                         Report of Independent Auditors


The Board of Directors
Texas Instruments Incorporated

We have audited the accompanying statements of net assets acquired by Micron
Technology, Inc. of the MMP Business of Texas Instruments Incorporated ("MMP" as
defined in Note 1) as of December 31, 1997 and 1996, prepared pursuant to the
Agreement as defined in Note 1, and the related statements of operations and
cash flows for the years then ended. These statements are the responsibility of
the management of Texas Instruments Incorporated. Our responsibility is to
express an opinion on these statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statements of net assets acquired and the related
statements of operations and cash flows are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in these statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall presentation of these statements. We believe that our
audit provides a reasonable basis for our opinion.

In our opinion, the statements referred to above present fairly, in all material
respects, the net assets acquired by Micron Technology, Inc. of MMP at December
31, 1997 and 1996, pursuant to the Agreement as defined in Note 1, and the
results of its operations and its cash flows for the years then ended, in
conformity with generally accepted accounting principles.

1. BASIS OF PRESENTATION

Texas Instruments Incorporated ("TI") and Micron Technology, Inc. ("Micron")
entered into an acquisition agreement on June 18, 1998 under which Micron
acquired substantially all of TI's MOS memory products business ("MMP").  The
transaction closed on September 30, 1998 (the "Closing").  The accompanying
statements present the assets acquired and liabilities assumed ("Statements of
Net Assets Acquired") based upon the structure of the transaction as described
in the June 18, 1998 Acquisition Agreement and the First and Second Amendments
to the Acquisition Agreement executed on July 31, 1998 and September 30, 1998,
respectively. The Acquisition Agreement and amendments are together referred to
as the "Agreement," and this transaction is herein referred to as the
"Acquisition."  The statements of operations present the MMP business as it
historically operated within TI.

The Statements of Net Assets Acquired exclude significant assets and liabilities
of MMP as it historically operated within TI.  Under the terms of the Agreement,
certain assets of MMP are excluded from the Acquisition, including but not
limited to cash; intercompany receivables; selected equipment; tax assets;
receivables and inventory related to all 1 Meg DRAM, 4 Meg DRAM, EPROM, and
Flash product lines; and receivables related to grants from the Italian
government (see Note 13).  The Agreement also excludes certain liabilities of
MMP, including but not limited to long-term debt and related interest; tax
liabilities; obligations related to U.S. pension and retiree health care benefit
plans; and liabilities related to the Italian grant program (see Note 13).

MMP has experienced significant operating losses since 1995 and has been
dependent on TI for financial support in the form of working capital, equipment
and joint venture investment financings.

The statements have been prepared in accordance with generally accepted
accounting principles which require management to make estimates and assumptions
(including estimates of the net realizability of inventories and receivables,
useful lives of fixed assets, and the realizability of investments in joint
ventures) that affect the amounts reported in the statements.  Actual results
could differ from those estimates.  The statements are not intended to be a
complete presentation of the financial position, results of operations and cash
flows as if MMP had operated as a stand-alone company.   The Statement of Net
Assets Acquired at June 30, 1998 and the statements of operations and cash flows
for the six months ended June 30, 1998 and 1997 are unaudited and reflect all
adjustments which are of  a normal recurring nature (except as disclosed in the
notes to statements herein) and are, in the opinion of management, necessary to
present fairly the net assets acquired and the results of operations for the
periods shown.   Intercompany balances and transactions within MMP have been
eliminated.

MMP engages in research, development, manufacture, assembly, test, sales, and
distribution of MOS memory semiconductor devices.   The business supplies a
broad family of memory products, primarily dynamic random access memory ("DRAM")
devices and to a lesser extent erasable, programmable, read-only memory
("EPROM") and Flash devices, on a worldwide basis to manufacturers of computers,
telecommunications equipment, and automotive systems.

Micron did not acquire receivables or inventory related to EPROM and Flash
product lines.  Accordingly, the accompanying Statements of Net Assets Acquired
exclude receivables and inventory for these product lines.  During 1997 and
1996, revenues from these product lines were $157 million and $ 194 million,
respectively, which are included in the statements of operations.

TI provides various services to MMP including, but not limited to, facilities
management, data processing, security, payroll and employee benefits
administration, insurance administration, duplicating and telecommunications
services.  TI allocates these expenses and all other centrally managed operating
costs, first on the basis of direct usage when identifiable, with the remainder
allocated among TI's businesses on the basis of their respective revenues,
headcount, or other measures.  In the opinion of management of TI, these methods
of allocating costs are reasonable.  These expenses totaled $150 million and
$199 million in 1997 and 1996, respectively.

Revenues are recorded upon shipment of products to distributors and original
equipment manufacturers.  The revenue for shipments to distributors is reduced
for estimated returns, price protection and allowance rights.  Revenues from
products sold by MMP to affiliates of TI (excluding joint ventures--see Note 12)
are insignificant. During 1997, a customer terminated a long-term purchase
agreement with MMP.  As a result of such termination, both 1997 revenues and
gross margins increased by approximately $34 million due to the accelerated
recognition of a previously received non-refundable deposit from the customer.

MMP participates in a centralized cash management system wherein cash receipts
are transferred to and cash disbursements are funded by TI.  Since cash and cash
equivalents related to MMP operations will not be acquired by Micron, they are
excluded from the Statements of Net Assets Acquired.

MMP operations are included in the consolidated income tax returns of TI.
Pursuant to the Agreement, TI retained income, as well as other tax liabilities
and rights to any tax refunds relating to operations prior to the Closing.
Accordingly, the Statements of Net Assets Acquired do not reflect current or
prior period income or other tax receivables or payables. The income tax
provisions included in the statements of operations have been determined on a
hypothetical basis as if  MMP were a separate taxpayer.  The tax provision
consists of hypothetical current foreign taxes on foreign income resulting from
intercompany transfer pricing requirements.  No hypothetical tax benefit for
U.S. losses has been reflected in the provision due to the uncertainty of
realization.

The U.S. dollar is the functional currency for financial reporting.  With regard
to accounts recorded in currencies other than U.S. dollars, current assets
(except inventories), other assets, current liabilities, and long-term
liabilities are remeasured at exchange rates in effect at year end.
Inventories, property, plant and equipment and depreciation thereon are
remeasured at historic exchange rates. Revenue and expense accounts other than
depreciation for each month are remeasured at the appropriate month-end rate of
exchange.  Transaction gains and losses are not significant and have been
excluded from the statements of operations.

During the second quarter of 1998, MMP terminated certain purchase contracts
resulting in charges against operations of approximately $42 million.  In
connection with these terminations, MMP committed to purchase $18 million of
certain test equipment during the second half   of 1998.

Upon execution of the acquisition agreement on June 18, 1998, MMP discontinued
certain product research and development efforts.

Other significant accounting policies are described below as an integral part of
the notes to financial statements to which the policies relate.

Certain trade accounts receivable have been allocated by TI to MMP, primarily
those in Singapore and Europe.  At December 31, 1997 and 1996, such allocated
receivables were $61 million and $38 million, respectively.  TI allocated these
amounts based upon net revenues.

Inventories are stated at the lower of cost or estimated realizable value.  Cost
is generally computed on a currently adjusted standard, which approximates
current average costs. Average selling prices of 16 Meg DRAM products declined
approximately 84% in 1996 and 55% in 1997.  Subsequent to December 31, 1997,
average prices continued to decline 42% through June 30, 1998, then average
prices declined a further 20% through August 31, 1998.  While the realizability
of inventories are affected by changes in average selling prices, the direct
risk from such changes has partially been mitigated  by inventory supply
arrangements with joint ventures whereby inventory costs of MMP are determined
based upon discounts from MMP's average selling prices (see Note 12).

As discussed in Note 12, MMP amended pricing terms with certain joint ventures
in the second quarter of 1998 effectively resulting in fixed prices to be paid
by MMP to the joint ventures generally exceeding average selling prices.

4. PROPERTY, PLANT, AND EQUIPMENT

Property, plant, and equipment is stated at cost less accumulated depreciation.
Depreciation is computed primarily using the sum-of-the-years-digits method for
buildings and improvements and the 150% declining-balance method for machinery
and equipment. Fully depreciated assets are written off against accumulated
depreciation. Maintenance and repairs are charged to expense.

</TABLE>

7. LONG-TERM DEBT

Certain long-term debt and the related interest expense of TI is attributed to
MMP.  This debt relates to Italian lira mortgage notes (of an Italian subsidiary
of TI) collateralized by real estate and building equipment at the Avezzano
wafer fabrication facility.  TI has provided certain guarantees on the full
amount of this outstanding debt.  The carrying amount of the collateral was $114
million at December 31, 1997.  Outstanding Italian lira notes amounted to $198
million and $209 million, respectively, at December 31, 1997 and 1996.  Interest
paid on loans was $10 million in 1997 and $7 million in 1996. Under the terms of
the Agreement, Micron did not assume long-term debt or related accrued interest
of MMP.

8. RISK CONCENTRATION

Financial instruments which potentially subject MMP to concentrations of credit
risk primarily include accounts receivable.  Concentrations of credit risk with
respect to the receivables are limited due to the large number of customers in
MMP's customer base, and their dispersion across different geographic areas
(U.S., Europe, and Asia).  MMP conducts ongoing credit evaluations of customers
and generally does not require collateral or other security.  MMP maintains an
allowance for losses based upon the expected collectibility of accounts
receivable.  Historically, MMP has not incurred any significant credit-related
losses.

9. STOCK OPTIONS

Stock options have been granted to MMP employees under the Texas Instruments
1996 Long-Term Incentive Plan, approved by TI stockholders on April 18, 1996.
Options have also been granted under the 1984 and 1988 Stock Option Plans and
the Texas Instruments Long-Term Incentive Plan; however, no further options may
be granted under these plans.  Under all these stockholder-approved plans, the
option price per share may not be less than 100 percent of the fair market value
on the date of the grant.  Substantially all of the options have a 10-year term.
Options granted in 1997 generally vest ratably over four years.  Options granted
prior to that are either fully vested or will vest within one year.

MMP employees also have stock options outstanding under an Employee Stock
Purchase Plan approved by TI stockholders in 1997.  The plan provides for
options to be offered semiannually to all eligible employees in amounts based on
a percentage of the employee's compensation.  The option price per share may not
be less than 85 percent of the fair market value on the date of grant.  If the
optionee authorizes and does not cancel payroll deductions, options granted
become exercisable after 7 months, and expire not more than 13 months, from the
date of grant.  Options are also outstanding under the 1988 Employees Stock
Option Purchase Plan; however, no further options may be granted under this
plan.

In connection with the Acquisition, vested options in TI stock under the Long-
Term Incentive Plans (for TI employees who accept employment offers with Micron)
will continue to exist based upon the original terms of the option grants.  Upon
termination from Micron, employees will have 30-90 days to exercise the options.
Unvested options in TI stock will be substituted with Micron stock.  All options
of the Employee Stock and Stock Option Purchase Plans were exercised at Closing
unless employees chose to cancel the options prior to Closing.

In accordance with the terms of APB No. 25, MMP has not recorded compensation
expense for TI stock option awards to employees of the MMP Business.  As
required by SFAS No. 123, the following disclosures of hypothetical values for
stock option awards are provided below.

The weighted-average grant-date value of options granted during 1997 and 1996
was estimated to be $15.72 and $9.24 under the Long-Term Incentive Plans (Long-
Term Plans) and $13.47 and $6.05 under the Employee Stock and Stock Option
Purchase Plans (Employee Plans).  These values were estimated using the Black-
Scholes option-pricing model with the following weighted-average assumptions for
1997 and 1996:  expected dividend yields of .93% and 1.48% (Long-Term Plans) and
 .70% and 1.21% (Employee Plans); expected volatility of 39%; risk-free interest
rates of 5.76% and 5.42% (Long-Term Plans) and 5.69% and 6.15% (Employee Plans);
and expected lives of 6 years (Long-Term Plans) and .8 years and 1.5 years
(Employee Plans).  Compensation expense based on these hypothetical values would
not have been material in 1997 and 1996.

