                          LINEAR TECHNOLOGY CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.       Interim financial statements and information are unaudited; however, in
         the opinion of  management  all  adjustments  necessary  for a fair and
         accurate  presentation  of the interim results have been made. All such
         adjustments  were of a normal  recurring  nature.  The  results for the
         three and six months  ended  December 29, 2002 are not  necessarily  an
         indication  of results to be expected for the entire  fiscal year.  All
         information  reported in this Form 10-Q  should be read in  conjunction
         with the Company's  annual  consolidated  financial  statements for the
         fiscal year ended June 30, 2002 included in the Company's Annual Report
         to Stockholders.  The  accompanying  balance sheet at June 30, 2002 has
         been derived from audited financial statements as of that date. Because
         the  Company is viewed as a single  operating  segment  for  management
         purposes, no segment information has been disclosed.

2.       The Company  operates on a 52/53 week year ending on the Sunday nearest
         June 30. Fiscal years 2003 and 2002 are 52-week years.

3.       Basic  earnings  per share is  calculated  using the  weighted  average
         shares of common stock outstanding during the period.  Diluted earnings
         per share is  calculated  using the weighted  average  shares of common
         stock outstanding, plus the dilutive effect of stock options calculated
         using the treasury  stock method.  The  following  table sets forth the
         reconciliation  of weighted  average common shares  outstanding used in
         the computation of basic and diluted earnings per share:

4.       Accumulated Other Comprehensive Income

         Accumulated other comprehensive  income consists of unrealized gains on
         available-for-sale  securities.  The Company,  in  practice,  primarily
         holds  its  cash  and  short-term   investments  until  maturity.   The
         components of comprehensive income were as follows:

5.       Recent Accounting Pronouncements

         In June 2001, the Financial  Accounting  Standards  Board (FASB) issued
         Statement of Financial Accounting Standards No. 142 "Goodwill and Other
         Intangible  Assets"  (SFAS 142.) SFAS 142  requires  that  goodwill and
         indefinite  lived  intangible  assets are no longer  amortized  but are
         reviewed  annually (or more frequently if impairment  indicators arise)
         for impairment. Separable intangible assets that are not deemed to have
         an  indefinite  life will  continue to be  amortized  over their useful
         lives.  The Company  adopted SFAS 142 on July 1, 2002.  The adoption of
         SFAS 142 did not have any impact on the Company's financial position or
         results of operations.

         In October 2001, the Financial Accounting Standards Board (FASB) issued
         Statement of Financial  Accounting  Standards No. 143  "Accounting  for
         Asset  Retirement  Obligations"  (SFAS 143.) SFAS 143 requires that the
         fair value of asset retirement obligations be recognized as a liability
         when they are  incurred  and that the  associated  retirement  costs be
         capitalized as a long-term asset and expensed over its useful life. The
         Company  adopted SFAS 143 on July 1, 2002. The adoption of SFAS 143 did
         not have any impact on the Company's  financial  position or results of
         operations.

         In August 2001, the Financial  Accounting Standards Board (FASB) issued
         Statement of Financial  Accounting  Standards No. 144,  "Accounting for
         the  Impairment or Disposal of Long-Lived  Assets" (SFAS 144.) SFAS 144
         addresses  financial  accounting  and reporting  for the  impairment or
         disposal of long-lived  assets and supersedes  FAS No. 121,  Accounting
         for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
         Disposed Of, and the accounting and reporting provisions of APB No. 30,
         Reporting  the Results of  Operations  for a Disposal of a Segment of a
         Business. The Company adopted SFAS 144 on July 1, 2002. The adoption of
         SFAS 144 did not have any impact on the Company's financial position or
         results of operations.

