                               Text of Amendments

Explanatory Note:

         Each of the above listed Items is hereby amended by deleting the Item
in its entirety and replacing it with the Items included herein.

         The purpose of the amendment is to make certain changes to Management's
Discussion and Analysis of Financial Condition and Results of Operations (Item
7) and to the notes to the financial statements included in the Financial
Statements and Supplementary Data (Item 8), which were incorporated by reference
into Part II of the Annual Report on Form 10-K for the year ended December 31,
1998 of Texas Instruments Incorporated (the "company" or "TI") that was filed on
February 22, 1999 (the "Original Filing"), and to the Exhibits, Financial
Statement Schedules and Reports on Form 8-K (Item 14) of Part IV of the Original
Filing.

         The amendment is being made to reflect certain comments received by TI
from the Securities and Exchange Commission (the "SEC"). The SEC requested that
TI amend the Original Filing to, among other things, (i) reorder its
Management's Discussion and Analysis of Financial Condition and Results of
Operations in order to place the discussion of inclusive results ahead of
results without special charges and gains, (ii) provide additional disclosures,
in notes to its financial statements, Management's Discussion and Analysis of
Financial Condition and Results of Operations and quarterly financial data,
regarding certain special charges taken by TI, and (iii) restate results of
operations to reflect the shift of $14 million of pretax manufacturing costs
from second quarter to third quarter of 1998. This restatement had no impact on
the company's revenues or earnings for the year.

         Any items in the Original Filing not expressly changed hereby shall be
as set forth in the Original Filing. All information contained in this amendment
and the Original Filing is subject to updating and supplementing as provided in
the company's periodic reports filed with the SEC subsequent to the date of such
reports.

ITEM 7: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

         Note: Throughout this report, TI total financial results are reported
with the memory business. Semiconductor results are reported without memory. The
memory business was divested in the third quarter of 1998.

1998 RESULTS OF OPERATIONS COMPARED WITH 1997

         TI revenues for 1998 were $8460 million, down 13 percent from 1997, due
primarily to lower prices in dynamic random access memories (DRAMs), and to a
lesser extent, to the absence of revenue due to the sale of the memory business.
Operating margin was 4.7 percent, down from 6.3 percent in 1997, primarily due
to lower DRAM prices, and to a lesser extent due about equally to the special
charges associated with a worldwide restructuring of support functions and
consolidation of manufacturing operations, and with the discontinuance of the
memory-chip manufacturing joint venture with Hitachi, Ltd. Earnings per share
were $1.02, compared with $0.76 for 1997.

         Other income for 1998 was $293 million, up $101 million from 1997
primarily due to an $83 million gain in 1998 on the sale of TI's shares in the
TI-Acer joint venture to Acer Corporation. This was insufficient to offset the
decline in operating margin, resulting in income before taxes of $617 million,
down $96 million from 1997. TI orders were $8069 million for 1998, compared with
$9796 million in 1997, primarily due to declines in memory orders.

         While income before taxes declined, income after taxes for the year was
$407 million, up 35 percent from $302 million in 1997, due to the absence of the
1997 non-deductible acquisition-related R&D charge.

         During the fourth quarter, TI essentially completed the restructuring
announced in June of 1998. Annualized cost savings for the company are estimated
to be $270 million.

         The results for the fourth quarter include special charges of $72
million, substantially all of which was related to the closing of an
assembly/test joint venture with Samsung Electronica, Lda. in Portugal and the
sale of the Aversa, Italy plant. Of the $72 million, $35 million was for
severance, $35 million for other cash-related costs and $2 million for asset
write-downs. Of the latter $35 million charge, $20 million was a cash payment
required as part of an agreement with the third-party buyer of a materials &
controls manufacturing operation in Europe. The balance was for
previously-received government grants expected to be repaid as a result of the
closing of the European semiconductor assembly operation. The year-ago quarter
had a charge of $461 million for in-process R&D associated with the acquisition
of Amati Communications Corporation, along with a pretax charge of $42 million
for cost-reduction actions, primarily for severance in the materials & controls
business.

         In addition to the fourth-quarter charges, 1998 earnings include
special charges of $477 million, of which $219 million was cash payments for
discontinuing the memory-chip manufacturing joint venture with Hitachi, Ltd.,
$25 million was for purchased in-process R&D and $233 million was for a
worldwide


                                       3
<PAGE>   4


restructuring of support functions and consolidation of manufacturing
operations. Of the $233 million, $161 million was for severance, $55 million for
asset write-downs, including accelerated depreciation on fixed assets phased out
during 1998, and $17 million for vendor cancellation and lease charges. There
was also an $83 million pretax gain in the year on the sale of TI's shares in
the TI-Acer joint venture to Acer Corporation. In 1997, special pretax charges,
in addition to those in the fourth quarter, were $100 million, primarily related
to the sale of TI's mobile computing business and the termination of
joint-venture agreements in Thailand. There also was a $66 million special
pretax gain for the sale of three businesses, the largest of which was software.

         Excluding the effect of the special items for 1998, operating margin
for the year was 10.9 percent, income was $719 million and earnings per share
were $1.79. TI believes that, for analytical purposes, the effect of these items
should be excluded from operating results because they are not necessarily
indicative of future operating results or of future financial condition.
Additional information relating to these items appears below under the heading
"Special Charges and Gains."

         SEMICONDUCTOR: For 1998, semiconductor revenues and operating margin
were down slightly, and orders were down modestly, due to overall semiconductor
market weakness.

         For the year, DSP revenues increased 29 percent to a record level,
driven by wireless. Analog revenues declined 4 percent for the year, as strength
in wireless was insufficient to offset weakness in other markets, particularly
hard disk drive (HDD). Collectively, TI's remaining semiconductor product areas
saw revenues down moderately from 1997, primarily due to overall semiconductor
market weakness.

         In the fourth quarter, DSP and analog comprised 59 percent of TI's
semiconductor revenues. TI expects modest sequential revenue growth in its
semiconductor business in the first quarter of 1999, leading to moderate growth
for the year, based on continuing strength in wireless and ongoing improvements
in HDD and the mass markets. The HDD market represents a growing opportunity for
TI, due to its market leadership and extensive portfolio across the primary HDD
integrated circuits (application-specific integrated circuits (ASICs), read
channels, pre-amps, and servo control).

         TI expects that 1999 earnings will reflect continued improvement in
semiconductor markets and the ongoing benefit of TI's strategic positioning, as
well as the cost reductions realized from completion of restructuring actions.
In the first quarter, these improvements may be largely offset by the transition
to increased profit sharing, as the company moves to higher operating margins.
Profit-sharing expenses are accrued quarterly, based on the company's full-year
estimated operating profit margin.

         MATERIALS & CONTROLS (M&C): For the full year, M&C revenues were down 1
percent due to weak Asian markets. Operating margin was up for the year to 15.0
percent, reflecting gains from the best-cost producer strategy. During 1998,
plant closings took place in Canada and Michigan, restructuring and early
retirements took place in Holland and Japan, and the Aversa, Italy plant was
sold.


                                       4
<PAGE>   5


         EDUCATIONAL & PRODUCTIVITY SOLUTIONS (E&PS): For the year, the E&PS
business showed a rise in operating margin of 3.4 percentage points to 16.6
percent, as a result of cost improvements.

         DIGITAL IMAGING: For 1998, the operation reduced its loss to one-half
of the 1997 level and continues to make progress on product positioning and
operational performance.

         DIVESTED ACTIVITIES: For 1998, memory revenues were down 60 percent and
orders were down 62 percent from 1997 levels, primarily due to lower DRAM
prices, with the balance due to the divestiture of the memory business in the
third quarter of 1998. Loss from memory operations was $498 million, versus a
loss of $192 million in 1997.

         FINANCIAL CONDITION: During 1998, cash and cash equivalents plus
short-term investments decreased by $771 million to $2249 million. The
discontinuance of the joint venture with Hitachi and the acquisition of those
operating assets (which were subsequently included in the sale of the memory
business) required approximately $300 million of cash in the first quarter. In
addition, $91 million of cash was used to purchase the remaining outstanding
shares of Amati Communications Corporation's common stock in the first quarter.
Under the terms of the sale of TI's memory business to Micron Technology, TI
provided $550 million of cash financing to Micron in the third quarter. At
closing, TI deferred an estimated pretax gain of $127 million on the sale until
the recovery of the TI-provided financing. In the fourth quarter, TI made an
additional $130 million payment to Micron as part of the contractually required
working capital.

         In the memory transaction, TI received approximately 28.9 million
shares of Micron common stock, $740 million face value of a 6.5 percent
convertible note and $210 million face value of a 6.5 percent subordinated note.
These securities were originally valued at $1717 million. At year-end, market
value was $2441 million. Market value changes, net of tax, are recorded as an
adjustment to stockholders' equity.

         Approximately $300 million of grants from the Italian government to
TI's former memory operations in Italy are being reviewed in the ordinary course
by government auditors. TI understands that these auditors are questioning
whether some of the grants were applied to purposes outside the scope of the
grants. TI's deferred gain on the sale of its memory business may be reduced to
the extent that any grants are determined to have been misapplied. Also, TI
understands that an Italian prosecutor is conducting a criminal investigation
concerning a portion of the grants relating to specified research and
development activities. TI believes that the grants were obtained and used in
compliance with applicable law and contractual obligations.

         Cash flow from operating activities net of additions to property, plant
and equipment was $220 million in 1998.

         Capital expenditures totaled $1031 million for 1998 versus $1238
million for 1997. Depreciation was $1169 million for 1998 compared to $1109
million for 1997. Authorizations for future capital expenditures were $541
million at December 31, 1998. TI's capital expenditures for 1999 are forecast to
be level with 1998 at $1.0 billion. Depreciation for 1999 is expected to be $1.0
billion. R&D is expected to be $1.1 billion, versus $1.2 billion in 1998.


                                       5

         The company maintains lines of credit to support commercial paper
borrowings and to provide additional liquidity. These lines of credit totaled
$669 million at December 31, 1998. Of this amount, $600 million exists to
support commercial paper borrowings or short-term bank loans.

         During 1998, TI repurchased approximately 4.5 million shares of common
stock, at a cost of $294 million, as a part of its previously stated intent to
neutralize the potential dilutive effect of shares to be issued under employee
stock options.

         At the end of 1998, the debt-to-total-capital ratio was .17, compared
to the 1997 year-end value of .19.

         As previously announced, the timing of TI dividend declarations in 1998
was moved, effective March 1998, from the third month of a quarter to the first
month of the following quarter. As a result of this one-time lag, 1998 contains
three rather than four dividend declarations.

