms and aggregate principal
amount, upon surrender of the Registered Securities to be exchanged at such
office or agency.  Unless otherwise specified with respect to any series of
Securities as contemplated by Section 3.1, Bearer Securities may not be issued
in exchange for Registered Securities.

                                      -28-
<PAGE>
 
     At the option of the Holder, Registered Securities or Bearer Securities of
any series may be issued in exchange for Bearer Securities (except as otherwise
specified as contemplated by Section 3.1 with respect to a Bearer Security in
global form) of the same series, of any authorized denominations and of like
tenor and terms and aggregate principal amount, upon surrender of the Bearer
Securities to be exchanged at any such office or agency with all unmatured
coupons and all matured coupons in default thereto appertaining.  If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee 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 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 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 a permitted exchange for a
Registered Security of the same series and like tenor and terms after the close
of business at such office or agency of (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 date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date of 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.

     If at any time the Depositary for the Securities of a series notifies the
Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.3(h), the Company shall
appoint a successor Depositary with respect to the Securities of such series. If
a successor Depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company's election pursuant to Section 3.1(9) shall
no longer be effective with respect to the Securities of such series and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver, Securities of such series in definitive form in an
aggregate principal amount equal to the principal 

                                      -29-
<PAGE>
 
amount of the Global Security or Securities representing such series in exchange
for such Global Security or Securities.

     The Company may at any time and in its sole discretion determine that the
Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities.  In such
event the Company will execute, and the Trustee, upon receipt of a Company Order
for the authentication and delivery of definitive Securities of such series,
will authenticate and deliver, Securities of such series in definitive form and
in an aggregate principal amount equal to the principal amount of the Global
Security or Securities representing such series in exchange for such Global
Security or Securities.

     If specified by the Company pursuant to Section 3.1 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for Securities of such series of like tenor and terms and in definitive form on
such terms as are acceptable to the Company and such Depositary.  Thereupon, the
Company shall execute, and upon receipt of a Company Order, the Trustee shall
authenticate and deliver, without service charge,

          (A) to each Person specified by such Depositary a new Security or
     Securities of the same series, of like tenor and terms and of any
     authorized denominations as requested by such person in aggregate principal
     amount equal to and in exchange for such Person's beneficial interest in
     the Global Security; and

          (B) to such Depositary a new Global Security of like tenor and terms
     and in a denomination equal to the difference, if any, between the
     principal amount of the surrendered Global Security and the aggregate
     principal amount of Securities delivered to Holders thereof.

     In any exchange provided for in any of the preceding three paragraphs, the
Company will execute and upon receipt of a Company Order, the Trustee will
authenticate and deliver Securities (a) in definitive registered form in
authorized denominations, if the Securities of such series are issuable as
Registered Securities, (b) in definitive bearer form in authorized
denominations, with coupons attached, if the Securities of such series are
issuable as Bearer Securities or (c) as either Registered or Bearer Securities,
as shall be specified by the beneficial owner thereof, if the Securities of such
series are issuable in either form; provided, however, that no definitive Bearer
Security shall be delivered in exchange for a temporary Global Security unless
the Company or its agent shall have received from the person entitled to receive
the definitive Bearer Security a certificate substantially in the form set forth
in Exhibit A-1 and, if applicable,  A-2 hereto; and provided further that
delivery of a Bearer Security shall occur only outside the United States; and
provided further that no definitive Bearer Security will be  issued if the
Company has reason to know that any such certificate is false.

                                      -30-
<PAGE>
 
     Upon the exchange of a Global Security for Securities in definitive form,
such Global Security shall be canceled by the Trustee.  Registered Securities
issued in exchange for a Global Security pursuant to this Section shall be
registered in such names and in such authorized denominations as the Depositary
for such Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.  The Trustee shall
deliver such Registered Securities to the persons in whose names such Securities
are so registered.  The Trustee shall deliver Bearer Securities issued in
exchange for a Global Security pursuant to this Section to the persons, and in
such authorized denominations, as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee; provided, however,  that no definitive Bearer
Security shall be delivered in exchange for a temporary Global Security unless
the Company or its agent shall have received from the person entitled to receive
the definitive Bearer Security a certificate substantially in the form set forth
in Exhibit A-1 and, if applicable, A-2 hereto; and provided further  that
delivery of a Bearer Security shall occur only outside the United States; and
provided further that no definitive Bearer Security will be issued if the
Company has reason to know that any such certificate is false.

     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, the Security
Registrar or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar, duly executed by the Holder thereof or 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 transfer, registration of transfer or exchange of Securities, other
than exchanges of Securities expressly provided in this Indenture to be made at
the Company's own expense or without expense or without charge to the Holders.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any particular series to be redeemed for a period of
fifteen days preceding the first publication of the relevant notice of
redemption or, if Registered Securities are outstanding and there is no
publication, the mailing of the relevant notice of redemption of Securities of
such series selected for redemption under Section 11.3 and ending at the close
of business on the day of such mailing, (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 such Registered 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 like tenor
and terms of that series, provided that such Registered Security shall be
simultaneously surrendered for redemption.

                                      -31-
<PAGE>
 
     Notwithstanding anything herein to the contrary, the exchange of Bearer
Securities into Registered Securities shall be subject to applicable laws and
regulations in effect at the time of exchange; neither the Company, the Trustee
nor the Security Registrar shall exchange any Bearer Securities into Registered
Securities if it has received an Opinion of Counsel that as a result of such
exchanges the Company would suffer adverse consequences under the United States
Federal income tax laws and regulations then in effect and the Company has
delivered to the Trustee a Company Order directing the Trustee not to make such
exchanges thereafter unless and until the Trustee receives a subsequent Company
Order to the contrary.  The Company shall deliver copies of such Company Orders
to the Security Registrar.

     SECTION 3.6  Mutilated, Destroyed, Lost and Stolen Securities.  If (i) any
mutilated Security or Security with a mutilated coupon is surrendered to a
Paying Agent outside the United States or, in the case of a Registered Security,
to the Trustee or (ii) the Company and the Trustee receive evidence to their
satisfaction of the loss, destruction or theft of any Security or coupon
together with, in proper cases, such security or indemnity as may be required by
the Company or the Trustee to save each of them or any agent of either of them
harmless, then, in the absence of notice to the Company or the Trustee that such
Security has been acquired by a bona fide purchaser, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor (together
with all 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 any coupons
appertaining to the surrendered Security; provided, that any such Bearer
Security will be delivered only in compliance with Section 3.3, 3.4 and 3.5, as
applicable.

     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, with coupons corresponding to the
coupons, if any, appertaining to such mutilated, destroyed, lost or stolen
Security or to the Security to which such mutilated, destroyed, lost or stolen
coupon appertains, pay such Security or coupon; provided, however, that payment
of principal of (and premium, if any) and interest, if any, 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 and, unless otherwise
specified as contemplated by Section 3.1, any interest on Bearer Securities
shall be payable only upon presentation and surrender of the coupons
appertaining thereto.

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

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

                                      -32-
<PAGE>
 
destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that Series and their
coupons, if any, duly issued hereunder.

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

     SECTION 3.7  Payment of Interest; Interest Rights Preserved; Optional 
Interest Reset.

     (a) Except as otherwise specified with respect to a series of Securities in
accordance with the provision of Section 3.1, interest, if any, on any
Registered Security that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 10.2; provided,
however, that each installment of interest, if any, 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 3.9, to the address of such Person as it appears on the Security
Register or (ii) transfer to an account maintained by the payee inside the
United States.

     Unless otherwise provided as contemplated by Section 3.1 with respect to
the Securities of any series, payment of interest, if any, may be made, in the
case of a Bearer Security, at the Holder's option by (i) check in the Currency
designated for such payment pursuant to the terms of the Bearer Security
presented or mailed to an address outside the United States or (ii) transfer to
an account in such Currency maintained by the payee with a bank located outside
the United States.

     Unless otherwise provided as contemplated by Section 3.01, every permanent
Global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to each of Euroclear and CEDEL with respect to that
portion of such permanent Global Security held for its account by the
Depositary, for the purpose of permitting each of Euroclear and CEDEL to credit
the interest, if any, 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.

     (b) Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 3.1, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment (which shall not be less than 20 days after such notice is
     received by the Trustee), and at the same time the Company shall deposit
     with the Trustee an amount of money in the Currency in which the Securities
     of such series are payable (except as otherwise specified pursuant to
     Section 3.1 for the Securities of such series and except, if applicable, as
     provided in Sections 3.12(b), 3.12(d) and 3.12(e)) equal to the aggregate
     amount proposed to be paid in respect of such Defaulted Interest or shall
     make arrangements satisfactory to the Trustee for such deposit on or prior
     to the date of the proposed payment, such money when deposited to be held
     in trust for the benefit of the Persons entitled to such Defaulted Interest
     as in this clause provided. Thereupon the Trustee shall fix a Special
     Record Date for the payment of such Defaulted Interest which shall be not
     more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the Trustee
     of the notice of the proposed payment. The Trustee shall promptly notify
     the Company of such Special Record Date and, in the name and at the expense
     of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder of Registered Securities of
     such series at his address as it appears in the Security Register not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been mailed as aforesaid, such Defaulted Interest shall be paid to
     the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on such Special Record Date and shall no longer be payable
     pursuant to the following clause (2).  In case a Bearer Security of any
     series is surrendered at the office or agency in a Place of Payment for
     such series in exchange for a Registered Security of such series after the
     close of business at such office or agency on any Special Record Date and
     before the opening of business at such office or agency on the related
     proposed date for payment of Defaulted Interest, such Bearer Security shall
     be surrendered without the coupon relating to such proposed date of payment
     and Defaulted Interest will not be payable on such proposed date of payment
     in respect of the Registered Security issued in exchange for such Bearer
     Security, but will be payable only to the Holder of such coupon when due in
     accordance with the provisions of this Indenture.

                                      -34-
<PAGE>
 
          (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.

     The provisions of this Section 3.7(b) may be made applicable to any series
of Securities pursuant to Section 3.1 (with such modifications, additions or
substitutions as may be specified pursuant to such Section 3.1). The interest
rate (or the spread or spread multiplier used to calculate such interest rate,
if applicable) on any Security of such series may be reset by the Company on the
date or dates specified on the face of such Security (each an "Optional Reset
Date"). The Company may exercise such option with respect to such Security by
notifying the Trustee of such exercise at least 45 but not more than 60 days
prior to an Optional Reset Date for such Security. Not later than 40 days prior
to each Optional Reset Date, the Trustee shall transmit, in the manner provided
for in Section 1.6, to the Holder of any such Security a notice (the "Reset
Notice") indicating whether the Company has elected to reset the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable), and if so (i) such new interest rate (or such new spread or spread
multiplier, if applicable) and (ii) the provisions, if any, for redemption
during the period from such Optional Reset Date to the next Optional Reset Date
or, if there is no such next Optional Reset Date, to the Stated Maturity of such
Security (each such period a "Subsequent Interest Period"), including the date
or dates on which or the period or periods during which and the price or prices
at which such redemption may occur during the Subsequent Interest Period.

     Notwithstanding the foregoing, not later than 20 days prior to the Optional
Reset Date, the Company may, at its option, revoke the interest rate (or the
spread or spread multiplier used to calculate such interest rate, if applicable)
provided for in the Reset Notice and establish an interest rate (or a spread or
spread multiplier used to calculate such interest rate, if applicable) that is
higher than the interest rate (or the spread or spread multiplier, if
applicable) provided for in the Reset Notice, for the Subsequent Interest Period
by causing the Trustee to transmit, in the manner provided for in Section 1.6,
notice of such higher interest rate (or such higher spread or spread multiplier,
if applicable) to the Holder of any such Security. Such notice shall be
irrevocable. All Securities with respect to which the interest rate (or the
spread or spread multiplier used to calculate such interest rate, if applicable)
is reset on an Optional Reset Date, and with respect to which the Holders of
such Securities have not tendered such Securities for repayment (or have validly
revoked any such tender) pursuant to the next succeeding paragraph, will bear
such higher interest rate (or such higher spread or spread multiplier, if
applicable).

     The Holder of any such Security will have the option to elect repayment by
the Company of the principal of such Security on each Optional Reset Date at a
price equal to the principal amount thereof plus interest accrued to such
Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the
Holder must follow the procedures set forth in Article Thirteen for repayment at
the option of Holders except that the period for delivery or notification to the
Trustee 

                                      -35-
<PAGE>
 
shall be at least 25 but not more than 35 days prior to such Optional Reset Date
and except that, if the Holder has tendered any Security for repayment pursuant
to the Reset Notice, the Holder may, by written notice to the Trustee, revoke
such tender or repayment until the close of business on the tenth day before
such Optional Reset Date.

     (a) Subject to the foregoing provisions of this Section 3.7 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.

     SECTION 3.8  Optional Extension of Maturity.  The provisions of this 
Section 3.8 may be made applicable to any series of Securities pursuant to
Section 3.1 (with such modifications, additions or substitutions as may be
specified pursuant to such Section 3.1). The Stated Maturity of any Security of
such series may be extended at the option of the Company for the period or
periods specified on the face of such Security (each, an "Extension Period") up
to but not beyond the date (the "Final Maturity") set forth on the face of such
Security. The Company may exercise such option with respect to any Security by
notifying the Trustee of such exercise at least 30 but not more than 60 days
prior to the Stated Maturity of such Security in effect prior to the exercise of
such option (the "Original Stated Maturity"). If the Company exercises such
option, the Trustee shall transmit, in the manner provided for in Section 1.6,
to the Holder of any such Security not later than 40 days prior to the Original
Stated Maturity a notice (the "Extension Notice") indicating (i) the election of
the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii)
the interest rate, if any, applicable to the Extension Period and (iv) the
provisions, if any, for redemption during such Extension Period. Upon the
Trustee's transmittal of the Extension Notice, the Stated Maturity of such
Security shall be extended automatically and, except as modified by the
Extension Notice and as described in the next paragraph, such Security will have
the same terms as prior to the transmittal of such Extension Notice.

