Ladies and Gentlemen:

         AMRESCO, INC., a Delaware corporation (the "Company"), proposes to
issue and sell to you (the "Underwriters") its Senior Notes due 1999 in an
aggregate principal amount of $57,500,000 (the "Notes" or the "Securities").
The Notes shall be issued under an indenture, dated as of July 1, 1996 (the
"Base Indenture"), between the Company and Comerica Bank, as trustee (the
"Trustee"), as amended and supplemented by an Officer's Certificate and Company
Order dated as of July 19, 1996 (the "Company Order"), establishing the terms
of the Notes.  The Base Indenture, as amended and supplemented by the Company
Order, is sometimes referred to herein as the "Indenture."

         The Company hereby confirms its agreement with respect to the sale of
the Securities to the Underwriters.

         1.      Registration Statement and Prospectus.  A registration
statement on Form S-3 (File No. 333-6031) with respect to the Company's Debt
Securities, Preferred Stock, Common Stock, Securities Warrants and Units (each
as defined in the Prospectus (as defined below) and collectively referred to
hereafter as the "Other Securities"), including a preliminary form of
prospectus, has been prepared by the Company in conformity with the
requirements of the Securities Act of 1933, as amended (the "Act"), and the
rules and regulations ("Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") thereunder, and has been filed with the
Commission; Amendment No. 1 to such Registration Statement, including a
preliminary form of prospectus supplement with respect to the Securities, also
has been so prepared and filed; and one or more other
<PAGE>   2
amendments or supplements to such registration statement also have been, or
will be, so prepared and filed.  Copies of such registration statement and
amendments and each related preliminary prospectus and prospectus supplement
have been delivered to the Underwriters.

         The Company has elected to rely upon Rule 430A of the Rules and
Regulations and, accordingly, will prepare and file a prospectus supplement (or
a term sheet meeting the requirements of Rule 434) pursuant to Rule 424(b) that
discloses the information previously omitted from the Prospectus (as defined
below) in reliance upon Rule 430A.  Such registration statement (including all
schedules and exhibits thereto, but excluding Form T-1) as amended at the time
it was declared effective by the Commission and, in the event of any amendment
thereto after the effective date and prior to the Closing Date (as hereafter
defined), such registration statement as so amended (but only from and after
the effectiveness of such statement), including the information (if any) deemed
to be part of the registration statement at the time of effectiveness pursuant
to Rules 430A(b) and 434(d) of the Rules and Regulations, is hereafter called
the "Registration Statement."  The prospectus included in the Registration
Statement (including any prospectus supplement relating to the Securities) at
the time it was declared effective by the Commission is hereafter called the
"Prospectus," except that if any prospectus (including any term sheet meeting
the requirements of Rule 434 of the Rules and Regulations provided by the
Company for use with a prospectus subject to completion within the meaning of
Rule 434 in order to meet the requirements of Section 10(a) of the Rules and
Regulations) filed by the Company, with the Commission pursuant to Rule 424(b)
(and Rule 434, if applicable) of the Rules and Regulations or any other such
prospectus provided to the Underwriters by the Company for use in connection
with the offering of the Securities (whether or not required to be filed by the
Company with the Commission pursuant to Rule 424(b) of the Rules and
Regulations or otherwise) differs from the prospectus on file at the time the
Registration Statement was declared effective by the Commission, the term
"Prospectus" shall refer to such differing prospectus (including any term sheet
within the meaning of Rule 434 of the Rules and Regulations) from and after the
time such prospectus is filed with the Commission or transmitted to the
Commission for filing pursuant to such Rule 424(b) (and Rule 434, if
applicable) or from and after the time it is first provided to the Underwriters
by the Company for such use.  The term "Preliminary Prospectus" as used herein
means any preliminary prospectus included in the Registration Statement
(including the preliminary prospectus supplement relating to the Securities
and supplementing that Prospectus included in the Registration Statement at the
time it was declared effective by the Commission) prior to the time it became
effective under the Act and any prospectus (including any prospectus supplement
relating to the Securities) subject to completion as described in Rule 430A or
434 of the Rules and Regulations.  Any reference herein to the Prospectus shall
be deemed to refer to and include the documents incorporated by reference
therein pursuant to Item 12 of Form S-3 under the Act as of the date of such
Prospectus.  Any reference to any amendment or supplement to the Prospectus
(including any supplement to the Prospectus) shall be deemed to refer to and
include any documents filed after the date of such Prospectus under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
incorporated therein by reference.

         2.      Representations and Warranties of the Company.  The Company
represents and warrants to, and agrees with, the several Underwriters as
follows:





                                       2
<PAGE>   3
                 (a)      No order preventing or suspending the use of any
         Preliminary Prospectus has been issued by the Commission or the
         securities authority of any state or other jurisdiction in which the
         Notes are to be offered and sold and each Preliminary Prospectus, at
         the time of filing thereof, did 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 light of the
         circumstances under which they were made, not misleading.  The
         foregoing shall not apply to statements in or omissions from any
         Preliminary Prospectus in reliance upon, and in conformity with,
         written information furnished to the Company by any Underwriter
         specifically for use in the Preliminary Prospectus as supplemented to
         relate to the Securities.

                 (b)      As of the time the Registration Statement (or any
         post-effective amendment thereto) is or was declared effective by the
         Commission, upon the filing or first delivery to the Underwriters of
         the Prospectus (or any supplement to the Prospectus (including any
         term sheet meeting the requirements of Rule 434)) and at the Closing
         Date, (i) the Registration Statement and Prospectus (in each case, as
         so amended and/or supplemented) conformed or will conform in all
         material respects to the requirements of the Act and the Rules and
         Regulations, (ii) the Registration Statement (as so amended and/or
         supplemented) will not or did not include 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,
         and (iii) the Prospectus (as so amended and/or supplemented) did not
         or will not include 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 light of the circumstances in which
         they are or were made, not misleading; except that the foregoing
         clauses (i), (ii) and (iii) shall not apply to statements in or
         omissions from any such document in reliance upon, and in conformity
         with, written information furnished to the Company by any Underwriter
         specifically for use in the preparation thereof.  The Registration
         Statement has been declared effective by the Commission; no stop order
         suspending the effectiveness of the Registration Statement has been
         issued; and no proceeding for that purpose has been initiated or, to
         the Company's knowledge, threatened by the Commission.

                 (c)      The documents incorporated by reference in the
         Prospectus, when they became effective or were filed with the
         Commission, as the case may be, conformed in all material respects to
         the requirements of the Act or the Exchange Act, as applicable, and
         the rules and regulations of the Commission thereunder, and none of
         such documents 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; and any
         further documents so filed and incorporated by reference in the
         Prospectus, or any amendment or supplement thereto, when such
         documents become effective or are filed with the Commission, as the
         case may be, will conform in all material respects to the requirements
         of the Act or the Exchange Act, as applicable, and the rules and
         regulations of the Commission thereunder 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; provided, however, that this representation
         and warranty shall not apply to the Statement of Eligibility and
         Qualification of the Trustee on Form T-1 filed as





                                       3
<PAGE>   4
         an Exhibit to the Registration Statement or to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Company by any Underwriter expressly for
         use in the Prospectus as supplemented to relate to the Securities.

                 (d)      The Indenture conforms, and any amendments or
         supplements thereto will conform, in all material respects to the
         requirements of the Trust Indenture Act of 1939, as amended (the
         "Trust Indenture Act"), and the rules and regulations of the
         Commission thereunder.

                 (e)      The consolidated financial statements of the Company,
         together with the related notes thereto, set forth or incorporated by
         reference in the Registration Statement and Prospectus comply in all
         material respects with the requirements of the Act and fairly present
         the financial condition of the Company and its Subsidiaries (as
         hereinafter defined) or its predecessor or acquired businesses, as the
         case may be, as of the dates indicated and the results of operations
         and changes in cash flows for the periods therein specified in
         conformity with generally accepted accounting principles consistently
         applied throughout the periods involved (except as otherwise stated
         therein), and the independent public accountants whose reports are
         contained therein are independent public accountants as required by
         the Act, the Exchange Act and the Rules and Regulations.  The
         financial statement schedules, if any, included in the Registration
         Statement or incorporated by reference therein, or in any
         post-effective amendment thereto, and the other financial and
         statistical information included in the Prospectus  in all material
         respects present fairly and on a basis consistent with the books and
         records of the Company the information stated therein.  The terms
         "Subsidiary" and "Material Subsidiary" shall have the meanings
         assigned thereto in the Indenture.

                 (f)      The Company has all requisite corporate power and
         authority to execute, deliver and perform its obligations under this
         Agreement.  This Agreement has been duly authorized, executed and
         delivered by the Company, and constitutes a valid, legal and binding
         obligation of the Company, enforceable in accordance with its terms,
         except as rights to indemnity and contribution hereunder may be
         limited by federal or state securities laws and subject as to
         enforcement, to applicable bankruptcy, insolvency, reorganization and
         moratorium laws and other laws relating to or affecting the
         enforcement of creditors' rights generally and to general equitable
         principles.

                 (g)      The Company has all requisite corporate power and
         authority to execute, deliver and perform its obligations under the
         Indenture and the Notes.  The Indenture has been duly and validly
         authorized by the Company and, when the Indenture has been executed
         and delivered, will be a valid and binding obligation of the Company,
         enforceable against the Company in accordance with its terms, subject,
         as to enforcement, to applicable bankruptcy, insolvency,
         reorganization and moratorium laws and other laws relating to or
         affecting the enforcement of creditors' rights generally and to
         general equitable principles.  The Notes sold hereunder have been duly
         and validly authorized by the Company and, when the Notes have been
         executed and authenticated in the manner set forth in the Indenture
         and





                                       4
<PAGE>   5
         issued, sold, and delivered in the manner set forth in the Prospectus,
         will be the valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms and the terms of
         the Indenture, subject, as to enforcement, to applicable bankruptcy,
         insolvency, reorganization and moratorium laws affecting the
         enforcement of creditors' rights generally and to general equitable
         principles.  The Indenture will have been duly qualified under the
         Trust Indenture Act upon effectiveness of the Registration Statement.
         The Indenture will be substantially in the form filed as an exhibit to
         the Registration Statement (other than as to terms included in the
         Company Order).  The Indenture and the Notes conform in all material
         respects to the descriptions thereof contained in the Registration
         Statement and the Prospectus.

                 (h)      The authorized capital stock of the Company is as set
         forth under the caption "Capitalization" in the Prospectus.  All of
         the outstanding shares of capital stock have been duly authorized,
         validly issued and are fully paid and non-assessable.  The outstanding
         securities of the Company described in the Registration Statement and
         Prospectus conform to such descriptions.  All offers and sales of the
         Company's capital stock, 8% Convertible Subordinated Debentures due
         2005 or 10% Senior Subordinated Notes due 2003 prior to the date
         hereof were at all relevant times duly registered under the Act or
         exempt from the registration requirements of the Act and were duly
         registered or the subject of an available exemption from the
         registration requirements of the applicable state securities or Blue
         Sky laws.  None of the issued shares of capital stock of the Company
         or its predecessors or any of its Subsidiaries has been issued or is
         owned or held in violation of any pre-emptive rights of shareholders,
         and no preemptive rights or similar rights of any security holders of
         the Company exist with respect to the Notes.  The Company has no
         agreement with any security holder as to which the Company has not
         obtained waiver which gives such security holder the right to require
         the Company to register under the Act any securities of any nature
         owned or held by such person in connection with the transactions
         contemplated by this Agreement.

         registered under the Registration Statement.

                 (j)      The execution, delivery and performance of this
         Agreement, the Indenture and the Securities, the issuance and delivery
         of the Securities, and the consummation of the transactions herein and
         therein contemplated will not conflict with, or result in a breach or
         violation of any of the terms and provisions of, or constitute a
         default under, (i) any statute,  (ii) any material indenture,
         mortgage, deed of trust, loan agreement or other agreement or

         Company, any Subsidiary or any of their respective properties, which
         breach, violation or default reasonably could or might be expected,
         individually or in the aggregate with other such breaches, violations
         or defaults, to result in a material adverse effect on the financial
         condition, results of operations or business of the Company and its
         Subsidiaries, taken as a whole.  Other than those already obtained or
         waivers from which have been obtained, no consent, approval,
         authorization or order of, or filing with, any court or governmental
         agency or body is required by the Company or any Subsidiary for the
         execution, delivery and performance of this Agreement, the Indenture
         or the Securities or for the consummation of the transactions
         contemplated hereby and thereby, including the issuance, sale and
         delivery of the Securities by the Company, except such as may be
         required under the Act, the Trust Indenture Act or state securities or
         blue sky laws.

                 (k)      Neither the Company nor any Subsidiary is (i) in
         violation of its respective certificate of incorporation or charter or
         its respective by-laws or other organizational documents, (ii) in
         default (nor has an event occurred which with notice or passage of
         time or both would constitute such a default) under any bond,
         indenture, mortgage, deed of trust, note, loan or credit agreement or
         other material agreement or instrument to which any of them is a party
         or by which any of them or any of their properties or assets may be
         bound or affected, (iii) in violation of any order of any court,
         arbitrator or governmental body or (iv) except as disclosed in the
         Registration Statement and the Prospectus, in violation of or has
         violated any franchise, grant, authorization, license, permit,
         judgment, decree, order, statute, rule or regulation, which, in the
         case of clauses (i)-(iv) of this sentence, would (individually or in
         the aggregate) (x) adversely affect the legality, validity or
         enforceability of this Agreement, the Indenture or the Securities, or
         any document related hereto or thereto or (y) have a material adverse
         effect on the financial condition, results of operations or business
         of the Company and the Subsidiaries, taken as a whole, or (z)
         materially impair the Company's ability to perform fully on a timely
         basis any obligations which it has under this Agreement, the Indenture
         or the Securities.  The Company or the Subsidiaries hold, and are
         operating in compliance with, all franchises, grants, authorizations,
         licenses, permits, easements, consents, certificates and orders of any
         governmental or self-regulatory body required for the conduct of their
         respective businesses, except where any such failure to hold or comply
         will not have a material adverse effect on the Company and its
         Subsidiaries, taken as a whole.  The descriptions in the Registration
         Statement and the Prospectus of statutes, legal and governmental
         proceedings or contracts and other documents are accurate in all
         material respects and fairly present the information required to be
         shown; and there are no statutes or legal or governmental proceedings
         required to be described in the Registration Statement or the
         Prospectus that are not described as required.

         been duly  incorporated and is validly existing as a corporation in
         good standing under the laws of its jurisdiction of incorporation with
         full corporate power and authority to own or lease its properties and
         conduct its business as currently being carried on and as described in
         the Registration Statement and Prospectus; and is duly qualified to do
         business as a foreign corporation and is in good standing in each
         other jurisdiction in which it owns or leases real

         property of a nature, or transacts business of a type, that would make
         such qualification necessary and in which the failure to so qualify
         would have a material adverse effect on the financial condition,
         results of operations or business of the Company and the Subsidiaries,
         taken as a whole. Each of the Company and the Subsidiaries is in
         compliance with the rules, regulations or other lawful directives
         established by each regulatory authority having jurisdiction over the
         Company's or the Subsidiary's respective business, conduct and
         affairs, including without limitation the timely and accurate filing
         of all reports, statements, documents, registrations, filings or
         submissions required to be filed by it with any such regulatory
         authority, where the failure to comply with such rules, regulations or
         other lawful directives reasonably could or might be expected to
         result in a material adverse effect on the financial condition,
         results of operations or business of the Company and its Subsidiaries,
         taken as a whole.

                 (m)      Except as disclosed in the Registration Statement and
         the Prospectus, there is no action, suit, investigation or proceeding,
         governmental or otherwise, pending or overtly threatened, to which the
         Company or any Subsidiary is or may be a party or of which the
         business or property of the Company or any Subsidiary is or may be the
         subject which, in each case, is material to the Company and the
         Subsidiaries, taken as a whole, or which seeks to restrain, enjoin,
         prevent the consummation of or otherwise challenge the issuance of the
         Securities or any of the other transactions contemplated hereby or by
         the Indenture, or which questions the legality or validity of any such
         transactions or which seeks to recover damages or obtain other relief
         in connection with any of such transactions; and there is no contract
         or document of a character required to be described in the
         Registration Statement or the Prospectus or to be filed as an exhibit
         to the Registration Statement which is not described or filed as
         required.

                 (n)      All of the outstanding capital stock of each
         Subsidiary has been duly authorized, validly issued and is fully paid
         and non-assessable, and except as otherwise noted in the Prospectus,
         is owned directly or indirectly by the Company free and clear of any
         security interest, claim, lien or other encumbrance.

                 (o)      The Company and its Subsidiaries have good and
         marketable title in fee simple to all real property, if any, and good
         title to all personal property owned by them, in each case free and
         clear of all liens, security interests, pledges, charges,
         encumbrances, mortgages and defects, except such as are disclosed in
         the Prospectus or such as do not materially and adversely affect the
         value of those properties which individually or in the aggregate are
         material to the Company and its Subsidiaries taken as a whole and do
         notinterfere with the use made or proposed to be made of such property
         by the Company or any one of its Subsidiaries, as the case may be; and
         any real property and buildings held under lease by the Company or any
         of its Subsidiaries are held under valid, subsisting and enforceable
         leases, with such exceptions as are disclosed in the Prospectus or are
         not material and do not interfere with the use made or proposed to be
         made of such property and buildings by the Company or such Subsidiary.

                 (p)      The Company and each of its Subsidiaries have filed
         all necessary foreign, federal, state and local income and franchise
         tax returns and, other than taxes the Company or its Subsidiaries are
         contesting in good faith and for which the Company has established
         adequate reserves, have paid all taxes shown as due thereon.  Except
         as is otherwise expressly stated in the Registration Statement or
         Prospectus, the Company has no knowledge of any tax deficiency which
         might be asserted against it which would materially and adversely
         affect the financial condition, results of operations or business of
         the Company and its Subsidiaries, taken as a whole.

                 (q) Since the date of the most recent audited financial
         statements included or incorporated by reference in the Prospectus,
         neither the Company nor any of the Subsidiaries has sustained any loss
         or interference with its business, which loss or interference was
         material to the Company and its Subsidiaries, taken as a whole, 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, other than as disclosed in or contemplated by the
         Prospectus.