         YEAR 2000: Since 1995, TI has been actively engaged in addressing Year
2000 (Y2K) issues. These result from the use of two-digit, rather than
four-digit, year dates in software, a practice which could cause date-sensitive
systems to malfunction or fail because they may not recognize or process date
information correctly.

         State of Readiness: To manage its Y2K program, TI has divided its
efforts into four program areas:

         Information Technology (computer hardware, software and electronic data
            interchange (EDI) interfaces);

         Physical Plant (manufacturing equipment and facilities);

         Products (including product development); and

         Extended Enterprise (suppliers and customers).

         For each of these program areas, TI is using a four-step approach:

         Ownership (creating awareness, assigning tasks);

         Inventory (listing items to be assessed for Y2K readiness);

         Assessment (prioritizing the inventoried items, assessing their Y2K
            readiness, planning corrective actions, making initial contingency
            plans); and

         Corrective Action Deployment (implementing corrective actions,
            verifying implementation, finalizing contingency plans).

         At December 31, 1998, the Ownership, Inventory, and Assessment steps
were essentially complete for priority items in Information Technology, Physical
Plant and Products. TI's assessment activities for Extended Enterprise will
continue into 1999. TI considers priority items to be those that could
significantly disrupt TI's business operations. The target completion date for
priority items for the remaining step (Corrective Action Deployment) is June
1999 for all program areas.


                                       6
<PAGE>   7


         As of December 31, 1998, the status for each program area is as
follows:

         INFORMATION TECHNOLOGY: Corrective actions have been deployed for
substantially all of TI's legacy business strategic information systems
(manufacturing, marketing, financial and human resources). In the ordinary
course of business, TI continues to install new business systems as appropriate.
Verification of Year 2000 readiness is incorporated into the process of
implementing these new systems. Assessment of infrastructure hardware and
software that support TI's enterprise-wide networks and servers is essentially
complete, and deployment of corrective actions is under way. TI has also
deployed an assessment tool and corrective action process for desktop computers.
The readiness of TI's EDI interfaces has been assessed, and testing continues
with major customers and suppliers.

         PHYSICAL PLANT: Assessment of manufacturing equipment and facilities is
substantially complete and corrective actions are under way.

         PRODUCTS: TI is essentially complete with the Year 2000 readiness
assessment of its products and is providing product status information on its
company web site. Divested product lines are not part of the assessment. This
effort includes semiconductor devices sold within the past five years. TI's
assessment indicates that the majority of semiconductor products either have no
date logic or are programmable devices that require customer assessment of any
software and firmware or other elements added by or at the request of TI's
customers. TI has identified date-related issues with certain of TI's
semiconductor application software development tools and is providing corrective
software patches. The company believes these development tool issues are
unlikely to cause significant problems for TI customers. Assessment of products
of the materials & controls and educational & productivity solutions businesses
indicates they are either Year 2000 ready or have no date logic.

         EXTENDED ENTERPRISE: TI's Y2K supplier program attempts to assess the
readiness of TI suppliers, focusing on those that could significantly disrupt
TI's business operations. TI began contacting its suppliers in 1997 to assess
their readiness. This effort is ongoing and is expected to be complete by June
1999. TI intends to finalize contingency plans by June 1999 on the basis of
information gathered through the assessment process. TI continues to discuss Y2K
status with selected strategic customers.

         COSTS TO ADDRESS Y2K ISSUES: TI's estimated aggregate costs for its Y2K
activities from 1995 through 2000 are expected to range from $70 million to $90
million. Through December 31, 1998, TI has spent approximately $53 million.

         RISKS OF Y2K ISSUES AND CONTINGENCY PLANS: TI continues to review Year
2000 issues relating to its information technology, physical plant, products,
suppliers and customers, as well as legal risks that may be associated with
discontinued products and divested product lines. TI's contingency planning
process is intended to mitigate worst-case business disruptions. The company is
preparing contingency plans to address worst-case issues such as delays in
delivery of product. As noted above, the company expects its contingency plans
to be complete by June 1999.

         MARKET RISK SENSITIVE INSTRUMENTS: The U.S. dollar is the functional
currency for financial reporting. In this regard, the company uses forward
currency exchange contracts,


                                       7
<PAGE>   8


including lira note currency swaps, to minimize the adverse earnings impact from
the effect of exchange rate fluctuations on the company's non-U.S. dollar net
balance sheet exposures. For example, at year-end 1998, the company had forward
currency exchange contracts outstanding of $756 million (including $161 million
to sell yen, $132 million to buy lira and $105 million to buy deutsche marks).
Similar hedging activities existed at year-end 1997. Because most of the
aggregate non-U.S. dollar balance sheet exposure is hedged by these exchange
contracts and swaps, a hypothetical 10% plus or minus fluctuation in non-U.S.
currency exchange rates would not be expected to have a material earnings
impact, e.g., based on year-end 1998 balances and rates, a pretax currency
exchange gain or loss of $6 million.

         The company has interest rate swaps that change the characteristics of
the interest payments on its $300 million of 6.125% notes due 2006 from
fixed-rate payments to short-term LIBOR-based variable rate payments in order to
achieve a mix of interest rates on the company's long-term debt which, over
time, is expected to moderate financing costs. The effect of these interest rate
swaps was to reduce interest expense by $3 million in 1998. The year-end 1998
effective interest rate for the $300 million of notes due 2006, including the
effect of the swaps, was approximately 4.6% (5.1% at year-end 1997). These swaps
are sensitive to interest rate changes. For example, if short-term interest
rates increase (decrease) by one percentage point from year-end 1998 rates,
annual pretax interest expense would increase (decrease) by $3 million.

         The company's long-term debt has a fair value, based on current
interest rates, of approximately $1346 million at year-end 1998 ($1390 million
at year-end 1997). Fair value will vary as interest rates change. The following
table presents the aggregate maturities and historical cost amounts of the debt
principal and related weighted-average interest rates by maturity dates at
year-end 1998:

aggregate fair value and carrying amount was $1771 million at year-end 1998
($2566 million at year-end 1997). Fair value will vary as interest rates change.
The following table presents the aggregate maturities of cash equivalents and
short-term investments and related weighted-average interest rates by maturity
dates at year-end 1998:

         The company's investments at year-end 1998 consisted of the following
(amounts at year-end 1997 were not material):

         o     Equity investments - primarily 28,933,092 Micron common shares
               acquired in 1998, along with several other publicly traded
               investments.

         o     Debt investments - 6.5% Micron convertible and subordinated notes
               acquired in 1998. The convertible note (convertible into
               12,333,358 Micron common shares at $60 per share) and the
               subordinated note have face amounts of $740 million and $210
               million. The notes, which mature 2005, have a weighted-average
               imputed interest rate of 8.7%.

         o     TI Ventures - an externally managed venture fund that invests in
               the development of new markets. As of year-end 1998, it had
               invested in 14 companies focused on next-generation applications
               of digital signal processors.

         o     Other investments - consist of mutual funds that are acquired to
               generate returns that offset changes in certain liabilities
               related to deferred compensation arrangements. The mutual funds
               hold a variety of debt and equity investments.

         The equity investments (fair value of $1516 million) and venture fund
(fair value of $37 million) are sensitive to equity price changes. For example,
if prices of the equity investments increase or decrease 10%, the company would
record an increase or decrease in stockholders' equity of $152 million.
Similarly, if prices for the venture fund increase or decrease 10%, the company
would record an increase or decrease in other income (expense) of $4 million.
Changes in prices of the other investments are expected to offset related
changes in deferred compensation liabilities such that a 10% increase or
decrease in investment prices would not affect operating results.

         Fair value of the debt investments ($978 million) will vary as interest
rates change (and also for the convertible note, as the underlying equity share
price changes). The following table presents the aggregate historical cost
maturities of debt investments and related weighted-average interest rates by
maturity dates:

         TI's orders in 1997 were $9796 million, compared with $9268 million in
1996. Net revenues in 1997 were $9750 million, compared with $9940 million in
1996. Financial results in 1997 and 1996 included revenues from TI businesses
that have been sold, primarily memory, software, mobile computing and printers.

         Net income for 1997 was $1805 million, which consisted of income from
continuing operations of $302 million, income from the discontinued defense
business of $52 million, gain on the sale of the discontinued defense business
of $1473 million, and an extraordinary charge of $22 million associated with
debt retirement. On a similar basis, net income for 1996 was $63 million, which
consisted of a loss from continuing operations of $46 million and income from
the discontinued defense business of $109 million. Earnings per share were $0.76
for 1997, compared with a loss of $0.12 in 1996.

         Profit from operations in 1997 was $615 million, versus a loss of $26
million in 1996. The improvement was primarily due to higher semiconductor
profits, and to a lesser degree, due to the absence of losses from the sold
businesses, primarily memory, software and mobile computing. In 1996, these sold
businesses lost $229 million more than in 1997.

         Results for the fourth quarter include a charge of $461 million for
in-process R&D associated with the acquisition of Amati Communications
Corporation, along with a pretax charge of $42 million for cost reduction
actions, primarily in the materials & controls business. In addition to the
fourth-quarter charges, the 1997 earnings include previously announced special
pretax charges of $56 million, primarily related to the sale of TI's mobile
computing business, and $44 million for the termination of joint-venture
agreements in Thailand.

         Results for 1997 also include a $66 million gain for the sale of three
businesses, the largest of which was software. The total of the 1997 special
items is equivalent to $1.27 per share. In 1996, special charges were $400
million before taxes, with $208 million being in the fourth quarter. These
charges were equivalent to $0.86 per share for the year.


                                       10
<PAGE>   11


         Results for 1997 also included an accrual for profit sharing of $122
million, which was 7.82 percent of eligible payroll. There was no profit sharing
in 1996.

         Excluding these divested activities, TI orders were up 22 percent for
the year and revenues were up 19 percent, primarily due to growth in
semiconductor.

         Royalty revenues in 1997 were essentially steady with 1996.

         Interest income for 1997 was up $84 million from 1996, primarily as a
result of investment of net proceeds from the sale of the defense business to
Raytheon.

         The income tax rate for 1997 was 35 percent.

         TI's backlog of unfilled orders as of December 31, 1997, was $1623
million, unchanged from year-end 1996.

         R&D for 1997 was $1075 million, excluding the $461 million charge for
in-process R&D associated with the Amati acquisition, compared with $989 million
in 1996, excluding the $192 million charge for in-process R&D associated with
the SSi acquisition.

         Capital expenditures were $1238 million in 1997, compared with $2063
million in 1996. Depreciation for 1997 was $1109 million compared with $904
million in 1996.