Summarized information about stock options outstanding under the Long-Term Plans
and 1984 and 1988 Stock Option Plans at December 31, 1997 for employees of MMP,

10. CONTINGENCIES AND COMMITMENTS

Contingencies:  TI is subject to various lawsuits, claims and proceedings
arising out of the normal conduct of the MMP business.  TI management believes
the disposition of matters which are pending or asserted will not have a
material adverse effect on the financial statements of MMP.

Commitments:  MMP occupies various facilities which are either owned or leased
by TI.  The statements of operations include occupancy charges from TI which
include depreciation, rent, and taxes (as applicable) incurred by TI and charged
to MMP based on facilities occupied.  These charges do not necessarily represent
current market rates to lease such facilities.  TI has executed lease agreements
with Micron at agreed-upon rates in connection with TI-owned facilities that
will be utilized by Micron after the Closing.  The rent expense associated with
these agreements is immaterial.

                                       10
<PAGE>
 
MMP also directly leases certain facilities and equipment from third parties
under operating leases, many of which contain renewal options and escalation
clauses.  Total rental expense on such operating leases amounted to $3 million
in 1997 and 1996.   Future rental commitments under leases at December 31, 1997
were immaterial.

11. PROFIT SHARING AND RETIREMENT PLANS

MMP participates in various incentive plans provided by TI for its employees,
including general profit sharing and savings programs as well as annual
performance awards.  It also participates in TI pension and retiree health care
benefit plans in the U.S. and pension plans in certain non-U.S. locations.
Pursuant to the Agreement, no liabilities pertaining to U.S. pension and retiree
medical plans for employees of MMP were assumed by Micron;  therefore, no
obligations related to these plans are reflected in the statements of net assets
acquired.

PROFIT SHARING

Profit sharing expense has been allocated to MMP by TI based on relative payroll
costs.  Profit sharing expense was $9 million in 1997.  There was no profit
sharing expense in 1996.  Profit sharing liabilities attributed to non-U.S. MMP
employees have been included in the statements of net assets acquired.

SAVINGS PROGRAM

In the U.S., MMP employees participate in the TI matched savings program whereby
employees' contributions of up to 4% of their salary are matched by TI at the
rate of 50 cents per dollar.  Contributions are subject to statutory
limitations.  The contributions may be invested in several investment funds
including TI common stock.  The expense under this program charged by TI to MMP
was immaterial in 1997 and 1996.

PENSION PLANS

In the U.S., TI has a defined benefit plan which covers MMP employees and
provides benefits based on years of service and employee's compensation.  The
plan is a career-average-pay plan which has been amended periodically in the
past to produce approximately the same results as a final-pay type plan.  TI's
funding policy is to contribute to the plan at least the minimum amount required
by ERISA.  Pension expense for MMP in the U.S. was immaterial in 1997 and 1996.

Retirement coverage for non-U.S. MMP employees is provided through separate
plans.  Retirement benefits are based on years of service and employee's
compensation, generally during a fixed number of years immediately prior to
retirement.  Funding policy is based on local statutes.  Pension expense of the
non-U.S. plans covering MMP employees was $4 million in 1997 and $5 million in
1996.  The non-U.S. plans are not funded.  The accrued pension as well as the
vested, accumulated, and projected benefited obligations for the non-U.S. plans
amounted to approximately $17 Million at December 31, 1997 and 1996.

12. JOINT VENTURES

The following is a discussion of TI's interests in certain joint ventures
("JV's") which are ascribed to MMP.  The JV agreements do not provide for
transference of an investor's interest without approval of the other investors.

MMP has held minority ownership in, and long-term inventory purchase commitments
with, four JV's, each formed to construct and operate advanced wafer fabrication
facilities for the manufacture of DRAM products.  Three of the JV's are located
outside the U.S.  Under the JV agreements, TI purchases and takes delivery of
the output of the JV's at prices based upon percentage discounts from TI's
average selling prices.  Although these pricing arrangements were designed to
help reduce the effect of market volatility on MMP,  their effectiveness has
been limited due to the sharp declines in average unit prices experienced since
1995.  Certain co-venturers have had the right to buy a portion of the output
from MMP.

MMP accounts for its investments in non-U.S. JV's as inventory supply
arrangements.  The purpose of the non-U.S. JV's is to provide 100% of their
semiconductor output to MMP (certain co-venturers have the right to purchase
such output from TI).  As a result, MMP expects to recover its cost of the non-
U.S. JV's through sale of the semiconductor output, and is amortizing its cost
of the ventures over the expected initial output period of 3 to 5 years, and
recognizing its share of any cumulative JV net losses in excess of amortization.
The related expense for 

                                       11
<PAGE>
 
such amortization charged to operations for the non-U.S. JV's was $21 million in
1997 and $14 million in 1996. MMP accounts for its investment in the U.S. JV
(see Twinstar below), which is operationally different from the non-U.S. JV's,
under the equity method of accounting (on a one-quarter lag basis). MMP
recognized $67 million in 1997 and $19 million in 1996 for its share of the U.S.
JV's net losses under the equity method.

Under various bank financing arrangements, TI has provided certain guarantees of
JV obligations.  Under the joint venture agreements, certain organizational and
operational decisions can only be made by super-majority agreement of the
ventures.   In addition, MMP has agreements to receive payments from each of the
joint ventures to provide certain engineering support, training, and technology
transfers to assist in the establishment and maintenance of advanced wafer
fabrication facilities.

Inventory purchases from the JV's aggregated $977 million in 1997 and $1176
million in 1996. MMP's assembly/test facility in Singapore performs
manufacturing activities for the JV's.  Revenues from these activities were $203
million and $323 million in 1996 and 1997 and are included as credits to cost of
revenues in the statements of operations.  A significant decline in revenues and
margins generated from the assembly/test facility is anticipated for 1998 due to
tighter market conditions and reduced operating plans commensurate with the
decline in assembly/test purchase commitments from the Twinstar and TI-Acer
JV's. Receivables from and payables to the JV's were $135 million and $69
million at December 31, 1997, and $44 million and $66 million at December 31,
1996.

Each DRAM joint venture arrangement is described below.  Under the terms of the
Agreement, Micron acquired all of TI's capital stock in the TECH and KTI joint
ventures.

TECH
- ----

TECH Semiconductor Singapore Pte. Ltd. ("TECH") is a joint venture between TI,
the Singapore Economic Development Board ("EDB"), Canon Inc. ("Canon"), and
Hewlett-Packard Company ("HP") formed in 1991 for purposes of constructing and
operating a manufacturing facility in Singapore.  As of December 31, 1997 and
1996, TI owned 27.25% of this joint venture.  During the second quarter of 1998,
TI increased its ownership interest to 29.93% by providing an equity
contribution of $31 million.

Under the related purchase agreement between TI and TECH, MMP is required to buy
100% of DRAM units produced by TECH, and HP and Canon hold an option to purchase
products from TI (as specified in the shareholders' agreement between the co-
venturers).  The pricing terms for products purchased from TECH by TI were based
upon a percentage discount from TI's average selling price of DRAM products
during the previous quarter.  During the second quarter of 1998, TI amended the
pricing terms with TECH such that the price paid for products supplied by the
joint venture is fixed if average selling prices fall below specified levels.

TI was contingently liable at December 31, 1997 and 1996 for $11 million under a
debt guarantee provided by TI as part of the joint venture.  In addition, if
TECH does not maintain certain debt service coverage requirements, TI must
deposit a portion of price discounts received from TECH into an escrow account
not to exceed $100 million.  No such deposits were required prior to 1998.  TI
deposited $8 million, $5 million, and $3 million into the escrow account during
the first, second, and third quarters of 1998, respectively.  Such amounts were
expensed as paid in 1998.  Under the terms of the Agreement, TI retains rights
to the escrow account.

KTI
- ---

KTI Semiconductor Limited ("KTI") is a joint venture between TI and Kobe Steel,
Ltd. ("Kobe") formed in 1990 for purposes of constructing and operating a
manufacturing facility in Japan.  As of December 31, 1997 and 1996, TI owned 25%
of this joint venture.  During the first quarter of 1998, TI, in coordination
with a Kobe equity contribution, provided an equity contribution of $48 million
to the joint venture and maintained its ownership interest of 25%.  During the
second quarter of 1998, TI loaned approximately $38 million to KTI.  The
receivable associated with the loan was not acquired by Micron.

Under the related purchase agreement between TI and KTI, TI is required to buy
100% of DRAM units produced by KTI.  The pricing terms for products purchased
from KTI by TI were based upon a percentage discount from TI's average selling
price of DRAM products during the current quarter.  During the second quarter of
1998, TI amended 

                                       12
<PAGE>
 
the pricing terms with KTI such that the price paid for products supplied by the
joint venture is fixed. This fixed price exceeded current average selling prices
as of the end of the second quarter of 1998.

Under the joint venture arrangement, TI agreed to indemnify 25% of Kobe's
guarantee of certain KTI debt.  At December 31, 1997 and 1996, TI was
contingently liable for $8 million and $14 million, respectively, for such
guarantee.

TI-Acer
- -------

Until June, 1998, Texas Instruments - Acer Incorporated ("TI-Acer") was a joint
venture between TI, Acer Incorporated ("Acer"), and the China Development
Corporation formed in 1990 for purposes of constructing and operating a
manufacturing facility in Taiwan.  As of December 31, 1997 and 1996, TI owned
33.33% of this joint venture.

Under the related purchase agreement between TI and TI-Acer, TI was required to
buy 100% of DRAM units produced by TI-Acer, and Acer held an option to purchase
up to 50% of such products from TI (as specified in the shareholders' agreement
between the co-venturers).  The pricing terms for products purchased from TI-
Acer by TI were based upon percentage discounts (depending upon Acer operating
results) from TI's average selling price of DRAM products during the current
quarter.

On March 3, 1998, TI and Acer entered into a stock purchase agreement whereby
Acer agreed to purchase all of TI's equity interest in TI-Acer for $120 million
cash.  The sale of TI's interest in TI-Acer closed on June 10, 1998, and TI
recorded a gain to TI of approximately $83 million in the second quarter of
1998.  In connection with the stock purchase agreement, a termination and
release agreement was executed between TI, Acer, TI-Acer, and other minority
investors whereby TI was released from all claims associated with TI-Acer.  In
addition, a transition agreement was executed whereby MMP would purchase a
specified supply of DRAM units from the former TI-Acer between June 10, 1998 and
September 30, 1998 at a fixed price.  This fixed price exceeded current average
selling prices as of the end of the second quarter of 1998.  TI also agreed to
provide up to $20 million of interest-free working capital financing through MMP
to the former TI-Acer to be repaid to TI in the second half of 1998.

Under the terms of the Agreement, Micron will not invest in or continue an
inventory supply arrangement with the former TI-Acer.  Accordingly, MMP's
investment in this joint venture as of December 31, 1997 and 1996 has not been
included in the statements of net assets acquired.  Inventory purchases from TI-
Acer were $379 million in 1997 and $535 million in 1996.  Revenues from
assembly/test manufacturing activities performed by MMP for TI-Acer were $124
million in 1997 and $130 million in 1996.

Twinstar
- --------

TwinStar Semiconductor Incorporated ("Twinstar") was a joint venture formed in
1994 between TI and Hitachi, Ltd. ("Hitachi") for purposes of constructing and
operating a manufacturing facility in Richardson, Texas.  As of December 31,
1997 and 1996, TI owned 36.5% and 27.4%, respectively, of this joint venture.

Under the related purchase agreement between TI, Hitachi, and Twinstar, the DRAM
units produced by Twinstar were required to be purchased by TI and Hitachi at a
50/50 ratio.  The pricing terms for products purchased from Twinstar by TI were
based upon percentage discounts (depending upon Twinstar operating results) from
TI's average selling price of DRAM products during the current quarter.  Both
MMP and Hitachi had agreements to receive payments from the joint venture to
provide certain engineering support, training, and technology transfers to
assist in the establishment and maintenance of advanced wafer fabrication
facilities.

In February, 1998, TI and Hitachi executed an agreement to discontinue their
joint venture arrangement, with TI purchasing the JV's assets.  Under the terms
of the agreement, which closed in March, 1998, all borrowings and original bank
equity investments were repaid by TI and Hitachi, and a newly created subsidiary
of TI, Texas Instruments Richardson, LLC ("TIR"), was formed to become the sole
owner of all assets and liabilities of the former Twinstar joint venture.  Such
net assets in the joint venture consisted primarily of working capital and
property, plant and equipment and were valued at approximately $100 million at
acquisition.  During the first quarter of 1998, MMP recognized a pretax charge
of $219 million, which is included in cost of revenues,  in connection with the
termination of the Twinstar joint venture.