     Notwithstanding the foregoing, not later than 20 days before the Original
Stated Maturity of such Security, the Company may, at its option, revoke the
interest rate provided for in the Extension Notice and establish a higher
interest rate for the Extension Period by causing the Trustee to transmit, in
the manner provided for in Section 1.6, notice of such higher interest rate to
the Holder of any such Security. Such notice shall be irrevocable. All
Securities with respect to which the Stated Maturity is extended will bear such
higher interest rate.

     If the Company extends the Stated Maturity of any Security, the Holder will
have the option to elect repayment of such Security by the Company on the
Original Stated Maturity at a price equal to the principal amount thereof, plus
interest accrued to such date.  In order to obtain repayment on the Original
Stated Maturity once the Company has extended the Stated Maturity thereof, the
Holder must follow the procedures set forth in Article Thirteen for repayment at
the option of Holders, except that the period for delivery or notification to
the Trustee shall be at least 25 but not more than 35 days prior to the Original
Stated Maturity and except that, if the Holder has tendered any Security for
repayment pursuant to an Extension Notice, the Holder may by written notice to
the Trustee 

                                      -36-
<PAGE>
 
revoke such tender for repayment until the close of business on the tenth day
before the Original Stated Maturity.

     SECTION 3.9  Persons Deemed Owners.  Prior to due presentment of a 
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium, if any) and (subject to
Section 3.5 and 3.7) any interest on such Registered Security and for all other
purposes whatsoever, whether or not such Registered Security is 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 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.

     None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

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

     SECTION 3.10  Cancellation.  All Securities and coupons surrendered for 
payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may
deliver to the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. If the Company shall so acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation. No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in 

                                      -37-
<PAGE>
 
this Section, except as expressly permitted by this Indenture. All canceled
Securities and coupons held by the Trustee shall be disposed of as directed by a
Company Order.

     SECTION 3.11  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 3.12  Currency and Manner of Payments in Respect of Securities.

     (a) Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, with respect to Registered Securities of any series not permitting
the election provided for in paragraph (b) below or the Holders of which have
not made the election provided for in paragraph (b) below, and with respect to
Bearer Securities of any series, except as provided in paragraph (d) below,
payment of the principal of (and premium, if any) and interest, if any, on any
Registered or Bearer Security of such series will be made in the Currency in
which such Registered Security or Bearer Security, as the case may be, is
payable. The provisions of this Section 3.12 may be modified or superseded with
respect to any Securities pursuant to Section 3.1.

     (b) It may be provided pursuant to Section 3.1 with respect to Registered
Securities of any series that Holders shall have the option, subject to
paragraphs (d) and (e) below, to receive payments of principal of (or premium,
if any) or interest, if any, on such Registered Securities in any of the
Currencies which may be designated for such election by delivering to the
Trustee for such series of Registered Securities a written election with
signature guarantees and in the applicable form established pursuant to Section
3.1, not later than the close of business on the Election Date (as defined
below) immediately preceding the applicable payment date. If a Holder so elects
to receive such payments in any such Currency, such election will remain in
effect for such Holder or any transferee of such Holder until changed by such
Holder or such transferee by written notice to the Trustee for such series of
Registered Securities (but any such change must be made not later than the close
of business on the Election Date immediately preceding the next payment date to
be effective for the payment to be made on such payment date and no such change
of election may be made with respect to payments to be made on any Registered
Security of such series with respect to which an Event of Default has occurred
or with respect to which the Company has deposited funds pursuant to Article
Four or Fifteen or with respect to which a notice of redemption has been given
by the Company or a notice of option to elect repayment has been sent by such
Holder or such transferee). Any Holder of any such Registered Security who shall
not have delivered any such election to the Trustee of such series of Registered
Securities not later than the close of business on the applicable Election Date
will be paid the amount due on the applicable payment date in the relevant
Currency as provided in Section 3.12(a). The Trustee for each such series of
Registered Securities shall notify the Exchange Rate Agent as soon as
practicable after the Election Date of the aggregate principal amount of
Registered Securities for which Holders have made such written election.

                                      -38-
<PAGE>
 
     (c) Unless otherwise specified pursuant to Section 3.1, if the election
referred to in paragraph (b) above has been provided for pursuant to Section
3.1, then, unless otherwise specified pursuant to Section 3.1, not later than
the fourth Business Day after the Election Date for each payment date for
Registered Securities of any series, the Exchange Rate Agent will deliver to the
Company a written notice specifying the Currency in which Registered Securities
of such series are payable, the respective aggregate amounts of principal of
(and premium, if any) and interest, if any, on the Registered Securities to be
paid on such payment date, specifying the amounts in such Currency so payable in
respect of the Registered Securities as to which the Holders of Registered
Securities denominated in any Currency shall have elected to be paid in another
Currency as provided in paragraph (b) above.  If the election referred to in
paragraph (b) above has been provided for pursuant to Section 3.1 and if at
least one Holder has made such election, then, unless otherwise specified
pursuant to Section 3.1, on the second Business Day preceding such payment date
the Company will deliver to the Trustee for such series of Registered Securities
an Exchange Rate Officer's Certificate in respect of the Dollar or Foreign
Currency or Currencies amount receivable by Holders of Registered Securities who
have elected payment in a Currency as provided in paragraph (b) above.  Such
amounts shall be determined by the Company on the basis of the applicable Market
Exchange Rate in effect on the second Business Day (the "Valuation Date")
immediately preceding each payment date, and such determination shall be
conclusive and binding for all purposes, absent manifest error.

     (d) If a Conversion Event occurs with respect to a Foreign Currency in
which any of the Securities are denominated or payable other than pursuant to an
election provided for pursuant to paragraph (b) above, then with respect to each
date for the payment of principal of (and premium, if any) and interest, if any,
on the applicable Securities denominated or payable in such Foreign Currency
occurring after the last date on which such Foreign Currency was used (the
"Conversion Date"), the Dollar shall be the currency of payment for use on each
such payment date.  Unless otherwise specified pursuant to Section 3.1, the
Dollar amount to be paid by the Company to the Trustee of each such series of
Securities and by such Trustee or any Paying Agent to the Holders of such
Securities with respect to such payment date shall be, in the case of a Foreign
Currency other than a currency unit, the Dollar Equivalent of the Foreign
Currency (as defined below) or, in the case of a currency unit, the Dollar
Equivalent of the Currency Unit (as defined below), in each case as determined
by the Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

     (e) Unless otherwise specified pursuant to Section 3.1, if the Holder of a
Registered Security denominated in any Currency shall have elected to be paid in
another Currency as provided in paragraph (b) above, and a Conversion Event
occurs with respect to such elected Currency, such Holder shall receive payment
in the Currency in which payment would have been made in the absence of such
election; and if a Conversion Event occurs with respect to the Currency in which
payment would have been made in the absence of such election, such Holder shall
receive payment in Dollars as provided in paragraph (d) of this Section 3.12.

     (f) "Dollar Equivalent" when used with respect to any Foreign Currency
shall be determined by the Exchange Rate Agent and shall be obtained for each
subsequent payment date by 

                                      -39-
<PAGE>
 
converting the specified Foreign Currency into Dollars at the Market Exchange
Rate on the Conversion Date.

     (g) "Dollar Equivalent" when used with respect to any Currency Unit shall
be determined by the Exchange Rate Agent and subject to the provisions of
paragraph (h) below shall be the sum of each amount obtained by converting the
Specified Amount (as defined below) of each Component Currency (as defined
below) into Dollars at the Market Exchange Rate for such Component Currency on
the Valuation Date with respect to each payment.

     (h) For purposes of this Section 3.12, the following terms shall have the
following meanings:

          A "Component Currency" shall mean any currency which, on the
     Conversion Date, was a Component Currency of the relevant currency unit,
     including, but not limited to, the Euro.  A "Specified Amount" of a
     Component Currency shall mean the number of units of such Component
     Currency or fractions thereof which were represented in the relevant
     currency unit, including, but not limited to, the Euro, on the Conversion
     Date. If after the Conversion Date the official unit of any Component
     Currency is altered by way of combination or subdivision, the Specified
     Amount of such Component Currency shall be divided or multiplied in the
     same proportion. If after the Conversion Date two or more Component
     Currencies are consolidated into a single currency, the respective
     Specified Amounts of such Component Currencies shall be replaced by an
     amount in such single currency equal to the sum of the respective Specified
     Amounts of such consolidated Component Currencies expressed in such single
     currency, and such amount shall thereafter be a Specified Amount and such
     single currency shall thereafter be a Component Currency. If after the
     Conversion Date any Component Currency shall be divided into two or more
     currencies, the Specified Amount of such Component Currency shall be
     replaced by amounts of such two or more currencies, having an aggregate
     Dollar Equivalent value at the Market Exchange Rate on the date of such
     replacement equal to the Dollar Equivalent of the Specified Amount of such
     former Component Currency at the Market Exchange Rate immediately before
     such division, and such amounts shall thereafter be Specified Amounts and
     such currencies shall thereafter be Component Currencies. If, after the
     Conversion Date of the relevant currency unit, including, but not limited
     to, the Euro, a Conversion Event (other than any event referred to above in
     this definition of "Specified Amount") occurs with respect to any Component
     Currency of such currency unit and is continuing on the applicable
     Valuation Date, the Specified Amount of such Component Currency shall, for
     purposes of calculating the Dollar Equivalent of the Currency Unit, be
     converted into Dollars at the Market Exchange Rate in effect on the
     Conversion Date of such Component Currency.

          "Election Date" shall mean the Regular Record Date for the applicable
     series of Registered Securities or at least 16 days prior to Maturity, as
     the case may be, or such other prior date for any series of Registered
     Securities as specified pursuant to Section 3.1(14) by which the written
     election referred to in Section 3.12(b) may be made.

                                      -40-
<PAGE>
 
     All decisions and determinations of the Exchange Rate Agent regarding the
Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the Currency
Unit, the Market Exchange Rate and changes in the Specified Amounts as specified
above shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive for all purposes and irrevocably binding upon the Company,
the Trustee for the appropriate series of Securities and all Holders of such
Securities denominated or payable in the relevant Currency. The Exchange Rate
Agent shall promptly give written notice to the Company and the Trustee for the
appropriate series of Securities of any such decision or determination.

     In the event that the Company determines in good faith that a Conversion
Event has occurred with respect to a Foreign Currency, the Company will
immediately give written notice thereof to the Trustee of the appropriate series
of Securities and to the Exchange Rate Agent (and such Trustee will promptly
thereafter give notice in the manner provided in Section 1.6 to the affected
Holders) specifying the Conversion Date. In the event the Company so determines
that a Conversion Event has occurred with respect to the Euro or any other
currency unit in which Securities are denominated or payable, the Company will
immediately give written notice thereof to the Trustee of the appropriate series
of Securities and to the Exchange Rate Agent (and such Trustee will promptly
thereafter give notice in the manner provided in Section 1.6 to the affected
Holders) specifying the Conversion Date and the Specified Amount of each
Component Currency on the Conversion Date. In the event the Company determines
in good faith that any subsequent change in any Component Currency as set forth
in the definition of Specified Amount above has occurred, the Company will
similarly give written notice to the Trustee of the appropriate series of
Securities and to the Exchange Rate Agent (and such Trustee will promptly
thereafter give notice in the manner provided in Section 1.6 to the affected
Holders).

     The Trustee of the appropriate series of Securities shall be fully
justified and protected in relying and acting upon information received by it
from the Company and the Exchange Rate Agent and shall not otherwise have any
duty or obligation to determine the accuracy or validity of such information
independent of the Company or the Exchange Rate Agent.

     SECTION 3.13  Appointment and Resignation of Successor Exchange Rate Agent.

     (a) Unless otherwise specified pursuant to Section 3.1, if and so long as
the Securities of any series (i) are denominated in a Foreign Currency or (ii)
may be payable in a Foreign Currency, or so long as it is required under any
other provision of this Indenture, then the Company will maintain with respect
to each such series of Securities, or as so required, at least one Exchange Rate
Agent. The Company will cause the Exchange Rate Agent to make the necessary
foreign exchange determinations at the time and in the manner specified pursuant
to Section 3.1 for the purpose of determining the applicable rate of exchange
and, if applicable, for the purpose of converting the issued Foreign Currency
into the applicable payment Currency for the payment of principal (and premium,
if any) and interest, if any, pursuant to Section 3.12.

                                      -41-
<PAGE>
 
     (b) No resignation of the Exchange Rate Agent and no appointment of a
successor Exchange Rate Agent pursuant to this Section shall become effective
until the acceptance of appointment by the successor Exchange Rate Agent as
evidenced by a written instrument delivered to the Company and the Trustee of
the appropriate series of Securities accepting such appointment executed by the
successor Exchange Rate Agent.

     (c) If the Exchange Rate Agent shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of the Exchange Rate Agent
for any cause, with respect to the Securities of one or more series, the
Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 3.1, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same Currency).

     SECTION 3.14  CUSIP Numbers.  The Company in issuing the Securities may 
use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall
indicate the "CUSIP" numbers of the Securities 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 or accuracy of such numbers either
as printed on the Securities or as contained in any notice of 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.

     SECTION 3.15  Certification by a Person Entitled to Delivery of Bearer 
Security. Whenever any provision of this Indenture or a Security contemplates
that certification be given by a Person entitled to delivery of a Bearer
Security, such certification shall be provided substantially in the form of
Exhibit A-1 and, if applicable, A-2 hereto, with only such changes as shall be
approved by the Company and consented to by the Trustee whose consent shall not
unreasonably be withheld.

