ITEM 9.  SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S.

        On September 24, 1997, Cypress Semiconductor Corporation, a Delaware
corporation (the "Company"), sold U.S.$175,000,000 aggregate principal amount of
its 6% Convertible Subordinated Notes due 2002 (the "Notes"), of which
U.S.$153,850,000 aggregate principal amount of Notes were sold in reliance upon
Rule 144A under the United States Securities Act of 1933, as amended (the
"Securities Act"), and U.S.$21,150,000 aggregate principal amount of Notes were
sold in reliance upon Regulation S under the Securities Act. The Notes were sold
by the Company to Deutsche Morgan Grenfell Inc., Prudential Securities
Incorporated and Robertson, Stephens & Company LLC (the "Initial Purchasers"),
pursuant to a Purchase Agreement, dated September 18, 1997 (the "Purchase
Agreement"), at a purchase price of 97.25% of the aggregate principal amount
thereof, plus accrued interest, if any, from September 24, 1997. The Initial
Purchasers' discount was 2.75% of the aggregate principal amount of the Notes,
for an aggregate discount of U.S.$4,812,500. Under the terms of the Purchase
Agreement, the Company has granted the Initial Purchasers an option exercisable
for 30 days to purchase up to an aggregate of U.S.$25,000,000 additional
principal amount of Notes solely to cover over-allotments, if any. The price to
investors for the Notes sold in the offering was 100% of the principal amount
thereof, plus accrued interest, if any, from September 24, 1997, for an
aggregate offering price of U.S.$175,000,000.

        The Notes were issued pursuant to the provisions of the Indenture, dated

Street Bank and Trust Company of California, N.A., as trustee thereunder. The
Notes will bear interest at the rate of 6% per annum until October 1, 2002. The
Notes are convertible into Common Stock, $.01 par value, of the Company at any
time prior to the close of business on the maturity date, unless previously
redeemed or repurchased, at a conversion price of $23.625 per share (equivalent
to a conversion rate of approximately 42.33 shares per $1,000 principal amount
of Notes), subject to adjustment in certain circumstances. The payment of
principal, premium, if any, interest, any Additional Amounts (as defined in the
Indenture), and any other amounts payable on or in respect of the Notes by the
Company are on a subordinated basis in accordance with the terms of the
Indenture.

        The Notes and the Common Stock issuable upon conversion of the Notes
have not been registered under the Securities Act, in reliance upon the
exemptions afforded by Rule 144A and Regulation S under the Securities Act.
Accordingly, the Notes and the Common Stock issuable upon conversion of the
Notes were offered and sold in the United States, in an aggregate principal
amount of U.S.$153,850,000, only to qualified institutional buyers in reliance
upon Rule 144A under the Securities Act, and outside the United States to
non-United States investors, in an aggregate principal amount of
U.S.$21,150,000, in reliance upon Regulation S under the Securities Act.

        The Company has agreed to file, within 90 days following the last
original issue date of the Notes, a shelf registration statement in respect of
Common Stock issuable upon conversion of the Notes, pursuant to a Registration
Rights Agreement dated as of September 15, 1997, by and among the Company and

record of Holders of Securities voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities duly
called and held in accordance with the provisions of Article Nine or (3) a

records delivered to the Trustee with a courtesy copy to Company's counsel at
the address listed in Section 1.5 and if pertaining to any conversion notice,
with a courtesy copy to Company's common stock transfer agent at the address

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

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

        (d) The fact and date of execution of any such instrument or writing and

<PAGE>   22



action, or, in the case of any such vote, prior to such vote, the record date
for any such action or vote shall be the 30th day (or, if later, the date of the
most recent list of Holders required to be provided pursuant to Section 15.1)
prior to such first solicitation or vote, as the case may be. With regard to any
record date, the Holders on such date (or their duly appointed agents or
proxies), and only such Persons, shall be entitled to give or take, or vote on,
the relevant action, whether or not such Holders remain Holders after such
record date. Notwithstanding the foregoing, the Company shall not set a record
date for, and the provisions of this paragraph shall not apply with respect to,
any notice, declaration or direction referred to in the next paragraph.

        Upon receipt by the Trustee from any Holder of (i) any notice of default
or breach referred to in Section 5.1(3), if such default or breach has occurred
and is continuing and the Trustee shall not have given such a notice to the
Company, (ii) any declaration of acceleration referred to in Section 5.2, if an
Event of Default has occurred and is continuing and the Trustee shall not have
given such a declaration to the Company, or (iii) any direction referred to in
Section 5.12, if the Trustee shall not have taken the action specified in such
direction, then a record date shall automatically and without any action by the
Company or the Trustee be set for determining the Holders entitled to join in
such notice, declaration or direction, which record date shall be the close of
business on the tenth day (or, if such day is not a Business Day, the first
Business Day thereafter) following the day on which the Trustee receives such
notice, declaration or direction. Promptly after such receipt by the Trustee,
and as soon as practicable thereafter, the Trustee shall notify the Company and
the Holders of any such record date so fixed. The Holders on such record date
(or their duly appointed agents or proxies), and only such Persons, shall be
entitled to join in such notice, declaration or direction, whether or not such
Holders remain Holders after such record date; provided that, unless such
notice, declaration or direction shall have become effective by virtue of
Holders of the requisite principal amount of Securities on such record date (or
their duly appointed agents or proxies) having joined therein on or prior to the
90th day after such record date, such notice, declaration or direction shall
automatically and without any action by any Person be canceled and of no further
effect. Nothing in this paragraph shall be construed to prevent a Holder (or a
duly appointed agent or proxy thereof) from giving, before or after the
expiration of such 90-day period, a notice, declaration or direction contrary to
or different from, or, after the expiration of such period, identical to, the
notice, declaration or direction to which such record date relates, in which
event a new record date in respect thereof shall be set pursuant to this
paragraph. In addition, nothing in this paragraph shall be construed to render
ineffective any notice, declaration or direction of the type referred to in this
paragraph given at any time to the Trustee and the Company by Holders (or their
duly appointed agents or proxies) of the requisite principal amount of
Securities on the date such notice, declaration or direction is so given.

        (f) Any request, demand, authorization, direction, notice, consent,
election, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Successor 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.

given and received by Holders when such notice is mailed, whether or not such
Holder receives such notice.

        In any case where notice to Holders of Securities is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder of a Security shall affect the sufficiency of such
notice with respect to other Holders of Securities given as provided above. In
case by reason of the suspension of or irregularities in regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification to Holders of Securities as shall be made with the
approval of the Trustee, which approval shall not be unreasonably withheld,
shall constitute a sufficient notification to such Holders for every purpose
hereunder.

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

SECTION 1.7.  Effect of Headings and Table of Contents.

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

SECTION 1.8.  Successors and Assigns.

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

SECTION 1.9.  Separability Clause.

        In case any provision in this Indenture or 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 1.10.  Benefits of Indenture.

        Except as provided in the next sentence, nothing in this Indenture or in
the Securities, express or implied, shall give to any Person, other than the
parties hereto and their successors and assigns hereunder and the Holders of
Securities, any benefit or legal or equitable right, remedy or claim under this
Indenture. The provisions of Article Thirteen are intended to be for the benefit
of, and shall be enforceable directly by, the holders of Senior Indebtedness of
the Company.

SECTION 1.11.  Governing Law.

        THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, THE UNITED STATES OF AMERICA,
WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

SECTION 1.12.  Legal Holidays.

        In any case where any Interest Payment Date, Redemption Date, Repurchase
Date or Stated Maturity of any Security or the last day on which a Holder of a
Security has a right to convert his Security shall not be a Business Day at any
Place of Payment or Place of Conversion, as the case may be, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal and premium, if any, or delivery for conversion
of such Security need not be made at such Place of Payment or Place of
Conversion, as the case may be, on or by such day, but may be made on or by the
next succeeding Business Day at such Place of Payment or Place of Conversion, as
the case may be, with the same force and effect as if made on the Interest
Payment Date, Redemption Date or Repurchase Date, or at the Stated Maturity or
by such last day for conversion; provided, however, that in the case that
payment is made on such succeeding Business Day, no interest shall accrue on the
amount so payable for the period from and after such Interest Payment Date,
Redemption Date, Repurchase Date, Stated Maturity or last day for conversion, as
the case may be.

SECTION 1.13.  Conflict with Trust Indenture Act.

        If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under the Trust Indenture Act to be
a part of and to govern this Indenture, the latter provision shall control. If
any provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be. Until such time as this Indenture shall be qualified under the Trust
Indenture Act, this Indenture, the Company and the Trustee shall be deemed for
all purposes hereof to be subject to and governed by the Trust Indenture Act to
the same extent as would be the case if this Indenture were so qualified on the
date hereof.

SECTION 1.14.  Jurisdiction.

        (a) The Company hereby irrevocably and unconditionally submits to the
non-exclusive jurisdiction of any New York State or United States Federal court
sitting in New York City over any suit, action or proceeding arising out of or
relating to this Indenture or any Security. The Company irrevocably and
unconditionally waives, to the fullest extent permitted by law, any objection
which it may now or hereafter have to the laying of the venue of any such suit,
action or proceeding brought in such a court and any claim that any such suit,
action or proceeding brought in such a court has been brought in an inconvenient
forum. To the extent that the Company has or hereafter may acquire any immunity
from jurisdiction of any court or from any legal process with respect to itself
or its property, the Company irrevocably waives such immunity in respect of its
obligations under the Indenture or any Security. The Company agrees that final
judgment in any such suit, action or proceeding brought in such a court shall be
conclusive and binding upon the Company, and, to the extent permitted by
applicable law, may be enforced in any court to the jurisdiction of which the
Company is subject by a suit upon such judgment or in any manner provided by
law; provided that service of process is effected upon the Company in the manner
specified in the following subsection or as otherwise permitted by law.

        (b) As long as any of the Securities remain outstanding, the Company
will at all times have an authorized agent in New York City, upon whom process
may be served in any legal action or proceeding arising out of or relating to
this Indenture or any Security. Service of process upon such agent and written
notice of such service mailed or delivered to the Company shall to the fullest
extent permitted by law be deemed in every respect effective service of process
upon the Company in any such legal action or proceeding. The Company hereby
irrevocably appoints the CT Corporation System, 1633 Broadway, New York, New
York 10019 as its agent for such purpose, and covenants and agrees that service
of process in any suit, action or proceeding may be made upon it at such office
of such agent. Notwithstanding the foregoing, the Company may, with prior
written notice to the Trustee, terminate the appointment of such agent and
appoint another agent for the above purposes so that the Company shall at all
times have an agent for the above purposes in New York City.

SECTION 1.15.  Indenture and Securities Solely Corporate Obligations.

        No recourse for the payment of the principal of or premium, if any, or
interest (including any Additional Amounts or Liquidated Damages) on any
Security 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, 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 waived and released
as a condition of, and as a consideration for, the execution of this Indenture
and the issue of the Securities.

Cypress Semiconductor Corporation, a Delaware corporation (herein called the
"Company", which term includes any successor Person under the Indenture
referred to on the reverse hereof), for value received, hereby promises to pay
to _______________, or registered assigns (the "Holder"), the principal sum of
_____________ United States Dollars (U.S.$_____) [(which amount may from time
to time be increased or decreased to such other principal amounts (which, taken
together with the principal amounts of all other Outstanding Securities, shall
not exceed $200,000,000 in the aggregate at any time) by adjustments made on
the records of the Trustee, as Custodian of the Depositary, in accordance
with the rules and procedures of the Depositary)](1) on October 1, 2002 and to
pay interest thereon, from September 24, 1997, or from the most recent Interest
Payment Date (as defined below) to which interest has been paid or duly
provided for, semi-annually in arrears on April 1 and October 1 in each year
(each, an "Interest Payment Date"), commencing April 1, 1998, at the rate of 6%
per annum (together with any Additional Amounts and Liquidated Damages that the
Company may be required to pay) until the principal hereof is due, and at a
rate of 6% per annum on any overdue principal and premium, if any, and, to the
extent permitted by law, on any overdue interest.

        The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the 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 March 15 or September 15 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Except as
otherwise provided in the Indenture, any such interest not so punctually paid or
duly provided for ("Defaulted Interest") 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 Company, notice whereof shall be given to
Holders of Securities 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 may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture. Payments of principal shall be made upon the
surrender of this Security, at the Corporate Trust Office of the Trustee in Los
Angeles, California or at the office or agency of the Trustee in the Borough of

by it for such purpose in the Borough of Manhattan, The City of New York in such
coin or currency of the United States of America as at the time of payment shall
be legal tender for the payment of public and private debts, or at such other
offices or agencies as the Company may designate, by United States Dollar check
drawn on a bank in the United States, or transfer to a United States Dollar
account (such a transfer to be made only to a Holder of an aggregate principal
amount of Securities in excess of U.S. $2,000,000, and only if such Holder shall
have furnished wire instructions in writing to the Trustee no later than 15 days
prior to the relevant payment date) maintained by the Holder with a bank in the
United States. Payment of interest on this Security may be made by United States
Dollar check mailed to the address of the Person entitled thereto as such
address shall appear in the Note Register, or, upon written application by the
Holder to the Security Registrar setting forth wire instructions not later than
the relevant Record Date, by transfer to a United States Dollar account (such a
transfer to be made only to a Holder of an aggregate principal amount of
Securities in excess of U.S.$2,000,000 and only if such Holder shall have
furnished wire instructions in writing to the Trustee no later than 15 days
prior to the relevant payment date) maintained by the Holder with a bank in the
United States.

        The Company will pay to the Holder of this Security who is a Non-U.S.
Holder such additional amounts ("Additional Amounts") as may be necessary in
order that every net payment of the principal of, premium, if any, and interest
on this Security (including payment on redemption or repurchase), after
deduction or withholding for or on account of any present or future tax,
assessment or governmental charge imposed upon or as a result of such payment by
the United States of America or any political subdivision or taxing authority
thereof or therein (each, a "Taxing Jurisdiction"), will not be less than the
amount provided for in this Security to be then due and payable; provided,
however, that the Company shall not be obligated to pay any Additional Amounts
in respect of payments becoming due on the Securities more than 15 days after
the Redemption Date with respect to any redemption of the Tax Affected
Securities pursuant to the fourth paragraph of the reverse of this Security to
the extent that the Company's obligation to pay such Additional Amounts arises
from the Tax Law Change that resulted in such redemption; and provided, further,
that the foregoing obligation to pay Additional Amounts will not apply to:

               (a) any tax, assessment or other governmental charge which would
        not have been so imposed but for (i) the existence of any present or
        former connection between such Non- U.S. Holder (or between a fiduciary,
        settlor, beneficiary, member, shareholder of or possessor of a power
        over such Non-U.S. Holder, if such Non-U.S. Holder is an estate, a
        trust, a partnership or a corporation) and the Taxing Jurisdiction,
        including, without limitation, such Non-U.S. Holder (or such fiduciary,
        settlor, beneficiary, member, shareholder or possessor) being or having
        been a citizen, domiciliary or resident of the United States or treated
        as a resident thereof, or being or having been engaged in trade or
        business or present

        therein, or having or having had a permanent establishment therein or
        (ii) such Non-U.S. Holder's present or former status as a personal
        holding company, a foreign personal holding company with respect to the
        United States, a controlled foreign corporation, a passive foreign
        investment company, or a foreign private foundation or foreign tax
        exempt entity for United States federal tax purposes, or a corporation
        which accumulates earnings to avoid United States federal income tax;

               (b) any tax, assessment or other governmental charge which would
        not have been so imposed but for the presentation by the Non-U.S. Holder
        of this Security for payment on a date more than 15 days after the date
        on which such payment became due and payable or the date on which
        payment thereof is duly provided for, whichever occurs later;

               (c) any estate, inheritance, gift, sales, transfer, personal
        property or similar tax, assessment or governmental charge;

               (d) any tax, assessment or other governmental charge which would
        not have been imposed but for the failure to comply with a request by
        the Company addressed to such Non- U.S. Holder (or such fiduciary,
        settlor, beneficiary, member, shareholder or possessor) to provide any
        certification, identification or other reporting concerning the
        nationality, residence, identity or connection with the United States of
        such Non-U.S. Holder (or beneficial owner of such Security), if
        compliance is required or imposed by a statute, treaty, regulation or
        administrative practice of the United States or any political
        subdivision or taxing authority thereof or therein as a precondition to
        exemption from all or part of such tax, assessment or other governmental
        charge;

               (e) any tax, assessment or other governmental charge which is
        payable otherwise than by deduction or withholding from payments of
        principal of, premium, if any, or interest on such Security;

               (f) any tax, assessment or other governmental charge imposed on
        interest received by a Non-U.S. Holder actually or constructively
        holding 10% or more of the total combined voting power of all classes of
        stock of the Company entitled to vote;

               (g) any tax, assessment or other governmental charge imposed on a
        Non-U.S. Holder that is a partnership or a fiduciary or other than the
        sole beneficial owner of such payment, but only to the extent that any
        beneficial owner or member of the partnership or beneficiary or settlor
        with respect to the fiduciary would not have been entitled to the
        payment of Additional Amounts had the beneficial owner, member,
        beneficiary or settlor directly been the Holder of this Security; or

               (h) any combination of items (a), (b), (c), (d), (e), (f) and

        Except as specifically provided herein and in the Indenture, the Company
shall not be required to make any payment with respect to any tax, assessment or
other governmental charge imposed by any government or any political subdivision
or taxing authority thereof or therein. Whenever in this Security there is a
reference, in any context, to the payment of the principal of, premium, if any,
or interest on, or in respect of, any Security such mention shall be deemed to
include mention of the payment of Additional Amounts payable as described in the
preceding paragraph to the extent that, in such context, Additional Amounts are,
were or would be payable in respect of such Security and express mention of the
payment of Additional Amounts (if applicable) in any provisions of this Security
shall not be construed as excluding Additional Amounts in those provisions of
this Security where such express mention is not made.

        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. Capitalized terms used
herein, including on the reverse hereof, and not defined herein or on the
reverse hereof shall have the respective meanings given to such terms in the
Indenture.

Trustee referred to on the reverse hereof or an Authenticating Agent by the
manual signature of one of their respective authorized signatories, this
Security shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

                                [FORM OF REVERSE]

        This Security is one of a duly authorized issue of securities of the
Company designated as its "6% Convertible Subordinated Notes due 2002" (herein
called the "Securities"), limited in aggregate principal amount to U.S.
$200,000,000, issued and to be issued under and pursuant to an Indenture, dated
as of September 15, 1997 (herein called the "Indenture"), between the Company
and State Street Bank and Trust Company of California, N.A., Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee, the holders of
Senior Indebtedness of the Company and the Holders of the Securities and of the
terms upon which the Securities are, and are to be, authenticated and delivered.
The Securities are issuable in the denomination of U.S.$1,000 and integral
multiples thereof. As provided in the Indenture and subject to the limitations
therein set forth, the Securities are exchangeable at the Corporate Trust Office
of the Trustee, or the office or agency of the Trustee, or at such other office
or agency of the Company as may be designated by it for such purpose, in The
City of New York (each a "Note Registrar").

        No sinking fund is provided for the Securities. The Securities will not
be redeemable at the option of the Company prior to October 3, 2000. At any time
on or after October 3, 2000, and prior to maturity, the Securities are subject
to redemption at the option of the Company at any time, in whole or in part, at
the following Redemption Prices (expressed as percentages of the principal
amount) upon not less than 20 nor more than 60 days' notice to the Holders prior
to the Redemption Date.

        If redeemed during the 12-month period beginning October 1 (beginning
October 3, 2000 and ending September 30, 2001, in the case of the first such
period):

and 100% at October 1, 2002, together, in each case, with accrued interest to,
but excluding, the Redemption Date; provided that Securities that are Tax
Affected Securities are also redeemable, in whole but not in part, under the
circumstances described in the next succeeding paragraph, at a Redemption Price
equal to 100% of the principal amount thereof plus interest accrued to, but
excluding, the Redemption Date; provided, however, that interest installments on
Securities 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.

