Ladies and Gentlemen:

     From time to time Micron Technology, Inc., a Delaware corporation (the
"Company"), proposes to enter into one or more Pricing Agreements (each a
"Pricing Agreement") in the form of Annex I hereto, with such additions and
deletions as the parties thereto may determine, and, subject to the terms and
conditions stated herein and therein, to issue and sell to the firms named in
Schedule I to the applicable Pricing Agreement (such firms constituting the
"Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of its convertible debt securities (the
"Securities"), convertible into Common Stock, par value $0.10 per share, of the
Company (the "Common Stock"), specified in Schedule II to such Pricing Agreement
(with respect to such Pricing Agreement, the "Firm Securities").  If specified
in such Pricing Agreement, the Company may grant to the Underwriters the right
to purchase at their election an additional number of Securities, specified in
such Pricing Agreement as provided in Section 3 hereof (the "Optional
Securities"). The Firm Securities and the Optional Securities, if any, which the
Underwriters elect to purchase pursuant to Section 3 hereof are herein
collectively called the "Designated Securities."

     The terms and rights of any particular issuance of Designated Securities
shall be as specified in the Pricing Agreement relating thereto and in or
pursuant to the indenture (the "Indenture") identified in such Pricing
Agreement.

     1.   Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Securities, for whom the firms designated as
representatives of the Underwriters of such Securities in the Pricing Agreement
relating thereto will act as representatives (the "Representatives"). The term
"Representatives" also refers to a single firm acting as sole representative of
the Underwriters and to an Underwriter or Underwriters who act without any firm
being designated as its or their representatives. This Underwriting Agreement
shall not be construed as an obligation of the Company to sell any of the
Securities or as an obligation of any of the Underwriters to purchase the
Securities. The obligation of the Company to issue and sell any of the
Securities and the obligation of any of the Underwriters to purchase any of the
Securities shall be evidenced by the Pricing Agreement with respect to the
Designated Securities specified therein. Each Pricing Agreement shall specify
the aggregate principal amount of such Firm Securities, the maximum 
<PAGE>
 
aggregate principal amount of Optional Securities, if any, the initial public
offering price of such Firm Securities and Optional Securities or the manner of
determining such price, the purchase price to the Underwriters of such
Designated Securities, the names of the Underwriters of such Designated
Securities, the names of the Representatives of such Underwriters and the
principal amount of such Designated Securities to be purchased by each
Underwriter and shall set forth the date, time and manner of delivery of such
Firm Securities and Optional Securities, if any, and payment therefor. The
Pricing Agreement shall also specify (to the extent not set forth in the
Indenture and the registration statement and prospectus with respect thereto)
the terms of such Designated Securities. A Pricing Agreement shall be in the
form of an executed writing (which may be in counterparts), and may be evidenced
by an exchange of telegraphic communications or any other rapid transmission
device designed to produce a written record of communications transmitted. The
obligations of the Underwriters under this Agreement and each Pricing Agreement
shall be several and not joint.

     2.   The Company represents and warrants to, and agrees with, each of the
Underwriters that:

          (a) A registration statement on Form S-3 (File No. 333-18441) (the
"Initial Registration Statement") in respect of the Securities and the shares of
Common Stock issuable upon conversion thereof has been filed with the Securities
and Exchange Commission (the "Commission"); the Initial Registration Statement
and any post-effective amendment thereto, each in the form heretofore delivered
or to be delivered to the Representatives and, excluding exhibits to the Initial
Registration Statement, but including all documents incorporated by reference in
the prospectus contained therein, to the Representatives for each of the other
Underwriters, have been declared effective by the Commission in such form; no
other document with respect to the Initial Registration Statement or document
incorporated by reference therein has heretofore been filed or transmitted for
filing with the Commission other than a registration statement, if any,
increasing the size of the offering (a "Rule 462(b) Registration Statement"),
filed pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the
"Act"), which became effective upon filing (and other than prospectuses filed
pursuant to Rule 424(b) of the rules and regulations of the Commission under the
Act, each in the form heretofore delivered to the Representatives); and no stop
order suspending the effectiveness of the Initial Registration Statement, any
post-effective amendment thereto or the Rule 462(b) Registration Statement, if
any, has been issued and no proceeding for that purpose has been initiated or
threatened by the Commission (any preliminary prospectus included in such
registration statement or filed with the Commission pursuant to Rule 424(a)
under the Act, is hereinafter called a "Preliminary Prospectus;" the various
parts of the Initial Registration Statement and the Rule 462(b) Registration
Statement, if any, including all exhibits thereto and the documents incorporated
by reference in the prospectus contained in the Initial Registration Statement
at the time such part of the Initial Registration Statement became effective or
such part of the Rule 462(b) Registration Statement, if any, became or hereafter
becomes effective, but excluding Form T-1, each as amended at the time such part
of the registration statement became effective, are hereinafter collectively
called the "Registration Statement;" the prospectus relating to the Securities,
in the form in which it has most recently been filed, or transmitted for filing,
with the Commission on or prior to the date of this Agreement, being hereinafter
called the "Prospectus;" any reference herein to any Preliminary Prospectus or
the Prospectus shall be deemed to refer to and include the documents
incorporated by reference therein pursuant to the applicable form under the Act,
as of the date of such Preliminary Prospectus or Prospectus, as the case may be;
any reference to any amendment or supplement to any Preliminary Prospectus or
the Prospectus shall be deemed to refer to and include any documents filed after
the date of such Preliminary Prospectus or Prospectus, as the case may be, under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
incorporated by reference in such Preliminary Prospectus or Prospectus, as the
case may be; any reference to any amendment to the Registration Statement shall
be deemed to refer to and include any annual report of the Company filed
pursuant to Sections 13(a) or 15(d) of the Exchange Act after the effective date
of the Registration Statement that is incorporated by reference in the
Registration Statement; and any reference to the Prospectus as amended or
supplemented shall

                                      -2-
<PAGE>
 
be deemed to refer to the Prospectus as amended or supplemented in relation to
the applicable Designated Securities in the form in which it is filed with the
Commission pursuant to Rule 424(b) under the Act in accordance with Section 5(a)
hereof, including any documents incorporated by reference therein as of the date
of such filing);

          (b) 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
further 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 any
statements or omissions made in reliance upon and in conformity with information
furnished in writing to the Company by an Underwriter of Designated Securities
through the Representatives expressly for use in the Prospectus as amended or
supplemented relating to such Securities;

          (c) The Registration Statement and the Prospectus conform, and any
further amendments or supplements to the Registration Statement or the
Prospectus will conform, in all material respects to the requirements of the Act
and the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act") and
the rules and regulations of the Commission thereunder and do not and will not,
as of the applicable effective date as to the Registration Statement and any
amendment thereto and as of the applicable filing date as to the Prospectus and
any amendment or supplement thereto, 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 any statements or omissions made
in reliance upon and in conformity with information furnished in writing to the
Company by an Underwriter of Designated Securities through the Representatives
expressly for use in the Prospectus as amended or supplemented relating to such
Securities;

          (d) Neither the Company nor any of its subsidiaries has sustained
since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus any material loss or interference
with its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree, otherwise than as set forth or contemplated in the Prospectus;
and, since the respective dates as of which information is given in the
Registration Statement and the Prospectus, there has not been any material
change in the capital stock or long-term debt of the Company or any of its
subsidiaries or any material adverse change, or any development that would
reasonably be expected to cause a prospective material adverse change, in the
general affairs, management, financial position, shareholders' equity or results
of operations of the Company and its subsidiaries, otherwise than as set forth
or contemplated in the Prospectus;

          (e) Each of the Company and Micron Electronics, Inc. ("MEI") has been
duly incorporated and is validly existing as a corporation in good standing
under the laws of the state of its incorporation, with power and authority
(corporate and other) to own its properties and conduct its business as
described in the Prospectus;

                                      -3-
<PAGE>
 
          (f) The Company has an authorized capitalization as set forth in the
Prospectus, and all of the issued shares of capital stock of the Company have
been duly and validly authorized and issued and are fully paid and non-
assessable; the shares of Common Stock initially issuable upon conversion of the
Securities (the "Conversion Shares") have been duly and validly authorized and
reserved for issuance and, when issued and delivered in accordance with the
provisions of the Securities and the Indenture, will be duly and validly issued,
fully paid and non-assessable and will conform to the description of the Common
Stock contained in the Prospectus;

          (g) When the Firm Securities are issued and delivered pursuant to this
Agreement and the Pricing Agreement with respect to such Designated Securities,
and in the case of any Optional Securities, pursuant to the Over-allotment
Options (as defined in Section 3 hereof) with respect to such Securities, such
Designated Securities will have been duly authorized, executed, authenticated,
issued and delivered and will constitute valid and legally binding obligations
of the Company entitled to the benefits provided by the Indenture, which will be
substantially in the form filed as an exhibit to the Registration Statement; the
Indenture has been duly authorized and duly qualified under the Trust Indenture
Act and, at the Time of Delivery for such Designated Securities (as defined in
Section 4 hereof), the Indenture will constitute a valid and legally binding
instrument, enforceable against the Company in accordance with its terms,
subject, as to enforcement, to bankruptcy, insolvency, reorganization and other
laws of general applicability relating to or affecting creditors' rights and to
general equity principles; and the Indenture conforms and the Designated
Securities will conform in all material respects to the descriptions thereof
contained in the Prospectus as amended or supplemented with respect to such
Designated Securities;

          (h) The issue and sale of the Securities, the issuance of the
Conversion Shares and the compliance by the Company with its obligations
pursuant to the Securities, the Indenture, this Agreement, any Pricing Agreement
and each Over-allotment Option, if any, will not result in a breach or violation
of any of the terms or provisions of, or constitute a default under, any
indenture, mortgage, deed of trust, loan agreement (other than as disclosed in
the Prospectus) or other agreement or instrument to which the Company or MEI is
a party or by which the Company or MEI is bound or to which any of the property
or assets of the Company or MEI is subject, nor will such action result in any
violation of any statute or any order, rule or regulation of any court or
governmental agency or body having jurisdiction over the Company or MEI or any
of their properties, except where such breach, violation or default would not
have a material adverse effect on the Company's business and results of
operations, nor will such action result in any violation of the provisions of
the Certificate of Incorporation or By-laws of the Company or MEI; and no
consent, approval, authorization, order, registration or qualification of or
with any such court or governmental agency or body is required for the issue and
sale of the Securities or the performance by the Company of its obligations
pursuant to this Agreement or any Pricing Agreement or the Indenture or any
Over-allotment Option, except (i) such as have been, or will have been prior to
the Time of Delivery, obtained under the Act and the Trust Indenture Act, (ii)
the approval of the listing of the Conversion Shares on the New York Stock
Exchange and (iii) such consents, approvals, authorizations, registrations or
qualifications as may be required under state securities or Blue Sky laws in
connection with the purchase and distribution of the Securities by the
Underwriters and except where the failure to obtain such consents would not have
a material adverse effect on the offering of the Designated Securities;

          (i) The statements set forth in the Prospectus under the captions
"Description of Securities", "Description of Notes" and "Description of Capital
Stock", insofar as they purport to constitute a summary of the terms of the
Designated Securities and the Common Stock, and under the captions "Certain
Federal Income Tax Considerations", "Underwriting" and "Plan of Distribution",
insofar as they purport to 

                                      -4-
<PAGE>
 
summarize certain provisions of the laws and documents referred to therein,
fairly summarize such terms, laws and documents in all material respects;

          (j) Neither the Company nor any of its subsidiaries is in violation of
its Certificate of Incorporation or By-laws or, in any material respect, in
default in the performance or observance of any obligation, agreement, covenant
or condition contained in any indenture, mortgage, deed of trust, loan
agreement, lease or other agreement or instrument to which it is a party or by
which it or any of its properties may be bound;

          (k) Other than as set forth in the Prospectus, there are no legal or
governmental proceedings pending to which the Company or any of its subsidiaries
is a party or of which any property of the Company or any of its subsidiaries is
the subject which, if determined adversely to the Company or any of its
subsidiaries, would individually or in the aggregate, have a material adverse
effect on the current or future consolidated financial position, shareholders'
equity or results of operations of the Company and its subsidiaries; and, to the
best of the Company's knowledge, no such proceedings are threatened by
governmental authorities or by others;

          (l) The Company is not and, after giving effect to the offering and
sale of the Securities, will not be an "investment company" or an entity
"controlled" by an "investment company," as such terms are defined in the
Investment Company Act of 1940, as amended (the "Investment Company Act");

          (m) Coopers & Lybrand, L.L.P., who have certified certain financial
statements of the Company and its subsidiaries, are independent public
accountants as required by the Act and the rules and regulations of the
Commission thereunder;

          (n) The Company and its subsidiaries own or possess or can acquire on
commercially reasonable terms adequate licenses or other rights to use all
patents, trademarks, service marks, trade names, copyrights, mask work rights,
technology and know-how necessary to conduct the business now or proposed to be
conducted by the Company and its subsidiaries as described in the Prospectus,
and except as disclosed in the Prospectus, the Company has not received any
notice of infringement of or conflict with (and knows of no such infringement of
or conflict with) asserted rights of others with respect to any patents,
trademarks, service marks, trade names, copyrights, mask work rights or know-how
which would be reasonably likely to result in any material adverse effect upon
the Company and its subsidiaries; and

          (o) The Company and its subsidiaries have obtained any permits,
consents and authorizations required to be obtained by them under laws or
regulations relating to the protection of the environment or concerning the
handling, storage, disposal or discharge of toxic materials (collectively
"Environmental Laws"), and any such permits, consents and authorizations remain
in full force and effect. The Company and its subsidiaries are in compliance
with the Environmental Laws in all material respects, and there is no pending
or, to the Company's knowledge, threatened, action or proceeding against the
Company and its subsidiaries alleging violations of the Environmental laws.