     SECTION 3.16  Judgments.  The Company may provide, pursuant to Section 3.1,
for the Securities of any series that, to the fullest extent possible under
applicable law and except as may otherwise be specified as contemplated in
Section 3.1, (a) the obligation, if any, of the Company to pay the principal of
(and premium, if any) and interest on the Securities of any series and any
appurtenant coupons in a Foreign Currency, composite Currency or Dollars (the
"Designated Currency") as may be specified pursuant to Section 3.1 is of the
essence and agrees that judgments in respect of such Securities shall be given
in the Designated Currency; (b) the obligation of the Company to make payments
in the Designated Currency of the principal of (and premium, if any) and
interest on such Securities and any appurtenant coupons shall, notwithstanding
any payment in any other currency (whether pursuant to a judgment or otherwise),
be discharged only to the extent of the amount in the Designated Currency that
the Holder receiving such payment may, in accordance with normal banking
procedures, purchase with the sum paid in such other currency 

                                      -42-
<PAGE>
 
(after any premium and cost of exchange) in the country of issue of the
Designated Currency in the case of Foreign Currency or Dollars or in the
international banking community in the case of a composite currency on the
Business Day immediately following the day of such payment; (c) if the amount in
the Designated Currency that may be purchased falls short of the amount
originally due for any reason, the Company shall pay such additional amounts
needed to compensate for any short fall; and (d) any obligation of the Company
not discharged by such payment shall be due as a separate and independent
obligation and, until discharged as provided herein, shall continue in full
force and effect.


                                  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 rights to receive payments of principal (and premium, if any)
and interest thereon and any right to receive additional amounts, as provided in
Section 10.5), and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture,
when

     (1)  either

          i) all Securities theretofore authenticated, issued and delivered
and all coupons appertaining thereto (other than (i) coupons appertaining to
Bearer Securities surrendered in exchange for Registered Securities and maturing
after such exchange, surrender of which is not required or has been waived as
provided in Section 3.5; (ii) Securities which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 3.6; (iii)
coupons appertaining to Bearer Securities called for redemption or surrendered
for repayment and maturing after the relevant Redemption Date or Repayment Date,
as appropriate, surrender of which has been waived as provided in Section 11.6
or 13.3; and (iv) Securities for whose payment money has theretofore been
deposited in trust or segregated and held in trust by the Company and thereafter
repaid to the Company or discharged from such trust, as provided in Section
10.3), have been delivered to the Trustee for cancellation; or

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

               (a)  have become due and payable, or

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

                                      -43-
<PAGE>
 
               (c)  if redeemable at the option of the Company, are to be called
                    for redemption within one year under arrangements
                    satisfactory to the Trustee for the giving of notice of
                    redemption by the Trustee in the name, and at the expense,
                    of the Company,

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

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

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Trustee to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

     SECTION 4.2  Application of Trust Money.

     (a) Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 or 15.4 shall be held
in trust and applied by it, in accordance with the provisions of the Securities,
the coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto of the principal (and
premium, if any) and interest for whose payment such money has been deposited
with the Trustee.

     (b) If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article Four with respect to the Securities of any series
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the
Company's obligations under this Indenture and the Securities of such series
shall be revived and reinstated as though no deposit had occurred pursuant to
this Article Four with respect to Securities of such series until such time as
the Trustee or Paying Agent is permitted to apply all money held in trust
pursuant to this Section 4.2 with respect to Securities of such series in
accordance with this Article Four; provided, however, that if the Company makes
any payment of principal (or premium, if any) or interest on any Security of
such series following the reinstatement 

                                      -44-
<PAGE>
 
of its obligations, the Company shall be subrogated to the rights of the Holders
of Securities of such series to receive payment from the money so held in trust.


                                   ARTICLE V

                                    REMEDIES

     SECTION 5.1  Events of Default.  An "Event of Default" with respect to 
Securities of any series occurs if:

          (1) the Company defaults in the payment of any installment of interest
     upon any Security of that series or of any coupon appertaining thereto when
     it becomes due and payable, and continuance of such default for a period of
     30 days, whether or not such payment shall be prohibited by Article
     Sixteen; or

          (2) the Company defaults in the payment of the principal of (or
     premium, if any, on) any Security of that series at its Maturity, whether
     or not such payment shall be prohibited by Article Sixteen; or

          (3) the Company defaults in the deposit of any sinking fund payment,
     when and as due by the terms of a Security of that series, whether or not
     such payment shall be prohibited by Article Sixteen; or

          (4) the Company fails to comply with any of its agreements in the
     Securities or this Indenture (other than a covenant or warranty a default
     in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and such failure continues for 60 days after receipt by the
     Company of a Notice of Default; or

          (5) a decree or order by a court having jurisdiction in the premises
     shall have been entered adjudging the Company a bankrupt or insolvent, or
     approving as properly filed a petition seeking reorganization of the
     Company under any Bankruptcy Law, and such decree or order shall have
     continued undischarged and unstayed for a period of 60 days; or a decree or
     order of a court having jurisdiction in the premises for the appointment of
     a receiver or liquidator or trustee or assignee in bankruptcy or insolvency
     of the Company or of its property, or for the winding-up or liquidation of
     its affairs, shall have been entered, and such decree or order shall have
     remained in force undischarged and unstayed for a period of 60 consecutive
     days; or

          (6) the Company shall institute proceedings to be adjudicated a
     voluntary bankrupt, or shall consent to the filing of a bankruptcy
     proceeding against it, or shall file a 

                                      -45-
<PAGE>
 
     petition or answer or consent seeking reorganization under any Bankruptcy
     Law, or shall consent to the filing of any such petition, or shall consent
     to the appointment of a receiver or liquidator or trustee or assignee in
     bankruptcy or insolvency of it or of its property or shall make an
     assignment for the benefit of creditors, or shall admit in writing its
     inability to pay its debts generally as they become due; or

          (7) any other Event of Default as provided with respect to Securities
     of any particular series occurs.

     "Bankruptcy Law" means Title 11, United States Code, or any similar Federal
or state law for the relief of debtors.   "Custodian" means any receiver,
trustee, assignee, liquidator, custodian or similar official under any
Bankruptcy Law.

     A Default under clause (4) above is not an Event of Default until the
Trustee notifies the Company, or the Holders of at least 25% in principal amount
of the Outstanding Securities for that series notify the Company and the
Trustee, of the Default and the Company does not cure such Default (and such
Default is not waived) within the time specified in clause (4) above after
receipt of such notice. Any such notice must specify the Default, demand that it
be remedied and state that such notice is a Notice of Default.

     SECTION 5.2  Acceleration.  If an Event of Default with respect to 
Securities of any series at the time Outstanding (other than an Event of Default
specified in Section 5.4(5) or (6)) occurs and is continuing, then in every such
case the Trustee by notice to the Company, or the Holders of at least 25% in
principal amount of the Outstanding Securities of that series by notice to the
Company and the Trustee, may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount of such Securities as may be
specified in the terms hereof) of all of the Outstanding Securities of that
series to be immediately due and payable. Upon any such declaration, such
principal amount (or specified amount) shall be due and payable immediately. If
an Event of Default specified in Section 5.1(5) or (6) occurs and is continuing,
the principal amount (or, if any of the Securities of that series are Original
Issue Discount Securities or Indexed Securities, such portion of the principal
amount of such Securities as may be specified in the terms hereof) of all of the
Outstanding Securities of that series shall become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holders of that series. The Holders of a majority of the principal amount of the
Outstanding Securities of that series, by notice to the Trustee (and without
notice to any other Holder of that series) may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of the amounts specified in Section 5.1(1) or (2) that have become
due solely as a result of acceleration and if all amounts due to the Trustee
under Section 6.7 have been paid. No such rescission shall affect any subsequent
Default or impair any right consequent thereto.

                                      -46-
<PAGE>
 
     SECTION 5.3  Other Remedies.  If an Event of Default with respect to 
Securities of any series at the time outstanding (such Securities being referred
to herein as "Defaulted Securities") occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of the principal (and
premium, if any) and interest, if any, or to enforce the performance of any
provision of the Defaulted Securities or this Indenture.

     The Trustee may maintain a proceeding even if the Trustee does not possess
any of the Defaulted Securities or does not produce any of the Defaulted
Securities in the proceeding. A delay or omission by the Trustee or any Holder
in exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of, or acquiescence in, the
Event of Default. No remedy is exclusive of any other remedy. All available
remedies are cumulative.

     SECTION 5.4  Waiver of Past Defaults.  The Holders of a majority in 
principal amount of the Outstanding Defaulted Securities by notice to the
Trustee (and without notice to any other Holder), may waive an existing Default
and its consequences except (1) an Event of Default described in Section 5.1(1)
or (2), or (2) a Default in respect of a provision that under Section 9.2 cannot
be amended without the consent of each Holder affected. When a Default is
waived, it is deemed cured, but no such waiver shall extend to any subsequent or
other Default or impair any consequent right. This Section 5.4 shall be in lieu
of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly
excluded from this Indenture, as permitted by the TIA.

     SECTION 5.5  Control by Majority.  The Holders of a majority in principal 
amount of the Outstanding Securities of a series may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee determines in good faith is unduly prejudicial to the rights of
other Holders (it being understood that the Trustee shall have no duty to
ascertain whether or not such actions or forebearances are unduly prejudicial to
such Holders) of that series or would involve the Trustee in personal liability
unless the Trustee is offered indemnity satisfactory to it. This Section 5.5
shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is
hereby expressly excluded from this Indenture, as permitted by the TIA.

     SECTION 5.6  Limitation on Suits.  A Holder may not pursue any remedy with 
respect to this Indenture or the Securities of a series or any related coupons
unless:

          (1) the Holder has previously given to the Trustee written notice
     stating that an Event of Default is continuing;

          (2) the Holders of at least 25% in principal amount of the Outstanding
     Securities of that series make a written request to the Trustee to pursue
     the remedy;

                                      -47-
<PAGE>
 
          (3) such Holder or Holders offer to the Trustee reasonable security or
     indemnity against any loss, liability or expense satisfactory to the
     Trustee;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the notice, the request and the offer of security or indemnity;
     and

          (5) the Holders of a majority in principal amount of the Outstanding
     Securities of that series do not give the Trustee a direction inconsistent
     with the request during such 60-day period.

     A Holder of any Outstanding Securities of any series may not use this
Indenture to prejudice the rights of any other Holder of Outstanding Securities
of the same series or to obtain a preference or priority over any other Holder
of Outstanding Securities of the same series.

     SECTION 5.7  Rights of Holders to Receive Payment.  Notwithstanding any 
other provision of this Indenture, but subject to Article Sixteen, the right of
any Holder to receive payment of the principal of (and premium, if any) or
interest, if any, in respect of the Securities held by such Holder, on or after
the Stated Maturity or to bring suit for the enforcement of any such payment on
or after such Stated Maturity shall not be impaired or affected adversely
without the consent of each such Holder.

     SECTION 5.8  Collection Suit by Trustee.  If an Event of Default described 
in Section 5.1(1), (2) or (3) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount owing with respect to the Defaulted Securities and the
amounts provided for in Section 6.7; subject, however, to Article Sixteen.

     SECTION 5.9  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 of a series or the property
of the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal (and premium, if any) or interest, if
any, in respect of the Securities of that series shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Company for the payment of any
such amount) shall be entitled and empowered, by intervention in such proceeding
or otherwise,

     (a) to file and prove a claim for the whole amount of the principal (or in
the case of Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be provided in the terms thereof) (and premium,
if any) or interest, if any, and to file such other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including
any claim for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel) and of the Holders allowed in such
judicial proceeding, and

                                      -48-
<PAGE>
 
     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any Custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder of Securities of that series 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 of that series, to pay 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 any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding, provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and may be a member of any creditors'
committee.

     SECTION 5.10  Priorities.  If the Trustee collects any money pursuant to 
this Article Five in respect of a series of Securities, it shall pay out the
money in the following order:

          FIRST:  to the Trustee for costs and expenses of collection, including
     all sums paid or advanced by the Trustee hereunder and the reasonable
     compensation, expenses and disbursements of the Trustee, its agents and
     counsel and for other amounts due under Section 6.7;

          SECOND:  to holders of Senior Indebtedness to the extent required by
     Article Sixteen;

          THIRD:  to Holders for amounts due and unpaid on the Securities of
     that series for the principal (and premium, if any) or interest, if any, as
     the case may be, ratably, without preference or priority of any kind,
     according to such amounts due and payable on the Securities of that series.
     The Holders of each series of Securities denominated in Euro, any other
     composite Currency or a Foreign Currency and any matured coupons relating
     thereto shall be entitled to receive a ratable portion of the amount
     determined by the Exchange Rate Agent by converting the principal amount
     Outstanding of such series of Securities and matured but unpaid interest on
     such series of Securities in the Currency in which such series of
     Securities is denominated into Dollars at the Exchange Rate as of the date
     of declaration of acceleration of the Maturity of the Securities; and

          FOURTH:  the balance, if any, to the Company.

                                      -49-
<PAGE>
 
     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 5.10.  At least 15 days before such record
date, the Company shall mail to each Holder and the Trustee a notice that states
the record date, the payment date and amount to be paid.

     SECTION 5.11  Undertaking for Costs.  In any suit for the enforcement of 
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant (other than the Trustee) in the suit of
an undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 5.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 5.7 or a suit
by Holders of more than 10% in principal amount of the Outstanding Securities of
that series. This Section 5.11 shall be in lieu of Section 315(e) of the TIA and
such Section 315(e) is hereby expressly excluded from this Indenture as
permitted by the TIA.

     SECTION 5.12  Waiver of Stay, Extension or Usury 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 or any usury or other law
wherever enacted, now or at any time hereafter in force, which would prohibit or
forgive the Company from paying all or any portion of the principal (and
premium, if any) or any interest on any such amounts, as contemplated herein, or
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 laws 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  Certain Duties and Responsibilities.  The duties and 
responsibilities of the Trustee shall be as provided by Section 315 and 316 of
the Trust Indenture Act and this Indenture. Except during the continuance of an
Event of Default, (i) the Trustee undertakes to perform such duties and only
such duties as are specifically set forth in 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 its part, the Trustee may conclusively rely, as to
the truth of statements and 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 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.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee 

                                      -50-
<PAGE>
 
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section 6.1.