        If the Company determines that, principally as a result of a Tax Law
Change, the Company is or would become obligated to pay Additional Amounts to
the Holder of any Security, as described



                                      -26-

<PAGE>   35



in the third paragraph of the face of this Security, and such obligation cannot
be avoided by the Company taking reasonable measures available to it, then the
Company may, at its option, redeem the Tax Affected Securities in whole, but not
in part, at any time, on giving not less than 20 days' notice to the Holders
prior to the Redemption Date, at a Redemption Price equal to 100% of the
principal amount plus interest accrued to, but excluding, the Redemption Date
and any Additional Amounts then payable; provided, that no such notice of
redemption shall be given earlier than 90 days prior to the earliest date on
which the Company would be obligated to pay any such Additional Amounts were a
payment in respect of the Tax Affected Securities then made. Prior to the
publication of any notice of redemption pursuant to this paragraph, the Company
shall deliver to the Trustee (a) an Officers' Certificate stating that the
Company is entitled to effect such redemption and setting forth a statement of
facts showing that the conditions precedent to the right of the Company so to
redeem have occurred and (b) an Opinion of Counsel of recognized standing
selected by the Company and reasonably acceptable to the Trustee to the effect
that the circumstances referred to above in this paragraph exist. The Trustee
shall accept such opinion as sufficient evidence of the satisfaction of the
conditions precedent described above, in which event it shall be conclusive and
binding on the Holders. The Company's right to redeem the Tax Affected
Securities shall continue as long as the Company is obligated to pay such
Additional Amounts, notwithstanding that the Company shall have made payments of
Additional Amounts specified in such third paragraph.

        In the event of a redemption of less than all of the Securities, the
Company will not be required (a) to register the transfer or exchange of
Securities for a period of 15 days immediately preceding the date notice is
given identifying the serial numbers of the Securities called for such
redemption or (b) to register the transfer or exchange of any Security, or
portion thereof, called for redemption.

        In any case where the due date for the payment of the principal or
premium, if any, or interest, including Additional Amounts and Liquidated
Damages on, any Security or the last day on which a Holder of a Security has a
right to convert his Security shall be, at any Place of Payment or Place of
Conversion, as the case may be, a day on which banking institutions at such
Place of Payment or Place of Conversion are authorized or obligated by law or
executive order to close, then payment of principal, premium, if any, or
interest, including Additional Amounts and Liquidated Damages, or delivery for
conversion of such Security need not be made on or by such date at such place
but may be made on or by the next succeeding day at such place which is not a
day on which banking institutions are authorized or obligated by law or
executive order to close, with the same force and effect as if made on the date
for such payment or the date fixed for redemption or repurchase, or by such last
day for conversion, and no interest shall accrue on the amount so payable for
the period after such date.

        Subject to and upon compliance with the provisions of the Indenture, the
Holder of this Security is entitled, at his option, at any time prior to the
close of business on October 1, 2002, or in case this Security or a portion
hereof is called for redemption or the Holder hereof has exercised his right to
require the Company to repurchase this Security, or such portion hereof, then in
respect of this Security until and including, but (unless the Company defaults
in making the payment due upon



                                      -27-

<PAGE>   36



redemption or repurchase, as the case may be) not after, the close of business
on the Business Day next preceding the Redemption Date or the Repurchase Date,
as the case may be, to convert this Security (or any portion of the principal
amount hereof that is an integral multiple of U.S.$1,000, provided that the
unconverted portion of such principal amount is U.S.$1,000 or any integral
multiple thereof) into fully paid and nonassessable Common Stock of the Company
at an initial Conversion Price of U.S. $23.625 for each share of Common Stock
(or at the then current adjusted Conversion Price if an adjustment has been made
as provided in the Indenture).

        In order to convert such Security, a Holder must surrender this
Security, duly endorsed or assigned to the Company or in blank and, in case such
surrender shall be made during the period from the close of business of any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date ("Interest Period") (except Securities
called for redemption on a Redemption Date or to be repurchased on a Repurchase
Date during, in each case, such Interest Period), also accompanied by payment in
New York Clearing House or other 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, and also the conversion notice
hereon duly executed, to the Company at the Corporate Trust Office of the
Trustee in Los Angeles, California, or the office or agency of the Trustee in
the Borough of Manhattan, The City of New York or at such other office or agency
of the Company, subject to any laws or regulations applicable thereto and
subject to the right of the Company to terminate the appointment of any
Conversion Agent (as defined below) as may be designated by it for such purpose
in the Borough of Manhattan, The City of New York, or at such other offices or
agencies as the Company may designate (each a "Conversion Agent"), provided
further, that if this Security or portion hereof has been called for redemption
on a Redemption Date or is repurchasable on a Repurchase Date occurring, in
either case, during the Interest Period and is surrendered for conversion during
such Interest Period, then the Holder of this Security who converts this
Security or a portion hereof during such Interest Period will be entitled to
receive the interest accruing hereon from the Interest Payment Date next
preceding the date of such conversion to such succeeding Interest Payment Date
and shall not be required to pay such interest upon surrender of this Security
for conversion. 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, no cash payment or adjustment
is to be made on conversion, if the date of conversion is not an Interest
Payment Date, for interest accrued hereon from the Interest Payment Date next
preceding the date of conversion, or for dividends on the Common Stock issued on
conversion hereof. The Company shall thereafter deliver to the Holder the fixed
number of shares of Common Stock (together with any cash adjustment, as provided
in the Indenture) into which this Security is convertible and such delivery will
be deemed to satisfy the Company's obligation to pay the principal amount of
this Security. No fractions of shares or scrip representing fractions of shares
will be issued on conversion, but instead of any fractional interest (calculated
to the nearest 1/100th of a share) the Company shall pay a cash adjustment 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 (other than a
consolidation or merger



                                      -28-

<PAGE>   37



which does not result in any reclassification, conversion, exchange or
cancellation of the Common Stock) or the transfer of all or substantially all of
the property and 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 such consolidation, merger
or transfer by a holder of the number of shares of Common Stock of the Company
into which this Security could have been converted immediately prior to such
consolidation, merger or transfer (assuming such holder of Common Stock is not a
Constituent Person and 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). No adjustment in the Conversion Price will be made until such
adjustment would require an increase or decrease of at least one percent of such
price, provided that any adjustment that would otherwise be made will be carried
forward and taken into account in the computation of any subsequent adjustment.

        Subject to certain limitations in the Indenture, at any time when the
Company is not subject to Section 13 or 15(d) of the United States Securities
Exchange Act of 1934, as amended, upon the request of a Holder of a Restricted
Security or the holder of Common Stock issued upon conversion thereof, the
Company will promptly furnish or cause to be furnished Rule 144A Information to
such Holder of Restricted Securities or such holder of Common Stock issued upon
conversion of Restricted Securities, or to a prospective purchaser of any such
security designated by any such Holder or holder, as the case may be, to the
extent required to permit compliance by such Holder or holder with Rule 144A
under the Securities Act in connection with the resale of any such security.

        The Holder of this Security and the Common Stock issuable upon
conversion thereof is entitled to the benefits of a Registration Rights
Agreement (subject to the provisions thereof), dated as of September 15, 1997,
between the Company and the Initial Purchasers.

        If a Fundamental Change (as defined in the Indenture) occurs at any time
on or prior to October 1, 2002, each Holder shall have the right, at such
Holder's option, to require the Company to repurchase all of such Holder's
Securities (or any portion of such Securities that is $1,000 or an integral
multiple of $1,000 in excess thereof) on the 45th day after notice thereof. Such
payment shall be made at the following Repurchase Prices (expressed as
percentages of the principal amount thereof) in the event of a Fundamental
Change occurring during the 12-month period beginning October 1:

and 100% at October 1, 2002; provided in each case that if the Applicable Price
(as defined in the Indenture) is less than the Reference Market Price (as
defined in the Indenture), the Company shall



                                      -29-

<PAGE>   38



repurchase such Securities at a price equal to the foregoing Repurchase Price
multiplied by the fraction obtained by dividing the Applicable Price by the
Reference Market Price. In each case, the Company shall also pay accrued
interest, if any, on such Securities to, but excluding the Repurchase Date;
provided that if such Repurchase Date is April 1 or October 1, then the interest
payable on such date shall be paid to the Holder of record of the Securities on
the Regular Record 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 in those provisions of this Security when such express mention is not
made.

        [The following paragraph shall appear in each Security that is not a
Global Security:

        In the event of redemption, repurchase or conversion of this Security in
part only, a new Security or Securities for the unredeemed, unrepurchased or
unconverted portion hereof will be issued in the name of the Holder hereof.]

        [The following paragraph shall appear in the Global Security:

        In the event of a deposit or withdrawal of an interest in this Security,
including an exchange, transfer, redemption, repurchase or conversion of this
Security in part only, the Trustee, as Custodian of the Depositary, shall make
an adjustment on its records to reflect such deposit or withdrawal in accordance
with the rules and procedures of the Depositary.]

        The indebtedness evidenced by this Security and the obligations of the
Company under the Indenture are 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 Indebtedness (as defined in the Indenture) 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 an Event of Default (as defined in the Indenture) shall occur and be
continuing, the principal of all the Securities, together with accrued interest
to the date of declaration, may be declared due and payable in the manner and
with the effect provided in the Indenture. Upon payment (i) of the amount of
principal so declared due and payable, together with accrued interest and
premium, if any, Additional Amounts, if any, and Liquidated Damages, if any, to
the date of declaration, and (ii) of interest on any overdue principal and
overdue interest, to the extent permitted by law, all of the Company's
obligations in respect of the payment of the principal of and interest on the
Securities 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 under the Indenture at
any time by the Company and the Trustee with either (a) the written consent of
the Holders of not less than a majority in aggregate principal amount of the
Securities at the time Outstanding (as defined in the Indenture), or (b) by the
adoption of a resolution, at a meeting of Holders of the Outstanding Securities
at which a quorum is present, by the Holders of at least the lesser of (i) a
majority in aggregate principal amount of the Securities at the time Outstanding
and (ii) 66-2/3% in aggregate principal amount of the Outstanding Securities
represented and entitled to vote at such meeting. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, 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 Successor Security to this Security, whether or not
notation of such consent or waiver is made upon this Security or such other
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 (a) such Holder shall have previously
given the Trustee written notice of a continuing Event of Default, (b) the
Holders of not less than 25% in aggregate principal amount of the Securities
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 aggregate principal amount of the Securities
Outstanding a direction inconsistent with such request, and (c) 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, premium, if any, or interest hereon (including any
Additional Amounts and Liquidated Damages) on or after the respective due dates
expressed herein or for the enforcement of the right to convert this Security as
provided in the Indenture.

        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, premium, if any, and
interest on (including Additional Amounts and Liquidated Damages, as described
herein) this Security at the times, places and rate, and in the coin or
currency, herein prescribed or to convert this Security as provided in the
Indenture.

        As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of Securities is registrable on the Note Register (as
defined in the Indenture) upon surrender of a Security for registration of
transfer (a) at the Corporate Trust Office of the Trustee or at the office or
agency of the Trustee in the Borough of Manhattan or at such other office or
agency of the Company as may be designated by it for such purpose in the Borough
of Manhattan, The City of New York, or (b) subject to any laws or regulations
applicable thereto and to the right of the Company to

terminate the appointment of any Note Registrar, at the offices of the Note
Registrars described herein or at such other offices or agencies as the Company
may designate, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Note Registrar duly
executed by, the Holder thereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees by the Note Registrar. 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 recover any tax or other governmental charge payable in
connection therewith.

        No recourse for the payment of the principal (and premium, if any) or
interest (including any Additional Amounts or Liquidated Damages) on this
Security and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto 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, all such
liability being, by the acceptance hereof and as part of consideration for the
issue hereof, expressly waived and released.

        Prior to due presentation 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 thereof for
all purposes, whether or not such Security be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

        THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA,
WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

Officer, its President or one of its Senior Vice Presidents or one of its Vice
Presidents, under an impression of its corporate seal or a facsimile of its

Assistant Treasurers or Secretary or one of its Assistant Secretaries. Any such
signature may be manual or facsimile.

        Securities bearing the manual or facsimile signature of an individual or

this Indenture, the Company may deliver Securities executed by the Company to
the Trustee or to its order for authentication (or to the Paying Agent),

Securities, and the Trustee or an Authenticating Agent in accordance with such

        Each Security shall be dated the date of its authentication.

        In authenticating the Securities and in accepting the additional
responsibilities under the Indenture in relation to such Securities, the Trustee
shall be entitled to receive and shall be fully protected in relying upon, an
Opinion of Counsel stating that:

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

               (b) the terms of such Securities have been established in
conformity with the provisions of this Indenture;

               (c) such Securities, when completed by appropriate insertions and
executed and delivered by the Company to the Trustee for authentication in
accordance with this Indenture, authenticated and delivered by the Trustee in
accordance with this Indenture and issued by the Company in the manner and
subject to any conditions specified in such Opinion of Counsel, will constitute
the legal, valid and binding obligations of the Company, enforceable in
accordance with their terms, subject to applicable bankruptcy, insolvency,
reorganization and other similar laws of general applicability relating to or
affecting the enforcement of creditors' rights, to general equitable principles
and to such other qualifications as such counsel shall conclude do not
materially affect the rights of Holders of such Securities;

               (d) all laws and requirements in respect of the execution and
delivery by the Company of such Securities and of the supplemental indenture, if
any, have been complied with and that authentication and delivery of such
Securities and the execution and delivery of the supplemental indenture, if any,
by the Trustee will not violate the terms of the Indenture;

               (e) the Company has the corporate power to issue such Securities,
and has duly taken all necessary corporate action with respect to such issuance;
and

               (f) the issuance of such Securities will not contravene the
articles of incorporation or by-laws of the Company or result in any violation
of any of the terms or provisions of any law or regulation or of any indenture,
mortgage or other agreement by which the Company is bound known to such Counsel,
which violation would have a material adverse effect on the Company.

        The Trustee shall not be required to authenticate and deliver any 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.

        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 or an Authenticating Agent by manual signature



                                      -39-

of an authorized signatory, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder is entitled to the benefits of this
Indenture.

        Any Global Security shall represent such of the outstanding Securities
as shall be specified therein and shall provide that it shall represent the
aggregate amount of outstanding Securities from time to time endorsed thereon
and that the aggregate amount of outstanding Securities represented thereby may
from time to time be increased or reduced to reflect transfers or exchanges
permitted hereby. Any endorsement of a Global Security to reflect the amount of
any increase or decrease in the amount of outstanding Securities represented
thereby shall be made by the Trustee or the Custodian, at the direction of the
Trustee, in such manner and upon instructions given by the holder of such
Securities in accordance with this Indenture. Payment of principal of and
interest and premium, if any, on any Global Security shall be made to the Holder
of such Global Security.

SECTION 3.4.  Registration, Registration of Transfer and Exchange; Restrictions
              on Transfer.

               (a) 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 designated pursuant to Section 10.2
(including the office or agency of State Street Bank and Trust Company of
California, N.A., in the Borough of Manhattan, The City of New York) being
herein sometimes collectively referred to as the "Note 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.

        Upon surrender for registration of transfer of any Security at an office
or agency of the Company designated pursuant to Section 10.2 for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Securities
of any authorized denominations and of a like aggregate principal amount and
tenor and bearing such restrictive legends as may be required by this Indenture.

        At the option of the Holder, and subject to the further provisions of
this Section 3.4, Securities may be exchanged for other Securities of any
authorized denomination and of a like aggregate principal amount, upon surrender
of the Securities to be exchanged at any such office or agency maintained by the
Company pursuant to Section 10.2. Whenever any Securities are so surrendered for
exchange, and subject to the further provisions of this Section 3.4, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive. Every Security
presented or surrendered for registration of transfer or for exchange shall (if
so required by the Company or the Note Registrar) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Note Registrar duly executed, by the Holder thereof or his
attorney duly authorized in writing.

        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, subject to the other provisions of



                                      -40-

<PAGE>   49



this Section 3.4, entitled to the same benefits, under and subject to the same
restrictions imposed by this Indenture, as the Securities surrendered upon such
registration of transfer or exchange.

        Except as provided in Section 3.6, no service charge shall be made to a
Holder 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
8.5, 11.8, 12.2 or 14.2(e) (other than, in the case of Securities, where the
Common Stock is to be issued or delivered in a name other than that of the
Holder of the Security) not involving any transfer and other than any stamp and
other duties, if any, which may be imposed in connection with any such transfer
or exchange by the United States or any political subdivision thereof or
therein, which shall be paid by the Company.

        In the event of a redemption of the Securities in part, neither the
Company nor the Note Registrar will be required (a) to register the transfer of
or exchange of Securities for a period of 15 days immediately preceding the date
notice is given identifying the serial numbers of the Securities called for such
redemption or (b) to register the transfer of or exchange any Security, or
portion thereof, called for redemption.

               (b) So long as the Securities are eligible for book-entry
settlement with the Depositary, or unless otherwise required by law, all
Securities that are so eligible may be represented by one or more Global
Securities registered in the name of the Depositary or the nominee of the
Depositary, except as otherwise specified below. The transfer and exchange of
beneficial interests in any such Global Security shall be effected through the
Depositary in accordance with this Indenture and the procedures of the
Depositary therefor.

        Securities that upon initial issuance are beneficially owned by QIBs
will be represented by a Global Security (the "Rule 144A Global Security") and
Securities that upon initial issuance are beneficially owned by Non-U.S. Persons
will be represented by another Global Security (the "Regulation S Global
Security"). Transfers of interests in the Securities between the Rule 144A
Global Security and the Regulation S Global Security will be made in accordance
with the standing instructions and procedures of the Depositary and its
participants. The Trustee shall make appropriate endorsements to reflect
increases or decreases in the principal amounts of such Global Securities as set
forth on the face of the Security ("Principal Amount") to reflect any such
transfers.

        Except as provided below, beneficial owners of a Global Security shall
not be entitled to have certificates registered in their names, will not receive
or be entitled to receive physical delivery of certificates in definitive form
and will not be considered Holders of such Global Securities.

               (c) So long as the Securities are eligible for book-entry
settlement, or unless otherwise required by law, upon any transfer of a
definitive Security to a QIB in accordance with Rule 144A or to a Non-U.S.
Person in accordance with Regulation S, and upon receipt of the definitive
Security or Securities being so transferred, together with a certification,
substantially in the



                                      -41-

<PAGE>   50



form on the reverse of the Security, from the transferor that the transfer is
being made in compliance with Rule 144A or Regulation S, as the case may be (or
other evidence satisfactory to the Trustee), the Trustee shall make an
endorsement on the Rule 144A Global Security or the Regulation S Global
Security, as the case may be, to reflect an increase in the aggregate Principal
Amount of the Securities represented by such Global Security, the Trustee shall
cancel such definitive Security or Securities in accordance with the standing
instructions and procedures of the Depositary, the aggregate Principal Amount of
Securities represented by such Global Security to be increased accordingly;
provided that no definitive Security, or portion thereof, in respect of which
the Company or an Affiliate of the Company held any beneficial interest shall be
included in such Global Security until such definitive Security is freely
tradable in accordance with Rule 144(k); provided further that the Trustee shall
issue Securities in definitive form upon any transfer of a beneficial interest
in the Global Security to the Company or any Affiliate of the Company.

        Upon any sale or transfer of a Security to an Institutional Accredited
Investor (other than pursuant to a registration statement that has been declared
effective under the Securities Act), such Institutional Accredited Investor
shall, prior to such sale or transfer, furnish to the Company and/or the Trustee
a signed letter containing representations and agreements relating to
restrictions on transfer substantially in the form set forth in Exhibit A to
this Indenture.

        Any Global Security may be endorsed with or have incorporated in the
text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian, the Depositary
or by the National Association of Securities Dealers, Inc. in order for the
Securities to be tradeable on The Portal Market or as may be required for the
Securities to be tradeable on any other market developed for trading of
securities pursuant to Rule 144A or Regulation S or required to comply with any
applicable law or any regulation thereunder or with the rules and regulations of
Euroclear, Cedel or any securities exchange or automated quotation system upon
which the Securities may be listed or traded or to conform with any usage with
respect thereto, or to indicate any special limitations or restrictions to which
any particular Securities are subject.

               (d) Every Security that bears or is required under this Section
3.4(d) to bear the legend set forth in this Section 3.4(d) (together with any
Common Stock issued upon conversion of the Securities and required to bear the
legend set forth in Section 3.4(e), collectively, the "Restricted Securities")
shall be subject to the restrictions on transfer set forth in this Section 3.4
(d) (including those set forth in the legend set forth below) unless such
restrictions on transfer shall be waived by written consent of the Company, and
the Holder of each such Restricted Security by such Holder's acceptance thereof,
agrees to be bound by all such restrictions on transfer. As used in Sections
3.4(d) and 3.4(e), the term "transfer" encompasses any sale, pledge, transfer or
other disposition whatsoever of any Restricted Security.