     3.   Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
such Designated Securities, the several Underwriters propose to offer such
Designated Securities for sale upon the terms and conditions set forth in the
Prospectus as amended or supplemented.

                                      -5-
<PAGE>
 
     The Company may specify in the Pricing Agreement applicable to any
Designated Securities that the Company thereby grants to the Underwriters the
right (an "Over-allotment Option") to purchase at their election up to the
principal amount of Optional Securities set forth in such Pricing Agreement, on
the terms set forth in the paragraph above, for the sole purpose of covering
over-allotments in the sale of the Firm Securities.  Any such election to
purchase Optional Securities may be exercised by written notice from the
Representatives to the Company given within a period specified in the Pricing
Agreement, setting forth the aggregate principal amount of Optional Securities
to be purchased and the date on which such Optional Securities are to be
delivered, as determined by the Representatives but in no event earlier than the
First Time of Delivery (as defined in Section 4 hereof) or, unless the
Representatives and the Company otherwise agree in writing, earlier than or
later than the respective number of days after the date of such notice set forth
in such Pricing Agreement.

     The principal amount of Optional Securities to be added to the principal
amount of Firm Securities to be purchased by each Underwriter as set forth in
Schedule I to the Pricing Agreement applicable to such Designated Securities
shall be, in each case, the principal amount of Optional Securities which the
Company has been advised by the Representatives have been attributed to such
Underwriter; provided that, if the Company has not been so advised, the

and date for delivery is herein called a "Time of Delivery."

Representatives promptly of any such amendment or supplement after such Time of
Delivery and furnish the Representatives with copies thereof; to file promptly

required in connection with the offering or sale of such Securities, and during
such same period to advise the Representatives, promptly after it receives
notice thereof, of the time when any amendment to the Registration Statement has

Commission of any stop order or of any order preventing or suspending the use of
any prospectus relating to the Securities, of the suspension of the

Conversion Shares and if at such time any event shall have occurred as a result
of which the Prospectus as then amended or supplemented would include an untrue
statement of a material fact or omit to state any material fact necessary in

          (e) During the period beginning from the date of the Pricing Agreement

the Prospectus as amended or supplemented;

              (iii) The Conversion Shares (based on the initial conversion rate)

Indenture, will be duly and validly issued and fully paid and non-assessable,
and will conform in all material respects to the description of the Common Stock
contained in the Prospectus;

              (iv)  The Indenture has been duly authorized, executed and

may be required under state securities or Blue Sky laws in connection with the
purchase and distribution of the Designated Securities by the Underwriters;

              (vi)  The statements set forth in the Prospectus under the
captions "Description of Securities," "Description of Notes" and "Description of
Capital Stock," insofar as they purport to constitute a summary of the terms of
the Designated Securities and the Common Stock, fairly summarize such terms in
all material respects; and under the captions "Underwriting" and "Plan of
Distribution", insofar as they purport to summarize certain provisions of the
laws and documents referred to therein, fairly summarize such terms, laws and
document in all material respects;

              (vii) The statements set forth in the Prospectus under the caption
"Certain Federal Income Tax Considerations", insofar as they purport to describe

"investment company" or an entity "controlled" by an "investment company," as
such terms are defined in the Investment Company Act;

              (ix)  The documents incorporated by reference in the Prospectus as
amended or supplemented (other than the financial statements and related
schedules therein, as to which such counsel need express no opinion), when they
became effective or were filed with the Commission, as the case may be, complied
as to form in all material respects with the requirements of the Act or the
Exchange Act, as applicable, and the rules and regulations of the Commission
thereunder; and

              (x)   The Registration Statement and the Prospectus as amended or

Indenture Act and the rules and regulations thereunder.

     Such counsel shall also include a statement to the effect that, although
such counsel does not assume any responsibility for the accuracy, completeness
or fairness of the statements contained in the Registration Statement or the
Prospectus, except for those referred to in the opinion in subsection (v) of
this Section 7(c), such counsel has no reason to believe that, as of its
effective date, the Registration Statement or any further amendment thereto made
by the Company prior to the Time of Delivery (other than the financial
statements and related schedules therein and financial data derived therefrom,
as to which such counsel need express no belief) 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, as
of its date, the Prospectus as amended or supplemented or any further amendment
or supplement thereto made by the Company prior to the Time of Delivery (other
than the financial statements and related schedules therein and financial data
derived therefrom, as to which such counsel need express no belief) contained an
untrue statement of a material fact or omitted to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or that, as of the Time of Delivery,
either the Registration Statement or the Prospectus as amended or supplemented
or any further amendment or supplement thereto made by the Company prior to the
Time of Delivery (other than the financial statements and related schedules
therein and financial data derived therefrom, as to which such counsel need
express no belief) contains an untrue statement 

                                      -10-
<PAGE>
 
of a material fact or omits to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

     In rendering the opinions set forth herein, such counsel may rely with
respect to matters of fact upon certificates of officers of the Company,
provided that such counsel shall state that they have no reason to believe both
you and they are not justified in relying upon such certificates and a copy of
such certificate shall be delivered to you. Such counsel's opinion that any
agreement is valid, binding or enforceable in accordance with its terms may be
qualified as to: (1) limitations imposed by bankruptcy, insolvency,
reorganization, arrangement, fraudulent conveyance, moratorium or other laws
relating to or affecting the rights of creditors generally; (2) rights to
indemnification and contribution which may be limited by applicable law or
equitable principles; and (3) general principles of equity, including without
limitation concepts of materiality, reasonableness, good faith and fair dealing,
and the possible unavailability of specific performance or injunctive relief,
regardless of whether such validity and binding effect are considered in a
proceeding in equity or at law.

          (d) Roderic W. Lewis, the Company's General Counsel, shall have
furnished to you his written opinion, dated each Time of Delivery for such
Designated Securities, in form and substance reasonably satisfactory to you, to
the effect that:

              (i)   Each of the Company and MEI has been duly incorporated and
is validly existing as a corporation in good standing under the laws of the
state of its incorporation with power and authority (corporate and other) to own
its properties and conduct its business as described in the Prospectus as
amended or supplemented;

              (ii)  The Company has an authorized capitalization as set forth in
the Prospectus as amended or supplemented, and all of the issued shares of
capital stock of the Company have been duly and validly authorized and issued
and are fully paid and non-assessable;

              (iii) To such counsel's knowledge and other than as set forth in
the Prospectus, there are no legal or governmental proceedings pending to which
the Company or any of its subsidiaries is a party or of which any property of
the Company or any of its subsidiaries is the subject which, if determined
adversely to the Company or any of its subsidiaries, would individually have a
material adverse effect on the consolidated financial position, shareholders'
equity or results of operations of the Company and its subsidiaries, taken as a
whole;

              (iv)  The issue and sale of the Designated Securities, the
issuance of the Conversion Shares and the performance by the Company of its
obligations pursuant to the Designated Securities, the Indenture, this Agreement
and the Pricing Agreement with respect to the Designated Securities will not
result in a breach or violation of any of the terms or provisions of, or
constitute a default under, any indenture, mortgage, deed of trust, loan
agreement (other than as disclosed in the Prospectus) or other agreement or
instrument filed as an exhibit to the Registration Statement or to the Company's
most recent Annual Report on Form 10-K, nor will such actions result in any
violation of the provisions of the Certificate of Incorporation or By-laws of
the Company or, to such counsel's knowledge, any statute, order, rule or
regulation of any court or governmental agency or body having jurisdiction over
the Company or any of its properties; and

              (v)   Such counsel does not know of any contracts or other
documents of a character required to be filed as an exhibit to the Registration
Statement or required to be incorporated by 

                                      -11-
<PAGE>
 
reference into the Prospectus as amended or supplemented or required to be
described in the Registration Statement or the Prospectus as amended or
supplemented which are not filed or incorporated by reference or described as
required.

     Such counsel shall also include a statement to the effect that, although
such counsel does not assume any responsibility for the accuracy, completeness
or fairness of the statements contained in the Registration Statement or the
Prospectus, such counsel has no reason to believe that, as of its effective
date, the Registration Statement or any further amendment thereto made by the
Company prior to the Time of Delivery (other than the financial statements and
related schedules therein and financial data derived therefrom, as to which such
counsel need express no belief) 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, as of its date, the
Prospectus as amended or supplemented or any further amendment or supplement
thereto made by the Company prior to the Time of Delivery (other than the
financial statements and related schedules therein and financial data derived
therefrom, as to which such counsel need express no belief) contained an untrue
statement of a material fact or omitted to state a material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading or that, as of the Time of Delivery, either the
Registration Statement or the Prospectus as amended or supplemented or any
further amendment or supplement thereto made by the Company prior to the Time of
Delivery (other than the financial statements and related schedules therein and
financial data derived therefrom, as to which such counsel need express no
belief) contains an untrue statement of a material fact or omits to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (e) On the date of the Pricing Agreement for such Designated
Securities at a time prior to the execution of the Pricing Agreement with
respect to such Designated Securities and at each Time of Delivery for such
Designated Securities, the independent accountants of the Company who have
certified the financial statements of the Company and its subsidiaries included
or incorporated by reference in the Registration Statement shall have furnished
to the Representatives a letter, dated the effective date of the Registration
Statement or the date of the most recent report filed with the Commission
containing financial statements and incorporated by reference in the
Registration Statement, if the date of such report is later than such effective
date, and a letter dated such Time of Delivery, respectively, to the effect set
forth in Annex I hereto, and with respect to such letter dated such Time of
Delivery, as to such other matters as the Representatives may reasonably request
and in form and substance satisfactory to the Representatives (the executed copy
of the letter delivered prior to the execution of the Pricing Agreement is
attached as Annex I(a) hereto and a draft of the form of letter to be delivered
on the effective date of any post-effective amendment to the Registration
Statement and as of each Time of Delivery is attached as Annex I(b) hereto);

          (f)  (i)  Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included or
incorporated by reference in the Prospectus as amended prior to the date of the
Pricing Agreement relating to the Designated Securities any loss or interference
with its business from fire, explosion, flood or other calamity, whether or not
covered by insurance, or from any labor dispute or court or governmental action,
order or decree, otherwise than as set forth or contemplated in the Prospectus
as amended prior to the date of the Pricing Agreement relating to the Designated
Securities, and (ii) since the respective dates as of which information is given
in the Prospectus as amended prior to the date of the Pricing Agreement relating
to the Designated Securities there shall not have been any change in the capital
stock or long-term debt of the Company or any of its subsidiaries or any change
or any development that would reasonably be expected to cause a prospective
change, in the general affairs, management, financial position, shareholders'
equity or results of operations of the Company and its subsidiaries, otherwise
than as set forth or contemplated in the Prospectus as amended prior to the date
of the 

                                      -12-
<PAGE>
 
Pricing Agreement relating to the Designated Securities, the effect of which, in
any such case described in Clause (i) or (ii), is in the reasonable judgment of
the Representatives so material and adverse as to make it impracticable or
inadvisable to proceed with the public offering or the delivery of the Firm
Securities or Optional Securities or both on the terms and in the manner
contemplated in the Prospectus as first amended or supplemented relating to the
Designated Securities;

          (g) On or after the date of the Pricing Agreement relating to the
Designated Securities (i) no downgrading shall have occurred in the rating
accorded the Company's debt securities or preferred stock by any "nationally
recognized statistical rating organization", as that term is defined by the
Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such
organization shall have publicly announced that it has under surveillance or
review, with possible negative implications, its rating of any of the Company's
debt securities or preferred stock;

          (h) On or after the date of the Pricing Agreement relating to the
Designated Securities there shall not have occurred any of the following: (i) a
suspension or material limitation in trading in securities generally on the New
York Stock Exchange or on the Nasdaq National Market ("Nasdaq"); (ii) a
suspension or material limitation in trading in the Company's securities on the
New York Stock Exchange; (iii) a general moratorium on commercial banking
activities declared by either Federal or New York state authorities; or (iv) the
outbreak or escalation of hostilities involving the United States or the
declaration by the United States of a national emergency or war, if the effect
of any such event specified in this Clause (iv) in the reasonable judgment of
the Representatives makes it impracticable or inadvisable to proceed with the
public offering or the delivery of the Designated Securities on the terms and in
the manner contemplated in the Prospectus as first amended or supplemented
relating to the Designated Securities;

          (i) The Company shall have furnished or caused to be furnished to the
Representatives at each Time of Delivery for the Designated Securities a
certificate or certificates of officers of the Company satisfactory to the
Representatives as to the accuracy of the representations and warranties of the
Company herein at and as of such Time of Delivery, as to the performance by the
Company of all of its obligations hereunder to be performed at or prior to such
Time of Delivery, as to the matters set forth in subsections (a) and (f) of this
Section and as to such other matters as the Representatives may reasonably
request;

          (j) The Company shall have complied with the provisions of Section
5(c) hereof with respect to the furnishing of prospectuses on the New York
Business Day next succeeding the date of the Pricing Agreement; and

          (k) The Company shall have obtained and delivered to the Underwriters
executed copies of an agreement from each officer and director of the Company
listed on Schedule III of the Pricing Agreement substantially to the effect set
forth on Schedule IV of the Pricing Agreement.

     8.   (a)  The Company will 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, 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 any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Securities, or any
amendment or supplement thereto, 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 such Underwriter in connection with investigating or 

                                      -13-
<PAGE>
 
defending any such action or claim as such expenses are incurred; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, any preliminary prospectus supplement, the
Registration Statement, the Prospectus as amended or supplemented and any other
prospectus relating to the Securities, or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter of Designated Securities through the Representatives
expressly for use in the Prospectus as amended or supplemented relating to such
Securities.