     SECTION 6.2  Notice of  Defaults.  If a default occurs hereunder with 
respect to Securities of any series, the Trustee shall give the Holders of
Securities of such series notice of such default as and to the extent provided
by Section 315(b) of 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 6.2,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.

     SECTION 6.3  Certain Rights of Trustee.  Subject to the provisions of 
Section 6.1:

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

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

     (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 to take any action hereunder, the Trustee (unless other evidence is
herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

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

     (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;

                                      -51-
<PAGE>
 
     (f) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, the Trustee shall not be bound to
make any investigation into the facts or matters stated in any resolution,
Officers' Certificate, or other certificate, statement, instrument, opinion,
report, notice, request, consent, order, approval, appraisal, bond, debenture,
note, coupon, security, or other paper or document unless requested in writing
so to do by the Holders of not less than a majority in aggregate principal
amount of the Securities then outstanding; provided that, if the payment within
a reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require reasonable indemnity
against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such examination shall be paid by the Company or,
if advanced by the Trustee, shall be repaid by the Company upon demand;

     (g) the Trustee may execute any of the trusts or powers hereunder or

     (h) the Trustee shall not be responsible for the computation of any
adjustment to the Conversion Price or for any determination as to whether an

of the performance of its powers and duties hereunder;

     (k) the Trustee shall not be bound to ascertain or inquire as to the
performance or observance of any covenants, conditions, or agreements on the
part of the Company, except as otherwise set forth herein, but the Trustee may

covenants, conditions and agreements contained herein and shall be entitled in
connection herewith to examine the books, records and premises of the Company;

event by the Company or the Holders of not less than 25% in aggregate principal
amount of the Securities 

                                      -52-
<PAGE>
 
Outstanding; as used herein, the term "actual knowledge" means the actual fact
or statement of knowing, without any duty to make any investigation with regard
thereto.

     SECTION 6.4  Not Responsible for Recitals or Issuance of Securities.  The 
recitals contained herein and in the Securities, except the Trustee's
certificates 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 shall not be responsible
for and makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or any coupons. The Trustee or any Authenticating
Agent shall not be accountable for the use or application by the Company or any
Paying Agent of Securities or the proceeds thereof.

     SECTION 6.5  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 Sections 6.8 and 6.13, 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 6.6  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 to in writing by the Company
and the Trustee.

     SECTION 6.7  Compensation and Reimbursement.  The Company agrees:

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

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

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without gross negligence or willful
     misconduct on its part, arising out of or in connection with the acceptance
     or administration of the trust or trusts hereunder, including the costs and
     expenses of defending itself against or investigating any claim or
     liability in connection with the exercise or performance of any of its
     powers or duties hereunder.

                                      -53-
<PAGE>
 
     The obligations of the Company under this Section 6.7 to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture.  As security for the performance of such
obligations of the Company, the Trustee shall have a claim prior to the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (and premium, if any,
on) or interest on particular Securities, and the Securities are hereby
subordinated to such prior claim. When the Trustee incurs expenses or renders
services in connection with an Event of Default specified in Article Five
hereof, the expenses (including reasonable fees and expenses of its counsel) and
the compensation for the service in connection therewith are intended to
constitute expense of administration under any applicable bankruptcy law.

     The Trustee shall give the Company notice of any claim or liability for
which the Trustee might be entitled to indemnification under subparagraph (3) of
this Section 6.7 within a reasonable amount of time after a trust officer of the
Trustee becomes aware of such claim or liability.

     SECTION 6.8  Disqualification; Conflicting Interests.  If the Trustee has 
or shall acquire a conflicting interest within the meaning of Section 310(b) of
the Trust Indenture Act, the Trustee shall either eliminate such interest or
resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under the Indentures, dated as of March
15, 1985, October 1, 1991 and May 1, 1995, between the Company and the Trustee.
Nothing herein shall prevent the Trustee from filing with the Commission the
application referred to in the penultimate paragraph of Section 310(b) of the
Trust Indenture Act.

     SECTION 6.9  Corporate Trustee Required; Eligibility.  There shall at all 
times be a Trustee hereunder which shall be a Person that is eligible pursuant
to Section 310(a) of the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $25,000,000 and its Corporate Trust Office is in
The City of New York, New York or in the City of Chicago, Illinois. The Trustee
hereby represents and warrants that it is currently in compliance and at all
times will remain in compliance with the foregoing requirements of this Section
6.9. 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. Neither the Company nor any
Affiliate of the Company shall serve as Trustee hereunder. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 6.9, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     SECTION 6.10  Resignation and Removal; Appointment of Successor.  No 
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this 

                                      -54-
<PAGE>
 
Article shall become effective until the acceptance of appointment by the
successor Trustee in accordance with the applicable requirements of Section
6.11.

     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 6.11 shall not have
been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

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

     If at any time:

          (1) the Trustee shall fail to comply with Section 310(b) of the Trust
     Indenture Act pursuant to Section 6.8 hereof after written request therefor
     by the Company or by any Holder who has been a bona fide Holder of a
     Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 6.9 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

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

          (4) the Trustee shall commence a voluntary case under the Federal
     bankruptcy laws, as now or hereafter constituted, or any other applicable
     Federal or state bankruptcy, insolvency or similar law or shall consent to
     the appointment of or taking possession by a receiver, custodian,
     liquidator, assignee, trustee, sequestrator (or other similar official) of
     the Trustee or its property or affairs, or shall make an assignment for the
     benefit of creditors, or shall admit in writing its inability to pay its
     debts generally as they become due, or shall take corporate action in
     furtherance of any such action,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 5.14, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, or the Trustee,
petition any court of competent jurisdiction for the removal of the Trustee with
respect to all Securities and the appointment of a successor Trustee or
Trustees.

     If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the 

                                      -55-
<PAGE>
 
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 6.11. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, or the Trustee, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

     The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 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 6.11  Acceptance of Appointment by Successor.  In case of the 
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee so appointed shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.

     In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall 

                                      -56-
<PAGE>
 
be deemed necessary or desirable to confirm that all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series as to which the retiring Trustee is not retiring shall continue to
be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
first two paragraphs of this Section 6.11, as the case may be.

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

     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 of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article and
under the Trust Indenture Act, 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  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
Section 311(a) of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor), excluding any creditor
relationships described in Section 311(b) of the Trust Indenture Act. A Trustee
who resigned or has been removed shall be subject to Section 311(a) of the Trust
Indenture Act to the extent indicated therein.

                                      -57-
<PAGE>
 
     SECTION 6.14  Appointment of Authenticating Agent.  The Trustee may appoint
an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue and 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 acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then,
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.14, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section 6.14, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.14, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve, as their names and addresses appear in the Security Register.
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 6.14.

                                      -58-
<PAGE>
 
     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 6.7.

     If an appointment with respect to one or more series is made pursuant to
this Section 6.14, 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 Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Registered Holders contained in the most
recent list furnished to the Trustee as provided in Section 7.1 and the names
and addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.1 upon receipt of a new list so furnished.  The Trustee shall preserve
for at least two years the names and addresses of Holders of Bearer Securities
filed with the Trustee by such Holders.

     The rights of the Holders to communicate with other Holders with respect to
their rights under this Indenture or under the Securities, and the corresponding
rights and privileges of the Trustee, shall be as provided by Section 312(b) of
the Trust Indenture Act.

     Every Holder of Securities or coupons, by receiving and holding the same,

disclosure of information as to names and addresses of Holders made pursuant to
the Trust Indenture Act.

such reports concerning the Trustee and its actions under this Indenture as may
be required pursuant to Section 313 of the Trust Indenture Act at the times and
in the manner provided pursuant thereto, if so required.

     A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each stock exchange upon which any

will notify the Trustee when any Securities are listed on any stock exchange.

     SECTION 7.4  Reports by Company.  The Company shall file with the Trustee

other reports, and such summaries thereof, as may be required pursuant to
Section 314(a) of the Trust Indenture Act at the times and in the manner
provided pursuant to the TIA; provided that any such information, documents or
reports required to be filed with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act shall be filed with the Trustee within 15 days after the
same is so required to be filed with the Commission.


                                 ARTICLE VIII

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

Company shall not consolidate with or merge into any other Person or convey,
transfer or lease all or substantially all of its properties and assets to any

     partnership or trust, shall be organized and validly existing under the
     laws of the United States of America, any State thereof or the District of
     Columbia and shall expressly assume, by an indenture supplemental hereto,
     executed and delivered to the Trustee, in form satisfactory to the Trustee,
     the due and punctual payment of the principal of (and premium, if any) and
     interest on all the Securities and the performance or observance of every
     covenant of this Indenture on the part of the Company to be performed or
     observed;

          (2)  immediately after giving effect to such transaction and treating
     any indebtedness which becomes an obligation of the Company or any
     Subsidiary as a result of such transaction as having been incurred by the
     Company or such Subsidiary at the time of such transaction, no Event of
     Default, and no event which, after notice or lapse of time or both, would
     become an Event of Default, shall have happened and be continuing;

          (3) if, as a result of any such consolidation or merger or such
     conveyance, transfer or lease, properties or assets of the Company would
     become subject to a mortgage, pledge, lien, security interest or other
     encumbrance which would not be permitted by this Indenture, the Company or
     such successor Person, as the case may be, shall take such steps as shall
     be necessary to effectively secure the Securities equally and ratably with
     (or prior to) all indebtedness secured thereby; and

          (4) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that such consolidation, merger,

consolidation or into which the Company is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein,
and thereafter the predecessor Person shall be relieved of all obligations and
covenants under this Indenture and the Securities and coupons. Upon delivery of 
an Opinion of Counsel reasonably satisfactory to the Trustee, the 

                                     -61-

                        SUPPLEMENTAL INDENTURES SECTION

     SECTION 9.1  Supplemental Indentures Without Consent of Holders.  Without 
the consent of any Holders of Securities or coupons, the Company, when
authorized by a Board Resolution, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

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

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

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

          (4) to add to, change or eliminate any of the provisions of this
     Indenture to provide that Bearer Securities may be registrable as to
     principal, to change or eliminate any restrictions on the payment of
     principal (or premium, if any) on Registered Securities or of principal (or
     premium, if any) or any interest on Bearer Securities, to permit Bearer
     Securities to be issued in exchange for Registered Securities of other
     authorized denominations or to permit or facilitate the issuance of
     Securities in uncertificated form; provided that any such action shall not
     adversely affect the interests of the Holders of Securities of any series
     or any related coupons in any material respect; or

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

                                      -62-
<PAGE>
 
          (6) to establish the form or terms of Securities of any series as
     permitted by Sections 2.1 and 3.1; or

          (7) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to add to or change any of the provisions of this Indenture
     as shall be necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one Trustee, pursuant to the requirements
     of Section 6.11; or

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

          (9)  to comply with the requirements of the Commission in order to
     effect or maintain the qualification of this Indenture under the Trust
     Indenture Act.

     SECTION 9.2  Supplemental Indentures With Consent of Holders.  With the 
consent of the Holders of a majority in principal amount of the Outstanding
Securities of each series affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, when
authorized by a Board Resolution, and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of modifying in any manner the rights of the Holders of Securities of such
series under this Indenture; provided, however, that no such supplemental
indenture shall without the consent of the Holder of each Outstanding Security
affected thereby:

          (1) change the Stated Maturity of the principal of, or any installment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof (or premium, if any) or the rate of interest thereon or any
     premium payable upon the redemption thereof, or repayment thereof, or
     change any obligation of the Company to pay additional amounts pursuant to
     Section 10.5 (except as contemplated by Section 8.1(1) and permitted by
     Section 9.1(1)) or reduce the amount of the principal of an Original Issue
     Discount Security that would be due and payable upon a declaration of
     acceleration of the Maturity thereof pursuant to Section 5.2, or  change
     any Place of Payment where, or the Currency in which, any Security (or
     premium, if any) or interest thereon is payable, or impair the right to
     institute suit for the enforcement of any such payment on or after the
     Stated Maturity thereof (or, in the case of redemption or repayment, on or
     after the Redemption Date or Repayment Date, as applicable); or

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

                                      -63-
<PAGE>
 
     or the consent of whose Holders is required for any waiver (of compliance
     with certain provisions of this Indenture or certain defaults hereunder and
     their consequences) provided for in this Indenture or reduce the quorum or
     voting requirements of Section 14.4; or

          (3) modify any of the provisions of this Section 9.2 or Section 5.13,
     except to increase any such percentage or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected thereby,
     provided, however, that this clause shall not be deemed to require the
     consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section 9.2, or the deletion of
     this proviso, in accordance with the requirements of Section 6.11 and
     9.1(8); or

          (4) modify any of the provisions of this Indenture relating to the
     subordination of the Securities in a manner adverse to the Holders without
     the consent of all Holders.  A supplemental indenture which changes or
     eliminates any covenant or other provision of this Indenture which has
     expressly been included solely for the benefit of one or more particular
     series of Securities, or which modifies the rights of the Holders of
     Securities of such series with respect to such covenant or other provision,
     shall be deemed not to affect the rights under this Indenture of the
     Holders of Securities of any other series.  A supplemental indenture may
     not make any change that adversely affects the rights under Article Sixteen
     of any holder of Senior Indebtedness then outstanding unless the requisite
     holders of such Senior Indebtedness consent to such change pursuant to the
     terms of such Senior Indebtedness.  It shall not be necessary for any Act
     of Holders under this Section to approve the particular form of any
     proposed supplemental indenture, but it shall be sufficient if such Act
     shall approve the substance thereof .

     SECTION 9.3  Execution of Supplemental Indentures.  In executing, or 
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
6.1) shall be fully protected in relying upon, an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by
this Indenture. The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

     SECTION 9.4  Effect of Supplemental Indentures.  Upon the execution of any
supplemental indenture under this Article, this Indenture shall be modified in
accordance therewith, and such supplemental indenture shall form a part of this
Indenture for all purposes; and every Holder of Securities theretofore or
thereafter authenticated and delivered hereunder shall be bound thereby.