In June, 1998, TI announced termination of TIR operations effective immediately.
MMP recorded shut down costs in second quarter 1998 of approximately $37 million
(included in cost of revenue), primarily comprised of employee severance,
contract cancellation costs, and inventory write-offs.  Under the Agreement,
Micron has acquired the assets and assumed certain liabilities of TIR.

13. GRANTS FROM ITALIAN GOVERNMENT

MMP participates in a grant program with the Italian government whereby grants
are received from the government as reimbursement for certain purchases of
capital equipment and  facilities as well as research and development/training
costs incurred as part of operations in Avezzano.  These grants have been issued
to MMP in phases, and MMP is required to maintain use of the related equipment
and facilities for a designated time period after the Closing.

During 1997 and 1996, MMP participated in two phases of the program.  Prior to
1996, the MMP Business accounted for grants received under Phase I and II of the
program using a modified cash basis whereby cash received from the government
was recognized in operating results when received over a one year period from
the date of receipt. The modified cash basis was utilized by MMP due to
collectibility delays experienced in previous years with the Italian government.
During 1995, MMP's experience with grant collections improved significantly.
Accordingly, effective January 1, 1996, the MMP Business adopted the accrual
method for Phase II grants.  At that time, substantially all grants under Phase
I had been collected.  Under the accrual method, the MMP Business recognizes
grants in operating results over the period necessary to match the grants
received with related costs incurred which were eligible for reimbursement under
the program.

In 1996,  the MMP Business received $52 million in cash for Phase II grants and
recognized $97 million for Phase I and II grants as credits to research and
development and capital depreciation in the statements of income.  In 1997, the
MMP Business received $36 million in cash and recognized $35 million for Phase
II grants as credits to research and development and capital depreciation.

In accordance with the terms of the Agreement, receivables from the Italian
government and deferred credits for cash received under the grant program have
not been included in the Statements of Net Assets Acquired.

14. BUSINESS SEGMENT AND GEOGRAPHIC AREA DATA

Effective for the year ended December 31, 1997, MMP adopted SFAS No. 131, which
requires a new basis of determining reportable business segments, i.e., the
management approach.  This approach designates that the source of business
segments within an entity is the internal organization used by management for
making operating decisions and assessing performance. MMP operates in one
business segment:   semiconductor memory products.

Selected geographic data for MMP is presented below for the years ended December
31, 1997 and 1996.  Trade revenues are based on product shipment destination,
and property, plant and equipment is based on physical location (in millions of
dollars):

15. YEAR 2000 (UNAUDITED)

TI's plan to address Year 2000 issues has included the MMP business.  Based on
assessments to date, TI believes current MMP products are ready for Year 2000.
Obsolete and discontinued products, as well as previously divested product
lines, have not been included in these assessments.  The extent to which Micron
adopts or modifies the strategy TI has undertaken with regard to MMP or how
Micron will integrate MMP into its own strategy regarding the Year 2000 is not
known.

(b)  Pro Forma Financial Information
       ----------------------------------------

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

MICRON/MMP COMBINED COMPANY

Basis of Presentation
- ---------------------

Texas Instruments Incorporated ("TI") and Micron Technology, Inc. ("Micron")
entered into an acquisition agreement dated as of June 18, 1998, as amended as
of July 31, 1998 and September 30, 1998, respectively (the "Agreement"),
pursuant to which Micron agreed to acquire substantially all of TI's memory
products business, including the acquisition of certain assets and the
assumption of certain liabilities (the "Acquired Business"). For purposes of
the unaudited pro forma combined financial statements in this Item 7(b), "MMP"
refers to the Acquired Business together with those operations, assets and
liabilities not acquired by Micron under the Agreement but which constitute a
part of TI's memory products business as conducted by TI historically, except
as noted herein. The transaction closed on September 30, 1998 (the "Closing").
The transaction described in the Agreement is herein referred to as the
"Acquisition."

The following unaudited pro forma combined financial statements are based upon
the consolidated financial statements of Micron and the Acquired Business,
combined and adjusted to give effect to the Acquisition.

The following unaudited pro forma combined statements of income for the year
ended August 28, 1997 and for the nine months ended May 28, 1998  give effect to
the Acquisition as if it had occurred on August 30, 1996 and August 29, 1997,
respectively.  The unaudited pro forma combined statements of income for the
year ended August 28, 1997 were prepared based upon the audited consolidated
statement of income of Micron for the year ended August 28, 1997 and the
unaudited statements of income of MMP for the twelve months ended June 30, 1997.
The unaudited pro forma combined statements of income for the nine months ended
May 28, 1998 were prepared based upon the unaudited consolidated statement of
income of Micron for the nine months ended May 28, 1998 and the unaudited
statement of income of MMP for the nine months ended March 31, 1998.

The following unaudited proforma combined balance sheets as of May 28, 1998,
give effect to the Acquisition as if it had occurred on such date and were
prepared based upon the unaudited consolidated balance sheet of Micron as of May
28, 1998, and the unaudited statement of net assets acquired for the Acquired
Business as of March 31, 1998.

These unaudited pro forma combined financial statements and the notes thereto
should be read in conjunction with Micron's Form 10-Q for the interim period
ended May 28, 1998 and the Company's Form 10-K, as amended, for the year ended
August 28, 1997, and the audited financial statements of the MMP Business of TI,
including the notes thereto (see Item 7(a)).  The financial statements of the
MMP Business of TI, including the notes thereto, present MMP, except as noted
therein and herein, and are not limited to the results of operations and cash
flows of the Acquired Business.

The Acquisition will be accounted for by the purchase method of accounting.
Accordingly, Micron's cost to acquire the Acquired Business (the "Purchase
Consideration") of approximately $830 million, net of cash proceeds, will be
allocated to the assets acquired and liabilities assumed according to their
respective fair values, with any excess Purchase Consideration being allocated
to goodwill.  The Purchase Consideration is based on the approximate market
price of Micron's Common Stock ($22.7) when the transaction was announced and
the estimated market value of the Convertible Notes and the Subordinated Notes
on the date of issuance (approximately 90% and 80% of par value, respectively).
The final allocation of the Purchase Consideration is dependent upon the
completion of certain valuations and other studies.  Accordingly, the purchase
allocation adjustments made in connection with the development of the unaudited
pro forma combined financial statements are preliminary and subject to change.

The unaudited pro forma combined financial statements are not necessarily
indicative of the results of operations or financial position of the combined
company that would have occurred had the Acquisition occurred at the beginning
of the period presented or on the date indicated, nor are they necessarily
indicative of future operating results or financial position.

                                       16
<PAGE>
 
The Acquisition is expected to have a significant effect on the Company's future
results of operations and cash flows, including, but not limited to: a
considerable negative impact on gross margin in the near term due in part to
significantly higher per unit manufacturing costs at the acquired facilities;
costs related to the assimilation of the acquired operations; increased interest
expense associated with the Convertible Notes and Subordinated Notes issued; an
increase in capital spending relating to the acquired facilities; and the
potential for further downward pressure on the average selling prices the
Company receives on its semiconductor memory products.  In addition, the
creation of intangible assets associated with the purchase could result in
significant future amortization expense.

The pro forma excess of Purchase Consideration over the historical net book
value of the Acquired Business net assets acquired as of September 30, 1998 is
estimated to be approximately $200 million, and principally represents a ten
year royalty-free patent cross license between TI and Micron which is expected
to be amortized over a period of not more than ten years. Excess Purchase
Consideration was also allocated to joint venture supply contracts, equity
investments in joint ventures, property, plant and equipment, acquired software
and software licenses, an established workforce and other miscellaneous assets.

The Company is in the process of completing the valuations and other studies of
the significant assets, liabilities and business operations of the Acquired
Business. Using this information, Micron will make a final allocation of the
Purchase Consideration, including allocation to tangible assets and liabilities,
identifiable intangible assets and goodwill.

                          NOTES TO UNAUDITED PRO FORMA
                         COMBINED FINANCIAL STATEMENTS

Pro forma adjustments giving effect to the Acquisition in the unaudited pro
forma combined statements of income reflect the following:

(a)  Exclusion of historical MMP revenues and costs for product sourced from the
     former Texas Instruments  Acer Incorporated ("TI-Acer") and exclusion of
     historical amortization of TI-Acer supply contracts.  Under the terms of
     the Agreement, Micron will not invest in or continue an inventory supply
     arrangement with the former TI-Acer.  (See notes to MMP historical
     financial statements.)
(b)  Exclusion of historical MMP revenues and costs for FLASH, certain 4 Meg
     DRAM, and EPROM products, as inventory for such products is not included as
     part of the Acquisition.
(c)  Depreciation and amortization of assets arising from the allocation of
     excess Purchase Consideration over the historical net book value of MMP net
     assets acquired, including joint venture supply contracts, property, plant
     and equipment, an established workforce, acquired software and software
     licenses and other miscellaneous assets, as well as the effects of equity
     accounting relating to joint ventures.  Pro forma adjustments are net of
     historical MMP depreciation and amortization.  The ten-year royalty-free
     patent cross license between TI and Micron pursuant to the Agreement does
     not commence until January 1, 1999, and therefore pro forma adjustments for
     the periods presented do not reflect amortization expense for this license.
(d)  Adjustment to research and development expense and capital depreciation to
     exclude income statement effects of MMP's grant program with the Italian
     government.  (See notes to MMP historical financial statements.)
(e)  Adjustment to historical MMP selling, general and administrative expense to
     exclude expense associated with employees not hired in the Acquisition.
(f)  Interest expense for $740 million principal amount of seven-year, 6.5%
     notes convertible into an additional 12.3 million shares of Micron Common
     Stock, and $210 million principal amount, seven-year, 6.5% subordinated
     notes, net of estimated interest income on cash proceeds.  The if-converted
     method was applied to determine the appropriate effect on earnings per
     share for the convertible notes.  Conversion was not assumed as the effect
     to earnings per share would have been anti-dilutive.
(g)  Exclusion of MMP interest expense for Italian lira mortgage notes (of an
     Italian subsidiary of TI).  These notes will not be assumed by Micron as a
     part of the acquisition.
(h)  Income tax effect of pro forma adjustments and to present income tax
     expense at the statutory rate.
(i)  Effect on earnings per share from the issuance of 28,933,092 unregistered
     shares of Micron Common Stock to Texas Instruments, Inc.

Pro forma adjustments giving effect to the Acquisition in the unaudited pro
forma combined balance sheets reflect the following:

(a)  Receipt of $550 million in cash pursuant to the terms of the Agreement, as
     amended.
(b)  Pro forma cash payment due pursuant to a requirement of the Agreement, as
     amended, which requires the parties to make cash adjustments to ensure
     that with respect to the Acquired Business, current acquired assets minus
     the sum of current and noncurrent assumed liabilities ("working capital")
     is $150 million at closing. While the final Acquired Business closing
     statement of net assets is not yet available, the financial position of
     Acquired Business at closing is expected to differ significantly from the
     financial position of Acquired Business reflected in the unaudited pro
     forma combined balance sheets as of May 28, 1998. The actual working
     capital cash adjustment is expected to require a cash payment from TI to
     Micron in excess of $100 million. Final determination of the working
     capital adjustment is subject to a post-closing audit.
(c)  Excess Purchase Consideration over net assets acquired, including a ten-
     year royalty-free patent cross license agreement, property, plant and
     equipment, joint venture supply contracts, equity investment in joint
     ventures, acquired software and software licenses, an established workforce
     and other miscellaneous assets.
(d)  Accrual of estimated acquisition costs.
(e)  Issuance of $740 million principal amount of seven-year, 6.5% notes
     convertible into an additional approximately 12.3 million shares of Micron
     Common Stock, and a $210 million principal amount, seven year, 6.5%
     subordinated note.  The notes will be recorded at estimated market values
     of 90% and 80% of par value, estimated as of the date of closing.
(f)  Issuance of 28,933,092 unregistered shares of Micron Common Stock to Texas
     Instruments, Inc., the value of which is based on the approximate market
     price of Micron's Common Stock ($22.7 per share) when the transaction was
     announced on June 18, 1998.

          meaning of Code Section 1313(a)) or any other event which finally
          and conclusively establishes the amount of any liability for Taxes.
          In the event that the Price Allocation is disputed by any Taxing

               pursuant to the GT Projects, the Orion Project, or Project M,
               respectively, such license to grant rights to Buyer to develop,
               manufacture, have manufactured, use, sell, import or otherwise
               dispose of semiconductor products for the respective lives of
               the know-how, trade secret, copyright, and mask work rights.