         Excluding the effect of the special items for 1997, operating margin
was 12.4 percent, income was $809 million and earnings per share were $2.03. TI
believes that, for analytical purposes, the effect of these items should be
excluded from operating results because they are not necessarily indicative of
future operating results or of future financial condition. Additional
information relating to these items appears below under the heading "Special
Charges and Gains."

         SEMICONDUCTOR: Orders in semiconductor for 1997 were $6610 million, up
25 percent from $5267 million in 1996. The increase resulted from strong demand
for digital signal processing solutions (DSPS), as DSPS orders increased over 40
percent. Semiconductor revenues were $6514 million, up 21 percent from $5385
million in 1996. The increase in semiconductor resulted from an increase of more
than 35 percent in DSPS revenues due to increased shipments.

         For the fourth quarter, semiconductor revenues, which include royalties
from semiconductor patent licenses, represented about 71 percent of TI's
revenues. Digital signal processors plus mixed signal/analog represented about
54 percent of semiconductor. The remainder of semiconductor consists primarily
of a broad range of advanced products, including application-specific integrated
circuits, reduced instruction-set microprocessors, microcontrollers and standard
logic.

         Revenues reached record levels for digital signal processing for both
the year and the fourth quarter. Mixed-signal/analog also had a strong year,
with record revenues for the year and fourth quarter, growing more than twice as
fast as the market in 1997.


                                       11
<PAGE>   12
         TI's other semiconductor products, such as microcontrollers and
application-specific integrated circuits, made good progress in growth and
profitability in 1997.

         Semiconductor profit from operations increased from $1012 million in
1996 to $1546 million in 1997, and operating margin improved from 18.8 percent
to 23.7 percent. Results particularly benefited from higher DSPS shipments.

         MATERIALS & CONTROLS (M&C): Orders in M&C of $972 million were up from
$896 million in 1996, primarily due to TIRIS. Revenues of $954 million were up
$64 million from 1996 due primarily to the growing acceptance of TIRIS in
automotive applications. PFO increased from $90 million in 1996 to $123 million
in 1997, with operating margin improving from 10.1 percent to 12.9 percent. The
increase was due primarily to manufacturing cost reduction.

         EDUCATIONAL & PRODUCTIVITY SOLUTIONS (E&PS): Orders in E&PS were $448
million, up $22 million from 1996 as a result of continued growth in
instructional calculators. Revenues were $447 million, an increase of $24
million from 1996 also as a result of growth in instructional calculators. PFO
increased from $56 million in 1996 to $59 million in 1997, and operating margin
remained flat at 13.2 percent.

         DIGITAL IMAGING: TI's digital imaging business continued to make
progress throughout 1997, further focusing its strategy on key market
opportunities.

         DIVESTED ACTIVITIES: Revenues for memory decreased $400 million in
1997, compared to 1996, as DRAM prices continued to decline sharply.

SPECIAL CHARGES AND GAINS

         FOURTH QUARTER OF 1998: In the fourth quarter of 1998, the company took
further steps to enhance manufacturing efficiency, including the announced
closing of a semiconductor assembly operation and sale of a materials & controls
manufacturing operation, both in Europe. The sale was completed on December 31,
1998. The primary benefit from these actions was the consolidation of
manufacturing facilities, which increased efficiencies and reduced manufacturing
costs. Estimated savings from such actions were approximately $24 million
annually. The benefit was expected to begin in the first quarter of 1999. The
assembly operation closing, which is ongoing, affected 740 employees. As a
result of these actions, the company took a fourth-quarter 1998 pretax charge of
$72 million, of which $27 million was included in cost of revenues, $24 million
in other income (expense) net and $21 million in marketing, general and
administrative expense. Of this $72 million charge, $35 million was for
severance, $35 million for other cash-related costs and $2 million for asset
write-downs, primarily to adjust fixed assets in the European materials &
controls operation to actual sale value. Of the $35 million severance charge,
$19 million had been paid by year-end 1998 and $16 million will be paid in 1999.
Of the other $35 million charge, $20 million was a cash payment required as part
of an agreement with the third-party buyer of a materials & controls
manufacturing operation in Europe. The balance was for previously-received
government grants expected to be repaid as a result of the closing of the
European semiconductor assembly operation.

         THIRD QUARTER OF 1998: In the third quarter of 1998, the company
recorded a $14 million charge for accelerated depreciation on fixed assets
primarily located in a


                                       12
<PAGE>   13


semiconductor manufacturing facility in Singapore. This action was taken in
connection with the severance/manufacturing efficiency program announced during
the second quarter of 1998 (which program is more fully described below under
the heading Second Quarter of 1998). This asset write-down charge was included
in cost of revenues.

         SECOND QUARTER OF 1998: In the second quarter of 1998, the company
announced that, as a result of the various business divestitures over the past
several years, the pending sale of its memory business (subsequently completed
in September 1998), and weakness at that time in the semiconductor market
environment, it was implementing a severance/manufacturing efficiency program in
order to more closely match the size and cost of its support functions with the
company's overall size and to further combine manufacturing resources for more
efficient operations. The primary benefit from this severance/manufacturing
efficiency program was reduced people costs; total benefits were estimated to
reach $270 million annually. The benefit was expected to begin in the third
quarter of 1998.

         The program, which primarily affected the company's corporate
activities and semiconductor business, included the elimination of 3,441 jobs
around the world through voluntary programs, attrition, outsourcing and layoffs,
as well as the closing of several facilities. As a result, the company took a
pretax charge of $219 million in the second quarter of 1998, of which $126
million was included in marketing, general and administrative expense and $93
million in cost of revenues. Of the $219 million charge, $161 million was for
severance, $41 million for asset write-downs and $17 million for vendor
cancellation and lease charges.

         Of the $41 million for asset write-downs, $25 million was for U.S.
semiconductor inventories and $16 million was for fixed assets, primarily
accelerated depreciation on assets phased out during 1998 in connection with the
winding down of production at a semiconductor manufacturing facility located in
Singapore. The primary benefits from this consolidation action were increased
efficiencies and reduced manufacturing costs. Estimated savings from such
actions were approximately $9 million annually. The benefit was expected to
begin in the fourth quarter of 1998.

         Of the $17 million for vendor cancellation and lease charges, $15
million was for required vendor fees for cancellation of purchase contracts for
chemicals, supplies and equipment as a result of a U.S. facility shutdown.

         At year-end 1998, the program had essentially been completed, with most
severance costs paid except for $49 million, which will primarily be paid in
1999. Of the 3,441 jobs, 3,260 had been eliminated, and 181 will be eliminated
in 1999.

         In the second quarter of 1998, the company sold its shares in the
TI-Acer DRAM semiconductor manufacturing joint venture to Acer Corporation for
$120 million in cash. This sale resulted in a pretax gain of $83 million,
included in other income.

         FIRST QUARTER OF 1998: In the first quarter of 1998, TI's U.S. DRAM
semiconductor manufacturing joint venture with Hitachi, Ltd. was discontinued as
a result of a combination of severe price declines and overcapacity in the DRAM
market. As part of this first quarter discontinuance, TI purchased the assets of
the venture for approximately $98 million. Also as part of this first quarter
discontinuance, TI and Hitachi decided to assume and share equally in the
payment of the venture's obligations. TI's share of those payments was $219
million, which was paid and charged to cost of revenues in the first quarter.

                                       13
<PAGE>   14
         In connection with TI's acquisitions of GO DSP and Spectron, both of
which occurred in the first quarter of l998, TI recorded charges of $10 million
and $15 million for purchased in-process R&D (purchased R&D), based upon the
appraised value of the related developmental projects. The Income Approach,
which included an analysis of the markets, cash flows, and risks associated with
achieving such cash flows, was the primary technique utilized in valuing each
purchased R&D project.

         GO DSP's and Spectron's research and development related to DSP
software tools. These software tools, which include real-time operating systems,
allow DSP systems developers to improve productivity and reduce time-to-market.
TI's goal in these acquisitions was to extend its leadership in digital signal
processing solutions by offering a complete development environment, simplifying
DSP development, and making TI DSP solutions even more attractive for a broad
range of fast-growing markets.

         Significant assumptions used in determining the value of purchased R&D
for GO DSP and Spectron included projected operating cash flows and the discount
rate. Projected operating cash flows were expected to begin in late 1998. The
discount rate selected for GO DSP's and Spectron's in-process technologies was
30%.

         At the time of the acquisitions, GO DSP and Spectron management
estimated the remaining cost and time to complete the purchased R&D projects was
approximately $7 million and 540 engineer-months. The term "engineer-month"
refers to the average amount of research work expected to be performed by an
engineer in a month. All the in-process projects were essentially completed on
schedule. TI expects to essentially meet its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects acquired were the most significant and
uncertain assumptions utilized in the valuation analysis of the in-process
research and development. Uncertainties regarding projected operating cash flows
could give rise to unforeseen budget over-runs and/or revenue shortfalls in the
event that TI is unable to successfully commercialize the projects. TI
management is primarily responsible for estimating the value of the purchased
R&D in all acquisitions accounted for under the purchase method.

         FOURTH QUARTER OF 1997: In connection with TI's acquisition of Amati
Communications Corporations (Amati) in the fourth quarter of 1997, TI recorded a
charge of $461 million for the value of purchased in-process R&D (purchased R&D)
at the acquisition date, based upon the appraised value of the related
developmental projects. The Income Approach, which included an analysis of the
markets, cash flows, and risks associated with achieving such cash flows, was
the primary technique utilized in valuing each purchased R&D project.

         Amati's research and development related to Digital Subscriber Line
(DSL) system designs for the Internet and other uses. DSL technology targets the
local exchange carrier market since the technology permits the transmission of
data at high speeds over the existing copper lines of the local exchange
carriers. Currently, analog modems are noted as being slow in


                                       14
<PAGE>   15


their transmission speed, and ADSL digital processing technology is expected to
fill the need for additional bandwidth requirements. VDSL transmits high-speed
data over short reaches of twisted-pair copper telephone wire, with a range of
speeds that depends on actual line length.

         Significant assumptions used in determining the value of purchased R&D
for Amati included projected operating cash flows and the discount rate.
Projected operating cash flows were expected to begin in 1999. The discount rate
selected for Amati's in-process technologies was 30%.