     SECTION 9.5  Conformity With Trust Indenture Act.  Every supplemental 
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

                                      -64-
<PAGE>
 
     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 bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company or the Trustee 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  Notice of Supplemental Indenture.  Promptly after the 
execution by the Company and the Trustee of any supplemental indenture pursuant
to Section 9.2, the Company shall transmit to the Holders a notice setting forth
the substance of such supplemental indenture.


                                   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 the principal of (and premium, if any) and interest on
the Securities of that series in accordance with the terms of the Securities,
any appurtenant coupons and this Indenture. Any interest due on Bearer
Securities on or before Maturity, other than additional amounts, if any, payable
as provided in Section 10.5 in respect of principal of (or premium, if any, on)
such a Security, shall be payable only upon presentation and surrender of the
several coupons for such interest installments as are evidenced thereby as they
severally mature. Unless otherwise specified with respect to Securities of any
series pursuant to Section 3.1, at the option of the Company, all payments of
principal may be paid by check to the registered Holder of the Registered
Security or other person entitled thereto against surrender of such Security.
Unless otherwise specified as contemplated 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 of the several
coupons for such interest installments as are evidenced thereby as they
severally mature.

     SECTION 10.2  Maintenance of Office or Agency.  The Company will maintain 
in each Place of Payment for any series of Securities an office or agency where
Securities of that series (but, except as otherwise provided below, unless such
Place of Payment is located outside the United States, not Bearer Securities)
may be presented or surrendered for payment, where Securities of that series may
be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company will maintain, subject to any laws or regulations
applicable thereto, an office or agency in a Place of Payment for such series
which is located outside the United States where Securities of such series and
the related coupons may be presented and surrendered for payment (including
payment of any additional amounts payable on Securities of such series pursuant
to Section 10.5);  provided, however, that if the 

                                      -65-
<PAGE>
 
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, so
long as the Securities of such series are listed on such exchange. The Company
will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands, 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 10.5) at the place specified for the purpose
pursuant to Section 3.1(5).

     No payment of principal of, (or premium, if any) or interest on Bearer
Securities shall be made at any office or agency of  the Company in the United
States or by check mailed to any address in the United States or by transfer to
an account maintained with a bank located in the United States; provided,
however, payment of principal of and any premium and interest denominated in
Dollars (including additional amounts payable in respect thereof) on any Bearer
Security may be made at an office or agency of, and designated by, the Company
located in the United States if (but only if) payment of the full amount of such
principal, premium, interest or additional amounts in Dollars at all offices
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 and the Trustee receives an Opinion of
Counsel that such payment within the United States is legal. Unless otherwise
provided as contemplated by Section 3.1 with respect  to any series of
Securities, at the option of the Holder of any Bearer Security or related
coupon, payment may be made by check in the Currency designated for such payment
pursuant to the terms of such Bearer Security presented or mailed to an address
outside the United States or by transfer to an account in such Currency
maintained by the payee with a bank located outside the United States.

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

     SECTION 10.3  Money For Securities Payments to Be Held in Trust.  If the 
Company, a Subsidiary or any of their respective Affiliates, shall at any time
act as its own Paying Agent with respect to any series of Securities, it will,
on or before each due date of the principal of (or premium, if any) or interest
on any of the Securities of that series, segregate and hold in trust for 

                                      -66-
<PAGE>
 
the benefit of the Persons entitled thereto a sum sufficient to pay the
principal (and premium, if any) and interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided and
will promptly notify the Trustee of its action or failure so to act. Whenever
the Company shall have one or more Paying Agents for any series of Securities,
it will, prior to each due date of the principal of (or premium, if any) or
interest on any Securities of that series, and any appurtenant coupons, deposit
with a Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section 10.3, that such Paying Agent will (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series and any appurtenant coupons, and upon the written
request of the Trustee, forthwith pay to the Trustee all sums held in trust by
such Paying Agent for payment in respect of the Securities of that series.

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

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

     SECTION 10.4  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 

                                      -67-
<PAGE>
 
permit any Subsidiary 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 10.5  Payment of 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 any series or any coupon appertaining thereto
additional amounts upon the terms and subject to the conditions provided
therein. Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of (or premium, if any) or interest on, or in respect
of, any Security of any series, 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 the terms of such Securities and this Section 10.5 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 payment of principal (and
premium, if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) 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 Paying Agent or Paying
Agents, if other than the Trustee, with an Officer's Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of principal
of (and premium, if any) or interest on the Securities of that series shall be
made to Holders of Securities of that series or the 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, if any, required
by the terms of such Securities and the first paragraph of this Section 10.5.
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 bad faith 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 10.5.

     SECTION 10.6  Statement by Officers as to Default.

     (a) The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and 

                                      -68-
<PAGE>
 
observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of force provided
hereunder), and if the Company shall be in default, specifying all such defaults
and the nature and status thereof of which they may have knowledge.

     (b) The Company shall deliver to the Trustee as soon as possible, and in
any event within five days after the Company becomes aware or should reasonably
have become aware of the occurrence of any Default or Event of Default, an
Officers' Certificate specifying such Default or Event of Default, the period of
existence thereof and what action the Company is taking or proposes to take with
respect thereto.

     SECTION 10.7  Existence.  Subject to Article Eight, the Company will do or 
cause to be done all things necessary to preserve and keep in full force and
effect its existence, 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.

                                  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 a Board Resolution. In
case of any redemption at the election of the Company of less than all the
Securities of any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

     SECTION 11.3  Selection by Trustee of Securities to Be Redeemed.  Except as
otherwise specified or contemplated by Section 3.1 for Securities of any series,
if less than all the Securities of any series are to be redeemed (unless all of
the Securities of such series and of a specified 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 not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series (so long as such method is
not prohibited by the rules of any stock exchange on which the Securities are
then listed). If less than all of the Securities of such series and of a
specified 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 specified tenor not
previously called for redemption in accordance with the preceding sentence.  The
Trustee shall promptly notify the Company 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.

                                      -70-
<PAGE>
 
     SECTION 11.4  Notice of Redemption.  Notice of redemption shall be given in
the manner provided in Section 1.6 not less than 30 nor more than 60 days prior
to the Redemption Date, to each Holder of Securities to be redeemed.

     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 of
     any Securities, the principal amounts) of the particular Securities to be
     redeemed,

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

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

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

          (7) that Bearer Securities may be surrendered for payment only at such
     place or places outside of the United States, except as otherwise specified
     in Section 10.2 and unless otherwise specified in such notice, Bearer
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all coupons maturing subsequent to the date fixed for
     redemption or the amount of any such missing coupon or coupons will be
     deducted from the Redemption Price, unless security or indemnity
     satisfactory to the Company, the Trustee for such series and any Paying
     Agent is furnished,

          (8) if Bearer Securities of any series are to be redeemed and any
     Registered Securities of such series are not to be redeemed, and if such
     Bearer Securities may be exchanged for Registered Securities not subject to
     redemption on this Redemption Date pursuant to Section 3.5 or otherwise,
     the last date, as determined by the Company, on which such exchanges may be
     made, and

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

     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 

                                      -71-
<PAGE>
 
of the Company and shall be irrevocable. Failure to give such notice to the
Holder of any Security or any defect in such notice given to the Holder of any
Security shall not affect the validity of the proceedings for any other Security
or part thereof.

     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 in the Currency in which such
Securities are payable sufficient to pay the Redemption Price of, and (except if
the Redemption Date shall be an Interest Payment Date) accrued interest on, all
the Securities which are to be redeemed on that date.

     SECTION 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. Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that installments of interest on Bearer Securities whose
Stated Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of coupons for such interest (at an office or agency
located outside the United States except as otherwise provided in Section 10.2)
and provided further, that, unless otherwise specified in 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 Registered
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 Bearer
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 Bearer
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 without
interest thereon; provided, however, that interest represented by coupon shall
be payable only upon presentation and surrender of those coupons at an office or
agency located outside of the United States except as otherwise provided in
Section 10.2.  If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) 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 

                                      -72-
<PAGE>
 
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 may (1) deliver Outstanding Securities of a series (other than any
previously called for redemption), together with any unmatured coupons
appertaining to any Bearer Securities of such series and (2) 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
(unless a shorter period is satisfactory to the Trustee), 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 

                                      -73-
<PAGE>
 
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 30 nor more than 60 days before
each such sinking fund payment date the Trustee shall select the Securities to
be redeemed upon such sinking fund payment date (unless a shorter period is
satisfactory to the Trustee) 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.


                                 ARTICLE XIII

                       REPAYMENT AT THE OPTION OF HOLDERS

     SECTION 13.1  Applicability of Article.  Securities of any series which are
repayable at the option of the Holders thereof before their Stated Maturity
shall be repaid in accordance with their terms and (except as otherwise
specified pursuant to Section 3.1 for Securities of such series) in accordance
with this Article.

     SECTION 13.2  Repayment of Securities.  Each Security which is subject to 
repayment in whole or in part at the option of the Holder thereof on a Repayment
Date shall, unless otherwise provided in its terms, be repaid at the applicable
Repayment Price together with interest accrued to such Repayment Date as
specified pursuant to Section 3.1.

     SECTION 13.3  Exercise of Option; Notice.  Each Holder desiring to exercise
such Holder's option for repayment shall, as conditions to such repayment,
surrender the Security to be repaid in whole or in part together with written
notice of the exercise of such option at any office or agency of the Company in
a Place of Payment, not less than 30 nor more than 45 days prior to the
Repayment Date; provided, however, that surrender of Bearer Securities together
with written notice of exercise of such option shall be made at an office or
agency located outside the United States except as otherwise provided in Section
10.2. Such notice, which shall be irrevocable, shall specify the principal
amount of such Security to be repaid, which shall be equal to the minimum
authorized denomination for such Security or an integral multiple thereof, and
shall identify the Security to be repaid and, in the case of a partial repayment
of the Security, shall specify the denominations of the Security or Securities
of the same series to be issued to the Holder for the portion of the principal
of the Security surrendered which is not to be repaid.

     If any Bearer Security surrendered for repayment shall not be accompanied
by all unmatured coupons and all matured coupons in default, such Bearer
Security may be paid after deducting from the Repayment 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 Bearer
Security shall surrender to the 

                                      -74-
<PAGE>
 
Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Repayment Price, such Holder shall be
entitled to receive the amount so deducted without interest thereon; 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.

     The Company shall execute and the Trustee, upon Company Order, shall
authenticate and deliver without service charge to the Holder of any Registered
Security so surrendered a new Registered Security or Securities of the same
series, of any authorized denomination specified in the foregoing notice, in an
aggregate principal amount equal to any portion of the principal of the
Registered Security so surrendered which is not to be repaid.

     The Company shall execute and the Trustee, upon Company Order, shall
authenticate and deliver without service charge to the Holder of any Bearer
Security so surrendered a new Registered Security or Securities or new Bearer
Security or Securities (and all appurtenant unmatured coupons and matured
coupons in default) or any combination thereof of the same series of any
authorized denomination or denominations specified in the foregoing notice, in
an aggregate principal amount equal to any portion of the principal of the
Security so surrendered which is not to be paid; provided, however,  that the
issuance of a Registered Security therefor shall be subject to applicable laws
and regulations in effect at the time of the exchange; neither the Company, the
Trustee nor the Security Registrar shall issue Registered Securities for Bearer
Securities if it has received an Opinion of Counsel that as a result of such
issuance the Company would suffer adverse consequences under the United States
Federal income tax laws then in effect and the Company has delivered to the
Trustee a Company Order directing the Trustee not to make such issuances
thereafter unless and until the Trustee receives a subsequent Company Order to
the contrary.  The Company shall deliver copies of such Company Order to the
Security Registrar.

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

     SECTION 13.4  Election of Repayment by Remarketing Entities.  The Company 
may elect with respect to Securities of any series which are repayable at the
option of the Holders thereof before their Stated Maturity, at any time prior to
any Repayment Date to designate one or more Remarketing Entities to purchase, at
a price equal to the Repayment Price, Securities of such series from the Holders
thereof who give notice and surrender their Securities in accordance with
Section 13.3.

     SECTION 13.5  Securities Payable on the Repayment Date.  Notice of exercise
of the option of repayment having been given and the Securities so to be repaid
having been surrendered as aforesaid, such Securities shall, unless purchased in
accordance with Section 13.4, on the Repayment Date become due and payable at
the price therein specified and from and after the Repayment Date such
Securities shall cease to bear interest and shall be paid on the Repayment 

                                      -75-
<PAGE>
 
Date, and the coupons for such interest appertaining to Bearer Securities so to
be repaid, except to the extent provided above, shall be void, unless the
Company shall default in the payment of such price in which case the Company
shall continue to be obligated for the principal amount of such Securities and
shall be obligated to pay interest on such principal amount at the rate borne by
such Securities from time to time until payment in full of such principal
amount.

     SECTION 14.5  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

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, in the case of Bearer Securities, 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.
 
          (A) The Trustee shall, by an instrument in writing, appoint a
     temporary chairperson of the meeting, unless the meeting shall have been
     called by the Company or by Holders of Securities as provided in Section
     14.2(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 chairperson.  A permanent chairperson and a permanent
     secretary of the meeting shall be elected by vote of the Persons entitled

<PAGE>
 
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 chairperson of the meeting shall appoint two

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 14.2 and, if

affidavits of the permanent chairperson 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 XV

                       DEFEASANCE AND COVENANT DEFEASANCE

     SECTION 15.1  Company's Option to Effect Defeasance or Covenant Defeasance.
The Company may elect, at its option by Board Resolution at any time, to have
either Section 15.2 or Section 15.3 applied to the Outstanding Securities of any
series designated pursuant to Section 3.1 as being defeasible, and any related
coupon, pursuant to this Article Fifteen (hereinafter called a "Defeasible
Series"), upon compliance with the conditions set forth below in this Article
Fifteen.