         In June 2002, the Financial  Accounting  Standards  Board (FASB) issued
         Statement of Financial  Accounting  Standards No. 146,  "Accounting for
         Costs Associated with Exit or Disposal Activities" (SFAS 146.) SFAS 146
         addresses financial  accounting and reporting for costs associated with
         exit  or  disposal  activities  and  nullifies  EITF  Issue  No.  94-3,
         "Liability  Recognition for Certain Employee  Termination  Benefits and
         Other Costs to Exit an Activity  (including Certain Costs Incurred in a
         Restructuring)" and must be applied beginning January 1, 2003. SFAS 146
         requires  that a  liability  for a cost  associated  with  an  exit  or
         disposal  activity be recognized  when the liability is incurred rather
         than when the exit or disposal  plan is approved.  The Company does not
         expect that the adoption of SFAS 146 will have a significant  effect on
         its financial position or results of operations.

         Net sales for the quarter ended December 29, 2002 were $145.0  million,
an increase of $23.8 million or 19.6% over net sales for the same quarter of the
previous year. The increase in net sales was due to higher unit shipments, which
was offset by a decrease in the average  selling price.  The decrease in average
selling  price is the result of a  continuing  change in mix to smaller  package
products  and due to  slight  price  reductions.  Sales  increased  in all major
geographic  areas  in  absolute  dollars,  led by rest of the  world,  which  is
primarily Asia excluding Japan, followed by Japan, Europe and the United States.
International  sales were  approximately 68% of net sales for the second quarter
of  fiscal  2003  compared  to 63%  for  the  second  quarter  of  fiscal  2002.
International  geographies  as a percent of worldwide  net sales were Japan 15%,
Europe 18%, and rest of world 35%. Domestic sales were  approximately 32% of net
sales for the  second  quarter  of fiscal  2003  compared  to 37% for the second
quarter  of  fiscal  2002.  The  Company's  major  end-market  applications  are
communications,  industrial and computer.  Sales increased over the prior year's
quarter in all end-market applications, led by communications.

         Net sales for the six months ended  December 29, 2002  increased  $45.7
million or 18.9% over net sales for the same period of the previous fiscal year.
The increase in net sales was due to higher unit shipments,  which was offset by
a decrease in the average selling price. Sales increased in all geographic areas
in absolute dollars, led by rest of the world, followed by Japan, Europe and the
United States.  Relative to end-market  applications,  sales  increased over the
prior year's six month in each of the Company's  three major  end-markets led by
communications.

         During the second  quarter of fiscal 2003, the Company had two one-week
shutdowns during the holiday weeks of Thanksgiving and Christmas.  This resulted
in one less week of shutdown when compared to the second quarter of the previous
fiscal  year.  For the first six months of fiscal 2003 the Company had four less
one-week  shutdowns compared to the

                                       9


same period in the previous  fiscal year. Due to having fewer  shutdowns  during
the  second  quarter  and for the first  six-months,  the  Company  had  greater
compensation costs throughout the cost of sales and operating expense lines. The
impact of fewer  shutdowns  was  somewhat  offset  by  reductions  in  workforce
associated with the closing of the Company's oldest wafer  fabrication  plant in
Milpitas, California in the previous fiscal year.

         Gross profit  increased $21.3 million or 25% and $43.8 million or 26.1%
for the second quarter and first six months of fiscal 2003,  respectively,  over
the  corresponding  periods in fiscal  2002.  The  increase in gross profit as a
percentage  of net sales for both  periods was  primarily  due to the  favorable
effect  of  fixed  costs  allocated  across  a  higher  sales  base as well as a
reduction in headcount  expenses  from the previous  fiscal year as discussed in
the previous  paragraph.  This effect was somewhat  offset by reduced  inventory
absorption and severance  packages  caused by modest  reductions in workforce at
the Camas,  Washington  wafer  fabrication  plant  during the second  quarter of
fiscal 2003.  The decrease in average  selling  price  referred to above did not
have a  commensurate  effect on gross margin since most of the reduction was due
to a change in product mix as the Company  has had  increased  sales of products
with smaller die and package types,  which have a smaller  average selling price
but also lower costs.

         Research and development  ("R&D") expenses increased by $2.0 million or
10.1% and $6.2  million or 16.3% for the second  quarter and first six months of
fiscal 2003,  respectively,  as compared to the same periods in fiscal 2002. The
increase in R&D  expenses  compared to the prior year  periods was mainly due to
increases  in labor  expenses  primarily  related to  increases  in  engineering
headcount,  profit sharing,  and the impact of less shutdowns during the periods
as explained  above.  The  increases in labor costs were offset by a decrease in
mask costs.