                      (iii)  With respect to patents jointly owned by Seller

               enforce such joint patent to or against Buyer on terms that
               would require Buyer to pay or offer any consideration of any
               kind in exchange for such license. The terms "joint patents"
               and "licensing framework" shall have the meaning ascribed to

                  (d)  Notwithstanding any other indemnity provision in this
          Agreement or any agreement or amendment associated with this
          Agreement, and not subject to any limitations on any other indemnity
          provision in this Agreement or any agreement or amendment associated
          with this Agreement, Seller agrees to indemnify, defend and hold Buyer
          and any Buyer subsidiary, including their respective directors,
          officers, employees and agents harmless with respect to any claim that
          any manufacture, use, sale, offer to sell or importation of any
          product, any combination of such product with any other hardware
          and/or software, any method or process used in the manufacture or
          testing of such product, or any tools or equipment used for
          accomplishing any of the foregoing infringes (a) any know how, trade
          secret, copyright or mask work rights of the Eagle Consortium to which
          Buyer received a license under subparagraph 1, above, (b) any Joint
          Patent arising out of the GT Projects or the Orion Project, or (c) any
          patent arising out of or resulting from the Eagle Consortium. This
          indemnity shall apply regardless of whether such claim is brought by
          Hitachi, Mitsubishi, parties to the Eagle Consortium, or any successor
          in interest to any intellectual property identified in (a), (b) and
          (c) herein. Seller agrees to pay all costs, expenses and fees arising
          out of defense and investigation of such claim, including any and all
          damages award or settlement amount resulting therefrom. In the event
          an injunction is obtained against activities of Buyer or its
          subsidiaries, Seller shall use all commercially reasonable efforts to
          procure for Buyer the right to continue the activities which resulted
          in the claim.

               6.34  Transfers of Acquired Intellectual Property.  To permit
                     -------------------------------------------            
          Buyer to specifically document the assignment of specific items of
          Intellectual Property transferred to Buyer as Acquired Intellectual
          Property, or to facilitate the recordation of such assignments, the
          parties agree that it is desirable to have specific documents of
          assignment. Accordingly, attached hereto as Exhibit N is an
          "Assignment of Trademarks" currently recognized to be included within
          Acquired Intellectual Property. To the extent that additional
          trademarks may be identified within the Acquired Intellectual
          Property, the parties agree that an assignment in the form of Exhibit
          N may be utilized to document such assignment. Similarly, attached
          hereto as Exhibit O is a "Form of Copyright Assignment" which the
          parties agree is appropriate for use to document the assignment(s) of
          Copyrights included within Acquired Intellectual Property, as agreed
          upon by the parties subsequent to Closing.

               6.35  Backlog.  Backlog of DRAM products on the books of the
                     -------                                               
          Seller Group as of the Closing Date and scheduled for delivery to any
          Seller Group customer (other than distributors) within thirty (30)
          days of the Closing Date shall, to the extent such commitments were
          entered into in the normal course of the Business consistent with past
          practices, become backlog of Buyer or one of its Subsidiaries, which
          shall honor applicable price, quantities and delivery dates; provided
          that if Buyer or its Subsidiary reasonably determines that price,
          quantities, delivery dates, credit or payment terms associated with
          such backlog are not consistent with its

                                       10
<PAGE>
 
          customary policies and Buyer or its Subsidiary is unable to negotiate
          acceptable terms with such customer, Buyer or its Subsidiary may
          reject such backlog. Backlog scheduled for delivery to, and DRAM
          inventory held at, the common distributors designated in the letter
          agreements attached hereto as Exhibit P shall be treated in accordance
          with the provisions of such letter agreements. The Seller Group shall
          exercise commercially reasonable efforts to avoid scheduling backlog
          for delivery within five (5) Business Days of the Closing Date.

     Section 36.    Section 6.6 of the Acquisition Agreement is amended by
deleting Section 6.6 in its entirety and by replacing it with the following:

          terminating on the earlier to occur of (x) the publication in the
          Italian Official Gazette of a CIPE resolution stating that investment
          under the 1989 Program Contract is complete (the "Publication Date")
          or (y) 18 months after the Closing Date; provided, however, that
                                                   --------  -------
          Italian Newco shall be entitled to terminate Italian Newco employees
          for good reason and shall be allowed to reduce employment levels
          through Italian Newco employee attrition; provided, further, that in
                                                    --------  -------

          shall cause employment levels in Italian Newco to remain at least
          equal to the Required Employment Levels as in effect from time to time
          for a period commencing on the earlier of (i) the Publication Date and
          (ii) 18 months after the Closing Date and terminating 30 months from

                                   --------  ------- 
          restriction extend

                                       11

          on the earlier to occur of (x) the Facility Restriction Expiration
          Date for any particular Restricted Facility Portion or (y) 30 months

          Portion for the manufacture of electronics products at levels of
          activity that in the aggregate are substantially consistent with
          activity levels at the Closing Date, taking into account the
          contemplated conversion of the 6-inch line to the 8-inch line and the
          implementation of new technology provided, however, that in no event
                                           --------  -------

          any of its Affiliates with respect to any Restricted Facility Portion
          to the extent Buyer or its Affiliates obtain approval in accordance

          applicable from time to time, (ii) the Equipment Restriction
          Expiration Date with respect to any item of Restricted Equipment, and
          (iii) the Facility Restriction Expiration Date with respect to any
          Restricted Facility Portion for purposes of this Section 6.6, Buyer
          shall be entitled to rely on the books and records included in the
          Acquired Assets relating to the operations at Avezzano, and Buyer's
          good faith determination thereof shall be conclusive and binding.

          accordance with Section 6.28.
 
               (e)  Seller shall cause all bank Liens on the Acquired Assets in
          Italy arising with respect to the indebtedness described in item 1 of
          Exhibit J hereto (the "Avezzano Debt") to be fully released within six
          months from the Closing Date and in

          Closing Date, the Italian government fails to pay interest subsidies
          in respect of the Avezzano Debt when due or within any applicable
          grace periods, Buyer shall pay Seller or its designee, promptly on
          demand, (x) 50% of any additional interest Seller or any of its

   Section 39.    Section 6.25 of the Acquisition Agreement is amended by
adding the following language at the end thereof:

               (e)   Buyer hereby agrees to waive any claim that Buyer may
          have against Seller arising out of: (i) Seller's manufacture and sale
          of Low Density Flash, EPROM, Field Memory or PTEC products
          (collectively "Waived Products"), (ii) Seller's sale of products
          fabricated based upon Flash-type EPROM Wafers-in-Process originating
          in Seller's Avezzano facility on or before the Closing Date (including
          completed devices in inventory); and (iii) Seller's sale of 1 Meg and
          4 Meg DRAM devices in inventory as of the Closing Date, not to exceed
          350,000 devices total ("DRAM" in this subsection (iii) shall not
          include Field Memory), where such claim is based on a violation of the
          Covenant Not to Compete in Section 6.25 of this Agreement. To the
          extent the manufacture or sale of any product is permitted by the
          foregoing waiver (i.e., such product is a Waived Product; a Flash-type
          EPROM under subsection (ii) above; or a DRAM under subsection (iii)
          above), such product shall be deemed a Licensed Product under the
          Cross License Agreement attached as Exhibit C to this Agreement. This
          waiver shall apply without regard to the fabrication facility utilized
          by Seller in the manufacture of Waived Products, provided that Seller
          has an ownership interest either directly or through a wholly owned
          subsidiary in any such fabrication facility so utilized of fifty
          percent (50%) or more.

               (f)   Seller shall have the right to transfer to a third
          party the entirety of its manufacturing operations relating to any one
          of the Waived Products (whether or not equipment or facilities are
          included in such transfer), and in connection with such transfer
          Seller shall transfer or terminate its contractual commitments,
          relating to such Waived Products; and, without otherwise diminishing
          the provisions of Section 6.15, in the event of such transfer as to a
          Waived Product, Buyer grants to Seller the right to sublicense to such
          transferee Acquired Intellectual Property that is licensed to Seller
          pursuant to Section 6.15(b) and that is directly related to and used
          in the manufacturing of such Waived Product, the scope of such
          sublicense being strictly limited to the manufacturing of such Waived
          Product.

<PAGE>
 
               (g)   The waiver provided in this Section is personal to
          Seller, and in the event of such transfer, Buyer's waiver described
          herein shall terminate and shall subsequently be void as to such
          Waived Product. Nothing in the preceding sentence shall limit any
          sublicense rights granted in subsection (f) above.
 
               (h)   Except as expressly waived in this Section, the
          provisions of the Covenant not to Compete of Section 6.25 remain
          undiminished and in full force and effect. Seller agrees that Buyer's
          granting of the limited waiver and limited right to sublicense in this
          Section shall not be considered to or deemed to in any way establish
          any course of dealing between the parties; and further agrees that
          Buyer shall not in any way be obligated to grant any further waiver
          under the Covenant not to Compete or any further right to sublicense
          under Section 6.15(b) in the future.

               (i)   For purposes of this Section, the following definitions

                shall mean non volatile, reprogrammable memory devices in
                which the storage cells include a floating gate, and in which
                erasure of the storage cells is achieved through application
                of electrical current.

                      "Field Memory" shall mean an application specific DRAM-
                based memory product specifically designed for use in consumer

     Micron Technology, Inc., a corporation duly organized and existing under
the laws of Delaware (herein called the "Company," which term includes any
successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to ________________, or registered assigns, the
principal sum of ___________________ Dollars on October 1, 2005 and to pay
interest thereon from September 30, 1998 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, semi-annually
on April 1 and October 1 in each year, commencing April 1, 1999, at the rate of
6-1/2% per annum, until the principal hereof is paid or made available for
payment. The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the March 15 or September 15 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date, subject to
the right of the Company to defer interest during an Extension Period. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

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

                                       3
<PAGE>
 
securities (including capital stock) that rank pari passu with or junior to
the securities on which such dividend, redemption, interest, principal or
guarantee payment is being made, (b) purchases of the Company's Common Stock
related to the issuance of the Company's Common Stock under any of the
Company's benefit plans for its directors, officers or employees, (c) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one series or class of the Company's capital stock for another
series or class of the Company's capital stock, and (d) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged). Prior to the termination of any such Extension
Period, the Company may further extend such Extension Period; provided, that
                                                              --------  
such Extension Period together with all previous and further extensions
thereof may not exceed 4 consecutive semi-annual interest payment periods and
may not extend beyond the Stated Maturity of the Securities. Upon the
termination of any Extension Period and the payment of all amounts then due,
the Company may commence a new Extension Period, subject to the above
requirements. No interest during an Extension Period shall be due and payable
except at the end thereof. In the event that a Holder converts his or her
Security (or portion thereof) within a period of 10 Business Days of the
Stated Maturity of the Securities, such Holder will receive, in addition to
the shares of Common Stock issuable upon conversion of such Security (or
portion thereof) (including any cash paid for fractional shares as provided in
Section 1403 of the Indenture), any accrued and unpaid interest that has
accrued from the date of commencement of the Extension Period to the earlier
to occur of (i) the date of termination of the Extension Period or (ii) the
date of conversion. Any such payment shall be in lieu of the payment otherwise
required to be made at the end of the Extension Period to the Holder of this
Security in whose name this Security is registered at the close of business on
the Regular Record Date next preceding the payment date for such interest.

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

     Payment of the principal of (and premium, if any) and any interest on this
Security will be made at Corporate Trust Office of the Trustee in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
                                                --------  -------             
option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

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

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

                                       Authorized Officer

                         FORM OF REVERSE OF SECURITY

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"),  issued and to be issued in one or
more series under an Indenture, dated as of June 15, 1997 (herein called the
"Indenture," which term shall have the meaning assigned to it in such 
instrument), between the Company and Norwest Bank Minnesota, National
Association, as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), and reference is hereby made to the
Indenture and all indentures supplemental thereto for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Company, the Trustee, the holders of Senior Debt and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $740,000,000.