        Until the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision), any
certificate evidencing such Security (and all securities issued in exchange
therefor or substitution thereof, other than Common Stock, if any,



                                      -42-

issued upon conversion thereof, which shall bear the legend set forth in Section
3.4(e), if applicable) shall bear a legend in substantially the following form,

been declared effective under the Securities Act (and which continues to be
effective at the time of such transfer), or unless otherwise agreed by the
Company in writing, with written notice thereof to the Trustee:

        SUCCESSOR TRUSTEE, AS APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN
        REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER

        ACCREDITED INVESTOR OR A PURCHASER WHO IS NOT A U.S. PERSON, THE HOLDER
        MUST, PRIOR TO SUCH TRANSFER, FURNISH TO STATE STREET BANK AND TRUST
        COMPANY OF CALIFORNIA, N.A., AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS
        APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS
        IT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
        PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
        REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE
        REMOVED UPON THE EARLIER OF THE TRANSFER OF THE SECURITY EVIDENCED
        HEREBY PURSUANT TO CLAUSE 1(F) ABOVE OR UPON ANY TRANSFER OF THE
        SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR
        ANY SUCCESSOR PROVISION), AS USED HEREIN, THE TERMS "OFFSHORE
        TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN
        TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

        Any Security (or Successor Security issued in exchange or substitution
therefor) as to which such restrictions on transfer shall have expired in
accordance with their terms or as to the conditions for removal of the foregoing
legend set forth therein have been satisfied may, upon surrender of such
Security for exchange to the Note Registrar in accordance with the provisions of
this Section 3.4, be exchanged for a new Security or Securities of like tenor
and aggregate principal amount, which shall not bear the restrictive legend
required by this Section 3.4(d).

        Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in the second paragraph of Section 3.4(b) and in this
Section 3.4(d)), a Global Security may not be transferred as a whole or in part
except by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary.

        The Depositary shall be a clearing agency registered under the Exchange
Act. The Company initially appoints DTC to act as Depositary with respect to the
Global Securities. Initially, the Rule 144A Global Security and the Regulation S
Global Security shall be issued to the Depositary, registered in the name of
Cede & Co., as the nominee of the Depositary, and deposited with the Custodian
for Cede & Co.

        If at any time the Depositary for a Global Security notifies the Company
that it is unwilling or unable to continue as Depositary for such Global
Security, the Company may appoint a successor Depositary with respect to such
Global Security. If a successor Depositary is not appointed by the Company
within ninety (90) days after the Company receives such notice, the Company will
execute, and the Trustee, upon receipt of an Officers' Certificate for the
authentication and delivery of Securities, will authenticate and deliver,
Securities in certificated form, in aggregate principal amount equal to the
Principal Amount of such Global Security, in exchange for such Global Security.

        If a Security in certificated form is issued in exchange for any portion
of a Global Security after the close of business at the office or agency where
such exchange occurs on any Record Date and before the opening of business at
such office or agency on the next succeeding Interest Payment Date, interest
will not be payable on such Interest Payment Date in respect of such Security,
but will be payable on such Interest Payment Date, subject to the provisions of
Section 3.7, only to the Person to whom interest in respect of such portion of
such Global Security is payable in accordance with the provisions of this
Indenture.

        Securities in certificated form issued in exchange for all or a part of
a Global Security pursuant to this Section 3.4 shall be registered in such names
and in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. Upon execution and authentication, the Trustee shall deliver such
Securities in certificated form to the Persons in whose names such Securities in
certificated form are so registered.

        At such time as all interests in a Global Security have been redeemed,
repurchased, converted, canceled, exchanged for Securities in certificated form,
or transferred to a transferee who receives Securities in certificated form
thereof, such Global Security shall, upon receipt thereof, be canceled by the
Trustee in accordance with standing procedures and instructions existing between
the Depositary and the Custodian. At any time prior to such cancellation, if any
interest in a Global Security is exchanged for Securities in certificated form,
redeemed, converted, repurchased or canceled, exchanged for Securities in
certificated form or transferred to a transferee who receives Securities in
certificated form therefor or any Security in certificated form is exchanged or
transferred for part of a Global Security, the principal amount of such Security
shall, in accordance with the standing procedures and instructions existing
between the Depositary and the Custodian, be appropriately reduced or increased,
as the case may be, and an endorsement shall be made on such Global Security, by
the Trustee or the Custodian, at the direction of the Trustee, to reflect such
reduction or increase.

               (e) Until the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), any stock certificate representing Common Stock issued upon
conversion of such Security shall bear a legend in substantially the following
form, unless such Common Stock has been sold pursuant to a registration
statement that has been declared effective under the Securities Act (and which
continues to be effective at the time of such transfer) or such Common Stock has
been issued upon conversion of Securities that have been transferred pursuant to
a registration statement that has been declared effective under the Securities
Act, or unless otherwise agreed by the Company in writing with written notice
thereof to the Common Stock transfer agent:

        THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
        SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
        SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE
        UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS
        EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES
        THAT UNTIL THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF
        THE SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT
        (OR ANY SUCCESSOR PROVISION), (1) IT WILL NOT RESELL OR OTHERWISE
        TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO CYPRESS
        SEMICONDUCTOR CORPORATION OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE
        UNITED STATES TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE
        144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) INSIDE
        THE UNITED STATES TO AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED
        IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) THAT PRIOR
        TO SUCH TRANSFER FURNISHES TO BOSTON BANK, N.A., AS TRANSFER AGENT (OR A
        SUCCESSOR TRANSFER AGENT, AS APPLICABLE), A SIGNED LETTER CONTAINING
        CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON
        TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER
        CAN BE OBTAINED FROM SUCH TRANSFER AGENT OR A SUCCESSOR TRANSFER AGENT,
        AS APPLICABLE), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE
        904 UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM
        REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
        AVAILABLE), OR (F) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN
        DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE
        EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2) PRIOR TO SUCH TRANSFER
        (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 1(F) ABOVE), IT WILL FURNISH
        TO BOSTON BANK, N.A., AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT,
        AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION
        AS IT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
        PURSUANT TO AN EXEMPTION FROM, OR IN A



                                      -46-

<PAGE>   55



        TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
        SECURITIES ACT AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON
        STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO
        CLAUSE 1(F) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.
        THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE
        COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE 1(F) ABOVE OR UPON ANY
        TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY AFTER THE EXPIRATION OF
        THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY
        UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION).
        AS USED HEREIN, THE TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE
        MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

        Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms or as to which the conditions for
removal of the foregoing legend set forth therein have been satisfied may, upon
surrender of the certificates representing such shares of Common Stock for
exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of
shares of Common Stock, which shall not bear the restrictive legend required by
this Section 3.4(e).

               (f) Any Security or Common Stock issued upon the conversion or
exchange of a Security that, prior to the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), is purchased or owned by the Company or any Affiliate
thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction which results
in such Securities or Common Stock, as the case may be, no longer being
"restricted securities" (as defined under Rule 144).

SECTION 3.5.  Temporary Securities

        Pending the preparation of Securities in certificated form, the Company
may execute and the Trustee or an Authenticating Agent shall, upon the written
request of the Company, authenticate and deliver temporary Securities (printed
or lithographed). Temporary Securities shall be issuable in any authorized
denomination, and substantially in the form of the Securities in certificated
form, but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Company. Every such
temporary Security shall be executed by the Company and authenticated by the
Trustee or such Authenticating Agent upon the same conditions and in
substantially the same manner, and with the same effect, as the Securities in
certificated form. Without unreasonable delay the Company will execute and
deliver to the Trustee or such Authenticating Agent Securities in certificated
form (other than in the case of Global Securities) and thereupon any or all
temporary Securities (other than any such Global Security) may be surrendered in
exchange therefor, at each office or agency maintained by the Company and the
Trustee or such



                                      -47-

<PAGE>   56



Authenticating Agent shall authenticate and make available for delivery in
exchange for such temporary Securities an equal aggregate principal amount of
Securities in certificated form. Such exchange shall be made by the Company at
its own expense and without any charge therefor. Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits and
subject to the same limitations under this Indenture as Securities in
certificated form authenticated and delivered hereunder.

SECTION 3.6.  Mutilated, Destroyed, Lost or Stolen Securities

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

        If there be delivered to the Company and either to the Trustee or to a
Note Registrar:

                      (1) evidence to their satisfaction of the destruction,
loss or theft of any Security, and

                      (2) such security or indemnity as may be satisfactory to
the Company and the Trustee and such Note Registrar to save each of them and any
agent of either of them harmless, then, in the absence of actual notice to the
Company, the Trustee or the Note Registrar that such Security has been acquired
by a bona fide purchaser, the Company shall execute, and upon its request, the
Trustee or an Authenticating Agent shall authenticate and the Trustee or Note
Registrar shall deliver in lieu of any such destroyed, lost or stolen Security
or in exchange for the Security, a new Security 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, but
subject to any conversion rights, may, instead of issuing a new Security, pay
such Security.

        Upon the issuance of any new Security under this Section 3.6, 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 (other than any
stamp and other duties, if any, which may be imposed in connection therewith by
the United States of America or any political subdivision thereof or therein,
which shall be paid by the Company) and any other expenses (including the fees
and expenses of the Trustee, any Paying Agent and any Note Registrar) connected
therewith.

        Every new Security issued pursuant to this Section 3.6 in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and such new Security shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities duly issued
hereunder.



                                      -48-

<PAGE>   57



        The provisions of this Section 3.6 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies of any Holder with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 3.7.  Payment of Interest; Interest Rights Preserved.

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

               (1) The Company may elect to make payment of any Defaulted
        Interest to the Persons in whose names the Securities (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, 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 the Special Record
        Date for the payment of such Defaulted Interest, which shall be not more
        than 15 days and not less than 10 days prior to the date of the proposed
        payment and not less than 10 days after the receipt by the Trustee of
        the notice of the proposed payment. The Trustee shall promptly notify
        the Company of such Special Record Date and, in the name and at the
        expense of the Company, shall cause notice of the proposed payment of
        such Defaulted Interest and the Special Record Date therefor to be
        mailed, first-class postage prepaid, to each Holder of Securities at
        such Holder's address as it appears in the Note Register, not less than
        10 days prior to such Special Record Date. Notice of the proposed
        payment of such Defaulted Interest and the Special Record Date therefor
        having been so mailed, such Defaulted Interest shall be paid to the
        Persons in whose names the Securities (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 in any
        other lawful manner not inconsistent with the requirements of any
        securities exchange on which the



                                      -49-

<PAGE>   58



        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.

        In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name such Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted, interest whose Stated Maturity is after the
date of conversion of such Security shall not be payable.

SECTION 3.8.  Persons Deemed Owners.

        Prior to due presentment of a Security for registration of transfer, the
Company or 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, premium, if any, and
(subject to Section 3.7) 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.

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

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

SECTION 3.9.  Cancellation.

        All Securities surrendered for payment, redemption, repurchase,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the



                                      -50-

<PAGE>   59



Trustee. All Securities so delivered to the Trustee shall be canceled promptly
by the Trustee. No Securities shall be authenticated in lieu of or in exchange
for any Securities canceled as provided in this Section 3.9. The Trustee shall
destroy all canceled Securities in accordance with applicable law and its
customary practices in effect from time to time.

SECTION 3.10.  Computation of Interest.

        Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.


SECTION 3.11.  CUSIP Numbers.

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

                           SATISFACTION AND DISCHARGE

SECTION 4.1.  Satisfaction and Discharge of Indenture.

        This Indenture shall, upon Company Request, cease to be of further

10.3) have been delivered to the Trustee for cancellation; or

               (B) all such Securities not theretofore delivered to the Trustee
or the Paying Agent or its agent for cancellation (other than Securities
referred to in clauses (i) and (ii) of clause (1)(A) above)

                      (i) have become due and payable, or

                      (ii) will have become due and payable at their Stated

               notice of redemption by the Trustee in the name, and at the
               expense, of the Company,

        and the Company, in the case of clause (i), (ii) or (iii) above, has
        deposited or caused to be deposited with the Trustee as trust funds
        (immediately available to the Holders in the case of clause (i)) in
        trust for the purpose an amount sufficient to pay and discharge the
        entire indebtedness on such Securities not theretofore delivered to the
        Trustee for cancellation, for principal, premium, if any, and interest
        (including any applicable Additional Amounts and Liquidated Damages) 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 6.7, the obligations of

the Company to pay Additional Amounts and, if money shall have been deposited

survive. Funds held in trust pursuant to this Section are not subject to the
provisions of Article Thirteen.

SECTION 4.2.  Application of Trust Money.

        Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying

Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine to the Persons entitled thereto, of the principal, premium, if any,
and interest for whose payment such money has been deposited with the Trustee;
but such money need not be segregated from other funds except to the extent
required by law.

        All moneys deposited with the Trustee pursuant to Section 4.1 (and held
by it or any Paying Agent) for the payment of Securities subsequently converted
shall be returned to the Company upon a Company Request.

SECTION 5.1.  Events of Default.

        "Event of Default", wherever used herein, 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 Thirteen or be voluntary or involuntary
or be effected by operation of law or pursuant to any judgment, decree or order
of any court or any order, rule or regulation of any administrative or
governmental body):

               (1) default in the payment of the principal of or premium, if
        any, on any Security at its Maturity, whether or not such payment is
        prohibited by the subordination provisions of Article Thirteen; or

               (2) default in the payment of any interest (including any

SECTION 5.2.  Acceleration of Maturity; Rescission and Annulment.

        If an Event of Default (other than an Event of Default specified in
Section 5.1(4) or (5)) occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of the
Outstanding Securities may declare the principal of all the Securities to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal
and all accrued interest thereon shall become immediately due and payable. If an
Event of Default specified in Section 5.1(4) or (5) occurs, the principal of,
and accrued interest on, all the Securities shall ipso facto become immediately
due and payable without any declaration or other Act of the Holders or any act
on the part of the Trustee.

        At any time after such declaration of acceleration 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 Five provided, the Holders of a
majority in aggregate principal amount of the Outstanding Securities, by written
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if



                                      -54-

<PAGE>   63



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

                      (A) all overdue interest (including any Additional Amounts
               and Liquidated Damages) on all Securities,

                      (B) the principal of and premium, if any, on any
               Securities which have become due otherwise than by such
               declaration of acceleration and any interest thereon at the rate
               borne by the Securities,

                      (C) to the extent that payment of such interest is lawful,
               interest upon overdue interest at a rate of 6% per annum, 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, other than the nonpayment of the principal
of, and any interest on, Securities which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
5.13.

        No rescission or annulment referred to above shall affect any subsequent
default or impair any right consequent thereon.

SECTION 5.3.  Collection of Indebtedness and Suits for Enforcement by Trustee.

        The Company covenants that, if

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

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

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal and interest (including any Additional Amounts
and Liquidated Damages) and interest on any overdue principal and premium, if
any, and on any overdue interest (including any Additional Amounts and
Liquidated Damages), to the extent permitted by law, at a rate of 6% per annum,
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.



                                      -55-

<PAGE>   64



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

        If an Event of Default 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 by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

SECTION 5.4.  Trustee May File Proofs of Claim.

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

               (1) to file and prove a claim for the whole amount of principal,
        premium, if any, and interest owing and unpaid in respect of the
        Securities and take such other actions, including participating as a
        member, voting or otherwise, of any official committee of creditors
        appointed in such matter, and to file such other papers or documents, in
        each of the foregoing cases, as may be necessary or advisable in order
        to have the claims of the Trustee (including any claim for the
        reasonable compensation, expenses, disbursements and advances of the
        Trustee, its agents and counsel) and of the Holders of Securities
        allowed in such judicial proceeding, and

               (2) to collect and receive any moneys or other property payable
        or deliverable on any such claim 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 of Securities to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders of Securities to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and any other amounts due the Trustee under Section 6.7.



                                      -56-

<PAGE>   65



        Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
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 of a Security in any such proceeding;
provided, however, that the Trustee may, on behalf of such Holders, vote for the
election of a trustee in bankruptcy or similar official.

SECTION 5.5.  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 judgment
has been recovered.

SECTION 5.6.  Application of Money Collected.

        Any money collected by the Trustee pursuant to this Article Five 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, premium,
if any, 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 6.7;

               SECOND: To the payment of the amounts then due and unpaid for
        principal, premium, if any, or interest (including any Additional
        Amounts and Liquidated Damages) 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, premium, if any, and interest
        (including any Additional Amounts and Liquidated Damages), respectively;
        and

               THIRD:  Any remaining amounts shall be repaid to the Company.

SECTION 5.7.  Limitation on Suits.

        No Holder of any Security 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;



                                      -57-

<PAGE>   66



               (2) the Holders of not less than 25% in aggregate principal
        amount of the Outstanding Securities 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 aggregate principal amount of the Outstanding Securities;

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 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 such
Holders.

SECTION 5.8.  Unconditional Right of Holders to Receive Principal, Premium and
              Interest and to Convert.

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

SECTION 5.9.  Restoration of Rights and Remedies.

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

SECTION 5.10.  Rights and Remedies Cumulative.



                                      -58-

<PAGE>   67



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


SECTION 5.11.  Delay or Omission Not Waiver.

        No delay or omission of the Trustee or of any Holder of any Security 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 any
acquiescence therein. Every right and remedy given by this Article Five or by
law to the Trustee or to the Holders of Securities may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or (subject to the
limitations contained in this Indenture) by the Holders of Securities.

SECTION 5.12.  Control by Holders of Securities.

        Subject to Section 6.3(6), the Holders of a majority in aggregate
principal amount of the Outstanding Securities 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,
provided that

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

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

               (3) the Trustee need not take any action which might result in
        personal liability or be unjustly prejudicial to the Holders of
        Securities not consenting; and

               (4) such direction shall be presented by such Holders to the
        Trustee in a timely manner.

SECTION 5.13.  Waiver of Past Defaults.

        The Holders, either (a) through the written consent of not less than a
majority in aggregate principal amount of the Outstanding Securities, or (b) by
the adoption of a resolution, at a meeting of Holders of the Outstanding
Securities at which a quorum is present, by the Holders of the lesser



                                      -59-

<PAGE>   68



of (x) not less than a majority in aggregate principal amount of Outstanding
Securities and (y) at least 66-2/3% in aggregate principal amount of the
Outstanding Securities represented at such meeting, may on behalf of the Holders
of all the Securities waive any past default hereunder and its consequences,
except a default (1) in the payment of the principal of, premium, if any, or
interest on any Security, or (2) in respect of a covenant or provision hereof
which under Article Eight cannot be modified or amended without the consent of
the Holder of each Outstanding Security affected.

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

SECTION 5.14.  Undertaking for Costs.

        All parties to this Indenture agree, and each Holder of any Security by
his or her acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant.

SECTION 5.15.  Waiver of Stay, Extension and Usury Laws.

        The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension law or usury law or other
law that would prohibit or forgive the Company from paying all or any portion of
its obligations on the Securities as provided herein, 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 it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law and
covenants that it will not hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.


                                   ARTICLE SIX

                                   THE TRUSTEE

SECTION 6.1.  Certain Duties and Responsibilities.

        (a) Except during the continuance of an Event of Default,



                                      -60-

<PAGE>   69



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

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

        (b) In case an Event of Default has occurred and is continuing of which
a Responsible Officer of the Trustee has actual knowledge, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

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

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

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

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

        (d) 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.

        (e) 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 has
not been provided to it.

SECTION 6.2.  Notice of Defaults.

        Within 90 days after the occurrence of any default hereunder as to which
the Trustee has received written notice, the Trustee shall give to all Holders
of Securities, in the manner provided in Section 1.6, notice of such default,
unless such default shall have been cured or waived; provided, however, that,
except in the case of a default in the payment of the principal of, premium, if
any, or interest on any Security, the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust committee of directors or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interest of the
Holders; and provided, further, that in the case of any default of the character
specified in Section 5.1(3), no such notice to Holders of Securities 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.

SECTION 6.3.  Certain Rights of Trustee.