         At the time of the acquisition, Amati management estimated the
remaining cost to complete the purchased R&D projects to be approximately $13
million with a remaining time requirement of approximately 1,300
engineer-months. The term "engineer-month" refers to the average amount of
research work to be performed by an engineer in a month. All the in-process
projects were essentially completed on schedule. Several products have been
released, and although the DSL market has developed more slowly than expected,
TI expects improvements in the near term in Internet-related demand. As this
occurs, TI will be one of a very few suppliers who have demonstrated
interoperability and standards compliance. Thus, TI expects to essentially meet
its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects acquired were the most significant and
uncertain assumptions utilized in the valuation analysis of the in-process
research and development. Uncertainties regarding projected operating cash flows
could give rise to unforeseen budget over-runs and/or revenue shortfalls in the
event that TI is unable to successfully commercialize the projects. TI
management is primarily responsible for estimating the value of the purchased
R&D in all acquisitions accounted for under the purchase method.

         In the fourth quarter of 1997, the company took a pretax charge of $42
million, of which $30 million was included in cost of revenues and $12 million
in marketing, general and administrative expense, primarily for severance costs
related to cost-reduction actions by the materials & controls business. These
actions, which are expected to be completed in first-quarter 1999, affected
approximately 260 employees. The terminated employees were in plants located in
Holland, Italy, Canada and Michigan. The primary benefit from this materials &
controls action was reduced people costs, which were estimated to reach $20
million annually. The benefit was expected to begin in the first quarter of
1998.

         SECOND QUARTER OF 1997: In the second quarter of 1997, TI sold several
activities, principally software, for a pre-tax gain of $66 million, after
transaction costs. These transaction costs totaled $54 million and included
severance of $17 million for 372 employees, who left TI within three months of
the related divestitures, $24 million for vendor and warranty obligations, $4
million for professional fees, and $9 million for various other costs. The
primary benefit from the related divestitures was the cessation of the software
business, which was operating at a loss of approximately $28 million in the
first half of 1997.

         FIRST QUARTER OF 1997: In the first quarter of 1997, the company sold
its mobile computing business and terminated its digital imaging printing
development program. The primary benefits from these actions were the
divestiture of a business operating at a loss and the termination of the
research and development program. The divested


                                       15
<PAGE>   16


business had a $180 million loss in 1996. The cost of the research and
development program in 1996 was $32 million. As a result of these actions, the
company took a first-quarter pretax charge of $56 million, of which $28 million
was included in cost of revenues and $28 million in marketing, general and
administrative expense. Of this $56 million charge, $27 million was for
severance for involuntary reductions worldwide. These severance actions were
essentially completed by the end of the quarter and affected approximately 1,045
employees. The balance of $29 million was for other costs associated with the
business sale and program termination, including vendor cancellation and lease
charges. Essentially all costs were paid in 1998.

         FOURTH QUARTER OF 1996: In the fourth quarter of 1996, the company took
a pretax charge of $208 million, of which $169 million was included in cost of
revenues and $39 million was included in marketing, general and administrative
expense. Of the $208 million, $91 million was for severance for employment
reduction actions in the United States and selected reductions worldwide. The
primary benefit from these actions was reduced people costs, which were
estimated to reach $195 million annually. The benefit was expected to begin in
the first quarter of 1997. These actions, which primarily involved the
semiconductor business as well as divested activities, were essentially
completed by year-end 1996 and affected approximately 2,600 employees. Of the
severance cost of $91 million, $34 million was paid in 1996 and $57 million was
paid in 1997.

         The balance of this charge, $117 million, was for vendor cancellation
and other cash-related costs of $47 million and asset write-downs of $70 million
on several product lines, primarily mobile computing, an operation divested in
first-quarter 1997. The asset write-downs were to adjust inventory and fixed
assets to actual sale value. Of the $70 million asset write-downs charges, $54
million was for mobile computing.

         With respect to this $54 million charge, $47 million was for inventory
and $7 million was for fixed assets. The balance of $16 million included a $6
million charge against operating assets for the impact of the expected first
quarter 1997 termination of TI's digital imaging printing development program.
The benefit of this action is described above under the heading First Quarter of
1997. The remainder, $10 million, was to write down the operating assets of TI's
Telecom business, which was held for sale, and sold in the second quarter of
1997 for a nominal gain. The primary benefit from this action was the
divestiture of a business operating at a loss ($14 million in 1996).

         THIRD QUARTER OF 1996: In connection with TI's acquisitions of Silicon
Systems, Inc. (SSi) in the third quarter of 1996, TI recorded a charge of $192
million for the value of purchased in-process R&D (purchased R&D) at the
acquisition date, based upon the appraised value of the related developmental
projects. The Income Approach, which included an analysis of the markets, cash
flows, and risks associated with achieving such cash flows, was the primary
technique utilized in valuing each purchased R&D project.

         SSi's research and development related to analog technology for hard
disk drives and removable storage devices. Historically, SSi had primarily
emphasized producing integrated circuits for the hard disk drive market. As of
the acquisition date, SSi's product development activities for this market had
been expanded to include other magnetic optical storage devices that require
advanced technology and performance.

         Significant assumptions used in determining the value of purchased R&D
for SSi included projected operating cash flows and the discount rate. Projected
operating cash flows were expected to commence in late 1996. The discount rate
selected for SSi's in-process technologies was 22%.

         At the time of the acquisition SSi management estimated the remaining
cost to complete the purchased R&D projects to be approximately $16 million,
over a 9-month period. All the in-process projects were essentially completed on
schedule. TI expects to essentially meet its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects were the most significant and uncertain
assumptions utilized in the valuation analysis of the in-process research and
development. Uncertainties regarding projected operating cash flows could give
rise to unforeseen budget over-runs and/or revenue shortfalls in the event that
TI is unable to successfully commercialize the projects. TI management is
primarily responsible for estimating the value of the purchased R&D in all
acquisitions accounted for under the purchase method.

Notes to Financial Statements


ACCOUNTING POLICIES AND PRACTICES

         The company adopted SFAS No. 130 in the first quarter of 1998. It
required disclosure of comprehensive income, i.e., net income plus direct
adjustments to stockholders' equity such as equity, debt and cash investment
adjustments and pension liability adjustments. Also in 1998, the company adopted
SFAS No. 132, which mandated changes in disclosures for pension and retiree
health care plans. In 1997, the company adopted SFAS No. 128, which required
disclosure of two new earnings per share amounts (diluted and basic) and
elimination of prior earnings per share amounts. Also in 1997, the company
adopted SFAS No. 131, which required a new basis of determining reportable
business segments, i.e., the management approach. Disclosures under these 1997
and 1998 standards were provided on a retroactive basis. None affected reported
net income.

         Accounting standard SFAS No. 133 was issued in 1998 and is effective in
2000. It requires that all derivatives be marked-to-market on an ongoing basis.
This applies whether the derivatives are stand-alone instruments, such as
forward currency exchange contracts and interest rate swaps, or embedded
derivatives, such as call options contained in convertible debt investments.
Along with the derivatives, the underlying hedged items are also to be
marked-to-market on an ongoing basis. These market value adjustments are to be
included either in the income statement or stockholders' equity, depending on
the nature of the transaction. The company expects to adopt the standard in the
first quarter of 2000 on a cumulative basis. Based on analysis to date, the
company expects the most significant impact of this standard will be the
cumulative, as well as ongoing mark-to-market, adjustment through the income
statement of the embedded call option on Micron Technology, Inc. (Micron) common
shares contained in the convertible note received from Micron in connection with
TI's 1998 sale of its memory business. The value of this option can be volatile
given its sensitivity to changes in the value of Micron common shares. For
example, at September 30, 1998, the estimated value of the option was $82
million; at December 31, 1998, it was $192 million. Under SFAS No. 133, this
change in value of $110 million would be included in the income statement. Under
current accounting principles, the change in value of the Micron convertible
note, including the embedded call, is an adjustment to stockholders' equity.

         Accounting standard SOP 98-1 was issued in 1998 and is effective in
1999. It requires capitalization of the development costs of software to be used
internally, e.g., for manufacturing or administrative processes. The company,
which currently capitalizes significant development costs for internal-use
software, expects to adopt the standard in the first quarter of 1999 for
developmental costs incurred in that quarter and thereafter. The effect is not
expected to be material. Accounting standard SOP 98-5 was issued in 1998 and is
effective in 1999. It requires expensing, rather than capitalizing, the cost of
start-up activities. The company currently expenses such amounts as incurred and
therefore expects no material effect from adoption of this standard.

         The consolidated financial statements include the accounts of all
subsidiaries. The preparation of financial statements requires the use of
estimates from which final results may vary. Intercompany balances and
transactions have been eliminated. Certain amounts in prior


                                       23
<PAGE>   24


years' financial statements and related notes have been reclassified to conform
to the 1998 presentation. 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), deferred income taxes, 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. Net currency exchange gains and losses
from remeasurement and forward currency exchange contracts to hedge net balance
sheet exposures are charged or credited on a current basis to other income
(expense) net. Gains and losses from forward currency exchange contracts to
hedge specific transactions are deferred and included in the measurement of the
related transactions. Gains and losses from interest rate swaps are included on
the accrual basis in interest expense. Gains and losses from terminated forward
currency exchange contracts and interest rate swaps are deferred and recognized
consistent with the terms of the underlying transaction.

         As discussed in the Divestitures note, the consolidated financial
statements include the effect of two significant divestitures: the sale of the
company's memory business and related joint venture interests to Micron in
September 1998, which was accounted for as a sale of a business, and the sale of
the defense business to Raytheon Company in July 1997, which was accounted for
as a discontinued operation.

         The description "accounted for as a sale of a business" means the sale
of TI's memory business, which was a portion of the company's Semiconductor
segment, was not accounted for as a discontinued operation under APB No. 30, but
as a part of continuing operations, as discussed in paragraph 13 of that
opinion.

         The description "accounted for as a discontinued operation" means the
sale of TI's Defense Systems and Electronics segment was accounted for under APB
No. 30, paragraph 8, as the disposal of a segment of a business. Accordingly,
the operating results and gain on the sale of this business were presented in
TI's financial statements as discontinued operations, separate from TI's
continuing operations.

         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) or average basis.

         Revenues are generally recognized as products are shipped. Royalty
revenue is recognized by the company upon fulfillment of its contractual
obligations and determination of a fixed royalty amount or, in the case of
ongoing royalties, upon sale by the licensee of royalty-bearing products, as
estimated by the company.

         Depreciation is computed by either the declining-balance method
(primarily 150 percent declining method) or the sum-of-the-years-digits method.
Fully depreciated assets are written off against accumulated depreciation.
Advertising costs are expensed as incurred. Advertising expense was $100 million
in 1998, $128 million in 1997 and $124 million in 1996.