                 (r) Since the respective dates as of which information is
         given in the Registration Statement and the Prospectus, (i) neither
         the Company nor any of the Subsidiaries has incurred any liabilities
         or obligations, direct or contingent, or entered into any

         capital stock (except as a result of shares issued upon exercise of
         stock options pursuant to existing stock option plans of the Company
         and the Subsidiaries and upon conversion of the Company's 8%
         Convertible Subordinated Debentures), long-term debt or, otherwise
         than in the ordinary course of business consistent with past practice,
         short-term debt of the Company or any of the Subsidiaries and (iv)
         there has not been any material adverse change, or any development
         involving a prospective material adverse change, in or affecting the
         financial condition, results of operations or business of the Company
         and the Subsidiaries taken as a whole, in each case other than as
         disclosed in or contemplated by the Prospectus.

                 (s) Neither the Company nor any of its officers, directors or
         affiliates has taken, directly or indirectly, any action designed to
         cause or result in, or that has constituted or might reasonably be

         of any security of the Company to facilitate the sale of the Notes.

                 (t) Neither the Company nor any of the Subsidiaries, nor any

         and its Subsidiaries with respect to any real property currently
         leased or owned or by any means controlled by the Company or any

         state and local laws, ordinances, rules and regulations relating to
         occupational health and safety and the environment (collectively
         "Laws"), except where the failure to so comply would not have a
         material adverse effect on the Company's business or results of
         operations, and the Company and its Subsidiaries have all licenses,
         permits and authorizations necessary to operate under all Laws and are
         in compliance with all terms and conditions of such licenses, permits
         and authorizations, except where such failure would not have a
         material adverse effect on the Company's and its Subsidiaries'
         business or results of operations taken as a whole; neither the
         Company nor any Subsidiary has authorized, conducted or has knowledge
         of the generation, transportation, storage, use, treatment, disposal
         or release of any hazardous substance, hazardous waste, hazardous
         material, hazardous constituent, toxic substance, pollutant,
         contaminate, petroleum product, natural gas, liquefied gas or
         synthetic gas defined in or regulated under any environmental law on,

         pending or threatened claim, litigation or any administrative agency
         proceeding, nor has the Company or any Subsidiary received any written

         alleges the Company or any Subsidiary is a liable party under the
         Comprehensive Environmental Response, Compensation, and Liability Act,
         42 U.S.C. Section 9601 et seq. or any state superfund law; (iii)
         alleges possible contamination of the environment by the Company or
         any Subsidiary or (iv) alleges possible contamination of the Real
         Property, except as to each of the above, for any violations,
         liability or contamination that would not have a material adverse
         effect on the Company's and its Subsidiaries' business or results of
         operations taken as a whole.

         conduct; to the Company's knowledge, neither the Company nor any
         Subsidiary has infringed or is infringing, and neither the Company nor
         any Subsidiary has received notice of infringement with respect to,

         insurers of recognized financial responsibility against such losses
         and risks and in such amounts as are prudent and customary in the
         business in which they are engaged by similarly situated companies;
         and neither the Company nor any such Subsidiary has any reason to
         believe that it will not be able to renew its existing insurance
         coverage as and when such coverage expires or to obtain similar
         coverage from similar insurers as may be necessary to continue its
         business at a comparable cost, except as disclosed in the Prospectus.

                 (x) Each of the Company and its Subsidiaries makes and keeps
         accurate books, records and accounts, which, in reasonable detail,
         accurately and fairly reflect the transactions and dispositions of its
         assets and maintains a system of internal accounting controls
         sufficient to provide reasonable assurance that (i) transactions are
         executed in accordance with management's general and specific
         authorization, (ii) transactions are recorded as necessary to permit
         preparation of the Company's consolidated financial statements in

         Company or any other Subsidiary, except as disclosed in the
         Prospectus.

                 (z) The Company is not, will not become as a result of the
         transactions contemplated hereby, and does not intend to conduct its
         business in any manner that would cause it to become an "investment
         company" or a company "controlled" by an "investment company" within
         the meaning of the Investment Company Act of 1940.

                 (aa) The Company's common stock, par value $0.05 per share
         (the "Common Stock") is registered pursuant to Section 12(g) of the
         Exchange Act and is qualified as a Nasdaq National Market security of

         qualification of the Common Stock on the Nasdaq National Market, nor
         has the Company received any notification that the Commission or The
         Nasdaq Stock Market, Inc. is contemplating terminating such
         registration or qualification.

                 (bb) The Company has not distributed and will not distribute
         any prospectus or other offering material in connection with the

         to be

         the "road show" with the express approval of the Underwriters but not
         otherwise delivered to prospective purchasers of the Notes shall not
         be deemed, for the purposes of this paragraph 2(y), to be distributed
         by the Company.

                 (cc) The Company is in compliance with all provisions of
         Florida Statutes Section 517.075 (Chapter 92-198, laws of Florida).

         indirectly, with the government of Cuba or, to the Company's
         knowledge, with any person or entity located in Cuba.

                 (dd) The conditions for use of a Registration Statement on
         Form S-3 set forth in the General Instructions to Form S-3 have been
         satisfied with respect to the Company and the transactions
         contemplated by this Agreement and the Registration Statement.

                 (ee)     Any certificate signed by any officer of the Company
         and delivered to the Underwriters or to counsel for the Underwriters
         shall be deemed a representation and warranty by the Company to each
         Underwriter as to the matters covered thereby.

                 (ff)     Other than as contemplated herein, the Company has
         not incurred any liability for any finder's or broker's fee or agent's
         commission in connection with the execution and delivery of this
         Agreement or the consummation of the transactions contemplated hereby.

                 (a)      On the basis of the representations, warranties and
         agreements herein contained, but subject to the terms and conditions
         herein set forth, the Company agrees to issue and sell the Notes to
         the Underwriters, and the Underwriters agree to purchase the
         respective principal amounts of Notes set forth opposite each
         Underwriter's name in Schedule I hereto.  The purchase price for each
         Note shall be 97.0% of the principal amount thereof, which shall
         reflect an Underwriting Discount of 3.0% of the principal amount of
         the Notes payable to the Underwriters.  The obligation of each
         Underwriter to the Company shall be to purchase from the Company that
         principal amount of Notes set forth opposite the name of such
         Underwriter in Schedule I hereof.  In making this Agreement, each
         Underwriter is contracting severally and not jointly.  Except as
         provided in paragraph (b) of this Section 3 and in Section 8 hereof,
         the agreement of each Underwriter is to purchase only its respective
         principal amount of Notes as specified in Schedule I.

                 The Notes will be delivered by the Company to Piper Jaffray
         Inc. for each Underwriter's account against payment of the purchase
         price therefor by wire transfer of same day funds to the account

         fourth) full business day following the date hereof, or at such other
         time and date as the Underwriters and the Company determine pursuant
         to Rule 15c6-1(a) promulgated pursuant to the Exchange Act, such time
         and date of delivery being herein referred to as the "Closing Date."
         Delivery of the Notes shall be made by credit through full fast
         transfer to the accounts at The Depository Trust Company designated by
         Piper Jaffray Inc.

                 (b)      It is understood that each Underwriter may (but shall
         not be obligated to) make payment to the Company on behalf of another
         Underwriter for the Securities to be purchased by such Underwriter.
         Nothing herein contained shall constitute any of the Underwriters an
         unincorporated association or partner with the Company or with each
         other.

                 (c)      The Underwriters propose to make a public offering of
         the Notes directly to the public (which may include selected dealers
         and special purchasers) as soon as the Underwriters deem practicable
         after the Registration Statement becomes effective, at the initial
         public offering price as set forth on the cover page of the
         Prospectus, subject to the terms and conditions of this Agreement and
         in accordance with the Prospectus.  Such concessions from the public
         offering price may be allowed to selected dealers and other members of
         the National Association of Securities Dealers, Inc. as the
         Underwriters may determine, and the Underwriters will furnish the
         Company with such information about the distribution arrangements as
         may be necessary for inclusion in the Registration Statement.  It is
         understood that the public offering price and concessions may vary
         after the initial public offering.

         4.      Covenants.  The Company covenants and agrees with the
                 Underwriters as follows:

                 (a)      The Company will use its best efforts to cause any
         post-effective amendments to the Registration Statement to become
         effective as promptly as possible; the Company will notify the
         Underwriters promptly of the time when any post-effective amendment to
         the Registration Statement has become effective or any supplement to
         the Prospectus (including any term sheet with the meaning of Rule 434
         of the Rules and Regulations) has been filed and of any request by the
         Commission for any amendment or supplement to the Registration
         Statement or Prospectus or for additional information.  If the Company
         has elected to rely on Rule 430A of the Rules and Regulations, the
         Company will prepare and file a Prospectus (or term sheet within the
         meaning of Rule 434 of the Rules and Regulations) containing the
         information omitted therefrom pursuant to Rule 430A of the Rules and
         Regulations with the Commission within the time period required by,
         and otherwise in accordance with the provisions of, Rules 424(b), 430A
         and 434, if applicable, of the Rules and Regulations.  The Company
         will prepare and file with the Commission, promptly upon the request
         of any Underwriter, any amendments or supplements to the Registration
         Statement or Prospectus (including any term sheet within the meaning
         of Rule 434 of the Rules and Regulations) that, in the reasonable
         opinion of such Underwriter, may be necessary or advisable in
         connection with the distribution of the Securities by the
         Underwriters; and the Company will not file, at any time from the date
         hereof to the Closing Date, any amendment or supplement to the
         Registration Statement or Prospectus (including any term sheet within
         the meaning of Rule





                                       12
<PAGE>   13
         434 of the Rules and Regulations) or any document incorporated by
         reference therein (other than any supplement to the Prospectus
         relating solely to Other Securities) to which any Underwriter shall
         reasonably object by notice to the Company after having been furnished
         a copy a reasonable time prior to the filing.

                 (b)      The Company will advise the Underwriters, promptly
         after it shall receive notice or obtain knowledge thereof, of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement, of the suspension of the
         qualification of the Securities for offering or sale in any
         jurisdiction, or of the initiation or threatening of any proceeding
         for any such purpose; and the Company will promptly use its best
         efforts to prevent the issuance of any stop order or to obtain its
         withdrawal if such a stop order should be issued.

                 (c)  Within the time during which a prospectus (including any
         term sheet within the meaning of Rule 434 of the Rules and
         Regulations) relating to the Securities is required to be delivered
         under the Act, the Company will comply as far as it is able with all
         requirements imposed upon it by the Act, as now and hereafter amended,
         and by the Rules and Regulations, as from time to time in force, so
         far as necessary to permit the continuance of sales of or dealings in
         the Securities as contemplated by the provisions hereof and the
         Prospectus.  If during such period any event occurs as a result of
         which the Prospectus would include an untrue statement of a material
         fact or omit to state a material fact necessary to make the statements
         therein, in the light of the circumstances then existing, not
         misleading, or if during such period it is necessary to amend the
         Registration Statement or supplement the Prospectus to comply with the
         Act, the Company will promptly notify the Underwriters and will amend
         the Registration Statement or supplement the Prospectus (at the
         expense of the Company) so as to correct such statement or omission or
         effect such compliance.

                 (d)      The Company will use its best efforts to qualify the
         Securities for sale under the securities laws of such jurisdictions as
         the Underwriters may reasonably designate and to continue such
         qualifications in effect so long as required for the distribution of
         the Securities, except that the Company shall not be required in
         connection therewith to qualify as a foreign corporation or to execute
         a general consent to service of process in any state.  In each
         jurisdiction in which the Notes shall have been qualified as above
         provided, the Company will make and file such statements and reports
         as may be identified as requiring post-sale filings in any blue sky
         memoranda delivered in connection with the offer and sale of the Notes
         contemplated hereby or as otherwise reasonably requested by the
         Underwriters or officials of such jurisdictions.

                 (e)   The Company will furnish to you copies of the
         Registration Statement (two of which will be manually signed and will
         include all exhibits), the Indenture, each Preliminary Prospectus, the
         Prospectus, and all amendments and supplements (including any term
         sheet within the meaning of Rule 434 of the Rules and Regulations) to
         such documents, in each case as soon as available and in such
         quantities as each Underwriter may from time to time reasonably
         request.





                                       13
<PAGE>   14
                 (f)      So long as any Securities remain outstanding, the
         Company will file promptly all reports and any definitive proxy or
         information statements required to be filed by the Company with the
         Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
         Exchange Act and furnish to the Underwriters copies of all such
         reports and any definitive proxy or information statements, all
         communications with the stockholders of the Company and all
         information, documents and reports filed with the National Association
         of Securities Dealers, Inc., Nasdaq or any securities exchange.

                 (g)      The Company will make generally available to its
         security holders as soon as practicable, but in any event not later
         than 15 months after the end of the Company's current fiscal quarter,
         an earnings statement (which need not be audited) covering a 12-month
         period beginning after the effective date of the Registration
         Statement that shall satisfy the provisions of Section 11(a) of the
         Act and Rule 158 of the Rules and Regulations.

                 (h)      The Company, whether or not the transactions
         contemplated hereunder are consummated or this Agreement is prevented
         from becoming effective under the provisions of Section 9(a) hereof or
         is terminated, will pay or cause to be paid (i) all expenses
         (including transfer taxes allocated to the respective transferees)
         incurred in connection with the delivery to the Underwriters of the
         Securities, (ii) all expenses and fees (including, without limitation,
         fees and expenses of the Company's accountants and counsel but, except
         as otherwise provided below, not including fees and expenses of the
         Underwriters' counsel) in connection with the preparation, printing,
         filing, delivery, and shipping of the Registration Statement
         (including the financial statements therein and all amendments,
         schedules and exhibits thereto), the Securities, the Indenture, each
         Preliminary Prospectus, the Prospectus, and any amendment thereof or
         supplement thereto, and underwriting documents, including Blue Sky
         Memoranda, (iii) all filing fees and reasonable fees and disbursements
         of the Underwriters' counsel incurred in connection with the
         qualification of the Securities for offering and sale by the
         Underwriters or by dealers under the securities or blue sky laws of
         the states and other jurisdictions which the Underwriters shall
         designate in accordance with Section 4(d) hereof, (iv) the fees and
         expenses of the Trustee and counsel for the Trustee, (v) the filing
         fees incident to any required review by the National Association of
         Securities Dealers, Inc. of the terms of the sale of the Securities,
         (vi) listing fees, if any, (vii) fees or expenses, if any, of
         Underwriters' counsel incurred in connection with investigating the
         legality of an investment in the Securities by certain purchasers in
         certain jurisdictions and the preparation of memoranda relating
         thereto, (viii) any fees charged by security rating services for
         rating the Notes, and (ix) all other reasonable costs and expenses
         incident to the performance of its obligations hereunder that are not
         otherwise specifically provided for herein.  If the sale of the
         Securities provided for herein is not consummated by reason of action
         by the Company pursuant to Section 9(a) hereof which prevents this
         Agreement from becoming effective, or by reason of any failure,
         refusal or inability on the part of the Company to perform any
         material agreement on its part to be performed, or because any other
         material condition of the Underwriters' obligations hereunder required
         to be fulfilled by the Company is not fulfilled, the Company will
         reimburse the several Underwriters for all reasonable out-of-pocket
         disbursements (including fees and disbursements of counsel)





                                       14
<PAGE>   15
         incurred by the Underwriters in connection with their investigation,
         preparing to market and marketing the Securities or in contemplation
         of performing their obligations hereunder.  The Company shall not in
         any event be liable to any of the Underwriters for loss of anticipated
         profits from the transactions covered by this Agreement.

                 (i)      The Company will apply the net proceeds from the sale
         of the Securities to be sold by it hereunder for the purposes set
         forth in the Prospectus.

                 (j)      The Company has not taken and will not take, directly
         or indirectly, any action designed to or which might reasonably be
         expected to cause or result in, or which has constituted, the
         stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Securities.

                 (k)      For so long as the delivery of a prospectus is
         required in connection with the offering, sale and distribution of the
         Notes, the Company will file on a timely basis such registration
         statements and other filings and take such other action as is required
         pursuant to the Securities Exchange Act of 1934 and the rules and
         regulations promulgated thereunder.

                 (l)      So long as any of the Notes are outstanding, the
         Company will furnish to each of you, upon request, the reports
         required to be filed with the Trustee pursuant to the Indenture,
         concurrently with such filing.

                 (m)      The Company will use its best efforts to cause the
         Notes to be listed on the New York Stock Exchange, Inc. upon issuance
         of the Notes and will use its best efforts to cause the Notes to be so
         listed as long as the Notes remain outstanding.

                 (n)      The Company will inform the Florida Department of
         Banking and Finance at any time prior to the consummation of the
         distribution of the Securities by the Underwriters if it commences
         engaging in business with the government of Cuba or with any person or
         affiliate located in Cuba.  Such information will be provided within
         90 days after the commencement thereof or after a change occurs with
         respect to previously reported information.

         5.      Conditions of Underwriters' Obligations.  The obligations of
the several Underwriters hereunder are subject to the accuracy, as of the date
hereof and at the Closing Date (as if made at the Closing Date), of and
compliance with all representations, warranties and agreements of the Company
contained herein, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

                 (a)      The Registration Statement shall have become
         effective not later than 5:00 p.m., Minneapolis time, on the date of
         this Agreement, or at such later time and date as the Underwriters
         shall approve and all filings required by Rules 424, 430A and 434 of
         the Rules and Regulations shall have been timely made; no stop order
         suspending the effectiveness of





                                       15
<PAGE>   16
         the Registration Statement or any amendment thereof shall have been
         issued; no proceedings for the issuance of such an order shall have
         been initiated or threatened; and any request of the Commission for
         additional information (to be included in the Registration Statement
         or the Prospectus or otherwise) shall have been complied with to the
         Underwriters' satisfaction.

                 (b)      No Underwriter shall have advised the Company that
         the Registration Statement or the Prospectus, or any amendment thereof
         or supplement thereto (including any term sheet within the meaning of
         Rule 434 of the Rules and Regulations), contains an untrue statement
         of fact which in the reasonable opinion of any Underwriter, is
         material, or omits to state a fact which, in the reasonable opinion of
         any Underwriter, is material and is required to be stated therein or
         necessary to make the statements therein not misleading.