        Subject to the provisions of Section 6.1:

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

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

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

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

               (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 of Securities 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;



                                      -62-

               (6) the Trustee shall not be bound to make any investigation into

        instrument, opinion, report, notice, request, direction, consent, order,
        bond, debenture, note, coupon, other evidence of indebtedness or other
        paper or document, but the Trustee in its sole 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,

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

               (8) the permissive right of the Trustee to take or refrain from
        taking any actions enumerated in this Indenture shall not be construed
        as a duty and the Trustee shall not be answerable in such actions other
        than for its own negligence, bad faith or willful misconduct in
        exercising any such right; and

               (9) the Trustee shall not be liable for any action taken,
        suffered or omitted to be taken by it in good faith and reasonably
        believed by it to be authorized or within the discretion or rights or
        powers conferred upon it by the Indenture.

SECTION 6.4.  Not Responsible for Recitals or Issuance of Securities.

        The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) shall be taken as the statements of
the Company, and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture, of the Securities or of the
Common Stock issuable upon the conversion of the Securities. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

        The Trustee, any Authenticating Agent, any Paying Agent, any Conversion

agent.

        The Trustee may become and act as trustee under other indentures under
which other securities, or certificates of interest or participation in other
securities, of the Company are outstanding in the same manner as if it were not
Trustee hereunder.

SECTION 6.6.  Money Held in Trust.

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

SECTION 6.7.  Compensation and Reimbursement.

        The Company agrees

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

               (2) except as otherwise expressly provided herein, to reimburse
        the Trustee upon its request for all reasonable expenses, disbursements
        and advances incurred or made by the Trustee in accordance with any
        provision of this Indenture (including the reasonable compensation and
        the expenses and disbursements of its agents and counsel), except for
        any such expense, disbursement or advance as may be attributable to its
        negligence, bad faith or willful misconduct. The Trustee agrees to repay
        such expenses, disbursements and advances attributable to its
        negligence, bad faith or willful misconduct upon the entry of a final
        nonappealable determination that the Trustee engaged in negligence, bad
        faith or willful misconduct; and

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

        When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 5.1(4) or Section 5.1(5), the expenses
(including the reasonable charges of its counsel) and the compensation for the
services are intended to constitute expenses of the administration under any
applicable Federal or state bankruptcy, insolvency or other similar law.

        Any Paying Agent or Authenticating Agent appointed hereunder shall be
entitled to the benefits of Section 6.7(3) as if the indemnity set forth
therefor were specifically afforded to such Paying Agent or Authenticating
Agent.

        The provisions of this Section shall survive the termination of this
Indenture or the earlier resignation or removal of the Trustee, any Paying Agent
or any Authenticating Agent, as the case may be.

        The obligations of the Company under this Section to compensate the
Trustee, to pay or reimburse the Trustee for expenses, disbursements and
advances and to indemnify and hold harmless the Trustee shall constitute
additional indebtedness hereunder and shall survive the satisfaction and
discharge of this Indenture. As security for the performance of such obligations
of the Company, the Trustee shall have a claim prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
particular Securities.

SECTION 6.8.  Corporate Trustee Required; Eligibility.

        There shall at all times be a Trustee hereunder which shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such, having (or
if the Trustee is a member of a bank holding company, its bank holding company
has) a combined capital and surplus of at least U.S.$50,000,000, subject to
supervision or examination by Federal or state authority, in good standing. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of said supervising or examining authority, then for
the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article and a successor shall be appointed pursuant to Section 6.9.

SECTION 6.9.  Resignation and Removal; Appointment of Successor.

        (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.10.

        (b) The Trustee may resign at any time by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required
by Section 6.10 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.

        (c) The Trustee may be removed at any time by Act of the Holders of a
majority in aggregate principal amount of the Outstanding Securities, delivered
to the Trustee and the Company. If the instrument of acceptance by a successor
Trustee required by Section 6.10 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of removal, the removed Trustee
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

        (d) If at any time:

               (1) the Trustee shall cease to be eligible under Section 6.8 and
        shall fail to resign after written request therefor by the Company or by
        any Holder of a Security who has been a bona fide Holder of a Security
        for at least six months, or

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

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

        (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee and
shall comply with the applicable requirements of this Section and Section 6.10.
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in aggregate principal amount of the Outstanding
Securities delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in
accordance with the applicable requirements of Section 6.10, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders of Securities and accepted appointment in the manner required by this
Section and Section 6.10, any Holder of a Security who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

        (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to all Holders of
Securities in the manner provided in Section 1.6. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

SECTION 6.10.  Acceptance of Appointment by Successor.

        Every successor Trustee appointed hereunder 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



                                      -66-

<PAGE>   75



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. 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.

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

SECTION 6.11.  Merger, Conversion, Consolidation or Succession to Business.

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

SECTION 6.12.  Authenticating Agents.

        The Trustee may appoint an additional Authenticating Agent or Agents
with respect to the Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities issued upon exchange or substitution pursuant
to this Indenture.

        Securities authenticated by an Authenticating Agent 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, and every reference in
this Indenture to the authentication and delivery of Securities by the Trustee
or the Trustee's certificate of authentication 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, the District
of Columbia authorized under such laws to act as Authenticating Agent and
subject to supervision or examination by government or other fiscal authority.
If at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section 6.12, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this Section 6.12.

        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



                                      -67-

<PAGE>   76



consolidation to which such Authenticating Agent shall be a party, or any
corporation succeeding to all or substantially all of the corporate agency or
corporate trust business of an Authenticating Agent (including the duties under
this Indenture), shall continue to be an Authenticating Agent, provided such
corporation shall be otherwise eligible under this Section 6.12, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

        An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 6.12, the Trustee may appoint a successor
Authenticating Agent which shall be subject to acceptance by the Company. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 6.12.

        The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section 6.12 and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 6.7.

        If an Authenticating Agent is appointed with respect to the Securities
pursuant to this Section 6.12, the Securities may have endorsed thereon, in
addition to or in lieu of the Trustee's certification of authentication, an
alternative certificate of authentication in the following form:

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

provisions of Section 311 of the Trust Indenture Act regarding the collection of
claims against the Company (or any such other obligor).

by the chairman of the meeting to be not Outstanding. The chairman of the
meeting shall have no right to vote, except as a Holder of a Security or proxy.

        (d) Any meeting of Holders of Securities duly called pursuant to Section

meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings

presentations and surrenders may be made and notices and demands may be served
on the office or agency of the Trustee in the Borough of Manhattan, the City of
New York.

SECTION 10.3.  Money for Security Payments To Be Held in Trust.

        If the Company shall act as its own Paying Agent, it will, on or before
each due date of the principal of, premium, if any, or interest on any of the

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

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

        The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee

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 sums.

        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, premium, if any,
or interest on any Security and remaining unclaimed for the earlier of ten days
prior to the time such money would escheat to the state or two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

SECTION 10.4.  Additional Amounts.

        The Company will pay to the Holder of any Security Additional Amounts as
provided in the form of Security, as set forth in Section 2.2. Whenever in this
Indenture there is mentioned, in any context, the payment of the principal of,
premium, if any, or interest on, or in respect of, any Security, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
for in this Section to the extent that, in such context, Additional Amounts are,
were or would be payable in respect thereof pursuant to the provisions of this
Section and express mention of the payment of Additional Amounts (if applicable)
in any provisions hereof shall not be construed as excluding Additional Amounts
in those provisions hereof where such express mention is not made.

        At least 10 days prior to April 1, 1998, or an earlier Redemption Date
or Repurchase Date (and at least 10 days prior to each date of payment of
principal, premium, if any, or interest after April 1, 1998, or such earlier

office or agency of the Trustee in the Borough of Manhattan and the Paying Agent
in the Borough of Manhattan, The City of New York, if other than the Trustee or
an agent thereof, with an Officers' Certificate instructing the Trustee and such
Paying Agents whether or not such payment of principal of, premium, if any, or
interest on the Securities shall be made to the Holders of Securities subject to
withholding or deduction. If any withholding or deduction shall be required,
such Officers' Certificate shall specify the amount required to be withheld or
deducted with respect to such payments to such Holders of Securities and the
Company will pay to the Trustee or the applicable Paying Agent the Additional
Amounts, if any, required to be paid as set forth in the first sentence of this
Section 10.4. The Company covenants to indemnify the Trustee and any Paying
Agent for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence, bad faith or willful misconduct arising
out of or in connection with actions taken or omitted by any of them in reliance

conclusively rely on the fact that there is no such withholding.

SECTION 10.5.  Corporate Existence.

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

SECTION 10.6.  Statement by Officers as to Default.

        The Company will deliver to the Trustee within 120 days after the end of
each fiscal year of the Company an Officers' Certificate stating that in the
course of performance by the signers of their duties as such officers of the
Company they would normally obtain knowledge of whether any default exists in
the performance and observance of any of the terms, provisions and conditions of
this Indenture and whether the Company has kept, observed, performed and
fulfilled its obligations under this Indenture. Such Officers' Certificate shall
further state, as to each such officer signing such Certificate, to the best of
the knowledge of such officer, as of the date of such Officers' Certificate, (a)
whether any such default exists, (b) whether the Company (as applicable) during
the preceding fiscal year kept, observed, performed and fulfilled each and every
covenant and obligation of the Company under this Indenture and (c) whether
there was any default in the performance and observance of any of the terms,
provisions or conditions of this Indenture during such preceding fiscal year. If
the officer or officers signing the Officers' Certificate know of such a
default, whether then existing or occurring during such preceding fiscal year,
the Officers' Certificate shall describe such default and its status with
particularity. The Company shall also promptly notify the Trustee if the
Company's fiscal year is changed so that the end thereof is on any date other
than the then current fiscal year end date.

        The Company will deliver to the Trustee, forthwith upon becoming aware
of any default in the performance or observance of any covenant, agreement or
condition contained in this Indenture, or any Event of Default, an Officers'
Certificate specifying with particularity such default or Event of Default and
further stating what action the Company has taken, is taking or proposes to take
with respect thereto.

        Any notice required to be given under this Section 10.6 shall be
delivered to the Trustee at its Corporate Trust Office.

SECTION 10.7.  Delivery of Certain Information.

        At any time when the Company is not subject to Section 13 or 15(d) of
the Exchange Act, upon the request of a holder of a Restricted Security, the
Company will promptly furnish or cause to be furnished Rule 144A Information (as
defined below) to such holder of Restricted Securities, or to a prospective
purchaser of any such security designated by any such holder, as the case may
be, to the extent required to permit compliance by such holder with Rule 144A
under the Securities Act (or any successor provision thereto) in connection with
the resale of any such security; provided, however, that the Company shall not
be required to furnish such information in connection with any request made on
or after the date which is two years from the later of (i) the date such a
security (or any such predecessor security) was last acquired from the Company
or (ii) the date such a security (or any such predecessor security) was last
acquired from an "affiliate" of the Company within the meaning of Rule 144 under
the Securities Act (or any successor provision thereto). "Rule 144A Information"
shall be such information as is specified pursuant to Rule 144A(d)(4) under the
Securities Act (or any successor provision thereto).

                                   REDEMPTION OF SECURITIES

SECTION 11.1.  Right of Redemption.

        The Securities may be redeemed in accordance with the provisions of the
form of Security set forth in Section 2.2.

SECTION 11.2.  Applicability of Article.

        Redemption of Securities at the election of the Company or otherwise, as
permitted or required by any provision of the Securities or this Indenture,
shall be made in accordance with such provision and this Article Eleven.

SECTION 11.3.  Election to Redeem; Notice to Trustee.

        The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. In case of any redemption at the election of the Company
of any of the Securities, the Company shall, at least 45 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee in writing of such Redemption
Date. If the Securities are to be redeemed pursuant to an election of the
Company which is subject to a condition specified in the form of Security set
forth in Section 2.2, the Company shall furnish the Trustee with an Officers'
Certificate stating that the Company is entitled to effect such redemption and
setting forth a statement of facts showing that the conditions precedent to the
right of the Company so to redeem have occurred.

SECTION 11.4.  Selection by Trustee of Securities to Be Redeemed.

        If less than all the Securities are to be redeemed (other than pursuant
to the fourth paragraph on the reverse of the form of Security in Section 2.2),
the particular Securities to be redeemed shall be selected by the Trustee within
seven Business Days after it receives the notice described in 11.3, from the
Outstanding Securities not previously called for redemption, by such method as
the Trustee may deem fair and appropriate.

        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 may be treated by
the Trustee as Outstanding for the purpose of such selection.



                                      -80-

<PAGE>   89



        The Trustee shall promptly notify the Company and each Note Registrar in

        Notice of redemption shall be given in the manner provided in Section
1.6 to the Holders of Securities to be redeemed not less than 20 nor more than
60 days prior to the Redemption Date, and such notice shall be irrevocable.

        All notices of redemption shall state:

               (1) the Redemption Date,

        aggregate principal amount of Securities which will be outstanding after
        such partial redemption,

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

               (5) the Conversion Price then in effect, the date on which the
        right to convert the Securities to be redeemed will terminate and the
        places where such Securities, may be surrendered for conversion,

               (6) the place or places where such Securities are to be
        surrendered for payment of the Redemption Price and accrued interest, if
        any, and

               (7) in the case of a notice of redemption pursuant to the fourth
        paragraph on the reverse of the form of Security in Section 2.2, a form
        of written certification of each beneficial owner of a Security as to
        such beneficial owner's entitlement to Additional Amounts.

        In case of a partial redemption, the notice shall specify the serial and
CUSIP numbers (if any) and the portions thereof called for redemption and that
transfers and exchanges may occur on or prior to the Redemption Date.

        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 written request, by
the Trustee in the name of and at the expense of the Company. Notice of
redemption of Securities to be redeemed at the election of the Company received
by the Trustee shall be given by the Trustee to each Paying Agent in the name of
and at the expense of the Company.

SECTION 11.6.  Deposit of Redemption Price.

        By 10:00 a.m. (New York time) on any Redemption Date of the Securities,
the Company shall deposit with the Trustee or with the Paying Agent so directed
by the Trustee (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 10.3) an amount of money (which shall
be in immediately available funds on such Redemption Date) sufficient to pay the
Redemption Price of, and accrued interest on, all the Securities which are to be
redeemed on that date other than any Securities called for redemption on that
date which have been converted prior to the date of such deposit.

        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 any right of the Holder of
such Security, if a Security, or any Predecessor Security to receive interest as
provided in the last paragraph of Section 3.7) be paid to the Company on Company
Request as soon as administratively practicable after the Trustee receives such
Company Request or, if then held by the Company, shall be discharged from such
trust.

SECTION 11.7.  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, including accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price together with accrued and unpaid
interest to the Redemption Date; provided, however, that installments of
interest on Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such on the relevant Record Date according
to their terms and the provisions of Section 3.7.

        If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal amount of, premium, if any, and,
to the extent permitted by applicable law, accrued interest on such Security
shall, until paid, bear interest from the Redemption Date at a rate of 6% per
annum and such Security shall remain convertible into Common Stock until the
principal of such Security (or portion thereof, as the case may be) shall have
been paid or duly provided for.

SECTION 11.8.  Securities Redeemed in Part.

        Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company designated for that purpose pursuant to
Section 10.2 (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 Security without service
charge, a new Security or Securities, 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.

SECTION 11.9.  Conversion Arrangement on Call for Redemption.

        In connection with any redemption of Securities, the Company may arrange
for the purchase and conversion of any Securities by an agreement with one or
more investment bankers or other purchasers (the "Purchasers") to purchase such
securities by paying to the Trustee in trust for the Holders, on or before the
Redemption Date, an amount not less than the applicable Redemption Price,
together with interest accrued to the Redemption Date, of such Securities.
Notwithstanding anything to the contrary contained in this Article Eleven, the
obligation of the Company to pay the Redemption Price, together with interest
accrued to, but excluding, the Redemption Date, shall be deemed to be satisfied
and discharged to the extent such amount is so paid by such Purchasers. If such
an agreement is entered into (a copy of which shall be filed with the Trustee
prior to the close of business on the Business Day immediately prior to the
Redemption Date), any Securities called for redemption that are not duly
surrendered for conversion by the Holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, and consistent with
any agreement or agreements with such Purchasers, to be acquired by such
Purchasers from such Holders and (notwithstanding anything to the contrary
contained in Article Twelve) surrendered by such Purchasers for conversion, all
as of immediately prior to the close of business on the Redemption Date (and the
right to convert any such Securities shall be extended though such time),
subject to payment of the above amount as aforesaid. At the direction of the
Company, the Trustee shall hold and dispose of any such amount paid to it to the
Holders in the same manner as it would monies deposited with it by the Company
for the redemption of Securities. Without the Trustee's prior written consent,
no arrangement between the Company and such Purchasers for the purchase and
conversion of any Securities shall increase or otherwise affect any of the
powers, duties, responsibilities or obligations of the Trustee as set forth in
this Indenture, and the Company agrees to indemnify the Trustee from, and hold
it harmless against, any loss, liability or expense arising out of or in
connection with any such arrangement for the purchase and conversion of any
Securities between the Company and such Purchasers, including the costs and
expenses, including reasonable legal fees, incurred by the Trustee in the
defense of any claim or liability arising out of or in connection with the
exercise or performance of any of its powers, duties, responsibilities or
obligations under this Indenture.

                                 ARTICLE TWELVE

                            CONVERSION OF SECURITIES

SECTION 12.1.  Conversion Privilege and Conversion Price.

        Subject to and upon compliance with the provisions of this Article
Twelve, at the option of the Holder thereof, the Holder of any Security is
entitled at his option, at any time prior to the close of business on October 1,
2002, to convert such Security into fully paid and nonassessable shares
(calculated as to each conversion to the nearest 1/100th of a share) of Common
Stock of the Company at the Conversion Price, determined as hereinafter
provided, in effect at the time of conversion. Such conversion right shall be
subject, in the case of the conversion of any Global Security, to any applicable
book-entry procedures of the Depositary therefor and the following sentence. In
case a Security or portion thereof is called for redemption or is delivered for
repurchase, such conversion right in respect of the Security or portion so
called shall expire at the close of business on the Business Day prior to the
Redemption Date or the Repurchase Date (as defined in Article Fourteen), as the
case may be, unless the Company defaults in making the payment due upon
redemption or repurchase, as the case may be.

        The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") shall be initially U.S.$23.625
per share of Common Stock. The Conversion Price shall be adjusted in certain
instances as provided in this Article Twelve.

SECTION 12.2.  Exercise of Conversion Privilege.

        Beneficial owners of interests in a Global Security may exercise their
right of conversion by delivering to the Depositary the appropriate instruction
form for conversion pursuant to the Depositary's conversion program and, in the
case of conversions through Euroclear or Cedel, in accordance with Euroclear's
or Cedel's normal operating procedures. To convert a definitive Security into
shares of Common Stock, a Holder must (i) complete and manually sign the
conversion notice in the form set forth in Section 2.4 on the back of the
definitive Security (or complete and manually sign a facsimile thereof) and
deliver such notice to the Trustee at the Corporate Trust Office of the Trustee
or the office or agency of State Street Bank and Trust Company of California,
N.A., in New York, New York, (ii) surrender the definitive Security to the
Trustee at the Corporate Trust Office of the Trustee or the office or agency of
the State Street Bank and Trust Company of California, N.A., in New York, New
York, (iii) if required, furnish appropriate endorsements and transfer
documents, (iv) if required, pay all transfer or similar taxes, and (v) if
required, pay funds equal to interest payable on the next Interest Payment Date.
The date on which all of the foregoing requirements have been satisfied is the
date of surrender for conversion. The Trustee shall promptly deliver to the
Company and the Company's Common Stock transfer agent notification of such
notice of conversion at the address described in Section 1.5. Such notice of
conversion can be obtained from the Trustee at the Corporate Trust Office or the
office of any Conversion Agent. Each Security surrendered for conversion will be
converted into Common Stock in registered form. Each Security



                                      -84-

<PAGE>   93



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 (except Securities called for redemption
on a Redemption Date or to be repurchased on a Repurchase Date during, in each
case, such period) shall be accompanied by payment in New York Clearing House
funds or other 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 (or part thereof, as the case may be) being surrendered for conversion.
The interest so payable on such Interest Payment Date with respect to any
Security (or portion thereof, if applicable) which has been called for
redemption on a Redemption Date, or is repurchasable on a Repurchase Date,
occurring, in either case, during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date, which Security (or portion thereof, if
applicable) is surrendered for conversion during such period, shall be paid to
the Holder of such Security being converted in an amount equal to the interest
that would have been payable on such Security if such Security had been
converted as of the close of business on such Interest Payment Date. The
interest so payable on such Interest Payment Date in respect of any Security (or
portion thereof, as the case may be) which has not been called for redemption on
a Redemption Date, or is not eligible for repurchase on a Repurchase Date,
occurring, in either case, during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date, which Security (or
portion thereof, as the case may be) is surrendered for conversion during such
period, shall be paid to the Holder of such Security as of such Regular Record
Date. Except as provided in this paragraph and subject to the last paragraph of
Section 3.7, no cash payment or adjustment shall be made upon any conversion on
account of, if the date of conversion is not an Interest Payment Date, any
interest accrued from the Interest Payment Date next preceding the conversion
date, in respect of any Security (or part thereof, as the case may be)
surrendered for conversion, or on account of any dividends on the shares of
Common Stock issued upon conversion. The Company's delivery to the Holder of the
number of shares of Common Stock (and cash in lieu of fractions thereof, as
provided in this Indenture) into which a Security is convertible will be deemed
to satisfy the Company's obligation to pay the principal amount of the Security.

        Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion,
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the shares of Common Stock issuable upon conversion shall be
treated for all purposes as the record holder or holders of such Common Stock at
such time. As promptly as practicable on or after the conversion date, the
Company shall issue and deliver to the Trustee, for delivery to the Holder, a
certificate or certificates for the number of full shares of Common Stock
issuable upon conversion, together with payment in lieu of any fraction of a
share, as provided in Section 12.3.

        All shares of Common Stock delivered upon such conversion of Securities
that are Restricted Securities shall, if required, bear restrictive legends set
forth in Section 3.4(e) and shall be subject to the restrictions on transfer
provided in such legends. Neither the Trustee nor any agent maintained for the
purpose of such conversion shall have any responsibility for the inclusion or
content of any



                                      -85-

<PAGE>   94



such restrictive legends on such shares of Common Stock; provided, however, that
the Trustee or Conversion Agent shall have provided, to the Company or to the
Note Registrar for such shares of Common Stock, prior to or concurrently with a
request to the Company to deliver such shares of Common Stock, written notice
that the Securities delivered for conversion are Restricted Securities.

        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 the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal to
the unconverted portion of the principal amount of such Security. A Security may
be converted in part, but only if the principal amount of such Security to be
converted is any integral multiple of U.S.$1,000 and the principal amount of
such security to remain Outstanding after such conversion is equal to U.S.$1,000
or any integral multiple thereof.

SECTION 12.3.  Fractions of Shares.

        No fractional shares of Common Stock shall be issued upon conversion of
any Securities. 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 thereof shall be computed on the basis of the aggregate
principal amount of the Securities (or specified portions thereof) so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Securities (or specified portions
thereof), the Company shall calculate and pay a cash adjustment in respect of
such fraction (calculated to the nearest 1/100th of a share) in an amount equal
to the same fraction of the Current Market Price per share of Common Stock
(calculated in accordance with Section 12.4(8) below) at the close of business
on the day of conversion.

SECTION 12.4.  Adjustment of Conversion Price.

        The Conversion Price shall be subject to adjustments from time to time
as follows:

        (1) In case the Company shall hereafter pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock, the Conversion Price in effect at the opening of business on the date
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction, the numerator of which 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 of which shall be the sum of such
number of shares and the total number of shares constituting such dividend or
other distribution, such reduction to become effective immediately after the
opening of business on the day following the date fixed for such determination.
If any dividend or distribution of the type described in this Section 12.4(1) is
declared but not so paid or made, the Conversion Price shall again be adjusted
to the Conversion Price which would then be in effect if such dividend or
distribution had not been declared.



                                      -86-

<PAGE>   95



        (2) In case the Company shall issue rights or warrants to all holders of
its outstanding Common Stock entitling them (for a period expiring within 45
days after the date fixed for determination of stockholders entitled to receive
such rights or warrants) to subscribe for or purchase Common Stock at a price
per share less than the Current Market Price (as defined in Section 12.4(8)(b))
on the date fixed for determination of stockholders entitled to receive such
rights or warrants, the Conversion Price shall be adjusted so that the same
shall equal the price determined by multiplying the Conversion Price in effect
immediately prior to the date fixed for determination of shareholders entitled
to receive such rights or warrants by a fraction, the numerator of which shall
be the number of shares of Common Stock outstanding at the close of business on
the date fixed for determination of stockholders entitled to receive such rights
and warrants plus the number of shares which the aggregate offering price of the
total number of shares so offered would purchase at such Current Market Price,
and the denominator of which shall be the number of shares of Common Stock
outstanding on the date fixed for determination of stockholders entitled to
receive such rights and warrants plus the total number of additional shares of
Common Stock offered for subscription or purchase. Such adjustment shall be
successively made whenever any such rights and warrants are issued, and shall
become effective immediately after the opening of business on the day following
the date fixed for determination of stockholders entitled to receive such rights
or warrants. To the extent that shares of Common Stock are not delivered after
the expiration of such rights or warrants, the Conversion Price shall be
readjusted to the Conversion Price which would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the
basis of delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights or warrants are not so issued, the
Conversion Price shall again be adjusted to be the Conversion Price which would
then be in effect if such date fixed for the determination of stockholders
entitled to receive such rights or warrants had not been fixed. In determining
whether any rights or warrants entitle the holders to subscribe for or purchase
Common Stock at less than such Current Market Price, and in determining the
aggregate offering price of such Common Stock, there shall be taken into account
any consideration received by the Company for such rights or warrants, the value
of such consideration, if other than cash, to be determined by the Board of
Directors.

        (3) In case outstanding Common Stock shall be subdivided into a greater
number of shares of Common Stock, the Conversion Price in effect at the opening
of business on the day following the day upon which such subdivision becomes
effective shall be proportionately reduced, and conversely, in case outstanding
shares of Common Stock shall be combined into a smaller number of shares of
Common Stock, the Conversion Price in effect at the opening of business on the
day following the day upon which such combination becomes effective shall be
proportionately increased.

        (4) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock shares of any class of capital stock of the
Company (other than any dividends or distributions to which Section 12.4(1)
applies) or evidences of its indebtedness or assets (including securities, but
excluding any rights or warrants referred to in Section 12.4(2), and excluding
any dividend or distribution (x) paid exclusively in cash or (y) referred to in
Section 12.4(1) (any of the foregoing hereinafter in this Section 12.4(4) called
the "Distribution Securities")), then, in each such case, the Conversion Price
shall be reduced so that the same shall be equal to the price determined



                                      -87-

<PAGE>   96



by multiplying the Conversion Price in effect on the Distribution Record Date
with respect to such distribution by a fraction the numerator of which shall be
the Current Market Price per share of Common Stock on such Distribution Record
Date less the fair market value (as determined by the Board of Directors whose
determination shall be conclusive, and described in a resolution of the Board of
Directors) on the Distribution Record Date of the portion of the Distribution
Securities so distributed applicable to one share of Common Stock and the
denominator of which shall be the Current Market Price per share of Common
Stock, such reduction to become effective immediately prior to the opening of
business on the day following such Distribution Record Date; provided, however,
that in the event the then fair market value (as so determined) of the portion
of the Distribution Securities so distributed applicable to one share of Common
Stock is equal to or greater than the Current Market Price per share of the
Common Stock on the Distribution Record Date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each Holder shall have the
right to receive upon conversion the amount of Distribution Securities such
Holder would have received had such Holder converted each Security on the
Distribution Record Date. In the event that such dividend or distribution is not
so paid or made, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such dividend or distribution
had not been declared. If the Company's Board of Directors determines the fair
market value of any distribution for purposes of this Section 12.4(4) by
reference to the actual or when issued trading market for any securities, it
must in doing so consider the prices in such market over the same period used in
computing the Current Market Price of the Common Stock.

        Rights or warrants distributed by the Company to all holders of Common
Stock entitling the holders thereof to subscribe for or purchase shares of the
Company's capital stock (either initially or under certain circumstances), which
rights or warrants, until the occurrence of a specified event or events
("Trigger Event"): (i) are deemed to be transferred with such shares of Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future
issuances of shares of Common Stock, shall be deemed not to have been
distributed for purposes of this Section 12.4 (and no adjustment to the
Conversion Price under this Section 12.4 will be required) until the occurrence
of the earliest Trigger Event, whereupon such rights and warrants shall be
deemed to have been distributed and an appropriate adjustment (if any is
required) to the Conversion Price shall be made under this Section 12.4(4). If
any such right or warrant, including any such existing rights or warrants
distributed prior to the date of this Indenture, are subject to events, upon the
occurrence of which such rights or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets or different
amounts of any of the foregoing, or both, then the date of the occurrence of any
and each such event shall be deemed to be the date of distribution and record
date with respect to new rights or warrants with such rights (and a termination
or expiration of the existing rights or warrants without exercise by any of the
holders thereof). In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the
Conversion Price under this Section 12.4 was made, (1) in the case of any such
rights or warrants which shall all have been redeemed or repurchased without
exercise by any holders thereof, the Conversion Price shall be readjusted upon
such final redemption or repurchase to give effect to such distribution or
Trigger Event, as the case



                                      -88-

<PAGE>   97



may be, as though it were a cash distribution, equal to the per share redemption
or repurchase price received by a holder or holders of shares of Common Stock
with respect to such rights or warrants (assuming such holder had retained such
rights or warrants), made to all holders of shares of Common Stock as of the
date of such redemption or repurchase, and (2) in the case of such rights or
warrants which shall have expired or been terminated without exercise by any
holders thereof, the Conversion Price shall be readjusted as if such rights and
warrants had not been issued.

        Notwithstanding the foregoing, in the event that the Company shall
distribute rights or warrants to subscribe for additional shares of the Common
Stock (other than rights or warrants described in Section 12.4(2)), pro rata to
holders of Common Stock, and in the case of the rights issued pursuant to the
Company's rights agreement in existence as of the date hereof, the Company may,
in lieu of making any adjustment pursuant to this Section 12.4(4), make proper
provision (in the case of the Company's rights agreement in existence as of the
date hereof, to the extent it does not make proper provision) so that each
holder of a Security who converts such Security (or any portion thereof) after
the Distribution Record Date for such distribution shall be entitled to receive
upon such conversion, in addition to the shares of Common Stock issuable upon
such conversion (the "Conversion Shares"), a number of rights or warrants to be
determined as follows: (i) if such conversion occurs on or prior to the date for
the distribution to the holders of such rights or warrants of separate
certificates evidencing such rights or warrants (the "Distribution Date"), the
same number of rights or warrants to which a holder of a number of shares of
Common Stock equal to the number of Conversion Shares is entitled at the time of
such conversion in accordance with the terms and provisions of and applicable to
such rights or warrants; and (ii) if such conversion occurs after the
Distribution Date, the same number of rights or warrants to which a holder of
the number of shares of Common Stock into which the principal amount of the
Security so converted was convertible immediately prior to the Distribution Date
would have been entitled on the Distribution Date in accordance with the terms
and provisions of, and applicable to such rights or warrants.

        For purposes of this Section 12.4(4) and Sections 12.4(1) and (2), any
dividend or distribution to which this Section 12.4(4) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock (or both), shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, assets or shares of
capital stock other than such shares of Common Stock or rights or warrants (and
any Conversion Price reduction required by this Section 12.4(4) with respect to
such dividend or distribution shall then be made) immediately followed by (2) a
dividend or distribution of such shares of Common Stock or such rights or
warrants (and any further Conversion Price reduction required by Sections
12.4(1) and (2) with respect to such dividend or distribution shall then be
made), except (A) the Distribution Record Date of such dividend or distribution
shall be substituted as "the date fixed for the determination of shareholders
entitled to receive such dividend or other distribution" and "the date fixed for
such determination" within the meaning of Sections 12.4(1) and (2) and (B) any
shares of Common Stock included in such dividend or distribution shall not be
deemed "outstanding at the close of business on the date fixed for such
determination" within the meaning of Section 12.4(1).



                                      -89-

<PAGE>   98



        (5) In case the Company shall, by dividend or otherwise, distribute to
all holders of its Common Stock cash (excluding (x) any quarterly cash dividend
on the Common Stock to the extent the aggregate cash dividend per share of
Common Stock in any quarterly period does not exceed the greater of (A) the
amount per share of Common Stock of the next preceding quarterly cash dividend
on the Common Stock to the extent that such preceding quarterly dividend did not
require any adjustment of the Conversion Price pursuant to this Section 12.4(5)
(as adjusted to reflect subdivisions or combinations of the Common Stock), and
(B) 3.75% of the arithmetic average of the Closing Prices (determined as set
forth in Section 12.4(8)) during the ten Trading Days immediately prior to the
date of declaration of such dividend, (y) any dividend or distribution in
connection with the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary and (z) any cash that is distributed as part of
a distribution requiring a Conversion Price adjustment pursuant to Section
12.4(4)), then, in such case, the Conversion Price shall be reduced so that the
same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the close of business on such Distribution Record
Date by a fraction of which the numerator shall be the Current Market Price of
the Common Stock on the Distribution Record Date less the amount of cash so
distributed (and not excluded as provided above) applicable to one share of
Common Stock and the denominator shall be such Current Market Price of the
Common Stock, such reduction to be effective immediately prior to the opening of
business on the day following the Distribution Record Date; provided, however,
that in the event the portion of the cash so distributed applicable to one share
of Common Stock is equal to or greater than the Current Market Price of the
Common Stock on the Distribution Record Date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each Holder shall have the
right to receive upon conversion the amount of cash such Holder would have
received had such Holder converted each Security on the Distribution Record
Date. In the event that such dividend or distribution is not so paid or made,
the Conversion Price shall again be adjusted to be the Conversion Price which
would then be in effect if such dividend or distribution had not been declared.
If any adjustment is required to be made as set forth in this Section 12.4(5) as
a result of a distribution that is a quarterly dividend, such adjustment shall
be based upon the amount by which such distribution exceeds the amount of the
quarterly cash dividend permitted to be excluded pursuant hereto. If an
adjustment is required to be made as set forth in this Section 12.4(5) above as
a result of a distribution that is not a quarterly dividend, such adjustment
shall be based upon the full amount of the distribution.

        (6) In case a tender or exchange offer made by the Company or any
subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to stockholders of consideration per share of
Common Stock having a fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) that as of the last time (the "Expiration Time") tenders or
exchanges may be made pursuant to such tender or exchange offer (as it may be
amended) that exceeds the Current Market Price of the Common Stock on the
Trading Day next succeeding the Expiration Time, the Conversion Price shall be
reduced so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the Expiration Time by a
fraction of which the numerator shall be the number of Common Stock outstanding
(including any tendered or exchanged shares) on the Expiration Time multiplied
by the



                                      -90-

<PAGE>   99



Current Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged 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") and (y) the
product of the number of Common Stock outstanding (less any Purchased Shares) on
the Expiration Time and the Current Market Price of the Common Stock on the
Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time. In the event that the Company is obligated to purchase shares
pursuant to any such tender or exchange offer, but the Company is permanently
prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such tender or exchange offer
had not been made.

        (7) In case of a tender or exchange offer made by a Person other than
the Company or any Subsidiary of the Company for an amount which increases the
offeror's ownership of Common Stock to more than 25% of the Common Stock
outstanding and shall involve the payment by such Person of consideration per
share of Common Stock having a fair market value (as determined by the Board of
Directors, whose determination shall be conclusive, and described in a
resolution of the Board) at the last time (the "Tender Expiration Time") tenders
or exchanges may be made pursuant to such tender or exchange offer (as it shall
have been amended) that exceeds the Current Market Price per share of the Common
Stock on the Trading Day next succeeding the Tender Expiration Time, and in
which, as of the Tender Expiration Time the Board of Directors is not
recommending rejection of the offer, the Conversion Price shall be reduced so
that the same shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the Tender Expiration Time by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding
(including any tendered or exchanged shares) on the Tender Expiration Time
multiplied by the Current Market Price of the Common Stock on the Trading Day
next succeeding the Tender Expiration Time and the denominator shall be the sum
of (x) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders based on the acceptance (up to any maximum
specified in the terms of the tender or exchange offer) of all shares validly
tendered or exchanged and not withdrawn as of the Tender Expiration Time (the
shares deemed so accepted, up to any such maximum, being referred to as the
"Accepted Purchased Shares") and (y) the product of the number of shares of
Common Stock outstanding (less any Accepted Purchased Shares) on the Tender
Expiration Time and the Current Market Price of the Common Stock on the Trading
Day next succeeding the Tender Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Tender Expiration Time. In the event that such Person is obligated to purchase
shares pursuant to any such tender or exchange offer, but such Person is
permanently prevented by applicable law from effecting any such purchases or all
such purchases are rescinded, the Conversion Price shall again be adjusted to be
the Conversion Price which would then be in effect if such tender or exchange
offer had not been made. Notwithstanding the foregoing, the adjustment described
in this Section 12.4(7) shall not be made if, as of the Tender Expiration Time,



                                      -91-

<PAGE>   100



the offering documents with respect to such offer disclose a plan or intention
to cause the Company to engage in any transaction described in Article Seven.

        (8) For purposes of this Section 12.4, the following terms shall have
the meaning indicated:

               (a) "Closing Price" with respect to any securities on any day
        shall mean the closing sale price regular way on such day or, in case no
        such sale takes place on such day, the average of the reported closing
        bid and asked prices, regular way, in each case on the New York Stock
        Exchange, or, if such security is not listed or admitted to trading on
        such Exchange, on the principal security exchange or quotation system in
        the United States on which such security is quoted or listed or admitted
        to trading, or, the average of the closing bid and asked prices of such
        security on the over-the-counter market on the day in question as
        reported by the Nasdaq National Market or a similar generally accepted
        reporting service, or if not so available, in such manner as furnished
        by any New York Stock Exchange member firm selected from time to time by
        the Board of Directors for that purpose, or a price determined in good
        faith by the Board of Directors or, to the extent permitted by
        applicable law, a duly authorized committee thereof, whose determination
        shall be conclusive.

               (b) "Current Market Price" shall mean the average of the daily
        Closing Prices per share of Common Stock for the ten consecutive Trading
        Days immediately prior to the date in question; provided, however, that
        (1) if the "ex" date (as hereinafter defined) for any event (other than
        the issuance or distribution or Fundamental Change requiring such
        computation) that requires an adjustment to the Conversion Price
        pursuant to Section 12.4(1), (2), (3), (4), (5), (6) or (7) occurs
        during such ten consecutive Trading Days, the Closing Price for each
        Trading Day prior to the "ex" date for such other event shall be
        adjusted by multiplying such Closing Price by the same fraction by which
        the Conversion Price is so required to be adjusted as a result of such
        other event, (2) if the "ex" date for any event (other than the
        issuance, distribution or Fundamental Change requiring such computation)
        that requires an adjustment to the Conversion Price pursuant to Section
        12.4(1), (2), (3), (4), (5), (6) or (7) occurs on or after the "ex" date
        for the issuance or distribution requiring such computation and prior to
        the day in question, the Closing Price for each Trading Day on and after
        the "ex" date for such other event shall be adjusted by multiplying such
        Closing Price by the reciprocal of the fraction by which the Conversion
        Price is so required to be adjusted as a result of such other event, and
        (3) if the "ex" date for the issuance, distribution or Fundamental
        Change requiring such computation is prior to the day in question, after
        taking into account any adjustment required pursuant to clause (1) or
        (2) of this proviso, the Closing Price for each Trading Day on or after
        such "ex" date shall be adjusted by adding thereto the amount of any
        cash and the fair market value (as determined by the Board of Directors
        in a manner consistent with any determination of such value for purposes
        of Section 12.4(4), (6) or (7) whose determination shall be conclusive
        and described in a resolution of the Board of Directors) of the
        evidences of indebtedness, shares of capital stock or assets being
        distributed applicable to one share of Common Stock as of the close of
        business on the day before such "ex" date. For purposes



                                      -92-

<PAGE>   101



        of any computation under Section 12.4(6) or (7), the Current Market
        Price of the Common Stock on any date shall be deemed to be the average
        of the daily Closing Prices per share of Common Stock for such day and
        the next two succeeding Trading Days; provided, however, that if the
        "ex" date for any event (other than the tender or exchange offer
        requiring such computation) that requires an adjustment to the
        Conversion Price pursuant to Section 12.4(1), (2), (3), (4), (5), (6) or
        (7) occurs on or after the Expiration Time or Tender Expiration Time, as
        the case may be, for the tender or exchange offer requiring such
        computation and prior to the day in question, the Closing Price for each
        Trading Day on and after the "ex" date for such other event shall be
        adjusted by multiplying such Closing Price by the reciprocal of the
        fraction by which the Conversion Price is so required to be adjusted as
        a result of such other event. For purposes of this paragraph, the term
        "ex" date, (1) when used with respect to any issuance or distribution,
        means the first date on which the Common Stock trades regular way on the
        relevant exchange or in the relevant market from which the Closing Price
        was obtained without the right to receive such issuance or distribution,
        (2) when used with respect to any subdivision or combination of shares
        of Common Stock, means the first date on which the Common Stock trades
        regular way on such exchange or in such market after the time at which
        such subdivision or combination becomes effective, and (3) when used
        with respect to any tender or exchange offer means the first date on
        which the Common Stock trades regular way on such exchange or in such
        market after the Expiration Time or Tender Expiration Time, as the case
        may be, of such offer.