     SECTION 15.2  Defeasance and Discharge.  Upon the Company's exercise of the
option provided in Section 15.1 to have this Section 15.2 applied to the
Outstanding Securities of any Defeasible Series, the Company shall be deemed to
have been discharged from its obligations with respect to the Outstanding
Securities of such series and any related coupons as provided in this Section on
and after the date the conditions set forth in Section 15.4 are satisfied
(hereinafter called "Defeasance"). For this purpose, such Defeasance means that
the Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities of such series and to have satisfied
all its other obligations under the Securities of such series and this Indenture
insofar as the Securities of such series are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated
or discharged hereunder (1) the rights of Holders of Securities of such series
to receive, solely from the trust fund described in Section 15.4 and as more
fully set forth in such Section, payments in respect of the principal of (and
premium, if any) and interest on such Securities of such series when payments
are due, (2) the Company's obligations with respect to the Securities of such
series under Sections 3.4, 3.5, 3.6, 10.2, 10.3 and any additional amounts under
Section 10.5, (3) the rights, powers, trusts, duties and immunities of the
Trustee 

                                      -79-

hereunder and (4) this Article Fifteen. Subject to compliance with this Article
Fifteen, the Company may exercise its option provided in Section 15.1 to have
this Section 15.2 applied to the Outstanding Securities of any Defeasible Series
notwithstanding the prior exercise of its option provided in Section 15.1 to
have Section 15.3 applied to the Outstanding Securities of such series and any
related coupons.

     SECTION 15.3  Covenant Defeasance.  Upon the Company's exercise of the
option provided in Section 15.1 to have this Section 15.3 applied to the
Outstanding Securities of any Defeasible Series and any related coupons, (1) the
Company shall be released from its obligations under Section 10.7 and Section
8.1 and (2) the occurrence of any event specified in Sections 5.1(3), 5.1(4)
(with respect to either of Section 10.7 and Section 8.1) and 5.1(7) shall be
deemed not to be or result in an Event of Default, in each case with respect to
the Outstanding Securities of such series as provided in this Section 15.3 on
and after the date the conditions set forth in Section 15.4 are satisfied
(hereinafter called "Covenant Defeasance"). For this purpose, such Covenant
Defeasance means that 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)),
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 the Securities of such series shall be unaffected thereby.

     SECTION 15.4  Conditions to Defeasance or Covenant Defeasance.  The 
following shall be the conditions to application of either Section 15.2 or
Section 15.3 to the Outstanding Securities of any Defeasible Series:

          (1) The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee that satisfies the
     requirements contemplated by Section 6.9 and agree to comply with the
     provisions of this Article Fifteen applicable to it) as trust funds in
     trust for the purpose of making the following payments, specifically
     pledged as security for, and dedicated solely to, the benefit of the
     Holders of Outstanding Securities of such series, (A) money in an amount
     (in such Currency in which such Securities and any coupons appertaining
     thereto are then specified as payable at Stated Maturity), (B) U.S.
     Government Obligations that through the scheduled payment of principal and
     interest in respect thereof in accordance with their terms will provide,
     not later than one day before the due date of any payment, money in an
     amount, or (C) a combination thereof, in each case sufficient, in the
     opinion of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee, to
     pay and discharge, and which shall be applied by the Trustee (or any such
     other qualifying Trustee) to pay and discharge, the principal of (and
     premium, if any) and interest on the Securities of such series on the
     respective Stated Maturities, in accordance with the terms of this
     Indenture and the Securities of such series.

<PAGE>
 
          (2) In the case of an election under Section 15.2, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (A) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date first set forth hereinabove,
     there has been a change in the applicable Federal income tax law, in either
     case (A) or (B) to the effect that, and based thereon such opinion shall
     confirm that, the Holders of the Outstanding Securities of such series will
     not recognize gain or loss for Federal income tax purposes as a result of
     the deposit, Defeasance and discharge to be effected with respect to the
     Securities of such series and will be subject to Federal income tax on the
     same amount, in the same manner and at the same times as would be the case
     if such deposit, Defeasance and discharge were not to occur.

          (3) In the case of an election under Section 15.3, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of the Outstanding Securities of such series will not recognize
     gain or loss for Federal income tax purposes as result of the deposit and
     Covenant Defeasance to be effected with respect to the Securities of such
     series and will be subject to Federal income tax on the same amount, in the
     same manner and at the same times as would be the case if such deposit and
     Covenant Defeasance were not to occur.

          (4) The Company shall have delivered to the Trustee an Officers'
     Certificate to the effect that the Securities of such series, if then
     listed on any securities exchange, will not be delisted as a result of such
     deposit.

          (5) No Event of Default or event that (after notice of lapse of time
     or both) would become an Event of Default shall have occurred and be
     continuing at the time of such deposit or, with regard to any Event of
     Default or any such event specified in Sections 5.1(5) and (6), at any time
     on or prior to the 90th day after the date of such deposit (it being
     understood that this condition shall not be deemed satisfied until after
     such 90th day).

          (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
     to have a conflicting interest within the meaning of the Trust Indenture
     Act.

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

          (8) Such Defeasance or Covenant Defeasance shall not result in the
     trust arising from such deposit constituting an investment company within
     the meaning of the Investment Company Act of 1940, as amended, unless such
     trust shall be qualified or exempt from regulation thereunder.

                                      -81-

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

     SECTION 15.5  Deposited Money and U.S. Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions. Subject to the provisions of the last
paragraph of Section 10.3, all money and U.S. Government Obligations (including
the proceeds thereof) deposited with the Trustee or other qualifying trustee
(solely for purposes of this Section 15.5 and Section 15.6, the Trustee and any
such other trustee are referred to collectively as the "Trustee") pursuant to
Section 15.4 in respect of the Securities of any Defeasible Series and any
related coupons shall be held in trust and applied by the Trustee, in accordance
with the provisions of the Securities and the related coupons, if any, of such
series and this Indenture, to the payment, either directly or through any such
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of Securities of such series, of all sums
due and to become due thereon in respect of principal and any premium and
interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.

     Unless otherwise specified with respect to any Security pursuant to Section
3.1, if, after a deposit referred to in Section 15.4(a) has been made, (a) the
Holder of a Security in respect of which such deposit was made is entitled to,
and does, elect pursuant to Section 3.12(b) or the terms of such Security to
receive payment in a Currency other than that in which the deposit pursuant to
Section 15.4(a) has been made in respect of such Security, or (b) a Conversion
Event occurs as contemplated in Section 3.12(d) or 3.12(e) or by the terms of
any Security in respect of which the deposit pursuant to Section 15.4(a) has
been made, the indebtedness represented by such Security and any coupons
appertaining thereto shall be deemed to have been, and will be, fully discharged
and satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as the same becomes due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on the applicable Market Exchange Rate
for such Currency in effect on the second Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 15.4 or the principal and interest received in
respect thereof other than any such tax, fee or other charge that by law is for
the account of the Holders of Outstanding Securities.

     Anything in this Article Fifteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 15.4 with respect to Securities of any Defeasible Series that, 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 that would 

                                      -82-
<PAGE>
 
then be required to be deposited to effect an equivalent Defeasance or Covenant
Defeasance with respect to the Securities of such series.

     SECTION 15.6  Reinstatement.  If the Trustee or the Paying Agent is unable 
to apply any money in accordance with this Article Fifteen with respect to the
Securities of any series by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article Fifteen with respect to Securities of such
series until such time as the Trustee or Paying Agent is permitted to apply all
money held in trust pursuant to Section 15.5 with respect to Securities of such
series in accordance with this Article Fifteen; provided, however, that if the
Company makes any payment of principal of (or premium, if any) or interest on
any Security of such series following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of Securities of such
series to receive such payment from the money so held in trust.


                                  ARTICLE XVI

                          SUBORDINATION OF SECURITIES

     SECTION 16.1  Securities Subordinate to Senior Indebtedness.  The Company 
covenants and agrees, and each Holder of a Security by such Holder's acceptance
thereof likewise covenants and agrees, that, to the extent and in the manner
hereinafter set forth in this Article Sixteen, the indebtedness represented by
the Securities and the payment of the principal of (and premium, if any) and
interest, if any, in respect of each and all of the Securities are hereby
expressly made subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness.

     SECTION 16.2  Payment Over of Proceeds Upon Dissolution, Etc.  Upon any 
distribution of assets of the Company 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

          (A) any assignment for the benefit of creditors or any other
     marshalling of assets and liabilities of the Company, then and in such
     event

               (i) the holders of Senior Indebtedness shall be entitled to
          receive payment in full of all amounts due or to become due on or in
          respect of all Senior 

                                      -83-
<PAGE>
 
          Indebtedness, or provision shall be made for such payment in cash,
          before the Holders of the Securities of a series are entitled to
          receive any payment on account of the principal (and premium, if any),
          or interest, if any, in respect of the Securities of that series; and

               (ii) any payment or distribution of assets of the Company of any
          kind or character, whether in cash, property or securities, by set-off
          or otherwise, to which the Holders or the Trustee would be entitled
          but for the provisions of this Article Sixteen, including any such
          payment or distribution which may be payable or deliverable by reason
          of the payment of any other Debt of the Company being subordinated to
          the payment of the Securities of a series, shall be paid by the
          liquidating trustee or agent or other person making such payment or
          distribution, whether a trustee in bankruptcy, a receiver or
          liquidating trustee or otherwise, directly to the holders of Senior
          Indebtedness or their representative or representatives or to the
          trustee or trustees under any indenture under which any instruments
          evidencing any of such Senior Indebtedness may have been issued,
          ratably according to the aggregate amounts remaining unpaid on account
          of the principal of (and premium, if any) and interest on the Senior
          Indebtedness held or represented by each, to the extent necessary to
          make payment in full of all Senior Indebtedness remaining unpaid,
          after giving effect to any concurrent payment or distribution to the
          holders of such Senior Indebtedness.

     In the event that, notwithstanding the foregoing provisions of this Section
16.2, the Trustee or the Holder of any Security of a series shall receive 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 Debt of the Company being subordinated to the payment of the Securities of
that series, before all Senior Indebtedness is paid in full or payment thereof
provided for, and if such fact shall then 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 Indebtedness remaining unpaid, to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

     For purposes of this Article Sixteen only, the words "Cash, Property or
Securities" shall not be deemed to include shares of Capital 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 the payment
of which is subordinated, at least to the extent provided in this Article
Sixteen with respect to the Securities of the applicable series, to the payment
of all Senior Indebtedness which may at the time be outstanding; provided,
however, that (i) Senior Indebtedness is assumed by the new corporation, if any,
resulting from any such reorganization or readjustment, 

                                      -84-
<PAGE>
 
and (ii) the rights of the holders of the Senior Indebtedness are not, without
the consent of such holders, altered by such reorganization or readjustment.

     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 all or substantially all of its assets to another
person upon the terms and conditions set forth in Article Eight shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of the Company
for the purposes of this Section 16.2 if the person formed by such consolidation
or into which the Company is merged or the person which acquires by conveyance
or transfer all or substantially all of the assets of the Company, as the case
may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article Eight.

     SECTION 16.3  Acceleration of Securities.  In the event that any Securities
of a series are declared due and payable before their Stated Maturity pursuant
to Section 5.2, then and in such event the Company shall promptly notify holders
of Senior Indebtedness of such acceleration. The Company may not pay the
Securities of that series until 120 days have passed after such acceleration
occurs and may thereafter pay the Securities of that series if this Article
Sixteen permits the payment at that time. In the event that, notwithstanding the
foregoing, the Company shall make any payment to the Trustee or the Holder of
any Securities prohibited by the foregoing provisions of this Section 16.3, and
if such facts then shall have been known or thereafter shall have been made
known to the Trustee as provided in Section 16.10 or such Holder, as the case
may be, pursuant to the terms of this Indenture, then and in such event such
payment shall be paid over and delivered forthwith to the Company by or on
behalf of the person holding such payment for the benefit of the holders of
Senior Indebtedness.

     The provisions of this Section 16.3 shall not apply to any payment with
respect to which Section 16.2 would be applicable.

     SECTION 16.4  Default on Senior Indebtedness.  The Company may not make any
payment of the principal (and premium, if any) or interest, if any, in respect
of the Securities of a series and may not acquire any Securities of that series
for cash or property if:

          (1) a default on Senior Indebtedness occurs and is continuing that
     permits holders of such Senior Indebtedness to accelerate its maturity; and

          (2) the default is the subject of judicial proceedings or the Company
     receives a notice of default thereof from any person who may give such
     notice pursuant to the instrument evidencing or document governing such
     Senior Indebtedness. If the Company receives any such notice, then a
     similar notice received within nine months thereafter relating to the same
     default on the same issue of Senior Indebtedness shall not be effective for
     purposes of this Section 16.4.

                                      -85-
<PAGE>
 
     The Company may resume payments on the Securities of that series and may
acquire Securities of that series if and when:

               i)   the default is cured or waived; or

               ii)  120 or more days pass after the receipt by the Company of
                    the notice described in clause (2) above and the default is
                    not then the subject of judicial proceedings; and

this Article Sixteen otherwise permits the payment or acquisition at that time.

     In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section 16.4, and if such fact then shall have been
known or thereafter shall have been made known to the Trustee or such Holder, as
the case may be, pursuant to the terms of this Indenture, then and in such event
such payment shall be paid over and delivered forthwith to the Company by or on
behalf of the person holding such payment for the benefit of the holders of the
Senior Indebtedness.

     Nothing contained in this Article Sixteen or elsewhere in this Indenture or
in any of the Securities shall prevent the conversion by a Holder of any
Securities for Capital Stock in accordance with any provisions for conversion of
such Securities for Capital Stock in the event of an occurrence of the events
described in clauses (1) and (2) of this Section 16.4.

     The provisions of this Section 16.4 shall not apply to any payment with
respect to which Section 16.2 would be applicable.