                 (c)      Except as contemplated in the Registration Statement
         and the Prospectus, and except for the issuance of any of the Other
         Securities, subsequent to the dates as of which information is given
         in the Prospectus, neither the Company nor any Subsidiary shall have
         incurred any material liabilities or obligations, direct or
         contingent, or entered into any material transactions not in the
         ordinary course of business, or declared or paid any dividends or made
         any distribution of any kind with respect to its capital stock; and
         there shall not have been any change in the capital stock (other than
         capital stock issued upon exercise of outstanding stock options or
         upon conversion of convertible debentures), or any material change in
         the short-term or long-term debt of the Company, or any issuance of
         options, warrants, convertible securities or other rights to purchase
         the capital stock of the Company or any Subsidiary, or any material
         adverse change, or any development involving a prospective material
         adverse change, in the general affairs, condition (financial or
         otherwise), business, key personnel, property, prospects, net worth or
         results of operations of the Company and the Subsidiaries, considered
         as a whole, that, in your judgment, makes it impractical or
         inadvisable to offer or deliver the Securities on the terms and in the
         manner contemplated in the Prospectus.

                 (d)      On the Closing Date, there shall have been furnished
         to the Underwriters, the opinion of Haynes and Boone, L.L.P., counsel
         for the Company, dated the Closing Date and addressed to the
         Underwriters, to the effect that:

                          (i)     The Company has all requisite corporate power
                 to execute, deliver and perform this Agreement.  This
                 Agreement has been duly authorized by all requisite corporate
                 action necessary on behalf of the Company, duly executed and
                 delivered by the Company and is enforceable against the
                 Company, subject to the General Qualifications.

                          (ii)    The Company has all requisite corporate power
                 to execute, deliver and perform its obligations under the
                 Indenture.  The Indenture has been duly authorized by all
                 requisite corporate action necessary on behalf of the Company,
                 has been duly executed and delivered by the Company and is
                 enforceable against the Company, subject to the General
                 Qualifications. The Notes being delivered on the





                                       16
<PAGE>   17
                 Closing Date have been duly authorized, and, when executed,
                 authenticated, issued and delivered in accordance with the
                 terms of the Indenture, will be enforceable against the
                 Company, subject to the General Qualifications.  The
                 Indenture and the form of Certificate representing the Notes
                 conform in all material respects, as to legal matters, to the
                 descriptions thereof contained in the Registration Statement
                 and the Prospectus.  The Indenture complies in all material
                 respects with the Trust Indenture Act.  The Notes have been
                 listed for trading on the New York Stock Exchange, Inc.

                          (iii) The execution and delivery by the Company of,
                 and performance of its obligations in, this Agreement, the
                 Indenture and the Notes being delivered on the Closing Date do
                 not (a) violate the Company's or any Material Subsidiary's
                 Constituent Documents, (b) breach, or result in a default
                 under, any existing obligation of the Company (or, as
                 applicable, the Material Subsidiaries) under the written
                 contracts listed on an exhibit to such opinion, or (c) violate
                 applicable provisions of statutory law or regulation.  Except
                 for permits and similar authorizations required under the Act,
                 the Trust Indenture Act and the securities or Blue Sky laws of
                 certain jurisdictions and except for permits and
                 authorizations which have been obtained and registrations
                 which have been effected, no consent, approval, authorization,
                 registration or order of, or filing with, any court or
                 governmental agency or body is required in connection with the
                 sale of the Notes by the Company.

                          (iv)    The Company's authorized, issued and
                 outstanding capital stock is as disclosed in the Prospectus.
                 All of the issued shares of capital stock of the Company have
                 been duly authorized and validly issued and are fully paid and
                 non-assessable.  To such counsel's Actual Knowledge, except as
                 disclosed in the Prospectus, there are no contracts,
                 agreements or understandings between the Company and any
                 person granting such person the right to require the Company
                 to file a registration statement under the Act with respect to
                 any securities of the Company owned or to be owned by such
                 person or to require the Company to include such securities in
                 the Registration Statement for the Notes (or any such right
                 has been effectively waived) and to such counsel's Actual
                 Knowledge, none of the issued shares of capital stock of the
                 Company, its predecessors or any Material Subsidiary has been
                 issued in violation of any preemptive rights of shareholders,
                 and no person or entity, including any holder of outstanding
                 shares of capital stock of the Company has any preemptive or,
                 to such counsel's Actual Knowledge, other similar rights to
                 subscribe for any of the Notes.  All of the shares of capital
                 stock of each Material Subsidiary have been duly authorized
                 and validly issued, are fully paid and non-assessable, and to
                 such counsel's Actual Knowledge are owned of record by the
                 Company and the Company has not received notice of any adverse
                 claim, except for security interests in the capital stock of a
                 majority of the Material Subsidiaries granted by the Company
                 pursuant to the First Amended and Restated Revolving Loan
                 Agreement dated as of April 25, 1996, as amended, among the

                          (v)     To such counsel's Actual Knowledge, the
                 Company is not named as a party to any pending or overtly
                 threatened litigation, arbitration, claim or proceeding that
                 is material to the Company and its Subsidiaries taken as a
                 whole, except as disclosed on the Company's Defensive
                 Litigation/Counterclaim Report for the Second Quarter 1996,
                 and all attachments thereto.  The statements contained in the
                 Prospectus under the captions "Management's Discussion and
                 Analysis of Financial Condition and Results of Operations --
                 Liquidity and Capital Resources," "Description of Securities,"
                 "Description of the Notes" and "Description of Other
                 Indebtedness," insofar as they purport to summarize the
                 provisions of statutes, legal and governmental proceedings or
                 contracts or other documents are materially accurate and
                 fairly present in all material respects the information
                 required to be shown.

                          (vi)    The Registration Statement is effective under
                 the Act and the Indenture has been qualified under the Trust
                 Indenture Act.  Any required filing of the Prospectus pursuant
                 to Rule 424(b) of the Rules and Regulations has been made in
                 the manner and within the time period required by such Rule.
                 To such counsel's Actual Knowledge, no stop order suspending
                 the effectiveness of the Registration Statement has been
                 issued and no proceeding for that purpose has been instituted
                 or threatened by the Commission.

                          (vii)  Each of the Company and the Material
                 Subsidiaries has been duly incorporated and is existing as a
                 corporation in good standing under the laws of its
                 jurisdiction of incorporation with full corporate power to own
                 or lease  its properties and conduct its business as described
                 in the Registration Statement and Prospectus.

                          (viii)  The Registration Statement and the Prospectus
                 (including the documents incorporated by reference therein)
                 and each amendment  or supplement thereto (other than the
                 financial statements and related schedules therein and other
                 than the Form T-1, as to each of which such counsel need
                 express no opinion), as of their respective effective or issue
                 dates, complied as to form in all material respects with the
                 requirements of the Act, the Rules and Regulations, the
                 Exchange Act and the rules and regulations promulgated
                 thereunder.

                          (ix) The Company is not, and immediately after the
                 Closing Date will not be, required to be registered under the
                 Investment Company Act of 1940, as amended, as an "investment
                 company," and, to the Actual Knowledge of such counsel, is not
                 a company "controlled" by an "investment company," within the
                 meaning of the Investment Company Act of 1940, as amended.

                 Such counsel shall also advise the Underwriters that although
         they do not assume any responsibility for, and cannot guarantee the
         accuracy, completeness or fairness of, the statements contained in the
         Registration Statement or the Prospectus, on the basis of the
         information such counsel developed during the course of preparing the
         Registration





                                       18
<PAGE>   19
         Statement and the Prospectus, which involved attending conferences
         with officers of the Company, the Company's accountants and other
         parties and a review of documents specifically referred to or
         incorporated by reference in the Registration Statement and Prospectus
         (although such documents incorporated by reference were prepared and
         filed by the Company without, in certain cases, such counsel's
         participation), and as a result of such counsel's participation in
         such conferences and review of such documents, but otherwise without
         independent check or verification except as specified, such counsel
         has no reason to believe that the Registration Statement, at the time
         the Registration Statement became effective, or any further amendment
         thereto upon filing thereof (but excluding the financial statements
         and supporting schedules  and other financial or statistical
         information or other scheduled data included or incorporated by
         reference therein and the Form T-1, as to each of which such counsel
         need express no comment), 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 further amendment or supplement thereto (but
         excluding the financial statements and supporting schedules and other
         financial or statistical information or other scheduled data included
         or incorporated by reference therein and the Form T-1, as to each of
         which such counsel need express no comment) contained or contains an
         untrue statement of a material fact or omits or omitted to state a
         material fact necessary to make the statements therein, in the light
         of the circumstances in which they were made, not misleading.

                 (e)      On the Closing Date, there shall have been furnished
         to the Underwriters, the opinion of L.  Keith Blackwell, Esq., General
         Counsel for the Company, dated the Closing Date and addressed to the
         Underwriters, to the effect that

                          (i)  the Company is duly qualified to transact
                 business as a foreign corporation and in good standing under
                 the laws of each other jurisdiction in which it owns or leases
                 material property, or conducts material business, so as to
                 require such qualification, except where the failure to so
                 qualify would not have a material adverse effect on the
                 financial position of the Company and its Subsidiaries, taken
                 as a whole.

                          (ii)  Each of the United States and foreign
                 Subsidiaries of the Company is duly qualified to transact
                 business as a foreign corporation and is in good standing
                 under the laws of each other United States and foreign
                 jurisdiction in which it owns or leases material property, or
                 conducts material business, so as to require such
                 qualification, except where the failure to so qualify would
                 not have a material adverse effect on the financial position
                 of the Company and its Subsidiaries, taken as a whole.

                          (iii) Each sale of the Company's capital stock, its
                 8% Convertible Subordinated Debentures due 2005 or its 10%
                 Senior Subordinated Notes due 2003 during the period from
                 December 13, 1992 through the Closing Date was, at the time





                                       19
<PAGE>   20
                 of each sale, registered or exempt from the registration
                 requirements of the Act and applicable state securities or
                 Blue Sky laws.

                          (iv)  To such counsel's Actual Knowledge, neither the
                 Company nor any of the Subsidiaries has (a) breached or
                 otherwise violated any existing obligation of the Company
                 under any court order that names the Company as a party or (b)
                 violated applicable provisions of statutory law or regulation,
                 in either case where any such breach or violation would have a
                 material adverse effect on the financial position of the
                 Company and its Subsidiaries, taken as a whole.

                          (v) To such counsel's Actual Knowledge, (a) the
                 Company has not violated its Certificate of Incorporation or
                 Bylaws and (b) neither the Company nor any of the Material
                 Subsidiaries has breached or otherwise violated any existing
                 obligation under any material agreement to which the Company
                 or any Material Subsidiary is a party, in either case where
                 such breach or violation would have a material adverse effect
                 on the financial position of the Company and its Subsidiaries,
                 taken as a whole.

                          (vi)  Except as disclosed in the Registration
                 Statement and the Prospectus, such counsel knows of no action,
                 suit, investigation or proceeding, governmental or otherwise,
                 pending or overtly threatened against the Company or any
                 Subsidiary, or involving the business or properties of the
                 Company or any Subsidiary with respect to the issuance and
                 sale of the Securities pursuant to this Agreement and the
                 Indenture or which is required to be described in the
                 Registration Statement or Prospectus that is not disclosed as
                 required.   The agreements, contracts and exhibits and
                 amendments thereto filed by the Company under the Exchange Act
                 to date constitute all of the material contracts to which the
                 Company or any of its Subsidiaries is a party which could be,
                 but are not, breached or violated in connection with the
                 execution and delivery by the Company of, and performance of
                 its obligations in, this Agreement, the Indenture and the
                 Notes and the consummation of the transactions herein and
                 therein contemplated. Such counsel does not know of any
                 contracts or documents of a character required to be described
                 in the Registration Statement or the Prospectus or to be filed
                 as an exhibit to the Registration Statement which are not
                 described or filed as required.  The descriptions contained in
                 the Registration Statement and Prospectus of contracts and
                 other documents are accurate and fairly present the
                 information required to be shown.  The statements contained in
                 the Registration Statement or the Prospectus to the extent
                 such statements relate to matters of law, descriptions of
                 statutes, legal or governmental proceedings, regulatory
                 matters or other legal matters or conclusions of law, fairly
                 summarize such matters.

                 (f)      On the Closing Date, there shall have been furnished
         to the Underwriters, such opinion or opinions from Lindquist & Vennum
         P.L.L.P., counsel for the Underwriters, dated the Closing Date and
         addressed to the Underwriters, with respect to the formation of the
         Company, the validity of the Securities, the Registration Statement,
         the Prospectus and other related matters as the Underwriters
         reasonably may request, and such counsel shall





                                       20
<PAGE>   21
         have received such papers and information as they request to enable
         them to pass upon such matters.

                 (g)      On the Closing Date the Underwriters shall have
         received letters from Deloitte & Touche, LLP, dated the Closing Date
         and addressed to the Underwriters, confirming that they are
         independent public accountants within the meaning of the Act and are
         in compliance with the applicable requirements relating to the
         qualifications of accountants under Rule 2-01 of Regulation S-X of the
         Commission, and stating, as of the date of such letter (or, with
         respect to matters involving changes or developments since the
         respective dates as of which specified financial information is given
         in the Prospectus, as of a date not more than five days prior to the
         date of such letter), the conclusions and findings of said firm with
         respect to the financial information and other matters covered by its
         letter delivered to the Underwriters concurrently with the execution
         of this Agreement, and the effect of the letter so to be delivered on
         the Closing Date shall be to confirm the conclusions and findings set
         forth in such prior letter.

                 (h)      On the Closing Date, there shall have been furnished
         to the Underwriters a certificate, dated the Closing Date and
         addressed to the Underwriters, signed by the Chief Executive Officer
         and by the Chief Financial Officer of the Company, to the effect that:

                          (i)  The representations and warranties of the
                 Company in this Agreement are true and correct, in all
                 material respects, as if made at and as of the Closing Date,
                 and the Company has complied with all the agreements and
                 satisfied all the conditions on its part to be performed or
                 satisfied at or prior to the Closing Date;

                          (ii)  To the best of their knowledge, no stop order
                 or other order suspending the effectiveness of the
                 Registration Statement or any amendment thereof or the
                 qualification of the Securities for offering or sale has been
                 issued, and, to the best of their knowledge, no proceeding for
                 that purpose has been instituted or is contemplated by the
                 Commission or any state or regulatory body; and

                          (iii)  The signers of said certificate have carefully
                 examined the Registration Statement and the Prospectus, and
                 any amendments thereof or supplements thereto (including any
                 term sheet within the meaning of Rule 434 of the Rules and
                 Regulations), and (A) such documents contain all statements
                 and information required to be included therein, the
                 Registration Statement, or any amendment thereof, does not
                 contain any untrue statement of a material fact or omit to
                 state any material fact required to be stated therein or
                 necessary to make the statements therein not misleading, and
                 the Prospectus, as amended or supplemented, does not include
                 any untrue statement of material fact or omit to state a
                 material fact necessary to make the statements therein, in
                 light of the circumstances under which they were made, not
                 misleading, (B) since the effective date of the Registration
                 Statement, there has occurred no event required to be set
                 forth in an amended or supplemented prospectus which has not
                 been so set forth, (C) except as disclosed in the Prospectus,
                 subsequent to the respective dates as of which information is
                 given in the Registration Statement and the Prospectus,
                 neither the Company nor any Subsidiary has incurred any
                 material liabilities or obligations, direct or contingent, or
                 entered into any material transactions not in the ordinary
                 course of business, or declared or





                                       21

                 paid any dividends or made any distribution of any kind with
                 respect to its capital stock, and except as disclosed in the
                 Prospectus, there has not been any change in the capital
                 stock, or any material change in the short-term or long-term
                 debt, or any issuance of options, warrants, convertible
                 securities or other rights to purchase the capital stock of
                 the Company or any Subsidiary, or any material adverse change,
                 or any development involving a prospective material adverse
                 change, in the general affairs, condition (financial or
                 otherwise), business, key personnel, property, prospects, net
                 worth or results of operations of the Company and the
                 Subsidiaries, considered as a whole, and (D) except as stated
                 in the Registration Statement and the Prospectus, there is not
                 pending, or, to the knowledge of the Company, threatened or
                 contemplated, any action, suit or proceeding to which the
                 Company or any Subsidiary is a party before or by any court or
                 governmental agency, authority or body, or any arbitrator,
                 which might result in any material adverse change in the
                 condition (financial or otherwise), business, prospects or
                 results of operations of the Company and the Subsidiaries,
                 considered as a whole.

                 (i)      The Company shall have furnished to the Underwriters
         and their counsel such additional documents, certificates and evidence
         as the Underwriters or their counsel may have reasonably requested.

                 All such opinions, certificates, letters and other documents
         will be in compliance with the provisions hereof only if they are
         reasonably satisfactory in form and substance to the Underwriters and
         counsel for the Underwriters.  The Company will furnish the
         Underwriters with such conformed copies of such opinions,
         certificates, letters and other documents as the Underwriters shall
         reasonably request.

         6.      Indemnification and Contribution.

                 (a)      The Company agrees to indemnify and hold harmless
         each Underwriter against any losses, claims, damages or liabilities,
         joint or several, to which such Underwriter may become subject, under
         the Act or otherwise (including in settlement of any litigation if
         such settlement is effected with the written consent of the Company),
         insofar as such losses, claims, damages or liabilities (or actions in
         respect thereof) arise out of or are based upon an untrue statement or
         alleged untrue statement of a material fact contained in the
         Registration Statement or incorporated therein by reference, including
         the information deemed to be a part of the Registration Statement at
         the time of effectiveness pursuant to Rules 430A and 434(d) of the
         Rules and Regulations, if applicable, any Preliminary Prospectus, the
         Prospectus, or any amendment or supplement thereto (including any term
         sheet within the meaning of Rule 434 of the Rules and Regulations), or
         arise out of or are based upon the omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, and will
         reimburse each Underwriter for any legal or other expenses reasonably
         incurred by it in connection with investigating or defending against
         such loss, claim, damage, liability or action; provided, however, that
         the Company shall not be liable in any such case to the extent that
         any such loss, claim, damage, liability or action arises out of or is
         based upon an untrue statement or alleged untrue statement or omission
         or alleged omission made in the Registration Statement, any
         Preliminary Prospectus, the Prospectus, or any such amendment or
         supplement, in reliance upon and in conformity with written
         information furnished to the





                                       22
<PAGE>   23
         Company by the Underwriters specifically for use in the preparation
         thereof; provided further, however, that the Company shall not be
         liable to any Underwriter in respect of any untrue statement or
         alleged untrue statement contained in, or omission or alleged omission
         from, any Preliminary Prospectus to the extent that (i) the Prospectus
         did not contain such untrue statement or alleged untrue statement or
         omission or alleged omission giving rise to such loss, claim, damage,
         liability or action, (ii) the Prospectus was not sent or given to the
         purchaser of the Notes in question at or prior to the time at which
         the written confirmation of the sale of Notes was sent or given to
         such person, and (iii) the failure to deliver such Prospectus was not
         the result of the Company's non-compliance with its obligations under
         Section 4(e) hereof.