         Selling, general and administrative expenses ("SG&A") increased by $2.3
million or 16.5% and $3.1 million or 10.3% for the second  quarter and first six
months of fiscal 2003,  respectively,  as compared to the same periods in fiscal
2002.  The increase in SG&A  expenses  compared to the prior year period was due
primarily to labor related expenses for increased  profit sharing,  increases in
commissions  due to higher sales,  and the impact of less  shutdowns  during the
periods as explained above.

         Interest  income was $10.5  million  and $20.9  million  for the second
quarter and first six months of fiscal 2003, a decrease of $2.6 million and $8.0
million  respectively,  from the  corresponding  periods  of  fiscal  2002.  The
interest  income earned on the increase in the Company's  cash  equivalents  and
short-term  investment  balance was more than offset by a decline in the average
interest rates from period to period.  The decrease in the interest rate was the
result of the  Federal  Funds  rate  dropping  from the 2.0% range in the second
quarter of fiscal 2002 to 1.25% in the second quarter of fiscal 2003.

         The Company's  effective tax rate for the second  quarter and first six
months of fiscal  2003 and 2002 was 29%.  The tax rate is  impacted  by business
activity in foreign  jurisdictions with lower tax rates and tax-exempt  interest
income.

Factors Affecting Future Operating Results

         Except for historical  information  contained  herein,  the matters set
forth in this Form 10-Q,  including the statements in the following  paragraphs,
are  forward-looking   statements  that  are  dependent  on  certain  risks  and
uncertainties  including such factors,  among others, as the timing,  volume and
pricing of new orders  received  and  shipped  during  the  quarter,  the timely
introduction  of new  processes and  products,  general  conditions in the world
economy and financial  markets and other factors described below and in our 10-K
for the fiscal year ended June 30, 2002.

         The quarter  just  completed  had improved  financial  results over the
previous  quarter and grew notably over the same quarter in the previous  fiscal
year.  The Company's  backlog coming out of the second quarter of fiscal 2003 is
up  modestly  from the  first  quarter  of  fiscal  2003,  which is still low by
historic  standards,  but within a range that the Company has operated  under in
the past year.  The  conditions  external to the Company  remain  unchanged,  as
general global economic and political  conditions remain causes for concern. The
March  quarter  is  customarily  a stronger  quarter  for the  Company  then the
December  quarter,  due to more business days  resulting  from fewer holidays in
Europe and the USA. For an extended period,  the US market has been weak for the
Company,  however the  Company has begun to see a moderate  pick-up in quote and
forecasting activity across all end-markets in the USA.  Consequently,  although
confidently and accurately forecasting short-term future results is difficult in
this environment,  when weighing all the factors,  including  modestly improving
bookings, good positioning in new programs,  responsive lead times, and seasonal
strength in the USA,  partially  offset by customer  conservatism in response to
worldwide economic and political concerns,  the Company estimates that sales and
profits in the current  quarter will grow in the middle single digits,  3% to 7%
from the December quarter.

         Estimates of future performance are uncertain,  and past performance of
the Company may not be a good  indicator  of future  performance  due to factors
affecting  the Company,  its  competitors,  the  semiconductor  industry and the
overall  economy.   The   semiconductor   industry  is  characterized  by  rapid
technological  change,  price  erosion,   cyclical  market  patterns,   periodic
oversupply conditions,  occasional shortages of materials, capacity constraints,
variations  in  manufacturing  efficiencies  and  significant  expenditures  for
capital   equipment   and   product   development.   Furthermore,   new  product
introductions  and patent protection of existing  products,  as well as exposure
related to patent  infringement  suits  brought  against the Company are factors
that  can  influence  future  sales  growth  and  sustained  profitability.  The
Company's  headquarters  and a  portion  of  its  manufacturing  facilities  and
research  and  development   activities  and  certain  other  critical  business
operations  are  located  near  major  earthquake  fault  lines  in  California,
consequently,  the Company  could be adversely  affected in the event of a major
earthquake.