     SECTION 16.5  Payment Permitted If No Default.  Nothing contained in this 
Article Sixteen or elsewhere in this Indenture or in any of the Securities of a
series 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 other marshalling of assets and liabilities of
the Company referred to in Section 16.2 or under the conditions described in
Section 16.3 or 16.4, from making payments at any time of the principal (and
premium, if any), or interest, if any, as the case may be, in respect of the
Securities of that series, or (b) the application by the Trustee or the
retention by any Holder of any money deposited with it hereunder to the payment
of or on account of the principal (and premium, if any), or interest, if any, as
the case may be, in respect of the Securities of that series if the Trustee did
not have, at the time provided in the proviso to the first paragraph of Section
16.10, notice that such payment would have been prohibited by the provisions of
this Article Sixteen.

     SECTION 16.6  Subrogation to Rights of Holders of Senior Indebtedness.  
Subject to the payment in full of all Senior Indebtedness, the Holders of the
Securities of a series shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article Sixteen to the rights of the holders of such 

                                      -86-
<PAGE>
 
Senior Indebtedness to receive payments or distributions of cash, property or
securities applicable to the Senior Indebtedness until the principal (and
premium, if any) or interest, if any, as the case may be, in respect of the
Securities of that series shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the Holders of the
Securities of that series or the Trustee would be entitled except for the
provisions of this Article Sixteen, and no payments pursuant to the provisions
of this Article Sixteen to the Company or to the holders of Senior Indebtedness
by Holders of the Securities of that series or the Trustee, shall, as between
the Company, its creditors other than holders of Senior Indebtedness and the
Holders of the Securities of that series, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.

     SECTION 16.7  Provisions Solely to Define Relative Rights.  The provisions 
of this Article Sixteen are and are intended solely for the purpose of defining
the relative rights of the Holders of the Securities of each series, on one
hand, and the holders of Senior Indebtedness, on the other hand. Nothing
contained in this Article Sixteen or elsewhere in this Indenture or in the
Securities of a series is intended to or shall

     (a) impair, as between the Company and the Holders of the Securities of
that series, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities of that series the principal (and
premium, if any) and interest, if any, as the case may be, in respect of the
Securities of that series as and when the same shall become due and payable in
accordance with the terms of the Securities of that series and this Indenture
and which, subject to the rights under this Article Sixteen of the holders of
Senior Indebtedness, is intended to rank equally with all other general
obligations of the Company; or

     (b) affect the relative rights against the Company of the Holders of the
Securities of that series and creditors of the Company other than holders of
Senior Indebtedness; or

          (C) prevent the Trustee or the Holder of any Security of that series
     from exercising all remedies otherwise permitted by applicable law upon
     default under this Indenture, subject to the rights, if any, under this
     Article Sixteen of the holders of Senior Indebtedness to receive cash,
     property or securities otherwise payable or deliverable to the Trustee or
     such Holder.

     SECTION 16.8  Trustee to Effectuate Subordination.  Each Holder of a 
Security by such Holder's acceptance thereof authorizes and directs the Trustee
on such Holder's behalf to take such action as may be necessary or appropriate
to effectuate the subordination provided in this Article Sixteen and appoints
the Trustee such Holder's attorney-in-fact for any and all such purposes.

     SECTION 16.9  No Waiver of Subordination Provisions.  No right of any 
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the 

                                      -87-
<PAGE>
 
Company with the terms, provisions and covenants of this Indenture, regardless
of any knowledge thereof any such holder may have or be otherwise charged with.

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

     SECTION 16.10  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 of a
series. Failure to give such notice shall not affect the subordination of the
Securities of that series to Senior Indebtedness. Notwithstanding the provisions
of this Article Sixteen or any other provision of this Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would
prohibit the making of any payment to or by the Trustee in respect of the
Securities of a series, unless and until the Trustee shall have received written
notice thereof at the address specified in Section 1.1 from the Company or a
holder of Senior Indebtedness or from any trustee or agent therefor; and, prior
to the receipt of any such written notice, the Trustee, subject to the
provisions of Article Six, shall be entitled in all respects to assume that no
such facts exist; provided, however, that if a Trust Officer of 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
(including, without limitation, the payment of the principal (and premium, if
any), or interest, if any, as the case may be, in respect of any Security of
that series), the notice with respect to such money provided for in this Section
16.10, 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 Article Six, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a person representing himself
to be a holder of Senior Indebtedness (or a trustee or agent on behalf of such
holder) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee or agent on behalf of any such holder). In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to 

                                      -88-
<PAGE>
 
this Article Sixteen, the Trustee may request such person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such person, the extent to which such person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such person under this Article Sixteen, and if such evidence is not
furnished, the Trustee may defer any payment which it may be required to make
for the benefit of such person pursuant to the terms of this Indenture pending
judicial determination as to the right of such person to receive such payment.

     SECTION 16.11  Reliance on Judicial Order or Certificate of Liquidating 
Agent. Upon any payment or distribution of assets of the Company referred to in
this Article Sixteen, the Trustee, subject to the provisions of Article Six, and
the Holders of the Securities of a series shall be entitled to conclusively 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, liquidating trustee, Custodian,
receiver, 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 of that series, for the purpose of ascertaining the persons entitled
to participate in such payment or distribution, the holders of Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Sixteen.

     SECTION 16.12  Trustee Not Fiduciary for Holders of Senior Indebtedness.  
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness and shall not be liable to any such holders if the Trustee
shall in good faith mistakenly pay over or distribute to Holders of Securities
of that series or to the Company or to any other person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article Sixteen or otherwise. The Trustee shall not be charged
with knowledge of the existence of Senior Indebtedness or of any facts that
would prohibit any payment hereunder unless a Trust Officer of the Trustee shall
have received notice to that effect at the address of the Trustee set forth in
Section 1.1. With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants or obligations as
are specifically set forth in this Article Sixteen and no implied covenants or
obligations with respect to holders of Senior Indebtedness shall be read into
this Indenture against the Trustee.

     SECTION 16.13  Rights of Trustee as Holder of Senior Indebtedness; 
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article Sixteen with respect to
any Senior Indebtedness which may at any time be held by it, to the same extent
as any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

     Nothing in this Article Sixteen shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 6.7.

                                      -89-
<PAGE>
 
     SECTION 16.14  Article Sixteen Applicable to Paying Agents.  In case at any
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
Sixteen shall in such case (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its meaning as fully for
all intents and purposes as if such Paying Agent were named in this Article
Sixteen in addition to or in place of the Trustee; provided, however, that
Sections 16.10 and 16.12 shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as Paying Agent.

                                      -90-

               (i) The Debentures in certificated form may be presented to the
               Trustee by the Property Trustee in exchange for a global
               Debenture in an aggregate principal amount equal to the aggregate
               principal amount of all Outstanding Debentures of such series (a
               "Global Debenture"), to be registered in the name of the
               Depository, or its nominee, and delivered by the Trustee to the

                                       6
<PAGE>
 
               Depository for crediting to the accounts of its participants
               pursuant to the instructions of the Regular Trustees. The Issuer
               upon any such presentation shall execute a Global Debenture in
               such aggregate principal amount and deliver the same to the
               Trustee for authentication and delivery in accordance with the
               Indenture and this First Supplemental Indenture. Payments on the
               Debentures issued as a Global Debenture will be made to the
               Depository.

               (ii) If any Preferred Securities are held in non book-entry
               certificated form, the Debentures in certificated form may be
               presented to the Trustee by the Property Trustee and any
               Preferred Security Certificate which represents Preferred
               Securities other than Preferred Securities held by the Depository
               or its nominee ("Non Book-Entry Preferred Securities") will be
               deemed to represent beneficial interests in Debentures presented
               to the Trustee by the Property Trustee having an aggregate
               principal amount equal to the aggregate liquidation amount of the
               Non Book-Entry Preferred Securities until such Preferred Security
               Certificates are presented to the Registrar for transfer or
               reissuance at which time such Preferred Security Certificates
               will be canceled and a Debenture, registered in the name of the
               holder of the Preferred Security Certificate or the transferee of
               the holder of such Preferred Security Certificate, as the case
               may be, with an aggregate principal amount equal to the aggregate
               liquidation amount of the Preferred Security Certificate
               canceled, will be executed by the Issuer and delivered to the
               Trustee for authentication and delivery in accordance with the
               Indenture and this First Supplemental Indenture. On issue of such
               Debentures, Debentures with an equivalent aggregate principal
               amount that were presented by the Property Trustee to the Trustee
               will be deemed to have been canceled.

          (b) Unless and until it is exchanged for Debentures in registered
     certificated form, a Global Debenture may be transferred, in whole but not
     in part, only by the Depository to a nominee of the Depository or by a
     nominee of the Depository to the Depository or another nominee of the
     Depository or by the Depository or any such nominee to a successor
     Depository selected or approved by the Issuer or a nominee of such
     successor Depository.

          (c) If at any time the Depository for the Debentures notifies the
     Issuer that it is unwilling or unable to continue as Depository for the
     Debentures or if at any time the Depository for the Debentures shall no
     longer be registered or in good standing as a clearing agency under the
     Securities Exchange Act of 1934, as amended, or other applicable statute or
     regulation, at a time at which the Depository is required to be so
     registered to act as Depository for the Debentures, and a successor
     Depository for such series is not appointed by the Issuer within 90 days
     after the Issuer receives such notice or becomes aware of such condition,
     as the case may be, the Issuer will execute, and, subject to Article 3 of
     the Indenture, the Trustee, upon written notice from the Issuer, will
     authenticate and deliver the Debentures in definitive registered form
     without coupons, in authorized denominations, and in an aggregate principal
     amount equal to the principal amount of the Global Debenture in exchange
     for such Global Debenture. In addition, the Issuer, in its sole discretion,
     may at any 

                                       7
<PAGE>
 
     time determine that the Debentures shall no longer be represented by a
     Global Debenture. In such event the Issuer will execute, and subject to
     Article 3 of the Indenture, the Trustee, upon receipt of an Officers'
     Certificate evidencing such determination by the Issuer, will authenticate
     and deliver the Debentures in definitive registered form without coupons,
     in authorized denominations, and in an aggregate principal amount equal to
     the principal amount of the Global Debenture in exchange for such Global
     Debenture. Upon the exchange of the Global Debenture for such Debentures in
     definitive registered form without coupons, in authorized denominations,
     the Global Debenture shall be canceled by the Trustee. Such Debentures in
     definitive registered form issued in exchange for the Global Debenture
     shall be registered in such names and in such authorized denominations as
     the Depository, pursuant to instructions from its direct or indirect
     participants or otherwise, shall instruct the Trustee in writing. The
     Trustee shall deliver such registered certificated Debentures in definitive
     form in exchange for the Global Debenture to the Depository for delivery to
     the Persons in whose names such Debentures are so registered.

     SECTION 2.5  Interest.

          (a) The Debentures will bear interest at the fixed rate of ______% per
     annum (the "Coupon Rate") from the original date of issuance or from the
     most recent Interest Payment Date to which interest has been paid or duly
     provided for until the principal thereof becomes due and payable, and on
     any overdue principal and (to the extent that payment of such interest is
     enforceable under applicable law) on any overdue installment of interest at
     the Coupon Rate, compounded quarterly, payable (subject to the provisions
     of Article IV) quarterly in arrears on March 31, June 30, September 30 and
     December 31 of each year (each, an "Interest Payment Date"), commencing on
     , 1999. Interest on the Debentures (except defaulted interest) shall be
     paid to the Persons in whose name the Debentures are registered, at the
     close of business on the regular Record Date for such interest installment
     (including Debentures that are cancelled after the Record Date and before
     the Interest Payment Date), which, with respect to any Debentures of which
     the Property Trustee is the Holder or with respect to a Global Debenture,
     shall be the close of business on the Business Day next preceding that
     Interest Payment Date.  Notwithstanding the foregoing sentence, if the
     Preferred Securities are no longer in book-entry only form or if, pursuant
     to the Indenture and this First Supplemental Indenture the Debentures are
     distributed to the holders of the Trust Securities and are not represented
     by a Global Debenture, the Issuer may select a regular Record Date for such
     interest installment which shall conform to the rules of any securities
     exchange, interdealer quotation system or other organization on which the
     Debentures are listed and which shall be more than ten Business Days but
     less than 60 Business Days before the applicable Interest Payment Date.
     Notwithstanding the foregoing, any interest that is payable at maturity
     shall be payable to the Person to whom principal payable at maturity shall
     be payable.

          (b) The amount of interest payable for any period will be computed on
     the basis of a 360-day year of twelve 30-day months, and for any period
     shorter than a full quarter on the basis of the actual number of days
     elapsed in such 90-day quarter. In the event that any date on which
     interest is payable on the Debentures is not a Business Day, then payment
     of 

                                       8
<PAGE>
 
     the interest payable on such date will be made on the next succeeding
     day which is a Business Day (and without any interest or other payment in
     respect of any such delay), except that, notwithstanding any provision of
     the Indenture to the contrary, if such Business Day is in the next
     succeeding calendar year, such payment shall be made on the immediately
     preceding Business Day, in each case with the same force and effect as if
     made on such date.

          (c) If, at any time while the Property Trustee is the Holder of any
     Debentures, the Trust or the Property Trustee is required to pay any taxes,
     duties, assessment or governmental charges of whatever nature (other than
     withholding taxes) imposed by the United States, or any other taxing
     authority, then, in any case, the Company will pay as additional interest
     ("Additional Interest") on the Debentures held by the Property Trustee,
     such additional amounts as shall be required so that the net amounts
     received and retained by the Trust and the Property Trustee after paying
     such taxes, duties, assessments or other governmental charges will be equal
     to the amounts the Trust and the Property Trustee would have received had
     no such taxes, duties, assessments or other government charges been
     imposed.

     SECTION 2.6  Authorized Denominations.  The Debentures shall be issuable in
denominations of $25 and integral multiples of $25 in excess thereof.

     SECTION 2.7 Redemption. The Debentures are not subject to conversion at the
option of the Holder. The Debentures are not subject to redemption at the option
of the Holder and are subject to redemption at the option of the Issuer or
otherwise as provided in Article III hereof.