                 (b)      Each Underwriter will indemnify and hold harmless the
         Company against any losses, claims, damages or liabilities to which
         the Company may become subject, under the Act or otherwise (including
         in settlement of any litigation, if such settlement is effected with
         the written consent of such Underwriter), insofar as such losses,
         claims, damages or liabilities (or actions in respect thereof) arise
         out of or are based upon an untrue statement or alleged untrue
         statement of a material fact contained in the Registration Statement,
         any Preliminary Prospectus, the Prospectus, or any amendment or
         supplement thereto (including any term sheet within the meaning of
         Rule 434 of the Rules and Regulations), or arise out of or are based
         upon the omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, in each case to the extent, but only to the
         extent, that such untrue statement or alleged untrue statement or
         omission or alleged omission was made in the Registration Statement,
         any Preliminary Prospectus, the Prospectus, or any such amendment or
         supplement thereto, in reliance upon and in conformity with written
         information furnished to the Company by such Underwriter, specifically
         for use in the preparation thereof, and will reimburse the Company for
         any legal or other expenses reasonably incurred by the Company in
         connection with investigating or defending against any such loss,
         claim, damage, liability or action.

                 (c)      Promptly after receipt by an indemnified party under
         subsection (a) or (b) above of notice of the commencement of any
         action, such indemnified party shall, if a claim in respect thereof is
         to be made against the indemnifying party under such subsection,
         notify the indemnifying party in writing of the commencement thereof;
         but the omission so to notify the indemnifying party shall not relieve
         the indemnifying party from any liability that it may have to any
         indemnified party otherwise than under such subsection or unless and
         to the extent that the indemnifying party is substantially prejudiced
         thereby.  In case any such action shall be brought against any
         indemnified party, and it shall notify the indemnifying party of the
         commencement thereof, the indemnifying party shall be entitled to
         participate in, and, to the extent that it shall wish, jointly with
         any other indemnifying party similarly notified, to assume the defense
         thereof, with counsel satisfactory to such indemnified party, and
         after notice from the indemnifying party to such indemnified party of
         the indemnifying party's election so to assume the defense thereof,
         the indemnifying party shall not be liable to such indemnified party
         under such subsection for any legal or other expenses subsequently
         incurred by such indemnified party in connection with the defense
         thereof other than reasonable costs of investigation; provided,
         however, that if, in the sole judgment of the Underwriters, it is
         advisable for the Underwriters to be represented as a group by
         separate counsel, the Underwriters shall have the right to employ a
         single counsel to represent all Underwriters who may be subject to a
         liability arising from any claim in respect of which





                                       23
<PAGE>   24
         indemnity may be sought by the Underwriters under paragraph (a) of
         this Section 6, in which event the reasonable fees and expenses of
         such separate counsel shall be borne by the indemnifying party or
         parties and remitted to the Underwriters for payment to such counsel
         as such fees and expenses are incurred.  An indemnifying party shall
         not be obligated under any settlement agreement relating to any action
         under this Section 6 to which it has not agreed in writing.

                 (d)      If the indemnification provided for in this Section 6
         is unavailable or insufficient to hold harmless an indemnified party
         under subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as
         a result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above, (i) in such proportion as is appropriate
         to reflect the relative benefits received by the Company on the one
         hand and the Underwriters on the other from the offering of the
         Securities or (ii) if the allocation provided by clause (i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause (i)
         above but also the relative fault of the Company on the one hand and
         the Underwriters on the other in connection with the statements or
         omissions that resulted in such losses, claims, damages or
         liabilities, as well as any other relevant equitable considerations.
         The relative benefits received by the Company on the one hand and the
         Underwriters on the other shall be deemed to be in the same proportion
         as the total net proceeds from the offering (before deducting
         expenses) received by the Company bear to the total underwriting
         discounts and commissions received by the Underwriters, in each case
         as set forth in the table on the cover page of the Prospectus.  The
         relative fault shall be determined by reference to, among other
         things, whether the untrue or alleged untrue statement of a material
         fact or the omission or alleged omission to state a material fact
         relates to information supplied by the Company or the Underwriters and
         the parties' relevant intent, knowledge, access to information and
         opportunity to correct or prevent such untrue statement or omission.
         The Company and the Underwriters agree that it would not be just and
         equitable if contributions pursuant to this subsection (d) were to be
         determined by pro rata allocation (even if the Underwriters were
         treated as one entity for such purpose) or by any other method of
         allocation which does not take account of the equitable considerations
         referred to in the first sentence of this subsection (d).  The amount
         paid by an indemnified party as a result of the losses, claims,
         damages or liabilities referred to in the first sentence of this
         subsection (d) shall be deemed to include any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending against any action or claim which is the
         subject of this subsection (d).  Notwithstanding the provisions of
         this subsection (d), no Underwriter shall be required to contribute
         any amount in excess of the amount by which the total price at which
         the Securities underwritten by it and distributed to the public were
         offered to the public exceeds the amount of any damages that such
         Underwriter has otherwise been required to pay by reason of such
         untrue or alleged untrue statement or omission or alleged omission.
         No person guilty of fraudulent misrepresentation (within the meaning
         of Section 11(f) of the Act) shall be entitled to contribution from
         any person who was not guilty of such fraudulent misrepresentation.
         The Underwriters' obligations in this subsection (d) to contribute are
         several in proportion to their respective underwriting obligations and
         not joint.

                 (e)      The obligations of the Company under this Section 6
         shall be in addition to any liability which the Company may otherwise
         have and shall extend, upon the same terms





                                       24
<PAGE>   25
         and conditions, to each person, if any, who controls any Underwriter
         within the meaning of the Act; and the obligations of the Underwriters
         under this Section 6 shall be in addition to any liability that the
         respective Underwriters may otherwise have and shall extend, upon the
         same terms and conditions, to each director of the Company (including
         any person who, with his consent, is named in the Registration
         Statement as about to become a director of the Company), to each
         officer of the Company who has signed the Registration Statement and
         to each person, if any, who controls the Company within the meaning of
         the Act.

         7.      Representations and Agreements to Survive Delivery.  All
representations, warranties, and agreements of the Company herein or in
certificates delivered pursuant hereto, and the agreements of the several
Underwriters and the Company contained in Section 6 hereof, shall remain
operative and in full force and effect regardless of any investigation made by
or on behalf of any Underwriter or any controlling person thereof, or the
Company or any of its officers, directors, or controlling persons and shall
survive delivery of, and payment for, the Securities to and by the Underwriters
hereunder.

         8.      Substitution of Underwriters.

                 (a) If any Underwriter or Underwriters shall fail to take up
         and pay for the aggregate principal amount of Notes agreed by such
         Underwriter or Underwriters to be purchased hereunder, upon tender of
         such Notes in accordance with the terms hereof, and the principal
         amount of Notes not purchased does not in either case aggregate more
         than 10% of the aggregate principal amount of Notes set forth in
         Schedule I hereto, the remaining Underwriters shall be obligated,
         severally, in proportion to the respective principal amount of Notes
         which they are obligated to purchase hereunder, to take up and pay for
         the principal amount of Notes that the withdrawing or defaulting
         Underwriter or Underwriters agreed but failed to purchase.

                 (b)      If any Underwriter or Underwriters shall fail to take
         up and pay for the aggregate principal amount of Notes agreed by such
         Underwriter or Underwriters to be purchased hereunder, upon tender of
         such Notes in accordance with the terms hereof, and the principal
         amount of Notes not purchased aggregates more than 10% of the
         aggregate principal amount of Notes set forth in Schedule I hereto,
         and arrangements for the purchase of such Firm Notes by other persons
         reasonably satisfactory to the Company are not made within 36 hours
         thereafter, this Agreement shall terminate.  In the event of any such
         termination the Company shall not be under any liability to any
         Underwriter (except to the extent provided in Section 4(h) and Section
         6 hereof) nor shall any Underwriter (other than an Underwriter who
         shall have failed, otherwise than for some material reason permitted
         under this Agreement, to purchase the aggregate principal amount of
         Notes agreed by such Underwriter to be purchased hereunder) be under
         any liability to the Company (except to the extent provided in Section
         6 hereof).  Nothing contained herein shall relieve a defaulting
         Underwriter from liability for its default.

                 If Notes to which a default relates are to be purchased by
         non-defaulting Underwriters or by any other party or parties, the
         non-defaulting Underwriters or the Company shall have the right to
         postpone the Closing Date for not more than seven business days in
         order that the necessary changes in the Registration Statement,
         Prospectus and any other documents, as well as any other arrangements,
         may be effected.  As used herein, the





                                       25
<PAGE>   26
         term "Underwriter" includes any person substituted for an Underwriter
         under this Section 8.

         9.      Effective Date of this Agreement and Termination.

                 (a)      This Agreement shall become effective at 10:00 a.m.,
         Minneapolis time, on the first business day following the date hereof,
         or at such earlier time after the effective date of the Registration
         Statement as the Underwriters in their discretion shall first release
         the Securities for sale to the public.  For the purpose of this
         Section, the Securities shall be deemed to have been released for sale
         to the public upon release by the Underwriters of the publication of a
         newspaper advertisement relating thereto or upon release by the
         Underwriters of telexes offering the Securities for sale to securities
         dealers, whichever shall first occur.  By giving notice as hereinafter
         specified before the time this Agreement becomes effective, the
         Underwriters or the Company may prevent this Agreement from becoming
         effective without liability of any party to any other party, except
         that the provisions of Section 4(h) and Section 6 hereof shall at all
         times be effective.

                 (b)      The Underwriters shall have the right to terminate
         this Agreement by giving notice as hereinafter specified at any time
         at or prior to the Closing Date, if (i) the Company shall have failed,
         refused or been unable, at or prior to the Closing Date, to perform
         any agreement on its part to be performed hereunder, (ii) any other
         condition of the Underwriters' obligations hereunder is not fulfilled,
         (iii) trading on the New York Stock Exchange or the American Stock
         Exchange shall have been wholly suspended, (iv) minimum or maximum
         prices for trading shall have been fixed, or maximum ranges for prices
         for securities shall have been required, on the New York Stock
         Exchange or the American Stock Exchange, by such Exchange or by order
         of the Commission or any other governmental authority having
         jurisdiction, (v) a banking moratorium shall have been declared by
         Federal, New York, Texas or Minnesota authorities, or (vi) there has
         occurred any material adverse change in the financial markets in the
         United States or an outbreak of major hostilities (or an escalation
         thereof) in which the United States is involved, a declaration of war
         by Congress, any other substantial national or international calamity
         or any other event or occurrence of a similar character shall have
         occurred since the execution of this Agreement that, in the
         Underwriters' judgment, makes it impractical or inadvisable to proceed
         with the completion of the sale of and payment for the Securities.
         Any such termination shall be without liability of any party to any
         other party except that the provisions of Section 4(h) and Section 6
         hereof shall at all times be effective.

                 (c)      If the Underwriters elect to prevent this Agreement
         from becoming effective or to terminate this Agreement as provided in
         this Section, the Company shall be notified promptly by the
         Underwriters by telephone or telegram, confirmed by letter.  If the
         Company elects to prevent this Agreement from becoming effective, the
         Underwriters shall be notified by the Company by telephone or
         telegram, confirmed by letter.

         10.     Information Furnished by Underwriters. The statements set
forth in the last paragraph of the cover page and under the caption
"Underwriting" in any Preliminary Prospectus and in the Prospectus constitute
the written information furnished by or on behalf of the Underwriters referred
to in Section 2 and Section 6 hereof.

         For and in consideration of the premises and the purchase of the

SECTION 104.     Acts of Holders.

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

         Without limiting the generality of the foregoing, a Holder, including
a Depositary that is a Holder of a Global Security, may make, give or take, by
a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted hereby to be made, given or taken by the Holders, and a Depositary
that is a Holder of a Global Security may provide its proxy or proxies to the
beneficial owners of interests in any such Global Security through such
Depositary's standing instructions and customary practices.

         (b)     The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems





                                       11
<PAGE>   18
sufficient and in accordance with such reasonable rules as the Trustee may
determine, provided that, in any instance, the Trustee may require further
proof with respect to any matter referred to in this Section.

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

         (d)     The Company may fix any day as the record date for the purpose
of determining the Holders (including Persons who hold Securities through a
Holder which is a Depositary) of Securities of any series entitled to give or
take any request, demand, authorization, direction, notice, consent, waiver or
other action, or to vote on any action, authorized or permitted to be given or
taken by Holders of Securities of such series. If not set by the Company prior
to the first solicitation of a Holder of Securities of such series made by any
Person in respect of any such action, or, in the case of any such vote, prior
to such vote, the record date for any such action or vote shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 701) prior to such first solicitation or vote, as
the case may be.  With regard to any record date for action to be taken by the
Holders (including Persons who hold Securities through a Holder which is a
Depositary) of one or more series of Securities, only the Holders of Securities
of such series on such date (or their duly designated proxies) shall be
entitled to give or take, or vote on, the relevant action.

         With regard to any action that may be given or taken hereunder only by
Holders (including Persons who hold their Securities through a Holder which is
a Depositary) of a requisite principal amount of Outstanding Securities of any
series (or their duly appointed agents) and for which a record date is set
pursuant to this subsection (d), the Company may, at its option, set an
expiration date after which no such action purported to be given or taken by
any Holder shall be effective hereunder unless given or taken on or prior to
such expiration date by Holders (including Persons who hold Securities through
a Holder which is a Depositary) of the requisite principal amount of
Outstanding Securities of such series on such record date (or their duly
appointed agents).  On or prior to any expiration date set pursuant to this
subsection (d), the Company may, on one or more occasions at its option, extend
such date to any later date.  Nothing in this subsection (d) shall prevent any
Holder (or any duly appointed agent thereof, from giving or taking, after any
expiration date, any action identical to, or, at any time, contrary to or
different from any action given or taken, or purported to have been given and
taken, hereunder by a Holder on or prior to such date, in which event the
Company may set a record date in respect hereof pursuant to this subsection
(d).

         Notwithstanding the foregoing, upon receipt by the Trustee, with
respect to Securities of any series, of (i) any Notice of Default pursuant to
Section 501, (ii) any declaration or acceleration, or any rescission and
annulment of any such declaration, pursuant to Section 502, or (iii) any
direction given pursuant to Section 512 (any such notice, declaration,
rescission and annulment, or direction being referred to herein





                                       12
<PAGE>   19
as a "Direction"), a record date shall automatically and without any other
action by any Person be set for the purpose of determining the Holders
(including Persons who hold Securities through a Holder which is a Depositary)
of Outstanding Securities of such series entitled to join in such Direction,
which record date shall be the close of business on the day the Trustee
receives such Direction.  The Holders (including Persons who hold Securities
through a Holder which is a Depositary) of Outstanding Securities of such
series on such record date (or their duly appointed agents), and only such
Persons, shall be entitled to join in such Direction, whether or not such
Holders remain Holders after such record date; provided that, unless such
Direction shall have become effective by virtue of Holders (including Persons
who hold Securities through a Holder which is a Depositary) of the requisite
principal amount of Outstanding Securities of such series on such record date
(or their duly appointed agents) having joined therein on or prior to the 90th
day after such record date, such Direction shall automatically and without any
action by any Person be canceled and be of no further effect.  Nothing in this
paragraph shall prevent a Holder (or duly appointed agent thereof) from giving,
before or after the expiration of such 90-day period, a Direction contrary to
or different from, or, after the expiration of such period, identical to, a
Direction that has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date in respect thereof shall be set
pursuant to this subsection (d).

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

SECTION 105.     Notices, Etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted hereby 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 (unless otherwise herein
         expressly provided) if made, given, furnished or filed in writing to
         or with a Responsible Officer of the Trustee at its Corporate Trust
         Office, Attention: Corporate Trust Department, or

                 (2)      the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, or sent by facsimile and U.S. mail, 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
         (Attention: Chief Financial Officer) or at any other address
         previously furnished in writing to the Trustee by the Company.

SECTION 106.     Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder
(including Persons who hold Securities through a Holder which is a Depositary
if the name and address of such beneficial holder has been provided in writing
to the Person required to give such notice prior to the date such notice is
given) affected by such event, at such Holder's address as it appears in the
Security Register or as provided in writing by the Depositary, not later than
the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders.  Any notice mailed to the Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder three days after deposit with the U.S. Mail, whether or not such Holder
actually receives such notice.  Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

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

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted hereunder shall be in the English
language.

SECTION 107.     Compliance with Trust Indenture Act.

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

SECTION 108.     Effect of Headings and Table of Contents.

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

         All covenants and agreements herein by the Company or the Trustee

         In case any provision herein or in the Securities shall be invalid,
illegal or unenforceable, either wholly or partially, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby, and such provisions shall be given effect to the fullest
extent permitted by law.

SECTION 111.     Benefits of Indenture.

         Nothing herein or in the Securities, express or implied, shall give to
any Person, other than the parties hereto, any Authenticating Agent, any Paying
Agent, any Securities Registrar, and their successors hereunder and the Holders
(including Persons who hold Securities through a Holder which is a Depositary),
any benefit or any legal or equitable right, remedy or claim hereunder.

SECTION 112.     Governing Law.

         This Indenture and the Securities shall be governed by and construed
in accordance with the laws of the State of Texas.

SECTION 113.     Legal Holidays.