     The Securities will not be subject to redemption prior to October 3, 2000
and will be redeemable on and after such date at the option of the Company, in
whole or in part, upon not less than 20 nor more than 60 days notice to the
Holders, at the Redemption Prices (expressed as percen  tages of the principal
amount) set forth below; provided, however, that the Securities will not be
                         --------  -------                                 
redeemable following October 3, 2000 and before October 2, 2002 unless the
Closing Price Per Share of the Company's Common Stock is at least 130% of the
Conversion Price for at least 20 

                                       5
<PAGE>
 
Trading Days within a period of 30 consecutive Trading Days ending within five
Trading Days of the call for redemption.

     The Redemption Price (expressed as a percentage of principal amount) is as
follows for the twelve-month periods beginning on October 1 of the following
years (beginning on October 3, 2000, and ending on September 30, 2001, in the
case of the first such period):

        Year                                    Redemption Price
        ----                                    ----------------
        2000.......................                  104.64%
        2001.......................                  103.71%
        2002.......................                  102.79%
        2003.......................                  101.86%
        2004.......................                  100.93%

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

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

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

                                       6
<PAGE>
 
deemed to include reference to the Repurchase Price only to the extent the
Repurchase Price is payable in cash.

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

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

     Subject to the provisions of the Indenture, the Holder of this Security is
entitled, at its option, at any time on or before October 1, 2005 (except that,
in case this Security or any portion hereof shall be called for redemption or
submitted for repurchase, such right shall terminate with respect to this
Security or portion hereof, as the case may be, so called for redemption or
submitted for repurchase, as the case may be, at the close of business on the
first Business Day next preceding the date fixed for redemption or repurchase,
as the case may be, as provided in the Indenture unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be), to
convert the principal amount of this Security (or any portion hereof which is
$1,000 or an integral multiple thereof) into fully paid and non-assessable
shares of the Common Stock of the Company, as said shares shall be constituted
at the date of conversion, at the Conversion Rate of 16.6667 shares of Common
Stock for each $1,000 principal amount of Securities, or at the adjusted
Conversion Rate in effect at the date of conversion determined as provided in
the Indenture, upon surrender of this Security, together with the conversion
notice hereon duly executed, to the Corporate Trust Office of the Trustee
accompanied (if so required by the Company) by instruments of transfer, in form
satisfactory to the Company and to the Trustee, duly executed by the Holder or
by its duly authorized attorney in writing. Such surrender (other than during an
Extension Period) shall, if made during any period beginning at the close of
business on a Regular Record Date and ending at the opening of business on the
Interest Payment Date next following such Regular Record Date (unless this
Security or the portion being converted shall have been called for redemption on
a Redemption Date during the period beginning at the close of business on a
Regular Record Date and ending at the opening of business on the first Business
Day after the next succeeding Interest Payment Date, or if such Interest Payment
Date is not a Business Day, the second such Business Day), also be accompanied
by payment in funds acceptable to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of this Security
then being converted. Subject to the aforesaid requirement for payment and, in
the case of a conversion after the Regular Record Date next preceding any
Interest Payment Date and on or before such Interest Payment Date, to the right
of the Holder of this Security (or any Predecessor Security) of record at such
Regular Record Date to receive an installment of interest (with certain
exceptions provided in the Indenture), no adjustment is to be made on conversion
for interest accrued hereon or for dividends on shares of Common Stock issued on
conversion.  If, during any Extension Period, this Security (or portion hereof)
called for 

                                       7
<PAGE>
 
redemption is surrendered for conversion, any accrued and unpaid interest on
this Security (or portion hereof) as of the Interest Payment Date occurring on
or immediately preceding the conversion date for this Security shall be paid
in cash to the Holder surrendering such Security for conversion. The Company
is not required to issue fractional shares upon any such conversion, but shall
make adjustment therefor as provided in the Indenture. The Conversion Rate is
subject to adjustment as provided in the Indenture. In addition, the Indenture
provides that in case of certain consolidations or mergers to which the
Company is a party or the sale of substantially all of the assets of the
Company, the Indenture shall be amended, without the consent of any Holders of
Securities, so that this Security, if then outstanding, will be convertible
thereafter, during the period this Security shall be convertible as specified
above, only into the kind and amount of securities, cash and other property
receivable upon the consolidation, merger or sale by a holder of the number of
shares of Common Stock into which this Security might have been converted
immediately prior to such consolidation, merger or sale (assuming such holder
of Common Stock failed to exercise any rights of election and received per
share the kind and amount received per share by a plurality of non-electing
shares). In the event of conversion of this Security in part only, a new
Security or Securities for the unconverted portion hereof shall be issued in
the name of the Holder hereof upon the cancellation hereof.

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

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

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The 

                                       8
<PAGE>
 
foregoing shall not apply to any suit instituted by the Holder of this
Security for the enforcement of any payment of principal hereof or any premium
or interest hereon on or after the respective due dates expressed herein.

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

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

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

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

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

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

                              ISSUANCE OF NOTES.

Section 101     Issuance of Notes; Principal Amount; Maturity.

     (a)  On September 30, 1998, the Company shall issue and deliver to the
Trustee, and the Trustee shall authenticate, Notes substantially in the form set
forth above, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by the Indenture
and this Supplemental Indenture, and with such letters, numbers, or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Notes, as
evidenced by their execution of such Notes.

     (b)  The Notes shall be issued in the aggregate principal amount of
$740,000,000 and shall mature on October 1, 2005.

Section 102     Interest on the Notes; Payment of Interest.

     (a)  The Notes shall bear interest at the rate of 6-1/2% per annum from
September 30, 1998.

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

     (c)  So long as no Event of Default under the Indenture has occurred and is
continuing, the Company shall have the right at any time during the term of the
Notes to defer interest payments from time to time by extending the interest
payment period for successive periods (each, an "Extension Period") not
exceeding 4 consecutive semi-annual interest payment periods for each such
period; provided, that no Extension Period may extend beyond the Stated Maturity
        --------                                                                
of the Notes.  At the end of each Extension Period, the Company shall be
responsible for the payment of, and the Company shall pay (subject to the
exception set forth in the last two sentences of this paragraph) to the Person
in whose name this Security is registered at the close of business on the
Regular Record Date next preceding such payment date all interest then accrued
and unpaid together with interest thereon compounded semi-annually at the rate
specified for the Notes to the extent permitted by applicable law; provided,
                                                                   -------- 
that during any Extension Period, the Company shall not, and shall not 

                                       13
<PAGE>
 
allow any of its Subsidiaries to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees of indebtedness for money borrowed) of the
Company that rank pari passu with or junior to the Notes (other than (a) any
dividend, redemption, liquidation, interest, principal or guarantee payment by
the Company where the payment is made by way of securities (including capital
stock) that rank pari passu with or junior to the securities on which such
dividend, redemption, interest, principal or guarantee payment is being made,
(b) purchases of the Company's Common Stock related to the issuance of the
Company's Common Stock under any of the Company's benefit plans for its
directors, officers or employees, (c) as a result of a reclassification of the
Company's capital stock or the exchange or conversion of one series or class of
the Company's capital stock for another series or class of the Company's capital
stock, and (d) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged).  Prior to the termination
of any such Extension Period, the Company may further extend such Extension
Period; provided, that such Extension Period together with all previous and
        --------                                                           
further extensions thereof may not exceed 4 consecutive semi-annual interest
payment periods and may not extend beyond the Stated Maturity of the Notes.
Upon the termination of any Extension Period and the payment of all amounts then
due, the Company may commence a new Extension Period, subject to the above
requirements.  No interest during an Extension Period shall be due and payable
except at the end thereof.  In the event that a Holder converts his or her Note
(or portion thereof) within a period of 10 Business Days of the Stated Maturity
of the Notes, such Holder will receive, in addition to the shares of Common
Stock issuable upon conversion of such Note (or portion thereof) (including any
cash paid for fractional shares as provided in Section 1403 of the Indenture),
any accrued and unpaid interest that has accrued from the date of commencement
of the Extension Period to the earlier to occur of (i) the date of termination
of the Extension Period or (ii) the date of conversion.  Any such payment shall
be in lieu of the payment otherwise required to be made at the end of the
Extension Period to the Holder of this Security in whose name this Security is
registered at the close of business on the Regular Record Date next preceding
the payment date for such interest.

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

     (d)  Payment of the principal of (and premium, if any) and any interest on
the Notes shall be made at the Corporate Trust Office of the Trustee in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address appears in the Security
Register.

                              CONVERSION OF NOTES

Section 501     Conversion Privilege and Conversion Rate.

     Subject to and upon compliance with the provisions of this Article, at the
option of the Holder thereof, any Note may be converted into fully paid and
nonassessable shares (calculated as to each conversion to the nearest 1/10,000
of a share) of Common Stock of the Company at the Conversion Rate, determined as
hereinafter provided, in effect at the time of conversion.  Such conversion
right shall commence immediately and expire at the close of business on October
1, 2005, subject, in the case of the conversion of any Global Security, to any
applicable book-entry procedures of the Depositary therefor.  In case a Note is
called for redemption at the election of the Company or the Holder thereof
exercises his right to require the Company to repurchase the Note, such
conversion right in respect of the Note shall expire at the close of business on
the Business Day next preceding the Redemption Date or the Repurchase Date (as
defined in Article Six), as the case may be, unless the Company defaults in
making the payment due upon redemption or repurchase, as the case may be (in
each case subject as aforesaid to any applicable book entry procedures).

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

     The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the "Conversion Rate") shall be initially 16.6667 shares of
Common Stock for each $1,000 principal amount of Notes.  The Conversion Rate
shall be adjusted in certain instances as provided in this Article Five.

Section 502     Adjustment of Conversion Rate.

     The rate at which shares of Common Stock shall be delivered upon conversion
(herein called the "Conversion Rate") shall be initially 16.6667 shares of
Common Stock for each $1,000 principal amount of Notes.  The Conversion Rate
shall be subject to adjustment from time to time as follows:

     (1)  In case the Company shall pay or make a dividend or other distribution
on Common Stock payable in shares of Common Stock, the Conversion Rate in effect
at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be increased by dividing such Conversion Rate by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, 

                                       17
<PAGE>
 
such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. If, after any such date
fixed for determination, any dividend or distribution is not in fact paid, the
Conversion Rate shall be immediately readjusted, effective as of the date the
Board of Directors determines not to pay such dividend or distribution, to the
Conversion Rate that would have been in effect if such determination date had
not been fixed. For the purposes of this paragraph (1), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

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

     (3)  In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Rate in effect at the
opening of business on the day following the day upon which such subdivision
becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of Common Stock shall each be combined into a smaller number
of shares of Common Stock, the Conversion Rate in effect at the opening of
business on the day following the day upon which such combination becomes
effective shall be propor tionately reduced, such increase or reduction, as the
case may be, to become effective immediately

                                       18
<PAGE>
 
after the opening of business on the day following the day upon which such
subdivision or combination becomes effective.

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

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

                                       19
<PAGE>
 
market price divided by (y) the number of shares of Common Stock outstanding on
such date for determination and (ii) the denominator of which shall be equal to
the current market price per share (determined as provided in paragraph (8) of
this Section 502) of the Common Stock on such date for determination.

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

     (7)  The reclassification of Common Stock into securities including other
than Common Stock (other than any reclassification upon a consolidation or
merger to which Section 1409 of the Indenture applies) shall be deemed to
involve (a) a distribution of such securities other than Common Stock to all
holders of Common Stock (and the effective date of such reclassification shall
be deemed to be "the date fixed for the determination of stockholders entitled
to receive such distribution" and "the date fixed for such determination" within
the meaning of paragraph (4) of this Section), and (b) a subdivision or
combination, as the case may be, of the number of shares of 

                                       20
<PAGE>
 
Common Stock outstanding immediately prior to such reclassification into the
number of shares of Common Stock outstanding immediately thereafter (and the
effective date of such reclassification shall be deemed to be "the day upon
which such subdivision becomes effective" or "the day upon which such
combination becomes effective", as the case may be, and "the day upon which such
subdivision or combination becomes effective" within the meaning of paragraph
(3) of this Section 502).