          (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, 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 any Preliminary Prospectus, any preliminary prospectus supplement,
the Registration Statement, the Prospectus as amended or supplemented and any
other prospectus relating to the Securities, or any amendment or supplement
thereto, 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 any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Securities, or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives expressly for use therein; and will reimburse the Company for
any legal or other expenses reasonably incurred by the Company in connection
with investigating or defending any such action or claim as such expenses are
incurred.

          (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 commence  ment thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. 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 therein and, to the extent that it shall wish,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified party
(who shall not, except with the consent of the indemnified party, be counsel to
the indemnifying party) and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include any statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party.

          (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages

                                      -14-
<PAGE>
 
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
of the Designated Securities on the other from the offering of the Designated
Securities to which such loss, claim, damage or liability (or action in respect
thereof) relates. If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law or if the indemnified
party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
the Underwriters of the Designated Securities on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and such Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from such offering (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by such Underwriters. 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 on the one hand
or such Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were 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 above in this subsection (d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above in 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
any such action or claim. 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 applicable Designated Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which 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
obligations of the Underwriters of Designated Securities in this subsection (d)
to contribute are several in proportion to their respective underwriting
obligations with respect to such Securities and not joint.

          (e) The obligations of the Company pursuant to this Section 8 shall be
in addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Underwriter within the meaning of the Act; and the obligations of the
Underwriters pursuant to this Section 8 shall be in addition to any liability
which the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of the Company and to
each person, if any, who controls the Company within the meaning of the Act.

     9.   (a)  If any Underwriter shall default in its obligation to purchase
the Firm Securities or the Optional Securities which it has agreed to purchase
under the Pricing Agreement relating to such Designated Securities, the
Representatives may in their discretion arrange for themselves or another party
or other parties to purchase such Designated Securities on the terms contained
herein. If within thirty-six hours after such default by any Underwriter the
Representatives do not arrange for the purchase of such Firm Securities or
Optional Securities, as the case may be, then the Company shall be entitled to a
further period of thirty-six 

                                      -15-
<PAGE>
 
hours within which to procure another party or other parties satisfactory to the
Representatives to purchase such Designated Securities on such terms. In the
event that, within the respective prescribed period, the Representatives notify
the Company that they have so arranged for the purchase of such Designated
Securities, or the Company notifies the Representatives that it has so arranged
for the purchase of such Designated Securities, the Representatives or the
Company shall have the right to postpone the Time of Delivery for such
Designated Securities for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus as amended or supplemented, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments or supplements to the Registration Statement or the Prospectus which
in the reasonable opinion of the Company and the Representatives may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person had
originally been a party to the Pricing Agreement with respect to such Designated
Securities.

          (b) If, after giving effect to any arrangements for the purchase of
the Firm Securities or Optional Securities, as the case may be, of a defaulting
Underwriter or Underwriters by the Representatives and the Company as provided
in subsection (a) above, the aggregate principal amount of such Firm Securities
or Optional Securities, as the case may be, which remains unpurchased does not
exceed one-eleventh of the aggregate principal amount of the Firm Securities or
Optional Securities, as the case may be, then the Company shall have the right
to require each non-defaulting Underwriter to purchase the principal amount of
Firm Securities or Optional Securities, as the case may be, which such
Underwriter agreed to purchase under the Pricing Agreement relating to such Firm
Securities or Optional Securities, as the case may be, and, in addition, to
require each non-defaulting Underwriter to purchase its pro rata share (based on
the principal amount of Firm Securities or Optional Securities, as the case may
be, which such Underwriter agreed to purchase under such Pricing Agreement) of
the Firm Securities or Optional Securities, as the case may be, of such
defaulting Underwriter or Underwriters for which such arrangements have not been
made; but nothing herein shall relieve a defaulting Underwriter from liability
for its default.

          (c) If, after giving effect to any arrangements for the purchase of
the Firm Securities or Optional Securities, as the case may be, of a defaulting
Underwriter or Underwriters by the Representatives and the Company as provided
in subsection (a) above, the aggregate principal amount of Firm Securities or
Optional Securities, as the case may be, which remains unpurchased exceeds one-
eleventh of the aggregate principal amount of the Firm Securities or Optional
Securities, as the case may be, as referred to in subsection (b) above, or if
the Company shall not exercise the right described in subsection (b) above to
require non-defaulting Underwriters to purchase Firm Securities or Optional
Securities, as the case may be, of a defaulting Underwriter or Underwriters,
then the Pricing Agreement relating to such Firm Securities or Optional
Securities, as the case may be, shall thereupon terminate, without liability on
the part of any non-defaulting Underwriter or the Company, except for the
expenses to be borne by the Company and the Underwriters as provided in Section
6 hereof and the indemnity and contribution agreements in Section 8 hereof; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Securities.

                                      -16-
<PAGE>
 
     11.  If any Pricing Agreement or Over-allotment Option shall be terminated
pursuant to Section 9 hereof, or if the Underwriters do not purchase Designated
Securities under the Pricing Agreement or Over-allotment Option relating to such
Designated Securities because the condition set forth in Section 7(b), 7(f),
7(g), 7(h) or 7(i) hereof shall not have been satisfied, the Company shall not
then be under any liability to any Underwriter with respect to the Firm
Securities or Option Securities, as the case may be, covered by such Pricing
Agreement except as provided in Sections 6 and 8 hereof; but, if for any other
reason Designated Securities are not delivered by or on behalf of the Company as
provided herein, the Company will reimburse the Underwriters through the
Representatives for all out-of-pocket expenses approved in writing by the
Representatives, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of such Designated Securities, but the Company shall then be under no
further liability to any Underwriter with respect to such Designated Securities
except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, the Representatives of the Underwriters of
Designated Securities shall act on behalf of each of such Underwriters, and the
parties hereto shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

          All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Company shall be delivered or sent by mail,
telex or facsimile transmission to the address of the Company set forth in the
Registration Statement: Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Company by the
Representatives upon request. Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

     13.  This Agreement and each Pricing Agreement shall be binding upon, and
inure solely to the benefit of, the Underwriters, the Company and, to the extent
provided in Sections 8 and 10 hereof, the officers and directors of the Company
and each person who controls the Company or any Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement or any such Pricing Agreement. No purchaser of any of the Securities
from any Underwriter shall be deemed a successor or assign by reason merely of
such purchase.

     14.  Time shall be of the essence of each Pricing Agreement. As used
herein, "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15.  THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

     16.  This Agreement and each Pricing Agreement may be executed by any one
or more of the parties hereto and thereto in any number of counterparts, each of
which shall be deemed to be an original, but all such respective counterparts
shall together constitute one and the same instrument.

c/o Goldman, Sachs & Co.
555 California Street, Suite 4500
San Francisco, CA  94104

Ladies and Gentlemen:

     Micron Technology, Inc., a Delaware corporation (the "Company"), proposes,
subject to the terms and conditions stated herein and in the Underwriting
Agreement, dated June 19, 1997, (the "Underwriting Agreement"), between the
Company on the one hand and Goldman, Sachs & Co., Montgomery Securities and
Robertson, Stephens & Company LLC on the other hand, to issue and sell to the
Underwriters named in Schedule I hereto (the "Underwriters") the Securities
specified in Schedule II hereto (the "Designated Securities" consisting of Firm
Securities and any Optional Securities the Underwriters may elect to purchase).
Each of the provisions of the Underwriting Agreement is incorporated herein by
reference in its entirety, and shall be deemed to be a part of this Agreement to
the same extent as if such provisions had been set forth in full herein; and
each of the representations and warranties set forth therein shall be deemed to
have been made at and as of the date of this Pricing Agreement, except that each
representation and warranty which refers to the Prospectus in Section 2 of the
Underwriting Agreement shall be deemed to be a representation or warranty as of
the date of the Underwriting Agreement in relation to the Prospectus (as therein
defined), and also a representation and warranty as of the date of this Pricing
Agreement in relation to the Prospectus as amended or supplemented relating to
the Designated Securities which are the subject of this Pricing Agreement. Each
reference to the Representatives herein and in the provisions of the
Underwriting Agreement so incorporated by reference shall be deemed to refer to
you. Unless otherwise defined herein, terms defined in the Underwriting
Agreement are used herein as therein defined. The Representatives designated to
act on behalf of the Representatives and on behalf of each of the Underwriters
of the Designated Securities pursuant to Section 12 of the Underwriting
Agreement and the address of the Representatives referred to in such Section 12
are set forth at the end of Schedule II hereto.

     An amendment to the Registration Statement, or a supplement to the
Prospectus, as the case may be, relating to the Designated Securities, in the
form heretofore delivered to you is now proposed to be filed with the
Commission.

     Subject to the terms and conditions set forth herein and in the
Underwriting Agreement incorporated herein by reference, (a) the Company agrees
to issue and sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Company at the time and
place and at the purchase price to the Underwriters set forth in Schedule II
hereto, the principal amount of Firm Securities set forth opposite the name of
such Underwriter in Schedule I hereto and, (b) in the event and to the extent
that the Underwriters shall exercise the election to purchase Optional
Securities, as provided below, the Company agrees to issue and sell to each of
the Underwriters, and each of the Underwriters agrees, severally and not
jointly, to purchase from the Company at the purchase price to the Underwriters
set forth in Schedule II hereto that portion of the principal amount of Optional
Securities as to which such election shall have been exercised.

     The Company hereby grants to each of the Underwriters the right to purchase
at their election up to the principal amount of Optional Securities set forth
opposite the name of such Underwriter in Schedule I hereto on 
<PAGE>
 
the terms referred to in the paragraph above for the sole purpose of covering
over-allotments in the sale of the Firm Securities. Any such election to
purchase Optional Securities may be exercised by written notice from the
Representatives to the Company given within a period of 30 calendar days after
the date of this Pricing Agreement, setting forth the principal amount of
Optional Securities to be purchased and the date on which such Optional
Securities are to be delivered, as determined by the Representatives, but in no
event earlier than the First Time of Delivery or, unless the Representatives and
the Company otherwise agree in writing, no earlier than two or later than ten
business days after the date of such notice.

     If the foregoing is in accordance with your understanding, please sign and
return to us seven (7) counterparts hereof, and upon acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof,
including the provisions of the Underwriting Agreement incorporated herein by
reference, shall constitute a binding agreement between each of the Underwriters
and the Company. It is understood that your acceptance of this letter on behalf
of each of the Underwriters is or will be pursuant to the authority set forth in
a form of Agreement among Underwriters, the form of which shall be submitted to
the Company for examination upon request, but without warranty on the part of
the Representatives as to the authority of the signers thereof.

                                    Very truly yours,

Ladies and Gentlemen:

     We understand that you propose to underwrite a public offering of ___%
Convertible Subordinated Notes due July 1, 2004 (the "Notes") of Micron

into common stock, $0.10 par value per share (the "Common Stock"), of Micron.
In consideration therefor and for other good and valuable consideration, and in
recognition of the benefits that will accrue to the undersigned as a result
thereof, the undersigned hereby irrevocably agrees that the undersigned will
not, from the date hereof and for a period of 30 days after the date of the
Pricing Agreement (the "Pricing Agreement") among the Company and the
Representatives in connection with such offering, without the prior written
consent of Goldman, Sachs & Co., (i) offer to sell, sell, contract to sell or
otherwise dispose of any of the Notes or any shares of Common Stock, any
securities substantially similar to the Notes or the Common Stock, including but
not limited to any securities that are convertible into or exchangeable for, or
that represent the right to receive Notes or shares of Common Stock or any
substantially similar securities (other than pursuant to employee stock option
or purchase plans existing on, or upon the conversion or exchange of convertible
or exchangeable securities outstanding as of, the date of the Pricing
Agreement), or (ii) establish a "put equivalent position" with respect to the
Notes or the Common Stock within the meaning of Rule 16a-1(h) under the
Securities Exchange Act of 1934, as amended, or (iii) publicly announce an
intention to take any of the actions set forth in (i) or (ii) above.

     The Company, the indenture trustee with respect to the Notes and the
transfer agent with respect to the Common Stock are hereby authorized to enforce
this agreement by refusing to permit transfers which the Company believes may
violate this agreement.

                                    Very truly yours,

covered by an opinion of, any specified Person, it is not necessary that all

Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and

 SECTION 104.   ACTS OF HOLDERS; RECORD DATES.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. The
Trustee shall promptly deliver to the Company copies of all such 

                                      -9-
<PAGE>
 
instrument or instruments delivered to the Trustee. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to Section 601) conclusive in favor of the Trustee and the Company,
if made in the manner provided in this Section.

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

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

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

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

                                     -10-
<PAGE>
 
     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
                                                        --------             
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities of the relevant
series on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company's expense, shall cause
notice of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106.

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

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

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

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

     (1) the Trustee by any Holder or by the Company shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing (or by
facsimile transmissions ((612) 667-9825), provided that oral confirmation of
receipt shall have been received) to or with the Trustee at its Corporate Trust
Office, Attention: Corporate Trust Department, or

                                     -11-
<PAGE>
 
     (2) the Company by the Trustee or by any Holder shall be sufficient for
every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class postage prepaid, to the Company addressed to it
at the address of its principal office specified in the first paragraph of this
instrument or at any other address previously furnished in writing to the
Trustee by the Company, Attention: Chief Financial Officer.

 SECTION 106.   NOTICE TO HOLDERS; WAIVER.

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

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

 SECTION 107.   CONFLICT WITH TRUST INDENTURE ACT.