</TABLE>

         The EPS computation for 1996 excludes 4.8 million shares for stock
options/compensation plans and 5.0 million shares for convertible debentures
because their effect would have been antidilutive.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

         Debt securities with original maturities within three months are
considered cash equivalents. Debt securities with original maturities beyond
three months have remaining maturities within 13 months and are considered
short-term investments. These cash equivalent and short-term investment debt
securities are available for sale and stated at fair value, which approximates
their specific amortized cost. As of December 31, 1998, these debt securities
consisted primarily of the following types: corporate ($1092 million) and
asset-backed commercial paper ($679 million). At December 31, 1997, these debt
securities consisted primarily of the following types: corporate ($1943 million)
and asset-backed commercial paper ($623 million). Gross realized and unrealized
gains and losses for each of these security types were immaterial in 1998, 1997
and 1996. Proceeds from sales of these cash equivalent and short-term investment
debt securities in 1998, 1997 and 1996 were $647 million, $859 million and $10
million.

         Prior to the sale of its memory business to Micron in 1998, TI
participated in DRAM manufacturing joint ventures. TI held minority interests
in, and had long-term inventory purchase commitments with, each joint venture.
Under the agreements, TI purchased the output of the ventures at prices based
upon percentage discounts from TI's average selling prices.


                                       25

Inventory purchases from the ventures aggregated $416 million in 1998, $977
million in 1997 and $1176 million in 1996. Receivables from and payables to the
ventures were $135 million and $69 million at December 31, 1997. TI amortized
its cost of the ventures over the expected initial output period of three to
five years, and recognized its share of any cumulative venture net losses in
excess of amortization. The related expense charged to operations was $40
million in 1998, $88 million in 1997 and $33 million in 1996.

INVESTMENTS

         At year-end 1998, equity investments primarily consisted of 28,933,092
Micron common shares, along with several other publicly traded investments. Debt
investments consisted of 6.5% Micron convertible and subordinated notes. The
convertible note (convertible into 12,333,358 Micron common shares at $60 per
share) and the subordinated note have face amounts of $740 million and $210
million. The notes, which mature in 2005, have a weighted-average imputed
interest rate of 8.7%. The Micron securities were received in 1998 in connection
with TI's sale of its memory business.

         TI Ventures is an externally managed venture fund which invests in the
development of new markets. As of year-end 1998, it had invested in 14 companies
focused on next-generation applications of digital signal processors.

         Other investments consist of mutual funds that are acquired to generate
returns that offset changes in certain liabilities related to deferred
compensation arrangements. The mutual funds hold a variety of debt and equity
investments.

         Investments are stated at fair value, which is based on market quotes,
current interest rates or management estimates, as appropriate. Adjustments to
fair value of the equity and debt investments, which are classified as
available-for-sale, are recorded as an increase or decrease in stockholders'
equity. Adjustments to fair value of the venture fund are recorded in other
income (expense) net. Adjustments to fair value of the other investments, which
are classified as trading, are recorded in operating expense. Cost or amortized
cost, as appropriate, was determined on a specific identification basis.
Proceeds from sales of equity and debt investments were zero in 1998, $26
million in 1997 and zero in 1996. There were no gross realized gains or losses
from sales of equity and debt investments in 1998 and 1996, and there was a $16
million gain in 1997.

NON-CASH INVESTING ACTIVITIES

         Following are descriptions of those divestitures and acquisitions by TI
which involved significant non-cash amounts. In September, 1998, TI sold its
memory business to Micron Technology, Inc. (Micron). As a result, TI received
Micron common shares and notes with values of $881 million and $836 million,
respectively. In addition to TI's memory assets, Micron received $550 million in
cash from TI to facilitate the deployment of Micron's technology throughout the
acquired business. In the fourth quarter of 1998, TI made an additional $130
million payment to Micron as part of the contractually required working capital.
TI deferred the estimated pretax gain of $127 million on the sale of the memory
business until the recovery of the TI-provided financing.

         In July 1996, TI acquired Silicon Systems, Inc. by means of a stock
purchase agreement for $340 million in cash plus the assumption of $217 million
of 5-year installment notes and $61 million of current liabilities. Of the
aggregate purchase price of $618 million, TI recorded $426 million for the value
of assets acquired, $192 million for the value of acquired in-process research
and development, and $278 million for the value of liabilities assumed.

         The coupon rates for the notes due 2006 have been swapped for
LIBOR-based variable rates through 2006, for an effective interest rate of
approximately 4.6% and 5.1% as of December 31, 1998 and 1997. The lira notes,
and related swaps, are due in installments through 2005.

         As a result of a 1997 tender offer for any or all of the company's
9.0%, 9.25% and 8.75% notes, an aggregate of $248 million of debt principal was
tendered at a cash price of $280 million. This resulted in an extraordinary
charge of $22 million in the fourth quarter of 1997, after elimination of
deferred issuance costs and recognition of an income tax effect of $12 million.

         Interest incurred on loans in 1998, 1997 and 1996 was $85 million, $114
million and $108 million. Of these amounts, $10 million in 1998, $20 million in
1997 and $35 million in 1996 were capitalized as a component of capital asset
construction costs. Interest paid on loans (net of amounts capitalized) was $75
million in 1998, $94 million in 1997 and $54 million in 1996.

         Aggregate maturities of long-term debt due during the four years
subsequent to December 31, 1999, are as follows:

         The company maintains lines of credit to support commercial paper
borrowings and to provide additional liquidity. These lines of credit totaled
$669 million at December 31, 1998, and $651 million at December 31, 1997. Of
these amounts, at December 31, 1998 and 1997, $600 million existed to support
outstanding commercial paper borrowings or short-term bank loans.


FINANCIAL INSTRUMENTS AND RISK CONCENTRATION

         FINANCIAL INSTRUMENTS: In addition to the swaps discussed in the
preceding note, as of December 31, 1998, the company had forward currency
exchange contracts outstanding of $756 million to hedge net balance sheet
exposures (including $161 million to sell yen, $132 million to buy lira and $105
million to buy deutsche marks). At December 31, 1997, the company had forward
currency exchange contracts outstanding of $275 million to hedge net balance
sheet exposures (including $101 million to buy lira, $73 million to buy deutsche
marks and $24 million to buy Singapore dollars). As of December 31, 1998 and
1997, the carrying amounts and current market settlement values of these swaps
and forward contracts were not significant. The company uses forward currency
exchange contracts, including the lira note currency swaps, to minimize the
adverse earnings impact from the effect of exchange rate fluctuations on the
company's non-U.S. dollar net balance sheet exposures. The interest rate swaps
for the company's notes due 2006 are used to change the characteristics of the
interest rate stream on the debt from fixed rates to short-term variable rates
in order to achieve a mix of interest rates that, over time, is expected to
moderate financing costs. The effect of these interest rate swaps was to reduce
interest expense by $3 million and $2 million in 1998 and 1997, and increase
interest expense by $2 million in 1996.

         In order to minimize its exposure to credit risk, the company limits
its counterparties on the forward currency exchange contracts and interest rate
swaps to investment-grade rated financial institutions.

         As of December 31, 1998 and 1997, the fair value of long-term debt,
based on current interest rates, was approximately $1346 million and $1390
million, compared with the historical cost amount of $1294 million and $1353
million.

         RISK CONCENTRATION: Financial instruments that potentially subject the
company to concentrations of credit risk are primarily cash investments,
accounts receivable and noncurrent investments. The company places its cash
investments in investment-grade, short-term debt securities and limits the
amount of credit exposure to any one commercial issuer. Concentrations


                                       29
<PAGE>   30


of credit risk with respect to the receivables are limited due to the large
number of customers in the company's customer base and their dispersion across
different industries and geographic areas. The company maintains an allowance
for losses based upon the expected collectibility of accounts receivable. The
company's noncurrent investments at year-end 1998 have an aggregate fair value
of $2564 million. The investments are in high-technology companies and are
subject to price volatility and other uncertainties. They include a significant
concentration of Micron debt (fair value of $978 million) and equity instruments
(fair value of $1463 million). The company adjusts the carrying amounts of the
investments to fair value each quarter.


STOCKHOLDERS' EQUITY

         The company is authorized to issue 10,000,000 shares of preferred
stock. None is currently outstanding.

         Each outstanding share of the company's common stock carries a stock
purchase right. Under certain circumstances, each right may be exercised to
purchase one one-thousandth of a share of the company's participating cumulative
preferred stock for $200. Under certain circumstances following the acquisition
of 20% or more of the company's outstanding common stock by an acquiring person
(as defined in the rights agreement), each right (other than rights held by an
acquiring person) may be exercised to purchase common stock of the company or a
successor company with a market value of twice the $200 exercise price. The
rights, which are redeemable by the company at 1 cent per right, expire in June
2008.

         Changes in other comprehensive income are as follows:

RESEARCH AND DEVELOPMENT EXPENSE

         Research and development expense, which totaled $1206 million in 1998,
$1536 million in 1997 and $1181 million in 1996, included a charge in 1998 of
$25 million for the value of acquired in-process research and development from
two business acquisitions, GO DSP and Spectron. Research and development expense
for 1997 included a charge of $461 million for the


                                       30
<PAGE>   31


value of acquired in-process research and development as a result of the
acquisition of Amati Communications Corporation (Amati). The company acquired
Amati as a result of an all-cash tender offer in fourth quarter 1997 through
which approximately 78% of Amati's outstanding common shares were acquired for
an aggregate of $306 million. As contractually required, the company then
acquired the balance of the Amati shares through a second-step merger
transaction for an aggregate of $91 million. In addition to these stock purchase
costs, the company incurred approximately $117 million of additional acquisition
costs, which included $50 million for the value of TI common stock options
contractually required to be issued to replace outstanding Amati employee stock
options. Research and development expense for 1996 included a charge of $192
million for the value of acquired in-process research and development in
connection with the 1996 acquisition of Silicon Systems, Inc. (SSi) for $618
million. There was essentially no tax offset associated with these acquired
in-process research and development charges.

         In connection with TI's acquisitions of GO DSP and Spectron, both of
which occurred in the first quarter of l998, TI recorded charges of $10 million
and $15 million for purchased in-process R&D (purchased R&D), based upon the
appraised value of the related developmental projects. The Income Approach,
which included an analysis of the markets, cash flows, and risks associated with
achieving such cash flows, was the primary technique utilized in valuing each
purchased R&D project.

         GO DSP's and Spectron's research and development related to DSP
software tools. These software tools, which include real-time operating systems,
allow DSP systems developers to improve productivity and reduce time-to-market.
TI's goal in these acquisitions was to extend its leadership in digital signal
processing solutions by offering a complete development environment, simplifying
DSP development, and making TI DSP solutions even more attractive for a broad
range of fast-growing markets.