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

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

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

     (11) Notwithstanding the foregoing provisions of this Section, no
adjustment of the Conversion Rate shall be required to be made (a) upon the
issuance of shares of Common Stock pursuant to any present or future plan for
the reinvestment of dividends or (b) because of a tender or exchange offer of
the character described in Rule 13e-4(h)(5) under the Exchange Act or any
successor rule thereto.

     (12) To the extent permitted by applicable law, the Company from time to
time may increase the Conversion Rate by any amount for any period of time if
the period is at least twenty (20) days, the increase is irrevocable during such
period, and the Board of Directors shall have made a determination that such
increase would be in the best interests of the Company, which determination
shall be conclusive; provided, however, that no such increase shall be taken
                     --------  -------                                      
into account for purposes of determining whether the Closing Price Per Share of
the Common Stock exceeds the Conversion Price by 105% in connection with an
event which would otherwise be a 

                                       21
<PAGE>
 
Change of Control pursuant to Section 604(4). Whenever the Conversion Rate is
increased pursuant to the preceding sentence, the Company shall give notice of
the increase to the Holders in the manner provided in Section 106 of the
Indenture at least fifteen (15) days prior to the date the increased Conversion
Rate takes effect, and such notice shall state the increased Conversion Rate and
the period during which it will be in effect.


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

Section 601     Right to Require Repurchase.

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

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

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

     (1)  The shares of Common Stock deliverable in payment of the Repurchase
Price shall have a fair market value as of the Repurchase Date of not less than
the Repurchase Price.  For purposes of Section 601 and this Section 602, the
fair market value of shares of Common Stock shall be determined by the Company
and shall be equal to 95% of the average of the Closing Prices Per Share for the
five consecutive Trading Days immediately preceding the second Trading Day prior
to the Repurchase Date;

     (2)  The Repurchase Price shall be paid only in cash in the event any
shares of Common Stock to be issued upon repurchase of Notes hereunder (i)
require registration under any federal securities law before such shares may be
freely transferrable without being subject to any transfer restrictions under
the Securities Act upon repurchase and if such registration is not completed or
does not become effective prior to the Repurchase Date, and/or (ii) require
registration with or approval of any governmental authority under any state law
or any other federal law before such shares may be validly issued or delivered
upon repurchase and if such registration is not completed or does not become
effective or such approval is not obtained prior to the Repurchase Date;

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

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

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

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

     (1)  Unless the Company shall have theretofore called for redemption all of
the Outstanding Notes, on or before the 30th day after the occurrence of a
Change in Control, the Company or, at the request and expense of the Company on
or before the 15th day after such occurrence, the Trustee, shall give to all
Holders of Notes, in the manner provided in Section 106 of the Indenture, notice
(the "Company Notice") of the occurrence of the Change in Control and of the
repurchase right set forth herein arising as a result thereof.  The Company
shall also deliver a copy of such notice of a repurchase right to the Trustee.

                                       23
<PAGE>
 
     Each notice of a repurchase right shall state:

            (i)  the Repurchase Date,

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

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

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

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

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

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

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

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

     (2)  To exercise a repurchase right, a Holder shall deliver to the Trustee
on or before the 30th day after the date of the Company Notice (i) written
notice of the Holder's exercise of such right, which notice shall set forth the
name of the Holder, the principal amount of the Notes to be repurchased (and, if
any Note is to repurchased in part, the serial number thereof, the portion of
the principal amount thereof to be repurchased and the name of the Person in
which the portion thereof to remain Outstanding after such repurchase is to be
registered) and a statement that an election to exercise the repurchase right is
being made thereby, and, in the event that the Repurchase Price shall be paid in
shares of Common Stock, the name or names (with addresses) in which the
certificate or certificates for shares of Common Stock shall be issued, and (ii)
the Notes with respect to which the repurchase right is being exercised.  Such
written notice shall be irrevocable, except that the right of the Holder to
convert the Notes with respect to which the repurchase right is being exercised
shall continue until the close of business on the Business Day prior to the
Repurchase Date.

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

     (4)  If any Note (or portion thereof) surrendered for repurchase shall not
be so paid on the Repurchase Date, the principal amount of such Note (or portion
thereof, as the case may be) shall, until paid, bear interest to the extent
permitted by applicable law from the Repurchase Date at the rate of 6-1/2% per
annum, and each Note shall remain convertible into Common Stock until the
principal of such Note (or portion thereof, as the case may be) shall have been
paid or duly provided for.

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

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

     (7)  No fractions of shares shall be issued upon repurchase of Notes.  If
more than one Note shall be repurchased from the same Holder and the Repurchase
Price shall be payable in shares of Common Stock, the number of full shares
which shall be issuable upon such repurchase shall be computed on the basis of
the aggregate principal amount of the Notes so repurchased. Instead of any
fractional share of Common Stock which would otherwise be issuable on the
repurchase of any Note or Notes, the Company will deliver to the applicable
Holder a check for the current market value of such fractional share.  The
current market value of a fraction of a share is determined by multiplying 

                                       25
<PAGE>
 
the current market price of a full share by the fraction, and rounding the
result to the nearest cent. For purposes of this Section, the current market
price of a share of Common Stock is the Closing Price Per Share of the Common
Stock on the Trading Day immediately preceding the Repurchase Date.

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

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

merger (x) which does not result in any reclassification, conversion, exchange
or cancellation of outstanding shares of capital stock of the Company or (y)
which is effected solely to change the jurisdiction of incorporation of the
Company and results in a reclassification, conversion or exchange of outstanding
shares of Common Stock into solely shares of common stock); 

provided, however, that a Change in Control shall not be deemed to have occurred
- --------  -------
if either (a) the Closing Price Per Share of the Common Stock for any five
Trading Days within the period of 10 consecutive Trading Days ending immediately

above) or the period of 10 consecutive Trading Days ending immediately before
the Change in Control (in the case of a Change in Control under clause
604(2)(ii) above) shall equal or exceed 105% of the Conversion Price of the

result into the right to receive shares of stock and other securities or
property or assets (including cash) which includes shares of Common Stock of the
Company or common stock of another Person that are, or upon issuance will be,
traded on a United States national securities exchange or approved for trading
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 Person
formed by such consolidation or resulting from such merger or combination or
which acquires the properties or assets (including cash) of the Company, as the
case may be, shall execute and deliver to the Trustee a supplemental indenture
(which shall comply with the Trust Indenture Act as in force at the date of
execution of such supplemental indenture) modifying the provisions of this
Supplemental Indenture relating to the right of Holders to cause the Company to
repurchase the Notes following a Change in Control,

September 30 beginning September 30, 1998. Payment of all amounts due under the
Notes shall be made by mail to the registered address of each Holder, or if such
Holder shall elect, by wire transfer to the account designated by such Holder of
immediately available funds; provided, however, that for any Holder to receive
                             --------  -------                                
its interest or 

                                      -4-
<PAGE>
 
principal payments by wire transfer, the Company must receive such Holder's
written bank wire transfer instructions by the record date (as defined below)
for such payment. The Person in whose name any Note is registered at the close
of business on the third business day prior to any interest or principal payment
date (the "record date") shall be entitled to receive the interest, if any,
payable on such interest payment date notwithstanding any transfer or exchange
of such Note subsequent to the record date and prior to such interest or
principal payment date.

          2.2  Optional Prepayments of Notes.  Subject to the provisions of
               -----------------------------                               
Section 6, the Company may, at its option, prepay all or, from time to time,
part of the principal amount of the Notes, without penalty or premium, together
with interest on the principal amount so prepaid accrued to (but not including)
the date fixed for such prepayment.

          2.3  Allocation of Payments and Prepayments.  Each payment or
               --------------------------------------                  
prepayment of principal of less than the entire unpaid principal amount of the
Notes shall be allocated (in units of $1,000) by the Company among the Holders
of the Notes at the time outstanding, in proportion, as nearly as practicable,
to the respective aggregate unpaid principal amount of the Notes (not
theretofore called for prepayment) then held by them, respectively, with
adjustments, to the extent practicable, to equalize for any prior payments or
prepayments not made in such proportion.

          2.4    Notice of Prepayment to Holders.  Not less than three (3) nor
                 -------------------------------                              
more than ten (10) days prior to the date fixed for each optional prepayment,
the Company shall give notice thereof to the registered Holders of the Notes,
specifying the date fixed for prepayment and the aggregate principal amount to
be prepaid on such date. Such notice shall also contain instructions for the
delivery of the Notes by the Holders to the Company.  Subject to the provisions
of Section 6, such notice shall be irrevocable.

          2.5    Legal Holidays.  In any case where any interest payment date or
                 --------------                                                 
maturity date is not a Business Day, then (notwithstanding any other provision
of the Notes), payment of interest or principal, as applicable, with respect to
the Notes need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the Interest Payment
Date or Maturity Date, as the case may be.

     3.   Certain Covenants of the Company.
          -------------------------------- 

          3.1  Existence.  The Company will do or cause to be done all things
               ---------                                                     
necessary to preserve and keep in full force and effect its existence, provided
that this Section 3.1 shall not apply to a consolidation or merger of the
Company with or into another Person in which the Company is not the surviving
Person or conveyance, transfer or lease of the properties and assets of the
Company substantially as an entirety to another Person provided that the
transferee Person expressly assumes the due and punctual payment of the
principal and interest on all of the Notes and the performance or observance of
every covenant set forth in the Notes on the part of the Company to be performed
or observed.

                                      -5-

               -------------------------                                        
used or useful in the conduct of its business to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as, and to the extent, in the judgment
of the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business and not disadvantageous in any material respect to the Holders.

          3.3  Payment of Taxes and Other Claims.  The Company will pay or
               ---------------------------------                          
discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or upon the income, profits or property of the Company,
and (b) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company; provided, however,
                                                             --------  ------- 
that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim (i) whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings or (ii) if the failure to pay or discharge would not have a material
adverse effect on the assets, business, operations, properties or condition
(financial or otherwise) of the Company and its subsidiaries, taken as a whole.

          3.4  144A Information.  For so long as any Notes remain outstanding,
               ----------------                                               
if the Company is not subject to Section 13 or 15(d) of the Securities Exchange
Act of 1934, the Company will furnish to Holders of Notes and to prospective
purchasers of such Notes designated by such Holders the information required to
be delivered pursuant to 144A(d)(4) under the Securities Act to permit
compliance with Rule 144A under the Securities Act in connection with resales of
Notes.