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

 SECTION 108.   EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

 SECTION 109.   SUCCESSORS AND ASSIGNS.

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

 SECTION 110.   SEPARABILITY CLAUSE.

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

 SECTION 111.   BENEFITS OF INDENTURE.

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

 SECTION 112.   GOVERNING LAW.

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

 SECTION 113.   LEGAL HOLIDAYS.

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

 SECTION 114.   INDENTURE AND SECURITIES SOLELY CORPORATE OBLIGATIONS.

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

     [IF THE SECURITY IS CONVERTIBLE INTO COMMON STOCK OF THE COMPANY, INSERT --
Subject to the provisions of the Indenture, the Holder of this Security is
entitled, at its option, at any time on or before [insert date] (except that, in
case this Security or any portion hereof shall be called for redemption, such
right shall terminate with respect to this Security or portion hereof, as the
case may be, so called for redemption at the close of business on the first
Business Day next preceding the date fixed for redemption as provided in the
Indenture unless the Company defaults in making the payment due upon
redemption), to convert the principal amount of this Security (or any portion
hereof which is $1,000 or an integral multiple thereof), into fully paid and
non-assessable shares (calculated as to each conversion to the nearest 1/100th
of a share) of the Common Stock of the Company, as said shares shall be
constituted at the date of conversion, at the conversion price of $______
principal amount of Securities for each share of Common Stock, or at the
adjusted conversion price in effect at the date of conversion determined as
provided in the Indenture, upon surrender of this Security, together with the

or agency of the Company in ____________, accompanied (if so required by the
Company) by instruments of transfer, in form satisfactory to the Company and to
the Trustee, duly executed by the Holder or by its duly authorized attorney in
writing. Such surrender shall, if made during any period beginning at the close

payable on such Interest Payment Date on the principal amount of this Security
then being converted. Subject to the aforesaid requirement for payment and, in
the case of a conversion after the Regular Record Date next preceding any
Interest Payment Date and on or before such Interest Payment Date, to the right
of the Holder of this Security (or any Predecessor Security) of record at such
Regular Record Date to receive an installment of interest (with certain
exceptions provided in the Indenture), no adjustment is to be made on conversion
for interest accrued hereon or for dividends on shares of Common Stock issued on
conversion. The Company is not required to issue fractional shares upon any such
conversion, but shall make adjustment therefor in cash on the basis of the
current market value of such fractional interest as provided in the Indenture.
The conversion price is subject to adjustment as provided in the Indenture. In
addition, the Indenture provides that in case of certain consolidations or
mergers to which the Company is a party or the sale of substantially all of the
assets of the Company, the Indenture shall be amended, without the consent of
any Holders of Securities, so that this Security, if then outstanding, will be
convertible thereafter, during the period this Security shall be convertible as
specified above, only into the kind and amount of securities, cash and other
property receivable upon the consolidation, merger or sale by a holder of the
number of shares of Common Stock into which this Security might have been
converted immediately prior to such consolidation, merger or sale (assuming such
holder of Common Stock failed to exercise any rights of election and received
per share the kind and amount received per share by a plurality of non-electing
shares).  In the event of conversion of this Security in part only, a new

                                     -18-

Security or Securities for the unconverted portion hereof shall be issued in the
name of the Holder hereof upon the cancellation hereof.]

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

     The indebtedness evidenced by this Security is, to the extent and in the
manner provided in the Indenture, subordinate and subject in right of payment to
the prior payment in full of all Senior Debt of the Company, and this Security
is issued subject to such provisions of the Indenture with respect thereto. Each
Holder of this Security, by accepting the same, (a) agrees to and shall be bound
by such provisions, (b) authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
so provided and (c) appoints the Trustee his attorney-in-fact for any and all
such purposes.

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

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

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

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, 

                                     -19-
<PAGE>
 
the Holders of not less than 25% in principal amount of the Securities of this
series at the time Outstanding shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default as Trustee and offered
the Trustee reasonable indemnity, and the Trustee shall not have received from
the Holders of a majority in principal amount of Securities of this series at
the time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of and any premium and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or its attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $_____ and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

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

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

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

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

                                     -25-

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

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

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

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

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

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

     Each Security shall be dated the date of its authentication.

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

                                     -26-
<PAGE>
 
Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

 SECTION 304.   TEMPORARY SECURITIES.

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

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

 SECTION 305.   REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

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

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

                                     -27-
<PAGE>
 
     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

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

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

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

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

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

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

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

     (4) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a Global Security or any portion
thereof, whether pursuant to this Section, Section 304, 

                                     -28-
<PAGE>
 
306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form
of, and shall be, a Global Security, unless such Security is registered in the
name of a Person other than the Depositary for such Global Security or a nominee
thereof.

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

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

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

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

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

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

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

 SECTION 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to 

                                     -29-
<PAGE>
 
be payable to the Holder on the relevant Regular Record Date by virtue of having
been such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

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

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

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

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

                                     -30-
<PAGE>
 
which is converted, interest whose Stated Maturity is after the date of
conversion of such Security (or such part thereof) shall not be payable.

 SECTION 308.   PERSONS DEEMED OWNERS.

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

 SECTION 309.   CANCELLATION.

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

 SECTION 310.   COMPUTATION OF INTEREST.

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

                           SATISFACTION AND DISCHARGE

 SECTION 401.   SATISFACTION AND DISCHARGE OF INDENTURE.

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

                                     -31-
<PAGE>
 
     (1)  either

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

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

               (i)   have become due and payable, or

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

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

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

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

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

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

 SECTION 402.   APPLICATION OF TRUST MONEY.

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

                                     -32-
<PAGE>
 
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                 ARTICLE FIVE

                                   REMEDIES

 SECTION 501.   EVENTS OF DEFAULT.

     "Event of Default," wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
Fifteen or be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or

dealt with or which has expressly been included in this Indenture solely for the
benefit of series of Securities other than that series), and continuance of such
default or breach for a period of 60 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied and stating that such notice is a
"Notice of Default" hereunder; or

     (5) the entry by a court having jurisdiction in the premises of (A) a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or (B) a decree or order adjudging the

any such decree or order for relief or any such other decree or order unstayed
and in effect for a period of 90 consecutive days; or

                                     -33-
<PAGE>
 
     (6) the commencement by the Company of a voluntary case or proceeding under
any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or
insolvent, or the consent by it to the entry of a decree or order for relief in
respect of the Company in an involuntary case or proceeding under any applicable
Federal or State bankruptcy, insolvency, reorganization or other similar law or
to the commencement of any bankruptcy or insolvency case or proceeding against
it, or the filing by it of a petition or answer or consent seeking

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

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

 SECTION 502.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

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

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

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

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

                                     -34-
<PAGE>
 
          (B) the principal of (and premium, if any, on) any Securities of that
     series which have become due otherwise than by such declaration of
     acceleration and any interest thereon at the rate or rates prescribed
     therefor in such Securities,

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

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

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

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

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

     The Company covenants that if

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

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

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

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

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

     No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
                                                           --------  -------

trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

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

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

SECTION 506.   APPLICATION OF MONEY COLLECTED.

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

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

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

SECTION 507.   LIMITATION ON SUITS.

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

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

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

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

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

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

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

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

SECTION 509.   RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been 

                                     -37-
<PAGE>
 
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

SECTION 510.   RIGHTS AND REMEDIES CUMULATIVE.

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

SECTION 511.   DELAY OR OMISSION NOT WAIVER.

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

SECTION 512.   CONTROL BY HOLDERS.

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

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

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

SECTION 513.   WAIVER OF PAST DEFAULTS.

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

                                     -38-
<PAGE>
 
     (1) in the payment of the principal of or any premium or interest on any
Security of such series, or

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

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

SECTION 514.   UNDERTAKING FOR COSTS.

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

SECTION 515.   WAIVER OF USURY, STAY OR EXTENSION LAWS.

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

SECTION 601.   CERTAIN DUTIES AND RESPONSIBILITIES.

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

                                     -39-

SECTION 602.   NOTICE OF DEFAULTS.

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

SECTION 603.   CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 601:

     (1) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,

specifically prescribed) may, in the absence of bad faith on its part, rely upon
an Officers' Certificate;

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

     (5) the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

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

Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;
and

                                     -40-

attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

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

     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness. The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the Securities. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

SECTION 605.   MAY HOLD SECURITIES AND ACT AS TRUSTEE UNDER OTHER INDENTURES.

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

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

SECTION 606.   MONEY HELD IN TRUST.

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

SECTION 607.   COMPENSATION AND REIMBURSEMENT.

     The Company agrees

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

     (2) except as otherwise expressly provided herein, to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and

                                     -41-
<PAGE>
 
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

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

SECTION 608.   CONFLICTING INTERESTS.

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

SECTION 609.   CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

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

SECTION 610.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

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

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

                                     -42-
<PAGE>
 
     The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

     If at any time:

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

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

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

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

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

     The Company shall give notice of each resignation and each removal of the
Trustee with respect to the Securities of any series and each appointment of a
successor Trustee with respect to the Securities 

                                     -43-
<PAGE>
 
of any series to all Holders of Securities of such series in the manner provided
in Section 106. Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

SECTION 611.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

     In case of the appointment hereunder of a successor Trustee with respect to
the Securities of one or more (but not all) series, the Company, the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

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

                                     -44-

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

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

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

SECTION 613.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

SECTION 614.   APPOINTMENT OF AUTHENTICATING AGENT.

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

                                     -45-
<PAGE>
 
     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

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

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

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

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

segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due

Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

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

the Company is in default in the performance and observance of any of the terms,

necessary repairs, renewals, replacements, betterments and improvements thereof,
all as, and to the extent,  in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
                                       --------  -------

property of the Company, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company; provided, however, that the Company shall not be required to pay or
         --------  -------                                                  
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim (i) whose amount, applicability or validity is being contested in good
faith by appropriate proceedings or (ii) if the failure to pay or discharge

set forth in any covenant provided pursuant to Section 301(19), 901(2), 901(7),
1006 or 1007 for the benefit of the Holders of such series if before the time
for such compliance the Holders of at least 50% in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
term, provision or condition, but no such waiver shall extend to or affect such
term, provision or condition except to the extent so expressly waived, and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.

Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.

 SECTION 1103.   SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

     If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 45 days (or such
shorter period of time as may be acceptable to the Trustee) prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by lot, or in the Trustee's discretion, on
a pro rata basis, provided that the unredeemed portion of the principal amount
of any Security shall be in an authorized denomination (which shall not be less
than the minimum authorized denomination) for such Security. If less than all
the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

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

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

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

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

 SECTION 1104.   NOTICE OF REDEMPTION.

                                     -56-
<PAGE>
 
     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified in the Securities to be redeemed, to each
Holder of Securities to be redeemed, at its address appearing in the Security
Register.

     All notices of redemption shall state:

     (1)  the Redemption Date,

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

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

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

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

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

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

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

 SECTION 1105.   DEPOSIT OF REDEMPTION PRICE.

     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

     If any Security called for redemption is converted, any money deposited
with the Trustee or with a Paying Agent or so segregated and held in trust for
the redemption of such Security shall (subject to 

                                     -57-
<PAGE>
 
the right of any Holder of such Security to receive interest as provided in the
last paragraph of Section 307) be paid to the Company on Company Request, or if
then held by the Company, shall be discharged from such trust.

 SECTION 1106.   SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
                        --------  -------                                     
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

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

 SECTION 1107.   SECURITIES REDEEMED IN PART.

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

                                ARTICLE TWELVE

                                 SINKING FUNDS

 SECTION 1201.   APPLICABILITY OF ARTICLE.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment," and
any payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an "optional sinking fund 

                                     -58-
<PAGE>
 
payment." If provided for by the terms of any Securities, the cash amount of any
sinking fund payment may be subject to reduction as provided in Section 1202.
Each sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.

 SECTION 1202.   SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

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

 SECTION 1203.   REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                               ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

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

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

                                     -59-
<PAGE>
 
 SECTION 1302.   DEFEASANCE AND DISCHARGE.

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

 SECTION 1303.   COVENANT DEFEASANCE.

     Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1007, inclusive, and any covenants provided pursuant to Section 301(19), 901(2)
or 901(7) for the benefit of the Holders of such Securities and (2) the
occurrence of any event specified in Sections 501(4) (with respect to any of
Sections 1006 through 1007, inclusive, and any such covenants provided pursuant
to Section 301(19), 901(2) or 901(7)), shall be deemed not to be or result in an
Event of Default, and (3) the provisions of Article Fifteen shall cease to be
effective, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)) or Article Fifteen, whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or
Article or by reason of any reference in any such Section or Article to any
other provision herein or in any other document, but the remainder of this
Indenture and such Securities shall be unaffected thereby.

 SECTION 1304.   CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

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

                                     -60-
<PAGE>
 
     (1) The Company shall irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee which satisfies the requirements
contemplated by Section 609 and agrees to comply with the provisions of this
Article applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefits of the Holders of such Securities, (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment, money in an amount, or
(C) a combination thereof, in each case sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such
Securities on the respective Stated Maturities, in accordance with the terms of
this Indenture and such Securities. As used herein, "U.S. Government Obligation"
means (x) any security which is (i) a direct obligation of the United States of
America for the payment of which the full faith and credit of the United States
of America is pledged or (ii) an obligation of a Person controlled or supervised
by and acting as an agency or instrumentality of the United States of America
the payment of which is unconditionally guaranteed as a full faith and credit
obligation by the United States of America, which, in either case (i) or (ii),
is not callable or redeemable at the option of the issuer thereof, and (y) any
depositary receipt issued by a bank (as defined in Section 3(a)(2) of the
Securities Act) as custodian with respect to any U.S. Government Obligation
which is specified in Clause (x) above and held by such bank for the account of
the holder of such depositary receipt, or with respect to any specific payment
of principal of or interest on any U.S. Government Obligation which is so
specified and held, provided that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest
evidenced by such depositary receipt.