         Significant assumptions used in determining the value of purchased R&D
for GO DSP and Spectron included projected operating cash flows and the discount
rate. Projected operating cash flows were expected to begin in late 1998. The
discount rate selected for GO DSP's and Spectron's in-process technologies was
30%.

         At the time of the acquisitions, GO DSP and Spectron management
estimated the remaining cost and time to complete the purchased R&D projects was
approximately $7 million and 540 engineer-months. The term "engineer-month"
refers to the average amount of research work expected to be performed by an
engineer in a month. All the in-process projects were essentially completed on
schedule. TI expects to essentially meet its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects acquired were the most significant and
uncertain assumptions utilized in the valuation analysis of the in-process
research and development. Uncertainties regarding projected operating cash flows
could give rise to unforeseen budget over-runs and/or revenue shortfalls in the
event that TI is unable to successfully commercialize the projects. TI
management is primarily responsible for estimating the value of the purchased
R&D in all acquisitions accounted for under the purchase method.

         In connection with TI's acquisition of Amati Communications
Corporations (Amati) in the fourth quarter of 1997, TI recorded a charge of $461
million for the value of purchased in-process R&D (purchased R&D) at the
acquisition date, based upon the appraised value of the related developmental
projects. The Income Approach, which included an analysis of the markets, cash
flows, and risks associated with achieving such cash flows, was the primary
technique utilized in valuing each purchased R&D project.

         Amati's research and development related to Digital Subscriber Line
(DSL) system designs for the Internet and other uses. DSL technology targets the
local exchange carrier market since the technology permits the transmission of
data at high speeds over the existing copper lines of the local exchange
carriers. Currently, analog modems are noted as being slow in their transmission
speed, and ADSL digital processing technology is expected to fill the need for
additional bandwidth requirements. VDSL transmits high-speed data over short
reaches of twisted-pair copper telephone wire, with a range of speeds that
depends on actual line length.

         Significant assumptions used in determining the value of purchased R&D
for Amati included projected operating cash flows and the discount rate.
Projected operating cash flows were expected to begin in 1999. The discount rate
selected for Amati's in-process technologies was 30%.

         At the time of the acquisition, Amati management estimated the
remaining cost to complete the purchased R&D projects to be approximately $13
million with a remaining time requirement of approximately 1,300
engineer-months. The term "engineer-month" refers to the average amount of
research work to be performed by an engineer in a month. All the in-process
projects were essentially completed on schedule. Several products have been
released, and although the DSL market has developed more slowly than expected,
TI expects improvements in the near term in Internet-related demand. As this
occurs, TI will be one of a very few suppliers who have demonstrated
interoperability and standards compliance. Thus, TI expects to essentially meet
its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects acquired were the most significant and
uncertain assumptions utilized in the valuation analysis of the in-process
research and development. Uncertainties regarding projected operating cash flows
could give rise to unforeseen budget over-runs and/or revenue shortfalls in the
event that TI is unable to successfully commercialize the projects. TI
management is primarily responsible for estimating the value of the purchased
R&D in all acquisitions accounted for under the purchase method.

         In connection with TI's acquisitions of Silicon Systems, Inc. (SSi) in
the third quarter of 1996, TI recorded a charge of $192 million for the value of
purchased in-process R&D (purchased R&D) at the acquisition date, based upon the
appraised value of the related developmental projects. The Income Approach,
which included an analysis of the markets, cash flows, and risks associated with
achieving such cash flows, was the primary technique utilized in valuing each
purchased R&D project.

         SSi's research and development related to analog technology for hard
disk drives and removable storage devices. Historically, SSi had primarily
emphasized producing integrated circuits for the hard disk drive market. As of
the acquisition date, SSi's product development


                                       32
<PAGE>   33


activities for this market had been expanded to include other magnetic optical
storage devices that require advanced technology and performance.

         Significant assumptions used in determining the value of purchased R&D
for SSi included projected operating cash flows and the discount rate. Projected
operating cash flows were expected to commence in late 1996. The discount rate
selected for SSi's in-process technologies was 22%.

         At the time of the acquisition SSi management estimated the remaining
cost to complete the purchased R&D projects to be approximately $16 million,
over a 9-month period. All the in-process projects were essentially completed on
schedule. TI expects to essentially meet its original return expectations.

         The relative stage of completion and projected operating cash flows of
the underlying in-process projects were the most significant and uncertain
assumptions utilized in the valuation analysis of the in-process research and
development. Uncertainties regarding projected operating cash flows could give
rise to unforeseen budget over-runs and/or revenue shortfalls in the event that
TI is unable to successfully commercialize the projects. TI management is
primarily responsible for estimating the value of the purchased R&D in all
acquisitions accounted for under the purchase method.

STOCK OPTIONS

         The company has stock options outstanding to participants under the
Texas Instruments 1996 Long-Term Incentive Plan, approved by stockholders on
April 18, 1996. Options are also outstanding under the 1988 Stock Option Plan
and the Texas Instruments Long-Term Incentive Plan; however, no further options
may be granted under these plans. Under all these stockholder-approved plans,
unless the options are acquisition-related replacement options, 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 the options have a 10-year term. Options granted
subsequent to 1996 generally vest ratably over four years. Options granted prior
to that are fully vested.

         Under the 1996 Long-Term Incentive Plan, the company may grant stock
options, including incentive stock options; restricted stock and restricted
stock units; performance units;


                                       33
<PAGE>   34


and other stock-based awards. The plan provides for the issuance of 37,000,000
shares of the company's common stock (plus shares subject to acquisition-related
replacement options); in addition, if any award under the 1988 Stock Option Plan
or the Long-Term Incentive Plan terminates, then any unissued shares subject to
the terminated award become available for granting awards under the 1996
Long-Term Incentive Plan. No more than 4,000,000 shares of common stock may be
awarded as restricted stock, restricted stock units or other stock-based awards
under the plan. In 1998, 1997 and 1996, 117,000, 201,500 and 110,028 shares of
restricted stock units, which vest over one to five years, were granted
(weighted-average award-date value of $51.80, $37.78 and $22.65 per share). In
addition, in 1998, 1997 and 1996, zero, 5,700 and 69,812 previously unissued
shares were issued as Annual Incentive Plan stock awards (weighted-average
award-date value of zero, $22.94 and $23.28 per share). Compensation expense for
restricted stock units and annual stock awards totaled $3.9 million, $3.5
million and $1.6 million in 1998, 1997 and 1996.

         The company also has stock options outstanding under the Employee Stock
Purchase Plan approved by 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 that will be equal to
or greater than the purchase price, options granted become exercisable seven
months, and expire not more than 13 months, from date of grant. There are no
options outstanding under the 1988 Employee Stock Option Purchase Plan, the
predecessor to the Employee Stock Purchase Plan.

         Under the Stock Option Plan for Non-Employee Directors adopted in April
1998, the company will grant stock options to each non-employee director, once a
year, in the period beginning January 1999 and extending through 2003. Each
grant will be an option to purchase 5,000 shares with an option price equal to
fair market value on the date of grant. The option will vest ratably over four
years. Stock option transactions during 1998, 1997 and 1996 were as follows:

***  Aggregate value of $52 million for two acquisitions.

         In accordance with the terms of APB No. 25, the company records no
compensation expense for its stock option awards. As required by SFAS No. 123,
the company provides the following disclosure of hypothetical values for these
non-acquisition-related awards. The weighted-average grant-date value of options
granted during 1998, 1997 and 1996 was estimated to be $22.15, $15.72 and $9.24
under the Long-Term Incentive Plans and the 1988 Stock Option Plan (Long-Term
Plans) and $13.34, $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 1998, 1997 and 1996: expected dividend yields of .71%, .93% and
1.48% (Long-Term Plans) and .74%, .70% and 1.21% (Employee Plans); expected
volatility of 43%, 39% and 39%; risk-free interest rates of 5.47%, 5.76% and
5.42% (Long-Term Plans) and 5.32%, 5.69% and 6.15% (Employee Plans); and
expected lives of 6 years (Long-Term Plans) and .8 years, .8 years and 1.5 years
(Employee Plans). Had compensation expense been recorded based on these
hypothetical values, the company's 1998 net income would have been $328 million,
or diluted earnings per share of $0.81. A similar computation for 1997 and 1996
would have resulted in net income of $1764 million and $40 million, or diluted
earnings per share of $4.43 and $0.11. Because options vest over several years
and additional option grants are expected, the effects of these hypothetical
calculations are not likely to be representative of similar future calculations.

outstanding options, 280,229 are exercisable at year-end 1998.

         At year-end 1998, 21,861,771 shares were available for future grants
under the 1996 Long-Term Incentive Plan and 7,518,268 shares under the Employees

option and incentive plans and 8,667,092 shares were reserved for issuance under
the Employee Stock Purchase Plan.

         In 1997, the company began a stock repurchase program with the goal of
neutralizing the dilutive effect of shares to be issued upon the exercise of
stock options under the Employee Stock Purchase Plan and Long-Term Plans.
Treasury shares acquired in connection with this repurchase program and other
stock transactions in 1998, 1997 and 1996 were 4,463,283 shares, 754,511 shares
and 7,730 shares. Previously unissued common shares issued under the Long-Term
Plans and the Annual Incentive Plan in 1998, 1997 and 1996 were 33,848 shares,
30,174 shares and 98,072 shares. Treasury shares issued under the Texas
Instruments Restricted Stock Unit Plan for Directors in 1998, 1997 and 1996 were
zero shares, zero shares and 2,334 shares.


RETIREMENT AND INCENTIVE PLANS

         The company provides various retirement plans for employees including
pension, savings and deferred profit sharing plans. Incentive plans include
profit sharing payments and annual performance awards.

         U.S. RETIREMENT PLANS: Effective January 1, 1998, for U.S. employees
hired on or after December 1, 1997, the company provides a defined contribution
plan whereby the company contributes 2% of an employee's earnings, and a matched
savings program whereby an employee's contribution, up to 4% of the employee's
earnings, is matched by the company at a dollar-per-dollar rate. The
contributions may be invested in several investment funds including TI common
stock. During a selection period in 1997, employees employed prior to December
1, 1997, irrevocably elected whether to choose this plan or remain in the
savings and defined benefit programs described below. Approximately 36% chose
this plan.