     SECTION 2.8 Defeasance. The Debentures shall be subject to the provisions
of Articles 4 and 15 of the Indenture concerning the satisfaction and discharge
of the Issuer's indebtedness and obligations under the Indenture and the
termination of certain covenants of the Issuer under the Indenture.

     SECTION 2.9 No Sinking Fund. The Debentures shall not be entitled to the
benefit of any sinking fund or analogous provision.

     SECTION 2.10 Depository. The Depository Trust Company (or its nominee)
shall act as the initial Depository for any Global Debenture which may be issued
pursuant to this First Supplemental Indenture.


                                  ARTICLE III

provisions of Article XI of the Indenture, the Issuer shall have the right, upon

Debentures, to redeem the Debentures, in whole or in part, for cash within 90

is to be paid.

     SECTION 3.2 Optional Redemption.  Subject to the provisions of Section 
3.3 hereof and Article 11 of the Indenture, the Issuer shall have the right to

made upon not less than 30 days nor more than 60 days notice to the Holder of

or at such earlier time as the Issuer determines and specifies in the notice of

     SECTION 3.3   Partial Redemption.

     delisting of the Preferred Securities issued by the Trust from any national
     securities exchange, interdealer quotation system or other organization on
     which the Preferred Securities are then listed, the Issuer shall not be
     permitted to effect such partial redemption and may only redeem the
     Debentures in whole.

          (b) The Issuer may not redeem fewer than all of the Outstanding
     Debentures unless all accrued and unpaid interest on the Debentures has
     been paid as of the Interest Payment Date next preceding the Redemption
     Date.

          (c) If the Debentures are only partially redeemed pursuant to Section
     3.2, the Debentures will be redeemed pro rata or by lot or by any other
     method utilized by the Trustee; provided that, if at the time of redemption

                                  ARTICLE IV

                      EXTENSION OF INTEREST PAYMENT PERIOD
                      ------------------------------------


     SECTION 4.1 Extension of Interest Payment Period. The Issuer shall have the
right, at any time and from time to time during the term of the Debentures, to
defer payments of interest on the Debentures by extending the interest payment
period of the Debentures for a period not exceeding 20 consecutive quarters (the
"Extended Interest Payment Period"), during which Extended Interest Payment
Period no interest shall be due and payable; provided that no Extended Interest
Payment Period may extend beyond the Maturity Date. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to this Section 4.1, will bear
interest thereon at the Coupon Rate compounded quarterly for each quarter of the
Extended Interest Payment Period ("Compounded Interest"). At the end of the
Extended Interest Payment Period, the Issuer shall pay all interest accrued and
unpaid on the Debentures, including any Compounded Interest (all such interest
the "Deferred Interest") that shall be payable to the Holders of the Debentures
in whose names the Subordinated Debentures are registered in the Register as of
the Record Date relating to the Interest Payment Date that corresponds to the
end of such Extended Interest Payment Period. Before the termination of any
Extended Interest Payment Period, the Issuer may further extend such period,
provided that such period together with all such previous and further extensions
thereof shall not exceed 20 consecutive quarters or extend beyond the Maturity
Date. Upon the termination of any Extended Interest Payment Period and upon the
payment of all Deferred Interest then due, the Issuer may commence a new
Extended Interest Payment Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extended Interest Payment Period,
except at the end thereof, but the Issuer may prepay at any time all or any
portion of the Deferred Interest accrued during an Extended Interest Payment
Period.

     SECTION 4.2  Notice of Extension.

          (a) If the Property Trustee is the only registered Holder of the
     Debentures at the time the Issuer selects an Extended Interest Payment
     Period, the Issuer shall give written notice to the Trustee, the Regular
     Trustees and the Property Trustee of its selection of such Extended
     Interest Payment Period one Business Day before the earlier of (i) the next
     succeeding date on which Distributions on the Trust Securities are payable,
     or (ii) the date the Regular Trustees, on behalf of the Trust, are required
     to give notice of the record date, or the date such Distributions are
     payable, to holders of the Preferred Securities (or any national securities
     exchange or self-regulatory organization on which the Preferred Securities
     are listed).

          (b) If the Property Trustee is not the only Holder of the Debentures
     at the time the Issuer selects an Extended Interest Payment Period, the
     Issuer shall give the Trustee, the Property Trustee and the Holders of the
     Debentures written notice of its selection of such Extended Interest
     Payment Period 10 Business Days before the earlier of (i) the next
     succeeding Interest Payment Date, or (ii) the date the Issuer is required
     to give notice of the 

                                       11
<PAGE>
 
     record or payment date of such interest payment to the New York Stock
     Exchange or other applicable self-regulatory organization or to Holders of
     the Debentures.

          (c) The quarter in which any notice is given pursuant to paragraphs
     (a) or (b) of this Section 4.2 shall be counted as one of the 20 quarters
     permitted in the maximum Extended Interest Payment Period permitted under
     Section 4.1.

     SECTION 4.3 Limitation of Transactions. If the Issuer shall exercise its
right to defer payment of interest as provided in Section 4.1, then, prior to
the payment of all accrued interest on outstanding Debentures, the Issuer shall
not (a) declare or pay dividends on, make a distribution with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock, (b) make any payment of interest, principal or premium, if
any, on, or repay, repurchase or redeem, any debt securities issued by the
Issuer that rank equal with or junior to the Debentures or (c) make guarantee
payments with respect to the foregoing (other than pursuant to the Preferred
Securities Guarantee); provided, however, that the restriction in clause (a)
shall not apply to (i) purchases or acquisitions of the Issuer's capital stock
in connection with the satisfaction of its obligations under any employee
benefit plans, stock option plans, employee stock purchase plans or direct
reinvestment plans as may be in effect from time to time or the satisfaction of
its obligations pursuant to any contract or security outstanding on the date of
such event requiring the Issuer to purchase its capital stock (other than a
contractual obligation ranking equal with or junior to the Debentures), (ii)
reclassifications of the Issuer's capital stock or the exchange or conversion of
one class or series of the Issuer's capital stock, provided that such
reclassification, exchange or conversion does not result in a change in the
priority vis-a-vis the Preferred Securities of any class or series of capital
stock that is being so reclassified or that is the subject of such exchange or
conversion, (iii) purchases of fractional interests in shares of the Issuer's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security bring converted or exchanged, (iv) stock dividends paid by
the Issuer where the dividend stock is the same stock as that on which the
dividend is being paid or (v) redemptions or purchases of any rights pursuant to
purchase rights contained in any rights agreement as shall be in effect from
time to time, which purchase rights are substantially similar to those contained
in the Issuer's Rights Agreement dated November 5, 1998.

     waiver of a past default shall not be effective until the holders of a
     majority in liquidation amount of Trust Securities shall have consented to
     such waiver or modification; provided, however, that if the consent of the
     Holder of each Outstanding Debenture is required in connection with such
     waiver or modification, such waiver or modification shall not be effective
     until each holder of the Trust Securities shall have consented to such
     waiver or modification.

          (b) Except for any supplemental indenture provided under Section 9.1
     of the Indenture and notwithstanding anything to the contrary contained in
     Section 9.2 of the Indenture, if the Debentures are held by the Trust or by
     the Property Trustee, a supplemental indenture shall not be effective until
     the holders of not less than 66 2/3% in principal amount 

                                       21
<PAGE>
 
     of Trust Securities shall have consented to such supplemental indenture;
     provided, however, that if the consent of the Holder of each Outstanding
     Debenture is required in connection with a supplemental indenture, such
     supplemental indenture shall not be effective until each holder of the
     Trust Securities shall have consented to such supplemental indenture.

     SECTION 10.3  Acknowledgment of Rights.

     The Issuer acknowledges that, with respect to any Debentures held either by
the Trust or by the Property Trustee, if the Property Trustee fails to enforce
its rights to the fullest extent permitted by law under the Indenture, this
First Supplemental Indenture or the Debentures as the Holder of the Debentures
held as the assets of the Trust, any record holder of Preferred Securities may
institute legal proceedings directly against the Issuer to enforce the Property
Trustee's rights under the Indenture, this First Supplemental Indenture or the
Debentures without first instituting any legal proceedings against such Property
Trustee or any other person or entity. Notwithstanding the foregoing, if an
Event of Default under the Declaration has occurred and is continuing and such
event is attributable to the failure of the Issuer to pay interest or principal
on the Debentures on the date such interest or principal is otherwise payable
(or in the case of redemption, on the applicable redemption date), the Issuer
acknowledges that a holder of Preferred Securities may institute a proceeding
directly against the Issuer for enforcement of payment to the holder of the
Preferred Securities of the principal of or interest on the Debentures on or
after the respective due date specified in the Debentures, and the amount of
payment will be based on the holder's pro rata share of the amount due and owing
on all the Preferred Securities.

     SECTION 11.2 Trustee Not Responsible for Recitals. The recitals contained
herein and in the Debentures, except for the Trustee's certificate of
authentication, shall be taken as the statements of the Issuer and not of the

same. The Trustee makes no representation as to the validity or sufficiency of
this First Supplemental Indenture or of the Debentures.

     SECTION 11.3 Governing Law. This First Supplemental Indenture and each
Debenture shall be deemed to be a contract made under the laws of the State of

therein.

     SECTION 11.5 Counterparts. This First Supplemental Indenture may be
executed in any number of counterparts each of which shall be an original; but
such counterparts shall together constitute but one and the same instrument.

     Re: Registration Statement on Form S-3
         ----------------------------------

Ladies and Gentlemen:

     I am Senior Counsel in the Law Department of Motorola, Inc., a Delaware
corporation (the "Company").  I refer to the Registration Statement on Form S-3
(file no. 333-70827) (the "Registration Statement") of the Company and Motorola
Capital Trust I, a statutory business trust created under the Business Trust Act
of the State of Delaware (Del. Code Ann., tit. 12, Section 3810) (the "Trust")
to be filed with the Securities and Exchange Commission under the Securities Act
of 1933, as amended.   The Registration Statement relates to: (i) 20,000,000
shares of ___% Trust Originated Preferred Securities (the "Preferred
Securities") (liquidation amount $25 per Preferred Security) of the Trust; (ii)
___% Deferrable Interest Junior Subordinated Debentures due 2039 of the Company
(the "Debentures"); and (iii) the rights of holders of the Preferred Securities
under a guarantee (the "Preferred Securities Guarantee") by the Company.

     The Preferred Securities are to be issued pursuant to an Amended and
Restated Declaration of Trust (the "Trust Agreement"), among the Company, as
sponsor and as the issuer of the Debentures to be held by the Property Trustee,
and the regular trustees named therein.  The Preferred Securities Guarantee will
be issued pursuant to a Preferred Securities Guarantee Agreement (the "Guarantee
Agreement") by the Company, as guarantor.

     This opinion is being delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Act.  Capitalized terms used but not
otherwise defined herein have the meanings ascribed to them in the Registration
Statement.

     In connection with this opinion, I have examined originals or copies,
certified or otherwise identified to my satisfaction, of:  (i) the Registration
Statement; (ii) the Certificate of Trust of the Trust filed with the Secretary
of State of the State of Delaware on January 19, 1999; (iii) the form of the
Trust Agreement (including the designations of the terms of the Preferred
Securities annexed thereto); (iv) the form of the Preferred Securities and
specimen certificates thereof; (v) the form of the Guarantee Agreement; (vi) the
form of the subordinated indenture (the "Indenture"), between the Company and
Harris Bank & Trust Company, as indenture trustee, pursuant to which the
Subordinated Debentures will be issued; (vii) a specimen

Subordinated Debenture; (viii) the form of the Underwriting Agreement (the
"Underwriting Agreement") proposed to be entered into among the Company, the
Trust and the Underwriters named therein (collectively, the "Underwriters")
relating to, among other things, the sale of the Preferred Securities; (x) the
Amended and Restated Certificate of Incorporation of the Company, as presently
in effect; (xi) the By-Laws of the Company, as presently in effect; and (xii)
certain resolutions of the Board of Directors of the Company relating to the
issuance and sale of the Debentures and the Preferred Securities and related
matters. I have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such other documents, certificates and
records as I have deemed necessary or appropriate as a basis for the opinions
set forth herein.

     Based on and subject to the foregoing and to the other qualifications and
limitations set forth herein, I am of the opinion that when:  (i) the
Registration Statement becomes effective; (ii) the Indenture, the Declaration
and the Guarantee Agreement have been qualified under the Trust Indenture Act of
1939, as amended, (iii) the price at which the Preferred Securities are to be
sold to the Underwriters pursuant to the Underwriting Agreement and other
matters relating to the issuance and sale of the Preferred Securities and the
Debentures have been duly adopted by the Transaction Committee of the Board of
Directors of the Company; (iv) the Trust Agreement, the Underwriting Agreement,
the Guarantee Agreement and the Indenture have been duly executed and delivered
by the parties thereto; (v) the Preferred Securities have been duly executed and
authenticated in accordance with the terms of the Trust Agreement and delivered
to and paid for by the Underwriters as contemplated by the Underwriting
Agreement; and (vi) the Debentures have been duly executed and authenticated in
accordance with the terms of the Indenture and delivered to and paid for by the
Trust as contemplated by the Trust Agreement:

     1. The Guarantee Agreement will be a valid and binding obligation of the
     Company, enforceable against the Company in accordance with its terms,
     except to the extent that enforcement thereof may be limited by bankruptcy,
     insolvency, reorganization, moratorium or other similar laws affecting
     creditors rights generally or by general principles of equity (regardless
     of whether enforcement is considered at law or in equity).

     2. The issuance and sale of the Debentures will have been duly authorized
     and the Debentures will be valid and binding obligations of the Company,
     entitled to the benefits of the Indenture and enforceable against the
     Company in accordance with their terms, except to the extent that
     enforcement thereof may be limited by bankruptcy, insolvency,
     reorganization, moratorium or other similar laws affecting creditors rights
     generally or by general principles of equity (regardless of whether
     enforcement is considered at law or in equity).