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

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

                                     -61-
<PAGE>
 
     (4) The Company shall have delivered to the Trustee an Officers'
Certificate to the effect that neither such Securities nor any other Securities
of the same series, if then listed on any securities exchange, will be delisted
as a result of such deposit.

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

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

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

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

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

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

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

     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 1306, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1304 in respect of any
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any such Paying Agent (including the Company acting as its
own 

                                     -62-
<PAGE>
 
Paying Agent) as the Trustee may determine, to the Holders of such Securities,
of all sums due and to become due thereon in respect of principal and any
premium and interest, but money so held in trust need not be segregated from
other funds except to the extent required by law. Money and U.S. Government
Obligations so held in trust shall not be subject to the provisions of Article
Fifteen.

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

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

 SECTION 1306.   REINSTATEMENT.

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

                               ARTICLE FOURTEEN

                            CONVERSION OF SECURITIES

 SECTION 1401.   APPLICABILITY OF ARTICLE.

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

 SECTION 1402.   EXERCISE OF CONVERSION PRIVILEGE.

                                     -63-
<PAGE>
 
     In order to exercise a conversion privilege, the Holder of a Security of a
series with such a privilege shall surrender such Security to the Company at the
office or agency maintained for that purpose pursuant to Section 1002,
accompanied by a duly executed conversion notice to the Company substantially in
the form set forth in Section 206 stating that the Holder elects to convert such
Security or a specified portion thereof. Such notice shall also state, if
different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock
which shall be issuable on such conversion shall be issued. Securities
surrendered for conversion shall (if so required by the Company or the Trustee)
be duly endorsed by or accompanied by instruments of transfer in forms
satisfactory to the Company and the Trustee duly executed by the registered
Holder or its attorney duly authorized in writing; and Securities so surrendered
for conversion (in whole or in part) during the period from the close of
business on any Regular Record Date to the opening of business on the next
succeeding Interest Payment Date (excluding Securities or portions thereof
called for redemption during the period beginning at the close of business on a
Regular Record Date and ending at the opening of business on the first Business
Day after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day) shall also be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such Interest Payment Date on the principal amount of
such Security then being converted, and such interest shall be payable to such
registered Holder notwithstanding the conversion of such Security, subject to
the provisions of Section 307 relating to the payment of Defaulted Interest by
the Company. As promptly as practicable after the receipt of such notice and of
any payment required pursuant to a Board Resolution and, subject to Section 303,
set forth, or determined in the manner provided, in an Officers' Certificate, or
established in one or more indentures supplemental hereto setting forth the
terms of such series of Security, and the surrender of such Security in
accordance with such reasonable regulations as the Company may prescribe, the
Company shall issue and shall deliver, at the office or agency at which such
Security is surrendered, to such Holder or on its written order, a certificate
or certificates for the number of full shares of Common Stock issuable upon the
conversion of such Security (or specified portion thereof), in accordance with
the provisions of such Board Resolution, Officers' Certificate or supplemental
indenture, and cash as provided therein in respect of any fractional share of
such Common Stock otherwise issuable upon such conversion. Such conversion shall
be deemed to have been effected immediately prior to the close of business on
the date on which such notice and such payment, if required, shall have been
received in proper order for conversion by the Company and such Security shall
have been surrendered as aforesaid (unless such Holder shall have so surrendered
such Security and shall have instructed the Company to effect the conversion on
a particular date following such surrender and such Holder shall be entitled to
convert such Security on such date, in which case such conversion shall be
deemed to be effected immediately prior to the close of business on such date)
and at such time the rights of the Holder of such Security as such Security
Holder shall cease and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock of the Company shall be
issuable upon such conversion shall be deemed to have become the Holder or
Holders of record of the shares represented thereby. Except as set forth above
and subject to the final paragraph of Section 307, no payment or adjustment
shall be made upon any conversion on account of any interest accrued on the
Securities (or any part thereof) surrendered for conversion or on account of any
dividends on the Common Stock of the Company issued upon such conversion.

                                     -64-
<PAGE>
 
     In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to or on the order of the Holder thereof, at the expense of the Company,
a new Security or Securities of the same series, of authorized denominations, in
aggregate principal amount equal to the unconverted portion of such Security.

 SECTION 1403.   NO FRACTIONAL SHARES.

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

York Stock Exchange, or if the Common Stock is not traded on the New York Stock
Exchange, on the principal exchange or market on which the Common Stock is
traded or quoted.

 SECTION 1404.   ADJUSTMENT OF CONVERSION PRICE.

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

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

 SECTION 1405.   NOTICE OF CERTAIN CORPORATE ACTIONS.

     In case:

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

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

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

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

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

 SECTION 1406.   RESERVATION OF SHARES OF COMMON STOCK.

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

Common Stock of the Company then issuable upon the conversion of all outstanding
Securities of any series that has conversion rights.

 SECTION 1407.   PAYMENT OF CERTAIN TAXES UPON CONVERSION.

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

 SECTION 1408.   NONASSESSABILITY.

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

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

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

                                     -67-
<PAGE>
 
which, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article or in accordance with the terms of the
supplemental indenture or Board Resolutions setting forth the terms of such
adjustments. The above provisions of this Section 1409 shall similarly apply to
successive consolidations, mergers, conveyances, sales, transfers or leases.
Notice of the execution of such a supplemental indenture shall be given by the
Company to the Holder of each Security of a series that is convertible into
Common Stock of the Company as provided in Section 106 promptly upon such
execution.

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


 SECTION 1410.   DUTIES OF TRUSTEE REGARDING CONVERSION.

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

 SECTION 1411.   REPAYMENT OF CERTAIN FUNDS UPON CONVERSION.

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

                                     -68-
<PAGE>
 
Article Fourteen shall after such conversion be repaid to the Company by the
Trustee upon the Company's written request.

                                ARTICLE FIFTEEN

                          SUBORDINATION OF SECURITIES

 SECTION 1501.   SECURITIES SUBORDINATE TO SENIOR DEBT.

     Except as otherwise provided in a supplemental indenture or pursuant to
Section 301, the Company covenants and agrees, and each Holder of a Security, by
its acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article, the indebtedness
represented by the Securities and the payment of the principal of and any
premium and interest on each and all of the Securities or on the account of the
purchase, redemption or other acquisition of the Securities or constituting a
sinking fund or defeasance payment by the Company to the Trustee or any Paying
Agent, as the case may be, in accordance with Article Twelve or Article
Thirteen, respectively, on the Securities are hereby expressly made subordinate
and subject in right of payment to the prior payment in full of all Senior Debt.
Notwithstanding the foregoing, this Article Fifteen shall not apply to the
application of any amounts deposited with the Trustee or any Paying Agent
pursuant to any sinking fund requirement or defeasance which, at the time such
amounts were deposited with the Trustee or Paying Agent, as the case may be,
such deposits were not prohibited by the provisions of this Article Fifteen
("Previous Payments").

     The expressions "prior payment in full," "payment in full" and "paid in
full" and any other similar term or phrase when used in this Article Fifteen
with respect to Senior Debt shall mean in the case of Senior Debt consisting of
contingent obligations in respect of letters of credit (or local guaranties, as
applicable), bankers' acceptances, interest rate protection agreements or
currency exchange or purchase agreements, the setting apart of cash or other
payment acceptable to holders of such Senior Debt sufficient to discharge such
portion of Senior Debt in an account for the exclusive benefit of the holders
thereof, in which account such holders shall be granted by the Company a first
priority perfected security interest, which first priority perfected security
interest shall have been retained by the holders of Senior Debt for a period of
time in excess of all applicable preference or other similar periods, if any,
under applicable bankruptcy, insolvency or creditors' rights laws.

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

     In the event of (a) any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization, debt restructuring or other similar
case or proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether or
not involving insolvency or bankruptcy, or (c) any assignment for the benefit of
creditors or any other marshaling of assets and liabilities of the Company, then
and in any such event the holders of Senior Debt shall be entitled to receive
payment in full of all amounts due or to become due on or in respect of all
Senior Debt in cash or other payment satisfactory to the holders of Senior Debt
before the Holders of the Securities 

                                     -69-
<PAGE>
 
are entitled to receive any payment on account of principal of or any premium or
interest on the Securities or on account of the purchase, redemption or other
acquisition of Securities or constituting a sinking fund or defeasance payment
by the Company to the Trustee or the Paying Agent, as the case may be, in
accordance with Article Twelve or Article Thirteen, respectively, on the
Securities (other than Previous Payments), and to that end the holders of Senior
Debt or their representative or representatives or the trustee or trustees under
any indenture under which any instruments evidencing any of such Senior Debt may
have been issued shall be entitled to receive, for application to the payment
thereof, any payment or distribution of any kind or character, whether in cash,
property or securities, which may be payable or deliverable in respect of the
Securities in any such case, proceeding, dissolution, liquidation or other
winding up or event, to the extent necessary to pay all Senior Debt in full in
cash or other payment satisfactory to the holders of Senior Debt, after giving
effect to any concurrent payment or distribution to or for the holders of other
Senior Debt.

     In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, before all Senior Debt is paid in full
in cash or other payment satisfactory to the holders of Senior Debt, then and in
such event such payment or distribution shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee, agent or other Person making payment or distribution of
assets of the Company for application to the payment of all Senior Debt
remaining unpaid, to the extent necessary to pay all Senior Debt in full, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Debt.

     For purposes of this Article only, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which are subordinated in right of
payment to all Senior Debt which may at the time be outstanding to substantially
the same extent as, or to a greater extent than, the Securities are so
subordinated as provided in this Article. The consolidation of the Company with,
or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the conveyance or transfer of its
properties and assets substantially as an entirety to another Person upon the
terms and conditions set forth in Article Eight shall not be deemed a
dissolution, winding up, liquidation, reorganization, assignment for the benefit
of creditors or marshaling of assets and liabilities of the Company for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or which acquires by conveyance or transfer such
properties and assets substantially as an entirety, as the case may be, shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions set forth in Article Eight.

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

     In the event that any Securities are declared due and payable before their
Stated Maturity, then and in such event the holders of the Senior Debt
outstanding at the time such Securities so become due and payable shall be
entitled to receive payment in full in cash or other payment satisfactory to the
holders of Senior Debt of all amounts due or to become due on or in respect of
all Senior Debt before the Holders 

                                     -70-
<PAGE>
 
of the Securities are entitled to receive any payment by the Company on account
of the principal of or any premium or interest on the Securities or on account
of the purchase, redemption or other acquisition of Securities or constituting a
any sinking fund or defeasance payment by the Company to the Trustee or the
Paying Agent, as the case may be, in accordance with Article Twelve or Article
Thirteen, respectively, on the Securities (other than Previous Payments);
provided, however, that nothing in this Section shall prevent the satisfaction
- --------  -------
of any sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202 Securities which have been acquired (upon
redemption or otherwise) prior to such declaration of acceleration or which have
been converted pursuant to Article Fourteen. If the payment of Securities is
accelerated because of an Event of Default, the Company and the Trustee shall
promptly notify holders of Senior Debt of the acceleration.

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

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

 SECTION 1504.   NO PAYMENT IN CERTAIN CIRCUMSTANCES.

     The Company may not make any payment of principal of, or premium, if any,
or interest on the Securities or on account of the purchase, redemption or other
acquisition of Securities or constituting any sinking fund or defeasance payment
by the Company to the Trustee or the Paying Agent, as the case may be, in
accordance with Article Twelve or Article Thirteen, respectively, on the
Securities (other than Previous Payments), if:

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

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

; provided, however, that nothing in this Section shall prevent the satisfaction
  --------  -------                                                             
of any sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202

                                     -71-
<PAGE>
 
Securities which have been acquired (upon redemption or otherwise) prior to such
declaration of acceleration or which have been converted pursuant to Article
Fourteen.

     If the Trustee receives any Payment Blockage Notice pursuant to clause (ii)
above, no subsequent Payment Blockage Notice shall be effective for purposes of
this Section unless and until at least 365 days shall have elapsed since the
initial effectiveness of the immediately prior Payment Blockage Notice.  No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

     The Company may and shall resume payments on and distributions in respect
of the Securities and may purchase, redeem or otherwise acquire Securities and
may make a sinking fund or defeasance payment to the Trustee or the Paying
Agent, as the case may be, in accordance with Article Twelve or Article
Thirteen, respectively, on the Securities, upon the earlier of:

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

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

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

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

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

 SECTION 1505.   PAYMENT PERMITTED IF NO DEFAULT.

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

                                     -72-
<PAGE>
 
 SECTION 1506.   SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

     Subject to the payment in full of all Senior Debt, the Holders of the
Securities shall be subrogated to the rights of the holders of such Senior Debt
to receive payments and distributions of cash, property and securities
applicable to the Senior Debt until the principal of and any premium and
interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Debt by Holders of the Securities or the Trustee, shall, as among the
Company, its creditors other than holders of Senior Debt and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Debt.

 SECTION 1507.   PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

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

 SECTION 1508.   TRUSTEE TO EFFECTUATE SUBORDINATION.

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

 SECTION 1509.   NO WAIVER OF SUBORDINATION PROVISIONS.