         Except as may be otherwise specified with respect to any particular
Securities, in any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision hereof or of the Securities)
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

         any Securities which, pursuant to Section 303, are deemed never to
         have been authenticated and delivered hereunder) and the absence of
         such limitation shall mean that the Company may issue from time to
         time additional securities of such series without limitation as to
         aggregate principal amount;

                 (3)      the Person to whom any interest on a Security of the
         series shall be payable, if other than the Person in whose name that

                 (5)      the rate or rates (which may be fixed or variable) at
         which the Securities of the series shall bear interest, if any, or the
         method by which such rate or rates shall be determined, the date or
         dates from which such interest shall accrue, the Interest Payment
         Dates on which such interest shall be payable, the Regular Record Date

         obligation;

                 (9)      whether the Securities of the series will be

         securities, and if so, the terms and conditions upon which such

         payment of the principal of and any premium and interest on Securities
         of such series as to which such election is made shall be payable, and

         respect to Securities of the series in addition to or in lieu of those
         provided in Section 501 and any change in the right of the Trustee or
         the Holders to declare the principal of or any premium or interest on
         such Securities due and payable;

                 (16)     if less than the principal amount thereof, the
         portion of the principal amount of Securities of the series which
         shall be payable upon declaration of acceleration of the Maturity
         thereof pursuant to Section 502;

                 (17)     whether the Securities of the series shall be issued

         forth in Section 305;

                 (18)     if applicable, that the Securities of the series, in

         any election by the Company to defease such Securities shall be
         evidenced; and

                 (19)     any other terms of the series (which terms shall not
         be inconsistent with the provisions hereof, except as permitted by
         Section 901(5)).

         All Securities of any one series (other than Securities offered in a
Periodic Offering) shall be substantially identical except as to denomination
and except as may otherwise be provided by or pursuant to the Board Resolution
referred to above and, subject to Section 303, set forth, or determined in the
manner provided, in the Officers' Certificate referred to above or in any such
indenture supplemental hereto.  All Securities of any one series need not be
issued at the same time.  Unless otherwise provided, Securities of a single
series may have different terms, and a series may be reopened, without the
consent of the Holders of Securities of such series, for issuance of additional
Securities of such series.

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





                                       19
<PAGE>   26
         With respect to Securities of a series offered in a Periodic Offering,
such Board Resolution and Officers' Certificate or supplemental indenture may
provide general terms or parameters for Securities of such series and provide
either that the specific terms of particular Securities of such series shall be
specified in a Company Order or that such terms shall be determined by the
Company or its agents in accordance with other procedures specified in a
Company Order as contemplated by the third paragraph of Section 303.

         SECTION 302.     Denominations.

         Unless otherwise provided in the applicable Officers' Certificate or
supplemental indenture, the Securities of each series shall be issued in
registered form without coupons in such denominations as shall be specified as
contemplated by Section 301.  In the absence of any such provisions with
respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 or any amount in excess thereof which is an
integral multiple of $1,000.

SECTION 303.     Execution, Authentication, Delivery and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, one of its Vice Chairman of the Board, its President,
its Chief Executive Officer, its Chief Operating Officer, its Chief Financial
Officer, its Treasurer or one of its Vice Presidents, and under its corporate
seal affixed thereto or reproduced thereon attested by its Secretary or one of
its Assistant Secretaries.  The signature of any of these officers on the
Securities may be manual or facsimile.

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

         At any time and from time to time after the execution and delivery
hereof, 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, or, in the case of
Securities offered in a Periodic Offering, from time to time in accordance with
such other procedures (including, without limitation, the receipt by the
Trustee of electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing by the Company) acceptable to the Trustee
as may be specified from time to time by a Company Order for establishing the
specific terms of particular Securities being so offered, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or forms or terms of the Securities of the series have
been established by or pursuant to one or more Board Resolutions as permitted
by Sections 201 and 301, in authenticating such Securities and accepting the
additional responsibilities hereunder in relation to such Securities, the
Trustee





                                       20
<PAGE>   27
shall be entitled to receive, and (subject to Section 601) shall be fully
protected in relying upon

         (a)     an Opinion of Counsel stating:

                 (1)      that the form or forms of such Securities have been
         established in conformity with the provisions hereof;

                 (2)      that the terms of such Securities have been
         established in conformity with the provisions hereof;

                 (3)      that authentication and delivery of such Securities
         and the execution and delivery of the supplemental indenture, if any,
         by the Trustee will not violate the terms hereof;

                 (4)      that the Company has the corporate power to issue,
         and has duly authorized, such Securities;

                 (5)      that such Securities, when authenticated and
         delivered by the Trustee and issued by the Company in the manner and
         subject to any conditions specified in such Opinion of Counsel, will
         constitute valid and legally binding obligations of the Company,
         enforceable against the Company in accordance with their terms,
         subject to bankruptcy, insolvency, reorganization, moratorium,
         fraudulent conveyance or transfer and other laws of general
         applicability relating to or affecting the enforcement of creditors'
         rights and to general equity principles, provided that such Opinion of
         Counsel need not express an opinion as to whether a court in the
         United States would render a money judgment in a currency other than
         that of the United States; and

                 (6)      that the issuance of such Securities will not
         contravene the certificate of incorporation or bylaws of the Company
         or result in any violation of any of the terms or provisions of any
         law or regulation or of any indenture, mortgage or other agreement
         known to such Counsel by which the Company or its assets is bound, the
         violation of which would have a material adverse effect on the Company
         and its subsidiaries taken as a whole;

         (b)     an executed supplemental indenture, if any;

         (c)     a copy of a Board Resolution; and

         (d)     an Officers' Certificate;

provided, however, that, with respect to Securities of a series offered in a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel in connection only with the first authentication of each form of
Securities of such series





                                       21
<PAGE>   28
and that the opinions described in clauses (a)(2) and (a)(5) above may state,
respectively, that

                 (2)      if the terms of such Securities are to be established
         pursuant to a Company Order or pursuant to such procedures as may be
         specified from time to time by a Company Order, all as contemplated by
         a Board Resolution or action taken pursuant thereto, such terms will
         have been duly authorized by the Company and established in conformity
         with the provisions hereof; and

                 (5)      that such Securities, when executed by the Company,
         completed, authenticated and delivered by the Trustee in accordance
         herewith, and issued and delivered by the Company and paid for, all in
         accordance with any agreement of the Company relating to the offering,
         issuance and sale of such Securities, will be duly issued hereunder
         and will constitute valid and legally binding obligations of the
         Company, enforceable in accordance with their terms, subject to
         bankruptcy, insolvency, reorganization, moratorium and other laws
         relating to or affecting generally the enforcement of creditors'
         rights and to general principles of equity.

         With respect to Securities of a series offered in a Periodic Offering,
the Trustee may rely conclusively, as to the authorization by the Company of
any of such Securities, the form or forms and terms thereof and the legality,
validity, binding effect and enforceability thereof, upon the Opinion of
Counsel, Company Order and other documents delivered pursuant to Sections 201
and 301 and this Section, as applicable, in connection with the first
authentication of a form of Securities of such series and it shall not be
necessary for the Company to deliver such Opinion of Counsel and other
documents (except as may be required by the specified other procedures, if any,
referred to above) at or prior to the time of authentication of each Security
of such series unless and until the Trustee receives actual notice that such
Opinion of Counsel or other documents have been superseded or revoked, and may
assume compliance with any conditions specified in such Opinion of Counsel
(other than any conditions to be performed by the Trustee).  If such form or
forms or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant hereto
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.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit hereunder or be valid or
obligatory for any purpose unless there appears on such Security a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence and the only evidence, that such Security has been duly
authenticated and delivered hereunder and is entitled to the benefits hereof.





                                       22
<PAGE>   29
         Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309, for all purposes hereof such Security shall be deemed
never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits hereof.

SECTION 304.     Temporary Securities.

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

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay.  After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable, subject to Section
305, for definitive Securities of like tenor of such series upon surrender of
the temporary Securities of such series at the office or agency of the Company
in a Place of Payment for that series, without charge to the Holder.  Upon
surrender for cancellation of any one or more temporary Securities of any
series the Company shall execute and the Trustee shall authenticate and deliver
in exchange therefor a like principal amount of definitive Securities of the
same series and of like tenor and of any authorized denominations.  Unless
otherwise provided in or pursuant hereto, until so exchanged the temporary
Securities of any series shall in all respects be entitled to the same benefits
hereunder as definitive Securities of such series and tenor.

SECTION 305.     Registration, Registration of Transfer and Exchange; Paying
Agent and Place of Payment.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" of each series of Securities for the
purpose of registering Securities and transfers of Securities as herein
provided at the Corporate Trust Office.

         Upon surrender for registration of transfer of any Security of any
series at the office or agency of the Company in any Place of Payment for such
series, the Company shall execute and the Trustee shall authenticate and
deliver (in the name of the designated transferee or transferees) one or more
new Securities of the same





                                       23
<PAGE>   30
series, of any authorized denominations and of a like aggregate principal
amount and tenor and bearing a number not contemporaneously outstanding.

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

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

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

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

         The Company may but shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 calendar days before the day of the mailing of a
notice of redemption of Securities of that series selected for redemption under
Section 1103 and ending at the close of business on the day of such mailing,
(ii) to register the transfer of or exchange any Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part, or (iii) to register the transfer of or exchange any
certificated Securities during a period beginning five days before the date of
Maturity with respect to such Security and ending on such date of Maturity.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, no Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the name of, and no transfer
of a Global Security of any series may be registered to, any Person other than
the Depositary for such Security or its nominee, unless (i) such Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for such Global Security or the Company determines that the Depositary is
unable to continue as Depositary and the Company





                                       24
<PAGE>   31
thereafter fails to appoint a successor Depositary, (ii) the Company provides
for such exchange or registration of transfer pursuant to Section 301, (iii)
the Company executes and delivers to the Trustee a Company Order that such
Global Security shall be so exchangeable and the transfer thereof so
registrable or (iv) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series which entitles the
Holders of such Securities to accelerate the maturity thereof.  Upon the
occurrence in respect of any Global Security of any series of any one or more
of the conditions specified in clauses (i), (ii), (iii) or (iv) of the
preceding sentence or such other conditions as may be specified as contemplated
by Section 301 for such series, such Global Security may be exchanged for
certificated Securities not bearing the legend specified in Section 203 and
registered in the names of such Persons as may be specified by the Depositary
(including Persons other than the Depositary or its nominees).

         Notwithstanding any other provision hereof, a Global Security may not
be transferred except as a whole by the Depositary for such Global Security to
a nominee of the Depositary or by a nominee of the Depositary to the Depositary
or another nominee of the Depositary.

         The Company shall maintain an office or agency where Securities of any
series may be presented for payment ("Paying Agent").  The Company may appoint
one or more additional paying agents.  The term "Paying Agent" includes any
additional paying agent.  The Company may change any Paying Agent without
notice to any Holder.  The Company shall notify the Trustee in writing of the
name and address of any Agent not a party to this Indenture.  If the Company
fails to appoint or maintain another entity as Paying Agent, the Trustee shall
act as such.  The Company or any of its Subsidiaries may act as Paying Agent.

         The Company initially appoints the Trustee to act as Paying Agent with
respect to the Securities.  The Corporate Trust Office of the Trustee shall
initially be deemed a Place of Payment.  The Company may designate in a Company
Order additional Places of Payment for Securities of any series.

         The Company shall require each Paying Agent, including the Trustee
(who shall be deemed to have agreed by its execution of this Indenture), to
agree in writing that the Paying Agent shall hold in trust for the benefit of
Holders or the Trustee (unless the Paying Agent is the Trustee, in which case
it shall hold in trust for the Holders) all money held by the Paying Agent for
the payment of principal, premium, if any, or interest, on the Securities, and
shall notify the Trustee of any default by the Company in making any such
payment.  While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee.  The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee.  Upon
payment over to the Trustee, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money.  If the Company or a
Subsidiary acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying





                                       25
<PAGE>   32
Agent.  Upon any bankruptcy or reorganization proceedings relating to the
Company, the Trustee shall serve as sole Paying Agent for the Securities.

SECTION 306.     Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security, including a Global Security, is surrendered
to the Trustee or the Company, together with such security, bond or indemnity
as may be required by the Trustee or the Company to save each of them and any
agent of either of them harmless, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a new Security, including a
new Global Security if the mutilated Security was a Global Security, of the
same series and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, including a Global Security if the destroyed, lost or stolen Security
was a Global Security, and (ii) such security or indemnity as may be required
by them to save each of them and any agent of either of them harmless, then, in
the absence of actual notice to the Company or the Trustee that such Security
has been acquired by a bona fide purchaser (or any equivalent person under any
applicable statute, rule or regulation or interpretation then in effect), the
Company shall execute and upon its written request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security, including a Global Security if the destroyed, lost or
stolen Security was a Global Security, of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

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

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

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.  A new
Security shall have such legends as appeared on the destroyed, lost or stolen
Security unless the Company determines otherwise.

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

SECTION 307.     Payment of Interest; Interest Rights Preserved.

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

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

                 (1)      The Company may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Securities of
         such series (or their respective Predecessor Securities) are
         registered at the close of business on a Special Record Date for the
         payment of such Defaulted Interest, which shall be fixed in the
         following manner.  The Company shall notify the Trustee in writing of
         the amount of Defaulted Interest proposed to be paid on each Security
         of such series and the date of the proposed payment, and at the same
         time the Company shall deposit with the Trustee an amount of money
         equal to the aggregate amount proposed to be paid in respect of such
         Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit on or prior to the date of the proposed
         payment, such money when so 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 Securities of such series at such Holder's 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 so mailed,
         such Defaulted Interest shall be paid to the Persons in whose names
         the Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2).

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





                                       27
<PAGE>   34
         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.

         At the option of the Company, interest on any Security may be paid (i)
by mailing a check to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register, the cost of such wire transfer to be borne by the Company.

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

SECTION 308.     Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer or
exchange, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered in the Security
Register as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307)
interest on such Security and for all other purposes whatsoever, whether or not
any payment with respect to such Security shall be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         No holder of any beneficial interest in any Global Security held on 
its behalf by a Depositary (or its nominees) shall have any rights hereunder
with respect to such Global Security or any Security represented thereby, and
such Depositary may be treated by the Company, the Trustee, and any agent of
the Company or the Trustee as the owner of such Global Security or any Security
represented thereby for all purposes whatsoever.  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 a Depositary as Holder of such Global Security, or impair, as
between a Depositary and the owners of beneficial interests in such Global
Security, the operation of customary practices governing the exercise of the
rights of the Depositary (or its nominees) as Holder of such Global Security.
None of the Company, the Trustee or any Paying Agent 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.

SECTION 309.     Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly canceled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities canceled as provided
in this Section, except as expressly permitted hereby.  The Trustee is hereby
directed by the Company to destroy the canceled Securities held by the Trustee,
and the Trustee shall provide the Company with a certificate of a Responsible
Officer certifying as to the destruction of such Securities.

SECTION 310.     Computation of Interest.

         Except as otherwise specified pursuant to Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a 360-day year of twelve 30-day months and no interest will accrue
with respect to the 31st day of any month.  Interest shall be payable through
and excluding any Interest Payment Date and interest shall be payable through
and including any Redemption Date or other principal payment date.

SECTION 311.     Maximum Interest Rate.

         Regardless of any provision contained in any Security or this
Indenture, no Holder shall be entitled to receive, collect or apply as interest
on any Security any amount in excess of the maximum rate permitted by
applicable law, and, in the event that any Holder ever receives, collects, or
applies as interest any such excess, the amount that would be excessive
interest shall be deemed to be a partial prepayment of principal and treated
hereunder as such; and, if the principal amount of any Security is paid in
full, any remaining excess shall forthwith be paid to the Company.

                                  ARTICLE FOUR
                           SATISFACTION AND DISCHARGE

SECTION 401.     Satisfaction and Discharge of Indenture.

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

                 (1)      either

                          (A)     all Securities of such series theretofore
                 authenticated and delivered (other than (i) Securities which
                 have been destroyed, lost or stolen and which have been
                 replaced or paid as provided in Section 306 and (ii)
                 Securities for whose payment money has theretofore been
                 deposited in trust or segregated and held in trust by the
                 Company and thereafter repaid to the Company or discharged
                 from such trust, as provided in Section 1003) have been
                 delivered to the Trustee for cancellation; or

                          (B)     all Securities of such series not theretofore
                 delivered to the Trustee for cancellation

                                  (i)      have become due and payable, or

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

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

                 and the Company, in the case of (i), (ii) or (iii) above, has
                 deposited or caused to be deposited with the Trustee as trust
                 funds in trust for the purpose an amount of money (in the
                 currency in which such Securities are payable) and/or (if such
                 Securities are payable in U.S. dollars) U.S. Government
                 Obligations which through the payment of interest and
                 principal in accordance with their terms, without
                 consideration of any reinvestment thereof, will provide not
                 later than the opening of business on the due dates of any
                 payment of principal (and premium, if any) and interest with
                 respect thereto, or a combination thereof, in an amount
                 sufficient to pay and discharge the entire indebtedness on
                 such Securities not theretofore delivered to the Trustee for
                 cancellation, for principal (and 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 respective Stated
                 Maturity or Redemption Date, as the case may be;

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

                 (3)      the Company has delivered to the Trustee a
         certificate of a nationally-recognized firm of certified public
         accountants certifying as to the sufficiency of the amounts deposited
         pursuant to subclause (B) of clause (1) of this Section for payment of
         the principal (and premium, if any) and interest on the dates such
         payments are due, and an Officers' Certificate and an Opinion





                                       30

         of Counsel, each stating that all conditions precedent herein provided
         for relating to the satisfaction and discharge of this Indenture with
         respect to the Securities of such series have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to a series of Securities, the obligations of the Company and the
Trustee to the Holders of Securities of other series not so satisfied and
discharged, the obligations of the Company to the Trustee under Section 607,
the obligations of the Trustee to any Authenticating Agent under Section 614,
and, if money and/or U.S. Government Obligations shall have been deposited with
the Trustee pursuant to Subclause (B) of clause (1) of this Section, the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003, shall survive.

SECTION 402.     Application of Trust Money.

         Subject to provisions of the last paragraph of Section 1003, all money
and/or U.S. Government Obligations deposited with the Trustee pursuant to
Section 401 and all money received by the Trustee in respect of U.S. Government
Obligations deposited with the Trustee pursuant to Section 401 shall be held in
trust and applied by it, in accordance with the provisions of the Securities of
each series 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 or U.S.
Government Obligations have been deposited with or received by the Trustee; but
such money and/or U.S. Government Obligations need not be segregated from other
funds of the Trustee except to the extent required by law.

SECTION 403.     Defeasance and Discharge of Indenture.