         For U.S. employees hired prior to December 1, 1997, the company
provides a matched savings program whereby an employee's contribution, up to 4%
of the employee's earnings (subject to statutory limitations), is matched by the
company at the rate of 50 cents per dollar. Available investments are the same
as above. Also provided is a defined benefit plan with 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. The board of directors of the company has
expressed an intent to make such amendments in the future, circumstances
permitting, and the expected effects of such amendments have been considered in
calculating U.S. pension expense.

         Certain of the profit sharing plans worldwide provide that, depending
on the individual plan, a portion of the profit sharing earned by employees is
contributed to a deferred plan. For U.S. employees, 50% of profit sharing
amounts are deferred. Several investment options are available, including TI
common stock. While the board of directors of the company has authorized the
issuance of 9,233,836 shares of previously unissued TI common shares for
deferred profit sharing and savings plans worldwide, none have been issued in
the three years ended December 31, 1998. Instead, the trustees of these plans
worldwide have purchased outstanding TI common shares: 3,753,084 shares in 1998,
3,535,471 shares in 1997 and 3,123,905 shares in 1996.


                                       36
<PAGE>   37

         The company's aggregate expense for U.S. employees under the defined
contribution, deferred profit sharing and matched savings plans was $56 million
in 1998, $55 million in 1997 and $17 million in 1996.

         The company's U.S. employees are currently eligible to receive, during
retirement, specified company-paid medical benefits. The plan is contributory
and premiums are adjusted annually. For employees retiring on or after January
5, 1993, the company has specified a maximum annual amount per retiree, based on
years of service, that it will pay toward retiree medical premiums. For
employees who retired prior to that date, the company maintains a consistent
level of cost sharing between the company and the retiree. Effective January 1,
1998, new employees are eligible for this benefit when they reach 20 years of
service, regardless of age. For a 15-year transition period, current employees
qualify for eligibility under either the 20-year rule or the previous
requirement, which was based upon retirement eligibility under the defined
benefit pension plan. Coverage eligibility under the 20-year rule is only
available at termination, i.e., no subsequent election to participate is
allowable.

         Expense of the U.S. defined benefit and retiree health care benefit
plans was as follows:

         The U.S. defined benefit and retiree health care obligations for 1998
and 1997 were determined using assumed discount rates of 6.75% and 7.0%. The
assumed average long-term pay progression rate was 4.25%. The assumed long-term
rate of return on plan assets was 9.0%. The retiree health care benefit
obligation was determined using health care cost trend rates of 6.0% for 1999
decreasing to 5.0% by 2000. Increasing (decreasing) the health care cost trend
rates by 1% would have increased (decreased) the retiree health care benefit
obligation at December 31, 1998, by $15 million/$(15) million and 1998 plan
expense by $1 million/ $(1) million.

         NON-U.S. RETIREMENT PLANS: Retirement coverage for non-U.S. employees
of the company is provided, to the extent deemed appropriate, through separate
plans. Defined retirement benefits are based on years of service and employee's
compensation, generally during a fixed number of years immediately prior to
retirement.

         Certain non-U.S. locations provide for deferral of profit sharing
amounts with contributions generally invested in TI common stock. The related
expense for these contributions was $3 million in 1998, $6 million in 1997 and
zero in 1996.

         Expense of the non-U.S. defined benefit plans was as follows:

         The range of assumptions used for the non-U.S. defined benefit plans
reflects the different economic environments within the various countries.

         The defined benefit obligations were determined as of September 30
using a range of assumed discount rates of 2.5% to 7.0% and a range of assumed
average long-term pay progression rates of 3.0% to 6.0%. The range of assumed
long-term rates of return on plan assets was 7.0% to 8.0%. Accrued retirement at
September 30, 1998 and 1997 includes projected benefit obligations of $841
million and $883 million and accumulated benefit obligations of


                                       39

$630 million and $636 million, versus plan assets of $395 million and $408
million, for three plans whose obligations exceed their assets.

RESTRUCTURING ACTIONS

         In the second quarter of 1998, the company announced that, as a result
of the various business divestitures over the past several years, the pending
sale of its memory business and weakness in the current semiconductor market
environment, it was implementing a severance/manufacturing efficiency program in
order to more closely match the size and cost of its support functions with the
company's overall size and to further combine manufacturing resources for more
efficient operations. The program, which primarily affected the company's
corporate activities and semiconductor business, included the elimination of
3,441 jobs around the world through voluntary programs, attrition, outsourcing
and layoffs, as well as the closing of several facilities. As a result, the
company took a pretax charge of $219 million in the second quarter, of which
$126 million was included in marketing, general and administrative expense and
$93 million in cost of revenues. Of the $219 million charge, $161 million was
for severance, $41 million for asset write-downs and $17 million for vendor
cancellation and lease charges. Of the $41 million for asset write-downs, $25
million was for U.S. semiconductor inventories and $16 million was for fixed
assets, primarily accelerated depreciation on assets phased out during 1998 in
connection with the winding down of production at a semiconductor manufacturing
facility in Singapore. The fixed assets were subsequently sold for scrap at a
nominal value. Of the $17 million for vendor cancellation and lease charges, $15
million was for required vendor fees for cancellation of purchase contracts for
chemicals, supplies and equipment as a result of a U.S. facility shutdown. At
year-end 1998, the program had essentially been completed, with most severance
costs paid except for $49 million, which will primarily be paid in 1999. Of the
3,441 jobs, 3,260 had been eliminated, and 181 will be eliminated in 1999.

         In the third quarter of 1998, the company recorded a $14 million charge
for additional depreciation on fixed assets primarily located in the
semiconductor manufacturing facility in Singapore. This action was taken in
connection with the severance/manufacturing efficiency program announced during
the second quarter of 1998. This asset write down charge was included in cost of
revenues.

         In the fourth quarter of 1998, the company took further steps to
enhance manufacturing efficiency, including the announced closing of a
semiconductor assembly operation and sale of a materials & controls
manufacturing operation, both in Europe. The sale was completed on December 31,
1998. The assembly operation closing, which is ongoing, affected 740 employees.
As a result of these actions, the company took a fourth-quarter 1998 pretax
charge of $72 million, of which $27 million was included in cost of revenues,
$24 million in other income (expense) net and $21 million in marketing, general
and administrative expense. Of this $72 million charge, $35 million was for
severance, $35 million for other cash-related costs and $2 million for asset
write-downs, primarily to adjust fixed assets in the European materials &
controls operation to actual sale value. Of the $35 million severance charge,
$19 million had been paid by year-end 1998 and $16 million will be paid in 1999.
Of the other $35 million charge, $20 million was a cash payment required as part
of an agreement with the third-party buyer of a materials & controls
manufacturing operation in Europe. The balance was for


                                       40
<PAGE>   41


previously-received government grants expected to be repaid as a result of the
closing of the European semiconductor assembly operation.

         In the first quarter of 1997, the company sold its mobile computing
business and terminated its digital imaging printing development program. As a
result of these divestitures, the company took a first-quarter pretax charge of
$56 million, of which $28 million was included in cost of revenues and $28
million in marketing, general and administrative expense. Of this $56 million
charge, $27 million was for severance for involuntary reductions worldwide.
These severance actions were essentially completed by the end of the quarter and
affected approximately 1,045 employees. The balance of $29 million was for other
costs associated with the business sale and program termination, including
vendor cancellation and lease charges. Essentially all costs were paid in 1998.
In the second quarter of 1997, TI sold several activities, principally software,
for a pre-tax gain of $66 million, after transaction costs. These transaction
costs totaled $54 million and included severance of $17 million for 372
employees, who left TI within three months of the related divestitures, $24
million for vendor and warranty obligations, which extend through 2002, $4
million for professional fees, and $9 million for various other costs. In the
fourth quarter of 1997, the company took a pretax charge of $42 million, of
which $30 million was included in cost of revenues and $12 million in marketing,
general and administrative expense, primarily for severance costs related to
cost-reduction actions by the materials & controls business. These actions,
which are expected to be completed in first-quarter 1999, affected approximately
260 employees. The terminated employees were in plants located in Holland,
Italy, Canada and Michigan. Costs of $5 million were paid by year-end 1998.
Remaining severance is to be paid in installments through 2002.

         In the fourth quarter of 1996, the company took a pretax charge of $208
million, of which $169 million was included in cost of revenues and $39 million
was included in marketing, general and administrative expense. Of the $208
million, $91 million was for severance for employment reduction actions in the
United States and selected reductions worldwide. These actions, which primarily
involved the semiconductor business as well as divested activities, were
essentially completed by year-end 1996 and affected approximately 2,600
employees. Of the severance cost of $91 million, $34 million was paid in 1996
and $57 million was paid in 1997. The balance of this charge, $117
million, was for vendor cancellation and other cash-related costs of $47 million
and asset write-downs of $70 million on several product lines, primarily mobile
computing, an operation divested in first-quarter 1997. The asset write-downs
were to adjust inventory and fixed assets to actual sale value. Of the $70
million asset write-down charge, $54 million was for mobile computing.

         With respect to this $54 million charge, $47 million was for inventory
and $7 million was for fixed assets. The balance of $16 million included a $6
million charge against operating assets for the impact of the expected first
quarter 1997 termination of TI's digital imaging printing development program.
The remainder, $10 million, was to write down the operating assets of TI's
Telecom business, which was held for sale.

BUSINESS SEGMENT AND GEOGRAPHIC AREA DATA

         Texas Instruments develops, manufactures and sells a variety of
products used in the commercial electronic and electrical equipment industry,
primarily for industrial and consumer markets. The company's principal
businesses are based on TI's broad semiconductor technology and application of
this technology to digital solutions for the networked society.

         TI HAS THREE PRINCIPAL BUSINESSES: Semiconductor, Materials & Controls
and Educational & Productivity Solutions. Each of these is a business segment,
with its respective financial performance detailed in this report.

         Semiconductor consists of digital signal processors, analog chips,
standard logic, application-specific integrated circuits, reduced
instruction-set computing microprocessors and microcontrollers. These
semiconductors are sold primarily to original-equipment manufacturers and
through distributors.

         Materials & Controls consists primarily of electrical and electronic
control devices, electronic connectors and clad metals. They are sold primarily
to original-equipment manufacturers and through distributors.

         Educational & Productivity Solutions, which includes educational and
graphing calculators, are marketed primarily through retailers and to schools
through instructional dealers.

         Operating profits of the three principal businesses include the effects
of profit sharing and exclude the effects of special charges and gains. The
results for semiconductor include the effects of all royalty revenues from
semiconductor-related cross-license agreements. Business assets are the owned or
allocated assets used by each business.

         Included in corporate activities are general corporate expenses,
elimination of intersegment transactions (which are generally intended to
approximate market prices), results for TI's emerging digital imaging operation
and royalty revenues from computer-related cross-license agreements. Assets of
corporate activities include unallocated cash, short-term investments,
noncurrent investments and deferred income taxes.