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

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders 

                                     -73-
<PAGE>
 
of the Securities, without incurring responsibility to the Holders of the
Securities and without impairing or releasing the subordination provided in this
Article or the obligations hereunder of the Holders of the Securities to the
holders of Senior Debt, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt
or any instrument evidencing the same or any agreement under which Senior Debt
is outstanding; (ii) sell, exchange, release or otherwise dispose of any
property pledged, mortgaged or otherwise securing Senior Debt; (iii) release any
Person liable in any manner for the collection of Senior Debt; and (iv) exercise
or refrain from exercising any rights against the Company and any other Person.

 SECTION 1510.   NOTICE TO TRUSTEE.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Debt or from any trustee or other Representative
therefor; and, prior to the receipt of any such written notice, the Trustee,
subject to the provisions of Section 601, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Trustee shall
                                 --------  -------                           
not have received the notice provided for in this Section by at least 12:00 noon
New York City time one Business Day prior to the date upon which by the terms
hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of and any premium or interest on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such money and to apply
the same to the purpose for which such money was received and shall not be
affected by any notice to the contrary which may be received by it after 12:00
noon New York City time one Business Day prior to such date.

     Subject to the provisions of Section 601, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Debt (or a trustee or other Representative therefor) to
establish that such notice has been given by a holder of Senior Debt (or a
trustee or other Representative therefor). In the event that the Trustee
determines in good faith that further evidence is required with respect to the
right of any Person as a holder of Senior Debt to participate in any payment or

     Upon any payment or distribution of assets of the Company referred to in

Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit

ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.

 SECTION 1512.   TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

     The Trustee, in its capacity as trustee under this Indenture, shall not be
deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be

cash, property or securities to which any holders of Senior Debt shall be
entitled by virtue of this Article or otherwise.

 SECTION 1513.   RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION OF
TRUSTEE'S RIGHTS.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article with respect to any Senior Debt which may at any time

holder.

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

 SECTION 1514.   ARTICLE APPLICABLE TO PAYING AGENTS.

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

 SECTION 1515.   CERTAIN CONVERSIONS DEEMED PAYMENT.

     For the purposes of this Article only, (1) the issuance and delivery of
junior securities upon conversion of Securities in accordance with Article
Fourteen shall not be deemed to constitute a payment or distribution on account
of the principal of or any premium or interest on Securities or on account of

                                     -75-
<PAGE>
 
the purchase, redemption or other acquisition of Securities, and (2) the
payment, issuance or delivery of cash, property or securities (other than junior
securities and cash paid for fractional shares) upon conversion of a Security
shall be deemed to constitute payment on account of the principal of such
Security. For the purposes of this Section, the term "junior securities" means
(a) shares of any stock of any class of the Company and (b) securities of the
Company which are subordinated in right of payment to all Senior Debt which may
be outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Securities
are so subordinated as provided in this Article.

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

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

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

 SECTION 1517.   RELIANCE BY HOLDERS OF SENIOR INDEBTEDNESS ON SUBORDINATION
PROVISIONS.

     Each Holder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Senior Debt, whether such Senior Debt
was created or acquired before or after the issuance of the Securities, to
acquire and continue to hold, or to continue to hold, such Senior Debt and such
holder of Senior Debt shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Debt, and no amendment or modification of the provisions
contained herein shall diminish the rights of such holders of Senior Debt unless
such holders shall have agreed in writing hereto.

No. _________                                          $_____________

     Micron Technology, 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 hereinafter referred to), for value
received, hereby promises to pay to ________________, or registered assigns, the
principal sum of ___________________ Dollars on July 1, 2004 and to pay interest
thereon from June 24, 1997 or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, semi-annually on January 1
and July 1 in each year, commencing January 1, 1998, at the rate of 7% 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 Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest, which shall be
the December 15 or June 15 (whether or not a Business Day), as the case may be,
next preceding such Interest Payment Date, subject to the right of the Company
to defer interest during an Extension Period. Any such interest not so
punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name this Security (or one or more Predecessor Securities) 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
Securities of this series 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 Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in said Indenture.

     So long as no Event of Default under the Indenture has occurred and is
continuing, the Company shall have the right at any time during the term of the
Securities to defer interest payments from time to time by extending the
interest payment period for successive periods (each, an "Extension Period") not
exceeding 4 consecutive semi-annual interest payment periods for each such
period; provided, that no Extension Period may extend beyond the Stated Maturity
        --------                                                                
of the Securities. At the end of each Extension Period, the Company shall be
responsible for the payment of, and the Company shall pay to the Person in whose
name this Security is registered at the close of business on the Regular Record
Date next preceding such payment date all interest then accrued and unpaid
together with interest thereon compounded semi-annually at the rate specified
for the Securities to the extent permitted by applicable law; provided, that
                                                              --------      
during any Extension Period, the Company shall not, and shall not allow any of
its Subsidiaries to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Company's capital stock or (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees of indebtedness for money borrowed) of the Company that
rank pari passu with or junior to the Notes (other than (a) any 

                                       2
<PAGE>
 
dividend, redemption, liquidation, interest, principal or guarantee payment by
the Company where the payment is made by way of securities (including capital
stock) that rank pari passu with or junior to the securities on which such
dividend, redemption, interest, principal or guarantee payment is being made,
(b) purchases of the Company's Common Stock related to the issuance of the
Company's Common Stock under any of the Company's benefit plans for its
directors, officers or employees, (c) as a result of a reclassification of the
Company's capital stock or the exchange or conversion of one series or class of
the Company's capital stock for another series or class of the Company's capital
stock, and (d) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged). Prior to the termination of
any such Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period together with all previous and further
- --------                                                           
extensions thereof may not exceed 4 consecutive semi-annual interest payment
periods and may not extend beyond the Stated Maturity of the Securities. Upon
the termination of any Extension Period and the payment of all amounts then due,
the Company may commence a new Extension Period, subject to the above
requirements. No interest during an Extension Period shall be due and payable
except at the end thereof.

     The Company shall give written notice to the Trustee of its election to
begin an Extension Period at least one Business Day prior to the earlier of (i)
the Regular Record Date for the Interest Payment Date on the Securities that
would have been payable but for the election to begin such Extension Period or
(ii) if the Securities are listed on the New York Stock Exchange, Inc. ("NYSE")
or other stock exchange or quotation system, the date the Company is required to
give notice to the NYSE or other applicable self-regulatory organization or to
Holders of the Securities of the Regular Record Date or the date such interest
is payable.

     Payment of the principal of (and premium, if any) and any interest on this
Security will be made at Corporate Trust Office of the Trustee 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; provided, however, that at the
                                                --------  -------             
option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, 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 the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

Common Stock is at least 130% of the Conversion Price for at least 20 Trading
Days within a period of 30 consecutive Trading Days ending within five Trading
Days of the call for redemption.

     The Redemption Price (expressed as a percentage of principal amount) is as

and thereafter is equal to 100% of the principal amount, in each case together
with accrued and unpaid interest (including any unpaid interest, compounded
semi-annually, that has accrued during any Extension Period) to, but excluding,
the Redemption Date; provided, however, that interest installments whose Stated
                     --------  -------                                         
Maturity is on or prior to such Redemption Date will be payable to the Holders
of such Securities, or one or more Predecessor Securities, of record at the
close of business on the relevant Record Dates referred to on the face hereof,
all as provided in the Indenture.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder hereof upon the cancellation hereof.

     If a Change in Control occurs, the Holder of this Security, at the Holder's
option, shall have the right, in accordance with the provisions of the
Indenture, to require the Company to repurchase this Security (or any portion of
the principal amount hereof that is $1,000 or any integral multiple of $1,000 in
excess thereof, provided that the portion of the principal amount of this
                --------                                                 
Security to be Outstanding after such repurchase is at least equal to $1,000)
for cash at a Repurchase Price equal to 100% of the principal amount thereof
plus interest accrued to, but excluding, the Repurchase Date (including any
unpaid interest, compounded semi-annually, that has accrued during any Extension
Period).  At the option of the Company, the Repurchase Price may be paid in cash
or, subject to the conditions provided in the Indenture, by delivery of shares
of Common Stock having a fair market value equal to the Repurchase Price.  For
purposes of this paragraph, the fair market value of shares of Common Stock
shall be determined by the Company and shall be equal to 95% of the average of
the Closing Prices Per Share for the five consecutive Trading Days immediately
preceding the second Trading Day prior to the Repurchase Date.  Whenever in this
Security there is a reference, in any context, to the principal of any Security
as of any time, such reference shall be deemed to include reference to the
Repurchase Price payable in respect of such Security to the extent that such
Repurchase Price is, was or would be so payable at such time, and express
mention of the Repurchase Price in any provision of this Security shall not be
construed as excluding the Repurchase Price so payable in those provisions of
this Security when such express mention is not made; provided, however, that,
                                                     --------  -------       
for the purposes of the succeeding paragraph, such reference shall be 

                                       5
<PAGE>
 
deemed to include reference to the Repurchase Price only to the extent the
Repurchase Price is payable in cash.

     The indebtedness evidenced by this Security is, to the extent and in the
manner provided in the Indenture, subordinate and subject in right of payment to
the prior payment in full of all Senior Debt of the Company, and this Security
is issued subject to such provisions of the Indenture with respect thereto.
Each Holder of this Security, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on his or her
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee as his or her attorney-
in-fact for any and all such purposes.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

     Subject to the provisions of the Indenture, the Holder of this Security is
entitled, at its option, at any time on or before July 1, 2004 (except that, in
case this Security or any portion hereof shall be called for redemption or
submitted for repurchase, such right shall terminate with respect to this
Security or portion hereof, as the case may be, so called for redemption or
submitted for repurchase, as the case may be, at the close of business on the
first Business Day next preceding the date fixed for redemption or repurchase,
as the case may be, as provided in the Indenture unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be), to
convert the principal amount of this Security (or any portion hereof which is
$1,000 or an integral multiple thereof) into fully paid and non-assessable
shares of the Common Stock of the Company, as said shares shall be constituted
at the date of conversion, at the Conversion Rate of 14.8272 shares of Common
Stock for each $1,000 principal amount of Securities, or at the adjusted
Conversion Rate in effect at the date of conversion determined as provided in
the Indenture, upon surrender of this Security, together with the conversion
notice hereon duly executed, to the Corporate Trust Office of the Trustee
accompanied (if so required by the Company) by instruments of transfer, in form
satisfactory to the Company and to the Trustee, duly executed by the Holder or
by its duly authorized attorney in writing. Such surrender (other than during an
Extension Period) shall, if made during any period beginning at the close of
business on a Regular Record Date and ending at the opening of business on the
Interest Payment Date next following such Regular Record Date (unless this
Security or the portion being converted shall have been called for redemption on
a Redemption Date during the period beginning at the close of business on a
Regular Record Date and ending at the opening of business on the first Business
Day after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day), also be accompanied
by payment in funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of this Security
then being converted. Subject to the aforesaid requirement for payment and, in
the case of a conversion after the Regular Record Date next preceding any
Interest Payment Date and on or before such Interest Payment Date, to the right
of the Holder of this Security (or any Predecessor Security) of record at such
Regular Record Date to receive an installment of interest (with certain
exceptions provided in the Indenture), no adjustment is to be made on conversion
for interest accrued hereon or for dividends on shares of Common Stock

                                       6

issued on conversion. If, during any Extension Period, this Security (or portion
hereof) called for redemption is surrendered for conversion, any accrued and
unpaid interest on this Security (or portion hereof) as of the Interest Payment
Date occurring on or immediately preceding the conversion date for this Security
shall be paid in cash to the Holder surrendering such Security for conversion.
The Company is not required to issue fractional shares upon any such conversion,
but shall make adjustment therefor as provided in the Indenture. The Conversion
Rate is subject to adjustment as provided in the Indenture. In addition, the
Indenture provides that in case of certain consolidations or mergers to which
the Company is a party or the sale of substantially all of the assets of the
Company, the Indenture shall be amended, without the consent of any Holders of
Securities, so that this Security, if then outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon the consolidation, merger or sale by a holder of the number of
shares of Common Stock into which this Security might have been converted
immediately prior to such consolidation, merger or sale (assuming such holder of
Common Stock failed to exercise any rights of election and received per share
the kind and amount received per share by a plurality of non-electing shares).
In the event of conversion of this Security in part only, a new Security or
Securities for the unconverted portion hereof shall be issued in the name of the
Holder hereof upon the cancellation hereof.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

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

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

                                       7
<PAGE>
 
time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in principal amount of Securities of this series at the
time Outstanding a direction inconsistent with such request, and shall have
failed to institute any such proceeding, for 60 days after receipt of such
notice, request and offer of indemnity. The foregoing shall not apply to any
suit instituted by the Holder of this Security for the enforcement of any
payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of and any premium and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or its attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

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

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

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

                               ISSUANCE OF NOTES.

 Section 101 Issuance of Notes; Principal Amount; Maturity.

     (a) On June 24, 1997, the Company shall issue and deliver to the Trustee,
and the Trustee shall authenticate, Notes substantially in the form set forth
above, in each case with such appropriate insertions, omissions, substitutions
and other variations as are required or permitted by the Indenture and this
Supplemental Indenture, and with such letters, numbers, or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any Notes exchange or as may, consistently
herewith, be determined by the officers executing such Notes, as evidenced by
their execution of such Notes.

     (b) The Notes shall be issued in the aggregate principal amount of
$435,000,000 (or $500,000,000 if the over-allotment option set forth in Section
3 of the Underwriting Agreement dated June 19, 1997 (as amended from time to
time by the parties thereto) by and between the Company and the Underwriters is
exercised in full) and shall mature on July 1, 2004.

 Section 102 Interest on the Notes; Payment of Interest.

     (a) The Notes shall bear interest at the rate of 7% per annum from June 24,
1997.