         If principal of and any premium and interest on Securities of any
series are denominated and payable in U.S.  Dollars, the Company shall be
deemed to have paid and discharged the entire indebtedness on all the
Outstanding Securities of such series on the 91st day after the date of the
deposit referred to in subparagraph (d) of this Section, and the provisions
hereof, as it relates to such Outstanding Securities, shall no longer be in
effect (and the Trustee, at the request and expense of the Company, shall
execute proper instruments acknowledging the same), except as to:

                 (a)      the rights of Holders of Securities of such series to
         receive, from the trust funds described in subparagraph (d) of this
         Section, (i) payment of the principal of (and premium, if any) or
         interest on the Outstanding Securities of such series on the Stated
         Maturity of such principal or installment of principal or interest and
         (ii) the benefit of any mandatory sinking fund payments applicable to
         the Securities of such series on the day on which such payments are
         due and payable in accordance with the terms hereof and such
         Securities;





                                       31
<PAGE>   38
                 (b)      the Company's obligations with respect to such 
         Securities under Sections 305, 306, 1002 and 1003; and

                 (c)      the rights, powers, trusts, duties and immunities of
         the Trustee hereunder;

provided that, the following conditions shall have been satisfied:

                 (d)      The Company has deposited or caused to be irrevocably
         deposited with the Trustee (or another trustee satisfying the
         requirements of Section 609) as trust funds in the trust, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of the Securities of such series, (i) U.S.  Dollars in an
         amount, or (ii) U.S. Government Obligations which through the payment
         of interest and principal in respect thereof in accordance with their
         terms will provide not later than one day before the due date of any
         payment referred to in clause (A) or (B) of this subparagraph (d) U.S.
         Dollars in an amount or (iii) a combination thereof, sufficient, in
         the opinion of a nationally recognized firm of independent certified
         public accountants expressed in a written certification thereof
         delivered to the Trustee, to pay and discharge (A) the principal of
         (and premium, if any) and each installment of principal of (and
         premium, if any) and interest on the Outstanding Securities of such
         series on the Stated Maturity of such principal or installment of
         principal and interest and (B) any mandatory sinking fund or analogous
         payments applicable to the Securities of such series on the day on
         which such payments are due and payable in accordance with the terms
         hereof and of such Securities;

                 (e)      such deposit shall not cause the Trustee with respect
         to the Securities of such series to have a conflicting interest as
         defined in Section 608 and for purposes of the Trust Indenture Act
         with respect to such Securities;

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

                 (g)      such provision would not cause any Outstanding
         Securities of such series then listed on the New York Stock Exchange
         or other securities exchange to be delisted as a result thereof;

                 (h)      no Event of Default or event which with notice or
         lapse of time would become an Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit or during the period ending on the 91st day after
         such date;

                 (i)      the Company has delivered to the Trustee an Opinion
         of Counsel to the effect that Holders of the Securities of such series
         will not recognize income, gain or loss for federal income tax
         purposes as a result of such





                                       32
<PAGE>   39
         deposits, defeasance and discharge and will be subject to federal
         income tax on the same amount and in the same manner and at the same
         times, as would have been the case if such deposit, defeasance and
         discharge had not occurred; and

                 (j)      the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all
         conditions precedent relating to the defeasance contemplated by this
         Section have been complied with.

SECTION 501.     Events of Default.

         "Event of Default", wherever used herein with respect to Securities of
any series, and unless otherwise provided with respect to Securities of any
series pursuant to Section 301, means any one of the following events (whatever
the reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

                 (1)      default in the payment of any interest upon any
         Security of such series when it becomes due and payable, and
         continuance of such default for a period of 30 consecutive days (for
         Securities of any series the interest on which is payable less
         frequently than monthly) or for a period of 10 consecutive days (for
         Securities of any series the interest on which is payable monthly);

                 (2)      default in the payment of the principal of (or
         premium, if any, on) any Security of such series when due and payable;

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

                 (4)      default in the performance, or breach, of any
         covenant or warranty of the Company herein or the Securities of such
         series (other than a covenant or warranty a default in the performance
         or breach of which is elsewhere in this Section specifically dealt
         with or which has expressly been included herein solely for the
         benefit of a series of one or more Securities other than such series),
         and continuance of such default or breach for a period of 30
         consecutive days after written notice thereof has been received by the
         Company from the Trustee or by the Company and the Trustee from the
         Holders of at least 25% in aggregate principal amount of the
         Outstanding Securities of such series, specifying such default or
         breach and requiring it to be remedied and stating that such notice is
         a "Notice of Default" hereunder;





                                       33
<PAGE>   40
                 (5)      the occurrence of an event of default, as defined in
         any indenture or instrument under which the Company or any Material
         Subsidiary shall have Outstanding at least $1,000,000 aggregate
         principal amount of indebtedness, shall happen and be continuing and
         such indebtedness shall, as a result thereof, have been accelerated
         (or comparable event shall have occurred) so that the same shall have
         become due and payable prior to the date on which the same would
         otherwise have become due and payable and such acceleration has been
         in effect without rescission or annulment for a period of 30
         consecutive days; provided, however, that if such event of default
         under such indenture or instrument shall be remedied or cured by the
         Company or waived by the holders of such indebtedness, or if such
         acceleration under such indenture or instrument shall have been
         rescinded or annulled by the holders of such indebtedness, then,
         unless the Securities of such series shall have been accelerated as
         provided herein, the Event of Default hereunder by reason thereof
         shall be deemed likewise to have been thereupon remedied, cured or
         waived without further action upon the part of either the Trustee or

                 (9)      any other Event of Default provided with respect to
         Securities of such series pursuant to Section 301.

SECTION 502.     Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Outstanding Securities of any
series occurs and is continuing, then and in every such case the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities of such series may declare the principal amount (or, if any of the
Securities of such series are Original Issue Discount Securities, such lesser
portion of the principal amount of such Securities as may be specified in the
terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
portion thereof) shall become immediately due and payable; provided that in the
case of an Event of Default described in Section 501(6) or (7), the principal
amount of all Securities (or specified portion thereof) shall become due and
payable immediately, without any notice to the Company or the Trustee.

         Upon payment of such principal amount (and premium, if any), such
interest and interest on overdue principal and overdue interest to the extent
prescribed therefor in the Securities of such series (to the extent payment of
such interest is legally enforceable), all of the Company's obligations in
respect of the payment of principal and interest on the Securities of such
series shall terminate.

         At any time after such a declaration of acceleration with respect to
Outstanding Securities of any series has been made and before a judgment or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of such series, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if





                                       35
<PAGE>   42
                 (1)      the Company has paid or deposited with the Trustee a
         sum sufficient to pay

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

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

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

                          (D)     all sums paid or advanced by the Trustee
                 hereunder and the reasonable compensation, expenses,
                 disbursements and advances of the Trustee, its agents and
                 counsel, and any other amounts due the Trustee under Section
                 607; and

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

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

SECTION 503.     Collection of Indebtedness and Suits for Enforcement by
                 Trustee.

         The Company covenants that if

                 (1)      default is made in the payment of any interest on any
         Security of any series when such interest becomes due and payable and
         such default continues for a period of 30 consecutive days (for
         Securities of any series the interest on which is payable less
         frequently than monthly) or for a period of 10 days (for Securities of
         any series the interest on which is payable monthly), or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Security, the whole amount then due and payable on such
Security for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest at the rate
or rates prescribed therefor in such Security, and, in addition thereto such
further amount as shall be sufficient





                                       36
<PAGE>   43
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

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

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

         The rights and remedies under this Section 503 are in addition to the
other rights and remedies available under this Article 5 or otherwise legally
available.

SECTION 504.     Trustee May File Proofs of Claim.

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

                 (i)      to file and prove a claim for the whole amount of
         principal (and premium, if any) or such portion of the principal
         amount of any series of Original Issue Discount Securities as may be
         specified in the terms of such series and interest owing and unpaid in
         respect of the Securities of such series 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 any other amounts due the Trustee under
         Section 607) and of the Holders allowed in such judicial proceeding,
         and

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





                                       37
<PAGE>   44
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
607.

         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
of any series 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.

SECTION 505.     Trustee May Enforce Claims Without Possession of Securities.

         All rights of action and claims hereunder or the Securities may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and for any
other amounts due the Trustee under Section 607, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

SECTION 506.     Application of Money Collected.

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

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

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

                 THIRD: The balance, if any, to the Person or Persons entitled
         thereto.

<PAGE>   45
SECTION 507.     Limitation on Suits.

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

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

                 (2)      the Holders of not less than 25% in principal amount
         of the Outstanding Securities of such series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

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

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

                 (5)      no direction inconsistent with such written request
         has been given to the Trustee during such 60-day period by the Holders
         of a majority in principal amount of the Outstanding Securities of
         such series; it being understood and intended that no one or more of
         such Holders shall have any right in any manner whatever by virtue of,
         or by availing of, any provision hereof to affect, disturb or
         prejudice the rights of any other of such Holders, or to obtain or to
         seek to obtain priority or preference over any other of such Holders
         or to enforce any right hereunder, except in the manner herein
         provided and for the equal and ratable benefit of all of such Holders.

SECTION 508.     Unconditional Right of Holders to Receive Principal, Premium
                 and Interest.

         Notwithstanding any other provision herein, the Holder of any Security
shall have the right, which is absolute and unconditional, to receive payment
of the principal of (and premium, if any) and (subject to Section 307) interest
on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date, or, in the
case of a repurchase right at the option of the Holder, if any, on the
repurchase date specified pursuant to Section 301) and to institute suit for
the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.





                                       39
<PAGE>   46
SECTION 509.     Restoration of Rights and Remedies.

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

SECTION 510.     Rights and Remedies Cumulative.

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

SECTION 511.     Delay or Omission Not Waiver.

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

SECTION 512.     Control by Holders.

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

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

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





                                       40
<PAGE>   47
                 (3)      subject to Section 601, the Trustee need not take any
         action which might be unjustly prejudicial to the rights of the other
         Holders of Securities not joining in such action.

SECTION 513.     Waiver of Past Defaults.

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

                 (1)      in the payment of the principal of (or premium, if
         any) or interest on any Security of such series when due (other than
         amounts due and payable solely upon acceleration pursuant to Section
         502), unless theretofore paid in full and cured in accordance with the
         terms hereof, or

                 (2)      in respect of a covenant or provision hereof which
         under Section 902 cannot be modified or amended without the consent of
         the Holder of each Outstanding Security of such series affected.

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

SECTION 514.     Undertaking for Costs.

         All parties hereto agree, and each Holder of any Security by such
Holder's acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy hereunder, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; provided,
however, that the provisions of this Section shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 25% in principal amount of the Outstanding Securities of the affected
series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Security on
or after the Stated Maturity or Maturities expressed in such Security (or, in
the case of redemption, on or after the Redemption Date or, in the case of a
repurchase right at the option of the Holder, if any, on the repurchase date
specified pursuant to Section 301).

SECTION 515.     Waiver of Stay or Extension Laws.

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

                                  ARTICLE SIX
                                  THE TRUSTEE

SECTION 601.     Certain Duties and Responsibilities.

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

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

                 (2)      in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         hereof; 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 hereof.

         (b)     With respect to Securities of any series, in case an Event of
Default has occurred and is continuing with respect to that series only, the
Trustee shall exercise such of the rights and powers vested in it hereby, 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 such person's
own affairs.

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

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

<PAGE>   49
                 (2)      the Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer, unless it shall
         be proved that the Trustee was negligent in ascertaining the pertinent
         facts;

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

                 (4)      no provision hereof shall require the Trustee to
         expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

         (d)     Whether or not therein expressly so provided, every provision
hereof relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

SECTION 602.     Notice of Defaults.

         Within 90 days after the occurrence of any Event of Default hereunder
with respect to the Securities of any series, the Trustee shall transmit by
mail to all Holders of Securities of such series, as their names and addresses
appear in the Security Register, notice of such default hereunder known to the
Trustee, unless such default shall have been cured or waived; provided however,
that, except in the case of a default in the payment of the principal of (or
premium, if any) or interest on any Security of such series or in the payment
of any sinking fund installment with respect to Securities of such series, the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Holders of Securities of
such series; and provided, further, that in the case of any default of the
character specified in Section 501(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof.  For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would
become, an Event of Default with respect to Securities of such series.

                 (f)      the Trustee shall not be bound to make any

         such facts or matters as it may see fit, and, if the Trustee shall
         determine to make such further inquiry or investigation, it shall be
         entitled to examine, during business hours and upon reasonable notice,
         the books, records and premises of the Company pertaining to the
         Securities, personally or by agent or attorney;

SECTION 604.     Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities of each series,
except the Trustee's certificates of authentication, shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness.  The Trustee makes no
representations as to the validity or sufficiency hereof or of the Securities
of any series, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture and any supplemental indenture, to
authenticate such Securities and to perform its obligations hereunder and such
Securities.  The Trustee or any Authenticating Agent shall not be accountable
for the use or application by the Company of Securities of any series or the
proceeds thereof.

SECTION 605.     May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to TIA

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

SECTION 606.     Money Held in Trust.

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





                                       45
<PAGE>   52
                 (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 hereof (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 the Trustee's negligence, bad faith or willful
         misconduct; and

                 (3)      to indemnify the Trustee and its agents for, and to
         hold them harmless against, any loss, liability or expense incurred
         without negligence, bad faith 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 themselves against any claim or liability in connection with
         the exercise or performance of any of their powers or duties
         hereunder.

         (b)     As security for the performance of the obligations of the
Company under this Section, the Trustee shall have a lien prior to the
Securities upon all property and funds held or collected by the Trustee as
such, except funds held in trust for the payment of principal of and interest
on the Securities of any series.  "Trustee" for the purposes of this Section
includes any predecessor Trustee, but negligence, bad faith or willful
misconduct of any Trustee shall not be attributable to any other Trustee.

         (c)     When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(6) or (7), the
expenses and the compensation for such services are intended to constitute
expenses of administration under any bankruptcy law.

SECTION 608.     Disqualification; Conflicting Interests.

         The provisions of TIA Section 310(b) shall apply to the Trustee.

SECTION 609.     Corporate Trustee Required; Eligibility.

eligible to act under TIA Section 310(a)(1) and whose parent shall have a
combined capital and surplus of at least $50,000,000 and subject to supervision
or examination by federal, state or District of Columbia authority.  If such
Corporation 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 Corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter
specified in this Article.  Neither the Company, nor any Person directly or
indirectly controlling, controlled by or under common control with the Company,
shall act as Trustee hereunder.

SECTION 610.     Resignation and Removal; Appointment of Successor.

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

         (b)     The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company specifying its intention to resign, the applicable series affected by
such resignation, the reason therefor and the date upon which such resignation
shall become effective.  Notwithstanding the foregoing, unless the reason for
such resignation is a conflict pursuant to Section 608, the Trustee must resign
with respect to all Securities if the Trustee resigns with respect to any
series of Securities.  If the instrument of acceptance by a successor Trustee
required by Section 611 shall not have been delivered to the Trustee within 30
days after the giving of such notice of resignation, the resigning Trustee may
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

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

         (d)     The Trustee may be removed with respect to any or all series
of Securities at any time upon 30 days notice by filing with it an instrument
in writing signed on behalf of the Company by a duly authorized officer of the
Company specifying such removal and the date on which it is to become
effective.

         (e)     If at any time:

                 (1)      the Trustee shall fail to comply with Section 310(b)
         of the TIA 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,

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

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

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to any one or more series of Securities or all Securities
or (ii), subject to Section 514, any Holder who has been a bona fide Holder of
a Security for





                                       47
<PAGE>   54
at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Trustee with respect to such series of Securities and the appointment of a
successor Trustee or Trustees.

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

         (g)     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
by mailing written notice of such event by first-class mail, postage prepaid,
to all Holders of Securities of such series as their names and addresses appear
in the Security Register.  Each notice shall include the name of the successor
Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office.

SECTION 611.     Acceptance of Appointment by Successor.

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





                                       48
<PAGE>   55
powers, trusts and duties hereunder 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.

         (b)     In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such
appointment and which (1) shall contain such provisions as shall be necessary
or desirable to transfer and confirm to, and to vest in, each successor Trustee
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Securities, shall contain such provisions as shall be deemed
necessary or desirable to confirm that all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee and (3) shall add to or change any of the
provisions hereof 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.  Whenever
there is a successor Trustee with respect to one or more (but less than all)
series of securities issued pursuant hereto, the terms "Indenture" and
"Securities" shall have the meanings specified in the provisos to the
respective definitions of those terms in Section 101 which contemplate such
situation.

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

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





                                       49
<PAGE>   56
SECTION 612.     Merger, Conversion, Consolidation or Succession to Business.

         Any Corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any Corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any Corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such Corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities;
in case any of the Securities shall not have been authenticated by the Trustee
then in office, any successor by merger, conversion or consolidation to such
Trustee may authenticate such Securities either in the name of such predecessor
hereunder or in the name of the successor Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Securities
or in this Indenture provided that the certificate of the Trustee shall have;
provided, however, that the right to adopt the certificate of authentication of
any predecessor Trustee or to authenticate Securities in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

SECTION 613.     Preferential Collection of Claims Against Company.

         The Trustee shall comply with TIA Section 311(a).  A Trustee which has
resigned or been removed is subject to TIA Section 311(a) to the extent
indicated therein.

SECTION 614.     Appointment of Authenticating Agent.

         At any time when any of the Securities remain Outstanding the Trustee,
with the concurrence of the Company, 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, and Securities so authenticated shall be entitled to the benefits
hereof and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder.  Wherever reference is made herein 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, state or District of Columbia
authority.  If such Authenticating Agent publishes reports of





                                       50
<PAGE>   57
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

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

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company.  Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall 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.

         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 reimbursement for such payments subject to Section
607.

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





                                       51
<PAGE>   58
         This is one of the Securities of the series designated herein and
issued pursuant to the within-mentioned Indenture.

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

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

<PAGE>   62
                 (5)      to add to, change or eliminate any of the provisions
         hereof 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 such Security Outstanding;

                 (6)      to secure the Securities of any series, provided that
         such security does not cause the Trustee with respect to the
         Securities of that series to have a conflicting interest as defined in
         Section 608 and for purposes of the TIA with respect to the Securities
         of any series;

         the administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 611(b); or

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

SECTION 902.     Supplemental Indentures With Consent of Holders.