               (c) "fair market value" shall mean the amount which a willing
        buyer would pay a willing seller in an arm's length transaction.

               (d) "Distribution Record Date" shall mean, with respect to any
        dividend, distribution or other transaction or event in which the
        holders of Common Stock have the right to receive any cash, securities
        or other property or in which the Common Stock (or other applicable
        security) is exchanged for or converted into any combination of cash,
        securities or other property, the date fixed for determination of
        stockholders entitled to receive such cash, securities or other property
        (whether such date is fixed by the Board of Directors or by statute,
        contract or otherwise).

               (e) "Trading Day" shall mean (x) if the applicable security is
        listed or admitted for trading on the New York Stock Exchange or another
        national security exchange, a day on which the New York Stock Exchange
        or another national security exchange is open for business or (y) if the
        applicable security is quoted on the Nasdaq National Market, a day on
        which trades may be made on thereon or (z) if the applicable security is
        not so listed, admitted for trading or quoted, any day other than a
        Saturday or Sunday or a day on which banking institutions in the State
        of New York are authorized or obligated by law or executive order to
        close.

        (9) No adjustment in the Conversion Price shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(9)) would require an increase or



                                      -93-

<PAGE>   102



decrease of at least one percent in such price; 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, at its option, make such reductions in the
Conversion Price as the Board deems advisable, in addition to those required by
paragraphs (1), (2), (3), (4), (5), (6) or (7) of this Section 12.4 in order to
avoid or diminish any income tax to any holders of Common Stock or rights to
purchase Common Stock resulting from any dividend or distribution on Common
Stock (or rights to acquire such shares) or from any event treated as such for
income tax purposes, resulting from any dividend or distribution of shares or
issuance of rights or warrants to purchase or subscribe for shares or from any
event treated as such for income tax purposes.

        To the extent permitted by applicable law, the Company from time to time
may reduce the Conversion Price by any amount for any period of time if the
period is (i) at least twenty (20) days, (ii) the reduction is irrevocable
during the period and (iii) the Board shall have made a determination that such
reduction would be in the best interests of the Company, which determination
shall be conclusive. Whenever the Conversion Price is reduced pursuant to the
preceding sentence, the Company shall give notice of the reduction to the
Holders of Securities in the manner provided in Section 1.6 at least fifteen
(15) days prior to the date the reduced Conversion Price takes effect, and such
notice shall state the reduced Conversion Price and the period during which it
will be in effect.

        (11) No adjustment of the Conversion Price will result in zero or a
negative number.

SECTION 12.5.  Notice of Adjustments of Conversion Price.

        Whenever the Conversion Price is adjusted as herein provided:

               (1) the Company shall compute the adjusted Conversion Price in
        accordance with Section 12.4 and shall prepare a certificate signed by
        the President, Treasurer, Chief Financial Officer or Vice President of
        Finance of the Company setting forth the adjusted Conversion Price and
        showing in reasonable detail the facts upon which such adjustment is
        based, and such certificate shall promptly be filed with the Trustee and
        with each Conversion Agent; and

               (2) a notice stating that the Conversion Price has been adjusted
        and setting forth the adjusted Conversion Price shall promptly be
        prepared and as soon as practicable thereafter, such notice shall be
        provided by the Company to all Holders in accordance with Section 1.6.

Neither the Trustee nor any Conversion Agent shall be under any duty or
responsibility with respect to any such certificate or the information and
calculations contained therein, except to exhibit the same to any Holder of
Securities desiring inspection thereof at its office during normal business
hours.



                                      -94-

<PAGE>   103



Unless and until the Trustee shall receive such certificate, it may assume
without inquiry that the Conversion Price has not been adjusted.

SECTION 12.6.  Notice of Certain Corporate Action.

        In case:

               (a) the Company shall declare a dividend (or any other
        distribution) on all or substantially all of its Common Stock payable
        (i) otherwise than exclusively in cash or (ii) exclusively in cash in an
        amount that would require any adjustment pursuant to Section 12.4; or

               (b) the Company shall authorize the granting to the holders of
        its Common Stock of rights, options or warrants to subscribe for or
        purchase any shares of capital stock of any class or of any other rights
        that would require any adjustment pursuant to Section 12.4; or

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

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

               (e) the Company or any Subsidiary of the Company shall commence a
        tender offer for all or a portion of the Company's outstanding Common
        Stock (or shall amend any such tender offer);

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 10.2, and shall
cause to be provided to all Holders in accordance with Section 1.6, at least 20
days (or 10 days in any case specified in clause (a) or (b) above) prior to the
applicable record, expiration or effective date hereinafter specified, a notice
stating (x) 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, (y) the date on which the right to make tenders under such tender
offer expires or (z) the date on which such reclassification, consolidation,
merger, share exchange, conveyance, transfer, sale, dissolution, liquidation or
winding up is expected to become effective, and the date as of which it is
expected that holders of shares 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,
conveyance, transfer, sale, lease, dissolution, liquidation or winding up. If at
the time the Trustee shall not be the Conversion Agent, a copy of such notice
and



                                      -95-

<PAGE>   104



any notice referred to in the following paragraph shall also forthwith be filed
by the Company with the Trustee.

        The preceding paragraph to the contrary notwithstanding, the Company
shall cause to be filed at each office or agency maintained for the purpose of
conversion of Securities pursuant to Section 10.2, and shall cause to be
provided to all Holders in accordance with Section 1.6, notice of any tender
offer by the Company or any subsidiary of the Company for all or any portion of
the Common Stock at or about the time that such notice of tender offer is
provided to the public generally (such notice to be sent to all Holders within
five days after receipt of such notice by the Trustee or Conversion Agent from
the Company).

SECTION 12.7.  Company to Provide Common Stock.

        The Company shall ensure that the Company has, free from preemptive
rights, out of its authorized but unissued Common Stock, the full number of
shares of Common Stock for the purpose of effecting the conversion of
Securities.

SECTION 12.8.  Taxes on Conversions.

        The Company will pay any and all taxes and duties that may be payable in
respect of the issue or delivery of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax or
duty which may be payable in respect of any transfer involved in the issue and
delivery of 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 duty, or has established to the satisfaction of the
Company that such tax or duty has been paid.

SECTION 12.9.  Company Covenant as to Common Stock.

        The Company covenants that all Common Stock which may be delivered upon
conversion of Securities, upon such delivery, will have been duly authorized and
validly issued and will be fully paid and nonassessable and, except as provided
in Section 12.8, the Company will pay all taxes, liens and charges with respect
to the issue thereof.

SECTION 12.10.  Cancellation of Converted Securities.

        All Securities delivered for conversion shall be delivered to the
Trustee or its agent to be canceled by or at the direction of the Trustee, which
shall dispose of the same as provided in Section 3.9.






                                      -96-

<PAGE>   105



SECTION 12.11.  Provision in Case of Consolidation, Merger, or Sale of Assets of
                the Company.

        In case of any consolidation of the Company with, or merger of the
Company into, any other Person, or any merger of another Person into the Company
(other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding Common Stock of the Company) or any sale
or transfer of all or substantially all of the assets of the Company, the
Company and the Person formed by such consolidation or resulting from such
merger or which acquires such assets shall execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each Security then
Outstanding shall have the right thereafter, during the period such Security
shall be convertible as specified in Section 12.1, to convert such Security only
into the kind and amount of securities, cash and other property receivable upon
such consolidation, merger, sale or transfer 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, sale or transfer,
assuming such holder of Common Stock of the Company (i) is not a Person with
which the Company consolidated or into which the Company merged or which merged
into the Company or to which such sale or transfer 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,
sale or transfer (provided that if the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, sale or transfer is
not the same for each share of Common Stock of the Company held immediately
prior to such consolidation, merger, sale or transfer 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
purposes of this Section 12.11 the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, sale or transfer by the
holders of each Non-electing Share shall be deemed to be the kind and amount so
receivable per share by a plurality of the Non-electing Shares). Such
supplemental indenture shall provide for adjustments which, for events
subsequent to the effective date of such supplemental indenture, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article. The above provisions of this Section 12.11 shall similarly apply to
successive consolidations, mergers, sales or transfers. Notice of the execution
of such a supplemental indenture shall be given by the Company to the Holder of
each Security as provided in Section 1.6 promptly upon such execution.

        Neither the Trustee, any Paying Agent nor any Conversion Agent 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 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.

<PAGE>   106



SECTION 12.12.  Responsibility of Trustee for Conversion Provisions.

        The Trustee and any Conversion Agent shall not at any time be under any
duty or responsibility to any Holder of Securities 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, or herein or in any supplemental indenture
provided to be employed, in making the same, or whether a supplemental indenture
need be entered into. Neither the Trustee nor any Conversion Agent shall be
accountable with respect to the validity or value (or the kind or amount) of any
Common Stock, or of any other securities or property or cash, which may at any
time be issued or delivered upon the conversion of any Security; and it or they
do not make any representation with respect thereto. Neither the Trustee,
subject to the provisions of Section 6.1, nor any Conversion Agent shall be
responsible for any failure of the Company to make or calculate any cash payment
or to issue, transfer or deliver any Common Stock or share certificates or other
securities or property or cash upon the surrender of any Security for the
purpose of conversion; and the Trustee and any Conversion Agent shall not be
responsible for any failure of the Company to comply with any of the covenants
of the Company contained in this Article.


                                ARTICLE THIRTEEN

                           SUBORDINATION OF SECURITIES

SECTION 13.1.  Agreement of Subordination.

        The Company covenants and agrees, and each Holder of Securities issued
hereunder by his acceptance thereof likewise covenants and agrees, that all
Securities shall be issued subject to the provisions of this Article Thirteen;
and each Person holding any Security, whether upon original issue or upon
transfer, assignment or exchange thereof, accepts and agrees to be bound by such
provisions.

        The payment of the principal of, premium, if any, and interest on all
Securities (including, but not limited to, the Redemption Price with respect to
the Securities called for redemption in accordance with Article Eleven, or the
Repurchase Price with respect to Securities submitted for repurchase in
accordance with Article Fourteen, as the case may be, as provided in this
Indenture and Additional Amounts, if any, and Liquidated Damages, if any) issued
hereunder shall, to the extent and in the manner hereinafter set forth, be
subordinated and subject in right of payment to the prior payment in full in
cash of all Senior Indebtedness of the Company, whether outstanding at the date
of this Indenture or thereafter incurred.

        No provision of this Article Thirteen shall prevent the occurrence of
any default or Event of Default hereunder.




                                      -98-

<PAGE>   107



SECTION 13.2.  Payments to Holders.

        No payment shall be made with respect to the principal of, or premium,
if any, or interest on the Securities by the Company (including, but not limited
to, the Redemption Price with respect to the Securities to be called for
redemption in accordance with Article Eleven or the Repurchase Price with
respect to Securities submitted for repurchase in accordance with Article
Fourteen, as the case may be, as provided in this Indenture and Additional
Amounts, if any, and Liquidated Damages, if any), except payments and
distributions made by the Trustee as permitted by the first or second paragraph
of Section 13.5, if:

               (i) a default in the payment of principal, premium, interest,
        rent or other obligations due on any Senior Indebtedness of the Company
        has occurred and is continuing (or, in the case of Senior Indebtedness
        of the Company 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 Indebtedness
        of the Company), 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 but including any
        default in the payment of principal, premium, interest, rent or other
        obligations on Designated Senior Indebtedness that would be a payment
        default but for the period of grace specified in such instrument or
        lease) on Designated Senior Indebtedness occurs and is continuing that
        then permits holders of such Designated Senior Indebtedness to
        accelerate its maturity and the Trustee receives a notice of the default
        (a "Payment Blockage Notice") from a Representative of Designated Senior
        Indebtedness or a holder of Designated Senior Indebtedness or the
        Company.

        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 (unless such default was
waived, cured or otherwise ceased to exist and thereafter subsequently
reoccurred) 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 upon the earlier of:

                      (1) in the case of a payment default, 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, the earlier of the date on which such default is cured or waived or
ceases to exist or 179 days after the date on which



                                      -99-

<PAGE>   108



the applicable Payment Blockage Notice is received if the maturity of such
Designated Senior Indebtedness has not been accelerated,

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

        Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, moratorium of
payments, insolvency, receivership or other proceedings, all amounts due or to
become due upon all Senior Indebtedness of the Company shall first be paid in
full in cash or other payment satisfactory to the holders of such Senior
Indebtedness of the Company, or payment thereof in accordance with its terms
provided for in cash or other payment satisfactory to the holders of such Senior
Indebtedness of the Company before any payment is made on account of the
principal of, premium, if any, or interest (including Additional Amounts, if
any, or Liquidated Damages, if any) on the Securities by the Company (except
payments by the Company made pursuant to Article Four from monies deposited with
the Trustee pursuant thereto prior to commencement of proceedings for such
dissolution, winding-up, liquidation or reorganization); and upon any such
dissolution or winding-up or liquidation or reorganization of the Company or
bankruptcy, insolvency, receivership or other proceeding, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the Holders or the Trustee
would be entitled, except for the provision of this Article Thirteen, shall
(except as aforesaid) be paid by the Company or by any receiver, trustee in
bankruptcy, moratorium of payments, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders or by the Trustee under
this Indenture if received by them or it, directly to the holders of Senior
Indebtedness of the Company (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness of the Company held by such holders,
or as otherwise required by law or a court order) or their Representative or
Representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness of the Company may have
been issued, as their respective interests may appear, to the extent necessary
to pay all Senior Indebtedness of the Company in full, in cash or other payment
satisfactory to the holders of such Senior Indebtedness of the Company, after
giving effect to any concurrent payment or distribution to or for the holders of
Senior Indebtedness of the Company, before any payment or distribution is made
to the Holders or to the Trustee.

        For purposes of this Article Thirteen, 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, the payment of which
is subordinated at least to the extent provided in this Article Thirteen with
respect to the Securities to the payment of all Senior Indebtedness of the
Company which may at the time be outstanding; provided that (i) the Senior
Indebtedness of the Company is assumed by the new



                                      -100-

corporation, if any, resulting from any reorganization or readjustment, and (ii)
the rights of the holders of Senior Indebtedness of the Company (other than
leases which are not assumed by the Company or the new corporation, as the case
may be) are not, without the consent of such holders, altered by such
reorganization or readjustment. The merger of the Company into another
corporation or the liquidation or dissolution of the Company following the
conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided for in
Article Seven shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 13.2 if such other corporation
shall, as a part of such merger, conveyance or transfer, comply with the
conditions stated in Article Seven.

        In the event of the acceleration of the Securities because of an Event
of Default, no payment or distribution shall be made to the Trustee or any
Holder of Securities in respect of the principal of, premium, if any, or
interest on the Securities by the Company (including, but not limited to, the
Redemption Price with respect to the Securities called for redemption in
accordance with Article Eleven or the Repurchase Price with respect to
Securities submitted for repurchase in accordance with Article Fourteen, as the
case may be, as provided in this Indenture and Additional Amounts, if any, and
Liquidated Damages, if any), except payments and distributions made by the
Trustee as permitted by the first or second paragraph of Section 13.5, until all
Senior Indebtedness of the Company has been paid in full in cash or other
payment satisfactory to the holders of Senior Indebtedness of the Company or
such acceleration is rescinded in accordance with the terms of this Indenture.
If payment of the Securities is accelerated because of an Event of Default, the
Company shall promptly notify holders of Senior Indebtedness of the Company of
the acceleration.

        In the event that, notwithstanding the foregoing provisions, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing, shall be received by the Trustee or the
Holders of the Securities before all Senior Indebtedness of the Company is paid
in full in cash or other payment satisfactory to the holders of such Senior
Indebtedness of the Company, or provision is made for such payment thereof in
accordance with its terms in cash or other payment satisfactory to the holders
of such Senior Indebtedness of the Company, such payment or distribution shall
be held in trust for the benefit of and shall be paid over or delivered to the
holders of Senior Indebtedness of the Company or their Representative or
Representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness of the Company may have
been issued, as their respective interests may appear, as calculated by the
Company, for application to the payment of all Senior Indebtedness of the
Company remaining unpaid to the extent necessary to pay all Senior Indebtedness
of the Company in full in cash or other payment satisfactory to the holders of
such Senior Indebtedness of the Company, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of such
Senior Indebtedness of the Company.

        Nothing in this Article Thirteen shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 6.7. This Section 13.2 shall be
subject to the further provisions of Section 13.5.

SECTION 13.3.  Subrogation of Securities.

        Subject to the payment in full in cash of all Senior Indebtedness of the
Company, the Holders of the Securities shall be subrogated to the extent of the
payments or distributions made to the holders of such Senior Indebtedness of the
Company pursuant to the provisions of this Article Thirteen (equally and ratably
with the holders of all indebtedness of the Company which by its express terms
is subordinated to other indebtedness of the Company to substantially the same
extent as the Securities are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of Senior Indebtedness of the Company
to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Indebtedness of the Company until the
principal, premium, if any, and interest on the Securities shall be paid in
full; and, for the purposes of such subrogation, no payments or distributions to
the holders of the Senior Indebtedness of the Company 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 Thirteen, and no payment over
pursuant to the provisions of this Article Thirteen, to or for the benefit of
the holders of Senior Indebtedness of the Company by Holders of the Securities
or the Trustee, shall, as between the Company, its creditors other than holders
of Senior Indebtedness of the Company, and the Holders of the Securities, be
deemed to be a payment by the Company to or on account of the Senior
Indebtedness of the Company. It is understood that the provisions of this
Article Thirteen are and are intended solely for the purposes of defining the
relative rights of the Holders of the Securities, on the one hand, and the
holders of the Senior Indebtedness of the Company, on the other hand.

        Nothing contained in this Article Thirteen or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as among the
Company, its creditors other than the holders of Senior Indebtedness of the
Company, 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 premium, if any) and interest on the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders of the Securities
and creditors of the Company other than the holders of the Senior Indebtedness
of the Company, nor shall anything herein or therein 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 Thirteen of the holders of Senior Indebtedness of the Company
in respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

        Upon any payment or distribution of assets of the Company referred to in
this Article Thirteen, the Trustee, subject to the provisions of Section 6.1,
and the Holders of the Securities shall be entitled to rely upon any order or
decree made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of the Securities, for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior
Indebtedness of the Company and other Indebtedness of the



                                      -102-

<PAGE>   111



Company, the amount thereof or payable thereon and all other facts pertinent
thereto or to this Article Thirteen.

SECTION 13.4.  Authorization to Effect Subordination.

        Each Holder of a Security by the Holder's acceptance thereof authorizes
and directs the Trustee on the Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article Thirteen and appoints the Trustee to act as the Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding
referred to in Section 5.4 hereof at least 30 days before the expiration of the
time to file such claim, the holders of any Senior Indebtedness of the Company
or their Representatives are hereby authorized to file an appropriate claim for
and on behalf of the Holders of the Securities.

SECTION 13.5.  Notice to Trustee.