         Although  the  Company   believes  that  it  has  the  product   lines,
manufacturing  facilities and technical and financial  resources for its current
operations, sales and profitability could be significantly affected by the above
and other factors.  Additionally, the Company's common stock could be subject to
significant   price  volatility  should  sales  and/or  earnings  fail  to  meet
expectations of the investment community. Furthermore, stocks of high technology
companies  are subject to extreme price and volume  fluctuations  that are often
unrelated or disproportionate to the operating performance of these companies.

Liquidity and Capital Resources

         At December 29, 2002, cash, cash equivalents and short-term investments
totaled $1,548.8 million, and working capital was $1,588.3 million.

         Accounts  receivable  totaled  $91.8  million  at the end of the second
quarter of fiscal 2003, an increase of $10.4 million from the fourth  quarter of
fiscal  2002.  The  increase is due to higher  sales and days sales  outstanding
(DSO)  increasing from the fourth quarter.  Compared with the similar quarter in
the prior fiscal year, DSO in accounts receivable was the same at 58 days.

         Income taxes  payable  totaled  $43.4  million at the end of the second
quarter of fiscal  2003 a decrease  of $20  million  from the fourth  quarter of
fiscal 2002.  The decrease is the result of federal tax payments made during the
second quarter of fiscal 2003.

         During  the first six  months of fiscal  2003,  the  Company  generated
$119.5 million of cash from  operating  activities and $22.7 million in proceeds
from common stock issued under employee stock plans. Additionally,  net proceeds
from the  purchase,  sale and maturity of  short-term  investments  totaled $4.7
million.

         During  the  first  six  months  of  fiscal  2003,   significant   cash
expenditures  included repurchasing $126.5 million of common stock, paying $31.4
million  in cash  dividends  to  stockholders  representing  $0.05 per share per
quarter,  and  spending  $3.2 million for the  purchase of capital  assets.  The
payment of future dividends will be based on quarterly financial performance.

         As of December 29, 2002, the Company had no off-balance sheet financing
arrangements  or activities  other than minimal  levels of operating  leases for
facilities and equipment.

         Historically,  the Company has satisfied  its  liquidity  needs through
cash generated from operations and the placement of equity securities. Given its
strong financial  condition and  performance,  the Company believes that current
capital  resources  and  cash  generated  from  operating   activities  will  be
sufficient to meet its liquidity and capital  expenditures  requirements for the
foreseeable future.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

         For additional  quantitative and qualitative  disclosures  about market
risk  affecting  the Company,  see item 7A of the 10-K for the fiscal year ended
June 30, 2002.  There have been no material changes in the market risk affecting
the Company  since the filing of the 10-K for fiscal 2002. At December 29, 2002,
the Company's cash and cash  equivalents  consisted  primarily of bank deposits,
commercial  paper and money market funds. The Company's  short-term  investments
consisted of  commercial  paper,  municipal  bonds,  federal  agency and related
securities.  The Company did not hold any derivative financial instruments.  The
Company's  interest  income is  sensitive  to  changes in the  general  level of
interest  rates.  In this  regard,  changes  in  interest  rates can  affect the
interest earned on cash and cash equivalents and short-term investments.

                                       11


Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures

Within the 90-day period prior to the date of this report,  the Company  carried
out an  evaluation,  under the  supervision  and with the  participation  of the
Company's management,  including the Company's Chief Executive Officer and Chief
Financial  Officer,  of the  effectiveness  of the design and  operation  of the
Company's  disclosure  controls  and  procedures  pursuant to Rule 13a-14 of the
Securities   Exchange  Act  of  1934  (the  "Exchange  Act").  Based  upon  that
evaluation,  the Chief Executive  Officer and Chief Financial  Officer concluded
that the Company's  disclosure  controls and  procedures are effective in timely
alerting them to material  information  relating to the Company  (including  its
consolidated subsidiaries) required to be included in the Company's Exchange Act
filings.

(b) Changes in internal controls

There have been no significant  changes in the Company's internal controls or in
other factors,  which could significantly affect internal controls subsequent to
the date the Company carried out its evaluation.