     (b) The interest so payable, and punctually paid or duty provided for, on
any Interest Payment Date shall, as provided in such Indenture, be paid to the
Person in whose name a Note is registered at the close of business on the
Regular Record Date for such interest, which shall be the December 15 or June 15
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date, subject to the right of the Company to defer interest
during an Extension Period pursuant to 102(c).  Any such interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date and may either be paid to the Person in whose
name the Note 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 Notes of this series not less than 10
calendar 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 Notes exchange
on which the Notes of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture.

     (c) So long as no Event of Default under the Indenture has occurred and is
continuing, the Company shall have the right at any time during the term of the
Notes to defer interest payments from time to time by extending the interest
payment period for successive periods (each, an "Extension Period") not

accrued and unpaid together with interest thereon compounded semi-annually at
the rate specified for the Notes to the extent permitted by applicable law;

allow any of its Subsidiaries to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees of indebtedness for money borrowed) of the
Company that rank pari passu with or junior to the Notes (other than (a) any
dividend, redemption, liquidation, interest, principal or guarantee payment by

the Company's capital stock for another series or class of the Company's capital
stock, and (d) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged). Prior to the termination of
any such Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period together with all previous and further
extensions thereof may not exceed 4 consecutive semi-annual interest payment
periods and may not extend beyond the Stated Maturity of the Notes. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Company may commence a new Extension Period, subject to the above requirements.
No interest during an Extension Period shall be due and payable except at the
end thereof.

     The Company shall give written notice to the Trustee of its election to
begin such Extension Period at least one Business Day prior to the earlier of

payable.

the Notes shall be made at the Corporate Trust Office of the Trustee 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; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address appears in the Note
Register.

                              CONVERSION OF NOTES

 Section 501 Conversion Privilege and Conversion Rate.

     Subject to and upon compliance with the provisions of this Article, at the
option of the Holder thereof, any Note may be converted into fully paid and
nonassessable shares (calculated as to each conversion to the nearest 1/100 of a
share) of Common Stock of the Company at the Conversion Rate, determined as
hereinafter provided, in effect at the time of conversion.  Such conversion
right shalt commence immediately and expire at the close of business on July 1,
2004, subject, in the case of the conversion of any Global Note, to any
applicable book-entry procedures of the Depositary therefor.  In case a Note is
called for redemption at the election of the Company or the Holder thereof
exercises his right to require the Company to repurchase the Note, such
conversion right in respect of the Note shall expire at the close of business on
the Business Day next preceding the Redemption Date or the Repurchase Date (as
defined in Article Six), as the case may be, unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be (in
each case subject as aforesaid to any applicable book entry procedures).

     If, during any Extension Period, a Note (or portion thereof) called for
redemption is surrendered for conversion, any accrued and unpaid interest on
such Note (or portion thereof) as of the Interest Payment Date occurring on or
immediately preceding the conversion date for such Note (or portion thereof)
shall be paid in cash to the Holder surrendering such Note for conversion.

     The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the "Conversion Rate") shall be initially 14.8272 shares of
Common Stock for each $1,000 principal amount of Notes.  The Conversion Rate
shall be adjusted in certain instances as provided in this Article 502.

Section 502  Adjustment of Conversion Rate.

     The Conversion Rate shalt be subject to adjustment from time to time as
follows:

     (1) In case the Company shall pay or make a dividend or other distribution
on Common Stock payable in shares of Common Stock, the Conversion Rate in effect
at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such

                                      16
<PAGE>
 
dividend or other distribution shall be increased by dividing such Conversion
Rate by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such number of shares and
the total number of shares constituting such dividend or other distribution,
such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If, after any such date
fixed for determination, any dividend or distribution is not in fact paid, the
Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would have been in effect if such determination date had
not been fixed. For the purposes of this paragraph (1), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

     (2) In case the Company shall issue rights, options or warrants to all
holders of its Common Stock entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the current market price per
share (determined as provided in paragraph (8) of this Section 502) of the
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than any rights, options or
warrants that by their terms will also be issued to any Holder upon conversion
of a Note into shares of Common Stock without any action required by the Company
or any other Person), the Conversion Rate in effect at the opening of business
on the day following the date fixed for such determination shall be increased by
dividing such Conversion Rate by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
current market price and the denominator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination.  If, after any such date fixed for determination, any such
rights, options or warrants are not in fact issued, or are not exercised prior
to the expiration thereof, the Conversion Rate shall be immediately readjusted,
effective as of the date such rights, options or warrants expire, or the date
the Board of Directors determines not to issue such rights, options or warrants,
to the Conversion Rate that would have been in effect if the unexercised rights,
options or warrants had never been granted or such determination date had not
been fixed, as the case may be.  For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common
Stock.  The Company will not issue any rights, options or warrants in respect of
shares of Common Stock held in the treasury of the Company.

     (3) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the 

                                      17
<PAGE>
 
day following the day upon which such subdivision becomes effective shall be
proportionately increased, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock,
the Conversion Rate in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
reduced, such increase or reduction, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.

     (4) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock evidences of its indebtedness, shares of any class
of capital stock, or other property (including Notes, but excluding (i) any
rights, options or warrants referred to in paragraph (2) of this Section, (ii)
any dividend or distribution paid exclusively in cash, (iii) any dividend or
distribution referred to in paragraph (1) of this Section) the Conversion Rate
shall be adjusted so that the same shall equal the rate determined by dividing
the Conversion Rate in effect immediately prior to the close of business on the
date fixed for the determination of stockholders entitled to receive such
distribution by a fraction of which the numerator shall be the current market
price per share (determined as provided in paragraph (8) of this Section 502) of
the Common Stock on the date fixed for such determination less the then fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution filed with the Trustee) of the
portion of the assets, shares or evidences of indebtedness so distributed
applicable to one share of Common Stock and the denominator shall be such
current market price per share of the Common Stock, such adjustment to become
effective immediately prior to the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
distribution. If, after any such date fixed for determination, any such
distribution is not in fact made, the Conversion Rate shall be immediately
readjusted, effective as of the date the Board of Directors determines not to
make such distribution, to the Conversion Rate that would have been in effect if
such determination date had not been fixed.

     (5) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any cash that is distributed as part
of a distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with (I) the aggregate amount of any other cash
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no adjustment pursuant to this paragraph (5) has been made and (II) the
aggregate of any cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) of consideration payable in respect of any tender offer by the
Company or any of its subsidiaries for all or any portion of the Common Stock
concluded within the 12 months preceding the date of payment of such
distribution and in respect of which no adjustment pursuant to paragraph (6) of
this Section 502 has been made (the "combined cash and tender amount") exceeds
12.5% of the product of the current market price per share (determined as
provided in paragraph (8) of this Section 502) of the Common Stock on the date
for the determination of holders of shares of Common Stock entitled to receive
such distribution times the number of shares of Common Stock outstanding on such
date (the "aggregate current market price"), then, and in each such case,
immediately after the close of business on such date for determination, 

                                      18
<PAGE>
 
the Conversion Rate shall be adjusted so that the same shall equal the rate
determined by dividing the Conversion Rate in effect immediately prior to the
close of business on the date fixed for determination of the stockholders
entitled to receive such distribution by a fraction (i) the numerator of which
shall be equal to the current market price per share (determined as provided in
paragraph (8) of this Section 502) of the Common Stock on the date fixed for
such determination less an amount equal to the quotient of (x) the excess of
such combined cash and tender amount over such aggregate current market price
divided by (y) the number of shares of Common Stock outstanding on such date for
determination and (ii) the denominator of which shall be equal to the current
market price per share (determined as provided in paragraph (8) of this Section
502) of the Common Stock on such date for determination.

     (6) In case a tender offer made by the Company or any Subsidiary for all or
any portion of the Common Stock shall expire and such tender offer (as amended
upon the expiration thereof) shall require the payment to stockholders (based on
the acceptance (up to any maximum specified in the terms of the tender offer) of
Purchased Shares (as defined below)) of an aggregate consideration having a fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution) that combined together with
(I) the aggregate of the cash plus the fair market value (as determined by the
Board of Directors, whose determination shall be conclusive and described in a
Board Resolution), as of the expiration of such tender offer, of consideration
payable in respect of any other tender offer by the Company or any Subsidiary
for all or any portion of the Common Stock expiring within the 12 months
preceding the expiration of such tender offer and in respect of which no
adjustment pursuant to this paragraph (6) has been made and (II) the aggregate
amount of any cash distributions to all holders of the Company's Common Stock
within 12 months preceding the expiration of such tender offer and in respect of
which no adjustment pursuant to paragraph (5) of this Section has been made (the
"combined tender and cash amount") exceeds 12.5% of the product of the current
market price per share of the Common Stock (determined as provided in paragraph
(8) of this Section 502) as of the last time (the "Expiration Time") tenders
could have been made pursuant to such tender offer (as it may be amended) times
the number of shares of Common Stock outstanding (including any tendered shares)
as of the Expiration Time, then, and in each such case, immediately prior to the
opening of business on the day after the date of the Expiration Time, the
Conversion Rate shall be adjusted so that the same shall equal the rate
determined by dividing the Conversion Rate immediately prior to close of
business on the date of the Expiration Time by a fraction (i) the numerator of
which shall be equal to (A) the product of (I) the current market price per
share of the Common Stock (determined as provided in paragraph (8) of this
Section 502) on the date of the Expiration Time multiplied by (II) the number of
shares of Common Stock outstanding (including any tendered shares) on the
Expiration Time less (B) the combined tender and cash amount, and (ii) the
denominator of which shall be equal to the product of (A) the current market
price per share of the Common Stock (determined as provided in paragraph (8) of
this Section 502) as of the Expiration Time multiplied by (B) the number of
shares of Common Stock outstanding (including any tendered shares) as of the
Expiration Time less the number of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted up to any such maximum,
being referred to as the "Purchased Shares").

                                      19
<PAGE>
 
     (7) The reclassification of Common Stock into Notes including other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 1409 of the Indenture applies) shall be deemed to involve (a) a
distribution of such Notes other than Common Stock to all holders of Common
Stock (and the effective date of such reclassification shall be deemed to be
"the date fixed for the determination of stockholders entitled to receive such
distribution" and "the date fixed for such determination" within the meaning of
paragraph (4) of this Section), and (b) a subdivision or combination, as the
case may be, of the number of shares of Common Stock outstanding immediately
prior to such reclassification into the number of shares of Common Stock
outstanding immediately thereafter (and the effective date of such
reclassification shall be deemed to be "the day upon which such subdivision
becomes effective" or "the day upon which such combination becomes effective",
as the case may be, and "the day upon which such subdivision or combination
becomes effective" within the meaning of paragraph (3) of this Section 502).

     (8) For the purpose of any computation under paragraphs (2), (4), (5) or
(6) of this Section 502, the current market price per share of Common Stock on
any date shall be calculated by the Company and be deemed to be the average of
the daily Closing Prices Per Share for the five consecutive Trading Days
selected by the Company commencing not more than 10 Trading Days before, and
ending not later than, the earlier of the day in question and the day before the
"ex" date with respect to the issuance or distribution requiring such
computation.  For purposes of this paragraph, the term "'ex' date", when used
with respect to any issuance or distribution, means the first date on which the
Common Stock trades regular way in the applicable securities market or on the
applicable securities exchange without the right to receive such issuance or
distribution.

     (9) No adjustment in the Conversion Rate shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(9)) would require an increase or decrease of at least one percent in such rate;
provided, however, that any adjustments which by reason of this paragraph (9)
- --------  -------                                                            
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment.  All calculations under this Article shall be made to
the nearest cent or to the nearest one-hundredth of a share, as the case may be.

     (10) The Company may make such increases in the Conversion Rate, for the
remaining term of the Notes or any shorter term, in addition to those required
by paragraphs (1), (2), (3), (4), (5) and (6) of this Section 502, as it
considers to be advisable in order to avoid or diminish any income tax to any
holders of shares of Common Stock resulting from any dividend or distribution of
stock or issuance of rights or warrants to purchase or subscribe for stock or
from any event treated as such for income tax purposes.  The Company shall have
the power to resolve any ambiguity or correct any error in this paragraph (10)
and its actions in so doing shall, absent manifest error, be final and
conclusive.

     (11) Notwithstanding the foregoing provisions of this Section, no
adjustment of the Conversion Rate shall be required to be made (a) upon the
issuance of shares of Common Stock pursuant to any present or future plan for
the reinvestment of dividends or (b) because of a tender or 

                                      20
<PAGE>
 
exchange offer of the character described in Rule 13e-4(h)(5) under the Exchange
Act or any successor rule thereto.

     (12) To the extent permitted by applicable law, the Company from time to
time may increase the Conversion Rate by any amount for any period of time if
the period is at least twenty (20) days, the reduction is irrevocable during
such period, and the Board of Directors shall have made a determination that
such reduction would be in the best interests of the Company, which
determination shall be conclusive; provided, however, that no such reduction
                                   --------  -------
shall be taken into account for purposes of determining whether the Closing
Price Per Share of the Common Stock exceeds the Conversion Price by 105% in
connection with an event which would otherwise be a Change of Control pursuant
to Section 604(4). Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall give notice of the reduction to the
Holders in the manner provided in Section 106 of the Indenture at least fifteen
(15) days prior to the date the increased Conversion Rate takes effect, and such
notice shall state the increased Conversion Rate and the period during which it
will be in effect.


             ARTICLE SIX REPURCHASE OF NOTES AT THE OPTION OF THE
                       HOLDER UPON A CHANGE OF CONTROL.

 Section 601 Right to Require Repurchase.