        The Company shall give prompt written notice in the form of an Officers'
Certificate to a Responsible Officer of the Trustee and to any Paying Agent of
any fact known to the Company which would prohibit the making of any payment of
monies deposited by the Company to or by the Trustee or any Paying Agent in
respect of the Securities pursuant to the provisions of this Article Thirteen.
Notwithstanding the provisions of this Article Thirteen 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 of monies
deposited by the Company to or by the Trustee in respect of the Securities
pursuant to the provisions of this Article Thirteen, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof at
the Corporate Trust Office from the Company (in the form of an Officers'
Certificate) or a Representative of Senior Indebtedness or of a holder or
holders of Senior Indebtedness of the Company or from any trustee thereof; and
before the receipt of any such written notice, the Trustee shall be entitled in
all respects to assume that no such facts exist; provided that if on a date not
fewer than two Business Days prior to the date upon which by the terms hereof
any such monies may become payable for any purpose (including, without
limitation, the payment of the principal of, or premium, if any, or interest on
any Security) the Trustee shall not have received, with respect to such monies,
the notice provided for in this Section 13.5, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies deposited by the Company and to apply the same to the
purpose for which they were received, and shall not be affected by any notice to
the contrary which may be received by it on or after such prior date.

        Notwithstanding anything in this Article Thirteen to the contrary,
nothing shall prevent any payment by the Trustee to the Holders of monies
deposited with it pursuant to Section 4.1, and any such payment shall not be
subject to the provisions of Section 13.1 or 13.2.

        The Trustee shall be entitled to rely on the delivery to it of a written
notice by a Representative or a Person representing himself to be a holder of
Senior Indebtedness of the



                                      -103-

<PAGE>   112



Company (or a trustee on behalf of such holder) to establish that such notice
has been given by a Representative or a holder of Senior Indebtedness of the
Company or a trustee on behalf of any such holder or holders. In the event that
the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness of the
Company to participate in any payment or distribution pursuant to this Article
Thirteen, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
of the Company held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to
the rights of such Person under this Article Thirteen, and if such evidence is
not furnished the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

SECTION 13.6.  Trustee's Relation to Senior Indebtedness of the Company.

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

        With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article Thirteen, and no
implied covenants or obligations with respect to the holders of Senior
Indebtedness of the Company shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness of the Company and the Trustee shall not be
liable to any holder of Senior Indebtedness of the Company if it shall pay over
or deliver to Holders of Securities, the Company or any other Person money or
assets to which any holder of Senior Indebtedness of the Company shall be
entitled by virtue of this Article Thirteen or otherwise.

SECTION 13.7.  No Impairment of Subordination.

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

SECTION 13.8.  Article Applicable to Paying Agents.

        If 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 (unless the context otherwise requires) be construed
as extending to and including such Paying Agent within its



                                      -104-

<PAGE>   113



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 the first paragraph of Section 13.5 shall not apply to the Company or any
Affiliate of the Company if it or such Affiliate acts as Paying Agent.

SECTION 13.9.  Senior Indebtedness of the Company Entitled to Rely.

        The holders of Senior Indebtedness of the Company (including, without
limitation, Designated Senior Indebtedness) shall have the right to rely upon
this Article Thirteen, and no amendment or modification of the provisions
contained herein shall diminish the rights of such holders unless such holders
shall have agreed in writing thereto.

SECTION 13.10.  Certain Conversions Deemed Payment.

        For the purposes of this Article Thirteen only, (1) the issuance and
delivery of junior securities upon conversion of Securities in accordance with
Article Twelve shall not be deemed to constitute a payment or distribution on
account of the principal of (or premium, if any) or interest on Securities or on
account of the purchase or other acquisition of Securities, and (2) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 12.2), property or securities (other than junior securities)
upon conversion of a Security shall be deemed to constitute payment on account
of the principal of such Security. For the purposes of this Section 13.10, the
term "junior securities" means (a) shares of any stock of any class of the
Company (including, without limitation, the Common Stock of the Company), or (b)
securities of the Company which are subordinated in right of payment to all
Senior Indebtedness of the Company which may be outstanding at the time of
issuance or delivery of such securities to substantially the same extent as, or
to a greater extent than, the Securities are so subordinated as provided in this
Article. Nothing contained in this Article Thirteen 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 Indebtedness of the Company
and the Holders, the right, which is absolute and unconditional, of the Holder
of any Security to convert such Security in accordance with Article Twelve.


                                ARTICLE FOURTEEN

                     REPURCHASE OF SECURITIES AT THE OPTION
                     OF THE HOLDER UPON A FUNDAMENTAL CHANGE

SECTION 14.1.  Right to Require Repurchase.

        In the event that a Fundamental Change (as hereinafter defined) shall
occur, then each Holder shall have the right, at the Holder's option, to require
the Company to repurchase, and upon the exercise of such right the Company shall
repurchase, all of such Holder's Securities, or any portion of the principal
amount thereof that is equal to U.S.$1,000 or any integral multiple thereof
(provided that no single Security may be repurchased in part unless the portion
of the principal amount of such



                                      -105-

<PAGE>   114



Security to be Outstanding after such repurchase is equal to U.S.$1,000 or
integral multiples of U.S.$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 14.2) at the following prices (expressed as percentages of
the principal amount thereof) (the "Repurchase Price") in the event of a
Fundamental Change occurring during the 12-month period beginning October 1
(plus interest accrued to, but excluding, the Repurchase Date):

and 100% at October 1, 2002; provided that if the Applicable Price with respect
to the Fundamental Change is less than the Reference Market Price, the Company
shall repurchase such Securities at a price equal to the foregoing Repurchase
Price multiplied by the fraction obtained by dividing the Applicable Price by
the Reference Market Price; and provided, further, that installments of interest
on Securities whose Stated Maturity is on or prior to the Repurchase Date shall
be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such on the Regular Record Date according to their
terms and the provisions of Section 3.7. Such right to require the repurchase of
the Securities shall not continue after a discharge of the Company from its
obligations with respect to the Securities in accordance with Article Four,
unless a Fundamental Change shall have occurred prior to such discharge.
Whenever in this Indenture (including Sections 2.2, 3.1, 5.1(1) and 5.8) 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 Indenture shall not be construed as excluding the
Repurchase Price in those provisions of this Indenture when such express mention
is not made.

SECTION 14.2.  Notices; Method of Exercising Repurchase Right, Etc.

               (a) Unless the Company shall have theretofore called for
redemption all of the Outstanding Securities, on or before the 30th day after
the occurrence of a Fundamental Change, the Company or, at the request and
expense of the Company, the Trustee, shall give to all Holders of Securities, in
the manner provided in Section 1.6, notice (the "Company Notice") of the
occurrence of the Fundamental Change 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:

                      (1) the Repurchase Date,



                                      -106-

<PAGE>   115



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

                      (3) the Repurchase Price,

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

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

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

        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 Securities.

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

               (b) To exercise a repurchase right, a Holder shall deliver to the
Trustee or any Paying Agent 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
Securities to be repurchased (and, if any Security is to be 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 exercise the repurchase right is being made thereby, and (ii) the
Securities 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 Securities 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.

               (c) 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 or the Paying Agent the Repurchase Price in cash, as provided above,
for payment to the Holder on the Repurchase Date together with accrued and
unpaid interest to the Repurchase Date payable with respect to the Securities as
to which their purchase right has been exercised; provided, however, that
installments of interest that mature on or prior to the Repurchase Date shall be
payable in cash, in the case of Securities, to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Regular Record Date.

<PAGE>   116



               (d) If any Security (or portion thereof) surrendered for
repurchase shall not be so paid on the Repurchase Date, the principal amount of
such Security (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 6% per annum, and each Security shall remain convertible into Common
Stock until the principal of such Security (or portion thereof, as the case may
be) shall have been paid or duly provided for.

               (e) Any Security 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
Security without service charge, a new Security or Securities, 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 Security so surrendered.

               (f) All securities delivered for repurchase shall be delivered to
the Trustee, the Paying Agent or any other agents (as shall be set forth in the
Company Notice) to be canceled by or at the direction of the Trustee, which
shall dispose of the same as provided in Section 3.9.

SECTION 14.3.  Merger, Consolidation, etc.

        In the case of any merger, consolidation, sale or transfer of all or
substantially all of the assets of the Company to which Section 12.11 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 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 on an established
automated over-the-counter trading market in the United States and such shares
constitute at the 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 Company and the
Person resulting from such merger or consolidation 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 Indenture relating to
the right of Holders to cause the Company to repurchase the Securities following
a Fundamental Change, including without limitation the applicable provisions of
this Article Fourteen and the definitions of the Common Stock and Fundamental
Change, as appropriate, and such other related definitions set forth herein as
determined in good faith by the Company and the Company (which determination
shall be conclusive and binding), to make such provisions apply in the event of
a subsequent Fundamental Change to the common stock and the issuer thereof if
different from the Company and the Common Stock of the Company (in lieu of the
Company and Common Stock of the Company).

Gentlemen:

        We are delivering this letter in connection with an offering of 6%
Convertible Subordinated Notes due 2002 (the "Notes") which are convertible into
shares of Common Stock, $.01 par value (the "Common Stock"), of Cypress
Semiconductor Corporation (the "Company").

        We hereby confirm that:

                  1. we are an "accredited investor" within the meaning of Rule
        501(a)(1), (2) or (3) under the Securities Act of 1933 (the "Securities
        Act") or an entity in which all of the equity owners are accredited
        investors within the meaning of Rule 501(a)(1), (2) or (3) under the
        Securities Act:

                  2. (A) any purchase of Notes by us will be for our own account
        or for the account of one or more other institutional accredited
        investors or as fiduciary for the account of one or more trusts, each of
        which is an "accredited investor" within the meaning of Rule 501(a)(7)
        under the Securities Act (such trusts, together with accredited
        investors within the meaning of Rule 501(a)(1), (2) or (3) under the
        Securities Act, an "Institutional Accredited Investor") and for each of
        which we exercise sole investment discretion or (B) we are a "bank,"
        within the meaning of Section 3(a)(2) of the Securities Act, or a
        "savings and loan association" or other institution described in Section
        3(l)(5)(a) of the Securities Act that is acquiring Notes as fiduciary
        for the account of one or more institutions for which we exercise sole
        investment discretion;

                  3. in the event that we purchase any Notes, we will acquire
        Notes having a minimum principal amount of not less than $250,000 for
        our own account or for any separate account for which we are acting;

                  4.  we have such knowledge and experience in financial and
        business matters that we are capable of evaluating the merits and risks
        of purchasing the Notes; and

                  5. we are not acquiring Notes with a view to distribution
        thereof or with any present intention of offering or selling Notes or
        the Common Stock issuable upon conversion



                                       -1-

        thereof, except as permitted below; provided that the disposition of our
        property and property of any accounts for which we are acting as
        fiduciary shall remain at all times within our control.

        We understand that the Notes are being offered in a transaction not
involving any public offering within the United States within the meaning of the
Securities Act and that the Notes and the shares of Common Stock issuable upon
conversion thereof have not been registered under the Securities Act, and we
agree, on our own behalf and on behalf of each account for which we acquire any
Notes, that if in the future we decide to resell or otherwise transfer such
Notes or the Common Stock issuable upon conversion thereof, such Notes or Common
Stock may be resold or otherwise transferred only (i) to the Company or any
subsidiary thereof, or (ii) inside the United States to a person who is a
"qualified institutional buyer" (as defined in Rule 144A under the Securities
Act) in a transaction meeting the requirements of Rule 144A, or (iii) inside the
United States to an Institutional Accredited Investor that, prior to such
transfer, furnishes to the Trustee or transfer agent for such securities a
signed letter containing certain representations and agreements relating to the
restrictions on transfer of such securities (the form of which letter can be
obtained from such Trustee or transfer agent), or (iv) outside the United States
in a transaction meeting the requirements of Rule 904 under the Securities Act,
or (v) pursuant to the exemption from registration provided by Rule 144 under
the Securities Art (if applicable), or (vi) pursuant to a registration statement
which has been declared effective under the Securities Act (and which continues
to be effective at the time of such transfer), and in each case, in accordance
with any applicable securities laws of any State of the United States or any
other applicable jurisdiction and in accordance with the legends set forth on
the Notes or the Common Stock issuable upon conversion thereof, as the case may
be. We further agree to provide any person purchasing any of the Notes or the
Common Stock issuable upon conversion thereof other than pursuant to clause (vi)
above from us a notice advising such purchaser that resales of such securities
are restricted as stated herein. We understand that the Trustee for the Notes
and/or the transfer agent for the Common Stock will not be required to accept
for registration of transfer any Notes or any shares of Common Stock issued upon
conversion of the Notes except upon presentation of evidence satisfactory to the
Company that the foregoing restrictions on transfer have been complied with. We
further understand that any Notes and any certificates representing Common Stock
will be in the form of definitive physical certificates and that such
certificates will bear a legend reflecting the substance of this paragraph other
than certificates representing Common Stock transferred pursuant to clause (vi)
above.

        We acknowledge that the Company, others and you will rely upon our
confirmations, acknowledgments and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.

Issue Date, file with the Commission a Shelf Registration Statement relating to
the offer and sale of the Registrable Securities by the Holders from time to
time in accordance with the methods of distribution elected by such Holders and
set forth in such Shelf Registration Statement and, thereafter, shall use its
reasonable efforts to cause such Shelf Registration Statement to be declared
effective under the Securities Act as soon as practicable, and in any event
within 180 calendar days after the Issue Date.

               (b) The Company shall use its reasonable efforts:

                      (i) To keep the Shelf Registration Statement continuously
               effective in order to permit the Prospectus forming part thereof
               to be usable by Holders for a period of two years from the Issue
               Date or such shorter period that will terminate upon the earliest
               of the following: (A) when all the Securities covered by the
               Shelf Registration Statement have been sold pursuant to the Shelf
               Registration Statement, (B) when all shares of Common Stock
               issued upon conversion of any such Securities that had not been
               sold pursuant to the Shelf Registration Statement have been sold
               pursuant to the Shelf Registration Statement and (C) when there
               shall cease to be outstanding Registrable Securities (in any such
               case, such period being called the "Effectiveness Period"); and

                      (ii) After the effectiveness of the Shelf Registration
               Statement, promptly upon the request of any Holder, to take any
               action reasonably necessary to register the sale of any
               Registrable Securities of such Holder and to identify such Holder
               as a selling securityholder.

The Company shall be deemed not to have used its reasonable efforts to keep the
Shelf Registration Statement effective during the requisite period if the
Company voluntarily takes any action that would result in Holders of Registrable
Securities covered thereby not being able to offer and sell any such Registrable
Securities during that period, unless (i) such action is required by applicable
law, (ii) the continued effectiveness of the Shelf Registration Statement would
require the Company to disclose a material financing, acquisition or other
corporate transaction, and the Board of Directors shall have determined in good
faith that such disclosure is not in the best interests of the Company and the
holders of its outstanding Common Stock,



                                       -4-

<PAGE>   5



or (iii) the Board of Directors shall have determined in good faith that there
is a valid business purpose or reason for such suspension, and (x), in the case
of clause (i) above, the Company thereafter promptly complies with the
requirements of paragraph 3(i) below and (y) the Company complies with its
obligations, if any, to pay Liquidated Damages.

               (c) (1) If (i) on or prior to 90 days following the Issue Date a
Shelf Registration Statement has not been filed with the Commission or (ii) on
or prior to the 180th day following the Issue Date, such Shelf Registration
Statement is not declared effective (each, a "Registration Default"), additional
interest ("Liquidated Damages") will accrue on the Restricted Securities from
and including the date following such Registration Default until such time as
such Shelf Registration Statement is filed or such Shelf Registration Statement
is declared effective, as the case may be. Liquidated Damages will be paid
semi-annually in arrears, with the first semi-annual payment due on the first
Interest Payment Date under the Indenture following the date on which such
Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to
an additional one-quarter of one percent (0.25%) of the principal amount, to and
including the 90th day following such Registration Default and one-half of one
percent (0.50%) thereof from and after the 91st day following such Registration
Default. In the event that Shelf Registration Statement ceases to be effective
for more than 90 days or the Company suspends the use of the prospectus which is
a part thereof for more than 90 days, whether or not consecutive, during any
12-month period, then the interest rate borne by Restricted Securities will
increase by an additional one-half of one percent (0.50%) per annum from the
91st day of the applicable 12-month period such Shelf Registration Statement
ceases to be effective or the Company suspends the use of the prospectus which
is a part thereof, as the case may be, until the earlier of such time as (i) the
Shelf Registration Statement again becomes effective, (ii) the use of the
related prospectus ceases to be suspended or (iii) the Effectiveness Period
expires. Following the cure of all Registration Defaults relating to any
Restricted Securities, the accrual of Liquidated Damages with respect to such
Restricted Securities will cease (without in any way limiting the effect of any
subsequent Registration Default). In no event shall the Company be required to
pay Liquidated Damages in excess of the applicable maximum amount of one-half of
one percent (0.50%) set forth above, regardless of whether one or multiple
Registration Defaults exist.

                      (2) Liquidated Damages on the Restricted Securities shall
be paid by the Company to the holders of record of such Restricted Securities on
each Interest Payment Date (as defined in the Indenture) in the same manner as
for interest on such Restricted Securities as provided in the form of Securities
set forth in Section 2.2 of the Indenture.

                      (3) All of the Company's obligations set forth in this
Section 2(c) which are unsatisfied to any extent with respect to any Restricted
Security at the time such security ceases to be a Restricted Security shall
survive until such time as all such obligations with respect to such security
have been satisfied in full (notwithstanding the earlier termination of this
Agreement).



                                       -5-

<PAGE>   6



                      (4) Any payments due and payable pursuant to this Section
2(c) shall be subordinated to Senior Indebtedness (as defined in the Indenture)
to the extent and in the manner set forth in the Indenture.

                      (5) The rights of the recordholders of Restricted
Securities to Liquidated Damages as set forth in this Section 2(c) is not
intended to be exclusive of any other right or remedy, and shall be in addition
to every other right and remedy given hereunder or under the Indenture or now or
hereafter existing at law or in equity or otherwise.

        3. REGISTRATION PROCEDURES. In connection with any Shelf Registration
Statement, the following provisions shall apply:

               (a) The Company shall furnish to the Special Counsel and Holders
        (if requested), prior to the filing thereof with the Commission, a copy
        of any Shelf Registration Statement, and each amendment thereof and each
        amendment or supplement, if any, to the Prospectus included therein and
        shall use its reasonable efforts to reflect in each such document, when
        so filed with the Commission, such comments as the Special Counsel and
        Holders reasonably may propose.

               (b) The Company shall take such action as may be necessary so
        that (i) any Shelf Registration Statement and any amendment thereto and
        any Prospectus forming part thereof and any amendment or supplement
        thereto (and each report or other document incorporated therein by
        reference in each case) complies in all material respects with the
        Securities Act and the Exchange Act, (ii) any Shelf Registration
        Statement and any amendment thereto does not, when it becomes effective,
        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 and (iii) any Prospectus forming part
        of any Shelf Registration Statement, and any amendment or supplement to
        such Prospectus, does not include an untrue statement of a material fact
        or omit to state a material fact necessary in order to make the
        statements, in the light of the circumstances under which they were
        made, not misleading.

               (c) (1) The Company shall advise the Initial Purchasers and, in
        the case of clause (i), the Holders and, if requested by any Initial
        Purchaser or any such Holder, confirm such advice in writing:

                             (i) when a Shelf Registration Statement and any
                      amendment thereto has been filed with the Commission and
                      when the Shelf Registration Statement or any post
                      effective amendment thereto has become effective; and

                             (ii) of any request by the Commission for
                      amendments or supplements to the Shelf Registration
                      Statement or the Prospectus included therein or for
                      additional information.

<PAGE>   7



                      (2) The Company shall advise the Holders and, if requested
               by any such Holder, confirm such advice in writing of:

                             (i) the issuance by the Commission of any stop
                      order suspending effectiveness of the Shelf Registration
                      Statement or the initiation of any proceedings for that
                      purpose;

                             (ii) the receipt by the Company of any notification
                      with respect to the suspension of the qualification of the
                      securities included therein for sale in any jurisdiction
                      or the initiation of any proceeding for such purpose; and

                             (iii) the happening of any event that requires the
                      making of any changes in the Shelf Registration Statement
                      or the Prospectus so that, as of such date, the Shelf
                      Registration Statement and the Prospectus do not contain
                      an untrue statement of a material fact and do not omit to
                      state a material fact required to be stated therein or
                      necessary to make the statements therein (in the case of
                      the Prospectus, in light of the circumstances under which
                      they were made) not misleading (which advice shall be
                      accompanied by an instruction to suspend the use of the
                      Prospectus until the requisite changes have been made).