     4.   Events of Default; Acceleration.
          ------------------------------- 

          4.1  Events of Default. The occurrence of any of the following
               -----------------
events shall constitute an "Event of Default" with respect to the Notes:

               (a) the Company defaults in the payment of the principal of any
Note when the same becomes due and payable at maturity or otherwise (other than
a default in the payment of principal resulting from application of Section 6
hereof); or

               (b) the Company defaults in the payment of interest on any Note
(other than a failure to pay interest resulting from application of Section 6
hereof) for 30 days after the same becomes due and payable; or

               (c) the Company defaults in the performance of or breaches any
covenant or warranty of the Company in this Note (other than a covenant or
warranty a default in whose performance or whose breach is elsewhere in this
Section specifically dealt with), and continuance

                                      -6-
<PAGE>
 
of such default or breach for a period of 60 days after there has been given, by
registered or certified mail, to the Company by the Holders of at least 25% in
principal amount of the Notes at that time outstanding a written notice
specifying such default or breach and requiring it to be remedied and stating
that such notice is a "Notice of Default" hereunder;

               (d) any event or condition occurs which results in the
acceleration of the maturity of any indebtedness under any bond, debenture, note
or other evidence of indebtedness for money borrowed having an aggregate
principal amount in excess of $50,000,000 or the Company fails to pay any such
indebtedness at the final maturity thereof, and such indebtedness is not
discharged, or such acceleration is not rescinded or annulled, within a period
of 30 days after there has been given, by registered or certified mail, to the
Company by the Holders of at least 25% in principal amount of the Notes at that
time outstanding a written notice specifying such acceleration or failure to pay
and stating that such notice is a "Notice of Default" hereunder; provided,
                                                                 --------  
however, that if any such failure, default or acceleration shall thereafter
- ------- 
cease or be cured, waived, rescinded or annulled, then the Event of Default
hereunder by reason thereof shall be deemed likewise to have been thereupon
cured, notwithstanding any receipt by the Company of a Notice of Default with
respect thereto; or

               (e) the entry by a court having jurisdiction in the premises of
(A) a decree or order for relief in respect of the Company in an involuntary
case or proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or (B) a decree or order adjudging the
Company a bankrupt or insolvent, or approving as properly filed a petition
seeking reorganization, arrangement, adjustment or composition of or in respect
of the Company under any applicable Federal or State law, or appointing a
custodian, receiver, liquidator, assignee, trustee, sequestrator or other
similar official of the Company or of any substantial part of its property, or
ordering the winding up or liquidation of its affairs, and the continuance of
any such decree or order for relief or any such other decree or order unstayed
and in effect for a period of 90 consecutive days; or

               (f) the commencement by the Company of a voluntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or of any other case or proceeding to be
adjudicated a bankrupt or insolvent, or the consent by it to the entry of a
decree or order for relief in respect of the Company in an involuntary case or
proceeding under any applicable Federal or State bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or
insolvency case or proceeding against it, or the filing by it of a petition or
answer or consent seeking reorganization or relief under any applicable Federal
or State law, or the consent by it to the filing of such petition or to the
appointment of or taking possession by a custodian, receiver, liquidator,
assignee, trustee, sequestrator or other similar official of the Company or of
any substantial part of its property, or the making by it of an assignment for
the benefit of creditors, or the admission by it in writing of its inability to

          4.2  Acceleration.  In the event an Event of Default has occurred and
               ------------                                                    
is continuing, subject to the provisions of Section 6, the Holder or Holders of
25% or more in principal amount of the Notes at the time outstanding at its or
their option may, by written notice or notices to the Company, declare the Notes
due and payable, whereupon the same shall forthwith mature and become due and
payable together with interest accrued thereon, without presentment, demand,
protest or notice, all of which are hereby waived; provided, however, that such
acceleration shall be automatic without the necessity of any such notice in the
case of Events of Default under clause (e) or (f) above.

          4.3  Waiver of Past Defaults.  The Holders of not less than a majority
               -----------------------                                          
in principal amount of the outstanding Notes may on behalf of the Holders of the
Notes waive any past default thereunder and its consequences, except a default
in the payment of principal of or any interest on the Note.  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 all purposes; but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

          4.4  Rescission and Annulment.  At any time after a declaration of
               ------------------------                                     
acceleration with respect to the Notes has been made and before a judgment or
decree for payment of the money due has been obtained, the Holders of a majority
in principal amount of the outstanding Notes, by written notice to the Company,
may rescind and annul such declaration and its consequences if the Company has
paid all overdue interest on all Notes and the principal of any Notes which has
become due otherwise than by such declaration of acceleration and all Events of
Default with respect to the Notes, other than the non-payment of the principal
of Notes which have become due solely by such declaration of acceleration, have
been cured or waived as provided in Section 4.3.

     5.     Remedies.  Subject to the provisions of Section 6 hereof, upon the
            --------                                                          
acceleration of the amounts due under the Notes in accordance with Section 4 or
if such amounts remain unpaid after the maturity date of the Notes, any Holder
may proceed to protect and enforce any right, power or remedy granted to it
under applicable law.  If any Holder of any Note or holder of any other
indebtedness of the Company gives any notice or takes any other action in
respect of a claimed default, the Company will forthwith give written notice
thereof to all Holders of the Notes at the time outstanding describing the
notice or action and the nature of the claimed default.  No course of dealing
and no delay on the part of any Holder of any Note in exercising any right,
power or remedy will operate as a waiver thereof or otherwise prejudice such
Holder's rights, powers or remedies.  No right, power or remedy conferred hereby
is exclusive of any other right, power or remedy referred to herein or now or
hereafter available at law, in equity, by statute or otherwise.

      6.  Subordination of Notes.
          -----------------------

          6.1  Subordination.  The Company hereby agrees and each Holder by its
               -------------                                                   
acceptance of this Note agrees that the Subordinated Claims are and shall be
postponed, subordinated and junior in right of payment to the prior payment in
full of all Senior Debt on the terms and conditions herein set forth.

          6.2  Permitted Payments; Deferral of Payments.  So long as there shall
               ----------------------------------------                         
not have occurred and be continuing (i) a default in the payment of principal,
premium, if any, or interest (including a default under any repurchase or
redemption obligation) or other amounts with respect to any Senior Debt or (ii)
any other event of default which has been declared in writing, or is
automatically effective in the case of Bankruptcy, Insolvency or Liquidation
Proceedings, with respect to any Designated Senior Debt (as such event of
default is defined therein or in the instrument under which it is outstanding)
and of which the Holder has received a notice (a "Blockage Notice") from the
holders of such Designated Senior Debt (each of the events specified in clause
(i) or clause (ii), a "Senior Default"), the Company shall be permitted to make,
and each Holder to accept and receive, regularly scheduled payments of principal
and accrued interest under this Note and any prepayment of principal that the
Company has decided to make, as heretofore set forth. Notwithstanding any
provision to the contrary contained in this Note, the Company shall not make,
and no Holder shall demand, accept, receive or retain, any payment or
distribution of any kind or character, whether in cash, property, securities or
otherwise, on account or in respect of any Subordinated Claim after a Senior
Default has occurred or deferral of interest on any Convertible Notes for a
period of time (a "Deferral Period") in accordance with the terms thereof has
occurred.  Payments due under the Notes may be resumed (x) in the case of a
deferral of interest, after the end of a Deferral Period (such payment to resume
as set forth in the next paragraph of this Note), and (y) in the case of
defaults referred to in clauses (i) and (ii) above, upon the earlier of:

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

     (B) in the case of a default referred to in clause (ii) above, the date
which is 179 days after the Blockage Notice is received,

unless this Section 6.2 otherwise prohibits the payment at the time of such
payment (including, without limitation, as a result of a payment default with
respect to the applicable Senior Debt as a consequence of the acceleration of
the maturity thereof or otherwise).

     If a Deferral Period shall occur, interest payable on all of the Notes on
regular payment dates occurring during such Deferral Period shall be deferred
and the Company shall be responsible for the payment of, and the Company shall
pay to the Person in whose name this Note is registered at the close of business
on the record date immediately preceding the regular payment date hereunder next
occurring after the termination of the Deferral Period, all interest then
accrued and unpaid together with, to the extent permitted by law, interest
thereon (compounded semi-annually on regular payment dates) at the rate
specified for the Notes.  The foregoing provisions shall apply during 

                                      -9-
<PAGE>
 
successive Deferral Periods with respect to the 2004 Convertible Notes and the
2005 Convertible Notes. The Company shall provide to the Holders written notice
of the occurrence of any Deferral Period at the time notice thereof is given to
the trustee under the Indenture, provided that any failure to do so shall not
affect the deferral of interest payments which would occur pursuant to the terms
hereof.

          6.3  Prior Payment to Senior Debt Upon Acceleration.  In the event
               ----------------------------------------------               
that any Notes are declared due and payable before their stated maturity, then
and in such event the Holders of the Senior Debt outstanding at the time such
Notes so become due and payable shall be entitled to receive payment in full in
cash or other payment satisfactory to the Holders of Senior Debt of all amounts
due or to become due on or in respect of all Senior Debt before the Holders of
the Notes are entitled to receive any payment by the Company on account of any
Subordinated Claim.  If the payment of Notes is accelerated because of an Event
of Default, the Company shall promptly notify Holders of Senior Debt of the
acceleration.

               The provisions of this Section 6.3 shall not apply to any payment
with respect to which Section 6.4 would be applicable.

          6.4  Bankruptcy, Insolvency or Liquidation Proceedings.  In the event
               -------------------------------------------------               
of any Bankruptcy, Insolvency or Liquidation Proceeding:

               (a) Priority of Payment. All Senior Debt shall be paid in full in
                   -------------------    
cash (but excluding indemnification obligations which are then contingent and as
to which no payment is then due and no claim or demand has then been made)
before any Holder shall be entitled to receive any payment or distribution of
any kind or character, whether in cash, property, securities or otherwise, in
respect of this Note in such Bankruptcy, Insolvency or Liquidation Proceeding.

               (b) Payments and Distributions on Subordinated Claims. Each
                   -------------------------------------------------
holder of Senior Debt shall be entitled to receive any payment or distribution
of any kind or character, whether in cash, property, securities or otherwise
(including, without limitation, any such payment or distribution which may
become payable or deliverable by reason of the payment of any other claim
against the Company being subordinated to the payment of the Subordinated
Claims), that may become payable or deliverable to Holders on account or in
respect of any Subordinated Claim, for application to the payment of all Senior
Debt, until all holders of Senior Debt have received payment in full in cash of
all Senior Debt (but excluding indemnification obligations which are then
contingent and as to which no payment is then due and no claim or demand has
then been made).

               (c) Delivery and Application. All such payments and distributions
                   ------------------------
on account or in respect of Subordinated Claims shall be delivered by the
debtor, trustee, receiver, disbursing agent or other Person making such payment
or distribution in such Bankruptcy, Insolvency or Liquidation Proceeding
directly to the holders of Senior Debt. If such payment or distribution consists
of any property or securities other than cash, (i) such payment or distribution
shall not be deemed applied to the payment of Senior Debt at any adjudicated or
imputed value and 

                                      -10-
<PAGE>
 
(ii) such payment or distribution and all other and future non-cash payments and
distributions on account or in respect of Subordinated Claims shall be delivered
to and held by the holders of Senior Debt, until cash proceeds from such non-
cash payments and distributions have been received by the holders of Senior Debt
in an amount sufficient (with any other cash paid or distributed to them by or
on behalf of the Company) to pay, in full and in cash, all of the Senior Debt
(but excluding indemnification obligations which are then contingent and as to
which no payment is then due and no claim or demand has then been made).

               (d)  Proof of Claim.
                    -------------- 

                    (1) If any Holder fails to file a proof of claim or other
statement or demand in respect of its Subordinated Claims in such Bankruptcy,
Insolvency or Liquidation Proceeding prior to the 30th day preceding any bar
date or other deadline for filing a proof of claim or other such statement or
demand therein, or if any such proof of claim, statement or demand filed by any
Holder prior to such day is in any respect inadequate or insufficient (in the
good faith opinion of any holder of Senior Debt), then each holder of Senior
Debt shall have the right, but not the obligation, to execute and deliver (in
the name of such Holder or in its own name but on behalf of such Holder, as such
holder of Senior Debt may elect) and file in such Bankruptcy, Insolvency or
Liquidation Proceeding any proof of claim, statement or demand which such holder
of Senior Debt may determine to be required or appropriate in respect of such
Subordinated Claim.

                    (2) To the extent necessary or reasonably appropriate to
permit the holders of Senior Debt to exercise the right granted to them under
this Section 6.4(d), each Holder hereby constitutes and appoints each holder of
Senior Debt as its attorney-in-fact and agent, with full power of substitution
and delegation, to execute, deliver and file any such proof of claim, statement
or demand as herein provided, and the power of attorney granted herein (being
coupled with an interest) is and shall be in all respects irrevocable.

                    (3) No holder of Senior Debt shall, by executing, delivering
or filing any such proof of claim, statement or demand, become liable or
responsible in any respect for the legality, adequacy or sufficiency thereof.

                    (4) Each holder of Senior Debt filing any such proof of
claim, statement or demand shall deliver or mail a copy thereof to the Company
at least 10 days prior to filing such proof of claim, statement or demand, but
the failure to deliver or mail such copy shall not in any respect (i) impose any
liability on such holder or upon any other holder of Senior Debt or (ii)
destroy, affect or impair the subordination provided hereby or any right, power
or benefit hereby granted to any holder of Senior Debt. The Company shall,
promptly after its receipt thereof, deliver or mail a copy of such proof of
claim, statement or demand to each Holder.

          6.5  Enforcement Rights.  No Holder shall have any right to enforce
               ------------------                                            
any Subordinated Claim, institute or attempt to institute any Bankruptcy,
Insolvency or Liquidation Proceeding against the Company or otherwise to take
any action against the Company or the 

                                      -11-
<PAGE>
 
Company's property during any periods payments on or distributions in respect of
Subordinated Claims are prohibited under Section 6.2, 6.3 or 6.4 hereof.