     In the event that a Change in Control (as hereinafter defined) shall occur,
then each Holder shall have the right, at the Holder's option, but subject to
the provisions of Section 602, to require the Company to repurchase, and upon
the exercise of such right the Company shall repurchase, all of such Holder's
Notes not theretofore called for redemption, or any portion of the principal
amount thereof that is equal to $1,000 or any integral multiple of $1,000 in
excess thereof (provided that no single Note may be repurchased in part unless
                --------                                                      
the portion of the principal amount of such Note to be Outstanding after such
repurchase is equal to $1,000 or integral multiples of $1,000 in excess
thereof), on the date (the "Repurchase Date") that is 45 days after the date of
the Company Notice (as defined in Section 603) at a purchase price equal to 100%
of the principal amount of the Notes to be repurchased plus interest accrued to,
but excluding, the Repurchase Date (including any unpaid interest that has
accrued during the Extension Period) (the "Repurchase Price"); provided,
                                                               -------- 
however, that installments of interest on Notes whose Stated Maturity is on or
- -------                                                                       
prior to the Repurchase Date shall be payable to the Holders of such Notes, or
one or more Predecessor Notes, registered as such on the relevant Record Date
according to their terms and the provisions of Section 307 of the Indenture.
Such right to require the repurchase of the 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 Indenture, unless a Change in Control shall
have occurred prior to such discharge.  At the option of the Company, the
Repurchase Price may be paid in cash or, subject to the fulfillment by the
Company of the conditions set forth Section 602, by delivery of shares of Common
Stock having a fair market value equal to the Repurchase Price.  Whenever in
this Supplemental Indenture or the Indenture (including in the Form of Note,
Section 101 of this Supplemental Indenture, and Sections 501(1) and 508 of the
Indenture) there is a reference, in any context, to the principal of any

Repurchase Price payable in respect of such Note to the extent that such
Repurchase Price is, was or would be so payable at such time, and express
mention of the Repurchase Price in any provision of this Supplemental Indenture
shall not be construed as excluding the Repurchase Price in those provisions of
this Supplemental Indenture or Indenture when such express mention is not made;
provided, however, that for the purposes of Article Fifteen of the Indenture
- --------  -------

to the extent the Repurchase Price is payable in cash.

Section 602 Conditions to the Company's Election to Pay the Repurchase Price in
Common Stock.

     The Company may elect to pay the Repurchase Price by delivery of shares of
Common Stock pursuant to Section 601 if and only if the following conditions
shall have been satisfied:

     (1) The shares of Common Stock deliverable in payment of the Repurchase

     (2) The Repurchase Price shall be paid only in cash in the event any shares

Securities Act upon repurchase and if such registration is not completed or does
not become effective prior to the Repurchase Date, and/or (ii) require
registration with or approval of any governmental authority under any state law
or any other federal law before such shares may be validly issued or delivered
upon repurchase and if such registration is not completed or does not become
effective or such approval is not obtained prior to the Repurchase Date;

     (3) Payment of the Repurchase Price may not be made in Common Stock unless
such stock is, or shall have been, approved for listing on the New York Stock
Exchange or quotation on the Nasdaq National Market, in either case, prior to
the Repurchase Date; and

     (4) All shares of Common Stock which may be issued upon repurchase of Notes
will be issued out of the Company's authorized but unissued Common Stock and,
will upon issue, be duly and validly issued and fully paid and non-assessable
and free of any preemptive rights.

     If all of the conditions set forth in this Section 602 are not satisfied in
accordance with the terms thereof, the Repurchase Price shall be paid by the
Company only in cash.

 Section 603 Notices; Method of Exercising Repurchase Right, Etc.

     (1) Unless the Company shall have theretofore called for redemption all of
the Outstanding Notes, on or before the 30th day after the occurrence of a
Change in Control, the 

                                      22
<PAGE>
 
Company or, at the request and expense of the Company on or before the 15th day
after such occurrence, the Trustee, shall give to all Holders of Notes, in the
manner provided in Section 106 of the Indenture, notice (the "Company Notice")
of the occurrence of the Change in Control and of the repurchase right set forth
herein arising as a result thereof. 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)   the Repurchase Date,

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

            (iii) the Repurchase Price, and whether the Repurchase Price shall
                  be paid by the Company in cash or by delivery of shares of
                  Common Stock,

            (iv)  a description of the procedure which a Holder must follow to
                  exercise a repurchase right, and the place or places where
                  such Notes, are to be surrendered for payment of the
                  Repurchase Price and accrued interest, if any,

            (v)   that on the Repurchase Date the Repurchase Price, and accrued
                  interest, if any, will become due and payable upon each such
                  Note designated by the Holder to be repurchased, and that
                  interest thereon shall cease to accrue on and after said date,

            (vi)  the Conversion Rate then in effect, the date on which the
                  right to convert the principal amount of the Notes to be
                  repurchased will terminate and the place or places where such
                  Notes may be surrendered for conversion, and

            (vii) the place or places that the Note certificate with the
                  Election of Holder to Require Repurchase as specified in the
                  form of Note shall be delivered.

     No failure of the Company to give the foregoing notices or defect therein
shall limit any Holder's right to exercise a repurchase right or affect the
validity of the proceedings for the repurchase of Notes.

     If any of the foregoing provisions or other provisions of this Article Six
are inconsistent with applicable law, such law shall govern.

     (2) To exercise a repurchase right, a Holder shall deliver to the Trustee
on or before the 30th day after the date of the Company Notice (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 Notes to be repurchased (and, if
any Note is to repurchased in part, the serial number thereof, the portion of
the principal amount thereof to be repurchased and the name of the Person in
which the portion thereof to remain Outstanding after such repurchase is to be
registered) and a statement that an election to 

                                      23
<PAGE>
 
exercise the repurchase right is being made thereby, and, in the event that the
Repurchase Price shall be paid in shares of Common Stock, the name or names
(with addresses) in which the certificate or certificates for shares of Common
Stock shall be issued, and (ii) the Notes with respect to which the repurchase
right is being exercised. Such written notice shall be irrevocable, except that
the right of the Holder to convert the Notes with respect to which the
repurchase right is being exercised shall continue until the close of business
on the Business Day prior to the Repurchase Date.

     (3) In the event a repurchase right shall be exercised in accordance with
the terms hereof, the Company shall pay or cause to be paid to the Trustee the
Repurchase Price in cash or shares of Common Stock, as provided above, for
payment to the Holder on the Repurchase Date or, if shares of Common Stock are
to be paid, as promptly after the Repurchase Date as practicable, together with
accrued and unpaid interest to the Repurchase Date payable with respect to the
Notes as to which the repurchase right has been exercised; provided, however,
                                                           --------  ------- 
that installments of interest that mature on or prior to the Repurchase Date
shall be payable in cash to the Holders of such Notes, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Date.

     (4) If any Note (or portion thereof) surrendered for repurchase shall not
be so paid on the Repurchase Date, the principal amount of such Note (or portion
thereof, as the case may be) shall, until paid, bear interest to the extent
permitted by applicable law from the Repurchase Date at the rate of 7% per
annum, and each Note shall remain convertible into Common Stock until the
principal of such Note (or portion thereof, as the case may be) shall have been
paid or duly provided for.

     (5) Any Note which is to be repurchased only in part shall be surrendered
to the Trustee (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and make available for delivery to the Holder of such Note without service
charge, a new Note or Notes, containing identical terms and conditions, each in
an authorized denomination in aggregate principal amount equal to and in
exchange for the unrepurchased portion of the principal of the Note so
surrendered.

     (6) Any issuance of shares of Common Stock in respect of the Repurchase
Price shall be deemed to have been effected immediately prior to the close of
business on the Repurchase Date and the Person or Persons in whose name or names
any certificate or certificates for shares of Common Stock shall be issuable
upon such repurchase shall be deemed to have become on the Repurchase Date the
holder or holders of record of the shares represented thereby; provided,
                                                               -------- 
however, that any surrender for repurchase on a date when the stock transfer
- -------                                                                     
books of the Company shall be closed shall constitute the Person or Persons in
whose name or names the certificate or certificates for such shares are to be
issued as the record holder or holders thereof for all purposes at the opening
of business on the next succeeding day on which such stock transfer books are
open.  No payment or adjustment shall be made for dividends or distributions on
any Common Stock issued upon repurchase of any Note declared prior to the
Repurchase Date.

                                      24
<PAGE>
 
     (7) No fractions of shares shall be issued upon repurchase of Notes.  If
more than one Note shall be repurchased from the same Holder and the Repurchase
Price shall be payable in shares of Common Stock, the number of full shares
which shall be issuable upon such repurchase shall be computed on the basis of
the aggregate principal amount of the Notes so repurchased.  Instead of any
fractional share of Common Stock which would otherwise be issuable on the
repurchase of any Note or Notes, the Company will deliver to the applicable
Holder a check for the current market value of such fractional share.  The
current market value of a fraction of a share is determined by multiplying the
current market price of a full share by the fraction, and rounding the result to
the nearest cent. For purposes of this Section, the current market price of a
share of Common Stock is the Closing Price Per Share of the Common Stock on the
Trading Day immediately preceding the Repurchase Date.

     (8) Any issuance and delivery of certificates for shares of Common Stock on
repurchase of Notes shall be made without charge to the Holder of Notes being
repurchased for such certificates or for any tax or duty in respect of the
issuance or delivery of such certificates or the Notes represented thereby;
provided, however, that the Company shall not be required to pay any tax or duty
- --------  -------                                                               
which may be payable in respect of (i) income of the Holder or (ii) any transfer
involved in the issuance or delivery of certificates for shares of Common Stock
in a name other than that of the Holder of the Notes being repurchased, and no
such issuance or delivery shall be made unless and until the Person requesting
such issuance or delivery has paid to the Company the amount of any such tax or
duty or has established, to the satisfaction of the Company, that such tax or
duty has been paid.

     (9) All Notes delivered for repurchase shall be delivered to the Trustee to
be canceled at the direction of the Trustee, which shall dispose of the same as
provided in Section 309 of the Indenture.

 Section 604   Certain Definitions.

     For purposes of this Article Six,

percentage), other than any such acquisition by the Company, any Subsidiary of
the Company or any employee benefit plan of the Company existing on the date of
this Supplemental Indenture; or

          (ii)  any consolidation of the Company with, or merger of the Company
into, any other Person, any merger of another Person into the Company, or any
sale or transfer of all or substantially all of the assets (other than to a
wholly-owned subsidiary of the Company) of the Company to any other Person
(other than (a) any such transaction pursuant to which the holders of 50% or
more of the total voting power of all shares of capital stock of the Company

transaction have, directly or indirectly, at least 50% or more of the total
voting power of all shares of capital stock of the continuing or surviving
corporation entitled to vote generally in elections of directors of the
continuing or surviving corporation immediately after such transaction and (b) a
merger (x) which does not result in any reclassification, conversion, exchange
or cancellation of outstanding shares of capital stock of the Company or (y)
which is effected solely to change the jurisdiction of incorporation of the
Company and results in a reclassification, conversion or exchange of outstanding
shares of Common Stock into solely shares of common stock);

provided, however, that a Change in Control shall not be deemed to have occurred
- --------  -------                                                               
if either (a) the Closing Price Per Share of the Common Stock for any five
Trading Days within the period of 10 consecutive Trading Days ending immediately
after the later of the Change in Control or the public announcement of the
Change in Control (in the case of a Change in Control under clause 604(2)(i)
above) or the period of 10 consecutive Trading Days ending immediately before
the Change in Control (in the case of a Change in Control under clause
604(2)(ii) above) shall equal or exceed 105% of the Conversion Price of the
Notes in effect on each such Trading Day, or (b) all of the consideration
(excluding cash payments for fractional shares and cash payments made pursuant
to dissenters' appraisal rights) in a merger or consolidation constituting the
Change in Control described in clause 604(2)(i) and/or clause 604(2)(ii) above
consists of shares of common stock traded on a national securities exchange or
quoted on the Nasdaq National Market (or will be so traded or quoted immediately
following the Change in Control) and as a result of such transaction or
transactions the Notes become convertible solely into such common stock.

     (3) for purposes of Section 604(2)(i), the term "person" shall include any
syndicate or group which would be deemed to be a "person" under Section 13(d)(3)
of the Exchange Act, as in effect on the date of the original execution of this
Supplemental Indenture.

 Section 605   Consolidation, Merger, etc.

all or substantially all of the assets of the Company to which Section 1409
applies, in which the Common Stock of the Company is changed or exchanged as a
result into the right to receive shares of stock and other securities or
property or assets (including cash) which includes shares of Common Stock of the
Company or common stock of another Person that are, or upon issuance will be,
traded on a United States national securities exchange or approved for trading

time such change or exchange becomes effective in excess of 50% of the aggregate
fair market value of such shares of stock and other securities, property and
assets (including cash) (as determined by the Company, which determination shall
be conclusive and binding), then the Person formed by such consolidation or
resulting from such merger or combination or which acquires the properties or
assets (including cash) of the Company, as the case may be, shall execute and
deliver to the Trustee a supplemental indenture (which shall comply with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Supplemental Indenture relating to
the right of Holders to cause the Company to repurchase the Notes following a
Change in Control, including without limitation the applicable provisions of
this Article Six and the definitions of the Common Stock and Change in Control,
as appropriate, and such other related definitions set forth herein as
determined in good faith by the Company (which determination shall be conclusive
and binding), to make such provisions apply in the event of a subsequent Change
of Control to the common stock and the issuer thereof if different from the
Company and Common Stock of the Company (in lieu of the Company and the Common
Stock of the Company).

Notes a written notice specifying such default or breach and requiring it to be
remedied and stating that such notice is a "Notice of Default" hereunder.