         With the consent of the Holders of not less than a majority in
aggregate principal amount of the Securities of each series at the time
Outstanding affected by such supplemental indenture (voting as one class), 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 hereof or of
modifying in any manner the rights of the Holders of Securities of each series
hereunder; 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 such affected
         Security, or reduce the principal amount thereof or the rate of
         interest thereon or any premium payable upon the redemption thereof,
         or reduce the amount of the principal of an Original Issue Discount
         Security that would be due and payable upon a





                                       56
<PAGE>   63
         declaration of acceleration of the Maturity thereof pursuant to
         Section 502, or change any Place of Payment where, or the coin or
         currency in which, any such Security or any premium or the interest
         thereon is payable, or impair the right to institute suit for the
         enforcement of any such payment on or after the Stated Maturity
         thereof (or, in the case of redemption or repayment, on or after the
         Redemption Date or any repayment date),

                 (2)      reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any modifications or amendments hereto with respect to
         such series or to the terms and conditions of such series or to
         approve a supplemental indenture with respect to such series, or the

         defaults hereunder and their consequences provided for herein, or

                 (3)      modify any of the provisions of this Section 902,
         Section 513 or 1011, except to increase any such percentage or to
         provide that certain other provisions hereof cannot be modified or
         waived without the consent of the Holder of each Outstanding Security
         affected thereby; provided however, that this clause shall not be
         deemed to require the consent of any Holder with respect to changes in
         the references to "the Trustee" and concomitant changes in this
         Section 902 and Section 1009, or the deletion of this proviso, in
         accordance with the requirements of Sections 611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision hereof 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 hereunder of the Holders of
Securities of any other series.

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

SECTION 903.     Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created hereby, the Trustee shall be entitled to receive, and
(subject to Section 601 hereof) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is

<PAGE>   64
SECTION 904.     Effect of Supplemental Indentures.

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

SECTION 905.     Conformity with Trust Indenture Act.

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

SECTION 906.     Reference in Securities to Supplemental Indentures.

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

SECTION 907.     Notice of Supplemental Indentures

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provision of Section 902, the Company
shall give notice thereof to the Holders of each Outstanding Security so
affected, pursuant to Section 106, setting forth in general terms the substance
of such supplemental indenture.

                                   COVENANTS

SECTION 1001.    Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of

if any) and interest on the Securities of such series in accordance with the
terms of such Securities and this Indenture.

<PAGE>   65
SECTION 1002.    Maintenance of Office or Agency.

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

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

SECTION 1003.    Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum in the currency in which such series of Securities is payable
sufficient to pay the principal (and premium, if any) or interest so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its failure so to act.

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

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee or the Company to execute and deliver to the Trustee an
instrument





                                       59
<PAGE>   66
in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will:

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

                 (2)      give the Trustee notice of any Event of Default by
         the Company (or any other obligor upon the Securities of such series)
         in the making of any payment of principal (and premium, if any) or
         interest on the Securities of such series; and

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

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge hereof 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 terms as those upon which such sums were held by the Company or such
Paying Agent, and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest shall have 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.

SECTION 1004.    Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things reasonably necessary to preserve and keep in full force and effect its
corporate existence, rights (charter and statutory) and franchises of the
Company and its Material Subsidiaries; 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 its Material Subsidiaries and
that the loss thereof will not have a material adverse effect on the business
or financial condition of the Company and its Subsidiaries, taken as a whole.

SECTION 1005.    Maintenance of Properties.

         The Company will:

                 (1)      cause its properties and the properties of its
         Material Subsidiaries (other than properties obtained by the Company
         or any Material Subsidiary through foreclosure or other resolution of
         any loan) used or useful in the conduct of the business of the Company
         and its Material Subsidiaries to be maintained and kept in good
         condition, repair and working order and supplied with all necessary
         facilities and equipment and will cause to be made all necessary
         repairs, renewals, replacements, betterments and improvements thereof,
         all as in the judgment of the Company may be necessary so that the
         business carried on in connection therewith may be properly and
         advantageously conducted at all times; provided, however, that the
         foregoing shall not prevent the Company or a Material Subsidiary from
         discontinuing the operation and maintenance of any of its properties
         if such discontinuance is, in the judgment of the Company, desirable
         in the conduct of its business and will not have a material adverse
         effect on the business or financial condition of the Company and its
         Subsidiaries, taken as a whole;

                 (2)      take all appropriate steps to preserve, protect and
         maintain the trademarks, trade names, copyrights, licenses and permits
         used in the conduct of the business of the Company and its Material
         Subsidiaries; provided, however, that the foregoing shall not prevent
         the Company or a Material Subsidiary from selling, abandoning or
         otherwise disposing of any such trademark, trade name, copyright,
         license or permit if such sale, abandonment or disposition is, in the
         judgment of the Company, desirable in the conduct of its business and
         will not have a material adverse effect on the business or financial
         condition of the Company and its Subsidiaries, taken as a whole; and

                 (3)      The Company and each of its Material Subsidiaries
         shall comply with all statutes, laws, ordinances, or government rules
         and regulations to which it is subject, noncompliance with which would
         materially adversely affect the business or financial condition of the
         Company and its Subsidiaries, taken as a whole.

SECTION 1006.    Insurance.

         The Company shall carry and maintain, and cause each of its
Subsidiaries to carry and maintain, insurance with financially sound and
reputable insurance companies or associations in such amounts and covering such
risks as is usually carried by similarly-situated companies engaged in similar
operations and owning similar properties in similar geographic areas in which
the Company or such Subsidiary operates, provided that such insurance is
generally available at commercially reasonable rates, and further provided that
the Company may self-insure, or insure through captive insurers or insurance
cooperatives to the extent consistent with prudent business practices.  Such
insurance shall be in such amounts,





                                       61
<PAGE>   68
contain such terms, be in such forms and be for such periods as are customary
for such similarly-situated companies in the Company's industry or insurance
markets reasonably accessible by the Company.  The Company will provide and
will cause each Subsidiary to provide such information and documents reasonably
requested by the Trustee from time to time with respect to the Company's
provision for insurance.  The obligations evidenced by this covenant shall be
interpreted to reflect changes in insurance practices related to the method in
which insurance risks are covered in the North American and European markets or
in any other market in which the Company or its Subsidiaries, as the case may
be, reasonably places coverage.

SECTION 1007.    Payment of Taxes and Other Claims.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all material taxes, assessments
and governmental charges levied or imposed upon the Company or any Subsidiary
or upon the income, profits or property of the Company or any Subsidiary and
(2) all material lawful claims for labor, material and supplies which, if
unpaid, might by law become a lien upon the property of the Company or any
Subsidiary; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings and for which disputed amounts adequate reserves
have been established in accordance with GAAP.

SECTION 1008.    Books and Records.

                 The Company shall, and shall cause each Material Subsidiary
         to, at all times keep proper books of record and account in which
         proper entries shall be made in accordance with GAAP and, to the
         extent applicable, regulatory accounting principles.

SECTION 1009.    Defeasance of Certain Obligations.

         The following provisions shall apply to the Securities of each series
unless specifically otherwise provided in a Board Resolution, Officers'
Certificate or indenture supplemental hereto provided pursuant to Section 301.
The Company may omit to comply with any term, provision or condition set forth
in Article Ten and Section 301(12) and any such omission with respect to
Article Ten and to Section 301(12) shall not be an Event of Default, in each
case with respect to the Securities of that series, provided that the following
conditions have been satisfied:

                 (1)      with reference to this Section 1009, the Company has
         deposited or caused to be irrevocably deposited with the Trustee (or
         another trustee satisfying the requirements of Section 609) as trust
         funds in trust, specifically pledged as security for, and dedicated
         solely to, the benefit of the Holders of the Securities of that
         series, (i) money in an amount, (ii) U.S. Government Obligations which
         through the payment of interest and principal in respect thereof in
         accordance with their terms will provide not later than one day





                                       62
<PAGE>   69
         before the due date of any payment referred to in clause (A) or (B) of
         this subparagraph (1) money in an amount or (iii) a combination
         thereof, sufficient, in the opinion of a nationally-recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge (A) the
         principal of (and premium, if any) and each installment of principal
         (and premium, if any) and interest on the Outstanding Securities on
         the Stated Maturity of such principal or installments of principal and
         interest and (B) any mandatory sinking fund payments or analogous
         payments applicable to the Securities of such series on the day on
         which such payments are due and payable in accordance with the terms
         hereof and of such Securities;

                 (2)      such deposit shall not cause the Trustee with respect
         to the Securities of that series to have a conflicting interest as
         defined in Section 608 and for purposes of the Trust Indenture Act
         with respect to the Securities of any series;

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

                 (4)      no Event of Default or event which with notice or
         lapse of time would become an Event of Default with respect to the
         Securities of that series shall have occurred and be continuing on the
         date of such deposit;

                 (5)      the Company has delivered to the Trustee an Opinion
         of Counsel to the effect that Holders of the Securities of such series
         will not recognize income, gain or loss for federal income tax
         purposes as a result of such deposit and defeasance of certain
         obligations and will be subject to federal income tax on the same
         amount and in the same manner and at the same times as would have been
         the case if such deposit and defeasance had not occurred; and

                 (6)      the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all
         conditions precedent herein provided for relating to the defeasance
         contemplated in this Section 1009 have been complied with.

SECTION 1010.    Statement by Officers as to Default.

                 (1)      The Company will deliver to the Trustee, within 45
         days after the end of each calendar quarter, an Officers' Certificate,
         stating whether or not to the best knowledge of the signers thereof
         the Company is in default in the performance and observance of any of
         the terms, provisions and conditions hereof (other than a term,
         provision or condition specifically dealt with in Clause (2) of this
         Section 1011) and, if the Company shall be in default, specifying all
         such defaults and the nature and status thereof of which they may have
         knowledge.

<PAGE>   70
                 (2)      The Company will deliver to the Trustee, within five
         days after any officer eligible hereunder to sign an Officers'
         Certificate becomes aware of the occurrence thereof, written notice of
         any event which after notice or lapse of time or both would become an
         Event of Default pursuant to Clause (5) of Section 501.

SECTION 1011.    Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Article Ten and Section 301(12),
inclusive, with respect to the Securities of any series if before the time for
such compliance the Holders of not less than a majority in aggregate principal
amount of the Outstanding Securities of such series shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any such term,
provision or condition.  If a record date is fixed for such purpose, the
Holders on such record date or their duly designated proxies, and only such
Persons, shall be entitled to waive any such term, provision or condition
hereunder, whether or not such Holders remain Holders after such record date;
provided that unless the Holders of not less than a majority in principal
amount of the Outstanding Securities of such series shall have waived such
term, provision or condition prior to the date which is 90 days after such
record date, any such waiver previously given shall automatically and without
further action by any Holder be canceled and of no further effect.

SECTION 1012.    Exceptions to Covenants.

         The Company shall not, and shall not permit any Subsidiary to, take or
permit to be taken any action or fail to take any action which is permitted by
any of the covenants contained herein if such action or omission would result
in the breach of any other covenant contained herein.

SECTION 1102.    Election to Redeem; Notice to Trustee.

         The election of the Company to redeem Securities of any series shall
be evidenced by an Officers' Certificate.  The Company shall, at least 45 days
prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of

                 (1)      such Redemption Date,

                 (2)      the Redemption Price,

                 (3)      if the Securities of such series have different terms
         and less than all of the Securities of such series are to be redeemed,
         the terms of the Securities to be redeemed,

                 (4)      whether the redemption is pursuant to a mandatory or
         optional sinking fund, or both, if such is the case, and

                 (5)      if less than all the Securities of such series with
         identical terms are to be redeemed, the principal amount of such
         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 herein, the Company shall furnish the Trustee with an Officers'
Certificate evidencing compliance with such restriction.

SECTION 1103.    Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities of like tenor of any series are to be
redeemed, the particular Securities to be redeemed shall be selected not less
than nor more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of like tenor of such series not previously called
for redemption, by lot or by such other 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 like
tenor of that series or any integral multiple thereof of the principal amount
of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series).

         The Trustee shall promptly notify the Company 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 hereof, 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.

<PAGE>   72
SECTION 1104.    Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption

address appearing in the Security Register.

         All notices of redemption shall state:

                 (1)      the Redemption Date,

                 (2)      the Redemption Price,

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

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

                 (5)      the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

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

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Trustee in the name and at the expense of the
Company, unless the Company notifies the Trustee of its intention to give such
notice directly to each Holder.

SECTION 1105.    Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money in immediately available funds 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 1106.    Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in





                                       66
<PAGE>   73
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that, unless otherwise specified as contemplated by Section
301, installments of interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms and the provisions of
Section 307.

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

SECTION 1107.    Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment for such series (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or such Holder's attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same
series and of like tenor, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.  To the
extent a series of Securities represented by a Global Security is to be
redeemed only in part, a notation of such redemption shall be made by the
Trustee in the schedule of exchanges on the Global Security.

                                 ARTICLE TWELVE

any sinking fund payment with respect to the Securities of like tenor 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.  Such Securities
shall be first applied to the sinking fund payment next due and any excess
shall be applied to the following sinking fund payments in the order they are
due.

SECTION 1203.    Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for
Securities of like tenor of a series, the Company will deliver to the Trustee

time of delivery of such Officers' Certificate, will also deliver to the
Trustee any Securities to be so delivered.  Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
1103 and cause notice of the redemption thereof to be given in the name of and

                 (5)      that exercise of the option to elect repurchase is

of such redemption shall be made by the Trustee in the schedule of exchanges on
the Global Security.

                                 AMRESCO, INC.

                      Senior Notes, Series 1996-A due 1999

                    Officer's Certificate and Company Order

         Pursuant to the Senior Notes Indenture dated as of July 1, 1996 (the
"Master Indenture") between AMRESCO, INC.  (the "Company") and Comerica Bank,
as Trustee (the "Trustee"), resolutions adopted by the Company's Board of
Directors on May 29, 1996 and resolutions adopted by the Company's Pricing
Committee as of July 15, 1996, this Officers' Certificate and Company Order is
being delivered to the Trustee to establish the terms of a series of Securities
in accordance with Section 301 of the Master Indenture, to establish the form
of the Securities of such series in accordance with Section 201 of the Master
Indenture and to establish the procedures for the authentication and delivery
of the Securities of such series pursuant to Section 303 of the Master
Indenture.

         Capitalized terms used and not otherwise defined herein shall have the
meanings assigned to them in the Master Indenture.

         The Company has complied with all conditions precedent provided for in
the Master Indenture relating to the establishment of (i) a series of
Securities, (ii) the forms of such series of Securities and (iii) the
procedures for the authentication and delivery of such series of Securities.

A.       Establishment of Series Pursuant to Section 301 of the Master
Indenture.

         The Company hereby establishes, pursuant to Section 301 of the Master
Indenture, a series of Securities that shall have the following terms:

         1.      The series of Securities being authorized hereby shall bear 
the title "Senior Notes, Series 1996-A due 1999" (the "Notes").

         2.      The aggregate principal amount of the Notes shall be limited to
$57,500,000 (except for Notes authenticated and delivered pursuant to Section
306 of the Master Indenture, and except for any Notes which, pursuant to
Section 303 of the Master Indenture, are deemed never to have been
authenticated and delivered thereunder).

         3.      Interest on each Note shall be payable to the Person in whose 
name such Note is registered at the close of business on the tenth day of the 
month (whether or not a Business Day) in the same month as the relevant 
Interest Payment Date (as defined in paragraph 5 hereof).
        
         4.      The Notes shall mature on July 1, 1999, at which time the 
entire principal amount of the Notes and accrued but unpaid interest on the 
Notes will be due and payable.
<PAGE>   2
         5.      Each Note shall bear interest at the annual rate of 8.75% 
commencing on the date of original issuance.  Interest on the Notes shall be 
payable from their original date of issuance on the 15th day of each month,
or, if any such day is not a Business Day, on the next succeeding Business Day
(each an "Interest Payment Date"), based on a 360-day year of twelve 30-day
months.  Interest payable on any Interest Payment Date shall include interest
on the Notes to and excluding such Interest Payment Date.  The first Interest
Payment Date shall be September 15, 1996, and shall include interest from the
date of original issuance to and excluding the first Interest Payment Date.

          6.     The principal of (and premium, if any) and interest on the 
Notes shall be payable, and the transfer of the Notes shall be registrable and 
Notes shall be exchangeable for Notes bearing identical terms and provisions, 
at the Corporate Trust Office of the Trustee or such other location as the 
Trustee shall specify.  Interest on the Notes may, at the option of the 
Company, be paid by check mailed to the address of the Person entitled thereto 
as it appears on the Security Register.

          7.     Notes may not be redeemed by the Company at the option of the 
Company prior to maturity.

          8.     The Company shall have no obligation to redeem or purchase 
Notes at the option of a Holder thereof or pursuant to any sinking fund or 
analogous provisions, except as set forth below:

                 (a)      Right to Require Repurchase.  In the event that there
          shall occur a Repurchase Event (as defined in paragraph (g)), then
          each Holder shall have the right, at such Holder's option, to require
          the Company to purchase, and upon the exercise of such right, the
          Company shall purchase, all or any part of such Holder's Notes on the
          date (the "Repurchase Date") that is 30 days after the date the
          Company gives notice of the Repurchase Event as contemplated in
          paragraph (b)(1) at a price (the "Repurchase Price") equal to 100% of
          the principal amount thereof, together with accrued and unpaid
          interest to the Repurchase Date.  Such right to require the
          repurchase of Notes shall not continue after a discharge of the
          Company from its obligations with respect to the Notes in accordance
          with Article Four of the Master Indenture.

                 (b)      Notice; Method of Exercising Repurchase Right.

                          (1)     On or before the 15th day after the
                 Repurchase Event, the Company, or, upon Company Request
                 transmitted to the Trustee within 5 days of such Repurchase
                 Event, the Trustee (in the name and at the expense of the
                 Company), shall give notice of the occurrence of the
                 Repurchase Event and of the repurchase right set forth herein
                 arising as a result thereof by first-class mail, postage
                 prepaid, to each Holder of the Notes at such Holder's address
                 appearing





<PAGE>   3
                 in the Note Register.  Such notice shall be deemed to have
                 been given at the time of posting of such first-class mail.
                 The Company shall also deliver a copy of such notice of a
                 repurchase right to the Trustee.

                 Each notice of a repurchase right shall state:

                          (i)     that the notice is being made pursuant to
                                  paragraph 8(a) of this Officer's Certificate
                                  and Company Order and a description of the
                                  circumstances triggering the repurchase
                                  right,

                          (ii)    the Repurchase Date,

                          (iii)   the date by which the repurchase right must 
                                  be exercised,

                          (iv)    the Repurchase Price, and

                          (v)     the instructions a Holder must follow to 
                                  exercise a repurchase right.