          6.6  Turnover.  If and in each instance that any Holder receives any
               --------                                                       
payment or distribution of any kind or character, whether in cash, property,
securities or otherwise (including, without limitation, any such payment or
distribution which may become payable or deliverable by reason of the payment of
any other Claim against the Company being subordinated to the payment of any
Subordinated Claim) on account or in respect of any Subordinated Claim which
payment or distribution is prohibited by Section 6.2, 6.3 or 6.4, at any time
when any Senior Debt or any commitment to extend credit which would constitute
Senior Debt is outstanding, or at any time when payment of interest on any
Convertible Notes is deferred as aforesaid, then and in each such event:

               (a) Transfer and Delivery. Each Holder shall forthwith pay over,
                   ---------------------
transfer and deliver such payment or distribution to the holders of Senior Debt,
whether or not any Bankruptcy, Insolvency or Liquidation Proceeding is then
pending, until the holders of Senior Debt have received payment in full and in
cash of all outstanding Senior Debt (but excluding indemnification obligations
which are then contingent and as to which no payment is then due and no claim or
demand has then been made).

               (b) Held in Trust. Each Holder hereby agrees to hold in trust for
                   -------------
the holders of Senior Debt, in the identical form received (except for any
necessary endorsement to the holders of Senior Debt) and as trustee of an
express trust, all payments and distributions required to be paid over,
transferred and delivered pursuant to this Section 6.6.

          6.7  Subrogation.  Subject to the prior payment in full and cash of
               -----------                                                   
any and all Senior Debt (but excluding indemnification obligations which are
then contingent and as to which no payment is then due and no claim or demand
has then been made), each Holder shall be subrogated to the rights of the
holders of such Senior Debt to receive payments and distributions, whether in
cash, property, securities or otherwise, applicable to the Senior Debt until
such Holder's Subordinated Claim is paid in full.  For such purposes:

               (a) Postponement of Subrogation. No right of subrogation shall be
                   ---------------------------
available to or may be enforced by any Holder, unless and until the payment in
full and in cash of all outstanding Senior Debt (but excluding indemnification
obligations which are then contingent and as to which no payment is then due and
no claim or demand has then been made).

               (b) No Representation, Warranty or Responsibility. No holder of
                   ---------------------------------------------
any Senior Debt makes any representation or warranty, or shall otherwise have
any responsibility, as to whether any such right of subrogation is accorded or
available to any Holder or is enforceable by it in any particular circumstance.

               (c) No Duty; No Exoneration. No holder of any Senior Debt shall
                   -----------------------
have any duty to any Holder to ensure, perfect, protect, enforce or maintain any
right of subrogation that 

                                      -12-
<PAGE>
 
might otherwise be accorded or available to or enforceable by such Holder. The
subordination provided herein and the rights of the holders of Senior Debt
hereunder shall remain fully enforceable on the terms set forth herein,
regardless of any act, omission or circumstance (whether or not attributable to
any holder of any Senior Debt and whether or not wrongful) which does or might
in any manner or in any respect destroy, limit, reduce, affect or impair any
right of subrogation otherwise accorded or available to or enforceable by any
Holder. Each holder of any Senior Debt shall remain utterly free to take or fail
to take any and all actions in respect of any Senior Debt or any Person liable
therefor or any collateral security therefor (including, without limitation,
each and all of the acts, omissions and matters described in Section 6.8),
without exonerating Holders, even if any right of subrogation is destroyed,
limited, reduced, affected or impaired thereby.

               (d) Disallowed Senior Debt. The subordination provided herein and
                   ----------------------
the rights of the holders of Senior Debt hereunder shall be fully enforceable as
to all Senior Debt which is not allowed, allowable or enforceable in any
Bankruptcy, Insolvency or Liquidation Proceeding, even if and even though no
right of subrogation is available in respect of such Senior Debt.

               (e) Payment of Senior Debt. For purposes of enforcing any right
                   ----------------------
of subrogation on the terms set forth in this Section 6.7, no payment or
distribution on account of any Subordinated Claim arising in respect of this
Note applied to the payment of Senior Debt shall, as between the Company and
Holders and to the extent of the payment or distribution so applied, discharge
the liability of the Company for the payment of such Senior Debt and, to this
end, the Company shall remain obligated to pay such Senior Debt in full
notwithstanding any such application.

          6.8  Subordination Not Prejudiced, Affected or Impaired.  No right of
               --------------------------------------------------              
any present or future holder of any Senior Debt to enforce subordination as
provided in this Note shall at any time in any way be prejudiced, affected or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act on the part of any holder of Senior Debt or by any breach or
default by the Company in the performance or observance of any promise, covenant
or obligation enforceable by any Holder, regardless of any knowledge thereof
that any holder of Senior Debt may have or otherwise be charged with.

               (a) Certain Acts, Omissions and Events. Without in any way
                   ----------------------------------
limiting the generality of the foregoing, each holder of any Senior Debt may at
any time and from time to time, without the consent of or notice to Holder,
without incurring any responsibility or liability to any Holder and without in
any manner prejudicing, affecting or impairing the subordination provided herein
or the obligations of Holders to the holders of Senior Debt:

                   (1) Make loans and advances to the Company or issue, guaranty
or obtain letters of credit for the account of the Company or otherwise extend
credit to the Company, in any amount and on any terms, whether pursuant to a
commitment or as a discretionary advance and whether or not any default or event
of default or failure of condition is then continuing;

                                      -13-
<PAGE>
 
                   (2) Change the manner, place or terms of payment or extend
the time of payment of, or renew or alter, compromise, accelerate, extend or
refinance, any Senior Debt or any agreement, guaranty, lien or obligation of the
Company or any other Person in any manner related thereto, or otherwise amend,
supplement or change in any manner any Senior Debt or any such agreement,
guaranty, lien or obligation;

                   (3) Increase or reduce the amount of any Senior Debt or the
interest accruing thereon;

                   (4) Release or discharge any Senior Debt or any guaranty
thereof or any agreement or obligation of the Company or any other Person with
respect thereto;

                   (5) Take or fail to take any collateral security for any
Senior Debt or take or fail to take any action which may be necessary or
appropriate to ensure that any lien upon any property securing any Senior Debt
is duly enforceable or perfected or entitled to priority as against any other
lien or to ensure that any proceeds of any property subject to any lien are
applied to the payment of any Senior Debt;

                   (6) Release, discharge or permit the lapse of any or all
liens upon any property at any time securing any Senior Debt;

                   (7) Exercise or enforce, in any manner, order or sequence, or
fail to exercise or enforce, any right or remedy against the Company or any
collateral security or any other Person or property in respect of any Senior
Debt or lien securing any Senior Debt or any right under this Note; or

                   (8) Sell, exchange, release, foreclose upon or otherwise deal
with any property that may at any time be subject to any lien securing any
Senior Debt.

          (b) No Release or Exoneration. No exercise, delay in exercising or
              -------------------------
failure to exercise any right arising under this Section 6, no act or omission
of any holder of any Senior Debt in respect of the Company or any other Person
or any collateral security for any Senior Debt or any right arising under this
Section 6, no change, impairment, or suspension of any right or remedy of any
holder of any Senior Debt, and no other act, failure to act, circumstance,
occurrence or event which, but for this provision, would or could act as a
release or exoneration of the obligations of any Holder hereunder shall in any
way affect, decrease, diminish or impair any of the obligations of any Holder
under this Note or give any Holder or any other Person any recourse or defense
against any holder of Senior Debt in respect of any right arising under this
Section 6.

     6.9 Reinstatement. If any payment or distribution at any time made on
         -------------
account or in respect of any Senior Debt is thereafter rescinded, recovered, set
aside, avoided or required to be returned, then such Senior Debt and all rights
of the holder of such Senior Debt to enforce 

                                      -14-
<PAGE>
 
subordination as set forth herein shall be automatically and unconditionally
reinstated, as fully as if such payment or distribution had never been made.

     7.   Amendments and Waivers.  Neither this Note nor any term hereof may be
          ----------------------                                               
amended or waived orally or in writing, except that any term of the Notes may be
amended and the observance of any term of the Notes may be waived (either
generally or in a particular instance and either retroactively or
prospectively), and such amendment or waiver shall be applicable to all of the
Notes, upon the approval of the Company and the Holders of fifty percent (50%)
or more of the outstanding principal amount of all then outstanding Notes;
provided, however, that any amendment to (i) the outstanding principal amount of
- --------  -------                                                               
the Notes, (ii) the rate of interest borne by the Notes, (iii) the date of
maturity or interest payment dates of the Notes or (iv) this Section 7 shall
require the approval of the Holder of each Note to which such amendment shall
apply. The Company will not amend any provision of any other Note in a manner
favorable to any Holder thereof unless a similar amendment is made or offered
with respect to all of the Notes.  Each Holder of this Note by its acceptance
hereof acknowledges and agrees that the subordination provisions of this
instrument are for the benefit of the holders of the Senior Debt and that,
accordingly, no provision of Section 6 hereof may be amended or otherwise
modified without the prior written consent of each holder of Senior Debt at such
time outstanding.

Securities Act, or the securities laws of any state or other jurisdiction.
Neither this Note nor any interest or participation herein may be reoffered,

buyer" as defined in Rule 144A.

     10. Transfer Agent and Registrar; Transfers of Notes.
         -------------------------------------------------

         10.1  Company Own Transfer Agent and Note Registrar.  The Company shall
               ---------------------------------------------                    
serve as its own agent for the transfer and exchange of Notes and registrar to
keep a register or registers in which, subject to such reasonable regulations as
it may prescribe, the Company will provide for the registration of Notes and the
registration of transfers of Notes (the "Note Register").  The Note Register
will be maintained at the office of the Company set forth in Section 8 hereof.

         10.2  Transfer of Notes.  Upon presentation of any Note for
               -----------------                                    
registration of transfer at the office of the Company set forth in Section 8
hereof accompanied by (i) certification by the transferor that such transfer is

in a form approved by the Company executed by the registered Holder, in person
or by such holder's attorney thereunto duly authorized in writing, and including
the name, address and telephone and fax numbers of the transferee and name of
the contact person of the transferee, such Note shall be transferred on the Note
Register, and a new Note of like tenor and bearing the same legends shall be
issued in the name of the transferee and sent to the transferee at the address
and c/o the contact person so indicated.  Transfers and exchanges of Notes shall
be subject to such additional restrictions as are set forth in the legends on

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

         10.3  Registered Holders Treated as Absolute Owners.  The Company may
               ---------------------------------------------                  
deem and treat the Person in whose name any Note is registered on the Note
Register as the absolute owner of such Note (whether or not such Note shall be
overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of and,
subject to the provisions of this Agreement, interest on such Note and for all
other purposes; and neither the Company nor any agent of the Company shall be
affected by any notice to the contrary.  All such payments so made to any such
Person, or upon such Person's order, shall 

                                      -16-

         ----------------------                                        
represents and warrants as follows:

         11.1 Qualified Institutional Buyer.  Such Holder is a "qualified
              -----------------------------                              
institutional buyer" as such term is defined in Rule 144A under the Securities
Act.  Such Holder has been advised that this Note has not been registered under
the Securities Act, or any state securities laws and, therefore, cannot be
resold unless it is registered under the Securities Act and applicable state
securities laws or unless an exemption from such registration requirements is
available.  Such Holder is aware that the Company is under no obligation to
effect any such registration or to file for or comply with any exemption from
registration. Such Holder has not been formed solely for the purpose of making
this investment and is acquiring the Note for its own account, or for the
account of a qualified institutional buyer to whom notice is given that the
transfer is being made in reliance on Rule 144A, for investment, and not with a
view to, or for resale in connection with, the distribution thereof.

         11.2  Access to Information.  The initial Holder of this Note
               ---------------------                                  
acknowledges that the Company has given such Holder access to the corporate
records and accounts of the Company and to all information in its possession
relating to the Company, has made its officers and representatives available for
interview by such Holder, and has furnished such Holder with all documents and
other information required for such Holder to make an informed decision with
respect to the acquisition of the Note.