         Divested activities include the historical operating results and assets
of memory (sold in 1998), mobile computing and software (both sold in 1997),
custom manufacturing services and printers (both sold in 1996) and other smaller
divestitures.

         Included in the effect of non-U.S. rates for 1996 is a $4 million
benefit from tax loss carryforward utilization reduced by certain non-U.S. taxes
and losses for which no benefit was recognized. Provision has been made for
deferred taxes on undistributed earnings of non-U.S. subsidiaries to the extent
that dividend payments from such companies are expected to result in additional
tax liability. The remaining undistributed earnings (approximately $620 million
at December 31, 1998) have been indefinitely reinvested; therefore, no provision
has been made for taxes due upon remittance of these earnings. Determination of
the amount of unrecognized deferred tax liability on these unremitted earnings
is not practicable.

</TABLE>


         As of December 31, 1998 and 1997, the net deferred income tax asset of
$225 million and $423 million was presented in the balance sheet, based on tax
jurisdiction, as deferred income tax assets of $606 million and $711 million and
deferred income tax liabilities of $381 million and $288 million. The valuation
allowance shown above reflects the company's ongoing assessment regarding the
realizability of certain non-U.S. deferred income tax assets. The balance of the
deferred income tax assets is considered realizable based on carryback
potential, existing taxable temporary differences and expectation of future
income levels comparable to recent results. Such future income levels are not
assured because of the nature of the company's businesses, which are generally
characterized by rapidly changing technology and intense competition.

         The company has aggregate U.S. and non-U.S. tax loss carryforwards of
approximately $125 million. Of this amount, $117 million expires through the
year 2013, and $8 million of the loss carryforwards has no expiration.

         Income taxes paid were $162 million, $1145 million and $240 million for
1998, 1997 and 1996.

RENTAL EXPENSE AND LEASE COMMITMENTS

         Rental and lease expense was $153 million in 1998, $168 million in 1997
and $175 million in 1996. The company conducts certain operations in leased
facilities and also leases a portion of its data processing and other equipment.
The lease agreements


                                       49

frequently include purchase and renewal provisions and require the company to
pay taxes, insurance and maintenance costs.

         At December 31, 1998, the company was committed under noncancelable
leases with minimum rentals in succeeding years as follows:

DIVESTITURES

         In the first quarter of 1998, TI's U.S. DRAM semiconductor
manufacturing joint venture with Hitachi, Ltd. was discontinued as a result of a
combination of severe price declines and overcapacity in the DRAM market. As
part of this first quarter discontinuance, TI purchased the assets of the
venture for approximately $98 million. Also as part of this first quarter
discontinuance, TI and Hitachi decided to assume and share equally in the
payment of the venture's obligations. TI's share of those payments was $219
million, which was paid and charged to cost of revenues in the first quarter.

         In the second quarter of 1998, the company sold its interest in the
TI-Acer DRAM manufacturing joint venture to Acer Corporation for $120 million in
cash. This sale resulted in a pretax gain of $83 million. On September 30, 1998,
TI sold its memory business, including its remaining DRAM manufacturing joint
venture interests in TECH Semiconductor Singapore (TECH) and KTI Semiconductor
in Japan to Micron Technology, Inc. (Micron). As a result, TI received
28,933,092 Micron common shares, a $740 million note convertible into an
additional 12,333,358 Micron common shares and a $210 million subordinated note.
The $740 million face amount Micron convertible note contains an embedded call
option that allows TI to convert the note, at any time prior to its 2005
maturity, into 12,333,358 Micron common shares, at an effective conversion price
equal to $60 per common share. The market value of the seven year, 6.5%
convertible and subordinated notes was approximately $836 million at closing,
with an average imputed interest rate of 8.7%. In addition to TI's memory
assets, Micron received $550 million in cash from TI to facilitate the
deployment of Micron's technology throughout the acquired business. In the
fourth quarter of 1998, TI made an additional $130 million payment to Micron as
part of the contractually required working capital. TI deferred the estimated
pretax gain of $127 million on the sale until the recovery of the TI-provided
financing. The deferred gain is subject to change to the extent actual
transaction costs vary from estimates. In connection with the sale, TI agreed to
guarantee the payment obligations of TECH under a newly syndicated $450 million
principal amount credit facility for debt maturing 2002. As of year-end 1998,
TECH had borrowed $240 million under the facility. As a result of the guarantee,
TI was granted a security interest in TECH's assets. In addition, the guarantee
is partially offset by certain contingent funding obligations of TECH's
shareholders. In another matter, approximately $300 million of grants from the
Italian government to TI's former memory operations in Italy are being reviewed
in the ordinary course by government auditors. TI understands that these
auditors are questioning whether some of the grants were applied to purposes
outside the scope of the grants. TI's deferred gain on the sale may be reduced
to the extent that any grants are determined to have been misapplied. Also, TI
understands that an Italian prosecutor is conducting a


                                       50
<PAGE>   51


criminal investigation concerning a portion of the grants relating to specified
research and development activities. TI believes that the grants were obtained
and used in compliance with applicable law and contractual obligations.

         In July, 1997 the company sold its Defense Systems and Electronics
business (DSE) to Raytheon Company for $2.95 billion in cash. The net gain on
sale of this discontinued operation, after income taxes of $876 million, was
$1473 million. The consolidated financial statements of TI present the DSE
operations as discontinued operations. Summarized results of discontinued
operations prior to the close were as follows:

Income from discontinued operations                  52       109
</TABLE>


         TI provided various ongoing services to DSE including, but not limited
to, facilities management, data processing, security, payroll and employee
benefits administration, insurance administration and duplicating and
telecommunications services. Their inclusion in discontinued operations was
based upon TI's intercorporate allocation procedures for such services. The
allocation basis of these expenses and all other central operating costs was
first on the basis of direct usage when identifiable, with the remainder
allocated among DSE and other TI businesses on the basis of their respective
revenues, head count or other measures. These expenses allocated to DSE totaled
$76 million in 1997 and $163 million in 1996. TI has agreements to receive
payments from Raytheon for continuing to provide certain of these services on an
ongoing basis and others on a transition basis to DSE.

         At the request of the Securities and Exchange Commission, the results
of operations for the second and third quarters of 1998 have been restated to
reflect the shift of $14 million of pretax manufacturing costs from the second
quarter to the third quarter. The $14 million, which was previously recorded as
part of a $55 million asset write-down in the second quarter, is now reflected
as


                                       54

accelerated depreciation in the third quarter for assets phased out in that
quarter in connection with the winding down of production at a semiconductor
manufacturing facility located in Singapore. This restatement increased net
income and diluted earnings per share by $9 million and $0.02 in the second
quarter, and decreased these items by the same amounts in the third quarter. The
restatement had no impact on the Company's revenues or earnings for the year.

         Results for the first quarter of 1998 include a pretax charge of $219
million, included in cost of revenues, for discontinuance of the TI-Hitachi
joint venture and a charge of $25 million for the value of acquired research and
development from two business acquisitions. The second quarter of 1998 includes
a pretax operating charge of $219 million for a severance/manufacturing
efficiency program and a pretax gain of $83 million for the company's sale of
its interest in the TI-Acer joint venture. The third quarter of 1998 includes a
pretax operating charge of $14 million relating to the severance/manufacturing
efficiency program implemented during the second quarter of 1998. Fourth-quarter
1998 results include a pretax operating charge of $72 million, essentially all
of which is for the disposition of two European operations. In the first quarter
of 1997, the company took a pretax charge of $56 million related to the sale of
its mobile computing business and termination of its digital imaging printing
development program. Results for the second quarter of 1997 include a pretax
operating charge of $44 million for the termination of agreements related to
proposed Thailand joint ventures and a $66 million pretax gain from the sale of
three divested activities, principally software. Results for the third quarter
of 1997 reflect the sale of TI's defense business, which was closed with
Raytheon Company on July 11 for $2.95 billion in cash. The net gain from this
sale, after income taxes of $876 million, was $1473 million and was included in
discontinued operations. As a result of the 1997 acquisition of Amati
Communications Corporation, the company took a charge of $461 million in the
fourth quarter for the value of acquired in-process research and development.
Also in the fourth quarter, the company took a pretax charge of $42 million,
primarily for severance costs related to cost-reduction actions by the materials
& controls business. Diluted earnings (loss) per common share are based on
average common and dilutive potential common shares outstanding (402,230,699
shares and 389,695,136 shares for the fourth quarters of 1998 and 1997).

the safe harbor from liability established by the Private Securities Litigation
Reform Act of


                                       59

1995. These forward-looking statements generally can be identified by phrases
such as TI or its management "believes," "expects," "anticipates," "foresees,"
"forecasts," "estimates" or other words or phrases of similar import. Similarly,
such statements herein that describe TI's business strategy, outlook,
objectives, plans, intentions or goals also are forward-looking statements. All
such forward-looking statements are subject to certain risks and uncertainties
that could cause actual results to differ materially from those in
forward-looking statements.

We urge you to carefully consider the following important factors that could
cause actual results to differ materially from the expectations of TI or its
management:

- -    Market demand for semiconductors, particularly for digital signal
     processors and analog integrated circuits in key markets, such as
     telecommunications and computers.

- -    TI's ability to develop, manufacture and market innovative products in a
     rapidly changing technological environment.

- -    TI's ability to compete in products and prices in an intensely competitive
     industry.

- -    TI's ability to maintain and enforce a strong intellectual property
     portfolio and obtain needed licenses from third parties.

- -    Timely completion by customers and suppliers of their Year 2000 programs,
     as well as accurate assessment of TI's Year 2000 readiness and effective
     implementation of corrective actions.

- -    Timely completion of announced acquisitions.

- -    Global economic, social and political conditions in the countries in which
     TI and its customers and suppliers operate, including fluctuations in
     foreign currency exchange rates.

- -    Losses or curtailments of purchases from key customers or the timing of
     customer inventory corrections.

- -    TI's ability to recruit and retain skilled personnel.

- -    Availability of raw materials and critical manufacturing equipment.

- -    Realization of savings from announced worldwide corporate restructuring
     efforts and consolidation of manufacturing operations.

For a more detailed discussion of these factors see the text under the heading
"Cautionary Statements Regarding Future Operations" in Item 1 of this Form 10-K
as originally filed. The forward-looking statements included in this Form 10-K/A
are made only as of the date of this Form 10-K/A and TI undertakes no
obligation to publicly update the forward-looking statements to reflect
subsequent events or circumstances.