               (d) The Company shall use its reasonable efforts to prevent the
        issuance, and if issued to obtain the withdrawal, of any order
        suspending the effectiveness of any Shelf Registration Statement at the
        earliest possible time.

               (e) The Company shall furnish to the Special Counsel and each
        Holder (if requested) with respect to a Shelf Registration Statement,
        without charge, at least one copy of such Shelf Registration Statement
        and any post-effective amendment thereto, including financial statements
        and schedules, and, if the Holder so requests in writing, all reports,
        other documents and exhibits (including those incorporated by
        reference).

               (f) The Company shall, during the Effectiveness Period, deliver
        to each Holder with respect to a Shelf Registration Statement, without
        charge, as many copies of the Prospectus (including each preliminary
        Prospectus) included in such Shelf Registration Statement and any
        amendment or supplement thereto as such Holder may reasonably request,
        and the Company consents (except during the continuance of any event
        described in Section 3(c)(2)(iii)) to the use of the Prospectus or any
        amendment or supplement thereto by each of the Holders in connection
        with the offering and sale of the Registrable Securities covered by the
        Prospectus or any amendment or supplement thereto during the
        Effectiveness Period.

               (g) Prior to any offering of Registrable Securities pursuant to
        any Shelf Registration Statement, the Company shall register or qualify
        or cooperate with the



                                       -7-

<PAGE>   8



        Special Counsel and Holders in connection with the registration or
        qualification of such Registrable Securities for offer and sale under
        the securities or blue sky laws of such jurisdictions as any such
        Holders reasonably request in writing and do any and all other acts or
        things necessary or advisable to enable the offer and sale in such
        jurisdictions of the Registrable Securities covered by such Shelf
        Registration Statement; provided, however, that in no event shall the
        Company be obligated to (i) qualify as a foreign corporation or as a
        dealer in securities in any jurisdiction where it would not otherwise be
        required to so qualify but for this Section 3(g), (ii) file any general
        consent to service of process in any jurisdiction where it is not as of
        the date hereof then so subject or (iii) subject itself to taxation in
        any jurisdiction if it is not so subject.

               (h) Unless any Registrable Securities shall be in book-entry only
        form, the Company shall cooperate with the Holders to facilitate the
        timely preparation and delivery of certificates representing Registrable
        Securities to be sold pursuant to any Shelf Registration Statement free
        of any restrictive legends and in such permitted denominations and
        registered in such names as Holders may request in connection with the
        sale of Registrable Securities pursuant to such Shelf Registration
        Statement.

               (i) Upon the occurrence of any event contemplated by paragraph
        3(c)(2)(iii) above, the Company shall promptly prepare a post-effective
        amendment to any Shelf Registration Statement or an amendment or
        supplement to the related Prospectus or file any other required document
        so that, as thereafter delivered to purchasers of the Registrable
        Securities included therein, the Prospectus will not include an untrue
        statement of a material fact or omit to state any material fact
        necessary to make the statements therein, in the light of the
        circumstances under which they were made, not misleading. If the Company
        notifies the Holders of the occurrence of any event contemplated by
        paragraph 3(c)(2)(iii) above, the Holders shall suspend the use of the
        Prospectus until the requisite changes to the Prospectus have been made.

               (j) Not later than the effective date of any Shelf Registration
        Statement hereunder, the Company shall provide a CUSIP number for the
        Securities registered under such Shelf Registration Statement.

               (k) The Company shall use its reasonable efforts to comply with
        all applicable rules and regulations of the Commission and shall make
        generally available to their securityholders or otherwise provide in
        accordance with Section 11(a) of the Securities Act as soon as
        practicable after the effective date of the applicable Shelf
        Registration Statement an earnings statement satisfying the provisions
        of Section 11(a) of the Securities Act.

               (l) The Company shall cause the Indenture and the Securities to
        be qualified under the Trust Indenture Act in a timely manner; and in
        connection with such qualification, the Company shall cooperate with the
        Trustee under the Indenture and the Holders (as defined in the
        Indenture) to effect such changes to the Indenture as may



                                       -8-

<PAGE>   9



        be required for such Indenture to be so qualified in accordance with the
        terms of the Trust Indenture Act; and the Company shall execute and use
        all reasonable efforts to cause the Trustee to execute, all documents
        that may be required to effect such changes and all other forms and
        documents required to be filed with the Commission to enable such
        Indenture to be so qualified in a timely manner.

               (m) The Company may require each Holder with respect to a Shelf
        Registration Statement to furnish to the Company such information
        regarding the Holder and the distribution of Registrable Securities held
        by such Holder as may be required by applicable law or regulation for
        inclusion in such Shelf Registration Statement (including, without
        limitation, the information required by Item 507 of Regulation S-K of
        the Securities Act), and the Company may exclude from such registration
        the Registrable Securities of any Holder that fails to furnish such
        information within a reasonable time after receiving such request
        unless, and until such time as, such information is furnished by such
        Holder.

               (n) The Company shall enter into such customary agreements
        (including underwriting agreements in customary form) to take all other
        appropriate actions in order to expedite or facilitate the registration
        or the disposition of the Registrable Securities, and in connection
        therewith, if an underwriting agreement is entered into pursuant to an
        underwritten offering in accordance with the provisions of Section 6,
        cause the same to contain indemnification provisions and procedures
        substantially identical to those set forth in Section 5 (or such other
        provisions and procedures acceptable to the Managing Underwriters, if
        any) with respect to all parties to be indemnified pursuant to Section
        5.

               (o) The Company shall make reasonably available for inspection by
        one representative of the Holders designated in writing by the Holders
        of a majority of the Registrable Securities to be registered thereunder,
        any underwriter participating in any disposition pursuant to such Shelf
        Registration Statement, and any attorney, accountant or other agent
        retained by such representative or any such underwriter all relevant
        financial and other records, pertinent corporate documents and
        properties of the Company and its subsidiaries;

               (p) The Company shall cause the Company's officers, directors and
        employees to make reasonably available for inspection all relevant
        information reasonably requested by such representative or any such
        underwriter, attorney, accountant or agent in connection with any such
        Shelf Registration Statement, in each case, as is customary for similar
        due diligence examinations; provided, however, that any information that
        is designated in writing by the Company, in good faith, as confidential
        at the time of delivery of such information shall be kept confidential
        by such representative, any Holders or any such underwriter, attorney,
        accountant or agent, unless such disclosure is made in connection with a
        court proceeding or required by law,



                                       -9-

<PAGE>   10



        or such information becomes available to the public generally or through
        a third party without an accompanying obligation of confidentiality;

               (q) The Company will use its reasonable efforts to cause the
        Common Stock issuable upon conversion of the Securities to be admitted
        for quotation on the New York Stock Exchange or other stock exchange or
        trading system on which the Common Stock primarily trades on or prior to
        the effective date of any Shelf Registration Statement hereunder.

               (r) In the event that any broker-dealer registered under the
        Exchange Act shall underwrite any Registrable Securities or participate
        as a member of an underwriting syndicate or selling group or "assist in
        the distribution" (within the meaning of the Rules of Fair Practice and
        the By-Laws of the National Association of Securities Dealers, Inc.
        ("NASD")) thereof, whether as a Holder of such Registrable Securities or
        as an underwriter, a placement or sales agent or a broker or dealer in
        respect thereof, or otherwise, assist such broker-dealer in complying
        with the requirements of such Rules and By-Laws, including, without
        limitation, by (A) such Rules or By-Laws, including Schedule E thereto,
        shall so require, engaging a "qualified independent underwriter" (as
        defined in Schedule E) to participate in the preparation of the Shelf
        Registration Statement relating to such Registrable Securities and to
        exercise usual standards of due diligence in respect thereto, (B)
        indemnifying any such qualified independent underwriter to the extent of
        the indemnification of underwriters provided in Section 5 hereof and (C)
        providing such information to such broker-dealer as may be required in
        order for such broker-dealer to comply with the requirements of the
        Rules of Fair Practice of the NASD.

               (s) The Company shall use its reasonable efforts to take all
        other steps necessary to effect the registration, offering and sale of
        the Registrable Securities covered by the Shelf Registration Statement
        contemplated hereby.

               (t) Notwithstanding any provision of this Section 3 to the
        contrary, the Company shall not be required to amend or supplement the
        Shelf Registration Statement pursuant to the requirements of Sections
        3(b), 3(c), 3(i) or 3(s) hereof if (i) such amendment or supplement
        would require the Company to disclose a material financing, acquisition
        or corporate transaction and the Board of Directors shall have
        determined that such disclosure is not in the best interests of the
        Company and the holders of its outstanding Common Stock or (ii) the
        Board of Directors shall have determined in good faith that there is a
        valid business purpose or reason for suspending the use of the
        Prospectus included in such Shelf Registration Statement in accordance
        with Section 3(i) hereof instead of making such amendment or supplement,
        provided that in each such case the Company complies with its
        obligations, if any, to pay Liquidated Damages.



                                      -10-

<PAGE>   11



        4. REGISTRATION EXPENSES. Except as otherwise provided in Section 6, the
Company shall bear all fees and expenses incurred in connection with the
performance of its obligations under Sections 2 and 3 hereof and shall bear or
reimburse the Holders for the reasonable fees and disbursements of a Special
Counsel designated by the Company. For purposes of this Agreement, the Company
initially appoints Venture Law Group, as Special Counsel; provided that the
Holders of a majority of the Registrable Securities covered by the Shelf
Registration Statement have the right pursuant to this Agreement to substitute
another firm of counsel as Special Counsel under this Agreement.

        5. INDEMNIFICATION AND CONTRIBUTION. (a) In connection with any Shelf
Registration Statement, the Company shall indemnify and hold harmless each
Holder, the Initial Purchasers, each underwriter who participates in an offering
of Registrable Securities, each person, if any, who controls any of such parties
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act and each of their respective directors, officers, employees,
trustees and agents, as follows:

               (i) against any and all loss, liability, claim, damage and
        expense whatsoever, including any amounts paid in settlement of any
        investigation, litigation, proceeding or claim, joint or several, as
        incurred, arising out of any untrue statement or alleged untrue
        statement of a material fact contained in any Shelf Registration
        Statement (or any amendment thereto) covering Registrable Securities,
        including all documents incorporated therein by reference, or the
        omission or alleged omission therefrom of a material fact required to be
        stated therein or necessary to make the statements therein not
        misleading or arising out of any untrue statement or alleged untrue
        statement of a material fact contained in any Prospectus (or any
        amendment or supplement thereto) or the omission or alleged omission
        therefrom of a material fact necessary in order to make the statements
        therein, in the light of the circumstances under which they were made,
        not misleading; provided, that the Company shall not be liable under
        this clause (i) for any settlement of any action effected without its
        written consent, which consent shall not be unreasonably withheld; and

               (ii) against any and all expenses whatsoever, as incurred
        (including reasonable fees and disbursements of counsel chosen by the
        Holders, such Holder or any underwriter (except to the extent otherwise
        expressly provided in Section 5(c) hereof)), reasonably incurred in
        investigating, preparing or defending against any litigation, or any
        investigation or proceeding by any court or governmental agency or body,
        commenced or threatened, or any claim whatsoever based upon any such
        untrue statement or omission, or any such alleged untrue statement or
        omission, to the extent that any such expense is not paid under
        subparagraph (i) of this Section 5(a);

provided that this indemnity shall not apply to any loss, liability, claim,
damage or expense to the extent arising out of an untrue statement or omission
or alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Company by such Holder or any
underwriter in writing expressly for use in the Shelf



                                      -11-

<PAGE>   12



Registration Statement (or any amendment thereto) or any Prospectus (or any
amendment or supplement thereto). Any amounts advanced by the Company to an
indemnified party pursuant to this Section 5 as a result of such losses shall be
returned to the Company if it shall be finally determined by such a court in a
judgment not subject to appeal or final review that such indemnified party was
not entitled to indemnification by the Company.

        (b) Each Holder shall agree, severally and not jointly, to indemnify and
hold harmless the Company, each underwriter who participates in an offering of
Registrable Securities and the other Holders and each of their respective
directors, officers (including each officer of the Company who signed the Shelf
Registration Statement), employees, trustees and agents and each Person, if any,
who controls the Company, any underwriter or any other Holder within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 5(a)(i) and (ii) hereof, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Shelf Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company by such Holder expressly for use in the Shelf Registration Statement (or
any amendment thereto) or any Prospectus (or any amendment or supplement
thereto); provided, however, that, no such Holder shall be liable for any claims
hereunder in excess of the amount of net proceeds received by such Holder from
the sale of Registrable Securities pursuant to the Shelf Registration Statement.

        (c) Each indemnified party shall give prompt notice to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, enclosing a copy of all papers served on such indemnified
party, but failure to so notify an indemnifying party shall not relieve it of
any liability which it may have to the indemnified party otherwise than on
account of this indemnity agreement. An indemnifying party may participate at
its own expense in the defense of any such action. If an indemnifying party so
elects within a reasonable time after receipt of such notice, such indemnifying
party, jointly with any other indemnifying party, may assume the defense of such
action with counsel chosen by it and approved by the indemnified party or
parties defendant in such action, provided that if any such indemnified party
reasonably determines that there may be legal defenses available to such
indemnified party which are different from or in addition to those available to
such indemnifying party or that representation of such indemnifying party and
any indemnified party by the same counsel would present a conflict of interest,
then such indemnifying party or parties shall not be entitled to assume such
defense. If an indemnifying party is not entitled to assume the defense of such
action as a result of the proviso to the preceding sentence, counsel for such
indemnifying party shall be entitled to conduct the defense of such indemnifying
party and counsel for each indemnified party or parties shall be entitled to
conduct the defense of such indemnified party or parties. If an indemnifying
party assumes the defense of an action in accordance with and as permitted by
the provisions of this paragraph, such indemnifying party shall not be liable
for any fees and expenses of counsel for the indemnified parties incurred
thereafter in connection with such action. In no event shall the indemnifying
party or parties



                                      -12-

<PAGE>   13



be liable for the fees and expenses of more than one counsel (in addition to any
local counsel) separate from its own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.

        (d) In order to provide for just and equitable contribution in
circumstances in which the indemnity provision agreement provided for in this
Section 5 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company and the Holders
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by said indemnity agreement incurred by the
Company and the Holders, as incurred; provided that no Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person that was not
guilty of such fraudulent misrepresentation. As between the Company, on the one
hand, and the Holders, on the other hand, such parties shall contribute to such
aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by such indemnity agreement in such proportion as shall be
appropriate to reflect the relative fault of the Company, on the one hand, and
the Holders, on the other hand, with respect to the statements or omissions
which resulted in such loss, liability, claim, damage or expense, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative fault of the Company, on the one hand, and of the Holders, on the other
hand, 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 by or on behalf of the Holders, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Initial Purchasers agree, and the Holders shall agree, that it would not be
just and equitable if contribution pursuant to this Section 5 were to be
determined by pro rata allocation or by any other method of allocation that does
not take into account the relevant equitable considerations. For purposes of
this Section 5(d), each director, officer, employee, trustee, agent and Person,
if any, who controls a Holder within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act shall have the same rights to contribution
as such Holder, and each director, officer, employee, trustee and agent of the
Company, and each Person, if any, who controls the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act shall have
the same rights to contribution as the Company. No party shall be liable for
contribution with respect to any action, suit, proceeding or claim settled
without its written consent.

        (e) The Company may require, as a condition to including any Registrable
Securities in any Registration Statement filed and to entering into any
underwriting agreement with respect thereto, that the Company shall have
received an undertaking reasonably satisfactory to it from the Holder of such

        6. UNDERWRITTEN OFFERING. The Holders who desire to do so may sell
Registrable Securities in an underwritten offering. In any such underwritten
offering, the investment banker or bankers and manager or managers that will
administer the offering will be selected by, and the underwriting arrangements
with respect thereto will be approved by the Holders of a majority of the
Registrable Securities to be included in such offering; provided, however, that
(i) such investment bankers and managers and underwriting arrangements must be
reasonably satisfactory to the Company and (ii) the Company shall not be
obligated to arrange for more than one underwritten offering during the
Effectiveness Period. No Holder may participate in any underwritten offering
contemplated hereby unless such Holder (a) agrees to sell such Holder's
Registrable Securities in accordance with any approved underwriting
arrangements, (b) completes and executes all reasonable questionnaires, powers
of attorney, indemnities, underwriting agreements, lock-up letters and other
documents required under the terms of such approved underwriting arrangements
and (c) at least 20% of the outstanding Registrable Securities are included in
such underwritten offering. The Holders participating in any underwritten
offering shall be responsible for any expenses customarily borne by selling
securityholders, including underwriting discounts and commissions and fees and
expenses of counsel to the selling securityholders and shall reimburse the
Company for the fees and disbursements of their counsel, their independent
public accountants and any printing expenses incurred in connection with such
underwritten offerings. Notwithstanding the foregoing or the provisions of
Section 6(a) hereof, upon receipt of a request from the Managing Underwriter or
a representative of Holders of a majority of the Registrable Securities
outstanding to prepare and file an amendment or supplement to the Shelf
Registration Statement and Prospectus in connection with an underwritten
offering, the Company may delay the filing of any such amendment or supplement
for up to 90 days if the Company in good faith has a valid business reason for
such delay.

        The Company shall in connection with an underwritten offering in
accordance with the provisions of this Section:

               (a) The Company shall, if requested, promptly include or
        incorporate in a Prospectus supplement or post-effective amendment to a
        Shelf Registration Statement, such information as the Managing
        Underwriters administering an underwritten offering of Registrable
        Securities registered thereunder reasonably request to be included
        therein and to which the Company does not reasonably object and shall
        make all required filings of such Prospectus supplement or
        post-effective amendment as soon as practicable after they are notified
        of the matters to be included or incorporated in such Prospectus
        supplement or post-effective amendment;

               (b) make such representations and warranties to the Holders and
        the underwriters in form, substance and scope as are customarily made by
        the Company to underwriters in primary underwritten offerings and
        covering matters, including, but not limited to, those set forth in the
        Purchase Agreement;



                                      -14-

<PAGE>   15



               (c) obtain opinions of counsel to the Company and updates thereof
        (which counsel and opinions (in form, scope and substance) shall be
        reasonably satisfactory to the Managing Underwriters) addressed to each
        Holder and the underwriters covering such matters as are customarily
        covered in opinions requested in underwritten offerings and such other
        matters as may be reasonably requested by such Holders and underwriters
        (it being agreed that the matters to be covered by such opinion or
        written statement by such counsel delivered in connection with such
        opinions shall include in customary form, without limitation, as of the
        date of the opinion and as of the effective date of the Shelf
        Registration Statement or most recent post-effective amendment thereto,
        as the case may be, the absence from such Shelf Registration Statement
        and the prospectus included therein, as then amended or supplemented,
        including the documents incorporated by reference therein, of an untrue
        statement of a material fact or the omission to state therein a material
        fact required to be stated therein or necessary to make the statements
        therein not misleading);

               (d) obtain "cold comfort" letters and updates thereof from the
        independent public accountants of the Company (and, if necessary, any
        other independent public accountants of any subsidiary of the Company or
        of any business acquired by the Company for which financial statements
        and financial data are, or are required to be, included in the Shelf
        Registration Statement), addressed to each Holder and the underwriters
        in customary form and covering matters of the type customarily covered
        in "cold comfort" letters in connection with primary underwritten
        offerings; and

               (e) deliver such documents and certificates as may be reasonably
        requested by any such Holders and the Managing Underwriters, including
        those to evidence compliance with Section 3(i) and with any customary
        conditions contained in the underwriting agreement or other agreement
        entered into by the Company.

        7.     MISCELLANEOUS.

               (a) Other Registration Rights. The Company may grant registration
rights that would permit any Person that is a third party the right to include
securities held by such Person on any Shelf Registration Statement, provided
that if the Managing Underwriter, if any, of such offering delivers an opinion
to the Holders that the total amount of securities which they and the holders of
such registration rights intend to include in any Shelf Registration Statement
is so large as to materially adversely affect the success of such offering
(including the price at which such securities can be sold), then only the
amount, the number or kind of securities to be offered for the account of
holders of such registration rights will be reduced to the extent necessary to
reduce the total amount of securities to be included in such offering to the
amount, number or kind recommended by the Managing Underwriter prior to any
reduction in the amount of Registrable Securities to be included.

               (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
modified or supplemented, and