                          No failure of the Company to give the foregoing
                 notice shall limit any Holder's right to exercise a repurchase
                 right.  The Trustee shall have no affirmative obligation to
                 determine if there shall have occurred a Repurchase Event.

                          (2)     To exercise the repurchase right, a Holder
                 shall deliver to the Company (or an agent designated by the
                 Company for such purpose in the notice referred to in (1)
                 above) and to the Trustee on or before the fifteenth (15th )
                 day prior to the Repurchase Date (i) written notice of the
                 Holder's exercise of such right, which notice shall set forth
                 the name of the Holder, the principal amount of the Note or
                 Notes (or portion of a Note) to be repurchased, and a
                 statement that an election to exercise the repurchase right is
                 being made thereby, and (ii) the Note or Notes with respect to
                 which the repurchase right is being exercised, duly endorsed
                 for transfer to the Company, if any such Note (other than in
                 global book-entry form), is issued to such Holder.  Such
                 written notice shall be irrevocable following the close of
                 business on the fifth (5th) day prior to the Repurchase Date;
                 provided, however, that the Company, in its sole and absolute
                 discretion, may consent to the withdrawal of any Notes after
                 such date and prior to the Repurchase Date.  If the Repurchase
                 Date falls between any Regular Record Date and the next
                 succeeding Interest Payment Date, Notes to be repurchased must
                 be accompanied by a check from the Holder of an amount equal
                 to the interest thereon which the registered Holder thereof is
                 to receive on such Interest Payment Date.  Upon receipt of any
                 such check, the Trustee shall forward such check to the
                 Company.





                                       3
<PAGE>   4
                          (3)     In the event a repurchase right shall be
                 exercised in accordance with the terms hereof, the Company
                 shall on the Repurchase Date pay or cause to be paid in cash
                 to the Holder thereof the Repurchase Price of the Note or
                 Notes as to which the repurchase right had been exercised.  In
                 the event that a repurchase right is exercised with respect to
                 less than the entire principal amount of a surrendered Note,
                 the Company shall execute and deliver to the Trustee and the
                 Trustee shall authenticate for issuance in the name of the
                 Holder a new Note or Notes in the aggregate principal amount
                 of the unrepurchased portion of such surrendered Note.

                 (c)      Deposit of Repurchase Price.  On or before the
         Repurchase Date, the Company shall deposit with the Trustee or with a
         Paying Agent (or, if the Company is acting as its own Paying Agent,
         segregate and hold in trust as provided in Section 1003 of the Master
         Indenture) an amount of money, which shall be good funds on the
         Repurchase Date, sufficient to pay the Repurchase Price of the Notes
         which are to be repurchased on the Repurchase Date.

                 (d)      Notes Not Repurchased on Repurchase Date.  If a Note
         surrendered for repurchase shall not be so paid on the Repurchase
         Date, the principal shall, until paid, bear interest to the extent
         permitted by applicable law from the Repurchase Date at the rate per
         annum borne by such Note.

                 (e)      Notes Repurchased In Part.  Any Note which is to be
         repurchased only in part shall be surrendered at any office or agency
         of the Company designated for that purpose pursuant to Section 1002 of
         the Master Indenture (with, if the Company or the Trustee so requires,
         due endorsement by, or 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 Note without service charge, a new Note or Notes
         of any authorized denomination as requested by such Holder, in
         aggregate principal amount equal to and in exchange for the
         unrepurchased portion of the principal of the Note so surrendered.

                 (f)      Priority of Repurchase Rights.  If the Repurchase
         Event is effected with respect to Subordinated Debt, the Holders of
         the Notes requiring the Company to repurchase Notes must be paid in
         full pursuant to the terms and conditions of this paragraph 8 prior to
         any payments being made to the Holders of Subordinated Debt.  If the
         Repurchase Event is effected with respect to Senior Debt, the Holders
         of the Notes requiring the Company to repurchase Notes must be paid
         concurrently with the Holders of such Senior Debt.

                 (g)      Definition of Repurchase Event.  For purposes of this
         paragraph 8, a "Repurchase Event" shall have occurred upon the
         occurrence of any event requiring that





                                       4
<PAGE>   5
         the Company repurchase, or make an offer to repurchase, any
         Subordinated Debt or Senior Debt other than the Notes, whether now
         outstanding or issued in the future, including, without limitation,
         the repurchase options contained in the Section 1010 and Article
         Fourteen of the Indenture dated as of November 27, 1995 between the
         Company and First Interstate Bank of Texas, National Association,
         issued with respect to the Company's 8% Convertible Subordinated
         Debentures Due 2005.

         9.      The Notes shall not be convertible into shares of capital 
stock or exchangeable for other securities.

         10.     The Trustee shall be the Security Registrar and Paying Agent 
for the Notes.

         11.     Neither the amount of principal of, nor any premium or 
interest on, any Notes shall be determined by reference to an index or pursuant
to a formula.

         12.     In addition to the covenants set forth in the Master 
Indenture, the Notes shall be subject to the following restrictive covenants:

                 (a)      In addition to those terms defined in the Master
         Indenture, the following terms shall have the meanings assigned when
         used in connection with the Notes:

                 The term "Acquired Indebtedness" means indebtedness of a
         Person existing at the time such Person becomes a Subsidiary of the
         Company or assumed in connection with the acquisition by the Company
         or a Subsidiary of the Company of assets from such Person, and not
         incurred in connection with, or in anticipation of, such Person
         becoming a Subsidiary of the Company or such acquisition.

                 The term "Consolidated Net Worth" means the excess, as
         determined in accordance with GAAP, after appropriate deduction for
         minority interests in the net worth of consolidated subsidiaries, of
         the Company's assets over its liabilities.

                 The term "Senior Recourse Debt" means Senior Debt minus any
         Funded Debt of the Company or any of its Subsidiaries that is (A)(i)
         specifically advanced to finance the acquisition of assets classified
         on the Company's balance sheet as "assets held for sale" and (ii)
         either (a) secured by the assets to which such indebtedness relates
         without recourse to the Company or any of its Subsidiaries or (b)
         issued under a loan agreement that requires each advance to be repaid
         upon sale of the assets to which such advance relates within no more
         than one year from the date of such advance or (B) advanced to a
         Subsidiary or group of Subsidiaries formed for the sole purpose of
         acquiring or holding a portfolio of assets (i) against which a loan is
         obtained that is made without recourse to, and with no
         cross-collateralization against the assets of, the Company or any
         other Subsidiary, and (ii) upon complete or partial liquidation of
         which the loan must be correspondingly completely or partially repaid,
         as the case may be.





                                       5
<PAGE>   6
                 The term "Subordinated Debt" means all Funded Debt except 
Senior Debt.

                 (b)      The Company will not itself, and will not permit any
         Subsidiary to, create, incur, issue, assume, guarantee or become
         liable with respect to any Senior Recourse Debt if, immediately after
         giving effect thereto, the aggregate amount of all Senior Recourse
         Debt then outstanding would exceed 450% of the Company's Consolidated
         Net Worth.

                 (c)      The Company shall not (i) declare or pay any
         dividend, either in cash or property, on any shares of its capital
         stock (except dividends or other distributions payable solely in
         shares of capital stock of the Company), (ii) purchase, redeem or
         retire any shares of its capital stock or any warrants, rights or
         options to purchase or acquire any shares of its capital stock or
         (iii) make any other payment or distribution, either directly or
         indirectly through any Subsidiary, in respect of the Company's capital
         stock (such dividends, purchases, redemptions, retirements, payments
         and distributions being herein collectively called "Restricted
         Payments") if, after giving effect thereto,

                 (1)      an Event of Default under the Master Indenture would 
                          have occurred; or

                 (2)      (A) the sum of (i) such Restricted Payments plus (ii)
                          the aggregate amount of all Restricted Payments made
                          during the period after December 31, 1995 would
                          exceed (B) the sum of (i) $10 million plus (ii) 50%
                          of the Company's Consolidated Net Income for each
                          fiscal year commencing subsequent to December 31,
                          1995 (with 100% reduction for a loss in any fiscal
                          year), plus (iii) the cumulative net proceeds
                          received by the Company from the issuance or sale
                          after December 31, 1995 of capital stock of the
                          Company (including in such net proceeds the face
                          amount of any indebtedness that has been converted
                          into common stock of the Company after December 31,
                          1995).

         Notwithstanding the foregoing, the Company may  make  a
         previously-declared Restricted Payment if the declaration of such
         Restricted Payment was permitted under this paragraph 12(c) when made.
         For purposes of this paragraph 12(c), the amount of any Restricted
         Payment payable in property shall be deemed to be the fair market
         value of such property as determined by the Board of Directors of the
         Company.

                 (d)      The Company shall not and shall not permit any
         Subsidiary of the Company to, create or otherwise cause to become
         effective any consensual encumbrance or restriction of any kind on the
         ability of any Subsidiary of the Company to (a) pay dividends or make
         any other distribution on its capital stock, (b) pay any indebtedness
         owed to the Company or any other Subsidiary of the Company or (c) make
         loans, advances, or capital contributions to the Company or any other
         Subsidiary of the Company except (i) as set forth in the instrument
         evidencing or the agreement governing

         Subsidiary of the Company, provided, that any restriction or
         encumbrance under such instrument or agreement existed at the time of
         acquisition, was not put in place in anticipation of such acquisition,
         and is not applicable to any Person, other than the Person or property
         or assets of the Person so acquired; (ii) by agreements and
         transactions permitted under paragraph 12(c); (iii) customary
         provisions restricting subletting or assignment of any lease or
         license of the Company or any Subsidiary of the Company; (iv) any

         imposed pursuant to an agreement that has been entered into for the
         sale or disposition of the stock, business, assets or properties of
         such Subsidiary; (vii) any encumbrance or restriction arising under
         the terms of purchase money obligations, but only to the extent such
         purchase money obligations restrict or prohibit the transfer of the
         property so acquired; (viii) any encumbrance or restriction arising
         under customary non-assignment provisions in installment purchase
         contracts; (ix) any encumbrance or restriction on the ability of any
         Subsidiary to transfer any of its property acquired after the date
         hereof to the Company or any Subsidiary that is required by a lender
         to, or purchaser of any indebtedness of, such Subsidiary in connection
         with a financing of the acquisition of such property (including with
         respect to the purchase of asset portfolios and pursuant to the
         underwriting or origination of mortgage loans) by such Subsidiary; and
         (x) any encumbrance or restriction pursuant to any agreement that
         extends, refinances, renews or replaces any agreement described in the
         foregoing clauses (i) through (ix).

                 (e)      The Company shall not, and shall not permit any of
         its Material Subsidiaries to, enter into any transaction (or series of
         related transactions), including, without limitation, any loan,
         advance, guarantee or capital contribution to, or for the benefit of,
         or any sale, purchase, lease, exchange or other disposition of any
         property or the rendering of any service, or any other direct or
         indirect payment, transfer or other disposition (a "Transaction"),
         involving payments in excess of $60,000, with any Affiliate of the
         Company (other than a wholly-owned Subsidiary), on terms and
         conditions less favorable to the Company or such Material Subsidiary,
         as the case may be, than would be available at such time in a
         comparable Transaction in arm's length dealings with an unrelated
         Person as determined by the Board of Directors, such approval to be
         evidenced by a Board Resolution.

                 The provisions of the immediately preceding paragraph will not
         apply to:

                          (1)     Restricted Payments otherwise permitted

         Unless this certificate is presented by an authorized representative
of The Depository Trust Company, a New York corporation ("DTC"), to the Company
(as defined below) or its agent for registration of transfer, exchange or
payment, and any certificate issued is registered in the name of Cede & Co. or
in such other name as requested by an authorized representative of DTC (and any
payment 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.

         This Note is a Global Security within the meaning of the Indenture
hereinafter referred to and is registered in the name of Cede & Co, as a
nominee for DTC.  This Note is exchangeable for Notes registered in the name of
a Person other than DTC or its nominee only in the limited circumstances
described in the Indenture, and no transfer of this Note (other than a transfer
of this Note as a whole by DTC to a nominee of DTC or by any nominee of DTC to
DTC or another nominee of DTC) may be registered except in such limited
circumstances.

         AMRESCO, INC., a corporation duly organized and existing under the
laws of Delaware (herein called the "Company", which term includes any
successor Person under the Indenture (as such term is defined on the reverse
hereof)), for value received, hereby promises to pay to Cede & Co., or
registered assigns, the principal sum of Fifty Seven Million Five Hundred
Dollars ($57,500,000) on July 1, 1999, and to pay interest thereon on the 15th
day of each month, or, if such day is not a Business Day, the next succeeding
Business Day (each an "Interest Payment Date"), based on a 360-day year of
twelve 30-day months, from July 19, 1996, or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, commencing
September 15, 1996, at the rate of 8.75% per annum, until the principal hereof
is paid or made available for payment.  The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Note is registered at
the close of business on the tenth day of the month (whether or not a Business
Day) in the same month as the relevant Interest Payment Date. Any interest on
this Note that is not so punctually paid or duly provided for will forthwith
cease to be payable to the Holder on such date and may either be paid to the
Person in whose name this Note (or one or more Predecessor Notes) is registered
at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to
holders of the Notes not less than 10 days prior to such Special Record Date,
or be paid at any

time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.

         Payment of the principal of (and premium, if any) and any interest due
on this Note will be made at the office or agency of the Company maintained for
that purpose in same day funds, in the City of Detroit, Michigan or New York,
New York in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts.  So
long as DTC or its nominee, Cede & Co., is the sole registered owner and the
sole Holder of the Global Security for all purposes under the Indenture, such
payments will be made by the Trustee directly to DTC or to such nominee.

         Reference is hereby made to the further provisions of this Note set
forth below, which further provisions shall for all purposes have the same
effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee referred to below by manual signature, this Note
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                     Senior Note, Series 1996-A due 1999


         This Note is one of a duly authorized issue of securities of the
Company (the "Securities") issued and to be issued in one or more series under
a Senior Notes Indenture dated as of July 1, 1996, between the Company and
Comerica Bank, as Trustee (the "Trustee," which term includes any successor
trustee under the Senior Notes Indenture), as supplemented by an Officers'
Certificate and Company Order dated as of July 19, 1996, pursuant to such
Senior Notes Indenture establishing the Notes (such Senior Notes Indenture, as
supplemented by such Officer's Certificate and Company Order, being herein
called the "Indenture"), to which Indenture reference is hereby made for a
statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Notes
and of the terms upon which the Notes are, and are to be, authenticated and
delivered.  This Security is one of the series designated as Senior Notes,
Series 1996-A due 1999 (the "'Notes"), limited in aggregate principal amount to
$57,500,000.  By the terms of the Indenture, additional Securities of other
separate series, which may vary as to date, amount, Stated Maturity, interest
rate or method of calculating the interest rate and in other respects as
therein provided, may be issued in an unlimited principal amount.

         As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Note of this series will have any right to institute any
proceeding, judicial or otherwise, with respect to the Indenture, or for the
appointment of a receiver or trustee, or for any other remedy under the
Indenture, unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to the Notes, the
Holders of not less than 25% in principal amount of the Outstanding Notes of
this series shall have made written request to the Trustee to institute
proceedings in its own name as Trustee, furnished the Trustee reasonable
indemnity, and within 60 days the Trustee shall not have received from the
Holders of a majority in principal amount of the Outstanding Notes a direction
inconsistent with such request and shall have failed to institute such
proceeding; provided, however, that such limitations do not apply to a suit
instituted by the Holder hereof for the enforcement of payment of the principal
of (and premium, if any) and interest on this Note on or after the respective
due dates expressed herein.

         The Notes are not subject to redemption by the Company at the option 
of the Company.

         In accordance with the terms of the Indenture, upon the occurrence of
a Repurchase Event, the Holder of this Note shall have the right, at such
Holder's option, to require the Company to purchase, and upon exercise of such
right, the Company shall purchase, all or any part of this Note on the date
that is 30 days after the date the Company gives notice of the Repurchase Event
at a price equal to 100% of the principal amount thereof, together with accrued
and unpaid interest.

         In the event of transfer or exchange, a new Note or Notes of like
tenor and for a like aggregate principal amount will be issued to the Holder,
in the case of exchange, or the designated transferee or transferees, in the
case of transfer.





                                      A-4
<PAGE>   14
         If an Event of Default with respect to Notes shall occur and be
continuing, the principal of the Notes may (subject to the conditions set forth
in the Indenture and in the Officer's Certificate and Company Order) be
declared due and payable in the manner and with the effect provided in the
Indenture.

         The Indenture contains provisions for defeasance at any time of the
Company's obligations in respect of (i) the entire indebtedness of this Note or
(ii) certain restrictive covenants with respect to this Note, in each case upon
compliance with certain conditions set forth therein.

         The Indenture permits, with exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of not less than a majority in aggregate principal
amount of the Securities at the time Outstanding of each series to be affected
and, for certain purposes, without the consent of the Holders of any Securities
at the time Outstanding.  The Indenture also contains provisions permitting the
Holders of specified percentages in aggregate principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of
all Securities of such series, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequence.  Any such consent or waiver by the Holder of this Note shall
bind such Holder and every future Holder of this Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

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

         The Notes are issuable only in registered form, without coupons, in
denominations of $1,000 and any amount in excess thereof which is an integral
multiple of $1,000.  As described in the Indenture, the Notes may be issued as
book- entry notes in the form of one fully registered Global Security bearing
the legend specified in the Indenture regarding certain restrictions on
registration of transfer and exchange, deposited with, or on behalf of, DTC,
and registered in the name of DTC's nominee.  As provided in the Indenture, and
subject to certain limitations (including additional limitations in the event
that this Note is a Global Security) therein set forth, Notes are exchangeable
for a like aggregate principal amount of Notes and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same.

         As provided in the Indenture and subject to certain limitations
therein set forth (including additional limitations in the event that this Note
is a Global Security), the transfer of this Note is registrable in the Security
Register, upon surrender of this Note for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest on Note are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the





                                      A-5
<PAGE>   15
Holder hereof or such Holder's attorney duly authorized in writing and
thereupon one or more new Notes of like tenor of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

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

         Prior to due presentment of this Note for registration of transfer,
